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, 2019), 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.
PAST PROVISIONS OF THE CODE
Provisions of the Code that are no longer in force and effect as of
the revision date stated on the cover of each volume are not carried.
Code users may find the text of provisions in effect on any given date
in the past by using the appropriate List of CFR Sections Affected
(LSA). For the convenience of the reader, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume. For changes to
the Code prior to the LSA listings at the end of the volume, consult
previous annual editions of the LSA. For changes to the Code prior to
2001, consult the List of CFR Sections Affected compilations, published
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.
``[RESERVED]'' TERMINOLOGY
The term ``[Reserved]'' is used as a place holder within the Code of
Federal Regulations. An agency may add regulatory information at a
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used
editorially to indicate that a portion of the CFR was left vacant and
not accidentally dropped due to a printing or computer error.
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.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed 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, 8601 Adelphi Road, College Park, MD 20740-6001,
or call 202-741-6010.
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 Authorities
and Rules. A list of CFR titles, chapters, subchapters, and parts and an
alphabetical list of agencies publishing in the CFR are also included in
this volume.
[[Page vii]]
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.
REPUBLICATION OF MATERIAL
There are no restrictions on the republication of material appearing
in the Code of Federal Regulations.

Authority: 42 U.S.C. 7401 et seq.
Source: 57 FR 61992, Dec. 29, 1992, unless otherwise noted.
Subpart A_General Provisions
Source: 59 FR 12430, Mar. 16, 1994, unless otherwise noted.
Sec. 63.1 Applicability.
(a) General. (1) Terms used throughout this part are defined in
Sec. 63.2 or in the Clean Air Act (Act) as amended in 1990, except that
individual subparts of this part may include specific definitions in
addition to or that supersede definitions in Sec. 63.2.
(2) This part contains national emission standards for hazardous air
pollutants (NESHAP) established pursuant to section 112 of the Act as
amended November 15, 1990. These standards regulate specific categories
of stationary sources that emit (or have the potential to emit) one or
more hazardous air pollutants listed in this part pursuant to section
112(b) of the Act. This section explains the applicability of such
standards to sources affected by them. The standards in this part are
independent of NESHAP contained in 40 CFR part 61. The NESHAP in part 61
promulgated by signature of the Administrator before November 15, 1990
(i.e., the date of enactment of the Clean Air Act Amendments of 1990)
remain in effect until they are amended, if appropriate, and added to
this part.
(3) No emission standard or other requirement established under this
part shall be interpreted, construed, or applied to diminish or replace
the requirements of a more stringent emission limitation or other
applicable requirement established by the Administrator pursuant to
other authority of the Act (section 111, part C or D or any other
authority of this Act), or a standard issued under State authority. The
Administrator may specify in a specific standard under this part that
facilities subject to other provisions under the Act need only comply
with the provisions of that standard.
(4)(i) Each relevant standard in this part 63 must identify
explicitly whether each provision in this subpart A is or is not
included in such relevant standard.
(ii) If a relevant part 63 standard incorporates the requirements of
40 CFR part 60, part 61 or other part 63 standards, the relevant part 63
standard must identify explicitly the applicability of each
corresponding part 60, part 61, or other part 63 subpart A (General)
provision.
(iii) The General Provisions in this subpart A do not apply to
regulations developed pursuant to section 112(r) of the amended Act,
unless otherwise specified in those regulations.
[[Page 12]]
(5) [Reserved]
(6) To obtain the most current list of categories of sources to be
regulated under section 112 of the Act, or to obtain the most recent
regulation promulgation schedule established pursuant to section 112(e)
of the Act, contact the Office of the Director, Emission Standards
Division, Office of Air Quality Planning and Standards, U.S. EPA (MD-
13), Research Triangle Park, North Carolina 27711.
(7)-(9) [Reserved]
(10) For the purposes of this part, time periods specified in days
shall be measured in calendar days, even if the word ``calendar'' is
absent, unless otherwise specified in an applicable requirement.
(11) For the purposes of this part, if an explicit postmark deadline
is not specified in an applicable requirement for the submittal of a
notification, application, test plan, report, or other written
communication to the Administrator, the owner or operator shall postmark
the submittal on or before the number of days specified in the
applicable requirement. For example, if a notification must be submitted
15 days before a particular event is scheduled to take place, the
notification shall be postmarked on or before 15 days preceding the
event; likewise, if a notification must be submitted 15 days after a
particular event takes place, the notification shall be postmarked on or
before 15 days following the end of the event. The use of reliable non-
Government mail carriers that provide indications of verifiable delivery
of information required to be submitted to the Administrator, similar to
the postmark provided by the U.S. Postal Service, or alternative means
of delivery agreed to by the permitting authority, is acceptable.
(12) Notwithstanding time periods or postmark deadlines specified in
this part for the submittal of information to the Administrator by an
owner or operator, or the review of such information by the
Administrator, such time periods or deadlines may be changed by mutual
agreement between the owner or operator and the Administrator.
Procedures governing the implementation of this provision are specified
in Sec. 63.9(i).
(b) Initial applicability determination for this part. (1) The
provisions of this part apply to the owner or operator of any stationary
source that--
(i) Emits or has the potential to emit any hazardous air pollutant
listed in or pursuant to section 112(b) of the Act; and
(ii) Is subject to any standard, limitation, prohibition, or other
federally enforceable requirement established pursuant to this part.
(2) [Reserved]
(3) An owner or operator of a stationary source who is in the
relevant source category and who determines that the source is not
subject to a relevant standard or other requirement established under
this part must keep a record as specified in Sec. 63.10(b)(3).
(c) Applicability of this part after a relevant standard has been
set under this part. (1) If a relevant standard has been established
under this part, the owner or operator of an affected source must comply
with the provisions of that standard and of this subpart as provided in
paragraph (a)(4) of this section.
(2) Except as provided in Sec. 63.10(b)(3), if a relevant standard
has been established under this part, the owner or operator of an
affected source may be required to obtain a title V permit from a
permitting authority in the State in which the source is located.
Emission standards promulgated in this part for area sources pursuant to
section 112(c)(3) of the Act will specify whether--
(i) States will have the option to exclude area sources affected by
that standard from the requirement to obtain a title V permit (i.e., the
standard will exempt the category of area sources altogether from the
permitting requirement);
(ii) States will have the option to defer permitting of area sources
in that category until the Administrator takes rulemaking action to
determine applicability of the permitting requirements; or
(iii) If a standard fails to specify what the permitting
requirements will be for area sources affected by such a standard, then
area sources that are subject to the standard will be subject
[[Page 13]]
to the requirement to obtain a title V permit without any deferral.
(3)-(4) [Reserved]
(5) If an area source that otherwise would be subject to an emission
standard or other requirement established under this part if it were a
major source subsequently increases its emissions of hazardous air
pollutants (or its potential to emit hazardous air pollutants) such that
the source is a major source that is subject to the emission standard or
other requirement, such source also shall be subject to the notification
requirements of this subpart.
(d) [Reserved]
(e) If the Administrator promulgates an emission standard under
section 112(d) or (h) of the Act that is applicable to a source subject
to an emission limitation by permit established under section 112(j) of
the Act, and the requirements under the section 112(j) emission
limitation are substantially as effective as the promulgated emission
standard, the owner or operator may request the permitting authority to
revise the source's title V permit to reflect that the emission
limitation in the permit satisfies the requirements of the promulgated
emission standard. The process by which the permitting authority
determines whether the section 112(j) emission limitation is
substantially as effective as the promulgated emission standard must
include, consistent with part 70 or 71 of this chapter, the opportunity
for full public, EPA, and affected State review (including the
opportunity for EPA's objection) prior to the permit revision being
finalized. A negative determination by the permitting authority
constitutes final action for purposes of review and appeal under the
applicable title V operating permit program.
[59 FR 12430, Mar. 16, 1994, as amended at 67 FR 16595, Apr. 5, 2002]
Sec. 63.2 Definitions.
The terms used in this part are defined in the Act or in this
section as follows:
Act means the Clean Air Act (42 U.S.C. 7401 et seq., as amended by
Pub. L. 101-549, 104 Stat. 2399).
Actual emissions is defined in subpart D of this part for the
purpose of granting a compliance extension for an early reduction of
hazardous air pollutants.
Administrator means the Administrator of the United States
Environmental Protection Agency or his or her authorized representative
(e.g., a State that has been delegated the authority to implement the
provisions of this part).
Affected source, for the purposes of this part, means the collection
of equipment, activities, or both within a single contiguous area and
under common control that is included in a section 112(c) source
category or subcategory for which a section 112(d) standard or other
relevant standard is established pursuant to section 112 of the Act.
Each relevant standard will define the ``affected source,'' as defined
in this paragraph unless a different definition is warranted based on a
published justification as to why this definition would result in
significant administrative, practical, or implementation problems and
why the different definition would resolve those problems. The term
``affected source,'' as used in this part, is separate and distinct from
any other use of that term in EPA regulations such as those implementing
title IV of the Act. Affected source may be defined differently for part
63 than affected facility and stationary source in parts 60 and 61,
respectively. This definition of ``affected source,'' and the procedures
for adopting an alternative definition of ``affected source,'' shall
apply to each section 112(d) standard for which the initial proposed
rule is signed by the Administrator after June 30, 2002.
Alternative emission limitation means conditions established
pursuant to sections 112(i)(5) or 112(i)(6) of the Act by the
Administrator or by a State with an approved permit program.
Alternative emission standard means an alternative means of emission
limitation that, after notice and opportunity for public comment, has
been demonstrated by an owner or operator to the Administrator's
satisfaction to achieve a reduction in emissions of any air pollutant at
least equivalent to the reduction in emissions of such pollutant
achieved under a relevant design,
[[Page 14]]
equipment, work practice, or operational emission standard, or
combination thereof, established under this part pursuant to section
112(h) of the Act.
Alternative test method means any method of sampling and analyzing
for an air pollutant that is not a test method in this chapter and that
has been demonstrated to the Administrator's satisfaction, using Method
301 in appendix A of this part, to produce results adequate for the
Administrator's determination that it may be used in place of a test
method specified in this part.
Approved permit program means a State permit program approved by the
Administrator as meeting the requirements of part 70 of this chapter or
a Federal permit program established in this chapter pursuant to title V
of the Act (42 U.S.C. 7661).
Area source means any stationary source of hazardous air pollutants
that is not a major source as defined in this part.
Commenced means, with respect to construction or reconstruction of
an affected source, that an owner or operator has undertaken a
continuous program of construction or reconstruction or that an owner or
operator has entered into a contractual obligation to undertake and
complete, within a reasonable time, a continuous program of construction
or reconstruction.
Compliance date means the date by which an affected source is
required to be in compliance with a relevant standard, limitation,
prohibition, or any federally enforceable requirement established by the
Administrator (or a State with an approved permit program) pursuant to
section 112 of the Act.
Compliance schedule means: (1) In the case of an affected source
that is in compliance with all applicable requirements established under
this part, a statement that the source will continue to comply with such
requirements; or
(2) In the case of an affected source that is required to comply
with applicable requirements by a future date, a statement that the
source will meet such requirements on a timely basis and, if required by
an applicable requirement, a detailed schedule of the dates by which
each step toward compliance will be reached; or
(3) In the case of an affected source not in compliance with all
applicable requirements established under this part, a schedule of
remedial measures, including an enforceable sequence of actions or
operations with milestones and a schedule for the submission of
certified progress reports, where applicable, leading to compliance with
a relevant standard, limitation, prohibition, or any federally
enforceable requirement established pursuant to section 112 of the Act
for which the affected source is not in compliance. This compliance
schedule shall resemble and be at least as stringent as that contained
in any judicial consent decree or administrative order to which the
source is subject. Any such schedule of compliance shall be supplemental
to, and shall not sanction noncompliance with, the applicable
requirements on which it is based.
Construction means the on-site fabrication, erection, or
installation of an affected source. Construction does not include the
removal of all equipment comprising an affected source from an existing
location and reinstallation of such equipment at a new location. The
owner or operator of an existing affected source that is relocated may
elect not to reinstall minor ancillary equipment including, but not
limited to, piping, ductwork, and valves. However, removal and
reinstallation of an affected source will be construed as reconstruction
if it satisfies the criteria for reconstruction as defined in this
section. The costs of replacing minor ancillary equipment must be
considered in determining whether the existing affected source is
reconstructed.
Continuous emission monitoring system (CEMS) means the total
equipment that may be required to meet the data acquisition and
availability requirements of this part, used to sample, condition (if
applicable), analyze, and provide a record of emissions.
Continuous monitoring system (CMS) is a comprehensive term that may
include, but is not limited to, continuous emission monitoring systems,
continuous opacity monitoring systems, continuous parameter monitoring
systems, or other manual or automatic
[[Page 15]]
monitoring that is used for demonstrating compliance with an applicable
regulation on a continuous basis as defined by the regulation.
Continuous opacity monitoring system (COMS) means a continuous
monitoring system that measures the opacity of emissions.
Continuous parameter monitoring system means the total equipment
that may be required to meet the data acquisition and availability
requirements of this part, used to sample, condition (if applicable),
analyze, and provide a record of process or control system parameters.
Effective date means:
(1) With regard to an emission standard established under this part,
the date of promulgation in the Federal Register of such standard; or
(2) With regard to an alternative emission limitation or equivalent
emission limitation determined by the Administrator (or a State with an
approved permit program), the date that the alternative emission
limitation or equivalent emission limitation becomes effective according
to the provisions of this part.
Emission standard means a national standard, limitation,
prohibition, or other regulation promulgated in a subpart of this part
pursuant to sections 112(d), 112(h), or 112(f) of the Act.
Emissions averaging is a way to comply with the emission limitations
specified in a relevant standard, whereby an affected source, if allowed
under a subpart of this part, may create emission credits by reducing
emissions from specific points to a level below that required by the
relevant standard, and those credits are used to offset emissions from
points that are not controlled to the level required by the relevant
standard.
EPA means the United States Environmental Protection Agency.
Equivalent emission limitation means any maximum achievable control
technology emission limitation or requirements which are applicable to a
major source of hazardous air pollutants and are adopted by the
Administrator (or a State with an approved permit program) on a case-by-
case basis, pursuant to section 112(g) or (j) of the Act.
Excess emissions and continuous monitoring system performance report
is a report that must be submitted periodically by an affected source in
order to provide data on its compliance with relevant emission limits,
operating parameters, and the performance of its continuous parameter
monitoring systems.
Existing source means any affected source that is not a new source.
Federally enforceable means all limitations and conditions that are
enforceable by the Administrator and citizens under the Act or that are
enforceable under other statutes administered by the Administrator.
Examples of federally enforceable limitations and conditions include,
but are not limited to:
(1) Emission standards, alternative emission standards, alternative
emission limitations, and equivalent emission limitations established
pursuant to section 112 of the Act as amended in 1990;
(2) New source performance standards established pursuant to section
111 of the Act, and emission standards established pursuant to section
112 of the Act before it was amended in 1990;
(3) All terms and conditions in a title V permit, including any
provisions that limit a source's potential to emit, unless expressly
designated as not federally enforceable;
(4) Limitations and conditions that are part of an approved State
Implementation Plan (SIP) or a Federal Implementation Plan (FIP);
(5) Limitations and conditions that are part of a Federal
construction permit issued under 40 CFR 52.21 or any construction permit
issued under regulations approved by the EPA in accordance with 40 CFR
part 51;
(6) Limitations and conditions that are part of an operating permit
where the permit and the permitting program pursuant to which it was
issued meet all of the following criteria:
(i) The operating permit program has been submitted to and approved
by EPA into a State implementation plan (SIP) under section 110 of the
CAA;
(ii) The SIP imposes a legal obligation that operating permit
holders adhere to the terms and limitations of such permits and provides
that permits
[[Page 16]]
which do not conform to the operating permit program requirements and
the requirements of EPA's underlying regulations may be deemed not
``federally enforceable'' by EPA;
(iii) The operating permit program requires that all emission
limitations, controls, and other requirements imposed by such permits
will be at least as stringent as any other applicable limitations and
requirements contained in the SIP or enforceable under the SIP, and that
the program may not issue permits that waive, or make less stringent,
any limitations or requirements contained in or issued pursuant to the
SIP, or that are otherwise ``federally enforceable'';
(iv) The limitations, controls, and requirements in the permit in
question are permanent, quantifiable, and otherwise enforceable as a
practical matter; and
(v) The permit in question was issued only after adequate and timely
notice and opportunity for comment for EPA and the public.
(7) Limitations and conditions in a State rule or program that has
been approved by the EPA under subpart E of this part for the purposes
of implementing and enforcing section 112; and
(8) Individual consent agreements that the EPA has legal authority
to create.
Fixed capital cost means the capital needed to provide all the
depreciable components of an existing source.
Force majeure means, for purposes of Sec. 63.7, an event that will
be or has been caused by circumstances beyond the control of the
affected facility, its contractors, or any entity controlled by the
affected facility that prevents the owner or operator from complying
with the regulatory requirement to conduct performance tests within the
specified timeframe despite the affected facility's best efforts to
fulfill the obligation. Examples of such events are acts of nature, acts
of war or terrorism, or equipment failure or safety hazard beyond the
control of the affected facility.
Fugitive emissions means those emissions from a stationary source
that could not reasonably pass through a stack, chimney, vent, or other
functionally equivalent opening. Under section 112 of the Act, all
fugitive emissions are to be considered in determining whether a
stationary source is a major source.
Hazardous air pollutant means any air pollutant listed in or
pursuant to section 112(b) of the Act.
Issuance of a part 70 permit will occur, if the State is the
permitting authority, in accordance with the requirements of part 70 of
this chapter and the applicable, approved State permit program. When the
EPA is the permitting authority, issuance of a title V permit occurs
immediately after the EPA takes final action on the final permit.
Major source means any stationary source or group of stationary
sources located within a contiguous area and under common control that
emits or has the potential to emit considering controls, in the
aggregate, 10 tons per year or more of any hazardous air pollutant or 25
tons per year or more of any combination of hazardous air pollutants,
unless the Administrator establishes a lesser quantity, or in the case
of radionuclides, different criteria from those specified in this
sentence.
Malfunction means any sudden, infrequent, and not reasonably
preventable failure of air pollution control and monitoring equipment,
process equipment, or a process to operate in a normal or usual manner
which causes, or has the potential to cause, the emission limitations in
an applicable standard to be exceeded. Failures that are caused in part
by poor maintenance or careless operation are not malfunctions.
Monitoring means the collection and use of measurement data or other
information to control the operation of a process or pollution control
device or to verify a work practice standard relative to assuring
compliance with applicable requirements. Monitoring is composed of four
elements:
(1) Indicator(s) of performance--the parameter or parameters you
measure or observe for demonstrating proper operation of the pollution
control measures or compliance with the applicable emissions limitation
or standard. Indicators of performance may include direct or predicted
emissions measurements (including opacity), operational
[[Page 17]]
parametric values that correspond to process or control device (and
capture system) efficiencies or emissions rates, and recorded findings
of inspection of work practice activities, materials tracking, or design
characteristics. Indicators may be expressed as a single maximum or
minimum value, a function of process variables (for example, within a
range of pressure drops), a particular operational or work practice
status (for example, a damper position, completion of a waste recovery
task, materials tracking), or an interdependency between two or among
more than two variables.
(2) Measurement techniques--the means by which you gather and record
information of or about the indicators of performance. The components of
the measurement technique include the detector type, location and
installation specifications, inspection procedures, and quality
assurance and quality control measures. Examples of measurement
techniques include continuous emission monitoring systems, continuous
opacity monitoring systems, continuous parametric monitoring systems,
and manual inspections that include making records of process conditions
or work practices.
(3) Monitoring frequency--the number of times you obtain and record
monitoring data over a specified time interval. Examples of monitoring
frequencies include at least four points equally spaced for each hour
for continuous emissions or parametric monitoring systems, at least
every 10 seconds for continuous opacity monitoring systems, and at least
once per operating day (or week, month, etc.) for work practice or
design inspections.
(4) Averaging time--the period over which you average and use data
to verify proper operation of the pollution control approach or
compliance with the emissions limitation or standard. Examples of
averaging time include a 3-hour average in units of the emissions
limitation, a 30-day rolling average emissions value, a daily average of
a control device operational parametric range, and an instantaneous
alarm.
New affected source means the collection of equipment, activities,
or both within a single contiguous area and under common control that is
included in a section 112(c) source category or subcategory that is
subject to a section 112(d) or other relevant standard for new sources.
This definition of ``new affected source,'' and the criteria to be
utilized in implementing it, shall apply to each section 112(d) standard
for which the initial proposed rule is signed by the Administrator after
June 30, 2002. Each relevant standard will define the term ``new
affected source,'' which will be the same as the ``affected source''
unless a different collection is warranted based on consideration of
factors including:
(1) Emission reduction impacts of controlling individual sources
versus groups of sources;
(2) Cost effectiveness of controlling individual equipment;
(3) Flexibility to accommodate common control strategies;
(4) Cost/benefits of emissions averaging;
(5) Incentives for pollution prevention;
(6) Feasibility and cost of controlling processes that share common
equipment (e.g., product recovery devices);
(7) Feasibility and cost of monitoring; and
(8) Other relevant factors.
New source means any affected source the construction or
reconstruction of which is commenced after the Administrator first
proposes a relevant emission standard under this part establishing an
emission standard applicable to such source.
One-hour period, unless otherwise defined in an applicable subpart,
means any 60-minute period commencing on the hour.
Opacity means the degree to which emissions reduce the transmission
of light and obscure the view of an object in the background. For
continuous opacity monitoring systems, opacity means the fraction of
incident light that is attenuated by an optical medium.
Owner or operator means any person who owns, leases, operates,
controls, or supervises a stationary source.
Performance audit means a procedure to analyze blind samples, the
content
[[Page 18]]
of which is known by the Administrator, simultaneously with the analysis
of performance test samples in order to provide a measure of test data
quality.
Performance evaluation means the conduct of relative accuracy
testing, calibration error testing, and other measurements used in
validating the continuous monitoring system data.
Performance test means the collection of data resulting from the
execution of a test method (usually three emission test runs) used to
demonstrate compliance with a relevant emission standard as specified in
the performance test section of the relevant standard.
Permit modification means a change to a title V permit as defined in
regulations codified in this chapter to implement title V of the Act (42
U.S.C. 7661).
Permit program means a comprehensive State operating permit system
established pursuant to title V of the Act (42 U.S.C. 7661) and
regulations codified in part 70 of this chapter and applicable State
regulations, or a comprehensive Federal operating permit system
established pursuant to title V of the Act and regulations codified in
this chapter.
Permit revision means any permit modification or administrative
permit amendment to a title V permit as defined in regulations codified
in this chapter to implement title V of the Act (42 U.S.C. 7661).
Permitting authority means: (1) The State air pollution control
agency, local agency, other State agency, or other agency authorized by
the Administrator to carry out a permit program under part 70 of this
chapter; or
(2) The Administrator, in the case of EPA-implemented permit
programs under title V of the Act (42 U.S.C. 7661).
Pollution Prevention means source reduction as defined under the
Pollution Prevention Act (42 U.S.C. 13101-13109). The definition is as
follows:
(1) Source reduction is any practice that:
(i) Reduces the amount of any hazardous substance, pollutant, or
contaminant entering any waste stream or otherwise released into the
environment (including fugitive emissions) prior to recycling,
treatment, or disposal; and
(ii) Reduces the hazards to public health and the environment
associated with the release of such substances, pollutants, or
contaminants.
(2) The term source reduction includes equipment or technology
modifications, process or procedure modifications, reformulation or
redesign of products, substitution of raw materials, and improvements in
housekeeping, maintenance, training, or inventory control.
(3) The term source reduction does not include any practice that
alters the physical, chemical, or biological characteristics or the
volume of a hazardous substance, pollutant, or contaminant through a
process or activity which itself is not integral to and necessary for
the production of a product or the providing of a service.
Potential to emit means the maximum capacity of a stationary source
to emit a pollutant under its physical and operational design. Any
physical or operational limitation on the capacity of the stationary
source to emit a pollutant, including air pollution control equipment
and restrictions on hours of operation or on the type or amount of
material combusted, stored, or processed, shall be treated as part of
its design if the limitation or the effect it would have on emissions is
federally enforceable.
Reconstruction, unless otherwise defined in a relevant standard,
means the replacement of components of an affected or a previously
nonaffected source 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 new source; and
(2) It is technologically and economically feasible for the
reconstructed source to meet the relevant standard(s) established by the
Administrator (or a State) pursuant to section 112 of the Act. Upon
reconstruction, an affected source, or a stationary source that becomes
an affected source, is subject to relevant standards for new sources,
including compliance dates, irrespective of any change in emissions of
hazardous air pollutants from that source.
[[Page 19]]

standard may include or consist of a design, equipment, work practice,
or operational requirement, or other measure, process, method, system,
or technique (including prohibition of emissions) that the Administrator
(or a State) establishes for new or existing sources to which such
standard or limitation applies. Every relevant standard established

Sec. 63.4 Prohibited activities and circumvention.
(a) Prohibited activities. (1) No owner or operator subject to the
provisions of this part must operate any affected source in violation of
the requirements of this part. Affected sources subject to and in
compliance with either an extension of compliance or an exemption from
compliance are not in violation of the requirements of this part. An
extension of compliance can be granted by the Administrator under this
part; by a State with an approved permit program; or by the President
under section 112(i)(4) of the Act.
(2) No owner or operator subject to the provisions of this part
shall fail to keep records, notify, report, or revise reports as
required under this part.
(3)-(5) [Reserved]
(b) Circumvention. No owner or operator subject to the provisions of
this part shall build, erect, install, or use any article, machine,
equipment, or process to conceal an emission that would otherwise
constitute noncompliance with a relevant standard. Such concealment
includes, but is not limited to--
(1) The use of diluents to achieve compliance with a relevant

applicability. The owner and operator must not use fragmentation or
phasing of reconstruction activities (i.e., intentionally dividing
reconstruction into multiple parts for purposes of avoiding new source
requirements) to avoid becoming subject to new source requirements.
[59 FR 12430, Mar. 16, 1994, as amended at 67 FR 16598, Apr. 5, 2002]
Sec. 63.5 Preconstruction review and notification requirements.
(a) Applicability. (1) This section implements the preconstruction
review requirements of section 112(i)(1). After the effective date of a
relevant standard, promulgated pursuant to section 112(d), (f), or (h)
of the Act, under this part, the preconstruction review requirements in
this section apply to the owner or operator of new affected sources and
reconstructed affected sources that are major-emitting as specified in
this section. New and reconstructed affected sources that commence
construction or reconstruction before the effective date of a relevant
standard are not subject to the preconstruction review requirements
specified in paragraphs (b)(3), (d), and (e) of this section.
(2) This section includes notification requirements for new affected
sources and reconstructed affected sources that are not major-emitting
affected sources and that are or become subject to a relevant
promulgated emission standard after the effective date of a relevant
standard promulgated under this part.
(b) Requirements for existing, newly constructed, and reconstructed
sources. (1) A new affected source for which construction commences
after proposal of a relevant standard is subject to relevant standards
for new affected sources, including compliance dates. An affected source
for which reconstruction commences after proposal of a relevant standard
is subject to relevant standards for new sources, including compliance
dates, irrespective of any change in emissions of hazardous air
pollutants from that source.
(2) [Reserved]
(3) After the effective date of any relevant standard promulgated by
the Administrator under this part, no person may, without obtaining
written approval in advance from the Administrator in accordance with
the procedures specified in paragraphs (d) and (e) of this section, do
any of the following:
[[Page 22]]
(i) Construct a new affected source that is major-emitting and
subject to such standard;
(ii) Reconstruct an affected source that is major-emitting and
subject to such standard; or
(iii) Reconstruct a major source such that the source becomes an
affected source that is major-emitting and subject to the standard.
(4) After the effective date of any relevant standard promulgated by
the Administrator under this part, an owner or operator who constructs a
new affected source that is not major-emitting or reconstructs an
affected source that is not major-emitting that is subject to such
standard, or reconstructs a source such that the source becomes an
affected source subject to the standard, must notify the Administrator
of the intended construction or reconstruction. The notification must be
submitted in accordance with the procedures in Sec. 63.9(b).
(5) [Reserved]
(6) After the effective date of any relevant standard promulgated by
the Administrator under this part, equipment added (or a process change)
to an affected source that is within the scope of the definition of
affected source under the relevant standard must be considered part of
the affected source and subject to all provisions of the relevant
standard established for that affected source.
(c) [Reserved]
(d) Application for approval of construction or reconstruction. The
provisions of this paragraph implement section 112(i)(1) of the Act.
(1) General application requirements. (i) An owner or operator who
is subject to the requirements of paragraph (b)(3) of this section must
submit to the Administrator an application for approval of the
construction or reconstruction. The application must be submitted as
soon as practicable before actual construction or reconstruction begins.
The application for approval of construction or reconstruction may be
used to fulfill the initial notification requirements of Sec.
63.9(b)(5). The owner or operator may submit the application for
approval well in advance of the date actual construction or
reconstruction begins in order to ensure a timely review by the
Administrator and that the planned date to begin will not be delayed.
(ii) A separate application shall be submitted for each construction
or reconstruction. Each application for approval of construction or
reconstruction shall include at a minimum:
(A) The applicant's name and address;
(B) A notification of intention to construct a new major affected
source or make any physical or operational change to a major affected
source that may meet or has been determined to meet the criteria for a
reconstruction, as defined in Sec. 63.2 or in the relevant standard;
(C) The address (i.e., physical location) or proposed address of the
source;
(D) An identification of the relevant standard that is the basis of
the application;

test methods specified in the relevant standard, or if actual emissions
data are not yet available, an estimate of the type and quantity of
hazardous air pollutants expected to be emitted by the source reported
in units and averaging times specified in the relevant standard. The
owner or operator may submit percent reduction information if a relevant
standard is established in terms of percent reduction. However,
operating parameters, such as flow rate, shall be included in the
submission to the extent that they demonstrate performance and
compliance; and
(I) [Reserved]
(J) Other information as specified in paragraphs (d)(2) and (d)(3)
of this section.
(iii) An owner or operator who submits estimates or preliminary
information in place of the actual emissions data and analysis required
in paragraphs (d)(1)(ii)(H) and (d)(2) of this
[[Page 23]]
section shall submit the actual, measured emissions data and other
correct information as soon as available but no later than with the
notification of compliance status required in Sec. 63.9(h) (see Sec.
63.9(h)(5)).
(2) Application for approval of construction. Each application for
approval of construction must include, in addition to the information
required in paragraph (d)(1)(ii) of this section, technical information
describing the proposed nature, size, design, operating design capacity,
and method of operation of the source, including an identification of
each type of emission point for each type of hazardous air pollutant
that is emitted (or could reasonably be anticipated to be emitted) and a
description of the planned air pollution control system (equipment or
method) for each emission point. The description of the equipment to be
used for the control of emissions must include each control device for
each hazardous air pollutant and the estimated control efficiency
(percent) for each control device. The description of the method to be
used for the control of emissions must include an estimated control
efficiency (percent) for that method. Such technical information must

approval of reconstruction shall include, in addition to the information
required in paragraph (d)(1)(ii) of this section--
(i) A brief description of the affected source and the components
that are to be replaced;
(ii) A description of present and proposed emission control systems
(i.e., equipment or methods). The description of the equipment to be
used for the control of emissions shall include each control device for
each hazardous air pollutant and the estimated control efficiency
(percent) for each control device. The description of the method to be
used for the control of emissions shall include an estimated control
efficiency (percent) for that method. Such technical information shall

technical or economic limitations affect the source's ability to comply
with the relevant standard and how they do so.
(vi) If in the application for approval of reconstruction the owner
or operator designates the affected source as a reconstructed source and
declares that there are no economic or technical limitations to prevent
the source from complying with all relevant standards or other
requirements, the owner or operator need not submit the information
required in paragraphs (d)(3)(iii) through (d)(3)(v) of this section.
(4) Additional information. The Administrator may request additional
relevant information after the submittal of an application for approval
of construction or reconstruction.
(e) Approval of construction or reconstruction. (1)(i) If the
Administrator determines that, if properly constructed, or
reconstructed, and operated, a new or existing source for which an
application under paragraph (d) of this section was submitted will not
cause emissions in violation of the relevant standard(s) and any other
federally enforceable requirements, the Administrator will approve the
construction or reconstruction.
(ii) In addition, in the case of reconstruction, the Administrator's
determination under this paragraph will be based on:
(A) The fixed capital cost of the replacements in comparison to the
fixed capital cost that would be required to construct a comparable
entirely new source;
(B) The estimated life of the source after the replacements compared
to the
[[Page 24]]
life of a comparable entirely new source;
(C) The extent to which the components being replaced cause or
contribute to the emissions from the source; and
(D) Any economic or technical limitations on compliance with
relevant standards that are inherent in the proposed replacements.
(2)(i) The Administrator will notify the owner or operator in
writing of approval or intention to deny approval of construction or
reconstruction within 60 calendar days after receipt of sufficient
information to evaluate an application submitted under paragraph (d) of
this section. The 60-day approval or denial period will begin after the
owner or operator has been notified in writing that his/her application
is complete. The Administrator will notify the owner or operator in
writing of the status of his/her application, that is, 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 is submitted.
(ii) When notifying the owner or operator that his/her application
is not complete, the Administrator will specify the information needed
to complete the application and provide notice of opportunity for the
applicant to present, in writing, within 30 calendar days after he/she
is notified of the incomplete application, additional information or
arguments to the Administrator to enable further action on the
application.
(3) Before denying any application for approval of construction or
reconstruction, the Administrator will notify the applicant of the
Administrator's intention to issue the denial together with--
(i) Notice of the information and findings on which the intended
denial is based; and

be in writing and will specify the grounds on which the denial is based.
The final determination will be made within 60 calendar days of
presentation of additional information or arguments (if the application
is complete), or within 60 calendar days after the final date specified
for presentation if no presentation is made.
(5) Neither the submission of an application for approval nor the
Administrator's approval of construction or reconstruction shall--
(i) Relieve an owner or operator of legal responsibility for
compliance with any applicable provisions of this part or with any other
applicable Federal, State, or local requirement; or
(ii) Prevent the Administrator from implementing or enforcing this
part or taking any other action under the Act.
(f) Approval of construction or reconstruction based on prior State
preconstruction review. (1) Preconstruction review procedures that a
State utilizes for other purposes may also be utilized for purposes of
this section if the procedures are substantially equivalent to those
specified in this section. The Administrator will approve an application
for construction or reconstruction specified in paragraphs (b)(3) and
(d) of this section if the owner or operator of a new affected source or
reconstructed affected source, who is subject to such requirement meets
the following conditions:
(i) The owner or operator of the new affected source or
reconstructed affected source has undergone a preconstruction review and
approval process in the State in which the source is (or would be)
located and has received a federally enforceable construction permit
that contains a finding that the source will meet the relevant
promulgated emission standard, if the source is properly built and
operated.
(ii) Provide a statement from the State or other evidence (such as
State regulations) that it considered the factors specified in paragraph
(e)(1) of this section.

request
[[Page 25]]
for approval of construction or reconstruction under this paragraph
(f)(2) no later than the application deadline specified in paragraph
(d)(1) of this section (see also Sec. 63.9(b)(2)). The owner or
operator must include in the request information sufficient for the
Administrator's determination. The Administrator will evaluate the owner
or operator's request in accordance with the procedures specified in
paragraph (e) of this section. The Administrator may request additional
relevant information after the submittal of a request for approval of
construction or reconstruction under this paragraph (f)(2).

this section; or
(ii) The President has granted an exemption from compliance with any
relevant standard in accordance with section 112(i)(4) of the Act.
(2) If an area source that otherwise would be subject to an emission
standard or other requirement established under this part if it were a
major source subsequently increases its emissions of hazardous air
pollutants (or its potential to emit hazardous air pollutants) such that
the source is a major source, such source shall be subject to the
relevant emission standard or other requirement.
(b) Compliance dates for new and reconstructed sources. (1) Except
as specified in paragraphs (b)(3) and (4) of this section, the owner or
operator of a new or reconstructed affected source for which
construction or reconstruction commences after proposal of a relevant
standard that has an initial startup before the effective date of a
relevant standard established under this part pursuant to section
112(d), (f), or (h) of the Act must comply with such standard not later
than the standard's effective date.
(2) Except as specified in paragraphs (b)(3) and (4) of this
section, the owner or operator of a new or reconstructed affected source
that has an initial startup after the effective date of a relevant
standard established under this part pursuant to section 112(d), (f), or
(h) of the Act must comply with such standard upon startup of the
source.
(3) The owner or operator of an affected source for which
construction or reconstruction is commenced after the proposal date of a
relevant standard established under this part pursuant to section
112(d), 112(f), or 112(h) of the Act but before the effective date (that
is, promulgation) of such standard shall comply with the relevant
emission standard not later than the date 3 years after the effective
date if:
(i) The promulgated standard (that is, the relevant standard) is
more stringent than the proposed standard; for purposes of this
paragraph, a finding that controls or compliance methods are ``more
stringent'' must include control technologies or performance criteria
and compliance or compliance assurance methods that are different but
are substantially equivalent to those required by the promulgated rule,
as determined by the Administrator (or his or her authorized
representative); and
(ii) The owner or operator complies with the standard as proposed
during the 3-year period immediately after the effective date.
(4) The owner or operator of an affected source for which
construction or reconstruction is commenced after the proposal date of a
relevant standard established pursuant to section 112(d) of the Act but
before the proposal date of a relevant standard established pursuant to
section 112(f) shall not be required to comply with the section 112(f)
emission standard until the date 10 years after the date construction or
reconstruction is commenced, except that, if the section 112(f) standard
is promulgated more than 10 years after construction or reconstruction
is commenced, the owner or operator must comply with the standard as
provided
[[Page 26]]
in paragraphs (b)(1) and (2) of this section.
(5) The owner or operator of a new source that is subject to the
compliance requirements of paragraph (b)(3) or (4) of this section must
notify the Administrator in accordance with Sec. 63.9(d)
(6) [Reserved]
(7) When an area source becomes a major source by the addition of
equipment or operations that meet the definition of new affected source
in the relevant standard, the portion of the existing facility that is a
new affected source must comply with all requirements of that standard
applicable to new sources. The source owner or operator must comply with
the relevant standard upon startup.
(c) Compliance dates for existing sources. (1) After the effective
date of a relevant standard established under this part pursuant to
section 112(d) or 112(h) of the Act, the owner or operator of an
existing source shall comply with such standard by the compliance date
established by the Administrator in the applicable subpart(s) of this
part. Except as otherwise provided for in section 112 of the Act, in no
case will the compliance date established for an existing source in an
applicable subpart of this part exceed 3 years after the effective date
of such standard.
(2) If an existing source is subject to a standard established under
this part pursuant to section 112(f) of the Act, the owner or operator
must comply with the standard by the date 90 days after the standard's
effective date, or by the date specified in an extension granted to the
source by the Administrator under paragraph (i)(4)(ii) of this section,
whichever is later.
(3)-(4) [Reserved]
(5) Except as provided in paragraph (b)(7) of this section, the
owner or operator of an area source that increases its emissions of (or
its potential to emit) hazardous air pollutants such that the source
becomes a major source shall be subject to relevant standards for
existing sources. Such sources must comply by the date specified in the
standards for existing area sources that become major sources. If no
such compliance date is specified in the standards, the source shall
have a period of time to comply with the relevant emission standard that
is equivalent to the compliance period specified in the relevant
standard for existing sources in existence at the time the standard
becomes effective.
(d) [Reserved]
(e) Operation and maintenance requirements. (1)(i) At all times,
including periods of startup, shutdown, and malfunction, the owner or
operator must operate and maintain any affected source, including
associated air pollution control equipment and monitoring equipment, in
a manner consistent with safety and good air pollution control practices
for minimizing emissions. During a period of startup, shutdown, or
malfunction, this general duty to minimize emissions requires that the
owner or operator reduce emissions from the affected source to the
greatest extent which is consistent with safety and good air pollution
control practices. The general duty to minimize emissions during a
period of startup, shutdown, or malfunction does not require the owner
or operator to achieve emission levels that would be required by the
applicable standard at other times if this is not consistent with safety
and good air pollution control practices, nor does it require the owner
or operator to make any further efforts to reduce emissions if levels
required by the applicable standard have been achieved. Determination of
whether such operation and maintenance procedures are being used will be
based on information available to the Administrator which may include,
but is not limited to, monitoring results, review of operation and
maintenance procedures (including the startup, shutdown, and malfunction
plan required in paragraph (e)(3) of this section), review of operation
and maintenance records, and inspection of the source.
(ii) Malfunctions must be corrected as soon as practicable after
their occurrence. To the extent that an unexpected event arises during a
startup, shutdown, or malfunction, an owner or operator must comply by
minimizing emissions during such a startup, shutdown, and malfunction
event consistent with safety and good air pollution control practices.
[[Page 27]]
(iii) Operation and maintenance requirements established pursuant to
section 112 of the Act are enforceable independent of emissions
limitations or other requirements in relevant standards.
(2) [Reserved]
(3) Startup, shutdown, and malfunction plan. (i) The owner or
operator of an affected source must develop a written startup, shutdown,
and malfunction plan that describes, in detail, procedures for operating
and maintaining the source during periods of startup, shutdown, and
malfunction; and a program of corrective action for malfunctioning
process, air pollution control, and monitoring equipment used to comply
with the relevant standard. The startup, shutdown, and malfunction plan
does not need to address any scenario that would not cause the source to
exceed an applicable emission limitation in the relevant standard. This
plan must be developed by the owner or operator by the source's
compliance date for that relevant standard. The purpose of the startup,
shutdown, and malfunction plan is to--
(A) Ensure that, at all times, the owner or operator operates and
maintains each affected source, including associated air pollution
control and monitoring equipment, in a manner which satisfies the
general duty to minimize emissions established by paragraph (e)(1)(i) of
this section;
(B) Ensure that owners or operators are prepared to correct
malfunctions as soon as practicable after their occurrence in order to
minimize excess emissions of hazardous air pollutants; and
(C) Reduce the reporting burden associated with periods of startup,
shutdown, and malfunction (including corrective action taken to restore
malfunctioning process and air pollution control equipment to its normal
or usual manner of operation).
(ii) [Reserved]
(iii) When actions taken by the owner or operator during a startup
or shutdown (and the startup or shutdown causes the source to exceed any
applicable emission limitation in the relevant emission standards), or
malfunction (including actions taken to correct a malfunction) are
consistent with the procedures specified in the affected source's
startup, shutdown, and malfunction plan, the owner or operator must keep
records for that event which demonstrate that the procedures specified
in the plan were followed. These records may take the form of a
``checklist,'' or other effective form of recordkeeping that confirms
conformance with the startup, shutdown, and malfunction plan and
describes the actions taken for that event. In addition, the owner or
operator must keep records of these events as specified in paragraph
63.10(b), including records of the occurrence and duration of each
startup or shutdown (if the startup or shutdown causes the source to
exceed any applicable emission limitation in the relevant emission
standards), or malfunction of operation and each malfunction of the air
pollution control and monitoring equipment. Furthermore, the owner or
operator shall confirm that actions taken during the relevant reporting
period during periods of startup, shutdown, and malfunction were
consistent with the affected source's startup, shutdown and malfunction
plan in the semiannual (or more frequent) startup, shutdown, and
malfunction report required in Sec. 63.10(d)(5).
(iv) If an action taken by the owner or operator during a startup,
shutdown, or malfunction (including an action taken to correct a
malfunction) is not consistent with the procedures specified in the
affected source's startup, shutdown, and malfunction plan, and the
source exceeds any applicable emission limitation in the relevant
emission standard, then the owner or operator must record the actions
taken for that event and must report such actions within 2 working days
after commencing actions inconsistent with the plan, followed by a
letter within 7 working days after the end of the event, in accordance
with Sec. 63.10(d)(5) (unless the owner or operator makes alternative
reporting arrangements, in advance, with the Administrator).
(v) The owner or operator must maintain at the affected source a
current startup, shutdown, and malfunction plan and must make the plan
available upon request for inspection and copying by the Administrator.
In addition,
[[Page 28]]
if the startup, shutdown, and malfunction plan is subsequently revised
as provided in paragraph (e)(3)(viii) of this section, the owner or
operator must maintain at the affected source each previous (i.e.,
superseded) version of the startup, shutdown, and malfunction plan, and
must make each such previous version available for inspection and
copying by the Administrator for a period of 5 years after revision of
the plan. If at any time after adoption of a startup, shutdown, and
malfunction plan the affected source ceases operation or is otherwise no
longer subject to the provisions of this part, the owner or operator
must retain a copy of the most recent plan for 5 years from the date the
source ceases operation or is no longer subject to this part and must
make the plan available upon request for inspection and copying by the
Administrator. The Administrator may at any time request in writing that
the owner or operator submit a copy of any startup, shutdown, and
malfunction plan (or a portion thereof) which is maintained at the
affected source or in the possession of the owner or operator. Upon
receipt of such a request, the owner or operator must promptly submit a
copy of the requested plan (or a portion thereof) to the Administrator.
The owner or operator may elect to submit the required copy of any
startup, shutdown, and malfunction plan to the Administrator in an
electronic format. If the owner or operator claims that any portion of
such a startup, shutdown, and malfunction plan is confidential business
information entitled to protection from disclosure under section 114(c)
of the Act or 40 CFR 2.301, the material which is claimed as
confidential must be clearly designated in the submission.
(vi) To satisfy the requirements of this section to develop a
startup, shutdown, and malfunction plan, the owner or operator may use
the affected source's standard operating procedures (SOP) manual, or an
Occupational Safety and Health Administration (OSHA) or other plan,
provided the alternative plans meet all the requirements of this section
and are made available for inspection or submitted when requested by the
Administrator.
(vii) Based on the results of a determination made under paragraph
(e)(1)(i) of this section, the Administrator may require that an owner
or operator of an affected source make changes to the startup, shutdown,
and malfunction plan for that source. The Administrator must require
appropriate revisions to a startup, shutdown, and malfunction plan, if
the Administrator finds that the plan:
(A) Does not address a startup, shutdown, or malfunction event that
has occurred;
(B) Fails to provide for the operation of the source (including
associated air pollution control and monitoring equipment) during a
startup, shutdown, or malfunction event in a manner consistent with the
general duty to minimize emissions established by paragraph (e)(1)(i) of
this section;
(C) Does not provide adequate procedures for correcting
malfunctioning process and/or air pollution control and monitoring
equipment as quickly as practicable; or
(D) Includes an event that does not meet the definition of startup,
shutdown, or malfunction listed in Sec. 63.2.
(viii) The owner or operator may periodically revise the startup,
shutdown, and malfunction plan for the affected source as necessary to
satisfy the requirements of this part or to reflect changes in equipment
or procedures at the affected source. Unless the permitting authority
provides otherwise, the owner or operator may make such revisions to the
startup, shutdown, and malfunction plan without prior approval by the
Administrator or the permitting authority. However, each such revision
to a startup, shutdown, and malfunction plan must be reported in the
semiannual report required by Sec. 63.10(d)(5). If the startup,
shutdown, and malfunction plan fails to address or inadequately
addresses an event that meets the characteristics of a malfunction but
was not included in the startup, shutdown, and malfunction plan at the
time the owner or operator developed the plan, the owner or operator
must revise the startup, shutdown, and malfunction plan within 45 days
after the event to include detailed
[[Page 29]]
procedures for operating and maintaining the source during similar
malfunction events and a program of corrective action for similar
malfunctions of process or air pollution control and monitoring
equipment. In the event that the owner or operator makes any revision to
the startup, shutdown, and malfunction plan which alters the scope of
the activities at the source which are deemed to be a startup, shutdown,
or malfunction, or otherwise modifies the applicability of any emission
limit, work practice requirement, or other requirement in a standard
established under this part, the revised plan shall not take effect
until after the owner or operator has provided a written notice
describing the revision to the permitting authority.
(ix) The title V permit for an affected source must require that the
owner or operator develop a startup, shutdown, and malfunction plan
which conforms to the provisions of this part, but may do so by citing
to the relevant subpart or subparagraphs of paragraph (e) of this
section. However, any revisions made to the startup, shutdown, and
malfunction plan in accordance with the procedures established by this
part shall not be deemed to constitute permit revisions under part 70 or
part 71 of this chapter and the elements of the startup, shutdown, and
malfunction plan shall not be considered an applicable requirement as
defined in Sec. 70.2 and Sec. 71.2 of this chapter. Moreover, none of
the procedures specified by the startup, shutdown, and malfunction plan
for an affected source shall be deemed to fall within the permit shield
provision in section 504(f) of the Act.
(f) Compliance with nonopacity emission standards--(1)
Applicability. The non-opacity emission standards set forth in this part
shall apply at all times except during periods of startup, shutdown, and
malfunction, and as otherwise specified in an applicable subpart. If a
startup, shutdown, or malfunction of one portion of an affected source
does not affect the ability of particular emission points within other
portions of the affected source to comply with the non-opacity emission
standards set forth in this part, then that emission point must still be
required to comply with the non-opacity emission standards and other
applicable requirements.
(2) Methods for determining compliance. (i) The Administrator will
determine compliance with nonopacity emission standards in this part
based on the results of performance tests conducted according to the
procedures in Sec. 63.7, unless otherwise specified in an applicable
subpart of this part.
(ii) The Administrator will determine compliance with nonopacity
emission standards in this part by evaluation of an owner or operator's
conformance with operation and maintenance requirements, including the
evaluation of monitoring data, as specified in Sec. 63.6(e) and
applicable subparts of this part.
(iii) If an affected source conducts performance testing at startup
to obtain an operating permit in the State in which the source is
located, the results of such testing may be used to demonstrate
compliance with a relevant standard if--
(A) The performance test was conducted within a reasonable amount of
time before an initial performance test is required to be conducted
under the relevant standard;
(B) The performance test was conducted under representative
operating conditions for the source;
(C) The performance test was conducted and the resulting data were
reduced using EPA-approved test methods and procedures, as specified in
Sec. 63.7(e) of this subpart; and
(D) The performance test was appropriately quality-assured, as
specified in Sec. 63.7(c).
(iv) The Administrator will determine compliance with design,
equipment, work practice, or operational emission standards in this part
by review of records, inspection of the source, and other procedures
specified in applicable subparts of this part.
(v) The Administrator will determine compliance with design,
equipment, work practice, or operational emission standards in this part
by evaluation of an owner or operator's conformance with operation and
maintenance requirements, as specified in paragraph (e) of this section
and applicable subparts of this part.
(3) Finding of compliance. The Administrator will make a finding
concerning
[[Page 30]]
an affected source's compliance with a non-opacity emission standard, as
specified in paragraphs (f)(1) and (2) of this section, upon obtaining
all the compliance information required by the relevant standard
(including the written reports of performance test results, monitoring
results, and other information, if applicable), and information
available to the Administrator pursuant to paragraph (e)(1)(i) of this
section.
(g) Use of an alternative nonopacity emission standard. (1) If, in
the Administrator's judgment, an owner or operator of an affected source
has established that an alternative means of emission limitation will
achieve a reduction in emissions of a hazardous air pollutant from an
affected source at least equivalent to the reduction in emissions of
that pollutant from that source achieved under any design, equipment,
work practice, or operational emission standard, or combination thereof,
established under this part pursuant to section 112(h) of the Act, the
Administrator will publish in the Federal Register a notice permitting
the use of the alternative emission standard for purposes of compliance
with the promulgated standard. Any Federal Register notice under this
paragraph shall be published only after the public is notified and given
the opportunity to comment. Such notice will restrict the permission to
the stationary source(s) or category(ies) of sources from which the
alternative emission standard will achieve equivalent emission
reductions. The Administrator will condition permission in such notice
on requirements to assure the proper operation and maintenance of
equipment and practices required for compliance with the alternative
emission standard and other requirements, including appropriate quality
assurance and quality control requirements, that are deemed necessary.
(2) An owner or operator requesting permission under this paragraph
shall, unless otherwise specified in an applicable subpart, submit a
proposed test plan or the results of testing and monitoring in
accordance with Sec. 63.7 and Sec. 63.8, a description of the
procedures followed in testing or monitoring, and a description of
pertinent conditions during testing or monitoring. Any testing or
monitoring conducted to request permission to use an alternative
nonopacity emission standard shall be appropriately quality assured and
quality controlled, as specified in Sec. 63.7 and Sec. 63.8.
(3) The Administrator may establish general procedures in an
applicable subpart that accomplish the requirements of paragraphs (g)(1)
and (g)(2) of this section.
(h) Compliance with opacity and visible emission standards--(1)
Applicability. The opacity and visible emission standards set forth in
this part must apply at all times except during periods of startup,
shutdown, and malfunction, and as otherwise specified in an applicable
subpart. If a startup, shutdown, or malfunction of one portion of an
affected source does not affect the ability of particular emission
points within other portions of the affected source to comply with the
opacity and visible emission standards set forth in this part, then that
emission point shall still be required to comply with the opacity and
visible emission standards and other applicable requirements.
(2) Methods for determining compliance. (i) The Administrator will
determine compliance with opacity and visible emission standards in this
part based on the results of the test method specified in an applicable
subpart. Whenever a continuous opacity monitoring system (COMS) is
required to be installed to determine compliance with numerical opacity
emission standards in this part, compliance with opacity emission
standards in this part shall be determined by using the results from the
COMS. Whenever an opacity emission test method is not specified,
compliance with opacity emission standards in this part shall be
determined by conducting observations in accordance with Test Method 9
in appendix A of part 60 of this chapter or the method specified in
paragraph (h)(7)(ii) of this section. Whenever a visible emission test
method is not specified, compliance with visible emission standards in
this part shall be determined by conducting observations in accordance
with Test Method 22 in appendix A of part 60 of this chapter.
(ii) [Reserved]
[[Page 31]]
(iii) If an affected source undergoes opacity or visible emission
testing at startup to obtain an operating permit in the State in which
the source is located, the results of such testing may be used to
demonstrate compliance with a relevant standard if--
(A) The opacity or visible emission test was conducted within a
reasonable amount of time before a performance test is required to be
conducted under the relevant standard;
(B) The opacity or visible emission test was conducted under
representative operating conditions for the source;
(C) The opacity or visible emission test was conducted and the
resulting data were reduced using EPA-approved test methods and
procedures, as specified in Sec. 63.7(e); and
(D) The opacity or visible emission test was appropriately quality-
assured, as specified in Sec. 63.7(c) of this section.
(3) [Reserved]
(4) Notification of opacity or visible emission observations. The
owner or operator of an affected source shall notify the Administrator
in writing of the anticipated date for conducting opacity or visible
emission observations in accordance with Sec. 63.9(f), if such
observations are required for the source by a relevant standard.
(5) Conduct of opacity or visible emission observations. When a
relevant standard under this part includes an opacity or visible
emission standard, the owner or operator of an affected source shall
comply with the following:
(i) For the purpose of demonstrating initial compliance, opacity or
visible emission observations shall be conducted concurrently with the
initial performance test required in Sec. 63.7 unless one of the
following conditions applies:
(A) If no performance test under Sec. 63.7 is required, opacity or
visible emission observations shall be conducted within 60 days after
achieving the maximum production rate at which a new or reconstructed
source will be operated, but not later than 120 days after initial
startup of the source, or within 120 days after the effective date of
the relevant standard in the case of new sources that start up before
the standard's effective date. If no performance test under Sec. 63.7
is required, opacity or visible emission observations shall be conducted
within 120 days after the compliance date for an existing or modified
source; or
(B) If visibility or other conditions prevent the opacity or visible
emission observations from being conducted concurrently with the initial
performance test required under Sec. 63.7, or within the time period
specified in paragraph (h)(5)(i)(A) of this section, the source's owner
or operator shall reschedule the opacity or visible emission
observations as soon after the initial performance test, or time period,
as possible, but not later than 30 days thereafter, and shall advise the
Administrator of the rescheduled date. The rescheduled opacity or
visible emission observations shall be conducted (to the extent
possible) under the same operating conditions that existed during the
initial performance test conducted under Sec. 63.7. The visible
emissions observer shall determine whether visibility or other
conditions prevent the opacity or visible emission observations from
being made concurrently with the initial performance test in accordance
with procedures contained in Test Method 9 or Test Method 22 in appendix
A of part 60 of this chapter.
(ii) For the purpose of demonstrating initial compliance, the
minimum total time of opacity observations shall be 3 hours (30 6-minute
averages) for the performance test or other required set of observations
(e.g., for fugitive-type emission sources subject only to an opacity
emission standard).
(iii) The owner or operator of an affected source to which an
opacity or visible emission standard in this part applies shall conduct
opacity or visible emission observations in accordance with the
provisions of this section, record the results of the evaluation of
emissions, and report to the Administrator the opacity or visible
emission results in accordance with the provisions of Sec. 63.10(d).
(iv) [Reserved]
(v) Opacity readings of portions of plumes that contain condensed,
uncombined water vapor shall not be used for purposes of determining
compliance with opacity emission standards.
[[Page 32]]
(6) Availability of records. The owner or operator of an affected
source shall make available, upon request by the Administrator, such
records that the Administrator deems necessary to determine the
conditions under which the visual observations were made and shall
provide evidence indicating proof of current visible observer emission
certification.
(7) Use of a continuous opacity monitoring system. (i) The owner or
operator of an affected source required to use a continuous opacity
monitoring system (COMS) shall record the monitoring data produced
during a performance test required under Sec. 63.7 and shall furnish
the Administrator a written report of the monitoring results in
accordance with the provisions of Sec. 63.10(e)(4).
(ii) Whenever an opacity emission test method has not been specified
in an applicable subpart, or an owner or operator of an affected source
is required to conduct Test Method 9 observations (see appendix A of
part 60 of this chapter), the owner or operator may submit, for
compliance purposes, COMS data results produced during any performance
test required under Sec. 63.7 in lieu of Method 9 data. If the owner or
operator elects to submit COMS data for compliance with the opacity
emission standard, he or she shall notify the Administrator of that
decision, in writing, simultaneously with the notification under Sec.
63.7(b) of the date the performance test is scheduled to begin. Once the
owner or operator of an affected source has notified the Administrator
to that effect, the COMS data results will be used to determine opacity
compliance during subsequent performance tests required under Sec.
63.7, unless the owner or operator notifies the Administrator in writing
to the contrary not later than with the notification under Sec. 63.7(b)
of the date the subsequent performance test is scheduled to begin.
(iii) For the purposes of determining compliance with the opacity
emission standard during a performance test required under Sec. 63.7
using COMS data, the COMS data shall be reduced to 6-minute averages
over the duration of the mass emission performance test.
(iv) The owner or operator of an affected source using a COMS for
compliance purposes is responsible for demonstrating that he/she has
complied with the performance evaluation requirements of Sec. 63.8(e),
that the COMS has been properly maintained, operated, and data quality-
assured, as specified in Sec. 63.8(c) and Sec. 63.8(d), and that the
resulting data have not been altered in any way.
(v) Except as provided in paragraph (h)(7)(ii) of this section, the
results of continuous monitoring by a COMS that indicate that the
opacity at the time visual observations were made was not in excess of
the emission standard are probative but not conclusive evidence of the
actual opacity of an emission, provided that the affected source proves
that, at the time of the alleged violation, the instrument used was
properly maintained, as specified in Sec. 63.8(c), and met Performance
Specification 1 in appendix B of part 60 of this chapter, and that the
resulting data have not been altered in any way.
(8) Finding of compliance. The Administrator will make a finding
concerning an affected source's compliance with an opacity or visible
emission standard upon obtaining all the compliance information required
by the relevant standard (including the written reports of the results
of the performance tests required by Sec. 63.7, the results of Test
Method 9 or another required opacity or visible emission test method,
the observer certification required by paragraph (h)(6) of this section,
and the continuous opacity monitoring system results, whichever is/are
applicable) and any information available to the Administrator needed to
determine whether proper operation and maintenance practices are being
used.
(9) Adjustment to an opacity emission standard. (i) If the
Administrator finds under paragraph (h)(8) of this section that an
affected source is in compliance with all relevant standards for which
initial performance tests were conducted under Sec. 63.7, but during
the time such performance tests were conducted fails to meet any
relevant opacity emission standard, the owner or operator of such source
may petition the Administrator to make appropriate adjustment to the
opacity emission
[[Page 33]]
standard for the affected source. Until the Administrator notifies the
owner or operator of the appropriate adjustment, the relevant opacity
emission standard remains applicable.
(ii) The Administrator may grant such a petition upon a
demonstration by the owner or operator that--
(A) The affected source and its associated air pollution control
equipment were operated and maintained in a manner to minimize the
opacity of emissions during the performance tests;
(B) The performance tests were performed under the conditions
established by the Administrator; and
(C) The affected source and its associated air pollution control
equipment were incapable of being adjusted or operated to meet the
relevant opacity emission standard.
(iii) The Administrator will establish an adjusted opacity emission
standard for the affected source meeting the above requirements at a
level at which the source will be able, as indicated by the performance
and opacity tests, to meet the opacity emission standard at all times
during which the source is meeting the mass or concentration emission
standard. The Administrator will promulgate the new opacity emission
standard in the Federal Register.
(iv) After the Administrator promulgates an adjusted opacity
emission standard for an affected source, the owner or operator of such
source shall be subject to the new opacity emission standard, and the
new opacity emission standard shall apply to such source during any
subsequent performance tests.
(i) Extension of compliance with emission standards. (1) Until an
extension of compliance has been granted by the Administrator (or a
State with an approved permit program) under this paragraph, the owner
or operator of an affected source subject to the requirements of this
section shall comply with all applicable requirements of this part.
(2) Extension of compliance for early reductions and other
reductions--(i) Early reductions. Pursuant to section 112(i)(5) of the
Act, if the owner or operator of an existing source demonstrates that
the source has achieved a reduction in emissions of hazardous air
pollutants in accordance with the provisions of subpart D of this part,
the Administrator (or the State with an approved permit program) will
grant the owner or operator an extension of compliance with specific
requirements of this part, as specified in subpart D.
(ii) Other reductions. Pursuant to section 112(i)(6) of the Act, if
the owner or operator of an existing source has installed best available
control technology (BACT) (as defined in section 169(3) of the Act) or
technology required to meet a lowest achievable emission rate (LAER) (as
defined in section 171 of the Act) prior to the promulgation of an
emission standard in this part applicable to such source and the same
pollutant (or stream of pollutants) controlled pursuant to the BACT or
LAER installation, the Administrator will grant the owner or operator an
extension of compliance with such emission standard that will apply
until the date 5 years after the date on which such installation was
achieved, as determined by the Administrator.
(3) Request for extension of compliance. Paragraphs (i)(4) through
(i)(7) of this section concern requests for an extension of compliance
with a relevant standard under this part (except requests for an
extension of compliance under paragraph (i)(2)(i) of this section will
be handled through procedures specified in subpart D of this part).
(4)(i)(A) The owner or operator of an existing source who is unable
to comply with a relevant standard established under this part pursuant
to section 112(d) of the Act may request that the Administrator (or a
State, when the State has an approved part 70 permit program and the
source is required to obtain a part 70 permit under that program, or a
State, when the State has been delegated the authority to implement and
enforce the emission standard for that source) grant an extension
allowing the source up to 1 additional year to comply with the standard,
if such additional period is necessary for the installation of controls.
An additional extension of up to 3 years may be added for mining waste
operations, if the 1-year extension of compliance is insufficient to dry
and
[[Page 34]]
cover mining waste in order to reduce emissions of any hazardous air
pollutant. The owner or operator of an affected source who has requested
an extension of compliance under this paragraph and who is otherwise
required to obtain a title V permit shall apply for such permit or apply
to have the source's title V permit revised to incorporate the
conditions of the extension of compliance. The conditions of an
extension of compliance granted under this paragraph will be
incorporated into the affected source's title V permit according to the
provisions of part 70 or Federal title V regulations in this chapter (42
U.S.C. 7661), whichever are applicable.
(B) Any request under this paragraph for an extension of compliance
with a relevant standard must be submitted in writing to the appropriate
authority no later than 120 days prior to the affected source's
compliance date (as specified in paragraphs (b) and (c) of this
section), except as provided for in paragraph (i)(4)(i)(C) of this
section. Nonfrivolous requests submitted under this paragraph will stay
the applicability of the rule as to the emission points in question
until such time as the request is granted or denied. A denial will be
effective as of the date of denial. Emission standards established under
this part may specify alternative dates for the submittal of requests
for an extension of compliance if alternatives are appropriate for the
source categories affected by those standards.
(C) An owner or operator may submit a compliance extension request
after the date specified in paragraph (i)(4)(i)(B) 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 must include, in addition to the information required in
paragraph (i)(6)(i) of this section, a statement of the reasons
additional time is needed and the date when the owner or operator first
learned of the problems. Nonfrivolous requests submitted under this
paragraph will stay the applicability of the rule as to the emission
points in question until such time as the request is granted or denied.
A denial will be effective as of the original compliance date.
(ii) The owner or operator of an existing source unable to comply
with a relevant standard established under this part pursuant to section
112(f) of the Act may request that the Administrator grant an extension
allowing the source up to 2 years after the standard's effective date to
comply with the standard. The Administrator may grant such an extension
if he/she finds that such additional period is necessary for the
installation of controls and that steps will be taken during the period
of the extension to assure that the health of persons will be protected
from imminent endangerment. Any request for an extension of compliance
with a relevant standard under this paragraph must be submitted in
writing to the Administrator not later than 90 calendar days after the
effective date of the relevant standard.
(5) The owner or operator of an existing source that has installed
BACT or technology required to meet LAER [as specified in paragraph
(i)(2)(ii) of this section] prior to the promulgation of a relevant
emission standard in this part may request that the Administrator grant
an extension allowing the source 5 years from the date on which such
installation was achieved, as determined by the Administrator, to comply
with the standard. Any request for an extension of compliance with a
relevant standard under this paragraph shall be submitted in writing to
the Administrator not later than 120 days after the promulgation date of
the standard. The Administrator may grant such an extension if he or she
finds that the installation of BACT or technology to meet LAER controls
the same pollutant (or stream of pollutants) that would be controlled at
that source by the relevant emission standard.
(6)(i) The request for a compliance extension under paragraph (i)(4)
of this section shall include the following information:
(A) A description of the controls to be installed to comply with the
standard;
(B) A compliance schedule, including the date by which each step
toward
[[Page 35]]
compliance will be reached. At a minimum, the list of dates shall
include:
(1) The date by which on-site construction, installation of emission
control equipment, or a process change is planned to be initiated; and
(2) The date by which final compliance is to be achieved.
(3) The date by which on-site construction, installation of emission
control equipment, or a process change is to be completed; and
(4) The date by which final compliance is to be achieved;
(C)-(D)
(ii) The request for a compliance extension under paragraph (i)(5)
of this section shall include all information needed to demonstrate to
the Administrator's satisfaction that the installation of BACT or
technology to meet LAER controls the same pollutant (or stream of
pollutants) that would be controlled at that source by the relevant
emission standard.
(7) Advice on requesting an extension of compliance may be obtained
from the Administrator (or the State with an approved permit program).
(8) Approval of request for extension of compliance. Paragraphs
(i)(9) through (i)(14) of this section concern approval of an extension
of compliance requested under paragraphs (i)(4) through (i)(6) of this
section.
(9) Based on the information provided in any request made under
paragraphs (i)(4) through (i)(6) of this section, or other information,
the Administrator (or the State with an approved permit program) may
grant an extension of compliance with an emission standard, as specified
in paragraphs (i)(4) and (i)(5) of this section.
(10) The extension will be in writing and will--
(i) Identify each affected source covered by the extension;
(ii) Specify the termination date of the extension;
(iii) Specify the dates by which steps toward compliance are to be
taken, if appropriate;
(iv) Specify other applicable requirements to which the compliance
extension applies (e.g., performance tests); and
(v)(A) Under paragraph (i)(4), specify any additional conditions
that the Administrator (or the State) deems necessary to assure
installation of the necessary controls and protection of the health of
persons during the extension period; or
(B) Under paragraph (i)(5), specify any additional conditions that
the Administrator deems necessary to assure the proper operation and
maintenance of the installed controls during the extension period.
(11) The owner or operator of an existing source that has been
granted an extension of compliance under paragraph (i)(10) of this
section may be required to submit to the Administrator (or the State
with an approved permit program) progress reports indicating whether the
steps toward compliance outlined in the compliance schedule have been
reached. The contents of the progress reports and the dates by which
they shall be submitted will be specified in the written extension of
compliance granted under paragraph (i)(10) of this section.
(12)(i) The Administrator (or the State with an approved permit
program) will notify the owner or operator in writing of approval or
intention to deny approval of a request for an extension of compliance
within 30 calendar days after receipt of sufficient information to
evaluate a request submitted under paragraph (i)(4)(i) or (i)(5) of this
section. The Administrator (or the State) will notify the owner or
operator in writing of the status of his/her application, that is,
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 is submitted. The 30-day approval or
denial period will begin after the owner or operator has been notified
in writing that his/her application is complete.
(ii) When notifying the owner or operator that his/her application
is not complete, the Administrator will specify the information needed
to complete the application and provide notice of opportunity for the
applicant to present, in writing, within 30 calendar
[[Page 36]]
days after he/she is notified of the incomplete application, additional
information or arguments to the Administrator to enable further action
on the application.
(iii) Before denying any request for an extension of compliance, the
Administrator (or the State with an approved permit program) will notify
the owner or operator in writing of the Administrator's (or the State's)
intention to issue the denial, together with--
(A) Notice of the information and findings on which the intended
denial is based; and
(B) Notice of opportunity for the owner or operator to present in
writing, within 15 calendar days after he/she is notified of the
intended denial, additional information or arguments to the
Administrator (or the State) before further action on the request.
(iv) The Administrator's final determination to deny any request for
an extension will be in writing and will set forth the specific grounds
on which the denial is based. The final determination will be made
within 30 calendar days after 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.
(13)(i) The Administrator will notify the owner or operator in
writing of approval or intention to deny approval of a request for an
extension of compliance within 30 calendar days after receipt of
sufficient information to evaluate a request submitted under paragraph
(i)(4)(ii) of this section. The 30-day approval or denial period will
begin after the owner or operator has been notified in writing that his/
her application is complete. The Administrator (or the State) will
notify the owner or operator in writing of the status of his/her
application, that is, whether the application contains sufficient
information to make a determination, within 15 calendar days after
receipt of the original application and within 15 calendar days after
receipt of any supplementary information that is submitted.
(ii) When notifying the owner or operator that his/her application
is not complete, the Administrator will specify the information needed
to complete the application and provide notice of opportunity for the
applicant to present, in writing, within 15 calendar days after he/she
is notified of the incomplete application, additional information or
arguments to the Administrator to enable further action on the
application.
(iii) Before denying any request for an extension of compliance, the
Administrator will notify the owner or operator in writing of the
Administrator's intention to issue the denial, together with--
(A) Notice of the information and findings on which the intended
denial is based; and
(B) Notice of opportunity for the owner or operator to present in
writing, within 15 calendar days after he/she is notified of the
intended denial, additional information or arguments to the
Administrator before further action on the request.
(iv) A final determination to deny any request for an extension will
be in writing and will set forth the specific grounds on which the
denial is based. The final determination will be made within 30 calendar
days after 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.
(14) The Administrator (or the State with an approved permit
program) may terminate an extension of compliance at an earlier date
than specified if any specification under paragraph (i)(10)(iii) or (iv)
of this section is not met. Upon a determination to terminate, the
Administrator will notify, in writing, the owner or operator of the
Administrator's determination to terminate, together with:
(i) Notice of the reason for termination; and
(ii) Notice of opportunity for the owner or operator to present in
writing, within 15 calendar days after he/she is notified of the
determination to terminate, additional information or arguments to the
Administrator before further action on the termination.
(iii) A final determination to terminate an extension of compliance
will be
[[Page 37]]
in writing and will set forth the specific grounds on which the
termination is based. The final determination will be made within 30
calendar days after presentation of additional information or arguments,
or within 30 calendar days after the final date specified for the
presentation if no presentation is made.
(15) [Reserved]
(16) The granting of an extension under this section shall not
abrogate the Administrator's authority under section 114 of the Act.
(j) Exemption from compliance with emission standards. The President
may exempt any stationary source from compliance with any relevant
standard established pursuant to section 112 of the Act for a period of
not more than 2 years if the President determines that the technology to
implement such standard is not available and that it is in the national
security interests of the United States to do so. An exemption under
this paragraph may be extended for 1 or more additional periods, each
period not to exceed 2 years.

