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, 2000), 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.

(ii) You must document in the operating record each time you change
from one mode of operation to the alternate mode and begin complying
with the operating parameter limits for that alternate mode of
operation.
(iii) You must establish rolling averages for the operating
parameter limits anew (i.e., without considering previous recordings)
when you begin complying with the operating limits for the alternate
mode of operation.
(iv) If your in-line kiln raw mill has dual stacks, you may assume
that the dioxin/furan emission levels in the by-pass stack and the
operating parameter limits determined during performance testing of the
by-pass stack when the raw mill is off-line are the same as when the
mill is on-line.
(2) Emissions averaging. You may comply with the mercury,
semivolatile metal, low volatile metal, and hydrochloric acid/chlorine
gas emission standards on a time-weighted average basis under the
following procedures:
(i) Averaging methodology. You must calculate the time-weighted
average emission concentration with the following equation:
Where:
Ctotal=time-weighted average concentration of a regulated
constituent considering both raw mill on time and off time.
Cmill-off=average performance test concentration of regulated
constituent with the raw mill off-line.
Cmill-on=average performance test concentration of regulated
constituent with the raw mill on-line.
Tmill-off=time when kiln gases are not routed through the raw
mill
Tmill-on=time when kiln gases are routed through the raw mill

performance test plan to estimate future raw mill down-time and document
in the performance test plan that estimated emissions and estimated raw
mill down-time will not result in an exceedance of an emission standard
on an annual basis.
(C) You must document in the notification of compliance submitted
under Sec. 63.1207(j) that an emission standard will not be exceeded
based on the documented emissions from the performance test and
predicted raw mill down-time.
(e) Preheater or preheater/precalciner kilns with dual stacks.--(1)
General. You must conduct performance testing on each stack to
demonstrate compliance with the emission standards, and you must
establish operating parameter limits under Sec. 63.1209 for each stack,
except as provided by paragraph (d)(1)(iv) of this section for dioxin/
furan emissions testing and operating parameter limits for the by-pass
stack of in-line raw mills.
(2) Emissions averaging. You may comply with the mercury,
semivolatile metal, low volatile metal, and hydrochloric acid/chlorine
gas emission standards specified in this section on a gas flowrate-
weighted average basis under the following procedures:
(i) Averaging methodology. You must calculate the gas flowrate-
weighted average emission concentration using the following equation:
[GRAPHIC] [TIFF OMITTED] TR30SE99.020
Where

the performance tests and the equation provided by paragraph (e)(1) of
this section; and
(B) You must develop operating parameter limits for bypass stack and
main stack flowrates that ensure the emission concentrations calculated
with the equation in paragraph (e)(1) of this section do not exceed the
emission standards on a 12-hour rolling average basis. You must include
these flowrate limits in the Notification of Compliance.
(iii) Notification. If you elect to document compliance under this
emissions averaging provision, you must:
(A) Notify the Administrator in the initial comprehensive
performance test plan submitted under Sec. 63.1207(e). The performance
test plan must include, at a minimum, information describing the
flowrate limits established under paragraph (e)(2)(ii)(B) of this
section; and
(B) Document in the Notification of Compliance submitted under
Sec. 63.1207(j) the demonstrated gas flowrate-weighted average emissions
that you calculate with the equation provided by paragraph (e)(2) of
this section.

Monitoring and Compliance Provisions
Sec. 63.1206 When and how must you comply with the standards and operating requirements?
(a) Compliance dates--(1) Compliance date for existing sources. You
must comply with the standards of this subpart no later than September
30, 2002 unless the Administrator grants you an extension of time under
Sec. 63.6(i) or Sec. 63.1213, or you comply with the requirements of
paragraph (a)(2) of this section for sources that do not intend to
comply with the emission standards.
(2) Sources that do not intend to comply. Except for those sources
meeting the requirements of Sec. 63.1210(b)(1)(iv), sources:
(i) That signify in their Notification of Intent to Comply (NIC) an
intent not to comply with the requirements of this subpart, must stop
burning hazardous waste on or before October 1, 2001.
(ii) That do not intend to comply with this subpart must include in
their NIC a schedule that includes key dates for the steps to be taken
to stop burning hazardous waste. Key dates include the date for
submittal of RCRA closure
[[Page 21]]
documents required under subpart G, part 264, of this chapter.
(3) New or reconstructed sources. (i) If you commenced construction
or reconstruction of your hazardous waste combustor after April 19,
1996, you must comply with this subpart by the later of September 30,
1999 or the date the source starts operations, except as provided by
paragraph (a)(3)(ii) of this section.
(ii) For a standard in this subpart that is more stringent than the
standard proposed on April 19, 1996, you may achieve compliance no later
than September 30, 2002 if you comply with the standard proposed on
April 19, 1996 after September 30, 1999. This exception does not apply,
however, to new or reconstructed area source hazardous waste combustors
that become major sources after September 30, 1999. As provided by
Sec. 63.6(b)(7), such sources must comply with this subpart at startup.
(b) Compliance with standards--(1) Applicability. The emission
standards and operating requirements set forth in this subpart apply at
all times except:
(i) During startup, shutdown, and malfunction, provided that
hazardous waste is not in the combustion chamber (i.e., the hazardous
waste feed to the combustor has been cutoff for a period of time not
less than the hazardous waste residence time) during those periods of
operation, as provided by paragraph (c)(2)(ii) of this section; and
(ii) When hazardous waste is not in the combustion chamber (i.e.,
the hazardous waste feed to the combustor has been cutoff for a period
of time not less than the hazardous waste residence time), and you have:
(A) Submitted a written, one-time notice to the Administrator
documenting compliance with all applicable requirements and standards
promulgated under authority of the Clean Air Act, including sections 112
and 129; and
(B) Documented in the operating record that you are complying with
such applicable requirements in lieu of the emission standards and
operating requirements of this subpart.
(2) Methods for determining compliance. The Administrator will
determine compliance with the emission standards of this subpart as
provided by Sec. 63.6(f)(2). Conducting performance testing under
operating conditions representative of the extreme range of normal
conditions is consistent with the requirements of
Secs. 63.6(f)(2)(iii)(B) and 63.7(e)(1) to conduct performance testing
under representative operating conditions.
(3) Finding of compliance. The Administrator will make a finding
concerning compliance with the emission standards and other requirements
of this subpart as provided by Sec. 63.6(f)(3).
(4) Extension of compliance with emission standards. The
Administrator may grant an extension of compliance with the emission
standards of this subpart as provided by Secs. 63.6(i) and 63.1213.
(5) Changes in design, operation, or maintenance--(i) Changes that
may adversely affect compliance. If you plan to change (as defined in
paragraph (b)(6)(iii) of this section) the design, operation, or
maintenance practices of the source in a manner that may adversely
affect compliance with any emission standard that is not monitored with
a CEMS:
(A) Notification. You must notify the Administrator at least 60 days
prior to the change, unless you document circumstances that dictate that
such prior notice is not reasonably feasible. The notification must
include:
(1) A description of the changes and which emission standards may be
affected; and
(2) A comprehensive performance test schedule and test plan under
the requirements of Sec. 63.1207(f) that will document compliance with
the affected emission standard(s);
(B) Performance test. You must conduct a comprehensive performance
test under the requirements of Secs. 63.1207(f)(1) and (g)(1) to
document compliance with the affected emission standard(s) and establish
operating parameter limits as required under Sec. 63.1209, and submit to
the Administrator a Notification of Compliance under Secs. 63.1207(j)
and 63.1210(d); and
(C) Restriction on waste burning. (1) Except as provided by
paragraph (b)(5)(i)(C)(2) of this section, after the change and prior to
submitting the notification of compliance, you must not burn hazardous
waste for more than a total of 720 hours and only for purposes
[[Page 22]]
of pretesting or comprehensive performance testing.
(2) You may petition the Administrator to obtain written approval to
burn hazardous waste in the interim prior to submitting a Notification
of Compliance for purposes other than testing or pretesting. You must
specify operating requirements, including limits on operating
parameters, that you determine will ensure compliance with the emission
standards of this subpart based on available information. The
Administrator will review, modify as necessary, and approve if warranted
the interim operating requirements.
(ii) Changes that will not affect compliance. If you determine that
a change will not adversely affect compliance with the emission
standards or operating requirements, you must document the change in the
operating record upon making such change. You must revise as necessary
the performance test plan, Documentation of Compliance, Notification of
Compliance, and start-up, shutdown, and malfunction plan to reflect
these changes.
(iii) Definition of ``change''. For purposes of paragraph (b)(6) of
this section, ``change'' means any change in design, operation, or
maintenance practices that were documented in the comprehensive
performance test plan, Notification of Compliance, or startup, shutdown,
and malfunction plan.
(6) Compliance with the carbon monoxide and hydrocarbon emission
standards. This paragraph applies to sources that elect to comply with
the carbon monoxide and hydrocarbon emissions standards under
Secs. 63.1203 through 63.1205 by documenting continuous compliance with
the carbon monoxide standard using a continuous emissions monitoring
system and documenting compliance with the hydrocarbon standard during
the destruction and removal efficiency (DRE) performance test or its
equivalent.
(i) If a DRE test performed after March 30, 1998 is acceptable as
documentation of compliance with the DRE standard, you may use the
highest hourly rolling average hydrocarbon level achieved during those
DRE test runs to document compliance with the hydrocarbon standard. An
acceptable DRE test is a test that was used to support successful
issuance or reissuance of an operating permit under part 270 of this
chapter.
(ii) If during this acceptable DRE test you did not obtain
hydrocarbon emissions data sufficient to document compliance with the
hydrocarbon standard, you must either:
(A) Perform, as part of the performance test, an ``equivalent DRE
test'' to document compliance with the hydrocarbon standard. An
equivalent DRE test is comprised of a minimum of three runs each with a
minimum duration of one hour during which you operate the combustor as
close as reasonably possible to the operating parameter limits that you
established based on the initial DRE test. You must use the highest
hourly rolling average hydrocarbon emission level achieved during the
equivalent DRE test to document compliance with the hydrocarbon
standard; or (B) Perform a DRE test as part of the performance test.
(7) Compliance with the DRE standard. (i) Except as provided in
paragraphs (b)(7)(ii) and (b)(7)(iii) of this section:
(A) You must document compliance with the Destruction and Removal
Efficiency (DRE) standard under Secs. 63.1203 through 63.1205 only once
provided that you do not modify the source after the DRE test in a
manner that could affect the ability of the source to achieve the DRE
standard; and
(B) You may use DRE testing performed after March 30, 1998 for
purposes of issuance or reissuance of a RCRA permit under part 270 of
this chapter to document conformance with the DRE standard if you have
not modified the design or operation of the source since the DRE test in
a manner that could affect the ability of the source to achieve the DRE
standard.
(ii) For sources that feed hazardous waste at a location in the
combustion system other than the normal flame zone:
(A) You must demonstrate compliance with the DRE standard during
each comprehensive performance test; and
(B) You may use DRE testing performed after March 30, 1998 for
purposes of issuance or reissuance of a RCRA permit under part 270 of
this chapter to document conformance with
[[Page 23]]
the DRE standard in lieu of DRE testing during the initial comprehensive
performance test if you have not modified the design or operation of the
source since the DRE test in a manner that could affect the ability of
the source to achieve the DRE standard.
(iii) For sources that do not use DRE testing performed prior to the
compliance date to document conformance with the DRE standard, you must
perform DRE testing during the initial comprehensive performance test.
(8) Applicability of particulate matter and opacity standards during
particulate matter CEMS correlation tests. (i) Any particulate matter
and opacity standards of parts 60, 61, 63, 264, 265, and 266 of this
chapter (i.e., any title 40 particulate or opacity standards) applicable
to a hazardous waste combustor do not apply while you conduct
particulate matter continuous emissions monitoring system (CEMS)
correlation tests (i.e., correlation with manual stack methods) under
the conditions of paragraphs (b)(8)(iii) through (vii) of this section.
(ii) Any permit or other emissions or operating parameter limits or
conditions, including any limitation on workplace practices, that are
applicable to hazardous waste combustors to ensure compliance with any
particulate matter and opacity standards of parts 60, 61, 63, 264, 265,
and 266 of this chapter (i.e., any title 40 particulate or opacity
standards) do not apply while you conduct particulate matter CEMS
correlation tests under the conditions of paragraphs (b)(8)(iii) through
(vii) of this section.
(iii) For the provisions of this section to apply, you must:
(A) Develop a particulate matter CEMS correlation test plan that
includes the following information. This test plan may be included as
part of the comprehensive performance test plan required under
Secs. 63.1207(e) and (f):
(1) Number of test conditions and number of runs for each test
condition;
(2) Target particulate matter emission level for each test
condition;
(3) How you plan to modify operations to attain the desired
particulate matter emission levels; and
(4) Anticipated normal particulate matter emission levels; and
(B) Submit the test plan to the Administrator for approval at least
90 calendar days before the correlation test is scheduled to be
conducted.
(iv) The Administrator will review and approve/disapprove the
correlation test plan under the procedures for review and approval of
the site-specific test plan provided by Sec. 63.7(c)(3)(i) and (iii). If
the Administrator fails to approve or disapprove the correlation test
plan within the time period specified by Sec. 63.7(c)(3)(i), the plan is
considered approved, unless the Administrator has requested additional
information.
(v) The particulate matter and opacity standards and associated
operating limits and conditions will not be waived for more than 96
hours, in the aggregate, for a correlation test, including all runs of
all test conditions.
(vi) The stack sampling team must be on-site and prepared to perform
correlation testing no later than 24 hours after you modify operations
to attain the desired particulate matter emissions concentrations,
unless you document in the correlation test plan that a longer period of
conditioning is appropriate.
(vii) You must return to operating conditions indicative of
compliance with the applicable particulate matter and opacity standards
as soon as possible after correlation testing is completed.

under the operating requirements specified in the Documentation of
Compliance under Sec. 63.1211(d) or the Notification of Compliance under
Secs. 63.1207(j) and 63.1210(d), except:
[[Page 27]]
(A) During performance tests under approved test plans according to
Sec. 63.1207(e), (f), and (g), and
(B) Under the conditions of paragraph (b)(1)(i) or (ii) of this
section;
(ii) The Documentation of Compliance and the Notification of
Compliance must contain operating requirements including, but not
limited to, the operating requirements in this section and Sec. 63.1209
(iii) Failure to comply with the operating requirements is failure
to ensure compliance with the emission standards of this subpart;
(iv) Operating requirements in the Notification of Compliance are
applicable requirements for purposes of parts 70 and 71 of this chapter;
(v) The operating requirements specified in the Notification of
Compliance will be incorporated in the title V permit.
(2) Startup, shutdown, and malfunction plan. (i) Except as provided
by paragraph (c)(2)(ii) of this section, you are subject to the startup,
shutdown, and malfunction plan requirements of Sec. 63.6(e)(3).
(ii) Even if you follow the startup and shutdown procedures and the
corrective measures upon a malfunction that are prescribed in the
startup, shutdown, and malfunction plan, the emission standards and
operating requirements of this subpart apply if hazardous waste is in
the combustion chamber (i.e., if you are feeding hazardous waste or if
startup, shutdown, or a malfunction occurs before the hazardous waste
residence time has transpired after hazardous waste cutoff).
(iii) You must identify in the plan a projected oxygen correction
factor based on normal operations to use during periods of startup and
shutdown.
(iv) You must record the plan in the operating record.
(3) Automatic waste feed cutoff (AWFCO)--(i) General. Upon the
compliance date, you must operate the hazardous waste combustor with a
functioning system that immediately and automatically cuts off the
hazardous waste feed, except as provided by paragraph (c)(3)(viii) of
this section:
(A) When any of the following are exceeded: Operating parameter
limits specified under Sec. 63.1209; an emission standard monitored by a
CEMS; and the allowable combustion chamber pressure;
(B) When the span value of any CMS detector, except a CEMS, is met
or exceeded;
(C) Upon malfunction of a CMS monitoring an operating parameter
limit specified under Sec. 63.1209 or an emission level; or
(D) When any component of the automatic waste feed cutoff system
fails.
(ii) Ducting of combustion gases. During an AWFCO, you must continue
to duct combustion gasses to the air pollution control system while
hazardous waste remains in the combustion chamber (i.e., if the
hazardous waste residence time has not transpired since the hazardous
waste feed cutoff system was activated).
(iii) Restarting waste feed. You must continue to monitor during the
cutoff the operating parameters for which limits are established under
Sec. 63.1209 and the emissions required under that section to be
monitored by a CEMS, and you must not restart the hazardous waste feed
until the operating parameters and emission levels are within the
specified limits.
(iv) Failure of the AWFCO system. If the AWFCO system fails to
automatically and immediately cutoff the flow of hazardous waste upon
exceedance of parameter required to be interlocked with the AWFCO system
under paragraph (c)(3)(i) of this section, you have failed to comply
with the AWFCO requirements of paragraph (c)(3) of this section.
(v) Corrective measures. If, after any AWFCO, there is an exceedance
of an emission standard or operating requirement, irrespective of
whether the exceedance occurred while hazardous waste remained in the
combustion chamber (i.e., whether the hazardous waste residence time has
transpired since the hazardous waste feed cutoff system was activated),
you must investigate the cause of the AWFCO, take appropriate corrective
measures to minimize future AWFCOs, and record the findings and
corrective measures in the operating record.
(vi) Excessive exceedance reporting. (A) For each set of 10
exceedances of an
[[Page 28]]
emission standard or operating requirement while hazardous waste remains
in the combustion chamber (i.e., when the hazardous waste residence time
has not transpired since the hazardous waste feed was cutoff) during a
60-day block period, you must submit to the Administrator a written
report within 5 calendar days of the 10th exceedance documenting the
exceedances and results of the investigation and corrective measures
taken.
(B) On a case-by-case basis, the Administrator may require excessive
exceedance reporting when fewer than 10 exceedances occur during a 60-
day block period.
(vii) Testing. The AWFCO system and associated alarms must be tested
at least weekly to verify operability, unless you document in the
operating record that weekly inspections will unduly restrict or upset
operations and that less frequent inspection will be adequate. At a
minimum, you must conduct operability testing at least monthly. You must
document and record in the operating record AWFCO operability test
procedures and results.
(viii) Ramping down waste feed. (A) You may ramp down the waste
feedrate of pumpable hazardous waste over a period not to exceed one
minute, except as provided by paragraph (c)(3)(viii)(B) of this section.
If you elect to ramp down the waste feed, you must document ramp down
procedures in the operating and maintenance plan. The procedures must
specify that the ramp down begins immediately upon initiation of
automatic waste feed cutoff and the procedures must prescribe a bona
fide ramping down. If an emission standard or operating limit is
exceeded during the ramp down, you have failed to comply with the
emission standards or operating requirements of this subpart.
(B) If the automatic waste feed cutoff is triggered by an exceedance
of any of the following operating limits, you may not ramp down the
waste feed cutoff: Minimum combustion chamber temperature, maximum
hazardous waste feedrate, or any hazardous waste firing system operating
limits that may be established for your combustor.
(4) ESV openings--(i) Failure to meet standards. If an emergency
safety vent (ESV) opens when hazardous waste remains in the combustion
chamber (i.e., when the hazardous waste residence time has not
transpired since the hazardous waste feed cutoff system was activated)
such that combustion gases are not treated as during the most recent
comprehensive performance test (e.g., if the combustion gas by-passes
any emission control device that was operating during the performance
test), it is evidence of your failure to comply with the emission
standards of this subpart.
(ii) ESV operating plan. (A) You must develop an ESV operating plan,
comply with the operating plan, and keep the plan in the operating
record.
(B) The ESV operating plan must provide detailed procedures for
rapidly stopping the waste feed, shutting down the combustor, and
maintaining temperature and negative pressure in the combustion chamber
during the hazardous waste residence time, if feasible. The plan must
include calculations and information and data documenting the
effectiveness of the plan's procedures for ensuring that combustion
chamber temperature and negative pressure are maintained as is
reasonably feasible.
(iii) Corrective measures. After any ESV opening that results in a
failure to meet the emission standards as defined in paragraph (c)(4)(i)
of this section, you must investigate the cause of the ESV opening, take
appropriate corrective measures to minimize such future ESV openings,
and record the findings and corrective measures in the operating record.
(iv) Reporting requirement. You must submit to the Administrator a
written report within 5 days of an ESV opening that results in failure
to meet the emission standards of this subpart (as defined in paragraph
(c)(4)(i) of this section) documenting the result of the investigation
and corrective measures taken.
(5) Combustion system leaks. (i) Combustion system leaks of
hazardous air pollutants must be controlled by:
(A) Keeping the combustion zone sealed to prevent combustion system
leaks; or
[[Page 29]]
(B) Maintaining the maximum combustion zone pressure lower than
ambient pressure using an instantaneous monitor; or
(C) Upon prior written approval of the Administrator, an alternative
means of control to provide control of combustion system leaks
equivalent to maintenance of combustion zone pressure lower than ambient
pressure; and
(ii) You must specify in the operating record the method used for
control of combustion system leaks.
(6) Operator training and certification. (i) You must establish a
training and certification program for each person who has
responsibilities affecting operations that may affect emissions of
hazardous air pollutants from the source. Such persons include, but are
not limited to, chief facility operators, control room operators,
continuous monitoring system operators, persons that sample and analyze
feedstreams, persons that manage and charge feedstreams to the
combustor, persons that operate emission control devices, ash and waste
handlers, and maintenance personnel.
(ii) You must ensure that the source is operated and maintained at
all times by persons who are trained and certified to perform these and
any other duties that may affect emissions of hazardous air pollutants.
(iii) For hazardous waste incinerators, the training and
certification program must conform to a state-approved training and
certification program or, if there is no such state program, to the
American Society of Mechanical Engineers Standard Number QHO-1-1994.
(iv) For hazardous waste burning cement and lightweight aggregate
kilns, the training and certification program must be approved by the
state or the Administrator, and must be complete and reliable and
conform to principles of good operator and operating practices
(including training and certification).
(v) You must record the operator training and certification program
in the operating record.
(7) Operation and maintenance plan--(i) General. (A) You must
prepare and at all times operate according to an operation and
maintenance plan that describes in detail procedures for operation,
inspection, maintenance, and corrective measures for all components of
the combustor, including associated pollution control equipment, that
could affect emissions of regulated hazardous air pollutants.
(B) The plan must prescribe how you will operate and maintain the
combustor in a manner consistent with good air pollution control
practices for minimizing emissions at least to the levels achieved
during the comprehensive performance test.
(C) This plan ensures compliance with the operation and maintenance
requirements of Sec. 63.6(e) and minimizes emissions of pollutants,
automatic waste feed cutoffs, and malfunctions.
(D) You must record the plan in the operating record.
(ii) Requirements for baghouses at lightweight aggregate kilns and
incinerators. If you own or operate a hazardous waste incinerator or
hazardous waste burning lightweight aggregate kiln equipped with a

performance testing) or with the notification of performance test
required under paragraph (e) of this section.
(d) Frequency of testing. You must conduct testing periodically as
prescribed in paragraphs (d)(1) through (3) of this section. The date of
commencement of the initial comprehensive performance test is the basis
for establishing the deadline to commence the initial confirmatory
performance test and the next comprehensive performance test. You may
conduct performance testing at any time prior to the required date. The
deadline for commencing subsequent confirmatory and comprehensive
performance testing is based on the date of commencement of the previous
comprehensive performance test. Unless the Administrator grants a time
extension under paragraph (i) of this section, you must conduct testing
as follows:
(1) Comprehensive performance testing. You must commence testing no
later than 61 months after the date of commencing the previous
comprehensive performance test. If you submit data in lieu of the
initial performance test, you must commence the subsequent comprehensive
performance test within 61 months of the date six months after the
compliance date.
(2) Confirmatory performance testing. You must commence confirmatory
performance testing no later than 31 months after the date of commencing
the previous comprehensive performance test. If you submit data in lieu
of the initial performance test, you must commence the initial
confirmatory performance test within 31 months of the date six months
after the compliance date. To ensure that the confirmatory test is
conducted approximately midway between comprehensive performance tests,
the Administrator will
[[Page 32]]
not approve a test plan that schedules testing within 18 months of
commencing the previous comprehensive performance test.
(3) Duration of testing. You must complete performance testing
within 60 days after the date of commencement, unless the Administrator
determines that a time extension is warranted based on your
documentation in writing of factors beyond your control that prevent you
from meeting the 60-day deadline.
(e) Notification of performance test and CMS performance evaluation,

