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 this proposed rule have
been submitted for approval to OMB under the PRA. The Information
Collection Request (ICR) document that the EPA prepared has been
assigned EPA ICR number 1951.09, OMB Control No. 2060-0511. You can
find a copy of the ICR in the docket for this rule, and it is briefly
summarized here. The information collection requirements are not
enforceable until OMB approves them.
    The POWC NESHAP applies to existing facilities and new POWC
facilities. In general, all NESHAP standards require initial
notifications, notifications of compliance status, performance tests,
performance evaluation reports, and periodic reports by the owners/
operators of the affected facilities. They are also required to
maintain records of the occurrence and duration of any malfunction in
the operation of an affected facility, or any period during which the
monitoring system is inoperative. These notifications, reports, and
records are essential in determining compliance, and are required of
all affected facilities subject to NESHAP. This information is being
collected to assure compliance with 40 CFR part 63, subpart JJJJ.
    Respondents/affected entities: POWC facilities.
    Respondent's obligation to respond: Mandatory (40 CFR Part 63,
Subpart JJJJ).
    Estimated number of respondents: 170.
    Frequency of response: Initially, occasionally, and semiannually.
    Total estimated burden: 17,300 hours (per year). Burden is defined
at 5 CFR 1320.3(b).
    Total estimated cost: $2,735,000 (per year), includes $765,000
annualized capital and operation and maintenance costs.
    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
this ICR, 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
activities contained in this 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
small entities subject to the requirements of this action and the
annualized costs associated with the final requirements in this action
for the affected small entities are described in section V.D above.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate of $100 million
or more as described in UMRA, 2 U.S.C. 1531-1538. 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. It will not have substantial direct effects on
tribal governments, on the relationship between the federal government
and Indian tribes, or on the distribution of power and responsibilities
between the federal government and Indian tribes. No tribal governments
own facilities subject to the NESHAP. 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 risks 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 and IV of this preamble and further documented in the risk
report titled Residual Risk Assessment for the Paper and Other Web
Source Category in Support of the 2020 Risk and Technology Review Final
Rule, which can be found in the docket for this action (Docket ID No.
EPA-HQ-OAR-2018-0416).

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 is finalizing the
following six VCS as alternatives to EPA Method 24 and is incorporating
them by reference for the first time in the finalized amendments:
     ASTM D2369-10 (Reapproved 2015)\e\, ``Standard Test Method
for Volatile Content of Coatings.'' This test method describes a
procedure used for the determination of the weight percent volatile
content of solvent-borne and waterborne coatings.
     ASTM D2697-03 (Reapproved 2014), ``Standard Test Method
for Volume Nonvolatile Matter in Clear or Pigmented Coatings.'' This
test method is applicable to the determination of the volume of
nonvolatile matter in coatings.
     ASTM D3960-98, ``Standard Practice for Determining
Volatile Organic Compound (VOC) Content of Paints and Related
Coatings.'' This test method is used for the measurement of the VOC
content of solvent borne and waterborne paints and related coatings.
This method is an acceptable alternative to EPA Method 24 because the
regulation allows for the use of VOC content as a surrogate for HAP.
     ASTM D6093-97 (Reapproved 2016), ``Standard Test Method
for Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings
Using a Helium Gas Pycnometer.'' This test method is used for the
determination of the percent volume nonvolatile matter in clear and
pigmented coatings.
     ASTM D2111-10 (Reapproved 2015), ``Standard Test Methods
for Specific Gravity of Halogenated Organic Solvents and Their
Admixtures.'' This test method is used for the determination of the
specific gravity of halogenated organic solvents and solvent
admixtures.
     ASTM D1963-85 (Reapproved 1996), ``Standard Test Method
for Specific Gravity of Drying Oils, Varnishes, Resins, and Related
Materials at 25[deg] C.'' This test method is used for the
determination of the specific gravity of drying oils, varnishes, alkyd
resins, fatty acids, and related materials. This method is an
acceptable alternative to EPA Method 24 for density only and may not be
valid for all coatings and is valid at the designated temperature (25
degrees Celsius). This standard was withdrawn in 2004 with no
replacement; there is no later version.
    These standards are reasonably 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/.
    While the EPA has identified another 19 VCS as being potentially
applicable to this NESHAP, we have decided not to use these VCS in this
rulemaking. The use of these VCS would not be practical due to lack of
equivalency, documentation, validation date, and other important
technical and policy considerations. See the memorandum titled
Voluntary Consensus Standard Results for National Emission Standards
for Hazardous Air Pollutants: Paper and Other Web Coating, in the
docket for this rule for the reasons for these determinations (Docket
ID Item No. EPA-HQ-OAR-2018-0416-0068).
    The revised regulatory text references ANSI/ASME PTC 19.10-1981 (40
CFR 63.3360) and ASTM D5087-02 (40 CFR 63.3165). These standards were
previously approved for this section. That approval continues without
change.
    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). The
documentation for this decision is