FR 32600, May 30, 2003; 71 FR 20454, Apr. 20, 2006]
Sec. 63.7 Performance testing requirements.
(a) Applicability and performance test dates. (1) The applicability
of this section is set out in Sec. 63.1(a)(4).
(2) Except as provided in paragraph (a)(4) of this section, if
required to do performance testing by a relevant standard, and unless a
waiver of performance testing is obtained under this section or the
conditions of paragraph (c)(3)(ii)(B) of this section apply, the owner
or operator of the affected source must perform such tests within 180
days of the compliance date for such source.
(i)-(viii) [Reserved]
(ix) Except as provided in paragraph (a)(4) of this section, when an
emission standard promulgated under this part is more stringent than the
standard proposed (see Sec. 63.6(b)(3)), the owner or operator of a new
or reconstructed source subject to that standard for which construction
or reconstruction is commenced between the proposal and promulgation
dates of the standard shall comply with performance testing requirements
within 180 days after the standard's effective date, or within 180 days
after startup of the source, whichever is later. If the promulgated
standard is more stringent than the proposed standard, the owner or
operator may choose to demonstrate compliance with either the proposed
or the promulgated standard. If the owner or operator chooses to comply
with the proposed standard initially, the owner or operator shall
conduct a second performance test within 3 years and 180 days after the
effective date of the standard, or after startup of the source,
whichever is later, to demonstrate compliance with the promulgated
standard.
(3) The Administrator may require an owner or operator to conduct
performance tests at the affected source at any other time when the
action is authorized by section 114 of the Act.
(4) If a force majeure is about to occur, occurs, or has occurred
for which the affected owner or operator intends to assert a claim of
force majeure:
(i) The owner or operator shall notify the Administrator, in writing
as soon as practicable following the date the owner or operator first
knew, or through due diligence should have known that the event may
cause or caused a delay in testing beyond the regulatory deadline
specified in paragraph (a)(2) or (a)(3) of this section, or elsewhere in
this part, but the notification must occur before the performance test
deadline unless the initial force majeure or a subsequent force majeure
event delays the notice, and in such cases, the notification shall occur
as soon as practicable.
(ii) The owner or operator shall provide to the Administrator a
written description of the force majeure event and a rationale for
attributing the delay in testing beyond the regulatory deadline to the
force majeure; describe the measures taken or to be taken to minimize
the delay; and identify a date by which the owner or operator proposes
to conduct the performance test. The performance test shall be conducted
as soon as practicable after the force majeure occurs.
[[Page 38]]
(iii) The decision as to whether or not to grant an extension to the
performance test deadline is solely within the discretion of the
Administrator. The Administrator will notify the owner or operator in
writing of approval or disapproval of the request for an extension as
soon as practicable.
(iv) Until an extension of the performance test deadline has been
approved by the Administrator under paragraphs (a)(4)(i), (a)(4)(ii),
and (a)(4)(iii) of this section, the owner or operator of the affected
facility remains strictly subject to the requirements of this part.
(b) Notification of performance test. (1) The owner or operator of
an affected source must notify the Administrator in writing of his or
her intention to conduct a performance test at least 60 calendar days
before the performance test is initially scheduled to begin to allow the
Administrator, upon request, to review an approve the site-specific test
plan required under paragraph (c) of this section and to have an
observer present during the test.
(2) In the event the owner or operator is unable to conduct the
performance test on the date specified in the notification requirement
specified in paragraph (b)(1) of this section due to unforeseeable
circumstances beyond his or her control, the owner or operator must
notify the Administrator as soon as practicable and without delay prior
to the scheduled performance test date and specify the date when the
performance test is rescheduled. This notification of delay in
conducting the performance test shall not relieve the owner or operator
of legal responsibility for compliance with any other applicable
provisions of this part or with any other applicable Federal, State, or
local requirement, nor will it prevent the Administrator from
implementing or enforcing this part or taking any other action under the
Act.
(c) Quality assurance program. (1) The results of the quality
assurance program required in this paragraph will be considered by the
Administrator when he/she determines the validity of a performance test.
(2)(i) Submission of site-specific test plan. Before conducting a
required performance test, the owner or operator of an affected source
shall develop and, if requested by the Administrator, shall submit a
site-specific test plan to the Administrator for approval. The test plan
shall include a test program summary, the test schedule, data quality
objectives, and both an internal and external quality assurance (QA)
program. Data quality objectives are the pretest expectations of
precision, accuracy, and completeness of data.
(ii) The internal QA program shall include, at a minimum, the
activities planned by routine operators and analysts to provide an
assessment of test data precision; an example of internal QA is the
sampling and analysis of replicate samples.
(iii) The performance testing shall include a test method
performance audit (PA) during the performance test. The PAs consist of
blind audit samples supplied by an accredited audit sample provider and
analyzed during the performance test in order to provide a measure of
test data bias. Gaseous audit samples are designed to audit the
performance of the sampling system as well as the analytical system and
must be collected by the sampling system during the compliance test just
as the compliance samples are collected. If a liquid or solid audit
sample is designed to audit the sampling system, it must also be
collected by the sampling system during the compliance test. If multiple
sampling systems or sampling trains are used during the compliance test
for any of the test methods, the tester is only required to use one of
the sampling systems per method to collect the audit sample. The audit
sample must be analyzed by the same analyst using the same analytical
reagents and analytical system and at the same time as the compliance
samples. Retests are required when there is a failure to produce
acceptable results for an audit sample. However, if the audit results do
not affect the compliance or noncompliance status of the affected
facility, the compliance authority may waive the reanalysis requirement,
further audits, or retests and accept the results of the compliance
test. Acceptance of the test results shall constitute a waiver of the
reanalysis requirement,
[[Page 39]]
further audits, or retests. The compliance authority may also use the
audit sample failure and the compliance test results as evidence to
determine the compliance or noncompliance status of the affected
facility. A blind audit sample is a sample whose value is known only to
the sample provider and is not revealed to the tested facility until
after they report the measured value of the audit sample. For pollutants
that exist in the gas phase at ambient temperature, the audit sample
shall consist of an appropriate concentration of the pollutant in air or
nitrogen that can be introduced into the sampling system of the test
method at or near the same entry point as a sample from the emission
source. If no gas phase audit samples are available, an acceptable
alternative is a sample of the pollutant in the same matrix that would
be produced when the sample is recovered from the sampling system as
required by the test method. For samples that exist only in a liquid or
solid form at ambient temperature, the audit sample shall consist of an
appropriate concentration of the pollutant in the same matrix that would
be produced when the sample is recovered from the sampling system as
required by the test method. An accredited audit sample provider (AASP)
is an organization that has been accredited to prepare audit samples by
an independent, third party accrediting body.
(A) The source owner, operator, or representative of the tested
facility shall obtain an audit sample, if commercially available, from
an AASP for each test method used for regulatory compliance purposes. No
audit samples are required for the following test methods: Methods 3A
and 3C of appendix A-3 of part 60 of this chapter; Methods 6C, 7E, 9,
and 10 of appendix A-4 of part 60; Methods 18 and 19 of appendix A-6 of
part 60; Methods 20, 22, and 25A of appendix A-7 of part 60; Methods 30A
and 30B of appendix A-8 of part 60; and Methods 303, 318, 320, and 321
of appendix A of this part. If multiple sources at a single facility are
tested during a compliance test event, only one audit sample is required
for each method used during a compliance test. The compliance authority
responsible for the compliance test may waive the requirement to include
an audit sample if they believe that an audit sample is not necessary.
``Commercially available'' means that two or more independent AASPs have
blind audit samples available for purchase. If the source owner,
operator, or representative cannot find an audit sample for a specific
method, the owner, operator, or representative shall consult the EPA Web
site at the following URL, www.epa.gov/ttn/emc, to confirm whether there
is a source that can supply an audit sample for that method. If the EPA
Web site does not list an available audit sample at least 60 days prior
to the beginning of the compliance test, the source owner, operator, or
representative shall not be required to include an audit sample as part
of the quality assurance program for the compliance test. When ordering
an audit sample, the source owner, operator, or representative shall
give the sample provider an estimate for the concentration of each
pollutant that is emitted by the source or the estimated concentration
of each pollutant based on the permitted level and the name, address,
and phone number of the compliance authority. The source owner,
operator, or representative shall report the results for the audit
sample along with a summary of the emission test results for the audited
pollutant to the compliance authority and shall report the results of
the audit sample to the AASP. The source owner, operator, or
representative shall make both reports at the same time and in the same
manner or shall report to the compliance authority first and then report
to the AASP. If the method being audited is a method that allows the
samples to be analyzed in the field and the tester plans to analyze the
samples in the field, the tester may analyze the audit samples prior to
collecting the emission samples provided a representative of the
compliance authority is present at the testing site. The tester may
request, and the compliance authority may grant, a waiver to the
requirement that a representative of the compliance authority must be
present at the testing site during the field analysis of an audit
sample. The source owner, operator, or representative may report the
results of the audit sample
[[Page 40]]
to the compliance authority and then report the results of the audit
sample to the AASP prior to collecting any emission samples. The test
protocol and final test report shall document whether an audit sample
was ordered and utilized and the pass/fail results as applicable.
(B) An AASP shall have and shall prepare, analyze, and report the
true value of audit samples in accordance with a written technical
criteria document that describes how audit samples will be prepared and
distributed in a manner that will ensure the integrity of the audit
sample program. An acceptable technical criteria document shall contain
standard operating procedures for all of the following operations:
(1) Preparing the sample;
(2) Confirming the true concentration of the sample;
(3) Defining the acceptance limits for the results from a well
qualified tester. This procedure must use well established statistical
methods to analyze historical results from well qualified testers. The
acceptance limits shall be set so that there is 95 percent confidence
that 90 percent of well qualified labs will produce future results that
are within the acceptance limit range;
(4) Providing the opportunity for the compliance authority to
comment on the selected concentration level for an audit sample;
(5) Distributing the sample to the user in a manner that guarantees
that the true value of the sample is unknown to the user;
(6) Recording the measured concentration reported by the user and
determining if the measured value is within acceptable limits;
(7) Reporting the results from each audit sample in a timely manner
to the compliance authority and to the source owner, operator, or
representative by the AASP. The AASP shall make both reports at the same
time and in the same manner or shall report to the compliance authority
first and then report to the source owner, operator, or representative.
The results shall include the name of the facility tested, the date on
which the compliance test was conducted, the name of the company
performing the sample collection, the name of the company that analyzed
the compliance samples including the audit sample, the measured result
for the audit sample, and whether the testing company passed or failed
the audit. The AASP shall report the true value of the audit sample to
the compliance authority. The AASP may report the true value to the
source owner, operator, or representative if the AASP's operating plan
ensures that no laboratory will receive the same audit sample twice.
(8) Evaluating the acceptance limits of samples at least once every
two years to determine in consultation with the voluntary consensus
standard body if they should be changed.
(9) Maintaining a database, accessible to the compliance
authorities, of results from the audit that shall include the name of
the facility tested, the date on which the compliance test was
conducted, the name of the company performing the sample collection, the
name of the company that analyzed the compliance samples including the
audit sample, the measured result for the audit sample, the true value
of the audit sample, the acceptance range for the measured value, and
whether the testing company passed or failed the audit.
(C) The accrediting body shall have a written technical criteria
document that describes how it will ensure that the AASP is operating in
accordance with the AASP technical criteria document that describes how
audit samples are to be prepared and distributed. This document shall
contain standard operating procedures for all of the following
operations:
(1) Checking audit samples to confirm their true value as reported
by the AASP.
(2) Performing technical systems audits of the AASP's facilities and
operating procedures at least once every two years.
(3) Providing standards for use by the voluntary consensus standard
body to approve the accrediting body that will accredit the audit sample
providers.
(D) The technical criteria documents for the accredited sample
providers and the accrediting body shall be developed through a public
process guided by a voluntary consensus standards body
[[Page 41]]
(VCSB). The VCSB shall operate in accordance with the procedures and
requirements in the Office of Management and Budget Circular A-119. A
copy of Circular A-119 is available upon request by writing the Office
of Information and Regulatory Affairs, Office of Management and Budget,
725 17th Street, NW., Washington, DC 20503, by calling (202) 395-6880 or
downloading online at http://standards.gov/standards_gov/a119.cfm. The
VCSB shall approve all accrediting bodies. The Administrator will review
all technical criteria documents. If the technical criteria documents do
not meet the minimum technical requirements in paragraphs (c)(2)(iii)(B)
through (C) of this section, the technical criteria documents are not
acceptable and the proposed audit sample program is not capable of
producing audit samples of sufficient quality to be used in a compliance
test. All acceptable technical criteria documents shall be posted on the
EPA Web site at the following URL, http://www.epa.gov/ttn/emc.
(iv) The owner or operator of an affected source shall submit the
site-specific test plan to the Administrator upon the Administrator's
request at least 60 calendar days before the performance test is
scheduled to take place, that is, simultaneously with the notification
of intention to conduct a performance test required under paragraph (b)
of this section, or on a mutually agreed upon date.
(v) The Administrator may request additional relevant information
after the submittal of a site-specific test plan.
(3) Approval of site-specific test plan. (i) The Administrator will
notify the owner or operator of approval or intention to deny approval
of the site-specific test plan (if review of the site-specific test plan
is requested) within 30 calendar days after receipt of the original plan
and within 30 calendar days after receipt of any supplementary
information that is submitted under paragraph (c)(3)(i)(B) of this
section. Before disapproving any site-specific test plan, the
Administrator will notify the applicant of the Administrator's intention
to disapprove the plan together with--
(A) Notice of the information and findings on which the intended
disapproval is based; and
(B) Notice of opportunity for the owner or operator to present,
within 30 calendar days after he/she is notified of the intended
disapproval, additional information to the Administrator before final
action on the plan.
(ii) In the event that the Administrator fails to approve or
disapprove the site-specific test plan within the time period specified
in paragraph (c)(3)(i) of this section, the following conditions shall
apply:
(A) If the owner or operator intends to demonstrate compliance using
the test method(s) specified in the relevant standard or with only minor
changes to those tests methods (see paragraph (e)(2)(i) of this
section), the owner or operator must conduct the performance test within
the time specified in this section using the specified method(s);
(B) If the owner or operator intends to demonstrate compliance by
using an alternative to any test method specified in the relevant
standard, the owner or operator is authorized to conduct the performance
test using an alternative test method after the Administrator approves
the use of the alternative method when the Administrator approves the
site-specific test plan (if review of the site-specific test plan is
requested) or after the alternative method is approved (see paragraph
(f) of this section). However, the owner or operator is authorized to
conduct the performance test using an alternative method in the absence
of notification of approval 45 days after submission of the site-
specific test plan or request to use an alternative method. The owner or
operator is authorized to conduct the performance test within 60
calendar days after he/she is authorized to demonstrate compliance using
an alternative test method. Notwithstanding the requirements in the
preceding three sentences, the owner or operator may proceed to conduct
the performance test as required in this section (without the
Administrator's prior approval of the site-specific test plan) if he/she
subsequently chooses to
[[Page 42]]
use the specified testing and monitoring methods instead of an
alternative.
(iii) Neither the submission of a site-specific test plan for
approval, nor the Administrator's approval or disapproval of a plan, nor
the Administrator's failure to approve or disapprove a plan in a timely
manner shall--
(A) Relieve an owner or operator of legal responsibility for
compliance with any applicable provisions of this part or with any other
applicable Federal, State, or local requirement; or
(B) Prevent the Administrator from implementing or enforcing this
part or taking any other action under the Act.
(d) Performance testing facilities. If required to do performance
testing, the owner or operator of each new source and, at the request of
the Administrator, the owner or operator of each existing source, shall
provide performance testing facilities as follows:
(1) Sampling ports adequate for test methods applicable to such
source. This includes:
(i) Constructing the air pollution control system such that
volumetric flow rates and pollutant emission rates can be accurately
determined by applicable test methods and procedures; and
(ii) Providing a stack or duct free of cyclonic flow during
performance tests, as demonstrated by applicable test methods and
procedures;
(2) Safe sampling platform(s);
(3) Safe access to sampling platform(s);
(4) Utilities for sampling and testing equipment; and
(5) Any other facilities that the Administrator deems necessary for
safe and adequate testing of a source.
(e) Conduct of performance tests. (1) Performance tests shall be
conducted under such conditions as the Administrator specifies to the
owner or operator based on representative performance (i.e., performance
based on normal operating conditions) of the affected source. Operations
during periods of startup, shutdown, and malfunction shall not
constitute representative conditions for the purpose of a performance
test, nor shall emissions in excess of the level of the relevant
standard during periods of startup, shutdown, and malfunction be
considered a violation of the relevant standard unless otherwise
specified in the relevant standard or a determination of noncompliance
is made under Sec. 63.6(e). Upon request, the owner or operator shall
make available to the Administrator such records as may be necessary to
determine the conditions of performance tests.
(2) Performance tests shall be conducted and data shall be reduced
in accordance with the test methods and procedures set forth in this
section, in each relevant standard, and, if required, in applicable
appendices of parts 51, 60, 61, and 63 of this chapter unless the
Administrator--
(i) Specifies or approves, in specific cases, the use of a test
method with minor changes in methodology (see definition in Sec.
63.90(a)). Such changes may be approved in conjunction with approval of
the site-specific test plan (see paragraph (c) of this section); or
(ii) Approves the use of an intermediate or major change or
alternative to a test method (see definitions in Sec. 63.90(a)), the
results of which the Administrator has determined to be adequate for
indicating whether a specific affected source is in compliance; or
(iii) Approves shorter sampling times or smaller sample volumes when
necessitated by process variables or other factors; or
(iv) Waives the requirement for performance tests because the owner
or operator of an affected source has demonstrated by other means to the
Administrator's satisfaction that the affected source is in compliance
with the relevant standard.
(3) Unless otherwise specified in a relevant standard or test
method, each performance test shall consist of three separate runs using
the applicable test method. Each run shall be conducted for the time and
under the conditions specified in the relevant standard. For the purpose
of determining compliance with a relevant standard, the arithmetic mean
of the results of the three runs shall apply. Upon receiving approval
from the Administrator, results of a test run may be replaced with
results of an additional test run in the event that--
(i) A sample is accidentally lost after the testing team leaves the
site; or
[[Page 43]]
(ii) Conditions occur in which one of the three runs must be
discontinued because of forced shutdown; or
(iii) Extreme meteorological conditions occur; or
(iv) Other circumstances occur that are beyond the owner or
operator's control.
(4) Nothing in paragraphs (e)(1) through (e)(3) of this section
shall be construed to abrogate the Administrator's authority to require
testing under section 114 of the Act.
(f) Use of an alternative test method--(1)General. Until authorized
to use an intermediate or major change or alternative to a test method,
the owner or operator of an affected source remains subject to the
requirements of this section and the relevant standard.
(2) The owner or operator of an affected source required to do
performance testing by a relevant standard may use an alternative test
method from that specified in the standard provided that the owner or
operator--
(i) Notifies the Administrator of his or her intention to use an
alternative test method at least 60 days before the performance test is
scheduled to begin;
(ii) Uses Method 301 in appendix A of this part to validate the
alternative test method. This may include the use of specific procedures
of Method 301 if use of such procedures are sufficient to validate the
alternative test method; and
(iii) Submits the results of the Method 301 validation process along
with the notification of intention and the justification for not using
the specified test method. The owner or operator may submit the
information required in this paragraph well in advance of the deadline
specified in paragraph (f)(2)(i) of this section to ensure a timely
review by the Administrator in order to meet the performance test date
specified in this section or the relevant standard.
(3) The Administrator will determine whether the owner or operator's
validation of the proposed alternative test method is adequate and issue
an approval or disapproval of the alternative test method. If the owner
or operator intends to demonstrate compliance by using an alternative to
any test method specified in the relevant standard, the owner or
operator is authorized to conduct the performance test using an
alternative test method after the Administrator approves the use of the
alternative method. However, the owner or operator is authorized to
conduct the performance test using an alternative method in the absence
of notification of approval/disapproval 45 days after submission of the
request to use an alternative method and the request satisfies the
requirements in paragraph (f)(2) of this section. The owner or operator
is authorized to conduct the performance test within 60 calendar days
after he/she is authorized to demonstrate compliance using an
alternative test method. Notwithstanding the requirements in the
preceding three sentences, the owner or operator may proceed to conduct
the performance test as required in this section (without the
Administrator's prior approval of the site-specific test plan) if he/she
subsequently chooses to use the specified testing and monitoring methods
instead of an alternative.
(4) If the Administrator finds reasonable grounds to dispute the
results obtained by an alternative test method for the purposes of
demonstrating compliance with a relevant standard, the Administrator may
require the use of a test method specified in a relevant standard.
(5) If the owner or operator uses an alternative test method for an
affected source during a required performance test, the owner or
operator of such source shall continue to use the alternative test
method for subsequent performance tests at that affected source until he
or she receives approval from the Administrator to use another test
method as allowed under Sec. 63.7(f).
(6) Neither the validation and approval process nor the failure to
validate an alternative test method shall abrogate the owner or
operator's responsibility to comply with the requirements of this part.
(g) Data analysis, recordkeeping, and reporting. (1) Unless
otherwise specified in a relevant standard or test method, or as
otherwise approved by the Administrator in writing, results of a
performance test shall include the analysis of samples, determination of
emissions, and raw data. A performance
[[Page 44]]
test is ``completed'' when field sample collection is terminated. The
owner or operator of an affected source shall report the results of the
performance test to the Administrator before the close of business on
the 60th day following the completion of the performance test, unless
specified otherwise in a relevant standard or as approved otherwise in
writing by the Administrator (see Sec. 63.9(i)). The results of the
performance test shall be submitted as part of the notification of
compliance status required under Sec. 63.9(h). Before a title V permit
has been issued to the owner or operator of an affected source, the
owner or operator shall send the results of the performance test to the
Administrator. After a title V permit has been issued to the owner or
operator of an affected source, the owner or operator shall send the
results of the performance test to the appropriate permitting authority.
(2) Contents of a performance test, CMS performance evaluation, or
CMS quality assurance test report (electronic or paper submitted copy).
Unless otherwise specified in a relevant standard, test method, CMS
performance specification, or quality assurance requirement for a CMS,
or as otherwise approved by the Administrator in writing, the report
shall include the elements identified in paragraphs (g)(2)(i) through
(vi) of this section.
(i) General identification information for the facility including a
mailing address, the physical address, the owner or operator or
responsible official (where applicable) and his/her email address, and
the appropriate Federal Registry System (FRS) number for the facility.
(ii) Purpose of the test including the applicable regulation
requiring the test, the pollutant(s) and other parameters being
measured, the applicable emission standard, and any process parameter
component, and a brief process description.
(iii) Description of the emission unit tested including fuel burned,
control devices, and vent characteristics; the appropriate source
classification code (SCC); the permitted maximum process rate (where
applicable); and the sampling location.
(iv) Description of sampling and analysis procedures used and any
modifications to standard procedures, quality assurance procedures and
results, record of process operating conditions that demonstrate the
applicable test conditions are met, and values for any operating
parameters for which limits were being set during the test.
(v) Where a test method, CEMS, PEMS, or COMS performance
specification, or on-going quality assurance requirement for a CEMS,
PEMS, or COMS requires you record or report, the following shall be
included in your report: Record of preparation of standards, record of
calibrations, raw data sheets for field sampling, raw data sheets for
field and laboratory analyses, chain-of-custody documentation, and
example calculations for reported results.
(vi) Identification of the company conducting the performance test
including the primary office address, telephone number, and the contact
for this test including his/her email address.
(3) For a minimum of 5 years after a performance test is conducted,
the owner or operator shall retain and make available, upon request, for
inspection by the Administrator the records or results of such
performance test and other data needed to determine emissions from an
affected source.
(h) Waiver of performance tests. (1) Until a waiver of a performance
testing requirement has been granted by the Administrator under this
paragraph, the owner or operator of an affected source remains subject
to the requirements of this section.
(2) Individual performance tests may be waived upon written
application to the Administrator if, in the Administrator's judgment,
the source is meeting the relevant standard(s) on a continuous basis, or
the source is being operated under an extension of compliance, or the
owner or operator has requested an extension of compliance and the
Administrator is still considering that request.
(3) Request to waive a performance test. (i) If a request is made
for an extension
[[Page 45]]
of compliance under Sec. 63.6(i), the application for a waiver of an
initial performance test shall accompany the information required for
the request for an extension of compliance. If no extension of
compliance is requested or if the owner or operator has requested an
extension of compliance and the Administrator is still considering that
request, the application for a waiver of an initial performance test
shall be submitted at least 60 days before the performance test if the
site-specific test plan under paragraph (c) of this section is not
submitted.
(ii) If an application for a waiver of a subsequent performance test
is made, the application may accompany any required compliance progress
report, compliance status report, or excess emissions and continuous
monitoring system performance report [such as those required under Sec.
63.6(i), Sec. 63.9(h), and Sec. 63.10(e) or specified in a relevant
standard or in the source's title V permit], but it shall be submitted
at least 60 days before the performance test if the site-specific test
plan required under paragraph (c) of this section is not submitted.
(iii) Any application for a waiver of a performance test shall
include information justifying the owner or operator's request for a
waiver, such as the technical or economic infeasibility, or the
impracticality, of the affected source performing the required test.
(4) Approval of request to waive performance test. The Administrator
will approve or deny a request for a waiver of a performance test made
under paragraph (h)(3) of this section when he/she--
(i) Approves or denies an extension of compliance under Sec.
63.6(i)(8); or
(ii) Approves or disapproves a site-specific test plan under Sec.
63.7(c)(3); or
(iii) Makes a determination of compliance following the submission
of a required compliance status report or excess emissions and
continuous monitoring systems performance report; or
(iv) Makes a determination of suitable progress towards compliance
following the submission of a compliance progress report, whichever is
applicable.
(5) Approval of any waiver granted under this section shall not
abrogate the Administrator's authority under the Act or in any way
prohibit the Administrator from later canceling the waiver. The
cancellation will be made only after notice is given to the owner or
operator of the affected source.

Sec. 63.8 Monitoring requirements.
(a) Applicability. (1) The applicability of this section is set out
in Sec. 63.1(a)(4).
(2) For the purposes of this part, all CMS required under relevant
standards shall be subject to the provisions of this section upon
promulgation of performance specifications for CMS as specified in the
relevant standard or otherwise by the Administrator.
(3) [Reserved]
(4) Additional monitoring requirements for control devices used to
comply with provisions in relevant standards of this part are specified
in Sec. 63.11.
(b) Conduct of monitoring. (1) Monitoring shall be conducted as set
forth in this section and the relevant standard(s) unless the
Administrator--
(i) Specifies or approves the use of minor changes in methodology
for the specified monitoring requirements and procedures (see Sec.
63.90(a) for definition); or
(ii) Approves the use of an intermediate or major change or
alternative to any monitoring requirements or procedures (see Sec.
63.90(a) for definition).
(iii) Owners or operators with flares subject to Sec. 63.11(b) are
not subject to the requirements of this section unless otherwise
specified in the relevant standard.
(2)(i) When the emissions from two or more affected sources are
combined before being released to the atmosphere, the owner or operator
may install an applicable CMS for each emission stream or for the
combined emissions streams, provided the monitoring is sufficient to
demonstrate compliance with the relevant standard.
(ii) If the relevant standard is a mass emission standard and the
emissions from one affected source are released to the atmosphere
through more than one point, the owner or operator must
[[Page 46]]
install an applicable CMS at each emission point unless the installation
of fewer systems is--
(A) Approved by the Administrator; or
(B) Provided for in a relevant standard (e.g., instead of requiring
that a CMS be installed at each emission point before the effluents from
those points are channeled to a common control device, the standard
specifies that only one CMS is required to be installed at the vent of
the control device).
(3) When more than one CMS is used to measure the emissions from one
affected source (e.g., multiple breechings, multiple outlets), the owner
or operator shall report the results as required for each CMS. However,
when one CMS is used as a backup to another CMS, the owner or operator
shall report the results from the CMS used to meet the monitoring
requirements of this part. If both such CMS are used during a particular
reporting period to meet the monitoring requirements of this part, then
the owner or operator shall report the results from each CMS for the
relevant compliance period.
(c) Operation and maintenance of continuous monitoring systems. (1)
The owner or operator of an affected source shall maintain and operate
each CMS as specified in this section, or in a relevant standard, and in
a manner consistent with good air pollution control practices. (i) The
owner or operator of an affected source must maintain and operate each
CMS as specified in Sec. 63.6(e)(1).
(ii) The owner or operator must keep the necessary parts for routine
repairs of the affected CMS equipment readily available.
(iii) The owner or operator of an affected source must develop a
written startup, shutdown, and malfunction plan for CMS as specified in
Sec. 63.6(e)(3).
(2)(i) All CMS must be installed such that representative measures
of emissions or process parameters from the affected source are
obtained. In addition, CEMS must be located according to procedures
contained in the applicable performance specification(s).
(ii) Unless the individual subpart states otherwise, the owner or
operator must ensure the read out (that portion of the CMS that provides
a visual display or record), or other indication of operation, from any
CMS required for compliance with the emission standard is readily
accessible on site for operational control or inspection by the operator
of the equipment.
(3) All CMS shall be installed, operational, and the data verified
as specified in the relevant standard either prior to or in conjunction
with conducting performance tests under Sec. 63.7. Verification of
operational status shall, at a minimum, include completion of the
manufacturer's written specifications or recommendations for
installation, operation, and calibration of the system.
(4) Except for system breakdowns, out-of-control periods, repairs,
maintenance periods, calibration checks, and zero (low-level) and high-
level calibration drift adjustments, all CMS, including COMS and CEMS,
shall be in continuous operation and shall meet minimum frequency of
operation requirements as follows:
(i) All COMS shall complete a minimum of one cycle of sampling and
analyzing for each successive 10-second period and one cycle of data
recording for each successive 6-minute period.
(ii) All CEMS for measuring emissions other than opacity shall
complete a minimum of one cycle of operation (sampling, analyzing, and
data recording) for each successive 15-minute period.
(5) Unless otherwise approved by the Administrator, minimum
procedures for COMS shall include a method for producing a simulated
zero opacity condition and an upscale (high-level) opacity condition
using a certified neutral density filter or other related technique to
produce a known obscuration of the light beam. Such procedures shall
provide a system check of all the analyzer's internal optical surfaces
and all electronic circuitry, including the lamp and photodetector
assembly normally used in the measurement of opacity.
(6) The owner or operator of a CMS that is not a CPMS, which is
installed in accordance with the provisions of this part and the
applicable CMS performance specification(s), must check
[[Page 47]]
the zero (low-level) and high-level calibration drifts at least once
daily in accordance with the written procedure specified in the
performance evaluation plan developed under paragraphs (e)(3)(i) and
(ii) of this section. The zero (low-level) and high-level calibration
drifts must be adjusted, at a minimum, whenever the 24-hour zero (low-
level) drift exceeds two times the limits of the applicable performance
specification(s) specified in the relevant standard. The system shall
allow the amount of excess zero (low-level) and high-level drift
measured at the 24-hour interval checks to be recorded and quantified
whenever specified. For COMS, all optical and instrumental surfaces
exposed to the effluent gases must be cleaned prior to performing the
zero (low-level) and high-level drift adjustments; the optical surfaces
and instrumental surfaces must be cleaned when the cumulative automatic
zero compensation, if applicable, exceeds 4 percent opacity. The CPMS
must be calibrated prior to use for the purposes of complying with this
section. The CPMS must be checked daily for indication that the system
is responding. If the CPMS system includes an internal system check,
results must be recorded and checked daily for proper operation.
(7)(i) A CMS is out of control if--
(A) The zero (low-level), mid-level (if applicable), or high-level
calibration drift (CD) exceeds two times the applicable CD specification
in the applicable performance specification or in the relevant standard;
or
(B) The CMS fails a performance test audit (e.g., cylinder gas
audit), relative accuracy audit, relative accuracy test audit, or
linearity test audit; or
(C) The COMS CD exceeds two times the limit in the applicable
performance specification in the relevant standard.
(ii) When the CMS is out of control, the owner or operator of the
affected source shall take the necessary corrective action and shall
repeat all necessary tests which indicate that the system is out of
control. The owner or operator shall take corrective action and conduct
retesting until the performance requirements are below the applicable
limits. The beginning of the out-of-control period is the hour the owner
or operator conducts a performance check (e.g., calibration drift) that
indicates an exceedance of the performance requirements established
under this part. The end of the out-of-control period is the hour
following the completion of corrective action and successful
demonstration that the system is within the allowable limits. During the
period the CMS is out of control, recorded data shall not be used in
data averages and calculations, or to meet any data availability
requirement established under this part.
(8) The owner or operator of a CMS that is out of control as defined
in paragraph (c)(7) of this section shall submit all information
concerning out-of-control periods, including start and end dates and
hours and descriptions of corrective actions taken, in the excess
emissions and continuous monitoring system performance report required
in Sec. 63.10(e)(3).
(d) Quality control program. (1) The results of the quality control
program required in this paragraph will be considered by the
Administrator when he/she determines the validity of monitoring data.
(2) The owner or operator of an affected source that is required to
use a CMS and is subject to the monitoring requirements of this section
and a relevant standard shall develop and implement a CMS quality
control program. As part of the quality control program, the owner or
operator shall develop and submit to the Administrator for approval upon
request a site-specific performance evaluation test plan for the CMS
performance evaluation required in paragraph (e)(3)(i) of this section,
according to the procedures specified in paragraph (e). In addition,
each quality control program shall include, at a minimum, a written
protocol that describes procedures for each of the following operations:
(i) Initial and any subsequent calibration of the CMS;
(ii) Determination and adjustment of the calibration drift of the
CMS;
(iii) Preventive maintenance of the CMS, including spare parts
inventory;
(iv) Data recording, calculations, and reporting;
(v) Accuracy audit procedures, including sampling and analysis
methods; and
[[Page 48]]
(vi) Program of corrective action for a malfunctioning CMS.
(3) The owner or operator shall keep these written procedures on
record for the life of the affected source or until the affected source
is no longer subject to the provisions of this part, to be made
available for inspection, upon request, by the Administrator. If the
performance evaluation plan is revised, the owner or operator shall keep
previous (i.e., superseded) versions of the performance evaluation plan
on record to be made available for inspection, upon request, by the
Administrator, for a period of 5 years after each revision to the plan.
Where relevant, e.g., program of corrective action for a malfunctioning
CMS, these written procedures may be incorporated as part of the
affected source's startup, shutdown, and malfunction plan to avoid
duplication of planning and recordkeeping efforts.
(e) Performance evaluation of continuous monitoring systems--(1)
General. When required by a relevant standard, and at any other time the
Administrator may require under section 114 of the Act, the owner or
operator of an affected source being monitored shall conduct a
performance evaluation of the CMS. Such performance evaluation shall be
conducted according to the applicable specifications and procedures
described in this section or in the relevant standard.
(2) Notification of performance evaluation. The owner or operator
shall notify the Administrator in writing of the date of the performance
evaluation simultaneously with the notification of the performance test
date required under Sec. 63.7(b) or at least 60 days prior to the date
the performance evaluation is scheduled to begin if no performance test
is required.
(3)(i) Submission of site-specific performance evaluation test plan.
Before conducting a required CMS performance evaluation, the owner or
operator of an affected source shall develop and submit a site-specific
performance evaluation test plan to the Administrator for approval upon
request. The performance evaluation test plan shall include the
evaluation program objectives, an evaluation program summary, the
performance evaluation schedule, data quality objectives, and both an
internal and external QA program. Data quality objectives are the pre-
evaluation expectations of precision, accuracy, and completeness of
data.
(ii) The internal QA program shall include, at a minimum, the
activities planned by routine operators and analysts to provide an
assessment of CMS performance. The external QA program shall include, at
a minimum, systems audits that include the opportunity for on-site
evaluation by the Administrator of instrument calibration, data
validation, sample logging, and documentation of quality control data
and field maintenance activities.
(iii) The owner or operator of an affected source shall submit the
site-specific performance evaluation test plan to the Administrator (if
requested) at least 60 days before the performance test or performance
evaluation is scheduled to begin, or on a mutually agreed upon date, and
review and approval of the performance evaluation test plan by the
Administrator will occur with the review and approval of the site-
specific test plan (if review of the site-specific test plan is
requested).
(iv) The Administrator may request additional relevant information
after the submittal of a site-specific performance evaluation test plan.
(v) In the event that the Administrator fails to approve or
disapprove the site-specific performance evaluation test plan within the
time period specified in Sec. 63.7(c)(3), the following conditions
shall apply:
(A) If the owner or operator intends to demonstrate compliance using
the monitoring method(s) specified in the relevant standard, the owner
or operator shall conduct the performance evaluation within the time
specified in this subpart using the specified method(s);
(B) If the owner or operator intends to demonstrate compliance by
using an alternative to a monitoring method specified in the relevant
standard, the owner or operator shall refrain from conducting the
performance evaluation until the Administrator approves the use of the
alternative method. If the Administrator does not approve the use of the
alternative method within 30 days before the performance evaluation
[[Page 49]]
is scheduled to begin, the performance evaluation deadlines specified in
paragraph (e)(4) of this section may be extended such that the owner or
operator shall conduct the performance evaluation within 60 calendar
days after the Administrator approves the use of the alternative method.
Notwithstanding the requirements in the preceding two sentences, the
owner or operator may proceed to conduct the performance evaluation as
required in this section (without the Administrator's prior approval of
the site-specific performance evaluation test plan) if he/she
subsequently chooses to use the specified monitoring method(s) instead
of an alternative.
(vi) Neither the submission of a site-specific performance
evaluation test plan for approval, nor the Administrator's approval or
disapproval of a plan, nor the Administrator's failure to approve or
disapprove a plan in a timely manner shall--
(A) Relieve an owner or operator of legal responsibility for
compliance with any applicable provisions of this part or with any other
applicable Federal, State, or local requirement; or
(B) Prevent the Administrator from implementing or enforcing this
part or taking any other action under the Act.
(4) Conduct of performance evaluation and performance evaluation
dates. The owner or operator of an affected source shall conduct a
performance evaluation of a required CMS during any performance test
required under Sec. 63.7 in accordance with the applicable performance
specification as specified in the relevant standard. Notwithstanding the
requirement in the previous sentence, if the owner or operator of an
affected source elects to submit COMS data for compliance with a
relevant opacity emission standard as provided under Sec. 63.6(h)(7),
he/she shall conduct a performance evaluation of the COMS as specified
in the relevant standard, before the performance test required under
Sec. 63.7 is conducted in time to submit the results of the performance
evaluation as specified in paragraph (e)(5)(ii) of this section. If a
performance test is not required, or the requirement for a performance
test has been waived under Sec. 63.7(h), the owner or operator of an
affected source shall conduct the performance evaluation not later than
180 days after the appropriate compliance date for the affected source,
as specified in Sec. 63.7(a), or as otherwise specified in the relevant
standard.
(5) Reporting performance evaluation results. (i) The owner or
operator shall furnish the Administrator a copy of a written report of
the results of the performance evaluation containing the information
specified in Sec. 63.7(g)(2)(i) through (vi) simultaneously with the
results of the performance test required under Sec. 63.7 or within 60
days of completion of the performance evaluation, unless otherwise
specified in a relevant standard.
(ii) The owner or operator of an affected source using a COMS to
determine opacity compliance during any performance test required under
Sec. 63.7 and described in Sec. 63.6(d)(6) shall furnish the
Administrator two or, upon request, three copies of a written report of
the results of the COMS performance evaluation under this paragraph. The
copies shall be provided at least 15 calendar days before the
performance test required under Sec. 63.7 is conducted.
(f) Use of an alternative monitoring method--(1) General. Until
permission to use an alternative monitoring procedure (minor,
intermediate, or major changes; see definition in Sec. 63.90(a)) has
been granted by the Administrator under this paragraph (f)(1), the owner
or operator of an affected source remains subject to the requirements of
this section and the relevant standard.
(2) After receipt and consideration of written application, the
Administrator may approve alternatives to any monitoring methods or
procedures of this part including, but not limited to, the following:
(i) Alternative monitoring requirements when installation of a CMS
specified by a relevant standard would not provide accurate measurements
due to liquid water or other interferences caused by substances within
the effluent gases;
(ii) Alternative monitoring requirements when the affected source is
infrequently operated;
[[Page 50]]
(iii) Alternative monitoring requirements to accommodate CEMS that
require additional measurements to correct for stack moisture
conditions;
(iv) Alternative locations for installing CMS when the owner or
operator can demonstrate that installation at alternate locations will
enable accurate and representative measurements;
(v) Alternate methods for converting pollutant concentration
measurements to units of the relevant standard;
(vi) Alternate procedures for performing daily checks of zero (low-
level) and high-level drift that do not involve use of high-level gases
or test cells;
(vii) Alternatives to the American Society for Testing and Materials
(ASTM) test methods or sampling procedures specified by any relevant
standard;
(viii) Alternative CMS that do not meet the design or performance
requirements in this part, but adequately demonstrate a definite and
consistent relationship between their measurements and the measurements
of opacity by a system complying with the requirements as specified in
the relevant standard. The Administrator may require that such
demonstration be performed for each affected source; or
(ix) Alternative monitoring requirements when the effluent from a
single affected source or the combined effluent from two or more
affected sources is released to the atmosphere through more than one
point.
(3) If the Administrator finds reasonable grounds to dispute the
results obtained by an alternative monitoring method, requirement, or
procedure, the Administrator may require the use of a method,
requirement, or procedure specified in this section or in the relevant
standard. If the results of the specified and alternative method,
requirement, or procedure do not agree, the results obtained by the
specified method, requirement, or procedure shall prevail.
(4)(i) Request to use alternative monitoring procedure. An owner or
operator who wishes to use an alternative monitoring procedure must
submit an application to the Administrator as described in paragraph
(f)(4)(ii) of this section. The application may be submitted at any time
provided that the monitoring procedure is not the performance test
method used to demonstrate compliance with a relevant standard or other
requirement. If the alternative monitoring procedure will serve as the
performance test method that is to be used to demonstrate compliance
with a relevant standard, the application must be submitted at least 60
days before the performance evaluation is scheduled to begin and must
meet the requirements for an alternative test method under Sec.
63.7(f).
(ii) The application must contain a description of the proposed
alternative monitoring system which addresses the four elements
contained in the definition of monitoring in Sec. 63.2 and a
performance evaluation test plan, if required, as specified in paragraph
(e)(3) of this section. In addition, the application must include
information justifying the owner or operator's request for an
alternative monitoring method, such as the technical or economic
infeasibility, or the impracticality, of the affected source using the
required method.
(iii) The owner or operator may submit the information required in
this paragraph well in advance of the submittal dates specified in
paragraph (f)(4)(i) above to ensure a timely review by the Administrator
in order to meet the compliance demonstration date specified in this
section or the relevant standard.
(iv) Application for minor changes to monitoring procedures, as
specified in paragraph (b)(1) of this section, may be made in the site-
specific performance evaluation plan.
(5) Approval of request to use alternative monitoring procedure. (i)
The Administrator will notify the owner or operator of approval or
intention to deny approval of the request to use an alternative
monitoring method within 30 calendar days after receipt of the original
request and within 30 calendar days after receipt of any supplementary
information that is submitted. If a request for a minor change is made
in conjunction with site-specific performance evaluation plan, then
[[Page 51]]
approval of the plan will constitute approval of the minor change.
Before disapproving any request to use an alternative monitoring method,
the Administrator will notify the applicant of the Administrator's
intention to disapprove the request together with--
(A) Notice of the information and findings on which the intended
disapproval is based; and
(B) Notice of opportunity for the owner or operator to present
additional information to the Administrator before final action on the
request. At the time the Administrator notifies the applicant of his or
her intention to disapprove the request, the Administrator will specify
how much time the owner or operator will have after being notified of
the intended disapproval to submit the additional information.
(ii) The Administrator may establish general procedures and criteria
in a relevant standard to accomplish the requirements of paragraph
(f)(5)(i) of this section.
(iii) If the Administrator approves the use of an alternative
monitoring method for an affected source under paragraph (f)(5)(i) of
this section, the owner or operator of such source shall continue to use
the alternative monitoring method until he or she receives approval from
the Administrator to use another monitoring method as allowed by Sec.
63.8(f).
(6) Alternative to the relative accuracy test. An alternative to the
relative accuracy test for CEMS specified in a relevant standard may be
requested as follows:
(i) Criteria for approval of alternative procedures. An alternative
to the test method for determining relative accuracy is available for
affected sources with emission rates demonstrated to be less than 50
percent of the relevant standard. The owner or operator of an affected
source may petition the Administrator under paragraph (f)(6)(ii) of this
section to substitute the relative accuracy test in section 7 of
Performance Specification 2 with the procedures in section 10 if the
results of a performance test conducted according to the requirements in
Sec. 63.7, or other tests performed following the criteria in Sec.
63.7, demonstrate that the emission rate of the pollutant of interest in
the units of the relevant standard is less than 50 percent of the
relevant standard. For affected sources subject to emission limitations
expressed as control efficiency levels, the owner or operator may
petition the Administrator to substitute the relative accuracy test with
the procedures in section 10 of Performance Specification 2 if the
control device exhaust emission rate is less than 50 percent of the
level needed to meet the control efficiency requirement. The alternative
procedures do not apply if the CEMS is used continuously to determine
compliance with the relevant standard.
(ii) Petition to use alternative to relative accuracy test. The
petition to use an alternative to the relative accuracy test shall
include a detailed description of the procedures to be applied, the
location and the procedure for conducting the alternative, the
concentration or response levels of the alternative relative accuracy
materials, and the other equipment checks included in the alternative
procedure(s). The Administrator will review the petition for
completeness and applicability. The Administrator's determination to
approve an alternative will depend on the intended use of the CEMS data
and may require specifications more stringent than in Performance
Specification 2.
(iii) Rescission of approval to use alternative to relative accuracy
test. The Administrator will review the permission to use an alternative
to the CEMS relative accuracy test and may rescind such permission if
the CEMS data from a successful completion of the alternative relative
accuracy procedure indicate that the affected source's emissions are
approaching the level of the relevant standard. The criterion for
reviewing the permission is that the collection of CEMS data shows that
emissions have exceeded 70 percent of the relevant standard for any
averaging period, as specified in the relevant standard. For affected
sources subject to emission limitations expressed as control efficiency
levels, the criterion for reviewing the permission is that the
collection of CEMS data shows that exhaust emissions have exceeded 70
percent of the level needed to meet the control efficiency requirement
for any
[[Page 52]]
averaging period, as specified in the relevant standard. The owner or
operator of the affected source shall maintain records and determine the
level of emissions relative to the criterion for permission to use an
alternative for relative accuracy testing. If this criterion is
exceeded, the owner or operator shall notify the Administrator within 10
days of such occurrence and include a description of the nature and
cause of the increased emissions. The Administrator will review the
notification and may rescind permission to use an alternative and
require the owner or operator to conduct a relative accuracy test of the
CEMS as specified in section 7 of Performance Specification 2. The
Administrator will review the notification and may rescind permission to
use an alternative and require the owner or operator to conduct a
relative accuracy test of the CEMS as specified in section 8.4 of
Performance Specification 2.
(g) Reduction of monitoring data. (1) The owner or operator of each
CMS must reduce the monitoring data as specified in paragraphs (g)(1)
through (5) of this section.
(2) The owner or operator of each COMS shall reduce all data to 6-
minute averages calculated from 36 or more data points equally spaced
over each 6-minute period. Data from CEMS for measurement other than
opacity, unless otherwise specified in the relevant standard, shall be
reduced to 1-hour averages computed from four or more data points
equally spaced over each 1-hour period, except during periods when
calibration, quality assurance, or maintenance activities pursuant to
provisions of this part are being performed. During these periods, a
valid hourly average shall consist of at least two data points with each
representing a 15-minute period. Alternatively, an arithmetic or
integrated 1-hour average of CEMS data may be used. Time periods for
averaging are defined in Sec. 63.2.
(3) The data may be recorded in reduced or nonreduced form (e.g.,
ppm pollutant and percent O2 or ng/J of pollutant).
(4) All emission data shall be converted into units of the relevant
standard for reporting purposes using the conversion procedures
specified in that standard. After conversion into units of the relevant
standard, the data may be rounded to the same number of significant
digits as used in that standard to specify the emission limit (e.g.,
rounded to the nearest 1 percent opacity).
(5) Monitoring data recorded during periods of unavoidable CMS
breakdowns, out-of-control periods, repairs, maintenance periods,
calibration checks, and zero (low-level) and high-level adjustments must
not be included in any data average computed under this part. For the
owner or operator complying with the requirements of Sec.
63.10(b)(2)(vii)(A) or (B), data averages must include any data recorded
during periods of monitor breakdown or malfunction.

delivered or postmarked within 15 calendar days after that date.
(iii) Unless the owner or operator has requested and received prior
permission from the Administrator to submit less than the information in
Sec. 63.5(d),
[[Page 54]]
the notification must include the information required on the
application for approval of construction or reconstruction as specified
in Sec. 63.5(d)(1)(i).
(c) Request for extension of compliance. If the owner or operator of
an affected source cannot comply with a relevant standard by the
applicable compliance date for that source, or if the owner or operator
has installed BACT or technology to meet LAER consistent with Sec.
63.6(i)(5) of this subpart, he/she may submit to the Administrator (or
the State with an approved permit program) a request for an extension of
compliance as specified in Sec. 63.6(i)(4) through Sec. 63.6(i)(6).
(d) Notification that source is subject to special compliance
requirements. An owner or operator of a new source that is subject to
special compliance requirements as specified in Sec. 63.6(b)(3) and
Sec. 63.6(b)(4) shall notify the Administrator of his/her compliance
obligations not later than the notification dates established in
paragraph (b) of this section for new sources that are not subject to
the special provisions.
(e) Notification of performance test. The owner or operator of an
affected source shall notify the Administrator in writing of his or her
intention to conduct a performance test at least 60 calendar days before
the performance test is scheduled to begin to allow the Administrator to
review and approve the site-specific test plan required under Sec.
63.7(c), if requested by the Administrator, and to have an observer
present during the test.
(f) Notification of opacity and visible emission observations. The
owner or operator of an affected source shall notify the Administrator
in writing of the anticipated date for conducting the opacity or visible
emission observations specified in Sec. 63.6(h)(5), if such
observations are required for the source by a relevant standard. The
notification shall be submitted with the notification of the performance
test date, as specified in paragraph (e) of this section, or if no
performance test is required or visibility or other conditions prevent
the opacity or visible emission observations from being conducted
concurrently with the initial performance test required under Sec.
63.7, the owner or operator shall deliver or postmark the notification
not less than 30 days before the opacity or visible emission
observations are scheduled to take place.
(g) Additional notification requirements for sources with continuous
monitoring systems. The owner or operator of an affected source required
to use a CMS by a relevant standard shall furnish the Administrator
written notification as follows:
(1) A notification of the date the CMS performance evaluation under
Sec. 63.8(e) is scheduled to begin, submitted simultaneously with the
notification of the performance test date required under Sec. 63.7(b).
If no performance test is required, or if the requirement to conduct a
performance test has been waived for an affected source under Sec.
63.7(h), the owner or operator shall notify the Administrator in writing
of the date of the performance evaluation at least 60 calendar days
before the evaluation is scheduled to begin;
(2) A notification that COMS data results will be used to determine
compliance with the applicable opacity emission standard during a
performance test required by Sec. 63.7 in lieu of Method 9 or other
opacity emissions test method data, as allowed by Sec. 63.6(h)(7)(ii),
if compliance with an opacity emission standard is required for the
source by a relevant standard. The notification shall be submitted at
least 60 calendar days before the performance test is scheduled to
begin; and
(3) A notification that the criterion necessary to continue use of
an alternative to relative accuracy testing, as provided by Sec.
63.8(f)(6), has been exceeded. The notification shall be delivered or
postmarked not later than 10 days after the occurrence of such
exceedance, and it shall include a description of the nature and cause
of the increased emissions.
(h) Notification of compliance status. (1) The requirements of
paragraphs (h)(2) through (h)(4) of this section apply when an affected
source becomes subject to a relevant standard.
(2)(i) Before a title V permit has been issued to the owner or
operator of an affected source, and each time a notification of
compliance status is required under this part, the owner or operator
[[Page 55]]
of such source shall submit to the Administrator a notification of
compliance status, signed by the responsible official who shall certify
its accuracy, attesting to whether the source has complied with the
relevant standard. The notification shall list--
(A) The methods that were used to determine compliance;
(B) The results of any performance tests, opacity or visible
emission observations, continuous monitoring system (CMS) performance
evaluations, and/or other monitoring procedures or methods that were
conducted;
(C) The methods that will be used for determining continuing
compliance, including a description of monitoring and reporting
requirements and test methods;
(D) The type and quantity of hazardous air pollutants emitted by the
source (or surrogate pollutants if specified in the relevant standard),
reported in units and averaging times and in accordance with the test
methods specified in the relevant standard;
(E) If the relevant standard applies to both major and area sources,
an analysis demonstrating whether the affected source is a major source
(using the emissions data generated for this notification);
(F) A description of the air pollution control equipment (or method)
for each emission point, including each control device (or method) for
each hazardous air pollutant and the control efficiency (percent) for
each control device (or method); and
(G) A statement by the owner or operator of the affected existing,
new, or reconstructed source as to whether the source has complied with
the relevant standard or other requirements.
(ii) The notification must be sent before the close of business on
the 60th day following the completion of the relevant compliance
demonstration activity specified in the relevant standard (unless a
different reporting period is specified in the standard, in which case
the letter must be sent before the close of business on the day the
report of the relevant testing or monitoring results is required to be
delivered or postmarked). For example, the notification shall be sent
before close of business on the 60th (or other required) day following
completion of the initial performance test and again before the close of
business on the 60th (or other required) day following the completion of
any subsequent required performance test. If no performance test is
required but opacity or visible emission observations are required to
demonstrate compliance with an opacity or visible emission standard
under this part, the notification of compliance status shall be sent
before close of business on the 30th day following the completion of
opacity or visible emission observations. Notifications may be combined
as long as the due date requirement for each notification is met.
(3) After a title V permit has been issued to the owner or operator
of an affected source, the owner or operator of such source shall comply
with all requirements for compliance status reports contained in the
source's title V permit, including reports required under this part.
After a title V permit has been issued to the owner or operator of an
affected source, and each time a notification of compliance status is
required under this part, the owner or operator of such source shall
submit the notification of compliance status to the appropriate
permitting authority following completion of the relevant compliance
demonstration activity specified in the relevant standard.
(4) [Reserved]
(5) If an owner or operator of an affected source submits estimates
or preliminary information in the application for approval of
construction or reconstruction required in Sec. 63.5(d) in place of the
actual emissions data or control efficiencies required in paragraphs
(d)(1)(ii)(H) and (d)(2) of Sec. 63.5, the owner or operator shall
submit the actual emissions data and other correct information as soon
as available but no later than with the initial notification of
compliance status required in this section.
(6) Advice on a notification of compliance status may be obtained
from the Administrator.
(i) Adjustment to time periods or postmark deadlines for submittal
and review of required communications. (1)(i) Until an adjustment of a
time period or postmark deadline has been approved by
[[Page 56]]
the Administrator under paragraphs (i)(2) and (i)(3) of this section,
the owner or operator of an affected source remains strictly subject to
the requirements of this part.
(ii) An owner or operator shall request the adjustment provided for
in paragraphs (i)(2) and (i)(3) of this section each time he or she
wishes to change an applicable time period or postmark deadline
specified in this part.
(2) Notwithstanding time periods or postmark deadlines specified in
this part for the submittal of information to the Administrator by an
owner or operator, or the review of such information by the
Administrator, such time periods or deadlines may be changed by mutual
agreement between the owner or operator and the Administrator. An owner
or operator who wishes to request a change in a time period or postmark
deadline for a particular requirement shall request the adjustment in
writing as soon as practicable before the subject activity is required
to take place. The owner or operator shall include in the request
whatever information he or she considers useful to convince the
Administrator that an adjustment is warranted.
(3) If, in the Administrator's judgment, an owner or operator's
request for an adjustment to a particular time period or postmark
deadline is warranted, the Administrator will approve the adjustment.
The Administrator will notify the owner or operator in writing of
approval or disapproval of the request for an adjustment within 15
calendar days of receiving sufficient information to evaluate the
request.
(4) If the Administrator is unable to meet a specified deadline, he
or she will notify the owner or operator of any significant delay and
inform the owner or operator of the amended schedule.
(j) Change in information already provided. Any change in the
information already provided under this section shall be provided to the
Administrator in writing within 15 calendar days after the change.