levels, as specified in paragraph (g)(2)(ii) of this section, and an
explanation of how these normal levels were determined;
(iii) A description of your normal chlorine operating levels, as
specified in paragraph (g)(2)(iii) of this section, and an explanation
of how these normal levels were determined;
(iv) If you use carbon injection or a carbon bed, a description of
your normal cleaning cycle of the particulate matter control device, as
specified in paragraph (g)(2)(iv) of this section, and an explanation of
how these normal levels were determined;
(v) A detailed description of sampling and monitoring procedures
including sampling and monitoring locations in the system, the equipment
to be used, sampling and monitoring frequency, and planned analytical
procedures for sample analysis;
(vi) A detailed test schedule for each hazardous waste for which the
performance test is planned, including date(s), duration, quantity of
hazardous waste to be burned, and other relevant factors;
[[Page 34]]
(vii) A detailed test protocol, including, for each hazardous waste
identified, the ranges of hazardous waste feedrate for each feed system,
and, as appropriate, the feedrates of other fuels and feedstocks, and
any other relevant parameters that may affect the ability of the
hazardous waste combustor to meet the dioxin/furan emission standard;
(viii) A description of, and planned operating conditions for, any
emission control equipment that will be used;
(ix) Procedures for rapidly stopping the hazardous waste feed and
controlling emissions in the event of an equipment malfunction; and
(x) Such other information as the Administrator reasonably finds
necessary to determine whether to approve the confirmatory test plan.
(g) Operating conditions during testing. You must comply with the
provisions of Sec. 63.7(e). Conducting performance testing under
operating conditions representative of the extreme range of normal
conditions is consistent with the requirement of Sec. 63.7(e)(1) to
conduct performance testing under representative operating conditions.
(1) Comprehensive performance testing--(i) Operations during
testing. For the following parameters, you must operate the combustor
during the performance test under normal conditions (or conditions that
will result in higher than normal emissions):
(A) Chlorine feedrate. You must feed normal (or higher) levels of
chlorine during the dioxin/furan performance test;
(B) Ash feedrate. For hazardous waste incinerators, you must conduct
the following tests when feeding normal (or higher) levels of ash: The
semivolatile metal and low volatile metal performance tests; and the
dioxin/furan and mercury performance tests if activated carbon injection
or a carbon bed is used; and
(C) Cleaning cycle of the particulate matter control device. You
must conduct the following tests when the particulate matter control
device undergoes its normal (or more frequent) cleaning cycle: The
particulate matter, semivolatile metal, and low volatile metal
performance tests; and the dioxin/furan and mercury performance tests if
activated carbon injection or a carbon bed is used.
(ii) Modes of operation. Given that you must establish limits for
the applicable operating parameters specified in Sec. 63.1209 based on
operations during the comprehensive performance test, you may conduct
testing under two or more operating modes to provide operating
flexibility.
(iii) Steady-state conditions. (A) Prior to obtaining performance
test data, you must operate under performance test conditions until you
reach steady-state operations with respect to emissions of pollutants
you must measure during the performance test and operating parameters
under Sec. 63.1209 for which you must establish limits. During system
conditioning, you must ensure that each operating parameter for which
you must establish a limit is held at the level planned for the
performance test. You must include documentation in the performance test
plan under paragraph (f) of this section justifying the duration of
system conditioning.
(B) If you own or operate a hazardous waste cement kiln that
recycles collected particulate matter (i.e., cement kiln dust) into the
kiln, you must sample and analyze the recycled particulate matter prior
to obtaining performance test data for levels of selected metals that
must be measured during performance testing to document that the system
has reached steady-state conditions (i.e., that metals levels have
stabilized). You must document the rationale for selecting metals that
are indicative of system equilibrium and include the information in the
performance test plan under paragraph (f) of this section. To determine
system equilibrium, you must sample and analyze the recycled particulate
matter hourly for each selected metal, unless you submit in the
performance test plan a justification for reduced sampling and analysis
and the Administrator approves in writing a reduced sampling and
analysis frequency.
(2) Confirmatory performance testing. You must conduct confirmatory
performance testing for dioxin/furan under normal operating conditions
for the following parameters:
[[Page 35]]
(i) Carbon monoxide (or hydrocarbon) CEMS emission levels must be
within the range of the average value to the maximum value allowed. The
average value is defined as the sum of the hourly rolling average values
recorded (each minute) over the previous 12 months divided by the number
of rolling averages recorded during that time;
(ii) Each operating limit (specified in Sec. 63.1209) established to
maintain compliance with the dioxin/furan emission standard must be held
within the range of the average value over the previous 12 months and
the maximum or minimum, as appropriate, that is allowed. The average
value is defined as the sum of the rolling average values recorded over
the previous 12 months divided by the number of rolling averages
recorded during that time. The average value must not include
calibration data, malfunction data, and data obtained when not burning
hazardous waste;
(iii) You must feed chlorine at normal feedrates or greater; and
(iv) If the combustor is equipped with carbon injection or carbon bed,
normal cleaning cycle of the particulate matter control device.
(h) Operating conditions during subsequent testing. (1) Current
operating parameter limits established under Sec. 63.1209 are waived
during subsequent comprehensive performance testing under an approved
test plan.
(2) Current operating parameter limits are also waived during
pretesting prescribed in the approved test plan prior to comprehensive
performance testing for an aggregate time not to exceed 720 hours of
operation. Pretesting means:
(i) Operations when stack emissions testing for dioxin/furan,
mercury, semivolatile metals, low volatile metals, particulate matter,
or hydrochloric acid/chlorine gas is being performed; and
(ii) Operations to reach steady-state operating conditions prior to
stack emissions testing under paragraph (g)(1)(iii) of this section.
(i) Time extension for subsequent performance tests. After the
initial comprehensive performance test, you may request up to a one-year
time extension for conducting a comprehensive or confirmatory
performance test to consolidate performance testing with other state or
federally required emission testing, or for other reasons deemed
acceptable by the Administrator. If the Administrator grants a time
extension for a comprehensive performance test, the deadlines for
commencing the next comprehensive and confirmatory tests are based on
the date that the subject comprehensive performance test commences.
(1) You must submit in writing to the Administrator any request
under this paragraph for a time extension for conducting a performance
test.
(2) You must include in the request for an extension for conducting
a performance test the following:
(i) A description of the reasons for requesting the time extension;
(ii) The date by which you will commence performance testing.
(3) The Administrator will notify you in writing of approval or
intention to deny approval of your request for an extension for
conducting a performance test within 30 calendar days after receipt of
sufficient information to evaluate your request. The 30-day approval or
denial period will begin after you have been notified in writing that
your application is complete. The Administrator will notify you in
writing whether the application contains sufficient information to make
a determination within 30 calendar days after receipt of the original
application and within 30 calendar days after receipt of any
supplementary information that you submit.
(4) When notifying you that your application is not complete, the
Administrator will specify the information needed to complete the
application. The Administrator will also provide notice of opportunity
for you to present, in writing, within 30 calendar days after
notification of the incomplete application, additional information or
arguments to the Administrator to enable further action on the
application.
(5) Before denying any request for an extension for performance
testing, the Administrator will notify you in writing of the
Administrator's intention to issue the denial, together with:
[[Page 36]]
(i) Notice of the information and findings on which the intended
denial is based; and
(ii) Notice of opportunity for you to present in writing, within 15
calendar days after notification of the intended denial, additional
information or arguments to the Administrator before further action on
the request.
(6) The Administrator's final determination to deny any request for
an extension will be in writing and will set forth specific grounds upon
which the denial is based. The final determination will be made within
30 calendar days after the presentation of additional information or
argument (if the application is complete), or within 30 calendar days
after the final date specified for the presentation if no presentation
is made.
(j) Notification of compliance--(1) Comprehensive performance test.
(i) Except as provided by paragraph (j)(4) of this section, within 90
days of completion of a comprehensive performance test, you must
postmark a Notification of Compliance documenting compliance or
noncompliance with the emission standards and continuous monitoring
system requirements, and identifying operating parameter limits under
Sec. 3.1209.
(ii) Upon postmark of the Notification of Compliance, you must
comply with all operating requirements specified in the Notification of
Compliance in lieu of the limits specified in the Documentation of
Compliance required under Sec. 63.1211(d).
(2) Confirmatory performance test. Except as provided by paragraph
(j)(4) of this section, within 90 days of completion of a confirmatory
performance test, you must postmark a Notification of Compliance
documenting compliance or noncompliance with the applicable dioxin/furan
emission standard.
(3) See Secs. 63.7(g), 63.9(h), and 63.1210(d) for additional
requirements pertaining to the Notification of Compliance (e.g., you
must include results of performance tests in the Notification of
Compliance).
(4) Time extension. You may submit a written request to the
Administrator for a time extension documenting that, for reasons beyond
your control, you may not be able to meet the 90-day deadline for
submitting the Notification of Compliance after completion of testing.
The Administrator will determine whether a time extension is warranted.
(k) Failure to submit a timely notification of compliance. (1) If
you fail to postmark a Notification of Compliance by the specified date,
you must cease hazardous waste burning immediately.
(2) Prior to submitting a revised Notification of Compliance as
provided by paragraph (k)(3) of this section, you may burn hazardous
waste only for the purpose of pretesting or comprehensive performance
testing and only for a maximum of 720 hours (renewable at the discretion
of the Administrator).
(3) You must submit to the Administrator a Notification of
Compliance subsequent to a new comprehensive performance test before
resuming hazardous waste burning.
(l) Failure of performance test--(1) Comprehensive performance test.
(i) If you determine (based on CEM recordings, results of analyses of
stack samples, or results of CMS performance evaluations) that you have
exceeded any emission standard during a comprehensive performance test
for a mode of operation, you must cease hazardous waste burning
immediately under that mode of operation. You must make this
determination within 90 days following completion of the performance
test.
(ii) If you have failed to demonstrate compliance with the emission
standards for any mode of operation:
(A) Prior to submitting a revised Notification of Compliance as
provided by paragraph (l)(1)(ii)(C) of this section, you may burn
hazardous waste only for the purpose of pretesting or comprehensive
performance testing under revised operating conditions, and only for a
maximum of 720 hours (renewable at the discretion of the Administrator),
except as provided by paragraph (l)(3) of this section;
(B) You must conduct a comprehensive performance test under revised
operating conditions following the requirements for performance testing
of this section; and
(C) You must submit to the Administrator a Notification of
Compliance subsequent to the new comprehensive performance test.
[[Page 37]]
(2) Confirmatory performance test. If you determine (based on CEM
recordings, results of analyses of stack samples, or results of CMS
performance evaluations) that you have failed the dioxin/furan emission
standard during a confirmatory performance test, you must cease burning
hazardous waste immediately. You must make this determination within 90
days following completion of the performance test. To burn hazardous
waste in the future:
(i) You must submit to the Administrator for review and approval a
test plan to conduct a comprehensive performance test to identify
revised limits on the applicable dioxin/furan operating parameters
specified in Sec. 63.1209(k);
(ii) You must submit to the Administrator a Notification of
Compliance with the dioxin/furan emission standard under the provisions
of paragraphs (j) and (k) of this section and this paragraph (l). You
must include in the Notification of Compliance the revised limits on the
applicable dioxin/furan operating parameters specified in
Sec. 63.1209(k); and
(iii) Until the Notification of Compliance is submitted, you must
not burn hazardous waste except for purposes of pretesting or
confirmatory performance testing, and for a maximum of 720 hours
(renewable at the discretion of the Administrator), except as provided
by paragraph (l)(3) of this section.
(3) You may petition the Administrator to obtain written approval to
burn hazardous waste in the interim prior to submitting a Notification
of Compliance for purposes other than testing or pretesting. You must
specify operating requirements, including limits on operating
parameters, that you determine will ensure compliance with the emission
standards of this subpart based on available information including data
from the failed performance test. The Administrator will review, modify
as necessary, and approve if warranted the interim operating
requirements. An approval of interim operating requirements will include
a schedule for submitting a Notification of Compliance.
(m) Waiver of performance test. (1) The waiver provision of this
paragraph applies in addition to the provisions of Sec. 63.7(h).
(2) You are not required to conduct performance tests to document
compliance with the mercury, semivolatile metal, low volatile metal or
hydrochloric acid/chlorine gas emission standards under the conditions
specified below. You are deemed to be in compliance with an emission
standard if the twelve-hour rolling average maximum theoretical emission
concentration (MTEC) determined as specified below does not exceed the
emission standard:
(i) Determine the feedrate of mercury, semivolatile metals, low
volatile metals, or total chlorine and chloride from all feedstreams;
(ii) Determine the stack gas flowrate; and
(iii) Calculate a MTEC for each standard assuming all mercury,
semivolatile metals, low volatile metals, or total chlorine (organic and
inorganic) from all feedstreams is emitted;
(3) To document compliance with this provision, you must:
(i) Monitor and record the feedrate of mercury, semivolatile metals,
low volatile metals, and total chlorine and chloride from all
feedstreams according to Sec. 63.1209(c);
(ii) Monitor with a CMS and record in the operating record the gas
flowrate (either directly or by monitoring a surrogate parameter that
you have correlated to gas flowrate);
(iii) Continuously calculate and record in the operating record the
MTEC under the procedures of paragraph (m)(2) of this section; and
(iv) Interlock the MTEC calculated in paragraph (m)(2)(iii) of this
section to the AWFCO system to stop hazardous waste burning when the
MTEC exceeds the emission standard.
(4) In lieu of the requirement in paragraphs (m)(3)(iii) and (iv) of
this section, you may:
(i) Identify in the notification of compliance a minimum gas
flowrate limit and a maximum feedrate limit of mercury, semivolatile
metals, low volatile metals, and/or total chlorine and chloride from all
feedstreams that ensures the MTEC as calculated in paragraph (m)(2)(iii)
of this section is
[[Page 38]]
below the applicable emission standard; and
(ii) Interlock the minimum gas flowrate limit and maximum feedrate
limit in paragraph (m)(3)(iv) of this section to the AWFCO system to
stop hazardous waste burning when the gas flowrate or mercury,
semivolatile metals, low volatile metals, and/or total chlorine and
chloride feedrate exceeds the limit in paragraph (m)(4)(i) of this
section.
(5) When you determine the feedrate of mercury, semivolatile metals,
low volatile metals, or total chlorine and chloride for purposes of this
provision, except as provided by paragraph (m)(6) of this section, you
must assume that the analyte is present at the full detection limit when
the feedstream analysis determines that the analyte is not detected in
the feedstream.
(6) Owners and operators of hazardous waste burning cement kilns and
lightweight aggregate kilns may assume that mercury is present in raw
material at half the detection limit when the raw material feedstream
analysis determines that mercury is not detected.
(7) You must state in the site-specific test plan that you submit
for review and approval under paragraph (e) of this section that you
intend to comply with the provisions of this paragraph. You must include
in the test plan documentation that any surrogate that is proposed for
gas flowrate adequately correlates with the gas flowrate.
(n) Feedrate limits for nondetectable constituents. (1) You must
establish separate semivolatile metal, low volatile metal, mercury, and
total chlorine (organic and inorganic), and/or ash feedrate limits for
each feedstream for which the comprehensive performance test feedstream
analysis determines that these constituents are not present at
detectable levels.
(2) You must define the feedrate limits established under paragraph
(n)(1) of this section as nondetect at the full detection limit achieved
during the performance test.
(3) You will not be deemed to be in violation of the feedrate limit
established in paragraph (n)(2) of this section when detectable levels
of the constituent are measured, whether at levels above or below the
full detection limit achieved during the performance test, provided
that:
(i) Your total feedrate for that constituent, including the
detectable levels in the feedstream which is limited to nondetect
levels, is below your feedrate limit for that constituent; or
(ii) Except for ash, your maximum theoretical emission concentration
(MTEC) for the constituent (i.e., semivolatile metal, low volatile
metal, mercury, and/or hydrochloric acid/chlorine gas) calculated
according to paragraph (m) of this section, and considering the
contribution from all feedstreams including the detectable levels in the
feedstream which is limited to nondetect levels, is below the emission
standard in Secs. 63.1203, 63.1204, and 63.1205.

(B) Compliance is based on six-minute block average.
(iii) You must install, calibrate, maintain, and operate a
particulate matter CEMS to demonstrate and monitor compliance with the
particulate matter standards under this subpart. However, compliance
with the requirements in their section to install, calibrate, maintain
and operate the PM CEMS is not required until such time
[[Page 40]]
that the Agency promulgates all performance specifications and
operational requirements applicable to PM CEMS.
(iv) If you operate a cement kiln subject to the provisions of this
subpart and use a fabric filter with multiple stacks or an electrostatic
precipitator with multiple stacks, you may, in lieu of installing the
COMS required by paragraph (a)(1)(ii) of this section, comply with the
opacity standard in accordance with the procedures of Method 9 to part
60 of this chapter:
(A) You must conduct the Method 9 test while the affected source is
operating at the highest load or capacity level reasonably expected to
occur within the day;
(B) The duration of the Method 9 test shall be at least 30 minutes
each day;
(C) You must use the Method 9 procedures to monitor and record the
average opacity for each six-minute block period during the test; and
(D) To remain in compliance, all six-minute block averages must not

(v) If you operate a cement kiln subject to the provisions of this
subpart and use a particulate matter control device that exhausts
through a monovent, or if the use of a COMS in accordance with the
installation specification of Performance Specification 1 (PS-1) of
appendix B to part 60 of this chapter is not feasible, you may, in lieu
of installing the COMS required by paragraph (a)(1)(ii) of this section,
comply with the opacity standard in accordance with the procedures of
Method 9 to part 60 of this chapter:
(A) You must conduct the Method 9 test while the affected source is
operating at the highest load or capacity level reasonably expected to
occur within the day;
(B) The duration of the Method 9 test shall be at least 30 minutes
each day;
(C) You must use the Method 9 procedures to monitor and record the
average opacity for each six-minute block period during the test; and
(D) To remain in compliance, all six-minute block averages must not
exceed the opacity standard under Secs. 63.1204(a)(7) and (b)(7).
(2) Performance specifications. You must install, calibrate,
maintain, and continuously operate the CEMS and COMS in compliance with
the quality assurance procedures provided in the appendix to this
subpart and Performance Specifications 1 (opacity), 4B (carbon monoxide
and oxygen), and 8A (hydrocarbons) in appendix B, part 60 of this
chapter.
(3) Carbon monoxide readings exceeding the span. (i) Except as
provided by paragraph (a)(3)(ii) of this section, if a carbon monoxide
CEMS detects a response that results in a one-minute average at or above
the 3,000 ppmv span level required by Performance Specification 4B in
appendix B, part 60 of this chapter, the one-minute average must be
recorded as 10,000 ppmv. The one-minute 10,000 ppmv value must be used
for calculating the hourly rolling average carbon monoxide level.
(ii) Carbon monoxide CEMS that use a span value of 10,000 ppmv when
one-minute carbon monoxide levels are equal to or exceed 3,000 ppmv are
not subject to paragraph (a)(3)(i) of this section. Carbon monoxide CEMS
that use a span value of 10,000 are subject to the same CEMS performance
and equipment specifications when operating in the range of 3,000 ppmv
to 10,000 ppmv that are provided by Performance Specification 4B for
other carbon monoxide CEMS, except:
(A) Calibration drift must be less than 300 ppmv; and
(B) Calibration error must be less than 500 ppmv.
(4) Hydrocarbon readings exceeding the span. (i) Except as provided
by paragraph (a)(4)(ii) of this section, if a hydrocarbon CEMS detects a
response that results in a one-minute average at or above the 100 ppmv
span level required by Performance Specification 8A in appendix B, part
60 of this chapter, the one-minute average must be recorded as 500 ppmv.
The one-minute 500 ppmv value must be used for calculating the hourly
rolling average HC level.
(ii) Hydrocarbon CEMS that use a span value of 500 ppmv when one-
minute hydrocarbon levels are equal to or exceed 100 ppmv are not
subject to paragraph (a)(4)(i) of this section. Hydrocarbon CEMS that
use a span value
[[Page 41]]
of 500 ppmv are subject to the same CEMS performance and equipment
specifications when operating in the range of 100 ppmv to 500 ppmv that
are provided by Performance Specification 8A for other hydrocarbon CEMS,
except:
(A) The zero and high-level calibration gas must have a hydrocarbon
level of between 0 and 100 ppmv, and between 250 and 450 ppmv,
respectively;
(B) The strip chart recorder, computer, or digital recorder must be
capable of recording all readings within the CEM measurement range and
must have a resolution of 2.5 ppmv;
(C) The CEMS calibration must not differ by more than 15
ppmv after each 24-hour period of the seven day test at both zero and
high levels;
(D) The calibration error must be no greater than 25 ppmv; and
(E) The zero level, mid-level, and high level calibration gas used
to determine calibration error must have a hydrocarbon level of 0-200
ppmv, 150-200 ppmv, and 350-400 ppmv, respectively.
(5) Petitions to use CEMS for other standards. You may petition the
Administrator to use CEMS for compliance monitoring for particulate
matter, mercury, semivolatile metals, low volatile metals, and
hydrochloric acid/chlorine gas under Sec. 63.8(f) in lieu of compliance
with the corresponding operating parameter limits under this section.
(6) Calculation of rolling averages--(i) Calculation of rolling
averages initially. The carbon monoxide and hydrocarbon CEMS must begin
recording one-minute average values by 12:01 am and hourly rolling
average values by 1:01 am, when 60 one-minute values will be available
for calculating the initial hourly rolling average.
(ii) Calculation of rolling averages upon intermittent operations.
You must ignore periods of time when one-minute values are not available
for calculating the hourly rolling average. When one-minute values
become available again, the first one-minute value is added to the
previous 59 values to calculate the hourly rolling average.
(iii) Calculation of rolling averages when the hazardous waste feed
is cutoff. (A) Except as provided by paragraph (a)(6)(iii)(B) of this
section, you must continue to monitoring carbon monoxide and hydrocarbon
when the hazardous waste feed is cutoff if the source is operating. You
must not resume feeding hazardous waste if the emission levels exceed
the standard.
(B) You are not subject to the CEMS requirements of this subpart
during periods of time you meet the requirements of
Sec. 63.1206(b)(1)(ii) (compliance with emissions standards for
nonhazardous waste burning sources when you are not burning hazardous
waste).
(7) Operating parameter limits for hydrocarbons. If you elect to
comply with the carbon monoxide and hydrocarbon emission standards by
continuously monitoring carbon monoxide with a CEMS, you must
demonstrate that hydrocarbon emissions during the comprehensive
performance test do not exceed the hydrocarbon emissions standard. In
addition, the limits you establish on the destruction and removal
efficiency (DRE) operating parameters required under paragraph (j) of
this section also ensure that you maintain compliance with the
hydrocarbon emission standard. If you do not conduct the hydrocarbon
demonstration and DRE tests concurrently, you must establish separate
operating parameter limits under paragraph (j) of this section based on
each test and the more restrictive of the operating parameter limits
applies.
(b) Other continuous monitoring systems (CMS). (1) You must use CMS
(e.g., thermocouples, pressure transducers, flow meters) to document
compliance with the applicable operating parameter limits under this
section.
(2) Except as specified in paragraphs (b)(2)(i) through (ii) of this
section, you must install and operate non-CMS in conformance with
Sec. 63.8(c)(3) that requires you, at a minimum, to comply with the
manufacturer's written specifications or recommendations for
installation, operation, and calibration of the system:
(i) Calibration of thermocouples. The calibration of a thermocouple
or other temperature sensor must be verified at least once every three
months; and
(ii) Accuracy and calibration of weight measurement devices. The
accuracy of weight measurement devices used to
[[Page 42]]
monitor flowrate of a feedstream (e.g., activated carbon feedrate,
sorbent feedrate, nonpumpable waste) must be 1 percent of
the weight being measured. The calibration of the device must be
verified at least once every three months.
(3) CMS must sample the regulated parameter without interruption,
and evaluate the detector response at least once each 15 seconds, and
compute and record the average values at least every 60 seconds.
(4) The span of the non-CEMS CMS detector must not be exceeded. You
must interlock the span limits into the automatic waste feed cutoff
system required by Sec. 63.1206(c)(3).
(5) Calculation of rolling averages--(i) Calculation of rolling
averages initially. Continuous monitoring systems must begin recording
one-minute average values at 12:01 am on the compliance data and begin
recording rolling averages when enough one-minute average values are
available to calculate the required rolling average (e.g., when 60 one-
minute averages are available to calculate an hourly rolling average;
when 720 one-minute averages are available to calculate a 12-hour
rolling average).
(ii) Calculation of rolling averages upon intermittent operations.
You must ignore periods of time when one-minute values are not available
for calculating rolling averages. When one-minute values become
available again, the first one-minute value is added to the previous
one-minute values to calculate rolling averages.
(iii) Calculation of rolling averages when the hazardous waste feed
is cutoff. (A) Except as provided by paragraph (b)(5)(iii)(B) of this
section, you must continue to monitoring operating parameter limits with
a CMS when the hazardous waste feed is cutoff if the source is
operating. You must not resume feeding hazardous waste if an operating
parameter exceeds its limit.
(B) You are not subject to the CMS requirements of this subpart
during periods of time you meet the requirements of
Sec. 63.1206(b)(1)(ii) (compliance with emissions standards for
nonhazardous waste burning sources when you are not burning hazardous
waste).
(c) Analysis of feedstreams--(1) General. Prior to feeding the
material, you must obtain an analysis of each feedstream that is
sufficient to document compliance with the applicable feedrate limits
provided by this section.
(2) Feedstream analysis plan. You must develop and implement a
feedstream analysis plan and record it in the operating record. The plan
must specify at a minimum:
(i) The parameters for which you will analyze each feedstream to
ensure compliance with the operating parameter limits of this section;
(ii) Whether you will obtain the analysis by performing sampling and
analysis or by other methods, such as using analytical information
obtained from others or using other published or documented data or
information;
(iii) How you will use the analysis to document compliance with
applicable feedrate limits (e.g., if you blend hazardous wastes and
obtain analyses of the wastes prior to blending but not of the blended,
as-fired, waste, the plan must describe how you will determine the
pertinent parameters of the blended waste);
(iv) The test methods which you will use to obtain the analyses;
(v) The sampling method which you will use to obtain a
representative sample of each feedstream to be analyzed using sampling
methods described in appendix I, part 26, of this chapter, or an
equivalent method; and
(vi) The frequency with which you will review or repeat the initial
analysis of the feedstream to ensure that the analysis is accurate and
up to date.
(3) Review and approval of analysis plan. You must submit the
feedstream analysis plan to the Administrator for review and approval,
if requested.
(4) Compliance with feedrate limits. To comply with the applicable
feedrate limits of this section, you must monitor and record feedrates
as follows:
(i) Determine and record the value of the parameter for each
feedstream by sampling and analysis or other method;
(ii) Determine and record the mass or volume flowrate of each
feedstream by a CMS. If you determine flowrate of a feedstream by
volume, you must determine and record the density of the
[[Page 43]]
feedstream by sampling and analysis (unless you report the constituent
concentration in units of weight per unit volume (e.g., mg/l)); and
(iii) Calculate and record the mass feedrate of the parameter per
unit time.
(5) Waiver of monitoring of constituents in certain feedstreams. You
are not required to monitor levels of metals or chlorine in the
following feedstreams to document compliance with the feedrate limits
under this section provided that you document in the comprehensive
performance test plan the expected levels of the constituent in the
feedstream and account for those assumed feedrate levels in documenting
compliance with feedrate limits: natural gas, process air, and
feedstreams from vapor recovery systems.
(d) Performance evaluations. (1) The requirements of Secs. 63.8(d)
(Quality control program) and (e) (Performance evaluation of continuous
monitoring systems) apply, except that you must conduct performance
evaluations of components of the CMS under the frequency and procedures
(for example, submittal of performance evaluation test plan for review
and approval) applicable to performance tests as provided by
Sec. 63.1207.
(2) You must comply with the quality assurance procedures for CEMS
prescribed in the appendix to this subpart.
(e) Conduct of monitoring. The provisions of Sec. 63.8(b) apply.
(f) Operation and maintenance of continuous monitoring systems. The
provisions of Sec. 63.8(c) apply except:
(1) Section 63.8(c)(3). The requirements of Sec. 63.1211(d), that
requires CMSs to be installed, calibrated, and operational on the
compliance date, shall be complied with instead of section 63.8(c)(3);
(2) Section 63.8(c)(4)(ii). The performance specifications for
carbon monoxide, hydrocarbon, and oxygen CEMSs in subpart B, part 60 of
this chapter that requires detectors to measure the sample concentration
at least once every 15 seconds for calculating an average emission rate
once every 60 seconds shall be complied with instead of section
63.8(c)(4)(ii); and
(3) Sections 63.8(c)(4)(i), (c)(5), and (c)(7)(i)(C) pertaining to
COMS apply only to owners and operators of hazardous waste burning
cement kilns..
(g) Alternative monitoring requirements other than continuous
emissions monitoring systems (CEMS)--(1) Requests to use alternative
methods. (i) You may submit an application to the Administrator under
this paragraph for approval of alternative monitoring requirements to
document compliance with the emission standards of this subpart. For
requests to use additional CEMS, however, you must use paragraph (a)(5)
of this section and Sec. 63.8(f).
(A) The Administrator will not approve averaging periods for
operating parameter limits longer than specified in this section unless
you document using data or information that the longer averaging period
will ensure that emissions do not exceed levels achieved during the
comprehensive performance test over any increment of time equivalent to
the time required to conduct three runs of the performance test.
(B) If the Administrator approves the application to use an
alternative monitoring requirement, you must continue to use that
alternative monitoring requirement until you receive approval under this
paragraph to use another monitoring requirement.
(ii) You may submit an application to waive an operating parameter
limit specified in this section based on documentation that neither that
operating parameter limit nor an alternative operating parameter limit
is needed to ensure compliance with the emission standards of this
subpart.
(iii) You must comply with the following procedures for applications
submitted under paragraphs (g)(1)(i) and (ii) of this section:
(A) Timing of the application. You must submit the application to
the Administrator not later than with the comprehensive performance test
plan.
(B) Content of the application. You must include in the application:
(1) Data or information justifying your request for an alternative
monitoring requirement (or for a waiver of an operating parameter
limit), such as the technical or economic infeasibility or the
impracticality of using the required approach;
[[Page 44]]
(2) A description of the proposed alternative monitoring
requirement, including the operating parameter to be monitored, the
monitoring approach/technique (e.g., type of detector, monitoring
location), the averaging period for the limit, and how the limit is to
be calculated; and
(3) Data or information documenting that the alternative monitoring
requirement would provide equivalent or better assurance of compliance
with the relevant emission standard, or that it is the monitoring
requirement that best assures compliance with the standard and that is
technically and economically practicable.
(C) Approval of request to use an alternative monitoring requirement
or waive an operating parameter limit. The Administrator will notify you
of approval or intention to deny approval of the request within 90
calendar days after receipt of the original request and within 60
calendar days after receipt of any supplementary information that you
submit. The Administrator will not approve an alternative monitoring
request unless the alternative monitoring requirement provides
equivalent or better assurance of compliance with the relevant emission
standard, or is the monitoring requirement that best assures compliance
with the standard and that is technically and economically practicable.
Before disapproving any request, the Administrator will notify you of
the Administrator's intention to disapprove the request together with:
(1) Notice of the information and findings on which the intended
disapproval is based; and
(2) Notice of opportunity for you to present additional information
to the Administrator before final action on the request. At the time the
Administrator notifies you of intention to disapprove the request, the
Administrator will specify how much time you will have after being
notified of the intended disapproval to submit the additional
information.
(D) Responsibility of owners and operators. You are responsible for
ensuring that you submit any supplementary and additional information
supporting your application in a timely manner to enable the
Administrator to consider your application during review of the
comprehensive performance test plan. Neither your submittal of an
application, nor the Administrator's failure to approve or disapprove
the application, relieves you of the responsibility to comply with the
provisions of this subpart.
(2) Administrator's discretion to specify additional or alternative
requirements. The Administrator may determine on a case-by-case basis at
any time (e.g., during review of the comprehensive performance test
plan, during compliance certification review) that you may need to limit
additional or alternative operating parameters (e.g., opacity in
addition to or in lieu of operating parameter limits on the particulate
matter control device) or that alternative approaches to establish
limits on operating parameters may be necessary to document compliance
with the emission standards of this subpart.
(h) Reduction of monitoring data. The provisions of Sec. 63.8(g)
apply.
(i) When an operating parameter is applicable to multiple standards.
Paragraphs (j) through (p) of this section require you to establish
limits on operating parameters based on comprehensive performance
testing to ensure you maintain compliance with the emission standards of
this subpart. For several parameters, you must establish a limit for the
parameter to ensure compliance with more than one emission standard. An
example is a limit on minimum combustion chamber temperature to ensure
compliance with both the DRE standard of paragraph (j) of this section
and the dioxin/furan standard of paragraph (k) of this section. If the
performance tests for such standards are not performed simultaneously,
the most stringent limit for a parameter derived from independent
performance tests applies.
(j) DRE. To remain in compliance with the destruction and removal
efficiency (DRE) standard, you must establish operating limits during
the comprehensive performance test (or during a previous DRE test under
provisions of Sec. 63.1206(b)(7)) for the following parameters, unless
the limits are based on manufacturer specifications, and comply with
those limits at
[[Page 45]]
all times that hazardous waste remains in the combustion chamber (i.e.,
the hazardous waste residence time has not transpired since the
hazardous waste feed cutoff system was activated):
(1) Minimum combustion chamber temperature. (i) You must measure the
temperature of each combustion chamber at a location that best
represents, as practicable, the bulk gas temperature in the combustion

