                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2002), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

OBSOLETE PROVISIONS

    Provisions that become obsolete before the revision date stated on 
the cover of each volume are not carried. Code users may find the text 
of provisions in effect on a given date in the past by using the 
appropriate numerical list of sections affected. For the period before 
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For 
the period beginning January 1, 1986, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    Properly approved incorporations by reference in this volume are 
listed in the Finding Aids at the end of this volume.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed in 
the Finding Aids of this volume as an approved incorporation by 
reference, please contact the agency that issued the regulation 
containing that incorporation. If, after contacting the agency, you find 
the material is not available, please notify the Director of the Federal 
Register, National Archives and Records Administration, Washington DC 
20408, or call (202) 523-4534.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Statutory 
Authorities and Agency Rules (Table I). A list of CFR titles, chapters, 
and parts and an alphabetical list of agencies publishing in the CFR are 
also included in this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

 Subpart C--Recyclable Materials Used in a Manner Constituting Disposal



Sec. 266.20  Applicability.

    (a) The regulations of this subpart apply to recyclable materials 
that are applied to or placed on the land:
    (1) Without mixing with any other substance(s); or
    (2) After mixing or combination with any other substance(s). These 
materials will be referred to throughout this subpart as ``materials 
used in a manner that constitutes disposal.''
    (b) Products produced for the general public's use that are used in 
a manner that constitutes disposal and that contain recyclable materials 
are not presently subject to regulation if the recyclable materials have 
undergone a chemical reaction in the course of producing the products so 
as to become inseparable by physical means and if such products meet the 
applicable treatment standards in subpart D of part 268 (or applicable 
prohibition levels in Sec. 268.32 or RCRA section 3004(d), where no 
treatment standards have been established) for each recyclable material 
(i.e., hazardous waste) that they contain. Commercial fertilizers that 
are produced for the general public's use that contain recyclable 
materials also are not presently subject to regulation provided they 
meet these same treatment standards or prohibition levels for each 
recyclable material that they contain. However, zinc-containing 
fertilizers using hazardous waste K061 that are produced for the general 
public's use are not presently subject to regulation.
    (c) Anti-skid/deicing uses of slags, which are generated from high 
temperature metals recovery (HTMR) processing of hazardous waste K061, 
K062, and F006, in a manner constituting disposal are not covered by the 
exemption in paragraph (b) of this section and remain subject to 
regulation.

  Subpart H--Hazardous Waste Burned in Boilers and Industrial Furnaces

    Source: 56 FR 7208, Feb. 21, 1991, unless otherwise noted.



Sec. 266.100  Applicability.

    (a) The regulations of this subpart apply to hazardous waste burned 
or processed in a boiler or industrial furnace (as defined in 
Sec. 260.10 of this chapter) irrespective of the purpose of burning or 
processing, except as provided by paragraphs (b), (c), (d), (g), and (h) 
of this section. In this subpart, the term ``burn'' means burning for 
energy recovery or destruction, or processing for materials recovery or 
as an ingredient. The emissions standards of Secs. 266.104, 266.105, 
266.106, and 266.107 apply to facilities operating under interim status 
or under a RCRA permit as specified in Secs. 266.102 and 266.103.
    (b) Integration of the MACT standards. (1) Except as provided by 
paragraph (b)(2) of this section, the standards of this part no longer 
apply when an affected source demonstrates compliance with the maximum 
achievable control technology (MACT) requirements of part 63, subpart 
EEE, of this chapter by conducting a comprehensive performance test and 
submitting to the Administrator a Notification of Compliance under 
Secs. 63.1207(j) and 63.1210(b) of this chapter documenting compliance 
with the requirements of part 63, subpart EEE, of this chapter. 
Nevertheless, even after this demonstration of compliance with the MACT 
standards, RCRA permit conditions that were based on the standards of 
this part will continue to be in effect until they are removed from the 
permit or the permit is terminated or revoked, unless the permit 
expressly provides otherwise.
    (2) The following standards continue to apply:
    (i) If you elect to comply with Sec. 270.235(a)(1)(i) of this 
chapter to minimize emissions of toxic compounds from startup, shutdown, 
and malfunction events, Sec. 266.102(e)(1) requiring operations in 
accordance with the operating requirements specified in the permit at 
all times that hazardous waste

[[Page 11]]

is in the unit, and Sec. 266.102(e)(2)(iii) requiring compliance with 
the emission standards and operating requirements during startup and 
shutdown if hazardous waste is in the combustion chamber, except for 
particular hazardous wastes. These provisions apply only during startup, 
shutdown, and malfunction events;
    (ii) The closure requirements of Secs. 266.102(e)(11) and 
266.103(l);
    (iii) The standards for direct transfer of Sec. 266.111;
    (iv) The standards for regulation of residues of Sec. 266.212; and
    (v) The applicable requirements of subparts A through H, BB and CC 
of parts 264 and 265 of this chapter.
    (c) The following hazardous wastes and facilities are not subject to 
regulation under this subpart:
    (1) Used oil burned for energy recovery that is also a hazardous 
waste solely because it exhibits a characteristic of hazardous waste 
identified in subpart C of part 261 of this chapter. Such used oil is 
subject to regulation under part 279 of this chapter;
    (2) Gas recovered from hazardous or solid waste landfills when such 
gas is burned for energy recovery;
    (3) Hazardous wastes that are exempt from regulation under 
Secs. 261.4 and 261.6(a)(3) (iii) and (iv) of this chapter, and 
hazardous wastes that are subject to the special requirements for 
conditionally exempt small quantity generators under Sec. 261.5 of this 
chapter; and
    (4) Coke ovens, if the only hazardous waste burned is EPA Hazardous 
Waste No. K087, decanter tank tar sludge from coking operations.
    (d) Owners and operators of smelting, melting, and refining furnaces 
(including pyrometallurgical devices such as cupolas, sintering 
machines, roasters, and foundry furnaces, but not including cement 
kilns, aggregate kilns, or halogen acid furnaces burning hazardous 
waste) that process hazardous waste solely for metal recovery are 
conditionally exempt from regulation under this subpart, except for 
Secs. 266.101 and 266.112.
    (1) To be exempt from Secs. 266.102 through 266.111, an owner or 
operator of a metal recovery furnace or mercury recovery furnace must 
comply with the following requirements, except that an owner or operator 
of a lead or a nickel-chromium recovery furnace, or a metal recovery 
furnace that burns baghouse bags used to capture metallic dusts emitted 
by steel manufacturing, must comply with the requirements of paragraph 
(d)(3) of this section, and owners or operators of lead recovery 
furnaces that are subject to regulation under the Secondary Lead 
Smelting NESHAP must comply with the requirements of paragraph (h) of 
this section.
    (i) Provide a one-time written notice to the Director indicating the 
following:
    (A) The owner or operator claims exemption under this paragraph;
    (B) The hazardous waste is burned solely for metal recovery 
consistent with the provisions of paragraph (d)(2) of this section;
    (C) The hazardous waste contains recoverable levels of metals; and
    (D) The owner or operator will comply with the sampling and analysis 
and recordkeeping requirements of this paragraph;
    (ii) Sample and analyze the hazardous waste and other feedstocks as 
necessary to comply with the requirements of this paragraph under 
procedures specified by Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods, SW-846, incorporated by reference in 
Sec. 260.11 of this chapter or alternative methods that meet or exceed 
the SW-846 method performance capabilities. If SW-846 does not prescribe 
a method for a particular determination, the owner or operator shall use 
the best available method; and
    (iii) Maintain at the facility for at least three years records to 
document compliance with the provisions of this paragraph including 
limits on levels of toxic organic constituents and Btu value of the 
waste, and levels of recoverable metals in the hazardous waste compared 
to normal nonhazardous waste feedstocks.
    (2) A hazardous waste meeting either of the following criteria is 
not processed solely for metal recovery:
    (i) The hazardous waste has a total concentration of organic 
compounds listed in part 261, appendix VIII, of this chapter exceeding 
500 ppm by weight, as-fired, and so is considered to be

[[Page 12]]

burned for destruction. The concentration of organic compounds in a 
waste as-generated may be reduced to the 500 ppm limit by bona fide 
treatment that removes or destroys organic constituents. Blending for 
dilution to meet the 500 ppm limit is prohibited and documentation that 
the waste has not been impermissibly diluted must be retained in the 
records required by paragraph (d)(1)(iii) of this section; or
    (ii) The hazardous waste has a heating value of 5,000 Btu/lb or 
more, as-fired, and so is considered to be burned as fuel. The heating 
value of a waste as-generated may be reduced to below the 5,000 Btu/lb 
limit by bona fide treatment that removes or destroys organic 
constituents. Blending for dilution to meet the 5,000 Btu/lb limit is 
prohibited and documentation that the waste has not been impermissibly 
diluted must be retained in the records required by paragraph 
(d)(1)(iii) of this section.
    (3) To be exempt from Secs. 266.102 through 266.111, an owner or 
operator of a lead or nickel-chromium or mercury recovery furnace 
(except for owners or operators of lead recovery furnaces subject to 
regulation under the Secondary Lead Smelting NESHAP) or a metal recovery 
furnace that burns baghouse bags used to capture metallic dusts emitted 
by steel manufacturing, must provide a one-time written notice to the 
Director identifying each hazardous waste burned and specifying whether 
the owner or operator claims an exemption for each waste under this 
paragraph or paragraph (d)(1) of this section. The owners or operator 
must comply with the requirements of paragraph (d)(1) of this section 
for those wastes claimed to be exempt under that paragraph and must 
comply with the requirements below for those wastes claimed to be exempt 
under this paragraph (d)(3).
    (i) The hazardous wastes listed in appendices XI, XII, and XIII, 
part 266, and baghouse bags used to capture metallic dusts emitted by 
steel manufacturing are exempt from the requirements of paragraph (d)(1) 
of this section, provided that:
    (A) A waste listed in appendix IX of this part must contain 
recoverable levels of lead, a waste listed in appendix XII of this part 
must contain recoverable levels of nickel or chromium, a waste listed in 
appendix XIII of this part must contain recoverable levels of mercury 
and contain less than 500 ppm of 40 CFR part 261, appendix VIII organic 
constituents, and baghouse bags used to capture metallic dusts emitted 
by steel manufacturing must contain recoverable levels of metal; and
    (B) The waste does not exhibit the Toxicity Characteristic of 
Sec. 261.24 of this chapter for an organic constituent; and
    (C) The waste is not a hazardous waste listed in subpart D of part 
261 of this chapter because it is listed for an organic constituent as 
identified in appendix VII of part 261 of this chapter; and
    (D) The owner or operator certifies in the one-time notice that 
hazardous waste is burned under the provisions of paragraph (d)(3) of 
this section and that sampling and analysis will be conducted or other 
information will be obtained as necessary to ensure continued compliance 
with these requirements. Sampling and analysis shall be conducted 
according to paragraph (d)(1)(ii) of this section and records to 
document compliance with paragraph (d)(3) of this section shall be kept 
for at least three years.
    (ii) The Director may decide on a case-by-case basis that the toxic 
organic constituents in a material listed in appendix XI, XII, or XIII 
of this part that contains a total concentration of more than 500 ppm 
toxic organic compounds listed in appendix VIII, part 261 of this 
chapter, may pose a hazard to human health and the environment when 
burned in a metal recovery furnace exempt from the requirements of this 
subpart. In that situation, after adequate notice and opportunity for 
comment, the metal recovery furnace will become subject to the 
requirements of this subpart when burning that material. In making the 
hazard determination, the Director will consider the following factors:
    (A) The concentration and toxicity of organic constituents in the 
material; and
    (B) The level of destruction of toxic organic constituents provided 
by the furnace; and

[[Page 13]]

    (C) Whether the acceptable ambient levels established in appendices 
IV or V of this part may be exceeded for any toxic organic compound that 
may be emitted based on dispersion modeling to predict the maximum 
annual average off-site ground level concentration.
    (e) The standards for direct transfer operations under Sec. 266.111 
apply only to facilities subject to the permit standards of Sec. 266.102 
or the interim status standards of Sec. 266.103.
    (f) The management standards for residues under Sec. 266.112 apply 
to any boiler or industrial furnace burning hazardous waste.
    (g) Owners and operators of smelting, melting, and refining furnaces 
(including pyrometallurgical devices such as cupolas, sintering 
machines, roasters, and foundry furnaces) that process hazardous waste 
for recovery of economically significant amounts of the precious metals 
gold, silver, platinum, paladium, irridium, osmium, rhodium, or 
ruthenium, or any combination of these are conditionally exempt from 
regulation under this subpart, except for Sec. 266.112. To be exempt 
from Secs. 266.101 through 266.111, an owner or operator must:
    (1) Provide a one-time written notice to the Director indicating the 
following:
    (i) The owner or operator claims exemption under this paragraph;
    (ii) The hazardous waste is burned for legitimate recovery of 
precious metal; and
    (iii) The owner or operator will comply with the sampling and 
analysis and recordkeeping requirements of this paragraph; and
    (2) Sample and analyze the hazardous waste as necessary to document 
that the waste is burned for recovery of economically significant 
amounts of precious metal using procedures specified by Test Methods for 
Evaluating Solid Waste, Physical/Chemical Methods, SW-846, incorporated 
by reference in Sec. 260.11 of this chapter or alternative methods that 
meet or exceed the SW-846 method performance capabilities. If SW-846 
does not prescribe a method for a particular determination, the owner or 
operator shall use the best available method; and
    (3) Maintain at the facility for at least three years records to 
document that all hazardous wastes burned are burned for recovery of 
economically significant amounts of precious metal.
    (h) Starting June 23, 1997, owners or operators of lead recovery 
furnaces that process hazardous waste for recovery of lead and that are 
subject to regulation under the Secondary Lead Smelting NESHAP, are 
conditionally exempt from regulation under this subpart, except for 
Sec. 266.101. To be exempt, an owner or operator must provide a one-time 
notice to the Director identifying each hazardous waste burned and 
specifying that the owner or operator claims an exemption under this 
paragraph. The notice also must state that the waste burned has a total 
concentration of non-metal compounds listed in part 261, appendix VIII, 
of this chapter of less than 500 ppm by weight, as fired and as provided 
in paragraph (d)(2)(i) of this section, or is listed in appendix XI to 
this part 266.

Sec. 266.102  Permit standards for burners.

    (a) Applicability--(1) General. Owners and operators of boilers and 
industrial furnaces burning hazardous waste and not operating under 
interim status must comply with the requirements of this section and 
Secs. 270.22 and 270.66 of this chapter, unless exempt under the small 
quantity burner exemption of Sec. 266.108.
    (2) Applicability of part 264 standards. Owners and operators of 
boilers and industrial furnaces that burn hazardous waste are subject to 
the following provisions of part 264 of this chapter, except as provided 
otherwise by this subpart:
    (i) In subpart A (General), 264.4;
    (ii) In subpart B (General facility standards), Secs. 264.11-264.18;
    (iii) In subpart C (Preparedness and prevention), Secs. 264.31-
264.37;
    (iv) In subpart D (Contingency plan and emergency procedures), 
Secs. 264.51-264.56;
    (v) In subpart E (Manifest system, recordkeeping, and reporting), 
the applicable provisions of Secs. 264.71-264.77;
    (vi) In subpart F (Corrective Action), Secs. 264.90 and 264.101;
    (vii) In subpart G (Closure and post-closure), Secs. 264.111-

    (ix) Subpart BB (Air emission standards for equipment leaks), except 
Secs. 264.1050(a).
    (b) Hazardous waste analysis. (1) The owner or operator must provide 
an analysis of the hazardous waste that quantifies the concentration of 
any constituent identified in appendix VIII of part 261 of this chapter 
that may reasonably be expected to be in the waste. Such constituents 
must be identified and quantified if present, at levels detectable by 
analytical procedures prescribed by Test Methods for Evaluating Solid 
Waste, Physical/Chemical Methods (incorporated by reference, see 
Sec. 260.11 of this chapter). Alternative methods that meet or exceed 
the method performance capabilities of SW-846 methods may be used. If 
SW-846 does not prescribe a method for a particular determination, the 
owner or operator shall use the best available method. The appendix 
VIII, part 261 constituents excluded from this analysis must be 
identified and the basis for their exclusion explained. This analysis 
will be used to provide all information required by this subpart and 
Sec. 270.22 and Sec. 270.66 of this chapter and to enable the permit 
writer to prescribe such permit conditions as necessary to protect human 
health and the environment. Such analysis must be included as a portion 
of the part B permit application, or, for facilities operating under the 
interim status standards of this subpart, as a portion of the trial burn 
plan that may be submitted before the part B application under 
provisions of Sec. 270.66(g) of this chapter as well as any other 
analysis required by the permit authority in preparing the permit. 
Owners and operators of boilers and industrial furnaces not operating 
under the interim status standards must provide the information required 
by Secs. 270.22 or 270.66(c) of this chapter in the part B application 
to the greatest extent possible.
    (2) Throughout normal operation, the owner or operator must conduct 
sampling and analysis as necessary to ensure that the hazardous waste, 
other fuels, and industrial furnace feedstocks

[[Page 15]]

fired into the boiler or industrial furnace are within the physical and 
chemical composition limits specified in the permit.
    (c) Emissions standards. Owners and operators must comply with 
emissions standards provided by Secs. 266.104 through 266.107.
    (d) Permits. (1) The owner or operator may burn only hazardous 
wastes specified in the facility permit and only under the operating 
conditions specified under paragraph (e) of this section, except in 
approved trial burns under the conditions specified in Sec. 270.66 of 
this chapter.
    (2) Hazardous wastes not specified in the permit may not be burned 
until operating conditions have been specified under a new permit or 
permit modification, as applicable. Operating requirements for new 
wastes may be based on either trial burn results or alternative data 
included with part B of a permit application under Sec. 270.22 of this 
chapter.
    (3) Boilers and industrial furnaces operating under the interim 
status standards of Sec. 266.103 are permitted under procedures provided 
by Sec. 270.66(g) of this chapter.
    (4) A permit for a new boiler or industrial furnace (those boilers 
and industrial furnaces not operating under the interim status 
standards) must establish appropriate conditions for each of the 
applicable requirements of this section, including but not limited to 
allowable hazardous waste firing rates and operating conditions 
necessary to meet the requirements of paragraph (e) of this section, in 
order to comply with the following standards:
    (i) For the period beginning with initial introduction of hazardous 
waste and ending with initiation of the trial burn, and only for the 
minimum time required to bring the device to a point of operational 
readiness to conduct a trial burn, not to exceed a duration of 720 hours 
operating time when burning hazardous waste, the operating requirements 
must be those most likely to ensure compliance with the emission 
standards of Secs. 266.104 through 266.107, based on the Director's 
engineering judgment. If the applicant is seeking a waiver from a trial 
burn to demonstrate conformance with a particular emission standard, the 
operating requirements during this initial period of operation shall 
include those specified by the applicable provisions of Sec. 266.104, 
Sec. 266.105, Sec. 266.106, or Sec. 266.107. The Director may extend the 
duration of this period for up to 720 additional hours when good cause 
for the extension is demonstrated by the applicant.
    (ii) For the duration of the trial burn, the operating requirements 
must be sufficient to demonstrate compliance with the emissions 
standards of Secs. 266.104 through 266.107 and must be in accordance 
with the approved trial burn plan;
    (iii) For the period immediately following completion of the trial 
burn, and only for the minimum period sufficient to allow sample 
analysis, data computation, submission of the trial burn results by the 
applicant, review of the trial burn results and modification of the 
facility permit by the Director to reflect the trial burn results, the 
operating requirements must be those most likely to ensure compliance 
with the emission standards Secs. 266.104 through 266.107 based on the 
Director's engineering judgment.
    (iv) For the remaining duration of the permit, the operating 
requirements must be those demonstrated in a trial burn or by 
alternative data specified in Sec. 270.22 of this chapter, as sufficient 
to ensure compliance with the emissions standards of Secs. 266.104 
through 266.107.
    (e) Operating requirements--(1) General. A boiler or industrial 
furnace burning hazardous waste must be operated in accordance with the 
operating requirements specified in the permit at all times where there 
is hazardous waste in the unit.
    (2) Requirements to ensure compliance with the organic emissions 
standards--(i) DRE standard. Operating conditions will be specified 
either on a case-by-case basis for each hazardous waste burned as those 
demonstrated (in a trial burn or by alternative data as specified in 
Sec. 270.22) to be sufficient to comply with the destruction and removal 
efficiency (DRE) performance standard of Sec. 266.104(a) or as those 
special operating requirements provided by Sec. 266.104(a)(4) for the 
waiver of the DRE trial burn. When the DRE trial burn is not waived 
under Sec. 266.104(a)(4),

[[Page 16]]

each set of operating requirements will specify the composition of the 
hazardous waste (including acceptable variations in the physical and 
chemical properties of the hazardous waste which will not affect 
compliance with the DRE performance standard) to which the operating 
requirements apply. For each such hazardous waste, the permit will 
specify acceptable operating limits including, but not limited to, the 
following conditions as appropriate:
    (A) Feed rate of hazardous waste and other fuels measured and 
specified as prescribed in paragraph (e)(6) of this section;
    (B) Minimum and maximum device production rate when producing normal 
product expressed in appropriate units, measured and specified as

    (G) Such other operating requirements as are necessary to ensure 
that the DRE performance standard of Sec. 266.104(a) is met.
    (ii) Carbon monoxide and hydrocarbon standards. The permit must 
incorporate a carbon monoxide (CO) limit and, as appropriate, a 
hydrocarbon (HC) limit as provided by paragraphs (b), (c), (d), (e) and 
(f) of Sec. 266.104. The permit limits will be specified as follows:
    (A) When complying with the CO standard of Sec. 266.104(b)(1), the 
permit limit is 100 ppmv;
    (B) When complying with the alternative CO standard under 
Sec. 266.104(c), the permit limit for CO is based on the trial burn and 
is established as the average over all valid runs of the highest hourly 
rolling average CO level of each run, and the permit limit for HC is 20 
ppmv (as defined in Sec. 266.104(c)(1)), except as provided in 
Sec. 266.104(f).
    (C) When complying with the alternative HC limit for industrial 
furnaces under Sec. 266.104(f), the permit limit for HC and CO is the 
baseline level when hazardous waste is not burned as specified by that 
paragraph.
    (iii) Start-up and shut-down. During start-up and shut-down of the 
boiler or industrial furnace, hazardous waste (except waste fed solely 
as an ingredient under the Tier I (or adjusted Tier I) feed rate 
screening limits for metals and chloride/chlorine, and except low risk 
waste exempt from the trial burn requirements under Secs. 266.104(a)(5), 
266.105, 266.106, and 266.107) must not be fed into the device unless 
the device is operating within the conditions of operation specified in 
the permit.
    (3) Requirements to ensure conformance with the particulate 
standard. (i) Except as provided in paragraphs (e)(3) (ii) and (iii) of 
this section, the permit shall specify the following operating 
requirements to ensure conformance with the particulate standard 
specified in Sec. 266.105:
    (A) Total ash feed rate to the device from hazardous waste, other 
fuels, and industrial furnace feedstocks, measured and specified as

    (6) Measuring parameters and establishing limits based on trial burn 
data--(i) General requirements. As specified in paragraphs (e)(2) 
through (e)(5) of this section, each operating parameter shall be 
measured, and permit limits on the parameter shall be established, 
according to either of the following procedures:
    (A) Instantaneous limits. A parameter may be measured and recorded 
on an instantaneous basis (i.e., the value that occurs at any time) and 
the permit limit specified as the time-weighted average during all valid 
runs of the trial burn; or
    (B) Hourly rolling average. (1) The limit for a parameter may be 
established and continuously monitored on an hourly rolling average 
basis defined as follows:
    (i) A continuous monitor is one which continuously samples the 
regulated parameter without interruption, and evaluates the detector 
response at least once each 15 seconds, and computes and records the 
average value at least every 60 seconds.
    (ii) An hourly rolling average is the arithmetic mean of the 60 most 
recent 1-minute average values recorded by the continuous monitoring 
system.
    (2) The permit limit for the parameter shall be established based on 
trial burn data as the average over all valid test runs of the highest 
hourly rolling average value for each run.
    (ii) Rolling average limits for carcinogenic metals and lead. Feed 
rate limits for the carcinogenic metals (i.e., arsenic, beryllium, 
cadmium and chromium) and lead may be established either on an hourly 
rolling average basis as prescribed by paragraph (e)(6)(i) of

[[Page 19]]

this section or on (up to) a 24 hour rolling average basis. If the owner 
or operator elects to use an average period from 2 to 24 hours:
    (A) The feed rate of each metal shall be limited at any time to ten 
times the feed rate that would be allowed on an hourly rolling average 
basis;
    (B) The continuous monitor shall meet the following specifications:
    (1) A continuous monitor is one which continuously samples the 
regulated parameter without interruption, and evaluates the detector 
response at least once each 15 seconds, and computes and records the 
average value at least every 60 seconds.
    (2) The rolling average for the selected averaging period is defined 
as the arithmetic mean of one hour block averages for the averaging 
period. A one hour block average is the arithmetic mean of the one 
minute averages recorded during the 60-minute period beginning at one 
minute after the beginning of preceding clock hour; and
    (C) The permit limit for the feed rate of each metal shall be 
established based on trial burn data as the average over all valid test 
runs of the highest hourly rolling average feed rate for each run.
    (iii) Feed rate limits for metals, total chloride and chlorine, and 
ash. Feed rate limits for metals, total chlorine and chloride, and ash 
are established and monitored by knowing the concentration of the 
substance (i.e., metals, chloride/chlorine, and ash) in each feedstream 
and the flow rate of the feedstream. To monitor the feed rate of these 
substances, the flow rate of each feedstream must be monitored under the 
continuous monitoring requirements of paragraphs (e)(6) (i) and (ii) of 
this section.
    (iv) Conduct of trial burn testing. (A) If compliance with all 
applicable emissions standards of Secs. 266.104 through 266.107 is not 
demonstrated simultaneously during a set of test runs, the operating 
conditions of additional test runs required to demonstrate compliance 
with remaining emissions standards must be as close as possible to the 
original operating conditions.
    (B) Prior to obtaining test data for purposes of demonstrating 
compliance with the emissions standards of Secs. 266.104 through 266.107 
or establishing limits on operating parameters under this section, the 
facility must operate under trial burn conditions for a sufficient 
period to reach steady-state operations. The Director may determine, 
however, that industrial furnaces that recycle collected particulate 
matter back into the furnace and that comply with an alternative 
implementation approach for metals under Sec. 266.106(f) need not reach 
steady state conditions with respect to the flow of metals in the system 
prior to beginning compliance testing for metals emissions.
    (C) Trial burn data on the level of an operating parameter for which 
a limit must be established in the permit must be obtained during 
emissions sampling for the pollutant(s) (i.e., metals, PM, HCl/
Cl2, organic compounds) for which the parameter must be 
established as specified by paragraph (e) of this section.
    (7) General requirements--(i) Fugitive emissions. Fugitive emissions 
must be controlled by:
    (A) Keeping the combustion zone totally sealed against fugitive 
emissions; or
    (B) Maintaining the combustion zone pressure lower than atmospheric 
pressure; or
    (C) An alternate means of control demonstrated (with part B of the 
permit application) to provide fugitive emissions control equivalent to 
maintenance of combustion zone pressure lower than atmospheric pressure.
    (ii) Automatic waste feed cutoff. A boiler or industrial furnace 
must be operated with a functioning system that automatically cuts off 
the hazardous waste feed when operating conditions deviate from those 
established under this section. The Director may limit the number of 
cutoffs per an operating period on a case-by-case basis. In addition:
    (A) The permit limit for (the indicator of) minimum combustion 
chamber temperature must be maintained while hazardous waste or 
hazardous waste residues remain in the combustion chamber,
    (B) Exhaust gases must be ducted to the air pollution control system 
operated in accordance with the permit requirements while hazardous 
waste or

[[Page 20]]

hazardous waste residues remain in the combustion chamber; and
    (C) Operating parameters for which permit limits are established 
must continue to be monitored during the cutoff, and the hazardous waste 
feed shall not be restarted until the levels of those parameters comply 
with the permit limits. For parameters that may be monitored on an 
instantaneous basis, the Director will establish a minimum period of 
time after a waste feed cutoff during which the parameter must not 
exceed the permit limit before the hazardous waste feed may be 
restarted.
    (iii) Changes. A boiler or industrial furnace must cease burning 
hazardous waste when changes in combustion properties, or feed rates of 
the hazardous waste, other fuels, or industrial furnace feedstocks, or 
changes in the boiler or industrial furnace design or operating 
conditions deviate from the limits as specified in the permit.
    (8) Monitoring and Inspections. (i) The owner or operator must 
monitor and record the following, at a minimum, while burning hazardous 
waste:
    (A) If specified by the permit, feed rates and composition of 
hazardous waste, other fuels, and industrial furnace feedstocks, and 
feed rates of ash, metals, and total chloride and chlorine;
    (B) If specified by the permit, carbon monoxide (CO), hydrocarbons 
(HC), and oxygen on a continuous basis at a common point in the boiler 
or industrial furnace downstream of the combustion zone and prior to 
release of stack gases to the atmosphere in accordance with operating 
requirements specified in paragraph (e)(2)(ii) of this section. CO, HC, 
and oxygen monitors must be installed, operated, and maintained in 
accordance with methods specified in appendix IX of this part.
    (C) Upon the request of the Director, sampling and analysis of the 
hazardous waste (and other fuels and industrial furnace feedstocks as 
appropriate), residues, and exhaust emissions must be conducted to 
verify that the operating requirements established in the permit achieve 
the applicable standards of Secs. 266.104, 266.105, 266.106, and 
266.107.
    (ii) All monitors shall record data in units corresponding to the 
permit limit unless otherwise specified in the permit.
    (iii) The boiler or industrial furnace and associated equipment 
(pumps, values, pipes, fuel storage tanks, etc.) must be subjected to 
thorough visual inspection when it contains hazardous waste, at least 
daily for leaks, spills, fugitive emissions, and signs of tampering.
    (iv) The automatic hazardous waste feed cutoff system and associated 
alarms must be tested at least once every 7 days when hazardous waste is 
burned to verify operability, unless the applicant demonstrates to the 
Director that weekly inspections will unduly restrict or upset 
operations and that less frequent inspections will be adequate. At a 
minimum, operational testing must be conducted at least once every 30 
days.
    (v) These monitoring and inspection data must be recorded and the 
records must be placed in the operating record required by Sec. 264.73 
of this chapter.
    (9) Direct transfer to the burner. If hazardous waste is directly 
transferred from a transport vehicle to a boiler or industrial furnace 
without the use of a storage unit, the owner and operator must comply 
with Sec. 266.111.
    (10) Recordkeeping. The owner or operator must keep in the operating 
record of the facility all information and data required by this section 
until closure of the facility.
    (11) Closure. At closure, the owner or operator must remove all 
hazardous waste and hazardous waste residues (including, but not limited 
to, ash, scrubber waters, and scrubber sludges) from the boiler or 
industrial furnace.

Sec. 266.103  Interim status standards for burners.

    (a) Purpose, scope, applicability--(1) General. (i) The purpose of 
this section is to establish minimum national standards for owners and 
operators of ``existing'' boilers and industrial furnaces that burn 
hazardous waste where such standards define the acceptable management of 
hazardous waste during the period of interim status. The standards of 
this section apply to owners

[[Page 21]]

and operators of existing facilities until either a permit is issued 
under Sec. 266.102(d) or until closure responsibilities identified in 
this section are fulfilled.
    (ii) Existing or in existence means a boiler or industrial furnace 
that on or before August 21, 1991 is either in operation burning or 
processing hazardous waste or for which construction (including the 
ancillary facilities to burn or to process the hazardous waste) has 
commenced. A facility has commenced construction if the owner or 
operator has obtained the Federal, State, and local approvals or permits 
necessary to begin physical construction; and either:
    (A) A continuous on-site, physical construction program has begun; 
or
    (B) The owner or operator has entered into contractual obligations--
which cannot be canceled or modified without substantial loss--for 
physical construction of the facility to be completed within a 
reasonable time.
    (iii) If a boiler or industrial furnace is located at a facility 
that already has a permit or interim status, then the facility must 
comply with the applicable regulations dealing with permit modifications 
in Sec. 270.42 or changes in interim status in Sec. 270.72 of this 
chapter.
    (2) Exemptions. The requirements of this section do not apply to 
hazardous waste and facilities exempt under Secs. 266.100(b), or 
266.108.
    (3) Prohibition on burning dioxin-listed wastes. The following 
hazardous waste listed for dioxin and hazardous waste derived from any 
of these wastes may not be burned in a boiler or industrial furnace 
operating under interim status: F020, F021, F022, F023, F026, and F027.
    (4) Applicability of part 265 standards. Owners and operators of 
boilers and industrial furnaces that burn hazardous waste and are 
operating under interim status are subject to the following provisions 
of part 265 of this chapter, except as provided otherwise by this 
section:
    (i) In subpart A (General), Sec. 265.4;
    (ii) In subpart B (General facility standards), Secs. 265.11-265.17;
    (iii) In subpart C (Preparedness and prevention), Secs. 265.31-
265.37;
    (iv) In subpart D (Contingency plan and emergency procedures), 
Secs. 265.51-265.56;
    (v) In subpart E (Manifest system, recordkeeping, and reporting), 
Secs. 265.71-265.77, except that Secs. 265.71, 265.72, and 265.76 do not 
apply to owners and operators of on-site facilities that do not receive 
any hazardous waste from off-site sources;
    (vi) In subpart G (Closure and post-closure), Secs. 265.111-265.115;
    (vii) In subpart H (Financial requirements), Secs. 265.141, 265.142, 
265.143, and 265.147-265.151, except that States and the Federal 
government are exempt from the requirements of subpart H; and
    (viii) Subpart BB (Air emission standards for equipment leaks), 
except Sec. 265.1050(a).
    (5) Special requirements for furnaces. The following controls apply 
during interim status to industrial furnaces (e.g., kilns, cupolas) that 
feed hazardous waste for a purpose other than solely as an ingredient 
(see paragraph (a)(5)(ii) of this section) at any location other than 
the hot end where products are normally discharged or where fuels are 
normally fired:
    (i) Controls. (A) The hazardous waste shall be fed at a location 
where combustion gas temperatures are at least 1800 [deg]F;
    (B) The owner or operator must determine that adequate oxygen is 
present in combustion gases to combust organic constituents in the waste 
and retain documentation of such determination in the facility record;
    (C) For cement kiln systems, the hazardous waste shall be fed into 
the kiln; and
    (D) The hydrocarbon controls of Sec. 266.104(c) or paragraph (c)(5) 
of this section apply upon certification of compliance under paragraph 
(c) of this section irrespective of the CO level achieved during the 
compliance test.
    (ii) Burning hazardous waste solely as an ingredient. A hazardous 
waste is burned for a purpose other than solely as an ingredient if it 
meets either of these criteria:
    (A) The hazardous waste has a total concentration of nonmetal 
compounds listed in part 261, appendix VIII, of this chapter exceeding 
500 ppm by weight,

[[Page 22]]

as-fired, and so is considered to be burned for destruction. The 
concentration of nonmetal compounds in a waste as-generated may be 
reduced to the 500 ppm limit by bona fide treatment that removes or 
destroys nonmetal constituents. Blending for dilution to meet the 500 
ppm limit is prohibited and documentation that the waste has not been 
impermissibly diluted must be retained in the facility record; or
    (B) The hazardous waste has a heating value of 5,000 Btu/lb or more, 
as-fired, and so is considered to be burned as fuel. The heating value 
of a waste as-generated may be reduced to below the 5,000 Btu/lb limit 
by bona fide treatment that removes or destroys organic constituents. 
Blending to augment the heating value to meet the 5,000 Btu/lb limit is 
prohibited and documentation that the waste has not been impermissibly 
blended must be retained in the facility record.
    (6) Restrictions on burning hazardous waste that is not a fuel. 
Prior to certification of compliance under paragraph (c) of this 
section, owners and operators shall not feed hazardous waste that has a 
heating value less than 5,000 Btu/lb, as-generated, (except that the 
heating value of a waste as-generated may be increased to above the 
5,000 Btu/lb limit by bona fide treatment; however, blending to augment 
the heating value to meet the 5,000 Btu/lb limit is prohibited and 
records must be kept to document that impermissible blending has not 
occurred) in a boiler or industrial furnace, except that:
    (i) Hazardous waste may be burned solely as an ingredient; or
    (ii) Hazardous waste may be burned for purposes of compliance 
testing (or testing prior to compliance testing) for a total period of 
time not to exceed 720 hours; or
    (iii) Such waste may be burned if the Director has documentation to 
show that, prior to August 21, 1991:
    (A) The boiler or industrial furnace is operating under the interim 
status standards for incinerators provided by subpart O of part 265 of 
this chapter, or the interim status standards for thermal treatment 
units provided by subpart P of part 265 of this chapter; and
    (B) The boiler or industrial furnace met the interim status 
eligibility requirements under Sec. 270.70 of this chapter for subpart O 
or subpart P of part 265 of this chapter; and
    (C) Hazardous waste with a heating value less than 5,000 Btu/lb was 
burned prior to that date; or
    (iv) Such waste may be burned in a halogen acid furnace if the waste 
was burned as an excluded ingredient under Sec. 261.2(e) of this chapter 
prior to February 21, 1991 and documentation is kept on file supporting 
this claim.
    (7) Direct transfer to the burner. If hazardous waste is directly 
transferred from a transport vehicle to a boiler or industrial furnace 
without the use of a storage unit, the owner and operator must comply 
with Sec. 266.111.
    (b) Certification of precompliance--(1) General. The owner or 
operator must provide complete and accurate information specified in 
paragraph (b)(2) of this section to the Director on or before August 21, 
1991, and must establish limits for the operating parameters specified 
in paragraph (b)(3) of this section. Such information is termed a 
``certification of precompliance'' and constitutes a certification that 
the owner or operator has determined that, when the facility is operated 
within the limits specified in paragraph (b)(3) of this section, the 
owner or operator believes that, using best engineering judgment, 
emissions of particulate matter, metals, and HCl and Cl2 are 
not likely to exceed the limits provided by Secs. 266.105, 266.106, and 
266.107. The facility may burn hazardous waste only under the operating 
conditions that the owner or operator establishes under paragraph (b)(3) 
of this section until the owner or operator submits a revised 
certification of precompliance under paragraph (b)(8) of this section or 
a certification of compliance under paragraph (c) of this section, or 
until a permit is issued.
    (2) Information required. The following information must be 
submitted with the certification of precompliance to support the 
determination that the limits established for the operating parameters 
identified in paragraph (b)(3) of this section are not likely to result 
in an exceedance of the allowable emission rates for particulate matter, 
metals, and HCl and Cl2:

operators of furnaces that recycle collected particulate matter (PM) 
back into the furnace and that will certify compliance with the metals 
emissions controls under paragraph (c)(3)(ii)(A) of this section must 
comply with the special operating requirements provided in ``Alternative 
Methodology for Implementing Metals Controls'' in appendix IX of this 
part.
    (5) Measurement of feed rates and production rate--(i) General 
requirements. Limits on each of the parameters specified in paragraph 
(b)(3) of this section (except for limits on metals concentrations in 
collected particulate matter (PM) for industrial furnaces that recycle 
collected PM) shall be established and continuously monitored under 
either of the following methods:
    (A) Instantaneous limits. A limit for a parameter may be established 
and continuously monitored and recorded on an instantaneous basis (i.e., 
the value that occurs at any time) not to be exceeded at any time; or
    (B) Hourly rolling average limits. A limit for a parameter may be 
established and continuously monitored on an hourly rolling average 
basis defined as follows:
    (1) A continuous monitor is one which continuously samples the 
regulated parameter without interruption, and evaluates the detector 
response at least once each 15 seconds, and computes and records the 
average value at least every 60 seconds.
    (2) An hourly rolling average is the arithmetic mean of the 60 most 
recent 1-minute average values recorded by the continuous monitoring 
system.
    (ii) Rolling average limits for carcinogenic metals and lead. Feed 
rate limits for the carcinogenic metals (arsenic, beryllium, cadmium, 
and chromium) and lead may be established either on an hourly rolling 
average basis as prescribed by paragraph (b)(5)(i)(B) or on (up to) a 24 
hour rolling average basis. If the owner or operator elects to use an 
averaging period from 2 to 24 hours:
    (A) The feed rate of each metal shall be limited at any time to ten 
times the feed rate that would be allowed on a hourly rolling average 
basis;
    (B) The continuous monitor shall meet the following specifications:
    (1) A continuous monitor is one which continuously samples the 
regulated parameter without interruption, and evaluates the detector 
response at least once each 15 seconds, and computes and records the 
average value at least every 60 seconds.
    (2) The rolling average for the selected averaging period is defined 
as the arithmetic mean of one hour block averages for the averaging 
period. A one hour block average is the arithmetic mean of the one 
minute averages recorded during the 60-minute period beginning at one 
minute after the beginning of preceding clock hour.
    (iii) Feed rate limits for metals, total chloride and chlorine, and 
ash. Feed rate limits for metals, total chlorine and chloride, and ash 
are established and monitored by knowing the concentration of the 
substance (i.e., metals, chloride/chlorine, and ash) in each feedstream 
and the flow rate of the feedstream. To monitor the feed rate of these 
substances, the flow rate of each feedstream must be monitored under the 
continuous monitoring requirements of paragraphs (b)(5) (i) and (ii) of 
this section.
    (6) Public notice requirements at precompliance. On or before August 
21, 1991 the owner or operator must submit a notice with the following 
information for publication in a major local newspaper of general 
circulation and send a copy of the notice to the appropriate units of 
State and local government. The owner and operator must provide to the 
Director with the certification of precompliance evidence of submitting 
the notice for publication. The notice, which shall be entitled ``Notice 
of Certification of Precompliance with Hazardous Waste Burning 
Requirements of 40 CFR 266.103(b)'', must include:

    (2) Prior notice of compliance testing. At least 30 days prior to 
the compliance testing required by paragraph (c)(3) of this section, the 
owner or operator shall notify the Director and submit the following 
information:
    (i) General facility information including:
    (A) EPA facility ID number;
    (B) Facility name, contact person, telephone number, and address;
    (C) Person responsible for conducting compliance test, including 
company name, address, and telephone number, and a statement of 
qualifications;
    (D) Planned date of the compliance test;
    (ii) Specific information on each device to be tested including:
    (A) Description of boiler or industrial furnace;
    (B) A scaled plot plan showing the entire facility and location of 
the boiler or industrial furnace;
    (C) A description of the air pollution control system;
    (D) Identification of the continuous emission monitors that are 
installed, including:
    (1) Carbon monoxide monitor;
    (2) Oxygen monitor;
    (3) Hydrocarbon monitor, specifying the minimum temperature of the 
system and, if the temperature is less than 150 [deg]C, an explanation 
of why a heated system is not used (see paragraph (c)(5) of this 
section) and a brief description of the sample gas conditioning system;
    (E) Indication of whether the stack is shared with another device 
that will be in operation during the compliance test;
    (F) Other information useful to an understanding of the system 
design or operation.
    (iii) Information on the testing planned, including a complete copy 
of the test protocol and Quality Assurance/Quality Control (QA/QC) plan, 
and a summary description for each test providing the following 
information at a minimum:
    (A) Purpose of the test (e.g., demonstrate compliance with emissions 
of particulate matter); and

[[Page 29]]

    (B) Planned operating conditions, including levels for each 
pertinent parameter specified in paragraph (c)(1) of this section.
    (3) Compliance testing--(i) General. Compliance testing must be 
conducted under conditions for which the owner or operator has submitted 
a certification of precompliance under paragraph (b) of this section and 
under conditions established in the notification of compliance testing 
required by paragraph (c)(2) of this section. The owner or operator may 
seek approval on a case-by-case basis to use compliance test data from 
one unit in lieu of testing a similar onsite unit. To support the 
request, the owner or operator must provide a comparison of the 
hazardous waste burned and other feedstreams, and the design, operation, 
and maintenance of both the tested unit and the similar unit. The 
Director shall provide a written approval to use compliance test data in 
lieu of testing a similar unit if he finds that the hazardous wastes, 
the devices, and the operating conditions are sufficiently similar, and 
the data from the other compliance test is adequate to meet the 
requirements of Sec. 266.103(c).
    (ii) Special requirements for industrial furnaces that recycle 
collected PM. Owners and operators of industrial furnaces that recycle 
back into the furnace particulate matter (PM) from the air pollution 
control system must comply with one of the following procedures for 
testing to determine compliance with the metals standards of 
Sec. 266.106(c) or (d):
    (A) The special testing requirements prescribed in ``Alternative 
Method for Implementing Metals Controls'' in appendix IX of this part; 
or
    (B) Stack emissions testing for a minimum of 6 hours each day while 
hazardous waste is burned during interim status. The testing must be 
conducted when burning normal hazardous waste for that day at normal 
feed rates for that day and when the air pollution control system is 
operated under normal conditions. During interim status, hazardous waste 
analysis for metals content must be sufficient for the owner or operator 
to determine if changes in metals content may affect the ability of the 
facility to meet the metals emissions standards established under 
Sec. 266.106(c) or (d). Under this option, operating limits (under 
paragraph (c)(1) of this section) must be established during compliance 
testing under paragraph (c)(3) of this section only on the following 
parameters;
    (1) Feed rate of total hazardous waste;
    (2) Total feed rate of chlorine and chloride in total feed streams;
    (3) Total feed rate of ash in total feed streams, except that the 
ash feed rate for cement kilns and light-weight aggregate kilns is not 
limited;
    (4) Carbon monoxide concentration, and where required, hydrocarbon 
concentration in stack gas;
    (5) Maximum production rate of the device in appropriate units when 
producing normal product; or
    (C) Conduct compliance testing to determine compliance with the 
metals standards to establish limits on the operating parameters of 
paragraph (c)(1) of this section only after the kiln system has been 
conditioned to enable it to reach equilibrium with respect to metals fed 
into the system and metals emissions. During conditioning, hazardous 
waste and raw materials having the same metals content as will be fed 
during the compliance test must be fed at the feed rates that will be 
fed during the compliance test.
    (iii) Conduct of compliance testing. (A) If compliance with all 
applicable emissions standards of Secs. 266.104 through 266.107 is not 
demonstrated simultaneously during a set of test runs, the operating 
conditions of additional test runs required to demonstrate compliance 
with remaining emissions standards must be as close as possible to the 
original operating conditions.
    (B) Prior to obtaining test data for purposes of demonstrating 
compliance with the applicable emissions standards of Secs. 266.104 
through 266.107 or establishing limits on operating parameters under 
this section, the facility must operate under compliance test conditions 
for a sufficient period to reach steady-state operations. Industrial 
furnaces that recycle collected particulate matter back into the furnace 
and that comply with paragraphs

[[Page 30]]

(c)(3)(ii)(A) or (B) of this section, however, need not reach steady 
state conditions with respect to the flow of metals in the system prior 
to beginning compliance testing for metals.
    (C) Compliance test data on the level of an operating parameter for 
which a limit must be established in the certification of compliance 
must be obtained during emissions sampling for the pollutant(s) (i.e., 
metals, PM, HCl/Cl2, organic compounds) for which the 
parameter must be established as specified by paragraph (c)(1) of this 
section.
    (4) Certification of compliance. Within 90 days of completing 
compliance testing, the owner or operator must certify to the Director 
compliance with the emissions standards of Secs. 266.104 (b), (c), and 
(e), 266.105, 266.106, 266.107, and paragraph (a)(5)(i)(D) of this 
section. The certification of compliance must include the following 
information:
    (i) General facility and testing information including:
    (A) EPA facility ID number;
    (B) Facility name, contact person, telephone number, and address;
    (C) Person responsible for conducting compliance testing, including 
company name, address, and telephone number, and a statement of 
qualifications;
    (D) Date(s) of each compliance test;
    (E) Description of boiler or industrial furnace tested;
    (F) Person responsible for quality assurance/quality control (QA/
QC), title, and telephone number, and statement that procedures 
prescribed in the QA/QC plan submitted under Sec. 266.103(c)(2)(iii) 
have been followed, or a description of any changes and an explanation 
of why changes were necessary.
    (G) Description of any changes in the unit configuration prior to or 
during testing that would alter any of the information submitted in the 
prior notice of compliance testing under paragraph (c)(2) of this 
section, and an explanation of why the changes were necessary;
    (H) Description of any changes in the planned test conditions prior 
to or during the testing that alter any of the information submitted in 
the prior notice of compliance testing under paragraph (c)(2) of this 
section, and an explanation of why the changes were necessary; and
    (I) The complete report on results of emissions testing.
    (ii) Specific information on each test including:
    (A) Purpose(s) of test (e.g., demonstrate conformance with the 
emissions limits for particulate matter, metals, HCl, Cl2, 
and CO)
    (B) Summary of test results for each run and for each test including 
the following information:
    (1) Date of run;
    (2) Duration of run;
    (3) Time-weighted average and highest hourly rolling average CO 
level for each run and for the test;
    (4) Highest hourly rolling average HC level, if HC monitoring is 
required for each run and for the test;
    (5) If dioxin and furan testing is required under Sec. 266.104(e), 
time-weighted average emissions for each run and for the test of 
chlorinated dioxin and furan emissions, and the predicted maximum annual 
average ground level concentration of the toxicity equivalency factor;
    (6) Time-weighted average particulate matter emissions for each run 
and for the test;
    (7) Time-weighted average HCl and Cl2 emissions for each 
run and for the test;
    (8) Time-weighted average emissions for the metals subject to 
regulation under Sec. 266.106 for each run and for the test; and
    (9) QA/QC results.
    (iii) Comparison of the actual emissions during each test with the 
emissions limits prescribed by Secs. 266.104 (b), (c), and (e), 266.105, 
266.106, and 266.107 and established for the facility in the 
certification of precompliance under paragraph (b) of this section.
    (iv) Determination of operating limits based on all valid runs of 
the compliance test for each applicable parameter listed in paragraph 
(c)(1) of this section using either of the following procedures:
    (A) Instantaneous limits. A parameter may be measured and recorded 
on an instantaneous basis (i.e., the value that occurs at any time) and 
the operating limit specified as the time-weighted average during all 
runs of the compliance test; or

[[Page 31]]

    (B) Hourly rolling average basis. (1) The limit for a parameter may 
be established and continuously monitored on an hourly rolling average 
basis defined as follows:
    (i) A continuous monitor is one which continuously samples the 
regulated parameter without interruption, and evaluates the detector 
response at least once each 15 seconds, and computes and records the 
average value at least every 60 seconds.
    (ii) An hourly rolling average is the arithmetic mean of the 60 most 
recent 1-minute average values recorded by the continuous monitoring 
system.
    (2) The operating limit for the parameter shall be established based 
on compliance test data as the average over all test runs of the highest 
hourly rolling average value for each run.
    (C) Rolling average limits for carcinogenic metals and lead. Feed 
rate limits for the carcinogenic metals (i.e., arsenic, beryllium, 
cadmium and chromium) and lead may be established either on an hourly 
rolling average basis as prescribed by paragraph (c)(4)(iv)(B) of this 
section or on (up to) a 24 hour rolling average basis. If the owner or 
operator elects to use an averaging period from 2 to 24 hours:
    (1) The feed rate of each metal shall be limited at any time to ten 
times the feed rate that would be allowed on a hourly rolling average 
basis;
    (2) The continuous monitor shall meet the following specifications:
    (i) A continuous monitor is one which continuously samples the 
regulated parameter without interruption, and evaluates the detector 
response at least once each 15 seconds, and computes and records the 
average value at least every 60 seconds.
    (ii) The rolling average for the selected averaging period is 
defined as arithmetic mean of one hour block averages for the averaging 
period. A one hour block average is the arithmetic mean of the one 
minute averages recorded during the 60-minute period beginning at one 
minute after the beginning of preceding clock hour; and
    (3) The operating limit for the feed rate of each metal shall be 
established based on compliance test data as the average over all test 
runs of the highest hourly rolling average feed rate for each run.
    (D) Feed rate limits for metals, total chloride and chlorine, and 
ash. Feed rate limits for metals, total chlorine and chloride, and ash 
are established and monitored by knowing the concentration of the 
substance (i.e., metals, chloride/chlorine, and ash) in each feedstream 
and the flow rate of the feedstream. To monitor the feed rate of these 
substances, the flow rate of each feedstream must be monitored under the 
continuous monitoring requirements of paragraphs (c)(4)(iv) (A) through 
(C) of this section.
    (v) Certification of compliance statement. The following statement 
shall accompany the certification of compliance:

    ``I certify under penalty of law that this information was prepared 
under my direction or supervision in accordance with a system designed 
to ensure that qualified personnel properly gathered and evaluated the 
information and supporting documentation. Copies of all emissions tests, 
dispersion modeling results and other information used to determine 
conformance with the requirements of Sec. 266.103(c) are available at 
the facility and can be obtained from the facility contact person listed 
above. Based on my inquiry of the person or persons who manages the 
facility, or those persons directly responsible for gathering the 
information, the information submitted is, to the best of my knowledge 
and belief, true, accurate, and complete. I am aware that there are 
significant penalties for submitting false information, including the 
possibility of fine and imprisonment for knowing violations.
    I also acknowledge that the operating conditions established in this 
certification pursuant to Sec. 266.103(c)(4)(iv) are enforceable limits 
at which the facility can legally operate during interim status until a 
revised certification of compliance is submitted.''

    (5) Special requirements for HC monitoring systems. When an owner or 
operator is required to comply with the hydrocarbon (HC) controls 
provided by Sec. 266.104(c) or paragraph (a)(5)(i)(D) of this section, a 
conditioned gas monitoring system may be used in conformance with 
specifications provided in appendix IX of this part provided that the 
owner or operator submits a certification of compliance without using 
extensions of time provided by paragraph (c)(7) of this section.

[[Page 32]]

    (6) Special operating requirements for industrial furnaces that 
recycle collected PM. Owners and operators of industrial furnaces that 
recycle back into the furnace particulate matter (PM) from the air 
pollution control system must:
    (i) When complying with the requirements of paragraph (c)(3)(ii)(A) 
of this section, comply with the operating requirements prescribed in 
``Alternative Method to Implement the Metals Controls'' in appendix IX 
of this part; and
    (ii) When complying with the requirements of paragraph (c)(3)(ii)(B) 
of this section, comply with the operating requirements prescribed by 
that paragraph.
    (7) Extensions of time. (i) If the owner or operator does not submit 
a complete certification of compliance for all of the applicable 
emissions standards of Secs. 266.104, 266.105, 266.106, and 266.107 by 
August 21, 1992, he/she must either:
    (A) Stop burning hazardous waste and begin closure activities under 
paragraph (l) of this section for the hazardous waste portion of the 
facility; or
    (B) Limit hazardous waste burning only for purposes of compliance 
testing (and pretesting to prepare for compliance testing) a total 
period of 720 hours for the period of time beginning August 21, 1992, 
submit a notification to the Director by August 21, 1992 stating that 
the facility is operating under restricted interim status and intends to 
resume burning hazardous waste, and submit a complete certification of 
compliance by August 23, 1993; or
    (C) Obtain a case-by-case extension of time under paragraph 
(c)(7)(ii) of this section.
    (ii) The owner or operator may request a case-by-case extension of 
time to extend any time limit provided by paragraph (c) of this section 
if compliance with the time limit is not practicable for reasons beyond 
the control of the owner or operator.
    (A) In granting an extension, the Director may apply conditions as 
the facts warrant to ensure timely compliance with the requirements of 
this section and that the facility operates in a manner that does not 
pose a hazard to human health and the environment;
    (B) When an owner or operator requests an extension of time to 
enable the facility to comply with the alternative hydrocarbon 
provisions of Sec. 266.104(f) and obtain a RCRA operating permit because 
the facility cannot meet the HC limit of Sec. 266.104(c) of this 
chapter:
    (1) The Director shall, in considering whether to grant the 
extension:
    (i) Determine whether the owner and operator have submitted in a 
timely manner a complete part B permit application that includes 
information required under Sec. 270.22(b) of this chapter; and
    (ii) Consider whether the owner and operator have made a good faith 
effort to certify compliance with all other emission controls, including 
the controls on dioxins and furans of Sec. 266.104(e) and the controls 
on PM, metals, and HCl/Cl2.
    (2) If an extension is granted, the Director shall, as a condition 
of the extension, require the facility to operate under flue gas 
concentration limits on CO and HC that, based on available information, 
including information in the part B permit application, are baseline CO 
and HC levels as defined by Sec. 266.104(f)(1).
    (8) Revised certification of compliance. The owner or operator may 
submit at any time a revised certification of compliance 
(recertification of compliance) under the following procedures:
    (i) Prior to submittal of a revised certification of compliance, 
hazardous waste may not be burned for more than a total of 720 hours 
under operating conditions that exceed those established under a current 
certification of compliance, and such burning may be conducted only for 
purposes of determining whether the facility can operate under revised 
conditions and continue to meet the applicable emissions standards of 
Secs. 266.104, 266.105, 266.106, and 266.107;
    (ii) At least 30 days prior to first burning hazardous waste under 
operating conditions that exceed those established under a current 
certification of compliance, the owner or operator shall notify the 
Director and submit the following information:
    (A) EPA facility ID number, and facility name, contact person, 
telephone number, and address;
    (B) Operating conditions that the owner or operator is seeking to 
revise

[[Page 33]]

and description of the changes in facility design or operation that 
prompted the need to seek to revise the operating conditions;
    (C) A determination that when operating under the revised operating 
conditions, the applicable emissions standards of Secs. 266.104, 
266.105, 266.106, and 266.107 are not likely to be exceeded. To document 
this determination, the owner or operator shall submit the applicable 
information required under paragraph (b)(2) of this section; and
    (D) Complete emissions testing protocol for any pretesting and for a 
new compliance test to determine compliance with the applicable 
emissions standards of Secs. 266.104, 266.105, 266.106, and 266.107 when 
operating under revised operating conditions. The protocol shall include 
a schedule of pre-testing and compliance testing. If the owner and 
operator revises the scheduled date for the compliance test, he/she 
shall notify the Director in writing at least 30 days prior to the 
revised date of the compliance test;
    (iii) Conduct a compliance test under the revised operating 
conditions and the protocol submitted to the Director to determine 
compliance with the applicable emissions standards of Secs. 266.104, 
266.105, 266.106, and 266.107; and
    (iv) Submit a revised certification of compliance under paragraph 
(c)(4) of this section.
    (d) Periodic Recertifications. The owner or operator must conduct 
compliance testing and submit to the Director a recertification of 
compliance under provisions of paragraph (c) of this section within 
three years from submitting the previous certification or 
recertification. If the owner or operator seeks to recertify compliance 
under new operating conditions, he/she must comply with the requirements 
of paragraph (c)(8) of this section.
    (e) Noncompliance with certification schedule. If the owner or 
operator does not comply with the interim status compliance schedule 
provided by paragraphs (b), (c), and (d) of this section, hazardous 
waste burning must terminate on the date that the deadline is missed, 
closure activities must begin under paragraph (l) of this section, and 
hazardous waste burning may not resume except under an operating permit 
issued under Sec. 270.66 of this chapter. For purposes of compliance 
with the closure provisions of paragraph (l) of this section and 
Secs. 265.112(d)(2) and 265.113 of this chapter the boiler or industrial 
furnace has received ``the known final volume of hazardous waste'' on 
the date that the deadline is missed.
    (f) Start-up and shut-down. Hazardous waste (except waste fed solely 
as an ingredient under the Tier I (or adjusted Tier I) feed rate 
screening limits for metals and chloride/chlorine) must not be fed into 
the device during start-up and shut-down of the boiler or industrial 
furnace, unless the device is operating within the conditions of 
operation specified in the certification of compliance.
    (g) Automatic waste feed cutoff. During the compliance test required 
by paragraph (c)(3) of this section, and upon certification of 
compliance under paragraph (c) of this section, a boiler or industrial 
furnace must be operated with a functioning system that automatically 
cuts off the hazardous waste feed when the applicable operating 
conditions specified in paragraphs (c)(1) (i) and (v through xiii) of 
this section deviate from those established in the certification of 
compliance. In addition:
    (1) To minimize emissions of organic compounds, the minimum 
combustion chamber temperature (or the indicator of combustion chamber 
temperature) that occurred during the compliance test must be maintained 
while hazardous waste or hazardous waste residues remain in the 
combustion chamber, with the minimum temperature during the compliance 
test defined as either:
    (i) If compliance with the combustion chamber temperature limit is 
based on a hourly rolling average, the minimum temperature during the 
compliance test is considered to be the average over all runs of the 
lowest hourly rolling average for each run; or
    (ii) If compliance with the combustion chamber temperature limit is 
based on an instantaneous temperature measurement, the minimum 
temperature during the compliance test is considered to be the time-
weighted average temperature during all runs of the test; and

[[Page 34]]

    (2) Operating parameters limited by the certification of compliance 
must continue to be monitored during the cutoff, and the hazardous waste 
feed shall not be restarted until the levels of those parameters comply 
with the limits established in the certification of compliance.
    (h) Fugitive emissions. Fugitive emissions must be controlled by:
    (1) Keeping the combustion zone totally sealed against fugitive 
emissions; or
    (2) Maintaining the combustion zone pressure lower than atmospheric 
pressure; or
    (3) An alternate means of control that the owner or operator can 
demonstrate provide fugitive emissions control equivalent to maintenance 
of combustion zone pressure lower than atmospheric pressure. Support for 
such demonstration shall be included in the operating record.
    (i) Changes. A boiler or industrial furnace must cease burning 
hazardous waste when changes in combustion properties, or feed rates of 
the hazardous waste, other fuels, or industrial furnace feedstocks, or 
changes in the boiler or industrial furnace design or operating 
conditions deviate from the limits specified in the certification of 
compliance.
    (j) Monitoring and Inspections. (1) The owner or operator must 
monitor and record the following, at a minimum, while burning hazardous 
waste:
    (i) Feed rates and composition of hazardous waste, other fuels, and 
industrial furnace feed stocks, and feed rates of ash, metals, and total 
chloride and chlorine as necessary to ensure conformance with the 
certification of precompliance or certification of compliance;
    (ii) Carbon monoxide (CO), oxygen, and if applicable, hydrocarbons 
(HC), on a continuous basis at a common point in the boiler or 
industrial furnace downstream of the combustion zone and prior to 
release of stack gases to the atmosphere in accordance with the 
operating limits specified in the certification of compliance. CO, HC, 
and oxygen monitors must be installed, operated, and maintained in 
accordance with methods specified in appendix IX of this part.
    (iii) Upon the request of the Director, sampling and analysis of the 
hazardous waste (and other fuels and industrial furnace feed stocks as 
appropriate) and the stack gas emissions must be conducted to verify 
that the operating conditions established in the certification of 
precompliance or certification of compliance achieve the applicable 
standards of Secs. 266.104, 266.105, 266.106, and 266.107.
    (2) The boiler or industrial furnace and associated equipment 
(pumps, valves, pipes, fuel storage tanks, etc.) must be subjected to 
thorough visual inspection when they contain hazardous waste, at least 
daily for leaks, spills, fugitive emissions, and signs of tampering.
    (3) The automatic hazardous waste feed cutoff system and associated 
alarms must be tested at least once every 7 days when hazardous waste is 
burned to verify operability, unless the owner or operator can 
demonstrate that weekly inspections will unduly restrict or upset 
operations and that less frequent inspections will be adequate. Support 
for such demonstration shall be included in the operating record. At a 
minimum, operational testing must be conducted at least once every 30 
days.
    (4) These monitoring and inspection data must be recorded and the 
records must be placed in the operating log.
    (k) Recordkeeping. The owner or operator must keep in the operating 
record of the facility all information and data required by this section 
until closure of the boiler or industrial furnace unit.
    (l) Closure. At closure, the owner or operator must remove all 
hazardous waste and hazardous waste residues (including, but not limited 
to, ash, scrubber waters, and scrubber sludges) from the boiler or 
industrial furnace and must comply with Secs. 265.111-265.115 of this 
chapter.

Sec. 266.104  Standards to control organic emissions.

    (a) DRE standard--(1) General. Except as provided in paragraph 
(a)(3) of this section, a boiler or industrial furnace

[[Page 35]]

burning hazardous waste must achieve a destruction and removal 
efficiency (DRE) of 99.99% for all organic hazardous constituents in the 
waste feed. To demonstrate conformance with this requirement, 99.99% DRE 
must be demonstrated during a trial burn for each principal organic 
hazardous constituent (POHC) designated (under paragraph (a)(2) of this 
section) in its permit for each waste feed. DRE is determined for each 
POHC from the following equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.000

where:

    Win= Mass feed rate of one principal organic hazardous 
constituent (POHC) in the hazardous waste fired to the boiler or 
industrial furnace; and
    Wout= Mass emission rate of the same POHC present in 
stack gas prior to release to the atmosphere.

    (2) Designation of POHCs. Principal organic hazardous constituents 
(POHCs) are those compounds for which compliance with the DRE 
requirements of this section shall be demonstrated in a trial burn in 
conformance with procedures prescribed in Sec. 270.66 of this chapter. 
One or more POHCs shall be designated by the Director for each waste 
feed to be burned. POHCs shall be designated based on the degree of 
difficulty of destruction of the organic constituents in the waste and 
on their concentrations or mass in the waste feed considering the 
results of waste analyses submitted with part B of the permit 
application. POHCs are most likely to be selected from among those 
compounds listed in part 261, appendix VIII of this chapter that are 
also present in the normal waste feed. However, if the applicant 
demonstrates to the Regional Administrator's satisfaction that a 
compound not listed in appendix VIII or not present in the normal waste 
feed is a suitable indicator of compliance with the DRE requirements of 
this section, that compound may be designated as a POHC. Such POHCs need 
not be toxic or organic compounds.
    (3) Dioxin-listed waste. A boiler or industrial furnace burning 
hazardous waste containing (or derived from) EPA Hazardous Wastes Nos. 
F020, F021, F022, F023, F026, or F027 must achieve a destruction and 
removal efficiency (DRE) of 99.9999% for each POHC designated (under 
paragraph (a)(2) of this section) in its permit. This performance must 
be demonstrated on POHCs that are more difficult to burn than tetra-, 
penta-, and hexachlorodibenzo-p-dioxins and dibenzofurans. DRE is 
determined for each POHC from the equation in paragraph (a)(1) of this 
section. In addition, the owner or operator of the boiler or industrial 
furnace must notify the Director of intent to burn EPA Hazardous Waste 
Nos. F020, F021, F022, F023, F026, or F027.
    (4) Automatic waiver of DRE trial burn. Owners and operators of 
boilers operated under the special operating requirements provided by 
Sec. 266.110 are considered to be in compliance with the DRE standard of 
paragraph (a)(1) of this section and are exempt from the DRE trial burn.
    (5) Low risk waste. Owners and operators of boilers or industrial 
furnaces that burn hazardous waste in compliance with the requirements 
of Sec. 266.109(a) are considered to be in compliance with the DRE 
standard of paragraph (a)(1) of this section and are exempt from the DRE 
trial burn.
    (b) Carbon monoxide standard. (1) Except as provided in paragraph 
(c) of this section, the stack gas concentration of carbon monoxide (CO) 
from a boiler or industrial furnace burning hazardous waste cannot 
exceed 100 ppmv on an hourly rolling average basis (i.e., over any 60 
minute period), continuously corrected to 7 percent oxygen, dry gas 
basis.
    (2) CO and oxygen shall be continuously monitored in conformance 
with ``Performance Specifications for Continuous Emission Monitoring of 
Carbon Monoxide and Oxygen for Incinerators, Boilers, and Industrial 
Furnaces Burning Hazardous Waste'' in appendix IX of this part.
    (3) Compliance with the 100 ppmv CO limit must be demonstrated 
during the

[[Page 36]]

trial burn (for new facilities or an interim status facility applying 
for a permit) or the compliance test (for interim status facilities). To 
demonstrate compliance, the highest hourly rolling average CO level 
during any valid run of the trial burn or compliance test must not 
exceed 100 ppmv.
    (c) Alternative carbon monoxide standard. (1) The stack gas 
concentration of carbon monoxide (CO) from a boiler or industrial 
furnace burning hazardous waste may exceed the 100 ppmv limit provided 
that stack gas concentrations of hydrocarbons (HC) do not exceed 20 
ppmv, except as provided by paragraph (f) of this section for certain 
industrial furnaces.
    (2) HC limits must be established under this section on an hourly 
rolling average basis (i.e., over any 60 minute period), reported as 
propane, and continuously corrected to 7 percent oxygen, dry gas basis.
    (3) HC shall be continuously monitored in conformance with 
``Performance Specifications for Continuous Emission Monitoring of 
Hydrocarbons for Incinerators, Boilers, and Industrial Furnaces Burning 
Hazardous Waste'' in appendix IX of this part. CO and oxygen shall be 
continuously monitored in conformance with paragraph (b)(2) of this 
section.
    (4) The alternative CO standard is established based on CO data 
during the trial burn (for a new facility) and the compliance test (for 
an interim status facility). The alternative CO standard is the average 
over all valid runs of the highest hourly average CO level for each run. 
The CO limit is implemented on an hourly rolling average basis, and 
continuously corrected to 7 percent oxygen, dry gas basis.
    (d) Special requirements for furnaces. Owners and operators of 
industrial furnaces (e.g., kilns, cupolas) that feed hazardous waste for 
a purpose other than solely as an ingredient (see 
Sec. 266.103(a)(5)(ii)) at any location other than the end where 
products are normally discharged and where fuels are normally fired must 
comply with the hydrocarbon limits provided by paragraphs (c) or (f) of 
this section irrespective of whether stack gas CO concentrations meet 
the 100 ppmv limit of paragraph (b) of this section.
    (e) Controls for dioxins and furans. Owners and operators of boilers 
and industrial furnaces that are equipped with a dry particulate matter 
control device that operates within the temperature range of 450-750 
[deg]F, and industrial furnaces operating under an alternative 
hydrocarbon limit established under paragraph (f) of this section must 
conduct a site-specific risk assessment as follows to demonstrate that 
emissions of chlorinated dibenzo-p-dioxins and dibenzofurans do not 
result in an increased lifetime cancer risk to the hypothetical maximum 
exposed individual (MEI) exceeding 1 in 100,000:
    (1) During the trial burn (for new facilities or an interim status 
facility applying for a permit) or compliance test (for interim status 
facilities), determine emission rates of the tetra-octa congeners of 
chlorinated dibenzo-p-dioxins and dibenzofurans (CDDs/CDFs) using Method 
0023A, Sampling Method for Polychlorinated Dibenzo-p-Dioxins and 
Polychlorinated Dibenzofurans Emissions from Stationary Sources, EPA 
Publication SW-846, as incorporated by reference in Sec. 260.11 of this 
chapter.
    (2) Estimate the 2,3,7,8-TCDD toxicity equivalence of the tetra-octa 
CDDs/CDFs congeners using ``Procedures for Estimating the Toxicity 
Equivalence of Chlorinated Dibenzo-p-Dioxin and Dibenzofuran Congeners'' 
in appendix IX of this part. Multiply the emission rates of CDD/CDF 
congeners with a toxicity equivalence greater than zero (see the 
procedure) by the calculated toxicity equivalence factor to estimate the 
equivalent emission rate of 2,3,7,8-TCDD;
    (3) Conduct dispersion modeling using methods recommended in 
appendix W of part 51 of this chapter (``Guideline on Air Quality Models 
(Revised)'' (1986) and its supplements), the ``Hazardous Waste 
Combustion Air Quality Screening Procedure'', provided in appendix IX of 
this part, or in Screening Procedures for Estimating the Air Quality 
Impact of Stationary Sources, Revised (incorporated by reference in 
Sec. 260.11) to predict the maximum annual average off-site ground level 
concentration of 2,3,7,8-TCDD

[[Page 37]]

equivalents determined under paragraph (e)(2) of this section. The 
maximum annual average concentration must be used when a person resides 
on-site; and
    (4) The ratio of the predicted maximum annual average ground level 
concentration of 2,3,7,8-TCDD equivalents to the risk-specific dose for 
2,3,7,8-TCDD provided in appendix V of this part (2.2 X 10-
[hyphen]7) shall not exceed 1.0.
    (f) Monitoring CO and HC in the by-pass duct of a cement kiln. 
Cement kilns may comply with the carbon monoxide and hydrocarbon limits 
provided by paragraphs (b), (c), and (d) of this section by monitoring 
in the by-pass duct provided that:
    (1) Hazardous waste is fired only into the kiln and not at any 
location downstream from the kiln exit relative to the direction of gas 
flow; and
    (2) The by-pass duct diverts a minimum of 10% of kiln off-gas into 
the duct.
    (g) Use of emissions test data to demonstrate compliance and 
establish operating limits. Compliance with the requirements of this 
section must be demonstrated simultaneously by emissions testing or 
during separate runs under identical operating conditions. Further, data 
to demonstrate compliance with the CO and HC limits of this section or 
to establish alternative CO or HC limits under this section must be 
obtained during the time that DRE testing, and where applicable, CDD/CDF 
testing under paragraph (e) of this section and comprehensive organic 
emissions testing under paragraph (f) is conducted.
    (h) Enforcement. For the purposes of permit enforcement, compliance 
with the operating requirements specified in the permit (under 
Sec. 266.102) will be regarded as compliance with this section. However, 
evidence that compliance with those permit conditions is insufficient to 
ensure compliance with the requirements of this section may be 
``information'' justifying modification or revocation and re-issuance of 
a permit under Sec. 270.41 of this chapter.

[56 FR 7208, Feb. 21, 1991; 56 FR 32689, July 17, 1991, as amended at 57 
FR 38565, Aug. 25, 1992; 58 FR 38883, July 20, 1993; 60 FR 33914, June 
29, 1995; 62 FR 32463, June 13, 1997]



Sec. 266.105  Standards to control particulate matter.

    (a) A boiler or industrial furnace burning hazardous waste may not 
emit particulate matter in excess of 180 milligrams per dry standard 
cubic meter (0.08 grains per dry standard cubic foot) after correction 
to a stack gas concentration of 7% oxygen, using procedures prescribed 
in 40 CFR part 60, appendix A, methods 1 through 5, and appendix IX of 
this part.
    (b) An owner or operator meeting the requirements of Sec. 266.109(b) 
for the low risk waste exemption is exempt from the particulate matter 
standard.
    (c) Oxygen correction. (1) Measured pollutant levels must be 
corrected for the amount of oxygen in the stack gas according to the 
formula:
[GRAPHIC] [TIFF OMITTED] TR30SE99.027

Where:
Pc is the corrected concentration of the pollutant in the stack gas, Pm 
    is the measured concentration of the pollutant in the stack gas, E 
    is the oxygen concentration on a dry basis in the combustion air fed 
    to the device, and Y is the measured oxygen concentration on a dry 
    basis in the stack.

    (2) For devices that feed normal combustion air, E will equal 21 
percent. For devices that feed oxygen-enriched air for combustion (that 
is, air with an oxygen concentration exceeding 21 percent), the value of 
E will be the concentration of oxygen in the enriched air.
    (3) Compliance with all emission standards provided by this subpart 
must be based on correcting to 7 percent oxygen using this procedure.
    (d) For the purposes of permit enforcement, compliance with the 
operating requirements specified in the permit (under Sec. 266.102) will 
be regarded as compliance with this section. However, evidence that 
compliance with those permit conditions is insufficient to ensure 
compliance with the requirements of this section may be ``information'' 
justifying modification or revocation and re-issuance of a permit under 
Sec. 270.41 of this chapter.

Sec. 266.106  Standards to control metals emissions.

    (a) General. The owner or operator must comply with the metals 
standards provided by paragraphs (b), (c), (d), (e), or (f) of this 
section for each metal listed in paragraph (b) of this section that is 
present in the hazardous waste at detectable levels using analytical 
procedures specified in Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods (SW-846), incorporated by reference in 
Sec. 260.11 of this chapter.
    (b) Tier I feed rate screening limits. Feed rate screening limits 
for metals are specified in appendix I of this part as a function of 
terrain-adjusted effective stack height and terrain and land use in the 
vicinity of the facility. Criteria for facilities that are not eligible 
to comply with the screening limits are provided in paragraph (b)(7) of 
this section.
    (1) Noncarcinogenic metals. The feed rates of antimony, barium, 
lead, mercury, thallium, and silver in all feed streams, including 
hazardous waste, fuels, and industrial furnace feed stocks shall not 
exceed the screening limits specified in appendix I of this part.
    (i) The feed rate screening limits for antimony, barium, mercury, 
thallium, and silver are based on either:
    (A) An hourly rolling average as defined in 
Sec. 266.102(e)(6)(i)(B); or
    (B) An instantaneous limit not to be exceeded at any time.
    (ii) The feed rate screening limit for lead is based on one of the 
following:
    (A) An hourly rolling average as defined in 
Sec. 266.102(e)(6)(i)(B);
    (B) An averaging period of 2 to 24 hours as defined in 
Sec. 266.102(e)(6)(ii) with an instantaneous feed rate limit not to 
exceed 10 times the feed rate that would be allowed on an hourly rolling 
average basis; or
    (C) An instantaneous limit not to be exceeded at any time.
    (2) Carcinogenic metals. (i) The feed rates of arsenic, cadmium, 
beryllium, and chromium in all feed streams, including hazardous waste, 
fuels, and industrial furnace feed stocks shall not exceed values 
derived from the screening limits specified in appendix I of this part. 
The feed rate of each of these metals is limited to a level such that 
the sum of the ratios of the actual feed rate to the feed rate screening 
limit specified in appendix I shall not exceed 1.0, as provided by the 
following equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.001


where:
    n=number of carcinogenic metals
    AFR=actual feed rate to the device for metal ``i''
    FRSL=feed rate screening limit provided by appendix I of this part 
for metal ``i''.

    (ii) The feed rate screening limits for the carcinogenic metals are 
based on either:
    (A) An hourly rolling average; or
    (B) An averaging period of 2 to 24 hours as defined in 
Sec. 266.102(e)(6)(ii) with an instantaneous feed rate limit not to 
exceed 10 times the feed rate that would be allowed on an hourly rolling 
average basis.
    (3) TESH. (i) The terrain-adjusted effective stack height is 
determined according to the following equation:

TESH=Ha+H1-Tr

where:
    Ha=Actual physical stack height
    H1=Plume rise as determined from appendix VI of this part as a 
function of stack flow rate and stack gas exhaust temperature.
    Tr=Terrain rise within five kilometers of the stack.

    (ii) The stack height (Ha) may not exceed good engineering practice 
as specified in 40 CFR 51.100(ii).
    (iii) If the TESH for a particular facility is not listed in the 
table in the appendices, the nearest lower TESH listed in the table 
shall be used. If the TESH is four meters or less, a value of four 
meters shall be used.
    (4) Terrain type. The screening limits are a function of whether the 
facility is located in noncomplex or complex terrain. A device located 
where any part of the surrounding terrain within 5 kilometers of the 
stack equals or exceeds the elevation of the physical stack height (Ha) 
is considered to be in complex terrain and the screening limits for 
complex terrain apply. Terrain measurements are to be made from

[[Page 39]]

U.S. Geological Survey 7.5-minute topographic maps of the area 
surrounding the facility.
    (5) Land use. The screening limits are a function of whether the 
facility is located in an area where the land use is urban or rural. To 
determine whether land use in the vicinity of the facility is urban or 
rural, procedures provided in appendices IX or X of this part shall be 
used.
    (6) Multiple stacks. Owners and operators of facilities with more 
than one on-site stack from a boiler, industrial furnace, incinerator, 
or other thermal treatment unit subject to controls of metals emissions 
under a RCRA operating permit or interim status controls must comply 
with the screening limits for all such units assuming all hazardous 
waste is fed into the device with the worst-case stack based on 
dispersion characteristics. The worst-case stack is determined from the 
following equation as applied to each stack:

    K=HVT
Where:
    K=a parameter accounting for relative influence of stack height and 
plume rise;
    H=physical stack height (meters);
    V=stack gas flow rate (m\3\/second); and
    T=exhaust temperature ([deg]K).

The stack with the lowest value of K is the worst-case stack.

    (7) Criteria for facilities not eligible for screening limits. If 
any criteria below are met, the Tier I and Tier II screening limits do 
not apply. Owners and operators of such facilities must comply with 
either the Tier III standards provided by paragraph (d) of this section 
or with the adjusted Tier I feed rate screening limits provided by 
paragraph (e) of this section.
    (i) The device is located in a narrow valley less than one kilometer 
wide;
    (ii) The device has a stack taller than 20 meters and is located 
such that the terrain rises to the physical height within one kilometer 
of the facility;
    (iii) The device has a stack taller than 20 meters and is located 
within five kilometers of a shoreline of a large body of water such as 
an ocean or large lake;
    (iv) The physical stack height of any stack is less than 2.5 times 
the height of any building within five building heights or five 
projected building widths of the stack and the distance from the stack 
to the closest boundary is within five building heights or five 
projected building widths of the associated building; or
    (v) The Director determines that standards based on site-specific 
dispersion modeling are required.
    (8) Implementation. The feed rate of metals in each feedstream must 
be monitored to ensure that the feed rate screening limits are not 
exceeded.
    (c) Tier II emission rate screening limits. Emission rate screening 
limits are specified in appendix I as a function of terrain-adjusted 
effective stack height and terrain and land use in the vicinity of the 
facility. Criteria for facilities that are not eligible to comply with 
the screening limits are provided in paragraph (b)(7) of this section.
    (1) Noncarcinogenic metals. The emission rates of antimony, barium, 
lead, mercury, thallium, and silver shall not exceed the screening 
limits specified in appendix I of this part.
    (2) Carcinogenic metals. The emission rates of arsenic, cadmium, 
beryllium, and chromium shall not exceed values derived from the 
screening limits specified in appendix I of this part. The emission rate 
of each of these metals is limited to a level such that the sum of the 
ratios of the actual emission rate to the emission rate screening limit 
specified in appendix I shall not exceed 1.0, as provided by the 
following equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.002


where:
    n=number of carcinogenic metals
    AER=actual emission rate for metal ``i''
    ERSL=emission rate screening limit provided by appendix I of this 
part for metal ``i''.