Sec. 63.10 Recordkeeping and reporting requirements.
(a) Applicability and general information. (1) The applicability of
this section is set out in Sec. 63.1(a)(4).
(2) For affected sources that have been granted an extension of
compliance under subpart D of this part, the requirements of this
section do not apply to those sources while they are operating under
such compliance extensions.
(3) If any State requires a report that contains all the information
required in a report listed in this section, an owner or operator may
send the Administrator a copy of the report sent to the State to satisfy
the requirements of this section for that report.
(4)(i) Before a State has been delegated the authority to implement
and enforce recordkeeping and reporting requirements established under
this part, the owner or operator of an affected source in such State
subject to such requirements shall submit reports to the appropriate
Regional Office of the EPA (to the attention of the Director of the
Division indicated in the list of the EPA Regional Offices in Sec.
63.13).
(ii) After a State has been delegated the authority to implement and
enforce recordkeeping and reporting requirements established under this
part, the owner or operator of an affected source in such State subject
to such requirements shall submit reports to the delegated State
authority (which may be the same as the permitting authority). In
addition, if the delegated (permitting) authority is the State, the
owner or operator shall send a copy of each report submitted to the
State to the appropriate Regional Office of the EPA, as specified in
paragraph (a)(4)(i) of this section. The Regional Office may waive this
requirement for any reports at its discretion.
(5) If an owner or operator of an affected source in a State with
delegated authority is required to submit periodic reports under this
part to the State, and if the State has an established timeline for the
submission of periodic reports that is consistent with the reporting
frequency(ies) specified for such source under this part, the owner or
operator may change the dates by which periodic reports under
[[Page 57]]
this part shall be submitted (without changing the frequency of
reporting) to be consistent with the State's schedule by mutual
agreement between the owner or operator and the State. For each relevant
standard established pursuant to section 112 of the Act, the allowance
in the previous sentence applies in each State beginning 1 year after
the affected source's compliance date for that standard. Procedures
governing the implementation of this provision are specified in Sec.
63.9(i).
(6) If an owner or operator supervises one or more stationary
sources affected by more than one standard established pursuant to
section 112 of the Act, he/she may arrange by mutual agreement between
the owner or operator and the Administrator (or the State permitting
authority) a common schedule on which periodic reports required for each
source shall be submitted throughout the year. The allowance in the
previous sentence applies in each State beginning 1 year after the
latest compliance date for any relevant standard established pursuant to
section 112 of the Act for any such affected source(s). Procedures
governing the implementation of this provision are specified in Sec.
63.9(i).
(7) If an owner or operator supervises one or more stationary
sources affected by standards established pursuant to section 112 of the
Act (as amended November 15, 1990) and standards set under part 60, part
61, or both such parts of this chapter, he/she may arrange by mutual
agreement between the owner or operator and the Administrator (or the
State permitting authority) a common schedule on which periodic reports
required by each relevant (i.e., applicable) standard shall be submitted
throughout the year. The allowance in the previous sentence applies in
each State beginning 1 year after the stationary source is required to
be in compliance with the relevant section 112 standard, or 1 year after
the stationary source is required to be in compliance with the
applicable part 60 or part 61 standard, whichever is latest. Procedures
governing the implementation of this provision are specified in Sec.
63.9(i).
(b) General recordkeeping requirements. (1) The owner or operator of
an affected source subject to the provisions of this part shall maintain
files of all information (including all reports and notifications)
required by this part recorded in a form suitable and readily available
for expeditious inspection and review. The files shall be retained for
at least 5 years following the date of each occurrence, measurement,
maintenance, corrective action, report, or record. At a minimum, the
most recent 2 years of data shall be retained on site. The remaining 3
years of data may be retained off site. Such files may be maintained on
microfilm, on a computer, on computer floppy disks, on magnetic tape
disks, or on microfiche.
(2) The owner or operator of an affected source subject to the
provisions of this part shall maintain relevant records for such source
of--
(i) The occurrence and duration of each startup or shutdown when the
startup or shutdown causes the source to exceed any applicable emission
limitation in the relevant emission standards;
(ii) The occurrence and duration of each malfunction of operation
(i.e., process equipment) or the required air pollution control and
monitoring equipment;
(iii) All required maintenance performed on the air pollution
control and monitoring equipment;
(iv)(A) Actions taken during periods of startup or shutdown when the
source exceeded applicable emission limitations in a relevant standard
and when the actions taken are different from the procedures specified
in the affected source's startup, shutdown, and malfunction plan (see
Sec. 63.6(e)(3)); or
(B) Actions taken during periods of malfunction (including
corrective actions to restore malfunctioning process and air pollution
control and monitoring equipment to its normal or usual manner of
operation) when the actions taken are different from the procedures
specified in the affected source's startup, shutdown, and malfunction
plan (see Sec. 63.6(e)(3));
(v) All information necessary, including actions taken, to
demonstrate conformance with the affected source's startup, shutdown,
and malfunction plan (see Sec. 63.6(e)(3)) when all actions taken
during periods of startup or
[[Page 58]]
shutdown (and the startup or shutdown causes the source to exceed any
applicable emission limitation in the relevant emission standards), and
malfunction (including corrective actions to restore malfunctioning
process and air pollution control and monitoring equipment to its normal
or usual manner of operation) are consistent with the procedures
specified in such plan. (The information needed to demonstrate
conformance with the startup, shutdown, and malfunction plan may be
recorded using a ``checklist,'' or some other effective form of
recordkeeping, in order to minimize the recordkeeping burden for
conforming events);
(vi) Each period during which a CMS is malfunctioning or inoperative
(including out-of-control periods);
(vii) All required measurements needed to demonstrate compliance
with a relevant standard (including, but not limited to, 15-minute
averages of CMS data, raw performance testing measurements, and raw
performance evaluation measurements, that support data that the source
is required to report);
(A) This paragraph applies to owners or operators required to
install a continuous emissions monitoring system (CEMS) where the CEMS
installed is automated, and where the calculated data averages do not
exclude periods of CEMS breakdown or malfunction. An automated CEMS
records and reduces the measured data to the form of the pollutant
emission standard through the use of a computerized data acquisition
system. In lieu of maintaining a file of all CEMS subhourly measurements
as required under paragraph (b)(2)(vii) of this section, the owner or
operator shall retain the most recent consecutive three averaging
periods of subhourly measurements and a file that contains a hard copy
of the data acquisition system algorithm used to reduce the measured
data into the reportable form of the standard.
(B) This paragraph applies to owners or operators required to
install a CEMS where the measured data is manually reduced to obtain the
reportable form of the standard, and where the calculated data averages
do not exclude periods of CEMS breakdown or malfunction. In lieu of
maintaining a file of all CEMS subhourly measurements as required under
paragraph (b)(2)(vii) of this section, the owner or operator shall
retain all subhourly measurements for the most recent reporting period.
The subhourly measurements shall be retained for 120 days from the date
of the most recent summary or excess emission report submitted to the
Administrator.
(C) The Administrator or delegated authority, upon notification to
the source, may require the owner or operator to maintain all
measurements as required by paragraph (b)(2)(vii), if the administrator
or the delegated authority determines these records are required to more
accurately assess the compliance status of the affected source.
(viii) All results of performance tests, CMS performance
evaluations, and opacity and visible emission observations;
(ix) All measurements as may be necessary to determine the
conditions of performance tests and performance evaluations;
(x) All CMS calibration checks;
(xi) All adjustments and maintenance performed on CMS;
(xii) Any information demonstrating whether a source is meeting the
requirements for a waiver of recordkeeping or reporting requirements
under this part, if the source has been granted a waiver under paragraph
(f) of this section;
(xiii) All emission levels relative to the criterion for obtaining
permission to use an alternative to the relative accuracy test, if the
source has been granted such permission under Sec. 63.8(f)(6); and
(xiv) All documentation supporting initial notifications and
notifications of compliance status under Sec. 63.9.
(3) Recordkeeping requirement for applicability determinations. If
an owner or operator determines that his or her stationary source that
emits (or has the potential to emit, without considering controls) one
or more hazardous air pollutants regulated by any standard established
pursuant to section 112(d) or (f), and that stationary source is in the
source category regulated by the relevant standard, but that source
[[Page 59]]
is not subject to the relevant standard (or other requirement
established under this part) because of limitations on the source's
potential to emit or an exclusion, the owner or operator must keep a
record of the applicability determination on site at the source for a
period of 5 years after the determination, or until the source changes
its operations to become an affected source, whichever comes first. The
record of the applicability determination must be signed by the person
making the determination and include an analysis (or other information)
that demonstrates why the owner or operator believes the source is
unaffected (e.g., because the source is an area source). The analysis
(or other information) must be sufficiently detailed to allow the
Administrator to make a finding about the source's applicability status
with regard to the relevant standard or other requirement. If relevant,
the analysis must be performed in accordance with requirements
established in relevant subparts of this part for this purpose for
particular categories of stationary sources. If relevant, the analysis
should be performed in accordance with EPA guidance materials published
to assist sources in making applicability determinations under section
112, if any. The requirements to determine applicability of a standard
under Sec. 63.1(b)(3) and to record the results of that determination
under paragraph (b)(3) of this section shall not by themselves create an
obligation for the owner or operator to obtain a title V permit.
(c) Additional recordkeeping requirements for sources with
continuous monitoring systems. In addition to complying with the
requirements specified in paragraphs (b)(1) and (b)(2) of this section,
the owner or operator of an affected source required to install a CMS by
a relevant standard shall maintain records for such source of--
(1) All required CMS measurements (including monitoring data
recorded during unavoidable CMS breakdowns and out-of-control periods);
(2)-(4) [Reserved]
(5) The date and time identifying each period during which the CMS
was inoperative except for zero (low-level) and high-level checks;
(6) The date and time identifying each period during which the CMS
was out of control, as defined in Sec. 63.8(c)(7);
(7) The specific identification (i.e., the date and time of
commencement and completion) of each period of excess emissions and
parameter monitoring exceedances, as defined in the relevant
standard(s), that occurs during startups, shutdowns, and malfunctions of
the affected source;
(8) The specific identification (i.e., the date and time of
commencement and completion) of each time period of excess emissions and
parameter monitoring exceedances, as defined in the relevant
standard(s), that occurs during periods other than startups, shutdowns,
and malfunctions of the affected source;
(9) [Reserved]
(10) The nature and cause of any malfunction (if known);
(11) The corrective action taken or preventive measures adopted;
(12) The nature of the repairs or adjustments to the CMS that was
inoperative or out of control;
(13) The total process operating time during the reporting period;
and
(14) All procedures that are part of a quality control program
developed and implemented for CMS under Sec. 63.8(d).
(15) In order to satisfy the requirements of paragraphs (c)(10)
through (c)(12) of this section and to avoid duplicative recordkeeping
efforts, the owner or operator may use the affected source's startup,
shutdown, and malfunction plan or records kept to satisfy the
recordkeeping requirements of the startup, shutdown, and malfunction
plan specified in Sec. 63.6(e), provided that such plan and records
adequately address the requirements of paragraphs (c)(10) through
(c)(12).
(d) General reporting requirements. (1) Notwithstanding the
requirements in this paragraph or paragraph (e) of this section, and
except as provided in Sec. 63.16, the owner or operator of an affected
source subject to reporting requirements under this part shall submit
reports to the Administrator in accordance with the reporting
requirements in the relevant standard(s).
(2) Reporting results of performance tests. Before a title V permit
has been issued to the owner or operator of an
[[Page 60]]
affected source, the owner or operator shall report the results of any
performance test under Sec. 63.7 to the Administrator. After a title V
permit has been issued to the owner or operator of an affected source,
the owner or operator shall report the results of a required performance
test to the appropriate permitting authority. The owner or operator of
an affected source shall report the results of the performance test to
the Administrator (or the State with an approved permit program) before
the close of business on the 60th day following the completion of the
performance test, unless specified otherwise in a relevant standard or
as approved otherwise in writing by the Administrator. The results of
the performance test shall be submitted as part of the notification of
compliance status required under Sec. 63.9(h).
(3) Reporting results of opacity or visible emission observations.
The owner or operator of an affected source required to conduct opacity
or visible emission observations by a relevant standard shall report the
opacity or visible emission results (produced using Test Method 9 or
Test Method 22, or an alternative to these test methods) along with the
results of the performance test required under Sec. 63.7. If no
performance test is required, or if visibility or other conditions
prevent the opacity or visible emission observations from being
conducted concurrently with the performance test required under Sec.
63.7, the owner or operator shall report the opacity or visible emission
results before the close of business on the 30th day following the
completion of the opacity or visible emission observations.
(4) Progress reports. The owner or operator of an affected source
who is required to submit progress reports as a condition of receiving
an extension of compliance under Sec. 63.6(i) shall submit such reports
to the Administrator (or the State with an approved permit program) by
the dates specified in the written extension of compliance.
(5)(i) Periodic startup, shutdown, and malfunction reports. If
actions taken by an owner or operator during a startup or shutdown (and
the startup or shutdown causes the source to exceed any applicable
emission limitation in the relevant emission standards), or malfunction
of an affected source (including actions taken to correct a malfunction)
are consistent with the procedures specified in the source's startup,
shutdown, and malfunction plan (see Sec. 63.6(e)(3)), the owner or
operator shall state such information in a startup, shutdown, and
malfunction report. Actions taken to minimize emissions during such
startups, shutdowns, and malfunctions shall be summarized in the report
and may be done in checklist form; if actions taken are the same for
each event, only one checklist is necessary. Such a report shall also
include the number, duration, and a brief description for each type of
malfunction which occurred during the reporting period and which caused
or may have caused any applicable emission limitation to be exceeded.
Reports shall only be required if a startup or shutdown caused the
source to exceed any applicable emission limitation in the relevant
emission standards, or if a malfunction occurred during the reporting
period. The startup, shutdown, and malfunction report shall consist of a
letter, containing the name, title, and signature of the owner or
operator or other responsible official who is certifying its accuracy,
that shall be submitted to the Administrator semiannually (or on a more
frequent basis if specified otherwise in a relevant standard or as
established otherwise by the permitting authority in the source's title
V permit). The startup, shutdown, and malfunction report shall be
delivered or postmarked by the 30th day following the end of each
calendar half (or other calendar reporting period, as appropriate). If
the owner or operator is required to submit excess emissions and
continuous monitoring system performance (or other periodic) reports
under this part, the startup, shutdown, and malfunction reports required
under this paragraph may be submitted simultaneously with the excess
emissions and continuous monitoring system performance (or other)
reports. If startup, shutdown, and malfunction reports are submitted
with excess emissions and continuous monitoring system performance (or
other periodic) reports, and the owner or operator receives approval to
reduce the frequency
[[Page 61]]
of reporting for the latter under paragraph (e) of this section, the
frequency of reporting for the startup, shutdown, and malfunction
reports also may be reduced if the Administrator does not object to the
intended change. The procedures to implement the allowance in the
preceding sentence shall be the same as the procedures specified in
paragraph (e)(3) of this section.
(ii) Immediate startup, shutdown, and malfunction reports.
Notwithstanding the allowance to reduce the frequency of reporting for
periodic startup, shutdown, and malfunction reports under paragraph
(d)(5)(i) of this section, any time an action taken by an owner or
operator during a startup or shutdown that caused the source to exceed
any applicable emission limitation in the relevant emission standards,
or malfunction (including actions taken to correct a malfunction) is not
consistent with the procedures specified in the affected source's
startup, shutdown, and malfunction plan, the owner or operator shall
report the actions taken for that event within 2 working days after
commencing actions inconsistent with the plan followed by a letter
within 7 working days after the end of the event. The immediate report
required under this paragraph (d)(5)(ii) shall consist of a telephone
call (or facsimile (FAX) transmission) to the Administrator within 2
working days after commencing actions inconsistent with the plan, and it
shall be followed by a letter, delivered or postmarked within 7 working
days after the end of the event, that contains the name, title, and
signature of the owner or operator or other responsible official who is
certifying its accuracy, explaining the circumstances of the event, the
reasons for not following the startup, shutdown, and malfunction plan,
describing all excess emissions and/or parameter monitoring exceedances
which are believed to have occurred (or could have occurred in the case
of malfunctions), and actions taken to minimize emissions in conformance
with Sec. 63.6(e)(1)(i). Notwithstanding the requirements of the
previous sentence, after the effective date of an approved permit
program in the State in which an affected source is located, the owner
or operator may make alternative reporting arrangements, in advance,
with the permitting authority in that State. Procedures governing the
arrangement of alternative reporting requirements under this paragraph
(d)(5)(ii) are specified in Sec. 63.9(i).
(e) Additional reporting requirements for sources with continuous
monitoring systems--(1) General. When more than one CEMS is used to
measure the emissions from one affected source (e.g., multiple
breechings, multiple outlets), the owner or operator shall report the
results as required for each CEMS.
(2) Reporting results of continuous monitoring system performance
evaluations. (i) The owner or operator of an affected source required to
install a CMS by a relevant standard shall furnish the Administrator a
copy of a written report of the results of the CMS performance
evaluation, as required under Sec. 63.8(e), simultaneously with the
results of the performance test required under Sec. 63.7, unless
otherwise specified in the relevant standard.
(ii) The owner or operator of an affected source using a COMS to
determine opacity compliance during any performance test required under
Sec. 63.7 and described in Sec. 63.6(d)(6) shall furnish the
Administrator two or, upon request, three copies of a written report of
the results of the COMS performance evaluation conducted under Sec.
63.8(e). The copies shall be furnished at least 15 calendar days before
the performance test required under Sec. 63.7 is conducted.
(3) Excess emissions and continuous monitoring system performance
report and summary report. (i) Excess emissions and parameter monitoring
exceedances are defined in relevant standards. The owner or operator of
an affected source required to install a CMS by a relevant standard
shall submit an excess emissions and continuous monitoring system
performance report and/or a summary report to the Administrator
semiannually, except when--
(A) More frequent reporting is specifically required by a relevant
standard;
(B) The Administrator determines on a case-by-case basis that more
frequent reporting is necessary to accurately assess the compliance
status of the source; or
(C) [Reserved]
[[Page 62]]
(D) The affected source is complying with the Performance Track
Provisions of Sec. 63.16, which allows less frequent reporting.
(ii) Request to reduce frequency of excess emissions and continuous
monitoring system performance reports. Notwithstanding the frequency of
reporting requirements specified in paragraph (e)(3)(i) of this section,
an owner or operator who is required by a relevant standard to submit
excess emissions and continuous monitoring system performance (and
summary) reports on a quarterly (or more frequent) basis may reduce the
frequency of reporting for that standard to semiannual if the following
conditions are met:
(A) For 1 full year (e.g., 4 quarterly or 12 monthly reporting
periods) the affected source's excess emissions and continuous
monitoring system performance reports continually demonstrate that the
source is in compliance with the relevant standard;
(B) The owner or operator continues to comply with all recordkeeping
and monitoring requirements specified in this subpart and the relevant
standard; and
(C) The Administrator does not object to a reduced frequency of
reporting for the affected source, as provided in paragraph (e)(3)(iii)
of this section.
(iii) The frequency of reporting of excess emissions and continuous
monitoring system performance (and summary) reports required to comply
with a relevant standard may be reduced only after the owner or operator
notifies the Administrator in writing of his or her intention to make
such a change and the Administrator does not object to the intended
change. In deciding whether to approve a reduced frequency of reporting,
the Administrator may review information concerning the source's entire
previous performance history during the 5-year recordkeeping period
prior to the intended change, including performance test results,
monitoring data, and evaluations of an owner or operator's conformance
with operation and maintenance requirements. Such information may be
used by the Administrator to make a judgment about the source's
potential for noncompliance in the future. If the Administrator
disapproves the owner or operator's request to reduce the frequency of
reporting, the Administrator will notify the owner or operator in
writing within 45 days after receiving notice of the owner or operator's
intention. The notification from the Administrator to the owner or
operator will specify the grounds on which the disapproval is based. In
the absence of a notice of disapproval within 45 days, approval is
automatically granted.
(iv) As soon as CMS data indicate that the source is not in
compliance with any emission limitation or operating parameter specified
in the relevant standard, the frequency of reporting shall revert to the
frequency specified in the relevant standard, and the owner or operator
shall submit an excess emissions and continuous monitoring system
performance (and summary) report for the noncomplying emission points at
the next appropriate reporting period following the noncomplying event.
After demonstrating ongoing compliance with the relevant standard for
another full year, the owner or operator may again request approval from
the Administrator to reduce the frequency of reporting for that
standard, as provided for in paragraphs (e)(3)(ii) and (e)(3)(iii) of
this section.
(v) Content and submittal dates for excess emissions and monitoring
system performance reports. All excess emissions and monitoring system
performance reports and all summary reports, if required, shall be
delivered or postmarked by the 30th day following the end of each
calendar half or quarter, as appropriate. Written reports of excess
emissions or exceedances of process or control system parameters shall
include all the information required in paragraphs (c)(5) through
(c)(13) of this section, in Sec. Sec. 63.8(c)(7) and 63.8(c)(8), and in
the relevant standard, and they shall contain the name, title, and
signature of the responsible official who is certifying the accuracy of
the report. When no excess emissions or exceedances of a parameter have
occurred, or a CMS has not been inoperative, out of control, repaired,
or adjusted, such information shall be stated in the report.
(vi) Summary report. As required under paragraphs (e)(3)(vii) and
[[Page 63]]
(e)(3)(viii) of this section, one summary report shall be submitted for
the hazardous air pollutants monitored at each affected source (unless
the relevant standard specifies that more than one summary report is
required, e.g., one summary report for each hazardous air pollutant
monitored). The summary report shall be entitled ``Summary Report--
Gaseous and Opacity Excess Emission and Continuous Monitoring System
Performance'' and shall contain the following information:
(A) The company name and address of the affected source;
(B) An identification of each hazardous air pollutant monitored at
the affected source;
(C) The beginning and ending dates of the reporting period;
(D) A brief description of the process units;
(E) The emission and operating parameter limitations specified in
the relevant standard(s);
(F) The monitoring equipment manufacturer(s) and model number(s);
(G) The date of the latest CMS certification or audit;
(H) The total operating time of the affected source during the
reporting period;
(I) An emission data summary (or similar summary if the owner or
operator monitors control system parameters), including the total
duration of excess emissions during the reporting period (recorded in
minutes for opacity and hours for gases), the total duration of excess
emissions expressed as a percent of the total source operating time
during that reporting period, and a breakdown of the total duration of
excess emissions during the reporting period into those that are due to
startup/shutdown, control equipment problems, process problems, other
known causes, and other unknown causes;
(J) A CMS performance summary (or similar summary if the owner or
operator monitors control system parameters), including the total CMS
downtime during the reporting period (recorded in minutes for opacity
and hours for gases), the total duration of CMS downtime expressed as a
percent of the total source operating time during that reporting period,
and a breakdown of the total CMS downtime during the reporting period
into periods that are due to monitoring equipment malfunctions,
nonmonitoring equipment malfunctions, quality assurance/quality control
calibrations, other known causes, and other unknown causes;
(K) A description of any changes in CMS, processes, or controls
since the last reporting period;
(L) The name, title, and signature of the responsible official who
is certifying the accuracy of the report; and
(M) The date of the report.
(vii) If the total duration of excess emissions or process or
control system parameter exceedances for the reporting period is less
than 1 percent of the total operating time for the reporting period, and
CMS downtime for the reporting period is less than 5 percent of the
total operating time for the reporting period, only the summary report
shall be submitted, and the full excess emissions and continuous
monitoring system performance report need not be submitted unless
required by the Administrator.
(viii) If the total duration of excess emissions or process or
control system parameter exceedances for the reporting period is 1
percent or greater of the total operating time for the reporting period,
or the total CMS downtime for the reporting period is 5 percent or
greater of the total operating time for the reporting period, both the
summary report and the excess emissions and continuous monitoring system
performance report shall be submitted.
(4) Reporting continuous opacity monitoring system data produced
during a performance test. The owner or operator of an affected source
required to use a COMS shall record the monitoring data produced during
a performance test required under Sec. 63.7 and shall furnish the
Administrator a written report of the monitoring results. The report of
COMS data shall be submitted simultaneously with the report of the
performance test results required in paragraph (d)(2) of this section.
(f) Waiver of recordkeeping or reporting requirements. (1) Until a
waiver of a recordkeeping or reporting requirement has been granted by
the Administrator
[[Page 64]]
under this paragraph, the owner or operator of an affected source
remains subject to the requirements of this section.
(2) Recordkeeping or reporting requirements may be waived upon
written application to the Administrator if, in the Administrator's
judgment, the affected source is achieving the relevant standard(s), or
the source is operating under an extension of compliance, or the owner
or operator has requested an extension of compliance and the
Administrator is still considering that request.
(3) If an application for a waiver of recordkeeping or reporting is
made, the application shall accompany the request for an extension of
compliance under Sec. 63.6(i), any required compliance progress report
or compliance status report required under this part (such as under
Sec. Sec. 63.6(i) and 63.9(h)) or in the source's title V permit, or an
excess emissions and continuous monitoring system performance report
required under paragraph (e) of this section, whichever is applicable.
The application shall include whatever information the owner or operator
considers useful to convince the Administrator that a waiver of
recordkeeping or reporting is warranted.
(4) The Administrator will approve or deny a request for a waiver of
recordkeeping or reporting requirements under this paragraph when he/
she--
(i) Approves or denies an extension of compliance; or
(ii) Makes a determination of compliance following the submission of
a required compliance status report or excess emissions and continuous
monitoring systems performance report; or
(iii) Makes a determination of suitable progress towards compliance
following the submission of a compliance progress report, whichever is
applicable.
(5) A waiver of any recordkeeping or reporting requirement granted
under this paragraph may be conditioned on other recordkeeping or
reporting requirements deemed necessary by the Administrator.
(6) Approval of any waiver granted under this section shall not
abrogate the Administrator's authority under the Act or in any way
prohibit the Administrator from later canceling the waiver. The
cancellation will be made only after notice is given to the owner or
operator of the affected source.

Sec. 63.11 Control device and work practice requirements.
(a) Applicability. (1) The applicability of this section is set out
in Sec. 63.1(a)(4).
(2) This section contains requirements for control devices used to
comply with applicable subparts of this part. The requirements are
placed here for administrative convenience and apply only to facilities
covered by subparts referring to this section.
(3) This section also contains requirements for an alternative work
practice used to identify leaking equipment. This alternative work
practice is placed here for administrative convenience and is available
to all subparts in 40 CFR parts 60, 61, 63, and 65 that require
monitoring of equipment with a 40 CFR part 60, appendix A-7, Method 21
monitor.
(b) Flares. (1) Owners or operators using flares to comply with the
provisions of this part shall monitor these control devices to assure
that they are operated and maintained in conformance with their designs.
Applicable subparts will provide provisions stating how owners or
operators using flares shall monitor these control devices.
(2) Flares shall be steam-assisted, air-assisted, or non-assisted.
(3) Flares shall be operated at all times when emissions may be
vented to them.
(4) Flares shall be designed for and operated with no visible
emissions, except for periods not to exceed a total of 5 minutes during
any 2 consecutive hours. Test Method 22 in appendix A of part 60 of this
chapter shall be used to determine the compliance of flares with the
visible emission provisions of this part. The observation period is 2
hours and shall be used according to Method 22.
(5) Flares shall be operated with a flame present at all times. The
presence of a flare pilot flame shall be monitored using a thermocouple
or any
[[Page 65]]
other equivalent device to detect the presence of a flame.
(6) An owner/operator has the choice of adhering to the heat content
specifications in paragraph (b)(6)(ii) of this section, and the maximum
tip velocity specifications in paragraph (b)(7) or (b)(8) of this
section, or adhering to the requirements in paragraph (b)(6)(i) of this
section.
(i)(A) Flares shall be used that have a diameter of 3 inches or
greater, are nonassisted, have a hydrogen content of 8.0 percent (by
volume) or greater, and are designed for and operated with an exit
velocity less than 37.2 m/sec (122 ft/sec) and less than the velocity
Vmax, as determined by the following equation:
Vmax = (XH2-K1)* K2
Where:
Vmax = Maximum permitted velocity, m/sec.
K1 = Constant, 6.0 volume-percent hydrogen.
K2 = Constant, 3.9(m/sec)/volume-percent hydrogen.
XH2 = The volume-percent of hydrogen, on a wet basis, as
calculated by using the American Society for Testing and
Materials (ASTM) Method D1946-77. (Incorporated by reference
as specified in Sec. 63.14).
(B) The actual exit velocity of a flare shall be determined by the
method specified in paragraph (b)(7)(i) of this section.
(ii) Flares shall be used only with the net heating value of the gas
being combusted at 11.2 MJ/scm (300 Btu/scf) or greater if the flare is
steam-assisted or air-assisted; or with the net heating value of the gas
being combusted at 7.45 M/scm (200 Btu/scf) or greater if the flares is
non-assisted. The net heating value of the gas being combusted in a
flare shall be calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR04MY98.004
Where:
HT = Net heating value of the sample, MJ/scm; where the net
enthalpy per mole of offgas is based on combustion at 25
[deg]C and 760 mm Hg, but the standard temperature for
determining the volume corresponding to one mole is 20 [deg]C.
K = Constant =
[GRAPHIC] [TIFF OMITTED] TR04MY98.005
where the standard temperature for (g-mole/scm) is 20 [deg]C.
Ci = Concentration of sample component i in ppmv on a wet
basis, as measured for organics by Test Method 18 and measured
for hydrogen and carbon monoxide by American Society for
Testing and Materials (ASTM) D1946-77 or 90 (Reapproved 1994)
(incorporated by reference as specified in Sec. 63.14).
Hi = Net heat of combustion of sample component i, kcal/g-
mole at 25 [deg]C and 760 mm Hg. The heats of combustion may
be determined using ASTM D2382-76 or 88 or D4809-95
(incorporated by reference as specified in Sec. 63.14) if
published values are not available or cannot be calculated.
n = Number of sample components.
(7)(i) Steam-assisted and nonassisted flares shall be designed for
and operated with an exit velocity less than 18.3 m/sec (60 ft/sec),
except as provided in paragraphs (b)(7)(ii) and (b)(7)(iii) of this
section. The actual exit velocity of a flare shall be determined by
dividing by the volumetric flow rate of gas being combusted (in units of
emission standard temperature and pressure), as determined by Test
Method 2, 2A, 2C, or 2D in appendix A to 40 CFR part 60 of this chapter,
as appropriate, by the unobstructed (free) cross-sectional area of the
flare tip.
(ii) Steam-assisted and nonassisted flares designed for and operated
with an exit velocity, as determined by the method specified in
paragraph (b)(7)(i) of this section, equal to or greater than 18.3 m/sec
(60 ft/sec) but less than 122 m/sec (400 ft/sec), are allowed if the net
heating value of the gas being combusted is greater than 37.3 MJ/scm
(1,000 Btu/scf).
(iii) Steam-assisted and nonassisted flares designed for and
operated with an exit velocity, as determined by the method specified in
paragraph (b)(7)(i) of this section, less than the velocity
Vmax, as determined by the method specified in this
paragraph, but less than 122 m/sec (400 ft/sec) are allowed. The maximum
permitted velocity, Vmax, for flares complying with this
paragraph shall be determined by the following equation:
Log10(Vmax) = (HT + 28.8)/31.7
[[Page 66]]
Where:
Vmax = Maximum permitted velocity, m/sec.
28.8 = Constant.
31.7 = Constant.
HT = The net heating value as determined in paragraph (b)(6)
of this section.
(8) Air-assisted flares shall be designed and operated with an exit
velocity less than the velocity Vmax. The maximum permitted
velocity, Vmax, for air-assisted flares shall be determined
by the following equation:
Vmax = 8.71 + 0.708(HT)
Where:
Vmax = Maximum permitted velocity, m/sec.
8.71 = Constant.
0.708 = Constant.
HT = The net heating value as determined in paragraph
(b)(6)(ii) of this section.
(c) Alternative work practice for monitoring equipment for leaks.
Paragraphs (c), (d), and (e) of this section apply to all equipment for
which the applicable subpart requires monitoring with a 40 CFR part 60,
appendix A-7, Method 21 monitor, except for closed vent systems,
equipment designated as leakless, and equipment identified in the
applicable subpart as having no detectable emissions, as indicated by an
instrument reading of less than 500 ppm above background. An owner or
operator may use an optical gas imaging instrument instead of a 40 CFR
part 60, sppendix A-7, Method 21 monitor. Requirements in the existing
subparts that are specific to the Method 21 instrument do not apply
under this section. All other requirements in the applicable subpart
that are not addressed in paragraphs (c), (d), and (e) of this section
continue to apply. For example, equipment specification requirements,
and non-Method 21 instrument recordkeeping and reporting requirements in
the applicable subpart continue to apply. The terms defined in
paragraphs (c)(1) through (5) of this section have meanings that are
specific to the alternative work practice standard in paragraphs (c),
(d), and (e) of this section.
(1) Applicable subpart means the subpart in 40 CFR parts 60, 61, 63,
and 65 that requires monitoring of equipment with a 40 CFR part 60,
appendix A-7, Method 21 monitor.
(2) Equipment means pumps, valves, pressure relief valves,
compressors, open-ended lines, flanges, connectors, and other equipment
covered by the applicable subpart that require monitoring with a 40 CFR
part 60, appendix A-7, Method 21 monitor.
(3) Imaging means making visible emissions that may otherwise be
invisible to the naked eye.
(4) Optical gas imaging instrument means an instrument that makes
visible emissions that may otherwise be invisible to the naked eye.
(5) Repair means that equipment is adjusted, or otherwise altered,
in order to eliminate a leak.
(6) Leak means:
(i) Any emissions imaged by the optical gas instrument;
(ii) Indications of liquids dripping;
(iii) Indications by a sensor that a seal or barrier fluid system
has failed; or
(iv) Screening results using a 40 CFR part 60, appendix A-7, Method
21 monitor that exceed the leak definition in the applicable subpart to
which the equipment is subject.
(d) The alternative work practice standard for monitoring equipment
for leaks is available to all subparts in 40 CFR parts 60, 61, 63, and
65 that require monitoring of equipment with a 40 CFR part 60, appendix
A-7, Method 21 monitor.
(1) An owner or operator of an affected source subject to 40 CFR
parts 60, 61, 63, or 65 can choose to comply with the alternative work
practice requirements in paragraph (e) of this section instead of using
the 40 CFR part 60, appendix A-7, Method 21 monitor to identify leaking
equipment. The owner or operator must document the equipment, process
units, and facilities for which the alternative work practice will be
used to identify leaks.
(2) Any leak detected when following the leak survey procedure in
paragraph (e)(3) of this section must be identified for repair as
required in the applicable subpart.
(3) If the alternative work practice is used to identify leaks, re-
screening after an attempted repair of leaking equipment must be
conducted using either the alternative work practice or the 40 CFR part
60, Appendix A-7,
[[Page 67]]
Method 21 monitor at the leak definition required in the applicable
subparts to which the equipment is subject.
(4) The schedule for repair is as required in the applicable
subpart.
(5) When this alternative work practice is used for detecting
leaking equipment, choose one of the monitoring frequencies listed in
Table 1 to subpart A of this part in lieu of the monitoring frequency
specified for regulated equipment in the applicable subpart. Reduced
monitoring frequencies for good performance are not applicable when
using the alternative work practice.
(6) When this alternative work practice is used for detecting
leaking equipment, the following are not applicable for the equipment
being monitored:
(i) Skip period leak detection and repair;
(ii) Quality improvement plans; or
(iii) Complying with standards for allowable percentage of valves
and pumps to leak.
(7) When the alternative work practice is used to detect leaking
equipment, the regulated equipment in paragraph (d)(1)(i) of this
section must also be monitored annually using a 40 CFR part 60, Appendix
A-7, Method 21 monitor at the leak definition required in the applicable
subpart. The owner or operator may choose the specific monitoring period
(for example, first quarter) to conduct the annual monitoring.
Subsequent monitoring must be conducted every 12 months from the initial
period. Owners or operators must keep records of the annual Method 21
screening results, as specified in paragraph (i)(4)(vii) of this
section.
(e) An owner or operator of an affected source who chooses to use
the alternative work practice must comply with the requirements of
paragraphs (e)(1) through (e)(5) of this section.
(1) Instrument specifications. The optical gas imaging instrument
must comply with the requirements specified in paragraphs (e)(1)(i) and
(e)(1)(ii) of this section.
(i) Provide the operator with an image of the potential leak points
for each piece of equipment at both the detection sensitivity level and
within the distance used in the daily instrument check described in
paragraph (e)(2) of this section. The detection sensitivity level
depends upon the frequency at which leak monitoring is to be performed.
(ii) Provide a date and time stamp for video records of every
monitoring event.
(2) Daily instrument check. On a daily basis, and prior to beginning
any leak monitoring work, test the optical gas imaging instrument at the
mass flow rate determined in paragraph (e)(2)(i) of this section in
accordance with the procedure specified in paragraphs (e)(2)(ii) through
(e)(2)(iv) of this section for each camera configuration used during
monitoring (for example, different lenses used), unless an alternative
method to demonstrate daily instrument checks has been approved in
accordance with paragraph (e)(2)(v) of this section.
(i) Calculate the mass flow rate to be used in the daily instrument
check by following the procedures in paragraphs (e)(2)(i)(A) and
(e)(2)(i)(B) of this section.
(A) For a specified population of equipment to be imaged by the
instrument, determine the piece of equipment in contact with the lowest
mass fraction of chemicals that are detectable, within the distance to
be used in paragraph (e)(2)(iv)(B) of this section, at or below the
standard detection sensitivity level.
(B) Multiply the standard detection sensitivity level, corresponding
to the selected monitoring frequency in Table 1 of subpart A of this
part, by the mass fraction of detectable chemicals from the stream
identified in paragraph (e)(2)(i)(A) of this section to determine the
mass flow rate to be used in the daily instrument check, using the
following equation.
[GRAPHIC] [TIFF OMITTED] TR22DE08.008
Where:
Edic = Mass flow rate for the daily instrument check, grams
per hour
xi = Mass fraction of detectable chemical(s) i seen by the
optical gas imaging instrument, within the distance to be used
in paragraph (e)(2)(iv)(B) of this section, at or below the
standard detection sensitivity level, Esds.
[[Page 68]]
Esds = Standard detection sensitivity level from Table 1 to
subpart A, grams per hour
k = Total number of detectable chemicals emitted from the leaking
equipment and seen by the optical gas imaging instrument.
(ii) Start the optical gas imaging instrument according to the
manufacturer's instructions, ensuring that all appropriate settings
conform to the manufacturer's instructions.
(iii) Use any gas chosen by the user that can be viewed by the
optical gas imaging instrument and that has a purity of no less than 98
percent.
(iv) Establish a mass flow rate by using the following procedures:
(A) Provide a source of gas where it will be in the field of view of
the optical gas imaging instrument.
(B) Set up the optical gas imaging instrument at a recorded distance
from the outlet or leak orifice of the flow meter that will not be
exceeded in the actual performance of the leak survey. Do not exceed the
operating parameters of the flow meter.
(C) Open the valve on the flow meter to set a flow rate that will
create a mass emission rate equal to the mass rate calculated in
paragraph (e)(2)(i) of this section while observing the gas flow through
the optical gas imaging instrument viewfinder. When an image of the gas
emission is seen through the viewfinder at the required emission rate,
make a record of the reading on the flow meter.
(v) Repeat the procedures specified in paragraphs (e)(2)(ii) through
(e)(2)(iv) of this section for each configuration of the optical gas
imaging instrument used during the leak survey.
(vi) To use an alternative method to demonstrate daily instrument
checks, apply to the Administrator for approval of the alternative under
Sec. 63.177 or Sec. 63.178, whichever is applicable.
(3) Leak survey procedure. Operate the optical gas imaging
instrument to image every regulated piece of equipment selected for this
work practice in accordance with the instrument manufacturer's operating
parameters. All emissions imaged by the optical gas imaging instrument
are considered to be leaks and are subject to repair. All emissions
visible to the naked eye are also considered to be leaks and are subject
to repair.
(4) Recordkeeping. Keep the records described in paragraphs
(e)(4)(i) through (e)(4)(vii) of this section:
(i) The equipment, processes, and facilities for which the owner or
operator chooses to use the alternative work practice.
(ii) The detection sensitivity level selected from Table 1 to
subpart A of this part for the optical gas imaging instrument.
(iii) The analysis to determine the piece of equipment in contact
with the lowest mass fraction of chemicals that are detectable, as
specified in paragraph (e)(2)(i)(A) of this section.
(iv) The technical basis for the mass fraction of detectable
chemicals used in the equation in paragraph (e)(2)(i)(B) of this
section.
(v) The daily instrument check. Record the distance, per paragraph
(e)(2)(iv)(B) of this section, and the flow meter reading, per paragraph
(e)(2)(iv)(C) of this section, at which the leak was imaged. Keep a
video record of the daily instrument check for each configuration of the
optical gas imaging instrument used during the leak survey (for example,
the daily instrument check must be conducted for each lens used). The
video record must include a time and date stamp for each daily
instrument check. The video record must be kept for 5 years.
(vi) Recordkeeping requirements in the applicable subpart. A video
record must be used to document the leak survey results. The video
record must include a time and date stamp for each monitoring event. A
video record can be used to meet the recordkeeping requirements of the
applicable subparts if each piece of regulated equipment selected for
this work practice can be identified in the video record. The video
record must be kept for 5 years.
(vii) The results of the annual Method 21 screening required in
paragraph (h)(7) of this section. Records must be kept for all regulated
equipment specified in paragraph (h)(1) of this section. Records must
identify the equipment screened, the screening value measured by Method
21, the time and date of the screening, and calibration information
[[Page 69]]
required in the existing applicable subparts.

at the same site as the process or production unit;
(ii) (A) The permitting authority has determined within a period of
5 years prior to the fabrication, erection, or installation of the
process or production unit that the existing emission control equipment
represented best available control technology (BACT), lowest achievable
emission rate (LAER) under 40 CFR part 51 or 52, toxics--best available
control technology (T-BACT), or MACT based on State air toxic rules for
the category of pollutants which includes those HAP's to be emitted by
the process or production unit; or
(B) The permitting authority determines that the control of HAP
emissions provided by the existing equipment will be equivalent to that
level of control currently achieved by other
[[Page 85]]
well-controlled similar sources (i.e., equivalent to the level of
control that would be provided by a current BACT, LAER, T-BACT, or State
air toxic rule MACT determination);
(iii) The permitting authority determines that the percent control
efficiency for emissions of HAP from all sources to be controlled by the
existing control equipment will be equivalent to the percent control
efficiency provided by the control equipment prior to the inclusion of
the new process or production unit;
(iv) The permitting authority has provided notice and an opportunity
for public comment concerning its determination that criteria in
paragraphs (2)(i), (2)(ii), and (2)(iii) of this definition apply and
concerning the continued adequacy of any prior LAER, BATC, T-BACT, or
State air toxic rule MACT determination;
(v) If any commenter has asserted that a prior LAER, BACT, T-BACT,
or State air toxic rule MACT determination is no longer adequate, the
permitting authority has determined that the level of control required
by that prior determination remains adequate; and
(vi) Any emission limitations, work practice requirements, or other
terms and conditions upon which the above determinations by the
permitting authority are applicable requirements under section 504(a)
and either have been incorporated into any existing title V permit for
the affected facility or will be incorporated into such permit upon
issuance.

utility power distribution system for sale shall be considered an
electric utility steam generating unit.
Greenfield suite means a contiguous area under common control that
is an undeveloped site.
List of Source Categories means the Source Category List required by
section 112(c) of the Act.
Maximum achievable control technology (MACT) emission limitation for
new sources means the emission limitation which is not less stringent
that the emission limitation achieved in practice by the best controlled
similar source, and which reflects the maximum degree of deduction in
emissions that the permitting authority, taking into consideration the
cost of achieving such emission reduction, and any non-air quality
health and environmental impacts and energy requirements, determines is
achievable by the constructed or reconstructed major source.

Similar source means a stationary source or process that has
comparable emissions and is structurally similar in design and capacity
to a constructed or reconstructed major source such that the source
could be controlled using the same control technology.
[61 FR 68399, Dec. 27, 1996]
Sec. 63.42 Program requirements governing construction
or reconstruction of major sources.
(a) Adoption of program. Each permitting authority shall review its
existing programs, procedures, and criteria for preconstruction review
for conformity to the requirements established by Sec. Sec. 63.40
through 63.44, shall make any additions and revisions to its existing
programs, procedures, and criteria that the permitting authority deems
necessary to properly effectuate Sec. Sec. 63.40 through 63.44, and
shall adopt a program to implement section 112(g) with respect to
construction or reconstruction of major sources of HAP. As part of the
adoption by the permitting authority of a program to implement section
112(g) with respect to construction or reconstruction of major sources
of HAP, the chief executive officer of the permitting authority shall
certify that the program satisfies all applicable requirements
established by Sec. Sec. 63.40 through 63.44, and shall specify an
effective date for that program which is not later than June 29, 1998.
Prior to the specified effective date, the permitting authority shall
publish a notice stating that the permitting authority has adopted a
program to implement section 112(g) with respect to construction or
reconstruction of major sources of HAP and stating the effective date,
and shall provide a written description of the program to the
Administrator through the appropriate EPA Regional Office. Nothing in
this section shall be construed either:
(1) To require that any owner or operator of a stationary source
comply with any requirement adopted by the permitting authority which is
not intended to implement section 112(g) with respect to construction or
reconstruction of major sources of HAP; or
(2) To preclude the permitting authority from enforcing any
requirements not intended to implement section 112(g) with respect to
construction or reconstruction of major sources of HAP under any other
provision of applicable law.
(b) Failure to adopt program. In the event that the permitting
authority fails to adopt a program to implement section 112(g) with
respect to construction or reconstruction of major sources of HAP with
an effective date on or before June 29, 1998, and the permitting
authority concludes that it is able to make case-by-case MACT
determinations which conform to the provisions of Sec. 63.43 in the
absence of such a program, the permitting authority may elect to make
such determinations. However, in those instances where the permitting
authority elects to make case-by-case MACT determinations in the absence
of a program to implement
[[Page 87]]
section 112(g) with respect to construction or reconstruction of major
sources of HAP, no such case-by-case MACT determination shall take
effect until after it has been submitted by the permitting authority in
writing to the appropriate EPA Regional Adminstrator and the EPA
Regional Administrator has concurred in writing that the case-by-case
MACT determination by the permitting authority is in conformity with all
requirements established by Sec. Sec. 63.40 through 63.44. In the event
that the permitting authority fails to adopt a program to implement
section 112(g) with respect to construction or reconstruction of major
sources of HAP with an effective date on or before June 29, 1998, and
the permitting authority concludes that it is unable to make case-by-
case MACT determinations in the absence of such a program, the
permitting authority may request that the EPA Regional Administrator
implement a transitional program to implement section 112(g) with
respect to construction or reconstruction of major sources of HAP in the
affected State of local jurisdiction while the permitting authority
completes development and adoption of a section 112(g) program. Any such
transitional section 112(g) program implemented by the EPA Regional
Administrator shall conform to all requirements established by
Sec. Sec. 63.40 through 63.44, and shall remain in effect for no more
than 30 months. Continued failure by the permitting authority to adopt a
program to implement section 112(g) with respect to construction or
reconstruction of major sources of HAP shall be construed as a failure
by the permitting authority to adequately administer and enforce its
title V permitting program and shall constitute cause by EPA to apply
the sanctions and remedies set forth in the Clean Air Act section
502(I).
(c) Prohibition. After the effective date of section 112(g)(2)(B)
(as defined in Sec. 63.41) in a State or local jurisdiction and the
effective date of the title V permit program applicable to that State or
local jurisdiction, no person may begin actual construction or
reconstruction of a major source of HAP in such State or local
jurisdiction unless:
(1) The major source in question has been specifically regulated or
exempted from regulation under a standard issued pursuant to section
112(d), section 112(h) or section 112(j) in part 63, and the owner and
operator has fully complied with all procedures and requirements for
preconstruction review established by that standard, including any
applicable requirements set forth in subpart A of this part 63; or
(2) The permitting authority has made a final and effective case-by-
case determination pursuant to the provisions of Sec. 63.43 such that
emissions from the constructed or reconstructed major source will be
controlled to a level no less stringent than the maximum achievable
control technology emission limitation for new sources.
[61 FR 68400, Dec. 27, 1996, as amended at 64 FR 35032, June 30, 1999]
Sec. 63.43 Maximum achievable control technology (MACT) determinations
for constructed and reconstructed major sources.
(a) Applicability. The requirements of this section apply to an
owner or operator who constructs or reconstructs a major source of HAP
subject to a case-by-case determination of maximum achievable control
technology pursuant to Sec. 63.42(c).
(b) Requirements for constructed and reconstructed major sources.
When a case-by-case determination of MACT is required by Sec. 63.42(c),
the owner and operator shall obtain from the permitting authority an
approved MACT determination according to one of the review options
contained in paragraph (c) of this section.
(c) Review options. (1) When the permitting authority requires the
owner or operator to obtain, or revise, a permit issued pursuant to
title V of the Act before construction or reconstruction of the major
source, or when the permitting authority allows the owner or operator at
its discretion to obtain or revise such a permit before construction or
reconstruction, and the owner or operator elects that option, the owner
or operator shall follow the administrative procedures in the program
approved under title V of the Act
[[Page 88]]
(or in other regulations issued pursuant to title V of the Act, where
applicable).
(2) When an owner or operator is not required to obtain or revise a
title V permit (or other permit issued pursuant to title V of the Act)
before construction or reconstruction, the owner or operator (unless the
owner or operator voluntarily follows the process to obtain a title V
permit) shall either, at the discretion of the permitting authority:
(i) Apply for and obtain a Notice of MACT Approval according to the
procedures outlined in paragraphs (f) through (h) of this section; or
(ii) Apply for a MACT determination under any other administrative
procedures for preconstruction review and approval established by the
permitting authority for a State or local jurisdiction which provide for
public participation in the determination, and ensure that no person may
begin actual construction or reconstruction of a major source in that
State or local jurisdiction unless the permitting authority determines
that the MACT emission limitation for new sources will be met.
(3) When applying for a permit pursuant to title V of the Act, an
owner or operator may request approval of case-by-case MACT
determinations for alternative operating scenarios. Approval of such
determinations satisfies the requirements of section 112(g) of each such
scenario.
(4) Regardless of the review process, the MACT emission limitation
and requirements established shall be effective as required by paragraph
(j) of this section, consistent with the principles established in
paragraph (d) of this section, and supported by the information listed
in paragraph (e) of this section. The owner or operator shall comply
with the requirements in paragraphs (k) and (l) of this section, and
with all applicable requirements in subpart A of this part.
(d) Principles of MACT determinations. The following general
principles shall govern preparation by the owner or operator of each
permit application or other application requiring a case-by-case MACT
determination concerning construction or reconstruction of a major
source, and all subsequent review of and actions taken concerning such
an application by the permitting authority:
(1) The MACT emission limitation or MACT requirements recommended by
the applicant and approved by the permitting authority shall not be less
stringent than the emission control which is achieved in practice by the
best controlled similar source, as determined by the permitting
authority.
(2) Based upon available information, as defined in this subpart,
the MACT emission limitation and control technology (including any
requirements under paragraph (d)(3) of this section) recommended by the
applicant and approved by the permitting authority shall achieve the
maximum degree of reduction in emissions of HAP which can be achieved by
utilizing those control technologies that can be identified from the
available information, taking into consideration the costs of achieving
such emission reduction and any non-air quality health and environmental
impacts and energy requirements associated with the emission reduction.
(3) The applicant may recommend a specific design, equipment, work
practice, or operational standard, or a combination thereof, and the
permitting authority may approve such a standard if the permitting
authority specifically determines that it is not feasible to prescribe
or enforce an emission limitation under the criteria set forth in
section 112(h)(2) of the Act.
(4) If the Administrator has either proposed a relevant emission
standard pursuant to section 112(d) or section 112(h) of the Act or
adopted a presumptive MACT determination for the source category which
includes the constructed or reconstructed major source, then the MACT
requirements applied to the constructed or reconstructed major source
shall have considered those MACT emission limitations and requirements
of the proposed standard or presumptive MACT determination.
(e) Application requirements for a case-by-case MACT determination.
(1) An application for a MACT determination (whether a permit
application under title V of the Act, an application for a Notice of
MACT Approval, or other
[[Page 89]]
document specified by the permitting authority under paragraph
(c)(2)(ii) of this section) shall specify a control technology selected
by the owner or operator that, if properly operated and maintained, will
meet the MACT emission limitation or standard as determined according to
the principles set forth in paragraph (d) of this section.
(2) In each instance where a constructed or reconstructed major
source would require additional control technology or a change in
control technology, the application for a MACT determination shall
contain the following information:
(i) The name and address (physical location) of the major source to
be constructed or reconstructed;
(ii) A brief description of the major source to be constructed or
reconstructed and identification of any listed source category or
categories in which it is included;
(iii) The expected commencement date for the construction or
reconstruction of the major source;
(iv) The expected completion date for construction or reconstruction
of the major source;
(v) the anticipated date of start-up for the constructed or
reconstructed major source;
(vi) The HAP emitted by the constructed or reconstructed major
source, and the estimated emission rate for each such HAP, to the extent
this information is needed by the permitting authority to determine
MACT;
(vii) Any federally enforceable emission limitations applicable to
the constructed or reconstructed major source;
(viii) The maximum and expected utilization of capacity of the
constructed or reconstructed major source, and the associated
uncontrolled emission rates for that source, to the extent this
information is needed by the permitting authority to determine MACT;
(ix) The controlled emissions for the constructed or reconstructed
major source in tons/yr at expected and maximum utilization of capacity,
to the extent this information is needed by the permitting authority to
determine MACT;
(x) A recommended emission limitation for the constructed or
reconstructed major source consistent with the principles set forth in
paragraph (d) of this section;
(xi) The selected control technology to meet the recommended MACT
emission limitation, including technical information on the design,
operation, size, estimated control efficiency of the control technology
(and the manufacturer's name, address, telephone number, and relevant
specifications and drawings, if requested by the permitting authority);
(xii) Supporting documentation including identification of
alternative control technologies considered by the applicant to meet the
emission limitation, and analysis of cost and non-air quality health
environmental impacts or energy requirements for the selected control
technology; and
(xiii) Any other relevant information required pursuant to subpart
A.
(3) In each instance where the owner or operator contends that a
constructed or reconstructed major source will be in compliance, upon
startup, with case-by-case MACT under this subpart without a change in
control technology, the application for a MACT determination shall
contain the following information:
(i) The information described in paragraphs (e)(2)(i) through
(e)(2)(x) of this section; and
(ii) Documentation of the control technology in place.
(f) Administrative procedures for review of the Notice of MACT
Approval. (1) The permitting authority will notify the owner or operator
in writing, within 45 days from the date the application is first
received, as to whether the application for a MACT determination is
complete or whether additional information is required.
(2) The permitting authority will initially approve the recommended
MACT emission limitation and other terms set forth in the application,
or the permitting authority will notify the owner or operator in writing
of its intent to disapprove the application, within 30 calendar days
after the owner or operator is notified in writing that the application
is complete.
[[Page 90]]
(3) The owner or operator may present, in writing, within 60
calendar days after receipt of notice of the permitting authority's
intent to disapprove the application, additional information or
arguments pertaining to, or amendments to, the application for
consideration by the permitting authority before it decides whether to
finally disapprove the application.
(4) The permitting authority will either initially approve or issue
a final disapproval of the application within 90 days after it notifies
the owner or operator of an intent to disapprove or within 30 days after
the date additional information is received from the owner or operator;
whichever is earlier.
(5) A final determination by the permitting authority to disapprove
any application will be in writing and will specify the grounds on which
the disapproval is based. If any application is finally disapproved, the
owner or operator may submit a subsequent application concerning
construction or reconstruction of the same major source, provided that
the subsequent application has been amended in response to the stated
grounds for the prior disapproval.
(6) An initial decision to approve an application for a MACT
determination will be set forth in the Notice of MACT Approval as
described in paragraph (g) of this section.
(g) Notice of MACT Approval. (1) The Notice of MACT Approval will
contain a MACT emission limitation (or a MACT work practice standard if
the permitting authority determines it is not feasible to prescribe or
enforce an emission standard) to control the emissions of HAP. The MACT
emission limitation or standard will be determined by the permitting
authority and will conform to the principles set forth in paragraph (d)
of this section.
(2) The Notice of MACT Approval will specify any notification,
operation and maintenance, performance testing, monitoring, reporting
and record keeping requirements. The Notice of MACT Approval shall
include:

practice standard established under this subpart, additional emission
limits, production limits, operational limits or other terms and
conditions necessary to ensure Federal enforceability of the MACT
emission limitation;
(ii) Compliance certifications, testing, monitoring, reporting and
record keeping requirements that are consistent with the requirements of
Sec. 70.6(c) of this chapter;
(iii) In accordance with section 114(a)(3) of the Act, monitoring
shall be capable of demonstrating continuous compliance during the
applicable reporting period. Such monitoring data shall be of sufficient
quality to be used as a basis for enforcing all applicable requirements
established under this subpart, including emission limitations;
(iv) A statement requiring the owner or operator to comply with all
applicable requirements contained in subpart A of this part;
(3) All provisions contained in the Notice of MACT Approval shall be
federally enforceable upon the effective date of issuance of such
notice, as provided by paragraph (j) of this section.
(4) The Notice of MACT Approval shall expire if construction or
reconstruction has not commenced within 18 months of issuance, unless
the permitting authority has granted an extension which shall not exceed
an additional 12 months.
(h) Opportunity for public comment on the Notice of MACT Approval.
(1) The permitting authority will provide opportunity for public comment
on the Notice of MACT Approval, including, at a minimum:
(i) Availability for public inspection in at least one location in
the area affected of the information submitted by the owner or operator
and of the permitting authority's initial decision to approve the
application;
(ii) A 30-day period for submittal of public comment; and
(iii) A notice by prominent advertisement in the area affected of
the location of the source information and initial decision specified in
paragraph (h)(1)(i) of this section.
(2) At the discretion of the permitting authority, the Notice of
MACT Approval setting forth the initial decision to approve the
application may become final automatically at the end of
[[Page 91]]
the comment period if no adverse comments are received. If adverse
comments are received, the permitting authority shall have 30 days after
the end of the comment period to make any necessary revisions in its
analysis and decide whether to finally approve the application.
(i) EPA notification. The permitting authority shall send a copy of
the final Notice of MACT Approval, notice of approval of a title V
permit application incorporating a MACT determination (in those
instances where the owner or operator either is required or elects to
obtain such a permit before construction or reconstruction), or other
notice of approval issued pursuant to paragraph (c)(2)(ii) of this
section to the Administrator through the appropriate Regional Office,
and to all other State and local air pollution control agencies having
jurisdiction in affected States.
(j) Effective date. The effective date of a MACT determination shall
be the date the Notice of MACT Approval becomes final, the date of
issuance of a title V permit incorporating a MACT determination (in
those instances where the owner or operator either is required or elects
to obtain such a permit before construction or reconstruction), or the
date any other notice of approval issued pursuant to paragraph
(c)(2)(ii) of this section becomes final.
(k) Compliance date. On and after the date of start-up, a
constructed or reconstructed major source which is subject to the
requirements of this subpart shall be in compliance with all applicable
requirements specified in the MACT determination.
(l) Compliance with MACT determinations. (1) An owner or operator of
a constructed or reconstructed major source that is subject to a MACT
determination shall comply with all requirements in the final Notice of
MACT Approval, the title V permit (in those instances where the owner or
operator either is required or elects to obtain such a permit before
construction or reconstruction), or any other final notice of approval
issued pursuant to paragraph (c)(2)(ii) of this section, including but
not limited to any MACT emission limitation or MACT work practice
standard, and any notification, operation and maintenance, performance
testing, monitoring, reporting, and recordkeeping requirements.
(2) An owner or operator of a constructed or reconstructed major
source which has obtained a MACT determination shall be deemed to be in
compliance with section 112(g)(2)(B) of the Act only to the extent that
the constructed or reconstructed major source is in compliance with all
requirements set forth in the final Notice of MACT Approval, the title V
permit (in those instances where the owner or operator either is
required or elects to obtain such a permit before construction or
reconstruction), or any other final notice of approval issued pursuant
to paragraph (c)(2)(ii) of this section. Any violation of such
requirements by the owner or operator shall be deemed by the permitting
authority and by EPA to be a violation of the prohibition on
construction or reconstruction in section 112(g)(2)(B) for whatever
period the owner or operator is determined to be in violation of such
requirements, and shall subject the owner or operator to appropriate
enforcement action under the Act.
(m) Reporting to the Administrator. Within 60 days of the issuance
of a final Notice of MACT Approval, a title V permit incorporating a
MACT determination (in those instances where the owner or operator
either is required or elects to obtain such a permit before construction
or reconstruction), or any other final notice of approval issued
pursuant to paragraph (c)(2)(ii) of this section, the permitting
authority shall provide a copy of such notice to the Administrator, and
shall provide a summary in a compatible electronic format for inclusion
in the MACT data base.
[61 FR 68401, Dec. 27, 1996]
Sec. 63.44 Requirements for constructed or reconstructed major sources
subject to a subsequently promulgated MACT standard or MACT requirement.
(a) If the Administrator promulgates an emission standard under
section 112(d) or section 112(h) of the Act or the permitting authority
issues a determination under section 112(j) of the Act that is
applicable to a stationary source or group of sources which would
[[Page 92]]
be deemed to be a constructed or reconstructed major source under this
subpart before the date that the owner or operator has obtained a final
and legally effective MACT determination under any of the review options
available pursuant to Sec. 63.43, the owner or operator of the
source(s) shall comply with the promulgated standard or determination
rather than any MACT determination under section 112(g) by the
permitting authority, and the owner or operator shall comply with the
promulgated standard by the compliance date in the promulgated standard.
(b) If the Administrator promulgates an emission standard under
section 112(d) or section 112(h) of the Act or the permitting authority
makes a determination under section 112(j) of the Act that is applicable
to a stationary source or group of sources which was deemed to be a
constructed or reconstructed major source under this subpart and has
been subject to a prior case-by-case MACT determination pursuant to
Sec. 63.43, and the owner and operator obtained a final and legally
effective case-by-case MACT determination prior to the promulgation date
of such emission standard, then the permitting authority shall (if the
initial title V permit has not yet been issued) issue an initial
operating permit which incorporates the emission standard or
determination, or shall (if the initial title V permit has been issued)
revise the operating permit according to the reopening procedures in 40
CFR part 70 or part 71, whichever is relevant, to incorporate the
emission standard or determination.
(1) The EPA may include in the emission standard established under
section 112(d) or section 112(h) of the Act a specific compliance date
for those sources which have obtained a final and legally effective MACT
determination under this subpart and which have submitted the
information required by Sec. 63.43 to the EPA before the close of the
public comment period for the standard established under section 112(d)
of the Act. Such date shall assure that the owner or operator shall
comply with the promulgated standard as expeditiously as practicable,
but not longer than 8 years after such standard is promulgated. In that
event, the permitting authority shall incorporate the applicable
compliance date in the title V operating permit.
(2) If no compliance date has been established in the promulgated
112(d) or 112(h) standard or section 112(j) determination, for those
sources which have obtained a final and legally effective MACT
determination under this subpart, then the permitting authority shall
establish a compliance date in the permit that assures that the owner or
operator shall comply with the promulgated standard or determination as
expeditiously as practicable, but not longer than 8 years after such
standard is promulgated or a section 112(j) determination is made.
(c) Notwithstanding the requirements of paragraphs (a) and (b) of
this section, if the Administrator promulgates an emission standard
under section 112(d) or section 112(h) of the Act or the permitting
authority issues a determination under section 112(j) of the Act that is
applicable to a stationary source or group of sources which was deemed
to be a constructed or reconstructed major source under this subpart and
which is the subject of a prior case-by-case MACT determination pursuant
to Sec. 63.43, and the level of control required by the emission
standard issued under section 112(d) or section 112(h) or the
determination issued under section 112(j) is less stringent than the
level of control required by any emission limitation or standard in the
prior MACT determination, the permitting authority is not required to
incorporate any less stringent terms of the promulgated standard in the
title V operating permit applicable to such source(s) and may in its
discretion consider any more stringent provisions of the prior MACT
determination to be applicable legal requirements when issuing or
revising such an operating permit.
[61 FR 68404, Dec. 27, 1996]
Sec. Sec. 63.45-63.49 [Reserved]
Sec. 63.50 Applicability.
(a) General applicability. (1) The requirements of this section
through Sec. 63.56 implement section 112(j) of the Clean Air Act (as
amended in 1990). The requirements of this section through
[[Page 93]]
Sec. 63.56 apply in each State beginning on the effective date of an
approved title V permit program in such State. The requirements of this
section through Sec. 63.56 do not apply to research or laboratory
activities as defined in Sec. 63.51.
(2) The requirements of this section through Sec. 63.56 apply to:
(i) The owner or operator of affected sources within a source
category or subcategory under this part that are located at a major
source that is subject to an approved title V permit program and for
which the Administrator has failed to promulgate emission standards by
the section 112(j) deadlines. If title V applicability has been deferred
for a source category, then section 112(j) is not applicable for sources
in that category within that State, local or tribal jurisdiction until
those sources become subject to title V permitting requirements; and
(ii) Permitting authorities with an approved title V permit program.
(b) Relationship to State and local requirements. Nothing in
Sec. Sec. 63.50 through 63.56 shall prevent a State or local regulatory
agency from imposing more stringent requirements, as a matter of State
or local law, than those contained in Sec. Sec. 63.50 through 63.56.
(c) The procedures in Sec. Sec. 63.50 through 63.56 apply for each
affected source only after the section 112(j) deadline for the source
category or subcategory in question has passed, and only until such time
as a generally applicable Federal standard governing that source has
been promulgated under section 112(d) or 112(h) of the Act. Once a
generally applicable Federal standard governing that source has been
promulgated, the owner or operator of the affected source and the
permitting authority are not required to take any further actions to
develop an equivalent emission limitation under section 112(j) of the
Act.
(d) Any final equivalent emission limitation for an affected source
which is issued by the permitting authority pursuant to Sec. Sec. 63.50
through 63.56 prior to promulgation of a generally applicable Federal
standard governing that source under section 112(d) or 112(h) of the Act
shall be deemed an applicable Federal requirement adopted pursuant to
section 112(j) of the Act. Each such equivalent emission limitation
shall take effect upon issuance of the permit containing that limitation
under section 112(j)(5) of the Act, and shall remain applicable to the
source until such time as it may be revised or supplanted pursuant to
the procedures established by Sec. Sec. 63.50 through 63.56. Such a
final equivalent emission limitation, and all associated requirements
adopted pursuant to Sec. 63.52(f)(2), are directly enforceable under
Federal law regardless of whether or not any permit in which they may be
contained remains in effect.