(ii) You must establish a minimum hourly rolling average limit as
the average of the test run averages;
(2) Maximum flue gas flowrate or production rate. (i) As an
indicator of gas residence time in the control device, you must
establish and comply with a limit on the maximum flue gas flowrate, the
maximum production rate, or another parameter that you document in the
site-specific test plan as an appropriate surrogate for gas residence
time, as the average of the maximum hourly rolling averages for each
run.
(ii) You must comply with this limit on a hourly rolling average
basis;

device. (i) For hazardous waste burning incinerators and cement kilns,
if the combustor is equipped with an electrostatic precipitator,
baghouse (fabric filter), or other dry emissions control device where
particulate matter is suspended in contact with combustion gas, you must
establish a limit on the maximum temperature of the gas at the inlet to
the device on an hourly rolling average. You must establish the hourly
rolling average limit as the average of the test run averages.
(ii) For hazardous waste burning lightweight aggregate kilns, you
must establish a limit on the maximum temperature of the gas at the exit
of the (last) combustion chamber (or exit of any waste heat recovery
system) on an hourly rolling average. The limit must be established as
the average of the test run averages;
(2) Minimum combustion chamber temperature. (i) You must measure the
temperature of each combustion chamber at a location that best
represents, as practicable, the bulk gas temperature in the combustion
zone. You must document the temperature measurement location in the test
plan you submit under Secs. 63.1207(e) and (f);
(ii) You must establish a minimum hourly rolling average limit as
the average of the test run averages.
(3) Maximum flue gas flowrate or production rate. (i) As an
indicator of gas residence time in the control device, you must
establish and comply with a limit on the maximum flue gas flowrate, the
maximum production rate, or another parameter that you document in the
site-specific test plan as an appropriate surrogate for gas residence
time, as the average of the maximum hourly rolling averages for each
run.
(ii) You must comply with this limit on a hourly rolling average
basis;
(4) Maximum waste feedrate. (i) You must establish limits on the
maximum pumpable and total (pumpable and nonpumpable) waste feedrate for

(iii) Carbon specification. (A) You must specify and use the brand
(i.e., manufacturer) and type of carbon used during the comprehensive
performance test until a subsequent comprehensive performance test is
conducted, unless you document in the site-specific performance test
plan required under Secs. 63.1207(e) and (f) key parameters that affect
adsorption and establish limits on those parameters based on the carbon
used in the performance test.
(B) You may substitute at any time a different brand or type of
carbon provided that the replacement has equivalent or improved
properties compared to the carbon used in the performance test and
conforms to the key sorbent parameters you identify under paragraph
(k)(6)(iii)(A) of this section. You must include in the operating record
documentation that the substitute carbon will provide the same level of
control as the original carbon.
(7) Carbon bed parameter limits. If your combustor is equipped with
a carbon bed system:
(i) Maximum bed age. (A) Except as provided by paragraph
(k)(7)(i)(C) of this section, the maximum age of the carbon in each
segment of the bed before you must replace the carbon is the age of the
bed during the comprehensive performance test.
(B) You must measure carbon age in terms of the cumulative volume of
combustion gas flow through carbon since its addition. For beds with
multiple segments, you must establish the maximum age for each segment.
(C) For the initial comprehensive performance test, you may base the
initial limit on maximum age of the carbon in each segment of the bed on
manufacturer's specifications. If you use manufacturer's specifications
rather than actual bed age to establish the initial limit, you must also
recommend in the initial comprehensive performance test plan a schedule
for subsequent dioxin/furan emissions testing, prior to the confirmatory
performance test, that you will use to document to the Administrator
that the initial limit on maximum bed age ensures compliance with the
dioxin/furan emission standard. If you fail to confirm compliance with
the emission standard during this testing, you must conduct additional
testing as necessary to document that a revised lower limit on maximum
bed age ensures compliance with the standard.
(ii) Carbon specification. (A) You must specify and use the brand
(i.e., manufacturer) and type of carbon used during the comprehensive
performance test until a subsequent comprehensive performance test is
conducted, unless you document in the site-specific performance test
plan required under Secs. 63.1207(e) and (f) key parameters that affect
adsorption and establish limits on those parameters based on the carbon
used in the performance test.
(B) You may substitute at any time a different brand or type of
carbon provided that the replacement has equivalent or improved
properties compared to the carbon used in the performance test. You must
include in the operating record documentation that the substitute carbon
will provide an equivalent or improved level of control as the original
carbon.
(iii) Maximum temperature. You must measure the temperature of the
carbon bed at either the bed inlet or exit and
[[Page 47]]
you must establish a maximum temperature limit on an hourly rolling
average as the average of the test run averages.
(8) Catalytic oxidizer parameter limits. If your combustor is
equipped with a catalytic oxidizer, you must establish limits on the
following parameters:

rated volumetric flow of combustion gas through the catalyst divided by
the volume of the catalyst; and
(C) Substrate construction, including materials of construction,
washcoat type, and pore density.
(iv) Maximum flue gas temperature. You must establish a maximum flue
gas temperature limit at the entrance of the catalyst as an hourly

minimum inhibitor feedrate on an hourly rolling average as the average
of the test run averages.
(ii) Inhibitor specifications. (A) You must specify and use the
brand (i.e., manufacturer) and type of inhibitor used during the
comprehensive performance test until a subsequent comprehensive
performance test is conducted, unless you document in the site-specific
performance test plan required under Secs. 63.1207(e) and (f) key
parameters that affect the effectiveness of the inhibitor and establish
limits on those parameters based on the inhibitor used in the
performance test.
(B) You may substitute at any time a different brand or type of
inhibitor provided that the replacement has equivalent or improved
properties compared to the inhibitor used in the performance test and
conforms to the key parameters you identify under paragraph
(k)(9)(ii)(A) of this section. You must include in the operating record
documentation that the substitute inhibitor will provide the same level
of control as the original inhibitor.
(l) Mercury. You must comply with the mercury emission standard by
establishing and complying with the following operating parameter
limits. You must base the limits on operations during the comprehensive
performance test, unless the limits are based on manufacturer
specifications.
(1) Feedrate of total mercury. You must establish a 12-hour rolling
average limit for the total feedrate of mercury in all feedstreams as
the average of the hourly rolling averages for each run, unless mercury
feedrate limits are extrapolated from performance test feedrate levels
under the following provisions.
(i) You may request as part of the performance test plan under
Secs. 63.7(b) and (c) and Secs. 63.1207(e) and (f) to use the mercury
feedrates and associated emission rates during the comprehensive
performance test to extrapolate to higher allowable feedrate limits and
emission rates.
(ii) The extrapolation methodology will be reviewed and approved, as
warranted, by the Administrator. The review will consider in particular
whether:
(A) Performance test metal feedrates are appropriate (i.e., whether
feedrates are at least at normal levels; depending on the heterogeneity
of the waste, whether some level of spiking would be appropriate; and
whether the physical form and species of spiked material is
appropriate); and
(B) Whether the extrapolated feedrates you request are warranted
considering historical metal feedrate data.
[[Page 48]]
(iii) The Administrator will review the performance test results in
making a finding of compliance required by Secs. 63.6(f)(3) and
63.1206(b)(3) to ensure that you have interpreted emission test results
properly and that the extrapolation procedure is appropriate for your
source.

collision, or free jet wet scrubbers, and low energy wet scrubbers such
as spray towers, packed beds, or tray towers, you must establish limits
on the following parameters:
(A) For high energy scrubbers only, minimum pressure drop across the
wet scrubber on an hourly rolling average, established as the average of
the test run averages;
(B) For all wet scrubbers:
(1) To ensure that the solids content of the scrubber liquid does
not exceed levels during the performance test, you must either:
(i) Establish a limit on solids content of the scrubber liquid using
a CMS or by manual sampling and analysis. If you elect to monitor solids
content manually, you must sample and analyze the scrubber liquid hourly
unless you support an alternative monitoring frequency in the
performance test plan that you submit for review and approval; or
(ii) Establish a minimum blowdown rate using a CMS and either a
minimum scrubber tank volume or liquid level using a CMS.
(2) For maximum solids content monitored with a CMS, you must
establish a limit on a twelve-hour rolling average as the average of the
test run averages.
(3) For maximum solids content measured manually, you must establish
an hourly limit, as measured at least once per hour, unless you support
an alternative monitoring frequency in the performance test plan that
you submit for review and approval. You must establish the maximum
hourly limit as the average of the manual measurement averages for each
run.
(4) For minimum blowdown rate and either a minimum scrubber tank
volume or liquid level using a CMS, you must establish a limit on an
hourly rolling average as the average of the test run averages.
(C) For high energy wet scrubbers only, you must establish limits on
either the minimum liquid to gas ratio or the minimum scrubber water
flowrate and maximum flue gas flowrate on an hourly rolling average. If
you establish limits on maximum flue gas flowrate under this paragraph,
you need not establish a limit on maximum flue gas flowrate under
paragraph (m)(2) of this section. You must establish these hourly
rolling average limits as the average of the test run averages; and
(D) You must establish limits on minimum power input for ionizing
wet scrubbers on an hourly rolling average as the average of the test
run averages.
(ii) Baghouses. If your combustor is equipped with a baghouse, you
must establish a limit on minimum pressure drop and maximum pressure
drop across each baghouse cell based on manufacturer's specifications.
You must comply with the limit on an hourly rolling average.
(iii) Electrostatic precipitators. If your combustor is equipped
with an electrostatic precipitator, you must establish a limit on
minimum secondary power
[[Page 49]]
input (kVa) for each field on an hourly rolling average as the average
of the test run averages. Secondary power is power actually fed to the
electrostatic precipitator rather than primary power fed to the
transformer-rectifier sets.
(iv) Other particulate matter control devices. For each control
device that is not a high energy or ionizing wet scrubber, baghouse, or
electrostatic precipitator but is operated to comply with the
particulate matter emission standards of this subpart, you must ensure
that the control device is properly operated and maintained as required
by Sec. 63.1206(c)(7) and by monitoring the operation of the control
device as follows:
(A) During each comprehensive performance test conducted to
demonstrate compliance with the particulate matter emissions standard,
you must establish a range of operating values for the control device
that is a representative and reliable indicator that the control device
is operating within the same range of conditions as during the
performance test. You must establish this range of operating values as
follows:
(1) You must select a set of operating parameters appropriate for
the control device design that you determine to be a representative and
reliable indicator of the control device performance.
(2) You must measure and record values for each of the selected
operating parameters during each test run of the performance test. A
value for each selected parameter must be recorded using a continuous
monitor.
(3) For each selected operating parameter measured in accordance
with the requirements of paragraph (m)(1)(iv)(A)(1) of this section, you
must establish a minimum operating parameter limit or a maximum
operating parameter limit, as appropriate for the parameter, to define
the operating limits within which the control device can operate and
still continuously achieve the same operating conditions as during the
performance test.
(4) You must prepare written documentation to support the operating
parameter limits established for the control device and you must include
this documentation in the performance test plan that you submit for
review and approval. This documentation must include a description for
each selected parameter and the operating range and monitoring frequency
required to ensure the control device is being properly operated and
maintained.
(B) You must install, calibrate, operate, and maintain a monitoring
device equipped with a recorder to measure the values for each operating
parameter selected in accordance with the requirements of paragraph
(m)(1)(iv)(A)(1) of this section. You must install, calibrate, and
maintain the monitoring equipment in accordance with the equipment
manufacturer's specifications. The recorder must record the detector
responses at least every 60 seconds, as required in the definition of
continuous monitor.
(C) You must regularly inspect the data recorded by the operating
parameter monitoring system at a sufficient frequency to ensure the
control device is operating properly. An excursion is determined to have
occurred any time that the actual value of a selected operating
parameter is less than the minimum operating limit (or, if applicable,
greater than the maximum operating limit) established for the parameter
in accordance with the requirements of paragraph (m)(1)(iv)(A)(3) of
this section.
(D) Operating parameters selected in accordance with paragraph
(m)(1)(iv) of this section may be based on manufacturer specifications
provided you support the use of manufacturer specifications in the
performance test plan that you submit for review and approval.
(2) Maximum flue gas flowrate or production rate. (i) As an
indicator of gas residence time in the control device, you must
establish a limit on the maximum flue gas flowrate, the maximum
production rate, or another parameter that you document in the site-
specific test plan as an appropriate surrogate for gas residence time,
as the average of the maximum hourly rolling averages for each run.
(ii) You must comply with this limit on a hourly rolling average
basis;
(3) Maximum ash feedrate. Owners and operators of hazardous waste
incinerators must establish a maximum ash feedrate limit as the average
of the highest hourly rolling averages for each run.
[[Page 50]]
(n) Semivolatile metals and low volatility metals. You must comply
with the semivolatile metal (cadmium and lead) and low volatile metal
(arsenic, beryllium, and chromium) emission standards by establishing
and complying with the following operating parameter limits. You must
base the limits on operations during the comprehensive performance test,
unless the limits are based on manufacturer specifications.
(1) Maximum inlet temperature to dry particulate matter air
pollution control device. You must establish a limit on the maximum
inlet temperature to the primary dry metals emissions control device
(e.g., electrostatic precipitator, baghouse) on an hourly rolling
average basis as the average of the test run averages.
(2) Maximum feedrate of semivolatile and low volatile metals. (i)
General. You must establish feedrate limits for semivolatile metals
(cadmium and lead) and low volatile metals (arsenic, beryllium, and
chromium) as follows, except as provided by paragraph (n)(2)(ii) of this

average of the average hourly rolling averages for each run;
(B) You must establish a 12-hour rolling average limit for the
feedrate of arsenic, beryllium, and chromium, combined, in all
feedstreams as the average of the average hourly rolling averages for
each run; and
(C) You must establish a 12-hour rolling average limit for the
feedrate of arsenic, beryllium, and chromium, combined, in all pumpable
feedstreams as the average of the average hourly rolling averages for
each run. Dual feedrate limits for both pumpable and total feedstreams
are not required, however, if you base the total feedrate limit solely
on the feedrate of pumpable feedstreams.
(ii) Feedrate extrapolation. (A) You may request as part of the
performance test plan under Secs. 63.7(b) and (c) and Secs. 63.1207(e)
and (f) to use the semivolatile metal and low volatile metal feedrates
and associated emission rates during the comprehensive performance test
to extrapolate to higher allowable feedrate limits and emission rates.
(B) The extrapolation methodology will be reviewed and approved, as
warranted, by the Administrator. The review will consider in particular
whether:
(1) Performance test metal feedrates are appropriate (i.e., whether
feedrates are at least at normal levels; depending on the heterogeneity
of the waste, whether some level of spiking would be appropriate; and
whether the physical form and species of spiked material is
appropriate); and
(2) Whether the extrapolated feedrates you request are warranted
considering historical metal feedrate data.
(C) The Administrator will review the performance test results in
making a finding of compliance required by Secs. 63.6(f)(3) and
63.1206(b)(3) to ensure that you have interpreted emission test results
properly and that the extrapolation procedure is appropriate for your
source.
(3) Control device operating parameter limits (OPLs). You must
establish operating parameter limits on the particulate matter control
device as specified by paragraph (m)(1) of this section;
(4) Maximum total chlorine and chloride feedrate. You must establish
a 12-hour rolling average limit for the feedrate of total chlorine and
chloride in all feedstreams as the average of the average hourly rolling
averages for each run.

production rate, or another parameter that you document in the site-
specific test plan as an appropriate surrogate for gas residence time,
as the average of the maximum hourly rolling averages for each run.
(ii) You must comply with this limit on a hourly rolling average
basis.
(o) Hydrochloric acid and chlorine gas. You must comply with the
hydrogen chloride and chlorine gas emission
[[Page 51]]
standard by establishing and complying with the following operating
parameter limits. You must base the limits on operations during the
comprehensive performance test, unless the limits are based on
manufacturer specifications.
(1) Feedrate of total chlorine and chloride. You must establish a
12-hour rolling average limit for the total feedrate of chlorine
(organic and inorganic) in all feedstreams as the average of the average
hourly rolling averages for each run.
(2) Maximum flue gas flowrate or production rate. (i) As an
indicator of gas residence time in the control device, you must
establish a limit on the maximum flue gas flowrate, the maximum
production rate, or another parameter that you document in the site-
specific test plan as an appropriate surrogate for gas residence time,
as the average of the maximum hourly rolling averages for each run.
(ii) You must comply with this limit on a hourly rolling average
basis;
(3) Wet scrubber. If your combustor is equipped with a wet scrubber:

as a venturi, hydrosonic, collision, or free jet wet scrubber, you must
establish a limit on minimum pressure drop across the wet scrubber on an
hourly rolling average as the average of the test run averages;
(ii) If your source is equipped with a low energy wet scrubber such
as a spray tower, packed bed, or tray tower, you must establish a
minimum pressure drop across the wet scrubber based on manufacturer's
specifications. You must comply with the limit on an hourly rolling
average;
(iii) If your source is equipped with a low energy wet scrubber, you
must establish a limit on minimum liquid feed pressure to the wet
scrubber based on manufacturer's specifications. You must comply with
the limit on an hourly rolling average;
(iv) You must establish a limit on minimum pH on an hourly rolling
average as the average of the test run averages;
(v) You must establish limits on either the minimum liquid to gas
ratio or the minimum scrubber water flowrate and maximum flue gas
flowrate on an hourly rolling average as the average of the test run
averages. If you establish limits on maximum flue gas flowrate under
this paragraph, you need not establish a limit on maximum flue gas
flowrate under paragraph (o)(2) of this section; and
(vi) You must establish a limit on minimum power input for ionizing
wet scrubbers on an hourly rolling average as the average of the test
run averages.
(4) Dry scrubber. If your combustor is equipped with a dry scrubber,
you must establish the following operating parameter limits:

performance test until a subsequent comprehensive performance test is
conducted, unless you document in the site-specific performance test
plan required under Secs. 63.1207(e) and (f) key parameters that affect
adsorption and establish limits on those parameters based on the sorbent
used in the performance test.
(B) You may substitute at any time a different brand or type of
sorbent provided that the replacement has equivalent or improved
properties compared to the sorbent used in the performance test and
conforms to the key sorbent parameters you identify under paragraph
(o)(4)(iii)(A) of this section. You must record in the operating record
documentation that the substitute sorbent will provide the same level of
control as the original sorbent.
(p) Maximum combustion chamber pressure. If you comply with the
requirements for combustion system leaks under Sec. 63.1206(c)(5) by
maintaining the maximum combustion chamber zone pressure lower than
ambient pressure, you must monitor the pressure instantaneously and the
automatic waste
[[Page 52]]
feed cutoff system must be engaged when negative pressure is not
maintained at any time.
(q) Operating under different modes of operation. If you operate
under different modes of operation, you must establish operating
parameter limits for each mode. You must document in the operating
record when you change a mode of operation and begin complying with the
operating parameter limits for an alternative mode of operation. You
must begin calculating rolling averages anew (i.e., without considering
previous recordings) when you begin complying with the operating
parameter limits for the alternative mode of operation.

Appendix to Subpart EEE of Part 63--Quality Assurance Procedures for
Continuous Emissions Monitors Used for Hazardous Waste Combustors
1. Applicability and Principle
1.1 Applicability. a. These quality assurance requirements are used
to evaluate the effectiveness of quality control (QC) and quality
assurance (QA) procedures and the quality of data produced by continuous
emission monitoring systems (CEMS) that are used for determining
compliance with the emission standards on a continuous basis as
specified in the applicable regulation. The QA procedures specified by
these requirements represent the minimum requirements necessary for the
control and assessment of the quality of CEMS data used to demonstrate
compliance with the emission standards provided under subpart EEE of
this part 63. Owners and operators must meet these minimum requirements
and are encouraged to develop and implement a more extensive QA program.
These requirements superede those found in part 60, appendix F of this
chapter. Appendix F does not apply to hazardous waste-burning devices.
b. Data collected as a result of the required QA and QC measures are
to be recorded in the operating record. In addition, data collected as a
result of CEMS performance evaluations required by Section 5 in
conjunction with an emissions performance test are to be submitted to
the Administrator as provided by Sec. 63.8(e)(5). These data are to be
used by both the Agency and the CEMS operator in assessing the
effectiveness of the CEMS QA and QC procedures in the maintenance of
acceptable CEMS operation and valid emission data.
1.2 Principle. The QA procedures consist of two distinct and
equally important functions. One function is the assessment of the
quality of the CEMS data by estimating accuracy. The other function is
the control and improvement of the quality of the CEMS data by
implementing QC policies and corrective actions. These two functions
form a control loop. When the assessment function indicates that the
data quality is inadequate, the source must immediately stop burning
hazardous waste. The CEM data control effort must be increased until the
data quality is acceptable before hazardous waste burning can resume.
a. In order to provide uniformity in the assessment and reporting of
data quality, this procedure explicitly specifies the assessment methods
for response drift and accuracy. The methods are based on procedures
included in the applicable performance specifications provided in
appendix B to part 60 of this chapter. These procedures also require the
analysis of the EPA audit samples concurrent with certain reference
method (RM) analyses as specified in the applicable RM's.
b. Because the control and corrective action function encompasses a
variety of policies, specifications, standards, and corrective measures,
this procedure treats QC requirements in general terms to allow each
source owner or operator to develop a QC system that is most effective
and efficient for the circumstances.
2. Definitions
2.1 Continuous Emission Monitoring System (CEMS). The total
equipment required for the determination of a pollutant concentration.
The system consists of the following major subsystems:
2.1.1 Sample Interface. That portion of the CEMS used for one or
more of the following: sample acquisition, sample transport, and sample
conditioning, or protection of the monitor from the effects of the stack
effluent.
[[Page 61]]
2.1.2 Pollutant Analyzer. That portion of the CEMS that senses the
pollutant concentration and generates a proportional output.
2.1.3 Diluent Analyzer. That portion of the CEMS that senses the
diluent gas (O2) and generates an output proportional to the gas
concentration.
2.1.4 Data Recorder. That portion of the CEMS that provides a
permanent record of the analyzer output. The data recorder may provide
automatic data reduction and CEMS control capabilities.
2.2 Relative Accuracy (RA). The absolute mean difference between
the pollutant concentration determined by the CEMS and the value
determined by the reference method (RM) plus the 2.5 percent error
confidence coefficient of a series of test divided by the mean of the RM
tests or the applicable emission limit.
2.3 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
took place.
2.4 Zero Drift (ZD). The difference in CEMS output readings at the
zero pollutant level after a stated period of operation during which no
unscheduled maintenance, repair, or adjustment took place.
2.5 Calibration Standard. Calibration standards produce a known and
unchanging response when presented to the pollutant analyzer portion of
the CEMS, and are used to calibrate the drift or response of the
analyzer.
2.6 Relative Accuracy Test Audit (RATA). Comparison of CEMS
measurements to reference method measurements in order to evaluate
relative accuracy following procedures and specification given in the
appropriate performance specification.
2.7 Absolute Calibration Audit (ACA). Equivalent to calibration
error (CE) test defined in the appropriate performance specification
using NIST traceable calibration standards to challenge the CEMS and
assess accuracy.
2.8 Rolling Average. The average emissions, based on some
(specified) time period, calculated every minute from a one-minute
average of four measurements taken at 15-second intervals. CEMS other
than carbon monoxide and total hydrocarbon CEMS may have rolling
averages calculated every hour from a one-hour average of at least four
measurements taken at intervals not exceeding 15 minutes.
c. QA/QC Requirements
3.1 QC Requirements. a. Each owner or operator must develop and
implement a QC program. At a minimum, each QC program must include
written procedures describing in detail complete, step-by-step
procedures and operations for the following activities.
1. Checks for component failures, leaks, and other abnormal
conditions.
2. Calibration of CEMS.
3. CD determination and adjustment of CEMS.
4. Integration of CEMS with the automatic waste feed cutoff (AWFCO)
system.
5. Preventive Maintenance of CEMS (including spare parts inventory).
6. Data recording, calculations, and reporting.
7. Checks of record keeping.
8. Accuracy audit procedures, including sampling and analysis
methods.
9. Program of corrective action for malfunctioning CEMS.
10. Operator training and certification.
11. Maintaining and ensuring current certification or naming of
cylinder gasses, metal solutions, and particulate samples used for audit
and accuracy tests, daily checks, and calibrations.
b. Whenever excessive inaccuracies occur for two consecutive
quarters, the current written procedures must be revised or the CEMS
modified or replaced to correct the deficiency causing the excessive
inaccuracies. These written procedures must be kept on record and
available for inspection by the enforcement agency.
3.2 QA Requirements. Each source owner or operator must develop and
implement a QA plan that includes, at a minimum, the following.
1. QA responsibilities (including maintaining records, preparing
reports, reviewing reports).
2. Schedules for the daily checks, periodic audits, and preventive
maintenance.
3. Check lists and data sheets.
4. Preventive maintenance procedures.
5. Description of the media, format, and location of all records and
reports.
6. Provisions for a review of the CEMS data at least once a year.
Based on the results of the review, the owner or operator must revise or
update the QA plan, if necessary.
d. CD and ZD Assessment and Daily System Audit
4.1 CD and ZD Requirement. Owners and operators must check, record,
and quantify the ZD and the CD at least once daily (approximately 24
hours) in accordance with the method prescribed by the manufacturer. The
CEMS calibration must, at a minimum, be adjusted whenever the daily ZD
or CD exceeds the limits in the Performance Specifications. If, on any
given ZD and/or CD check the ZD and/or CD exceed(s) two times the limits
in the Performance Specifications, or if the cumulative adjustment to
the ZD and/or CD (see Section 4.2) exceed(s) three
[[Page 62]]
times the limits in the Performance Specifications, hazardous waste
burning must immediately cease and the CEMS must be serviced and
recalibrated. Hazardous waste burning cannot resume until the owner or
operator documents that the CEMS is in compliance with the Performance
Specifications by carrying out an ACA.
4.2 Recording Requirements for Automatic ZD and CD Adjusting
Monitors. Monitors that automatically adjust the data to the corrected
calibration values must record the unadjusted concentration measurement
prior to resetting the calibration, if performed, or record the amount
of the adjustment.
4.3 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, etc.)
as appropriate.
4.4 Data Recording and Reporting. All measurements from the CEMS
must be retained in the operating record for at least 5 years.
5. Performance Evaluation
Carbon Monoxide (CO), Oxygen (O2), and Hydrocarbon (HC)
CEMS. An Absolute Calibration Audit (ACA) must be conducted quarterly,
and a Relative Accuracy Test Audit (RATA) (if applicable, see sections
5.1 and 5.2) must be conducted yearly. An Interference Response Tests
must be performed whenever an ACA or a RATA is conducted. When a
performance test is also required under Sec. 63.1207 to document
compliance with emission standards, the RATA must coincide with the
performance test. The audits must be conducted as follows.
5.1 Relative Accuracy Test Audit (RATA). This requirement applies
to O2 and CO CEMS. The RATA must be conducted at least
yearly. Conduct the RATA as described in the RA test procedure (or
alternate procedures section) described in the applicable Performance
Specifications. In addition, analyze the appropriate performance audit
samples received from the EPA as described in the applicable sampling
methods.
5.2 Absolute Calibration Audit (ACA). The ACA must be conducted at
least quarterly except in a quarter when a RATA (if applicable, see
section 5.1) is conducted instead. Conduct an ACA as described in the
calibration error (CE) test procedure described in the applicable
Performance Specifications.
5.3 Interference Response Test. The interference response test must
be conducted whenever an ACA or RATA is conducted. Conduct an
interference response test as described in the applicable Performance
Specifications.
5.4 Excessive Audit Inaccuracy. If the RA from the RATA or the CE
from the ACA exceeds the criteria in the applicable Performance
Specifications, hazardous waste burning must cease immediately.
Hazardous waste burning cannot resume until the owner or operator takes
corrective measures and audit the CEMS with a RATA to document that the
CEMS is operating within the specifications.
6. Other Requirements
6.1 Performance Specifications. CEMS used by owners and operators
of HWCs must comply with the following performance specifications in
appendix B to part 60 of this chapter:
Table I: Performance Specifications for CEMS
------------------------------------------------------------------------
Performance
CEMS specification
------------------------------------------------------------------------
Carbon monoxide.......................................... 4B
Oxygen................................................... 4B
Total hydrocarbons....................................... 8A
------------------------------------------------------------------------
6.2 Downtime due to Calibration. Facilities may continue to burn
hazardous waste for a maximum of 20 minutes while calibrating the CEMS.
If all CEMS are calibrated at once, the facility must have twenty
minutes to calibrate all the CEMS. If CEMS are calibrated individually,
the facility must have twenty minutes to calibrate each CEMS. If the
CEMS are calibrated individually, other CEMS must be operational while
the individual CEMS is being calibrated.
6.3 Span of the CEMS.
6.3.1 CO CEMS. The CO CEM must have two ranges, a low range with a
span of 200 ppmv and a high range with a span of 3000 ppmv at an oxygen
correction factor of 1. A one-range CEM may be used, but it must meet
the performance specifications for the low range in the specified span
of the low range.
6.3.2 O2 CEMS. The O2 CEM must have a span of
25 percent. The span may be higher than 25 percent if the O2
concentration at the sampling point is greater than 25 percent.
6.3.3 HC CEMS. The HC CEM must have a span of 100 ppmv, expressed
as propane, at an oxygen correction factor of 1.
6.3.4 CEMS Span Values. When the Oxygen Correction Factor is
Greater than 2. When an owner or operator installs a CEMS at a location
of high ambient air dilution, i.e., where the maximum oxygen correction
factor as determined by the permitting agency is greater than 2, the
owner or operator must install a CEM with a lower span(s), proportionate
to the larger oxygen correction factor, than those specified above.
6.3.5 Use of Alternative Spans. Owner or operators may request
approval to use alternative spans and ranges to those specified.
[[Page 63]]
Alternate spans must be approved in writing in advance by the
Administrator. In considering approval of alternative spans and ranges,
the Administrator will consider that measurements beyond the span will
be recorded as values at the maximum span for purposes of calculating
rolling averages.
6.3.6 Documentation of Span Values. The span value must be
documented by the CEMS manufacturer with laboratory data.
6.4.1 Moisture Correction. Method 4 of appendix A, part 60 of this
chapter, must be used to determine moisture content of the stack gasses.
6.4.2 Oxygen Correction Factor. Measured pollutant levels must be
corrected for the amount of oxygen in the stack according to the
following formula:
[GRAPHIC] [TIFF OMITTED] TR30SE99.022
Where:
Pc = concentration of the pollutant or standard corrected to
7 percent oxygen, dry basis;
Pm = measured concentration of the pollutant, dry basis;
E = volume fraction of oxygen in the combustion air fed into the device,
on a dry basis (normally 21 percent or 0.21 if only air is
fed);
Y = measured fraction of oxygen on a dry basis at the sampling point.
The oxygen correction factor is:
[GRAPHIC] [TIFF OMITTED] TR30SE99.023
6.4.3 Temperature Correction. Correction values for temperature are
obtainable from standard reference materials.
6.5 Rolling Average. A rolling average is the arithmetic average of
all one-minute averages over the averaging period.
6.5.1 One-Minute Average for CO and HC CEMS and Operating Parameter
Limits. One-minute averages are the arithmetic average of the four most
recent 15-second observations and must be calculated using the following
equation:
[GRAPHIC] [TIFF OMITTED] TR30SE99.024
Where:
c = the one minute average
ci = a fifteen-second observation from the CEM
Fifteen second observations must not be rounded or smoothed.
Fifteen-second observations may be disregarded only as a result of a
failure in the CEMS and allowed in the source's quality assurance plan
at the time of the CMS failure. One-minute averages must not be rounded,
smoothed, or disregarded.
6.5.2 Ten Minute Rolling Average Equation. The ten minute rolling
average must be calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR30SE99.025
Where:
CRA = The concentration of the standard, expressed as a
rolling average
ci = a one minute average
6.5.3 Hourly Rolling Average Equation for CO and THC CEMS and
Operating Parameter Limits. The rolling average, based on a specific
number integer of hours, must be calculated using the following
equation:
[GRAPHIC] [TIFF OMITTED] TR30SE99.026
Where:
cRA = The concentration of the standard, expressed as a
rolling average
ci = a one minute average
6.5.4 Averaging Periods for CEMS other than CO and THC. The
averaging period for CEMS other than CO and THC CEMS must be calculated
as a rolling average of all one-hour values over the averaging period.
An hourly average is comprised of 4 measurements taken at equally spaced
time intervals, or at most every 15 minutes. Fewer than 4 measurements
might be available within an hour for reasons such as facility downtime
or CEMS calibration. If at least two measurements (30 minutes of data)
are available, an hourly average must be calculated. The n-hour rolling
average is calculated by averaging the n most recent hourly averages.
6.6 Units of the Standards for the Purposes of Recording and
Reporting Emissions. Emissions must be recorded and reported expressed
after correcting for oxygen, temperature, and moisture. Emissions must
be reported in metric, but may also be reported in the English system of
units, at 7 percent oxygen, 20 deg.C, and on a dry basis.
6.7 Rounding and Significant Figures. Emissions must be rounded to
two significant figures using ASTM procedure E-29-90 or its successor.
Rounding must be avoided prior to rounding for the reported value.

