EXPLANATION
The Code of Federal Regulations is a codification of the general and
permanent rules published in the Federal Register by the Executive
departments and agencies of the Federal Government. The Code is divided
into 50 titles which represent broad areas subject to Federal
regulation. Each title is divided into chapters which usually bear the
name of the issuing agency. Each chapter is further subdivided into
parts covering specific regulatory areas.
Each volume of the Code is revised at least once each calendar year
and issued on a quarterly basis approximately as follows:
Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
The appropriate revision date is printed on the cover of each
volume.
LEGAL STATUS
The contents of the Federal Register are required to be judicially
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie
evidence of the text of the original documents (44 U.S.C. 1510).
HOW TO USE THE CODE OF FEDERAL REGULATIONS
The Code of Federal Regulations is kept up to date by the individual
issues of the Federal Register. These two publications must be used
together to determine the latest version of any given rule.
To determine whether a Code volume has been amended since its
revision date (in this case, July 1, 2000), consult the ``List of CFR
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative
List of Parts Affected,'' which appears in the Reader Aids section of
the daily Federal Register. These two lists will identify the Federal
Register page number of the latest amendment of any given rule.
EFFECTIVE AND EXPIRATION DATES
Each volume of the Code contains amendments published in the Federal
Register since the last revision of that volume of the Code. Source
citations for the regulations are referred to by volume number and page
number of the Federal Register and date of publication. Publication
dates and effective dates are usually not the same and care must be
exercised by the user in determining the actual effective date. In
instances where the effective date is beyond the cut-off date for the
Code a note has been inserted to reflect the future effective date. In
those instances where a regulation published in the Federal Register
states a date certain for expiration, an appropriate note will be
inserted following the text.
OMB CONTROL NUMBERS
The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires
Federal agencies to display an OMB control number with their information
collection request.
[[Page vi]]
Many agencies have begun publishing numerous OMB control numbers as
amendments to existing regulations in the CFR. These OMB numbers are
placed as close as possible to the applicable recordkeeping or reporting
requirements.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For
the period beginning January 1, 1986, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume.
INCORPORATION BY REFERENCE
What is incorporation by reference? Incorporation by reference was
established by statute and allows Federal agencies to meet the
requirement to publish regulations in the Federal Register by referring
to materials already published elsewhere. For an incorporation to be
valid, the Director of the Federal Register must approve it. The legal
effect of incorporation by reference is that the material is treated as
if it were published in full in the Federal Register (5 U.S.C. 552(a)).
This material, like any other properly issued regulation, has the force
of law.
What is a proper incorporation by reference? The Director of the
Federal Register will approve an incorporation by reference only when
the requirements of 1 CFR part 51 are met. Some of the elements on which
approval is based are:
(a) The incorporation will substantially reduce the volume of
material published in the Federal Register.
(b) The matter incorporated is in fact available to the extent
necessary to afford fairness and uniformity in the administrative
process.
(c) The incorporating document is drafted and submitted for
publication in accordance with 1 CFR part 51.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume as an approved incorporation by
reference, please contact the agency that issued the regulation
containing that incorporation. If, after contacting the agency, you find
the material is not available, please notify the Director of the Federal
Register, National Archives and Records Administration, Washington DC
20408, or call (202) 523-4534.
CFR INDEXES AND TABULAR GUIDES
A subject index to the Code of Federal Regulations is contained in a
separate volume, revised annually as of January 1, entitled CFR Index
and Finding Aids. This volume contains the Parallel Table of Statutory
Authorities and Agency Rules (Table I). A list of CFR titles, chapters,
and parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
An index to the text of ``Title 3--The President'' is carried within
that volume.
The Federal Register Index is issued monthly in cumulative form.
This index is based on a consolidation of the ``Contents'' entries in
the daily Federal Register.
A List of CFR Sections Affected (LSA) is published monthly, keyed to
the revision dates of the 50 CFR titles.

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 (including those requirements in part 60 of
this chapter), or a standard issued under State authority.
(4) The provisions of this subpart (i.e., subpart A of this part)
apply to owners or operators who are subject to subsequent subparts of
this part, except when otherwise specified in a particular subpart or in
a relevant standard. The general provisions in subpart
[[Page 15]]
A eliminate the repetition of requirements applicable to all owners or
operators affected by this part. The general provisions in subpart A do
not apply to regulations developed pursuant to section 112(r) of the
amended Act, unless otherwise specified in those regulations.
(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) Subpart D of this part contains regulations that address
procedures for an owner or operator to obtain an extension of compliance
with a relevant standard through an early reduction of emissions of
hazardous air pollutants pursuant to section 112(i)(5) of the Act.
(8) Subpart E of this part contains regulations that provide for the
establishment of procedures consistent with section 112(l) of the Act
for the approval of State rules or programs to implement and enforce
applicable Federal rules promulgated under the authority of section 112.
Subpart E also establishes procedures for the review and withdrawal of
section 112 implementation and enforcement authorities granted through a
section 112(l) approval.
(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).
(13) Special provisions set forth under an applicable subpart of
this part or in a relevant standard established under this part shall
supersede any conflicting provisions of this subpart.
(14) Any standards, limitations, prohibitions, or other federally
enforceable requirements established pursuant to procedural regulations
in this part [including, but not limited to, equivalent emission
limitations established pursuant to section 112(g) of the Act] shall
have the force and effect of requirements promulgated in this part and
shall be subject to the provisions of this subpart, except when
explicitly specified otherwise.
(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) In addition to complying with the provisions of this part, the
owner or
[[Page 16]]
operator of any such source may be required to obtain an operating
permit issued to stationary sources by an authorized State air pollution
control agency or by the Administrator of the U.S. Environmental
Protection Agency (EPA) pursuant to title V of the Act (42 U.S.C. 7661).
For more information about obtaining an operating permit, see part 70 of
this chapter.
(3) An owner or operator of a stationary source that emits (or has
the potential to emit, without considering controls) one or more
hazardous air pollutants who determines that the source is not subject
to a relevant standard or other requirement established under this part,
shall keep a record of the applicability determination as specified in
Sec. 63.10(b)(3) of this subpart.
(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 shall
comply with the provisions of this subpart and the provisions of that
standard, except as specified otherwise in this subpart or that
standard.
(2) 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 the permitting authority in the State in which the
source is located. Emission standards promulgated in this part for area
sources 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) Area sources affected by that emission standard are
immediately subject to the requirement to apply for and obtain a title V
permit in all States. If a standard fails to specify what the permitting
requirements will be for area sources affected by that standard, then
area sources that are subject to the standard will be subject to the
requirement to obtain a title V permit without deferral. If the owner or
operator is required to obtain a title V permit, he or she shall apply
for such permit in accordance with part 70 of this chapter and
applicable State regulations, or in accordance with the regulations
contained in this chapter to implement the Federal title V permit
program (42 U.S.C. 7661), whichever regulations are applicable.
(3) [Reserved]
(4) If the owner or operator of an existing source obtains an
extension of compliance for such source in accordance with the
provisions of subpart D of this part, the owner or operator shall comply
with all requirements of this subpart except those requirements that are
specifically overridden in the extension of compliance for that source.
(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) Applicability of permit program before a relevant standard has
been set under this part. After the effective date of an approved permit
program in the State in which a stationary source is (or would be)
located, the owner or operator of such source may be required to obtain
a title V permit from the permitting authority in that State (or revise
such a permit if one has already been issued to the source) before a
relevant standard is established under this part. If the owner or
operator is required to obtain (or revise) a title V permit, he/she
shall apply to obtain (or revise) such permit in accordance with the
regulations contained in part 70 of this chapter and applicable State
regulations, or the regulations codified in this chapter to implement
the Federal title V permit program (42 U.S.C. 7661), whichever
regulations are applicable.

source that is regulated by a relevant standard or other requirement
established pursuant to section 112 of the Act. Each relevant standard
will define the ``affected source'' for the purposes of that standard.
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. Sources regulated under part 60
or part 61 of this chapter are not affected sources for the purposes of
part 63.

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, 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.

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 a
stationary 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.

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

limitation or equivalent emission limitation becomes effective according
to the provisions of this part. The effective date of a permit program
established under title V of the Act (42 U.S.C. 7661) is determined
according to the regulations in this chapter establishing such programs.
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.
[[Page 19]]
Equivalent emission limitation means the maximum achievable control
technology emission limitation (MACT emission limitation) for hazardous
air pollutants that the Administrator (or a State with an approved
permit program) determines on a case-by-case basis, pursuant to section
112(g) or section 112(j) of the Act, to be equivalent to the emission

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 means the replacement of components of an affected or
a previously unaffected stationary 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

program is effective in the State in which an affected source is (or
would be) located, no person may construct a new affected source or
reconstruct an affected source subject to such standard, or reconstruct
a source such that the source becomes an affected source subject to the
standard, without notifying the Administrator of the intended
construction or reconstruction. The notification shall be submitted in
accordance with the procedures in Sec. 63.9(b) and shall include all the
information required for an application for approval of construction or
reconstruction as specified in paragraph (d) of this section. For major
sources, the application for approval of construction or reconstruction
may be used to fulfill the notification requirements of this paragraph.
(5) After the effective date of any relevant standard promulgated by
the Administrator under this part, whether or not an approved permit
program is effective in the State in which an affected source is
located, no person may operate such source without complying with the
provisions of this subpart and the relevant standard unless that person
has received an extension of compliance or an exemption from compliance
under Sec. 63.6(i) or Sec. 63.6(j) of this subpart.
(6) After the effective date of any relevant standard promulgated by
the Administrator under this part, whether or not an approved permit
program is effective in the State in which an affected source is
located, 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 shall be considered part of the affected source and
subject to all provisions of the relevant standard established for that
affected source. If a new affected source is added to the facility, the
new affected source shall be subject to all the provisions of the
relevant standard that are established for new sources including
compliance dates.
(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 shall
submit to the Administrator an application for approval of the
construction of a new major affected source, the reconstruction of a
major affected source, or the reconstruction of a major source such that
the source becomes a major affected source subject to the standard. The
application shall be submitted as soon as practicable before the
construction or reconstruction is planned to commence (but no sooner
than the effective date of the relevant standard) if the construction or
reconstruction commences after the effective date of a relevant standard
promulgated in this part. The application shall be submitted as soon as
practicable before startup but no later than 60 days after the effective
date of a relevant standard promulgated in this part if the construction
or reconstruction had commenced and initial startup had not occurred
before the standard's effective date. The application for approval of
construction or reconstruction may be used to fulfill the initial
notification requirements of Sec. 63.9(b)(5) of this subpart. The owner
or operator may submit the application for approval well in advance of
the date construction or reconstruction is planned to commence in order
to ensure a timely review by the Administrator and that the planned
commencement date 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;
(C) The address (i.e., physical location) or proposed address of the
source;
[[Page 25]]
(D) An identification of the relevant standard that is the basis of
the application;