Sec. 63.51 Definitions.
Terms used in Sec. Sec. 63.50 through 63.56 that are not defined in
this section have the meaning given to them in the Act, or in subpart A
of this part.
Affected source means the collection of equipment, activities, or
both within a single contiguous area and under common control that is in
a section 112(c) source category or subcategory for which the
Administrator has failed to promulgate an emission standard by the
section 112(j) deadline, and that is addressed by an applicable MACT
emission limitation established pursuant to this subpart.
Available information means, for purposes of conducting a MACT floor
finding and identifying control technology options under this subpart,
any information that is available as of the date on which the first Part
2 MACT application is filed for a source in the relevant source category
or subcategory in the State or jurisdiction; and, pursuant to the
requirements of this subpart, is additional relevant information that
can be expeditiously provided by the Administrator, is submitted by the
applicant or others prior to or during the public comment period on the
section 112(j) equivalent emission limitation for that source, or
information contained in the information sources in paragraphs (1)
through (5) of this definition.
(1) A relevant proposed regulation, including all supporting
information;
[[Page 94]]
(2) Relevant background information documents for a draft or
proposed regulation.
(3) Any relevant regulation, information or guidance collected by
the Administrator establishing a MACT floor finding and/or MACT
determination.
(4) Relevant data and information available from the Clean Air
Technology Center developed pursuant to section 112(l)(3) of the Act.
(5) Relevant data and information contained in the Aerometric
Information Retrieval System (AIRS).
(6) Any additional information that can be expeditiously provided by
the Administrator, and
(7) Any information provided by applicants in an application for a
permit, permit modification, administrative amendment, or Notice of MACT
Approval pursuant to the requirements of this subpart.
(8) Any additional relevant information provided by the applicant.
Control technology means measures, processes, methods, systems, or
techniques to limit the emission of hazardous air pollutants including,
but not limited to, measures which:
(1) Reduce the quantity, or eliminate emissions, of such pollutants
through process changes, substitution of materials or other
modifications;
(2) Enclose systems or processes to eliminate emissions;
(3) Collect, capture, or treat such pollutants when released from a
process, stack, storage or fugitive emissions point;
(4) Are design, equipment, work practice, or operational standards
(including requirements for operator training or certification) as
provided in 42 U.S.C. 7412(h); or
(5) Are a combination of paragraphs (1) through (4) of this
definition.
Enhanced review means a review process containing all administrative
steps needed to ensure that the terms and conditions resulting from the
review process can be incorporated using title V permitting procedures.
Equivalent emission limitation means an emission limitation,
established under section 112(j) of the Act, which is equivalent to the
MACT standard that EPA would have promulgated under section 112(d) or
(h) of the Act.
Maximum achievable control technology (MACT) emission limitation for
existing sources means the emission limitation reflecting the maximum
degree of reduction in emissions of hazardous air pollutants (including
a prohibition on such emissions, where achievable) that the
Administrator, taking into consideration the cost of achieving such
emission reductions, and any non-air quality health and environmental
impacts and energy requirements, determines is achievable by sources in
the category or subcategory to which such emission standard applies.
This limitation shall not be less stringent than the MACT floor.
Maximum achievable control technology (MACT) emission limitation for
new sources means the emission limitation which is not less stringent
than the emission limitation achieved in practice by the best controlled
similar source, and which reflects the maximum degree of reduction in
emissions of hazardous air pollutants (including a prohibition on such
emissions, where achievable) that the Administrator, taking into
consideration the cost of achieving such emission reduction, and any
non-air quality health and environmental impacts and energy
requirements, determines is achievable by sources in the category or
subcategory to which such emission standard applies.
Maximum Achievable Control Technology (MACT) floor means:
(1) For existing sources:
(i) The average emission limitation achieved by the best performing
12 percent of the existing sources in the United States (for which the
Administrator has emissions information), excluding those sources that
have, within 18 months before the emission standard is proposed or
within 30 months before such standard is promulgated, whichever is
later, first achieved a level of emission rate or emission reduction
which complies, or would comply if the source is not subject to such
standard, with the lowest achievable emission rate (as defined in
section 171 of the Act) applicable to the source category and prevailing
at the time, in the category or subcategory, for categories and
subcategories of stationary sources with 30 or more sources; or
[[Page 95]]
(ii) The average emission limitation achieved by the best performing
five sources (for which the Administrator has or could reasonably obtain
emissions information) in the category or subcategory, for categories or
subcategories with fewer than 30 sources;
(2) For new sources, the emission limitation achieved in practice by
the best controlled similar source.
New affected source means the collection of equipment, activities,
or both, that if constructed after the issuance of a section 112(j)
permit for the source pursuant to Sec. 63.52, is subject to the
applicable MACT emission limitation for new sources. Each permit must
define the term ``new affected source,'' which will be the same as the
``affected source'' unless a different collection is warranted based on
consideration of factors including:
(1) Emission reduction impacts of controlling individual sources
versus groups of sources;
(2) Cost effectiveness of controlling individual equipment;
(3) Flexibility to accommodate common control strategies;
(4) Cost/benefits of emissions averaging;
(5) Incentives for pollution prevention;
(6) Feasibility and cost of controlling processes that share common
equipment (e.g., product recovery devices);
(7) Feasibility and cost of monitoring; and
(8) Other relevant factors.
Permitting authority means the permitting authority as defined in
part 70 of this chapter.
Research or laboratory activities means activities whose primary
purpose is to conduct research and development into new processes and
products where such activities are operated under the close supervision
of technically trained personnel and are not engaged in the manufacture
of products for commercial sale in commerce, except in a de minimis
manner; and where the source is not in a source category, specifically
addressing research or laboratory activities, that is listed pursuant to
section 112(c)(7) of the Act.
Section 112(j) deadline means the date 18 months after the date for
which a relevant standard is scheduled to be promulgated under this
part, except that for all major sources listed in the source category
schedule for which a relevant standard is scheduled to be promulgated by
November 15, 1994, the section 112(j) deadline is November 15, 1996, and
for all major sources listed in the source category schedule for which a
relevant standard is scheduled to be promulgated by November 15, 1997,
the section 112(j) deadline is December 15, 1999.
Similar source means that equipment or collection of equipment that,
by virtue of its structure, operability, type of emissions and volume
and concentration of emissions, is substantially equivalent to the new
affected source and employs control technology for control of emissions
of hazardous air pollutants that is practical for use on the new
affected source.
Source category schedule for standards means the schedule for
promulgating MACT standards issued pursuant to section 112(e) of the
Act.
[59 FR 26449, May 20, 1994, as amended at 61 FR 21372, May 10, 1996; 64
FR 26314, May 14, 1999; 67 FR 16605, Apr. 5, 2002]
Sec. 63.52 Approval process for new and existing affected sources.
(a) Sources subject to section 112(j) as of the section 112(j)
deadline. The requirements of paragraphs (a)(1) and (2) of this section
apply to major sources that include, as of the section 112(j) deadline,
one or more sources in a category or subcategory for which the
Administrator has failed to promulgate an emission standard under this
part on or before an applicable section 112(j) deadline. Existing source
MACT requirements (including relevant compliance deadlines), as
specified in a title V permit issued to the source pursuant to the
requirements of the subpart, must apply to such sources.
(1) The owner or operator must submit an application for a title V
permit or for a revision to an existing title V permit or a pending
title V permit meeting the requirements of Sec. 63.53(a) by the section
112(j) deadline if the owner or operator can reasonably determine that
one or more sources at the major source belong in the category or
subcategory subject to section 112(j).
[[Page 96]]
(2) If an application was not submitted under paragraph (a)(1) of
this section and if notified by the permitting authority, the owner or
operator must submit an application for a title V permit or for a
revision to an existing title V permit or a pending title V permit
meeting the requirements of Sec. 63.53(a) within 30 days after being
notified in writing by the permitting authority that one or more sources
at the major source belong to such category or subcategory. Permitting
authorities are not required to make such notification.
(3) The requirements in paragraphs (a)(3)(i) through (ii) of this
section apply when the owner or operator has obtained a title V permit
that incorporates a case-by-case MACT determination by the permitting
authority under section 112(g) or has submitted a title V permit
application for a revision that incorporates a case-by-case MACT
determination under section 112(g), but has not submitted an application
for a title V permit revision that addresses the emission limitation
requirements of section 112(j).
(i) When the owner or operator has a title V permit that
incorporates a case-by-case MACT determination by the permitting
authority under section 112(g), the owner or operator must submit an
application meeting the requirements of Sec. 63.53(a) for a title V
permit revision within 30 days of the section 112(j) deadline or within
30 days of being notified in writing by the permitting authority that
one or more sources at the major source belong in such category or
subcategory. Using the procedures established in paragraph (e) of this
section, the permitting authority must determine whether the emission
limitations adopted pursuant to the prior case-by-case MACT
determination under section 112(g) are substantially as effective as the
emission limitations which the permitting authority would otherwise
adopt pursuant to section 112(j) for the source in question. If the
permitting authority determines that the emission limitations previously
adopted to effectuate section 112(g) are substantially as effective as
the emission limitations which the permitting authority would otherwise
adopt to effectuate section 112(j) for the source, then the permitting
authority must retain the existing emission limitations in the permit as
the emission limitations to effectuate section 112(j). The title V
permit applicable to that source must be revised accordingly. If the
permitting authority does not retain the existing emission limitations
in the permit as the emission limitations to effectuate section 112(j),
the MACT requirements of this subpart are satisfied upon issuance of a
revised title V permit incorporating any additional section 112(j)
requirements.
(ii) When the owner or operator has submitted a title V permit
application that incorporates a case-by-case MACT determination by the
permitting authority under section 112(g), but has not received the
permit incorporating the section 112(g) requirements, the owner or
operator must continue to pursue a title V permit that addresses the
emission limitation requirements of section 112(g). Within 30 days of
issuance of that title V permit, the owner or operator must submit an
application meeting the requirements of Sec. 63.53(a) for a change to
the existing title V permit. Using the procedures established in
paragraph (e) of this section, the permitting authority must determine
whether the emission limitations adopted pursuant to the prior case-by-
case MACT determination under section 112(g) are substantially as
effective as the emission limitations which the permitting authority
would otherwise adopt pursuant to section 112(j) for the source in
question. If the permitting authority determines that the emission
limitations previously adopted to effectuate section 112(g) are
substantially as effective as the emission limitations which the
permitting authority would otherwise adopt to effectuate section 112(j)
for the source, then the permitting authority must retain the existing
emission limitations in the permit as the emission limitations to
effectuate section 112(j). The title V permit applicable to that source
must be revised accordingly. If the permitting authority does not retain
the existing emission limitations in the permit as the emission
limitations to effectuate section 112(j), the MACT requirements of this
subpart are satisfied
[[Page 97]]
upon issuance of a revised title V permit incorporating any additional
section 112(j) requirements.
(b) Sources that become subject to section 112(j) after the section
112(j) deadline and that do not have a title V permit addressing section
112(j) requirements. The requirements of paragraphs (b)(1) through (4)
of this section apply to sources that do not meet the criteria in
paragraph (a) of this section on the section 112(j) deadline and are,
therefore, not subject to section 112(j) on that date, but where events
occur subsequent to the section 112(j) deadline that would bring the
source under the requirements of this subpart, and the source does not
have a title V permit that addresses the requirements of section 112(j).
(1) When one or more sources in a category or subcategory subject to
the requirements of this subpart are installed at a major source, or
result in the source becoming a major source due to the installation,
and the installation does not invoke section 112(g) requirements, the
owner or operator must submit an application meeting the requirements of
Sec. 63.53(a) within 30 days of startup of the source. This application
shall be reviewed using the procedures established in paragraph (e) of
this section. Existing source MACT requirements (including relevant
compliance deadlines), as specified in a title V permit issued pursuant
to the requirements of this subpart, shall apply to such sources.
(2) The requirements in this paragraph apply when one or more
sources in a category or subcategory subject to this subpart are
installed at a major source, or result in the source becoming a major
source due to the installation, and the installation does require
emission limitations to be established and permitted under section
112(g), and the owner or operator has not submitted an application for a
title V permit revision that addresses the emission limitation
requirements of section 112(j). In this case, the owner or operator must
apply for and obtain a title V permit that addresses the emission
limitation requirements of section 112(g). Within 30 days of issuance of
that title V permit, the owner or operator must submit an application
meeting the requirements of Sec. 63.53(a) for a revision to the
existing title V permit. Using the procedures established in paragraph
(e) of this section, the permitting authority must determine whether the
emission limitations adopted pursuant to the prior case-by-case MACT
determination under section 112(g) are substantially as effective as the
emission limitations which the permitting authority would otherwise
adopt pursuant to section 112(j) for the source in question. If the
permitting authority determines that the emission limitations previously
adopted to effectuate section 112(g) are substantially as effective as
the emission limitations which the permitting authority would otherwise
adopt to effectuate section 112(j) for the source, then the permitting
authority must retain the existing emission limitations in the permit as
the emission limitations to effectuate section 112(j). The title V
permit applicable to that source must be revised accordingly. If the
permitting authority does not retain the existing emission limitations
in the permit as the emission limitations to effectuate section 112(j),
the MACT requirements of this subpart are satisfied upon issuance of a
revised title V permit incorporating any additional section 112(j)
requirements.
(3) The owner or operator of an area source that, due to a
relaxation in any federally enforceable emission limitation (such as a
restriction on hours of operation), increases its potential to emit
hazardous air pollutants such that the source becomes a major source
that is subject to this subpart, must submit an application meeting the
requirements of Sec. 63.53(a) for a title V permit or for an
application for a title V permit revision within 30 days after the date
that such source becomes a major source. This application must be
reviewed using the procedures established in paragraph (e) of this
section. Existing source MACT requirements (including relevant
compliance deadlines), as specified in a title V permit issued pursuant
to the requirements of this subpart, must apply to such sources.
(4) On or after April 5, 2002, if the Administrator establishes a
lesser quantity emission rate under section
[[Page 98]]
112(a)(1) of the Act that results in an area source becoming a major
source that is subject to this subpart, then the owner or operator of
such a major source must submit an application meeting the requirements
of Sec. 63.53(a) for a title V permit or for a change to an existing
title V permit or pending title V permit on or before the date 6 months
after the date that such source becomes a major source. Existing source
MACT requirements (including relevant compliance deadlines), as
specified in a title V permit issued pursuant to the requirements of
this subpart, shall apply to such sources.
(c) Sources that have a title V permit addressing section 112(j)
requirements. The requirements of paragraphs (c)(1) and (2) of this
section apply to major sources that include one or more sources in a
category or subcategory for which the Administrator fails to promulgate
an emission standard under this part on or before an applicable section
112(j) deadline, and the owner or operator has a permit meeting the
section 112(j) requirements, and where changes occur at the major source
to equipment, activities, or both, subsequent to the section 112(j)
deadline.
(1) If the title V permit already provides the appropriate
requirements that address the events that occur under paragraph (c) of
this section subsequent to the section 112(j) deadline, then the source
must comply with the applicable new source MACT or existing source MACT
requirements as specified in the permit, and the section 112(j)
requirements are thus satisfied.
(2) If the title V permit does not contain the appropriate
requirements that address the events that occur under paragraph (c) of
this section subsequent to the section 112(j) deadline, then the owner
or operator must submit an application for a revision to the existing
title V permit that meets the requirements of Sec. 63.53(a). The
application must be submitted within 30 days of beginning construction
and must be reviewed using the procedures established in paragraph (e)
of this section. Existing source MACT requirements (including relevant
compliance deadlines), as specified in a title V permit issued pursuant
to the requirements of this subpart, shall apply to such sources.
(d) Requests for applicability determination or notice of MACT
approval. (1) An owner or operator who is unsure of whether one or more
sources at a major source belong in a category or subcategory for which
the Administrator has failed to promulgate an emission standard under
this part may, on or before an applicable section 112(j) deadline,
request an applicability determination from the permitting authority by
submitting an application meeting the requirements of Sec. 63.53(a) by
the applicable deadlines specified in paragraphs (a), (b), or (c) of
this section.
(2) In addition to meeting the requirements of paragraphs (a), (b),
and (c) of this section, the owner or operator of a new affected source
may submit an application for a Notice of MACT Approval before
construction, pursuant to Sec. 63.54.
(e) Permit application review. (1) Each owner or operator who is
required to submit to the permitting authority a Part 1 MACT application
which meets the requirements of Sec. 63.53(a) for one or more sources
in a category or subcategory subject to section 112(j) must also submit
to the permitting authority a timely Part 2 MACT application for the
same sources which meets the requirements of Sec. 63.53(b). Each owner
or operator shall submit the Part 2 MACT application for the sources in
a particular category or subcategory no later than the applicable date
specified in table 1 to this subpart. The submission date specified in
table 1 to this subpart for Miscellaneous Organic Chemical Manufacturing
shall apply to sources in each of the source categories listed in table
2 to this subpart. When the owner or operator is required by Sec. Sec.
63.50 through 63.56 to submit an application meeting the requirements of
Sec. 63.53(a) by a date which is after the date for a Part 2 MACT
application for sources in the category or subcategory in question
established by table 1 to this subpart, the owner or operator shall
submit a Part 2 MACT application meeting the requirements of Sec.
63.53(b) within 60 additional days after the applicable deadline for
submission of the Part 1 MACT application. Part 2
[[Page 99]]
MACT applications must be reviewed by the permitting authority according
to procedures established in Sec. 63.55. The resulting MACT
determination must be incorporated into the source's title V permit
according to procedures established under title V, and any other
regulations approved under title V in the jurisdiction in which the
affected source is located.
(2) Notwithstanding paragraph (e)(1) of this section, the owner or
operator may request either an applicability determination or an
equivalency determination by the permitting authority as provided in
paragraphs (e)(2)(i) and (ii) of this section.
(i) Each owner or operator who submitted a request for an
applicability determination pursuant to paragraph (d)(1) of this section
on or before May 15, 2002, which remains pending before the permitting
authority on May 30, 2003, and who still wishes to obtain such a
determination, must resubmit that request by July 29, 2003, or by the
date which is 60 days after the Administrator publishes in the Federal
Register a proposed standard under section 112(d) or 112(h) of the Act
for the category or subcategory in question, whichever is later. Each
request for an applicability determination which is resubmitted under
this paragraph (e)(2)(i) must be supplemented to discuss the relation
between the source(s) in question and the applicability provision in the
proposed standard for the category or subcategory in question, and to
explain why there may still be uncertainties that require a
determination of applicability. The permitting authority must take
action upon each properly resubmitted and supplemented request for an
applicability determination within an additional 60 days after the
applicable deadline for the resubmitted request. If the applicability
determination is positive, the owner or operator must submit a Part 2
MACT application meeting the requirements of Sec. 63.53(b) by the date
specified for the category or subcategory in question in Table 1 to this
subpart. If the applicability determination is negative, then no further
action by the owner or operator is necessary.
(ii) As specified in paragraphs (a) and (b) of this section, an
owner or operator who has submitted an application meeting the
requirements of Sec. 63.53(a) may request a determination by the
permitting authority of whether emission limitations adopted pursuant to
a prior case-by-case MACT determination under section 112(g) that apply
to one or more sources at a major source in a relevant category or
subcategory are substantially as effective as the emission limitations
which the permitting authority would otherwise adopt pursuant to section
112(j) for the source in question. Such a request must be submitted by
the date for the category or subcategory in question specified in Table
1 to this subpart. Any owner or operator who previously submitted such a
request under a prior version of this paragraph (e)(2)(ii) need not
resubmit the request. Each request for an equivalency determination
under this paragraph (e)(2)(ii), regardless of when it was submitted,
will be construed in the alternative as a complete application for an
equivalent emission limitation under section 112(j). The process for
determination by the permitting authority of whether the emission
limitations in the prior case-by-case MACT determination are
substantially as effective as the emission limitations which the
permitting authority would otherwise adopt under section 112(j) must
include the opportunity for full public, EPA, and affected State review
prior to a final determination. If the permitting authority determines
that the emission limitations in the prior case-by-case MACT
determination are substantially as effective as the emission limitations
which the permitting authority would otherwise adopt under section
112(j), then the permitting authority must adopt the existing emission
limitations in the permit as the emission limitations to effectuate
section 112(j) for the source in question. If more than 3 years remain
on the current title V permit, the owner or operator must submit an
application for a title V permit revision to make any conforming changes
in the permit required to adopt the existing emission limitations as the
section 112(j) MACT emission limitations. If less than 3 years remain on
the current title V permit, any required conforming changes must be made
when the permit
[[Page 100]]
is renewed. If the permitting authority determines that the emission
limitations in the prior case-by-case MACT determination under section
112(g) are not substantially as effective as the emission limitations
which the permitting authority would otherwise adopt for the source in
question under section 112(j), the permitting authority must make a new
MACT determination and adopt a title V permit incorporating an
appropriate equivalent emission limitation under section 112(j). Such a
determination constitutes final action for purposes of judicial review
under 40 CFR 70.4(b)(3)(x) and corresponding State title V program
provisions.
(3) Within 60 days of submittal of the Part 2 MACT application, the
permitting authority must notify the owner or operator in writing
whether the application is complete or incomplete. The Part 2 MACT
application shall be deemed complete on the date it was submitted unless
the permitting authority notifies the owner or operator in writing
within 60 days of the submittal that the Part 2 MACT application is
incomplete. A Part 2 MACT application is complete if it is sufficient to
begin processing the application for a title V permit addressing section
112(j) requirements. In the event that the permitting authority
disapproves a permit application or determines that the application is
incomplete, the owner or operator must revise and resubmit the
application to meet the objections of the permitting authority. The
permitting authority must specify a reasonable period in which the owner
or operator is required to remedy the deficiencies in the disapproved or
incomplete application. This period may not exceed 6 months from the
date the owner or operator is first notified that the application has
been disapproved or is incomplete.
(4) Following submittal of a Part 1 or Part 2 MACT application, the
permitting authority may request additional information from the owner
or operator. The owner or operator must respond to such requests in a
timely manner.
(5) If the owner or operator has submitted a timely and complete
application as required by this section, any failure to have a title V
permit addressing section 112(j) requirements shall not be a violation
of section 112(j), unless the delay in final action is due to the
failure of the applicant to submit, in a timely manner, information
required or requested to process the application. Once a complete
application is submitted, the owner or operator shall not be in
violation of the requirement to have a title V permit addressing section
112(j) requirements.
(f) Permit content. The title V permit must contain an equivalent
emission limitation (or limitations) for the relevant category or
subcategory determined on a case-by-case basis by the permitting
authority, or, if the applicable criteria in subpart D of this part are
met, the title V permit may contain an alternative emission limitation.
For the purposes of the preceding sentence, early reductions made
pursuant to section 112(i)(5)(A) of the Act must be achieved not later
than the date on which the relevant standard should have been
promulgated according to the source category schedule for standards.
(1) The title V permit must contain an emission standard or emission
limitation that is equivalent to existing source MACT and an emission
standard or emission limitation that is equivalent to new source MACT
for control of emissions of hazardous air pollutants. The MACT emission
standards or limitations must be determined by the permitting authority
and must be based on the degree of emission reductions that can be
achieved if the control technologies or work practices are installed,
maintained, and operated properly. The permit must also specify the
affected source and the new affected source. If construction of a new
affected source or reconstruction of an affected source commences after
a title V permit meeting the requirements of section 112(j) has been
issued for the source, the new source MACT compliance dates must apply.
(2) The title V permit must specify any notification, operation and
maintenance, performance testing, monitoring, and reporting and
recordkeeping requirements. In developing the title V permit, the
permitting authority must consider and specify the
[[Page 101]]
appropriate provisions of subpart A of this part. The title V permit
must also include the information in paragraphs (f)(2)(i) through (iii)
of this section.
(i) In addition to the MACT emission limitation required by
paragraph (f)(1) of this section, additional emission limits, production
limits, operational limits or other terms and conditions necessary to
ensure practicable enforceability of the MACT emission limitation.
(ii) Compliance certifications, testing, monitoring, reporting and
recordkeeping requirements that are consistent with requirements
established pursuant to title V and paragraph (h) of this section.
(iii) Compliance dates by which the owner or operator must be in

terms and conditions of the permit.
(A) The owner or operator of an affected source subject to the
requirements of this subpart must comply with the emission limitation(s)
by the date established in the source's title V permit. In no case shall
such compliance date be later than 3 years after the issuance of the
permit for that source, except where the permitting authority issues a
permit that grants an additional year to comply in accordance with
section 112(i)(3)(B) of the Act, or unless otherwise specified in
section 112(i), or in subpart D of this part.
(B) The owner or operator of a new affected source, as defined in
the title V permit meeting the requirements of section 112(j), that is
subject to the requirements of this subpart must comply with a new
source MACT level of control immediately upon startup of the new
affected source.
(g) Permit issuance dates. The permitting authority must issue a
title V permit meeting section 112(j) requirements within 18 months
after submittal of the complete Part 2 MACT application.
(h) Enhanced monitoring. In accordance with section 114(a)(3) of the
Act, monitoring shall be capable of demonstrating continuous compliance
for each compliance period during the applicable reporting period. Such
monitoring data shall be of sufficient quality to be used as a basis for
directly enforcing all applicable requirements established under this
subpart, including emission limitations.
(i) MACT emission limitations. (1) The owner or operator of affected
sources subject to paragraphs (a), (b), and (c) of this section must
comply with all requirements of this subpart that are applicable to

112(g) MACT determination has been made.
(b) Part 2 MACT application. (1) In compiling a Part 2 MACT
application, the owner or operator may cross-reference specific
information in any prior submission by the owner or operator to the
permitting authority, but in cross-referencing such information the
owner or operator may not presume favorable action on any prior
application or request which is still pending. In compiling a Part 2
MACT application, the owner or operator may also cross-reference any
part of a standard proposed by the Administrator pursuant to section
112(d) or 112(h) of the Act for any category or subcategory which
[[Page 102]]
includes sources to which the Part 2 application applies.
(2) The Part 2 application for a MACT determination must contain the
information in paragraphs (b)(2)(i) through (b)(2)(v) of this section.
(i) For a new affected source, the anticipated date of startup of
operation.
(ii) Each emission point or group of emission points at the affected
source which is part of a category or subcategory for which a Part 2
MACT application is required, and each of the hazardous air pollutants
emitted at those emission points. When the Administrator has proposed a
standard pursuant to section 112(d) or 112(h) of the Act for a category
or subcategory, such information may be limited to those emission points
and hazardous air pollutants which would be subject to control under the
proposed standard.
(iii) Any existing Federal, State, or local limitations or
requirements governing emissions of hazardous air pollutants from those
emission points which are part of a category or subcategory for which a

required to, contain the following information:
(i) Recommended emission limitations for the affected source and
support information consistent with Sec. 63.52(f). The owner or
operator may recommend a specific design, equipment, work practice, or
operational standard, or combination thereof, as an emission limitation.
(ii) A description of the control technologies that would be applied
to meet the emission limitation including technical information on the
design, operation, size, estimated control efficiency and any other
information deemed appropriate by the permitting authority, and
identification of the affected sources to which the control technologies
must be applied.
(iii) Relevant parameters to be monitored and frequency of

Sec. 63.54 Preconstruction review procedures for new affected sources.
The requirements of this section apply to an owner or operator who
constructs a new affected source subject to Sec. 63.52(c)(1). The
purpose of this section is to describe alternative review processes that
the permitting authority may use to make a MACT determination for the
new affected source.
(a) Review process for new affected sources. (1) If the permitting
authority requires an owner or operator to obtain or revise a title V
permit before construction of the new affected source, or when the owner
or operator chooses to obtain or revise a title V permit before
construction, the owner or operator must follow the procedures
established under the applicable title V permit program before
construction of the new affected source.
(2) If an owner or operator is not required to obtain or revise a
title V permit before construction of the new affected source (and has
not elected to do so), but the new affected source is covered by any
preconstruction or preoperation review requirements established pursuant
to section 112(g) of the Act, then the owner or operator must comply
with those requirements in order to ensure that the requirements of
section 112(j) and (g) are satisfied. If the new affected source is not
covered by section 112(g), the permitting authority, in its discretion,
may issue a Notice of MACT Approval, or the equivalent, in accordance
with the procedures set forth in paragraphs (b) through (f) of this
section, or an equivalent permit review process, before construction or
operation of the new affected source.
(3) Regardless of the review process, the MACT determination shall
be consistent with the principles established in Sec. 63.55. The
application for a Notice of MACT Approval or a title V permit, permit
modification, or administrative amendment, whichever is applicable,
shall include the documentation required by Sec. 63.53.
[[Page 103]]
(b) Optional administrative procedures for preconstruction or
preoperation review for new affected sources. The permitting authority
may provide for an enhanced review of section 112(j) MACT determinations
for review procedures and compliance requirements equivalent to those
set forth in paragraphs (b) through (f) of this section.
(1) The permitting authority will notify the owner or operator in
writing as to whether the application for a MACT determination is
complete or whether additional information is required.
(2) The permitting authority will approve an applicant's proposed
control technology, or the permitting authority will notify the owner or
operator in writing of its intention to disapprove a control technology.
(3) The owner or operator may present in writing, within a time
frame specified by the permitting authority, additional information,
considerations, or amendments to the application before the permitting
authority's issuance of a final disapproval.
(4) The permitting authority will issue a preliminary approval or
issue a disapproval of the application, taking into account additional
information received from the owner or operator.
(5) A determination to disapprove any application will be in writing
and will specify the grounds on which the disapproval is based.
(6) Approval of an applicant's proposed control technology must be
set forth in a Notice of MACT Approval (or the equivalent) as described
in Sec. 63.52(f).
(c) Opportunity for public comment on Notice of MACT Approval. The
permitting authority will provide opportunity for public comment on the
preliminary Notice of MACT Approval prior to issuance, including, at a
minimum,
(1) Availability for public inspection in at least one location in
the area affected of the information submitted by the owner or operator
and of the permitting authority's tentative determination;
(2) A period for submittal of public comment of at least 30 days;
and
(3) A notice by prominent advertisement in the area affected of the
location of the source information and analysis specified in Sec.
63.52(f). The form and content of the notice must be substantially
equivalent to that found in Sec. 70.7 of this chapter.
(4) An opportunity for a public hearing, if one is requested. The
permitting authority will give at least 30 days notice in advance of any
hearing.
(d) Review by the EPA and affected States. The permitting authority
must send copies of the preliminary notice (in time for comment) and
final notice required by paragraph (c) of this section to the
Administrator through the appropriate Regional Office, and to all other
State and local air pollution control agencies having jurisdiction in
affected States. The permitting authority must provide EPA with a review
period for the final notice of at least 45 days and shall not issue a
final Notice of MACT Approval until EPA objections are satisfied.
(e) Compliance with MACT determinations. An owner or operator of a
major source that is subject to a MACT determination must comply with
notification, operation and maintenance, performance testing,
monitoring, reporting, and recordkeeping requirements established under
Sec. 63.52(h), under title V, and at the discretion of the permitting
authority, under subpart A of this part. The permitting authority must
provide the EPA with the opportunity to review compliance requirements
for consistency with requirements established pursuant to title V during
the review period under paragraph (d) of this section.
(f) Equivalency under section 112(l). If a permitting authority
requires preconstruction review for new source MACT determinations under
this subpart, such requirement shall not necessitate a determination
under subpart E of this part.
[59 FR 26449, May 20, 1994, as amended at 67 FR 16610, Apr. 5, 2002]
Sec. 63.55 Maximum achievable control technology (MACT) determinations
for affected sources subject to case-by-case determination
of equivalent emission limitations.
(a) Requirements for permitting authorities. The permitting
authority must determine whether the Sec. 63.53(a) Part 1 and Sec.
63.53(b) Part 2 MACT application is complete or an application for a
Notice of MACT Approval is approvable.
[[Page 104]]
In either case, when the application is complete or approvable, the
permitting authority must establish hazardous air pollutant emissions
limitations equivalent to the limitations that would apply if an
emission standard had been issued in a timely manner under section
112(d) or (h) of the Act. The permitting authority must establish these
emissions limitations consistent with the following requirements and
principles:
(1) Emission limitations must be established for the equipment and
activities within the affected sources within a source category or
subcategory for which the section 112(j) deadline has passed.
(2) Each emission limitation for an existing affected source must
reflect the maximum degree of reduction in emissions of hazardous air
pollutants (including a prohibition on such emissions, where achievable)
that the permitting authority, taking into consideration the cost of
achieving such emission reduction and any non-air quality health and
environmental impacts and energy requirements, determines is achievable
by affected sources in the category or subcategory for which the section
112(j) deadline has passed. This limitation must not be less stringent
than the MACT floor which must be established by the permitting
authority according to the requirements of section 112(d)(3)(A) and (B)
and must be based upon available information.
(3) Each emission limitation for a new affected source must reflect
the maximum degree of reduction in emissions of hazardous air pollutants
(including a prohibition on such emissions, where achievable) that the
permitting authority, taking into consideration the cost of achieving
such emission reduction and any non-air quality health and environmental
impacts and energy requirements, determines is achievable. This
limitation must not be less stringent than the emission limitation
achieved in practice by the best controlled similar source which must be
established by the permitting authority according to the requirements of
section 112(d)(3). This limitation must be based upon available
information.
(4) The permitting authority must select a specific design,
equipment, work practice, or operational standard, or combination
thereof, when it is not feasible to prescribe or enforce an equivalent
emission limitation due to the nature of the process or pollutant. It is
not feasible to prescribe or enforce a limitation when the Administrator
determines that hazardous air pollutants cannot be emitted through a
conveyance designed and constructed to capture such pollutant, or that
any requirement for, or use of, such a conveyance would be inconsistent
with any Federal, State, or local law, or the application of measurement
methodology to a particular class of sources is not practicable due to
technological and economic limitations.
(5) Nothing in this subpart shall prevent a State or local
permitting authority from establishing an emission limitation more
stringent than required by Federal regulations.
(b) Reporting to EPA. The owner or operator must submit additional
copies of its Part 1 and Part 2 MACT application for a title V permit,
permit revision, or Notice of MACT Approval, whichever is applicable, to
the EPA at the same time the material is submitted to the permitting
authority.
[67 FR 16610, Apr. 5, 2002]
Sec. 63.56 Requirements for case-by-case determination of equivalent
emission limitations after promulgation of subsequent MACT standard.
(a) If the Administrator promulgates a relevant emission standard
that is applicable to one or more affected sources within a major source
before the date a permit application under this paragraph (a) is
approved, the title V permit must contain the promulgated standard
rather than the emission limitation determined under Sec. 63.52, and
the owner or operator must comply with the promulgated standard by the
compliance date in the promulgated standard.
(b) If the Administrator promulgates a relevant emission standard
under section 112(d) or (h) of the Act that is applicable to a source
after the date a permit is issued pursuant to Sec. 63.52 or Sec.
63.54, the permitting authority must incorporate requirements of that
[[Page 105]]
standard in the title V permit upon its next renewal. The permitting
authority must establish a compliance date in the revised permit that
assures that the owner or operator must comply with the promulgated
standard within a reasonable time, but not longer than 8 years after
such standard is promulgated or 8 years after the date by which the
owner or operator was first required to comply with the emission
limitation established by the permit, whichever is earlier. However, in
no event shall the period for compliance for existing sources be shorter
than that provided for existing sources in the promulgated standard.
(c) Notwithstanding the requirements of paragraph (a) or (b) of this
section, the requirements of paragraphs (c)(1) and (2) of this section
shall apply.
(1) If the Administrator promulgates an emission standard under
section 112(d) or (h) that is applicable to an affected source after the
date a permit application under this paragraph is approved under Sec.
63.52 or Sec. 63.54, the permitting authority is not required to change
the emission limitation in the permit to reflect the promulgated
standard if the permitting authority determines that the level of
control required by the emission limitation in the permit is
substantially as effective as that required by the promulgated standard
pursuant to Sec. 63.1(e).
(2) If the Administrator promulgates an emission standard under
section 112(d) or (h) of the Act that is applicable to an affected
source after the date a permit application is approved under Sec. 63.52
or Sec. 63.54, and the level of control required by the promulgated
standard is less stringent than the level of control required by any
emission limitation in the prior MACT determination, the permitting
authority is not required to incorporate any less stringent emission
limitation of the promulgated standard in the title V permit and may in
its discretion consider any more stringent provisions of the MACT
determination to be applicable legal requirements when issuing or
revising such a title V permit.

Sec. 63.70 Applicability.
The provisions of this subpart apply to an owner or operator of an
existing source who wishes to obtain a compliance extension from a
standard issued under section 112(d) of the Act. The provisions of this
subpart also apply to a State or local agency acting pursuant to a
permit program approved under title V of the Act. The Administrator will
carry out the provisions of this subpart for any State that does not
have an approved permit program.
Sec. 63.71 Definitions.
All terms used in this subpart not defined in this section are given
the same meaning as in the Act.
Act means the Clean Air Act as amended.
Actual emissions means the actual rate of emissions of a pollutant,
but does not include excess emissions from a malfunction, or startups
and shutdowns associated with a malfunction. Actual emissions shall be
calculated using the source's actual operating rates, and types of
materials processed, stored, or combusted during the selected time
period.
Artificially or substantially greater emissions means abnormally
high emissions such as could be caused by equipment malfunctions,
accidents, unusually high production or operating rates compared to
historical rates, or other unusual circumstances.

equipment or process equipment or of a process to operate in a normal or
usual manner. Failures that are caused entirely or in part by poor
maintenance, careless operation, or any other preventable upset
condition or preventable equipment breakdown shall not be considered
malfunctions.
Not feasible to prescribe or enforce a numerical emission limitation
means a situation in which the Administrator or a State determines that
a pollutant (or stream of pollutants) listed pursuant to section 112(b)
of the Act cannot be emitted through a conveyance designed and
constructed to emit or capture such pollutant, or that any requirement
for, or use of, such a conveyance would be inconsistent with any Federal
law; or the application of measurement technology to a particular source
is not practicable due to technological or economic limitations.
Permitting authority means either a State agency with an approved
permitting program under Title V of the Act or the Administrator in
cases where the State does not have an approved permitting program.
Post-reduction year means the one year period beginning with the
date early reductions have to be achieved to qualify for a compliance
extension under subpart D of this part, unless a source has established
with the permitting authority an earlier one year period as the post-
reduction year. For most sources, the post-reduction year would begin
with the date of proposal of the first section 112(d) standard
applicable to the early reductions source; however, for sources that
have made enforceable commitments, it would be the year from January 1,
1994, through December 31, 1994.

Sec. 63.72 General provisions for compliance extensions.
(a) Except as provided in paragraph (f) of this section, a
permitting authority acting pursuant to a permitting program approved
under Title V of the Act shall by permit allow an existing source to
meet an alternative emission limitation in lieu of an emission
limitation promulgated under section 112(d) of the Act for a period of 6
years from the compliance date of the otherwise applicable standard
provided the source owner or operator demonstrates:
(1) According to the requirements of Sec. 63.74 that the source has
achieved a reduction of 90 percent (95 percent or more in the case of
hazardous air pollutants which are particulates) in emissions of:
(i) Total hazardous air pollutants from the source;
(ii) Total hazardous air pollutants from the source as adjusted for
high-risk pollutant weighting factors, if applicable.
(2) That such reduction was achieved before proposal of an
applicable standard or, for sources eligible to qualify for an
alternative emission limitation as specified in paragraph (c) of this
section, before January 1, 1994.
(b) A source granted an alternative emission limitation shall comply
with an applicable standard issued under section 112(d) of the Act
immediately upon expiration of the six year compliance extension period
specified in paragraph (a) of this section.
(c) An existing source that achieves the reduction specified in
paragraph (a)(1) of this section after proposal of an applicable section
112(d) standard but before January 1, 1994, may qualify for an
alternative emission limitation under paragraph (a) of this section if
the source makes an enforceable commitment, prior to proposal of the
applicable standard, to achieve such reduction. The enforceable
commitment shall be made according to the procedures and requirements of
Sec. 63.75.
(d) For each permit issued to a source under paragraph (a) of this
section, there shall be established as part of the permit an enforceable
alternative emission limitation for hazardous air pollutants reflecting
the reduction which qualified the source for the alternative emission
limitation.
(e) An alternative emission limitation shall not be available with
respect to standards or requirements promulgated to provide an ample
margin of safety to protect public health pursuant to section 112(f) of
the Act, and the Administrator will, for the purpose of determining
whether a standard under section 112(f) of the Act is necessary, review
emissions from sources granted an alternative emission limitation under
this subpart at the same time that other sources in the category or
subcategory are reviewed.
(f) Nothing in this subpart shall preclude a State from requiring
hazardous air pollutant reductions in excess of 90 percent (95 percent
in the case of particulate hazardous air pollutants) as a condition of
such State granting an alternative emission limitation authorized in
paragraph (a) of this section.
Sec. 63.73 Source.
(a) An alternative emission limitation may be granted under this
subpart to an existing source. For the purposes of this subpart only, a
source is defined as follows:
(1) A building structure, facility, or installation identified as a
source by the EPA in appendix B of this part;
(2) All portions of an entire contiguous plant site under common
ownership or control that emit hazardous air pollutants;
(3) Any portion of an entire contiguous plant site under common
ownership or control that emits hazardous air pollutants and can be
identified as a facility, building, structure, or installation for the
purposes of establishing standards under section 112(d) of the Act; or
(4) Any individual emission point or combination of emission points
within a contiguous plant site under common control, provided that
emission reduction from such point or aggregation of points constitutes
a significant reduction of hazardous air pollutant emissions of the
entire contiguous plant site.
(b) For purposes of paragraph (a)(4) of this section, emissions
reductions are considered significant if they are made
[[Page 109]]
from base year emissions of not less than:
(1) A total of 10 tons per year of hazardous air pollutants where
the total emissions of hazardous air pollutants in the base year from
the entire contiguous plant site is greater than 25 tons per; or
(2) A total of 5 tons per year of hazardous air pollutants where the
total emissions of hazardous air pollutants in the base year from the
entire contiguous plant site is less than or equal to 25 tons per year.
Sec. 63.74 Demonstration of early reduction.
(a) An owner or operator applying for an alternative emission
limitation shall demonstrate achieving early reductions as required by
Sec. 63.72(a)(1) by following the procedures in this section.
(b) An owner or operator shall establish the source for the purposes
of this subpart by documenting the following information:
(1) A description of the source including: a site plan of the entire
contiguous plant site under common control which contains the source,
markings on the site plan locating the parts of the site that constitute
the source, and the activity at the source which causes hazardous air
pollutant emissions;
(2) A complete list of all emission points of hazardous air
pollutants in the source, including identification numbers and short
descriptive titles; and
(3) A statement showing that the source conforms to one of the
allowable definition options from Sec. 63.73. For a source conforming
to the option in Sec. 63.73(a)(4), the total base year emissions from
the source, as determined pursuant to this section, shall be
demonstrated to be at least:
(i) 5 tons per year, for cases in which total hazardous air
pollutant emissions from the entire contiguous plant site under common
control are 25 tons per year or less as calculated under paragraph (1)
of this section; or
(ii) 10 tons per year in all other cases.
(c) An owner or operator shall establish base year emissions for the
source by providing the following information:
(1) The base year chosen, where the base year shall be 1987 or later
except that the base year may be 1985 or 1986 if the owner or operator
of the source can demonstrate that emission data for the source for 1985
or 1986 was submitted to the Administrator pursuant to an information
request issued under section 114 of the Act and was received by the
Administrator prior to November 15, 1990;
(2) The best available data accounting for actual emissions, during
the base year, of all hazardous air pollutants from each emission point
listed in the source in paragraph (b)(2) of this section;
(3) The supporting basis for each emission number provided in
paragraph (c)(2) of this section including:
(i) For test results submitted as the supporting basis, a
description of the test protocol followed, any problems encountered
during the testing, and a discussion of the validity of the method for
measuring the subject emissions; and
(ii) For calculations based on emission factors, material balance,
or engineering principles and submitted as the supporting basis, a step-
by-step description of the calculations, including assumptions used and
their bases, and a brief rationale for the validity of the calculation
method used; and
(4) Evidence that the emissions provided under paragraph (c)(2) of
this section are not artificially or substantially greater than
emissions in other years prior to implementation of emission reduction
measures.
(d) An owner or operator shall establish post-reduction emissions by
providing the following information:
(1) For the emission points listed in the source in paragraph (b)(2)
of this section, a description of all control measures employed to
achieve the emission reduction required by Sec. 63.72(a)(1);
(2) The best available data accounting for actual emissions, during
the year following the applicable emission reduction deadline as
specified in Sec. 63.72(a)(2), of all hazardous air pollutants from
each emission point in the source listed pursuant to paragraph (b)(2) of
this section.
[[Page 110]]
(3) The supporting basis for each emission number provided in
paragraph (d)(2) of this section including:
(i) For test results submitted as the supporting basis, a
description of the test protocol followed, any problems encountered
during the testing, and a discussion of the validity of the method for
measuring the subject emissions; and
(ii) For calculations based on emission factors, material balance,
or engineering principles and submitted as the supporting basis, a step-
by-step description of the calculations, including assumptions used and
their bases, and a brief rationale for the validity of the calculation
method used;
(4) [Reserved]
(5) Evidence that there was no increase in radionuclide emissions
from the source.
(e)(1) An owner or operator shall demonstrate that both total base
year emissions and total base year emissions adjusted for high-risk
pollutants, as applicable, have been reduced by at least 90 percent for
gaseous hazardous air pollutants emitted and 95 percent for particulate
hazardous air pollutants emitted by determining the following for
gaseous and particulate emissions separately:
(i) Total base year emissions, calculated by summing all base year
emission data from paragraph (c)(2) of this section;
(ii) Total post-reduction emissions, calculated by summing all post-
reduction emission data from paragraph (d)(2) of this section;
(iii) (If applicable) Total base year emissions adjusted for high-
risk pollutants, calculated by multiplying each emission number for a
pollutant from paragraph (c)(2) of this section by the appropriate
weighting factor for the pollutant from Table 1 in paragraph (f) of this
section and then summing all weighted emission data;
(iv) (If applicable) Total post-reduction emissions adjusted for
high-risk pollutants, calculated by multiplying each emission number for
a pollutant from paragraph (d)(2) of this section by the appropriate
weighting factor for the pollutant from Table 1 and then summing all
weighted emission data; and
(v) Percent reductions, calculated by dividing the difference
between base year and post-reduction emissions by the base year
emissions. Separate demonstrations are required for total gaseous and
particulate emissions, and total gaseous and particulate emissions
adjusted for high-risk pollutants.
(2) If any points in the source emit both particulate and gaseous
pollutants, as an alternative to the demonstration required in paragraph
(e)(1) of this section, an owner or operator may demonstrate:
(i) A weighted average percent reduction for all points emitting
both particulate and gaseous pollutants where the weighted average
percent reduction is determined by
[GRAPHIC] [TIFF OMITTED] TC21OC91.019
where %W = the required weighted percent reduction
[Sigma] Mg = the total mass rate (e.g., kg/yr) of all gaseous
emissions
[Sigma] Mp = the total mass rate of all particulate emissions
and,
(ii) The reductions required in paragraph (e)(1) of this section for
all other points in the source.
(f) If lower rates or hours are used to achieve all or part of the
emission reduction, any hazardous air pollutant emissions that occur
from a compensating increase in rates or hours from the same activity
elsewhere within the plant site which contains the source shall be
counted in the post-reduction emissions from the source. If emission
reductions are achieved by shutting down process equipment and the
shutdown equipment is restarted or replaced anywhere within the plant
site, any hazardous air pollutant emissions from the restarted or
replacement equipment shall be counted in the post-reduction emissions
for the source.

(g) The best available data representing actual emissions for the
purpose of establishing base year or post-reduction emissions under this
section shall consist of documented results from source tests using an
EPA Reference Method, EPA Conditional Method, or the owner's or
operator's source test method which has been validated pursuant to
Method 301 of appendix A of this part. However, if one of the following
conditions exists, an owner or operator may submit, in lieu of results
from source tests, calculations based on engineering principles,
emission factors, or material balance data as actual emission data for
establishing base year or post-reduction emissions:
(1) No applicable EPA Reference Method, EPA Conditional Method, or
other source test method exists;
(2) It is not technologically or economically feasible to perform
source tests;
(3) It can be demonstrated to the satisfaction of the reviewing
agency that the calculations will provide emission estimates of accuracy
comparable to that of any applicable source test method;
(4) For base year emission estimates only, the base year conditions
no longer exist at an emission point in the source and emission data
could not be produced for such an emission point, by performing source
tests under currently existing conditions and converting the test
results to reflect base year conditions, that is more accurate than an
estimate produced by using engineering principles, emission factors, or
a material balance; or
(5) The emissions from one or a set of emission points in the source
are small compared to total source emissions and potential errors in
establishing emissions from such points will not have a significant
effect on the accuracy of total emissions established for the source.
(h) For base year or post-reduction emissions established under this
section that are not supported by source test data, the source owner or
operator shall include the reason source testing was not performed.
(i) [Reserved]
(j) The EPA average emission factors for equipment leaks cannot be
used under this subpart to establish base year emissions for equipment
leak sources, unless the base year emission number calculated using the
EPA average emission factors for equipment leaks also is used as the
post-reduction emission number for equipment leaks from the source.
(k) A source owner or operator shall not establish base year or
post-reduction emissions that include any emissions from the source
exceeding allowable emission levels specified in any applicable law,
regulation, or permit condition.
(l) For sources subject to paragraph (b)(3)(i) of this section, an
owner or operator shall document total base year emissions from an
entire contiguous plant site under common control by providing the
information required
[[Page 112]]
pursuant to paragraphs (b)(2), (c)(2), and (e)(1)(i) of this section for
all hazardous air pollutants from all emission points in the contiguous
plant site under common control.
(m) If a new pollutant is added to the list of hazardous air
pollutants or high-risk pollutants, any source emitting such pollutant
will not be required to revise an early reduction demonstration pursuant
to this section if:
(1) Alternative emission limits have previously been specified by
permit for the source as provided for in Sec. 63.72(a); or
(2) The base year emissions submitted in an enforceable commitment
have previously been approved by the reviewing agency.

