AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The U.S. Environmental Protection Agency (EPA) is taking final 
action on the residual risk and technology reviews (RTRs) conducted for 
the Surface Coating of Automobiles and Light-Duty Trucks (ALDT); 
Surface Coating of Miscellaneous Metal Parts and Products (MMPP); and 
the Surface Coating of Plastic Parts and Products (PPP) source 
categories regulated under national emission standards for hazardous 
air pollutants (NESHAP). These final amendments also address emissions 
during periods of startup, shutdown, and malfunction (SSM); electronic 
reporting of performance test results and compliance reports; the 
addition of EPA Method 18 and updates to several measurement methods; 
and the addition of requirements for periodic performance testing. 
Several miscellaneous technical amendments were also made to improve 
the clarity of the rule requirements. We are making no revisions to the 
numerical emission limits based on these risk analyses or technology 
reviews. This notice also finalizes technical corrections to the NESHAP 
for Surface Coating of Large Appliances; NESHAP for Printing, Coating, 
and Dyeing of Fabrics and Other Textiles; and NESHAP for Surface 
Coating of Metal Furniture.

DATES: This final rule is effective on July 8, 2020. The incorporation 
by reference (IBR) of certain publications listed in the rule is 
approved by the Director of the Federal Register as of July 8, 2020. 
The incorporation by reference of certain other publications listed in 
the rule was approved by the Director of the Federal Register as of

affected, you should examine the applicability criteria in the 
appropriate NESHAP. If you have any questions regarding the 
applicability of any aspect of these NESHAP, please contact the 
appropriate person listed in the preceding FOR FURTHER INFORMATION 
CONTACT section of this preamble.

B. Where can I get a copy of this document and other related 
information?

    In addition to being available in the docket, an electronic copy of 
this final action will also be available on the internet. Following 
signature by the EPA Administrator, the EPA will post a copy of this 
final action at: https://www.epa.gov/stationary-sources-air-pollution/surface-coating-automobiles-and-light-duty-trucks-national-emission, 
https://www.epa.gov/stationary-sources-air-pollution/surface-coating-miscellaneous-metal-parts-and-products-national, and https://www.epa.gov/stationary-sources-air-pollution/surface-coating-plastic-parts-and-products-national-emission. Following publication in the 
Federal Register, the EPA will post the Federal Register version and 
key technical documents at these same websites.
    Additional information is available on the RTR website at https://www.epa.gov/stationary-sources-air-pollution/risk-and-technology-review-national-emissions-standards-hazardous. This information 
includes an overview of the RTR program and links to project websites 
for the RTR source categories.

C. Judicial Review and Administrative Reconsideration

    Under Clean Air Act (CAA) section 307(b)(1), judicial review of 
this final action is available only by filing a petition for review in 
the United States Court of Appeals for the District of Columbia Circuit 
(the Court) by September 8, 2020. Under CAA section 307(b)(2), the 
requirements established by this final rule may not be challenged 
separately in any civil or criminal proceedings brought by the EPA to 
enforce the requirements.
    Section 307(d)(7)(B) of the CAA further provides that only an 
objection to a rule or procedure which was raised with reasonable 
specificity during the period for public comment (including any public 
hearing) may be raised during judicial review. This section also 
provides a mechanism for the EPA to reconsider the rule if the person 
raising an objection can demonstrate to the Administrator that it was 
impracticable to raise such objection within the period for public 
comment or if the grounds for such objection arose after the period for 
public comment (but within the time specified for judicial review) and 
if such objection is of central relevance to the outcome of the rule. 
Any person seeking to make such a demonstration should submit a 
Petition for Reconsideration to the Office of the Administrator, U.S. 
EPA, Room 3000, WJC South Building, 1200 Pennsylvania Ave. NW, 
Washington, DC 20460, with a copy to both the person(s) listed in the 
preceding FOR FURTHER INFORMATION CONTACT section, and the Associate 
General Counsel for the Air and Radiation Law Office, Office of General 
Counsel (Mail Code 2344A), U.S. EPA, 1200 Pennsylvania Ave. NW, 
Washington, DC 20460.

II. Background

A. What is the statutory authority for this action?

    Section 112 of the CAA establishes a two-stage regulatory process 
to address emissions of hazardous air pollutants (HAP) from stationary 
sources. In the first stage, we must identify categories of sources 
emitting one or more of the HAP listed in CAA section 112(b) and then 
promulgate technology-based NESHAP for those sources. ``Major sources'' 
are those that emit, or have the potential to emit, any single HAP at a 
rate of 10 tons per year (tpy) or more, or 25 tpy or more of any 
combination of HAP. For major sources, these standards are commonly 
referred to as maximum achievable control technology (MACT) standards 
and must reflect the maximum degree of emission reductions of HAP 
achievable (after considering cost, energy requirements, and non-air 
quality health and environmental impacts). In developing MACT 
standards, CAA section 112(d)(2) directs the EPA to consider the 
application of measures, processes, methods, systems, or techniques, 
including, but not limited to, those that: (1) Reduce the volume of or 
eliminate HAP emissions through process changes, substitution of 
materials, or other modifications; (2) enclose systems or processes to 
eliminate emissions; (3) collect, capture, or treat HAP when released 
from a process, stack, storage, or fugitive emissions point; (4) are 
design, equipment, work practice, or operational standards; or (5) any 
combination of the above.
    For these MACT standards, the statute specifies certain minimum 
stringency requirements, which are referred to as MACT floor 
requirements, and which may not be based on cost considerations. See 
CAA section 112(d)(3). For new sources, the MACT floor cannot be less 
stringent than the emission control achieved in practice by the best-
controlled similar source. The MACT standards for existing sources can 
be less stringent than floors for new sources, but they cannot be less 
stringent than the average emission limitation achieved by the best-
performing 12 percent of existing sources in the category or 
subcategory (or the best-performing five sources for categories or 
subcategories with fewer than 30 sources). In developing MACT 
standards, we must also consider control options that are more 
stringent than the floor under CAA section 112(d)(2). We may establish 
standards more stringent than the floor, based on the consideration of 
the cost of achieving the emissions reductions, any non-air quality 
health and environmental impacts, and energy requirements.
    In the second stage of the regulatory process, the CAA requires the 
EPA to undertake two different analyses, which we refer to as the 
technology review and the residual risk review. Under the technology 
review, we must review the technology-based standards and revise them 
``as necessary (taking into account developments in practices, 
processes, and control technologies)'' no less frequently than every 8 
years pursuant to CAA section 112(d)(6). Under the residual risk 
review, we must evaluate the risk to public health remaining after 
application of the technology-based standards and revise the standards, 
if necessary, to provide an ample margin of safety to protect public 
health or to prevent, taking into consideration costs, energy, safety, 
and other relevant factors, an adverse environmental effect. The 
residual risk review is required within 8 years after promulgation of 
the technology-based standards, pursuant to CAA section 112(f). In 
conducting the residual risk review, if the EPA determines that the 
current standards provide an ample margin of safety to protect public 
health, it is not necessary to revise the MACT standards pursuant to 
CAA section 112(f).\1\ For more information on the statutory authority 
for this rule, see the proposal preamble (84 FR 58936, November 1, 
2019) and the memorandum, CAA Section 112 Risk and Technology Reviews:

B. What are the source categories and how do the NESHAP regulate their 
HAP emissions?

1. What is the surface coating of ALDT source category and how does the 
current NESHAP regulate its HAP emissions?
    The NESHAP for the ALDT source category was promulgated on April 
26, 2004 (69 FR 22602), and is codified at 40 CFR part 63, subpart 
IIII. Technical corrections and clarifying amendments were promulgated 
on December 22, 2006 (71 FR 76922), and April 24, 2007 (72 FR 20227). 
The ALDT NESHAP applies to any affected source that is a major source, 
is located at a major source, or is part of a major source of HAP 
emissions. The affected source is any coating operation that applies 
topcoats to new automobile or new light-duty truck bodies or body parts 
for new automobiles or new light-duty trucks and/or coatings to other 
new motor vehicle bodies or body parts for other new motor vehicles; 
parts intended for use in new automobiles, new light-duty trucks, or 
other new motor vehicles; or aftermarket repair or replacement parts 
for automobiles, light-duty trucks, or other motor vehicles. The source 
category covered by this MACT standard currently comprises 43 
facilities.
    The ALDT NESHAP (40 CFR 63.3176) defines an ``automobile'' as ``a 
motor vehicle designed to carry up to eight passengers, excluding vans, 
sport utility vehicles, and motor vehicles designed primarily to 
transport light loads of property,'' and defines ``light-duty truck'' 
as ``vans, sport utility vehicles, and motor vehicles designed 
primarily to transport light loads of property with gross vehicle 
weight rating of 8,500 lbs [pounds] or less.''
    The ALDT NESHAP defines a ``coating'' as ``a material that is 
applied to a substrate for decorative, protective or functional 
purposes. Such materials include, but are not limited to, paints, 
sealants, caulks, inks, adhesives, primers, deadeners, and maskants. 
Decorative, protective, or functional materials that consist only of 
protective oils for metal, acids, bases, or any combination of these 
substances are not considered coatings for the purposes of this 
subpart.'' (40 CFR 63.3176).
    This source category is further described in the November 1, 2019, 
RTR proposal. See 84 FR 58941.
    The primary HAP emitted from ALDT surface coating operations are 
organic HAP and include toluene, xylene, glycol ethers, methyl isobutyl 
ketone (MIBK), ethyl benzene, and methanol. The HAP emissions are from 
coating application and drying and curing ovens in the ALDT surface 
coating operations. Some emissions occur from the cleaning of spray 
booths and equipment. In most cases, HAP emissions from surface 
preparation, storage, and handling are relatively small (i.e., not 
quantifiable) for this source category. Although inorganic HAP are 
reported components of coatings, no inorganic HAP are emitted because 
of the use of high efficiency spray equipment and filters on coating 
spray application operations.
    The NESHAP specifies numerical emission limits for existing sources 
and for new and reconstructed sources for organic HAP emissions from 
(1) electrodeposition primer, primer-surfacer, topcoat, final repair, 
glass bonding primer, and glass bonding adhesive operations plus all 
coatings and thinners, except for deadener materials and for adhesive 
and sealer materials that are not components of glass bonding systems, 
used in coating operations; (2) primer-surfacer, topcoat, final repair, 
glass bonding primer, and glass bonding adhesive operation plus all 
coatings and thinners, except for deadener materials and for adhesive 
and sealer materials that are not components of glass bonding systems, 
used in coating operations; (3) adhesives and sealers, other than glass 
bonding adhesive materials; and (4) deadener materials.
    The specific organic HAP emission limits are in 40 CFR 63.3090 (for 
new and reconstructed sources) and 40 CFR 63.3091 (for existing 
sources), and the operating limits are in 40 CFR 63.3093. The emission 
limits and operating limits are summarized in Tables 2 and 3, 
respectively, of the memorandum titled Technology Review for Surface 
Coating Operations in the Automobiles and Light-Duty Trucks Source 
Category, in the ALDT Docket.
    Compliance with the ALDT NESHAP emission limits can be achieved 
using several different options, including a compliant material option, 
an emission rate without add-on controls option (emissions averaging 
option), and an emission rate with add-on controls option. For bake 
ovens used to cure electrodeposition primers, an alternative is to 
capture the emissions and duct them to a control device having a 
destruction or removal efficiency of at least 95 percent. Facilities 
that have multiple paint lines may choose to group operations from two 
or more paint lines together to demonstrate compliance, or to make a 
separate compliance demonstration for the operations from each paint 
line.
    All ALDT facilities must develop and implement a work practice plan 
to minimize organic HAP emissions from the storage, mixing, and 
conveying of coatings, thinners, and cleaning materials used in, and 
waste materials generated by, the coating operations. The plan must 
specify practices and procedures to ensure that a set of minimum work 
practices specified in the NESHAP are implemented.
    Those ALDT facilities using add-on controls to comply with the 
NESHAP must also comply with site-specific operating limits for the 
emission capture and control system. These operating limits are 
established during the compliance test for the emission capture system 
and add-on control device. Alternatively, emission capture systems can 
meet design and air flow specifications to qualify as a permanent total 
enclosure with 100-percent capture efficiency.
2. What is the surface coating of MMPP source category and how does the 
current NESHAP regulate its HAP emissions?
    The MMPP NESHAP was promulgated on January 2, 2004 (69 FR 130), and 
is codified at 40 CFR part 63, subpart MMMM. Technical corrections to 
the final rule were published on April 26, 2004 (69 FR 22602), and 
December 22, 2006 (71 FR 76922). The MMPP NESHAP applies to owners or 
operators of metal parts and products surface coating operations at 
facilities that are major sources of HAP. The source category covered 
by this MACT standard currently comprises 368 facilities.
    The MMPP include, but are not limited to, metal components of the 
following types of products as well as the products themselves: Motor 
vehicle parts and accessories, bicycles and sporting goods, 
recreational vehicles, extruded aluminum structural components, 
railroad cars, heavy-duty trucks, medical equipment, lawn and garden 
equipment, electronic equipment, magnet wire, steel drums, industrial 
machinery, metal pipes, and numerous other industrial, household, and 
consumer products. The MMPP NESHAP does not apply to any surface 
coating or coating operation that meets the applicability criteria of 
any one of 11 other surface coating NESHAP, e.g., surface coating of 
metal components of wood furniture (subpart JJ of 40 CFR part 63), 
surface coating of metal components of large appliances (subpart NNNN 
of 40 CFR part 63), and surface coating of metal components of ALDT

[[Page 41105]]

(subpart IIII of 40 CFR part 63). See 40 CFR 63. 3881(c) for a list of 
exclusions to the MMPP source category.
    This source category is further described in the November 1, 2019, 
RTR proposal. See 84 FR 58942.
    The primary HAP emitted from MMPP surface coating operations are 
organic HAP and include xylenes, toluene, glycol ethers, ethyl benzene, 
MIBK, methanol, ethylene glycol, and dimethyl phthalate. The majority 
of organic HAP emissions can be attributed to the application, drying, 
and curing of coatings.
    Inorganic HAP emissions were considered in the development of the 
MMPP NESHAP, and the EPA determined that inorganic HAP emissions would 
be very low based on the coating application techniques in place at the 
time of the rule development. Given the combination of very low usage 
of coatings containing inorganic HAP in this source category, and the 
current and expected continued use of controls (dry filters and 
waterwash systems on spray booths and high efficiency equipment) to 
reduce overspray emissions, the EPA concluded that levels of inorganic 
HAP emissions did not warrant federal regulation because those 
regulations would increase regulatory burden but not be expected to 
result in additional emissions reduction.
    The MMPP NESHAP establishes the organic HAP emissions limits for 
existing sources and for new and reconstructed sources for organic HAP 
emissions for five subcategories. The five subcategories are (1) 
general use coating, (2) high performance coating, (3) magnet wire 
coating, (4) rubber-to-metal coating, and (5) extreme performance 
fluoropolymer coating.
    Compliance can be demonstrated with a compliant coatings option, 
where all coatings used have organic HAP contents that individually 
meet the organic HAP emissions limit, and all thinners and cleaning 
materials contain no organic HAP; an emission rate without add-on 
controls option, where the organic HAP emission rate, calculated as a 
rolling 12-month emission rate and determined on a monthly basis, is 
equal to or less than the organic HAP emissions limit; or an emission 
rate with add-on controls option, where the organic HAP emission rate, 
calculated as a rolling 12-month emissions rate and determined on a 
monthly basis, taking into account the emissions reduction achieved 
through the use of one or more emissions capture and control devices, 
is equal to or less than the organic HAP emissions limit. A facility 
using the add-on control option must also comply with work practice 
standards to minimize organic HAP emissions from the storage, mixing, 
and conveying of coatings, thinners, cleaning materials, and waste 
materials associated with the coating operation(s) and must also comply 
with operating limits for the emissions capture systems and add-on 
control devices.
    The specific organic HAP emission limits for each coating 
subcategory can be found in 40 CFR 63.3890 and the operating limits in 
40 CFR 63.3892. The emission limits and operating limits are summarized 
in Tables 4 and 5, respectively, of the memorandum titled Technology 
Review for Surface Coating Operations in the Miscellaneous Metal Parts 
and Products Category.
3. What is the surface coating of PPP source category and how does the 
current NESHAP regulate its HAP emissions?
    The NESHAP for the PPP source category was promulgated on April 19, 
2004 (69 FR 20968), and is codified at 40 CFR part 63, subpart PPPP. 
Technical corrections to the final rule were published on December 22, 
2006 (71 FR 76922), and April 24, 2007 (72 FR 20227). The PPP NESHAP 
applies to owners or operators of PPP surface coating operations at 
facilities that are major sources of HAP. The PPP include, but are not 
limited to, plastic components of the following types of products as 
well as the products themselves: Motor vehicle parts and accessories 
for automobiles, trucks, recreational vehicles; sporting and 
recreational goods; toys; business machines; laboratory and medical 
equipment; and household and other consumer products. The PPP NESHAP 
does not apply to the surface coating or coating operations that meet 
the applicability criteria of any of 11 other surface coating NESHAP, 
e.g., surface coating of plastic components of wood furniture (subpart 
JJ of 40 CFR part 63), surface coating of plastic components of large 
appliances (subpart NNNN of 40 CFR part 63), and surface coating of 
plastic components of ALDT (subpart IIII of 40 CFR part 63). See 40 CFR 
63. 4481(c) for a list of exclusions to the PPP source category.
    This source category is further described in the November 1, 2019, 
RTR proposal. See 84 FR 58943.
    The primary HAP emitted from PPP surface coating operations are 
organic HAP and, based on the 2011 National Emission Inventory (NEI), 
include xylene, toluene, MIBK, ethylbenzene, styrene, glycol ethers, 
and methanol, in order of decreasing emissions. These compounds account 
for about 96 percent of the nationwide HAP emissions from this source 
category, based on an analysis of the NEI. The source category covered 
by this MACT standard currently comprises 125 facilities.
    No inorganic HAP are currently associated with the coatings used in 
this source category, based on the data in the NEI.
    The PPP NESHAP specifies numerical emission limits for existing 
sources and for new and reconstructed sources for organic HAP 
emissions. The final rule contains four subcategories: (1) General use 
coating, (2) thermoplastic olefin coating, (3) automotive lamp coating, 
and (4) assembled on-road vehicle coating.
    Compliance can be demonstrated with a compliant material option, 
where the HAP content of each coating used is less than or equal to the 
applicable organic HAP emissions limit and each thinner, additive, and 
cleaning material uses no organic HAP; an emission rate without add-on 
controls option, where the organic HAP emission rate, calculated as a 
rolling 12-month emission rate and determined on a monthly basis, is 
equal to or less than the organic HAP emissions limit; or an emission 
rate with add-on controls option, where the organic HAP emission rate, 
calculated as a rolling 12-month emissions rate and determined on a 
monthly basis, taking into account the emissions reduction achieved 
through the use of one or more emissions capture and control devices, 
is equal to or less than the organic HAP emissions limit. A facility 
using the add-on control option must also comply with work practice 
standards to minimize organic HAP emissions from the storage, mixing, 
and conveying of coatings, thinners, cleaning materials, and waste 
materials associated with the coating operation(s) and must also comply 
with operating limits for the emissions capture systems and add-on 
control devices.
    The specific organic HAP emission limits for each coating 
subcategory can be found in 40 CFR 63.4490 and the operating limits in 
40 CFR 63.4492. The organic HAP emission limits and operating limits 
are summarized in Tables 2 and 3, respectively, of the memorandum 
titled Technology Review for the Plastic Parts and Products Surface 
Coating Operations Source Category.