source, reported in units and averaging times and in accordance with the
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 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 shall 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 point of emission for each hazardous air pollutant that is emitted
(or could 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
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 include calculations of emission estimates
in sufficient detail to permit assessment of the validity of the
calculations. An owner or operator who submits approximations of control
efficiencies under this subparagraph shall submit the actual control
efficiencies as specified in paragraph (d)(1)(iii) of this section.
(3) Application for approval of reconstruction. Each application for
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
include calculations of emission estimates in sufficient detail to
permit assessment of the validity of the calculations;
(iii) An estimate of the fixed capital cost of the replacements and
of constructing a comparable entirely new source;
(iv) The estimated life of the affected source after the
replacements; and
(v) A discussion of any economic or technical limitations the source
may have in complying with relevant standards or other requirements
after the proposed replacements. The discussion shall be sufficiently
detailed to demonstrate to the Administrator's satisfaction that the
technical or economic limitations affect the source's ability
[[Page 26]]
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 subparagraphs (d)(3) (iii) through (v) of this section,
above.
(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 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
(ii) Notice of opportunity for the applicant to present, in writing,
within 30 calendar days after he/she is notified of the intended denial,
additional information or arguments to the Administrator to enable
further action on the application.
(4) A final determination to deny any application for approval will
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
[[Page 27]]
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) The Administrator may 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 or reconstructed
source who is subject to such requirement demonstrates to the
Administrator's satisfaction that the following conditions have been (or
will be) met:
(i) The owner or operator of the new or reconstructed source has
undergone a preconstruction review and approval process in the State in
which the source is (or would be) located before the promulgation date
of the relevant standard and has received a federally enforceable
construction permit that contains a finding that the source will meet
the relevant emission standard as proposed, if the source is properly
built and operated;
(ii) In making its finding, the State has considered factors
substantially equivalent to those specified in paragraph (e)(1) of this
section; and either
(iii) The promulgated standard is no more stringent than the
proposed standard in any relevant aspect that would affect the
Administrator's decision to approve or disapprove an application for
approval of construction or reconstruction under this section; or
(iv) The promulgated standard is more stringent than the proposed
standard but the owner or operator will comply with the standard as
proposed during the 3-year period immediately following the effective
date of the standard as allowed for in Sec. 63.6(b)(3) of this subpart.
(2) The owner or operator shall submit to the Administrator the
request for approval of construction or reconstruction under this
paragraph no later than the application deadline specified in paragraph
(d)(1) of this section (see also Sec. 63.9(b)(2) of this subpart). The
owner or operator shall 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.
Sec. 63.6 Compliance with standards and maintenance requirements.
(a) Applicability. (1) The requirements in this section apply to
owners or operators of affected sources for which any relevant standard
has been established pursuant to section 112 of the Act unless--
(i) The Administrator (or a State with an approved permit program)
has granted an extension of compliance consistent with paragraph (i) of
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 (b)(4) of this section, the owner
or operator of a new or reconstructed source that has an initial startup
before the effective date of a relevant standard established under this
part pursuant to section 112(d), 112(f), or 112(h) of the Act shall
comply with such standard not later than the standard's effective date.
(2) Except as specified in paragraphs (b)(3) and (b)(4) of this
section, the owner or operator of a new or reconstructed source that has
an initial startup after the effective date of a relevant standard
established under this part pursuant to section 112(d), 112(f), or
112(h) of the Act shall comply with such standard upon startup of the
source.
(3) The owner or operator of an affected source for which
construction or
[[Page 28]]
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; 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 comply with the emission standard under section
112(f) not later than 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 shall comply with the standard as
provided in paragraphs (b)(1) and (b)(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 paragraph (b)(4) of this
section shall notify the Administrator in accordance with Sec. 63.9(d)
of this subpart.
(6) [Reserved]
(7) After the effective date of an emission standard promulgated
under this part, the owner or operator of an unaffected new area source
(i.e., an area source for which construction or reconstruction was
commenced after the proposal date of the standard) that increases its
emissions of (or its potential to emit) hazardous air pollutants such
that the source becomes a major source that is subject to the emission
standard, shall comply with the relevant emission standard immediately
upon becoming a major source. This compliance date shall apply to new
area sources that become affected major sources regardless of whether
the new area source previously was affected by that standard. The new
affected major source shall comply with all requirements of that
standard that affect new sources.
(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) After the effective date of a relevant standard established
under this part pursuant to section 112(f) of the Act, the owner or
operator of an existing source shall comply with such standard not later
than 90 days after the standard's effective date unless the
Administrator has granted an extension to the source under paragraph
(i)(4)(ii) of this section.
(3)-(4) [Reserved]
(5) After the effective date of an emission standard promulgated
under this part, the owner or operator of an unaffected existing area
source that increases its emissions of (or its potential to emit)
hazardous air pollutants such that the source becomes a major source
that is subject to the emission standard shall comply by the date
specified in the standard for existing area sources that become major
sources. If no such compliance date is specified in the standard, the
source shall have a period of time to comply with the relevant emission
standard that is equivalent to the compliance period specified in that
standard for other existing sources. This compliance period shall apply
to existing area sources that become affected major sources regardless
of whether the existing area source previously was affected by that
standard. Notwithstanding the previous two sentences, however, if the
existing area source becomes a major source by the addition of a new
affected source or by reconstructing, the portion of the existing
facility that is a new affected
[[Page 29]]
source or a reconstructed source shall comply with all requirements of
that standard that affect new sources, including the compliance date for
new sources.
(d) [Reserved]
(e) Operation and maintenance requirements. (1)(i) At all times,
including periods of startup, shutdown, and malfunction, owners or
operators shall operate and maintain any affected source, including
associated air pollution control equipment, in a manner consistent with
good air pollution control practices for minimizing emissions at least
to the levels required by all relevant standards.
(ii) Malfunctions shall be corrected as soon as practicable after
their occurrence in accordance with the startup, shutdown, and
malfunction plan required in paragraph (e)(3) of this section.
(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) Determination of whether acceptable 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.
(3) Startup, shutdown, and malfunction plan. (i) The owner or
operator of an affected source shall develop and implement 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 and air pollution control equipment used to
comply with the relevant standard. As required under Sec. 63.8(c)(1)(i),
the plan shall identify all routine or otherwise predictable CMS
malfunctions. This plan shall be developed by the owner or operator by
the source's compliance date for that relevant standard. The plan shall
be incorporated by reference into the source's title V permit. The
purpose of the startup, shutdown, and malfunction plan is to--
(A) Ensure that, at all times, owners or operators operate and
maintain affected sources, including associated air pollution control
equipment, in a manner consistent with good air pollution control
practices for minimizing emissions at least to the levels required by
all relevant standards;
(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) During periods of startup, shutdown, and malfunction, the owner
or operator of an affected source shall operate and maintain such source
(including associated air pollution control equipment) in accordance
with the procedures specified in the startup, shutdown, and malfunction
plan developed under paragraph (e)(3)(i) of this section.
(iii) When actions taken by the owner or operator during a startup,
shutdown, 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 shall keep records for that event that 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 for that event. In addition, the owner or operator shall keep
records of these events as specified in Sec. 63.10(b) (and elsewhere in
this part), including records of the occurrence and duration of each
startup, shutdown, or malfunction of operation and each malfunction of
the air pollution control equipment. Furthermore, the owner or operator
[[Page 30]]
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, the owner or
operator shall record the actions taken for that event and shall 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 (see Sec. 63.10(d)(5)(ii))).
(v) The owner or operator shall keep the written startup, shutdown,
and malfunction plan on record after it is developed to be made
available for inspection, upon request, by the Administrator for the
life of the affected source or until the affected source is no longer
subject to the provisions of this part. In addition, if the startup,
shutdown, and malfunction plan is revised, the owner or operator shall
keep previous (i.e., superseded) versions of the startup, shutdown, and
malfunction 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.
(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 when requested by the
Administrator.
(vii) Based on the results of a determination made under paragraph
(e)(2) 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 may require
reasonable 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 equipment) during a startup, shutdown,
or malfunction event in a manner consistent with good air pollution
control practices for minimizing emissions at least to the levels
required by all relevant standards; or
(C) Does not provide adequate procedures for correcting
malfunctioning process and/or air pollution control equipment as quickly
as practicable.
(viii) 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 shall revise the startup,
shutdown, and malfunction plan within 45 days after the event to include
detailed 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 equipment.
(f) Compliance with nonopacity emission standards--(1)
Applicability. The nonopacity 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.
(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
[[Page 31]]
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) of this subpart.
(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 an affected source's compliance with a nonopacity emission
standard, as specified in paragraphs (f)(1) and (f)(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 any
information available to the Administrator needed to determine whether
proper operation and maintenance practices are being used.
(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.
[[Page 32]]
(h) Compliance with opacity and visible emission standards--(1)
Applicability. The opacity and visible 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.
(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]
(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) of this subpart; 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
[[Page 33]]
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.
(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
[[Page 34]]
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 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
[[Page 35]]
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 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 shall be submitted in writing to the
appropriate authority not later than 12 months before the affected
source's compliance date (as specified in paragraphs (b) and (c) of this
section) for sources that are not including emission points in an
emissions average, or not later than 18 months before the affected
source's compliance date (as specified in paragraphs (b) and (c) of this
section) for sources that are including emission points in an emissions
average. 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, e.g., a compliance date specified by the
standard is less than 12 (or 18) months after the standard's effective
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 shall be submitted in
writing to the Administrator not later than 15 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
[[Page 36]]
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 compliance will be reached. At a minimum, the list of dates shall
include:
(1) The date by which contracts for emission control systems or
process changes for emission control will be awarded, or the date by
which orders will be issued for the purchase of component parts to
accomplish emission control or process changes;
(2) The date by which on-site construction, installation of emission
control equipment, or a process change is to be initiated;
(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) A description of interim emission control steps that will be
taken during the extension period, including milestones to assure proper
operation and maintenance of emission control and process equipment; and
(D) Whether the owner or operator is also requesting an extension of
other applicable requirements (e.g., performance testing requirements).
(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
[[Page 37]]
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 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 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.
(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
[[Page 38]]
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 paragraphs (i)(10)(iii) or
(i)(10)(iv) of this section is not met.
(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.
Sec. 63.7 Performance testing requirements.
(a) Applicability and performance test dates. (1) Unless otherwise
specified, this section applies to the owner or operator of an affected
source required to do performance testing, or another form of compliance
demonstration, under a relevant standard.
(2) 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 shall perform such
tests as follows--
(i) Within 180 days after the effective date of a relevant standard
for a new source that has an initial startup date before the effective
date; or
(ii) Within 180 days after initial startup for a new source that has
an initial startup date after the effective date of a relevant standard;
or
(iii) Within 180 days after the compliance date specified in an
applicable subpart of this part for an existing source subject to an
emission standard established pursuant to section 112(d) of the Act, or
within 180 days after startup of an existing source if the source begins
operation after the effective date of the relevant emission standard; or
(iv) Within 180 days after the compliance date for an existing
source subject to an emission standard established pursuant to section
112(f) of the Act; or
(v) Within 180 days after the termination date of the source's
extension of compliance for an existing source that obtains an extension
of compliance under Sec. 63.6(i); or
(vi) Within 180 days after the compliance date for a new source,
subject to an emission standard established pursuant to section 112(f)
of the Act, 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 the relevant standard
established pursuant to section 112(f) [see Sec. 63.6(b)(4)]; or
(vii) [Reserved]; or
(viii) [Reserved]; or
(ix) 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
[[Page 39]]
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.
(b) Notification of performance test. (1) 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, upon request, to review and approve the site-specific
test plan required under paragraph (c) of this section and to have an
observer present during the test. Observation of the performance test by
the Administrator is optional.
(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 shall
notify the Administrator within 5 days 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 external QA program shall include, at a minimum,
application of plans for a test method performance audit (PA) during the
performance test. The PA's consist of blind audit samples provided by
the Administrator and analyzed during the performance test in order to
provide a measure of test data bias. The external QA program may also
include 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.
(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--
[[Page 40]]
(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, the owner or
operator shall 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 shall refrain from conducting the
performance test until 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
until after the alternative method is approved (see paragraph (f) of
this section). If the Administrator does not approve the site-specific
test plan (if review is requested) or the use of the alternative method
within 30 days before the test is scheduled to begin, the performance
test dates specified in paragraph (a) of this section may be extended
such that the owner or operator shall conduct the performance test
within 60 calendar days after the Administrator approves the site-
specific test plan or after use of the alternative method is approved.
Notwithstanding the requirements in the preceding two 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.
(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.
(4)(i) Performance test method audit program. The owner or operator
shall analyze performance audit (PA) samples during each performance
test. The owner or operator shall request performance audit materials 45
