    The results of the Printing, Coating, and Dyeing of Fabrics and
Other Textiles source category demographic analysis indicate that
emissions from the source category expose approximately 8,500 people to
a cancer risk at or above 1-in-1 million and no one to a chronic
noncancer HI greater than 1. The percentages of the at-risk population
in the following specific demographic groups are higher than their
respective nationwide percentages: ``African American,'' ``Over 25
Without a High School Diploma,'' and ``Below the Poverty Level.''
    The methodology and the results of the demographic analysis are
presented in a technical report, Risk and Technology Review--Analysis
of Demographic Factors for Populations Living Near Printing, Coating,

    The results of the Surface Coating of Metal Furniture source
category demographic analysis indicate that emissions from the source
category expose approximately 2,100 people to a cancer risk at or above
1-in-1 million and no one to a chronic noncancer HI greater than 1. The
percentages of the at-risk population in the following specific
demographic groups are higher than their respective nationwide
percentages: ``Hispanic or Latino,'' ``Over 25 Without a High School
Diploma,'' and ``Below the Poverty Level.''

Metal Furniture Source Category Operations, available in the Surface
Coating of Metal Furniture Docket.

G. What analysis of children's environmental health did we conduct?

    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 summarized in
section IV.A of this preamble and are further documented in the Large
Appliances Risk Assessment Report, Fabrics and Other Textiles Risk
Assessment Report, and Metal Furniture Risk Assessment Report in the
Surface Coating of Large Appliances Docket, Printing, Coating, and
Dyeing of Fabrics and Other Textiles Docket, and Surface Coating of
Metal Furniture Docket, respectively.

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Orders 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was,
therefore, not submitted to the Office of Management and Budget (OMB)
for review.

B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs

    This action is not an Executive Order 13771 regulatory action
because this action is not significant under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    The information collection activities in each of these three
subparts have been submitted for approval to OMB under the PRA.
1. Surface Coating of Large Appliances
    The Information Collection Request (ICR) document that the EPA
prepared has been assigned EPA ICR number 1954.08. You can find a copy
of the ICR in the Surface Coating of Large Appliances Docket (Docket ID
No. EPA-HQ-OAR-2017-0670), and it is briefly summarized here.
    As part of the RTR for the Surface Coating of Large Appliances
NESHAP, the EPA is not revising the emission limitation requirements
for this subpart. The EPA has revised the SSM provisions of the rule
and is requiring the use of electronic data reporting for future
performance test data submittals and semi-annual reporting. This
information would be collected to assure compliance with 40 CFR part
63, subpart NNNN. The EPA is finalizing a requirement to conduct
control device performance testing no less frequently than once every 5
years for facilities using the emission rate with add-on controls
compliance option, but this is not estimated to affect any facilities
in this source category.
    Respondents/affected entities: Facilities performing surface
coating of large appliances.
    Respondent's obligation to respond: Mandatory (40 CFR part 63,
subpart NNNN).
    Estimated number of respondents: In the 3 years after the
amendments are final, approximately 10 respondents per year would 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
30. Years 2 and 3 would have no responses.
    Total estimated burden: The average annual burden to the large
appliance facilities over the 3 years after the amendments are final is
estimated to be 77 hours (per year). The average annual burden to the
Agency over the 3 years after the amendments are final is estimated to
be 15 hours (per year) for the Agency. Burden is defined at 5 CFR
1320.3(b).
    Total estimated cost: The average annual cost to the large
appliance facilities is $7,700 in labor costs, in the first 3 years
after the amendments are final. The total average annual Agency cost
over the first 3 years after the amendments are final is estimated to
be $700.
2. Printing, Coating, and Dyeing of Fabrics and Other Textiles
    The ICR document that the EPA prepared has been assigned EPA ICR
number 2071.08. You can find a copy of the ICR in the Printing,
Coating, and Dyeing of Fabrics and Other Textiles Docket (Docket ID No.
EPA-HQ-OAR-2017-0668), and it is briefly summarized here.
    As part of the RTR for the Printing, Coating, and Dyeing of Fabrics
and Other Textiles NESHAP, the EPA is not revising the emission
limitation requirements for this subpart. The EPA has revised the SSM
provisions of the rule and is requiring the use of electronic data
reporting for future performance test data submittals and semiannual
reports. This information is being collected to assure compliance with
40 CFR part 63, subpart OOOO. The EPA is finalizing a requirement to
conduct control device performance testing no less frequently than once
every 5 years for facilities using the emission rate with add-on
controls compliance option.
    Respondents/affected entities: Facilities performing printing,
coating, and dyeing of fabrics and other textiles.
    Respondent's obligation to respond: Mandatory (40 CFR part 63,
subpart OOOO).
    Estimated number of respondents: In the 3 years after the
amendments are final, approximately 43 respondents per year will be
subject to the NESHAP and no additional respondents are expected to
become subject to the NESHAP during that period. The EPA estimates that
13 facilities will be required to conduct performance testing for 19
control devices in the 3 three years after the amendments are final.
    Frequency of response: The total number of responses in year 1 is
129. Year 2 will have no responses. Year 3 will have 19 responses
related to control device performance tests.
    Total estimated burden: The average annual burden to the Printing,
Coating, and Dyeing of Fabrics and Other Textiles coating facilities
over the 3 years after amendments are finalized is estimated to be 548
hours (per year). The average annual burden to the Agency over the 3
years after the amendments are final is estimated to be 133 hours (per
year) for the Agency. Burden is defined at 5 CFR 1320.3(b).
    Total estimated cost: The average annual cost to the Printing,
Coating, and Dyeing of Fabrics and Other Textiles coating facilities is
$50,000 in labor costs and $120,000 in capital and operation and
maintenance costs in the first 3 years after the amendments are final.
The average annual Agency cost over the first 3 years after the
amendments are final is estimated to be $14,000.
3. Surface Coating of Metal Furniture
    The ICR document that the EPA prepared has been assigned EPA ICR
number 1952.08. You can find a copy of the ICR in the Surface Coating
of Metal Furniture Docket (Docket ID No. EPA-HQ-OAR-2017-0669), and it
is briefly summarized here.
    As part of the RTR for the Surface Coating of Metal Furniture
NESHAP, the EPA is not revising the emission limitations for this
subpart. The EPA has revised the SSM provisions of the rule and is
requiring the use of electronic data reporting for future performance
test data submittals and semi-annual reporting. This information would
be collected to assure compliance with 40 CFR part 63, subpart RRRR.
The EPA is finalizing a requirement to conduct control device
performance testing no less frequently than once every 5 years for
facilities using the emission rate with add-on controls compliance
option, but this is not estimated to affect any facilities in this
source category.
    Respondents/affected entities: Facilities performing surface
coating of metal furniture.
    Respondent's obligation to respond: Mandatory (40 CFR part 63,
subpart RRRR).
    Estimated number of respondents: In the 3 years after the
amendments are final, approximately 16 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
48. Years 2 and 3 would have no responses.
    Total estimated burden: The average annual burden to the large
appliance facilities over the 3 years after the amendments are
finalized is estimated to be 123 hours (per year). The average annual
burden to the Agency over the 3 years after the amendments are final is
estimated to be 25 hours (per year) for the Agency. Burden is defined
at 5 CFR 1320.3(b).
    Total estimated cost: The average annual cost to the metal
furniture facilities is $11,000 in labor costs in the first 3 years
after the amendments are final. The total average annual Agency cost
over the first 3 years after the amendments are final is estimated to
be $1,200.
    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.

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. This
action will not impose any requirements on small entities. No
facilities meeting the Small Business Administration's definition of a
small business will face significant control costs, based on the
economic impact analysis completed for this action. More information
and details of this analysis is provided in the technical documents
titled Economic Impact and Small Business Screening Assessments for the
National Emission Standards for Hazardous Air Pollutants for the
Surface Coating of Large Appliances (Subpart NNNN), Economic Impact and
Small Business Screening Assessments for the National Emission
Standards for Hazardous Air Pollutants for the Printing, Coating, and
Dyeing of Fabrics and Other Textiles (Subpart OOOO), and Economic
Impact and Small Business Screening Assessments for the National
Emission Standards for Hazardous Air Pollutants for the Surface Coating
of Metal Furniture (Subpart RRRR), available in the Surface Coating of
Large Appliances Docket, Printing, Coating, and Dyeing of Fabrics and
Other Textiles Docket, and Surface Coating of Metal Furniture Docket,
respectively.