Sec. 63.75 Enforceable commitments.
(a) To make an enforceable commitment an owner or operator shall
submit a commitment to achieve the early reductions required under Sec.
63.72(a)(1) to the appropriate EPA Regional Office and a copy of the
commitment to the appropriate State, except that the commitment shall be
submitted to the State and a copy to the EPA Regional Office if the
State has an approved permitting program under Title V of the Act. A
copy shall also be submitted to both the EPA Stationary Source
Compliance Division (EN-341W), 1200 Pennsylvania Ave., NW., Washington,

other responsible official who can be contacted concerning the
commitment;
(3) An alternative mailing address if correspondence is to be
directed to a location other than that given in paragraph (a)(1) of this
section;
(4) All information specified in Sec. 63.74(b), (c) and (e)(1)(i),
which defines and describes the source and establishes the base year
hazardous air pollutant emissions from the source;
(5) The general plan for achieving the required hazardous air
pollutant emissions reductions at the source including descriptions of
emission control equipment to be employed, process changes or
modifications to be made, and any other emission reduction measures to
be used; and
(6) A statement of commitment, signed by a responsible official of
the source, containing the following:
(i) A statement providing the post-reduction emission levels for
total hazardous air pollutants and high-risk pollutants, as applicable,
from the source on an annual basis which reflect a 90 percent (95
percent for particulate pollutants) reduction from base year emissions;
(ii) A statement certifying that the base year emission data
submitted as part of the enforceable commitment constitute the best
available data for base year emissions from the source, are correct to
the best of the responsible official's knowledge, and are within
allowable levels specified in any applicable law, regulation, or permit;
(iii) A statement that it is understood by the source owner or
operator that submission of base year emissions constitutes a response
to an EPA request under the authority of section 114 of the Act and that
the commitment is subject to enforcement according to Sec. 63.80; and
(iv) A statement committing the source owner or operator to
achieving the emission levels, listed in paragraph (a)(6), (i) of this
section, at the source before January 1, 1994.
(b) The following language may be used to satisfy the requirements
of paragraphs (a)(6)(ii) through (a)(6)(iv) of this section:
I certify to the best of my knowledge that the base year emissions
given above are correct and constitute the best available data for base
year emissions from the source, and acknowledge that these estimates are
being submitted in response to an EPA request under section 114 of the
Act. I further certify that the base year emissions provided for all
emission points in the source do not exceed allowable emission levels
specified in any applicable law, regulation, or permit condition. I
commit to achieve before January 1, 1994, the stated post-reduction
emission level(s) at the source, which will provide the 90 (95) percent
reduction required to qualify for the
[[Page 113]]
compliance extension, and acknowledge that this commitment is
enforceable as specified in title 40, part 63, subpart D, of the Code of
Federal Regulations.
(c) A commitment for a source shall be submitted prior to proposal
of an applicable standard issued under section 112(d) of the Act.
Commitments received after the proposal date shall be void.
(d) If test results for one or more emission points in a source are
required to support base year emissions in an enforceable commitment but
are not available prior to proposal of an applicable standard issued
under section 112(d) of the Act, the test results may be submitted after
the enforceable commitment is made but no later than 180 days after
proposal of an applicable standard. In such cases, the enforceable
commitment shall contain the best substitute emission data for the
points in the source for which test results will be submitted later.
(e) An owner or operator may rescind such a commitment prior to
December 1, 1993 without penalty and forfeit the opportunity to obtain a
six year compliance extension under this subpart.
(f) An enforceable commitment submitted under this section shall not
be in effect and enforceable until the base year emissions contained in
the commitment have been approved according to the procedures in Sec.
63.76. An owner or operator is under no obligation to continue to seek
approval of commitments that have not been approved by December 1, 1993.
(g) The control measure information required under Sec. 63.74(d)(1)
as part of post-reduction emission documentation and submitted in a
permit application according to the provisions of Sec. 63.77 shall
become part of an existing enforceable commitment upon receipt of the
permit application by the permitting authority. An owner or operator
shall notify the permitting authority of any change made to the source
during calendar year 1994 which affects such control measure information
and shall mail the notice within 5 days (postmark date) of making the
change. The notice shall be considered an amendment to the source's
enforceable commitment.
[57 FR 61992, Dec. 29, 1992, as amended at 58 FR 34370, June 25, 1993;
58 FR 62543, Nov. 29, 1993; 59 FR 59924, Nov. 21, 1994]
Sec. 63.76 Review of base year emissions.
(a) Pursuant to the procedures of this section, the appropriate
reviewing agency shall review and approve or disapprove base year
emission data submitted in an enforceable commitment under Sec. 63.75
or in a request letter from an applicant that wishes to participate in
the early reduction program but who is not required to submit an
enforceable commitment. For review requests submitted to a State agency
as the appropriate reviewing agency, a copy of the request also shall be
submitted to the applicable EPA Regional Office. For review requests
submitted to the EPA Regional Office as the appropriate reviewing
agency, a copy of the request also shall be sent to the applicable State
agency. Copies also shall be submitted to the EPA Stationary Source
Compliance Division (EN-341W), 1200 Pennsylvania Ave., NW., Washington,
DC 20460 and the EPA Emission Standards Division (MD-13), Research
Triangle Park, NC 27711; to the attention of the Early Reductions
Officer.
(b) Within 30 days of receipt of an enforceable commitment or base
year emission data, the reviewing agency shall advise the applicant
that:
(1) The base year emission data are complete as submitted; or
(2) The base year emission data are not complete and include a list
of deficiencies that must be corrected before review can proceed.
(c) EPA will publish a notice in the Federal Register which contains
a list, accumulated for the previous month, of the sources for which
complete base year emission data have been submitted and which are
undergoing review either in the EPA Regional Office or a State agency
within the EPA region. The notice will contain the name and location of
each source and a contract in the EPA Regional Office for additional
information.
(d) Within 60 days of a determination that a base year emission data
submission is complete, the reviewing agency
[[Page 114]]
shall evaluate the adequacy of the submission with respect to the
requirements of Sec. 63.74 (b) and (c) and either:
(1) Determine to approve the submission and publish a notice in a
newspaper of general circulation in the area where the source is located
or in a State publication designed to give general public notice,
providing the aggregate base year emission data for the source and the
rationale for the proposed approval, noting the availability of the
nonconfidential information contained in the submission for public
inspection in at least one location in the community in which the source
is located, providing for a public hearing upon request by an interested
party, and establishing a 30 day public comment period that can be
extended to 60 days upon request by an interested party; or
(2) Determine to disapprove the base year emission data and give
notice to the applicant of the reasons for the disapproval. An applicant
may correct disapproved base year data and submit revised data for
review in accordance with this subsection, except that the review of a
revision shall be accomplished within 30 days.
(e) If no adverse public comments are received by the reviewing
agency on proposed base year data for a source, the data shall be
considered approved at the close of the public comment period and a
notice of the approval shall be sent to the applicant and published by
the reviewing agency by advertisement in the area affected.
(f) If adverse comments are received and the reviewing agency agrees
that corrections are needed, the reviewing agency shall give notice to
the applicant of the disapproval and reasons for the disapproval. An
applicant may correct disapproved base year emission data and submit
revised emission data. If a revision is submitted by the applicant that,
to the satisfaction of the reviewing agency, takes into account the
adverse comments, the reviewing agency will publish by advertisement in
the area affected a notice containing the approved base year emission
data for the source and send notice of the approval to the applicant.
(g) If adverse comments are received and the reviewing agency
determines that the comments do not warrant changes to the base year
emission data, the reviewing agency will publish by advertisement in the
area affected a notice containing the approved base year emission data
for the source and the reasons for not accepting the adverse comments. A
notice of the approval also shall be sent to the applicant.
(h) If an applicant submits revised emission data under paragraph
(d)(2) or (f) of this section for a source subject to an enforceable
commitment, the applicant also shall submit an amended enforceable
commitment which takes into account the revised base year emissions.
(i) If revised base year emission data are not submitted or notice
of intent to submit revised data is not provided to the permitting
authority by an applicant within 90 days of receiving adverse comments
or a notice of disapproved base year emission data for a source that is
subject to an enforceable commitment, the enforceable commitment shall
be considered withdrawn and a notice to that effect shall be sent by the
reviewing agency to the applicant.
Sec. 63.77 Application procedures.
(a) To apply for an alternative emission limitation under Sec.
63.72, an owner or operator of the source shall file a permit
application with the appropriate permitting authority.
(b) Except as provided in paragraph (e) of this section, the permit
application shall contain the information required by Sec. 63.74, as
applicable, and the additional information required for a complete
permit application as specified by the applicable permit program
established pursuant to title V of the Act.
(c) Permit applications under this section for sources not subject
to enforceable commitments shall be submitted by the later of the
following dates:
(1) 120 days after proposal of an otherwise applicable standard
issued under section 112(d) of the Act; or
(2) 120 days after the date an applicable permit program is approved
or established pursuant to title V of the Act.
[[Page 115]]
(d) Permit applications for sources subject to enforceable
commitments pursuant to Sec. 63.75 shall be submitted no later than
April 30, 1994.
(e) If the post-reduction year does not end at least one month
before the permit application deadline under paragraph (c) of this
section, the source may file the post-reduction emissions information
required under Sec. 63.74(d)(2), (d)(3), and (d)(5) later as a
supplement to the original permit application. In such cases, this
supplemental information shall be submitted to the permitting authority
no later than one month after the end of the post-reduction year.
(f) If a source test will be the supporting basis for establishing
post-reduction emissions for one or more emissions units in the early
reductions source, the test results shall be submitted by the applicable
deadline for submittal of a permit application as specified in paragraph
(c) or (d) of this section.
(g) Review and disposition of permit applications submitted under
this section will be accomplished according to the provisions of the
applicable permit program established pursuant to title V of the Act.
[58 FR 62543, Nov. 29, 1993, as amended at 59 FR 59924, Nov. 21, 1994]
Sec. 63.78 Early reduction demonstration evaluation.
(a) The permitting authority will evaluate an early reduction
demonstration submitted by the source owner or operator in a permit
application with respect to the requirements of Sec. 63.74.
(b) An application for a compliance extension may be denied if, in
the judgement of the permitting authority, the owner or operator has
failed to demonstrate that the requirements of Sec. 63.74 have been
met. Specific reasons for denial include, but are not limited to:
(1) The information supplied by the owner or operator is incomplete;
(2) The required 90 percent reduction (95 percent in cases where the
hazardous air pollutant is particulate matter) has not been
demonstrated;
(3) The base year or post-reduction emissions are incorrect, based
on methods or assumptions that are not valid, or not sufficiently
reliable or well documented to determine with reasonable certainty that
required reductions have been achieved; or
(4) The emission of hazardous air pollutants or the performance of
emission control measures is unreliable so as to preclude determination
that the required reductions have been achieved or will continue to be
achieved during the extension period.
Sec. 63.79 Approval of applications.
(a) If an early reduction demonstration is approved and other
requirements for a complete permit application are met, the permitting
authority shall establish by a permit issued pursuant to title V of the
Act enforceable alternative emissions limitations for the source
reflecting the reduction which qualified the source for the extension.
However, if it is not feasible to prescribe a numerical emissions
limitation for one or more emission points in the source, the permitting
authority shall establish such other requirements, reflecting the
reduction which qualified the source for an extension, in order to
assure the source achieves the 90 percent or 95 percent reduction, as
applicable.
(b) An alternative emissions limitation or other requirement
prescribed pursuant to paragraph (a) of this section shall be effective
and enforceable immediately upon issuance of the permit for the source
and shall expire exactly six years after the compliance date of an
otherwise applicable standard issued pursuant to section 112(d) of the
Act.
Sec. 63.80 Enforcement.
(a) All base year or post-reduction emissions information described
in Sec. 63.74 and required to be submitted as part of a permit
application under Sec. 63.77 or an enforceable commitment under Sec.
63.75 shall be considered to have been requested by the Administrator
under the authority of section 114 of the Act.
(b) Fraudulent statements contained in any base year or post-
reduction emissions submitted to a State or EPA Regional Office under
this subpart shall be considered violations of section 114 of the Act
and of this subpart
[[Page 116]]
and, thus, actionable under section 113 of the Act and can be
considered, in appropriate cases, violations of 18 U.S.C. 1001, the
general false swearing provision of the United States Code.
(c) If a source subject to an enforceable commitment fails to
achieve reductions before January 1, 1994, sufficient to qualify the
source for an extension under this subpart, the source shall be
considered to be in violation of the commitment and shall be subject to
enforcement action under section 113 of the Act.
(d) If an early reduction demonstration in a permit application
filed under Sec. 63.77 is disapproved for a source not subject to an
enforceable commitment, the owner or operator shall comply with an
applicable standard issued under section 112(d) of the Act by the
compliance date specified in such standard.
(e) If an early reduction demonstration in a permit application
filed under Sec. 63.77 is disapproved for a source that is subject to
an enforceable commitment, the owner or operator shall comply with an
applicable standard issued under section 112(d) of the Act by the
compliance date specified in such standard and will be subject to
enforcement action under section 113 of the Act.
(f) A violation of an alternative emission limitation or other
requirement established by permit under Sec. 63.79 (a) or (b) for the
source is enforceable pursuant to the authority of section 113 of the
Act notwithstanding any demonstration of continuing 90 percent (95
percent for hazardous air pollutants which are particulates) emission
reduction over the entire source.
Sec. 63.81 Rules for special situations.
(a) If more than one standard issued under section 112(d) of the Act
would be applicable to a source as defined under Sec. 63.73, then the
date of proposal referred to in Sec. Sec. 63.72(a)(2), 63.72(c),
63.74(d)(4), 63.75(c), and 63.77(c) is the date the first applicable
standard is proposed.
(b) Sources emitting radionuclides are not required to reduce
radionuclides by 90 (95) percent. Radionuclides may not be increased
from the source as a result of the early reductions demonstration.
Subpart E_Approval of State Programs and Delegation of Federal
Authorities
Sec. 63.90 Program overview.
The regulations in this subpart establish procedures consistent with
section 112(l) of the Clean Air Act (Act) (42 U.S.C. 7401-7671q). This
subpart establishes procedures for the approval of State rules,
programs, or other requirements such as permit terms and conditions to
be implemented and enforced in place of certain otherwise applicable
section 112 Federal rules, emission standards, or requirements
(including section 112 rules promulgated under the authority of the Act
prior to the 1990 Amendments to the Act). The authority to implement and
enforce section 112 Federal rules as promulgated without changes may be
delegated under procedures established in this subpart. In this process,
States may seek approval of a State mechanism for receiving delegation
of existing and future unchanged Federal section 112 standards. This
subpart clarifies which part 63, subpart A General Provisions
authorities can be delegated to States. This subpart also establishes
procedures for the review and withdrawal of section 112 implementation
and enforcement authorities delegated through this subpart. This subpart
also establishes procedures for the approval of State rules or programs
to establish limitations on the potential to emit pollutants listed in
or pursuant to section 112(b) of the Act.
(a) Definitions. The following definitions apply to this subpart.
Alternative requirements means the requirements, rules, permits,
provisions, methods, or other enforceable mechanisms that a State
submits for approval under this subpart or subpart A and, after
approval, replaces the otherwise applicable Federal section 112
requirements, provisions, or methods.
Applicability criteria means the regulatory criteria used to define
all affected sources subject to a specific section 112 rule.
Approval means a determination by the Administrator that a State
rule,
[[Page 117]]
program, or requirement meets the criteria of Sec. 63.91 and the
additional criteria of either Sec. 63.92, Sec. 63.93, Sec. 63.94, or
Sec. 63.97 as appropriate. For accidental release prevention programs,
the criteria of Sec. 63.95 must be met in addition to the criteria of
Sec. 63.91. This is considered a ``full approval'' for the purposes of
this subpart. Partial approvals may also be granted as described in this
subpart. Any approved requirements become applicable requirements under
Sec. 70.2 of this chapter.
Compliance and enforcement measures means requirements relating to
compliance and enforcement, including but not necessarily limited to
monitoring methods and procedures, recordkeeping, reporting, plans,
inspection, maintenance, and operation requirements, pollution
prevention requirements, noticing, field inspections, entry, sampling,
or accidental release prevention oversight.
Intermediate change to monitoring means a modification to federally
required monitoring involving ``proven technology'' (generally accepted
by the scientific community as equivalent or better) that is applied on
a site-specific basis and that may have the potential to decrease the
stringency of the associated emission limitation or standard. Though
site-specific, an intermediate change may set a national precedent for a
source category and may ultimately result in a revision to the federally
required monitoring. Examples of intermediate changes to monitoring
include, but are not limited to:
(1) Use of a continuous emission monitoring system (CEMS) in lieu of
a parameter monitoring approach;
(2) Decreased frequency for non-continuous parameter monitoring or
physical inspections;
(3) Changes to quality control requirements for parameter
monitoring; and
(4) Use of an electronic data reduction system in lieu of manual
data reduction.
Intermediate change to test method means a within-method
modification to a federally enforceable test method involving ``proven
technology'' (generally accepted by the scientific community as
equivalent or better) that is applied on a site-specific basis and that
may have the potential to decrease the stringency of the associated
emission limitation or standard. Though site-specific, an intermediate
change may set a national precedent for a source category and may
ultimately result in a revision to the federally enforceable test
method. In order to be approved, an intermediate change must be
validated according to EPA Method 301 (Part 63, Appendix A) to
demonstrate that it provides equal or improved accuracy and precision.
Examples of intermediate changes to a test method include, but are not
limited to:
(1) Modifications to a test method's sampling procedure including
substitution of sampling equipment that has been demonstrated for a
particular sample matrix, and use of a different impinger absorbing
solution;
(2) Changes in sample recovery procedures and analytical techniques,
such as changes to sample holding times and use of a different
analytical finish with proven capability for the analyte of interest;
and
(3) ``Combining'' a federally required method with another proven
method for application to processes emitting multiple pollutants.
Level of control means the degree to which a rule, program, or
requirement limits emissions or employs design, equipment, work
practice, or operational standards, accident prevention, or other
requirements or techniques (including a prohibition of emissions) for:
(1)(i) Each hazardous air pollutant, if individual pollutants are
subject to emission limitations, and
(ii) The aggregate total of hazardous air pollutants, if the
aggregate grouping is subject to emission limitations, provided that the
rule, program, or requirement would not lead to an increase in risk to
human health or the environment; and
(2) Each substance regulated under part 68 of this chapter.
(3) Test methods and associated procedures and averaging times are
integral to the level of control.
Local agency means a local air pollution control agency or, for the
purposes of Sec. 63.95, any local agency or entity having
responsibility for preventing accidental releases which may occur at
[[Page 118]]
a source regulated under part 68 of this chapter.
Major change to monitoring means a modification to federally
required monitoring that uses ``unproven technology or procedures'' (not
generally accepted by the scientific community) or is an entirely new
method (sometimes necessary when the required monitoring is unsuitable).
A major change to monitoring may be site-specific or may apply to one or
more source categories and will almost always set a national precedent.
Examples of major changes to monitoring include, but are not limited to:
(1) Use of a new monitoring approach developed to apply to a control
technology not contemplated in the applicable regulation;
(2) Use of a predictive emission monitoring system (PEMS) in place
of a required continuous emission monitoring system (CEMS);
(3) Use of alternative calibration procedures that do not involve
calibration gases or test cells;
(4) Use of an analytical technology that differs from that specified
by a performance specification;
(5) Decreased monitoring frequency for a continuous emission
monitoring system, continuous opacity monitoring system, predictive
emission monitoring system, or continuous parameter monitoring system;
(6) Decreased monitoring frequency for a leak detection and repair
program; and
(7) Use of alternative averaging times for reporting purposes.
Major change to recordkeeping/reporting means:
(1) A modification to federally required recordkeeping or reporting
that:
(i) May decrease the stringency of the required compliance and
enforcement measures for the relevant standards;
(ii) May have national significance (e.g., might affect
implementation of the applicable regulation for other affected sources,
might set a national precedent); or
(iii) Is not site-specific.
(2) Examples of major changes to recordkeeping and reporting
include, but are not limited to:
(i) Decreases in the record retention for all records;
(ii) Waiver of all or most recordkeeping or reporting requirements;
(iii) Major changes to the contents of reports; or
(iv) Decreases in the reliability of recordkeeping or reporting
(e.g., manual recording of monitoring data instead of required automated
or electronic recording, or paper reports where electronic reporting may
have been required).
Major change to test method means a modification to a federally
enforceable test method that uses ``unproven technology or procedures''
(not generally accepted by the scientific community) or is an entirely
new method (sometimes necessary when the required test method is
unsuitable). A major change to a test method may be site-specific, or
may apply to one or more sources or source categories, and will almost
always set a national precedent. In order to be approved, a major change
must be validated according to EPA Method 301 (part 63, appendix A).
Examples of major changes to a test method include, but are not limited
to:
(1) Use of an unproven analytical finish;
(2) Use of a method developed to fill a test method gap;
(3) Use of a new test method developed to apply to a control
technology not contemplated in the applicable regulation; and
(4) Combining two or more sampling/analytical methods (at least one
unproven) into one for application to processes emitting multiple
pollutants.
Minor change to monitoring means:
(1) A modification to federally required monitoring that:
(i) Does not decrease the stringency of the compliance and
enforcement measures for the relevant standard;
(ii) Has no national significance (e.g., does not affect
implementation of the applicable regulation for other affected sources,
does not set a national precedent, and individually does not result in a
revision to the monitoring requirements); and
(iii) Is site-specific, made to reflect or accommodate the
operational characteristics, physical constraints, or safety concerns of
an affected source.
[[Page 119]]
(2) Examples of minor changes to monitoring include, but are not
limited to:
(i) Modifications to a sampling procedure, such as use of an
improved sample conditioning system to reduce maintenance requirements;
(ii) Increased monitoring frequency; and
(iii) Modification of the environmental shelter to moderate
temperature fluctuation and thus protect the analytical instrumentation.
Minor change to recordkeeping/reporting means:
(1) A modification to federally required recordkeeping or reporting
that:
(i) Does not decrease the stringency of the compliance and
enforcement measures for the relevant standards;
(ii) Has no national significance (e.g., does not affect
implementation of the applicable regulation for other affected sources,
does not set a national precedent, and individually does not result in a
revision to the recordkeeping or reporting requirement); and
(iii) Is site-specific.
(2) Examples of minor changes to recordkeeping or reporting include,
but are not limited to:
(i) Changes to recordkeeping necessitated by alternatives to
monitoring;
(ii) Increased frequency of recordkeeping or reporting, or increased
record retention periods;
(iii) Increased reliability in the form of recording monitoring
data, e.g., electronic or automatic recording as opposed to manual
recording of monitoring data;
(iv) Changes related to compliance extensions granted pursuant to
Sec. 63.6(i);
(v) Changes to recordkeeping for good cause shown for a fixed short
duration, e.g., facility shutdown;
(vi) Changes to recordkeeping or reporting that is clearly redundant
with equivalent recordkeeping/reporting requirements; and
(vii) Decreases in the frequency of reporting for area sources to no
less than once a year for good cause shown, or for major sources to no
less than twice a year as required by title V, for good cause shown.
Minor change to test method means:
(1) A modification to a federally enforceable test method that:
(i) Does not decrease the stringency of the emission limitation or
standard;
(ii) Has no national significance (e.g., does not affect
implementation of the applicable regulation for other affected sources,
does not set a national precedent, and individually does not result in a
revision to the test method); and
(iii) Is site-specific, made to reflect or accommodate the
operational characteristics, physical constraints, or safety concerns of
an affected source.
(2) Examples of minor changes to a test method include, but are not
limited to:
(i) Field adjustments in a test method's sampling procedure, such as
a modified sampling traverse or location to avoid interference from an
obstruction in the stack, increasing the sampling time or volume, use of
additional impingers for a high moisture situation, accepting
particulate emission results for a test run that was conducted with a
lower than specified temperature, substitution of a material in the
sampling train that has been demonstrated to be more inert for the
sample matrix; and
(ii) Changes in recovery and analytical techniques such as a change
in quality control/quality assurance requirements needed to adjust for
analysis of a certain sample matrix.
Partial approval means that the Administrator approves under this
subpart:
(1) A State's legal authorities that fully meet the criteria of
Sec. 63.91(d)(3)(ii)-(v), and substantially meet the criteria of Sec.
63.91(d)(3)(i) as appropriate; or
(2) A State rule or program that meets the criteria of Sec. 63.92,
Sec. 63.93, Sec. 63.94, Sec. 63.95, or Sec. 63.97 with the exception
of a separable portion of that State rule or program which fails to meet
those criteria. A separable portion of a State rule or program is
defined as a section(s) of a rule or a portion(s) of a program which can
be acted upon independently without affecting the overall integrity of
the rule or program as a whole.
Program means, for the purposes of an approval under this subpart, a
collection of State authorities, resources, and other requirements that
satisfy
[[Page 120]]
the criteria of this subpart and subpart A.
State agency, for the purposes of this subpart, includes State and
local air pollution agencies, Indian tribes as defined in Sec. 71.2 of
this chapter, and territories of the United States to the extent they
are or will be delegated Federal section 112 rules, emission standards,
or requirements.
Stringent or stringency means the degree of rigor, strictness or
severity a statute, rule, emission standard, or requirement imposes on
an affected source as measured by the quantity of emissions, or as
measured by parameters relating to rule applicability and level of
control, or as otherwise determined by the Administrator.
Title V operating permit programs means the part 70 permitting
program and the delegated Indian tribal programs under part 70 of this
chapter.
(b) Local agency coordination with State and territorial agencies.
Local agencies submitting a rule or program for approval under this
subpart shall consult with the relevant State or Territorial agency
prior to making a request for approval to the Administrator. A State or
Territorial agency may submit requests for approval on behalf of a local
agency after consulting with that local agency.
(c) Tribal authority. A tribal authority may submit a rule or
program under this subpart, provided that the tribal authority has
received approval, under the provisions of part 49 of this chapter, for
administering Federal rules under section 112 of the Act.
(d) Authorities retained by the Administrator. (1) The following
authorities will be retained by the Administrator and will not be
delegated:
(i) The authority to add or delete pollutants from the list of
hazardous air pollutants established under section 112(b);
(ii)-(iii) [Reserved]
(iv) The authority to add source categories to or delete source
categories from the Federal source category list established under
section 112(c)(1) or to subcategorize categories on the Federal source
category list after proposal of a relevant emission standard;
(v) The authority to revise the source category schedule established
under section 112(e) by moving a source category to a later date for
promulgation; and
(vi) Any other authorities determined to be nondelegable by the
Administrator.
(2) Nothing in this subpart shall prohibit the Administrator from
enforcing any applicable rule, emission standard or requirement
established under section 112.
(3) Nothing in this subpart shall affect the authorities and
obligations of the Administrator or the State under title V of the Act
or under regulations promulgated pursuant to that title.
(e) Federally-enforceable requirements. All rules, programs, State
or local permits, or other requirements approved under this subpart and
all resulting part 70 operating permit conditions are enforceable by the
Administrator and by citizens under the Act.
(f) Standards not subject to modification or substitution. With
respect to radionuclide emissions from licensees of the Nuclear
Regulatory Commission or licensees of Nuclear Regulatory Commission
Agreement States which are subject to part 61, subparts I, T, or W of
this chapter, a State may request that the EPA approve delegation of
implementation and enforcement of the Federal standard pursuant to Sec.
63.91, but no changes or modifications in the form or content of the
standard will be approved pursuant to Sec. 63.92, Sec. 63.93, Sec.
63.94, or Sec. 63.97.
(g) Selection of delegation options. (1) With the exception of
paragraphs (g)(2) and (g)(3) of this section, States may only submit
requests for approval of alternative requirements for a section 112
Federal rule, emission standard, or other requirement under a single
delegation option under this subpart.
(2) In the case of Sec. 63.94 submittals, if the identified sources
in any source category comprise a subset of the sources in that
category, the State must accept delegation under one other section of
this subpart for the remainder of the sources in that category that are
required to be permitted by the State under part 70 of this chapter.
(3) If the Administrator partially approves the State request per
Sec. 63.91(f), the State may submit a request for the remaining section
112 rules, emission
[[Page 121]]
standards, or requirements in that category under another section of
this subpart.
[65 FR 55835, Sept. 14, 2000]
Sec. 63.91 Criteria for straight delegation and criteria
common to all approval options.
(a) Applicable approval criteria. A State must satisfy the criteria
in paragraph (d) of this section for up-front approval to obtain
delegation of the Federal section 112 rules, emission standards, or
requirements. Once a State has demonstrated it meets the criteria in
paragraph (d) of this section, it only needs to reference that
demonstration and reaffirm that it still meets the criteria in future
submittals. In addition, a State must satisfy the applicable approval
criteria in Sec. 63.92, Sec. 63.93, Sec. 63.94, Sec. 63.95, or Sec.
63.97, as specified in the following paragraphs.
(1) Unchanged Federal section 112 rules (``straight delegation'').
To obtain approval of State programs to implement and enforce Federal
section 112 rules as promulgated without changes (except for accidental
release programs, described in paragraph (a)(4) of this section), only
the criteria of paragraph (d) of this section must be met. This includes
State requests for one-time approval of their mechanism for taking
delegation of future unchanged Federal section 112 rules, emission
standards, and requirements as well as approval to implement and enforce
unchanged Federal section 112 rules, emission standards, and
requirements on a rule-by-rule basis.
(2) State rules, programs, or requirements that are different from
the Federal rule. To obtain approval under this subpart of a rule,
program, or requirement that is different from the Federal section 112
rule, emission standard, or requirement, the criteria of paragraph (d)
of this section and the criteria of either Sec. 63.92, Sec. 63.93,
Sec. 63.94, or Sec. 63.97 must be met.
(3) Separable portions of State rules, programs, or requirements
(``partial approval''). To obtain partial approval under this subpart, a
State request must meet the criteria in paragraphs (d) and (f) of this
section.
(4) Programs under part 68 of this chapter, prevention of accidental
releases. For approval of State rules or programs to implement and
enforce the Federal accidental release prevention program in part 68 of
this chapter, as promulgated without changes, the provisions of
paragraph (d) of this section, and Sec. 63.95 must be met. For approval
of alternative requirements, the provisions of either Sec. 63.92 or
Sec. 63.93 must also be met.
(5) Limits on the potential to emit section 112 pollutants. The
Administrator may, under the authority of section 112(l) and this
subpart, also approve a State program designed to establish limits on
the potential to emit hazardous air pollutants listed pursuant to
section 112 of the Act.
(b) Approval process. When a State submits an initial request for
approval, and except as otherwise specified under Sec. 63.92, Sec.
63.93, Sec. 63.94, Sec. 63.95, or Sec. 63.97, for a State's
subsequent requests for approval, the approval process will be as shown
in the following table:

------------------------------------------------------------------------
(c) Enforcement. (1) Approval of the alternative rule, program, or
requirement delegates to the State the authority to implement and
enforce the approved rule, program, or requirement in lieu of the
otherwise applicable Federal section 112 rule, emission standard, or
requirement.
(i) The approved State rule, program, or requirement shall be
federally enforceable from the date the Administrator signs the
approval, with two exceptions. For States that implement unchanged
Federal requirements (Sec. 63.91, straight delegation) via their title
V permit program, and for States using the equivalency by permit option
(63.94), the approved requirements shall be federally enforceable on the
date of issuance or revision of the title V permit.
(ii) In the case of a partial approval under paragraph (f)(1) of
this section, only those authorities of the State request found to meet
the requirements of this section will be approved; the remaining Federal
authorities will be implemented and enforced by EPA.
(iii) For partial approvals under paragraph (f)(3) of this section,
only the portion of the State rule that is approved will be federally
enforceable; the remainder continues to be State enforceable only.
(2) When a State rule, program, or requirement is approved by the
Administrator under this subpart, applicable title V permits shall be
revised according to the provisions of Sec. 70.7(f) of this chapter.
(i) Each permit shall specify the origin of the alternative
conditions per Sec. 70.6 (a)(i) of this chapter and specifically
reference the Federal Register notice or other EPA approval mechanism in
the permit.
(ii) When approved alternative requirements are incorporated in a
permit, those requirements must be clearly identified and carried
forward in any subsequent permit revisions or renewals. If the permit is
not renewed, or if a revision or renewal does not carry the alternate
requirements forward, then the Federal section 112 requirements become
the applicable requirements.
(3) If approval is withdrawn under Sec. 63.96, all otherwise
applicable Federal rules and requirements shall be enforceable in
accordance with the compliance schedule established in the withdrawal
notice and relevant title V permits shall be revised according to the
provisions of Sec. 70.7(f) of this chapter.
(d) Criteria for approval. (1) Any request for approval under this
subpart shall meet all section 112(l) approval criteria specified by the
otherwise applicable Federal section 112 rule, emission standard, or
requirement, all of the approval criteria of this section, and any
additional approval criteria in Sec. 63.92, Sec. 63.93, Sec. 63.94,
Sec. 63.95, or Sec. 63.97.
(2) Once a State has satisfied the Sec. 63.91(d) up-front approval
requirements, it only needs to reference the previous demonstration and
reaffirm that is still meets the criteria for any subsequent equivalency
submittals.
(3) Interim or final title V program approval will satisfy the
criteria set
[[Page 123]]
forth in Sec. 63.91(d), up-front approval criteria. Alternatively, the
State must provide the following items in paragraphs (d)(3)(i) through
(v) of this section to the Administrator:
(i) A written finding by the State Attorney General (or for a local
agency or tribal authority, the General Counsel with full authority to
represent the local agency or tribal authority) that the State has the
necessary legal authority to implement and to enforce the State rule,
program, or requirement upon approval and to assure compliance by all
sources within the State with each applicable section 112 rule, emission
standard, or requirement. For full approval, the State must have the
following legal authorities concerning enforcement and compliance
assurance:
(A) The State shall have enforcement authorities that meet the
requirements of Sec. 70.11 of this chapter, except that tribal
authorities shall have enforcement authorities that meet the
requirements of part 49 of this chapter, the Tribal Air Rule.
(B) The State shall have authority to request information from
regulated sources regarding their compliance status.
(C) The State shall have authority to inspect sources and any
records required to determine a source's compliance status.
(D) If a State delegates authorities to a local agency, the State
must retain enforcement authority unless the local agency has
authorities that meet the requirements of Sec. 70.11 of this chapter.
(ii) A copy of State statutes, regulations, and requirements that
contain the appropriate provisions granting authority to implement and
enforce the State rule, program, or requirement upon approval.
(iii) A demonstration that the State has adequate resources to
implement and enforce all aspects of the rule, program, or requirement
upon approval (except for authorities explicitly retained by the
Administrator, such as those pursuant to paragraph (f) of this section
or pursuant to part 49 of this chapter), which includes:
(A) A description in narrative form of the scope, structure,
coverage, and processes of the State program.
(B) A description of the organization and structure of the agency or
agencies that will have responsibility for administering the program.
(C) A description of the agency's capacity to carry out the State
program, including the number, occupation, and general duties of the
employees.
(iv) A schedule demonstrating expeditious State implementation of
the rule, program, or requirement upon approval.
(v) A plan that assures expeditious compliance by all sources
subject to the State rule, program, or requirement upon approval. The
plan should include, at a minimum, a complete description of the State's
compliance tracking and enforcement program, including but not limited
to inspection strategies.
(4) If any of the State documents that are required to support an
approval under this subpart are readily available to the EPA and to the
public, the State may cite the relevant portions of the documents or
indicate where they are available (e.g., by providing an Internet
address) rather than provide copies.
(5) Electronic documents. Submission of electronic documents shall
comply with the requirements of 40 CFR part 3--(Electronic reporting).
(e) Revisions. Within 90 days of any State amendment, repeal, or
revision of any State rule, program, permit, or other requirement
approved as an alternative to a Federal requirement or part of the
authority necessary for the up-front approval, the State must provide
the Administrator with a copy of the revised authorities and meet the
requirements of either paragraph (e)(1) or (e)(2) of this section.
(1)(i) The State shall provide the Administrator with a written
finding by the State Attorney General (or for a local agency or tribal
authority, the General Counsel with full authority to represent the
local agency or tribal authority) that the State's revised legal
authorities are adequate to continue to implement and to enforce all
previously approved State rules and the approved State program (as
applicable) and adequate to continue to assure compliance by all sources
within the
[[Page 124]]
State with approved rules, the approved program, the approved permit, or
other requirements (as applicable) and each applicable section 112 rule,
emission standard, or requirement.
(ii) If the Administrator determines that the written finding is not
adequate, the State shall request approval of the revised rule, program,
permit, or other requirement according to the provisions of paragraph
(e)(2) of this section.
(2) The State shall request approval under this subpart for any
revised rule, program, permit, or other requirement.
(i) If the Administrator approves the revised rule, program, permit,
or other requirement, the revision will replace the previously approved
rule, program, permit, or other requirement.
(ii) If the Administrator disapproves the revised rule, program,
permit, or other requirement, the Administrator will initiate procedures
under Sec. 63.96 to withdraw approval of any previously approved rule,
program, permit, or other requirement that may be affected by the
revised authorities.
(iii) Until such time as the Administrator approves or withdraws
approval of a revised rule, program, permit, or other requirement, the
previously approved rule, program, permit, or requirement remains
federally enforceable and the revision is not federally enforceable.
(3) If the EPA amends, or otherwise revises a promulgated section
112 rule or requirement in a way that increases its stringency, the EPA
will notify any State which has received delegation under this subpart
of the need to revise their equivalency demonstration.
(i) The EPA Regional Office will consult with the affected State(s)
to set a time frame for the State(s) to submit a revised equivalency
demonstration.
(ii) The revised equivalency demonstration will be reviewed and
approved or disapproved according to the procedures set forth in this
section and Sec. 63.91, Sec. 63.92, Sec. 63.93, Sec. 63.94, Sec.
63.95, or Sec. 63.97, whichever are applicable.
(f) Partial approval. The partial approval process under this
subpart is described in the following table:
------------------------------------------------------------------------
If . . . Then . . . And . . .

Sec. 63.92 Approval of State requirements that adjust a section 112 rule.
Under this section a State may seek approval of State requirements
that make pre-approved adjustments to a Federal section 112 rule,
emission standard, or requirement that are unambiguously no less
stringent than the Federal rule, emission standard, or requirement.
(a) Approval process. (1) If the Administrator finds that the
criteria of this section and the criteria of Sec. 63.91 are met, the
Administrator will approve the State requirements, publish them in the
Federal Register, and incorporate them, directly or by reference, in the
appropriate subpart of part 63, without additional notice and
opportunity for comment. Requirements approved under Sec. 63.95 will be
incorporated pursuant to requirements under part 68 of this chapter.
(2) If the Administrator finds that any one of the State adjustments
to
[[Page 126]]
the Federal rule is in any way ambiguous with respect to the stringency
of applicability, level of control, compliance and enforcement measures,
or the compliance date for any affected source or emission point, the
Administrator will either disapprove the State request or consider the
request under Sec. 63.93.
(3) Within 60 days of receiving a complete request for approval
under this section, the Administrator will either approve or disapprove
the State request. If approved, the change will be effective upon
signature of the Federal Register notice.
(4) Requirements submitted for approval under this section shall
include either title V permits, title V general permits, Federal new
source review permits, or State rules. Permits must already be issued to
be used under this section.
(5) If the State uses a permit as the basis of alternative
requirements under this section, the relevant permit terms and
conditions must remain applicable to the source, even if the source
takes steps that would otherwise release it from an obligation to have a
permit.
(b) Criteria for approval. Any request for approval under this
section shall meet all of the criteria of this section and Sec. 63.91
before approval. The State shall provide the Administrator with:
(1) A demonstration that the public within the State has had
adequate notice and opportunity to submit written comment on the State
requirements, and
(2) A demonstration that each State adjustment to the Federal rule
individually results in requirements that:
(i) Are unequivocally no less stringent than the otherwise
applicable Federal rule with respect to applicability;
(ii) Are unequivocally no less stringent than the otherwise
applicable Federal rule with respect to level of control for each
affected source and emission point;
(iii) Are unequivocally no less stringent than the otherwise
applicable Federal rule with respect to compliance and enforcement
measures for each affected source and emission point; and
(iv) Assure compliance by every affected source no later than would
be required by the otherwise applicable Federal rule.
(3) State adjustments to Federal section 112 rules which may be part
of an approved rule under this section are:
(i) Lowering a required emission rate or de minimis level;
(ii) Adding a design, work practice, operational standard, emission
rate or other such requirement;
(iii) Increasing a required control efficiency;
(iv) Increasing the frequency of required reporting, testing,
sampling or monitoring;
(v) Adding to the amount of information required for records or
reports;
(vi) Decreasing the amount of time to come into compliance;
(vii) Subjecting additional emission points or sources within a
source category to control requirements;
(viii) Any adjustments allowed in a specific section 112 rule;
(ix) Minor editorial, formatting, and other nonsubstantive changes;
or
(x) Identical alternative requirements previously approved by the
Administrator in another local agency within the same State, if
previously noticed that the alternative requirements would be applicable
in the jurisdiction seeking approval under this section.
[65 FR 55840, Sept. 14, 2000]
Sec. 63.93 Approval of State requirements that substitute
for a section 112 rule.
Under this section a State may seek approval of State requirements
which differ from a Federal section 112 rule for which they would
substitute, such that the State requirements do not qualify for approval
under Sec. 63.92.
(a) Approval process. (1) After receiving a complete request for
approval under this section and making a preliminary determination on
its equivalence, the Administrator will seek public comment on the
State's request for a minimum of 30 days through a Federal Register
notice. The Administrator will require that comments be submitted
concurrently to the State.
[[Page 127]]
(2) If, after review of public comments and any State responses to
comments submitted to the Administrator, the Administrator finds that
the criteria of this section and the criteria of Sec. 63.91 are met,
the Administrator will approve the State requirements under this
section, publish the approved requirements in the Federal Register, and
incorporate them directly or by reference, in the appropriate subpart of
part 63. Requirements approved under Sec. 63.95 will be incorporated
pursuant to requirements under part 68 of this chapter.
(3) If the Administrator finds that any of the requirements of this
section or Sec. 63.91 have not been met, the Administrator may
partially approve or disapprove the State requirements. For any partial
approvals or disapprovals, the Administrator will provide the State with
the basis for the partial approval or disapproval and what actions that
State can take to make the requirements approvable.
(4) Requirements submitted for approval under this section shall
include either: State rules, title V permits, title V general permits,
Federal new source review permits, board and administrative orders,
permits issued pursuant to permit templates, or State operating permits.
Permits must already be issued to be used under this section.
(5) If the State uses a permit as the basis of alternative
requirements under this section, the relevant permit terms and
conditions must remain applicable to the source even if it takes steps
that would otherwise release it from an obligation to have a permit.
(6) Within 180 days of receiving a complete request for approval
under this section, the Administrator will either approve, partially
approve, or disapprove the State request.
(b) Criteria for approval. Any request for approval under this
section shall meet all of the criteria of this section and Sec. 63.91
before approval. The State shall provide the Administrator with detailed
documentation that the State requirements contain or demonstrate:
(1) Applicability criteria that are no less stringent than those in
the respective Federal rule;
(2) Levels of control (including associated performance test
methods) and compliance and enforcement measures that result in emission
reductions from each affected source or accidental release prevention
program requirements for each affected source that are no less stringent
than would result from the otherwise applicable Federal rule;
(3) A compliance schedule that requires each affected source to be
in compliance within a time frame consistent with the deadlines
established in the otherwise applicable Federal rule; and
(4) At a minimum, the approved State requirements must include the
following compliance and enforcement measures. (For requirements
addressing the accidental release prevention program, minimum compliance
and enforcement provisions are described in Sec. 63.95.)
(i) The approved requirements must include monitoring or another
method for determining compliance.
(ii) If a standard in the approved rule is not instantaneous, a
maximum averaging time must be established.
(iii) The requirements must establish an obligation to periodically
monitor for compliance using the monitoring or another method
established in paragraph (b)(4)(i) of this section sufficient to yield
reliable data that are representative of the source's compliance status.
[65 FR 55841, Sept. 14, 2000]
Sec. 63.94 Approval of State permit terms and conditions that substitute
for a section 112 rule.
Under this section a State may seek approval of State permit terms
and conditions to be implemented and enforced in lieu of specified
existing and future Federal section 112 rules, emission standards, or
requirements promulgated under section 112, for those affected sources
permitted by the State under part 70 of this chapter. The State may not
seek approval under this section for permit terms and conditions that
implement and enforce part 68 requirements.
(a) Up-front approval process. (1) A State must submit a request
that meets the requirements of paragraph (b) of this section. After
receiving a
[[Page 128]]
complete request for approval of a State program under this section and
making a preliminary determination of equivalence, the Administrator
will seek public comment for 21 days through a Federal Register notice.
The Administrator will require that comments be submitted concurrently
to the State.
(2) If, after review of all public comments, and State responses to
comments submitted to the Administrator, the Administrator finds that
the criteria of paragraph (b) of this section and the criteria of Sec.
63.91 are met, the Administrator will approve the State program. The
approved program will be published in the Federal Register and
incorporated directly or by reference in the appropriate subpart of part
63.
(3) If the Administrator finds that any of the criteria of paragraph
(b) of this section or Sec. 63.91 have not been met, the Administrator
will partially approve or disapprove the State program. For any partial
approvals or disapprovals, the Administrator will provide the State with
the basis for the partial approval or disapproval and what action the
State can take to make the programs approvable.
(4) Within 90 days of receiving a complete request for approval
under this section, the Administrator will either approve, partially
approve, or disapprove the State request.
(b) Criteria for up-front approval. Any request for program approval
under this section shall meet all of the criteria of this paragraph and
Sec. 63.91 before approval. The State shall provide the Administrator
with:
(1)(i) To the extent possible, an identification of all specific
sources in source categories listed pursuant to subsection 112(c) for
which the State is seeking authority to implement and enforce
alternative requirements under this section;
(ii) If the identified sources in any source category comprise a
subset of the sources in that category within the State's jurisdiction,
the State shall request delegation for the remainder of the sources in
that category that are required to be permitted by the State under part
70 of this chapter. The State shall request delegation for the remainder
of the sources in that category under another section of this subpart.
(iii) Prior to submitting a request for one or more sources within a
source category, the State shall consult with their EPA Regional Office
regarding the number of sources in a category eligible for submittal
under this option. Based on the Regional Office's decision, the State
shall limit the number of sources for which it submits permit
requirements.
(2) To the extent possible, an identification of all existing and
future section 112 emission standards for which the State is seeking
authority under this section to implement and enforce alternative
requirements.
(3) If, after approval of the initial list of source categories
identified in paragraph (b)(2) of this section, the State adds source
categories for approval under this option, the State shall submit an
addendum to the up-front approval submission, and identify the addition
to the lists. The Administrator will follow the process outlined in
paragraph (a) of this section for up-front approval.
(4) A one-time demonstration that the State has an approved title V
operating permit program and that the program permits the affected
sources.
(c) Approval process for alternative requirements. (1) After
promulgation of a Federal section 112 rule, emission standard, or
requirement for which the State has up-front approval to implement and
enforce alternative requirements in the form of title V permit terms and
conditions, the State shall provide the Administrator with pre-draft
title V permit terms and conditions that are sufficient, in the
Administrator's judgement, to allow the Administrator to determine
equivalency. The permit terms and conditions shall reflect all of the
requirements of the otherwise applicable Federal section 112 rule,
emission standard, or requirement.
(2) [Reserved]
(3) If, the Administrator receives a complete request and finds the
pre-draft title V permit terms and conditions submitted by the State
meet the criteria of paragraph (d), the Administrator will approve the
State's alternative requirements (by approving the
[[Page 129]]
pre-draft permit terms and conditions) and notify the State in writing
of the approval.
(4) The Administrator may approve the State's alternative
requirements on the condition that the State makes certain changes to
the pre-draft title V permit terms and conditions and includes the
changes in the complete pre-draft, proposed, and final title V permits
for the affected sources. If the Administrator approves the alternative
requirements on the condition that the State makes certain changes to
them, the State shall make those changes or the alternative requirements
will not be federally enforceable when they are included in the final
permit, even if the Administrator does not object to the proposed
permit. Until the Administrator affirmatively approves the State's
alternative requirements (by approving the pre-draft permit terms and
conditions) under this paragraph, and those requirements (permit terms)
are incorporated into the final title V permit for any affected source,
the otherwise applicable Federal emission standard(s) remain the
federally enforceable and applicable requirements for that source.
(5) If, after evaluating the pre-draft title V permit terms and
conditions that were submitted by the State, the Administrator finds
that the criteria of paragraph (d) of this section have not been met,
the Administrator will disapprove the State's alternative requirements
and notify the State in writing of the disapproval. In the notice of
disapproval, the Administrator will specify the deficient or
nonapprovable elements of the State's alternative requirements.
(6) Within 90 days of receiving a complete request for approval
under this paragraph, the Administrator will either approve, partially
approve, or disapprove the State's alternative requirements.
(7) Nothing in this section precludes the State from submitting
alternative requirements in the form of title V permit terms and
conditions or title V general permit terms and conditions for approval
under this paragraph at the same time the State submits its program to
the Administrator for up-front approval under paragraph (a) of this
section, provided that the Federal emission standards for which the
State submits alternative requirements are promulgated at the time of
the State's submittal. If the Administrator finds that the criteria of
Sec. 63.91 and the criteria of paragraphs (b) and (d) of this section
are met, the Administrator will approve both the State program and the
permit terms and conditions within 90 days of receiving a complete
request for approval.
(d) Approval criteria for alternative requirements. Any request for
approval under this paragraph shall meet the following criteria. Taken
together, the criteria in this paragraph describe the minimum contents
of a State's equivalency demonstration for a promulgated Federal section
112 rule, emission standard, or requirement. To be approvable, the State
submittal must contain sufficient detail to allow the Administrator to
make a determination of equivalency between the State's alternative
requirements and the Federal requirements. Each submittal of alternative
requirements in the form of pre-draft permit terms and conditions for an
affected source shall:
(1) Identify the specific, practicably enforceable terms and
conditions with which the source would be required to comply upon
issuance, renewal, or revision of the title V permit. The State shall
submit permit terms and conditions that reflect all of the requirements
of the otherwise applicable Federal section 112 rule, emission standard,
or requirement. The State shall identify for the Administrator the
specific permit terms and conditions that contain alternative
requirements.
(2) Identify specifically how the alternative requirements in the
form of permit terms and conditions are the same as or differ from the
requirements in the otherwise applicable Federal section 112 rule,
emission standard, or requirement (including any applicable requirements
in subpart A or other subparts or appendices). The State shall provide
this identification in a side-by-side comparison of the State's
requirements in the form of permit terms and conditions and the
requirements of the Federal section 112 rule, emission standard, or
requirement.
[[Page 130]]
(3) The State shall provide the Administrator with detailed
documentation that demonstrates that the alternative requirements meet
the criteria specified in Sec. 63.93(b), i.e., that the alternative
requirements are at least as stringent as the otherwise applicable
Federal requirements.
(e) Incorporation of permit terms and conditions into title V
permits. (1) After approval of the State's alternative requirements
under this section, the State shall incorporate the approved permit
terms and conditions into title V permits for the affected sources. The
State shall issue or revise the title V permits according to the
provisions contained in Sec. 70.7 of this chapter. The alternative
permit terms and conditions may substitute for the Federal requirements
once they are contained in a valid title V permit. If the State does not
write the alternative conditions, exactly as approved, into the permit,
EPA may reopen the permit for cause per Sec. 70.7(g) of this chapter,
and the delegation may not occur.
(2) In the notice of pre-draft permit availability, and in each pre-
draft, proposed, and final permit, the State shall indicate prominently
that the permit contains alternative section 112 requirements. In the
notice of pre-draft permit availability, the State shall specifically
solicit public comment on the alternative requirements. In addition, the
State shall attach all documents supporting the approved equivalency
determination for those alternative requirements to each pre-draft,
proposed, and final permit.
[65 FR 55841, Sept. 14, 2000]
Sec. 63.95 Additional approval criteria for accidental release
prevention programs.
(a) A State submission for approval of a part 68 program must meet
the criteria and be in accordance with the procedures of this section,
Sec. 63.91, and, where appropriate, either Sec. 63.92 or Sec. 63.93.
(b) The State part 68 program application shall contain the
following elements consistent with the procedures in Sec. 63.91 and,
where appropriate, either Sec. 63.92 or Sec. 63.93 of this subpart,
for at least the chemicals listed in part 68 subpart F (``federally-
listed chemicals'') that an approvable State Accidental Release
Prevention program is regulating:
(1)(i) A demonstration of the State's authority and resources to
implement and enforce regulations that are no less stringent than the
regulations of part 68, subparts A through G and Sec. 68.200 of this
chapter; and
(ii) A requirement that any source subject to the State's part 68
program submit a Risk Management Plan (RMP) that reports at least the
same information in the same format as required under part 68, subpart G
of this chapter.
(2) A State's RMP program may require reporting of information not
required by the Federal program, and these requirements (like any other
additional State requirements) will become federally enforceable upon
approval. The extent to which EPA will be able to help a State collect
and report additional information through EPA's electronic RMP
submission system will be determined on a case-by-case basis.
(3) Procedures for reviewing risk management plans and providing
technical assistance to stationary sources, including small businesses.
(4) A demonstration of the State's authority to enforce all part 68
requirements must be made, including an auditing strategy that complies
with Sec. 68.220 of this chapter.
(c) A State may request approval for a program that covers all of
the federally-listed chemicals (a ``complete program'') or a program
covering less than all of the federally-listed chemicals (a ``partial
program'') as long as the State takes delegation of the full part 68
program for the federally-listed chemicals it regulates.
[65 FR 55843, Sept. 14, 2000]
Sec. 63.96 Review and withdrawal of approval.
(a) Submission of information for review of approval. (1) The
Administrator may at any time request any of the following information
to review the adequacy of implementation and enforcement of an approved
rule or program and the State shall provide that information within 45
days of the Administrator's request:
[[Page 131]]
(i) Copies of any State statutes, rules, regulations or other
requirements that have amended, repealed or revised the approved State
rule or program since approval or since the immediately previous EPA
review;
(ii) Information to demonstrate adequate State enforcement and
compliance monitoring activities with respect to all approved State
rules and with all section 112 rules, emission standards or
requirements;
(iii) Information to demonstrate adequate funding, staff, and other
resources to implement and enforce the State's approved rule or program;
(iv) A schedule for implementing the State's approved rule or
program that assures compliance with all section 112 rules and
requirements that the EPA has promulgated since approval or since the
immediately previous EPA review,
(v) A list of part 70 or other permits issued, amended, revised, or
revoked since approval or since immediately previous EPA review, for
sources subject to a State rule or program approved under this subpart.
(vi) A summary of enforcement actions by the State regarding
violations of section 112 requirements, including but not limited to
administrative orders and judicial and administrative complaints and
settlements.
(2) Upon request by the Administrator, the State shall demonstrate
that each State rule, emission standard or requirement applied to an
individual source is no less stringent as applied than the otherwise
applicable Federal rule, emission standard or requirement.
(b) Withdrawal of approval of a state rule or program. (1) If the
Administrator has reason to believe that a State is not adequately
implementing or enforcing an approved rule or program according to the
criteria of this section or that an approved rule or program is not as
stringent as the otherwise applicable Federal rule, emission standard or
requirements, the Administrator will so inform the State in writing and
will identify the reasons why the Administrator believes that the
State's rule or program is not adequate. The State shall then initiate
action to correct the deficiencies identified by the Administrator and
shall inform the Administrator of the actions it has initiated and
completed. If the Administrator determines that the State's actions are
not adequate to correct the deficiencies, the Administrator will notify
the State that the Administrator intends to withdraw approval and will
hold a public hearing and seek public comment on the proposed withdrawal
of approval. The Administrator will require that comments be submitted
concurrently to the State. Upon notification of the intent to withdraw,
the State will notify all sources subject to the relevant approved rule
or program that withdrawal proceedings have been initiated.
(2) Based on any public comment received and any response to that
comment by the State, the Administrator will notify the State of any
changes in identified deficiencies or actions needed to correct
identified deficiencies. If the State does not correct the identified
deficiencies within 90 days after receiving revised notice of
deficiencies, the Administrator shall withdraw approval of the State's
rule or program upon a determination that:
(i) The State no longer has adequate authorities to assure
compliance or re-sources to implement and enforce the approved rule or
program, or
(ii) The State is not adequately implementing or enforcing the
approved rule or program, or
(iii) An approved rule or program is not as stringent as the
otherwise applicable Federal rule, emission standard or requirement.
(3) The Administrator may withdraw approval for part of a rule, for
a rule, for part of a program, or for an entire program.
(4) Any State rule, program or portion of a State rule or program
for which approval is withdrawn is no longer Federally enforceable. The
Federal rule, emission standard or requirement that would have been
applicable in the absence of approval under this will be the federally
enforceable rule, emission standard or requirement.
(i) Upon withdrawal of approval, the Administrator will publish an
expeditious schedule for sources subject to the previously approved
State rule or program to come into compliance with
[[Page 132]]
applicable Federal requirements. Such schedule shall include interim
emission limits where appropriate. During this transition, sources must
be operated in a manner consistent with good air pollution control
practices for minimizing emissions.
(ii) Upon withdrawal, the State shall reopen, under the provisions
of Sec. 70.7(f) of this chapter, the part 70 permit of each source
subject to the previously approved rules or programs in order to assure
compliance through the permit with the applicable requirements for each
source.
(iii) If the Administrator withdraws approval of State rules
applicable to sources that are not subject to part 70 permits, the
applicable State rules are no longer Federally enforceable.
(iv) If the Administrator withdraws approval of a portion of a State
rule or program, other approved portions of the State rule or program
that are not withdrawn shall remain in effect.
(v) Any applicable Federal emission standard or requirement shall
remain enforceable by the EPA as specified in section 112(l)(7) of the
Act.
(5) If a rule approved under Sec. 63.93 is withdrawn under the
provisions of Sec. 63.96(b)(2) (i) or (ii), and, at the time of
withdrawal, the Administrator finds the rule to be no less stringent
than the otherwise applicable Federal requirement, the Administrator
will grant equivalency to the previously approved State rule under the
appropriate provisions of this part.
(6) A State may submit a new rule, program or portion of a rule or
program for approval after the Administrator has withdrawn approval of
the State's rule, program or portion of a rule or program. The
Administrator will determine whether the new rule or program or portion
of a rule or program is approvable according to the criteria and
procedures of Sec. 63.91 and either of Sec. 63.92, Sec. 63.93 or
Sec. 63.94.
(7) A State may voluntarily withdraw from an approved State rule,
program or portion of a rule or program by notifying the EPA and all
affected sources subject to the rule or program and providing notice and
opportunity for comment to the public within the State.
(i) Upon voluntary withdrawal by a State, the Administrator will
publish a timetable for sources subject to the previously approved State
rule or program to come into compliance with applicable Federal
requirements.
(ii) Upon voluntary withdrawal, the State must reopen and revise the
part 70 permits of all sources affected by the withdrawal as provided
for in this section and Sec. 70.7(f), and the Federal rule, emission
standard, or requirement that would have been applicable in the absence
of approval under this subpart will become the applicable requirement
for the source.
(iii) Any applicable Federal section 112 rule, emission standard or
requirement shall remain enforceable by the EPA as specified in section
112(l)(7) of the Act.
(iv) Voluntary withdrawal shall not be effective sooner than 180
days after the State notifies the EPA of its intent to voluntarily
withdraw.
[65 FR 55843, Sept. 14, 2000]
Sec. 63.97 Approval of a State program that substitutes
for section 112 requirements.
Under this section, a State may seek approval of a State program to
be implemented and enforced in lieu of specified existing or future
Federal emission standards or requirements promulgated under section
112. A State may not seek approval under this section for a program that
implements and enforces part 68 requirements.
(a) Up-front approval process. (1) After receiving a complete
request for approval of a State program submitted under paragraph (b)(1)
or (b)(2) of this section and making a preliminary determination on
whether to approve it, the Administrator will seek public comment for 21
days through a Federal Register notice. At its discretion, the State may
include in this submittal a request for approval of specific alternative
requirements under paragraph (b)(3) of this section.
(2) [Reserved]
(3) The Administrator will require that comments be submitted
concurrently to the State.
(4) If, after review of all public comments and State responses to
comments submitted to the Administrator, the Administrator finds that
the criteria of paragraph (b) of this section
[[Page 133]]
and the criteria of Sec. 63.91 are met, the Administrator will approve
or partially approve the State program. The approved State program will
be published in the Federal Register and incorporated, directly or by
reference, in the appropriate subpart of part 63.
(5) If the Administrator finds that any of the criteria of paragraph
(b) of this section or Sec. 63.91 have not been met, the Administrator
will partially approve or disapprove the State program.
(6) The Administrator will either approve, partially approve, or
disapprove the State request:
(i) Within 90 days after receipt of a complete request for approval
of a State program submitted under paragraph (b)(1) or (b)(2) of this
section; or
(ii) Within 180 days after receipt of a complete request for
approval of a State program submitted under paragraphs (b)(1) or (b)(2)
and paragraph (b)(3) of this section.
(b) Criteria for up-front approval. Any request for program approval
under this section shall meet all of the criteria of this paragraph and
Sec. 63.91 before approval.
(1) For every request for program approval under this section, the
State shall provide the Administrator, to the extent possible, with an
identification of the initial specific source categories listed pursuant
to section 112(c) and an identification of all existing and future
section 112 emission standards or other requirements for which the State
is seeking authority to implement and enforce alternative requirements
under this section.
(2) If, after approval of the initial list of specific source
categories identified in paragraph (b)(1) of this section, the State
adds source categories for approval under this option, the State shall
submit an addendum to the approval submission, and identify the addition
to the list.
(3) In addition, the State may provide the Administrator with one or
more of the following program elements for approval under this
paragraph:
(i) Alternative requirements in State rules, regulations, or general
permits (or other enforceable mechanisms) that apply generically to one
or more categories of sources and for which the State seeks approval to
implement and enforce in lieu of specific existing Federal section 112
emission standards or requirements. The Administrator may approve or
disapprove the alternative requirements in these rules, regulations, or
permits when approving or disapproving the State's up-front submittal
under this paragraph. After approval of the alternative generic rules,
regulations or general permits, and after new Federal emission standards
or requirements are promulgated, the State may extend the applicability
of approved generic alternative requirements to additional source
categories by repeating the approval process specified in paragraph (a)
of this section. To be approvable, any request for approval of generic
alternative requirements during the up-front approval process shall meet
the criteria in paragraph (d) of this section.
(ii) A description of the mechanisms that are enforceable as a
matter of State law that the State will use to implement and enforce
alternative requirements for area sources. The mechanisms that may be
approved under this paragraph include title V permits, title V general
permits, Federal new source review permits, board and administrative
orders, permits issued pursuant to permit templates, state permits, and
State rules that apply to categories of sources. The State shall
demonstrate to the Administrator that the State has adequate resources
and authorities to implement and enforce alternative section 112
requirements using the State mechanisms.
(c) Approval process for alternative requirements. (1) After
promulgation of a Federal emission standard or requirement for which the
State has program approval under this section to implement and enforce
alternative requirements, the State shall provide the Administrator with
alternative requirements that are sufficient, in the Administrator's
judgement, to allow the Administrator to determine equivalency under
paragraph (d) of this section. The alternative requirements shall
reflect all of the requirements of the otherwise applicable Federal
section 112 rule, emission standard, or requirement, including any
alternative requirements that the State is seeking
[[Page 134]]
to implement and enforce. Alternative requirements submitted for
approval under this paragraph shall be contained in rules, regulations,
general permits, or other mechanisms that apply to and are enforceable
under State law for categories of sources. State policies are not
approvable under this section unless they are incorporated into
specific, enforceable, alternative requirements in rules, permits, or
other mechanisms that apply to categories of sources.
(2) [Reserved]
(3) After receiving a complete request for approval under this
section and making a preliminary determination on its equivalence, the
Administrator will seek public comment for a minimum of 21 days through
a Federal Register notice. The Administrator will require that comments
be submitted concurrently to the State.
(4) If, after review of public comments and any State responses to
comments submitted to the Administrator, the Administrator finds that
the criteria of paragraph (d) of this section and the criteria of Sec.
63.91 are met, the Administrator will approve the State's alternative
requirements. The approved alternative requirements will be published in
the Federal Register and incorporated, directly or by reference, in the
appropriate subpart of part 63.
(5) If the Administrator finds that any of the requirements of
paragraph (d) of this section or Sec. 63.91 have not been met, the
Administrator will partially approve or disapprove the State's
alternative requirements. For any partial approvals or disapprovals, the
Administrator will provide the State with the basis for the partial
approval or disapproval and what action the State can take to make the
alternative requirements approvable.
(6) Within 180 days of receiving a complete request for approval
under this paragraph, the Administrator will either approve, partially
approve, or disapprove the State request.
(7) Nothing in this section precludes the State from submitting
alternative requirements for approval under this paragraph at the same
time the State submits its program to the Administrator for up-front
approval under paragraph (a) of this section, provided that the Federal
rules, emission standards, or requirements for which the State submits
alternative requirements are promulgated at the time of the State's
submittal. If the Administrator finds that the criteria of Sec. 63.91
and the criteria of paragraphs (b) and (d) of this section are met, the
Administrator will approve both the State program and the alternative
requirements within 180 days of receiving a complete request for
approval. Alternatively, following up-front approval, the State may
submit alternative requirements for approval under this paragraph at any
time after promulgation of the Federal emission standards or
requirements.
(d) Approval criteria for alternative requirements. Any request for
approval under this paragraph shall meet the following criteria. Taken
together, the criteria in this paragraph describe the minimum contents
of a State's equivalency demonstration for a promulgated Federal section
112 rule, emission standard, or requirement. To be approvable, the State
submittal must contain sufficient detail to allow the Administrator to
make a determination of equivalency between the State's alternative
requirements and the Federal requirements. Each submittal of alternative
requirements for a category of sources shall:
(1) Include copies of all State rules, regulations, permits, or
other enforceable mechanisms that contain the alternative requirements
for which the State is seeking approval. These documents shall also
contain requirements that reflect all of the requirements of the
otherwise applicable Federal section 112 rules, emission standards or
requirements for which the State is not submitting alternatives. The
State shall identify for the Administrator the specific requirements
with which sources in a source category are required to comply,
including the specific alternative requirements.
(2) Identify specifically how the alternative requirements are the
same as or differ from the requirements in the otherwise applicable
Federal rule, emission standards, or requirements (including any
applicable requirements
[[Page 135]]
in subpart A or other subparts or appendices). The State shall provide
this identification in a side-by-side comparison of the State's
requirements and the requirements of the Federal rule, emission
standards, or requirements.
(3) The State shall provide the Administrator with detailed
documentation that demonstrates the State's belief that the alternative
requirements meet the criteria specified in Sec. 63.93(b) of this
subpart, i.e., that the alternative requirements are at least as
stringent as the otherwise applicable Federal requirements.