that occurred during the year preceding September 21, 1998 for existing
affected sources. For new affected sources, predominant use will be
based on the first year after initial startup. The determination of
predominant use shall be reported in the Notification of Compliance
Status required by Sec. 63.1260(f). If the predominant use changes, the
redetermination of predominant use shall be reported in the next
Periodic Report.
(5) If the storage tank begins receiving material from (or sending
material to) another PMPU; or ceases to receive material from (or send
material to) a PMPU; or if the applicability of this subpart to a
storage tank has been determined according to the provisions of
paragraphs (e)(1) through (4) of this section and there is a significant
change in the use of the storage tank that could reasonably change the
predominant use, the owner or operator shall reevaluate the
applicability of this subpart to the storage tank, and report such
changes to EPA in the next Periodic report.
(f) Compliance dates. The compliance dates for affected sources are
as follows:
(1) An owner or operator of an existing affected source must comply
with the provisions of this subpart within 3 years after September 21,
1998.
(2) An owner or operator of a new or reconstructed affected source
must comply with the provisions of this subpart on September 21, 1998 or
upon startup, whichever is later.
[[Page 65]]
(3) Notwithstanding the requirements of paragraphs (f)(1) and (2) of
this section, a new source which commences construction or
reconstruction after April 2, 1997 and before September 21, 1998 shall
not be required to comply with such promulgated standard until 3 years
after September 21, 1998 if:
(i) The promulgated standard is more stringent than the proposed
standard; and
(ii) The owner or operator complies with the standard as proposed
during the 3-year period immediately after September 21, 1998.
(4) Pursuant to section 112(i)(3)(B) of the Act, an owner or
operator may request an extension allowing the existing source up to 1
additional year to comply with section 112(d) standards.
(i) For purposes of this subpart, a request for an extension shall
be submitted no later than 120 days prior to the compliance dates
specified in paragraphs (f)(1) through (3) of this section, except as
provided in paragraph (f)(4)(ii) of this section. The dates specified in
Sec. 63.6(i) for submittal of requests for extensions shall not apply to
sources subject to this subpart.
(ii) An owner or operator may submit a compliance extension request
after the date specified in paragraph (f)(4)(i) of this section provided
the need for the compliance extension arose after that date and before
the otherwise applicable compliance date, and the need arose due to
circumstances beyond reasonable control of the owner or operator. This
request shall include the data described in Sec. 63.6(i)(6)(i)(A), (B),
(C), and (D).
(g) Applicability of this subpart except during periods of startup,
shutdown, and malfunction. (1) Each provision set forth in this subpart
shall apply at all times except that emission limitations shall not
apply during periods of: startup; shutdown; and malfunction, if the
startup, shutdown, and malfunction precludes the ability of a particular
emission point of an affected source to comply with one or more specific
emission limitations to which it is subject and the owner or operator
follows the provisions for periods of startup, shutdown, and
malfunction, as specified in Secs. 63.1259(a)(3) and 63.1260(i).
Startup, shutdown, and malfunction are defined in Sec. 63.1251.
(2) The provisions set forth in Sec. 63.1255 of this subpart shall
apply at all times except during periods of nonoperation of the PMPU (or
specific portion thereof) in which the lines are drained and
depressurized resulting in the cessation of the emissions to which
Sec. 63.1255 of this subpart applies.
(3) The owner or operator shall not shut down items of equipment
that are required or utilized for compliance with the emissions
limitations of this subpart during times when emissions (or, where
applicable, wastewater streams or residuals) are being routed to such
items of equipment, if the shutdown would contravene emissions
limitations of this subpart applicable to such items of equipment. This
paragraph does not apply if the item of equipment is malfunctioning, or
if the owner or operator must shut down the equipment to avoid damage
due to a malfunction of the PMPU or portion thereof.
(4) During startups, shutdowns, and malfunctions when the emissions
limitations of this subpart do not apply pursuant to paragraphs (g)(1)
through (3) of this section, the owner or operator shall implement, to
the extent reasonably available, measures to prevent or minimize excess
emissions to the extent practical. For purposes of this paragraph,
``excess emissions'' means emissions in excess of those that would have
occurred if there were no startup, shutdown, or malfunction and the
owner or operator complied with the relevant provisions of this subpart.
The measures to be taken shall be identified in the applicable startup,
shutdown, and malfunction plan, and may include, but are not limited to,
air pollution control technologies, work practices, pollution
prevention, monitoring, and/or changes in the manner of operation of the
source. Back-up control devices are not required, but may be used if
available.

AA, BB, or CC, or is subject to monitoring and recordkeeping
requirements in 40 CFR part 265, subpart AA, BB, or CC and the owner or
operator complies with the periodic reporting requirements under 40 CFR
part 264, subpart AA, BB, or CC that would apply to the device if the
facility had final-permitted status, the owner or operator may elect to
comply either with the monitoring, recordkeeping, and reporting
requirements of this subpart, or with the monitoring, recordkeeping, and
reporting requirements in 40 CFR parts 264 and/or 265, as described in
this paragraph, which shall constitute compliance with the monitoring,
record keeping, and reporting requirements of this subpart. If the owner
or operator elects to comply with the monitoring, recordkeeping, and
reporting requirements in 40 CFR parts 264 and/or 265, the owner or
operator shall report all information required by Sec. 63.1260(g). The

specified in this section, a storage tank controlled with a floating
roof and in compliance with the provisions of 40 CFR 60.112b, subpart
Kb, constitutes compliance with the provisions of this subpart GGG. A
storage tank with a fixed roof, closed vent system, and control device
in compliance with the provisions of 40 CFR 60.112b, subpart Kb must
comply with the monitoring, recordkeeping, and reporting provisions of
this subpart GGG. The owner or operator shall identify in the
Notification of Compliance Status report required by Sec. 63.1260(f)
which tanks are in compliance with subpart Kb.

a pharmaceutical product. Cleaning operations conducted are considered
part of the process. The holding of the pharmaceutical product in tanks
or other holding equipment for more than 30 consecutive days, or
transfer of the pharmaceutical product to containers for shipment, marks
the end of a process, and the tanks are considered part of the PMPU that
produced the stored material. When material from one unit operation is
used as the feedstock for the production of two
[[Page 73]]
or more different pharmaceutical products, the unit operation is
considered the endpoint of the process that produced the material, and
the unit operations into which the material is routed mark the beginning
of the other processes. Nondedicated recovery devices located within a

recover material as an integral part of a process. The condenser must
support a vapor-to-liquid phase change for periods of source equipment
operation that are at or above the boiling or bubble point of
substance(s) at the liquid surface. Examples of process condensers
include distillation condensers, reflux condensers, and condensers used
in stripping or flashing operations. In a series of condensers, all
condensers up to and including the first condenser with an exit gas
temperature below the boiling or bubble point of the substance(s) at the
liquid surface are considered to be process condensers. All condensers
in line prior to a vacuum source are included in this definition.
Process shutdown means a work practice or operational procedure that
stops production from a process or part of a process during which it is
technically feasible to clear process material from a process or part of
a process consistent with safety constraints and during which repairs
can be effected. An unscheduled work practice or operational procedure
that stops production from a process or part of a process for less than
24 hours is not a process shutdown. An unscheduled work practice or
operational procedure that would stop production from a process or part
of a process for a shorter period of time than would be required to
clear the process or part of the process of materials and start up the
process, and would result in greater emissions than delay of repair of
leaking components until the next scheduled process shutdown, is not a
process shutdown. The use of spare equipment and technically feasible
bypassing of equipment without stopping production are not process
shutdowns.
Process tank means a tank that is used to collect material
discharged from a feedstock storage tank or unit operation within the
process and transfer this material to another unit operation within the
process or to a product storage tank. Surge control vessels and bottoms
receivers that fit these conditions are considered process tanks.
Process vent means a vent from a unit operation or vents from
multiple unit operations within a process that are manifolded together
into a common header, through which a HAP-containing gas stream is, or
has the potential to be, released to the atmosphere. Examples of process
vents include, but are not limited to, vents on condensers used for
product recovery, bottom receivers, surge control vessels, reactors,
filters, centrifuges, and process tanks. Emission streams that are
undiluted and uncontrolled containing less than 50 ppmv HAP, as
determined through process knowledge that no HAP are present in the
emission stream or using an engineering assessment as discussed in
Sec. 63.1257(d)(2)(ii), test data using Methods 18 of 40 CFR part 60,
appendix A, or any other test method that has been validated according
to the procedures in Method 301 of appendix A of this part, are not
considered process vents. Process vents do not include vents on storage
tanks regulated under Sec. 63.1253, vents on wastewater emission sources
regulated under Sec. 63.1256, or pieces of equipment regulated under
Sec. 63.1255.
Production-indexed HAP consumption factor is the result of dividing
the annual consumption of total HAP by the annual production rate, per
process.
Production-indexed volatile organic compound (VOC) consumption
factor is the result of dividing the annual consumption of total VOC by
the annual production rate, per process.
Publicly owned treatment works (POTW) means any devices and systems
used in the storage, treatment, recycling, and reclamation of municipal
sewage or industrial wastes of a liquid
[[Page 74]]
nature as defined in section 212(2)(A) of the Clean Water Act, as
amended [33 U.S.C. Sec. 1292(2)(A)]. A POTW includes the treatment
works, intercepting sewers, outfall sewers, sewage collection systems,
pumping, power, and other equipment. The POTW is defined at 40 CFR
403.3(o).
Reactor means a device or vessel in which one or more chemicals or
reactants, other than air, are combined or decomposed in such a way that
their molecular structures are altered and one or more new organic
compounds are formed.
Recovery device, as used in the wastewater provisions, means an
individual unit of equipment used for the purpose of recovering
chemicals for fuel value (i.e., net positive heating value), use, reuse,
or for sale for fuel value, use or reuse. Examples of equipment that may
be recovery devices include organic removal devices such as decanters,
strippers, or thin-film evaporation units. To be a recovery device, a
decanter and any other equipment based on the operating principle of
gravity separation must receive only two-phase liquid streams.
Repaired means that equipment is adjusted, or otherwise altered, to
eliminate a leak as defined in the applicable sections of Sec. 63.1255.
Research and development facility means any stationary source whose
primary purpose is to conduct research and development into new
processes and products, where such source is operated under the close
supervision of technically trained personnel, and is not engaged in the
manufacture of products for commercial sale in commerce, except in a de
minimis manner.
Residual means any HAP-containing liquid or solid material that is
removed from a wastewater stream by a waste management unit or treatment
process that does not destroy organics (nondestructive unit). Examples
of residuals from nondestructive waste management units are: the organic
layer and bottom residue removed by a decanter or organic-water
separator and the overheads from a steam stripper or air stripper.
Examples of materials which are not residuals are: silt; mud; leaves;
bottoms from a steam stripper or air stripper; and sludges, ash, or
other materials removed from wastewater being treated by destructive
devices such as biological treatment units and incinerators.
Safety device means a closure device such as a pressure relief
valve, frangible disc, fusible plug, or any other type of device which
functions exclusively to prevent physical damage or permanent
deformation to a unit or its air emission control equipment by venting
gases or vapors directly to the atmosphere during unsafe conditions
resulting from an unplanned, accidental, or emergency event. For the
purposes of this subpart, a safety device is not used for routine
venting of gases or vapors from the vapor headspace underneath a cover
such as during filling of the unit or to adjust the pressure in this
vapor headspace in response to normal daily diurnal ambient temperature
fluctuations. A safety device is designed to remain in a closed position
during normal operations and open only when the internal pressure, or
another relevant parameter, exceeds the device threshold setting
applicable to the air emission control equipment as determined by the
owner or operator based on manufacturer recommendations, applicable
regulations, fire protection and prevention codes, standard engineering
codes and practices, or other requirements for the safe handling of
flammable, combustible, explosive, reactive, or hazardous materials.
Sampling connection system means an assembly of equipment within a
process unit used during periods of representative operation to take
samples of the process fluid. Equipment used to take nonroutine grab
samples is not considered a sampling connection system.
Sensor means a device that measures a physical quantity or the
change in a physical quantity, such as temperature, pressure, flow rate,
pH, or liquid level.
Set pressure means the pressure at which a properly operating
pressure relief device begins to open to relieve atypical process system
operating pressure.
Sewer line means a lateral, trunk line, branch line, or other
conduit including, but not limited to, grates,
[[Page 75]]
trenches, etc., used to convey wastewater streams or residuals to a
downstream waste management unit.
Shutdown means the cessation of operation of a PMPU or an individual
piece of equipment required or used to comply with this part or for
emptying and degassing storage tanks. Shutdown occurs for purposes
including but not limited to: periodic maintenance, replacement of
equipment, or repair. Shutdown does not apply to routine batch
operations or the rinsing or washing of equipment in batch operations
between batches.
Single-seal system means a floating roof having one continuous seal
that completely covers the space between the wall of the storage tank
and the edge of the floating roof. This seal may be a vapor-mounted,
liquid-mounted, or metallic shoe seal.
Small control device means a control device that controls process
vents with total emissions of less than 10 tons of HAP per year, before
control.
Soluble HAP means a HAP listed in Table 3 of this subpart.
Startup means the first time a new or reconstructed source begins
production, or, for new equipment added, including equipment used to
comply with this subpart, the first time the equipment is put into
operation, or for the introduction of a new product/process, the first
time the product or process is run in equipment. As used in
Sec. 63.1255, startup means the setting in operation of a piece of
equipment or a control device that is subject to this subpart.
Storage tank means a tank or other vessel that is used to store
organic liquids that contain one or more HAP as feedstocks or products
of a PMPU. The following are not considered storage tanks for the
purposes of this subpart:
(1) Vessels permanently attached to motor vehicles such as trucks,
railcars, barges, or ships;
(2) Pressure vessels designed to operate in excess of 204.9
kilopascals and without emissions to the atmosphere;
(3) Vessels storing organic liquids that contain HAP only as
impurities;
(4) Wastewater storage tanks; and
(5) Process tanks.
Surface impoundment means a waste management unit which is a natural
topographic depression, manmade excavation, or diked area formed
primarily of earthen materials (although it may be lined with manmade
materials), which is designed to hold an accumulation of liquid wastes
or waste containing free liquids. A surface impoundment is used for the
purpose of treating, storing, or disposing of wastewater or residuals,
and is not an injection well. Examples of surface impoundments are
equalization, settling, and aeration pits, ponds, and lagoons.
Total organic compounds (TOC) means those compounds measured
according to the procedures of Method 18 or Method 25A, 40 CFR part 60,
appendix A.
Treatment process means a specific technique that removes or
destroys the organics in a wastewater or residual stream such as a steam
stripping unit, thin-film evaporation unit, waste incinerator,
biological treatment unit, or any other process applied to wastewater
streams or residuals to comply with Sec. 63.1256. Most treatment
processes are conducted in tanks. Treatment processes are a subset of
waste management units.
Uncontrolled HAP emissions means a gas stream containing HAP which
has exited the process (or process condenser, if any), but which has not
yet been introduced into an air pollution control device to reduce the
mass of HAP in the stream. If the process vent is not routed to an air
pollution control device, uncontrolled emissions are those HAP emissions
released to the atmosphere.
Unit operation means those processing steps that occur within
distinct equipment that are used, among other things, to prepare
reactants, facilitate reactions, separate and purify products, and
recycle materials. Equipment used for these purposes includes but is not
limited to reactors, distillation columns, extraction columns,
absorbers, decanters, dryers, condensers, and filtration equipment.
Vapor-mounted seal means a continuous seal that completely covers
the annular space between the wall, the storage tank or waste management
unit and the edge of the floating roof and is mounted such that there is
a vapor space between the stored liquid and the bottom of the seal.
[[Page 76]]
Volatile organic compounds (VOC) means those materials defined in 40
CFR 51.100.
Waste management unit means the equipment, structure(s),and or
devices used to convey, store, treat, or dispose of wastewater streams
or residuals. Examples of waste management units include wastewater
tanks, air flotation units, surface impoundments, containers, oil-water
or organic-water separators, individual drain systems, biological
wastewater treatment units, waste incinerators, and organic removal
devices such as steam and air stripper units, and thin film evaporation
units. If such equipment is used for recovery then it is part of a
pharmaceutical process and is not a waste management unit.
Wastewater means any portion of an individual wastewater stream or
any aggregation of wastewater streams.
Wastewater stream means water that is discarded from a PMPU through
a single POD, that contains an annual average concentration of partially
soluble and/or soluble HAP compounds of at least 5 parts per million by
weight and a load of at least 0.05 kg/yr, and that is not exempted by
the provisions of Sec. 63.1256(a)(3). For the purposes of this subpart,
noncontact cooling water is not considered a wastewater stream.
Wastewater streams are generated by both process operations and
maintenance activities.
Wastewater tank means a stationary waste management unit that is
designed to contain an accumulation of wastewater or residuals and is
constructed primarily of nonearthen materials (e.g., wood, concrete,
steel, plastic) which provide structural support. Wastewater tanks used
for flow equalization are included in this definition.
Water seal controls means a seal pot, p-leg trap, or other type of
trap filled with water (e.g., flooded sewers that maintain water levels
adequate to prevent air flow through the system) that creates a water
barrier between the sewer line and the atmosphere. The water level of
the seal must be maintained in the vertical leg of a drain in order to
be considered a water seal.
Sec. 63.1252 Standards: General.
Each owner or operator of any affected source subject to the
provisions of this subpart shall control HAP emissions to the level
specified in this section on and after the compliance dates specified in
Sec. 63.1250(f). Compliance with the emission limits may be demonstrated
initially through the provisions of Sec. 63.1257 (Test methods and
compliance procedures) and continuously through the provisions of
Sec. 63.1258 (Monitoring requirements).
(a) Opening of a safety device. Opening of a safety device, as
defined in Sec. 63.1251, is allowed at any time conditions require it to
do so to avoid unsafe conditions.
(b) Closed-vent systems. The owner or operator of a closed-vent
system that contains bypass lines that could divert a vent stream away
from a control device used to comply with the requirements in
Secs. 63.1253, 63.1254, and 63.1256 shall comply with the requirements
of Table 4 to this subpart and paragraph (b)(1) or (2) of this section.
Equipment such as low leg drains, high point bleeds, analyzer vents,
open-ended valves or lines, rupture disks and pressure relief valves
needed for safety purposes are not subject to this paragraph.
(1) Install, calibrate, maintain, and operate a flow indicator that
determines whether vent stream flow is present at least once every 15
minutes. Records shall be maintained as specified in
Sec. 63.1259(i)(6)(i). The flow indicator shall be installed at the
entrance to any bypass line that could divert the vent stream away from
the control device to the atmosphere; or
(2) Secure the bypass line valve in the closed position with a car
seal or lock and key type configuration. A visual inspection of the seal
or closure mechanism shall be performed at least once every month to
ensure that the valve is maintained in the closed position and the vent
stream is not diverted through the bypass line. Records shall be
maintained as specified in Sec. 63.1259(i)(6)(ii).
(c) Heat exchange systems. Except as provided in paragraph (c)(2) of
this section, owners and operators of affected sources shall comply with

practice (CGMP) requirements of 21 CFR part 211 may elect to use the
physical integrity of the reactor as the surrogate indicator of heat
exchange system leaks around the reactor.
(d) Emissions averaging provisions. Except as specified in
paragraphs (d)(1) through (5) of this section, owners or operators of
storage tanks or processes subject to the provisions of Secs. 63.1253
and 63.1254 may choose to comply by using emissions averaging
requirements specified in Sec. 63.1257(g) or (h) for any storage tank or
process.
(1) A State may prohibit averaging of HAP emissions and require the
owner or operator of an existing source to comply with the provisions in
Secs. 63.1253 and 63.1254.
(2) Only emission sources subject to the requirements of
Sec. 63.1253(b)(1) and (c)(1) or Sec. 63.1254(a)(2), (a)(3)(ii)(A) or
(a)(3)(iii) may be included in any averaging group.
(3) Processes which have been permanently shutdown or storage tanks
permanently taken out of HAP service may not be included in any
averaging group.
(4) Processes and storage tanks already controlled on or before
November 15, 1990 may not be included in an emissions averaging group,
except where the level of control is increased after November 15, 1990.
In these cases, the uncontrolled emissions shall be the controlled
emissions as calculated on November 15, 1990 for the purpose of
determining the uncontrolled emissions as specified in Sec. 63.1257(g)
and (h).
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart may not be included in an emission
averaging group, unless the level of control has been increased after
November 15, 1990 above what is required by the other State or Federal
rule. Only the control above what is required by the other State or
Federal rule will be credited. However, if an emission point has been
used to generate emissions averaging credit in an approved emissions
average, and the point is subsequently made subject to a State or
Federal rule other than this subpart, the point can continue to generate
emissions averaging credit for the purpose of complying with the
previously approved average.
(6) Not more than 20 processes subject to Sec. 63.1254(a)(2)(i), 20
storage tanks subject to Sec. 63.1253(b)(1), and 20 storage tanks
subject to Sec. 63.1253(c)(1)(i) at an affected source may be included
in an emissions averaging group.
(7) Compliance with the emissions standards in Sec. 63.1253 shall be
satisfied when the annual percent reduction efficiency is greater than
or equal to 90 percent for those tanks meeting the requirements of
Sec. 63.1253(a)(1) and 95 percent for those tanks meeting the
requirements of Sec. 63.1253(a)(2), as demonstrated using the test
methods and compliance procedures specified in Sec. 63.1257(g).
(8) Compliance with the emissions standards in Sec. 63.1254(a)(2)
shall be satisfied when the annual percent reduction efficiency is
greater than or equal to 93 percent, as demonstrated using the test
methods and compliance procedures specified in Sec. 63.1257(h).
(e) Pollution prevention alternative. Except as provided in
paragraph (e)(1) of this section, owners and operators may choose to
meet the pollution prevention alternative requirement specified in
either paragraph (e)(2) or (3) of this section for any PMPU, in lieu of
the requirements specified in Secs. 63.1253, 63.1254, 63.1255, and
63.1256. Compliance with paragraphs (e)(2) and (3) of this section shall
be demonstrated through the procedures in Sec. 63.1257(f).
(1) The HAP that are generated in the PMPU that are not part of the
production-indexed consumption factor must be controlled according to
the requirements of Secs. 63.1253, 63.1254, 63.1255, and 63.1256. The
HAP that are generated as a result of combustion control of emissions
must be controlled according to the requirements of paragraph (g) of
this section.
(2) The production-indexed HAP consumption factor (kg HAP consumed/
kg
[[Page 78]]
produced) shall be reduced by at least 75 percent from a 3 year average
baseline established no earlier than the 1987 calendar year, or for the
time period from startup of the process until the present in which the
PMPU was operational and data are available, whichever is the lesser
time period. If a time period less than 3 years is used to set the
baseline, the data must represent at least 1 year's worth of data. For
any reduction in the HAP factor achieved by reducing a HAP that is also
a VOC, an equivalent reduction in the VOC factor is also required. For
any reduction in the HAP factor that is achieved by reducing a HAP that
is not a VOC, the VOC factor may not be increased.
(3) Both requirements specified in paragraphs (e)(3)(i) and (ii) of
this section are met.
(i) The production-indexed HAP consumption factor (kg HAP consumed/
kg produced) shall be reduced by at least 50 percent from a 3-year
average baseline established no earlier than the 1987 calendar year, or
for the time period from startup of the process until the present in
which the PMPU was operational and data are available, whichever is
less. If a time period less than 3 years is used to set the baseline,
the data must represent at least 1 year's worth of data. For any
reduction in the HAP factor achieved by reducing a HAP that is also a
VOC, an equivalent reduction in the VOC factor is also required. For any
reduction in the HAP factor that is achieved by reducing a HAP that is
not a VOC, the VOC factor may not be increased.
(ii) The total PMPU HAP emissions shall be reduced by an amount, in
kg/yr, that, when divided by the annual production rate, in kg/yr, and
added to the reduction of the production-indexed HAP consumption factor,
in kg/kg, yields a value of at least 75 percent of the average baseline
HAP production-indexed consumption factor established according to
paragraph (e)(3)(i) of this section according to the equation provided
in Sec. 63.1257(f)(2)(ii)(A). The total PMPU VOC emissions shall be
reduced by an amount calculated according to the equation provided in
Sec. 63.1257(f)(2)(ii)(B). The annual reduction in HAP and VOC air
emissions must be due to the use of the following control devices:
(A) Combustion control devices such as incinerators, flares or
process heaters.
(B) Control devices such as condensers and carbon adsorbers whose
recovered product is destroyed or shipped offsite for destruction.
(C) Any control device that does not ultimately allow for recycling
of material back to the PMPU.
(D) Any control device for which the owner or operator can
demonstrate that the use of the device in controlling HAP emissions will
have no effect on the production-indexed consumption factor for the
PMPU.
(f) Control requirements for certain liquid streams in open systems
within a PMPU. (1) The owner or operator shall comply with the
provisions of Table 5 of this subpart, for each item of equipment

concentration greater than or equal to 5,200 ppmw of partially soluble
and/or soluble HAP compounds. The annual average concentration shall be
determined according to the procedures in Sec. 63.1257(e)(1)(ii).
(ii) Is a tank that receives one or more streams that contain water
with an annual average concentration greater than or equal to 1,300 ppmw