contained in section V.F of this preamble and the technical report,
Risk and Technology Review--Analysis of Demographic Factors for
Populations Living Near Paper and Other Web Coating Facilities, which
is available in the docket for this action (Docket ID No. EPA-HQ-OAR-
2018-0416).

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 63.3300 is amended by:
0
a. Revising the introductory text and paragraphs (a), (b), (d), (e) and
(f); and
0
b. Adding paragraphs (h) through (j).
    The revisions and additions read as follows:

Sec.  63.3300   Which of my emission sources are affected by this
subpart?

    The affected source subject to this subpart is the collection of
all web coating lines at your facility. This includes web coating lines
engaged in the coating of metal webs that are used in flexible
packaging, and web coating lines engaged in the coating of fabric
substrates for use in pressure sensitive tape and abrasive materials.
Web coating lines specified in paragraphs (a) through (g) of this
section are not part of the affected source of this subpart.
    (a) Any web coating line that is stand-alone equipment under
subpart KK of this part (National Emission Standards for Hazardous Air
Pollutants (NESHAP) for the Printing and Publishing Industry) which the
owner or operator includes in the affected source under subpart KK.
    (b) Any web coating line that is a product and packaging
rotogravure or wide-web flexographic press under subpart KK of this
part (NESHAP for the Printing and Publishing Industry) which is
included in the affected source under subpart KK.
* * * * *
    (d) Any web coating line subject to subpart EE of this part (NESHAP
for Magnetic Tape Manufacturing Operations).
    (e) Any web coating line subject to subpart SSSS of this part
(NESHAP for Surface Coating of Metal Coil).
    (f) Any web coating line subject to subpart OOOO of this part
(NESHAP for the Printing, Coating, and Dyeing of Fabrics and Other
Textiles). This includes any web coating line that coats both a paper
or other web substrate and a fabric or other textile substrate, except
for a fabric substrate used for pressure sensitive tape and abrasive
materials.
* * * * *
    (h) Any web coating line that coats both paper or a web, and
another substrate such as fabric, may comply with the subpart of this
part that applies to the predominant activity conducted on the affected
source. Predominant activity for this subpart is 90 percent of the mass
of substrate coated during the compliance period. For example, a web
coating line that coats 90 percent or more of a paper substrate, and 10
percent or less of a fabric or other textile substrate, would be
subject to this subpart and not subpart OOOO of this part. You may use
data for any reasonable time period of at least one year in determining
the relative amount of coating activity, as long as they are expected
to represent the way the source will continue to operate in the future.
You must demonstrate and document the predominant activity annually.
    (i) Any web coating line subject to this part that is modified to
include printing activities, may continue to demonstrate compliance
with this part, in lieu of demonstrating compliance with subpart KK of
this part. Any web coating line with product and packaging rotogravure
print station(s) and/or a wide-web flexographic print station(s) that
is subject to this subpart may elect to continue demonstrating
compliance with this subpart in lieu of subpart KK of this part, if the
mass of the materials applied to the line's print station(s) in

a month ever exceed 5 percent of the total mass of materials applied
onto the line during the same period.
    (j) If all of the subject web coating lines at your facility
utilize non-HAP coatings, you can become exempt from the reporting
requirements of this subpart, provided you submit a one-time report as
required in Sec.  63.3370(s) to your permitting authority documenting
the use of only non-HAP coatings.

0
4. Section 63.3310 is amended by revising the definitions of ``coating
material(s)'' and ``web coating line'' to read as follows:

Sec.  63.3310   What definitions are used in this subpart?

* * * * *
    Coating material(s) means all liquid or semi-liquid materials
(including the solids fraction of those materials as applied), such as
inks, varnishes, adhesives (including hot melt adhesives or other hot
melt materials), primers, solvents, reducers, and other materials
applied to a substrate via a web coating line. Materials used to form a
substrate or applied via vapor deposition, and dry abrasive materials
deposited on top of a coated web, are not considered coating materials.
* * * * *
    Web coating line means any number of work stations, of which one or
more applies a continuous layer of liquid or semi-liquid coating
material across the entire width or any portion of the width of a web
substrate, and any associated curing/drying equipment between an unwind
or feed station and a rewind or cutting station.
* * * * *

0
5. Section 63.3320 is amended by revising paragraphs (b) introductory
text and (b)(4) to read as follows:
    The revisions read as follows:

Sec.  63.3320   What emission standards must I meet?