    (3) Implementation. The emission rate limits must be implemented by 
limiting feed rates of the individual metals to levels during the trial 
burn (for new facilities or an interim status facility applying for a 
permit) or the compliance test (for interim status facilities). The feed 
rate averaging periods are the same as provided by paragraphs (b)(1)(i) 
and (ii) and (b)(2)(ii) of

[[Page 40]]

this section. The feed rate of metals in each feedstream must be 
monitored to ensure that the feed rate limits for the feedstreams 
specified under Secs. 266.102 or 266.103 are not exceeded.
    (4) Definitions and limitations. The definitions and limitations 
provided by paragraph (b) of this section for the following terms also 
apply to the Tier II emission rate screening limits provided by 
paragraph (c) of this section: terrain-adjusted effective stack height, 
good engineering practice stack height, terrain type, land use, and 
criteria for facilities not eligible to use the screening limits.
    (5) Multiple stacks. (i) Owners and operators of facilities with 
more than one onsite stack from a boiler, industrial furnace, 
incinerator, or other thermal treatment unit subject to controls on 
metals emissions under a RCRA operating permit or interim status 
controls must comply with the emissions screening limits for any such 
stacks assuming all hazardous waste is fed into the device with the 
worst-case stack based on dispersion characteristics.
    (ii) The worst-case stack is determined by procedures provided in 
paragraph (b)(6) of this section.
    (iii) For each metal, the total emissions of the metal from those 
stacks shall not exceed the screening limit for the worst-case stack.
    (d) Tier III and Adjusted Tier I site-specific risk assessment. The 
requirements of this paragraph apply to facilities complying with either 
the Tier III or Adjusted Tier I controls, except where specified 
otherwise.
    (1) General. Conformance with the Tier III metals controls must be 
demonstrated by emissions testing to determine the emission rate for 
each metal. In addition, conformance with either the Tier III or 
Adjusted Tier I metals controls must be demonstrated by air dispersion 
modeling to predict the maximum annual average off-site ground level 
concentration for each dispersion modeling to predict the maximum annual 
average off-site ground level concentration for each metal, and a 
demonstration that acceptable ambient levels are not exceeded.
    (2) Acceptable ambient levels. Appendices IV and V of this part list 
the acceptable ambient levels for purposes of this rule. Reference air 
concentrations (RACs) are listed for the noncarcinogenic metals and 
10[hyphen]5 risk-specific doses (RSDs) are listed for the 
carcinogenic metals. The RSD for a metal is the acceptable ambient level 
for that metal provided that only one of the four carcinogenic metals is 
emitted. If more than one carcinogenic metal is emitted, the acceptable 
ambient level for the carcinogenic metals is a fraction of the RSD as 
described in paragraph (d)(3) of this section.
    (3) Carcinogenic metals. For the carcinogenic metals, arsenic, 
cadmium, beryllium, and chromium, the sum of the ratios of the predicted 
maximum annual average off-site ground level concentrations (except that 
on-site concentrations must be considered if a person resides on site) 
to the risk-specific dose (RSD) for all carcinogenic metals emitted 
shall not exceed 1.0 as determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.003

where: n=number of carcinogenic metals

    (4) Noncarcinogenic metals. For the noncarcinogenic metals, the 
predicted maximum annual average off-site ground level concentration for 
each metal shall not exceed the reference air concentration (RAC).
    (5) Multiple stacks. Owners and operators of facilities with more 
than one on-site stack from a boiler, industrial furnace, incinerator, 
or other thermal treatment unit subject to controls on metals emissions 
under a RCRA operating permit or interim status controls must conduct 
emissions testing (except

[[Page 41]]

that facilities complying with Adjusted Tier I controls need not conduct 
emissions testing) and dispersion modeling to demonstrate that the 
aggregate emissions from all such on-site stacks do not result in an 
exceedance of the acceptable ambient levels.
    (6) Implementation. Under Tier III, the metals controls must be 
implemented by limiting feed rates of the individual metals to levels 
during the trial burn (for new facilities or an interim status facility 
applying for a permit) or the compliance test (for interim status 
facilities). The feed rate averaging periods are the same as provided by 
paragraphs (b)(1) (i) and (ii) and (b)(2)(ii) of this section. The feed 
rate of metals in each feedstream must be monitored to ensure that the 
feed rate limits for the feedstreams specified under Secs. 266.102 or 
266.103 are not exceeded.
    (e) Adjusted Tier I feed rate screening limits. The owner or 
operator may adjust the feed rate screening limits provided by appendix 
I of this part to account for site-specific dispersion modeling. Under 
this approach, the adjusted feed rate screening limit for a metal is 
determined by back-calculating from the acceptable ambient level 
provided by appendices IV and V of this part using dispersion modeling 
to determine the maximum allowable emission rate. This emission rate 
becomes the adjusted Tier I feed rate screening limit. The feed rate 
screening limits for carcinogenic metals are implemented as prescribed 
in paragraph (b)(2) of this section.
    (f) Alternative implementation approaches. (1) The Director may 
approve on a case-by-case basis approaches to implement the Tier II or 
Tier III metals emission limits provided by paragraphs (c) or (d) of 
this section alternative to monitoring the feed rate of metals in each 
feedstream.
    (2) The emission limits provided by paragraph (d) of this section 
must be determined as follows:
    (i) For each noncarcinogenic metal, by back-calculating from the RAC 
provided in appendix IV of this part to determine the allowable emission 
rate for each metal using the dilution factor for the maximum annual 
average ground level concentration predicted by dispersion modeling in 
conformance with paragraph (h) of this section; and
    (ii) For each carcinogenic metal by:
    (A) Back-calculating from the RSD provided in appendix V of this 
part to determine the allowable emission rate for each metal if that 
metal were the only carcinogenic metal emitted using the dilution factor 
for the maximum annual average ground level concentration predicted by 
dispersion modeling in conformance with paragraph (h) of this section; 
and
    (B) If more than one carcinogenic metal is emitted, selecting an 
emission limit for each carcinogenic metal not to exceed the emission 
rate determined by paragraph (f)(2)(ii)(A) of this section such that the 
sum for all carcinogenic metals of the ratios of the selected emission 
limit to the emission rate determined by that paragraph does not exceed 
1.0.
    (g) Emission testing--(1) General. Emission testing for metals shall 
be conducted using Method 0060, Determinations of Metals in Stack 
Emissions, EPA Publication SW-846, as incorporated by reference in 
Sec. 260.11 of this chapter.
    (2) Hexavalent chromium. Emissions of chromium are assumed to be 
hexavalent chromium unless the owner or operator conducts emissions 
testing to determine hexavalent chromium emissions using procedures 
prescribed in Method 0061, Determination of Hexavalent Chromium 
Emissions from Stationary Sources, EPA Publication SW-846, as 
incorporated by reference in Sec. 260.11 of this chapter.
    (h) Dispersion Modeling. Dispersion modeling required under this 
section shall be conducted according to methods recommended in appendix 
W of part 51 of this chapter (``Guideline on Air Quality Models 
(Revised)'' (1986) and its supplements), the ``Hazardous Waste 
Combustion Air Quality Screening Procedure'', provided in appendix IX of 
this part, or in Screening Procedures for Estimating the Air Quality 
Impact of Stationary Sources, Revised (incorporated by reference in 
Sec. 260.11) to predict the maximum annual average off-site ground level 
concentration. However, on-site concentrations must be considered when a 
person resides on-site.

    (i) Enforcement. For the purposes of permit enforcement, compliance 
with the operating requirements specified in the permit (under 
Sec. 266.102) will be regarded as compliance with this section. However, 
evidence that compliance with those permit conditions is insufficient to 
ensure compliance with the requirements of this section may be 
``information'' justifying modification or revocation and re-issuance of 
a permit under Sec. 270.41 of this chapter.

Sec. 266.107  Standards to control hydrogen chloride (HCl) and chlorine gas (Cl2) emissions.

    (a) General. The owner or operator must comply with the hydrogen 
chloride (HCl) and chlorine (Cl2) controls provided by 
paragraph (b), (c), or (e) of this section.
    (b) Screening limits--(1) Tier I feed rate screening limits. Feed 
rate screening limits are specified for total chlorine in appendix II of 
this part as a function of terrain-adjusted effective stack height and 
terrain and land use in the vicinity of the facility. The feed rate of 
total chlorine and chloride, both organic and inorganic, in all feed 
streams, including hazardous waste, fuels, and industrial furnace feed 
stocks shall not exceed the levels specified.
    (2) Tier II emission rate screening limits. Emission rate screening 
limits for HCl and Cl2 are specified in appendix III of this 
part as a function of terrain-adjusted effective stack height and 
terrain and land use in the vicinity of the facility. The stack emission 
rates of HCl and Cl2 shall not exceed the levels specified.
    (3) Definitions and limitations. The definitions and limitations 
provided by Sec. 266.106(b) for the following terms also apply to the 
screening limits provided by this paragraph: terrain-adjusted effective 
stack height, good engineering practice stack height, terrain type, land 
use, and criteria for facilities not eligible to use the screening 
limits.
    (4) Multiple stacks. Owners and operators of facilities with more 
than one on-site stack from a boiler, industrial furnace, incinerator, 
or other thermal treatment unit subject to controls on HCl or 
Cl2 emissions under a RCRA operating permit or interim status 
controls must comply with the Tier I and Tier II screening limits for 
those stacks assuming all hazardous waste is fed into the device with 
the worst-case stack based on dispersion characteristics.
    (i) The worst-case stack is determined by procedures provided in 
Sec. 266.106(b)(6).
    (ii) Under Tier I, the total feed rate of chlorine and chloride to 
all subject devices shall not exceed the screening limit for the worst-
case stack.
    (iii) Under Tier II, the total emissions of HCl and Cl2 
from all subject stacks shall not exceed the screening limit for the 
worst-case stack.
    (c) Tier III site-specific risk assessments--(1) General. 
Conformance with the Tier III controls must be demonstrated by emissions 
testing to determine the emission rate for HCl and Cl2, air 
dispersion modeling to predict the maximum annual average off-site 
ground level concentration for each compound, and a demonstration that 
acceptable ambient levels are not exceeded.
    (2) Acceptable ambient levels. Appendix IV of this part lists the 
reference air concentrations (RACs) for HCl (7 micrograms per cubic 
meter) and Cl2 (0.4 micrograms per cubic meter).
    (3) Multiple stacks. Owners and operators of facilities with more 
than one on-site stack from a boiler, industrial furnace, incinerator, 
or other thermal treatment unit subject to controls on HCl or 
Cl2 emissions under a RCRA operating permit or interim status 
controls must conduct emissions testing and dispersion modeling to 
demonstrate that the aggregate emissions from all such on-site stacks do 
not result in an exceedance of the acceptable ambient levels for HCl and 
Cl2.
    (d) Averaging periods. The HCl and Cl2 controls are 
implemented by limiting the feed rate of total chlorine and chloride in 
all feedstreams, including hazardous waste, fuels, and industrial 
furnace feed stocks. Under Tier I, the feed rate of total chloride and 
chlorine is limited to the Tier I Screening Limits. Under Tier II and 
Tier III, the feed rate of total chloride and chlorine is limited

[[Page 43]]

to the feed rates during the trial burn (for new facilities or an 
interim status facility applying for a permit) or the compliance test 
(for interim status facilities). The feed rate limits are based on 
either:
    (1) An hourly rolling average as defined in Sec. 266.102(e)(6); or
    (2) An instantaneous basis not to be exceeded at any time.
    (e) Adjusted Tier I feed rate screening limits. The owner or 
operator may adjust the feed rate screening limit provided by appendix 
II of this part to account for site-specific dispersion modeling. Under 
this approach, the adjusted feed rate screening limit is determined by 
back-calculating from the acceptable ambient level for Cl2 
provided by appendix IV of this part using dispersion modeling to 
determine the maximum allowable emission rate. This emission rate 
becomes the adjusted Tier I feed rate screening limit.
    (f) Emissions testing. Emissions testing for HCl and Cl2 
shall be conducted using the procedures described in Methods 0050 or 
0051, EPA Publication SW-846, as incorporated by reference in 
Sec. 260.11 of this chapter.
    (g) Dispersion modeling. Dispersion modeling shall be conducted 
according to the provisions of Sec. 266.106(h).
    (h) Enforcement. For the purposes of permit enforcement, compliance 
with the operating requirements specified in the permit (under 
Sec. 266.102) will be regarded as compliance with this section. However, 
evidence that compliance with those permit conditions is insufficient to 
ensure compliance with the requirements of this section may be 
``information'' justifying modification or revocation and re-issuance of 
a permit under Sec. 270.41 of this chapter.

    (2) The maximum hazardous waste firing rate does not exceed at any 
time 1 percent of the total fuel requirements for the device (hazardous 
waste plus other fuel) on a total heat input or mass input basis, 
whichever results in the lower mass feed rate of hazardous waste.
    (3) The hazardous waste has a minimum heating value of 5,000 Btu/lb, 
as generated; and
    (4) The hazardous waste fuel does not contain (and is not derived 
from) EPA Hazardous Waste Nos. F020, F021, F022, F023, F026, or F027.
    (b) Mixing with nonhazardous fuels. If hazardous waste fuel is mixed 
with a nonhazardous fuel, the quantity of hazardous waste before such 
mixing is used to comply with paragraph (a).
    (c) Multiple stacks. If an owner or operator burns hazardous waste 
in more than one on-site boiler or industrial furnace exempt under this 
section, the quantity limits provided by paragraph (a)(1) of this 
section are implemented according to the following equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.004


[[Page 44]]


where:
    n means the number of stacks;
    Actual Quantity Burned means the waste quantity burned per month in 
device ``i'';
    Allowable Quantity Burned means the maximum allowable exempt 
quantity for stack ``i'' from the table in (a)(1) above.
    Note: Hazardous wastes that are subject to the special requirements 
for small quantity generators under Sec. 261.5 of this chapter may be 
burned in an off-site device under the exemption provided by 
Sec. 266.108, but must be included in the quantity determination for the 
exemption.
    (d) Notification requirements. The owner or operator of facilities 
qualifying for the small quantity burner exemption under this section 
must provide a one-time signed, written notice to EPA indicating the 
following:
    (1) The combustion unit is operating as a small quantity burner of 
hazardous waste;
    (2) The owner and operator are in compliance with the requirements 
of this section; and
    (3) The maximum quantity of hazardous waste that the facility may 
burn per month as provided by Sec. 266.108(a)(1).
    (e) Recordkeeping requirements. The owner or operator must maintain 
at the facility for at least three years sufficient records documenting 
compliance with the hazardous waste quantity, firing rate, and heating 
value limits of this section. At a minimum, these records must indicate 
the quantity of hazardous waste and other fuel burned in each unit per 
calendar month, and the heating value of the hazardous waste.

Sec. 266.109  Low risk waste exemption.

    (a) Waiver of DRE standard. The DRE standard of Sec. 266.104(a) does 
not apply if the boiler or industrial furnace is operated in conformance 
with (a)(1) of this section and the owner or operator demonstrates by 
procedures prescribed in (a)(2) of this section that the burning will 
not result in unacceptable adverse health effects.
    (1) The device shall be operated as follows:
    (i) A minimum of 50 percent of fuel fired to the device shall be 
fossil fuel, fuels derived from fossil fuel, tall oil, or, if approved 
by the Director on a case-by-case basis, other nonhazardous fuel with 
combustion characteristics comparable to fossil fuel. Such fuels are 
termed ``primary fuel'' for purposes of this section. (Tall oil is a 
fuel derived from vegetable and rosin fatty acids.) The 50 percent 
primary fuel firing rate shall be determined on a total heat or mass 
input basis, whichever results in the greater mass feed rate of primary 
fuel fired;
    (ii) Primary fuels and hazardous waste fuels shall have a minimum 
as-fired heating value of 8,000 Btu/lb;
    (iii) The hazardous waste is fired directly into the primary fuel 
flame zone of the combustion chamber; and
    (iv) The device operates in conformance with the carbon monoxide 
controls provided by Sec. 266.104(b)(1). Devices subject to the 
exemption provided by this section are not eligible for the alternative 
carbon monoxide controls provided by Sec. 266.104(c).
    (2) Procedures to demonstrate that the hazardous waste burning will 
not pose unacceptable adverse public health effects are as follows:
    (i) Identify and quantify those nonmetal compounds listed in 
appendix VIII, part 261 of this chapter that could reasonably be 
expected to be present in the hazardous waste. The constituents excluded 
from analysis must be identified and the basis for their exclusion 
explained;
    (ii) Calculate reasonable, worst case emission rates for each 
constitutent identified in paragraph (a)(2)(i) of this section by 
assuming the device achieves 99.9 percent destruction and removal 
efficiency. That is, assume that 0.1 percent of the mass weight of each 
constitutent fed to the device is emitted.
    (iii) For each constituent identified in paragraph (a)(2)(i) of this 
section, use emissions dispersion modeling to predict the maximum annual 
average ground level concentration of the constituent.
    (A) Dispersion modeling shall be conducted using methods specified 
in Sec. 266.106(h).
    (B) Owners and operators of facilities with more than one on-site 
stack from a boiler or industrial furnace that is

[[Page 45]]

exempt under this section must conduct dispersion modeling of emissions 
from all stacks exempt under this section to predict ambient levels 
prescribed by this paragraph.
    (iv) Ground level concentrations of constituents predicted under 
paragraph (a)(2)(iii) of this section must not exceed the following 
levels:
    (A) For the noncarcinogenic compounds listed in appendix IV of this 
part, the levels established in appendix IV;
    (B) For the carcinogenic compounds listed in appendix V of this 
part, the sum for all constituents of the ratios of the actual ground 
level concentration to the level established in appendix V cannot exceed 
1.0; and
    (C) For constituents not listed in appendix IV or V, 0.1 micrograms 
per cubic meter.
    (b) Waiver of particular matter standard. The particulate matter 
standard of Sec. 266.105 does not apply if:
    (1) The DRE standard is waived under paragraph (a) of this section; 
and
    (2) The owner or operator complies with the Tier I or adjusted Tier 
I metals feed rate screening limits provided by Sec. 266.106 (b) or (e).

FR 42515, Aug. 27, 1991]



Sec. 266.110  Waiver of DRE trial burn for boilers.

    Boilers that operate under the special requirements of this section, 
and that do not burn hazardous waste containing (or derived from) EPA 
Hazardous Waste Nos. F020, F021, F022, F023, F026, or F027, are 
considered to be in conformance with the DRE standard of 
Sec. 266.104(a), and a trial burn to demonstrate DRE is waived. When 
burning hazardous waste:
    (a) A minimum of 50 percent of fuel fired to the device shall be 
fossil fuel, fuels derived from fossil fuel, tall oil, or, if approved 
by the Director on a case-by-case basis, other nonhazardous fuel with 
combustion characteristics comparable to fossil fuel. Such fuels are 
termed ``primary fuel'' for purposes of this section. (Tall oil is a 
fuel derived from vegetable and rosin fatty acids.) The 50 percent 
primary fuel firing rate shall be determined on a total heat or mass 
input basis, whichever results in the greater mass feed rate of primary 
fuel fired;
    (b) Boiler load shall not be less than 40 percent. Boiler load is 
the ratio at any time of the total heat input to the maximum design heat 
input;
    (c) Primary fuels and hazardous waste fuels shall have a minimum as-
fired heating value of 8,000 Btu/lb, and each material fired in a burner 
where hazardous waste is fired must have a heating value of at least 
8,000 Btu/lb, as-fired;
    (d) The device shall operate in conformance with the carbon monoxide 
standard provided by Sec. 266.104(b)(1). Boilers subject to the waiver 
of the DRE trial burn provided by this section are not eligible for the 
alternative carbon monoxide standard provided by Sec. 266.104(c);
    (e) The boiler must be a watertube type boiler that does not feed 
fuel using a stoker or stoker type mechanism; and
    (f) The hazardous waste shall be fired directly into the primary 
fuel flame zone of the combustion chamber with an air or steam 
atomization firing system, mechanical atomization system, or a rotary 
cup atomization system under the following conditions:
    (1) Viscosity. The viscosity of the hazardous waste fuel as-fired 
shall not exceed 300 SSU;
    (2) Particle size. When a high pressure air or steam atomizer, low 
pressure atomizer, or mechanical atomizer is used, 70% of the hazardous 
waste fuel must pass through a 200 mesh (74 micron) screen, and when a 
rotary cup atomizer is used, 70% of the hazardous waste must pass 
through a 100 mesh (150 micron) screen;
    (3) Mechanical atomization systems. Fuel pressure within a 
mechanical atomization system and fuel flow rate shall be maintained 
within the design range taking into account the viscosity and volatility 
of the fuel;
    (4) Rotary cup atomization systems. Fuel flow rate through a rotary 
cup atomization system must be maintained within the design range taking 
into account the viscosity and volatility of the fuel.

Sec. 266.111  Standards for direct transfer.

    (a) Applicability. The regulations in this section apply to owners 
and operators of boilers and industrial furnaces subject to 
Secs. 266.102 or 266.103 if hazardous waste is directly transferred from 
a transport vehicle to a boiler or industrial furnace without the use of 
a storage unit.
    (b) Definitions. (1) When used in this section, the following terms 
have the meanings given below:
    Direct transfer equipment means any device (including but not 
limited to, such devices as piping, fittings, flanges, valves, and 
pumps) that is used to distribute, meter, or control the flow of 
hazardous waste between a container (i.e., transport vehicle) and a 
boiler or industrial furnace.
    Container means any portable device in which hazardous waste is 
transported, stored, treated, or otherwise handled, and includes 
transport vehicles that are containers themselves (e.g., tank trucks, 
tanker-trailers, and rail tank cars), and containers placed on or in a 
transport vehicle.
    (2) This section references several requirements provided in 
subparts I and J of parts 264 and 265. For purposes of this section, the 
term ``tank systems'' in those referenced requirements means direct 
transfer equipment as defined in paragraph (b)(1) of this section.
    (c) General operating requirements. (1) No direct transfer of a 
pumpable hazardous waste shall be conducted from an open-top container 
to a boiler or industrial furnace.
    (2) Direct transfer equipment used for pumpable hazardous waste 
shall always be closed, except when necessary to add or remove the 
waste, and shall not be opened, handled, or stored in a manner that may 
cause any rupture or leak.
    (3) The direct transfer of hazardous waste to a boiler or industrial 
furnace shall be conducted so that it does not:
    (i) Generate extreme heat or pressure, fire, explosion, or violent 
reaction;
    (ii) Produce uncontrolled toxic mists, fumes, dusts, or gases in 
sufficient quantities to threaten human health;
    (iii) Produce uncontrolled flammable fumes or gases in sufficient 
quantities to pose a risk of fire or explosions;
    (iv) Damage the structural integrity of the container or direct 
transfer equipment containing the waste;
    (v) Adversely affect the capability of the boiler or industrial 
furnace to meet the standards provided by Secs. 266.104 through 266.107; 
or
    (vi) Threaten human health or the environment.
    (4) Hazardous waste shall not be placed in direct transfer 
equipment, if it could cause the equipment or its secondary containment 
system to rupture, leak, corrode, or otherwise fail.
    (5) The owner or operator of the facility shall use appropriate 
controls and practices to prevent spills and overflows from the direct 
transfer equipment or its secondary containment systems. These include 
at a minimum:
    (i) Spill prevention controls (e.g., check valves, dry discount 
couplings); and
    (ii) Automatic waste feed cutoff to use if a leak or spill occurs 
from the direct transfer equipment.
    (d) Areas where direct transfer vehicles (containers) are located. 
Applying the definition of container under this section, owners and 
operators must comply with the following requirements:
    (1) The containment requirements of Sec. 264.175 of this chapter;
    (2) The use and management requirements of subpart I, part 265 of 
this chapter, except for Secs. 265.170 and 265.174, and except that in 
lieu of the special requirements of Sec. 265.176 for ignitable or 
reactive waste, the owner or operator may comply with the requirements 
for the maintenance of protective distances between the waste management 
area and any public ways, streets, alleys, or an adjacent property line 
that can be built upon as required in Tables 2-1 through 2-6 of the 
National Fire Protection Association's (NFPA) ``Flammable and 
Combustible Liquids Code,'' (1977 or 1981), (incorporated by reference, 
see Sec. 260.11). The owner or operator must obtain and keep on file at 
the facility a written certification by the local Fire Marshall that the 
installation meets the subject NFPA codes; and
    (3) The closure requirements of Sec. 264.178 of this chapter.

[[Page 47]]

    (e) Direct transfer equipment. Direct transfer equipment must meet 
the following requirements:
    (1) Secondary containment. Owners and operators shall comply with 
the secondary containment requirements of Sec. 265.193 of this chapter, 
except for paragraphs 265.193 (a), (d), (e), and (i) as follows:
    (i) For all new direct transfer equipment, prior to their being put 
into service; and
    (ii) For existing direct transfer equipment within 2 years after 
August 21, 1991.
    (2) Requirements prior to meeting secondary containment 
requirements. (i) For existing direct transfer equipment that does not 
have secondary containment, the owner or operator shall determine 
whether the equipment is leaking or is unfit for use. The owner or 
operator shall obtain and keep on file at the facility a written 
assessment reviewed and certified by a qualified, registered 
professional engineer in accordance with Sec. 270.11(d) of this chapter 
that attests to the equipment's integrity by August 21, 1992.
    (ii) This assessment shall determine whether the direct transfer 
equipment is adequately designed and has sufficient structural strength 
and compatibility with the waste(s) to be transferred to ensure that it 
will not collapse, rupture, or fail. At a minimum, this assessment shall 
consider the following:

Sec. 266.112  Regulation of residues.

    A residue derived from the burning or processing of hazardous waste 
in a boiler or industrial furnace is not excluded from the definition of 
a hazardous waste under Sec. 261.4(b) (4), (7), or (8) unless the device 
and the owner or operator meet the following requirements:
    (a) The device meets the following criteria:

[[Page 48]]

    (1) Boilers. Boilers must burn at least 50% coal on a total heat 
input or mass input basis, whichever results in the greater mass feed 
rate of coal;
    (2) Ore or mineral furnaces. Industrial furnaces subject to 
Sec. 261.4(b)(7) must process at least 50% by weight normal, 
nonhazardous raw materials;
    (3) Cement kilns. Cement kilns must process at least 50% by weight 
normal cement-production raw materials;
    (b) The owner or operator demonstrates that the hazardous waste does 
not significantly affect the residue by demonstrating conformance with 
either of the following criteria:
    (1) Comparison of waste-derived residue with normal residue. The 
waste-derived residue must not contain appendix VIII, part 261 
constituents (toxic constituents) that could reasonably be attributable 
to the hazardous waste at concentrations significantly higher than in 
residue generated without burning or processing of hazardous waste, 
using the following procedure. Toxic compounds that could reasonably be 
attributable to burning or processing the hazardous waste (constituents 
of concern) include toxic constituents in the hazardous waste, and the 
organic compounds listed in appendix VIII of this part that may be 
generated as products of incomplete combustion. Sampling and analyses 
shall be in conformance with procedures prescribed in Test Methods for 
Evaluating Solid Waste, Physical/Chemical Methods, incorporated by 
reference in Sec. 260.11(a) of this chapter. For polychlorinated 
dibenzo-p-dioxins and polychlorinated dibenzo-furans, analyses must be 
performed to determine specific congeners and homologues, and the 
results converted to 2,3,7,8-TCDD equivalent values using the procedure 
specified in section 4.0 of appendix IX of this part.
    (i) Normal residue. Concentrations of toxic constituents of concern 
in normal residue shall be determined based on analyses of a minimum of 
10 samples representing a minimum of 10 days of operation. Composite 
samples may be used to develop a sample for analysis provided that the 
compositing period does not exceed 24 hours. The upper tolerance limit 
(at 95% confidence with a 95% proportion of the sample distribution) of 
the concentration in the normal residue shall be considered the 
statistically-derived concentration in the normal residue. If changes in 
raw materials or fuels reduce the statistically-derived concentrations 
of the toxic constituents of concern in the normal residue, the 
statistically-derived concentrations must be revised or statistically-
derived concentrations of toxic constituents in normal residue must be 
established for a new mode of operation with the new raw material or 
fuel. To determine the upper tolerance limit in the normal residue, the 
owner or operator shall use statistical procedures prescribed in 
``Statistical Methodology for Bevill Residue Determinations'' in 
appendix IX of this part.
    (ii) Waste-derived residue. Waste-derived residue shall be sampled 
and analyzed as often as necessary to determine whether the residue 
generated during each 24-hour period has concentrations of toxic 
constituents that are higher than the concentrations established for the 
normal residue under paragraph (b)(1)(i) of this section. If so, 
hazardous waste burning has significantly affected the residue and the 
residue shall not be excluded from the definition of a hazardous waste. 
Concentrations of toxic constituents of concern in the waste-derived 
residue shall be determined based on analysis of one or more samples 
obtained over a 24-hour period. Multiple samples may be analyzed, and 
multiple samples may be taken to form a composite sample for analysis 
provided that the sampling period does not exceed 24 hours. If more than 
one sample is analyzed to characterize waste-derived residues generated 
over a 24-hour period, the concentration of each toxic constituent shall 
be the arithmetic mean of the concentrations in the samples. No results 
may be disregarded; or
    (2) Comparison of waste-derived residue concentrations with health-
based limits-- (i) Nonmetal constituents. The concentration of each 
nonmetal toxic constituent of concern (specified in paragraph (b)(1) of 
this section) in the waste-derived residue must not exceed the health-
based level specified in appendix VII of this part, or the level of 
detection (using analytical procedures prescribed in SW-846), whichever 
is higher. If a health-based limit for a

[[Page 49]]

constituent of concern is not listed in appendix VII of this part, then 
a limit of 0.002 micrograms per kilogram or the level of detection 
(using analytical procedures contained in SW-846, or other appropriate 
methods), whichever is higher, must be used. The levels specified in 
appendix VII of this part (and the default level of 0.002 micrograms per 
kilogram or the level of detection for constituents as identified in 
Note 1 of appendix VII of this paragraph) are administratively stayed 
under the condition, for those constituents specified in paragraph 
(b)(1) of this section, that the owner or operator complies with 
alternative levels defined as the land disposal restriction limits 
specified in Sec. 268.43 of this chapter for F039 nonwastewaters. In 
complying with those alternative levels, if an owner or operator is 
unable to detect a constituent despite documenting use of best good-
faith efforts as defined by applicable Agency guidance or standards, the 
owner or operator is deemed to be in compliance for that constituent. 
Until new guidance or standards are developed, the owner or operator may 
demonstrate such good faith efforts by achieving a detection limit for 
the constituent that does not exceed an order of magnitude above the 
level provided by Sec. 268.43 of this chapter for F039 nonwastewaters. 
In complying with the Sec. 268.43 of this chapter F039 nonwastewater 
levels for polychlorinated dibenzo-p-dioxins and polychlorinated 
dibenzo-furans, analyses must be performed for total hexachlorodibenzo-
p-dioxins, total hexachlorodibenzofurans, total pentachlorodibenzo-p-
dioxins, total pentachlorodibenzofurans, total tetrachlorodibenzo-p-
dioxins, and total tetrachlorodibenzofurans.

    Note to this paragraph: The administrative stay, under the condition 
that the owner or operator complies with alternative levels defined as 
the land disposal restriction limits specified in Sec. 268.43 of this 
chapter for F039 nonwastewaters, remains in effect until further 
administrative action is taken and notice is published in the Federal 
Register and the Code of Federal Regulations.
    (ii) Metal constituents. The concentration of metals in an extract 
obtained using the Toxicity Characteristic Leaching Procedure of 
Sec. 261.24 of this chapter must not exceed the levels specified in 
appendix VII of this part; and
    (iii) Sampling and analysis. Waste-derived residue shall be sampled 
and analyzed as often as necessary to determine whether the residue 
generated during each 24-hour period has concentrations of toxic 
constituents that are higher than the health-based levels. 
Concentrations of toxic constituents of concern in the waste-derived 
residue shall be determined based on analysis of one or more samples 
obtained over a 24-hour period. Multiple samples may be analyzed, and 
multiple samples may be taken to form a composite sample for analysis 
provided that the sampling period does not exceed 24 hours. If more than 
one sample is analyzed to characterize waste-derived residues generated 
over a 24-hour period, the concentration of each toxic constituent shall 
be the arithmetic mean of the concentrations in the samples. No results 
may be disregarded; and
    (c) Records sufficient to document compliance with the provisions of 
this section shall be retained until closure of the boiler or industrial 
furnace unit. At a minimum, the following shall be recorded.
    (1) Levels of constituents in appendix VIII, part 261, that are 
present in waste-derived residues;
    (2) If the waste-derived residue is compared with normal residue 
under paragraph (b)(1) of this section:
    (i) The levels of constituents in appendix VIII, part 261, that are 
present in normal residues; and
    (ii) Data and information, including analyses of samples as 
necessary, obtained to determine if changes in raw materials or fuels 
would reduce the concentration of toxic constituents of concern in the 
normal residue.

[[Page 50]]



Sec. 266.200  Applicability.

    (a) The regulations in this subpart identify when military munitions 
become a solid waste, and, if these wastes are also hazardous under this 
subpart or 40 CFR part 261, the management standards that apply to these 
wastes.
    (b) Unless otherwise specified in this subpart, all applicable 
requirements in 40 CFR parts 260 through 270 apply to waste military 
munitions.



Sec. 266.201  Definitions.

    In addition to the definitions in 40 CFR 260.10, the following 
definitions apply to this subpart:
    Active range means a military range that is currently in service and 
is being regularly used for range activities.
    Chemical agents and munitions are defined as in 50 U.S.C. section 
1521(j)(1).
    Director is as defined in 40 CFR 270.2.
    Explosives or munitions emergency response specialist is as defined 
in 40 CFR 260.10.
    Explosives or munitions emergency is as defined in 40 CFR 260.10.
    Explosives or munitions emergency response is as defined in 40 CFR 
260.10.
    Inactive range means a military range that is not currently being 
used, but that is still under military control and considered by the 
military to be a potential range area, and that has not been put to a 
new use that is incompatible with range activities.
    Military means the Department of Defense (DOD), the Armed Services, 
Coast Guard, National Guard, Department of Energy (DOE), or other 
parties under contract or acting as an agent for the foregoing, who 
handle military munitions.
    Military munitions is as defined in 40 CFR 260.10.
    Military range means designated land and water areas set aside, 
managed, and used to conduct research on, develop, test, and evaluate 
military munitions and explosives, other ordnance, or weapon systems, or 
to train military personnel in their use and handling. Ranges include 
firing lines and positions, maneuver areas, firing lanes, test pads, 
detonation pads, impact areas, and buffer zones with restricted access 
and exclusionary areas.
    Unexploded ordnance (UXO) means military munitions that have been 
primed, fused, armed, or otherwise prepared for action, and have been 
fired, dropped, launched, projected, or placed in such a manner as to 
constitute a hazard to operations, installation, personnel, or material 
and remain unexploded either by malfunction, design, or any other cause.



Sec. 266.202  Definition of solid waste.

    (a) A military munition is not a solid waste when:
    (1) Used for its intended purpose, including:
    (i) Use in training military personnel or explosives and munitions 
emergency response specialists (including training in proper destruction 
of unused propellant or other munitions); or
    (ii) Use in research, development, testing, and evaluation of 
military munitions, weapons, or weapon systems; or
    (iii) Recovery, collection, and on-range destruction of unexploded 
ordnance and munitions fragments during range clearance activities at 
active or inactive ranges. However, ``use for intended purpose'' does 
not include the on-range disposal or burial of unexploded ordnance and 
contaminants when the burial is not a result of product use.
    (2) An unused munition, or component thereof, is being repaired, 
reused, recycled, reclaimed, disassembled, reconfigured, or otherwise 
subjected to materials recovery activities, unless such activities 
involve use constituting disposal as defined in 40 CFR 261.2(c)(1), or 
burning for energy recovery as defined in 40 CFR 261.2(c)(2).
    (b) An unused military munition is a solid waste when any of the 
following occurs:
    (1) The munition is abandoned by being disposed of, burned, 
detonated (except during intended use as specified in paragraph (a) of 
this section), incinerated, or treated prior to disposal; or
    (2) The munition is removed from storage in a military magazine or 
other storage area for the purpose of being disposed of, burned, or 
incinerated, or treated prior to disposal, or
    (3) The munition is deteriorated or damaged (e.g., the integrity of 
the munition is compromised by cracks, leaks, or other damage) to the 
point

[[Page 51]]

that it cannot be put into serviceable condition, and cannot reasonably 
be recycled or used for other purposes; or
    (4) The munition has been declared a solid waste by an authorized 
military official.
    (c) A used or fired military munition is a solid waste:
    (1) When transported off range or from the site of use, where the 
site of use is not a range, for the purposes of storage, reclamation, 
treatment, disposal, or treatment prior to disposal; or
    (2) If recovered, collected, and then disposed of by burial, or 
landfilling either on or off a range.
    (d) For purposes of RCRA section 1004(27), a used or fired military 
munition is a solid waste, and, therefore, is potentially subject to 
RCRA corrective action authorities under sections 3004(u) and (v), and 
3008(h), or imminent and substantial endangerment authorities under 
section 7003, if the munition lands off-range and is not promptly 
rendered safe and/or retrieved. Any imminent and substantial threats 
associated with any remaining material must be addressed. If remedial 
action is infeasible, the operator of the range must maintain a record 
of the event for as long as any threat remains. The record must include 
the type of munition and its location (to the extent the location is 
known).



Sec. 266.203  Standards applicable to the transportation of solid waste military munitions.

    (a) Criteria for hazardous waste regulation of waste non-chemical 
military munitions in transportation. (1) Waste military munitions that 
are being transported and that exhibit a hazardous waste characteristic 
or are listed as hazardous waste under 40 CFR part 261, are listed or 
identified as a hazardous waste (and thus are subject to regulation 
under 40 CFR parts 260 through 270), unless all the following conditions 
are met:
    (i) The waste military munitions are not chemical agents or chemical 
munitions;
    (ii) The waste military munitions must be transported in accordance 
with the Department of Defense shipping controls applicable to the 
transport of military munitions;
    (iii) The waste military munitions must be transported from a 
military owned or operated installation to a military owned or operated 
treatment, storage, or disposal facility; and
    (iv) The transporter of the waste must provide oral notice to the 
Director within 24 hours from the time the transporter becomes aware of 
any loss or theft of the waste military munitions, or any failure to 
meet a condition of paragraph (a)(1) of this section that may endanger 
health or the environment. In addition, a written submission describing 
the circumstances shall be provided within 5 days from the time the 
transporter becomes aware of any loss or theft of the waste military 
munitions or any failure to meet a condition of paragraph (a)(1) of this 
section.
    (2) If any waste military munitions shipped under paragraph (a)(1) 
of this section are not received by the receiving facility within 45 
days of the day the waste was shipped, the owner or operator of the 
receiving facility must report this non-receipt to the Director within 5 
days.
    (3) The exemption in paragraph (a)(1) of this section from 
regulation as hazardous waste shall apply only to the transportation of 
non-chemical waste military munitions. It does not affect the regulatory 
status of waste military munitions as hazardous wastes with regard to 
storage, treatment or disposal.
    (4) The conditional exemption in paragraph (a)(1) of this section 
applies only so long as all of the conditions in paragraph (a)(1) of 
this section are met.
    (b) Reinstatement of exemption. If any waste military munition loses 
its exemption under paragraph (a)(1) of this section, an application may 
be filed with the Director for reinstatement of the exemption from 
hazardous waste transportation regulation with respect to such munition 
as soon as the munition is returned to compliance with the conditions of 
paragraph (a)(1) of this section. If the Director finds that 
reinstatement of the exemption is appropriate based on factors such as 
the transporter's provision of a satisfactory explanation of the 
circumstances of the violation, or a demonstration

[[Page 52]]

that the violations are not likely to recur, the Director may reinstate 
the exemption under paragraph (a)(1) of this section. If the Director 
does not take action on the reinstatement application within 60 days 
after receipt of the application, then reinstatement shall be deemed 
granted, retroactive to the date of the application. However, the 
Director may terminate a conditional exemption reinstated by default in 
the preceding sentence if the Director finds that reinstatement is 
inappropriate based on factors such as the transporter's failure to 
provide a satisfactory explanation of the circumstances of the 
violation, or failure to demonstrate that the violations are not likely 
to recur. In reinstating the exemption under paragraph (a)(1) of this 
section, the Director may specify additional conditions as are necessary 
to ensure and document proper transportation to protect human health and 
the environment.
    (c) Amendments to DOD shipping controls. The Department of Defense 
shipping controls applicable to the transport of military munitions 
referenced in paragraph (a)(1)(ii) of this section are Government Bill 
of Lading (GBL) (GSA Standard Form 1109), requisition tracking form DD 
Form 1348, the Signature and Talley Record (DD Form 1907), Special 
Instructions for Motor Vehicle Drivers (DD Form 836), and the Motor 
Vehicle Inspection Report (DD Form 626) in effect on November 8, 1995, 
except as provided in the following sentence. Any amendments to the 
Department of Defense shipping controls shall become effective for 
purposes of paragraph (a)(1) of this section on the date the Department 
of Defense publishes notice in the Federal Register that the shipping 
controls referenced in paragraph (a)(1)(ii) of this section have been 
amended.



Sec. 266.204  Standards applicable to emergency responses.

    Explosives and munitions emergencies involving military munitions or 
explosives are subject to 40 CFR 262.10(i), 263.10(e), 264.1(g)(8), 
265.1(c)(11), and 270.1(c)(3), or alternatively to 40 CFR 270.61.



Sec. 266.205  Standards applicable to the storage of solid waste military munitions.