[[Page 41106]]

4. What are the surface coating of large appliances; printing, coating, 
and dyeing of fabrics and other textiles; and surface coating of metal 
furniture source categories and how do the current NESHAP regulate 
their HAP emissions?
    The three source categories that are the subject of the technical 
corrections that are being finalized in this action are described in 
the Federal Register document for the final RTR rule amendments (84 FR 
9590, March 15, 2019).

C. What changes did we propose for the source categories in our 
November 1, 2019, RTR proposal?

    On November 1, 2019, the EPA published a proposed rule in the 
Federal Register for the Surface Coating of ALDT NESHAP, the Surface 
Coatings of MMPP NESHAP, and the Surface Coating of PPP NESHAP, 40 CFR 
part 63, subpart IIII, 40 CFR 63, subpart MMMM, and 40 CFR 63, subpart 
PPPP, respectively, that took into consideration the RTR analyses.
    We proposed to find that after compliance with the current NESHAP 
(i.e., MACT standards) the risks to public health from each of the 
source categories are acceptable, and that for each source category 
additional emission controls are not necessary to provide an ample 
margin of safety. Based on our technology review, we did not identify 
any cost-effective developments in practices, processes, or control 
technologies for any of the three surface coating source categories. 
Accordingly, we proposed no changes to the existing emission control 
requirements in subparts IIII, MMMM, and PPPP pursuant to the RTR 
analyses.
    We proposed the following amendments to improve rule effectiveness, 
provide regulatory flexibility, and comply with a legal ruling:
     For each source category, a requirement for electronic 
submittal of notifications, semi-annual reports, and compliance reports 
(which include performance test reports);
     for each source category, revisions to the SSM provisions 
of each NESHAP in order to ensure that they are consistent with the 
Court decision in Sierra Club v. EPA, 551 F. 3d 1019 (D.C. Cir. 2008), 
which vacated two provisions that exempted source owners and operators 
from the requirement to comply with otherwise applicable CAA section 
112(d) emission standards during periods of SSM;
     for each source category, adding 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 then 
subtract methane emissions from measured total gaseous organic mass 
emissions as carbon;
     for each source category, removing references to paragraph 
(d)(4) of the Occupational Safety and Health Administration (OSHA) 
Hazard Communication standard (29 CFR 1910.1200), which dealt with 
OSHA-defined carcinogens, and replacing that reference with a list of 
HAP that must be regarded as potentially carcinogenic based on the EPA 
guidelines;
     for each source category, a requirement to perform 
performance testing and reestablish operating limits no less frequently 
than every 5 years for sources that are using add-on controls to 
demonstrate compliance; and
     for each source category, IBR of alternative test methods 
and references to updated alternative test methods.
    We also proposed several minor editorial and technical changes in 
each subpart, as well as technical corrections to three other recently 
promulgated RTRs for the following source categories: Surface Coating 
of Large Appliances NESHAP (40 CFR 63, subpart NNNN); Printing, 
Coating, and Dyeing of Fabrics and Other Textiles NESHAP (40 CFR 63, 
subpart OOOO); and Surface Coating of Metal Furniture NESHAP (40 CFR 
63, subpart RRRR).

III. What is included in these final rules?

    This action finalizes the EPA's proposed determinations pursuant to 
the RTR provisions of CAA sections 112(d)(6) and (f)(2) for the Surface 
Coating of ALDT source category, the Surface Coatings of MMPP source 
category, and the Surface Coating of PPP source category. This action 
also finalizes other proposed changes to each NESHAP as proposed, 
including the following for each source category:
     A requirement for electronic submittal of notifications, 
semi-annual reports, and compliance reports (which include performance 
test reports);
     revisions to the SSM provisions of each NESHAP;
     adding 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 then subtract methane 
emissions from measured total gaseous organic mass emissions as carbon;
     replacing a reference to OSHA's Hazard Communication 
standard (29 CFR 1910.1200(d)(4)) with a list of HAP that must be 
regarded as potentially carcinogenic based on the EPA guidelines;
     adding a requirement for sources to perform periodic 
control device testing if they are using add-on controls to demonstrate 
compliance; and
     IBR of alternative test methods and references to updated 
alternative test methods.
    We are finalizing, as proposed, several minor editorial and 
technical changes in each subpart, including technical corrections to 
the Surface Coating of Large Appliances NESHAP (40 CFR 63, subpart 
NNNN); Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP (40 CFR 63, subpart OOOO); and Surface Coating of Metal 
Furniture NESHAP (40 CFR 63, subpart RRRR).

A. What are the final rule amendments based on the risk reviews for 
these source categories?

    This section describes the final amendments to the Surface Coating 
of ALDT NESHAP (40 CFR part 63, subpart IIII); the Surface Coating of 
Miscellaneous Metal Parts NESHAP (40 CFR part 63, subpart MMMM); and 
the Surface Coating of PPP NESHAP (40 CFR part 63, subpart PPPP) being 
promulgated pursuant to CAA section 112(f)(2). The EPA proposed no 
changes to these three subparts based on the risk reviews conducted 
pursuant to CAA section 112(f)(2). In this action, we are finalizing 
our proposed determination that, considering compliance with MACT, the 
public health risks from these three subparts are acceptable, and that 
the standards provide an ample margin of safety to protect public 
health and prevent an adverse environmental effect. The EPA received no 
new data or other information during the public comment period that 
causes us to change that proposed determination. Therefore, we are not 
requiring additional emission controls under CAA section 112(f)(2) for 
any of the three subparts in this action.

B. What are the final rule amendments based on the technology reviews 
for these source categories?

    We determined that there are no cost-effective developments in 
practices, processes, and control technologies that warrant revisions 
to the MACT standards for the Surface Coating of ALDT, Surface Coating 
of MMPP, and Surface Coating of PPP source categories. Therefore, we 
are not finalizing revisions to the MACT standards under CAA section 
112(d)(6) for any of the three subparts in this action.

[[Page 41107]]

C. What are the final rule amendments addressing emissions during 
periods of SSM?

    We are finalizing the proposed amendments to the Surface Coating of 
ALDT NESHAP; the Surface Coating of MMPP NESHAP; and the Surface 
Coating of PPP NESHAP to remove and revise provisions related to SSM. 
In its 2008 decision in Sierra Club v. EPA 551 F. 3d 1019 (D.C. Cir. 
2008), the Court vacated portions of two provisions in the EPA's CAA 
section 112 regulations governing the emissions of HAP during periods 
of SSM. Specifically, the Court vacated the SSM exemption contained in 
40 CFR 63.6(f)(1) and 40 CFR 63.6(h)(1), holding that under section 
302(k) of the CAA, emissions standards or limitations must be 
continuous in nature and that the SSM exemption violates the CAA's 
requirement that some CAA section 112 standards apply continuously.
    As detailed in section IV.A, B, and C of the November 1, 2019, 
proposal preamble, the ALDT NESHAP, MMPP NESHAP, and PPP NESHAP require 
that the standards apply at all times (see 40 CFR 63.3093(b), 
63.3900(a)(2), and 63.4492(b), respectively), consistent with the Court 
decision in Sierra Club v. EPA, 551 F. 3d 1019 (D.C. Cir. 2008). Table 
2 to Subpart IIII of Part 63, Table 2 to Subpart MMMM of Part 63, and 
Table 2 to Subpart PPPP of Part 63 (General Provisions applicability 
tables) are being revised to change the specification of the 
requirements that apply during periods of SSM. We are eliminating or 
revising certain recordkeeping and reporting requirements related to 
the eliminated SSM exemption. The EPA is also making other harmonizing 
changes to remove or modify inappropriate, unnecessary, or redundant 
language in the absence of the SSM exemption. We have determined that 
facilities in these source categories can meet the applicable emission 
standards in the Surface Coating of ALDT NESHAP, the Surface Coating of 
MMPP NESHAP, and the Surface Coating of PPP NESHAP at all times, 
including periods of startup and shutdown. Therefore, the EPA has 
determined that no additional standards are needed to address emissions 
during these periods. The legal rationale and detailed changes for SSM 
periods that we are finalizing here are set forth in the November 1, 
2019, preamble to the proposed rule. See 84 FR 58959 through 58963 for 
ALDT, 58971 through 58973 for MMPP, and 58980 through 58982 for PPP.
    Further, the EPA is not finalizing standards for malfunctions. As 
discussed in section IV.A, B, and C of the November 1, 2019, proposal 
preamble, the EPA interprets CAA section 112 as not requiring emissions 
that occur during periods of malfunction to be factored into 
development of CAA section 112 standards, although the EPA has the 
discretion to set standards for malfunctions where feasible. For these 
source categories, it is unlikely that a malfunction would result in a 
violation of the standards, and no comments were submitted that would 
suggest otherwise. Refer to section IV.A, B, and C of the November 1, 
2019, proposal preamble for further discussion of the EPA's rationale 
for the decision not to set standards for malfunctions, as well as a 
discussion of the actions a facility could take in the unlikely event 
that a facility fails to comply with the applicable CAA section 112 
standards as a result of a malfunction event, given that administrative 
and judicial procedures for addressing exceedances of the standards 
fully recognize that violations may occur despite good faith efforts to 
comply and can accommodate those situations.
    We are finalizing revisions to the General Provisions tables to 40 
CRF part 63, subparts IIII, MMMM, and PPPP, to eliminate requirements 
that include rule language providing an exemption for periods of SSM. 
Additionally, we are finalizing our proposal to eliminate language 
related to SSM that treats periods of startup and shutdown the same as 
periods of malfunction. Finally, we are finalizing our proposal to 
revise the Deviation Notification Report and related records as they 
relate to malfunctions. As discussed in detail in the proposal 
preamble, these revisions are consistent with the requirements in 40 
CFR 63.3093(b), 63.3900(a)(2), and 63.4492(b) stating that the 
standards apply at all times.
    We are finalizing a revision to the performance testing 
requirements at 40 CFR 63.3164(a)(1), 40 CFR 63.3964(a)(1), and 40 CFR 
63.4564(a)(1). The final performance testing provisions prohibit 
performance testing during SSM as these conditions are not 
representative of steady state operating conditions. The final rules 
also require that operators maintain records to document that operating 
conditions during the tests represent steady state conditions.

D. What other changes have been made to these NESHAP?

    These rules also finalize, as proposed, revisions to several other 
NESHAP requirements. We describe the revisions that apply to all the 
affected source categories in the following paragraphs.
    To increase the ease and efficiency of data submittal and data 
accessibility, we are finalizing a requirement that owners or operators 
of facilities in the Surface Coating of ALDT; Surface Coating of MMPP; 
and Surface Coating of PPP source categories submit electronic copies 
of certain required performance test reports through the EPA's Central 
Data Exchange (CDX) website using an electronic performance test report 
tool called the Electronic Reporting Tool (ERT). We also are 
finalizing, as proposed, provisions that allow facility operators the 
ability to seek extensions for submitting electronic reports for 
circumstances beyond the control of the facility, i.e., for a possible 
outage in the CDX or Compliance and Emissions Data Reporting Interface 
(CEDRI) or for a force majeure event in the time just prior to a 
report's due date, as well as the process to assert such a claim.
    For each subpart, we also are changing the format of references to 
test methods in 40 CFR part 60, appendix A to indicate where, in the 
eight sections of appendix A, each method is found.
    We are finalizing amendments to 40 CFR 63.3166(b), 40 CFR 
63.3966(b), and 40 CFR 63.4566(b) to add 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 then 
subtract methane emissions from measured total gaseous organic mass 
emissions as carbon, when facilities are using EPA Method 25A to 
measure control device destruction efficiency.
    For each subpart, we are finalizing the proposal to re-designate 
the list of organic HAP that must be used when a facility chooses to 
use the compliant material option (i.e., for calculating total organic 
HAP content of a coating material present at 0.1 percent or greater by 
mass). To specify the applicable HAP, we are changing the rules to 
remove the references to paragraph (d)(4) of OSHA's Hazard 
Communication standard (29 CFR 1910.1200) and replace it with a new 
table in each subpart (Table 5 to 40 CFR part 63, subpart IIII; Table 5 
to 40 CFR part 63, subpart MMMM; and Table 5 to 40 CFR part 63, subpart 
PPPP) that lists the applicable HAP. The organic HAP in these new 
tables are those HAP that were categorized in the EPA's Prioritized 
Chronic Dose-Response Values for Screening Risk Assessments (dated May 
9, 2014) as a ``human carcinogen,'' ``probable human carcinogen,'' or 
``possible human carcinogen'' according to The Risk Assessment 
Guidelines of 1986 (EPA/

[[Page 41108]]

600/8-87/045, August 1987) \2\ or as ``carcinogenic to humans,'' 
``likely to be carcinogenic to humans,'' or with ``suggestive evidence 
of carcinogenic potential'' according to the Guidelines for Carcinogen 
Risk Assessment (EPA/630/P-03/001F, March 2005).

    \2\ See https://www.epa.gov/fera/dose-response-assessment-assessing-health-risks-associated-exposure-hazardous-air-pollutants.
---------------------------------------------------------------------------

    We are including in the final rule for each subpart a requirement 
for facilities to conduct control device performance testing no less 
frequently than once every 5 years when using the emission rate with 
add-on controls compliance option. For facilities with title V permits 
that require comparable periodic testing prior to permit renewal, no 
additional testing is required, and we included provisions in the rule 
to allow facilities to harmonize the NESHAP testing schedule with a 
facility's current title V testing schedule.
1. Technical Amendments to the Surface Coating of ALDT NESHAP
    We are revising the monitoring provisions for thermal and catalytic 
oxidizers, as proposed, to clarify that a thermocouple is part of the 
temperature sensor referred to in 40 CFR 63.3168(c)(3) for purposes of 
performing periodic calibration and verification checks.
    We are adding, as proposed, a new paragraph 40 CFR 63.3130(p) and 
revising 40 CFR 63.3131(a) to allow that any records required to be 
maintained by 40 CFR part 63, subpart IIII that are submitted 
electronically via the EPA's CEDRI may be maintained in electronic 
format. We are also adding clarification that 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.
    We are amending 40 CFR 63.3166(b) to add the option of conducting 
EPA Method 18 of appendix A-6 to 40 CFR part 60, ``Measurement of 
Gaseous Organic Compound Emissions by Gas Chromatography,'' to measure 
and subtract methane emissions from total gaseous organic mass 
emissions as carbon when facilities are using EPA Method 25A.
    In the final rule, as proposed, we are adding and updating test 
methods that are incorporated by reference. In accordance with 
requirements of 1 CFR 51.5, the EPA is incorporating by reference the 
voluntary consensus standards (VCS) and other methods described in the 
amendments to 40 CFR 63.14:
     ASTM D1475-13, Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products, IBR approved for 40 CFR 
63.3151(b);
     ASTM D2369-10 (Reapproved 2015)\e\, Standard Test Method 
for Volatile Content of Coatings, IBR approved for 40 CFR 
63.3151(a)(2);
     ASTM D2697-03 (Reapproved 2014), Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings, IBR approved 
for 40 CFR 63.3161(f)(1);
     ASTM D5066-91 (Reapproved 2017), Standard Test Method for 
Determination of the Transfer Efficiency Under Production Conditions 
for Spray Application of Automotive Paints-Weight Basis, IBR approved 
for 40 CFR 63.3161(g);
     ASTM D5965-02 (Reapproved 2013), Standard Test Methods for 
Specific Gravity of Coating Powders, IBR approved for 40 CFR 
63.3151(b);

Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using 
Helium Gas Pycnometer, IBR approved for 40 CFR 63.3161(f)(1);
     ASTM D6266-00a (Reapproved 2017), Standard Test Method for 
Determining the Amount of Volatile Organic Compound (VOC) Released from 
Waterborne Automotive Coatings and Available for Removal in a VOC 
Control Device (Abatement), IBR approved for 40 CFR 63.3165(e); and
     EPA-450/3-88-018, Protocol for Determining the Daily 
Volatile Organic Compound Emission Rate of Automobile and Light-Duty 
Truck Topcoat Operations, IBR approved for 40 CFR 63.3130(c), 
63.3161(d) and (g), 63.3165(e), and appendix A to subpart IIII of part 
63.
2. Technical Amendments to the Surface Coating of MMPP NESHAP
    We are amending 40 CFR 63.3966(b) to add 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 then 
subtract methane emissions from total gaseous organic mass emissions as 
carbon when facilities are using EPA Method 25A.
    Current 40 CFR 63.3931 specifies how records must be maintained. We 
are adding clarification to this provision at 40 CFR 63.3931(a) that 
specifies the allowance to retain electronic records applies to all 
records that were submitted as reports electronically via the EPA's 
CEDRI. We are also adding text to the same provision clarifying that 
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.
    In the final rule, as proposed, we are adding and updating test 
methods that are incorporated by reference. In accordance with 
requirements of 1 CFR 51.5, the EPA is incorporating by reference the 
VCS and other methods described in the amendments to 40 CFR 63.14:
     ASTM D1475-13, Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products, IBR approved for 40 CFR 
63.3941(b)(4) and (c) and 63.3951(c);
     ASTM D2111-10 (Reapproved 2015), Standard Test Methods for 
Specific Gravity and Density of Halogenated Organic Solvents and Their 
Admixtures, IBR approved for 40 CFR 63.3951(c);
     ASTM Method D2369-10 (Reapproved 2015)\e\, Standard Test 
Method for Volatile Content of Coatings, IBR approved for 40 CFR 
63.3961(j)(3);
     ASTM D2697-03 (Reapproved 2014), Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings, IBR approved 
for 40 CFR 63.3941(b)(1);
     ASTM Method D5965-02 (Reapproved 2013), Standard Test 
Methods for Specific Gravity of Coating Powders, IBR approved for 40 
CFR 3951(c); and
     ASTM D6093-97 (Reapproved 2016), Standard Test Method for 
Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using 
Helium Gas Pycnometer, IBR approved for 40 CFR 63.3941(b)(1).
3. Technical Amendments to the Surface Coating of PPP NESHAP
    We are amending 40 CFR 63.4566(b)(4) to add 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 then subtract methane emissions from total gaseous organic 
mass emissions as carbon when facilities are using EPA Method 25A.
    Current 40 CFR 63.4530 specifies records that must be maintained. 
We are adding clarification to this provision at 40 CFR 63.4530(a) that 
specifies the allowance to retain electronic records applies to all 
records that were submitted as reports electronically via the EPA's 
CEDRI. We are also adding text to the same provision clarifying that 
this ability to maintain electronic copies does not affect the 
requirement for facilities to make records, data, and

[[Page 41109]]

reports available upon request to a delegated air agency or the EPA as 
part of an on-site compliance evaluation.
    We are clarifying and harmonizing the general requirement in 40 CFR 
63.4500(b) with the reporting requirement in 40 CFR 63.4520(a)(5), (6), 
and (7), and the recordkeeping requirement in 40 CFR 63.4530(h)(4).
    In the final rule, as proposed, we are adding and updating test 
methods that are incorporated by reference. In accordance with 
requirements of 1 CFR 51.5, the EPA is incorporating by reference the 
following VCS described in the amendments to 40 CFR 63.14:
     ASTM D1475-13, Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products, IBR approved for 40 CFR 
63.4551(c);
     ASTM D2111-10 (Reapproved 2015), Standard Test Methods for 
Specific Gravity and Density of Halogenated Organic Solvents and Their 
Admixtures, IBR approved for 40 CFR 63.4551(c); and
     ASTM D2369-10 (Reapproved 2015)\e\, Standard Test Method 
for Volatile Content of Coatings, IBR approved for 40 CFR 
63.4541(a)(2), and 63.4561(j)(3).
4. Technical Amendments to Other Subparts
    We are revising the NESHAP for Surface Coating of Large Appliances 
(40 CFR part 63, subpart NNNN); the NESHAP for Printing, Coating, and 
Dyeing of Fabrics and Other Textiles (40 CFR part 63, subpart OOOO); 
and the NESHAP for Surface Coating of Metal Furniture (40 CFR part 63, 
subpart RRRR) to make corrections after the three subparts were amended 
in a final rule published in the Federal Register on March 15, 2019 (84 
FR 9590). The proposed corrections were published on November 1, 2019 
(84 FR 58936), and no public comments on these corrections were 
received. Therefore, we are making the corrections to these three 
subparts as proposed.

