                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2023), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not dropped in error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

    (c) Neither a request for plans review nor advice furnished by the 
Administrator in response to such request shall (1) relieve an owner or 
operator of legal responsibility for compliance with any provision of 
this part or of any applicable State or local requirement, or (2) 
prevent the Administrator from implementing or enforcing any provision 
of this part or taking any other action authorized by the Act.

This notification shall be postmarked not less than 30 days prior to the 
date of the performance test.
    (b) Any owner or operator subject to the provisions of this part 
shall maintain records of the occurrence and duration of any startup, 
shutdown, or malfunction in the operation of an affected facility; any 
malfunction of the air pollution control equipment; or any periods 
during which a continuous monitoring system or monitoring device is 
inoperative.
    (c) Each owner or operator required to install a continuous 
monitoring device shall submit excess emissions and monitoring systems 
performance report (excess emissions are defined in applicable subparts) 
and-or summary report form (see paragraph (d) of this section) to the 
Administrator semiannually, except when: more frequent reporting is 
specifically required by an applicable subpart; or the Administrator, on 
a case-by-case basis, determines that more frequent reporting is 
necessary to accurately assess the compliance status of the source. All 
reports shall be postmarked by the 30th day following the end of each 
six-month period. Written reports of excess emissions shall include the 
following information:
    (1) The magnitude of excess emissions computed in accordance with 
Sec. 60.13(h), any conversion factor(s) used, and the date and time of 
commencement and completion of each time period of excess emissions. The 
process operating time during the reporting period.
    (2) Specific identification of each period of excess emissions that 
occurs during startups, shutdowns, and malfunctions of the affected 
facility. The nature and cause of any malfunction (if known), the 
corrective action taken or preventative measures adopted.
    (3) The date and time identifying each period during which the 
continuous monitoring system was inoperative except for zero and span 
checks and the nature of the system repairs or adjustments.
    (4) When no excess emissions have occurred or the continuous 
monitoring system(s) have not been inoperative, repaired, or adjusted, 
such information shall be stated in the report.
    (d) The summary report form shall contain the information and be in 
the format shown in figure 1 unless otherwise specified by the 
Administrator. One summary report form shall be submitted for each 
pollutant monitored at each affected facility.
    (1) If the total duration of excess emissions for the reporting 
period is less than 1 percent of the total operating time for the 
reporting period and CMS downtime for the reporting period is less than 
5 percent of the total operating time for the reporting period, only the 
summary report form shall be submitted and the excess emission report 
described in Sec. 60.7(c) need not be submitted unless requested by the 
Administrator.
    (2) If the total duration of excess emissions for the reporting 
period is 1 percent or greater of the total operating time for the 
reporting period or the total CMS downtime for the reporting period is 5 
percent or greater of the total operating time for the reporting period, 
the summary report form and the excess emission report described in 
Sec. 60.7(c) shall both be submitted.

Date

    (e)(1) Notwithstanding the frequency of reporting requirements 
specified in paragraph (c) of this section, an owner or operator who is 
required by an applicable subpart to submit excess emissions and 
monitoring systems performance reports (and summary reports) on a 
quarterly (or more frequent) basis may reduce the frequency of reporting 
for that standard to semiannual if the following conditions are met:
    (i) For 1 full year (e.g., 4 quarterly or 12 monthly reporting 
periods) the affected facility's excess emissions and monitoring systems 
reports submitted to comply with a standard under this part continually 
demonstrate that the facility is in compliance with the applicable 
standard;
    (ii) The owner or operator continues to comply with all 
recordkeeping and monitoring requirements specified in this subpart and 
the applicable standard; and
    (iii) The Administrator does not object to a reduced frequency of 
reporting for the affected facility, as provided in paragraph (e)(2) of 
this section.
    (2) The frequency of reporting of excess emissions and monitoring 
systems performance (and summary) reports may be reduced only after the 
owner or operator notifies the Administrator in writing of his or her 
intention to make such a change and the Administrator does not object to 
the intended change. In deciding whether to approve a reduced frequency 
of reporting, the Administrator may review information concerning the 
source's entire previous performance history during the required 
recordkeeping period prior to the intended change, including performance 
test results, monitoring data, and evaluations of an owner or operator's 
conformance with operation and maintenance requirements. Such 
information may be used by the Administrator to make a judgment about 
the source's potential for noncompliance in the future. If the 
Administrator disapproves the owner or operator's request to reduce the 
frequency of reporting, the Administrator will notify the owner or 
operator in writing within 45 days after receiving notice of the owner 
or operator's intention. The notification from the Administrator to the 
owner or operator will specify the grounds on which the disapproval is

[[Page 57]]

based. In the absence of a notice of disapproval within 45 days, 
approval is automatically granted.
    (3) As soon as monitoring data indicate that the affected facility 
is not in compliance with any emission limitation or operating parameter 
specified in the applicable standard, the frequency of reporting shall 
revert to the frequency specified in the applicable standard, and the 
owner or operator shall submit an excess emissions and monitoring 
systems performance report (and summary report, if required) at the next 
appropriate reporting period following the noncomplying event. After 
demonstrating compliance with the applicable standard for another full 
year, the owner or operator may again request approval from the 
Administrator to reduce the frequency of reporting for that standard as 
provided for in paragraphs (e)(1) and (e)(2) of this section.
    (f) Any owner or operator subject to the provisions of this part 
shall maintain a file of all measurements, including continuous 
monitoring system, monitoring device, and performance testing 
measurements; all continuous monitoring system performance evaluations; 
all continuous monitoring system or monitoring device calibration 
checks; adjustments and maintenance performed on these systems or 
devices; and all other information required by this part recorded in a 
permanent form suitable for inspection. The file shall be retained for 
at least two years following the date of such measurements, maintenance, 
reports, and records, except as follows:
    (1) This paragraph applies to owners or operators required to 
install a continuous emissions monitoring system (CEMS) where the CEMS 
installed is automated, and where the calculated data averages do not 
exclude periods of CEMS breakdown or malfunction. An automated CEMS 
records and reduces the measured data to the form of the pollutant 
emission standard through the use of a computerized data acquisition 
system. In lieu of maintaining a file of all CEMS subhourly measurements 
as required under paragraph (f) of this section, the owner or operator 
shall retain the most recent consecutive three averaging periods of 
subhourly measurements and a file that contains a hard copy of the data 
acquisition system algorithm used to reduce the measured data into the 
reportable form of the standard.
    (2) This paragraph applies to owners or operators required to 
install a CEMS where the measured data is manually reduced to obtain the 
reportable form of the standard, and where the calculated data averages 
do not exclude periods of CEMS breakdown or malfunction. In lieu of 
maintaining a file of all CEMS subhourly measurements as required under 
paragraph (f) of this section, the owner or operator shall retain all 
subhourly measurements for the most recent reporting period. The 
subhourly measurements shall be retained for 120 days from the date of 
the most recent summary or excess emission report submitted to the 
Administrator.
    (3) The Administrator or delegated authority, upon notification to 
the source, may require the owner or operator to maintain all 
measurements as required by paragraph (f) of this section, if the 
Administrator or the delegated authority determines these records are 
required to more accurately assess the compliance status of the affected 
source.
    (g) If notification substantially similar to that in paragraph (a) 
of this section is required by any other State or local agency, sending 
the Administrator a copy of that notification will satisfy the 
requirements of paragraph (a) of this section.
    (h) Individual subparts of this part may include specific provisions 
which clarify or make inapplicable the provisions set forth in this 
section.

Sec. 60.8  Performance tests.

    (a) Except as specified in paragraphs (a)(1),(a)(2), (a)(3), and 
(a)(4) of this section, within 60 days after achieving the maximum 
production rate at which the affected facility will be operated, but not 
later than 180 days after initial

[[Page 58]]

startup of such facility, or at such other times specified by this part, 
and at such other times as may be required by the Administrator under 
section 114 of the Act, the owner or operator of such facility shall 
conduct performance test(s) and furnish the Administrator a written 
report of the results of such performance test(s).
    (1) If a force majeure is about to occur, occurs, or has occurred 
for which the affected owner or operator intends to assert a claim of 
force majeure, the owner or operator shall notify the Administrator, in 
writing as soon as practicable following the date the owner or operator 
first knew, or through due diligence should have known that the event 
may cause or caused a delay in testing beyond the regulatory deadline, 
but the notification must occur before the performance test deadline 
unless the initial force majeure or a subsequent force majeure event 
delays the notice, and in such cases, the notification shall occur as 
soon as practicable.
    (2) The owner or operator shall provide to the Administrator a 
written description of the force majeure event and a rationale for 
attributing the delay in testing beyond the regulatory deadline to the 
force majeure; describe the measures taken or to be taken to minimize 
the delay; and identify a date by which the owner or operator proposes 
to conduct the performance test. The performance test shall be conducted 
as soon as practicable after the force majeure occurs.
    (3) The decision as to whether or not to grant an extension to the 
performance test deadline is solely within the discretion of the 
Administrator. The Administrator will notify the owner or operator in 
writing of approval or disapproval of the request for an extension as 
soon as practicable.
    (4) Until an extension of the performance test deadline has been 
approved by the Administrator under paragraphs (a)(1), (2), and (3) of 
this section, the owner or operator of the affected facility remains 
strictly subject to the requirements of this part.
    (b) Performance tests shall be conducted and data reduced in 
accordance with the test methods and procedures contained in each 
applicable subpart unless the Administrator (1) specifies or approves, 
in specific cases, the use of a reference method with minor changes in 
methodology, (2) approves the use of an equivalent method, (3) approves 
the use of an alternative method the results of which he has determined 
to be adequate for indicating whether a specific source is in 
compliance, (4) waives the requirement for performance tests because the 
owner or operator of a source has demonstrated by other means to the 
Administrator's satisfaction that the affected facility is in compliance 
with the standard, or (5) approves shorter sampling times and smaller 
sample volumes when necessitated by process variables or other factors. 
Nothing in this paragraph shall be construed to abrogate the 
Administrator's authority to require testing under section 114 of the 
Act.
    (c) Performance tests shall be conducted under such conditions as 
the Administrator shall specify to the plant operator based on 
representative performance of the affected facility. The owner or 
operator shall make available to the Administrator such records as may 
be necessary to determine the conditions of the performance tests. 
Operations during periods of startup, shutdown, and malfunction shall 
not constitute representative conditions for the purpose of a 
performance test nor shall emissions in excess of the level of the 
applicable emission limit during periods of startup, shutdown, and 
malfunction be considered a violation of the applicable emission limit 
unless otherwise specified in the applicable standard.
    (d) The owner or operator of an affected facility shall provide the 
Administrator at least 30 days prior notice of any performance test, 
except as specified under other subparts, to afford the Administrator 
the opportunity to have an observer present. If after 30 days notice for 
an initially scheduled performance test, there is a delay (due to 
operational problems, etc.) in conducting the scheduled performance 
test, the owner or operator of an affected facility shall notify the 
Administrator (or delegated State or local agency) as soon as possible 
of any delay in the original test date, either by providing

[[Page 59]]

at least 7 days prior notice of the rescheduled date of the performance 
test, or by arranging a rescheduled date with the Administrator (or 
delegated State or local agency) by mutual agreement.
    (e) The owner or operator of an affected facility shall provide, or 
cause to be provided, performance testing facilities as follows:
    (1) Sampling ports adequate for test methods applicable to such 
facility. This includes (i) constructing the air pollution control 
system such that volumetric flow rates and pollutant emission rates can 
be accurately determined by applicable test methods and procedures and 
(ii) providing a stack or duct free of cyclonic flow during performance 
tests, as demonstrated by applicable test methods and procedures.
    (2) Safe sampling platform(s).
    (3) Safe access to sampling platform(s).
    (4) Utilities for sampling and testing equipment.
    (f) Unless otherwise specified in the applicable subpart, each 
performance test shall consist of three separate runs using the 
applicable test method.
    (1) Each run shall be conducted for the time and under the 
conditions specified in the applicable standard. For the purpose of 
determining compliance with an applicable standard, the arithmetic means 
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.
    (2) Contents of report (electronic or paper submitted copy). Unless 
otherwise specified in a relevant standard or test method, or as 
otherwise approved by the Administrator in writing, the report for a 
performance test shall include the elements identified in paragraphs 
(f)(2)(i) through (vi) of this section.
    (i) General identification information for the facility including a 
mailing address, the physical address, the owner or operator or 
responsible official (where applicable) and his/her email address, and 
the appropriate Federal Registry System (FRS) number for the facility.
    (ii) Purpose of the test including the applicable regulation(s) 
requiring the test, the pollutant(s) and other parameters being 
measured, the applicable emission standard and any process parameter 
component, and a brief process description.
    (iii) Description of the emission unit tested including fuel burned, 
control devices, and vent characteristics; the appropriate source 
classification code (SCC); the permitted maximum process rate (where 
applicable); and the sampling location.
    (iv) Description of sampling and analysis procedures used and any 
modifications to standard procedures, quality assurance procedures and 
results, record of process operating conditions that demonstrate the 
applicable test conditions are met, and values for any operating 
parameters for which limits were being set during the test.
    (v) Where a test method requires you record or report, the following 
shall be included: Record of preparation of standards, record of 
calibrations, raw data sheets for field sampling, raw data sheets for 
field and laboratory analyses, chain-of-custody documentation, and 
example calculations for reported results.
    (vi) Identification of the company conducting the performance test 
including the primary office address, telephone number, and the contact 
for this test program including his/her email address.
    (g) The performance testing shall include a test method performance 
audit (PA) during the performance test. The PAs consist of blind audit 
samples supplied by an accredited audit sample provider and analyzed 
during the performance test in order to provide a measure of test data 
bias. Gaseous audit samples are designed to audit the performance of the 
sampling system as well as the analytical system and must be collected 
by the sampling system during the compliance test just as the compliance 
samples are collected. If a liquid or solid audit sample is designed

[[Page 60]]

to audit the sampling system, it must also be collected by the sampling 
system during the compliance test. If multiple sampling systems or 
sampling trains are used during the compliance test for any of the test 
methods, the tester is only required to use one of the sampling systems 
per method to collect the audit sample. The audit sample must be 
analyzed by the same analyst using the same analytical reagents and 
analytical system and at the same time as the compliance samples. 
Retests are required when there is a failure to produce acceptable 
results for an audit sample. However, if the audit results do not affect 
the compliance or noncompliance status of the affected facility, the 
compliance authority may waive the reanalysis requirement, further 
audits, or retests and accept the results of the compliance test. 
Acceptance of the test results shall constitute a waiver of the 
reanalysis requirement, further audits, or retests. The compliance 
authority may also use the audit sample failure and the compliance test 
results as evidence to determine the compliance or noncompliance status 
of the affected facility. A blind audit sample is a sample whose value 
is known only to the sample provider and is not revealed to the tested 
facility until after they report the measured value of the audit sample. 
For pollutants that exist in the gas phase at ambient temperature, the 
audit sample shall consist of an appropriate concentration of the 
pollutant in air or nitrogen that can be introduced into the sampling 
system of the test method at or near the same entry point as a sample 
from the emission source. If no gas phase audit samples are available, 
an acceptable alternative is a sample of the pollutant in the same 
matrix that would be produced when the sample is recovered from the 
sampling system as required by the test method. For samples that exist 
only in a liquid or solid form at ambient temperature, the audit sample 
shall consist of an appropriate concentration of the pollutant in the 
same matrix that would be produced when the sample is recovered from the 
sampling system as required by the test method. An accredited audit 
sample provider (AASP) is an organization that has been accredited to 
prepare audit samples by an independent, third party accrediting body.
    (1) The source owner, operator, or representative of the tested 
facility shall obtain an audit sample, if commercially available, from 
an AASP for each test method used for regulatory compliance purposes. No 
audit samples are required for the following test methods: Methods 3A 
and 3C of appendix A-3 of part 60, Methods 6C, 7E, 9, and 10 of appendix 
A-4 of part 60, Methods 18 and 19 of appendix A-6 of part 60, Methods 
20, 22, and 25A of appendix A-7 of part 60, Methods 30A and 30B of 
appendix A-8 of part 60, and Methods 303, 318, 320, and 321 of appendix 
A of part 63 of this chapter. If multiple sources at a single facility 
are tested during a compliance test event, only one audit sample is 
required for each method used during a compliance test. The compliance 
authority responsible for the compliance test may waive the requirement 
to include an audit sample if they believe that an audit sample is not 
necessary. ``Commercially available'' means that two or more independent 
AASPs have blind audit samples available for purchase. If the source 
owner, operator, or representative cannot find an audit sample for a 
specific method, the owner, operator, or representative shall consult 
the EPA Web site at the following URL, www.epa.gov/ttn/emc, to confirm 
whether there is a source that can supply an audit sample for that 
method. If the EPA Web site does not list an available audit sample at 
least 60 days prior to the beginning of the compliance test, the source 
owner, operator, or representative shall not be required to include an 
audit sample as part of the quality assurance program for the compliance 
test. When ordering an audit sample, the source owner, operator, or 
representative shall give the sample provider an estimate for the 
concentration of each pollutant that is emitted by the source or the 
estimated concentration of each pollutant based on the permitted level 
and the name, address, and phone number of the compliance authority. The 
source owner, operator, or representative shall report the results for 
the audit sample along with a summary of the emission test results for 
the audited pollutant to the

[[Page 61]]

compliance authority and shall report the results of the audit sample to 
the AASP. The source owner, operator, or representative shall make both 
reports at the same time and in the same manner or shall report to the 
compliance authority first and then report to the AASP. If the method 
being audited is a method that allows the samples to be analyzed in the 
field and the tester plans to analyze the samples in the field, the 
tester may analyze the audit samples prior to collecting the emission 
samples provided a representative of the compliance authority is present 
at the testing site. The tester may request and the compliance authority 
may grant a waiver to the requirement that a representative of the 
compliance authority must be present at the testing site during the 
field analysis of an audit sample. The source owner, operator, or 
representative may report the results of the audit sample to the 
compliance authority and report the results of the audit sample to the 
AASP prior to collecting any emission samples. The test protocol and 
final test report shall document whether an audit sample was ordered and 
utilized and the pass/fail results as applicable.
    (2) An AASP shall have and shall prepare, analyze, and report the 
true value of audit samples in accordance with a written technical 
criteria document that describes how audit samples will be prepared and 
distributed in a manner that will ensure the integrity of the audit 
sample program. An acceptable technical criteria document shall contain 
standard operating procedures for all of the following operations:
    (i) Preparing the sample;
    (ii) Confirming the true concentration of the sample;
    (iii) Defining the acceptance limits for the results from a well 
qualified tester. This procedure must use well established statistical 
methods to analyze historical results from well qualified testers. The 
acceptance limits shall be set so that there is 95 percent confidence 
that 90 percent of well qualified labs will produce future results that 
are within the acceptance limit range.
    (iv) Providing the opportunity for the compliance authority to 
comment on the selected concentration level for an audit sample;
    (v) Distributing the sample to the user in a manner that guarantees 
that the true value of the sample is unknown to the user;
    (vi) Recording the measured concentration reported by the user and 
determining if the measured value is within acceptable limits;
    (vii) The AASP shall report the results from each audit sample in a 
timely manner to the compliance authority and then to the source owner, 
operator, or representative. The AASP shall make both reports at the 
same time and in the same manner or shall report to the compliance 
authority first and then report to the source owner, operator, or 
representative. The results shall include the name of the facility 
tested, the date on which the compliance test was conducted, the name of 
the company performing the sample collection, the name of the company 
that analyzed the compliance samples including the audit sample, the 
measured result for the audit sample, and whether the testing company 
passed or failed the audit. The AASP shall report the true value of the 
audit sample to the compliance authority. The AASP may report the true 
value to the source owner, operator, or representative if the AASP's 
operating plan ensures that no laboratory will receive the same audit 
sample twice.
    (viii) Evaluating the acceptance limits of samples at least once 
every two years to determine in cooperation with the voluntary consensus 
standard body if they should be changed;
    (ix) Maintaining a database, accessible to the compliance 
authorities, of results from the audit that shall include the name of 
the facility tested, the date on which the compliance test was 
conducted, the name of the company performing the sample collection, the 
name of the company that analyzed the compliance samples including the 
audit sample, the measured result for the audit sample, the true value 
of the audit sample, the acceptance range for the measured value, and 
whether the testing company passed or failed the audit.
    (3) The accrediting body shall have a written technical criteria 
document

[[Page 62]]

that describes how it will ensure that the AASP is operating in 
accordance with the AASP technical criteria document that describes how 
audit samples are to be prepared and distributed. This document shall 
contain standard operating procedures for all of the following 
operations:
    (i) Checking audit samples to confirm their true value as reported 
by the AASP;
    (ii) Performing technical systems audits of the AASP's facilities 
and operating procedures at least once every two years;
    (iii) Providing standards for use by the voluntary consensus 
standard body to approve the accrediting body that will accredit the 
audit sample providers.
    (4) The technical criteria documents for the accredited sample 
providers and the accrediting body shall be developed through a public 
process guided by a voluntary consensus standards body (VCSB). The VCSB 
shall operate in accordance with the procedures and requirements in the 
Office of Management and Budget Circular A-119. A copy of Circular A-119 
is available upon request by writing the Office of Information and 
Regulatory Affairs, Office of Management and Budget, 725 17th Street, 
NW., Washington, DC 20503, by calling (202) 395-6880 or downloading 
online at http://standards.gov/standards __gov/a119.cfm. The VCSB shall 
approve all accrediting bodies. The Administrator will review all 
technical criteria documents. If the technical criteria documents do not 
meet the minimum technical requirements in paragraphs (g)(2) through 
(4)of this section, the technical criteria documents are not acceptable 
and the proposed audit sample program is not capable of producing audit 
samples of sufficient quality to be used in a compliance test. All 
acceptable technical criteria documents shall be posted on the EPA Web 
site at the following URL, http://www.epa.gov/ttn/emc.
    (h) Unless otherwise specified in the applicable subpart, each test 
location must be verified to be free of cyclonic flow and evaluated for 
the existence of emission gas stratification and the required number of 
sampling traverse points. If other procedures are not specified in the 
applicable subpart to the regulations, use the appropriate procedures in 
Method 1 to check for cyclonic flow and Method 7E to evaluate emission 
gas stratification and selection of sampling points.
    (i) Whenever the use of multiple calibration gases is required by a 
test method, performance specification, or quality assurance procedure 
in a part 60 standard or appendix, Method 205 of 40 CFR part 51, 
appendix M of this chapter, ``Verification of Gas Dilution Systems for 
Field Instrument Calibrations,'' may be used.

Sec. 60.9  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. (Information submitted voluntarily 
to the Administrator for the purposes of Sec. Sec. 60.5 and 60.6 is 
governed by Sec. Sec. 2.201 through 2.213 of this chapter and not by 
Sec. 2.301 of this chapter.)



Sec. 60.10  State authority.

    The provisions of this part shall not be construed in any manner to 
preclude any State or political subdivision thereof from:
    (a) Adopting and enforcing any emission standard or limitation 
applicable to an affected facility, provided that such emission standard 
or limitation is not less stringent than the standard applicable to such 
facility.
    (b) Requiring the owner or operator of an affected facility to 
obtain permits, licenses, or approvals prior to initiating construction, 
modification, or operation of such facility.



Sec. 60.11  Compliance with standards and maintenance requirements.

    (a) Compliance with standards in this part, other than opacity 
standards, shall be determined in accordance with performance tests 
established by Sec. 60.8,

[[Page 63]]

unless otherwise specified in the applicable standard.
    (b) Compliance with opacity standards in this part shall be 
determined by conducting observations in accordance with Method 9 in 
appendix A of this part, any alternative method that is approved by the 
Administrator, or as provided in paragraph (e)(5) of this section. For 
purposes of determining initial compliance, the minimum total time of 
observations shall be 3 hours (30 6-minute averages) for the performance 
test or other set of observations (meaning those fugitive-type emission 
sources subject only to an opacity standard).
    (c) The opacity standards set forth in this part shall apply at all 
times except during periods of startup, shutdown, malfunction, and as 
otherwise provided in the applicable standard.
    (d) At all times, including periods of startup, shutdown, and 
malfunction, owners and operators shall, to the extent practicable, 
maintain and operate any affected facility including associated air 
pollution control equipment in a manner consistent with good air 
pollution control practice for minimizing emissions. Determination of 
whether acceptable operating and maintenance procedures are being used 
will be based on information available to the Administrator which may 
include, but is not limited to, monitoring results, opacity 
observations, review of operating and maintenance procedures, and 
inspection of the source.
    (e)(1) For the purpose of demonstrating initial compliance, opacity 
observations shall be conducted concurrently with the initial 
performance test required in Sec. 60.8 unless one of the following 
conditions apply. If no performance test under Sec. 60.8 is required, 
then opacity observations shall be conducted within 60 days after 
achieving the maximum production rate at which the affected facility 
will be operated but no later than 180 days after initial startup of the 
facility. If visibility or other conditions prevent the opacity 
observations from being conducted concurrently with the initial 
performance test required under Sec. 60.8, the source owner or operator 
shall reschedule the opacity observations as soon after the initial 
performance test as possible, but not later than 30 days thereafter, and 
shall advise the Administrator of the rescheduled date. In these cases, 
the 30-day prior notification to the Administrator required in Sec. 
60.7(a)(6) shall be waived. The rescheduled opacity observations shall 
be conducted (to the extent possible) under the same operating 
conditions that existed during the initial performance test conducted 
under Sec. 60.8. The visible emissions observer shall determine whether 
visibility or other conditions prevent the opacity observations from 
being made concurrently with the initial performance test in accordance 
with procedures contained in Method 9 of appendix B of this part. 
Opacity readings of portions of plumes which contain condensed, 
uncombined water vapor shall not be used for purposes of determing 
compliance with opacity standards. The owner or operator of an affected 
facility shall make available, upon request by the Administrator, such 
records as may be necessary to determine the conditions under which the 
visual observations were made and shall provide evidence indicating 
proof of current visible observer emission certification. Except as 
provided in paragraph (e)(5) of this section, the results of continuous 
monitoring by transmissometer which indicate that the opacity at the 
time visual observations were made was not in excess of the standard are 
probative but not conclusive evidence of the actual opacity of an 
emission, provided that the source shall meet the burden of proving that 
the instrument used meets (at the time of the alleged violation) 
Performance Specification 1 in appendix B of this part, has been 
properly maintained and (at the time of the alleged violation) that the 
resulting data have not been altered in any way.
    (2) Except as provided in paragraph (e)(3) of this section, the 
owner or operator of an affected facility to which an opacity standard 
in this part applies shall conduct opacity observations in accordance 
with paragraph (b) of this section, shall record the opacity of 
emissions, and shall report to the Administrator the opacity results 
along

[[Page 64]]

with the results of the initial performance test required under Sec. 
60.8. The inability of an owner or operator to secure a visible 
emissions observer shall not be considered a reason for not conducting 
the opacity observations concurrent with the initial performance test.
    (3) The owner or operator of an affected facility to which an 
opacity standard in this part applies may request the Administrator to 
determine and to record the opacity of emissions from the affected 
facility during the initial performance test and at such times as may be 
required. The owner or operator of the affected facility shall report 
the opacity results. Any request to the Administrator to determine and 
to record the opacity of emissions from an affected facility shall be 
included in the notification required in Sec. 60.7(a)(6). If, for some 
reason, the Administrator cannot determine and record the opacity of 
emissions from the affected facility during the performance test, then 
the provisions of paragraph (e)(1) of this section shall apply.
    (4) An owner or operator of an affected facility using a continuous 
opacity monitor (transmissometer) shall record the monitoring data 
produced during the initial performance test required by Sec. 60.8 and 
shall furnish the Administrator a written report of the monitoring 
results along with Method 9 and Sec. 60.8 performance test results.
    (5) An owner or operator of an affected facility subject to an 
opacity standard may submit, for compliance purposes, continuous opacity 
monitoring system (COMS) data results produced during any performance 
test required under Sec. 60.8 in lieu of Method 9 observation data. If 
an owner or operator elects to submit COMS data for compliance with the 
opacity standard, he shall notify the Administrator of that decision, in 
writing, at least 30 days before any performance test required under 
Sec. 60.8 is conducted. Once the owner or operator of an affected 
facility has notified the Administrator to that effect, the COMS data 
results will be used to determine opacity compliance during subsequent 
tests required under Sec. 60.8 until the owner or operator notifies the 
Administrator, in writing, to the contrary. For the purpose of 
determining compliance with the opacity standard during a performance 
test required under Sec. 60.8 using COMS data, the minimum total time 
of COMS data collection shall be averages of all 6-minute continuous 
periods within the duration of the mass emission performance test. 
Results of the COMS opacity determinations shall be submitted along with 
the results of the performance test required under Sec. 60.8. The owner 
or operator of an affected facility using a COMS for compliance purposes 
is responsible for demonstrating that the COMS meets the requirements 
specified in Sec. 60.13(c) of this part, that the COMS has been 
properly maintained and operated, and that the resulting data have not 
been altered in any way. If COMS data results are submitted for 
compliance with the opacity standard for a period of time during which 
Method 9 data indicates noncompliance, the Method 9 data will be used to 
determine compliance with the opacity standard.
    (6) Upon receipt from an owner or operator of the written reports of 
the results of the performance tests required by Sec. 60.8, the opacity 
observation results and observer certification required by Sec. 
60.11(e)(1), and the COMS results, if applicable, the Administrator will 
make a finding concerning compliance with opacity and other applicable 
standards. If COMS data results are used to comply with an opacity 
standard, only those results are required to be submitted along with the 
performance test results required by Sec. 60.8. If the Administrator 
finds that an affected facility is in compliance with all applicable 
standards for which performance tests are conducted in accordance with 
Sec. 60.8 of this part but during the time such performance tests are 
being conducted fails to meet any applicable opacity standard, he shall 
notify the owner or operator and advise him that he may petition the 
Administrator within 10 days of receipt of notification to make 
appropriate adjustment to the opacity standard for the affected 
facility.
    (7) The Administrator will grant such a petition upon a 
demonstration by the

[[Page 65]]

owner or operator that the affected facility and associated air 
pollution control equipment was operated and maintained in a manner to 
minimize the opacity of emissions during the performance tests; that the 
performance tests were performed under the conditions established by the 
Administrator; and that the affected facility and associated air 
pollution control equipment were incapable of being adjusted or operated 
to meet the applicable opacity standard.
    (8) The Administrator will establish an opacity standard for the 
affected facility meeting the above requirements at a level at which the 
source will be able, as indicated by the performance and opacity tests, 
to meet the opacity standard at all times during which the source is 
meeting the mass or concentration emission standard. The Administrator 
will promulgate the new opacity standard in the Federal Register.
    (f) Special provisions set forth under an applicable subpart shall 
supersede any conflicting provisions in paragraphs (a) through (e) of 
this section.
    (g) For the purpose of submitting compliance certifications or 
establishing whether or not a person has violated or is in violation of 
any standard in this part, nothing in this part shall preclude the use, 
including the exclusive use, of any credible evidence or information, 
relevant to whether a source would have been in compliance with 
applicable requirements if the appropriate performance or compliance 
test or procedure had been performed.

Sec. 60.12  Circumvention.

    No owner or operator subject to the provisions of this part shall 
build, erect, install, or use any article, machine, equipment or 
process, the use of which conceals an emission which would otherwise 
constitute a violation of an applicable standard. Such concealment 
includes, but is not limited to, the use of gaseous diluents to achieve 
compliance with an opacity standard or with a standard which is based on 
the concentration of a pollutant in the gases discharged to the 
atmosphere.

[39 FR 9314, Mar. 8, 1974]



Sec. 60.13  Monitoring requirements.

    (a) For the purposes of this section, all continuous monitoring 
systems required under applicable subparts shall be subject to the 
provisions of this section upon promulgation of performance 
specifications for continuous monitoring systems under appendix B to 
this part and, if the continuous monitoring system is used to 
demonstrate compliance with emission limits on a continuous basis, 
appendix F to this part, unless otherwise specified in an applicable 
subpart or by the Administrator. Appendix F is applicable December 4, 
1987.
    (b) All continuous monitoring systems and monitoring devices shall 
be installed and operational prior to conducting performance tests under 
Sec. 60.8. Verification of operational status shall, as a minimum, 
include completion of the manufacturer's written requirements or 
recommendations for installation, operation, and calibration of the 
device.
    (c) If the owner or operator of an affected facility elects to 
submit continous opacity monitoring system (COMS) data for compliance 
with the opacity standard as provided under Sec. 60.11(e)(5), he shall 
conduct a performance evaluation of the COMS as specified in Performance 
Specification 1, appendix B, of this part before the performance test 
required under Sec. 60.8 is conducted. Otherwise, the owner or operator 
of an affected facility shall conduct a performance evaluation of the 
COMS or continuous emission monitoring system (CEMS) during any 
performance test required under Sec. 60.8 or within 30 days thereafter 
in accordance with the applicable performance specification in appendix 
B of this part, The owner or operator of an affected facility shall 
conduct COMS or CEMS performance evaluations at such other times as may 
be required by the Administrator under section 114 of the Act.

[[Page 66]]

    (1) The owner or operator of an affected facility using a COMS to 
determine opacity compliance during any performance test required under 
Sec. 60.8 and as described in Sec. 60.11(e)(5) shall furnish the 
Administrator two or, upon request, more copies of a written report of 
the results of the COMS performance evaluation described in paragraph 
(c) of this section at least 10 days before the performance test 
required under Sec. 60.8 is conducted.
    (2) Except as provided in paragraph (c)(1) of this section, the 
owner or operator of an affected facility shall furnish the 
Administrator within 60 days of completion two or, upon request, more 
copies of a written report of the results of the performance evaluation.
    (d)(1) Owners and operators of a CEMS installed in accordance with 
the provisions of this part, must check the zero (or low level value 
between 0 and 20 percent of span value) and span (50 to 100 percent of 
span value) calibration drifts at least once each operating day in 
accordance with a written procedure. The zero and span must, at a 
minimum, be adjusted whenever either the 24-hour zero drift or the 24-
hour span drift exceeds two times the limit of the applicable 
performance specification in appendix B of this part. The system must 
allow the amount of the excess zero and span drift to be recorded and 
quantified whenever specified. Owners and operators of a COMS installed 
in accordance with the provisions of this part must check the zero and 
upscale (span) calibration drifts at least once daily. For a particular 
COMS, the acceptable range of zero and upscale calibration materials is 
defined in the applicable version of PS-1 in appendix B of this part. 
For a COMS, the optical surfaces, exposed to the effluent gases, must be 
cleaned before performing the zero and upscale drift adjustments, except 
for systems using automatic zero adjustments. The optical surfaces must 
be cleaned when the cumulative automatic zero compensation exceeds 4 
percent opacity.
    (2) Unless otherwise approved by the Administrator, the following 
procedures must be followed for a COMS. Minimum procedures must include 
an automated method for producing a simulated zero opacity condition and 
an upscale opacity condition using a certified neutral density filter or 
other related technique to produce a known obstruction of the light 
beam. Such procedures must provide a system check of all active analyzer 
internal optics with power or curvature, all active electronic circuitry 
including the light source and photodetector assembly, and electronic or 
electro-mechanical systems and hardware and or software used during 
normal measurement operation.
    (e) Except for system breakdowns, repairs, calibration checks, and 
zero and span adjustments required under paragraph (d) of this section, 
all continuous monitoring systems shall be in continuous operation and 
shall meet minimum frequency of operation requirements as follows:
    (1) All continuous monitoring systems referenced by paragraph (c) of 
this section for measuring opacity of emissions shall complete a minimum 
of one cycle of sampling and analyzing for each successive 10-second 
period and one cycle of data recording for each successive 6-minute 
period.
    (2) All continuous monitoring systems referenced by paragraph (c) of 
this section for measuring emissions, except opacity, shall complete a 
minimum of one cycle of operation (sampling, analyzing, and data 
recording) for each successive 15-minute period.
    (f) All continuous monitoring systems or monitoring devices shall be 
installed such that representative measurements of emissions or process 
parameters from the affected facility are obtained. Additional 
procedures for location of continuous monitoring systems contained in 
the applicable Performance Specifications of appendix B of this part 
shall be used.
    (g) When the effluents from a single affected facility or two or 
more affected facilities subject to the same emission standards are 
combined before being released to the atmosphere, the owner or operator 
may install applicable continuous monitoring systems on each effluent or 
on the combined effluent. When the affected facilities are not subject 
to the same emission standards, separate continuous monitoring systems 
shall be installed on each effluent. When the effluent

[[Page 67]]

from one affected facility is released to the atmosphere through more 
than one point, the owner or operator shall install an applicable 
continuous monitoring system on each separate effluent unless the 
installation of fewer systems is approved by the Administrator. When 
more than one continuous monitoring system is used to measure the 
emissions from one affected facility (e.g., multiple breechings, 
multiple outlets), the owner or operator shall report the results as 
required from each continuous monitoring system.
    (h)(1) Owners or operators of all continuous monitoring systems for 
measurement of opacity shall reduce all data to 6-minute averages and 
for continuous monitoring systems other than opacity to 1-hour averages 
for time periods as defined in Sec. 60.2. Six-minute opacity averages 
shall be calculated from 36 or more data points equally spaced over each 
6-minute period.
    (2) For continuous monitoring systems other than opacity, 1-hour 
averages shall be computed as follows, except that the provisions 
pertaining to the validation of partial operating hours are only 
applicable for affected facilities that are required by the applicable 
subpart to include partial hours in the emission calculations:
    (i) Except as provided under paragraph (h)(2)(iii) of this section, 
for a full operating hour (any clock hour with 60 minutes of unit 
operation), at least four valid data points are required to calculate 
the hourly average, i.e., one data point in each of the 15-minute 
quadrants of the hour.
    (ii) Except as provided under paragraph (h)(2)(iii) of this section, 
for a partial operating hour (any clock hour with less than 60 minutes 
of unit operation), at least one valid data point in each 15-minute 
quadrant of the hour in which the unit operates is required to calculate 
the hourly average.
    (iii) For any operating hour in which required maintenance or 
quality-assurance activities are performed:
    (A) If the unit operates in two or more quadrants of the hour, a 
minimum of two valid data points, separated by at least 15 minutes, is 
required to calculate the hourly average; or
    (B) If the unit operates in only one quadrant of the hour, at least 
one valid data point is required to calculate the hourly average.
    (iv) If a daily calibration error check is failed during any 
operating hour, all data for that hour shall be invalidated, unless a 
subsequent calibration error test is passed in the same hour and the 
requirements of paragraph (h)(2)(iii) of this section are met, based 
solely on valid data recorded after the successful calibration.
    (v) For each full or partial operating hour, all valid data points 
shall be used to calculate the hourly average.
    (vi) Except as provided under paragraph (h)(2)(vii) of this section, 
data recorded during periods of continuous monitoring system breakdown, 
repair, calibration checks, and zero and span adjustments shall not be 
included in the data averages computed under this paragraph.
    (vii) Owners and operators complying with the requirements of Sec. 
60.7(f)(1) or (2) must include any data recorded during periods of 
monitor breakdown or malfunction in the data averages.
    (viii) When specified in an applicable subpart, hourly averages for 
certain partial operating hours shall not be computed or included in the 
emission averages (e.g., hours with < 30 minutes of unit operation under 
Sec. 60.47b(d)).
    (ix) Either arithmetic or integrated averaging of all data may be 
used to calculate the hourly averages. The data may be recorded in 
reduced or nonreduced form (e.g., ppm pollutant and percent 
O2 or ng/J of pollutant).
    (3) All excess emissions shall be converted into units of the 
standard using the applicable conversion procedures specified in the 
applicable subpart. After conversion into units of the standard, the 
data may be rounded to the same number of significant digits used in the 
applicable subpart to specify the emission limit.
    (i) After receipt and consideration of written application, the 
Administrator may approve alternatives to any monitoring procedures or 
requirements of this part including, but not limited to the following:
    (1) Alternative monitoring requirements when installation of a 
continuous monitoring system or monitoring

[[Page 68]]

device specified by this part would not provide accurate measurements 
due to liquid water or other interferences caused by substances in the 
effluent gases.
    (2) Alternative monitoring requirements when the affected facility 
is infrequently operated.
    (3) Alternative monitoring requirements to accommodate continuous 
monitoring systems that require additional measurements to correct for 
stack moisture conditions.
    (4) Alternative locations for installing continuous monitoring 
systems or monitoring devices when the owner or operator can demonstrate 
that installation at alternate locations will enable accurate and 
representative measurements.
    (5) Alternative methods of converting pollutant concentration 
measurements to units of the standards.
    (6) Alternative procedures for performing daily checks of zero and 
span drift that do not involve use of span gases or test cells.
    (7) Alternatives to the A.S.T.M. test methods or sampling procedures 
specified by any subpart.
    (8) Alternative continuous monitoring systems that do not meet the 
design or performance requirements in Performance Specification 1, 
appendix B, but adequately demonstrate a definite and consistent 
relationship between its measurements and the measurements of opacity by 
a system complying with the requirements in Performance Specification 1. 
The Administrator may require that such demonstration be performed for 
each affected facility.
    (9) Alternative monitoring requirements when the effluent from a 
single affected facility or the combined effluent from two or more 
affected facilities is released to the atmosphere through more than one 
point.
    (j) An alternative to the relative accuracy (RA) test specified in 
Performance Specification 2 of appendix B may be requested as follows:
    (1) An alternative to the reference method tests for determining RA 
is available for sources with emission rates demonstrated to be less 
than 50 percent of the applicable standard. A source owner or operator 
may petition the Administrator to waive the RA test in Section 8.4 of 
Performance Specification 2 and substitute the procedures in Section 
16.0 if the results of a performance test conducted according to the 
requirements in Sec. 60.8 of this subpart or other tests performed 
following the criteria in Sec. 60.8 demonstrate that the emission rate 
of the pollutant of interest in the units of the applicable standard is 
less than 50 percent of the applicable standard. For sources subject to 
standards expressed as control efficiency levels, a source owner or 
operator may petition the Administrator to waive the RA test and 
substitute the procedures in Section 16.0 of Performance Specification 2 
if the control device exhaust emission rate is less than 50 percent of 
the level needed to meet the control efficiency requirement. The 
alternative procedures do not apply if the continuous emission 
monitoring system is used to determine compliance continuously with the 
applicable standard. The petition to waive the RA test shall include a 
detailed description of the procedures to be applied. Included shall be 
location and procedure for conducting the alternative, the concentration 
or response levels of the alternative RA materials, and the other 
equipment checks included in the alternative procedure. The 
Administrator will review the petition for completeness and 
applicability. The determination to grant a waiver will depend on the 
intended use of the CEMS data (e.g., data collection purposes other than 
NSPS) and may require specifications more stringent than in Performance 
Specification 2 (e.g., the applicable emission limit is more stringent 
than NSPS).
    (2) The waiver of a CEMS RA test will be reviewed and may be 
rescinded at such time, following successful completion of the 
alternative RA procedure, that the CEMS data indicate that the source 
emissions are approaching the level. The criterion for reviewing the 
waiver is the collection of CEMS data showing that emissions have 
exceeded 70 percent of the applicable standard for seven, consecutive, 
averaging periods as specified by the applicable regulation(s). For 
sources subject

[[Page 69]]

to standards expressed as control efficiency levels, the criterion for 
reviewing the waiver is the collection of CEMS data showing that exhaust 
emissions have exceeded 70 percent of the level needed to meet the 
control efficiency requirement for seven, consecutive, averaging periods 
as specified by the applicable regulation(s) [e.g., Sec. Sec. 60.45(g) 
(2) and (3), 60.73(e), and 60.84(e)]. It is the responsibility of the 
source operator to maintain records and determine the level of emissions 
relative to the criterion on the waiver of RA testing. If this criterion 
is exceeded, the owner or operator must notify the Administrator within 
10 days of such occurrence and include a description of the nature and 
cause of the increasing emissions. The Administrator will review the 
notification and may rescind the waiver and require the owner or 
operator to conduct a RA test of the CEMS as specified in Section 8.4 of 
Performance Specification 2.

Sec. 60.14  Modification.

    (a) Except as provided under paragraphs (e) and (f) of this section, 
any physical or operational change to an existing facility which results 
in an increase in the emission rate to the atmosphere of any pollutant 
to which a standard applies shall be considered a modification within 
the meaning of section 111 of the Act. Upon modification, an existing 
facility shall become an affected facility for each pollutant to which a 
standard applies and for which there is an increase in the emission rate 
to the atmosphere.
    (b) Emission rate shall be expressed as kg/hr of any pollutant 
discharged into the atmosphere for which a standard is applicable. The 
Administrator shall use the following to determine emission rate:
    (1) Emission factors as specified in the latest issue of 
``Compilation of Air Pollutant Emission Factors,'' EPA Publication No. 
AP-42, or other emission factors determined by the Administrator to be 
superior to AP-42 emission factors, in cases where utilization of 
emission factors demonstrates that the emission level resulting from the 
physical or operational change will either clearly increase or clearly 
not increase.
    (2) Material balances, continuous monitor data, or manual emission 
tests in cases where utilization of emission factors as referenced in 
paragraph (b)(1) of this section does not demonstrate to the 
Administrator's satisfaction whether the emission level resulting from 
the physical or operational change will either clearly increase or 
clearly not increase, or where an owner or operator demonstrates to the 
Administrator's satisfaction that there are reasonable grounds to 
dispute the result obtained by the Administrator utilizing emission 
factors as referenced in paragraph (b)(1) of this section. When the 
emission rate is based on results from manual emission tests or 
continuous monitoring systems, the procedures specified in appendix C of 
this part shall be used to determine whether an increase in emission 
rate has occurred. Tests shall be conducted under such conditions as the 
Administrator shall specify to the owner or operator based on 
representative performance of the facility. At least three valid test 
runs must be conducted before and at least three after the physical or 
operational change. All operating parameters which may affect emissions 
must be held constant to the maximum feasible degree for all test runs.
    (c) The addition of an affected facility to a stationary source as 
an expansion to that source or as a replacement for an existing facility 
shall not by itself bring within the applicability of this part any 
other facility within that source.
    (d) [Reserved]
    (e) The following shall not, by themselves, be considered 
modifications under this part:
    (1) Maintenance, repair, and replacement which the Administrator 
determines to be routine for a source category, subject to the 
provisions of paragraph (c) of this section and Sec. 60.15.
    (2) An increase in production rate of an existing facility, if that 
increase

[[Page 70]]

can be accomplished without a capital expenditure on that facility.
    (3) An increase in the hours of operation.
    (4) Use of an alternative fuel or raw material if, prior to the date 
any standard under this part becomes applicable to that source type, as 
provided by Sec. 60.1, the existing facility was designed to 
accommodate that alternative use. A facility shall be considered to be 
designed to accommodate an alternative fuel or raw material if that use 
could be accomplished under the facility's construction specifications 
as amended prior to the change. Conversion to coal required for energy 
considerations, as specified in section 111(a)(8) of the Act, shall not 
be considered a modification.
    (5) The addition or use of any system or device whose primary 
function is the reduction of air pollutants, except when an emission 
control system is removed or is replaced by a system which the 
Administrator determines to be less environmentally beneficial.
    (6) The relocation or change in ownership of an existing facility.
    (f) Special provisions set forth under an applicable subpart of this 
part shall supersede any conflicting provisions of this section.
    (g) Within 180 days of the completion of any physical or operational 
change subject to the control measures specified in paragraph (a) of 
this section, compliance with all applicable standards must be achieved.
    (h) No physical change, or change in the method of operation, at an 
existing electric utility steam generating unit shall be treated as a 
modification for the purposes of this section provided that such change 
does not increase the maximum hourly emissions of any pollutant 
regulated under this section above the maximum hourly emissions 
achievable at that unit during the 5 years prior to the change.
    (i) Repowering projects that are awarded funding from the Department 
of Energy as permanent clean coal technology demonstration projects (or 
similar projects funded by EPA) are exempt from the requirements of this 
section provided that such change does not increase the maximum hourly 
emissions of any pollutant regulated under this section above the 
maximum hourly emissions achievable at that unit during the five years 
prior to the change.
    (j)(1) Repowering projects that qualify for an extension under 
section 409(b) of the Clean Air Act are exempt from the requirements of 
this section, provided that such change does not increase the actual 
hourly emissions of any pollutant regulated under this section above the 
actual hourly emissions achievable at that unit during the 5 years prior 
to the change.
    (2) This exemption shall not apply to any new unit that:
    (i) Is designated as a replacement for an existing unit;
    (ii) Qualifies under section 409(b) of the Clean Air Act for an 
extension of an emission limitation compliance date under section 405 of 
the Clean Air Act; and
    (iii) Is located at a different site than the existing unit.
    (k) The installation, operation, cessation, or removal of a 
temporary clean coal technology demonstration project is exempt from the 
requirements of this section. A temporary clean coal control technology 
demonstration project, for the purposes of this section is a clean coal 
technology demonstration project that is operated for a period of 5 
years or less, and which complies with the State implementation plan for 
the State in which the project is located and other requirements 
necessary to attain and maintain the national ambient air quality 
standards during the project and after it is terminated.
    (l) The reactivation of a very clean coal-fired electric utility 
steam generating unit is exempt from the requirements of this section.

Sec. 60.15  Reconstruction.

    (a) An existing facility, upon reconstruction, becomes an affected 
facility, irrespective of any change in emission rate.
    (b) ``Reconstruction'' means the replacement of components of an 
existing facility to such an extent that:

[[Page 71]]

    (1) The fixed capital cost of the new components exceeds 50 percent 
of the fixed capital cost that would be required to construct a 
comparable entirely new facility, and
    (2) It is technologically and economically feasible to meet the 
applicable standards set forth in this part.
    (c) ``Fixed capital cost'' means the capital needed to provide all 
the depreciable components.
    (d) If an owner or operator of an existing facility proposes to 
replace components, and the fixed capital cost of the new components 
exceeds 50 percent of the fixed capital cost that would be required to 
construct a comparable entirely new facility, he shall notify the 
Administrator of the proposed replacements. The notice must be 
postmarked 60 days (or as soon as practicable) before construction of 
the replacements is commenced and must include the following 
information:
    (1) Name and address of the owner or operator.
    (2) The location of the existing facility.
    (3) A brief description of the existing facility and the components 
which are to be replaced.
    (4) A description of the existing air pollution control equipment 
and the proposed air pollution control equipment.
    (5) An estimate of the fixed capital cost of the replacements and of 
constructing a comparable entirely new facility.
    (6) The estimated life of the existing facility after the 
replacements.
    (7) A discussion of any economic or technical limitations the 
facility may have in complying with the applicable standards of 
performance after the proposed replacements.
    (e) The Administrator will determine, within 30 days of the receipt 
of the notice required by paragraph (d) of this section and any 
additional information he may reasonably require, whether the proposed 
replacement constitutes reconstruction.
    (f) The Administrator's determination under paragraph (e) shall be 
based on:
    (1) The fixed capital cost of the replacements in comparison to the 
fixed capital cost that would be required to construct a comparable 
entirely new facility;
    (2) The estimated life of the facility after the replacements 
compared to the life of a comparable entirely new facility;
    (3) The extent to which the components being replaced cause or 
contribute to the emissions from the facility; and
    (4) Any economic or technical limitations on compliance with 
applicable standards of performance which are inherent in the proposed 
replacements.
    (g) Individual subparts of this part may include specific provisions 
which refine and delimit the concept of reconstruction set forth in this 
section.

practice used to identify leaking equipment. This alternative work 
practice is placed here for administrative convenience and is available 
to all subparts in 40 CFR parts 60, 61, 63, and 65 that require 
monitoring of equipment with a 40 CFR part 60, appendix A-7, Method 21 
monitor.
    (b) Flares. Paragraphs (c) through (f) apply to flares.
    (c)(1) Flares shall be designed for and operated with no visible 
emissions as determined by the methods specified in paragraph (f), 
except for periods not to exceed a total of 5 minutes during any 2 
consecutive hours.
    (2) Flares shall be operated with a flame present at all times, as 
determined by the methods specified in paragraph (f).
    (3) An owner/operator has the choice of adhering to either the heat 
content specifications in paragraph (c)(3)(ii) of this section and the 
maximum tip velocity specifications in paragraph (c)(4) of this section, 
or adhering to the requirements in paragraph (c)(3)(i) of this section.
    (i)(A) Flares shall be used that have a diameter of 3 inches or 
greater, are nonassisted, have a hydrogen content of 8.0 percent (by 
volume), or greater, and are designed for and operated with an exit 
velocity less than 37.2 m/sec (122 ft/sec) and less than the velocity, 
Vmax, as determined by the following equation:

Vmax = (XH2-K1)* K2

Where:

Vmax = Maximum permitted velocity, m/sec.
K1 = Constant, 6.0 volume-percent hydrogen.
K2 = Constant, 3.9(m/sec)/volume-percent hydrogen.
XH2 = The volume-percent of hydrogen, on a wet basis, as 
          calculated by using the American Society for Testing and 
          Materials (ASTM) Method D1946-77. (Incorporated by reference 
          as specified in Sec. 60.17).

    (B) The actual exit velocity of a flare shall be determined by the 
method specified in paragraph (f)(4) of this section.
    (ii) Flares shall be used only with the net heating value of the gas 
being combusted being 11.2 MJ/scm (300 Btu/scf) or greater if the flare 
is steam-assisted or air-assisted; or with the net heating value of the 
gas being combusted being 7.45 MJ/scm (200 Btu/scf) or greater if the 
flare is nonassisted. The net heating value of the gas being combusted 
shall be determined by the methods specified in paragraph (f)(3) of this 
section.
    (4)(i) Steam-assisted and nonassisted flares shall be designed for 
and operated with an exit velocity, as determined by the methods 
specified in paragraph (f)(4) of this section, less than 18.3 m/sec (60 
ft/sec), except as provided in paragraphs (c)(4) (ii) and (iii) of this 
section.
    (ii) Steam-assisted and nonassisted flares designed for and operated 
with an exit velocity, as determined by the methods specified in 
paragraph (f)(4), equal to or greater than 18.3 m/sec (60 ft/sec) but 
less than 122 m/sec (400 ft/sec) are allowed if the net heating value of 
the gas being combusted is greater than 37.3 MJ/scm (1,000 Btu/scf).
    (iii) Steam-assisted and nonassisted flares designed for and 
operated with an exit velocity, as determined by the methods specified 
in paragraph (f)(4),

[[Page 87]]

less than the velocity, Vmax, as determined by the method 
specified in paragraph (f)(5), and less than 122 m/sec (400 ft/sec) are 
allowed.
    (5) Air-assisted flares shall be designed and operated with an exit 
velocity less than the velocity, Vmax, as determined by the 
method specified in paragraph (f)(6).
    (6) Flares used to comply with this section shall be steam-assisted, 
air-assisted, or nonassisted.
    (d) Owners or operators of flares used to comply with the provisions 
of this subpart shall monitor these control devices to ensure that they 
are operated and maintained in conformance with their designs. 
Applicable subparts will provide provisions stating how owners or 
operators of flares shall monitor these control devices.
    (e) Flares used to comply with provisions of this subpart shall be 
operated at all times when emissions may be vented to them.
    (f)(1) Method 22 of appendix A to this part shall be used to 
determine the compliance of flares with the visible emission provisions 
of this subpart. The observation period is 2 hours and shall be used 
according to Method 22.
    (2) The presence of a flare pilot flame shall be monitored using a 
thermocouple or any other equivalent device to detect the presence of a 
flame.
    (3) The net heating value of the gas being combusted in a flare 
shall be calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.008

where:

HT = Net heating value of the sample, MJ/scm; where the net 
          enthalpy per mole of offgas is based on combustion at 25 
          [deg]C and 760 mm Hg, but the standard temperature for 
          determining the volume corresponding to one mole is 20 [deg]C;
          [GRAPHIC] [TIFF OMITTED] TC01JN92.009
          
Ci = Concentration of sample component i in ppm on a wet 
          basis, as measured for organics by Reference Method 18 and 
          measured for hydrogen and carbon monoxide by ASTM D1946-77 or 
          90 (Reapproved 1994) (Incorporated by reference as specified 
          in Sec. 60.17); and
Hi = Net heat of combustion of sample component i, kcal/g 
          mole at 25 [deg]C and 760 mm Hg. The heats of combustion may 
          be determined using ASTM D2382-76 or 88 or D4809-95 
          (incorporated by reference as specified in Sec. 60.17) if 
          published values are not available or cannot be calculated.

    (4) The actual exit velocity of a flare shall be determined by 
dividing the volumetric flowrate (in units of standard temperature and 
pressure), as determined by Reference Methods 2, 2A, 2C, or 2D as 
appropriate; by the unobstructed (free) cross sectional area of the 
flare tip.
    (5) The maximum permitted velocity, Vmax, for flares 
complying with paragraph (c)(4)(iii) shall be determined by the 
following equation.
Log10 (Vmax) = (HT + 28.8)/31.7

Vmax = Maximum permitted velocity, M/sec
28.8 = Constant
31.7 = Constant
HT = The net heating value as determined in paragraph (f)(3).

    (6) The maximum permitted velocity, Vmax, for air-
assisted flares shall be determined by the following equation.
Vmax = 8.706 + 0.7084 (HT)

Vmax = Maximum permitted velocity, m/sec
8.706 = Constant
0.7084 = Constant
HT = The net heating value as determined in paragraph (f)(3).
    (g) Alternative work practice for monitoring equipment for leaks. 
Paragraphs (g), (h), and (i) of this section apply to all equipment for 
which the applicable subpart requires monitoring with a 40 CFR part 60, 
appendix A-7, Method 21

[[Page 88]]

monitor, except for closed vent systems, equipment designated as 
leakless, and equipment identified in the applicable subpart as having 
no detectable emissions, as indicated by an instrument reading of less 
than 500 ppm above background. An owner or operator may use an optical 
gas imaging instrument instead of a 40 CFR part 60, appendix A-7, Method 
21 monitor. Requirements in the existing subparts that are specific to 
the Method 21 instrument do not apply under this section. All other 
requirements in the applicable subpart that are not addressed in 
paragraphs (g), (h), and (i) of this section apply to this standard. For 
example, equipment specification requirements, and non-Method 21 
instrument recordkeeping and reporting requirements in the applicable 
subpart continue to apply. The terms defined in paragraphs (g)(1) 
through (5) of this section have meanings that are specific to the 
alternative work practice standard in paragraphs (g), (h), and (i) of 
this section.
    (1) Applicable subpart means the subpart in 40 CFR parts 60, 61, 63, 
or 65 that requires monitoring of equipment with a 40 CFR part 60, 
appendix A-7, Method 21 monitor.
    (2) Equipment means pumps, valves, pressure relief valves, 
compressors, open-ended lines, flanges, connectors, and other equipment 
covered by the applicable subpart that require monitoring with a 40 CFR 
part 60, appendix A-7, Method 21 monitor.
    (3) Imaging means making visible emissions that may otherwise be 
invisible to the naked eye.
    (4) Optical gas imaging instrument means an instrument that makes 
visible emissions that may otherwise be invisible to the naked eye.
    (5) Repair means that equipment is adjusted, or otherwise altered, 
in order to eliminate a leak.
    (6) Leak means:
    (i) Any emissions imaged by the optical gas instrument;
    (ii) Indications of liquids dripping;
    (iii) Indications by a sensor that a seal or barrier fluid system 
has failed; or
    (iv) Screening results using a 40 CFR part 60, appendix A-7, Method 
21 monitor that exceed the leak definition in the applicable subpart to 
which the equipment is subject.
    (h) The alternative work practice standard for monitoring equipment 
for leaks is available to all subparts in 40 CFR parts 60, 61, 63, and 
65 that require monitoring of equipment with a 40 CFR part 60, appendix 
A-7, Method 21 monitor.
    (1) An owner or operator of an affected source subject to CFR parts 
60, 61, 63, or 65 can choose to comply with the alternative work 
practice requirements in paragraph (i) of this section instead of using 
the 40 CFR part 60, appendix A-7, Method 21 monitor to identify leaking 
equipment. The owner or operator must document the equipment, process 
units, and facilities for which the alternative work practice will be 
used to identify leaks.
    (2) Any leak detected when following the leak survey procedure in 
paragraph (i)(3) of this section must be identified for repair as 
required in the applicable subpart.
    (3) If the alternative work practice is used to identify leaks, re-
screening after an attempted repair of leaking equipment must be 
conducted using either the alternative work practice or the 40 CFR part 
60, appendix A-7, Method 21 monitor at the leak definition required in 
the applicable subpart to which the equipment is subject.
    (4) The schedule for repair is as required in the applicable 
subpart.
    (5) When this alternative work practice is used for detecting 
leaking equipment, choose one of the monitoring frequencies listed in 
Table 1 to subpart A of this part in lieu of the monitoring frequency 
specified for regulated equipment in the applicable subpart. Reduced 
monitoring frequencies for good performance are not applicable when 
using the alternative work practice.
    (6) When this alternative work practice is used for detecting 
leaking equipment the following are not applicable for the equipment 
being monitored:
    (i) Skip period leak detection and repair;
    (ii) Quality improvement plans; or
    (iii) Complying with standards for allowable percentage of valves 
and pumps to leak.

[[Page 89]]

    (7) When the alternative work practice is used to detect leaking 
equipment, the regulated equipment in paragraph (h)(1)(i) of this 
section must also be monitored annually using a 40 CFR part 60, appendix 
A-7, Method 21 monitor at the leak definition required in the applicable 
subpart. The owner or operator may choose the specific monitoring period 
(for example, first quarter) to conduct the annual monitoring. 
Subsequent monitoring must be conducted every 12 months from the initial 
period. Owners or operators must keep records of the annual Method 21 
screening results, as specified in paragraph (i)(4)(vii) of this 
section.
    (i) An owner or operator of an affected source who chooses to use 
the alternative work practice must comply with the requirements of 
paragraphs (i)(1) through (i)(5) of this section.
    (1) Instrument Specifications. The optical gas imaging instrument 
must comply with the requirements in (i)(1)(i) and (i)(1)(ii) of this 
section.
    (i) Provide the operator with an image of the potential leak points 
for each piece of equipment at both the detection sensitivity level and 
within the distance used in the daily instrument check described in 
paragraph (i)(2) of this section. The detection sensitivity level 
depends upon the frequency at which leak monitoring is to be performed.
    (ii) Provide a date and time stamp for video records of every 
monitoring event.
    (2) Daily Instrument Check. On a daily basis, and prior to beginning 
any leak monitoring work, test the optical gas imaging instrument at the 
mass flow rate determined in paragraph (i)(2)(i) of this section in 
accordance with the procedure specified in paragraphs (i)(2)(ii) through 
(i)(2)(iv) of this section for each camera configuration used during 
monitoring (for example, different lenses used), unless an alternative 
method to demonstrate daily instrument checks has been approved in 
accordance with paragraph (i)(2)(v) of this section.
    (i) Calculate the mass flow rate to be used in the daily instrument 
check by following the procedures in paragraphs (i)(2)(i)(A) and 
(i)(2)(i)(B) of this section.
    (A) For a specified population of equipment to be imaged by the 
instrument, determine the piece of equipment in contact with the lowest 
mass fraction of chemicals that are detectable, within the distance to 
be used in paragraph (i)(2)(iv)(B) of this section, at or below the 
standard detection sensitivity level.
    (B) Multiply the standard detection sensitivity level, corresponding 
to the selected monitoring frequency in Table 1 of subpart A of this 
part, by the mass fraction of detectable chemicals from the stream 
identified in paragraph (i)(2)(i)(A) of this section to determine the 
mass flow rate to be used in the daily instrument check, using the 
following equation.
[GRAPHIC] [TIFF OMITTED] TR22DE08.007

Where:

Edic = Mass flow rate for the daily instrument check, grams 
          per hour
xi = Mass fraction of detectable chemical(s) i seen by the 
          optical gas imaging instrument, within the distance to be used 
          in paragraph (i)(2)(iv)(B) of this section, at or below the 
          standard detection sensitivity level, Esds.
Esds = Standard detection sensitivity level from Table 1 to 
          subpart A, grams per hour
k = Total number of detectable chemicals emitted from the leaking 
          equipment and seen by the optical gas imaging instrument.

    (ii) Start the optical gas imaging instrument according to the 
manufacturer's instructions, ensuring that all appropriate settings 
conform to the manufacturer's instructions.
    (iii) Use any gas chosen by the user that can be viewed by the 
optical gas imaging instrument and that has a purity of no less than 98 
percent.
    (iv) Establish a mass flow rate by using the following procedures:
    (A) Provide a source of gas where it will be in the field of view of 
the optical gas imaging instrument.
    (B) Set up the optical gas imaging instrument at a recorded distance 
from the outlet or leak orifice of the flow meter that will not be 
exceeded in the actual performance of the leak survey. Do not exceed the 
operating parameters of the flow meter.

[[Page 90]]

    (C) Open the valve on the flow meter to set a flow rate that will 
create a mass emission rate equal to the mass rate specified in 
paragraph (i)(2)(i) of this section while observing the gas flow through 
the optical gas imaging instrument viewfinder. When an image of the gas 
emission is seen through the viewfinder at the required emission rate, 
make a record of the reading on the flow meter.
    (v) Repeat the procedures specified in paragraphs (i)(2)(ii) through 
(i)(2)(iv) of this section for each configuration of the optical gas 
imaging instrument used during the leak survey.
    (vi) To use an alternative method to demonstrate daily instrument 
checks, apply to the Administrator for approval of the alternative under 
Sec. 60.13(i).
    (3) Leak Survey Procedure. Operate the optical gas imaging 
instrument to image every regulated piece of equipment selected for this 
work practice in accordance with the instrument manufacturer's operating 
parameters. All emissions imaged by the optical gas imaging instrument 
are considered to be leaks and are subject to repair. All emissions 
visible to the naked eye are also considered to be leaks and are subject 
to repair.
    (4) Recordkeeping. You must keep the records described in paragraphs 
(i)(4)(i) through (i)(4)(vii) of this section:
    (i) The equipment, processes, and facilities for which the owner or 
operator chooses to use the alternative work practice.
    (ii) The detection sensitivity level selected from Table 1 to 
subpart A of this part for the optical gas imaging instrument.
    (iii) The analysis to determine the piece of equipment in contact 
with the lowest mass fraction of chemicals that are detectable, as 
specified in paragraph (i)(2)(i)(A) of this section.
    (iv) The technical basis for the mass fraction of detectable 
chemicals used in the equation in paragraph (i)(2)(i)(B) of this 
section.
    (v) The daily instrument check. Record the distance, per paragraph 
(i)(2)(iv)(B) of this section, and the flow meter reading, per paragraph 
(i)(2)(iv)(C) of this section, at which the leak was imaged. Keep a 
video record of the daily instrument check for each configuration of the 
optical gas imaging instrument used during the leak survey (for example, 
the daily instrument check must be conducted for each lens used). The 
video record must include a time and date stamp for each daily 
instrument check. The video record must be kept for 5 years.
    (vi) Recordkeeping requirements in the applicable subpart. A video 
record must be used to document the leak survey results. The video 
record must include a time and date stamp for each monitoring event. A 
video record can be used to meet the recordkeeping requirements of the 
applicable subparts if each piece of regulated equipment selected for 
this work practice can be identified in the video record. The video 
record must be kept for 5 years.
    (vii) The results of the annual Method 21 screening required in 
paragraph (h)(7) of this section. Records must be kept for all regulated 
equipment specified in paragraph (h)(1) of this section. Records must 
identify the equipment screened, the screening value measured by Method 
21, the time and date of the screening, and calibration information 
required in the existing applicable subpart.
    (5) Reporting. Submit the reports required in the applicable 
subpart. Submit the records of the annual Method 21 screening required 
in paragraph (h)(7) of this section to the Administrator via e-mail to 
[email protected].

Sec. 60.19  General notification and reporting requirements.

    (a) For the purposes of this part, time periods specified in days 
shall be measured in calendar days, even if the word ``calendar'' is 
absent, unless otherwise specified in an applicable requirement.
    (b) For the purposes of this part, if an explicit postmark deadline 
is not specified in an applicable requirement for the submittal of a 
notification, application, report, or other written communication to the 
Administrator, the owner or operator shall postmark the

[[Page 91]]

submittal on or before the number of days specified in the applicable 
requirement. For example, if a notification must be submitted 15 days 
before a particular event is scheduled to take place, the notification 
shall be postmarked on or before 15 days preceding the event; likewise, 
if a notification must be submitted 15 days after a particular event 
takes place, the notification shall be delivered or postmarked on or 
before 15 days following the end of the event. The use of reliable non-
Government mail carriers that provide indications of verifiable delivery 
of information required to be submitted to the Administrator, similar to 
the postmark provided by the U.S. Postal Service, or alternative means 
of delivery, including the use of electronic media, agreed to by the 
permitting authority, is acceptable.
    (c) Notwithstanding time periods or postmark deadlines specified in 
this part for the submittal of information to the Administrator by an 
owner or operator, or the review of such information by the 
Administrator, such time periods or deadlines may be changed by mutual 
agreement between the owner or operator and the Administrator. 
Procedures governing the implementation of this provision are specified 
in paragraph (f) of this section.
    (d) If an owner or operator of an affected facility in a State with 
delegated authority is required to submit periodic reports under this 
part to the State, and if the State has an established timeline for the 
submission of periodic reports that is consistent with the reporting 
frequency(ies) specified for such facility under this part, the owner or 
operator may change the dates by which periodic reports under this part 
shall be submitted (without changing the frequency of reporting) to be 
consistent with the State's schedule by mutual agreement between the 
owner or operator and the State. The allowance in the previous sentence 
applies in each State beginning 1 year after the affected facility is 
required to be in compliance with the applicable subpart in this part. 
Procedures governing the implementation of this provision are specified 
in paragraph (f) of this section.
    (e) If an owner or operator supervises one or more stationary 
sources affected by standards set under this part and standards set 
under part 61, part 63, or both such parts of this chapter, he/she may 
arrange by mutual agreement between the owner or operator and the 
Administrator (or the State with an approved permit program) a common 
schedule on which periodic reports required by each applicable standard 
shall be submitted throughout the year. The allowance in the previous 
sentence applies in each State beginning 1 year after the stationary 
source is required to be in compliance with the applicable subpart in 
this part, or 1 year after the stationary source is required to be in 
compliance with the applicable 40 CFR part 61 or part 63 of this chapter 
standard, whichever is latest. Procedures governing the implementation 
of this provision are specified in paragraph (f) of this section.
    (f)(1)(i) Until an adjustment of a time period or postmark deadline 
has been approved by the Administrator under paragraphs (f)(2) and 
(f)(3) of this section, the owner or operator of an affected facility 
remains strictly subject to the requirements of this part.
    (ii) An owner or operator shall request the adjustment provided for 
in paragraphs (f)(2) and (f)(3) of this section each time he or she 
wishes to change an applicable time period or postmark deadline 
specified in this part.
    (2) Notwithstanding time periods or postmark deadlines specified in 
this part for the submittal of information to the Administrator by an 
owner or operator, or the review of such information by the 
Administrator, such time periods or deadlines may be changed by mutual 
agreement between the owner or operator and the Administrator. An owner 
or operator who wishes to request a change in a time period or postmark 
deadline for a particular requirement shall request the adjustment in 
writing as soon as practicable before the subject activity is required 
to take place. The owner or operator shall include in the request 
whatever information he or she considers useful to convince the 
Administrator that an adjustment is warranted.

[[Page 92]]

    (3) If, in the Administrator's judgment, an owner or operator's 
request for an adjustment to a particular time period or postmark 
deadline is warranted, the Administrator will approve the adjustment. 
The Administrator will notify the owner or operator in writing of 
approval or disapproval of the request for an adjustment within 15 
calendar days of receiving sufficient information to evaluate the 
request.
    (4) If the Administrator is unable to meet a specified deadline, he 
or she will notify the owner or operator of any significant delay and 
inform the owner or operator of the amended schedule.

    Terms used but not defined in this subpart shall have the meaning 
given them in the Act and in subpart A:
    (a) Designated pollutant means any air pollutant, the emissions of 
which are subject to a standard of performance for new stationary 
sources, but for which air quality criteria have not been issued and 
that is not included on a list published under section 108(a) or section 
112(b)(1)(A) of the Act.
    (b) Designated facility means any existing facility (see Sec. 
60.2(aa)) which emits a designated pollutant and which would be subject 
to a standard of performance for that pollutant if the existing facility 
were an affected facility (see Sec. 60.2(e)).
    (c) Plan means a plan under section 111(d) of the Act which 
establishes emission standards for designated pollutants from designated 
facilities and provides for the implementation and enforcement of such 
emission standards.
    (d) Applicable plan means the plan, or most recent revision thereof, 
which has been approved under Sec. 60.27(b) or promulgated under Sec. 
60.27(d).
    (e) Emission guideline means a guideline set forth in subpart C of 
this part, or in a final guideline document published under Sec. 
60.22(a), which reflects the degree of emission reduction achievable 
through the application of the best system of emission reduction which 
(taking into account the cost of such reduction) the Administrator has 
determined has been adequately demonstrated for designated facilities.
    (f) Emission standard means a legally enforceable regulation setting 
forth an allowable rate of emissions into the atmosphere, establishing 
an allowance system, or prescribing equipment specifications for control 
of air pollution emissions.
    (g) Compliance schedule means a legally enforceable schedule 
specifying a date or dates by which a source or category of sources must 
comply with specific emission standards contained in a plan or with any 
increments of progress to achieve such compliance.
    (h) Increments of progress means steps to achieve compliance which 
must be taken by an owner or operator of a designated facility, 
including:
    (1) Submittal of a final control plan for the designated facility to 
the appropriate air pollution control agency;
    (2) Awarding of contracts for emission control systems or for 
process modifications, or issuance of orders for the purchase of 
component parts to accomplish emission control or process modification;

[[Page 93]]

    (3) Initiation of on-site construction or installation of emission 
control equipment or process change;

FR 9447, Feb. 16, 2012]



Sec. 60.22  Publication of guideline documents, emission guidelines,
and final compliance times.

    (a) Concurrently upon or after proposal of standards of performance 
for the control of a designated pollutant from affected facilities, the 
Administrator will publish a draft guideline document containing 
information pertinent to control of the designated pollutant form 
designated facilities. Notice of the availability of the draft guideline 
document will be published in the Federal Register and public comments 
on its contents will be invited. After consideration of public comments 
and upon or after promulgation of standards of performance for control 
of a designated pollutant from affected facilities, a final guideline 
document will be published and notice of its availability will be 
published in the Federal Register.
    (b) Guideline documents published under this section will provide 
information for the development of State plans, such as:
    (1) Information concerning known or suspected endangerment of public 
health or welfare caused, or contributed to, by the designated 
pollutant.
    (2) A description of systems of emission reduction which, in the 
judgment of the Administrator, have been adequately demonstrated.
    (3) Information on the degree of emission reduction which is 
achievable with each system, together with information on the costs and 
environmental effects of applying each system to designated facilities.
    (4) Incremental periods of time normally expected to be necessary 
for the design, installation, and startup of identified control systems.
    (5) An emission guideline that reflects the application of the best 
system of emission reduction (considering the cost of such reduction) 
that has been adequately demonstrated for designated facilities, and the 
time within which compliance with emission standards of equivalent 
stringency can be achieved. The Administrator will specify different 
emission guidelines or compliance times or both for different sizes, 
types, and classes of designated facilities when costs of control, 
physical limitations, geographical location, or similar factors make 
subcategorization appropriate. (6) Such other available information as 
the Administrator determines may contribute to the formulation of State 
plans.
    (c) Except as provided in paragraph (d)(1) of this section, the 
emission guidelines and compliance times referred to in paragraph (b)(5) 
of this section will be proposed for comment upon publication of the 
draft guideline document, and after consideration of comments will be 
promulgated in subpart C of this part with such modifications as may be 
appropriate.
    (d)(1) If the Administrator determines that a designated pollutant 
may cause or contribute to endangerment of public welfare, but that 
adverse effects on public health have not been demonstrated, he will 
include the determination in the draft guideline document and in the 
Federal Register notice of its availability. Except as provided in 
paragraph (d)(2) of this section, paragraph (c) of this section shall be 
inapplicable in such cases.
    (2) If the Administrator determines at any time on the basis of new 
information that a prior determination under paragraph (d)(1) of this 
section is incorrect or no longer correct, he will publish notice of the 
determination in the Federal Register, revise the guideline document as 
necessary under paragraph (a) of this section, and propose and 
promulgate emission guidelines and compliance times under paragraph (c) 
of this section.

Sec. 60.23  Adoption and submittal of State plans; public hearings.

    (a)(1) Unless otherwise specified in the applicable subpart, within 
9 months after notice of the availability of a final guideline document 
is published under Sec. 60.22(a), each State shall adopt and submit to 
the Administrator, in accordance with Sec. 60.4 of subpart A of this 
part, a plan for the control of the designated pollutant to which the 
guideline document applies.
    (2) Within nine months after notice of the availability of a final 
revised guideline document is published as provided in Sec. 
60.22(d)(2), each State shall adopt and submit to the Administrator any 
plan revision necessary to meet the requirements of this subpart.
    (b) If no designated facility is located within a State, the State 
shall submit a letter of certification to that effect to the 
Administrator within the time specified in paragraph (a) of this 
section. Such certification shall exempt the State from the requirements 
of this subpart for that designated pollutant.
    (c)(1) Except as provided in paragraphs (c)(2) and (c)(3) of this 
section, the State shall, prior to the adoption of any plan or revision 
thereof, conduct one or more public hearings within the State on such 
plan or plan revision.
    (2) No hearing shall be required for any change to an increment of 
progress in an approved compliance schedule unless the change is likely 
to cause the facility to be unable to comply with the final compliance 
date in the schedule.
    (3) No hearing shall be required on an emission standard in effect 
prior to the effective date of this subpart if it was adopted after a 
public hearing and is at least as stringent as the corresponding 
emission guideline specified in the applicable guideline document 
published under Sec. 60.22(a).
    (d) Any hearing required by paragraph (c) of this section shall be 
held only after reasonable notice. Notice shall be given at least 30 
days prior to the date of such hearing and shall include:
    (1) Notification to the public by prominently advertising the date, 
time, and place of such hearing in each region affected;
    (2) Availability, at the time of public announcement, of each 
proposed plan or revision thereof for public inspection in at least one 
location in each region to which it will apply;
    (3) Notification to the Administrator;
    (4) Notification to each local air pollution control agency in each 
region to which the plan or revision will apply; and
    (5) In the case of an interstate region, notification to any other 
State included in the region.
    (e) The State shall prepare and retain, for a minimum of 2 years, a 
record of each hearing for inspection by any interested party. The 
record shall contain, as a minimum, a list of witnesses together with 
the text of each presentation.
    (f) The State shall submit with the plan or revision:
    (1) Certification that each hearing required by paragraph (c) of 
this section was held in accordance with the notice required by 
paragraph (d) of this section; and
    (2) A list of witnesses and their organizational affiliations, if 
any, appearing at the hearing and a brief written summary of each 
presentation or written submission.
    (g) Upon written application by a State agency (through the 
appropriate Regional Office), the Administrator may approve State 
procedures designed to insure public participation in the matters for 
which hearings are required and public notification of the opportunity 
to participate if, in the judgment of the Administrator, the procedures, 
although different from the requirements of this subpart, in fact 
provide for adequate notice to and participation of the public. The 
Administrator may impose such conditions on his approval as he deems 
necessary. Procedures approved under this section shall be deemed to 
satisfy the requirements of this subpart regarding procedures for public 
hearings.

Sec. 60.24  Emission standards and compliance schedules.

    (a) Each plan shall include emission standards and compliance 
schedules.

[[Page 95]]

    (b) (1) Emission standards shall either be based on an allowance 
system or prescribe allowable rates of emissions except when it is 
clearly impracticable. Such cases will be identified in the guideline 
documents issued under Sec. 60.22. Where emission standards prescribing 
equipment specifications are established, the plan shall, to the degree 
possible, set forth the emission reductions achievable by implementation 
of such specifications, and may permit compliance by the use of 
equipment determined by the State to be equivalent to that prescribed.
    (2) Test methods and procedures for determining compliance with the 
emission standards shall be specified in the plan. Methods other than 
those specified in appendix A to this part may be specified in the plan 
if shown to be equivalent or alternative methods as defined in Sec. 
60.2 (t) and (u).
    (3) Emission standards shall apply to all designated facilities 
within the State. A plan may contain emission standards adopted by local 
jurisdictions provided that the standards are enforceable by the State.
    (c) Except as provided in paragraph (f) of this section, where the 
Administrator has determined that a designated pollutant may cause or 
contribute to endangerment of public health, emission standards shall be 
no less stringent than the corresponding emission guideline(s) specified 
in subpart C of this part, and final compliance shall be required as 
expeditiously as practicable but no later than the compliance times 
specified in subpart C of this part.
    (d) Where the Administrator has determined that a designated 
pollutant may cause or contribute to endangerment of public welfare but 
that adverse effects on public health have not been demonstrated, States 
may balance the emission guidelines, compliance times, and other 
information provided in the applicable guideline document against other 
factors of public concern in establishing emission standards, compliance 
schedules, and variances. Appropriate consideration shall be given to 
the factors specified in Sec. 60.22(b) and to information presented at 
the public hearing(s) conducted under Sec. 60.23(c).
    (e)(1) Any compliance schedule extending more than 12 months from 
the date required for submittal of the plan must include legally 
enforceable increments of progress to achieve compliance for each 
designated facility or category of facilities. Unless otherwise 
specified in the applicable subpart, increments of progress must 
include, where practicable, each increment of progress specified in 
Sec. 60.21(h) and must include such additional increments of progress 
as may be necessary to permit close and effective supervision of 
progress toward final compliance.
    (2) A plan may provide that compliance schedules for individual 
sources or categories of sources will be formulated after plan 
submittal. Any such schedule shall be the subject of a public hearing 
held according to Sec. 60.23 and shall be submitted to the 
Administrator within 60 days after the date of adoption of the schedule 
but in no case later than the date prescribed for submittal of the first 
semiannual report required by Sec. 60.25(e).
    (f) Unless otherwise specified in the applicable subpart on a case-
by-case basis for particular designated facilities or classes of 
facilities, States may provide for the application of less stringent 
emissions standards or longer compliance schedules than those otherwise 
required by paragraph (c) of this section, provided that the State 
demonstrates with respect to each such facility (or class of 
facilities):
    (1) Unreasonable cost of control resulting from plant age, location, 
or basic process design;
    (2) Physical impossibility of installing necessary control 
equipment; or
    (3) Other factors specific to the facility (or class of facilities) 
that make application of a less stringent standard or final compliance 
time significantly more reasonable.
    (g) Nothing in this subpart shall be construed to preclude any State 
or political subdivision thereof from adopting or enforcing (1) emission 
standards more stringent than emission guidelines specified in subpart C 
of this part or in applicable guideline documents or (2) compliance 
schedules requiring final compliance at earlier times than

[[Page 96]]

those specified in subpart C or in applicable guideline documents.

the State has adopted and submitted a plan or plan revision which the 
Administrator determines to be approvable.
    (e)(1) Except as provided in paragraph (e)(2) of this section, 
regulations proposed and promulgated by the Administrator under this 
section will prescribe emission standards of the same stringency as the 
corresponding emission guideline(s) specified in the final guideline 
document published under Sec. 60.22(a) and will require final 
compliance with such standards as expeditiously as

[[Page 98]]

practicable but no later than the times specified in the guideline 
document.
    (2) Upon application by the owner or operator of a designated 
facility to which regulations proposed and promulgated under this 
section will apply, the Administrator may provide for the application of 
less stringent emission standards or longer compliance schedules than

been issued and that is not included on a list published under section 
108(a) or section 112(b)(1)(A) of the Act.
    (b) Designated facility means any existing facility (see Sec. 60.2) 
which emits a designated pollutant and which would be subject to a 
standard of performance for that pollutant if the existing facility were 
an affected facility (see Sec. 60.2).
    (c) Plan means a plan under section 111(d) of the Act which 
establishes standards of performance for designated pollutants from 
designated facilities and provides for the implementation and

which has been approved under Sec. 60.27a(b) or promulgated under Sec. 
60.27a(d).
    (e) Emission guideline means a guideline set forth in subpart C of 
this part, or in a final guideline document published under Sec. 
60.22a(a), which reflects the degree of emission limitation achievable 
through the application of the best system of emission reduction which 
(taking into account the cost of such reduction and any non-air quality 
health and environmental impact and energy requirements) the 
Administrator has determined has been adequately demonstrated for 
designated facilities.
    (f) Standard of performance means a standard for emissions of air 
pollutants which reflects the degree of emission limitation achievable 
through the application of the best system of emission reduction which 
(taking into account the cost of achieving such reduction and any nonair 
quality health and environmental impact and energy requirements) the 
Administrator determines has been adequately demonstrated, including, 
but not limited to a legally enforceable regulation setting forth an 
allowable rate or limit of emissions into the atmosphere, or prescribing 
a design, equipment, work practice, or operational standard, or 
combination thereof.
    (g) Compliance schedule means a legally enforceable schedule 
specifying a date or dates by which a source or category of sources must 
comply with specific standards of performance contained in a plan or 
with any increments of progress to achieve such compliance.
    (h) Increments of progress means steps to achieve compliance which 
must be taken by an owner or operator of a designated facility, 
including:
    (1) Submittal of a final control plan for the designated facility to 
the appropriate air pollution control agency;
    (2) Awarding of contracts for emission control systems or for 
process modifications, or issuance of orders for the purchase of 
component parts to accomplish emission control or process modification;

Sec. 60.22a  Publication of emission guidelines.

    (a) Concurrently upon or after proposal of standards of performance 
for the control of a designated pollutant from affected facilities, the 
Administrator will publish a draft emission guideline containing 
information pertinent to control of the designated pollutant from 
designated facilities. Notice of the availability of the draft emission 
guideline will be published in the Federal Register and public comments 
on its contents will be invited. After consideration of public comments 
and upon or after promulgation of standards of performance for control 
of a designated pollutant from affected facilities, a final emission 
guideline will be published and notice of its availability will be 
published in the Federal Register.
    (b) Emission guidelines published under this section will provide 
information for the development of State plans, such as:
    (1) Information concerning known or suspected endangerment of public 
health or welfare caused, or contributed to, by the designated 
pollutant.

[[Page 100]]

    (2) A description of systems of emission reduction which, in the 
judgment of the Administrator, have been adequately demonstrated.
    (3) Information on the degree of emission limitation which is 
achievable with each system, together with information on the costs, 
nonair quality health environmental effects, and energy requirements of 
applying each system to designated facilities.
    (4) Incremental periods of time normally expected to be necessary 
for the design, installation, and startup of identified control systems.
    (5) The degree of emission limitation achievable through the 
application of the best system of emission reduction (considering the 
cost of such achieving reduction and any nonair quality health and 
environmental impact and energy requirements) that has been adequately 
demonstrated for designated facilities, and the time within which 
compliance with standards of performance can be achieved. The 
Administrator may specify different degrees of emission limitation or 
compliance times or both for different sizes, types, and classes of 
designated facilities when costs of control, physical limitations, 
geographical location, or similar factors make subcategorization 
appropriate.
    (6) Such other available information as the Administrator determines 
may contribute to the formulation of State plans.
    (c) The emission guidelines and compliance times referred to in 
paragraph (b)(5) of this section will be proposed for comment upon 
publication of the draft guideline document, and after consideration of 
comments will be promulgated in subpart C of this part with such 
modifications as may be appropriate.



Sec. 60.23a  Adoption and submittal of State plans; public hearings.

    (a)(1) Unless otherwise specified in the applicable subpart, within 
three years after notice of the availability of a final emission 
guideline is published under Sec. 60.22a(a), each State shall adopt and 
submit to the Administrator, in accordance with Sec. 60.4, a plan for 
the control of the designated pollutant to which the emission guideline 
applies.
    (2) At any time, each State may adopt and submit to the 
Administrator any plan revision necessary to meet the requirements of 
this subpart or an applicable subpart of this part.
    (b) If no designated facility is located within a State, the State 
shall submit a letter of certification to that effect to the 
Administrator within the time specified in paragraph (a) of this 
section. Such certification shall exempt the State from the requirements 
of this subpart for that designated pollutant.
    (c) The State shall, prior to the adoption of any plan or revision 
thereof, conduct one or more public hearings within the State on such 
plan or plan revision in accordance with the provisions under this 
section.
    (d) Any hearing required by paragraph (c) of this section shall be 
held only after reasonable notice. Notice shall be given at least 30 
days prior to the date of such hearing and shall include:
    (1) Notification to the public by prominently advertising the date, 
time, and place of such hearing in each region affected. This 
requirement may be satisfied by advertisement on the internet;
    (2) Availability, at the time of public announcement, of each 
proposed plan or revision thereof for public inspection in at least one 
location in each region to which it will apply. This requirement may be 
satisfied by posting each proposed plan or revision on the internet;
    (3) Notification to the Administrator;
    (4) Notification to each local air pollution control agency in each 
region to which the plan or revision will apply; and
    (5) In the case of an interstate region, notification to any other 
State included in the region.
    (e) The State may cancel the public hearing through a method it 
identifies if no request for a public hearing is received during the 30 
day notification period under paragraph (d) of this section and the 
original notice announcing the 30 day notification period states that if 
no request for a public hearing is received the hearing will be 
cancelled; identifies the method and time for announcing that the 
hearing

[[Page 101]]

has been cancelled; and provides a contact phone number for the public 
to call to find out if the hearing has been cancelled.
    (f) The State shall prepare and retain, for a minimum of 2 years, a 
record of each hearing for inspection by any interested party. The 
record shall contain, as a minimum, a list of witnesses together with 
the text of each presentation.
    (g) The State shall submit with the plan or revision:
    (1) Certification that each hearing required by paragraph (c) of 
this section was held in accordance with the notice required by 
paragraph (d) of this section; and
    (2) A list of witnesses and their organizational affiliations, if 
any, appearing at the hearing and a brief written summary of each 
presentation or written submission.
    (h) Upon written application by a State agency (through the 
appropriate Regional Office), the Administrator may approve State 
procedures designed to insure public participation in the matters for 
which hearings are required and public notification of the opportunity 
to participate if, in the judgment of the Administrator, the procedures, 
although different from the requirements of this subpart, in fact 
provide for adequate notice to and participation of the public. The 
Administrator may impose such conditions on his approval as he deems 
necessary. Procedures approved under this section shall be deemed to 
satisfy the requirements of this subpart regarding procedures for public 
hearings.



Sec. 60.24a  Standards of performance and compliance schedules.

    (a) Each plan shall include standards of performance and compliance 
schedules.
    (b) Standards of performance shall either be based on allowable rate 
or limit of emissions, except when it is not feasible to prescribe or 
enforce a standard of performance. The EPA shall identify such cases in 
the emission guidelines issued under Sec. 60.22a. Where standards of 
performance prescribing design, equipment, work practice, or operational 
standard, or combination thereof are established, the plan shall, to the 
degree possible, set forth the emission reductions achievable by 
implementation of such standards, and may permit compliance by the use 
of equipment determined by the State to be equivalent to that 
prescribed.
    (1) Test methods and procedures for determining compliance with the 
standards of performance shall be specified in the plan. Methods other 
than those specified in appendix A to this part or an applicable subpart 
of this part may be specified in the plan if shown to be equivalent or 
alternative methods as defined in Sec. 60.2.
    (2) Standards of performance shall apply to all designated 
facilities within the State. A plan may contain standards of performance 
adopted by local jurisdictions provided that the standards are 
enforceable by the State.
    (c) Except as provided in paragraph (e) of this section, standards 
of performance shall be no less stringent than the corresponding 
emission guideline(s) specified in subpart C of this part, and final 
compliance shall be required as expeditiously as practicable, but no 
later than the compliance times specified in an applicable subpart of 
this part.
    (d) Any compliance schedule extending more than 24 months from the 
date required for submittal of the plan must include legally enforceable 
increments of progress to achieve compliance for each designated 
facility or category of facilities. Unless otherwise specified in the 
applicable subpart, increments of progress must include, where 
practicable, each increment of progress specified in Sec. 60.21a(h) and 
must include such additional increments of progress as may be necessary 
to permit close and effective supervision of progress toward final 
compliance.
    (e) In applying a standard of performance to a particular source, 
the State may take into consideration factors, such as the remaining 
useful life of such source, provided that the State demonstrates with 
respect to each such facility (or class of such facilities):
    (1) Unreasonable cost of control resulting from plant age, location, 
or basic process design;
    (2) Physical impossibility of installing necessary control 
equipment; or

[[Page 102]]

    (3) Other factors specific to the facility (or class of facilities) 
that make application of a less stringent standard or final compliance 
time significantly more reasonable.
    (f) Nothing in this subpart shall be construed to preclude any State 
or political subdivision thereof from adopting or enforcing:
    (1) Standards of performance more stringent than emission guidelines 
specified in subpart C of this part or in applicable emission 
guidelines; or
    (2) Compliance schedules requiring final compliance at earlier times 
than those specified in subpart C of this part or in applicable emission 
guidelines.



Sec. 60.25a  Emission inventories, source surveillance, reports.

    (a) Each plan shall include an inventory of all designated 
facilities, including emission data for the designated pollutants and 
information related to emissions as specified in appendix D to this 
part. Such data shall be summarized in the plan, and emission rates of 
designated pollutants from designated facilities shall be correlated 
with applicable standards of performance. As used in this subpart, 
``correlated'' means presented in such a manner as to show the 
relationship between measured or estimated amounts of emissions and the 
amounts of such emissions allowable under applicable standards of 
performance.
    (b) Each plan shall provide for monitoring the status of compliance 
with applicable standards of performance. Each plan shall, as a minimum, 
provide for:
    (1) Legally enforceable procedures for requiring owners or operators 
of designated facilities to maintain records and periodically report to 
the State information on the nature and amount of emissions from such 
facilities, and/or such other information as may be necessary to enable 
the State to determine whether such facilities are in compliance with 
applicable portions of the plan. Submission of electronic documents 
shall comply with the requirements of 40 CFR part 3 (Electronic 
reporting).
    (2) Periodic inspection and, when applicable, testing of designated 
facilities.
    (c) Each plan shall provide that information obtained by the State 
under paragraph (b) of this section shall be correlated with applicable 
standards of performance (see Sec. 60.25a(a)) and made available to the 
general public.
    (d) The provisions referred to in paragraphs (b) and (c) of this 
section shall be specifically identified. Copies of such provisions 
shall be submitted with the plan unless:
    (1) They have been approved as portions of a preceding plan 
submitted under this subpart or as portions of an implementation plan 
submitted under section 110 of the Act; and
    (2) The State demonstrates:
    (i) That the provisions are applicable to the designated 
pollutant(s) for which the plan is submitted, and
    (ii) That the requirements of Sec. 60.26a are met.
    (e) The State shall submit reports on progress in plan enforcement 
to the Administrator on an annual (calendar year) basis, commencing with 
the first full report period after approval of a plan or after 
promulgation of a plan by the Administrator. Information required under 
this paragraph must be included in the annual report required by Sec. 
51.321 of this chapter.
    (f) Each progress report shall include:
    (1) Enforcement actions initiated against designated facilities 
during the reporting period, under any standard of performance or 
compliance schedule of the plan.
    (2) Identification of the achievement of any increment of progress 
required by the applicable plan during the reporting period.
    (3) Identification of designated facilities that have ceased 
operation during the reporting period.
    (4) Submission of emission inventory data as described in paragraph 
(a) of this section for designated facilities that were not in operation 
at the time of plan development but began operation during the reporting 
period.
    (5) Submission of additional data as necessary to update the

process data.



Sec. 60.26a  Legal authority.

    (a) Each plan or plan revision shall show that the State has legal 
authority to carry out the plan or plan revision, including authority 
to:
    (1) Adopt standards of performance and compliance schedules 
applicable to designated facilities.
    (2) Enforce applicable laws, regulations, standards, and compliance 
schedules, and seek injunctive relief.
    (3) Obtain information necessary to determine whether designated 
facilities are in compliance with applicable laws, regulations, 
standards, and compliance schedules, including authority to require 
recordkeeping and to make inspections and conduct tests of designated 
facilities.
    (4) Require owners or operators of designated facilities to install, 
maintain, and use emission monitoring devices and to make periodic 
reports to the State on the nature and amounts of emissions from such 
facilities; also authority for the State to make such data available to 
the public as reported and as correlated with applicable standards of 
performance.
    (b) The provisions of law or regulations which the State determines 
provide the authorities required by this section shall be specifically 
identified. Copies of such laws or regulations shall be submitted with 
the plan unless:
    (1) They have been approved as portions of a preceding plan 
submitted under this subpart or as portions of an implementation plan 
submitted under section 110 of the Act; and
    (2) The State demonstrates that the laws or regulations are 
applicable to the designated pollutant(s) for which the plan is 
submitted.
    (c) The plan shall show that the legal authorities specified in this 
section are available to the State at the time of submission of the 
plan. Legal authority adequate to meet the requirements of paragraphs 
(a)(3) and (4) of this section may be delegated to the State under

that the State governmental agency has the legal authority necessary to 
carry out that portion of the plan.
    (e) The State may authorize a local agency to carry out a plan, or 
portion thereof, within the local agency's jurisdiction if the plan 
demonstrates to the Administrator's satisfaction that the local agency 
has the legal authority necessary to implement the plan or portion 
thereof, and that the authorization does not relieve the State of 
responsibility under the Act for carrying out the plan or portion 
thereof.



Sec. 60.27a  Actions by the Administrator.

    (a) The Administrator may, whenever he determines necessary, shorten 
the period for submission of any plan or plan revision or portion 
thereof.
    (b) After determination that a plan or plan revision is complete per 
the requirements of Sec. 60.27a(g), the Administrator will take action 
on the plan or revision. The Administrator will, within twelve months of 
finding that a plan or plan revision is complete, approve or disapprove 
such plan or revision or each portion thereof.
    (c) The Administrator will promulgate, through notice-and-comment 
rulemaking, a federal plan, or portion thereof, at any time within two 
years after the Administrator:
    (1) Finds that a State fails to submit a required plan or plan 
revision or finds that the plan or plan revision does not satisfy the 
minimum criteria under paragraph (g) of this section; or
    (2) Disapproves the required State plan or plan revision or any 
portion thereof, as unsatisfactory because the applicable requirements 
of this subpart or an applicable subpart under this part have not been 
met.
    (d) The Administrator will promulgate a final federal plan as 
described in paragraph (c) of this section unless the State corrects the 
deficiency, and the Administrator approves the plan or plan revision, 
before the Administrator promulgates such federal plan.
    (e)(1) Except as provided in paragraph (e)(2) of this section, a 
federal plan promulgated by the Administrator under this section will 
prescribe standards of

[[Page 104]]

performance of the same stringency as the corresponding emission 
guideline(s) specified in the final emission guideline published under 
Sec. 60.22a(a) and will require compliance with such standards as 
expeditiously as practicable but no later than the times specified in 
the emission guideline.
    (2) Upon application by the owner or operator of a designated 
facility to which regulations proposed and promulgated under this 
section will apply, the Administrator may provide for the application of 
less stringent standards of performance or longer compliance schedules 
than those otherwise required by this section in accordance with the 
criteria specified in Sec. 60.24a(e).
    (f) Prior to promulgation of a federal plan under paragraph (d) of 
this section, the Administrator will provide the opportunity for at 
least one public hearing in either:
    (1) Each State that failed to submit a required complete plan or 
plan revision, or whose required plan or plan revision is disapproved by 
the Administrator; or
    (2) Washington, DC or an alternate location specified in the Federal 
Register.
    (g) Each plan or plan revision that is submitted to the 
Administrator shall be reviewed for completeness as described in 
paragraphs (g)(1) through (3) of this section.
    (1) General. Within 60 days of the Administrator's receipt of a 
state submission, but no later than 6 months after the date, if any, by 
which a State is required to submit the plan or revision, the 
Administrator shall determine whether the minimum criteria for 
completeness have been met. Any plan or plan revision that a State 
submits to the EPA, and that has not been determined by the EPA by the 
date 6 months after receipt of the submission to have failed to meet the 
minimum criteria, shall on that date be deemed by operation of law to 
meet such minimum criteria. Where the Administrator determines that a 
plan submission does not meet the minimum criteria of this paragraph, 
the State will be treated as not having made the submission and the 
requirements of Sec. 60.27a regarding promulgation of a federal plan 
shall apply.
    (2) Administrative criteria. In order to be deemed complete, a State 
plan must contain each of the following administrative criteria:
    (i) A formal letter of submittal from the Governor or her designee 
requesting EPA approval of the plan or revision thereof;
    (ii) Evidence that the State has adopted the plan in the state code 
or body of regulations; or issued the permit, order, consent agreement 
(hereafter ``document'') in final form. That evidence must include the 
date of adoption or final issuance as well as the effective date of the 
plan, if different from the adoption/issuance date;
    (iii) Evidence that the State has the necessary legal authority 
under state law to adopt and implement the plan;
    (iv) A copy of the actual regulation, or document submitted for 
approval and incorporation by reference into the plan, including 
indication of the changes made (such as redline/strikethrough) to the 
existing approved plan, where applicable. The submittal must be a copy 
of the official state regulation or document signed, stamped and dated 
by the appropriate state official indicating that it is fully 
enforceable by the State. The effective date of the regulation or 
document must, whenever possible, be indicated in the document itself. 
The State's electronic copy must be an exact duplicate of the hard copy. 
If the regulation/document provided by the State for approval and 
incorporation by reference into the plan is a copy of an existing 
publication, the State submission should, whenever possible, include a 
copy of the publication cover page and table of contents;
    (v) Evidence that the State followed all of the procedural 
requirements of the state's laws and constitution in conducting and 
completing the adoption and issuance of the plan;
    (vi) Evidence that public notice was given of the proposed change 
with procedures consistent with the requirements of Sec. 60.23a, 
including the date of publication of such notice;
    (vii) Certification that public hearing(s) were held in accordance 
with the information provided in the public notice and the State's laws 
and constitution, if applicable and consistent with

the public hearing requirements in Sec. 60.23a;
    (viii) Compilation of public comments and the State's response 
thereto; and
    (ix) Such other criteria for completeness as may be specified by the 
Administrator under the applicable emission guidelines.
    (3) Technical criteria. In order to be deemed complete, a State plan 
must contain each of the following technical criteria:
    (i) Description of the plan approach and geographic scope;
    (ii) Identification of each designated facility, identification of 
standards of performance for the designated facilities, and monitoring, 
recordkeeping and reporting requirements that will determine compliance 
by each designated facility;
    (iii) Identification of compliance schedules and/or increments of 
progress;
    (iv) Demonstration that the State plan submittal is projected to 
achieve emissions performance under the applicable emission guidelines;
    (v) Documentation of state recordkeeping and reporting requirements 
to determine the performance of the plan as a whole; and
    (vi) Demonstration that each emission standard is quantifiable, non-
duplicative, permanent, verifiable, and enforceable.



Sec. 60.28a  Plan revisions by the State.

    (a) Any revision to a state plan shall be adopted by such State 
after reasonable notice and public hearing. For plan revisions required 
in response to a revised emission guideline, such plan revisions shall 
be submitted to the Administrator within three years, or shorter if 
required by the Administrator, after notice of the availability of a 
final revised emission guideline is published under Sec. 60.22a. All 
plan revisions must be submitted in accordance with the procedures and 
requirements applicable to development and submission of the original 
plan.
    (b) A revision of a plan, or any portion thereof, shall not be 
considered part of an applicable plan until approved by the 
Administrator in accordance with this subpart.

Subpart Cc_Emission Guidelines and Compliance Times for Municipal Solid 
                             Waste Landfills

    Source: 61 FR 9919, Mar. 12, 1996, unless otherwise noted.



Sec. 60.30c  Scope.

    This subpart contains emission guidelines and compliance times for 
the control of certain designated pollutants from certain designated 
municipal solid waste landfills in accordance with section 111(d) of the 
Act and subpart B.



Sec. 60.31c  Definitions.

    Terms used but not defined in this subpart have the meaning given 
them in the Act and in subparts A, B, and WWW of this part.
    Municipal solid waste landfill or MSW landfill means an entire 
disposal facility in a contiguous geographical space where household 
waste is placed in or on land. An MSW landfill may also receive other 
types of RCRA Subtitle D wastes such as commercial solid waste, 
nonhazardous sludge, conditionally exempt small quantity generator 
waste, and industrial solid waste. Portions of an MSW landfill may be 
separated by access roads. An MSW landfill may be publicly or privately 
owned. An MSW landfill may be a new MSW landfill, an existing MSW 
landfill or a lateral expansion.



Sec. 60.32c  Designated facilities.

    (a) The designated facility to which the guidelines apply is each 
existing MSW landfill for which construction, reconstruction or 
modification was commenced before May 30, 1991.
    (b) Physical or operational changes made to an existing MSW landfill 
solely to comply with an emission guideline are not considered a 
modification or reconstruction and would not subject an existing MSW 
landfill to the requirements of subpart WWW [see Sec. 60.750 of subpart 
WWW].
    (c) For purposes of obtaining an operating permit under title V of 
the Act, the owner or operator of a MSW landfill subject to this subpart 
with a design capacity less than 2.5 million megagrams or 2.5 million 
cubic meters is not subject to the requirement to obtain an operating 
permit for the landfill under part 70 or 71 of this chapter, unless the 
landfill is otherwise subject to either part 70 or 71. For purposes of 
submitting a timely application for an operating permit under part 70 or 
71, the owner or operator of a MSW landfill subject to this subpart with 
a design capacity greater than or equal to 2.5 million megagrams and 2.5 
million cubic meters on the effective date of EPA approval of the 
State's program under section 111(d) of the Act, and not otherwise 
subject to either part 70 or 71, becomes subject to the requirements of 
Sec. Sec. 70.5(a)(1)(i) or 71.5(a)(1)(i) of this chapter 90 days after 
the effective date of such 111(d) program approval, even if the design 
capacity report is submitted earlier.
    (d) When a MSW landfill subject to this subpart is closed, the owner 
or operator is no longer subject to the requirement to maintain an 
operating permit under part 70 or 71 of this chapter for the landfill if 
the landfill is not otherwise subject to the requirements of either part 
70 or 71 and if either of the following conditions are met.

[[Page 116]]

    (1) The landfill was never subject to the requirement for a control 
system under Sec. 60.33c(c) of this subpart; or
    (2) The owner or operator meets the conditions for control system 
removal specified in Sec. 60.752(b)(2)(v) of subpart WWW.

[61 FR 9919, Mar. 12, 1996, as amended at 63 FR 32750, June 16, 1998]



Sec. 60.33c  Emission guidelines for municipal solid waste landfill emissions.

    (a) For approval, a State plan shall include control of MSW landfill 
emissions at each MSW landfill meeting the following three conditions:
    (1) The landfill has accepted waste at any time since November 8, 
1987, or has additional design capacity available for future waste 
deposition;
    (2) The landfill has a design capacity greater than or equal to 2.5 
million megagrams and 2.5 million cubic meters. The landfill may 
calculate design capacity in either megagrams or cubic meters for 
comparison with the exemption values. Any density conversions shall be 
documented and submitted with the design capacity report; and
    (3) The landfill has a nonmethane organic compound emission rate of 
50 megagrams per year or more.
    (b) For approval, a State plan shall include the installation of a 
collection and control system meeting the conditions provided in Sec. 
60.752(b)(2)(ii) of this part at each MSW landfill meeting the 
conditions in paragraph (a) of this section. The State plan shall 
include a process for State review and approval of the site-specific 
design plans for the gas collection and control system(s).
    (c) For approval, a State plan shall include provisions for the 
control of collected MSW landfill emissions through the use of control 
devices meeting the requirements of paragraph (c)(1), (2), or (3) of 
this section, except as provided in Sec. 60.24.

than observed during the previous emissions test(s), and the HMIWI may 
not have been modified such that emissions would be expected to exceed 
(notwithstanding normal test-to-test variability) the results from 
previous emissions test(s).
    (3) The previous emissions test(s) must have been conducted in 1996 
or later.

Sec. 60.39e  Compliance times.

    (a) Each State in which a designated facility is operating shall 
submit to the Administrator a plan to implement and enforce the 
emissions guidelines as specified in paragraphs (a)(1) and (a)(2) of 
this section:
    (1) Not later than September 15, 1998, for the emissions guidelines 
as promulgated on September 15, 1997.
    (2) Not later than October 6, 2010, for the emissions guidelines as 
amended on October 6, 2009.
    (b) Except as provided in paragraphs (c) and (d) of this section, 
State plans shall provide that designated facilities comply with all 
requirements of the State plan on or before the date 1 year after EPA 
approval of the State plan, regardless of whether a designated facility 
is identified in the State plan inventory required by Sec. 60.25(a) of 
subpart B of this part.
    (c) State plans that specify measurable and enforceable incremental 
steps of progress towards compliance for designated facilities planning 
to install the necessary air pollution control equipment may allow 
compliance on or before the date 3 years after EPA approval of the State 
plan (but not later than September 16, 2002), for the emissions 
guidelines as promulgated on September 15, 1997, and on or before the 
date 3 years after approval of an amended State plan (but not later than 
October 6, 2014), for the emissions guidelines as amended on October 6, 
2009). Suggested measurable and enforceable activities to be included in 
State plans are:
    (1) Date for submitting a petition for site-specific operating 
parameters under Sec. 60.56c(j) of subpart Ec of this part.
    (2) Date for obtaining services of an architectural and engineering 
firm regarding the air pollution control device(s);
    (3) Date for obtaining design drawings of the air pollution control 
device(s);
    (4) Date for ordering the air pollution control device(s);
    (5) Date for obtaining the major components of the air pollution 
control device(s);
    (6) Date for initiation of site preparation for installation of the 
air pollution control device(s);
    (7) Date for initiation of installation of the air pollution control 
device(s);
    (8) Date for initial startup of the air pollution control device(s); 
and
    (9) Date for initial compliance test(s) of the air pollution control 
device(s).
    (d) State plans that include provisions allowing designated 
facilities to petition the State for extensions beyond the compliance 
times required in paragraph (b) of this section shall:

[[Page 124]]

    (1) Require that the designated facility requesting an extension 
submit the following information in time to allow the State adequate 
time to grant or deny the extension within 1 year after EPA approval of 
the State plan:
    (i) Documentation of the analyses undertaken to support the need for 
an extension, including an explanation of why up to 3 years after EPA 
approval of the State plan is sufficient time to comply with the State 
plan while 1 year after EPA approval of the State plan is not 
sufficient. The documentation shall also include an evaluation of the 
option to transport the waste offsite to a commercial medical waste 
treatment and disposal facility on a temporary or permanent basis; and
    (ii) Documentation of measurable and enforceable incremental steps 
of progress to be taken towards compliance with the emission guidelines.
    (2) Include procedures for granting or denying the extension; and
    (3) If an extension is granted, require expeditious compliance with 
the emissions guidelines on or before the date 3 years after EPA 
approval of the state plan (but not later than September 16, 2002), for 
the emissions guidelines as promulgated on September 15, 1997, and on or 
before the date 3 years after EPA approval of an amended state plan (but 
not later than October 6, 2014), for the emissions guidelines as amended 
on October 6, 2009.
    (e) For approval, a State plan shall require compliance with Sec. 
60.34e--Operator training and qualification guidelines and Sec. 
60.36e--Inspection guidelines by the date 1 year after EPA approval of a 
State plan.
    (f) The Administrator shall develop, implement, and enforce a plan 
for existing HMIWI located in any State that has not submitted an 
approvable plan within 2 years after September 15, 1997, for the 
emissions guidelines as promulgated on September 15, 1997, and within 2 
years after October 6, 2009 for the emissions guidelines as amended on 
October 6, 2009. Such plans shall ensure that each designated facility 
is in compliance with the provisions of this subpart no later than 5 
years after September 15, 1997, for the emissions guidelines as 
promulgated on September 15, 1997, and no later than 5 years after 
October 6, 2009 for the emissions guidelines as amended on October 6, 
2009.

or reconstruction and would not subject an existing MSW landfill to the 
requirements of a standard of performance for new MSW landfills.
    (c) For purposes of obtaining an operating permit under title V of 
the Clean Air Act, the owner or operator of an MSW landfill subject to 
this subpart with a design capacity less than 2.5 million megagrams or 
2.5 million cubic meters is not subject to the requirement to obtain an 
operating permit for the landfill under part 70 or 71 of this chapter, 
unless the landfill is otherwise subject to either part 70 or 71. For 
purposes of submitting a timely application for an operating permit 
under part 70 or 71, the owner or operator of an MSW landfill subject to 
this subpart with a design capacity greater than or equal to 2.5 million 
megagrams and 2.5 million cubic meters on the effective date of EPA 
approval of the state's program under section 111(d) of the Clean Air 
Act, and not otherwise subject to either part 70 or 71, becomes subject 
to the requirements of Sec. 70.5(a)(1)(i) or Sec. 71.5(a)(1)(i) of 
this chapter 90 days after the effective date of such section 111(d) 
program approval, even if the design capacity report is submitted 
earlier.
    (d) When an MSW landfill subject to this subpart is closed as 
defined in this subpart, the owner or operator is no longer subject to 
the requirement to maintain an operating permit under part 70 or 71 of 
this chapter for the landfill if the landfill is not otherwise subject 
to the requirements of either part 70 or 71 and if either of the 
following conditions are met:
    (1) The landfill was never subject to the requirement to install and 
operate a gas collection and control system under Sec. 60.33f; or
    (2) The landfill meets the conditions for control system removal 
specified in Sec. 60.33f(f).
    (e) When an MSW landfill subject to this subpart is in the closed 
landfill subcategory, the owner or operator is not subject to the 
following reports of this subpart, provided the owner or operator 
submitted these reports under the provisions of subpart WWW of this 
part; 40 CFR part 62, subpart GGG; or a state plan implementing subpart 
Cc of this part on or before July 17, 2014:
    (1) Initial design capacity report specified in Sec. 60.38f(a).
    (2) Initial or subsequent NMOC emission rate report specified in 
Sec. 60.38f(c), provided that the most recent NMOC emission rate report 
indicated the NMOC emissions were below 50 Mg/yr.
    (3) Collection and control system design plan specified in Sec. 
60.38f(d).
    (4) Closure report specified in Sec. 60.38f(f).

    (6) Initial annual report specified in Sec. 60.38f(h).
    (7) Initial performance test report in Sec. 60.38f(i).



Sec. 60.32f  Compliance times.

    Planning, awarding of contracts, installing, and starting up MSW 
landfill air emission collection and control equipment that is capable 
of meeting the Emission Guidelines under Sec. 60.33f must be completed 
within 30 months after the date an NMOC emission rate report shows NMOC 
emissions equal or exceed 34 megagrams per year (50 megagrams per year 
for the closed landfill subcategory); or within 30 months after the date 
of the most recent NMOC emission rate report that shows NMOC emissions 
equal or exceed 34 megagrams per year (50 megagrams per year for the 
closed landfill subcategory), if Tier 4 surface emissions monitoring 
shows a surface emission concentration of 500 parts per million methane 
or greater.



Sec. 60.33f  Emission Guidelines for municipal solid waste landfill emissions.

    (a) Landfills. For approval, a state plan must require each owner or 
operator of an MSW landfill having a design capacity greater than or 
equal to 2.5 million megagrams by mass and 2.5 million cubic meters by 
volume to collect and control MSW landfill emissions at each MSW 
landfill that meets the following conditions:
    (1) The landfill has accepted waste at any time since November 8, 
1987, or has additional design capacity available for future waste 
deposition.
    (2) The landfill commenced construction, reconstruction, or 
modification on or before July 17, 2014.

[[Page 130]]

    (3) The landfill has an NMOC emission rate greater than or equal to 
34 megagrams per year or Tier 4 surface emissions monitoring shows a 
surface emission concentration of 500 parts per million methane or 
greater.
    (4) The landfill in the closed landfill subcategory and has an NMOC 
emission rate greater than or equal to 50 megagrams per year or Tier 4 
surface emissions monitoring shows a surface emission concentration of 
500 parts per million methane or greater.
    (b) Collection system. For approval, a state plan must include 
provisions for the installation of a gas collection and control system 
meeting the requirements in paragraphs (b)(1) through (3) and (c) of 
this section at each MSW landfill meeting the conditions in paragraph 
(a) of this section.
    (1) Collection system. Install and start up a collection and control 
system that captures the gas generated within the landfill within 30 
months after:
    (i) The first annual report in which the NMOC emission rate equals 
or exceeds 34 megagrams per year, unless Tier 2 or Tier 3 sampling 
demonstrates that the NMOC emission rate is less than 34 megagrams per 
year, as specified in Sec. 60.38f(d)(4); or
    (ii) The first annual NMOC emission rate report for a landfill in 
the closed landfill subcategory in which the NMOC emission rate equals 
or exceeds 50 megagrams per year, unless Tier 2 or Tier 3 sampling 
demonstrates that the NMOC emission rate is less than 50 megagrams per 
year, as specified in Sec. 60.38f(d)(4); or
    (iii) The most recent NMOC emission rate report in which the NMOC 
emission rate equals or exceeds 34 megagrams per year based on Tier 2, 
if the Tier 4 surface emissions monitoring shows a surface methane 
emission concentration of 500 parts per million methane or greater as 
specified in Sec. 60.38f(d)(4)(iii).
    (2) Active. An active collection system must:
    (i) Be designed to handle the maximum expected gas flow rate from 
the entire area of the landfill that warrants control over the intended 
use period of the gas control system equipment.
    (ii) Collect gas from each area, cell, or group of cells in the 
landfill in which the initial solid waste has been placed for a period 
of 5 years or more if active; or 2 years or more if closed or at final 
grade.
    (iii) Collect gas at a sufficient extraction rate.
    (iv) Be designed to minimize off-site migration of subsurface gas.
    (3) Passive. A passive collection system must:
    (i) Comply with the provisions specified in paragraphs (b)(2)(i), 
(ii), and (iv) of this section.
    (ii) Be installed with liners on the bottom and all sides in all 
areas in which gas is to be collected. The liners must be installed as 
required under Sec. 258.40 of this chapter.
    (c) Control system. For approval, a state plan must include 
provisions for the control of the gas collected from within the landfill 
through the use of control devices meeting the following requirements, 
except as provided in Sec. 60.24.
    (1) A non-enclosed flare designed and operated in accordance with 
the parameters established in Sec. 60.18 except as noted in Sec. 
60.37f(d); or
    (2) A control system designed and operated to reduce NMOC by 98 
weight percent; or when an enclosed combustion device is used for 
control, to either reduce NMOC by 98 weight percent or reduce the outlet 
NMOC concentration to less than 20 parts per million by volume, dry 
basis as hexane at 3 percent oxygen or less. The reduction efficiency or 
concentration in parts per million by volume must be established by an 
initial performance test to be completed no later than 180 days after 
the initial startup of the approved control system using the test 
methods specified in Sec. 60.35f(d). The performance test is not 
required for boilers and process heaters with design heat input 
capacities equal to or greater than 44 megawatts that burn landfill gas 
for compliance with this subpart.
    (i) If a boiler or process heater is used as the control device, the 
landfill gas stream must be introduced into the flame zone.

[[Page 131]]

    (ii) The control device must be operated within the parameter ranges 
established during the initial or most recent performance test. The 
operating parameters to be monitored are specified in Sec. 60.37f.
    (iii) For the closed landfill subcategory, the initial or most 
recent performance test conducted to comply with subpart WWW of this 
part; 40 CFR part 62, subpart GGG; or a state plan implementing subpart 
Cc of this part on or before July 17, 2014 is sufficient for compliance 
with this subpart.
    (3) Route the collected gas to a treatment system that processes the 
collected gas for subsequent sale or beneficial use such as fuel for 
combustion, production of vehicle fuel, production of high-Btu gas for 
pipeline injection, or use as a raw material in a chemical manufacturing 
process. Venting of treated landfill gas to the ambient air is not 
allowed. If the treated landfill gas cannot be routed for subsequent 
sale or beneficial use, then the treated landfill gas must be controlled 
according to either paragraph (c)(1) or (2) of this section.
    (4) All emissions from any atmospheric vent from the gas treatment 
system are subject to the requirements of paragraph (b) or (c) of this 
section. For purposes of this subpart, atmospheric vents located on the 
condensate storage tank are not part of the treatment system and are 
exempt from the requirements of paragraph (b) or (c) of this section.
    (d) Design capacity. For approval, a state plan must require each 
owner or operator of an MSW landfill having a design capacity less than 
2.5 million megagrams by mass or 2.5 million cubic meters by volume to 
submit an initial design capacity report to the Administrator as 
provided in Sec. 60.38f(a). The landfill may calculate design capacity 
in either megagrams or cubic meters for comparison with the exemption 
values. Any density conversions must be documented and submitted with 
the report. Submittal of the initial design capacity report fulfills the 
requirements of this subpart except as provided in paragraphs (d)(1) and 
(2) of this section.
    (1) The owner or operator must submit an amended design capacity 
report as provided in Sec. 60.38f(b).

    Note to paragraph (d)(1): Note that if the design capacity increase 
is the result of a modification, as defined in this subpart, that was 
commenced after July 17, 2014, then the landfill becomes subject to 
subpart XXX of this part instead of this subpart. If the design capacity 
increase is the result of a change in operating practices, density, or 
some other change that is not a modification as defined in this subpart, 
then the landfill remains subject to this subpart.

    (2) When an increase in the maximum design capacity of a landfill 
with an initial design capacity less than 2.5 million megagrams or 2.5 
million cubic meters results in a revised maximum design capacity equal 
to or greater than 2.5 million megagrams and 2.5 million cubic meters, 
the owner or operator must comply with paragraph (e) of this section.
    (e) Emissions. For approval, a state plan must require each owner or 
operator of an MSW landfill having a design capacity equal to or greater 
than 2.5 million megagrams and 2.5 million cubic meters to either 
install a collection and control system as provided in paragraphs (b) 
and (c) of this section or calculate an initial NMOC emission rate for 
the landfill using the procedures specified in Sec. 60.35f(a). The NMOC 
emission rate must be recalculated annually, except as provided in Sec. 
60.38f(c)(3).
    (1) If the calculated NMOC emission rate is less than 34 megagrams 
per year, the owner or operator must:
    (i) Submit an annual NMOC emission rate report according to Sec. 
60.38f(c), except as provided in Sec. 60.38f(c)(3); and
    (ii) Recalculate the NMOC emission rate annually using the 
procedures specified in Sec. 60.35f(a) until such time as the 
calculated NMOC emission rate is equal to or greater than 34 megagrams 
per year, or the landfill is closed.
    (A) If the calculated NMOC emission rate, upon initial calculation 
or annual recalculation required in paragraph (e)(1)(ii) of this 
section, is equal to or greater than 34 megagrams per year, the owner or 
operator must either: Comply with paragraphs (b) and (c) of this 
section; calculate NMOC emissions using the next higher tier in Sec. 
60.35f; or

[[Page 132]]

conduct a surface emission monitoring demonstration using the procedures 
specified in Sec. 60.35f(a)(6).
    (B) If the landfill is permanently closed, a closure report must be 
submitted to the Administrator as provided in Sec. 60.38f(f), except 
for exemption allowed under Sec. 60.31f(e)(4).
    (C) For the closed landfill subcategory, if the most recently 
calculated NMOC emission rate is equal to or greater than 50 megagrams 
per year, the owner or operator must either: Submit a gas collection and 
control system design plan as specified in Sec. 60.38f(d), except for 
exemptions allowed under Sec. 60.31f(e)(3), and install a collection 
and control system as provided in paragraphs (b) and (c) of this 
section; calculate NMOC emissions using the next higher tier in Sec. 
60.35f; or conduct a surface emission monitoring demonstration using the 
procedures specified in Sec. 60.35f(a)(6).
    (2) If the calculated NMOC emission rate is equal to or greater than 
34 megagrams per year using Tier 1, 2, or 3 procedures, the owner or 
operator must either: submit a collection and control system design plan 
prepared by a professional engineer to the Administrator within 1 year 
as specified in Sec. 60.38f(d), except for exemptions allowed under 
Sec. 60.31f(e)(3); calculate NMOC emissions using a higher tier in 
Sec. 60.35f; or conduct a surface emission monitoring demonstration 
using the procedures specified in Sec. 60.35f(a)(6).
    (3) For the closed landfill subcategory, if the calculated NMOC 
emission rate is equal to or greater than 50 megagrams per year using 
Tier 1, 2, or 3 procedures, the owner or operator must either: Submit a

60.38f(d), except for exemptions allowed under Sec. 60.31f(e)(3); 
calculate NMOC emissions using a higher tier in Sec. 60.35f; or conduct 
a surface emission monitoring demonstration using the procedures 
specified in Sec. 60.35f(a)(6).
    (f) Removal criteria. The collection and control system may be 
capped, removed, or decommissioned if the following criteria are met:
    (1) The landfill is a closed landfill (as defined in Sec. 60.41f). 
A closure report must be submitted to the Administrator as provided in 
Sec. 60.38f(f).
    (2) The collection and control system has been in operation a 
minimum of 15 years or the landfill owner or operator demonstrates that 
the GCCS will be unable to operate for 15 years due to declining gas 
flow.
    (3) Following the procedures specified in Sec. 60.35f(b), the 
calculated NMOC emission rate at the landfill is less than 34 megagrams 
per year on three successive test dates. The test dates must be no less 
than 90 days apart, and no more than 180 days apart.
    (4) For the closed landfill subcategory (as defined in Sec. 60.41), 
following the procedures specified in Sec. 60.35f(b), the calculated 
NMOC emission rate at the landfill is less than 50 megagrams per year on 
three successive test dates. The test dates must be no less than 90 days 
apart, and no more than 180 days apart.



Sec. 60.34f  Operational standards for collection and control systems.

    For approval, a state plan must include provisions for the 
operational standards in this section (as well as the provisions in 
Sec. Sec. 60.36f and 60.37f), or the operational standards in Sec. 
63.1958 of this chapter (as well as the provisions in Sec. Sec. 63.1960 
of this chapter and 63.1961 of this chapter), or both as alternative 
means of compliance, for an MSW landfill with a gas collection and 
control system used to comply with the provisions of Sec. 60.33f(b) and 
(c). Once the owner or operator begins to comply with the provisions of 
Sec. 63.1958 of this chapter, the owner or operator must continue to 
operate the collection and control device according to those provisions 
and cannot return to the provisions of this section. Each owner or 
operator of an MSW landfill with a gas collection and control system 
used to comply with the provisions of Sec. 60.33f(b) and (c) must:
    (a) Operate the collection system such that gas is collected from 
each area, cell, or group of cells in the MSW landfill in which solid 
waste has been in place for:
    (1) Five (5) years or more if active; or
    (2) Two (2) years or more if closed or at final grade.

[[Page 133]]

    (b) Operate the collection system with negative pressure at each 
wellhead except under the following conditions:
    (1) A fire or increased well temperature. The owner or operator must 
record instances when positive pressure occurs in efforts to avoid a 
fire. These records must be submitted with the annual reports as 
provided in Sec. 60.38f(h)(1).
    (2) Use of a geomembrane or synthetic cover. The owner or operator 
must develop acceptable pressure limits in the design plan.
    (3) A decommissioned well. A well may experience a static positive 
pressure after shut down to accommodate for declining flows. All design 
changes must be approved by the Administrator as specified in Sec. 
60.38f(d).
    (c) Operate each interior wellhead in the collection system with a 
landfill gas temperature less than 55 degrees Celsius (131 degrees 
Fahrenheit). The owner or operator may establish a higher operating 
temperature value at a particular well. A higher operating value 
demonstration must be submitted to the Administrator for approval and 
must include supporting data demonstrating that the elevated parameter 
neither causes fires nor significantly inhibits anaerobic decomposition 
by killing methanogens. The demonstration must satisfy both criteria in 
order to be approved (i.e., neither causing fires nor killing 
methanogens is acceptable).
    (d) Operate the collection system so that the methane concentration 
is less than 500 parts per million above background at the surface of 
the landfill. To determine if this level is exceeded, the owner or 
operator must conduct surface testing using an organic vapor analyzer, 
flame ionization detector, or other portable monitor meeting the 
specifications provided in Sec. 60.36(d). The owner or operator must 
conduct surface testing around the perimeter of the collection area and 
along a pattern that traverses the landfill at no more than 30-meter 
intervals and where visual observations indicate elevated concentrations 
of landfill gas, such as distressed vegetation and cracks or seeps in 
the cover and all cover penetrations. Thus, the owner or operator must 
monitor any openings that are within an area of the landfill where waste 
has been placed and a gas collection system is required. The owner or 
operator may establish an alternative traversing pattern that ensures 
equivalent coverage. A surface monitoring design plan must be developed 
that includes a topographical map with the monitoring route and the 
rationale for any site-specific deviations from the 30-meter intervals. 
Areas with steep slopes or other dangerous areas may be excluded from 
the surface testing.
    (e) Operate the system such that all collected gases are vented to a 
control system designed and operated in compliance with Sec. 60.33f(c). 
In the event the collection or control system is not operating, the gas 
mover system must be shut down and all valves in the collection and 
control system contributing to venting of the gas to the atmosphere must 
be closed within 1 hour of the collection or control system not 
operating.
    (f) Operate the control system at all times when the collected gas 
is routed to the system.
    (g) If monitoring demonstrates that the operational requirements in 
paragraph (b), (c), or (d) of this section are not met, corrective 
action must be taken as specified in Sec. 60.36f(a)(3) and (5) or (c). 
If corrective actions are taken as specified in Sec. 60.36f, the 
monitored exceedance is not a violation of the operational requirements 
in this section.

Sec. 60.35f  Test methods and procedures.

    For approval, a state plan must include provisions in this section 
to calculate the landfill NMOC emission rate or to conduct a surface 
emission monitoring demonstration.
    (a)(1) NMOC Emission Rate. The landfill owner or operator must 
calculate the NMOC emission rate using either Equation 1 provided in 
paragraph (a)(1)(i) of this section or Equation 2 provided in paragraph 
(a)(1)(ii) of this section. Both Equation 1 and Equation 2 may be used 
if the actual year-to-year solid waste acceptance rate is known, as 
specified in paragraph (a)(1)(i) of this section, for part of the life 
of the landfill and the actual year-

[[Page 134]]

to-year solid waste acceptance rate is unknown, as specified in 
paragraph (a)(1)(ii) of this section, for part of the life of the 
landfill. The values to be used in both Equation 1 and Equation 2 are 
0.05 per year for k, 170 cubic meters per megagram for Lo, and 4,000 
parts per million by volume as hexane for the CNMOC. For 
landfills located in geographical areas with a 30-year annual average 
precipitation of less than 25 inches, as measured at the nearest 
representative official meteorologic site, the k value to be used is 
0.02 per year.
    (i)(A) Equation 1 must be used if the actual year-to-year solid 
waste acceptance rate is known.
[GRAPHIC] [TIFF OMITTED] TR29AU16.000

Where:

MNMOC = Total NMOC emission rate from the landfill, megagrams 
          per year.
k = Methane generation rate constant, year-1.
Lo = Methane generation potential, cubic meters per megagram 
          solid waste.
Mi = Mass of solid waste in the i\th\ section, megagrams.
ti = Age of the i\th\ section, years.
CNMOC = Concentration of NMOC, parts per million by volume as 
          hexane.
3.6 x 10-9 = Conversion factor.

    (B) The mass of nondegradable solid waste may be subtracted from the 
total mass of solid waste in a particular section of the landfill when 
calculating the value for Mi if documentation of the nature 
and amount of such wastes is maintained.
    (ii)(A) Equation 2 must be used if the actual year-to-year solid 
waste acceptance rate is unknown.
[GRAPHIC] [TIFF OMITTED] TR29AU16.001

Where:

MNMOC = Mass emission rate of NMOC, megagrams per year.
Lo = Methane generation potential, cubic meters per megagram 
          solid waste.
R = Average annual acceptance rate, megagrams per year.
k = Methane generation rate constant, year -1.
t = Age of landfill, years.
CNMOC = Concentration of NMOC, parts per million by volume as 
          hexane.
c = Time since closure, years; for an active landfill c = 0 and 
          e-kc = 1.
3.6 x 10-9 = Conversion factor.

    (B) The mass of nondegradable solid waste may be subtracted from the 
total mass of solid waste in a particular section of the landfill when 
calculating the value of R, if documentation of the nature and amount of 
such wastes is maintained.
    (2) Tier 1. The owner or operator must compare the calculated NMOC 
mass emission rate to the standard of 34 megagrams per year.
    (i) If the NMOC emission rate calculated in paragraph (a)(1) of this 
section is less than 34 megagrams per year, then the owner or operator 
must submit an NMOC emission rate report according to Sec. 60.38f(c), 
and must recalculate the NMOC mass emission rate annually as required 
under Sec. 60.33f(e).
    (ii) If the NMOC emission rate calculated in paragraph (a)(1) of 
this section is equal to or greater than 34 megagrams per year, then the 
landfill owner or operator must either:
    (A) Submit a gas collection and control system design plan within 1 
year as specified in Sec. 60.38f(d) and install and operate a gas 
collection and control system within 30 months according to Sec. 
60.33f(b) and (c);
    (B) Determine a site-specific NMOC concentration and recalculate the 
NMOC emission rate using the Tier 2 procedures provided in paragraph 
(a)(3) of this section; or
    (C) Determine a site-specific methane generation rate constant and 
recalculate the NMOC emission rate using the Tier 3 procedures provided 
in paragraph (a)(4) of this section.

[[Page 135]]

    (3) Tier 2. The landfill owner or operator must determine the site-
specific NMOC concentration using the following sampling procedure. The 
landfill owner or operator must install at least two sample probes per 
hectare, evenly distributed over the landfill surface that has retained 
waste for at least 2 years. If the landfill is larger than 25 hectares 
in area, only 50 samples are required. The probes should be evenly 
distributed across the sample area. The sample probes should be located 
to avoid known areas of nondegradable solid waste. The owner or operator 
must collect and analyze one sample of landfill gas from each probe to 
determine the NMOC concentration using Method 25 or 25C of appendix A of 
this part. Taking composite samples from different probes into a single 
cylinder is allowed; however, equal sample volumes must be taken from 
each probe. For each composite, the sampling rate, collection times, 
beginning and ending cylinder vacuums, or alternative volume 
measurements must be recorded to verify that composite volumes are 
equal. Composite sample volumes should not be less than one liter unless 
evidence can be provided to substantiate the accuracy of smaller 
volumes. Terminate compositing before the cylinder approaches ambient 
pressure where measurement accuracy diminishes. If more than the 
required number of samples is taken, all samples must be used in the 
analysis. The landfill owner or operator must divide the NMOC 
concentration from Method 25 or 25C by six to convert from 
CNMOC as carbon to CNMOC as hexane. If the 
landfill has an active or passive gas removal system in place, Method 25 
or 25C samples may be collected from these systems instead of surface 
probes provided the removal system can be shown to provide sampling as 
representative as the two sampling probe per hectare requirement. For 
active collection systems, samples may be collected from the common 
header pipe. The sample location on the common header pipe must be 
before any gas moving, condensate removal, or treatment system 
equipment. For active collection systems, a minimum of three samples 
must be collected from the header pipe.
    (i) Within 60 days after the date of determining the NMOC 
concentration and corresponding NMOC emission rate, the owner or 
operator must submit the results according to Sec. 60.38f(j)(2).
    (ii) The landfill owner or operator must recalculate the NMOC mass 
emission rate using Equation 1 or Equation 2 provided in paragraph 
(a)(1)(i) or (ii) of this section using the average site-specific NMOC 
concentration from the collected samples instead of the default value 
provided in paragraph (a)(1) of this section.
    (iii) If the resulting NMOC mass emission rate is less than 34 
megagrams per year, then the owner or operator must submit a periodic 
estimate of NMOC emissions in an NMOC emission rate report according to 
Sec. 60.38f(c), and must recalculate the NMOC mass emission rate 
annually as required under Sec. 60.33f(e). The site-specific NMOC 
concentration must be retested every 5 years using the methods specified 
in this section.
    (iv) If the NMOC mass emission rate as calculated using the Tier 2 
site-specific NMOC concentration is equal to or greater than 34 
megagrams per year, the owner or operator must either:
    (A) Submit a gas collection and control system design plan within 1 
year as specified in Sec. 60.38f(d) and install and operate a gas 
collection and control system within 30 months according to Sec. 
60.33f(b) and (c);
    (B) Determine a site-specific methane generation rate constant and 
recalculate the NMOC emission rate using the site-specific methane 
generation rate using the Tier 3 procedures specified in paragraph 
(a)(4) of this section; or
    (C) Conduct a surface emission monitoring demonstration using the 
Tier 4 procedures specified in paragraph (a)(6) of this section.
    (4) Tier 3. The site-specific methane generation rate constant must 
be determined using the procedures provided in Method 2E of appendix A 
of this part. The landfill owner or operator must estimate the NMOC mass 
emission rate using Equation 1 or Equation 2 in paragraph (a)(1)(i) or 
(ii) of this section and using a site-specific methane generation rate 
constant, and the

[[Page 136]]

site-specific NMOC concentration as determined in paragraph (a)(3) of 
this section instead of the default values provided in paragraph (a)(1) 
of this section. The landfill owner or operator must compare the 
resulting NMOC mass emission rate to the standard of 34 megagrams per 
year.
    (i) If the NMOC mass emission rate as calculated using the Tier 2 
site-specific NMOC concentration and Tier 3 site-specific methane 
generation rate is equal to or greater than 34 megagrams per year, the 
owner or operator must either:
    (A) Submit a gas collection and control system design plan within 1 
year as specified in Sec. 60.38f(d) and install and operate a gas 
collection and control system within 30 months according to Sec. 
60.33f(b) and (c); or
    (B) Conduct a surface emission monitoring demonstration using the 
Tier 4 procedures specified in paragraph (a)(6) of this section.
    (ii) If the NMOC mass emission rate is less than 34 megagrams per 
year, then the owner or operator must recalculate the NMOC mass emission 
rate annually using Equation 1 or Equation 2 in paragraph (a)(1) of this 
section and using the site-specific Tier 2 NMOC concentration and Tier 3 
methane generation rate constant and submit a periodic NMOC emission 
rate report as provided in Sec. 60.38f(c). The calculation of the 
methane generation rate constant is performed only once, and the value 
obtained from this test must be used in all subsequent annual NMOC 
emission rate calculations.
    (5) Other methods. The owner or operator may use other methods to 
determine the NMOC concentration or a site-specific methane generation 
rate constant as an alternative to the methods required in paragraphs 
(a)(3) and (4) of this section if the method has been approved by the 
Administrator.
    (6) Tier 4. The landfill owner or operator must demonstrate that 
surface methane emissions are below 500 parts per million. Surface 
emission monitoring must be conducted on a quarterly basis using the 
following procedures. Tier 4 is allowed only if the landfill owner or 
operator can demonstrate that NMOC emissions are greater than or equal 
to 34 Mg/yr but less than 50 Mg/yr using Tier 1 or Tier 2. If both Tier 
1 and Tier 2 indicate NMOC emissions are 50 Mg/yr or greater, then Tier 
4 cannot be used. In addition, the landfill must meet the criteria in 
paragraph (a)(6)(viii) of this section.
    (i) The owner or operator must measure surface concentrations of 
methane along the entire perimeter of the landfill and along a pattern 
that traverses the landfill at no more than 30-meter intervals using an 
organic vapor analyzer, flame ionization detector, or other portable 
monitor meeting the specifications provided in Sec. 60.36f(d).
    (ii) The background concentration must be determined by moving the 
probe inlet upwind and downwind at least 30 meters from the waste mass 
boundary of the landfill.
    (iii) Surface emission monitoring must be performed in accordance 
with section 8.3.1 of Method 21 of appendix A of this part, except that 
the probe inlet must be placed no more than 5 centimeters above the 
landfill surface; the constant measurement of distance above the surface 
should be based on a mechanical device such as with a wheel on a pole.
    (A) The owner or operator must use a wind barrier, similar to a 
funnel, when onsite average wind speed exceeds 4 miles per hour or 2 
meters per second or gust exceeding 10 miles per hour. Average on-site 
wind speed must also be determined in an open area at 5-minute intervals 
using an on-site anemometer with a continuous recorder and data logger 
for the entire duration of the monitoring event. The wind barrier must 
surround the SEM monitor, and must be placed on the ground, to ensure 
wind turbulence is blocked. SEM cannot be conducted if average wind 
speed exceeds 25 miles per hour.
    (B) Landfill surface areas where visual observations indicate 
elevated concentrations of landfill gas, such as distressed vegetation 
and cracks or seeps in the cover, and all cover penetrations must also 
be monitored using a device meeting the specifications provided in Sec. 
60.36f(d).
    (iv) Each owner or operator seeking to comply with the Tier 4 
provisions in paragraph (a)(6) of this section must maintain records of 
surface emission

[[Page 137]]

monitoring as provided in Sec. 60.39f(g) and submit a Tier 4 surface 
emissions report as provided in Sec. 60.38f(d)(4)(iii).
    (v) If there is any measured concentration of methane of 500 parts 
per million or greater from the surface of the landfill, the owner or 
operator must submit a gas collection and control system design plan 
within 1 year of the first measured concentration of methane of 500 
parts per million or greater from the surface of the landfill according 
to Sec. 60.38f(d) and install and operate a gas collection and control 
system according to Sec. 60.33f(b) and (c) within 30 months of the most 
recent NMOC emission rate report in which the NMOC emission rate equals 
or exceeds 34 megagrams per year based on Tier 2.
    (vi) If after four consecutive quarterly monitoring periods at a 
landfill, other than a closed landfill, there is no measured 
concentration of methane of 500 parts per million or greater from the 
surface of the landfill, the owner or operator must continue quarterly 
surface emission monitoring using the methods specified in this section.
    (vii) If after four consecutive quarterly monitoring periods at a 
closed landfill there is no measured concentration of methane of 500 
parts per million or greater from the surface of the landfill, the owner 
or operator must conduct annual surface emission monitoring using the 
methods specified in this section.
    (viii) If a landfill has installed and operates a collection and 
control system that is not required by this subpart, then the collection 
and control system must meet the following criteria:
    (A) The gas collection and control system must have operated for at 
least 6,570 out of 8,760 hours preceding the Tier 4 surface emissions 
monitoring demonstration.
    (B) During the Tier 4 surface emissions monitoring demonstration, 
the gas collection and control system must operate as it normally would 
to collect and control as much landfill gas as possible.
    (b) After the installation and startup of a collection and control 
system in compliance with this subpart, the owner or operator must 
calculate the NMOC emission rate for purposes of determining when the 
system can be capped, removed, or decommissioned as provided in Sec. 
60.33f(f), using Equation 3:
[GRAPHIC] [TIFF OMITTED] TR29AU16.002

Where:

MNMOC = Mass emission rate of NMOC, megagrams per year.
QLFG = Flow rate of landfill gas, cubic meters per minute.
CNMOC = NMOC concentration, parts per million by volume as 
          hexane.

    (1) The flow rate of landfill gas, QLFG, must be 
determined by measuring the total landfill gas flow rate at the common 
header pipe that leads to the control system using a gas flow measuring 
device calibrated according to the provisions of section 10 of Method 2E 
of appendix A of this part.
    (2) The average NMOC concentration, CNMOC, must be 
determined by collecting and analyzing landfill gas sampled from the 
common header pipe before the gas moving or condensate removal equipment 
using the procedures in Method 25 or Method 25C of appendix A of this 
part. The sample location on the common header pipe must be before any 
condensate removal or other gas refining units. The landfill owner or 
operator must divide the NMOC concentration from Method 25 or Method 25C 
by six to convert from CNMOC as carbon to CNMOC as 
hexane.
    (3) The owner or operator may use another method to determine 
landfill gas flow rate and NMOC concentration if the method has been 
approved by the Administrator.
    (i) Within 60 days after the date of calculating the NMOC emission 
rate for purposes of determining when the system can be capped or 
removed, the owner or operator must submit the results according to 
Sec. 60.38f(j)(2).
    (ii) [Reserved]

[[Page 138]]

    (c) When calculating emissions for Prevention of Significant 
Deterioration purposes, the owner or operator of each MSW landfill 
subject to the provisions of this subpart must estimate the NMOC 
emission rate for comparison to the Prevention of Significant 
Deterioration major source and significance levels in Sec. 51.166 or 
Sec. 52.21 of this chapter using Compilation of Air Pollutant Emission 
Factors, Volume I: Stationary Point and Area Sources (AP-42) or other 
approved measurement procedures.
    (d) For the performance test required in Sec. 60.33f(c)(1), the net 
heating value of the combusted landfill gas as determined in Sec. 
60.18(f)(3) is calculated from the concentration of methane in the 
landfill gas as measured by Method 3C. A minimum of three 30-minute 
Method 3C samples are determined. The measurement of other organic 
components, hydrogen, and carbon monoxide is not applicable. Method 3C 
may be used to determine the landfill gas molecular weight for 
calculating the flare gas exit velocity under Sec. 60.18(f)(4).
    (1) Within 60 days after the date of completing each performance 
test (as defined in Sec. 60.8), the owner or operator must submit the 
results of the performance tests required by paragraph (b) or (d) of 
this section, including any associated fuel analyses, according to Sec. 
60.38f(j)(1).
    (2) [Reserved]
    (e) For the performance test required in Sec. 60.33f(c)(2), Method 
25 or 25C (Method 25C may be used at the inlet only) of appendix A of 
this part must be used to determine compliance with the 98 weight-
percent efficiency or the 20 parts per million by volume outlet NMOC 
concentration level, unless another method to demonstrate compliance has 
been approved by the Administrator as provided by Sec. 60.38f(d)(2). 
Method 3, 3A, or 3C must be used to determine oxygen for correcting the 
NMOC concentration as hexane to 3 percent. In cases where the outlet 
concentration is less than 50 ppm NMOC as carbon (8 ppm NMOC as hexane), 
Method 25A should be used in place of Method 25. Method 18 may be used 
in conjunction with Method 25A on a limited basis (compound specific, 
e.g., methane) or Method 3C may be used to determine methane. The 
methane as carbon should be subtracted from the Method 25A total 
hydrocarbon value as carbon to give NMOC concentration as carbon. The 
landfill owner or operator must divide the NMOC concentration as carbon 
by 6 to convert the CNMOC as carbon to CNMOC as 
hexane. Equation 4 must be used to calculate efficiency:
[GRAPHIC] [TIFF OMITTED] TR29AU16.003

Where:

NMOCin = Mass of NMOC entering control device.
NMOCout = Mass of NMOC exiting control device.

    (1) Within 60 days after the date of completing each performance 
test (as defined in Sec. 60.8), the owner or operator must submit the 
results of the performance tests, including any associated fuel 
analyses, according to Sec. 60.38f(j)(1).
    (2) [Reserved]



Sec. 60.36f  Compliance provisions.

    For approval, a state plan must include the compliance provisions in 
this section (as well as the provisions in Sec. Sec. 60.34f and 
60.37f), or the compliance provisions in Sec. 63.1960 of this chapter 
(as well as the provisions in Sec. Sec. 63.1958 of this chapter and 
63.1961 of this chapter), or both as alternative means of compliance, 
for an MSW landfill with a gas collection and control system used to 
comply with the provisions of Sec. 60.33f(b) and (c). Once the owner or 
operator begins to comply with the provisions of Sec. 63.1960 of this 
chapter, the owner or operator must continue to operate the collection 
and control device according to those provisions and cannot return to 
the provisions of this section.
    (a) Except as provided in Sec. 60.38f(d)(2), the specified methods 
in paragraphs (a)(1) through (6) of this section must be used to 
determine whether the gas

[[Page 139]]

collection system is in compliance with Sec. 60.33f(b)(2).
    (1) For the purposes of calculating the maximum expected gas 
generation flow rate from the landfill to determine compliance with 
Sec. 60.33f(b)(2)(i), either Equation 5 or Equation 6 in paragraph 
(a)(1)(i) or (ii) of this section must be used. The methane generation 
rate constant (k) and methane generation potential (Lo) 
kinetic factors should be those published in the most recent AP-42 or 
other site-specific values demonstrated to be appropriate and approved 
by the Administrator. If k has been determined as specified in Sec. 
60.35f(a)(4), the value of k determined from the test must be used. A 
value of no more than 15 years must be used for the intended use period 
of the gas mover equipment. The active life of the landfill is the age 
of the landfill plus the estimated number of years until closure.
    (i) For sites with unknown year-to-year solid waste acceptance rate:
    [GRAPHIC] [TIFF OMITTED] TR29AU16.004
    
Where:

Qm = Maximum expected gas generation flow rate, cubic meters 
          per year.
Lo = Methane generation potential, cubic meters per megagram 
          solid waste.
R = Average annual acceptance rate, megagrams per year.
k = Methane generation rate constant, year-1.
t = Age of the landfill at equipment installation plus the time the 
          owner or operator intends to use the gas mover equipment or 
          active life of the landfill, whichever is less. If the 
          equipment is installed after closure, t is the age of the 
          landfill at installation, years.
c = Time since closure, years (for an active landfill c = 0 and 
          e-kc = 1).

    (ii) For sites with known year-to-year solid waste acceptance rate:
    [GRAPHIC] [TIFF OMITTED] TR29AU16.005
    
Where:

QM = Maximum expected gas generation flow rate, cubic meters 
          per year.
k = Methane generation rate constant, year-1.
Lo = Methane generation potential, cubic meters per megagram 
          solid waste.
Mi = Mass of solid waste in the i\th\ section, megagrams.
ti = Age of the i\th\ section, years.

    (iii) If a collection and control system has been installed, actual 
flow data may be used to project the maximum expected gas generation 
flow rate instead of, or in conjunction with, Equation 5 or Equation 6 
in paragraph (a)(1)(i) or (ii) of this section. If the landfill is still 
accepting waste, the actual measured flow data will not equal the 
maximum expected gas generation rate, so calculations using Equation 5 
or Equation 6 or other methods must be used to predict the maximum 
expected gas generation rate over the intended period of use of the gas 
control system equipment.
    (2) For the purposes of determining sufficient density of gas 
collectors for compliance with Sec. 60.33f(b)(2)(ii), the owner or 
operator must design a system of vertical wells, horizontal collectors, 
or other collection devices, satisfactory to the Administrator, capable 
of controlling and extracting gas from all portions of the landfill 
sufficient to meet all operational and performance standards.
    (3) For the purpose of demonstrating whether the gas collection 
system flow rate is sufficient to determine compliance with Sec. 
60.33f(b)(2)(iii), the owner or operator must measure gauge pressure in 
the gas collection header applied to

[[Page 140]]

each individual well monthly. If a positive pressure exists, action must 
be initiated to correct the exceedance within 5 calendar days, except 
for the three conditions allowed under Sec. 60.34f(b). Any attempted 
corrective measure must not cause exceedances of other operational or 
performance standards.
    (i) If negative pressure cannot be achieved without excess air 
infiltration within 15 calendar days of the first measurement of 
positive pressure, the owner or operator must conduct a root cause 
analysis and correct the exceedance as soon as practicable, but not 
later than 60 days after positive pressure was first measured. The owner 
or operator must keep records according to Sec. 60.39f(e)(3).
    (ii) If corrective actions cannot be fully implemented within 60 
days following the positive pressure or elevated temperature measurement 
for which the root cause analysis was required, the owner or operator 
must also conduct a corrective action analysis and develop an 
implementation schedule to complete the corrective action(s) as soon as 
practicable, but no more than 120 days following the measurement of 
landfill gas temperature greater than 55 degrees Celsius (131 degrees 
Fahrenheit) or positive pressure. The owner or operator must submit the 
items listed in Sec. 60.38f(h)(7) as part of the next annual report. 
The owner or operator must keep records according to Sec. 60.39f(e)(4).
    (iii) If corrective action is expected to take longer than 120 days 
to complete after the initial exceedance, the owner or operator must 
submit the root cause analysis, corrective action analysis, and 
corresponding implementation timeline to the Administrator, according to 
Sec. 60.38f(h)(7) and (k). The owner or operator must keep records 
according to Sec. 60.39f(e)(5).
    (4) [Reserved]
    (5) For the purpose of identifying whether excess air infiltration 
into the landfill is occurring, the owner or operator must monitor each 
well monthly for temperature as provided in Sec. 60.34f(c). If a well 
exceeds the operating parameter for temperature, action must be 
initiated to correct the exceedance within 5 calendar days. Any 
attempted corrective measure must not cause exceedances of other 
operational or performance standards.
    (i) If a landfill gas temperature less than 55 degrees Celsius (131 
degrees Fahrenheit) cannot be achieved within 15 calendar days of the 
first measurement of landfill gas temperature greater than 55 degrees 
Celsius (131 degrees Fahrenheit), the owner or operator must conduct a 
root cause analysis and correct the exceedance as soon as practicable, 
but no later than 60 days after a landfill gas temperature greater than 
55 degrees Celsius (131 degrees Fahrenheit) was first measured. The 
owner or operator must keep records according to Sec. 60.39f(e)(3).
    (ii) If corrective actions cannot be fully implemented within 60 
days following the positive pressure measurement for which the root 
cause analysis was required, the owner or operator must also conduct a 
corrective action analysis and develop an implementation schedule to 
complete the corrective action(s) as soon as practicable, but no more 
than 120 days following the measurement of landfill gas temperature 
greater than 55 degrees Celsius (131 degrees Fahrenheit). The owner or 
operator must submit the items listed in Sec. 60.38f(h)(7) as part of 
the next annual report. The owner or operator must keep records 
according to Sec. 60.39f(e)(4).
    (iii) If corrective action is expected to take longer than 120 days 
to complete after the initial exceedance, the owner or operator must 
submit the root cause analysis, corrective action analysis, and 
corresponding implementation timeline to the Administrator, according to 
Sec. 60.38f(h)(7) and (k). The owner or operator must keep records 
according to Sec. 60.39f(e)(5).
    (6) An owner or operator seeking to demonstrate compliance with 
Sec. 60.33f(b)(2)(iv) through the use of a collection system not 
conforming to the specifications provided in Sec. 60.40f must provide 
information satisfactory to the Administrator as specified in Sec. 
60.38f(d)(3) demonstrating that off-site migration is being controlled.
    (b) For purposes of compliance with Sec. 60.34f(a), each owner or 
operator of a controlled landfill must place each well or design 
component as specified in the approved design plan as provided in

[[Page 141]]

Sec. 60.38f(d). Each well must be installed no later than 60 days after 
the date on which the initial solid waste has been in place for a period 
of:
    (1) Five (5) years or more if active; or
    (2) Two (2) years or more if closed or at final grade.
    (c) The following procedures must be used for compliance with the 
surface methane operational standard as provided in Sec. 60.34f(d):
    (1) After installation and startup of the gas collection system, the 
owner or operator must monitor surface concentrations of methane along 
the entire perimeter of the collection area and along a pattern that 
traverses the landfill at no more than 30-meter intervals (or a site-
specific established spacing) for each collection area on a quarterly 
basis using an organic vapor analyzer, flame ionization detector, or 
other portable monitor meeting the specifications provided in paragraph 
(d) of this section.
    (2) The background concentration must be determined by moving the 
probe inlet upwind and downwind outside the boundary of the landfill at 
a distance of at least 30 meters from the perimeter wells.
    (3) Surface emission monitoring must be performed in accordance with 
section 8.3.1 of Method 21 of appendix A of this part, except that the 
probe inlet must be placed within 5 to 10 centimeters of the ground. 
Monitoring must be performed during typical meteorological conditions.
    (4) Any reading of 500 parts per million or more above background at 
any location must be recorded as a monitored exceedance and the actions 
specified in paragraphs (c)(4)(i) through (v) of this section must be 
taken. As long as the specified actions are taken, the exceedance is not 
a violation of the operational requirements of Sec. 60.34f(d).
    (i) The location of each monitored exceedance must be marked and the 
location and concentration recorded. For location, you must determine 
the latitude and longitude coordinates using an instrument with an 
accuracy of at least 4 meters. The coordinates must be in decimal 
degrees with at least five decimal places.
    (ii) Cover maintenance or adjustments to the vacuum of the adjacent 
wells to increase the gas collection in the vicinity of each exceedance 
must be made and the location must be re-monitored within 10 calendar 
days of detecting the exceedance.
    (iii) If the re-monitoring of the location shows a second 
exceedance, additional corrective action must be taken and the location 
must be monitored again within 10 days of the second exceedance. If the 
re-monitoring shows a third exceedance for the same location, the action 
specified in paragraph (c)(4)(v) of this section must be taken, and no 
further monitoring of that location is required until the action 
specified in paragraph (c)(4)(v) of this section has been taken.
    (iv) Any location that initially showed an exceedance but has a 
methane concentration less than 500 parts per million methane above 
background at the 10-day re-monitoring specified in paragraph (c)(4)(ii) 
or (iii) of this section must be re-monitored 1 month from the initial 
exceedance. If the 1-month re-monitoring shows a concentration less than 
500 parts per million above background, no further monitoring of that 
location is required until the next quarterly monitoring period. If the 
1-month re-monitoring shows an exceedance, the actions specified in 
paragraph (c)(4)(iii) or (v) of this section must be taken.
    (v) For any location where monitored methane concentration equals or 
exceeds 500 parts per million above background three times within a 
quarterly period, a new well or other collection device must be 
installed within 120 calendar days of the initial exceedance. An 
alternative remedy to the exceedance, such as upgrading the blower, 
header pipes or control device, and a corresponding timeline for 
installation may be submitted to the Administrator for approval.
    (5) The owner or operator must implement a program to monitor for 
cover integrity and implement cover repairs as necessary on a monthly 
basis.
    (d) Each owner or operator seeking to comply with the provisions in 
paragraph (c) of this section or Sec. 60.35f(a)(6)

[[Page 142]]

must comply with the following instrumentation specifications and 
procedures for surface emission monitoring devices:
    (1) The portable analyzer must meet the instrument specifications 
provided in section 6 of Method 21 of appendix A of this part, except 
that ``methane'' replaces all references to ``VOC''.
    (2) The calibration gas must be methane, diluted to a nominal 
concentration of 500 parts per million in air.
    (3) To meet the performance evaluation requirements in section 8.1 
of Method 21 of appendix A of this part, the instrument evaluation 
procedures of section 8.1 of Method 21 must be used.
    (4) The calibration procedures provided in sections 8 and 10 of 
Method 21 of appendix A of this part must be followed immediately before 
commencing a surface monitoring survey.
    (e) The provisions of this subpart apply at all times, including 
periods of startup, shutdown, or malfunction. During periods of startup, 
shutdown, and malfunction, you must comply with the work practice 
specified in Sec. 60.34f(e) in lieu of the compliance provisions in 
Sec. 60.36f.

Sec. 60.37f  Monitoring of operations.

    For approval, a state plan must include the monitoring provisions in 
this section, (as well as the provisions in Sec. Sec. 60.34f and 
60.36f) except as provided in Sec. 60.38f(d)(2), or the monitoring 
provisions in Sec. 63.1961 of this chapter (as well as the provisions 
in Sec. Sec. 63.1958 of this chapter and 63.1960 of this chapter), or 
both as alternative means of compliance, for an MSW landfill with a gas 
collection and control system used to comply with the provisions of 
Sec. 60.33f(b) and (c). Once the owner or operator begins to comply 
with the provisions of Sec. 63.1961 of this chapter, the owner or 
operator must continue to operate the collection and control device 
according to those provisions and cannot return to the provisions of 
this section.
    (a) Each owner or operator seeking to comply with Sec. 60.33f(b)(2) 
for an active gas collection system must install a sampling port and a 
thermometer, other temperature measuring device, or an access port for 
temperature measurements at each wellhead and:
    (1) Measure the gauge pressure in the gas collection header on a 
monthly basis as provided in Sec. 60.36f(a)(3); and
    (2) Monitor nitrogen or oxygen concentration in the landfill gas on 
a monthly basis as follows:
    (i) The nitrogen level must be determined using Method 3C, unless an 
alternative test method is established as allowed by Sec. 60.38f(d)(2).
    (ii) Unless an alternative test method is established as allowed by 
Sec. 60.38f(d)(2), the oxygen level must be determined by an oxygen 
meter using Method 3A, 3C, or ASTM D6522-11 (incorporated by reference, 
see Sec. 60.17). Determine the oxygen level by an oxygen meter using 
Method 3A, 3C, or ASTM D6522-11 (if sample location is prior to 
combustion) except that:
    (A) The span must be set between 10 and 12 percent oxygen;
    (B) A data recorder is not required;
    (C) Only two calibration gases are required, a zero and span;
    (D) A calibration error check is not required; and
    (E) The allowable sample bias, zero drift, and calibration drift are 
10 percent.
    (iii) A portable gas composition analyzer may be used to monitor the 
oxygen levels provided:
    (A) The analyzer is calibrated; and
    (B) The analyzer meets all quality assurance and quality control 
requirements for Method 3A or ASTM D6522-11 (incorporated by reference, 
see Sec. 60.17).
    (3) Monitor temperature of the landfill gas on a monthly basis as 
provided in Sec. 60.36f(a)(5). The temperature measuring device must be 
calibrated annually using the procedure in this part 60, appendix A-1, 
Method 2, Section 10.3.
    (b) Each owner or operator seeking to comply with Sec. 60.33f(c) 
using an enclosed combustor must calibrate, maintain, and operate 
according to the manufacturer's specifications, the following equipment:
    (1) A temperature monitoring device equipped with a continuous 
recorder and having a minimum accuracy of 1 
percent of the temperature being measured expressed in degrees Celsius 
or 0.5 degrees Celsius, whichever is greater. A 
temperature monitoring device is

[[Page 143]]

not required for boilers or process heaters with design heat input 
capacity equal to or greater than 44 megawatts.
    (2) A device that records flow to the control device and bypass of 
the control device (if applicable). The owner or operator must:
    (i) Install, calibrate, and maintain a gas flow rate measuring 
device that must record the flow to the control device at least every 15 
minutes; and
    (ii) Secure the bypass line valve in the closed position with a car-
seal or a lock-and-key type configuration. A visual inspection of the 
seal or closure mechanism must be performed at least once every month to 
ensure that the valve is maintained in the closed position and that the 
gas flow is not diverted through the bypass line.
    (c) Each owner or operator seeking to comply with Sec. 60.33f(c) 
using a non-enclosed flare must install, calibrate, maintain, and 
operate according to the manufacturer's specifications the following 
equipment:
    (1) A heat sensing device, such as an ultraviolet beam sensor or 
thermocouple, at the pilot light or the flame itself to indicate the 
continuous presence of a flame.
    (2) A device that records flow to the flare and bypass of the flare 
(if applicable). The owner or operator must:
    (i) Install, calibrate, and maintain a gas flow rate measuring 
device that records the flow to the control device at least every 15 
minutes; and
    (ii) Secure the bypass line valve in the closed position with a car-
seal or a lock-and-key type configuration. A visual inspection of the 
seal or closure mechanism must be performed at least once every month to 
ensure that the valve is maintained in the closed position and that the 
gas flow is not diverted through the bypass line.
    (d) Each owner or operator seeking to demonstrate compliance with 
Sec. 60.33f(c) using a device other than a non-enclosed flare or an 
enclosed combustor or a treatment system must provide information 
satisfactory to the Administrator as provided in Sec. 60.38f(d)(2) 
describing the operation of the control device, the operating parameters 
that would indicate proper performance, and appropriate monitoring 
procedures. The Administrator must review the information and either 
approve it, or request that additional information be submitted. The 
Administrator may specify additional appropriate monitoring procedures.
    (e) Each owner or operator seeking to install a collection system 
that does not meet the specifications in Sec. 60.40f or seeking to 
monitor alternative parameters to those required by Sec. Sec. 60.34f 
through 60.37f must provide information satisfactory to the 
Administrator as provided in Sec. 60.38f(d)(2) and (3) describing the 
design and operation of the collection system, the operating parameters 
that would indicate proper performance, and appropriate monitoring 
procedures. The Administrator may specify additional appropriate 
monitoring procedures.
    (f) Each owner or operator seeking to demonstrate compliance with 
the 500 parts per million surface methane operational standard in Sec. 
60.34f(d) must monitor surface concentrations of methane according to 
the procedures provided in Sec. 60.36f(c) and the instrument 
specifications in Sec. 60.36f(d). Any closed landfill that has no 
monitored exceedances of the operational standard in three consecutive 
quarterly monitoring periods may skip to annual monitoring. Any methane 
reading of 500 parts per million or more above background detected 
during the annual monitoring returns the frequency for that landfill to 
quarterly monitoring.
    (g) Each owner or operator seeking to demonstrate compliance with 
the control system requirements in Sec. 60.33f(c) using a landfill gas 
treatment system must maintain and operate all monitoring systems 
associated with the treatment system in accordance with the site-
specific treatment system monitoring plan required in Sec. 
60.39f(b)(5)(ii) and must calibrate, maintain, and operate according to 
the manufacturer's specifications a device that records flow to the 
treatment system and bypass of the treatment system (if applicable). The 
owner or operator must:
    (1) Install, calibrate, and maintain a gas flow rate measuring 
device that records the flow to the treatment system at least every 15 
minutes; and
    (2) Secure the bypass line valve in the closed position with a car-
seal or a

[[Page 144]]

lock-and-key type configuration. A visual inspection of the seal or 
closure mechanism must be performed at least once every month to ensure 
that the valve is maintained in the closed position and that the gas 
flow is not diverted through the bypass line.
    (h) The monitoring requirements of paragraphs (b), (c) (d) and (g) 
of this section apply at all times the affected source is operating, 
except for periods of monitoring system malfunctions, repairs associated 
with monitoring system malfunctions, and required monitoring system 
quality assurance or quality control activities. A monitoring system 
malfunction is any sudden, infrequent, not reasonably preventable 
failure of the monitoring system to provide valid data. Monitoring 
system failures that are caused in part by poor maintenance or careless 
operation are not malfunctions. You are required to complete monitoring 
system repairs in response to monitoring system malfunctions and to 
return the monitoring system to operation as expeditiously as 
practicable.

Sec. 60.38f  Reporting guidelines.

    For approval, a state plan must include the reporting provisions 
listed in this section, as applicable, except as provided under 
Sec. Sec. 60.24 and 60.38f(d)(2).
    (a) Design capacity report. For existing MSW landfills subject to 
this subpart, the initial design capacity report must be submitted no 
later than 90 days after the effective date of EPA approval of the 
state's plan under section 111(d) of the Clean Air Act. The initial 
design capacity report must contain the following information:
    (1) A map or plot of the landfill, providing the size and location 
of the landfill, and identifying all areas where solid waste may be 
landfilled according to the permit issued by the state, local, or tribal 
agency responsible for regulating the landfill.
    (2) The maximum design capacity of the landfill. Where the maximum 
design capacity is specified in the permit issued by the state, local, 
or tribal agency responsible for regulating the landfill, a copy of the 
permit specifying the maximum design capacity may be submitted as part 
of the report. If the maximum design capacity of the landfill is not 
specified in the permit, the maximum design capacity must be calculated 
using good engineering practices. The calculations must be provided, 
along with the relevant parameters as part of the report. The landfill 
may calculate design capacity in either megagrams or cubic meters for 
comparison with the exemption values. If the owner or operator chooses 
to convert the design capacity from volume to mass or from mass to 
volume to demonstrate its design capacity is less than 2.5 million 
megagrams or 2.5 million cubic meters, the calculation must include a 
site-specific density, which must be recalculated annually. Any density 
conversions must be documented and submitted with the design capacity 
report. The state, local, or tribal agency or the Administrator may 
request other reasonable information as may be necessary to verify the 
maximum design capacity of the landfill.
    (b) Amended design capacity report. An amended design capacity 
report must be submitted providing notification of an increase in the 
design capacity of the landfill, within 90 days of an increase in the 
maximum design capacity of the landfill to meet or exceed 2.5 million 
megagrams and 2.5 million cubic meters. This increase in design capacity 
may result from an increase in the permitted volume of the landfill or 
an increase in the density as documented in the annual recalculation 
required in Sec. 60.39f(f).
    (c) NMOC emission rate report. For existing MSW landfills covered by 
this subpart with a design capacity equal to or greater than 2.5 million 
megagrams and 2.5 million cubic meters, the NMOC emission rate report 
must be submitted following the procedure specified in paragraph (j)(2) 
of this section no later than 90 days after the effective date of EPA 
approval of the state's plan under section 111(d) of the Clean Air Act. 
The NMOC emission rate report must be submitted to the Administrator 
annually following the procedure specified in paragraph (j)(2) of this 
section, except as provided for in paragraph (c)(3) of this section. The 
Administrator may request such additional information as

[[Page 145]]

may be necessary to verify the reported NMOC emission rate.
    (1) The NMOC emission rate report must contain an annual or 5-year 
estimate of the NMOC emission rate calculated using the formula and 
procedures provided in Sec. 60.35f(a) or (b), as applicable.
    (2) The NMOC emission rate report must include all the data, 
calculations, sample reports and measurements used to estimate the 
annual or 5-year emissions.
    (3) If the estimated NMOC emission rate as reported in the annual 
report to the Administrator is less than 34 megagrams per year in each 
of the next 5 consecutive years, the owner or operator may elect to 
submit, following the procedure specified in paragraph (j)(2) of this 
section, an estimate of the NMOC emission rate for the next 5-year 
period in lieu of the annual report. This estimate must include the 
current amount of solid waste-in-place and the estimated waste 
acceptance rate for each year of the 5 years for which an NMOC emission 
rate is estimated. All data and calculations upon which this estimate is 
based must be provided to the Administrator. This estimate must be 
revised at least once every 5 years. If the actual waste acceptance rate 
exceeds the estimated waste acceptance rate in any year reported in the 
5-year estimate, a revised 5-year estimate must be submitted to the 
Administrator. The revised estimate must cover the 5-year period 
beginning with the year in which the actual waste acceptance rate 
exceeded the estimated waste acceptance rate.
    (4) Each owner or operator subject to the requirements of this 
subpart is exempted from the requirements to submit an NMOC emission 
rate report, after installing a collection and control system that 
complies with Sec. 60.33f(b) and (c), during such time as the 
collection and control system is in operation and in compliance with 
Sec. Sec. 60.34f and 60.36f.
    (d) Collection and control system design plan. The state plan must 
include a process for state review and approval of the site-specific 
design plan for each gas collection and control system. The collection 
and control system design plan must be prepared and approved by a 
professional engineer and must meet the following requirements:
    (1) The collection and control system as described in the design 
plan must meet the design requirements in Sec. 60.33f(b) and (c).
    (2) The collection and control system design plan must include any 
alternatives to the operational standards, test methods, procedures, 
compliance measures, monitoring, recordkeeping, or reporting provisions 
of Sec. Sec. 60.34f through 60.39f proposed by the owner or operator.
    (3) The collection and control system design plan must either 
conform to specifications for active collection systems in Sec. 60.40f 
or include a demonstration to the Administrator's satisfaction of the 
sufficiency of the alternative provisions to Sec. 60.40f.
    (4) Each owner or operator of an MSW landfill having a design 
capacity equal to or greater than 2.5 million megagrams and 2.5 million 
cubic meters must submit a copy of the collection and control system 
design plan cover page that contains the engineer's seal to the 
Administrator within 1 year of the first NMOC emission rate report in 
which the NMOC emission rate equals or exceeds 34 megagrams per year, 
except as follows:
    (i) If the owner or operator elects to recalculate the NMOC emission 
rate after Tier 2 NMOC sampling and analysis as provided in Sec. 
60.35f(a)(3) and the resulting rate is less than 34 megagrams per year, 
annual periodic reporting must be resumed, using the Tier 2 determined 
site-specific NMOC concentration, until the calculated NMOC emission 
rate is equal to or greater than 34 megagrams per year or the landfill 
is closed. The revised NMOC emission rate report, with the recalculated 
NMOC emission rate based on NMOC sampling and analysis, must be 
submitted, following the procedures in paragraph (j)(2) of this section, 
within 180 days of the first calculated exceedance of 34 megagrams per 
year.
    (ii) If the owner or operator elects to recalculate the NMOC 
emission rate after determining a site-specific methane generation rate 
constant k, as provided in Tier 3 in Sec. 60.35f(a)(4), and the 
resulting NMOC emission rate is less than 34 megagrams per year, annual

[[Page 146]]

periodic reporting must be resumed. The resulting site-specific methane 
generation rate constant k must be used in the NMOC emission rate 
calculation until such time as the emissions rate calculation results in 
an exceedance. The revised NMOC emission rate report based on the 
provisions of Sec. 60.35f(a)(4) and the resulting site-specific methane 
generation rate constant k must be submitted, following the procedure 
specified in paragraph (j)(2) of this section, to the Administrator 
within 1 year of the first calculated NMOC emission rate equaling or 
exceeding 34 megagrams per year.
    (iii) If the owner or operator elects to demonstrate that site-
specific surface methane emissions are below 500 parts per million 
methane, based on the provisions of Sec. 60.35f(a)(6), then the owner 
or operator must submit annually a Tier 4 surface emissions report as 
specified in this paragraph (d)(4)(iii) following the procedure 
specified in paragraph (j)(2) of this section until a surface emissions 
readings of 500 parts per million methane or greater is found. If the 
Tier 4 surface emissions report shows no surface emissions readings of 
500 parts per million methane or greater for four consecutive quarters 
at a closed landfill, then the landfill owner or operator may reduce 
Tier 4 monitoring from a quarterly to an annual frequency. The 
Administrator may request such additional information as may be 
necessary to verify the reported instantaneous surface emission 
readings. The Tier 4 surface emissions report must clearly identify the 
location, date and time (to the nearest second), average wind speeds 
including wind gusts, and reading (in parts per million) of any value 
500 parts per million methane or greater, other than non-repeatable, 
momentary readings. For location, you must determine the latitude and 
longitude coordinates using an instrument with an accuracy of at least 4 
meters. The coordinates must be in decimal degrees with at least five 
decimal places. The Tier 4 surface emission report should also include 
the results of the most recent Tier 1 and Tier 2 results in order to 
verify that the landfill does not exceed 50 Mg/yr of NMOC.
    (A) The initial Tier 4 surface emissions report must be submitted 
annually, starting within 30 days of completing the fourth quarter of 
Tier 4 surface emissions monitoring that demonstrates that site-specific 
surface methane emissions are below 500 parts per million methane, and 
following the procedure specified in paragraph (j)(2) of this section.
    (B) The Tier 4 surface emissions rate report must be submitted 
within 1 year of the first measured surface exceedance of 500 parts per 
million methane, following the procedure specified in paragraph (j)(2) 
of this section.
    (iv) If the landfill is in the closed landfill subcategory, the 
owner or operator must submit a collection and control system design 
plan to the Administrator within 1 year of the first NMOC emission rate 
report in which the NMOC emission rate equals or exceeds 50 megagrams 
per year, except as follows:
    (A) If the owner or operator elects to recalculate the NMOC emission 
rate after Tier 2 NMOC sampling and analysis as provided in Sec. 
60.35f(a)(3) and the resulting rate is less than 50 megagrams per year, 
annual periodic reporting must be resumed, using the Tier 2 determined 
site-specific NMOC concentration, until the calculated NMOC emission 
rate is equal to or greater than 50 megagrams per year or the landfill 
is closed. The revised NMOC emission rate report, with the recalculated 
NMOC emission rate based on NMOC sampling and analysis, must be 
submitted, following the procedure specified in paragraph (j)(2) of this 
section, within 180 days of the first calculated exceedance of 50 
megagrams per year.
    (B) If the owner or operator elects to recalculate the NMOC emission 
rate after determining a site-specific methane generation rate constant 
k, as provided in Tier 3 in Sec. 60.35f(a)(4), and the resulting NMOC 
emission rate is less than 50 megagrams per year, annual periodic 
reporting must be resumed. The resulting site-specific methane 
generation rate constant k must be used in the NMOC emission rate 
calculation until such time as the emissions rate calculation results in 
an exceedance. The revised NMOC emission

[[Page 147]]

rate report based on the provisions of Sec. 60.35f(a)(4) and the 
resulting site-specific methane generation rate constant k must be 
submitted, following the procedure specified in paragraph (j)(2) of this 
section, to the Administrator within 1 year of the first calculated NMOC 
emission rate equaling or exceeding 50 megagrams per year.
    (C) The landfill owner or operator elects to demonstrate surface 
emissions are low, consistent with the provisions in paragraph 
(d)(4)(iii) of this section.
    (D) The landfill has already submitted a gas collection and control 
system design plan consistent with the provisions of subpart WWW of this 
part; 40 CFR part 62, subpart GGG; or a state plan implementing subpart 
Cc of this part.
    (5) The landfill owner or operator must notify the Administrator 
that the design plan is completed and submit a copy of the plan's 
signature page. The Administrator has 90 days to decide whether the 
design plan should be submitted for review. If the Administrator chooses 
to review the plan, the approval process continues as described in 
paragraph (c)(6) of this section. However, if the Administrator 
indicates that submission is not required or does not respond within 90 
days, the landfill owner or operator can continue to implement the plan 
with the recognition that the owner or operator is proceeding at their 
own risk. In the event that the design plan is required to be modified 
to obtain approval, the owner or operator must take any steps necessary 
to conform any prior actions to the approved design plan and any failure 
to do so could result in an enforcement action.
    (6) Upon receipt of an initial or revised design plan, the 
Administrator must review the information submitted under paragraphs 
(d)(1) through (3) of this section and either approve it, disapprove it, 
or request that additional information be submitted. Because of the many 
site-specific factors involved with landfill gas system design, 
alternative systems may be necessary. A wide variety of system designs 
are possible, such as vertical wells, combination horizontal and 
vertical collection systems, or horizontal trenches only, leachate 
collection components, and passive systems. If the Administrator does 
not approve or disapprove the design plan, or does not request that 
additional information be submitted within 90 days of receipt, then the 
owner or operator may continue with implementation of the design plan, 
recognizing they would be proceeding at their own risk.
    (7) If the owner or operator chooses to demonstrate compliance with 
the emission control requirements of this subpart using a treatment 
system as defined in this subpart, then the owner or operator must 
prepare a site-specific treatment system monitoring plan as specified in 
Sec. 60.39f(b)(5).
    (e) Revised design plan. The owner or operator who has already been 
required to submit a design plan under paragraph (d) of this section, or 
under subpart WWW of this part; 40 CFR part 62, subpart GGG; or a state 
plan implementing subpart Cc of this part, must submit a revised design 
plan to the Administrator for approval as follows:
    (1) At least 90 days before expanding operations to an area not 
covered by the previously approved design plan.
    (2) Prior to installing or expanding the gas collection system in a 
way that is not consistent with the design plan that was submitted to 
the Administrator according to paragraph (d) of this section.
    (f) Closure report. Each owner or operator of a controlled landfill 
must submit a closure report to the Administrator within 30 days of 
ceasing waste acceptance. The Administrator may request additional 
information as may be necessary to verify that permanent closure has 
taken place in accordance with the requirements of 40 CFR 258.60. If a 
closure report has been submitted to the Administrator, no additional 
wastes may be placed into the landfill without filing a notification of 
modification as described under Sec. 60.7(a)(4).
    (g) Equipment removal report. Each owner or operator of a controlled 
landfill must submit an equipment removal report to the Administrator 30 
days prior to removal or cessation of operation of the control 
equipment.
    (1) The equipment removal report must contain the following items:

[[Page 148]]

    (i) A copy of the closure report submitted in accordance with 
paragraph (f) of this section; and
    (ii) A copy of the initial performance test report demonstrating 
that the 15-year minimum control period has expired, unless the report 
of the results of the performance test has been submitted to the EPA via 
the EPA's CDX, or information that demonstrates that the GCCS will be 
unable to operate for 15 years due to declining gas flows. In the 
equipment removal report, the process unit(s) tested, the pollutant(s) 
tested, and the date that such performance test was conducted may be 
submitted in lieu of the performance test report if the report has been 
previously submitted to the EPA's CDX; and
    (iii) Dated copies of three successive NMOC emission rate reports 
demonstrating that the landfill is no longer producing 34 megagrams or 
greater of NMOC per year, unless the NMOC emission rate reports have 
been submitted to the EPA via the EPA's CDX. If the NMOC emission rate 
reports have been previously submitted to the EPA's CDX, a statement 
that the NMOC emission rate reports have been submitted electronically 
and the dates that the reports were submitted to the EPA's CDX may be 
submitted in the equipment removal report in lieu of the NMOC emission 
rate reports; or
    (iv) For the closed landfill subcategory, dated copies of three 
successive NMOC emission rate reports demonstrating that the landfill is 
no longer producing 50 megagrams or greater of NMOC per year, unless the 
NMOC emission rate reports have been submitted to the EPA via the EPA's 
CDX. If the NMOC emission rate reports have been previously submitted to 
the EPA's CDX, a statement that the NMOC emission rate reports have been 
submitted electronically and the dates that the reports were submitted 
to the EPA's CDX may be submitted in the equipment removal report in 
lieu of the NMOC emission rate reports.
    (2) The Administrator may request such additional information as may 
be necessary to verify that all of the conditions for removal in Sec. 
60.33f(f) have been met.
    (h) Annual report. The owner or operator of a landfill seeking to 
comply with Sec. 60.33f(e)(2) using an active collection system 
designed in accordance with Sec. 60.33f(b) must submit to the 
Administrator, following the procedures specified in paragraph (j)(2) of 
this section, an annual report of the recorded information in paragraphs 
(h)(1) through (7) of this section. The initial annual report must be 
submitted within 180 days of installation and startup of the collection 
and control system. The initial annual report must include the initial 
performance test report required under Sec. 60.8, as applicable, unless 
the report of the results of the performance test has been submitted to 
the EPA via the EPA's CDX. In the initial annual report, the process 
unit(s) tested, the pollutant(s) tested and the date that such 
performance test was conducted may be submitted in lieu of the 
performance test report if the report has been previously submitted to 
the EPA's CDX. The initial performance test report must be submitted, 
following the procedure specified in paragraph (j)(1) of this section, 
no later than the date that the initial annual report is submitted. For 
enclosed combustion devices and flares, reportable exceedances are 
defined under Sec. 60.39f(c)(1). If complying with the operational 
provisions of Sec. Sec. 63.1958, 63.1960, and 63.1961 of this chapter,

Sec. 60.40f  Specifications for active collection systems.

    For approval, a state plan must include the specifications for 
active collection systems in this section.
    (a) Each owner or operator seeking to comply with Sec. 60.33f(b) 
must site active collection wells, horizontal collectors, surface 
collectors, or other extraction devices at a sufficient density 
throughout all gas producing areas using the following procedures unless 
alternative procedures have been approved by the Administrator.
    (1) The collection devices within the interior must be certified to 
achieve comprehensive control of surface gas emissions by a professional 
engineer. The following issues must be addressed in the design: depths 
of refuse, refuse gas generation rates and flow characteristics, cover 
properties, gas system expandability, leachate and condensate 
management, accessibility, compatibility with filling operations, 
integration with closure end use, air intrusion control, corrosion 
resistance, fill settlement, resistance to the refuse decomposition 
heat, and ability to isolate individual components or sections for 
repair or troubleshooting without shutting down entire collection 
system.
    (2) The sufficient density of gas collection devices determined in 
paragraph (a)(1) of this section must address landfill gas migration 
issues and augmentation of the collection system through the use of 
active or passive systems at the landfill perimeter or exterior.
    (3) The placement of gas collection devices determined in paragraph 
(a)(1) of this section must control all gas producing areas, except as 
provided by paragraphs (a)(3)(i) and (ii) of this section.
    (i) Any segregated area of asbestos or nondegradable material may be 
excluded from collection if documented as provided under Sec. 
60.39f(d). The documentation must provide the nature, date of 
deposition, location and amount of asbestos or nondegradable material 
deposited in the area, and must be provided to the Administrator upon 
request.
    (ii) Any nonproductive area of the landfill may be excluded from 
control, provided that the total of all excluded areas can be shown to 
contribute less than 1 percent of the total amount of NMOC emissions 
from the landfill. The amount, location, and age of the material must be 
documented and provided to the Administrator upon request. A separate 
NMOC emissions estimate must be made for each section proposed for 
exclusion, and the sum of all such sections must be compared to the NMOC 
emissions estimate for the entire landfill.
    (A) The NMOC emissions from each section proposed for exclusion must 
be computed using Equation 7:
[GRAPHIC] [TIFF OMITTED] TR29AU16.006

Where:

Qi = NMOC emission rate from the i\th\ section, megagrams per 
          year.
k = Methane generation rate constant, year-1.
Lo = Methane generation potential, cubic meters per megagram 
          solid waste.
Mi = Mass of the degradable solid waste in the i\th\ section, 
          megagram.
ti = Age of the solid waste in the i\th\ section, years.
CNMOC = Concentration of NMOC, parts per million by volume.
3.6x10-9 = Conversion factor.

    (B) If the owner or operator is proposing to exclude, or cease gas 
collection and control from, nonproductive physically separated (e.g., 
separately lined) closed areas that already have gas collection systems, 
NMOC emissions from each physically separated closed area must be 
computed using either Equation 3 in Sec. 60.35f or Equation 7 in 
paragraph (a)(3)(ii)(A) of this section.
    (iii) The values for k and CNMOC determined in field 
testing must be used if

[[Page 156]]

field testing has been performed in determining the NMOC emission rate 
or the radii of influence (the distance from the well center to a point 
in the landfill where the pressure gradient applied by the blower or 
compressor approaches zero). If field testing has not been performed, 
the default values for k, Lo, and CNMOC provided 
in Sec. 60.35f or the alternative values from Sec. 60.35f must be 
used. The mass of nondegradable solid waste contained within the given 
section may be subtracted from the total mass of the section when 
estimating emissions provided the nature, location, age, and amount of 
the nondegradable material is documented as provided in paragraph 
(a)(3)(i) of this section.
    (b) Each owner or operator seeking to comply with Sec. 60.33f(b) 
must construct the gas collection devices using the following equipment 
or procedures:
    (1) The landfill gas extraction components must be constructed of 
polyvinyl chloride (PVC), high density polyethylene (HDPE) pipe, 
fiberglass, stainless steel, or other nonporous corrosion resistant 
material of suitable dimensions to: Convey projected amounts of gases; 
withstand installation, static, and settlement forces; and withstand 
planned overburden or traffic loads. The collection system must extend 
as necessary to comply with emission and migration standards. Collection 
devices such as wells and horizontal collectors must be perforated to 
allow gas entry without head loss sufficient to impair performance 
across the intended extent of control. Perforations must be situated 
with regard to the need to prevent excessive air infiltration.
    (2) Vertical wells must be placed so as not to endanger underlying 
liners and must address the occurrence of water within the landfill. 
Holes and trenches constructed for piped wells and horizontal collectors 
must be of sufficient cross-section so as to allow for their proper 
construction and completion including, for example, centering of pipes 
and placement of gravel backfill. Collection devices must be designed so 
as not to allow indirect short circuiting of air into the cover or 
refuse into the collection system or gas into the air. Any gravel used 
around pipe perforations should be of a dimension so as not to penetrate 
or block perforations.
    (3) Collection devices may be connected to the collection header 
pipes below or above the landfill surface. The connector assembly must 
include a positive closing throttle valve, any necessary seals and 
couplings, access couplings and at least one sampling port. The 
collection devices must be constructed of PVC, HDPE, fiberglass, 
stainless steel, or other nonporous material of suitable thickness.
    (c) Each owner or operator seeking to comply with Sec. 60.33f(c) 
must convey the landfill gas to a control system in compliance with 
Sec. 60.33f(c) through the collection header pipe(s). The gas mover 
equipment must be sized to handle the maximum gas generation flow rate 
expected over the intended use period of the gas moving equipment using 
the following procedures:
    (1) For existing collection systems, the flow data must be used to 
project the maximum flow rate. If no flow data exist, the procedures in 
paragraph (c)(2) of this section must be used.
    (2) For new collection systems, the maximum flow rate must be in 
accordance with Sec. 60.36f(a)(1).

will from then on (unless the unit is modified or reconstructed in the 
future) have to comply with the requirements in Sec. 60.44Da(e)(3) of 
subpart Da of this part.



Sec. 60.45  Emissions and fuel monitoring.

    (a) Each owner or operator of an affected facility subject to the 
applicable emissions standard shall install, calibrate, maintain, and 
operate continuous opacity monitoring system (COMS) for measuring 
opacity and a continuous emissions monitoring system (CEMS) for 
measuring SO2 emissions, NOX emissions, and either 
oxygen (O2) or carbon dioxide (CO2) except as 
provided in paragraph (b) of this section.
    (b) Certain of the CEMS and COMS requirements under paragraph (a) of 
this section do not apply to owners or operators under the following 
conditions:
    (1) For a fossil-fuel-fired steam generator that combusts only 
gaseous or liquid fossil fuel (excluding residual oil) with potential 
SO2 emissions rates of 26 ng/J (0.060 lb/MMBtu) or less and 
that does not use post-combustion technology to reduce emissions of 
SO2 or PM, COMS for measuring the opacity of emissions and 
CEMS for measuring SO2 emissions are not required if the 
owner or operator monitors SO2 emissions by fuel sampling and 
analysis or fuel receipts.
    (2) For a fossil-fuel-fired steam generator that does not use a flue 
gas desulfurization device, a CEMS for measuring SO2 
emissions is not required if the owner or operator monitors 
SO2 emissions by fuel sampling and analysis.
    (3) Notwithstanding Sec. 60.13(b), installation of a CEMS for 
NOX may be delayed until after the initial performance tests 
under Sec. 60.8 have been conducted. If the owner or operator 
demonstrates during the performance test that emissions of 
NOX are less than 70 percent of the applicable standards in 
Sec. 60.44, a CEMS for measuring NOX emissions is not 
required. If the initial performance test results show that 
NOX emissions are greater than 70 percent of the applicable 
standard, the owner or operator shall install a CEMS for NOX 
within one year after the date of the initial performance tests under 
Sec. 60.8 and comply with all other applicable monitoring requirements 
under this part.
    (4) If an owner or operator is not required to and elects not to 
install any CEMS for either SO2 or NOX, a CEMS for 
measuring either O2 or CO2 is not required.
    (5) For affected facilities using a PM CEMS, a bag leak detection 
system to monitor the performance of a fabric filter (baghouse) 
according to the most current requirements in Sec. 60.48Da of this 
part, or an ESP predictive model to monitor the performance of the ESP 
developed in accordance and operated according to the most current 
requirements in section Sec. 60.48Da of this part a COMS is not 
required.
    (6) A COMS for measuring the opacity of emissions is not required 
for an affected facility that does not use post-combustion technology 
(except a wet scrubber) for reducing PM, SO2, or carbon 
monoxide (CO) emissions, burns only gaseous fuels or fuel oils that 
contain less than or equal to 0.30 weight percent sulfur, and is 
operated such that emissions of CO to the atmosphere from the affected 
source are maintained at levels less than or equal to 0.15 lb/MMBtu on a 
boiler operating day average basis. Owners and operators of affected 
sources electing to comply with this paragraph must demonstrate 
compliance according to the procedures specified in paragraphs (b)(6)(i) 
through (iv) of this section.
    (i) You must monitor CO emissions using a CEMS according to the 
procedures specified in paragraphs (b)(6)(i)(A) through (D) of this 
section.

[[Page 163]]

    (A) The CO CEMS must be installed, certified, maintained, and 
operated according to the provisions in Sec. 60.58b(i)(3) of subpart Eb 
of this part.
    (B) Each 1-hour CO emissions average is calculated using the data 
points generated by the CO CEMS expressed in parts per million by volume 
corrected to 3 percent oxygen (dry basis).
    (C) At a minimum, valid 1-hour CO emissions averages must be 
obtained for at least 90 percent of the operating hours on a 30-day 
rolling average basis. The 1-hour averages are calculated using the data 
points required in Sec. 60.13(h)(2).
    (D) Quarterly accuracy determinations and daily calibration drift 
tests for the CO CEMS must be performed in accordance with procedure 1 
in appendix F of this part.
    (ii) You must calculate the 1-hour average CO emissions levels for 
each boiler operating day by multiplying the average hourly CO output 
concentration measured by the CO CEMS times the corresponding average 
hourly flue gas flow rate and divided by the corresponding average 
hourly heat input to the affected source. The 24-hour average CO 
emission level is determined by calculating the arithmetic average of 
the hourly CO emission levels computed for each boiler operating day.
    (iii) You must evaluate the preceding 24-hour average CO emission 
level each boiler operating day excluding periods of affected source 
startup, shutdown, or malfunction. If the 24-hour average CO emission 
level is greater than 0.15 lb/MMBtu, you must initiate investigation of 
the relevant equipment and control systems within 24 hours of the first 
discovery of the high emission incident and, take the appropriate 
corrective action as soon as practicable to adjust control settings or 
repair equipment to reduce the 24-hour average CO emission level to 0.15 
lb/MMBtu or less.
    (iv) You must record the CO measurements and calculations performed 
according to paragraph (b)(6) of this section and any corrective actions 
taken. The record of corrective action taken must include the date and 
time during which the 24-hour average CO emission level was greater than 
0.15 lb/MMBtu, and the date, time, and description of the corrective 
action.
    (7) An owner or operator of an affected facility subject to an 
opacity standard under Sec. 60.42 that elects to not use a COMS because 
the affected facility burns only fuels as specified under paragraph 
(b)(1) of this section, monitors PM emissions as specified under 
paragraph (b)(5) of this section, or monitors CO emissions as specified 
under paragraph (b)(6) of this section, shall conduct a performance test 
using Method 9 of appendix A-4 of this part and the procedures in Sec. 
60.11 to demonstrate compliance with the applicable limit in Sec. 60.42 
by April 29, 2011 or within 45 days after stopping use of an existing 
COMS, whichever is later, and shall comply with either paragraph 
(b)(7)(i), (b)(7)(ii), or (b)(7)(iii) of this section. The observation 
period for Method 9 of appendix A-4 of this part performance tests may 
be reduced from 3 hours to 60 minutes if all 6-minute averages are less 
than 10 percent and all individual 15-second observations are less than 
or equal to 20 percent during the initial 60 minutes of observation. The 
permitting authority may exempt owners or operators of affected 
facilities burning only natural gas from the opacity monitoring 
requirements.
    (i) Except as provided in paragraph (b)(7)(ii) or (b)(7)(iii) of 
this section, the owner or operator shall conduct subsequent Method 9 of 
appendix A-4 of this part performance tests using the procedures in 
paragraph (b)(7) of this section according to the applicable schedule in 
paragraphs (b)(7)(i)(A) through (b)(7)(i)(D) of this section, as 
determined by the most recent Method 9 of appendix A-4 of this part 
performance test results.
    (A) If no visible emissions are observed, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 12 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later;
    (B) If visible emissions are observed but the maximum 6-minute 
average opacity is less than or equal to 5 percent, a subsequent Method 
9 of appendix A-4 of this part performance test must be completed within 
6 calendar

[[Page 164]]

months from the date that the most recent performance test was conducted 
or within 45 days of the next day that fuel with an opacity standard is 
combusted, whichever is later;
    (C) If the maximum 6-minute average opacity is greater than 5 
percent but less than or equal to 10 percent, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 3 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later; or
    (D) If the maximum 6-minute average opacity is greater than 10 
percent, a subsequent Method 9 of appendix A-4 of this part performance 
test must be completed within 45 calendar days from the date that the 
most recent performance test was conducted.
    (ii) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 of this part performance test, elect to perform 
subsequent monitoring using Method 22 of appendix A-7 of this part 
according to the procedures specified in paragraphs (b)(7)(ii)(A) and 
(B) of this section.
    (A) The owner or operator shall conduct 10 minute observations 
(during normal operation) each operating day the affected facility fires 
fuel for which an opacity standard is applicable using Method 22 of 
appendix A-7 of this part and demonstrate that the sum of the 
occurrences of any visible emissions is not in excess of 5 percent of 
the observation period (i.e., 30 seconds per 10 minute period). If the 
sum of the occurrence of any visible emissions is greater than 30 
seconds during the initial 10 minute observation, immediately conduct a 
30 minute observation. If the sum of the occurrence of visible emissions 
is greater than 5 percent of the observation period (i.e., 90 seconds 
per 30 minute period), the owner or operator shall either document and 
adjust the operation of the facility and demonstrate within 24 hours 
that the sum of the occurrence of visible emissions is equal to or less 
than 5 percent during a 30 minute observation (i.e., 90 seconds) or 
conduct a new Method 9 of appendix A-4 of this part performance test 
using the procedures in paragraph (b)(7) of this section within 45 
calendar days according to the requirements in Sec. 60.46(b)(3).
    (B) If no visible emissions are observed for 10 operating days 
during which an opacity standard is applicable, observations can be 
reduced to once every 7 operating days during which an opacity standard 
is applicable. If any visible emissions are observed, daily observations 
shall be resumed.
    (iii) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 performance tests, elect to perform subsequent 
monitoring using a digital opacity compliance system according to a 
site-specific monitoring plan approved by the Administrator. The 
observations shall be similar, but not necessarily identical, to the 
requirements in paragraph (b)(7)(ii) of this section. For reference 
purposes in preparing the monitoring plan, see OAQPS ``Determination of 
Visible Emission Opacity from Stationary Sources Using Computer-Based 
Photographic Analysis Systems.'' This document is available from the 
U.S. Environmental Protection Agency (U.S. EPA); Office of Air Quality 
and Planning Standards; Sector Policies and Programs Division; 
Measurement Policy Group (D243-02), Research Triangle Park, NC 27711. 
This document is also available on the Technology Transfer Network (TTN) 
under Emission Measurement Center Preliminary Methods.
    (8) A COMS for measuring the opacity of emissions is not required 
for an affected facility at which the owner or operator installs, 
calibrates, operates, and maintains a particulate matter continuous 
parametric monitoring system (PM CPMS) according to the requirements 
specified in subpart UUUUU of part 63.

Sec. 60.46  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, and 
subsequent performance tests as requested by the EPA Administrator, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b). 
Acceptable alternative methods and procedures are given in paragraph (d) 
of this section.
    (b) The owner or operator shall determine compliance with the PM, 
SO2, and NOX standards in Sec. Sec. 60.42, 60.43, 
and 60.44 as follows:
    (1) The emission rate (E) of PM, SO2, or NOX 
shall be computed for each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TR13JN07.006

Where:

E = Emission rate of pollutant, ng/J (1b/million Btu);
C = Concentration of pollutant, ng/dscm (1b/dscf);
%O2 = O2 concentration, percent dry basis; and
Fd = Factor as determined from Method 19 of appendix A of 
          this part.

    (2) Method 5 of appendix A of this part shall be used to determine 
the PM concentration (C) at affected facilities without wet flue-gas-
desulfurization (FGD) systems and Method 5B of appendix A of this part 
shall be used to determine the PM concentration (C) after FGD systems.
    (i) The sampling time and sample volume for each run shall be at 
least 60 minutes and 0.85 dscm (30 dscf). The probe and filter holder 
heating systems in the sampling train shall be set to provide an average 
gas temperature of 16014 [deg]C (32025 [deg]F).
    (ii) The emission rate correction factor, integrated or grab 
sampling and analysis procedure of Method 3B of appendix A of this part 
shall be used to determine the O2 concentration 
(%O2). The O2 sample shall be obtained 
simultaneously with, and at the same traverse points as, the particulate 
sample. If the grab sampling procedure is used, the O2 
concentration for the run shall be the arithmetic mean of the sample 
O2 concentrations at all traverse points.
    (iii) If the particulate run has more than 12 traverse points, the 
O2 traverse points may be reduced to 12 provided that Method 
1 of appendix A of this part is used to locate the 12 O2 
traverse points.
    (3) Method 9 of appendix A of this part and the procedures in Sec. 
60.11 shall be used to determine opacity.
    (4) Method 6 of appendix A of this part shall be used to determine 
the SO2 concentration.
    (i) The sampling site shall be the same as that selected for the 
particulate sample. The sampling location in the duct shall be at the 
centroid of the cross section or at a point no closer to the walls than 
1 m (3.28 ft). The sampling time and sample volume for each sample run 
shall be at least 20 minutes and 0.020 dscm (0.71 dscf). Two samples 
shall be taken during a 1-hour period, with each sample taken within a 
30-minute interval.
    (ii) The emission rate correction factor, integrated sampling and 
analysis procedure of Method 3B of appendix A of this part shall be used 
to determine the O2 concentration (%O2). The 
O2 sample shall be taken simultaneously with, and at the same 
point as, the SO2 sample. The SO2 emission rate 
shall be computed for each pair of SO2 and O2 
samples. The SO2 emission rate (E) for each run shall be the 
arithmetic mean of the results of the two pairs of samples.
    (5) Method 7 of appendix A of this part shall be used to determine 
the NOX concentration.
    (i) The sampling site and location shall be the same as for the 
SO2 sample. Each run shall consist of four grab samples, with 
each sample taken at about 15-minute intervals.
    (ii) For each NOX sample, the emission rate correction 
factor, grab sampling and analysis procedure of Method 3B of appendix A 
of this part shall be

[[Page 170]]

used to determine the O2 concentration (%O2). The 
sample shall be taken simultaneously with, and at the same point as, the 
NOX sample.
    (iii) The NOX emission rate shall be computed for each 
pair of NOX and O2 samples. The NOX 
emission rate (E) for each run shall be the arithmetic mean of the 
results of the four pairs of samples.
    (c) When combinations of fossil fuels or fossil fuel and wood 
residue are fired, the owner or operator (in order to compute the 
prorated standard as shown in Sec. Sec. 60.43(b) and 60.44(b)) shall 
determine the percentage (w, x, y, or z) of the total heat input derived 
from each type of fuel as follows:
    (1) The heat input rate of each fuel shall be determined by 
multiplying the gross calorific value of each fuel fired by the rate of 
each fuel burned.
    (2) ASTM Methods D2015, or D5865 (solid fuels), D240 (liquid fuels), 
or D1826 (gaseous fuels) (all of these methods are incorporated by 
reference, see Sec. 60.17) shall be used to determine the gross 
calorific values of the fuels. The method used to determine the 
calorific value of wood residue must be approved by the Administrator.
    (3) Suitable methods shall be used to determine the rate of each 
fuel burned during each test period, and a material balance over the 
steam generating system shall be used to confirm the rate.
    (d) The owner or operator may use the following as alternatives to 
the reference methods and procedures in this section or in other 
sections as specified:
    (1) The emission rate (E) of PM, SO2 and NOX 
may be determined by using the Fc factor, provided that the following 
procedure is used:
    (i) The emission rate (E) shall be computed using the following 
equation:

[GRAPHIC] [TIFF OMITTED] TR13JN07.007

Where:

E = Emission rate of pollutant, ng/J (lb/MMBtu);
C = Concentration of pollutant, ng/dscm (lb/dscf);
%CO2 = CO2 concentration, percent dry basis; and
Fc = Factor as determined in appropriate sections of Method 
          19 of appendix A of this part.

    (ii) If and only if the average Fc factor in Method 19 of appendix A 
of this part is used to calculate E and either E is from 0.97 to 1.00 of 
the emission standard or the relative accuracy of a continuous emission 
monitoring system is from 17 to 20 percent, then three runs of Method 3B 
of appendix A of this part shall be used to determine the O2 
and CO2 concentration according to the procedures in 
paragraph (b)(2)(ii), (4)(ii), or (5)(ii) of this section. Then if 
Fo (average of three runs), as calculated from the equation 
in Method 3B of appendix A of this part, is more than 3 percent than the average Fo value, as 
determined from the average values of Fd and Fc in 
Method 19 of appendix A of this part, i.e., Foa = 0.209 
(Fda/Fca), then the following procedure shall be 
followed:
    (A) When Fo is less than 0.97 Foa, then E 
shall be increased by that proportion under 0.97 Foa, e.g., 
if Fo is 0.95 Foa, E shall be increased by 2 
percent. This recalculated value shall be used to determine compliance 
with the emission standard.
    (B) When Fo is less than 0.97 Foa and when the 
average difference (d) between the continuous monitor minus the 
reference methods is negative, then E shall be increased by that 
proportion under 0.97 Foa, e.g., if Fo is 0.95 
Foa, E shall be increased by 2 percent. This recalculated 
value shall be used to determine compliance with the relative accuracy 
specification.
    (C) When Fo is greater than 1.03 Foa and when 
the average difference d is positive, then E shall be decreased by that 
proportion over 1.03 Foa, e.g., if Fo is 1.05 
Foa, E shall be decreased by 2 percent. This recalculated 
value shall be used to determine compliance with the relative accuracy 
specification.
    (2) For Method 5 or 5B of appendix A-3 of this part, Method 17 of 
appendix A-6 of this part may be used at facilities with or without wet 
FGD systems if the stack gas temperature at the sampling location does 
not exceed an average temperature of 160 [deg]C (320 [deg]F). The 
procedures of sections 8.1 and 11.1 of Method 5B of appendix A-3 of this 
part

[[Page 171]]

may be used with Method 17 of appendix A-6 of this part only if it is 
used after wet FGD systems. Method 17 of appendix A-6 of this part shall 
not be used after wet FGD systems if the effluent gas is saturated or 
laden with water droplets.
    (3) Particulate matter and SO2 may be determined 
simultaneously with the Method 5 of appendix A of this part train 
provided that the following changes are made:
    (i) The filter and impinger apparatus in sections 2.1.5 and 2.1.6 of 
Method 8 of appendix A of this part is used in place of the condenser 
(section 2.1.7) of Method 5 of appendix A of this part.
    (ii) All applicable procedures in Method 8 of appendix A of this 
part for the determination of SO2 (including moisture) are 
used:
    (4) For Method 6 of appendix A of this part, Method 6C of appendix A 
of this part may be used. Method 6A of appendix A of this part may also 
be used whenever Methods 6 and 3B of appendix A of this part data are 
specified to determine the SO2 emission rate, under the 
conditions in paragraph (d)(1) of this section.
    (5) For Method 7 of appendix A of this part, Method 7A, 7C, 7D, or 
7E of appendix A of this part may be used. If Method 7C, 7D, or 7E of 
appendix A of this part is used, the sampling time for each run shall be 
at least 1 hour and the integrated sampling approach shall be used to 
determine the O2 concentration (%O2) for the 
emission rate correction factor.
    (6) For Method 3 of appendix A of this part, Method 3A or 3B of 
appendix A of this part may be used.
    (7) For Method 3B of appendix A of this part, Method 3A of appendix 
A of this part may be used.

Sec. 60.48Da  Compliance provisions.

    (a) For affected facilities for which construction, modification, or 
reconstruction commenced before May 4, 2011, the applicable PM emissions 
limit and opacity standard under Sec. 60.42Da, SO2 emissions 
limit under Sec. 60.43Da, and NOX emissions limit under 
Sec. 60.44Da apply at all times except during periods of startup, 
shutdown, or malfunction. For affected facilities for which 
construction, modification, or reconstruction commenced after May 3, 
2011, the applicable SO2 emissions limit under Sec. 60.43Da, 
NOX emissions limit

[[Page 184]]

under Sec. 60.44Da, and NOX plus CO emissions limit under 
Sec. 60.45Da apply at all times. The applicable PM emissions limit and 
opacity standard under Sec. 60.42Da apply at all times except during 
periods of startup and shutdown.
    (b) After the initial performance test required under Sec. 60.8, 
compliance with the applicable SO2 emissions limit and 
percentage reduction requirements under Sec. 60.43Da, NOX 
emissions limit under Sec. 60.44Da, and NOX plus CO 
emissions limit under Sec. 60.45Da is based on the average emission 
rate for 30 successive boiler operating days. A separate performance 
test is completed at the end of each boiler operating day after the 
initial performance test, and a new 30-boiler operating day rolling 
average emission rate for both SO2, NOX or 
NOX plus CO as applicable, and a new percent reduction for 
SO2 are calculated to demonstrate compliance with the 
standards.
    (c) For the initial performance test required under Sec. 60.8, 
compliance with the applicable SO2 emissions limits and 
percentage reduction requirements under Sec. 60.43Da, the 
NOX emissions limits under Sec. 60.44Da, and the 
NOX plus CO emissions limits under Sec. 60.45Da is based on 
the average emission rates for SO2, NOX, CO, and 
percent reduction for SO2 for the first 30 successive boiler 
operating days. The initial performance test is the only test in which 
at least 30 days prior notice is required unless otherwise specified by 
the Administrator. The initial performance test is to be scheduled so 
that the first boiler operating day of the 30 successive boiler 
operating days is completed within 60 days after achieving the maximum 
production rate at which the affected facility will be operated, but not 
later than 180 days after initial startup of the facility.
    (d) For affected facilities for which construction, modification, or 
reconstruction commenced before May 4, 2011, compliance with applicable 
30-boiler operating day rolling average SO2 and 
NOX emissions limits is determined by calculating the 
arithmetic average of all hourly emission rates for SO2 and 
NOX for the 30 successive boiler operating days, except for 
data obtained during startup, shutdown, or malfunction. For affected 
facilities for which construction, modification, or reconstruction 
commenced after May 3, 2011, compliance with applicable 30-boiler 
operating day rolling average SO2 and NOX 
emissions limits is determined by dividing the sum of the SO2 
and NOX emissions for the 30 successive boiler operating days 
by the sum of the gross energy output or net energy output, as 
applicable, for the 30 successive boiler operating days.
    (e) For affected facilities for which construction, modification, or 
reconstruction commenced before May 4, 2011, compliance with applicable 
SO2 percentage reduction requirements is determined based on 
the average inlet and outlet SO2 emission rates for the 30 
successive boiler operating days. For affected facilities for which 
construction, modification, or reconstruction commenced after May 3, 
2011, compliance with applicable SO2 percentage reduction 
requirements is determined based on the ``as fired'' total potential 
emissions and the total outlet SO2 emissions for the 30 
successive boiler operating days.
    (f) For affected facilities for which construction, modification, or 
reconstruction commenced before May 4, 2011, compliance with the 
applicable daily average PM emissions limit is determined by calculating 
the arithmetic average of all hourly emission rates each boiler 
operating day, except for data obtained during startup, shutdown, or 
malfunction periods. Daily averages are only calculated for boiler 
operating days that have non-out-of-control data for at least 18 hours 
of unit operation during which the standard applies. Instead, all of the 
non-out-of-control hourly emission rates of the operating day(s) not 
meeting the minimum 18 hours non-out-of-control data daily average 
requirement are averaged with all of the non-out-of-control hourly 
emission rates of the next boiler operating day with 18 hours or more of 
non-out-of-control PM CEMS data to determine compliance. For affected 
facilities for which construction or reconstruction commenced after May 
3, 2011 that elect to demonstrate compliance using PM CEMS, compliance 
with the applicable PM emissions limit in Sec. 60.42Da is determined on 
a 30-boiler operating day rolling average basis by

[[Page 185]]

calculating the arithmetic average of all hourly PM emission rates for 
the 30 successive boiler operating days, except for data obtained during 
periods of startup and shutdown.
    (g) For affected facilities for which construction, modification, or 
reconstruction commenced after May 3, 2011, compliance with applicable 
30-boiler operating day rolling average NOX plus CO emissions 
limit is determined by dividing the sum of the NOX plus CO 
emissions for the 30 successive boiler operating days by the sum of the 
gross energy output or net energy output, as applicable, for the 30 
successive boiler operating days.
    (h) If an owner or operator has not obtained the minimum quantity of 
emission data as required under Sec. 60.49Da of this subpart, 
compliance of the affected facility with the emission requirements under 
Sec. Sec. 60.43Da and 60.44Da of this subpart for the day on which the 
30-day period ends may be determined by the Administrator by following 
the applicable procedures in section 7 of Method 19 of appendix A of 
this part.
    (i) Compliance provisions for sources subject to Sec. 
60.44Da(d)(1), (e)(1), (e)(2)(i), (e)(3)(i), (f), or (g). The owner or 
operator shall calculate NOX emissions as 1.194 x 
10-7 lb/scf-ppm times the average hourly NOX 
output concentration in ppm (measured according to the provisions of 
Sec. 60.49Da(c)), times the average hourly flow rate (measured in scfh, 
according to the provisions of Sec. 60.49Da(l) or Sec. 60.49Da(m)), 
divided by the average hourly gross energy output (measured according to 
the provisions of Sec. 60.49Da(k)) or the average hourly net energy 
output, as applicable. Alternatively, for oil-fired and gas-fired units, 
NOX emissions may be calculated by multiplying the hourly 
NOX emission rate in lb/MMBtu (measured by the CEMS required 
under Sec. 60.49Da(c) and (d)), by the hourly heat input rate (measured 
according to the provisions of Sec. 60.49Da(n)), and dividing the 
result by the average gross energy output (measured according to the 
provisions of Sec. 60.49Da(k)) or the average hourly net energy output, 
as applicable.
    (j) Compliance provisions for duct burners subject to Sec. 
60.44Da(a)(1). To determine compliance with the emissions limits for 
NOX required by Sec. 60.44Da(a) for duct burners used in 
combined cycle systems, either of the procedures described in paragraph 
(j)(1) or (2) of this section may be used:
    (1) The owner or operator of an affected duct burner shall conduct 
the performance test required under Sec. 60.8 using the appropriate 
methods in appendix A of this part. Compliance with the emissions limits 
under Sec. 60.44Da(a)(1) is determined on the average of three (nominal 
1-hour) runs for the initial and subsequent performance tests. During 
the performance test, one sampling site shall be located in the exhaust 
of the turbine prior to the duct burner. A second sampling site shall be 
located at the outlet from the heat recovery steam generating unit. 
Measurements shall be taken at both sampling sites during the 
performance test; or
    (2) The owner or operator of an affected duct burner may elect to 
determine compliance by using the CEMS specified under Sec. 60.49Da for 
measuring NOX and oxygen (O2) (or carbon dioxide 
(CO2)) and meet the requirements of Sec. 60.49Da. 
Alternatively, data from a NOX emission rate (i.e., 
NOX-diluent) CEMS certified according to the provisions of 
Sec. 75.20(c) of this chapter and appendix A to part 75 of this 
chapter, and meeting the quality assurance requirements of Sec. 75.21 
of this chapter and appendix B to part 75 of this chapter, may be used, 
with the following caveats. Data used to meet the requirements of Sec. 
60.51Da shall not include substitute data values derived from the 
missing data procedures in subpart D of part 75 of this chapter, nor 
shall the data have been bias adjusted according to the procedures of 
part 75 of this chapter. The sampling site shall be located at the 
outlet from the steam generating unit. The NOX emission rate 
at the outlet from the steam generating unit shall constitute the 
NOX emission rate from the duct burner of the combined cycle 
system.
    (k) Compliance provisions for duct burners subject to Sec. 
60.44Da(d)(1) or (e)(1). To determine compliance with the emission 
limitation for NOX required by Sec. 60.44Da(d)(1) or (e)(1) 
for duct burners used in combined cycle systems, either of the 
procedures described in

[[Page 186]]

paragraphs (k)(1) and (2) of this section may be used:

NOX emission limitation in Sec. 60.44Da(d)(1) or (e)(1) as 
follows:
    (i) The emission rate (E) of NOX shall be computed using 
Equation 2 in this section:
[GRAPHIC] [TIFF OMITTED] TR16FE12.000

Where:

E = Emission rate of NOX from the duct burner, ng/J (lb/MWh) 
          gross energy output;

          affected duct burner.

    (ii) Method 7E of appendix A of this part shall be used to determine 
the NOX concentrations (Csg and Cte). 
Method 2, 2F or 2G of appendix A of this part, as appropriate, shall be 
used to determine the volumetric flow rates (Qsg and 
Qte) of the exhaust gases. The volumetric flow rate 
measurements shall be taken at the same time as the concentration 
measurements.
    (iii) The owner or operator shall develop, demonstrate, and provide 
information satisfactory to the Administrator to determine the average 
hourly gross energy output from the steam generating unit, and the 
average hourly percentage of the total heat input to the steam 
generating unit derived from the combustion of fuel in the affected duct 
burner.
    (iv) Compliance with the applicable NOX emission 
limitation in Sec. 60.44Da(d)(1) or (e)(1) is determined by the three-
run average (nominal 1-hour runs) for the initial and subsequent 
performance tests.
    (2) The owner or operator of an affected duct burner used in a 
combined cycle system may elect to determine compliance with the 
applicable NOX emission limitation in Sec. 60.44Da(d)(1) or 
(e)(1) on a 30-day rolling average basis as indicated in paragraphs 
(k)(2)(i) through (iv) of this section.

          gross energy output;
Csg = Average hourly concentration of NOX exiting 
          the steam generating unit, ng/dscm (lb/dscf);
Qsg = Average hourly volumetric flow rate of exhaust gas from 
          steam generating unit, dscm/h (dscf/h); and
Occ = Average hourly gross energy output from entire combined 
          cycle unit, J/h (MW).

    (ii) The CEMS specified under Sec. 60.49Da for measuring 
NOX and O2 (or

[[Page 187]]

CO2) shall be used to determine the average hourly 
NOX concentrations (Csg). The continuous flow 
monitoring system specified in Sec. 60.49Da(l) or Sec. 60.49Da(m) 
shall be used to determine the volumetric flow rate (Qsg) of 
the exhaust gas. If the option to use the flow monitoring system in 
Sec. 60.49Da(m) is selected, the flow rate data used to meet the 
requirements of Sec. 60.51Da shall not include substitute data values 
derived from the missing data procedures in subpart D of part 75 of this 
chapter, nor shall the data have been bias adjusted according to the 
procedures of part 75 of this chapter. The sampling site shall be 
located at the outlet from the steam generating unit.
    (iii) The continuous monitoring system specified under Sec. 
60.49Da(k) for measuring and determining gross energy output shall be 
used to determine the average hourly gross energy output from the entire 
combined cycle unit (Occ), which is the combined output from 
the combustion turbine and the steam generating unit.
    (iv) The owner or operator may, in lieu of installing, operating, 
and recording data from the continuous flow monitoring system specified 
in Sec. 60.49Da(l), determine the mass rate (lb/h) of NOX 
emissions by installing, operating, and maintaining continuous fuel 
flowmeters following the appropriate measurements procedures specified 
in appendix D of part 75 of this chapter. If this compliance option is 
selected, the emission rate (E) of NOX shall be computed 
using Equation 4 in this section:
[GRAPHIC] [TIFF OMITTED] TR16FE12.002

Where:

E = Emission rate of NOX from the duct burner, ng/J (lb/MWh) 
          gross energy output;
ERsg = Average hourly emission rate of NOX exiting 
          the steam generating unit heat input calculated using

          unit, J/h (MMBtu/h); and
Occ = Average hourly gross energy output from entire combined 
          cycle unit, J/h (MW).

    (3) When an affected duct burner steam generating unit utilizes a 
common steam turbine with one or more affected duct burner steam 
generating units, the owner or operator shall either:
    (i) Determine compliance with the applicable NOX 
emissions limits by measuring the emissions combined with the emissions 
from the other unit(s) utilizing the common steam turbine; or
    (ii) Develop, demonstrate, and provide information satisfactory to 
the Administrator on methods for apportioning the combined gross energy 
output from the steam turbine for each of the affected duct burners. The 
Administrator may approve such demonstrated substitute methods for 
apportioning the combined gross energy output measured at the steam 
turbine whenever the demonstration ensures accurate estimation of 
emissions regulated under this part.
    (l) [Reserved]
    (m) Compliance provisions for sources subject to Sec. 
60.43Da(i)(1)(i), (i)(2)(i), (i)(3)(i), (j)(1)(i), (j)(2)(i), (j)(3)(i), 
(l)(1)(i), (l)(1)(ii), or (l)(2). The owner or operator shall calculate 
SO2 emissions as 1.660 x 10-7 lb/scf-ppm times the 
average hourly SO2 output concentration in ppm (measured 
according to the provisions of Sec. 60.49Da(b)), times the average 
hourly flow rate (measured according to the provisions of Sec. 
60.49Da(l) or Sec. 60.49Da(m)), divided by the average hourly gross 
energy output (measured according to the provisions of Sec. 60.49Da(k)) 
or the average hourly net energy output, as applicable. Alternatively, 
for oil-fired and gas-fired units, SO2 emissions may be 
calculated by multiplying the hourly SO2 emission rate (in 
lb/MMBtu), measured by the CEMS required under Sec. 60.49Da, by

[[Page 188]]

the hourly heat input rate (measured according to the provisions of 
Sec. 60.49Da(n)), and dividing the result by the average gross energy 
output (measured according to the provisions of Sec. 60.49Da(k)) or the 
average hourly net energy output, as applicable.
    (n) Compliance provisions for sources subject to Sec. 60.42Da(c)(1) 
or (e)(1)(i). The owner or operator shall calculate PM emissions by 
multiplying the average hourly PM output concentration (measured 
according to the provisions of Sec. 60.49Da(t)), by the average hourly 
flow rate (measured according to the provisions of Sec. 60.49Da(l) or 
Sec. 60.49Da(m)), and dividing by the average hourly gross energy 
output (measured according to the provisions of Sec. 60.49Da(k)) or the 
average hourly net energy output, as applicable.
    (o) Compliance provisions for sources subject to Sec. 
60.42Da(c)(2), (d), or (e)(1)(ii). Except as provided for in paragraph 
(p) of this section, the owner or operator must demonstrate compliance 
with each applicable emissions limit according to the requirements in 
paragraphs (o)(1) through (o)(5) of this section.
    (1) You must conduct a performance test to demonstrate initial 
compliance with the applicable PM emissions limit in Sec. 60.42Da by 
the applicable date specified in Sec. 60.8(a). Thereafter, you must 
conduct each subsequent performance test within 12 calendar months 
following the date the previous performance test was required to be 
conducted. You must conduct each performance test according to the 
requirements in Sec. 60.8 using the test methods and procedures in 
Sec. 60.50Da. The owner or operator of an affected facility that has 
not operated for 60 consecutive calendar days prior to the date that the 
subsequent performance test would have been required had the unit been 
operating is not required to perform the subsequent performance test 
until 30 calendar days after the next boiler operating day. Requests for 
additional 30 day extensions shall be granted by the relevant air 
division or office director of the appropriate Regional Office of the 
U.S. EPA.
    (2) You must monitor the performance of each electrostatic 
precipitator or fabric filter (baghouse) operated to comply with the 
applicable PM emissions limit in Sec. 60.42Da using a continuous 
opacity monitoring system (COMS) according to the requirements in 
paragraphs (o)(2)(i) through (vi) unless you elect to comply with one of 
the alternatives provided in paragraphs (o)(3) and (o)(4) of this 
section, as applicable to your control device.
    (i) Each COMS must meet Performance Specification 1 in 40 CFR part 
60, appendix B.
    (ii) You must comply with the quality assurance requirements in 
paragraphs (o)(2)(ii)(A) through (E) of this section.
    (A) You must automatically (intrinsic to the opacity monitor) check 
the zero and upscale (span) calibration drifts at least once daily. For 
a particular COMS, the acceptable range of zero and upscale calibration 
materials is as defined in the applicable version of Performance 
Specification 1 in 40 CFR part 60, appendix B.
    (B) You must adjust the zero and span whenever the 24-hour zero 
drift or 24-hour span drift exceeds 4 percent opacity. The COMS must 
allow for the amount of excess zero and span drift measured at the 24-
hour interval checks to be recorded and quantified. The optical surfaces 
exposed to the effluent gases must be cleaned prior to performing the 
zero and span drift adjustments, except for systems using automatic zero 
adjustments. For systems using automatic zero adjustments, the optical 
surfaces must be cleaned when the cumulative automatic zero compensation 
exceeds 4 percent opacity.
    (C) You must apply a method for producing a simulated zero opacity 
condition and an upscale (span) opacity condition using a certified 
neutral density filter or other related technique to produce a known 
obscuration of the light beam. All procedures applied must provide a 
system check of the analyzer internal optical surfaces and all 
electronic circuitry including the lamp and photodetector assembly.
    (D) Except during periods of system breakdowns, repairs, calibration 
checks, and zero and span adjustments, the COMS must be in continuous 
operation and must complete a minimum of one cycle of sampling and 
analyzing for

[[Page 189]]

each successive 10 second period and one cycle of data recording for 
each successive 6-minute period.
    (E) You must reduce all data from the COMS to 6-minute averages. 
Six-minute opacity averages must be calculated from 36 or more data 
points equally spaced over each 6-minute period. Data recorded during 
periods of system breakdowns, repairs, calibration checks, and zero and 
span adjustments must not be included in the data averages. An 
arithmetic or integrated average of all data may be used.
    (iii) During each performance test conducted according to paragraph 
(o)(1) of this section, you must establish an opacity baseline level. 
The value of the opacity baseline level is determined by averaging all 
of the 6-minute average opacity values (reported to the nearest 0.1 
percent opacity) from the COMS measurements recorded during each of the 
test run intervals conducted for the performance test, and then adding 
2.5 percent opacity to your calculated average opacity value for all of 
the test runs. If your opacity baseline level is less than 5.0 percent, 
then the opacity baseline level is set at 5.0 percent.
    (iv) You must evaluate the preceding 24-hour average opacity level 
measured by the COMS each boiler operating day excluding periods of 
affected facility startup, shutdown, or malfunction. If the measured 24-
hour average opacity emission level is greater than the baseline opacity 
level determined in paragraph (o)(2)(iii) of this section, you must 
initiate investigation of the relevant equipment and control systems 
within 24 hours of the first discovery of the high opacity incident and 
take the appropriate corrective action as soon as practicable to adjust 
control settings or repair equipment to reduce the measured 24-hour 
average opacity to a level below the baseline opacity level. In cases 
when a wet scrubber is used in combination with another PM control 
device that serves as the primary PM control device, the wet scrubber 
must be maintained and operated.
    (v) You must record the opacity measurements, calculations 
performed, and any corrective actions taken. The record of corrective 
action taken must include the date and time during which the measured 
24-hour average opacity was greater than baseline opacity level, and the 
date, time, and description of the corrective action.
    (vi) If the measured 24-hour average opacity for your affected 
facility remains at a level greater than the opacity baseline level 
after 7 boiler operating days, then you must conduct a new PM 
performance test according to paragraph (o)(1) of this section and 
establish a new opacity baseline value according to paragraph (o)(2) of 
this section. This new performance test must be conducted within 60 days 
of the date that the measured 24-hour average opacity was first 
determined to exceed the baseline opacity level unless a waiver is 
granted by the permitting authority.
    (3) As an alternative to complying with the requirements of 
paragraph (o)(2) of this section, an owner or operator may elect to 
monitor the performance of an electrostatic precipitator (ESP) operated 
to comply with the applicable PM emissions limit in Sec. 60.42Da using 
an ESP predictive model developed in accordance with the requirements in 
paragraphs (o)(3)(i) through (v) of this section.
    (i) You must calibrate the ESP predictive model with each PM control 
device used to comply with the applicable PM emissions limit in Sec. 
60.42Da operating under normal conditions. In cases when a wet scrubber 
is used in combination with an ESP to comply with the PM emissions 
limit, the wet scrubber must be maintained and operated.
    (ii) You must develop a site-specific monitoring plan that includes 
a description of the ESP predictive model used, the model input 
parameters, and the procedures and criteria for establishing monitoring 
parameter baseline levels indicative of compliance with the PM emissions 
limit. You must submit the site-specific monitoring plan for approval by 
the permitting authority. For reference purposes in preparing the 
monitoring plan, see the OAQPS ``Compliance Assurance Monitoring (CAM) 
Protocol for an Electrostatic Precipitator (ESP) Controlling Particulate 
Matter (PM) Emissions from a Coal-Fired Boiler.'' This document is 
available from the U.S. Environmental Protection Agency (U.S.

[[Page 190]]

EPA); Office of Air Quality Planning and Standards; Sector Policies and 
Programs Division; Measurement Policy Group (D243-02), Research Triangle 
Park, NC 27711. This document is also available on the Technology 
Transfer Network (TTN) under Emission Measurement Center Continuous 
Emission Monitoring.
    (iii) You must run the ESP predictive model using the applicable 
input data each boiler operating day and evaluate the model output for 
the preceding boiler operating day excluding periods of affected 
facility startup, shutdown, or malfunction. If the values for one or 
more of the model parameters exceed the applicable baseline levels 
determined according to your approved site-specific monitoring plan, you 
must initiate investigation of the relevant equipment and control 
systems within 24 hours of the first discovery of a model parameter 
deviation and, take the appropriate corrective action as soon as 
practicable to adjust control settings or repair equipment to return the 
model output to within the applicable baseline levels.
    (iv) You must record the ESP predictive model inputs and outputs and 
any corrective actions taken. The record of corrective action taken must 
include the date and time during which the model output values exceeded 
the applicable baseline levels, and the date, time, and description of 
the corrective action.
    (v) If after 7 consecutive days a model parameter continues to 
exceed the applicable baseline level, then you must conduct a new PM 
performance test according to paragraph (o)(1) of this section. This new 
performance test must be conducted within 60 calendar days of the date 
that the model parameter was first determined to exceed its baseline 
level unless a waiver is granted by the permitting authority.
    (4) As an alternative to complying with the requirements of 
paragraph (o)(2) of this section, an owner or operator may elect to 
monitor the performance of a fabric filter (baghouse) operated to comply 
with the applicable PM emissions limit in Sec. 60.42Da by using a bag 
leak detection system according to the requirements in paragraphs 
(o)(4)(i) through (v) of this section.
    (i) Each bag leak detection system must meet the specifications and 
requirements in paragraphs (o)(4)(i)(A) through (H) of this section.
    (A) The bag leak detection system must be certified by the 
manufacturer to be capable of detecting PM emissions at concentrations 
of 1 milligram per actual cubic meter (0.00044 grains per actual cubic 
foot) or less.
    (B) The bag leak detection system sensor must provide output of 
relative PM loadings. The owner or operator must continuously record the 
output from the bag leak detection system using electronic or other 
means (e.g., using a strip chart recorder or a data logger.)
    (C) The bag leak detection system must be equipped with an alarm 
system that will react when the system detects an increase in relative 
particulate loading over the alarm set point established according to 
paragraph (o)(4)(i)(D) of this section, and the alarm must be located 
such that it can be noticed by the appropriate plant personnel.
    (D) In the initial adjustment of the bag leak detection system, you 
must establish, at a minimum, the baseline output by adjusting the 
sensitivity (range) and the averaging period of the device, the alarm 
set points, and the alarm delay time.
    (E) Following initial adjustment, you must not adjust the averaging 
period, alarm set point, or alarm delay time without approval from the 
permitting authority except as provided in paragraph (d)(1)(vi) of this 
section.
    (F) Once per quarter, you may adjust the sensitivity of the bag leak 
detection system to account for seasonal effects, including temperature 
and humidity, according to the procedures identified in the site-
specific monitoring plan required by paragraph (o)(4)(ii) of this 
section.
    (G) You must install the bag leak detection sensor downstream of the 
fabric filter and upstream of any wet scrubber.
    (H) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (ii) You must develop and submit to the permitting authority for 
approval a

[[Page 191]]

site-specific monitoring plan for each bag leak detection system. You 
must operate and maintain the bag leak detection system according to the 
site-specific monitoring plan at all times. Each monitoring plan must 
describe the items in paragraphs (o)(4)(ii)(A) through (F) of this 
section.
    (A) Installation of the bag leak detection system;
    (B) Initial and periodic adjustment of the bag leak detection 
system, including how the alarm set-point will be established;
    (C) Operation of the bag leak detection system, including quality 
assurance procedures;
    (D) How the bag leak detection system will be maintained, including 
a routine maintenance schedule and spare parts inventory list;
    (E) How the bag leak detection system output will be recorded and 
stored; and
    (F) Corrective action procedures as specified in paragraph 
(o)(4)(iii) of this section. In approving the site-specific monitoring 
plan, the permitting authority may allow owners and operators more than 
3 hours to alleviate a specific condition that causes an alarm if the 
owner or operator identifies in the monitoring plan this specific 
condition as one that could lead to an alarm, adequately explains why it 
is not feasible to alleviate this condition within 3 hours of the time 
the alarm occurs, and demonstrates that the requested time will ensure 
alleviation of this condition as expeditiously as practicable.
    (iii) For each bag leak detection system, you must initiate 
procedures to determine the cause of every alarm within 1 hour of the 
alarm. Except as provided in paragraph (o)(4)(ii)(F) of this section, 
you must alleviate the cause of the alarm within 3 hours of the alarm by 
taking whatever corrective action(s) are necessary. Corrective actions 
may include, but are not limited to the following:
    (A) Inspecting the fabric filter for air leaks, torn or broken bags 
or filter media, or any other condition that may cause an increase in 
particulate emissions;
    (B) Sealing off defective bags or filter media;
    (C) Replacing defective bags or filter media or otherwise repairing 
the control device;
    (D) Sealing off a defective fabric filter compartment;
    (E) Cleaning the bag leak detection system probe or otherwise 
repairing the bag leak detection system; or
    (F) Shutting down the process producing the particulate emissions.
    (iv) You must maintain records of the information specified in 
paragraphs (o)(4)(iv)(A) through (C) of this section for each bag leak 
detection system.
    (A) Records of the bag leak detection system output;
    (B) Records of bag leak detection system adjustments, including the 
date and time of the adjustment, the initial bag leak detection system 
settings, and the final bag leak detection system settings; and
    (C) The date and time of all bag leak detection system alarms, the 
time that procedures to determine the cause of the alarm were initiated, 
if procedures were initiated within 1 hour of the alarm, the cause of 
the alarm, an explanation of the actions taken, the date and time the 
cause of the alarm was alleviated, and if the alarm was alleviated 
within 3 hours of the alarm.
    (v) If after any period composed of 30 boiler operating days during 
which the alarm rate exceeds 5 percent of the process operating time 
(excluding control device or process startup, shutdown, and 
malfunction), then you must conduct a new PM performance test according 
to paragraph (o)(1) of this section. This new performance test must be 
conducted within 60 calendar days of the date that the alarm rate was 
first determined to exceed 5 percent limit unless a waiver is granted by 
the permitting authority.
    (5) An owner or operator of a modified affected facility electing to 
meet the emission limitations in Sec. 60.42Da(d) shall determine the 
percent reduction in PM by using the emission rate for PM determined by 
the performance test conducted according to the requirements in 
paragraph (o)(1) of this section and the ash content on a mass basis of 
the fuel burned during each performance test run as determined by 
analysis of the fuel as fired.

[[Page 192]]

    (p) As an alternative to meeting the compliance provisions specified 
in paragraph (o) of this section, an owner or operator may elect to 
install, evaluate, maintain, and operate a CEMS measuring PM emissions 
discharged from the affected facility to the atmosphere and record the 
output of the system as specified in paragraphs (p)(1) through (p)(8) of 
this section.
    (1) The owner or operator shall submit a written notification to the 
Administrator of intent to demonstrate compliance with this subpart by 
using a CEMS measuring PM. This notification shall be sent at least 30 
calendar days before the initial startup of the monitor for compliance 
determination purposes. The owner or operator may discontinue operation 
of the monitor and instead return to demonstration of compliance with 
this subpart according to the requirements in paragraph (o) of this 
section by submitting written notification to the Administrator of such 
intent at least 30 calendar days before shutdown of the monitor for 
compliance determination purposes.
    (2) Each CEMS shall be installed, evaluated, operated, and 
maintained according to the requirements in Sec. 60.49Da(v).
    (3) The initial performance evaluation shall be completed no later 
than 180 days after the date of initial startup of the affected 
facility, as specified under Sec. 60.8 of subpart A of this part or 
within 180 days of the date of notification to the Administrator 
required under paragraph (p)(1) of this section, whichever is later.
    (4) Compliance with the applicable emissions limit shall be 
determined based on the 24-hour daily (block) average of the hourly 
arithmetic average emissions concentrations using the continuous 
monitoring system outlet data. The 24-hour block arithmetic average 
emission concentration shall be calculated using EPA Reference Method 19 
of appendix A of this part, section 4.1.
    (5) At a minimum, non-out-of-control CEMS hourly averages shall be 
obtained for 75 percent of all operating hours on a 30-boiler operating 
day rolling average basis. Beginning on January 1, 2012, non-out-of-
control CEMS hourly averages shall be obtained for 90 percent of all 
operating hours on a 30-boiler operating day rolling average basis.
    (i) At least two data points per hour shall be used to calculate 
each 1-hour arithmetic average.
    (ii) [Reserved]
    (6) The 1-hour arithmetic averages required shall be expressed in 
ng/J, MMBtu/hr, or lb/MWh and shall be used to calculate the boiler 
operating day daily arithmetic average emission concentrations. The 1-
hour arithmetic averages shall be calculated using the data points 
required under Sec. 60.13(e)(2) of subpart A of this part.
    (7) All non-out-of-control CEMS data shall be used in calculating 
average emission concentrations even if the minimum CEMS data 
requirements of paragraph (j)(5) of this section are not met.
    (8) When PM emissions data are not obtained because of CEMS 
breakdowns, repairs, calibration checks, and zero and span adjustments, 
emissions data shall be obtained by using other monitoring systems as 
approved by the Administrator or EPA Reference Method 19 of appendix A 
of this part to provide, as necessary, non-out-of-control emissions data 
for a minimum of 90 percent (only 75 percent is required prior to 
January 1, 2012) of all operating hours per 30-boiler operating day 
rolling average.
    (q) Compliance provisions for sources subject to Sec. 60.42Da(b). 
An owner or operator of an affected facility subject to the opacity 
standard in Sec. 60.42Da(b) shall monitor the opacity of emissions 
discharged from the affected facility to the atmosphere according to the 
requirements in Sec. 60.49Da(a), as applicable to the affected 
facility.
    (r) Compliance provisions for sources subject to Sec. 60.45Da. To 
determine compliance with the NOX plus CO emissions limit, 
the owner or operator shall use the procedures specified in paragraphs 
(r)(1) through (3) of this section.
    (1) Calculate NOX emissions as 1.194 x 10-7 
lb/scf-ppm times the average hourly NOX output concentration 
in ppm (measured according to the provisions of Sec. 60.49Da(c)), times 
the average hourly flow rate (measured in scfh, according to the 
provisions of Sec. 60.49Da(l) or Sec. 60.49Da(m)), divided by the 
average

[[Page 193]]

hourly gross energy output (measured according to the provisions of 
Sec. 60.49Da(k)) or the average hourly net energy output, as 
applicable.
    (2) Calculate CO emissions by multiplying the average hourly CO 
output concentration (measured according to the provisions of Sec. 
60.49Da(u), by the average hourly flow rate (measured according to the 
provisions of Sec. 60.49Da(l) or Sec. 60.49Da(m)), and dividing by the 
average hourly gross energy output (measured according to the provisions 
of Sec. 60.49Da(k)) or the average hourly net energy output, as 
applicable.
    (3) Calculate NOX plus CO emissions by summing the 
NOX emissions results from paragraph (r)(1) of this section 
plus the CO emissions results from paragraph (r)(2) of this section.
    (s) Affirmative defense for exceedance of emissions limit during 
malfunction. In response to an action to enforce the standards set forth 
in paragraph Sec. Sec. 60.42Da, 60.43Da, 60.44Da, and 60.45Da, you may 
assert an affirmative defense to a claim for civil penalties for 
exceedances of such standards that are caused by malfunction, as defined 
at 40 CFR 60.2. Appropriate penalties may be assessed, however, if you 
fail to meet your burden of proving all of the requirements in the 
affirmative defense as specified in paragraphs (s)(1) and (2) of this 
section. The affirmative defense shall not be available for claims for 
injunctive relief.
    (1) To establish the affirmative defense in any action to enforce 
such a limit, you must timely meet the notification requirements in 
paragraph (s)(2) of this section, and must prove by a preponderance of 
evidence that:
    (i) The excess emissions:
    (A) Were caused by a sudden, infrequent, and unavoidable failure of 
air pollution control and monitoring equipment, process equipment, or a 
process to operate in a normal or usual manner; and
    (B) Could not have been prevented through careful planning, proper 
design, or better operation and maintenance practices; and
    (C) Did not stem from any activity or event that could have been 
foreseen and avoided, or planned for; and
    (D) Were not part of a recurring pattern indicative of inadequate 
design, operation, or maintenance; and
    (ii) Repairs were made as expeditiously as possible when the 
applicable emissions limits were being exceeded. Off-shift and overtime 
labor were used, to the extent practicable to make these repairs; and
    (iii) The frequency, amount, and duration of the excess emissions 
(including any bypass) were minimized to the maximum extent practicable 
during periods of such emissions; and
    (iv) If the excess emissions resulted from a bypass of control 
equipment or a process, then the bypass was unavoidable to prevent loss 
of life, personal injury, or severe property damage; and
    (v) All possible steps were taken to minimize the impact of the 
excess emissions on ambient air quality, the environment, and human 
health; and
    (vi) All emissions monitoring and control systems were kept in 
operation if at all possible, consistent with safety and good air 
pollution control practices; and
    (vii) All of the actions in response to the excess emissions were 
documented by properly signed, contemporaneous operating logs; and
    (viii) At all times, the facility was operated in a manner 
consistent with good practices for minimizing emissions; and
    (ix) A written root cause analysis has been prepared, the purpose of 
which is to determine, correct, and eliminate the primary causes of the 
malfunction and the excess emissions resulting from the malfunction 
event at issue. The analysis shall also specify, using best monitoring 
methods and engineering judgment, the amount of excess emissions that 
were the result of the malfunction.
    (2) Notification. The owner or operator of the affected source 
experiencing an exceedance of its emission limit(s) during a malfunction 
shall notify the Administrator by telephone or facsimile (FAX) 
transmission as soon as possible, but no later than two business days 
after the initial occurrence of the malfunction or, if it is not 
possible to determine within two business days whether the malfunction 
caused or contributed to an exceedance, no later

[[Page 194]]

than two business days after the owner or operator knew or should have 
known that the malfunction caused or contributed to an exceedance, but, 
in no event later than two business days after the end of the averaging 
period, if it wishes to avail itself of an affirmative defense to civil 
penalties for that malfunction. The owner or operator seeking to assert 
an affirmative defense shall also submit a written report to the 
Administrator within 45 days of the initial occurrence of the exceedance 
of the standard in Sec. 63.9991 to demonstrate, with all necessary 
supporting documentation, that it has met the requirements set forth in 
paragraph (s)(1) of this section. The owner or operator may seek an 
extension of this deadline for up to 30 additional days by submitting a 
written request to the Administrator before the expiration of the 45 day 
period. Until a request for an extension has been approved by the 
Administrator, the owner or operator is subject to the requirement to 
submit such report within 45 days of the initial occurrence of the 
exceedance.

Sec. 60.49Da  Emission monitoring.

    (a) An owner or operator of an affected facility subject to the 
opacity standard in Sec. 60.42Da must monitor the opacity of emissions 
discharged from the affected facility to the atmosphere according to the 
applicable requirements in paragraphs (a)(1) through (4) of this 
section.
    (1) Except as provided for in paragraphs (a)(2) and (4) of this 
section, the owner or operator of an affected facility subject to an 
opacity standard, shall install, calibrate, maintain, and operate a 
COMS, and record the output of the system, for measuring the opacity of 
emissions discharged to the atmosphere. If opacity interference due to 
water droplets exists in the stack (for example, from the use of an FGD 
system), the opacity is monitored upstream of the interference (at the 
inlet to the FGD system). If opacity interference is experienced at all 
locations (both at the inlet and outlet of the SO2 control 
system), alternate parameters indicative of the PM control system's 
performance and/or good combustion are monitored (subject to the 
approval of the Administrator).
    (2) As an alternative to the monitoring requirements in paragraph 
(a)(1) of this section, an owner or operator of an affected facility 
that meets the conditions in either paragraph (a)(2)(i), (ii), (iii), or 
(iv) of this section may elect to monitor opacity as specified in 
paragraph (a)(3) of this section.
    (i) The affected facility uses a fabric filter (baghouse) to meet 
the standards in Sec. 60.42Da and a bag leak detection system is 
installed and operated according to the requirements in paragraphs Sec. 
60.48Da(o)(4)(i) through (v);
    (ii) The affected facility burns only gaseous or liquid fuels 
(excluding residual oil) with potential SO2 emissions rates 
of 26 ng/J (0.060 lb/MMBtu) or less, and does not use a post-combustion 
technology to reduce emissions of SO2 or PM;
    (iii) The affected facility meets all of the conditions specified in 
paragraphs (a)(2)(iii)(A) through (C) of this section.
    (A) No post-combustion technology (except a wet scrubber) is used 
for reducing PM, SO2, or CO emissions;
    (B) Only natural gas, gaseous fuels, or fuel oils that contain less 
than or equal to 0.30 weight percent sulfur are burned; and
    (C) Emissions of CO discharged to the atmosphere are maintained at 
levels less than or equal to 1.4 lb/MWh on a boiler operating day 
average basis as demonstrated by the use of a CEMS measuring CO 
emissions according to the procedures specified in paragraph (u) of this 
section; or
    (iv) The affected facility uses an ESP and uses an ESP predictive 
model to monitor the performance of the ESP developed in accordance and 
operated according to the most current requirements in section Sec. 
60.48Da of this part.
    (3) The owner or operator of an affected facility that meets the 
conditions in paragraph (a)(2) of this section may, as an alternative to 
using a COMS, elect to monitor visible emissions using the applicable 
procedures specified in paragraphs (a)(3)(i) through (iv) of this 
section. The opacity performance test requirement in paragraph (a)(3)(i) 
must be conducted by

[[Page 195]]

April 29, 2011, within 45 days after stopping use of an existing COMS, 
or within 180 days after initial startup of the facility, whichever is 
later.
    (i) The owner or operator shall conduct a performance test using 
Method 9 of appendix A-4 of this part and the procedures in Sec. 60.11. 
If during the initial 60 minutes of the observation all the 6-minute 
averages are less than 10 percent and all the individual 15-second 
observations are less than or equal to 20 percent, then the observation 
period may be reduced from 3 hours to 60 minutes.
    (ii) Except as provided in paragraph (a)(3)(iii) or (iv) of this 
section, the owner or operator shall conduct subsequent Method 9 of 
appendix A-4 of this part performance tests using the procedures in 
paragraph (a)(3)(i) of this section according to the applicable schedule 
in paragraphs (a)(3)(ii)(A) through (a)(3)(ii)(C) of this section, as 
determined by the most recent Method 9 of appendix A-4 of this part 
performance test results.
    (A) If the maximum 6-minute average opacity is less than or equal to 
5 percent, a subsequent Method 9 of appendix A-4 of this part 
performance test must be completed within 12 calendar months from the 
date that the most recent performance test was conducted or within 45 
days of the next day that fuel with an opacity standard is combusted, 
whichever is later;
    (B) If the maximum 6-minute average opacity is greater than 5 
percent but less than or equal to 10 percent, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 3 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later; or
    (C) If the maximum 6-minute average opacity is greater than 10 
percent, a subsequent Method 9 of appendix A-4 of this part performance 
test must be completed within 45 calendar days from the date that the 
most recent performance test was conducted.
    (iii) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 of this part performance tests, elect to 
perform subsequent monitoring using Method 22 of appendix A-7 of this 
part according to the procedures specified in paragraphs (a)(3)(iii)(A) 
and (B) of this section.
    (A) The owner or operator shall conduct 10 minute observations 
(during normal operation) each operating day the affected facility fires 
fuel for which an opacity standard is applicable using Method 22 of 
appendix A-7 of this part and demonstrate that the sum of the 
occurrences of any visible emissions is not in excess of 5 percent of 
the observation period (i.e., 30 seconds per 10 minute period). If the 
sum of the occurrence of any visible emissions is greater than 30 
seconds during the initial 10 minute observation, immediately conduct a 
30 minute observation. If the sum of the occurrence of visible emissions 
is greater than 5 percent of the observation period (i.e., 90 seconds 
per 30 minute period), the owner or operator shall either document and 
adjust the operation of the facility and demonstrate within 24 hours 
that the sum of the occurrence of visible emissions is equal to or less 
than 5 percent during a 30 minute observation (i.e., 90 seconds) or 
conduct a new Method 9 of appendix A-4 of this part performance test 
using the procedures in paragraph (a)(3)(i) of this section within 45 
calendar days according to the requirements in Sec. 60.50Da(b)(3).
    (B) If no visible emissions are observed for 10 operating days 
during which an opacity standard is applicable, observations can be 
reduced to once every 7 operating days during which an opacity standard 
is applicable. If any visible emissions are observed, daily observations 
shall be resumed.
    (iv) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 performance tests, elect to perform subsequent 
monitoring using a digital opacity compliance system according to a 
site-specific monitoring plan approved by the

[[Page 196]]

Administrator. The observations must be similar, but not necessarily 
identical, to the requirements in paragraph (a)(3)(iii) of this section. 
For reference purposes in preparing the monitoring plan, see OAQPS 
``Determination of Visible Emission Opacity from Stationary Sources 
Using Computer-Based Photographic Analysis Systems.'' This document is 
available from the U.S. Environmental Protection Agency (U.S. EPA); 
Office of Air Quality and Planning Standards; Sector Policies and 
Programs Division; Measurement Policy Group (D243-02), Research Triangle 
Park, NC 27711. This document is also available on the Technology 
Transfer Network (TTN) under Emission Measurement Center Preliminary 
Methods.
    (4) An owner or operator of an affected facility that is subject to 
an opacity standard under Sec. 60.42Da is not required to operate a 
COMS provided that affected facility meets the conditions in either 
paragraph (a)(4)(i) or (ii) of this section.
    (i) The affected facility combusts only gaseous and/or liquid fuels 
(excluding residue oil) where the potential SO2 emissions 
rate of each fuel is no greater than 26 ng/J (0.060 lb/MMBtu), and the 
unit operates according to a written site-specific monitoring plan 
approved by the permitting authority. This monitoring plan must include 
procedures and criteria for establishing and monitoring specific 
parameters for the affected facility indicative of compliance with the 
opacity standard. For testing performed as part of this site-specific 
monitoring plan, the permitting authority may require as an alternative 
to the notification and reporting requirements specified in Sec. Sec. 
60.8 and 60.11 that the owner or operator submit any deviations with the 
excess emissions report required under Sec. 60.51Da(d).
    (ii) The owner or operator of the affected facility installs, 
calibrates, operates, and maintains a particulate matter continuous 
parametric monitoring system (PM CPMS) according to the requirements 
specified in subpart UUUUU of part 63.
    (b) The owner or operator of an affected facility must install, 
calibrate, maintain, and operate a CEMS, and record the output of the 
system, for measuring SO2 emissions, except where only 
gaseous and/or liquid fuels (excluding residual oil) where the potential 
SO2 emissions rate of each fuel is 26 ng/J (0.060 lb/MMBtu) 
or less are combusted, as follows:
    (1) Sulfur dioxide emissions are monitored at both the inlet and 
outlet of the SO2 control device.
    (2) For a facility that qualifies under the numerical limit 
provisions of Sec. 60.43Da, SO2 emissions are only monitored 
as discharged to the atmosphere.
    (3) An ``as fired'' fuel monitoring system (upstream of coal 
pulverizers) meeting the requirements of Method 19 of appendix A of this 
part may be used to determine potential SO2 emissions in 
place of a continuous SO2 emission monitor at the inlet to 
the SO2 control device as required under paragraph (b)(1) of 
this section.
    (4) If the owner or operator has installed and certified a 
SO2 CEMS according to the requirements of Sec. 75.20(c)(1) 
of this chapter and appendix A to part 75 of this chapter, and is 
continuing to meet the ongoing quality assurance requirements of Sec. 
75.21 of this chapter and appendix B to part 75 of this chapter, that 
CEMS may be used to meet the requirements of this section, provided 
that:
    (i) A CO2 or O2 continuous monitoring system 
is installed, calibrated, maintained and operated at the same location, 
according to paragraph (d) of this section; and
    (ii) For sources subject to an SO2 emission limit in lb/
MMBtu under Sec. 60.43Da:
    (A) When relative accuracy testing is conducted, SO2 
concentration data and CO2 (or O2) data are 
collected simultaneously; and
    (B) In addition to meeting the applicable SO2 and 
CO2 (or O2) relative accuracy specifications in 
Figure 2 of appendix B to part 75 of this chapter, the relative accuracy 
(RA) standard in section 13.2 of Performance Specification 2 in appendix 
B to this part is met when the RA is calculated on a lb/MMBtu basis; and
    (iii) The reporting requirements of Sec. 60.51Da are met. The 
SO2 and, if required, CO2 (or O2) data 
reported to meet the requirements of Sec. 60.51Da shall not include 
substitute data values

[[Page 197]]

derived from the missing data procedures in subpart D of part 75 of this 
chapter, nor shall the SO2 data have been bias adjusted 
according to the procedures of part 75 of this chapter.
    (c)(1) The owner or operator of an affected facility shall install, 
calibrate, maintain, and operate a CEMS, and record the output of the 
system, for measuring NOX emissions discharged to the 
atmosphere; or
    (2) If the owner or operator has installed a NOX emission 
rate CEMS to meet the requirements of part 75 of this chapter and is 
continuing to meet the ongoing requirements of part 75 of this chapter, 
that CEMS may be used to meet the requirements of this section, except

an output based limit shall install, calibrate, maintain, and operate a 
CEMS, and record the output of the system, for measuring the 
O2 or carbon dioxide (CO2) content of the flue 
gases at each location where SO2 or NOX emissions 
are monitored. For affected facilities subject to a lb/MMBtu 
SO2 emission limit under Sec. 60.43Da, if the owner or 
operator has installed and certified a CO2 or O2 
monitoring system according to Sec. 75.20(c) of this chapter and 
appendix A to part 75 of this chapter and the monitoring system 
continues to meet the applicable quality-assurance provisions of Sec. 
75.21 of this chapter and appendix B to part 75 of this chapter, that 
CEMS may be used together with the part 75 SO2 concentration 
monitoring system described in paragraph (b) of this section, to 
determine the SO2 emission rate in lb/MMBtu. SO2 
data used to meet the requirements of Sec. 60.51Da shall not include 
substitute data values derived from the missing data procedures in 
subpart D of part 75 of this chapter, nor shall the data have been bias 
adjusted according to the procedures of part 75 of this chapter.
    (e) The CEMS under paragraphs (b), (c), and (d) of this section are 
operated and data recorded during all periods of operation of the 
affected facility including periods of startup, shutdown, and 
malfunction, except for CEMS breakdowns, repairs, calibration checks, 
and zero and span adjustments.

modification on or before February 28, 2005, the owner or operator shall 
obtain emission data for at least 18 hours in at least 22 out of 30 
successive boiler operating days. If this minimum data requirement 
cannot be met with CEMS, the owner or operator shall supplement emission 
data with other monitoring systems approved by the Administrator or the 
reference methods and procedures as described in paragraph (h) of this 
section.
    (2) For units that began construction, reconstruction, or 
modification after February 28, 2005, the owner or operator shall obtain 
emission data for at least 90 percent of all operating hours for each 30 
successive boiler operating days. If this minimum data requirement 
cannot be met with a CEMS, the owner or operator shall supplement 
emission data with other monitoring systems approved by the 
Administrator or the reference methods and procedures as described in 
paragraph (h) of this section.
    (g) The 1-hour averages required under paragraph Sec. 60.13(h) are 
expressed in ng/J (lb/MMBtu) heat input and used to calculate the 
average emission rates under Sec. 60.48Da. The 1-hour averages are 
calculated using the data points required under Sec. 60.13(h)(2).
    (h) When it becomes necessary to supplement CEMS data to meet the 
minimum data requirements in paragraph (f) of this section, the owner or 
operator shall use the reference methods and procedures as specified in 
this paragraph. Acceptable alternative methods and procedures are given 
in paragraph (j) of this section.
    (1) Method 6 of appendix A of this part shall be used to determine 
the SO2 concentration at the same location as the 
SO2 monitor. Samples shall be taken at 60-minute intervals. 
The sampling time and sample volume for each sample shall be at least 20 
minutes and

[[Page 198]]

0.020 dscm (0.71 dscf). Each sample represents a 1-hour average.
    (2) Method 7 of appendix A of this part shall be used to determine 
the NOX concentration at the same location as the 
NOX monitor. Samples shall be taken at 30-minute intervals. 
The arithmetic average of two consecutive samples represents a 1-hour 
average.
    (3) The emission rate correction factor, integrated bag sampling and 
analysis procedure of Method 3B of appendix A of this part shall be used 
to determine the O2 or CO2 concentration at the 
same location as the O2 or CO2 monitor. Samples 
shall be taken for at least 30 minutes in each hour. Each sample 
represents a 1-hour average.
    (4) The procedures in Method 19 of appendix A of this part shall be 
used to compute each 1-hour average concentration in ng/J (lb/MMBtu) 
heat input.
    (i) The owner or operator shall use methods and procedures in this 
paragraph to conduct monitoring system performance evaluations under 
Sec. 60.13(c) and calibration checks under Sec. 60.13(d). Acceptable 
alternative methods and procedures are given in paragraph (j) of this 
section.

used for preparing the calibration gas mixtures (in N2, as 
applicable) under Performance Specification 2 of appendix B of this 
part.
    (3) For affected facilities burning only fossil fuel, the span value 
for a COMS is between 60 and 80 percent. Span values for a CEMS 
measuring NOX shall be determined using one of the following 
procedures:
    (i) Except as provided under paragraph (i)(3)(ii) of this section, 
NOX span values shall be determined as follows:

------------------------------------------------------------------------
             Fossil fuel                   Span values for NOX (ppm)
------------------------------------------------------------------------
Gas.................................  500.
Liquid..............................  500.
Solid...............................  1,000.
Combination.........................  500 (x + y) + 1,000z.
------------------------------------------------------------------------

Where:

x = Fraction of total heat input derived from gaseous fossil fuel,
y = Fraction of total heat input derived from liquid fossil fuel, and
z = Fraction of total heat input derived from solid fossil fuel.

    (ii) As an alternative to meeting the requirements of paragraph

may elect to use the NOX span values determined according to 
section 2.1.2 in appendix A to part 75 of this chapter.
    (4) All span values computed under paragraph (i)(3)(i) of this 
section for burning combinations of fossil fuels are rounded to the 
nearest 500 ppm. Span values computed under paragraph (i)(3)(ii) of this 
section shall be rounded off according to section 2.1.2 in appendix A to 
part 75 of this chapter.
    (5) For affected facilities burning fossil fuel, alone or in 
combination with non-fossil fuel and determining span values under 
paragraph (i)(3)(i) of this section, the span value of the 
SO2 CEMS at the inlet to the SO2 control device is 
125 percent of the maximum estimated hourly potential emissions of the 
fuel fired, and the outlet of the SO2 control device is 50 
percent of maximum estimated hourly potential emissions of the fuel 
fired. For affected facilities determining span values under paragraph 
(i)(3)(ii) of this section, SO2 span values shall be 
determined according to section 2.1.1 in appendix A to part 75 of this 
chapter.
    (j) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:

(whenever Methods 6 and 3 or 3B of appendix A of this part data are 
used) or 6C of appendix A of this part may be used. Each Method 6B of 
appendix A of this part sample obtained over 24 hours represents 24 1-
hour averages. If Method 6A or 6B of appendix A of this part is used 
under paragraph (i) of this section, the conditions under Sec. 
60.48Da(d)(1) apply; these conditions do not apply under paragraph (h) 
of this section.

with electrical generation, the gross energy output is determined 
according to the definition of ``gross energy output'' specified in 
Sec. 60.41Da that is applicable to the affected facility.
    (l) The owner or operator of an affected facility demonstrating 
compliance with an output-based standard shall install, certify, 
operate, and maintain a continuous flow monitoring system meeting the 
requirements of Performance Specification 6 of appendix B of this part 
and the calibration drift (CD) assessment, relative accuracy test audit 
(RATA), and reporting provisions of procedure 1 of appendix F of this 
part, and record the output of the system, for measuring the volumetric 
flow rate of exhaust gases discharged to the atmosphere; or
    (m) Alternatively, data from a continuous flow monitoring system 
certified according to the requirements of Sec. 75.20(c) of this 
chapter and appendix A to part 75 of this chapter, and continuing to 
meet the applicable quality control and quality assurance requirements 
of Sec. 75.21 of this chapter and appendix B to part 75 of this 
chapter, may be used. Flow rate data reported to meet the requirements 
of Sec. 60.51Da shall not include substitute data values derived from 
the missing data procedures in subpart D of part 75 of this chapter, nor 
shall the data have been bias adjusted according to the procedures of 
part 75 of this chapter.
    (n) Gas-fired and oil-fired units. The owner or operator of an 
affected unit that qualifies as a gas-fired or oil-fired unit, as 
defined in 40 CFR 72.2, may use, as an alternative to the requirements 
specified in either paragraph (l) or (m) of this section, a fuel flow 
monitoring system certified and operated according to the requirements 
of appendix D of part 75 of this chapter.
    (o) The owner or operator of a duct burner, as described in Sec. 
60.41Da, which is subject to the NOX standards of Sec.

CEMS to measure NOX emissions; a wattmeter to measure gross 
electrical output; meters to measure steam flow, temperature, and 
pressure; and a continuous flow monitoring system to measure the flow of 
exhaust gases discharged to the atmosphere.
    (p)-(r) [Reserved]
    (s) The owner or operator shall prepare and submit to the 
Administrator for approval a unit-specific monitoring plan for each 
monitoring system, at least 45 days before commencing certification 
testing of the monitoring systems. The owner or operator shall comply 
with the requirements in your plan. The plan must address the 
requirements in paragraphs (s)(1) through (6) of this section.

Sec. 60.50Da  Compliance determination procedures and methods.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the 
methods in appendix A of this part or the methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b). Section 
60.8(f) does not apply to this section for SO2 and 
NOX. Acceptable alternative methods are given in paragraph 
(e) of this section.
    (b) In conducting the performance tests to determine compliance with 
the PM emissions limits in Sec. 60.42Da, the owner or operator shall 
meet the requirements specified in paragraphs (b)(1) through (3) of this 
section.
    (1) The owner or operator shall measure filterable PM to determine 
compliance with the applicable PM emissions limit in Sec. 60.42Da as 
specified in paragraphs (b)(1)(i) through (ii) of this section.
    (i) The dry basis F factor (O2) procedures in Method 19 
of appendix A of this part shall be used to compute the emission rate of 
PM.
    (ii) For the PM concentration, Method 5 of appendix A of this part 
shall be used for an affected facility that does not use a wet FGD. For 
an affected facility that uses a wet FGD, Method 5B of appendix A of 
this part shall be used downstream of the wet FGD.
    (A) The sampling time and sample volume for each run shall be at 
least 120 minutes and 1.70 dscm (60 dscf). The probe and filter holder 
heating system in the sampling train may be set to provide an average 
gas temperature of no greater than 160 14 [deg]C (320 25 [deg]F).
    (B) For each particulate run, the emission rate correction factor, 
integrated or grab sampling and analysis procedures of Method 3B of 
appendix A of this part shall be used to determine the O2 
concentration. The O2 sample shall be obtained simultaneously 
with, and at the same traverse points as, the particulate run. If the 
particulate run

[[Page 203]]

has more than 12 traverse points, the O2 traverse points may 
be reduced to 12 provided that Method 1 of appendix A of this part is 
used to locate the 12 O2 traverse points. If the grab 
sampling procedure is used, the O2 concentration for the run 
shall be the arithmetic mean of the sample O2 concentrations 
at all traverse points.
    (2) In conjunction with a performance test performed according to 
the requirements in paragraph (b)(1) of this section, the owner or 
operator of an affected facility for which construction, reconstruction, 
or modification commenced after May 3, 2011, shall measure condensable 
PM using Method 202 of appendix M of part 51.
    (3) Method 9 of appendix A of this part and the procedures in Sec. 
60.11 shall be used to determine opacity.
    (c) The owner or operator shall determine compliance with the 
SO2 standards in Sec. 60.43Da as follows:
    (1) The percent of potential SO2 emissions (%Ps) to the 
atmosphere shall be computed using the following equation:
[GRAPHIC] [TIFF OMITTED] TR13JN07.015

Where:

%Ps = Percent of potential SO2 emissions, percent;
%Rf = Percent reduction from fuel pretreatment, percent; and
%Rg = Percent reduction by SO2 control system, percent.

    (2) The procedures in Method 19 of appendix A of this part may be 
used to determine percent reduction (%Rf) of sulfur by such 
processes as fuel pretreatment (physical coal cleaning, 
hydrodesulfurization of fuel oil, etc.), coal pulverizers, and bottom 
and fly ash interactions. This determination is optional.
    (3) The procedures in Method 19 of appendix A of this part shall be 
used to determine the percent SO2 reduction (%Rg) 
of any SO2 control system. Alternatively, a combination of an 
``as fired'' fuel monitor and emission rates measured after the control 
system, following the procedures in Method 19 of appendix A of this 
part, may be used if the percent reduction is calculated using the 
average emission rate from the SO2 control device and the 
average SO2 input rate from the ``as fired'' fuel analysis 
for 30 successive boiler operating days.
    (4) The appropriate procedures in Method 19 of appendix A of this 
part shall be used to determine the emission rate.
    (5) The CEMS in Sec. 60.49Da(b) and (d) shall be used to determine 
the concentrations of SO2 and CO2 or 
O2.
    (d) The owner or operator shall determine compliance with the 
NOX standard in Sec. 60.44Da as follows:
    (1) The appropriate procedures in Method 19 of appendix A of this 
part shall be used to determine the emission rate of NOX.
    (2) The continuous monitoring system in Sec. 60.49Da(c) and (d) 
shall be used to determine the concentrations of NOX and 
CO2 or O2.
    (e) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) For Method 5 or 5B of appendix A-3 of this part, Method 17 of 
appendix A-6 of this part may be used at facilities with or without wet 
FGD systems if the stack temperature at the sampling location does not 
exceed an average temperature of 160 [deg]C (320 [deg]F). The procedures 
of sections 8.1 and 11.1 of Method 5B of appendix A-3 of this part may 
be used in Method 17 of appendix A-6 of this part only if it is used 
after wet FGD systems. Method 17 of appendix A-6 of this part shall not 
be used after wet FGD systems if the effluent is saturated or laden with 
water droplets.
    (2) The Fc factor (CO2) procedures in Method 
19 of appendix A of this part may be used to compute the emission rate 
of PM under the stipulations of Sec. 60.46(d)(1). The CO2 
shall be determined in the same manner as the O2 
concentration.
    (f) The owner or operator of an electric utility combined cycle gas 
turbine that does not meet the definition of an IGCC must conduct 
performance tests for PM, SO2, and NOX using the 
procedures of Method 19 of appendix A-7 of this part. The SO2 
and NOX emission rates calculations from the gas turbine used 
in Method 19 of appendix A-7 of this part are determined when the gas 
turbine is performance tested under subpart GG of this part. The 
potential

[[Page 204]]

uncontrolled PM emission rate from a gas turbine is defined as 17 ng/J 
(0.04 lb/MMBtu) heat input.

Where:

En = NOX emission limit (expressed as 
          NO2), ng/J (lb/MMBtu);
ELgo = Appropriate emission limit from paragraph (a)(1) for 
          combustion of natural gas or distillate oil, ng/J (lb/MMBtu);
Hgo = Heat input from combustion of natural gas or distillate 
          oil, J (MMBtu);

[[Page 217]]

ELro = Appropriate emission limit from paragraph (a)(2) for 
          combustion of residual oil, ng/J (lb/MMBtu);
Hro = Heat input from combustion of residual oil, J (MMBtu);
ELc = Appropriate emission limit from paragraph (a)(3) for 
          combustion of coal, ng/J (lb/MMBtu); and
Hc = Heat input from combustion of coal, J (MMBtu).

    (c) Except as provided under paragraph (d) and (l) of this section, 
on and after the date on which the initial performance test is completed 
or is required to be completed under Sec. 60.8, whichever date comes 
first, no owner or operator of an affected facility that simultaneously 
combusts coal or oil, natural gas (or any combination of the three), and 
wood, or any other fuel shall cause to be discharged into the atmosphere 
any gases that contain NOX in excess of the emission limit 
for the coal, oil, natural gas (or any combination of the three), 
combusted in the affected facility, as determined pursuant to paragraph 
(a) or (b) of this section. This standard does not apply to an affected 
facility that is subject to and in compliance with a federally 
enforceable requirement that limits operation of the affected facility 
to an annual capacity factor of 10 percent (0.10) or less for coal, oil, 
natural gas (or any combination of the three).
    (d) On and after the date on which the initial performance test is 
completed or is required to be completed under Sec. 60.8, whichever 
date comes first, no owner or operator of an affected facility that 
simultaneously combusts natural gas and/or distillate oil with a 
potential SO2 emissions rate of 26 ng/J (0.060 lb/MMBtu) or 
less with wood, municipal-type solid waste, or other solid fuel, except 
coal, shall cause to be discharged into the atmosphere from that 
affected facility any gases that contain NOX in excess of 130 
ng/J (0.30 lb/MMBtu) heat input unless the affected facility has an 
annual capacity factor for natural gas, distillate oil, or a mixture of 
these fuels of 10 percent (0.10) or less and is subject to a federally 
enforceable requirement that limits operation of the affected facility 
to an annual capacity factor of 10 percent (0.10) or less for natural 
gas, distillate oil, or a mixture of these fuels.
    (e) Except as provided under paragraph (l) of this section, on and 
after the date on which the initial performance test is completed or is 
required to be completed under Sec. 60.8, whichever date comes first, 
no owner or operator of an affected facility that simultaneously 
combusts only coal, oil, or natural gas with byproduct/waste shall cause 
to be discharged into the atmosphere any gases that contain 
NOX in excess of the emission limit determined by the 
following formula unless the affected facility has an annual capacity 
factor for coal, oil, and natural gas of 10 percent (0.10) or less and 
is subject to a federally enforceable requirement that limits operation 
of the affected facility to an annual capacity factor of 10 percent 
(0.10) or less:
    (f) Any owner or operator of an affected facility that combusts 
byproduct/waste with either natural gas or oil may petition the 
Administrator within 180 days of the initial startup of the affected 
facility to establish a NOX emission limit that shall apply 
specifically to that affected facility when the byproduct/waste is 
combusted. The petition shall include sufficient and appropriate data, 
as determined by the Administrator, such as NOX emissions 
from the affected facility, waste composition (including nitrogen 
content), and combustion conditions to allow the Administrator to 
confirm that the affected facility is unable to comply with the emission 
limits in paragraph (e) of this section and to determine the appropriate 
emission limit for the affected facility.
    (1) Any owner or operator of an affected facility petitioning for a 
facility-specific NOX emission limit under this section 
shall:
    (i) Demonstrate compliance with the emission limits for natural gas 
and distillate oil in paragraph (a)(1) of this section or for residual 
oil in paragraph (a)(2) or (l)(1) of this section, as appropriate, by 
conducting a 30-day performance test as provided in Sec. 60.46b(e). 
During the performance test only natural gas, distillate oil, or 
residual oil shall be combusted in the affected facility; and
    (ii) Demonstrate that the affected facility is unable to comply with 
the

[[Page 218]]

emission limits for natural gas and distillate oil in paragraph (a)(1) 
of this section or for residual oil in paragraph (a)(2) or (l)(1) of 
this section, as appropriate, when gaseous or liquid byproduct/waste is 
combusted in the affected facility under the same conditions and using 
the same technological system of emission reduction applied when 
demonstrating compliance under paragraph (f)(1)(i) of this section.
    (2) The NOX emission limits for natural gas or distillate 
oil in paragraph (a)(1) of this section or for residual oil in paragraph 
(a)(2) or (l)(1) of this section, as appropriate, shall be applicable to 
the affected facility until and unless the petition is approved by the 
Administrator. If the petition is approved by the Administrator, a 
facility-specific NOX emission limit will be established at 
the NOX emission level achievable when the affected facility 
is combusting oil or natural gas and byproduct/waste in a manner that 
the Administrator determines to be consistent with minimizing 
NOX emissions. In lieu of amending this subpart, a letter 
will be sent to the facility describing the facility-specific 
NOX limit. The facility shall use the compliance procedures 
detailed in the letter and make the letter available to the public. If 
the Administrator determines it is appropriate, the conditions and 
requirements of the letter can be reviewed and changed at any point.
    (g) Any owner or operator of an affected facility that combusts 
hazardous waste (as defined by 40 CFR part 261 or 40 CFR part 761) with 
natural gas or oil may petition the Administrator within 180 days of the 
initial startup of the affected facility for a waiver from compliance 
with the NOX emission limit that applies specifically to that 
affected facility. The petition must include sufficient and appropriate 
data, as determined by the Administrator, on NOX emissions 
from the affected facility, waste destruction efficiencies, waste 
composition (including nitrogen content), the quantity of specific 
wastes to be combusted and combustion conditions to allow the 
Administrator to determine if the affected facility is able to comply 
with the NOX emission limits required by this section. The 
owner or operator of the affected facility shall demonstrate that when 
hazardous waste is combusted in the affected facility, thermal 
destruction efficiency requirements for hazardous waste specified in an 
applicable federally enforceable requirement preclude compliance with 
the NOX emission limits of this section. The NOX 
emission limits for natural gas or distillate oil in paragraph (a)(1) of 
this section or for residual oil in paragraph (a)(2) or (l)(1) of this 
section, as appropriate, are applicable to the affected facility until 
and unless the petition is approved by the Administrator. (See 40 CFR 
761.70 for regulations applicable to the incineration of materials 
containing polychlorinated biphenyls (PCB's).) In lieu of amending this 
subpart, a letter will be sent to the facility describing the facility-
specific NOX limit. The facility shall use the compliance 
procedures detailed in the letter and make the letter available to the 
public. If the Administrator determines it is appropriate, the 
conditions and requirements of the letter can be reviewed and changed at 
any point.
    (h) For purposes of paragraph (i) of this section, the 
NOX standards under this section apply at all times including 
periods of startup, shutdown, or malfunction.
    (i) Except as provided under paragraph (j) of this section, 
compliance with the emission limits under this section is determined on 
a 30-day rolling average basis.
    (j) Compliance with the emission limits under this section is 
determined on a 24-hour average basis for the initial performance test 
and on a 3-hour average basis for subsequent performance tests for any 
affected facilities that:
    (1) Combust, alone or in combination, only natural gas, distillate 
oil, or residual oil with a nitrogen content of 0.30 weight percent or 
less;
    (2) Have a combined annual capacity factor of 10 percent or less for 
natural gas, distillate oil, and residual oil with a nitrogen content of 
0.30 weight percent or less; and
    (3) Are subject to a federally enforceable requirement limiting 
operation of the affected facility to the firing of natural gas, 
distillate oil, and/or residual oil with a nitrogen content of 0.30

[[Page 219]]

weight percent or less and limiting operation of the affected facility 
to a combined annual capacity factor of 10 percent or less for natural 
gas, distillate oil, and residual oil with a nitrogen content of 0.30 
weight percent or less.
    (k) Affected facilities that meet the criteria described in 
paragraphs (j)(1), (2), and (3) of this section, and that have a heat 
input capacity of 73 MW (250 MMBtu/hr) or less, are not subject to the 
NOX emission limits under this section.
    (l) On and after the date on which the initial performance test is 
completed or is required to be completed under 60.8, whichever date is 
first, no owner or operator of an affected facility that commenced 
construction after July 9, 1997 shall cause to be discharged into the 
atmosphere from that affected facility any gases that contain NOx 
(expressed as NO2) in excess of the following limits:
    (1) 86 ng/J (0.20 lb/MMBtu) heat input if the affected facility 
combusts coal, oil, or natural gas (or any combination of the three), 
alone or with any other fuels. The affected facility is not subject to 
this limit if it is subject to and in compliance with a federally 
enforceable requirement that limits operation of the facility to an 
annual capacity factor of 10 percent (0.10) or less for coal, oil, and 
natural gas (or any combination of the three); or
    (2) If the affected facility has a low heat release rate and 
combusts natural gas or distillate oil in excess of 30 percent of the 
heat input on a 30-day rolling average from the combustion of all fuels, 
a limit determined by use of the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.026

Where:

En = NOX emission limit, (lb/MMBtu);
Hgo = 30-day heat input from combustion of natural gas or 
          distillate oil; and
Hr = 30-day heat input from combustion of any other fuel.

    (3) After February 27, 2006, units where more than 10 percent of 
total annual output is electrical or mechanical may comply with an 
optional limit of 270 ng/J (2.1 lb/MWh) gross energy output, based on a 
30-day rolling average. Units complying with this output-based limit 
must demonstrate compliance according to the procedures of Sec. 
60.48Da(i) of subpart Da of this part, and must monitor emissions 
according to Sec. 60.49Da(c), (k), through (n) of subpart Da of this 
part.

60.8(b). Section 60.8(f) does not apply to this section. The 30-day 
notice required in Sec. 60.8(d) applies only to the initial performance 
test unless otherwise specified by the Administrator.
    (c) The owner or operator of an affected facility shall conduct 
performance tests to determine compliance with the percent of potential 
SO2 emission rate (% Ps) and the SO2 
emission rate (Es) pursuant to Sec. 60.42b following the 
procedures listed below, except as provided under paragraph (d) and (k) 
of this section.
    (1) The initial performance test shall be conducted over 30 
consecutive operating days of the steam generating unit. Compliance with 
the SO2 standards shall be determined using a 30-day average. 
The first operating day included in the initial performance test shall 
be scheduled within 30 days after achieving the maximum production rate 
at which the affected facility will be operated, but not later than 180 
days after initial startup of the facility.

[[Page 220]]

    (2) If only coal, only oil, or a mixture of coal and oil is 
combusted, the following procedures are used:
    (i) The procedures in Method 19 of appendix A-7 of this part are 
used to determine the hourly SO2 emission rate 
(Eho) and the 30-day average emission rate (Eao). 
The hourly averages used to compute the 30-day averages are obtained 
from the CEMS of Sec. 60.47b(a) or (b).
    (ii) The percent of potential SO2 emission rate 
(%Ps) emitted to the atmosphere is computed using the 
following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.027

Where:

%Ps = Potential SO2 emission rate, percent;
%Rg = SO2 removal efficiency of the control device 
          as determined by Method 19 of appendix A of this part, in 
          percent; and
%Rf = SO2 removal efficiency of fuel pretreatment 
          as determined by Method 19 of appendix A of this part, in 
          percent.

    (3) If coal or oil is combusted with other fuels, the same 
procedures required in paragraph (c)(2) of this section are used, except 
as provided in the following:
    (i) An adjusted hourly SO2 emission rate 
(Eho\o\) is used in Equation 19-19 of Method 19 of appendix A 
of this part to compute an adjusted 30-day average emission rate 
(Eao\o\). The Eho[deg] is computed using the following 
formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.028

Where:

Eho\o\ = Adjusted hourly SO2 emission rate, ng/J 
          (lb/MMBtu);
Eho = Hourly SO2 emission rate, ng/J (lb/MMBtu);
Ew = SO2 concentration in fuels other than coal 
          and oil combusted in the affected facility, as determined by 
          the fuel sampling and analysis procedures in Method 19 of 
          appendix A of this part, ng/J (lb/MMBtu). The value 
          Ew for each fuel lot is used for each hourly 
          average during the time that the lot is being combusted; and
Xk = Fraction of total heat input from fuel combustion 
          derived from coal, oil, or coal and oil, as determined by 
          applicable procedures in Method 19 of appendix A of this part.

    (ii) To compute the percent of potential SO2 emission 
rate (%Ps), an adjusted %Rg (%Rg\o\) is 
computed from the adjusted Eao\o\ from paragraph (b)(3)(i) of 
this section and an adjusted average SO2 inlet rate 
(Eai\o\) using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.029

    To compute Eai\o\, an adjusted hourly SO2 
inlet rate (Ehi\o\) is used. The Ehi\o\ is 
computed using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.030

Where:

Ehi\o\ = Adjusted hourly SO2 inlet rate, ng/J (lb/
          MMBtu); and
Ehi = Hourly SO2 inlet rate, ng/J (lb/MMBtu).

    (4) The owner or operator of an affected facility subject to 
paragraph (c)(3) of this section does not have to measure parameters 
Ew or Xk if the owner or operator elects to assume 
that Xk = 1.0. Owners or operators of affected facilities who 
assume Xk = 1.0 shall:
    (i) Determine %Ps following the procedures in paragraph 
(c)(2) of this section; and
    (ii) Sulfur dioxide emissions (Es) are considered to be 
in compliance with SO2 emission limits under Sec. 60.42b.
    (5) The owner or operator of an affected facility that qualifies 
under the provisions of Sec. 60.42b(d) does not have to measure 
parameters Ew or Xk in paragraph (c)(3) of this 
section if the owner or operator of the affected facility elects to 
measure SO2 emission rates of the coal or oil following the 
fuel sampling and analysis procedures in Method 19 of appendix A-7 of 
this part.
    (d) Except as provided in paragraph (j) of this section, the owner 
or operator of an affected facility that combusts only very low sulfur 
oil, natural gas, or a mixture of these fuels, has an annual capacity 
factor for oil of 10 percent (0.10) or less, and is subject to a 
federally enforceable requirement limiting operation of the affected 
facility to an annual capacity factor for oil of 10 percent (0.10) or 
less shall:

[[Page 221]]

    (1) Conduct the initial performance test over 24 consecutive steam 
generating unit operating hours at full load;
    (2) Determine compliance with the standards after the initial 
performance test based on the arithmetic average of the hourly emissions 
data during each steam generating unit operating day if a CEMS is used, 
or based on a daily average if Method 6B of appendix A of this part or 
fuel sampling and analysis procedures under Method 19 of appendix A of 
this part are used.
    (e) The owner or operator of an affected facility subject to Sec. 
60.42b(d)(1) shall demonstrate the maximum design capacity of the steam 
generating unit by operating the facility at maximum capacity for 24 
hours. This demonstration will be made during the initial performance 
test and a subsequent demonstration may be requested at any other time. 
If the 24-hour average firing rate for the affected facility is less 
than the maximum design capacity provided by the manufacturer of the 
affected facility, the 24-hour average firing rate shall be used to 
determine the capacity utilization rate for the affected facility, 
otherwise the maximum design capacity provided by the manufacturer is 
used.
    (f) For the initial performance test required under Sec. 60.8, 
compliance with the SO2 emission limits and percent reduction 
requirements under Sec. 60.42b is based on the average emission rates 
and the average percent reduction for SO2 for the first 30 
consecutive steam generating unit operating days, except as provided 
under paragraph (d) of this section. The initial performance test is the 
only test for which at least 30 days prior notice is required unless 
otherwise specified by the Administrator. The initial performance test 
is to be scheduled so that the first steam generating unit operating day 
of the 30 successive steam generating unit operating days is completed 
within 30 days after achieving the maximum production rate at which the 
affected facility will be operated, but not later than 180 days after 
initial startup of the facility. The boiler load during the 30-day 
period does not have to be the maximum design load, but must be 
representative of future operating conditions and include at least one 
24-hour period at full load.
    (g) After the initial performance test required under Sec. 60.8, 
compliance with the SO2 emission limits and percent reduction 
requirements under Sec. 60.42b is based on the average emission rates 
and the average percent reduction for SO2 for 30 successive 
steam generating unit operating days, except as provided under paragraph 
(d). A separate performance test is completed at the end of each steam 
generating unit operating day after the initial performance test, and a 
new 30-day average emission rate and percent reduction for 
SO2 are calculated to show compliance with the standard.
    (h) Except as provided under paragraph (i) of this section, the 
owner or operator of an affected facility shall use all valid 
SO2 emissions data in calculating %Ps and 
Eho under paragraph (c), of this section whether or not the 
minimum emissions data requirements under Sec. 60.46b are achieved. All 
valid emissions data, including valid SO2 emission data 
collected during periods of startup, shutdown and malfunction, shall be 
used in calculating %Ps and Eho pursuant to 
paragraph (c) of this section.
    (i) During periods of malfunction or maintenance of the 
SO2 control systems when oil is combusted as provided under 
Sec. 60.42b(i), emission data are not used to calculate %Ps 
or Es under Sec. 60.42b(a), (b) or (c), however, the 
emissions data are used to determine compliance with the emission limit 
under Sec. 60.42b(i).
    (j) The owner or operator of an affected facility that only combusts 
very low sulfur oil, natural gas, or a mixture of these fuels with any 
other fuels not subject to an SO2 standard is not subject to 
the compliance and performance testing requirements of this section if 
the owner or operator obtains fuel receipts as described in Sec. 
60.49b(r).
    (k) The owner or operator of an affected facility seeking to 
demonstrate compliance in Sec. Sec. 60.42b(d)(4), 60.42b(j), 
60.42b(k)(2), and 60.42b(k)(3) (when not burning coal) shall follow the 
applicable procedures in Sec. 60.49b(r).

Sec. 60.46b  Compliance and performance test methods and procedures
for particulate matter and nitrogen oxides.

    (a) The PM emission standards and opacity limits under Sec. 60.43b 
apply at all times except during periods of startup, shutdown, or 
malfunction. The NOX emission standards under Sec. 60.44b 
apply at all times.
    (b) Compliance with the PM emission standards under Sec. 60.43b 
shall be determined through performance testing as described in 
paragraph (d) of this section, except as provided in paragraph (i) of 
this section.
    (c) Compliance with the NOX emission standards under 
Sec. 60.44b shall be determined through performance testing under 
paragraph (e) or (f), or under paragraphs (g) and (h) of this section, 
as applicable.
    (d) To determine compliance with the PM emission limits and opacity 
limits under Sec. 60.43b, the owner or operator of an affected facility 
shall conduct an initial performance test as required under Sec. 60.8, 
and shall conduct subsequent performance tests as requested by the 
Administrator, using the following procedures and reference methods:
    (1) Method 3A or 3B of appendix A-2 of this part is used for gas 
analysis when applying Method 5 of appendix A-3 of this part or Method 
17 of appendix A-6 of this part.
    (2) Method 5, 5B, or 17 of appendix A of this part shall be used to 
measure the concentration of PM as follows:
    (i) Method 5 of appendix A of this part shall be used at affected 
facilities without wet flue gas desulfurization (FGD) systems; and
    (ii) Method 17 of appendix A-6 of this part may be used at 
facilities with or without wet scrubber systems provided the stack gas 
temperature does not exceed a temperature of 160 [deg]C (320 [deg]F). 
The procedures of sections 8.1 and 11.1 of Method 5B of appendix A-3 of 
this part may be used in Method 17 of appendix A-6 of this part only if 
it is used after a wet FGD system. Do not use Method 17 of appendix A-6 
of this part after wet FGD systems if the effluent is saturated or laden 
with water droplets.
    (iii) Method 5B of appendix A of this part is to be used only after 
wet FGD systems.
    (3) Method 1 of appendix A of this part is used to select the 
sampling site and the number of traverse sampling points. The sampling 
time for each run is at least 120 minutes and the minimum sampling 
volume is 1.7 dscm (60 dscf) except that smaller sampling times or 
volumes may be approved by the Administrator when necessitated by 
process variables or other factors.
    (4) For Method 5 of appendix A of this part, the temperature of the 
sample gas in the probe and filter holder is monitored and is maintained 
at 16014 [deg]C (32025 
[deg]F).
    (5) For determination of PM emissions, the oxygen (O2) or 
CO2 sample is obtained simultaneously with each run of Method 
5, 5B, or 17 of appendix A of this part by traversing the duct at the 
same sampling location.
    (6) For each run using Method 5, 5B, or 17 of appendix A of this 
part, the emission rate expressed in ng/J heat input is determined 
using:
    (i) The O2 or CO2 measurements and PM 
measurements obtained under this section;
    (ii) The dry basis F factor; and
    (iii) The dry basis emission rate calculation procedure contained in 
Method 19 of appendix A of this part.
    (7) Method 9 of appendix A of this part is used for determining the 
opacity of stack emissions.
    (e) To determine compliance with the emission limits for 
NOX required under Sec. 60.44b, the owner or operator of an 
affected facility shall conduct the performance test as required under 
Sec. 60.8 using the continuous system for monitoring NOX 
under Sec. 60.48(b).
    (1) For the initial compliance test, NOX from the steam 
generating unit are monitored for 30 successive steam generating unit 
operating days and the 30-day average emission rate is used to determine 
compliance with the NOX emission standards under Sec. 
60.44b. The 30-day average emission rate is calculated as the average of 
all hourly emissions data recorded by the monitoring system during the 
30-day test period.
    (2) Following the date on which the initial performance test is 
completed

[[Page 223]]

or is required to be completed in Sec. 60.8, whichever date comes 
first, the owner or operator of an affected facility which combusts coal 
(except as specified under Sec. 60.46b(e)(4)) or which combusts 
residual oil having a nitrogen content greater than 0.30 weight percent 
shall determine compliance with the NOX emission standards in 
Sec. 60.44b on a continuous basis through the use of a 30-day rolling 
average emission rate. A new 30-day rolling average emission rate is 
calculated for each steam generating unit operating day as the average 
of all of the hourly NOX emission data for the preceding 30 
steam generating unit operating days.
    (3) Following the date on which the initial performance test is 
completed or is required to be completed under Sec. 60.8, whichever 
date comes first, the owner or operator of an affected facility that has 
a heat input capacity greater than 73 MW (250 MMBtu/hr) and that 
combusts natural gas, distillate oil, or residual oil having a nitrogen 
content of 0.30 weight percent or less shall determine compliance with 
the NOX standards under Sec. 60.44b on a continuous basis 
through the use of a 30-day rolling average emission rate. A new 30-day 
rolling average emission rate is calculated each steam generating unit 
operating day as the average of all of the hourly NOX 
emission data for the preceding 30 steam generating unit operating days.
    (4) Following the date on which the initial performance test is 
completed or required to be completed under Sec. 60.8, whichever date 
comes first, the owner or operator of an affected facility that has a 
heat input capacity of 73 MW (250 MMBtu/hr) or less and that combusts 
natural gas, distillate oil, gasified coal, or residual oil having a 
nitrogen content of 0.30 weight percent or less shall upon request 
determine compliance with the NOX standards in Sec. 60.44b 
through the use of a 30-day performance test. During periods when 
performance tests are not requested, NOX emissions data 
collected pursuant to Sec. 60.48b(g)(1) or Sec. 60.48b(g)(2) are used 
to calculate a 30-day rolling average emission rate on a daily basis and 
used to prepare excess emission reports, but will not be used to 
determine compliance with the NOX emission standards. A new 
30-day rolling average emission rate is calculated each steam generating 
unit operating day as the average of all of the hourly NOX 
emission data for the preceding 30 steam generating unit operating days.
    (5) If the owner or operator of an affected facility that combusts 
residual oil does not sample and analyze the residual oil for nitrogen 
content, as specified in Sec. 60.49b(e), the requirements of Sec. 
60.48b(g)(1) apply and the provisions of Sec. 60.48b(g)(2) are 
inapplicable.
    (f) To determine compliance with the emissions limits for 
NOX required by Sec. 60.44b(a)(4) or Sec. 60.44b(l) for 
duct burners used in combined cycle systems, either of the procedures 
described in paragraph (f)(1) or (2) of this section may be used:
    (1) The owner or operator of an affected facility shall conduct the 
performance test required under Sec. 60.8 as follows:
    (i) The emissions rate (E) of NOX shall be computed using 
Equation 1 in this section:
[GRAPHIC] [TIFF OMITTED] TR13JN07.031

Where:

E = Emissions rate of NOX from the duct burner, ng/J (lb/
          MMBtu) heat input;
Esg = Combined effluent emissions rate, in ng/J (lb/MMBtu) 
          heat input using appropriate F factor as described in Method 
          19 of appendix A of this part;
Hg = Heat input rate to the combustion turbine, in J/hr 
          (MMBtu/hr);
Hb = Heat input rate to the duct burner, in J/hr (MMBtu/hr); 
          and
Eg = Emissions rate from the combustion turbine, in ng/J (lb/
          MMBtu) heat input calculated using appropriate F factor as 
          described in Method 19 of appendix A of this part.

    (ii) Method 7E of appendix A of this part or Method 320 of appendix 
A of part 63 shall be used to determine the NOX 
concentrations. Method 3A or 3B of appendix A of this part shall be used 
to determine O2 concentration.
    (iii) The owner or operator shall identify and demonstrate to the 
Administrator's satisfaction suitable methods to determine the average 
hourly heat input rate to the combustion turbine and the average hourly 
heat input rate to the affected duct burner.

[[Page 224]]

    (iv) Compliance with the emissions limits under Sec. 60.44b(a)(4) 
or Sec. 60.44b(l) is determined by the three-run average (nominal 1-
hour runs) for the initial and subsequent performance tests; or
    (2) The owner or operator of an affected facility may elect to 
determine compliance on a 30-day rolling average basis by using the CEMS 
specified under Sec. 60.48b for measuring NOX and 
O2 and meet the requirements of Sec. 60.48b. The sampling 
site shall be located at the outlet from the steam generating unit. The 
NOX emissions rate at the outlet from the steam generating 
unit shall constitute the NOX emissions rate from the duct 
burner of the combined cycle system.
    (g) The owner or operator of an affected facility described in Sec. 
60.44b(j) or Sec. 60.44b(k) shall demonstrate the maximum heat input 
capacity of the steam generating unit by operating the facility at 
maximum capacity for 24 hours. The owner or operator of an affected 
facility shall determine the maximum heat input capacity using the heat 
loss method or the heat input method described in sections 5 and 7.3 of 
the ASME Power Test Codes 4.1 (incorporated by reference, see Sec. 
60.17). This demonstration of maximum heat input capacity shall be made 
during the initial performance test for affected facilities that meet 
the criteria of Sec. 60.44b(j). It shall be made within 60 days after 
achieving the maximum production rate at which the affected facility 
will be operated, but not later than 180 days after initial start-up of 
each facility, for affected facilities meeting the criteria of Sec. 
60.44b(k). Subsequent demonstrations may be required by the 
Administrator at any other time. If this demonstration indicates that 
the maximum heat input capacity of the affected facility is less than 
that stated by the manufacturer of the affected facility, the maximum 
heat input capacity determined during this demonstration shall be used 
to determine the capacity utilization rate for the affected facility. 
Otherwise, the maximum heat input capacity provided by the manufacturer 
is used.
    (h) The owner or operator of an affected facility described in Sec. 
60.44b(j) that has a heat input capacity greater than 73 MW (250 MMBtu/
hr) shall:
    (1) Conduct an initial performance test as required under Sec. 60.8 
over a minimum of 24 consecutive steam generating unit operating hours 
at maximum heat input capacity to demonstrate compliance with the 
NOX emission standards under Sec. 60.44b using Method 7, 7A, 
or 7E of appendix A of this part, Method 320 of appendix A of part 63 of 
this chapter, or other approved reference methods; and
    (2) Conduct subsequent performance tests once per calendar year or 
every 400 hours of operation (whichever comes first) to demonstrate 
compliance with the NOX emission standards under Sec. 60.44b 
over a minimum of 3 consecutive steam generating unit operating hours at 
maximum heat input capacity using Method 7, 7A, or 7E of appendix A of 
this part, Method 320 of appendix A of part 63, or other approved 
reference methods.
    (i) The owner or operator of an affected facility seeking to 
demonstrate compliance with the PM limit in paragraphs Sec. 
60.43b(a)(4) or Sec. 60.43b(h)(5) shall follow the applicable 
procedures in Sec. 60.49b(r).
    (j) In place of PM testing with Method 5 or 5B of appendix A-3 of 
this part, or Method 17 of appendix A-6 of this part, an owner or 
operator may elect to install, calibrate, maintain, and operate a CEMS 
for monitoring PM emissions discharged to the atmosphere and record the 
output of the system. The owner or operator of an affected facility who 
elects to continuously monitor PM emissions instead of conducting 
performance testing using Method 5 or 5B of appendix A-3 of this part or 
Method 17 of appendix A-6 of this part shall comply with the 
requirements specified in paragraphs (j)(1) through (j)(14) of this 
section.
    (1) Notify the Administrator one month before starting use of the 
system.
    (2) Notify the Administrator one month before stopping use of the 
system.
    (3) The monitor shall be installed, evaluated, and operated in 
accordance with Sec. 60.13 of subpart A of this part.
    (4) The initial performance evaluation shall be completed no later 
than 180 days after the date of initial startup of the affected 
facility, as specified

[[Page 225]]

under Sec. 60.8 of subpart A of this part or within 180 days of 
notification to the Administrator of use of the CEMS if the owner or 
operator was previously determining compliance by Method 5, 5B, or 17 of 
appendix A of this part performance tests, whichever is later.
    (5) The owner or operator of an affected facility shall conduct an 
initial performance test for PM emissions as required under Sec. 60.8 
of subpart A of this part. Compliance with the PM emission limit shall 
be determined by using the CEMS specified in paragraph (j) of this 
section to measure PM and calculating a 24-hour block arithmetic average 
emission concentration using EPA Reference Method 19 of appendix A of 
this part, section 4.1.
    (6) Compliance with the PM emission limit shall be determined based 
on the 24-hour daily (block) average of the hourly arithmetic average 
emission concentrations using CEMS outlet data.
    (7) At a minimum, valid CEMS hourly averages shall be obtained as 
specified in paragraphs (j)(7)(i) of this section for 75 percent of the 
total operating hours per 30-day rolling average.
    (i) At least two data points per hour shall be used to calculate 
each 1-hour arithmetic average.
    (ii) [Reserved]
    (8) The 1-hour arithmetic averages required under paragraph (j)(7) 
of this section shall be expressed in ng/J or lb/MMBtu heat input and 
shall be used to calculate the boiler operating day daily arithmetic 
average emission concentrations. The 1-hour arithmetic averages shall be 
calculated using the data points required under Sec. 60.13(e)(2) of 
subpart A of this part.
    (9) All valid CEMS data shall be used in calculating average 
emission concentrations even if the minimum CEMS data requirements of 
paragraph (j)(7) of this section are not met.
    (10) The CEMS shall be operated according to Performance 
Specification 11 in appendix B of this part.
    (11) During the correlation testing runs of the CEMS required by 
Performance Specification 11 in appendix B of this part, PM and 
O2 (or CO2) data shall be collected concurrently 
(or within a 30-to 60-minute period) by both the continuous emission 
monitors and performance tests conducted using the following test 
methods.
    (i) For PM, Method 5 or 5B of appendix A-3 of this part or Method 17 
of appendix A-6 of this part shall be used; and
    (ii) For O2 (or CO2), Method 3A or 3B of 
appendix A-2 of this part, as applicable shall be used.
    (12) Quarterly accuracy determinations and daily calibration drift 
tests shall be performed in accordance with procedure 2 in appendix F of 
this part. Relative Response Audit's must be performed annually and 
Response Correlation Audits must be performed every 3 years.
    (13) When PM emissions data are not obtained because of CEMS 
breakdowns, repairs, calibration checks, and zero and span adjustments, 
emissions data shall be obtained by using other monitoring systems as 
approved by the Administrator or EPA Reference Method 19 of appendix A 
of this part to provide, as necessary, valid emissions data for a 
minimum of 75 percent of total operating hours per 30-day rolling 
average.
    (14) As of January 1, 2012, and within 90 days after the date of 
completing each performance test, as defined in Sec. 60.8, conducted to 
demonstrate compliance with this subpart, you must submit relative 
accuracy test audit (i.e., reference method) data and performance test 
(i.e., compliance test) data, except opacity data, electronically to 
EPA's Central Data Exchange (CDX) by using the Electronic Reporting Tool 
(ERT) (see http://www.epa.gov/ttn/chief/ert /ert__tool.html/) or other 
compatible electronic spreadsheet. Only data collected using test 
methods compatible with ERT are subject to this requirement to be 
submitted electronically into EPA's WebFIRE database.

Sec. 60.47b  Emission monitoring for sulfur dioxide.

    (a) Except as provided in paragraphs (b) and (f) of this section, 
the owner or operator of an affected facility subject to the 
SO2 standards in Sec. 60.42b shall install, calibrate, 
maintain, and operate

[[Page 226]]

CEMS for measuring SO2 concentrations and either 
O2 or CO2 concentrations and shall record the 
output of the systems. For units complying with the percent reduction 
standard, the SO2 and either O2 or CO2 
concentrations shall both be monitored at the inlet and outlet of the 
SO2 control device. If the owner or operator has installed 
and certified SO2 and O2 or CO2 CEMS 
according to the requirements of Sec. 75.20(c)(1) of this chapter and 
appendix A to part 75 of this chapter, and is continuing to meet the 
ongoing quality assurance requirements of Sec. 75.21 of this chapter 
and appendix B to part 75 of this chapter, those CEMS may be used to 
meet the requirements of this section, provided that:
    (1) When relative accuracy testing is conducted, SO2 
concentration data and CO2 (or O2) data are 
collected simultaneously; and
    (2) In addition to meeting the applicable SO2 and 
CO2 (or O2) relative accuracy specifications in 
Figure 2 of appendix B to part 75 of this chapter, the relative accuracy 
(RA) standard in section 13.2 of Performance Specification 2 in appendix 
B to this part is met when the RA is calculated on a lb/MMBtu basis; and
    (3) The reporting requirements of Sec. 60.49b are met. 
SO2 and CO2 (or O2) data used to meet 
the requirements of Sec. 60.49b shall not include substitute data 
values derived from the missing data procedures in subpart D of part 75 
of this chapter, nor shall the SO2 data have been bias 
adjusted according to the procedures of part 75 of this chapter.
    (b) As an alternative to operating CEMS as required under paragraph 
(a) of this section, an owner or operator may elect to determine the 
average SO2 emissions and percent reduction by:
    (1) Collecting coal or oil samples in an as-fired condition at the 
inlet to the steam generating unit and analyzing them for sulfur and 
heat content according to Method 19 of appendix A of this part. Method 
19 of appendix A of this part provides procedures for converting these 
measurements into the format to be used in calculating the average 
SO2 input rate, or
    (2) Measuring SO2 according to Method 6B of appendix A of 
this part at the inlet or outlet to the SO2 control system. 
An initial stratification test is required to verify the adequacy of the 
sampling location for Method 6B of appendix A of this part. The 
stratification test shall consist of three paired runs of a suitable 
SO2 and CO2 measurement train operated at the 
candidate location and a second similar train operated according to the 
procedures in Section 3.2 and the applicable procedures in Section 7 of 
Performance Specification 2. Method 6B of appendix A of this part, 
Method 6A of appendix A of this part, or a combination of Methods 6 and 
3 or 3B of appendix A of this part or Methods 6C or Method 320 of 
appendix A of part 63 of this chapter and 3A of appendix A of this part 
are suitable measurement techniques. If Method 6B of appendix A of this 
part is used for the second train, sampling time and timer operation may 
be adjusted for the stratification test as long as an adequate sample 
volume is collected; however, both sampling trains are to be operated 
similarly. For the location to be adequate for Method 6B of appendix A 
of this part, 24-hour tests, the mean of the absolute difference between 
the three paired runs must be less than 10 percent.
    (3) A daily SO2 emission rate, ED, shall be 
determined using the procedure described in Method 6A of appendix A of 
this part, section 7.6.2 (Equation 6A-8) and stated in ng/J (lb/MMBtu) 
heat input.
    (4) The mean 30-day emission rate is calculated using the daily 
measured values in ng/J (lb/MMBtu) for 30 successive steam generating 
unit operating days using equation 19-20 of Method 19 of appendix A of 
this part.
    (c) The owner or operator of an affected facility shall obtain 
emission data for at least 75 percent of the operating hours in at least 
22 out of 30 successive boiler operating days. If this minimum data 
requirement is not met with a single monitoring system, the owner or 
operator of the affected facility shall supplement the emission data 
with data collected with other monitoring systems as approved by the 
Administrator or the reference methods

[[Page 227]]

and procedures as described in paragraph (b) of this section.
    (d) The 1-hour average SO2 emission rates measured by the 
CEMS required by paragraph (a) of this section and required under Sec. 
60.13(h) is expressed in ng/J or lb/MMBtu heat input and is used to 
calculate the average emission rates under Sec. 60.42(b). Each 1-hour 
average SO2 emission rate must be based on 30 or more minutes 
of steam generating unit operation. The hourly averages shall be 
calculated according to Sec. 60.13(h)(2). Hourly SO2 
emission rates are not calculated if the affected facility is operated 
less than 30 minutes in a given clock hour and are not counted toward 
determination of a steam generating unit operating day.
    (e) The procedures under Sec. 60.13 shall be followed for 
installation, evaluation, and operation of the CEMS.
    (1) Except as provided for in paragraph (e)(4) of this section, all 
CEMS shall be operated in accordance with the applicable procedures 
under Performance Specifications 1, 2, and 3 of appendix B of this part.
    (2) Except as provided for in paragraph (e)(4) of this section, 
quarterly accuracy determinations and daily calibration drift tests 
shall be performed in accordance with Procedure 1 of appendix F of this 
part.
    (3) For affected facilities combusting coal or oil, alone or in 
combination with other fuels, the span value of the SO2 CEMS 
at the inlet to the SO2 control device is 125 percent of the 
maximum estimated hourly potential SO2 emissions of the fuel 
combusted, and the span value of the CEMS at the outlet to the 
SO2 control device is 50 percent of the maximum estimated 
hourly potential SO2 emissions of the fuel combusted. 
Alternatively, SO2 span values determined according to 
section 2.1.1 in appendix A to part 75 of this chapter may be used.
    (4) As an alternative to meeting the requirements of requirements of 
paragraphs (e)(1) and (e)(2) of this section, the owner or operator may 
elect to implement the following alternative data accuracy assessment 
procedures:
    (i) For all required CO2 and O2 monitors and 
for SO2 and NOX monitors with span values greater 
than or equal to 100 ppm, the daily calibration error test and 
calibration adjustment procedures described in sections 2.1.1 and 2.1.3 
of appendix B to part 75 of this chapter may be followed instead of the 
CD assessment procedures in Procedure 1, section 4.1 of appendix F to 
this part.
    (ii) For all required CO2 and O2 monitors and 
for SO2 and NOX monitors with span values greater 
than 30 ppm, quarterly linearity checks may be performed in accordance 
with section 2.2.1 of appendix B to part 75 of this chapter, instead of 
performing the cylinder gas audits (CGAs) described in Procedure 1, 
section 5.1.2 of appendix F to this part. If this option is selected: 
The frequency of the linearity checks shall be as specified in section 
2.2.1 of appendix B to part 75 of this chapter; the applicable linearity 
specifications in section 3.2 of appendix A to part 75 of this chapter 
shall be met; the data validation and out-of-control criteria in section 
2.2.3 of appendix B to part 75 of this chapter shall be followed instead 
of the excessive audit inaccuracy and out-of-control criteria in 
Procedure 1, section 5.2 of appendix F to this part; and the grace 
period provisions in section 2.2.4 of appendix B to part 75 of this 
chapter shall apply. For the purposes of data validation under this 
subpart, the cylinder gas audits described in Procedure 1, section 5.1.2 
of appendix F to this part shall be performed for SO2 and 
NOX span values less than or equal to 30 ppm; and
    (iii) For SO2, CO2, and O2 
monitoring systems and for NOX emission rate monitoring 
systems, RATAs may be performed in accordance with section 2.3 of 
appendix B to part 75 of this chapter instead of following the 
procedures described in Procedure 1, section 5.1.1 of appendix F to this 
part. If this option is selected: The frequency of each RATA shall be as 
specified in section 2.3.1 of appendix B to part 75 of this chapter; the 
applicable relative accuracy specifications shown in Figure 2 in 
appendix B to part 75 of this chapter shall be met; the data validation 
and out-of-control criteria in section 2.3.2 of appendix B to part 75 of 
this chapter shall be followed instead of the excessive audit inaccuracy 
and out-of-control criteria in Procedure 1, section 5.2 of appendix F to 
this part; and the grace period provisions in section 2.3.3

[[Page 228]]

of appendix B to part 75 of this chapter shall apply. For the purposes 
of data validation under this subpart, the relative accuracy 
specification in section 13.2 of Performance Specification 2 in appendix 
B to this part shall be met on a lb/MMBtu basis for SO2 
(regardless of the SO2 emission level during the RATA), and 
for NOX when the average NOX emission rate 
measured by the reference method during the RATA is less than 0.100 lb/
MMBtu.
    (f) The owner or operator of an affected facility that combusts very 
low sulfur oil or is demonstrating compliance under Sec. 60.45b(k) is 
not subject to the emission monitoring requirements under paragraph (a) 
of this section if the owner or operator maintains fuel records as 
described in Sec. 60.49b(r).

second observations are less than or equal to 20 percent during the 
initial 60 minutes of observation.
    (1) Except as provided in paragraph (a)(2) and (a)(3) of this 
section, the owner or operator shall conduct subsequent Method 9 of 
appendix A-4 of this part performance tests using the procedures in 
paragraph (a) of this section according to the applicable schedule in 
paragraphs (a)(1)(i) through (a)(1)(iv) of this section, as determined 
by the most recent Method 9 of appendix A-4 of this part performance 
test results.
    (i) If no visible emissions are observed, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 12 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later;
    (ii) If visible emissions are observed but the maximum 6-minute 
average opacity is less than or equal to 5 percent, a subsequent Method 
9 of appendix A-4 of this part performance test must be completed within 
6 calendar months from the date that the most recent performance test 
was conducted or within 45 days of the next day that fuel with an 
opacity standard is combusted, whichever is later;

percent but less than or equal to 10 percent, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 3 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later; or
    (iv) If the maximum 6-minute average opacity is greater than 10 
percent, a subsequent Method 9 of appendix A-4 of this part performance 
test must be completed within 45 calendar days from the date that the 
most recent performance test was conducted.
    (2) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 of this part performance tests, elect to 
perform subsequent monitoring using Method 22 of appendix A-

[[Page 229]]

7 of this part according to the procedures specified in paragraphs 
(a)(2)(i) and (ii) of this section.
    (i) The owner or operator shall conduct 10 minute observations 
(during normal operation) each operating day the affected facility fires 
fuel for which an opacity standard is applicable using Method 22 of 
appendix A-7 of this part and demonstrate that the sum of the 
occurrences of any visible emissions is not in excess of 5 percent of 
the observation period (i.e., 30 seconds per 10 minute period). If the 
sum of the occurrence of any visible emissions is greater than 30 
seconds during the initial 10 minute observation, immediately conduct a 
30 minute observation. If the sum of the occurrence of visible emissions 
is greater than 5 percent of the observation period (i.e., 90 seconds 
per 30 minute period), the owner or operator shall either document and 
adjust the operation of the facility and demonstrate within 24 hours 
that the sum of the occurrence of visible emissions is equal to or less 
than 5 percent during a 30 minute observation (i.e., 90 seconds) or

using the procedures in paragraph (a) of this section within 45 calendar 
days according to the requirements in Sec. 60.46d(d)(7).
    (ii) If no visible emissions are observed for 10 operating days 
during which an opacity standard is applicable, observations can be 
reduced to once every 7 operating days during which an opacity standard 
is applicable. If any visible emissions are observed, daily observations 
shall be resumed.
    (3) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 performance tests, elect to perform subsequent 
monitoring using a digital opacity compliance system according to a 
site-specific monitoring plan approved by the Administrator. The 
observations shall be similar, but not necessarily identical, to the 
requirements in paragraph (a)(2) of this section. For reference purposes 
in preparing the monitoring plan, see OAQPS ``Determination of Visible 
Emission Opacity from Stationary Sources Using Computer-Based

that the owner or operator shall also meet the requirements of Sec. 
60.49b. Data reported to meet the requirements of Sec. 60.49b shall not 
include data substituted using the missing data procedures in subpart D 
of part 75 of this chapter, nor shall the data have been bias adjusted 
according to the procedures of part 75 of this chapter.
    (c) The CEMS required under paragraph (b) of this section shall be 
operated and data recorded during all periods of operation of the 
affected facility except for CEMS breakdowns and repairs. Data is 
recorded during calibration checks, and zero and span adjustments.
    (d) The 1-hour average NOX emission rates measured by the 
continuous NOX monitor required by paragraph (b) of this 
section and required under Sec. 60.13(h) shall be expressed in ng/J or

maintained at levels less than or equal to 0.15 lb/MMBtu on a steam 
generating unit operating day average basis. Owners and operators of 
affected facilities electing to comply with this paragraph must 
demonstrate compliance according to the procedures specified in 
paragraphs (j)(4)(i) through (iv) of this section; or
    (i) You must monitor CO emissions using a CEMS according to the

of this part.
    (B) Each 1-hour CO emissions average is calculated using the data 
points generated by the CO CEMS expressed in parts per million by volume 
corrected to 3 percent oxygen (dry basis).
    (C) At a minimum, valid 1-hour CO emissions averages must be 
obtained for at least 90 percent of the operating hours on a 30-day

criteria for establishing and monitoring specific parameters for the 
affected facility indicative of compliance with the opacity standard.
    (k) Owners or operators complying with the PM emission limit by 
using a PM CEMS must calibrate, maintain, operate, and record the output 
of the system for PM emissions discharged to the atmosphere as specified 
in Sec. 60.46b(j). The CEMS specified in paragraph Sec. 60.46b(j) 
shall be operated and data recorded during all periods of operation of 
the affected facility except for CEMS breakdowns and repairs. Data is

reduction) when combusting coal, oil, wood, a mixture of these fuels, or 
a mixture of these fuels with any other fuels.
    (3) On and after the date on which the initial performance test is 
completed or is required to be completed under Sec. 60.8, whichever 
date comes first, no owner or operator of an affected facility that 
commences modification after February 28, 2005, and that combusts over 
30 percent wood (by heat input) on an annual basis and has a heat input 
capacity of 8.7 MW (30 MMBtu/h) or greater shall cause to be discharged 
into the atmosphere from that affected facility any gases that contain 
PM in excess of 43 ng/J (0.10 lb/MMBtu) heat input.
    (4) An owner or operator of an affected facility that commences 
construction, reconstruction, or modification after February 28, 2005, 
and that combusts only oil that contains no more than 0.50 weight 
percent sulfur or a mixture of 0.50 weight percent sulfur oil with other

Sec. 60.44c  Compliance and performance test methods and procedures for sulfur dioxide.

    (a) Except as provided in paragraphs (g) and (h) of this section and 
Sec. 60.8(b), performance tests required under Sec. 60.8 shall be 
conducted following the procedures specified in paragraphs (b), (c), 
(d), (e), and (f) of this section, as applicable. Section 60.8(f) does 
not apply to this section. The 30-day notice required in Sec. 60.8(d) 
applies only to the initial performance test unless otherwise specified 
by the Administrator.
    (b) The initial performance test required under Sec. 60.8 shall be 
conducted over 30 consecutive operating days of the steam generating 
unit. Compliance with the percent reduction requirements and 
SO2 emission limits under Sec. 60.42c shall be determined 
using a 30-day average. The first operating day included in the initial 
performance test shall be scheduled within 30 days after achieving the 
maximum production rate at which the affect facility will be operated, 
but not later than 180 days after the initial startup of the facility. 
The steam generating unit load during the 30-day period does not have to 
be the maximum design heat input capacity, but must be representative of 
future operating conditions.
    (c) After the initial performance test required under paragraph (b) 
of this section and Sec. 60.8, compliance with the percent reduction 
requirements and SO2 emission limits under Sec. 60.42c is 
based on the average percent reduction and the average SO2 
emission rates for 30 consecutive steam generating unit operating days. 
A separate performance test is completed at the end of each steam 
generating unit operating day, and a new 30-day average percent 
reduction and SO2 emission rate are calculated to show 
compliance with the standard.
    (d) If only coal, only oil, or a mixture of coal and oil is 
combusted in an affected facility, the procedures in Method 19 of 
appendix A of this part are used to determine the hourly SO2 
emission rate (Eho) and the 30-day average SO2 
emission rate (Eao). The hourly averages used to compute the 
30-day averages are obtained from the CEMS. Method 19 of appendix A of 
this part shall be used to calculate Eao when using daily 
fuel sampling or Method 6B of appendix A of this part.
    (e) If coal, oil, or coal and oil are combusted with other fuels:

[[Page 247]]

    (1) An adjusted Eho (Ehoo) is used in Equation 
19-19 of Method 19 of appendix A of this part to compute the adjusted 
Eao (Eaoo). The Ehoo is computed using 
the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.033

Where:

Ehoo = Adjusted Eho, ng/J (lb/MMBtu);
Eho = Hourly SO2 emission rate, ng/J (lb/MMBtu);
Ew = SO2 concentration in fuels other than coal 
          and oil combusted in the affected facility, as determined by 
          fuel sampling and analysis procedures in Method 9 of appendix 
          A of this part, ng/J (lb/MMBtu). The value Ew for 
          each fuel lot is used for each hourly average during the time 
          that the lot is being combusted. The owner or operator does 
          not have to measure Ew if the owner or operator 
          elects to assume Ew = 0.
Xk = Fraction of the total heat input from fuel combustion 
          derived from coal and oil, as determined by applicable 
          procedures in Method 19 of appendix A of this part.

    (2) The owner or operator of an affected facility that qualifies 
under the provisions of Sec. 60.42c(c) or (d) (where percent reduction 
is not required) does not have to measure the parameters Ew 
or Xk if the owner or operator of the affected facility 
elects to measure emission rates of the coal or oil using the fuel 
sampling and analysis procedures under Method 19 of appendix A of this 
part.
    (f) Affected facilities subject to the percent reduction 
requirements under Sec. 60.42c(a) or (b) shall determine compliance 
with the SO2 emission limits under Sec. 60.42c pursuant to 
paragraphs (d) or (e) of this section, and shall determine compliance 
with the percent reduction requirements using the following procedures:
    (1) If only coal is combusted, the percent of potential 
SO2 emission rate is computed using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.034

Where:

%Ps = Potential SO2 emission rate, in percent;
%Rg = SO2 removal efficiency of the control device 
          as determined by Method 19 of appendix A of this part, in 
          percent; and
%Rf = SO2 removal efficiency of fuel pretreatment 
          as determined by Method 19 of appendix A of this part, in 
          percent.

    (2) If coal, oil, or coal and oil are combusted with other fuels, 
the same procedures required in paragraph (f)(1) of this section are 
used, except as provided for in the following:
    (i) To compute the %Ps, an adjusted %Rg 
(%Rgo) is computed from Eaoo from paragraph (e)(1) 
of this section and an adjusted average SO2 inlet rate 
(Eaio) using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.035

Where:

%Rgo = Adjusted %Rg, in percent;
Eaoo = Adjusted Eao, ng/J (lb/MMBtu); and
Eaio = Adjusted average SO2 inlet rate, ng/J (lb/
          MMBtu).

    (ii) To compute Eaio, an adjusted hourly SO2 
inlet rate (Ehio) is used. The Ehio is computed 
using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.036

Where:

Ehio = Adjusted Ehi, ng/J (lb/MMBtu);
Ehi = Hourly SO2 inlet rate, ng/J (lb/MMBtu);
Ew = SO2 concentration in fuels other than coal 
          and oil combusted in the affected facility, as determined by 
          fuel sampling and analysis procedures in Method 19 of appendix 
          A of this part, ng/J (lb/MMBtu). The value Ew for 
          each fuel lot is used for each hourly average during the time 
          that the lot is being combusted. The owner or operator does 
          not have to measure Ew if the owner or operator 
          elects to assume Ew = 0; and
Xk = Fraction of the total heat input from fuel combustion 
          derived from coal and oil, as determined by applicable 
          procedures in Method 19 of appendix A of this part.

    (g) For oil-fired affected facilities where the owner or operator 
seeks to demonstrate compliance with the fuel oil sulfur limits under 
Sec. 60.42c based on shipment fuel sampling, the initial performance 
test shall consist of sampling and analyzing the oil in the initial

[[Page 248]]

tank of oil to be fired in the steam generating unit to demonstrate that 
the oil contains 0.5 weight percent sulfur or less. Thereafter, the 
owner or operator of the affected facility shall sample the oil in the 
fuel tank after each new shipment of oil is received, as described under 
Sec. 60.46c(d)(2).
    (h) For affected facilities subject to Sec. 60.42c(h)(1), (2), or 
(3) where the owner or operator seeks to demonstrate compliance with the 
SO2 standards based on fuel supplier certification, the 
performance test shall consist of the certification from the fuel 
supplier, as described in Sec. 60.48c(f), as applicable.
    (i) The owner or operator of an affected facility seeking to 
demonstrate compliance with the SO2 standards under Sec. 
60.42c(c)(2) shall demonstrate the maximum design heat input capacity of 
the steam generating unit by operating the steam generating unit at this 
capacity for 24 hours. This demonstration shall be made during the 
initial performance test, and a subsequent demonstration may be 
requested at any other time. If the demonstrated 24-hour average firing 
rate for the affected facility is less than the maximum design heat 
input capacity stated by the manufacturer of the affected facility, the 
demonstrated 24-hour average firing rate shall be used to determine the 
annual capacity factor for the affected facility; otherwise, the maximum 
design heat input capacity provided by the manufacturer shall be used.
    (j) The owner or operator of an affected facility shall use all 
valid SO2 emissions data in calculating %Ps and 
Eho under paragraphs (d), (e), or (f) of this section, as 
applicable, whether or not the minimum emissions data requirements under 
Sec. 60.46c(f) are achieved. All valid emissions data, including valid 
data collected during periods of startup, shutdown, and malfunction, 
shall be used in calculating %Ps or Eho pursuant 
to paragraphs (d), (e), or (f) of this section, as applicable.

    (c) In place of PM testing with Method 5 or 5B of appendix A-3 of 
this part or Method 17 of appendix A-6 of this part, an owner or 
operator may elect to install, calibrate, maintain, and operate a CEMS 
for monitoring PM emissions discharged to the atmosphere and record the 
output of the system. The owner or operator of an affected facility who 
elects to continuously monitor PM emissions instead of conducting 
performance testing using Method 5 or 5B of appendix A-3 of this part or 
Method 17 of appendix A-6 of this part shall install, calibrate, 
maintain, and operate a CEMS and shall comply with the requirements 
specified in paragraphs (c)(1) through (c)(14) of this section.
    (1) Notify the Administrator 1 month before starting use of the 
system.

Sec. 60.46c  Emission monitoring for sulfur dioxide.

    (a) Except as provided in paragraphs (d) and (e) of this section, 
the owner or operator of an affected facility subject to the 
SO2 emission limits under Sec. 60.42c shall install, 
calibrate, maintain, and operate a CEMS for measuring SO2 
concentrations and either O2 or CO2 concentrations 
at the outlet of the SO2 control device (or the outlet of the 
steam generating unit if no SO2 control device is used), and 
shall record the output of the system. The owner or operator of an 
affected facility subject to the percent reduction requirements under 
Sec. 60.42c shall measure SO2 concentrations and either 
O2 or CO2 concentrations at both the inlet and 
outlet of the SO2 control device.
    (b) The 1-hour average SO2 emission rates measured by a 
CEMS shall be expressed in ng/J or lb/MMBtu heat input and shall be used 
to calculate the average emission rates under Sec. 60.42c. Each 1-hour 
average SO2 emission rate must be based on at least 30 
minutes of operation, and shall be calculated using the data points 
required under Sec. 60.13(h)(2). Hourly SO2 emission rates 
are not calculated if the affected facility is operated less than 30 
minutes in a 1-hour period and are not counted toward determination of a 
steam generating unit operating day.
    (c) The procedures under Sec. 60.13 shall be followed for 
installation, evaluation, and operation of the CEMS.

[[Page 251]]

    (1) All CEMS shall be operated in accordance with the applicable 
procedures under Performance Specifications 1, 2, and 3 of appendix B of 
this part.
    (2) Quarterly accuracy determinations and daily calibration drift 
tests shall be performed in accordance with Procedure 1 of appendix F of 
this part.
    (3) For affected facilities subject to the percent reduction 
requirements under Sec. 60.42c, the span value of the SO2 
CEMS at the inlet to the SO2 control device shall be 125 
percent of the maximum estimated hourly potential SO2 
emission rate of the fuel combusted, and the span value of the 
SO2 CEMS at the outlet from the SO2 control device 
shall be 50 percent of the maximum estimated hourly potential 
SO2 emission rate of the fuel combusted.
    (4) For affected facilities that are not subject to the percent 
reduction requirements of Sec. 60.42c, the span value of the 
SO2 CEMS at the outlet from the SO2 control device 
(or outlet of the steam generating unit if no SO2 control 
device is used) shall be 125 percent of the maximum estimated hourly 
potential SO2 emission rate of the fuel combusted.
    (d) As an alternative to operating a CEMS at the inlet to the 
SO2 control device (or outlet of the steam generating unit if 
no SO2 control device is used) as required under paragraph 
(a) of this section, an owner or operator may elect to determine the 
average SO2 emission rate by sampling the fuel prior to 
combustion. As an alternative to operating a CEMS at the outlet from the 
SO2 control device (or outlet of the steam generating unit if 
no SO2 control device is used) as required under paragraph 
(a) of this section, an owner or operator may elect to determine the 
average SO2 emission rate by using Method 6B of appendix A of 
this part. Fuel sampling shall be conducted pursuant to either paragraph 
(d)(1) or (d)(2) of this section. Method 6B of appendix A of this part 
shall be conducted pursuant to paragraph (d)(3) of this section.
    (1) For affected facilities combusting coal or oil, coal or oil 
samples shall be collected daily in an as-fired condition at the inlet 
to the steam generating unit and analyzed for sulfur content and heat 
content according the Method 19 of appendix A of this part. Method 19 of 
appendix A of this part provides procedures for converting these 
measurements into the format to be used in calculating the average 
SO2 input rate.
    (2) As an alternative fuel sampling procedure for affected 
facilities combusting oil, oil samples may be collected from the fuel 
tank for each steam generating unit immediately after the fuel tank is 
filled and before any oil is combusted. The owner or operator of the 
affected facility shall analyze the oil sample to determine the sulfur 
content of the oil. If a partially empty fuel tank is refilled, a new 
sample and analysis of the fuel in the tank would be required upon 
filling. Results of the fuel analysis taken after each new shipment of 
oil is received shall be used as the daily value when calculating the 
30-day rolling average until the next shipment is received. If the fuel 
analysis shows that the sulfur content in the fuel tank is greater than 
0.5 weight percent sulfur, the owner or operator shall ensure that the 
sulfur content of subsequent oil shipments is low enough to cause the 
30-day rolling average sulfur content to be 0.5 weight percent sulfur or 
less.
    (3) Method 6B of appendix A of this part may be used in lieu of CEMS 
to measure SO2 at the inlet or outlet of the SO2 
control system. An initial stratification test is required to verify the 
adequacy of the Method 6B of appendix A of this part sampling location. 
The stratification test shall consist of three paired runs of a suitable 
SO2 and CO2 measurement train operated at the 
candidate location and a second similar train operated according to the 
procedures in Sec. 3.2 and the applicable procedures in section 7 of 
Performance Specification 2 of appendix B of this part. Method 6B of 
appendix A of this part, Method 6A of appendix A of this part, or a 
combination of Methods 6 and 3 of appendix A of this part or Methods 6C 
and 3A of appendix A of this part are suitable measurement techniques. 
If Method 6B of appendix A of this part is used for the second train, 
sampling time and timer operation may be adjusted for the

[[Page 252]]

stratification test as long as an adequate sample volume is collected; 
however, both sampling trains are to be operated similarly. For the 
location to be adequate for Method 6B of appendix A of this part 24-hour 
tests, the mean of the absolute difference between the three paired runs 
must be less than 10 percent (0.10).
    (e) The monitoring requirements of paragraphs (a) and (d) of this 
section shall not apply to affected facilities subject to Sec. 
60.42c(h) (1), (2), or (3) where the owner or operator of the affected 
facility seeks to demonstrate compliance with the SO2 
standards based on fuel supplier certification, as described under Sec. 
60.48c(f), as applicable.
    (f) The owner or operator of an affected facility operating a CEMS 
pursuant to paragraph (a) of this section, or conducting as-fired fuel 
sampling pursuant to paragraph (d)(1) of this section, shall obtain 
emission data for at least 75 percent of the operating hours in at least 
22 out of 30 successive steam generating unit operating days. If this 
minimum data requirement is not met with a single monitoring system, the 
owner or operator of the affected facility shall supplement the emission 
data with data collected with other monitoring systems as approved by 
the Administrator.



Sec. 60.47c  Emission monitoring for particulate matter.

    (a) Except as provided in paragraphs (c), (d), (e), and (f) of this 
section, the owner or operator of an affected facility combusting coal, 
oil, or wood that is subject to the opacity standards under Sec. 60.43c 
shall install, calibrate, maintain, and operate a continuous opacity 
monitoring system (COMS) for measuring the opacity of the emissions 
discharged to the atmosphere and record the output of the system. The 
owner or operator of an affected facility subject to an opacity standard 
in Sec. 60.43c(c) that is not required to use a COMS due to paragraphs 
(c), (d), (e), or (f) of this section that elects not to use a COMS 
shall conduct a performance test using Method 9 of appendix A-4 of this 
part and the procedures in Sec. 60.11 to demonstrate compliance with 
the applicable limit in Sec. 60.43c by April 29, 2011, within 45 days 
of stopping use of an existing COMS, or within 180 days after initial 
startup of the facility, whichever is later, and shall comply with

observation period for Method 9 of appendix A-4 of this part performance 
tests may be reduced from 3 hours to 60 minutes if all 6-minute averages 
are less than 10 percent and all individual 15-second observations are 
less than or equal to 20 percent during the initial 60 minutes of 
observation.
    (1) Except as provided in paragraph (a)(2) and (a)(3) of this 
section, the owner or operator shall conduct subsequent Method 9 of 
appendix A-4 of this part performance tests using the procedures in 
paragraph (a) of this section according to the applicable schedule in 
paragraphs (a)(1)(i) through (a)(1)(iv) of this section, as determined 
by the most recent Method 9 of appendix A-4 of this part performance 
test results.
    (i) If no visible emissions are observed, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 12 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later;
    (ii) If visible emissions are observed but the maximum 6-minute 
average opacity is less than or equal to 5 percent, a subsequent Method 
9 of appendix A-4 of this part performance test must be completed within 
6 calendar months from the date that the most recent performance test 
was conducted or within 45 days of the next day that fuel with an 
opacity standard is combusted, whichever is later;
    (iii) If the maximum 6-minute average opacity is greater than 5 
percent but less than or equal to 10 percent, a subsequent Method 9 of 
appendix A-4 of this part performance test must be completed within 3 
calendar months from the date that the most recent performance test was 
conducted or within 45 days of the next day that fuel with an opacity 
standard is combusted, whichever is later; or

the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 of this part performance tests, elect to 
perform subsequent monitoring using Method 22 of appendix A-7 of this 
part according to the procedures specified in paragraphs (a)(2)(i) and 
(ii) of this section.
    (i) The owner or operator shall conduct 10 minute observations 
(during normal operation) each operating day the affected facility fires 
fuel for which an opacity standard is applicable using Method 22 of 
appendix A-7 of this part and demonstrate that the sum of the 
occurrences of any visible emissions is not in excess of 5 percent of 
the observation period (i.e. , 30 seconds per 10 minute period). If the 
sum of the occurrence of any visible emissions is greater than 30 
seconds during the initial 10 minute observation, immediately conduct a 
30 minute observation. If the sum of the occurrence of visible emissions 
is greater than 5 percent of the observation period (i.e., 90 seconds 
per 30 minute period), the owner or operator shall either document and 
adjust the operation of the facility and demonstrate within 24 hours 
that the sum of the occurrence of visible emissions is equal to or less 
than 5 percent during a 30 minute observation (i.e., 90 seconds) or 
conduct a new Method 9 of appendix A-4 of this part performance test 
using the procedures in paragraph (a) of this section within 45 calendar 
days according to the requirements in Sec. 60.45c(a)(8).
    (ii) If no visible emissions are observed for 10 operating days 
during which an opacity standard is applicable, observations can be 
reduced to once every 7 operating days during which an opacity standard 
is applicable. If any visible emissions are observed, daily observations 
shall be resumed.
    (3) If the maximum 6-minute opacity is less than 10 percent during 
the most recent Method 9 of appendix A-4 of this part performance test, 
the owner or operator may, as an alternative to performing subsequent 
Method 9 of appendix A-4 performance tests, elect to perform subsequent 
monitoring using a digital opacity compliance system according to a 
site-specific monitoring plan approved by the Administrator. The 
observations shall be similar, but not necessarily identical, to the 
requirements in paragraph (a)(2) of this section. For reference purposes 
in preparing the monitoring plan, see OAQPS ``Determination of Visible 
Emission Opacity from Stationary Sources Using Computer-Based 
Photographic Analysis Systems.'' This document is available from the 
U.S. Environmental Protection Agency (U.S. EPA); Office of Air Quality 
and Planning Standards; Sector Policies and Programs Division; 
Measurement Policy Group (D243-02), Research Triangle Park, NC 27711. 
This document is also available on the Technology Transfer Network (TTN)

post-combustion technology to reduce SO2 or PM emissions and that are 
subject to an opacity standard in Sec. 60.43c(c) are not required to 
operate a COMS if they follow the applicable procedures in Sec. 
60.48c(f).
    (d) Owners or operators complying with the PM emission limit by 
using a PM CEMS must calibrate, maintain, operate, and record the output 
of the system for PM emissions discharged to the atmosphere as specified 
in Sec. 60.45c(c). The CEMS specified in paragraph Sec. 60.45c(c) 
shall be operated and data recorded during all periods of operation of 
the affected facility except for CEMS breakdowns and repairs. Data is 
recorded during calibration checks, and zero and span adjustments.

an opacity standard in Sec. 60.43c(c) and that does not use post-
combustion technology (except a wet scrubber) for reducing PM, 
SO2, or carbon monoxide (CO) emissions, burns only gaseous 
fuels or fuel oils that contain less than or equal to 0.5 weight percent 
sulfur, and is operated such that emissions of CO discharged to the 
atmosphere from the affected facility are maintained at levels less than 
or equal to 0.15 lb/MMBtu on a boiler operating day average basis is not 
required to operate a COMS. Owners and operators of affected facilities 
electing to comply with this paragraph must demonstrate compliance 
according to the procedures specified in paragraphs (e)(1) through (4)

of this part.
    (ii) Each 1-hour CO emissions average is calculated using the data 
points generated by the CO CEMS expressed in parts per million by volume 
corrected to 3 percent oxygen (dry basis).
    (iii) At a minimum, valid 1-hour CO emissions averages must be 
obtained for at least 90 percent of the operating hours on a 30-day 
rolling average basis. The 1-hour averages are calculated using the data 
points required in Sec. 60.13(h)(2).
    (iv) Quarterly accuracy determinations and daily calibration drift 
tests for the CO CEMS must be performed in accordance with procedure 1 
in appendix F of this part.
    (2) You must calculate the 1-hour average CO emissions levels for

hourly CO output concentration measured by the CO CEMS times the 
corresponding average hourly flue gas flow rate and divided by the 
corresponding average hourly heat input to the affected source. The 24-
hour average CO emission level is determined by calculating the 
arithmetic average of the hourly CO emission levels computed for each 
steam generating unit operating day.
    (3) You must evaluate the preceding 24-hour average CO emission 
level each steam generating unit operating day excluding periods of 
affected source startup, shutdown, or malfunction. If the 24-hour 
average CO emission level is greater than 0.15 lb/MMBtu, you must 
initiate investigation of the relevant equipment and control systems 
within 24 hours of the first discovery of the high emission incident 
and, take the appropriate corrective action as soon as practicable to 
adjust control settings or repair equipment to reduce the 24-hour 
average CO emission level to 0.15 lb/MMBtu or less.
    (4) You must record the CO measurements and calculations performed 
according to paragraph (e) of this section and any corrective actions 
taken. The record of corrective action taken must include the date and 
time during which the 24-hour average CO emission level was greater than 
0.15 lb/MMBtu, and the date, time, and description of the corrective 
action.

an opacity standard in Sec. 60.43c(c) is not required to operate a COMS 
provided that the affected facility meets the conditions in either 
paragraphs (f)(1), (2), or (3) of this section.
    (1) The affected facility uses a fabric filter (baghouse) as the 
primary PM control device and, the owner or operator operates a bag leak 
detection system to monitor the performance of the fabric filter 
according to the requirements in section Sec. 60.48Da of this part.
    (2) The affected facility uses an ESP as the primary PM control 
device, and the owner or operator uses an ESP predictive model to 
monitor the performance of the ESP developed in accordance and operated 
according to the requirements in section Sec. 60.48Da of this part.
    (3) The affected facility burns only gaseous fuels and/or fuel oils 
that contain no greater than 0.5 weight percent sulfur, and the owner or 
operator operates the unit according to a written site-specific 
monitoring plan approved by the permitting authority. This monitoring 
plan must include procedures

[[Page 255]]

and criteria for establishing and monitoring specific parameters for the 
affected facility indicative of compliance with the opacity standard. 
For testing performed as part of this site-specific monitoring plan, the 
permitting authority may require as an alternative to the notification 
and reporting requirements specified in Sec. Sec. 60.8 and 60.11 that 
the owner or operator submit any deviations with the excess emissions 
report required under Sec. 60.48c(c).

[39 FR 20792, June 14, 1974, as amended at 65 FR 61753, Oct. 17, 2000]



Sec. 60.53  Monitoring of operations.

    (a) The owner or operator of any incinerator subject to the 
provisions of this part shall record the daily charging rates and hours 
of operation.



Sec. 60.54  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter standard in Sec. 60.52 as follows:
    (1) The concentration (c12) of particulate matter, 
corrected to 12 percent CO2, shall be computed for each run 
using the following equation:

c12 = cs (12/%CO2)

where:

c12 = concentration of particulate matter, corrected to 12 
          percent CO2, g/dscm (gr/dscf).
cs = concentration of particulate matter, g/dscm (gr/dscf).
%CO2 = CO2 concentration, percent dry basis.

    (2) Method 5 shall be used to determine the particulate matter 
concentration (cs). The sampling time and sample volume for 
each run shall be at least 60 minutes and 0.85 dscm (30 dscf).
    (3) The emission rate correction factor, integrated or grab sampling 
and analysis procedure of Method 3B shall be used to determine 
CO2 concentration (%CO2).
    (i) The CO2 sample shall be obtained simultaneously with, 
and at the same traverse points as, the particulate run. If the 
particulate run has more than 12 traverse points, the CO2 
traverse points may be reduced to 12 if Method 1 is used to locate the 
12 CO2 traverse points. If individual CO2 samples 
are taken at each traverse point, the CO2 concentration 
(%CO2) used in the correction equation shall be the 
arithmetic mean of the sample CO2 concentrations at all 
traverse points.
    (ii) If sampling is conducted after a wet scrubber, an ``adjusted'' 
CO2 concentration [(%CO2)adj], which 
accounts for the effects of CO2 absorption and dilution air, 
may be used instead of the CO2 concentration determined in 
this paragraph. The adjusted CO2 concentration shall be 
determined by either of the procedures in paragraph (c) of this section.
    (c) The owner or operator may use either of the following procedures 
to determine the adjusted CO2 concentration.
    (1) The volumetric flow rates at the inlet and outlet of the wet 
scrubber and the inlet CO2 concentration may be used to 
determine the adjusted CO2

[[Page 259]]

concentration [(%CO2)adj] using the following 
equation:

(%CO2)adj = (%CO2)di 
(Qdi/Qdo)

where:

(%CO2)adj = adjusted outlet CO2 
          concentration, percent dry basis.
(%CO2)di = CO2 concentration measured 
          before the scrubber, percent dry basis.
Qdi = volumetric flow rate of effluent gas before the wet 
          scrubber, dscm/min (dscf/min).
Qdo = volumetric flow rate of effluent gas after the wet 
          scrubber, dscm/min (dscf/min).

    (i) At the outlet, Method 5 is used to determine the volumetric flow 
rate (Qdo) of the effluent gas.
    (ii) At the inlet, Method 2 is used to determine the volumetric flow 
rate (Qdi) of the effluent gas as follows: Two full velocity 
traverses are conducted, one immediately before and one immediately 
after each particulate run conducted at the outlet, and the results are 
averaged.
    (iii) At the inlet, the emission rate correction factor, integrated 
sampling and analysis procedure of Method 3B is used to determine the 
CO2 concentration [(%CO2)di] as 
follows: At least nine sampling points are selected randomly from the 
velocity traverse points and are divided randomly into three sets, equal 
in number of points; the first set of three or more points is used for 
the first run, the second set for the second run, and the third set for 
the third run. The CO2 sample is taken simultaneously with 
each particulate run being conducted at the outlet, by traversing the 
three sampling points (or more) and sampling at each point for equal 
increments of time.
    (2) Excess air measurements may be used to determine the adjusted 
CO2 concentration [(%CO2)adj] using the 
following equation:

(%CO2)adj = (%CO2)di [(100 + 
%EAi)/(100 + %EAo)]

where:

(%CO2)adj = adjusted outlet CO2

away, the owner or operator of the affected facility must meet one of 
three criteria:
    (i) When the certified chief facility operator and certified shift 
supervisor are both off site for 12 hours or less, and no other 
certified operator is on site, the provisionally certified control room 
operator may perform the duties of the certified chief facility operator 
or certified shift supervisor.
    (ii) When the certified chief facility operator and certified shift 
supervisor are off site for more than 12 hours, but for two weeks or 
less, and no other certified operator is on site, the provisionally 
certified control room operator may perform the duties of the certified 
chief facility operator or certified shift supervisor without notice to, 
or approval by, the Administrator. However, the owner or operator of the 
affected facility must record the period when the certified chief 
facility operator and certified shift supervisor are off site and 
include that information in the annual report as specified under Sec. 
60.59b(g)(5).
    (iii) When the certified chief facility operator and certified shift 
supervisor are off site for more than two weeks, and no other certified 
operator is on site, the provisionally certified control room operator 
may perform the duties of the certified chief facility operator or

However, the owner or operator of the affected facility must take two 
actions:
    (A) Notify the Administrator in writing. In the notice, state what 
caused the absence and what actions are being taken by the owner or 
operator of the facility to ensure that a certified chief facility 
operator or certified shift supervisor is on site as expeditiously as 
practicable.
    (B) Submit a status report and corrective action summary to the 
Administrator every four weeks following the initial notification. If 
the Administrator provides notice that the status report or corrective 
action summary is disapproved, the municipal waste combustion unit may 
continue operation for 90 days, but then must cease operation. If 
corrective actions are taken in the 90-day period such that the 
Administrator withdraws the disapproval, municipal waste combustion unit 
operation may continue.
    (3) A provisionally certified operator who is newly promoted or 
recently transferred to a shift supervisor position or a chief facility 
operator position at the municipal waste combustion unit may perform the 
duties of the certified chief facility operator or certified shift 
supervisor without notice to, or approval by, the Administrator for up

feeding of municipal solid waste for purposes of waste disposal, energy 
production, or providing heat to the combustion system in preparation 
for waste disposal or energy production. The use of municipal solid 
waste solely to provide thermal protection of the grate or hearth during 
the startup period when municipal solid waste is not being fed to the 
grate is not considered to be continuous burning.
    (iii) For the purpose of compliance with the carbon monoxide 
emission limits in Sec. 60.53b(a), if a loss of boiler water level 
control (e.g., boiler waterwall tube failure) or a loss of combustion 
air control (e.g., loss of combustion air fan, induced draft fan, 
combustion grate bar failure) is determined to be a malfunction, the 
duration of the malfunction period is limited to 15 hours per 
occurrence. During such periods of malfunction, monitoring data shall be 
dismissed or excluded from compliance calculations, but shall be 
recorded and reported in accordance with the provisions of Sec. 
60.59b(d)(7).

follow the performance testing schedule specified in paragraph 
(g)(5)(iii) of this section and apply the carbon injection system 
operating parameters to similarly designed and equipped units on site 
shall follow the procedures specified in Sec. 60.59b(g)(4) for 
reporting.
    (iii) Where all performance tests over a 2-year period indicate that 
dioxin/furan emissions are less than or equal to 7 nanograms per dry 
standard cubic meter (total mass) for all affected facilities located 
within a municipal waste combustor plant, the owner or operator of the 
municipal waste combustor plant may elect to conduct annual performance 
tests for one affected facility (i.e., unit) per year at the municipal 
waste combustor plant. At a minimum, a performance test for dioxin/furan 
emissions shall be conducted on a calendar year basis (no less than 9 
calendar months and no more than 15 months following the previous 
performance test; and must complete five performance tests in each 5-

combustor plant. Each year a different affected facility at the 
municipal waste combustor plant shall be tested, and the affected 
facilities at the plant shall be tested in sequence (e.g., unit 1, unit 
2, unit 3, as applicable). If each annual performance test continues to 
indicate a dioxin/furan emission level less than or equal to 7 nanograms 
per dry standard cubic meter (total mass), the owner or operator may 
continue conducting a performance test on only one affected facility per 
calendar year. If any annual performance test indicates either a dioxin/
furan emission level greater than 7 nanograms per dry standard cubic 
meter (total mass), performance tests shall thereafter be conducted 
annually on all affected facilities at the plant until and unless all 
annual performance tests for all affected facilities at the plant over a 
2-year period indicate a dioxin/furan emission level less than or equal 
to 7 nanograms per dry standard cubic meter (total mass).

the affected facility shall be established as specified in paragraph 
(b)(6) of this section.
    (9) As specified under Sec. 60.8 of subpart A of this part, all 
performance tests shall consist of three test runs. The average of the 
dioxin/furan emission concentrations from the three test runs is used to 
determine compliance.
    (10) In place of dioxin/furan sampling and testing with EPA 
Reference Method 23, an owner or operator may elect to sample dioxin/
furan by installing,

[[Page 297]]

calibrating, maintaining, and operating a continuous automated sampling 
system for monitoring dioxin/furan emissions discharged to the 
atmosphere, recording the output of the system, and analyzing the sample 
using EPA Method 23. This option to use a continuous automated sampling 
system takes effect on the date a final performance specification 
applicable to dioxin/furan from monitors is published in the Federal 
Register or the date of approval of a site-specific monitoring plan. The 
owner or operator of an affected facility who elects to continuously 
sample dioxin/furan emissions instead of sampling and testing using EPA 
Method 23 shall install, calibrate, maintain, and operate a continuous 
automated sampling system and shall comply with the requirements 
specified in paragraphs (p) and (q) of this section.

combustor unit capacity shall be calculated as the maximum design amount 
of municipal solid waste that can be charged per batch multiplied by the 
maximum number of batches that could be processed in a 24-hour period. 
The maximum number of batches that could be processed in a 24-hour 
period is calculated as 24 hours divided by the design number of hours 
required to process one batch of municipal solid waste, and may include 
fractional batches (e.g., if one batch requires 16 hours, then 24/16, or 
1.5 batches, could be combusted in a 24-hour period). For batch 
combustors that are designed based on heat capacity, the design

[[Page 301]]

heating value of 12,800 kilojoules per kilogram for combustors firing 
refuse-derived fuel and a heating value of 10,500 kilojoules per

    (1) During the performance tests for dioxins/furans and mercury, as 
applicable, the owner or operator shall estimate an average carbon mass 
feed rate based on carbon injection system operating parameters such as 
the screw feeder speed, hopper volume, hopper refill frequency, or other 
parameters appropriate to the feed system being employed, as specified 
in paragraphs (m)(1)(i) and (m)(1)(ii) of this section.
    (i) An average carbon mass feed rate in kilograms per hour or pounds 
per hour shall be estimated during the initial performance test for 
mercury emissions and each subsequent performance test for mercury 
emissions.
    (ii) An average carbon mass feed rate in kilograms per hour or 
pounds per hour shall be estimated during the initial performance test 
for dioxin/furan emissions and each subsequent performance test for 
dioxin/furan emissions. If a subsequent dioxin/furan performance test is 
being performed on only one affected facility at the MWC plant, as 
provided in paragraph (g)(5)(iii) of this section, the owner or operator 
may elect to apply the same estimated average carbon mass feed rate from 
the tested facility for all the similarly designed and operated affected 
facilities at the MWC plant.
    (2) During operation of the affected facility, the carbon injection 
system operating parameter(s) that are the primary indicator(s) of the 
carbon mass feed rate (e.g., screw feeder setting) shall be averaged 
over a block 8-

[[Page 302]]

hour period, and the 8-hour block average must equal or exceed the 
level(s) documented during the performance tests specified under 
paragraphs (m)(1)(i) and (m)(1)(ii) of this section, except as specified 
in paragraphs (m)(2)(i) and (m)(2)(ii) of this section.
    (i) During the annual dioxin/furan or mercury performance test and 
the 2 weeks preceding the annual dioxin/furan or mercury performance 
test, no limit is applicable for average mass carbon feed rate if the 
provisions of paragraph (m)(2)(ii) of this section are met.
    (ii) The limit for average mass carbon feed rate may be waived in 
accordance with permission granted by the Administrator for the purpose 
of evaluating system performance, testing new technology or control 
technologies, diagnostic testing, or related activities for the purpose 
of improving facility performance or advancing the state-of-the-art for 
controlling facility emissions.
    (3) The owner or operator of an affected facility shall estimate the 
total carbon usage of the plant (kilograms or pounds) for each calendar 
quarter by two independent methods, according to the procedures in

    (ii) Estimate the average carbon mass feed rate in kilograms per 
hour or pounds per hour for each hour of operation for each affected 
facility based on the parameters specified under paragraph (m)(1) of 
this section, and sum the results for all affected facilities at the 
plant for the total number of hours of operation during the calendar 
quarter.
    (4) Pneumatic injection pressure or other carbon injection system 
operational indicator shall be used to provide additional verification 
of proper carbon injection system operation. The operational indicator 
shall provide an instantaneous visual and/or audible alarm to alert the 
operator of a potential interruption in the carbon feed that would not 
normally be indicated by direct monitoring of carbon mass feed rate 
(e.g., continuous weight loss feeder) or monitoring of the carbon system 
operating parameter(s) that are the indicator(s) of carbon mass feed 
rate (e.g., screw feeder speed). The carbon injection system operational 
indicator used to provide additional verification of carbon injection 
system operation, including basis for selecting the indicator and 
operator response to the indicator alarm, shall be included in section 
(e)(6) of the site-specific operating manual required under Sec.

alternative ASTM D6784-02 (as applicable), the owner or operator of an 
affected facility may elect to install, calibrate, maintain, and operate 
a continuous emission monitoring system for monitoring emissions 
discharged to the atmosphere and record the output of the system. The 
option to use a continuous emission monitoring system for mercury takes 
effect on the date of approval of the site-specific monitoring plan 
required in paragraph (n)(13) and (o) of this section. The option to use

analysis of the impacts of the affected facility. The analysis shall 
consider air pollution control alternatives that minimize, on a site-
specific basis, to the maximum extent practicable, potential risks to 
public health or the environment. In considering such alternatives, the 
analysis may consider costs, energy impacts, non-air environmental 
impacts, or any other factors related to the practicability of the 
alternatives.
    (b) Analyses of facility impacts prepared to comply with State, 
local, or other Federal regulatory requirements may be used to satisfy 
the requirements of this section, as long as they include the 
consideration of air pollution control alternatives specified in 
paragraph (a) of this section.
    (c) The owner or operator of the affected facility shall complete 
and submit the siting requirements of this section as required under 
Sec. 60.58c(a)(1)(iii).



Sec. 60.55c  Waste management plan.

    The owner or operator of an affected facility shall prepare a waste 
management plan. The waste management plan shall identify both the 
feasibility and the approach to separate certain components of solid 
waste from the health care waste stream in order to reduce the amount of 
toxic emissions from incinerated waste. A waste management plan may 
include, but is not limited to, elements such as segregation and 
recycling of paper, cardboard, plastics, glass, batteries, food waste, 
and metals (e.g., aluminum cans, metals-containing devices); segregation 
of non-recyclable wastes (e.g., polychlorinated biphenyl-containing 
waste, pharmaceutical waste, and mercury-containing waste, such as 
dental

[[Page 325]]

waste); and purchasing recycled or recyclable products. A waste 
management plan may include different goals or approaches for different 
areas or departments of the facility and need not include new waste 
management goals for every waste stream. It should identify, where 
possible, reasonably available additional waste management measures, 
taking into account the effectiveness of waste management measures 
already in place, the costs of additional measures, the emissions 
reductions expected to be achieved, and any other environmental or 
energy impacts they might have. The American Hospital Association 
publication entitled ``An Ounce of Prevention: Waste Reduction 
Strategies for Health Care Facilities'' (incorporated by reference, see 
Sec. 60.17) shall be considered in the development of the waste 
management plan. The owner or operator of each commercial HMIWI company 
shall conduct training and education programs in waste segregation for 
each of the company's waste generator clients and ensure that each 
client prepares its own waste management plan that includes, but is not 
limited to, the provisions listed previously in this section.

Sec. 60.56c  Compliance and performance testing.

    (a) The emissions limits apply at all times.
    (b) The owner or operator of an affected facility as defined in 
Sec. 60.50c(a)(1) and (2), shall conduct an initial performance test as 
required under Sec. 60.8 to determine compliance with the emissions 
limits using the procedures and test methods listed in paragraphs (b)(1) 
through (b)(6) and (b)(9) through (b)(14) of this section. The owner or 
operator of an affected facility as defined in Sec. 60.50c(a)(3) and 
(4), shall conduct an initial performance test as required under Sec. 
60.8 to determine compliance with the emissions limits using the 
procedures and test methods listed in paragraphs (b)(1) through (b)(14). 
The use of the bypass stack during a performance test shall invalidate 
the performance test.
    (1) All performance tests shall consist of a minimum of three test 
runs conducted under representative operating conditions.
    (2) The minimum sample time shall be 1 hour per test run unless 
otherwise indicated.
    (3) EPA Reference Method 1 of appendix A of this part shall be used 
to select the sampling location and number of traverse points.
    (4) EPA Reference Method 3, 3A, or 3B of appendix A-2 of this part 
shall be used for gas composition analysis, including measurement of 
oxygen concentration. EPA Reference Method 3, 3A, or 3B of appendix A-2 
of this part shall be used simultaneously with each of the other EPA 
reference methods. As an alternative to EPA Reference Method 3B, ASME 
PTC-19-10-1981-Part 10 may be used (incorporated by reference, see Sec. 
60.17).
    (5) The pollutant concentrations shall be adjusted to 7 percent 
oxygen using the following equation:

Cadj = Cmeas (20.9-7)/(20.9-%O2)

where:

Cadj = pollutant concentration adjusted to 7 percent oxygen;
Cmeas = pollutant concentration measured on a dry basis 
          (20.9-7) = 20.9 percent oxygen--7 percent oxygen (defined 
          oxygen correction basis);
20.9 = oxygen concentration in air, percent; and
%O2 = oxygen concentration measured on a dry basis, percent.

    (6) EPA Reference Method 5 of appendix A-3 or Method 26A or Method 
29 of appendix A-8 of this part shall be used to measure the particulate 
matter emissions. As an alternative, PM CEMS may be used as specified in 
paragraph (c)(5) of this section.
    (7) EPA Reference Method 7 or 7E of appendix A-4 of this part shall 
be used to measure NOX emissions.

be used to measure SO2 emissions.
    (9) EPA Reference Method 9 of appendix A-4 of this part shall be 
used to measure stack opacity. As an alternative, demonstration of 
compliance with the PM standards using bag leak detection systems as 
specified in Sec. 60.57c(h) or PM CEMS as specified in paragraph (c)(5) 
of this section is considered demonstrative of compliance with the 
opacity requirements.

[[Page 326]]

    (10) EPA Reference Method 10 or 10B of appendix A-4 of this part 
shall be used to measure the CO emissions. As specified in paragraph 
(c)(4) of this section, use of CO CEMS are required for affected 
facilities under Sec. 60.50c(a)(3) and (4).
    (11) EPA Reference Method 23 of appendix A-7 of this part shall be 
used to measure total dioxin/furan emissions. As an alternative, an 
owner or operator may elect to sample dioxins/furans by installing, 
calibrating, maintaining, and operating a continuous automated sampling 
system for monitoring dioxin/furan emissions as specified in paragraph 
(c)(6) of this section. For Method 23 of appendix A-7 sampling, the 
minimum sample time shall be 4 hours per test run. If the affected 
facility has selected the toxic equivalency standards for dioxins/
furans, under Sec. 60.52c, the following procedures shall be used to 
determine compliance:
    (i) Measure the concentration of each dioxin/furan tetra-through 
octa-congener emitted using EPA Reference Method 23.
    (ii) For each dioxin/furan congener measured in accordance with 
paragraph (b)(9)(i) of this section, multiply the congener concentration 
by its corresponding toxic equivalency factor specified in table 2 of 
this subpart.
    (iii) Sum the products calculated in accordance with paragraph 
(b)(9)(ii) of this section to obtain the total concentration of dioxins/
furans emitted in terms of toxic equivalency.
    (12) EPA Reference Method 26 or 26A of appendix A-8 of this part 
shall be used to measure HCl emissions. As an alternative, HCl CEMS may 
be used as specified in paragraph (c)(5) of this section.
    (13) EPA Reference Method 29 of appendix A-8 of this part shall be 
used to measure Pb, Cd, and Hg emissions. As an alternative, Hg 
emissions may be measured using ASTM D6784-02 (incorporated by 
reference, see Sec. 60.17). As an alternative for Pb, Cd, and Hg, 
multi-metals CEMS or Hg CEMS, may be used as specified in paragraph 
(c)(5) of this section. As an alternative, an owner or operator may 
elect to sample Hg by installing, calibrating, maintaining, and 
operating a continuous automated sampling system for monitoring Hg 
emissions as specified in paragraph (c)(7) of this section.
    (14) The EPA Reference Method 22 of appendix A-7 of this part shall 
be used to determine compliance with the fugitive ash emissions limit 
under Sec. 60.52c(c). The minimum observation time shall be a series of 
three 1-hour observations.
    (c) Following the date on which the initial performance test is 
completed or is required to be completed under Sec. 60.8, whichever 
date comes first, the owner or operator of an affected facility shall:
    (1) Determine compliance with the opacity limit by conducting an 
annual performance test (no more than 12 months following the previous 
performance test) using the applicable procedures and test methods 
listed in paragraph (b) of this section.
    (2) Except as provided in paragraphs (c)(4) and (c)(5) of this 
section, determine compliance with the PM, CO, and HCl emissions limits 
by conducting an annual performance test (no more than 12 months 
following the previous performance test) using the applicable procedures 
and test methods listed in paragraph (b) of this section. If all three 
performance tests over a 3-year period indicate compliance with the 
emissions limit for a pollutant (PM, CO, or HCl), the owner or operator 
may forego a performance test for that pollutant for the subsequent 2 
years. At a minimum, a performance test for PM, CO, and HCl shall be 
conducted every third year (no more than 36 months following the 
previous performance test). If a performance test conducted every third 
year indicates compliance with the emissions limit for a pollutant (PM, 
CO, or HCl), the owner or operator may forego a performance test for 
that pollutant for an additional 2 years. If any performance test 
indicates noncompliance with the respective emissions limit, a 
performance test for that pollutant shall be conducted annually until 
all annual performance tests over a 3-year period indicate compliance 
with the emissions limit. The use of the bypass stack during a 
performance test shall invalidate the performance test.
    (3) For an affected facility as defined in Sec. 60.50c(a)(1) and 
(2) and utilizing a

[[Page 327]]

large HMIWI, and in Sec. 60.50c(a)(3) and (4), determine compliance 
with the visible emissions limits for fugitive emissions from flyash/
bottom ash storage and handling by conducting a performance test using 
EPA Reference Method 22 of appendix A-7 on an annual basis (no more than 
12 months following the previous performance test).
    (4) For an affected facility as defined in Sec. 60.50c(a)(3) and 
(4), determine compliance with the CO emissions limit using a CO CEMS 
according to paragraphs (c)(4)(i) through (c)(4)(iii) of this section:
    (i) Determine compliance with the CO emissions limit using a 24-hour 
block average, calculated as specified in section 12.4.1 of EPA 
Reference Method 19 of appendix A-7 of this part.
    (ii) Operate the CO CEMS in accordance with the applicable 
procedures under appendices B and F of this part.
    (iii) Use of a CO CEMS may be substituted for the CO annual 
performance test and minimum secondary chamber temperature to 
demonstrate compliance with the CO emissions limit.
    (5) Facilities using CEMS to demonstrate compliance with any of the 
emissions limits under Sec. 60.52c shall:
    (i) For an affected facility as defined in Sec. 60.50c(a)(1) and 
(2), determine compliance with the appropriate emissions limit(s) using 
a 12-hour rolling average, calculated each hour as the average of the 
previous 12 operating hours.
    (ii) For an affected facility as defined in Sec. 60.50c(a)(3) and 
(4), determine compliance with the appropriate emissions limit(s) using 
a 24-hour block average, calculated as specified in section 12.4.1 of 
EPA Reference Method 19 of appendix A-7 of this part.
    (iii) Operate all CEMS in accordance with the applicable procedures 
under appendices B and F of this part. For those CEMS for which 
performance specifications have not yet been promulgated (HCl, multi-
metals), this option for an affected facility as defined in Sec. 
60.50c(a)(3) and (4) takes effect on the date a final performance 
specification is published in the Federal Register or the date of 
approval of a site-specific monitoring plan.
    (iv) For an affected facility as defined in Sec. 60.50c(a)(3) and 
(4), be allowed to substitute use of an HCl CEMS for the HCl annual 
performance test, minimum HCl sorbent flow rate, and minimum scrubber 
liquor pH to demonstrate compliance with the HCl emissions limit.
    (v) For an affected facility as defined in Sec. 60.50c(a)(3) and 
(4), be allowed to substitute use of a PM CEMS for the PM annual 
performance test and minimum pressure drop across the wet scrubber, if 
applicable, to demonstrate compliance with the PM emissions limit.
    (6) An affected facility as defined in Sec. 60.50c(a)(3) and (4) 
using a continuous automated sampling system to demonstrate compliance 
with the dioxin/furan emissions limits under Sec. 60.52c shall record 
the output of the system and analyze the sample according to EPA 
Reference Method 23 of appendix A-7 of this part. This option to use a 
continuous automated sampling system takes effect on the date a final 
performance specification applicable to dioxin/furan from monitors is 
published in the Federal Register or the date of approval of a site-
specific monitoring plan. The owner or operator of an affected facility 
as defined in Sec. 60.50c(a)(3) and (4) who elects to continuously 
sample dioxin/furan emissions instead of sampling and testing using EPA 
Reference Method 23 of appendix A-7 shall install, calibrate, maintain, 
and operate a continuous automated sampling system and shall comply with 
the requirements specified in Sec. 60.58b(p) and (q) of subpart Eb of 
this part.
    (7) An affected facility as defined in Sec. 60.50c(a)(3) and (4) 
using a continuous automated sampling system to demonstrate compliance 
with the Hg emissions limits under Sec. 60.52c shall record the output 
of the system and analyze the sample at set intervals using any suitable 
determinative technique that can meet appropriate performance criteria. 
This option to use a continuous automated sampling system takes effect 
on the date a final performance specification applicable to Hg from 
monitors is published in the Federal Register or the date of approval of 
a site-specific monitoring plan. The owner or operator of an affected 
facility as defined in Sec. 60.50c(a)(3) and (4) who elects to 
continuously sample Hg

[[Page 328]]

emissions instead of sampling and testing using EPA Reference Method 29 
of appendix A-8 of this part, or an approved alternative method for 
measuring Hg emissions, shall install, calibrate, maintain, and operate 
a continuous automated sampling system and shall comply with the 
requirements specified in Sec. 60.58b(p) and (q) of subpart Eb of this 
part.
    (d) Except as provided in paragraphs (c)(4) through (c)(7) of this 
section, the owner or operator of an affected facility equipped with a 
dry scrubber followed by a fabric filter, a wet scrubber, or a dry 
scrubber followed by a fabric filter and wet scrubber shall:
    (1) Establish the appropriate maximum and minimum operating 
parameters, indicated in table 3 of this subpart for each control 
system, as site specific operating parameters during the initial 
performance test to determine compliance with the emission limits; and
    (2) Following the date on which the initial performance test is 
completed or is required to be completed under Sec. 60.8, whichever 
date comes first, ensure that the affected facility does not operate 
above any of the applicable maximum operating parameters or below any of 
the applicable minimum operating parameters listed in table 3 of this 
subpart and measured as 3-hour rolling averages (calculated each hour as 
the average of the previous 3 operating hours) at all times. Operating 
parameter limits do not apply during performance tests. Operation above 
the established maximum or below the established minimum operating 
parameter(s) shall constitute a violation of established operating 
parameter(s).
    (e) Except as provided in paragraph (i) of this section, for 
affected facilities equipped with a dry scrubber followed by a fabric 
filter:
    (1) Operation of the affected facility above the maximum charge rate 
and below the minimum secondary chamber temperature (each measured on a 
3-hour rolling average) simultaneously shall constitute a violation of 
the CO emission limit.
    (2) Operation of the affected facility above the maximum fabric 
filter inlet temperature, above the maximum charge rate, and below the 
minimum dioxin/furan sorbent flow rate (each measured on a 3-hour 
rolling average) simultaneously shall constitute a violation of the 
dioxin/furan emission limit.
    (3) Operation of the affected facility above the maximum charge rate 
and below the minimum HCl sorbent flow rate (each measured on a 3-hour 
rolling average) simultaneously shall constitute a violation of the HCl 
emission limit.
    (4) Operation of the affected facility above the maximum charge rate 
and below the minimum Hg sorbent flow rate (each measured on a 3-hour 
rolling average) simultaneously shall constitute a violation of the Hg 
emission limit.
    (5) Use of the bypass stack shall constitute a violation of the PM, 
dioxin/furan, HCl, Pb, Cd and Hg emissions limits.
    (6) Operation of the affected facility as defined in Sec. 
60.50c(a)(3) and (4) above the CO emissions limit as measured by the CO 
CEMS specified in paragraph (c)(4) of this section shall constitute a 
violation of the CO emissions limit.
    (7) For an affected facility as defined in Sec. 60.50c(a)(3) and 
(4), failure to initiate corrective action within 1 hour of a bag leak 
detection system alarm; or failure to operate and maintain the fabric 
filter such that the alarm is not engaged for more than 5 percent of the 
total operating time in a 6-month block reporting period shall 
constitute a violation of the PM emissions limit. If inspection of the 
fabric filter demonstrates that no corrective action is required, no 
alarm time is counted. If corrective action is required, each alarm is 
counted as a minimum of 1 hour. If it takes longer than 1 hour to 
initiate corrective action, the alarm time is counted as the actual 
amount of time taken to initiate corrective action. If the bag leak 
detection system is used to demonstrate compliance with the opacity 
limit, this would also constitute a violation of the opacity emissions 
limit.
    (8) Operation of the affected facility as defined in Sec. 
60.50c(a)(3) and (4) above the PM, HCl, Pb, Cd, and/or Hg emissions 
limit as measured by the CEMS

    (1) Operation of the affected facility above the maximum charge rate 
and below the minimum pressure drop across the wet scrubber or below the 
minimum horsepower or amperage to the system (each measured on a 3-hour 
rolling average) simultaneously shall constitute a violation of the PM

60.50c(a)(3) and (4) above the dioxin/furan emissions limit as measured 
by the continuous automated sampling system specified in paragraph 
(c)(6) of this section shall constitute a violation of the dioxin/furan 
emissions limit.
    (10) Operation of the affected facility as defined in Sec. 
60.50c(a)(3) and (4) above the Hg emissions limit as measured by the 
continuous automated sampling system specified in paragraph (c)(7) of

3-hour rolling average) simultaneously shall constitute a violation of 
the CO emission limit.
    (2) Operation of the affected facility above the maximum fabric 
filter inlet temperature, above the maximum charge rate, and below the 
minimum dioxin/furan sorbent flow rate (each measured on a 3-hour

emission limit.

[[Page 330]]

    (4) Operation of the affected facility above the maximum charge rate 
and below the minimum Hg sorbent flow rate (each measured on a 3-hour 
rolling average) simultaneously shall constitute a violation of the Hg 
emission limit.
    (5) Use of the bypass stack shall constitute a violation of the PM, 
dioxin/furan, HCl, Pb, Cd and Hg emissions limits.
    (6) Operation of the affected facility as defined in Sec. 
60.50c(a)(3) and (4) above the CO emissions limit as measured by the CO 
CEMS specified in paragraph (c)(4) of this section shall constitute a 
violation of the CO emissions limit.
    (7) For an affected facility as defined in Sec. 60.50c(a)(3) and

detection system alarm; or failure to operate and maintain the fabric 
filter such that the alarm is not engaged for more than 5 percent of the 
total operating time in a 6-month block reporting period shall 
constitute a violation of the PM emissions limit. If inspection of the 
fabric filter demonstrates that no corrective action is required, no 
alarm time is counted. If corrective action is required, each alarm is 
counted as a minimum of 1 hour. If it takes longer than 1 hour to 
initiate corrective action, the alarm time is counted as the actual 
amount of time taken to initiate corrective action. If the bag leak 
detection system is used to demonstrate compliance with the opacity 
limit, this would also constitute a violation of the opacity emissions

60.50c(a)(3) and (4) above the Hg emissions limit as measured by the 
continuous automated sampling system specified in paragraph (c)(7) of 
this section shall constitute a violation of the Hg emissions limit.
    (h) The owner or operator of an affected facility as defined in 
Sec. 60.50c(a)(3) and (4) equipped with selective noncatalytic 
reduction technology shall:
    (1) Establish the maximum charge rate, the minimum secondary chamber 
temperature, and the minimum reagent flow rate as site specific 
operating parameters during the initial performance test to determine 
compliance with the emissions limits;
    (2) Following the date on which the initial performance test is 
completed or is required to be completed under Sec. 60.8, whichever 
date comes first, ensure that the affected facility does not operate

[[Page 332]]

obtains written approval from the Administrator establishing a date 
whereby all necessary repairs of the designated facility shall be 
completed.
    (g) The owner or operator of an affected facility as defined in 
Sec. 60.50c(a)(3) and (4) shall ensure that each HMIWI subject to the 
emissions limits under Sec. 60.52c undergoes an air pollution control 
device inspection annually (no more than 12 months following the 
previous annual air pollution control device inspection), as outlined in 
paragraphs (f)(1) and (f)(2) of this section.
    (h) For affected facilities as defined in Sec. 60.50c(a)(3) and (4) 
that use an air pollution control device that includes a fabric filter 
and are not demonstrating compliance using PM CEMS, determine compliance 
with the PM emissions limit using a bag leak detection system and meet 
the requirements in paragraphs (h)(1) through (h)(12) of this section 
for each bag leak detection system.
    (1) Each triboelectric bag leak detection system may be installed, 
calibrated, operated, and maintained according to the ``Fabric Filter 
Bag Leak Detection Guidance,'' (EPA-454/R-98-015, September 1997). This 
document is available from the U.S. Environmental Protection Agency 
(U.S. EPA); Office of Air Quality Planning and Standards; Sector 
Policies and Programs Division; Measurement Policy Group (D-243-02), 
Research Triangle Park, NC 27711. This document is also available on the 
Technology Transfer Network (TTN) under Emissions Measurement Center 
Continuous Emissions Monitoring. Other types of bag leak detection 
systems shall be installed, operated, calibrated, and maintained in a 
manner consistent with the manufacturer's written specifications and 
recommendations.
    (2) The bag leak detection system shall be certified by the 
manufacturer to be capable of detecting PM emissions at concentrations 
of 10 milligrams per actual cubic meter (0.0044 grains per actual cubic 
foot) or less.
    (3) The bag leak detection system sensor shall provide an output of 
relative PM loadings.
    (4) The bag leak detection system shall be equipped with a device to 
continuously record the output signal from the sensor.
    (5) The bag leak detection system shall be equipped with an audible 
alarm system that will sound automatically when an increase in relative 
PM emissions over a preset level is detected. The alarm shall be located 
where it is easily heard by plant operating personnel.
    (6) For positive pressure fabric filter systems, a bag leak detector 
shall be installed in each baghouse compartment or cell.
    (7) For negative pressure or induced air fabric filters, the bag 
leak detector shall be installed downstream of the fabric filter.
    (8) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (9) The baseline output shall be established by adjusting the range 
and the averaging period of the device and establishing the alarm set 
points and the alarm delay time according to section 5.0 of the ``Fabric 
Filter Bag Leak Detection Guidance.''
    (10) Following initial adjustment of the system, the sensitivity or 
range, averaging period, alarm set points, or alarm delay time may not 
be adjusted. In no case may the sensitivity be increased by more than 
100 percent or decreased more than 50 percent over a 365-day period 
unless such adjustment follows a complete fabric filter inspection that 
demonstrates that the fabric filter is in good operating condition. Each 
adjustment shall be recorded.
    (11) Record the results of each inspection, calibration, and 
validation check.
    (12) Initiate corrective action within 1 hour of a bag leak 
detection system alarm; operate and maintain the fabric filter such that 
the alarm is not engaged for more than 5 percent of the total operating 
time in a 6-month block reporting period. If inspection of the fabric 
filter demonstrates that no corrective action is required, no alarm time 
is counted. If corrective action is required, each alarm is counted as a 
minimum of 1 hour. If it takes longer than 1 hour to initiate corrective 
action, the alarm time is counted as the

[[Page 333]]

actual amount of time taken to initiate corrective action.

      Subpart F_Standards of Performance for Portland Cement Plants



Sec. 60.60  Applicability and designation of affected facility.

    (a) The provisions of this subpart are applicable to the following 
affected facilities in portland cement plants: Kiln, clinker cooler, raw 
mill system, finish mill system, raw mill dryer, raw material storage, 
clinker storage, finished product storage, conveyor transfer points, 
bagging and bulk loading and unloading systems.
    (b) Any facility under paragraph (a) of this section that commences 
construction or modification after August 17, 1971, is subject to the 
requirements of this subpart.

[42 FR 37936, July 25, 1977]



Sec. 60.61  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A of this part.
    (a) Portland cement plant means any facility manufacturing portland 
cement by either the wet or dry process.
    (b) Bypass means any system that prevents all or a portion of the 
kiln or clinker cooler exhaust gases from entering the main control 
device and ducts the gases through a separate control device. This does 
not include emergency systems designed to duct exhaust gases directly to 
the atmosphere in the event of a malfunction of any control device 
controlling kiln or clinker cooler emissions.
    (c) Bypass stack means the stack that vents exhaust gases to the 
atmosphere from the bypass control device.
    (d) Monovent means an exhaust configuration of a building or 
emission control device (e.g., positive-pressure fabric filter) that 
extends the length of the structure and has a width very small in 
relation to its length (i.e., length to width ratio is typically greater 
than 5:1). The exhaust may be an open vent with or without a roof, 
louvered vents, or a combination of such features.

[[Page 339]]

    (e) Excess emissions means, with respect to this subpart, results of 
any required measurements outside the applicable range (e.g., emissions 
limitations, parametric operating limits) that is permitted by this 
subpart. The values of measurements will be in the same units and 
averaging time as the values specified in this subpart for the 
limitations.
    (f) Operating day means a 24-hour period beginning at 12:00 midnight 
during which the kiln produces clinker at any time. For calculating 30 
day rolling average emissions, an operating day does not include the 
hours of operation during startup or shutdown.
    (g) Rolling average means the weighted average of all data, meeting 
QA/QC requirements or otherwise normalized, collected during the 
applicable averaging period. The period of a rolling average stipulates 
the frequency of data averaging and reporting. To demonstrate compliance 
with an operating parameter a 30-day rolling average period requires 
calculation of a new average value each operating day and shall include 
the average of all the hourly averages of the specific operating 
parameter. For demonstration of compliance with an emissions limit based 
on pollutant concentration, a 30-day rolling average is comprised of the 
average of all the hourly average concentrations over the previous 30 
operating days. For demonstration of compliance with an emissions limit 
based on lbs-pollutant per production unit, the 30-day rolling average 
is calculated by summing the hourly mass emissions over the previous 30 
operating days, then dividing that sum by the total production during 
the same period.
    (h) Run average means the average of the recorded parameter values 
for a run.

Sec. 60.62  Standards.

    (a) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, you may not discharge into the 
atmosphere from any kiln any gases which:
    (1) Contain particulate matter (PM) in excess of:
    (i) 0.30 pounds per ton of feed (dry basis) to the kiln for kilns 
constructed, reconstructed, or modified after August 17, 1971 but on or 
before June 16, 2008.
    (ii) 0.02 pound per ton of clinker if construction or reconstruction 
of the kiln commenced after June 16, 2008.
    (iii) Kilns that have undergone a modification may not discharge 
into the atmosphere any gases which contain PM in excess of 0.07 pound 
per ton of clinker.
    (2) Exhibit greater than 20 percent opacity for kilns constructed, 
reconstructed, or modified after August 17, 1971 but on or before June 
16, 2008, except that this opacity limit does not apply to any kiln 
subject to a PM limit in paragraph (a)(1) of this section that uses a PM 
continuous parametric monitoring system (CPMS).
    (3) Exceed 1.50 pounds of nitrogen oxide (NOX) per ton of 
clinker on a 30-operating day rolling average if construction, 
reconstruction, or modification of the kiln commences after June 16, 
2008, except this limit does not apply to any alkali bypass installed on 
the kiln. An operating day includes all valid data obtained in any daily 
24-hour period during which the kiln operates and excludes any 
measurements made during the daily 24-hour period when the kiln was not 
operating.
    (4) Exceed 0.4 pounds of sulfur dioxide (SO2) per ton of 
clinker on a 30-operating day rolling average if construction, 
reconstruction, or modification commences after June 16, 2008, unless 
you are demonstrating a 90 percent SO2 emissions reduction 
measured across the SO2 control device. An operating day 
includes all valid data obtained in any daily 24-hour period during 
which the kiln operates, and excludes any measurements made during the 
daily 24-hour period when the kiln was not operating.
    (b) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, you may not discharge into the 
atmosphere from any clinker cooler any gases which:
    (1) Contain PM in excess of:

[[Page 340]]

    (i) 0.02 pound per ton of clinker if construction or reconstruction 
of the clinker cooler commences after June 16, 2008.
    (ii) 0.07 pound per ton of clinker if the clinker cooler has 
undergone a modification.
    (iii) 0.10 lb per ton of feed (dry basis) for clinker coolers 
constructed, reconstructed, or modified after August 17, 1971, but on or 
before June 16, 2008.
    (iv) 10 percent opacity for clinker coolers constructed, 
reconstructed, or modified after August 17, 1971, but on or before June 
16, 2008, except that this opacity limit does not apply to any clinker 
cooler subject to a PM limit in paragraph (b)(1) of this section that 
uses a PM continuous parametric monitoring system (CPMS).
    (2) If the kiln and clinker cooler exhaust are combined for energy 
efficiency purposes and sent to a single control device, the appropriate 
kiln PM limit may be adjusted using the procedures in Sec. 63.1343(b) 
of this chapter.
    (3) If the kiln has a separated alkali bypass stack and/or an inline 
coal mill with a separate stack, you must combine the PM emissions from 
the bypass stack and/or the inline coal mill stack with the PM emissions 
from the main kiln exhaust to determine total PM emissions.
    (c) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, you may not discharge into the 
atmosphere from any affected facility other than the kiln and clinker 
cooler any gases which exhibit 10 percent opacity, or greater.
    (d) If you have an affected source subject to this subpart with a 
different emissions limit or requirement for the same pollutant under 
another regulation in title 40 of this chapter, once you are in 
compliance with the most stringent emissions limit or requirement, you 
are not subject to the less stringent requirement. Until you are in 
compliance with the more stringent limit, the less stringent limit 
continues to apply.
    (e) The compliance date for all revised monitoring and recordkeeping 
requirements contained in this rule will be the same as listed in 
63.1351(c) unless you commenced construction as of June 16, 2008, at 
which time the compliance date is November 8, 2010 or upon startup, 
whichever is later.

Sec. 60.63  Monitoring of operations.

    (a) [Reserved]
    (b) Clinker production monitoring requirements. For any kiln subject 
to an emissions limitation on PM, NOX, or SO2 
emissions (lb/ton of clinker), you must:
    (1) Determine hourly clinker production by one of two methods:
    (i) Install, calibrate, maintain, and operate a permanent weigh 
scale system to measure and record weight rates of the amount of clinker 
produced in tons of mass per hour. The system of measuring hourly 
clinker production must be maintained within 5 
percent accuracy or
    (ii) Install, calibrate, maintain, and operate a permanent weigh 
scale system to measure and record weight rates of the amount of feed to 
the kiln in tons of mass per hour. The system of measuring feed must be 
maintained within 5 percent accuracy. Calculate 
your hourly clinker production rate using a kiln specific feed-to-
clinker ratio based on reconciled clinker production rates determined 
for accounting purposes and recorded feed rates. This ratio should be 
updated monthly. Note that if this ratio changes at clinker 
reconciliation, you must use the new ratio going forward, but you do not 
have to retroactively change clinker production rates previously 
estimated.
    (iii) For each kiln operating hour for which you do not have data on 
clinker production or the amount of feed to the kiln, use the value from 
the most recent previous hour for which valid data are available.
    (2) Determine, record, and maintain a record of the accuracy of the 
system of measuring hourly clinker production rates or feed rates before 
initial use (for new sources) or by the effective compliance date of 
this rule (for existing sources). During each quarter of source 
operation, you must determine, record, and maintain a record of the

[[Page 341]]

ongoing accuracy of the system of measuring hourly clinker production 
rates or feed rates.
    (3) If you measure clinker production directly, record the daily 
clinker production rates; if you measure the kiln feed rates and 
calculate clinker production, record the daily kiln feed and clinker 
production rates.
    (c) PM Emissions Monitoring Requirements. (1) For each kiln or 
clinker cooler subject to a PM emissions limit in Sec. Sec. 
60.62(a)1(ii) and 60.62(a)1(iii) or Sec. Sec. 60.62(b)(1)(i) and 
60.62(b)(1)(ii), you must demonstrate compliance through an initial 
performance test. You will conduct your performance test using Method 5 
or Method 5I at appendix A-3 to part 60 of this chapter. You must also 
monitor continuous performance through use of a PM CPMS.
    (2) For your PM CPMS, you will establish a site-specific operating 
limit. If your PM performance test demonstrates your PM emission levels 
to be below 75 percent of your emission limit you will use the average 
PM CPMS value recorded during the PM compliance test, the milliamp 
equivalent of zero output from your PM CPMS, and the average PM result 
of your compliance test to establish your operating limit equivalent to 
75 percent of the standard. If your PM compliance test demonstrates your 
PM emission levels to be at or above 75 percent of your emission limit 
you will use the average PM CPMS value recorded during the PM compliance 
test demonstrating compliance with the PM limit to establish your 
operating limit. You will use the PM CPMS to demonstrate continuous 
compliance with your operating limit. You must repeat the performance 
test annually and reassess and adjust the site-specific operating limit 
in accordance with the results of the performance test.
    (i) Your PM CPMS must provide a 4-20 milliamp or digital signal 
output and the establishment of its relationship to manual reference 
method measurements must be determined in units of milliamps or the 
monitors digital equivalent.
    (ii) Your PM CPMS operating range must be capable of reading PM 
concentrations from zero to a level equivalent to two times your 
allowable emission limit. If your PM CPMS is an auto-ranging instrument 
capable of multiple scales, the primary range of the instrument must be 
capable of reading PM concentration from zero to a level equivalent to 
two times your allowable emission limit.
    (iii) During the initial performance test or any such subsequent 
performance test that demonstrates compliance with the PM limit, record 
and average all milliamp or digital output values from the PM CPMS for 
the periods corresponding to the compliance test runs (e.g., average all 
your PM CPMS output values for three corresponding 2-hour Method 5I test 
runs).
    (3) Determine your operating limit as specified in paragraphs 
(c)(4)(i) through (c)(5) of this section. If your PM performance test 
demonstrates your PM emission levels to be below 75 percent of your 
emission limit, you will use the average PM CPMS value recorded during 
the PM compliance test, the milliamp or digital equivalent of zero 
output from your PM CPMS, and the average PM result of your compliance 
test to establish your operating limit. If your PM compliance test 
demonstrates your PM emission levels to be at or above 75 percent of 
your emission limit, you will use the average PM CPMS value recorded 
during the PM compliance test to establish your operating limit. You 
must verify an existing or establish a new operating limit after each 
repeated performance test. You must repeat the performance test at least 
annually and reassess and adjust the site-specific operating limit in 
accordance with the results of the performance test.
    (4) If the average of your three Method 5 or 5I compliance test runs 
are below 75 percent of your PM emission limit, you must calculate an 
operating limit by establishing a relationship of PM CPMS signal to PM 
concentration using the PM CPMS instrument zero, the average PM CPMS 
values corresponding to the three compliance test runs, and the average 
PM concentration from the Method 5 or 5I compliance test with the 
procedures in (c)(4)(i)(A) through (D) of this section.
    (i) Determine your PM CPMS instrument zero output with one of the 
following procedures.

[[Page 342]]

    (A) Zero point data for in-situ instruments should be obtained by 
removing the instrument from the stack and monitoring ambient air on a 
test bench.
    (B) Zero point data for extractive instruments should be obtained by 
removing the extractive probe from the stack and drawing in clean 
ambient air.
    (C) The zero point can also can be obtained by performing manual 
reference method measurements when the flue gas is free of PM emissions 
or contains very low PM concentrations (e.g., when your process is not 
operating, but the fans are operating or your source is combusting only 
natural gas) and plotting these with the compliance data to find the 
zero intercept.
    (D) If none of the steps in paragraphs (c)(4)(i)(A) through (C) of 
this section are possible, you must use a zero output value provided by 
the manufacturer.
    (ii) Determine your PM CPMS instrument average in milliamps or 
digital equivalent and the average of your corresponding three PM 
compliance test runs, using equation 1.
[GRAPHIC] [TIFF OMITTED] TR27JY15.006


Where:

X1 = The PM CPMS data points for the three runs constituting 
          the performance test,
Y1 = The PM concentration value for the three runs 
          constituting the performance test, and
n = The number of data points.

    (iii) With your PM CPMS instrument zero expressed in milliamps or a 
digital value, your three run average PM CPMS milliamp or digital signal 
value, and your three run average PM concentration from your three PM 
performance test runs, determine a relationship of lb/ton-clinker per 
milliamp or digital signal with equation 2.
[GRAPHIC] [TIFF OMITTED] TR27JY15.007


Where:

R = The relative lb/ton clinker per milliamp or digital equivalent for 
          your PM CPMS.
Y1 = The three run average PM lb/ton clinker.
X1 = The three run average milliamp or digital signal output 
          from your PM CPMS.
z = The milliamp or digital equivalent of your instrument zero 
          determined from (c)(4)(i) of this section.

    (iv) Determine your source specific 30-day rolling average operating 
limit using the lb/ton-clinker per milliamp or digital signal value from 
Equation 2 above in Equation 3, below. This sets your operating limit at 
the PM CPMS output value corresponding to 75 percent of your emission 
limit.
[GRAPHIC] [TIFF OMITTED] TR27JY15.008


Where:

Ol = The operating limit for your PM CPMS on a 30-day rolling 
          average, in milliamps or the digital equivalent.

[[Page 343]]

L = Your source emission limit expressed in lb/ton clinker.
z = Your instrument zero in milliamps or a digital equivalent, 
          determined from (1)(i).
R = The relative lb/ton-clinker per milliamp or digital equivalent, for 
          your PM CPMS, from Equation 2.

    (5) If the average of your three PM compliance test runs is at or 
above 75 percent of your PM emission limit, you must determine your 
operating limit by averaging the PM CPMS milliamp or digital equivalent 
output corresponding to your three PM performance test runs that 
demonstrate compliance with the emission limit using Equation 4.
[GRAPHIC] [TIFF OMITTED] TR27JY15.009


Where:

X1 = The PM CPMS data points for all runs i.
n = The number of data points.
Oh = Your site specific operating limit, in milliamps or 
          digital equivalent.

    (6) To determine continuous compliance, you must record the PM CPMS 
output data for all periods when the process is operating, and use all 
the PM CPMS data for calculations when the source is not out-of-control. 
You must demonstrate continuous compliance by using all quality-assured 
hourly average data collected by the PM CPMS for all operating hours to 
calculate the arithmetic average operating parameter in units of the 
operating limit (milliamps or the digital equivalent) on a 30 operating 
day rolling average basis, updated at the end of each new kiln operating 
day. Use Equation 5 to determine the 30 kiln operating day average.
[GRAPHIC] [TIFF OMITTED] TR27JY15.010


Where:

Hpvi = The hourly parameter value for hour i.
n = The number of valid hourly parameter values collected over the 
          previous 30 kiln operating days.

    (7) Use EPA Method 5 or Method 5I of appendix A to part 60 of this 
chapter to determine PM emissions. For each performance test, conduct at 
least three separate runs each while the mill is on and the mill is off 
under the conditions that exist when the affected source is operating at 
the level reasonably expected to occur. Conduct each test run to collect 
a minimum sample volume of 2 dscm for determining compliance with a new 
source limit and 1 dscm for determining compliance with an existing 
source limit. Calculate the time weighted average of the results from 
three consecutive runs to determine compliance. You need not determine 
the particulate matter collected in the impingers (``back half'') of the 
Method 5 or Method 5I particulate sampling train to demonstrate 
compliance with the PM standards of this subpart. This shall not 
preclude the permitting authority from requiring a determination of the 
``back half'' for other purposes.
    (8) For PM performance test reports used to set a PM CPMS operating 
limit, the electronic submission of the test report must also include 
the make and model of the PM CPMS instrument, serial number of the 
instrument, analytical principle of the instrument (e.g. beta 
attenuation), span of the instruments primary analytical range, milliamp 
or digital signal value equivalent to the instrument zero output,

[[Page 344]]

technique by which this zero value was determined, and the average 
milliamp or digital equivalent signals corresponding to each PM 
compliance test run.
    (d) You must install, operate, calibrate, and maintain a CEMS 
continuously monitoring and recording the concentration by volume of 
NOX emissions into the atmosphere for any kiln subject to the 
NOX emissions limit in Sec. 60.62(a)(3). If the kiln has an 
alkali bypass, NOX emissions from the alkali bypass do not 
need to be monitored, and NOX emission monitoring of the kiln 
exhaust may be done upstream of any commingled alkali bypass gases.
    (e) You must install, operate, calibrate, and maintain a CEMS for 
continuously monitoring and recording the concentration by volume of 
SO2 emissions into the atmosphere for any kiln subject to the 
SO2 emissions limit in Sec. 60.62(a)(4). If you are 
complying with the alternative 90 percent SO2 emissions 
reduction emissions limit, you must also continuously monitor and record 
the concentration by volume of SO2 present at the wet 
scrubber inlet.
    (f) The NOX and SO2 CEMS required under 
paragraphs (d) and (e) of this section must be installed, operated and 
maintained according to Performance Specification 2 of appendix B of 
this part and the requirements in paragraphs (f)(1) through (5) of this 
section.
    (1) The span value of each NOX CEMS monitor must be set 
at 125 percent of the maximum estimated hourly potential NOX 
emission concentration that translates to the applicable emissions limit 
at full clinker production capacity.
    (2) You must conduct performance evaluations of each NOX 
CEMS monitor according to the requirements in Sec. 60.13(c) and 
Performance Specification 2 of appendix B to this part. You must use 
Methods 7, 7A, 7C, 7D, or 7E of appendix A-4 to this part for conducting 
the relative accuracy evaluations. The method ASME PTC 19.10-1981, 
``Flue and Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 
60.17) is an acceptable alternative to Method 7 or 7C of appendix A-4 to 
this part.
    (3) The span value for the SO2 CEMS monitor is the 
SO2 emission concentration that corresponds to 125 percent of 
the applicable emissions limit at full clinker production capacity and 
the expected maximum fuel sulfur content.
    (4) You must conduct performance evaluations of each SO2 
CEMS monitor according to the requirements in Sec. 60.13(c) and 
Performance Specification 2 of appendix B to this part. You must use 
Methods 6, 6A, or 6C of appendix A-4 to this part for conducting the 
relative accuracy evaluations. The method ASME PTC 19.10-1981, ``Flue 
and Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 60.17) 
is an acceptable alternative to Method 6 or 6A of appendix A-4 to this 
part.
    (5) You must comply with the quality assurance requirements in 
Procedure 1 of appendix F to this part for each NOX and 
SO2 CEMS, including quarterly accuracy determinations for 
monitors, and daily calibration drift tests.
    (g) For each CPMS or CEMS required under paragraphs (c) through (e) 
of this section:
    (1) You must operate the monitoring system and collect data at all 
required intervals at all times the affected source is operating, except 
for periods of monitoring system malfunctions, repairs associated with 
monitoring system malfunctions, and required monitoring system quality 
assurance or quality control activities (including, as applicable, 
calibration checks and required zero and span adjustments).
    (2) You may not use data recorded during the monitoring system 
malfunctions, repairs associated with monitoring system malfunctions, or 
required monitoring system quality assurance or control activities in 
calculations used to report emissions or operating levels. A monitoring 
system malfunction is any sudden, infrequent, not reasonably preventable 
failure of the monitoring system to provide valid data. Monitoring 
system failures that are caused in part by poor maintenance or careless 
operation are not malfunctions. An owner or operator must use all the 
data collected during all other periods in reporting emissions or 
operating levels.
    (3) You must meet the requirements of Sec. 60.13(h) when 
determining the 1-hour averages of emissions data.

[[Page 345]]

    (h) You must install, operate, calibrate, and maintain instruments 
for continuously measuring and recording the stack gas flow rate to 
allow determination of the pollutant mass emissions rate to the 
atmosphere for each kiln subject to the PM emissions limits in Sec. 
60.62(a)(1)(ii) and (iii) and (b)(1)(i) and (ii), the NOX 
emissions limit in Sec. 60.62(a)(3), or the SO2 emissions

monitoring system in a location that provides representative measurement 
of the exhaust gas flow rate at the sampling location of the 
NOX and/or SO2 CEMS, taking into account the 
manufacturer's recommendations. The flow rate sensor is that portion of 
the system that senses the volumetric flow rate and generates an output 
proportional to that flow rate.
    (2) The flow rate monitoring system must be designed to measure the 
exhaust gas flow rate over a range that extends from a value of at least 
20 percent less than the lowest expected exhaust flow rate to a value of 
at least 20 percent greater than the highest expected exhaust gas flow 
rate.
    (3) The flow rate monitoring system must have a minimum accuracy of 
5 percent of the flow rate.
    (4) The flow rate monitoring system must be equipped with a data 
acquisition and recording system that is capable of recording values 
over the entire range specified in paragraph (h)(2) of this section.
    (5) The signal conditioner, wiring, power supply, and data 
acquisition and recording system for the flow rate monitoring system 
must be compatible with the output signal of the flow rate sensors used 
in the monitoring system.
    (6) The flow rate monitoring system must be designed to measure a 
minimum of one cycle of operational flow for each successive 15-minute 
period.
    (7) The flow rate sensor must be able to determine the daily zero 
and upscale calibration drift (CD) (see sections 3.1 and 8.3 of 
Performance Specification 2 in appendix B to this part for a discussion 
of CD).
    (i) Conduct the CD tests at two reference signal levels, zero (e.g., 
0 to 20 percent of span) and upscale (e.g., 50 to 70 percent of span).
    (ii) The absolute value of the difference between the flow monitor 
response and the reference signal must be equal to or less than 3 
percent of the flow monitor span.
    (8) You must perform an initial relative accuracy test of the flow 
rate monitoring system according to section 8.2 of Performance 
Specification 6 of appendix B to this part, with the exceptions noted in 
paragraphs (h)(8)(i) and (ii) of this section.
    (i) The relative accuracy test is to evaluate the flow rate 
monitoring system alone rather than a continuous emission rate 
monitoring system.
    (ii) The relative accuracy of the flow rate monitoring system shall 
be no greater than 10 percent of the mean value of the reference method 
data.
    (9) You must verify the accuracy of the flow rate monitoring system 
at least once per year by repeating the relative accuracy test specified 
in paragraph (h)(8) of this section.
    (10) You must operate the flow rate monitoring system and record 
data during all periods of operation of the affected facility including 
periods of startup, shutdown, and malfunction, except for periods of 
monitoring system malfunctions, repairs associated with monitoring 
system malfunctions, and required monitoring system quality assurance or 
quality control activities (including, as applicable, calibration checks 
and required zero and span adjustments.
    (i) Development and Submittal (Upon Request) of Monitoring Plans. To 
demonstrate compliance with any applicable emissions limit through 
performance stack testing or other emissions monitoring (including PM 
CPMS), you must develop a site-specific monitoring plan according to the 
requirements in paragraphs (i)(1) through (4) of this section. This 
requirement also applies to you if you petition the EPA Administrator 
for alternative monitoring parameters under Sec. 60.13(3)(i). If you 
use a bag leak detector system (BLDS), you must also meet the 
requirements specified in paragraph Sec. 63.1350(m)(10) of this 
chapter.

[[Page 346]]

    (1) For each continuous monitoring system (CMS) required in this 
section, you must develop, and submit to the permitting authority for 
approval upon request, a site-specific monitoring plan that addresses 
paragraphs (i)(1)(i) through (iii) of this section. You must submit this 
site-specific monitoring plan, if requested, at least 30 days before the 
initial performance evaluation of your CMS.
    (i) Installation of the CMS sampling probe or other interface at a 
measurement location relative to each affected process unit such that 
the measurement is representative of control of the exhaust emissions 
(e.g., on or downstream of the last control device);
    (ii) Performance and equipment specifications for the sample 
interface, the pollutant concentration or parametric signal analyzer, 
and the data collection and reduction systems; and
    (iii) Performance evaluation procedures and acceptance criteria 
(e.g., calibrations).

Acceptable alternative methods and procedures are given in paragraph (c) 
of this section.
    (b) The owner or operator shall determine compliance with the 
NOX standard in Sec. 60.72 as follows:
    (1) The emission rate (E) of NOX shall be computed for 
each run using the following equation:

E = (Cs Qsd)/(P K)

where:

E = emission rate of NOX as NO2, kg/metric ton 
          (lb/ton) of 100 percent nitric acid.
Cs = concentration of NOX as NO2, g/
          dscm (lb/dscf).
Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/

concentration of each grab sample. Method 1 shall be used to select the 
sampling site, and the sampling point shall be the centroid of the stack 
or duct or at a point no closer to the walls than 1 m (3.28 ft). Four 
grab samples shall be taken at approximately 15-minute intervals. The 
arithmetic mean of the four sample concentrations shall constitute the 
run value (Cs).
    (3) Method 2 shall be used to determine the volumetric flow rate 
(Qsd) of the effluent gas. The measurement site shall be the 
same as for the NOX sample. A velocity traverse shall be made 
once per run within the hour that the NOX samples are taken.
    (4) The methods of Sec. 60.73(c) shall be used to determine the 
production rate (P) of 100 percent nitric acid for each run. Material 
balance over the production system shall be used to confirm the 
production rate.
    (c) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) For Method 7, Method 7A, 7B, 7C, or 7D may be used. If Method 7C 
or 7D is used, the sampling time shall be at least 1 hour.

    Weak nitric acid means acid which is 30 to 70 percent in strength.



Sec. 60.72a  Standards.

    Nitrogen oxides. On and after the date on which the performance test 
required to be conducted by Sec. 60.73a(e) is completed, you may not 
discharge into the atmosphere from any affected facility any gases which 
contain NOX, expressed as NO2, in excess of 0.50 
pounds (lb) per ton of nitric acid produced, as a 30-day emission rate 
calculated based on 30 consecutive operating days, the production being 
expressed as 100 percent nitric acid. The emission standard applies at 
all times.



Sec. 60.73a  Emissions testing and monitoring.

    (a) General emissions monitoring requirements. You must install and 
operate a NOX concentration (ppmv) continuous emissions 
monitoring system (CEMS). You must also install and operate a stack gas 
flow rate monitoring system. With measurements of stack gas 
NOX concentration and stack gas flow rate, you will determine 
hourly NOX emissions rate (e.g., lb/hr) and with measured 
data of the hourly nitric acid production (tons), calculate emissions in 
units of the applicable emissions limit (lb/ton of 100 percent acid 
produced). You must operate the monitoring system and report emissions 
during all operating periods including unit startup and shutdown, and 
malfunction.
    (b) Nitrogen oxides concentration continuous emissions monitoring 
system. (1) You must install, calibrate, maintain, and operate a CEMS 
for measuring and recording the concentration of NOX 
emissions in accordance with the provisions of Sec. 60.13 and 
Performance Specification 2 of appendix B and Procedure 1 of appendix F 
of this part. You must use cylinder gas audits to fulfill the quarterly 
auditing requirement at section 5.1 of Procedure 1 of appendix F of this 
part for the NOX concentration CEMS.
    (2) For the NOX concentration CEMS, use a span value, as 
defined in Performance Specification 2, section 3.11, of appendix B of 
this part, of 500 ppmv (as NO2). If you emit NOX 
at concentrations higher than 600 ppmv (e.g., during startup or shutdown 
periods), you must apply a second CEMS or dual range CEMS and a second 
span value equal to

[[Page 351]]

125 percent of the maximum estimated NOX emission 
concentration to apply to the second CEMS or to the higher of the dual 
analyzer ranges during such periods.
    (3) For conducting the relative accuracy test audits, per 
Performance Specification 2, section 8.4, of appendix B of this part and 
Procedure 1, section 5.1.1, of appendix F of this part, use either EPA 
Reference Method 7, 7A, 7C, 7D, or 7E of appendix A-4 of this part; EPA 
Reference Method 320 of appendix A of part 63 of this chapter; or ASTM 
D6348-03 (incorporated by reference, see Sec. 60.17). To verify the 
operation of the second CEMS or the higher range of a dual analyzer CEMS 
described in paragraph (b)(2) of this section, you need not conduct a 
relative accuracy test audit but only the calibration drift test 
initially (found in Performance Specification 2, section 8.3.1, of 
appendix B of this part) and the cylinder gas audit thereafter (found in 
Procedure 1, section 5.1.2, of appendix F of this part).
    (4) If you use EPA Reference Method 7E of appendix A-4 of this part, 
you must mitigate loss of NO2 in water according to the 
requirements in paragraphs (b)(4)(i), (ii), or (iii) of this section and 
verify performance by conducting the system bias checks required in EPA 
Reference Method 7E, section 8, of appendix A-4 of this part according 
to (b)(4)(iv) of this section, or follow the dynamic spike procedure 
according to paragraph (b)(4)(v) of this section.
    (i) For a wet-basis measurement system, you must measure and report 
temperature of sample line and components (up to analyzer inlet) to 
demonstrate that the temperatures remain above the sample gas dew point 
at all times during the sampling.
    (ii) You may use a dilution probe to reduce the dew point of the 
sample gas.
    (iii) You may use a refrigerated-type condenser or similar device 
(e.g., permeation dryer) to remove condensate continuously from sample 
gas while maintaining minimal contact between condensate and sample gas.
    (iv) If your analyzer measures nitric oxide (NO) and nitrogen 
dioxide (NO2) separately, you must use both NO and 
NO2 calibration gases. Otherwise, you must substitute 
NO2 calibration gas for NO calibration gas in the performance 
of system bias checks.
    (v) You must conduct dynamic spiking according to EPA Reference 
Method 7E, section 16.1, of appendix A-4 of this part using 
NO2 as the spike gas.
    (5) Instead of a NOX concentration CEMS meeting 
Performance Specification 2, you may apply an FTIR CEMS meeting the 
requirements of Performance Specification 15 of appendix B of this part 
to measure NOX concentrations. Should you use an FTIR CEMS, 
you must replace the Relative Accuracy Test Audit requirements of 
Procedure 1 of appendix F of this part with the validation requirements 
and criteria of Performance Specification 15, sections 11.1.1 and 12.0, 
of appendix B of this part.
    (c) Determining NOX mass emissions rate values. You must use the 
NOX concentration CEMS, acid production, gas flow rate 
monitor and other monitoring data to calculate emissions data in units 
of the applicable limit (lb NOX/ton of acid produced 
expressed as 100 percent nitric acid).
    (1) You must install, calibrate, maintain, and operate a CEMS for 
measuring and recording the stack gas flow rates to use in combination 
with data from the CEMS for measuring emissions concentrations of 
NOX to produce data in units of mass rate (e.g., lb/hr) of 
NOX on an hourly basis. You will operate and certify the 
continuous emissions rate monitoring system (CERMS) in accordance with 
the provisions of Sec. 60.13 and Performance Specification 6 of 
appendix B of this part. You must comply with the following provisions 
in (c)(1)(i) through (iii) of this section.
    (i) You must use a stack gas flow rate sensor with a full scale 
output of at least 125 percent of the maximum expected exhaust 
volumetric flow rate (see Performance Specification 6, section 8, of 
appendix B of this part).
    (ii) For conducting the relative accuracy test audits, per 
Performance Specification 6, section 8.2 of appendix B of this part and 
Procedure 1, section 5.1.1, of appendix F of this part, you must use 
either EPA Reference Method 2, 2F, or 2G of appendix A-4 of this part. 
You may also apply Method 2H in conjunction with other velocity 
measurements.

[[Page 352]]

    (iii) You must verify that the CERMS complies with the quality 
assurance requirements in Procedure 1 of appendix F of this part. You 
must conduct relative accuracy testing to provide for calculating the 
relative accuracy for RATA and RAA determinations in units of lb/hour.
    (2) You must determine the nitric acid production parameters 
(production rate and concentration) by installing, calibrating, 
maintaining, and operating a permanent monitoring system (e.g., weigh 
scale, volume flow meter, mass flow meter, tank volume) to measure and 
record the weight rates of nitric acid produced in tons per hour. If 
your nitric acid production rate measurements are for periods longer 
than hourly (e.g., daily values), you will determine average hourly 
production values, tons acid/hr, by dividing the total acid production 
by the number of hours of process operation for the subject measurement 
period. You must comply with the following provisions in (c)(2)(i) 
through (iv) of this section.
    (i) You must verify that each component of the monitoring system has 
an accuracy and precision of no more than 5 
percent of full scale.
    (ii) You must analyze product concentration via titration or by 
determining the temperature and specific gravity of the nitric acid. You 
may also use ASTM E1584-11 (incorporated by reference, see Sec. 60.17), 
for determining the concentration of nitric acid in percent. You must 
determine product concentration daily.
    (iii) You must use the acid concentration to express the nitric acid 
production as 100 percent nitric acid.
    (iv) You must record the nitric acid production, expressed as 100 
percent nitric acid, and the hours of operation.
    (3) You must calculate hourly NOX emissions rates in 
units of the standard (lb/ton acid) for each hour of process operation. 
For process operating periods for which there is little or no acid 
production (e.g., startup or shutdown), you must use the average hourly 
acid production rate determined from the data collected over the 
previous 30 days of normal acid production periods (see Sec. 60.75a).
    (d) Continuous monitoring system. For each continuous monitoring 
system, including NOX concentration measurement, volumetric 
flow rate measurement, and nitric acid production measurement equipment, 
you must meet the requirements in paragraphs (d)(1) through (3) of this 
section.
    (1) You must operate the monitoring system and collect data at all 
required intervals at all times the affected facility is operating 
except for periods of monitoring system malfunctions or out-of-control 
periods as defined in appendix F, sections 4 and 5, of this part, 
repairs associated with monitoring system malfunctions or out-of-control 
periods, and required monitoring system quality assurance or quality 
control activities including, as applicable, calibration checks and 
required zero and span adjustments.
    (2) You may not use data recorded during monitoring system 
malfunctions or out-of-control periods, repairs associated with 
monitoring system malfunctions or out-of-control periods, or required 
monitoring system quality assurance or control activities in 
calculations used to report emissions or operating levels. You must use 
all the data collected during all other periods in calculating emissions 
and the status of compliance with the applicable emissions limit in 
accordance with Sec. 60.72a(a).
    (e) Initial performance testing. You must conduct an initial 
performance test to demonstrate compliance with the NOX 
emissions limit under Sec. 60.72a(a) beginning in the calendar month 
following initial certification of the NOX and flow rate 
monitoring CEMS. The initial performance test consists of collection of 
hourly NOX average concentration, mass flow rate recorded 
with the certified NOX concentration and flow rate CEMS and 
the corresponding acid generation (tons) data for all of the hours of 
operation for the first 30 days beginning on the first day of the first 
month following completion of the CEMS installation and certification as 
described above. You must assure that the CERMS meets all of the data 
quality assurance requirements as per Sec. 60.13 and appendix F, 
Procedure 1, of this part and you must use the data from the CERMS for 
this compliance determination.

Sec. 60.74a  Affirmative defense for violations of emission standards during malfunction.

    In response to an action to enforce the standards set forth in Sec. 
60.72a, you may assert an affirmative defense to a claim for civil 
penalties for violations of such standards that are caused by 
malfunction, as defined at 40 CFR 60.2. Appropriate penalties may be 
assessed, however, if you fail to meet your burden of proving all of the 
requirements in the affirmative defense. The affirmative defense shall 
not be available for claims for injunctive relief.
    (a) To establish the affirmative defense in any action to enforce 
such a standard, you must timely meet the reporting requirements in 
paragraph (b) of this section, and must prove by a preponderance of 
evidence that:
    (1) The violation:
    (i) Was caused by a sudden, infrequent, and unavoidable failure of 
air pollution control equipment, process equipment, or a process to 
operate in a normal or usual manner; and
    (ii) Could not have been prevented through careful planning, proper 
design or better operation and maintenance practices; and
    (iii) Did not stem from any activity or event that could have been 
foreseen and avoided, or planned for; and
    (iv) Was not part of a recurring pattern indicative of inadequate 
design, operation, or maintenance; and
    (2) Repairs were made as expeditiously as possible when a violation 
occurred. Off-shift and overtime labor were used, to the extent 
practicable to make these repairs; and
    (3) The frequency, amount, and duration of the violation (including 
any bypass) were minimized to the maximum extent practicable; and
    (4) If the violation resulted from a bypass of control equipment or 
a process, then the bypass was unavoidable to prevent loss of life, 
personal injury, or severe property damage; and
    (5) All possible steps were taken to minimize the impact of the 
violation on ambient air quality, the environment, and human health; and
    (6) All emissions monitoring and control systems were kept in 
operation if at all possible, consistent with safety and good air 
pollution control practices; and
    (7) All of the actions in response to the violation were documented 
by properly signed, contemporaneous operating logs; and
    (8) At all times, the affected facility was operated in a manner 
consistent with good practices for minimizing emissions; and
    (9) A written root cause analysis has been prepared, the purpose of 
which is to determine, correct, and eliminate the primary causes of the 
malfunction and the violation resulting from the malfunction event at 
issue. The analysis shall also specify, using best monitoring methods 
and engineering judgment, the amount of any emissions that were the 
result of the malfunction.
    (b) Report. The owner or operator seeking to assert an affirmative 
defense shall submit a written report to the Administrator with all 
necessary supporting documentation, that it has met the requirements set 
forth in paragraph (a) of this section. This affirmative defense report 
shall be included in the first periodic compliance, deviation report or 
excess emission report otherwise required after the initial occurrence 
of the violation of the relevant standard (which may be the end of any 
applicable averaging period). If such compliance, deviation report or 
excess emission report is due less than 45 days after the initial 
occurrence of the violation, the affirmative defense report may be 
included in the second compliance, deviation report or excess emission 
report due after the initial occurrence of the violation of the relevant 
standard.



Sec. 60.75a  Calculations.

    (a) You must calculate the 30 operating day rolling arithmetic 
average emissions rate in units of the applicable emissions standard (lb 
NOX/ton 100 percent acid produced) at the end of each 
operating day using all of the quality assured hourly average CEMS data 
for the previous 30 operating days.
    (b) You must calculate the 30 operating day average emissions rate 
according to Equation 1:

[[Page 354]]

[GRAPHIC] [TIFF OMITTED] TR06MY14.000

Where:

E30 = 30 operating day average emissions rate of 
          NOX, lb NOX/ton of 100 percent 
          HNO3;
Ci = concentration of NOX for hour i, ppmv;
Qi = volumetric flow rate of effluent gas for hour i, where 
          Ci and Qi are on the same basis (either 
          wet or dry), scf/hr;
Pi = total acid produced during production hour i, tons 100 
          percent HNO3;
k = conversion factor, 1.194 x 10-7 for NOX; and
n = number of operating hours in the 30 operating day period, i.e., n is 
          between 30 and 720.

    (2) Records of actions taken during periods of malfunction to 
minimize emissions in accordance with Sec. 60.11(d), including 
corrective actions to restore malfunctioning process and air pollution 
control and monitoring equipment to its normal or usual manner of 
operation.



Sec. 60.77a  Reporting.

    (a) The performance test data from the initial and subsequent 
performance tests and from the performance evaluations of the continuous 
monitors must be submitted to the Administrator at the appropriate

Sec. 60.81  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A of this part.
    (a) Sulfuric acid production unit means any facility producing 
sulfuric acid by the contact process by burning elemental sulfur, 
alkylation acid, hydrogen sulfide, organic sulfides and mercaptans, or 
acid sludge, but does not include facilities where conversion to

[39 FR 20794, June 14, 1974, as amended at 40 FR 46258, Oct. 6, 1975]



Sec. 60.84  Emission monitoring.

    (a) A continuous monitoring system for the measurement of sulfur 
dioxide shall be installed, calibrated, maintained, and operated by the 
owner or operator. The pollutant gas used to prepare calibration gas 
mixtures under Performance Specification 2 and for calibration checks 
under Sec. 60.13(d), shall be sulfur dioxide (SO2). Method 8 
shall be used for conducting monitoring system performance evaluations 
under Sec. 60.13(c) except that only the sulfur dioxide portion of the 
Method 8 results shall be used. The span value shall be set at 1000 ppm 
of sulfur dioxide.
    (b) The owner or operator shall establish a conversion factor for 
the purpose of converting monitoring data into units of the applicable 
standard (kg/metric ton, lb/ton). The conversion factor shall be 
determined, as a minimum, three times daily by measuring the 
concentration of sulfur dioxide entering the converter using suitable 
methods (e.g., the Reich test, National Air Pollution Control 
Administration Publication No. 999-AP-13) and calculating the 
appropriate conversion factor for each eight-hour period as follows:

CF = k[(1.000-0.015r)/(r-s)]

where:

CF = conversion factor (kg/metric ton per ppm, lb/ton per ppm).
k = constant derived from material balance. For determining CF in metric 
          units, k = 0.0653. For determining CF in English units, k = 
          0.1306.
r = percentage of sulfur dioxide by volume entering the gas converter. 
          Appropriate corrections must be made for air injection plants 
          subject to the Administrator's approval.
s = percentage of sulfur dioxide by volume in the emissions to the 
          atmosphere determined by the continuous monitoring system 
          required under paragraph (a) of this section.

    (c) The owner or operator shall record all conversion factors and 
values under paragraph (b) of this section from which they were computed 
(i.e., CF, r, and s).
    (d) Alternatively, a source that processes elemental sulfur or an 
ore that contains elemental sulfur and uses air to supply oxygen may use 
the following continuous emission monitoring approach and calculation 
procedures in determining SO2 emission rates in terms of the 
standard. This procedure is not required, but is an alternative that 
would alleviate problems encountered in the measurement of gas 
velocities or production rate. Continuous emission monitoring systems 
for measuring SO2, O2, and CO2 (if 
required) shall be installed, calibrated, maintained, and operated by 
the owner or operator and subjected to the certification procedures in 
Performance Specifications 2 and 3. The calibration procedure and span 
value for the SO2 monitor shall be as specified in paragraph 
(b) of this section. The span value for CO2 (if required) 
shall be 10 percent and for O2 shall be 20.9 percent (air). A 
conversion factor based on process rate data is not necessary. Calculate 
the SO2 emission rate as follows:

Es = (Cs S)/[0.265 - (0.0126 %O2) - (A 
%CO2)]

where:

Es = emission rate of SO2, kg/metric ton (lb/ton) 
          of 100 percent of H2SO4 produced.
Cs = concentration of SO2, kg/dscm (lb/dscf).
S = acid production rate factor, 368 dscm/metric ton (11,800 dscf/ton) 
          of 100 percent H2SO4 produced.
%O2 = oxygen concentration, percent dry basis.
A = auxiliary fuel factor,
     = 0.00 for no fuel.
     = 0.0226 for methane.
     = 0.0217 for natural gas.

[[Page 357]]

     = 0.0196 for propane.
     = 0.0172 for No 2 oil.
     = 0.0161 for No 6 oil.
     = 0.0148 for coal.
     = 0.0126 for coke.
%CO2 = carbon dioxide concentration, percent dry basis.

    Note: It is necessary in some cases to convert measured 
concentration units to other units for these calculations:

Use the following table for such conversions:

------------------------------------------------------------------------
              From--                        To--           Multiply by--
------------------------------------------------------------------------
g/scm.............................  kg/scm..............            10-3
mg/scm............................  kg/scm..............            10-6
ppm (SO2).........................  kg/scm..............    2.660 x 10-6
ppm (SO2).........................  lb/scf..............    1.660 x 10-7
------------------------------------------------------------------------

    (e) For the purpose of reports under Sec. 60.7(c), periods of 
excess emissions shall be all three-hour periods (or the arithmetic 
average of three consecutive one-hour periods) during which the 
integrated average sulfur dioxide emissions exceed the applicable 
standards under Sec. 60.82.

Sec. 60.85  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b). 
Acceptable alternative methods and procedures are given in paragraph (c)

facility including periods of startup, shutdown, or malfunction, except 
for continuous monitoring system breakdowns, repairs, calibration 
checks, and zero and span adjustments.
    (12) The owner or operator shall use the following procedures to 
evaluate the continuous monitoring systems under paragraphs (a)(8), 
(a)(9), and (a)(10) of this section.
    (i) Method 3 or 3A and Method 6 or 6C for the relative accuracy 
evaluations under the Sec. 60.13(e) performance evaluation.
    (ii) Appendix F, Procedure 1, including quarterly accuracy 
determinations and daily calibration drift tests.
    (13) When seeking to comply with Sec. 60.104(b)(1), when emission 
data are not obtained because of continuous monitoring system 
breakdowns, repairs, calibration checks and zero and span adjustments, 
emission data will be obtained by using one of the following methods to 
provide emission data for a minimum of 18 hours per day in at least 22 
out of 30 rolling successive calendar days.
    (i) The test methods as described in Sec. 60.106(k);
    (ii) A spare continuous monitoring system; or
    (iii) Other monitoring systems as approved by the Administrator.
    (b) An owner or operator may demonstrate that a fuel gas stream 
combusted in a fuel gas combustion device subject to Sec. 60.104(a)(1) 
that is not specifically exempted in Sec. 60.105(a)(4)(iv) is 
inherently low in sulfur. A fuel gas stream that is determined to be 
low-sulfur is exempt from the monitoring requirements in paragraphs 
(a)(3) and (4) of this section until there are changes in operating 
conditions or stream composition.
    (1) The owner or operator shall submit to the Administrator a 
written application for an exemption from monitoring. The application 
must contain the following information:
    (i) A description of the fuel gas stream/system to be considered, 
including submission of a portion of the appropriate piping diagrams 
indicating the boundaries of the fuel gas stream/system, and the 
affected fuel gas combustion device(s) to be considered;
    (ii) A statement that there are no crossover or entry points for 
sour gas (high H2S content) to be introduced into the fuel 
gas stream/system (this should be shown in the piping diagrams);
    (iii) An explanation of the conditions that ensure low amounts of 
sulfur in the fuel gas stream (i.e., control equipment or product 
specifications) at all times;
    (iv) The supporting test results from sampling the requested fuel 
gas stream/system demonstrating that the sulfur content is less than 5 
ppmv. Sampling data must include, at minimum, 2 weeks of daily 
monitoring (14 grab samples) for frequently operated fuel gas streams/
systems; for infrequently operated fuel gas streams/systems, seven grab 
samples must be collected unless other additional information would 
support reduced sampling. The owner or operator shall use detector tubes 
(``length-of-stain tube'' type measurement) following the ``Gas 
Processors Association Standard 2377-86 (incorporated by reference--see 
Sec. 60.17), using tubes with a maximum span between 10 and 40 ppmv 
inclusive when 1<=N<=10, where N = number of pump strokes, to test the 
applicant fuel gas stream for H2S; and
    (v) A description of how the 2 weeks (or seven samples for 
infrequently operated fuel gas streams/systems) of monitoring results 
compares to the typical range of H2S concentration (fuel 
quality) expected for the fuel gas stream/system going to the affected 
fuel gas combustion device (e.g., the 2 weeks of daily detector tube 
results for a frequently operated loading rack included the entire range 
of products loaded out, and, therefore, should be representative of 
typical operating conditions affecting H2S content in the 
fuel gas stream going to the loading rack flare).
    (2) The effective date of the exemption is the date of submission of 
the information required in paragraph (b)(1) of this section).
    (3) No further action is required unless refinery operating 
conditions change in such a way that affects the exempt fuel gas stream/
system (e.g.,

[[Page 365]]

the stream composition changes). If such a change occurs, the owner or 
operator will follow the procedures in paragraph (b)(3)(i), (b)(3)(ii), 
or (b)(3)(iii) of this section.
    (i) If the operation change results in a sulfur content that is 
still within the range of concentrations included in the original 
application, the owner or operator shall conduct an H2S test 
on a grab sample and record the results as proof that the concentration 
is still within the range.
    (ii) If the operation change results in a sulfur content that is 
outside the range of concentrations included in the original 
application, the owner or operator may submit new information following 
the procedures of paragraph (b)(1) of this section within 60 days (or 
within 30 days after the seventh grab sample is tested for infrequently 
operated process units).
    (iii) If the operation change results in a sulfur content that is 
outside the range of concentrations included in the original application 
and the owner or operator chooses not to submit new information to 
support an exemption, the owner or operator must begin H2S 
monitoring using daily stain sampling to demonstrate compliance using 
length-of stain tubes with a maximum span between 200 and 400 ppmv 
inclusive when 1<=N<=5, where N = number of pump strokes. The owner or 
operator must begin monitoring according to the requirements in 
paragraph (a)(1) or (2) of this section as soon as practicable but in no 
case later than 180 days after the operation change. During daily stain 
tube sampling, a daily sample exceeding 162 ppmv is an exceedance of the 
3-hour H2S concentration limit.
    (c) The average coke burn-off rate (Mg (tons) per hour) and hours of 
operation shall be recorded daily for any fluid catalytic cracking unit 
catalyst regenerator subject to Sec. 60.102, Sec. 60.103, or Sec. 
60.104(b)(2).
    (d) For any fluid catalytic cracking unit catalyst regenerator under 
Sec. 60.102 that uses an incinerator-waste heat boiler to combust the 
exhaust gases from the catalyst regenerator, the owner or operator shall 
record daily the rate of combustion of liquid or solid fossil-fuels and 
the hours of operation during which liquid or solid fossil-fuels are 
combusted in the incinerator-waste heat boiler.
    (e) For the purpose of reports under Sec. 60.7(c), periods of 
excess emissions that shall be determined and reported are defined as 
follows:

    Note: All averages, except for opacity, shall be determined as the 
arithmetic average of the applicable 1-hour averages, e.g., the rolling 
3-hour average shall be determined as the arithmetic average of three 
contiguous 1-hour averages.

    (1) Opacity. All 1-hour periods that contain two or more 6-minute 
periods during which the average opacity as measured by the continuous 
monitoring system under Sec. 60.105(a)(1) exceeds 30 percent.
    (2) Carbon monoxide. All 1-hour periods during which the average CO 
concentration as measured by the CO continuous monitoring system under 
Sec. 60.105(a)(2) exceeds 500 ppm.
    (3) Sulfur dioxide from fuel gas combustion. (i) All rolling 3-hour 
periods during which the average concentration of SO2 as 
measured by the SO2 continuous monitoring system under Sec. 
60.105(a)(3) exceeds 20 ppm (dry basis, zero percent excess air); or
    (ii) All rolling 3-hour periods during which the average 
concentration of H2S as measured by the H2S 
continuous monitoring system under Sec. 60.105(a)(4) exceeds 230 mg/
dscm (0.10 gr/dscf).
    (4) Sulfur dioxide from Claus sulfur recovery plants. (i) All 12-
hour periods during which the average concentration of SO2 as 
measured by the SO2 continuous monitoring system under Sec. 
60.105(a)(5) exceeds 250 ppm (dry basis, zero percent excess air); or
    (ii) All 12-hour periods during which the average concentration of 
reduced sulfur (as SO2) as measured by the reduced sulfur 
continuous monitoring system under Sec. 60.105(a)(6) exceeds 300 ppm; 
or
    (iii) All 12-hour periods during which the average concentration of 
SO2 as

[[Page 366]]

measured by the SO2 continuous monitoring system under Sec. 
60.105(a)(7) exceeds 250 ppm (dry basis, zero percent excess air).

Sec. 60.106  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter (PM) standards in Sec. 60.102(a) as follows:
    (1) The emission rate (E) of PM shall be computed for each run using

          hr).
Rc = Coke burn-off rate, Mg/hr (ton/hr) coke.
K = Conversion factor, 1,000 g/kg (7,000 gr/lb).

    (2) Method 5B or 5F is to be used to determine particulate matter 
emissions and associated moisture content from affected facilities 
without wet FGD systems; only Method 5B is to be used after wet FGD 
systems. The sampling time for each run shall be at least 60 minutes and 
the sampling rate shall be at least 0.015 dscm/min (0.53 dscf/min), 
except that shorter sampling times may be approved by the Administrator 
when process variables or other factors preclude sampling for at least 
60 minutes.
    (3) The coke burn-off rate (Rc) shall be computed for 
each run using the following equation:

 Rc = K1Qr (%CO2 + %CO) + 
K2Qa-K3Qr (%CO/2 + 
%CO2 + %O2) + K3Qoxy 
(%Ooxy)

Where:

Rc = Coke burn-off rate, kilograms per hour (kg/hr) (lb/hr).
Qr = Volumetric flow rate of exhaust gas from fluid catalytic 
          cracking unit regenerator before entering the emission control 
          system, dscm/min (dscf/min).

          basis).
%CO = CO concentration in FCCU regenerator exhaust, percent by volume 
          (dry basis).
%O2 = O2 concentration in fluid catalytic cracking 
          unit regenerator exhaust, percent by volume (dry basis).
%Ooxy = O2 concentration in O2 enriched 
          air stream inlet to the fluid catalytic cracking unit 
          regenerator, percent by volume (dry basis).
K1 = Material balance and conversion factor, 0.2982 (kg-min)/
          (hr-dscm-%) [0.0186 (lb-min)/(hr-dscf-%)].

          (hr-dscm) [0.1303 (lb-min)/(hr-dscf)].
K3 = Material balance and conversion factor, 0.0994 (kg-min)/
          (hr-dscm-%) [0.00624 (lb-min)/(hr-dscf-%)].

(Qr).
    (ii) The emission correction factor, integrated sampling and 
analysis procedure of Method 3B shall be used to determine 
CO2, CO, and O2 concentrations.
    (4) Method 9 and the procedures of Sec. 60.11 shall be used to 
determine opacity.
    (c) If auxiliary liquid or solid fossil-fuels are burned in an 
incinerator-waste heat boiler, the owner or operator shall determine the 
emission rate of PM permitted in Sec. 60.102(b) as follows:
    (1) The allowable emission rate (Es) of PM shall be 
computed for each run using the following equation:

Es = F + A (H/Rc)


[[Page 367]]


Where:

Es = Emission rate of PM allowed, kg/Mg (lb/ton) of coke 
          burn-off in catalyst regenerator.
F = Emission standard, 1.0 kg/Mg (2.0 lb/ton) of coke burn-off in 
          catalyst regenerator.
A = Allowable incremental rate of PM emissions, 43 g/GJ (0.10 lb/million 
          Btu).

          Btu/hr).
Rc = Coke burn-off rate, Mg coke/hr (ton coke/hr).

    (2) Procedures subject to the approval of the Administrator shall be 
used to determine the heat input rate.
    (3) The procedure in paragraph (b)(3) of this section shall be used 
to determine the coke burn-off rate (Rc).
    (d) The owner or operator shall determine compliance with the CO 
standard in Sec. 60.103(a) by using the integrated sampling technique 
of Method 10 to determine the CO concentration (dry basis). The sampling 
time for each run shall be 60 minutes.
    (e)(1) The owner or operator shall determine compliance with the 
H2S standard in Sec. 60.104(a)(1) as follows: Method 11, 15, 
15A, or 16 shall be used to determine the H2S concentration. 
The gases entering the sampling train should be at about atmospheric 
pressure. If the pressure in the refinery fuel gas lines is relatively 
high, a flow control valve may be used to reduce the pressure. If the 
line pressure is high enough to operate the sampling train without a 
vacuum pump, the pump may be eliminated from the sampling train. The 
sample shall be drawn from a point near the centroid of the fuel gas 
line.
    (i) For Method 11, the sampling time and sample volume shall be at 
least 10 minutes and 0.010 dscm (0.35 dscf). Two samples of equal 
sampling times shall be taken at about 1-hour intervals. The arithmetic 
average of these two samples shall constitute a run. For most fuel 
gases, sampling times exceeding 20 minutes may result in depletion of 
the collection solution, although fuel gases containing low 
concentrations of H2S may necessitate sampling for longer 
periods of time.
    (ii) For Method 15 or 16, at least three injects over a 1-hour 
period shall constitute a run.
    (iii) For Method 15A, a 1-hour sample shall constitute a run.
    (2) Where emissions are monitored by Sec. 60.105(a)(3), compliance 
with Sec. 60.104(a)(1) shall be determined using Method 6 or 6C and 
Method 3 or 3A. The method ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust 
Gas Analyses,'' (incorporated by reference--see Sec. 60.17) is an 
acceptable alternative to EPA Method 6. A 1-hour sample shall constitute 
a run. Method 6 samples shall be taken at a rate of approximately 2 
liters/min. The ppm correction factor (Method 6) and the sampling 
location in paragraph (f)(1) of this section apply. Method 4 shall be 
used to determine the moisture content of the gases. The sampling point 
for Method 4 shall be adjacent to the sampling point for Method 6 or 6C.
    (f) The owner or operator shall determine compliance with the 
SO2 and the H2S and reduced sulfur standards in 
Sec. 60.104(a)(2) as follows:
    (1) Method 6 shall be used to determine the SO2 
concentration. The concentration in mg/dscm obtained by Method 6 or 6C 
is multiplied by 0.3754 to obtain the concentration in ppm. The sampling 
point in the duct shall be the centroid of the cross section if the 
cross-sectional area is less than 5.00 m\2\ (53.8 ft\2\) or at a point 
no closer to the walls than 1.00 m (39.4 in.) if the cross-sectional 
area is 5.00 m\2\ or more and the centroid is more than 1 m from the 
wall. The sampling time and sample volume shall be at least 10 minutes 
and 0.010 dscm (0.35 dscf) for each sample. Eight samples of equal 
sampling times shall be taken at about 30-minute intervals. The 
arithmetic average of these eight samples shall constitute a run. For 
Method 6C, a run shall consist of the arithmetic average of four 1-hour 
samples. Method 4 shall be used to determine the moisture content of the 
gases. The sampling point for Method 4 shall be adjacent to the sampling 
point for Method 6 or 6C. The sampling time for each sample shall be 
equal to the time it takes for two Method 6 samples. The moisture 
content from this sample shall be used to correct the corresponding 
Method 6 samples for moisture. For documenting the oxidation efficiency 
of the control device for reduced sulfur compounds, Method 15 shall be 
used following the procedures of paragraph (f)(2) of this section.

[[Page 368]]

    (2) Method 15 shall be used to determine the reduced sulfur and 
H2 S concentrations. Each run shall consist of 16 samples 
taken over a minimum of 3 hours. The sampling point shall be the same as 
that described for Method 6 in paragraph (f)(1) of this section. To 
ensure minimum residence time for the sample inside the sample lines, 
the sampling rate shall be at least 3.0 lpm (0.10 cfm). The 
SO2 equivalent for each run shall be calculated after being 
corrected for moisture and oxygen as the arithmetic average of the 
SO2 equivalent for each sample during the run. Method 4 shall 
be used to determine the moisture content of the gases as the paragraph 
(f)(1) of this section. The sampling time for each sample shall be equal 
to the time it takes for four Method 15 samples.
    (3) The oxygen concentration used to correct the emission rate for 
excess air shall be obtained by the integrated sampling and analysis 
procedure of Method 3 or 3A. The samples shall be taken simultaneously 
with the SO2, reduced sulfur and H2S, or moisture 
samples. The SO2, reduced sulfur, and H2S samples 
shall be corrected to zero percent excess air using the equation in 
paragraph (h)(6) of this section.
    (g) Each performance test conducted for the purpose of determining 
compliance under Sec. 60.104(b) shall consist of all testing performed 
over a 7-day period using Method 6 or 6C and Method 3 or 3A. To 
determine compliance, the arithmetic mean of the results of all the 
tests shall be compared with the applicable standard.
    (h) For the purpose of determining compliance with Sec. 
60.104(b)(1), the following calculation procedures shall be used:
    (1) Calculate each 1-hour average concentration (dry, zero percent 
oxygen, ppmv) of sulfur dioxide at both the inlet and the outlet to the 
add-on control device as specified in Sec. 60.13(h). These calculations 
are made using the emission data collected under Sec. 60.105(a).
    (2) Calculate a 7-day average (arithmetic mean) concentration of 
sulfur dioxide for the inlet and for the outlet to the add-on control 
device using all of the 1-hour average concentration values obtained 
during seven successive 24-hour periods.
    (3) Calculate the 7-day average percent reduction using the 
following equation:

Rso2 = 100(Cso2(i) - Cso2(o)) / 
Cso2(i)

where:

Rso2 = 7-day average sulfur dioxide emission reduction, 
          percent
Cso2(i) = sulfur dioxide emission concentration determined in 
          Sec. 60.106(h)(2) at the inlet to the add-on control device, 
          ppmv
Cso2(o) = sulfur dioxide emission concentration determined in 
          Sec. 60.106(h)(2) at the outlet to the add-on control device, 
          ppmv
100 = conversion factor, decimal to percent

    (4) Outlet concentrations of sulfur dioxide from the add-on control 
device for compliance with the 50 ppmv standard, reported on a dry, 
O2-free basis, shall be calculated using the procedures 
outlined in Sec. 60.106(h)(1) and (2) above, but for the outlet monitor 
only.
    (5) If supplemental sampling data are used for determining the 7-day 
averages under paragraph (h) of this section and such data are not 
hourly averages, then the value obtained for each supplemental sample 
shall be assumed to represent the hourly average for each hour over 
which the sample was obtained.
    (6) For the purpose of adjusting pollutant concentrations to zero 
percent oxygen, the following equation shall be used:

Cadj = Cmeas[20.9c/(20.9-
%O2)]

where:

Cadj = pollutant concentration adjusted to zero percent 
          oxygen, ppm or g/dscm
Cmeas = pollutant concentration measured on a dry basis, ppm 
          or g/dscm
20.9c = 20.9 percent oxygen-0.0 percent oxygen (defined 
          oxygen correction basis), percent
20.9 = oxygen concentration in air, percent
%O2 = oxygen concentration measured on a dry basis, percent

    (i) For the purpose of determining compliance with Sec. 
60.104(b)(2), the following reference methods and calculation procedures 
shall be used except as provided in paragraph (i)(12) of this section:
    (1) One 3-hour test shall be performed each day.

[[Page 369]]

    (2) For gases released to the atmosphere from the fluid catalytic 
cracking unit catalyst regenerator:
    (i) Method 8 as modified in Sec. 60.106(i)(3) for moisture content 
and for the concentration of sulfur oxides calculated as sulfur dioxide,
    (ii) Method 1 for sample and velocity traverses,
    (iii) Method 2 calculation procedures (data obtained from Methods 3 
and 8) for velocity and volumetric flow rate, and
    (iv) Method 3 for gas analysis.
    (3) Method 8 shall be modified by the insertion of a heated glass 
fiber filter between the probe and first impinger. The probe liner and 
glass fiber filter temperature shall be maintained above 160 [deg]C (320 
[deg]F). The isopropanol impinger shall be eliminated. Sample recovery 
procedures described in Method 8 for container No. 1 shall be 
eliminated. The heated glass fiber filter also shall be excluded; 
however, rinsing of all connecting glassware after the heated glass 
fiber filter shall be retained and included in container No. 2. Sampled 
volume shall be at least 1 dscm.
    (4) For Method 3, the integrated sampling technique shall be used.
    (5) Sampling time for each run shall be at least 3 hours.
    (6) All testing shall be performed at the same location. Where the 
gases discharged by the fluid catalytic cracking unit catalyst 
regenerator pass through an incinerator-waste heat boiler in which 
auxiliary or supplemental gaseous, liquid, or solid fossil fuel is 
burned, testing shall be conducted at a point between the regenerator 
outlet and the incinerator-waste heat boiler. An alternative sampling 
location after the waste heat boiler may be used if alternative coke 
burn-off rate equations, and, if requested, auxiliary/supplemental fuel 
SOX credits, have been submitted to and approved by the 
Administrator prior to sampling.
    (7) Coke burn-off rate shall be determined using the procedures 
specified under paragraph (b)(3) of this section, unless paragraph 
(i)(6) of this section applies.
    (8) Calculate the concentration of sulfur oxides as sulfur dioxide 
using equation 8-3 in Section 6.5 of Method 8 to calculate and report 
the total concentration of sulfur oxides as sulfur dioxide (Cso 
x).
    (9) Sulfur oxides emission rate calculated as sulfur dioxide shall 
be determined for each test run by the following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.003

Where:

ESOx = sulfur oxides emission rate calculated as sulfur 
          dioxide, kg/hr (lb/hr)
CSOx = sulfur oxides emission concentration calculated as 
          sulfur dioxide, g/dscm (gr/dscf)
Qsd = dry volumetric stack gas flow rate corrected to 
          standard conditions, dscm/hr (dscf/hr)
K = 1,000 g/kg (7,000 gr/lb)

    (10) Sulfur oxides emissions calculated as sulfur dioxide shall be 
determined for each test run by the following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.004

Where:

RSOx = Sulfur oxides emissions calculated as kg sulfur 
          dioxide per Mg (lb/ton) coke burn-off.
ESOx = Sulfur oxides emission rate calculated as sulfur 
          dioxide, kg/hr (lb/hr).
Rc = Coke burn-off rate, Mg/hr (ton/hr).

    (11) Calculate the 7-day average sulfur oxides emission rate as 
sulfur dioxide per Mg (ton) of coke burn-off by dividing the sum of the 
individual daily rates by the number of daily rates summed.
    (12) An owner or operator may, upon approval by the Administrator, 
use an alternative method for determining compliance with Sec. 
60.104(b)(2), as provided in Sec. 60.8(b). Any requests for approval 
must include data to demonstrate to the Administrator that the 
alternative method would produce results adequate for the determination 
of compliance.
    (j) For the purpose of determining compliance with Sec. 
60.104(b)(3), the following analytical methods and calculation 
procedures shall be used:
    (1) One fresh feed sample shall be collected once per 8-hour period.
    (2) Fresh feed samples shall be analyzed separately by using any one 
of the following applicable analytical test methods: ASTM D129-64, 78, 
or 95,

[[Page 370]]

ASTM D1552-83 or 95, ASTM D2622-87, 94, or 98, or ASTM D1266-87, 91, or 
98. (These methods are incorporated by reference: see Sec. 60.17.) The 
applicable range of some of these ASTM methods is not adequate to 
measure the levels of sulfur in some fresh feed samples. Dilution of 
samples prior to analysis with verification of the dilution ratio is 
acceptable upon prior approval of the Administrator.
    (3) If a fresh feed sample cannot be collected at a single location, 
then the fresh feed sulfur content shall be determined as follows:
    (i) Individual samples shall be collected once per 8-hour period for 
each separate fresh feed stream charged directly into the riser or 
reactor of the fluid catalytic cracking unit. For each sample location 
the fresh feed volumetric flow rate at the time of collecting the fresh 
feed sample shall be measured and recorded. The same method for 
measuring volumetric flow rate shall be used at all locations.
    (ii) Each fresh feed sample shall be analyzed separately using the 
methods specified under paragraph (j)(2) of this section.
    (iii) Fresh feed sulfur content shall be calculated for each 8-hour 
period using the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.005

where:

Sf = fresh feed sulfur content expressed in percent by weight 
          of fresh feed.
n = number of separate fresh feed streams charged directly to the riser 
          or reactor of the fluid catalytic cracking unit.
Qf = total volumetric flow rate of fresh feed charged to the 
          fluid catalytic cracking unit.
Si = fresh feed sulfur content expressed in percent by weight 
          of fresh feed for the ``ith'' sampling location.
Qi = volumetric flow rate of fresh feed stream for the 
          ``ith'' sampling location.

    (4) Calculate a 7-day average (arithmetic mean) sulfur content of 
the fresh feed using all of the fresh feed sulfur content values 
obtained during seven successive 24-hour periods.
    (k) The test methods used to supplement continuous monitoring system 
data to meet the minimum data requirements in Sec. 60.104(d) will be 
used as described below or as otherwise approved by the Administrator.
    (1) Methods 6, 6B, or 8 are used. The sampling location(s) are the 
same as those specified for the monitor.
    (2) For Method 6, the minimum sampling time is 20 minutes and the 
minimum sampling volume is 0.02 dscm (0.71 dscf) for each sample. 
Samples are taken at approximately 60-minute intervals. Each sample 
represents a 1-hour average. A minimum of 18 valid samples is required 
to obtain one valid day of data.
    (3) For Method 6B, collection of a sample representing a minimum of 
18 hours is required to obtain one valid day of data.
    (4) For Method 8, the procedures as outlined in this section are 
used. The equivalent of 16 hours of sampling is required to obtain one 
valid day of data.

subpart J of this part. For flares, the provisions of this subpart apply 
only to flares which commence construction, modification or 
reconstruction after June 24, 2008. For the purposes of this subpart, a 
modification to a flare commences when a project that includes any of 
the activities in paragraphs (c)(1) or (2) of this section is commenced. 
For delayed coking units, the provisions of this subpart apply to 
delayed coking units that commence construction, reconstruction or 
modification on the earliest of the following dates:
    (1) May 14, 2007, for such activities that involve a ``delayed 
coking unit'' defined as follows: one or more refinery process units in

Sec. 60.14 regarding modification apply. As provided in Sec. 60.14(f), 
the special provisions set forth under this subpart shall supersede the 
provisions in Sec. 60.14 with respect to flares. For the purposes of 
this subpart, a modification to a flare occurs as provided in paragraphs 
(c)(1) or (2) of this section.
    (1) Any new piping from a refinery process unit, including ancillary 
equipment, or a fuel gas system is physically connected to the flare 
(e.g., for direct emergency relief or some form of continuous or 
intermittent venting). However, the connections described in paragraphs 
(c)(1)(i) through (vii) of this section are not considered modifications 
of a flare.
    (i) Connections made to install monitoring systems to the flare.
    (ii) Connections made to install a flare gas recovery system or 
connections made to upgrade or enhance components of a flare gas 
recovery system (e.g., addition of compressors or recycle lines).
    (iii) Connections made to replace or upgrade existing pressure 
relief or safety valves, provided the new pressure relief or safety 
valve has a set point opening pressure no lower and an internal diameter 
no greater than the existing equipment being replaced or upgraded.
    (iv) Connections made for flare gas sulfur removal.

[[Page 374]]

    (v) Connections made to install back-up (redundant) equipment 
associated with the flare (such as a back-up compressor) that does not 
increase the capacity of the flare.
    (vi) Replacing piping or moving an existing connection from a 
refinery process unit to a new location in the same flare, provided the 
new pipe diameter is less than or equal to the diameter of the pipe/
connection being replaced/moved.
    (vii) Connections that interconnect two or more flares.
    (2) A flare is physically altered to increase the flow capacity of 
the flare.
    (d) For purposes of this subpart, under Sec. 60.15, the ``fixed 
capital cost of the new components'' includes the fixed capital cost of 
all depreciable components which are or will be replaced pursuant to all 
continuous programs of component replacement which are commenced within 
any 2-year period following the relevant applicability date specified in 
paragraph (b) of this section.

Sec. 60.101a  Definitions.

    Terms used in this subpart are defined in the Clean Air Act (CAA), 
in Sec. 60.2 and in this section.
    Air preheat means a device used to heat the air supplied to a 
process heater generally by use of a heat exchanger to recover the 
sensible heat of exhaust gas from the process heater.
    Ancillary equipment means equipment used in conjunction with or that 
serve a refinery process unit. Ancillary equipment includes, but is not 
limited to, storage tanks, product loading operations, wastewater 
treatment systems, steam- or electricity-producing units (including coke 
gasification units), pressure relief valves, pumps, sampling vents and 
continuous analyzer vents.
    Cascaded flare system means a series of flares connected to one 
flare gas header system arranged with increasing pressure set points so 
that discharges will be initially directed to the first flare in the 
series (i.e., the primary flare). If the discharge pressure exceeds a 
set point at which the flow to the primary flare would exceed the 
primary flare's capacity, flow will be diverted to the second flare in 
the series. Similarly, flow would be diverted to a third (or fourth) 
flare if the pressure in the flare gas header system exceeds a threshold 
where the flow to the first two (or three) flares would exceed their 
capacities.
    Co-fired process heater means a process heater that employs burners 
that are designed to be supplied by both gaseous and liquid fuels on a 
routine basis. Process heaters that have gas burners with emergency oil 
back-up burners are not considered co-fired process heaters.
    Coke burn-off means the coke removed from the surface of the FCCU 
catalyst by combustion in the catalyst regenerator. The rate of coke 
burn-off is calculated by the formula specified in Sec. 60.104a.
    Contact material means any substance formulated to remove metals, 
sulfur, nitrogen, or any other contaminant from petroleum derivatives.
    Corrective action means the design, operation and maintenance 
changes that one takes consistent with good engineering practice to 
reduce or eliminate the likelihood of the recurrence of the primary 
cause and any other contributing cause(s) of an event identified by a 
root cause analysis as having resulted in a discharge of gases from an 
affected facility in excess of specified thresholds.
    Corrective action analysis means a description of all reasonable 
interim and long-term measures, if any, that are available, and an 
explanation of why the selected corrective action(s) is/are the best 
alternative(s), including, but not limited to, considerations of cost 
effectiveness, technical feasibility, safety and secondary impacts.
    Delayed coking unit means a refinery process unit in which high 
molecular weight petroleum derivatives are thermally cracked and 
petroleum coke is produced in a series of closed, batch system reactors. 
A delayed coking unit includes, but is not limited to, all of the coke 
drums associated with a single fractionator; the fractionator, including 
the bottoms receiver and the overhead condenser; the coke drum cutting 
water and quench system, including the jet pump and coker quench

[[Page 375]]

water tank; and the coke drum blowdown recovery compressor system.
    Emergency flare means a flare that combusts gas exclusively released 
as a result of malfunctions (and not startup, shutdown, routine 
operations or any other cause) on four or fewer occasions in a rolling 
365-day period. For purposes of this rule, a flare cannot be categorized 
as an emergency flare unless it maintains a water seal.
    Flare means a combustion device that uses an uncontrolled volume of 
air to burn gases. The flare includes the foundation, flare tip, 
structural support, burner, igniter, flare controls, including air 
injection or steam injection systems, flame arrestors and the flare gas 
header system. In the case of an interconnected flare gas header system, 
the flare includes each individual flare serviced by the interconnected 
flare gas header system and the interconnected flare gas header system.
    Flare gas header system means all piping and knockout pots, 
including those in a subheader system, used to collect and transport gas 
to a flare either from a process unit or a pressure relief valve from 
the fuel gas system, regardless of whether or not a flare gas recovery 
system draws gas from the flare gas header system. The flare gas header 
system includes piping inside the battery limit of a process unit if the 
purpose of the piping is to transport gas to a flare or knockout pot 
that is part of the flare.
    Flare gas recovery system means a system of one or more compressors, 
piping and the associated water seal, rupture disk or similar device 
used to divert gas from the flare and direct the gas to the fuel gas 
system or to a fuel gas combustion device.
    Flexicoking unit means a refinery process unit in which high 
molecular weight petroleum derivatives are thermally cracked and 
petroleum coke is continuously produced and then gasified to produce a 
synthetic fuel gas.
    Fluid catalytic cracking unit means a refinery process unit in which 
petroleum derivatives are continuously charged and hydrocarbon molecules 
in the presence of a catalyst suspended in a fluidized bed are fractured 
into smaller molecules, or react with a contact material suspended in a 
fluidized bed to improve feedstock quality for additional processing and 
the catalyst or contact material is continuously regenerated by burning 
off coke and other deposits. The unit includes the riser, reactor, 
regenerator, air blowers, spent catalyst or contact material stripper, 
catalyst or contact material recovery equipment, and regenerator 
equipment for controlling air pollutant emissions and for heat recovery. 
When fluid catalyst cracking unit regenerator exhaust from two separate 
fluid catalytic cracking units share a common exhaust treatment (e.g., 
CO boiler or wet scrubber), the fluid catalytic cracking unit is a 
single affected facility.
    Fluid coking unit means a refinery process unit in which high 
molecular weight petroleum derivatives are thermally cracked and 
petroleum coke is continuously produced in a fluidized bed system. The 
fluid coking unit includes the coking reactor, the coking burner, and 
equipment for controlling air pollutant emissions and for heat recovery 
on the fluid coking burner exhaust vent.
    Forced draft process heater means a process heater in which the 
combustion air is supplied under positive pressure produced by a fan at 
any location in the inlet air line prior to the point where the 
combustion air enters the process heater or air preheat. For the 
purposes of this subpart, a process heater that uses fans at both the 
inlet air side and the exhaust air side (i.e., balanced draft system) is 
considered to be a forced draft process heater.
    Fuel gas means any gas which is generated at a petroleum refinery 
and which is combusted. Fuel gas includes natural gas when the natural 
gas is combined and combusted in any proportion with a gas generated at 
a refinery. Fuel gas does not include gases generated by catalytic 
cracking unit catalyst regenerators, coke calciners (used to make 
premium grade coke) and fluid coking burners, but does include gases 
from flexicoking unit gasifiers and other gasifiers. Fuel gas does not 
include vapors that are collected and combusted in a thermal oxidizer or 
flare installed to control emissions from wastewater treatment units 
other than those processing sour water, marine tank vessel loading 
operations or

[[Page 376]]

asphalt processing units (i.e., asphalt blowing stills).
    Fuel gas combustion device means any equipment, such as process 
heaters and boilers, used to combust fuel gas. For the purposes of this 
subpart, fuel gas combustion device does not include flares or 
facilities in which gases are combusted to produce sulfur or sulfuric 
acid.
    Fuel gas system means a system of compressors, piping, knock-out 
pots, mix drums, and units used to remove sulfur contaminants from the 
fuel gas (e.g., amine scrubbers) that collects refinery fuel gas from 
one or more sources for treatment as necessary prior to combusting in 
process heaters or boilers. A fuel gas system may have an overpressure 
vent to a flare but the primary purpose for a fuel gas system is to 
provide fuel to the refinery.
    Natural draft process heater means any process heater in which the 
combustion air is supplied under ambient or negative pressure without 
the use of an inlet air (forced draft) fan. For the purposes of this 
subpart, a natural draft process heater is any process heater that is 
not a forced draft process heater, including induced draft systems.
    Non-emergency flare means any flare that is not an emergency flare 
as defined in this subpart.
    Oxidation control system means an emission control system which 
reduces emissions from sulfur recovery plants by converting these 
emissions to sulfur dioxide (SO2) and recycling the 
SO2 to the reactor furnace or the first-stage catalytic 
reactor of the Claus sulfur recovery plant or converting the 
SO2 to a sulfur product.
    Petroleum means the crude oil removed from the earth and the oils 
derived from tar sands, shale, and coal.
    Petroleum refinery means any facility engaged in producing gasoline, 
kerosene, distillate fuel oils, residual fuel oils, lubricants, asphalt 
(bitumen) or other products through distillation of petroleum or through 
redistillation, cracking or reforming of unfinished petroleum 
derivatives. A facility that produces only oil shale or tar sands-
derived crude oil for further processing at a petroleum refinery using 
only solvent extraction and/or distillation to recover diluent is not a 
petroleum refinery.
    Primary flare means the first flare in a cascaded flare system.
    Process heater means an enclosed combustion device used to transfer 
heat indirectly to process stream materials (liquids, gases, or solids) 
or to a heat transfer material for use in a process unit instead of 
steam.
    Process upset gas means any gas generated by a petroleum refinery 
process unit or by ancillary equipment as a result of startup, shutdown, 
upset or malfunction.
    Purge gas means gas introduced between a flare's water seal and a 
flare's tip to prevent oxygen infiltration (backflow) into the flare 
tip. For flares with no water seals, the function of purge gas is 
performed by sweep gas (i.e., flares without water seals do not use 
purge gas).
    Reduced sulfur compounds means hydrogen sulfide (H2S), 
carbonyl sulfide, and carbon disulfide.
    Reduction control system means an emission control system which 
reduces emissions from sulfur recovery plants by converting these 
emissions to H2S and either recycling the H2S to 
the reactor furnace or the first-stage catalytic reactor of the Claus 
sulfur recovery plant or converting the H2S to a sulfur 
product.
    Refinery process unit means any segment of the petroleum refinery in 
which a specific processing operation is conducted.
    Root cause analysis means an assessment conducted through a process 
of investigation to determine the primary cause, and any other 
contributing cause(s), of a discharge of gases in excess of specified 
thresholds.
    Secondary flare means a flare in a cascaded flare system that 
provides additional flare capacity and pressure relief to a flare gas 
system when the flare gas flow exceeds the capacity of the primary 
flare. For purposes of this subpart, a secondary flare is characterized 
by infrequent use and must maintain a water seal.
    Sour water means water that contains sulfur compounds (usually 
H2S) at concentrations of 10 parts per million by weight or 
more.

[[Page 377]]

    Sulfur pit means the storage vessel in which sulfur that is 
condensed after each Claus catalytic reactor is initially accumulated 
and stored. A sulfur pit does not include secondary sulfur storage 
vessels downstream of the initial Claus reactor sulfur pits.
    Sulfur recovery plant means all process units which recover sulfur 
from H2S and/or SO2 from a common source of sour 
gas produced at a petroleum refinery. The sulfur recovery plant also 
includes sulfur pits used to store the recovered sulfur product, but it 
does not include secondary sulfur storage vessels or loading facilities 
downstream of the sulfur pits. For example, a Claus sulfur recovery 
plant includes: Reactor furnace and waste heat boiler, catalytic 
reactors, sulfur pits and, if present, oxidation or reduction control 
systems or incinerator, thermal oxidizer or similar combustion device. 
Multiple sulfur recovery units are a single affected facility only when 
the units share the same source of sour gas. Sulfur recovery plants that 
receive source gas from completely segregated sour gas treatment systems 
are separate affected facilities.
    Sweep gas means the gas introduced in a flare gas header system to 
maintain a constant flow of gas to prevent oxygen buildup in the flare 
header. For flares with no water seals, sweep gas also performs the 
function of preventing oxygen infiltration (backflow) into the flare 
tip.

gas, identify the type of gas used. Designate which lines are exempt 
from sulfur, H2S or flow monitoring and why (e.g., natural 
gas, inherently low sulfur, pilot gas). Designate which lines are 
monitored and identify on the process flow diagram the location and type 
of each monitor.
    (v) For each flow rate, H2S, sulfur content, pressure or 
water seal monitor identified in paragraph (a)(3)(iv) of this section, 
provide a detailed description of the manufacturer's specifications, 
including, but not limited to, make, model, type, range, precision, 
accuracy, calibration, maintenance and quality assurance procedures.

monitoring parameters and procedures used to minimize the duration of 
releases during compressor staging and a justification for why the 
maximum time period cannot be further reduced.
    (4) An evaluation of the baseline flow to the flare. The baseline 
flow to the flare must be determined after implementing the minimization 
assessment in paragraph (a)(2) of this section. Baseline flows do not 
include pilot gas flow or purge gas flow (i.e., gas introduced after the 
flare's water seal) provided these gas flows remain reasonably constant 
(i.e., separate flow monitors for these streams are not required). 
Separate baseline flow rates may be established for different operating 
conditions provided that the management plan includes:
    (i) A primary baseline flow rate that will be used as the default 
baseline for all conditions except those specifically delineated in the 
plan;
    (ii) A description of each special condition for which an alternate 
baseline is established, including the rationale for each alternate 
baseline, the daily flow for each alternate baseline and the expected 
duration of the special conditions for each alternate baseline; and
    (iii) Procedures to minimize discharges to the affected flare during 
each special condition described in paragraph (a)(4)(ii) of this 
section, unless procedures are already developed for these cases under 
paragraph (a)(5) through (7) of this section, as applicable.
    (5) Procedures to minimize or eliminate discharges to the flare 
during the planned startup and shutdown of the refinery process units 
and ancillary equipment that are connected to the affected flare, 
together with a schedule for the prompt implementation of any procedures 
that cannot reasonably be implemented as of the date of the submission 
of the flare management plan.
    (6) Procedures to reduce flaring in cases of fuel gas imbalance 
(i.e., excess fuel gas for the refinery's energy needs), together with a 
schedule for the prompt implementation of any procedures that cannot 
reasonably be implemented as of the date of the submission of the flare 
management plan.
    (7) For flares equipped with flare gas recovery systems, procedures 
to minimize the frequency and duration of outages of the flare gas 
recovery system and procedures to minimize the volume of gas flared 
during such outages, together with a schedule for the prompt 
implementation of any procedures that cannot reasonably be implemented 
as of the date of the submission of the flare management plan.
    (b) Except as provided in paragraph (g) of this section, each owner 
or operator required to develop and implement a written flare management 
plan as described in paragraph (a) of this section must submit the plan 
to the

[[Page 385]]

Administrator as described in paragraphs (b)(1) through (3) of this 
section.
    (1) The owner or operator of a newly constructed or reconstructed 
flare must develop and implement the flare management plan by no later 
than the date that the flare becomes an affected facility subject to 
this subpart, except for the selected minimization alternatives in 
paragraph (a)(2) and/or the procedures in paragraphs (a)(5) though 
(a)(7) of this section that cannot reasonably be implemented by that 
date, which the owner or operator must implement in accordance with the 
schedule in the flare management plan. The owner or operator of a 
modified flare must develop and implement the flare management plan by 
no later than November 11, 2015 or upon startup of the modified flare, 
whichever is later.
    (2) The owner or operator must comply with the plan as submitted by 
the date specified in paragraph (b)(1) of this section. The plan should 
be updated periodically to account for changes in the operation of the 
flare, such as new connections to the flare or the installation of a 
flare gas recovery system, but the plan need be re-submitted to the 
Administrator only if the owner or operator adds an alternative baseline 
flow rate, revises an existing baseline as described in paragraph (a)(4) 
of this section, installs a flare gas recovery system or is required to 
change flare designations and monitoring methods as described in Sec. 
60.107a(g). The owner or operator must comply with the updated plan as 
submitted.
    (3) All versions of the plan submitted to the Administrator shall 
also be submitted to the following address: U.S. Environmental 
Protection Agency, Office of Air Quality Planning and Standards, Sector 
Policies and Programs Division, U.S. EPA Mailroom (E143-01), Attention: 
Refinery Sector Lead, 109 T.W. Alexander Drive, Research Triangle Park, 
NC 27711. Electronic copies in lieu of hard copies may also be submitted 
to [email protected].
    (c) Except as provided in paragraphs (f) and (g) of this section, 
each owner or operator that operates a fuel gas combustion device, flare

cause analysis and a corrective action analysis for each of the 
conditions specified in paragraphs (c)(1) through (3) of this section.
    (1) For a flare:
    (i) Any time the SO2 emissions exceed 227 kilograms (kg) 
(500 lb) in any 24-hour period; or
    (ii) Any discharge to the flare in excess of 14,160 standard cubic 
meters (m\3\) (500,000 standard cubic feet (scf)) above the baseline, 
determined in paragraph (a)(4) of this section, in any 24-hour period; 
or
    (iii) If the monitoring alternative in Sec. 60.107a(g) is elected, 
any period when the flare gas line pressure exceeds the water seal 
liquid depth, except for periods attributable to compressor staging that 
do not exceed the staging time specified in paragraph (a)(3)(vii)(C) of 
this section.
    (2) For a fuel gas combustion device, each exceedance of an 
applicable short-term emissions limit in Sec. 60.102a(g)(1) if the 
SO2 discharge to the atmosphere is 227 kg (500 lb) greater 
than the amount that would have been emitted if the emissions limits had 
been met during one or more consecutive periods of excess emissions or 
any 24-hour period, whichever is shorter.
    (3) For a sulfur recovery plant, each time the SO2 
emissions are more than 227 kg (500 lb) greater than the amount that 
would have been emitted if the SO2 or reduced sulfur 
concentration was equal to the applicable emissions limit in Sec. 
60.102a(f)(1) or (2) during one or more consecutive periods of excess 
emissions or any 24-hour period, whichever is shorter.
    (d) Except as provided in paragraphs (f) and (g) of this section, a 
root cause analysis and corrective action analysis must be completed as 
soon as possible, but no later than 45 days after a discharge meeting 
one of the conditions specified in paragraphs (c)(1) through (3) of this 
section. Special circumstances affecting the number of root cause 
analyses and/or corrective action analyses are provided in paragraphs 
(d)(1) through (5) of this section.

analysis may be conducted.
    (2) If a single discharge from a flare triggers a root cause 
analysis based on more than one of the conditions specified in 
paragraphs (c)(1)(i) through (iii) of this section, a single root cause 
analysis and corrective action analysis may be conducted.
    (3) If the discharge from a flare is the result of a planned startup 
or shutdown of a refinery process unit or ancillary equipment connected 
to the affected flare and the procedures in paragraph (a)(5) of this 
section were followed, a root cause analysis and corrective action 
analysis is not required; however, the discharge must be recorded as 
described in Sec. 60.108a(c)(6) and reported as described in Sec. 
60.108a(d)(5).
    (4) If both the primary and secondary flare in a cascaded flare 
system meet any of the conditions specified in paragraphs (c)(1)(i) 
through (iii) of this section in the same 24-hour period, a single root 
cause analysis and corrective action analysis may be conducted.
    (5) Except as provided in paragraph (d)(4) of this section, if 
discharges occur that meet any of the conditions specified in paragraphs 
(c)(1) through (3) of this section for more than one affected facility 
in the same 24-hour period, initial root cause analyses shall be 
conducted for each affected facility. If the initial root cause analyses 
indicate that the discharges have the same root cause(s), the initial 
root cause analyses can be recorded as a single root cause analysis and 
a single corrective action analysis may be conducted.
    (e) Except as provided in paragraphs (f) and (g) of this section, 
each owner or operator of a fuel gas combustion device, flare or sulfur 
recovery plant subject to this subpart shall implement the corrective 
action(s) identified in the corrective action analysis conducted

applicable requirements in paragraphs (e)(1) through (3) of this 
section.
    (1) All corrective action(s) must be implemented within 45 days of 
the discharge for which the root cause and corrective action analyses 
were required or as soon thereafter as practicable. If an owner or 
operator concludes that corrective action should not be conducted, the 
owner or operator shall record and explain the basis for that conclusion 
no later than 45 days following the discharge as specified in Sec. 
60.108a(c)(6)(ix).
    (2) For corrective actions that cannot be fully implemented within 
45 days following the discharge for which the root cause and corrective 
action analyses were required, the owner or operator shall develop an 
implementation schedule to complete the corrective action(s) as soon as 
practicable.
    (3) No later than 45 days following the discharge for which a root 
cause and corrective action analyses were required, the owner or 
operator shall record the corrective action(s) completed to date, and, 
for action(s) not already completed, a schedule for implementation, 
including proposed commencement and completion dates as specified in 
Sec. 60.108a(c)(6)(x).
    (f) Modified flares shall comply with the requirements of paragraphs 
(c) through (e) of this section by November 11, 2015 or at startup of 
the modified flare, whichever is later. Modified flares that were not 
affected facilities subject to subpart J of this part prior to becoming 
affected facilities under Sec. 60.100a shall comply with the 
requirements of paragraph (h) of this section and the requirements of 
Sec. 60.107a(a)(2) by November 11, 2015 or at startup of the modified 
flare, whichever is later. Modified flares that were affected facilities 
subject to subpart J of this part prior to becoming affected facilities 
under Sec. 60.100a shall comply with the requirements of paragraph (h) 
of this section and the requirements of Sec. 60.107a(a)(2) by November 
13, 2012 or at startup of the modified flare, whichever is later, except 
that modified flares that have accepted applicability of subpart J under 
a federal consent decree shall comply with the subpart J requirements as 
specified in the consent decree, but shall comply with the requirements 
of paragraph (h) of this section and the requirements of Sec. 
60.107a(a)(2) by no later than November 11, 2015.

an alternative to complying with the requirements of paragraphs (a) 
through (e) of this section. An affected flare subject to this subpart 
located in the South Coast Air Quality Management District (SCAQMD) may 
elect to comply with SCAQMD Rule 1118 as an alternative to complying 
with the requirements of paragraphs (a) through (e) of this section. The 
owner or operator of an affected flare must notify the Administrator 
that the flare is in compliance with BAAQMD Regulation 12, Rule 11 and 
BAAQMD Regulation 12, Rule 12 or SCAQMD Rule 1118. The owner or operator 
of an affected flare shall also submit the existing flare management 
plan to the following address: U.S. Environmental Protection Agency, 
Office of Air Quality Planning and Standards, Sector Policies and 
Programs Division, U.S. EPA Mailroom (E143-01), Attention: Refinery 
Sector Lead, 109 T.W. Alexander Drive, Research Triangle Park, NC 27711.

[email protected].
    (h) Each owner or operator shall not burn in any affected flare any 
fuel gas that contains H2S in excess of 162 ppmv determined 
hourly on a 3-hour rolling average basis. The combustion in a flare of 
process upset gases or fuel gas that is released to the flare as a 
result of relief valve leakage or other emergency malfunctions is exempt 
from this limit.
    (i) Each owner or operator of a delayed coking unit shall depressure 
each coke drum to 5 lb per square inch gauge (psig) or less prior to 
discharging the coke drum steam exhaust to the atmosphere. Until the 
coke drum pressure reaches 5 psig, the coke drum steam exhaust must be 
managed in an enclosed blowdown system and the uncondensed vapor must 
either be recovered (e.g., sent to the delayed coking unit 
fractionators) or vented to the fuel gas system, a fuel gas combustion 
device or a flare.
    (j) Alternative means of emission limitation. (1) Each owner or 
operator subject to the provisions of this section may apply to the 
Administrator for a determination of equivalence for any means of 
emission limitation that achieves a reduction in emissions of a 
specified pollutant at least equivalent to the reduction in emissions of 
that pollutant achieved by the controls required in this section.
    (2) Determination of equivalence to the design, equipment, work 
practice or operational requirements of this section will be evaluated 
by the following guidelines:
    (i) Each owner or operator applying for a determination of 
equivalence shall be responsible for collecting and verifying test data 
to demonstrate the equivalence of the alternative means of emission 
limitation.
    (ii) For each affected facility for which a determination of 
equivalence is requested, the emission reduction achieved by the design, 
equipment, work practice or operational requirements shall be 
demonstrated.
    (iii) For each affected facility for which a determination of 
equivalence is requested, the emission reduction achieved by the 
alternative means of emission limitation shall be demonstrated.
    (iv) Each owner or operator applying for a determination of 
equivalence to a work practice standard shall commit in writing to work 
practice(s) that provide for emission reductions equal to or greater 
than the emission reductions achieved by the required work practice.
    (v) The Administrator will compare the demonstrated emission 
reduction for the alternative means of emission limitation to the 
demonstrated emission reduction for the design, equipment, work practice 
or operational requirements and, if applicable, will consider the 
commitment in paragraph (j)(2)(iv) of this section.
    (vi) The Administrator may condition the approval of the alternative 
means of emission limitation on requirements that may be necessary to 
ensure operation and maintenance to achieve the same emissions reduction 
as the design, equipment, work practice or operational requirements.
    (3) An owner or operator may offer a unique approach to demonstrate 
the equivalence of any equivalent means of emission limitation.
    (4) Approval of the application for equivalence to the design, 
equipment,

[[Page 388]]

work practice or operational requirements of this section will be 
evaluated by the following guidelines:
    (i) After a request for determination of equivalence is received, 
the Administrator will publish a notice in the Federal Register and 
provide the opportunity for public hearing if the Administrator judges 
that the request may be approved.
    (ii) After notice and opportunity for public hearing, the 
Administrator will determine the equivalence of a means of emission 
limitation and will publish the determination in the Federal Register.
    (iii) Any equivalent means of emission limitations approved under 
this section shall constitute a required work practice, equipment, 
design or operational standard within the meaning of section 111(h)(1) 
of the CAA.
    (5) Manufacturers of equipment used to control emissions may apply 
to the Administrator for determination of equivalence for any 
alternative means of emission limitation that achieves a reduction in 
emissions achieved by the equipment, design and operational requirements 
of this section. The Administrator will make an equivalence 
determination according to the provisions of paragraphs (j)(2) through 
(4) of this section.

Use Method 5 or 5B of appendix A-3 to part 60 for determining PM 
emissions and associated moisture content from a FCCU or FCU with a wet 
scrubber subject to the emissions limit in Sec. 63.102a(b)(1).
    (i) The PM performance test consists of 3 valid test runs; the 
duration of each test run must be no less than 60 minutes.

alternative to EPA Method 3B of appendix A-2 to part 60.
    (4) Method 6, 6A, or 6C of appendix A-4 to part 60 to determine the 
SO2 concentration. The method ANSI/ASME PTC 19.10-1981, 
``Flue and Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 
60.17) is an acceptable alternative to EPA Method 6 or 6A of appendix A-
4 to part 60.
    (5) Method 15 or 15A of appendix A-5 to part 60 or Method 16 of 
appendix A-6 to part 60 to determine the reduced sulfur compounds and 
H2S concentrations. The method ANSI/ASME PTC 19.10-1981, 
``Flue and Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 
60.17) is an acceptable alternative to EPA Method 15A of appendix A-5 to 
part 60.
    (i) Each run consists of 16 samples taken over a minimum of 3 hours.
    (ii) The owner or operator shall calculate the average 
H2S concentration after correcting for moisture and 
O2 as the arithmetic average of the H2S 
concentration for each sample during the run (ppmv, dry basis, corrected 
to 0 percent excess air).
    (iii) The owner or operator shall calculate the SO2 
equivalent for each run after correcting for moisture and O2 
as the arithmetic average of the SO2 equivalent of reduced

concentration of the air/oxygen mixture supplied to the Claus burner, in 
percent by volume (dry basis), for the performance test using all hourly 
average O2 concentrations determined during the test runs 
using the procedures in Sec. 60.106a(a)(5) or (6).
    (i) The owner or operator shall determine compliance with the

The method ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses,'' 
(incorporated by reference--see Sec. 60.17) is an acceptable 
alternative to EPA Method 3B of appendix A-2 to part 60;
    (4) Method 6, 6A, or 6C of appendix A-4 to part 60 to determine the 
SO2 concentration. The method ANSI/ASME PTC 19.10-1981, 
``Flue and Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 
60.17) is an acceptable alternative to EPA Method 6 or 6A of appendix A-
4 to part 60.
    (i) The performance test consists of 3 valid test runs; the duration 
of each test run must be no less than 1 hour.
    (ii) If a single fuel gas combustion device having a common source 
of fuel gas is monitored as allowed under Sec. 60.107a(a)(1)(v), only 
one performance test is required. That is, performance tests are not 
required when a new affected fuel gas combustion device is added to a 
common source of fuel gas that previously demonstrated compliance.
    (5) Method 7, 7A, 7C, 7D, or 7E of appendix A-4 to part 60 for 
moisture content and for the concentration of NOX calculated 
as NO2; the duration of each test run must be no less than 4 
hours. The method ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas 
Analyses,'' (incorporated by reference--see Sec. 60.17) is an 
acceptable alternative to EPA Method 7 or 7C of appendix A-4 to part 60.
    (6) For process heaters with a rated heat capacity between 40 and 
100 MMBtu/hr that elect to demonstrate continuous compliance with a 
maximum excess oxygen limit as provided in Sec. 60.107a(c)(6) or 
(d)(8), the owner or operator shall establish the O2 
operating limit or O2 operating curve based on the 
performance test results according to the requirements in paragraph 
(i)(6)(i) or (ii) of this section, respectively.
    (i) If a single O2 operating limit will be used:
    (A) Conduct the performance test following the methods provided in 
paragraphs (i)(1), (2), (3) and (5) of this section when the process 
heater is firing at no less than 70 percent of the rated heat capacity. 
For co-fired process heaters, conduct at least one of the test runs 
while the process heater is being supplied by both fuel gas and fuel oil 
and conduct at least one of the test runs while the process heater is 
being supplied solely by fuel gas.
    (B) Each test will consist of three test runs. Calculate the 
NOX concentration for the performance test as the average of 
the NOX concentrations from each of the three test runs. If 
the NOX concentration for the performance test is less than 
or equal to the numerical value of the applicable NOX 
emissions limit (regardless of averaging time), then the test is 
considered to be a valid test.
    (C) Determine the average O2 concentration for each test 
run of a valid test.
    (D) Calculate the O2 operating limit as the average 
O2 concentration of the three test runs from a valid test.
    (ii) If an O2 operating curve will be used:
    (A) Conduct a performance test following the methods provided in 
paragraphs (i)(1), (2), (3) and (5) of this section at a representative 
condition for each operating range for which different O2 
operating limits will be established. Different operating conditions may 
be defined as different firing rates (e.g., above 50 percent of rated 
heat capacity and at or below 50 percent of rated heat capacity) and/or, 
for co-fired process heaters, different fuel mixtures (e.g., primarily 
gas fired, primarily oil fired, and equally co-fired, i.e., 
approximately 50 percent of the input heating value is from fuel gas and 
approximately 50 percent of the input heating value is from fuel oil). 
Performance tests for different operating ranges may be conducted at 
different times.
    (B) Each test will consist of three test runs. Calculate the 
NOX concentration for the performance test as the average of 
the NOX concentrations from each of the three test runs. If 
the NOX concentration for the performance test is less than 
or equal to the numerical value of the applicable NOX 
emissions limit (regardless of averaging time),

[[Page 393]]

then the test is considered to be a valid test.
    (C) If an operating curve is developed for different firing rates, 
conduct at least one test when the process heater is firing at no less 
than 70 percent of the rated heat capacity and at least one test under 
turndown conditions (i.e., when the process heater is firing at 50 
percent or less of the rated heat capacity). If O2 operating 
limits are developed for co-fired process heaters based only on overall 
firing rates (and not by fuel mixtures), conduct at least one of the 
test runs for each test while the process heater is being supplied by 
both fuel gas and fuel oil and conduct at least one of the test runs 
while the process heater is being supplied solely by fuel gas.
    (D) Determine the average O2 concentration for each test 
run of a valid test.
    (E) Calculate the O2 operating limit for each operating 
range as the average O2 concentration of the three test runs 
from a valid test conducted at the representative conditions for that 
given operating range.
    (F) Identify the firing rates for which the different operating 
limits apply. If only two operating limits are established based on 
firing rates, the O2 operating limits established when the 
process heater is firing at no less than 70 percent of the rated heat 
capacity must apply when the process heater is firing above 50 percent 
of the rated heat capacity and the O2 operating limits 
established for turndown conditions must apply when the process heater 
is firing at 50 percent or less of the rated heat capacity.
    (G) Operating limits associated with each interval will be valid for 
2 years or until another operating limit is established for that 
interval based on a more recent performance test specific for that 
interval, whichever occurs first. Owners and operators must use the 
operating limits determined for a given interval based on the most 
recent performance test conducted for that interval.
    (7) The owner or operator of a process heater complying with a 
NOX limit in terms of lb/MMBtu as provided in Sec. 
60.102a(g)(2)(i)(B), (g)(2)(ii)(B), (g)(2)(iii)(B) or (g)(2)(iv)(B) or a 
process heater with a rated heat capacity between 40 and 100 MMBtu/hr 
that elects to demonstrate continuous compliance with a maximum excess 
O2 limit, as provided in Sec. 60.107a(c)(6) or (d)(8), shall 
determine heat input to the process heater in MMBtu/hr during each 
performance test run by measuring fuel gas flow rate, fuel oil flow rate 
(as applicable) and heating value content according to the methods 
provided in Sec. 60.107a(d)(5), (d)(6), and (d)(4) or (d)(7), 
respectively.
    (8) The owner or operator shall use Equation 8 of this section to 
adjust pollutant concentrations to 0-percent O2 or 0- percent 
excess air.
    (j) The owner or operator shall determine compliance with the 
applicable H2S emissions limit in Sec. 60.102a(g)(1) for a 
fuel gas combustion device or the concentration requirement in Sec. 
60.103a(h) for a flare according to the following test methods and 
procedures:
    (1)--(3) [Reserved]
    (4) EPA Method 11, 15 or 15A of appendix A-5 to part 60 or EPA 
Method 16 of appendix A-6 to part 60 for determining the H2S 
concentration for affected facilities using an H2S monitor as 
specified in Sec. 60.107a(a)(2). The method ANSI/ASME PTC 19.10-1981 
(incorporated by reference--see Sec. 60.17) is an acceptable 
alternative to EPA Method 15A of appendix A-5 to part 60. The owner or 
operator may demonstrate compliance based on the mixture used in the 
fuel gas combustion device or flare or for each individual fuel gas 
stream used in the fuel gas combustion device or flare.
    (i) For Method 11 of appendix A-5 to part 60, the sampling time and 
sample volume must be at least 10 minutes and 0.010 dscm (0.35 dscf). 
Two samples of equal sampling times must be taken at about 1-hour 
intervals. The arithmetic average of these two samples constitutes a 
run. For most fuel gases, sampling times exceeding 20 minutes may result 
in depletion of the collection solution, although fuel gases containing 
low concentrations of H2S may necessitate sampling for longer 
periods of time.
    (ii) For Method 15 of appendix A-5 to part 60, at least three 
injects over a 1-hour period constitutes a run.

[[Page 394]]

    (iii) For Method 15A of appendix A-5 to part 60, a 1-hour sample 
constitutes a run. The method ANSI/ASME PTC 19.10-1981, ``Flue and 
Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 60.17) is 
an acceptable alternative to EPA Method 15A of appendix A-5 to part 60.
    (iv) If monitoring is conducted at a single point in a common source 
of fuel gas as allowed under Sec. 60.107a(a)(2)(iv), only one 
performance test is required. That is, performance tests are not 
required when a new affected fuel gas combustion device or flare is 
added to a common source of fuel gas that previously demonstrated 
compliance.

appendix B to this part. The owner or operator shall use Method 3, 3A or 
3B of appendix A-2 to this part for conducting the relative accuracy 
evaluations. The method ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas 
Analyses,'' (incorporated by reference--see Sec. 60.17) is an 
acceptable alternative to EPA Method 3B of appendix A-2 to part 60.
    (iii) If a CO monitor is required, the owner or operator shall

Specification 4 or 4A of appendix B to this part. If this CO monitor 
also serves to demonstrate compliance with the CO emissions limit in 
Sec. 60.102a(b)(4), the span value for this instrument is 1,000 ppm; 
otherwise, the span value for this instrument should be set at 
approximately 2 times the typical CO concentration expected in the FCCU 
of FCU flue gas prior to any emission control or energy recovery system 
that burns auxiliary fuels.

with the PM per coke burn-off emissions limit in Sec. 60.102a(b)(1) for 
an FCCU or FCU according to paragraph (c)(1) of this section; prepare 
and operate by a site-specific monitoring plan according to paragraph 
(c)(2) of this section; take action according to paragraph (c)(3) of 
this section; and record information according to paragraph (c)(4) of 
this section.

manufacturer to be capable of detecting PM emissions at concentrations 
of 0.00044 grains per actual cubic foot or less.
    (ii) The bag leak detection system sensor must provide output of 
relative PM loadings. The owner or operator shall continuously record 
the output from the bag leak detection system using electronic or other 
means (e.g.,

[[Page 396]]

using a strip chart recorder or a data logger).
    (iii) The bag leak detection system must be equipped with an alarm 
system that will sound when the system detects an increase in relative 
particulate loading over the alarm set point established according to 
paragraph (c)(1)(iv) of this section, and the alarm must be located such

    (iv) In the initial adjustment of the bag leak detection system, the 
owner or operator must establish, at a minimum, the baseline output by 
adjusting the sensitivity (range) and the averaging period of the 
device, the alarm set points, and the alarm delay time.
    (v) Following initial adjustment, the owner or operator shall not 
adjust the averaging period, alarm set point, or alarm delay time 
without approval from the Administrator or delegated authority except as 
provided in paragraph (c)(1)(vi) of this section.
    (vi) Once per quarter, the owner or operator may adjust the 
sensitivity of the bag leak detection system to account for seasonal 
effects, including temperature and humidity, according to the procedures 
identified in the site-specific monitoring plan required by paragraph 
(c)(2) of this section.
    (vii) The owner or operator shall install the bag leak detection 
sensor downstream of the baghouse and upstream of any wet scrubber.
    (viii) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (2) The owner or operator shall develop and submit to the 
Administrator for approval a site-specific monitoring plan for each 
baghouse and bag leak detection system. The owner or operator shall 
operate and maintain each baghouse and bag leak detection system 
according to the site-specific monitoring plan at all times. Each

approving the site-specific monitoring plan, the Administrator or 
delegated authority may allow owners and operators more than 3 hours to 
alleviate a specific condition that causes an alarm if the owner or 
operator identifies in the monitoring plan this specific condition as 
one that could lead to an alarm, adequately explains why it is not 
feasible to alleviate this condition within 3 hours of the time the 
alarm occurs, and demonstrates that the requested time will ensure 
alleviation of this condition as expeditiously as practicable; and
    (vii) How the baghouse system will be operated and maintained, 
including monitoring of pressure drop across baghouse cells and 
frequency of visual inspections of the baghouse interior and baghouse

time that procedures to determine the cause of the alarm were initiated, 
the cause of the alarm, an explanation of the actions taken, the date 
and time the cause of the alarm was alleviated, and whether the alarm 
was alleviated within 3 hours of the alarm.
    (d) Continuous emissions monitoring systems (CEMS). An owner or 
operator subject to the PM concentration emission limit (in gr/dscf) in 
Sec. 60.102a(b)(1) for an FCCU or FCU shall install, operate, 
calibrate, and maintain an instrument for continuously monitoring and

accuracy evaluations.
    (3) The owner or operator shall install, operate, and maintain each 
O2 monitor according to Performance Specification 3 of 
appendix B to part 60. The span value of this O2 monitor must

concentration to determine the flow weighted average hourly emission 
limit for each hour. The allowable emission limit shall be calculated as 
the arithmetic average of 12 contiguous 1-hour averages (i.e., the 
rolling 12-hour average).

60.13(c) and Performance Specification 2 of appendix B to this part. The 
owner or operator shall use Methods 6, 6A, or 6C of appendix A-4 to this 
part for conducting the relative accuracy evaluations. The method ANSI/
ASME PTC 19.10-1981 (incorporated by reference--see Sec. 60.17) is an 
acceptable alternative to EPA Method 6 or 6A of appendix A-4 to this 
part. Samples taken by Method 6 of appendix A-4 to this part shall be 
taken at a flow rate of approximately 2 liters/min for at least 30 
minutes. The relative accuracy limit shall be 20 percent or 4 ppmv, 
whichever is greater, and the calibration drift limit shall be 5 percent

the O2 monitor according to the requirements of Sec. 
60.13(c) and Performance Specification 3 of appendix B to part 60. The 
owner or operator shall use Methods 3, 3A, or 3B of appendix A-2 to part 
60 for conducting the relative accuracy evaluations. The method ANSI/
ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses,'' (incorporated by 
reference--see Sec. 60.17) is an acceptable alternative to EPA Method 
3B of appendix A-2 to part 60.
    (v) The owner or operator shall comply with the applicable quality 
assurance procedures in appendix F to part 60, including quarterly 
accuracy determinations for SO2 monitors, annual accuracy 
determinations for O2 monitors, and daily calibration drift 
tests.
    (vi) Fuel gas combustion devices having a common source of fuel gas 
may be monitored at only one location (i.e., after one of the combustion 
devices), if monitoring at this location accurately represents the 
SO2 emissions into the atmosphere from each of the combustion 
devices.
    (2) The owner or operator of a fuel gas combustion device that 
elects to comply with the H2S concentration limits in Sec. 
60.102a(g)(1)(ii) or a flare that is subject to the H2S 
concentration requirement in Sec. 60.103a(h) shall install, operate, 
calibrate and maintain an instrument for continuously monitoring and 
recording the concentration by volume (dry basis) of H2S in 
the fuel gases before being burned in any fuel gas combustion device or

owner or operator shall use Method 11, 15, or 15A of appendix A-5 to 
part 60 or Method 16 of appendix A-6 to part 60 for conducting the 
relative accuracy evaluations. The method ANSI/ASME PTC 19.10-1981, 
``Flue and Exhaust Gas Analyses,'' (incorporated by reference--see Sec. 
60.17) is an acceptable alternative to EPA Method 15A of appendix A-5 to 
part 60.
    (iii) The owner or operator shall comply with the applicable quality 
assurance procedures in appendix F to part 60 for each H2S 
monitor.
    (iv) Fuel gas combustion devices or flares having a common source of

through (e) may use the instrument required in paragraph (e)(1) of this 
section to demonstrate compliance with the H2S concentration 
requirement in Sec. 60.103a(h) if the owner or operator complies with 
the requirements of paragraph (e)(1)(i) through (iv) and if the 
instrument has a span (or dual span, if necessary) capable of accurately 
measuring concentrations between 20 and 300 ppmv. If the instrument 
required in paragraph (e)(1) of this section is used to demonstrate 
compliance with the H2S concentration requirement, the 
concentration directly measured by the instrument must meet the numeric 
concentration in Sec. 60.103a(h).
    (vi) The owner or operator of modified flare that meets all three 
criteria in paragraphs (a)(2)(vi)(A) through (C) of this section shall 
comply with the requirements of paragraphs (a)(2)(i) through (v) of this

to Sec. 60.13(i) until the flare is in compliance with requirements of 
paragraphs (a)(2)(i) through (v) of this section.
    (A) The flare was an affected facility subject to subpart J of this 
part prior to becoming an affected facility under Sec. 60.100a.

[[Page 407]]

    (B) The owner or operator had an approved alternative monitoring 
plan or plans pursuant to Sec. 60.13(i) for all fuel gases combusted in 
the flare.
    (C) The flare did not have in place on or before September 12, 2012 
an instrument for continuously monitoring and recording the 
concentration by volume (dry basis) of H2S in the fuel gases 
that is capable of complying with the requirements of paragraphs 
(a)(2)(i) through (v) of this section.
    (3) The owner or operator of a fuel gas combustion device or flare 
is not required to comply with paragraph (a)(1) or (2) of this section 
for fuel gas streams that are exempt under Sec. Sec. 60.102a(g)(1)(iii) 
or 60.103a(h) or, for fuel gas streams combusted in a process heater, 
other fuel gas combustion device or flare that are inherently low in 
sulfur content. Fuel gas streams meeting one of the requirements in 
paragraphs (a)(3)(i) through (iv) of this section will be considered 
inherently low in sulfur content.
    (i) Pilot gas for heaters and flares.
    (ii) Fuel gas streams that meet a commercial-grade product 
specification for sulfur content of 30 ppmv or less. In the case of a 
liquefied petroleum gas (LPG) product specification in the pressurized 
liquid state, the gas phase sulfur content should be evaluated assuming 
complete vaporization of the LPG and sulfur containing-compounds at the 
product specification concentration.
    (iii) Fuel gas streams produced in process units that are intolerant 
to sulfur contamination, such as fuel gas streams produced in the 
hydrogen plant, catalytic reforming unit, isomerization unit, and HF 
alkylation process units.
    (iv) Other fuel gas streams that an owner or operator demonstrates 
are low-sulfur according to the procedures in paragraph (b) of this 
section.
    (4) If the composition of an exempt fuel gas stream changes, the 
owner or operator must follow the procedures in paragraph (b)(3) of this 
section.
    (b) Exemption from H2S monitoring requirements for low-
sulfur fuel gas streams. The owner or operator of a fuel gas combustion 
device or flare may apply for an exemption from the H2S 
monitoring requirements in paragraph (a)(2) of this section for a fuel 
gas stream that is inherently low in sulfur content. A fuel gas stream 
that is demonstrated to be low-sulfur is exempt from the monitoring 
requirements of paragraphs (a)(1) and (2) of this section until there 
are changes in operating conditions or stream composition.
    (1) The owner or operator shall submit to the Administrator a 
written application for an exemption from monitoring. The application 
must contain the following information:
    (i) A description of the fuel gas stream/system to be considered, 
including submission of a portion of the appropriate piping diagrams 
indicating the boundaries of the fuel gas stream/system and the affected 
fuel gas combustion device(s) or flare(s) to be considered;
    (ii) A statement that there are no crossover or entry points for 
sour gas (high H2S content) to be introduced into the fuel 
gas stream/system (this should be shown in the piping diagrams);
    (iii) An explanation of the conditions that ensure low amounts of 
sulfur in the fuel gas stream (i.e., control equipment or product 
specifications) at all times;
    (iv) The supporting test results from sampling the requested fuel 
gas stream/system demonstrating that the sulfur content is less than 5 
ppmv H2S. Sampling data must include, at minimum, 2 weeks of 
daily monitoring (14 grab samples) for frequently operated fuel gas 
streams/systems; for infrequently operated fuel gas streams/systems, 
seven grab samples must be collected unless other additional information 
would support reduced sampling. The owner or operator shall use detector 
tubes (``length-of-stain tube'' type measurement) following the ``Gas 
Processors Association Standard 2377-86 (incorporated by reference--see 
Sec. 60.17), using tubes with a maximum span between 10 and 40 ppmv 
inclusive when 1<=N<=10, where N = number of pump strokes, to test the 
applicant fuel gas stream for H2S; and
    (v) A description of how the 2 weeks (or seven samples for 
infrequently operated fuel gas streams/systems) of monitoring results 
compares to the typical range of H2S concentration

[[Page 408]]

(fuel quality) expected for the fuel gas stream/system going to the 
affected fuel gas combustion device or flare (e.g., the 2 weeks of daily 
detector tube results for a frequently operated loading rack included 
the entire range of products loaded out and, therefore, should be 
representative of typical operating conditions affecting H2S 
content in the fuel gas stream going to the loading rack flare).
    (2) The effective date of the exemption is the date of submission of 
the information required in paragraph (b)(1) of this section.
    (3) No further action is required unless refinery operating 
conditions change in such a way that affects the exempt fuel gas stream/
system (e.g., the stream composition changes). If such a change occurs, 
the owner or operator shall follow the procedures in paragraph 
(b)(3)(i), (b)(3)(ii), or (b)(3)(iii) of this section.
    (i) If the operation change results in a sulfur content that is 
still within the range of concentrations included in the original 
application, the owner or operator shall conduct an H2S test 
on a grab sample and record the results as proof that the concentration 
is still within the range.
    (ii) If the operation change results in a sulfur content that is 
outside the range of concentrations included in the original 
application, the owner or operator may submit new information following 
the procedures of paragraph (b)(1) of this section within 60 days (or 
within 30 days after the seventh grab sample is tested for infrequently 
operated process units).
    (iii) If the operation change results in a sulfur content that is 
outside the range of concentrations included in the original application 
and the owner or operator chooses not to submit new information to 
support an exemption, the owner or operator must begin H2S 
monitoring using daily stain sampling to demonstrate compliance using 
length-of-stain tubes with a maximum span between 200 and 400 ppmv 
inclusive when 1<=N<=5, where N = number of pump strokes. The owner or 
operator must begin monitoring according to the requirements in 
paragraphs (a)(1) or (a)(2) of this section as soon as practicable, but 
in no case later than 180 days after the operation change. During daily 
stain tube sampling, a daily sample exceeding 162 ppmv is an exceedance 
of the 3-hour H2S concentration limit. The owner or operator 
of a fuel gas combustion device must also determine a rolling 365-day 
average using the stain sampling results; an average H2S 
concentration of 5 ppmv must be used for days within the rolling 365-day 
period prior to the operation change.
    (c) Process heaters complying with the NOX concentration-
based limit. The owner or operator of a process heater subject to the 
NOX emissions limit in Sec. 60.102a(g)(2) and electing to 
comply with the applicable emissions limit in Sec. 60.102a(g)(2)(i)(A), 
(g)(2)(ii)(A), (g)(2)(iii)(A) or (g)(2)(iv)(A) shall install, operate, 
calibrate and maintain an instrument for continuously monitoring and 
recording the concentration (dry basis, 0-percent excess air) of 
NOX emissions into the atmosphere according to the 
requirements in paragraphs (c)(1) through (5) of this section, except as 
provided in paragraph (c)(6) of this section. The monitor must include 
an O2 monitor for correcting the data for excess air.
    (1) Except as provided in paragraph (c)(6) of this section, the 
owner or operator shall install, operate and maintain each 
NOX monitor according to Performance Specification 2 of 
appendix B to part 60. The span value of this NOX monitor 
must be between 2 and 3 times the applicable emissions limit, inclusive.
    (2) The owner or operator shall conduct performance evaluations of 
each NOX monitor according to the requirements in Sec. 
60.13(c) and Performance Specification 2 of appendix B to part 60. The 
owner or operator shall use Methods 7, 7A, 7C, 7D, or 7E of appendix A-4 
to part 60 for conducting the relative accuracy evaluations. The method 
ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses,'' 
(incorporated by reference--see Sec. 60.17) is an acceptable 
alternative to EPA Method 7 or 7C of appendix A-4 to part 60.
    (3) The owner or operator shall install, operate, and maintain each 
O2 monitor according to Performance Specification 3 of 
appendix B to part 60. The span value of this O2 monitor must

[[Page 409]]

be selected between 10 and 25 percent, inclusive.
    (4) The owner or operator shall conduct performance evaluations of 
each O2 monitor according to the requirements in Sec. 
60.13(c) and Performance Specification 3 of appendix B to part 60. 
Method 3, 3A, or 3B of appendix A-2 to part 60 shall be used for 
conducting the relative accuracy evaluations. The method ANSI/ASME PTC 
19.10-1981, ``Flue and Exhaust Gas Analyses,'' (incorporated by 
reference--see Sec. 60.17) is an acceptable alternative to EPA Method 
3B of appendix A-2 to part 60.
    (5) The owner or operator shall comply with the quality assurance 
requirements in Procedure 1 of appendix F to part 60 for each 
NOX and O2 monitor, including quarterly accuracy 
determinations for NOX monitors, annual accuracy 
determinations for O2 monitors, and daily calibration drift 
tests.
    (6) The owner or operator of a process heater that has a rated 
heating capacity of less than 100 MMBtu and is equipped with combustion 
modification-based technology to reduce NOX emissions (i.e., 
low-NOX burners, ultra-low-NOX burners) may elect 
to comply with the monitoring requirements in paragraphs (c)(1) through 
(5) of this section or, alternatively, the owner or operator of such a 
process heater shall conduct biennial performance tests according to the 
requirements in Sec. 60.104a(i), establish a maximum excess 
O2 operating limit or operating curve according to the 
requirements in Sec. 60.104a(i)(6) and comply with the O2 
monitoring requirements in paragraphs (c)(3) through (5) of this section 
to demonstrate compliance. If an O2 operating curve is used 
(i.e., if different O2 operating limits are established for 
different operating ranges), the owner or operator of the process heater 
must also monitor fuel gas flow rate, fuel oil flow rate (as applicable) 
and heating value content according to the methods provided in 
paragraphs (d)(5), (d)(6), and (d)(4) or (d)(7) of this section, 
respectively.
    (d) Process heaters complying with the NOX heating value-
based or mass-based limit. The owner or operator of a process heater 
subject to the NOX emissions limit in Sec. 60.102a(g)(2) and 
electing to comply with the applicable emissions limit in Sec. 
60.102a(g)(2)(i)(B) or (g)(2)(ii)(B) shall install, operate, calibrate 
and maintain an instrument for continuously monitoring and recording the 
concentration (dry basis, 0-percent excess air) of NOX 
emissions into the atmosphere and shall determine the F factor of the 
fuel gas stream no less frequently than once per day according to the 
monitoring requirements in paragraphs (d)(1) through (4) of this 
section. The owner or operator of a co-fired process heater subject to 
the NOX emissions limit in Sec. 60.102a(g)(2) and electing 
to comply with the heating value-based limit in Sec. 
60.102a(g)(2)(iii)(B) or (g)(2)(iv)(B) shall install, operate, calibrate 
and maintain an instrument for continuously monitoring and recording the 
concentration (dry basis, 0-percent excess air) of NOX 
emissions into the atmosphere according to the monitoring requirements 
in paragraph (d)(1) of this section; install, operate, calibrate and

    (1) Except as provided in paragraph (d)(8) of this section, the 
owner or operator shall install, operate and maintain each 
NOX monitor according to the requirements in paragraphs 
(c)(1) through (5) of this section. The monitor must include an

owner or operator shall sample and analyze each fuel stream fed to the 
process heater using the methods and equations in section 12.3.2 of EPA 
Method 19 of appendix A-7 to part 60 to determine the F factor on a dry 
basis. If a single fuel gas system provides fuel gas to several process 
heaters, the F factor may be determined at a single location in the fuel

[[Page 410]]

gas system provided it is representative of the fuel gas fed to the 
affected process heater(s).
    (3) As an alternative to the requirements in paragraph (d)(2) of 
this section, the owner or operator of a gas-fired process heater shall 
install, operate and maintain a gas composition analyzer and determine 
the average F factor of the fuel gas using the factors in Table 1 of 
this subpart and Equation 13 of this section. If a single fuel gas 
system provides fuel gas to several process heaters, the F factor may be 
determined at a single location in the fuel gas system provided it is 
representative of the fuel gas fed to the affected process heater(s).

to use the storage tank sampling method in section 2.2.4.2 of appendix D 
to part 75 instead of daily sampling, except that the most recent value 
for heating content must be used.
    (8) The owner or operator of a process heater that has a rated 
heating capacity of less than 100 MMBtu and is equipped with combustion 
modification based technology to reduce NOX emissions (i.e., 
low-NOX burners or ultra-low NOX burners) may

to the requirements in Sec. 60.104a(i), establish a maximum excess 
O2 operating limit or operating curve according to the 
requirements in Sec. 60.104a(i)(6) and comply with the O2 
monitoring requirements in paragraphs (c)(3) through (5) of this section 
to demonstrate compliance. If an O2 operating curve is used 
(i.e., if different O2 operating limits are established for 
different operating ranges), the owner or operator of the process heater 
must also monitor fuel gas flow rate, fuel oil flow rate (as applicable) 
and heating value content according to the methods provided in 
paragraphs (d)(5), (d)(6), and (d)(4) or (d)(7) of this section, 
respectively.
    (e) Sulfur monitoring for assessing root cause analysis threshold

this section, the owner or operator of an affected flare subject to 
Sec. 60.103a(c) through (e) shall determine the total reduced sulfur 
concentration for each gas line directed to the affected flare in 
accordance with

[[Page 412]]

either paragraph (e)(1), (e)(2) or (e)(3) of this section. Different 
options may be elected for different gas lines. If a monitoring system 
is in place that is capable of complying with the requirements related 
to either paragraph (e)(1), (e)(2) or (e)(3) of this section, the owner 
or operator of a modified flare must comply with the requirements 
related to either paragraph (e)(1), (e)(2) or (e)(3) of this section 
upon startup of the modified flare. If a monitoring system is not in 
place that is capable of complying with the requirements related to 
either paragraph (e)(1), (e)(2) or (e)(3) of this section, the owner or 
operator of a modified flare must comply with the requirements related 
to either paragraph (e)(1), (e)(2) or (e)(3) of this section no later 
than November 11, 2015 or upon startup of the modified flare, whichever 
is later.

operator shall install, operate, calibrate and maintain an instrument or 
instruments for continuously monitoring and recording the concentration 
of total reduced sulfur in gas discharged to the flare.
    (i) The owner or operator shall install, operate and maintain each 
total reduced sulfur monitor according to Performance Specification 5 of 
appendix B to part 60. The span value should be determined based on the 
maximum sulfur content of gas that can be discharged to the flare (e.g., 
roughly 1.1 to 1.3 times the maximum anticipated sulfur concentration), 
but may be no less than 5,000 ppmv. A single dual range monitor may be 
used to comply with the requirements of this paragraph and paragraph 
(a)(2) of this section provided the applicable span specifications are 
met.
    (ii) The owner or operator shall conduct performance evaluations of 
each total reduced sulfur monitor according to the requirements in Sec. 
60.13(c) and Performance Specification 5 of appendix B to this part. The 
owner or operator of each total reduced sulfur monitor shall use EPA 
Method 15A of appendix A-5 to this part for conducting the relative 
accuracy evaluations. The method ANSI/ASME PTC 19.10-1981 (incorporated 
by reference-see Sec. 60.17) is an acceptable alternative to EPA Method 
15A of appendix A-5 to this part. The alternative relative accuracy 
procedures described in section 16.0 of Performance Specification 2 of 
appendix B to this part (cylinder gas audits) may be used for conducting 
the relative accuracy evaluations, except that it is not necessary to 
include as much of the sampling probe or sampling line as practical.
    (iii) The owner or operator shall comply with the applicable quality 
assurance procedures in appendix F to part 60 for each total reduced 
sulfur monitor.
    (2) H2S monitoring requirements. The owner or operator shall 
install, operate, calibrate, and maintain an instrument or instruments

concentrations as specified in paragraphs (e)(2)(iv) through (ix) of 
this section.
    (i) The owner or operator shall install, operate and maintain each 
H2S monitor according to Performance Specification 7 of 
appendix B to part 60. The span value should be determined based on the 
maximum sulfur content of gas that can be discharged to the flare (e.g., 
roughly 1.1 to 1.3 times the maximum anticipated sulfur concentration), 
but may be no less than 5,000 ppmv. A single dual range H2S 
monitor may be used to comply with the requirements of this paragraph 
and paragraph (a)(2) of this section provided the applicable span 
specifications are met.
    (ii) The owner or operator shall conduct performance evaluations of 
each H2S monitor according to the requirements in Sec. 
60.13(c) and Performance Specification 7 of appendix B to this part. The 
owner or operator shall use EPA Method 11, 15 or 15A of appendix A-5 to 
this part for conducting the relative accuracy evaluations. The method 
ANSI/ASME PTC 19.10-1981 (incorporated by reference--see Sec. 60.17) is 
an acceptable alternative to EPA Method 15A of appendix A-5 to this 
part. The alternative relative accuracy procedures described in section 
16.0 of Performance Specification 2 of appendix B

[[Page 413]]

to this part (cylinder gas audits) may be used for conducting the 
relative accuracy evaluations, except that it is not necessary to 
include as much of the sampling probe or sampling line as practical.
    (iii) The owner or operator shall comply with the applicable quality 
assurance procedures in appendix F to part 60 for each H2S 
monitor.
    (iv) In the first 10 operating days after the date the flare must 
begin to comply with Sec. 60.103a(c)(1), the owner or operator shall 
collect representative daily samples of the gas discharged to the flare. 
The samples may be grab samples or integrated samples. The owner or 
operator shall take subsequent representative daily samples at least 
once per week or as required in paragraph (e)(2)(ix) of this section.
    (v) The owner or operator shall analyze each daily sample for total 
sulfur using either EPA Method 15A of appendix A-5 to part 60, EPA 
Method 16A of appendix A-6 to part 60, ASTM Method D4468-85 (Reapproved 
2006) (incorporated by reference--see Sec. 60.17) or ASTM Method D5504-
08 (incorporated by reference--see Sec. 60.17).
    (vi) The owner or operator shall develop a 10-day average total 
sulfur-to-H2S ratio and 95-percent confidence interval as 
follows:
    (A) Calculate the ratio of the total sulfur concentration to the 
H2S concentration for each day during which samples are 
collected.
    (B) Determine the 10-day average total sulfur-to-H2S 
ratio as the arithmetic average of the daily ratios calculated in 
paragraph (e)(2)(vi)(A) of this section.
    (C) Determine the acceptable range for subsequent weekly samples 
based on the 95-percent confidence interval for the distribution of 
daily ratios based on the 10 individual daily ratios using Equation 14 
of this section.

interval for 10 samples (9 degrees of freedom).
    SDev = Standard deviation of the 10 daily average total sulfur-to-
H2S concentration ratios used to develop the 10-day average 
total sulfur-to-H2S concentration ratio, unitless.

    (vii) For each day during the period when data are being collected 
to develop a 10-day average, the owner or operator shall estimate the 
total sulfur concentration using the measured total sulfur concentration 
measured for that day.
    (viii) For all days other than those during which data are being 
collected to develop a 10-day average, the owner or operator shall 
multiply the most recent 10-day average total sulfur-to-H2S 
ratio by the daily average H2S concentrations obtained using 
the monitor as required by paragraph (e)(2)(i) through (iii) of this 
section to estimate total sulfur concentrations.
    (ix) If the total sulfur-to-H2S ratio for a subsequent 
weekly sample is outside the acceptable range for the most recent 
distribution of daily ratios, the owner or operator shall develop a new 
10-day average ratio and acceptable range based on data for the outlying 
weekly sample plus data collected over the following 9 operating days.
    (3) SO2 monitoring requirements. The owner or operator shall 
install, operate, calibrate, and maintain an instrument for continuously 
monitoring and recording the concentration of SO2 from a 
process heater or other fuel gas combustion device that is combusting 
gas representative of the fuel gas in the flare gas line according to

dscf/MMBtu.
    HHVFG = Higher heating value of the fuel gas, MMBtu/scf.

    (4) Exemptions from sulfur monitoring requirements. Flares 
identified in paragraphs (e)(4)(i) through (iv) of this section are 
exempt from the requirements in paragraphs (e)(1) through (3) of this 
section. For each such flare, except as provided in paragraph 
(e)(4)(iv), engineering calculations shall be used to calculate the 
SO2 emissions in the event of a discharge that may trigger a 
root cause analysis under Sec. 60.103a(c)(1).
    (i) Flares that can only receive:
    (A) Fuel gas streams that are inherently low in sulfur content as 
described in paragraph (a)(3)(i) through (iv) of this section; and/or
    (B) Fuel gas streams that are inherently low in sulfur content for 
which the owner or operator has applied for an exemption from the

startup, shutdown or malfunction, provided that for each such flare, the 
owner or operator complies with the monitoring alternative in paragraph 
(g) of this section.
    (iv) Secondary flares that receive gas diverted from the primary 
flare. In the event of a discharge from the secondary flare, the sulfur 
content measured by the sulfur monitor on the primary flare should be 
used to calculate SO2 emissions, regardless of whether or not 
the monitoring alternative in paragraph (g) of this section is selected 
for the secondary flare.
    (f) Flow monitoring for flares. Except as provided in paragraphs 
(f)(2) and (h) of this section, the owner or operator of an affected 
flare subject to Sec. 60.103a(c) through (e) shall install, operate, 
calibrate and maintain, in accordance with the specifications in 
paragraph (f)(1) of this section, a CPMS to measure and record the flow 
rate of gas discharged to the flare. If a flow monitor is not already in 
place, the owner or operator of a modified flare shall comply with the 
requirements of this paragraph by no later than November 11, 2015 or 
upon startup of the modified flare, whichever is later.
    (1) The owner or operator shall install, calibrate, operate and 
maintain each flow monitor according to the manufacturer's procedures 
and specifications and the following requirements.
    (i) Locate the monitor in a position that provides a representative 
measurement of the total gas flow rate.

0.1 to 1 feet per second and an accuracy of 5 
percent of the flow rate for velocities greater than 1 feet per second.
    (iii) Use a flow monitor that is maintainable online, is able to 
continuously correct for temperature and pressure and is able to record 
flow in standard conditions (as defined in Sec. 60.2) over one-minute 
averages.
    (iv) At least quarterly, perform a visual inspection of all 
components of the monitor for physical and operational integrity and all 
electrical connections for oxidation and galvanic corrosion if the flow 
monitor is not equipped with a redundant flow sensor.
    (v) Recalibrate the flow monitor in accordance with the 
manufacturer's

[[Page 415]]

procedures and specifications biennially (every two years) or at the 
frequency specified by the manufacturer.
    (2) Emergency flares, secondary flares and flares equipped with 
flare gas recovery systems designed, sized and operated to capture all 
flows except those resulting from startup, shutdown or malfunction are 
not required to install continuous flow monitors; provided, however, 
that for any such flare, the owner or operator shall comply with the 
monitoring alternative in paragraph (g) of this section.
    (g) Alternative monitoring for certain flares equipped with water 
seals. The owner or operator of an affected flare subject to Sec.

flare, a secondary flare or a flare equipped with a flare gas recovery 
system designed, sized and operated to capture all flows except those 
resulting from startup, shutdown or malfunction may, as an alternative 
to the sulfur and flow monitoring requirements of paragraphs (e) and (f) 
of this section, install, operate, calibrate and maintain, in accordance 
with the requirements in paragraphs (g)(1) through (7) of this section, 
a CPMS to measure and record the pressure in the flare gas header 
between the knock-out pot and water seal and to measure and record the 
water seal liquid level. If the required monitoring systems are not 
already in place, the owner or operator of a modified flare shall comply 
with the requirements of this paragraph by no later than November 11, 
2015 or upon startup of the modified flare, whichever is later.
    (1) Locate the pressure sensor(s) in a position that provides a 
representative measurement of the pressure and locate the liquid seal 
level monitor in a position that provides a representative measurement 
of the water column height.

    (5) Conduct calibration checks any time the pressure sensor exceeds 
the manufacturer's specified maximum operating pressure range or install 
a new pressure sensor.
    (6) In a cascaded flare system that employs multiple secondary 
flares, pressure and liquid level monitoring is required only on the 
first secondary flare in the system (i.e., the secondary flare with the 
lowest pressure release set point).
    (7) This alternative monitoring option may be elected only for 
flares with four or fewer pressure exceedances required to be reported 
under Sec. 60.108a(d)(5) (``reportable pressure exceedances'') in any 
365 consecutive calendar days. Following the fifth reportable pressure 
exceedance in a 365-day period, the owner or operator must comply with

as specified in paragraphs (i)(1) through (5) of this section. Determine 
a rolling 3-hour or a rolling daily average as the arithmetic average of 
the applicable 1-hour averages (e.g., a rolling 3-hour average is the 
arithmetic average of three contiguous 1-hour averages). Determine a 
rolling 30-day or a rolling 365-day average as the arithmetic average of 
the

[[Page 416]]

applicable daily averages (e.g., a rolling 30-day average is the 
arithmetic average of 30 contiguous daily averages).

combustion device or sulfur recovery plant and discharges to an affected 
flare in excess of 500,000 scf above baseline in any 24-hour period as 
required by Sec. 60.103a(c). If the monitoring alternative provided in 
Sec. 60.107a(g) is selected, the owner or operator shall record any 
instance when the flare gas line pressure exceeds the water seal liquid 
depth, except for periods attributable to compressor staging that do not 
exceed the staging time specified in Sec. 60.103a(a)(3)(vii)(C). The 
following information shall be recorded no later than 45 days following 
the end of a discharge exceeding the thresholds:
    (i) A description of the discharge.
    (ii) The date and time the discharge was first identified and the 
duration of the discharge.
    (iii) The measured or calculated cumulative quantity of gas 
discharged over the discharge duration. If the discharge duration 
exceeds 24 hours, record the discharge quantity for each 24-hour period. 
For a flare, record the measured or calculated cumulative quantity of 
gas discharged to the flare over the discharge duration. If the 
discharge duration exceeds 24 hours, record the quantity of gas 
discharged to the flare for each 24-hour period. Engineering 
calculations are allowed for fuel gas combustion devices, but are not 
allowed for flares, except for those complying with the alternative 
monitoring requirements in Sec. 60.107a(g).

Sec. 60.113a  Testing and procedures.

    (a) Except as provided in Sec. 60.8(b) compliance with the standard 
prescribed in Sec. 60.112a shall be determined as follows or in 
accordance with an equivalent procedure as provided in Sec. 60.114a.
    (1) The owner or operator of each storage vessel to which this 
subpart applies which has an external floating roof shall meet the 
following requirements:

[[Page 424]]

    (i) Determine the gap areas and maximum gap widths between the 
primary seal and the tank wall and between the secondary seal and the 
tank wall according to the following frequency:
    (A) For primary seals, gap measurements shall be performed within 60 
days of the initial fill with petroleum liquid and at least once every 
five years thereafter. All primary seal inspections or gap measurements 
which require the removal or dislodging of the secondary seal shall be 
accomplished as rapidly as possible and the secondary seal shall be 
replaced as soon as possible.
    (B) For secondary seals, gap measurements shall be performed within 
60 days of the initial fill with petroleum liquid and at least once 
every year thereafter.
    (C) If any storage vessel is out of service for a period of one year 
or more, subsequent refilling with petroleum liquid shall be considered 
initial fill for the purposes of paragraphs (a)(1)(i)(A) and 
(a)(1)(i)(B) of this section.
    (D) Keep records of each gap measurement at the plant for a period 
of at least 2 years following the date of measurement. Each record shall 
identify the vessel on which the measurement was performed and shall 
contain the date of the seal gap measurement, the raw data obtained in 
the measurement process required by paragraph (a)(1)(ii) of this section 
and the calculation required by paragraph (a)(1)(iii) of this section.
    (E) If either the seal gap calculated in accord with paragraph 
(a)(1)(iii) of this section or the measured maximum seal gap exceeds the 
limitations specified by Sec. 60.112a of this subpart, a report shall 
be furnished to the Administrator within 60 days of the date of 
measurements. The report shall identify the vessel and list each reason 
why the vessel did not meet the specifications of Sec. 60.112a. The 
report shall also describe the actions necessary to bring the storage 
vessel into compliance with the specifications of Sec. 60.112a.
    (ii) Determine gap widths in the primary and secondary seals 
individually by the following procedures:
    (A) Measure seal gaps, if any, at one or more floating roof levels 
when the roof is floating off the roof leg supports.
    (B) Measure seal gaps around the entire circumference of the tank in 
each place where a \1/8\ diameter uniform probe passes freely 
(without forcing or binding against seal) between the seal and the tank 
wall and measure the circumferential distance of each such location.
    (C) The total surface area of each gap described in paragraph 
(a)(1)(ii)(B) of this section shall be determined by using probes of 
various widths to accurately measure the actual distance from the tank 
wall to the seal and multiplying each such width by its respective 
circumferential distance.
    (iii) Add the gap surface area of each gap location for the primary 
seal and the secondary seal individually. Divide the sum for each seal 
by the nominal diameter of the tank and compare each ratio to the 
appropriate ratio in the standard in Sec. 60.112a(a)(1)(i) and Sec. 
60.112a(a)(1)(ii).
    (iv) Provide the Administrator 30 days prior notice of the gap 
measurement to afford the Administrator the opportunity to have an 
observer present.
    (2) The owner or operator of each storage vessel to which this 
subpart applies which has a vapor recovery and return or disposal system 
shall provide the following information to the Administrator on or 
before the date on which construction of the storage vessel commences:
    (i) Emission data, if available, for a similar vapor recovery and 
return or disposal system used on the same type of storage vessel, which 
can be used to determine the efficiency of the system. A complete 
description of the emission measurement method used must be included.
    (ii) The manufacturer's design specifications and estimated emission 
reduction capability of the system.
    (iii) The operation and maintenance plan for the system.
    (iv) Any other information which will be useful to the Administrator 
in evaluating the effectiveness of the system in reducing VOC emissions.

Sec. 60.114a  Alternative means of emission limitation.

    (a) If, in the Administrator's judgment, an alternative means of 
emission limitation will achieve a reduction in emissions at least 
equivalent to the reduction in emissions achieved by any requirement in 
Sec. 60.112a, the Administrator will publish in the Federal Register a 
notice permitting the use of the alternative means for purposes of 
compliance with that requirement.
    (b) Any notice under paragraph (a) of this section will be published 
only after notice and an opportunity for a hearing.
    (c) Any person seeking permission under this section shall submit to 
the Administrator a written application including:
    (1) An actual emissions test that uses a full-sized or scale-model 
storage vessel that accurately collects and measures all VOC emissions 
from a given control device and that accurately simulates wind and 
accounts for other emission variables such as temperature and barometric 
pressure.
    (2) An engineering evaluation that the Administrator determines is 
an accurate method of determining equivalence.
    (d) The Administrator may condition the permission on requirements 
that may be necessary to ensure operation and maintenance to achieve the 
same emissions reduction as specified in Sec. 60.112a.
    (e) The primary vapor-mounted seal in the ``Volume-Maximizing Seal'' 
manufactured by R.F.I. Services Corporation is approved as equivalent to 
the vapor-mounted seal required by Sec. 60.112a(a)(1)(i) and must meet 
the gap criteria specified in Sec. 60.112a(a)(1)(i)(B). There shall be 
no gaps between the tank wall and any secondary seal used in conjunction 
with the primary seal in the ``Volume-Maximizing Seal''.

or operator subject to this subpart shall maintain a record of the 
petroleum liquid stored, the period of storage, and the maximum true 
vapor pressure of that liquid during the respective storage period.
    (b) Available data on the typical Reid vapor pressure and the 
maximum expected storage temperature of the stored product may be used 
to determine the maximum true vapor pressure from nomographs contained 
in API Bulletin 2517, unless the Administrator specifically requests 
that the liquid be sampled, the actual storage temperature determined, 
and the Reid vapor pressure determined from the sample(s).
    (c) The true vapor pressure of each type of crude oil with a Reid 
vapor pressure less than 13.8 kPa (2.0 psia) or whose physical 
properties preclude determination by the recommended method is to be 
determined from available data and recorded if the estimated true vapor 
pressure is greater than 6.9 kPa (1.0 psia).
    (d) The following are exempt from the requirements of this section:
    (1) Each owner or operator of each storage vessel storing a 
petroleum liquid with a Reid vapor pressure of less than 6.9 kPa (1.0 
psia) provided the maximum true vapor pressure does not exceed 6.9 kPa 
(1.0 psia).
    (2) The owner or operator of each storage vessel equipped with a 
vapor recovery and return or disposal system in accordance with the 
requirements of Sec. 60.112a(a)(3) and (b), or a closed vent system and

Sec. 60.113b  Testing and procedures.

    The owner or operator of each storage vessel as specified in Sec. 
60.112b(a) shall meet the requirements of paragraph (a), (b), or (c) of 
this section. The applicable paragraph for a particular storage vessel 
depends on the control

[[Page 431]]

equipment installed to meet the requirements of Sec. 60.112b.
    (a) After installing the control equipment required to meet Sec. 
60.112b(a)(1) (permanently affixed roof and internal floating roof), 
each owner or operator shall:
    (1) Visually inspect the internal floating roof, the primary seal, 
and the secondary seal (if one is in service), prior to filling the 
storage vessel with VOL. If there are holes, tears, or other openings in 
the primary seal, the secondary seal, or the seal fabric or defects in 
the internal floating roof, or both, the owner or operator shall repair 
the items before filling the storage vessel.
    (2) For Vessels equipped with a liquid-mounted or mechanical shoe 
primary seal, visually inspect the internal floating roof and the 
primary seal or the secondary seal (if one is in service) through 
manholes and roof hatches on the fixed roof at least once every 12 
months after initial fill. If the internal floating roof is not resting 
on the surface of the VOL inside the storage vessel, or there is liquid 
accumulated on the roof, or the seal is detached, or there are holes or 
tears in the seal fabric, the owner or operator shall repair the items 
or empty and remove the storage vessel from service within 45 days. If a 
failure that is detected during inspections required in this paragraph 
cannot be repaired within 45 days and if the vessel cannot be emptied 
within 45 days, a 30-day extension may be requested from the 
Administrator in the inspection report required in Sec. 60.115b(a)(3). 
Such a request for an extension must document that alternate storage 
capacity is unavailable and specify a schedule of actions the company 
will take that will assure that the control equipment will be repaired 
or the vessel will be emptied as soon as possible.
    (3) For vessels equipped with a double-seal system as specified in 
Sec. 60.112b(a)(1)(ii)(B):
    (i) Visually inspect the vessel as specified in paragraph (a)(4) of 
this section at least every 5 years; or
    (ii) Visually inspect the vessel as specified in paragraph (a)(2) of 
this section.
    (4) Visually inspect the internal floating roof, the primary seal, 
the secondary seal (if one is in service), gaskets, slotted membranes 
and sleeve seals (if any) each time the storage vessel is emptied and 
degassed. If the internal floating roof has defects, the primary seal 
has holes, tears, or other openings in the seal or the seal fabric, 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 liquid surfaces 
from the atmosphere, or the slotted membrane has more than 10 percent 
open area, the owner or operator shall repair the items as necessary so 
that none of the conditions specified in this paragraph exist before 
refilling the storage vessel with VOL. In no event shall inspections 
conducted in accordance with this provision occur at intervals greater 
than 10 years in the case of vessels conducting the annual visual 
inspection as specified in paragraphs (a)(2) and (a)(3)(ii) of this 
section and at intervals no greater than 5 years in the case of vessels 
specified in paragraph (a)(3)(i) of this section.
    (5) Notify the Administrator in writing at least 30 days prior to 
the filling or refilling of each storage vessel for which an inspection 
is required by paragraphs (a)(1) and (a)(4) of this section to afford 
the Administrator the opportunity to have an observer present. If the 
inspection required by paragraph (a)(4) of this section is not planned 
and the owner or operator could not have known about the inspection 30 
days in advance or refilling the tank, the owner or operator shall 
notify the Administrator at least 7 days prior to the refilling of the 
storage vessel. Notification shall be made by telephone immediately 
followed by written documentation demonstrating why the inspection was 
unplanned. Alternatively, this notification including the written 
documentation may be made in writing and sent by express mail so that it 
is received by the Administrator at least 7 days prior to the refilling.
    (b) After installing the control equipment required to meet Sec. 
60.112b(a)(2) (external floating roof), the owner or operator shall:

[[Page 432]]

    (1) Determine the gap areas and maximum gap widths, between the 
primary seal and the wall of the storage vessel and between the 
secondary seal and the wall of the storage vessel according to the 
following frequency.
    (i) Measurements of gaps between the tank wall and the primary seal 
(seal gaps) shall be performed during the hydrostatic testing of the 
vessel or within 60 days of the initial fill with VOL and at least once 
every 5 years thereafter.
    (ii) Measurements of gaps between the tank wall and the secondary 
seal shall be performed within 60 days of the initial fill with VOL and 
at least once per year thereafter.
    (iii) If any source ceases to store VOL for a period of 1 year or 
more, subsequent introduction of VOL into the vessel shall be considered 
an initial fill for the purposes of paragraphs (b)(1)(i) and (b)(1)(ii) 
of this section.
    (2) Determine gap widths and areas in the primary and secondary 
seals individually by the following procedures:
    (i) Measure seal gaps, if any, at one or more floating roof levels 
when the roof is floating off the roof leg supports.
    (ii) Measure seal gaps around the entire circumference of the tank 
in each place where a 0.32-cm diameter uniform probe passes freely 
(without forcing or binding against seal) between the seal and the wall 
of the storage vessel and measure the circumferential distance of each 
such location.
    (iii) The total surface area of each gap described in paragraph 
(b)(2)(ii) of this section shall be determined by using probes of 
various widths to measure accurately the actual distance from the tank 
wall to the seal and multiplying each such width by its respective 
circumferential distance.
    (3) Add the gap surface area of each gap location for the primary 
seal and the secondary seal individually and divide the sum for each 
seal by the nominal diameter of the tank and compare each ratio to the 
respective standards in paragraph (b)(4) of this section.
    (4) Make necessary repairs or empty the storage vessel within 45 
days of identification in any inspection for seals not meeting the 
requirements listed in (b)(4) (i) and (ii) of this section:
    (i) The accumulated area of gaps between the tank wall and the 
mechanical shoe or liquid-mounted primary seal shall not exceed 212 
cm\2\ per meter of tank diameter, and the width of any portion of any 
gap shall not exceed 3.81 cm.
    (A) One end of the mechanical shoe is to extend into the stored 
liquid, and the other end is to extend a minimum vertical distance of 61 
cm above the stored liquid surface.
    (B) There are to be no holes, tears, or other openings in the shoe, 
seal fabric, or seal envelope.
    (ii) The secondary seal is to meet the following requirements:
    (A) The secondary seal is to be installed above the primary seal so 
that it completely covers the space between the roof edge and the tank 
wall except as provided in paragraph (b)(2)(iii) of this section.
    (B) The accumulated area of gaps between the tank wall and the 
secondary seal shall not exceed 21.2 cm\2\ per meter of tank diameter, 
and the width of any portion of any gap shall not exceed 1.27 cm.
    (C) There are to be no holes, tears, or other openings in the seal 
or seal fabric.
    (iii) If a failure that is detected during inspections required in 
paragraph (b)(1) of Sec. 60.113b(b) cannot be repaired within 45 days 
and if the vessel cannot be emptied within 45 days, a 30-day extension 
may be requested from the Administrator in the inspection report 
required in Sec. 60.115b(b)(4). Such extension request must include a 
demonstration of unavailability of alternate storage capacity and a 
specification of a schedule that will assure that the control equipment 
will be repaired or the vessel will be emptied as soon as possible.
    (5) Notify the Administrator 30 days in advance of any gap 
measurements required by paragraph (b)(1) of this section to afford the 
Administrator the opportunity to have an observer present.
    (6) Visually inspect the external floating roof, the primary seal, 
secondary seal, and fittings each time the vessel is emptied and 
degassed.
    (i) If the external floating roof has defects, the primary seal has 
holes, tears, or other openings in the seal or

[[Page 433]]

the seal fabric, or the secondary seal has holes, tears, or other 
openings in the seal or the seal fabric, the owner or operator shall 
repair the items as necessary so that none of the conditions specified 
in this paragraph exist before filling or refilling the storage vessel 
with VOL.
    (ii) For all the inspections required by paragraph (b)(6) of this 
section, the owner or operator shall notify the Administrator in writing 
at least 30 days prior to the filling or refilling of each storage 
vessel to afford the Administrator the opportunity to inspect the 
storage vessel prior to refilling. If the inspection required by 
paragraph (b)(6) of this section is not planned and the owner or 
operator could not have known about the inspection 30 days in advance of 
refilling the tank, the owner or operator shall notify the Administrator 
at least 7 days prior to the refilling of the storage vessel. 
Notification shall be made by telephone immediately followed by written 
documentation demonstrating why the inspection was unplanned. 
Alternatively, this notification including the written documentation may 
be made in writing and sent by express mail so that it is received by 
the Administrator at least 7 days prior to the refilling.
    (c) The owner or operator of each source that is equipped with a 
closed vent system and control device as required in Sec. 60.112b 
(a)(3) or (b)(2) (other than a flare) is exempt from Sec. 60.8 of the 
General Provisions and shall meet the following requirements.
    (1) Submit for approval by the Administrator as an attachment to the 
notification required by Sec. 60.7(a)(1) or, if the facility is exempt 
from Sec. 60.7(a)(1), as an attachment to the notification required by 
Sec. 60.7(a)(2), an operating plan containing the information listed 
below.
    (i) Documentation demonstrating that the control device will achieve 
the required control efficiency during maximum loading conditions. This 
documentation is to include a description of the gas stream which enters 
the control device, including flow and VOC content under varying liquid 
level conditions (dynamic and static) and manufacturer's design 
specifications for the control device. If the control device or the 
closed vent capture system receives vapors, gases, or liquids other than 
fuels from sources that are not designated sources under this subpart, 
the efficiency demonstration is to include consideration of all vapors, 
gases, and liquids received by the closed vent capture system and 
control device. If an enclosed combustion device with a minimum 
residence time of 0.75 seconds and a minimum temperature of 816 [deg]C 
is used to meet the 95 percent requirement, documentation that those 
conditions will exist is sufficient to meet the requirements of this 
paragraph.
    (ii) A description of the parameter or parameters to be monitored to 
ensure that the control device will be operated in conformance with its 
design and an explanation of the criteria used for selection of that 
parameter (or parameters).
    (2) Operate the closed vent system and control device and monitor 
the parameters of the closed vent system and control device in 
accordance with the operating plan submitted to the Administrator in 
accordance with paragraph (c)(1) of this section, unless the plan was 
modified by the Administrator during the review process. In this case, 
the modified plan applies.
    (d) The owner or operator of each source that is equipped with a 
closed vent system and a flare to meet the requirements in Sec. 60.112b 
(a)(3) or (b)(2) shall meet the requirements as specified in the general 
control device requirements, Sec. 60.18 (e) and (f).

Administrator.
    (f) The owner or operator of each vessel storing a waste mixture of 
indeterminate or variable composition shall be subject to the following 
requirements.
    (1) Prior to the initial filling of the vessel, the highest maximum 
true vapor pressure for the range of anticipated liquid compositions to 
be stored will be determined using the methods described in paragraph 
(e) of this section.
    (2) For vessels in which the vapor pressure of the anticipated 
liquid composition is above the cutoff for monitoring but below the 
cutoff for controls as defined in Sec. 60.112b(a), an initial physical 
test of the vapor pressure is required; and a physical test at least 
once every 6 months thereafter is required as determined by the 
following methods:
    (i) ASTM D2879-83, 96, or 97 (incorporated by reference--see Sec. 
60.17); or
    (ii) ASTM D323-82 or 94 (incorporated by reference--see Sec. 
60.17); or
    (iii) As measured by an appropriate method as approved by the 
Administrator.
    (g) The owner or operator of each vessel equipped with a closed vent 
system and control device meeting the specification of Sec. 60.112b or 
with emissions reductions equipment as specified in 40 CFR 65.42(b)(4),

specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.142a as follows:
    (1) Start and end times of each steel production cycle during each 
run shall be recorded (see Sec. 60.145a (c) and (d) for the definitions 
of start and end times of a cycle).
    (2) Method 5 shall be used to determine the particulate matter 
concentration. Sampling shall be conducted only during the steel 
production cycle and for a sufficient number of steel production cycles 
to obtain a total sample volume of at least 5.67 dscm (200 dscf) for 
each run.
    (3) Method 9 and the procedures of Sec. 60.11 shall be used to 
determine opacity, except sections 2.4 and 2.5 of Method 9 shall be 
replaced with the following instructions for recording observations and 
reducing data:
    (i) Section 2.4. Opacity observations shall be recorded to the 
nearest 5 percent at 15-second intervals. During the initial performance 
test conducted pursuant to Sec. 60.8, observations shall be made and 
recorded in this manner for a minimum of three steel production cycles. 
During any subsequent compliance test, observations may be made for any 
number of steel production cycles, although, where conditions permit, 
observations will generally be made for a minimum of three steel 
production cycles.
    (ii) Section 2.5. Opacity shall be determined as an average of 12 
consecutive observations recorded at 15-second intervals. For each steel 
production cycle, divide the observations recorded into sets of 12 
consecutive observations. Sets need not be consecutive in time, and in

owner or operator shall conduct an initial test as follows:
    (1) For devices that monitor and record the exhaust ventilation 
rate, compare velocity readings recorded by the monitoring device 
against the velocity readings obtained by Method 2. Take Method 2 
readings at a point or points that would properly characterize the 
monitoring device's performance and that would adequately reflect the 
various rates of exhaust ventilation. Obtain readings at sufficient 
intervals to obtain 12 pairs of readings for each duct of the secondary 
emission capture system. Compare the averages of the two sets to 
determine whether the monitoring device velocity is within 10 percent of the Method 2 average.
    (2) For devices that monitor the level of exhaust ventilation and 
record only step changes when a set point rate is reached, compare step 
changes recorded by the monitoring device against the velocity readings 
obtained by Method 2. Take Method 2 readings

[[Page 444]]

at a point or points that would properly characterize the performance of 
the monitoring device and that would adequately reflect the various 
rates of exhaust ventilation. Obtain readings at sufficient intervals to 
obtain 12 pairs of readings for each duct of the secondary emission 
capture system. Compare the averages of the two sets to determine 
whether the monitoring device step change is within 10 percent of the setpoint rate.
    (d) To comply with Sec. 60.143a(d) or (e), the owner or operator 
shall use the monitoring device of Sec. 60.143a(a) to determine the 
exhaust ventilation rates or levels during the particulate matter runs.

Sec. 60.145a  Compliance provisions.

    (a) When determining compliance with mass and visible emission 
limits specified in Sec. 60.142a(a) (2) and (3), the owner or operator 
of a BOPF shop that normally operates two furnaces with overlapping 
cycles may elect to operate only one furnace. If an owner or operator 
chooses to shut down one furnace, he shall be allowed a reasonable time 
period to adjust his production schedule before the compliance tests are 
conducted. The owner or operator of an affected facility may also elect 
to suspend shop operations not subject to this subpart during compliance 
testing.
    (b) During compliance testing for mass and visible emission 
standards, if an owner or operator elects to shut down one furnace in a 
shop that normally operates two furnaces with overlapping cycles, the 
owner or operator shall operate the secondary emission control system 
for the furnace being tested at exhaust ventilation rates or levels for 
each duct of the secondary emission control system that are appropriate 
for single-furnace operation. Following the compliance test, the owner 
or operator shall operate the secondary emission control system at 
exhaust ventilation rates or levels for each duct of the system that are 
no lower than 90 percent of the exhaust ventilation values established 
during the most recent compliance test.
    (c) For the purpose of determining compliance with visible and mass 
emission standards, a steel production cycle begins when the scrap or 
hot metal is charged to the vessel (whichever operation occurs first) 
and terminates 3 minutes after slag is emptied from the vessel into the 
slag pot. Consecutive steel production cycles are not required for the 
purpose of determining compliance. Where a hot metal transfer or 
skimming station is an affected facility, the steel production cycle 
also includes the hot metal transfer or skimming operation for the next 
steel production cycle for the affected vessel. Visible emission 
observations for both hot metal transfer and skimming operations begin 
with the start of the operation and terminate 3 minutes after completion 
of the operation.
    (d) For the purpose of determining compliance with visible emission 
standards specified in Sec. 60.142a(a) (1) and (3), the starting and 
stopping times of regulated process operations shall be determined and 
the starting and stopping times of visible emissions data sets shall be 
determined accordingly.
    (e) To determine compliance with Sec. 60.142a(a)(1), select the 
data sets yielding the highest and second highest 3-minute average 
opacities for each steel production cycle. Compliance is achieved if the 
highest 3-minute average for each cycle observed is less than 20 percent 
and the second highest 3-minute average is 10 percent or less.
    (f) To determine compliance with Sec. 60.142(a)(2), determine the 
concentration of particulate matter in exhaust gases exiting the 
secondary emission collection device with Method 5. Compliance is 
achieved if the concentration of particulate matter does not exceed 23 
mg/dscm (0.010 gr/dscf).
    (g) To determine compliance with Sec. 60.142a(a)(3), construct 
consecutive 3-minute averages for each steel production cycle. 
Compliance is achieved if no 3-minute average is more than 5 percent.

Performance Specification 1 in 40 CFR part 60, appendix B.
    (ii) The owner or operator must adjust the zero and span whenever 
the 24-

[[Page 477]]

hour zero drift or 24-hour span drift exceeds 4 percent opacity. The 
COMS must allow for the amount of excess zero and span drift measured at 
the 24-hour interval checks to be recorded and quantified. The optical 
surfaces exposed to the effluent gases must be cleaned prior to 
performing the zero and span drift adjustments, except for systems using 
automatic zero adjustments. For systems using automatic zero 
adjustments, the optical surfaces must be cleaned when the cumulative 
automatic zero compensation exceeds 4 percent opacity.
    (iii) The owner or operator must apply a method for producing a 
simulated zero opacity condition and an upscale (span) opacity condition 
using a certified neutral density filter or other related technique to 
produce a known obscuration of the light beam. All procedures applied 
must provide a system check of the analyzer internal optical surfaces 
and all electronic circuitry including the lamp and photodetector 
assembly.
    (iv) Except during periods of system breakdowns, repairs, 
calibration checks, and zero and span adjustments, the COMS must be in 
continuous operation and must complete a minimum of one cycle of 
sampling and analyzing for each successive 10-second period and one 
cycle of data recording for each successive 6-minute period.
    (v) The owner or operator must reduce all data from the COMS to 6-
minute averages. Six-minute opacity averages must be calculated from 36 
or more data points equally spaced over each 6-minute period. Data 
recorded during periods of system breakdowns, repairs, calibration 
checks, and zero and span adjustments must not be included in the data 
averages. An arithmetic or integrated average of all data may be used.
    (h) The owner or operator of each affected coal truck dump operation 
that commenced construction, reconstruction, or modification after April 
28, 2008, must meet the requirements specified in paragraphs (h)(1) 
through (3) of this section.
    (1) Conduct an initial performance test using Method 9 of appendix 
A-4 of this part according to the requirements in paragraphs (h)(1)(i) 
and(ii).
    (i) Opacity readings shall be taken during the duration of three 
separate truck dump events. Each truck dump event commences when the 
truck bed begins to elevate and concludes when the truck bed returns to 
a horizontal position.
    (ii) Compliance with the applicable opacity limit is determined by 
averaging all 15-second opacity readings made during the duration of 
three separate truck dump events.
    (2) Conduct monthly visual observations of all process and control 
equipment. If any deficiencies are observed, the necessary maintenance 
must be performed as expeditiously as possible.

and 2 of appendix A to this part.
    (d) When performance tests are conducted under the provisions of 
Sec. 60.8 of this part to demonstrate compliance with the standards 
under Sec. Sec. 60.262(a) (4) and (5), the volumetric flow rate through 
each separately ducted hood of the capture system must be determined 
using the monitoring device required under paragraph (c) of this 
section. The volumetric flow rates must be determined for furnace power 
input levels at 50 and 100 percent of the nominal rated capacity of the 
electric submerged arc furnace. At all times the electric submerged arc 
furnace is operated, the owner or operator shall maintain the volumetric 
flow rate at or above the appropriate levels for that furnace power 
input level determined during the most recent performance test. If 
emissions due to tapping are captured and ducted separately from 
emissions of the electric submerged arc furnace, during each tapping 
period the owner or operator shall maintain the exhaust flow rates 
through the capture system over the tapping station at or above the 
levels established during the most recent performance test. Operation at 
lower flow rates may be considered by the Administrator to be 
unacceptable operation and maintenance of the affected facility. The 
owner or operator may request that these flow rates be reestablished by 
conducting new performance tests under Sec. 60.8 of this part.
    (e) The owner or operator may as an alternative to paragraph (c) of 
this section determine the volumetric flow rate through each fan of the 
capture system from the fan power consumption, pressure drop across the 
fan and the fan performance curve. Only data specific to the operation 
of the affected electric submerged arc furnace are acceptable for 
demonstration of compliance with the requirements of this paragraph. The 
owner or operator shall maintain on file a permanent record of the fan 
performance curve (prepared for a specific temperature) and shall:
    (1) Install, calibrate, maintain, and operate a device to 
continuously measure and record the power consumption of the fan motor 
(measured in kilowatts), and
    (2) Install, calibrate, maintain, and operate a device to 
continuously measure and record the pressure drop across the fan. The 
fan power consumption and pressure drop measurements must be 
synchronized to allow real time comparisions of the data. The monitoring 
devices must have an accuracy of 5 percent over 
their normal operating ranges.
    (f) The volumetric flow rate through each fan of the capture system 
must be determined from the fan power consumption, fan pressure drop, 
and fan performance curve specified under paragraph (e) of this section, 
during any performance test required under Sec. 60.8 to demonstrate 
compliance with the standards under Sec. Sec. 60.262(a)(4) and (5). The 
owner or operator shall determine the volumetric flow rate at a 
representative temperature for furnace power input levels of 50 and 100 
percent of the nominal rated capacity of the electric submerged arc 
furnace. At all times the electric submerged arc furnace is operated, 
the owner or operator shall maintain the fan power consumption and fan 
pressure drop at levels such that the volumetric flow rate is at or 
above the levels established during

[[Page 486]]

the most recent performance test for that furnace power input level. If 
emissions due to tapping are captured and ducted separately from 
emissions of the electric submerged arc furnace, during each tapping 
period the owner or operator shall maintain the fan power consumption 
and fan pressure drop at levels such that the volumetric flow rate is at 
or above the levels established during the most recent performance test. 
Operation at lower flow rates may be considered by the Administrator to 
be unacceptable operation and maintenance of the affected facility. The 
owner or operator may request that these flow rates be reestablished by 
conducting new performance tests under Sec. 60.8. The Administrator may 
require the owner or operator to verify the fan performance curve by 
monitoring necessary fan operating parameters and determining the gas 
volume moved relative to Methods 1 and 2 of appendix A to this part.
    (g) All monitoring devices required under paragraphs (c) and (e) of 
this section are to be checked for calibration annually in accordance 
with the procedures under Sec. 60.13(b).



Sec. 60.266  Test methods and procedures.

    (a) During any performance test required in Sec. 60.8, the owner or 
operator shall not allow gaseous diluents to be added to the effluent 
gas stream after the fabric in an open pressurized fabric filter 
collector unless the total gas volume flow from the collector is 
accurately determined and considered in the determination of emissions.
    (b) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (c) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.262 as follows:
    (1) The emission rate (E) of particulate matter shall be computed 
for each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.012

where:

E = emission rate of particulate matter, kg/MW-hr (1b/MW-hr).
n = total number of exhaust streams at which emissions are quantified.
csi = concentration of particulate matter from exhaust stream 
          ``i'', g/dscm (gr/dscf).
Qsdi = volumetric flow rate of effluent gas from exhaust 
          stream ``i'', dscm/hr (dscf/hr).
P = average furnace power input, MW.
K = conversion factor, 1000 g/kg (7000 gr/lb).

    (2) Method 5 shall be used to determine the particulate matter 
concentration (csi) and volumetric flow rate 
(Qsdi) of the effluent gas, except that the heating systems 
specified in sections 2.1.2 and 2.1.6 are not to be used when the carbon 
monoxide content of the gas stream exceeds 10 percent by volume, dry 
basis. If a flare is used to comply with Sec. 60.263, the sampling site 
shall be upstream of the flare. The sampling time shall include an 
integral number of furnace cycles.
    (i) When sampling emissions from open electric submerged arc 
furnaces with wet scrubber control devices, sealed electric submerged 
arc furnaces, or semienclosed electric arc furnaces, the sampling time 
and sample volume for each run shall be at least 60 minutes and 1.80 
dscm (63.6 dscf).
    (ii) When sampling emissions from other types of installations, the 
sampling time and sample volume for each run shall be at least 200 
minutes and 5.66 dscm (200 dscf).
    (3) The measurement device of Sec. 60.265(b) shall be used to 
determine the average furnace power input (P) during each run.
    (4) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (5) The emission rate correction factor, integrated sampling 
procedure of Method 3B shall be used to determine the CO concentration. 
The sample shall be taken simultaneously with each particulate matter 
sample.
    (d) During the particulate matter run, the maximum open hood area 
(in hoods with segmented or otherwise moveable sides) under which the 
process is expected to be operated and remain in compliance with all 
standards shall be recorded. Any future operation of the hooding system 
with open areas

[[Page 487]]

in excess of the maximum is not permitted.
    (e) To comply with Sec. 60.265 (d) or (f), the owner or operator 
shall use the monitoring devices in Sec. 60.265 (c) or (e) to make the 
required measurements as determined during the performance test.

Sec. 60.272  Standard for particulate matter.

    (a) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere from an electric arc furnace any gases which:
    (1) Exit from a control device and contain particulate matter in 
excess of 12 mg/dscm (0.0052 gr/dscf).
    (2) Exit from a control device and exhibit three percent opacity or

this section shall apply when the roof is opened and shall continue to 
apply for the length of time defined by the charging and/or tapping 
periods.
    (b) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere from dust-handling equipment any gases which exhibit 10

64 FR 10109, Mar. 2, 1999]



Sec. 60.273  Emission monitoring.

    (a) A continuous monitoring system for the measurement of the 
opacity of emissions discharged into the atmosphere from the control 
device(s) shall be installed, calibrated, maintained, and operated by 
the owner or operator subject to the provisions of this subpart.
    (b) For the purpose of reports under Sec. 60.7(c), all six-minute 
periods during which the average opacity is three percent or greater 
shall indicate a period of excess emission, and shall be reported to the 
Administrator semi-annually.
    (c) A continuous monitoring system for the measurement of the 
opacity of emissions discharged into the atmosphere from the control 
device(s) is not required on any modular, multi-stack, negative-pressure 
or positive-pressure fabric filter if observations of the opacity of the 
visible emissions from the control device are performed by a certified 
visible emission observer; or on any single-stack fabric filter if 
visible emissions from the control device are performed by a certified 
visible emission observer and the owner installs and continuously 
operates a bag leak detection system according to paragraph (e) of this 
section. Visible emission observations shall be conducted at least once 
per day for at least three 6-minute periods when the furnace is 
operating in the melting and refining period. All visible emissions 
observations shall be conducted in accordance with Method 9 of appendix 
A to this part. If visible emissions occur from more than one point, the 
opacity shall be recorded for any points where visible emissions are 
observed. Where it is possible to determine that a number of visible 
emission sites relate to only one incident of

[[Page 489]]

the visible emission, only one set of three 6-minute observations will 
be required. In that case, the Method 9 observations must be made for 
the site of highest opacity that directly relates to the cause (or 
location) of visible emissions observed during a single incident. 
Records shall be maintained of any 6-minute average that is in excess of 
the emission limit specified in Sec. 60.272(a).
    (d) A furnace static pressure monitoring device is not required on 
any EAF equipped with a DEC system if observations of shop opacity are 
performed by a certified visible emission observer as follows: Shop 
opacity observations shall be conducted at least once per day when the 
furnace is operating in the meltdown and refining period. Shop opacity 
shall be determined as the arithmetic average of 24 or more consecutive 
15-second opacity observations of emissions from the shop taken in 
accordance with Method 9. Shop opacity shall be recorded for any 
point(s) where visible emissions are observed in proximity to an 
affected EAF. Where it is possible to determine that a number of visible 
emission sites relate to only one incident of visible emissions, only 
one observation of shop opacity will be required. In this case, the shop 
opacity observations must be made for the site of highest opacity that 
directly relates to the cause (or location) of visible emissions 
observed during a single incident.
    (e) A bag leak detection system must be installed and continuously 
operated on all single-stack fabric filters if the owner or operator 
elects not to install and operate a continuous opacity monitoring system 
as provided for under paragraph (c) of this section. In addition, the 
owner or operator shall meet the visible emissions observation 
requirements in paragraph (c) of this section. The bag leak detection 
system must meet the specifications and requirements of paragraphs 
(e)(1) through (8) of this section.
    (1) The bag leak detection system must be certified by the 
manufacturer to be capable of detecting particulate matter emissions at 
concentrations of 1 milligram per actual cubic meter (0.00044 grains per 
actual cubic foot) or less.
    (2) The bag leak detection system sensor must provide output of 
relative particulate matter loadings and the owner or operator shall 
continuously record the output from the bag leak detection system using 
electronic or other means (e.g., using a strip chart recorder or a data 
logger.)
    (3) The bag leak detection system must be equipped with an alarm 
system that will sound when an increase in relative particulate loading 
is detected over the alarm set point established according to paragraph 
(e)(4) of this section, and the alarm must be located such that it can 
be heard by the appropriate plant personnel.
    (4) For each bag leak detection system required by paragraph (e) of 
this section, the owner or operator shall develop and submit to the 
Administrator or delegated authority, for approval, a site-specific 
monitoring plan that addresses the items identified in paragraphs (i) 
through (v) of this paragraph (e)(4). For each bag leak detection system 
that operates based on the triboelectric effect, the monitoring plan 
shall be consistent with the recommendations contained in the U.S. 
Environmental Protection Agency guidance document ``Fabric Filter Bag 
Leak Detection Guidance'' (EPA-454/R-98-015). The owner or operator 
shall operate and maintain the bag leak detection system according to 
the site-specific monitoring plan at all times. The plan shall describe:
    (i) Installation of the bag leak detection system;
    (ii) Initial and periodic adjustment of the bag leak detection 
system including how the alarm set-point will be established;
    (iii) Operation of the bag leak detection system including quality 
assurance procedures;
    (iv) How the bag leak detection system will be maintained including 
a routine maintenance schedule and spare parts inventory list; and
    (v) How the bag leak detection system output shall be recorded and 
stored.
    (5) The initial adjustment of the system shall, at a minimum, 
consist of establishing the baseline output by adjusting the sensitivity 
(range) and the

[[Page 490]]

averaging period of the device, and establishing the alarm set points 
and the alarm delay time (if applicable).
    (6) Following initial adjustment, the owner or operator shall not 
adjust the averaging period, alarm set point, or alarm delay time 
without approval from the Administrator or delegated authority except as 
provided for in paragraphs (e)(6)(i) and (ii) of this section.
    (i) Once per quarter, the owner or operator may adjust the 
sensitivity of the bag leak detection system to account for seasonal 
effects including temperature and humidity according to the procedures 
identified in the site-specific monitoring plan required under 
paragraphs (e)(4) of this section.
    (ii) If opacities greater than zero percent are observed over four 
consecutive 15-second observations during the daily opacity observations 
required under paragraph (c) of this section and the alarm on the bag 
leak detection system does not sound, the owner or operator shall lower 
the alarm set point on the bag leak detection system to a point where 
the alarm would have sounded during the period when the opacity 
observations were made.
    (7) For negative pressure, induced air baghouses, and positive 
pressure baghouses that are discharged to the atmosphere through a 
stack, the bag leak detection sensor must be installed downstream of the 
baghouse and upstream of any wet scrubber.
    (8) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (f) For each bag leak detection system installed according to 
paragraph (e) of this section, the owner or operator shall initiate 
procedures to determine the cause of all alarms within 1 hour of an 
alarm. Except as provided for in paragraph (g) of this section, the 
cause of the alarm must be alleviated within 3 hours of the time the 
alarm occurred by taking whatever corrective action(s) are necessary. 
Corrective actions may include, but are not limited to the following:
    (1) Inspecting the baghouse for air leaks, torn or broken bags or 
filter media, or any other condition that may cause an increase in 
particulate emissions;
    (2) Sealing off defective bags or filter media;
    (3) Replacing defective bags or filter media or otherwise repairing 
the control device;
    (4) Sealing off a defective baghouse compartment;
    (5) Cleaning the bag leak detection system probe or otherwise 
repairing the bag leak detection system; or
    (6) Shutting down the process producing the particulate emissions.
    (g) In approving the site-specific monitoring plan required in 
paragraph (e)(4) of this section, the Administrator or delegated 
authority may allow owners or operators more than 3 hours to alleviate 
specific conditions that cause an alarm if the owner or operator 
identifies the condition that could lead to an alarm in the monitoring 
plan, adequately explains why it is not feasible to alleviate the 
condition within 3 hours of the time the alarm occurred, and 
demonstrates that the requested additional time will ensure alleviation 
of the condition as expeditiously as practicable.

Sec. 60.274  Monitoring of operations.

    (a) The owner or operator subject to the provisions of this subpart 
shall maintain records daily of the following information:
    (1) Time and duration of each charge;
    (2) Time and duration of each tap;
    (3) All flow rate data obtained under paragraph (b) of this section, 
or equivalent obtained under paragraph (d) of this section; and
    (4) All pressure data obtained under paragraph (f) of this section.
    (b) Except as provided under paragraph (d) of this section, the 
owner or operator subject to the provisions of this subpart shall check 
and record on a once-per-shift basis furnace static pressure (if a DEC 
system is in use, and a furnace static pressure gauge is installed 
according to paragraph (f) of this section) and either: check and record 
the control system fan motor amperes and damper positions on a

[[Page 491]]

once-per-shift basis; install, calibrate, and maintain a monitoring 
device that continuously records the volumetric flow rate through each 
separately ducted hood; or install, calibrate, and maintain a monitoring 
device that continuously records the volumetric flow rate at the control 
device inlet and check and record damper positions on a once-per-shift 
basis. The monitoring device(s) may be installed in any appropriate 
location in the exhaust duct such that reproducible flow rate monitoring 
will result. The flow rate monitoring device(s) shall have an accuracy 
of 10 percent over its normal operating range and 
shall be calibrated according to the manufacturer's instructions. The 
Administrator may require the owner or operator to demonstrate the 
accuracy of the monitoring device(s) relative to Methods 1 and 2 of 
appendix A of this part.
    (c) When the owner or operator of an affected facility is required 
to demonstrate compliance with the standards under Sec. 60.272(a)(3) 
and at any other time that the Administrator may require (under section 
114 of the CAA, as amended) either: the control system fan motor amperes 
and all damper positions, the volumetric flow rate through each 
separately ducted hood, or the volumetric flow rate at the control 
device inlet and all damper positions shall be determined during all 
periods in which a hood is operated for the purpose of capturing 
emissions from the affected facility subject to paragraph (b) of this 
section. The owner or operator may petition the Administrator for 
reestablishment of these parameters whenever the owner or operator can 
demonstrate to the Administrator's satisfaction that the EAF operating 
conditions upon which the parameters were previously established are no 
longer applicable. The values of these parameters as determined during 
the most recent demonstration of compliance shall be maintained at the 
appropriate level for each applicable period. Operation at other than 
baseline values may be subject to the requirements of Sec. 60.276(a).
    (d) The owner or operator may petition the Administrator to approve 
any alternative method that will provide a continuous record of 
operation of each emission capture system.
    (e) The owner or operator shall perform monthly operational status 
inspections of the equipment that is important to the performance of the 
total capture system (i.e., pressure sensors, dampers, and damper 
switches). This inspection shall include observations of the physical 
appearance of the equipment (e.g., presence of hole in ductwork or 
hoods, flow constrictions caused by dents or accumulated dust in 
ductwork, and fan erosion). Any deficiencies shall be noted and proper 
maintenance performed.
    (f) Except as provided for under Sec. 60.273(d), where emissions 
during any phase of the heat time are controlled by use of a direct 
shell evacuation system, the owner or operator shall install, calibrate, 
and maintain a monitoring device that continuously records the pressure 
in the free space inside the EAF. The pressure shall be recorded as 15-
minute integrated averages. The monitoring device may be installed in 
any appropriate location in the EAF or DEC duct prior to the 
introduction of ambient air such that reproducible results will be 
obtained. The pressure monitoring device shall have an accuracy of 
5 mm of water gauge over its normal operating 
range and shall be calibrated according to the manufacturer's 
instructions.
    (g) Except as provided for under Sec. 60.273(d), when the owner or 
operator of an EAF is required to demonstrate compliance with the 
standard under Sec. 60.272(a)(3) and at any other time the 
Administrator may require (under section 114 of the Act, as amended), 
the pressure in the free space inside the furnace shall be determined 
during the meltdown and refining period(s) using the monitoring device 
under paragraph (f) of this section. The owner or operator may petition 
the Administrator for reestablishment of the 15-minute integrated 
average pressure whenever the owner or operator can demonstrate to the 
Administrator's satisfaction that the EAF operating conditions upon 
which the pressures were previously established are no longer 
applicable. The pressure determined during the most recent demonstration 
of compliance shall be maintained at all

[[Page 492]]

times the EAF is operating in a meltdown and refining period. Operation 
at higher pressures may be considered by the Administrator to be 
unacceptable operation and maintenance of the affected facility.
    (h) Where the capture system is designed and operated such that all 
emissions are captured and ducted to a control device, the owner or 
operator shall not be subject to the requirements of this section.
    (i) During any performance test required under Sec. 60.8, and for 
any report thereof required by Sec. 60.276(c) of this subpart or to 
determine compliance with Sec. 60.272(a)(3) of this subpart, the owner 
or operator shall monitor the following information for all heats 
covered by the test:
    (1) Charge weights and materials, and tap weights and materials;
    (2) Heat times, including start and stop times, and a log of process 
operation, including periods of no operation during testing and the 
pressure inside the furnace where direct-shell evacuation systems are 
used;
    (3) Control device operation log; and
    (4) Continuous opacity monitor or Method 9 data.

Sec. 60.275  Test methods and procedures.

    (a) During performance tests required in Sec. 60.8, the owner or 
operator shall not add gaseous diluent to the effluent gas after the 
fabric in any pressurized fabric collector, unless the amount of 
dilution is separately determined and considered in the determination of 
emissions.
    (b) When emissions from any EAF(s) are combined with emissions from 
facilities not subject to the provisions of this subpart but controlled

    (e) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.272 as follows:
    (1) Method 5 shall be used for negative-pressure fabric filters and 
other types of control devices and Method 5D shall be used for positive-
pressure fabric filters to determine the particular matter concentration 
and, if applicable, the volumetric flow rate of the effluent gas. The 
sampling time and sample volume for each run shall be at least 4 hours 
and 4.5 dscm (160 dscf) and, when a single EAF is sampled, the sampling 
time shall include an integral number of heats.
    (2) When more than one control device serves the EAF(s) being 
tested, the concentration of particulate matter shall be determined 
using the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.013

where:

cst = average concentration of particulate matter, mg/dscm 
          (gr/dscf).
csi = concentration of particulate matter from control device 
          ``i'', mg/dscm (gr/dscf).
n = total number of control devices tested.
Qsdi = volumetric flow rate of stack gas from control device 
          ``i'', dscm/hr (dscf/hr).

    (3) Method 9 and the procedures of Sec. 60.11 shall be used to

[[Page 493]]

    (4) To demonstrate compliance with Sec. 60.272(a) (1), (2), and 
(3), the Method 9 test runs shall be conducted concurrently with the 
particulate matter test runs, unless inclement weather interferes.
    (f) To comply with Sec. 60.274 (c), (f), (g), and (i), the owner or 
operator shall obtain the information in these paragraphs during the

    (g) Where emissions from any EAF(s) are combined with emissions from 
facilities not subject to the provisions of this subpart but controlled 
by a common capture system and control device, the owner or operator may 
use any of the following procedures during a performance test:
    (1) Base compliance on control of the combined emissions.
    (2) Utilize a method acceptable to the Administrator which 
compensates for the emissions from the facilities not subject to the 
provisions of this subpart.
    (3) Any combination of the criteria of paragraphs (g)(1) and (g)(2) 
of this section.
    (h) Where emissions from any EAF(s) are combined with emissions from

continuous opacity monitoring system, as allowed for by Sec. 60.273(c), 
visible emission observations shall be conducted at least once per day 
for at least three 6-minute periods when the furnace is operating in the 
melting and refining period. All visible emissions observations shall be 
conducted in accordance with Method 9. If visible emissions occur from 
more than one point, the opacity shall be recorded for any points where 
visible emissions are observed. Where it is possible to determine that a 
number of visible emission sites relate to only one incident of the 
visible emission, only one set of three 6-minute observations will be 
required. In that case, the Method 9 observations must be made for the 
site of highest opacity that directly relates to the cause (or location) 
of visible emissions observed during a single incident. Records shall be 
maintained of any 6-minute average that is in excess of the emission 
limit specified in Sec. 60.272(a).
    (j) Unless the presence of inclement weather makes concurrent 
testing infeasible, the owner or operator shall conduct concurrently the 
performance tests required under Sec. 60.8 to demonstrate compliance 
with Sec. 60.272(a) (1), (2), and (3) of this subpart.

Sec. 60.272a  Standard for particulate matter.

    (a) On and after the date of which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere from an EAF or an AOD vessel any gases which:
    (1) Exit from a control device and contain particulate matter in 
excess of 12 mg/dscm (0.0052 gr/dscf);
    (2) Exit from a control device and exhibit 3 percent opacity or 
greater; and
    (3) Exit from a shop and, due solely to the operations of any 
affected EAF(s) or AOD vessel(s), exhibit 6 percent opacity or greater.
    (b) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere from the dust-handling system any gases that exhibit 10 
percent opacity or greater.



Sec. 60.273a  Emission monitoring.

    (a) Except as provided under paragraphs (b) and (c) of this section, 
a continuous monitoring system for the measurement of the opacity of 
emissions discharged into the atmosphere from the control device(s) 
shall be installed, calibrated, maintained, and operated by the owner or 
operator subject to the provisions of this subpart.
    (b) No continuous monitoring system shall be required on any control 
device serving the dust-handling system.
    (c) A continuous monitoring system for the measurement of the 
opacity of emissions discharged into the atmosphere from the control 
device(s) is not required on any modular, multi-stack, negative-pressure 
or positive-pressure fabric filter if observations of the opacity of the 
visible emissions from the control device are performed by a certified 
visible emission observer; or on any single-stack fabric filter if 
visible emissions from the control device are performed by a certified 
visible emission observer and the owner installs and continuously 
operates a bag leak detection system according to paragraph (e) of this 
section. Visible emission observations shall be conducted at least once 
per day for at least three 6-minute periods when the furnace is 
operating in the melting and refining period. All visible emissions 
observations shall be conducted in accordance with Method 9. If visible 
emissions occur from more than one point, the opacity shall be recorded 
for any points where visible emissions are observed. Where it is 
possible to determine that a number of visible emission sites relate to 
only one incident of the visible emission, only one set of three 6-
minute observations will be required. In that case, the Method 9 
observations must be made for the site of highest opacity that directly 
relates to the cause (or location) of visible emissions observed during 
a single incident. Records shall be maintained of any 6-minute average 
that is in excess of the emission limit specified in Sec. 60.272a(a).
    (d) A furnace static pressure monitoring device is not required on 
any EAF equipped with a DEC system if observations of shop opacity are 
performed by a certified visible emission observer as follows: Shop 
opacity observations shall be conducted at least once per day when the 
furnace is operating in the meltdown and refining period. Shop opacity 
shall be determined as the arithmetic average of 24 consecutive 15-
second opacity observations of emissions from the shop taken in 
accordance with Method 9. Shop opacity shall be recorded for any 
point(s) where visible emissions are observed. Where it is possible to 
determine that a number of visible emission sites relate to only one 
incident of visible emissions, only one observation of shop opacity will 
be required. In this case, the shop opacity observations must be made 
for the site of highest opacity that directly relates to the cause (or 
location) of visible emissions observed during a single incident.
    (e) A bag leak detection system must be installed and continuously 
operated on all single-stack fabric filters if the owner or operator 
elects not to install and operate a continuous opacity monitoring system 
as provided for under paragraph (c) of this section. In addition, the 
owner or operator shall meet the visible emissions observation 
requirements in paragraph (c) of this section. The bag leak detection 
system

[[Page 497]]

must meet the specifications and requirements of paragraphs (e)(1) 
through (8) of this section.
    (1) The bag leak detection system must be certified by the 
manufacturer to be capable of detecting particulate matter emissions at 
concentrations of 1 milligram per actual cubic meter (0.00044 grains per 
actual cubic foot) or less.
    (2) The bag leak detection system sensor must provide output of 
relative particulate matter loadings and the owner or operator shall 
continuously record the output from the bag leak detection system using 
electronic or other means (e.g., using a strip chart recorder or a data 
logger.)
    (3) The bag leak detection system must be equipped with an alarm 
system that will sound when an increase in relative particulate loading 
is detected over the alarm set point established according to paragraph 
(e)(4) of this section, and the alarm must be located such that it can 
be heard by the appropriate plant personnel.
    (4) For each bag leak detection system required by paragraph (e) of 
this section, the owner or operator shall develop and submit to the 
Administrator or delegated authority, for approval, a site-specific 
monitoring plan that addresses the items identified in paragraphs (i) 
through (v) of this paragraph (e)(4). For each bag leak detection system 
that operates based on the triboelectric effect, the monitoring plan 
shall be consistent with the recommendations contained in the U.S. 
Environmental Protection Agency guidance document ``Fabric Filter Bag 
Leak Detection Guidance'' (EPA-454/R-98-015). The owner or operator 
shall operate and maintain the bag leak detection system according to 
the site-specific monitoring plan at all times. The plan shall describe 
the following:
    (i) Installation of the bag leak detection system;
    (ii) Initial and periodic adjustment of the bag leak detection 
system including how the alarm set-point will be established;
    (iii) Operation of the bag leak detection system including quality 
assurance procedures;
    (iv) How the bag leak detection system will be maintained including 
a routine maintenance schedule and spare parts inventory list; and
    (v) How the bag leak detection system output shall be recorded and 
stored.
    (5) The initial adjustment of the system shall, at a minimum, 
consist of establishing the baseline output by adjusting the sensitivity 
(range) and the averaging period of the device, and establishing the 
alarm set points and the alarm delay time (if applicable).
    (6) Following initial adjustment, the owner or operator shall not 
adjust the averaging period, alarm set point, or alarm delay time 
without approval from the Administrator or delegated authority except as 
provided for in paragraphs (e)(6)(i) and (ii) of this section.
    (i) Once per quarter, the owner or operator may adjust the 
sensitivity of the bag leak detection system to account for seasonal 
effects including temperature and humidity according to the procedures 
identified in the site-specific monitoring plan required under 
paragraphs (e)(4) of this section.
    (ii) If opacities greater than zero percent are observed over four 
consecutive 15-second observations during the daily opacity observations 
required under paragraph (c) of this section and the alarm on the bag 
leak detection system does not sound, the owner or operator shall lower 
the alarm set point on the bag leak detection system to a point where 
the alarm would have sounded during the period when the opacity 
observations were made.
    (7) For negative pressure, induced air baghouses, and positive 
pressure baghouses that are discharged to the atmosphere through a 
stack, the bag leak detection sensor must be installed downstream of the 
baghouse and upstream of any wet scrubber.
    (8) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (f) For each bag leak detection system installed according to 
paragraph (e) of this section, the owner or operator shall initiate 
procedures to determine the cause of all alarms within 1 hour of an 
alarm. Except as provided for under paragraph (g) of this section,

[[Page 498]]

the cause of the alarm must be alleviated within 3 hours of the time the 
alarm occurred by taking whatever corrective action(s) are necessary. 
Corrective actions may include, but are not limited to, the following:
    (1) Inspecting the baghouse for air leaks, torn or broken bags or 
filter media, or any other condition that may cause an increase in 
particulate emissions;
    (2) Sealing off defective bags or filter media;
    (3) Replacing defective bags or filter media or otherwise repairing 
the control device;
    (4) Sealing off a defective baghouse compartment;
    (5) Cleaning the bag leak detection system probe or otherwise 
repairing the bag leak detection system; and
    (6) Shutting down the process producing the particulate emissions.
    (g) In approving the site-specific monitoring plan required in 
paragraph (e)(4) of this section, the Administrator or delegated 
authority may allow owners or operators more than 3 hours to alleviate 
specific conditions that cause an alarm if the owner or operator 
identifies the condition that could lead to an alarm in the monitoring 
plan, adequately explains why it is not feasible to alleviate the 
condition within 3 hours of the time the alarm occurred, and 
demonstrates that the requested additional time will ensure alleviation 
of the condition as expeditiously as practicable.

Sec. 60.274a  Monitoring of operations.

    (a) The owner or operator subject to the provisions of this subpart 
shall maintain records of the following information:
    (1) All data obtained under paragraph (b) of this section; and
    (2) All monthly operational status inspections performed under 
paragraph (c) of this section.
    (b) Except as provided under paragraph (e) of this section, the 
owner or operator subject to the provisions of this subpart shall check 
and record on a once-per-shift basis the furnace static pressure (if DEC 
system is in use, and a furnace static pressure gauge is installed 
according to paragraph (f) of this section) and either: check and record 
the control system fan motor amperes and damper position on a once-per-
shift basis; install, calibrate, and maintain a monitoring device that 
continuously records the volumetric flow rate through each separately 
ducted hood; or install, calibrate, and maintain a monitoring device 
that continuously records the volumetric flow rate at the control device 
inlet and check and record damper positions on a once-per-shift basis. 
The monitoring device(s) may be installed in any appropriate location in 
the exhaust duct such that reproducible flow rate monitoring will 
result. The flow rate monitoring device(s) shall have an accuracy of 
10 percent over its normal operating range and 
shall be calibrated according to the manufacturer's instructions. The 
Administrator may require the owner or operator to demonstrate the 
accuracy of the monitoring device(s) relative to Methods 1 and 2 of 
appendix A of this part.
    (c) When the owner or operator of an affected facility is required 
to demonstrate compliance with the standards under Sec. 60.272a(a)(3) 
and at any other time that the Administrator may require (under section 
114 of the CAA, as amended) either: the control system fan motor amperes 
and all damper positions, the volumetric flow rate through each 
separately ducted hood, or the volumetric flow rate at the control 
device inlet and all damper positions shall be determined during all 
periods in which a hood is operated for the purpose of capturing 
emissions from the affected facility subject to paragraph (b) of this 
section. The owner or operator may petition the Administrator for 
reestablishment of these parameters whenever the owner or operator can 
demonstrate to the Administrator's satisfaction that the affected 
facility operating conditions upon which the parameters were previously 
established are no longer applicable. The values of these parameters as 
determined during the most recent demonstration of compliance shall be 
maintained at the appropriate level for each applicable period. 
Operation at

[[Page 499]]

other than baseline values may be subject to the requirements of Sec. 
60.276a(c).
    (d) Except as provided under paragraph (e) of this section, the 
owner or operator shall perform monthly operational status inspections 
of the equipment that is important to the performance of the total 
capture system (i.e., pressure sensors, dampers, and damper switches). 
This inspection shall include observations of the physical appearance of 
the equipment (e.g., presence of holes in ductwork or hoods, flow 
constrictions caused by dents or accumulated dust in ductwork, and fan 
erosion). Any deficiencies shall be noted and proper maintenance 
performed.
    (e) The owner or operator may petition the Administrator to approve 
any alternative to either the monitoring requirements specified in 
paragraph (b) of this section or the monthly operational status 
inspections specified in paragraph (d) of this section if the 
alternative will provide a continuous record of operation of each 
emission capture system.
    (f) Except as provided for under Sec. 60.273a(d), if emissions 
during any phase of the heat time are controlled by the use of a DEC 
system, the owner or operator shall install, calibrate, and maintain a 
monitoring device that allows the pressure in the free space inside the 
EAF to be monitored. The pressure shall be recorded as 15-minute 
integrated averages. The monitoring device may be installed in any 
appropriate location in the EAF or DEC duct prior to the introduction of 
ambient air such that reproducible results will be obtained. The 
pressure monitoring device shall have an accuracy of 5 mm of water gauge over its normal operating range and 
shall be calibrated according to the manufacturer's instructions.
    (g) Except as provided for under Sec. 60.273a(d), when the owner or 
operator of an EAF controlled by a DEC is required to demonstrate 
compliance with the standard under Sec. 60.272a(a)(3), and at any other 
time the Administrator may require (under section 114 of the Clean Air 
Act, as amended), the pressure in the free space inside the furnace 
shall be determined during the meltdown and refining period(s) using the 
monitoring device required under paragraph (f) of this section. The 
owner or operator may petition the Administrator for reestablishment of 
the pressure whenever the owner or operator can demonstrate to the 
Administrator's satisfaction that the EAF operating conditions upon 
which the pressures were previously established are no longer 
applicable. The pressure determined during the most recent demonstration 
of compliance shall be maintained at all times when the EAF is operating 
in a meltdown and refining period. Operation at higher pressures may be 
considered by the Administrator to be unacceptable operation and

Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/
          hr).
BLS = black liquor solids (dry weight) feed rate, kg/hr (ton/hr).

    (2) Method 5 shall be used to determine the particulate matter 
concentration (cs) and the volumetric flow rate 
(Qsd) of the effluent gas. The sampling time and sample 
volume shall be at least 60 minutes and 0.90 dscm (31.8 dscf). Water

TRS concentration shall be corrected to the appropriate oxygen 
concentration using the procedure in Sec. 60.284(c)(3). The sampling 
time shall be at least 3 hours, but no longer than 6 hours.
    (2) The emission rate correction factor, integrated sampling and 
analysis procedure of Method 3B shall be used to determine the oxygen 
concentration. The sample shall be taken over the same time period as 
the TRS samples.
    (3) When determining whether a furnace is a straight kraft recovery 
furnace or a cross recovery furnace, TAPPI Method T.624 (incorporated by 
reference--see Sec. 60.17) shall be used to determine sodium sulfide, 
sodium hydroxide, and sodium carbonate. These determinations shall be 
made 3 times daily from the green liquor, and the daily average values 
shall be converted to sodium oxide (Na20) and substituted 
into the following equation to determine the green liquor sulfidity:

rate or the pulp production rate (P).
    (f) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) For Method 5, Method 17 may be used if a constant value of 0.009 
g/dscm (0.004 gr/dscf) is added to the results of Method 17 and the

of this section.
    (1) For any incinerator, a monitoring device for the continuous 
measurement of the combustion temperature at the point of incineration 
of effluent gases which are emitted from any digester system, brown 
stock washer system, multiple effect evaporator system, or condensate 
stripper system where the provisions of Sec. 60.283a(a)(1)(iii) apply. 
The monitoring device is to be certified by the manufacturer to be 
accurate within 1 percent of the temperature being

dissolving tank dynamic scrubbers that operate at ambient pressure or 
for low-energy entrainment scrubbers where the fan speed does not vary.
    (iv) As an alternative to scrubbing liquid flow rate measurement 
under paragraph (b)(2)(ii) of this section, a monitoring device for 
measurement of scrubbing liquid supply pressure may be used. The 
monitoring device is to be certified by the manufacturer to be accurate 
within 15 percent of design scrubbing liquid 
supply pressure. The pressure sensor or tap is to be located close to

the secondary voltage and secondary current measurements.
    (4) For any recovery furnace or lime kiln using an ESP followed by a 
wet scrubber, the owner or operator must use the continuous parameter 
monitoring devices specified in paragraphs (b)(2) and (3) of this 
section. The opacity monitoring system specified in paragraph (a)(1) of 
this section is not required for combination ESP/wet scrubber control 
device systems.
    (c) Monitor operation and calculations. Any owner or operator 
subject to the provisions of this subpart must follow the procedures for 
collecting and reducing monitoring data and setting operating limits in 
paragraphs (c)(1) through (6) of this section. Subpart A of this part 
specifies methods for reducing continuous opacity monitoring system 
data.
    (1) Any owner or operator subject to the provisions of this subpart 
must, except where the provisions of Sec. 60.283a(a)(1)(iii) or (iv) 
apply, perform the following:
    (i) Calculate and record on a daily basis 12-hour average TRS 
concentrations for the two consecutive periods of each operating day. 
Each 12-hour average must be determined as the arithmetic mean of the 
appropriate 12 contiguous 1-hour average TRS concentrations provided by 
each continuous monitoring system installed under paragraph (a)(2) of 
this section.
    (ii) Calculate and record on a daily basis 12-hour average oxygen 
concentrations for the two consecutive periods of each operating day for 
the recovery furnace and lime kiln. These 12- hour averages must 
correspond to the 12-hour average TRS concentrations under paragraph 
(c)(1)(i) of this section and must be determined as an arithmetic mean 
of the appropriate 12 contiguous 1-hour average oxygen concentrations 
provided by each continuous monitoring system installed under paragraph 
(a)(2) of this section.
    (iii) Using the following equation, correct all 12-hour average TRS 
concentrations to 10 volume percent oxygen, except that all 12-hour 
average TRS concentrations from a recovery furnace must be corrected to 
8 volume percent oxygen instead of 10 percent, and all 12-hour average 
TRS concentrations from a facility to which the provisions of Sec. 
60.283a(a)(1)(v) apply must not be corrected for oxygen content:

Ccorr = Cmeas x (21-X/21-Y)


[[Page 512]]


Where:

Ccorr = the concentration corrected for oxygen.
Cmeas = the 12-hour average of the measured concentrations 
          uncorrected for oxygen.
X = the volumetric oxygen concentration in percentage to be corrected to 
          (8 percent for recovery furnaces and 10 percent for lime 
          kilns, incinerators, or other devices).
Y = the 12-hour average of the measured volumetric oxygen concentration.

    (2) Record at least once each successive 5-minute period all 
measurements obtained from the continuous monitoring devices installed 
under paragraph (b)(1) of this section. Calculate 3-hour block averages 
from the recorded measurements of incinerator temperature. Temperature 
measurements recorded when no TRS emissions are fired in the incinerator 
(e.g., during incinerator warm-up and cool-down periods when no TRS 
emissions are generated or an alternative control device is used) may be 
omitted from the block average calculation.
    (3) Record at least once each successive 15-minute period all 
measurements obtained from the continuous monitoring devices installed 
under paragraph (b)(2) through (4) of this section and reduce the data 
as follows:
    (i) Calculate 12-hour block averages from the recorded measurements 
of wet scrubber pressure drop (or smelt dissolving tank scrubber fan 
amperage or RPM) and liquid flow rate (or liquid supply pressure), as 
applicable.
    (ii) Calculate semiannual averages from the recorded measurements of 
ESP parameters (secondary voltage and secondary current, or total 
secondary power) for ESP-controlled recovery furnaces or lime kilns that 
measure opacity in addition to ESP parameters.
    (iii) Calculate 12-hour block averages from the recorded 
measurements of ESP parameters (secondary voltage and secondary current, 
or total secondary power) for recovery furnaces or lime kilns with 
combination ESP/wet scrubber controls.
    (4) During the initial performance test required in Sec. 60.285a, 
the owner or operator must establish site-specific operating limits for 
the monitoring parameters in paragraphs (b)(2) through (4) of this 
section by continuously monitoring the parameters and determining the 
arithmetic average value of each parameter during the performance test. 
The arithmetic average of the measured values for the three test runs 
establishes your minimum site-specific operating limit for each wet 
scrubber or ESP parameter (except for smelt dissolving tank scrubber fan 
amperage or RPM). For smelt dissolving tank scrubber fan amperage, set 
the minimum operating limit using one of the methods in paragraphs 
(c)(4)(i) or (ii) of this section. For smelt dissolving tank scrubber 
RPM, the minimum RPM must be set as specified in paragraph (c)(4)(iii) 
of this section. Multiple performance tests may be conducted to 
establish a range of parameter values. The owner or operator may 
establish replacement operating limits for the monitoring parameters 
during subsequent performance tests using the test methods in Sec. 
60.285a.
    (i) The minimum fan amperage operating limit must be set as the 
midpoint between the lowest of the 1-hour average fan amperage values 
associated with each test run demonstrating compliance with the 
applicable emission limit in Sec. 60.282a and the no-load amperage 
value. The no-load amperage value must be determined using manufacturers 
specifications, or by performing a no-load test of the fan motor for 
each smelt dissolving tank scrubber; or
    (ii) The minimum percent full load amperage (PFLA) to the fan motor 
must be set as the percent of full load amperage under no-load, plus 10 
percent. The PFLA is calculated by dividing the no-load amperage value 
by the highest of the 1-hour average fan amperage values associated with 
each test run demonstrating compliance with the applicable emission 
limit in Sec. 60.282a multiplied by 100 and then adding 10 percent. The 
no-load amperage value must be determined using manufacturers 
specifications, or by performing a no-load test of the fan motor for 
each smelt dissolving tank scrubber.
    (iii) The minimum RPM must be set as 5 percent lower than the lowest 
1-hour average RPM associated with

[[Page 513]]

each test run demonstrating compliance with the applicable emission 
limit.
    (5) You must operate the continuous monitoring systems required in 
paragraphs (a) and (b) of this section to collect data at all required 
intervals at all times the affected facility is operating except for 
periods of monitoring system malfunctions or out-of-control periods, 
repairs associated with monitoring system malfunctions or out-of-control 
periods, and required monitoring system quality assurance or quality 
control activities including, as applicable, calibration checks and 
required zero and span adjustments.
    (6) You may not use data recorded during monitoring system 
malfunctions or out-of-control periods, repairs associated with 
monitoring system malfunctions or out-of-control periods, or required 
monitoring system quality assurance or control activities in 
calculations used to report emissions or operating limits. You must use 
all the data collected during all other periods in assessing the 
operation of the control device and associated control system.
    (7) Except for periods of monitoring system malfunctions, repairs 
associated with monitoring system malfunctions, and required quality 
monitoring system quality assurance or quality control activities 
(including, as applicable, system accuracy audits and required zero and 
span adjustments), failure to collect required data is a deviation of

be considered when determining compliance with the excess emission 
provisions in paragraphs (e)(1)(i) and (iii) of this section during 
periods of startup or shutdown when the 12-hour average stack oxygen 
percentage approaches ambient conditions. If the 12-hour average TRS 
concentration uncorrected for oxygen is less than the applicable limit 
(5 ppm for recovery furnaces or 8 ppm for lime kilns) during periods of 
startup or shutdown when the 12-hour average stack oxygen concentration 
is 15 percent or greater, then the Administrator will consider the TRS

and procedures in this section, except as provided in Sec. 60.8(b). 
Acceptable alternative methods and procedures are given in paragraph (f) 
of this section. Section 60.8(c) must be read as follows for purposes of 
this subpart: Performance tests shall be conducted under such conditions 
as the Administrator shall specify to the plant operator based on 
representative performance of the affected facility. The owner or 
operator shall make available to the Administrator such records as may 
be necessary to determine the conditions of the performance tests. 
Operations during periods of startup, shutdown and malfunction shall not 
constitute representative conditions for the purpose of a performance 
test.
    (b) The owner or operator must determine compliance with the 
filterable particulate matter standards in Sec. 60.282a(a)(1), (2), (5) 
and (6) as follows:
    (1) Method 5 of appendix A-3 of this part must be used to determine 
the filterable particulate matter concentration. The sampling time and 
sample volume for each run must be at least 60 minutes and 0.90 dscm 
(31.8 dscf). Water must be used as the cleanup solvent instead of 
acetone in the sample recovery procedure. The particulate concentration 
must be corrected to the appropriate oxygen concentration according to 
Sec. 60.284a(c)(1)(iii).
    (2) The emission rate correction factor, integrated sampling and 
analysis procedure of Method 3B of appendix A-2 of this part must be 
used to determine the oxygen concentration. The gas sample must be taken 
at the same time and at the same traverse points as the particulate 
sample.
    (3) Method 9 of appendix A-4 of this part and the procedures in 
Sec. 60.11 must be used to determine opacity. Opacity measurement is 
not required for recovery furnaces or lime kilns operating with a wet 
scrubber alone or a wet scrubber in combination with an ESP.
    (4) In addition to the initial performance test required by this 
subpart and Sec. 60.8(a), you must conduct repeat performance tests for 
filterable particulate matter at intervals no longer than 5 years 
following the previous performance test using the procedures in 
paragraphs (b)(1) and (2) of this section.
    (5) When the initial and repeat performance tests are conducted for 
filterable particulate matter, the owner or operator must also measure 
condensable particulate matter using Method 202 of appendix M of 40 CFR 
part 51.
    (c) The owner or operator must determine compliance with the 
filterable particular matter standards in Sec. 60.282a(a)(3) and (4) as 
follows:
    (1) The emission rate (E) of filterable particulate matter must be 
computed for each run using the following equation:

E = csQsd/BLS

Where:

E = emission rate of filterable particulate matter, g/kg (lb/ton) of 
          BLS.
cs = Concentration of filterable particulate matter, g/dscm 
          (lb/dscf).
Qsd = volumetric flow rate of effluent gas, dry standard 
          cubic meter per hour (dscm/hr) (dry standard cubic feet per 
          hour (dscf/hr)).
BLS = black liquor solids (dry weight) feed rate, kg/hr (ton/hr).

    (2) Method 5 of appendix A-3 of this part must be used to determine 
the filterable particulate matter concentration (cs) and the 
volumetric flow rate (Qsd) of the effluent gas. The sampling 
time and sample volume must be at least 60 minutes and 0.90 dscm (31.8 
dscf). Water must be used instead of acetone in the sample recovery.
    (3) Process data must be used to determine the black liquor solids 
(BLS) feed rate on a dry weight basis.
    (4) In addition to the initial performance test required by this 
subpart and Sec. 60.8(a), you must conduct repeat performance tests for 
filterable particulate matter at intervals no longer than 5 years 
following the previous performance test using the procedures in 
paragraphs (c)(1) through (3) of this section.
    (5) When the initial and repeat performance tests are conducted for 
filterable particulate matter, the owner or

[[Page 516]]

operator must also measure condensable particulate matter using Method 
202 of appendix M of 40 CFR part 51.
    (d) The owner or operator must determine compliance with the TRS 
standards in Sec. 60.283a, except Sec. 60.283a(a)(1)(vi) and (4), as 
follows:
    (1) Method 16 of appendix A-6 of this part must be used to determine 
the TRS concentration. The TRS concentration must be corrected to the 
appropriate oxygen concentration using the procedure in Sec. 
60.284a(c)(1)(iii). The sampling time must be at least 3 hours, but no 
longer than 6 hours.
    (2) The emission rate correction factor, integrated sampling and 
analysis procedure of Method 3B of appendix A-2 of this part must be 
used to determine the oxygen concentration. The sample must be taken 
over the same time period as the TRS samples.
    (3) When determining whether a furnace is a straight kraft recovery 
furnace or a cross recovery furnace, TAPPI Method T 624 (incorporated by 
reference--see Sec. 60.17) must be used to determine sodium sulfide, 
sodium hydroxide, and sodium carbonate. These determinations must be 
made 3 times daily from the green liquor, and the daily average values 
must be converted to sodium oxide (Na20) and substituted into 
the following equation to determine the green liquor sulfidity:

GLS = 100CNa2S / 
(CNa2SCNaOH 
CNa2CO3)

Where:

GLS = green liquor sulfidity, percent.
CNa2S = concentration of Na2S as 
          Na2O, milligrams per liter (mg/L) (grains per 
          gallon (gr/gal)).
CNaOH = concentration of NaOH as Na2O, mg/L (gr/
          gal).
CNa2CO3 = concentration of 
          Na2CO3 as Na2O, mg/L (gr/
          gal).

    (4) For recovery furnaces and lime kilns, in addition to the initial 
performance test required in this subpart and Sec. 60.8(a), you must 
conduct repeat TRS performance tests at intervals no longer than 5 years 
following the previous performance test using the procedures in 
paragraphs (d)(1) and (2) of this section.
    (e) The owner or operator must determine compliance with the TRS 
standards in Sec. 60.283a(a)(1)(vi) and (4) as follows:
    (1) The emission rate (E) of TRS must be computed for each run using 
the following equation:

E = CTRS F Qsd/P

Where:

E = emission rate of TRS, g/kg (lb/ton) of BLS or ADP.
CTRS = average combined concentration of TRS, ppm.
F = conversion factor, 0.001417 g H2S/cubic meter (m\3\)-ppm 
          (8.846 x 10\-8\ lb H2S/cubic foot (ft\3\)-ppm).
Qsd = volumetric flow rate of stack gas, dscm/hr (dscf/hr).
P = black liquor solids feed or pulp production rate, kg/hr (ton/hr).

    (2) Method 16 of appendix A-6 of this part must be used to determine 
the TRS concentration (CTRS).
    (3) Method 2 of appendix A-1 of this part must be used to determine 
the volumetric flow rate (Qsd) of the effluent gas.
    (4) Process data must be used to determine the black liquor feed 
rate or the pulp production rate (P).
    (5) For smelt dissolving tanks, in addition to the initial 
performance test required in this subpart and Sec. 60.8(a), you must 
conduct repeat TRS performance tests at intervals no longer than 5 years 
following the previous performance test using the procedures in 
paragraphs (e)(1) through (4) of this section.
    (f) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) In place of Method 5 of appendix A-3 of this part, Method 17 of 
appendix A-6 of this part may be used if a constant value of 0.009 g/
dscm (0.004 gr/dscf) is added to the results of Method 17 and the stack 
temperature is no greater than 204 [deg]C (400 [deg]F).
    (2) In place of Method 16 of appendix A-6 of this part, Method 16A, 
16B, or 16C of appendix A-6 of this part may be used.
    (3) In place of Method 3B of appendix A-2 of this part, ASME PTC 
19.10-1981 (incorporated by reference--see Sec. 60.17) may be used.

Sec. 60.286a  Affirmative defense for violations of emission
standards during malfunction.

    In response to an action to enforce the standards set forth in 
Sec. Sec. 60.282a and 60.283a, you may assert an affirmative defense to 
a claim for civil penalties for violations of such standards that are 
caused by malfunction, as defined at Sec. 60.2. Appropriate penalties 
may be assessed if you fail to meet your burden of proving all of the 
requirements in the affirmative defense. The affirmative defense must 
not be available for claims for injunctive relief.
    (a) Assertion of affirmative defense. To establish the affirmative 
defense in any action to enforce such a standard, you must timely meet 
the reporting requirements in paragraph (b) of this section, and must 
prove by a preponderance of evidence that:
    (1) The violation:
    (i) Was caused by a sudden, infrequent, and unavoidable failure of 
air pollution control equipment, process equipment, or a process to 
operate in a normal or usual manner; and
    (ii) Could not have been prevented through careful planning, proper 
design or better operation and maintenance practices; and
    (iii) Did not stem from any activity or event that could have been 
foreseen and avoided, or planned for; and
    (iv) Was not part of a recurring pattern indicative of inadequate 
design, operation, or maintenance; and
    (2) Repairs were made as expeditiously as possible when a violation 
occurred; and
    (3) The frequency, amount, and duration of the violation (including 
any bypass) were minimized to the maximum extent practicable; and
    (4) If the violation resulted from a bypass of control equipment or 
a process, then the bypass was unavoidable to prevent loss of life, 
personal injury, or severe property damage; and
    (5) All possible steps were taken to minimize the impact of the 
violation on ambient air quality, the environment, and human health; and
    (6) All emission monitoring and control systems were kept in 
operation if at all possible, consistent with safety and good air 
pollution control practices; and
    (7) All of the actions in response to the violation were documented 
by properly signed, contemporaneous operating logs; and
    (8) At all times, the affected source was operated in a manner 
consistent with good practices for minimizing emissions; and
    (9) A written root cause analysis has been prepared, the purpose of 
which is to determine, correct, and eliminate the primary causes of the 
malfunction and the violation resulting from the malfunction event at 
issue. The analysis must also specify, using best monitoring methods and 
engineering judgment, the amount of any emissions that were the result 
of the malfunction.
    (b) Report. The owner or operator seeking to assert an affirmative 
defense must submit a written report to the Administrator with all 
necessary supporting documentation that explains how it has met the 
requirements set forth in paragraph (a) of this section. This 
affirmative defense report must be included in the first periodic 
compliance, deviation report or excess emission report otherwise 
required after the initial occurrence of the violation of the relevant 
standard (which may be the end of any applicable averaging period). If 
such compliance, deviation report or excess emission report is due less 
than 45 days after the initial occurrence of the violation, the 
affirmative defense report may be included in the second compliance, 
deviation report or excess emission report due after the initial 
occurrence of the violation of the relevant standard.

Sec. 60.288a  Reporting.

    (a) For the purpose of reports required under Sec. 60.7(c), any 
owner or operator subject to the provisions of this subpart must report 
semiannually periods of excess emissions defined in Sec. 60.284a(d).
    (b) Within 60 days after the date of completing each performance 
test (defined in Sec. 60.8) as required by this subpart you must submit 
the results of the performance tests, including any associated fuel 
analyses, required by this subpart to the EPA as follows. You must use 
the latest version of the EPA's Electronic Reporting Tool (ERT) (see 
http://www.epa.gov/ttn/chief /ert/index.html) existing at the time of 
the performance test to generate a submission package file, which 
documents performance test data. You must then submit the file generated 
by the ERT through the EPA's Compliance and Emissions Data Reporting 
Interface (CEDRI), which can be accessed by logging in to the EPA's 
Central Data Exchange (CDX) (https://cdx.epa.gov/). Only data collected 
using test methods supported by the ERT as listed on the ERT Web site 
are subject to the requirement to submit the performance test data 
electronically. Owners or operators who claim that some of the 
information being submitted for performance tests is confidential 
business information (CBI) must submit a complete ERT file including 
information claimed to be CBI on a compact disk, flash drive, or other 
commonly used electronic storage media to the EPA. The electronic media 
must be clearly marked as CBI and mailed to U.S. EPA/OAPQS/CORE CBI 
Office, Attention: WebFIRE Administrator, MD C404-02, 4930 Old Page Rd., 
Durham, NC 27703.

[[Page 519]]

The same ERT file with the CBI omitted must be submitted to the EPA via 
CDX as described earlier in this paragraph (b). At the discretion of the 
delegated authority, you must also submit these reports, including the 
CBI, to the delegated authority in the format specified by the delegated 
authority. For any performance test conducted using test methods that 
are not listed on the ERT Web site, the owner or operator must submit 
the results of the performance test to the Administrator at the 
appropriate address listed in Sec. 60.4.
    (c) Within 60 days after the date of completing each CEMS 
performance evaluation test as defined in Sec. 60.13, you must submit 
relative accuracy test audit (RATA) data to the EPA's Central Data 
Exchange (CDX) by using CEDRI in accordance with paragraph (b) of this 
section. Only RATA pollutants that can be documented with the ERT (as 
listed on the ERT Web site) are subject to this requirement. For any 
performance evaluations with no corresponding RATA pollutants listed on 
the ERT Web site, the owner or operator must submit the results of the 
performance evaluation to the Administrator at the appropriate address 
listed in Sec. 60.4.
    (d) If a malfunction occurred during the reporting period, you must 
submit a report that contains the following:
    (1) The number, duration, and a brief description for each type of 
malfunction which occurred during the reporting period and which caused 
or may have caused any applicable emission limitation to be exceeded.

Sec. 60.291  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A of this part, unless 
otherwise required by the context.
    All-electric melter means a glass melting furnace in which all the 
heat required for melting is provided by electric current from 
electrodes submerged in the molten glass, although some fossil fuel may 
be charged to the furnace as raw material only.
    Borosilicate recipe means glass product composition of the following 
approximate ranges of weight proportions: 60 to 80 percent silicon 
dioxide, 4 to 10 percent total R2O (e.g., Na2O and 
K2O), 5 to 35 percent boric oxides, and 0 to 13 percent other 
oxides.
    Container glass means glass made of soda-lime recipe, clear or 
colored, which is pressed and/or blown into bottles, jars, ampoules, and 
other products listed in Standard Industrial Classification 3221 (SIC 
3221).
    Experimental furnace means a glass melting furnace with the sole 
purpose of operating to evaluate glass melting processes, technologies,

is sold (except for further research and development purposes) or that 
is used as a raw material for nonexperimental furnaces.
    Flat glass means glass made of soda-lime recipe and produced into 
continuous flat sheets and other products listed in SIC 3211.
    Flow channels means appendages used for conditioning and 
distributing molten glass to forming apparatuses and are a permanently

with emissions from the melter cooling system prior to their being 
vented to the atmosphere.

[[Page 520]]

    Glass melting furnace means a unit comprising a refractory vessel in 
which raw materials are charged, melted at high temperature, refined, 
and conditioned to produce molten glass. The unit includes foundations, 
superstructure and retaining walls, raw material charger systems, heat 
exchangers, melter cooling system, exhaust system, refractory brick 
work, fuel supply and electrical boosting equipment, integral control 
systems and instrumentation, and appendages for conditioning and 
distributing molten glass to forming apparatuses. The forming 
apparatuses, including the float bath used in flat glass manufacturing 
and flow channels in wool fiberglass and textile fiberglass 
manufacturing, are not considered part of the glass melting furnace.
    Glass produced means the weight of the glass pulled from the glass 
melting furnace.
    Hand glass melting furnace means a glass melting furnace where the 
molten glass is removed from the furnace by a glassworker using a

according to the procedures in this section.
    (c) The owner or operator shall use the following procedures for 
determining monthly volume-weighted average emissions of VOC's in 
kilograms per liter of coating solids applied (G).

[[Page 527]]

    (1) An owner or operator shall use the following procedures for any 
affected facility which does not use a capture system and control device 
to comply with the emissions limit specified under Sec. 60.312. The 
owner or operator shall determine the composition of the coatings by 
formulation data supplied by the manufacturer of the coating or by an 
analysis of each coating, as received, using Method 24. The 
Administrator may require the owner or operator who uses formulation 
data supplied by the manufacturer of the coating to determine the VOC 
content of coatings using Method 24. The owner or operator shall 
determine the volume of coating and the mass of VOC-solvent used for 
thinning purposes from company records on a monthly basis. If a common 
coating distribution system serves more than one affected facility or 
serves both affected and existing facilities, the owner or operator 
shall estimate the volume of coating used at each facility by using the 
average dry weight of coating and the surface area coated by each 
affected and existing facility or by other procedures acceptable to the 
Administrator.
    (i) Calculate the volume-weighted average of the total mass of VOC's 
consumed per unit volume of coating solids applied (G) during each 
calendar month for each affected facility, except as provided under 
Sec. 60.313(c)(2) and (c)(3). Each monthly calculation is considered a 
performance test. Except as provided in paragraph (c)(1)(iv) of this 
section, the volume-weighted average of the total mass of VOC's consumed 
per unit volume of coating solids applied (G) each calendar month will 
be determined by the following procedures.
    (A) Calculate the mass of VOC's used (Mo + Md) 
during each calendar month for each affected facility by the following 
equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.015

([Sigma]LdjDdj will be 0 if no VOC solvent is 
          added to the coatings, as received.)

Where: n is the number of different coatings used during the calendar 
          month and m is the number of different diluent VOC-solvents 
          used during the calendar month.

    (B) Calculate the total volume of coating solids used 
(Ls) in each calendar month for each affected facility by the 
following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.016

Where: n is the number of different coatings used during the calendar 
          month.


Select the appropriate transfer efficiency from table 1. If the owner or 
operator can demonstrate to the satisfaction of the Administrator that 
transfer efficiencies other than those shown are appropriate, the 
Administrator will approve their use on a case-by-case basis. Transfer 
efficiency values for application methods not listed below shall be 
determined by the Administrator on a case-by-case basis. An owner or 
operator must submit sufficient data for the Administrator to judge the 
accuracy of the transfer efficiency claims.

------------------------------------------------------------------------


Where more than one application method is used within a single surface 
coating operation, the owner or operator shall determine the composition 
and volume of each coating applied by each method through a means 
acceptable to the Administrator and compute the weighted average 
transfer efficiency by the following equation:

    (ii) Calculate the volume-weighted average of VOC emissions to the 
atmosphere (N) during the calendar month for each affected facility by 
the following equation:


N = G

    (iii) Where the volume-weighted average mass of VOC discharged to 
the atmosphere per unit volume of coating solids applied (N) is less 
than or equal to 0.90 kilogram per liter, the affected facility is in 
compliance.
    (iv) If each individual coating used by an affected facility has a 
VOC content, as received, which when divided by the lowest transfer 
efficiency at which the coating is applied, results in a value equal to 
or less than 0.90 kilogram per liter, the affected facility is in 
compliance provided no VOC's are added to the coatings during 
distribution or application.
    (2) An owner or operator shall use the following procedures for any

destroys VOC's (e.g., incinerator) to comply with the emission limit 
specified under Sec. 60.312.
    (i) Determine the overall reduction efficiency (R) for the capture 
system and control device. For the initial performance test the overall 
reduction efficiency (R) shall be determined as prescribed in paragraphs

owner or operator may use the most recently determined overall reduction 
efficiency (R) for the performance test providing control device and 
capture system operating conditions have not changed. The procedure in, 
paragraphs (c)(2)(i) (A), (B), and (C), of this section, shall be 
repeated when directed by the Administrator or when the owner or 
operator elects to operate the control device or capture system at 
conditions different from the initial performance test.
    (A) Determine the fraction (F) of total VOC's emitted by an affected 
facility that enters the control device using the following equation:

Where

n is the number of gas streams entering the control device and
m is the number of gas streams emitted directly to the atmosphere.

    (B) Determine the destruction efficiency of the control device (E) 
using values of the volumetric flow rate of each of the gas streams and 
the VOC content (as carbon) of each of the gas streams in and out of the 
device by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.011

Where:

n is the number of gas streams entering the control device, and
m is the number of gas streams leaving the contol device and entering 
          the atmosphere.

    (C) Determine overall reduction efficiency (R) using the following 
equation:

R = EF

    (ii) Calculate the volume-weighted average of the total mass of 
VOC's per unit volume of coating solids applied (G) during each calendar 
month for each affected facility using equations in paragraphs (c)(1)(i) 
(A), (B), and (C) of this section.
    (iii) Calculate the volume-weighted average of VOC emissions to the 
atmosphere (N) during each calendar month by the following equation:

N = G(1-R)

    (iv) If the volume-weighted average mass of VOC's emitted to the 
atmosphere for each calendar month (N) is less than or equal to 0.90 
kilogram per liter of coating solids applied, the affected facility is 
in compliance. Each monthly calculation is a performance test.

[[Page 529]]

    (3) An owner or operator shall use the following procedure for any 
affected facility which uses a control device that recovers the VOC's 
(e.g., carbon adsorber) to comply with the applicable emission limit 
specified under Sec. 60.312.
    (i) Calculate the total mass of VOC's consumed (Mo + 
Md) and the volume-weighted average of the total mass of 
VOC's per unit volume of coating solids applied (G) during each calendar 
month for each affected facility using equations in paragraph (c)(1)(i)

the atmosphere (N) for each calendar month for each affected facility 
using equation in paragraph (c)(2)(iii) of this section.
    (v) If the weighted average mass of VOC's emitted to the atmosphere 
for each calendar month (N) is less than or equal to 0.90 kilogram per 
liter of coating solids applied, the affected facility is in compliance. 
Each monthly calculation is a performance test.

          kilojoules per watt hour, and
F = NOX emission allowance for fuel-bound nitrogen as defined 
          in paragraph (a)(4) of this section.

    (3) The use of F in paragraphs (a)(1) and (2) of this section is 
optional. That is, the owner or operator may choose to apply a 
NOX allowance for fuel-bound nitrogen and determine the 
appropriate F-value in accordance with paragraph (a)(4) of this section 
or may accept an F-value of zero.
    (4) If the owner or operator elects to apply a NOX 
emission allowance for fuel-bound nitrogen, F shall be defined according 
to the nitrogen content of the fuel during the most recent performance 
test required under Sec. 60.8 as follows:

------------------------------------------------------------------------
  Fuel-bound nitrogen (percent by weight)     F (NOX percent by volume)
------------------------------------------------------------------------
N <= .015.................................  0
0.015 0.25.........................  0.005
------------------------------------------------------------------------

Where:

N = the nitrogen content of the fuel (percent by weight).


or:


Manufacturers may develop and submit to EPA custom fuel-bound nitrogen 
allowances for each gas turbine model they manufacture. These fuel-bound 
nitrogen allowances shall be substantiated with data and must be 
approved for use by the Administrator before the initial performance 
test required by Sec. 60.8. Notices of approval of custom fuel-bound 
nitrogen allowances will be published in the Federal Register.
    (b) Electric utility stationary gas turbines with a heat input at

on the lower heating value of the fuel fired and that have commenced 
construction prior to October 3, 1982 are exempt from paragraph (a) of 
this section.
    (f) Stationary gas turbines using water or steam injection for 
control of NOX emissions are exempt from paragraph (a) when 
ice fog is deemed a traffic hazard by the owner or operator of the gas 
turbine.
    (g) Emergency gas turbines, military gas turbines for use in other 
than a garrison facility, military gas turbines installed for use as 
military training facilities, and fire fighting gas turbines are exempt 
from paragraph (a) of this section.
    (h) Stationary gas turbines engaged by manufacturers in research and 
development of equipment for both gas turbine emission control 
techniques and gas turbine efficiency improvements are exempt from 
paragraph (a) on a case-by-case basis as determined by the 
Administrator.
    (i) Exemptions from the requirements of paragraph (a) of this 
section will be granted on a case-by-case basis as determined by the 
Administrator in specific geographical areas where mandatory water 
restrictions are required by governmental agencies because of drought 
conditions. These exemptions will be allowed only while the mandatory 
water restrictions are in effect.
    (j) Stationary gas turbines with a heat input at peak load greater 
than 107.2 gigajoules per hour that commenced construction, 
modification, or reconstruction between the dates of October 3, 1977, 
and January 27, 1982, and were required in the September 10, 1979, 
Federal Register (44 FR 52792) to comply with paragraph (a)(1) of this 
section, except electric utility stationary gas turbines, are exempt

Sec. 60.333  Standard for sulfur dioxide.

    On and after the date on which the performance test required to be 
conducted by Sec. 60.8 is completed, every owner or operator subject to 
the provision of this subpart shall comply with one or the other of the 
following conditions:
    (a) No owner or operator subject to the provisions of this subpart 
shall cause to be discharged into the atmosphere from any stationary gas 
turbine any gases which contain sulfur dioxide in excess of 0.015 
percent by volume at 15 percent oxygen and on a dry basis.
    (b) No owner or operator subject to the provisions of this subpart 
shall burn in any stationary gas turbine any fuel which contains total 
sulfur in excess of 0.8 percent by weight (8000 ppmw).

[44 FR 52798, Sept. 10, 1979, as amended at 69 FR 41360, July 8, 2004]



Sec. 60.334  Monitoring of operations.

    (a) Except as provided in paragraph (b) of this section, the owner 
or operator of any stationary gas turbine subject to the provisions of 
this subpart and using water or steam injection to control 
NOX emissions shall install, calibrate, maintain and operate 
a continuous monitoring system to monitor and record the fuel 
consumption and the ratio of water or steam to fuel being fired in the 
turbine.
    (b) The owner or operator of any stationary gas turbine that 
commenced

[[Page 535]]

construction, reconstruction or modification after October 3, 1977, but 
before July 8, 2004, and which uses water or steam injection to control 
NOX emissions may, as an alternative to operating the 
continuous monitoring system described in paragraph (a) of this section, 
install, certify, maintain, operate, and quality-assure a continuous 
emission monitoring system (CEMS) consisting of NOX and 
O2 monitors. As an alternative, a CO2 monitor may 
be used to adjust the measured NOX concentrations to 15 
percent O2 by either converting the CO2 hourly 
averages to equivalent O2 concentrations using Equation F-14a 
or F-14b in appendix F to part 75 of this chapter and making the 
adjustments to 15 percent O2, or by using the CO2 
readings directly to make the adjustments, as described in Method 20. If 
the option to use a CEMS is chosen, the CEMS shall be installed, 
certified, maintained and operated as follows:
    (1) Each CEMS must be installed and certified according to PS 2 and 
3 (for diluent) of 40 CFR part 60, appendix B, except the 7-day 
calibration drift is based on unit operating days, not calendar days. 
Appendix F, Procedure 1 is not required. The relative accuracy test 
audit (RATA) of the NOX and diluent monitors may be performed 
individually or on a combined basis, i.e., the relative accuracy tests 
of the CEMS may be performed either:
    (i) On a ppm basis (for NOX) and a percent O2 
basis for oxygen; or
    (ii) On a ppm at 15 percent O2 basis; or
    (iii) On a ppm basis (for NOX) and a percent 
CO2 basis (for a CO2 monitor that uses the 
procedures in Method 20 to correct the NOX data to 15 percent 
O2).
    (2) As specified in Sec. 60.13(e)(2), during each full unit 
operating hour, each monitor must complete a minimum of one cycle of 
operation (sampling, analyzing, and data recording) for each 15-minute 
quadrant of the hour, to validate the hour. For partial unit operating 
hours, at least one valid data point must be obtained for each quadrant 
of the hour in which the unit operates. For unit operating hours in 
which required quality assurance and maintenance activities are 
performed on the CEMS, a minimum of two valid data points (one in each 
of two quadrants) are required to validate the hour.
    (3) For purposes of identifying excess emissions, CEMS data must be 
reduced to hourly averages as specified in Sec. 60.13(h).
    (i) For each unit operating hour in which a valid hourly average, as 
described in paragraph (b)(2) of this section, is obtained for both 
NOX and diluent, the data acquisition and handling system 
must calculate and record the hourly NOX emissions in the 
units of the applicable NOX emission standard under Sec. 
60.332(a), i.e., percent NOX by volume, dry basis, corrected 
to 15 percent O2 and International Organization for 
Standardization (ISO) standard conditions (if required as given in Sec. 
60.335(b)(1)). For any hour in which the hourly average O2 
concentration exceeds 19.0 percent O2, a diluent cap value of 
19.0 percent O2 may be used in the emission calculations.
    (ii) A worst case ISO correction factor may be calculated and 
applied using historical ambient data. For the purpose of this 
calculation, substitute the maximum humidity of ambient air (Ho), 
minimum ambient temperature (Ta), and minimum combustor inlet 
absolute pressure (Po) into the ISO correction equation.
    (iii) If the owner or operator has installed a NOX CEMS 
to meet the requirements of part 75 of this chapter, and is continuing 
to meet the ongoing requirements of part 75 of this chapter, the CEMS 
may be used to meet the requirements of this section, except that the 
missing data substitution methodology provided for at 40 CFR part 75, 
subpart D, is not required for purposes of identifying excess emissions. 
Instead, periods of missing CEMS data are to be reported as monitor 
downtime in the excess emissions and monitoring performance report 
required in Sec. 60.7(c).
    (c) For any turbine that commenced construction, reconstruction or 
modification after October 3, 1977, but before July 8, 2004, and which 
does not use steam or water injection to control NOX 
emissions, the owner or operator may, but is not required to, for 
purposes of determining excess emissions,

[[Page 536]]

use a CEMS that meets the requirements of paragraph (b) of this section. 
Also, if the owner or operator has previously submitted and received 
EPA, State, or local permitting authority approval of a procedure for 
monitoring compliance with the applicable NOX emission limit 
under Sec. 60.332, that approved procedure may continue to be used.
    (d) The owner or operator of any new turbine constructed after July 
8, 2004, and which uses water or steam injection to control 
NOX emissions may elect to use either the requirements in 
paragraph (a) of this section for continuous water or steam to fuel 
ratio monitoring or may use a NOX CEMS installed, certified, 
operated, maintained, and quality-assured as described in paragraph (b) 
of this section.
    (e) The owner or operator of any new turbine that commences 
construction after July 8, 2004, and which does not use water or steam 
injection to control NOX emissions, may, but is not required 
to, elect to use a NOX CEMS installed, certified, operated, 
maintained, and quality-assured as described in paragraph (b) of this 
section. Other acceptable monitoring approaches include periodic testing 
approved by EPA or the State or local permitting authority or continuous 
parameter monitoring as described in paragraph (f) of this section.
    (f) The owner or operator of a new turbine that commences 
construction after July 8, 2004, which does not use water or steam 
injection to control NOX emissions may, but is not required 
to, perform continuous parameter monitoring as follows:
    (1) For a diffusion flame turbine without add-on selective catalytic 
reduction controls (SCR), the owner or operator shall define at least 
four parameters indicative of the unit's NOX formation 
characteristics and shall monitor these parameters continuously.
    (2) For any lean premix stationary combustion turbine, the owner or 
operator shall continuously monitor the appropriate parameters to 
determine whether the unit is operating in low-NOX mode.
    (3) For any turbine that uses SCR to reduce NOX 
emissions, the owner or operator shall continuously monitor appropriate 
parameters to verify the proper operation of the emission controls.
    (4) For affected units that are also regulated under part 75 of this 
chapter, if the owner or operator elects to monitor NOX 
emission rate using the methodology in appendix E to part 75 of this 
chapter, or the low mass emissions methodology in Sec. 75.19 of this 
chapter, the requirements of this paragraph (f) may be met by performing 
the parametric monitoring described in section 2.3 of appendix E or in 
Sec. 75.19(c)(1)(iv)(H) of this chapter.
    (g) The steam or water to fuel ratio or other parameters that are 
continuously monitored as described in paragraphs (a), (d) or (f) of 
this section shall be monitored during the performance test required 
under Sec. 60.8, to establish acceptable values and ranges. The owner 
or operator may supplement the performance test data with engineering 
analyses, design specifications, manufacturer's recommendations and 
other relevant information to define the acceptable parametric ranges 
more precisely. The owner or operator shall develop and keep on-site a 
parameter monitoring plan which explains the procedures used to document 
proper operation of the NOX emission controls. The plan shall 
include the parameter(s) monitored and the acceptable range(s) of the 
parameter(s) as well as the basis for designating the parameter(s) and 
acceptable range(s). Any supplemental data such as engineering analyses, 
design specifications, manufacturer's recommendations and other relevant 
information shall be included in the monitoring plan. For affected units 
that are also subject to part 75 of this chapter and that use the low 
mass emissions methodology in Sec. 75.19 of this chapter or the 
NOX emission measurement methodology in appendix E to part 
75, the owner or operator may meet the requirements of this paragraph by 
developing and keeping on-site (or at a central location for unmanned 
facilities) a quality-assurance plan, as described in Sec. 75.19 (e)(5) 
or in section 2.3 of appendix E and section 1.3.6 of appendix B to part 
75 of this chapter.

[[Page 537]]

    (h) The owner or operator of any stationary gas turbine subject to 
the provisions of this subpart:
    (1) Shall monitor the total sulfur content of the fuel being fired 
in the turbine, except as provided in paragraph (h)(3) of this section. 
The sulfur content of the fuel must be determined using total sulfur 
methods described in Sec. 60.335(b)(10). Alternatively, if the total 
sulfur content of the gaseous fuel during the most recent performance 
test was less than 0.4 weight percent (4000 ppmw), ASTM D4084-82, 94, 
D5504-01, D6228-98, or Gas Processors Association Standard 2377-86 (all 
of which are incorporated by reference-see Sec. 60.17), which measure 
the major sulfur compounds may be used; and
    (2) Shall monitor the nitrogen content of the fuel combusted in the 
turbine, if the owner or operator claims an allowance for fuel bound 
nitrogen (i.e., if an F-value greater than zero is being or will be used 
by the owner or operator to calculate STD in Sec. 60.332). The nitrogen 
content of the fuel shall be determined using methods described in Sec. 
60.335(b)(9) or an approved alternative.
    (3) Notwithstanding the provisions of paragraph (h)(1) of this 
section, the owner or operator may elect not to monitor the total sulfur 
content of the gaseous fuel combusted in the turbine, if the gaseous 
fuel is demonstrated to meet the definition of natural gas in Sec. 
60.331(u), regardless of whether an existing custom schedule approved by 
the administrator for subpart GG requires such monitoring. The owner or 
operator shall use one of the following sources of information to make 
the required demonstration:
    (i) The gas quality characteristics in a current, valid purchase 
contract, tariff sheet or transportation contract for the gaseous fuel, 
specifying that the maximum total sulfur content of the fuel is 20.0 
grains/100 scf or less; or
    (ii) Representative fuel sampling data which show that the sulfur 
content of the gaseous fuel does not exceed 20 grains/100 scf. At a 
minimum, the amount of fuel sampling data specified in section 2.3.1.4 
or 2.3.2.4 of appendix D to part 75 of this chapter is required.
    (4) For any turbine that commenced construction, reconstruction or 
modification after October 3, 1977, but before July 8, 2004, and for 
which a custom fuel monitoring schedule has previously been approved, 
the owner or operator may, without submitting a special petition to the 
Administrator, continue monitoring on this schedule.
    (i) The frequency of determining the sulfur and nitrogen content of 
the fuel shall be as follows:
    (1) Fuel oil. For fuel oil, use one of the total sulfur sampling 
options and the associated sampling frequency described in sections 
2.2.3, 2.2.4.1, 2.2.4.2, and 2.2.4.3 of appendix D to part 75 of this 
chapter (i.e., flow proportional sampling, daily sampling, sampling from 
the unit's storage tank after each addition of fuel to the tank, or 
sampling each delivery prior to combining it with fuel oil already in 
the intended storage tank). If an emission allowance is being claimed 
for fuel-bound nitrogen, the nitrogen content of the oil shall be 
determined and recorded once per unit operating day.
    (2) Gaseous fuel. Any applicable nitrogen content value of the 
gaseous fuel shall be determined and recorded once per unit operating 
day. For owners and operators that elect not to demonstrate sulfur 
content using options in paragraph (h)(3) of this section, and for which 
the fuel is supplied without intermediate bulk storage, the sulfur 
content value of the gaseous fuel shall be determined and recorded once 
per unit operating day.
    (3) Custom schedules. Notwithstanding the requirements of paragraph 
(i)(2) of this section, operators or fuel vendors may develop custom 
schedules for determination of the total sulfur content of gaseous 
fuels, based on the design and operation of the affected facility and 
the characteristics of the fuel supply. Except as provided in paragraphs 
(i)(3)(i) and (i)(3)(ii) of this section, custom schedules shall be 
substantiated with data and shall be approved by the Administrator 
before they can be used to comply with the standard in Sec. 60.333.
    (i) The two custom sulfur monitoring schedules set forth in 
paragraphs (i)(3)(i)(A) through (D) and in paragraph (i)(3)(ii) of this 
section are acceptable, without prior Administrative approval:

[[Page 538]]

    (A) The owner or operator shall obtain daily total sulfur content 
measurements for 30 consecutive unit operating days, using the 
applicable methods specified in this subpart. Based on the results of 
the 30 daily samples, the required frequency for subsequent monitoring 
of the fuel's total sulfur content shall be as specified in paragraph 
(i)(3)(i)(B), (C), or (D) of this section, as applicable.
    (B) If none of the 30 daily measurements of the fuel's total sulfur 
content exceeds 0.4 weight percent (4000 ppmw), subsequent sulfur 
content monitoring may be performed at 12 month intervals. If any of the 
samples taken at 12-month intervals has a total sulfur content between 
0.4 and 0.8 weight percent (4000 and 8000 ppmw), follow the procedures 
in paragraph (i)(3)(i)(C) of this section. If any measurement exceeds 
0.8 weight percent (8000 ppmw), follow the procedures in paragraph 
(i)(3)(i)(D) of this section.
    (C) If at least one of the 30 daily measurements of the fuel's total 
sulfur content is between 0.4 and 0.8 weight percent (4000 and 8000 
ppmw), but none exceeds 0.8 weight percent (8000 ppmw), then:
    (1) Collect and analyze a sample every 30 days for three months. If 
any sulfur content measurement exceeds 0.8 weight percent (8000 ppmw), 
follow the procedures in paragraph (i)(3)(i)(D) of this section. 
Otherwise, follow the procedures in paragraph (i)(3)(i)(C)(2) of this 
section.
    (2) Begin monitoring at 6-month intervals for 12 months. If any 
sulfur content measurement exceeds 0.8 weight percent (8000 ppmw), 
follow the procedures in paragraph (i)(3)(i)(D) of this section. 
Otherwise, follow the procedures in paragraph (i)(3)(i)(C)(3) of this 
section.
    (3) Begin monitoring at 12-month intervals. If any sulfur content 
measurement exceeds 0.8 weight percent (8000 ppmw), follow the 
procedures in paragraph (i)(3)(i)(D) of this section. Otherwise, 
continue to monitor at this frequency.
    (D) If a sulfur content measurement exceeds 0.8 weight percent (8000 
ppmw), immediately begin daily monitoring according to paragraph 
(i)(3)(i)(A) of this section. Daily monitoring shall continue until 30 
consecutive daily samples, each having a sulfur content no greater than 
0.8 weight percent (8000 ppmw), are obtained. At that point, the 
applicable procedures of paragraph (i)(3)(i)(B) or (C) of this section 
shall be followed.
    (ii) The owner or operator may use the data collected from the 720-
hour sulfur sampling demonstration described in section 2.3.6 of 
appendix D to part 75 of this chapter to determine a custom sulfur 
sampling schedule, as follows:
    (A) If the maximum fuel sulfur content obtained from the 720 hourly 
samples does not exceed 20 grains/100 scf (i.e., the maximum total 
sulfur content of natural gas as defined in Sec. 60.331(u)), no 
additional monitoring of the sulfur content of the gas is required, for 
the purposes of this subpart.
    (B) If the maximum fuel sulfur content obtained from any of the 720 
hourly samples exceeds 20 grains/100 scf, but none of the sulfur content 
values (when converted to weight percent sulfur) exceeds 0.4 weight 
percent (4000 ppmw), then the minimum required sampling frequency shall 
be one sample at 12 month intervals.
    (C) If any sample result exceeds 0.4 weight percent sulfur (4000 
ppmw), but none exceeds 0.8 weight percent sulfur (8000 ppmw), follow 
the provisions of paragraph (i)(3)(i)(C) of this section.
    (D) If the sulfur content of any of the 720 hourly samples exceeds 
0.8 weight percent (8000 ppmw), follow the provisions of paragraph 
(i)(3)(i)(D) of this section.
    (j) For each affected unit that elects to continuously monitor 
parameters or emissions, or to periodically determine the fuel sulfur 
content or fuel nitrogen content under this subpart, the owner or 
operator shall submit reports of excess emissions and monitor downtime, 
in accordance with Sec. 60.7(c). Excess emissions shall be reported for 
all periods of unit operation, including startup, shutdown and 
malfunction. For the purpose of reports required under Sec. 60.7(c), 
periods of excess emissions and monitor downtime that shall be reported 
are defined as follows:
    (1) Nitrogen oxides.
    (i) For turbines using water or steam to fuel ratio monitoring:

[[Page 539]]

    (A) An excess emission shall be any unit operating hour for which 
the average steam or water to fuel ratio, as measured by the continuous 
monitoring system, falls below the acceptable steam or water to fuel 
ratio needed to demonstrate compliance with Sec. 60.332, as established 
during the performance test required in Sec. 60.8. Any unit operating 
hour in which no water or steam is injected into the turbine shall also 
be considered an excess emission.
    (B) A period of monitor downtime shall be any unit operating hour in 
which water or steam is injected into the turbine, but the essential 
parametric data needed to determine the steam or water to fuel ratio are 
unavailable or invalid.
    (C) Each report shall include the average steam or water to fuel 
ratio, average fuel consumption, ambient conditions (temperature, 
pressure, and humidity), gas turbine load, and (if applicable) the 
nitrogen content of the fuel during each excess emission. You do not 
have to report ambient conditions if you opt to use the worst case ISO 
correction factor as specified in Sec. 60.334(b)(3)(ii), or if you are 
not using the ISO correction equation under the provisions of Sec. 
60.335(b)(1).
    (ii) If the owner or operator elects to take an emission allowance 
for fuel bound nitrogen, then excess emissions and periods of monitor 
downtime are as described in paragraphs (j)(1)(ii)(A) and (B) of this 
section.
    (A) An excess emission shall be the period of time during which the 
fuel-bound nitrogen (N) is greater than the value measured during the 
performance test required in Sec. 60.8 and used to determine the 
allowance. The excess emission begins on the date and hour of the sample 
which shows that N is greater than the performance test value, and ends 
with the date and hour of a subsequent sample which shows a fuel 
nitrogen content less than or equal to the performance test value.
    (B) A period of monitor downtime begins when a required sample is 
not taken by its due date. A period of monitor downtime also begins on 
the date and hour that a required sample is taken, if invalid results 
are obtained. The period of monitor downtime ends on the date and hour 
of the next valid sample.
    (iii) For turbines using NOX and diluent CEMS:
    (A) An hour of excess emissions shall be any unit operating hour in 
which the 4-hour rolling average NOX concentration exceeds 
the applicable emission limit in Sec. 60.332(a)(1) or (2). For the 
purposes of this subpart, a ``4-hour rolling average NOX 
concentration'' is the arithmetic average of the average NOX 
concentration measured by the CEMS for a given hour (corrected to 15 
percent O2 and, if required under Sec. 60.335(b)(1), to ISO 
standard conditions) and the three unit operating hour average 
NOX concentrations immediately preceding that unit operating 
hour.
    (B) A period of monitor downtime shall be any unit operating hour in 
which sufficient data are not obtained to validate the hour, for either 
NOX concentration or diluent (or both).
    (C) Each report shall include the ambient conditions (temperature, 
pressure, and humidity) at the time of the excess emission period and 
(if the owner or operator has claimed an emission allowance for fuel 
bound nitrogen) the nitrogen content of the fuel during the period of 
excess emissions. You do not have to report ambient conditions if you 
opt to use the worst case ISO correction factor as specified in Sec. 
60.334(b)(3)(ii), or if you are not using the ISO correction equation 
under the provisions of Sec. 60.335(b)(1).
    (iv) For owners or operators that elect, under paragraph (f) of this 
section, to monitor combustion parameters or parameters that document 
proper operation of the NOX emission controls:
    (A) An excess emission shall be a 4-hour rolling unit operating hour 
average in which any monitored parameter does not achieve the target 
value or is outside the acceptable range defined in the parameter 
monitoring plan for the unit.
    (B) A period of monitor downtime shall be a unit operating hour in 
which any of the required parametric data are either not recorded or are 
invalid.
    (2) Sulfur dioxide. If the owner or operator is required to monitor 
the sulfur

[[Page 540]]

content of the fuel under paragraph (h) of this section:
    (i) For samples of gaseous fuel and for oil samples obtained using 
daily sampling, flow proportional sampling, or sampling from the unit's 
storage tank, an excess emission occurs each unit operating hour 
included in the period beginning on the date and hour of any sample for 
which the sulfur content of the fuel being fired in the gas turbine 
exceeds 0.8 weight percent and ending on the date and hour that a 
subsequent sample is taken that demonstrates compliance with the sulfur 
limit.
    (ii) If the option to sample each delivery of fuel oil has been 
selected, the owner or operator shall immediately switch to one of the 
other oil sampling options (i.e., daily sampling, flow proportional 
sampling, or sampling from the unit's storage tank) if the sulfur 
content of a delivery exceeds 0.8 weight percent. The owner or operator 
shall continue to use one of the other sampling options until all of the 
oil from the delivery has been combusted, and shall evaluate excess 
emissions according to paragraph (j)(2)(i) of this section. When all of 
the fuel from the delivery has been burned, the owner or operator may 
resume using the as-delivered sampling option.
    (iii) A period of monitor downtime begins when a required sample is 
not taken by its due date. A period of monitor downtime also begins on 
the date and hour of a required sample, if invalid results are obtained. 
The period of monitor downtime shall include only unit operating hours,

Sec. 60.335  Test methods and procedures.

    (a) The owner or operator shall conduct the performance tests 
required in Sec. 60.8, using either
    (1) EPA Method 20,
    (2) ASTM D6522-00 (incorporated by reference, see Sec. 60.17), or
    (3) EPA Method 7E and either EPA Method 3 or 3A in appendix A to 
this part, to determine NOX and diluent concentration.
    (4) Sampling traverse points are to be selected following Method 20 
or Method 1, (non-particulate procedures) and sampled for equal time 
intervals. The sampling shall be performed with a traversing single-hole 
probe or, if feasible, with a stationary multi-hole probe that samples 
each of the points sequentially. Alternatively, a multi-hole probe 
designed and documented to sample equal volumes from each hole may be 
used to sample simultaneously at the required points.
    (5) Notwithstanding paragraph (a)(4) of this section, the owner or 
operator may test at few points than are specified in Method 1 or Method 
20 if the following conditions are met:
    (i) You may perform a stratification test for NOX and 
diluent pursuant to
    (A) [Reserved]
    (B) The procedures specified in section 6.5.6.1(a) through (e) 
appendix A to part 75 of this chapter.
    (ii) Once the stratification sampling is completed, the owner or 
operator may use the following alternative sample point selection 
criteria for the performance test:
    (A) If each of the individual traverse point NOX 
concentrations, normalized to 15 percent O2, is within 10 
percent of the mean normalized concentration for all traverse points, 
then you may use 3 points (located either 16.7, 50.0, and 83.3

[[Page 541]]

percent of the way across the stack or duct, or, for circular stacks or 
ducts greater than 2.4 meters (7.8 feet) in diameter, at 0.4, 1.2, and 
2.0 meters from the wall). The 3 points shall be located along the 
measurement line that exhibited the highest average normalized 
NOX concentration during the stratification test; or
    (B) If each of the individual traverse point NOX 
concentrations, normalized to 15 percent O2, is within 5 
percent of the mean normalized concentration for all traverse points, 
then you may sample at a single point, located at least 1 meter from the 
stack wall or at the stack centroid.
    (6) Other acceptable alternative reference methods and procedures 
are given in paragraph (c) of this section.
    (b) The owner or operator shall determine compliance with the 
applicable nitrogen oxides emission limitation in Sec. 60.332 and shall 
meet the performance test requirements of Sec. 60.8 as follows:
    (1) For each run of the performance test, the mean nitrogen oxides 
emission concentration (NOXo) corrected to 15 percent 
O2 shall be corrected to ISO standard conditions using the 
following equation. Notwithstanding this requirement, use of the ISO 
correction equation is optional for: Lean premix stationary combustion 
turbines; units used in association with heat recovery steam generators 
(HRSG) equipped with duct burners; and units equipped with add-on 
emission control devices:

NOX = (NOXo)(Pr/Po)\0.5\ 
e19 (Ho-0.00633) (288 [deg]K/Ta)\1.53\

Where:

NOX = emission concentration of NOX at 15 percent 
          O2 and ISO standard ambient conditions, ppm by 
          volume, dry basis,
NOXo = mean observed NOX concentration, ppm by 
          volume, dry basis, at 15 percent O2,
Pr = reference combustor inlet absolute pressure at 101.3 
kilopascals ambient pressure. Alternatively, you may use 760 mm Hg 
(29.92 in Hg),
Po = observed combustor inlet absolute pressure at test, mm 
Hg. Alternatively, you may use the barometric pressure for the date of 
the test,
Ho = observed humidity of ambient air, g H2O/g 
          air,
e = transcendental constant, 2.718, and
Ta = ambient temperature, [deg]K.

    (2) The 3-run performance test required by Sec. 60.8 must be 
performed within 5 percent at 30, 50, 75, and 90-to-100 percent of peak 
load or at four evenly-spaced load points in the normal operating range 
of the gas turbine, including the minimum point in the operating range 
and 90-to-100 percent of peak load, or at the highest achievable load 
point if 90-to-100 percent of peak load cannot be physically achieved in 
practice. If the turbine combusts both oil and gas as primary or backup 
fuels, separate performance testing is required for each fuel. 
Notwithstanding these requirements, performance testing is not required 
for any emergency fuel (as defined in Sec. 60.331).
    (3) For a combined cycle turbine system with supplemental heat (duct 
burner), the owner or operator may elect to measure the turbine 
NOX emissions after the duct burner rather than directly 
after the turbine. If the owner or operator elects to use this 
alternative sampling location, the applicable NOX emission 
limit in Sec. 60.332 for the combustion turbine must still be met.
    (4) If water or steam injection is used to control NOX 
with no additional post-combustion NOX control and the owner 
or operator chooses to monitor the steam or water to fuel ratio in 
accordance with Sec. 60.334(a), then that monitoring system must be 
operated concurrently with each EPA Method 20, ASTM D6522-00 
(incorporated by reference, see Sec. 60.17), or EPA Method 7E run and 
shall be used to determine the fuel consumption and the steam or water 
to fuel ratio necessary to comply with the applicable Sec. 60.332 
NOX emission limit.
    (5) If the owner operator elects to claim an emission allowance for 
fuel bound nitrogen as described in Sec. 60.332, then concurrently with 
each reference method run, a representative sample of the fuel used 
shall be collected and analyzed, following the applicable procedures 
described in Sec. 60.335(b)(9). These data shall be used to determine 
the maximum fuel nitrogen content for which the established water (or 
steam) to fuel ratio will be valid.

[[Page 542]]

    (6) If the owner or operator elects to install a CEMS, the 
performance evaluation of the CEMS may either be conducted separately 
(as described in paragraph (b)(7) of this section) or as part of the 
initial performance test of the affected unit.
    (7) If the owner or operator elects to install and certify a 
NOX CEMS under Sec. 60.334(e), then the initial performance 
test required under Sec. 60.8 may be done in the following alternative 
manner:
    (i) Perform a minimum of 9 reference method runs, with a minimum 
time per run of 21 minutes, at a single load level, between 90 and 100 
percent of peak (or the highest physically achievable) load.
    (ii) Use the test data both to demonstrate compliance with the 
applicable NOX emission limit under Sec. 60.332 and to 
provide the required reference method data for the RATA of the CEMS 
described under Sec. 60.334(b).
    (iii) The requirement to test at three additional load levels is 
waived.
    (8) If the owner or operator elects under Sec. 60.334(f) to monitor 
combustion parameters or parameters indicative of proper operation of 
NOX emission controls, the appropriate parameters shall be 
continuously monitored and recorded during each run of the initial 
performance test, to establish acceptable operating ranges, for purposes 
of the parameter monitoring plan for the affected unit, as specified in 
Sec. 60.334(g).
    (9) To determine the fuel bound nitrogen content of fuel being fired 
(if an emission allowance is claimed for fuel bound nitrogen), the owner 
or operator may use equipment and procedures meeting the requirements 
of:
    (i) For liquid fuels, ASTM D2597-94 (Reapproved 1999), D6366-99, 
D4629-02, D5762-02 (all of which are incorporated by reference, see 
Sec. 60.17); or
    (ii) For gaseous fuels, shall use analytical methods and procedures 
that are accurate to within 5 percent of the instrument range and are 
approved by the Administrator.
    (10) If the owner or operator is required under Sec. 60.334(i)(1) 
or (3) to periodically determine the sulfur content of the fuel 
combusted in the turbine, a minimum of three fuel samples shall be 
collected during the performance test. Analyze the samples for the total 
sulfur content of the fuel using:
    (i) For liquid fuels, ASTM D129-00, D2622-98, D4294-02, D1266-98, 
D5453-00 or D1552-01 (all of which are incorporated by reference, see 
Sec. 60.17); or
    (ii) For gaseous fuels, ASTM D1072-80, 90 (Reapproved 1994); D3246-
81, 92, 96; D4468-85 (Reapproved 2000); or D6667-01 (all of which are 
incorporated by reference, see Sec. 60.17). The applicable ranges of 
some ASTM methods mentioned above are not adequate to measure the levels 
of sulfur in some fuel gases. Dilution of samples before analysis (with 
verification of the dilution ratio) may be used, subject to the prior 
approval of the Administrator.
    (11) The fuel analyses required under paragraphs (b)(9) and (b)(10) 
of this section may be performed by the owner or operator, a service 
contractor retained by the owner or operator, the fuel vendor, or any 
other qualified agency.
    (c) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) Instead of using the equation in paragraph (b)(1) of this 
section, manufacturers may develop ambient condition correction factors 
to adjust the nitrogen oxides emission level measured by the performance 
test as provided in Sec. 60.8 to ISO standard day conditions.

equivalent standard for the total exhaust from the commonly controlled 
facilities must be determined using equation 1 to this paragraph (b) as 
follows:
[GRAPHIC] [TIFF OMITTED] TR23FE23.000

Where:

Se = is the equivalent standard for the total exhaust stream, 
          mg/dscm (gr/dscf).
Sa = is the actual standard for each exhaust stream ducted to 
          the control device, mg/dscm (gr/dscf).
N = is the total number of exhaust streams ducted to the control device.

[[Page 549]]

Qsda = is the dry standard volumetric flow rate of the 
          effluent gas stream from each facility ducted to the control 
          device, dscm/hr (dscf/hr).
QsdT = is the total dry standard volumetric flow rate of all 
          effluent gas streams ducted to the control device, dscm/hr 
          (dscf/hr).

    (c) The owner or operator must prepare, and at all times operate 
according to, a fugitive dust mitigation plan that describes in detail 
the measures that will be put in place and implemented to control 
fugitive dust emissions in the lead oxide unloading and storage areas. 
You must prepare a fugitive dust mitigation plan according to the 
requirements in paragraphs (c)(1) and (2) of this section.
    (1) The owner or operator must submit the fugitive dust mitigation 
plan to the Administrator or delegated authority for review and approval 
when initially developed and any time changes are made.
    (2) The fugitive dust mitigation plan must at a minimum include the 
requirements specified in paragraphs (c)(2)(i) through (iv) of this 
section.
    (i) Lead oxide unloading and storage areas. Surfaces used for 
vehicular material transfer activity must be cleaned at least once per 
month, by wet wash or a vacuum equipped with a filter rated by the 
manufacturer to achieve 99.97 percent capture efficiency for 0.3 micron 
particles in a manner that does not generate fugitive lead dust, except 
when sand or a similar material has been spread on the area to provide 
traction on ice or snow.
    (ii) Spills in lead oxide unloading and storage areas. For any leak 
or spill that occurs during the unloading and storage process, complete 
washing or vacuuming the area to remove all spilled or leaked lead 
bearing material within 2 hours of the leak or spill occurrence.
    (iii) Materials storage. Dust forming materials (that contain lead 
or lead compounds) must be stored in sealed, leak-proof containers or in 
a total enclosure.
    (iv) Records. The fugitive dust mitigation plan must specify that 
records be maintained of all cleaning performed under paragraph 
(c)(2)(i) and (ii) of this section.



Sec. 60.373a  Monitoring of emissions and operations.

    (a) The owner or operator of any lead acid battery manufacturing 
facility subject to the provisions of this subpart and controlled by a 
scrubbing system(s) must install, calibrate, maintain, and operate a 
monitoring device(s) that measures and records the liquid flow rate and 
pressure drop across the scrubbing system(s) at least once every 15 
minutes. The monitoring device must have an accuracy of 5 percent over its operating range. The operating liquid 
flow rate must be maintained within 10 percent of 
the average liquid flowrate during the most recent performance test. If 
a liquid flow rate or pressure drop is observed outside of the normal 
operational ranges as determined during the most recent performance 
test, you must record the incident and take immediate corrective 
actions. You must also record the corrective actions taken. You must 
submit an excess emissions and monitoring systems performance report and 
summary report required under Sec. 60.375a(c).
    (b) Emissions points controlled by a fabric filter without a 
secondary filter must meet the requirements of paragraphs (b)(1) and (2) 
of this section and either paragraph (b)(3) or (4) of this section. New 
lead acid battery plants with emission points controlled by a fabric 
filter without a secondary filter must meet the requirements of 
paragraph (b)(5) of this section. Fabric filters equipped with a high 
efficiency particulate air (HEPA) filter or other secondary filter must 
comply with the requirements specified in paragraphs (b)(1) and (6) of 
this section.
    (1) You must perform quarterly inspections and maintenance to ensure 
proper performance of each fabric filter. This includes inspection of 
structural and filter integrity.
    (2) If it is not possible for you to take the corrective actions 
specified in paragraph (b)(3)(iii) or (iv) of this section for a process 
or fabric filter control device, you must keep at least one replacement 
fabric filter onsite at all times for that process or fabric filter 
control device. The characteristics of the replacement filters must be 
the same as the current fabric filters in use

[[Page 550]]

or have characteristics that would achieve equal or greater emission 
reductions.
    (3) Install, maintain, and operate a pressure drop monitoring device 
to measure the differential pressure drop across the fabric filter 
during all times when the process is operating. The pressure drop must 
be recorded at least twice per day (at least 8 hours apart) if the 
results of the most recent performance test indicate that emissions from 
the facility are greater than 50 percent of the applicable lead 
emissions limit in Sec. 60.372a(a)(1) through (6). The pressure drop 
must be recorded at least once per day if the results of the most recent 
performance test indicate that emissions are less than or equal to 50 
percent of the applicable lead emissions limit in Sec. 60.372a(a)(1) 
through (6). If a pressure drop is observed outside of the normal 
operational ranges as specified by the manufacturer, you must record the 
incident and take immediate corrective actions. You must submit an 
excess emissions and continuous monitoring system performance report and 
summary report required under Sec. 60.375a(c). You must also record the 
corrective actions taken and verify pressure drop is within normal 
operational range. These corrective actions may include but not be 
limited to those provided in paragraphs (b)(3)(i) through (iv) of this 
section.
    (i) Inspecting the filter and filter housing for air leaks and torn 
or broken filters.
    (ii) Replacing defective filter media, or otherwise repairing the 
control device.
    (iii) Sealing off a defective control device by routing air to other 
control devices.
    (iv) Shutting down the process producing the lead emissions.
    (4) Conduct a visible emissions observation using EPA Method 9 (6 
minutes) or EPA Method 22 (5 minutes) of appendix A to this part while 
the process is in operation to verify that no visible emissions are 
occurring at the discharge point to the atmosphere from any emissions 
source subject to the requirements of Sec. 60.372a(a) or (b). The 
visible emissions observation must be conducted at least twice daily (at 
least 6 hours apart) if the results of the most recent performance test 
indicate that emissions are greater than 50 percent of the applicable 
lead emissions limit in Sec. 60.372a(a)(1) through (6). The visible 
emissions observation must be conducted at least once per day if the 
results of the most recent performance test indicate that emissions are 
less than or equal to 50 percent of the applicable lead emissions limit 
in Sec. 60.372a(a)(1) through (6). If visible emissions are detected, 
you must record the incident and submit this information in an excess 
emissions and continuous monitoring system performance report and 
summary report required under Sec. 60.375a(c) and take immediate 
corrective action. You must also record the corrective actions taken. 
These corrective actions may include, but are not limited to, those 
provided in paragraphs (b)(3)(i) through (iv) of this section.
    (5) If the lead acid battery manufacturing plant was constructed 
after February 23, 2022, and have emissions points controlled by a 
fabric filter, you must install and operate a bag leak detection system 
that meets the specifications and requirements in paragraphs (b)(5)(i) 
through (ix) of this section. For any other affected facility listed in 
Sec. 60.370a(b) that was constructed, modified, or reconstructed after 
February 23, 2022, that operates a bag leak detection system, the bag 
leak detection system must meet the specifications and requirements in 
paragraphs (b)(5)(i) through (ix) of this section. Emission points 
controlled by a fabric filter that is equipped with, and monitored with, 
a bag leak detection system meeting the specifications and requirements 
in paragraphs (b)(5)(i) through (ix) of this section may have the 
inspections required in paragraph (b)(1) of this section performed 
semiannually.
    (i) The bag leak detection system must be certified by the 
manufacturer to be capable of detecting particulate matter as lead 
emissions at concentrations at or below the values in Sec. 60.372a(a), 
as applicable to the process for which the fabric filter is used to 
control emissions. Where the fabric filter is used as a control device 
for more than one process, the lowest applicable value in Sec. 
60.372a(a) must be used.

[[Page 551]]

    (ii) The bag leak detection system sensor must provide output of 
relative particulate matter loadings.
    (iii) The bag leak detection system must be equipped with an alarm 
system that will alarm when an increase in relative particulate loadings 
is detected over a preset level.
    (iv) You must install and operate the bag leak detection system in a 
manner consistent with the guidance provided in ``Office of Air Quality 
Planning and Standards (OAQPS) Fabric Filter Bag Leak Detection 
Guidance'' (EPA-454/R-98-015) (incorporated by reference, see Sec. 
60.17) and the manufacturer's written specifications and recommendations 
for installation, operation, and adjustment of the system.
    (v) The initial adjustment of the system must, at a minimum, consist 
of establishing the baseline output by adjusting the sensitivity (range) 
and the averaging period of the device and establishing the alarm set 
points and the alarm delay time.
    (vi) Following initial adjustment, you must not adjust the 
sensitivity or range, averaging period, alarm set points, or alarm delay 
time, except as detailed in the approved standard operating procedures 
manual required under paragraph (b)(2)(ix) of this section. You cannot 
increase the sensitivity by more than 100 percent or decrease the 
sensitivity by more than 50 percent over a 365-day period unless such 
adjustment follows a complete fabric filter inspection that demonstrates 
that the fabric filter is in good operating condition.
    (vii) For negative pressure, induced air baghouses, and positive 
pressure baghouses that are discharged to the atmosphere through a 
stack, you must install the bag leak detector downstream of the fabric 
filter.
    (viii) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (ix) You must develop a standard operating procedures manual for the 
bag leak detection system that includes procedures for making system 
adjustments and a corrective action plan, which specifies the procedures 
to be followed in the case of a bag leak detection system alarm. The 
corrective action plan must include, at a minimum, the procedures that 
you will use to determine and record the time and cause of the alarm as 
well as the corrective actions taken to minimize emissions as specified 
in paragraphs (b)(5)(ix)(A) and (B) of this section.
    (A) The procedures used to determine the cause of the alarm must be 
initiated within 30 minutes of the alarm.
    (B) The cause of the alarm must be alleviated by taking the 
necessary corrective action(s) that may include, but not be limited to, 
those listed in paragraphs (b)(5)(ix)(B)(1) through (6) of this section.
    (1) Inspecting the baghouse for air leaks, torn or broken filter 
elements, or any other malfunction that may cause an increase in 
emissions.
    (2) Sealing off defective bags or filter media.
    (3) Replacing defective bags or filter media, or otherwise repairing 
the control device.
    (4) Sealing off defective baghouse compartment.
    (5) Cleaning the bag leak detection system probe, or otherwise 
repairing the bag leak detection system.
    (6) Shutting down the process producing the lead emissions.
    (6) Emissions points controlled by a fabric filter equipped with a 
secondary filter, such as a HEPA filter, are exempt from the requirement 
in paragraph (b)(5) of this section to be equipped with a bag leak 
detection system. You must meet the requirements specified in paragraph 
(b)(6)(i) of this section and either paragraph (b)(6)(ii) or (iii) of 
this section.
    (i) If it is not possible for you to take the corrective actions 
specified in paragraph (b)(3)(iii) or (iv) of this section for a process 
or fabric filter control device, you must keep at least one replacement 
primary fabric filter and one replacement secondary filter onsite at all 
times for that process or fabric filter control device. The 
characteristics of the replacement filters must be the same as the 
current fabric filters in use or have characteristics that would achieve 
equal or greater emission reductions.
    (ii) You must perform the pressure drop monitoring requirements in 
paragraph (b)(3) of this section. You may

[[Page 552]]

perform these requirements once per week rather than once or twice 
daily.
    (iii) You must perform the visible emissions observation 
requirements in paragraph (b)(4) of this section. You may perform these 
requirements once per week rather than once or twice daily.



Sec. 60.374a  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator must use as reference methods and procedures the test 
methods in appendix A to this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) After the initial performance test required in Sec. 60.8(a), 
you must conduct subsequent performance tests to demonstrate compliance 
with the lead and opacity standards in Sec. 60.372a. Performance 
testing must be conducted for each affected source subject to lead and 
opacity standards in Sec. 60.372a, that has not had a performance test 
within the last 5 years, except as described in paragraph (c) of this 
section. Thereafter, subsequent performance tests for each affected 
source must be completed no less frequently than every 5 years from the 
date the emissions source was last tested.
    (c) In lieu of conducting subsequent performance tests for each 
affected source, you may elect to group similar affected sources 
together and conduct subsequent performance tests on one representative 
affected source within each group of similar affected sources. The 
determination of whether affected sources are similar must meet the 
criteria in paragraph (c)(1) of this section. If you decide to test 
representative affected sources, you must prepare and submit a testing 
plan as described in paragraph (c)(3) of this section.
    (1) If you elect to test representative affected sources, the 
affected sources that are grouped together must be of the same process 
type (e.g., grid casting, paste mixing, three-process operations) and 
also have the same type of air pollution control device (e.g., fabric 
filters). You cannot group affected sources from different process types 
or with different air pollution control device types together for the 
purposes of this section.
    (2) The results of the performance test conducted for the affected 
source selected as representative of a group of similar affected sources 
will represent the results for each affected source within the group. In 
the performance test report, all affected sources in the group will need 
to be listed.
    (3) If you plan to conduct subsequent performance tests on 
representative emission units, you must submit a test plan. This test 
plan must be submitted to the Administrator or delegated authority for 
review and approval no later than 90 days prior to the first scheduled 
performance test. The test plan must contain the information specified 
in paragraphs (c)(3)(i) through (iii) of this section.
    (i) A list of all emission units. This list must clearly identify 
all emission units that have been grouped together as similar emission 
units. Within each group of emission units, you must identify the 
emission unit that will be the representative unit for that group and 
subject to performance testing.
    (ii) A list of the process type and type of air pollution control 
device on each emission unit.
    (iii) The date of last test for each emission unit and a schedule 
indicating when you will conduct performance tests for each emission 
unit within the representative groups.
    (4) If you conduct subsequent performance tests on representative 
emission units, the unit with the oldest test must be tested first, and 
each subsequent performance test must be performed for a different unit 
until all units in the group have been tested. The order of testing for 
each subsequent test must proceed such that the unit in the group with 
the least recent performance test is the next unit to be tested.
    (5) You may not conduct performance tests during periods of 
malfunction. You must record the process information that is necessary 
to document operating conditions during the test and include in such 
record an explanation to support that such conditions represent normal 
operation. You must make available to the Administrator in

[[Page 553]]

the test report, records as may be necessary to determine the conditions 
of performance tests.
    (d) The owner or operator must determine compliance with the lead 
and opacity standards in Sec. 60.372a, as follows:
    (1) EPA Method 12 or EPA Method 29 of appendix A to this part must 
be used to determine the lead concentration (CPb) and the volumetric 
flow rate (Qsda) of the effluent gas. The sampling time and sample 
volume for each run must be at least 60 minutes and 0.85 dscm (30 dscf).
    (2) EPA Method 9 of appendix A to this part and the procedures in 
Sec. 60.11 must be used to determine opacity during the performance 
test. For EPA Method 9, the opacity numbers must be rounded off to the 
nearest whole percentage. ASTM D7520-16 (incorporated by reference, see 
Sec. 60.17) is an acceptable alternative to EPA Method 9 with the 
specified conditions in paragraphs (d)(2)(i) through (v) of this 
section.
    (i) During the digital camera opacity technique (DCOT) certification 
procedure outlined in Section 9.2 of ASTM D7520-16, you or the DCOT 
vendor must present the plumes in front of various backgrounds of color 
and contrast representing conditions anticipated during field use such 
as blue sky, trees, and mixed backgrounds (clouds and/or a sparse tree 
stand).
    (ii) You must also have standard operating procedures in place 
including daily or other frequency quality checks to ensure the 
equipment is within manufacturing specifications as outlined in Section 
8.1 of ASTM D7520-16.
    (iii) You must follow the record keeping procedures outlined in 
Sec. 63.10(b)(1) for the DCOT certification, compliance report, data 
sheets, and all raw unaltered JPEGs used for opacity and certification 
determination.
    (iv) You or the DCOT vendor must have a minimum of four (4) 
independent technology users apply the software to determine the visible 
opacity of the 300 certification plumes. For each set of 25 plumes, the 
user may not exceed 15 percent opacity of any one reading and the 
average error must not exceed 7.5 percent opacity.
    (v) This approval does not provide or imply a certification or 
validation of any vendor's hardware or software. The onus to maintain 
and verify the certification and/or training of the DCOT camera, 
software and operator in accordance with ASTM D7520-16 and this letter 
is on the facility, DCOT operator, and DCOT vendor.
    (3) When different operations in a three-process operation facility 
are ducted to separate control devices, the lead emission concentration 
(C) from the facility must be determined using equation 1 to this 
paragraph (d)(3) as follows:
[GRAPHIC] [TIFF OMITTED] TR23FE23.001

Where:

C = concentration of lead emissions for the entire facility, mg/dscm 
          (gr/dscf).
Ca = concentration of lead emissions from facility ``a,'' mg/
          dscm (gr/dscf).
Qsda = volumetric flow rate of effluent gas from facility 
          ``a,'' dscm/hr (dscf/hr).
n = total number of control devices to which separate operations in the 
          facility are ducted.

    (4) The owner or operator of lead oxide manufacturing facility must 
determine compliance with the lead standard in Sec. 60.372a(a)(5) as 
follows:
    (i) The emission rate (E) from lead oxide manufacturing facility 
must be computed for each run using equation 2 to this paragraph 
(d)(4)(i) as follows:

[[Page 554]]

[GRAPHIC] [TIFF OMITTED] TR23FE23.002

Where:

E = emission rate of lead, mg/kg (lb/ton) of lead charged.
CPbi = concentration of lead from emission point ``i,'' mg/
          dscm (gr/dscf).
Qsdi = volumetric flow rate of effluent gas from emission 
          point ``i,'' dscm/hr (dscf/hr).
M = number of emission points in the affected facility.
P = lead feed rate to the facility, kg/hr (ton/hr).
K = conversion factor, 1.0 mg/mg (7000 gr/lb).

    (ii) The average lead feed rate (P) must be determined for each run 
using equation 3 to this paragraph (d)(4)(ii) as follows:
[GRAPHIC] [TIFF OMITTED] TR23FE23.003

Where:

N = number of lead ingots charged.
W = average mass of the lead ingots, kg (ton).
Q = duration of run, hr.



Sec. 60.375a  Recordkeeping and reporting requirements.

completing each performance test or demonstration of compliance required 
by this subpart, you must submit the results of the performance test 
following the procedures specified in paragraphs (b)(1) through (3) of 
this section.
    (1) Data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-
reporting-tool-ert) at the time of the test. Submit the results of the 
performance test to the EPA via the Compliance and Emissions Data 
Reporting Interface (CEDRI), which can be accessed through the EPA's 
Central Data Exchange (CDX) (https://cdx.epa.gov/). The data must be 
submitted in a file format generated using the EPA's ERT. Alternatively, 
you may submit an electronic file consistent with the extensible markup 
language (XML) schema listed on the EPA's ERT website.
    (2) Data collected using test methods that are not supported by the 
EPA's ERT as listed on the EPA's ERT website at the time of the test. 
The results of the performance test must be included as an attachment in 
the ERT or an alternate electronic file consistent with the XML schema 
listed on the EPA's ERT website. Submit the ERT generated package or 
alternative file to the EPA via CEDRI.
    (3) Data collected containing confidential business information 
(CBI). (i) The EPA will make all the information submitted through CEDRI 
available to the public without further notice to you. Do not use CEDRI 
to submit information you claim as CBI. Although we do not expect 
persons to assert a claim of CBI, if you wish to assert a CBI claim for 
some of the information submitted under paragraph (b)(1) or (2) of this 
section, you must submit a complete file, including information claimed 
to be CBI, to the EPA.
    (ii) The file must be generated using the EPA's ERT or an alternate 
electronic file consistent with the XML schema listed on the EPA's ERT 
website.
    (iii) Clearly mark the part or all of the information that you claim 
to be CBI. Information not marked as CBI may be authorized for public 
release without prior notice. Information marked as CBI will not be 
disclosed except in accordance with procedures set forth in 40 CFR part 
2.
    (iv) The preferred method for CBI submittal is for it to be 
transmitted electronically using email attachments, File Transfer 
Protocol (FTP), or other online file sharing services. Electronic 
submissions must be transmitted directly to the OAQPS CBI Office at the 
email address [email protected], and as described in this paragraph 
(b)(3), should include clear CBI markings and be flagged to the 
attention of the Group Leader, Measurement Policy Group. If assistance 
is needed with submitting large electronic files that exceed the file 
size limit for email attachments, and if you do not have your own file 
sharing service, please email [email protected] to request a file 
transfer link.
    (v) If you cannot transmit the file electronically, you may send CBI 
information through the postal service to the following address: OAQPS 
Document Control Officer (C404-02), U.S. Environmental Protection 
Agency, Research Triangle Park, North Carolina 27711, Attention: Lead 
Acid Battery Sector Lead and Group Leader, Measurement Policy Group. The 
mailed CBI material should be double wrapped and clearly marked. Any CBI 
markings should not show through the outer wrapping.
    (vi) All CBI claims must be asserted at the time of submission. 
Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, 
under CAA section 114(c), emissions data is not entitled to confidential 
treatment, and the EPA is required to make emissions data available to 
the public. Thus, emissions data will not be protected as CBI and will 
be made publicly available.
    (vii) You must submit the same file submitted to the CBI office with 
the CBI omitted to the EPA via the EPA's CDX as described in paragraphs 
(a)(1) and (2) of this section.
    (c) You must submit a report of excess emissions and monitoring 
systems

[[Page 556]]

performance report and summary report according to Sec. 60.7(c) and (d) 
to the Administrator semiannually. Report the number of failures to meet 
an applicable standard in this part. For each instance, report the date, 
time, cause, and duration of each failure. For each failure, the report 
must include a list of the affected sources or equipment, an estimate of 
the quantity of each regulated pollutant emitted over any emission 
limit, and a description of the method used to estimate the emissions. 
You must use the appropriate spreadsheet template on the CEDRI website 
(https://www.epa.gov/electronic-reporting-air-emissions/cedri) for this 
subpart. The date report templates become available will be listed on 
the CEDRI website. The report must be submitted by the deadline 
specified in this subpart, regardless of the method in which the report 
is submitted. Submit all reports to the EPA via CEDRI, which can be 
accessed through the EPA's CDX (https://cdx.epa.gov/). The EPA will make 
all the information submitted through CEDRI available to the public 
without further notice to you. As stated in paragraph (b)(3) of this 
section, do not use CEDRI to submit information you claim as CBI. 
Anything submitted using CEDRI cannot later be claimed CBI. If you claim 
CBI, submit the report following description in paragraph (b)(3) of this 
section. The same file with the CBI omitted must be submitted to CEDRI 
as described in this section.
    (d) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for 
failure to timely comply with that reporting requirement. To assert a 
claim of EPA system outage, you must meet the requirements outlined in 
paragraphs (d)(1) through (7) of this section.
    (1) You must have been or will be precluded from accessing CEDRI and 
submitting a required report within the time prescribed due to an outage 
of either the EPA's CEDRI or CDX systems.

soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (5) You must provide to the Administrator a written description 
identifying:
    (i) The date(s) and time(s) when CDX or CEDRI was accessed and the 
system was unavailable;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (iii) A description of measures taken or to be taken to minimize the 
delay in reporting; and
    (iv) The date by which you propose to report, or if you have already 
met the reporting requirement at the time of the notification, the date 
you reported.
    (6) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (7) In any circumstance, the report must be submitted electronically 
as soon as possible after the outage is resolved.
    (e) If you are required to electronically submit a report through

delay in reporting.
    (3) You must provide to the Administrator:
    (i) A written description of the force majeure event;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;
    (iii) A description of measures taken or to be taken to minimize the 
delay in reporting; and
    (iv) The date by which you propose to report, or if you have already 
met the reporting requirement at the time of the notification, the date 
you reported.
    (4) The decision to accept the claim of force majeure and allow an 
extension to the reporting deadline is solely within the discretion of 
the Administrator.
    (5) In any circumstance, the reporting must occur as soon as 
possible after the force majeure event occurs.
    (f) Any records required to be maintained by this subpart that are 
submitted electronically via the EPA's CEDRI may be maintained in 
electronic format. This ability to maintain electronic copies does not 
affect the requirement for facilities to make records, data, and reports 
available upon request to a delegated air agency or the EPA as part of 
an on-site compliance evaluation.

into purified metals (or other products), or up to and including all 
material transfer and storage operations that precede the operations 
that produce refined metals (or other products) from metallic mineral 
concentrates at facilities adjacent to the metallic mineral processing 
plant. This definition shall not be construed as requiring that mining 
of ore be conducted in order for the combination of equipment to be 
considered a metallic mineral processing plant. (See also the definition 
of metallic mineral concentrate.)

Sec. 60.386  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine complance with the 
particulate matter standards Sec. 60.382 as follows:
    (1) Method 5 or 17 shall be used to determine the particulate matter 
concentration. The sample volume for each run shall be at least 1.70 
dscm (60 dscf). The sampling probe and filter holder of Method 5 may be 
operated without heaters if the gas stream being sampled is at ambient 
temperature. For gas streams above ambient temperature, the Method 5 
sampling train shall be operated with a probe and filter temperature 
slightly above the effluent temperature (up to a maximum filter 
temperature of 121 [deg]C (250 [deg]F)) in order to prevent water 
condensation on the filter.
    (2) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity from stack emissions and process fugitive emissions. 
The observer shall read opacity only when emissions are clearly 
identified as emanating solely from the affected facility being 
observed. A single visible emission observer may conduct visible 
emission observations for up to three fugitive, stack, or vent emission 
points within a 15-second interval. This option is subject to the 
following limitations:
    (i) No more than three emission points are read concurrently;
    (ii) All three emission points must be within a 70[deg] viewing 
sector or angle in front of the observer such that the proper sun 
position can be maintained for all three points; and
    (iii) If an opacity reading for any one of the three emission points 
is within 5 percent opacity of the application standard, then the 
observer must stop taking readings for the other two points and continue 
reading just that single point.
    (c) To comply with Sec. 60.385(c), the owner or operator shall use 
the monitoring devices in Sec. 60.384(a) and (b) to determine the 
pressure loss of the gas stream through the scrubber and scrubbing 
liquid flow rate at any time during each particulate matter run, and the 
average of the three determinations shall be computed.

Sec. 60.393  Performance test and compliance provisions.

    (a) Section 60.8 (d) and (f) do not apply to the performance test 
procedures required by this section.
    (b) The owner or operator of an affected facility shall conduct an 
initial performance test in accordance with Sec. 60.8(a) and thereafter 
for each calendar month for each affected facility according to the 
procedures in this section.
    (c) The owner or operator shall use the following procedures for 
determining the monthly volume weighted average mass of VOC emitted per 
volume of applied coating solids.
    (1) The owner or operator shall use the following procedures for 
each affected facility which does not use a capture system and a control 
device to comply with the applicable emission limit specified under 
Sec. 60.392.
    (i) Calculate the volume weighted average mass of VOC per volume of 
applied coating solids for each calendar month for each affected 
facility. The owner or operator shall determine the composition of the 
coatings by formulation data supplied by the manufacturer of the coating 
or from data determined by an analysis of each coating, as received, by 
Method 24. The Administrator may require the owner or operator who uses 
formulation data supplied by the manufacturer of the coating to 
determine data used in the calculation of the VOC content of coatings by 
Method 24 or an equivalent or alternative method. The owner or operator 
shall determine from company records on a monthly basis the volume of 
coating consumed, as received, and the mass of solvent used for thinning 
purposes. The volume weighted average of the total mass of VOC per 
volume of coating solids used each calendar month will be determined by 
the following procedures.
    (A) Calculate the mass of VOC used in each calendar month for each 
affected facility by the following equation where ``n'' is the total 
number of coatings used and ``m'' is the total number of VOC solvents 
used:
[GRAPHIC] [TIFF OMITTED] TC16NO91.027

[[Sigma]LdjDdj will be zero if no VOC 
          solvent is added to the coatings, as received].

    (B) Calculate the total volume of coating solids used in each 
calendar month for each affected facility by the following equation 
where ``n'' is the total number of coatings used:
[GRAPHIC] [TIFF OMITTED] TC16NO91.028

    (C) Select the appropriate transfer efficiency (T) from the 
following tables for each surface coating operation:

------------------------------------------------------------------------
                                                               Transfer
                     Application method                       efficiency
------------------------------------------------------------------------
Air Atomized Spray (waterborne coating).....................        0.39
Air Atomized Spray (solvent-borne coating)..................        0.50
Manual Electrostatic Spray..................................        0.75
Automatic Electrostatic Spray...............................        0.95
Electrodeposition...........................................        1.00
------------------------------------------------------------------------


The values in the table above represent an overall system efficiency 
which includes a total capture of purge. If a spray system uses line 
purging after each vehicle and does not collect any of the purge 
material, the following table shall be used:

------------------------------------------------------------------------
                                                               Transfer
                     Application method                       efficiency
------------------------------------------------------------------------
Air Atomized Spray (waterborne coating).....................        0.30
Air Atomized Spray (solvent-borne coating)..................        0.40
Manual Electrostatic Spray..................................        0.62
Automatic Electrostatic Spray...............................        0.75
------------------------------------------------------------------------


If the owner or operator can justify to the Administrator's satisfaction 
that other values for transfer efficiencies are appropriate, the 
Administrator will approve their use on a case-by-case basis.
    (1) When more than one application method (l) is used on an 
individual surface coating operation, the owner or operator shall 
perform an analysis to determine an average transfer efficiency by the 
following equation where ``n'' is the total number of coatings used and 
``p'' is the total number of application methods:

[[Page 564]]

[GRAPHIC] [TIFF OMITTED] TC16NO91.029

    (D) Calculate the volume weighted average mass of VOC per volume of 
applied coating solids (G) during each calendar month for each affected 
facility by the following equation:

    (E) For each EDP prime coat operation, calculate the turnover ratio 
(RT) by the following equation:
[GRAPHIC] [TIFF OMITTED] TR11OC94.000


Then calculate or select the appropriate limit according to Sec. 
60.392(a).
    (ii) If the volume weighted average mass of VOC per volume of 
applied coating solids (G), calculated on a calendar month basis, is 
less than or equal to the applicable emission limit specified in Sec. 
60.392, the affected facility is in compliance. Each monthly calculation 
is a performance test for the purpose of this subpart.
    (2) The owner or operator shall use the following procedures for 
each affected facility which uses a capture system and a control device 
that destroys VOC (e.g., incinerator) to comply with the applicable 
emission limit specified under Sec. 60.392.
    (i) Calculate the volume weighted average mass of VOC per volume of 
applied coating solids (G) during each calendar month for each affected 
facility as described under Sec. 60.393(c)(1)(i).

applied solids emitted after the control device, by the following 
equation: N = G[1-FE]
    (A) Determine the fraction of total VOC which is emitted by an 
affected facility that enters the control device by using the following 
equation where ``n'' is the total number of stacks entering the control 
device and ``p'' is the total number of stacks not connected to the 
control device:
[GRAPHIC] [TIFF OMITTED] TR09MY23.000

    (1) In subsequent months, the owner or operator shall use the most 
recently determined capture fraction for the performance test.
    (2) If the owner can justify to the Administrator's satisfaction 
that another method will give comparable results, the Administrator will 
approve its use on a case-by-case basis.
    (B) Determines the destruction efficiency of the control device 
using values of the volumetric flow rate of the gas streams and the VOC 
content (as carbon) of each of the gas streams in and out of the device 
by the following equation where ``n'' is the total number of stacks 
entering the control device and ``m'' is the total number of stacks 
leaving the control device:
[GRAPHIC] [TIFF OMITTED] TC01JN92.014

    (1) In subsequent months, the owner or operator shall use the most 
recently

[[Page 565]]

determined VOC destruction efficiency for the performance test.
    (C) If an emission control device controls the emissions from more 
than one affected facility, the owner or operator shall measure the VOC 
concentration (Cbi) in the effluent gas entering the control 
device (in parts per million by volume) and the volumetric flow rate 
(Qbi) of the effluent gas (in dry standard cubic meters per 
hour) entering the device through each stack. The destruction or removal 
efficiency determined using these data shall be applied to each affected 
facility served by the control device.
    (iii) If the volume weighted average mass of VOC per volume of 
applied solids emitted after the control device (N) calculated on a 
calendar month basis is less than or equal to the applicable emission 
limit specified in Sec. 60.392, the affected facility is in compliance. 
Each monthly calculation is a performance test for the purposes of this 
subpart.
    (3) The owner or operator shall use the following procedures for 
each affected facility which uses a capture system and a control device 
that recovers the VOC (e.g., carbon adsorber) to comply with the 
applicable emission limit specified under Sec. 60.392.
    (i) Calculate the mass of VOC (Mo + Md) used 
during each calendar month for each affected facility as described under 
Sec. 60.393(c)(1)(i).
    (ii) Calculate the total volume of coating solids (Ls) 
used in each calendar month for each affected facility as described 
under Sec. 60.393(c)(1)(i).
    (iii) Calculate the mass of VOC recovered (Mr) each 
calendar month for each affected facility by the following equation:

    (iv) Calculate the volume weighted average mass of VOC per volume of 
applied coating solids emitted after the control device during a 
calendar month by the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.031

    (v) If the volume weighted average mass of VOC per volume of applied 
solids emitted after the control device (N) calculated on a calendar 
month basis is less than or equal to the applicable emission limit 
specified in Sec. 60.392, the affected facility is in compliance. Each 
monthly calculation is a performance test for the purposes of this 
subpart.

Administrator every calendar quarter of each instance in which the 
volume-weighted average of the total mass of VOC's emitted to the 
atmosphere per volume of applied coating solids (N) is greater than the 
limit specified under Sec. 60.392. If no such instances have occurred 
during a particular quarter, a report stating this shall be submitted to 
the Administrator semiannually. Where compliance is achieved through the 
use of a capture system and control device, the volume-weighted average 
after the control device should be reported.
    (c) Where compliance with Sec. 60.392 is achieved through the use 
of incineration, the owner or operator shall continuously record the

[deg]C less than the average temperature immediately before the catalyst 
bed during the most recent control device performance test at which 
destruction efficiency was determined as specified under Sec. 60.393. 
In addition, every three-hour period shall be reported each quarter 
during which the average temperature difference across the catalyst bed 
when the coating system is operational is less than 80 percent of the 
average temperature difference of the device during the most recent 
control device performance test at which destruction efficiency was

advance of any test by Method 25.
    (e) The owner or operator shall submit the reports listed in 
paragraphs (b) and (c) of this section following the procedures 
specified in paragraphs (e)(1) through (3) of this section. In addition 
to the information required in paragraphs (b) and (c) of this section, 
owners or operators are required to report excess emissions and a 
monitoring systems performance report and a summary report to the 
Administrator according to Sec. 60.7(c) and (d). Owners or operators 
are required by Sec. 60.7(c) and (d) to report the date, time, cause, 
and duration of each exceedance of the applicable emission limit 
specified in Sec. 60.392, any malfunction of the air pollution control 
equipment, and any periods during which the CMS or monitoring device is 
inoperative. For each failure, the report must include a list of the 
affected sources or equipment and a description of the method used to 
estimate the emissions.
    (1) Effective date. On and after November 6, 2023, or once the 
reporting template has been available on the CEDRI website for 1-year, 
whichever date is later, owners or operators must use the appropriate 
spreadsheet template on the Compliance and Emissions Data Reporting 
Interface (CEDRI) website (https://www.epa.gov/electronic-reporting-air-
emissions/cedri) for this subpart. The date the reporting template for 
this subpart becomes available will be listed on the CEDRI website. The 
report must be submitted by the deadline specified in this subpart, 
regardless of

[[Page 567]]

the method by which the report is submitted. Submit all reports to the 
EPA via CEDRI, which can be accessed through the EPA's CDX (https://
cdx.epa.gov/). The EPA will make all the information submitted through 
CEDRI available to the public without further notice to the owner or 
operator. Do not use CEDRI to submit information you claim as CBI. Any 
information submitted using CEDRI cannot later be claimed CBI. If you 
claim CBI, submit the report following the procedure described in 
paragraph (f)(3) of this section. The same file with the CBI omitted 
must be submitted to CEDRI as described in paragraph (f)(3) of this 
section.
    (2) System outage. Owner or operators that are required to submit a 
report electronically through CEDRI in the EPA's CDX, may assert a claim 
of EPA system outage for failure to timely comply with that reporting 
requirement. To assert a claim of EPA system outage, owners or operators 
must meet the requirements outlined in paragraphs (e)(2)(i) through 
(vii) of this section.
    (i) You must have been or will be precluded from accessing CEDRI and 
submitting a required report within the time prescribed due to an outage 
of either the EPA's CEDRI or CDX systems.
    (ii) The outage must have occurred within the period of time 
beginning five business days prior to the date that the submission is 
due.

soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (v) You must provide to the Administrator a written description 
identifying:
    (A) The date(s) and time(s) when CDX or CEDRI was accessed, and the 
system was unavailable;
    (B) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (C) A description of measures taken or to be taken to minimize the 
delay in reporting; and
    (D) The date by which you propose to report, or if you have already 
met the reporting requirement at the time of the notification, the date 
you reported.
    (vi) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (vii) In any circumstance, the report must be submitted 
electronically as soon as possible after the outage is resolved.
    (3) Force majeure. Owner or operators that are required to submit a 
report electronically through CEDRI in the EPA's CDX, may assert a claim 
of force majeure for failure to timely comply with that reporting 
requirement. To assert a claim of force majeure, Owner or operators must 
meet the requirements outlined in paragraphs (e)(1) through (5) of this 
section.
    (i) You may submit a claim if a force majeure event is about to 
occur, occurs, or has occurred or there are lingering effects from such 
an event within the period of time beginning five business days prior to 
the date the submission is due. For the purposes of this section, a 
force majeure event is defined as an event that will be or has been 
caused by circumstances beyond the control of the affected facility, its 
contractors, or any entity controlled by the affected facility that 
prevents you from complying with the requirement to submit a report 
electronically within the time period prescribed. Examples of such 
events are acts of nature (e.g., hurricanes, earthquakes, or floods), 
acts of war or terrorism, or equipment failure or safety hazard beyond 
the control of the affected facility (e.g., large scale power outage).
    (ii) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (iii) You must provide to the Administrator:
    (A) A written description of the force majeure event;
    (B) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;

[[Page 568]]

    (C) A description of measures taken or to be taken to minimize the 
delay in reporting; and
    (D) The date by which you propose to report, or if you have already 
met the reporting requirement at the time of the notification, the date 
you reported.
    (iv) The decision to accept the claim of force majeure and allow an 
extension to the reporting deadline is solely within the discretion of 
the Administrator.
    (f) Where compliance is achieved through the use of incineration, 
the owner or operator shall submit control device performance test 
results at which destruction efficiency is determined for initial and 
subsequent performance tests according to paragraph (a) of this section 
within 60 days of completing each performance test following the 
procedures specified in paragraphs (f)(1) through (3) of this section.
    (1) Data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-
reporting-tool-ert) at the time of the test.
    (i) Submit the results of the performance test to the EPA via the 
CEDRI, which can be accessed through the EPA's Central Data Exchange 
(CDX) (https://cdx.epa.gov/).
    (ii) The data must be submitted in a file format generated using the 
EPA's ERT. Alternatively, the owner or operator may submit an electronic 
file consistent with the extensible markup language (XML) schema listed 
on the EPA's ERT website.
    (2) Data collected using test methods that are not supported by the 
EPA's ERT as listed on the EPA's ERT website at the time of the test.
    (i) The results of the performance test must be included as an 
attachment in the ERT or an alternate electronic file consistent with 
the XML schema listed on the EPA's ERT website.
    (ii) Submit the ERT generated package or alternative file to the EPA 
via CEDRI.
    (3) Confidential business information (CBI). Do not use CEDRI to 
submit information you claim as CBI. Any information submitted using 
CEDRI cannot later be claimed CBI. Under CAA section 114(c), emissions 
data is not entitled to confidential treatment, and the EPA is required 
to make emissions data available to the public. Thus, emissions data 
will not be protected as CBI and will be made publicly available. Owners 
or operators that assert a CBI claim for any information submitted under 
paragraph (f)(1) or (2) of this section, must submit a complete file, 
including information claimed to be CBI, to the EPA. The file must be 
generated using the EPA's ERT or an alternate electronic file consistent 
with the XML schema listed on the EPA's ERT website. Owners or operators 
can submit CBI according to one of the two procedures in paragraph 
(f)(3)(i) or (ii) of this section. All CBI claims must be asserted at 
the time of submission.
    (i) If sending CBI through the postal service, submit the file on a 
compact disc, flash drive, or other commonly used electronic storage 
medium and clearly mark the medium as CBI. Owners or operators are 
required to mail the electronic medium to U.S. EPA/OAQPS/CORE CBI 
Office, Attention: Automobile and Light Duty Truck Surface Coating 
Operations Sector Lead, MD C404-02, 4930 Old Page Rd., Durham, NC 27703. 
The same file with the CBI omitted must be submitted to the EPA via the 
EPA's CDX as described in paragraphs (f)(1) and (2) of this section.
    (ii) The EPA preferred method for CBI submittal is for it to be 
transmitted electronically using email attachments, File Transfer 
Protocol (FTP), or other online file sharing services (e.g., Dropbox, 
OneDrive, Google Drive). Electronic submissions must be transmitted 
directly to the OAQPS CBI Office at the email address [email protected], 
Attention: Automobile and Light Duty Truck Surface Coating Operations 
Sector Lead, and as described above, should be clearly identified as 
CBI. If assistance is needed with submitting large electronic files that 
exceed the file size limit for email attachments, and if you do not have 
your own file sharing service, you may

Sec. 60.396  Reference methods and procedures.

    (a) The reference methods in appendix A to this part, except as 
provided in Sec. 60.8 shall be used to conduct performance tests.
    (1) Method 24 or an equivalent or alternative method approved by the 
Administrator shall be used for the determination of the data used in 
the calculation of the VOC content of the coatings used for each 
affected facility. Manufacturers' formulation data is approved by the 
Administrator as an alternative method to Method 24. In the event of 
dispute, Method 24 shall be the referee method.
    (2) Method 25 or an equivalent or alternative method approved by the 
Administrator shall be used for the determination of the VOC 
concentration in the effluent gas entering and leaving the emission 
control device for each stack equipped with an emission control device 
and in the effluent gas leaving each stack not equipped with a control 
device.
    (3) The following methods shall be used to determine the volumetric 
flow rate in the effluent gas in a stack:
    (i) Method 1 for sample and velocity traverses,
    (ii) Method 2 for velocity and volumetric flow rate,
    (iii) Method 3 for gas analysis, and
    (iv) Method 4 for stack gas moisture.
    (b) For Method 24, the coating sample must be a 1-liter sample taken 
in a 1-liter container.
    (c) For Method 25, the sampling time for each of three runs must be 
at least one hour. The minimum sample volume must be 0.003 dscm except 
that shorter sampling times or smaller volumes, when necessitated by 
process variables or other factors, may be approved by the 
Administrator. The Administrator will approve the sampling of 
representative stacks on a case-by-case basis if the owner or operator 
can demonstrate to the satisfaction of the Administrator that the 
testing of representative stacks would yield results comparable to those 
that would be obtained by testing all stacks.

Sec. 60.393a  Performance test and compliance provisions.

    (a) Representative conditions. You must conduct performance tests 
under representative conditions for the affected coating operation 
according to Sec. 60.8(c) and under the conditions in this section 
unless you obtain a waiver of the performance test according to the 
provisions in Sec. 60.8(b)(4).
    (1) Operations during periods of startup, shutdown, or nonoperation 
do not constitute conditions representative of normal operation for 
purposes of conducting a performance test. You may not conduct 
performance tests during periods of malfunction. Emissions in excess of 
the applicable emission limit during periods of startup, shutdown, and 
malfunction will be considered a violation of the applicable emission 
limit.
    (2) You must record the process information that is necessary to 
document operating conditions during the performance test and explain 
why the conditions represent normal operation. Upon request, you must 
make available to the Administrator such records as may be necessary to 
determine the conditions of performance tests.
    (3) Section 60.8(d) and (f) do not apply to the performance test 
procedures required by this section.
    (b) Initial and continuous compliance requirements. You must conduct 
an initial performance test in accordance with Sec. 60.8(a) and 
thereafter for each calendar month for each affected facility according 
to the procedures in this section. You must also conduct periodic 
performance tests of add-on controls, except for solvent recovery 
systems for which liquid-liquid material balances are conducted 
according to paragraph (l) of this section, to reestablish the operating 
limits required by Sec. 60.392a within 5 years following the previous 
performance test. You must meet all the requirements of this section to 
demonstrate initial and continuous compliance.
    (1) To demonstrate initial compliance, the VOC emissions from 
affected source must meet the applicable emission limitation in Sec. 
60.392a and the work practice standards in Sec. 60.392a and the 
applicable operating limits in Sec. 60.392a established during the 
initial performance test using the procedures in Sec. 60.394a and table 
1 to this subpart.
    (i) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of this section. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 60.8 and ends on the last day of the month following 
the compliance date. If the compliance date occurs on any day other than 
the first day of a

[[Page 581]]

month, then the initial compliance period extends through the end of 
that month plus the next month.
    (ii) You must determine the mass of VOC emissions and volume of 
coating solids deposited in the initial compliance period. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 60.396a and 60.397a; supporting documentation showing that 
during the initial compliance period the VOC emission rate was equal to 
or less than the emission limit in Sec. 60.392a; the operating limits 
established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 60.394a; and 
documentation of whether you developed and implemented the work practice 
plans required by Sec. 60.392(b) and (c).
    (2) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 60.392a, the VOC emission rate for each 
compliance period, determined according to the procedures in this 
section, must be equal to or less than the applicable emission limit in 
Sec. 60.392a. A compliance period consists of 1 month. Each month after 
the end of the initial compliance period described in Sec. 
60.393a(b)(1)(i) is a compliance period consisting of that month. You 
must perform the calculations in this section on a monthly basis.
    (3) If the VOC emission rate for any 1-month compliance period 
exceeded the applicable emission limit in Sec. 60.392a, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Sec. 60.395a(h).
    (c) Compliance with operating limits. Except as provided in 
paragraph (c)(1) of this section, you must establish and demonstrate 
continuous compliance during the initial compliance period with the 
operating limits required by Sec. 60.392a, using the procedures 
specified in Sec. 60.394a.
    (1) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by Sec. 
60.394a until after you have completed the initial performance test 
specified in paragraph (b) of this section. During the period between 
the startup date of the affected source and the initial performance test 
required by Sec. 60.8 you must maintain a log detailing the operation 
and maintenance of the emission capture system, the add-on control 
device, and the continuous monitoring system (CMS).
    (2) You must demonstrate continuous compliance with each operating 
limit required by Sec. 60.392a that applies to you, as specified in 
Table 1 to this subpart, and you must conduct performance tests as 
specified in paragraph (c)(4) of this section.
    (3) If an operating parameter is out of the allowed range specified 
in table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. 60.395a(h).
    (4) If an operating parameter deviates from the operating limit 
specified in table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation except as provided in 
Sec. 60.393a (m).
    (5) Except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to paragraph (l) of this 
section for controlled coating operations, you must conduct periodic 
performance tests of add-on controls and reestablish the operating 
limits required by Sec. 60.392a within 5 years following the previous 
performance test. You must conduct the first periodic performance test 
within 5 years following the initial performance test required by Sec. 
60.8. Thereafter, you must conduct a performance test no later than 5 
years following the previous performance test. Operating limits must be 
confirmed or reestablished during each performance test. If you are 
using the alternative monitoring option for a catalytic oxidizer 
according to Sec. 60.394a(b)(3) and following the catalyst maintenance 
procedures in Sec. 60.394a(b)(4), you are not required to conduct 
periodic control device performance testing as specified by this 
paragraph (c). For any control device for which instruments are used to 
continuously measure organic compound emissions, you are not required to 
conduct periodic control device performance testing as specified by this

[[Page 582]]

paragraph. The requirements of this paragraph do not apply to measuring 
emission capture system efficiency.
    (6) You must meet the requirements for bypass lines in Sec. 
60.394a(h) for control devices other than solvent recovery systems for 
which you conduct liquid-liquid material balances. If any bypass line is 
opened and emissions are diverted to the atmosphere when the coating 
operation is running, this is a deviation that must be reported as 
specified in Sec. 60.395a(h). For the purposes of completing the 
compliance calculations specified in paragraph (j) of this section, you 
must assume that the emission capture system and add-on control device 
were achieving zero efficiency during the time period of the deviation.
    (d) Compliance with work practice requirements. You must develop, 
implement, and document implementation of the work practice plans 
required by Sec. 60.392a(b) and (c) during the initial compliance 
period, as specified in Sec. 60.395a.
    (1) You must demonstrate continuous compliance with the work 
practice standards in Sec. 60.392a (b) and (c). If you did not develop 
a work practice plan, if you did not implement the plan, or if you did 
not keep the records required by Sec. 60.395a (k)(11), this is a 
deviation from the work practice standards that must be reported as 
specified in Sec. 60.395a (k)(4).
    (2) [Reserved]
    (e) Compliance with emission limits. You must use the following 
procedures in paragraphs (f) through (m) of this section to determine 
the monthly volume weighted average mass of VOC emitted per volume of 
applied coating solids for each affected facility to demonstrate 
compliance with the applicable emission limitation in Sec. 60.392a. You 
may also use the guidelines presented in ``Protocol for Determining the 
Daily Volatile Organic Compound Emission Rate of Automobile and Light-
Duty Truck Primer-Surfacer and Topcoat'' EPA-453/R-08-002 (incorporated 
by reference, see Sec. 60.17) in making this demonstration.
    (f) Determine the mass fraction of VOC, density, and volume for each 
material used. You must follow the procedures specified in paragraphs 
(f)(1) through (3) of this section to determine the mass fraction of 
VOC, the density, and volume for each coating and thinner used during 
each month. For the electrodeposition primer operation, the mass 
fraction of VOC, density, and volume used must be determined for each 
material added to the tank or system during each month.
    (1) Determine the mass fraction of VOC for each material used. You 
must determine the mass fraction of VOC for each material used during 
the compliance period by using one of the options in paragraphs 
(f)(1)(i) through (iii) of this section.
    (i) EPA Method 24 (appendix A-7 to 40 CFR part 60). For coatings, 
you may use EPA Method 24 to determine the mass fraction of nonaqueous 
volatile matter and use that value as a substitute for the mass fraction 
of VOC. As an alternative to using EPA Method 24, you may use ASTM 
D2369-20 (incorporated by reference, see Sec. 60.17). For Method 24, 
the coating sample must be a 1-liter sample taken in a 1-liter 
container.
    (ii) Alternative method. You may use an alternative test method for 
determining the mass fraction of VOC once the Administrator has approved 
it. You must follow the procedure in Sec. 60.8(b)(3) to submit an 
alternative test method for approval.
    (iii) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (f)(1)(i) through (iii) of this section, 
such as manufacturer's formulation data. If there is a disagreement 
between such information and results of a test conducted according to 
paragraphs (f)(1)(i) through (iii) of this section, then the test method 
results will take precedence, unless after consultation, you demonstrate 
to the satisfaction of the enforcement authority that the facility's 
data are correct.
    (2) Determine the density of each material used. Determine the 
density of each material used during the compliance period from test 
results using ASTM D1475-13 (incorporated by reference, see Sec. 60.17) 
or for powder coatings, test method A or test method B of ASTM

[[Page 583]]

D5965-02 (Reapproved 2013) (incorporated by reference, see Sec. 60.17), 
or information from the supplier or manufacturer of the material. If 
there is disagreement between ASTM D1475-13 test results or ASTM D5965-
02 (Reapproved 2013), Test Method A or Test Method B test results and 
the supplier's or manufacturer's information, the test results will take 
precedence unless after consultation, the facility demonstrates to the 
satisfaction of the enforcement authority that the supplier's or 
manufacturer's data are correct.
    (3) Determine the volume of each material used. You must determine 
from company records on a monthly basis the volume of coating consumed, 
as received, and the mass of solvent used for thinning purposes.
    (g) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids for 
each coating used during the compliance period by a test or by 
information provided by the supplier or the manufacturer of the 
material, as specified in paragraphs (g)(1) and (2) of this section. For 
electrodeposition primer operations, the volume fraction of solids must 
be determined for each material added to the tank or system during each 
month. If test results obtained according to paragraph (g)(1) of this 
section do not agree with the information obtained under paragraph 
(g)(2) of this section, the test results will take precedence unless, 
after consultation, the facility demonstrates to the satisfaction of the 
enforcement authority that the facility's data are correct.
    (1) ASTM Method D2697-22 or ASTM Method D6093-97. You may use ASTM 
D2697-22 (incorporated by reference, see Sec. 60.17), or ASTM D6093-97 
(incorporated by reference, see Sec. 60.17), to determine the volume 
fraction of coating solids for each coating. Divide the nonvolatile 
volume percent obtained with the methods by 100 to calculate volume 
fraction of coating solids.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (h) Determine the transfer efficiency for each coating. You must 
determine the transfer efficiency for each non-electrodeposition prime 
coat coating, each guide coat coating and each topcoat coating using 
ASTM Method D5066-91 (Reapproved 2017), ``Standard Test Method for 
Determination of the Transfer Efficiency Under Production Conditions for 
Spray Application of Automotive Paints--Weight Basis'' (incorporated by 
reference, see Sec. 60.17), or the guidelines presented in ``Protocol 
for Determining the Daily Volatile Organic Compound Emission Rate of 
Automobile and Light-Duty Truck Primer-Surfacer and Topcoat'' EPA-453/R-
08-002 (incorporated by reference, see Sec. 60.17). You may conduct 
transfer efficiency testing on representative coatings and for 
representative spray booths as described in ``Protocol for Determining 
the Daily Volatile Organic Compound Emission Rate of Automobile and 
Light-Duty Truck Primer-Surfacer and Topcoat'' EPA-453/R-08-002 
(incorporated by reference, see Sec. 60.17). You may assume 100 percent 
transfer efficiency for electrodeposition primer coatings.

volume weighted average mass of VOC per volume of applied coating solids 
(G), calculated on a calendar month basis, is less than or equal to the 
applicable emission limit specified in Sec. 60.392a, the affected 
facility is in compliance. Each monthly calculation is a performance 
test for the purpose of this subpart.
    (j) Calculate the volume weighted average mass of VOC emitted per 
volume of applied coating solids after add-on controls. You use the 
following procedures for each affected facility which uses a capture 
system and a control device that destroys VOC (e.g., incinerator) to 
comply with the applicable emission limit specified under Sec. 60.392a. 
Use the procedures in paragraph (j)(1) through (5) of this section to 
calculate volume weighted average mass of VOC per volume of applied 
coating solids for each controlled coating operation using an emission 
capture system and add-on control device other than a solvent recovery 
system for which you conduct liquid-liquid material balances. For each 
controlled coating operation using a solvent recovery system for which 
you conduct a liquid-liquid material balance, you must use the 
procedures in paragraph (l) of this section.
    (1) Calculate the volume weighted average mass of VOC per volume of 
applied coating solids (G) during each calendar month for each affected 
facility as described under Sec. 60.393a(i)(4).
    (2) Calculate the volume weighted average mass of VOC per volume of

    (ii) If two or more add-on control devices are used for the same 
emission stream, you must measure emissions at the outlet of each device 
in accordance with Sec. 60.396a(c). If there is more than one inlet or 
outlet to the add-on control device, you must calculate the total 
gaseous organic mass flow rate for each inlet and each outlet and then 
total all of the inlet emissions and total all of the outlet emissions 
in accordance with Sec. 60.396a(d). The emission destruction or removal 
efficiency of the add-on control device is the average of the 
efficiencies determined in the three test runs. The destruction or 
removal efficiency determined using these data shall be applied to each 
affected facility served by the control device.
    (5) Calculate the mass of VOC for each affected facility each 
calendar month for each period of time in which a deviation, including a 
deviation during a period of startup, shutdown, or malfunction, from an 
emission limitation, an operating limit or any CMS requirement for the 
capture system or control device serving the controlled coating 
operation occurred. Except as provided in paragraph (m) of this section, 
for any period of time in which a deviation, including a deviation 
during a period of startup, shutdown, or malfunction, from an emission 
limitation or operating limit or from any CMS requirement of the capture 
system or control device serving the controlled coating operation 
occurred, you must assume zero efficiency for the emission capture 
system and add-on control device. During such a deviation you must 
assume the affected source was uncontrolled for the duration of the 
deviation using the equation in paragraph (i)(4) of this section.
    (6) Adjust the volume weighted average mass of VOC per volume of 
applied coating solids emitted after the control device for each 
affected facility (N) during a calendar month for periods of deviation 
by adding the mass of VOC for the uncontrolled period of time according 
to paragraph (i)(5) of this section.

of applied solids emitted after the control device (N) calculated on a 
calendar month basis is less than or equal to the applicable emission 
limit specified in Sec. 60.392a, the affected facility is in 
compliance. Each monthly calculation is a performance test for the 
purposes of this subpart.
    (k) Calculate the volume weighted average mass of VOC emitted per 
volume of applied coating solids after add-on recovery devices. You must 
use the following procedures for each affected facility which uses a 
capture system and a control device that recovers the VOC (e.g., carbon 
adsorber) other than a solvent recovery system for which you conduct a 
liquid-liquid material balance to comply with the applicable emission 
limit specified under Sec. 60.392a.

applied coating solids emitted after the recovery device for each 
affected facility (N) during a calendar month for periods of deviation 
by adding the mass of VOC for the uncontrolled periods of time according 
to paragraph (i)(6) of this section.
    (6) If the adjusted volume weighted average mass of VOC per volume 
of applied solids emitted after the control device (N) calculated on a 
calendar month basis is less than or equal to the applicable emission 
limit specified in Sec. 60.392a, the affected facility is in 
compliance. Each monthly calculation is a performance test for the 
purposes of this subpart.

comply with the applicable emission limit specified under Sec. 60.392a.
    (1) Calculate the mass of VOC emission reduction for the coating 
operation controlled by the solvent recovery system using a liquid-
liquid material balance for each affected facility by applying the 
volatile organic matter collection and recovery efficiency to the mass 
of VOC contained in the coatings and thinners used in the coating 
operation controlled by the solvent recovery system during each month. 
Perform a liquid-liquid material balance for each month as specified in 
paragraphs (l)(1) through (6) of this section.
    (2) For each solvent recovery system, install, calibrate, maintain, 
and operate according to the manufacturer's specifications, a device 
that indicates the cumulative amount of volatile organic matter 
recovered by the solvent recovery system each month. The device must be 
initially certified by the manufacturer to be accurate to within 2.0 percent of the mass of volatile organic matter 
recovered.

for each calendar month using the equation in paragraph (i)(1) of this 
section.
    (5) Calculate the solvent recovery system's volatile organic matter 
collection and recovery efficiency (RV) for each affected 
facility using Equation 7 of this section:

          controlled by the solvent recovery system during the month.
n = Number of different thinners used in the coating operation 
          controlled by the solvent recovery system during the month.

    (6) For each affected facility, you may apply the solvent recovery 
system's volatile organic matter collection and recovery efficiency to 
the mass of VOC for the coating operation controlled by the solvent 
recovery system for each calendar month.
    (m) Deviations. You may request approval from the Administrator to 
use non-zero capture efficiencies and add-on control device efficiencies 
for any period of time in which a deviation, including a deviation 
during a period of startup, shutdown, or malfunction, from an emission 
limitation, operating limit or any CMS requirement for the capture 
system or add-on control device serving a controlled coating operation 
occurred.
    (1) If you have manually collected parameter data indicating that a 
capture system or add-on control device was operating normally during a 
CMS malfunction, a CMS out-of-control period, or associated repair, then 
these data may be used to support and document your request to use the 
normal capture efficiency or add-on control device efficiency for that 
period of deviation.
    (2) If you have data indicating the actual performance of a capture 
system or add-on control device (e.g., capture efficiency measured at a 
reduced flow rate or add-on control device efficiency measured at a 
reduced thermal oxidizer temperature) during a deviation, including a 
deviation during a period of startup, shutdown, or malfunction, from an 
emission limitation or operating limit or from any CMS requirement for 
the capture system or add-on control device serving a controlled coating 
operation, then these data may be used to support and document your 
request to use these values for that period of deviation.
    (3) You may recalculate the adjusted volume weighted average mass of 
VOC emitted per volume of applied coating solids after add-on controls 
in paragraph (j)(6) of this section, and the adjusted volume weighted

Administrator approval of the non-zero capture efficiency and add-on 
control device efficiency values based on data provided in accordance 
with paragraphs (m)(1) and (2) of this section.
    (n) No deviations. If there were no deviations from the emission 
limitations, submit a statement as part of the compliance report that

reporting period because the VOC emission rate for each compliance 
period was less than or equal to the applicable emission limit in Sec. 
60.392a, you achieved the operating limits required by Sec. 60.394a, 
and you achieved the work practice standards required by Sec. 60.392a

Sec. 60.394a  Add-on control device operating limits and monitoring requirements.

    During the performance tests required by Sec. 60.393a, if you use 
an add-on control device(s) to comply with the emission limits specified 
under Sec. 60.392a(a) through (c), you must establish add-on control 
device operating limits required by Sec. 60.392a(h) according to this 
section, unless approval has been received for alternative monitoring 
under Sec. 60.13(i) as specified in Sec. 60.392a(h).

[[Page 589]]

    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limit according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use all valid data collected during the performance test to 
calculate and record the average combustion temperature maintained 
during the performance test. This average combustion temperature is the 
minimum 3-hour average operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use all valid data collected during the performance test to 
calculate and record the average temperature just before the catalyst 
bed and the average temperature difference across the catalyst bed 
maintained during the performance test. The minimum 3-hour average 
operating limits for your catalytic oxidizer are the average temperature 
just before the catalyst bed maintained during the performance test of 
that catalytic oxidizer and 80 percent of the average temperature 
difference across the catalyst bed maintained during the performance 
test of that catalytic oxidizer, except during periods of low 
production, the latter minimum operating limit is to maintain a positive 
temperature gradient across the catalyst bed. A low production period is 
when production is less than 80 percent of production rate during the 
performance test of that catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use all valid data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures. If problems are found during the 
catalyst activity test, you must replace the catalyst bed or take other 
corrective action consistent with the manufacturer's recommendations.
    (ii) Monthly external inspection of the catalytic oxidizer system, 
including the burner assembly and fuel supply lines for problems and, as 
necessary, adjust the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal inspection of the catalyst bed to check for 
channeling, abrasion, and settling. If problems are found during the 
annual internal inspection of the catalyst, you must replace the 
catalyst bed or take other corrective action consistent with the 
manufacturer's recommendations. If the catalyst bed is replaced and is 
not of like or better kind and quality as the old catalyst, and is not 
consistent with the manufacturer's recommendations, then you must 
conduct a new performance test to determine destruction efficiency 
according to Sec. 60.396a. If

[[Page 590]]

a catalyst bed is replaced and the replacement catalyst is of like or 
better kind and quality as the old catalyst, and is consistent with the 
manufacturer's recommendations, then a new performance test to determine 
destruction efficiency is not required and you may continue to use the 
previously established operating limits for that catalytic oxidizer.
    (c) Regenerative carbon adsorbers. If your add-on control device is 
a regenerative carbon adsorber, establish the operating limits according 
to paragraphs (c)(1) and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle and 
the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use all valid data collected during the performance test to 
calculate and record the average condenser outlet (product side) gas 
temperature maintained during the performance test. This average 
condenser outlet gas temperature is the maximum 3-hour average operating 
limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) and (2) of this section.
    (1) During the performance test, you must monitor and record the 
desorption gas inlet temperature at least once every 15 minutes during 
each of the three runs of the performance test.
    (2) Use all valid data collected during the performance test to 
calculate and record the average desorption gas inlet temperature. The 
minimum operating limit for the concentrator is 8 degrees Celsius (15 
degrees Fahrenheit) below the average desorption gas inlet temperature 
maintained during the performance test for that concentrator. You must 
keep the set point for the desorption gas inlet temperature no lower 
than 6 degrees Celsius (10 degrees Fahrenheit) below the lower of that 
set point during the performance test for that concentrator and the 
average desorption gas inlet temperature maintained during the 
performance test for that concentrator.
    (f) Emission capture systems. For each capture device that is not 
part of a permanent total enclosure (PTE) that meets the criteria of 
Sec. 60.397a and that is not capturing emissions from a downdraft spray 
booth or from a flash-off area or bake oven associated with a downdraft 
spray booth, establish an operating limit for either the gas volumetric 
flow rate or duct static pressure, as specified in paragraphs (f)(1) and 
(2) of this section. The operating limit for a PTE is specified in table 
1 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
60.393a and described in Sec. 60.397a, you must monitor and record 
either the gas volumetric flow rate or the duct static pressure for each 
separate capture device in your emission capture system at least once 
every 15 minutes during each of the test runs at a point in the duct 
between the capture device and the add-on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device, 
using all valid data. This average gas volumetric flow rate or duct 
static pressure is the minimum operating limit for that specific capture 
device.
    (g) Monitoring requirements. If you use an add-on control device(s) 
to comply with the emission limits specified under Sec. 60.392a(a) 
through (c), you must install, operate, and maintain each CMS specified 
in paragraphs (c), (e), (f), and (g) of this section according to 
paragraphs (g)(1) through (6) of this

[[Page 591]]

section. You must install, operate, and maintain each CMS specified in 
paragraphs (h) and (i) of this section according to paragraphs (g)(3) 
through (5) of this section.
    (1) The CMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CMS.
    (4) You must maintain the CMS at all times in accordance with Sec. 
60.11(d) and have readily available necessary parts for routine repairs 
of the monitoring equipment.
    (5) You must operate the CMS and collect emission capture system and 
add-on control device parameter data at all times that a controlled 
coating operation is operating in accordance with Sec. 60.11(d).
    (6) Startups and shutdowns are normal operation for this source 
category. Emissions from these activities are to be included when 
determining if the standards specified in Sec. 60.392a(a) through (c) 
are being attained. You must not use emission capture system or add-on 
control device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Except for periods of required 
quality assurance or control activities, any period during which the CMS 
fails to operate and record data continuously as required by paragraph 
(g)(1) of this section or generates data that cannot be included in 
calculating averages as specified in this paragraph (g)(7) constitutes a 
deviation from the monitoring requirements.
    (h) Capture system bypass line. You must meet the requirements of 
paragraphs (h)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (h)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.

[[Page 592]]

    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 60.395a.
    (i) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used to treat desorbed concentrate streams from 
concentrators or carbon adsorbers), you must comply with the 
requirements in paragraphs (i)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor 
upstream of the catalyst bed. If you establish the operating parameters 
for a catalytic oxidizer under paragraphs (b)(1) through (3) of this 
section, you must also install a gas temperature monitor downstream of 
the catalyst bed. The temperature monitors must be in the gas stream 
immediately before and after the catalyst bed to measure the temperature 
difference across the bed. If you establish the operating parameters for 
a catalytic oxidizer under paragraphs (b)(4) through (6) of this 
section, you need not install a gas temperature monitor downstream of 
the catalyst bed.
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (g)(1) through (6) and (i)(3)(i) through 
(vii) of this section for each gas temperature monitoring device, unless 
approval has been received for alternative monitoring under Sec. 
60.13(i) as specified in Sec. 60.392a(h). For the purposes of this 
paragraph (i)(3), a thermocouple is part of the temperature sensor.

interference and chemical contaminants.
    (iv) The gas temperature sensor must be capable of recording the 
temperature continuously. If a gas temperature chart recorder is used, 
it must have a measurement sensitivity in the minor division of at least 
20 degrees Fahrenheit.
    (v) Perform an electronic calibration at least semiannually 
according to the procedures in the manufacturer's owner's manual. 
Following the electronic calibration, you must conduct a temperature 
sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a reading 
within 30 degrees Fahrenheit of the process temperature sensor reading.
    (vi) Conduct calibration and validation checks any time the sensor 
exceeds the manufacturer's specified maximum operating temperature range 
or install a new temperature sensor.
    (vii) At least monthly, inspect components for integrity and 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (j) Regenerative carbon adsorbers. If you are using a regenerative 
carbon adsorber as an add-on control device, you must monitor the total 
regeneration desorbing gas (e.g., steam or nitrogen) mass flow for each 
regeneration cycle, the carbon bed temperature after each regeneration 
and cooling cycle and comply with paragraphs (g)(3) through (5) and 
(j)(1) and (2) of this section.
    (1) The regeneration desorbing gas mass flow monitor must be an 
integrating device having a measurement sensitivity of plus or minus 10 
percent, capable of recording the total regeneration desorbing gas mass

recorded or 1 degree Fahrenheit, whichever is greater.
    (2) The temperature monitor must provide a gas temperature record at 
least once every 15 minutes.
    (l) Concentrators. If you are using a concentrator, such as a 
zeolite wheel or rotary carbon bed concentrator, you must install a 
temperature monitor in the desorption gas stream. The temperature 
monitor must meet the requirements in paragraphs (g)(1) through (6) and 
(i)(3) of this section.
    (m) Emission capture systems. The capture system monitoring system 
must comply with the applicable requirements in paragraphs (m)(1) and 
(2) of this section.
    (1) For each flow measurement device, you must meet the requirements 
in paragraphs (g)(1) through (6) and (m)(1)(i) through (iv) of this 
section.
    (i) Locate a flow sensor in a position that provides a 
representative flow measurement in the duct from each capture device in 
the emission capture system to the add-on control device.
    (ii) Reduce swirling flow or abnormal velocity distributions due to 
upstream and downstream disturbances.
    (iii) Conduct a flow sensor calibration check at least semiannually.
    (iv) At least monthly, inspect components for integrity, electrical

data are not entitled to confidential treatment, and the EPA is required 
to make emissions data available to the public. Thus, emissions data 
will not be protected as CBI and will be made publicly available. Owners 
or operators that assert a CBI claim for any information submitted under 
paragraph (i)(1) or (i)(2) of this section, must submit a complete file, 
including information claimed to be CBI, to the EPA. The file must be 
generated using the EPA's ERT or an alternate electronic file consistent 
with the XML schema listed on the EPA's ERT website. Owners or operators 
can submit CBI according to one of the two procedures in paragraph 
(i)(3)(i) or (ii) of this section. All CBI claims must be asserted at 
the time of submission.
    (i) If sending CBI through the postal service, submit the file on a 
compact disc, flash drive, or other commonly used electronic storage 
medium and clearly mark the medium as CBI. Owners or operators are 
required to mail the electronic medium to U.S. EPA/OAQPS/CORE CBI 
Office, Attention: Automobile and Light Duty Truck Surface Coating 
Operations Sector Lead, MD C404-02, 4930 Old Page Rd., Durham, NC 27703. 
The same file with the CBI omitted must be submitted to the EPA via the 
EPA's CDX as described in paragraphs (i)(1) and (2) of this section.
    (ii) The EPA preferred method for CBI submittal is for it to be 
transmitted electronically using email attachments, File Transfer 
Protocol (FTP), or other online file sharing services (e.g., Dropbox, 
OneDrive, Google Drive). Electronic submissions must be transmitted 
directly to the OAQPS CBI Office at the email address [email protected], 
and as described above, should be clearly identified as CBI and note 
Attention: Automobile and Light Duty Truck Surface Coating Operations 
Sector Lead. If assistance is needed with submitting large electronic 
files that exceed the file size limit for email attachments, and if you 
do not have your own file sharing service, you can email 
[email protected] to request a file transfer link.

    (j) Electronic submittal of reports. The owner or operator shall 
submit the reports listed in paragraphs (b) through (e) of this section 
following the procedures specified in paragraphs (j)(1) through (3) of 
this section. In addition to the information required in paragraphs (b) 
through (h) of this section, owners or operators are required to report 
excess emissions and a monitoring systems performance report and a 
summary report to the Administrator according to Sec. 60.7(c) and (d). 
Owners or operators are required by Sec. 60.7(c) and (d) to report the 
date, time, cause, and duration of each exceedance of the applicable 
emission limit specified in Sec. 60.392a(a), any malfunction of the air 
pollution control equipment, and any periods during which the CMS or 
monitoring device is inoperative, malfunctioning, or out-of-control. For 
each failure, the report must include a list of the affected sources or 
equipment and a description of the method used to estimate the 
emissions.
    (1) Effective date. On and after November 6, 2023, or once the 
reporting template has been available on the CEDRI website for 1-year, 
whichever date is later, owners or operators must use the appropriate 
spreadsheet template on the CEDRI website (https://www.epa.gov/
electronic-reporting-air-emissions/cedri) for this subpart. The date the 
reporting template for this subpart becomes available will be listed on 
the CEDRI website. The report must be submitted by the deadline 
specified in this subpart, regardless of the method by which the report 
is submitted. Submit all reports to the EPA via CEDRI, which can be 
accessed through the EPA's CDX (https://cdx.epa.gov/). The EPA will make 
all the information submitted through CEDRI available to the public 
without further notice to the owner or operator. Do not use CEDRI to 
submit information you claim as CBI. Any information submitted using 
CEDRI cannot later be claimed CBI. If you claim CBI, submit the report 
following the procedure described in paragraph (i)(3) of this section. 
The same file with the CBI omitted must be submitted to CEDRI as 
described in this paragraph.
    (2) System outage. Owner or operators that are required to submit a 
report electronically through CEDRI in the EPA's CDX, may assert a claim 
of EPA system outage for failure to timely comply with that reporting 
requirement. To assert a claim of EPA system outage, owners or operators 
must meet the requirements outlined in paragraphs (e)(2)(i) through 
(vii) of this section.

diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (v) You must provide to the Administrator a written description 
identifying:
    (A) The date(s) and time(s) when CDX or CEDRI was accessed, and the 
system was unavailable;
    (B) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (C) A description of measures taken or to be taken to minimize the 
delay in reporting; and
    (D) The date by which you propose to report, or if you have already 
met the reporting requirement at the time of the notification, the date 
you reported.
    (vi) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (vii) In any circumstance, the report must be submitted 
electronically as soon as possible after the outage is resolved.
    (3) Force majeure. Owner or operators that are required to submit a 
report electronically through CEDRI in the EPA's CDX, may assert a claim 
of force majeure for failure to timely comply with that reporting 
requirement. To assert a claim of force majeure, you must meet the 
requirements outlined

[[Page 598]]

in paragraphs (j)(3)(i) through (iv) of this section.
    (i) You may submit a claim if a force majeure event is about to 
occur, occurs, or has occurred or there are lingering effects from such 
an event within the period of time beginning five business days prior to 
the date the submission is due. For the purposes of this section, a 
force majeure event is defined as an event that will be or has been 
caused by circumstances beyond the control of the affected facility, its 
contractors, or any entity controlled by the affected facility that 
prevents you from complying with the requirement to submit a report 
electronically within the time period prescribed. Examples of such 
events are acts of nature (e.g., hurricanes, earthquakes, or floods), 
acts of war or terrorism, or equipment failure or safety hazard beyond 
the control of the affected facility (e.g., large scale power outage).
    (ii) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (iii) You must provide to the Administrator:
    (A) A written description of the force majeure event;
    (B) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;
    (C) A description of measures taken or to be taken to minimize the 
delay in reporting; and
    (D) The date by which you propose to report, or if you have already 
met the reporting requirement at the time of the notification, the date 
you reported.
    (iv) The decision to accept the claim of force majeure and allow an 
extension to the reporting deadline is solely within the discretion of 
the Administrator.
    (k) Recordkeeping. You must collect and keep records of the data and 
information specified in paragraphs (k)(1) through (12) of this section. 
Failure to collect and keep these records is a deviation from the 
applicable standard.
    (1) A copy of each notification and report that you submitted to 
comply with this subpart, and the documentation supporting each 
notification and report.
    (2) A current copy of information provided by materials suppliers or 
manufacturers, such as manufacturer's formulation data, or test data 
used to determine the mass fraction of VOC, the density and the volume 
fraction of coating solids for each coating, and the mass fraction of 
VOC and the density for each thinner. If you conducted testing to 
determine mass fraction of VOC, density, or volume fraction of coating 
solids, you must keep a copy of the complete test report. If you use 
information provided to you by the manufacturer or supplier of the 
material that was based on testing, you must keep the summary sheet of 
results provided to you by the manufacturer or supplier. If you use the 
results of an analysis conducted by an outside testing lab, you must 
keep a copy of the test report. You are not required to obtain the test 
report or other supporting documentation from the manufacturer or 
supplier.
    (3) For each month, the records specified in paragraphs (k)(3)(i) 
through (iii) of this section.
    (i) For each coating used for the affected source, a record of the 
volume used in each month, the mass fraction VOC content, the density, 
and the volume fraction of solids.
    (ii) For each thinner used in coating operations for the affected 
source, a record of the volume used in each month, the mass fraction VOC 
content, and the density.
    (iii) A record of the calculation of the VOC emission rate for the 
affected source for each month. This record must include all raw data, 
algorithms, and intermediate calculations. If the guidelines presented 
in the ``Protocol for Determining the Daily Volatile Organic Compound 
Emission Rate of Automobile and Light-Duty Truck Primer-Surfacer and 
Topcoat'' EPA-453/R-08-002 (incorporated by reference, see Sec. 60.17), 
are used, you must keep records of all data input to this protocol. If 
these data are maintained as electronic files, the electronic files, as 
well as any paper copies must be maintained. These data must be provided 
to the permitting authority on request on

of internal audits.
    (12) For each add-on control device and for each CMS, a copy of the 
equipment operating instructions must be maintained on-site for the life 
of the equipment in a location readily available to plant operators and 
inspectors. You may prepare your own equipment operating instructions, 
or they may be provided to you by the equipment supplier or other third 
party.
    (l) Record form and retention time. (1) Any records required to be 
maintained by this subpart that are submitted electronically via the 
EPA's CEDRI may be maintained in electronic format. This ability to 
maintain electronic copies does not affect the requirement for 
facilities to make records, data, and reports available upon request to 
a delegated air agency or the EPA as part of an on-site compliance 
evaluation.
    (2) Except as provided in paragraph (k)(12) of this section, you

Sec. 60.396a  Add-on control device destruction efficiency.

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 
60.393a(j)(4), except as provided in Sec. 60.8. You must conduct three 
test runs as specified in Sec. Sec. 60.8(f) and 60.394a, and each test 
run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use EPA Method 1 or 1A of appendix A-1 to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use EPA Method 2, 2A, 2C, 2D, or 2F of appendix A-1, or 2G of 
appendix A-2 to 40 CFR part 60, as appropriate, to measure gas 
volumetric flow rate.
    (3) Use EPA Method 3, 3A, or 3B of appendix A-2 to 40 CFR part 60, 
as appropriate, for gas analysis to determine dry molecular weight. The 
ASME/ANSI PTC 19.10-1981 (incorporated by reference, see Sec. 60.17), 
may be used as an alternative to EPA Method 3B.
    (4) Use EPA Method 4 of appendix A-3 to 40 CFR part 60 to determine 
stack gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon in the 
effluent gas leaving each stack not equipped with a control device and 
at the inlet and outlet of the add-on control device simultaneously, 
using either EPA Method 25 or 25A of appendix A-7 to 40 CFR part 60, as 
specified in paragraphs (b)(1) through (4) of this section. You must use 
the same method for both the inlet and outlet measurements.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million by volume (ppmv) at the control device outlet.

[[Page 601]]

    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppmv or less at the control device outlet.
    (3) Use Method 25A if the add-control device is not an oxidizer.
    (4) You may use EPA Method 18 of appendix A-6 to 40 CFR part 60 to 
subtract methane emissions from measured total gaseous organic mass 
emissions as carbon.
    (5) For Method 25 and 25A, the sampling time for each of three runs 
must be at least one hour. The minimum sample volume must be 0.003 dscm 
except that shorter sampling times or smaller volumes, when necessitated 
by process variables or other factors, may be approved by the 
Administrator. The Administrator will approve the sampling of 
representative stacks on a case-by-case basis if you can demonstrate to 
the satisfaction of the Administrator that the testing of representative 
stacks would yield results comparable to those that would be obtained by 
testing all stacks.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high-volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates (Mf) for the inlet and the outlet of the add-
on control device, using Equation 1 of this section. If there is more 
than one inlet or outlet to the add-on control device, you must 
calculate the total gaseous organic mass flow rate using Equation 1 of 
this section for each inlet and each outlet and then total all of the 
inlet emissions and total all of the outlet emissions.

Where:

Mf = Total gaseous organic emissions mass flow rate, kg per 
          hour (kg/h).

Cc = Concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, ppmv, dry 
          basis.

Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D,

          = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR09MY23.010

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.

Mfi = Total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.

Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 60.397a  Emission capture system efficiency.

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 60.393a. For purposes of this subpart, a spray booth air seal is 
not considered a natural draft opening in a PTE or a temporary total 
enclosure provided you demonstrate that the direction of air movement 
across the interface between the spray booth air seal and the spray 
booth is into the spray booth. For purposes of this subpart, a bake oven 
air seal is not considered a natural draft opening in a PTE or a 
temporary total enclosure provided you demonstrate that the direction of 
air movement across the interface between the bake oven air seal and the 
bake oven is into the bake oven. You may use lightweight strips of 
fabric or paper, or smoke tubes to make such demonstrations as part of 
showing that your capture system is a PTE or conducting a capture 
efficiency test using a temporary total enclosure. You cannot count air 
flowing from a spray booth air seal into a spray booth as air flowing 
through a natural draft opening into a PTE or into a temporary total 
enclosure unless you elect to treat that spray booth air seal as a 
natural draft opening. You cannot count air flowing from a bake oven air 
seal into a bake oven as air flowing through a natural draft opening 
into a PTE or into a temporary total enclosure unless you elect to treat 
that bake oven air seal as a natural draft opening.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings and thinners used in the coating operation are 
applied within the capture system, and coating solvent flash-off and 
coating curing and drying occurs within the capture system. For example, 
this criterion is not met if parts enter the open shop environment when 
being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the five procedures described in paragraphs (c) 
through (g) of this section to measure capture efficiency. For the 
protocols in paragraphs (c) and (d) of this section, the capture 
efficiency measurement must consist of three test runs. Each test run 
must be at least 3 hours duration or the length of a production run, 
whichever is longer, up to 8 hours. For the purposes of this test, a 
production run means the time required for a single part to go from the 
beginning to the end of production, which includes surface preparation 
activities and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid VOC in materials used in the coating 
operation to the mass of VOC emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings and thinners are applied, and all 
areas where emissions from these applied coatings and thinners 
subsequently occur, such as flash-off, curing, and drying areas. The 
areas of the coating operation where capture devices collect emissions 
for routing to an add-on control device, such as the entrance and exit 
areas of an oven or spray booth, must also be inside the enclosure. The 
enclosure must meet the applicable

[[Page 603]]

definition of a temporary total enclosure or building enclosure in 
Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204A or F of appendix M to 40 CFR part 51 to 
determine the mass fraction of VOC liquid input from each coating and 
thinner used in the coating operation during each capture efficiency 
test run.
    (3) Use Equation 1 of this section to calculate the total mass of 
VOC liquid input (VOCused) from all the coatings and thinners 
used in the coating operation during each capture efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR09MY23.011

Where:

VOCi = Mass fraction of VOC in coating or thinner, i, used in 
          the coating operation during the capture efficiency test run, 
          kg VOC per kg material.

Voli = Total volume of coating or thinner, i, used in the 
          coating operation during the capture efficiency test run, 
          liters.

Di = Density of coating or thinner, i, kg material per liter 
          material.

n = Number of different coatings and thinners used in the coating 
          operation during the capture efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of VOC emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR09MY23.012

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.

VOCused = Total mass of VOC liquid input used in the coating 
          operation during the capture efficiency test run, kg.

VOCuncaptured = Total mass of VOC that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of VOC 
emissions captured by the emission capture system to the mass of VOC 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings and thinners are applied, and all 
areas where emissions from these applied

[[Page 604]]

coatings and thinners subsequently occur, such as flash-off, curing, and 
drying areas. The areas of the coating operation where capture devices 
collect emissions generated by the coating operation for routing to an 
add-on control device, such as the entrance and exit areas of an oven or 
a spray booth, must also be inside the enclosure. The enclosure must 
meet the applicable definition of a temporary total enclosure or 
building enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or C of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of VOC emissions captured by the emission capture 
system during each capture efficiency test run as measured at the inlet 
to the add-on control device.
    (i) The sampling points for the Method 204B or C measurement must be 
upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously or 
sequentially measured in each duct, and the total emissions entering the 
add-on control device must be determined.
    (3) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of VOC emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute VOC for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR09MY23.013

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.

VOCcaptured = Total mass of VOC captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.

VOCuncaptured = Total mass of VOC that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Panel testing to determine the capture efficiency of flash-off 
or bake oven emissions. You may conduct panel testing to determine the 
capture efficiency of flash-off or bake oven emissions using ASTM Method 
D5087-02 (Reapproved 2021), ``Standard Test Method for Determining 
Amount of Volatile Organic Compound (VOC) Released from Solventborne 
Automotive Coatings and Available for Removal in a VOC Control Device 
(Abatement)'' (incorporated by reference, see Sec. 60.17), ASTM Method 
D6266-00a (Reapproved 2017), ``Test Method for Determining the Amount of 
Volatile Organic Compound (VOC) Released from Waterborne Automotive 
Coatings and Available for Removal in a VOC Control Device (Abatement)'' 
(incorporated by reference, see Sec. 60.17), or the guidelines 
presented in ``Protocol for Determining

[[Page 605]]

the Daily Volatile Organic Compound Emission Rate of Automobile and 
Light-Duty Truck Primer-Surfacer and Topcoat'' EPA-453/R-08-002 
(incorporated by reference, see Sec. 60.17). You may conduct panel 
testing on representative coatings as described in ``Protocol for 
Determining the Daily Volatile Organic Compound Emission Rate of 
Automobile and Light-Duty Truck Primer-Surfacer and Topcoat'' EPA-453/R-
08-002 (incorporated by reference, see Sec. 60.17).
    (1) Calculate the volume of coating solids deposited per volume of 
coating used for coating, i, or the composite volume of coating solids 
deposited per volume of coating used for the group of coatings including 
coating, i, used during the month in the spray booth(s) preceding the 
flash-off area or bake oven for which the panel test is conducted using 
Equation 4 of this section:
[GRAPHIC] [TIFF OMITTED] TR09MY23.014

Where:

Vsdep, i = Volume of coating solids deposited per volume of 
          coating used for coating, i, or composite volume of coating 
          solids deposited per volume of coating used for the group of 
          coatings including coating, i, in the spray booth(s) preceding 
          the flash-off area or bake oven for which the panel test is

          according to Sec. 60.393a(h), expressed as a decimal, for 
          example 60 percent must be expressed as 0.60. (Transfer 
          efficiency also may be determined by testing representative 
          coatings. The same coating groupings may be appropriate for 
          both transfer efficiency testing and panel testing. In this 
          case, all of the coatings in a panel test grouping would have 
          the same transfer efficiency.)

    (3) As an alternative, you may choose to express the results of your 
panel tests in units of mass of VOC per mass of coating solids deposited 
and convert such results to a percent using Equation 7 of this section. 
If you panel test representative coatings, then you may convert the 
panel test result for each representative coating either to a unique 
percent capture efficiency for each coating grouped with that 
representative coating by using coating specific values for the mass of 
coating solids deposited per mass of coating used, mass fraction VOC, 
transfer efficiency, and mass fraction solids in Equations 7 and 8 of 
this section; or to a composite percent capture efficiency for the group 
of coatings by using composite values for the group of coatings for the 
mass of coating solids deposited per mass of coating used and average 
values for the mass of VOC per volume of coating, average values for the 
group of coatings for mass fraction VOC, transfer efficiency, and mass 
fraction solids in Equations 7 and 8 of this section. If you panel test 
each coating, then you must convert the panel test result for each 
coating to a unique percent capture efficiency for that coating by using 
coating specific values for the mass of coating solids deposited per 
mass of coating used, mass fraction VOC, transfer efficiency, and mass 
fraction solids in Equations 7 and 8 of this section. Panel test results 
expressed in units of mass of VOC per mass of coating solids deposited 
must be converted to percent capture efficiency using Equation 6 of this 
section:

          solids deposited per mass of coating used for the group of 
          coatings, including coating, i, in the spray booth(s) 
          preceding the flash-off area or bake oven for which the panel 
          test is conducted, kg of solids deposited per kg of coating 
          used, from Equation 8 of this section.

Wvocc,i = Mass fraction of VOC in coating, i, or average mass 
          fraction of VOC for the group of coatings, including coating, 
          i, kg VOC per kg coating, determined by EPA Method 24 
          (appendix A-7 to 40 CFR part 60) or the guidelines for 
          combining analytical VOC content and formulation solvent 
          content presented in Section 9 of ``Protocol for Determining 
          the Daily Volatile Organic Compound Emission Rate of

          EPA-453/R-08-002'' (incorporated by reference, see Sec. 
          60.17).

    (4) Calculate the mass of coating solids deposited per mass of 
coating used for each coating or the composite mass of coating solids 
deposited per mass of coating used for each group of coatings used 
during the month in the spray booth(s) preceding the flash-off area or 
bake oven for which the panel test is conducted using Equation 7 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR09MY23.017

Where:

Wsdep, i = Mass of coating solids deposited per mass of 
          coating used for coating, i, or composite mass of coating 
          solids deposited per mass of coating used for the group of 
          coatings including coating, i, in

          for which the panel test is conducted, kg coating solids 
          deposited per kg coating used.

Ws, i = Mass fraction of coating solids for coating, i, or 
          average mass fraction of coating solids for the group of 
          coatings including coating, i, kg coating solids per kg 
          coating, determined by EPA Method 24 (appendix A-7 to 40 CFR 
          part 60) or the guidelines for combining analytical VOC 
          content and formulation solvent content presented in 
          ``Protocol for Determining the Daily Volatile Organic Compound 
          Emission Rate of Automobile and Light-Duty Truck Primer-
          Surfacer and Topcoat, EPA-453/R-08-002'' (incorporated by 
          reference, see Sec. 60.17).

TEc, i = Transfer efficiency of coating, i, or average 
          transfer efficiency for the group of coatings including 
          coating, i, in the spray booth(s) for the flash-off area or 
          bake oven for which the panel test is conducted determined 
          according to Sec. 60.393a(h), expressed as a decimal, for 
          example 60 percent must be expressed as 0.60. (Transfer 
          efficiency also may be determined by testing representative 
          coatings. The same coating groupings may be appropriate used 
          for both transfer efficiency testing and panel testing. In 
          this case, all of the coatings in a panel test grouping would 
          have the same transfer efficiency.)

    (f) Alternative capture efficiency procedure. As an alternative to 
the procedures specified in paragraphs (c) through (e) and (g) of this 
section, you may determine capture efficiency using any other capture 
efficiency protocol and test methods that satisfy the criteria of either 
the Data Quality Objective (DQO) or Lower Confidence Limit (LCL) 
approach as described in appendix A to subpart KK of 40 CFR part 63.
    (g) Panel testing to determine the capture efficiency of spray booth 
emissions from solvent-borne coatings. You may conduct panel testing to 
determine the capture efficiency of spray booth emissions from solvent-
borne coatings using the procedure in appendix A to this subpart.

  Sec. Appendix A to Subpart MMa of Part 60--Determination of Capture 
Efficiency of Automobile and Light-Duty Truck Spray Booth Emissions From 
               Solvent-Borne Coatings Using Panel Testing

    1.0 Applicability, Principle, and Summary of Procedure.
    1.1 Applicability.
    This procedure applies to the determination of capture efficiency of 
automobile and light-duty truck spray booth emissions from solvent-borne 
coatings using panel testing. This procedure can be used to determine 
capture efficiency for partially controlled spray booths (e.g., 
automated spray zones controlled and manual spray zones not controlled) 
and for fully controlled spray booths.
    1.2 Principle.
    1.2.1 The volatile organic compounds (VOC) associated with the 
coating solids deposited on a part (or panel) in a controlled spray 
booth zone (or group of contiguous controlled spray booth zones) 
partition themselves between the VOC that volatilize in the controlled 
spray booth zone (principally between the spray gun and the part) and 
the VOC that remain on the part (or panel) when the part (or panel) 
leaves the controlled spray booth zone. For solvent-borne coatings 
essentially all of the VOC associated with the coating solids deposited 
on a part (or panel) in a controlled spray booth zone that volatilize in 
the controlled spray booth zone pass through the waterwash and are 
exhausted from the controlled spray booth zone to the control device.
    1.2.2 The VOC associated with the overspray coating solids in a 
controlled spray booth zone partition themselves between the VOC that 
volatilize in the controlled spray booth zone and the VOC that are still 
tied to the overspray coating solids when the overspray coating solids 
hit the waterwash. For solvent-borne coatings almost all of the VOC 
associated with the overspray coating solids that volatilize in the 
controlled spray booth zone pass through the waterwash and are exhausted 
from the controlled spray booth zone to the control device. The exact 
fate of the VOC still tied to the overspray coating solids when the 
overspray coating solids hit the waterwash is unknown. This procedure 
assumes that none of the VOC still tied to the overspray coating solids 
when the overspray coating solids hit the waterwash are captured and 
delivered to the control device. Much of this VOC may become entrained 
in the water along with the overspray coating solids. Most of the VOC 
that become entrained in the water along with the overspray coating 
solids leave the water, but the point at which this VOC leave the water 
is unknown. Some of the VOC still tied to the overspray coating solids 
when the overspray coating solids hit the waterwash may pass through the 
waterwash and be exhausted from the controlled spray booth zone to the 
control device.
    1.2.3 This procedure assumes that the portion of the VOC associated 
with the overspray coating solids in a controlled spray booth zone that 
volatilizes in the controlled spray booth zone, passes through the 
waterwash and is exhausted from the controlled spray booth zone to the 
control device is equal to the portion of the VOC associated with the 
coating solids deposited on a part (or panel) in that controlled spray 
booth zone that volatilizes in the controlled spray booth zone, passes 
through the waterwash, and is exhausted from the controlled spray

[[Page 610]]

booth zone to the control device. This assumption is equivalent to 
treating all of the coating solids sprayed in the controlled spray booth 
zone as if they are deposited coating solids (i.e., assuming 100 percent 
transfer efficiency) for purposes of using a panel test to determine 
spray booth capture efficiency.
    1.2.4 This is a conservative (low) assumption for the portion of the 
VOC associated with the overspray coating solids in a controlled spray 
booth zone that volatilizes in the controlled spray booth zone. Thus, 
this assumption results in an underestimate of conservative capture 
efficiency. The overspray coating solids have more travel time and 
distance from the spray gun to the waterwash than the deposited coating 
solids have between the spray gun and the part (or panel). Therefore, 
the portion of the VOC associated with the overspray coating solids in a 
controlled spray booth zone that volatilizes in the controlled spray 
booth zone should be greater than the portion of the VOC associated with 
the coating solids deposited on a part (or panel) in that controlled 
spray booth zone that volatilizes in that controlled spray booth zone.

                        1.3 Summary of Procedure

    1.3.1 A panel test is performed to determine the mass of VOC that 
remains on the panel when the panel leaves a controlled spray booth 
zone. The total mass of VOC associated with the coating solids deposited 
on the panel is calculated.
    1.3.2 The percent of the total VOC associated with the coating 
solids deposited on the panel in the controlled spray booth zone that 
remains on the panel when the panel leaves the controlled section of the 
spray booth is then calculated from the ratio of the two previously 
determined masses. The percent of the total VOC associated with the 
coating solids deposited on the panel in the controlled spray booth zone 
that is captured and delivered to the control device equals 100 minus 
this percentage. (The mass of VOC associated with the coating solids 
deposited on the panel which is volatilized and captured in the 
controlled spray booth zone equals the difference between the total mass 
of VOC associated with the coating solids deposited on the panel and the 
mass of VOC remaining with the coating solids deposited on the panel 
when the panel leaves the controlled spray booth zone.)
    1.3.3 The percent of the total VOC associated with the coating 
sprayed in the controlled spray booth zone that is captured and 
delivered to the control device is assumed to be equal to the percent of 
the total VOC associated with the coating solids deposited on the panel 
in the controlled spray booth zone that is captured and delivered to the 
control device. The percent of the total VOC associated with the coating 
sprayed in the entire spray booth that is captured and delivered to the 
control device can be calculated by multiplying the percent of the total 
VOC associated with the coating sprayed in the controlled spray booth 
zone that is captured and delivered to the control device by the 
fraction of coating sprayed in the spray booth that is sprayed in the 
controlled spray booth zone.

                              2.0 Procedure

    2.1 You may conduct panel testing to determine the capture 
efficiency of spray booth emissions. You must follow the instructions 
and calculations in this appendix A, and use the panel testing 
procedures in ASTM D5087-02 (Reapproved 2021), ``Standard Test Method 
for Determining Amount of Volatile Organic Compound (VOC) Released from 
Solventborne Automotive Coatings and Available for Removal in a VOC 
Control Device (Abatement)'' (incorporated by reference, see Sec. 
60.17), or the guidelines presented in ``Protocol for Determining the 
Daily Volatile Organic Compound Emission Rate of Automobile and Light-
Duty Truck Primer-Surfacer and Topcoat'' EPA-453/R-08-002 (incorporated 
by reference, see Sec. 60.17). You must weigh panels at the points 
described in section 2.5 of this appendix A and perform calculations as 
described in sections 3 and 4 of this appendix A. You may conduct panel 
tests on the production paint line in your facility or in a laboratory 
simulation of the production paint line in your facility.
    2.2 You may conduct panel testing on representative coatings as 
described in ``Protocol for Determining the Daily Volatile Organic 
Compound Emission Rate of Automobile and Light-Duty Truck Primer-
Surfacer and Topcoat'' EPA-453/R-08-002 (incorporated by reference, see 
Sec. 60.17). If you panel test representative coatings, then you may 
calculate either a unique percent capture efficiency value for each 
coating grouped with that representative coating, or a composite percent 
capture efficiency value for the group of coatings. If you panel test 
each coating, then you must convert the panel test result for each 
coating to a unique percent capture efficiency value for that coating.
    2.3 Identification of Controlled Spray Booth Zones.
    You must identify each controlled spray booth zone or each group of 
contiguous controlled spray booth zones to be tested. (For example, a 
controlled bell zone immediately followed by a controlled robotic zone.) 
Separate panel tests are required for non-contiguous controlled spray 
booth zones. The flash zone between the last basecoat zone and the first 
clearcoat zone makes these zones non-contiguous.
    2.4 Where to Apply Coating to the Panel.
    If you are conducting a panel test for a single controlled spray 
booth zone, then you

[[Page 611]]

must apply coating to the panel only in that controlled spray booth 
zone. If you are conducting a panel test for a group of contiguous 
controlled spray booth zones, then you must apply coating to the panel 
only in that group of contiguous controlled spray booth zones.
    2.5 How to Process and When to Weigh the Panel.
    The instructions in this section pertain to panel testing of 
coating, i, or of the coating representing the group of coatings that 
includes coating, i.
    2.5.1 You must weigh the blank panel. (Same as in bake oven panel 
test.) The mass of the blank panel is represented by Wblank,i 
(grams).
    2.5.2 Apply coating, i, or the coating representing coating, i, to 
the panel in the controlled spray booth zone or group of contiguous 
controlled spray booth zones being tested (in plant test), or in a 
simulation of the controlled spray booth zone or group of contiguous 
controlled spray booth zones being tested (laboratory test).
    2.5.3 Remove and weigh the wet panel as soon as the wet panel leaves 
the controlled spray booth zone or group of contiguous controlled spray 
booth zones being tested. (Different than bake oven panel test.) This 
weighing must be conducted quickly to avoid further evaporation of VOC. 
The mass of the wet panel is represented by Wwet,i (grams).
    2.5.4 Return the wet panel to the point in the coating process or 
simulation of the coating process where it was removed for weighing.
    2.5.5 Allow the panel to travel through the rest of the coating 
process in the plant or laboratory simulation of the coating process. 
You must not apply any more coating to the panel after it leaves the 
controlled spray booth zone (or group of contiguous controlled spray 
booth zones) being tested. The rest of the coating process or simulation 
of the coating process consists of:
    2.5.5.1 All of the spray booth zone(s) or simulation of all of the 
spray booth zone(s) located after the controlled spray booth zone or 
group of contiguous controlled spray booth zones being tested and before 
the bake oven where the coating applied to the panel is cured,
    2.5.5.2 All of the flash-off area(s) or simulation of all of the 
flash-off area(s) located after the controlled spray booth zone or group 
of contiguous controlled spray booth zones being tested and before the 
bake oven where the coating applied to the panel is cured, and
    2.5.5.3 The bake oven or simulation of the bake oven where the 
coating applied to the panel is cured.
    2.5.6 After the panel exits the bake oven, you must cool and weigh 
the baked panel. (Same as in bake oven panel test.) The mass of the 
baked panel is represented by Wbaked,i (grams).

                         3.0 Panel Calculations

    The instructions in this section pertain to panel testing of 
coating, i, or of the coating representing the group of coatings that 
includes coating, i.
    3.1 The mass of coating solids (from coating, i, or from the coating 
representing coating, i, in the panel test) deposited on the panel 
equals the mass of the baked panel minus the mass of the blank panel as 
shown in Equation A-1.

Where:

Wsdep, i = Mass of coating solids (from coating, i, or from 
          the coating representing coating, i, in the panel test) 
          deposited on the panel, grams.

    3.2 The mass of VOC (from coating, i, or from the coating 
representing coating, i, in the panel test) remaining on the wet panel 
when the wet panel leaves the controlled spray booth zone or group of 
contiguous controlled spray booth zones being tested equals the mass of 
the wet panel when the wet panel leaves the controlled spray booth zone 
or group of contiguous controlled spray booth zones being tested minus 
the mass of the baked panel as shown in Equation A-2.
[GRAPHIC] [TIFF OMITTED] TR09MY23.019

Where:

Wrem, i = Mass of VOC (from coating, i, or from the coating 
          representing coating, i,

          in the panel test) remaining on the wet panel when the wet 
          panel leaves the controlled spray booth zone or group of 
          contiguous controlled spray booth zones being tested, grams.

    3.3 Calculate the mass of VOC (from coating, i, or from the coating 
representing coating, i, in the panel test) remaining on the wet panel 
when the wet panel leaves the controlled spray booth zone or group of 
contiguous controlled spray booth zones being tested per mass of coating 
solids deposited on the panel as shown in Equation A-3.
[GRAPHIC] [TIFF OMITTED] TR09MY23.020

Where:

Pm, i = Mass of VOC (from coating, i, or from the coating 
          representing coating, i, in the panel test) remaining on the 
          wet panel when the wet panel leaves the controlled spray booth 
          zone or group of contiguous controlled spray booth zones being 
          tested per mass of coating solids deposited on the panel, 
          grams of VOC remaining per gram of coating solids deposited.

Wrem, i = Mass of VOC (from coating, i, or from the coating 
          representing coating, i, in the panel test) remaining on the 
          wet panel when the wet panel leaves the controlled spray booth

    The instructions in this section pertain to panel testing of for 
coating, i, or of the coating representing the group of coatings that 
includes coating, i.
    4.1 If you panel test representative coatings, then you may convert 
the panel test result for each representative coating from section 3.3 
of this appendix A either to a unique percent capture efficiency value 
for each coating grouped with that representative coating by using 
coating specific values for the mass fraction coating solids and mass 
fraction VOC in section 4.2 of this appendix A, or to a composite 
percent capture efficiency value for the group of coatings by using the 
average values for the group of coatings for mass fraction coating 
solids and mass fraction VOC in section 4.2 of this appendix A. If you 
panel test each coating, then you must convert the panel test result for 
each coating to a unique percent capture efficiency value by using 
coating specific values for the mass fraction coating solids and mass 
fraction VOC in section 4.2 of this appendix A. The mass fraction of VOC 
in the coating and the mass fraction of solids in the coating must be 
determined by Method 24 (appendix A-7 to 40 CFR part 60) or by following 
the guidelines for combining analytical VOC content and formulation 
solvent content presented in ``Protocol for Determining the Daily 
Volatile Organic Compound Emission Rate of Automobile and Light-Duty 
Truck Primer-Surfacer and Topcoat'' EPA-453/R-08-002 (incorporated by 
reference, see Sec. 60.17).'

for the group of coatings including coating, i, associated with the 
coating solids deposited on the panel that remains on the wet panel when 
the wet panel leaves the controlled spray booth zone or group of 
contiguous controlled spray booth zones being tested is calculated using

Sec. 60.432  Standard for volatile organic compounds.

    During the period of the performance test required to be conducted 
by Sec. 60.8 and after the date required for completion of the test, no 
owner or operator subject to the provisions of this subpart shall cause 
to be discharged into the atmosphere from any affected facility VOC 
equal to more than 16 percent of the total mass of VOC solvent and water 
used at that facility during any one performance averaging period. The 
water used includes only that water contained in the waterborne raw inks 
and related coatings and the water

[[Page 620]]

added for dilution with waterborne ink systems.



Sec. 60.433  Performance test and compliance provisions.

    (a) The owner or operator of any affected facility (or facilities) 
shall conduct performance tests in accordance with Sec. 60.8, under the 
following conditions:
    (1) The performance averaging period for each test is 30 consecutive 
calendar days and not an average of three separate runs as prescribed 
under Sec. 60.8(f).
    (2) Except as provided under paragraphs (f) and (g) of this section, 
if affected facilities routinely share the same raw ink storage/handling 
system with existing facilities, then temporary measurement procedures 
for segregating the raw inks, related coatings, VOC solvent, and water 
used at the affected facilities must be employed during the test. For 
this case, an overall emission percentage for the combined facilities as 
well as for only the affected facilities must be calculated during the 
test.
    (3) For the purpose of measuring bulk storage tank quantities of 
each color of raw ink and each related coating used, the owner or 
operator of any affected facility shall install, calibrate, maintain, 
and continuously operate during the test one or more:
    (i) Non-resettable totalizer metering device(s) for indicating the 
cumulative liquid volumes used at each affected facility; or
    (ii) Segregated storage tanks for each affected facility to allow 
determination of the liquid quantities used by measuring devices other 
than the press meters required under item (i) of this article; or
    (iii) Storage tanks to serve more than one facility with the liquid 
quantities used determined by measuring devices other than press meters, 
if facilities are combined as decribed under paragraph (d), (f), or (g) 
of this section.
    (4) The owner or operator may choose to install an automatic 
temperature compensator with any liquid metering device used to measure 
the raw inks, related coatings, water, or VOC solvent used, or VOC 
solvent recovered.
    (5) Records of the measured amounts used at the affected facility 
and the liquid temperature at which the amounts were measured are 
maintained for each shipment of all purchased material on at least a 
weekly basis for:
    (i) The raw inks and related coatings used;
    (ii) The VOC and water content of each raw ink and related coating 
used as determined according to Sec. 60.435;
    (iii) The VOC solvent and water added to the inks used;
    (iv) The VOC solvent used as a cleaning agent; and
    (v) The VOC solvent recovered.
    (6) The density variations with temperature of the raw inks, related 
coatings, VOC solvents used, and VOC solvent recovered are determined by 
the methods stipulated in Sec. 60.435(d).
    (7) The calculated emission percentage may be reported as rounded-
off to the nearest whole number.
    (8) Printing press startups and shutdowns are not included in the 
exemption provisions under Sec. 60.8(c). Frequent periods of press 
startups and shutdowns are normal operations and constitute 
representative conditions for the purpose of a performance test.
    (b) If an affected facility uses waterborne ink systems or a 
combination of waterborne and solvent-borne ink systems with a solvent 
recovery system, compliance is determined by the following procedures, 
except as provided in paragraphs (d), (e), (f), and (g) of this section:

determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.020

    (c) If an affected facility controlled by a solvent recovery system 
uses only solvent-borne ink systems, the owner or operator may choose to 
determine compliance on a direct mass or a density-corrected liquid 
volume basis. Except as provided in paragraphs (d), (e), (f), and (g) of 
this section, compliance is determined as follows:
    (1) On a direct mass basis, compliance is determined according to 
paragraph (b) of this section, except that the water term, 
Mv, does not apply.

          and cleaning solvents measured as used by volume with 
          different densities.

    (iv) The total corrected liquid volume of VOC solvent recovered is 
determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.023

where ``k'' is the total number of VOC solvents, miscellaneous solvent-
          borne waste inks, and waste VOC solvents measured as recovered 
          by volume with different densities.

determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.024

    (d) If two or more affected facilities are controlled by the same 
solvent recovery system, compliance is determined by the procedures 
specified in paragraph (b) or (c) of this section, whichever applies, 
except that (Lt)a and (Lr)a, 
(Mt)a, (Mr)a, and 
(Mv)a, are the collective amounts of VOC solvent 
and water corresponding to all the affected facilities controlled by 
that solvent recovery system. The average VOC emission percentage for 
each of the affected facilities controlled by that same solvent recovery 
system is assumed to be equal.
    (e) Except as provided under paragraph (f) of this section, if an 
existing facility (or facilities) and an affected facility (or 
facilities) are controlled in common by the same solvent recovery 
system, the owner or operator shall determine compliance by conducting a 
separate emission test on the existing facility (or facilities) and then 
conducting a performance test on the combined facilities as follows:
    (1) Before the initial startup of the affected facility (or 
facilities) and at any other time as requested by the Administrator, the 
owner or operator shall conduct emission test(s) on the existing 
facility (or facilities) controlled by the subject solvent recovery 
system. The solvent recovery system must handle VOC emissions from only 
the subject existing facility (or facilities), not from affected 
facilities, during the emission test.
    (2) During the emission test, the affected facilities are subject to 
the standard stated in Sec. 60.432.
    (3) The emission test is conducted over a 30 consecutive calendar 
day averaging period according to the conditions stipulated in 
paragraphs (a)(1) through (a)(5) of this section, except that the 
conditions pertain to only existing facilities instead of affected 
facilities.
    (4) The owner or operator of the existing facility (or facilities) 
shall provide the Administrator at least 30 days prior notice of the 
emission test to afford the Administrator the opportunity to have an 
observer present.
    (5) The emission percentage for the existing facility (or 
facilities) during the emission test is determined by one of the 
following procedures:
    (i) If the existing facility (or facilities) uses a combination of 
waterborne and solvent-borne ink systems, the average VOC emission 
percentage must be determined on a direct mass basis according to 
paragraph (b) or (d) of this section, whichever applies, with the 
following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.025

where the water and VOC solvent amounts pertain to only existing 
          facilities.


[[Page 623]]


    (ii) If the existing facility (or facilities) uses only solvent-
borne ink systems, the owner or operator may choose to determine the 
emission percentage either on a direct mass basis or a density-corrected 
liquid volume basis according to paragraph (c) or (d) of this section, 
whichever applies. On a direct mass basis, the average VOC emission 
percentage is determined by the equation presented in article (i) of 
this paragraph. On a density-corrected liquid volume basis, the average 
VOC emission percentage is determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.026

where the VOC solvent amounts pertain to only existing facilities.

    (6) The owner or operator of the existing facility (or facilities) 
shall furnish the Administrator a written report of the results of the 
emission test.
    (7) After completion of the separate emission test on the existing 
facility (or facilities), the owner or operator shall conduct 
performance test(s) on the combined facilities with the solvent recovery 
system handling VOC emissions from both the existing and affected 
facilities.
    (8) During performance test(s), the emission percentage for the 
existing facility (or facilities), Pe, is assumed to be equal 
to that determined in the latest emission test. The administrator may 
request additional emission tests if any physical or operational changes 
occur to any of the subject existing facilities.
    (9) The emission percentage for the affected facility (or 
facilities) during performance test(s) with both existing and affected 
facilities connected to the solvent recovery system is determined by one 
of the following procedures:

solvent-borne ink systems, the average VOC emission percentage must be 
determined on a direct mass basis according to paragraph (b) or (d) of 
this section, whichever applies, with the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.027

where (Mt)b and (Mr)b are 
          the collective VOC solvent amounts pertaining to all the 
          combined facilities.

    (ii) If all of the combined facilities use only solvent-borne ink 
systems, the owner or operator may choose to determine performance of 
the affected facility (or facilities) either on a direct mass basis or a 
density-corrected liquid volume basis according to paragraph (c) or (d) 
of this section, whichever applies. On a direct mass basis, the average 
VOC emission percentage is determined by the equation presented in 
article (i) of this paragraph. On a density-corrected liquid volume 
basis, the average VOC emission percentage is determined by the 
following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.028

where (Lt)b and (Lr)b are 
          the collective VOC solvent amounts pertaining to all the 
          combined facilities.

    (f) The owner or operator may choose to show compliance of the 
combined performance of existing and affected facilities controlled in 
common by the same solvent recovery system. A separate emission test for 
existing facilities is not required for this option. The combined 
performance is determined by one of the following procedures:
    (1) If any of the combined facilities uses both waterborne and 
solvent-borne ink systems, the combined average VOC emission percentage 
must be determined on a direct mass basis according to paragraph (b) or 
(d) of this section, whichever applies, with the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.308

    (2) If all of the combined facilities use only solvent-borne ink 
systems, the owner or operator may choose to determine performance 
either on a direct mass basis or a density-corrected liquid volume basis 
according to paragraph (c) or (d) of this section, whichever applies. On 
a direct mass basis,

[[Page 624]]

the average VOC emission percentage is determined by the equation 
presented in article (i) of this paragraph. On a density-corrected 
liquid volume basis, the average VOC emission percentage is determined 
by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.029

    (g) If all existing and affected facilities located within the same 
plant boundary use waterborne ink systems or solvent-borne ink systems 
with solvent recovery systems, the owner or operator may choose to show 
compliance on a plantwide basis for all the existing and affected 
facilities together. No separate emission tests on existing facilities 
and no temporary segregated liquid measurement procedures for affected 
facilities are required for this option. The plantwide performance is 
determined by one of the following procedures:
    (1) If any of the facilities use waterborne ink systems, the total 
plant average VOC emission percentage must be determined on a direct 
mass basis according to paragraph (b) of this section with the following 
equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.030

Where (Mt)f and (Mv)f are 
          the collective VOC solvent and water amounts used at all the 
          subject plant facilities during the performance test.

    (2) If all of the plant facilities use only solvent-borne ink 
systems, the owner or operator may choose to determine performance 
either on a direct mass basis or a density-corrected liquid volume basis 
according to paragraph (c) of this section. On a direct mass basis, the 
total plant average VOC emission percentage is determined by the 
equation presented in article (i) of this paragraph. On a density-
corrected liquid volume basis, the total plant average VOC emission 
percentage is determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TC01JN92.031

Where (Lt)f is the collective VOC solvent amount 
          used at all the subject plant facilities during the 
          performance test.

Sec. 60.434  Monitoring of operations and recordkeeping.

    (a) After completion of the performance test required under Sec. 
60.8, the owner or operator of any affected facility using waterborne 
ink systems or solvent-borne ink systems with solvent recovery systems 
shall record the amount of solvent and water used, solvent recovered, 
and estimated emission percentage for each performance averaging period 
and shall maintain these records for 2 years. The emission percentage is 
estimated as follows:
    (1) The performance averaging period for monitoring of proper 
operation and maintenance is a calendar month or 4 consecutive weeks, at 
the option of the owner or operator.
    (2) If affected facilities share the same raw ink storage/handling 
system with existing facilities, solvent and water used, solvent 
recovered, and emission percentages for the combined facilities may be 
documented. Separate emission percentages for only the affected 
facilities are not required in this case. The combined emission 
percentage is compared to the overall average for the existing and 
affected facilities' emission percentage determined during the most 
recent performance test.
    (3) Except as provided in article (4) of this paragraph, 
temperatures and liquid densities determined during the most recent 
performance test are used to calculate corrected volumes and mass 
quantities.
    (4) The owner or operator may choose to measure temperatures for 
determination of actual liquid densities during each performance 
averaging period. A different base temperature may be used for each 
performance averaging period if desired by the owner or operator.
    (5) The emission percentage is calculated according to the 
procedures under Sec. 60.433 (b) through (g), whichever applies, or by 
a comparable calculation which compares the total solvent recovered to 
the total solvent used at the affected facility.

Sec. 60.442  Standard for volatile organic compounds.

    (a) On and after the date on which the performance test required by 
Sec. 60.8 has been completed each owner or operator subject to this 
subpart shall:
    (1) Cause the discharge into the atmosphere from an affected 
facility not more than 0.20 kg VOC/kg of coating solids applied as 
calculated on a weighted average basis for one calendar month; or
    (2) Demonstrate for each affected facility;

[[Page 627]]

    (i) A 90 percent overall VOC emission reduction as calculated over a 
calendar month; or
    (ii) The percent overall VOC emission reduction specified in Sec. 
60.443(b) as calculated over a calendar month.



Sec. 60.443  Compliance provisions.

    (a) To determine compliance with Sec. 60.442 the owner or operator 
of the affected facility shall calculate a weighted average of the mass 
of solvent used per mass of coating solids applied for a one calendar 
month period according to the following procedures:
    (1) Determine the weight fraction of organics and the weight 
fraction of solids of each coating applied by using Reference Method 24 
or by the coating manufacturer's formulation data.
    (2) Compute the weighted average by the following equation:
    [GRAPHIC] [TIFF OMITTED] TC16NO91.032
    
    (3) For each affected facility where the value of G is less than or 
equal to 0.20 kg VOC per kg of coating solids applied, the affected 
facility is in compliance with Sec. 60.442(a)(1).
    (b) To determine compliance with Sec. 60.442(a)(2), the owner or 
operator shall calculate the required overall VOC emission reduction 
according to the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.033


If Rq is less than or equal to 90 percent, then the required 
overall VOC emission reduction is Rq. If Rq is 
greater than 90 percent, then the required overall VOC emission 
reduction is 90 percent.
    (c) Where compliance with the emission limits specified in Sec. 
60.442(a)(2) is achieved through the use of a solvent recovery system, 
the owner or operator shall determine the overall VOC emission reduction 
for a one calendar month period by the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.034


If the R value is equal to or greater than the Rq value 
specified in paragraph (b) of this section, then compliance with Sec. 
60.442(a)(2) is demonstrated.
    (d) Where compliance with the emission limit specified in Sec. 
60.442(a)(2) is achieved through the use of a solvent destruction 
device, the owner or operator shall determine calendar monthly 
compliance by comparing the monthly required overall VOC emission 
reduction specified in paragraph (b) of this section to the overall VOC 
emission reduction demonstrated in the most recent performance test 
which complied with Sec. 60.442(a)(2). If the monthly required overall 
VOC emission reduction is less than or equal to the overall VOC 
reduction of the most recent performance test, the affected facility is 
in compliance with Sec. 60.442(a)(2).
    (e) Where compliance with Sec. 60.442(a)(2) is achieved through the 
use of a solvent destruction device, the owner or operator shall 
continuously record the destruction device combustion temperature during 
coating operations for thermal incineration destruction devices or the 
gas temperature upstream and downstream of the incinerator catalyst bed 
during coating operations for catalytic incineration destruction 
devices. For thermal incineration destruction devices the owner or 
operator shall record all 3-hour periods (during actual coating 
operations) during which the average temperature of the device is more 
than 28 [deg]C (50 [deg]F) below the average temperature of the device 
during the most recent performance test complying with Sec. 
60.442(a)(2). For catalytic incineration destruction devices, the owner 
or operator shall record all 3-hour periods (during actual coating 
operations) during which the average temperature of the device 
immediately before the catalyst bed is more than 28 [deg]C (50 [deg]F) 
below the average temperature of the device during the most recent 
performance test complying with Sec. 60.442(a)(2), and all 3-hour 
periods (during actual coating operations) during which the average 
temperature difference across the catalyst

[[Page 628]]

bed is less than 80 percent of the average temperature difference of the 
device during the most recent performance test complying with Sec. 
60.442(a)(2).
    (f) After the initial performance test required for all affected 
facilities under Sec. 60.8, compliance with the VOC emission limitation 
and percentage reduction requirements under Sec. 60.442 is based on the 
average emission reduction for one calendar month. A separate compliance 
test is completed at the end of each calendar month after the initial 
performance test, and a new calendar month's average VOC emission 
reduction is calculated to show compliance with the standard.
    (g) If a common emission control device is used to recover or 
destroy solvent from more than one affected facility, the performance of 
that control device is assumed to be equal for each of the affected 
facilities. Compliance with Sec. 60.442(a)(2) is determined by the 
methods specified in paragraphs (c) and (d) of this section and is 
performed simultaneously on all affected facilities.
    (h) If a common emission control device is used to recover solvent 
from an existing facility (or facilities) as well as from an affected 
facility (or facilities), the overall VOC emission reduction for the 
affected facility (or facilities), for the purpose of compliance, shall 
be determined by the following procedures:
    (1) The owner or operator of the existing facility (or facilities) 
shall determine the mass of solvent recovered for a calendar month 
period from the existing facility (or facilities) prior to the 
connection of the affected facility (or facilities) to the emission 
control device.
    (2) The affected facility (or facilities) shall then be connected to 
the emission control device.
    (3) The owner or operator shall determine the total mass of solvent 
recovered from both the existing and affected facilities over a calendar 
month period. The mass of solvent determined in paragraph (h)(1) of this 
section from the existing facility shall be subtracted from the total 
mass of recovered solvent to obtain the mass of solvent recovered from 
the affected facility (or facilities). The overall VOC emission 
reduction of the affected facility (or facilities) can then be 
determined as specified in paragraph (c) of this section.
    (i) If a common emission control device(s) is used to destruct 
solvent from an existing facility (or facilities) as well as from an 
affected facility (or facilities), the overall VOC emission reduction 
for the affected facility (or facilities), for the purpose of 
compliance, shall be determined by the following procedures:
    (1) The owner or operator shall operate the emission control device 
with both the existing and affected facilities connected.
    (2) The concentration of VOC (in parts per million by volume) after 
the common emission control device shall be determined as specified in 
Sec. 60.444(c). This concentration is used in the calculation of 
compliance for both the existing and affected facilities.
    (3) The volumetric flow out of the common control device 
attributable to the affected facility (or facilities) shall be 
calculated by first determining the ratio of the volumetric flow 
entering the common control device attributable to the affected facility 
(facilities) to the total volumetric flow entering the common control 
device from both existing and affected facilities. The multiplication of 
this ratio by the total volumetric flow out of the common control device 
yields the flow attributable to the affected facility (facilities). 
Compliance is determined by the use of the equation specified in Sec. 
60.444(c).
    (j) Startups and shutdowns are normal operation for this source 
category. Emissions from these operations are to be included when 
determining if the standard specified at Sec. 60.442(a)(2) is being 
attained.

satisfied that the enclosure is totally capturing fugitive VOC 
emissions, then no additional total enclosure will be required for the 
performance test.
    (iii) For each affected facility where the value of R is greater 
than or equal to the value of Rq calculated in Sec. 
60.443(b), compliance with Sec. 60.442(a)(2) is demonstrated.

container at a point where the sample will be representative of the 
coating applied to the web substrate.
    (b) Method 25 shall be used to determine the VOC concentration, in 
parts per million by volume, of each effluent gas stream entering and 
exiting the solvent destruction device or its equivalent, and each 
effluent gas stream emitted directly to the atmosphere. Methods 1, 2, 3, 
and 4 shall be used to determine the sampling location, volumetric 
flowrate, molecular weight, and moisture of all sampled gas streams. For 
Method 25, the sampling time for each of three runs must be at least 1 
hour. The minimum sampling volume must be 0.003 dscm except that shorter 
sampling times or smaller volumes, when necessitated by process 
variables or other factors, may be approved by the Administrator.
    (c) If the owner or operator can demonstrate to the Administrator's 
satisfaction that testing of representative stacks yields results 
comparable to those that would be obtained by testing all stacks, the 
Administrator will approve testing of representative stacks on a case-
by-case basis.

m is the number of gas streams leaving the control device and entering 
          the atmosphere.


The owner or operator of the affected facility shall construct the VOC 
emission reduction system so that all volumetric flow rates and total

methods and procedures specified in Sec. 60.466. The owner or operator 
of the affected facility shall construct a temporary enclosure around 
the coating applicator and flashoff area during the performance test for 
the purpose of evaluating the capture efficiency of the system. The 
enclosure must be maintained at a negative pressure to ensure that all

affected facility prior to the performance test and the Administrator is 
satisfied that the enclosure is adequately containing VOC emissions, no 
additional enclosure is required for the performance test.
    (C) Determine overall reduction efficiency (R) using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.045


If the overall reduction efficiency (R) is equal to or greater than

0.90, the average total VOC emissions to the atmosphere per unit volume 
of coating solids applied (N) shall be computed as follows.

    (iii) Calculate the volume-weighted average of VOC emissions to the 
atmosphere (N) during each calendar month by the following equation:

shall be used for determining the VOC content of each coating as applied 
to the surface of the metal coil. In the event of a dispute, Method 24 
shall be the reference method. When VOC content of waterborne coatings, 
determined by Method 24, is used to determine compliance of affected 
facilities, the results of the Method 24 analysis shall be adjusted as 
described in Section 12.6 of Method 24;
    (2) Method 25, both for measuring the VOC concentration in each gas

methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (c) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.472 as follows:
    (1) The emission rate (E) of particulate matter shall be computed 
for each run using the following equation:

E = (cs Qsd)/(PK)

the coating blow or non-coating blow, whichever is greater, and 2.25 
dscm (79.4 dscf).
    (3) For the saturator, the asphalt roofing production rate (P) for 
each run shall be determined as follows: The amount of asphalt roofing 
produced on the shingle or saturated felt process lines shall be 
obtained by direct measurement. The asphalt roofing production rate is 
the amount produced divided by the time taken for the run.
    (4) For the blowing still, the asphalt charging rate (P) shall be 
computed for each run using the following equation:

P = (Vd)/(K' [thetas])

where:

    (i) The volume (V) of asphalt charged shall be measured by any means 
accurate to within 10 percent.
    (ii) The density (d) of the asphalt shall be computed using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.015

Where:

d = Density of the asphalt, kg/m\3\ (lb/ft\3\)

     = 64.70 lb/ft\3\ (English Units)
K2 = 0.6176 kg/(m\3\ [deg]C) (metric units)
     = 0.0694 lb/(ft\3\ [deg]F) (English Units)
Ti = temperature at the start of the blow, [deg]C ( deg;F)

    (5) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (d) The Administrator will determine compliance with the standards 
in Sec. 60.472(a)(3) by using Method 22, modified so that readings are 
recorded every 15 seconds for a period of consecutive observations 
during representative conditions (in accordance with Sec. 60.8(c)) 
totaling 60 minutes. A performance test shall consist of one run.
    (e) The owner or operator shall use the monitoring device in Sec. 
60.473 (a) or (b) to monitor and record continuously the temperature 
during the particulate matter run and shall report the results to the 
Administrator with the performance test results.
    (f) If at a later date the owner or operator believes that the 
emission limits in Sec. 60.472(a) and (b) are being met even though one 
of the conditions listed in this paragraph exist, he may submit a 
written request to the Administrator to repeat the performance test and 
procedure outlined in paragraph (c) of this section.
    (1) The temperature measured in accordance with Sec. 60.473(a) is 
exceeding that measured during the performance test.
    (2) The temperature measured in accordance with Sec. 60.473(b) is 
lower than that measured during the performance test.
    (g) If fuel oil is to be used to fire an afterburner used to control 
emissions from a blowing still, the owner or operator may petition the 
Administrator in accordance with Sec. 60.11(e) of the General 
Provisions to establish an opacity standard for the blowing still that 
will be the opacity standard when fuel oil is used to fire the 
afterburner. To obtain this opacity standard, the owner or operator must 
request the Administrator to determine opacity during an initial, or 
subsequent, performance test when fuel oil is used to fire the 
afterburner. Upon receipt of the results of the performance test, the 
Administrator will make a finding concerning compliance with the mass 
standard for the blowing still. If the Administrator finds that the 
facility was in compliance with the mass standard during the performance 
test but failed to meet the zero opacity

[[Page 648]]

standard, the Administrator will establish and promulgate in the Federal 
Register an opacity standard for the blowing still that will be the 
opacity standard when fuel oil is used to fire the afterburner. When the 
afterburner is fired with natural gas, the zero percent opacity remains 
the applicable opacity standard.

Sec. 60.485  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
standards in Sec. Sec. 60.482-1 through 60.482-10, 60.483, and 60.484 
as follows:
    (1) Method 21 shall be used to determine the presence of leaking 
sources. The instrument shall be calibrated before use each day of its 
use by the procedures specified in Method 21. The following calibration 
gases shall be used:
    (i) Zero air (less than 10 ppm of hydrocarbon in air); and
    (ii) A mixture of methane or n-hexane and air at a concentration of 
about, but less than, 10,000 ppm methane or n-hexane.

    (1) The requirements of paragraph (b) shall apply.
    (2) Method 21 shall be used to determine the background level. All 
potential leak interfaces shall be traversed as close to the interface 
as possible. The arithmetic difference between the maximum concentration 
indicated by the instrument and the background level is compared with 
500 ppm for determining compliance.
    (d) The owner or operator shall test each piece of equipment unless 
he demonstrates that a process unit is not in VOC service, i.e., that 
the VOC content would never be reasonably expected to exceed 10 percent 
by weight. For purposes of this demonstration, the following methods and 
procedures shall be used:
    (1) Procedures that conform to the general methods in ASTM E260-73, 
91, or 96, E168-67, 77, or 92, E169-63, 77, or 93 (incorporated by 
reference--see Sec. 60.17) shall be used to determine the percent VOC 
content in the process fluid that is contained in or contacts a piece of 
equipment.
    (2) Organic compounds that are considered by the Administrator to 
have negligible photochemical reactivity may be excluded from the total 
quantity of organic compounds in determining the VOC content of the 
process fluid.
    (3) Engineering judgment may be used to estimate the VOC content, if 
a piece of equipment had not been shown previously to be in service. If 
the Administrator disagrees with the judgment, paragraphs (d) (1) and 
(2) of this section shall be used to resolve the disagreement.
    (e) The owner or operator shall demonstrate that a piece of 
equipment is in light liquid service by showing that all the following 
conditions apply:
    (1) The vapor pressure of one or more of the organic components is 
greater than 0.3 kPa at 20 [deg]C (1.2 in. H2O at 68 [deg]F). 
Standard reference texts or ASTM D2879-83, 96, or 97 (incorporated by 
reference--see Sec. 60.17) shall be used to determine the vapor 
pressures.
    (2) The total concentration of the pure organic components having a 
vapor pressure greater than 0.3 kPa at 20 [deg]C (1.2 in. H2O 
at 68 [deg]F) is equal to or greater than 20 percent by weight.
    (3) The fluid is a liquid at operating conditions.
    (f) Samples used in conjunction with paragraphs (d), (e), and (g) of 
this section shall be representative of the process fluid that is 
contained in or contacts the equipment or the gas being combusted in the 
flare.
    (g) The owner or operator shall determine compliance with the 
standards of flares as follows:
    (1) Method 22 shall be used to determine visible emissions.

    (4) The net heating value (HT) of the gas being combusted 
in a flare shall be computed using the following equation:
[GRAPHIC] [TIFF OMITTED] TR16NO07.039

Where:

K = Conversion constant, 1.740 x 10-7 (g-mole)(MJ)/(ppm-scm-
          kcal) (metric units) = 4.674 x 10-6 [(g-mole)(Btu)/
          (ppm-scf-kcal)] (English units)
Ci = Concentration of sample component ``i,'' ppm
Hi = Net heat of combustion of sample component ``i'' at 25 
          [deg]C and 760 mm Hg (77 [deg]F and 14.7 psi), kcal/g-mole

are those listed in Section 1.1 of ASTM D6420-99, and the target 
concentration is between 150 parts per billion by volume and 100 parts 
per million by volume) and ASTM D2504-67, 77 or 88 (Reapproved 1993) 
(incorporated by reference--see Sec. 60.17) shall be used to determine 
the concentration of sample component ``i.''
    (6) ASTM D2382-76 or 88 or D4809-95 (incorporated by reference--see 
Sec. 60.17) shall be used to determine the net heat of combustion of 
component ``i'' if published values are not available or cannot be 
calculated.
    (7) Method 2, 2A, 2C, or 2D, as appropriate, shall be used to 
determine the actual exit velocity of a flare. If needed, the 
unobstructed (free) cross-sectional area of the flare tip shall be used.
    (h) The owner or operator shall determine compliance with Sec. 
60.483-1 or Sec. 60.483-2 as follows:
    (1) The percent of valves leaking shall be determined using the 
following equation:

%VL = (VL/VT) * 100

Where:

%VL = Percent leaking valves
VL = Number of valves found leaking
VT = The sum of the total number of valves monitored

    (2) The total number of valves monitored shall include difficult-to-
monitor and unsafe-to-monitor valves only during the monitoring period 
in which those valves are monitored.
    (3) The number of valves leaking shall include valves for which 
repair has been delayed.
    (4) Any new valve that is not monitored within 30 days of being 
placed in service shall be included in the number of valves leaking and 
the total number of valves monitored for the monitoring period in which 
the valve is placed in service.
    (5) If the process unit has been subdivided in accordance with Sec. 
60.482-7(c)(1)(ii), the sum of valves found leaking during a monitoring 
period includes all subgroups.
    (6) The total number of valves monitored does not include a valve 
monitored to verify repair.

    (ii) If the percent leaking connectors in the process unit was 
greater than or equal to 0.25 percent but less than 0.5 percent, then 
monitor within 4 years. An owner or operator may comply with the 
requirements of this paragraph by monitoring at least 40 percent of the 
connectors within 2 years of the start of the monitoring period, 
provided all connectors have been monitored by the end of the 4-year 
monitoring period.
    (iii) If the percent leaking connectors in the process unit was less 
than 0.25 percent, then monitor as provided in paragraph (b)(3)(iii)(A) 
of this section and either paragraph (b)(3)(iii)(B) or (b)(3)(iii)(C) of 
this section, as appropriate.
    (A) An owner or operator shall monitor at least 50 percent of the 
connectors within 4 years of the start of the monitoring period.
    (B) If the percent of leaking connectors calculated from the 
monitoring results in paragraph (b)(3)(iii)(A) of this section is 
greater than or equal to 0.35 percent of the monitored connectors, the 
owner or operator shall monitor as soon as practical, but within the 
next 6 months, all connectors that have not yet been monitored during 
the monitoring period. At the conclusion of monitoring, a new monitoring 
period shall be started pursuant to paragraph (b)(3) of this section, 
based on the percent of leaking connectors within the total monitored 
connectors.
    (C) If the percent of leaking connectors calculated from the 
monitoring results in paragraph (b)(3)(iii)(A) of this section is less 
than 0.35 percent of the monitored connectors, the owner or operator 
shall monitor all connectors that have not yet been monitored within 8 
years of the start of the monitoring period.
    (iv) If, during the monitoring conducted pursuant to paragraphs 
(b)(3)(i) through (iii) of this section, a connector is found to be 
leaking, it shall be re-monitored once within 90 days after repair to 
confirm that it is not leaking.
    (v) The owner or operator shall keep a record of the start date and 
end date

[[Page 683]]

of each monitoring period under this section for each process unit.
    (c) For use in determining the monitoring frequency, as specified in 
paragraphs (a) and (b)(3) of this section, the percent leaking 
connectors as used in paragraphs (a) and (b)(3) of this section shall be 
calculated by using the following equation:

%CL = CL / Ct * 100

Where:

%CL = Percent of leaking connectors as determined through 
          periodic monitoring required in paragraphs (a) and (b)(3)(i) 
          through (iii) of this section.
CL = Number of connectors measured at 500 ppm or greater, by 
          the method specified in Sec. 60.485a(b).
Ct = Total number of monitored connectors in the process unit 
          or affected facility.

    (d) When a leak is detected pursuant to paragraphs (a) and (b) of 
this section, it shall be repaired as soon as practicable, but not later 
than 15 calendar days after it is detected, except as provided in Sec. 
60.482-9a. A first attempt at repair as defined in this subpart shall be 
made no later than 5 calendar days after the leak is detected.
    (e) Any connector that is designated, as described in Sec. 
60.486a(f)(1), as an unsafe-to-monitor connector is exempt from the 
requirements of paragraphs (a) and (b) of this section if:
    (1) The owner or operator of the connector demonstrates that the 
connector is unsafe-to-monitor because monitoring personnel would be 
exposed to an immediate danger as a consequence of complying with 
paragraphs (a) and (b) of this section; and
    (2) The owner or operator of the connector has a written plan that 
requires monitoring of the connector 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 (d) of this section if a leak 
is detected.
    (f) Inaccessible, ceramic, or ceramic-lined connectors. (1) Any 
connector that is inaccessible or that is ceramic or ceramic-lined 
(e.g., porcelain, glass, or glass-lined), is exempt from the monitoring 
requirements of paragraphs (a) and (b) of this section, from the leak 
repair requirements of paragraph (d) of this section, and from the 
recordkeeping and reporting requirements of Sec. Sec. 63.1038 and 
63.1039. An inaccessible connector is one that meets any of the 
provisions specified in paragraphs (f)(1)(i) through (vi) of this 
section, as applicable:
    (i) Buried;
    (ii) Insulated in a manner that prevents access to the connector by 
a monitor probe;
    (iii) Obstructed by equipment or piping that prevents access to the 
connector by a monitor probe;
    (iv) Unable to be reached from a wheeled scissor-lift or hydraulic-
type scaffold that would allow access to connectors up to 7.6 meters (25 
feet) above the ground;
    (v) Inaccessible because it would require elevating the monitoring 
personnel more than 2 meters (7 feet) above a permanent support surface 
or would require the erection of scaffold; or
    (vi) Not able to be accessed at any time in a safe manner to perform 
monitoring. Unsafe access includes, but is not limited to, the use of a 
wheeled scissor-lift on unstable or uneven terrain, the use of a 
motorized man-lift basket in areas where an ignition potential exists, 
or access would require near proximity to hazards such as electrical 
lines, or would risk damage to equipment.
    (2) If any inaccessible, ceramic, or ceramic-lined connector is 
observed by visual, audible, olfactory, or other means to be leaking, 
the visual, audible, olfactory, or other indications of a leak to the 
atmosphere shall be eliminated as soon as practical.
    (g) Except for instrumentation systems and inaccessible, ceramic, or 
ceramic-lined connectors meeting the provisions of paragraph (f) of this 
section, identify the connectors subject to the requirements of this 
subpart. Connectors need not be individually identified if all 
connectors in a designated area or length of pipe subject to the 
provisions of this subpart are identified as a group, and the number of 
connectors subject is indicated.

    Effective Date Note: At 73 FR 31376, June 2, 2008, Sec. 60.482-11a 
was stayed until further notice.

Sec. 60.485a  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
standards in Sec. Sec. 60.482-1a through 60.482-11a, 60.483a, and 
60.484a as follows:
    (1) Method 21 shall be used to determine the presence of leaking 
sources. The instrument shall be calibrated before use each day of its 
use by the procedures specified in Method 21 of appendix A-7 of this 
part. The following calibration gases shall be used:
    (i) Zero air (less than 10 ppm of hydrocarbon in air); and
    (ii) A mixture of methane or n-hexane and air at a concentration no

[[Page 686]]

more than 2,000 ppm 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 ppm 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 
ppm. 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.
    (2) A calibration drift assessment shall be performed, at a minimum, 
at the end of each monitoring day. Check the instrument using the same 
calibration gas(es) that were used to calibrate the instrument before 
use. Follow the procedures specified in Method 21 of appendix A-7 of 
this part, Section 10.1, except do not adjust the meter readout to 
correspond to the calibration gas value. Record the instrument reading 
for each scale used as specified in Sec. 60.486a(e)(7). Calculate the 
average algebraic difference between the three meter readings and the 
most recent calibration value. Divide this algebraic difference by the 
initial calibration value and multiply by 100 to express the calibration 
drift as a percentage. If any calibration drift assessment shows a 
negative drift of more than 10 percent from the initial calibration 
value, then all equipment monitored since the last calibration with 
instrument readings below the appropriate leak definition and above the 
leak definition multiplied by (100 minus the percent of negative drift/
divided by 100) must be re-monitored. If any calibration drift 
assessment shows a positive drift of more than 10 percent from the 
initial calibration value, then, at the owner/operator's discretion, all 
equipment since the last calibration with instrument readings above the 
appropriate leak definition and below the leak definition multiplied by 
(100 plus the percent of positive drift/divided by 100) may be re-
monitored.
    (c) The owner or operator shall determine compliance with the no-
detectable-emission standards in Sec. Sec. 60.482-2a(e), 60.482-3a(i), 
60.482-4a, 60.482-7a(f), and 60.482-10a(e) as follows:
    (1) The requirements of paragraph (b) shall apply.
    (2) Method 21 of appendix A-7 of this part shall be used to 
determine the background level. All potential leak interfaces shall be 
traversed as close to the interface as possible. The arithmetic 
difference between the maximum concentration indicated by the instrument 
and the background level is compared with 500 ppm for determining 
compliance.
    (d) The owner or operator shall test each piece of equipment unless 
he demonstrates that a process unit is not in VOC service, i.e., that 
the VOC content would never be reasonably expected to exceed 10 percent 
by weight. For purposes of this demonstration, the following methods and 
procedures shall be used:
    (1) Procedures that conform to the general methods in ASTM E260-73, 
91, or 96, E168-67, 77, or 92, E169-63, 77, or 93 (incorporated by 
reference--see Sec. 60.17) shall be used to determine the percent VOC 
content in the process fluid that is contained in or contacts a piece of 
equipment.
    (2) Organic compounds that are considered by the Administrator to 
have negligible photochemical reactivity may be excluded from the total 
quantity of organic compounds in determining the VOC content of the 
process fluid.
    (3) Engineering judgment may be used to estimate the VOC content, if 
a piece of equipment had not been shown previously to be in service. If 
the Administrator disagrees with the judgment, paragraphs (d)(1) and (2) 
of this section shall be used to resolve the disagreement.
    (e) The owner or operator shall demonstrate that a piece of 
equipment is in light liquid service by showing that all the following 
conditions apply:
    (1) The vapor pressure of one or more of the organic components is 
greater than 0.3 kPa at 20 [deg]C (1.2 in. H2O at 68 [deg]F). 
Standard reference texts or ASTM D2879-83, 96, or 97 (incorporated by 
reference--see Sec. 60.17) shall be used to determine the vapor 
pressures.
    (2) The total concentration of the pure organic components having a

[[Page 687]]

vapor pressure greater than 0.3 kPa at 20 [deg]C (1.2 in. H2O 
at 68 [deg]F) is equal to or greater than 20 percent by weight.
    (3) The fluid is a liquid at operating conditions.

this section shall be representative of the process fluid that is 
contained in or contacts the equipment or the gas being combusted in the 
flare.

standards of flares as follows:
    (1) Method 22 of appendix A-7 of this part shall be used to 
determine visible emissions.
    (2) A thermocouple or any other equivalent device shall be used to 
monitor the presence of a pilot flame in the flare.
    (3) The maximum permitted velocity for air assisted flares shall be 
computed using the following equation:

Vmax = K1 + K2HT

Where:

Vmax = Maximum permitted velocity, m/sec (ft/sec).
HT = Net heating value of the gas being combusted, MJ/scm 
          (Btu/scf).
K1 = 8.706 m/sec (metric units) = 28.56 ft/sec (English 
          units).
K2 = 0.7084 m\4\/(MJ-sec) (metric units) = 0.087 ft\4\/(Btu-
          sec) (English units).

    (4) The net heating value (HT) of the gas being combusted in a flare 
shall be computed using the following equation:

[GRAPHIC] [TIFF OMITTED] TR16NO07.038

Where:

K = Conversion constant, 1.740 x 10-7 (g-mole)(MJ)/(ppm-scm-
          kcal) (metric units) = 4.674 x 10-6 [(g-mole)(Btu)/
          (ppm-scf-kcal)] (English units).
Ci = Concentration of sample component ``i,'' ppm
Hi = net heat of combustion of sample component ``i'' at 25 
          [deg]C and 760 mm Hg (77 [deg]F and 14.7 psi), kcal/g-mole.

    (5) Method 18 of appendix A-6 of this part or ASTM D6420-99 (2004) 
(where the target compound(s) are those listed in Section 1.1 of ASTM 
D6420-99, and the target concentration is between 150 parts per billion 
by volume and 100 ppmv) and ASTM D2504-67, 77, or 88 (Reapproved 1993) 
(incorporated by reference-see Sec. 60.17) shall be used to determine 
the concentration of sample component ``i.''
    (6) ASTM D2382-76 or 88 or D4809-95 (incorporated by reference-see 
Sec. 60.17) shall be used to determine the net heat of combustion of 
component ``i'' if published values are not available or cannot be 
calculated.
    (7) Method 2, 2A, 2C, or 2D of appendix A-7 of this part, as 
appropriate, shall be used to determine the actual exit velocity of a 
flare. If needed, the unobstructed (free) cross-sectional area of the 
flare tip shall be used.
    (h) The owner or operator shall determine compliance with Sec. 
60.483-1a or Sec. 60.483-2a as follows:
    (1) The percent of valves leaking shall be determined using the 
following equation:

%VL = (VL / VT) * 100

Where:

%VL = Percent leaking valves.
VL = Number of valves found leaking.
VT = The sum of the total number of valves monitored.

    (2) The total number of valves monitored shall include difficult-to-
monitor and unsafe-to-monitor valves only during the monitoring period 
in which those valves are monitored.
    (3) The number of valves leaking shall include valves for which 
repair has been delayed.
    (4) Any new valve that is not monitored within 30 days of being 
placed in service shall be included in the number of valves leaking and 
the total number of valves monitored for the monitoring period in which 
the valve is placed in service.
    (5) If the process unit has been subdivided in accordance with Sec. 
60.482-7a(c)(1)(ii), the sum of valves found leaking during a monitoring 
period includes all subgroups.
    (6) The total number of valves monitored does not include a valve 
monitored to verify repair.

Sec. 60.490  Applicability and designation of affected facility.

    (a) The provisions of this subpart apply to the following affected 
facilities in beverage can surface coating lines: each exterior base 
coat operation, each overvarnish coating operation, and each inside 
spray coating operation.
    (b) The provisions of this subpart apply to each affected facility 
which is identified in paragraph (a) of this section and commences 
construction, modification, or reconstruction after November 26, 1980.



Sec. 60.491  Definitions.

    (a) All terms which are used in this subpart and are not defined 
below are given the same meaning as in the Act and subpart A of this 
part.

which soft drinks or beer, including malt liquor, are packaged. The 
definition does not include containers in which fruit or vegetable 
juices are packaged.
    (2) Exterior base coating operation means the system on each 
beverage can surface coating line used to apply a coating to the 
exterior of a two-piece beverage can body. The exterior base coat 
provides corrosion resistance and a background for lithography or 
printing operations. The exterior base coat operation consists of the 
coating application station, flashoff area, and curing oven. The 
exterior base coat may be pigmented or clear (unpigmented).
    (3) Inside spray coating operation means the system on each beverage 
can surface coating line used to apply a coating to the interior of a 
two-piece beverage can body. This coating provides a protective film 
between the contents of the beverage can and the metal can body. The 
inside spray coating operation consists of the coating application 
station, flashoff area, and curing oven. Multiple applications of an 
inside spray coating are considered to be a single coating operation.

can surface coating line used to apply a coating over ink which reduces 
friction for automated beverage can filling equipment, provides gloss, 
and protects the finished beverage can body from abrasion and corrosion. 
The overvarnish coating is applied to two-piece beverage can bodies. The 
overvarnish coating operation consists of the coating application 
station, flashoff area, and curing oven.

[[Page 694]]

for the performance test providing control device and capture system 
operating conditions have not changed. The procedure in paragraphs 
(b)(2)(i), (A), (B), and (C) of this section, shall be repeated when 
directed by the Administrator or when the owner or operator elects to 
operate the control device or capture system at conditions different 
from the initial performance test.

the owner or operator shall include in the initial performance test 
required under Sec. 60.8(a) the combustion temperature (or the gas 
temperature upstream and downstream of the catalyst bed), the total mass 
of VOC per volume of coating solids before and after the incinerator, 
capture efficiency, and the destruction efficiency of the incinerator 
used to attain compliance with the applicable emission limit specified 
under Sec. 60.492. The owner or operator shall also include a 
description of the method used to establish the amount of VOC captured 
by the capture system and sent to the control device.
    (b) Following the initial performance test, each owner or operator 
shall identify, record, and submit quarterly reports to the 
Administrator of each instance in which the volume-weighted average of 
the total mass of VOC per volume of coating solids, after the control 
device, if capture devices and control systems are used, is greater than 
the limit specified under Sec. 60.492. If no such instances occur 
during a particular quarter, a report stating this shall be submitted to 
the Administrator semiannually.
    (c) Following the initial performance test, the owner or operator of 
an affected facility shall identify, record, and submit at the frequency 
specified in Sec. 60.7(c) the following:
    (1) Where compliance with Sec. 60.492 is achieved through the use 
of thermal incineration, each 3-hour period when cans are processed, 
during which the average temperature of the device was more than 28 
[deg]C below the average temperature of the device during the most 
recent performance test at which destruction efficiency was determined 
as specified under Sec. 60.493.
    (2) Where compliance with Sec. 60.492 is achieved through the use 
of catalytic incineration, each 3-hour period when cans are being 
processed, during which the average temperature of the device 
immediately before the catalyst bed is more than 28 [deg]C below the 
average temperature of the device immediately before the catalyst bed 
during the most recent performance test at which destruction efficiency 
was determined as specified under Sec. 60.493 and all 3-hour

[[Page 696]]

periods, when cans are being processed, during which the average 
temperature difference across the catalyst bed is less than 80 percent 
of the average temperature difference across the catalyst bed during the 
most recent performance test at which destruction efficiency was 
determined as specified under Sec. 60.494.
    (3) For thermal and catalytic incinerators, if no such periods as 
described in paragraphs (c)(1) and (c)(2) of this section occur, the 
owner or operator shall state this in the report.
    (d) Each owner or operator subject to the provisions of this subpart 
shall maintain at the source, for a period of at least 2 years, records 
of all data and calculations used to determine VOC emissions from each 
affected facility in the initial and monthly performance tests. Where 
compliance is achieved through the use of thermal incineration, each 
owner or operator shall maintain, at the source, daily records of the 
incinerator combustion chamber temperature. If catalytic incineration is 
used, the owner or operator shall maintain at the source daily records 
of the gas temperature, both upstream and downstream of the incinerator 
catalyst bed. Where compliance is achieved through the use of a solvent 
recovery system, the owner or operator shall maintain at the source 
daily records of the amount of solvent recovered by the system for each 
affected facility.
    (e) The requirements of this section remain in force until and 
unless EPA, in delegating enforcement authority to a State under section 
111(c) of the Act, approves reporting requirements or an alternative 
means of compliance surveillance adopted by such State. In that event, 
affected facilities within the State will be relieved of the obligation 
to comply with this subsection, provided that they comply with the 
requirements established by the State.

Sec. 60.496  Test methods and procedures.

    (a) The reference methods in appendix A to this part, except as 
provided in Sec. 60.8, shall be used to conduct performance tests.
    (1) Method 24, an equivalent or alternative method approved by the 
Administrator, or manufacturers' formulation data from which the VOC 
content of the coatings used for each affected facility can be 
calculated. In the event of a dispute, Method 24 data shall govern. When 
VOC content of water-borne coatings, determined from data generated by 
Method 24, is used to determine compliance of affected facilities, the 
results of the Method 24 analysis shall be adjusted as described in 
Section 12.6 of Method 24.
    (2) Method 25 or an equivalent or alternative method for the 
determination of the VOC concentration in the effluent gas entering and 
leaving the control device for each stack equipped with an emission 
control device. The owner or operator shall notify the Administrator at 
least 30 days in advance of any State test using Method 25. The 
following reference methods are to be used in conjunction with Method 
25:
    (i) Method 1 for sample and velocity traverses,
    (ii) Method 2 for velocity and volumetric flow rate,
    (iii) Method 3 for gas analysis, and
    (iv) Method 4 for stack gas moisture.
    (b) For Method 24, the coating sample must be a 1-litre sample 
collected in a 1-litre container at a point where the sample will be 
representative of the coating material.
    (c) For Method 25, the sampling time for each of three runs must be 
at least 1 hour. The minimum sample volume must be 0.003 dscm except 
that shorter sampling times or smaller volumes, when necessitated by 
process variables or other factors, may be approved by the 
Administrator. The Administrator will approve the sampling of 
representative stacks on a case-by-case basis if the owner or operator 
can demonstrate to the satisfaction of the Administrator that the 
testing of representative stacks would yield results comparable to those 
that would be obtained by testing all stacks.