HAP compounds. The owner or operator of the source shall determine the
average concentration of the stream at the inlet to the tank and
according to the procedures in Sec. 63.1257(e)(1)(ii).
(g) Control requirements for halogenated vent streams that are
controlled by combustion devices. If a combustion device is used to
comply with the provisions of Secs. 63.1253 (storage tanks), 63.1254
(process vents), 63.1256(h) (wastewater vent streams) for a halogenated
vent stream, then the vent stream shall be ducted to a halogen reduction
device such as, but not limited to, a scrubber, before it is discharged
to the atmosphere. The halogen reduction device must reduce emissions by
the amounts specified in either paragraph (g)(1) or (2) of this section.
(1) A halogen reduction device after the combustion control device

Where:
FRa = flow-weighted average flowrate for the vent, scfm
Di = duration of each emission event, min
FRi = flowrate of each emission event, scfm
n = number of emission events
FR = flowrate, scfm
HL = annual uncontrolled HAP emissions, lb/yr, as defined in
Sec. 63.1251
(B) As an alternative to the criteria described in paragraph

paragraph (a)(3)(i) of this section on or before April 2, 1997, was
designed to reduce uncontrolled HAP emissions of total HAP by greater
than or equal to 93 percent by weight, but less than 98 percent by
weight, then the control device is required to be operated to reduce
inlet emissions of total HAP by 93 percent by weight or greater.
(b) New sources. Uncontrolled HAP emissions from the sum of all
process vents within a process at a new affected source that are not
controlled according to any of the requirements of paragraphs (b)(1),

routing all vents from a process to a control device achieving an outlet
TOC concentration, as calibrated on methane or the predominant HAP, of
20 ppmv or less, and an outlet concentration of hydrogen halides and
halogens of 20 ppmv or less. Any process vents within a process that are
not routed to this control device must be controlled in accordance with
the provisions of paragraphs (a)(2),(a)(3), and (b) of this section, as
applicable. Compliance with the outlet concentrations shall be
determined by the initial compliance procedures described in
Sec. 63.1257(d)(1)(iv)
[[Page 82]]
and the continuous emission monitoring requirements described in
Sec. 63.1258(b)(5).

plant site as a process subject to the provisions of this subpart.
(7) Each piece of equipment to which this section applies shall be
identified such that it can be distinguished readily from equipment that
is not subject to this section. Identification of the equipment does not
require physical tagging of the equipment. For example, the equipment
may be identified on a plant site plan, in log entries, or by
designation of process boundaries by some form of weatherproof
identification. If changes are made to the affected source subject to
the leak detection requirements, equipment identification for each type
of component shall be updated, if needed, within 15 calendar days of the
end of each monitoring period for that component.
(8) Equipment that is in vacuum service is excluded from the
requirements of this section.
(9) Equipment that is in organic HAP service, but is in such service
less than 300 hours per calendar year, is excluded from the requirements
of this section if it is identified as required in paragraph (g)(9) of
this section.
(10) When each leak is detected by visual, audible, or olfactory
means, or by monitoring as described in Sec. 63.180(b) or (c), the
following requirements apply:
(i) A weatherproof and readily visible identification, marked with
the equipment identification number, shall be attached to the leaking
equipment.
(ii) The identification on a valve or connector in light liquid or
gas/vapor service may be removed after it has been monitored as
specified in paragraph (e)(7)(iii) of this section and Sec. 63.174(e),

of paragraphs (b)(1)(vii)(C) or (D) of this section after a monitoring
period in which less than 0.5 percent of the connectors are determined
to be leaking.
(F) Section 63.174(b)(3)(iii) shall not apply. Instead, monitoring
shall be required once every 8 years, if the percent leaking connectors
in the process unit was less than 0.25 percent during the last required
monitoring period. An owner or operator shall monitor at least 50
percent of the connectors in the first 4 years and the remainder of the
connectors within the next 4 years. If the percent leaking connectors in
the first 4 years is equal to or greater than 0.35 percent, the
monitoring program shall revert at that time to the appropriate
monitoring frequency specified in paragraphs (b)(1)(vii)(C), (D), or (E)
of this section.
(viii) Section 63.177, Alternative means of emission limitation:

below:
(i) For a group of processes with 2 percent or greater leaking
valves, calculated according to paragraph (e)(6) of this section, the
owner or operator shall monitor each valve once per month, except as
specified in paragraph (e)(9) of this section.
(ii) For a group of processes with less than 2 percent leaking
valves, the owner or operator shall monitor each valve once each
quarter, except as provided in paragraphs (e)(4)(iii) through (e)(4)(v)
of this section.
(iii) For a group of processes with less than 1 percent leaking
valves, the owner or operator may elect to monitor each valve once every
2 quarters.
(iv) For a group of processes with less than 0.5 percent leaking
valves, the owner or operator may elect to monitor each valve once every
4 quarters.
(v) For a group of processes with less than 0.25 percent leaking
valves, the owner or operator may elect to monitor each valve once every
2 years.
(5) Calculation of percent leakers. For a group of processes to
which this subpart applies, an owner or operator may
[[Page 87]]
choose to subdivide the valves in the applicable group of processes and
apply the provisions of paragraph (e)(4) of this section to each
subgroup. If the owner or operator elects to subdivide the valves in the
applicable group of processes, then the provisions of paragraphs
(e)(5)(i) through (e)(5)(viii) of this section apply.
(i) The overall performance of total valves in the applicable group
of processes must be less than 2 percent leaking valves, as detected
according to paragraphs (e)(3) (i) and (ii) of this section and as
calculated according to paragraphs (e)(6) (ii) and (iii) of this
section.
(ii) The initial assignment or subsequent reassignment of valves to
subgroups shall be governed by the provisions of paragraphs (e)(5)(ii)
(A) through (C) of this section.
(A) The owner or operator shall determine which valves are assigned
to each subgroup. Valves with less than 1 year of monitoring data or
valves not monitored within the last 12 months must be placed initially
into the most frequently monitored subgroup until at least 1 year of
monitoring data has been obtained.
(B) Any valve or group of valves can be reassigned from a less
frequently monitored subgroup to a more frequently monitored subgroup
provided that the valves to be reassigned were monitored during the most
recent monitoring period for the less frequently monitored subgroup. The
monitoring results must be included with the less frequently monitored
subgroup's monitoring event and associated next percent leaking valves
calculation for that group.
(C) Any valve or group of valves can be reassigned from a more
frequently monitored subgroup to a less frequently monitored subgroup
provided that the valves to be reassigned have not leaked for the period
of the less frequently monitored subgroup (e.g., for the last 12 months,
if the valve or group of valves is to be reassigned to a subgroup being
monitored annually). Nonrepairable valves may not be reassigned to a
less frequently monitored subgroup.
(iii) The owner or operator shall determine every 6 months if the
overall performance of total valves in the applicable group of processes
is less than 2 percent leaking valves and so indicate the performance in
the next periodic report. If the overall performance of total valves in
the applicable group of processes is 2 percent leaking valves or
greater, the owner or operator shall revert to the program required in
paragraphs (e)(2) through (e)(4) of this section. The overall
performance of total valves in the applicable group of processes shall
be calculated as a weighted average of the percent leaking valves of
each subgroup according to the following Equation 4:
[GRAPHIC] [TIFF OMITTED] TR21SE98.002
where:
%VLO = overall performance of total valves in the applicable
process or group of processes
%VLi = percent leaking valves in subgroup I, most recent
value calculated according to the procedures in paragraphs (e)(6) (ii)
and (iii) of this section
Vi = number of valves in subgroup I
n = number of subgroups
(iv) Records. In addition to records required by paragraph (g) of
this section, the owner or operator shall maintain records specified in
paragraphs (e)(5)(iv)(A) through (D) of this section.
(A) Which valves are assigned to each subgroup,

shall be treated as if it were a process for the purposes of applying
the provisions of this section.
(6)(i) The owner or operator shall decide no later than the
implementation date of this subpart or upon revision of an operating
permit how to group the processes. Once the owner or operator has
decided, all subsequent percentage calculations shall be made on the
same basis.
(ii) Percent leaking valves for each group of processes or subgroup
shall be determined by the following Equation 5:
%VL = [VL/VT] x 100 (Eq. 5)
Where:
%VL = percent leaking valves
VL = number of valves found leaking excluding nonrepairables
as provided in paragraph (e)(6)(iv)(A) of this section
VT = total valves monitored, in a monitoring period excluding
valves monitored as required by (e)(7)(iii) of this section
(iii) When determining monitoring frequency for each group of
processes or subgroup subject to monthly, quarterly, or semiannual
monitoring frequencies, the percent leaking valves shall be the
arithmetic average of the percent leaking valves from the last two
monitoring periods. When determining monitoring frequency for each group
of processes or subgroup subject to annual or biennial (once every 2
years) monitoring frequencies, the percent leaking valves shall be the
arithmetic average of the percent leaking valves from the last three
monitoring periods.
(iv)(A) Nonrepairable valves shall be included in the calculation of
percent leaking valves the first time the valve is identified as leaking
and nonrepairable and as required to comply with paragraph (e)(6)(iv)(B)
of this section. Otherwise, a number of nonrepairable valves (identified
and included in the percent leaking calculation in a previous period) up
to a maximum of 1 percent of the total number of valves in organic HAP
service at a process may be excluded from calculation of percent leaking
valves for subsequent monitoring periods.
(B) If the number of nonrepairable valves exceeds 1 percent of the
total number of valves in organic HAP service at a process, the number
of nonrepairable valves exceeding 1 percent of the total number of
valves in organic HAP service shall be included in the calculation of
percent leaking valves.
(7) Repair provisions. (i) When a leak is detected, it shall be
repaired as soon as practicable, but no later than 15 calendar days
after the leak is detected, except as provided in paragraph (b)(1)(v) of

calendar days after each leak is detected.
(iii) When a leak is repaired, the valve shall be monitored at least
once within the first 3 months after its repair. Days that the valve is
not in organic HAP service shall not be considered part of this 3 month
period.
(8) First attempts at repair include, but are not limited to, the
following practices where practicable:
(i) Tightening of bonnet bolts,
(ii) Replacement of bonnet bolts,
(iii) Tightening of packing gland nuts, and
(iv) Injection of lubricant into lubricated packing.
(9) Any equipment located at a plant site with fewer than 250 valves
in organic HAP service in the affected source is exempt from the
requirements for monthly monitoring specified in paragraph (e)(4)(i) of
this section. Instead, the owner or operator shall monitor each valve in
organic
[[Page 89]]
HAP service for leaks once each quarter, or comply with paragraphs
(e)(4)(iii) or (e)(4)(iv) of this section.

Sec. 63.1256 Standards: Wastewater.
(a) General. Each owner or operator of any affected source (existing
or new) shall comply with the general wastewater requirements in
paragraphs (a)(1) and (2) of this section.
(1) Identify wastewater that requires control. For each POD, the
owner or operator shall comply with the requirements in either paragraph
(a)(1)(i), or (ii) of this section to determine whether a wastewater
stream is an affected wastewater stream that requires control for
soluble and/or partially soluble HAP compounds or to designate the
wastewater stream as an affected wastewater stream, respectively. The
owner or operator may use a combination of the approaches in paragraphs
(a)(1)(i) and (ii) of this section for different affected wastewater
generated at the source. The owner or operator shall also comply with
the requirements for multiphase discharges in paragraph (a)(4) of this
section. Wastewater identified in paragraph (a)(3) of this section is
exempt from the provisions of this subpart.
(i) Determine characteristics of a wastewater stream. At new and
existing sources, a wastewater stream is an affected wastewater stream
if the annual average concentration and annual load exceed any of the
criteria specified in paragraph (a)(1)(i)(A) through (C) of this
section. At new sources, a wastewater stream is subject to additional
[[Page 95]]
control requirements if the annual average concentration and annual load
exceed the criteria specified in paragraphs (a)(1)(i)(D) of this
section. The owner or operator shall comply with the provisions of
Sec. 63.1257(e)(1) to determine the annual average concentrations and
annual load of partially soluble and soluble HAP compounds.
(A) The wastewater stream contains partially soluble HAP compounds
at an annual average concentration greater than 1,300 ppmw, and the
total soluble and partially soluble HAP load in all wastewater from the
PMPU exceeds 1 Mg/yr.
(B) The wastewater stream contains partially soluble and/or soluble
HAP compounds at an annual average concentration of 5,200 ppmw, and the
total soluble and partially soluble HAP load in all wastewater from the
PMPU exceeds 1 Mg/yr.
(C) The wastewater stream contains partially soluble and/or soluble
HAP at an annual average concentration of greater than 10,000 ppmw, and
the total partially soluble and/or soluble HAP load in all wastewater
from the affected source is greater than 1 Mg/yr.
(D) The wastewater stream contains soluble HAP compounds at an
annual average concentration greater than 110,000 ppmw, and the total
soluble and partially soluble HAP load in all wastewater from the PMPU
exceeds 1 Mg/yr.
(ii) Designate wastewater as affected wastewater. For existing
sources, the owner or operator may elect to designate wastewater streams
as meeting the criteria of either paragraphs (a)(1)(i)(A),(B), or (C) of
this section. For new sources, the owner or operator may elect to
designate wastewater streams meeting the criterion in paragraph
(a)(1)(i)(D) or for wastewater known to contain no soluble HAP, as
meeting the criterion in paragraph (a)(1)(i)(A) of this section. For
designated wastewater the procedures specified in paragraphs
(a)(1)(ii)(A) and (B) of this section shall be followed, except as
specified in paragraphs (g)(8)(i), (g)(9)(i), and (g)(10) of this
section. The owner or operator is not required to determine the annual
average concentration or load for each designated wastewater stream for
the purposes of this section.
(A) From the POD for the wastewater stream that is designated as an

of this section are required to demonstrate initial compliance with
Secs. 63.1253, 63.1254, 63.1256, and 63.1252(e), respectively. The
provisions in paragraphs (a) (2) through (3) apply to performance tests
that are specified in paragraphs (c), (d), and (e) of this section. The
provisions in paragraph (a)(5) of this section are used to demonstrate
initial compliance with the alternative standards specified in
Secs. 63.1253(d) and 63.1254(c). The provisions in paragraph (a)(6) of
this section are used to comply with the outlet concentration
requirements specified in Secs. 63.1253(c), 63.1254 (a)(2)(i) and
(a)(3)(ii)(B), 63.1254(b)(i) and 63.1256(h)(2).
(1) Design evaluation. To demonstrate that a control device meets
the required control efficiency, a design evaluation must address the
composition and organic HAP concentration of the vent stream entering
the control device. A design evaluation also must address other vent
stream characteristics and control device operating parameters as
specified in any one of paragraphs (a)(1) (i) through (vi) of this
section, depending on the type of control device that is used. If the
vent stream is not the only inlet to the control device, the efficiency
demonstration also must consider all other vapors, gases, and liquids,
other than fuels, received by the control device.
(i) For an enclosed combustion device used to comply with the
provisions of 63.1253 (b)(2) or (c)(2), or 63.1256(h)(2)(i)(C) with a
minimum residence time of 0.5 seconds and a minimum temperature of
760 deg.C, the design evaluation must document that these conditions
exist.
(ii) For a combustion control device that does not satisfy the
criteria in paragraph (a)(1)(i) of this section, the design evaluation
must document control efficiency and address the following
characteristics, depending on the type of control device:
(A) For a thermal vapor incinerator, the design evaluation must
consider the autoignition temperature of the organic HAP, must consider
the vent stream flow rate, and must establish the design minimum and
average temperature in the combustion zone and the combustion zone
residence time.
[[Page 110]]
(B) For a catalytic vapor incinerator, the design evaluation shall
consider the vent stream flow rate and shall establish the design
minimum and average temperatures across the catalyst bed inlet and
outlet.
(C) For a boiler or process heater, the design evaluation shall
consider the vent stream flow rate; shall establish the design minimum
and average flame zone temperatures and combustion zone residence time;
and shall describe the method and location where the vent stream is
introduced into the flame zone.
(iii) For a condenser, the design evaluation shall consider the vent
stream flow rate, relative humidity, and temperature and shall establish
the design outlet organic HAP compound concentration level, design
average temperature of the condenser exhaust vent stream, and the design
average temperatures of the coolant fluid at the condenser inlet and
outlet. The temperature of the gas stream exiting the condenser must be
measured and used to establish the outlet organic HAP concentration.
(iv) For a carbon adsorption system that regenerates the carbon bed
directly onsite in the control device such as a fixed-bed adsorber, the
design evaluation shall consider the vent stream flow rate, relative
humidity, and temperature and shall establish the design exhaust vent
stream organic compound concentration level, adsorption cycle time,
number and capacity of carbon beds, type and working capacity of
activated carbon used for carbon beds, design total regeneration stream
mass or volumetric flow over the period of each complete carbon bed
regeneration cycle, design carbon bed temperature after regeneration,
design carbon bed regeneration time, and design service life of carbon.
For vacuum desorption, the pressure drop shall be included.
(v) For a carbon adsorption system that does not regenerate the
carbon bed directly onsite in the control device such as a carbon
canister, the design evaluation shall consider the vent stream mass or
volumetric flow rate, relative humidity, and temperature and shall
establish the design exhaust vent stream organic compound concentration
level, capacity of carbon bed, type and working capacity of activated
carbon used for carbon bed, and design carbon replacement interval based
on the total carbon working capacity of the control device and source
operating schedule.
(vi) For a scrubber, the design evaluation shall consider the vent
stream composition; constituent concentrations; liquid-to-vapor ratio;
scrubbing liquid flow rate and concentration; temperature; and the
reaction kinetics of the constituents with the scrubbing liquid. The
design evaluation shall establish the design exhaust vent stream organic
compound concentration level and will include the additional information
in paragraphs (a)(1)(vi)(A) and (B) of this section for trays and a
packed column scrubber.
(A) Type and total number of theoretical and actual trays;
(B) Type and total surface area of packing for entire column, and
for individual packed sections if column contains more than one packed
section.
(2) Calculation of TOC or total organic HAP concentration. The TOC
concentration or total organic HAP concentration is the sum of the
concentrations of the individual components. If compliance is being
determined based on TOC, the owner or operator shall compute TOC for
each run using Equation 6 of this subpart. If compliance with the
wastewater provisions is being determined based on total organic HAP,

Administrator for approval prior to testing in accordance with
Sec. 63.7(c) and Sec. 63.1260(l). The test plan shall include the

(A) Absolute worst-case conditions are defined by the criteria
presented in paragraph (b)(8)(i)(A)(1) or (2) of this section if the

Otherwise, absolute worst-case conditions are defined by the conditions
in paragraph (b)(8)(i)(A)(3) of this section.
(1) The period in which the inlet to the control device will contain
at least 50 percent of the maximum HAP load (in lb) capable of being
vented to the control device over any 8 hour period. An emission profile
as described in paragraph (b)(8)(ii)(A) of this section
[[Page 113]]
shall be used to identify the 8-hour period that includes the maximum
projected HAP load.
(2) A 1-hour period of time in which the inlet to the control device
will contain the highest HAP mass loading rate, in lb/hr, capable of
being vented to the control device. An emission profile as described in
paragraph (b)(8)(ii)(A) of this section shall be used to identify the 1-
hour period of maximum HAP loading.
(3) The period of time when the HAP loading or stream composition
(including non-HAP) is most challenging for the control device. These
conditions include, but are not limited to the following:
(i) Periods when the stream contains the highest combined VOC and
HAP load, in lb/hr, described by the emission profiles in (b)(8)(ii);
(ii) Periods when the streams contain HAP constituents that approach
limits of solubility for scrubbing media;
(iii) Periods when the streams contain HAP constituents that
approach limits of adsorptivity for carbon adsorption systems.
(B) Hypothetical worst-case conditions are simulated test conditions
that, at a minimum, contain the highest hourly HAP load of emissions
that would be predicted to be vented to the control device from the
emissions profile described in paragraph (b)(8)(ii)(B) or (C) of this
section.
(ii) Emissions profile. The owner or operator may choose to perform
tests only during those periods of the worst-case conditions that the
owner or operator selects to control as part of achieving the required
emission reduction. The owner or operator must develop an emission
profile for the vent to the control device that describes the
characteristics of the vent stream at the inlet to the control device
under worst case conditions. The emission profile shall be developed
based on any one of the procedures described in (b)(8)(ii)(A) through
(C) of this section, as required by paragraph (b)(8)(i).
(A) Emission profile by process. The emission profile must consider
all emission episodes that could contribute to the vent stack for a
period of time that is sufficient to include all processes venting to
the stack and shall consider production scheduling. The profile shall
describe the HAP load to the device that equals the highest sum of
emissions from the episodes that can vent to the control device in any
given hour. Emissions per episode shall be calculated using the
procedures specified in paragraph (d)(2) of this section. Emissions per
episode shall be divided by the duration of the episode only if the
duration of the episode is longer than 1 hour.
(B) Emission profile by equipment. The emission profile must consist
of emissions that meet or exceed the highest emissions, in lb/hr, that
would be expected under actual processing conditions. The profile shall
describe equipment configurations used to generate the emission events,
volatility of materials processed in the equipment, and the rationale
used to identify and characterize the emission events. The emissions may
be based on using a compound more volatile than compounds actually used
in the process(es), and the emissions may be generated from all
equipment in the process(es) or only selected equipment.
(C) Emission profile by capture and control device limitation. The
emission profile shall consider the capture and control system
limitations and the highest emissions, in lb/hr, that can be routed to
the control device, based on maximum flowrate and concentrations
possible because of limitations on conveyance and control equipment
(e.g., fans, LEL alarms and safety bypasses).
(iii) Three runs, at a minimum of 1 hour each and a maximum of 8
hours each, are required for performance testing. Each run must occur
over the same worst-case conditions, as defined in paragraph (b)(8)(i)
of this section.

evaluation nor a performance test is required. For any other
nonbiological treatment process, the owner or operator shall conduct
either a design evaluation as specified in paragraph (e)(2)(ii) of this
section, or a performance test as specified in paragraph (e)(2)(iii) of
this section to demonstrate that each nonbiological treatment process
used to comply with Sec. 63.1256(g) (8), (9), and/or (12) achieves the
conditions specified for compliance. The owner or operator shall
demonstrate by the procedures in either paragraph (e)(2) (ii) or (iii)
of this section that each closed biological treatment process used to
comply with Sec. 63.1256 (g)(8)(ii), (g)(9)(ii), (g)(11), or (g)(12)
achieves the conditions specified for compliance. If an open biological
treatment unit is used to comply with Sec. 63.1256 (g)(8)(ii),

percent reduction from removal/destruction in the treatment unit and
control device shall be determined by a mass balance over the unit. The
mass flow rate of soluble and/or partially soluble HAP compounds exiting
the treatment process shall be the sum of the mass flow rate of soluble
and/or partially soluble HAP compounds in the wastewater stream exiting
the biological treatment process and the mass flow rate of the vented
gas stream exiting the control device. The mass flow rate entering the
treatment process minus the mass flow rate exiting the process
determines the actual mass removal. Compounds that meet the requirements
specified in paragraph (e)(2)(iii)(A)(4) of this section are not
required to be included in the design evaluation; the term ``performance
test'' in paragraph (e)(2)(iii)(A)(4) of this section shall mean

Performance tests shall be conducted when the treatment process is
operating at a representative inlet flow rate and concentration. If the
treatment process will be operating at several different sets of
representative operating conditions, the owner or operator shall comply
with paragraphs (e)(2)(iii)(A)(2)(i) and (ii) of this section. The owner
or operator shall record information that is necessary to document
treatment process or control device operating conditions during the
test.

