alternate file with the CBI omitted must be submitted to the EPA via
the EPA's CDX as described in paragraph (d)(1) of this section.
    (e) Beginning on March 15, 2021, the owner or operator shall submit
the initial notifications required in Sec.  63.9(b) and the
notification of compliance status required in Sec.  63.9(h) and Sec.
63.4310(c) to the EPA via CEDRI. The CEDRI interface can be accessed
through the EPA's CDX (https://cdx.epa.gov). The owner or operator must
upload to CEDRI an electronic copy of each applicable notification in
portable document format (PDF). The applicable notification must be
submitted by the deadline specified in this subpart,

regardless of the method in which the reports are submitted. Owners or
operators who claim that some of the information required to be
submitted via CEDRI is CBI shall submit a complete report generated
using the appropriate form in CEDRI or an alternate electronic file
consistent with the extensible markup language (XML) schema listed on
the EPA's CEDRI website, including information claimed to be CBI, on a
compact disc, flash drive, or other commonly used electronic storage
medium to the EPA. The electronic medium shall be clearly marked as CBI
and mailed to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group Leader,
Measurement Policy Group, MD C404-02, 4930 Old Page Rd., Durham, NC
27703. The same file with the CBI omitted shall be submitted to the EPA
via the EPA's CDX as described earlier in this paragraph.
    (f) Beginning on March 15, 2021, or once the reporting template has
been available on the CEDRI website for 1 year, whichever date is
later, the owner or operator shall submit the semiannual compliance
report required in paragraph (a) of this section to the EPA via CEDRI.
The CEDRI interface can be accessed through the EPA's CDX (https://cdx.epa.gov). The owner or operator must use the appropriate electronic
template on the CEDRI website for this subpart or an alternate
electronic file format consistent with the XML schema listed on the
CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The date
report templates become available will be listed on the CEDRI website.
If the reporting form for the semiannual compliance report specific to
this subpart is not available in CEDRI at the time that the report is
due, you must submit the report to the Administrator at the appropriate
addresses listed in Sec.  63.13. Once the form has been available in
CEDRI for 1 year, you must begin submitting all subsequent reports via
CEDRI. The reports must be submitted by the deadlines specified in this
subpart, regardless of the method in which the reports are submitted.
Owners or operators who claim that some of the information required to
be submitted via CEDRI is CBI shall submit a complete report generated
using the appropriate form in CEDRI or an alternate electronic file
consistent with the XML schema listed on the EPA's CEDRI website,
including information claimed to be CBI, on a compact disc, flash
drive, or other commonly used electronic storage medium to the EPA. The
electronic medium shall be clearly marked as CBI and mailed to U.S.
EPA/OAQPS/CORE CBI Office, Attention: Group Leader, Measurement Policy
Group, MD C404-02, 4930 Old Page Rd., Durham, NC 27703. The same file
with the CBI omitted shall be submitted to the EPA via the EPA's CDX as
described earlier in this paragraph.
    (g) If you are required to electronically submit a report through
CEDRI in the EPA's CDX, and due to a planned or actual outage of either
the EPA's CEDRI or CDX systems within the period of time beginning 5
business days prior to the date that the submission is due, you will be
or are precluded from accessing CEDRI or CDX and submitting a required
report within the time prescribed, you may assert a claim of EPA system
outage for failure to timely comply with the reporting requirement. 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. You must provide to the Administrator a written description
identifying the date, time and length of the outage; a rationale for
attributing the delay in reporting beyond the regulatory deadline to
the EPA system outage; describe the measures taken or to be taken to
minimize the delay in reporting; and identify a 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. In any
circumstance, the report must be submitted electronically as soon as
possible after the outage is resolved. 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.
    (h) If you are required to electronically submit a report through
CEDRI in the EPA's CDX and 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 5 business days prior to the
date the submission is due, the owner or operator may assert a claim of
force majeure for failure to timely comply with the reporting
requirement. 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). If you intend to
assert a claim of force majeure, 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. You must provide to the
Administrator a written description of the force majeure event and a
rationale for attributing the delay in reporting beyond the regulatory
deadline to the force majeure event; describe the measures taken or to
be taken to minimize the delay in reporting; and identify a 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. In
any circumstance, the reporting must occur as soon as possible after
the force majeure event occurs. 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.

26. Section 63.4312 is amended by revising paragraphs (i), (j)
introductory text, and (j)(1) and (2) to read as follows:

Sec.  63.4312  What records must I keep?

* * * * *
    (i) Before September 12, 2019, you must keep records of the date,
time, and duration of each deviation. On and after September 12, 2019,
for each deviation from an emission limitation reported under Sec.
63.4311(a)(5) through (8), a record of the information specified in
paragraphs (i)(1) through (4) of this section, as applicable.
    (1) The date, time, and duration of the deviation, as reported
under Sec.  63.4311(a)(5) through (8).
    (2) A list of the affected sources or equipment for which the
deviation occurred and the cause of the deviation, as reported under
Sec.  63.4311(a)(5) through (8).
    (3) An estimate of the quantity of each regulated pollutant emitted
over any applicable emission limit in Table 1 to this subpart or any
applicable operating limit in Table 2 to this subpart, and a
description of the method used to calculate the estimate, as reported
under Sec.  63.4311(a)(5) through (8). If you use the equivalent
emission rate option to comply with this subpart, a record of the
applicable information specified in Sec.  63.4311(a)(8)(ii) through
(iv) satisfies the recordkeeping requirement in this paragraph (i)(3).
    (4) A record of actions taken to minimize emissions in accordance
with Sec.  63.4300(b) and any corrective actions

taken to return the affected unit to its normal or usual manner of
operation.
    (j) If you use the emission rate with add-on controls option, the
organic HAP overall control efficiency option, or the oxidizer outlet
organic HAP concentration option, you must also keep the records
specified in paragraphs (j)(1) through (8) of this section.
    (1) Before September 12, 2019, for each deviation, a record of
whether the deviation occurred during a period of startup, shutdown, or
malfunction. The record in this paragraph (j)(1) is not required on and
after September 12, 2019.
    (2) Before September 12, 2019, the records in Sec.  63.6(e)(3)(iii)
through (v) related to startup, shutdown, and malfunction. The records
in this paragraph (j)(2) are not required on and after September 12,
2019.

27. Section 63.4313 is amended by revising paragraph (a) to read as
follows:

Sec.  63.4313  In what form and for how long must I keep my records?

    (a) Your records must be in a form suitable and readily available
for expeditious review, according to Sec.  63.10(b)(1). Where
appropriate, the records may be maintained as electronic spreadsheets
or as a database. Any records required to be maintained by this subpart
that are in reports that were 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.

28. Section 63.4321 is amended by revising paragraphs (e)(1)(i)(A),
(e)(1)(ii) and (iv), and (e)(2)(i) to read as follows:

Sec.  63.4321  How do I demonstrate initial compliance with the
emission limitations?

* * * * *
    (e) * * *
    (1) * * *
    (i) * * *
    (A) Count each organic HAP in Table 6 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 6 to this subpart) is measured to be 0.5 percent
of the material by mass, you don't have to count it. Express the mass
fraction of each organic HAP you count as a value truncated to no more
than four places after the decimal point (e.g., 0.3791).
* * * * *
    (ii) Method 24 in appendix A-7 of part 60. 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 (R2015),
``Test Method for Volatile Content of Coatings'' (incorporated by
reference, see Sec.  63.14). For a multi-component coating with
reactive chemicals, you may use Method 24 or ASTM D2369-10 (R2015) on
the coating as applied to determine the mass fraction of nonaqueous
volatile matter and use that value as a substitute for the mass
fraction of organic HAP determined from the sum of organic HAP in each
component.
* * * * *
    (iv) 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 (e)(1)(i) through (iii) of this
section, such as manufacturer's formulation data, if it represents each
organic HAP in Table 6 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 6 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 (e)(1)(i) through (iii) of this
section on coating, thinning, or cleaning material, then the test
method results will take precedence. Information from the supplier or
manufacturer of the printing, slashing, dyeing, or finishing material
is sufficient for determining the mass fraction of organic HAP.
* * * * *
    (2) * * *
    (i) Method 24 in appendix A-7 of part 60. You may use Method 24 for
determining the mass fraction of solids of coating materials. As an
alternative to using Method 24, you may use ASTM D2369-10 (R2015),
``Test Method for Volatile Content of Coatings'' (incorporated by
reference, see Sec.  63.14).

29. Section 63.4340 is amended by revising the section heading and
paragraph (b)(3) to read as follows:

Sec.  63.4340  By what date must I conduct initial performance tests
and other initial compliance demonstrations?

* * * * *
    (b) * * *
    (3) You must complete the compliance demonstration for the initial
compliance period according to the requirements of Sec.  63.4341. The
initial compliance period begins on the applicable compliance date
specified in Sec.  63.4283 and ends on the last day of the 12th full
month after the compliance date. The initial compliance demonstration
includes the results of emission capture system and add-on control
device performance tests conducted according to Sec. Sec.  63.4360,
63.4361, and 63.4362; results of liquid-liquid material balances
conducted according to Sec.  63.4341(e)(5) or (f)(5); calculations
according to Sec.  63.4341 and supporting documentation showing that
during the initial compliance period the organic HAP emission rate was
equal to or less than the applicable emission limit in Table 1 to this
subpart; the operating limits established during the performance tests
and the results of the continuous parameter monitoring required by
Sec.  63.4364; and documentation of whether you developed and
implemented the work practice plan required by Sec.  63.4293.

    The additions and revision read as follows:

Sec.  63.4341  How do I demonstrate initial compliance?

* * * * *
    (e) * * *
    (4) * * * For each controlled web coating/printing 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 emissions reductions using Equation
1 of this section. The equation applies the emission capture system
efficiency and add-on control device efficiency to the mass of organic
HAP contained in the coating, printing, thinning, and cleaning
materials applied in the web coating/printing operation served by the
emission capture system and add-on control device during the compliance
period. For any period of time a deviation specified in Sec.
63.4342(c) or (d) occurs in the controlled web coating/printing
operation, then you must assume zero efficiency for the emission
capture system and add-on control device. Equation 1 of this section
treats the coating, printing, thinning, and

cleaning materials applied during such a deviation as if they were used
on an uncontrolled web coating/printing operation for the time period
of the deviation. * * *
* * * * *
    (5) * * *
    (iii) Determine the mass fraction of volatile organic matter for
each coating, printing, cleaning, and thinning material applied in the
web coating/printing operation controlled by the solvent recovery
system during the compliance period, kg volatile organic matter per kg
coating, printing, cleaning, and thinning material. You may determine
the volatile organic matter mass fraction using Method 24 in appendix
A-7 of part 60, ASTM D2369-10 (R2015), ``Test Method for Volatile
Content of Coatings'' (incorporated by reference, see Sec.  63.14), or
an EPA approved alternative method. Alternatively, you may use
information provided by the manufacturer or supplier of the coating or
printing material. In the event of any inconsistency between
information provided by the manufacturer or supplier and the results of
Method 24, ASTM D2369-10 (R2015), or an approved alternative method,
the test method results will govern.
* * * * *
    (f) * * *
    (4) * * * For each controlled dyeing/finishing 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 emissions reductions using Equation 5 of this
section. The equation applies the emission capture system efficiency
and add-on control device efficiency to the mass of organic HAP
contained in the dyeing and finishing materials applied in the dyeing/
finishing operation served by the emission capture system and add-on
control device during the compliance period. For any period of time a
deviation specified in Sec.  63.4342(c) or (d) occurs in the controlled
dyeing/finishing operation, then you must assume zero efficiency for
the emission capture system and add-on control device. Equation 5 of
this section treats the dyeing and finishing materials applied during
such a deviation as if they were applied on an uncontrolled dyeing/
finishing operation for the time period of the deviation. * * *

31. Section 63.4342 is amended by revising the section heading and
paragraph (c) introductory text, adding paragraph (c)(3), and revising
paragraphs (f) and (h) to read as follows:

Sec.  63.4342  How do I conduct periodic performance tests and
demonstrate continuous compliance with the emission limitations?

* * * * *
    (c) You must demonstrate continuous compliance with each operating
limit required by Sec.  63.4292 that applies to you, as specified in
Table 2 to this subpart, and you must conduct periodic performance
tests as specified in paragraph (c)(3) of this section.
* * * * *
    (3) Except for solvent recovery systems for which you conduct
liquid-liquid material balances according to Sec.  63.4351(d)(5),
within 5 years following the previous performance test, you must
conduct according to the procedures in Sec. Sec.  63.4360, 63.4361, and
63.4362 a periodic performance test of each capture system and add-on
control device used, and you must establish the operating limits
required by Sec.  63.4292. You must conduct the first periodic
performance test and establish the operating limits required by Sec.
63.4292 before March 15, 2022, unless you are already 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 and
have conducted a performance test on or after March 15, 2017.
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.
* * * * *
    (f) As part of each semiannual compliance report required in Sec.
63.4311, you must identify the coating/printing and dyeing/finishing
operation(s) for which you use the emission rate with add-on controls
option. If there were no deviations from the applicable emission
limitations in Sec. Sec.  63.4290, 63.4292, and 63.4293, you must
submit a statement that, as appropriate, the web coating/printing
operations or the dyeing/finishing operations 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 Table 1 to this subpart, and
you achieved the operating limits required by Sec.  63.4292 and the
work practice standards required by Sec.  63.4293 during each
compliance period.
* * * * *
    (h) Before September 12, 2019, 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 web coating/printing or dyeing/finishing 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
determine whether deviations that occur during a period of startup,
shutdown, or malfunction are violations according to the provisions in
Sec.  63.6(e). On and after September 12, 2019, as specified in Sec.
63.4300(b), 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, and determination of whether a source is operating in
compliance with operation and maintenance requirements will be based on
information available to the Administrator.

33. Section 63.4351 is amended by revising paragraphs (a), (d)(4)
introductory text, (d)(5)(iii), and (e) introductory text to read as
follows:

Sec.  63.4351  How do I demonstrate initial compliance?

    (a) You may use the organic HAP overall control efficiency option
or the oxidizer outlet organic HAP concentration option for any
individual web coating/printing operation, for any group of web
coating/printing operations in the affected source, or for all of the
web coating/printing operations in the affected source. You may include
both controlled and uncontrolled web coating/printing operations in a
group for which you use the organic HAP overall control efficiency
option. You must use either the compliant material option, the emission
rate without add-on controls option, or the emission rate with add-on
controls option for any web coating/printing operation(s) in the
affected source for which you do not use either the organic HAP overall
control efficiency option or the oxidizer outlet organic HAP
concentration option. To demonstrate initial compliance, any web
coating/printing operation for which you use the organic HAP overall
control efficiency option must meet the applicable organic HAP overall
control efficiency limitations in Table 1 to this subpart according to
the procedures in paragraph (d) of this section. Any web coating/
printing operation for which you use the oxidizer outlet organic HAP
concentration option must meet the 20 ppmv on a dry basis limit and
achieve 100 percent capture efficiencies according to the procedures in
paragraph (e) of this section. To demonstrate initial compliance with
either option, you also must meet the applicable operating limits in
Sec.  63.4292 according to the procedures in paragraph (b) of this
section and the work practice standards in Sec.  63.4293 according to
the procedures in paragraph (c) of this section. When calculating the
organic HAP overall control efficiency according to this section, do
not include any coating, printing, thinning, or cleaning materials
applied on web coating/printing operations for which you use the
compliant material option, the emission rate without add-on controls
option, the emission rate with add-on controls option, or the oxidizer
outlet organic HAP concentration option. You do not need to redetermine
the mass of organic HAP in coating, printing, thinning, or cleaning
materials that have been reclaimed onsite and reused in web coating/
printing operation(s) for which you use the organic HAP overall control
efficiency option.
* * * * *
    (d) * * *
    (4) Calculate the organic HAP emissions reductions for controlled
web coating/printing operations not using liquid-liquid material
balance. For each controlled web coating/printing 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 emissions reductions using Equation 1 of
Sec.  63.4341. The equation applies the emission capture system
efficiency and add-on control device efficiency to the mass of organic
HAP contained in the coating, printing, thinning, and cleaning
materials applied in the web coating/printing operation served by the
emission capture system and add-on control device during the compliance
period. For any period of time a deviation specified in Sec.
63.4352(c) or (d) occurs in the controlled web coating/printing
operation, then you must assume zero efficiency for the emission
capture system and add-on control device. Equation 1 of Sec.  63.4341
treats the coating, printing, thinning, and cleaning materials applied
during such a deviation as if they were applied on an uncontrolled web
coating/printing operation for the time period of the deviation.
* * * * *
    (5) * * *
    (iii) Determine the mass fraction of volatile organic matter for
each coating and printing material applied in the web coating/printing
operation controlled by the solvent recovery system during the
compliance period, kg volatile organic matter per kg coating and
printing material. You may determine the volatile organic matter mass
fraction using Method 24 in appendix A-7 of part 60, ASTM D2369-10
(R2015), ``Test Method for Volatile Content of Coatings'' (incorporated
by reference, see Sec.  63.14), or an EPA approved alternative method.
Alternatively, you may use information provided by the manufacturer or
supplier of the coating or printing material. In the event of any
inconsistency between information provided by the manufacturer or
supplier and the results of Method 24, ASTM D2369-10 (R2015), or an
approved alternative method, the test method results will govern.
* * * * *
    (e) Compliance with oxidizer outlet organic HAP concentration
limit. You must follow the procedures in paragraphs (e)(1) through (3)
of this section to demonstrate compliance with the oxidizer outlet
organic HAP concentration limit of no greater than 20 ppmv on a dry
basis.
* * * * *

0
34. Section 63.4352 is amended by revising paragraph (h) to read as
follows:

Sec.  63.4352  How do I demonstrate continuous compliance with the
emission limitations?

* * * * *
    (h) Before September 12, 2019, 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 web coating/printing 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 determine whether deviations that occur during a period of
startup, shutdown, or malfunction are violations according to the
provisions in Sec.  63.6(e). On and after September 12, 2019, as
specified in Sec.  63.4300(b), 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, and determination of whether a source is
operating in compliance with operation and maintenance requirements
will be based on information available to the Administrator.

35. Section 63.4360 is amended by revising paragraphs (a) introductory
text and (a)(1) to read as follows:

Sec.  63.4360  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec.
63.4340 or Sec.  63.4350 according to the requirements in this section,
unless you obtain a waiver of the performance test according to the
provisions in Sec.  63.7(h).
    (1) Representative web coating/printing or dyeing/finishing
operation operating conditions. You must conduct the performance test
under representative operating conditions for the web coating/printing
or dyeing/finishing operation. Operations during periods of startup,
shutdown, or nonoperation do not constitute representative conditions
for purposes of conducting a performance test. The owner or operator
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 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.

36. Section 63.4362 is amended by revising paragraphs (a)(1) through
(4) and (b) introductory text to read as follows:

Sec.  63.4362  How do I determine the add-on control device emission
destruction or removal efficiency?

* * * * *
    (a) * * *
    (1) Use Method 1 or 1A in appendix A-1 of part 60, as appropriate,
to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, or 2F in appendix A-1, or Method 2G
in appendix A-2, of part 60, as appropriate, to measure gas volumetric
flow rate.
    (3) Use Method 3, 3A, or 3B in appendix A of part 60, as
appropriate, for gas analysis to determine dry molecular weight. You
may also use as an alternative to Method 3B, the manual method for
measuring the oxygen, carbon dioxide, and carbon monoxide content of
exhaust gas in ANSI/ASME, PTC 19.10-1981, ``Flue and Exhaust Gas
Analyses [Part 10, Instruments and Apparatus]'' (incorporated by
reference, see Sec.  63.14).
    (4) Use Method 4 in appendix A of part 60 to determine stack gas
moisture.
* * * * *
    (b) Measure the volatile organic matter concentration as carbon at
the inlet and outlet of the add-on control device simultaneously, using
Method 25 or 25A in appendix A-7 of part 60. If you are demonstrating
compliance with the oxidizer outlet organic HAP concentration limit,
only the outlet volatile organic matter concentration must be
determined. The outlet volatile organic matter concentration is
determined as the average of the three test runs. You may use Method 18
in appendix A-6 of part 60 to subtract methane emissions from measured
volatile organic matter concentration as carbon.

0
a. Revising paragraphs (a)(6) through (8) and (c) introductory text;
0
b. Redesignating paragraphs (c)(i) through (iii) as (c)(1) through (3),
respectively; and
0
c. Revising newly redesignated paragraph (c)(1).
    The revisions read as follows:

Sec.  63.4364  What are the requirements for CPMS installation,
operation, and maintenance?

    (a) * * *
    (6) At all times, you must maintain the monitoring system in
accordance with Sec.  63.4300(b) and in proper working order including,
but not limited to, keeping readily available necessary parts for
routine repairs of the monitoring equipment.
    (7) Before September 12, 2019, except for monitoring malfunctions,
associated repairs, or required quality assurance or control activities
(including calibration checks or required zero and span adjustments),
you must conduct all monitoring at all times that the unit is
operating. On and after September 12, 2019, you must operate the CPMS
and collect emission capture system and add-on control device parameter
data at all times in accordance with Sec.  63.4300(b). Data recorded
during monitoring malfunctions, associated repairs, out-of-control
periods, or required quality assurance or control activities shall not
be used for purposes of calculating the emissions concentrations and
percent reductions specified in Table 1 to this subpart. You must use
all the data collected during all other periods in assessing compliance
of the control device and associated control system. A monitoring
malfunction is any sudden, infrequent, not reasonably preventable
failure of the monitoring system to provide valid data. Monitoring
failures that are caused in part by poor maintenance or careless
operation are not malfunctions.
    (8) Except for periods of required quality assurance or control
activities, any averaging period during which the CPMS fails to operate
and record data continuously as required by paragraph (a)(1) of this
section, or during which generated data cannot be included in
calculating averages as specified in paragraph (a)(7) of this section,
constitutes a deviation, and you must notify the Administrator in
accordance with Sec.  63.4311(a).
* * * * *
    (c) Oxidizers. If you are using an oxidizer to comply with the
emission standards, you must comply with paragraphs (c)(1) through (3)
of this section.
    (1) Install, calibrate, maintain, and operate temperature
monitoring equipment according to the manufacturer's specifications.
The calibration of the chart recorder, data logger, or temperature
indicator must be verified every 3 months or the chart recorder, data
logger, or temperature indicator must be replaced. A thermocouple is
considered part of the temperature indicator for purposes of performing
periodic calibration and verification checks.

41. Section 63.4900 is revised to read as follows:

Sec.  63.4900  What are my general requirements for complying with this
subpart?

    (a) The affected source must be in compliance at all times with the
applicable emission limitations specified in Sec. Sec.  63.4890,
63.4892, and 63.4893.
    (b) Before September 12, 2019, 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 September 12, 2019, 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 September 12, 2019, if your affected source uses an
emission capture system and add-on control device to comply with the
emission limitations in Sec.  63.4890, you must develop a written
startup, shutdown, and malfunction plan (SSMP) according to the
provisions in Sec.  63.6(e)(3). The SSMP must address the startup,
shutdown, and corrective actions in the event of a malfunction of the
emission capture system or the add-on control device. The SSMP 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. A startup, shutdown, and malfunction plan is not required
on and after September 12, 2019.

medium to the EPA. The electronic medium shall be clearly marked as CBI
and mailed to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group Leader,
Measurement Policy Group, MD C404-02, 4930 Old Page Rd., Durham, NC
27703. The same file with the CBI omitted shall be submitted to the EPA
via the EPA's CDX as described earlier in this paragraph.
    (d) If you are required to electronically submit a report through
CEDRI in the EPA's CDX, and due to a planned or actual outage of either
the EPA's CEDRI or CDX systems within the period of time beginning 5
business days prior to the date that the submission is due, you will be
or are precluded from accessing CEDRI or CDX and submitting a required
report within

the time prescribed, you may assert a claim of EPA system outage for
failure to timely comply with the reporting requirement. 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. You
must provide to the Administrator a written description identifying the
date, time and length of the outage; a rationale for attributing the
delay in reporting beyond the regulatory deadline to the EPA system
outage; describe the measures taken or to be taken to minimize the
delay in reporting; and identify a 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. In any circumstance, the report
must be submitted electronically as soon as possible after the outage
is resolved. 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.
    (e) If you are required to electronically submit a report through
CEDRI in the EPA's CDX and 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 5 business days prior to the
date the submission is due, the owner or operator may assert a claim of
force majeure for failure to timely comply with the reporting
requirement. 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). If you intend to
assert a claim of force majeure, 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. You must provide to the
Administrator a written description of the force majeure event and a
rationale for attributing the delay in reporting beyond the regulatory
deadline to the force majeure event; describe the measures taken or to
be taken to minimize the delay in reporting; and identify a 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. In
any circumstance, the reporting must occur as soon as possible after
the force majeure event occurs. 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.

45. Section 63.4930 is amended by revising paragraphs (j), (k)
introductory text, and (k)(1) and (2) to read as follows:

Sec.  63.4930  What records must I keep?

* * * * *
    (j) Before September 12, 2019, you must keep records of the date,
time, and duration of each deviation. On and after September 12, 2019,
for each deviation from an emission limitation reported under Sec.
63.4920(a)(5) through (7), you must keep a record of the information
specified in paragraphs (j)(1) through (4) of this section, as
applicable.
    (1) The date, time, and duration of the deviation, as reported
under Sec.  63.4920(a)(5) through (7).
    (2) A list of the affected sources or equipment for which the
deviation occurred and the cause of the deviation, as reported under
Sec.  63.4920(a)(5) through (7).
    (3) An estimate of the quantity of each regulated pollutant emitted
over any applicable emission limit in Sec.  63.4890 or any applicable
operating limit(s) in Table 1 to this subpart, and a description of the
method used to calculate the estimate, as reported under Sec.
63.4920(a)(5) through (7).
    (4) A record of actions taken to minimize emissions in accordance
with Sec.  63.4900(b) and any corrective actions taken to return the
affected unit to its normal or usual manner of operation.
    (k) If you use the emission rate with add-on controls option, you
must also keep the records specified in paragraphs (k)(1) through (8)
of this section.
    (1) Before September 12, 2019, for each deviation, a record of
whether the deviation occurred during a period of startup, shutdown, or
malfunction. The record in this paragraph (k)(1) is not required on and
after September 12, 2019.
    (2) Before September 12, 2019, the records in Sec.  63.6(e)(3)(iii)
through (v) related to startup, shutdown, and malfunction. The records
in this paragraph (k)(2) are not required on and after September 12,
2019.

46. Section 63.4931 is amended by revising paragraph (a) to read as
follows:

Sec.  63.4931  In what form and for how long must I keep my records?

    (a) Your records must be in a form suitable and readily available
for expeditious review, according to Sec.  63.10(b)(1). Where
appropriate, the records may be maintained as electronic spreadsheets
or as a database. Any records required to be maintained by this subpart
that are in reports that were 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.

47. Section 63.4941 is amended by revising paragraphs (a)(1)(i), (a)(2)
and (4), and (b)(1), the definitions of ``Mvolatiles'' and
``Davg'' in Equation 1 in paragraph (b)(3), and paragraphs
(c) and (e) to read as follows:

Sec.  63.4941  How do I demonstrate initial compliance with the
emission limitations?

* * * * *
    (a) * * *
    (1) * * *
    (i) Count each organic HAP in Table 5 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 organic HAP compounds. For example,
if toluene (not listed in Table 5 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 (for example, 0.3791).
* * * * *
    (2) Method 24 in appendix A-7 of 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 (R2015),
``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 5 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 organic HAP
compounds. For example, if toluene (not listed in Table 5 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.
* * * * *
    (b) * * *
    (1) Test results. You may use ASTM D2697-03 (R2014), ``Standard
Test Method for Volume Nonvolatile Matter in Clear or Pigmented
Coatings'', or D6093-97 (R2016), ``Standard Test Method for Percent
Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium
Gas Pycnometer'' (both 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. Alternatively, you may
use another test method once you obtain approval from the Administrator
according to the requirements of Sec.  63.7(f).
* * * * *
    (3) * * *

Mvolatiles = Total volatile matter content of the
coating, including HAP, volatile organic compounds (VOC), water, and
exempt compounds, determined according to Method 24 in appendix A-7
of part 60, or according to ASTM D2369--10 (R2015) Standard Test
Method for Volatile Content of Coatings (incorporated by reference,
see Sec.  63.14), grams volatile matter per liter coating.
Davg = Average density of volatile matter in the coating,
grams volatile matter per liter volatile matter, determined from
test results using ASTM D1475-13, ``Standard Test Method for Density
of Liquid Coatings, Inks, and Related Products'' (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 test results and other
information sources, the test results will take precedence.

    (c) Determine the density of each coating. You must determine the
density of each coating used during the compliance period from test
results using ASTM 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
D1475-13 test results and the supplier's or manufacturer's information,
the test results will take precedence.
* * * * *
    (e) Compliance demonstration. The calculated organic HAP content
for each coating used during the initial compliance period must be less
than or equal to the applicable emission limit in Sec.  63.4890 and
each thinner and cleaning material used during the initial compliance
period must contain no organic HAP, determined according to paragraph
(a) of this section. You must keep all records required by Sec. Sec.
63.4930 and 63.4931. As part of the Notification of Compliance Status
required in Sec.  63.4910(c) and the semiannual compliance reports
required in Sec.  63.4920, you must identify each coating operation and
group of coating operations for which you used the compliant material
option. If there were no deviations from the emission limit, include a
statement that each coating operation was in compliance with the
emission limitations during the initial compliance period because it
used no coatings for which the organic HAP content exceeded the
applicable emission limit in Sec.  63.4890, and it used no thinners or
cleaning materials that contained organic HAP.

    (h) Calculate the organic HAP emission reduction for controlled
coating operations not using liquid-liquid material balance. 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,
thinners, and cleaning materials that are used in the coating operation
served by the emission capture system and add-on control device during
the compliance period. For any period of time a deviation specified in
Sec.  63.4962(c) or (d) occurs in the controlled coating operation, you
must assume zero efficiency for the emission capture system and add-on
control device. 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:
[GRAPHIC] [TIFF OMITTED] TR15MR19.001

Where:

HR = Mass of organic HAP emission reduction for the
controlled coating operation during the compliance period, kg.
AI = Total mass of organic HAP in the coatings used in
the controlled coating operation during the compliance period,
excluding coatings used during deviations, kg, as calculated in
Equation 1A of this section.
BI = Total mass of organic HAP in the thinners used in
the controlled coating operation during the compliance period,
excluding thinners used during deviations, kg, as calculated in
Equation 1B of this section.
CI = Total mass of organic HAP in the cleaning materials
used in the controlled coating operation during the compliance
period, excluding cleaning materials used during deviations, kg, as
calculated in Equation 1C of this section.
Rw = Total mass of organic HAP in waste materials sent or
designated for shipment to a hazardous waste TSDF for treatment

or disposal during the compliance period, kg, determined according
to Sec.  63.4951(e)(4). The mass of any waste material reused during
the same compliance period may not be included in Rw.
(You may assign a value of zero to Rw if you do not wish
to use this allowance.)
CE = Capture efficiency of the emission capture system vented to the
add-on control device, percent. Use the test methods and procedures
specified in Sec. Sec.  63.4963 and 63.4964 to measure and record
capture efficiency.
DRE = Organic HAP destruction or removal efficiency of the add-on
control device, percent. Use the test methods and procedures in
Sec. Sec.  63.4963 and 63.4965 to measure and record the organic HAP
destruction or removal efficiency.
Hunc = Total mass of organic HAP in the coatings,
thinners, and cleaning materials used during all deviations
specified in Sec.  63.4962(c) and (d) that occurred during the
compliance period in the controlled coating operation, kg, as
calculated in Equation 1D of this section.

* * * * *
    (j) * * *
    (3) Determine the mass fraction of volatile organic matter for each
coating, thinner, and cleaning material used in the coating operation
controlled by the solvent recovery system during the compliance period.
You may determine the volatile organic matter mass fraction using
Method 24 in appendix A-7 of part 60, ASTM D2369-10 (R2015), ``Test
Method for Volatile Content of Coatings'' (incorporated by reference,
see Sec.  63.14), or an EPA-approved alternative method. Alternatively,
you may use 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, ASTM
D2369-10 (R2015), or an approved alternative method, the test method
results will govern.

51. Section 63.4962 is amended by revising the section heading and
paragraph (c) introductory text and adding paragraph (c)(3) to read as
follows:

Sec.  63.4962  How do I conduct periodic performance tests and
demonstrate continuous compliance with the emission limitations?

* * * * *
    (c) You must demonstrate continuous compliance with each operating
limit required by Sec.  63.4892 that applies to you, as specified in
Table 1 to this subpart, and you must conduct periodic performance
tests as specified in paragraph (c)(3) of this section.
* * * * *
    (3) Except for solvent recovery systems for which you conduct
liquid-liquid material balances according to Sec.  63.4961(j), within 5
years following the previous performance test, you must conduct
according to the procedures in Sec. Sec.  63.4963, 63.4964, and 63.4965
a periodic performance test of each capture system and add-on control
device used, and you must establish the operating limits required by
Sec.  63.4892. You must conduct the first periodic performance test and
establish the operating limits required by Sec.  63.4892 before March
15, 2022, unless you are already 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 and have
conducted a performance test on or after March 15, 2017. 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.

52. Section 63.4963 is amended by revising paragraphs (a) introductory
text and (a)(1) to read as follows:

Sec.  63.4963  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. Sec.
63.4960 and 63.4962 according to the requirements in this section
unless you obtain a waiver of the performance test according to the
provisions in Sec.  63.7(h).
    (1) Representative coating operation operating conditions. You must
conduct the performance test under representative operating conditions
for the coating operation. Operations during periods of startup,
shutdown, or nonoperation do not constitute representative conditions
for purposes of conducting a performance test. The owner or operator
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 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.