days prior to the test date. Cylinder audit gases may be obtained by
contacting the Cylinder Audit Coordinator, Quality Assurance Division
(MD-77B), Atmospheric Research and Exposure Assessment Laboratory
(AREAL), U.S. EPA, Research Triangle Park, North Carolina 27711. All
other audit materials may be obtained by contacting the Source Test
Audit Coordinator, Quality Assurance Division (MD-77B), AREAL, U.S. EPA,
Research Triangle Park, North Carolina 27711.
(ii) The Administrator will have sole discretion to require any
subsequent remedial actions of the owner or operator based on the PA
results.
(iii) If the Administrator fails to provide required PA materials to
an owner or operator of an affected source in time to analyze the PA
samples during a performance test, the requirement to conduct a PA under
this paragraph shall be waived for such source for that performance
test. Waiver under this paragraph of the requirement to conduct a PA for
a particular performance test does not constitute a waiver of the
requirement to conduct a PA for future required performance tests.
(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:
[[Page 41]]
(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; or
(ii) Approves the use of an alternative test method, 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 and 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
(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 permission
to use an alternative test method 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 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 not later than with the submittal of the site-
specific test plan
[[Page 42]]
(if requested by the Administrator) or at least 60 days before the
performance test is scheduled to begin if a site-specific test plan is
not submitted;
(ii) Uses Method 301 in appendix A of this part 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 when the
Administrator approves or disapproves the site-specific test plan
required under paragraph (c) of this section. If the Administrator finds
reasonable grounds to dispute the results obtained by the Method 301
validation process, the Administrator may require the use of a test
method specified in a relevant standard.
(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 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) [Reserved]
(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.
[[Page 43]]
(3) Request to waive a performance test. (i) If a request is made
for an extension 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)(i) Unless otherwise specified in a relevant
standard, this section applies to the owner or operator of an affected
source required to do monitoring under that standard.
(ii) Relevant standards established under this part will specify
monitoring systems, methods, or procedures, monitoring frequency, and
other pertinent requirements for source(s) regulated by those standards.
This section specifies general monitoring requirements such as those
governing the conduct of monitoring and requests to use alternative
monitoring methods. In addition, this section specifies detailed
requirements that apply to affected sources required to use continuous
monitoring systems (CMS) under a relevant standard.
(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; or
(ii) Approves the use of alternatives to any monitoring requirements
or procedures.
(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 effluents from a single affected source, or from two
or
[[Page 44]]
more affected sources, are combined before being released to the
atmosphere, the owner or operator shall install an applicable CMS on
each effluent.
(ii) If the relevant standard is a mass emission standard and the
effluent from one affected source is released to the atmosphere through
more than one point, the owner or operator shall 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 shall ensure the
immediate repair or replacement of CMS parts to correct ``routine'' or
otherwise predictable CMS malfunctions as defined in the source's
startup, shutdown, and malfunction plan required by Sec. 63.6(e)(3). The
owner or operator shall keep the necessary parts for routine repairs of
the affected equipment readily available. If the plan is followed and
the CMS repaired immediately, this action shall be reported in the
semiannual startup, shutdown, and malfunction report required under
Sec. 63.10(d)(5)(i).
(ii) For those malfunctions or other events that affect the CMS and
are not addressed by the startup, shutdown, and malfunction plan, the
owner or operator shall report actions that are not consistent with the
startup, shutdown, and malfunction plan within 24 hours after commencing
actions inconsistent with the plan. The owner or operator shall send a
follow-up report within 2 weeks after commencing actions inconsistent
with the plan that either certifies that corrections have been made or
includes a corrective action plan and schedule. The owner or operator
shall provide proof that repair parts have been ordered or any other
records that would indicate that the delay in making repairs is beyond
his or her control.
(iii) The Administrator's determination of whether acceptable
operation and maintenance procedures are being used will be based on
information that may include, but is not limited to, review of operation
and maintenance procedures, operation and maintenance records,
manufacturing recommendations and specifications, and inspection of the
CMS. Operation and maintenance procedures written by the CMS
manufacturer and other guidance also can be used to maintain and operate
each CMS.
(2) All CMS shall be installed such that representative measurements
of emissions or process parameters from the affected source are
obtained. In addition, CEMS shall be located according to procedures
contained in the applicable performance specification(s).
(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
[[Page 45]]
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 installed in accordance with the
provisions of this part and the applicable CMS performance
specification(s) shall check 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 (e)(3)(ii) of this section. The zero (low-
level) and high-level calibration drifts shall 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 must 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 shall be cleaned
prior to performing the zero (low-level) and high-level drift
adjustments; the optical surfaces and instrumental surfaces shall be
cleaned when the cumulative automatic zero compensation, if applicable,
exceeds 4 percent opacity.
(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.
[[Page 46]]
(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
(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
[[Page 47]]
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 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' 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 simultaneously with the
results of the performance test required under Sec. 63.7 or within 60
days of completion of the performance evaluation if no test is required,
unless otherwise specified in a relevant standard. The Administrator may
request that the owner or operator submit the raw data from a
performance evaluation in the report of the performance evaluation
results.
(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
[[Page 48]]
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 method 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 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;
(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 method. An owner or
operator who wishes to use an alternative monitoring method shall submit
an application to the Administrator as described in paragraph (f)(4)(ii)
of this section, below. The application may be submitted at any time
provided that the monitoring method is not used to demonstrate
compliance with a relevant standard or other requirement. If the
alternative monitoring method is to be used to demonstrate compliance
with a relevant standard, the application shall be submitted not later
than with the site-specific test plan required in Sec. 63.7(c) (if
requested) or with the site-specific performance evaluation plan (if
requested) or at least 60 days before the performance evaluation is
scheduled to begin.
(ii) The application shall contain a description of the proposed
alternative monitoring system and a performance evaluation test plan, if
required, as specified in paragraph (e)(3) of this section. In addition,
the application shall 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
[[Page 49]]
by the Administrator in order to meet the compliance demonstration date
specified in this section or the relevant standard.
(5) Approval of request to use alternative monitoring method. (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. 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
[[Page 50]]
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 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.
(g) Reduction of monitoring data. (1) The owner or operator of each
CMS shall reduce the monitoring data as specified in this paragraph. In
addition, each relevant standard may contain additional requirements for
reducing monitoring data. When additional requirements are specified in
a relevant standard, the standard will identify any unnecessary or
duplicated requirements in this paragraph that the owner or operator
need not comply with.
(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
shall not be included in any data average computed under this part. For
owners or operators 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.
[59 FR 12430, Mar. 16, 1994, as amended at 64 FR 7468, Feb. 12, 1999]
Sec. 63.9 Notification requirements.
(a) Applicability and general information. (1) The requirements in
this section apply to owners and operators of affected sources that are
subject to the provisions of this part, unless specified otherwise in a
relevant standard.
(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 notice that contains all the information
required in a notification listed in this section, the owner or operator
may send the Administrator a copy of the notice sent
[[Page 51]]
to the State to satisfy the requirements of this section for that
notification.
(4)(i) Before a State has been delegated the authority to implement
and enforce notification requirements established under this part, the
owner or operator of an affected source in such State subject to such
requirements shall submit notifications 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 notification requirements established under this part, the owner
or operator of an affected source in such State subject to such
requirements shall submit notifications 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 notification 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 notifications at its discretion.
(b) Initial notifications. (1)(i) The requirements of this paragraph
apply to the owner or operator of an affected source when such source
becomes subject to a relevant standard.
(ii) 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 shall be subject to the
notification requirements of this section.
(iii) Affected sources that are required under this paragraph to
submit an initial notification may use the application for approval of
construction or reconstruction under Sec. 63.5(d) of this subpart, if
relevant, to fulfill the initial notification requirements of this
paragraph.
(2) The owner or operator of an affected source that has an initial
startup before the effective date of a relevant standard under this part
shall notify the Administrator in writing that the source is subject to
the relevant standard. The notification, which shall be submitted not
later than 120 calendar days after the effective date of the relevant
standard (or within 120 calendar days after the source becomes subject
to the relevant standard), shall provide the following information:
(i) The name and address of the owner or operator;
(ii) The address (i.e., physical location) of the affected source;
(iii) An identification of the relevant standard, or other
requirement, that is the basis of the notification and the source's
compliance date;
(iv) A brief description of the nature, size, design, and method of
operation of the source, including its operating design capacity and an
identification of each point of emission for each hazardous air
pollutant, or if a definitive identification is not yet possible, a
preliminary identification of each point of emission for each hazardous
air pollutant; and
(v) A statement of whether the affected source is a major source or
an area source.
(3) The owner or operator of a new or reconstructed affected source,
or a source that has been reconstructed such that it is an affected
source, that has an initial startup after the effective date of a
relevant standard under this part and for which an application for
approval of construction or reconstruction is not required under
Sec. 63.5(d), shall notify the Administrator in writing that the source
is subject to the relevant standard no later than 120 days after initial
startup. The notification shall provide all the information required in
paragraphs (b)(2)(i) through (b)(2)(v) of this section, delivered or
postmarked with the notification required in paragraph (b)(5).
(4) The owner or operator of a new or reconstructed major affected
source that has an initial startup after the effective date of a
relevant standard under this part and for which an application for
approval of construction or reconstruction is required under
[[Page 52]]
Sec. 63.5(d) shall provide the following information in writing to the
Administrator:
(i) A notification of intention to construct a new major affected
source, reconstruct a major affected source, or reconstruct a major
source such that the source becomes a major affected source with the
application for approval of construction or reconstruction as specified
in Sec. 63.5(d)(1)(i);
(ii) A notification of the date when construction or reconstruction
was commenced, submitted simultaneously with the application for
approval of construction or reconstruction, if construction or
reconstruction was commenced before the effective date of the relevant
standard;
(iii) A notification of the date when construction or reconstruction
was commenced, delivered or postmarked not later than 30 days after such
date, if construction or reconstruction was commenced after the
effective date of the relevant standard;
(iv) [Reserved]
(v) A notification of the actual date of startup of the source,
delivered or postmarked within 15 calendar days after that date.
(5) After the effective date of any relevant standard established by
the Administrator under this part, whether or not an approved permit
program is effective in the State in which an affected source is (or
would be) located, an owner or operator who intends to construct a new
affected source or reconstruct an affected source subject to such
standard, or reconstruct a source such that it becomes an affected
source subject to such standard, shall notify the Administrator, in
writing, of the intended construction or reconstruction. The
notification shall be submitted as soon as practicable before the
construction or reconstruction is planned to commence (but no sooner
than the effective date of the relevant standard) if the construction or
reconstruction commences after the effective date of a relevant standard
promulgated in this part. The notification shall be submitted as soon as
practicable before startup but no later than 60 days after the effective
date of a relevant standard promulgated in this part if the construction
or reconstruction had commenced and initial startup had not occurred
before the standard's effective date. The notification shall include all
the information required for an application for approval of construction
or reconstruction as specified in Sec. 63.5(d). For major sources, the
application for approval of construction or reconstruction may be used
to fulfill the requirements of this paragraph.
(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
[[Page 53]]
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 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) An analysis demonstrating whether the affected source is a major
source or an area 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 shall 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 a relevant standard, in
[[Page 54]]
which case the letter shall 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.
(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 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
[[Page 55]]
in writing within 15 calendar days after the change.
[59 FR 12430, Mar. 16, 1994, as amended at 64 FR 7468, Feb. 12, 1999]
Sec. 63.10 Recordkeeping and reporting requirements.
(a) Applicability and general information. (1) The requirements of
this section apply to owners or operators of affected sources who are
subject to the provisions of this part, unless specified otherwise in a
relevant standard.
(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 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
[[Page 56]]
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, shutdown, or
malfunction of operation (i.e., process equipment);
(ii) The occurrence and duration of each malfunction of the air
pollution control equipment;
(iii) All maintenance performed on the air pollution control
equipment;
(iv) Actions taken during periods of startup, shutdown, and
malfunction (including corrective actions to restore malfunctioning
process and air pollution control equipment to its normal or usual
manner of operation) when such actions 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 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,
shutdown, and malfunction (including corrective actions to restore
malfunctioning process and air pollution control 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
[[Page 57]]
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 is not subject to a relevant standard
or other requirement established under this part, the owner or operator
shall 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 shall 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) shall 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 shall be performed in
accordance with requirements established in 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.
(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);
[[Page 58]]
(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, 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 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, shutdown, 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. Reports shall only be required if a
startup, shutdown, or 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
[[Page 59]]
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 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, shutdown, 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 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, and whether any excess
emissions and/or parameter monitoring exceedances are believed to have
occurred. 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 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
[[Page 60]]
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]
(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. 63.8(c)(7) and Sec. 63.8(c)(8), and in
the relevant standard, and they
[[Page 61]]
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
(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;