\1\ State program approved on June 26, 1995. Delegation table last updated on February 23, 2009.
(ii) South Carolina Department of Health and Environmental Control
(SC DHEC) may implement and enforce alternative requirements in the form
of title V permit terms and conditions for International Paper
Georgetown Mill, Georgetown, South Carolina, for subpart S of this
part--National Emission Standards for Hazardous Air Pollutants from the
Pulp and Paper Industry. This action is contingent upon SC DHEC
including, in title V permits, terms and conditions that are no less
stringent than the Federal standard. In addition, the requirement
applicable to the source remains the Federal section 112 requirement
until EPA has approved the alternative permit terms and conditions and
the final title V permit is issued.
(42) [Reserved]
(43) Tennessee. (i) The Tennessee Department of Environment and
Conservation (TDEC) has ``up-front'' approval to implement an
Equivalency by Permit (EBP) program under which TDEC may establish and
enforce alternative requirements for the Ellison Surface Technologies,
Inc. facility located in Morgan County, Tennessee (Ellison) in lieu of
those of the National Emissions Standard for Hazardous Air Pollutants
(NESHAP) for Plating and Polishing Operations at 40 CFR part 63, subpart
WWWWWW, ``National Emission Standards for Hazardous Air Pollutants: Area
Source Standards for Plating and Polishing Operations.'' TDEC may only
establish alternative requirements for Ellison that are at least as
stringent as the otherwise applicable Federal requirements. TDEC must,
in order to establish alternative requirements for Ellison under its
EPA-approved EBP program: submit to the EPA for review pre-draft title V
permit terms specifying alternative requirements that meet the criteria
of 40 CFR 63.94(d), including the criterion that the alternative
requirements are at least as stringent as the otherwise applicable
[[Page 181]]
Federal requirements; obtain the EPA's written approval of the
alternative pre-draft title V permit requirements; and issue a title V
permit for Ellison that contains the approved alternative requirements.
Until the EPA has approved the alternative permit terms and conditions
and TDEC has issued a final title V permit incorporating them, Ellison
will remain subject to the Federal NESHAP requirements found at 40 CFR
part 63, subpart WWWWWW.
(ii) Reserved.

certifies, in a notification to the appropriate EPA Regional Office, not
later than May 14, 1996, that the plant site at which the chemical
manufacturing processing unit is located emits, and will continue to
emit, during any 12-month period, less than 10 tons per year of any
individual hazardous air pollutants (HAP), and less than 25 tons per
year of any combination of HAP.
(i) If such a determination is based on limitations and conditions
that are not federally enforceable (as defined in subpart A of this
part), the owner or operator shall document the basis for the
determination as specified in paragraphs (b)(4)(i)(A) through
(b)(4)(i)(C) and comply with the recordkeeping requirement in 63.103(f).
(A) The owner or operator shall identify all HAP emission points at
the plant site, including those emission points subject to and emission
points not subject to subparts F, G, and H;
(B) The owner or operator shall calculate the amount of annual HAP
[[Page 189]]
emissions released from each emission point at the plant site, using
acceptable measurement or estimating techniques for maximum expected
operating conditions at the plant site. Examples of estimating
procedures that are considered acceptable include the calculation
procedures in Sec. 63.150 of subpart G, the early reduction
demonstration procedures specified in Sec. Sec. 63.74 (c)(2), (c)(3),
(d)(2), (d)(3), and (g), or accepted engineering practices. If the total
annual HAP emissions for the plant site are annually reported under

equally based on operating time, then the product with the greatest
annual production on a mass basis shall represent the primary product of
the flexible operation unit.
(ii) The determination of applicability of this subpart to chemical
manufacturing process units that are designed and operated as flexible
operation units shall be reported as part of an operating permit
application or as otherwise specified by the permitting authority.
(4) Notwithstanding the provisions of paragraph (d)(3) of this
section, for chemical manufacturing process units
[[Page 190]]
that are designed and operated as flexible operation units producing a
chemical listed in paragraph (b)(1)(ii) of this section, the primary
product shall be determined for existing sources based on the expected
utilization for the five years following May 12, 1998 and for new
sources based on the expected utilization for the first five years after
initial start-up.
(i) The predominant use of the flexible operation unit shall be
determined according to paragraphs (d)(3)(i)(A) and (d)(3)(i)(B) of this
section. If the predominant use is to produce one of the chemicals
listed in paragraph (b)(1)(ii) of this section, then the flexible
operation unit shall be subject to the provisions of this subpart and
subparts G and H of this part.
(ii) The determination of applicability of this subpart to chemical
manufacturing process units that are designed and operated as flexible

the applicability of this subpart F and subpart G of this part shall be
determined according to the provisions
[[Page 192]]
in paragraphs (g)(3)(i) through (g)(3)(iv) of this section.
(i) The storage vessel may only be assigned to a chemical
manufacturing 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 chemical manufacturing process unit,
an intervening storage vessel means a storage vessel connected by hard-
piping to the chemical manufacturing process unit and to the storage
vessel in the tank farm so that product or raw material entering or
leaving the chemical manufacturing 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 chemical manufacturing process unit at the major
source that meets the criteria of paragraph (g)(3)(i) of this section
with respect to a storage vessel, this subpart F and subpart G of this
part do not apply to the storage vessel.
(iii) If there is only one chemical manufacturing process unit at
the major source that meets the criteria of paragraph (g)(3)(i) of this
section with respect to a storage vessel, the storage vessel shall be
assigned to that chemical manufacturing process unit. Applicability of
this subpart F and subpart G to this part to the storage vessel shall
then be determined according to the provisions of paragraph (b) of this
section.
(iv) If there are two or more chemical manufacturing process units
at the major source that meet the criteria of paragraph (g)(3)(i) of
this section with respect to a storage vessel, the storage vessel shall
be assigned to one of those chemical manufacturing process units
according to the provisions of paragraph (g)(2) of this section. The
predominant use shall be determined among only those chemical
manufacturing process units that meet the criteria of paragraph
(g)(3)(i) of this section. Applicability of this subpart F and subpart G
of this part to the storage vessel shall then be determined according to
the provisions of paragraph (b) of this section.
(4) If the storage vessel begins receiving material from (or sending
material to) another chemical manufacturing process unit, or ceases to
receive material from (or send material to) a chemical manufacturing
process unit, or if the applicability of this subpart F and subpart G of
this part to a storage vessel has been determined according to the
provisions of paragraphs (g)(2)(i) and (g)(2)(ii) of this section and
there is a change so that the predominant use may reasonably have
changed, the owner or operator shall reevaluate the applicability of
this subpart to the storage vessel.
(h) The owner or operator shall follow the procedures specified in
paragraphs (h)(1) and (h)(2) of this section to determine whether the
arms and hoses in a loading rack are part of the source to which this

paragraphs (f)(9) and (f)(10) of this section, then the loading rack is
considered a transfer rack (as defined in Sec. 63.101 of this subpart)
and is part of the source to which this subpart applies.
(ii) If the chemical manufacturing process unit is not subject to
this subpart according to the criteria specified in paragraph (b) of
this section, then the loading rack is not considered a transfer rack
(as defined in Sec. 63.101 of this subpart) and is not a part of the
source to which this subpart applies.
(2) If a loading rack is shared among chemical manufacturing process
units, then the applicability of this subpart F and subpart G of this
part shall be determined at each loading arm or loading hose according
to the provisions in paragraphs (h)(2)(i) through (h)(2)(iv) of this
section.
(i) Each loading arm or loading hose that is dedicated to the
transfer of liquid organic hazardous air pollutants listed in table 2 of
this subpart from a chemical manufacturing process unit to which this
subpart applies is part of that chemical manufacturing process
[[Page 193]]
unit and is part of the source to which this subpart applies unless the
loading arm or loading hose meets the criteria specified in paragraphs

owner or operator may assign the loading arm or loading hose to any of
the chemical manufacturing process units subject to this subpart.
(iv) If the predominant use of a loading arm or loading hose varies
from year to year, then the applicability of this subpart shall be
determined according to the criteria in paragraphs (h)(2)(iv)(A) and
(h)(2)(iv)(B) of this section, as applicable. This determination shall
be reported as part of an operating permit application or as otherwise
specified by the permitting authority.
(A) For chemical manufacturing process units that produce one or
more of the chemicals listed in table 1 of this subpart and meet the
criteria in paragraphs (b)(2) and (b)(3) of this section, the
applicability shall be based on the utilization that occurred during the

Sec. 63.102 General standards.
(a) Owners and operators of sources subject to this subpart shall
comply with the requirements of subparts G and H of this part.
(1) The provisions set forth in this subpart F and subpart G of this
part shall apply at all times except during periods of start-up or
shutdown (as defined in Sec. 63.101 of this subpart), malfunction, or
non-operation of the chemical manufacturing process unit (or specific
portion thereof) resulting in cessation of the emissions to which this
subpart F and subpart G of this part apply. However, if a start-up,
shutdown, malfunction or period of non-operation of one portion of a
chemical manufacturing process unit does not affect the ability of a
particular emission point to comply with the specific provisions to
which it is subject, then that emission point shall still be required to
comply with the applicable provisions of this subpart F and subpart G of
this part 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 in the chemical manufacturing process unit would still
be required to be controlled in accordance
[[Page 207]]
with Sec. 63.119 of subpart G of the part. Similarly, the degassing of
a storage vessel would not affect the ability of a process vent to meet
the requirements of Sec. 63.113 of subpart G of this part.
(2) The provisions set forth in subpart H of this part shall apply
at all times except during periods of start-up or shutdown, as defined
in Sec. 63.101(b) of this subpart, malfunction, process unit shutdown
(as defined in Sec. 63.161 of subpart H of this part), or non-operation
of the chemical manufacturing process unit (or specific portion thereof)
in which the lines are drained and depressurized resulting in cessation
of the emissions to which subpart H of this part applies.
(3) The owner or operator shall not shut down items of equipment
that are required or utilized for compliance with the provisions of this
subpart F, subpart G or H of this part 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 F, subpart G or H of this part 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 start-up, shutdown, or
malfunction of the chemical manufacturing process unit or portion
thereof.
(4) During start-ups, shutdowns, and malfunctions when the
requirements of this subpart F, subparts G and/or H of this part do not
apply pursuant to paragraphs (a)(1) through (a)(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. The general duty to minimize emissions during a period of
startup, shutdown, or malfunction does not require the owner or operator
to achieve emission levels that would be required by the applicable
standard at other times if this is not consistent with safety and good
air pollution control practices, nor does it require the owner or
operator to make any further efforts to reduce emissions if levels
required by the applicable standard have been achieved. Determination of
whether such operation and maintenance procedures are being used will be
based on information available to the Administrator which may include,
but is not limited to, monitoring results, review of operation and
maintenance procedures (including the startup, shutdown, and malfunction
plan required in Sec. 63.6(e)(3)), review of operation and maintenance
records, and inspection of the source. The measures to be taken 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.
(b) If, in the judgment of the Administrator, an alternative means
of emission limitation will achieve a reduction in organic HAP emissions
at least equivalent to the reduction in organic HAP emissions from that
source achieved under any design, equipment, work practice, or
operational standards in subpart G or H of this part, the Administrator
will publish in the Federal Register a notice permitting the use of the
alternative means for purposes of compliance with that requirement.
(1) The notice may condition the permission on requirements related
to the operation and maintenance of the alternative means.
(2) Any notice under paragraph (b) of this section shall be
published only after public notice and an opportunity for a hearing.
(3) Any person seeking permission to use an alternative means of
compliance under this section shall collect, verify, and submit to the
Administrator information showing that the alternative means achieves
equivalent emission reductions.
(c) Each owner or operator of a source subject to this subpart shall
obtain a permit under 40 CFR part 70 or part 71 from the appropriate
permitting authority by the date determined by 40 CFR part 70 or part
71, as appropriate.
(1) If the EPA has approved a State operating permit program under
40
[[Page 208]]
CFR Part 70, the permit shall be obtained from the State authority. If
the State operating permit program has not been approved, the source
shall apply to the EPA Regional Office.
(2) [Reserved]
(d) The requirements in subparts F, G, and H of this part are
Federally enforceable under section 112 of the Act on and after the
dates specified in Sec. 63.100(k) of this subpart.

Sec. 63.103 General compliance, reporting, and recordkeeping provisions.
(a) Table 3 of this subpart specifies the provisions of subpart A
that apply and those that do not apply to owners and operators of
sources subject to subparts F, G, and H of this part.
(b) Initial performance tests and initial compliance determinations
shall be required only as specified in subparts G and H of this part.
(1) Performance tests and compliance determinations shall be
conducted according to the schedule and procedures in Sec. 63.7(a) of
subpart A of this part and the applicable sections of subparts G and H
of this part.
(2) The owner or operator shall notify the Administrator of the
intention to conduct a performance test at least 30 calendar days before
the performance test is scheduled to allow the Administrator the
opportunity to have an observer present during the test.
(3) Performance tests shall be conducted according to the provisions
of Sec. 63.7(e) of subpart A of this part, except that performance
tests shall be conducted at maximum representative operating conditions
for the process. During the performance test, an owner or operator may
operate the control or recovery device at maximum or minimum
representative operating conditions for monitored control or recovery
device parameters, whichever results in lower emission reduction.
(4) Data shall be reduced in accordance with the EPA-approved
methods specified in the applicable subpart or, if other test methods
are used, the data and methods shall be validated according to the
protocol in Method 301 of appendix A of this part.
(5) Performance tests may be waived with approval of the
Administrator as specified in Sec. 63.7(h)(2) of subpart A of this
part. Owners or operators of sources subject to subparts F, G, and H of
this part who apply for a waiver of a performance test shall submit the
application by the dates specified in paragraph (b)(5)(i) of this
section rather than the dates specified in Sec. 63.7(h)(3) of subpart A
of this part.
(i) If a request is made for an extension of compliance under Sec.
63.151(a)(6) of subpart G or Sec. 63.6(i) of subpart A of this part,
the application for a waiver of an initial performance test shall
accompany the information required for the request for an extension of
compliance. If no extension of compliance is requested, the application
for a waiver of an initial performance test shall be submitted no later
than 90 calendar days before the Notification of Compliance Status
required in Sec. 63.152(b) of subpart G of this part is due to be
submitted.
(ii) Any application for a waiver of a performance test shall
include information justifying the owner or operator's request for a
waiver, such as the technical or economic infeasibility, or the
impracticality, of the source performing the required test.
(6) The owner or operator of a flexible operation unit shall conduct
all required compliance demonstrations during production of the primary
product. The owner or operator is not required to conduct compliance
demonstrations for operating conditions during production of a product
other than the primary product. Except as otherwise provided in this
subpart or in subpart G or subpart H of this part, as applicable, the
owner or operator shall operate each control device, recovery device,
and/or recapture device that is required or used for compliance, and
associated monitoring systems, without regard for whether the product
that is being produced is the primary product or a different product.
Except as otherwise provided in this subpart, subpart G and/or subpart H
of this part, as applicable, operation of a control device, recapture
device and/or recovery device required or used for compliance such that
the
[[Page 209]]
daily average of monitored parameter values is outside the parameter
range established pursuant to Sec. 63.152(b)(2), or such that the
monitoring data show operation inconsistent with the monitoring plan
established pursuant to Sec. 63.120(d)(2) or Sec. 63.181(g)(1)(iv),
shall constitute a violation of the required operating conditions.
(c) Each owner or operator of a source subject to subparts F, G, and
H of this part shall keep copies of all applicable reports and records
required by subparts F, G, and H of this part for at least 5 years;
except that, if subparts G or H require records to be maintained for a
time period different than 5 years, those records shall be maintained
for the time specified in subpart G or H of this part. If an owner or
operator submits copies of reports to the applicable EPA Regional
Office, the owner or operator is not required to maintain copies of
reports. If the EPA Regional Office has waived the requirement of Sec.
63.10(a)(4)(ii) for submittal of copies of reports, the owner or
operator is not required to maintain copies of reports.
(1) All applicable records shall be maintained in such a manner that
they can be readily accessed. The most recent 6 months of records shall
be retained on site or shall be accessible from a central location by
computer or other means that provides access within 2 hours after a
request. The remaining four and one-half years of records may be
retained offsite. Records may be maintained in hard copy or computer-
readable form including, but not limited to, on paper, microfilm,
computer, floppy disk, magnetic tape, or microfiche.
(2) The owner or operator subject to subparts F, G, and H of this
part shall keep the records specified in this paragraph, as well as
records specified in subparts G and H.
(i) Records of the occurrence and duration of each start-up,
shutdown, and malfunction of operation of process equipment or of air
pollution control equipment or continuous monitoring systems used to
comply with this subpart F, subpart G, or H of this part during which
excess emissions (as defined in Sec. 63.102(a)(4)) occur.
(ii) For each start-up, shutdown, and malfunction during which
excess emissions (as defined in Sec. 63.102(a)(4)) occur, records that
the procedures specified in the source's start-up, shutdown, and
malfunction plan were followed, and documentation of actions taken that
are not consistent with the plan. For example, if a start-up, shutdown,
and malfunction plan includes procedures for routing a control device to
a backup control device (e.g., the incinerator for a halogenated stream
could be routed to a flare during periods when the primary control
device is out of service), records must be kept of whether the plan was
followed. These records may take the form of a ``checklist,'' or other
form of recordkeeping that confirms conformance with the start-up,
shutdown, and malfunction plan for the event.
(iii) For continuous monitoring systems used to comply with subpart
G of this part, records documenting the completion of calibration checks
and maintenance of continuous monitoring systems that are specified in
the manufacturer's instructions or other written procedures that provide
adequate assurance that the equipment would reasonably be expected to
monitor accurately.
(3) Records of start-up, shutdown and malfunction and continuous
monitoring system calibration and maintenance are not required if they
pertain solely to Group 2 emission points, as defined in Sec. 63.111 of
subpart G of this part, that are not included in an emissions average.
(d) All reports required under subparts F, G, and H of this part
shall be sent to the Administrator at the addresses listed in Sec.
63.13 of subpart A of this part, except that requests for permission to
use an alternative means of compliance as provided for in Sec.
63.102(b) of this subpart and application for approval of a nominal
efficiency as provided for in Sec. 63.150 (i)(1) through (i)(6) of
subpart G of this part shall be submitted to the Director of the EPA
Office of Air Quality Planning and Standards rather than to the
Administrator or delegated authority.
(1) Wherever subpart A of this part specifies ``postmark'' dates,
submittals may be sent by methods other than the
[[Page 210]]
U.S. Mail (e.g., by fax or courier). Submittals shall be sent on or
before the specified date.
(2) If acceptable to both the Administrator and the owner or
operator of a source, reports may be submitted on electronic media.
(e) The owner or operator of a chemical manufacturing process unit
which meets the criteria of Sec. 63.100(b)(1) and Sec. 63.100(b)(3),
but not the criteria of Sec. 63.100(b)(2), shall comply with the
requirements of either paragraph (e)(1) or (e)(2) of this section.
(1) Retain information, data, and analysis used to determine that
the chemical manufacturing process unit does not use as a reactant or
manufacture as a product or co-product any organic hazardous air
pollutant. Examples of information that could document this 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
chemical manufacturing process unit does not use as a reactant or
manufacture as a product or co-product any organic hazardous air
pollutant.
(f) To qualify for the exemption specified in Sec. 63.100(b)(4) of
this subpart, the owner or operator shall maintain the documentation of
the information required pursuant to Sec. 63.100(b)(4)(i), and
documentation of any update of this information requested by the EPA
Regional Office, and shall provide the documentation to the EPA Regional
Office upon request. The EPA Regional Office will notify the owner or
operator, after reviewing such documentation, if the source does not
qualify for the exemption specified in Sec. 63.100(b)(4) of this
section. In such cases, compliance with subpart H shall be required no
later than 90 days after expiration of the applicable compliance date in
Sec. 63.100(k)(3), but in no event earlier than 90 days after the date
of such notification by the EPA Regional Office. Compliance with this
subpart F and subpart G of this part shall be no later than April 22,
1997, or as otherwise specified in Sec. 63.100(k)(2)(ii) of this
subpart, unless an extension has been granted by the EPA Regional Office
or permitting authority as provided in Sec. 63.6(i) of subpart A of
this part.
(g) An owner or operator who elects to use the compliance extension
provisions of Sec. 63.100(k)(6)(i) or (ii) shall submit a compliance
extension request to the appropriate EPA Regional Office no later than
45 days before the applicable compliance date in Sec. 63.100(k)(3), but
in no event is submittal required earlier than May 10, 1995. The request
shall contain the information specified in Sec. 63.100(k)(5)(iv) and
the reason compliance can not reasonably be achieved without a process
unit shutdown, as defined in 40 CFR 63.161 or without replacement of the
compressor or recasting of the distance piece.
(h) An owner or operator who elects to use the compliance extension
provisions of Sec. 63.100(k)(8) shall submit to the appropriate EPA
Regional Office a brief description of the process change, identify the
HAP eliminated, and the expected date of cessation of use or production
of HAP. The description shall be submitted no later than May 10, 1995,
or with the Notice of Compliance Status as required in Sec. 63.182(c)
of subpart H, whichever is later.

Sec. 63.104 Heat exchange system requirements.
(a) Unless one or more of the conditions specified in paragraphs
(a)(1) through (a)(6) of this section are met, owners and operators of
sources subject to this subpart shall monitor each heat exchange system
used to cool process equipment in a chemical manufacturing process unit
meeting the conditions of Sec. 63.100 (b)(1) through (b)(3) of this
subpart, except for chemical manufacturing process units meeting the
condition specified in Sec. 63.100(c) of this subpart, according to the
provisions in either paragraph (b) or (c) of this section. Whenever a
leak is detected, the owner or operator shall comply with the
requirements in paragraph (d) of this section.
(1) The heat exchange system is operated with the minimum pressure
on the cooling water side at least 35
[[Page 211]]
kilopascals greater than the maximum pressure on the process side.
(2) There is an intervening cooling fluid, containing less than 5
percent by weight of total hazardous air pollutants listed in table 4 of
this subpart, between the process and the cooling water. This
intervening fluid serves to isolate the cooling water from the process
fluid and the intervening fluid is not sent through a cooling tower or
discharged. For purposes of this section, discharge does not include
emptying for maintenance purposes.
(3) The once-through heat exchange system is subject to a National
Pollution Discharge Elimination System (NPDES) permit with an allowable
discharge limit of 1 part per million or less above influent
concentration or 10 percent or less above influent concentration,
whichever is greater.
(4) The once-through heat exchange system is subject to an NPDES
permit that:
(i) Requires monitoring of a parameter(s) or condition(s) to detect
a leak of process fluids into cooling water;
(ii) Specifies or includes the normal range of the parameter or
condition;
(iii) Requires monitoring for the parameters selected as leak
indicators no less frequently than monthly for the first six months and
quarterly thereafter; and
(iv) Requires the owner or operator to report and correct leaks to
the cooling water when the parameter or condition exceeds the normal
range.
(5) The recirculating heat exchange system is used to cool process
fluids that contain less than 5 percent by weight of total hazardous air
pollutants listed in table 4 of this subpart.
(6) The once-through heat exchange system is used to cool process
fluids that contain less than 5 percent by weight of total hazardous air
pollutants listed in table 9 of subpart G of this part.
(b) The owner or operator who elects to comply with the requirements
of paragraph (a) of this section by monitoring the cooling water for the
presence of one or more organic hazardous air pollutants or other
representative substances whose presence in cooling water indicates a
leak shall comply with the requirements specified in paragraphs (b)(1)
through (b)(6) of this section. The cooling water shall be monitored for
total hazardous air pollutants, total volatile organic compounds, total
organic carbon, one or more speciated HAP compounds, or other
representative substances that would indicate the presence of a leak in
the heat exchange system.
(1) The cooling water shall be monitored monthly for the first 6
months and quarterly thereafter to detect leaks.
(2)(i) For recirculating heat exchange systems (cooling tower
systems), the monitoring of speciated hazardous air pollutants or total
hazardous air pollutants refers to the hazardous air pollutants listed
in table 4 of this subpart.
(ii) For once-through heat exchange systems, the monitoring of
speciated hazardous air pollutants or total hazardous air pollutants
refers to the hazardous air pollutants listed in table 9 of subpart G of
this part.
(3) The concentration of the monitored substance(s) in the cooling
water shall be determined using any EPA-approved method listed in part
136 of this chapter as long as the method is sensitive to concentrations
as low as 10 parts per million and the same method is used for both
entrance and exit samples. Alternative methods may be used upon approval
by the Administrator.
(4) The samples shall be collected either at the entrance and exit
of each heat exchange system or at locations where the cooling water
enters and exits each heat exchanger or any combination of heat
exchangers.
(i) For samples taken at the entrance and exit of recirculating heat
exchange systems, the entrance is the point at which the cooling water
leaves the cooling tower prior to being returned to the process
equipment and the exit is the point at which the cooling water is
introduced to the cooling tower after being used to cool the process
fluid.
(ii) For samples taken at the entrance and exit of once-through heat
exchange systems, the entrance is the point at which the cooling water
enters and the exit is the point at which the cooling water exits the
plant site or chemical manufacturing process units.
(iii) For samples taken at the entrance and exit of each heat
exchanger
[[Page 212]]
or any combination of heat exchangers in chemical manufacturing process
units, the entrance is the point at which the cooling water enters the
individual heat exchanger or group of heat exchangers and the exit is
the point at which the cooling water exits the heat exchanger or group
of heat exchangers.
(5) A minimum of three sets of samples shall be taken at each
entrance and exit as defined in paragraph (b)(4) of this section. The
average entrance and exit concentrations shall then be calculated. The
concentration shall be corrected for the addition of any makeup water or
for any evaporative losses, as applicable.
(6) A leak is detected if the exit mean concentration is found to be
greater than the entrance mean using a one-sided statistical procedure
at the 0.05 level of significance and the amount by which it is greater
is at least 1 part per million or 10 percent of the entrance mean,
whichever is greater.
(c) The owner or operator who elects to comply with the requirement
of paragraph (a) of this section by monitoring using a surrogate
indicator of heat exchange system leaks shall comply with the
requirements specified in paragraphs (c)(1) through (c)(3) of this
section. Surrogate indicators that could be used to develop an
acceptable monitoring program are ion specific electrode monitoring, pH,
conductivity or other representative indicators.
(1) The owner or operator shall prepare and implement a monitoring
plan that documents the procedures that will be used to detect leaks of
process fluids into cooling water. The plan shall require monitoring of
one or more surrogate indicators or monitoring of one or more process
parameters or other conditions that indicate a leak. Monitoring that is
already being conducted for other purposes may be used to satisfy the
requirements of this section. The plan shall include the information
specified in paragraphs (c)(1)(i) and (c)(1)(ii) of this section.
(i) A description of the parameter or condition to be monitored and
an explanation of how the selected parameter or condition will reliably
indicate the presence of a leak.
(ii) The parameter level(s) or conditions(s) that shall constitute a
leak. This shall be documented by data or calculations showing that the
selected levels or conditions will reliably identify leaks. The
monitoring must be sufficiently sensitive to determine the range of
parameter levels or conditions when the system is not leaking. When the
selected parameter level or condition is outside that range, a leak is
indicated.
(iii) The monitoring frequency which shall be no less frequent than
monthly for the first 6 months and quarterly thereafter to detect leaks.
(iv) The records that will be maintained to document compliance with
the requirements of this section.
(2) If a substantial leak is identified by methods other than those
described in the monitoring plan and the method(s) specified in the plan
could not detect the leak, the owner or operator shall revise the plan
and document the basis for the changes. The owner or operator shall
complete the revisions to the plan no later than 180 days after
discovery of the leak.
(3) The owner or operator shall maintain, at all times, the
monitoring plan that is currently in use. The current plan shall be
maintained on-site, or shall be accessible from a central location by
computer or other means that provides access within 2 hours after a
request. If the monitoring plan is superseded, the owner or operator
shall retain the most recent superseded plan at least until 5 years from
the date of its creation. The superseded plan shall be retained on-site
(or accessible from a central location by computer or other means that
provides access within two hours after a request) for at least 6 months
after its creation.
(d) If a leak is detected according to the criteria of paragraph (b)
or (c) of this section, the owner or operator shall comply with the
requirements in paragraphs (d)(1) and (d)(2) of this section, except as
provided in paragraph (e) of this section.
(1) The leak shall be repaired as soon as practical but not later
than 45 calendar days after the owner or operator receives results of
monitoring tests indicating a leak. The leak shall be repaired unless
the owner or operator
[[Page 213]]
demonstrates that the results are due to a condition other than a leak.
(2) Once the leak has been repaired, the owner or operator shall
confirm that the heat exchange system has been repaired within 7
calendar days of the repair or startup, whichever is later.
(e) Delay of repair of heat exchange systems for which leaks have
been detected is allowed if the equipment is isolated from the process.
Delay of repair is also allowed if repair is technically infeasible
without a shutdown and any one of the conditions in paragraph (e)(1) or
(e)(2) of this section is met. All time periods in paragraphs (e)(1) and
(e)(2) of this section shall be determined from the date when the owner
or operator determines that delay of repair is necessary.
(1) If a shutdown is expected within the next 2 months, a special
shutdown before that planned shutdown is not required.
(2) If a shutdown is not expected within the next 2 months, the
owner or operator may delay repair as provided in paragraph (e)(2)(i) or
(e)(2)(ii) of this section. Documentation of a decision to delay repair
shall state the reasons repair was delayed and shall specify a schedule
for completing the repair as soon as practical.
(i) If a shutdown for repair would cause greater emissions than the
potential emissions from delaying repair, the owner or operator may
delay repair until the next shutdown of the process equipment associated
with the leaking heat exchanger. The owner or operator shall document
the basis for the determination that a shutdown for repair would cause
greater emissions than the emissions likely to result from delaying
repair as specified in paragraphs (e)(2)(i)(A) and (e)(2)(i)(B) of this
section.
(A) The owner or operator shall calculate the potential emissions
from the leaking heat exchanger by multiplying the concentration of
total hazardous air pollutants listed in table 4 of this subpart in the
cooling water from the leaking heat exchanger by the flowrate of the
cooling water from the leaking heat exchanger by the expected duration
of the delay. The owner or operator may calculate potential emissions
using total organic carbon concentration instead of total hazardous air
pollutants listed in table 4 of this subpart.
(B) The owner or operator shall determine emissions from purging and
depressurizing the equipment that will result from the unscheduled
shutdown for the repair.
(ii) If repair is delayed for reasons other than those specified in
paragraph (e)(2)(i) of this section, the owner or operator may delay
repair up to a maximum of 120 calendar days. The owner shall demonstrate
that the necessary parts or personnel were not available.
(f)(1) Required records. The owner or operator shall retain the
records identified in paragraphs (f)(1)(i) through (f)(1)(iv) of this
section as specified in Sec. 63.103(c)(1).
(i) Monitoring data required by this section indicating a leak and
the date when the leak was detected, and if demonstrated not to be a
leak, the basis for that determination;
(ii) Records of any leaks detected by procedures subject to
paragraph (c)(2) of this section and the date the leak was discovered;
(iii) The dates of efforts to repair leaks; and
(iv) The method or procedure used to confirm repair of a leak and
the date repair was confirmed.
(2) Reports. If an owner or operator invokes the delay of repair
provisions for a heat exchange system, the following information shall
be submitted in the next semi-annual periodic report required by Sec.
63.152(c) of subpart G of this part. If the leak remains unrepaired, the
information shall also be submitted in each subsequent periodic report,
until repair of the leak is reported.
(i) The owner or operator shall report the presence of the leak and
the date that the leak was detected.
(ii) The owner or operator shall report whether or not the leak has
been repaired.
(iii) The owner or operator shall report the reason(s) for delay of
repair. If delay of repair is invoked due to the reasons described in
paragraph (e)(2) of this section, documentation of emissions estimates
must also be submitted.
[[Page 214]]
(iv) If the leak remains unrepaired, the owner or operator shall
report the expected date of repair.
(v) If the leak is repaired, the owner or operator shall report the
date the leak was successfully repaired.
[62 FR 2733, Jan. 17, 1997]
Sec. 63.105 Maintenance wastewater requirements.
(a) Each owner or operator of a source subject to this subpart shall
comply with the requirements of paragraphs (b) through (e) of this
section for maintenance wastewaters containing those organic HAP's
listed in table 9 of subpart G of this part.
(b) The owner or operator shall prepare a description of maintenance
procedures for management of wastewaters generated from the emptying and

Sec. 63.106 Implementation and enforcement.
(a) This subpart can be implemented and enforced by the U.S. EPA, or
a delegated authority such as the applicable State, local, or Tribal
agency. If the U.S. EPA Administrator has delegated authority to a
State, local, or Tribal agency, then that agency, in addition to the
U.S. EPA, has the authority to implement and enforce this subpart.
Contact the applicable U.S. EPA Regional Office to find out if
implementation and enforcement of this subpart is delegated to a State,
local, or Tribal agency.
(b) In delegating implementation and enforcement authority of this
subpart to a State, local, or Tribal agency under subpart E of this
part, the authorities contained in paragraph (c) of this section are
retained by the Administrator of U.S. EPA and cannot be transferred to
the State, local, or Tribal agency.
(c) The authorities that cannot be delegated to State, local, or
Tribal agencies are as specified in paragraphs (c)(1) through (4) of
this section.
(1) Approval of alternatives to requirements in Sec. Sec. 63.100,
63.102, and 63.104. Where these standards reference another subpart, the
cited provisions will be delegated according to the delegation
provisions of the referenced subpart.

Sec. 63.107 Identification of process vents subject to this subpart.
(a) The owner or operator shall use the criteria specified in this
Sec. 63.107 to
[[Page 215]]
determine whether there are any process vents associated with an air
oxidation reactor, distillation unit, or reactor that is in a source
subject to this subpart. A process vent is the point of discharge to the
atmosphere (or the point of entry into a control device, if any) of a
gas stream if the gas stream has the characteristics specified in
paragraphs (b) through (h) of this section, or meets the criteria
specified in paragraph (i) of this section.
(b) Some, or all, of the gas stream originates as a continuous flow
from an air oxidation reactor, distillation unit, or reactor during
operation of the chemical manufacturing process unit.
(c) The discharge to the atmosphere (with or without passing through
a control device) meets at least one of the conditions specified in
paragraphs (c)(1) through (3) of this section.
(1) Is directly from an air oxidation reactor, distillation unit, or
reactor; or
(2) Is from an air oxidation reactor, distillation unit, or reactor
after passing solely (i.e., without passing through any other unit
operation for a process purpose) through one or more recovery devices
within the chemical manufacturing process unit; or
(3) Is from a device recovering only mechanical energy from a gas
stream that comes either directly from an air oxidation reactor,
distillation unit, or reactor, or from an air oxidation reactor,
distillation unit, or reactor after passing solely (i.e., without
passing through any other unit operation for a process purpose) through
one or more recovery devices within the chemical manufacturing process
unit.
(d) The gas stream contains greater than 0.005 weight percent total
organic HAP at the point of discharge to the atmosphere (or at the point
of entry into a control device, if any).
(e) The air oxidation reactor, distillation unit, or reactor is part
of a chemical manufacturing process unit that meets the criteria of
Sec. 63.100(b).
(f) The gas stream is in the gas phase from the point of origin at
the air oxidation reactor, distillation unit, or reactor to the point of
discharge to the atmosphere (or to the point of entry into a control
device, if any).
(g) The gas stream is discharged to the atmosphere either on-site,
off-site, or both.
(h) The gas stream is not any of the items identified in paragraphs
(h)(1) through (9) of this section.
(1) A relief valve discharge.
(2) A leak from equipment subject to subpart H of this part.
(3) A gas stream going to a fuel gas system as defined in Sec.
63.101.
(4) A gas stream exiting a control device used to comply with Sec.
63.113.
(5) A gas stream transferred to other processes (on-site or off-
site) for reaction or other use in another process (i.e., for chemical
value as a product, isolated intermediate, byproduct, or coproduct, or
for heat value).
(6) A gas stream transferred for fuel value (i.e., net positive
heating value), use, reuse, or for sale for fuel value, use, or reuse.
(7) A storage vessel vent or transfer operation vent subject to
Sec. 63.119 or Sec. 63.126.
(8) A vent from a waste management unit subject to Sec. Sec. 63.132
through 63.137.
(9) A gas stream exiting an analyzer.
(i) The gas stream would meet the characteristics specified in
paragraphs (b) through (g) of this section, but, for purposes of
avoiding applicability, has been deliberately interrupted, temporarily
liquefied, routed through any item of equipment for no process purpose,
or disposed of in a flare that does not meet the criteria in Sec.
63.11(b), or an incinerator that does not reduce emissions of organic
HAP by 98 percent or to a concentration of 20 parts per million by
volume, whichever is less stringent.

Sec. 63.112 Emission standard.
(a) The owner or operator of an existing source subject to the
requirements of this subpart shall control emissions of organic HAP's to
the level represented by the following equation:
EA = 0.02[Sigma] EPV1 + [Sigma] EPV2 +
0.05[Sigma] ES1 + [Sigma] ES2 + 0.02[Sigma]
ETR1 + [Sigma] ETR2 + [Sigma] EWW1C +
[Sigma] EWW2
where:
EA = Emission rate, megagrams per year, allowed for the
source.
0.02[Sigma] EPV1 = Sum of the residual emissions, megagrams
per year, from all Group 1 process vents, as defined in Sec.
63.111 of this subpart.
[Sigma] EPV2 = Sum of the emissions, megagrams per year, from
all Group 2 process vents as defined in Sec. 63.111 of this
subpart.
0.05[Sigma] ES1 = Sum of the residual emissions, megagrams
per year, from all Group 1 storage vessels, as defined in
Sec. 63.111 of this subpart.
[Sigma] ES2 = Sum of the emissions, megagrams per year, from
all Group 2 storage vessels, as defined in Sec. 63.111 of
this subpart.
0.02[Sigma] ETR1 = Sum of the residual emissions, megagrams
per year, from all Group 1 transfer racks, as defined in Sec.
63.111 of this subpart.
[Sigma] ETR2 = Sum of the emissions, megagrams per year, from
all Group 2 transfer racks, as defined in Sec. 63.111 of this
subpart.
[Sigma] EWW1C = Sum of the residual emissions from all Group
1 wastewater streams, as defined in Sec. 63.111 of this
subpart. This term is calculated for each Group 1 stream
according to the equation for EWW1C in Sec.
63.150(g)(5)(i) of this subpart.
[Sigma] EWW2 = Sum of emissions from all Group 2 wastewater
streams, as defined in Sec. 63.111 of this subpart.
The emissions level represented by this equation is dependent on the
collection of emission points in the source. The level is not fixed and
can change as the emissions from each emission point change or as the
number of emission points in the source changes.
(b) The owner or operator of a new source subject to the
requirements of this subpart shall control emissions of organic HAP's to
the level represented by the equation in paragraph (a) of this section.
(c) The owner or operator of an existing source shall demonstrate
compliance with the emission standard in paragraph (a) of this section
by following the procedures specified in paragraph (e) of this section
for all emission points, or by following the emissions averaging
compliance approach specified in paragraph (f) of this section for some
emission points and the procedures specified in paragraph (e) of this
section for all other emission points within the source.
(d) The owner or operator of a new source shall demonstrate
compliance with the emission standard in paragraph (b) of this section
only by following the procedures in paragraph (e) of this section. The
owner or operator of a new source may not use the emissions averaging
compliance approach.

subpart, the leak inspection provisions in Sec. 63.148, and the
provisions in Sec. 63.149 of this subpart.
(1) The owner or operator using this compliance approach shall also
comply with the requirements of Sec. 63.151 and Sec. 63.152 of this
subpart, as applicable.
(2) The owner or operator using this compliance approach is not
required to calculate the annual emission rate specified in paragraph
(a) of this section.
(3) When emissions of different kinds (e.g., emissions from process
vents, transfer operations, storage vessels, process wastewater, and/or
in-process equipment subject to Sec. 63.149 of this subpart) are
combined, and at least one of the emission streams would be classified
as Group 1 in the absence of combination with other emission streams,
the owner or operator shall comply with the requirements of either
paragraph (e)(3)(i) or paragraph (e)(3)(ii) of this section.

paragraphs (e)(3)(ii)(A) through (e)(3)(ii)(E) of this section which
applies to any individual emission stream that is included in the
combined stream, where either that emission stream would be classified
as Group 1 in the absence of combination with other emission streams, or
the owner chooses to consider that emission stream to be Group 1 for
purposes of this paragraph. Compliance with the first applicable set of
requirements identified in paragraphs (e)(3)(ii)(A) through
(e)(3)(ii)(E) of this section constitutes compliance with all other
requirements in paragraphs (e)(3)(ii)(A) through (e)(3)(ii)(E) of this
section applicable to other types of emissions in the combined stream.

some of the emission points within the source to different levels than
specified under Sec. Sec. 63.113 through 63.148 of this subpart by
using an emissions averaging compliance approach as long as the overall
emissions for the source do not exceed the emission level specified in
paragraph (a) of this section. The owner or operator using emissions
averaging must meet the requirements in paragraphs (f)(1) and (f)(2) of
this section.

to using only the procedures in paragraph (e) of this section to comply
with the emission standard in paragraph (a) of this section.
(h) Where the provisions of this subpart require a performance test,
waiver of that requirement shall be addressed only as provided in Sec.
63.103(b)(5) of subpart F of this part.

[[Page 248]]
(f) Notwithstanding any other provisions of this subpart, in any
case where a process vent includes one or more gas streams that are not

streams'' for purposes of this paragraph), and one or more gas streams
that meet the criteria in Sec. 63.107(b) through (h) or the criteria in
Sec. 63.107(i) (hereafter called ``HON streams'' for purposes of this
paragraph), the owner or operator may elect to comply with paragraphs
(f)(1) through (3) of this section.
(1) The owner or operator may determine the characteristics (flow
rate, total organic HAP concentration, and TRE index value) for each HON
stream, or combination of HON streams, at a representative point as near
as practical to, but before, the point at which it is combined with one
or more non-HON streams.
(2) If one or more of the HON streams, or combinations of HON
streams, has the characteristics (determined at the location specified
in paragraph (f)(1) of this section) associated with a Group 1 process
vent, the combined vent stream is a Group 1 process vent. Except as
specified in paragraph (f)(3) of this section, if none of the HON
streams, or combinations of HON streams, when determined at the location
specified in paragraph (f)(1) of this section, has the characteristics
associated with a Group 1 process vent, the combined vent stream is a
Group 2 process vent regardless of the TRE index value determined at the
location specified in Sec. 63.115(a). If the combined vent stream is a
Group 2 process vent as determined by the previous sentence, but one or
more of the HON streams, or combinations of HON streams, has a TRE index
value greater than 1 but less than or equal to 4, the combined vent
stream is a process vent with a TRE index value greater than 1 but less
than or equal to 4. In this case, the owner or operator shall monitor
the combined vent stream as required by Sec. 63.114(b).
(3) Paragraphs (f)(1) and (2) of this section are not intended to
apply instead of any other subpart of this part. If another subpart of
this part applies to one or more of the non-HON streams contributing to
the combined vent stream, that subpart may impose emission control
requirements such as, but not limited to, requiring the combined vent
stream to be classified and controlled as a Group 1 process vent.

(D) The performance test or design evaluation shall determine
compliance across the combination of treatment processes or control
devices. If a performance test is conducted, the ``inlet'' shall be the
point at which the wastewater stream or residual enters the first
treatment process, or the vented gas stream enters the first control
device. The ``outlet'' shall be the point at which the treated
wastewater stream exits the last treatment process, or the vented gas
stream exits the last control device.
(ii)(A) For combinations of treatment processes, each treatment
process shall meet the applicable requirements of Sec. 63.133 through
Sec. 63.137 of this subpart except as provided in paragraph (a)(3) of

operator from conducting a performance test.
(1) A design evaluation and supporting documentation that addresses
the operating characteristics of the treatment process and that is based
on operation at a representative wastewater stream flow rate and a
concentration under which it would be most difficult to demonstrate
compliance. For closed biological treatment processes, the actual mass

flow rate of Table 8 or Table 9 compounds exiting the treatment process
shall be the sum of the mass flow rate of Table 8 or Table 9 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.
(2) Performance tests conducted using test methods and procedures
that meet the applicable requirements specified in Sec. 63.145 of this
subpart.
(3) The provisions of paragraphs (j)(1) and (j)(2) of this section

(3) Treat the residual to destroy the total combined mass flow rate
of Table 8 and/or Table 9 compounds by 99 percent or more, as determined
by the procedures specified in Sec. 63.145(c) or (d) of this subpart.

[62 FR 2762, Jan. 17, 1997]
Sec. 63.144 Process wastewater provisions--test methods and procedures
for determining applicability and Group 1/Group 2 determinations
(determining which wastewater streams require control).
(a) Procedures to determine applicability. An owner or operator
shall comply with paragraph (a)(1) or (a)(2) of this section for each
wastewater
[[Page 305]]
stream to determine which wastewater streams require control for Table 8
and/or Table 9 compounds. The owner or operator may use a combination of
the approaches in paragraphs (a)(1) and (a)(2) of this section for
different wastewater streams generated at the source.
(1) Determine Group 1 or Group 2 status. Determine whether a
wastewater stream is a Group 1 or Group 2 wastewater stream in
accordance with paragraphs (b) and (c) of this section.
(2) Designate as Group 1. An owner or operator may designate as a
Group 1 wastewater stream a single wastewater stream or a mixture of
wastewater streams. The owner or operator is not required to determine
the concentration or flow rate for each designated Group 1 wastewater
stream for the purposes of this section.
(b) Procedures to establish concentrations, when determining Group
status under paragraph (a)(1) of this section. An owner or operator who
elects to comply with the requirements of paragraph (a)(1) of this
section shall determine the annual average concentration for Table 8
and/or Table 9 compounds according to paragraph (b)(1) of this section
for existing sources or paragraph (b)(2) of this section for new
sources. The annual average concentration shall be a flow weighted
average representative of actual or anticipated operation of the
chemical manufacturing process unit generating the wastewater over a
designated 12 month period. For flexible operation units, the owner or
operator shall consider the anticipated production over the designated
12 month period and include all wastewater streams generated by the
process equipment during this period. The owner/operator is not required
to determine the concentration of Table 8 or Table 9 compounds that are
not reasonably expected to be in the process.
(1) Existing sources. An owner or operator of an existing source who
elects to comply with the requirements of paragraph (a)(1) of this
section shall determine the flow weighted total annual average
concentration for Table 9 compounds. For the purposes of this section,
the term concentration, whether concentration is used alone or with
other terms, may be adjusted by multiplying by the compound-specific
fraction measured (Fm) factors listed in table 34 of this subpart unless
determined by the methods in Sec. 63.144(b)(5)(i)(A) and/or (B). When
concentration is determined by Method 305 as specified in Sec.
63.144(b)(5)(i)(B), concentration may be adjusted by dividing by the
compound-specific Fm factors listed in table 34 of this subpart. When
concentration is determined by Method 25D as specified in Sec.
63.144(b)(5)(i)(A), concentration may not be adjusted by the compound-
specific Fm factors listed in table 34 of this subpart. Compound-
specific Fm factors may be used only when concentrations of individual
compounds are determined or when only one compound is in the wastewater
stream. Flow weighted total annual average concentration for Table 9
compounds means the total mass of Table 9 compounds occurring in the
wastewater stream during the designated 12-month period divided by the
total mass of the wastewater stream during the same designated 12-month
period. The total annual average concentration shall be determined for
each wastewater stream either at the point of determination, or
downstream of the point of determination with adjustment for
concentration changes made according to paragraph (b)(6) of this
section. The procedures specified in paragraphs (b)(3), (b)(4), and
(b)(5) of this section are considered acceptable procedures for
determining the annual average concentration. They may be used in
combination, and no one procedure shall take precedence over another.
(2) New sources. An owner or operator of a new source who elects to
comply with the requirements of paragraph (a)(1) of this section shall
determine both the flow weighted total annual average concentration for
Table 9 compounds and the flow weighted annual average concentration for
each Table 8 compound. For the purposes of this section, the term
concentration, whether concentration is used alone or with other terms,
may be adjusted by multiplying by the compound-specific Fm factors
listed in table 34 of this subpart unless determined by the methods in
Sec. 63.144(b)(5)(i)(A) and/or (B). When concentration is determined by
Method 305
[[Page 306]]
as specified in Sec. 63.144(b)(5)(i)(B), concentration may be adjusted
by dividing by the compound-specific Fm factors listed in table 34 of
this subpart. When concentration is determined by Method 25D as
specified in Sec. 63.144(b)(5)(i)(A), concentration may not be adjusted
by the compound-specific Fm factors listed in table 34 of this subpart.
Compound-specific fraction measured factors are compound specific and
shall be used only when concentration of individual compounds are
determined or when only one compound is in the wastewater stream. The
flow weighted annual average concentration of each Table 8 compound
means the mass of each Table 8 compound occurring in the wastewater
stream during the designated 12-month period divided by the total mass
of the wastewater stream during the same designated 12-month period.
Flow weighted total annual average concentration for Table 9 compounds
means the total mass of Table 9 compounds occurring in the wastewater
stream during the designated 12-month period divided by the total mass
of the wastewater stream during the same designated 12-month period. The
annual average concentration shall be determined for each wastewater
stream either at the point of determination, or downstream of the point
of determination with adjustment for concentration changes made
according to paragraph (b)(6) of this section. Procedures specified in
paragraphs (b)(3), (b)(4), and (b)(5) of this section are considered
acceptable procedures for determining the annual average concentration.
They may be used in combination, and no one procedure shall take
precedence over another.
(3) Knowledge of the wastewater. Where knowledge is used to
determine the annual average concentration, the owner or operator shall
provide sufficient information to document the annual average
concentration for wastewater streams determined to be Group 2 wastewater
streams. Documentation to determine the annual average concentration is
not required for Group 1 streams. Examples of acceptable documentation
include material balances, records of chemical purchases, process
stoichiometry, or previous test results. If test data are used, the
owner or operator shall provide documentation describing the testing
protocol and the means by which any losses of volatile compounds during
sampling, and the bias and accuracy of the analytical method, were
accounted for in the determination.
(4) Bench-scale or pilot-scale test data. Where bench-scale or
pilot-scale test data are used to determine the annual average
concentration, the owner or operator shall provide sufficient
information to document that the data are representative of the actual
annual average concentration, or are reliably indicative of another
relevant characteristic of the wastewater stream that could be used to
predict the annual average concentration. For concentration data, the
owner or operator shall also provide documentation describing the
testing protocol, and the means by which any losses of volatile
compounds during sampling, and the bias and accuracy of the analytical
method, were accounted for in the determination of annual average
concentration.
(5) Test data from sampling at the point of determination or at a
location downstream of the point of determination. Where an owner or
operator elects to comply with paragraph (a)(1) of this section by
measuring the concentration for the relevant Table 8 or Table 9
compounds, the owner or operator shall comply with the requirements of
this paragraph. For each wastewater stream, measurements shall be made
either at the point of determination, or downstream of the point of
determination with adjustment for concentration changes made according
to paragraph (b)(6) of this section. A minimum of three samples from
each wastewater stream shall be taken. Samples may be grab samples or
composite samples.
(i) Methods. The owner or operator shall use any of the methods
specified in paragraphs (b)(5)(i)(A) through (b)(5)(i)(F) of this
section.
(A) Method 25D. Use procedures specified in Method 25D of 40 CFR
part 60, appendix A.
(B) Method 305. Use procedures specified in Method 305 of 40 CFR
part 63, appendix A.
(C) Methods 624 and 625. Use procedures specified in Methods 624 and
625
[[Page 307]]
of 40 CFR part 136, appendix A and comply with the sampling protocol
requirements specified in paragraph (b)(5)(ii) of this section. If these
methods are used to analyze one or more compounds that are not on the
method's published list of approved compounds, the Alternative Test
Procedure specified in 40 CFR 136.4 and 136.5 shall be followed. For
Method 625, make corrections to the compounds for which the analysis is
being conducted based on the accuracy as recovery factors in Table 7 of
the method.
(D) Method 1624 and Method 1625. Use procedures specified in Method
1624 and Method 1625 of 40 CFR part 136, appendix A and comply with the
requirements specified in paragraph (b)(5)(ii) of this section. If these
methods are used to analyze one or more compounds that are not on the
method's published list of approved compounds, the Alternative Test
Procedure specified in 40 CFR 136.4 and 136.5 shall be followed.
(E) Other EPA method(s). Use procedures specified in the method and
comply with the requirements specified in paragraphs (b)(5)(ii) and
either paragraph (b)(5)(iii)(A) or (b)(5)(iii)(B) of this section.
(F) Method(s) other than EPA method. Use procedures specified in the
method and comply with the requirements specified in paragraphs
(b)(5)(ii) and (b)(5)(iii)(A) of this section.
(G) Method 8260B. Use procedures specified in Method 8260B in the
SW-846 Compendium of Methods.
(H) Method 316. Use Method 316 to determine formaldehyde
concentration.
(ii) Sampling plan. The owner or operator who is expressly referred
to this paragraph by provisions of this subpart shall prepare a sampling
plan. Wastewater samples shall be collected using sampling procedures
which minimize loss of organic compounds during sample collection and
analysis and maintain sample integrity. The sample plan shall include
procedures for determining recovery efficiency of the relevant hazardous
air pollutants listed in table 8 or table 9 of this subpart. An example
of an acceptable sampling plan would be one that incorporates similar
sampling and sample handling requirements to those of Method 25D of 40
CFR part 60, appendix A. The sampling plan shall be maintained at the
facility.
(iii) Validation of methods. The owner or operator shall validate
EPA methods other than Methods 25D, 305, 624, 625, 1624, and 1625 using
the procedures specified in paragraph (b)(5)(iii)(A) or (b)(5)(iii)(B)
of this section. The owner or operator shall validate other methods as
specified in paragraph (b)(5)(iii)(A) of this section.
(A) Validation of EPA methods and other methods. The method used to
measure organic hazardous air pollutants concentrations in the
wastewater shall be validated according to section 5.1 or 5.3, and the
corresponding calculations in section 6.1 or 6.3, of Method 301 of
appendix A of this part. The data are acceptable if they meet the
criteria specified in section 6.1.5 or 6.3.3 of Method 301 of appendix A
of this part. If correction is required under section 6.3.3 of Method
301 of appendix A of this part, the data are acceptable if the
correction factor is within the range 0.7 to 1.30. Other sections of
Method 301 of appendix A of this part are not required. The
concentrations of the individual organic hazardous air pollutants
measured in the water may be corrected to their concentrations had they
been measured by Method 305 of appendix A of this part, by multiplying
each concentration by the compound-specific fraction measured (Fm)
factor listed in table 34 of this subpart.
(B) Validation for EPA methods. Follow the procedures as specified
in ``Alternative Validation Procedure for EPA Waste Methods'' 40 CFR
part 63, appendix D.
(iv) Calculations of average concentration. The average
concentration for each individually speciated Table 8 compound shall be
calculated by adding the individual values determined for the specific
compound in each sample and dividing by the number of samples. The total
average concentration of Table 9 compounds shall be calculated by first
summing the concentration of the individual compounds to obtain a total
hazardous air pollutants concentration for the sample; add the sample
totals and then divide by the number of samples in the run to obtain the
sample average for the run. If the method used does not speciate the
[[Page 308]]
compounds, the sample results should be added and this total divided by
the number of samples in the run to obtain the sample average for the
run.
(6) Adjustment for concentrations determined downstream of the point
of determination. The owner or operator shall make corrections to the
annual average concentration or total annual average concentration when
the concentration is determined downstream of the point of determination
at a location where: two or more wastewater streams have been mixed; one
or more wastewater streams have been treated; or, losses to the
atmosphere have occurred. The owner or operator shall make the
adjustments either to the individual data points or to the final annual
average concentration.
(c) Procedures to determine flow rate, when evaluating Group status
under paragraph (a)(1) of this section. An owner or operator who elects
to comply with paragraph (a)(1) of this section shall determine the
annual average flow rate of the wastewater stream either at the point of
determination for each wastewater stream, or downstream of the point of
determination with adjustment for flow rate changes made according to
paragraph (c)(4) of this section. These procedures may be used in
combination for different wastewater streams at the source. The annual
average flow rate for the wastewater stream shall be representative of
actual or anticipated operation of the chemical manufacturing process
unit generating the wastewater over a designated 12-month period. The
owner or operator shall consider the total annual wastewater volume
generated by the chemical manufacturing process unit. If the chemical
manufacturing process unit is a flexible operation unit, the owner or
operator shall consider all anticipated production in the process
equipment over the designated 12-month period. The procedures specified
in paragraphs (c)(1), (c)(2), and (c)(3) of this section are considered
acceptable procedures for determining the flow rate. They may be used in
combination, and no one procedure shall take precedence over another.
(1) Knowledge of the wastewater. The owner or operator may use
knowledge of the wastewater stream and/or the process to determine the
annual average flow rate. The owner or operator shall use the maximum
expected annual average production capacity of the process unit,
knowledge of the process, and/or mass balance information to either:
Estimate directly the annual average wastewater flow rate; or estimate
the total annual wastewater volume and then divide total volume by
525,600 minutes in a year. Where knowledge is used to determine the
annual average flow rate, the owner or operator shall provide sufficient
information to document the flow rate for wastewater streams determined
to be Group 2 wastewater streams. Documentation to determine the annual
average flow rate is not required for Group 1 streams.
(2) Historical records. The owner or operator may use historical
records to determine the annual average flow rate. Derive the highest
annual average flow rate of wastewater from historical records
representing the most recent 5 years of operation or, if the process
unit has been in service for less than 5 years but at least 1 year, from
historical records representing the total operating life of the process
unit. Where historical records are used to determine the annual average
flow rate, the owner or operator shall provide sufficient information to
document the flow rate for wastewater streams determined to be Group 2
wastewater streams. Documentation to determine the annual average flow
rate is not required for Group 1 streams.
(3) Measurements of flow rate. Where an owner or operator elects to
comply with paragraph (a)(1) of this section by measuring the flow rate,
the owner or operator shall comply with the requirements of this
paragraph. Measurements shall be made at the point of determination, or
at a location downstream of the point of determination with adjustments
for flow rate changes made according to paragraph (c)(4) of this
section. Where measurement data are used to determine the annual average
flow rate, the owner or operator shall provide sufficient information to
document the flow rate for wastewater streams determined to be Group 2
wastewater streams. Documentation to
[[Page 309]]
determine the annual average flow rate is not required for Group 1
streams.
(4) Adjustment for flow rates determined downstream of the point of
determination. The owner or operator shall make corrections to the
annual average flow rate of a wastewater stream when it is determined
downstream of the point of determination at a location where two or more
wastewater streams have been mixed or one or more wastewater streams
have been treated. The owner or operator shall make corrections for such
changes in the annual average flow rate.