operated at several different sets of representative operating
conditions, performance testing over the entire range is not required.
In such cases, the performance test results shall be supplemented with
modeling and/or engineering assessments to demonstrate performance over
the operating range.
[[Page 130]]
(ii) Consideration of residence time. If concentration and/or flow
rate to the treatment process are not relatively constant (i.e.,
comparison of inlet and outlet data will not be representative of
performance), the owner or operator shall consider residence time, when
determining concentration and flow rate.
(3) Testing equipment. All testing equipment shall be prepared and
installed as specified in the applicable test methods, or as approved by
the Administrator.
(4) Compounds not required to be considered in performance tests.
Compounds that meet the requirements specified in (e)(2)(iii)(A)(4)(i),
(ii), or (iii) of this section are not required to be included in the
performance test. Concentration measurements based on Method 305 shall
be adjusted by dividing each concentration by the compound-specific Fm
factor listed in Table 8 of this subpart. Concentration measurements
based on methods other than Method 305 shall not be adjusted by the
compound-specific Fm factor listed in Table 8 of this subpart.
(i) Compounds not used or produced by the PMPU; or
(ii) Compounds with concentrations at the POD that are below 1 ppmw;
or
(iii) Compounds with concentrations at the POD that are below the
lower detection limit where the lower detection limit is greater than 1
ppmw. The method shall be an analytical method for wastewater which has
the compound of interest as a target analyte.
(5) Treatment using a series of treatment processes. In all cases
where the wastewater provisions in this subpart allow or require the use
of a treatment process to comply with emissions limitations, the owner
or operator may use multiple treatment processes. The owner or operator
complying with the requirements of Sec. 63.1256(g)(7)(i), when
wastewater is conveyed by hard-piping, shall comply with either
paragraph (e)(2)(iii)(A)(5)(i) or (ii) of this section. The owner or
operator complying with the requirements of Sec. 63.1256(g)(7)(ii) shall
comply with the requirements of paragraph (e)(2)(iii)(A)(5)(ii) of this
section.
(i) The owner or operator shall conduct the performance test across
each series of treatment processes. For each series of treatment
processes, inlet concentration and flow rate shall be measured either
where the wastewater enters the first treatment process in a series of
treatment processes, or prior to the first treatment process as
specified in paragraph (e)(2)(iii)(A)(6) of this section. For each
series of treatment processes, outlet concentration and flow rate shall
be measured where the wastewater exits the last treatment process in the
series of treatment processes, except when the last treatment process is
an open or a closed aerobic biological treatment process demonstrating
compliance by using the procedures in paragraphs (e)(2)(iii)(E) or (F)
of this section. When the last treatment process is either an open or a
closed aerobic biological treatment process demonstrating compliance by
using the procedures in paragraphs (e)(2)(iii)(E) or (F) of this
section, inlet and outlet concentrations and flow rates shall be
measured at the inlet and outlet to the series of treatment processes
prior to the biological treatment process and at the inlet to the
biological treatment process, except as provided in paragraph
(e)(2)(iii)(A)(6)(ii) of this section. The mass flow rate destroyed in
the biological treatment process for which compliance is demonstrated
using paragraph (e)(2)(iii)(E) or (F) of this section shall be added to
the mass flow rate removed or destroyed in the series of treatment units
before the biological treatment unit. This sum shall be used to
calculate the overall control efficiency.
(ii) The owner or operator shall conduct the performance test across
each treatment process in the series of treatment processes. The mass
flow rate removed or destroyed by each treatment process shall be added
together and the overall control efficiency calculated to determine
whether compliance has been demonstrated using paragraphs
(e)(2)(iii)(C), (D), (E), (F), or (G) of this section, as applicable. If
a biological treatment process is one of the treatment processes in the
series of treatment processes, the inlet to the biological treatment
process shall be the point at which the wastewater enters the biological
treatment process, or the inlet to the equalization tank if
[[Page 131]]
all the criteria of paragraph (e)(2)(iii)(A)(6)(ii) of this section are
met.
(6) The owner or operator determining the inlet for purposes of
demonstrating compliance with paragraph (e)(2)(iii)(E), or (F)of this
section may elect to comply with paragraph (e)(2)(iii)(A)(6)(i) or (ii)
of this section.
(i) When wastewater is conveyed exclusively by hard-piping from the
point of determination to a treatment process that is either the only
treatment process or the first in a series of treatment processes (i.e.,
no treatment processes or other waste management units are used upstream
of this treatment process to store, handle, or convey the wastewater),
the inlet to the treatment process shall be at any location from the
point of determination to where the wastewater stream enters the
treatment process. When samples are taken upstream of the treatment
process and before wastewater streams have converged, the owner or
operator shall ensure that the mass flow rate of all affected wastewater
is accounted for when using Sec. 63.1256(g)(8)(ii), (g)(9)(ii) or
(g)(12) of this subpart to comply and that the mass flow rate of all
wastewater, not just affected wastewater, is accounted for when using
Sec. 63.1256(g)(11) to comply, except as provided in paragraph
(e)(2)(iii)(A)(4) of this section.
(ii) The owner or operator may consider the inlet to the
equalization tank as the inlet to the biological treatment process if
the wastewater is conveyed by hard-piping from either the last previous
treatment process or the point of determination to the equalization
tank; or the wastewater is conveyed from the equalization tank
exclusively by hard-piping to the biological treatment process and no
treatment processes or other waste management units are used to store,
handle, or convey the wastewater between the equalization tank and the
biological treatment process; or the equalization tank is equipped with
a fixed roof and a closed-vent system that routes emissions to a control
device that meets the requirements of Sec. 63.1256(b)(1)(i) through (iv)
and Sec. 63.1256(b)(2)(i). The outlet from the series of treatment
processes prior to the biological treatment process is the point at
which the wastewater exits the last treatment process in the series
prior to the equalization tank, if the equalization tank and biological
treatment process are part of a series of treatment processes. The owner
or operator shall ensure that the mass flow rate of all affected
wastewater is accounted for when using Sec. 63.1256(g)(9)(ii) or (12) to
comply and that the mass flow rate of all wastewater, not just affected
wastewater is accounted for when using Sec. 63.1256(g)(11) to comply,
except as provided in paragraph (e)(2)(iii)(A)(4) of this section.
(B) Noncombustion treatment process--concentration limits. This
paragraph applies to performance tests that are conducted to demonstrate
compliance of a noncombustion treatment process with the ppmw wastewater
stream concentration limits at the outlet of the treatment process. This
compliance option is specified in Sec. 63.1256(g)(8)(i) and (9)(i).
Wastewater samples shall be collected using sampling procedures which
minimize loss of organic compounds during sample collection and analysis
and maintain sample integrity per paragraph (b)(10)(iii) of this
section. Samples shall be collected and analyzed using the procedures
specified in paragraphs (b)(10)(i), (ii), and (iii) of this section.
Samples may be grab samples or composite samples. Samples shall be taken
at approximately equally spaced time intervals over a 1-hour period.
Each 1-hour period constitutes a run, and the performance test shall
consist of a minimum of three runs. Concentration measurements based on
methods other than Method 305 may be adjusted by multiplying each
concentration by the compound-specific Fm factor listed in Table 8 of
this subpart. (For affected wastewater streams that contains both
partially soluble and soluble HAP compounds, compliance is demonstrated
only if the sum of the concentrations of partially soluble HAP compounds
is less than 50 ppmw, and the sum of the concentrations of soluble HAP
compounds is less than 520 ppmw.)

removal/destruction option. This paragraph applies to performance tests
that are conducted to demonstrate compliance of a
[[Page 132]]
noncombustion, nonbiological treatment process with the percent mass
removal limits specified in Sec. 63.1256(g)(8)(ii) and (9)(ii) for

listed in Table 8 of this subpart.
(2) Flow rate. The flow rate of the entering and exiting wastewater
streams shall be determined using inlet and outlet flow meters,
respectively. Where the outlet flow is not greater than the inlet flow,
a single flow meter may be used, and may be used at either the inlet or
outlet. Flow rate measurements shall be taken at the same time as the
concentration measurements.
(3) Calculation of mass flow rate--for noncombustion, nonbiological
treatment processes. The mass flow rates of partially soluble and/or

Subpart HHH--National Emission Standards for Hazardous Air Pollutants
From Natural Gas Transmission and Storage Facilities
Source: 64 FR 32648, June 17, 1999, unless otherwise noted.
Sec. 63.1270 Applicability and designation of affected source.
(a) This subpart applies to owners and operators of natural gas
transmission and storage facilities that transport or store natural gas
prior to entering the pipeline to a local distribution company or to a
final end user (if there is no local distribution company), and that are
major sources of hazardous air pollutants (HAP) emissions as determined
using the maximum natural gas throughput calculated in either paragraph
(a)(1) or (a)(2) of this section and paragraphs (a)(3) and (a)(4) of
this section. A compressor station that transports natural gas prior to
the point of custody transfer, or to a natural gas processing plant (if
present) is considered a part of the oil and natural gas production
source category. A facility that is determined to be an area source,
based on emission estimates using the maximum natural gas throughput
calculated as specified in paragraph (a)(1) or (a)(2) of this section,
but subsequently increases emissions or potential to emit above the
major source levels (without first obtaining and complying with other
limitations that keep its potential to emit HAP below major source
levels, becomes a major source and must comply thereafter with all
applicable provisions of this subpart starting on the applicable
compliance date specified in paragraph (d) of this section. Nothing in
this paragraph is intended to preclude a source from limiting its
potential to emit through other appropriate mechanisms that may be
available through the permitting authority.
(1) Facilities that store natural gas or facilities that transport
and store natural gas shall determine major
[[Page 163]]
source status using the maximum annual facility natural gas throughput
calculated according to paragraphs (a)(1)(i) through (a)(1)(iv) of this
section.
(i) The owner or operator shall determine the number of hours to
complete the storage cycle for the facility. The storage cycle is the
number of hours for the injection cycle, calculated according to the
equation in paragraph (a)(1)(i)(A) of this section, plus the number of
hours for the withdrawal cycle, calculated according to the equation in
paragraph (a)(1)(i)(B) of this section.
(A) The hours for the facility injection cycle are determined
according to the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN99.005
Where:
IC = Facility injection cycle in hours/cycle.
WGC = Working gas capacity in cubic meters. The working gas capacity is
defined as the maximum storage capacity minus the FERC cushion
(as defined in Sec. 63.1271).
IRmax = Maximum facility injection rate in cubic meters per
hour.
(B) The hours for the facility withdrawal cycle are determined
according to the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN99.006
Where:
WC = Facility withdrawal cycle, hours/cycle.
WGC = Working gas capacity, cubic meters. The working gas capacity is
defined as the maximum storage capacity minus the FERC cushion
(as defined in Sec. 63.1271) and shall be the same value as
used in paragraph (a)(1)(i)(A) of this section.
WRmax = Maximum facility withdrawal rate in cubic meters per
hour.
(ii) The owner or operator shall calculate the number of storage
cycles for the facility per year according to the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN99.007
Where:
Cycle = Number of storage cycles for the facility per year.
IC = Number of hours for a facility injection cycle, hours/cycle, as
calculated in paragraph (a)(1)(i)(A) of this section.
WC = Number of hours for a facility withdrawal cycle, hours/cycle, as
calculated in paragraph (a)(1)(i)(B) of this section.
(iii) The owner or operator shall calculate the facilitywide maximum
annual glycol dehydration unit hours of operation based on the following
equation:
Operation = Cycles x WC
Where:
Operation = Facilitywide maximum annual glycol dehydration unit hours of
operation (hr/yr).
Cycles = Number of storage cycles for the facility per year, as
calculated in paragraph (a)(1)(ii) of this section.
WC = Number of hours for a facility withdrawal cycle, hours/cycle, as
calculated in paragraph (a)(1)(i)(B) of this section.
(iv) The owner or operator shall calculate the maximum facilitywide
natural gas throughput based on the following equation:
Throughput = Operation x WRmax
Where:
Throughput = Maximum facilitywide natural gas throughput in cubic meters
per year.
Operation = Maximum facilitywide annual glycol dehydration unit hours of
operation in hours per year, as calculated in paragraph
(a)(1)(iii) of this section.
WRmax = Maximum facility withdrawal rate in cubic meters per
hour.
(2) Facilities that only transport natural gas shall calculate the
maximum natural gas throughput as the highest annual natural gas
throughput over the 5 years prior to June 17, 1999, multiplied by a
factor of 1.2.
(3) The owner or operator shall maintain records of the annual
facility natural gas throughput each year and upon request, submit such
records to the Administrator. If the facility annual natural gas
throughput increases above the maximum natural gas throughput calculated
in paragraph (a)(1) or (a)(2) of this section, the maximum natural gas
throughput must be recalculated using the higher throughput multiplied
by a factor of 1.2.
(4) The owner or operator shall determine the maximum values for
other parameters used to calculate potential emissions as the maximum
over the same period for which maximum
[[Page 164]]
throughput is determined as specified in paragraph (a)(1) or (a)(2) of
this section. These parameters shall be based on an annual average or
the highest single measured value.
(b) The affected source is each glycol dehydration unit.
(c) The owner or operator of a facility that does not contain an
affected source, as specified in paragraph (b) of this section, is not
subject to the requirements of this subpart.
(d) The owner or operator of each affected source shall achieve
compliance with the provisions of this subpart by the following dates:
(1) The owner or operator of an affected source, the construction or
reconstruction of which commenced before February 6, 1998, shall achieve
compliance with this provisions of the subpart no later than June 17,
2002 except as provided for in Sec. 63.6(i). The owner or operator of an
area source, the construction or reconstruction of which commenced
before February 6, 1998, that increases its emissions of (or its
potential to emit) HAP such that the source becomes a major source that
is subject to this subpart shall comply with this subpart 3 years after
becoming a major source.
(2) The owner or operator of an affected source, the construction or
reconstruction of which commences on or after February 6, 1998, shall
achieve compliance with the provisions of this subpart immediately upon
initial startup or June 17, 1999, whichever date is later. Area sources,
the construction or reconstruction of which commences on or after
February 6, 1998, that become major sources shall comply with the
provisions of this standard immediately upon becoming a major source.
(e) An owner or operator of an affected source that is a major
source or is located at a major source and is subject to the provisions
of this subpart is also subject to 40 CFR part 70 or part 71 permitting
requirements.
(f) Exemptions. A facility with a facilitywide actual annual average
natural gas throughput less than 28.3 thousand standard cubic meters per
day, where glycol dehydration units are the only HAP emission source, is
not subject to the requirements of this subpart. Records shall be
maintained as required in Sec. 63.10(b)(3).
Sec. 63.1271 Definitions.
All terms used in this subpart shall have the meaning given to them
in the Clean Air Act, subpart A of this part (General Provisions), and
in this section. If the same term is defined in subpart A and in this
section, it shall have the meaning given in this section for purposes of
this subpart.
Boiler means an enclosed device using controlled flame combustion
and having the primary purpose of recovering and exporting thermal
energy in the form of steam or hot water. Boiler also means any
industrial furnace as defined in 40 CFR 260.10.
Closed-vent system means a system that is not open to the atmosphere
and is composed of piping, ductwork, connections, and if necessary, flow
inducing devices that transport gas or vapor from an emission point to
one or more control devices. If gas or vapor from regulated equipment is
routed to a process (e.g., to a fuel gas system), the conveyance system
shall not be considered a closed-vent system and is not subject to
closed-vent system standards.
Combustion device means an individual unit of equipment, such as a
flare, incinerator, process heater, or boiler, used for the combustion
of organic HAP emissions.
Compressor station means any permanent combination of compressors
that move natural gas at increased pressure from fields, in transmission
pipelines, or into storage.
Continuous recorder means a data recording device that either
records an instantaneous data value at least once every hour or records
hourly or more frequent block average values.
Control device means any equipment used for recovering or oxidizing
HAP or volatile organic compounds (VOC) vapors. Such equipment includes,
but is not limited to, absorbers, carbon adsorbers, condensers,
incinerators, flares, boilers, and process heaters. For the purposes of
this subpart, if gas or vapor from regulated equipment is used, reused
(i.e., injected into the flame zone of a combustion device), returned
back to the process, or sold,
[[Page 165]]
then the recovery system used, including piping, connections, and flow
inducing devices, is not considered to be control devices or closed-vent
systems.
Custody transfer means the transfer of hydrocarbon liquids or
natural gas:
(1) After processing and/or treatment in the producing operations;
or
(2) From storage vessels or automatic transfer facilities, or other
equipment, including product loading racks, to pipelines or any other
forms of transportation.
Facility means any grouping of equipment where natural gas is
processed, compressed, or stored prior to entering a pipeline to a local
distribution company or (if there is no local distribution company) to a
final end user. Examples of a facility for this source category are: an
underground natural gas storage operation; or a natural gas compressor
station that receives natural gas via pipeline, from an underground
natural gas storage operation, or from a natural gas processing plant.
The emission points associated with these phases include, but are not
limited to, process vents. Processes that may have vents include, but
are not limited to, dehydration and compressor station engines.
Facility, for the purpose of a major source determination, means
natural gas transmission and storage equipment that is located inside
the boundaries of an individual surface site (as defined in this
section) and is connected by ancillary equipment, such as gas flow lines
or power lines. Equipment that is part of a facility will typically be
located within close proximity to other equipment located at the same
facility. Natural gas transmission and storage equipment or groupings of
equipment located on different gas leases, mineral fee tracts, lease
tracts, subsurface unit areas, surface fee tracts, or surface lease
tracts shall not be considered part of the same facility.
Federal Energy Regulatory Commission Cushion or FERC Cushion means
the minimum natural gas capacity of a storage field as determined by the
Federal Energy Regulatory Commission.
Flame zone means the portion of the combustion chamber in a
combustion device occupied by the flame envelope.
Flash tank. See the definition for gas-condensate-glycol (GCG)
separator.
Flow indicator means a device which indicates whether gas flow is
present in a line or whether the valve position would allow gas flow to
be present in a line.
Gas-condensate-glycol (GCG) separator means a two-or three-phase
separator through which the ``rich'' glycol stream of a glycol
dehydration unit is passed to remove entrained gas and hydrocarbon
liquid. The GCG separator is commonly referred to as a flash separator
or flash tank.
Glycol dehydration unit means a device in which a liquid glycol
(including, but not limited to, ethylene glycol, diethylene glycol, or
triethylene glycol) absorbent directly contacts a natural gas stream and
absorbs water in a contact tower or absorption column (absorber). The
glycol contacts and absorbs water vapor and other gas stream
constituents from the natural gas and becomes ``rich'' glycol. This
glycol is then regenerated in the glycol dehydration unit reboiler. The
``lean'' glycol is then recycled.
Glycol dehydration unit baseline operations means operations
representative of the glycol dehydration unit operations as of June 17,
1999. For the purposes of this subpart, for determining the percentage
of overall HAP emission reduction attributable to process modifications,
glycol dehydration unit baseline operations shall be parameter values
(including, but not limited to, glycol circulation rate or glycol-HAP
absorbency) that represent actual long-term conditions (i.e., at least 1
year). Glycol dehydration units in operation for less than 1 year shall
document that the parameter values represent expected long-term
operating conditions had process modifications not been made.
Glycol dehydration unit process vent means either the glycol
dehydration unit reboiler vent and the vent from the GCG separator
(flash tank), if present.
Glycol dehydration unit reboiler vent means the vent through which
exhaust from the reboiler of a glycol dehydration unit passes from the
reboiler to the atmosphere or to a control device.
[[Page 166]]
Hazardous air pollutants or HAP means the chemical compounds listed
in section 112(b) of the Clean Air Act (Act). All chemical compounds
listed in section 112(b) of the Act need to be considered when making a
major source determination. Only the HAP compounds listed in Table 1 of
this subpart need to be considered when determining compliance.
Incinerator means an enclosed combustion device that is used for
destroying organic compounds. Auxiliary fuel may be used to heat waste
gas to combustion temperatures. Any energy recovery section is not
physically formed into one manufactured or assembled unit with the
combustion section; rather, the energy recovery section is a separate
section following the combustion section and the two are joined by ducts
or connections carrying flue gas. The above energy recovery section
limitation does not apply to an energy recovery section used solely to
preheat the incoming vent stream or combustion air.
Initial startup means the first time a new or reconstructed source
begins production. For the purposes of this subpart, initial startup
does not include subsequent startups (as defined in this section) of
equipment, for example, following malfunctions or shutdowns.
Major source, as used in this subpart, shall have the same meaning
as in Sec. 63.2, except that:
(1) Emissions from any pipeline compressor station or pump station
shall not be aggregated with emissions from other similar units, whether
or not such units are in a contiguous area or under common control; and
(2) Emissions from processes, operations, and equipment that are not
part of the same facility, as defined in this section, shall not be
aggregated.
Natural gas means a naturally occurring mixture of hydrocarbon and
nonhydrocarbon gases found in geologic formations beneath the earth's
surface. The principal hydrocarbon constituent is methane.
Natural gas transmission means the pipelines used for the long
distance transport of natural gas (excluding processing). Specific
equipment used in natural gas transmission includes the land, mains,
valves, meters, boosters, regulators, storage vessels, dehydrators,
compressors, and their driving units and appurtenances, and equipment
used for transporting gas from a production plant, delivery point of
purchased gas, gathering system, storage area, or other wholesale source
of gas to one or more distribution area(s).
No detectable emissions means no escape of HAP from a device or
system to the atmosphere as determined by:
(1) Instrument monitoring results in accordance with the
requirements of Sec. 63.1282(b); and
(2) The absence of visible openings or defects in the device or
system, such as rips, tears, or gaps.
Operating parameter value means a minimum or maximum value
established for a control device or process parameter which, if achieved
by itself or in combination with one or more other operating parameter
values, indicates that an owner or operator has complied with an
applicable operating parameter limitation, over the appropriate
averaging period as specified in Sec. 63.1282 (e) and (f).
Operating permit means a permit required by 40 CFR part 70 or part
71.
Organic monitoring device means an instrument used to indicate the
concentration level of organic compounds exiting a control device based
on a detection principle such as infra-red, photoionization, or thermal
conductivity.
Primary fuel means the fuel that provides the principal heat input
(i.e., more than 50 percent) to the device. To be considered primary,
the fuel must be able to sustain operation without the addition of other
fuels.
Process heater means an enclosed device using a controlled flame,
the primary purpose of which is to transfer heat to a process fluid or
process material that is not a fluid, or to a heat transfer material for
use in a process (rather than for steam generation) .
Safety device means a device that meets both of the following
conditions: the device is not used for planned or routine venting of
liquids, gases, or fumes from the unit or equipment on which the device
is installed; and the
[[Page 167]]
device remains in a closed, sealed position at all times except when an
unplanned event requires that the device open for the purpose of
preventing physical damage or permanent deformation of the unit or
equipment on which the device is installed in accordance with good
engineering and safety practices for handling flammable, combustible,
explosive, or other hazardous materials. Examples of unplanned events
which may require a safety device to open include failure of an
essential equipment component or a sudden power outage.
Shutdown means for purposes including, but not limited to, periodic
maintenance, replacement of equipment, or repair, the cessation of
operation of a glycol dehydration unit, or other affected source under
this subpart, or equipment required or used solely to comply with this
subpart.
Startup means the setting into operation of a glycol dehydration
unit, or other affected equipment under this subpart, or equipment
required or used to comply with this subpart. Startup includes initial
startup and operation solely for the purpose of testing equipment.
Storage vessel means a tank or other vessel that is designed to
contain an accumulation of crude oil, condensate, intermediate
hydrocarbon liquids, produced water, or other liquid, and is constructed
primarily of non-earthen materials (e.g., wood, concrete, steel,
plastic) that provide structural support.
Surface site means any combination of one or more graded pad sites,
gravel pad sites, foundations, platforms, or the immediate physical
location upon which equipment is physically affixed.
Temperature monitoring device means an instrument used to monitor
temperature and having a minimum accuracy of 2 percent of
the temperature being monitored expressed in deg.C, or 2.5
deg.C, whichever is greater. The temperature monitoring device may
measure temperature in degrees Fahrenheit or degrees Celsius, or both.
Total organic compounds or TOC, as used in this subpart, means those
compounds which can be measured according to the procedures of Method
18, 40 CFR part 60, appendix A.
Underground storage means the subsurface facilities utilized for
storing natural gas that has been transferred from its original location
for the primary purpose of load balancing, which is the process of
equalizing the receipt and delivery of natural gas. Processes and
operations that may be located at an underground storage facility
include, but are not limited to, compression and dehydration.
Sec. 63.1272 Startups, shutdowns, and malfunctions.
(a) The provisions set forth in this subpart shall apply at all
times except during startups or shutdowns, during malfunctions, and
during periods of non-operation of the affected sources (or specific
portion thereof) resulting in cessation of the emissions to which this
subpart applies. However, during the startup, shutdown, malfunction, or
period of non-operation of one portion of an affected source, all
emission points which can comply with the specific provisions to which
they are subject must do so during the startup, shutdown, malfunction,
or period of non-operation.
(b) The owner or operator shall not shut down items of equipment
that are required or utilized for compliance with the provisions of this
subpart during times when emissions are being routed to such items of
equipment, if the shutdown would contravene requirements of this subpart
applicable to such items of equipment. This paragraph does not apply if
the item of equipment is malfunctioning, or if the owner or operator
must shut down the equipment to avoid damage due to a contemporaneous
startup, shutdown, or malfunction of the affected source or a portion
thereof.
(c) During startups, shutdowns, and malfunctions when the
requirements of this subpart do not apply pursuant to paragraphs (a) and
(b) of this section, the owner or operator shall implement, to the
extent reasonably available, measures to prevent or minimize excess
emissions to the maximum extent practical. For purposes of this
paragraph, the term ``excess emissions'' means emissions in excess of
those that would have occurred if there were no startup, shutdown, or
malfunction, and
[[Page 168]]
the owner or operator complied with the relevant provisions of this
subpart. The measures to be taken shall be identified in the applicable
startup, shutdown, and malfunction plan, and may include, but are not
limited to, air pollution control technologies, recovery technologies,
work practices, pollution prevention, monitoring, and/or changes in the
manner of operation of the source. Back-up control devices are not
required, but may be used if available.
(d) The owner or operator shall prepare a startup, shutdown, or
malfunction plan as required in Sec. 63.6(e)(3) except that the plan is
not required to be incorporated by reference into the source's title V
permit as specified in Sec. 63.6(e)(3)(i). Instead, the owner or
operator shall keep the plan on record as required by
Sec. 63.6(e)(3)(v). The failure of the plan to adequately minimize
emissions during the startup, shutdown, or malfunction does not shield
an owner or operator from enforcement actions.
Sec. 63.1273 [Reserved]
Sec. 63.1274 General standards.
(a) Table 2 of this subpart specifies the provisions of subpart A
(General Provisions) that apply and those that do not apply to owners
and operators of affected sources subject to this subpart.
(b) All reports required under this subpart shall be sent to the
Administrator at the appropriate address listed in Sec. 63.13. Reports
may be submitted on electronic media.
(c) Except as specified in paragraph (d) of this section, the owner
or operator of an affected source (i.e., glycol dehydration unit)
located at an existing or new major source of HAP emissions shall comply
with the requirements in this subpart as follows:
(1) The control requirements for glycol dehydration unit process
vents specified in Sec. 63.1275;
(2) The monitoring requirements specified in Sec. 63.1283, and
(3) The recordkeeping and reporting requirements specified in
Secs. 63.1284 and 63.1285.
(d) Exemptions. The owner or operator is exempt from the
requirements of paragraph (c) of this section if the criteria listed in
paragraph (d)(1) or (d)(2) of this section are met. Records of the
determination of these criteria must be maintained as required in
Sec. 63.1284(d) of this subpart.
(1) The actual annual average flow of gas to the glycol dehydration
unit is less than 283 thousand standard cubic meters per day, as
determined by the procedures specified in Sec. 63.1282(a)(1) of this
subpart; or
(2) The actual average emissions of benzene from the glycol
dehydration unit process vents to the atmosphere are less than 0.90
megagram per year as determined by the procedures specified in
Sec. 63.1282(a)(2) of this subpart.
(e) Each owner or operator of a major HAP source subject to this
subpart is required to apply for a part 70 or part 71 operating permit
from the appropriate permitting authority. If the Administrator has
approved a State operating permit program under part 70, the permit
shall be obtained from the State authority. If a State operating permit
program has not been approved, the owner or operator shall apply to the
EPA Regional Office pursuant to part 71.
(f) [Reserved]
(g) In all cases where the provisions of this subpart require an
owner or operator to repair leaks by a specified time after the leak is
detected, it is a violation of this standard to fail to take action to
repair the leak(s) within the specified time. If action is taken to
repair the leak(s) within the specified time, failure of that action to
successfully repair the leak(s) is not a violation of this standard.
However, if the repairs are unsuccessful, a leak is detected and the
owner or operator shall take further action as required by the
applicable provisions of this subpart.

flow indicator indicates that flow has been detected and that the stream
has been diverted away from the control device to the atmosphere.
(B) For each bypass line subject to Sec. 63.1281(c)(3)(i)(B), if the
seal or closure mechanism has been broken, the bypass line valve
position has changed, the key for the lock-and-key type lock has been

(7) For each excursion, except as provided for in paragraph (d)(8)
of this section, the owner or operator shall be deemed to have failed to
have applied control in a manner that achieves the required operating
parameter limits. Failure to achieve the required operating parameter
limits is a violation of this standard.
(8) An excursion is not a violation of the operating parameter limit
as specified in paragraphs (d)(8)(i) and (d)(8)(ii) of this section.
(i) An excursion does not count toward the number of excused
excursions allowed under paragraph (d)(8)(ii) of this section when the
excursion occurs during any one of the following periods:
[[Page 182]]
(A) During a period of startup, shutdown, or malfunction when the
affected facility is operated during such period in accordance with the
facility's startup, shutdown, and malfunction plan; or
(B) During periods of non-operation of the unit or the process that
is vented to the control device (resulting in cessation of HAP emissions
to which the monitoring applies).
(ii) For each control device, or combinations of control devices,
installed on the same HAP emissions unit, one excused excursion is
allowed per semiannual period for any reason. The initial semiannual
period is the 6-month reporting period addressed by the first Periodic

Subpart III--National Emission Standards for Hazardous Air Pollutants
for Flexible Polyurethane Foam Production
Source: 63 FR 53996, Oct. 7, 1998, unless otherwise noted.
Sec. 63.1290 Applicability.
(a) The provisions of this subpart apply to each new and existing
flexible polyurethane foam or rebond foam process that meets the
criteria listed in paragraphs (a)(1) through (3) of this section.
(1) Produces flexible polyurethane or rebond foam;
(2) Emits a HAP, except as provided in paragraph (c)(2) of this
section; and
(3) Is located at a plant site that is a major source, as defined in
Sec. 63.2 of subpart A.
(b) For the purpose of this subpart, an affected source includes all
processes meeting the criteria in paragraphs (a)(1) through (a)(3) of
this section that are located at a contiguous plant site, with the
exception of those processes listed in paragraph (c) of this section.
(c) A process meeting one of the following criteria listed in
paragraphs (c)(1) through (3) of this section shall not be subject to
the provisions of this subpart:
(1) A process exclusively dedicated to the fabrication of flexible
polyurethane foam;
(2) A research and development process; or
(3) A slabstock flexible polyurethane foam process at a plant site
where the total amount of HAP, excluding diisocyanate reactants, used
for slabstock foam production and foam fabrication is less than or equal
to five tons per year, provided that slabstock foam production and foam
fabrication processes are the only processes at the plant site that emit
HAP. The amount of non-diisocyanate HAP used, HAPused, shall
be calculated using Equation 1. Owners or operators of slabstock foam
processes exempt from the regulation in accordance with this paragraph
shall maintain records to verify that total non-diisocyanate HAP use at
the plant site is less than 5 tons per year (4.5 megagrams per year).

Sec. 63.1292 Definitions.
All terms used in this subpart shall have the meaning given them in
the Act, in subpart A of this part, and in this section. If a term is
defined in subpart A and in this section, it shall have the meaning
given in this section for purposes of this subpart.
Auxiliary blowing agent, or ABA, means a low-boiling point liquid
added to assist foaming by generating gas beyond that resulting from the
isocyanate-water reaction.
Breakthrough means that point in the adsorption step when the mass
transfer zone (i.e., the section of the carbon bed where the HAP is
removed from the carrier gas stream) first reaches the carbon bed outlet
as the mass transfer zone moves down the bed in the direction of flow.
The breakthrough point is characterized by the beginning of a sharp
increase in the outlet HAP or organic compound concentration.
Calibrate means to verify the accuracy of a measurement device
against a known standard. For the purpose of this subpart, there are two
levels of calibration. The initial calibration includes the verification
of the accuracy of the device over the entire operating range of the
device. Subsequent calibrations can be conducted for a point or several
points in a limited range of operation that represents the most common
operation of the device.
Canned motor pump means a pump with interconnected cavity housings,
motor rotors, and pump casing. In a canned motor pump, the motor
bearings run in the process liquid and all seals are eliminated.
Carbon adsorption system means a system consisting of a tank or
container that contains a specific quantity of activated carbon. For the
purposes of this subaprt, a carbon adsorption system is used as a
control device for storage vessels. Typically, the spent carbon bed does
not undergo regeneration, but is replaced.
Connector means flanged, screwed, or other joined fittings used to
connect two pipe lines or a pipe line and a piece of equipment. A common
connector is a flange. Joined fittings welded completely around the
circumference of the interface are not considered to be connectors for
the purposes of this subpart.
Cured foam means flexible polyurethane foam with fully developed
physical properties. A period of 12 to 24 hours from pour is typically
required to completely cure foam, although mechanical or other devices
are sometimes used to accelerate the curing process.
Curing area means the area in a slabstock foam production facility
where foam buns are allowed to fully develop physical properties.
Diaphragm pump means a pump where the driving member is a flexible
diaphragm made of metal, rubber, or plastic. In a diaphragm pump, there
is no packing or seals that are exposed to the process liquid.
Diisocyanate means a compound containing two isocyanate groups per
molecule. The most common diisocyanate compounds used in the flexible
polyurethane foam industry are toluene diisocyanate (TDI) and methylene
diphenyl diisocyanate (MDI).
Flexible polyurethane foam means a flexible cellular polymer
containing urea and carbamate linkages in the chain backbone produced by
reacting a diisocyanate, polyol, and water. Flexible polyurethane foams
are open-celled, permit the passage of air through the foam, and possess
the strength and flexibility to allow repeated distortion or compression
under stress with essentially complete recovery upon removal of the
stress.
Flexible polyurethane foam process means the equipment used to
produce a flexible polyurethane foam product. For the purpose of this
subpart, the flexible polyurethane foam process includes raw material
storage; production equipment and associated piping, ductwork, etc.; and

rolling annual basis, actual HAP ABA emissions shall be compared to
allowable HAP ABA emissions for each consecutive 12-month period. The
allowable HAP ABA emission level shall be calculated based on the
production for the 12-month period, resulting in a potentially different
allowable level for each 12-month period. Compliance shall be determined
each month for the previous 12-month period. The compliance requirements
are provided in paragraph (b) of this section.
(2) Monthly compliance alternative. As an alternative to determining
compliance on a rolling annual basis, an owner or operator can determine
compliance by comparing actual HAP ABA emissions to allowable HAP ABA
emissions for each month. The allowable HAP ABA emission level shall be
calculated based on the production for the month, resulting in a
potentially different allowable level each month. The requirements for
this monthly compliance alternative are provided in paragraph (c) of
this section.

methods described under paragraphs (a)(1) and (a)(2) of this section
shall notify the Administrator no later than 180 calendar days prior to
the change.
(b) Rolling annual compliance. At each slabstock foam production
source complying with the rolling annual compliance provisions described
in paragraph (a)(1) of this section, actual HAP ABA emissions shall not
exceed the allowable HAP ABA emission level for a consecutive 12-month
period. The actual HAP ABA emission level for a consecutive 12-month
period shall be determined using the procedures in paragraph (b)(1) of
this section, and the allowable HAP ABA emission level for the
corresponding 12-month period shall be calculated in accordance with
paragraph (b)(2) of this section.
(1) The actual HAP ABA emissions for a 12-month period shall be
calculated as the sum of actual monthly HAP ABA emissions for each of
the individual 12 months in the period. Actual monthly HAP ABA emissions
shall be equal to the amount of HAP ABA added to the slabstock foam
production line at the mixhead, determined in accordance with
Sec. 63.1303(b), unless a recovery device is used. Slabstock foam
production sources using recovery devices to reduce HAP ABA emissions
shall determine actual monthly HAP ABA emissions using the procedures in
paragraph (e) of this section.
(2) The allowable HAP ABA emissions for a consecutive 12-month
period shall be calculated as the sum of allowable monthly HAP ABA

provisions, actual source-wide HAP ABA storage and equipment leak
emissions, HAP ABA emissions from the production line, and equipment
cleaning HAP emissions are compared to allowable source-wide emissions
for each consecutive 12-month period. The allowable source-wide HAP
emission level is calculated based on the production for the 12-month
period, resulting in a potentially different allowable level for each
12-month period. While compliance is on an annual basis, compliance
shall be determined monthly for the preceding 12-month period. The
actual source-wide HAP emission level for a consecutive 12-month period
shall be determined using the procedures in
[[Page 200]]
paragraphs (c)(1) through (4) of this section, unless a recovery device
is used. Slabstock foam production sources using recovery devices shall
determine actual source-wide HAP emissions in accordance with paragraph
(e) of this section. The allowable HAP emission level for a consecutive
12-month period shall be determined using the procedures in paragraph
(d) of this section.

compliance on a rolling annual basis, an owner or operator can determine
compliance by comparing actual HAP emissions to allowable HAP emissions
for each month. The allowable source-wide emission level is calculated
based on the production for the month, resulting in a potentially
different allowable level each month. The actual monthly emission level
shall be determined using the procedures in paragraphs (c)(1) through
(3) of this section, unless a recovery device is used. Slabstock foam
production sources using recovery devices shall determine actual source-
wide HAP emissions in accordance with paragraph (e) of this section. The

Method 21 of 40 CFR part 60, appendix A, except that the instrument
response factor criteria in section 3.1.2(a) of Method 21 shall be for
the average composition of the source fluid, rather than for each
individual VOC in the stream. For source streams that contain nitrogen,
air, or other inerts which are not HAP or VOC, the average stream
response factor shall be calculated on an inert-free basis. The response
factor may be determined at any concentration for which monitoring for
leaks will be conducted.
(3) The instrument shall be calibrated before use on each day of its
use by the procedures specified in Method 21 of 40 CFR part 60, appendix
A.
(4) Calibration gases shall be:
(i) Zero air (less than 10 ppm of hydrocarbon in air); and
(ii) A mixture of methane and air at a concentration of
approximately, 1,000 ppm for all transfer pumps; and 500 ppm for all
other equipment, except as provided in paragraph (a)(4)(iii) of this
section.
(iii) The instrument may be calibrated at a higher methane
concentration (up to 2,000 ppm) than the leak definition concentration
for a specific piece of equipment for monitoring that piece of
equipment. If the monitoring instrument's design allows for multiple
calibration gas concentrations, then the lower concentration calibration
gas shall be no higher than 2,000 ppm methane and the higher
concentration calibration gas shall be no higher than 10,000 ppm
methane.
(5) Monitoring shall be performed when the equipment is in HAP ABA
service, in use with an acceptable surrogate volatile organic compound
which is not a HAP ABA, or is in use with any other detectable gas or
vapor.
(6) If no instrument is available onsite that will meet the
performance criteria specified in section 3.1.2(a) of Method 21 of 40
CFR Part 60, appendix A, the readings from an available instrument may
be adjusted by multiplying by the average response factor for the
stream.
(b) Test method to determine foam properties. The IFD and density of
each grade of foam produced during each run of foam shall be determined
using ASTM D3574-91, Standard Test Methods for Flexible Cellular
Materials--Slab, Bonded, and Molded (incorporation by reference--see
Sec. 63.14), using a sample of foam cut from the center of the foam bun.
The maximum sample size for which the IFD and density is determined
shall not be larger than 24 inches by 24 inches by 4 inches. For grades
of foam where the owner or operator has designated the HAP ABA
formulation limitation as zero, the owner or operator is not required to
determine the IFD and density in accordance with this paragraph.

Source: 61 FR 48229, Sept. 12, 1996, unless otherwise noted.
Sec. 63.1310 Applicability and designation of affected sources.
(a) Definition of affected source. The provisions of this subpart
apply to each affected source. Affected sources are described in
paragraphs (a)(1) through (a)(4) of this section.
(1) An affected source is either an existing affected source or a
new affected source. Existing affected source is defined in paragraph
(a)(2) of this section, and new affected source is defined in paragraph
(a)(3) of this section.
(2) An existing affected source is defined as each group of one or
more thermoplastic product process units (TPPU) and associated
equipment, as listed in paragraph (a)(4) of this section that is not
part of a new affected source, as defined in paragraph (a)(3) of this
section, that is manufacturing the same primary product, and that is
located at a plant site that is a major source.
(3) A new affected source is defined by the criteria in paragraph
(a)(3)(i), (a)(3)(ii), or (a)(3)(iii) of this section. The situation
described in paragraph (a)(3)(i) of this section is distinct from those
situations described in paragraphs (a)(3)(ii) and (a)(3)(iii) of this
section and from any situation described in paragraph (i) of this
section.
(i) At a site without HAP emission points before March 29, 1995
(i.e., a ``greenfield'' site), each group of one or more TPPU and
associated equipment, as listed in paragraph (a)(4) of this section,
that is manufacturing the same primary product and that is part of a
major source on which construction commenced after March 29, 1995;
(ii) A group of one or more TPPU meeting the criteria in paragraph
(i)(1)(i) of this section; or
(iii) A reconstructed affected source meeting the criteria in
paragraph (i)(2)(i) of this section.
(4) Emission points and equipment. The affected source also includes
the emission points and equipment specified in paragraphs (a)(4)(i)
through (a)(4)(vi) of this section that are associated with each
applicable group of one or more TPPU constituting an affected source.
(i) Each waste management unit.