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
[[Page 62]]
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 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. 63.6(i) and Sec. 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 requirements.
(a) Applicability. This section contains requirements for control
devices used to comply with provisions in relevant standards. These
requirements apply only to affected sources covered by relevant
standards referring directly or indirectly to this section.
(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 other equivalent device to detect the presence of a flame.
[[Page 63]]
(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 (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 (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,
[[Page 64]]
Vmax, for flares complying with this paragraph shall be
determined by the following equation:
Log10(Vmax)=(HT+28.8)/31.7
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.

Sec. 63.12 State authority and delegations.
(a) The provisions of this part shall not be construed in any manner
to preclude any State or political subdivision thereof from--
(1) Adopting and enforcing any standard, limitation, prohibition, or
other regulation applicable to an affected source subject to the
requirements of this part, provided that such standard, limitation,
prohibition, or regulation is not less stringent than any requirement
applicable to such source established under this part;
(2) Requiring the owner or operator of an affected source to obtain
permits, licenses, or approvals prior to initiating construction,
reconstruction, modification, or operation of such source; or
(3) Requiring emission reductions in excess of those specified in
subpart D of this part as a condition for granting the extension of
compliance authorized by section 112(i)(5) of the Act.
(b)(1) Section 112(l) of the Act directs the Administrator to
delegate to each State, when appropriate, the authority to implement and
enforce standards and other requirements pursuant to section 112 for
stationary sources located in that State. Because of the unique nature
of radioactive material, delegation of authority to implement and
enforce standards that control radionuclides may require separate
approval.
(2) Subpart E of this part establishes procedures consistent with
section 112(l) for the approval of State rules or programs to implement
and enforce applicable Federal rules promulgated under the authority of
section 112. Subpart E also establishes procedures for the review and
withdrawal of section 112 implementation and enforcement authorities
granted through a section 112(l) approval.
(c) All information required to be submitted to the EPA under this
part also shall be submitted to the appropriate State agency of any
State to which authority has been delegated under section 112(l) of the
Act, provided that each specific delegation may exempt sources from a
certain Federal or State reporting requirement. The Administrator may
permit all or some of the information to be submitted to the appropriate
State agency only, instead of to the EPA and the State agency.
Sec. 63.13 Addresses of State air pollution control agencies and EPA Regional Offices.

additional information considered available by the permitting authority.
Construct a major source means:
(1) To fabricate, erect, or install at any greenfield site a
stationary source or group of stationary sources which is located within
a contiguous area and under common control and which emits or has the
potential to emit 10 tons per year of any HAP's or 25 tons per year of
any combination of HAP, or
(2) To fabricate, erect, or install at any developed site a new
process or production unit which in and of itself emits or has the
potential to emit 10 tons per year of any HAP or 25 tons per year of any
combination of HAP, unless the process or production unit satisfies
criteria in paragraphs (2) (i) through (vi) of this definition.
(i) All HAP emitted by the process or production unit that would
otherwise be controlled under the requirements of this subpart will be
controlled by emission control equipment which was previously installed
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 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.
Control technology means measures, processes, methods, systems, or
techniques to limit the emission of hazardous air pollutants through

(5) Are a combination of paragraphs (1) through (4) of this
definition.
Effective date of section 112(g)(2)(B) in a State or local
jurisdiction means the effective date specified by the permitting
authority at the time the permitting authority adopts a program to
implement section 112(g) with respect to construction or reconstruction
or major sources of HAP, or June 29, 1998 whichever is earlier.
Electric utility steam generating unit means any fossil fuel fired
combustion unit of more than 25 megawatts that serves a generator that
produces electricity for sale. A unit that co-generates steam and
electricity and supplies more than one-third of its potential electric
output capacity and more than 25 megawatts electric output to any
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.
Notice of MACT Approval means a document issued by a permitting
authority containing all federally enforceable conditions necessary to
enforce the application and operation of MACT or other control
technologies such that the MACT emission limitation is met.
Permitting authority means the permitting authority as defined in

of the fixed capital cost that would be required to construct a
comparable process or production unit; and
(2) It is technically and economically feasible for the
reconstructed major source to meet the applicable maximum achievable
control technology emission limitation for new sources established under
this subpart.
Research and development activities means activities conducted at a
research or laboratory facility whose primary purpose is to conduct
research and development into new processes and products, where such
source is operated under the close supervision of technically trained
personnel and is not engaged in the manufacture of products for sale or
exchange for commercial profit, except in a de minimis manner.
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 Secs. 63.40 through
63.44, shall make any
[[Page 71]]
additions and revisions to its existing programs, procedures, and
criteria that the permitting authority deems necessary to properly
effectuate Secs. 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 Secs. 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 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 Secs. 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 Secs. 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
[[Page 72]]
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 (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
[[Page 73]]
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 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;
[[Page 74]]
(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.
(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)