* * * * *
    (b) You must limit organic HAP emissions to the level specified in
paragraph (b)(1), (2), (3), or (4) of this section for all periods of
operation, including startup, shutdown, and malfunction (SSM).
* * * * *
    (4) If you use an oxidizer to control organic HAP emissions,
operate the oxidizer such that an outlet organic HAP concentration of
no greater than 20 parts per million by volume (ppmv) on a dry basis is
achieved and the efficiency of the capture system is 100 percent.
* * * * *

0
6. Section 63.3321 is amended by revising paragraph (a) to read as
follows:

Sec.  63.3321   What operating limits must I meet?

    (a) For any web coating line or group of web coating lines for
which you use add-on control devices to demonstrate compliance with the
emission standards in Sec.  63.3320, unless you use a solvent recovery
system and conduct a liquid-liquid material balance, you must meet the
operating limits specified in Table 1 to this subpart or according to
paragraph (b) of this section. These operating limits apply to emission
capture systems and control devices used to demonstrate compliance with
this subpart, and you must establish the operating limits during the
performance test according to the requirements in Sec.  63.3360(e)(3).
You must meet the operating limits at all times after you establish
them.
* * * * *

0
7. Section 63.3330 is revised to read as follows:

Sec.  63.3330   When must I comply?

    (a) For affected sources which commenced construction or
reconstruction prior to September 19, 2019, you must comply as follows:
    (1) Before July 9, 2021, the affected coating operation(s) must be
in compliance with the applicable emission limit in Sec.  63.3320 at
all times, except during periods of SSM. On and after July 9, 2021, the
affected coating operation(s) must be in compliance with the applicable
emission limit in Sec.  63.3320 at all times, including periods of SSM.
    (2) A periodic emissions performance test must be performed by July
9, 2023, or within 60 months of the previous test, whichever is later,
and subsequent tests no later than 60 months thereafter, as required in
Sec.  63.3360. Performance testing for HAP or VOC destruction
efficiency required by state agencies can be used to meet this
requirement.
    (3) After July 9, 2021, you must electronically submit initial
notifications, notifications of compliance status, performance
evaluation reports, and performance test reports, as required in Sec.
63.3400. Semiannual compliance reports must be submitted electronically
for the first full semiannual compliance period after the template has
been available in the Compliance and Emissions Data Reporting Interface
(CEDRI) for 1 year.
    (b) For new affected sources which commenced construction or
reconstruction after September 19, 2019, you must comply as indicated
in paragraphs (b)(1) through (3) of this section. Existing affected
sources which have undergone reconstruction as defined in Sec.  63.2
are subject to the requirements for new affected sources. The costs
associated with the purchase and installation of air pollution control
equipment are not considered in determining whether the existing
affected source has been reconstructed. Additionally, the costs of
retrofitting and replacing of equipment that is installed specifically
to comply with this subpart are not considered reconstruction costs.
    (1) The coating operation(s) must be in compliance with the
applicable emission limit in Sec.  63.3320 at all times, including
periods of SSM, starting July 9, 2020, or immediately upon startup,
whichever is later.
    (2) You must complete any initial performance test required in
Sec.  63.3360 within the time limits specified in Sec.  63.7(a)(2), and
subsequent tests no later than 60 months thereafter.
    (3) You must electronically submit initial notifications,
notifications of compliance status, performance evaluation reports, and
performance test reports as required in Sec.  63.3400 starting July 9,
2020, or immediately upon startup, whichever is later. Semiannual
compliance reports must be submitted electronically for the first full
semiannual compliance period after the template has been available in
CEDRI for 1 year.

0
8. Section 63.3340 is revised to read as follows:

Sec.  63.3340   What general requirements must I meet to comply with
the standards?