PET using a continuous terephthalic acid high viscosity multiple end
finisher process that is associated with an existing affected source.
(vi) Equipment required by, or utilized as a method of compliance
with, this subpart which may include control devices and recovery
devices.
(5) TPPUs and associated equipment, as listed in paragraph (a)(4) of
this section, that are located at plant sites that are not major sources
are neither affected sources nor part of an affected source.
(b) TPPUs without organic HAP. The owner or operator of a TPPU that
is part of an affected source, as defined in paragraph (a) of this
section, but that
[[Page 220]]
does not use or manufacture any organic HAP shall comply with the
requirements of either paragraph (b)(1) or (b)(2) of this section. Such
a TPPU is not subject to any other provisions of this subpart and is not
required to comply with the provisions of subpart A of this part.
(1) Retain information, data, and analyses used to document the
basis for the determination that the TPPU does not use or manufacture
any organic HAP. Types of information that could document this
determination include, but are not limited to, records of chemicals
purchased for the process, analyses of process stream composition,
engineering calculations, or process knowledge.
(2) When requested by the Administrator, demonstrate that the TPPU
does not use or manufacture any organic HAP.
(c) Emission points not subject to the provisions of this subpart.
The affected source includes the emission points listed in paragraphs
(c)(1) through (c)(9) of this section, but these emission points are not
subject to the requirements of this subpart or to the provisions of
subpart A of this part.
(1) Equipment that does not contain organic HAP and is located
within a TPPU that is part of an affected source;
(2) Stormwater from segregated sewers;
(3) Water from fire-fighting and deluge systems in segregated
sewers;
(4) Spills;
(5) Water from safety showers;
(6) Water from testing of deluge systems;
(7) Water from testing of firefighting systems;
(8) Vessels and equipment storing and/or handling material that
contain no organic HAP and/or organic HAP as impurities only; and
(9) Equipment that is intended to operate in organic HAP service for
less than 300 hours during the calendar year.
(d) Processes exempted from the affected source. The processes
specified in paragraphs (d)(1) through (d)(5) of this section are
exempted from the affected source:
(1) Research and development facilities;
(2) Polymerization processes occurring in a mold;
(3) Processes which manufacture binder systems containing a
thermoplastic product for paints, coatings, or adhesives;
(4) Finishing processes including equipment such as compounding
units, spinning units, drawing units, extruding units, and other
finishing steps; and
(5) Solid state polymerization processes.
(e) Applicability determination of nonthermoplastic equipment
included within the boundaries of a TPPU. If a polymer that is not a
thermoplastic product is produced within the equipment (i.e.,
collocated) making up a TPPU and at least 50 percent of that polymer is
used in the production of a thermoplastic product manufactured by the
same TPPU, then the unit operations involved in the production of that
polymer are considered part of the TPPU and are subject to this subpart,
with the following exception. Any emission points from such unit
operations that are subject to another subpart of this part with an
effective date prior to September 5, 1996 shall remain subject to that
other subpart of this part and are not subject to this subpart.
(f) Primary product determination and applicability. An owner or
operator of a process unit that produces or plans to produce a
thermoplastic product shall determine if the process unit is subject to
this subpart in accordance with this paragraph. The owner or operator
shall initially determine whether a process unit is designated as a TPPU
and subject to the provisions of this subpart in accordance with either
paragraph (f)(1) or (f)(2) of this section. The owner or operator of a
flexible operation unit that was not initially designated as a TPPU, but
in which a thermoplastic product is produced, shall conduct an annual
re-determination of the applicability of this subpart in accordance with
paragraph (f)(3) of this section. Owners or operators that anticipate
the production of a thermoplastic product in a process unit that was not
initially designated as a TPPU, and in which no thermoplastic products
are
[[Page 221]]
currently produced, shall determine if the process unit is subject to
this subpart in accordance with paragraph (f)(4) of this section.
Paragraphs (f)(3) and (f)(5) through (f)(7) of this section discuss
compliance only for flexible operation units. Other paragraphs apply to
all process units, including flexible operation units, unless otherwise
noted. Paragraph (f)(8) of this section contains reporting requirements
associated with the applicability determinations. Paragraphs (f)(9) and
(f)(10) of this section describe criteria for removing the TPPU
designation from a process unit.
(1) Initial determination. The owner or operator shall initially
determine if a process unit is subject to the provisions of this subpart
based on the primary product of the process unit in accordance with
paragraphs (f)(1)(i) through (iii) of this section. If the process unit
never uses or manufactures any organic HAP, regardless of the outcome of
the primary product determination, the only requirements of this subpart
that might apply to the process unit are contained in paragraph (b) of
this section. If a flexible operation unit does not use or manufacture
any organic HAP during the manufacture of one or more products,
paragraph (f)(5)(i) of this section applies to that flexible operation
unit.
(i) If a process unit only manufactures one product, then that
product shall represent the primary product of the process unit.
(ii) If a process unit produces more than one intended product at
the same time, the primary product shall be determined in accordance
with paragraph (f)(1)(ii)(A) or (B) of this section.
(A) The product for which the process unit has the greatest annual
design capacity on a mass basis shall represent the primary product of
the process unit, or
(B) If a process unit has the same maximum annual design capacity on
a mass basis for two or more products, and if one of those products is a
thermoplastic product, then the thermoplastic product shall represent
the primary product of the process unit.
(iii) If a process unit is designed and operated as a flexible
operation unit, the primary product shall be determined as specified in
paragraphs (f)(1)(iii)(A) or (B) of this section based on the
anticipated operations for the 5 years following September 12, 1996 at
existing process units, or for the first year after the process unit
begins production of any product for new process units. If operations
cannot be anticipated sufficiently to allow the determination of the
primary product for the specified period, applicability shall be
determined (in accordance with paragraph (f)(2) of this section.
(A) If the flexible operation unit will manufacture one product for
the greatest operating time over the specified 5 year period for
existing process units, or the specified 1 year period for new process
units, then that product shall represent the primary product of the
flexible operation unit.
(B) If the flexible operation unit will manufacture multiple
products equally based on operating time, then the product with the
greatest expected production on a mass basis over the specified 5 year
period for existing process units, or the specified 1 year period for
new process units shall represent the primary product of the flexible
operation unit.
(iv) If, according to paragraph (f)(1)(i), (ii), or (iii) of this
section, the primary product of a process unit is a thermoplastic
product, then that process unit shall be designated as a TPPU. That TPPU
and associated equipment, as listed in paragraph (a)(4) of this section
is either an affected source or part of an affected source comprised of
other TPPU and associated equipment, as listed in paragraph (a)(4) of
this section, subject to this subpart with the same primary product at
the same plant site that is a major source. If the primary product of a
process unit is determined to be a product that is not a thermoplastic
product, then that process unit is not a TPPU.
(2) If the primary product cannot be determined for a flexible
operation unit in accordance with paragraph (f)(1)(iii) of this section,
applicability shall be determined in accordance with this paragraph.
(i) If the owner or operator cannot determine the primary product in
accordance with paragraph (f)(1)(iii) of this section, but can determine
that a
[[Page 222]]
thermoplastic product is not the primary product, then that flexible
operation unit is not a TPPU.
(ii) If the owner or operator cannot determine the primary product
in accordance with paragraph (f)(1)(iii) of this section, and cannot
determine that a thermoplastic product is not the primary product as
specified in paragraph (f)(2)(i) of this section, applicability shall be
determined in accordance with paragraph (f)(2)(ii)(A) or (f)(2)(ii)(B)
of this section.
(A) If the flexible operation unit is an existing process unit, the
flexible operation unit shall be designated as a TPPU if a thermoplastic
product was produced for 5 percent or greater of the total operating
time of the flexible operating unit since March 9, 1999. That TPPU and
associated equipment, as listed in paragraph (a)(4) of this section, is
either an affected source, or part of an affected source comprised of
other TPPU and associated equipment, as listed in paragraph (a)(4) of
this section, subject to this subpart with the same primary product at
the same plant site that is a major source. For a flexible operation
unit that is designated as an TPPU in accordance with this paragraph,
the thermoplastic product produced for the greatest amount of time since
March 9, 1999 shall be designated as the primary product of the TPPU.
(B) If the flexible operation unit is a new process unit, the
flexible operation unit shall be designated as a TPPU if the owner or
operator anticipates that a thermoplastic product will be manufactured
in the flexible operation unit at any time in the first year after the
date the unit begins production of any product. That TPPU and associated
equipment, as listed in paragraph (a)(4) of this section, is either an
affected source, or part of an affected source comprised of other TPPU
and associated equipment, as listed in paragraph (a)(4) of this section,
subject to this subpart with the same primary product at the same plant
site that is a major source. For a process unit that is designated as a
TPPU in accordance with this paragraph, the thermoplastic product that
will be produced shall be designated as the primary product of the TPPU.
If more than one thermoplastic product will be produced, the owner or
operator may select which thermoplastic product is designated as the
primary product.
(3) Annual applicability determination for non-TPPUs that have
produced a thermoplastic product. Once per year beginning September 12,
2001, the owner or operator of each flexible operation unit that is not
designated as a TPPU, but that has produced a thermoplastic product at
any time in the preceding 5-year period or since the date that the unit
began production of any product, whichever is shorter, shall perform the
evaluation described in paragraphs (f)(3)(i) through (f)(3)(iii) of this
section. However, an owner or operator that does not intend to produce
any thermoplastic product in the future, in accordance with paragraph
(f)(9) of this section, is not required to perform the evaluation
described in paragraphs (f)(3)(i) through (f)(3)(iii) of this section.
(i) For each product produced in the flexible operation unit, the
owner or operator shall calculate the percentage of total operating time
over which the product was produced during the preceding 5-year period.
(ii) The owner or operator shall identify the primary product as the
product with the highest percentage of total operating time for the
preceding 5-year period.
(iii) If the primary product identified in paragraph (f)(3)(ii) is a
thermoplastic product, the flexible operation unit shall be designated
as a TPPU. The owner or operator shall notify the Administrator no later
than 45 days after determining that the flexible operation unit is a
TPPU, and shall comply with the requirements of this subpart in
accordance with paragraph (i)(1) of this section for the flexible
operation unit.
(4) Applicability determination for non-TPPUs that have not produced
a thermoplastic product. The owner or operator that anticipates the
production of a thermoplastic product in a process unit that is not
designated as a TPPU, and in which no thermoplastic products have been
produced in the previous 5-year period or since the date that the
process unit began production of any
[[Page 223]]
product, whichever is shorter, shall determine if the process unit is
subject to this subpart in accordance with paragraphs (f)(4)(i) and (ii)
of this section. Also, owners or operators who have notified the
Administrator that a process unit is not a TPPU in accordance with
paragraph (f)(9) of this section, that now anticipate the production of
a thermoplastic product in the process unit, shall determine if the
process unit is subject to this subpart in accordance with paragraphs
(f)(4)(i) and (ii) of this section.
(i) The owner or operator shall use the procedures in paragraph
(f)(1) or (f)(2) of this section to determine if the process unit is
designated as a TPPU, with the following exception: For existing process
units that are determining the primary product in accordance with
paragraph (f)(1)(iii) of this section, production shall be projected for
the five years following the date that the owner or operator anticipates
initiating the production of a thermoplastic product.
(ii) If the unit is designated as a TPPU in accordance with
paragraph (f)(4)(i) of this section, the owner or operator shall comply
in accordance with paragraph (i)(1) of this section.
(5) Compliance for flexible operation units. Owners or operators of
TPPUs that are flexible operation units shall comply with the standards
specified for the primary product, with the exceptions provided in
paragraphs (f)(5)(i) and (f)(5)(ii) of this section.
(i) Whenever a flexible operation unit manufactures a product in
which no organic HAP is used or manufactured, the owner or operator is
only required to comply with either paragraph (b)(1) or (b)(2) of this
section to demonstrate compliance for activities associated with the
manufacture of that product. This subpart does not require compliance
with the provisions of subpart A of this part for activities associated
with the manufacture of a product that meets the criteria of paragraph
(b) of this section.
(ii) Whenever a flexible operation unit manufactures a product that
makes it subject to subpart GGG of this part, the owner or operator is
not required to comply with the provisions of this subpart during the
production of that product.
(6) Owners or operators of TPPUs that are flexible operation units
have the option of determining the group status of each emission point
associated with the flexible operation unit, in accordance with either
paragraph (f)(6)(i) or (f)(6)(ii) of this section, with the exception of
batch process vents. For batch process vents, the owner or operator
shall determine the group status in accordance with Sec. 63.1323.
(i) The owner or operator may determine the group status of each
emission point based on emission point characteristics when the primary
product is being manufactured. The criteria that shall be used for this
group determination are the Group 1 criteria specified for the primary
product.
(ii) The owner or operator may determine the group status of each
emission point separately for each product produced by the flexible
operation unit. For each product, the group status shall be determined
using the emission point characteristics when that product is being
manufactured and using the Group 1 criteria specified for the primary
product. (Note: Under this scenario, it is possible that the group
status, and therefore the requirement to achieve emission reductions,
for an emission point may change depending on the product being
manufactured.)
(7) Owners or operators determining the group status of emission
points in flexible operation units based solely on the primary product
in accordance with paragraph (f)(6)(i) of this section shall establish
parameter monitoring levels, as required, in accordance with either
paragraph (f)(7)(i) or (f)(7)(ii) of this section. Owners or operators
determining the group status of emission points in flexible operation
units based on each product in accordance with paragraph (f)(6)(ii) of
this section shall establish parameter monitoring levels, as required,
in accordance with paragraph (f)(7)(i) of this section.
(i) Establish separate parameter monitoring levels in accordance
with Sec. 63.1334(a) for each individual product.
(ii) Establish a single parameter monitoring level (for each
parameter
[[Page 224]]
required to be monitored at each device subject to monitoring
requirements) in accordance with Sec. 63.1334(a) that would apply for
all products.
(8) Reporting requirements. When it is determined that a process
unit is a TPPU and subject to the requirements of this subpart, the
Notification of Compliance Status required by Sec. 63.1335(e)(5) shall
include the information specified in paragraphs (f)(8)(i) and (f)(8)(ii)
of this section, as applicable. If it is determined that the process
unit is not subject to this subpart, the owner or operator shall either
retain all information, data, and analysis used to document the basis
for the determination that the primary product is not a thermoplastic
product, or, when requested by the Administrator, demonstrate that the
process unit is not subject to this subpart.
(i) If the TPPU manufactures only one thermoplastic product,
identification of that thermoplastic product.
(ii) If the TPPU is designed and operated as a flexible operation
unit, the information specified in paragraphs (f)(8)(ii)(A) through
(f)(8)(ii)(D) of this section, as appropriate, shall be submitted.
(A) If a primary product could be determined, identification of the
primary product.
(B) Identification of which compliance option, either paragraph
(f)(6)(i) or (f)(6)(ii) of this section, has been selected by the owner
or operator.
(C) If the option to establish separate parameter monitoring levels
for each product in paragraph (f)(7)(i) of this section is selected, the
identification of each product and the corresponding parameter
monitoring level.
(D) If the option to establish a single parameter monitor level in
paragraph (f)(7)(ii) of this section is selected, the parameter
monitoring level for each parameter.
(9) TPPUs terminating production of all thermoplastic products. If a
TPPU terminates the production of all thermoplastic products and does
not anticipate the production of any thermoplastic products in the
future, the process unit is no longer a TPPU and is not subject to this
subpart after notification is made to the Administrator. This
notification shall be accompanied by a rationale for why it is
anticipated that no thermoplastic products will be produced in the
process unit in the future.
(10) Redetermination of applicability to TPPUs that are flexible
operation units. Whenever changes in production occur that could
reasonably be expected to change the primary product of a TPPU that is
operating as a flexible operation unit from a thermoplastic product to a
product that would make the process unit subject to another subpart of
this part, the owner or operator shall re-evaluate the status of the
process unit as a TPPU in accordance with paragraphs (f)(10)(i) through
(iii) of this section.
(i) For each product produced in the flexible operation unit, the
owner or operator shall calculate the percentage of total operating time
in which the product was produced for the preceding five-year period, or
since the date that the process unit began production of any product,
whichever is shorter.
(ii) The owner or operator shall identify the primary product as the
product with the highest percentage of total operating time for the
period.
(iii) If the conditions in (f)(10)(iii)(A) through (C) of this
section are met, the flexible operation unit shall no longer be
designated as a TPPU and shall no longer be subject to the provisions of
this subpart after the date that the process unit is required to be in
compliance with the provisions of the other subpart of this part to
which it is subject. If the conditions in paragraphs (f)(10)(iii)(A)
through (C) of this section are not met, the flexible operation unit
shall continue to be considered a TPPU and subject to the requirements
of this subpart.
(A) The product identified in (f)(10)(ii) of this section is not a
thermoplastic product; and
(B) The production of the product identified in (f)(10)(ii) of this
section is subject to another subpart of this part; and
(C) The owner or operator submits a notification to the
Administrator of the pending change in applicability.
(g) Storage vessel ownership determination. The owner or operator
shall follow the procedures specified in paragraphs (g)(1) through
(g)(7) of this section to
[[Page 225]]
determine to which process unit a storage vessel shall be assigned.
Paragraph (g)(8) of this section specifies when an owner or operator is
required to redetermine to which process unit a storage vessel is
assigned.
(1) If a storage vessel is already subject to another subpart of 40
CFR part 63 on September 12, 1996, said storage vessel shall be assigned
to the process unit subject to the other subpart.
(2) If a storage vessel is dedicated to a single process unit, the
storage vessel shall be assigned to that process unit.
(3) If a storage vessel is shared among process units, then the
storage vessel shall be assigned to that process unit located on the
same plant site as the storage vessel that has the greatest input into
or output from the storage vessel (i.e., said process unit has the
predominant use of the storage vessel).
(4) If predominant use cannot be determined for a storage vessel
that is shared among process units and if only one of those process
units is a TPPU subject to this subpart, the storage vessel shall be
assigned to said TPPU.
(5) If predominant use cannot be determined for a storage vessel
that is shared among process units and if more than one of the process
units are TPPUs that have different primary products and that are
subject to this subpart, then the owner or operator shall assign the
storage vessel to any one of the said TPPUs.
(6) If the predominant use of a storage vessel varies from year to
year, then predominant use shall be determined based on the utilization
that occurred during the year preceding September 12, 1996 or based on
the expected utilization for the 5 years following September 12, 1996
for existing affected sources, whichever is more representative of the
expected operations for said storage vessel, and based on the expected
utilization for the first 5 years after initial start-up for new
affected sources. The determination of predominant use shall be reported
in the Notification of Compliance Status, as required by
Sec. 63.1335(e)(5)(vi).
(7) Where a storage vessel is located at a major source that
includes one or more process units which place material into, or receive
materials from the storage vessel, but the storage vessel is located in
a tank farm (including a marine tank farm), the applicability of this
subpart shall be determined according to the provisions in paragraphs
(g)(7)(i) through (g)(7)(iv) of this section.
(i) The storage vessel may only be assigned to a process unit that
utilizes the storage vessel and does not have an intervening storage
vessel for that product (or raw material, as appropriate). With respect
to any process unit, an intervening storage vessel means a storage
vessel connected by hard-piping both to the process unit and to the
storage vessel in the tank farm so that product or raw material entering
or leaving the process unit flows into (or from) the intervening storage
vessel and does not flow directly into (or from) the storage vessel in
the tank farm.
(ii) If there is no process unit at the major source that meets the
criteria of paragraph (g)(7)(i) of this section with respect to a
storage vessel, this subpart does not apply to the storage vessel.
(iii) If there is only one process unit at the major source that
meets the criteria of paragraph (g)(7)(i) of this section with respect
to a storage vessel, the storage vessel shall be assigned to that
process unit.
(iv) If there are two or more process units at the major source that
meet the criteria of paragraph (g)(7)(i) of this section with respect to
a storage vessel, the storage vessel shall be assigned to one of those
process units according to the provisions of paragraphs (g)(3) through
(g)(6) of this section. The predominant use shall be determined among
only those process units that meet the criteria of paragraph (g)(7)(i)
of this section.
(8) If the storage vessel begins receiving material from (or sending
material to) a process unit that was not included in the initial
determination, or ceases to receive material from (or send material to)
a process unit, the owner or operator shall re-evaluate the
applicability of this subpart to the storage vessel.
(h) Recovery operations equipment ownership determination. The owner
or operator shall follow the procedures specified in paragraphs (h)(1)
through (h)(6)
[[Page 226]]
of this section to determine to which process unit recovery operations
equipment shall be assigned. Paragraph (h)(7) of this section specifies
when an owner or operator is required to redetermine to which process
unit the recovery operations equipment is assigned.
(1) If recovery operations equipment is already subject to another
subpart of 40 CFR part 63 on September 12, 1996, said recovery
operations equipment shall be assigned to the process unit subject to
the other subpart.
(2) If recovery operations equipment is dedicated to a single
process unit, the recovery operations equipment shall be assigned to
that process unit.
(3) If recovery operations equipment is shared among process units,
then the recovery operations equipment shall be assigned to that process
unit located on the same plant site as the recovery operations equipment
that has the greatest input into or output from the recovery operations
equipment (i.e., said process unit has the predominant use of the
recovery operations equipment).
(4) If predominant use cannot be determined for recovery operations
equipment that is shared among process units and if one of those process
units is a TPPU subject to this subpart, the recovery operations
equipment shall be assigned to said TPPU.
(5) If predominant use cannot be determined for recovery operations
equipment that is shared among process units and if more than one of the
process units are TPPUs that have different primary products and that
are subject to this subpart, then the owner or operator shall assign the
recovery operations equipment to any one of said TPPUs.
(6) If the predominant use of recovery operations equipment varies
from year to year, then predominant use shall be determined based on the
utilization that occurred during the year preceding September 12, 1996
or based on the expected utilization for the 5 years following September
12, 1996 for existing affected sources, whichever is the more
representative of the expected operations for said recovery operations
equipment, and based on the first 5 years after initial start-up for new
affected sources. The determination of predominant use shall be reported
in the Notification of Compliance Status, as required by
Sec. 63.1335(e)(5)(vii).
(7) If a piece of recovery operations equipment begins receiving
material from a process unit that was not included in the initial
determination, or ceases to receive material from a process unit that
was included in the initial determination, the owner or operator shall
reevaluate the applicability of this subpart to that recovery operations
equipment.
(i) Changes or additions to plant sites. The provisions of
paragraphs (i)(1) through (i)(4) of this section apply to owners or
operators that change or add to their plant site or affected source.
Paragraph (i)(5) of this section provides examples of what are and are
not considered process changes for purposes of this paragraph (i) of
this section. Paragraph (i)(6) of this section discusses reporting
requirements.
(1) Adding a TPPU to a plant site. The provisions of paragraphs
(i)(1)(i) and (i)(1)(ii) of this section apply to owners or operators
that add one or more TPPUs to a plant site.
(i) If a group of one or more TPPUs that produce the same primary
product is added to a plant site, the added group of one or more TPPUs
and associated equipment, as listed in paragraph (a)(4) of this section,
shall be a new affected source and shall comply with the requirements
for a new affected source in this subpart upon initial start-up or by
June 19, 2000, whichever is later, as provided in Sec. 63.6(b), except
that new affected sources whose primary product, as determined using the
procedures specified in paragraph (f) of this section, is poly(ethylene
terephthalate) (PET) shall be in compliance with Sec. 63.1331 upon
initial start-up or February 27, 2001, whichever is later, if the added
group of one or more TPPUs meets the criteria in either paragraph
(i)(1)(i)(A) or (i)(1)(i)(B) of this section, and the criteria in either
paragraph (i)(1)(i)(C) or (i)(1)(i)(D) of this section are met.
(A) The construction of the group of one or more TPPUs commenced
after March 29, 1995.
[[Page 227]]
(B) The construction or reconstruction, for process units that have
become TPPUs, commenced after March 29, 1995.
(C) The group of one or more TPPUs and associated equipment, as
listed in paragraph (a)(4) of this section, has the potential to emit 10
tons per year or more of any HAP or 25 tons per year or more of any
combination of HAP, and the primary product of the group of one or more
TPPUs is currently produced at the plant site as the primary product of
an affected source; or
(D) The primary product of the group of one or more TPPUs is not
currently produced at the plant site as the primary product of an
affected source and the plant site meets, or after the addition of the
group of one or more TPPUs and associated equipment, as listed in
paragraph (a)(4) of this section, will meet the definition of a major
source.
(ii) If a group of one or more TPPUs that produce the same primary
product is added to a plant site, and the group of one or more TPPUs
does not meet the criteria specified in paragraph (i)(1)(i) of this
section, and the plant site meets, or after the addition will meet, the
definition of a major source, the group of one or more TPPUs and
associated equipment, as listed in paragraph (a)(4) of this section,
shall comply with the requirements for an existing affected source in
this subpart upon initial start-up; by June 19, 2001; or by 6 months
after notifying the Administrator that a process unit has been
designated as a TPPU (in accordance with paragraph (f)(3)(iii) of this
section), whichever is later.
(2) Adding emission points or making process changes to existing
affected sources. The provisions of paragraphs (i)(2)(i) through
(i)(2)(ii) of this section apply to owners or operators that add
emission points or make process changes to an existing affected source.
(i) If any components are replaced at an existing affected source
such that the criteria specified in paragraphs (i)(2)(i)(A) through
(i)(2)(i)(B) of this section are met, the entire affected source shall
be a new affected source and shall comply with the requirements for a
new affected source upon initial start-up or by June 19, 2000, whichever
is later, as provided in Sec. 63.6(b), except that new affected sources
whose primary product is poly(ethylene terephthalate) (PET) shall be in
compliance with Sec. 63.1331 upon initial start-up or by February 27,
2001, whichever is later.
(A) The replacement of components meets the definition of
reconstruction in Sec. 63.1312(b); and
(B) Such reconstruction commenced after March 29, 1995.
(ii) If any components are replaced at an existing affected source
such that the criteria specified in paragraphs (i)(2)(i)(A) through
(i)(2)(i)(B) of this section are not met, and that replacement of
components creates one or more Group 1 emission points (i.e., either
newly created Group 1 emission points or emission points that change
group status from Group 2 to Group 1) or causes any other emission point
to be added (i.e., Group 2 emission points, equipment leak components
subject to Sec. 63.1331, continuous process vents subject to
Secs. 63.1316 through 63.1320, heat exchange systems subject to
Sec. 63.1328, and process contact cooling towers subject to
Sec. 63.1329), the resulting emission point(s) shall be subject to the
applicable requirements for an existing affected source. The resulting
emission points shall be in compliance by 120 days after the date of
initial start-up or by the appropriate compliance date specified in
Sec. 63.1311 (i.e., February 27, 1998 for most equipment leak components
subject to Sec. 63.1331, June 19, 2001 for most emission points other
than equipment leaks, and February 27, 2001 for process contact cooling
towers at sources that produce PET as the primary product), whichever is
later.
(iii) If an addition or process change (not including a process
change that solely replaces components) is made to an existing affected
source that creates one or more Group 1 emission points (i.e., either
newly created Group 1 emission points or emission points that change
group status from Group 2 to Group 1) or causes any other emission point
to be added (i.e., Group 2 emission points, equipment leak components
subject to Sec. 63.1331, continuous process vents subject to
Secs. 63.1316 through 63.1320, heat exchange systems subject to
Sec. 63.1328, and process contact cooling towers subject to
Sec. 63.1329), the
[[Page 228]]
resulting emission point(s) shall be subject to the applicable
requirements for an existing affected source. The resulting emission
point(s) shall be in compliance by 120 days after the date of initial
start-up or by the appropriate compliance date specified in Sec. 63.1311
(i.e., February 27, 1998 for most equipment leak components subject to
Sec. 63.1331, June 19, 2001 for most emission points other than
equipment leaks, and February 27, 2001 for process contact cooling
towers at sources that produce PET as their primary product), whichever
is later.
(iv) If any process change (not including a process change that
solely replaces components) is made to an existing affected source that
results in baseline emissions (i.e., emissions prior to applying
controls for purposes of complying with this subpart) from continuous
process vents in the collection of material recovery sections within the
affected source at an existing affected source producing PET using a
continuous dimethyl terephthalate process changing from less than or
equal to 0.12 kg organic HAP per Mg of product to greater than 0.12 kg
organic HAP per Mg of product, the continuous process vents shall be
subject to the applicable requirements for an existing affected source.
The resulting emission point(s) shall be in compliance by 120 days after
the date of initial start-up or by June 19, 2001, whichever is later.
(3) Existing affected source requirements for surge control vessels
and bottoms receivers that become subject to subpart H requirements. If
a process change or addition of an emission point causes a surge control
vessel or bottoms receiver to become subject to Sec. 63.170 under this
paragraph (i), the owner or operator shall be in compliance upon initial
start-up or by June 19, 2001, whichever is later.
(4) Existing affected source requirements for compressors that
become subject to the requirements of subpart H of this part. If a
process change or the addition of an emission point causes a compressor
to become subject to Sec. 63.164 under this paragraph (i), the owner or
operator shall be in compliance upon initial start-up or by the
compliance date for that compressor as specified in Sec. 63.1311(d)(1)
through (d)(4), whichever is later.
(5) Determining what are and are not process changes. For purposes
of paragraph (i) of this section, examples of process changes include,
but are not limited to, changes in feedstock type, or process catalyst
type, or the replacement, removal, or addition of recovery equipment, or
equipment changes that increase production capacity. For purposes of
paragraph (i) of this section, process changes do not include: Process
upsets, unintentional temporary process changes, and changes that do not
alter the equipment configuration and operating conditions.
(6) Reporting requirements for owners or operators that change or
add to their plant site or affected source. Owners or operators that
change or add to their plant site or affected source, as discussed in
paragraphs (i)(1) and (i)(2) of this section, shall submit a report as
specified in Sec. 63.1335(e)(7)(iv).
(j) Applicability of this subpart during periods of start-up,
shutdown, malfunction, or non-operation. Paragraphs (j)(1) through
(j)(4) of this section shall be followed during periods of start-up,
shutdown, malfunction, or non-operation of the affected source or any
part thereof.
(1) The emission limitations set forth in this subpart and the
emission limitations referred to in this subpart shall apply at all
times except during periods of non-operation of the affected source (or
specific portion thereof) resulting in cessation of the emissions to
which this subpart applies. The emission limitations of this subpart and
the emission limitations referred to in this subpart shall not apply
during periods of start-up, shutdown, or malfunction, except as provided
in paragraphs (j)(3) and (j)(4) of this section. During periods of
start-up, shutdown, or malfunction, the owner or operator shall follow
the applicable provisions of the start-up, shutdown, and malfunction
plan required by Sec. 63.1335(b)(1). However, if a start-up, shutdown,
malfunction, or period of non-operation of one portion of an affected
source does not affect the ability of a particular emission point to
comply with the emission limitations to which it is subject, then that
[[Page 229]]
emission point shall still be required to comply with the applicable
emission limitations of this subpart during the start-up, shutdown,
malfunction, or period of non-operation. For example, if there is an
overpressure in the reactor area, a storage vessel that is part of the
affected source would still be required to be controlled in accordance
with the emission limitations in Sec. 63.1314. Similarly, the degassing
of a storage vessel would not affect the ability of a batch process vent
to meet the emission limitations of Secs. 63.1321 through 63.1327.
(2) The emission limitations set forth in subpart H of this part, as
referred to in Sec. 63.1331, shall apply at all times except during
periods of non-operation of the affected source (or specific portion
thereof) in which the lines are drained and depressurized resulting in
cessation of the emissions to which Sec. 63.1331 applies, or during
periods of start-up, shutdown, malfunction, or process unit shutdown (as
defined in Sec. 63.161).
(3) The owner or operator shall not shut down items of equipment
that are required or utilized for compliance with this subpart during
periods of start-up, shutdown, or malfunction during times when
emissions (or, where applicable, wastewater streams or residuals) are
being routed to such items of equipment, if the shutdown would
contravene requirements of this subpart applicable to such items of
equipment. This paragraph (j)(3) does not apply if the item of equipment
is malfunctioning. This paragraph also does not apply if the owner or
operator shuts down the compliance equipment (other than monitoring
systems) to avoid damage due to a contemporaneous start-up, shutdown, or
malfunction of the affected source or portion thereof. If the owner or
operator has reason to believe that monitoring equipment would be
damaged due to a contemporaneous start-up, shutdown, or malfunction of
the affected source or portion thereof, the owner or operator shall
provide documentation supporting such a claim in the Precompliance
Report or in a supplement to the Precompliance Report, as provided in
Sec. 63.1335(e)(3). Once approved by the Administrator in accordance
with Sec. 63.1335(e)(3)(viii), the provision for ceasing to collect,
during a start-up, shutdown, or malfunction, monitoring data that would
otherwise be required by the provisions of this subpart must be
incorporated into the start-up, shutdown, malfunction plan for that
affected source, as stated in Sec. 63.1335(b)(1).
(4) During start-ups, shutdowns, and malfunctions when the emission
limitations of this subpart do not apply pursuant to paragraphs (j)(1)
through (j)(3) of this section, the owner or operator shall implement,
to the extent reasonably available, measures to prevent or minimize
excess emissions to the extent practical. For purposes of this
paragraph, the term ``excess emissions'' means emissions greater than
those allowed by the emissions limitation which would apply during
operational periods other than start-up, shutdown, and malfunction. The
measures to be taken shall be identified in the applicable start-up,
shutdown, and malfunction plan, and may include, but are not limited to,
air pollution control technologies, recovery technologies, work
practices, pollution prevention, monitoring, and/or changes in the
manner of operation of the affected source. Back-up control devices are
not required, but may be used if available.

operator may elect to comply either with the monitoring, recordkeeping
and reporting requirements of this subpart, or with the monitoring,
recordkeeping and reporting requirements in 40 CFR parts 264 and/or 265,
as described in this paragraph, which shall constitute compliance with
the monitoring, recordkeeping and reporting requirements of this
subpart. The owner or operator shall identify which option has been
selected in the Notification of Compliance Status required by
Sec. 63.1335(e)(5).
(n) Applicability of other requirements for heat exchange systems or

completion of required tasks (e.g., weekly, monthly, quarterly, annual),
unless specified otherwise in the section or paragraph
[[Page 233]]
that imposes the requirement, refer to the standard calendar periods.
(1) Notwithstanding time periods specified in this subpart for
completion of required tasks, such time periods may be changed by mutual
agreement between the owner or operator and the Administrator, as
specified in subpart A of this part (e.g., a period could begin on the
compliance date or another date, rather than on the first day of the
standard calendar period). For each time period that is changed by
agreement, the revised period shall remain in effect until it is
changed. A new request is not necessary for each recurring period.
(2) Where the period specified for compliance is a standard calendar
period, if the initial compliance date occurs after the beginning of the
period, compliance shall be required according to the schedule specified
in paragraphs (o)(2)(i) or (o)(2)(ii) of this section, as appropriate.

referred to as campaign plants or blocked operations.
Group 1 batch process vent means a batch process vent releasing
annual organic HAP emissions greater than the level specified in
Sec. 63.1323(d) and with a cutoff flow rate, calculated in accordance
with Sec. 63.1323(f), greater than or equal to the annual average batch
vent flow rate. Annual organic HAP emissions and annual average batch
vent flow rate are determined at the exit of the batch unit operation,
as described in Sec. 63.1323(a)(2). Annual organic HAP emissions are
determined as specified in Sec. 63.1323(b), and annual average batch
vent flow rate is determined as specified in Sec. 63.1323(e).

or greater determined by the procedures specified in
Sec. 63.115(d)(2)(v).
Heat exchange system means any cooling tower system or once-through
cooling water system (e.g., river or pond water) designed and intended
to operate to not allow contact between the cooling medium and process
fluid or gases (i.e., a noncontact system). A heat exchange system can
include more than one heat exchanger and can include recirculating or
once-through cooling systems.
Highest-HAP recipe for a product means the recipe of the product
with the highest total mass of HAP charged to the reactor during the
production of a single batch of product.
Initial start-up means the first time a new or reconstructed
affected source begins production of a thermoplastic product, or, for
equipment added or changed as described in Sec. 63.1310(i), the first
time the equipment is put into operation to produce a thermoplastic
product. Initial start-up does not include operation solely for testing
equipment. Initial start-up does not include subsequent start-ups of an
affected source or portion thereof following malfunctions or shutdowns
or following changes in product for flexible operation units or
following recharging of equipment in batch operation. Further, for
purposes of Sec. 63.1311 and Sec. 63.1331, initial start-up does not
include subsequent start-ups of affected sources or portions thereof
following malfunctions or process unit shutdowns.
Maintenance wastewater is defined in Sec. 63.101, except that the
term ``thermoplastic product process unit'' shall apply wherever the
term ``chemical manufacturing process unit'' is used. Further, the
generation of wastewater from the routine rinsing or washing of
equipment in batch operation between batches is not maintenance
wastewater, but is considered to be process wastewater, for the purposes
of this subpart.
Mass process means a polymerization process carried out through the
use of thermal energy. Mass processes do not utilize emulsifying or
suspending agents, but may utilize catalysts or other additives.
Material recovery section means, for PET plants, the equipment that
recovers by-product methanol from any process section for use, reuse, or
sale, or the equipment that separates materials containing by-product
methanol from any process section for off-site purification or treatment
with the intent to recover methanol for reuse. For polystyrene plants,
material recovery section means the equipment that recovers unreacted
styrene from any process section for use, reuse, or sale, or the
equipment that separates materials containing unreacted styrene from any
process section for off-site purification or treatment with the intent
to recover styrene for reuse. Equipment used to store recovered
materials (i.e., ethylene glycol, methanol, or styrene) is not included.
Equipment designed to recover or separate materials from the polymer
product is to be included in this process section, provided that at the
time of initial compliance some of the unreacted or by-product material
is recovered for return to the TPPU, or sale, or provided that some of
the separated material is sent for off-site purification or treatment
with the intent to recover the unreacted or by-product material for
reuse. Otherwise, such equipment is to be assigned to one of the other
process sections, as appropriate. If equipment is used to recover
unreacted or by-product material and return it directly to the same
piece of process equipment from which it was emitted, then that recovery
equipment is considered part of the process section that contains the
process equipment. On the other hand, if equipment is used to recover
unreacted or by-product material and return it to a different piece of
process equipment in the same process section, that recovery equipment
is considered part of a material recovery section. Equipment used for
the on-site recovery of ethylene glycol from PET plants, however, is not
included in the material recovery section; such equipment is to be
included in the polymerization reaction section. Equipment used for the
on-site recovery of both ethylene glycol and any other materials from
PET plants is not included in the material recovery section; this
[[Page 238]]
equipment is to be included in the polymerization reaction section. Such
equipment includes both contact and non-contact condensers removing
ethylene glycol from vapor streams coming out of polymerization vessels.

copolymer comprised of at least 50 percent bis-(2-hydroxyethyl)-
terephthalate by weight.
Polymerization reaction section means the equipment designed to
cause monomer(s) to react to form polymers, including equipment designed
primarily to cause the formation of short polymer chains (e.g.,
oligomers or low molecular weight polymers), but not including equipment
designed to prepare raw materials for polymerization (e.g.,
esterification vessels). For the purposes of these standards, the
polymerization reaction section begins with the equipment used to
transfer the materials from the raw materials preparation section and
ends with the last vessel in which polymerization occurs. Equipment used
for the on-site recovery of ethylene glycol from PET plants is included
in this process section, rather than in the material recovery process
section.
Polystyrene resin means a thermoplastic polymer or copolymer
comprised of at least 80 percent styrene or para-methylstyrene by

units, reactors, or other unit operations within the TPPU. Process vents
exclude pressure releases, gaseous streams routed to a fuel gas
system(s), and leaks from equipment regulated under Sec. 63.1331. A
gaseous emission stream is no longer considered to be a process vent
after the stream has been controlled and monitored in accordance with
the applicable provisions of this subpart.
Product means a polymer produced using the same monomers and varying
in additives (e.g., initiators, terminators, etc.); catalysts; or in the
relative proportions of monomers, that is manufactured by a process
unit. With respect to polymers, more than one recipe may be used to
produce the same product. As an example, styrene acrylonitrile resin and
methyl methacrylate butadiene styrene resin each represent a different
product. Product also means a chemical that is not a polymer, that is
manufactured by a process unit. By-products, isolated intermediates,
impurities, wastes, and trace contaminants are not considered products.
Raw materials preparation section means the equipment at a polymer
manufacturing plant designed to prepare raw materials, such as monomers
and solvents, for polymerization. For the purposes of the standards in
this subpart, this process section includes the equipment used to
transfer raw materials from storage and/or the equipment used to
transfer recovered material from the material recovery process sections
to the raw material preparation section, and ends with the last piece of
equipment that prepares the material for polymerization. The raw
materials preparation section may include equipment that is used to
purify, dry, or otherwise treat raw materials or raw and recovered
materials together; to activate catalysts; or to promote esterification
including the formation of some short polymer chains (oligomers). The
raw materials preparation section does not include equipment that is
designed primarily to accomplish the formation of oligomers, the
treatment of recovered materials alone, or the storage of raw or
recovered materials.
Recipe means a specific composition, from among the range of
possible compositions that may occur within a product, as defined in
this section. A recipe is determined by the proportions of monomers and,
if present, other reactants and additives that are used to make the
recipe. For example, acrylonitrile butadiene styrene latex resin (ABS
latex) without additives; ABS latex with an additive; and ABS latex with
different proportions of acrylonitrile to butadiene are all different
recipes of the same product, ABS latex.
Reconstruction means the addition of new components or the
replacement of existing components at an affected source or at a
previously unaffected stationary source that becomes an affected source
as a result of the change, to such an extent that:
(1) The fixed capital cost of the new components exceeds 50 percent
of the fixed capital cost that would be required to construct a
comparable affected new source; and
(2) It is technologically and economically feasible for the
reconstructed source to meet the provisions of this subpart.

monitoring, recordkeeping, or reporting requirements of this subpart,
recapture devices are considered recovery devices.
Recovery operations equipment means the equipment used to separate
the components of process streams. Recovery operations equipment
includes distillation units, condensers, etc. Equipment used for
wastewater treatment and recovery or recapture devices used as control
devices shall not be considered recovery operations equipment.
Residual is defined in Sec. 63.111, except that when the definition

maintenance, replacement of equipment, or repair, the cessation of
operation of an affected source, a TPPU(s) within an affected source, a
waste management unit or unit operation within an affected source, or
equipment required or used to comply with this subpart, or the emptying
or degassing of a storage vessel. For purposes of the wastewater
provisions of Sec. 63.1330, shutdown does not include the routine
rinsing or washing of equipment in batch operation between batches. For
purposes of the batch process vent provisions in Secs. 63.1321 through
63.1327, the cessation of equipment in batch operation is not a
shutdown, unless the equipment undergoes maintenance, is replaced, or is
repaired.
Solid state polymerization process means a unit operation which,
through the application of heat, furthers the polymerization (i.e.,
increases the intrinsic viscosity) of polymer chips.

initial start-up and operation solely for testing equipment. For both
continuous and batch processes, start-up does not include the recharging
of equipment in batch operation. For continuous processes, start-up
includes transitional conditions due to changes in product for flexible
operation units. For batch processes, start-up does not include
transitional conditions due to changes in product for flexible operation
units.
Steady-state conditions means that all variables (temperatures,
pressures, volumes, flow rates, etc.) in a process do not vary
significantly with time; minor fluctuations about constant mean values
may occur.

primarily of styrene and acrylonitrile monomer units.
Supplemental combustion air means the air that is added to a vent
stream after the vent stream leaves the unit operation. Air that is part
of the vent stream as a result of the nature of the unit operation is
not considered supplemental combustion air. Air required to operate
combustion device burner(s) is
[[Page 241]]
not considered supplemental combustion air. Air required to ensure the
proper operation of catalytic oxidizers, to include the intermittent
addition of air upstream of the catalyst bed to maintain a minimum
threshold flow rate through the catalyst bed or to avoid excessive
temperatures in the catalyst bed, is not considered to be supplemental
combustion air.
Suspension process means a polymerization process where the
monomer(s) is in a state of suspension, with the help of suspending

Sec. 63.149; storage vessels, as determined in Sec. 63.1310(g); and the
equipment that is subject to the equipment leak provisions as specified
in Sec. 63.1331. Utilities, lines and equipment not containing process
fluids, and other non-process lines, such as heating and cooling systems
which do not combine their materials with those in the processes they
serve, are not part of the thermoplastic product process unit. A
thermoplastic product process unit consists of more than one unit
operation.

reduction organic HAP associated with a continuous process vent stream,
based on vent stream flow rate, emission rate of organic HAP, net
heating value, and corrosion properties (whether or not the continuous
process vent stream contains halogenated compounds), as quantified by
the equations given under Sec. 63.115.
Vent stream, as used in reference to batch process vents, continuous
process vents, and aggregate batch vent streams, means the emissions
from one or more process vents.
Waste management unit is defined in Sec. 63.111, except that where
the definition in Sec. 63.111 uses the term ``chemical manufacturing
process unit,'' the term ``TPPU'' shall apply for purposes of this
subpart.
Wastewater means water that:
(1) Contains either:
