Consolidated Federal Air Rule (CAR): Synthetic Organic Chemical
Manufacturing Industry
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This action promulgates a consolidated Federal air rule for
the Synthetic Organic Chemical Manufacturing Industry (SOCMI). In this
final rule, we (EPA) consolidate major portions of several new source
performance standards (NSPS) and national emission standards for
hazardous air pollutants (NESHAP) applicable to storage vessels,
process vents, transfer operations, and equipment leaks within the
SOCMI. The final rule pulls together applicable Federal SOCMI rules
into one integrated set of rules in order to simplify, clarify, and
improve implementation of the existing rules with which source owners
or operators must comply. The consolidated rule is an optional
compliance alternative for SOCMI sources; sources may simply continue
to comply with existing applicable rules or choose to comply with the
final consolidated rule. The effects of this consolidation are to
improve understandability, reduce burden, clarify requirements, and
improve implementation and compliance. This document also announces the
effective date of information collection requirements in a subpart in
the Code of Federal Regulations relating to standards of performance
for volatile organic compound emissions from the synthetic organic
chemical manufacturing industry reactor processes which was originally
published in the Federal Register on August 31, 1993.
DATES: This final rule is effective December 14, 2000. The
incorporation by reference of certain publications in the rule is
approved by the Director of the Federal Register as of December 14,
2000. The information collection requirements in 40 CFR part 60,
subpart RRR, became effective November 8, 1993 when the Office of
Management and Budget approved them.
ADDRESSES: Docket number A-96-01 contains information we considered in
developing these standards and is available for public inspection
between 8:00 a.m. and 5:30 p.m., Monday through Friday except for
Federal holidays at EPA's Air and Radiation Docket and Information

I. Background Information
Over the past 25 years, EPA has issued a series of Federal air
regulations, many of which affect the same plant site. As a result,
many facilities are now subject to multiple Federal rules applying to
different emission points. Each rule has its own emission control
requirements as well as monitoring, recordkeeping, and reporting
requirements. Although these rules were developed for different
purposes under different statutory authorities and apply to different
pollutants, they may impose many duplicative or near duplicative
requirements on a plant site, thus complicating implementation of and
compliance with these rules.
On March 16, 1995, President Clinton and Vice President Gore
announced several initiatives aimed at reinventing environmental
regulation. One of those initiatives was to consolidate Federal air
rules so that all Federal air rules for any single industry would be
incorporated into a single rule. This rule would consist of ``* * * one
set of emission limitations, monitoring, and recordkeeping and
reporting requirements.''
We selected the Federal air rules applying to the SOCMI for a pilot
project to study the feasibility and practical implications of
consolidating and streamlining existing rules, and to establish a
workable process for consolidation that can then be applied to other
consolidation efforts in the future. We selected the SOCMI as the pilot
because of the large number of similar Federal air regulations that can
apply at a single location. The SOCMI is subject to NSPS and NESHAP
under the Act, as well as to Resource Conservation and Recovery Act
(RCRA) air standards. The rules for a given type of emission point
require application of controls with similar control efficiencies and
include similar design, equipment, or operating standards. However, the
standards differ in their applicability and in some of their control,
monitoring, recordkeeping, and reporting requirements. Additionally,
both the SOCMI and State air pollution control agencies have expressed
great interest in consolidation of applicable Federal air requirements
to the extent possible for easier incorporation into title V operating
permits.
For these reasons, we believe that consolidation of the
requirements of the various rules into one rule greatly benefits both
the industry and government enforcement agencies. We believe that such
consolidation improves compliance and enforceability and reduces
resource needs.
II. Summary of Comments and Changes Since Proposal
We received 16 comment letters on the proposed CAR. The most
significant changes made as a result of the comments regarded the SOCMI
CAR unit, the scope of the rule, and connector monitoring. We address
only the major comments and changes in this preamble. We also made a
number of editorial changes and clarifications to make the CAR easier
to read and understand. The summary of public comments and our
responses are contained in the ``Consolidated Federal Air Rule for
Synthetic Organic Chemical Manufacturing Industry: Background
Information for Promulgated Standards,'' EPA 453/R-99-006, May 2000,
Docket No. A-96-01.
A. How Has EPA Changed the Definition of the SOCMI CAR Unit?
We have eliminated the concept of a SOCMI CAR unit (SCU), as
proposed, from the final rule. Commenters noted points of confusion in
the assignment procedures and in the definition of the SCU. One
commenter was specifically concerned that the complexity of the
applicability procedures may prohibit implementation at the State and
local levels. Commenters made suggestions to improve the clarity of
these provisions including a suggestion that the CAR provide examples
showing how SCU boundaries are determined; a rephrasing of the SCU
definition; and a request that the CAR include a provision that would
allow groups of like equipment, subject to one of the referencing
subparts, to implement the CAR even though other portions of the SCU
continue to comply with the applicable referencing subpart.
Because this is a pilot program for the SOCMI, at proposal we
limited the equipment that could opt into the CAR to plant sites with
SOCMI process units. Therefore, the proposed definition of SCU
contained specifications for what constituted a SOCMI process unit. The
proposed CAR (63 FR 57753) specified that facilities opting into the
CAR must do so on a SCU basis because we thought this would reduce
potential complexity of implementing the CAR. During development of the
proposed CAR, State representatives expressed a desire to allow larger
portions of sources to opt in as opposed to a more
[[Page 78270]]
piecemeal approach, indicating that it would be easier for them to
enforce the rule. Industry representatives generally preferred to allow
any regulated source (a source or facility subject to a referencing
subpart) to opt into the CAR. We felt that opting into the CAR on an
SCU basis would provide a small enough collection of emission points
and equipment to provide operational flexibility to the facility, but a
large enough collection to avoid possible confusion and additional
burden for regulatory authorities.
After reviewing the comments regarding the SCU and assignment
procedures, we have concluded that eliminating the confusion and
complexity added by the assignment procedures outweighs the reduction
in burden and complexity to State inspectors by requiring facilities to
opt in on a SCU (large collection of equipment) basis. Keeping track of
which equipment is in or out of a SCU and which SCU is complying with
the CAR appears to be more burdensome than keeping track of which
emission point is complying with what rule.
Therefore, to simplify the applicability provisions of the CAR, we
are allowing, in the final CAR, any affected source subject to a
referencing subpart to use the CAR as a compliance option with two
exceptions described below. This means that a facility may choose to
opt in, for example, one subpart Kb tank or all equipment at the
facility that is subject to a referencing subpart. For both regulator
and industry personnel, this eliminates the assignment procedures that
determine what equipment constitutes a SCU. With this change, it is not
necessary to keep track of new regulated sources and whether they are
part of a SCU or not.
There are two situations where the regulated source in the CAR does
not match the affected source of the referencing subpart. In one
situation, the affected source for 40 CFR part 61, subpart V is an
individual piece of equipment like a pump or a valve. We determined
that allowing owners or operators to opt in to the CAR on an individual
piece of equipment would not be workable. Therefore, owners or
operators must opt in the group of affected equipment at a process
unit. This does not alter the applicability of subpart V to a facility;
it only affects the set of equipment that can comply with the CAR.
The second situation where the regulated source in the CAR does not
match the affected source of the referencing subpart is in the HON.
Under the HON, the affected source is the total of all applicable
emission points at the plant site that are subject to the HON. Thus, a
HON facility that contains more than one CMPU, would consist of only
one affected source, which would be the collection of all subject
CMPU's. However, under the CAR the regulated source is collection of
emission points within each CMPU (as proposed under the original
concept in the CAR of the SCU). Thus, a HON facility can choose to opt
into the CAR on a CMPU basis, and not the entire collection of CMPU's
that comprise the HON affected source.
Although we believe that in most cases facilities will opt in as
much equipment and as many emission points as possible, the States and
owners or operators have the opportunity to work together to determine
the basis on which facilities can opt in their equipment that will
provide the ``best fit'' for both regulators and industry.
B. Has EPA Changed the Scope of the CAR Since Proposal?
We have not changed the scope of the CAR since proposal except for
one minor change that affects polystyrene process vents. We received
comments on incorporating or allowing other rules in the CAR, including
the following requests: Consolidate all rules that may apply to a
facility that has a SOCMI process unit on site, use the CAR as a
compliance option for new regulations, and allow rules that reference
the referencing subparts to use the CAR as a compliance option. These
comments and our rationale for not changing the scope of the CAR are
discussed in the following sections.
1. Incorporating or Allowing Other Rules in the CAR
Comments: Several commenters supported expanding the scope of the
CAR so that it completely incorporates rules that may apply to
facilities that have a SOCMI process unit on site. Commenters
specifically mentioned the HON wastewater provisions (40 CFR part 63,
subpart G); the Benzene Waste NESHAP provisions (40 CFR part 61,
subpart FF); and the SOCMI wastewater NSPS (40 CFR part 60, subpart
YYY). Some commenters requested that sources subject to the Petroleum
Refinery NESHAP, 40 CFR part 63, subpart CC, be allowed to use the CAR
to comply with subpart CC. Two commenters also referred to the
following 40 CFR part 63 subparts as rules that should allow the CAR as
a compliance option: I, U, W, DD, TT, OO, UU, WW, and JJJ. One
commenter requested consolidation of several other provisions affecting
SOCMI including the Hazardous Organic NESHAP (HON) Group 2 transfer
racks and storage vessels; emission points not requiring control under
the non-HON referencing subparts; marine loading under 40 CFR part 61,
subpart BB; and equipment leak provisions under subpart BB of both 40
CFR parts 264 and 265. One commenter encouraged us to define CAR
requirements as acceptable for requirements in non-consolidated rules
that are likely to overlap with the CAR at SOCMI sites.
Commenters argued that without including additional regulations in
the consolidation, issues of overlapping requirements remain, and the
CAR cannot achieve its goals. One commenter alleged that sources, in
most cases, have no incentive to use the CAR and concluded that the CAR
must consolidate several additional rules in order to provide this
incentive.
Response: It is true that the CAR does not consolidate all rules
applicable to the SOCMI or to sources with SOCMI processes on site. We
considered other rules in this consolidation. As stated in the preamble
to the proposed rule (63 FR 57750), because the rule was meant to be a
pilot project for the SOCMI, we limited the scope to the Federal Clean
Air Act rules that apply to SOCMI. We thought that these rules would
provide benefit to affected sources, yet the scope would be defined
well enough to ensure a reasonable chance of success. Some SOCMI rules
that we considered for consolidation were subject to litigation, which
could have led to substantial changes, when the CAR process started,
and others are currently in litigation. It was therefore not
appropriate to consolidate these rules into the CAR since they would
likely be changing. Our intention was to keep the rule development
process manageable in order to develop a practical CAR in a reasonable
amount of time. The details, approach, and regulatory text for
including additional rules in the CAR have not been investigated. To
include additional rules in the consolidation effort at this point
would require substantial time, resources, and a supplemental proposal.
We consider our efforts better spent finalizing this rule.
We do not agree that sources have no incentive to use the CAR. We
maintain that there can be significant burden reduction with the rules
that are currently consolidated, and that the burden reduction will
persuade sources to use the CAR.
2. CAR for New Regulations
Comments: Four commenters requested that we consider using the CAR
as a compliance option for new regulations. Two commenters
[[Page 78271]]
specifically mentioned the Miscellaneous Organic NESHAP, one commenter
mentioned the Generic MACT, and one commenter mentioned the Ethylene
MACT. One commenter recommended that any new regulations applicable to
the SOCMI that may be promulgated should be incorporated into the CAR
for use by affected sources that have opted to use the CAR. The
commenter stated that in this case, additional incorporated rules would
follow part 70 on opting new rules into a title V permit as they are
promulgated.
Response: We may consider using the CAR in future rulemakings.
Because of the timing of the Generic MACT's promulgation (64 FR 34854;
June 29, 1999), it was not possible to consolidate that rule into the
CAR. However, the Generic MACT employs similar structure, concept, and
provisions to the CAR.
3. Referencing Subparts Using the CAR
Comments: Several commenters requested that rules that refer to
referencing subparts should be allowed to use the CAR as a compliance
option. Commenters specifically mentioned 40 CFR part 63, subpart I,
the polymers and resins MACT standards, and 40 CFR part 60, subpart
DDD, equipment leak provisions. Two commenters requested any MACT
standard that points to the HON be allowed the option to comply with
the CAR.
Response: We have not expanded the scope of the final rule to
include other regulations that refer to referencing subparts. Expanding
the scope of the CAR to other rules at this point would entail
additional proposals. The details, approach, and ramifications of
allowing the CAR for these other rules have not been investigated. Many
of the rules that point to the CAR's referencing subparts for
requirements generally have complex references, with conditions and
exceptions to the referencing subparts. To allow these rules to comply
with the CAR would require us to study the conditions and exceptions
and possibly develop detailed references for compliance with the CAR.
We are finalizing this rule so that the burden reductions associated
with it can be used as soon as possible, and we may consider additional
provisions in later rulemakings.
4. Polystyrene Process Vents
Comment: One commenter noted that the proposed language in
Sec. 60.560(j) and (k) would not allow polystyrene process vents
subject to 40 CFR part 60, subpart DDD, to use the CAR. These process
vents have the same requirements as the polypropylene and polyethylene
process vents subject to subpart DDD that could opt into the CAR under
the proposed rule.
Response: We agree that the polystyrene process vents subject to
subpart DDD that choose the control device or flare compliance option
should be allowed to opt into the CAR. We have edited the final rule to
allow this option.
C. How Has EPA Changed the Connector Monitoring Requirements?
We have provided a sensory inspection alternative to instrument
monitoring for sources subject only to 40 CFR part 60, subpart VV and
40 CFR part 61, subpart V, to eliminate a disincentive to use the CAR.
Comments: Several commenters noted that the proposed CAR imposed a
significant increase in equipment leak monitoring burden for connectors
in gas/vapor or light liquid service if the owner or operator decided
to opt into the CAR for compliance. Specifically, these connectors
subject to 40 CFR part 60, subpart VV, and 40 CFR part 61, subpart V,
would have been subject to periodic instrument monitoring under the
CAR. Under the referencing subparts, however, instrument monitoring was
only required if sensory indications of a leak were detected. In other
words, if plant personnel see, hear, or smell a potential leak, then
they would investigate the potential leak by performing instrument
monitoring.
Instrument monitoring, the commenters noted, is a substantial
burden increase over sensory inspection. The commenters felt that this
created a financial disincentive to use the CAR for some owners or
operators. The commenters reasoned that if having to perform routine,
periodic instrument monitoring of connectors costs more than is saved
by complying with the CAR at the rest of the facility, then the owner
or operator would likely decide not to use the CAR.
The commenters also noted that removing the requirement for
instrument monitoring still has the potential to achieve an overall
increase in environmental benefit. By maintaining the status quo with
regard to performing sensory inspection for connectors, many subparts V
and VV facilities may opt into the CAR. Once in the CAR, they must
comply with the CAR's lower leak definitions for valves (500 parts per
million (ppm)) and pumps (1,000 ppm for pumps in general service)
instead of the referencing subparts' leak definition (10,000 ppm) for
this equipment. The lower leak definitions would push the facilities
towards better performance, potentially increasing the benefit to the
environment.
Response: We agree that initiating instrument monitoring for
connectors at a facility currently performing only sensory monitoring
presents a significant and unanticipated financial disincentive to
using the CAR. Because we believe that having more facilities using the
CAR will result in reduced burden for both industry and regulators, we
have provided a sensory monitoring option for sources subject only to
subparts V and VV to eliminate this disincentive.
We have modified the CAR so that it contains an exemption from the
instrument monitoring protocol for connectors referenced from subparts
V and VV. It should be noted that the owner or operator may choose to
perform instrument monitoring for these connectors if, for example, the
owner or operator wanted to have one set of protocols for all the
connectors at a facility and some of them were referenced to the CAR
from the HON. Instrument monitoring would be required for the
connectors referenced from the HON, and it may be simpler to instrument
monitor all of the connectors rather than single out some connectors
for instrument monitoring and others for sensory inspection.
No degradation of environmental protection results from the CAR
requiring sensory monitoring for connectors referenced from subparts V
and VV because that is what those two referencing subparts currently
require. In fact, as commenters noted, because the CAR consolidates on
lower leak definitions for other equipment, environmental protection
will potentially be strengthened because subparts V and VV have a
10,000 ppm leak definition.
D. What Changes Were Made to the Process of Implementing the CAR?
We clarified the provisions for setting the implementation schedule
to specify that the schedule must be set by mutual agreement with the
Administrator. This language was also revised to be consistent with the
CAR most likely being a minor permit modification to a title V permit.
In the proposed CAR, the implementation schedule was to be established
in a title V permit. It was meant to require that the regulated source
propose the implementation schedule in a title V amendment. The final
schedule as approved by the permitting authority would be established
in the title V permit. In other words, the permitting authority would
signal approval by including the schedule in the title V permit.
However,
[[Page 78272]]
since the title V amendment is a minor permit modification, there is no
real opportunity for the permitting authority's approval. Therefore,
the language associated with the implementation schedule was modified
to establish the schedule by mutual agreement between the source and
the permitting authority outside the title V process.
III. Other Changes Since Proposal
In addition to those changes discussed in section II of this
preamble, we made numerous other, less significant, changes, including
editorial changes and corrections to make the rule more clear. Most of
these changes were made in response to comment and are discussed in
detail in the BID (see the ADDRESSES section of this preamble).
IV. Has EPA Changed Its Approach for Delegating the CAR to State
Authorities?
No. Our approach is outlined here and clarification is provided
regarding States that do not have delegated authority of the underlying
rules but have an approved title V program.
At proposal, we specifically requested comment on this streamlined
approach to State delegation. Commenters who commented on delegation
were unanimous in support of our approach. They agreed with our
rationale and echoed our belief that the approach we outlined will
facilitate and expedite delegation and implementation of the CAR.
To avoid impeding the adoption of the CAR, we specified a
streamlined approach to implement the CAR using State authorities who
have been delegated authority for the referencing subparts. Our
approach is based on two steps. First, we intend to recognize the CAR
as an alternative compliance approach to the referencing subparts.
Second, we intend to waive the need for formal delegation of the CAR
where the State is already delegated authority to implement the
underlying NSPS or NESHAP. The details and implications of both of
these steps are discussed in detail in the proposal preamble (63 FR
57784; October 28, 1998).
One commenter supported an approach that would provide for
implementation of the CAR in States with an approved title V program,
regardless of whether the State has received formal delegation of the
underlying rules. We agree with the commenter that delegation of the
CAR could also occur when States have an approved title V program. We
recognize that fewer States have accepted delegation of the part 63
rules than the parts 60 and 61 rules. By incorporating the part 63
rules into the title V permit as applicable requirements, the terms and
conditions of the part 63 rules become enforceable by the permitting
authority through the permit, as if the part 63 rules themselves were
delegated. We agree that the CAR could be delegated to permitting
authorities with approved title V programs in place; however, there are
advantages to obtaining formal delegation of the CAR by the permitting
authority. Delegation should be conditioned to ensure the CAR is
substantively incorporated unchanged into the permit.
As stated above, there are advantages to accepting formal
delegation of the CAR. Permitting authorities that accept formal
delegation of the CAR through accepting delegation of the referencing
subparts, i.e., the HON (or accept formal delegation of any section 112
requirement), are the clear enforcement authorities. In other words, if
the permitting authority does not accept formal delegation of the
referencing subparts, then the EPA Regional Office remains the
enforcement authority, and sources must submit duplicate reports to
both the EPA Regional Office and the permitting authority.
Additionally, if the permitting authority accepts formal delegation of
the referencing subparts, then the permitting authority can make the
discretionary decisions regarding the general provisions authorities.
For example, if a source wants to change some facet of its monitoring
program, then, in some cases, a permitting authority that has accepted
delegation of the CAR will be able to approve this change. See the 40
CFR part 63, subpart E preamble (64 FR 1879; January 12, 1999) for more
information.
V. Has EPA Changed Its Approach for Incorporating CAR Requirements
Into the Title V Permit?
No. At proposal, we specifically requested comment on our
interpretation of using the minor permit modification mechanism to
implement the CAR at title V sources. Commenters agreed and expressed
support for our approach. The use of the CAR is subject to mutual
agreement with the Administrator, and the title V permit modification
is the appropriate mechanism.
The proposal preamble discussed the incorporation of the CAR
requirements into the title V permit in detail (63 FR 57786; October
28, 1998). At proposal, we reasoned that of the three mechanisms
through which a permit can be modified (administrative amendments,
minor permit modification, or significant modifications), a minor
permit modification is the correct mechanism to use to incorporate the
CAR in most cases. Because the source does not have significant
discretion in establishing the specific requirements, adopting the CAR
qualifies as a minor permit modification. In cases where the CAR allows
significant discretion on the part of the source in determining
monitoring, recordkeeping or reporting requirements, and these are
being established for the first time through the permit revision
process, we would consider this change to be a significant modification
to the permit. An example of this type of provision is under
Sec. 65.162(e) of 40 CFR part 65, subpart G, which applies to sources
who are directed under Sec. 65.154(c)(2) or Sec. 65.155(c)(1) to set
unique monitoring parameters.

[email protected], or by calling (202) 260-2740. A copy may also be
downloaded from the internet at http://www.epa.gov/icr. The information
requirements are not enforceable until OMB approves them.
Information is required to ensure compliance with the provisions of
the rules. The information collected pursuant to the CAR will be used
by Agency enforcement personnel to: (1) identify sources subject to the
standards, (2) identify the control methodology being applied, and (3)
ensure that the emission control devices are being properly operated
and maintained on a continuous basis.
In addition, records and reports are necessary to enable EPA to
identify plants that may not be in compliance with the standards. Based
on reported information, EPA can decide which plants should be
inspected and what records or processes should be inspected at the
plants. The records that plants maintain would indicate to EPA whether
plant personnel are operating and maintaining control equipment
properly.
[[Page 78273]]
These recordkeeping and reporting requirements are specifically
authorized by section 114 of the Clean Air Act (42 U.S.C. 7414). All
information submitted to the EPA for which a claim of confidentiality
is made will be safeguarded according to EPA policies in 40 CFR part 2,
subpart B, ``Confidentiality of Business Information.''
The rules require that facility owners or operators retain records
for a period of at least 5 years for title V sources, which exceeds the
3-year retention period contained in the guidelines in 5 CFR 1320.6.
The 5-year retention period is consistent with the general provisions
of 40 CFR part 63, and with the 5-year record retention requirement in
the operating permit program under title V of the Act.
Reports are required on a semi-annual basis and as required, such
as notification of performance testing. Information to be reported
consists of emission data and other information that are not of a
sensitive nature. If the relevant information were collected less
frequently, the EPA would not be reasonably assured that a source is in
compliance with the rules. In addition, the EPA's authority to take
administrative action would be reduced significantly. No sensitive
personal or proprietary information are being collected.
The burden estimate is an estimate of the recordkeeping and
reporting burden that will be incurred by a representative respondent
choosing to comply with the CAR. The estimated annual average hour
burden for all respondents is about 427,046 hours, or about 5,338 hours
per respondent. The estimated annual average cost of this burden is
about $23,051,000 for all of the estimated 80 projected respondents. An
additional cost for operation and maintenance of monitoring systems and
computers is about $32,333,600, for a total cost of about $702,708 per
respondent. The estimated annual average hour burden for the Federal
government is about 6,600 hours, with an associated cost of about
$263,000. These estimates do not include the burden reduction achieved
from not having to comply with the referencing subparts. The net burden
reduction to the industry is estimated to be about 464,000 hours per
year.
Burden means the total time, effort, or financial resources
expended by persons to generate, maintain, retain, or disclose or
provide information to or for a Federal agency. This includes the time
needed to review instructions; develop, acquire, install, and utilize
technology and systems for the purposes of collecting, validating, and
verifying information, processing and maintaining information, and
disclosing and providing information; adjust the existing ways to
comply with any previously applicable instructions and requirements;
train personnel to be able to respond to a collection of information;
search data sources; complete and review the collection of information;
and transmit or otherwise disclose the information.
An agency may not conduct or sponsor, and a person is not required
to respond to a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
B. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), the EPA
must determine whether a regulatory action is ``significant'' and
therefore subject to OMB review and the requirements of the Executive
Order. The Order defines ``significant regulatory action'' as one that
is likely to result in a rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or tribal governments or
communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs or the rights and obligations of recipients
thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
Pursuant to the terms of Executive Order 12866, OMB has notified
EPA that it considers this a ``significant regulatory action'' within
the meaning of the Executive Order. The EPA has submitted this action
to OMB for review. Changes made in response to OMB suggestions or
recommendations will be documented in the public record.
C. Executive Order 13132: Federalism
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.'' Under
Executive Order 13132, EPA may not issue a regulation that has
federalism implications, that imposes substantial direct compliance
costs, and that is not required by statute, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by State and local governments, or EPA consults with
State and local officials early in the process of developing the
proposed regulation. The EPA also may not issue a regulation that has
federalism implications and that preempts State law unless the Agency
consults with State and local officials early in the process of
developing the proposed regulation.
If EPA complies by consulting, Executive Order 13132 requires EPA
to provide to OMB, in a separately identified section of the preamble
to the rule, a federalism summary impact statement (FSIS). The FSIS
must include a description of the extent of EPA's prior consultation
with State and local officials, a summary of the nature of their
concerns and the agency's position supporting the need to issue the
regulation, and a statement of the extent to which the concerns of
State and local officials have been met. Also, when EPA transmits a
draft final rule with federalism implications to OMB for review
pursuant to Executive Order 12866, EPA must include a certification
from the agency's Federalism Official stating that EPA has met the
requirements of Executive Order 13132 in a meaningful and timely
manner.
This final rule will not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132.
This rule consolidates requirements for existing rules, and will result
in no net increase of recordkeeping and reporting to State agencies.
Thus, the requirements of section 6 of the Executive Order do not apply
to this rule. Although section 6 of Executive Order 13132 does not
apply to this rule, EPA did consult with State and local officials in
developing this rule.
[[Page 78274]]
D. Executive Order 13084: Consultation and Coordination With Indian
Tribal Governments
Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or EPA consults with those
governments. If EPA complies by consulting, Executive Order 13084
requires EPA to provide to the Office of Management and Budget, in a
separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, Executive Order 13084 requires EPA to develop
an effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.''
Today's rule does not significantly or uniquely affect the
communities of Indian tribal governments. Accordingly, the requirements
of section 3(b) of Executive Order 13084 do not apply to this rule.
E. Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and tribal
governments and the private sector. Under section 202 of the UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures to State, local, and tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any
1 year. Before promulgating an EPA rule for which a written statement
is needed, section 205 of the UMRA generally requires EPA to identify
and consider a reasonable number of regulatory alternatives and adopt
the least costly, most cost-effective or least burdensome alternative
that achieves the objectives of the rule. The provisions of section 205
do not apply when they are inconsistent with applicable law. Moreover,
section 205 allows EPA to adopt an alternative other than the least
costly, most cost-effective or least burdensome alternative if the
Administrator publishes with the final rule an explanation why that
alternative was not adopted. Before EPA establishes any regulatory
requirements that may significantly or uniquely affect small
governments, including tribal governments, it must have developed under
section 203 of the UMRA a small government agency plan. The plan must
provide for notifying potentially affected small governments, enabling
officials of affected small governments to have meaningful and timely
input in the development of EPA regulatory proposals with significant
Federal intergovernmental mandates, and informing, educating, and
advising small governments on compliance with the regulatory
requirements.
The EPA has determined that these rules do not contain a Federal
mandate that may result in expenditures of $100 million or more for
State, local, and tribal governments, in the aggregate or the private
sector in any 1 year. Thus, today's rules are not subject to the
requirements of sections 202 and 205 of the UMRA.
The EPA has determined that these rules contain no regulatory
requirements that might significantly or uniquely affect small
governments. No small government entities have been identified that
have involvement with these source categories and, as such, are not
covered by the regulatory requirements of the proposed regulations.
F. Regulatory Flexibility
The Regulatory Flexibility Act, as amended by the Small Business
Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et
seq., generally requires an agency to prepare a regulatory flexibility
analysis of any rule subject to notice and comment rulemaking
requirements unless the agency determines that the rule will not have a
significant economic impact on a substantial number of small entities.
Small entities include small businesses, small organizations, and small
governmental jurisdictions.
After considering the economic impacts of today's final rule on
small entities, EPA has determined that this action will not have a
significant economic impact on a substantial number of small entities
and therefore a regulatory flexibility analysis was not necessary. This
final rule is an optional compliance method and does not introduce any
new requirements. Sources, including small entities, may choose to
comply with the final rule if they determine that it would be
beneficial to do so. We have therefore concluded that today's final
rule will relieve regulatory burden for all small entities.
G. National Technology Transfer and Advancement Act
As stated in the proposed rule, section 12(d) of the National
Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law
104-113, section 12(d) (15 U.S.C. 272 note), directs the EPA to use
voluntary consensus standards in its regulatory activities unless to do
so would be inconsistent with applicable law or otherwise impractical.
Voluntary consensus standards are technical standards (e.g., materials
specifications, test methods, sampling procedures, business practices,
etc.) that are developed or adopted by voluntary consensus standard
bodies. The purpose of the NTTAA is to reduce the costs to the private
and public sectors by requiring Federal agencies to use existing
technical standards used in commerce or industry. The NTTAA directs EPA
to provide Congress, through OMB, explanations when the Agency decides
not to use available and applicable voluntary consensus standards.
The technical standards promulgated with this final rule are
standards that have been proposed and promulgated under other
rulemakings for similar source control applicability and compliance
determinations. Since today's final rule does not involve the
establishment or modification of technical standards, the requirements
of the NTTAA do not apply.
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any
rule that: (1) is determined to be ``economically significant'' as
defined under Executive Order 12866, and (2) concerns an environmental
health or safety risk that EPA has reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, the EPA must evaluate the environmental health or safety
effects of the planned rule on children, and explain why the planned
regulation is preferable to other potentially effective and reasonably
feasible alternatives considered by the Agency.
The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that are based on health or safety risks, such that
the analysis required under section 5-501 of the Executive Order has
the potential to
[[Page 78275]]
influence the regulation. This final rule is not subject to Executive
Order 13045 because it does not involve decisions on environmental
health risks or safety risks that may disproportionately affect
children.
I. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801, et seq., as added by
the SBREFA of 1996, generally provides that before a rule may take
effect, the agency adopting the rule must submit a rule report, which
includes a copy of the rule, to each House of the Congress and to the
Comptroller General of the United States. The EPA submitted a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this rule in the Federal
Register. A major rule cannot take effect until 60 days after it is
published in the Federal Register. This rule is not a ``major rule'' as
defined by 5 U.S.C. 804(2).

7. Section 60.481 is amended by revising the definition of ``Closed
vent system'' and adding in alphabetical order the definitions of
``Duct work,'' ``Fuel gas,'' ``Fuel gas system,'' ``Hard-piping,'' and
``Sampling connection system,'' to read as follows:
Sec. 60.481 Definitions.
* * * * *
Closed vent system means a system that is not open to the
atmosphere and that is composed of hard-piping, ductwork, connections,
and, if necessary, flow-inducing devices that transport gas or vapor
from a piece or pieces of equipment to a control device or back to a
process.
* * * * *
Duct work means a conveyance system such as those commonly used for
heating and ventilation systems. It is often made of sheet metal and
often has sections connected by screws or crimping. Hard-piping is not
ductwork.
* * * * *
Fuel gas means gases that are combusted to derive useful work or
heat.
Fuel gas system means the offsite and onsite piping and flow and
pressure control system that gathers gaseous stream(s) generated by
onsite operations, may blend them with other sources of gas, and
transports the gaseous stream for use as fuel gas in combustion devices
or in-process combustion equipment, such as furnaces and gas turbines,
either singly or in combination.
Hard-piping means pipe or tubing that is manufactured and properly
installed using good engineering judgement and standards such as ASME
B31.3, Process Piping (available from the American Society of
Mechanical Engineers, PO Box 2900, Fairfield, NJ 07007-2900).
* * * * *
Sampling connection system means an assembly of equipment within a
process unit used during periods of representative operation to take
samples of the process fluid. Equipment used to take nonroutine grab
samples is not considered a sampling connection system.
* * * * *
8. Section 60.482-1 is amended by revising paragraph (a) to read as
follows:
Sec. 60.482-1 Standards: General.
(a) Each owner or operator subject to the provisions of this
subpart shall demonstrate compliance with the requirements of
Secs. 60.482-1 through 60.482-10 or Sec. 60.480(e) for all equipment
within 180 days of initial startup.
* * * * *
9. Section 60.482-2 is amended by:
a. Revising paragraph (d)(1)(ii);
b. Revising paragraph (f);
c. Adding paragraph (g); and
d. Adding paragraph (h).
The revisions and additions read as follows:
Sec. 60.482-2 Standards: Pumps in light liquid service.
* * * * *
(d) * * *
(1) * * *
(ii) Equipment with a barrier fluid degassing reservoir that is
routed to a process or fuel gas system or connected by a closed vent
system to a control device that complies with the requirements of
Sec. 60.482-10; or
* * * * *
(f) If any pump is equipped with a closed vent system capable of
capturing and transporting any leakage from the seal or seals to a
process or to a fuel gas system or to a control device that complies
with the requirements of Sec. 60.482-10, it is exempt from paragraphs
(a) through (e) of this section.
(g) Any pump that is designated, as described in Sec. 60.486(f)(1),
as an unsafe-to-monitor pump is exempt from the monitoring and
inspection requirements of paragraphs (a) and (d)(4) through (6) of
this section if:
(1) The owner or operator of the pump demonstrates that the pump is
unsafe-to-monitor because monitoring personnel would be exposed to an
immediate danger as a consequence of complying with paragraph (a) of
this section; and
(2) The owner or operator of the pump has a written plan that
requires
[[Page 78277]]
monitoring of the pump as frequently as practicable during safe-to-
monitor times but not more frequently than the periodic monitoring
schedule otherwise applicable, and repair of the equipment according to
the procedures in paragraph (c) of this section if a leak is detected.
(h) Any pump that is located within the boundary of an unmanned
plant site is exempt from the weekly visual inspection requirement of
paragraphs (a)(2) and (d)(4) of this section, and the daily
requirements of paragraph (d)(5) of this section, provided that each
pump is visually inspected as often as practicable and at least
monthly.
10. Section 60.482-3 is amended by revising paragraphs (b)(2) and
(h) to read as follows:
Sec. 60.482-3 Standards: Compressors.

system to a control device that complies with the requirements of
Sec. 60.482-10; or
* * * * *
(h) A compressor is exempt from the requirements of paragraphs (a)
and (b) of this section, if it is equipped with a closed vent system to
capture and transport leakage from the compressor drive shaft back to a
process or fuel gas system or to a control device that complies with
the requirements of Sec. 60.482-10, except as provided in paragraph (i)
of this section.
* * * * *
11. Section 60.482-4 is amended by revising paragraph (c), and
adding paragraph (d) to read as follows:
Sec. 60.482-4 Standards: Pressure relief devices in gas/vapor service.
* * * * *
(c) Any pressure relief device that is routed to a process or fuel
gas system or equipped with a closed vent system capable of capturing
and transporting leakage through the pressure relief device to a

Subpart A--General Provisions
Sec. 65.1 Applicability.
(a) The provisions of this subpart apply to owners or operators
expressly referenced to this part from a subpart of 40 CFR part 60, 61,
or 63 for which the owner or operator has chosen to comply with the
provisions of this part as an alternative to the provisions in the
referencing subpart as specified in paragraph (b) of this section.
(b) Owners or operators may choose to comply with this part for any
regulated source subject to a referencing subpart.
(c) Compliance with this part instead of the referencing subparts
does not alter the applicability of the referencing subparts. This part
applies to only the equipment, process vents, storage vessels, or
transfer operations to which the referencing subparts apply. This part
does not extend applicability to equipment, process vents, storage
vessels, or transfer operations that are not regulated by the
referencing subpart.
(d) The provisions of 40 CFR part 60, subpart A; 40 CFR part 61,
subpart A; and 40 CFR part 63, subpart A, that are listed in table 1 of
this subpart still apply to owners or operators of regulated sources
expressly referenced to this part. The owner or operator shall comply
with the provisions in table 1 of this subpart in the column
corresponding to the referencing subpart. All provisions of 40 CFR part
60, subpart A; 40 CFR part 61, subpart A; and 40 CFR part 63, subpart
A, not expressly referenced in table 1 of this subpart do not apply,
and the provisions of this part apply instead, except that provisions
which were required to be met prior to implementation of this part 65
still apply.
(e) The provisions of the referencing subparts that are listed in
table 2 of this subpart still apply to owners or operators of regulated
sources expressly referenced to this part. The owner or operator shall
comply with the provisions in table 2 of this subpart in the row
corresponding to the referencing subpart. All provisions of the
referencing subparts not expressly referenced in table 2 to this
subpart do not apply and the provisions of this part apply instead,
except that provisions which were required to be met prior to
implementation of this part 65 still apply.
(f) Implementation date. Owners or operators who choose to comply
with this part shall comply by the dates specified in paragraph (f)(1)
of this section, as applicable, and shall meet the requirement in
paragraph (f)(2) of this section.
[[Page 78287]]
(1) Owners or operators shall implement this part as specified in
an implementation schedule or at initial startup. The implementation
date shall be established by mutual agreement with the Administrator or
delegated authority. The implementation schedule shall be included in
the source's title V permit. For non-title V sources, the
implementation schedule shall be proposed by the source in the Initial
Notification for Part 65 Applicability as specified in Sec. 65.5(c).
(2) There shall be no gaps in compliance between compliance with
the referencing subpart and compliance with this part.
(g) Transitioning out of this part. Owners or operators who decide
to no longer comply with this part and to comply with the provisions in
the referencing subpart instead shall comply with the following, as
applicable:
(1) This transition shall be carried out on a date established in a
title V permit or if the source is not a title V source, by a date
established by agreement with the Administrator or delegated authority.
The transition date shall be proposed in a title V permit amendment, or
for non-title V sources, in a periodic report or separate notice.
(2) There shall be no gaps in compliance between compliance with
this part and compliance with the referencing subpart provisions.
(h) Overlap with other subparts of this part. When provisions of
another subpart of this part conflict with the provisions of this
subpart, the provisions of the other subpart shall apply.
(i) Equipment assignment procedures. If specific items of equipment
(pumps, compressors, agitators, pressure relief devices, sampling
connection systems, open-ended valves or lines, valves, connectors,
instrumentation systems, surge control vessels, and bottoms receivers)
that are part of a process unit complying with this part are managed by
different administrative organizations (for example, different
companies, affiliates, departments, divisions, etc.), those items of
equipment may be aggregated with any process unit within the plant
site.
Sec. 65.2 Definitions.
All terms used in this part shall have the meaning given them in
the Act and in this section. If a term is defined both in this section
and in other parts that reference the use of this part, the term shall
have the meaning given in this section for purposes of this part. If a
term is not defined in the Act or in this section, the term shall have
the meaning given in the referencing subpart for purposes of this part.
The terms follow:
Act means the Clean Air Act (42 U.S.C. 7401 et seq.).
Administrator means the Administrator of the United States
Environmental Protection Agency (EPA) or his or her authorized
representative (for example, a State that has been delegated the
authority to implement the provisions of this part).
Approved permit program means a State permit program approved by
the Administrator as meeting the requirements of part 70 of this
chapter or a Federal permit program established in this chapter
pursuant to title V of the Act (42 U.S.C. 7661).
Automated continuous parameter monitoring system means a continuous
parameter monitoring system that automatically both records the
measured data and calculates hourly averages.
Automated monitoring and recording system means any means of
measuring values of monitored parameters and creating a hard copy or
computer record of the measured values that does not require manual
reading of monitoring instruments and manual transcription of data
values. Automated monitoring and recording systems include, but are not
limited to, computerized systems, strip charts, and circular charts.
Batch process means a process in which the equipment is fed
intermittently or discontinuously. Processing then occurs in this
equipment after which the equipment is generally emptied. Examples of
industries that use batch processes include pharmaceutical production
and pesticide production.
Batch product-process equipment train means the collection of
equipment (for example, connectors, reactors, valves, pumps) configured
to produce a specific product or intermediate by a batch process.
Boiler means any enclosed combustion device that extracts useful
energy in the form of steam and is not an incinerator or a process
heater. Boiler also means any industrial furnace as defined in 40 CFR
260.10.
Bottoms receiver means a tank that collects distillation bottoms
before the stream is sent for storage or for further downstream
processing.
By compound means by individual stream components, not carbon
equivalents.
Car-seal means a seal that is placed on a device that is used to
change the position of a valve (for example, from opened to closed) in
such a way that the position of the valve cannot be changed without
breaking the seal.
Closed vent system means a system that is not open to the
atmosphere and is composed of piping, ductwork, connections, and, if
necessary, flow inducing devices that transport gas or vapor from an
emission point to a control device. A closed vent system does not
include the vapor collection system that is part of any tank truck or
railcar or the loading arm or hose that is used for vapor return. For
transfer racks, the closed vent system begins at, and includes, the
first block valve on the downstream side of the loading arm or hose
used to convey displaced vapors.
Closed vent system shutdown means a work practice or operational
procedure that stops production from a process unit or part of a
process unit during which it is technically feasible to clear process
material from a closed vent system or part of a closed vent system
consistent with safety constraints and during which repairs can be
effected. An unscheduled work practice or operational procedure that
stops production from a process unit or part of a process unit for less
than 24 hours is not a closed vent system shutdown. An unscheduled work
practice or operational procedure that would stop production from a
process unit or part of a process unit for a shorter period of time
than would be required to clear the closed vent system or part of the
closed vent system of materials and start up the unit, and would result
in greater emissions than delay of repair of leaking components until
the next scheduled closed vent system shutdown, is not a closed vent
system shutdown. The use of spare equipment and technically feasible
bypassing of equipment without stopping production are not closed vent
system shutdowns.
Closed-loop system means an enclosed system that returns process
fluid to a process.
Closed-purge system means a system or combination of systems and
portable containers to capture purged liquids. Containers must be
covered or closed when not being filled or emptied.
Combustion device means an individual unit of equipment, such as a
flare, incinerator, process heater, or boiler, used for the combustion
of organic emissions.
Compliance date means the date by which a regulated source is
required to be in compliance with a relevant standard, limitation,
prohibition, or any federally enforceable requirement established by
the Administrator (or a State with an approved permit program) pursuant
to the Act.
Connector means flanged, screwed, or other joined fittings used to
connect two
[[Page 78288]]
pipelines or a pipeline and a piece of equipment. A common connector is
a flange. Joined fittings welded completely around the circumference of
the interface are not considered connectors for the purpose of this
regulation. For the purpose of reporting and recordkeeping, connector
means joined fittings that are not inaccessible, ceramic, or ceramic-
lined (for example, porcelain, glass, or glass-lined) as described in
Sec. 65.108(e)(2).
Continuous parameter monitoring system or CPMS means the total
equipment that may be required to meet the data acquisition and
availability requirements of this part used to sample, condition (if
applicable), analyze, and provide a record of process or control system
parameters.
Continuous record means documentation, either in hard copy or
computer-readable form, of data values measured at least once every 15
minutes and recorded at the frequency specified in Sec. 65.161(a).
Continuous seal means a seal that is designed to form a continuous
closure that completely covers the space between the wall of the
storage vessel and the edge of the floating roof. A continuous seal may
be a vapor-mounted, liquid-mounted, or metallic shoe seal. A continuous
seal may be constructed of fastened segments so as to form a continuous
seal.
Control device means any combustion device, recovery device, or any
combination of these devices used to comply with this part. Such
equipment or devices include, but are not limited to, absorbers, carbon
adsorbers, condensers, incinerators, flares, boilers, and process
heaters. For process vents (as defined in this section), recovery
devices are not considered control devices except for the recovery
devices specified in Sec. 65.63(a)(2)(ii). A fuel gas system is not a
control device. For a steam stripper, a primary condenser is not
considered a control device.
Control system means the combination of the closed vent system and
the control devices used to collect and control vapors or gases from a
regulated source.
Day means a calendar day.
Distance piece means an open or enclosed casing through which the
piston rod travels, separating the compressor cylinder from the
crankcase.
Double block and bleed system means two block valves connected in
series with a bleed valve or line that can vent the line between the
two block valves.
Ductwork means a conveyance system such as those commonly used for
heating and ventilation systems. It is often made of sheet metal and
often has sections connected by screws or crimping. Hard-piping is not
ductwork.
Emission point means an individual process vent, storage vessel,
transfer rack, wastewater stream, or equipment leak.
Empty or emptying means the removal of the stored liquid from a
storage vessel. Storage vessels where stored liquid is left on the
walls, as bottom clingage, or in pools due to bottom irregularities are
considered empty. Lowering of the stored liquid level, so that the
floating roof is resting on its legs, as necessitated by normal vessel
operation (for example, when changing stored material or when
transferring material out of the vessel for shipment) is not considered
emptying.
Equipment means each of the following that is subject to control
under the referencing subpart: pump, compressor, agitator, pressure
relief device, sampling connection system, open-ended valve or line,
valve, connector, and instrumentation system; and any control devices
or systems used to comply with subpart F of this part.
Equivalent method means any method of sampling and analyzing for an
air pollutant that has been demonstrated to the Administrator's
satisfaction to have a consistent and quantitatively known relationship
to the reference method under specified conditions.
External floating roof or EFR means a pontoon-type (noncontact) or
double-deck-type (contact) roof that is designed to rest on the stored
liquid surface in a storage vessel with no fixed roof.
Failure, EFR (referred to as EFR failure) is defined as any time
the external floating roof's primary seal has holes, tears, or other
openings in the shoe, seal fabric, or seal envelope; or the secondary
seal has holes, tears, or other openings in the seal or the seal
fabric; or the gaskets no longer close off the stored liquid surface
from the atmosphere; or a slotted membrane has more than 10 percent
open area.
Failure, internal floating roof type A (referred to as IFR type A
failure) means any time, as determined during visual inspection through
roof hatches, in which the internal floating roof is not resting on the
surface of the stored liquid inside the storage vessel and is not
resting on the leg supports; or there is stored liquid on the floating
roof; or there are holes, tears, or other openings in the seal or seal
fabric; or there are visible gaps between the seal and the wall of the
storage vessel.
Failure, internal floating roof type B (referred to as IFR type B
failure) means any time, as determined during internal inspections, the
internal floating roof's primary seal has holes, tears, or other
openings in the seal or the seal fabric; or the secondary seal (if one
has been installed) has holes, tears, or other openings in the seal or
the seal fabric; or the gaskets no longer close off the stored liquid
surface from the atmosphere; or a slotted membrane has more than 10
percent open area.
Fill or filling means the introduction of liquids into a storage
vessel, but not necessarily to complete capacity.
First attempt at repair, for the purposes of subparts F and G of
this part, means to take action for the purpose of stopping or reducing
leakage of organic material to the atmosphere, followed by monitoring
as specified in Sec. 65.104(b) and Sec. 65.143(c), as appropriate, to
verify whether the leak is repaired, unless the owner or operator
determines by other means that the leak is not repaired.
Fixed roof means a roof that is mounted (for example, permanently
affixed) on a storage vessel in a stationary manner and that does not
move with fluctuations in stored liquid level.
Flame zone means the portion of the combustion chamber in a boiler
or process heater occupied by the flame envelope.
Floating roof means a roof consisting of an external floating roof
or an internal floating roof that is designed to rest upon and is
supported by the stored liquid and is equipped with a continuous seal.
Flow indicator means a device that indicates whether gas flow is
present in a line, or whether the valve position would allow gas flow
to be present in a line.
Fuel gas means gases that are combusted to derive useful work or
heat.
Fuel gas system means the offsite and onsite piping and flow and
pressure control system that gathers gaseous stream(s) generated by
onsite operations, may blend them with other sources of gas, and
transports the gaseous stream for use as fuel gas in combustion devices
or in-process combustion equipment, such as furnaces and gas turbines,
either singly or in combination.
Group 1 process vent means a process vent for which the flow rate
is greater than or equal to 0.011 standard cubic meter per minute (0.39
cubic feet per minute); the total concentration is greater than or
equal to the appropriate value in table 1 of subpart D of this part,
and the total resource effectiveness index value, calculated according
to Sec. 65.64(h) is less than or equal to 1.0.
Group 2A process vent means a process vent that is not Group 1 or
[[Page 78289]]
Group 2B for which monitoring and recordkeeping are required to
demonstrate a total resource effectiveness index value greater than
1.0.
Group 2B process vent means a process vent that is not Group 1 or
Group 2A for which monitoring and recordkeeping are not required to
demonstrate a total resource effectiveness index value greater than
4.0, or which is exempt from control requirements due to the vent
stream's flow rate, regulated material concentration, or total resource
effectiveness index value.
Halogenated vent stream or halogenated stream means, for purposes
of this part, a vent stream determined to be halogenated by the
procedures specified in Sec. 65.85(c) for transfer racks and in
Sec. 65.64(g) for process vents, as applicable.
Halogens and hydrogen halides means hydrogen chloride (HCl),
chlorine (Cl2), hydrogen bromide (HBr), bromine
(Br2), and hydrogen fluoride (HF).
Hard-piping means pipe or tubing that is manufactured and installed
using good engineering judgment and standards, such as ASME B31.3,
Process Piping (available from the American Society of Mechanical
Engineers, PO Box 2900, Fairfield, NJ 07007-2900).
High-throughput transfer racks means those transfer racks that
transfer greater than or equal to a total of 11.8 million liters per
year (3.12 million gallons per year) of liquid containing regulated
material.
In food/medical service means that a piece of equipment in
regulated material service contacts a process stream used to
manufacture a Food and Drug Administration-regulated product where
leakage of a barrier fluid into the process stream would cause any of
the following:
(1) A dilution of product quality so that the product would not
meet written specifications;
(2) An exothermic reaction that is a safety hazard;
(3) The intended reaction to be slowed down or stopped; or
(4) An undesired side reaction to occur.
In gas/vapor service means that a piece of equipment in regulated
material service contains a gas or vapor when in operation.
In heavy liquid service means that a piece of equipment in
regulated material service is not in gas/vapor service or in light

regulated material service contains a liquid that meets the following
conditions:
(1) The vapor pressure of one or more of the organic compounds is
greater than 0.3 kilopascals at 20 deg.C (0.04 pounds per square inch
at 68 deg.F);
(2) The total concentration of the pure organic compound
constituents having a vapor pressure greater than 0.3 kilopascals at 20
deg.C (0.04 pounds per square inch at 68 deg.F) is equal to or
greater than 20 percent by weight of the total process stream; and
(3) The fluid is a liquid at operating conditions. (Note: Vapor
pressures may be determined by standard reference texts or American
Society for Testing and Materials (ASTM) D-2879, available from
American Society for Testing and Materials, 1916 Race Street,
Philadelphia, Pennsylvania 19103; or University Microfilms
International, 300 North Zeeb Road, Ann Arbor, Michigan 48106.)
In liquid service means that a piece of equipment in regulated
material service is not in gas/vapor service.
In regulated material service means, for the purposes of the
equipment leak provisions of subpart F of this part, equipment which
meets the definition of ``in volatile organic compound service,'' ``in
volatile hazardous air pollutant service,'' ``in benzene service,''
``in vinyl chloride service,'' or ``in organic hazardous air pollutant
service'' as defined in the referencing subpart.
In vacuum service means that equipment is operating at an internal
pressure that is at least 5 kilopascals (0.7 pounds per square inch)
below ambient pressure.
In-situ sampling systems means nonextractive samplers or in-line
samplers.
Incinerator means an enclosed combustion device that is used for
destroying organic compounds. Auxiliary fuel may be used to heat waste
gas to combustion temperatures. Any energy recovery section present is
not physically formed into one manufactured or assembled unit with the
combustion section; rather, the energy recovery section is a separate
section following the combustion section and the two are joined by
ducts or connections carrying flue gas. This energy recovery section
limitation does not apply to an energy recovery section used solely to
preheat the incoming vent stream or combustion air.
Initial startup means, for new or reconstructed sources, the first
time the source begins production. For additions or changes not defined
as a new source by an applicable referencing subpart, initial startup
means the first time additional or changed equipment is put into
operation. Initial startup does not include operation solely for
testing equipment. Initial startup does not include subsequent startup
(as defined in this section) of process units following malfunctions or
process unit shutdowns. Except for equipment leaks, initial startup
also does not include subsequent startups (as defined in this section)
of process units following changes in product for flexible operation
units or following recharging of equipment in batch operation.
Instrumentation system means a group of equipment components used
to condition and convey a sample of the process fluid to analyzers and
instruments for the purpose of determining process operating conditions
(for example, composition, pressure, flow). Valves and connectors are
the predominant type of equipment used in instrumentation systems;
however, other types of equipment may also be included in these
systems. Only valves nominally 0.5 inches and smaller in diameter and
connectors nominally 0.75 inches and smaller in diameter are considered
instrumentation systems for the purposes of subpart F of this part.
Intermediate change to monitoring means a modification to federally
required monitoring involving ``proven technology'' (generally accepted
by the scientific community as equivalent or better) that is applied on
a site-specific basis and that may have the potential to decrease the
stringency of the associated emission limitation or standard. Though
site-specific, an intermediate change may set a national precedent for
a source category and may ultimately result in a revision to the
federally required monitoring. Examples of intermediate changes to
monitoring include, but are not limited to:
(1) Use of a continuous monitoring system (CEMS) in lieu of a
parameter monitoring approach;
(2) Decreased frequency for non-continuous parameter monitoring or
physical inspections;
(3) Changes to quality control requirements for parameter
monitoring; and
(4) Use of an electronic data reduction system in lieu of manual
data reduction.
Intermediate change to test method means a within-method
modification to a federally enforceable test method involving ``proven
technology'' (generally accepted by the scientific community as
equivalent or better) that is applied on a site-specific basis and that
may have the potential to decrease the stringency of the associated
emission limitation or standard. Though site-specific, an intermediate
change
[[Page 78290]]
may set a national precedent for a source category and may ultimately
result in a revision to the federally enforceable test method. In order
to be approved, an intermediate change must be validated according to
EPA Method 301 (40 CFR part 63, appendix A) to demonstrate that it
provides equal or improved accuracy or precision. Examples of
intermediate changes to a test method include, but are not limited to:
(1) Modifications to a test method's sampling procedure including
substitution of sampling equipment that has been demonstrated for a
particular sample matrix; and use of a different impinger absorbing
solution;
(2) Changes in sample recovery procedures and analytical
techniques, such as changes to sample holding times and use of a
different analytical finish with proven capability for the analyte of
interest; and
(3) ``Combining'' a federally required method with another proven
method for application to processes emitting multiple pollutants.
Internal floating roof or IFR means a pontoon-type (noncontact) or
double-deck-type (contact) roof that is designed to rest or float on
the stored liquid surface inside a storage vessel that has a fixed
roof.
Liquid-mounted seal means a foam-or liquid-filled continuous seal
mounted in contact with the stored liquid.

program; and
(7) Use of alternative averaging times for reporting purposes.
Major change to test method means a modification to a federally
enforceable test method that uses ``unproven technology or procedures''
(not generally accepted by the scientific community) or is an entirely
new method (sometimes necessary when the required test method is
unsuitable). A major change to a test method may be site-specific or
may apply to one or more source categories and will almost always set a
national precedent. In order to be approved, a major change must be
validated according to EPA Method 301 (40 CFR part 63, appendix A).
Examples of major changes to a test method include, but are not limited
to:
(1) Use of an unproven analytical finish;

operational characteristics, physical constraints, or safety concerns
of an affected source.
(2) Examples of minor changes to monitoring include, but are not
limited to:

temperature fluctuation and thus protect the analytical
instrumentation.
Minor change to test method means:
(1) A modification to a federally enforceable test method that:
(i) Does not decrease the stringency of the emission limitation or
standard;
(ii) Has no national significance (e.g., does not affect
implementation of the applicable regulation in this part for other
affected sources, does not set a national precedent, and individually
does not result in a revision to the test method); and
(iii) Is site-specific, made to reflect or accommodate the
operational characteristics, physical constraints, or safety concerns
of an affected source.
(2) Examples of minor changes to a test method include, but are not
limited to:
(i) Field adjustments in a test method's sampling procedure, such
as a modified sampling traverse or location to avoid interference from
an obstruction in the stack, increasing the sampling time or volume,
use of additional impingers for a high moisture situation, accepting
particulate emission results for a test run that was conducted with a
lower than specified temperature, substitution of a material in the
sampling train that has been demonstrated to be more inert for the

device. This release can be one release or a series of releases over a
short time period.
Pressure relief device or valve means a device used to prevent
operating pressures from exceeding the maximum allowable working
pressure of the process equipment. A common pressure relief device is a
spring-loaded pressure relief valve. Devices that are actuated either
by a pressure of less than or equal to 2.5 pounds per square inch gauge
or by a vacuum are not pressure relief devices.
Primary fuel means the fuel that provides the principal heat input
to the device. To be considered primary, the fuel must be able to
sustain operation without the addition of other fuels.
Process heater means an enclosed combustion device that transfers
heat liberated by burning fuel directly to process streams or to heat
transfer liquids other than water. A process heater may, as a secondary
function, heat water in unfired heat recovery sections.

materials and to manufacture an intended product.
Process unit shutdown means a work practice or operational
procedure that stops production from a process unit or part of a
process unit during which it is technically feasible to clear process
material from a process unit or part of a process unit consistent with
safety constraints and during which repairs can be effected. An
unscheduled work practice or operational procedure that stops
production from a process unit or part of a process unit for less than
24 hours is not a process unit shutdown. An unscheduled work practice
or operational procedure that would stop production from a process unit
or part of a process unit for a shorter period of time than would be
required to clear the process unit or part of the process unit of
materials and start up the unit, and would result in greater emissions
than delay of repair of leaking components until the next scheduled
process unit shutdown is not a process unit shutdown. The use of spare
equipment and technically feasible bypassing of equipment without
stopping production are not process unit shutdowns.

and normally used for the purpose of recovering chemicals for fuel
value (i.e., net positive heating value), use, reuse, or for sale for
fuel value, use, or reuse. Equipment capable of and used for the
purpose of recovering chemicals, but not normally for use, reuse or
sale, are not recovery devices but are control devices. Examples of
equipment that may be recovery devices include absorbers, carbon
adsorbers, condensers, oil-water separators or organic-water
separators, or organic removal devices such as decanters, strippers, or
thin-film evaporation units.

requirement established pursuant
[[Page 78292]]
to this part, or 40 CFR part 60, 61, or 63.
Relief device or valve means a device or valve used only to release
an unplanned, nonroutine discharge. A relief device or valve discharge
can result from an operator error, a malfunction such as a power
failure or equipment failure, or other unexpected cause that requires
immediate venting of gas from process equipment in order to avoid
safety hazards or equipment damage.
Repaired means, for the purposes of subparts F and G of this part,
that equipment meets the following conditions:

conveyed to any enclosed portion of a process unit where the emissions
are predominantly recycled and/or consumed in the same manner as a
material that fulfills the same function in the process and/or
transformed by chemical reaction into materials that are not regulated
materials and/or incorporated into a product; and/or recovered.
Run means one of a series of emission or other measurements needed
to determine emissions for a representative operating period or cycle
as specified in this part. Unless otherwise specified, a run may be
either intermittent or continuous within the limits of good engineering
practice.
Sampling connection system means an assembly of equipment within a
process unit used during periods of representative operation to take
samples of the process fluid. Equipment used to take nonroutine grab
samples is not considered a sampling connection system.
Secondary fuel means a fuel fired through a burner other than the
primary fuel burner that provides supplementary heat in addition to the
heat provided by the primary fuel.
Sensor means a device that measures a physical quantity or the
change in a physical quantity, such as temperature, pressure, flow

Set pressure means, for the purposes of subparts F and G of this
part, the pressure at which a properly operating pressure relief device
begins to open to relieve atypical process system operating pressure.
Shutdown means the cessation of operation of a regulated source
(for example, chemical manufacturing process unit or a reactor, air
oxidation reactor, distillation unit) and equipment required or used to
comply with this part, or the emptying and degassing of a storage
vessel. Shutdown is defined here for purposes including, but not
limited to, periodic maintenance, replacement of equipment, or repair.
Shutdown does not include the routine rinsing or washing of equipment
in batch operation between batches.

Startup means the setting into operation of a regulated source (for
example, chemical manufacturing process unit or a reactor, air
oxidation reactor, distillation unit, a storage vessel after emptying
and degassing) and/or equipment required or used to comply with this
part. Startup includes initial startup, operation solely for testing
equipment, the recharging of equipment in batch operation, and
transitional conditions due to changes in product for flexible
operation units.
State means all non-Federal authorities, including local agencies,
interstate associations, and statewide programs, that have delegated
authority to implement the provisions of this part; the referencing
subparts; and/or the permit program established under part 70 of this
chapter. The term State shall have its conventional meaning where clear
from the context.

Total organic compounds or TOC means those compounds measured
according to the procedures specified in Sec. 65.64(c) and
Sec. 65.158(b)(3)(ii)(A), as applicable. Those compounds that the
Administrator has determined do not contribute appreciably to the
formation of ozone and that are specifically excluded from the
definition of volatile organic compound at 40 CFR 51.100(s), as
amended, are to be excluded for the purposes of measuring the hourly
emission rate as required in Sec. 65.64(f) for process vents subject to
subpart III, NNN, or RRR of part 60 of this chapter.
Total resource effectiveness index value or TRE index value means a
calculated value used to determine whether control is required for a
process vent. It is based on process vent flow rate, emission rate of
regulated material, net heating value, and corrosion properties
(halogenated compound content), as quantified by the equations given
under Sec. 65.64(h).
Vapor balancing system means a piping system that is designed to
collect regulated material vapors displaced from tank trucks or
railcars during loading and to route the collected regulated material
vapors to the storage vessel from which the liquid being loaded
originated, or to another storage vessel connected by a common header;
or to compress and route to a process or a fuel gas system the
collected regulated material vapors.
Vapor-mounted seal means a continuous seal that is mounted so that
there is a vapor space between the stored liquid and the bottom of the
seal.
Visible emission means the observation of an emission of opacity or

Sec. 65.3 Compliance with standards and operation and maintenance
requirements.
(a) Requirements. (1) Except as provided in paragraph (a)(2) of
this section, the emission standards and established parameter ranges
of this part
[[Page 78293]]
shall apply at all times except during periods of startup, shutdown (as
defined in Sec. 65.2), malfunction, or nonoperation of the regulated
source (or specific portion thereof) resulting in cessation of the
emissions to which this part applies. However, if a startup, shutdown,
malfunction, or period of nonoperation of one portion of a regulated
source 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 part during the startup, shutdown, malfunction, or
period of nonoperation. For example, if there is an over pressure in
the reactor area, a storage vessel in a chemical manufacturing process
unit would still be required to be controlled in accordance with
subpart C of this part. Similarly, the degassing of a storage vessel
would not affect the ability of a process vent to meet the requirements
of subpart D or G of this part.
(2) Sections 65.106 through 65.118 shall apply at all times except
during periods of startup or shutdown (as defined in Sec. 65.2),
malfunction, process unit shutdown (as defined in Sec. 65.2), or
nonoperation of the regulated source (or specific portion thereof) in
which the lines are drained and depressurized resulting in cessation of
the emissions to which subpart F of this part applies.
(3) During startups, shutdowns, and malfunctions when the emission
standards of this part do not apply pursuant to paragraphs (a)(1) and
(2) of this section, the owner or operator shall implement, to the
extent reasonably available, measures to prevent or minimize emissions
in excess of those that would have occurred if there were no startup,
shutdown, or malfunction and the owner or operator complied with the
relevant provisions of this part. The measures to be taken shall be
identified in the applicable startup, shutdown, and malfunction plan
and may include, but are not limited to, air pollution control
technologies, recovery technologies, work practices, pollution
prevention, monitoring, and/or changes in the manner of operation of
the regulated source. Backup control devices are not required but may
be used if available. This paragraph (a)(3) does not apply to Group 2A
or Group 2B process vents.
(4) Malfunctions shall be corrected as soon as practical after
their occurrence in accordance with the startup, shutdown, and
malfunction plan required in Sec. 65.6(a). This paragraph (a)(4) does
not apply to Group 2A or Group 2B process vents.
(5) Operation and maintenance requirements established pursuant to
section 112 of the Act are enforceable independent of emissions
limitations or other requirements in relevant standards.
(b) Compliance determination procedures.--(1) Parameter monitoring:
Compliance with operating conditions. The parameter monitoring data for
emission points that are required to perform continuous monitoring
shall be used to determine compliance with the required operating
conditions for the monitored control devices or recovery devices. For
each excursion, except for excused excursions and as provided for in
paragraph (b)(2) of this section, the owner or operator shall be deemed
to have failed to have applied the control in a manner that achieves
the required operating conditions. Excused excursions are provided for
in Sec. 65.156(d)(2).
(2) Parameter monitoring: Excursions. If the conditions of
paragraph (b)(2)(i) or (ii) of this section are met, an excursion is
not a violation and, in cases where continuous monitoring is required,
the excursion does not count toward the number of excused excursions.
Nothing in this paragraph (b)(2) shall be construed to allow or excuse
a monitoring parameter excursion caused by any activity that violates
other applicable provisions of this part.
(i) During periods of startup, shutdown, or malfunction (and the
source is operated during such periods in accordance with the source's
startup, shutdown, and malfunction plan as required by Sec. 65.6(a)), a
monitoring parameter is outside its established range or monitoring
data cannot be collected; or
(ii) During periods of nonoperation of the regulated source or
portion thereof (resulting in cessation of the emissions to which the
monitoring applies).
(3) Operation and maintenance procedures. Determination of whether
acceptable operation and maintenance procedures are being used will be
based on information available to the Administrator that may include,
but is not limited to, monitoring results, review of operation and
maintenance procedures (including the startup, shutdown, and
malfunction plan, if applicable, required in Sec. 65.6(a), as
applicable), review of operation and maintenance records, inspection of
the regulated source, and alternatives approved as specified in
Sec. 65.7.
(4) Emissions standards. Paragraphs (b)(4)(i) and (ii) of this
section shall govern the use of data, tests, and requirements to
determine compliance with emissions standards. Paragraphs (b)(4)(i) and
(ii) do not apply to Group 2A or Group 2B process vents. Compliance
with design, equipment, work practice, and operational standards,
including those for equipment leaks, shall be determined according to
paragraph (b)(5) of this section.
(i) Performance test. The Administrator will determine compliance
with emission standards of this part based on the results of
performance tests conducted according to the procedures specified in
subpart G of this part, unless otherwise specified in a subpart of this
part.
(ii) Operation and maintenance requirements. The Administrator will
determine compliance with emission standards of this part by evaluation
of an owner or operator's conformance with operation and maintenance
requirements, including the evaluation of monitoring data, as specified
in subparts of this part.
(5) Design, equipment, work practice, or operational standards.
Paragraphs (b)(5)(i) and (ii) do not apply to Group 2A or Group 2B
process vents.
(i) Records and inspection. The Administrator will determine
compliance with design, equipment, work practice, or operational
standards by review of records, inspection of the regulated source, and
other procedures specified in this part.
(ii) Operation and maintenance. The Administrator will determine
compliance with design, equipment, work practice, or operational
standards by evaluation of an owner or operator's conformance with
operation and maintenance requirements as specified in paragraph (a) of
this section, in other subparts of this part, and in applicable
provisions of Sec. 65.6(b).
(c) Finding of compliance. The Administrator will make a finding
concerning a regulated source's compliance with an emission standard,
design standard, work practice, operational standard or operating and
maintenance requirement as specified in paragraphs (a) and (b) 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.
Standards in this part and methods of determining compliance are given
in metric units followed by the equivalents in English units. The
Administrator will make findings of
[[Page 78294]]
compliance with the standards of this part using metric units.
(d) Compliance times. All terms that define a period of time for
completion of required tasks (for example, weekly, monthly, quarterly,
annually) unless specified otherwise in the section or paragraph that
imposes the requirement refer to the standard calendar periods.
(1) Notwithstanding time periods specified for completion of
required tasks, time periods may be changed by mutual agreement between
the owner or operator and the Administrator as specified in
Sec. 65.5(h)(3) (for example, a period could begin on the compliance
date or another date, rather than on the first day of the standard
calendar period). For each time period that is changed by agreement,
the revised period applies until it is changed. A new request is not
necessary for each recurring period.
(2) When the period specified for compliance is a standard calendar
period, if the initial compliance date occurs after the beginning of
the period, compliance shall be required according to the schedule
specified in the following paragraphs, as appropriate:
(i) Compliance shall be required before the end of the standard
calendar period within which the compliance deadline occurs if there
remain at least 3 days for tasks that must be performed weekly, at
least 2 weeks for tasks that must be performed monthly, at least 1
month for tasks that must be performed each quarter, or at least 3
months for tasks that must be performed annually; or
(ii) In all other cases, compliance shall be required before the
end of the first full standard calendar period after the period within
which the initial compliance deadline occurs.
(3) In all instances where a provision requires completion of a
task during each of multiple successive periods, an owner or operator
may perform the required task at any time during the specified period
provided the task is conducted at a reasonable interval after
completion of the task during the previous period.
Sec. 65.4 Recordkeeping.
(a) Maintaining notifications, records, and reports. Except as
provided in paragraph (b) of this section, the owner or operator of
each regulated source subject to this part shall keep copies of
notifications, reports, and records required by this part for the
length of time specified in the following, as applicable:
(1) If an owner or operator is required to obtain or operate a
regulated source under a title V permit, then all applicable
notifications, reports, and records for that regulated source shall be

For this alternative, the kind of emission point
[[Page 78295]]
in the process unit that will comply must also be identified.
(d) Initial Compliance Status Report--(1) Contents. The owner or
operator shall submit an Initial Compliance Status Report for each
regulated source subject to this part containing the information
specified in the subparts of this part. Unless the required information
has already been submitted under requirements of the applicable
referencing subpart, this information can be submitted as part of a
title V permit application or amendment.
(2) Due date. The owner or operator shall submit the Initial
Compliance Status Report for each regulated source within 240 days
after the applicable compliance date specified in the referencing
subparts, or within 60 days after the completion of the initial
performance test or initial compliance determination, whichever is
earlier. Initial compliance Status Reports may be combined for multiple
regulated sources as long as the due date requirements for all sources
covered in the combined report are met.
(e) Periodic reports. The owner or operator of a source subject to
monitoring requirements of this part or to other requirements of this
part where periodic reporting is specified, shall submit a periodic
report.
(1) Contents. Periodic reports shall include all information
specified in subparts of this part.
(2) Due date. The periodic report shall be submitted semiannually
no later than 60 calendar days after the end of each 6-month period.
The first report shall be submitted as specified in the following, as
applicable:
(i) The first report shall be submitted no later than the last day
of the month that includes the date 8 months after the date the source
became subject to this part or since the last part 60, 61, or 63
periodic report was submitted for the applicable requirement, whichever
is earlier.
(ii) For sources electing to comply with the CAR at initial
startup, the first report shall cover the 6 months after the Initial
Compliance Status Report is due. The first report shall be submitted no
later than the last day of the month that includes the date 8 months
after the Initial Compliance Status Report is due.
(3) Overlap with title V reports. Information required by this
part, which is submitted with a title V periodic report, need not also
be included in a subsequent periodic report required by this part. The
title V report shall be referenced in the periodic report required by
this part.
(f) General report content. All reports and notifications submitted
pursuant to this part, including reports that combine information from
this part and a referencing subpart, shall include the following
information:
(1) The name, address, and telephone number (fax number may also be
provided) of the owner or operator.
(2) The name, address and telephone number of the person to whom
inquiries should be addressed, if different than the owner/operator.
(3) The address (physical location) of the reporting facility.
(4) Identification of each regulated source covered in the
submission and identification of which subparts (referencing subparts
and this part 65) options from this part are applicable to that
regulated source. Summaries and groupings of this information are
permitted.
(g) Report and notification submission--(1) Submission. All reports
and notifications required under this part shall be sent to the
Administrator at the appropriate EPA Regional Office and to the
delegated State authority, except that requests for permission to use
an alternative means of emission limitation as provided for in
Sec. 65.8(a) shall be submitted to the Director of the EPA Office of
Air Quality Planning and Standards, U.S. Environmental Protection
Agency, MD-10, Research Triangle Park, North Carolina, 27711. The EPA
Regional Office may waive the requirement to receive a copy of any
reports or notifications at its discretion.
(2) Submission of copies. If any State requires a notice that
contains all the information required in a report or notification
listed in this part, an owner or operator may send the appropriate EPA
Regional Office a copy of the report or notification sent to the State
to satisfy the requirements of this part for that report or
notification.
(3) Method of submission. Wherever this subpart specifies
``postmark'' dates, submittals may be sent by methods other than the
U.S. Mail (for example, by fax or courier). Submittals shall be sent on
or before the specified date.
(4) Submission by electronic media. If acceptable to both the
Administrator and the owner or operator of a source, reports may be
submitted on electronic media.
(h) Adjustment to timing of submittals and review of required
communications--(1) Alignment with title V submission. An owner or
operator may submit periodic reports required by this part on the same
schedule as the title V periodic report for the facility. The owner or
operator using this option need not obtain prior approval, but must
assure no reporting gaps from the last periodic report for the relevant
standards. The owner or operator shall clearly identify the change in
reporting schedule in the first report filed under paragraph (h) of
this section. The requirements of paragraph (e) of this section are not
waived when implementing this change.
(2) Request for adjustment. An owner or operator may arrange by
mutual agreement (which may be a standing agreement) with the
Administrator a common schedule on which periodic reports required by
this part shall be submitted throughout the year as long as the
reporting period is not extended. 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
practical 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. A request for a change to the periodic
reporting schedule need only be made once for every schedule change and
not once for every semiannual report submitted.
(3) Approval of request for adjustment. 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) Notification of delay. If the Administrator is unable to meet a
specified deadline, the owner or operator will be notified of any
significant delay and informed of the amended schedule.
(i) Unless already submitted in a previous report, an owner or
operator shall report in a title V permit application or as otherwise
specified by the permitting authority, the information listed in
paragraphs (i)(1) through (5) of this section. This information shall
be submitted to the Administrator if the regulated source is not a
title V source.
(1) A list designating each emission point complying with subparts
C through G of this part and whether each process vent is Group 1,
Group 2A, or Group 2B.
(2) The control technology or method of compliance that will be
applied to each emission point.
[[Page 78296]]
(3) A statement that the compliance demonstration, monitoring,
inspection, recordkeeping, and reporting provisions in subparts C
through G of this part that are applicable to each emission point will
be implemented beginning on the date of compliance as specified in the
referencing subpart.
(4) The monitoring information in Sec. 65.162(e) if, for any
emission point, the owner or operator of a source seeks to comply
through use of a control technique other than those for which
monitoring parameters are specified in Secs. 65.148 through 65.154.
(5) Any requests for alternatives to the continuous operating
parameter monitoring and recordkeeping provisions, as specified in
Sec. 65.162(d).
Sec. 65.6 Startup, shutdown, and malfunction plan and procedures.
(a) Paragraphs (b) and (c) of this section do not apply to Group 2A
or Group 2B process vents.
(b) Startup, shutdown, and malfunction plan. (1) Description and
purpose of plan. The owner or operator of a regulated source shall
develop and implement a written startup, shutdown, and malfunction plan
that describes, in detail, procedures for operating and maintaining the
regulated 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.
The plan shall also address routine or otherwise predictable CPMS
malfunctions. This plan shall be developed by the owner or operator by
the regulated source's implementation date as specified in
Sec. 65.1(f), or for sources referenced from 40 CFR part 63, subpart F,
by the compliance date specified in that subpart. The requirement to
develop and implement this plan shall be incorporated into the source's
title V permit. This requirement is optional for equipment that must
comply with subpart F of this part. It is not optional for equipment
equipped with a closed vent system and control device subject to
subpart G of this part. The purposes of the startup, shutdown, and
malfunction plan are described in the following:
(i) To ensure that owners or operators are prepared to correct
malfunctions as soon as practical after their occurrence in order to
minimize excess emissions of regulated material (excess emissions are
defined in Sec. 65.3(a)(4)); and
(ii) To 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).
(2) Operation of source. During periods of startup, shutdown, and
malfunction, the owner or operator of a regulated source shall operate
and maintain such source (including associated air pollution control
equipment and CPMS) in accordance with the procedures specified in the
startup, shutdown, and malfunction plan developed under paragraph
(b)(1) of this section.
(3) Use of additional procedures. To satisfy the requirements of
this section to develop a startup, shutdown, and malfunction plan, the
owner or operator may use the regulated 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.
(4) Revisions to the plan. Based on the results of a determination
made under Sec. 65.3(b)(3), the Administrator may require that an owner
or operator of a regulated 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 is inadequate as
specified in the following:
(i) Does not address a startup, shutdown, and malfunction event of
the CPMS, the air pollution control equipment, or the regulated source
that has occurred; or
(ii) Fails to provide for the operation of the regulated source
(including associated air pollution control equipment and CPMS) during
a startup, shutdown, and malfunction event in a manner consistent with
good air pollution control practices for minimizing emissions to the
extent practical; or
(iii) Does not provide adequate procedures for correcting
malfunctioning process and/or air pollution control equipment as
quickly as practicable; or
(iv) Does not provide adequate measures to prevent or minimize
excess emissions to the extent practical as specified and defined in
Sec. 65.3(a)(4).
(5) Additional malfunction plan requirements. 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 regulated source during similar malfunction events, and
a program of corrective action for similar malfunctions of process or
air pollution control equipment or CPMS.
(6) Retain plan on site. The current plan must be kept on site at
all times.
(c) Periodic startup, shutdown, and malfunction reports. During the
reporting period, reports shall only be required for startup, shutdown,
and malfunction during which excess emissions as defined in
Sec. 65.3(a)(4) occur. A startup, shutdown, and malfunction report can
be submitted as part of a periodic report required under Sec. 65.5(e),
or on a more frequent basis if specified otherwise in a relevant
standard or as established otherwise by the permitting authority in the
source's title V permit. The startup, shutdown, and malfunction report
shall be delivered or postmarked by the 30th day following the end of
each calendar half (or other calendar reporting period, as
appropriate), unless the information is submitted with the periodic
report. The report shall include the following information, as
appropriate:
(1) The name, title, and signature of the owner or operator or
other responsible official certifying its accuracy.
(2) The number of startup, shutdown, malfunction events and the
total duration of all periods of startup, shutdown, and malfunction for
the reporting period.
(3) If actions taken by an owner or operator during a startup,
shutdown, and malfunction of a regulated source, or of a control device
or monitoring system required for compliance (including actions taken
to correct a malfunction) are consistent with the procedures specified
in the source's startup, shutdown, and malfunction plan, then the owner
or operator shall state such information in a startup, shutdown, and
malfunction report.
(4) If at any time an action taken by an owner or operator, during
a startup, shutdown, or malfunction (including actions taken to correct
a malfunction) during which excess emissions occur, as defined in
Sec. 65.3(a)(4), is not consistent with the procedures specified in the
regulated source's startup, shutdown, and malfunction plan, the owner
or operator shall report the actions taken for that event as part of
the periodic report. The report shall explain the circumstances of the
event, the reasons for not following the startup, shutdown, and
malfunction plan, and whether any
[[Page 78297]]
excess emissions and/or parameter monitoring exceedances are believed
to have occurred.
Sec. 65.7 Monitoring, recordkeeping, and reporting waivers and
alternatives.
(a) Waiver of recordkeeping or reporting requirements.--(1) Waiver
application. The owner or operator may apply for a waiver from
recordkeeping or reporting requirements if the regulated source is
achieving the relevant standard(s), or the source is operating under an
extension of compliance under 40 CFR 63.6(i), or a waiver of compliance
under 40 CFR 61.10(b), or the owner or operator has requested an
extension or waiver of compliance and the Administrator is still
considering that request. The waiver application shall be submitted in
writing to the Administrator.
(2) Extension of compliance request. If an application for a waiver
of recordkeeping or reporting is made, the application shall accompany
the request for an extension of compliance under 40 CFR 63.6(i) or the
request for a waiver of compliance under 40 CFR 61.10(b), any required
compliance progress report or compliance status report required in the
source's title V permit application or a permit modification
application, or a periodic report required under this part, 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.
(3) Approval or denial of waiver. The Administrator will approve or
deny a request for a waiver of recordkeeping or reporting requirements
when performing one of the following actions:
(i) Approves or denies an extension of compliance under 40 CFR
63.6(i) or a waiver of compliance under 40 CFR 61.10(b); or
(ii) Makes a determination of compliance following the submission
of a required compliance status report or periodic report; or
(iii) Makes a determination of suitable progress toward compliance
following the submission of a compliance progress report, whichever is
applicable.
(4) Waiver conditions. A waiver of any recordkeeping or reporting
requirement granted under this paragraph (a) may be conditioned on
other recordkeeping or reporting requirements deemed necessary by the
Administrator.
(5) Waiver cancellation. 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 regulated source.
(b) Requests for approval of alternative monitoring or
recordkeeping. An owner or operator may submit a written request for
approval to use alternatives to the monitoring or recordkeeping
provisions of this part. For process vents and transfer racks, except
low-throughput transfer racks, the provisions in paragraph (c) of this
section shall govern the review and approval of requests. In addition,
the application shall include information justifying the owner or
operator's request for an alternative monitoring or recordkeeping
method, such as the technical or economic infeasibility, or the
impracticality, of the regulated source using the required method. For
storage vessels and low throughput transfer racks, owners and operators
shall comply with the requirements of Sec. 65.145(b) for preparing and
submitting a design evaluation. For equipment leaks, owners and
operators shall comply with the recordkeeping requirements of
Sec. 65.163(d).
(c) Approval or denial of request to use alternative monitoring or
recordkeeping. The Administrator will notify the owner or operator of
approval or intention to deny approval of the request to use an
alternative monitoring or recordkeeping method within 90 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 method, the
Administrator will notify the applicant of the Administrator's
intention to disapprove the request together with the following:
(1) Notice of the information and findings on which the intended
disapproval is based; and
(2) 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 the
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.
(d) Use of an alternative monitoring or recordkeeping method. (1)
The owner or operator of a regulated source is subject to the
monitoring and recordkeeping requirements of the relevant standard
unless permission to use an alternative monitoring or recordkeeping
method requested under paragraph (b) of this section or Sec. 65.162(d)
has been granted by the Administrator. Once an alternative is approved,
the owner or operator shall use the alternative for the emission points
or regulated sources cited in the approval and shall meet the
monitoring and recordkeeping requirements of the relevant standard for
all other emission points or regulated sources.
(2) If the Administrator approves the use of an alternative
monitoring or recordkeeping method for a regulated source under
paragraph (c) of this section, the owner or operator of such source
shall continue to use the alternative monitoring or recordkeeping
method unless he or she receives approval from the Administrator to use
another method.
(3) If the Administrator finds reasonable grounds to dispute the
results obtained by an alternative monitoring or recordkeeping method,
requirement, or procedure, the Administrator may require the use of a
method, requirement, or procedure specified in the relevant standard.
If the results of the specified and alternative methods, requirements,
or procedures do not agree, the results obtained by the specified
method, requirement, or procedure shall prevail.
Sec. 65.8 Procedures for approval of alternative means of emission
limitation.
(a) Alternative means of emission limitation. An owner or operator
may request a determination of equivalence for an alternative means of
emission limitation to the requirements of design, equipment, work
practice, or operational standards of this part. If, in the judgment of
the Administrator, an alternative means of emission limitation will
achieve a reduction in regulated material emissions at least equivalent
to the reduction in emissions from that source achieved under any
design, equipment, work practice, or operational standards (but not
performance standards) in 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 such notice shall be published only after public notice and
an opportunity for a hearing.
(b) Content of submittal. (1) In order to obtain approval, 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
[[Page 78298]]
equivalent emission reductions. An owner or operator seeking permission
to use an alternative means of compliance who has not previously
performed testing shall also submit a proposed test plan. If the owner
or operator seeks permission to use an alternative means of compliance
based on previously performed testing, they shall submit the results of
that testing, a description of the procedures followed in testing or
monitoring, and a description of pertinent conditions during testing or
monitoring.
(2) The owner or operator who requests an alternative means of
emission limitation shall submit a description of the proposed testing,
monitoring, recordkeeping, and reporting that will be used and the
proposed basis for demonstrating compliance.
(3) For storage vessels, the owner or operator shall include the
results of actual emissions tests using full-size or scale-model
storage vessels that accurately collect and measure all regulated
material emissions using a given control technique, and that accurately
simulate wind and account for other emission variables such as
temperature and barometric pressure, or an engineering analysis that
the Administrator determines is an accurate method of determining
equivalence.
(4) For proposed alternatives to equipment leak requirements, the
owner or operator shall also submit the information and meet the
requirements for alternative means of emission limitation specified in
Sec. 65.102(b) (alternative means of emission limitation).
(c) Manufacturers of equipment used to control equipment leaks of a
regulated material may request a determination of equivalence for an
alternative means of emission limitation for equipment leaks, as
specified in Sec. 65.102(c).
(d) Compliance. If the Administrator makes a determination that a
means of emission limitation is a permissible alternative to the
requirements of design, equipment, work practice, or operational
standards of this part, the owner or operator shall either comply with
the alternative or comply with the requirements of this part.
Sec. 65.9 Availability of information and confidentiality.
(a) Availability of information. The availability to the public of
information provided to, or otherwise obtained by, the Administrator
under this part shall be governed by part 2 of this chapter. With the
exception of information protected under part 2 of this chapter, all
reports, records, and other information collected by the Administrator
under this part are available to the public. In addition, a copy of
each permit application, compliance plan (including the schedule of
compliance), initial compliance status report, periodic report, and
title V permit is available to the public, consistent with protections
recognized in section 503(e) of the Act.
(b) Confidentiality. (1) If an owner or operator is required to
submit information entitled to protection from disclosure under section
114(c) of the Act, the owner or operator may submit such information
separately. The requirements of section 114(c) shall apply to such
information.
(2) The contents of a title V permit shall not be entitled to
protection under section 114(c) of the Act; however, information
submitted as part of an application for a title V permit may be
entitled to protection from disclosure.
Sec. 65.10 State authority.
(a) The provisions of this part shall not be construed in any
manner to preclude any State or political subdivision thereof from
adopting and enforcing any emission standard or limitation applicable
to a regulated source, provided that such standard, limitation,
prohibition, or other regulation is not less stringent than the
standard applicable to such a regulated source.
(b) The provisions of this part shall not be construed in any
manner to preclude any State or political subdivision thereof from
requiring the owner or operator of a regulated source to obtain
permits, licenses, or approvals prior to initiating construction,
modification, or operation of such a regulated source.
Sec. 65.11 Circumvention and prohibited activities.
(a) Circumvention. (1) No owner or operator subject to the
provisions of this part shall build, erect, install, or use any
article, machine, equipment, or process to conceal an emission that
would otherwise constitute noncompliance with a relevant standard. Such
concealment includes, but is not limited to, the following:
(1) The use of diluents to achieve compliance with a relevant
standard based on the concentration of a pollutant in the effluent
discharged to the atmosphere; and
(2) The fragmentation of an operation for the purpose of avoiding
regulation by a relevant standard.
(b) Prohibited activities. (1) No owner or operator subject to the
provisions of this part shall operate any regulated source in violation
of the requirements of this part except under the following provisions:
(i) An extension or waiver of compliance granted by the
Administrator under an applicable part; or
(ii) An extension of compliance granted under an applicable part by
a State with an approved permit program; or
(iii) An exemption from compliance granted by the President under
section 112(i)(4) of the Act.
(2) After the effective date of an approved permit program in a
State, no owner or operator of a regulated source in that State who is
required under an applicable part to obtain a title V permit shall
operate such source except in compliance with the provisions of this
part and the applicable requirements of the permit program in that
State.
(3) An owner or operator of a regulated source who is subject to an
emission standard promulgated under this part or a referencing part
shall comply with the requirements of that standard by the date(s)
established in the applicable subpart(s) (including this subpart)
regardless of whether the following criteria are met:
(i) A title V permit has been issued to that source; or
(ii) If a title V permit has been issued to that source, whether
such permit has been revised or modified to incorporate the emission
standard.
(c) Severability. Notwithstanding any requirement incorporated into
a title V permit obtained by an owner or operator subject to the
provisions of this part, the provisions of this part are federally
enforceable.
Sec. 65.12 Delegation of authority.
(a) In delegating implementation and enforcement authority to a
State under sections 111(c) and 112(l) of the Act, the authorities
contained in paragraph (b) of this section shall be retained by the
Administrator and not transferred to a State.
(b) Authorities that will not be delegated to States: Secs. 65.8,
65.46, 65.102, 65.156(b)(l)(ii), and 65.158(a)(2)(ii).

(ii) Agitators in gas/vapor service and in light liquid service
shall be observed pursuant to Sec. 65.109(b)(3) or (e)(1)(v).
(b) Instrument monitoring methods. Instrument monitoring as
required under this subpart shall comply with the requirements
specified in paragraphs (b)(1) through (6) of this section.
(1) Monitoring method. Monitoring shall comply with Method 21 of
appendix A of 40 CFR part 60, except as otherwise provided in this
section.
(2) Detection instrument performance criteria. (i) Except as
provided for in paragraph (b)(2)(ii) of this section, the detection
instrument shall meet the performance criteria of Method 21 of appendix
A of 40 CFR part 60, except the instrument response factor criteria in
section 3.1.2(a) of Method 21 shall be for the representative
composition of the process fluid not each individual organic compound
in the stream. For process streams that contain nitrogen, air, water,
or other inerts that are not organic hazardous air pollutants or
volatile organic compounds, the response factor shall be determined on
an inert-free basis. The response factor may be determined at any
concentration for which monitoring for leaks will be conducted.
Maintain the record specified by Sec. 65.119(b)(8).
(ii) If no instrument is available at the plant site that will meet
the performance criteria specified in paragraph (b)(2)(i) of this
section, the instrument readings may be adjusted by multiplying by the
representative response factor of the process fluid calculated on an
inert-free basis as described in paragraph (b)(2)(i) of this section.
(3) Detection instrument calibration procedure. The detection
instrument shall be calibrated before use on each day of its use by the
procedures specified in Method 21 of appendix A of 40 CFR part 60.
(4) Detection instrument calibration gas. Calibration gases shall
be zero air (less than 10 parts per million of hydrocarbon in air) and
the gases specified in paragraph (b)(4)(i) of this section except as
provided in paragraph (b)(4)(ii) of this section.
(i) Mixtures of methane in air at a concentration no more than
2,000 parts per million greater than the leak definition concentration
of the equipment monitored. If the monitoring instrument's design
allows for multiple calibration scales, then the lower scale shall be
calibrated with a calibration gas that is no higher than 2,000 parts
per million above the concentration specified as a leak, and the
highest scale shall be calibrated with a calibration gas that is
approximately equal to 10,000 parts per million. If only one scale on
an instrument will be used during monitoring, the owner or operator
need not calibrate the scales that will not be used during that day's
monitoring.
(ii) A calibration gas other than methane in air may be used if the
instrument does not respond to methane or if the instrument does not
meet the performance criteria specified in paragraph (b)(2)(i) of this
section. In such cases, the calibration gas may be a mixture of one or
more of the compounds to be measured in air.
(5) Monitoring performance. Monitoring shall be performed when the
equipment is in regulated material service or is in use with any other
detectable material.
(6) Monitoring data. Monitoring data obtained prior to the
regulated source becoming subject to the referencing subpart that do
not meet the criteria specified in paragraphs (b)(1) through (5) of
this section may still be used to qualify initially for less frequent
monitoring under the provisions in Sec. 65.106(a)(2), (b)(3), or (b)(4)
for valves or Sec. 65.108(b)(3) for connectors, provided the departures
from the criteria or from the specified monitoring frequency of
Sec. 65.106(b)(3) or (4) are minor and do not significantly affect the
quality of the data. Examples of minor departures are monitoring at a
slightly different frequency (such as every 6 weeks instead of monthly
or quarterly), following the performance criteria of section 3.1.2(a)
of Method 21 of appendix A of 40 CFR part 60 instead of paragraph
(b)(2) of this section, or monitoring using a different leak definition
if the data would indicate the presence or absence of a leak at the
concentration specified in this subpart. Failure to use a calibrated
instrument is not considered a minor departure.
(c) Instrument monitoring readings and background adjustments. The
owner or operator may elect to adjust or not to adjust the instrument
readings for background. If an owner or operator elects not to adjust
instrument readings for background, the owner or operator shall monitor
the equipment according to the procedures specified in paragraphs
(b)(1) through (5) of this section. In such cases, all instrument
readings shall be compared directly to the applicable leak definition
for the monitored equipment to determine whether there is a leak or to
determine compliance with Sec. 65.111(b) (pressure relief devices) or
Sec. 65.112(f) (alternative compressor standard). If an owner or
operator elects to adjust instrument readings for background, the owner
or
[[Page 78319]]
operator shall monitor the equipment according to the following
procedures:
(1) The requirements of paragraphs (b)(1) through (5) of this
section shall apply.
(2) The background level shall be determined using the procedures
in Method 21 of appendix A of 40 CFR part 60.
(3) The instrument probe shall be traversed around all potential
leak interfaces as close to the interface as possible as described in
Method 21 of appendix A of 40 CFR part 60.
(4) The arithmetic difference between the maximum concentration
indicated by the instrument and the background level shall be compared
to the applicable leak definition for the monitored equipment to
determine whether there is a leak or to determine compliance with
Sec. 65.111(b) (pressure relief devices) or Sec. 65.112(f) (alternative
compressor standard).
(d) Sensory monitoring methods. Sensory monitoring consists of
visual, audible, olfactory, or any other detection method used to
determine a potential leak to the atmosphere.
(e) Leaking equipment identification and records. (1) When each
leak is detected, a weatherproof and readily visible identification
shall be attached to the leaking equipment.
(2) When each leak is detected, the information specified in
paragraphs (e)(2)(i) and (ii) of this section shall be recorded and
kept pursuant to Sec. 65.4(a), except the information for valves
complying with the 2-year monitoring period allowed under
Sec. 65.106(b)(3)(v), and connectors complying with the 8-year
monitoring period allowed under Sec. 65.108(b)(3)(iii) shall be kept 5
years beyond the date of the last use of the information to set a
monitoring period.
(i) The instrument, the equipment identification, and the
instrument operator's name, initials, or identification number if a
leak is detected or confirmed by instrument monitoring.
(ii) The date the leak was detected.
Sec. 65.105 Leak repair.
(a) Leak repair schedule. The owner or operator shall repair each
leak detected as soon as practical but not later than 15 calendar days
after it is detected except as provided in paragraph (d) or (e) of this
section. A first attempt at repair as defined in subpart A of this part
shall be made no later than 5 calendar days after the leak is detected.
First attempt at repair for pumps includes, but is not limited to,
tightening the packing gland nuts and/or ensuring that the seal flush
is operating at design pressure and temperature. First attempt at
repair for valves includes, but is not limited to, tightening the
bonnet bolts, and/or replacing the bonnet bolts, and/or tightening the
packing gland nuts, and/or injecting lubricant into the lubricated
packing.
(b) [Reserved]
(c) Leak identification removal. (1) Valves and connectors. The
leak identification on a valve in gas/vapor or light liquid service may
be removed after it has been monitored as specified in
Sec. 65.106(d)(2) and no leak has been detected during that monitoring.
The leak identification on a connector in gas/vapor or light liquid
service may be removed after it has been monitored as specified in
Sec. 65.108(b)(3)(iv) and no leak has been detected during that
monitoring.
(2) Other equipment. The identification that has been placed
pursuant to Sec. 65.104(e)(1) on equipment determined to have a leak,
except for a valve or for a connector that is subject to the provisions
of Sec. 65.108(b)(3)(iv), may be removed after it is repaired.
(d) Delay of repair. Delay of repair is allowed for any of the
conditions specified in paragraphs (d)(1) through (5) of this section.
The owner or operator shall maintain a record of the facts that explain
any delay of repairs and, where appropriate, why repair within 15 days
was technically infeasible without a process unit shutdown.
(1) Delay of repair of equipment for which leaks have been detected
is allowed if repair within 15 days after a leak is detected is
technically infeasible without a process unit shutdown. Repair of this
equipment shall occur as soon as practical, but no later than the end
of the next process unit shutdown, except as provided in paragraph
(d)(5) of this section.
(2) Delay of repair of equipment for which leaks have been detected
is allowed for equipment that is isolated from the process and that
does not remain in regulated material service.
(3) Delay of repair for valves, connectors, and agitators is also
allowed if the following provisions are met:
(i) The owner or operator determines that emissions of purged
material resulting from immediate repair would be greater than the
fugitive emissions likely to result from delay of repair; and
(ii) When repair procedures are effected, the purged material is
collected and routed to a process or fuel gas system or is collected
and destroyed or recovered in a control device complying with
Sec. 65.115.
(4) Delay of repair for pumps is also allowed if the provisions of
paragraphs (d)(4)(i) and (ii) of this section are met.
(i) Repair requires replacing the existing seal design with a new
system that the owner or operator has determined under the provisions
of Sec. 65.116(d) will provide better performance or one of the
following specifications are met:
(A) A dual mechanical seal system that meets the requirements of
Sec. 65.107(e)(1) will be installed;
(B) A pump that meets the requirements of Sec. 65.107(e)(2) will be
installed; or
(C) A system that routes emissions to a process or a fuel gas
system or a closed vent system and control device that meets the
requirements of Sec. 65.107(e)(3) will be installed.
(ii) Repair is completed as soon as practical but not later than 6
months after the leak was detected.
(5) Delay of repair beyond a process unit shutdown will be allowed
for a valve if valve assembly replacement is necessary during the
process unit shutdown, and valve assembly supplies have been depleted,
and valve assembly supplies had been sufficiently stocked before the
supplies were depleted. Delay of repair beyond the second process unit
shutdown will not be allowed unless the third process unit shutdown
occurs sooner than 6 months after the first process unit shutdown.
(e) Unsafe-to-repair: Connectors. Any connector that is designated
as described in Sec. 65.103(d) as an unsafe-to-repair connector is
exempt from the requirements of Sec. 65.108(d) and paragraph (a) of
this section if the provisions of Sec. 65.103(d) are met.
(f) Leak repair records. For each leak detected, the information
specified in paragraphs (f)(1) through (5) of this section shall be
recorded and kept pursuant to Sec. 65.4(a).
(1) The date of first attempt to repair the leak.
(2) The date of successful repair of the leak.

not repaired within 15 calendar days after discovery of the leak as
specified in the paragraphs (f)(4)(i) and (ii) of this section.
(i) The owner or operator may develop a written procedure that
identifies the conditions that justify a delay of repair. The written
procedures may be included as part of the startup/
[[Page 78320]]
shutdown/malfunction plan required by Sec. 65.6 for the source or may
be part of a separate document that is maintained at the plant site. In
such cases, reasons for delay of repair may be documented by citing the
relevant sections of the written procedure.
(ii) If delay of repair was caused by depletion of stocked parts,
there must be documentation that the spare parts were sufficiently
stocked onsite before depletion and the reason for depletion.
(5) Dates of process unit shutdowns that occur while the equipment
is unrepaired.
Sec. 65.106 Standards: Valves in gas/vapor service and in light liquid
service.

paragraph (e) of this section, the owner or operator shall monitor all
valves at the intervals specified in paragraphs (b)(3) and/or (b)(4) of
this section and shall comply with all other provisions of this
section.
(1) Monitoring method. The valves shall be monitored to detect
leaks by the method specified in Sec. 65.104(b) and (c).
(2) Instrument reading that defines a leak. The instrument reading
that defines a leak is 500 parts per million or greater.
(3) Monitoring frequency. The owner or operator shall monitor
valves for leaks at the intervals specified in paragraphs (b)(3)(i)
through (v) of this section and shall keep the record specified in
paragraph (b)(3)(vi) of this section.
(i) If at least the greater of two valves or 2 percent of the
valves in a process unit leak, as calculated according to paragraph (c)
of this section, the owner or operator shall monitor each valve once
per month.
(ii) At process units with less than the greater of two leaking
valves or 2 percent leaking valves, the owner or operator shall monitor
each valve once each quarter except as provided in paragraphs
(b)(3)(iii) through (v) of this section. Monitoring data generated
before the regulated source became subject to the referencing subpart
and meeting the criteria of either Sec. 65.104(b)(1) through (5) or
Sec. 65.104(b)(6) may be used to qualify initially for less frequent
monitoring under paragraphs (b)(3)(iii) through (v) of this section.
(iii) At process units with less than 1 percent leaking valves, the
owner or operator may elect to monitor each valve once every 2
quarters.
(iv) At process units with less than 0.5 percent leaking valves,

quarters.
(v) At process units with less than 0.25 percent leaking valves,
the owner or operator may elect to monitor each valve once every 2
years.
(vi) The owner or operator shall keep a record of the monitoring
schedule for each process unit.
(4) Valve subgrouping. For a process unit or a group of process
units to which this subpart applies, an owner or operator may choose to
subdivide the valves in the applicable process unit or group of process
units and apply the provisions of paragraph (b)(3) of this section to
each subgroup. If the owner or operator elects to subdivide the valves
in the applicable process unit or group of process units, then the
provisions of paragraphs (b)(4)(i) through (viii) of this section
apply.
(i) The overall performance of total valves in the applicable
process unit or group of process units to be subdivided shall be less
than 2 percent leaking valves, as detected according to paragraphs
(b)(1) and (2) of this section and as calculated according to
paragraphs (c)(1)(ii) and (c)(2) of this section.
(ii) The initial assignment or subsequent reassignment of valves to
subgroups shall be governed by the following provisions:
(A) The owner or operator shall determine which valves are assigned
to each subgroup. Valves with less than 1 year of monitoring data or
valves not monitored within the last 12 months must be placed initially
into the most frequently monitored subgroup until at least 1 year of
monitoring data have been obtained.
(B) Any valve or group of valves can be reassigned from a less
frequently monitored subgroup to a more frequently monitored subgroup
provided that the valves to be reassigned were monitored during the
most recent monitoring period for the less frequently monitored
subgroup. The monitoring results must be included with that less
frequently monitored subgroup's associated percent leaking valves
calculation for that monitoring event.
(C) Any valve or group of valves can be reassigned from a more
frequently monitored subgroup to a less frequently monitored subgroup
provided that the valves to be reassigned have not leaked for the
period of the less frequently monitored subgroup (for example, for the
last 12 months, if the valve or group of valves is to be reassigned to
a subgroup being monitored annually). Nonrepairable valves may not be
reassigned to a less frequently monitored subgroup.
(iii) The owner or operator shall determine every 6 months if the
overall performance of total valves in the applicable process unit or
group of process units is less than 2 percent leaking valves and so
indicate the performance in the next periodic report. If the overall
performance of total valves in the applicable process unit or group of
process units is 2 percent leaking valves or greater, the owner or
operator shall no longer subgroup and shall revert to the program
required in paragraphs (b)(1) through (3) of this section for that
applicable process unit or group of process units. An owner or operator
can again elect to comply with the valve subgrouping procedures of
paragraph (b)(4) of this section if future overall performance of total
valves in the process unit or group of process units is again less than
2 percent. The overall performance of total valves in the applicable
process unit or group of process units shall be calculated as a
weighted average of the percent leaking valves of each subgroup
according to Equation 106-1 of this section:
[GRAPHIC] [TIFF OMITTED] TR14DE00.005
Where:
%VLO = Overall performance of total valves in the applicable
process unit or group of process units.
%VLi = Percent leaking valves in subgroup i, most recent
value calculated according to the procedures in paragraphs (c)(1)(ii)
and (c)(2) of this section.
Vi = Number of valves in subgroup i.
n = Number of subgroups.
(iv) The owner or operator shall maintain the following records:
(A) Which valves are assigned to each subgroup;
(B) Monitoring results and calculations made for each subgroup for
each monitoring period;
(C) Which valves are reassigned, the last monitoring result prior
to reassignment, and when they were reassigned; and
(D) The results of the semiannual overall performance calculation
[[Page 78321]]
required in paragraph (b)(4)(iii) of this section.
(v) The owner or operator shall notify the Administrator no later
than 30 days prior to the beginning of the next monitoring period of
the decision to begin or end subgrouping valves. The notification shall
identify the participating process units and the number of valves
assigned to each subgroup, if applicable. The notification may be
included in a periodic report if the periodic report is submitted no
later than 30 days prior to the beginning of the next monitoring
period.
(vi) The owner or operator shall submit in the periodic reports the
following information:
(A) Total number of valves in each subgroup; and
(B) Results of the semiannual overall performance calculation
required by paragraph (b)(4)(iii) of this section.
(vii) To determine the monitoring frequency for each subgroup, the
calculation procedures of paragraph (c)(2) of this section shall be
used.
(viii) Except for the overall performance calculations required by
paragraphs (b)(4)(i) and (iii) of this section, each subgroup shall be
treated as if it were a separate process unit for the purposes of
applying the provisions of this section.
(c) Percent leaking valves calculation--(1) Calculation basis and
procedures. (i) The owner or operator shall decide no later than the
implementation date of this part or upon revision of an operating
permit whether to calculate percent leaking valves on a process unit or
group of process units basis. Once the owner or operator has decided,
all subsequent percentage calculations shall be made on the same basis,
and this shall be the basis used for comparison with the subgrouping
criteria specified in paragraph (b)(4)(i) of this section.
(ii) The percent leaking valves for each monitoring period for each
process unit or valve subgroup, as provided in paragraph (b)(4) of this
section, shall be calculated using Equation 106-2 of this section:
[GRAPHIC] [TIFF OMITTED] TR14DE00.020
Where:
%VL = Percent leaking valves.
VL = Number of valves found leaking, including those valves
found leaking pursuant to paragraphs (d)(2)(iii)(A) and (d)(2)(iii)(B)
of this section and excluding nonrepairable valves as provided in
paragraph (c)(3) of this section.
VT = The sum of the total number of valves monitored.
(2) Calculation for monitoring frequency. When determining
monitoring frequency for each process unit or valve subgroup subject to
monthly, quarterly, or semiannual monitoring frequencies, the percent
leaking valves shall be the arithmetic average of the percent leaking
valves from the last two monitoring periods. When determining
monitoring frequency for each process unit or valve subgroup subject to
annual or biennial (once every 2 years) monitoring frequencies, the
percent leaking valves shall be the arithmetic average of the percent
leaking valves from the last three monitoring periods.
(3) Nonrepairable valves. (i) Nonrepairable valves shall be
included in the calculation of percent leaking valves the first time
the valve is identified as leaking and nonrepairable and as required to
comply with paragraph (c)(3)(ii) of this section. Otherwise, a number
of nonrepairable valves (identified and included in the percent leaking
valves calculation in a previous period) up to a maximum of 1 percent
of the total number of valves in regulated material service at a
process unit may be excluded from calculation of percent leaking valves
for subsequent monitoring periods.
(ii) If the number of nonrepairable valves exceeds 1 percent of the
total number of valves in regulated material service at a process unit,
the number of nonrepairable valves exceeding 1 percent of the total
number of valves in regulated material service shall be included in the
calculation of percent leaking valves.
(d) Leak repair. (1) If a leak is determined pursuant to paragraph
(b), (e)(1), or (e)(2) of this section, then the leak shall be repaired
using the procedures in Sec. 65.105, as applicable.
(2) After a leak determined under paragraph (b) or (e)(2) of this
section has been repaired, the valve shall be monitored at least once
within the first 3 months after its repair. The monitoring required by
paragraph (d) of this section is in addition to the monitoring required
to satisfy the definition of repair.
(i) The monitoring shall be conducted as specified in
Sec. 65.104(b) and (c), as appropriate, to determine whether the valve
has resumed leaking.
(ii) Periodic monitoring required by paragraph (b) of this section
may be used to satisfy the requirements of paragraph (d) of this
section if the timing of the monitoring period coincides with the time
specified in paragraph (d) of this section. Alternatively, other
monitoring may be performed to satisfy the requirements of paragraph
(d) of this section regardless of whether the timing of the monitoring
period for periodic monitoring coincides with the time specified in
paragraph (d) of this section.
(iii) If a leak is detected by monitoring that is conducted under
paragraph (d)(2) of this section, the owner or operator shall comply
with the following provisions to determine whether that valve must be
counted as a leaking valve for purposes of paragraph (c)(1)(ii) of this
section:
(A) If the owner or operator elected to use periodic monitoring
required by paragraph (b) of this section to satisfy the requirements
of paragraph (d)(2) of this section, then the valve shall be counted as
a leaking valve.
(B) If the owner or operator elected to use other monitoring, prior
to the periodic monitoring required by paragraph (b) of this section,
to satisfy the requirements of paragraph (d)(2) of this section, then
the valve shall be counted as a leaking valve unless it is repaired and
shown by periodic monitoring not to be leaking.
(e) Special provisions for valves--(1) Unsafe-to-monitor valves.
Any valve that is designated as described in Sec. 65.103(c)(1) as an

emission performance. The analysis shall determine if specific trouble
areas can be identified on the basis of service, operating conditions
or maintenance practices, equipment design, or other process-specific
factors.
(ii) The analysis shall also be used to determine if there are
superior performing pump or pump seal technologies that are applicable
to the service(s), operating conditions, or pump or pump seal designs
associated with poorer than average emission performance. A superior
performing pump or pump seal technology is one with a leak frequency of
less than 10 percent for specific applications in the process unit or
plant site. A candidate superior performing pump or pump seal
technology is one demonstrated or reported in the available literature
or through a group study as having low emission performance and as
being capable of achieving less than 10 percent leaking pumps in the
process unit (or plant site).
(iii) The analysis shall include consideration of the following
information:
(A) The data obtained from the inspections of pumps and pump seals
removed from the process unit due to leaks;

company, or a group of process units.
(v) The first analysis of the data shall be completed no later than
18 months after the start of the quality improvement program. The first
analysis shall be performed using data collected for a minimum of 6
months. An analysis of the data shall be done each year the process
unit is in the quality improvement program.
(6) Trial evaluation program. A trial evaluation program shall be
conducted at each plant site for which the data analysis does not
identify use of superior performing pump seal technology or pumps that
can be applied to the areas identified as having poorer than average
performance except as provided in paragraph (d)(6)(v) of this section.
The trial program shall be used to evaluate the feasibility of using in
the process unit (or plant site) the pump designs or seal technologies,
and operating and maintenance practices that have been identified by
others as having low emission performance.
(i) The trial evaluation program shall include on-line trials of
pump seal technologies or pump designs and operating and maintenance
practices that have been identified in the available literature or in
analysis by others as having the ability to perform with leak rates
below 10 percent in similar services, as having low probability of
failure, or as having no external actuating mechanism in contact with
the process fluid. If any of the candidate superior performing pump
seal technologies or pumps is not included in the performance trials,
the reasons for rejecting specific technologies from consideration
shall be documented as required in paragraph (e)(3)(ii) of this
section.
(ii) The number of pump seal technologies or pumps in the trial
evaluation program shall be the lesser of 1 percent or two pumps for
programs involving single process units, and the lesser of 1 percent or
five pumps for programs involving a plant site or groups of process
units. The minimum number of pumps or pump seal technologies in a trial
program shall be one.
(iii) The trial evaluation program shall specify and include
documentation of the following information:

be evaluated; and
(D) Conclusions regarding the emission performance and the
appropriate operating conditions and services for the trial pump seal
technologies or pumps.
(iv) The performance trials shall initially be conducted at least
for a 6-month period beginning not later than 18 months after the start
of the quality improvement program. No later than 24 months after the
start of the quality improvement program, the owner or operator shall
have identified pump seal technologies or pump designs that, combined
with appropriate process, operating, and maintenance practices, operate
with low emission performance for specific applications in the process
unit. The owner or operator shall continue to conduct performance
trials as long as no superior performing design or technology has been
identified, except as provided in paragraph (d)(6)(vi) of this section.
The initial list of superior emission performance pump designs or pump
seal technologies shall be amended in the future, as appropriate, as
additional information and experience are obtained.
(v) Any plant site with fewer than 400 valves and owned by a
corporation with fewer than 100 employees shall be exempt from trial
evaluations of pump seals or pump designs. Plant sites exempt from the
trial evaluations of pumps shall begin the pump seal or pump
replacement program at the start of the fourth year of the quality
improvement program.
(vi) An owner or operator who has conducted performance trials on
all alternative superior emission performance technologies suitable for
the required applications in the process unit may stop conducting
performance trials provided that a superior performing design or
technology has been demonstrated, or there are no technically feasible
alternative superior technologies remaining. The owner or operator
shall prepare an engineering evaluation documenting the physical,
chemical, or engineering basis for the judgment that the superior
emission performance technology is technically infeasible or
demonstrating that it would not reduce emissions.
(7) Quality assurance program. Each owner or operator shall prepare
and implement a pump quality assurance program that details purchasing
specifications and maintenance procedures for all pumps and pump seals
in the process unit. The quality assurance program may establish any
number of categories, or classes, of pumps as needed to distinguish
among operating conditions and services associated with poorer than
average emission performance, as well as those associated with better
than average emission performance. The quality assurance program shall
be developed considering the findings of the data analysis required
under paragraph (d)(5) of this section, if applicable; the findings of
the trial evaluation required in paragraph (d)(6) of this section; and
the operating conditions in the process unit. The quality assurance
program shall be updated each year as long as the process unit has the
greater of either 10 percent or more leaking pumps or has three leaking
pumps.
(i) The quality assurance program shall meet the following

procedures shall include provisions to ensure that rebuilt or
refurbished pumps and pump seals will meet the design specifications
for the pump category and will operate so that emissions are minimized.
(ii) The quality assurance program shall be established no later
than the start of the third year of the quality improvement program for
plant sites with 400 or more valves or 100 or more employees, and no
later than the start of the fourth year of the quality improvement
program for plant sites with less than 400 valves and less than 100
employees.
(8) Pump or pump seal replacement. Beginning at the start of the
third year of the quality improvement program for plant sites with 400
or more valves or 100 or more employees and at the start of the fourth
year of the quality improvement program for plant sites with less than
400 valves and less than 100 employees, the owner or operator shall
replace as described in paragraphs (d)(8)(i) and (ii) of this section
the pumps or pump seals that are not superior emission performance
technology with pumps or pump seals that have been identified as
superior emission performance technology and that comply with the
quality assurance standards for the pump category. Superior emission
performance technology is that category or design of pumps or pump
seals with emission performance that, when combined with appropriate
process, operating, and maintenance practices, will result in less than
10 percent leaking pumps for specific applications in the process unit
or plant site. Superior emission performance technology includes
material or design changes to the existing pump, pump seal, seal
support system, installation of multiple mechanical seals or
equivalent, or pump replacement.
(i) Pumps or pump seals shall be replaced at the rate of 20 percent
per year based on the total number of pumps in light liquid service.
The calculated value shall be rounded to the nearest nonzero integer
value. The minimum number of pumps or pump seals shall be one. Pump
replacement shall continue until all pumps subject to the requirements
of Sec. 65.107 are pumps determined to be superior performance
technology.
(ii) The owner or operator may delay replacement of pump seals or
pumps with superior technology until the next planned process unit
shutdown provided the number of pump seals and pumps replaced is
equivalent to the 20 percent or greater annual replacement rate.
(iii) The pumps shall be maintained as specified in the quality
assurance program.
(e) QIP recordkeeping. In addition to the records required by
paragraph (d)(2) of this section, the owner or operator shall maintain

or operator of a batch process that operates in regulated material
service during the calendar year may comply with one of the standards
specified in paragraphs (b) and (c) of this section, or the owner or
operator may petition for approval of an alternative standard under the
provisions of Sec. 65.102(b). The alternative standards of this section
provide the options of pressure testing or monitoring the equipment for
leaks. The owner or operator may switch among the alternatives provided
the change is documented as specified in paragraph (b)(7) of this
section.
(b) Pressure testing of the batch equipment. The following
requirements shall be met if an owner or operator elects to use
pressure testing of batch product-process equipment to demonstrate
compliance with this subpart:

process equipment train shall be pressure-tested for leaks before
regulated material is first fed to the equipment and the equipment is
placed in regulated material service.
(i) When the batch product-process equipment train is reconfigured
to produce a different product, pressure testing is required only for
the new or disturbed equipment.
(ii) Each batch product-process that operates in regulated material
service during a calendar year shall be pressure-tested at least once
during that calendar year.
(iii) Pressure testing is not required for routine seal breaks,
such as changing hoses or filters, that are not part of the
reconfiguration to produce a different product or intermediate.
(2) Testing procedures. The batch product-process equipment shall
be tested either using the procedures specified in paragraph (b)(5) of
this section for pressure vacuum loss or with a liquid using the
procedures specified in paragraph (b)(6) of this section.
(3) Leak detection. (i) For pressure or vacuum tests using a gas, a
leak is detected if the rate of change in pressure is greater than 6.9
kilopascals (1 pound per square inch gauge) in 1 hour or if there is
visible, audible, or olfactory evidence of fluid loss.
(ii) For pressure tests using a liquid, a leak is detected if there
are indications of liquids dripping or if there is other evidence of
fluid loss.
(4) Leak repair. (i) If a leak is detected, it shall be repaired
and the batch product-process equipment shall be retested before
startup of the process.
(ii) If a batch product-process fails the retest (the second of two
consecutive pressure tests), it shall be repaired as soon as practical
but not later than 30 calendar days after the second pressure test,
except as specified in paragraph (e) of this section.
(5) Gas pressure test procedure for pressure or vacuum loss. The
following procedures shall be used to pressure test batch product-
process equipment for pressure or vacuum loss to demonstrate compliance
with the requirements of paragraph (b)(3)(i) of this section:
(i) The batch product-process equipment train shall be pressurized
with a gas to a pressure less than the set pressure of any safety
relief devices or valves or to a pressure slightly above the operating
pressure of the equipment, or alternatively the equipment shall be
placed under a vacuum.
(ii) Once the test pressure is obtained, the gas source or vacuum
source shall be shut off.
(iii) The test shall continue for not less than 15 minutes unless
it can be determined in a shorter period of time that the allowable
rate of pressure drop or of pressure rise was exceeded. The pressure in
the batch product-process equipment shall be measured after the gas or
vacuum source is shut off and at the end of the test period. The rate
of change in pressure in the batch product-process equipment shall be
calculated using Equation 117-1 of this section:
[GRAPHIC] [TIFF OMITTED] TR14DE00.007
Where:
(P/t) = Change in pressure, pounds per square inch gauge/hr.
Pf = Final pressure, pounds per square inch gauge.
Pi = Initial pressure, pounds per square inch gauge.
tf - ti = Elapsed time, hours.
(iv) The pressure shall be measured using a pressure measurement
device (gauge, manometer, or equivalent) that has a precision of
2.5 millimeters mercury (0.10 inch of mercury) in the range
of test pressure and is capable of measuring pressures up to the relief
set pressure of the pressure relief device. If such a pressure
measurement device is not reasonably available, the owner or operator
shall use a pressure measurement device with a precision of at least
10 percent of the test pressure
[[Page 78330]]
of the equipment and shall extend the duration of the test for the time
necessary to detect a pressure loss or rise that equals a rate of 1
pound per square inch gauge per hour (7 kilopascals per hour).
(v) An alternative procedure may be used for leak testing the
equipment if the owner or operator demonstrates the alternative
procedure is capable of detecting a pressure loss or rise.
(6) Pressure test procedure using test liquid. The following
procedures shall be used to pressure test batch product-process
equipment using a liquid to demonstrate compliance with the
requirements of paragraph (b)(3)(ii) of this section:

equipment train shall be filled with the test liquid (for example,
water, alcohol) until normal operating pressure is obtained. Once the
equipment is filled, the liquid source shall be shut off.
(ii) The test shall be conducted for a period of at least 60
minutes unless it can be determined in a shorter period of time that
the test is a failure.
(iii) Each seal in the equipment being tested shall be inspected
for indications of liquid dripping or other indications of fluid loss.
If there are any indications of liquids dripping or of fluid loss, a
leak is detected.
(iv) An alternative procedure may be used for leak testing the
equipment if the owner or operator demonstrates the alternative
procedure is capable of detecting losses of fluid.
(7) Pressure testing recordkeeping. The owner or operator of a
batch product-process who elects to pressure test the batch product-
process equipment train to demonstrate compliance with this subpart
shall maintain records of the information specified in paragraphs

during the calendar year. It is not necessary to identify individual
items of equipment in a batch product-process equipment train.
(ii) Physical tagging of the equipment to identify that it is in
regulated material service and subject to the provisions of this
subpart is not required. Equipment in a batch product-process subject
to the provisions of this subpart may be identified on a plant site
plan, in log entries, or by other appropriate methods.
(iii) The dates of each pressure test required in paragraph (b) of
this section, the test pressure, and the pressure drop observed during
the test.
(iv) Records of any visible, audible, or olfactory evidence of

appendix
[[Page 78335]]
A of 40 CFR part 60 except as specified in this section.
(ii) Except as provided in paragraph (c)(1)(iii) of this section,
the detection instrument shall meet the performance criteria of Method
21 of appendix A of 40 CFR part 60, except the instrument response
factor criteria in section 3.1.2(a) of Method 21 shall be for the
representative composition of the process fluid not each individual
organic compound in the stream. For process streams that contain
nitrogen, air, water, or other inerts that are not organic hazardous
air pollutants or volatile organic compounds, the response factor shall
be determined on an inert-free basis. The response factor may be
determined at any concentration for which the monitoring for leaks will
be conducted. Maintain the record specified by Sec. 65.163(a)(5).
(iii) If no instrument is available at the plant site that will
meet the performance criteria specified in paragraph (c)(1)(ii) of this
section, the instrument readings may be adjusted by multiplying by the
representative response factor of the process fluid calculated on an
inert-free basis as described in paragraph (c)(1)(ii) of this section.
(iv) The detection instrument shall be calibrated before use on
each day of its use by the procedures specified in Method 21 of
appendix A of 40 CFR part 60.
(v) Calibration gases shall be as specified in the following:
(A) Zero air (less than 10 parts per million hydrocarbon in air).
(B) Mixtures of methane in air at a concentration less than 10,000
parts per million. A calibration gas other than methane in air may be
used if the instrument does not respond to methane or if the instrument
does not meet the performance criteria specified in paragraph
(c)(1)(ii) of this section. In such cases, the calibration gas may be a
mixture of one or more of the compounds to be measured in air.
(C) If the detection instrument's design allows for multiple
calibration scales, then the lower scale shall be calibrated with a
calibration gas that is no higher than 2,500 parts per million.
(vi) An owner or operator may elect to adjust or not adjust
instrument readings for background. If an owner or operator elects not
to adjust readings for background, all such instrument readings shall
be compared directly to 500 parts per million to determine whether
there is a leak. If an owner or operator elects to adjust instrument
readings for background, the owner or operator shall measure background
concentration using the procedures in this section. The owner or
operator shall subtract the background reading from the maximum
concentration indicated by the instrument.
(vii) If the owner or operator elects to adjust for background, the
arithmetic difference between the maximum concentration indicated by
the instrument and the background level shall be compared with 500
parts per million for determining whether there is a leak.
(2) The instrument probe shall be traversed around all potential
leak interfaces as close to the interface as possible as described in

follow either of the following procedures:
(i) The owner or operator shall eliminate the indications of the
leak.
(ii) The owner or operator shall monitor the equipment according to
the procedures in paragraph (c) of this section.
(2) Leaks as indicated by an instrument reading greater than 500
parts per million by volume above background shall be repaired as soon
as practical except as provided in paragraph (d)(3) of this section.
Records shall be generated as specified in Sec. 65.163(a)(3) when a
leak is detected.
(i) A first attempt at repair shall be made no later than 5
calendar days after the leak is detected.
(ii) Except as provided in paragraph (d)(3) of this section,
repairs shall be completed no later than 15 calendar days after the
leak is detected or at the beginning of the next introduction of vapors
to the system, whichever is later.
(3) Delay of repair of a closed vent system for which leaks have
been detected is allowed if repair within 15 days after a leak is
detected is technically infeasible without a closed vent system
shutdown, as defined in Sec. 65.2, or if the owner or operator
determines that emissions resulting from immediate repair would be
greater than the emissions likely to result from delay of repair.
Repair of such equipment shall be completed as soon as practical, but

within 180 days if required by paragraph (b)(1) of this section. The
performance test report shall be submitted to the Administrator within
60 days of completing the determination as provided in
Sec. 65.164(b)(2). If an owner or operator elects to use a control
device to replace an existing recovery device that is used on a Group
2A process vent, the owner or operator shall comply with the applicable
provisions of Secs. 65.63(e) and 65.67(b) and submit the notification
specified in Sec. 65.167(a).
(c) Other control device monitoring requirements. (1) Unless
previously submitted and approved under the referencing subpart, if an
owner or operator uses a control device other than those listed in this
subpart, the owner or operator shall submit a description of planned
monitoring, reporting, and recordkeeping procedures as required under
Sec. 65.162(e). The Administrator will approve, deny, or modify based
on the reasonableness of the proposed monitoring, reporting, and
recordkeeping requirements as part of the review of the submission or
permit application or by other appropriate means.
(2) The owner or operator shall establish a range for monitored
parameters that indicates proper operation of the control device. To
establish the range, the information required in Sec. 65.165(c) shall
be submitted in the Initial Compliance Status Report or the operating
permit application or amendment. The range may be based upon a prior
performance test meeting the specifications in Sec. 65.157(b)(1) or
upon existing ranges or limits established under a referencing subpart.
Sec. 65.156 General monitoring requirements for control and recovery
devices.
(a) General monitoring requirement applicability. (1) This section
applies to the owner or operator of a regulated source required to
monitor under this subpart.
(2) Flares subject to Sec. 65.147(c) are not subject to the
requirements of this section.
(3) Flow indicators are not subject to the requirements of this
section.
(b) Conduct of monitoring. (1) Monitoring shall be conducted as set
forth in this section and in the relevant sections of this subpart
unless either of the following provisions applies:
(i) The Administrator specifies or approves the use of minor or
intermediate changes in the specified monitoring requirements or
procedures as provided in Sec. 65.7(b), (c), and (d); or
(ii) The Administrator specifies or approves the use of major
changes in the specified monitoring requirements or procedures as
provided in Sec. 65.7(b), (c), and (d).
(2) When one CPMS is used as a backup to another CPMS, the owner or
operator shall report the results from the CPMS used to meet the
monitoring requirements of this subpart. If both such CPMS 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 CPMS for the relevant compliance period.
(c) Operation and maintenance of continuous parameter monitoring
systems. (1) All monitoring equipment shall be installed, calibrated,
maintained, and operated according to manufacturers specifications or
other written procedures that provide adequate assurance that the
equipment would reasonably be expected to monitor accurately.
(2) The owner or operator of a regulated source shall maintain and
operate each CPMS as specified in this section or in a relevant subpart
and in a manner consistent with good air pollution control practices.
(i) The owner or operator of a regulated source shall ensure the
immediate repair or replacement of CPMS parts to correct ``routine'' or
otherwise predictable CPMS malfunctions. The necessary parts for
routine repairs of the affected equipment shall be readily available.
(ii) Except for Group 2A process vents, if the startup, shutdown,
and malfunction plan is followed during a CPMS startup, shutdown, or
malfunction and the CPMS is repaired immediately, this action shall be
reported in the semiannual startup, shutdown, and malfunction report
required under Sec. 65.6(c).
(iii) The Administrator's determination of whether acceptable
[[Page 78344]]
operation and maintenance procedures are being used for the CPMS will
be based on information that may include, but is not limited to, review
of operation and maintenance procedures, operation and maintenance
records, manufacturer's recommendations and specifications, and
inspection of the CPMS.
(3) All CPMS shall be installed and operational, and the data
verified as specified in this subpart either prior to or in conjunction
with conducting performance tests. 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 or other written procedures that provide
adequate assurance that the equipment would reasonably be expected to
monitor accurately.
(4) All CPMS shall be installed such that representative
measurements of parameters from the regulated source are obtained.
(5) In accordance with Sec. 65.3(a)(3), except for system
breakdowns, repairs, maintenance periods, instrument adjustments or
checks to maintain precision and accuracy, calibration checks, and zero
and span adjustments, all CPMS shall be in continuous operation when
emissions are being routed to the monitored device.
(d) Except for Group 2A process vents, the parameter monitoring
data shall be used to determine compliance with the required operating
conditions for the monitored control devices. For each excursion,
except for excused excursions and the excursions described in paragraph
(d)(3) of this section, the owner or operator shall be deemed to have
failed to have applied the control in a manner that achieves the
required operating conditions.
(1) An excursion means any of the three cases listed in paragraphs
(d)(1)(i) through (iii) of this section. For a control device where
multiple parameters are monitored, if one or more of the parameters
meets the excursion criteria in paragraph (d)(1)(i), (ii), or (iii) of
this section, this is considered a single excursion for the day for the
control device.
(i) When the daily average value of one or more monitored
parameters is outside the permitted range.
(ii) When the period of control or recovery device operation is 4
hours or greater in an operating day, and monitoring data are
insufficient to constitute a valid hour of data for at least 75 percent
of the operating hours.
(iii) When the period of control or recovery device operation is
less than 4 hours in an operating day, and more than 1 hour during the
period of operation does not constitute a valid hour of data due to
insufficient monitoring data.
(iv) Monitoring data are insufficient to constitute a valid hour of
data as used in paragraphs (d)(1)(ii) and (iii) of this section, if
measured values are unavailable for any of the 15-minute periods within
the hour. For data compression systems approved under
Sec. 65.162(d)(4), monitoring data are insufficient to calculate a
valid hour of data if there are less than four data values recorded
during the hour.
(2) One excused excursion for each control device or recovery
device for each semiannual period is allowed.
(3) The following excursions are not violations and do not count as
excused excursions:
(i) Excursions which occur during periods of startup, shutdown, and
malfunction, when the source is being operated during such periods in
accordance with its startup, shutdown, and malfunction plan as required
by Sec. 65.6.
(ii) Excursions which occur due to failure to collect a valid hour
of data during periods of startup, shutdown, and malfunction, when the
source is being operated during such periods in accordance with its
startup, shutdown, and malfunction plan as required by Sec. 65.6.
(iii) Excursions which occur during periods of nonoperation of the
regulated source or portion thereof, resulting in cessation of the
emissions to which monitoring applies.
(4) Nothing in paragraph (d) of this section shall be construed to
allow or excuse a monitoring parameter excursion caused by any activity
that violates other applicable provisions of this part.
(5) Paragraph (d) of this section applies to emission points and
control devices for which continuous monitoring is required by this
subpart, and to alternatives to continuous monitoring systems such as
provided in Sec. 65.162(d)(3) and (d)(4). Paragraph (d)(3) of this
section also applies to emission points and control devices which are
not subject to continuous monitoring requirements, such as inspections
of the closed vent system.
(e) Alternative monitoring parameter. An owner or operator may
request approval to monitor control, recovery, halogen scrubber, or
halogen reduction device operating parameters other than those
specified in this subpart by following the procedures specified in
Sec. 65.162(e).
Sec. 65.157 Performance test and flare compliance determination
requirements.
(a) Performance tests and flare compliance determinations. Where
Secs. 65.145 through 65.155 require, or the owner or operator elects to
conduct, a performance test of a nonflare control device or a halogen
reduction device, or a compliance determination for a flare, the
requirements of paragraphs (b) through (d) of this section apply.
(b) Prior test results and waivers. Initial performance tests and
initial flare compliance determinations are required only as specified
in this subpart.
(1) Unless requested by the Administrator, an owner or operator is
not required to conduct a performance test or flare compliance
determination under this subpart if a prior performance test or
compliance determination was conducted using the same methods specified
in Sec. 65.158, and either no process changes have been made since the
test or the owner or operator can demonstrate to the Administrator's
satisfaction that the results of the performance test, with or without
adjustments, reliably demonstrate compliance despite process changes.
(2) Individual performance tests and flare compliance
determinations may be waived upon written application to the
Administrator per Sec. 65.164(b)(3) 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 under 40 CFR part 63, or a waiver of compliance under 40 CFR
part 61, or the owner or operator has requested an extension of
compliance under 40 CFR part 63, or a waiver of compliance under 40 CFR
part 61, and the Administrator is still considering that request.
(3) 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 notification is given to the owner
or operator of the source.
(c) Performance tests and flare compliance determinations schedule.
(1) Unless a waiver of performance testing or flare compliance
determination is obtained under this section or the conditions of
another subpart of this part, the owner or operator shall perform such
tests specified in the following:
(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 of that standard; or
[[Page 78345]]
(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 a
referencing subpart for an existing source or within 180 days after
startup of an existing source if the source begins operation after the
effective date of the relevant 40 CFR part 63 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 or a waiver of compliance for an existing
source that obtains an extension of compliance under 40 CFR 63.6(i) or
a waiver of compliance under 40 CFR 61.11; 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) of the Act (see 40 CFR
63.6(b)(4)); or
(vii) When a promulgated emission standard under 40 CFR part 63 is
more stringent than the standard that was proposed (see 40 CFR
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 initially with either the proposed or the
promulgated standard. If the owner or operator chooses to comply with
the proposed standard initially, the owner or operator shall conduct a
second performance test within 3 years and 180 days after the effective
date of the standard, or after startup of the source, whichever is
later, to demonstrate compliance with the promulgated standard.
(2) The Administrator may require an owner or operator to conduct
performance tests and compliance determinations at the regulated source
at any time when the action is authorized by section 114 of the Act.
(d) Performance testing facilities. If required to do performance
testing, the owner or operator of each new regulated source and, at the
request of the Administrator, the owner or operator of each existing
regulated source, shall provide performance testing facilities as
specified in the following:
(1) Sampling ports adequate for test methods applicable to such
source. This includes, as applicable, the following requirements:
(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.
Sec. 65.158 Performance test procedures for control devices.
(a) General procedures. Where Secs. 65.145 through 65.155 require,
or the owner or operator elects to conduct, a performance test of a
control device or a halogen reduction device, an owner or operator
shall comply with the requirements of (a)(1) through (3) of this
section, as applicable.
(1) Performance tests shall be conducted at maximum representative
operating conditions for the process unless the Administrator specifies
or approves alternate operating conditions. During the performance
test, an owner or operator may operate the control or halogen reduction
device at maximum or minimum representative operating conditions for
monitored control or halogen reduction device parameters, whichever
results in lower emission reduction. Operations during periods of
startup, shutdown, and malfunction shall not constitute representative
conditions for the purpose of a performance test.
(2) Performance tests shall be conducted and data shall be reduced
in accordance with the test methods and procedures set forth in this
subpart, in each relevant standard, and, if required, in applicable
appendices of 40 CFR parts 51, 60, 61, and 63 unless the Administrator
allows revisions to the test methods as specified in one or more of the
following five paragraphs:
(i) The Administrator specifies or approves, in specific cases, the
use of a test method with minor or intermediate changes in methodology;
or
(ii) The Administrator approves the use of a major change to a test
method, the results of which the Administrator has determined to be
adequate for indicating whether a specific regulated source is in
compliance; or
(iii) Intermediate and major changes to a test method shall be
validated using the applicable procedures of Method 301 of appendix A
of 40 CFR part 63; or
(iv) The Administrator waives the requirement for the performance
test as provided in Sec. 65.157(b)(2) because the owner or operator of
a regulated source has demonstrated by other means to the
Administrator's satisfaction that the regulated source is in compliance
with the relevant standard; or
(v) The Administrator approves the use of an equivalent method.
(3) Each performance test shall consist of three separate runs
using the applicable test method. Except as provided in paragraphs
(a)(3)(i) and (ii) of this section, each run shall be conducted for at
least 1 hour and under the conditions specified in this section. For
the purpose of determining compliance with an applicable standard, the
arithmetic mean of results of the three runs shall apply. In the event
that a sample is accidentally lost or conditions occur in which one of
the three runs must be discontinued because of forced shutdown, failure
of an irreplaceable portion of the sample train, extreme meteorological
conditions, or other circumstances beyond the owner or operator's
control, compliance may, upon the Administrator's approval, be
determined using the arithmetic mean of the results of the two other
runs.
(i) For control devices that are used to control emissions from
high-throughput transfer racks, and that are capable of continuous
vapor processing but do not handle continuous emissions or emissions
from high-throughput transfer racks that load simultaneously from
multiple loading arms, each run shall represent at least one complete
tank truck or tank car loading period during which regulated materials
are loaded, and samples shall be collected using integrated sampling or
grab samples taken at least four times per hour at approximately equal
intervals of time, such as 15-minute intervals.
(ii) For intermittent vapor processing systems used for controlling
high-throughput transfer rack emissions that
[[Page 78346]]
do not handle continuous emissions or multiple loading arms of a high-
throughput transfer rack that load simultaneously, each run shall
represent at least one complete control device cycle, and samples shall
be collected using integrated sampling or grab samples taken at least
four times per hour at approximately equal intervals of time, such as
15-minute intervals.
(b) Test methods. Where Secs. 65.145 through 65.155 require, or the
owner or operator elects to conduct, a performance test of a control
device or a halogen reduction device, an owner or operator shall
conduct that performance test using the procedures in paragraphs (b)(1)
through (4) of this section, as applicable. The regulated material
concentration and percent reduction may be measured as either total
regulated material or as TOC (minus methane and ethane) according to
the procedures specified.
(1) Method 1 or 1A of appendix A of 40 CFR part 60 as appropriate,
shall be used for selection of the sampling sites.
(i) For determination of compliance with a percent reduction
requirement of total regulated material or TOC, sampling sites shall be
located at the inlet of the control device as specified in the
following and at the outlet of the control device:
(A) For process vents, the control device inlet sampling site shall
be located after the final product recovery device.
(B) If a vent stream is introduced with the combustion air or as a
secondary fuel into a boiler or process heater with a design capacity
less than 44 megawatts (150 million British thermal units per hour),
selection of the location of the inlet sampling sites shall ensure the
measurement of total regulated material or TOC (minus methane and
ethane) concentrations, as applicable, in all vent streams and primary
and secondary fuels introduced into the boiler or process heater.
(ii) For determination of compliance with the 20 parts per million
by volume total regulated material or TOC limit in Sec. 65.63(a)(2),
Sec. 65.83(a)(1), and 40 CFR 60.562-1(a)(1)(i)(A), the sampling site
shall be located at the outlet of the control device.
(2) The gas volumetric flow rate shall be determined using Method
2, 2A, 2C, or 2D of appendix A of 40 CFR part 60, as appropriate.
(3) To determine compliance with the 20 parts per million by volume
total regulated material or TOC (minus methane and ethane) limit, the
owner or operator shall use Method 18 of appendix A of 40 CFR part 60
to measure either TOC minus methane and ethane or total regulated
material, as applicable. Alternatively, any other method or data that
have been validated according to the applicable procedures in Method
301 of appendix A of 40 CFR part 63 may be used. Method 25A may be used
for transfer racks as detailed in paragraph (b)(3)(iv) of this section.
The procedures specified in paragraphs (b)(3)(i) through (iv) of this
section shall be used to calculate parts per million by volume
concentration, corrected to 3 percent oxygen.
(i) Except as provided in paragraphs (a)(3)(i) and (ii) of this
section, the minimum sampling time for each run shall be 1 hour in
which either an integrated sample or a minimum of four grab samples
shall be taken. If grab sampling is used, then the samples shall be
taken at approximately equal intervals in time, such as 15 minute
intervals during the run.

part 63, subpart F, shall be used.
(iii) The concentration of TOC or total regulated material, as
applicable, shall be corrected to 3 percent oxygen if a combustion
device is the control device.
(A) The emission rate correction factor (or excess air) integrated
sampling and analysis procedures of Method 3B of appendix A of 40 CFR
part 60 shall be used to determine the oxygen concentration. The
sampling site shall be the same as that of the regulated material or
organic compound samples, and the samples shall be taken during the
same time that the regulated material or organic compound samples are
taken.
(B) The concentration corrected to 3 percent oxygen (Cc)
shall be computed using Equation 158-2 of this section:
[GRAPHIC] [TIFF OMITTED] TR14DE00.013
Where:

(iv) Method 25A of appendix A of 40 CFR part 60 may be used for the
purpose of determining compliance with the 20 parts per million by
volume limit specified in Sec. 65.83(a)(1) for transfer racks. If
Method 25A of appendix A of 40 CFR part 60 is used, the following
procedures shall be used to calculate the concentration of organic
compounds (CTOC):
(A) The principal organic HAP in the vent stream shall be used as
the calibration gas.
(B) The span value for Method 25A of appendix A of 40 CFR part 60
shall be between 1.5 and 2.5 times the concentration being measured.
(C) Use of Method 25A of appendix A of 40 CFR part 60 is acceptable
if the response from the high-level calibration gas is at least 20
times the standard deviation of the response from the zero
[[Page 78347]]
calibration gas when the instrument is zeroed on the most sensitive
scale.
(D) The concentration of TOC shall be corrected to 3 percent oxygen
using the procedures and equation in paragraph (b)(3)(iii) of this
section.
(4) To determine compliance with a percent reduction requirement,
the owner or operator shall use Method 18 of appendix A of 40 CFR part
60; alternatively, any other method or data that have been validated
according to the applicable procedures in Method 301 of appendix A of
40 CFR part 63 may be used. Method 25A of appendix A of 40 CFR part 60
may be used for transfer racks as detailed in paragraph (b)(4)(v) of
this section. Procedures specified in paragraphs (b)(4)(i) through (v)
of this section shall be used to calculate percent reduction
efficiency.
(i) Except as provided in paragraphs (a)(3)(i) and (ii) of this
section, the minimum sampling time for each run shall be 1 hour in
which either an integrated sample or a minimum of four grab samples
shall be taken. If grab sampling is used, then the samples shall be

section.
(C) Where the mass rate of total regulated material is being
calculated, only the species comprising the regulated material shall be
summed using equations 158-3 and 158-4 of this section. Where the
regulated material is organic HAP's, the list of organic HAP's provided
in table 2 of 40 CFR part 63, subpart F, shall be used.
(iii) The percent reduction in TOC (minus methane and ethane) or
total regulated material shall be calculated using Equation 158-5 of
this section:

(iv) If the vent stream entering a boiler or process heater with a
design capacity less than 44 megawatts (150 million British thermal
units) is introduced with the combustion air or as a secondary fuel,
the weight-percent reduction of total regulated material or TOC (minus
methane and ethane) across the device shall be determined by comparing
the TOC (minus methane and ethane) or total regulated material in all
combusted vent streams and primary and secondary fuels with the TOC
(minus methane and ethane) or total regulated material exiting the
combustion device, respectively.
(v) Method 25A of appendix A of 40 CFR part 60 may also be used for
the purpose of determining compliance with the percent reduction
requirement for transfer racks.

interval j, kilograms.
F = 10-6 = Conversion factor, (cubic meters regulated
material per cubic meters air) * (parts per million by volume)
-1.
K = Density, kilograms per standard cubic meter regulated material. You
may use 659 kilograms per standard cubic meter regulated material.
(Note: The density term cancels out when the percent reduction is
calculated. Therefore, the density used has no effect. The density of
hexane is given so that it can be used to maintain the units of
Mj.)
Vs = Volume of air-vapor mixture exhausted at standard
conditions, 20 deg.C and 760 millimeters of mercury (30 inches of

halides and halogens, the sampling site shall be located at the outlet
of the scrubber or other halogen reduction device and prior to any
releases to the atmosphere.
(2) Except as provided in paragraph (a)(2) of this section, Method
26 or Method 26A of appendix A of 40 CFR part 60 shall be used to
determine the concentration, in milligrams per dry standard cubic
meter, of total hydrogen halides and halogens that may be present in
the vent stream. The mass emissions of each hydrogen halide and halogen
compound shall be calculated from the measured concentrations and the
gas stream flow rate.
(3) To determine compliance with the percent removal efficiency,
the mass emissions for any hydrogen halides and halogens present at the
inlet of the halogen reduction device shall be summed together. The
mass emissions of the compounds present at the outlet of the scrubber
or other halogen reduction device shall be summed together. Percent
reduction shall be determined by comparison of the summed inlet and
outlet measurements.
(4) To demonstrate compliance with the less than 0.45 kilogram per
hour (0.99 pound per hour) outlet emission limit, the test results must
show that the mass emission rate of total hydrogen halides and halogens
measured at the outlet of the scrubber or other halogen reduction
device is below 0.45 kilogram per hour (0.99 pound per hour).

CPMS breakdown or malfunction. During these periods, it is not
necessary to calculate hourly averages; or
(4) A record as required by an alternative approved under
Sec. 65.162(d).
(b) Excluded data. Monitoring data recorded during the following
periods shall not be included in any average computed to determine
compliance under this subpart:
[[Page 78350]]
(1) Monitoring system breakdowns, repairs, preventive maintenance,
calibration checks, and zero (low-level) and high-level adjustments;
(2) Periods of non-operation of the process unit (or portion
thereof), resulting in cessation of the emissions to which the

(c) Records of daily averages. In addition to the records specified
in paragraph (a) of this section, owners or operators shall also keep
records as specified in paragraphs (c)(1) and (2) of this section
unless an alternative monitoring or recordkeeping system has been
requested and approved under Sec. 65.162(d).
(1) Except as specified in paragraph (c)(2) of this section, daily
average values of each continuously monitored parameter shall be
calculated for each operating day. Data meeting the specifications of
paragraph (b) of this section shall not be included in the average. The
data shall be reported in the periodic report as specified in
Sec. 65.166(f), if applicable.
(i) The daily average shall be calculated as the average of all
values for a monitored parameter recorded during the operating day as
specified in paragraph (a)(1), (2), or (3) of this section. The average
shall cover a 24-hour period if operation is continuous, or the number
of hours of operation per operating day if operation is not continuous
(for example, for high-throughput transfer racks, the average shall
cover periods of loading). If values are measured more frequently than
once per minute, a single value for each minute may be used to
calculate the daily average instead of all measured values.
(ii) The operating day shall be the period defined in the operating
permit or the Initial Compliance Status Report. It may be from midnight
to midnight or another daily period.
(2) If all monitored parameter values recorded under paragraph
(a)(1), (2), or (3) of this section, during an operating day are within
the range established in the Initial Compliance Status Report or in the
operating permit, the owner or operator does not have to calculate a
daily average value for the operating day and may record that all
values were within the range. The owner or operator must continue to
retain the raw data, 15-minute averages, or the hourly averages
required under paragraph (a)(1), (2), or (3) of this section.
(d) Valid data. Unless determined to be excluded data according to
paragraph (b) of this section, the data collected pursuant to
paragraphs (a) through (c) of this section shall be considered valid.
(e) Alternative recordkeeping. For any parameter with respect to
any item of equipment, the owner or operator may implement the
recordkeeping requirements in paragraph (e)(1) or (2) of this section
as alternatives to the continuous parameter monitoring and
recordkeeping provisions listed in paragraphs (a) through (c) of this
section. The owner or operator shall retain each record required by
paragraph (e)(1) or (2) of this section as provided in Sec. 65.4.
(1) The owner or operator may retain only the daily average value
and is not required to retain more frequently monitored operating
parameter values for a monitored parameter with respect to an item of
equipment if the requirements of paragraphs (e)(1)(i) through (vi) of
this section are met. The owner or operator shall notify the
Administrator of implementation of paragraph (e)(1) of this section in
the Initial Compliance Status Report as required in Sec. 65.165(e) or,
if the Initial Compliance Status Report has already been submitted, in
the periodic report as required in Sec. 65.166(f)(4) immediately
preceding implementation of the requirements of paragraph (e)(1) of
this section.
(i) The monitoring system can detect unrealistic or impossible data
during periods of operation other than startups, shutdowns, or
malfunctions (for example, a temperature reading of -200 deg.C on a
boiler) and will alert the operator by alarm or other means. The owner
or operator shall record the occurrence. All instances of the alarm or
other alert in an operating day constitute a single occurrence.
(ii) The monitoring system shall generate a running average of the
monitoring values, updated at least hourly throughout each operating
day, that have been obtained during that operating day, and the
capability to observe this average is readily available to the
Administrator on-site during the operating day. All instances in an
operating day constitute a single occurrence. The owner or operator
shall record the occurrence of any period meeting the following
criteria:
(A) The running average is above the maximum or below the minimum
established limits;
(B) The running average is based on at least six 1-hour average
values;
(C) The running average reflects a period of operation other than a
startup, shutdown, or malfunction.
(iii) The monitoring system shall be capable of detecting
unchanging data during periods of operation other than startups,
shutdowns, or malfunctions except in circumstances where the presence
of unchanging data is the expected operating condition based on past
experience (for example, pH in some scrubbers), and will alert the
operator by alarm or other means. The owner or operator shall record
the occurrence. All instances of the alarm or other alert in an
operating day constitute a single occurrence.
(iv) The monitoring system shall alert the owner or operator by an
alarm if the running average parameter value calculated under paragraph
(e)(1)(ii) of this section reaches a set point that is appropriately
related to the established limit for the parameter that is being
monitored.
(v) The owner or operator shall verify and document the proper
functioning of the monitoring system, including its ability to comply
with the requirements of paragraph (e)(1) of this section, at the
following times:
(A) Upon initial installation;
(B) Annually after initial installation; and
(C) After any change to the programming or equipment constituting
the monitoring system, that might reasonably be expected to alter the
monitoring system's ability to comply with the requirements of this
section.
(vi) The owner or operator shall retain the following records:
(A) Identification of each parameter for each item of equipment for
which the owner or operator has elected to comply with the requirements
of Sec. 65.162(e).
(B) A description of the applicable monitoring system(s) and of how
compliance will be achieved with each requirement of paragraphs
(e)(1)(i) through (v) of this section. The description shall identify
the location and format (for example, on-line storage; log entries) for
each required record. If the description changes, the owner or operator
shall retain both the current and the most recent outdated description.
(C) A description and the date of any change to the monitoring
system that would reasonably be expected to affect its ability to
comply with the requirements of paragraph (e)(1) of this section.
(D) Owners and operators shall retain the current description of
the monitoring system as long as the description is current, but not
less than 5 years from the date of its creation. The current
description shall be retained on-site at all times or be accessible
from a central location by computer or other means that provide access
within 2 hours after a request. The owner or
[[Page 78351]]
operator shall retain the most recent outdated description at least
until 5 years from the date of its creation. The outdated description
shall be retained on-site (or accessible from a central location by
computer that provides access within 2 hours after a request) at least
6 months after being outdated. Thereafter, the outdated description may
be stored off-site.
(2) If an owner or operator has elected to implement the
requirements of paragraph (e)(1) of this section and a period of 6
consecutive months has passed without an excursion as defined in
paragraph (e)(2)(iv) of this section, the owner or operator is no
longer required to record the daily average value for that parameter
for that unit of equipment for any operating day when the daily average
value is less than the maximum or greater than the minimum established
limit. With approval by the Administrator, monitoring data generated
prior to the compliance date of this subpart shall be credited toward
the period of 6 consecutive months if the parameter limit and the
monitoring were required and/or approved by the Administrator.
(i) If the owner or operator elects not to retain the daily average
values, the owner or operator shall notify the Administrator in the
next periodic report. The notification shall identify the parameter and
unit of equipment.
(ii) If there is an excursion as defined in paragraph (e)(2)(iv) of
this section on any operating day after the owner or operator has
ceased recording daily averages as provided in paragraph (e)(2) of this
section, the owner or operator shall immediately resume retaining the
daily average value for each day and shall notify the Administrator in
the next periodic report. The owner or operator shall continue to
retain each daily average value until another period of 6 consecutive
months has passed without an excursion.
(iii) The owner or operator shall retain the records specified in
paragraphs (e)(1)(i) through (vi) of this section for the duration
specified in Sec. 65.4. For any calendar week, if compliance with
paragraphs (e)(1)(i) through (iv) of this section does not result in
retention of a record of at least one occurrence or measured parameter
value, the owner or operator shall record and retain at least one
parameter value during a period of operation other than a startup,
shutdown, or malfunction.
(iv) For purposes of paragraph (e) of this section, an excursion
means that the daily average value of monitoring data for a parameter
is greater than the maximum or less than the minimum established value
except as provided in the following:
(A) The daily average value during any startup, shutdown, or
malfunction shall not be considered an excursion for purposes of this
paragraph (e) if the owner or operator follows the applicable
provisions of the startup, shutdown, and malfunction plan required by
Sec. 65.6.
(B) Excused excursions described in Sec. 65.156(d)(2) and
excursions described in Sec. 65.156(d)(3) do not count toward the
number of excursions for purposes of this paragraph (e).