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 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
[[Page 77]]
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]
Secs. 63.45-63.49 [Reserved]
Sec. 63.50 Applicability.
(a) General applicability. The requirements of Secs. 63.50 through
63.56 implement section 112(j) of the Clean Air Act (as amended in
1990). The requirements of Secs. 63.50 through 63.56 apply in each State
beginning on the effective date of an approved title V permit program in
such State. These requirements apply to the owner or operator of a major
source of hazardous air pollutants which includes one or more stationary
sources included in a source category or subcategory for which the
Administrator has failed to promulgate an emission standard under this
part by the section 112(j) deadline.
(b) Relationship to State and local requirements. Nothing in
Secs. 63.50 through 63.56 shall prevent a State or local regulatory
agency from imposing more stringent requirements than those contained in
these subsections.
(c) Retention of State permit program approval. In order to retain
State permit program approval, a State must, by the section 112(j)
deadline for a source category, obtain sufficient legal authority to
establish equivalent emission limitations, to incorporate those
requirements into a title V permit, and to incorporate and enforce other
requirements of section 112(j).

reconstruction of which is commenced before EPA proposed a standard,
applicable to the major source, under section 112 (d) or (h), or if no
proposal was published, then on or before the section 112(j) deadline.
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

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
(ii) The average emission limitation achieved by the best performing
five sources in the United States (for which the Administrator has or
could reasonably obtain emissions information) in the category or
subcategory, for a category or subcategory of stationary sources with
fewer than 30 sources;
(2) For new sources, the emission limitation achieved in practice by
the best controlled similar source.
New emission unit means an emission unit for which construction or
reconstruction is commenced after the section 112(j) deadline, or after
proposal of a relevant standard under section 112(d) or section 112(h)
of the Clean Air Act (as amended in 1990), whichever comes first, except
that, as provided by Sec. 63.52(f)(1), an emission unit, at a major
source, for which construction or reconstruction is commenced before the
date upon which the area source becomes a major source, shall not be
considered a new emission unit if, after the addition of such emission
unit, the source is still an area source.
New major source means a major source for which construction or
reconstruction is commenced after the section 112(j) deadline, or after
proposal of a relevant standard under section 112(d) or section 112(h)
of the Clean Air Act (as amended in 1990), whichever comes first.
Permitting authority means the permitting authority as defined in
part 70 of this chapter.
Section 112(j) deadline means the date 18 months after the date by
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

FR 26314, May 14, 1999]
Sec. 63.52 Approval process for new and existing emission units.
(a) Application. (1) Except as provided in Sec. 63.52(a)(3), if the
Administrator fails to promulgate an emission standard under this part
on or before an applicable section 112(j) deadline for a source category
or subcategory, the owner or operator of an existing major source that
includes one or more stationary sources in such category or subcategory,
shall submit an application for a title V permit or application for a
significant permit modification, whichever is applicable, by the section
112(j) deadline.
[[Page 80]]
(2) If the Administrator fails to promulgate an emission standard
under this part on or before an applicable section 112(j) deadline for a
source category or subcategory, the owner or operator of a new emission
unit in such source category or subcategory shall submit an application
for a title V permit or application for a significant permit
modification or administrative amendment, whichever is applicable, in
accordance with procedures established under title V.
(3)(i) The owner or operator of an existing major source that
already has a title V permit requiring compliance with a limit that
would meet the requirements of section 112(j) of the Act, shall submit
an application for an administrative permit amendment, by the section
112(j) deadline, in accordance with procedures established under title
V.
(ii) The owner or operator of a new emission unit that currently
complies with a federally enforceable alternative emission limitation,
or has a title V permit that already contains emission limitations
substantively meeting the requirements of section 112(j), shall submit
an application for an administrative permit amendment confirming
compliance with the requirements of section 112(j), in accordance with
procedures established under title V, and not later than the date 30
days after the date construction or reconstruction is commenced.
(4) In addition to meeting the requirements of Sec. 63.52(a)(2), the
owner or operator of a new emission unit may submit an application for a
Notice of MACT Approval before construction, pursuant to Sec. 63.54.
(b) Permit review. (1) Permit applications submitted under this
paragraph will be reviewed and approved or disapproved according to
procedures established under title V, and any other regulations approved
under title V in the jurisdiction in which the emission unit is located.
In the event that the permitting authority disapproves a permit
application submitted under this paragraph or determines that the
application is incomplete, the owner or operator shall revise and
resubmit the application to meet the objections of the permitting
authority not later than six months after first being notified that the
application was disapproved or is incomplete.
(2) If the owner or operator has submitted a timely and complete
application for a title V permit, significant permit modification, or
administrative amendment required by this paragraph, any failure to have
this permit will not be a violation of the requirements of this
paragraph, 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.
(c) Emission limitation. The permit or Notice of MACT Approval,
whichever is applicable, shall contain an equivalent emission limitation
(or limitations) for that 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 permit or Notice of MACT
Approval 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 shall 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 permit or Notice will contain an emission standard or
emission limitation to control the emissions of hazardous air
pollutants. The MACT emission limitation will be determined by the
permitting authority and will 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. Such
emission limitation will be established consistent with the principles
contained in Sec. 63.55.
(2) The permit or Notice will specify any notification, operation
and maintenance, performance testing, monitoring, reporting and
recordkeeping requirements. The permit or Notice will include the
following information:
(i) In addition to the MACT emission limitation required by
paragraph (c)(1) of this section, additional emission limits, production
limits, operational limits or other terms and conditions
[[Page 81]]
necessary to ensure federal 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, Sec. 63.52(e), and, at the discretion
of the permitting authority, to subpart A of this part;
(iii) A statement requiring the owner or operator to comply with all
requirements contained in subpart A of this part deemed by the
permitting authority to be applicable;
(iv) A compliance date(s) by which the owner or operator shall be in
compliance with the MACT emission limitation, and all other applicable
terms and conditions of the Notice.
(d)(1) Compliance date. The owner or operator of an existing major
source subject to the requirements of this paragraph shall comply with
the emission limitation(s) established in the source's title V permit.
In no case will such compliance date exceed 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), or unless otherwise specified in section
112(i), or in subpart D of this part.
(2) The owner or operator of a new emission unit subject to the
requirements of this paragraph shall comply with a new source MACT level
of control immediately upon issuance of the title V permit for the
emission unit.
(e) Enhanced monitoring. In accordance with section 114(a)(3) of the
Act, monitoring shall be capable of detecting deviations from each
applicable emission limitation or other standard with sufficient
reliability and timeliness to determine continuous compliance over the
applicable reporting period. Such monitoring data may be used as a basis
for enforcing emission limitations established under this subpart.
(f) Area sources that become major sources. (1) After the effective
date of this subpart, the owner or operator of a new or existing area
source that increases its emissions of, or its potential to emit,
hazardous air pollutants such that the source becomes a major source
that is subject to this subpart shall submit an application for a title
V permit or application for a significant permit modification, or
administrative amendment, whichever is applicable, by the date that such
source becomes a major source.
(i) If an existing area source becomes a major source by the
addition of an emission unit or as a result of reconstructing, that
added emission unit or reconstructed emission unit shall comply with all
requirements of this subpart that affect new emission units, including
the compliance date for new emission units established in Sec. 63.52(d).
(ii) If an area source, constructed after the section 112(j)
deadline, becomes a major source solely by virtue of a relaxation in any
federally enforceable emission limitation, established after the section
112(j) deadline, on the capacity of an emission unit or units to emit a
hazardous air pollutant, such as a restriction on hours of operation,
then that emission unit or units shall comply with all requirements of
this subpart that affect new emission units, on or before the date of
such relaxation.
(2) After the effective date of this subpart, if the Administrator
establishes a lesser quantity emission rate under section 112(a)(1) of
the Act that results in an area source becoming a major source, then the
owner or operator of such major source shall submit an application for a
title V permit or application for a significant permit modification, or
administrative amendment, whichever is applicable, on or before the date
6 months from the date that such source becomes a major source. If an
existing area source becomes a major source as a result of the
Administrator establishing a lesser quantity emission rate, then any
emission unit, at that source, for which construction or reconstruction
is commenced before the date upon which the source becomes major shall
not be considered a new emission unit.

