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.

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.

(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.

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
prescribed in paragraph (e)(6) of this section;

design or operating procedures;
(E) Minimum combustion gas temperature measured at a location
indicative of combustion chamber temperature, measured and specified as
prescribed in paragraph (e)(6) of this section;
(F) An appropriate indicator of combustion gas velocity, measured
and specified as prescribed in paragraph (e)(6) of this section, unless
documentation is provided under Sec. 270.66 of this chapter
demonstrating adequate combustion gas residence time; and
(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

(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.

FR 42512, 42514, Aug. 27, 1991]
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:

best engineering judgment or the procedures specified in appendix IX of
this part.
(C) For industrial furnaces that recycle collected particulate
matter (PM) back into the furnace and that will certify compliance with
the metals emissions standards under paragraph (c)(3)(ii)(A), the

(4) Operating requirements for furnaces that recycle PM. Owners and
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

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

(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

(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:

(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

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:

(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.

[[Page 38]]
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.
[[Page 42]]
(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).

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:
(A) Design standard(s), if available, according to which the direct
transfer equipment was constructed;
(B) Hazardous characteristics of the waste(s) that have been or will
be handled;
(C) Existing corrosion protection measures;
(D) Documented age of the equipment, if available, (otherwise, an
estimate of the age); and
(E) Results of a leak test or other integrity examination such that
the effects of temperature variations, vapor pockets, cracks, leaks,
corrosion, and erosion are accounted for.
(iii) If, as a result of the assessment specified above, the direct
transfer equipment is found to be leaking or unfit for use, the owner or
operator shall comply with the requirements of Secs. 265.196 (a) and (b)
of this chapter.
(3) Inspections and recordkeeping. (i) The owner or operator must
inspect at least once each operating hour when hazardous waste is being
transferred from the transport vehicle (container) to the boiler or
industrial furnace:
(A) Overfill/spill control equipment (e.g., waste-feed cutoff
systems, bypass systems, and drainage systems) to ensure that it is in
good working order;
(B) The above ground portions of the direct transfer equipment to
detect corrosion, erosion, or releases of waste (e.g., wet spots, dead
vegetation); and

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.

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

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

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.

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.

[[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

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?
(a) In addition to those records required by your NRC or NRC
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.

be followed to obtain EPA approval to add a person to the federal USFRS
XL Project. USFRS and a proposed generator must also comply with the
procedures identified by the MPCA, and appropriate County Agencies. A
person may not be added to the federal USFRS XL Project unless it has
the approval of EPA, MPCA and as appropriate the County Agencies.
(b) USFRS is the only entity which may propose to add a person as a
generator to the USFRS XL Project. USFRS may propose to EPA to add
persons to the USFRS XL Project at any time provided, USFRS complies
with the requirements of this section. Prior to being considered a USFRS
XL waste generator, a person must first be approved as a USFRS XL waste
approved customer. Only a USFRS XL waste approved customer may become a
USFRS XL waste generator. A person becomes a USFRS XL waste generator
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.
Sec. 266.404 USFRS requirements related to the development, use and content of USFRS XL Waste Training Module.
(a) USFRS will develop, implement and maintain a USFRS XL Waste
Training Module. USFRS will provide this training module to every person
who applies for participation in the USFRS XL Project. USFRS may use any

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.
(c) Recordkeeping. USFRS will retain for three years a copy of USFRS
XL waste application forms, and correspondence with each USFRS XL waste
approved customer and generator; records of any spill or leak
notifications it receives; records of its compliance with this subpart
O; and the USFRS XL waste Transportation Tracking Document for each
shipment from a USFRS XL waste generator.

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
[[Page 90]]
cylinder gases at three measurement points within the ranges specified
in Table 2.1-3.

[GRAPHIC] [TIFF OMITTED] TC06NO91.005
Figure 2.1-1 Calibration Drift Determination
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.

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.

2.1.8 Reporting
At a minimum, summarize in tabular form the results of the CD, RA,
response time, and CE test, as appropriate. Include all data sheets,
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.