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 (large
appliances surface coating; printing, coating, and dyeing of fabrics
and other textiles; surface coating of metal furniture). 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 IV.A of this preamble.

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 action involves technical standards. The EPA amended the three
NESHAP in this action to provide owners and operators with the option
of conducting 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.
    For the Surface Coating of Metal Furniture NESHAP, the Printing,
Coating, and Dyeing of Fabrics and Other Textiles NESHAP, and the
Surface Coating of Large Appliances NESHAP, the EPA incorporates by
reference ASTM D2369-10 (2015)\e\, ``Test Method for Volatile Content
of Coatings,'' which describes a procedure for the determination of the
weight percent volatile content of solvent-borne and water-borne
coatings, as an acceptable alternative to EPA Method 24,
``Determination of Volatile Matter Content, Water Content, Density,
Volume Solids, and Weight Solids of Surface Coatings.''
    For the Surface Coating of Large Appliances NESHAP, the EPA
incorporates by reference ASTM D2111-10 (2015), ``Standard Test Methods
for Specific Gravity of Halogenated Organic Solvents and Their
Admixtures,'' These test methods cover the determination of the
specific gravity of halogenated organic solvents and solvent
admixtures. In addition. the EPA incorporates by reference ASTM D1475-
13, ``Standard Test Method for Density of Liquid Coatings, Inks, and
Related Products,'' which is already specified in 40 CFR part 63,
subpart NNNN, and covers the measurement of density of paints, inks,
varnishes, lacquers, and components thereof, other than pigments, when
in fluid form.
    We found three voluntary consensus standards already allowed in the
Surface Coating of Large Appliances NESHAP and the Surface Coating of
Metal Furniture NESHAP that have been replaced with newer versions of
the methods. ASTM Dl475-13, ``Standard Test Method for Density of
Liquid Coatings, Inks, and Related Products,'' has replaced ASTM D1475-
90; ASTM D2697-03 (2014),''Standard Test Method for Volume Nonvolatile
Matter in Clear or Pigmented Coatings,'' believed to be applicable to
the determination of the volume of nonvolatile matter of a variety of
coatings, has replaced ASTM D2697-86 (1998); and ASTM D6093-97 (2016),
``Standard Test Method for Percent Volume Nonvolatile Matter in Clear
or Pigmented Coatings Using Helium Gas Pycnometer,'' which covers the
determination of the percent volume nonvolatile matter of a variety of
clear and pigmented coatings, has replaced ASTM D6093-97 (2003).
    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 https://www.astm.org/.
    The EPA decided not to include certain other voluntary consensus
standards; 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 Large Appliances,
March 2018, Voluntary Consensus Standard Results for Printing, Coating,
and Dyeing of Fabrics and Other Textiles, March 2018, and Voluntary
Consensus Standard Results for Surface Coating of Metal Furniture,
March 2018, in the Surface Coating of Large Appliances Docket (Docket
ID No. EPA-HQ-OAR-2017-0670), Printing, Coating, and Dyeing of Fabrics
and Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668), and
Surface Coating of Metal Furniture Docket (Docket ID No. EPA-HQ-OAR-
2017-0669), respectively, for the reasons for these determinations.
    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 these final actions do 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). This action increases the level of environmental
protection for all affected populations. The results of this evaluation
are contained in section IV.A of this preamble and the technical
reports, Risk and Technology Review--Analysis of Demographic Factors
for Populations Living Near Printing, Coating, and Dyeing of Fabrics
and Other Textiles Source Category Operations, September 2017; Risk and
Technology Review--Analysis of Demographic Factors for Populations
Living Near Surface Coating of Metal Furniture Source Category
Operations, October 2017; and Risk and Technology Review--Analysis of
Demographic Factors for Populations Living Near Surface Coating of
Large Appliances Source Category Operations Demographic Analysis,
September 2017, which are available in the dockets for this action.

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).

3. Section 63.4100 is amended by revising paragraphs (b) and (d) to
read as follows:

Sec.  63.4100  What are my general requirements for complying with this
subpart?

* * * * *
    (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.
* * * * *
    (d) Before September 12, 2019, if your affected source uses an
emission capture system and add-on control device, you must develop a
written startup, shutdown, and malfunction plan according to the
provisions in Sec.  63.6(e)(3). The plan 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 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. A startup, shutdown, and malfunction plan is not required
on and after September 12, 2019.

    (b) 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.
63.4110(a)(2) and (b) to the EPA via CEDRI. The CEDRI 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 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.
    (c) 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 Sec.  63.4120 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 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.
    (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.

8. Section 63.4131 is amended by revising paragraph (a) to read as
follows:

Sec.  63.4131  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 data base. 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.

9. Section 63.4141 is amended by revising paragraphs (a)(1)(i) and
(ii), (a)(2) and (4), and (b)(1), the definitions of
``mvolatiles'' and ``Davg'' in Equation 1 of
paragraph (b)(3), and paragraph (c) to read as follows:

Sec.  63.4141  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).
    (ii) Calculate the total mass fraction of organic HAP in the test
material by adding up the individual organic HAP mass fractions and
truncating the result to three places after the decimal point (for
example, 0.763).
    (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 they represent 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) ASTM D2697-03 (R2014) or D6093-97 (R2016). 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'' (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.
* * * * *
    (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,'' ASTM D2111-10
(R2015), ``Standard Test Methods for Specific Gravity of Halogenated
Organic Solvents and Their Admixtures'' (both incorporated by
reference, see Sec.  63.14); if you use this method, the specific
gravity must be corrected to a standard temperature, 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 (R2015) test results and other information sources, the
test results will take precedence.

    (c) Determine the density of each coating. 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, ASTM D2111-10

(R2015), ``Standard Test Methods for Specific Gravity of Halogenated
Organic Solvents and Their Admixtures''(both incorporated by reference,
see Sec.  63.14); if you use this method, the specific gravity must be
corrected to a standard temperature, 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 test results from ASTM D1475-13 or ASTM D2111-10 (R2015) and
the supplier's or manufacturer's information, the test results will
take precedence.

14. Section 63.4161 is amended by revising paragraphs (g) introductory
text and (h)(3) to read as follows:

Sec.  63.4161  How do I demonstrate initial compliance?

* * * * *
    (g) Calculate the organic HAP emissions 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 organic HAP
emissions reduction, using Equation 1 of this section, by applying 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.
63.4163(c) or (d) occurs in the controlled coating operation, you must
assume zero efficiency for the emission capture system and add-on
control device. For the purposes of completing the compliance
calculations, you must treat the materials used during a deviation on a
controlled coating operation as if they were used on an uncontrolled
coating operation for the time period of the deviation. You must not
include those materials in the calculations of organic HAP emissions
reduction in Equation 1 of this section.

Where:
HC = mass of organic HAP emissions 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, kg, as calculated in Equation 1A
of this section.
BI = total mass of organic HAP in the thinners used in
the controlled coating operation, 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, kg, as calculated in Equation 1C of this section.
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.  63.4164 and 63.4165 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.  63.4164 and 63.4166 to measure and record the organic HAP
destruction or removal efficiency.

    (h) * * *
    (3) Determine the mass fraction of volatile organic matter for each
coating used in the coating operation controlled by the solvent
recovery system during the compliance period, kg volatile organic
matter per kg coating. 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.

23. Section 63.4300 is amended by revising paragraphs (a)(3)(i), (b),
and (c) to read as follows:

Sec.  63.4300  What are my general requirements for complying with this
subpart?

    (a) * * *
    (3) * * *
    (i) Before September 12, 2019, the web coating/printing or dyeing/
finishing operation(s) must be in compliance with the applicable
emission limit in Table 1 to this subpart or minimize emissions at all
times as required by Sec.  63.6(e)(1). On and after September 12, 2019,
the web coating/printing or dyeing/finishing operation(s) must be in
compliance with the applicable emission limit in Table 1 to this
subpart at all times.
* * * * *
    (b) Before September 12, 2019, you must always operate and maintain
your affected source, including air pollution control and monitoring
equipment, 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, you must develop a
written startup, shutdown, and malfunction plan according to the
provisions in Sec.  63.6(e)(3). The plan 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 plan must
also address any web coating/printing or dyeing/finishing operation
equipment such as conveyors that move the substrate among enclosures
that may cause increased emissions or that would affect capture
efficiency if the process equipment malfunctions. A startup, shutdown,
and malfunction plan is not required on and after September 12, 2019.