(13) Except as provided in Sec. 63.55(a)(3), parameters to be
monitored and frequency of monitoring to demonstrate continuous
compliance with the MACT emission limitation over the applicable
reporting period.
(14) Any other information required by the permitting authority
including, at the discretion of the permitting authority, information
required pursuant to subpart A of this part.
Sec. 63.54 Preconstruction review procedures for new emission units.
(a) Review process for new emission units. (1) If the permitting
authority requires an owner or operator to obtain or revise a title V
permit before construction of the new emission unit, or when the owner
or operator chooses to obtain or revise a title V permit before
construction, the owner or operator shall follow the administrative
procedures established under title V before construction of the new
emission unit.
(2) If an owner or operator is not required to obtain or revise a
title V permit before construction of the new emission unit (and has not
elected to do so), but the new emission unit is covered by any
preconstruction or pre-operation review requirements established
pursuant to section 112(g) of the Act, then the owner or operator shall
comply with those requirements, in order to ensure that the requirements
of section 112(j) and section 112(g) are satisfied. If the new emission
unit 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 (h)
of this section, or an
[[Page 83]]
equivalent permit review process, before construction or operation of
the new emission unit.
(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.
(b) Optional administrative procedures for preconstruction or pre-
operation review for new emission units. The permitting authority may
provide for an enhanced review of section 112(j) MACT determinations
that provides for review procedures and compliance requirements
equivalent to those set forth in paragraphs (b) through (h) 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 will be
set forth in a Notice of MACT Approval (or the equivalent) as described
in Sec. 63.52(c).
(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(c). The form and content of the notice will 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
will 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
the region in which the new source would be located. The permitting
authority will provide EPA with a review period for the final notice of
at least 45 days, and will not issue a final Notice of MACT approval
unless EPA objections are satisfied.
(e) Effective date. The effective date for new sources under this
subsection shall be the date a Notice of MACT Approval is issued to the
owner or operator of a new emission unit.
(f) Compliance date. New emission units shall comply with case-by-
case MACT upon issuance of a title V permit for the emission unit.
(g) Compliance with MACT Determinations. An owner or operator of a
major source that is subject to a MACT determination shall comply with
notification, operation and maintenance, performance testing,
monitoring, reporting, and recordkeeping requirements established under
Sec. 63.52(e), under title V, and at the discretion of the permitting
authority, under subpart A of this part. The permitting authority will
provide the EPA with the opportunity to review compliance requirements
for
[[Page 84]]
consistency with requirements established pursuant to title V during the
review period under paragraph (d) of this section.
(h) 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.
Sec. 63.55 Maximum achievable control technology (MACT) determinations for emission units subject to case-by-case determination of equivalent emission
limitations.
(a) Requirements for emission units subject to case-by-case
determination of equivalent emission limitations. The owner or operator
of a major source submitting an application pursuant to Sec. 63.52 or
Sec. 63.54 shall include elements specified in Sec. 63.53, taking into
consideration the following requirements:
(1) When the Administrator has proposed a relevant emission standard
for the source category pursuant to section 112(d) or section 112(h) of
the Act, then the control technologies recommended by the owner or
operator under Sec. 63.53(b)(12), when applied to the emission points
recommended by the applicant for control, shall be capable of achieving
all emission limitations and requirements of the proposed standard
unless the application contains information adequate to support a
contention that:
(i) Different emissions limitations represent the maximum achievable
control technology emission limitations for the source category, or
(ii) Requirements different from those proposed by EPA will be
effective in ensuring that MACT emissions limitations are achieved.
(2) When the Administrator or the permitting authority has issued
guidance or distributed information establishing a MACT floor finding
for the source category or subcategory by the section 112(j) deadline,
then the recommended MACT emission limitations required by
Sec. 63.53(b)(11) must be at least as stringent as the MACT floor,
unless the application contains information adequately supporting an
amendment to such MACT floor.
(3)(i) When neither the Administrator nor the permitting authority
has issued guidance or distributed information establishing a MACT floor
finding and MACT determination for a source category or subcategory by
the section 112(j) deadline, then the owner or operator shall submit an
application for a permit or application for a Notice of MACT Approval,
whichever is applicable, containing the elements required by
Sec. 63.53(b) (1) through (9) and (14), by the section 112(j) deadline.
(ii) The owner or operator may recommend a control technology that
either achieves a level of control at least as stringent as the emission
control that is achieved in practice by the best controlled similar
source, or obtains at least the maximum reduction in emissions of
hazardous air pollutants that is achievable considering costs, non air
quality health and environmental impacts, and energy requirements.
(4) The owner or operator may 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 a hazardous air pollutant (HAP) or HAPs 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.
(b) Requirements for permitting authorities. The permitting
authority will determine whether the permit application or application
for a Notice of MACT Approval is approvable. If approvable, the
permitting authority will establish hazardous air pollutant emissions
limitations equivalent to the limitation that would apply if an emission
standard had been issued in a timely manner under subsection 112 (d) or
(h) of the Act. The permitting authority
[[Page 85]]
will establish these emissions limitations consistent with the following
requirements and principles:
(1) Emission limitations will be established for all emission units
within a source category or subcategory for which the section 112(j)
deadline has passed.
(2) Each emission limitation for an existing emission unit will
reflect the maximum degree of reduction in emissions of hazardous air
pollutants (including a prohibition on such emission, 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 emission units in the category or subcategory for which the section
112(j) deadline has passed. This limitation will not be less stringent
than the MACT floor, and will be based upon available information and
information generated by the permitting authority before or during the
application review process, including information provided in public
comments.
(3) Each emission limitation for a new emission unit will not be
less stringent than the emission limitation achieved in practice by the
best controlled similar source, and 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 will be
based at a minimum upon available information and information provided
in public comments.
(4) When the Administrator has proposed a relevant emissions
standard for the source category pursuant to section 112(d) or section
112(h) of the Act, then the equivalent emission limitation established
by the permitting authority shall ensure that all emission limitations
and requirements of the proposed standard are achieved, unless the
permitting authority determines based on additional information that:
(i) Different emissions limitations represent the maximum achievable
control technology emission limitations for the source category; or
(ii) Requirements different from those proposed by EPA will be
effective in ensuring that MACT emissions limitations are achieved.
(5) When the Administrator or the permitting authority has issued
guidance or collected information establishing a MACT floor finding for
the source category or subcategory, the equivalent emission limitation
for an emission unit must be at least as stringent as that MACT floor
finding unless, based on additional information, the permitting
authority determines that the additional information adequately supports
an amendment to the MACT floor. In that case, the equivalent emission
limitation must be at least as stringent as the amended MACT floor.
(6) The permitting authority will 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 a hazardous air pollutant (HAP) or HAPs 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.
(7) Nothing in this subpart will prevent a State or local permitting
authority from establishing an emission limitation more stringent than
required by Federal regulations.
(c) Reporting to National Data Base. The owner or operator shall
submit additional copies of its application for a permit, permit
modification, administrative amendment, or Notice of MACT Approval,
whichever is applicable, to the EPA by the section 112(j) deadline for
existing emission units, or by the date of the application for a permit
or
[[Page 86]]
Notice of MACT Approval for new emission units.
Sec. 63.56 Requirements for case-by-case determination of equivalent emission limitations after promulgation of a subsequent MACT standard.
(a) If the Administrator promulgates an emission standard that is
applicable to one or more emission units within a major source before
the date a permit application under this paragraph is approved, the
permit shall contain the promulgated standard rather than the emission
limitation determined under Sec. 63.52, 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 (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 shall revise the permit upon its next renewal to
reflect the promulgated standard. The permitting authority will
establish a compliance date in the revised permit that assures that the
owner or operator shall 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
permit, whichever is earlier.
(c) Notwithstanding the requirements of paragraph (a) or (b) of this
section, if the Administrator promulgates an emission standard that is
applicable to a source after the date a permit application 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 level of control required by the emission
limitation in the permit is at least as stringent as that required by
the promulgated standard.

Reductions of Hazardous Air Pollutants
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.

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
[[Page 89]]
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 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
[[Page 90]]
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.
(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
Mg=the total mass rate (e.g., kg/yr) of all
gaseous emissions
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
[[Page 91]]
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
[[Page 92]]
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 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), 401 M Street, SW., Washington, DC 20460
and the EPA Emission Standards Division (MD-13), Research Triangle Park,
NC 27711; attention both to the Early Reductions Officer. The commitment
shall contain:
(1) The name and address of the source;
(2) The name and telephone number of the source owner or operator or
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
[[Page 93]]
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 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), 401 M Street, SW., 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
[[Page 94]]
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 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:
[[Page 95]]
(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.
(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
[[Page 96]]
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 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 Secs. 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
Source: 58 FR 62283, Nov. 26, 1993, unless otherwise noted.
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 or
programs 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). 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 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.
Applicability criteria means the regulatory criteria used to define
all emission points within all affected sources subject to a specific
section 112 rule.
Approval means a determination by the Administrator that a State
rule or program meets the criteria of Sec. 63.91 and the additional
criteria of either
[[Page 97]]
Sec. 63.92, Sec. 63.93 or Sec. 63.94, where appropriate. For accidental
release prevention programs, the criteria of Sec. 63.95 must also be
met.
Compliance and enforcement measures means requirements within a rule
or program relating to compliance and enforcement, including but not
necessarily limited to monitoring, test methods and procedures,
recordkeeping, reporting, compliance certification, inspection, entry,
sampling or accidental release prevention oversight.
Level of control means the degree to which a rule or program
requires a source to limit emissions or to employ design, equipment,
work practice, operational, 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 or program would not lead to an increase in risk to human health or
the environment; and
(2) Each substance regulated under section 112(r).
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 a source regulated
under section 112(r).
Program means, for the purposes of an approval under Sec. 63.94, a
collection of State statutes, rules or other requirements which limits
or will limit the emissions of hazardous air pollutants from affected
sources.
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.
(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) 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) The authority to add or delete substances from the list of
substances established under section 112(r);
(iii) The authority to 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;
(iv) 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
(v) 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.
(d) Federally-enforceable requirements. All rules and requirements
approved under this subpart and all resulting part 70 operating permit
conditions are enforceable by the Administrator and citizens under the
Act.
(e) 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 40 CFR part 61, subpart I, T, or
W, 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
[[Page 98]]
content of the standard will be approved pursuant to Sec. 63.92,
Sec. 63.93, or Sec. 63.94.
[58 FR 62283, Nov. 26, 1993, as amended at 61 FR 36297, July 10, 1996]
Sec. 63.91 Criteria common to all approval options.
(a) Approval process. To obtain approval under this subpart of a
rule or program that is different from the Federal rule, the criteria of
this section and the criteria of either Sec. 63.92, Sec. 63.93 or
Sec. 63.94 must be met. For approval of State programs to implement and
enforce Federal section 112 rules as promulgated without changes (except
for accidental release programs), only the criteria of this section must
be met. This includes State requests for upfront approval of their
mechanism for taking delegation of future unchanged Federal section 112
standards and requirements as well as approval to implement and enforce
unchanged Federal section 112 standards and requirements on a rule-by
rule basis. For approval of State rules or programs to implement and
enforce the Federal accidental release prevention program as promulgated
without changes, the requirements of this section and section Sec. 63.95
must be met. In the case of accidental release prevention programs which
differ from the Federal accidental release prevention program, the
requirements of this section, Sec. 63.95, and either Sec. 63.92 or
Sec. 63.93 must be met. 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 of pollutants listed
pursuant to Section 112(b) of the Clean Air Act. For a State's initial
request for approval of any rule or program under this subpart, and
except as otherwise specified under Sec. 63.92, Sec. 63.93, or
Sec. 63.94 for a State's subsequent requests for approval, the approval
process will be the following:
(1) Upon receipt of a request for approval, the EPA will review the
request for approval and notify the State within 30 days of receipt
whether the request for approval is complete according to the criteria
in this subpart. If a request for approval is found to be incomplete,
the Administrator will so notify the State and will specify the
deficient elements of the State's request.
(2) Within 45 days after receipt of a complete request for approval,
the Administrator will seek public comment for a minimum of 30 days on
the State request for approval. The Administrator will require that
comments be submitted concurrently to the State.
(3) If, after review of public comments and any State responses to
comments submitted to the Administrator within 30 days of the close of
the public comment period, the Administrator finds that the criteria of
this section are met, the State rule or program will be approved by the
Administrator under this section, published in the Federal Register, and
incorporated directly or by reference, in the appropriate subpart of
part 63. Authorities approved under Sec. 63.95 will be incorporated
pursuant to requirements under section 112(r).
(4) Within 180 days of receiving a complete request for approval,
the Administrator will either approve or disapprove the State rule or

pursuant to requirements under section 112(r).
(3) If the Administrator finds that any of the requirements of this
section or Sec. 63.91 have not been met, the Administrator will
disapprove the State authorities.
(4) Authorities submitted for approval under this section shall
include either:
(i) State rules or other requirements enforceable under State law
that would substitute for a section 112 rule; or
(ii)(A) The specific permit terms and conditions for the source or
set of sources in the source category for which the State is requesting
approval under this section, including control requirements and
compliance and enforcement measures, that would substitute for the
permit terms and conditions imposed by the otherwise applicable section
112 rule for such source or set of sources.
(B) The Administrator will approve authorities specified under
paragraph (a)(4)(ii)(A) of this section only when the State submitting
the request already has an approved program under Sec. 63.94, the
Federal standard for the source category has been promulgated under
section 112(h), and the Administrator has not determined the work
practice, design, equipment or operational requirements submitted by the
State to be inadequate under the provisions of the Federal standard.
(5) Within 180 days of receiving a complete request for approval
under this section, the Administrator will either 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 authorities contain or demonstrate:
(1) Applicability criteria that are no less stringent than those in
the respective Federal rule;
(2) Levels of control 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 assures that each affected source is
in compliance no later than would be required by the otherwise
applicable Federal rule; and
(4) At a minimum, the approved State authorities must include the
following compliance and enforcement measures. (For authorities

rule or program and the State shall provide that information within 45
days of the Administrator's request:
(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.
[[Page 104]]
(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 resources 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 subpart 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 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.
[[Page 105]]
(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.

Subpart F--National Emission Standards for Organic Hazardous Air
Pollutants From the Synthetic Organic Chemical Manufacturing Industry
Source: 59 FR 19454, Apr. 22, 1994, unless otherwise noted.
Sec. 63.100 Applicability and designation of source.
(a) This subpart provides applicability provisions, definitions, and
other general provisions that are applicable to subparts G and H of this
part.
(b) Except as provided in paragraphs (b)(4) and (c) of this section,
the provisions of subparts F, G, and H of this part apply to chemical
manufacturing process units that meet all the criteria specified in
paragraphs (b)(1), (b)(2), and (b)(3) of this section:
(1) Manufacture as a primary product one or more of the chemicals
listed in paragraphs (b)(1)(i) or (b)(1)(ii) of this section.
(i) One or more of the chemicals listed in table 1 of this subpart;
or
(ii) One or more of the chemicals listed in paragraphs (b)(1)(ii)(A)
or (b)(1)(ii)(B) of this section:
(A) Tetrahydrobenzaldehyde (CAS Number 100-50-5); or
(B) Crotonaldehyde (CAS Number 123-73-9).
(2) Use as a reactant or manufacture as a product, or co-product,
one or more of the organic hazardous air pollutants listed in table 2 of
this subpart;
(3) Are located at a plant site that is a major source as defined in
section 112(a) of the Act.
(4) The owner or operator of a chemical manufacturing processing
unit is exempt from all requirements of subparts F, G, and H of this
part until not later than April 22, 1997 if the owner or operator
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
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 Secs. 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
Emergency Planning and Community Right-to-Know Act (EPCRA) section 313,
then such reported annual emissions may be used to satisfy the
requirements of Sec. 63.100(b)(4)(i)(B).
(C) The owner or operator shall sum the amount of annual HAP
emissions from all emission points on the plant site. If the total
emissions of any one HAP are less than 10 tons per year and the total
emissions of any combination of HAP are less than 25 tons per year, the
plant site qualifies for the exemption described in paragraph (b)(4) of
[[Page 113]]
this section, provided that emissions are kept below these thresholds.
(ii) If such a determination is based on limitations and conditions
that are federally enforceable (as defined in subpart A of this part),
the owner or operator is not subject to the provisions of paragraph
(b)(4) of this section.
(c) The owner or operator of a chemical manufacturing process unit
that meets the criteria specified in paragraphs (b)(1) and (b)(3) of
this section but does not use as a reactant or manufacture as a product
or co-product, any organic hazardous air pollutant listed in table 2 of
this subpart shall comply only with the requirements of Sec. 63.103(e)
of this subpart. To comply with this subpart, such chemical
manufacturing process units shall not be required to comply with the
provisions of subpart A of this part.
(d) The primary product of a chemical manufacturing process unit
shall be determined according to the procedures specified in paragraphs
(d)(1), (d)(2), (d)(3), and (d)(4) of this section.
(1) If a chemical manufacturing process unit produces more than one
intended chemical product, the product with the greatest annual design
capacity on a mass basis determines the primary product of the process.
(2) If a chemical manufacturing process unit has two or more
products that have the same maximum annual design capacity on a mass
basis and if one of those chemicals is listed in table 1 of this
subpart, then the listed chemical is considered the primary product and
the chemical manufacturing process unit is subject to this subpart. If
more than one of the products is listed in table 1 of this subpart, then
the owner or operator may designate as the primary product any of the
listed chemicals and the chemical manufacturing process unit is subject
to this subpart.
(3) For chemical manufacturing process units that are designed and
operated as flexible operation units producing one or more chemicals
listed in table 1 of this subpart, the primary product shall be
determined for existing sources based on the expected utilization for
the five years following April 22, 1994 and for new sources based on the
expected utilization for the first five years after initial start-up.
(i) If the predominant use of the flexible operation unit, as
described in paragraphs (d)(3)(i)(A) and (d)(3)(i)(B) of this section,
is to produce one or more chemicals listed in table 1 of this subpart,
then the flexible operation unit shall be subject to the provisions of

(A) If the flexible operation unit produces one product for the
greatest annual operating time, then that product shall represent the
primary product of the flexible operation unit.
(B) If the flexible operation unit produces multiple chemicals
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 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
operation units shall be reported as part of an operating permit
application or as otherwise specified by the permitting authority.

(B) For chemical manufacturing process units that produce one or
more of the chemicals listed in paragraph (b)(1)(ii) of this section 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
12-month period preceding May 12, 1998.
(iv) If there is a change in the material stored in the storage
vessel, the owner or operator shall reevaluate the applicability of this
subpart to the vessel.
(3) Where a storage vessel is located at a major source that
includes one or more chemical manufacturing process units which place
material into, or receive materials from the storage vessel, but the
storage vessel is located in a tank farm (including a marine tank farm),
the applicability of this subpart F and subpart G of this part shall be
determined according to the provisions 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
[[Page 116]]
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
subpart applies.
(1) Where a loading rack is dedicated to a chemical manufacturing
process unit, the loading rack shall be considered part of that specific
chemical manufacturing process unit.
(i) If the chemical manufacturing process unit is subject to this
subpart according to the criteria specified in paragraph (b) of 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 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 (f)(9) or
(f)(10) of this section.
(ii) If a loading arm or loading hose is shared among chemical
manufacturing process units, and one of the chemical manufacturing
process units provides the greatest amount of the material that is
loaded by the loading arm or loading hose, then the loading arm or
loading hose is part of that chemical manufacturing process unit.
(A) If the chemical manufacturing process unit is subject to this
subpart according to the criteria specified in paragraph (b) of this
section, then the loading arm or loading hose is part of the source to
which this subpart applies unless the loading arm or loading hose meets
the criteria specified in paragraphs (f)(9) or (f)(10) of this section.

part of the source to which this subpart applies.
(iii) If a loading arm or loading hose is shared among chemical
manufacturing process units so that there is no single predominant use
as described in paragraph (h)(2)(ii) of this section and at least one of
those chemical manufacturing process units is subject to this subpart,
then the loading arm or hose is part of the chemical manufacturing
process unit that is subject to this subpart. If more than one of the
chemical manufacturing process units is subject to this subpart, the
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

2000. For the convenience of the user, the superseded text is set forth
as follows:
Sec. 63.101 Definitions.
* * * * *
Equipment leak means emissions of organic hazardous air pollutants
from a pump, compressor, agitator, pressure relief device, sampling
connection system, open-ended valve or line, valve, surge control
vessel, bottoms receiver, or instrumentation system in organic hazardous
air pollutant service as defined in Sec. 63.161 of subpart H of this
part.
* * * * *
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 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. For purposes of this paragraph, the term ``excess emissions''
means emissions in excess of those that would have occurred if there
were no start-up, shutdown, or malfunction and the owner or operator
complied with the relevant provisions of this subpart F, subparts G and/
or H of this part. The measures to be taken shall be identified in the
applicable start-up, shutdown, and malfunction plan, and may include,
but are not limited to, air pollution control technologies, recovery
[[Page 130]]
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 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
[[Page 131]]
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 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
[[Page 132]]
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 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
[[Page 133]]
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 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.
[[Page 134]]
(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 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
[[Page 135]]
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 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
[[Page 136]]
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.
(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
purging of equipment in the process during temporary shutdowns for
inspections, maintenance, and repair (i.e., a maintenance-turnaround)
and during periods which are not shutdowns (i.e., routine maintenance).
The descriptions shall:
(1) Specify the process equipment or maintenance tasks that are
anticipated to create wastewater during maintenance activities.
(2) Specify the procedures that will be followed to properly manage
the wastewater and control organic HAP emissions to the atmosphere; and
(3) Specify the procedures to be followed when clearing materials
from process equipment.
(c) The owner or operator shall modify and update the information
required by paragraph (b) of this section as needed following each
maintenance procedure based on the actions taken and the wastewaters
generated in the preceding maintenance procedure.
(d) The owner or operator shall implement the procedures described
in paragraphs (b) and (c) of this section as part of the start-up,
shutdown, and malfunction plan required under Sec. 63.6(e)(3) of subpart
A of this part.
(e) The owner or operator shall maintain a record of the information
required by paragraphs (b) and (c) of this section as part of the start-
up, shutdown, and malfunction plan required under Sec. 63.6(e)(3) of
subpart A of this part.

Sec. 63.138 Process wastewater provisions--performance standards for treatment processes managing Group 1 wastewater streams and/or residuals removed from
Group 1 wastewater streams.
(a) General requirements. This section specifies the performance
standards for treating Group 1 wastewater streams. The owner or operator
shall comply with the requirements as specified in paragraphs (a)(1)
through (a)(6) of this section. Where multiple compliance options are
provided, the options may be used in combination for different
wastewater streams and/or for different compounds (e.g., Table 8 versus
Table 9 compounds) in the same wastewater streams, except where
otherwise provided in this section. Once a Group 1 wastewater stream or
residual removed from a Group 1 wastewater stream has been treated in
accordance with this subpart, it is no longer subject to the
requirements of this subpart.
(1) Existing source. If the wastewater stream, at an existing
source, is Group 1 for Table 9 compounds, comply with Sec. 63.138(b).
(2) New source. If the wastewater stream, at a new source, is Group
1 for Table 8 compounds, comply with Sec. 63.138(c). If the wastewater
stream, at a new source, is Group 1 for Table 9 compounds, comply with
Sec. 63.138(b). If the wastewater stream, at a new source, is Group 1
for Table 8 and Table 9 compounds, comply with both Sec. 63.138(b) and
Sec. 63.138(c).
Note to paragraph (a)(2): The requirements for Table 8 and/or
Table 9 compounds are similar and often identical.
(3) Biological treatment processes. Biological treatment processes
in compliance with this section may be either open or closed biological
treatment processes as defined in Sec. 63.111. An open biological
treatment process in compliance with this section need not be covered
and vented to a control device as required in Sec. 63.133 through
Sec. 63.137 of this subpart. An open or a closed biological treatment
process in compliance with this section and using Sec. 63.145(f) or
Sec. 63.145(g) of this subpart to demonstrate compliance is not subject
to the requirements of Sec. 63.133 through Sec. 63.137 of this subpart.
A closed biological treatment process in compliance with this section
and using Sec. 63.145(e) of this subpart to demonstrate compliance shall
comply with the requirements of Sec. 63.133 through Sec. 63.137 of this
subpart. Waste management units upstream of an open or closed biological
treatment process shall meet the requirements of Sec. 63.133 through
Sec. 63.137 of this subpart, as applicable.
(4) Performance tests and design evaluations. If design steam
stripper option (Sec. 63.138(d)) or Resource Conservation and Recovery
Act (RCRA) option (Sec. 63.138(h)) is selected to comply with this
section, neither a design evaluation nor a performance test is required.
For any other non-biological treatment process, and for closed
biological treatment processes as defined in Sec. 63.111 of this
subpart, the owner or operator shall conduct either a design evaluation
as specified in Sec. 63.138(j), or a performance test as specified in
Sec. 63.145, of
[[Page 217]]
this subpart. For each open biological treatment process as defined in
Sec. 63.111 of this subpart, the owner or operator shall conduct a
performance test as specified in Sec. 63.145 of this subpart.
Note to paragraph (a)(4): 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.
(5) Control device requirements. When gases are vented from the
treatment process, the owner or operator shall comply with the
applicable control device requirements specified in Sec. 63.139 and
Sec. 63.145 (i) and (j), and the applicable leak inspection provisions
specified in Sec. 63.148, of this subpart. This requirement does not
apply to any open biological treatment process that meets the mass
removal requirements. Vents from anaerobic biological treatment
processes may be routed through hard-piping to a fuel gas system.
(6) Residuals: general. When residuals result from treating Group 1
wastewater streams, the owner or operator shall comply with the
requirements for residuals specified in Sec. 63.138(k) of this subpart.
(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 or control device to comply with emissions
limitations, the owner or operator may use multiple treatment processes
or control devices, respectively. For combinations of treatment
processes where the wastewater stream is conveyed by hard-piping, the
owner or operator shall comply with either the requirements of paragraph
(a)(7)(i) or (a)(7)(ii) of this section. For combinations of treatment
processes where the wastewater stream is not conveyed by hard-piping,
the owner or operator shall comply with the requirements of paragraph
(a)(7)(ii) of this section. For combinations of control devices, the
owner or operator shall comply with the requirements of paragraph
(a)(7)(i) of this section.
(i)(A) For combinations of treatment processes, the wastewater
stream shall be conveyed by hard-piping between the treatment processes.
For combinations of control devices, the vented gas stream shall be
conveyed by hard-piping between the control devices.
(B) 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
this section.
(C) The owner or operator shall identify, and keep a record of, the
combination of treatment processes or of control devices, including
identification of the first and last treatment process or control
device. The owner or operator shall include this information as part of
the treatment process description reported in the Notification of
Compliance Status.
(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
this section.
(B) The owner or operator shall identify, and keep a record of, the
combination of treatment processes, including identification of the
first and last treatment process. The owner or operator shall include
this information as part of the treatment process description reported
in the Notification of Compliance Status.
(C) The owner or operator shall determine the mass removed or
destroyed by each treatment process. The performance test or design
evaluation shall determine compliance for the combination of treatment
processes by adding together the mass removed or destroyed by each
treatment process.

owner or operator shall demonstrate by the procedures in either
paragraph (j)(1) or (j)(2) of this section that each closed biological
treatment process used to comply with paragraphs (f) or (g) of this
section achieves the conditions specified for compliance. If an open
biological treatment unit is used to comply with paragraph (f) or (g) of
this section, the owner or operator shall comply with Sec. 63.145(f) or
Sec. 63.145(g), respectively, of this subpart. Some biological treatment

[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 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
[[Page 226]]
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 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.
[[Page 227]]
(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 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.
(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
[[Page 228]]
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
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
[[Page 229]]
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 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.
[62 FR 2762, Jan. 17, 1997]
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
[[Page 230]]
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.
(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. 63.145(a)(7)(i) or Sec. 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
[[Page 231]]
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
to the biological treatment process are the points at which the
wastewater enters the first treatment process and exits the last
treatment process in the series, respectively, except as provided in
paragraph (a)(9)(ii) of this section.
(B) The inlet to the biological treatment process shall be the point
at which the wastewater enters the biological treatment process or the
outlet from the series of treatment processes identified in paragraph
(a)(7)(i)(A) of this section, except as provided in paragraph (a)(9)(ii)

each treatment process in the series of treatment processes. The mass
flow rate removed or destroyed by each treatment process shall be added
together to determine whether compliance has been demonstrated using
Sec. 63.145 (c), (d), (e), (f), and (g), as applicable. If a biological
treatment process is one of the treatment processes in the series of

be the point at which the wastewater enters the biological treatment
process, or the inlet to the equalization tank if all the criteria of
paragraph (a)(9)(ii) of this section are met.
(8) When using a biological treatment process to comply with

determination with adjustment for concentration and flowrate changes
made according to Sec. 63.144(b)(6) and Sec. 63.144(c)(4) of this
subpart, respectively. All Table 8 and/or Table 9 compounds measured to
determine the RMR, except as provided by Sec. 63.145(a)(6), shall be
included in the RMR calculation.
(9) The owner or operator determining the inlet for purposes of
demonstrating compliance with Sec. 63.145 (e), (f), or (g) of this
subpart may elect to comply with paragraph (a)(9)(i) or (a)(9)(ii) of
this section.
(i) When wastewater is conveyed exclusively by hard-piping from the
point of determination to a treatment process that is either the only
treatment process or the first in a series of treatment processes (i.e.,
no treatment processes or other waste management units are used upstream
of this treatment process to store, handle, or convey the wastewater),
the inlet to the treatment process shall be at any location from the
point of determination to where the wastewater stream enters the
treatment process. When samples are taken upstream of the treatment
process and before wastewater streams have converged, the owner or
operator shall ensure that the mass flow rate of all Group 1 wastewater
streams is accounted for when using Sec. 63.138 (e) or (f) to comply and
that the mass flow rate of all Group 1 and Group 2 wastewater streams is
accounted for when using Sec. 63.138(g) to comply, except as provided in

(ii) The owner or operator may consider the inlet to the
equalization tank as the inlet to the biological treatment process if
all the criteria in paragraphs (a)(9)(ii)(A) through (a)(9)(ii)(C) of
this section are met. The outlet from the series of treatment processes
prior to the biological treatment process is the point at which the
wastewater exits the last treatment process in the series prior to the
equalization tank, if the equalization tank and biological treatment
process are part of a series of treatment processes. The owner or
operator shall ensure that the mass flow rate of all Group 1 wastewater
streams is accounted for when using Sec. 63.138 (e) or (f) to comply and

exclusively by hard-piping to the biological treatment process and no
treatment processes or other waste management units are used to store,
handle, or convey the wastewater between the equalization tank and the
biological treatment process.

factor listed in Table 34 of this subpart. Concentration measurements
based on methods other than Method 305 may be adjusted by multiplying
each concentration by the compound-specific Fm factor listed in table 34
of this subpart. (For wastewater streams that are Group 1 for both Table
8 and Table 9 compounds, compliance is demonstrated only if the sum of
