the EPA is not revising the emission limit requirements. The EPA is
revising the SSM provisions of the rule and requiring the use of
electronic data reporting for future performance test data submittals,
notifications, and reports. This information is being collected to
assure compliance with 40 CFR part 63, subpart SSSS.
    Respondents/affected entities: Facilities performing surface
coating of metal coil.
    Respondent's obligation to respond: Mandatory (40 CFR part 63,
subpart SSSS).
    Estimated number of respondents: In the 3 years after the
amendments are finalized, approximately 48 respondents per year will be
subject to the NESHAP and no additional respondents are expected to
become subject to the NESHAP during that period.
    Frequency of response: The total number of responses in year 1 is
144 and in year 3 is 69. Year 2 would have no responses.
    Total estimated burden: The average annual burden to the 48 metal
coil coating facilities over the 3 years after the amendments are
finalized is estimated to be 738 hours (per year). The average annual
burden to the Agency over the 3 years after the amendments are
finalized is estimated to be 179 hours (per year). Burden is defined at
5 CFR 1320.3(b).
    Total estimated cost: The average annual cost to the 48 metal coil
coating facilities is estimated to be $85,000 in labor costs and
$186,000 in capital and O&M costs in the first 3 years after the
amendments are finalized. The average annual Agency cost over the first
3 years after the amendments are finalized is estimated to be $8,530.
    An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for the
EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB
approves the ICRs, the Agency will announce that approval in the
Federal Register and publish a technical amendment to 40 CFR part 9 to
display the OMB control number for the approved information collection
actions contained in the final rule.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. The
eleven small entities that are subject to the requirements of this
action are small businesses. The Agency has determined that the seven
ultimate owners of these eleven affected small entities (21 percent of
the facilities affected by this action) so impacted may experience an
impact of 0.0029 to 0.77 percent of annual sales revenues per ultimate
owner. Details of this analysis are described in section V.D above and
in the economic impact memorandums located in the dockets for this
action.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or
more as described in UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. The action imposes
no enforceable duty on any state, local, or tribal governments or the
private sector.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.

G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action does not have tribal implications as specified in
Executive Order 13175. No tribal facilities are known to be engaged in
any of the industries that would be affected by this action (metal can
surface coating and metal coil surface coating). Thus, Executive Order
13175 does not apply to this action.

H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because the EPA does not believe the environmental health or safety
risks addressed by this action present a disproportionate risk to
children. This action's health and risk assessments are contained in
sections III.A and C, IV.A.1 and 2, IV.B.1 and 2, and IV.C.1 and 2 of
the proposal preamble (84 FR 25904, June 4, 2019) and are further
documented in the Residual Risk Assessment for the Surface Coating of
Metal Cans Source Category in Support of the 2019 Risk and Technology
Review Proposed Rule and the Residual Risk Assessment for the Surface
Coating of Metal Coil Source Category in Support of the 2019 Risk and
Technology Review Proposed Rule in the Surface Coating of Metal Cans
Docket and the Surface Coating of Metal Coil Docket, respectively.

I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 because it is
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR
Part 51

    This rulemaking involves technical standards. The EPA amended the
Surface Coating of Metal Coil NESHAP in this action to provide owners
and operators with the option of conducting two new methods: EPA Method
18 of appendix A to 40 CFR part 60, ``Measurement of Gaseous Organic
Compound Emissions by Gas Chromatography,'' to measure and subtract
methane emissions from measured total gaseous organic mass emissions as
carbon, and ASTM Method D1475-13, ``Standard Test Method for Density of
Liquid Coatings, Inks, and Related Products.'' We are incorporating
ASTM Method D1475-13 by reference. We are adding these two standards to
the Surface Coating of Metal Coil NESHAP only, as these methods are
already provided in the Surface Coating of Metal Cans NESHAP.
    The EPA is also amending the Surface Coating of Metal Cans NESHAP
to update three ASTM test methods and

amend the Surface Coating of Metal Coil NESHAP to update two ASTM test
methods. We are updating ASTM Method D1475-90, ``Standard Test Method
for Density of Liquid Coatings, Inks, and Related Products,'' in the
Surface Coating of Metal Cans NESHAP by incorporating by reference ASTM
Method D1475-13. The updated version, ASTM Method D1475-13, clarifies
units of measure and reduces the number of determinations required. We
are updating ASTM Method D2697-86 (1998), ``Standard Test Method for
Volume Nonvolatile Matter in Clear or Pigmented Coatings,'' in both the
Surface Coating of Metal Cans and the Surface Coating of Metal Coil
NESHAP by incorporating by reference ASTM D2697-03 (2014), which is the
updated version of the previously approved method. We are also updating
ASTM Method D6093-97 (2003), ``Standard Test Method for Percent Volume
Nonvolatile Matter in Clear or Pigmented Coatings Using Helium Gas
Pycnometer,'' in both the Surface Coating of Metal Cans and the Surface
Coating of Metal Coil NESHAP by incorporating by reference ASTM D6093-
97 (2016), which is the updated version of the previously approved
method. ASTM D2697-03 (2014) is a test method that can be used to
determine the volume of nonvolatile matter in clear and pigmented
coatings and ASTM D6093-97 (2016) is a test method that can be used to
determine the percent volume of nonvolatile matter in clear and
pigmented coatings.
    For the Surface Coating of Metal Cans NESHAP and the Surface
Coating of Metal Coil NESHAP, we are incorporating by reference ASTM
D2369-10 (2015), ``Test Method for Volatile Content of Coatings,'' as
an alternative to EPA Method 24 for the determination of the volatiles
emitted by the surface coatings. The test method determines the weight
percent volatile content of solvent borne and water borne coatings
under specified test conditions. It is viable for coatings wherein one
or more parts may, at ambient conditions, contain liquid co-reactants
that are volatile until a chemical reaction has occurred with another
component of a multi-package system.
    For the Surface Coating of Metal Cans and the Surface Coating of
Metal Coil NESHAP, we are incorporating by reference ASTM D2111-10
(2015), ``Standard Test Methods for Specific Gravity and Density of
Halogenated Organic Solvents and Their Admixtures,'' for the
determination of the specific gravity of halogenated organic solvents
and solvent admixtures in surface coatings. ASTM D2111-10 (2015)
includes three test methods to measure specific gravity using suitable
apparatus (i.e., a hydrometer, a pycnometer, or an electronic
densitometer), procedures, and details underlying the interpretation of
test data and the selection of numerical limits.
    The ASTM standards are available from the American Society for
Testing and Materials (ASTM), 100 Barr Harbor Drive, Post Office Box
C700, West Conshohocken, PA 19428-2959. See http://www.astm.org/.
    The EPA decided not to include certain other VCS; these methods are
impractical as alternatives because of the lack of equivalency,
documentation, validation date, and other important technical and
policy considerations. The search and review results have been
documented and are in the memoranda titled Voluntary Consensus Standard
Results for Surface Coating of Metal Cans, August 16, 2018, and
Voluntary Consensus Standard Results for Surface Coating of Metal Coil,
August 16, 2018, in the Surface Coating of Metal Cans Docket and the
Surface Coating of Metal Coil Docket, respectively.
    Under 40 CFR 63.7(f) and 40 CFR 63.8(f) of subpart A of the General
Provisions, a source may apply to the EPA for permission to use
alternative test methods or alternative monitoring requirements in
place of any required testing methods, performance specifications, or
procedures in the final rule or any amendments.

K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes that this action does not have disproportionately
high and adverse human health or environmental effects on minority
populations, low-income populations, and/or indigenous peoples, as
specified in Executive Order 12898 (59 FR 7629, February 16, 1994)
because it does not significantly affect the level of protection
provided to human health or the environment. The documentation for this
decision is contained in section IV of this preamble and the technical
reports titled Risk and Technology Review--Analysis of Demographic
Factors for Populations Living Near Surface Coating of Metal Cans
Source Category Operations, May 2018, and Risk and Technology Review--
Analysis of Demographic Factors for Populations Living Near Surface
Coating of Metal Coil Source Category Operations, May 2018, which are
available in the Surface Coating of Metal Cans and Surface Coating of
Metal Coil Dockets, respectively.

L. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is not a ``major rule'' as defined by 5
U.S.C. 804(2)

to Sec.  63.3541(i), you must meet the operating limits specified in
Table 4 to this subpart. Those operating limits apply to the emission
capture and control systems for the coating operation(s) used for
purposes of complying with this subpart. You must establish the
operating limits during the performance tests required in Sec.  63.3540
or Sec.  63.3550 according to the requirements in Sec.  63.3546 or
Sec.  63.3556. You must meet the operating limits established during

5. Section 63.3500 is amended by revising paragraphs (a)(1), (b), and
(c) to read as follows:

Sec.  63.3500  What are my general requirements for complying with this
subpart?

    (a) * * *
    (1) Any coating operation(s) for which you use the compliant
material option or the emission rate without add-on controls option, as
specified in Sec.  63.3491(a) and (b), must be in compliance with the
applicable emission limit in Sec.  63.3490 at all times.
* * * * *
    (b) Before August 24, 2020, you must always operate and maintain
your affected source, including all air pollution control and
monitoring equipment you use for purposes of complying with this
subpart, according to the provisions in Sec.  63.6(e)(1)(i). On and
after August 24, 2020, at all times, the owner or operator must operate
and maintain any affected source, including associated air pollution
control equipment and monitoring equipment, in a manner consistent with
safety and good air pollution control practices for minimizing
emissions. The general duty to minimize emissions does not require the
owner or operator to make any further efforts to reduce emissions if
levels required by the applicable standard have been achieved.
Determination of whether a source is operating in compliance with
operation and maintenance requirements will be based on information
available to the Administrator that may include, but is not limited to,
monitoring results, review of operation and maintenance procedures,
review of operation and maintenance records, and inspection of the
affected source.
    (c) Before August 24, 2020, if your affected source uses an
emission capture system and add-on control device for purposes of
complying with this subpart, you must develop a written startup,
shutdown, and malfunction plan (SSMP) according to the provisions in
Sec.  63.6(e)(3). The plan must address startup, shutdown, and
corrective actions in the event of a malfunction of the emission
capture system or the add-on control device. The plan must also address
any coating operation equipment that may cause increased emissions or
that would affect capture efficiency if the process equipment
malfunctions, such as conveyors that move parts among enclosures. On
and after August 24, 2020, the SSMP is not required.

    (g) If you are required to electronically submit a report through
the CEDRI in the EPA's CDX, you may assert a claim of the EPA system
outage for failure to timely comply with the reporting requirement. To
assert a claim of the EPA system outage, you must meet the requirements
outlined in paragraphs (g)(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.
    (2) The outage must have occurred within the period of time
beginning five business days prior to the date that the submission is
due.
    (3) The outage may be planned or unplanned.
    (4) 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 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 the EPA system outage;
    (iii) 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 the 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.
    (h) If you are required to electronically submit a report through
CEDRI in the EPA's CDX, you may assert a claim of force majeure for
failure to timely comply with the reporting requirement. To assert a
claim of force majeure, you must meet the requirements outlined in
paragraphs (h)(1) through (5) of this section.
    (1) 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).
    (2) 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.
    (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) 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.

9. Section 63.3521 is amended by revising paragraphs (a)(1)(i), (a)(2),
(a)(4), (b)(1), and (c) to read as follows:

Sec.  63.3521  How do I demonstrate initial compliance with the
emission limitations?

* * * * *
    (a) * * *
    (1) * * *
    (i) Count each organic HAP in Table 8 to this subpart that is
measured to be present at 0.1 percent by mass or more and at 1.0
percent by mass or more for other compounds. For example, if toluene
(not listed in Table 8 to this subpart) is measured to be 0.5 percent
of the material by mass, you do not have to count it. Express the mass
fraction of each organic HAP you count as a value truncated to four
places after the decimal point (e.g., 0.3791).
* * * * *
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may
use Method 24 to determine the mass fraction of nonaqueous volatile
matter and use that value as a substitute for mass fraction of organic
HAP. As an alternative to using Method 24, you may use ASTM D2369-10
(2015), ``Test Method for Volatile Content of Coatings'' (incorporated
by reference, see Sec.  63.14).
* * * * *
    (4) 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 (a)(1) through (3) of this section,
such as manufacturer's formulation data, if it represents each organic
HAP in Table 8 to this subpart that is present at 0.1 percent by mass
or more and at 1.0 percent by mass or more for other compounds. For
example, if toluene (not listed in Table 8 to this subpart) is 0.5
percent of the material by mass, you do not have to count it. If there
is a disagreement between such information and results of a test
conducted according to paragraphs (a)(1) through (3) of this section,
then the test method results will take precedence unless, after
consultation, a regulated source can demonstrate to the satisfaction of
the enforcement agency that the formulation data are correct.
* * * * *
    (b) * * *
    (1) ASTM Method D2697-03 (2014) or D6093-97 (2016). You may use
ASTM D2697-03 (2014), ``Standard Test Method for Volume Nonvolatile
Matter in Clear or Pigmented Coatings,'' (incorporated by reference,
see Sec.  63.14) or ASTM D6093-97 (2016), ``Standard Test Method for
Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using
a Helium Gas Pycnometer'' (incorporated by reference, see Sec.  63.14),
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. If these values cannot
be determined using these methods, the owner/operator may submit an
alternative technique for determining the values for approval by the
Administrator.
* * * * *
    (c) Determine the density of each coating. Determine the density of
each coating used during the compliance period from test results using
ASTM Method D1475-13 ``Standard Test Method for Density of Liquid
Coatings, Inks, and Related Products'' (incorporated by reference, see
Sec.  63.14) or information from the supplier or manufacturer of the
material. If there is disagreement between ASTM Method D1475-13 test
results and the supplier's or manufacturer's information, the test
results will take precedence.

10. Section 63.3531 is amended by revising paragraph (c) to read as
follows:

Sec.  63.3531  How do I demonstrate initial compliance with the
emission limitations?

* * * * *
    (c) Determine the density of each material. Determine the density
of each coating and thinner used during each month from test results
using ASTM D1475-13 or ASTM D2111-10 (2015) (both incorporated by
reference, see Sec.  63.14), information from the supplier or
manufacturer of the material, or reference sources providing density or
specific gravity data for pure materials. If there is disagreement
between ASTM D1475-13 or ASTM D2111-10 (2015) test results and such
other information sources, the test results will take precedence.

11. Section 63.3540 is amended by revising the section heading and
paragraphs (a)(1), (a)(4), and (b)(1) to read as follows:

Sec.  63.3540  By what date must I conduct performance tests and
initial compliance demonstrations?

    (a) * * *
    (1) All emission capture systems, add-on control devices, and CPMS
must be installed and operating no later than the applicable compliance
date specified in Sec.  63.3483. Except for solvent recovery systems
for which you conduct liquid-liquid material balances according to
Sec.  63.3541(i), you must conduct according to the schedule in
paragraphs (a)(1)(i) and (ii) of this section initial and periodic
performance tests of each capture system and add-on control device
according to the procedures in Sec. Sec.  63.3543, 63.3544, and 63.3545
and establish the operating limits required by Sec.  63.3492. For a
solvent recovery system for which you conduct liquid-liquid material
balances according to Sec.  63.3541(i), you must initiate the first
material balance no later than the applicable compliance date specified
in Sec.  63.3483.
    (i) You must conduct the initial performance test and establish the
operating limits required by Sec.  63.3492 no later than 180 days after
the applicable compliance date specified in Sec.  63.3483.
    (ii) If you are not required to complete periodic performance tests
as a requirement of renewing your facility's

operating permit under 40 CFR part 70 or 40 CFR part 71, you must
conduct the first periodic performance test before March 25, 2023,
unless you already have conducted a performance test on or after March
25, 2018. 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
required to complete periodic performance tests as a requirement of
renewing your facility's operating permit under 40 CFR part 70 or 40
CFR part 71, you must conduct the periodic testing in accordance with
the terms and schedule required by your permit conditions.
* * * * *
    (4) For the initial compliance demonstration, you do not need to
comply with the operating limits for the emission capture system and
add-on control device required by Sec.  63.3492 until after you have
completed the initial performance tests specified in paragraph (a)(1)
of this section. Instead, you must maintain a log detailing the
operation and maintenance of the emission capture system, add-on
control device, and continuous parameter monitors during the period
between the compliance date and the performance test. You must begin
complying with the operating limits established based on the initial
performance tests specified in paragraph (a)(1) of this section for
your affected source on the date you complete the performance tests.
The requirements in this paragraph (a)(4) do not apply to solvent
recovery systems for which you conduct liquid-liquid material balances
according to the requirements in Sec.  63.3541(i).
    (b) * * *
    (1) All emission capture systems, add-on control devices, and CPMS
must be installed and operating no later than the applicable compliance
date specified in Sec.  63.3483. Except for solvent recovery systems
for which you conduct liquid-liquid material balances according to
Sec.  63.3541(i), you must conduct according to the schedule in
paragraphs (b)(1)(i) and (ii) of this section initial and periodic
performance tests of each capture system and add-on control device
according to the procedures in Sec. Sec.  63.3543, 63.3544, and 63.3545
and establish the operating limits required by Sec.  63.3492. For a
solvent recovery system for which you conduct liquid-liquid material
balances according to Sec.  63.3541(i), you must initiate the first
material balance no later than the compliance date specified in Sec.
63.3483.
    (i) You must conduct the initial performance test and establish the
operating limits required by Sec.  63.3492 no later than 180 days after
the applicable compliance date specified in Sec.  63.3483.
    (ii) If you are not required to complete periodic performance tests
as a requirement of renewing your facility's operating permit under 40
CFR part 70 or 40 CFR part 71, you must conduct the first periodic
performance test before March 25, 2023, unless you already have
conducted a performance test on or after March 25, 2018. 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 required to
complete periodic performance tests as a requirement of renewing your
facility's operating permit under 40 CFR part 70 or 40 CFR part 71, you
must conduct the periodic testing in accordance with the terms and
schedule required by your permit conditions.

12. Section 63.3541 is amended by revising paragraphs (h) introductory
text and (i)(3) to read as follows:

Sec.  63.3541  How do I demonstrate initial compliance?

* * * * *
    (h) Calculate the organic HAP emission reduction for each
controlled coating operation not using liquid-liquid material balances.
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, calculate the
organic HAP emission reduction, using Equation 1 of this section. The
calculation applies the emission capture system efficiency and add-on
control device efficiency to the mass of organic HAP contained in the
coatings and thinners that are used in the coating operation served by
the emission capture system and add-on control device during each
month. For any period of time a deviation specified in Sec.  63.3542(c)
or (d) occurs in the controlled coating operation, you must assume zero
efficiency for the emission capture system and add-on control device,
unless you have other data indicating the actual efficiency of the
emission capture system and add-on control device, and the use of these
data has been approved by the Administrator. Equation 1 of this section
treats the materials used during such a deviation as if they were used
on an uncontrolled coating operation for the time period of the
deviation.
* * * * *
    (i) * * *
    (3) Determine the mass fraction of volatile organic matter for each
coating and thinner used in the coating operation controlled by the
solvent recovery system during the month, in kg volatile organic matter
per kg coating. You may determine the volatile organic matter mass
fraction using Method 24 of 40 CFR part 60, appendix A, ASTM D2369-10
(2015), ``Test Method for Volatile Content of Coatings'' (incorporated
by reference, see Sec.  63.14), or an EPA approved alternative method.
Alternatively, you may determine the volatile organic matter mass
fraction using information provided by the manufacturer or supplier of
the coating. In the event of any inconsistency between information
provided by the manufacturer or supplier and the results of Method 24
of 40 CFR part 60, appendix A, ASTM D2369-10 (2015) or an approved
alternative method, the test method results will take precedence
unless, after consultation, a regulated source can demonstrate to the
satisfaction of the enforcement agency that the formulation data are
correct.

13. Section 63.3542 is amended by revising paragraphs (f) and (h) to
read as follows:

Sec.  63.3542  How do I demonstrate continuous compliance with the
emission limitations?

* * * * *
    (f) As part of each semiannual compliance report required in Sec.
63.3511, you must identify the coating operation(s) for which you used
the emission rate with add-on controls option. If there were no
deviations from the emission limits in Sec.  63.3490, the operating
limits in Sec.  63.3492, and the work practice standards in Sec.
63.3493, submit a statement that you were in compliance with the
emission limitations during the reporting period because the organic
HAP emission rate for each compliance period was less than or equal to
the applicable emission limit in Sec.  63.3490, and you achieved the
operating limits required by Sec.  63.3492 and the work practice
standards required by Sec.  63.3493 during each compliance period.
* * * * *
    (h) Before August 24, 2020, consistent with Sec. Sec.  63.6(e) and
63.7(e)(1), deviations that occur during a period of startup, shutdown,
or malfunction of the emission capture system, add-on control device,
or coating operation that may

affect emission capture or control device efficiency are not violations
if you demonstrate to the Administrator's satisfaction that you were
operating in accordance with Sec.  63.6(e)(1). The Administrator will

17. Section 63.3546 is amended by revising the introductory text and
paragraphs (a)(1) and (2), (b)(1) through (3), (d)(1), (e)(1) and (2),
(f)(1) through (3), and (f)(5) and (6) to read as follows:

Sec.  63.3546  How do I establish the emission capture system and add-
on control device operating limits during the performance test?

    During performance tests required by Sec.  63.3540 and described in
Sec. Sec.  63.3543, 63.3544, and 63.3545, you must establish the
operating limits required by Sec.  63.3492 unless you have received
approval for alternative monitoring and operating limits under Sec.
63.8(f) as specified in Sec.  63.3492.
    (a) * * *
    (1) During performance tests, 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) For each performance test, use the data collected during the
performance test to calculate and record the average combustion
temperature maintained during the performance test. That average
combustion temperature is the minimum operating limit for your thermal
oxidizer.
    (b) * * *
    (1) During performance tests, you must monitor and record the
temperature at the inlet to 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) For each performance test, use the data collected during the
performance test to calculate and record the average temperature at the
inlet to the catalyst bed and the average temperature difference across
the catalyst bed maintained during the performance test. The average
temperature difference is the minimum operating limit for your
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 performance tests, you must monitor and
record the temperature at the inlet to the catalyst bed at least once
every 15 minutes during each of the three test runs. For each
performance test, use the data collected during the performance test to
calculate and record the average temperature at the inlet to the
catalyst bed during the performance test. That is the minimum operating
limit for your catalytic oxidizer.
* * * * *
    (d) * * *
    (1) During performance tests, 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.
* * * * *

    (e) * * *
    (1) During performance tests, monitor and record the condenser
outlet (product side) gas temperature at least once every 15 minutes
during each of the three test runs of the performance test.
    (2) For each performance test, use the 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 operating
limit for your condenser.
    (f) * * *
    (1) During performance tests, monitor and record the inlet
temperature to the desorption/reactivation zone of the concentrator at
least once every 15 minutes during each of the three runs of the
performance test.
    (2) For each performance test, use the data collected during the
performance test to calculate and record the average temperature. This
is the minimum operating limit for the desorption/reactivation zone
inlet temperature.
    (3) During each performance test, monitor and record an
indicator(s) of performance for the desorption/reactivation fan
operation at least once every 15 minutes during each of the three runs
of the performance test. The indicator can be speed in revolutions per
minute (rpm), power in amps, static pressure, or flow rate.
* * * * *
    (5) During each performance test, monitor the rotational speed of
the concentrator at least once every 15 minutes during each of the
three runs of the performance test.
    (6) For each performance test, use the data collected during the
performance test to calculate and record the average rotational speed.
This is the minimum operating limit for the rotational speed of the
concentrator. However, the indicator range for the rotational speed may
be changed if an engineering evaluation is conducted and a
determination made that the change in speed will not affect compliance
with the emission limit.

(a)(7), and (c)(3) introductory text to read as follows:

Sec.  63.3547  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) * * *
    (4) Before August 24, 2020, you must maintain the CPMS at all times
and have available necessary parts for routine repairs of the
monitoring equipment. On and after August 24, 2020, you must maintain
the CPMS at all times in accordance with Sec.  63.3500(b) and keep
necessary parts readily available for routine repairs of the monitoring
equipment.
    (5) Before August 24, 2020, you must operate the CPMS and collect
emission capture system and add-on control device parameter data at all
times that a controlled coating operation is operating, except during
monitoring malfunctions, associated repairs, and required quality
assurance or control activities (including, if applicable, calibration
checks and required zero and span adjustments). On and after August 24,
2020, you must operate the CPMS and collect emission capture system and
add-on control device parameter data at all times in accordance with
Sec.  63.3500(b).
* * * * *
    (7) A monitoring malfunction is any sudden, infrequent, not
reasonably preventable failure of the CPMS to provide valid data.
Monitoring failures that are caused, in part, by poor maintenance or
careless operation are not malfunctions. Before August 24, 2020, any
period for which the monitoring system is out of control and data are
not available for required calculations is a deviation from the
monitoring requirements. On and after August 24, 2020, except for
periods of required quality assurance or control activities, any period
for which the CPMS fails to operate and record data continuously as
required by paragraph (a)(5) of this section, or generates data that
cannot be included in calculating averages as specified in (a)(6) of
this section constitutes a deviation from the monitoring requirements.
* * * * *
    (c) * * *
    (3) For all thermal oxidizers and catalytic oxidizers, you must
meet the requirements in paragraphs (a) and (c)(3)(i) through (ii) of
this section for each gas temperature monitoring device. For the
purposes of this paragraph (c)(3), a thermocouple is part of the