E. What are the effective and compliance dates of the standards?

    The revisions to the MACT standards being promulgated in this 
action are effective on July 8, 2020.
    For affected sources in the ALDT, MMPP, and PPP source categories, 
the compliance date is January 5, 2021, with the exception of the 
electronic format for submitting semiannual compliance reports. For the 
electronic format for submitting semiannual compliance reports, both 
existing and new (or reconstructed) affected sources must comply within 
1 year after the electronic reporting templates are available on CEDRI, 
or 1 year after July 8, 2020, whichever is later. The EPA selected 
these compliance dates based on experience with similar industries and 
the EPA's detailed justification for the selected compliance dates is 
included in the preamble to the proposed rule (84 FR 58965, 58975, and 
58984).

F. What are the requirements for submission of performance test data to 
the EPA?

    As proposed, the EPA is taking a step to increase the ease and 
efficiency of data submittal and data accessibility. Specifically, the 
EPA is finalizing the requirement for owners or operators of facilities 
in the ALDT, MMPP, and PPP source categories to submit electronic 
copies of certain required performance test reports.
    Performance test results collected using test methods that are 
supported by the EPA's ERT as listed on the ERT website (https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test be submitted in the format generated 
through the use of the ERT. The ERT will generate an electronic report 
package which will be submitted to the CEDRI interface on the EPA's 
CDX. CEDRI can be accessed through the CDX website (https://cdx.epa.gov/).
    The requirement to submit performance test data electronically to 
the EPA does not create any additional performance testing and will 
apply only to those performance tests conducted using test methods that 
are supported by the ERT. A listing of the pollutants and test methods 
supported by the ERT is available at the ERT website. Electronic 
reporting will save time in the performance test submittal process. The 
electronic submittal of reports increases the usefulness of the data 
contained in those reports, is in keeping with current trends in data 
availability, further assists in the protection of public health and 
the environment, and ultimately results in less burden on regulated 
facilities. It also will improve compliance by facilitating the ability 
of regulated facilities to demonstrate compliance and the ability of 
air agencies and the EPA to assess and determine compliance. Electronic 
storage of reports make data more accessible for review, analysis, and 
sharing. Electronic reporting also eliminates paper-based, manual 
processes; thereby saving time and resources, simplifying data entry, 
eliminating redundancies, minimizing data reporting errors, and 
providing data quickly and accurately to affected facilities, air 
agencies, the EPA, and the public. For a more thorough discussion of 
electronic reporting of performance tests, see the memorandum, 
Electronic Reporting Requirements for New Source Performance Standards 
(NSPS) and National Emission Standards for Hazardous Air Pollutants 
(NESHAP) Rules, August 8, 2018, in the ALDT Docket, MMPP Docket, and 
PPP Docket.
    In summary, in addition to supporting regulation development, 
control strategy development, and other air pollution control 
activities, having an electronic database populated with performance 
test data will save industry, state/local/tribal agencies, and the EPA 
significant time, money, and effort while improving the quality of 
emission inventories and air quality regulations.

IV. What is the rationale for our final decisions and amendments for 
these source categories?

    For each amendment, this section provides a description of what we 
proposed and what we are finalizing for the amendment, the EPA's 
rationale for the final decisions and amendments, and a summary of key 
comments and responses. For all comments not discussed in this 
preamble, comment summaries and the EPA's responses can be found in the 
comment summary and response document available in the ALDT Docket, 
MMPP Docket, and PPP Docket.

A. Residual Risk Reviews

1. What did we propose pursuant to CAA section 112(f)?
a. Surface Coating of ALDT (40 CFR part 63, subpart IIII) Source 
Category
    Pursuant to CAA section 112(f)(2), the EPA conducted a residual 
risk review and presented the results of this review, along with our 
proposed decisions regarding risk acceptability and ample margin of 
safety, in the November 1, 2019, proposed rule for 40 CFR part 63, 
subpart IIII (84 FR 58954). The results of the risk assessment for the 
proposal are presented briefly below in Table 2 of this preamble. More 
detail is in the residual risk technical support document, Residual 
Risk Assessment for the Surface Coating of Automobiles and Light-Duty 
Trucks Source Category in Support of the 2019 Risk and Technology 
Review Proposed Rule, available in the ALDT Docket.

\1\ The TOSHI is the sum of the chronic noncancer hazard quotients (HQs) for substances that affect the same target organ or organ system.
\2\ The maximum estimated acute exposure concentration was divided by available short-term threshold values to develop HQ values (HQREL = HQ reference
  exposure level).

    The results of the proposal inhalation risk modeling using actual 
emissions data, as shown in Table 2 of this preamble, indicate that the 
maximum individual cancer risk based on actual emissions (lifetime) is 
10-in-1 million (driven by naphthalene and ethyl benzene from 
miscellaneous industrial processes--other/not classified), the maximum 
chronic noncancer TOSHI value based on actual emissions is 0.3 (driven 
by hexamethylene-1,6-diisocyanate from a painting topcoat process), and 
the maximum screening acute noncancer HQ value (off-facility site) 
could be up to 1 (driven by formaldehyde). At proposal, the total 
annual cancer incidence (national) from these facilities based on 
actual emission levels was estimated to be 0.01 excess cancer cases per 
year, or one case in every 100 years.
    The results of the proposal inhalation risk modeling using 
allowable emissions data, as shown in Table 2 of this preamble, 
indicate that the maximum individual cancer risk based on allowable 
emissions (lifetime) is 10-in-1 million (driven by naphthalene and 
ethyl benzene), and the maximum chronic noncancer TOSHI value based on 
allowable emissions is 0.3 (driven by hexamethylene-1,6-diisocyanate). 
At proposal, the total annual cancer incidence (national) from these 
facilities based on allowable emissions was estimated to be 0.01 excess 
cancer cases per year, or one case in every 100 years.
    The maximum individual cancer risk (lifetime) for the whole 
facility was determined to be 10-in-1 million at proposal (driven by 
naphthalene and ethyl benzene). The maximum facility-wide TOSHI for the 
source category was estimated to be 0.3 (driven by emissions of 
hexamethylene-1,6-diisocyanate). At proposal, the total estimated 
cancer incidence from the whole facility was determined to be 0.02 
excess cancer cases per year, or one excess case in every 50 years.
    One persistent and bioaccumulative HAP (PB-HAP) is emitted by 
facilities in the source category: Lead. In evaluating the potential 
for multipathway effects from emissions of lead, we compared modeled 
annual lead concentrations to the National Ambient Air Quality Standard 
(NAAQS) for lead of 0.15 milligrams per cubic meter (mg/m\3\), 
arithmetic mean concentration over a 3-month period. The highest annual 
average lead concentration of 1.5 x 10-5 mg/m\3\ is below 
the NAAQS level for lead, indicating a low potential for multipathway 
impacts of concern due to lead even assuming a shorter averaging period 
is analyzed. Based on this evaluation, we proposed that there is no 
significant potential for human health multi-pathway risks as a result 
of HAP emissions from this source category. Three environmental HAP are 
emitted by sources within this source category: Lead, hydrochloric acid 
(HCl) and hydrogen fluoride (HF). Therefore, at proposal, we conducted 
a screening-level evaluation of the potential adverse environmental 
risks associated with emissions of lead, HCl, and HF for the ALDT 
source category. Based on this evaluation, we proposed that we do not 
expect an adverse environmental effect as a result of HAP emissions 
from this source category.
    We weighed all health risk factors, including those shown in Table 
2 of this preamble, in our risk acceptability determination and 
proposed that the residual risks from the Surface Coating of ALDT 
source category are acceptable (section IV.A.2.a of proposal preamble, 
84 FR 58956, November 1, 2019).
    We then considered whether 40 CFR part 63, subpart IIII provides an 
ample margin of safety to protect public health. In considering whether 
the standards should be tightened to provide an ample margin of safety 
to protect public health, we considered the same risk factors that we 
considered for our acceptability determination and also considered the 
costs, technological feasibility, and other relevant factors related to 
emissions control options that might reduce risk associated with 
emissions from the source category. Related to risk, the baseline risks 
were low, and regardless of the availability of further control 
options, little risk reduction could be realized. As discussed further 
in section IV.B of this preamble, we did not identify any cost-
effective measures to further reduce HAP emissions for the Surface 
Coating of ALDT source category. Therefore, given the low baseline 
risks and lack of options for further risk reductions, we proposed that 
additional emission controls for this source category are not necessary 
to provide an ample margin of safety (section IV.A.2.b of proposal 
preamble, 84 FR 58956, November 1, 2019).
b. Surface Coating of MMPP (40 CFR part 63, subpart MMMM) Source 
Category
    Pursuant to CAA section 112(f)(2), the EPA conducted a residual 
risk review and presented the results of this review, along with our 
proposed decisions regarding risk acceptability and ample margin of 
safety, in the November 1, 2019, proposed rule for 40 CFR part 63, 
subpart MMMM (84 FR 58966). The results of the risk assessment for the 
proposal are presented briefly below in Table 3 of this preamble. More 
detail is in the residual risk technical support document, Residual 
Risk Assessment for the Surface Coating of MMPP Source Category in 
Support of the 2019 Risk and Technology Review Proposed Rule, available 
in the MMPP Docket.

\1\ The TOSHI is the sum of the chronic noncancer HQ for substances that affect the same target organ or organ system.
\2\ The maximum estimated acute exposure concentration was divided by available short-term threshold values to develop HQ values (HQREL = HQ reference

    The results of the proposal inhalation risk modeling using actual

maximum individual cancer risk based on actual emissions (lifetime) is 
20-in-1 million (driven by naphthalene and ethyl benzene from coating 
operations), the maximum chronic noncancer TOSHI value based on actual 
emissions is 0.8 (driven by antimony from coating operations), and the 
maximum screening acute noncancer HQ value (off-facility site) could be 
up to 4 (driven by glycol ethers). At proposal, the total annual cancer 
incidence (national) from these facilities based on actual emission 
levels was estimated to be 0.008 excess cancer cases per year, or one 
case in every 125 years.
    The results of the proposal inhalation risk modeling using 
allowable emissions data, as shown in Table 3 of this preamble, 
indicate that the maximum individual cancer risk based on allowable 
emissions (lifetime) is 30-in-1 million (driven by naphthalene and 
ethyl benzene), and the maximum chronic noncancer TOSHI value based on 
allowable emissions is 1 (driven by antimony). At proposal, the total 
annual cancer incidence (national) from these facilities based on 
allowable emissions was estimated to be 0.01 excess cancer cases per 
year, or one case in every 100 years.
    The maximum individual cancer risk (lifetime) for the whole 
facility was determined to be 100-in-1 million at proposal (driven by 
nickel from welding operations). The maximum facility-wide TOSHI for 
the source category was estimated to be 1 (driven by emissions of 
cobalt from a gel coating operation). At proposal, the total estimated 
cancer incidence from the whole facility was determined to be 0.04 
excess cancer cases per year, or one excess case in every 25 years.
    Three PB-HAP are emitted by facilities in the source category: 
Arsenic, cadmium, and lead. The PB-HAP emissions from these facilities 
did not exceed the Tier 1 multipathway screening value of 1 for cancer 
or noncancer. In evaluating the potential for multipathway effects from 
emissions of lead, we compared modeled annual lead concentrations to 
the NAAQS for lead of 0.15 mg/m\3\, arithmetic mean concentration over 
a 3-month period). The highest annual average lead concentration of 
0.059 mg/m\3\ is below the NAAQS level for lead, indicating a low 
potential for multipathway impacts of concern due to lead even assuming 
a shorter averaging period is analyzed. Based on this evaluation, we 
proposed that there is no significant potential for human health multi-
pathway risks as a result of HAP emissions from this source category. 
Four environmental HAP are emitted by facilities in this source 
category: Arsenic, cadmium, lead and HCl. Therefore, at proposal, we 
conducted a screening-level evaluation of the potential adverse 
environmental effects associated with emissions of arsenic, cadmium, 
lead, and HCl for the MMPP source category. Based on this evaluation, 
we proposed that we do not expect an adverse environmental effect as a 
result of HAP emissions from this source category.
    We weighed all health risk factors, including those shown in Table 
3 of this preamble, in our risk acceptability determination and 
proposed that the residual risks from the Surface Coating of MMPP 
source category are acceptable (section IV.B.2.a of proposal preamble, 
84 FR 58967, November 1, 2019).
    We then considered whether 40 CFR part 63, subpart MMMM provides an 
ample margin of safety to protect public health. In considering whether 
the standards should be tightened to provide an ample margin of safety 
to protect public health, we considered the same risk factors that we 
considered for our acceptability determination and also considered the 
costs, technological feasibility, and other relevant factors related to 
emissions control options that might reduce risk associated with 
emissions from the source category. Based on our review (described in 
section IV.B of this preamble), we identified and evaluated the use of 
add-on control technologies for the rubber-to-metal bonding and high-
performance coating subcategories.
    We determined that the added costs and cost effectiveness for these 
two coating subcategories ($9,500 per ton of HAP reduced for the 
rubber-to-metal bonding subcategory and $11,700 per ton for the high-
performance coating subcategory) are not justified. We proposed that 
these costs are unreasonable particularly because the risks are already 
low, and the risks would not be reduced in a meaningful manner by the 
control of these subcategories. Six facilities in the high-performance 
subcategory had a cancer risk above 1-in-1 million. The cancer risk for 
only one of these facilities would be reduced as a result of the add-on 
controls evaluated, going from 6-in-1 million to 2-in-1 million (based 
on actual emissions) because the facility would be required to reduce 
emissions. Only one facility in the rubber-to-metal bonding subcategory 
had a cancer risk above 1-in-1 million. The cancer risk for this 
facility would not be reduced as a result of the add-on controls 
evaluated because the facility is able to use averaging between the 
general-use subcategory and the rubber-to-metal bonding subcategory to 
meet the general-use emission limit and would not have to reduce 
emissions. Therefore, we proposed that additional emissions controls 
for this source category are not necessary to provide an ample margin 
of safety (section IV.B.2.b of proposal preamble, 84 FR 58968, November 
1, 2019). Of the 40 facilities in the high-performance subcategory, 
there were six with cancer risk above 1-in-1 million. The cancer risk 
for only one of these facilities would be reduced as a result of the 
add-on controls evaluated, going from 6-in-1 million to 2-in-1 million 
(based on actual emissions). Of the 16 facilities in the rubber-to-
metal bonding subcategory, only one had cancer risk

[[Page 41112]]

above 1-in-1 million. The cancer risk for this facility would not be 
reduced as a result of the add-on controls evaluated.
c. Surface Coating of PPP (40 CFR part 63, subpart PPPP) Source 
Category
    Pursuant to CAA section 112(f)(2), the EPA conducted a residual 
risk review and presented the results of this review, along with our 
proposed decisions regarding risk acceptability and ample margin of 
safety, in the November 1, 2019, proposed action for 40 CFR part 63, 
subpart PPPP (84 FR 58976). The results of the risk assessment for the 
proposal are presented briefly below in Table 4 of this preamble. More 
detail is in the residual risk technical support document, Residual 
Risk Assessment for the Surface Coating of PPP Source Category in 
Support of the 2019 Risk and Technology Review Proposed Rule, available 
in the PPP Docket.

\1\ The TOSHI is the sum of the chronic noncancer HQ for substances that affect the same target organ or organ system.
\2\ The maximum estimated acute exposure concentration was divided by available short-term threshold values to develop HQ values (HQREL = HQ reference
  exposure level).

    The results of the proposal inhalation risk modeling using actual 
emissions data, as shown in Table 4 of this preamble, indicate that the 
maximum individual cancer risk based on actual emissions (lifetime) is 
10-in-1 million (driven by formaldehyde, naphthalene, and ethyl benzene 
from coating operations), the maximum chronic noncancer TOSHI value 
based on actual emissions is 1 (driven by hexamethylene-1,6-
diisocyanate from coating operations), and the maximum screening acute 
noncancer HQ value (off-facility site) could be up to 4 (driven by 
glycol ethers). At proposal, the total annual cancer incidence 
(national) from these facilities based on actual emission levels was 
estimated to be 0.001 excess cancer cases per year, or one case in 
every 1,000 years.
    The results of the proposal inhalation risk modeling using 
allowable emissions data, as shown in Table 4 of this preamble, 
indicate that the maximum individual cancer risk based on allowable 
emissions (lifetime) is 10-in-1 million (driven by formaldehyde, 
naphthalene, and ethyl benzene), and the maximum chronic noncancer 
TOSHI value based on allowable emissions is 1 (driven by hexamethylene-
1,6-diisocyanate from coating operations). At proposal, the total 
annual cancer incidence (national) from these facilities based on 
allowable emissions was estimated to be 0.001 excess cancer cases per 
year, or one case in every 1,000 years.
    The maximum individual cancer risk (lifetime) for the whole 
facility was determined to be 70-in-1 million at proposal (driven by 
nickel and formaldehyde from a co-located boiler). The maximum 
facility-wide TOSHI for the source category was estimated to be 1 
(driven by emissions of nickel and formaldehyde from a co-located 
boiler). At proposal, the total estimated cancer incidence from the 
whole facility was determined to be 0.006 excess cancer cases per year, 
or one excess case in every 200 years.
    No PB-HAP are emitted by facilities in this source category; 
therefore, at proposal we did not estimate any human health multi-
pathway risks from this source category. No environmental HAP are 
emitted by facilities in this source category; therefore, we proposed 
that we do not expect an adverse environmental effect as a result of 
HAP emissions from this source category.
    We weighed all health risk factors, including those shown in Table 
4 of this preamble, in our risk acceptability determination and 
proposed that the residual risks from the Surface Coating of PPP source 
category are acceptable (section IV.C.2.a of proposal preamble, 84 FR 
58977, November 1, 2019).
    We then considered whether 40 CFR part 63, subpart PPPP provides an 
ample margin of safety to protect public health. In considering whether 
the standards should be tightened to provide an ample margin of safety 
to protect public health, we considered the same risk factors that we 
considered for our acceptability determination and also considered the 
costs, technological feasibility, and other relevant factors related to 
emissions control options that might reduce risk associated with 
emissions from the source category. Based on our review at proposal 
(described in section IV.B of this preamble), we did not identify any 
measures to further reduce HAP. Therefore, we proposed that additional 
emissions controls for this source category are not necessary to 
provide an ample margin of safety (section IV.C.2.b of proposal 
preamble, 84 FR 58978, November 1, 2019).
2. How did the risk reviews change since proposal?
    We have not changed any aspect of the risk assessments for any of 
the three source categories as a result of public comments received on 
the November 1, 2019, proposal for any of the three source categories.
3. What key comments did we receive on the risk reviews, and what are 
our responses?
    We received comments in support of and against the proposed 
residual risk reviews and our determinations that no revisions were 
warranted under CAA section 112(f)(2) for all three source categories. 
Generally, the comments that were not supportive of the determination 
from the risk reviews suggested changes to the underlying risk 
assessment methodology. For example, some commenters stated that the 
EPA should lower the acceptability benchmark so that risks below 100-
in-1 million are unacceptable, include emissions outside of the source 
categories in question in the risk assessment, and assume that 
pollutants with noncancer health risks have no safe level of exposure. 
After review of all the comments received, we determined that no 
changes to our Science Advisory Board-approved review process were 
necessary. The comments and our specific responses can be found in the 
document,

[[Page 41113]]

Summary of Public Comments and Responses for the Risk and Technology 
Reviews for Surface Coating Automobiles and Light-Duty Trucks, Surface 
Coating of Miscellaneous Metal Parts and Products, and Surface Coating 
of Plastic Parts and Products, available in the dockets for this action 
(Docket ID Nos. EPA-HQ-OAR-2019-0312, EPA-HQ-OAR-2019-0313, and EPA-HQ-
OAR-2019-0314).
4. What is the rationale for our final approach and final decisions for 
the risk reviews?
    As noted in our proposal, the EPA sets standards under CAA section 
112(f)(2) using ``a two-step standard-setting approach, with an 
analytical first step to determine an `acceptable risk' that considers 
all health information, including risk estimation uncertainty, and 
includes a presumptive limit on the maximum individual risk (MIR) of 
approximately 1-in-10 thousand'' (see 54 FR 38045, September 14, 1989). 
We weigh all health risk factors in our risk acceptability 
determination, including the cancer MIR, cancer incidence, the maximum 
cancer TOSHI, the maximum acute noncancer HQ, the extent of noncancer 
risks, the distribution of cancer and noncancer risks in the exposed 
population, and the risk estimation uncertainties.
    Since proposal, neither the quantitative risk assessment nor our 
determinations regarding risk acceptability, ample margin of safety, or 
adverse environmental effects have changed. For the reasons explained 
in the proposed rule and above, we find that the risks from the Surface 
Coating of ALDT, Surface Coating of MMPP, and Surface Coating of PPP 
source categories are acceptable, and the current standards provide an 
ample margin of safety to protect public health and prevent an adverse 
environmental effect. Therefore, we are not revising any of these three 
subparts to require additional controls pursuant to CAA section 
112(f)(2) based on the residual risk review, and we are maintaining the 
existing standards under CAA section 112(f)(2).

B. Technology Reviews

1. What did we propose pursuant to CAA section 112(d)(6)?
    Based on our review, we did not identify any developments in 
practices, processes, or control technologies for the Surface Coating 
of ALDT source category, and, therefore, we did not propose any changes 
to the standards under CAA section 112(d)(6). A brief summary of the 
EPA's findings in conducting the technology review of ALDT surface 
coating operations was included in the preamble to the proposed action 
(84 FR 58957, November 1, 2019). For a detailed discussion of the EPA's 
findings, refer to the memorandum, Technology Review for Surface 
Coating Operations in the Automobiles and Light-Duty Trucks Source 
Category, June 2019, in the ALDT Docket.
    In our technology review of the Surface Coating of MMPP source 
category, we identified and evaluated the use of add-on control 
technologies (e.g., regenerative thermal oxidizers) for two coating 
subcategories, high-performance coating and rubber-to-metal coating, 
that had not been previously considered during development of the MMPP 
NESHAP. This analysis is described in detail in the preamble to the 
proposed action (84 FR 58969, November 1, 2019). However, we determined 
that the added costs and cost effectiveness for these two coating 
subcategories ($9,500 per ton of HAP reduced for the rubber-to-metal 
coating subcategory and $11,700 per ton for the high-performance 
subcategory) were not justified. Aside from this, we did not identify 
any new or improved process equipment, work practices, or procedures 
that would further reduce emissions. Therefore, the EPA proposed no 
revisions to the MMPP NESHAP pursuant to CAA section 112(d)(6). For a 
detailed discussion of the EPA's findings, refer to the MMPP Technology 
Review Memo in the MMPP Docket.
    Based on our review, we did not identify any developments in 
practices, processes, or control technologies for the Surface Coating 
of PPP source category, and, therefore, we did not propose any changes 
to the standards under CAA section 112(d)(6). A brief summary of the 
EPA's findings in conducting the technology review of plastic parts 
surface coating operations was included in the preamble to the proposed 
action (84 FR 58978, November 1, 2019). For a detailed discussion of 
the EPA's findings, refer to the memorandum, Technology Review for the 
Plastic Parts and Products Surface Coating Operations Source Category, 
June 2019, in the PPP Docket.
2. How did the technology reviews change since proposal?
    We are making no changes to the conclusions of the technology 
review and are finalizing the results of the technology reviews for the 
Surface Coating of ALDT, Surface Coating of MMPP, and Surface Coating 
of PPP source categories as proposed.
3. What key comments did we receive on the technology reviews, and what 
are our responses?
    We received several general comments supporting the results of our 
technology reviews for all three source categories and one comment 
objecting to our conclusion that there have been no technology 
developments in these three source categories.
    Comment: One commenter alleged that the EPA has failed to meet the 
statutory obligation to conduct a technology review under CAA section 
112(d)(6). The commenter argued that the EPA has refused to complete 
the technology review by refusing to strengthen the emission standards 
for regulated pollutants based primarily on cost or cost effectiveness. 
The commenter argued that CAA section 112(d)(6) does not include that 
term ``cost effectiveness,'' and so the EPA's proposed action on the 
technology review is unlawful and arbitrary.
    Response: The EPA disagrees with the commenter that cost 
effectiveness cannot be considered in the technology reviews. CAA 
section 112(d)(6) does include the phrase ``as necessary'' and the EPA 
interprets ``as necessary'' to include a cost component, such as cost 
effectiveness. The EPA's interpretation that cost and cost 
effectiveness may be considered in technology reviews was affirmed by 
the Court in Association of Battery Recyclers, Inc. v. EPA, 716 F.3d 
667 (DC Cir. 2013).\3\ Therefore, the technology review for the Surface 
Coating of MMPP source category completed at proposal is not being 
revised based on this comment.
---------------------------------------------------------------------------

    \3\ See Association of Battery Recyclers, Inc. v. EPA, 716 F.3d 
667 (DC Cir. 2013), p. 673: Environmental petitioners next argue 
that the EPA impermissibly considered cost in revising emissions 
standards under CAA section 112(d)(6). But the statute only bars 
cost consideration in setting MACT floors under CAA section 
112(d)(3), see National Lime, 233 F.3d at 640; CAA section 112(d)(2) 
in contrast expressly directs the EPA to consider costs when setting 
beyond-the-floor standards, see 42 U.S.C. 7412(d)(2) (directing the 
Administrator to ``tak[e] into consideration the cost of achieving . 
. . emission reduction''). Petitioners are correct that CAA section 
112(d)(6) itself makes no reference to cost and that the Supreme 
Court has ``refused to find implicit in ambiguous sections of the 
[CAA] an authorization to consider costs that has elsewhere, and so 
often, been expressly granted.'' Whitman v. American Trucking 
Associations, Inc., 531 U.S. 457, 467, 121 S. Ct. 903, 149 L.Ed.2d 1 
(2001). But given that the EPA has no obligation to recalculate the 
MACT floor when revising standards, see supra at 672-73, and given 
that CAA section 112(d)(2) expressly authorizes cost consideration 
in other aspects of the standard-setting process, we believe this 
clear statement rule is satisfied.

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

[[Page 41114]]

4. What is the rationale for our final approach and final decisions for 
the technology reviews?
    For the reasons explained in the preamble to the proposed rules (84 
FR 58597, 58969, and 58978, November 1, 2019), and in our analysis of 
public comments explained above in section IV.B.3 of this preamble, we 
are making no changes to any of the three subparts to require 
additional controls pursuant to CAA section 112(d)(6) and are 
finalizing the results of the technology reviews as proposed.

C. Electronic Reporting Provisions

1. What did we propose?
    In the November 1, 2019, document, we proposed to require owners 
and operators of surface coating facilities in all three source 
categories to submit electronic copies of notifications, reports, and 
performance tests through the EPA's CDX, using the CEDRI. These include 
the initial notifications required in 40 CFR 63.9(b); notifications of 
compliance status required in 40 CFR 63.9(h); the performance test 
reports required in 40 CFR 63.7(g); and the semiannual reports required 
in 40 CFR 63.3120(a) for ALDT surface coating, 40 CFR 63.3920(a) for 
MMPP surface coating, and 40 CFR 63.4520(a) for PPP surface coating. A 
description of the electronic submission process is provided in the 
memorandum, Electronic Reporting Requirements for New Source 
Performance Standards (NSPS) and National Emission Standards for 
Hazardous Air Pollutants (NESHAP), August 8, 2018, in the ALDT, MMPP, 
and PPP Dockets. The proposed rule requirements would replace the 
current rule requirements to submit the notifications and reports to 
the Administrator at the appropriate address listed in 40 CFR 63.13. 
The proposed rule requirement would not affect submittals required by 
state air agencies.
2. What changed since proposal?
    We are finalizing the electronic reporting provisions as proposed 
with no changes (84 FR 58958, 58970, and 58979, November 1, 2019).
3. What key comments did we receive and what are our responses?
    Comment: Several commenters requested that additional opportunity 
should be provided for public review and comment of the electronic 
reporting templates before they are final and facilities are required 
to use them for electronic reporting. One commenter also requested that 
the EPA provide a notice and comment period through a Federal Register 
document for all future changes in reporting templates because many 
industry members do not track changes to the CEDRI website where the 
EPA intends to make future template changes. The commenter argued that 
this would be consistent with the requirements of both the CAA and the 
Administrative Procedures Act (APA) because, the commenter argues, the 
development of the reporting template constitutes a rulemaking action.
    Response: The EPA disagrees that changes to the electronic 
reporting template constitute a rulemaking because the reporting 
template does not create new requirements, but instead, provides the 
mechanism by which the sources report the information required to be 
submitted pursuant to the underlying NESHAP.
    The EPA promulgated the original MACT emissions standards and 
attendant monitoring, recordkeeping, and reporting requirements through 
notice and comment rulemaking, but the sources were not required to 
submit reports via electronic reporting at the time. The EPA is moving 
toward electronic reporting for all NESHAP and proposed to require 
electronic reporting for these source categories along with the RTR 
rulemaking. The electronic reporting template is the tool by which the 
sources will enter their required reports and data to CEDRI to comply 
with the NESHAP, but it does not establish, in itself, any 
requirements, including monitoring, recordkeeping, and reporting 
requirements. Any future revisions to the underlying NESHAP's 
monitoring, recordkeeping, and reporting requirements will be made 
through a proposed rulemaking that will be published in the Federal 
Register; thereby giving the public notice and an opportunity to 
comment. The changes to reporting templates, by contrast, are merely 
changes that are necessary to allow owners/operators to successfully 
submit reports (e.g., resolving issues with template cells that are not 
properly formatted, unlocking inadvertently locked cells, and 
correcting regulatory citations). The EPA disagrees that the APA and 
the CAA require such changes undergo notice and comment rulemaking in 
the Federal Register.
    We also note that if the reporting templates for these subparts are 
completed concurrently with the final rule publication, facilities will 
have 1 year after the final rule is published to submit semiannual 
compliance reports using the electronic reporting template in CEDRI. If 
the reporting templates are not finalized concurrently with the final 
rule publication, facilities will be required to submit semiannual 
compliance reports using the electronic reporting template in CEDRI 
once the reporting template has been available on the CEDRI website for 
one year. The dates that templates are initially made available in 
CEDRI are listed on the CEDRI website.
4. What is the rationale for our final approach for the electronic 
reporting provisions?
    For the reasons explained in the preamble to the proposed rules (84 
FR 58958, 58970, and 58979, November 1, 2019), and in the comment 
responses above in section IV.C.3 of this preamble, we are finalizing 
the electronic reporting provisions for 40 CFR parts 63, subparts IIII, 
MMMM, and PPPP, as proposed.

D. SSM Provisions

1. What did we propose?
    In the November 1, 2019, action, we proposed amendments to the ALDT 
NESHAP, the MMPP NESHAP, and the PPP NESHAP to remove and revise 
provisions related to SSM that are not consistent with the statutory 
requirement that the standards apply at all times. More information 
concerning the elimination of SSM provisions is in the preamble to the 
proposed rules (84 FR 58959, 58971, and 58980, November 1, 2019).
2. What changed since proposal?
    We are finalizing the SSM provisions as proposed except for some 
changes to the General Provisions references in Table 2 of 40 CFR part 
63, subpart IIII (84 FR 58959, 58971, and 58980, November 1, 2019).
3. What key comments did we receive and what are our responses?
    Comment: One commenter argued that the proposed removal and 
revision of the SSM provisions would effectively eliminate a 
longstanding provision applicable to magnet wire coating operations 
that allows for extra HAP emissions during SSM events, so long as the 
permittee addresses those events according to its facility SSM plan. 
The commenter acknowledged that the EPA is compelled to take this 
action by the decision in Sierra Club v. EPA, 551 F.3d 1019 (DC Cir. 
2008), but the commenter reported that certain facilities now are 
challenged to find a methodology for emission calculations during SSM 
periods.
    The commenter reported that magnet wire coaters--unless advised of 
an alternative approach--would account for SSM events in emission 
calculations by weighing coating hours in full compliance (with control 
percentage

[[Page 41115]]

determined through stack testing) v. coating hours during start-up, 
shutdown, and malfunction periods, where the default assumption during 
the latter is zero control. The commenter stated that the weighted 
efficiency ratio would then be applied to the total mass of HAP input 
to surface coating operations to determine estimated emissions.
    Response: The EPA agrees we are compelled to remove and revise the 
SSM provisions from each subpart consistent with Sierra Club v. EPA, 
551 F.3d 1019 (DC Cir. 2008).
    The commenter has not provided enough detail for the EPA to 
determine whether the compliance approach described by the commenter is 
consistent with the current requirements of 40 CFR part 63, subpart 
MMMM. However, subpart MMMM already includes provisions to account for 
deviation periods, so the commenter's proposed approach should not be 
necessary. For example, for coating operations that use an add-on 
control device, Equation 1 of 40 CFR 63.3961 includes the term 
HUNC, which is the total mass in kilograms of organic HAP in 
the coatings, thinners, and/or other additives, and cleaning materials 
used during all deviations specified in 40 CFR 63.3963(c) and (d) that 
occurred during the month, as calculated in Equation 1D of 40 CFR 
63.3961. The rest of subpart MMMM treats these HAP as being 
uncontrolled, which is consistent with the commenter's assumption of 
zero control during SSM events.
    Comment: One commenter recommended several changes to Table 2 
(Applicability of General Provisions) to 40 CFR part 63, subpart IIII, 
as result of the changes made to reflect the SSM changes:
     Clarify that the provisions of 40 CFR 63.6(e)(3), 
63.6(f)(1), 63.10(b)(2), and 63.10(d)(5) apply only to capture systems 
and add-on control devices used to comply with the standards, as in the 
current rule;
     correct an apparent drafting error and add back in a 
reference to 40 CFR 63.6(i)(16) with an indicator that it is still 
applicable to 40 CFR part 63, subpart IIII;
     do not finalize the applicability of 40 CFR 63.8(c)(7) 
from ``No'' to ``Yes'' unless the EPA provides further explanation of 
this change because it was not discussed in the preamble to the 
proposed rule; and
     combine the provisions of 40 CFR 63.9(h)(5) and (6) with 
the other notification of compliance status requirements in 40 CFR 
63.9(h)(1) through (3).
    Response: We agree with the commenter that the language indicating 
that the provisions of 40 CFR 63.6(e)(3), 63.6(f)(1), 63.10(b)(2), and 
63.10(d)(5) apply only to capture systems and add-on control devices 
used to comply with the standards is a useful clarification and it is 
being added back into the appropriate rows of Table 2 to 40 CFR part 
63, subpart IIII suggested by the commenter.
    The commenter is correct that 40 CFR 63.6(i)(16) is still 
applicable to 40 CFR part 63, subpart IIII and this has been added back 
into the final Table 2 to subpart IIII.
    We proposed to change the applicability of 40 CFR 63.8(c)(7) in 
Table 2 to 40 CFR part 63, subpart IIII from ``No'' to ``Yes'' because 
that was an apparent error in the original Table 2 to subpart IIII. 
Facilities are required to comply with 40 CFR 63.8(c)(7) as specified 
in 40 CFR 63.3120(a)(4), and the Table 2 to subpart IIII should already 
have been ``Yes'' instead of ``No.'' New references to 40 CFR 
63.8(c)(7) are also being added in 40 CFR 63.3120(a)(6)(vii) and 
(a)(8)(vi).
    We agree with the commenter that the provisions of 40 CFR 
63.9(h)(5) and (6) should be combined with the other notification of 
compliance status requirements in 40 CFR 63.9(h)(1) through (3). The 
provisions of 40 CFR 63.9(h)(5) and (6) were separated in drafting the 
revised table because 40 CFR 63.9(h)(4) is reserved, but we agree that 
keeping them together on one line as ``Sec.  63.9(h)(1) through (3), 
(5), and (6)'' would avoid confusion, so we are adopting that approach 
in the promulgated version of Table 2 to 40 CFR part 63, subpart IIII.
4. What is the rationale for our final approach for the SSM provisions?
    For the reasons explained in the proposed rule and after evaluation 
of the comments on the proposed amendments to the SSM provisions for 
the ALDT NESHAP, MMPP NESHAP, and PPP NESHAP, we are finalizing the 
proposed revisions related to SSM so that they are now consistent with 
the requirement that the standards apply at all times. More information 
concerning the proposed amendments to the SSM provisions is in the 
preamble to the proposed rules (84 FR 58959, 58971, and 58980, November 
1, 2019).

E. Ongoing Compliance Demonstrations

1. What did we propose?
    In the November 1, 2019, action, we proposed to require owners and 
operators of ALDT, MMPP, and PPP surface coating facilities that use 
the emission rate with add-on controls compliance option to conduct 
periodic performance testing of add-on control devices on a regular 
frequency of every 5 years to ensure the equipment continues to operate 
properly. This proposed periodic testing requirement included an 
exception to the general requirement for periodic testing for 
facilities using the catalytic oxidizer control options and following 
catalyst maintenance procedures that are found in 40 CFR part 63, 
subparts IIII, MMMM, and PPPP. These catalyst maintenance procedures 
include annual testing of the catalyst and other maintenance procedures 
that provide ongoing demonstrations that the control system is 
operating properly and may, thus, be considered comparable to 
conducting a performance test. The proposed periodic performance 
testing requirement also allows an exception from periodic testing for 
facilities using continuous emission monitoring systems (CEMS) to show 
actual emissions. The use of CEMS to demonstrate compliance would 
obviate the need for periodic testing.
    This proposed requirement did not require periodic testing or CEMS 
monitoring of facilities using the compliant materials option or the 
emission-rate without add-on controls compliance option because these 
two compliance options do not use any add-on controls or control 
efficiency measurements in the compliance calculations.
    The proposed periodic performance testing requirement requires 
facilities complying with the standards using emission capture systems 
and add-on controls and which are not already on a 5-year testing 
schedule to conduct the first of the periodic performance tests within 
3 years of the effective date of the revised standards. Afterward, they 
would conduct periodic testing before they renew their operating 
permits, but no longer than 5 years following the previous performance 
test. Additionally, facilities that have already tested as a condition 
of their permit within the last 2 years before the effective date would 
be permitted to maintain their current 5-year schedule.
2. What changed since proposal?
    We have revised the proposed periodic testing language in 40 CFR 
part 63, subparts IIII, MMMM, and PPPP, since proposal to clarify that 
testing is only required for add-on control devices and is not for 
emission capture systems. We are also revising 40 CFR 63.3093(a) to 
clarify that facilities in the ALDT source category are not required to 
meet any operating limits for any coating

[[Page 41116]]

operations that do not use add-on controls to comply with the emission 
limits in 40 CFR 63.3090 or 63.3091.
3. What key comments did we receive and what are our responses?
    Comment: One commenter recommended that proposed rule language at 
40 CFR 63.3163(c)(3) in subpart IIII should be revised to clarify that 
periodic performance testing is only required for the add-on control 
device and that capture system efficiency testing is not required. The 
commenter argued that the EPA provided no technical justification to 
require periodic capture efficiency testing, and that capture 
efficiency is not likely to change without structural or operational 
changes to the emission capture system.
    Response: The EPA agrees with the commenter and has revised the 
periodic performance testing language in 40 CFR part 63, subparts IIII, 
MMMM, and PPPP to clarify that the testing applies to the add-on 
control devices and does not include capture efficiency testing.
    Comment: One commenter requested that the final 40 CFR part 63, 
subpart IIII should clarify that timing of subsequent performance tests 
should be aligned with title V permit requirements for testing to avoid 
additional testing to comply with both the NESHAP and their title V 
permits. The commenter recommended that regulatory language should 
provide for periodic testing ``within the 5-year term of the Title V 
permit'' or ``within 5 years of the most recent testing,'' or something 
similar. The commenter stated that the EPA should not require testing 
within a specified time period from the issuance of the amended rule or 
by a specific date.
    Response: The EPA disagrees with the commenter that changes to the 
proposed rule language are needed because the proposed rule language 
already allows this flexibility. The proposed rule language at 40 CFR 
63.3163(c)(3) stated,

``. . . You must conduct the first periodic performance test before 
[date 3 years after date of publications of final rule in the 
Federal Register], 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 [date 2 years 
before date of publications of final rule in the Federal Register]. 
Thereafter you must conduct a performance test no later than 5 years 
following the previous performance test. . . .''

    Therefore, the proposed rule language already allows a facility to 
conduct a performance test within the 5-year period of a title V permit 
if testing is already required, and does not specify any additional 
testing, as long as the title V permit is renewed on a regular 5-year 
schedule as specified under 40 CFR part 70 and 40 CFR part 71.
    Comment: One commenter requested that the EPA should allow for 
performance testing extensions beyond the 5-year requirement when 
necessary to obtain representative conditions and when agreed to with 
the EPA or with an EPA-approved permitting authority. The commenter 
argued that if, for example, significant coating operation facility 
changes or product changes are planned near the end of a 5-year period, 
deferring testing until after the change occurs would be preferable to 
obtain a more representative result. The commenter noted that the 
General Provisions currently allow for delays in performance tests due 
to force majeure events or a waiver of subsequent performance tests 
under certain conditions, but the General Provisions do not 
specifically reference testing delays due to the need to establish 
representative conditions. The commenter provided two examples of 
permit language that allow for extensions of testing periods.
    Response: The EPA disagrees with the need to allow for testing 
delays and is not revising the proposed language to include the 
commenter's recommendation. The compliance calculations in 40 CFR part 
63, subparts IIII, MMMM, and PPPP require a facility to use the organic 
HAP destruction or removal efficiency (DRE) of the add-on control 
device. The standards already require that tests be performed under 
representative coating operation operating conditions and under 
representative emission capture system and add-on control device 
operating conditions, which specifically exclude testing during periods 
of startup, shutdown, nonoperation, and malfunction. The EPA currently 
does not have sufficient information to define the conditions under 
which an extension should be granted, and no additional information was 
provided by the commenter. The commenter also provided no additional 
information to indicate whether and how the situations described by the 
commenter (e.g., significant coating operation changes or product 
changes) would alter the DRE of an add-on control device.
    The EPA also notes that the purpose of periodic compliance testing 
is to not only demonstrate future compliance, but to also confirm past 
compliance. If a facility is planning significant changes that would 
prevent testing according to the 5-year schedule, the facility may need 
to complete testing earlier so as to demonstrate that the facility was 
in compliance under the original configuration. It may be necessary for 
the facility to repeat testing under the new configuration to re-
establish new operating limits and efficiency values for the emission 
capture and control system.
    Comment: One commenter requested that the EPA revise 40 CFR 
63.3093(a) to clarify that facilities in the ALDT source category that 
do not use add-on controls to comply with the emission limits in 40 CFR 
63.3090 or 63.3091 are not required to comply with the operating limits 
for add-on controls and emission capture systems. The commenters 
reported that the original language in 40 CFR 63.3093(a) only mentioned 
``coating operations without add-on controls'' and this has led to 
confusion because many facilities have add-on controls to limit VOC 
emissions, but they are not needed to comply with the HAP emission 
limits.
    Response: The EPA agrees that this change will avoid confusion and 
we will make the change to the language in 40 CFR part 63, subpart 
IIII. Other surface coating NESHAP, such as 40 CFR part 63, subparts 
MMMM and PPPP, already have language that avoids similar confusion over 
the applicability of the operating limits.
4. What is the rationale for our final approach for the ongoing 
compliance demonstrations?
    For the reasons explained in the preamble to the proposed rules (84 
FR 58963, 58974, and 58983, November 1, 2019), and in the comment 
responses above in section IV.E.3 of this preamble, we are finalizing 
the periodic testing provisions for 40 CFR part 63, subparts IIII, 
MMMM, and PPPP, as proposed. As also described in section IV.E.3 of 
this preamble, we are also making changes to each NESHAP to clarify 
that testing is only required for add-on control devices and is not 
required for emission capture systems. We are also revising 40 CFR 
63.3093(a) to clarify that facilities in the ALDT source category are 
not required to meet any operating limits for any coating operations 
that do not use add-on controls to comply with the emission limits in 
40 CFR 63.3090 or 63.3091, as described in section IV.E.3 of this 
preamble.

V. Summary of Cost, Environmental, and Economic Impacts and Additional 
Analyses Conducted

A. What are the affected facilities?

    Currently, we estimate 43 major source facilities are subject to 
the ALDT NESHAP and operating in the United

[[Page 41117]]

States. The affected source under the NESHAP is the collection of all 
coating operations; all storage containers and mixing vessels in which 
coatings, thinners, and cleaning materials are stored or mixed; all 
manual and automated equipment and containers used for conveying 
coatings, thinners, and cleaning materials; and all storage containers 
and all manual and automated equipment and containers used for 
conveying waste materials generated by a coating operation. A coating 
operation is defined as the equipment used to apply coating to a 
substrate (coating application) and to dry or cure the coating after 
application. A single coating operation always includes at least the 
point at which a coating is applied and all subsequent points in the 
affected source where organic HAP emissions from that coating occur. 
There may be multiple coating operations in an affected source. Coating 
application with hand-held nonrefillable aerosol containers, touchup 
bottles, touchup markers, marking pens, or pinstriping equipment is not 
a coating operation for the purposes of this subpart. The application 
of temporary materials such as protective oils and ``travel waxes'' 
that are designed to be removed from the vehicle before it is delivered 
to a retail purchaser is not a coating operation for the purposes of 40 
CFR part 61, subpart IIII.
    Currently, we estimate 368 major source facilities are subject to 
the MMPP NESHAP and operating in the United States. The affected source 
under the NESHAP is the collection of all coating operations; all 
storage containers and mixing vessels in which coatings, thinners, and 
cleaning materials are stored or mixed; all manual and automated 
equipment and containers used for conveying coatings, thinners, and 
cleaning materials; and all storage containers and all manual and 
automated equipment and containers used for conveying waste materials 
generated by a coating operation. A coating operation is defined as the 
equipment used to apply cleaning materials to a substrate to prepare it 
for coating application (surface preparation) or to remove dried 
coating; to apply coating to a substrate (coating application) and to 
dry or cure the coating after application; or to clean coating 
operation equipment (equipment cleaning). A single coating operation 
may include any combination of these types of equipment but always 
includes at least the point at which a given quantity of coating or 
cleaning material is applied to a given part and all subsequent points 
in the affected source where organic HAP are emitted from the specific 
quantity of coating or cleaning material on the specific part. There 
may be multiple coating operations in an affected source. Coating 
application with handheld, non-refillable aerosol containers, touch-up 
markers, or marking pens is not a coating operation for the purposes of 
40 CFR part 63, subpart MMMM.
    Currently, we estimate 125 major source facilities are subject to 
the PPP NESHAP and operating in the United States. The affected source 
under the NESHAP is the collection of coating operations; all storage 
containers and mixing vessels in which coatings, thinners, and cleaning 
materials are stored or mixed; all manual and automated equipment and 
containers used for conveying coatings, thinners, and cleaning 
materials; and all storage containers and all manual and automated 
equipment and containers used for conveying waste materials generated 
by a coating operation. A coating operation is defined as the equipment 
used to apply cleaning materials to a substrate to prepare it for 
coating application (surface preparation) or to remove dried coating; 
to apply coating to a substrate (coating application) and to dry or 
cure the coating after application; or to clean coating operation 
equipment (equipment cleaning). A single coating operation may include 
any combination of these types of equipment but always includes at 
least the point at which a given quantity of coating or cleaning 
material is applied to a given part and all subsequent points in the 
affected source where organic HAP are emitted from the specific 
quantity of coating or cleaning material on the specific part. There 
may be multiple coating operations in an affected source. Coating 
application with handheld, non-refillable aerosol containers, touch-up 
markers, or marking pens is not a coating operation for the purposes of 
40 CFR part 63, subpart PPPP.

B. What are the air quality impacts?

    At the current level of control, estimated emissions of volatile 
organic HAP from the 43 facilities in the ALDT source category are 
approximately 1,700 tpy. Current estimated emissions of volatile 
organic HAP from the 368 facilities in the MMPP source category are 
approximately 2,700 tpy. Current estimated emissions of volatile 
organic HAP from the 125 facilities in the PPP source category are 
approximately 760 tpy.
    The amendments require that all major sources in the ALDT, MMPP, 
and PPP source categories comply with the relevant emission standards 
at all times, including periods of SSM. We were unable to quantify the 
emissions that occur during periods of SSM or the specific emissions 
reductions that will occur as a result of this action. However, 
eliminating the SSM exemption has the potential to reduce emissions by 
requiring facilities to meet the applicable standard at all times and 
to minimize SSM periods.
    Indirect or secondary air emissions impacts are impacts that would 
result from, for example, the increased electricity, natural gas, or 
water usage associated with the operation of control devices (e.g., 
increased secondary emissions of criteria pollutants from power 
plants). Energy impacts consist of the electricity and steam needed to 
operate control devices and other equipment. The amendments would have 
no effect on the energy needs of the affected facilities in any of the 
three source categories and will, therefore, have no indirect or 
secondary air emissions impacts.

C. What are the cost impacts?

    We estimate that each affected facility in these three source 
categories will experience costs as a result of these final amendments 
for recordkeeping and reporting. Each facility will experience costs to 
read and understand the rule amendments. Costs associated with 
eliminating the SSM exemption were estimated as part of the reporting 
and recordkeeping costs and include time for re-evaluating previously 
developed SSM record systems. Costs associated with the requirement to 
electronically submit notifications and semi-annual compliance reports 
using CEDRI were estimated as part of the reporting and recordkeeping 
costs and include time for becoming familiar with CEDRI and the 
reporting template for semi-annual compliance reports. The 
recordkeeping and reporting costs are presented in section VI.C of this 
preamble.
    We are also finalizing a requirement for performance testing no 
less frequently than every 5 years for sources in each source category 
using the add-on controls compliance options. We estimate that five 
major source facilities subject to the ALDT NESHAP may incur costs to 
conduct periodic testing because they are currently using the emission 
rate with add-on controls compliance option, and the total cost for all 
five facilities subject to the ALDT NESHAP in a single year would be 
$95,000. Similarly, we estimate that seven major source facilities 
subject to the MMPP NESHAP may incur costs to conduct periodic testing 
because they

[[Page 41118]]

are currently using the emission rate with add-on controls compliance 
option, at a total cost in a single year of $133,000. Finally, we 
estimate that three major source facilities subject to the PPP NESHAP 
may incur costs to conduct periodic testing because they are currently 
using the emission rate with add-on controls compliance option, at a 
total cost in a single year of $57,000. These estimates exclude testing 
costs for facilities that have add-on controls and are currently 
required to perform periodic performance testing as a condition of 
their state operating permit. The cost for a facility to conduct a 
destruction or removal efficiency performance test using EPA Method 25 
or 25A is estimated to be about $19,000. For further information on the 
potential costs, see the memorandum titled Estimated Costs/Impacts 40 
CFR part 63 Subparts IIII, MMMM, and PPPP Monitoring Review Revisions, 
May 2019, in the ALDT Docket, MMPP Docket, and PPP Docket.

D. What are the economic impacts?

    The economic impact analysis is designed to inform decision makers 
about the potential economic consequences of the compliance costs 
outlined in section VI.C. of this preamble. To assess the maximum 
potential impact, the largest cost expected to be experienced in any 
one year is compared to the total sales for the ultimate owner of the 
affected facilities to estimate the total burden for each facility.
    For the final revisions to the ALDT NESHAP, the total cost is 
estimated to be approximately $113,000 for the 43 affected entities in 
the first year of the rule, and an additional $122,000 in testing and 
reporting costs for five facilities in the third year of the rule and 
every 5 years thereafter. The 43 affected facilities are owned by 14 
different parent companies, and the total costs associated with the 
final requirements range from 0.000002 to 0.0056 percent of annual 
sales revenue per ultimate owner. These costs are not expected to 
result in a significant market impact, regardless of whether they are 
passed on to the purchaser or absorbed by the firms.
    For the final revisions to the MMPP NESHAP, the total cost is 
estimated to be approximately $964,000 for the 368 affected entities in 
the first year of the rule, and an additional $172,000 in testing and 
reporting costs for seven facilities in the third year of the rule and 
every 5 years thereafter. The 368 affected facilities are owned by 265 
different parent companies, and the total costs associated with the 
final requirements range from 0.000002 to 0.25 percent of annual sales 
revenue per ultimate owner. These costs are not expected to result in a 
significant market impact, regardless of whether they are passed on to 
the purchaser or absorbed by the firms.
    For the final revisions to the PPP NESHAP, the total cost is 
estimated to be approximately $327,000 for the 125 affected entities in 
the first year of the rule, and an additional $74,000 in testing and 
reporting costs for three facilities in the third year of the rule and 
every 5 years thereafter. The 125 affected facilities are owned by 94 
different parent companies, and the total costs associated with the 
final requirements range from 0.000008 to 0.22 percent of annual sales 
revenue per ultimate owner. These costs are not expected to result in a 
significant market impact, regardless of whether they are passed on to 
the purchaser or absorbed by the firms.
    The EPA also prepared a small business screening assessment to 
determine whether any of the identified affected entities are small 
entities, as defined by the U.S. Small Business Administration. One of 
the facilities potentially affected by the final revisions to the ALDT 
NESHAP is a small entity. However, the annualized costs associated with 
the final requirements is 0.0056 percent of annual sales revenue for 
the owner of that facility. Of the facilities potentially affected by 
the final revisions to the MMPP NESHAP, 110 are small entities. 
However, the annualized costs associated with the final requirements 
for the 103 ultimate owners of these 110 affected small entities range 
from 0.001 to 0.25 percent of annual sales revenues per ultimate owner. 
Of the facilities potentially affected by the final revisions to the 
PPP NESHAP, 35 are small entities. However, the annualized costs 
associated with the final requirements for the 35 ultimate owners of 
these 35 affected small entities range from 0.0009 to 0.22 percent of 
annual sales revenues per ultimate owner. Therefore, there are no 
significant economic impacts on a substantial number of small entities 
from these final amendments.

E. What are the benefits?

    As stated in section V.B. of the November 1, 2019, RTR proposal (84 
FR 58986), we were unable to quantify the specific emissions reductions 
associated with eliminating the SSM exemption, although this change has 
the potential to reduce emissions of volatile organic HAP.
    Because these amendments are not considered economically 
significant, as defined by Executive Order 12866, we did not monetize 
the benefits of reducing these emissions. This does not mean that there 
are no benefits associated with the potential reduction in volatile 
organic HAP from this rule.

F. What analysis of environmental justice did we conduct?

    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes 
federal executive policy on environmental justice. The order directs 
federal agencies, to the greatest extent practicable and permitted by 
law, to make environmental justice part of their mission by identifying 
and addressing, as appropriate, disproportionately high and adverse 
human health or environmental effects of their programs, policies, and 
activities on minority populations and low-income populations in the 
United States.
    To examine the potential for any environmental justice issues that 
might be associated with these source categories, we performed a 
demographic analysis for each source category, which is an assessment 
of risks to individual demographic groups of the populations living 
within 5 kilometers (km) and within 50 km of the facilities. In the 
analysis, we evaluated the distribution of HAP-related cancer and 
noncancer risks from each source category across different demographic 
groups within the populations living near facilities.
1. Surface Coating of ALDT
    The results of the demographic analysis for the Surface Coating of 
ALDT source category are summarized in Table 5 of this preamble. These 
results, for various demographic groups, are based on the estimated 
risk from actual emissions levels for the population living within 50 
km of the facilities.
    The results of the ALDT source category demographic analysis 
indicate that emissions from the source category expose approximately 
15,000 people to a cancer risk at or above 1-in-1 million and no one is 
exposed to a chronic noncancer HI greater than 1. The overall percent 
of the population that is minorities is similar nationally (38 percent) 
and for the category population with cancer risk greater than or equal 
to 1-in-1 million (40 percent). However, the category population with 
cancer risk greater than or equal to 1-in-1 million has a greater 
percent Hispanic population (27 percent) as compared to the national 
percent Hispanic population (18 percent).

2. Surface Coating of MMPP
    The results of the demographic analysis for the Surface Coating of 
MMPP source category are summarized in Table 6 of this preamble. These 
results, for various demographic groups, are based on the estimated 
risk from actual emissions levels for the population living within 50 
km of the facilities.
    The results of the MMPP source category demographic analysis 
indicate that approximately 18,000 people are exposed to a cancer risk 
at or above 1-in-1 million and no one is exposed 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: ``White,'' ``Below the Poverty Level,'' and 
``Over 25 and Without a High School Diploma.''

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 this rule have been 
submitted for approval to OMB under the PRA, as discussed for each 
source category covered by this action in sections VI.C.1, 2, and 3 of 
this preamble.
1. Surface Coating of ALDT
    The Information Collection Request (ICR) document that the EPA 
prepared has been assigned EPA ICR number 2045.09. You can find a copy 
of the ICR in the ALDT Docket for this rule (Docket ID No. EPA-HQ-OAR-
2019-0314), and it is briefly summarized here. The information 
collection requirements are not enforceable until OMB approves them.
    As part of the RTR for the ALDT NESHAP, the EPA is not revising the 
emission limit requirements. 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, notifications, and reports. 
This information is being collected to assure compliance with 40 CFR 
part 63, subpart IIII. 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 surface 
coating of ALDT.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart IIII).
    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 
five facilities will be required to conduct performance testing in the 
3 years after the amendments are final.
    Frequency of response: The total number of responses in year 1 is 
129 and in year 3 is 15. Year 2 would have no responses.
    Total estimated burden: The average annual burden to the ALDT 
surface coating facilities over the 3 years after the amendments are 
finalized is estimated to be 410 hours (per year). Burden is defined at 
5 CFR 1320.3(b).
    Total estimated cost: The average annual cost to the ALDT surface 
coating facilities is $47,000 in labor costs in the first 3 years after 
the amendments are final. The average annual capital and operation and 
maintenance (O&M) costs is $32,000.
2. Surface Coating of MMPP
    The ICR document that the EPA prepared has been assigned EPA ICR 
number 2056.08. You can find a copy of the ICR in the MMPP Docket for 
this rule (Docket ID No. EPA-HQ-OAR-2019-0312), and it is briefly 
summarized here. The information collection requirements are not 
enforceable until OMB approves them.
    As part of the RTR for the MMPP NESHAP, the EPA is not revising the 
emission limit requirements. 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, notifications, and reports. 
This information is being collected to assure compliance with 40 CFR 
part 63, subpart MMMM. 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 surface 
coating of MMPP.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart MMMM).
    Estimated number of respondents: In the 3 years after the 
amendments are

[[Page 41122]]

final, approximately 368 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 
1,104 and in year 3 is 21. Year 2 would have no responses.
    Total estimated burden: The average annual burden to the MMPP 
surface coating facilities over the 3 years after the amendments are 
final is estimated to be 2,930 hours (per year). Burden is defined at 5 
CFR 1320.3(b).
    Total estimated cost: The average annual cost to the MMPP surface 
coating facilities is $334,000 in labor costs in the first 3 years 
after the amendments are final. The average annual capital and O&M cost 
is $44,000.
3. Surface Coating of PPP
    The ICR document that the EPA prepared has been assigned EPA ICR 
number 2044.09. You can find a copy of the ICR in the PPP Docket for 
this rule (Docket ID No. EPA-HQ-OAR-2019-0313), and it is briefly 
summarized here. The information collection requirements are not 
enforceable until OMB approves them.
    As part of the RTR for the PPP NESHAP, the EPA is not revising the 
emission limit requirements. 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, notifications, and reports. 
This information is being collected to assure compliance with 40 CFR 
part 63, subpart PPPP. 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 surface 
coating of PPP.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart PPPP).
    Estimated number of respondents: In the 3 years after the 
amendments are final, approximately 125 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 
375 and in year 3 is nine. Year 2 would have no responses.
    Total estimated burden: The average annual burden to the PPP 
surface coating facilities over the 3 years after the amendments are 
final is estimated to be 1,007 hours (per year). Burden is defined at 5 
CFR 1320.3(b).
    Total estimated cost: The average annual cost to the PPP surface 
coating facilities is $115,000 in labor costs in the first 3 years 
after the amendments are final. The average annual capital and O&M cost 
is $19,000.
    This action does not impose any new information collection burden 
related to the NESHAP for Surface Coating of Large Appliances; NESHAP 
for Printing, Coating, and Dyeing of Fabrics and Other Textiles; and 
NESHAP for Surface Coating of Metal Furniture. OMB has previously 
approved the information collection activities contained in the 
existing regulations and has assigned OMB control number 2060-0457 for 
NESHAP for Surface Coating of Large Appliances; 2060-0522 for NESHAP 
for Printing, Coating, and Dyeing of Fabrics and Other Textiles; and 
2060-0518 for NESHAP for Surface Coating of Metal Furniture. This 
notice only finalizes technical corrections to these standards and does 
not impact the reporting or recordkeeping requirements.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB 
approves the ICRs, the Agency will announce that approval in the 
Federal Register and publish a technical amendment to 40 CFR part 9 to 
display the OMB control number for the approved information collection 
activities contained in the final rule.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. The 
economic impact associated with the requirements in this action for the 
affected small entities is described in section V.D. of this preamble.

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 (ALDT 
surface coating, MMPP surface coating, and PPP surface coating). Thus, 
Executive Order 13175 does not apply to this action.

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

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe the environmental health or safety 
risks addressed by this action present a disproportionate risk to 
children. This action's health and risk assessments are contained in 
sections III.A and C, IV.A.1 and 2, IV.B.1 and 2, and IV.C.1 and 2 of 
this preamble and are further documented in the Residual Risk 
Assessment for the Surface Coating of ALDT Source Category in Support 
of the 2020 Risk and Technology Review Final Rule, Residual Risk 
Assessment for the Surface Coating of MMPP Source Category in Support 
of the 2020 Risk and Technology Review Final Rule, and Residual Risk 
Assessment for the Surface Coating of PPP Source Category in Support of 
the 2020 Risk and Technology Review Final Rule, in the ALDT Docket, 
MMPP Docket, and PPP Docket, respectively.

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

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

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

    This rulemaking involves technical standards. The EPA conducted 
searches for the MACT standards through the Enhanced National Standards 
Systems Network Database managed by the American National Standards 
Institute. We also contacted VCS organizations and accessed and 
searched their databases. During the EPA's VCS search, if the title or 
abstract (if provided) of the

[[Page 41123]]

VCS described technical sampling and analytical procedures that are 
similar to the EPA's reference method, the EPA reviewed it as a 
potential equivalent method. The EPA is finalizing, as proposed, 
addition of methods to the ALDT NESHAP, the MMPP NESHAP, and the PPP 
NESHAP, as discussed in this section VI.J.
    The EPA is amending the ALDT NESHAP, the MMPP NESHAP, and the PPP 
NESHAP to provide owners and operators with the option of using two new 
methods. We are adding 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. We are also 
amending each of these NESHAP to incorporate by reference ASTM D2369-10 
(Reapproved 2015)\e\, ``Standard Test Method for Volatile Content of 
Coatings,'' into these three NESHAP as an alternative to EPA Method 24 
for the determination of the volatile matter content in surface 
coatings. ASTM D2369-10 (Reapproved 2015)\e\ is a test method that 
allows for more accurate results for multi-component chemical resistant 
coatings.
    We are amending the MMPP NESHAP and the PPP NESHAP to incorporate 
by reference ASTM D2111-10 (Reapproved 2015), ``Standard Test Methods 
for Specific Gravity and Density of Halogenated Organic Solvents and 
Their Admixtures,'' as an alternative to ASTM D1475-13. ASTM D2111-10 
(Reapproved 2015) is a test method that allows measurement of specific 
gravity at different temperatures that are chosen by the analyst.
    We are amending all three NESHAP to update ASTM D1475-98 
(Reapproved 2003), ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products,'' by incorporating by reference 
ASTM D1475-13, ``Standard Test Method for Density of Liquid Coatings, 
Inks, and Related Products.'' This test method covers the measurement 
of the density of paints, inks, varnishes, lacquers, and components 
thereof, other than pigments, when in fluid form.
    We are amending the ALDT NESHAP and the MMPP NESHAP to update ASTM 
D2697-86 (Reapproved 1998), ``Standard Test Method for Volume 
Nonvolatile Matter in Clear or Pigmented Coatings,'' by incorporating 
by reference ASTM D2697-03 (Reapproved 2014), which is the updated 
version of the previously approved method, and to update ASTM D6093-97 
(Reapproved 2003), ``Standard Test Method for Percent Volume 
Nonvolatile Matter in Clear or Pigmented Coatings Using Helium Gas 
Pycnometer,'' by incorporating by reference ASTM D6093-97 (Reapproved 
2016), which is the updated version of the previously approved method. 
ASTM D2697-03 (Reapproved 2014) is a test method that can be used to 
determine the volume of nonvolatile matter in clear and pigmented 
coatings, and ASTM D6093-97 (Reapproved 2016) is a test method that can 
be used to determine the percent volume of nonvolatile matter in clear 
and pigmented coatings.
    We are amending the ALDT NESHAP to update ASTM D5066-91 (Reapproved 
2001), ``Standard Test Method for Determination of the Transfer 
Efficiency Under Production Conditions for Spray Application of 
Automotive Paints-Weight Basis,'' by incorporating by reference ASTM 
D5066-91 (Reapproved 2017), which is the updated version of the 
previously approved method. This test method covers procedures for 
determination of the transfer efficiency (using a weight method) under 
production conditions for in-plant spray application of automotive 
paints as outlined in Section 18 of EPA 450/3-88-018.
    We are amending the ALDT NESHAP and the MMPP NESHAP to update ASTM 
D5965-02, ``Standard Test Methods for Specific Gravity of Coating 
Powders,'' by incorporating by reference ASTM D5965-02 (Reapproved 
2013), which is the updated version of the previously approved method. 
These test methods cover three procedures for determining the specific 
gravity (see definition) of coating powders, i.e., Test Method A--For 
Testing Coating Powders, Excluding Metallics; Test Method B--For Tests 
Requiring Greater Precision than Test Method A, Including Metallics, 
Using Helium Pycnometry; and Test Method C--For Theoretical Calculation 
Based on Raw Material.
    We are amending the ALDT NESHAP to update ASTM D6266-00a, 
``Standard Test Method for Determining the Amount of Volatile Organic 
Compound (VOC) Released from Waterborne Automotive Coatings and 
Available for Removal in a VOC Control Device (Abatement),'' by 
incorporating by reference ASTM D6266-00a (Reapproved 2017), which is 
the updated version of the previously approved method. This test method 
describes the determination of the amount of VOC released from applied 
waterborne automotive coatings that is available for delivery to a VOC 
control device. The determination is accomplished by measuring the 
weight loss of a freshly coated test panel subject to evaporation or 
drying and by analysis of the VOC or water content in the coating.
    The ASTM standards are available from ASTM International 100 Barr 
Harbor Drive, Post Office Box C700, West Conshohocken, PA 19428-2959. 
See https://www.astm.org/.
    The EPA is amending the ALDT NESHAP to incorporate by reference 
EPA-450/3-88-018 ``Protocol for Determining the Daily Volatile Organic 
Compound Emission Rate of Automobile and Light-Duty Truck Topcoat 
Operations,'' for use in 40 CFR 63.3130(c), 63.3161(d), and (g), 
63.3165(e), and appendix A to subpart IIII of part 63. This protocol 
determines the daily VOC emission rate (pounds of VOC per gallon of 
coating solids deposited) for a complete ALDT topcoat operation and is 
available in the ALDT Docket. The protocol is designed for uses in 
cases where topcoat emission limit is stated in units of pounds of VOC 
per gallon of solids deposited, compliance is demonstrated each day, 
and entire topcoat operation is treated as a single entity. The 
protocol uses the number of square feet coated on each vehicle in each 
booth with each coating as the basis for the daily weighting of 
individual transfer efficiency and bake oven exhaust control values. 
The method is intended to apply to primary coatings for new ALDT 
bodies, body parts for new ALDT, and other parts that are coated along 
with these bodies or body parts. It can also be downloaded from the 
EPA's website at the National Service Center for Environmental 
Publications, just access the following website at https://nepis.epa.gov and search either the title or document number.
    The EPA decided not to include certain other VCS; these methods are 
impractical as alternatives because of the lack of equivalency, 
documentation, validation date, and other important technical and 
policy considerations. The search and review results have been 
documented and are in the memoranda titled Voluntary Consensus Standard 
Results for NESHAP RTR: Surface Coating of Automobile and Light-Duty 
Trucks, June 2019, Voluntary Consensus Standard Results for NESHAP RTR: 
Surface Coating of Miscellaneous Metal Parts, June 2019, and Voluntary 
Consensus Standard Results for NESHAP RTR: Surface Coating of Plastic 
Parts and Products, June 2019, in the ALDT Docket, MMPP Docket, and the 
PPP Docket, respectively.
    The revised regulatory text contains references to ANSI/ASME PTC 
19.10-

1981 (Sec.  63.3166) and ASTM D5087-02 (Sec.  63.3165 and appendix A to 
subpart IIII). Both of these standards were previously approved for 
these sections. 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). 
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 titled Risk and 
Technology Review--Analysis of Demographic Factors for Populations 
Living Near Automobile and Light-Duty truck Surface Coating Category 
Operations, March 2019, Risk and Technology Review--Analysis of 
Demographic Factors for Populations Living Near the Surface Coating of 
Miscellaneous Metal Parts and Products Source Category, May 2019, and 
Risk and Technology Review--Analysis of Demographic Factors for 
Populations Living Near Surface Coating of Plastic Parts and Products 
Source Category Operations, April 2019, available in the ALDT Docket, 
MMPP Docket, and the PPP Docket, respectively.

L. Congressional Review Act (CRA)

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

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.
* * * * *
    (f) Before January 5, 2021, if your affected source uses emission 
capture systems and add-on control devices, 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 startup, 
shutdown, and corrective actions in the event of a malfunction of the 
emission capture system or the add-on control devices. On and after 
January 5, 2021, the SSMP is not required.

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) Reporting during EPA system outages. If you are required to 
electronically submit a report through the 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 the 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 the EPA system outage 
and allow an extension to the reporting deadline is solely within the 
discretion of the Administrator.
    (h) Reporting during force majeure events. 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.

9. Section 63.3151 is amended by revising paragraphs (a)(1)(i), (a)(2) 
and (4), and (b) to read as follows.

Sec.  63.3151  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 
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 
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 (e.g., 0.3791).
* * * * *
    (2) EPA Method 24 (appendix A-7 to 40 CFR part 60). For coatings, 
you may use EPA Method 24 to determine the mass fraction of nonaqueous 
volatile matter and use that value as a substitute for mass fraction of 
organic HAP. As an alternative to using EPA Method 24, you may use ASTM 
D2369-10 (Reapproved 2015)\e\ (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 compounds. For 
example, if toluene (not listed in table 5 of this subpart) is 0.5 
percent of the material by mass, you do not have to count it. If there 
is a disagreement between such information and results of a test 
conducted according to paragraphs (a)(1) through (3) of this section, 
then the test method results will take precedence, unless after 
consultation, the facility demonstrates to the satisfaction of the 
enforcement authority that the facility's data are correct.
* * * * *
    (b) Determine the density of each material used. Determine the 
density of each material used during the compliance period from test 
results using ASTM D1475-13 (incorporated by reference, see Sec.  
63.14) or for powder coatings, test method A or test method B of ASTM 
D5965-02 (Reapproved 2013) (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 
or ASTM D5965-02 (Reapproved 2013), test method A or test method B test 
results and the supplier's or manufacturer's information, the test 
results will take precedence unless after consultation, the facility 
demonstrates to the satisfaction of the enforcement authority that the 
facility's data are correct.

12. Section 63.3163 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.  63.3163  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.  63.3093 that applies to you, as specified in 
table 1 to this subpart, and you must conduct 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.  63.3161(k) for 
controlled coating operations, you must conduct periodic performance 
tests of add-on controls and establish the operating limits required by 
Sec.  63.3093 within 5 years following the previous performance test. 
You must conduct the first periodic performance test before July 8, 
2023, 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 July 8, 2022. 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. For any control device for which you are 
using the catalytic oxidizer control option at Sec.  63.3167(b) and 
following the catalyst maintenance procedures in Sec.  63.3167(b)(6), 
you are not required to conduct periodic control device performance 
testing as specified by this paragraph. For any control device for 
which instruments are used to continuously measure organic compound 
emissions, you are not required to conduct periodic control device 
performance testing as specified by this paragraph. The requirements of 
this paragraph do not apply to measuring emission capture system 
efficiency.
* * * * *
    (f) If there were no deviations from the emission limitations, 
submit a statement as part of the semiannual compliance report that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec.  
63.3090(a) or Sec.  63.3091(a), Sec.  63.3090(b) or Sec.  63.3091(b), 
or Sec.  63.3092(a) or Sec.  63.3092(b), you achieved the operating 
limits required by Sec.  63.3093, and you achieved the work practice 
standards required by Sec.  63.3094 during each compliance period.
* * * * *
    (h) Before January 5, 2021, consistent with Sec. Sec.  63.6(e) and 
63.7(e)(1), deviations that occur during a period of SSM of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with Sec.  63.6(e)(1). The 
Administrator will determine whether deviations that occur during a 
period you identify as a SSM are violations according to the provisions 
in Sec.  63.6(e). On and after January 5, 2021, the provisions of this 
paragraph no longer apply.

13. Section 63.3164 is amended by revising paragraphs (a) introductory 
text and (a)(1) to read as follows:

Sec.  63.3164  What are the general requirements for performance tests?

    (a) You must conduct each applicable performance test required by 
Sec. Sec.  63.3160, 63.3163, and 63.3171 according to the requirements 
in Sec.  63.7(e)(1) 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. Before January 5, 2021, operations during 
periods of SSM, and during periods of nonoperation do not constitute 
representative conditions. You must record the process information that 
is necessary to document operating conditions during the test and 
explain why the conditions represent normal operation. On and after 
January 5, 2021, 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

[[Page 41131]]

necessary to determine the conditions of performance tests.

14. Section 63.3165 is amended by revising the introductory text and 
paragraphs (e) introductory text, the definition of 
``Wvocc,i'' in Equation 6 of paragraph (e)(2), the 
definition of ``Wvocc,i'' in Equation 7 of paragraph (e)(3), 
and the definition of ``Ws,i'' in Equation 8 of paragraph 
(e)(4) to read as follows:

Sec.  63.3165  How do I determine the emission capture system 
efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required 
by Sec. Sec.  63.3160 and 63.3163. For purposes of this subpart, a 
spray booth air seal is not considered a natural draft opening in a PTE 
or a temporary total enclosure provided you demonstrate that the 
direction of air movement across the interface between the spray booth 
air seal and the spray booth is into the spray booth. For purposes of 
this subpart, a bake oven air seal is not considered a natural draft 
opening in a PTE or a temporary total enclosure provided you 
demonstrate that the direction of air movement across the interface 
between the bake oven air seal and the bake oven is into the bake oven. 
You may use lightweight strips of fabric or paper, or smoke tubes to 
make such demonstrations as part of showing that your capture system is 
a PTE or conducting a capture efficiency test using a temporary total 
enclosure. You cannot count air flowing from a spray booth air seal 
into a spray booth as air flowing through a natural draft opening into 
a PTE or into a temporary total enclosure unless you elect to treat 
that spray booth air seal as a natural draft opening. You cannot count 
air flowing from a bake oven air seal into a bake oven as air flowing 
through a natural draft opening into a PTE or into a temporary total 
enclosure unless you elect to treat that bake oven air seal as a 
natural draft opening.
* * * * *
    (e) Panel testing to determine the capture efficiency of flash-off 
or bake oven emissions. You may conduct panel testing to determine the 
capture efficiency of flash-off or bake oven emissions using ASTM 
D5087-02 (incorporated by reference, see Sec.  63.14), ASTM D6266-00a 
(Reapproved 2017) (incorporated by reference, see Sec.  63.14), or the 
guidelines presented in ``Protocol for Determining the Daily Volatile 
Organic Compound Emission Rate of Automobile and Light-Duty Truck 
Topcoat Operations,'' EPA-450/3-88-018 (incorporated by reference, see 
Sec.  63.14). You may conduct panel testing on representative coatings 
as described in ``Protocol for Determining the Daily Volatile Organic 
Compound Emission Rate of Automobile and Light-Duty Truck Topcoat 
Operations,'' EPA-450/3-88-018. The results of these panel testing 
procedures are in units of mass of VOC per volume of coating solids 
deposited and must be converted to a percent value for use in this 
subpart. If you panel test representative coatings, then you may 
convert the panel test result for each representative coating either to 
a unique percent capture efficiency for each coating grouped with that 
representative coating by using coating specific values for the volume 
of coating solids deposited per volume of coating used, mass of VOC per 
volume of coating, volume fraction solids, transfer efficiency, density 
and mass fraction VOC in Equations 4 through 6 of this section; or to a 
composite percent capture efficiency for the group of coatings by using 
composite values for the group of coatings for the volume of coating 
solids deposited per volume of coating used and for the mass of VOC per 
volume of coating, and average values for the group of coatings for 
volume fraction solids, transfer efficiency, density and mass fraction 
VOC in Equations 4 through 6 of this section. If you panel test each 
coating, then you must convert the panel test result for each coating 
to a unique percent capture efficiency for that coating by using 
coating specific values for the volume of coating solids deposited per 
volume of coating used, mass of VOC per volume of coating, volume 
fraction solids, transfer efficiency, density, and mass fraction VOC in 
Equations 4 through 6 of this section. Panel test results expressed in 
units of mass of VOC per volume of coating solids deposited must be 
converted to percent capture efficiency using Equation 4 of this 
section. An alternative for using panel test results expressed in units 
of mass of VOC per mass of coating solids deposited is presented in 
paragraph (e)(3) of this section.

15. Section 63.3166 is amended by revising the introductory text and 
paragraphs (a)(1) through (4) and (b) introductory text, and adding 
paragraph (b)(4) to read as follows:

Sec.  63.3166  How do I determine the add-on control device emission 
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec.  63.3160, 
Sec.  63.3163, or Sec.  63.3171. You must conduct three test runs as 
specified in Sec.  63.7(e)(3), and each test run must last at least 1 
hour.
    (a) * * *
    (1) Use EPA Method 1 or 1A of appendix A-1 to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use EPA Method 2, 2A, 2C, 2D, or 2F of appendix A-1, or 2G of 
appendix A-2 to 40 CFR part 60, as appropriate, to measure gas 
volumetric flow rate.
    (3) Use EPA Method 3, 3A, or 3B of appendix A-2 to 40 CFR part 60, 
as appropriate, for gas analysis to determine dry molecular weight. The 
ANSI/ASME PTC 19.10-1981 (incorporated by reference, see Sec.  63.14), 
may be used as an alternative to EPA Method 3B.

[[Page 41132]]

    (4) Use EPA Method 4 of appendix A-3 to 40 CFR part 60 to determine 
stack gas moisture.

    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either EPA Method 25 or 25A of appendix A-7 to 40 CFR part 60, as 
specified in paragraphs (b)(1) through (4) of this section. You must 
use the same method for both the inlet and outlet measurements.

16. Section 63.3167 is amended by revising the section heading, the 
introductory text, and paragraph (f)(1) to read as follows:

Sec.  63.3167  How do I establish the add-on control device operating 
limits during performance tests?

    During the performance tests required by Sec. Sec.  63.3160, 
63.3163, and 63.3171 (and described in Sec. Sec.  63.3164 and 63.3166), 
you must establish the operating limits required by Sec.  63.3093 
according to this section, unless you have received approval for 
alternative monitoring and operating limits under Sec.  63.8(f) as 
specified in Sec.  63.3093.

    (f) * * *
    (1) During the capture efficiency determination required by 
Sec. Sec.  63.3160 and 63.3163 and described in Sec. Sec.  63.3164 and 
63.3165, you must monitor and record either the gas volumetric flow 
rate or the duct static pressure for each separate capture device in 
your emission capture system at least once every 15 minutes during each 
of the three test runs at a point in the duct between the capture 
device and the add-on control device inlet.

17. Section 63.3168 is amended by revising paragraphs (a)(4) through 
(7) and (c)(3) introductory text to read as follows:

Sec.  63.3168  What are the requirements for continuous parameter 
monitoring system installation, operation, and maintenance?

    (a) * * *
    (4) You must maintain the CPMS at all times in accordance with 
Sec.  63.3100(d) and have readily available necessary parts for routine 
repairs of the monitoring equipment.
    (5) Before January 5, 2021, you must operate the CPMS and collect 
emission capture system and add-on control device parameter data at all 
times that a controlled coating operation is operating, except during 
monitoring malfunctions, associated repairs, and required quality 
assurance or control activities (including, if applicable, calibration 
checks and required zero and span adjustments). On and after January 5, 
2021, you must operate the CPMS and collect emission capture system and 
add-on control device parameter data at all times that a controlled 
coating operation is operating in accordance with Sec.  63.3100(d).
    (6) Before January 5, 2021, you must not use emission capture 
system or add-on control device parameter data recorded during 
monitoring malfunctions, associated repairs, out-of-control periods, or 
required quality assurance or control activities when calculating data 
averages. You must use all the data collected during all other periods 
in calculating the data averages for determining compliance with the 
emission capture system and add-on control device operating limits. On 
and after January 5, 2021, startups and shutdowns are normal operation 
for this source category. Emissions from these activities are to be 
included when determining if the standards specified in Sec. Sec.  
63.3090, 63.3091, 63.3092, 63.4292, and 63.4293 are being attained. You 
must not use emission capture system or add-on control device parameter 
data recorded during monitoring malfunctions, associated repairs, out-
of-control periods, or required quality assurance or control activities 
when calculating data averages. You must use all the data collected 
during all other periods in calculating the data averages for 
determining compliance with the emission capture system and add-on 
control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Before January 5, 2021, any 
period for which the monitoring system is out of control and data are 
not available for required calculations is a deviation from the 
monitoring requirements. On and after January 5, 2021, except for 
periods of required quality assurance or control activities, any period 
during which the CPMS fails to operate and record data continuously as 
required by paragraph (a)(1) of this section, or generates data that 
cannot be included in calculating averages as specified in this 
paragraph (a)(7) constitutes a deviation from the monitoring 
requirements.
* * * * *
    (c) * * *
    (3) For all thermal oxidizers and catalytic oxidizers, you must 
meet the requirements in paragraphs (a)(1) through (6) and (c)(3)(i) 
through (vii) of this section for each gas temperature monitoring 
device. For the purposes of this paragraph (c)(3), a thermocouple is 
part of the temperature sensor.

18. Section 63.3171 is amended by revising paragraphs (a) and (e)(3) to 
read as follows:

Sec.  63.3171  How do I demonstrate initial compliance?

    (a) You must meet all of the requirements of this section to 
demonstrate initial compliance. To demonstrate initial compliance, the 
organic HAP emissions from the combined primer-surfacer, topcoat, final 
repair, glass bonding primer, and glass bonding adhesive operations 
plus all coatings and thinners, except for deadener materials and for 
adhesive and sealer materials that are not components of glass bonding 
systems, used in coating operations added to the affected source 
pursuant to Sec.  63.3082(c) must meet the applicable emission 
limitation in Sec.  63.3090(b) or Sec.  63.3091(b); the organic HAP 
emissions from the electrodeposition primer operation must meet the 
applicable emissions limitations in Sec.  63.3092(a) or (b); and you 
must meet the applicable operating limits and work practice standards 
in Sec. Sec.  63.3093 and 63.3094.
* * * * *
    (e) * * *
    (3) 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) and (2) 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, and at 
1.0 percent by mass or more for other compounds. If there is a 
disagreement between such information and results of a test conducted 
according to paragraph (e)(1) or (2) of this section, then the test 
method results will take precedence unless after consultation, the 
facility demonstrates to the satisfaction of the enforcement authority 
that the facility's data are correct.

22. Appendix A to Subpart IIII of part 63 is amended by revising 
sections 2.1, 2.2, and 4.1 and the definitions of ``Ws, i'' 
and ``Wvocc, i'' in Equation A-6 in section 4.2 to read as 
follows:

Appendix A to Subpart IIII of Part 63--Determination of Capture 
Efficiency of Automobile and Light-Duty Truck Spray Booth Emissions 
From Solvent-Borne Coatings Using Panel Testing

* * * * *
    2.1 You may conduct panel testing to determine the capture 
efficiency of spray booth emissions. You must follow the 
instructions and calculations in this appendix A, and use the panel 
testing procedures in ASTM Method D5087-02 (incorporated by 
reference, see Sec.  63.14), or the guidelines presented in 
``Protocol for Determining the Daily Volatile Organic Compound 
Emission Rate of Automobile and Light-Duty Truck Topcoat 
Operations,'' EPA-450/3-88-018 (incorporated by reference, see Sec.  
63.14). You must weigh panels at the points described in section 2.5 
of this appendix A and perform calculations as described in sections 
3 and 4 of this appendix A. You may

[[Page 41138]]

conduct panel tests on the production paint line in your facility or 
in a laboratory simulation of the production paint line in your 
facility.
    2.2 You may conduct panel testing on representative coatings as 
described in ``Protocol for Determining the Daily Volatile Organic 
Compound Emission Rate of Automobile and Light-Duty Truck Topcoat 
Operations,'' EPA-450/3-88-018 (incorporated by reference, see Sec.  
63.14). If you panel test representative coatings, then you may 
calculate either a unique percent capture efficiency value for each 
coating grouped with that representative coating, or a composite 
percent capture efficiency value for the group of coatings. If you 
panel test each coating, then you must convert the panel test result 
for each coating to a unique percent capture efficiency value for 
that coating.
* * * * *
    4.1 If you panel test representative coatings, then you may 
convert the panel test result for each representative coating from 
section 3.3 of this appendix A either to a unique percent capture 
efficiency value for each coating grouped with that representative 
coating by using coating specific values for the mass fraction 
coating solids and mass fraction VOC in section 4.2 of this appendix 
A, or to a composite percent capture efficiency value for the group 
of coatings by using the average values for the group of coatings 
for mass fraction coating solids and mass fraction VOC in section 
4.2 of this appendix A. If you panel test each coating, then you 
must convert the panel test result for each coating to a unique 
percent capture efficiency value by using coating specific values 
for the mass fraction coating solids and mass fraction VOC in 
section 4.2 of this appendix A. The mass fraction of VOC in the 
coating and the mass fraction of solids in the coating must be 
determined by EPA Method 24 (appendix A-7 to 40 CFR part 60) or by 
following the guidelines for combining analytical VOC content and 
formulation solvent content presented in ``Protocol for Determining 
the Daily Volatile Organic Compound Emission Rate of Automobile and 
Light-Duty Truck Topcoat Operations,'' EPA-450/3-88-018 
(incorporated by reference, see Sec.  63.14).
    4.2 * * *

or average mass fraction of coating solids for the group of coatings 
including coating, i, grams coating solids per gram coating, 
determined by EPA Method 24 (appendix A-7 to 40 CFR part 60) or by 
following the guidelines for combining analytical VOC content and 
formulation solvent content presented in ``Protocol for Determining 
the Daily Volatile Organic Compound Emission Rate of Automobile and 
Light-Duty Truck Topcoat Operations,'' EPA-450/3-88-018 
(incorporated by reference, see Sec.  63.14).
Wvocc, i = Mass fraction of VOC in coating, i, or average 
mass fraction of VOC for the group of coatings including coating, i,

during periods of SSM and except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to Sec.  
63.3961(j). On or after January 5, 2021, the coating operation(s) must 
be in compliance with the operating limits for emission capture systems 
and add-on control devices required by Sec.  63.3892 at all times, 
except for solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec.  63.3961(j).
* * * * *
    (b) Before January 5, 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 January 5, 2021, 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 January 5, 2021, if your affected source uses an 
emission capture system and add-on control device, you must develop a 
written SSMP 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. On and after January 5, 2021, the SSMP is not 
required.

OAPQS/CORE CBI Office, Attention: Group Leader, Measurement Policy 
Group, MD C404-02, 4930 Old Page Rd., Durham, NC 27703. The same ERT or 
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) Initial notification reports. On and after January 5, 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. Sec.  63.9(h) and 63.3910(c) to the EPA via the 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 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) Semiannual compliance reports. On and after January 5, 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 the 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) Reporting during EPA system outages. If you are required to 
electronically submit a report through the 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 the 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 the EPA system outage 
and allow an extension to the reporting deadline is solely within the 
discretion of the Administrator.
    (h) Reporting during force majeure events. 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

[[Page 41141]]

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.

25. Section 63.3930 is amended by revising paragraphs (j), (k) 
introductory text, and (k)(1) and (2) to read as follows:

Sec.  63.3930  What records must I keep?

* * * * *
    (j) Before January 5, 2021, you must keep records of the date, 
time, and duration of each deviation. On and after January 5, 2021, for 
each deviation from an emission limitation reported under Sec.  
63.3920(a)(5) through (7), 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.  63.3920(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.  63.3920(a)(5) through (7).
    (3) An estimate of the quantity of each regulated pollutant emitted 
over any applicable emission limit in Sec.  63.3890 or any applicable 
operating limit in table 1 to this subpart, and a description of the 
method used to calculate the estimate, as reported under Sec.  
63.3920(a)(5) through (7).
    (4) A record of actions taken to minimize emissions in accordance 
with Sec.  63.3900(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 January 5, 2021, for each deviation, a record of whether 
the deviation occurred during a period of SSM. On and after January 5, 
2021, a record of whether the deviation occurred during a period of SSM 
is not required.
    (2) Before January 5, 2021, the records in Sec.  63.6(e)(3)(iii) 
through (v) related to SSM. On and after January 5, 2021, the records 
in Sec.  63.6(e)(3)(iii) through (v) related to SSM are not required.

26. Section 63.3931 is amended by revising paragraph (a) to read as 
follows:

Sec.  63.3931  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. On and after January 5, 2021, 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.

27. Section 63.3941 is amended by revising paragraphs (a)(1)(i), 
(a)(4), (b)(1), the definition of ``Davg'' in Equation 1 of 
paragraph (b)(4), and paragraph (c) to read as follows:

Sec.  63.3941  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 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 (e.g., 0.3791).
* * * * *
    (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 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. For 
reactive adhesives in which some of the HAP react to form solids and 
are not emitted to the atmosphere, you may rely on manufacturer's data 
that expressly states the organic HAP or volatile matter mass fraction 
emitted. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence 
unless, after consultation, you demonstrate to the satisfaction of the 
enforcement agency that the formulation data are correct.
* * * * *
    (b) * * *
    (1) ASTM Method D2697-03 (Reapproved 2014) or D6093-97 (Reapproved 
2016). You may use ASTM D2697-03 (Reapproved 2014) (incorporated by 
reference, see Sec.  63.14), or D6093-97 (Reapproved 2016) 
(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.
* * * * *
    (4) * * *

Davg = Average density of volatile matter in the coating, 
grams volatile matter per liter volatile matter, determined from 
test results using ASTM D1475-13 (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 unless, after consultation you 
demonstrate to the satisfaction of the enforcement agency that the 
formulation data are correct.

    (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 (incorporated by reference, see Sec.  63.14), information 
from the supplier or manufacturer of the material, or specific gravity 
data for pure chemicals. If there is disagreement between ASTM D1475-13 
test results and the supplier's or manufacturer's information, the test 
results will take precedence unless, after consultation you demonstrate 
to the satisfaction of the enforcement agency that the formulation data 
are correct.

28. Section 63.3951 is amended by revising paragraph (c) to read as 
follows:

[[Page 41142]]

Sec.  63.3951  How do I demonstrate initial compliance with the 
emission limitations?

* * * * *
    (c) Determine the density of each material. Determine the density 
of each liquid coating, thinner and/or other additive, and cleaning 
material used during each month from test results using ASTM D1475-13 
or ASTM D2111-10 (Reapproved 2015) (both incorporated by reference, see 
Sec.  63.14), information from the supplier or manufacturer of the 
material, or reference sources providing density or specific gravity 
data for pure materials. If you are including powder coatings in the 
compliance determination, determine the density of powder coatings, 
using ASTM D5965-02 (Reapproved 2013) (incorporated by reference, see 
Sec.  63.14), or information from the supplier. If there is 
disagreement between ASTM D1475-13 or ASTM D2111-10 (Reapproved 2015) 
test results and other such information sources, the test results will 
take precedence unless, after consultation you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct. If you purchase materials or monitor consumption by weight 
instead of volume, you do not need to determine material density. 
Instead, you may use the material weight in place of the combined terms 
for density and volume in Equations 1A, 1B, 1C, and 2 of this section.

29. Section 63.3960 is amended by revising paragraphs (a)(1) and (4), 
(b)(1), and (c) introductory text to read as follows:

Sec.  63.3960  By what date must I conduct performance tests and other 
initial compliance demonstrations?

    (a) * * *
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec.  63.3883. Except for solvent recovery systems 
for which you conduct liquid-liquid material balances according to 
Sec.  63.3961(j), you must conduct according to the schedule in 
paragraphs (a)(1)(i) and (ii) of this section initial and periodic

31. Section 63.3963 is amended by revising paragraph (f) and adding 
paragraph (i) to read as follows:

Sec.  63.3963  How do I demonstrate continuous compliance with the 
emission limitations?

* * * * *
    (f) As part of each semiannual compliance report required in Sec.  
63.3920, you must identify the coating operation(s) for which you used 
the emission rate with add-on controls option. If there were no 
deviations from the emission limits in Sec.  63.3890, the operating 
limits in Sec.  63.3892, and the work practice standards in Sec.  
63.3893, submit a statement that you were in compliance with the 
emission limitations during the reporting period because the organic 
HAP emission rate for each compliance period was less than or equal to 
the applicable emission limit in Sec.  63.3890, and you achieved the 
operating limits required by Sec.  63.3892 and the work practice 
standards required by Sec.  63.3893 during each compliance period.
* * * * *
    (i) On and after January 5, 2021, deviations that occur due to 
malfunction of the emission capture system, add-on control device, or 
coating operation that may affect emission capture or control device 
efficiency are required to operate in accordance with Sec.  63.3900(b). 
The Administrator will determine whether the deviations are violations 
according to the provisions in Sec.  63.3900(b).

32. Section 63.3964 is amended by revising paragraphs (a) introductory 
text and (a)(1) to read as follows:

Sec.  63.3964  What are the general requirements for performance tests?

    (a) Before January 5, 2021, you must conduct each performance test 
required by Sec.  63.3960 according to the requirements in Sec.  
63.7(e)(1) 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). On and after January 5, 2021, you must conduct each 
performance test required by Sec.  63.3960 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 periods of 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.

    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either EPA Method 25 or 25A of appendix A-7 to 40 CFR part 60.
    (1) Use EPA Method 25 of appendix A-7 to 40 CFR part 60 if the add-
on control device is an oxidizer and you expect the total gaseous 
organic concentration as carbon to be more than 50 parts per million 
(ppm) at the control device outlet.
    (2) Use EPA Method 25A of appendix A-7 to 40 CFR part 60 if the 
add-on control device is an oxidizer and you expect the total gaseous 
organic concentration as carbon to be 50 ppm or less at the control 
device outlet.
    (3) Use EPA Method 25A of appendix A-7 to 40 CFR part 60 if the

35. Section 63.3967 is amended by revising paragraphs (a)(1) and (2), 
(b)(1) through (3), (d)(1) and (2), and (e)(1) through (4) to read as 
follows:

Sec.  63.3967  How do I establish the emission capture system and add-
on control device operating limits during the performance test?

* * * * *
    (a) * * *
    (1) During performance tests, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of 
the three test runs. You must monitor the temperature in the firebox of 
the thermal oxidizer or immediately downstream of the firebox before 
any substantial heat exchange occurs.
    (2) For each performance test, use the data collected during the 
performance test to calculate and record the average combustion 
temperature maintained during the performance test. This average 
combustion temperature is the minimum operating limit for your thermal 
oxidizer.
    (b) * * *
    (1) During performance tests, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) For each performance test, 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. These are the 
minimum operating limits for your catalytic oxidizer.
    (3) You must monitor the temperature at the inlet to the catalyst 
bed and implement a site-specific inspection and maintenance plan for 
your catalytic oxidizer as specified in paragraph (b)(4) of this 
section. During the performance test, you must monitor and record the 
temperature just before the catalyst bed at least once every 15 minutes 
during each of the three test runs. For each performance test, use the 
data collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
* * * * *
    (d) * * *
    (1) During performance tests, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) For each performance test, use the data collected during the 
performance test to calculate and record the average condenser outlet 
(product side) gas temperature maintained during the performance test. 
This average condenser outlet gas temperature is the maximum operating 
limit for your condenser.
    (e) * * *
    (1) During performance tests, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) For each performance test, use the data collected during the 
performance test to calculate and record the average temperature. This 
is the minimum operating limit for the desorption concentrate gas 
stream temperature.
    (3) During performance tests, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least 
once every 15 minutes during each of the three runs of the performance 
test.
    (4) For each performance test, use the data collected during the 
performance test to calculate and record the average pressure drop. 
This is the minimum operating limit for the dilute stream across the 
concentrator.

36. Section 63.3968 is amended by revising paragraphs (a)(4), (5), and 
(7), and (c)(3) introductory text to read as follows:

Sec.  63.3968  What are the requirements for continuous parameter 
monitoring system installation, operation, and maintenance?

    (a) * * *
    (4) Before January 5, 2021, you must maintain the CPMS at all times 
and have available necessary parts for routine repairs of the 
monitoring equipment. On and after January 5, 2021, you must maintain 
the CPMS at all times in accordance with Sec.  63.3900(b) and keep 
necessary parts readily available for routine repairs of the monitoring 
equipment.
    (5) Before January 5, 2021, you must operate the CPMS and collect 
emission capture system and add-on control device parameter data at all 
times that a controlled coating operation is operating, except during 
monitoring malfunctions, associated repairs, and required quality 
assurance or control activities (including, if applicable, calibration 
checks and required zero and span adjustments). On and after January 5, 
2021, you must operate the CPMS and collect emission capture system and 
add-on control device parameter data at all times in accordance with 
Sec.  63.3900(b).
* * * * *
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Before January 5, 2021, any 
period for which the monitoring system is out-of-control and data are 
not available for required calculations is a deviation from the 
monitoring requirements. On and after January 5, 2021, except for 
periods of required quality assurance or control activities, any period 
for which the CPMS fails to operate and record data continuously as 
required by paragraph (a)(5) of this section, or generates data that 
cannot be included in calculating averages as specified in (a)(6) of 
this section constitutes a deviation from the monitoring requirements.
* * * * *
    (c) * * *
    (3) For all thermal oxidizers and catalytic oxidizers, you must 
meet the requirements in paragraphs (a) and (c)(3)(i) through (v) of 
this section for each gas temperature monitoring device. For the 
purposes of this paragraph (c)(3), a thermocouple is part of the 
temperature sensor.

emission rate with add-on controls option, except those for which you 
use a solvent recovery system and conduct a liquid-liquid material 
balance according to Sec.  63.4561(j), you must meet the operating 
limits specified in table 1 to this subpart. These operating limits 
apply to the emission capture and control systems on the coating 
operation(s) for which you use this option, and you must establish the 
operating limits during the performance tests required in Sec.  63.4560 
according to the requirements in Sec.  63.4567. You must meet the 
operating limits established during the most recent performance tests 
required in Sec.  63.4560 at all times after you establish them.

    (i) The coating operation(s) must be in compliance with the 
applicable emission limit in Sec.  63.4490 at all times.
    (ii) The coating operation(s) must be in compliance with the 
operating limits for emission capture systems and add-on control 
devices required by Sec.  63.4492 at all times, except for solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to Sec.  63.4561(j).
* * * * *
    (b) Before January 5, 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 January 5, 2021, 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 January 5, 2021, if your affected source uses an 
emission capture system and add-on control device, you must develop a 
written SSMP 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. On and after January 5, 2021, the SSMP is not 
required.

[[Page 41152]]

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) Initial notification reports. On and after January 5, 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.  63.4510(c) to the EPA via the 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 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) Semiannual compliance reports. On and after January 5, 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 the CEDRI. (CEDRI 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) Reporting during EPA system outages. If you are required to 
electronically submit a report through the 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 the 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 the EPA system outage 
and allow an extension to the reporting deadline is solely within the 
discretion of the Administrator.
    (h) Reporting during force majeure events. 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 63.4530 is amended by revising paragraphs (h), (i) 
introductory text, and (i)(1) and (2) to read as follows:

Sec.  63.4530  What records must I keep?

* * * * *
    (h) Before January 5, 2021, you must keep records of the date, 
time, and duration of each deviation. On and after January 5, 2021, for 
each deviation from an emission limitation reported under Sec.  
63.4520(a)(5) through (7), a record of the information specified in 
paragraphs (h)(1) through (4) of this section, as applicable.
    (1) The date, time, and duration of the deviation, as reported 
under Sec.  63.4520(a)(5) through (7).

[[Page 41153]]

    (2) A list of the affected sources or equipment for which the 
deviation occurred and the cause of the deviation, as reported under 
Sec.  63.4520(a)(5) through (7).
    (3) An estimate of the quantity of each regulated pollutant emitted 
over any applicable emission limit in Sec.  63.4490 or any applicable 
operating limit in Table 1 to this subpart, and a description of the 
method used to calculate the estimate, as reported under Sec.  
63.4520(a)(5) through (7).
    (4) A record of actions taken to minimize emissions in accordance 
with Sec.  63.4500(b) and any corrective actions taken to return the 
affected unit to its normal or usual manner of operation.
    (i) If you use the emission rate with add-on controls option, you 
must also keep the records specified in paragraphs (i)(1) through (8) 
of this section.
    (1) Before January 5, 2021, for each deviation, a record of whether 
the deviation occurred during a period of SSM. On and after January 5, 
2021, a record of whether the deviation occurred during a period of SSM 
is not required.
    (2) Before January 5, 2021, the records in Sec.  63.6(e)(3)(iii) 
through (v) related to SSM. On and after January 5, 2021, the records 
in Sec.  63.6(e)(3)(iii) through (v) related to SSM are not required.

46. Section 63.4531 is amended by revising paragraph (a) to read as 
follows:

Sec.  63.4531  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. On and after January 5, 2021, 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 63.4541 is amended by revising paragraphs (a)(1)(i) and 
(a)(2) and (4) to read as follows:

Sec.  63.4541  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 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 (e.g., 0.3791).
* * * * *
    (2) EPA Method 24 (appendix A-7 to 40 CFR part 60). For coatings, 
you may use EPA Method 24 to determine the mass fraction of nonaqueous 
volatile matter and use that value as a substitute for mass fraction of 
organic HAP. As an alternative to using EPA Method 24, you may use ASTM 
D2369-10 (Reapproved 2015)\e\ (incorporated by reference, see Sec.  
63.14). For reactive adhesives in which some of the HAP react to form 
solids and are not emitted to the atmosphere, you may use the 
alternative method contained in appendix A to this subpart, rather than 
EPA Method 24. You may use the volatile fraction that is emitted, as 
measured by the alternative method in appendix A to this subpart, as a 
substitute for the mass fraction of organic HAP.
* * * * *
    (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 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. For 
reactive adhesives in which some of the HAP react to form solids and 
are not emitted to the atmosphere, you may rely on manufacturer's data 
that expressly states the organic HAP or volatile matter mass fraction 
emitted. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence 
unless, after consultation you demonstrate to the satisfaction of the 
enforcement agency that the formulation data are correct.
* * * * *

48. Section 63.4551 is amended by revising paragraph (c) to read as 
follows:

Sec.  63.4551  How do I demonstrate initial compliance with the 
emission limitations?

* * * * *
    (c) Determine the density of each material. Determine the density 
of each liquid coating, thinner and/or other additive, and cleaning 
material used during each month from test results using ASTM D1475-13 
or ASTM D2111-10 (Reapproved 2015) (both incorporated by reference, see 
Sec.  63.14), information from the supplier or manufacturer of the 
material, or reference sources providing density or specific gravity 
data for pure materials. If there is disagreement between ASTM D1475-13 
or ASTM D2111-10 (Reapproved 2015) and other such information sources, 
the test results will take precedence unless, after consultation you 
demonstrate to the satisfaction of the enforcement agency that the 
formulation data are correct. If you purchase materials or monitor 
consumption by weight instead of volume, you do not need to determine 
material density. Instead, you may use the material weight in place of 
the combined terms for density and volume in Equations 1A, 1B, 1C, and 
2 of this section.

the volatile organic matter mass fraction using EPA Method 24 of 40 CFR 
part 60, appendix A-7, ASTM D2369-10 (Reapproved 2015)\e\ (incorporated 
by reference, see Sec.  63.14), or an EPA approved alternative method. 
Alternatively, you may determine the volatile organic matter mass 
fraction using information provided by the manufacturer or supplier of 
the coating. In the event of any inconsistency between information 
provided by the manufacturer or supplier and the results of EPA Method 
24 of 40 CFR part 60, appendix A-7, ASTM D2369-10 (Reapproved 2015)\e\, 
or an approved alternative method, the test method results will take 
precedence unless, after consultation you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.

    (n) Compliance demonstration. The organic HAP emission rate for the 
initial compliance period, calculated using Equation 5 of this section, 
must be less than or equal to the applicable emission limit for each 
subcategory in Sec.  63.4490 or the predominant activity or facility-
specific emission limit allowed in Sec.  63.4490(c). You must keep all 
records as required by Sec. Sec.  63.4530 and 63.4531. As part of the 
notification of compliance status required by Sec.  63.4510, you must 
identify the coating operation(s) for which you used the emission rate 
with add-on controls option and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate was less than or equal to the applicable emission limit in Sec.  
63.4490, and for control devices other than solvent recovery system 
using a liquid-liquid material balance, you achieved the operating 
limits required by Sec.  63.4492 and the work practice standards 
required by Sec.  63.4493.

Sec.  63.4563  How do I demonstrate continuous compliance with the 
emission limitations?

* * * * *
    (f) As part of each semiannual compliance report required in Sec.  
63.4520, you must identify the coating operation(s) for which you used 
the emission rate with add-on controls option. If there were no 
deviations from the emission limits in Sec.  63.4490, the operating 
limits in Sec.  63.4492, and the work practice standards in Sec.  
63.4493, submit a statement that you were in compliance with the 
emission limitations during the reporting period because the organic 
HAP emission rate for each compliance period was less than or equal to 
the applicable emission limit in Sec.  63.4490, and you achieved the 
operating limits required by Sec.  63.4492 and the work practice 
standards required by Sec.  63.4493 during each compliance period.
    (g) On and after January 5, 2021, deviations that occur due to 
malfunction of the emission capture system, add-on control device, or 
coating operation that may affect emission capture or control device 
efficiency are required to operate in accordance with Sec.  63.4500(b). 
The Administrator will determine whether the deviations are violations 
according to the provisions in Sec.  63.4500(b).

55. Section 63.4567 is amended by revising the introductory text and 
paragraphs (a)(1) and (2), (b)(1) through (3), (c)(1), (d)(1) and (2), 
and (e)(1) through (4) to read as follows:

Sec.  63.4567  How do I establish the emission capture system and add-
on control device operating limits during the performance test?

    During performance tests required by Sec.  63.4560 and described in 
Sec. Sec.  63.4564, 63.4565, and 63.4566, you must establish the 
operating limits required by Sec.  63.4492 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec.  63.8(f) as specified in Sec.  63.4492.
    (a) * * *
    (1) During performance tests, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of 
the three test runs. You must monitor the temperature in the firebox of 
the thermal oxidizer or immediately downstream of the firebox before 
any substantial heat exchange occurs.
    (2) For each performance test, use the data collected during the 
performance test to calculate and record the average combustion 
temperature maintained during the performance test. This average 
combustion temperature is the minimum operating limit for your thermal 
oxidizer.
    (b) * * *
    (1) During performance tests, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) For each performance test, 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. These are the 
minimum operating limits for your catalytic oxidizer.
    (3) You must monitor the temperature at the inlet to the catalyst 
bed and implement a site-specific inspection and

[[Page 41156]]

maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During performance tests, you must monitor and 
record the temperature just before the catalyst bed at least once every 
15 minutes during each of the three test runs. For each performance 
test, use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed during 
the performance test. This is the minimum operating limit for your 
catalytic oxidizer.
* * * * *
    (c) * * *
    (1) During performance tests, you must monitor and record the total 
regeneration desorbing gas (e.g., steam or nitrogen) mass flow for each 
regeneration cycle, and the carbon bed temperature after each carbon 
bed regeneration and cooling cycle for the regeneration cycle either 
immediately preceding or immediately following the performance test.
* * * * *
    (d) * * *
    (1) During performance tests, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs of the performance test.
    (2) For each performance test, use the data collected during the 
performance test to calculate and record the average condenser outlet 
(product side) gas temperature maintained during the performance test. 
This average condenser outlet gas temperature is the maximum operating 
limit for your condenser.
    (e) * * *
    (1) During performance tests, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) For each performance test, use the data collected during the 
performance test to calculate and record the average temperature. This 
is the minimum operating limit for the desorption concentrate gas 
stream temperature.
    (3) During each performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least 
once every 15 minutes during each of the three runs of the performance 
test.
    (4) For each performance test, use the data collected during the 
performance test to calculate and record the average pressure drop. 
This is the minimum operating limit for the dilute stream across the 
concentrator.

56. Section 63.4568 is amended by revising paragraphs (a)(4), (5), and 
(7) and (c)(3) introductory text to read as follows:

Sec.  63.4568  What are the requirements for continuous parameter 
monitoring system installation, operation, and maintenance?

    (a) * * *
    (4) Before January 5, 2021, you must maintain the CPMS at all times 
and have available necessary parts for routine repairs of the 
monitoring equipment. On and after January 5, 2021, you must maintain 
the CPMS at all times in accordance with Sec.  63.4500(b) and keep 
necessary parts readily available for routine repairs of the monitoring 
equipment.
    (5) Before January 5, 2021, you must operate the CPMS and collect 
emission capture system and add-on control device parameter data at all 
times that a controlled coating operation is operating, except during 
monitoring malfunctions, associated repairs, and required quality 
assurance or control activities (including, if applicable, calibration 
checks and required zero and span adjustments). On and after January 5, 
2021, you must operate the CPMS and collect emission capture system and 
add-on control device parameter data at all times in accordance with 
Sec.  63.4500(b).
* * * * *
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Before January 5, 2021, any 
period for which the monitoring system is out-of-control and data are 
not available for required calculations is a deviation from the 
monitoring requirements. On and after January 5, 2021, except for 
periods of required quality assurance or control activities, any period 
for which the CPMS fails to operate and record data continuously as 
required by paragraph (a)(5) of this section, or generates data that 
cannot be included in calculating averages as specified in (a)(6) of 
this section constitutes a deviation from the monitoring requirements.
* * * * *
    (c) * * *
    (3) For all thermal oxidizers and catalytic oxidizers, you must 
meet the requirements in paragraphs (a) and (c)(3)(i) through (v) of 
this section for each gas temperature monitoring device. For the 
purposes of this paragraph (c)(3), a thermocouple is part of the 
temperature sensor.

60. Appendix A to Subpart PPPP of Part 63 is amended by revising 
section 1.2 to read as follows:

Appendix A to Subpart PPPP of Part 63--Determination of Weight Volatile 
Matter Content and Weight Solids Content of Reactive Adhesives

* * * * *
    1.2 Principle: One-part and multiple-part reactive adhesives 
undergo a reactive conversion from liquid to solid during the 
application and assembly process. Reactive adhesives are applied to 
a single surface, but then are usually quickly covered with another 
mating surface to achieve a bonded assembly. The monomers employed 
in such systems typically react and are converted to non-volatile 
solids. If left uncovered, as in a EPA Method 24 (or ASTM D2369-10 
(Reapproved 2015)\e\) test, the reaction is inhibited by the 
presence of oxygen and volatile loss of the reactive components 
competes more heavily with the cure reaction. If this were to happen 
under normal use conditions, the adhesives would not provide 
adequate performance. This method minimizes this undesirable 
deterioration of the adhesive performance.

61. Section 63.4965 is amended by adding paragraphs (b)(1) through (3) 
to read as follows:

Sec.  63.4965  How do I determine the add-on control device emission 
destruction or removal efficiency?

* * * * *
    (b) * * *
    (1) Use EPA Method 25 to appendix A-7 to part 60 if the add-on 
control device is an oxidizer and you expect the total gaseous organic 
concentration as carbon to be more than 50 parts per million (ppm) at 
the control device outlet.
    (2) Use EPA Method 25A to appendix A-7 to part 60 if the add-on 
control device is an oxidizer and you expect the total gaseous organic 
concentration as carbon to be 50 ppm or less at the control device 
outlet.
    (3) Use EPA Method 25A to appendix A-7 to part 60 if the add-on 
control device is not an oxidizer.