    (a) Criteria for hazardous waste regulation of waste non-chemical 
military munitions in storage. (1) Waste military munitions in storage 
that exhibit a hazardous waste characteristic or are listed as hazardous 
waste under 40 CFR Part 261, are listed or identified as a hazardous 
waste (and thus are subject to regulation under 40 CFR Parts 260 through 
279), unless all the following conditions are met:
    (i) The waste military munitions are not chemical agents or chemical 
munitions.
    (ii) The waste military munitions must be subject to the 
jurisdiction of the Department of Defense Explosives Safety Board 
(DDESB).
    (iii) The waste military munitions must be stored in accordance with 
the DDESB storage standards applicable to waste military munitions.
    (iv) Within 90 days of August 12, 1997 or within 90 days of when a 
storage unit is first used to store waste military munitions, whichever 
is later, the owner or operator must notify the Director of the location 
of any waste storage unit used to store waste military munitions for 
which the conditional exemption in paragraph (a)(1) is claimed.
    (v) The owner or operator must provide oral notice to the Director 
within 24 hours from the time the owner or operator becomes aware of any 
loss or theft of the waste military munitions, or any failure to meet a 
condition of paragraph (a)(1) that may endanger health or the 
environment. In addition, a written submission describing the 
circumstances shall be provided within 5 days from the time the owner or 
operator becomes aware of any loss or theft of the waste military 
munitions or any failure to meet a condition of paragraph (a)(1) of this 
section.
    (vi) The owner or operator must inventory the waste military 
munitions at least annually, must inspect the waste military munitions 
at least quarterly for compliance with the conditions of paragraph 
(a)(1) of this section, and must maintain records of the findings of 
these inventories and inspections for at least three years.

[[Page 53]]

    (vii) Access to the stored waste military munitions must be limited 
to appropriately trained and authorized personnel.
    (2) The conditional exemption in paragraph (a)(1) of this section 
from regulation as hazardous waste shall apply only to the storage of 
non-chemical waste military munitions. It does not affect the regulatory 
status of waste military munitions as hazardous wastes with regard to 
transportation, treatment or disposal.
    (3) The conditional exemption in paragraph (a)(1) of this section 
applies only so long as all of the conditions in paragraph (a)(1) of 
this section are met.
    (b) Notice of termination of waste storage. The owner or operator 
must notify the Director when a storage unit identified in paragraph 
(a)(1)(iv) of this section will no longer be used to store waste 
military munitions.
    (c) Reinstatement of conditional exemption. If any waste military 
munition loses its conditional exemption under paragraph (a)(1) of this 
section, an application may be filed with the Director for reinstatement 
of the conditional exemption from hazardous waste storage regulation 
with respect to such munition as soon as the munition is returned to 
compliance with the conditions of paragraph (a)(1) of this section. If 
the Director finds that reinstatement of the conditional exemption is 
appropriate based on factors such as the owner's or operator's provision 
of a satisfactory explanation of the circumstances of the violation, or 
a demonstration that the violations are not likely to recur, the 
Director may reinstate the conditional exemption under paragraph (a)(1) 
of this section. If the Director does not take action on the 
reinstatement application within 60 days after receipt of the 
application, then reinstatement shall be deemed granted, retroactive to 
the date of the application. However, the Director may terminate a 
conditional exemption reinstated by default in the preceding sentence if 
he/she finds that reinstatement is inappropriate based on factors such 
as the owner's or operator's failure to provide a satisfactory 
explanation of the circumstances of the violation, or failure to 
demonstrate that the violations are not likely to recur. In reinstating 
the conditional exemption under paragraph (a)(1) of this section, the 
Director may specify additional conditions as are necessary to ensure 
and document proper storage to protect human health and the environment.
    (d) Waste chemical munitions. (1) Waste military munitions that are 
chemical agents or chemical munitions and that exhibit a hazardous waste 
characteristic or are listed as hazardous waste under 40 CFR Part 261, 
are listed or identified as a hazardous waste and shall be subject to 
the applicable regulatory requirements of RCRA subtitle C.
    (2) Waste military munitions that are chemical agents or chemical 
munitions and that exhibit a hazardous waste characteristic or are 
listed as hazardous waste under 40 CFR Part 261, are not subject to the 
storage prohibition in RCRA section 3004(j), codified at 40 CFR 268.50.
    (e) Amendments to DDESB storage standards. The DDESB storage 
standards applicable to waste military munitions, referenced in 
paragraph (a)(1)(iii) of this section, are DOD 6055.9-STD (``DOD 
Ammunition and Explosive Safety Standards''), in effect on November 8, 
1995, except as provided in the following sentence. Any amendments to 
the DDESB storage standards shall become effective for purposes of 
paragraph (a)(1) of this section on the date the Department of Defense 
publishes notice in the Federal Register that the DDESB standards 
referenced in paragraph (a)(1) of this section have been amended.



Sec. 266.206  Standards applicable to the treatment and disposal of waste military munitions.

       Storage and Treatment Conditional Exemption and Eligibility



Sec. 266.220  What does a storage and treatment conditional exemption do?

    The storage and treatment conditional exemption exempts your low-
level mixed waste from the regulatory definition of hazardous waste in 
40 CFR 261.3 if your waste meets the eligibility criteria in 
Sec. 266.225 and you meet the conditions in Sec. 266.230.



Sec. 266.225  What wastes are eligible for the storage and treatment conditional exemption?

    Low-level mixed waste (LLMW), defined in Sec. 266.210, is eligible 
for this conditional exemption if it is generated

[[Page 55]]

and managed by you under a single NRC or NRC Agreement State license. 
(Mixed waste generated at a facility with a different license number and 
shipped to your facility for storage or treatment requires a permit and 
is ineligible for this exemption. In addition, NARM waste is ineligible 
this exemption.)



Sec. 266.230  What conditions must you meet for your LLMW to qualify for and maintain a storage and treatment exemption?

    (a) For your LLMW to qualify for the exemption you must notify us in 
writing by certified delivery that you are claiming a conditional 
exemption for the LLMW stored on your facility. The dated notification 
must include your name, address, RCRA identification number, NRC or NRC 
Agreement State license number, the waste code(s) and storage unit(s) 
for which you are seeking an exemption, and a statement that you meet 
the conditions of this subpart. Your notification must be signed by your 
authorized representative who certifies that the information in the 
notification is true, accurate, and complete. You must notify us of your 
claim either within 90 days of the effective date of this rule in your 
State, or within 90 days of when a storage unit is first used to store 
conditionally exempt LLMW.
    (b) To qualify for and maintain an exemption for your LLMW you must:
    (1) Store your LLMW waste in tanks or containers in compliance with 
the requirements of your license that apply to the proper storage of 
low-level radioactive waste (not including those license requirements 
that relate solely to recordkeeping);
    (2) Store your LLMW in tanks or containers in compliance with 
chemical compatibility requirements of a tank or container in 40 CFR 
264.177, or 264.199 or 40 CFR 265.177, or 265.199;
    (3) Certify that facility personnel who manage stored conditionally 
exempt LLMW are trained in a manner that ensures that the conditionally 
exempt waste is safely managed and includes training in chemical waste 
management and hazardous materials incidents response that meets the 
personnel training standards found in 40 CFR 265.16(a)(3);
    (4) Conduct an inventory of your stored conditionally exempt LLMW at 
least annually and inspect it at least quarterly for compliance with 
subpart N of this part; and
    (5) Maintain an accurate emergency plan and provide it to all local 
authorities who may have to respond to a fire, explosion, or release of 
hazardous waste or hazardous constituents. Your plan must describe 
emergency response arrangements with local authorities; describe 
evacuation plans; list the names, addresses, and telephone numbers of 
all facility personnel qualified to work with local authorities as 
emergency coordinators; and list emergency equipment.

                                Treatment



Sec. 266.235  What waste treatment does the storage and treatment conditional exemption allow?

    You may treat your low-level mixed waste at your facility within a 
tank or container in accordance with the terms of your NRC or NRC 
Agreement State license. Treatment that cannot be done in a tank or 
container without a RCRA permit (such as incineration) is not allowed 
under this exemption.

                      Loss of Conditional Exemption



Sec. 266.240  How could you lose the conditional exemption for your LLMW and what action must you take?

    (a) Your LLMW will automatically lose the storage and treatment 
conditional exemption if you fail to meet any of the conditions 
specified in Sec. 266.230. When your LLMW loses the exemption, you must 
immediately manage that waste which failed the condition as RCRA 
hazardous waste, and the storage unit storing the LLMW immediately 
becomes subject to RCRA hazardous waste container and/or tank storage 
requirements.
    (1) If you fail to meet any of the conditions specified in 
Sec. 266.230 you must report to us and the NRC, or the oversight agency 
in the NRC Agreement State, in writing by certified delivery within 30 
days of learning of the failure. Your report must be signed by

[[Page 56]]

your authorized representative certifying that the information provided 
is true, accurate, and complete. This report must include:
    (i) The specific condition(s) you failed to meet;
    (ii) A description of the LLMW (including the waste name, hazardous 
waste codes and quantity) and storage location at the facility; and
    (iii) The date(s) on which you failed to meet the condition(s).
    (2) If the failure to meet any of the conditions may endanger human 
health or the environment, you must also immediately notify us orally 
within 24 hours and follow up with a written notification within five 
days. Failures that may endanger human health or the environment 
include, but are not limited to, discharge of a CERCLA reportable 
quantity or other leaking or exploding tanks or containers, or detection 
of radionuclides above background or hazardous constituents in the 
leachate collection system of a storage area. If the failure may 
endanger human health or the environment, you must follow the provisions 
of your emergency plan.
    (b) We may terminate your conditional exemption for your LLMW, or 
require you to meet additional conditions to claim a conditional 
exemption, for serious or repeated noncompliance with any requirement(s) 
of subpart N of this part.



Sec. 266.245  If you lose the storage and treatment conditional exemption for your LLMW, can the exemption be reclaimed?

    (a) You may reclaim the storage and treatment exemption for your 
LLMW if:
    (1) You again meet the conditions specified in Sec. 266.230; and
    (2) You send us a notice by certified delivery that you are 
reclaiming the exemption for your LLMW. Your notice must be signed by 
your authorized representative certifying that the information contained 
in your notice is true, complete, and accurate. In your notice you must 
do the following:
    (i) Explain the circumstances of each failure.
    (ii) Certify that you have corrected each failure that caused you to 
lose the exemption for your LLMW and that you again meet all the 
conditions as of the date you specify.
    (iii) Describe plans that you have implemented, listing specific 
steps you have taken, to ensure the conditions will be met in the 
future.
    (iv) Include any other information you want us to consider when we 
review your notice reclaiming the exemption.
    (b) We may terminate a reclaimed conditional exemption if we find 
that your claim is inappropriate based on factors including, but not 
limited to, the following: you have failed to correct the problem; you 
explained the circumstances of the failure unsatisfactorily; or you 
failed to implement a plan with steps to prevent another failure to meet 
the conditions of Sec. 266.230. In reviewing a reclaimed conditional 
exemption under this section, we may add conditions to the exemption to 
ensure that waste management during storage and treatment of the LLMW 
will protect human health and the environment.

                              Recordkeeping



Sec. 266.250  What records must you keep at your facility and for how long?

Agreement State license, you must keep records as follows:
    (1) Your initial notification records, return receipts, reports to 
us of failure(s) to meet the exemption conditions, and all records 
supporting any reclaim of an exemption;
    (2) Records of your LLMW annual inventories, and quarterly 
inspections;
    (3) Your certification that facility personnel who manage stored 
mixed waste are trained in safe management of LLMW including training in 
chemical waste management and hazardous materials incidents response; 
and
    (4) Your emergency plan as specified in Sec. 266.230(b).
    (b) You must maintain records concerning notification, personnel 
trained, and your emergency plan for as long as you claim this exemption 
and for three years thereafter, or in accordance with NRC regulations 
under 10 CFR part 20 (or equivalent NRC Agreement State

[[Page 57]]

regulations), whichever is longer. You must maintain records concerning 
your annual inventory and quarterly inspections for three years after 
the waste is sent for disposal, or in accordance with NRC regulations 
under 10 CFR part 20 (or equivalent NRC Agreement State regulations), 
whichever is longer.

                            Reentry Into RCRA



Sec. 266.255  When is your LLMW no longer eligible for the storage and treatment conditional exemption?

    (a) When your LLMW has met the requirements of your NRC or NRC 
Agreement State license for decay-in-storage and can be disposed of as 
non-radioactive waste, then the conditional exemption for storage no 
longer applies. On that date your waste is subject to hazardous waste 
regulation under the relevant sections of 40 CFR parts 260 through 271, 
and the time period for accumulation of a hazardous waste as specified 
in 40 CFR 262.34 begins.
    (b) When your conditionally exempt LLMW, which has been generated 
and stored under a single NRC or NRC Agreement State license number, is 
removed from storage, it is no longer eligible for the storage and 
treatment exemption. However, your waste may be eligible for the 
transportation and disposal conditional exemption at Sec. 266.305.

                          Storage Unit Closure



Sec. 266.260  Do closure requirements apply to units that stored LLMW prior to the effective date of Subpart N?

    Interim status and permitted storage units that have been used to 
store only LLMW prior to the effective date of subpart N of this part 
and, after that date, store only LLMW which becomes exempt under this 
subpart N, are not subject to the closure requirements of 40 CFR parts 
264 and 265. Storage units (or portions of units) that have been used to 
store both LLMW and non-mixed hazardous waste prior to the effective 
date of subpart N or are used to store both after that date remain 
subject to closure requirements with respect to the non-mixed hazardous 
waste.

            Transportation and Disposal Conditional Exemption



Sec. 266.305  What does the transportation and disposal conditional exemption do?

after it first generates or causes USFRS XL waste to be regulated.
    (c) USFRS will conduct a preliminary evaluation of any person it 
wishes to propose to EPA to add to the USFRS XL Project as a generator. 
USFRS will complete this preliminary evaluation prior to proposing to 
EPA to add such a person to the USFRS XL Project. The preliminary 
evaluation will consist of the following activities: USFRS will require 
any person who wishes to become a USFRS XL waste generator to complete 
and sign the USFRS XL Waste Application Form; USFRS will complete the 
waste characterization required by 40 CFR 266.406(b); USFRS

[[Page 62]]

will evaluate the person's storage area for the USFRS XL waste to 
determine whether it meets the standards of this subpart O; and USFRS 
will provide the person with a copy of the USFRS XL waste MSDS, FPA and 
training module.
    (d) After successfully completing the activities identified in 
paragraph (c) of this section, USFRS will provide EPA with the name and 
such other information as the Agency may require to determine if a 
person may participate in the USFRS XL Project as a generator. USFRS 
will propose for inclusion into the USFRS XL Project only those 
person(s) whose wastes are compatible with the ion exchange resin 
process and canisters and whose storage area meets the standards in this 
subpart O. EPA's approval shall be effective within twenty one days of 
EPA's receipt of USFRS's written notice proposing to add a person to the 
USFRS XL Project unless EPA, within that time period, provides USFRS 
with a written notice rejecting such person.
    (e) After securing the approval of EPA, MPCA and the County 
Agencies, USFRS shall notify the person it proposed to add to the USFRS 
XL Project in writing that it is approved for participation in the USFRS 
XL Project. USFRS will assign to that person a unique client number and 
waste profile number for each waste stream approved for this XL project. 
USFRS will obtain from that person a copy of the signed USFRS XL waste 
FPA and a certification that it has read and agrees to follow the USFRS 
XL waste training module. USFRS shall also ensure that as part of this 
certification the approved customer identifies its contact person as 
required by 40 CFR 266.408(h). Upon request by EPA, USFRS will provide 
EPA with a copy of the signed documents or other documents it requests.
    (f) USFRS will accept USFRS XL waste only from those persons who 
have received the approval of EPA, MPCA and, as appropriate, the County 
Agencies and who have signed the USFRS XL Project FPA and the 
certification identified in paragraph (e) of this section. A person's 
participation in this USFRS XL Project is effective after EPA, MPCA and, 
as appropriate, the County Agency approve of them and on the date that 
USFRS receives the signed USFRS XL waste FPA and certification. At that 
time the person is a USFRS XL waste approved customer. A USFRS XL waste 
approved customer becomes a USFRS XL waste generator when it first 
generates or causes USFRS XL wastes to be regulated. A USFRS XL waste 
generator must handle all USFRS XL wastes generated after the effective 
date of it being added to the USFRS XL Project in accordance with the 
provisions of this subpart O. USFRS XL waste that is generated prior to 
this date is not subject to this subpart O and it must be handled 
according to the appropriate hazardous waste characterization for that 
waste, (e.g.. F006 and any other applicable waste code).
    (g) USFRS will require a USFRS XL waste approved customer and 
generator to update the USFRS XL waste application form prior to it 
adding to or modifying the waste streams or processes it identified on 
its initial USFRS XL waste application form. USFRS will notify EPA, MPCA 
and as appropriate, the County Agencies whenever a customer or generator 
notifies USFRS that it has or will add or modify waste streams or 
processes. EPA will notify USFRS if any further EPA approvals are 
required.



Sec. 266.403  Procedures for adding persons as transporters to EPA's USFRS XL Project.

    (a) Any person who wishes to participate in the USFRS XL Project as 
a transporter must obtain the approval of the EPA and the MPCA. The 
approval of the County Agencies is also required if that person's 
principal place of business is located in the counties of Anoka, Carver, 
Dakota, Hennepin, Ramsey, Scott or Washington. The procedures identified 
in this subpart are to be followed to obtain EPA approval to add a 
person as a transporter to the federal USFRS XL Project. USFRS and a 
proposed transporter must also comply with the procedures identified by 
the MPCA, and as appropriate the County Agencies. A person may not be 
added to the federal USFRS XL Project unless it has received the 
approval of

[[Page 63]]

EPA, MPCA and as appropriate the County Agencies.
    (b) USFRS is the only entity which may propose to EPA to add a 
person as a transporter to the USFRS XL Project.
    (c) USFRS and Pioneer Tank Lines are approved USFRS XL waste 
transporters. USFRS may propose to EPA to add other persons as USFRS XL 
waste transporters provided USFRS complies with the requirements of this 
section. USFRS will conduct a preliminary evaluation of any person who 
it proposes to add as a USFRS XL waste transporter. As part of that 
preliminary evaluation USFRS will ascertain whether the transporter has 
a valid EPA identification number, a valid Minnesota hazardous materials 
registration (``Minnesota registration'') and a satisfactory safety 
rating from USDOT within the last year.
    (d) After successfully completing the activities identified in 
paragraph (c) in this section USFRS will provide EPA with the name of 
the transporter, the unique USFRS client identification number for the 
transporter, the results of its preliminary evaluation identified in 
paragraph (c) and other information as EPA may require to determine if 
that person may participate in the USFRS XL Project. USFRS will propose 
for inclusion into the USFRS XL Project only those person(s) who have a 
satisfactory safety rating from USDOT. EPA's approval shall be effective 
within twenty one days of its receipt of USFRS's written notice 
proposing to add a person to the USFRS XL Project unless EPA, within 
that time period, provides USFRS with a written notice rejecting such 
person.
    (e) After receiving the approval of EPA, MPCA and as appropriate the 
County Agencies USFRS shall notify the person in writing that it is 
approved for participation in the USFRS XL Project. USFRS will obtain 
from that person a copy of the signed USFRS XL waste FPA and a 
certification that it has been trained by USFRS on the proper handling 
of USFRS XL wastes and understands its responsibilities under this 
subpart O.
    (f) USFRS will allow only USFRS XL approved transporters to 
transport USFRS XL wastes. A person's participation in this USFRS XL 
Project is effective after it receives the approval of EPA, MPCA and the 
County Agencies, as appropriate, and on the date that USFRS receives the 
signed USFRS XL waste FPA and certification. A USFRS XL waste approved 
transporter becomes a USFRS XL waste transporter when it first 
transports or accepts for transport USFRS XL waste.
    (g) USFRS will require a USFRS XL waste approved transporter or 
USFRS XL waste transporter to notify it of any change in its rating from 
USDOT, its Minnesota registration or its EPA identification number. 
USFRS will notify EPA, MPCA and, the appropriate County Agencies in 
writing of any such changes. EPA will notify USFRS in writing of any 
additional information or steps that may be required as a result of such 
changes.

this alternative treatment or disposal method only after its 
participation in this XL Project has been terminated.



Sec. 266.414  Termination of a USFRS XL waste approved customer's participation in the USFRS XL Project.

    The provisions in this section apply to a USFRS XL waste approved 
customer who has not yet generated USFRS XL waste. If a USFRS XL waste 
approved customer has generated or first caused to be regulated USFRS XL 
waste, then it is a USFRS XL waste generator and must comply with the 
termination provisions contained in Sec. 266.415. The following 
procedures are to be followed to terminate a person's participation in 
the federal USFRS XL Project. MPCA or the County Agencies

[[Page 68]]

may have their own procedures for terminating the participation of a 
person from their version of this federal USFRS XL Project. EPA is not 
bound by and will not follow those State or County procedures to 
terminate a person's continued participation in this USFRS XL Project. A 
USFRS waste approved customer's participation in the USFRS XL Project 
will terminate when the USFRS XL Project ends. It may terminate earlier 
either voluntarily, upon changes in ownership, upon notice by USFRS, 
EPA, MPCA or the appropriate County Agency.
    (a) Termination by the USFRS XL waste approved customer. A USFRS XL 
waste approved customer may terminate its participation in the USFRS XL 
Project at any time prior to its first generating USFRS XL wastes. The 
USFRS XL waste approved customer will provide 5 days written notice to 
USFRS, EPA, MPCA and as appropriate the County Agencies its desire to 
terminate its in the USFRS XL Project. No further action is required by 
such USFRS XL waste approved customer.
    (b) Change in ownership. A USFRS XL waste approved customer's 
participation will be automatically terminated upon a change in 
ownership. A USFRS XL waste approved customer must notify USFRS, EPA, 
MPCA and as appropriate the County Agencies within 5 days of a change in 
its ownership.
    (c) Termination by EPA, MPCA, County Agency or USFRS. If EPA or 
USFRS propose to terminate a USFRS XL waste approved customer they shall 
provide it with 5 days written notice. If MPCA or the County Agency 
propose to terminate such person they shall follow their own procedures 
and provide EPA and USFRS with the results of such proceedings. If MPCA 
or the County Agency terminates such person's participation in the 
federal USFRS XL Project, such person will be automatically terminated 
without further proceedings under this subpart O.



Sec. 266.415  Termination of a USFRS XL waste generator's participation in the USFRS XL Project.

    The procedures identified in this section are to be followed to 
terminate a waste generator's participation in the federal USFRS XL 
Project. MPCA or the County Agencies may have their own procedures for 
terminating the participation of a person from their version of this 
federal USFRS XL Project. EPA is not bound by and will not follow those 
State or County procedures to terminate a person's continued 
participation in this USFRS XL Project. A USFRS waste generator's 
participation in the USFRS XL Project may terminate when the USFRS XL 
Project ends. It may also terminate either voluntarily, upon changes in 
ownership, upon notice by USFRS, EPA, MPCA or the County Agency or at 
the termination of this subpart O.
    (a) Termination by the USFRS XL waste generator. The USFRS XL waste 
generator will provide 60 days written notice to USFRS, EPA, MPCA and 
the County Agencies of its desire to discontinue participation in the 
USFRS XL Project. Within the 60 days the USFRS XL waste generator shall 
accomplish the closure required by Sec. 266.412.
    (b) Termination by EPA, MPCA or the County Agency. EPA, MPCA or the 
County Agency may terminate a USFRS XL waste generator's participation. 
If EPA proposes to terminate such person's participation then it will 
provide the generator with written notice. EPA retains the right to 
terminate a USFRS XL waste generator's participation in the USFRS XL 
Project if the USFRS XL waste generator is in non-compliance with the 
requirements of this subpart. In the event of termination by EPA, EPA 
will provide USFRS, the USFRS XL waste generator, MPCA, and as 
appropriate the County Agencies with 15 days written notice of its 
intent to terminate a generator's continued participation in the USFRS 
XL Project. During this period, which commences on receipt of the notice 
to terminate by the generator, the generator will have the opportunity 
to come back into compliance or to provide a written explanation as to 
why it was not in compliance and how it intends to return to compliance. 
If, upon review of the written explanation EPA re-issues a written 
notice terminating the generator from this XL Project the generator 
shall close in accordance with Sec. 266.412. The USFRS XL waste

[[Page 69]]

generator shall complete the closure and comply with Sec. 266.412 within 
sixty days of EPA's re-issuance of the notice of termination. If MPCA or 
the County Agency propose to terminate such person they shall follow 
their own procedures and provide EPA and USFRS with the results of such 
proceedings. If MPCA or the County Agency terminates such person's 
participation in the federal USFRS XL Project, that person's 
participation will be automatically terminated without further 
proceedings under this subpart and such person must comply with the 
closure requirements contained in Sec. 266.412.
    (c) Termination by USFRS. USFRS may terminate a USFRS XL waste 
generator's participation in the USFRS XL Project only after providing 
60 days written notice to the generator, EPA, MPCA and the county 
agency. Within this time USFRS will arrange for the transport to its 
facility of the USFRS XL waste in storage. Additionally, USFRS will 
inspect the USFRS XL waste generator in accordance with Sec. 266.412(b).
    (d) Termination as a result of changes in ownership. A USFRS XL 
waste generator will provide written notice to USFRS, EPA, MPCA and as 
appropriate the County Agencies of a change in its ownership. It will 
provide such notice within 10 days of the change in ownership. Within 
the 60 days of the change in ownership the USFRS XL waste generator 
shall accomplish the closure required by Sec. 266.412 unless, within 
that time period, EPA has approved of the new owner and EPA has approved 
of any modifications the new owner proposes to the prior owner's closure 
responsibilities. If these approvals are not received within this time 
period the prior owner is still responsible for completing the closure 
within the 60 days.



Sec. 266.416  Termination of a USFRS XL waste approved transporter's participation in the USFRS XL Project.

    The provisions in this section apply to a USFRS XL waste approved 
transporter who has not transported or accepted for transport USFRS XL 
waste. If a USFRS XL waste approved transporter has transported or 
accepted for transport USFRS XL waste it is a USFRS XL waste transporter 
and must comply with the termination provisions contained in 
Sec. 266.417. The procedures identified in this section are to be 
followed to terminate a person's participation in the federal USFRS XL 
Project. MPCA or the County Agencies may have their own procedures for 
terminating the participation of a person from their version of this 
federal USFRS XL Project. EPA is not bound by and will not follow those 
State or County procedures to terminate a person's continued 
participation in this USFRS XL Project. A USFRS waste approved 
transporter's participation in the USFRS XL Project will terminate when 
the USFRS XL Project ends. It may also terminate earlier either 
voluntarily, upon changes in ownership, upon notice by USFRS, EPA, MPCA 
or the County Agency.
    (a) Termination by the USFRS XL waste approved transporter. A USFRS 
XL waste approved transporter may terminate its participation in the 
USFRS XL Project at any time prior to its first transporting or 
accepting for transport USFRS XL wastes. The USFRS XL waste approved 
transporter will provide 5 days written notice to USFRS, EPA, MPCA, and 
as appropriate the County Agencies of its desire to terminate its 
participation in the USFRS XL Project. No further action is required by 
such USFRS XL waste approved transporter.
    (b) Change in ownership. A USFRS XL waste approved transporter will 
be automatically terminated upon a change in ownership. A USFRS XL waste 
approved transporter must notify USFRS, EPA, MPCA and as appropriate the 
County Agencies within 5 days of a change in its ownership.
    (c) Termination by EPA, MPCA, the County Agencies or USFRS. EPA, 
MPCA, the County Agencies and USFRS may also terminate a USFRS XL waste 
approved transporter's participation in the USFRS XL. If EPA or USFRS 
propose such termination they will provide the transporter, each other, 
MPCA and the appropriate County Agencies with 5 days written notice.

Sec. 266.417  Termination of a USFRS XL waste transporter's participation in the USFRS XL Project.

    The procedures identified in this section are to be followed to 
terminate a person's participation in the federal USFRS XL Project. MPCA 
or the County Agencies may have their own procedures for terminating the 
participation of a person from their version of this federal USFRS XL 
Project. EPA is not bound by and will not follow those State or County 
procedures to terminate a person's continued participation in this USFRS 
XL Project. A USFRS waste transporter's participation in the USFRS XL 
Project will terminate when the USFRS XL Project ends. It may terminate 
earlier either voluntarily, upon a change in ownership of the 
transporter, upon notice by USFRS, EPA, MPCA or the County Agencies or 
at the termination of this subpart O.
    (a) Termination by the USFRS XL waste transporter--voluntary and 
changes in ownership. The USFRS XL waste transporter will provide 10 
days written notice to USFRS, EPA, MPCA and as appropriate the County 
Agencies of its desire to terminate its participation in the USFRS XL 
Project or of a change in ownership. Within 30 days of that notice the 
USFRS XL waste transporter will ensure that all of its shipments of 
USFRS XL waste are delivered to the USFRS facility.
    (b) Termination by EPA, MPCA or the County Agencies. EPA, MPCA or 
the County Agencies may terminate a USFRS XL waste transporter's 
participation in the USFRS XL Project. If MPCA or the County Agency 
propose to terminate such person they shall follow their own procedures 
and provide EPA and USFRS with the results of such proceedings. If MPCA 
or the County Agency does terminate such person's participation, such 
person's participation in the federal USFRS XL Project will be 
automatically terminated without further proceedings under this subpart 
and the transporter shall ensure that all shipments of XL waste are 
delivered to the USFRS facility within 30 days of notice of termination. 
If EPA proposes to terminate a transporter's participation in the USFRS 
XL Project EPA will provide such person, MPCA, the County Agency and 
USFRS with a 30 days written notice prior to terminating such person's 
participation in the USFRS XL Project. EPA retains the right to 
terminate a USFRS XL waste transporters participation in the USFRS XL 
Project if the USFRS XL waste transporter is not in compliance with the 
requirements of this subpart O. During this period, which commences on 
receipt of the notice by the transporter, the USFRS XL waste transporter 
will have the opportunity to come back into compliance or to provide a 
written explanation as to why it was not in compliance and how it 
intends to return to compliance. If, upon review of the written 
explanation EPA re-issues a written notice terminating the USFRS XL 
waste transporter from this XL Project the USFRS XL waste transporter 
shall ensure that all shipments of USFRS XL waste are delivered to the 
USFRS facility within 30 days of such re-issued notice.
    (c) Termination by USFRS. USFRS may terminate a USFRS XL waste 
transporter's participation in the USFRS XL Project only after providing 
30 days written notice to the transporter, EPA, MPCA and as appropriate 
the County Agencies. Within this time USFRS will arrange for the 
transport to its facility of the USFRS XL waste in the possession of the 
USFRS XL waste transporter.
    (d) Change in ownership. A USFRS XL waste transporter will be 
automatically terminated upon a change in ownership. A USFRS XL waste 
transporter must notify USFRS, EPA, the County Agencies and MPCA within 
5 days of a change in its ownership. Within 30 days of its notice of 
change of ownership the USFRS XL waste transporter shall ensure that all 
shipments of USFRS XL waste in its possession are delivered to the USFRS 
facility.



Sec. 266.418  Termination of USFRS' participation in this XL Project.

    The procedures identified in this section are to be followed to 
terminate USFRS' participation in the federal USFRS XL Project. MPCA or 
the County Agencies may have their own procedures for terminating USFRS' 
participation from their version of this

[[Page 71]]

federal USFRS XL Project. EPA is not bound by and will not follow those 
State or County procedures to terminate USFRS' continued participation 
in this USFRS XL Project. USFRS' participation in the USFRS XL Project 
will terminate when the USFRS XL project ends. It may terminate earlier 
either voluntarily, upon a change in ownership of USFRS, upon notice of 
EPA, MPCA or as appropriate the County Agency. The USFRS XL Waste 
Project is terminated if USFRS' participation is terminated, unless 
there is a change in ownership of USFRS and EPA, MPCA and the County 
Agencies have approved the new owner's continuation in the USFRS XL 
project as provided in paragraph (b) of this section. In such an 
instance USFRS must supply EPA, MPCA and the County Agencies with a 
proposed schedule for transitioning all USFRS XL Project participants to 
compliance with the RCRA requirements within 120 days of a notice to 
terminate pursuant to this section.
    (a) USFRS' termination of its participation in this XL Project--
voluntary termination. USFRS will provide written notice to all USFRS XL 
Project participants (e.g., USFRS XL waste approved customers and 
approved transporters, USFRS XL waste generators and transporters), EPA, 
MPCA and the County Agencies of its desire to terminate its 
participation in the USFRS XL Project (``voluntary termination'') USFRS 
will provide its notice of voluntary termination 120 days prior to the 
date it proposes to terminate this XL Project. Within this 120 days 
USFRS will arrange for the transition of it and the USFRS XL waste 
Project participants to return to compliance with the RCRA requirements. 
During this time all USFRS XL Project participants will complete all 
closure activities required by Sec. 266.412.
    (b) Termination as a result in a change of ownership of USFRS. USFRS 
will provide written notice to EPA, MPCA and the County Agencies of any 
change in ownership of USFRS. USFRS will provide this notice 90 days 
prior to a change in ownership. At that time, if the new owner wishes to 
continue the USFRS XL waste Project it will submit any revisions it 
proposes to make to the FPA to add itself to the USFRS XL waste project. 
If EPA and the new owner are able to agree upon and sign the proposed 
revisions to the FPA within that time frame then the new owner may 
continue the USFRS XL Project. If an agreement and signature is not 
obtained within that time frame, the USFRS XL Project will be 
terminated. If it does not obtain that approval or does not wish to 
continue the USFRS XL Project then USFRS will arrange for the transition 
of all USFRS XL waste Project participants to return to compliance with 
the RCRA requirements within 120 days of the change in ownership. All 
USFRS XL waste Project participants will complete all closure activities 
required by Sec. 266.412.
    (c) EPA or MPCA termination of the USFRS XL Project. EPA or MPCA may 
terminate this XL Project after providing written notice to USFRS. EPA 
retains the right to terminate this XL Project if:
    (1) USFRS is in non-compliance with the requirements of this 
subpart;
    (2) This Project does not provide superior environmental benefit; 
or,
    (3) If there is repeated non-compliance by USFRS XL waste generators 
or transporters.
    (d) In the event of termination by EPA, EPA will provide USFRS, MPCA 
and the County Agencies with 30 days written notice of its intent to 
terminate this XL Project. During this period, which commences on 
receipt of the notice by USFRS, USFRS will have the opportunity to come 
back into compliance, to provide a written explanation as to why it was 
not in compliance and how it intends to return to compliance or 
otherwise respond to the reasons for EPA's proposed termination. If, 
upon review of the written explanation EPA re-issues a written notice 
terminating this XL Project then USFRS shall submit to EPA within 30 
days of its receipt of the re-issued notice its plan for transitioning 
all USFRS XL waste Project participants to compliance with the RCRA 
requirements. This transition plan shall contain a proposed schedule 
which accomplishes compliance with RCRA within 120 days of EPA's re-
issued written notice.

Sec. 266.419  USFRS recordkeeping and reporting requirements.

    (a) Annual reporting. USFRS will provide an annual report, on 
October 1, on all USFRS XL wastes. It will provide the information 
separately for each USFRS XL waste generator. The annual report, at a 
minimum, will include:
    (1) An identification of each USFRS XL waste generator who sent 
USFRS XL wastes to USFRS; the quantity of XL waste that USFRS received 
from each USFRS XL waste generator during the calendar year and a 
certification by USFRS that those USFRS XL wastes were treated and 
recycled at USFRS in accordance with this subpart O;
    (2) The amount of water recycled by the generators, the pretreatment 
chemicals and energy the generators did not use as a result of 
participating in this USFRS XL Project, the amount of water discharged 
to the local POTW before and during this project, the amount of sludge 
recovered by USFRS before and during this project, the amount of sludge 
recovered as opposed to disposed of by a generator (if the generator 
disposed of the sludge prior to participating in this project), the 
quantity of material (ion exchange resins, filters, other wastewater 
treatment sludge, residues) collected from each facility (monthly), the 
frequency of resin canister and filter replacement in terms of process 
volume, the constituents in the material (ion exchange resins, filters, 
other wastewater treatment sludge, residues) collected at each facility 
(e.g., recoverable metals, contaminants/non-recoverable materials); and 
constituents in the material (ion exchange resins, filters, other 
wastewater treatment sludge, residues) disposed by each facility (e.g., 
contaminants/non-recoverable material).
    (3) Quantity of material (ion exchange resins, filters, other 
wastewater treatment sludge, residues) to be processed from the XL waste 
at the USFRS Roseville facility, quantity of the metals recovered from 
the XL waste at the USFRS Roseville facility, the constituents of the 
recovered material (ion exchange resins, filters, other wastewater 
treatment sludge, residues from the XL waste), quantity and constituents 
of the non-recoverable material from the XL waste (ion exchange resins, 
filters, other wastewater treatment sludge, residues), and how it was 
disposed of; and
    (4) The quantity of each metal recovered at each metals reclamation 
facility it uses for this Project.
    (b) Quarterly reporting. USFRS will submit a quarterly report to 
EPA, MPCA and the County Agencies on October 1, January 1, April 1 and 
July 1 which will include:
    (1) Sufficient information for EPA to determine the amount of 
superior environmental benefit resulting from this project. That report 
will, at a minimum, contain information which includes, but is not 
limited to: the volume of water and waste collected and recycled; the 
amount of metals recycled; the volume of recycled material sold to 
others; data regarding the management of the ion exchange canisters and 
filter containers; the constituents of the sludge; and information 
regarding how the sludge and residues are managed;
    (2) Financial information related to the costs and savings realized 
as a result of implementation of this project.
    (i) USFRS will collect baseline and XL costs. The baseline costs 
shall be calculated using two scenarios:
    (A) Typical expenses (including any hazardous waste taxes) of the 
generator (prior to the XL Project) for pretreating and disposing 
effluent wastewater under the applicable Clean Water Act requirements 
and the costs for manifesting, transporting and disposing of F006 
sludges; and
    (B) Typical expenses of the generator that would be incurred if 
waste were recycled in compliance with RCRA and requirements for 
manifesting and transportation of those hazardous wastes (including tax 
obligations under both scenarios).
    (ii) The XL costs will include the costs to the generator for 
completing the Transportation Tracking Document, the transportation 
costs for XL wastes, the generator's cost to install the ion exchange 
canisters and filter containers, any other costs the generator incurs 
such as cleaning up any spills, payment of hazardous waste

[[Page 73]]

taxes, etc., the cost to USFRS of metals reclamation off-site (including 
costs associated with transportation or disposal). USFRS will compare 
the baseline costs to the XL costs and provide an analysis of whether 
the project is resulting in cost savings for generators and which 
aspects of the XL Project produce any savings. USFRS will also submit 
any of the information required in paragraphs (b)(2)(i)(A) and (B) of 
this section upon request by EPA, MPCA or the County Agency;
    (3) A list of all USFRS XL Waste Approved Customers and Generators. 
USFRS shall include on that list the customer and generator's name, a 
summary of the results of the USFRS waste characterization of the 
customer and generator's waste stream(s) and process(es), the customer's 
and generator's process waste streams approved for participation in the 
USFRS XL Waste Project, the unique client number USFRS has assigned to 
the customer and generator and its waste stream, the date of USFRS 
notice to EPA and MPCA proposing to add the customer and generator to 
the USFRS XL Project; the date on which USFRS notified the customer that 
it is approved for participation in this USFRS XL Project; and the date 
USFRS received the signed FPA and certification from the customer or 
generator. The list shall also contain the date of any notice of 
termination, and if there is a termination, the date on which USFRS 
recovered all of its USFRS XL wastes from the generator and the date 
USFRS conducted its visual evaluation of the condition of the USFRS XL 
waste storage areas and notice of compliance with Sec. 266.412. USFRS 
will update its waste customer and generator list when new customers and 
generators have been approved by EPA, MPCA and the County Agencies or 
when a customer or generator has been terminated from this XL Project; 
and
    (4) A list of all USFRS XL Waste Approved Transporters. USFRS shall 
include on this list the transporter's unique USFRS client number, the 
transporter's name, and if available, EPA identification number and its 
Minnesota registration number, the date of USFRS notice to EPA and MPCA 
proposing to add the transporter to the USFRS XL Project; the date on 
which USFRS notified the transporter that it is a USFRS XL Waste 
Approved Transporter; and the date on which it received the signed USFRS 
XL waste FPA and certification. The list shall also contain the date of 
any notice of termination, and if there is a termination, the date on 
which USFRS recovered all of its USFRS XL wastes from the transporter. 
This USFRS XL waste transporter list may be modified upon approval of 
EPA and MPCA.

     Section 2.0 Performance Specifications for Continuous Emission 
                           Monitoring Systems

  2.l Performance Specifications for Continuous Emission Monitoring of 
  Carbon Monoxide and Oxygen for Incinerators, Boilers, and Industrial 
                    Furnaces Burning Hazardous Waste

                    2.1.1 Applicability and Principle

    2.1.1.1 Applicability. These performance specifications apply to 
carbon monoxide (CO) and oxygen (O2) continuous emission 
monitoring systems (CEMSs) installed on incinerators, boilers, and 
industrial furnaces burning hazardous waste. The specifications include 
procedures which are intended to be used to evaluate the acceptability 
of the CEMS at the time of its installation or whenever specified in 
regulations or permits. The procedures are not designed to evaluate CEMS 
performance over an extended period of time. The source owner or 
operator is responsible for the proper calibration, maintenance, and 
operation of the CEMS at all times.
    2.1.1.2 Principle. Installation and measurement location 
specifications, performance and equipment specifications, test and data 
reduction procedures, and brief quality assurance guidelines are 
included in the specifications. Calibration drift, relative accuracy, 
calibration error, and response time tests are conducted to determine 
conformance of the CEMS with the specifications.