    (a) Before July 9, 2021, for each existing source for which
construction or reconstruction commenced on or before September 19,
2019, you must be in compliance with the emission limits and operating
limits in this subpart at all times, except during periods of SSM. On
and after July 9, 2021, for each such source you must be in compliance
with the emission limits and operating limits in this subpart at all
times. For new and reconstructed sources for which construction or
reconstruction commenced after September 19, 2019, you must be in
compliance with the emission limits and operating limits in this
subpart at all times, starting July 9, 2020, or immediately upon
startup, whichever is later.
    (b) For affected sources as of September 19, 2019, before July 9,
2021, 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 July 9, 2021, for such sources and on July 9, 2020, or
immediately upon startup, whichever is later, for new or reconstructed
affected sources, you must always operate and maintain your 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 which 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 source.
    (c) You must conduct each performance test required by Sec.
63.3360 according to the requirements in Sec.  63.3360(e)(2) and under
the conditions 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, and nonoperation do not constitute representative conditions.
You may not conduct performance tests during periods of malfunction.
You must record the process information that is necessary to document
operating conditions during the test and explain why the conditions
represent normal operation. Upon request, you shall make available to
the Administrator such records as may be necessary to determine the
conditions of performance tests.
    (2) Representative emission capture system and add-on control
device operating conditions. You must conduct the performance test when
the emission capture system and add-on control device are operating at
a representative flow rate, and the add-on control device is operating
at a representative inlet concentration. Representative conditions
exclude periods of startup and shutdown. You may not conduct
performance tests during periods of malfunction. You must record
information that is necessary to document emission capture system and
add-on control device operating conditions during the test and explain
why the conditions represent normal operation.
    (d) Table 2 to this subpart specifies the provisions of subpart A
of this part that apply if you are subject to subpart JJJJ.

9. Section 63.3350 is amended by:
0
a. Revising paragraphs (b), (c) introductory text, (d)(1)(iii), (e)
introductory text, and (e)(2) and (4);
0
b. Redesignating paragraphs (e)(5) through (10) as paragraphs (e)(6)
through (11);
0
c. Adding new paragraph (e)(5); and
0
d. Revising newly redesignated paragraph (e)(10).
    The revisions and addition read as follows:

Sec.  63.3350   If I use a control device to comply with the emission
standards, what monitoring must I do?

* * * * *
    (b) Following the date on which the initial or periodic performance
test of a control device is completed to demonstrate continuing
compliance with the standards, you must monitor and inspect each
capture system and each control device used to comply with Sec.
63.3320. You must install and operate the monitoring equipment as
specified in paragraphs (c) and (f) of this section.
    (c) Bypass and coating use monitoring. If you own or operate web
coating lines with intermittently-controlled work stations, you must
monitor bypasses of the control device and the mass of each coating
material applied at the work station during any such bypass. If using a
control device for complying with the requirements of this subpart, you
must demonstrate that any coating material applied on a never-
controlled work station or an intermittently-controlled work station
operated in bypass mode is allowed in your compliance demonstration
according to Sec.  63.3370(o) and (p). The bypass monitoring must be
conducted using at least one of the procedures in paragraphs (c)(1)
through (4) of this section for each work station and associated dryer.
* * * * *
    (d) * * *
    (1) * * *
    (iii) You must have valid data from at least 90 percent of the
hours when the process is operated. Invalid or missing data should be
reported as a deviation in the semiannual compliance report.
* * * * *
    (e) Continuous parameter monitoring system (CPMS). If you are using
a control device to comply with the emission standards in Sec.
63.3320, you must install, operate, and maintain each CPMS specified in
paragraphs (e)(10) and (11) and (f) of this section according to the
requirements in paragraphs (e)(1) through (9) of this section. You must
install, operate, and maintain each CPMS specified in paragraph (c) of
this section according to paragraphs (e)(5) through (8) of this
section.
* * * * *
    (2) You must have valid data from at least 90 percent of the hours
when the process operated.
* * * * *
    (4) You must determine the block 3-hour average of all recorded
readings for each operating period. To calculate the average for each
3-hour averaging period, you must have at least two of three of the
hourly averages for that period using only average values that are
based on valid data (i.e., not from out-of-control periods).
    (5) Except for temperature sensors, you must develop a quality
control program that must contain, at a minimum, a written protocol
that describes the procedures for each of the operations in Sec.
63.3350(e)(5)(i) through (vi). The owner or operator shall keep these
written procedures on record for the life of the affected source or
until the affected source is no longer subject to the provisions of
this part, to be made available for inspection, upon request, by the
Administrator. If the performance evaluation plan is revised, the owner
or operator shall keep previous (i.e., superseded) versions of the

                                          the coated web or otherwise
                                          not emitted to the atmosphere