3.0 SAMPLING AND ANALYTICAL METHODS
Note: The sampling and analytical methods to the BIF manual are
published 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.
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
Stack No. (m) x sec) x ([deg]K) = K
----------------------------------------------------------------------------------------------------------------
1............................ ---------- x ---------- x ---------- = ----------
2............................ ---------- x ---------- x ---------- = ----------
3............................ ---------- x ---------- x ---------- = ----------
----------------------------------------------------------------------------------------------------------------
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.

considered urban.

(B) Based on the TAESH and the urban/rural classification of

------------------------------------------------------------------------
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.
---------------------------------------------------------------------------
Maximum Average Hourly Dispersion Coefficient=----([mu]g/m\3\/g/sec)
(2) For each of the three distance-based generic source numbers
listed in Step 5(E), search down the appropriate generic source number
columns, beginning at the minimum
[[Page 106]]
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 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:
[GRAPHIC] [TIFF OMITTED] TC06NO91.012
[[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).

(D) Compute the TAESH and select generic source numbers (four
sources located in nonflat terrain).
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.
---------------------------------------------------------------------------
Distance Range (km) 0-0.5 0,5-2.5 2.5-5.0

1................................... ... - ... = ..... ... - ... = ......... ... - ... = .....
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;

2................................................................ ........... ............... ...............
3................................................................ ........... ............... ...............
----------------------------------------------------------------------------------------------------------------
(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).

[[Page 113]]
(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.

(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.
[[Page 117]]

information in the spaces provided. Check in the spaces provided whether
the stack designation is complex or noncomplex.

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\

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:
------------------------------------------------------------------------
Concentration
Sample No. of constituent
A (ppm)
------------------------------------------------------------------------
1....................................................... 10
2....................................................... 10
3....................................................... 15
4....................................................... 10
5....................................................... 7
6....................................................... 12
7....................................................... 10
8....................................................... 16
9....................................................... 15
10...................................................... 10
------------------------------------------------------------------------
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.

\1\ Interpolation of thermal input is not allowed. If a BIF fires between two ranges, the APCS temperature under
the higher thermal input must be used.
Example: For a BIF firing 10-100 MMBtu/hr, Mercury is considered very volatile at APCS temperatures above 260 F
and volatile at APCS temperatures of 260 F and below.

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.

(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:

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
as described in Sec. 268.3(c)(1), and is specifically listed in appendix
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.

for which the demonstration will be made;
(2) A waste analysis to describe fully the chemical and physical
characteristics of the subject waste;
(3) A comprehensive characterization of the disposal unit site
including an analysis of background air, soil, and water quality.
(4) A monitoring plan that detects migration at the earliest
practicable time;
[[Page 145]]
(5) Sufficient information to assure the Administrator that the
owner or operator of a land disposal unit receiving restricted waste(s)
will comply with other applicable Federal, State, and local laws.
(b) The demonstration referred to in paragraph (a) of this section
must meet the following criteria:
(1) All waste and environmental sampling, test, and analysis data
must be accurate and reproducible to the extent that state-of-the-art
techniques allow;
(2) All sampling, testing, and estimation techniques for chemical
and physical properties of the waste and all environmental parameters
must have been approved by the Administrator;
(3) Simulation models must be calibrated for the specific waste and
site conditions, and verified for accuracy by comparison with actual
measurements;
(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
where monitoring of the unit is required;
(iii) The location of the monitoring stations;
(iv) The monitoring interval (frequency of monitoring at each
station);
(v) The specific hazardous constituents to be monitored;
(vi) The implementation schedule for the monitoring program;
(vii) The equipment used at the monitoring stations;

(2) Where applicable, the monitoring program described in paragraph
(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
aspects of the monitoring program must be provided to and approved by
the Administrator.
(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.

[[Page 147]]
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:

------------------------------------------------------------------------
(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
268.45. I am aware that there are significant penalties for making a
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.

section of the printed volume and on GPO Access.
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]