                            2.1.2 Definitions

    2.1.2.1 Continuous Emission Monitoring System (CEMS). A continuous 
monitor is one in which the sample to be analyzed passes the measurement 
section of the analyzer without interruption, and which evaluates the 
detector response to the sample at least once each 15 seconds and 
computes and records the results at least every 60 seconds. A CEMS 
consists of all the equipment used to acquire data and includes the 
sample extraction and transport hardware, the analyzer(s), and the data 
recording/processing hardware and software.
    2.1.2.2 Monitoring System Types. The specifications require CEMSs 
capable of accepting calibration gases. Alternative system designs may 
be used if approved by the Regional Administrator. There are two basic 
types of monitoring systems: extractive and in-situ.
    2.1.2.2.1 Extractive. Systems that use a pump or other mechanical, 
pneumatic, or hydraulic means to draw a sample of the stack or flue gas 
and convey it to a remotely located analyzer.
    2.1.2.2.2 In-situ. Systems that perform an analysis without removing 
a sample from the stack. Point in-situ analyzers place the sensing or 
detecting element directly in the flue gas stream. Cross-stack in-situ 
analyzers measure the parameter of interest by placing a source beam on 
one side of the stack and the detector (in single-pass instruments) or a 
retroreflector (in double-pass instruments) on the other side, and 
measuring the parameter of interest (e.g., CO) by the attenuation of the 
beam by the gas in its path.
    2.1.2.3 Instrument Measurement Range. The difference between the 
minimum and maximum concentration that can be measured by a specific 
instrument. The minimum is often stated or assumed to be zero and the 
range expressed only as the maximum.
    2.1.2.4 Span or Span Value. Full scale instrument measurement range.
    2.1.2.5 Calibration Drift (CD). The difference in the CEMS output 
readings from the established reference value after a stated period of 
operation during which no unscheduled maintenance, repair, or adjustment 
takes place. A CD test is performed to demonstrate the stability of the 
CEMS calibration over time.
    2.1.2.6 Response Time. The time interval between the start of a step 
change in the system input (e.g., change of calibration gas) and the 
time when the data recorder displays 95 percent of the final value.
    2.1.2.7 Accuracy. A measure of agreement between a measured value 
and an accepted or true value, expressed as the percentage difference 
between the true and measured values relative to the true value. For 
these performance specifications, accuracy is checked by conducting a 
calibration error (CE) test and a relative accuracy (RA) test. Certain 
facilities, such as those using solid waste or batch-fed processes, may 
observe long periods of almost no CO emissions with brief, high-level CO 
emission spikes. These facilities, as well as facilities whose CO 
emissions never exceed 5-10 ppm, may need to be exempted from the RA 
requirement because the RA test procedure cannot ensure acquisition of 
meaningful test results under these conditions. An alternative procedure 
for accuracy determination is described in section 2.1.9.
    2.1.2.8 Calibration Error (CE). The difference between the 
concentration indicated by the CEMS and the known concentration of the 
cylinder gas. A CE test procedure is performed to document the accuracy 
and linearity of the monitoring equipment over the entire measurement 
range.

[[Page 87]]

    2.1.2.9 Relative Accuracy (RA). A comparison of the CEMS response to 
a value measured by a performance test method (PTM). The PA test is used 
to validate the calibration technique and verify the ability of the CEMS 
to provide representative and accurate measurements.
    2.1.2.10 Performance Test Method (PTM). The sampling and analysis 
procedure used to obtain reference measurements for comparison to CEMS 
measurements. The applicable test methods are Method 10, 10A, or 10B 
(for the determination of CO) and Method 3 or 3A (for the determination 
of 02). These methods are found in 40 CFR part 60, appendix 
A.
    2.1.2.11 Performance Specification Test (PST) Period. The period 
during which CD, CE, response time, and RA tests are conducted.
    2.1.2.12 Centroidal Area. A concentric area that is geometrically 
similar to the stack or duct cross section and is no greater than 1 
percent of the stack or duct cross-sectional area.

       2.1.3 Installation and Measurement Location Specifications

    2.1.3.1 CEMS Installation and Measurement Locations. The CEMS shall 
be installed in a location in which measurements representative of the 
source's emissions can be obtained. The optimum location of the sample 
interface for the CEMS is determined by a number of factors, including 
ease of access for calibration and maintenance, the degree to which 
sample conditioning will be required, the degree to which it represents 
total emissions, and the degree to which it represents the combustion 
situation in the firebox. The location should be as free from in-leakage 
influences as possible and reasonably free from severe flow 
disturbances. The sample location should be at least two equivalent duct 
diameters downstream from the nearest control device, point of pollutant 
generation, or other point at which a change in the pollutant 
concentration or emission rate occurs and at least 0.5 diameter upstream 
from the exhaust or control device. The equivalent duct diameter is 
calculated as per 40 CFR part 60, appendix A, method 1, section 2.1. If 
these criteria are not achievable or if the location is otherwise less 
than optimum, the possibility of stratification should be checked as 
described in Section 2.1.3.3 to determine whether the location would 
cause failure of the relative accuracy test.
    2.1.3.1.1 For extractive or point in-situ CEMSs, the measurement 
point should be within or centrally located over the centroidal area of 
the stack or duct cross section.
    2.1.3.1.2 For cross-stack CEMSs, the effective measurement path 
should (1) have at least 70 percent of the path within the inner 50 
percent of the stack or duct cross-sectional area or (2) be centrally 
located over any part of the centroidal area.
    2.1.3.1.3 Both the CO and O2 monitors should be installed 
at the same general location. If this is not possible, they may be 
installed at different locations if the effluent gases at both sample 
locations are not stratified and there is no in-leakage of air between 
sampling locations.
    2.1.3.2 Performance Test Method (PTM) Measurement Location and 
Traverse Points.
    2.1.3.2.1 Select an accessible PTM measurement point at least two 
equivalent diameters downstream from the nearest control device, the 
point of CO generation, or other point at which a change in the CO 
concentration may occur, and at least a half equivalent diameter 
upstream from the effluent exhaust or control device. When pollutant 
concentration changes are due solely to diluent leakage (e.g., air 
heater leakages) and CO and O2 are simultaneously measured at 
the same location, one half diameter may be used in place of two 
equivalent diameters. The CEMS and PTM locations need not be the same.
    2.1.3.2.2 Select traverse points that ensure acquisition of 
representative samples over the stack or duct cross section. At a 
minimum, establish a measurement line that passes through the centroidal 
area in the direction of any expected stratification. If this line 
interferes with the CEMS measurements, displace the line up to 30 cm (or 
5 percent of the equivalent diameter of the cross section, whichever is 
less) from the centroidal area. Locate three traverse points at 17, 50, 
and 83 percent of the measurement line. If the measurement line is no 
longer than 2.4 meters and pollutant stratification is not expected, the 
tester may choose to locate the three traverse points on the line at 
0.4, 1.2, and 2.0 meters from the stack or duct wall. This option must 
not be used at a site located within eight equivalent diameters 
downstream of a flow disturbance. The tester may select other traverse 
points, provided that they can be shown to the satisfaction of the 
Administrator to provide a representative sample over the stack or duct 
cross-section. Conduct all necessary PTM tests within 3 cm of the 
selected traverse points. Sampling must not be performed within 3 cm of 
the duct or stack inner wall.
    2.1.3.3 Stratification Test Procedure. Stratification is defined as 
a difference in excess of 10 percent between the average concentration 
in the duct or stack and the concentration at any point more than 1.0 
meter from the duct or stack wall. To determine whether effluent 
stratification exists, a dual probe system should be used to determine 
the average effluent concentration while measurements at each traverse 
point are being made. One probe, located at the stack

[[Page 88]]

or duct centroid, is used as a stationary reference point to indicate 
the change in effluent concentration over time. The second probe is used 
for sampling at the traverse points specified in method 1, appendix A, 
40 CFR part 60. The monitoring system samples sequentially at the 
reference and traverse points throughout the testing period for five 
minutes at each point.
    2.1.4 CEMS Performance and Equipment Specifications
    Table 2.1-1 summarizes the performance specifications for the CEMSs. 
Two sets of standards for CO are given; one for low-range and another 
for high-range measurements. The high-range specifications relate to 
measurement and quantification of short duration high concentration 
peaks, while the low-range specifications relate to the overall average 
operating condition of the burning device. The dual-range specifications 
can be met by using (1) one analyzer for each range, (2) a dual range 
unit, or (3) a single measurement range instrument capable of meeting 
both specifications with a single unit. Adjustments cannot be made to 
the analyzer between determinations of low- and high-level accuracy 
within the single measurement range. In the second case, when the 
concentration exceeds the span of the lower range, the data acquisition 
system recorder shall switch to the high range automatically.
    2.1.4.1 CEMS Span Value. In order to measure high and low 
concentrations with the same or similar degree of accuracy, the maximum 
ranges (span values) are specified for low and high range analyzers. The 
span values are listed in Table 2.1-2. Tier I and Tier II format 
definitions are established in 40 CFR part 266, subpart H.

    2.1.4.2 Daily Calibration Gas Values. The owner or operator must 
choose calibration gas concentrations (or calibration filters for in-
situ systems) that include zero and high-level calibration values for 
the daily calibration checks. For a single measurement range monitor, 
three CO calibration gas concentrations (or calibration filters for in-
situ systems) shall be used, i.e., the zero and high-level 
concentrations of the low-range CO analyzer and the high-level 
concentration of the high-range CO analyzer.
    2.1.4.2.1 The zero level for the CO or O2 analyzer may be 
between zero and 20 percent of the span value, e.g., 0-40 ppm for low-
range CO analyzer, 0-600 ppm for the high-range CO analyzer, and 0-5 
percent for the O2 analyzer (for Tier I).
    2.1.4.2.2 The high-level concentration for the CO or O2 
analyzer shall be between 50 and 90 percent of the span value, i.e., 
100-180 ppm for the low-range CO analyzer, 1500-2700 ppm for the high-
range CO analyzer, and 12.5-22.5 percent O2 for the 
O2 analyzer.
    2.1.4.3 Data Recorder Scale. The strip chart recorder, computer, or 
digital recorder must be capable of recording all readings within the 
CEMS's measurement range and shall have a resolution of 0.5 percent of 
span value, i.e., 1 ppm CO for low-range CO analyzer, 15 ppm CO for 
high-range CO analyzer, and 0.1 percent O2 for the 
O2 analyzer.
    2.1.4.4 Response Time. The response time for the CO or O2 
monitor shall not exceed 2 minutes to achieve 95 percent of the final 
stable value.
    2.1.4.5 Calibration Drift. The CEMS must allow the determination of 
CD at the zero and high-level values. The CD must be determined 
separately for CO and O2 monitors in terms of concentration. 
The CO CEMS calibration response must not drift or deviate from the 
reference value of the calibration gas (or calibration filters for in-
situ systems) by more than 3 percent of the span value after each 24-
hour period of the 7-day test, i.e., 6 ppm CO for the low-range analyzer 
(Tier I) and 90 ppm for the high-range analyzer, at both zero and high 
levels. The O2 monitor calibration response must not drift or 
deviate from the reference value by more than 0.5 percent O2 
at both zero and high levels.

[[Page 89]]

    2.l.4.6 Relative Accuracy. The result of the PA test of the CO CEMS 
(which incorporates the O2 monitor) must be no greater than 
10 percent of the mean value of the PTM results or must be within 10 ppm 
CO of the PTM results, whichever is less restrictive. The ppm CO 
concentration shall be corrected to 7 percent O2 before 
calculating the RA.
    2.1.4.7 Calibration Error. The mean difference between the CEMS and 
reference values at all three test points (see Table 2.1-3) must be no 
greater than 5 percent of span value for CO monitors (i.e., 10 ppm CO 
for low range Tier I CO analyzers and 150 ppm CO for high range CO 
analyzers) and 0.5 percent for O2 analyzers.
    2.1.4.8 Measurement and Recording Frequency. The sample to be 
analyzed shall pass through the measurement section of the analyzer 
without interruption. The detector shall measure the sample 
concentration at least once every 15 seconds. An average emission rate 
shall be computed and recorded at least once every 60 seconds.
    2.1.4.9 Hourly Rolling Average Calculation. The CEMS shall calculate 
every minute an hourly rolling average, which is the arithmetic mean of 
the 60 most recent 1-minute average values.
    2.1.4.10 Retest. If the CEMS produces results within the specified 
criteria, the test is successful. If the CEMS does not meet one or more 
of the criteria, the necessary corrections must be made and the 
performance tests repeated.

                           2.1.5 Test Periods

    2.1.5.1 Pretest Preparation Period. Install the CEMS, prepare the 
PTM test site according to the specifications in section 2.1.3, and 
prepare the CEMS for operation and calibration according to the 
manufacturer's written instructions. A pretest conditioning period 
similar to that of the 7-day CD test is recommended to verify the 
operational status of the CEMS.
    2.1.5.2 Calibration Drift Test Period. While the facility is 
operating under normal conditions, determine the CD at 24-hour intervals 
for seven consecutive days according to the procedure given in section 
2.1.6.1. All CD determinations must be made following a 24-hour period 
during which no unscheduled maintenance, repair, or adjustment takes 
place. If the combustion unit is taken out of service during the test 
period, record the onset and duration of the downtime and continue the 
calibration drift test when the unit resumes operation.
    2.1.5.3 Relative Accuracy Test Period. Conduct the RA test according 
to the procedure in section 2.1.6.4 while the facility is operating 
under normal conditions. RA testing for CO and O2 shall be 
conducted simultaneously so that the results can be calculated for CO 
corrected to 7 percent O2. The RA test shall be conducted 
during the CD test period. It is emphasized that during the CD test 
period, no adjustments or repairs may be made to the CEMS other than 
routine calibration adjustments performed immediately following the 
daily CD determination.
    2.1.5.4 Calibration Error Test and Response Time Test Periods. 
Conduct the CE and response time tests during the CD test period.

             2.1.6 Performance Specification Test Procedures

    2.1.6.1 Calibration Drift Test.
    2.1.6.1.1 Sampling Strategy. Conduct the CD test for all monitors at 
24-hour intervals for seven consecutive days using calibration gases at 
the two (or three, if applicable) concentration levels specified in 
section 2.1.4.2. Introduce the calibration gases into the sampling 
system as close to the sampling probe outlet as practical. The gas shall 
pass through all filters, scrubbers, conditioners, and other CEMS 
components used during normal sampling. If periodic automatic or manual 
adjustments are made to the CEMS zero and calibration settings, conduct 
the CD test immediately before these adjustments, or conduct it in such 
a way that the CD can be determined. Record the CEMS response and 
subtract this value from the reference (calibration gas) value. To meet 
the specification, none of the differences shall exceed the limits 
specified in Table 2.1-1.
    2.1.6.1.2 Calculations. Summarize the results on a data sheet. An 
example is shown in Figure 2.1-1. Calculate the differences between the 
CEMS responses and the reference values.
    2.1.6.2 Response Time. Check the entire CEMS including sample 
extraction and transport, sample conditioning, gas analyses, and the 
data recording.
    2.1.6.2.1 Introduce zero gas into the system. For extractive 
systems, introduce the calibration gases at the probe as near to the 
sample location as possible. For in-situ system, introduce the zero gas 
at a point such that all components active in the analysis are tested. 
When the system output has stabilized (no change greater than 1 percent 
of full scale for 30 seconds), switch to monitor stack effluent and wait 
for a stable value. Record the time (upscale response time) required to 
reach 95 percent of the final stable value.
    2.1.6.2.2 Next, introduce a high-level calibration gas and repeat 
the above procedure. Repeat the entire procedure three times and 
determine the mean upscale and downscale response times. The longer of 
the two means is the system response time.
    2.1.6.3 Calibration Error Test Procedure.
    2.1.6.3.1 Sampling Strategy. Challenge each monitor (both low- and 
high-range CO and O2) with zero gas and EPA Protocol 1

cylinder gases at three measurement points within the ranges specified 
in Table 2.1-3.

    2.1.6.3.1.1 If a single measurement range is used, the calibration 
gases used in the daily CD checks (if they are Protocol 1 cylinder gases 
and meet the criteria in section 2.1.6.3.1) may be used for determining 
CE.
    2.1.6.3.1.2 Operate each monitor in its normal sampling mode as 
nearly as possible. The calibration gas shall be injected into the 
sample system as close to the sampling probe outlet as practical and 
should pass through all CEMS components used during

[[Page 91]]

normal sampling. Challenge the CEMS three non-consecutive times at each 
measurement point and record the responses. The duration of each gas 
injection should be sufficient to ensure that the CEMS surfaces are 
conditioned.
    2.1.6.3.2 Calculations. Summarize the results on a data sheet. An 
example data sheet is shown in Figure 2.1-2. Average the differences 
between the instrument response and the certified cylinder gas value for 
each gas. Calculate three CE results (five CE results for a single-range 
CO CEMS) according to Equation 5 (section 2.1.7.5). No confidence 
coefficient is used in CE calculations.
    2.1.6.4 Relative Accuracy Test Procedure.
    2.1.6.4.1 Sampling Strategy for PTM tests. Conduct the PTM tests in 
such a way that they will yield measurements representative of the 
emissions from the source and can be correlated to the CEMS data. 
Although it is preferable to conduct the CO, diluent, and moisture (if 
needed) simultaneously, moisture measurements that are taken within a 
60-minute period which includes the simultaneous CO and O2 
measurements may be used to calculate the dry CO concentration.
    Note: At times, CEMS RA tests may be conducted during incinerator 
performance tests. In these cases, PTM results obtained during CEMS RA 
tests may be used to determine compliance with incinerator emissions 
limits as long as the source and test conditions are consistent with the 
applicable regulations.

    2.1.6.4.2 Performance Test Methods.
    2.1.6.4.2.1 Unless otherwise specified in the regulations, method 3 
or 3A and method 10, 10A, or 10B (40 CFR part 60, appendix A) are the 
test methods for O2 and CO, respectively. Make a sample 
traverse of at least 21 minutes, sampling for 7 minutes at each of three 
traverse points (see section 3.2).

[[Page 92]]

    2.1.6.4.2.2 When the installed CEMS uses a nondispersive infrared 
(NDIR) analyzer, method 10 shall use the alternative interference trap 
specified in section 10.1 of the method. An option, which may be 
approved by the Administrator in certain cases, would allow the test to 
be conducted using method 10 without the interference trap. Under this 
option, a laboratory interference test is performed for the analyzer 
prior to the field test. The laboratory interference test includes the 
analysis of SO2, NO, and CO2 calibration gases 
over the range of expected effluent concentrations. Acceptable 
performance is indicated if the CO analyzer response to each of the 
gases is less than 1 percent of the applicable measurement range of the 
analyzer.
    2.1.6.4.3 Number of PTM Tests. Conduct a minimum of nine sets of all 
necessary PTM tests. If more than nine sets are conducted, a maximum of 
three sets may be rejected at the tester's discretion. The total number 
of sets used to determine the RA must be greater than or equal to nine. 
All data, including the rejected data, must be reported.
    2.1.6.4.4 Correlation of PTM and CEMS Data. The time and duration of 
each PTM test run and the CEMS response time should be considered in 
correlating the data. Use the CEMS final output (the one used for 
reporting) to determine an integrated average CO concentration for each 
PTM test run. Confirm that the pair of results are on a consistent 
moisture and O2 concentration basis. Each integrated CEMS 
value should then be compared against the corresponding average PTM 
value. If the CO concentration measured by the CEMS is normalized to a 
specified diluent concentration, the PTM results shall be normalized to 
the same value.
    2.1.6.4.5 Calculations. Summarize the results on a data sheet. 
Calculate the mean of the PTM values and calculate the arithmetic 
differences between the PTM and the CEMS data sets. The mean of the 
differences, standard deviation, confidence coefficient, and CEMS RA 
should be calculated using Equations 1 through 4.

calculations, CEMS data records, and cylinder gas or reference material 
certifications.

[[Page 93]]

                       2.1.9 Alternative Procedure

    2.1.9.1 Alternative RA Procedure Rationale. Under some operating 
conditions, it may not be possible to obtain meaningful results using 
the RA test procedure. This includes conditions where consistent, very 
low CO emissions or low CO emissions interrupted periodically by short 
duration, high level spikes are observed. It may be appropriate in these 
circumstances to waive the PTM RA test and substitute the following 
procedure.
    2.1.9.2 Alternative RA Procedure. Conduct a complete CEMS status 
check following the manufacturer's written instructions. The check 
should include operation of the light source, signal receiver, timing 
mechanism functions, data acquisition and data reduction functions, data 
recorders, mechanically operated functions (mirror movements, 
calibration gas valve operations, etc.), sample filters, sample line 
heaters, moisture traps, and other related functions of the CEMS, as 
applicable. All parts of the CEMS must be functioning properly before 
the RA requirement can be waived. The instruments must also have 
successfully passed the CE and CD requirements of the performance 
specifications. Substitution of the alternative procedure requires 
approval of the Regional Administrator.

                      2.1.10 Quality Assurance (QA)

    Proper calibration, maintenance, and operation of the CEMS is the 
responsibility of the owner or operator. The owner or operator must 
establish a QA program to evaluate and monitor CEMS performance. As a 
minimum, the QA program must include:
    2.1.10.1 A daily calibration check for each monitor. The calibration 
must be adjusted if the check indicates the instrument's CD exceeds the 
specification established in section 2.1.4.5. The gases shall be 
injected as close to the probe as possible to provide a check of the 
entire sampling system. If an alternative calibration procedure is 
desired (e.g., direct injections or gas cells), subject to Administrator 
approval, the adequacy of this alternative procedure may be demonstrated 
during the initial 7-day CD test. Periodic comparisons of the two 
procedures are suggested.
    2.1.10.2 A daily system audit. The audit must include a review of 
the calibration check data, an inspection of the recording system, an 
inspection of the control panel warning lights, and an inspection of the 
sample transport and interface system (e.g., flowmeters, filters), as 
appropriate.
    2.1.10.3 A quarterly calibration error (CE) test. Quarterly RA tests 
may be substituted for the CE test when approved by the Director on a 
case-by-case basis.
    2.1.10.4 An annual performance specification test.

  2.2 Performance Specifications for Continuous Emission Monitoring of 
Hydrocarbons for Incinerators, Boilers, and Industrial Furnaces Burning 
                             Hazardous Waste

                    2.2.1 Applicability and Principle

    2.2.1.1 Applicability. These performance specifications apply to 
hydrocarbon (HC) continuous emission monitoring systems (CEMSs) 
installed on incinerators, boilers, and industrial furnaces burning 
hazardous waste. The specifications include procedures which are 
intended to be used to evaluate the acceptability of the CEMS at the 
time of its installation or whenever specified in regulations or 
permits. The procedures are not designed to evaluate CEMS performance 
over an extended period of time. The source owner or operator is 
responsible for the proper calibration, maintenance, and operation of 
the CEMS at all times.
    2.2.1.2 Principle. A gas sample is extracted from the source through 
a heated sample line and heated filter (except as provided by section 
2.2.10) to a flame ionization detector (FID). Results are reported as 
volume concentration equivalents of propane. Installation and 
measurement location specifications, performance and equipment 
specifications, test and data reduction procedures, and brief quality 
assurance guidelines

[[Page 94]]

are included in the specifications. Calibration drift, calibration 
error, and response time tests are conducted to determine conformance of 
the CEMS with the specifications.

                            2.2.2 Definitions

    2.2.2.1 Continuous Emission Monitoring System (CEMS). The total 
equipment used to acquire data, which includes sample extraction and 
transport hardware, analyzer, data recording and processing hardware, 
and software. The system consists of the following major subsystems:
    2.2.2.1.1 Sample Interface. That portion of the system that is used 
for one or more of the following: Sample acquisition, sample 
transportation, sample conditioning, or protection of the analyzer from 
the effects of the stack effluent.
    2.2.2.1.2 Organic Analyzer. That portion of the system that senses 
organic concentration and generates an output proportional to the gas 
concentration.
    2.2.2.1.3 Data Recorder. That portion of the system that records a 
permanent record of the measurement values. The data recorder may 
include automatic data reduction capabilities.
    2.2.2.2 Instrument Measurement Range. The difference between the 
minimum and maximum concentration that can be measured by a specific 
instrument. The minimum is often stated or assumed to be zero and the 
range expressed only as the maximum.
    2.2.2.3 Span or Span Value. Full scale instrument measurement range.
    2.2.2.4 Calibration Gas. A known concentration of a gas in an 
appropriate diluent gas.
    2.2.2.5 Calibration Drift (CD). The difference in the CEMS output 
readings from the established reference value after a stated period of 
operation during which no unscheduled maintenance, repair, or adjustment 
takes place. A CD test is performed to demonstrate the stability of the 
CEMS calibration over time.
    2.2.2.6 Response Time. The time interval between the start of a step 
change in the system input (e.g., change of calibration gas) and the 
time when the data recorder displays 95 percent of the final value.
    2.2.2.7 Accuracy. A measurement of agreement between a measured 
value and an accepted or true value, expressed as the percentage 
difference between the true and measured values relative to the true 
value. For these performance specifications, accuracy is checked by 
conducting a calibration error (CE) test.
    2.2.2.8 Calibration Error (CE). The difference between the 
concentration indicated by the CEMS and the known concentration of the 
cylinder gas. A CE test procedure is performed to document the accuracy 
and linearity of the monitoring equipment over the entire measurement 
range.
    2.2.2.9 Performance Specification Test (PST) Period. The period 
during which CD, CE, and response time tests are conducted.
    2.2.2.10 Centroidal Area. A concentric area that is geometrically 
similar to the stack or duct cross section and is no greater than 1 
percent of the stack or duct cross-sectional area.

       2.2.3 Installation and Measurement Location Specifications

    2.2.3.1 CEMS Installation and Measurement Locations. The CEMS shall 
be installed in a location in which measurements representative of the 
source's emissions can be obtained. The optimum location of the sample 
interface for the CEMS is determined by a number of factors, including 
ease of access for calibration and maintenance, the degree to which 
sample conditioning will be required, the degree to which it represents 
total emissions, and the degree to which it represents the combustion 
situation in the firebox. The location should be as free from in-leakage 
influences as possible and reasonably free from severe flow 
disturbances. The sample location should be at least two equivalent duct 
diameters downstream from the nearest control device, point of pollutant 
generation, or other point at which a change in the pollutant 
concentration or emission rate occurs and at least 0.5 diameter upstream 
from the exhaust or control device. The equivalent duct diameter is 
calculated as per 40 CFR part 60, appendix A, method 1, section 2.1. If 
these criteria are not achievable or if the location is otherwise less 
than optimum, the possibility of stratification should be investigated 
as described in section 2.2.3.2. The measurement point shall be within 
the centroidal area of the stack or duct cross section.
    2.2.3.2 Stratification Test Procedure. Stratification is defined as 
a difference in excess of 10 percent between the average concentration 
in the duct or stack and the concentration at any point more than 1.0 
meter from the duct or stack wall. To determine whether effluent 
stratification exists, a dual probe system should be used to determine 
the average effluent concentration while measurements at each traverse 
point are being made. One probe, located at the stack or duct centroid, 
is used as a stationary reference point to indicate the change in 
effluent concentration over time. The second probe is used for sampling 
at the traverse points specified in 40 CFR part 60 appendix A, method 1. 
The monitoring system samples sequentially at the reference and traverse 
points throughout the testing period for five minutes at each point.
    2.2.4 CEMS Performance and Equipment Specifications

[[Page 95]]

    If this method is applied in highly explosive areas, caution and 
care shall be exercised in choice of equipment and installation.
    2.2.4.1 Flame Ionization Detector (FID) Analyzer. A heated FID 
analyzer capable of meeting or exceeding the requirements of these 
specifications. Heated systems shall maintain the temperature of the 
sample gas between 150 [deg]C (300 [deg]F) and 175 [deg]C (350 [deg]F) 
throughout the system. This requires all system components such as the 
probe, calibration valve, filter, sample lines, pump, and the FID to be 
kept heated at all times such that no moisture is condensed out of the 
system.
    Note: As specified in the regulations, unheated HC CEMs may be 
considered an acceptable interim alternative monitoring technique. For 
additional notes, see section 2.2.10. The essential components of the 
measurement system are described below:
    2.2.4.1.1 Sample Probe. Stainless steel, or equivalent, to collect a 
gas sample from the centroidal area of the stack cross-section.
    2.2.4.1.2 Sample Line. Stainless steel or Teflon tubing to transport 
the sample to the analyzer.
    Note: Mention of trade names or specific products does not 
constitute endorsement by the Environmental Protection Agency.
    2.2.4.1.3 Calibration Valve Assembly. A heated three-way valve 
assembly to direct the zero and calibration gases to the analyzer is 
recommended. Other methods, such as quick-connect lines, to route 
calibration gas to the analyzers are applicable.
    2.2.4.1.4 Particulate Filter. An in-stack or out-of-stack sintered 
stainless steel filter is recommended if exhaust gas particulate loading 
is significant. An out-of-stack filter must be heated.
    2.2.4.1.5 Fuel. The fuel specified by the manufacturer (e.g., 40 
percent hydrogen/60 percent helium, 40 percent hydrogen/60 percent 
nitrogen gas mixtures, or pure hydrogen) should be used.
    2.2.4.1.6 Zero Gas. High purity air with less than 0.1 parts per 
million by volume (ppm) HC as methane or carbon equivalent or less than 
0.1 percent of the span value, whichever is greater.
    2.2.4.1.7 Calibration Gases. Appropriate concentrations of propane 
gas (in air or nitrogen). Preparation of the calibration gases should be 
done according to the procedures in EPA Protocol 1. In addition, the 
manufacturer of the cylinder gas should provide a recommended shelf life 
for each calibration gas cylinder over which the concentration does not 
change by more than [plusmn]2 percent from the certified value.
    2.2.4.2 CEMS Span Value. 100 ppm propane.
    2.2.4.3 Daily Calibration Gas Values. The owner or operator must 
choose calibration gas concentrations that include zero and high-level 
calibration values.
    2.2.4.3.1 The zero level may be between 0 and 20 ppm (zero and 20 
percent of the span value).
    2.2.4.3.2 The high-level concentration shall be between 50 and 90 
ppm (50 and 90 percent of the span value).
    2.2.4.4 Data Recorder Scale. The strip chart recorder, computer, or 
digital recorder must be capable of recording all readings within the 
CEMS's measurement range and shall have a resolution of 0.5 ppm (0.5 
percent of span value).
    2.2.4.5 Response Time. The response time for the CEMS must not 
exceed 2 minutes to achieve 95 percent of the final stable value.
    2.2.4.6 Calibration Drift. The CEMS must allow the determination of 
CD at the zero and high-level values. The CEMS calibration response must 
not differ by more than [plusmn]3 ppm ([plusmn]3 percent of the span 
value) after each 24-hour period of the 7-day test at both zero and high 
levels.
    2.2.4.7 Calibration Error. The mean difference between the CEMS and 
reference values at all three test points listed below shall be no 
greater than 5 ppm ([plusmn]5 percent of the span value).
    2.2.4.7.1 Zero Level. Zero to 20 ppm (0 to 20 percent of span 
value).
    2.2.4.7.2 Mid-Level. 30 to 40 ppm (30 to 40 percent of span value).
    2.2.4.7.3 High-Level. 70 to 80 ppm (70 to 80 percent of span value).
    2.2.4.8 Measurement and Recording Frequency. The sample to be 
analyzed shall pass through the measurement section of the analyzer 
without interruption. The detector shall measure the sample 
concentration at least once every 15 seconds. An average emission rate 
shall be computed and recorded at least once every 60 seconds.
    2.2.4.9 Hourly Rolling Average Calculation. The CEMS shall calculate 
every minute an hourly rolling average, which is the arithmetic mean of 
the 60 most recent 1-minute average values.
    2.2.4.10 Retest. If the CEMS produces results within the specified 
criteria, the test is successful. If the CEMS does not meet one or more 
of the criteria, necessary corrections must be made and the performance 
tests repeated.
    2.2.5 Performance Specification Test (PST) Periods
    2.2.5.1 Pretest Preparation Period. Install the CEMS, prepare the 
PTM test site according to the specifications in section 2.2.3, and 
prepare the CEMS for operation and calibration according to the 
manufacturer's written instructions. A pretest conditioning period 
similar to that of the 7-day CD test is recommended to verify the 
operational status of the CEMS.
    2.2.5.2 Calibration Drift Test Period. While the facility is 
operating under normal

[[Page 96]]

conditions, determine the magnitude of the CD at 24-hour intervals for 
seven consecutive days according to the procedure given in section 
2.2.6.1. All CD determinations must be made following a 24-hour period 
during which no unscheduled maintenance, repair, or adjustment takes 
place. If the combustion unit is taken out of service during the test 
period, record the onset and duration of the downtime and continue the 
CD test when the unit resumes operation.
    2.2.5.3 Calibration Error Test and Response Time Test Periods. 
Conduct the CE and response time tests during the CD test period.
    2.2.6 Performance Specification Test Procedures
    2.2.6.1 Calibration Drift Test.
    2.2.6.1.1 Sampling Strategy. Conduct the CD test at 24-hour 
intervals for seven consecutive days using calibration gases at the two 
daily concentration levels specified in section 2.2.4.3. Introduce the 
two calibration gases into the sampling system as close to the sampling 
probe outlet as practical. The gas shall pass through all CEM components 
used during normal sampling. If periodic automatic or manual adjustments 
are made to the CEMS zero and calibration settings, conduct the CD test 
immediately before these adjustments, or conduct it in such a way that 
the CD can be determined. Record the CEMS response and subtract this 
value from the reference (calibration gas) value. To meet the 
specification, none of the differences shall exceed 3 ppm.
    2.2.6.1.2 Calculations. Summarize the results on a data sheet. An 
example is shown in Figure 2.2-1. Calculate the differences between the 
CEMS responses and the reference values.
    2.2.6.2 Response Time. The entire system including sample extraction 
and transport, sample conditioning, gas analyses, and the data recording 
is checked with this procedure.
    2.2.6.2.1 Introduce the calibration gases at the probe as near to 
the sample location as possible. Introduce the zero gas into the system. 
When the system output has stabilized (no change greater than 1 percent 
of full scale for 30 sec), switch to monitor stack effluent and wait for 
a stable value. Record the time (upscale response time) required to 
reach 95 percent of the final stable value.
    2.2.6.2.2 Next, introduce a high-level calibration gas and repeat 
the above procedure. Repeat the entire procedure three times and 
determine the mean upscale and downscale response times. The longer of 
the two means is the system response time.
    2.2.6.3 Calibration Error Test Procedure.
    2.2.6.3.1 Sampling Strategy. Challenge the CEMS with zero gas and 
EPA Protocol 1 cylinder gases at measurement points within the ranges 
specified in section 2.2.4.7.
    2.2.6.3.1.1 The daily calibration gases, if Protocol 1, may be used 
for this test.

                      2.2.9 Quality Assurance (QA)

    Proper calibration, maintenance, and operation of the CEMS is the 
responsibility of the owner or operator. The owner or operator must 
establish a QA program to evaluate and monitor CEMS performance. As a 
minimum, the QA program must include:
    2.2.9.1 A daily calibration check for each monitor. The calibration 
must be adjusted if the check indicates the instrument's CD exceeds 3 
ppm. The gases shall be injected as close to the probe as possible to 
provide a check of the entire sampling system. If an alternative 
calibration procedure is desired (e.g., direct injections or gas cells), 
subject to Administrator approval, the adequacy of this alternative 
procedure may be demonstrated during the initial 7-day CD test. Periodic 
comparisons of the two procedures are suggested.
    2.2.9.2 A daily system audit. The audit must include a review of the 
calibration

[[Page 100]]

check data, an inspection of the recording system, an inspection of the 
control panel warning lights, and an inspection of the sample transport 
and interface system (e.g., flowmeters, filters), as appropriate.
    2.2.9.3 A quarterly CE test. Quarterly RA tests may be substituted 
for the CE test when approved by the Director on a case-by-case basis.
    2.2.9.4 An annual performance specification test.

                2.2.10 Alternative Measurement Technique

    The regulations allow gas conditioning systems to be used In 
conjunction with unheated HC CEMs during an interim period. This gas 
conditioning may include cooling to not less than 40 [deg] F and the use 
of condensate traps to reduce the moisture content of sample gas 
entering the FID to less than 2 percent. The gas conditioning system, 
however, must not allow the sample gas to bubble through the condensate 
as this would remove water soluble organic compounds. All components 
upstream of the conditioning system should be heated as described in 
section 2.2.4 to minimize operating and maintenance problems.

    Note: The sampling and analytical methods to the BIF manual are

Chemical Methods,'' EPA Publication SW-846, as incorporated by reference 
in Sec. 260.11 of this chapter.

    Section 4.0 Procedure for Estimating the Toxicity Equivalence of 
         Chlorinated Dibenco-P-Dioxin and Dibenzofuran Congeners

    PCDDs and PCDFs must be determined using the method given in section 
3.4 of this document. In this method, individual congeners or homologues 
\1\ are measured and then summed to yield a total PCDD/PCDF value. No 
toxicity factors are specified in the method to compute risks from such 
emissions.
---------------------------------------------------------------------------

    \1\ The term ``congener'' refers to any one particular member of the 
same chemical family; e.g., there are 75 congeners of chlorinated 
dibenzo-p-dioxins. The term ``homologue'' refers to a group of 
structurally related chemicals that have the same degree of 
chlorination. For example, there are eight homologues of CDs, 
monochlorinated through octachlorinated. Dibenzo-p-dioxins and 
dibenzofurans that are chlorinated at the 2,3,7, and 8 positions are 
denoted as ``2378'' congeners, except when 2,3,7,8-TCDD is uniquely 
referred to: e.g., 1,2,3,7,8-PeCDF and 2,3,4,7,8-PeCDF are both referred 
to as ``2378-PeCDFs.''
---------------------------------------------------------------------------

    For the purpose of estimating risks posed by emissions from boilers 
and industrial furnaces, however, specific congeners and homologues must 
be measured using the specified method and then multiplied by the 
assigned toxicity equivalence factors (TEFs), using procedures described 
in ``Interim Procedures for Estimating Risks Associated with Exposures 
to Mixtures of Chlorinated Dibenzo-p-Dioxins and Dibenzofurans (CDDs and 
CDFs) and 1989 Update,'' EPA/625/3-89/016, March 1989. The resulting 
2,3,7,8-TCDD equivalents value is used in the subsequent risk 
calculations and modeling efforts as discussed in the BIF final rule.
    The procedure for calculating the 2,3,7,8-TCDD equivalent is as 
follows:
    1. Using method 23, determine the concentrations of 2,7,3,8-
congeners of various PCDDs and PCDFs in the sample.
    2. Multiply the congener concentrations in the sample by the TEF 
listed in Table 4.0-1 to express the congener concentrations in terms of 
2,3,7,8-TCDD equivalent. Note that congeners not chlorinated at 2,3,7, 
and 8 positions have a zero toxicity factor in this table.
    3. Add the products obtained in step 2, to obtain the total 2,3,7,8-
TCDD equivalent in the sample.
    Sample calculations are provided in EPA document No. EPA/625/3-89/
016, March 1989, which can be obtained from the EPA, ORD Publications 
Office, Cincinnati, Ohio (Phone no. 513-569-7562).

 Section 5.0 Hazardous Waste Combustion Air Quality Screening Procedure

    The HWCAQSP is a combined calculation/reference table approach for 
conservatively estimating short-term and annual average facility impacts 
for stack emissions. The procedure is based on extensive short-term 
modeling of 11 generic source types and on a set of adjustment factors 
for estimating annual average concentrations from short-term 
concentrations. Facility impacts may be determined based on the selected 
worst-case stack or on multiple stacks, in which the impacts from each 
stack are estimated separately and then added to produce the total 
facility impact.
    This procedure is most useful for facilities with multiple stacks, 
large source-to-property boundary distances, and complex terrain between 
1 and 5 km from the facility. To ensure a sufficient degree of 
conservatism, the HWCAQSP may not be used if any of the five screening 
procedure limitations listed below are true:
    [sbull] The facility is located in a narrow valley less than 1 km 
wide;
    [sbull] The facility has a stack taller than 20 m and is located 
such that the terrain rises to the stack height within 1 km of the 
facility;
    [sbull] The facility has a stack taller than 20 m and is located 
within 5 km of the shoreline of a large body of water;
    [sbull] The facility property line is within 200 m of the stack and 
the physical stack height is less than 10 m; or
    [sbull] On-site receptors are of concern, and stack height is less 
than 10 m.
    If any of these criteria are met or the Director determines that 
this procedure is not appropriate, then detailed site-specific modeling 
or modeling using the ``Screening Procedures for Estimating the Air 
Quality Impact of Stationary Sources,'' EPA -450/4-88-010, Office of Air 
Quality Planning and Standards, August 1988, is required. Detailed site-
specific dispersion modeling must conform to the EPA ``Guidance on Air 
Quality Models (Revised)'', EPA 450/2-78-027R, Office of Air Quality 
Planning and Standards, Research Triangle Park, North Carolina, July 
1986. This document provides guidance on both the proper selection and 
regulatory application of air quality models.

                              Introduction

    The Hazardous Waste Combustion Air Quality Screening Procedure 
(HWCAQSP) (also referred to hereafter as ``the screening procedure'' or 
``the procedure'') provides a quick, easy method for estimating maximum 
(hourly) and annual average ambient air impacts associated with the 
combustion of hazardous waste. The methodology is conservative in nature 
and estimates dispersion coefficients \1\ based on facility-specific 
information.
---------------------------------------------------------------------------

    \1\ The term dispersion coefficient refers to the change in ambient 
air concentration ([mu]g/m\3\) resulting from a source with an emission 
rate of 1 g/sec.
---------------------------------------------------------------------------

    The screening procedure can be used to determine emissions limits at 
sites where the nearest meteorological (STAR) station is not 
representative of the meteorology at the site. If the screen shows that 
emissions from the site are adequately protective, then the need to 
collect site-specific meteorological data can be eliminated.
    The screening procedure is generally most helpful for facilities 
meeting one or more of the following conditions:
    [sbull] Multiple stacks with substantially different release 
specifications (e.g., stack heights differ by 50 percent, 
exit temperatures differ by 50 [deg]K, or the exit flow rates 
differ by more than a factor of 2),
    [sbull] Terrain located between 1 km and 5 km from the site 
increases in elevation by more than the physical height of the shortest 
stack (i.e., the facility is located in complex terrain), or
    [sbull] Significant distance between the facility's stacks and the 
site boundary [guidance on determining whether a distance is 
``significant'' is provided in Step 6(B) of the procedure].
    Steps 1 through 9 of the screening procedure present a simplified 
method for determining emissions based on the use of the ``worst-case'' 
stack. If the simplified method shows that desired feed rates result in 
emissions that exceed allowable limits for one or more pollutants, a 
refined analysis to examine the emissions from each stack can be 
conducted. This multiple-stack method is presented in Step 10.

[[Page 102]]

    The steps involved in screening methodology are as follows:

Step 1. Define Source Characteristics
Step 2. Determine the Applicability of the Screening Procedure
Step 3. Select the Worst-Case Stack
Step 4. Verify Good Engineering Practice (GEP) Criteria
Step 5. Determine the Effective Stack Height and Terrain-Adjusted 
Effective Stack Height
Step 6. Classify the Site as Urban or Rural
Step 7. Determine Maximum Dispersion Coefficients
Step 8. Estimate Maximum Ambient Air Concentrations
Step 9. Determine Compliance With Regulatory Limits
---------------------------------------------------------------------------

    \2\ Worksheet space is provided for three stacks. If the facility 
has additional stacks, copy the form and revise stack identification 
numbers for 4, 5, etc.
---------------------------------------------------------------------------

Step 10. Multiple Stack Method

                  Step 1: Define Source Characteristics

    Provide the following source data: \2\

------------------------------------------------------------------------
                                       Stack No.   Stack No.   Stack No.
             Stack Data:                   1           2           3
------------------------------------------------------------------------
Physical stack height (m)...........   --------    --------    --------
Exhaust temperature ([deg]K)........   --------    --------    --------
Flow rate (m\3\/sec)................   --------    --------    --------
------------------------------------------------------------------------

                       Nearby Building Dimensions

    Consider all buildings within five building heights or five maximum 
projected widths of the stack(s). For the building with the greatest 
height, fill in the spaces below.
Building Height (m)_____________________________________________________
Maximum projected building width (m)____________________________________

                           Nearby Terrain Data

    Determine maximum terrain rise for the following three distance 
ranges from the facility (not required if the highest stack is less than 
10 m in height):

      --------(m)              --------(m)              --------(m)
        0-0.5 km                 0-2.5 km                 0-5 km
 

Distance from facility to nearest shoreline (km)________________________
Valley width (km)_______________________________________________________

     Step 2: Determine the Applicability of the Screening Procedure

    Fill in the following data:

 
                                                       Yes         No
 
Is the facility in a valley < km in width?........     ------     ------
Is the terrain rise within 1 km of the facility        ------     ------
 greater than the physical stack height of the
 tallest stack? (Only applies to stacks [le]20
 meters in height)................................
Is the distance to the nearest shoreline <5 km?        ------     ------
 (Only applies to facilities with stacks [le]20
 meters in height)................................
For the building listed in Step 1, is the closest      ------     ------
 property boundary <5 times the building height or
 <5 times the maximum projected building width?
 (Only applies to facilities with a stack height
 <2.5 times the building height)..................
 

    If the answer is ``no'' to all the preceding questions, then the 
HWCAQSP is acceptable. If the answer to any question is ``yes'', the 
procedure is not acceptable.

                   Step 3: Select the Worst-Case Stack

    If the facility has several stacks, a worst-case stack must be 
chosen to conservatively represent release conditions at the facility. 
Follow the steps below to identify the worst-case stack.
    Apply the following equation to each stack:
K=HVT

where:

K=an arbitrary parameter accounting for the relative influence of the 
          stack height and plume rise.
H=Physical stack height (m)
V=Flow rate (m\3\/sec)
T=Exhaust temperature ([deg]K)
    Complete the following table to compute the ``K'' value for each 
stack:

----------------------------------------------------------------------------------------------------------------
                                 Stack height        Flow rate (m\3\/         Exit temp

    Select the stack with the lowest ``K'' value. This is the worst-case 
stack that will be used for Steps 4 through 9.

    Worst-Case Stack is identified as Stack No. ------

[[Page 103]]

         Step 4: Verify Good Engineering Practice (GEP) Criteria

    Confirm that the selected worst-case stack meets Good Engineering 
Practice (GEP) criteria. The stack height to be used in the subsequent 
steps of this procedure must not be greater than the maximum GEP. 
Maximum and minimum GEP stack heights are defined as follows:
CEP (minimum)=H+(1.5xL)
GEP (maximum)=greater of 65 m or H+(1.5xL)
where:

H=height of the building selected in Step 1 measured from ground level 
          elevation at the base of the stack
L=the lesser dimension of the height or projected width of the building 
          selected in Step 1
    Record the following data for the worst-case stack:
Stack height (m)=----------
H(m)=----------
L(m)=----------

    Then compute the following:
GEP (minimum) (m)=----------
GEP (maximum) (m)=----------

    [sbull] If the physical height of the worst-case stack exceeds the 
maximum GEP, then use the maximum GEP stack height for the subsequent 
steps of this analysis;
    [sbull] If the physical height of the worst-case stack is less than 
the minimum GEP, then use generic source number 11 as the selected 
source for further analysis and proceed directly to Step 6;
    [sbull] If the physical height of the worst-case stack is between 
the minimum and maximum GEP, then use the actual physical stack height 
for the subsequent steps of this analysis.

 Step 5: Determine the Effective Stack Height and the Terrain-Adjusted 
                     Effective Stack Height (TAESH)

    The effective stack height is an important factor in dispersion 
modeling. The effective stack height is the physical height of the stack 
plus plume rise. As specified in Step 4, the stack height used to 
estimate the effective stack height must not exceed GEP requirements. 
Plume rise is a function of the stack exit gas temperature and flow 
rate.
    In this analysis, the effective stack height is used to select the 
generic source that represents the dispersion characteristics of the 
facility. For facilities located in flat terrain and for all facilities 
with worst-case stacks less than or equal to 10 meters in height, 
generic source numbers are selected strictly on the basis of effective 
stack height. In all other cases, the effective stack height is further 
adjusted to take into account the terrain rise near the facility. This 
``terrain-adjusted effective stack height'' (TAESH) is then used to 
select the generic source number that represents the dispersion 
characteristics of the facility. Follow the steps below to identify the 
effective stack height, the TAESH (where applicable), and the 
corresponding generic source number.
    (A) Go to Table 5.0-1 and find the plume rise value corresponding to 
the stack temperature and exit flow rate for the worst-case stack 
determined in Step 3.
Plume rise=--------(m)
    (B) Add the plume rise to the GEP stack height of the worst-case 
stack determined in Steps 3 and 4.

 
                                                         Effective stack
     GEP stack height (m)       +   Plume rise (m)    =     height (m)
 
           --------             +      --------       =      --------
 

    (C) Go to the first column of Table 5.0-2 and identify the range of 
effective stack heights that includes the effective stack height 
estimated in Step 5(B). Record the generic source number that 
corresponds to this range.
Generic source number=----------
    (D) If the source is located in flat terrain \3\, or if the generic 
source number identified in Step 5(C) above is 1 or 11 (regardless of 
terrain classification), use the generic source number determined in 
Step 5(C) and proceed directly to Step 6. Otherwise, continue to Step 
5(E).
---------------------------------------------------------------------------

    \3\ The terrain is considered flat and terrain adjustment factors 
are not used if the maximum terrain rise within 5 km of the facility 
(see Step 1) is less than 10 percent of the physical stack height of the 
worst-case stack.
---------------------------------------------------------------------------

    (E) For those situations where the conditions in Step 5(D) do not 
apply, the effective stack height must be adjusted for terrain. The 
TAESH for each distance range is computed by subtracting the terrain 
rise within the distance range from the effective stack height.\4\
---------------------------------------------------------------------------

    \4\ Refer to Step 1 for terrain adjustment data. Note that the 
distance from the source to the outer radii of each range is used. For 
example, for the range 0.5-2.5 km, the maximum terrain rise 
in the range 0.0-2.5 km is used.

    Step 6: Classify the Site as Urban or Rural
    (A) Classify the land use near the facility as either urban or rural 
by determining the percentage of urban land use types (as defined in 
Table 3; for further guidance see the footnoted references) that fall 
within 3 km of the facility.\5\
---------------------------------------------------------------------------

    \5\ The delineation of urban and rural areas, can be difficult for 
the residential-type areas listed in Table 5.0-3. The degree of 
resolution in Table 5.0-3 for residential areas often cannot be 
identified without conducting site area inspections. This process can 
require extensive analysis, which, for many applications, can be greatly 
streamlined without sacrificing confidence in selecting the appropriate 
urban or rural classification. The fundamental simplifying assumption is 
based on the premise that many applications will have clear-cut urban/
rural designations, i.e., most will be in rural settings that can be 
definitively characterized through a review of aerial photographs, 
zoning maps, or U.S. Geological Survey topographical maps.

Method Used to Estimate Percent      Visual             Planimeter
 Urban Land Use:
                                     ------             ------
Estimated Percentages..............  Urban              Rural
                                     ------             ------
 

    If the urban land use percentage is less than or equal to 30 percent 
based on a visual estimate, or 50 percent based on a planimeter, the 
local land use is considered rural. Otherwise, the local land use is 
considered urban.

Classification.....................  Urban              Rural

    (B) Based on the TAESH and the urban/rural classification of 
surrounding land use, use the following table to determine the threshold 
distance between any stack and the nearest facility boundary.

------------------------------------------------------------------------

                                                           Urban   Rural

------------------------------------------------------------------------

    Record the following information:
Threshold distance from the table
(m): ----
Minimum distance from any stack to property boundary (m): ----

    If the minimum distance between any stack and the nearest facility 
boundary is greater than the threshold distance, the surrounding buffer 
distance is considered significant and the facility is likely to benefit 
from use of the HWCAQSP relative to the Tier I and II limits (see 
discussion of benefits from using HWCAQSP in Introduction section).

            Step 7: Determine Maximum Dispersion Coefficients

    (A) Determine maximum average hourly dispersion coefficients. Based 
on the results of Step 6(A), select either Table 5.0-4 (urban) or Table 
5.0-5 (rural) to determine the maximum average hourly dispersion 
coefficient.\6\ For flat terrain [defined in Step 5(D)] and for all 
sites with generic source numbers 1 or 11, use Step 7(A) (1). For 
rolling or complex terrain (excluding generic sources numbers 1 and 11), 
use Step 7(A) (2).
---------------------------------------------------------------------------

    \6\ For the distance range 6 to 20 kilometers, generic source number 
1 is used to conservatively represent the maximum dispersion 
coefficient.
---------------------------------------------------------------------------

    (1) Search down the appropriate generic source number column [based 
on Step 5(C)], beginning at the minimum fenceline distance listed in 
Step 6(B).\7\ Record the maximum average hourly dispersion coefficient 
encountered.
---------------------------------------------------------------------------

    \7\ Exclude all distances that are closer to the facility than the 
property boundary. For example, if the actual distance to the nearest 
property boundary is 265 meters, begin at the 300 meter distance in 
Tables 5.0-4 and 5.0-5.

fenceline distance listed in Step 6(B). Note that different columns may 
be used for each of the three distance ranges if there is a need for 
terrain adjustment. Record the maximum dispersion coefficient for each 
generic source number.

    (B) Determine annual/hourly ratio for rural analysis. The maximum 
average annual dispersion coefficient is approximated by multiplying the 
maximum hourly dispersion coefficient (identified in Step 7(A) by the 
appropriate ratio selection from Table 5.0-6. The generic source 
number(s) [from Steps 5(C) or 5(E)], urban/rural designation (from Step 
6), and the terrain type are used to select the appropriate scaling 
factor. Use the noncomplex terrain designation for all sources located 
in flat terrain, for all sources where the physical stack height of the 
worst-case stack is less than or equal to 10 m, for all sources where 
the worst-case stack is less than the minimum GEP, and for those sources 
where all of the TAESH values in Step 5(E) are greater than zero. Use 
the complex terrain designation in all other situations.
    (C) Determine maximum average annual dispersion coefficient. The 
maximum average annual dispersion coefficient is determined by 
multiplying the maximum hourly dispersion coefficient (Step 7(A)) by its 
corresponding annual/hourly ratio (Step 7(B)).

Step 8: Estimate Maximum Ambient Air Concentrations--see procedures 
          prescribed in subpart H of 40 CFR part 266.
Step 9: Determine Compliance with Regulatory Limits--see procedures 
          prescribed in subpart H of 40 CFR part 266.
Step 10: Multiple Stack Method (Optional)
    This option is a special case procedure that may be helpful when (1) 
the facility exceeded the regulatory limits for one or more pollutants, 
as detailed in Step 9, and (2) the facility has multiple stacks with 
substantially different emission rates and effective release heights. 
Only those pollutants that fail the Step 9 screening limits need to be 
addressed in this exercise.
    This procedure assesses the environmental impacts from each stack 
and then sums the results to estimate total impacts. This option is 
conceptually the same as the basic approach (Steps 1 through 9) and does 
not involve complex calculations. However, it is more time-consuming and 
is recommended only if the basic approach fails to meet the risk 
criteria. The procedure is outlined below.
    (A) Compute effective stack heights for each stack.\8\
---------------------------------------------------------------------------

    \8\ Follow the procedure outlined in Step 4 of the basic screening 
procedure to determine the GEP for each stack. If a stack's physical 
height exceeds the maximum GEP, use the maximum GEP values. If a stack's 
physical height is less than the minimum GEP, use generic source number 
11 in the subsequent steps of this analysis. Follow the procedure in 
Steps 5(A) and 5(B) to determine the effective height of each stack.

Add an additional page if more than three stacks are involved. Circle the maximum and minimum effective stack heights.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    (B) Determine if this multiple-stack screening procedure will likely 
produce less conservative results than the procedure in Steps 1 through 
9. To do this, compute the ratio of maximum-to-minimum effective stack 
height:

[[Page 111]]


    If the above ratio is greater than 1.25, proceed with the remaining 
steps. Otherwise, this option is less likely to significantly reduce the 
degree of conservatism in the screening method.
    (C) Determine if terrain adjustment is needed and select generic 
source numbers. Select the shortest stack height and maximum terrain 
rise out to 5 km from Step 1 and determine if the facility is in flat 
terrain.
Shortest stack height (m)=______________________________________________
Maximum terrain rise in meters out to 5 km=_____________________________
[GRAPHIC] [TIFF OMITTED] TC06NO91.013

    If the value above is greater than 10 percent, the terrain is 
considered nonflat; proceed to Step 10(D). If the ratio is less than or 
equal to 10 percent, the terrain is considered flat. Identify the 
generic source numbers based on effective stack heights computed in Step 
10(A). Refer to Table 5.0-2 provided earlier to identify generic source 
numbers. Record the generic source numbers identified and proceed to 
Step 10(F).

    1. Compute the TAESH for all remaining stacks using the following 
equation:
HE-TR=TAESH
where:
    HE=effective stack height (m)
    TR=maximum terrain rise for each distance range (m)
    TAESH=terrain-adjusted effective stack height (m)

                          Use the Table Below To Calculate the TAESH for Each Stack \9\
----------------------------------------------------------------------------------------------------------------
                                                                       Stack No.

                                     ---------------------------------------------------------------------------
                                       HE  -   TR   =  TAESH   HE  -   TR   =    TAESH     HE  -   TR   =  TAESH

2...................................  ...  -  ...   =  .....  ...  -  ...   =  .........  ...  -  ...   =  .....
3...................................  ...  -  ...   =  .....  ...  -  ...   =  .........  ...  -  ...   =  .....
----------------------------------------------------------------------------------------------------------------
\9\ Refer to Step 1 for terrain adjustment data. Note that the distance from the source to the outer radii of
  each range is used. For example, for the range 0.5-2.5 km, the maximum terrain rise in the range
  0.0-2.5 km is used.

    For those stacks where the terrain rise within a distance range is 
greater than the effective stack height (i.e., HE-TR is less than zero), 
the TAESH for that distance range is set equal to zero, and generic 
source number 1 should be used for that distance range for all 
subsequent distance ranges. Additionally, for all stacks with a physical 
stack height of less than or equal to 10 meters, use generic source 
number 1 for all distance ranges.\10\ For the remaining stacks, proceed 
to Step 10(D)(2).
---------------------------------------------------------------------------

    \10\ This applies to all stacks less than or equal to 10 meters 
regardless of the terrain classification.
---------------------------------------------------------------------------

    2. For the remaining stacks, refer to Table 5.0-2 and, for each 
distance range, identify the generic source number that includes the 
TAESH. Use the values obtained from Steps 10(D)(1) and 10(D)(2) to 
complete the following summary worksheet;

    (E) Identify maximum average hourly dispersion coefficients. Based 
on the land use classification of the site (e.g., urban or rural), use 
either Table 5.0-4 or Table 5.0-5 to determine the appropriate 
dispersion coefficient for each distance range for each stack. Begin at 
the minimum fenceline distance indicated in Step 7(B) and record on 
Worksheet 5.0-1 the dispersion coefficient for each stack/distance 
range. For stacks located in facilities in flat terrain, the generic 
source numbers were computed in Step 10(C). For stacks located in 
facilities in rolling and complex terrain, the generic source numbers 
were computed in Step 10(D). For flat terrain applications and for 
stacks with a physical height of less than or equal to 10 meters, only 
one generic source number is used per

[[Page 112]]

stack for all distance ranges. For other situations up to three generic 
source numbers may be needed per stack (i.e., a unique generic source 
number per distance range). In Tables 5.0-4 and 5.0-5, the dispersion 
coefficients for distances of 6 km to 20 km are the same for all generic 
source numbers in order to conservatively represent terrain beyond 5 km 
(past the limits of the terrain analysis).

    (F) Estimate maximum hourly ambient air concentrations. In this 
step, pollutant-specific emission rates are multiplied by appropriate 
dispersion coefficients to estimate ambient air concentrations. For each 
stack, emissions are multiplied by the dispersion coefficient selected 
in Step 10(E) and summed across all stacks to estimate ambient air 
concentrations at various distances from the facility. From these summed 
concentrations, the maximum hourly ambient air concentration is 
selected. First, select the maximum emission rate of the pollutant.\11\ 
Record these data in the spaces provided below.\12\
---------------------------------------------------------------------------

    \11\ Recall that it is recommended that this analysis be performed 
for only one or two pollutants. The pollutants chosen for this analysis 
should be those that show the most significant exceedances of the risk 
threshold.
    \12\ Refer to Step 8 of the basic screening procedure. At this point 
in the screening procedure, annual emissions are used to represent 
hourly average emission rates. These values will be adjusted by the 
annual/hourly ratio to estimate annual average concentrations.

    Complete a separate copy of Worksheet 5.0-2 for each pollutant and

    (G) Determine the complex/noncomplex designation for each stack. For 
each stack, subtract the maximum terrain rise within 5 km of the site 
from the physical stack height and designate the stack as either complex 
or noncomplex. If the stack height minus the maximum terrain rise 
(within 5 km) is greater than zero or if the stack is less than 10 
meters in physical height, then assign the stack a noncomplex 
designation. If the stack height minus the maximum terrain rise (within 
5 km) is less than or equal to zero, then assign the stack a complex 
designation.

    Perform the following computation for each stack and record the 
information in the spaces provided. Check in the spaces provided whether 
the stack designation is complex or noncomplex.

    (H) Identify annual/hourly ratios. Extract the annual/hourly ratios 
for each stack by referring to Table 5.0-6. Generic source numbers (from 
Steps 10(C) or 10(D), urban/rural designation (from Step 6)), and 
complex or noncomplex terrain designations (from Step 10(G)) are used to 
select the appropriate scaling factor needed to convert hourly maximum 
concentrations to estimates of annual average concentrations.
    Complete the following table: \13\
---------------------------------------------------------------------------

    \13\ If any stack (excluding generic stack number 1 and 11) in Step

    \14\ As an option, the user can identify the stack with the highest 
ratio for each distance range (rather than the absolute highest). In 
this case, extra sheets would be needed to show estimated annual average 
concentrations from each stack by multiplying emission rate times 
maximum hourly dispersion coefficient times maximum annual/hourly ratio 
for applicable distance range. Then sum across all stacks for each 
downwind distance.

Section 6.0--Simplified Land Use Classification Procedure for Compliance 
                     With Tier I and Tier II Limits

                            6.1 Introduction

    This section provides a simplified procedure to classify areas in 
the vicinity of boilers and industrial furnace sites as urban or rural 
in order to set risk-based emission limits under subpart H of 40 CFR 
part 266. Urban/rural classification is needed because dispersion rates 
differ between urban and rural areas and thus, the risk per unit 
emission rate differs accordingly. The combination of greater surface 
roughness (more buildings/structures to generate turbulent mixing) and 
the greater amount of heat released from the surface in an urban area 
(generates buoyancy-induced mixing) produces greater rates of 
dispersion. The emission limit tables in the regulation, therefore, 
distinguish between urban and rural areas.
    EPA guidance (EPA 1986) \1\ provides two alternative procedures to 
determine whether the character of an area is predominantly urban or 
rural. One procedure is based on land use typing and the other is based 
on population density. Both procedures require consideration of 
characteristics within a 3-km radius from a source, in this case the 
facility stack(s). The land use typing method is preferred because it 
more directly relates to the surface characteristics that affect 
dispersion rates. The remainder of this discussion is, therefore, 
focused on the land use method.
    While the land use method is more direct, it can also be labor-
intensive to apply. For this discussion, the land use method has been 
simplified so that it is consistent with EPA guidance (EPA 1986; Auer 
1978), while streamlining the process for the majority of applications 
so that a clear-cut decision can be made without the need for detailed 
analysis. Table 6.0-1 summarizes the simplified approach for classifying 
areas as urban or rural. As shown, the applicant always has the option 
of applying standard (i.e., more detailed) analyses to more accurately 
distinguish between urban and rural areas. However, the procedure 
presented here allows for simplified determinations, where appropriate, 
to expedite the permitting process.

                    6.2  Simplified Land Use Process

    The land use approach considers four primary land use types: 
industrial (I), commercial (C), residential (R), and agricultural (A). 
Within These primary classes, subclasses are identified, as shown in 
table 6.0-1. The goal is to estimate the percentage of the area within a 
3-km radius that is urban type and the percentage that is rural type. 
Industrial and commercial areas are classified as urban; agricultural 
areas are classified as rural.
    The delineation of urban and rural areas, however, can be more 
difficult for the residential type areas shown in table 6.0-1. The 
degree of resolution shown in table 6.0-1 for residential areas often 
cannot be identified without conducting site area inspections and/or 
referring to zoning maps. This process can require extensive analysis, 
which, for many applications, can be greatly streamlined without 
sacrificing confidence in selecting the appropriate urban or rural 
classification.
    The fundamental simplifying assumption is based on the premise that 
many applications will have clear-cut urban/rural designations, i.e., 
most will be in rural settings that can be definitively characterized 
through a brief review of topographical maps. The color coding on USGS 
topographical maps provides the most effective means of simplifying the 
typing scheme. The suggested typing designations for the color codes 
found on topographical maps are as follows:
Green Wooded areas (rural).
White White areas generally will be treated as rural. This code applies 
to areas that are unwooded and do not have densely packed structures 
which would require the pink code (house omission tint). Parks, 
industrial areas, and unforested rural land will appear as white on the 
topographical maps. Of these categories, only the industrial areas could 
potentially be classified

[[Page 119]]

as urban based on EPA 1986 or Auer 1978. Industrial areas can be easily 
identified in most cases by the characteristics shown in Figure 6.0-1. 
For this simplified procedure, white areas that have an industrial 
classification will be treated as urban areas.

 Section 7.0--Statistical Methodology for Bevill Residue Determinations

    This section describes the statistical comparison of waste-derived 
residue to normal residue for use in determining eligibility for the 
Bevill exemption under 40 CFR 266.112.

        7.1 Comparison of Waste-Derived Residue to Normal Residue

    To be eligible for the Bevill exclusion from the definition of 
hazardous waste under 40 CFR 266.112(b)(1), waste-derived residue must 
not contain Appendix VIII, Part 261, constituents that could reasonably 
be attributable to the hazardous waste (toxic constituents) at 
concentrations significantly higher than in residue generated without 
burning or processing hazardous waste (normal residue). Concentrations 
of toxic constituents in normal residue are determined based on analysis 
of a minimum of 10 samples representing a minimum of 10 days of 
operation. The statistically-derived concentrations in normal residue 
are determined as the upper tolerance limit (95% confidence with a 95% 
proportion of the sample distribution) of the normal residue 
concentrations. The upper tolerance limit is to be determined as 
described in Section 7.2 below. If changes in raw materials or fuels 
could lower the statistically-derived concentrations of toxic 
constituents of concern, the statistically-derived baseline must be re-
established for any such mode of operation with the new raw material or 
fuel.
    Concentrations of toxic constituents in waste-derived residue are 
determined based on the analysis of one or more samples collected over a 
compositing period of not more than 24 hours. Mulitple samples of the 
waste-derived residue may be analyzed or subsamples may be composited 
for analysis, provided that the sampling period does not exceed 24 
hours. If more than one sample is analyzed to characterize the waste-
derived residue generated over a 24-hour period, the arithmetic mean of 
the concentrations must be used as the waste-derived concentration for 
each constituent.
    The concentration of a toxic constituent in the waste-derived 
residue is not considered to be significantly higher than in the normal 
residue (i.e., the residue passes the Bevill test for that constituent) 
if the concentration in the waste-derived residue does not exceed the 
statistically-derived concentration.

              7.2 Calculation of the Upper Tolerance Limit

    The 95% confidence with 95% proportion of the sample distribution 
(upper tolerance limit) is calculated for a set of values assuming that 
the values are normally distributed. The upper tolerance limit is a one-
sided calculation and is an appropriate statistical test for cases in 
which a single value (the waste-derived residue concentration) is 
compared to the distribution of a range of values (the minimum of 10 
measurements of normal residue concentrations). The upper tolerance 
limit value is determined as follows:

    UTL = X + (K)(S)
where X = mean of the normal residue concentrations, X = X i/
          n,
K = coefficient for sample size n, 95% confidence and 95% proportion,
S = standard deviation of the normal residue concentrations,
S = ([Sigma](Xi - X)\2\/(n - 1))\0\.\5\, and
n = sample size.
    The values of K at the 95% confidence and 95% proportion, and sample 
size n are given in Table 7.0-1.
    For example, a normal residue test results in 10 samples with the 
following analytical results for toxic constituent A:

    The mean and the standard deviation of these measurements, 
calculated using the above equations, are 11.5 and 2.9, respectively. 
Assuming that the values are normally distributed, the upper tolerance 
limit (UTL) is given by:

UTL=11.5+(2.911)(2.9)=19.9 ppm

    This, if the concentration of constituent A in the waste-derived 
residue is below 19.9 ppm, then the waste-derived residue is eligible 
for the Bevill exclusion for constituent A.

                   7.3 Normal Distribution Assumption

    As noted in Section 7.2 above, this statistical approach (use of the 
upper tolerance limit) for calculation of the concentration in normal 
residue is based on the assumption that the concentration data are 
distributed normally. The Agency is aware that concentration data of 
this type may not always be distributed normally, particularly when 
concentrations are near the detection limits. There are a number of 
procedures that can be used to test the distribution of a data set. For 
example, the Shapiro-Wilk test, examination of a histogram or plot of 
the data on normal probability paper, and examination of the coefficient 
of skewness are methods that may be applicable, depending on the nature 
of the data (References 1 and 2).

[[Page 121]]

    If the concentration data are not adequately represented by a normal 
distribution, the data may be transformed to attain a near normal 
distribution. The Agency has found that concentration data, especially 
when near detection levels, often exhibit a lognormal distribution. The 
assumption of a lognormal distribution has been used in various programs 
at EPA, such as in the Office of Solid Waste Land Disposal Restrictions 
program for determination of BDAT treatment standards. The transformed 
data may be tested for normality using the procedures identified above. 
If the transformed data are better represented by a normal distribution 
than the untransformed data, the transformed data should be used in 
determining the upper tolerance limit using the procedures in Section 
7.2 above.
    In all cases where the owner or operator wishes to use other than an 
assumption of normally distributed data or believes that use of an 
alternate statistical approach is appropriate to the specific data set, 
he/she must provide supporting rationale in the operating record that 
demonstrates that the data treatment is based upon sound statistical 
practice.

                          7.4 Nondetect Values

    The Agency is developing guidance regarding the treatment of 
nondetect values (data where the concentration of the constituent being 
measured is below the lowest concentration for which the analytical 
method is valid) in carrying out the statistical determination described 
above. Until the guidance information is available, facilities may 
present their own approach to the handling of nondetect data points, but 
must provide supporting rationale in the operating record for 
consideration by the Director.

Section 8.0--Procedures for Determining Default Values for Air Pollution 
                   Control System Removal Efficiencies

    During interim status, owners or operators of boilers and industrial 
furnaces burning hazardous waste must submit documentation to EPA that 
certifies that emissions of HCl, C12, metals, and particulate 
matter (PM) are not likely to exceed allowable emission rates. See 
certification of precompliance under 40 CFR 266.103(b). This 
documentation also establishes interim status feed rate and operating 
limits for the facility. For the initial certification, estimates of 
emissions and system removal efficiencies (SREs) can be made to 
establish the operating limits. Subsequently, owners or operators must 
use emissions testing to demonstrate that emissions do not exceed 
allowable levels, and to establish operating limits. See 40 CFR 
266.103(c). However, initial estimates of emissions for certification of 
precompliance can be based on estimated or established SREs.
    The SRE combines the effect of partitioning of the chorine, metals, 
or PM and the air pollution control system removal efficiency (APCS RE) 
for these pollutants. The SRE is defined as:
SRE=(species input--species emitted) / species input
    The SRE can be calculated from the partitioning factor (PF) and APCS 
RE by the following formula:
SRE=1--[(PF/l00) X (1--APCS RE/100)]

where:

PF=percentage of the pollutant partitioned to the combustion gas
    Estimates of the PF and/or the APCS RE can be based on either EPA's 
default values or engineering judgement. EPA's `default values for the 
APCS RE for metals, HCl, Cl2, and PM are described in this 
section. EPA's default values for partitioning of these pollutants are 
described in section 9.0.
    Guidelines for the use of engineering judgement to estimate APCS REs 
or PFs are described in section 9.4.

                  8.1 APCS RE Default Values for Metals

    EPA's default assumptions for APCS RE for metals are shown in Table 
8.1-1. The default values in the table are conservative estimates of the 
removal efficiencies for metals in BIFs, depending on the volatility of 
the metal and the type of APCS.
    The volatility of a metal depends on the temperature, the thermal 
input, the chlorine

[[Page 122]]

content of the waste, and the identity and concentration of the metal. 
Metals that do not vaporize at combustion zone temperatures are 
classified as ``nonvolatile''. Such metals typically enter the APCS in 
the form of large particles that are removed relatively easily. Metals 
that vaporize in the combustion zone and condense before entering the 
APCS are classified as ``volatile''. Such metals typically enter the 
APCS in the form of very fine, submicron particles that are rather 
inefficiently removed in many APCSs. Metals that vaporize in the 
combustion zone and do not condense before entering the APCS are 
classified as ``very volatile''. Such metals enter the APCS in the form 
of a vapor that is very inefficiently removed in many APCSs.
    Typically, BIFs have combustion zone temperatures high enough to 
vaporize any hazardous metal at concentrations sufficient to exceed 
risk-based emission limits. For this reason, the default assumption is 
that there are no nonvolatile metals. Tables 8.1-2 and 8.1-3 are used to 
determine whether metals are classified as ``volatile'' or ``very 
volatile'' depending on the temperature entering the APCS, the thermal 
input, and whether the waste is chlorinated or nonchlorinated.

    Default assumptions for APCS RE for HCl in BIFs are shown in Table 
8.2-1. This table is identical to the column for other BIFs except that 
cement kilns have a minimum HCl removal efficiency of 83 percent. 
Because of the alkaline nature of the raw materials in cement kilns, 
most of the chlorine is converted to chloride salts. Thus, the minimum 
APCS RE for HCl for cement kilns is independent of the APCS train.
    Removal efficiency of Cl2 for most types of APCS is 
generally minimal. Therefore, the default assumption for APCS RE for 
Cl2 for all APCSs is 0 percent. This is applicable to all 
BIFs, including cement kilns.

                   8.3 APCS RE Default Values for Ash

    Default assumptions for APCS RE for PM are also shown in Table 8.1-
4. These figures are conservative estimates of PM removal efficiencies 
for different types of APCSs. They are identical to the figures in the 
Nonvolatile APCS RE column for hazardous metals presented in Table 8.1-1 
because the same collection mechanisms and collection efficiencies that 
apply to nonvolatile metals also apply to PM.

Section 9.0--Procedures for Determining Default Values for Partitioning 
               of Metals, Ash, and Total Chloride/Chlorine

    Pollutant partitioning factor estimates can come from two sources: 
default assumptions or engineering judgement. EPA's default assumptions 
are discussed below for metals, HCl, Cl2, and PM. The default 
assumptions are used to conservatively predict the partitioning factor 
for several types of BIFs. Engineering judgement-based partitioning 
factor estimates are discussed in section 9.4.

                9.1 Partitioning Default Value for Metals

    To be conservative, the Agency is assuming that 100 percent of each 
metal in each feed stream is partitioned to the combustion gas. Owners/
operators may use this default value or a supportable, site-specific 
value developed following the general guidelines provided in section 
9.4.

      9.2 Special Procedures for Chlorine, HCl, and Cl2

    The Agency has established the special procedures presented below 
for chlorine because the emission limits are based on the pollutants HCl 
and Cl2 formed from chlorine fed to the combustor. Therefore, the owner/
operator must estimate the controlled emission rate of both HCl and 
Cl2 and show that they do not exceed allowable levels.
    1. The default partitioning value for the fraction of chlorine in 
the total feed streams that is partitioned to combustion gas is 100 
percent. Owners/operators may use this default value or a supportable, 
site-specific value developed following the general guidelines provided 
in section 9.4.
    2. To determine the partitioning of chlorine in the combustion gas 
to HCl versus Cl2, either use the default values below or use 
supportable site-specific values developed following the general 
guidelines provided in section 9.4.
    [sbull] For BIFs excluding halogen acid furnaces (HAFs), with a 
total feed stream chlorine/hydrogen ratio [le]0.95, the default 
partitioning factor is 20 percent Cl2, 80 percent HCl.
    [sbull] For HAFs and for BIFs with a total feed stream chlorine/
hydrogen ratio 0.95, the default partitioning factor is 100 
percent Cl2.
    3. To determine the uncontrolled (i.e., prior to acid gas APCS) 
emission rate of HCl and Cl2, multiply the feed rate of 
chlorine times the partitioning factor for each pollutant. Then, for 
HCl, convert the chlorine emission rate to HCl by multiplying it by the 
ratio of the molecular weight of HCl to the molecular weight of Cl 
(i.e., 36.5/35.5). No conversion is needed for Cl2.

                     9.3 Special Procedures for Ash

    This section: (1) Explains why ash feed rate limits are not 
applicable to cement and light-weight aggregate kilns; (2) presents the 
default partitioning values for ash; and (3) explains how to convert the 
0.08 gr/dscf, corrected to 7% O2, PM emission limit to a PM 
emission rate.
    Waiver for Cement and Light-Weight Aggregate Kilns. For cement kilns 
and light-weight aggregate kilns, raw material feed streams contain the 
vast majority of the ash input, and a significant amount of the ash in 
the feed stream is entrained into the kiln exhaust gas. For these 
devices, the ash content of the hazardous waste stream is expected to 
have a negligible effect on total ash emissions. For this reason, there 
is no ash feed rate compliance limit for cement kilns or light-weight 
aggregate kilns. Nonetheless, cement kilns and light-weight aggregate 
kilns are required to initially certify that PM emissions are not likely 
to exceed the PM limit, and subsequently, certify through compliance 
testing that the PM limit is not exceeded.
    Default Partitioning Value for Ash. The default assumption for 
partitioning of ash depends on the feed stream firing system. There are 
two methods by which materials may be fired into BIFs: Suspension-firing 
and bed-firing.
    The suspension category includes atomized and lanced pumpable 
liquids and suspension-fired pulverized solids. The default partitioning 
assumption for materials fired by these systems is that 100 percent of 
the ash partitions to the combustion gas.
    The bed-fired category consists principally of stoker boilers and 
raw materials (and in some cases containerized hazardous waste) fed into 
cement and light-weight aggregate kilns. The default partitioning 
assumption for materials fired on a bed is that 5 percent of the ash 
partitions to the combustion gas.
    Converting the PM Concentration-Based Standard to a PM Mass Emission 
Rate. The emission limit for BIFs is 0.08 gr/dscf, corrected to 7% 
02, unless a more stringent standard applies [e.g., a New 
Source Performance Standard (NSPS) or a State standard implemented under 
the State Implementation Plan (SIP)]. To convert the 0.08 gr/dscf 
standard to a PM mass emission rate:
    1. Determine the flue gas 02 concentration (percent by 
volume, dry) and flue gas flow rate (dry standard cubic feet per 
minute); and
    2. Calculate the allowable PM mass emission rate by multiplying the 
concentration- based PM emission standard times the flue

[[Page 125]]

gas flow rate times a dilution correction factor equal to [(21-
02 concentration from step 1)/(21-7)].

 9.4 Use of Engineering Judgement To Estimate Partitioning and APCS RE 
                                 Values

    Engineering judgement may be used in place of EPA's conservative 
default assumptions to estimate partitioning and APCS RE values provided 
that the engineering judgement is defensible and properly documented. To 
properly document engineering judgement, the owner/operator must keep a 
written record of all assumptions and calculations necessary to justify 
the APCS RE used. The owner/operator must provide this record to the 
Director upon request and must be prepared to defend the assumptions and 
calculations used.
    If the engineering judgement is based on emissions testing, the 
testing will often document the emission rate of a pollutant relative to 
the feed rate of that pollutant rather than the partitioning factor or 
APCS RE.
    Examples of situations where the use of engineering judgement may be 
supportable to estimate a partitioning factor, APCS RE, or SRE include:
    [sbull] Using emissions testing data from the facility to support an 
SRE, even though the testing may not meet full QA/QC procedures (e.g., 
triplicate test runs). The closer the test results conform with full QA/
QC procedures and the closer the operating conditions during the test 
conform with the established operating conditions for the facility, the 
more supportable the engineering judgement will be.
    [sbull] Applying emissions testing data documenting an SRE for one 
metal, including nonhazardous surrogate metals to another less volatile 
metal.
    [sbull] Applying emissions testing data documenting an SRE from one 
facility to a similar facility.
    [sbull] Using APCS vendor guarantees of removal efficiency.

                  9.5 Restrictions on Use of Test Data

    The measurement of an SRE or an APCS RE may be limited by the 
detection limits of the measurement technique. If the emission of a 
pollutant is undetectable, then the calculation of SRE or APCS RE should 
be based on the lower limit of detectability. An SRE or APCS RE of 100 
percent is not acceptable.
    Further, mass balance data of facility inputs, emissions, and 
products/residues may not be used to support a partitioning factor, 
given the inherent uncertainties of such procedures. Partitioning 
factors other than the default values may be supported based on 
engineering judgement, considering, for example, process chemistry. 
Emissions test data may be used to support an engineering judgement-
based SRE, which includes both partitioning and APCS RE.

 Section 10.0--Alternative Methodology for Implementing Metals Controls

                           10.1 Applicability

    This method for controlling metals emissions applies to cement kilns 
and other industrial furnaces operating under interim status that 
recycle emission control residue back into the furnace.

                            10.2 Introduction

    Under this method, cement kilns and other industrial furnaces that 
recycle emission control residue back into the furnace must comply with 
a kiln dust concentration limit (i.e., a collected particulate matter 
(PM) limit) for each metal, as well as limits on the maximum feedrates 
of each of the metals in: (1) pumpable hazardous waste; and (2) all 
hazardous waste.
    The following subsections describe how this method for controlling 
metals emissions is to be implemented:
    [sbull] Subsection 10.3 discusses the basis of the method and the 
assumptions upon which it is founded;
    [sbull] Subsection 10.4 provides an overview of the implementation 
of the method;
    [sbull] Subsection 10.5 is a step-by-step procedure for 
implementation of the method;
    [sbull] Subsection 10.6 describes the compliance procedures for this 
method; and
    [sbull] Appendix A describes the statistical calculations and tests 
to be used in the method.

                               10.3 Basis

    The viability of this method depends on three fundamental 
assumptions:
    (1) Variations in the ratio of the metal concentration in the 
emitted particulate to the metal concentration in the collected kiln 
dust (referred to as the enrichment factor or EF) for any given metal at 
any given facility will fall within a normal distribution that can be 
experimentally determined.
    (2) The metal concentrations in the collected kiln dust can be 
accurately and representatively measured (using procedures specified in 
``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods'' 
(SW-846), incorporated by reference in 40 CFR 260.11).
    (3) The facility will remain in compliance with the applicable 
particulate matter (PM) emission standard.

[[Page 126]]

    Given these assumptions. metal emissions can be related to the 
measured concentrations in the collected kiln dust by the following 
equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.014

Where:

ME is the metal emitted;
PME is the particulate matter emitted;
DMC is the metal concentration in the collected kiln dust; and
EF is the enrichment factor, which is the ratio of the metal 
          concentration in the emitted particulate matter to the metal 
          concentration in the collected kiln dust.
    This equation can be rearranged to calculate a maximum allowable 
dust metal concentration limit (DMCL) by assuming worst-case conditions 
that: metal emissions are at the Tier III (or Tier II) limit (see 40 CFR 
266.106), and that particulate emissions are at the particulate matter 
limit (PML):
[GRAPHIC] [TIFF OMITTED] TC06NO91.015

    The enrichment factor used in the above equation must be determined 
experimentally from a minimum of 10 tests in which metal concentrations 
are measured in kiln dust and stack samples taken simultaneously. This 
approach provides a range of enrichment factors that can be inserted 
into a statistical distribution (t-distribution) to determine 
EF95[sbull] and EF99[sbull]. 
EF95[sbull] is the value at which there is a 95% confidence 
level that the enrichment factor is below this value at any given time. 
Similarly, EF99[sbull] is the value at which there is a 99% 
confidence level that the enrichment factor is below this value at any 
given time. EF95[sbull] is used to calculate the 
``violation'' dust metal concentration limit (DMCLv):
[GRAPHIC] [TIFF OMITTED] TC06NO91.016

    If the kiln dust metal concentration is just above this 
``violation'' limit, and the PM emissions are at the PM emissions limit, 
there is a 5% chance that the metal emissions are above the Tier III 
limit. In such a case, the facility would be in violation of the metals 
standard.

[[Page 127]]

    To provide a margin of safety, a second, more conservative kiln dust 
metal concentration limit is also used. This ``conservative'' dust metal 
concentration limit (DMCLc) is calculated using a ``safe'' 
enrichment factor (SEF). If EF99[sbull] is greater than two 
times the value of EF95[sbull], the ``safe'' enrichment 
factor can be calculated using Equation 4a:
SEF[ge]2 EF95[sbull] (4a)Q02
    If EF99[sbull] is not greater than two times the value of 
EF95[sbull], the ``safe'' enrichment factor can be calculated 
using Equation 4b:
SEF[ge] EF99[sbull] (4b)
    In cases where the enrichment factor cannot be determined because 
the kiln dust metal concentration is nondetectable, the ``safe'' 
enrichment factor is as follows:
SEF=100 (4c)
    For all cases, the ``conservative'' dust metal concentration limit 
is calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TC06NO91.017

    If the kiln dust metal concentration at a facility is just above the 
``conservative'' limit based on that ``safe'' enrichment factor provided 
in Equation 4a, and the PM emissions are at the PM emissions limit, 
there is a 5% chance that the metal emissions are above one-half the 
Tier III limit. If the kiln dust metal concentration at the facility is 
just above the ``conservative'' limit based on the ``safe'' enrichment 
factor provided in Equation 4b, and the PM emissions are at the PM 
emissions limit, there is a 1% chance that the metal emissions are above 
the Tier III limit. In either case, the facility would be unacceptably 
close to a violation. If this situation occurs more than 5% of the time, 
the facility would be required to rerun the series of 10 tests to 
determine the enrichment factor. To avoid this expense. the facility 
would be advised to reduce its metals feedrates or to take other 
appropriate measures to maintain its kiln dust metal concentrations in 
compliance with the ``conservative'' dust metal concentration limits.
    In cases where the enrichment factor cannot be determined because 
the kiln dust metal concentration is nondetectable, and thus no 
EF95[Lt] exists, the ``violation'' dust metal concentration 
limit is set at ten times the ``conservative'' limit:
DMCLv=10xDMCLc (6)

                              10.4 Overview

    The flowchart for implementing the method is shown in Figure 10.4-1. 
The general procedure is as follows:
    [sbull] Follow the certification of precompliance procedures 
described in subsection 10.6 (to comply with 40 CFR 266.103(b)).
    [sbull] For each metal of concern, perform a series of tests to 
establish the relationship (enrichment factor) between the concentration 
of emitted metal and the metal concentration in the collected kiln dust.
    [sbull] Use the demonstrated enrichment factor, in combination with 
the Tier III (or Tier II) metal emission limit and the most stringent 
applicable particulate emission limit, to calculate the ``violation'' 
and ``conservative'' dust metal concentration limits. Include this 
information with the certification of compliance under 40 CFR 
266.103(c).

[[Page 128]]

[GRAPHIC] [TIFF OMITTED] TC01AU92.042

    [sbull] Perform daily and/or weekly monitoring of the cement kiln 
dust metal concentration to ensure (with appropriate QA/QC) that the 
metal concentration does not exceed either limit.
--If the cement kiln dust metal concentration exceeds the 
``conservative'' limit more than 5% of the time (i.e., more than three 
failures in last 60 tests), the series of tests to determine the 
enrichment factor must be repeated.
--If the cement kiln dust metal concentration exceeds the ``violation'' 
limit, a violation has occurred.

    [sbull] Perform quarterly tests to verify that the enrichment factor 
has not increased significantly. If the enrichment factor has increased, 
the series of tests to determine the enrichment factor must be repeated.

[[Page 129]]

                     10.5 Implementation Procedures

    A step-by-step description for implementing the method is provided 
below:
    (1) Prepare initial limits and test plans.
    [sbull] Determine the Tier III metal emission limit. The Tier II 
metal emission limit may also be used (see 40 CFR 266.106).
    [sbull] Determine the applicable PM emission standard. This standard 
is the most stringent particulate emission standard that applies to the 
facility. A facility may elect to restrict itself to an even more 
stringent self-imposed PM emission standard, particularly if the 
facility finds that it is easier to control particulate emissions than 
to reduce the kiln dust concentration of a certain metal (i.e., lead).
    [sbull] Determine which metals need to be monitored (i.e., all 
hazardous metals for which Tier III emission limits are lower than PM 
emission limits--assuming PM is pure metal).
    [sbull] Follow the compliance procedures described in Subsection 
10.6.
    [sbull] Follow the guidelines described in SW-846 for preparing test 
plans and waste analysis plans for the following tests:
--Compliance tests to determine limits on metal feedrates in pumpable 
hazardous wastes and in all hazardous wastes (as well as to determine 
other compliance parameters);
--Initial tests to determine enrichment factors;
--Quarterly tests to verify enrichment factors;
--Analysis of hazardous waste feedstreams; and
--Daily and/or weekly monitoring of kiln dust for continuing compliance.

    (2) Conduct tests to determine the enrichment factor.
    [sbull] These tests must be conducted within a 14-day period. No 
more than two tests may be conducted in any single day. If the tests are 
not completed within a 14-day period, they must be repeated.
    [sbull] Simultaneous stack samples and kiln dust samples must be 
taken.
--Stack sampling must be conducted with the multiple metals train 
according to procedures provided in section 10.3 of this Methods Manual.
--Kiln dust sampling must be conducted as follows:
--Follow the sampling and analytical procedures described in SW-846 and 
the waste analysis plan as they pertain to the condition and 
accessibility of the dust.
--Samples should be representative of the last ESP or Fabric Filter in 
the APCS series.

    [sbull] The feedrates of hazardous metals in all pumpable hazardous 
waste streams and in all hazardous waste streams must be monitored 
during these tests. It is recommended (but not required) that the 
feedrates of hazardous metals in all feedstreams also be monitored.
    [sbull] At least ten single (noncomposited) runs are required during 
the tests.
--The facility must follow a normal schedule of kiln dust recharging for 
all of the tests.
--Three of the first five tests must be compliance tests in conformance 
with 40 CFR 266.103(c); i.e., they must be used to determine maximum 
allowable feedrates of metals in pumpable hazardous wastes. and in all 
hazardous wastes, as well as to determine other compliance limits (see 
40 CFR 266.103(c)(1)).
--The remainder of the tests need not be conducted under full compliance 
test conditions; however, the facility must operate at its compliance 
test production rate, and it must burn hazardous waste during these 
tests such that the feedrate of each metal for pumpable and total 
hazardous wastes is at least 25% of the feedrate during compliance 
testing. If these criteria, and those discussed below, are not met for 
any parameter during a test, then either the test is not valid for 
determining enrichment factors under this method, or the compliance 
limits for that parameter must be established based on these test 
conditions rather than on the compliance test conditions.

    [sbull] Verify that compliance emission limits are not exceeded.
--Metal emissions must not exceed Tier III (or Tier II) limits.
--PM emissions must not exceed the most stringent of applicable PM 
standards (or an optional self-imposed particulate standard).
    [sbull] The facility must generate normal, marketable product using 
normal raw materials and fuels under normal operating conditions (for 
parameters other than those specified under this method) when these 
tests are conducted.
    [sbull] Chromium must be treated as a special case:
--The enrichment factor for total chromium is calculated in the same way 
as the enrichment factor for other metals (i.e., the enrichment factor 
is the ratio of the concentration of total chromium in the emitted 
particulate matter to the concentration of total chromium in the 
collected kiln dust).
--The enrichment factor for hexavalent chromium (if measured) is defined 
as the ratio of the concentration of hexavalent chromium in the emitted 
particulate matter to the concentration of total chromium in the 
collected kiln dust.

    (3) Use the enrichment factors measured in Step 2 to determine 
EF95[Lt], EF99[Lt], and SEF.
    [sbull] Calculate EF95[Lt] and EF99[Lt] 
according to the t-distribution as described in Appendix A
    [sbull] Calculate SEF by

[[Page 130]]

--Equation 4a if EF95[Lt] is determinable and if 
EF99[Lt] is greater than two times EF95[Lt],
--Equation 4b if EF95[Lt] is determinable and if 
EF99[Lt] is not greater than two times EF95[Lt].
--Equation 4c if EF95[Lt] is not determinable.

    The facility may choose to set an even more conservative SEF to give 
itself a larger margin of safety between the point where corrective 
action is necessary and the point where a violation occurs.
    (4) Prepare certification of compliance.
    [sbull] Calculate the ``conservative'' dust metal concentration 
limit (DMCLc) using Equation 5.
--Chromium is treated as a special case. The ``conservative'' kiln dust 
chromium concentration limit is set for total chromium, not for 
hexavalent chromium. The limit for total chromium must be calculated 
using the Tier III (or Tier II) metal limit for hexavalent chromium.
--If the stack samples described in Step 2 were analyzed for hexavalent 
chromium, the SEF based on the hexavalent chromium enrichment factors 
(as defined in Step 2) must be used in this calculation.
--If the stack samples were not analyzed for hexavalent chromium, then 
the SEF based on the total chromium enrichment factor must be used in 
this calculation.

    [sbull] Calculate the ``violation'' dust metal concentration limit 
(DMCLv) using Equation 3 if EF95[Lt] is 
determinable, or using Equation 6 if EF95[Lt] is not 
determinable.
--Chromium is treated as a special case. The ``violation'' kiln dust 
chromium concentration limit is set for total chromium, not for 
hexavalent chromium. The limit for total chromium must be calculated 
using the Tier III (or Tier II) metal limit for hexavalent chromium.
--If the stack samples taken in Step 2 were analyzed for hexavalent 
chromium, the EF95[Lt] based on the hexavalent chromium 
enrichment factor (as defined in Step 2) should be used in this 
calculation.
--If the stack samples were not analyzed for hexavalent chromium, the 
EF95[Lt] based on the total chromium enrichment factor must 
be used in this calculation.

    [sbull] Submit certification of compliance.
    [sbull] Steps 2-4 must be repeated for recertification, which is 
required once every 3 years (see Sec. 266.103(d)).
    (5) Monitor metal concentrations in kiln dust for continuing 
compliance, and maintain compliance with all compliance limits for the 
duration of interim status.
    [sbull] Metals to be monitored during compliance testing are 
classified as either ``critical'' or ``noncritical'' metals.
--All metals must initially be classified as ``critical'' metals and be 
monitored on a daily basis.
--A ``critical'' metal may be reclassified as a ``noncritical'' metal if 
its concentration in the kiln dust remains below 10% of its 
``conservative'' kiln dust metal concentration limit for 30 consecutive 
daily samples. ``Noncritical'' metals must be monitored on a weekly 
basis.
--A ``noncritical'' metal must be reclassified as a ``critical'' metal 
if its concentration in the kiln dust is above 10% of its 
``conservative'' kiln dust metal concentration limit for any single 
daily or weekly sample.

    [sbull] Noncompliance with the sampling and analysis schedule 
prescribed by this method is a violation of the metals controls under 
Sec. 266.103.
    [sbull] Follow the sampling, compositing, and analytical procedures 
described in this method and in SW-846 as they pertain to the condition 
and accessibility of the kiln dust.
    [sbull] Follow the same procedures and sample at the same locations 
as were used for kiln dust samples collected to determine the enrichment 
factors (as discussed in Step 2).
    [sbull] Samples must be collected at least once every 8 hours, and a 
daily composite must be prepared according to SW-846 procedures.
--At least one composite sample is required. This sample is referred to 
as the ``required'' sample.
--For QA/QC purposes, a facility may elect to collect two or more 
additional samples. These samples are referred to as the ``spare'' 
samples. These additional samples must be collected over the same time 
period and according to the same procedures as those used for the 
``required'' sample.
--Samples for ``critical'' metals must be daily composites.
--Samples for ``noncritical'' metals must be weekly composites. These 
samples can be composites of the original 8-hour samples, or they can be 
composites of daily composite samples.
    [sbull] Analyze the ``required'' sample to determine the 
concentration of each metal.
--This analysis must be completed within 48 hours of the close of the 
sampling period. Failure to meet this schedule is a violation of the 
metals standards of Sec. 266.103.

    [sbull] If the ``conservative'' kiln dust metal concentration limit 
is exceeded for any metal, refer to Step 8.
    [sbull] If the ``conservative'' kiln dust metal concentration limit 
is not exceeded, continue with the daily or weekly monitoring (Step 5) 
for the duration of interim status.
    [sbull] Conduct quarterly enrichment factor verification tests, as 
described in Step 6.
    (6) Conduct quarterly enrichment factor verification tests.
    [sbull] After certification of compliance with the metals standards, 
a facility must conduct quarterly enrichment factor verification tests 
every three months for the duration of interim status. The first 
quarterly test must be completed within three

[[Page 131]]

months of certification (or recertification). Each subsequent quarterly 
test must be completed within three months of the preceding quarterly 
test. Failure to meet this schedule is a violation.
    [sbull] Simultaneous stack samples and kiln dust samples must be 
collected.
    [sbull] Follow the same procedures and sample at the same locations 
as were used for kiln dust samples and stack samples collected to 
determine the enrichment factors (as discussed in Step 2).
    [sbull] At least three single (noncomposited) runs are required. 
These tests need not be conducted under the operating conditions of the 
initial compliance test; however, the facility must operate under the 
following conditions:
--It must operate at compliance test production rate.
--It must burn hazardous waste during the test, and for the 2-day period 
immediately preceding the test, such that the feedrate of each metal for 
pumpable and total hazardous wastes consist of at least 25% of the 
operating limits established during the compliance test.
--It must remain in compliance with all compliance parameters (see 
Sec. 266.103(c)(1)).
--It must follow a normal schedule of kiln dust recharging.
--It must generate normal marketable product from normal raw materials 
during the tests.

    (7) Conduct a statistical test to determine if the enrichment 
factors measured in the quarterly verification tests have increased 
significantly from the enrichment factors determined in the tests 
conducted in Step 2. The enrichment factors have increased significantly 
if all three of the following criteria are met:
    [sbull] By applying the t-test described in appendix A, it is 
determined that the enrichment factors measured in the quarterly tests 
are not taken from the same population as the enrichment factors 
measured in the Step 2 tests;
    [sbull] The EF95[ap] calculated for the combined data 
sets (i.e., the quarterly test data and the original Step 2 test data) 
according to the t-distribution (described in appendix A) is more than 
10% higher than the EF95[ap] based on the enrichment factors 
previously measured in Step 2; and
    [sbull] The highest measured kiln dust metal concentration recorded 
in the previous quarter is more than 10% of the ``violation'' kiln dust 
concentration limit that would be calculated from the combined 
EF95[percnt].
    If the enrichment factors have increased significantly, the tests to 
determine the enrichment factors must be repeated (refer to Step 11). If 
the enrichment factors have not increased significantly, continue to use 
the kiln dust metal concentration limits based on the enrichment factors 
previously measured in Step 2, and continue with the daily and/or weekly 
monitoring described in Step 5.
    (8) If the ``conservative'' kiln dust metal concentration limit was 
exceeded for any metal in any single analysis of the ``required'' kiln 
dust sample, the ``spare'' samples corresponding to the same period may 
be analyzed to determine if the exceedance was due to a sampling or 
analysis error.
    [sbull] If no ``spare'' samples were taken, refer to Step 9.
    [sbull] If the average of all the samples for a given day (or week, 
as applicable) (including the ``required'' sample and the ``spare'' 
samples) does not exceed the ``conservative'' kiln dust metal 
concentration limit, no corrective measures are necessary; continue with 
the daily and/or weekly monitoring as described in Step 5.
    [sbull] If the average of all the samples for a given day (or week, 
as applicable) exceeds the ``conservative'' kiln dust metal 
concentration limit, but the average of the ``spare'' samples is below 
the ``conservative'' kiln dust metal concentration limit, apply the Q-
test, described in appendix A, to determine whether the ``required'' 
sample concentration can be judged as an outlier.
--If the ``required'' sample concentration is judged an outlier, no 
corrective measures are necessary; continue with the daily and/or weekly 
monitoring described in Step 5.
--If the ``required'' sample concentration is not judged an outlier, 
refer to Step 9.

    (9) Determine if the ``violation'' kiln dust metal concentration has 
been exceeded based on either the average of all the samples collected 
during the 24-hour period in question, or if discarding an outlier can 
be statistically justified by the Q-test described in appendix A, on the 
average of the remaining samples.
    [sbull] If the ``violation'' kiln dust metal concentration limit has 
been exceeded, a violation of the metals controls under Sec. 266.103(c) 
has occurred. Notify the Director that a violation has occurred. 
Hazardous waste may be burned for testing purposes for up to 720 
operating hours to support a revised certification of compliance. Note 
that the Director may grant an extension of the hours of hazardous waste 
burning under Sec. 266.103(c)(7) if additional burning time is needed to 
support a revised certification for reasons beyond the control of the 
owner or operator. Until a revised certification of compliance is 
submitted to the Director, the feedrate of the metals in violation in 
total and pumpable hazardous waste feeds is limited to 50% of the 
previous compliance test limits.
    [sbull] If the ``violation'' kiln dust metal concentration has not 
been exceeded:
--If the exceedance occurred in a daily composite sample, refer to Step 
10.
--If the exceedance occurred in a weekly composite sample, refer to Step 
11.


[[Page 132]]


    (10) Determine if the ``conservative'' kiln dust metal concentration 
limit has been exceeded more than three times in the last 60 days.
    [sbull] If not, log this exceedance and continue with the daily and/
or weekly monitoring (Step 5).
    [sbull] If so, the tests to determine the enrichment factors must be 
repeated (refer to Step 11).
    [sbull] This determination is made separately for each metal. For 
example,
--Three exceedances for each of the ten hazardous metals are allowed 
within any 60-day period.
--Four exceedances of any single metal in any 60-day period is not 
allowed.

    [sbull] This determination should be made daily, beginning on the 
first day of daily monitoring. For example, if four exceedances of any 
single metal occur in the first four days of daily monitoring, do not 
wait until the end of the 60-day period; refer immediately to Step 11.
    (11) The tests to determine the enrichment factor must be repeated 
if: (1) More than three exceedances of the ``conservative'' kiln dust 
metal concentration limit occur within any 60 consecutive daily samples; 
(2) an excursion of the ``conservative'' kiln dust metal concentration 
limit occurs in any weekly sample; or (3) a quarterly test indicates 
that the enrichment factors have increased significantly.
    [sbull] The facility must notify the Director if these tests must be 
repeated.
    [sbull] The facility has up to 720 hazardous-waste-burning hours to 
redetermine the enrichment factors for the metal or metals in question 
and to recertify (beginning with a return to Step 2). During this 
period, the facility must reduce the feed rate of the metal in violation 
by 50%. If the facility has not completed the recertification process 
within this period, it must stop burning or obtain an extension. 
Hazardous waste burning may resume only when the recertification process 
(ending with Step 4) has been completed.
    [sbull] Meanwhile, the facility must continue with daily kiln dust 
metals monitoring (Step 5) and must remain in compliance with the 
``violation'' kiln dust metal concentration limits (Step 9).

                      10.6 Precompliance Procedures

    Cement kilns and other industrial furnaces that recycle emission 
control residue back into the furnace must comply with the same 
certification schedules and procedures (with the few exceptions 
described below) that apply to other boilers and industrial furnaces. 
These schedules and procedures, as set forth in Sec. 266.103, require no 
later than the effective date of the rule, each facility submit a 
certification which establishes precompliance limits for a number of 
compliance parameters (see Sec. 266.103(b)(3)), and that each facility 
immediately begin to operate under these limits.
    These precompliance limits must ensure that interim status emissions 
limits for hazardous metals, particulate matter, HCl, and Cl2 
are not likely to be exceeded. Determination of the values of the 
precompliance limits must be made based on either (1) conservative 
default assumptions provided in this Methods Manual, or (2) engineering 
judgement.
    The flowchart for implementing the precompliance procedures is shown 
in Figure 10.6-1. The step-by-step precompliance implementation 
procedure is described below. The precompliance implementation 
procedures and numbering scheme are similar to those used for the 
compliance procedures described in Subsection 10.5.
    (1) Prepare initial limits and test plans.
    [sbull] Determine the Tier III metal emission limit. The Tier II 
metal emission limit may also be used (see 40 CFR 266.106).
    [sbull] Determine the applicable PM emission standard. This standard 
is the most stringent particulate emission standard that applies to the 
facility. A facility may elect to restrict itself to an even more 
stringent self-imposed PM emission standard, particularly if the 
facility finds that it is easier to control particulate emissions than 
to reduce the kiln dust concentration of a certain metal (i.e., lead).
    [sbull] Determine which metals need to be monitored (i.e., all 
hazardous metals for which Tier III emission limits are lower than PM 
emission limits, assuming PM is pure metal).
    [sbull] Follow the procedures described in SW-846 for preparing 
waste analysis plans for the following tasks:
--Analysis of hazardous waste feedstreams.
--Daily and/or weekly monitoring of kiln dust concentrations for 
continuing compliance.

    (2) Determine the ``safe'' enrichment factor for precompliance. In 
this context, the ``safe'' enrichment factor is a conservatively high 
estimate of the enrichment factor (the ratio of the emitted metal 
concentration to the metal concentration in the collected kiln dust). 
The ``safe'' enrichment factor must be calculated from either 
conservative default values, or engineering judgement.

[[Page 133]]

[GRAPHIC] [TIFF OMITTED] TC01AU92.043

    [sbull] Conservative default values for the ``safe'' enrichment 
factor are as follows:
--SEF=10 for all hazardous metals except mercury. SEF=10 for antimony, 
arsenic, barium, beryllium, cadmium, chromium, lead, silver, and 
thallium.
--SEF=100 for mercury.

    [sbull] Engineering judgement may be used in place of conservative 
default assumptions provided that the engineering judgement is 
defensible and properly documented. The facility must keep a written 
record of all assumptions and calculations necessary to justify the SEF. 
The facility must provide this record to EPA upon request and must be 
prepared to defend these assumptions and calculations.
    Examples of situations where the use of engineering judgement is 
appropriate include:
--Use of data from precompliance tests;
--Use of data from previous compliance tests; and
--Use of data from similar facilities.

    (3) This step does not apply to precompliance procedures.
    (4) Prepare certification of precompliance.

[[Page 134]]

    [sbull] Calculate the ``conservative'' dust metal concentration 
limit (DMCLc) using Equation 5.
    [sbull] Submit certification of precompliance. This certification 
must include precompliance limits for all compliance parameters that 
apply to other boilers and industrial furnaces (i.e., those that do not 
recycle emission control residue back into the furnace) as listed in 
Sec. 266.103(b)(3), except that it is not necessary to set precompliance 
limits on maximum feedrate of each hazardous metal in all combined 
feedstreams.
    [sbull] Furnaces that recycle collected PM back into the furnace 
(and that elect to comply with this method (see Sec. 266.103(c)(3)(ii)) 
are subject to a special precompliance parameter, however. They must 
establish precompliance limits on the maximum concentration of each 
hazardous metal in collected kiln dust (which must be set according to 
the procedures described above).
    (5) Monitor metal concentration in kiln dust for continuing 
compliance, and maintain compliance with all precompliance limits until 
certification of compliance has been submitted.
    [sbull] Metals to be monitored during precompliance testing are 
classified as either ``critical'' or ``noncritical'' metals.
--All metals must initially be classified as ``critical'' metals and be 
monitored on a daily basis.
--A ``critical'' metal may be reclassified as a ``noncritical'' metal if 
its concentration in the kiln dust remains below 10% of its 
``conservative'' kiln dust metal concentration limit for 30 consecutive 
daily samples. ``Noncritical'' metals must be monitored on a weekly 
basis, at a minimum.
--A ``noncritical'' metal must be reclassified as a ``critical'' metal 
if its concentration in the kiln dust is above 10% of its 
``conservative'' kiln dust metal concentration limit for any single 
daily or weekly sample.

    [sbull] It is a violation if the facility fails to analyze the kiln 
dust for any ``critical'' metal on any single day or for any 
``noncritical'' metal during any single week, when hazardous waste is 
burned.
    [sbull] Follow the sampling, compositing, and analytical procedures 
described in this method and in SW-846 as they pertain to the condition 
and accessibility of the kiln dust.
    [sbull] Samples must be collected at least once every 8 hours, and a 
daily composite prepared according to SW-846 procedures.
--At least one composite sample is required. This sample is referred to 
as the ``required'' sample.
--For QA/QC purposes, a facility may elect to collect two or more 
additional samples. These samples are referred to as the ``spare'' 
samples. These additional samples must be collected over the same time 
period and according to the same procedures as those used for the 
``required'' sample.
--Samples for ``critical'' metals must be daily composites.
--Samples for ``noncritical'' metals must be weekly composites, at a 
minimum. These samples can be composites of the original 8-hour samples, 
or they can be composites of daily composite samples.

    [sbull] Analyze the ``required'' sample to determine the 
concentration of each metal.
--This analysis must be completed within 48 hours of the close of the 
sampling period. Failure to meet this schedule is a violation.

    [sbull] If the ``conservative'' kiln dust metal concentration limit 
is exceeded for any metal, refer to Step 8.
    [sbull] If the ``conservative'' kiln dust metal concentration limit 
is not exceeded, continue with the daily and/or weekly monitoring (Step 
5) for the duration of interim status.
    (6) This step does not apply to precompliance procedures.
    (7) This step does not apply to precompliance procedures.
    (8) If the ``conservative'' kiln dust metal concentration limit was 
exceeded for any metal in any single analysis of the ``required'' kiln 
dust sample, the ``spare'' samples corresponding to the same period may 
be analyzed to determine if the exceedance is due to a sampling or 
analysis error.
    [sbull] If no ``spare'' samples were taken, refer to Step 9.
    [sbull] If the average of all the samples for a given day (or week, 
as applicable) (including the ``required'' sample and the ``spare'' 
samples) does not exceed the ``conservative'' kiln dust metal 
concentration limit, no corrective measures are necessary; continue with 
the daily and/or weekly monitoring as described in Step 5.
    [sbull] If the average of all the samples for a given day (or week, 
as applicable) exceeds the ``conservative'' kiln dust metal 
concentration limit, but the average of the ``spare'' samples is below 
the ``conservative'' kiln dust metal concentration limit, apply the Q-
test, described in appendix A, to determine whether the ``required'' 
sample concentration can be judged as an outlier.
--If the ``required'' sample concentration is judged an outlier, no 
corrective measures are necessary; continue with the daily and/or weekly 
monitoring described in Step 5.
--If the ``required'' sample concentration is not judged an outlier, 
refer to Step 10.

    (9) This step does not apply to precompliance procedures.
    (10) Determine if the ``conservative'' kiln dust metal concentration 
limit has been exceeded more than three times in the last 60 days.

[[Page 135]]

    [sbull] If not, log this exceedance and continue with the daily and/
or weekly monitoring (Step 5).
    [sbull] If so, the tests to determine the enrichment factors must be 
repeated (refer to Step 11).
    [sbull] This determination is made separately for each metal; for 
example:
--Three exceedances for each of the ten hazardous metals are allowed 
within any 60-day period.
--Four exceedances of any single metal in any 60-day period is not 
allowed.

    [sbull] This determination should be made daily, beginning on the 
first day of daily monitoring. For example, if four exceedances of any 
single metal occur in the first four days of daily monitoring, do not 
wait until the end of the 60-day period; refer immediately to Step 11.
    (11) A revised certification of precompliance must be submitted to 
the Director (or certification of compliance must be submitted) if: (1) 
More than three exceedances of the ``conservative'' kiln dust metal 
concentration limit occur within any 60 consecutive daily samples; or 
(2) an exceedance of the ``conservative'' kiln dust metal concentration 
limit occurs in any weekly sample.
    [sbull] The facility must notify the Director if a revised 
certification of precompliance must be submitted.
    [sbull] The facility has up to 720 waste-burning hours to submit a 
certification of compliance or a revised certification of precompliance. 
During this period, the feed rate of the metal in violation must be 
reduced by 50%. In the case of a revised certification of precompliance, 
engineering judgement must be used to ensure that the ``conservative'' 
kiln dust metal concentration will not be exceeded. Examples of how this 
goal might be accomplished include:
--Changing equipment or operating procedures to reduce the kiln dust 
metal concentration;
--Changing equipment or operating procedures, or using more detailed 
engineering judgement, to decrease the estimated SEF and thus increase 
the ``conservative'' kiln dust metal concentration limit;
--Increasing the ``conservative'' kiln dust metal concentration limit by 
imposing a stricter PM emissions standard; or
--Increasing the ``conservative'' kiln dust metal concentration limit by 
performing a more detailed risk assessment to increase the metal 
emission limits.

    [sbull] Meanwhile, the facility must continue with daily kiln dust 
metals monitoring (Step 5).

            Appendix A to Appendix IX to Part 266--Statistics

                 A.1 Determination of Enrichment Factor

    After at least 10 initial emissions tests are performed, an 
enrichment factor for each metal must be determined. At the 95% 
confidence level, the enrichment factor, EF95[Lt] s, is based 
on the test results and is statistically determined so there is only a 
5% chance that the enrichment factor at any given time will be larger 
than EF95[Lt]. Similarly, at the 99% confidence level, the 
enrichment factor, EF99[Lt], is statistically determined so 
there is only a 1% chance that the enrichment factor at any given time 
will be larger than EF99[Lt].
    For a large number of samples (n  30), 
EF95[Lt] is based on a normal distribution, and is equal to:
EF95[Lt]=EF+zc [sigma] (1)

where:
[GRAPHIC] [TIFF OMITTED] TC06NO91.018

[GRAPHIC] [TIFF OMITTED] TC06NO91.019

    For a 95% confidence level, zc is equal to 1.645.
    For a small number of samples (n<30), EF95[Lt] is based 
on the t-distribution and is equal to:
EF95[Lt]=EF+tc S (4)

where the standard deviation, S, is defined as:
[GRAPHIC] [TIFF OMITTED] TC06NO91.020

tc is a function of the number of samples and the confidence 
level that is desired. It increases in value as the sample size 
decreases and the confidence level increases. The 95% confidence level 
is used in this method to calculate the ``violation'' kiln dust metal 
concentration limit; and the 99% confidence level is sometimes used to 
calculate the ``conservative'' kiln dust metal concentration limit. 
Values of tc are shown in table A-

[[Page 136]]

1 for various degrees of freedom (degrees of freedom=sample size-1) at 
the 95% and 99% confidence levels. As the sample size approaches 
infinity, the normal distribution is approached.

               A.2 Comparison of Enrichment Factor Groups

    To determine if the enrichment factors measured in the quarterly 
tests are significantly different from the enrichment factors determined 
in the initial Step 2 tests, the t-test is used. In this test, the value 
tmeas:

is compared to tcrit at the desired confidence level. The 95% 
confidence level is used in this method. Values of tcrit are 
shown in table A-1 for various degrees of freedom (degrees of freedom 
n1+n2-2) at the 95% and 99% confidence levels. If 
tmeas is greater then tcrit, it can be concluded 
with 95% confidence that the two groups are not from the same 
population.

                          A.3 Rejection of Data

    If the concentration of any hazardous metal in the ``required'' kiln 
dust sample exceeds the kiln dust metal concentration limit, the 
``spare'' samples are analyzed. If the average of the combined 
``required'' and ``spare'' values is still above the limit, a 
statistical test is used to decide if the upper value can be rejected.
    The ``Q-test'' is used to determine if a data point can be rejected. 
The difference between the questionable result and its neighbor is 
divided by the spread of the entire data set. The resulting ratio, 
Qmeas, is then compared with rejection values that are 
critical for a particular degree of confidence, where Qmeas 
is:
[GRAPHIC] [TIFF OMITTED] TC06NO91.023

The 90% confidence level for data rejection is used in this method. 
Table A-2 provides the values of Qcrit at the 90% confidence 
level. If Qmeas is larger than Qcrit, the data 
point can be discarded. Only one data point from a sample group can be 
rejected using this method.

                           Subpart A--General



Sec. 268.1  Purpose, scope, and applicability.

    (a) This part identifies hazardous wastes that are restricted from 
land disposal and defines those limited circumstances under which an 
otherwise prohibited waste may continue to be land disposed.
    (b) Except as specifically provided otherwise in this part or part 
261 of this chapter, the requirements of this part apply to persons who 
generate or transport hazardous waste and owners and operators of 
hazardous waste treatment, storage, and disposal facilities.
    (c) Restricted wastes may continue to be land disposed as follows:
    (1) Where persons have been granted an extension to the effective 
date of a prohibition under subpart C of this part or pursuant to 
Sec. 268.5, with respect to those wastes covered by the extension;
    (2) Where persons have been granted an exemption from a prohibition 
pursuant to a petition under Sec. 268.6, with respect to those wastes 
and units covered by the petition;
    (3) Wastes that are hazardous only because they exhibit a hazardous 
characteristic, and which are otherwise prohibited under this part, or 
part 148 of this chapter, are not prohibited if the wastes:

identified in 40 CFR part 261, subpart C at the point of injection.
    (4) Wastes that are hazardous only because they exhibit a hazardous 
characteristic, and which are otherwise prohibited under this part, are 
not prohibited if the wastes meet any of the following criteria, unless 
the wastes are subject to a specified method of treatment other than 
DEACT in Sec. 268.40, or are D003 reactive cyanide:
    (i) The wastes are managed in a treatment system which subsequently 
discharges to waters of the U.S. pursuant to a permit issued under 
section 402 of the Clean Water Act; or

wastewaters in paragraph (f) of this section.
    (e) Polychlorinated biphenyls or PCBs are halogenated organic 
compounds defined in accordance with 40 CFR 761.3.
    (f) Wastewaters are wastes that contain less than 1% by weight total 
organic carbon (TOC) and less than 1% by weight total suspended solids 
(TSS).
    (g) Debris means solid material exceeding a 60 mm particle size that 
is intended for disposal and that is: A manufactured object; or plant or 
animal matter; or natural geologic material. However, the following 
materials are not debris: Any material for which a specific treatment 
standard is provided in Subpart D, Part 268, namely lead acid batteries, 
cadmium batteries, and radioactive lead solids; Process residuals such 
as smelter slag and residues from the treatment of waste, wastewater, 
sludges, or air emission residues; and Intact containers of hazardous 
waste that are not ruptured and that retain at least 75% of their 
original volume. A mixture of debris that has not been treated to the 
standards provided by Sec. 268.45 and other material is subject to 
regulation as debris if the mixture is comprised primarily of debris, by 
volume, based on visual inspection.
    (h) Hazardous debris means debris that contains a hazardous waste 
listed in subpart D of part 261 of this chapter, or that exhibits a 
characteristic of hazardous waste identified in subpart C of part 261 of 
this chapter. Any deliberate mixing of prohibited hazardous waste with 
debris that changes its treatment classification (i.e., from waste to 
hazardous debris) is not allowed under the dilution prohibition in 
Sec. 268.3.
    (i) Underlying hazardous constituent means any constituent listed in 
Sec. 268.48, Table UTS--Universal Treatment Standards, except fluoride, 
selenium, sulfides, vanadium, and zinc, which can reasonably be expected 
to be present at the point of generation of the hazardous waste at a 
concentration above the constituent-specific UTS treatment standards.
    (j) Inorganic metal-bearing waste is one for which EPA has 
established treatment standards for metal hazardous constituents, and 
which does not otherwise contain significant organic or cyanide content

XI of this part.
    (k) Soil means unconsolidated earth material composing the 
superficial geologic strata (material overlying bedrock), consisting of 
clay, silt, sand, or gravel size particles as classified by the U.S. 
Natural Resources Conservation Service, or a mixture of such materials 
with liquids, sludges or solids which is inseparable by simple 
mechanical removal processes and is made up primarily of soil by volume 
based on

[[Page 141]]

visual inspection. Any deliberate mixing of prohibited hazardous waste 
with soil that changes its treatment classification (i.e., from waste to 
contaminated soil) is not allowed under the dilution prohibition in 
Sec. 268.3.

Sec. 268.3  Dilution prohibited as a substitute for treatment.

    (a) Except as provided in paragraph (b) of this section, no 
generator, transporter, handler, or owner or operator of a treatment, 
storage, or disposal facility shall in any way dilute a restricted waste 
or the residual from treatment of a restricted waste as a substitute for 
adequate treatment to achieve compliance with subpart D of this part, to 
circumvent the effective date of a prohibition in subpart C of this 
part, to otherwise avoid a prohibition in subpart C of this part, or to 
circumvent a land disposal prohibition imposed by RCRA section 3004.
    (b) Dilution of wastes that are hazardous only because they exhibit 
a characteristic in treatment systems which include land- based units 
which treat wastes subsequently discharged to a water of the United 
States pursuant to a permit issued under section 402 of the Clean Water 
Act (CWA), or which treat wastes in a CWA-equivalent treatment system, 
or which treat wastes for the purposes of pretreatment requirements 
under section 307 of the CWA is not impermissible dilution for purposes 
of this section unless a method other than DEACT has been specified in 
Sec. 268.40 as the treatment standard, or unless the waste is a D003 
reactive cyanide wastewater or nonwastewater.
    (c) Combustion of the hazardous waste codes listed in Appendix XI of 
this part is prohibited, unless the waste, at the point of generation, 
or after any bona fide treatment such as cyanide destruction prior to 
combustion, can be demonstrated to comply with one or more of the 
following criteria (unless otherwise specifically prohibited from 
combustion):
    (1) The waste contains hazardous organic constituents or cyanide at 
levels exceeding the constituent-specific treatment standard found in 
Sec. 268.48;
    (2) The waste consists of organic, debris-like materials (e.g., 
wood, paper, plastic, or cloth) contaminated with an inorganic metal-
bearing hazardous waste;
    (3) The waste, at point of generation, has reasonable heating value 
such as greater than or equal to 5000 BTU per pound;
    (4) The waste is co-generated with wastes for which combustion is a 
required method of treatment;
    (5) The waste is subject to Federal and/or State requirements 
necessitating reduction of organics (including biological agents); or
    (6) The waste contains greater than 1% Total Organic Carbon (TOC).
    (d) It is a form of impermissible dilution, and therefore 
prohibited, to add iron filings or other metallic forms of iron to lead-
containing hazardous wastes in order to achieve any land disposal 
restriction treatment standard for lead. Lead-containing wastes include 
D008 wastes (wastes exhibiting a characteristic due to the presence of 
lead), all characteristic wastes containing lead as an underlying 
hazardous constituent, listed wastes containing lead as a regulated 
constituent, and hazardous media containing any of the aforementioned 
lead-containing wastes.

Sec. 268.4  Treatment surface impoundment exemption.

    (a) Wastes which are otherwise prohibited from land disposal under 
this part may be treated in a surface impoundment or series of 
impoundments provided that:
    (1) Treatment of such wastes occurs in the impoundments;
    (2) The following conditions are met:
    (i) Sampling and testing. For wastes with treatment standards in 
subpart D of this part and/or prohibition levels in subpart C of this 
part or RCRA section 3004(d), the residues from treatment

[[Page 142]]

are analyzed, as specified in Sec. 268.7 or Sec. 268.32, to determine if 
they meet the applicable treatment standards or where no treatment 
standards have been established for the waste, the applicable 
prohibition levels. The sampling method, specified in the waste analysis 
plan under Sec. 264.13 or Sec. 265.13, must be designed such that 
representative samples of the sludge and the supernatant are tested 
separately rather than mixed to form homogeneous samples.
    (ii) Removal. The following treatment residues (including any liquid 
waste) must be removed at least annually; residues which do not meet the 
treatment standards promulgated under subpart D of this part; residues 
which do not meet the prohibition levels established under subpart C of 
this part or imposed by statute (where no treatment standards have been 
established); residues which are from the treatment of wastes prohibited 
from land disposal under subpart C of this part (where no treatment 
standards have been established and no prohibition levels apply); or 
residues from managing listed wastes which are not delisted under 
Sec. 260.22 of this chapter. If the volume of liquid flowing through the 
impoundment or series of impoundments annually is greater than the 
volume of the impoundment or impoundments, this flow-through constitutes 
removal of the supernatant for the purpose of this requirement.
    (iii) Subsequent management. Treatment residues may not be placed in 
any other surface impoundment for subsequent management.
    (iv) Recordkeeping. Sampling and testing and recordkeeping 
provisions of Secs. 264.13 and 265.13 of this chapter apply.
    (3) The impoundment meets the design requirements of Sec. 264.221(c) 
or Sec. 265.221(a) of this chapter, regardless that the unit may not be 
new, expanded, or a replacement, and be in compliance with applicable 
ground water monitoring requirements of subpart F of part 264 or part 
264 of this chapter unless:
    (i) Exempted pursuant to Sec. 264.221 (d) or (e) of this chapter, or 
to Sec. 265.221 (c) or (d) of this chapter; or,
    (ii) Upon application by the owner or operator, the Administrator, 
after notice and an opportunity to comment, has granted a waiver of the 
requirements on the basis that the surface impoundment:
    (A) Has at least one liner, for which there is no evidence that such 
liner is leaking;
    (B) Is located more than one-quarter mile from an underground source 
of drinking water; and
    (C) Is in compliance with generally applicable ground water 
monitoring requirements for facilities with permits; or,
    (iii) Upon application by the owner or operator, the Administrator, 
after notice and an opportunity to comment, has granted a modification 
to the requirements on the basis of a demonstration that the surface 
impoundment is located, designed, and operated so as to assure that 
there will be no migration of any hazardous constituent into ground 
water or surface water at any future time.
    (4) The owner or operator submits to the Regional Administrator a 
written certification that the requirements of Sec. 268.4(a)(3) have 
been met. The following certification is required:

    I certify under penalty of law that the requirements of 40 CFR 
268.4(a)(3) have been met for all surface impoundments being used to 
treat restricted wastes. I believe that the submitted information is 
true, accurate, and complete. I am aware that there are significant 
penalties for submitting false information, including the possibility of 
fine and imprisonment.

    (b) Evaporation of hazardous constituents as the principal means of 
treatment is not considered to be treatment for purposes of an exemption 
under this section.

Sec. 268.5  Procedures for case-by-case extensions to an effective date.

    (a) Any person who generates, treats, stores, or disposes of a 
hazardous waste may submit an application to the Administrator for an 
extension to the effective date of any applicable restriction 
established under subpart C of this part. The applicant must demonstrate 
the following:

[[Page 143]]

    (1) He has made a good-faith effort to locate and contract with 
treatment, recovery, or disposal facilities nationwide to manage his 
waste in accordance with the effective date of the applicable 
restriction established under subpart C of this part;
    (2) He has entered into a binding contractual commitment to 
construct or otherwise provide alternative treatment, recovery (e.g., 
recycling), or disposal capacity that meets the treatment standards 
specified in subpart D or, where treatment standards have not been 
specified, such treatment, recovery, or disposal capacity is protective 
of human health and the environment.
    (3) Due to circumstances beyond the applicant's control, such 
alternative capacity cannot reasonably be made available by the 
applicable effective date. This demonstration may include a showing that 
the technical and practical difficulties associated with providing the 
alternative capacity will result in the capacity not being available by 
the applicable effective date;
    (4) The capacity being constructed or otherwise provided by the 
applicant will be sufficient to manage the entire quantity of waste that 
is the subject of the application;
    (5) He provides a detailed schedule for obtaining required operating 
and construction permits or an outline of how and when alternative 
capacity will be available;
    (6) He has arranged for adequate capacity to manage his waste during 
an extension and has documented in the application the location of all 
sites at which the waste will be managed; and
    (7) Any waste managed in a surface impoundment or landfill during 
the extension period will meet the requirements of paragraph (h)(2) of 
this section.
    (b) An authorized representative signing an application described 
under paragraph (a) of this section shall make the following 
certification:

    I certify under penalty of law that I have personally examined and 
am familiar with the information submitted in this document and all 
attachments and that, based on my inquiry of those individuals 
immediately responsible for obtaining the information, I believe that 
the information is true, accurate, and complete. I am aware that there 
are significant penalties for submitting false information, including 
the possibility of fine and imprisonment.

    (c) After receiving an application for an extension, the 
Administrator may request any additional information which he deems as 
necessary to evaluate the application.
    (d) An extension will apply only to the waste generated at the 
individual facility covered by the application and will not apply to 
restricted waste from any other facility.
    (e) On the basis of the information referred to in paragraph (a) of 
this section, after notice and opportunity for comment, and after 
consultation with appropriate State agencies in all affected States, the 
Administrator may grant an extension of up to 1 year from the effective 
date. The Administrator may renew this extension for up to 1 additional 
year upon the request of the applicant if the demonstration required in 
paragraph (a) of this section can still be made. In no event will an 
extension extend beyond 24 months from the applicable effective date 
specified in subpart C of part 268. The length of any extension 
authorized will be determined by the Administrator based on the time 
required to construct or obtain the type of capacity needed by the 
applicant as described in the completion schedule discussed in paragraph 
(a)(5) of this section. The Administrator will give public notice of the 
intent to approve or deny a petition and provide an opportunity for 
public comment. The final decision on a petition will be published in 
the Federal Register.
    (f) Any person granted an extension under this section must 
immediately notify the Administrator as soon as he has knowledge of any 
change in the conditions certified to in the application.
    (g) Any person granted an extension under this section shall submit 
written progress reports at intervals designated by the Administrator. 
Such reports must describe the overall progress made toward constructing 
or otherwise providing alternative treatment, recovery or disposal 
capacity; must identify any event which may cause or has caused a delay 
in the development of the capacity; and must

[[Page 144]]

summarize the steps taken to mitigate the delay. The Administrator can 
revoke the extension at any time if the applicant does not demonstrate a 
good-faith effort to meet the schedule for completion, if the Agency 
denies or revokes any required permit, if conditions certified in the 
application change, or for any violation of this chapter.
    (h) Whenever the Administrator establishes an extension to an 
effective date under this section, during the period for which such 
extension is in effect:
    (1) The storage restrictions under Sec. 268.50(a) do not apply; and
    (2) Such hazardous waste may be disposed in a landfill or surface 
impoundment only if such unit is in compliance with the technical 
requirements of the following provisions regardless of whether such unit 
is existing, new, or a replacement or lateral expansion.
    (i) The landfill, if in interim status, is in compliance with the 
requirements of subpart F of part 265 and Sec. 265.301 (a), (c), and (d) 
of this chapter; or,
    (ii) The landfill, if permitted, is in compliance with the 
requirements of subpart F of part 264 and Sec. 264.301 (c), (d) and (e) 
of this chapter; or
    (iii) The surface impoundment, if in interim status, is in 
compliance with the requirements of subpart F of part 265, Sec. 265.221 
(a), (c), and (d) of this chapter, and RCRA section 3005(j)(1); or
    (iv) The surface impoundment, if permitted, is in compliance with 
the requirements of subpart F of part 264 and Sec. 264.221 (c), (d) and 
(e) of this chapter; or
    (v) The surface impoundment, if newly subject to RCRA section 
3005(j)(1) due to the promulgation of additional listings or 
characteristics for the identification of hazardous waste, is in 
compliance with the requirements of subpart F of part 265 of this 
chapter within 12 months after the promulgation of additional listings 
or characteristics of hazardous waste, and with the requirements of 
Sec. 265.221 (a), (c) and (d) of this chapter within 48 months after the 
promulgation of additional listings or characteristics of hazardous 
waste. If a national capacity variance is granted, during the period the 
variance is in effect, the surface impoundment, if newly subject to RCRA 
section 3005(j)(1) due to the promulgation of additional listings or 
characteristics of hazardous waste, is in compliance with the 
requirements of subpart F of part 265 of this chapter within 12 months 
after the promulgation of additional listings or characteristics of 
hazardous waste, and with the requirements of Sec. 265.221 (a), (c) and 
(d) of this chapter within 48 months after the promulgation of 
additional listings or characteristics of hazardous waste; or
    (vi) The landfill, if disposing of containerized liquid hazardous 
wastes containing PCBs at concentrations greater than or equal to 50 ppm 
but less than 500 ppm, is also in compliance with the requirements of 40 
CFR 761.75 and parts 264 and 265.
    (i) Pending a decision on the application the applicant is required 
to comply with all restrictions on land disposal under this part once 
the effective date for the waste has been reached.

    (4) A quality assurance and quality control plan that addresses all 
aspects of the demonstration must be approved by the Administrator; and,
    (5) An analysis must be performed to identify and quantify any 
aspects of the demonstration that contribute significantly to 
uncertainty. This analysis must include an evaluation of the 
consequences of predictable future events, including, but not limited 
to, earthquakes, floods, severe storm events, droughts, or other natural 
phenomena.
    (c) Each petition referred to in paragraph (a) of this section must 
include the following:
    (1) A monitoring plan that describes the monitoring program 
installed at and/or around the unit to verify continued compliance with 
the conditions of the variance. This monitoring plan must provide 
information on the monitoring of the unit and/or the environment around 
the unit. The following specific information must be included in the 
plan:
    (i) The media monitored in the cases where monitoring of the 
environment around the unit is required;
    (ii) The type of monitoring conducted at the unit, in the cases

(c)(1) of this section must be in place for a period of time specified 
by the Administrator, as part of his approval of the petition, prior to 
receipt of prohibited waste at the unit.
    (3) The monitoring data collected according to the monitoring plan 
specified under paragraph (c)(1) of this section must be sent to the 
Administrator according to a format and schedule specified and approved 
in the monitoring plan, and
    (4) A copy of the monitoring data collected under the monitoring 
plan specified under paragraph (c)(1) of this section must be kept on-
site at the facility in the operating record.
    (5) The monitoring program specified under paragraph (c)(1) of this 
section meet the following criteria:
    (i) All sampling, testing, and analytical data must be approved by 
the Administrator and must provide data that is accurate and 
reproducible.
    (ii) All estimation and monitoring techniques must be approved by 
the Administrator.
    (iii) A quality assurance and quality control plan addressing all

    (d) Each petition must be submitted to the Administrator.
    (e) After a petition has been approved, the owner or operator must 
report any changes in conditions at the unit and/or the environment 
around the unit that significantly depart from the conditions described 
in the variance and affect the potential for migration of hazardous 
constituents from the units as follows:
    (1) If the owner or operator plans to make changes to the unit 
design, construction, or operation, such a change must be proposed, in 
writing, and the

[[Page 146]]

owner or operator must submit a demonstration to the Administrator at 
least 30 days prior to making the change. The Administrator will 
determine whether the proposed change invalidates the terms of the 
petition and will determine the appropriate response. Any change must be 
approved by the Administrator prior to being made.
    (2) If the owner or operator discovers that a condition at the site 
which was modeled or predicted in the petition does not occur as 
predicted, this change must be reported, in writing, to the 
Administrator within 10 days of discovering the change. The 
Administrator will determine whether the reported change from the terms 
of the petition requires further action, which may include termination 
of waste acceptance and revocation of the petition, petition 
modifications, or other responses.
    (f) If the owner or operator determines that there is migration of 
hazardous constituent(s) from the unit, the owner or operator must:
    (1) Immediately suspend receipt of prohibited waste at the unit, and
    (2) Notify the Administrator, in writing, within 10 days of the 
determination that a release has occurred.
    (3) Following receipt of the notification the Administrator will 
determine, within 60 days of receiving notification, whether the owner 
or operator can continue to receive prohibited waste in the unit and 
whether the variance is to be revoked. The Administrator shall also 
determine whether further examination of any migration is warranted 
under applicable provisions of part 264 or part 265.
    (g) Each petition must include the following statement signed by the 
petitioner or an authorized representative:


I certify under penalty of law that I have personally examined and am 
familiar with the information submitted in this petition and all 
attached documents, and that, based on my inquiry of those individuals 
immediately responsible for obtaining the information, I believe that 
submitted information is true, accurate, and complete. I am aware that 
there are significant penalties for submitting false information, 
including the possibility of fine and imprisonment.

    (h) After receiving a petition, the Administrator may request any 
additional information that reasonably may be required to evaluate the 
demonstration.
    (i) If approved, the petition will apply to land disposal of the 
specific restricted waste at the individual disposal unit described in 
the demonstration and will not apply to any other restricted waste at 
that disposal unit, or to that specific restricted waste at any other 
disposal unit.
    (j) The Administrator will give public notice in the Federal 
Register of the intent to approve or deny a petition and provide an 
opportunity for public comment. The final decision on a petition will be 
published in the Federal Register.
    (k) The term of a petition granted under this section shall be no 
longer than the term of the RCRA permit if the disposal unit is 
operating under a RCRA permit, or up to a maximum of 10 years from the 
date of approval provided under paragraph (g) of this section if the 
unit is operating under interim status. In either case, the term of the 
granted petition shall expire upon the termination or denial of a RCRA 
permit, or upon the termination of interim status or when the volume 
limit of waste to be land disposed during the term of petition is 
reached.
    (l) Prior to the Administrator's decision, the applicant is required 
to comply with all restrictions on land disposal under this part once 
the effective date for the waste has been reached.
    (m) The petition granted by the Administrator does not relieve the 
petitioner of his responsibilities in the management of hazardous waste 
under 40 CFR part 260 through part 271.
    (n) Liquid hazardous wastes containing polychlorinated biphenyls at 
concentrations greater than or equal to 500 ppm are not eligible for an 
exemption under this section.

Sec. 268.7  Testing, tracking, and recordkeeping requirements for generators, treaters, and disposal facilities.

    (a) Requirements for generators: (1) A generator of hazardous waste 
must determine if the waste has to be treated before it can be land 
disposed. This is done by determining if the hazardous waste meets the 
treatment standards in Sec. 268.40, Sec. 268.45, or Sec. 268.49. This 
determination can be made in either of two ways: testing the waste or 
using knowledge of the waste. If the generator tests the waste, testing 
would normally determine the total concentration of hazardous 
constituents, or the concentration of hazardous constituents in an 
extract of the waste obtained using test method 1311 in ``Test Methods 
of Evaluating Solid Waste, Physical/Chemical Methods,'' EPA Publication 
SW-846, as referenced in Sec. 260.11 of this chapter, depending on 
whether the treatment standard for the waste is expressed as a total 
concentration or concentration of hazardous constituent in the waste's 
extract. In addition, some hazardous wastes must be treated by 
particular treatment methods before they can be land disposed and some 
soils are contaminated by such hazardous wastes. These treatment 
standards are also found in Sec. 268.40, and are described in detail in 
Sec. 268.42, Table 1. These wastes, and solids contaminated with such 
wastes, do not need to be tested (however, if they are in a waste 
mixture, other wastes with concentration level treatment standards would 
have to be tested). If a generator determines they are managing a waste 
or soil contamination with a waste, that displays a hazardous 
characteristic of ignitability, corrosivity, reactivity, or toxicity, 
they must comply with the special requirements of Sec. 268.9 of this 
part in addition to any applicable requirements in this section.
    (2) If the waste or contaminated soil does not meet the treatment 
standard: With the initial shipment of waste to each treatment or 
storage facility, the generator must send a one-time written notice to 
each treatment or storage facility receiving the waste, and place a copy 
in the file. The notice must include the information in column 
``268.7(a)(2)'' of the Generator Paperwork Requirements Table in 
Sec. 268.7(a)(4). No further notification is necessary until such time 
that the waste or facility change, in which case a new notification must 
be sent and a copy placed in the generator's file.
    (i) For contaminated soil, the following certification statement 
should be included, signed by an authorized representative:

    I certify under penalty of law that I personally have examined this 
contaminated soil and it [does/does not] contain listed hazardous waste 
and [does/does not] exhibit a characteristic of hazardous waste and 
requires treatment to meet the soil treatment standards as provided by 
268.49(c).

    (ii) [Reserved]
    (3) If the waste or contaminated soil meets the treatment standard 
at the original point of generation:
    (i) With the initial shipment of waste to each treatment, storage, 
or disposal facility, the generator must send a one-time written notice 
to each treatment, storage, or disposal facility receiving the waste, 
and place a copy in the file. The notice must include the information 
indicated in column ``268.7(a)(3)'' of the Generator Paperwork 
Requirements Table in Sec. 268.7(a)(4) and the following certification 
statement, signed by an authorized representative:

    I certify under penalty of law that I personally have examined and 
am familiar with the waste through analysis and testing or through 
knowledge of the waste to support this certification that the waste 
complies with the treatment standards specified in 40 CFR part 268 
subpart D. I believe that the information I submitted is true, accurate, 
and complete. I am aware that there are significant penalties for 
submitting a false certification, including the possibility of a fine 
and imprisonment.

    (ii) For contaminated soil, with the initial shipment of wastes to 
each treatment, storage, or disposal facility, the generator must send a 
one-time written notice to each facility receiving the waste and place a 
copy in the file. The notice must include the information in 
``268.7(a)(3) of the Generator Paperwork Requirements Table in 
Sec. 268.7(a)(4).
    (iii) If the waste changes, the generator must send a new notice and 
certification to the receiving facility, and

[[Page 148]]

place a copy in their files. Generators of hazardous debris excluded 
from the definition of hazardous waste under Sec. 261.3(f) of this 
chapter are not subject to these requirements.
    (4) For reporting, tracking, and recordkeeping when exceptions allow 
certain wastes or contaminated soil that do not meet the treatment 
standards to be land disposed: There are certain exemptions from the 
requirement that hazardous wastes or contaminated soil meet treatment 
standards before they can be land disposed. These include, but are not 
limited to case-by-case extensions under Sec. 268.5, disposal in a no-
migration unit under Sec. 268.6, or a national capacity variance or 
case-by-case capacity variance under subpart C of this part. If a 
generator's waste is so exempt, then with the initial shipment of waste, 
the generator must send a one-time written notice to each land disposal 
facility receiving the waste. The notice must include the information 
indicated in column ``268.7(a)(4)'' of the Generator Paperwork 
Requirements Table below. If the waste changes, the generator must send 
a new notice to the receiving facility, and place a copy in their files.

----------------------------------------------------------------------------------------------------------------

    (5) If a generator is managing and treating prohibited waste or 
contaminated soil in tanks, containers, or containment buildings 
regulated under 40 CFR 262.34 to meet applicable LDR treatment standards 
found at Sec. 268.40, the generator must develop and follow a written 
waste analysis plan which describes the procedures they will carry out 
to comply with the treatment standards. (Generators treating hazardous 
debris under the alternative treatment standards of Table 1, 
Sec. 268.45, however, are not subject to these waste analysis 
requirements.) The plan must be kept on site in the generator's records, 
and the following requirements must be met:
    (i) The waste analysis plan must be based on a detailed chemical and 
physical analysis of a representative sample of the prohibited waste(s) 
being treated, and contain all information necessary to treat the 
waste(s) in accordance with the requirements of this part, including the 
selected testing frequency.
    (ii) Such plan must be kept in the facility's on-site files and made 
available to inspectors.
    (iii) Wastes shipped off-site pursuant to this paragraph must comply 
with

[[Page 149]]

the notification requirements of Sec. 268.7(a)(3).
    (6) If a generator determines that the waste or contaminated soil is 
restricted based solely on his knowledge of the waste, all supporting 
data used to make this determination must be retained on-site in the 
generator's files. If a generator determines that the waste is 
restricted based on testing this waste or an extract developed using the 
test method 1311 in ``Test Methods for Evaluating Solid Waste, Physical/
Chemical Methods,'' EPA Publication SW-846, as referenced in Sec. 260.11 
of this chapter, and all waste analysis data must be retained on-site in 
the generator's files.
    (7) If a generator determines that he is managing a prohibited waste 
that is excluded from the definition of hazardous or solid waste or is 
exempted from Subtitle C regulation under 40 CFR 261.2 through 261.6 
subsequent to the point of generation (including deactivated 
characteristic hazardous wastes managed in wastewater treatment systems 
subject to the Clean Water Act (CWA) as specified at 40 CFR 261.4(a)(2) 
or that are CWA-equivalent, or are managed in an underground injection 
well regulated by the SDWA), he must place a one-time notice describing 
such generation, subsequent exclusion from the definition of hazardous 
or solid waste or exemption from RCRA Subtitle C regulation, and the 
disposition of the waste, in the facility's on-site files.
    (8) Generators must retain on-site a copy of all notices, 
certifications, waste analysis data, and other documentation produced 
pursuant to this section for at least three years from the date that the 
waste that is the subject of such documentation was last sent to on-site 
or off-site treatment, storage, or disposal. The three year record 
retention period is automatically extended during the course of any 
unresolved enforcement action regarding the regulated activity or as 
requested by the Administrator. The requirements of this paragraph apply 
to solid wastes even when the hazardous characteristic is removed prior 
to disposal, or when the waste is excluded from the definition of 
hazardous or solid waste under 40 CFR 261.2 through 261.6, or exempted 
from Subtitle C regulation, subsequent to the point of generation.
    (9) If a generator is managing a lab pack containing hazardous 
wastes and wishes to use the alternative treatment standard for lab 
packs found at Sec. 268.42(c):
    (i) With the initial shipment of waste to a treatment facility, the 
generator must submit a notice that provides the information in column 
``Sec. 268.7(a)(9)'' in the Generator Paperwork Requirements Table of 
paragraph (a)(4) of this section, and the following certification. The 
certification, which must be signed by an authorized representative and 
must be placed in the generator's files, must say the following:

    I certify under penalty of law that I personally have examined and 
am familiar with the waste and that the lab pack contains only wastes 
that have not been excluded under appendix IV to 40 CFR part 268 and 
that this lab pack will be sent to a combustion facility in compliance 
with the alternative treatment standards for lab packs at 40 CFR 
268.42(c). I am aware that there are significant penalties for 
submitting a false certification, including the possibility of fine or 
imprisonment.

    (ii) No further notification is necessary until such time that the 
wastes in the lab pack change, or the receiving facility changes, in 
which case a new notice and certification must be sent and a copy placed 
in the generator's file.
    (iii) If the lab pack contains characteristic hazardous wastes 
(D001-D043), underlying hazardous constituents (as defined in 
Sec. 268.2(i)) need not be determined.
    (iv) The generator must also comply with the requirements in 
paragraphs (a)(6) and (a)(7) of this section.
    (10) Small quantity generators with tolling agreements pursuant to 
40 CFR 262.20(e) must comply with the applicable notification and 
certification requirements of paragraph (a) of this section for the 
initial shipment of the waste subject to the agreement. Such generators 
must retain on-site a copy of the notification and certification, 
together with the tolling agreement, for at least three years after 
termination or expiration of the agreement. The three-year record 
retention period is automatically extended during the

[[Page 150]]

course of any unresolved enforcement action regarding the regulated 
activity or as requested by the Administrator.
    (b) Treatment facilities must test their wastes according to the 
frequency specified in their waste analysis plans as required by 40 CFR 
264.13 (for permitted TSDs) or 40 CFR 265.13 (for interim status 
facilities). Such testing must be performed as provided in paragraphs 
(b)(1), (b)(2) and (b)(3) of this section.
    (1) For wastes or contaminated soil with treatment standards 
expressed in the waste extract (TCLP), the owner or operator of the 
treatment facility must test an extract of the treatment residues, using 
test method 1311 (the Toxicity Characteristic Leaching Procedure, 
described in ``Test Methods for Evaluating Solid Waste, Physical/
Chemical Methods,'' EPA Publication SW-846 as incorporated by reference 
in Sec. 260.11 of this chapter) to assure that the treatment residues 
extract meet the applicable treatment standards.
    (2) For wastes or contaminated soil with treatment standards 
expressed as concentrations in the waste, the owner or operator of the 
treatment facility must test the treatment residues (not an extract of 
such residues) to assure that they meet the applicable treatment 
standards.
    (3) A one-time notice must be sent with the initial shipment of 
waste or contaminated soil to the land disposal facility. A copy of the 
notice must be placed in the treatment facility's file.
    (i) No further notification is necessary until such time that the 
waste or receiving facility change, in which case a new notice must be 
sent and a copy placed in the treatment facility's file.
    (ii) The one-time notice must include these requirements:

5. For contaminated soil subject to LDRs as provided in   [b
 268.49(a), the constituents subject to treatment as      <]
 described in 268.49(d) and the following statement,
 ``this contaminated soil [does/does not] exhibit a
 characteristic of hazardous waste and [is subject to/
 complies with] the soil treatment standards as provided
 by 268.49(c)...........................................
6. A certification is needed (see applicable section for  [b
 exact wording).........................................  <]
------------------------------------------------------------------------

    (4) The treatment facility must submit a one-time certification 
signed by an authorized representative with the initial shipment of 
waste or treatment residue of a restricted waste to the land disposal 
facility. The certification must state:

    I certify under penalty of law that I have personally examined and 
am familiar with the treatment technology and operation of the treatment 
process used to support this certification. Based on my inquiry of those 
individuals immediately responsible for obtaining this information, I 
believe that the treatment process has been operated and maintained 
properly so as to comply with the treatment standards specified in 40 
CFR 268.40 without impermissible dilution of the prohibited waste. I am 
aware there are significant penalties for submitting a false 
certification, including the possibility of fine and imprisonment.


A certification is also necessary for contaminated soil and it must 
state:

    I certify under penalty of law that I have personally examined and 
am familiar with the treatment technology and operation of the treatment 
process used to support this certification and believe that it has been 
maintained and operated properly so as to comply with treatment 
standards specified in 40 CFR 268.49 without impermissible dilution of 
the prohibited wastes. I am aware there are significant penalties for 
submitting a false certification, including the possibility of fine and 
imprisonment.

    (i) A copy of the certification must be placed in the treatment 
facility's on-site files. If the waste or treatment

[[Page 151]]

residue changes, or the receiving facility changes, a new certification 
must be sent to the receiving facility, and a copy placed in the file.
    (ii) Debris excluded from the definition of hazardous waste under 
Sec. 261.3(e) of this chapter (i.e., debris treated by an extraction or 
destruction technology provided by Table 1, Sec. 268.45, and debris that 
the Director has determined does not contain hazardous waste), however, 
is subject to the notification and certification requirements of 
paragraph (d) of this section rather than the certification requirements 
of this paragraph.
    (iii) For wastes with organic constituents having treatment 
standards expressed as concentration levels, if compliance with the 
treatment standards is based in whole or in part on the analytical 
detection limit alternative specified in Sec. 268.40(d), the 
certification, signed by an authorized representative, must state the 
following:

    I certify under penalty of law that I have personally examined and 
am familiar with the treatment technology and operation of the treatment 
process used to support this certification. Based on my inquiry of those 
individuals immediately responsible for obtaining this information, I 
believe that the nonwastewater organic constituents have been treated by 
combustion units as specified in 268.42, Table 1. I have been unable to 
detect the nonwastewater organic constituents, despite having used best 
good-faith efforts to analyze for such constituents. I am aware there 
are significant penalties for submitting a false certification, 
including the possibility of fine and imprisonment.

    (iv) For characteristic wastes that are subject to the treatment 
standards in Sec. 268.40 (other than those expressed as a method of 
treatment), or Sec. 268.49, and that contain underlying hazardous 
constituents as defined in Sec. 268.2(i); if these wastes are treated 
on-site to remove the hazardous characteristic; and are then sent off-
site for treatment of underlying hazardous constituents, the 
certification must state the following:

    I certify under penalty of law that the waste has been treated in 
accordance with the requirements of 40 CFR 268.40 or 268.49 to remove 
the hazardous characteristic. This decharacterized waste contains 
underlying hazardous constituents that require further treatment to meet 
treatment standards. I am aware that there are significant penalties for 
submitting a false certification, including the possibility of fine and 
imprisonment.

    (v) For characteristic wastes that contain underlying hazardous 
constituents as defined Sec. 268.2(i) that are treated on-site to remove 
the hazardous characteristic to treat underlying hazardous constituents 
to levels in Sec. 268.48 Universal Treatment Standards, the 
certification must state the following:

    I certify under penalty of law that the waste has been treated in 
accordance with the requirements of 40 CFR 268.40 to remove the 
hazardous characteristic and that underlying hazardous constituents, as 
defined in Sec. 268.2(i) have been treated on-site to meet the 
Sec. 268.48 Universal Treatment Standards. I am aware that there are 
significant penalties for submitting a false certification, including 
the possibility of fine and imprisonment.

    (5) If the waste or treatment residue will be further managed at a 
different treatment, storage, or disposal facility, the treatment, 
storage, or disposal facility sending the waste or treatment residue 
off-site must comply with the notice and certification requirements 
applicable to generators under this section.
    (6) Where the wastes are recyclable materials used in a manner 
constituting disposal subject to the provisions of Sec. 268.20(b) 
regarding treatment standards and prohibition levels, the owner or 
operator of a treatment facility (i.e., the recycler) is not required to 
notify the receiving facility, pursuant to paragraph (b)(3) of this 
section. With each shipment of such wastes the owner or operator of the 
recycling facility must submit a certification described in paragraph 
(b)(4) of this section, and a notice which includes the information 
listed in paragraph (b)(3) of this section (except the manifest number) 
to the Regional Administrator, or his delegated representative. The 
recycling facility also must keep records of the name and location of 
each entity receiving the hazardous waste-derived product.
    (c) Except where the owner or operator is disposing of any waste 
that is a recyclable material used in a manner constituting disposal 
pursuant to 40 CFR 266.20(b), the owner or operator of any land disposal 
facility disposing any waste subject to restrictions under this part 
must:

[[Page 152]]

    (1) Have copies of the notice and certifications specified in 
paragraph (a) or (b) of this section.
    (2) Test the waste, or an extract of the waste or treatment residue 
developed using test method 1311 (the Toxicity Characteristic Leaching 
Procedure), described in ``Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods,'' EPA Publication SW-846 as incorporated by 
reference in Sec. 260.11 of this chapter), to assure that the wastes or 
treatment residues are in compliance with the applicable treatment 
standards set forth in subpart D of this part. Such testing must be 
performed according to the frequency specified in the facility's waste 
analysis plan as required by Sec. 264.13 or Sec. 265.13 of this chapter.
    (d) Generators or treaters who first claim that hazardous debris is 
excluded from the definition of hazardous waste under Sec. 261.3(e) of 
this chapter (i.e., debris treated by an extraction or destruction 
technology provided by Table 1, Sec. 268.45, and debris that the EPA 
Regional Administrator (or his designated representative) or State 
authorized to implement part 268 requirements has determined does not 
contain hazardous waste) are subject to the following notification and 
certification requirements:
    (1) A one-time notification, including the following information, 
must be submitted to the EPA Regional hazardous waste management 
division director (or his designated representative) or State authorized 
to implement part 268 requirements, or State authorized to implement 
part 268 requirements:
    (2) The notification must be updated if the debris is shipped to a 
different facility, and, for debris excluded under Sec. 261.2(e)(1) of 
this chapter, if a different type of debris is treated or if a different 
technology is used to treat the debris.
    (3) For debris excluded under Sec. 261.3(e)(1) of this chapter, the 
owner or operator of the treatment facility must document and certify 
compliance with the treatment standards of Table 1, Sec. 268.45, as 
follows:
    (i) Records must be kept of all inspections, evaluations, and 
analyses of treated debris that are made to determine compliance with 
the treatment standards;
    (ii) Records must be kept of any data or information the treater 
obtains during treatment of the debris that identifies key operating 
parameters of the treatment unit; and
    (iii) For each shipment of treated debris, a certification of 
compliance with the treatment standards must be signed by an authorized 
representative and placed in the facility's files. The certification 
must state the following: ``I certify under penalty of law that the 
debris has been treated in accordance with the requirements of 40 CFR

false certification, including the possibility of fine and 
imprisonment.''
    (e) Generators and treaters who first receive from EPA or an 
authorized state a determination that a given contaminated soil subject 
to LDRs as provided in Sec. 268.49(a) no longer contains a listed 
hazardous waste and generators and treaters who first determine that a 
contaminated soil subject to LDRs as provided in Sec. 268.49(a) no 
longer exhibits a characteristic of hazardous waste must:
    (1) Prepare a one-time only documentation of these determinations 
including all supporting information; and,
    (2) Maintain that information in the facility files and other 
records for a minimum of three years.

Sec. 268.8  [Reserved]



Sec. 268.9  Special rules regarding wastes that exhibit a characteristic.

    (a) The initial generator of a solid waste must determine each EPA 
Hazardous Waste Number (waste code) applicable to the waste in order to 
determine the applicable treatment standards under subpart D of this 
part. For purposes of part 268, the waste will carry the waste code for 
any applicable listed waste (Part 261, Subpart D). In

[[Page 153]]

addition, where the waste exhibits a characteristic, the waste will 
carry one or more of the characteristic waste codes (Part 261, Subpart 
C), except when the treatment standard for the listed waste operates in 
lieu of the treatment standard for the characteristic waste, as 
specified in paragraph (b) of this section. If the generator determines 
that their waste displays a hazardous characteristic (and is not D001 
nonwastewaters treated by CMBST, RORGS, OR POLYM of Sec. 268.42, Table 
1), the generator must determine the underlying hazardous constituents 
(as defined at Sec. 268.2(i)) in the characteristic waste.
    (b) Where a prohibited waste is both listed under 40 CFR part 261, 
subpart D and exhibits a characteristic under 40 CFR part 261, subpart 
C, the treatment standard for the waste code listed in 40 CFR part 261, 
subpart D will operate in lieu of the standard for the waste code under 
40 CFR part 261, subpart C, provided that the treatment standard for the 
listed waste includes a treatment standard for the constituent that 
causes the waste to exhibit the characteristic. Otherwise, the waste 
must meet the treatment standards for all applicable listed and 
characteristic waste codes.
    (c) In addition to any applicable standards determined from the 
initial point of generation, no prohibited waste which exhibits a 
characteristic under 40 CFR part 261, subpart C may be land disposed 
unless the waste complies with the treatment standards under subpart D 
of this part.
    (d) Wastes that exhibit a characteristic are also subject to 
Sec. 268.7 requirements, except that once the waste is no longer 
hazardous, a one-time notification and certification must be placed in 
the generators or treaters files and sent to the EPA region or 
authorized state. The notification and certification that is placed in 
the generators or treaters files must be updated if the process or 
operation generating the waste changes and/or if the subtitle D facility 
receiving the waste changes. However, the generator or treater need only 
notify the EPA region or an authorized state on an annual basis if such 
changes occur. Such notification and certification should be sent to the 
EPA region or authorized state by the end of the calendar year, but no 
later that December 31.
    (1) The notification must include the following information:
    (i) Name and address of the RCRA Subtitle D facility receiving the 
waste shipment; and
    (ii) A description of the waste as initially generated, including 
the applicable EPA hazardous waste code(s), treatability group(s), and 
underlying hazardous constituents (as defined in Sec. 268.2(i)), unless 
the waste will be treated and monitored for all underlying hazardous 
constituents. If all underlying hazardous constituents will be treated 
and monitored, there is no requirement to list any of the underlying 
hazardous constituents on the notice.
    (2) The certification must be signed by an authorized representative 
and must state the language found in Sec. 268.7(b)(4).
    (i) If treatment removes the characteristic but does not meet 
standards applicable to underlying hazardous constituents, then the 
certification found in Sec. 268.7(b)(4)(iv) applies.
    (ii) [Reserved]

                     Subpart D--Treatment Standards



Sec. 268.40  Applicability of treatment standards.

    (a) A prohibited waste identified in the table ``Treatment Standards 
for Hazardous Wastes'' may be land disposed only if it meets the 
requirements found in the table. For each waste, the table identifies 
one of three types of treatment standard requirements:
    (1) All hazardous constituents in the waste or in the treatment 
residue must be at or below the values found in the table for that waste 
(``total waste standards''); or
    (2) The hazardous constituents in the extract of the waste or in the 
extract of the treatment residue must be at or below the values found in 
the table (``waste extract standards''); or
    (3) The waste must be treated using the technology specified in the 
table (``technology standard''), which are described in detail in 
Sec. 268.42, Table 1--Technology Codes and Description of Technology-
Based Standards.
    (b) For wastewaters, compliance with concentration level standards 
is based on maximums for any one day, except for D004 through D011 
wastes for which the previously promulgated treatment standards based on 
grab samples remain in effect. For all nonwastewaters, compliance with 
concentration level standards is based on grab sampling. For wastes 
covered by the waste extract standards, the test Method 1311, the 
Toxicity Characteristic Leaching Procedure found in ``Test Methods for 
Evaluating Solid Waste, Physical/Chemical Methods'', EPA Publication SW-
846, as incorporated by reference in Sec. 260.11, must be used to 
measure compliance. An exception is made for D004 and D008, for which 
either of two test methods may be used: Method 1311, or Method 1310, the 
Extraction Procedure Toxicity Test. For wastes covered by a technology 
standard, the wastes may be land disposed after being treated using that 
specified technology or an equivalent treatment technology approved by 
the Administrator under the procedures set forth in Sec. 268.42(b).
    (c) When wastes with differing treatment standards for a constituent 
of concern are combined for purposes of treatment, the treatment residue 
must meet the lowest treatment standard for the constituent of concern.
    (d) Notwithstanding the prohibitions specified in paragraph (a) of 
this section, treatment and disposal facilities may demonstrate (and 
certify pursuant to 40 CFR 268.7(b)(5)) compliance with the treatment 
standards for organic constituents specified by a footnote in the table 
``Treatment Standards for Hazardous Wastes'' in this section, provided 
the following conditions are satisfied:
    (1) The treatment standards for the organic constituents were 
established based on incineration in units operated in accordance with 
the technical requirements of 40 CFR part 264, subpart O, or based on 
combustion in fuel substitution units operating in accordance with 
applicable technical requirements;
    (2) The treatment or disposal facility has used the methods 
referenced in paragraph (d)(1) of this section to treat the organic 
constituents; and
    (3) The treatment or disposal facility may demonstrate compliance 
with organic constituents if good-faith analytical efforts achieve 
detection limits for the regulated organic constituents that do not 
exceed the treatment standards specified in this section by an order of 
magnitude.
    (e) For characteristic wastes (D001-D043) that are subject to 
treatment standards in the following table ``Treatment Standards for 
Hazardous Wastes,'' and are not managed in a wastewater treatment system 
that is regulated under the Clean Water Act (CWA), that is CWA-
equivalent, or that is injected into a Class I nonhazardous deep 
injection well, all underlying hazardous constituents (as defined in 
Sec. 268.2(i)) must meet Universal Treatment Standards, found in 
Sec. 268.48, Table Universal Treatment Standards, prior to land disposal 
as defined in Sec. 268.2(c) of this part.

[[Page 161]]

    (f) The treatment standards for F001-F005 nonwastewater constituents 
carbon disulfide, cyclohexanone, and/or methanol apply to wastes which 
contain only one, two, or three of these constituents. Compliance is 
measured for these constituents in the waste extract from test Method 
1311, the Toxicity Characteristic Leaching Procedure found in ``Test 
Methods for Evaluating Solid Waste, Physical/Chemical Methods'', EPA 
Publication SW-846, as incorporated by reference in Sec. 260.11. If the 
waste contains any of these three constituents along with any of the 
other 25 constituents found in F001-F005, then compliance with treatment 
standards for carbon disulfide, cyclohexanone, and/or methanol are not 
required.
    (g) Between August 26, 1996 and March 4, 1999 the treatment 
standards for the wastes specified in 40 CFR 261.32 as EPA Hazardous 
Waste numbers K156-K161; and in 40 CFR 261.33 as EPA Hazardous Waste 
numbers P127, P128, P185, P188-P192, P194, P196-P199, P201-P205, U271, 
U277-U280, U364-U367, U372, U373, U375-U379, U381-U387, U389-U396, U400-
U404, U407, and U409-U411; and soil contaminated with these wastes; may 
be satisfied by either meeting the constituent concentrations presented 
in the table ``Treatment Standards for Hazardous Wastes'' in this 
section, or by treating the waste by the following technologies: 
combustion, as defined by the technology code CMBST at Sec. 268.42 Table 
1, for nonwastewaters; and, biodegradation as definded by the technology 
code BIODG, carbon adsorption as defined by the technology code CARBN, 
chemical oxidation as defined by the technology code CHOXD, or 
combustion as defined as technology code CMBST at Sec. 268.42 Table 1, 
for wastewaters.
    (h) Prohibited D004-D011 mixed radioactive wastes and mixed 
radioactive listed wastes containing metal constituents, that were 
previously treated by stabilization to the treatment standards in effect 
at that time and then put into storage, do not have to be re-treated to 
meet treatment standards in this section prior to land disposal.
    (i) Zinc micronutrient fertilizers that are produced for the general 
public's use and that are produced from or contain recycled 
characteristic hazardous wastes (D004-D011) are subject to the 
applicable treatment standards in Sec. 268.41 contained in the 40 CFR, 
parts 260 to 299, edition revised as of July 1, 1990.
    (j) Effective September 4, 1998, the treatment standards for the 
wastes specified in 40 CFR 261.33 as EPA Hazardous Waste numbers P185, 
P191, P192, P197, U364, U394, and U395 may be satisfied by either 
meeting the constituent concentrations presented in the table 
``Treatment Standards for Hazardous Wastes'' in this section, or by 
treating the waste by the following technologies: combustion, as defined 
by the technology code CMBST at Sec. 268.42 Table 1 of this Part, for 
nonwastewaters; and, biodegradation as defined by the technology code 
BIODG, carbon adsorption as defined by the technology code CARBN, 
chemical oxidation as defined by the technology code CHOXD, or 
combustion as defined as technology code CMBST at Sec. 268.42 Table 1 of 
this Part, for wastewaters.