Sec. 63.145 Process wastewater provisions--test methods and procedures
to determine compliance.
(a) General. This section specifies the procedures for performance
tests that are conducted to demonstrate compliance of a treatment
process or a control device with the control requirements specified in
Sec. 63.138 of this subpart. Owners or operators conducting a design
evaluation shall comply with the requirements of paragraph (a)(1) or
(a)(2) of this section. Owners or operators conducting a performance
test shall comply with the applicable requirements in paragraphs (a)
through (i) of this section.
(1) Performance tests and design evaluations for treatment
processes. If design steam stripper option (Sec. 63.138(d)) or RCRA
option (Sec. 63.138(h)) is selected to comply with Sec. 63.138,
neither a design evaluation nor a performance test is required. For any
other non-biological treatment process, the owner or operator shall
conduct either a design evaluation as specified in Sec. 63.138(j), or a
performance test as specified in this section. For closed biological
treatment processes, the owner or operator shall conduct either a design
evaluation as specified in Sec. 63.138(j), or a performance test as
specified in this section. For each open biological treatment process,
the owner or operator shall conduct a performance test as specified in
this section.
Note: Some open biological treatment processes may not require a
performance test. Refer to Sec. 63.145(h) and table 36 of this subpart
to determine whether the biological treatment process meets the criteria
that exempt the owner or operator from conducting a performance test.
(2) Performance tests and design evaluations for control devices.
The owner or operator shall conduct either a design evaluation as
specified in Sec. 63.139(d), or a performance test as specified in
paragraph (i) of this section for control devices other than flares and
paragraph (j) of this section for flares.
(3) Representative process unit operating conditions. Compliance
shall be demonstrated for representative operating conditions.
Operations during periods of startup, shutdown, or malfunction and
periods of nonoperation shall not constitute representative conditions.
The owner or operator shall record the process information that is
necessary to document operating conditions during the test.
(4) Representative treatment process or control device operating
conditions. Performance tests shall be conducted when the treatment
process or control device is operating at a representative inlet flow
rate and concentration. If the treatment process or control device will
be operating at several different sets of representative operating
conditions, the owner or operator shall comply with paragraphs (a)(4)(i)
and (a)(4)(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.
(i) Range of operating conditions. If the treatment process or
control device will be 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.
(ii) Consideration of residence time. If concentration and/or flow
rate to the treatment process or control device 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.
[[Page 310]]
(5) Testing equipment. All testing equipment shall be prepared and
installed as specified in the applicable test methods, or as approved by
the Administrator.
(6) Compounds not required to be considered in performance tests or
design evaluations. Compounds that meet the requirements specified in
paragraph (a)(6)(i), (a)(6)(ii), or (a)(6)(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 34 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 34 of this subpart.
(i) Compounds not used or produced by the chemical manufacturing
process unit; or
(ii) Compounds with concentrations at the point of determination
that are below 1 part per million by weight; or
(iii) Compounds with concentrations at the point of determination
that are below the lower detection limit where the lower detection limit
is greater than 1 part per million by weight. The method shall be an
analytical method for wastewater which has that compound as a target
analyte.
(7) 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. 63.138(a)(7)(i), when
wastewater is conveyed by hard-piping, shall comply with either
Sec. Sec. 63.145(a)(7)(i) or 63.145(a)(7)(ii) of this subpart. The
owner or operator complying with the requirements of Sec.
63.138(a)(7)(ii) of this subpart shall comply with the requirements of
Sec. 63.145(a)(7)(ii) of this subpart.
(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 stream enters the first treatment process in a
series of treatment processes, or prior to the first treatment process
as specified in Sec. 63.145(a)(9) of this subpart. For each series of
treatment processes, outlet concentration and flow rate shall be
measured where the wastewater stream 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 Sec. 63.145 (f) or
(g) of this subpart. When the last treatment process is either an open
or a closed aerobic biological treatment process demonstrating
compliance by using the procedures in Sec. 63.145 (f) or (g) of this
subpart, inlet and outlet concentrations and flow rates shall be
measured as provided in paragraphs (a)(7)(i)(A) and (a)(7)(i)(B) of this
section. The mass flow rates removed or destroyed by the series of
treatment processes and by the biological treatment process are all used
to calculate actual mass removal (AMR) as specified in Sec.
63.145(f)(5)(ii) of this subpart.
(A) The inlet and outlet to the series of treatment processes prior

processes to demonstrate compliance with the 95-percent mass removal
provisions for Table 8 and/or Table 9 compounds. This compliance option
is specified in Sec. 63.138(g) of this subpart. The RMR for this option
is 95-percent mass removal. The owner or operator shall comply with the
requirements specified in Sec. 63.145(g)(1) to determine AMR, Sec.
63.145 (e)(3)(ii) and (e)(4)(ii) to determine RMR, and (g)(2) of this
subpart to determine whether compliance has been demonstrated. Some
compounds may not require a performance test. Refer to Sec. 63.145(h)
and table 36 of this subpart to determine which compounds may be exempt
from the requirements of this paragraph. (Wastewater streams that are
Group 1 for both Table 8 and Table 9 compounds need only do the
compliance demonstration for Table 9 compounds.)
(1) The owner or operator shall comply with the requirements
specified in paragraphs (f)(1), (f)(2), and (f)(5) of this section to
determine AMR. References to Group 1 wastewater streams shall be deemed
Group 1 and Group 2 wastewater streams for the purposes of this
paragraph.
(2) Compare RMR to AMR. Compliance is demonstrated if the AMR is
greater than or equal to RMR.
(h) Site-specific fraction biodegraded (Fbio). The compounds listed
in table 9 of this subpart are divided into two sets for the purpose of
determining whether Fbio must be determined, and if
Fbio must be determined, which procedures may be used to
determine compound-specific kinetic parameters. These sets are
designated as lists 1 and 2 in table 36 of this subpart.
(1) Performance test exemption. If a biological treatment process
meets the requirements specified in paragraphs (h)(1)(i) and (h)(1)(ii)
of this section, the owner or operator is not required to determine
Fbio and is exempt from the applicable performance test
requirements specified in Sec. 63.138 of this subpart.
[[Page 320]]
(i) The biological treatment process meets the definition of
``enhanced biological treatment process'' in Sec. 63.111 of this
subpart.
(ii) At least 99 percent by weight of all compounds on table 36 of
this subpart that are present in the aggregate of all wastewater streams
using the biological treatment process to comply with Sec. 63.138 of
this subpart are compounds on list 1 of table 36 of this subpart.
(2) Fbio determination. If a biological treatment process does not
meet the requirement specified in paragraph (h)(1)(i) of this section,
the owner or operator shall determine Fbio for the biological
treatment process using the procedures in appendix C to part 63, and
paragraph (h)(2)(ii) of this section. If a biological treatment process
meets the requirements of paragraph (h)(1)(i) of this section but does
not meet the requirement specified in paragraph (h)(1)(ii) of this
section, the owner or operator shall determine Fbio for the
biological treatment process using the procedures in appendix C to part
63, and paragraph (h)(2)(i) of this section.
(i) Enhanced biological treatment processes. If the biological
treatment process meets the definition of ``enhanced biological
treatment process'' in Sec. 63.111 of this subpart and the wastewater
streams include one or more compounds on list 2 of table 36 of this
subpart that do not meet the criteria in paragraph (h)(1)(ii) of this
section, the owner or operator shall determine fbio for the
list 2 compounds using any of the procedures specified in appendix C of
40 CFR part 63. (The symbol ``fbio'' represents the site
specific fraction of an individual Table 8 or Table 9 compound that is
biodegraded.) The owner or operator shall calculate fbio for
the list 1 compounds using the defaults for first order biodegradation
rate constants (K1) in table 37 of subpart G and follow the
procedure explained in form III of appendix C, 40 CFR part 63, or any of
the procedures specified in appendix C, 40 CFR part 63.
(ii) Biological treatment processes that are not enhanced biological
treatment processes. For biological treatment processes that do not meet
the definition for ``enhanced biological treatment process'' in Sec.
63.111 of this subpart, the owner or operator shall determine the
fbio for the list 1 and 2 compounds using any of the
procedures in appendix C to part 63, except procedure 3 (inlet and
outlet concentration measurements). (The symbol ``fbio''
represents the site specific fraction of an individual Table 8 or Table
9 compound that is biodegraded.)
(i) Performance tests for control devices other than flares. This
paragraph applies to performance tests that are conducted to demonstrate
compliance of a control device with the efficiency limits specified in
Sec. 63.139(c). If complying with the 95-percent reduction efficiency
requirement, comply with the requirements specified in paragraphs (i)(1)
through (i)(9) of this section. If complying with the 20 ppm by volume
requirement, comply with the requirements specified in paragraphs (i)(1)
through (i)(6) and (i)(9) of this section. The 20 ppm by volume limit or
95-percent reduction efficiency requirement shall be measured as either
total organic hazardous air pollutants or as TOC minus methane and
ethane.
(1) Sampling sites. Sampling sites shall be selected using Method 1
or 1A of 40 CFR part 60, appendix A, as appropriate. For determination
of compliance with the 95 percent reduction requirement, sampling sites
shall be located at the inlet and the outlet of the control device. For
determination of compliance with the 20 parts per million by volume
limit, the sampling site shall be located at the outlet of the control
device.
(2) Concentration in gas stream entering or exiting the control
device. The concentration of total organic hazardous air pollutants or
TOC in a gas stream shall be determined as provided in this paragraph.
Samples may be grab samples or composite samples (i.e., integrated
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 3 runs.
Concentration measurements shall be determined using Method 18 of 40 CFR
part 60, appendix A. Alternatively, any other test method validated
according to the procedures in Method 301 of appendix A of this part may
be used.
[[Page 321]]
(3) Volumetric flow rate of gas stream entering or exiting the
control device. The volumetric flow rate of the gas stream shall be
determined using Method 2, 2A, 2C, or 2D of 40 CFR part 60, appendix A,
as appropriate. Volumetric flow rate measurements shall be taken at the
same time as the concentration measurements.
(4) Calculation of TOC concentration. The TOC concentration
(CGT) 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 the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JA97.014
Where:
CGT = Total concentration of TOC (minus methane and ethane)
in vented gas stream, average of samples, dry basis, parts per
million by volume.
CGS\i j\ = Concentration of sample components in vented gas stream for
sample j, dry basis, parts per million by volume.

(5) Calculation of total organic hazardous air pollutants
concentration. The owner or operator determining compliance based on
total organic hazardous air pollutants concentration (CHAP)
shall compute CHAP according to the Equation WW14, except
that only Table 9 compounds shall be summed.
(6) Percent oxygen correction for combustion control devices. If the
control device is a combustion device, comply with the requirements
specified in paragraph (i)(6)(i) of this section to determine oxygen
concentration, and in paragraph (i)(6)(ii) of this section to calculate
the percent oxygen correction.
(i) Oxygen concentration. The concentration of TOC or total organic
hazardous air pollutants shall be corrected to 3 percent oxygen if the
control device is a combustion device. The emission rate correction
factor for excess air, composite sampling (i.e., integrated sampling)
and analysis procedures of Method 3B of 40 CFR part 60, appendix A shall
be used to determine the actual oxygen concentration (%02d).
The samples shall be taken during the same time that the TOC (minus
methane or ethane) or total organic hazardous air pollutants samples are
taken.
(ii) 3 percent oxygen calculation. The concentration corrected to 3
percent oxygen (CGc), when required, shall be computed using
the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JA97.015
Where:
CGc = Concentration of TOC or organic hazardous air
pollutants corrected to 3 percent oxygen, dry basis, parts per
million by volume.
CGT = Total concentration of TOC (minus methane and ethane)
in vented gas stream, average of samples, dry basis, parts per
million by volume.
%02d = Concentration of oxygen measured in vented gas stream,
dry basis, percent by volume.
(7) Mass rate calculation. The mass rate of either TOC (minus
methane and ethane) or total organic hazardous air pollutants shall be
calculated using the following equations. Where the mass
[[Page 322]]
rate of TOC is being calculated, all organic compounds (minus methane
and ethane) measured by methods specified in paragraph (i)(2) of this
section are summed using Equations WW16 and WW17. Where the mass rate of
total organic hazardous air pollutants is being calculated, only Table 9
compounds shall be summed using Equations WW16 and WW17.
[GRAPHIC] [TIFF OMITTED] TR17JA97.016
[GRAPHIC] [TIFF OMITTED] TR17JA97.017
Where:
CGa, i, CGb, i = Concentration of TOC (minus
methane and ethane) or total organic hazardous air pollutants,
in vented gas stream, entering (CGa, i) and exiting
(CGb, i) the control device, dry basis, parts per
million by volume.
QMGa, QMGb = Mass rate of TOC (minus methane and
ethane) or total organic hazardous air pollutants, in vented
gas stream, entering (QMGa) and exiting
(QMGb) the control device, dry basis, kilograms per
hour.
MWi = Molecular weight of a component, kilogram/kilogram-
mole.
QGa, QGb = Flow rate of gas stream entering
(QGa) and exiting (QGb) the control
device, dry standard cubic meters per hour.
K2 = Constant, 41.57 x 10-9 (parts per
million)-1 (gram-mole per standard cubic meter)
(kilogram/gram), where standard temperature (gram-mole per
standard cubic meter) is 20 [deg]Celsius.
i = Identifier for a compound.
n = Number of components in the sample.
(8) Percent reduction calculation. The percent reduction in TOC
(minus methane and ethane) or total organic hazardous air pollutants
shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR17JA97.018
Where:
E = Destruction efficiency of control device, percent.
QMGa, QMGb = Mass rate of TOC (minus methane and
ethane) or total organic hazardous air pollutants, in vented
gas stream entering and exiting (QMGb) the control
device, dry basis, kilograms per hour.
(9) Compare mass destruction efficiency to required efficiency. If
complying with the 95 percent reduction efficiency requirement,
compliance is demonstrated if the mass destruction efficiency
(calculated in Equation WW18) is 95 percent or greater. If complying
with the 20 parts per million by volume limit in Sec. 63.139 (c)(1)(ii)
of this subpart, compliance is demonstrated if the outlet total organic
compound concentration, less methane and ethane, or total organic
hazardous air pollutants concentration is 20 parts per million by
volume, or less. For combustion control devices, the concentration shall
be calculated on a dry basis, corrected to 3 percent oxygen.
(j) When a flare is used to comply with Sec. 63.139(c), the owner
or operator shall comply with paragraphs (j)(1) through (3) of this
section. The owner or operator is not required to conduct a performance
test to determine percent emission reduction or outlet organic HAP or
TOC concentration.
(1) Conduct a visible emission test using the techniques specified
in Sec. 63.11(b)(4).
[[Page 323]]
(2) Determine the net heating value of the gas being combusted using
the techniques specified in Sec. 63.11(b)(6).
(3) Determine the exit velocity using the techniques specified in
either Sec. 63.11(b)(7)(i) (and Sec. 63.11(b)(7)(iii), where
applicable) or Sec. 63.11(b)(8), as appropriate.

paragraph (c) of this section, and
(ii) Conduct annual inspections according to the procedures in
paragraph (c) of this section.
(iii) Conduct annual visual inspections for visible, audible, or
olfactory indications of leaks.
(3) For each fixed roof, cover, and enclosure, the owner or operator
shall conduct initial visual inspections and semi-annual visual
inspections for visible, audible, or olfactory indications of leaks as
specified in Sec. Sec. 63.133 through 63.137 of this subpart.
(c) Each vapor collection system and closed vent system shall be
inspected according to the procedures specified in paragraphs (c)(1)
through (c)(5) of this section.
(1) Inspections shall be conducted in accordance with Method 21 of
40 CFR part 60, appendix A.
(2)(i) Except as provided in paragraph (c)(2)(ii) of this section,
the detection instrument shall meet the performance criteria of Method
21 of 40 CFR part 60, appendix A, except the instrument response factor
criteria in section 3.1.2(a) of Method 21 shall be for the average
composition of the process fluid not each individual volatile organic
compound in the stream. For process streams that contain nitrogen, air,
or other inerts which are not organic hazardous air pollutants or
volatile organic compounds, the average stream response factor shall be
calculated on an inert-free basis.
(ii) If no instrument is available at the plant site that will meet
the performance criteria specified in paragraph (c)(2)(i) of this
section, the instrument readings may be adjusted by multiplying by the
average response factor of the process fluid, calculated on an inert-
free basis as described in paragraph (c)(2)(i) of this section.
(3) The detection 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 as follows:
(i) Zero air (less than 10 parts per million hydrocarbon in air);
and
(ii) Mixtures of methane in air at a concentration less than 10,000
parts per million. A calibration gas other than methane in air may be
used if the instrument does not respond to methane or if the instrument
does not meet the performance criteria specified in paragraph (c)(2)(i)
of this section. In such cases, the calibration gas may be a mixture of
one or more of the compounds to be measured in air.
(5) An owner or operator may elect to adjust or not adjust
instrument readings for background. If an owner or operator elects to
not adjust readings for background, all such instrument readings shall
be compared directly to the applicable leak definition to determine
whether there is a leak. If an owner or operator elects to adjust
instrument readings for background, the owner or operator shall measure
background concentration using the procedures in Sec. Sec. 63.180(b)
and (c) of subpart H of this part. The owner or operator shall subtract
background reading from the maximum concentration indicated by the
instrument.
(6) The arithmetic difference between the maximum concentration
indicated by the instrument and the background level shall be compared
with 500 parts per million for determining compliance.
(d) Leaks, as indicated by an instrument reading greater than 500
parts per million above background or by visual
[[Page 328]]
inspections, shall be repaired as soon as practicable, except as
provided in paragraph (e) of this section.
(1) A first attempt at repair shall be made no later than 5 calendar
days after the leak is detected.
(2) Repair shall be completed no later than 15 calendar days after
the leak is detected, except as provided in paragraph (d)(3) of this
section.
(3) For leaks found in vapor collection systems used for transfer
operations, repairs shall be completed no later than 15 calendar days
after the leak is detected or at the beginning of the next transfer
loading operation, whichever is later.
(e) Delay of repair of a vapor collection system, closed vent
system, fixed roof, cover, or enclosure for which leaks have been
detected is allowed if the repair is technically infeasible without a
shutdown, as defined in Sec. 63.101 of subpart F of this part, or if
the owner or operator determines that emissions resulting from immediate
repair would be greater than the fugitive emissions likely to result
from delay of repair. Repair of such equipment shall be complete by the
end of the next shutdown.
(f) For each vapor collection system or closed vent system that
contains bypass lines that could divert a vent stream away from the
control device and to the atmosphere, the owner or operator shall comply
with the provisions of either paragraph (f)(1) or (f)(2) of this
section, except as provided in paragraph (f)(3) of this section.
(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 generated as specified in Sec. 63.118(a)(3)
of this subpart. The flow indicator shall be installed at the entrance
to any bypass line; or
(2) Secure the bypass line valve in the closed position with a car-
seal or a lock-and-key type configuration. A visual inspection of the
seal or closure mechanism shall be performed at least once every month
to ensure the valve is maintained in the closed position and the vent
stream is not diverted through the bypass line.
(3) Equipment such as low leg drains, high point bleeds, analyzer
vents, open-ended valves or lines, and pressure relief valves needed for
safety purposes are not subject to this paragraph.
(g) Any parts of the vapor collection system, closed vent system,
fixed roof, cover, or enclosure that are designated, as described in
paragraph (i)(1) of this section, as unsafe to inspect are exempt from
the inspection requirements of paragraphs (b)(1), (b)(2), and (b)(3)(i)
of this section if:
(1) The owner or operator determines that the equipment is unsafe to
inspect because inspecting personnel would be exposed to an imminent or
potential danger as a consequence of complying with paragraphs (b)(1),
(b)(2), or (b)(3)(i) of this section; and
(2) The owner or operator has a written plan that requires
inspection of the equipment as frequently as practicable during safe-to-
inspect times.
(h) Any parts of the vapor collection system, closed vent system,
fixed roof, cover, or enclosure that are designated, as described in
paragraph (i)(2) of this section, as difficult to inspect are exempt
from the inspection requirements of paragraphs (b)(1), (b)(2), and
(b)(3)(i) of this section if:
(1) The owner or operator determines that the equipment cannot be
inspected without elevating the inspecting personnel more than 2 meters
above a support surface; and
(2) The owner or operator has a written plan that requires
inspection of the equipment at least once every 5 years.
(i) The owner or operator shall record the information specified in
paragraphs (i)(1) through (i)(5) of this section.
(1) Identification of all parts of the vapor collection system,
closed vent system, fixed roof, cover, or enclosure that are designated
as unsafe to inspect, an explanation of why the equipment is unsafe to
inspect, and the plan for inspecting the equipment.
(2) Identification of all parts of the vapor collection system,
closed vent system, fixed roof, cover, or enclosure that are designated
as difficult to inspect, an explanation of why the equipment is
difficult to inspect, and the plan for inspecting the equipment.
(3) For each vapor collection system or closed vent system that
contains bypass lines that could divert a vent stream away from the
control device
[[Page 329]]
and to the atmosphere, the owner or operator shall keep a record of the
information specified in either paragraph (i)(3)(i) or (i)(3)(ii) of
this section.
(i) Hourly records of whether the flow indicator specified under
paragraph (f)(1) of this section was operating and whether a diversion
was detected at any time during the hour, as well as records of the
times of all periods when the vent stream is diverted from the control
device or the flow indicator is not operating.
(ii) Where a seal mechanism is used to comply with paragraph (f)(2)
of this section, hourly records of flow are not required. In such cases,
the owner or operator shall record whether the monthly visual inspection
of the seals or closure mechanisms has been done, and shall record the
occurrence of all periods when the seal mechanism is broken, the bypass
line valve position has changed, or the key for a lock-and-key type
configuration has been checked out, and records of any car-seal that has
broken.
(4) For each inspection during which a leak is detected, a record of
the information specified in paragraphs (i)(4)(i) through (i)(4)(viii)

this subpart;
[[Page 330]]
(c) The item of equipment is part of a chemical manufacturing
process unit that meets the criteria of Sec. 63.100(b) of subpart F of
this part;
(d) The item of equipment is controlled less stringently than in
table 35 and is not listed in Sec. 63.100(f) of subpart F of this part,
and the item of equipment is not otherwise exempt from controls by the

[62 FR 2776, Jan. 17, 1997]
Sec. 63.150 Emissions averaging provisions.
(a) This section applies to owners or operators of existing sources
who seek to comply with the emission standard in Sec. 63.112(a) of this
subpart by using emissions averaging according to Sec. 63.112(f) of
this subpart rather than following the provisions of Sec. Sec. 63.113
through 63.148 of this subpart. Notwithstanding the definition of
process vent in Sec. 63.101 and the sampling site designation in Sec.
63.115(a), for purposes of this section the location of a process vent
shall be defined, and the characteristics of its gas stream shall be
determined, consistent with paragraph (g)(2)(i) of this section.
(b) Unless an operating permit application has been submitted, the
owner or operator shall develop and submit for approval an
Implementation Plan containing all of the information required in Sec.
63.151(d) of this subpart for all points to be included in an emissions
average. The Implementation Plan or operating permit application shall
identify all emission points to be included in the emissions average.
This must include any Group 1 emission points to which the reference
control technology (defined in Sec. 63.111 of this subpart) is not
applied and all other emission points being controlled as part of the
average.
(c) The following emission points can be used to generate emissions
averaging credits, if control was applied after November 15, 1990 and if
sufficient information is available to determine the appropriate value
of credits for the emission point:
(1) Group 2 emission points.
(2) Group 1 emission points that are controlled by a technology that
the Administrator or permitting authority agrees has a higher nominal
efficiency than the reference control technology. Information on the
nominal efficiencies for such technologies must be
[[Page 331]]
submitted and approved as provided in paragraph (i) of this section.
(3) Emission points from which emissions are reduced by pollution
prevention measures. Percent reductions for pollution prevention
measures shall be determined as specified in paragraph (j) of this
section.
(i) For a Group 1 emission point, the pollution prevention measure
must reduce emissions more than the reference control technology would
have had the reference control technology been applied to the emission
point instead of the pollution prevention measure except as provided in
paragraph (c)(3)(ii) of this section.
(ii) If a pollution prevention measure is used in conjunction with
other controls for a Group 1 emission point, the pollution prevention
measure alone does not have to reduce emissions more than the reference
control technology, but the combination of the pollution prevention
measure and other controls must reduce emissions more than the reference
control technology would have had it been applied instead.
(d) The following emission points cannot be used to generate
emissions averaging credits:
(1) Emission points already controlled on or before November 15,
1990, unless the level of control is increased after November 15, 1990,
in which case credit will be allowed only for the increase in control
after November 15, 1990.
(2) Group 1 emission points that are controlled by a reference
control technology, unless the reference control technology has been
approved for use in a different manner and a higher nominal efficiency
has been assigned according to the procedures in paragraph (i) of this
section. For example, it is not allowable to claim that an internal
floating roof meeting the specifications of Sec. 63.119(b) of this
subpart applied to a storage vessel is achieving greater than 95 percent
control.
(3) Emission points on shut-down process units. Process units that
are shut down cannot be used to generate credits or debits.
(4) Wastewater that is not process wastewater or wastewater streams
treated in biological treatment units. These two types of wastewater
cannot be used to generate credits or debits. For the purposes of this
section, the terms wastewater and wastewater stream are used to mean
process wastewater.
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart, 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.
(e) For all points included in an emissions average, the owner or
operator shall:
(1) Calculate and record monthly debits for all Group 1 emission
points that are controlled to a level less stringent than the reference
control technology for those emission points. Equations in paragraph (g)
of this section shall be used to calculate debits.
(2) Calculate and record monthly credits for all Group 1 or Group 2
emission points that are overcontrolled to compensate for the debits.
Equations in paragraph (h) of this section shall be used to calculate
credits. Emission points and controls that meet the criteria of
paragraph (c) of this section may be included in the credit calculation,
whereas those described in paragraph (d) of this section shall not be
included.
(3) Demonstrate that annual credits calculated according to
paragraph (h) of this section are greater than or equal to debits
calculated for the same annual compliance period according to paragraph
(g) of this section.
(i) The owner or operator may choose to include more than the
required number of credit-generating emission points in an average in
order to increase the likelihood of being in compliance.
[[Page 332]]
(ii) The initial demonstration in the Implementation Plan or
operating permit application that credit-generating emission points will
be capable of generating sufficient credits to offset the debits from
the debit-generating emission points must be made under representative
operating conditions. After the compliance date, actual operating data
will be used for all debit and credit calculations.
(4) Demonstrate that debits calculated for a quarterly (3-month)
period according to paragraph (g) of this section are not more than 1.30
times the credits for the same period calculated according to paragraph
(h) of this section. Compliance for the quarter shall be determined
based on the ratio of credits and debits from that quarter, with 30
percent more debits than credits allowed on a quarterly basis.
(5) Record and report quarterly and annual credits and debits in the
Periodic Reports as specified in Sec. 63.152(c) of this subpart. Every
fourth Periodic Report shall include a certification of compliance with
the emissions averaging provisions as required by Sec.
63.152(c)(5)(iv)(B) of this subpart.
(f) Debits and credits shall be calculated in accordance with the
methods and procedures specified in paragraphs (g) and (h) of this
section, respectively, and shall not include emissions from the
following:
(1) More than 20 individual Group 1 or Group 2 emission points.
Where pollution prevention measures (as specified in paragraph (j)(1) of
this section) are used to control emission points to be included in an
emissions average, no more than 25 emission points may be included in
the average. For example, if two emission points to be included in an
emissions average are controlled by pollution prevention measures, the
average may include up to 22 emission points.
(2) Periods of start-up, shutdown, and malfunction as described in
the source's start-up, shutdown, and malfunction plan required by Sec.
63.6(e)(3) of subpart A of this part.
(3) Periods of monitoring excursions as defined in Sec.
63.152(c)(2)(ii)(A) of this subpart. For these periods, the calculation
of monthly credits and debits shall be adjusted as specified in
paragraphs (f)(3)(i) through (f)(3)(iii) of this section.
(i) No credits would be assigned to the credit-generating emission
point.
(ii) Maximum debits would be assigned to the debit-generating
emission point.
(iii) The owner or operator may demonstrate to the Administrator
that full or partial credits or debits should be assigned using the
procedures in paragraph (l) of this section.
(g) Debits are generated by the difference between the actual
emissions from a Group 1 emission point that is uncontrolled or is
controlled to a level less stringent than the reference control
technology, and the emissions allowed for the Group 1 emission point.
Debits shall be calculated as follows:
(1) The overall equation for calculating source-wide debits is:
[GRAPHIC] [TIFF OMITTED] TR22AP94.245
where:
Debits and all terms of the equation are in units of megagrams per
month, and
[[Page 333]]
EPViACTUAL = Emissions from each Group 1 process vent i that
is uncontrolled or is controlled to a level less stringent
than the reference control technology. This is calculated
according to paragraph (g)(2) of this section.
(0.02) EPViu = Emissions from each Group 1 vent i if the
reference control technology had been applied to the
uncontrolled emissions, calculated according to paragraph
(g)(2) of this section.
ESiACTUAL = Emissions from each Group 1 storage vessel i that
is uncontrolled or is controlled to a level less stringent
than the reference control technology. This is calculated
according to paragraph (g)(3) of this section.

the reference control technology had been applied to the
uncontrolled emissions, calculated according to paragraph
(g)(3) of this section.
ETRiACTUAL = Emissions from each Group 1 transfer rack i that
is uncontrolled or is controlled to a level less stringent
than the reference control technology. This is calculated
according to paragraph (g)(4) of this section.

the reference control technology had been applied to the
uncontrolled emissions, calculated according to paragraph
(g)(4) of this section.

that is uncontrolled or is controlled to a level less
stringent than the reference control technology. This is
calculated according to paragraph (g)(5) of this section.
EWWic = Emissions from each Group 1 wastewater stream i if
the reference control technology had been applied to the
uncontrolled emissions. This is calculated according to
paragraph (g)(5) of this section.
n = The number of emission points being included in the emissions
average. The value of n is not necessarily the same for
process vents, storage vessels, transfer racks, and
wastewater.
(2) Emissions from process vents shall be calculated according to
paragraphs (g)(2)(i) through (iii) of this section.
(i) The location of a process vent shall be defined, and the
characteristics of its gas stream shall be determined at a point that
meets the conditions in either paragraph (g)(2)(i)(A) or (B) of this
section and the conditions in paragraphs (g)(2)(i)(C) through (E) of
this section.
(A) The point is after the final recovery device (if any recovery
devices are present).
(B) If a gas stream included in an emissions average is combined
with one or more other gas streams after a final recovery device (if any
recovery devices are present), then for each gas stream, the point is at
a representative point after any final recovery device and as near as
feasible to, but before, the point of combination of the gas streams.
(C) The point is before any control device (for process vents,
recovery devices shall not be considered control devices).
(D) The point is before discharge to the atmosphere.
(E) The measurement site for determination of the characteristics of
the gas stream was selected using Method 1 or 1A of 40 CFR part 60,
appendix A.
(ii) The following equation shall be used for each process vent i to
calculate EPViu:
[GRAPHIC] [TIFF OMITTED] TR22AP94.246
where:
EPViu = Uncontrolled process vent emission rate from process
vent i, megagrams per month.
Q = Vent stream flow rate, dry standard cubic meters per minute,
measured using Method 2, 2A, 2C, or 2D of part 60, appendix A,
as appropriate.

the vent, hours per month.
Cj = Concentration, parts per million by volume, dry basis, of organic
HAP j as measured by Method 18 of part 60, appendix A.
Mj = Molecular weight of organic HAP j, gram per gram-mole.

determined during a performance test conducted under representative
operating conditions. The values of Q, Cj, and Mj
shall be established in the Notification of Compliance Status and must
be updated as provided in paragraph (g)(2)(ii)(B) of this section.
(B) If there is a change in capacity utilization other than a change
in monthly operating hours, or if any other change is made to the
process or
[[Page 334]]
product recovery equipment or operation such that the previously
measured values of Q, Cj, and Mj are no longer
representative, a new performance test shall be conducted to determine
new representative values of Q, Cj, and Mj. These
new values shall be used to calculate debits and credits from the time
of the change forward, and the new values shall be reported in the next
Periodic Report.
(iii) The following procedures and equations shall be used to
calculate EPViACTUAL:
(A) If the vent is not controlled by a control device or pollution
prevention measure, EPViACTUAL = EPViu, where
EPViu is calculated according to the procedures in paragraphs
(g)(2)(i) and (g)(2)(ii) of this section.
(B) If the vent is controlled using a control device or a pollution
prevention measure achieving less than 98-percent reduction,
[GRAPHIC] [TIFF OMITTED] TR22AP94.247
(1) The percent reduction shall be measured according to the
procedures in Sec. 63.116 of this subpart if a combustion control
device is used. For a flare meeting the criteria in Sec. 63.116(a) of
this subpart, or a boiler or process heater meeting the criteria in
Sec. 63.116(b) of this subpart, the percent reduction shall be 98
percent. If a non-combustion control device is used, percent reduction
shall be demonstrated by a performance test at the inlet and outlet of
the device, or, if testing is not feasible, by a control design
evaluation and documented engineering calculations.
(2) For determining debits from Group 1 process vents, recovery
devices shall not be considered control devices and cannot be assigned a
percent reduction in calculating EPViACTUAL. The sampling
site for measurement of uncontrolled emissions is after the final
recovery device. However, as provided in Sec. 63.113(a)(3), a Group 1
process vent may add sufficient recovery to raise the TRE index value
above 1.0, thereby becoming a Group 2 process vent.
(3) Procedures for calculating the percent reduction of pollution
prevention measures are specified in paragraph (j) of this section.
(3) Emissions from storage vessels shall be calculated as follows:
(i) The following equation shall be used for each storage vessel i
to calculate ESiu:
[GRAPHIC] [TIFF OMITTED] TR22AP94.248
where:
ESiu = Uncontrolled emissions, defined as emissions from a
fixed roof vessel having identical dimensions and vessel color
as vessel i, megagrams per month.
LB = Breathing loss emissions, megagrams per year, calculated

pound-mole.
[[Page 335]]
PA = Average atmospheric pressure, pounds per square inch
absolute.
P = True vapor pressure of the HAP at liquid storage temperature, pounds
per square inch absolute. See table 21 of this subpart.
D = Tank diameter, feet.
H = Average vapor space height, feet. Use vessel-specific values or an
assumed value of one-half the height.
[Delta] T = Average ambient diurnal temperature change, [deg]F. A
typical value of 20 [deg]F may be used.
Fp = Paint factor, dimensionless, from table 22 of this
subpart; use Fp = 1 for vessels located indoors.
C = Adjustment factor for small diameter tanks, dimensionless; use C = 1
for diameter =30 feet; use C = 0.0771D - 0.0013D\2\
- 0.1334 for diameter <30 feet.
KC = Product factor, dimensionless. Use 1.0 for organic
HAP's.
(B) Working losses shall be calculated using the following equation:
LW = 1.089 x 10-8 Mv (P)(V)(N)
(KN) (KC)
where:
V = Tank capacity, gallon.
N = Number of turnovers per year.

1990, was managed according to the requirements of Sec. Sec. 63.133
through 63.137 of this subpart, as applicable, and was uncontrolled or
controlled to a level less stringent than the reference control
technology.
(iv) For Group 2 wastewater streams that are managed according to
the requirements of Sec. Sec. 63.133 through 63.137 of this subpart, as
applicable, EWW2iACTUAL shall be calculated as follows:
(A) EWW2iACTUAL shall be calculated according to the
equation for EWWiACTUAL in paragraph (g)(5)(iii) of this
section for each Group 2 wastewater stream i that is controlled to a
level less stringent than, or equivalent to, the reference control
technology.
(B) EWW2iACTUAL shall be calculated according to the
procedures for calculating EWW1iACTUAL in paragraph (h)(5)(v)
of this section for each Group 2 wastewater stream that is controlled to

subpart, but the vapor stream(s) vented from the treatment process(es)
are controlled using a device with an approved nominal efficiency
greater than 95 percent, the following equation shall be used. All terms
other than nominal efficiency are as defined and determined in paragraph
(g)(5) of this section.
[[Page 346]]
[GRAPHIC] [TIFF OMITTED] TR26AP99.009
(C) If the Group 1 wastewater stream i is controlled using a
treatment process or series of treatment processes with an approved
nominal reduction efficiency in the table 9 HAP concentration greater
than that of the design steam stripper specified in Sec. 63.138(d) of
this subpart, and the vapor stream(s) vented from the treatment process
are controlled using a device with an approved nominal efficiency
greater than 95 percent, the following equation shall be used. All terms
other than nominal efficiency are as defined and determined in paragraph
(g)(5) of this section.
[GRAPHIC] [TIFF OMITTED] TR26AP99.010
(i) The following procedures shall be followed to establish nominal
efficiencies. The procedures in paragraphs (i)(1) through (i)(6) of this
section shall be followed for control technologies that are different in
use or design from the reference control technologies and achieve
greater percent reductions than the percent efficiencies assigned to the
reference control technologies in Sec. 63.111 of this subpart.
(1) In those cases where the owner or operator is seeking permission
to take credit for use of a control technology that is different in use
or design from the reference control technology, and the different
control technology will be used in more than three applications at a
single plant-site, the owner or operator shall submit the information
specified in paragraphs (i)(1)(i) through (i)(1)(iv) of this section to
the Director of the EPA Office of Air Quality Planning and Standards in
writing:
(i) Emission stream characteristics of each emission point to which
the control technology is or will be applied including the kind of
emission point, flow, organic HAP concentration, and all other stream
characteristics necessary to design the control technology or determine
its performance.
(ii) Description of the control technology including design
specifications.
(iii) Documentation demonstrating to the Administrator's
satisfaction the control efficiency of the control technology. This may
include performance test data collected using an appropriate EPA method
or any other method validated according to Method 301 of appendix A of
this part. If it is infeasible to obtain test data, documentation may
include a design evaluation and calculations. The engineering basis of
the calculation procedures and all inputs and assumptions made in the
calculations shall be documented.
(iv) A description of the parameter or parameters to be monitored to
ensure that the control technology will be operated in conformance with
its design and an explanation of the criteria used for selection of that
parameter (or parameters).
(2) The Administrator shall determine within 120 calendar days
whether an application presents sufficient information to determine
nominal efficiency. The Administrator reserves the
[[Page 347]]
right to request specific data in addition to the items listed in
paragraph (i)(1) of this section.
(3) The Administrator shall determine within 120 calendar days of
the submittal of sufficient data whether a control technology shall have
a nominal efficiency and the level of that nominal efficiency. If, in
the Administrator's judgment, the control technology achieves a level of
emission reduction greater than the reference control technology for a
particular kind of emission point, the Administrator will publish a
Federal Register notice establishing a nominal efficiency for the
control technology.
(4) The Administrator may condition permission to take emission
credits for use of the control technology on requirements that may be
necessary to ensure operation and maintenance to achieve the specified
nominal efficiency.
(5) In those cases where the owner or operator is seeking permission
to take credit for use of a control technology that is different in use
or design from the reference control technology and the different
control technology will be used in no more than three applications at a
single plant site, the information listed in paragraphs (i)(1)(i)
through (i)(1)(iv) can be submitted to the permitting authority for the
source for approval instead of the Administrator.
(i) In these instances, use and conditions for use of the control
technology can be approved by the permitting authority as part of an
operating permit application or modification. The permitting authority
shall follow the procedures specified in paragraphs (i)(2) through
(i)(4) of this section except that, in these instances, a Federal
Register notice is not required to establish the nominal efficiency for
the different technology.
(ii) If, in reviewing the application, the permitting authority
believes the control technology has broad applicability for use by other
sources, the permitting authority shall submit the information provided
in the application to the Director of the EPA Office of Air Quality
Planning and Standards. The Administrator shall review the technology
for broad applicability and may publish a Federal Register notice;
however, this review shall not affect the permitting authority's
approval of the nominal efficiency of the control technology for the
specific application.
(6) If, in reviewing an application for a control technology for an
emission point, the Administrator or permitting authority determines the
control technology is not different in use or design from the reference
control technology, the Administrator or permitting authority shall deny
the application.
(j) The following procedures shall be used for calculating the
efficiency (percent reduction) of pollution prevention measures:
(1) A pollution prevention measure is any practice which meets the
criteria of paragraphs (j)(1)(i) and (j)(1)(ii) of this section.
(i) A pollution prevention measure is any practice that results in a
lesser quantity of organic HAP emissions per unit of product released to
the atmosphere prior to out-of-process recycling, treatment, or control
of emissions, while the same product is produced.
(ii) Pollution prevention measures may include: substitution of
feedstocks that reduce HAP emissions; alterations to the production
process to reduce the volume of materials released to the environment;
equipment modifications; housekeeping measures; and in-process recycling
that returns waste materials directly to production as raw materials.
Production cutbacks do not qualify as pollution prevention.
(2) The emission reduction efficiency of pollution prevention
measures implemented after November 15, 1990, can be used in calculating
the actual emissions from an emission point in the debit and credit
equations in paragraphs (g) and (h) of this section. When the term
``organic HAP'' is used in Sec. 63.150(j)(2) in reference to wastewater
emission points, the term ``table 9 HAP'' shall apply for the purposes
of this paragraph.
(i) For pollution prevention measures, the percent reduction used in
the equations in paragraphs (g)(2) through (g)(5) of this section and
paragraphs (h)(2) through (h)(5) of this section is the percent
difference between the monthly organic HAP emissions for each emission
point after the pollution
[[Page 348]]
prevention measure for the most recent month versus monthly emissions
from the same emission point before the pollution prevention measure,
adjusted by the volume of product produced during the two monthly
periods.
(ii) The following equation shall be used to calculate the percent
reduction of a pollution prevention measure for each emission point.
[GRAPHIC] [TIFF OMITTED] TR22AP94.290
where:
Percent reduction = Efficiency of pollution prevention measure (percent
organic HAP reduction).
EB = Monthly emissions before the pollution prevention
measure, megagrams per month, determined as specified in
paragraphs (j)(2)(ii)(A), (j)(2)(ii)(B), and (j)(2)(ii)(C) of
this section.
Epp = Monthly emissions after the pollution prevention
measure, megagrams per month, as determined for the most
recent month, determined as specified in paragraphs
(j)(2)(ii)(D) or (j)(2)(ii)(E) of this section.
PB = Monthly production before the pollution prevention
measure, megagrams per month, during the same period over
which EB is calculated.
Ppp = Monthly production after the pollution prevention
measure, megagrams per month, as determined for the most
recent month.
(A) The monthly emissions before the pollution prevention measure,
EB, shall be determined in a manner consistent with the
equations and procedures in paragraphs (g)(2), (g)(3), and (g)(4) of
this section for process vents, storage vessels, and transfer
operations.
(B) For wastewater, EB shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR26AP99.011
Where:
n = Number of wastewater streams.
QBi = Average flow rate for wastewater stream i before the
pollution prevention measure, defined and determined according
to paragraph (g)(5)(i) of this section, liters per minute,
before implementation of the pollution prevention measure.
HBi = Number of hours per month that wastewater stream i was
discharged before the pollution prevention measure, hours per
month.
s = Total number of table 9 HAP in wastewater stream i.
Fem = Fraction emitted of table 9 HAP m in wastewater of this
subpart, dimensionless.
HAPBim = Average concentration of table 9 HAP m in wastewater
stream i, defined and determined according to paragraph
(g)(5)(i) of this section, before the pollution prevention
measure, parts per million by weight, as measured before the
implementation of the pollution measure.
(C) If the pollution prevention measure was implemented prior to
April 22, 1994, records may be used to determine EB.
(D) The monthly emissions after the pollution prevention measure,
Epp, may be determined during a performance test or by a
design evaluation and documented engineering calculations. Once an
emissions-to-production ratio has been established, the ratio can be
used to estimate monthly emissions from monthly production records.
(E) For wastewater, Epp shall be calculated using the
following equation:
[GRAPHIC] [TIFF OMITTED] TR22AP94.292
[[Page 349]]
where n, Qppi, Hppi, s, Fem, and
HAPppim are defined and determined as described in paragraph
(j)(2)(ii)(B) of this section except that Qppi,
Hppi, and HAPppim shall be determined after the
pollution prevention measure has been implemented.
(iii) All equations, calculations, test procedures, test results,
and other information used to determine the percent reduction achieved
by a pollution prevention measure for each emission point shall be fully
documented.
(iv) The same pollution prevention measure may reduce emissions from
multiple emission points. In such cases, the percent reduction in
emissions for each emission point must be calculated.
(v) For the purposes of the equations in paragraphs (h)(2) through
(h)(5) of this section, used to calculate credits for emission points
controlled more stringently than the reference control technology, the
nominal efficiency of a pollution prevention measure is equivalent to
the percent reduction of the pollution prevention measure. When a
pollution prevention measure is used, the owner or operator of a source
is not required to apply to the Administrator for a nominal efficiency
and is not subject to paragraph (i) of this section.
(k) The owner or operator must demonstrate that the emissions from
the emission points proposed to be included in the average will not
result in greater hazard or, at the option of the operating permit
authority, greater risk to human health or the environment than if the
emission points were controlled according to the provisions in
Sec. Sec. 63.113 through 63.148.
(1) This demonstration of hazard or risk equivalency shall be made
to the satisfaction of the operating permit authority.
(i) The Administrator may require owners and operators to use
specific methodologies and procedures for making a hazard or risk
determination.
(ii) The demonstration and approval of hazard or risk equivalency
shall be made according to any guidance that the Administrator makes
available for use.
(2) Owners and operators shall provide documentation demonstrating
the hazard or risk equivalency of their proposed emissions average in
their operating permit application or in their Implementation Plan if an
operating permit application has not yet been submitted.
(3) An emissions averaging plan that does not demonstrate hazard or
risk equivalency to the satisfaction of the Administrator shall not be
approved. The Administrator may require such adjustments to the
emissions averaging plan as are necessary in order to ensure that the
average will not result in greater hazard or risk to human health or the
environment than would result if the emission points were controlled
according to Sec. Sec. 63.113 through 63.148 of this subpart.
(4) A hazard or risk equivalency demonstration must:
(i) Be a quantitative, bona fide chemical hazard or risk assessment;
(ii) Account for differences in chemical hazard or risk to human
health or the environment; and
(iii) Meet any requirements set by the Administrator for such
demonstrations.
(l) For periods of excursions, an owner or operator may request that
the provisions of paragraphs (l)(1) through (l)(4) of this section be
followed instead of the procedures in paragraphs (f)(3)(i) and
(f)(3)(ii) of this section.
(1) The owner or operator shall notify the Administrator of
excursions in the Periodic Reports as required in Sec. 63.152 of this
subpart.
(2) The owner or operator shall demonstrate that other types of
monitoring data or engineering calculations are appropriate to establish
that the control device for the emission point was operating in such a
fashion to warrant assigning full or partial credits and debits. This
demonstration shall be made to the Administrator's satisfaction, and the
Administrator may establish procedures of demonstrating compliance that
are acceptable.
(3) The owner or operator shall provide documentation of the
excursion and the other type of monitoring data or engineering
calculations to be used to demonstrate that the control device for the
emission point was operating in such a fashion to warrant assigning full
or partial credits and debits.
[[Page 350]]
(4) The Administrator may assign full or partial credit and debits
upon review of the information provided.
(m) For each Group 1 or Group 2 emission point included in an
emissions average, the owner or operator shall perform testing,
monitoring, recordkeeping, and reporting equivalent to that required for
Group 1 emission points complying with Sec. Sec. 63.113 through 63.148
of this subpart. The specific requirements for process vents, storage
vessels, transfer racks, and wastewater are identified in paragraphs

outside their established ranges.
(i) For each parameter or parameters required to be monitored for a
control device, the owner or operator shall establish a range of
parameter values to ensure that the device is being applied, operated
and maintained properly. As specified in paragraph (b)(2) of this
section, these parameter values and the definition of an operating day
shall be approved as part of and incorporated into the source's
Notification of Compliance Status or operating permit, as appropriate.
(ii) The parameter monitoring data for Group 1 emission points and
emission points included in emissions averages that are required to
perform continuous monitoring shall be used to determine compliance with
the required operating conditions for the monitored control devices or
recovery devices. For each excursion, except for excused excursions, the
owner or operator shall be deemed to have failed to have applied the
control in a manner that achieves the required operating conditions.
(A) An excursion means any of the three cases listed in paragraph
(c)(2)(ii)(A)(1), (c)(2)(ii)(A)(2), or (c)(2)(ii)(A)(3) of this section.
For a control device or recovery device where multiple parameters are
monitored, if one or more of the parameters meets the excursion criteria
in paragraph (c)(2)(ii)(A)(1), (c)(2)(ii)(A)(2), or (c)(2)(ii)(A)(3) of
this section, this is considered a single excursion for the control
device or recovery device.
(1) When the daily average value of one or more monitored parameters
is outside the permitted range.
(2) When the period of control device or recovery device operation
is 4 hours or greater in an operating day and monitoring data are
insufficient to constitute a valid hour of data for at least 75 percent
of the operating hours.
(3) When the period of control device or recovery device operation
is less than 4 hours in an operating day and more than one of the hours
during the period of operation does not constitute
[[Page 359]]
a valid hour of data due to insufficient monitoring data.
(4) Monitoring data are insufficient to constitute a valid hour of
data, as used in paragraphs (c)(2)(ii)(A)(2) and (c)(2)(ii)(A)(3) of
this section, if measured values are unavailable for any of the 15-
minute periods within the hour. For data compression systems approved
under Sec. 63.151(g)(4), monitoring data are insufficient to calculate
a valid hour of data if there are less than 4 data values recorded
during the hour.
(B) The number of excused excursions for each control device or
recovery device for each semiannual period is specified in paragraphs
(c)(2)(ii)(B)(1) through (c)(2)(ii)(B)(6) of this section. This
paragraph applies to sources required to submit Periodic Reports
semiannually or quarterly. The first semiannual period is the 6-month
period starting the date the Notification of Compliance Status is due.

(2) For the second semiannual period--five excused excursions.
(3) For the third semiannual period--four excused excursions.
(4) For the fourth semiannual period--three excused excursions.
(5) For the fifth semiannual period--two excused excursions.
(6) For the sixth and all subsequent semiannual periods--one excused
excursion.
(C) A monitored parameter that is outside its established range or
monitoring data that are not collected are excursions. However, if the
conditions in paragraph (c)(2)(ii)(C)(1) or (c)(2)(ii)(C)(2) of this
section are met, these excursions are not violations and do not count
toward the number of excused excursions for determining compliance.
(1) Periods of startup, shutdown, or malfunction. During periods of
startup, shutdown, or malfunction when the source is operated during
such periods in accordance with Sec. 63.102(a)(4).
(2) Periods of nonoperation. During periods of nonoperation of the
chemical manufacturing process unit, or portion thereof, that results in
cessation of the emissions to which the monitoring applies.
(D) Nothing in paragraph (c)(2)(ii) of this section shall be
construed to allow or excuse a monitoring parameter excursion caused by
any activity that violates other applicable provisions of subpart A, F,
or G of this part.
(E) Paragraph (c)(2)(ii) of this section, except paragraph
(c)(2)(ii)(C) of this section, shall apply only to emission points and
control devices or recovery devices for which continuous monitoring is
required by Sec. Sec. 63.113 through 63.150.
(iii) Periodic Reports shall include the daily average values of
monitored parameters for both excused and unexcused excursions, as
defined in paragraph (c)(2)(ii)(A) of this section. For excursions
caused by lack of monitoring data, the duration of periods when
monitoring data were not collected shall be specified.
(iv) The provisions of paragraphs (c)(2), (c)(2)(i), (c)(2)(ii), and
(c)(2)(iii) of this section do not apply to any storage vessel for which
the owner or operator is not required, by the applicable monitoring plan
established under Sec. 63.120(d)(2), to keep continuous records. If
continuous records are required, the owner or operator shall specify, in
the monitoring plan, whether the provisions of paragraphs (c)(2),
(c)(2)(i), (c)(2)(ii), and (c)(2)(iii) of this section apply.
(3) If any performance tests are reported in a Periodic Report, the
following information shall be included:
(i) One complete test report shall be submitted for each test method
used for a particular kind of emission point tested. A complete test
report shall contain the information specified in paragraph (b)(1)(ii)
of this section.
(ii) For additional tests performed for the same kind of emission
point using the same method, results and any other information required
in Sec. 63.117 for process vents, Sec. 63.129 for transfer, and Sec.
63.146 for process wastewater shall be submitted, but a complete test
report is not required.

Sec. Sec. 63.118, 63.130, 63.147, 63.150, or other sections of this
subpart shall keep records as specified in paragraphs (f)(1) through
(f)(7) of this section, unless an alternative recordkeeping system has
been requested and approved under Sec. 63.151(f) or (g) or Sec.
63.152(e) or under Sec. 63.8(f) of subpart A of this part, and except
as provided in paragraph (c)(2)(ii)(C) of this section or in paragraph
(g) of this section. If a monitoring plan for storage vessels pursuant
to Sec. 63.120(d)(2)(i)
[[Page 362]]
requires continuous records, the monitoring plan shall specify which
provisions, if any, of paragraphs (f)(1) through (f)(7) of this section
apply.
(1) The monitoring system shall measure data values at least once
every 15 minutes.
(2) The owner or operator shall record either:
(i) Each measured data value; or
(ii) Block average values for 15-minute or shorter periods
calculated from all measured data values during each period or at least
one measured data value per minute if measured more frequently than once
per minute.
(3) If the daily average value of a monitored parameter for a given
operating day is within the range established in the Notification of
Compliance Status or operating permit, the owner or operator shall
either:
(i) Retain block hourly average values for that operating day for 5
years and discard, at or after the end of that operating day, the 15-
minute or more frequent average values and readings recorded under
paragraph (f)(2) of this section; or
(ii) Retain the data recorded in paragraph (f)(2) of this section
for 5 years.
(4) If the daily average value of a monitored parameter for a given
operating day is outside the range established in the Notification of
Compliance Status or operating permit, the owner or operator shall
retain the data recorded that operating day under paragraph (f)(2) of
this section for 5 years.
(5) Daily average values of each continuously monitored parameter
shall be calculated for each operating day, and retained for 5 years,
except as specified in paragraphs (f)(6) and (f)(7) of this section.
(i) The daily average shall be calculated as the average of all
values for a monitored parameter recorded during the operating day. The
average shall cover a 24-hour period if operation is continuous, or the
number of hours of operation per operating day if operation is not
continuous.
(ii) The operating day shall be the period defined in the operating
permit or the Notification of Compliance Status. It may be from midnight
to midnight or another daily period.
(6) If all recorded values for a monitored parameter during an
operating day are within the range established in the Notification of
Compliance Status or operating permit, the owner or operator may record
that all values were within the range and retain this record for 5 years
rather than calculating and recording a daily average for that operating
day. For these operating days, the records required in paragraph (f)(3)
of this section shall also be retained for 5 years.
(7) Monitoring data recorded during periods identified in paragraphs
(f)(7)(i) through (f)(7)(v) of this section shall not be included in any
average computed under this subpart. Records shall be kept of the times
and durations of all such periods and any other periods during process
or control device operation when monitors are not operating.
(i) Monitoring system breakdowns, repairs, calibration checks, and
zero (low-level) and high-level adjustments;
(ii) Start-ups;
(iii) Shutdowns;
(iv) Malfunctions;
(v) Periods of non-operation of the chemical manufacturing process
unit (or portion thereof), resulting in cessation of the emissions to
which the monitoring applies.
(g) For any parameter with respect to any item of equipment, the
owner or operator may implement the recordkeeping requirements in
paragraph (g)(1) or (g)(2) of this section as alternatives to the
continuous operating parameter monitoring and recordkeeping provisions
listed in Sec. Sec. 63.114, 63.117, and 63.118 for process vents,
Sec. Sec. 63.127, 63.129, and 63.130 for transfer operations,
Sec. Sec. 63.143, 63.146, and 63.147 for wastewater, and/or Sec.
63.152(f), except that Sec. 63.152(f)(7) shall apply. The owner or
operator shall retain each record required by paragraph (g)(1) or (g)(2)
of this section as provided in Sec. 63.103(c) of subpart F of this
part, except as provided otherwise in paragraph (g)(1) or (g)(2) of this
section.
(1) The owner or operator may retain only the daily average value,
and is not required to retain more frequent monitored operating
parameter values, for a monitored parameter with respect to an item of
equipment, if the requirements of paragraphs (g)(1)(i) through
[[Page 363]]
(g)(1)(vi) of this section are met. An owner or operator electing to
comply with the requirements of paragraph (g)(1) of this section shall
notify the Administrator in the Notification of Compliance Status or, if
the Notification of Compliance Status has already been submitted, in the
periodic report immediately preceding implementation of the requirements
of paragraph (g)(1) of this section.
(i) The monitoring system is capable of detecting unrealistic or
impossible data during periods of operation other than startups,
shutdowns, or malfunctions (e.g., a temperature reading of -200 [deg]C
on a boiler), and will alert the operator by alarm or other means. The
owner or operator shall record the occurrence. All instances of the
alarm or other alert in an operating day constitute a single occurrence.
(ii) The monitoring system generates, updated at least hourly
throughout each operating day, a running average of the monitoring
values that have been obtained during that operating day, and the
capability to observe this average is readily available to the
Administrator on-site during the operating day. The owner or operator
shall record the occurrence of any period meeting the criteria in
paragraphs (g)(1)(ii)(A) through (g)(1)(iii)(C) of this section. All
instances in an operating day constitute a single occurrence.
(A) The running average is above the maximum or below the minimum
established limits;
(B) The running average is based on at least 6 1-hour average
values; and
(C) The running average reflects a period of operation other than a
startup, shutdown, or malfunction.
(iii) The monitoring system is capable of detecting unchanging data
during periods of operation other than startups, shutdowns, or
malfunctions, except in circumstances where the presence of unchanging
data is the expected operating condition based on past experience (e.g.,
pH in some scrubbers), and will alert the operator by alarm or other
means. The owner or operator shall record the occurrence. All instances
of the alarm or other alert in an operating day constitute a single
occurrence.
(iv) The monitoring system will alert the owner or operator by an
alarm or other means, if the running average parameter value calculated
under paragraph (g)(1)(ii) of this section reaches a set point that is
appropriately related to the established limit for the parameter that is
being monitored.
(v) The owner or operator shall verify the proper functioning of the
monitoring system, including its ability to comply with the requirements
of paragraph (g)(1) of this section, at the times specified in
paragraphs (g)(1)(v)(A) through (g)(1)(v)(C) of this section. The owner
or operator shall document that the required verifications occurred.
(A) Upon initial installation.
(B) Annually after initial installation.
(C) After any change to the programming or equipment constituting
the monitoring system, which might reasonably be expected to alter the
monitoring system's ability to comply with the requirements of this
section.
(vi) The owner or operator shall retain the records identified in
paragraphs (g)(1)(vi) (A) through (C) of this section.
(A) Identification of each parameter, for each item of equipment,
for which the owner or operator has elected to comply with the
requirements of paragraph (g) of this section.
(B) A description of the applicable monitoring system(s), and of how
compliance will be achieved with each requirement of paragraph (g)(1)(i)
through (g)(1)(v) of this section. The description shall identify the
location and format (e.g., on-line storage; log entries) for each
required record. If the description changes, the owner or operator shall
retain both the current and the most recent superseded description. The
description, and the most recent superseded description, shall be
retained as provided in Sec. 63.103(c) of subpart F of this part,
except as provided in paragraph (g)(1)(vi)(D) of this section.
(C) A description, and the date, of any change to the monitoring
system that would reasonably be expected to affect its ability to comply
with the requirements of paragraph (g)(1) of this section.
[[Page 364]]
(D) Owners and operators subject to paragraph (g)(1)(vi)(B) of this
section shall retain the current description of the monitoring system as
long as the description is current, but not less than 5 years from the
date of its creation. The current description shall, at all times, be
retained on-site or be accessible from a central location by computer or
other means that provides access within 2 hours after a request. The
owner or operator shall retain the most recent superseded description at
least until 5 years from the date of its creation. The superseded
description shall be retained on-site (or accessible from a central
location by computer that provides access within 2 hours after a
request) at least 6 months after its creation. Thereafter, the
superseded description may be stored off-site.
(2) If an owner or operator has elected to implement the
requirements of paragraph (g)(1) of this section, and a period of 6
consecutive months has passed without an excursion as defined in
paragraph (g)(2)(iv) of this section, the owner or operator is no longer
required to record the daily average value for that parameter for that
unit of equipment, for any operating day when the daily average value is
less than the maximum, or greater than the minimum established limit.
With approval by the Administrator, monitoring data generated prior to
the compliance date of this subpart shall be credited toward the period
of 6 consecutive months, if the parameter limit and the monitoring was
required and/or approved by the Administrator.
(i) If the owner or operator elects not to retain the daily average
values, the owner or operator shall notify the Administrator in the next
periodic report. The notification shall identify the parameter and unit
of equipment.
(ii) If, on any operating day after the owner or operator has ceased
recording daily averages as provided in paragraph (g)(2) of this
section, there is an excursion as defined in paragraph (g)(2)(iv) of
this section, the owner or operator shall immediately resume retaining
the daily average value for each day, and shall notify the Administrator
in the next periodic report. The owner or operator shall continue to
retain each daily average value until another period of 6 consecutive
months has passed without an excursion as defined in paragraph
(g)(2)(iv) of this section.
(iii) The owner or operator shall retain the records specified in
paragraphs (g)(1) (i), (ii), (iii), (iv), (v), and (vi) of this section.
For any calendar week, if compliance with paragraphs (g)(1) (i), (ii),
(iii), and (iv) of this section does not result in retention of a record
of at least one occurrence or measured parameter value, the owner or
operator shall record and retain at least one parameter value during a
period of operation other than a startup, shutdown, or malfunction.
(iv) For purposes of paragraph (g) of this section, an excursion
means that the daily average value of monitoring data for a parameter is
greater than the maximum, or less than the minimum established value,
except as provided in paragraphs (g)(2)(iv)(A) and (g)(2)(iv)(B) of this
section.
(A) The daily average value during any startup, shutdown, or
malfunction shall not be considered an excursion for purposes of this
paragraph (g)(2), if the owner or operator operates the source during
such periods in accordance with Sec. 63.102(a)(4).
(B) An excused excursion, as described in Sec. 63.152(c)(2)(ii) (B)
and (C), shall not be considered an excursion for purposes of this
paragraph (g)(2).

In liquid service means that a piece of equipment in organic
hazardous air pollutant service is not in gas/vapor service.
In organic hazardous air pollutant or in organic HAP service means
that a piece of equipment either contains or contacts a fluid (liquid or
gas) that is at least 5 percent by weight of total organic HAP's as
determined according to the provisions of Sec. 63.180(d) of this
subpart. The provisions of Sec. 63.180(d) of this subpart also specify
how to determine that a piece of equipment is not in organic HAP
service.