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

    (b) Control Device. If you are using a control device to comply
with the emission standards in Sec.  63.3320, you are not required to
conduct a performance test to demonstrate compliance if one or more of
the criteria in paragraphs (b)(1) through (3) of this section are met.
    (1) The control device is equipped with continuous emission
monitoring systems (CEMS) for determining inlet and outlet total
organic volatile matter concentration and meeting the requirements of
Performance Specification 6, 8, or 9 in Appendix B to 40 CFR Part 60
and capture efficiency

has been determined in accordance with the requirements of this subpart
such that an overall organic HAP control efficiency can be calculated,
and the CEMS are used to demonstrate continuous compliance in
accordance with Sec.  63.3350; or
    (2) You have met the requirements of Sec.  63.7(h) (for waiver of
performance testing); or
    (3) The control device is a solvent recovery system and you comply
by means of a monthly liquid-liquid material balance.
    (c) * * *
    (1) * * *
    (i) Include each organic HAP determined to be present at greater
than or equal to 0.1 mass percent for Occupational Safety and Health
Administration (OSHA)-defined carcinogens as specified in section A.6.4
of appendix A to 29 CFR 1910.1200 and greater than or equal to 1.0 mass
percent for other organic HAP compounds.
* * * * *
    (2) Method 24. For coatings, determine the volatile organic content
as mass fraction of nonaqueous volatile matter and use it as a
substitute for organic HAP using Method 24 of appendix A-7 to 40 CFR
part 60. The Method 24 determination may be performed by the
manufacturer of the coating and the results provided to you. One of the
voluntary consensus standards in paragraphs (c)(2)(i) through (v) of
this section may be used as an alternative to using Method 24.
    (i) ASTM D1963-85 (Reapproved 1996), (incorporated by reference,
see Sec.  63.14);
    (ii) ASTM D2111-10 (Reapproved 2015), (incorporated by reference,
see Sec.  63.14);
    (iii) ASTM D2369-10 (Reapproved 2015)\e\, (incorporated by
reference, see Sec.  63.14);
    (iv) ASTM D2697-03 (Reapproved 2014), (incorporated by reference,
see Sec.  63.14); and
    (v) ASTM D6093-97 (Reapproved 2016), (incorporated by reference,
see Sec.  63.14).
    (3) Formulation data. You may use formulation data to determine the
organic HAP mass fraction of a coating material. Formulation data may
be provided to the owner or operator by the manufacturer of the
material. In the event of an inconsistency between Method 311 (appendix
A to this part) test data and a facility's formulation data, and the
Method 311 test value is higher, the Method 311 data will govern.
Formulation data may be used provided that the information represents
all organic HAP present at a level equal to or greater than 0.1 percent
for OSHA-defined carcinogens as specified in section A.6.4 of appendix
A to 29 CFR 1910.1200 and equal to or greater than 1.0 percent for
other organic HAP compounds in any raw material used.
    (4) As-applied organic HAP mass fraction. If the as-purchased
coating material is applied to the web without any solvent or other
material added, then the as-applied organic HAP mass fraction is equal
to the as-purchased organic HAP mass fraction. Otherwise, the as-
applied organic HAP mass fraction must be calculated using Equation 4
of Sec.  63.3370.
    (d) * * *
    (1) Method 24. You may determine the volatile organic and coating
solids mass fraction of each coating applied using Method 24 (appendix
A-7 to 40 CFR part 60). The Method 24 determination may be performed by
the manufacturer of the material and the results provided to you. When
using volatile organic compound content as a surrogate for HAP, you may
also use ASTM D3960-98, (incorporated by reference, see Sec.  63.14) as
an alternative to Method 24. If these values cannot be determined using
either of these methods, you must submit an alternative technique for
determining their values for approval by the Administrator.
    (2) Formulation data. You may determine the volatile organic
content and coating solids content of a coating material based on
formulation data and may rely on volatile organic content data provided
by the manufacturer of the material. In the event of any inconsistency
between the formulation data and the results of Method 24 of appendix
A-7 to 40 CFR part 60 and the Method 24 results are higher, the results
of Method 24 will govern.
    (3) As-applied volatile organic content and coating solids content.
If the as-purchased coating material is applied to the web without any
solvent or other material added, then the as-applied volatile organic
content is equal to the as-purchased volatile content and the as-
applied coating solids content is equal to the as-purchased coating
solids content. Otherwise, the as-applied volatile organic content must
be calculated using Equation 5 to Sec.  63.3370(c)(4) and the as-
applied coating solids content must be calculated using Equation 6 to
Sec.  63.3370(d).
    (e) * * *
    (1) Initial performance test. An initial performance test to
establish the destruction or removal efficiency of the control device
used to comply with the emission standards in Sec.  63.3320 must be
conducted such that control device inlet and outlet testing is
conducted simultaneously, and the data are reduced in accordance with
the test methods and procedures in paragraphs (e)(1)(i) through (ix) of
this section. You must conduct three test runs as specified in Sec.
63.7(e)(3), and each test run must last at least 1 hour.
    (i) Method 1 or 1A of appendix A-1 to 40 CFR part 60 must be used
for sample and velocity traverses to determine sampling locations.
    (ii) Method 2, 2A, 2C, 2D, or 2F of appendix A-1 to 40 CFR part 60,
or Method 2G of appendix A-2 to 40 CFR part 60 must be used to
determine gas volumetric flow rate.
    (iii) Method 3, 3A, or 3B of appendix A-2 to 40 CFR part 60 must be
used 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 Part 10, (incorporated by reference, see Sec.
63.14).
    (iv) Method 4 of appendix A-3 to 40 CFR part 60 must be used to
determine stack gas moisture.
    (v) Methods for determining the gas volumetric flow rate, dry
molecular weight, and stack gas moisture must be performed, as
applicable, during each test run.
    (vi) Method 25 or 25A of appendix A-7 to 40 CFR part 60 must be
used to determine total gaseous non-methane organic matter
concentration. Use the same test method for both the inlet and outlet
measurements which must be conducted simultaneously. You must submit
notice of the intended test method to the Administrator for approval
along with notification of the performance test required under Sec.
63.7(b). You must use Method 25A if any of the conditions described in
paragraphs (e)(1)(vi)(A) through (D) of this section apply to the
control device.
    (A) The control device is not an oxidizer.
    (B) The control device is an oxidizer but an exhaust gas volatile
organic matter concentration of 50 ppmv or less is required to comply
with the emission standards in Sec.  63.3320; or
    (C) The control device is an oxidizer but the volatile organic
matter concentration at the inlet to the control system and the
required level of control are such that they result in exhaust gas
volatile organic matter concentrations of 50 ppmv or less; or
    (D) The control device is an oxidizer but because of the high
efficiency of the control device the anticipated volatile organic
matter concentration at the

control device exhaust is 50 ppmv or less, regardless of inlet
concentration.
    (vii) Except as provided in Sec.  63.7(e)(3), each performance test
must consist of three separate runs with each run conducted for at
least 1 hour under the conditions that exist when the affected source
is operating under normal operating conditions. For the purpose of
determining volatile organic compound concentrations and mass flow
rates, the average of the results of all the runs will apply.
    (viii) Volatile organic matter mass flow rates must be determined
for each run specified in paragraph (e)(1)(vii) of this section using
Equation 1:
[GRAPHIC] [TIFF OMITTED] TR09JY20.023

Where:

Mf = Total organic volatile matter mass flow rate,
kilograms (kg)/hour (h).
Qsd = Volumetric flow rate of gases entering or exiting
the control device, as determined according to paragraph (e)(1)(ii)
of this section, dry standard cubic meters (dscm)/h.
Cc = Concentration of organic compounds as carbon, ppmv.
12.0 = Molecular weight of carbon.
0.0416 = Conversion factor for molar volume, kg-moles per cubic
meter (mol/m\3\) (@293 Kelvin (K) and 760 millimeters of mercury
(mmHg)).

    (ix) For each run, emission control device destruction or removal
efficiency must be determined using Equation 2:
[GRAPHIC] [TIFF OMITTED] TR09JY20.000

Where:

E = Organic volatile matter control efficiency of the control
device, percent.
Mfi = Organic volatile matter mass flow rate at the inlet
to the control device, kg/h.
Mfo = Organic volatile matter mass flow rate at the
outlet of the control device, kg/h.

    (x) The control device destruction or removal efficiency is
determined as the average of the efficiencies determined in the test
runs and calculated in Equation 2.
    (2) Process information. You must record such process information
as may be necessary to determine the conditions in existence at the
time of the performance test. Representative conditions exclude periods
of startup and shutdown. You may not conduct performance tests during
periods of malfunction. You must record the process information that is
necessary to document operating conditions during the test and include
in such record an explanation to support that such conditions represent
normal operation. Upon request, you shall make available to the
Administrator such records as may be necessary to determine the
conditions of performance tests.
    (3) Operating limits. If you are using one or more add-on control
device other than a solvent recovery system for which you conduct a
liquid-liquid material balance to comply with the emission standards in
Sec.  63.3320, you must establish the applicable operating limits
required by Sec.  63.3321. These operating limits apply to each add-on
emission control device, and you must establish the operating limits
during the performance test required by paragraph (e) of this section
according to the requirements in paragraphs (e)(3)(i) and (ii) of this
section.
    (i) Thermal oxidizer. If your add-on control device is a thermal
oxidizer, establish the operating limits according to paragraphs
(e)(3)(i)(A) and (B) of this section.
    (A) During the performance test, you must monitor and record the
combustion temperature at least once every 15 minutes during each of
the three test runs. You must monitor the temperature in the firebox of
the thermal oxidizer or immediately downstream of the firebox before
any substantial heat exchange occurs.
    (B) Use the data collected during the performance test to calculate
and record the average combustion temperature maintained during the
performance test. Maintain the 3-hour average combustion temperature no
more than 50 degrees Fahrenheit lower than this average combustion
temperature.
    (ii) Catalytic oxidizer. If your add-on control device is a
catalytic oxidizer, establish the operating limits according to
paragraphs (e)(3)(ii)(A) and (B) or paragraphs (e)(3)(ii)(C) and (D) of
this section.
    (A) During the performance test, you must monitor and record the
temperature just before the catalyst bed and the temperature difference
across the catalyst bed at least once every 15 minutes during each of
the three test runs.
    (B) Use the data collected during the performance test to calculate
and record the average temperature just before the catalyst bed and the
average temperature difference across the catalyst bed maintained
during the performance test. Maintain the 3-hour average combustion
temperature no more than 50 degrees Fahrenheit lower than this average
combustion temperature or maintain the 3-hour average temperature
difference across the catalyst bed at no less than 80 percent of this
average temperature differential, provided that the minimum temperature
is always 50 degrees Fahrenheit above the catalyst's ignition
temperature.
    (C) 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
(e)(3)(ii)(D) of this section. During the performance test, you must
monitor and record the temperature just before the catalyst bed at
least once every 15 minutes during each of the three test runs. Use the
data collected during the performance test to calculate and record the
average temperature just before the catalyst bed during the performance
test. Maintain the 3-hour average combustion temperature no more than
50 degrees Fahrenheit lower than this average combustion temperature.
    (D) You must develop and implement an inspection and maintenance
plan for your catalytic oxidizer(s) for which you elect to monitor
according to paragraph (e)(3)(ii)(C) of this section. The plan must
address, at a minimum, the elements specified in paragraphs
(e)(3)(ii)(D)(1) through (3) of this section.

    (1) Annual sampling and analysis of the catalyst activity (i.e.,
conversion efficiency) following the manufacturer's or catalyst
supplier's recommended procedures,
    (2) Monthly inspection of the oxidizer system including the burner
assembly and fuel supply lines for problems, and
    (3) Annual internal and monthly external visual inspection of the
catalyst bed to check for channeling, abrasion, and settling. If
problems are found, you must take corrective action consistent with the
manufacturer's recommendations and conduct a new performance test to
determine destruction efficiency in accordance with this section.
    (4) Control Destruction Efficiency Curve Development. If you are
using one or more add-on control devices other than a solvent recovery
system for which you conduct a liquid-liquid material balance to comply
with the emission standards in Sec.  63.3320, you may establish a
control destruction efficiency curve for use in estimating emissions
that occur during deviations of the 3-hour operating parameters. This
curve can be generated using test data or manufacturer's data that

    (f) Capture efficiency. If you demonstrate compliance by meeting
the requirements of Sec.  63.3370(f), (g), (h), (i), (j)(2), (l),
(o)(2) or (3), or (q), you must determine capture efficiency using the
procedures in paragraph (f)(1), (2), or (3) of this section, as
applicable.

    (g) Volatile matter retained in the coated web or otherwise not
emitted to the atmosphere. You may choose to take into account the mass
of volatile matter retained in the coated web after curing or drying or
otherwise not emitted to the atmosphere when determining compliance
with the emission standards in Sec.  63.3320. If you choose this
option, you must develop a site- and product-specific emission factor
(EF) and determine the amount of volatile matter retained in the coated
web or otherwise not emitted using Equation 3 to Sec.  63.3360(g)(1).
The EF must be developed by conducting a performance test using an
approved EPA test method, or alternative approved by the Administrator
by obtaining the average of a three-run test. You may additionally use
manufacturer's emissions test data (as long as it replicates the
facility's coating formulation and operating conditions), or a mass-
balance type approach using a modified Method 24 (including ASTM D5403-
93 for radiation-cureable coatings). The EF should equal the proportion
of the mass of volatile organics emitted to the mass of volatile
organics in the coating materials evaluated. You may use the EF in your
compliance calculations only for periods that the work station(s) was
(were) used to make the product, or a similar product, corresponding to
that produced during the performance test. You must develop a separate
EF for each group of different products that you choose to utilize an
EF for calculating emissions by conducting a separate performance test
for that group of products. You must conduct a periodic performance
test to re-establish the EF if there is a change in coating
formulation, operating conditions, or other change that could
reasonably be expected to increase emissions since the time of the last
test that was used to establish the EF.

Where:

Mvret = Mass of volatile matter retained in the coated
web after curing or drying, or otherwise not emitted to the
atmosphere, kg.
Cvi = Volatile organic content of coating material, i,
expressed as a mass fraction, kg/kg.
Mi = Mass of as-purchased coating material, i, applied in
a month, kg.
q = Number of different materials added to the coating material.
Cvij = Volatile organic content of material, j, added to
as-purchased coating material, i, expressed as a mass fraction, kg/
kg.
Mij = Mass of material, j, added to as-purchased coating
material, i, in a month, kg.
EFi = Volatile organic matter site- and product-specific
emission factor (three-run average determined from performance
testing, evaluated as proportion of mass volatile organics emitted
to mass of volatile organics in the coatings used during the
performance test).

Sec.  63.3370  How do I demonstrate compliance with the emission
standards?

    You must demonstrate compliance each month with the emission
limitations in Sec.  63.3320(b)(1) through (4). For each monthly
demonstration, you may apply any combination of the emission
limitations to each of your web coating lines individually, to each of
one or more groupings of your lines (including a single grouping
encompassing all lines of your affected source), or to any combination
of individual and grouped lines, so long as each web coating line is
included in the compliance demonstration for the month (i.e., you are
not required to apply the same emission limitation to each of the
individual lines or groups of lines). You may change the emission
limitation that you apply each month to your individual or grouped
lines, and you may change line groupings for your monthly compliance
demonstration.
    (a) A summary of how you must demonstrate compliance follows:

efficiency of at least 95 percent at an existing affected source and at
least 98 percent at a new affected source for each month, or operate a
capture system and oxidizer so that an outlet organic HAP concentration
of no greater than 20 ppmv on a dry basis is achieved as long as the

on a monthly average as-applied basis. If the affected source operates
more than one capture system, more than one control device, one or more
never-controlled work stations, or one or more intermittently-
controlled work stations, then you must demonstrate compliance in
accordance with the provisions of paragraph (o) of this section.

are controlled by a solvent recovery device or the procedure in
paragraph (l) of this section when emissions are controlled by an

accordance with paragraph (m) of this section. If the affected source
operates more than one capture system, more than one control device,
one or more never-controlled work stations, or one or more
intermittently-controlled work stations, then you must demonstrate
compliance in accordance with the provisions of paragraph (o) of this
section. Otherwise, the owner or operator must demonstrate compliance

from the affected source are controlled by a solvent recovery device or
the procedure in paragraph (l) of this section when emissions are
controlled by an oxidizer.

provides the procedures and calculations for determining monthly
allowable organic HAP emissions for use in demonstrating compliance in
accordance with paragraph (d), (i), (j)(1)(x)(D), (j)(2)(xi)(D), or

coating material applied at greater than or equal to 20 mass percent
coating solids and the amount of coating material applied at less than

kg coating solids at an existing affected source or 0.08 kg organic HAP
per kg coating solids at a new affected source, and coating material
applied at less than 20 mass percent coating solids complying with 4
mass percent organic HAP at an existing affected source and 1.6 mass-
percent organic HAP at a new affected source as follows:
    (1) Determine the as-purchased mass of each coating material
applied each month.
    (2) Determine the as-purchased coating solids content of each
coating material applied each month in accordance with Sec.
63.3360(d)(1).
    (3) Determine the as-purchased mass fraction of each coating
material which was applied at 20 mass percent or greater coating solids
content on an as-applied basis.
    (4) Determine the total mass of each solvent, diluent, thinner, or
reducer added to coating materials which were applied at less than 20
mass percent coating solids content on an as-applied basis each month.