(e.g., composition, pressure, flow, etc.). Valves and connectors are the
predominant type of equipment used in instrumentation systems; however,
other types of equipment may also be included in these systems. Only
valves nominally 0.5 inches and smaller, and connectors nominally 0.75
inches and smaller in diameter are considered instrumentation systems
for the purposes of this subpart. Valves greater than nominally 0.5
inches and connectors greater than nominally 0.75 inches associated with
instrumentation systems are not considered part of instrumentation
systems and must be monitored individually.
Liquids dripping means any visible leakage from the seal including
dripping, spraying, misting, clouding, and ice formation. Indications of
liquid dripping include puddling or new stains that are indicative of an
existing evaporated drip.
Nonrepairable means that it is technically infeasible to repair a
piece of equipment from which a leak has been detected without a process
unit shutdown.
On-site or On site means, with respect to records required to be
maintained by this subpart, that the records are stored at a location
within a major source which encompasses the affected source. On-site
includes, but is not limited to, storage at the chemical manufacturing
process unit to which the records pertain, or storage in central files
elsewhere at the major source.
Open-ended valve or line means any valve, except pressure relief
valves, having one side of the valve seat in contact with process fluid
and one side open to atmosphere, either directly or through open piping.
Plant site means all contiguous or adjoining property that is under
common control, including properties that are separated only by a road
or other public right-of-way. Common control includes properties that
are owned, leased, or operated by the same entity, parent entity,
subsidiary, or any combination thereof.
Polymerizing monomer means a molecule or compound usually containing
carbon and of relatively low molecular weight and simple structure
(e.g., hydrogen cyanide, acrylonitrile, styrene), which is capable of
conversion to polymers, synthetic resins, or elastomers by combination
with itself due to heat generation caused by a pump mechanical seal
surface, contamination by a seal fluid (e.g., organic peroxides or
chemicals that will form organic peroxides), or a combination of both
with the resultant polymer buildup causing rapid mechanical seal
failure.
Pressure release means the emission of materials resulting from the
system pressure being greater than the set pressure of the pressure
relief device. This release can be one release or a series of releases
over a short time period due to a malfunction in the process.
Pressure relief device or valve means a safety device used to
prevent operating pressures from exceeding the maximum allowable working
pressure of the process equipment. A common pressure relief device is a
spring-loaded pressure relief valve. Devices that are actuated either by
a pressure of less than or equal to 2.5 psig or by a vacuum are not
pressure relief devices.
Process unit means a chemical manufacturing process unit as defined
in subpart F of this part, a process subject to the provisions of
subpart I of this part, or a process subject to another subpart in 40
CFR part 63 that references this subpart.
Process unit shutdown means a work practice or operational procedure
that stops production from a process unit or part of a process unit
during which it is technically feasible to clear process material from a
process unit or part of a process unit consistent with safety
[[Page 389]]
constraints and during which repairs can be effected. An unscheduled
work practice or operational procedure that stops production from a
process unit or part of a process unit for less than 24 hours is not a
process unit shutdown. An unscheduled work practice or operational
procedure that would stop production from a process unit or part of a
process unit for a shorter period of time than would be required to
clear the process unit or part of the process unit of materials and
start up the unit, and would result in greater emissions than delay of
repair of leaking components until the next scheduled process unit
shutdown, is not a process unit shutdown. The use of spare equipment and
technically feasible bypassing of equipment without stopping production
are not process unit shutdowns.
Recapture device means an individual unit of equipment capable of
and used for the purpose of recovering chemicals, but not normally for
use, reuse, or sale. Recapture devices include, but are not limited to,
absorbers, carbon absorbers, and condensers.
Recovery device means an individual unit of equipment capable of and
normally 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. Recovery devices include, but are not limited to,
absorbers, carbon absorbers, and condensers. For purposes of the
monitoring, recordkeeping, and reporting requirements of this subpart,
recapture devices are considered recovery devices.
Repaired means that equipment:
(1) Is adjusted, or otherwise altered, to eliminate a leak as
defined in the applicable sections of this subpart, and
(2) Unless otherwise specified in applicable provisions of this
subpart, is monitored as specified in Sec. 63.180 (b) and (c), as
appropriate, to verify that emissions from the equipment are below the
applicable leak definition.
Routed to a process or route to a process means the emissions are
conveyed by hard-piping or a closed vent system to any enclosed portion
of a process unit where the emissions are predominately recycled and/or
consumed in the same manner as a material that fulfills the same
function in the process; and/or transformed by chemical reaction into
materials that are not organic hazardous air pollutants; and/or
incorporated into a product; and/or recovered.
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 non-routine grab
samples is not considered a sampling connection system.
Screwed connector means a threaded pipe fitting where the threads
are cut on the pipe wall and the fitting requires only two pieces to
make the connection (i.e., the pipe and the fitting).
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.
Start-up means the setting in operation of a piece of equipment or a
control device that is subject to this subpart.
Surge control vessel means feed drums, recycle drums, and
intermediate vessels. Surge control vessels are used within a process
unit (as defined in the specific subpart that references this subpart)
when in-process storage, mixing, or management of flow rates or volumes
is needed to assist in production of a product.

Sec. 63.162 Standards: General.
(a) Compliance with this subpart will be determined by review of the
records required by Sec. 63.181 of this subpart and the reports
required by Sec. 63.182 of this subpart, review of performance test
results, and by inspections.
(b)(1) An owner or operator may request a determination of
alternative means of emission limitation to the requirements of
Sec. Sec. 63.163 through 63.170,
[[Page 390]]
and Sec. Sec. 63.172 through 63.174 of this subpart as provided in
Sec. 63.177.
(2) If the Administrator makes a determination that a means of
emission limitation is a permissible alternative to the requirements of
Sec. Sec. 63.163 through 63.170, and Sec. Sec. 63.172 through 63.174
of this subpart, the owner or operator shall comply with the
alternative.
(c) Each piece of equipment in a process unit to which this subpart
applies shall be identified such that it can be distinguished readily
from equipment that is not subject to this subpart. 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 unit boundaries by some form of
weatherproof identification.
(d) Equipment that is in vacuum service is excluded from the
requirements of this subpart.
(e) Equipment that is in organic HAP service less than 300 hours per
calendar year is excluded from the requirements of Sec. Sec. 63.163
through 63.174 of this subpart and Sec. 63.178 of this subpart if it is
identified as required in Sec. 63.181(j) of this subpart.
(f) When each leak is detected as specified in Sec. Sec. 63.163 and
63.164; Sec. Sec. 63.168 and 63.169; and Sec. Sec. 63.172 through
63.174 of this subpart, the following requirements apply:
(1) Clearly identify the leaking equipment.
(2) The identification on a valve may be removed after it has been
monitored as specified in Sec. Sec. 63.168(f)(3), and
63.175(e)(7)(i)(D) of this subpart, and no leak has been detected during
the follow-up monitoring. If the owner or operator elects to comply
using the provisions of Sec. 63.174(c)(1)(i) of this subpart, the
identification on a connector may be removed after it is monitored as
specified in Sec. 63.174(c)(1)(i) and no leak is detected during that
monitoring.
(3) The identification which has been placed on equipment determined
to have a leak, except for a valve or for a connector that is subject to
the provisions of Sec. 63.174(c)(1)(i), may be removed after it is
repaired.
(g) Except as provided in paragraph (g)(1) of this section, all
terms in this subpart that define a period of time for completion of
required tasks (e.g., weekly, monthly, quarterly, annual), refer to the
standard calendar periods unless specified otherwise in the section or
subsection that imposes the requirement.
(1) If the initial compliance date does not coincide with the
beginning of the standard calendar period, an owner or operator may
elect to utilize a period beginning on the compliance date, or may elect
to comply in accordance with the provisions of paragraphs (g)(2) or
(g)(3) of this section.
(2) Time periods specified in this subpart for completion of
required tasks may be changed by mutual agreement between the owner or
operator and the Administrator, as specified in subpart A of this part.
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.
(3) Except as provided in paragraph (g)(1) or (g)(2) of this
section, where the period specified for compliance is a standard
calendar period, if the initial compliance date does not coincide with
the beginning of the calendar period, compliance shall be required
according to the schedule specified in paragraphs (g)(3)(i) or
(g)(3)(ii) of this section, as appropriate.
(i) Compliance shall be required before the end of the standard
calendar period within which the compliance deadline occurs, if there
remain at least 3 days for tasks that must be performed weekly, at least
2 weeks for tasks that must be performed monthly, at least 1 month for
tasks that must be performed each quarter, or at least 3 months for
tasks that must be performed annually; or
(ii) In all other cases, compliance shall be required before the end
of the first full standard calendar period after the period within which
the initial compliance deadline occurs.
(4) In all instances where a provision of this subpart requires
completion of a task during each of multiple successive periods, an
owner or operator may perform the required task at any time during each
period, provided the task is conducted at a reasonable interval
[[Page 391]]
after completion of the task during the previous period.
(h) 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 subpart to fail to take action to
repair the leaks within the specified time. If action is taken to repair
the leaks within the specified time, failure of that action to
successfully repair the leak is not a violation of this subpart.
However, if the repairs are unsuccessful, a leak is detected and the
owner or operator shall take further action as required by applicable
provisions of this subpart.

specified in Sec. 63.180(b) of this subpart to determine if there is a
leak of organic HAP in the barrier fluid.
(ii) If an instrument reading of 1,000 parts per million or greater
is measured, a leak is detected.
(5) Each sensor as described in paragraph (e)(3) of this section is
observed daily or is equipped with an alarm unless the pump is located
within the boundary of an unmanned plant site.
(6)(i) The owner or operator determines, based on design
considerations and operating experience, criteria applicable to the
presence and frequency of drips and to the sensor that indicates failure

Sec. 63.168 Standards: Valves in gas/vapor service
and in light liquid service.
(a) The provisions of this section apply to valves that are either
in gas service or in light liquid service.
(1) The provisions are to be implemented on the dates set forth in
the specific subpart in 40 CFR part 63 that references this subpart as
specified in paragraph (a)(1)(i), (a)(1)(ii), or (a)(1)(iii) of this
section.
(i) For each group of existing process units at existing sources
subject to the provisions of subpart F or I of this part, the phases of
the standard are:
(A) Phase I, beginning on the compliance date;
(B) Phase II, beginning no later than 1 year after the compliance
date; and
(C) Phase III, beginning no later than 2\1/2\ years after the
compliance date.

this part, the applicable phases of the standard are:
(A) After initial start-up, comply with the Phase II requirements;
and
(B) Beginning no later than 1 year after initial start-up, comply
with the Phase III requirements.
(iii) Sources subject to other subparts in 40 CFR part 63 that
reference this subpart shall comply on the dates specified in the
applicable subpart.
(2) The owner or operator of a source subject to this subpart may
elect to meet the requirements of a later phase during the time period
specified for an earlier phase.
(3) The use of monitoring data generated before April 22, 1994 to
qualify for less frequent monitoring is governed by the provisions of
Sec. 63.180(b)(6) of this subpart.
(b) The owner or operator of a source subject to this subpart shall
monitor all valves, except as provided in Sec. 63.162(b) of this
subpart and paragraphs (h) and (i) of this section, at the intervals
specified in paragraphs (c) and (d) of this section and shall comply
with all other provisions of this section, except as provided in Sec.
63.171, Sec. 63.177, Sec. 63.178, and Sec. 63.179 of this subpart.
(1) The valves shall be monitored to detect leaks by the method
specified in Sec. 63.180(b) of this subpart.
[[Page 396]]
(2) The instrument reading that defines a leak in each phase of the
standard is:
(i) For Phase I, an instrument reading of 10,000 parts per million
or greater.
(ii) For Phase II, an instrument reading of 500 parts per million or
greater.
(iii) For Phase III, an instrument reading of 500 parts per million
or greater.
(c) In Phases I and II, each valve shall be monitored quarterly.
(d) In Phase III, the owner or operator shall monitor valves for
leaks at the intervals specified below:
(1) At process units with 2 percent or greater leaking valves,
calculated according to paragraph (e) of this section, the owner or
operator shall either:
(i) Monitor each valve once per month; or
(ii) Within the first year after the onset of Phase III, implement a
quality improvement program for valves that complies with the
requirements of Sec. 63.175 (d) or (e) of this subpart and monitor
quarterly.
(2) At process units with less than 2 percent leaking valves, the
owner or operator shall monitor each valve once each quarter, except as
provided in paragraphs (d)(3) and (d)(4) of this section.
(3) At process units with less than 1 percent leaking valves, the
owner or operator may elect to monitor each valve once every 2 quarters.
(4) At process units with less than 0.5 percent leaking valves, the
owner or operator may elect to monitor each valve once every 4 quarters.
(e)(1) Percent leaking valves at a process unit shall be determined
by the following equation:
%VL = (VL/(VT + VC)) x 100
where:
%VL = Percent leaking valves as determined through periodic
monitoring required in paragraphs (b) through (d) of this
section.
VL = Number of valves found leaking excluding nonrepairables
as provided in paragraph (e)(3)(i) of this section.
VT = Total valves monitored, in a monitoring period excluding
valves monitored as required by (f)(3) of this section.
VC = Optional credit for removed valves = 0.67 x net number
(i.e., total removed-total added) of valves in organic HAP
service removed from process unit after the date set forth in
Sec. 63.100(k) of subpart F for existing process units, and
after the date of initial start-up for new sources. If credits
are not taken, then VC = 0.
(2) For use in determining monitoring frequency, as specified in
paragraph (d) of this section, the percent leaking valves shall be
calculated as a rolling average of two consecutive monitoring periods
for monthly, quarterly, or semiannual monitoring programs; and as an
average of any three out of four consecutive monitoring periods for
annual monitoring programs.
(3)(i) 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)(3)(ii) 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 unit may be excluded from calculation of percent
leaking valves for subsequent monitoring periods.
(ii) If the number of nonrepairable valves exceeds 1 percent of the
total number of valves in organic HAP service at a process unit, 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.
(f)(1) 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 Sec. 63.171 of this subpart.
(2) A first attempt at repair shall be made no later than 5 calendar
days after each leak is detected.
(3) When a leak has been repaired, the valve shall be monitored at
least once within the first 3 months after its repair.
(i) The monitoring shall be conducted as specified in Sec. 63.180
(b) and (c), as appropriate, to determine whether the valve has resumed
leaking.
[[Page 397]]
(ii) Periodic monitoring required by paragraphs (b) through (d) of
this section may be used to satisfy the requirements of this paragraph
(f)(3), if the timing of the monitoring period coincides with the time
specified in this paragraph (f)(3). Alternatively, other monitoring may
be performed to satisfy the requirements of this paragraph (f)(3),
regardless of whether the timing of the monitoring period for periodic
monitoring coincides with the time specified in this paragraph (f)(3).
(iii) If a leak is detected by monitoring that is conducted pursuant
to paragraph (f)(3) of this section, the owner or operator shall follow
the provisions of paragraphs (f)(3)(iii)(A) and (f)(3)(iii)(B) of this
section, to determine whether that valve must be counted as a leaking
valve for purposes of Sec. 63.168(e) of this subpart.
(A) If the owner or operator elected to use periodic monitoring
required by paragraphs (b) through (d) of this section to satisfy the
requirements of paragraph (f)(3) of this section, then the valve shall
be counted as a leaking valve.
(B) If the owner or operator elected to use other monitoring, prior
to the periodic monitoring required by paragraphs (b) through (d) of
this section, to satisfy the requirements of paragraph (f)(3) of this
section, then the valve shall be counted as a leaking valve unless it is
repaired and shown by periodic monitoring not to be leaking.
(g) First attempts at repair include, but are not limited to, the
following practices where practicable:
(1) Tightening of bonnet bolts,
(2) Replacement of bonnet bolts,
(3) Tightening of packing gland nuts, and
(4) Injection of lubricant into lubricated packing.
(h) Any valve that is designated, as described in Sec.
63.181(b)(7)(i) of this subpart, as an unsafe-to-monitor valve is exempt
from the requirements of paragraphs (b) through (f) of this section if:
(1) The owner or operator of the valve determines that the valve is
unsafe to monitor because monitoring personnel would be exposed to an
immediate danger as a consequence of complying with paragraphs (b)
through (d) of this section; and
(2) The owner or operator of the valve has a written plan that
requires monitoring of the valve as frequently as practicable during
safe-to-monitor times, but not more frequently than the periodic
monitoring schedule otherwise applicable.
(i) Any valve that is designated, as described in Sec.
63.181(b)(7)(ii) of this subpart, as a difficult-to-monitor valve is
exempt from the requirements of paragraphs (b) through (d) of this
section if:
(1) The owner or operator of the valve determines that the valve
cannot be monitored without elevating the monitoring personnel more than
2 meters above a support surface or it is not accessible at anytime in a
safe manner;
(2) The process unit within which the valve is located is an
existing source or the owner or operator designates less than 3 percent
of the total number of valves in a new source as difficult-to-monitor;
and
(3) The owner or operator of the valve follows a written plan that
requires monitoring of the valve at least once per calendar year.
(j) Any equipment located at a plant site with fewer than 250 valves
in organic HAP service is exempt from the requirements for monthly
monitoring and a quality improvement program specified in paragraph
(d)(1) of this section. Instead, the owner or operator shall monitor
each valve in organic HAP service for leaks once each quarter, or comply
with paragraph (d)(3) or (d)(4) of this section except as provided in
paragraphs (h) and (i) of this section.

connectors in the process unit was 0.5 percent or greater during the
last required annual or biennial monitoring period.
(ii) Once every 2 years, if the percent leaking connectors was less
than 0.5 percent during the last required monitoring period. An owner or
operator may comply with this paragraph by monitoring at least 40
percent of the connectors in the first year and the remainder of the
connectors in the second year. The percent leaking connectors will be
calculated for the total of all monitoring performed during the 2-year
period.
(iii) If the owner or operator of a process unit in a biennial leak
detection and repair program calculates less than 0.5 percent leaking
connectors from the 2-year monitoring period, the owner or operator may
monitor the connectors one time every 4 years. An owner or operator may
comply with the requirements of this paragraph by monitoring at least 20
percent of the connectors each year until all connectors have been
monitored within 4 years.
(iv) If a process unit complying with the requirements of paragraph
(b) of this section using a 4-year monitoring interval program has
greater than or equal to 0.5 percent but less than 1 percent leaking
connectors, the owner or operator shall increase the monitoring
frequency to one time every 2 years. An owner or operator may comply
with the requirements of this paragraph by monitoring at least 40
percent of the connectors in the first year and the remainder of the
connectors in the second year. The owner or operator may again elect to
use the provisions of paragraph (b)(3)(iii) of this section when the
percent leaking connectors decreases to less than 0.5 percent.
(v) If a process unit complying with requirements of paragraph
(b)(3)(iii) of
[[Page 403]]
this section using a 4-year monitoring interval program has 1 percent or
greater leaking connectors, the owner or operator shall increase the
monitoring frequency to one time per year. The owner or operator may
again elect to use the provisions of paragraph (b)(3)(iii) of this
section when the percent leaking connectors decreases to less than 0.5
percent.
(4) The use of monitoring data generated before April 22, 1994 to
qualify for less frequent monitoring is governed by the provisions of
Sec. 63.180(b)(6).
(c)(1)(i) Except as provided in paragraph (c)(1)(ii) of this
section, each connector that has been opened or has otherwise had the
seal broken shall be monitored for leaks when it is reconnected or
within the first 3 months after being returned to organic hazardous air
pollutants service. If the monitoring detects a leak, it shall be
repaired according to the provisions of paragraph (d) of this section,
unless it is determined to be nonrepairable, in which case it is counted
as a nonrepairable connector for the purposes of paragraph (i)(2) of
this section.
(ii) As an alternative to the requirements in paragraph (c)(1)(i) of
this section, an owner or operator may choose not to monitor connectors
that have been opened or otherwise had the seal broken. In this case,
the owner or operator may not count nonrepairable connectors for the
purposes of paragraph (i)(2) of this section. The owner or operator
shall calculate the percent leaking connectors for the monitoring
periods described in paragraph (b) of this section, by setting the
nonrepairable component, CAN, in the equation in paragraph
(i)(2) of this section to zero for all monitoring periods.
(iii) An owner or operator may switch alternatives described in
paragraphs (c)(1) (i) and (ii) of this section at the end of the current
monitoring period he is in, provided that it is reported as required in
Sec. 63.182 of this subpart and begin the new alternative in annual
monitoring. The initial monitoring in the new alternative shall be
completed no later than 12 months after reporting the switch.
(2) As an alternative to the requirements of paragraph (b)(3) of
this section, each screwed connector 2 inches or less in nominal inside
diameter installed in a process unit before the dates specified in
paragraph (c)(2)(iii) or (c)(2)(iv) of this section may:
(i) Comply with the requirements of Sec. 63.169 of this subpart,
and
(ii) Be monitored for leaks within the first 3 months after being
returned to organic hazardous air pollutants service after having been
opened or otherwise had the seal broken. If that monitoring detects a
leak, it shall be repaired according to the provisions of paragraph (d)
of this section.
(iii) For sources subject to subparts F and I of this part, the
provisions of paragraph (c)(2) of this section apply to screwed
connectors installed before December 31, 1992.
(iv) For sources not identified in paragraph (c)(2)(iii) of this
section, the provisions of paragraph (c)(2) of this section apply to
screwed connectors installed before the date of proposal of the
applicable subpart of this part that references this subpart.
(d) 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 (g) of this section and in
Sec. 63.171 of this subpart. A first attempt at repair shall be made no
later than 5 calendar days after the leak is detected.
(e) [Reserved]
(f) Any connector that is designated, as described in Sec.
63.181(b)(7)(i) of this subpart, as an unsafe-to-monitor connector is
exempt from the requirements of paragraph (a) of this section if:
(1) The owner or operator determines that the connector is unsafe to
monitor because personnel would be exposed to an immediate danger as a
result of complying with paragraphs (a) through (e) of this section; and
(2) The owner or operator has a written plan that requires
monitoring of the connector as frequently as practicable during safe to
monitor periods, but not more frequently than the periodic schedule
otherwise applicable.
(g) Any connector that is designated, as described in Sec.
63.181(b)(7)(iii) of this
[[Page 404]]
subpart, as an unsafe-to-repair connector is exempt from the
requirements of paragraphs (a), (d), and (e) of this section if:
(1) The owner or operator determines that repair personnel would be
exposed to an immediate danger as a consequence of complying with
paragraph (d) of this section; and
(2) The connector will be repaired before the end of the next
scheduled process unit shutdown.
(h)(1) Any connector that is inaccessible or is ceramic or ceramic-
lined (e.g., porcelain, glass, or glass-lined), is exempt from the
monitoring requirements of paragraphs (a) and (c) of this section and
from the recordkeeping and reporting requirements of Sec. 63.181 and
Sec. 63.182 of this subpart. An inaccessible connector is one that is:
(i) Buried;
(ii) Insulated in a manner that prevents access to the connector by
a monitor probe;
(iii) Obstructed by equipment or piping that prevents access to the
connector by a monitor probe;
(iv) Unable to be reached from a wheeled scissor-lift or hydraulic-
type scaffold which would allow access to connectors up to 7.6 meters
(25 feet) above the ground;
(v) Inaccessible because it would require elevating the monitoring
personnel more than 2 meters above a permanent support surface or would
require the erection of scaffold; or
(vi) Not able to be accessed at any time in a safe manner to perform
monitoring. Unsafe access includes, but is not limited to, the use of a
wheeled scissor-lift on unstable or uneven terrain, the use of a
motorized man-lift basket in areas where an ignition potential exists,
or access would require near proximity to hazards such as electrical
lines, or would risk damage to equipment.
(2) If any inaccessible or ceramic or ceramic-lined connector is
observed by visual, audible, olfactory, or other means to be leaking,
the leak shall be repaired as soon as practicable, but no later than 15
calendar days after the leak is detected, except as provided in Sec.
63.171 of this subpart and paragraph (g) of this section.
(3) A first attempt at repair shall be made no later than 5 calendar
days after the leak is detected.
(i) For use in determining the monitoring frequency, as specified in
paragraph (b) of this section, the percent leaking connectors shall be
calculated as specified in paragraphs (i)(1) and (i)(2) of this section.
(1) For the first monitoring period, use the following equation:
% CL = CL/(Ct + CC) x 100
where:
% CL = Percent leaking connectors as determined through
periodic monitoring required in paragraphs (a) and (b) of this
section.
CL = Number of connectors measured at 500 parts per million
or greater, by the method specified in Sec. 63.180(b) of this
subpart.
Ct = Total number of monitored connectors in the process
unit.
CC = Optional credit for removed connectors = 0.67 x net
(i.e., total removed--total added) number of connectors in
organic hazardous air pollutants service removed from the
process unit after the compliance date set forth in the
applicable subpart for existing process units, and after the
date of initial start-up for new process units. If credits are
not taken, then CC = 0.
(2) For subsequent monitoring periods, use the following equation:
% CL = [(CL- CAN)/(Ct +
CC)] x 100
where:
% CL = Percent leaking connectors as determined through
periodic monitoring required in paragraphs (a) and (b) of this
section.
CL = Number of connectors, including nonrepairables, measured
at 500 parts per million or greater, by the method specified
in Sec. 63.180(b) of this subpart.
CAN = Number of allowable nonrepairable connectors, as
determined by monitoring required in paragraphs (b)(3) and (c)
of this section, not to exceed 2 percent of the total
connector population, Ct.
Ct = Total number of monitored connectors, including
nonrepairables, in the process unit.
CC = Optional credit for removed connectors = 0.67 x net
number (i.e., total removed--total added) of connectors in
organic hazardous air pollutants service removed from the
process unit after the compliance date set forth in the
applicable subpart for existing process units, and after
[[Page 405]]
the date of initial start-up for new process units. If credits
are not taken, then CC = 0.
(j) Optional credit for removed connectors. If an owner or operator
eliminates a connector subject to monitoring under paragraph (b) of this
section, the owner or operator may receive credit for elimination of the
connector, as described in paragraph (i) of this section, provided the
requirements in paragraphs (j)(1) through (j)(4) are met.
(1) The connector was welded after the date of proposal of the
specific subpart that references this subpart.
(2) The integrity of the weld is demonstrated by monitoring it
according to the procedures in Sec. 63.180(b) of this subpart or by
testing using X-ray, acoustic monitoring, hydrotesting, or other
applicable method.
(3) Welds created after the date of proposal but before the date of
promulgation of a specific subpart that references this subpart are
monitored or tested by 3 months after the compliance date specified in
the applicable subpart.
(4) Welds created after promulgation of the subpart that references
this subpart are monitored or tested within 3 months after being welded.
(5) If an inadequate weld is found or the connector is not welded
completely around the circumference, the connector is not considered a
welded connector and is therefore not exempt from the provisions of this
subpart.

Sec. 63.175 Quality improvement program for valves.
(a) In Phase III, an owner or operator may elect to comply with one
of the alternative quality improvement programs specified in paragraphs
(d) and (e) of this section. The decision to use one of these
alternative provisions to comply with the requirements of Sec.
63.168(d)(1)(ii) of this subpart must be made during the first year of
Phase III for existing process units and for new process units.
(b) An owner or operator of a process unit subject to the
requirements of paragraph (d) or (e) of this section shall comply with
those requirements until the process unit has fewer than 2 percent
leaking valves, calculated as a rolling average of 2 consecutive
quarters, as specified in Sec. 63.168(e) of this subpart.
(c) After the process unit has fewer than 2 percent leaking valves,
the owner or operator may elect to comply with the requirements in Sec.
63.168 of this subpart, to continue to comply with the requirements in
paragraph (e) (or (d), if appropriate) of this section, or comply with
both the requirements in Sec. 63.168 and Sec. 63.175.
(1) If the owner or operator elects to continue the quality
improvement program, the owner or operator is exempt from the
requirements for performance trials as specified in paragraph (e)(6) of
this section, or further progress as specified in paragraph (d)(4) of
this section, as long as the process unit has fewer than 2 percent
leaking valves calculated according to Sec. 63.168(e).
(2) If the owner or operator elects to comply with both paragraph
(e) of this section and Sec. 63.168 of this subpart, he may also take
advantage of the lower monitoring frequencies associated with lower leak
rates in Sec. 63.168 (d)(2), (d)(3), and (d)(4) of this subpart.
(3) If the owner or operator elects not to continue the quality
improvement program, the program is no longer an option if the process
unit again exceeds 2 percent leaking valves, and in such case, monthly
monitoring will be required.
(d) The following requirements shall be met if an owner or operator
elects to use a quality improvement program to demonstrate further
progress:
(1) The owner or operator shall continue to comply with the
requirements in Sec. 63.168 of this subpart except each valve shall be
monitored quarterly.
(2) The owner or operator shall collect the following data, and
maintain records as required in Sec. 63.181(h)(1) of this subpart, for
each valve in each process unit subject to the quality improvement
program:
(i) The maximum instrument reading observed in each monitoring
observation before repair, the response factor for the stream if
appropriate, the instrument model number, and date of the observation.
[[Page 406]]
(ii) Whether the valve is in gas or light liquid service.
(iii) If a leak is detected, the repair methods used and the
instrument readings after repair.
(3) The owner or operator shall continue to collect data on the
valves as long as the process unit remains in the quality improvement
program.
(4) The owner or operator must demonstrate progress in reducing the
percent leaking valves each quarter the process unit is subject to the
requirements of paragraph (d) of this section, except as provided in
paragraphs (d)(4)(ii) and (d)(4)(iii) of this section.
(i) Demonstration of progress shall mean that for each quarter there
is at least a 10-percent reduction in the percent leaking valves from
the percent leaking valves determined for the preceding monitoring
period. The percent leaking valves shall be calculated as a rolling
average of two consecutive quarters of monitoring data. The percent
reduction shall be calculated using the rolling average percent leaking
valves, according to the following:
%LVR = (%LVAVG1 - %LVAVG2 /
%LVAVG1 x 100
where:
%LVR = Percent leaking valve reduction.
%LVAVG1 = (%VLi + %VLi = 1)/2.
%LVAVG2 = (%VLi = 1 + %VLi = 2)/2.
where:
%VLi, %VLi = 1, %VLi = 2 are percent
leaking valves calculated for subsequent monitoring periods,
i, i + 1, i + 2.
(ii) An owner or operator who fails for two consecutive rolling
averages to demonstrate at least a 10-percent reduction per quarter in
percent leaking valves, and whose overall average percent reduction
based on two or more rolling averages is less than 10 percent per
quarter, shall either comply with the requirements in Sec.
63.168(d)(1)(i) of this subpart using monthly monitoring or shall comply
using a quality improvement program for technology review as specified
in paragraph (e) of this section. If the owner or operator elects to
comply with the requirements of paragraph (e) of this section, the
schedule for performance trials and valve replacements remains as
specified in paragraph (e) of this section.
(iii) As an alternative to the provisions in paragraph (d)(4)(i), an
owner or operator may use the procedure specified in paragraphs
(d)(4)(iii)(A) and (d)(4)(iii)(B) of this section to demonstrate
progress in reducing the percent leaking valves.
(A) The percent reduction that must be achieved each quarter shall
be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR22AP94.293
%RR = percent reduction required each quarter, as calculated according
to Sec. 63.168(e)
%VL = percent leaking valves, calculated according to Sec.
63.168(e), at the time elected to use provisions of Sec.
63.168(d)(1)(ii)
(B) The owner or operator shall achieve less than 2 percent leaking
valves no later than 2 years after electing to use the demonstration of
progress provisions in Sec. 63.175(d) of this subpart.
(e) The following requirements shall be met if an owner or operator
elects to use a quality improvement program of technology review and
improvement:
(1) The owner or operator shall comply with the requirements in
Sec. 63.168 of this subpart except the requirement for monthly
monitoring in Sec. 63.168(d)(1)(i) of this subpart does not apply.

and maintain records as required in Sec. 63.181(h)(2), for each valve
in each process unit subject to the quality improvement program. The
data may be collected and the records may be maintained on a process
unit or group of process units basis. The data shall include the
following:
(i) Valve type (e.g., ball, gate, check); valve manufacturer; valve
design (e.g., external stem or actuating mechanism, flanged body);
materials of construction; packing material; and year installed.
(ii) Service characteristics of the stream such as operating
pressure, temperature, line diameter, and corrosivity.
(iii) Whether the valve is in gas or light liquid service.
(iv) The maximum instrument readings observed in each monitoring
observation before repair, response factor
[[Page 407]]
for the stream if adjusted, instrument model number, and date of the
observation.
(v) If a leak is detected, the repair methods used and the
instrument readings after repair.
(vi) If the data will be analyzed as part of a larger analysis
program involving data from other plants or other types of process
units, a description of any maintenance or quality assurance programs
used in the process unit that are intended to improve emission
performance.
(3) The owner or operator shall continue to collect data on the
valves as long as the process unit remains in the quality improvement
program.
(4) The owner or operator shall inspect all valves removed from the
process unit due to leaks. The inspection shall determine which parts of
the valve have failed and shall include recommendations, as appropriate,
for design changes or changes in specifications to reduce leak
potential.
(5)(i) The owner or operator shall analyze the data collected to
comply with the requirements of paragraph (e)(2) of this section to
determine the services, operating or maintenance practices, and valve
designs or technologies that have poorer than average emission
performance and those that have better than average emission
performance. The analysis shall determine if specific trouble areas can
be identified on the basis of service, operating conditions or
maintenance practices, equipment design, or other process specific
factors.
(ii) The analysis shall also be used to identify any superior
performing valve technologies that are applicable to the service(s),
operating conditions, or valve designs associated with poorer than
average emission performance. A superior performing valve technology is
one for which a group of such valves has a leak frequency of less than 2
percent for specific applications in such a process unit. A candidate
superior performing valve technology is one demonstrated or reported in
the available literature or through a group study as having low emission
performance and as being capable of achieving less than 2 percent
leaking valves in the process unit.
(iii) The analysis shall include consideration of:
(A) The data obtained from the inspections of valves removed from
the process unit due to leaks,
(B) Information from the available literature and from the
experience of other plant sites that will identify valve designs or
technologies and operating conditions associated with low emission
performance for specific services, and
(C) Information on limitations on the service conditions for the
valve design and operating conditions as well as information on
maintenance procedures to ensure continued low emission performance.
(iv) The data analysis may be conducted through an inter- or intra-
company program (or through some combination of the two approaches) and
may be for a single process unit, a company, or a group of process
units.
(v) The first analysis of the data shall be completed no later than
18 months after the start of Phase III. The first analysis shall be
performed using a minimum of two quarters of data. An analysis of the
data shall be done each year the process unit is in the quality
improvement program.
(6) A trial evaluation program shall be conducted at each plant site
for which the data analysis does not identify superior performing valve
designs or technologies that can be applied to the operating conditions
and services identified as having poorer than average performance,
except as provided in paragraph (e)(6)(v) of this section. The trial
program shall be used to evaluate the feasibility of using in the
process unit the valve designs or technologies that have been identified
by others as having low emission performance.
(i) The trial program shall include on-line trials of valves or
operating and maintenance practices that have been identified in the
available literature or in analysis by others as having the ability to
perform with leak rates below 2 percent in similar services, as having
low probability of failure, or as having no external actuating mechanism
in contact with the process fluid. If any of the candidate superior
performing valve technologies is not included in the performance trials,
the
[[Page 408]]
reasons for rejecting specific technologies from consideration shall be
documented as required in Sec. 63.181(h)(5)(ii) of this subpart.
(ii) The number of valves in the trial evaluation program shall be
the lesser of 1 percent or 20 valves for programs involving single
process units and the lesser of 1 percent or 50 valves for programs
involving groups of process units.
(iii) The trial evaluation program shall specify and include
documentation of:
(A) The candidate superior performing valve designs or technologies
to be evaluated, the stages for evaluating the identified candidate
valve designs or technologies, including the estimated time period
necessary to test the applicability;
(B) The frequency of monitoring or inspection of the equipment;
(C) The range of operating conditions over which the component will
be evaluated; and
(D) Conclusions regarding the emission performance and the
appropriate operating conditions and services for the trial valves.
(iv) The performance trials shall initially be conducted for, at
least, a 6-month period beginning not later than 18 months after the
start of Phase III. Not later than 24 months after the start of Phase
III, the owner or operator shall have identified valve designs or
technologies that, combined with appropriate process, operating, and
maintenance practices, operate with low emission performance for
specific applications in the process unit. The owner or operator shall
continue to conduct performance trials as long as no superior performing
design or technology has been identified, except as provided in
paragraph (e)(6)(vi) of this section. The compilation of candidate and
demonstrated superior emission performance valve designs or technologies
shall be amended in the future, as appropriate, as additional
information and experience is obtained.
(v) Any plant site with fewer than 400 valves and owned by a
corporation with fewer than 100 total employees shall be exempt from
trial evaluations of valves. Plant sites exempt from the trial
evaluations of valves shall begin the program at the start of the fourth
year of Phase III.
(vi) An owner or operator who has conducted performance trials on
all candidate superior emission performance technologies suitable for
the required applications in the process unit may stop conducting
performance trials provided that a superior performing design or
technology has been demonstrated or there are no technically feasible
candidate superior technologies remaining. The owner or operator shall
prepare an engineering evaluation documenting the physical, chemical, or
engineering basis for the judgment that the superior emission
performance technology is technically infeasible or demonstrating that
it would not reduce emissions.
(7) Each owner or operator who elects to use a quality improvement
program for technology review and improvement shall prepare and
implement a valve quality assurance program that details purchasing
specifications and maintenance procedures for all valves in the process
unit. The quality assurance program may establish any number of
categories, or classes, of valves as needed to distinguish among
operating conditions and services associated with poorer than average
emission performance as well as those associated with better than
average emission performance. The quality assurance program shall be
developed considering the findings of the data analysis required under
paragraph (e)(5) of this section, if applicable, the findings of the
trial evaluation required in paragraph (e)(6) of this section, and the
operating conditions in the process unit. The quality assurance program
shall be reviewed and, as appropriate, updated each year as long as the
process unit has 2 percent or more leaking valves.
(i) The quality assurance program shall:
(A) Establish minimum design standards for each category of valves.
The design standards shall specify known critical parameters such as
tolerance, manufacturer, materials of construction, previous usage, or
other applicable identified critical parameters;
(B) Require that all equipment orders specify the design standard
(or minimum tolerances) for the valve;
[[Page 409]]
(C) Include a written procedure for bench testing of valves that
specifies performance criteria for acceptance of valves and specifies
criteria for the precision and accuracy of the test apparatus. All
valves repaired off-line after preparation of the quality assurance plan
shall be bench-tested for leaks. This testing may be conducted by the
owner or operator of the process unit, by the vendor, or by a designated
representative. The owner or operator shall install only those valves
that have been documented through bench-testing to be nonleaking.
(D) Require that all valves repaired on-line be monitored using the
method specified in Sec. 63.180(b) of this subpart for leaks for 2
successive months, after repair.
(E) Provide for an audit procedure for quality control of purchased
equipment to ensure conformance with purchase specifications. The audit
program may be conducted by the owner or operator of the process unit or
by a designated representative.
(F) Detail off-line valve maintenance and repair procedures. These
procedures shall include provisions to ensure that rebuilt or
refurbished valves will meet the design specifications for the valve
type and will operate such that emissions are minimized.
(ii) The quality assurance program shall be established no later
than the start of the third year of Phase III for plant sites with 400
or more valves or owned by a corporation with 100 or more employees; and
no later than the start of the fourth year of Phase III for plant sites
with less than 400 valves and owned by a corporation with less than 100
employees.
(8) Beginning at the start of the third year of Phase III for plant
sites with 400 or more valves or owned by a corporation with 100 or more
employees and at the start of the fourth year of Phase III for plant
sites with less than 400 valves and owned by a corporation with less
than 100 employees, each valve that is replaced for any reason shall be
replaced with a new or modified valve that complies with the quality
assurance standards for the valve category and that is identified as
superior emission performance technology. Superior emission performance
technology means valves or valve technologies identified with emission
performance that, combined with appropriate process, operating, and
maintenance practices, will result in less than 2 percent leaking valves
for specific applications in a large population, except as provided in
paragraph (e)(8)(ii) of this section.
(i) The valves shall be maintained as specified in the quality
assurance program.
(ii) If a superior emission performance technology cannot be
identified, then valve replacement shall be with one of (if several) the
lowest emission performance technologies that has been identified for
the specific application.

unit due to leaks. The inspection shall determine the probable cause of
the pump seal failure or of the pump leak and shall include
recommendations, as appropriate, for design changes or changes in
specifications to reduce leak potential.
(5)(i) The owner or operator shall analyze the data collected to
comply with the requirements of paragraph (d)(2) of this section to
determine the services, operating or maintenance practices, and pump or
pump seal designs or technologies that have poorer than average emission
performance and those that have better than average emission
performance. The analysis shall determine if specific trouble areas can
be identified on the basis of service, operating conditions or
maintenance practices, equipment design, or other process specific
factors.
(ii) The analysis shall also be used to determine if there are
superior performing pump or pump seal technologies that are applicable
to the service(s), operating conditions, or pump or pump seal designs
associated with poorer than average emission performance. A superior
performing pump or pump seal technology is one with a leak frequency of
less than 10 percent for specific applications in the process unit or
plant site. A candidate superior performing pump or pump seal technology
is one demonstrated or reported in the available literature or through a
group study as having low emission performance and as being capable of
achieving less than 10 percent leaking pumps in the process unit (or
plant site).
(iii) The analysis shall include consideration of:
(A) The data obtained from the inspections of pumps and pump seals
removed from the process unit due to leaks;
(B) Information from the available literature and from the
experience of other plant sites that will identify pump designs or
technologies and operating conditions associated with low emission
performance for specific services; and
(C) Information on limitations on the service conditions for the
pump seal technology operating conditions as well as information on
maintenance procedures to ensure continued low emission performance.
[[Page 411]]
(iv) The data analysis may be conducted through an inter- or intra-
company program (or through some combination of the two approaches) and
may be for a single process unit, a plant site, a company, or a group of
process units.
(v) The first analysis of the data shall be completed no later than
18 months after the start of the quality improvement program. The first
analysis shall be performed using a minimum of 6 months of data. An
analysis of the data shall be done each year the process unit is in the
quality improvement program.
(6) A trial evaluation program shall be conducted at each plant site
for which the data analysis does not identify use of superior performing
pump seal technology or pumps that can be applied to the areas
identified as having poorer than average performance, except as provided
in paragraph (d)(6)(v) of this section. The trial program shall be used
to evaluate the feasibility of using in the process unit (or plant site)
the pump designs or seal technologies, and operating and maintenance
practices that have been identified by others as having low emission
performance.
(i) The trial program shall include on-line trials of pump seal
technologies or pump designs and operating and maintenance practices
that have been identified in the available literature or in analysis by
others as having the ability to perform with leak rates below 10 percent
in similar services, as having low probability of failure, or as having
no external actuating mechanism in contact with the process fluid. If
any of the candidate superior performing pump seal technologies or pumps
is not included in the performance trials, the reasons for rejecting
specific technologies from consideration shall be documented as required
in Sec. 63.181(h)(5)(ii).
(ii) The number of pump seal technologies or pumps in the trial
evaluation program shall be the lesser of 1 percent or two pumps for
programs involving single process units and the lesser of 1 percent or
five pumps for programs involving a plant site or groups of process
units. The minimum number of pumps or pump seal technologies in a trial
program shall be one.
(iii) The trial evaluation program shall specify and include
documentation of:
(A) The candidate superior performing pump seal designs or
technologies to be evaluated, the stages for evaluating the identified
candidate pump designs or pump seal technologies, including the time
period necessary to test the applicability;
(B) The frequency of monitoring or inspection of the equipment;
(C) The range of operating conditions over which the component will
be evaluated; and
(D) Conclusions regarding the emission performance and the
appropriate operating conditions and services for the trial pump seal
technologies or pumps.
(iv) The performance trials shall initially be conducted, at least,
for a 6-month period beginning not later than 18 months after the start
of the quality improvement program. No later than 24 months after the
start of the quality improvement program, the owner or operator shall
have identified pump seal technologies or pump designs that, combined
with appropriate process, operating, and maintenance practices, operate
with low emission performance for specific applications in the process
unit. The owner or operator shall continue to conduct performance trials
as long as no superior performing design or technology has been
identified, except as provided in paragraph (d)(6)(vi) of this section.
The initial list of superior emission performance pump designs or pump
seal technologies shall be amended in the future, as appropriate, as
additional information and experience is obtained.
(v) Any plant site with fewer than 400 valves and owned by a
corporation with fewer than 100 employees shall be exempt from trial
evaluations of pump seals or pump designs. Plant sites exempt from the
trial evaluations of pumps shall begin the pump seal or pump replacement
program at the start of the fourth year of the quality improvement
program.
[[Page 412]]
(vi) An owner or operator who has conducted performance trials on
all alternative superior emission performance technologies suitable for
the required applications in the process unit may stop conducting
performance trials provided that a superior performing design or
technology has been demonstrated or there are no technically feasible
alternative superior technologies remaining. The owner or operator shall
prepare an engineering evaluation documenting the physical, chemical, or
engineering basis for the judgment that the superior emission
performance technology is technically infeasible or demonstrating that
it would not reduce emissions.
(7) Each owner or operator shall prepare and implement a pump
quality assurance program that details purchasing specifications and
maintenance procedures for all pumps and pump seals in the process unit.
The quality assurance program may establish any number of categories, or
classes, of pumps as needed to distinguish among operating conditions
and services associated with poorer than average emission performance as
well as those associated with better than average emission performance.
The quality assurance program shall be developed considering the
findings of the data analysis required under paragraph (d)(5) of this
section, if applicable, the findings of the trial evaluation required in
paragraph (d)(6) of this section, and the operating conditions in the
process unit. The quality assurance program shall be updated each year
as long as the process unit has the greater of either 10 percent or more
leaking pumps or has three leaking pumps.
(i) The quality assurance program shall:
(A) Establish minimum design standards for each category of pumps or
pump seal technology. The design standards shall specify known critical
parameters such as tolerance, manufacturer, materials of construction,
previous usage, or other applicable identified critical parameters;
(B) Require that all equipment orders specify the design standard
(or minimum tolerances) for the pump or the pump seal;
(C) Provide for an audit procedure for quality control of purchased
equipment to ensure conformance with purchase specifications. The audit
program may be conducted by the owner or operator of the plant site or
process unit or by a designated representative; and
(D) Detail off-line pump maintenance and repair procedures. These
procedures shall include provisions to ensure that rebuilt or
refurbished pumps and pump seals will meet the design specifications for
the pump category and will operate such that emissions are minimized.
(ii) The quality assurance program shall be established no later
than the start of the third year of the quality improvement program for
plant sites with 400 or more valves or 100 or more employees; and no
later than the start of the fourth year of the quality improvement
program for plant sites with less than 400 valves and less than 100
employees.
(8) Beginning at the start of the third year of the quality
improvement program for plant sites with 400 or more valves or 100 or
more employees and at the start of the fourth year of the quality
improvement program for plant sites with less than 400 valves and less
than 100 employees, the owner or operator shall replace, as described in
paragraphs (d)(8)(i) and (d)(8)(ii) of this section, the pumps or pump
seals that are not superior emission performance technology with pumps
or pump seals that have been identified as superior emission performance
technology and that comply with the quality assurance standards for the
pump category. Superior emission performance technology is that category
or design of pumps or pump seals with emission performance which, when
combined with appropriate process, operating, and maintenance practices,
will result in less than 10 percent leaking pumps for specific
applications in the process unit or plant site. Superior emission
performance technology includes material or design changes to the
existing pump, pump seal, seal support system, installation of multiple
mechanical seals or equivalent, or pump replacement.
(i) Pumps or pump seals shall be replaced at the rate of 20 percent
per year based on the total number of
[[Page 413]]
pumps in light liquid service. The calculated value shall be rounded to
the nearest nonzero integer value. The minimum number of pumps or pump
seals shall be one. Pump replacement shall continue until all pumps
subject to the requirements of Sec. 63.163 of this subpart are pumps
determined to be superior performance technology.
(ii) The owner or operator may delay replacement of pump seals or
pumps with superior technology until the next planned process unit
shutdown, provided the number of pump seals and pumps replaced is
equivalent to the 20 percent or greater annual replacement rate.
(iii) The pumps shall be maintained as specified in the quality
assurance program.
Sec. 63.177 Alternative means of emission limitation: General.
(a) Permission to use an alternative means of emission limitation

demonstrated emission reduction for the required work practices and will
consider the commitment in paragraph (c)(4) of this section.
(6) The Administrator may condition the permission on requirements
that may be necessary to ensure operation and maintenance to achieve the
same or greater emission reduction as the required work practices of
this subpart.
(d) An owner or operator may offer a unique approach to demonstrate
the alternative means of emission limitation.

an organic HAP may apply to the Administrator for permission for an
alternative means of emission limitation that achieves a reduction in
emissions of the organic HAP achieved by the equipment, design, and
operational requirements of this subpart.
(2) The Administrator will grant permission according to the
provisions of paragraphs (b), (c), and (d) of this section.
Sec. 63.178 Alternative means of emission limitation: Batch processes.
(a) As an alternative to complying with the requirements of
Sec. Sec. 63.163 through 63.171 and Sec. Sec. 63.173 through 63.176,
an owner or operator of a batch process that operates in organic HAP
service during the calendar year may
[[Page 414]]
comply with one of the standards specified in paragraphs (b) and (c) of
this section, or the owner or operator may petition for approval of an
alternative standard under the provisions of Sec. 63.177 of this
subpart. The alternative standards of this section provide the options
of pressure testing or monitoring the equipment for leaks. The owner or
operator may switch among the alternatives provided the change is
documented as specified in Sec. 63.181.
(b) The following requirements shall be met if an owner or operator
elects to use pressure testing of batch product-process equipment to
demonstrate compliance with this subpart. An owner or operator who
complies with the provisions of this paragraph is exempt from the
monitoring provisions of Sec. 63.163, Sec. Sec. 63.168 and 63.169, and
Sec. Sec. 63.173 through 63.176 of this subpart.
(1) Each time equipment is reconfigured for production of a
different product or intermediate, the batch product-process equipment
train shall be pressure-tested for leaks before organic HAP is first fed
to the equipment and the equipment is placed in organic HAP service.
(i) When the batch product-process train is reconfigured to produce
a different product, pressure testing is required only for the new or
disturbed equipment.
(ii) Each batch product process that operates in organic HAP service
during a calendar year shall be pressure tested at least once during
that calendar year.
(iii) Pressure testing is not required for routine seal breaks, such
as changing hoses or filters, which are not part of the reconfiguration
to produce a different product or intermediate.
(2) The batch product process equipment shall be tested either using
the procedures specified in Sec. 63.180(f) of this subpart for pressure
or vacuum loss or with a liquid using the procedures specified in Sec.
63.180(g) of this subpart.
(3)(i) For pressure or vacuum tests, a leak is detected if the rate
of change in pressure is greater than 6.9 kilopascals (1 psig) in 1 hour
or if there is visible, audible, or olfactory evidence of fluid loss.
(ii) For pressure tests using a liquid, a leak is detected if there
are indications of liquids dripping or if there is other evidence of
fluid loss.
(4)(i) If a leak is detected, it shall be repaired and the batch
product-process equipment shall be retested before start-up of the
process.
(ii) If a batch product-process fails the retest or the second of
two consecutive pressure tests, it shall be repaired as soon as
practicable, but not later than 30 calendar days after the second
pressure test, provided the conditions specified in paragraph (d) of
this section are met.
(c) The following requirements shall be met if an owner or operator
elects to monitor the equipment to detect leaks by the method specified
in Sec. 63.180(b) of this subpart to demonstrate compliance with this
subpart.
(1) The owner or operator shall comply with the requirements of
Sec. Sec. 63.163 through 63.170, and Sec. Sec. 63.172 through 63.176
of this subpart.
(2) The equipment shall be monitored for leaks by the method
specified in Sec. 63.180(b) of this subpart when the equipment is in
organic HAP service, in use with an acceptable surrogate volatile
organic compound which is not an organic HAP, or is in use with any
other detectable gas or vapor.
(3) The equipment shall be monitored for leaks as specified below:
(i) Each time the equipment is reconfigured for the production of a
new product, the reconfigured equipment shall be monitored for leaks
within 30 days of start-up of the process. This initial monitoring of
reconfigured equipment shall not be included in determining percent
leaking equipment in the process unit.
(ii) Connectors shall be monitored in accordance with the
requirements in Sec. 63.174 of this subpart.
(iii) Equipment other than connectors shall be monitored at the
frequencies specified in table 1 of this subpart. The operating time
shall be determined as the proportion of the year the batch product-
process that is subject to the provisions of this subpart is operating.
(iv) The monitoring frequencies specified in table 1 of this subpart
are not requirements for monitoring at specific intervals and can be
adjusted to accommodate process operations. An owner
[[Page 415]]
or operator may monitor anytime during the specified monitoring period
(e.g., month, quarter, year), provided the monitoring is conducted at a
reasonable interval after completion of the last monitoring campaign.
For example, if the equipment is not operating during the scheduled
monitoring period, the monitoring can be done during the next period
when the process is operating.
(4) If a leak is detected, it shall be repaired as soon as
practicable but not later than 15 calendar days after it is detected,
except as provided in paragraph (d) of this section.
(d) Delay of repair of equipment for which leaks have been detected
is allowed if the replacement equipment is not available providing the
following conditions are met:
(1) Equipment supplies have been depleted and supplies had been
sufficiently stocked before the supplies were depleted.
(2) The repair is made no later than 10 calendar days after delivery
of the replacement equipment.
Sec. 63.179 Alternative means of emission limitation:
Enclosed-vented process units.
Process units enclosed in such a manner that all emissions from
equipment leaks are vented through a closed-vent system to a control
device meeting the requirements of Sec. 63.172 of this subpart are
exempt from the requirements of Sec. 63.163, through 63.171, and
Sec. Sec. 63.173 and 63.174 of this subpart. The enclosure shall be
maintained under a negative pressure at all times while the process unit
is in operation to ensure that all emissions are routed to a control
device.
Sec. 63.180 Test methods and procedures.
(a) Each owner or operator subject to the provisions of this subpart
shall comply with the test methods and procedures requirements provided
in this section.
(b) Monitoring, as required under this subpart, shall comply with
the following requirements:
(1) Monitoring shall comply with Method 21 of 40 CFR part 60,
appendix A.
(2)(i) Except as provided for in paragraph (b)(2)(ii) of this
section, the detection instrument shall meet the performance criteria of
Method 21 of 40 CFR part 60, appendix A, except the instrument response
factor criteria in Section 3.1.2(a) of Method 21 shall be for the
average composition of the process fluid not each individual VOC in the
stream. For process streams that contain nitrogen, water, air, or other
inerts which are not organic HAP's or VOC's, the average stream response
factor may be calculated on an inert-free basis. The response factor may
be determined at any concentration for which monitoring for leaks will
be conducted.
(ii) If no instrument is available at the plant site that will meet
the performance criteria specified in paragraph (b)(2)(i) of this
section, the instrument readings may be adjusted by multiplying by the
average response factor of the process fluid, calculated on an inert-
free basis as described in paragraph (b)(2)(i) of this section.
(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 parts per million of hydrocarbon in air);
and
(ii) Mixtures of methane in air at the concentrations specified in
paragraphs (b)(4)(ii)(A) through (b)(4)(ii)(C) of this section. A
calibration gas other than methane in air may be used if the instrument
does not respond to methane or if the instrument does not meet the
performance criteria specified in paragraph (b)(2)(i) of this section.
In such cases, the calibration gas may be a mixture of one or more of
the compounds to be measured in air.
(A) For Phase I, a mixture of methane or other compounds, as
applicable, in air at a concentration of approximately, but less than,
10,000 parts per million.
(B) For Phase II, a mixture of methane or other compounds, as
applicable, and air at a concentration of approximately, but less than,
10,000 parts per million for agitators, 5,000 parts per million for
pumps, and 500 parts per million for all other equipment, except
[[Page 416]]
as provided in paragraph (b)(4)(iii) of this section.
(C) For Phase III, a mixture of methane or other compounds, as
applicable, and air at a concentration of approximately, but less than,
10,000 parts per million methane for agitators; 2,000 parts per million
for pumps in food/medical service; 5,000 parts per million for pumps in
polymerizing monomer service; 1,000 parts per million for all other
pumps; and 500 parts per million for all other equipment, except as
provided in paragraph (b)(4)(iii) of this section.
(iii) The instrument may be calibrated at a higher methane
concentration than the concentration specified for that piece of
equipment. The concentration of the calibration gas may exceed the
concentration specified as a leak by no more than 2,000 parts per
million. If the monitoring instrument's design allows for multiple
calibration scales, then the lower scale shall be calibrated with a
calibration gas that is no higher than 2,000 parts per million above the
concentration specified as a leak and the highest scale shall be
calibrated with a calibration gas that is approximately equal to 10,000
parts per million. If only one scale on an instrument will be used
during monitoring, the owner or operator need not calibrate the scales
that will not be used during that day's monitoring.
(5) Monitoring shall be performed when the equipment is in organic
HAP service, in use with an acceptable surrogate volatile organic
compound which is not an organic HAP, or is in use with any other
detectable gas or vapor.
(6) Monitoring data that do not meet the criteria specified in
paragraphs (b)(1) through (b)(5) of this section may be used to qualify
for less frequent monitoring under the provisions in Sec. 63.168(d)(2)
and (d)(3) or Sec. 63.174(b)(3)(ii) or (b)(3)(iii) of this subpart
provided the data meet the conditions specified in paragraphs (b)(6)(i)
and (b)(6)(ii) of this section.
(i) The data were obtained before April 22, 1994.
(ii) The departures from the criteria specified in paragraphs (b)(1)
through (b)(5) of this section or from the specified monitoring
frequency of Sec. 63.168(c) are minor and do not significantly affect
the quality of the data. Examples of minor departures are monitoring at
a slightly different frequency (such as every six weeks instead of
monthly or quarterly), following the performance criteria of section
3.1.2(a) of Method 21 of appendix A of 40 CFR part 60 instead of
paragraph (b)(2) of this section, or monitoring at a different leak
definition if the data would indicate the presence or absence of a leak
at the concentration specified in this subpart. Failure to use a
calibrated instrument is not considered a minor departure.
(c) When equipment is monitored for compliance as required in
Sec. Sec. 63.164(i), 63.165(a), and 63.172(f) or when equipment subject
to a leak definition of 500 ppm is monitored for leaks as required by
this subpart, the owner or operator may elect to adjust or not to adjust
the instrument readings for background. If an owner or operator elects
to not adjust instrument readings for background, the owner or operator
shall monitor the equipment according to the procedures specified in
paragraphs (b)(1) through (b)(4) of this section. In such case, all
instrument readings shall be compared directly to the applicable leak
definition to determine whether there is a leak. If an owner or operator
elects to adjust instrument readings for background, the owner or
operator shall monitor the equipment according to the procedures
specified in paragraphs (c)(1) through (c)(4) of this section.
(1) The requirements of paragraphs (b) (1) through (4) of this
section shall apply.
(2) The background level shall be determined, using the same
procedures that will be used to determine whether the equipment is
leaking.
(3) The instrument probe shall be traversed around all potential
leak interfaces as close to the interface as possible as described in
Method 21 of 40 CFR part 60, appendix A.
(4) The arithmetic difference between the maximum concentration
indicated by the instrument and the background level is compared with
500 parts per million for determining compliance.
(d)(1) Each piece of equipment within a process unit that can
reasonably be
[[Page 417]]
expected to contain equipment in organic HAP service is presumed to be
in organic HAP service unless an owner or operator demonstrates that the
piece of equipment is not in organic HAP service. For a piece of
equipment to be considered not in organic HAP service, it must be
determined that the percent organic HAP content can be reasonably
expected not to exceed 5 percent by weight on an annual average basis.
For purposes of determining the percent organic HAP content of the
process fluid that is contained in or contacts equipment, Method 18 of
40 CFR part 60, appendix A shall be used.
(2)(i) An owner or operator may use good engineering judgment rather
than the procedures in paragraph (d)(1) of this section to determine
that the percent organic HAP content does not exceed 5 percent by
weight. When an owner or operator and the Administrator do not agree on
whether a piece of equipment is not in organic HAP service, however, the
procedures in paragraph (d)(1) of this section shall be used to resolve
the disagreement.
(ii) Conversely, the owner or operator may determine that the
organic HAP content of the process fluid does not exceed 5 percent by
weight by, for example, accounting for 98 percent of the content and
showing that organic HAP is less than 3 percent.
(3) If an owner or operator determines that a piece of equipment is
in organic HAP service, the determination can be revised after following
the procedures in paragraph (d)(1) of this section, or by documenting
that a change in the process or raw materials no longer causes the
equipment to be in organic HAP service.
(4) Samples used in determining the percent organic HAP content
shall be representative of the process fluid that is contained in or
contacts the equipment.
(e) When a flare is used to comply with Sec. 63.172(d), the owner
or operator shall comply with paragraphs (e)(1) through (3) of this
section. The owner or operator is not required to conduct a performance
test to determine percent emission reduction or outlet organic HAP or
TOC concentration.
(1) Conduct a visible emission test using the techniques specified
in Sec. 63.11(b)(4).
(2) Determine the net heating value of the gas being combusted using
the techniques specified in Sec. 63.11(b)(6).
(3) Determine the exit velocity using the techniques specified in
either Sec. 63.11(b)(7)(i) (and Sec. 63.11(b)(7)(iii), where
applicable) or Sec. 63.11(b)(8), as appropriate.
(f) The following procedures shall be used to pressure test batch
product-process equipment for pressure or vacuum loss to demonstrate
compliance with the requirements of Sec. 63.178(b)(3)(i) of this
subpart.
(1) The batch product-process equipment train shall be pressurized
with a gas to a pressure less than the set pressure of any safety relief
devices or valves or to a pressure slightly above the operating pressure
of the equipment, or alternatively, the equipment shall be placed under
a vacuum.
(2) Once the test pressure is obtained, the gas source or vacuum
source shall be shut off.
(3) The test shall continue for not less than 15 minutes unless it
can be determined in a shorter period of time that the allowable rate of
pressure drop or of pressure rise was exceeded. The pressure in the
batch product-process equipment shall be measured after the gas or
vacuum source is shut off and at the end of the test period. The rate of
change in pressure in the batch product-process equipment shall be
calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR22AP94.294
where:
[Delta] P/t = Change in pressure, psig/hr.
Pf = Final pressure, psig.
Pi = Initial pressure, psig.
tf-ti = Elapsed time, hours.
(4) The pressure shall be measured using a pressure measurement
device (gauge, manometer, or equivalent) which has a precision of 2.5 millimeter mercury in the range of test pressure and
is capable of measuring pressures up to the relief set pressure of the
pressure relief device. If such a pressure measurement device is not
reasonably
[[Page 418]]
available, the owner or operator shall use a pressure measurement device
with a precision of at least + 10 percent of the test pressure of the
equipment and shall extend the duration of the test for the time
necessary to detect a pressure loss or rise that equals a rate of one
psig per hour.
(5) An alternative procedure may be used for leak testing the
equipment if the owner or operator demonstrates the alternative
procedure is capable of detecting a pressure loss or rise.
(g) The following procedures shall be used to pressure-test batch
product-process equipment using a liquid to demonstrate compliance with
the requirements of Sec. 63.178(b)(3)(ii) of this subpart.
(1) The batch product-process equipment train, or section of the
train, shall be filled with the test liquid (e.g., water, alcohol) until
normal operating pressure is obtained. Once the equipment is filled, the
liquid source shall be shut off.
(2) The test shall be conducted for a period of at least 60 minutes,
unless it can be determined in a shorter period of time that the test is
a failure.
(3) Each seal in the equipment being tested shall be inspected for
indications of liquid dripping or other indications of fluid loss. If
there are any indications of liquids dripping or of fluid loss, a leak
is detected.
(4) An alternative procedure may be used for leak testing the
equipment, if the owner or operator demonstrates the alternative
procedure is capable of detecting losses of fluid.

Sec. 63.181 Recordkeeping requirements.
(a) An owner or operator of more than one process unit subject to
the provisions of this subpart may comply with the recordkeeping
requirements for these process units in one recordkeeping system if the
system identifies each record by process unit and the program being
implemented (e.g., quarterly monitoring, quality improvement) for each
type of equipment. All records and information required by this section
shall be maintained in a manner that can be readily accessed at the
plant site. This could include physically locating the records at the
plant site or accessing the records from a central location by computer
at the plant site.
(b) Except as provided in paragraph (e) of this section, the
following information pertaining to all equipment in each process unit
subject to the requirements in Sec. Sec. 63.162 through 63.174 of this
subpart shall be recorded:
