National Emission Standards for Hazardous Air Pollutants: Surface 
Coating of Large Appliances; Printing, Coating, and Dyeing of Fabrics 
and Other Textiles; and Surface Coating of Metal Furniture Residual 
Risk and Technology Reviews

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action on the residual risk and technology reviews (RTRs) conducted for 
the Surface Coating of Large Appliances; the Printing, Coating, and 
Dyeing of Fabrics and Other Textiles; and the Surface Coating of Metal 
Furniture source categories regulated under national emission standards 
for hazardous air pollutants (NESHAP). In addition, we are taking final 
action addressing emissions during periods of startup, shutdown, and 
malfunction (SSM); electronic reporting for 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. Additionally, several miscellaneous 
technical amendments will be 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.

DATES: This final rule is effective on March 15, 2019. The 
incorporation by reference of certain publications listed in this rule 
is approved by the Director of the Federal Register as of March 15, 
2019.

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 May 14, 2019. Under CAA section 307(b)(2), the 
requirements established by these final rules 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, EPA 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 reduce the volume of or 
eliminate HAP emissions through process changes, substitution of 
materials, or other modifications; enclose systems or processes to 
eliminate emissions; collect, capture, or treat HAP when released from 
a process, stack, storage, or fugitive emissions point; are design, 
equipment, work practice, or operational standards; or 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

[[Page 9593]]

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 these final rules, see 83 Federal Register (FR) 46262, September 
12, 2018.
---------------------------------------------------------------------------

    \1\ The Court has affirmed this approach of implementing CAA 
section 112(f)(2)(A): NRDC v. EPA, 529 F.3d 1077, 1083 (D.C. Cir. 
2008) (``If EPA determines that the existing technology-based 
standards provide an `ample margin of safety,' then the Agency is 
free to readopt those standards during the residual risk 
rulemaking.'').
---------------------------------------------------------------------------

B. What are the source categories and how does the NESHAP regulate its 
HAP emissions?

1. What is the Surface Coating of Large Appliances source category and 
how does the current NESHAP regulate its HAP emissions?
    The EPA promulgated the Surface Coating of Large Appliances source 
category NESHAP on July 23, 2002 (67 FR 48254). The standards are 
codified at 40 CFR part 63, subpart NNNN. The Surface Coating of Large 
Appliances industry consists of facilities that are engaged in the 
surface coating of a large appliance part or product. The source 
category covered by this MACT standard currently includes ten 
facilities.
    The Surface Coating of Large Appliances NESHAP (40 CFR 63.4081) 
defines a ``large appliance part or product'' as ``a component of a 
large appliance product manufactured for household, recreational, 
institutional, commercial, or industrial use,'' and defines a coating 
as a ``material that is applied to a substrate for decorative, 
protective or functional purposes.'' This source category is further 
described in the September 12, 2018, RTR proposal. See 83 FR 46262, 
46266-67.
    The primary HAP emitted from this source category are organic HAP 
and include xylene, glycol ethers, toluene, methanol, ethyl benzene, 
methylene chloride, and methyl isobutyl ether with approximately 80 
percent of the HAP emissions coming from coating operations and from 
the mixing and storage areas. The EPA estimates that HAP emissions are 
currently about 120 tpy. Most large appliance coating is currently 
applied either by using a spray gun in a spray booth, by dipping the 
substrate in a tank of coating, or by powder coating.
    The Surface Coating of Large Appliances NESHAP specifies numerical 
emission limits for organic HAP emissions from surface coating 
application operations. The organic HAP emission limit for existing 
sources is 0.13 kilogram (kg) organic HAP/liter (1.1 pound/gallon (lb/
gal)) of coating solids and for new or reconstructed sources is 0.022 
kg organic HAP/liter (0.18 lb/gal) of coating solids.
    The Surface Coating of Large Appliances NESHAP provides three 
compliance options for existing sources: (1) Compliant coatings, i.e., 
all coatings have less than or equal to 0.13 kg organic HAP/liter (1.1 
lb/gal) of coating solids; (2) emission rate without add-on controls; 
or (3) emission rate with add-on controls. Facilities using the 
compliant material option or the emission rate without add-on controls 
option are not required to meet any work practice standards, but 
facilities that use add-on controls to demonstrate compliance must 
develop and implement a work practice plan and comply with site-
specific operating limits for the emission capture and control system.
2. What is the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles source category and how does the current NESHAP regulate its 
HAP emissions?
    The EPA promulgated the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles NESHAP on May 29, 2003 (68 FR 32172). The standards 
are codified at 40 CFR part 63, subpart OOOO. The Printing, Coating, 
and Dyeing of Fabrics and Other Textiles industry consists of 
facilities that are engaged in the printing, coating, slashing, dyeing, 
or finishing of fabrics and other textiles. The source category covered 
by this MACT standard currently includes 43 facilities.
    The Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP (40 CFR 63.4371) defines a fabric as any woven, knitted, 
plaited, braided, felted, or non-woven material made of filaments, 
fibers, or yarns, including thread, and further defines textile as any 
one of the following: (1) Staple fibers and filaments suitable for 
conversion to or use as yarns, or for the preparation of woven, knit, 
or nonwoven fabrics; (2) yarns made from natural or manufactured 
fibers; (3) fabrics and other manufactured products made from staple 
fibers and filaments and from yarn; and (4) garments and other articles 
fabricated from fibers, yarns, or fabrics. The NESHAP also defines a 
coating material as an elastomer, polymer, or prepolymer material 
applied as a thin layer to a textile web. This source category is 
further described in the September 12, 2018, RTR proposal. See 83 FR 
46264.
    The primary HAP emitted from printing, coating, and dyeing 
operations are organic HAP and include toluene, phenol, methanol, and 
N,N-dimethylformamide. The majority of organic HAP emissions (greater 
than 95 percent) come from the coating and printing subcategories, with 
the remainder coming from dyeing and finishing. The EPA estimates that 
HAP emissions are currently about 737 tpy.
    The Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP specifies numerical emission limits for organic HAP emissions 
from three subcategories: Printing and coating; dyeing and finishing; 
and slashing. The

[[Page 9594]]

organic HAP emissions limit for existing affected sources is 0.12 kg 
organic HAP/kg (lb/lb) of coating solids applied, and for new or 
reconstructed affected sources the emissions limit is 0.08 kg organic 
HAP/kg (lb/lb) of coating solids applied. Printing or coating-affected 
sources also may demonstrate compliance by achieving at least a 98-
percent HAP reduction for new affected sources or a 97-percent HAP 
reduction for existing sources. Alternatively, new and existing sources 
using a thermal oxidizer may demonstrate compliance by achieving a HAP 
concentration at the oxidizer outlet of no greater than 20 parts per 
million by volume (ppmv) on a dry basis and having an emission capture 
system with 100-percent efficiency.
    For new, reconstructed, or existing dyeing and finishing 
operations, the emissions limit for conducting dyeing operations is 
0.016 kg organic HAP/kg (lb/lb) dyeing materials applied; the emissions 
limit for conducting finishing operations is 0.0003 kg organic HAP/kg 
(lb/lb) finishing materials applied; and the emissions limit for 
conducting both dyeing and finishing operations is 0.016 kg organic 
HAP/kg (lb/lb) dyeing and finishing materials applied.
    For new, reconstructed, or existing slashing operations, the 
slashing materials must contain no organic HAP (each organic HAP that 
is not an Occupational Safety and Health Administration (OSHA)-defined 
carcinogen that is measured to be present at less than 1 percent by 
weight is counted as zero).
    Facilities using the compliant material option or the emission rate 
without add-on controls option are not required to meet any work 
practice standards, but facilities that use add-on controls to 
demonstrate compliance must develop and implement a work practice plan 
and comply with site-specific operating limits for the emission capture 
and control system.
3. What is the Surface Coating of Metal Furniture source category and 
how does the current NESHAP regulate its HAP emissions?
    The EPA promulgated the Surface Coating of Metal Furniture NESHAP 
on May 23, 2003 (68 FR 28606). The standards are codified at 40 CFR 
part 63, subpart RRRR. The Surface Coating of Metal Furniture industry 
consists of facilities that engage, either in part or in whole, in the 
surface coating of metal furniture. The Surface Coating of Metal 
Furniture NESHAP (40 CFR 63.4881) defines metal furniture as furniture 
or components of furniture constructed either entirely or partially 
from metal. The source category covered by this MACT standard currently 
includes 16 facilities. This source category is further described in 
the September 12, 2018, RTR proposal. See 83 FR 46264.
    Most of the organic HAP emissions from metal furniture surface 
coating operations occur from coating application operations and drying 
and curing ovens. Xylene, glycol ethers, ethylbenzene, toluene, and 
cumene account for more than 95 percent of the HAP emitted from the 
source category. The EPA estimates that HAP emissions are currently 
about 145 tpy.
    The Surface Coating of Metal Furniture NESHAP provides existing 
sources three compliance options: (1) Use only compliant coatings, 
i.e., all coatings have less than or equal to 0.10 kg organic HAP/liter 
(0.83 lb/gal) of coating solids used; (2) collectively manage the 
coatings such that the monthly emission rate of organic HAP is less 
than or equal to 0.10 kg organic HAP/liter (0.83 lb/gal) coating solids 
used; or (3) use emission capture systems and control devices to 
achieve an organic HAP emissions rate of less than or equal to 0.10 kg 
organic HAP/liter (0.83 lb/gal) coating solids used.
    Facilities using the compliant material option or the emission rate 
without add-on controls option are not required to meet any work 
practice standards, but facilities that use add-on controls to 
demonstrate compliance must develop and implement a work practice plan 
and comply with site-specific operating limits for the emission capture 
and control system.

C. What changes did we propose for the source categories in our 
September 12, 2018, RTR proposal?

    On September 12, 2018, the EPA published a proposed rule in the 
Federal Register for the Surface Coating of Large Appliances NESHAP; 
the Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP; 
and the Surface Coating of Metal Furniture NESHAP, 40 CFR part 63, 
subpart NNNN, 40 CFR part 63, subpart OOOO, and 40 CFR part 63, subpart 
RRRR, respectively, that took into consideration the RTR analyses.
    We proposed to find that the risks from each of the source 
categories are acceptable, and that additional emission controls for 
each source category are not necessary to provide an ample margin of 
safety.
    We also proposed the following amendments:
     Pursuant to the technology reviews for the Surface Coating 
of Large Appliances source category and the Surface Coating of Metal 
Furniture source category, a requirement that, for each coating 
operation for which coatings are spray applied, high-efficiency spray 
equipment must be used if the source is not using the emission rate 
with add-on control compliance option;
     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 OSHA's 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 EPA guidelines;
     For each source category, IBR of alternative test methods 
and references to updated alternative test methods; and
     Several minor editorial and technical changes in each 
subpart.
    In the same notice, we requested comment on the following, although 
we did not propose actual rule amendments:
     Whether the EPA should change the reporting frequency for 
all reports submitted to the EPA from semi-annual to annual, for all 
three source categories;
     Whether, for all three source categories, additional 
performance testing should be required, with a specific request for 
comment on a requirement to conduct performance testing any time a 
source plans to undertake an operational change that may adversely 
affect compliance with an applicable standard, operating limit, or 
parametric monitoring value;
     Whether the Agency should ban the use of ethylene oxide in 
the Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category under the technology review;

[[Page 9595]]

     Whether the Agency should establish a work practice for 
sources in the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles source category for periods of malfunction when an immediate 
line shutdown may not be feasible due to safety concerns, and concerns 
that an immediate shutdown would result in the unnecessary generation 
of hazardous waste; and
     The relationship between CAA sections 112(d)(6), 
technology review, and CAA section 112(f), residual risk review; 
specifically, the extent to which findings that underlie a CAA section 
112(f) determination should be considered in making any determinations 
under CAA section 112(d)(6).

III. What is included in these final rules?

    This action amends and finalizes the EPA's determinations pursuant 
to the RTR provisions of CAA section 112 for three rules--the Surface 
Coating of Large Appliances; the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles; and the Surface Coating of Metal Furniture. 
This action also finalizes the following changes for each source 
category:
     A requirement for periodic performance testing of capture 
and control devices every 5 years;
     A requirement for electronic submittal of notifications, 
semi-annual reports, and compliance reports (which include performance 
test reports);
     Revising the SSM provisions of each NESHAP;
     Adding the option to conduct 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;
     Removing references to paragraph (d)(4) of OSHA's 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 EPA 
guidelines;
     IBR of alternative test methods and references to updated 
alternative test methods and updated appendices; and
     Several minor technical amendments and clarifications of 
the applicability of the NESHAP and definitions.

A. What are the final rule amendments based on the risk review for the 
Surface Coating of Large Appliances; Printing, Coating, and Dyeing of 
Fabrics and Other Textile; and Surface Coating of Metal Furniture 
source categories?

    This section describes the final amendments to the Surface Coating 
of Large Appliances NESHAP (40 CFR part 63, subpart NNNN); the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP (40 
CFR part 63, subpart OOOO); and the Surface Coating of Metal Furniture 
NESHAP (40 CFR part 63, subpart RRRR) being promulgated pursuant to CAA 
section 112(f). The EPA proposed no changes to these three subparts 
based on the risk reviews conducted pursuant to CAA section 112(f). In 
this action, we are finalizing our proposed determination that 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 
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 review 
for the source categories?

    For 40 CFR part 63, subpart NNNN, 40 CFR part 63, subpart OOOO, and 
40 CFR part 63, subpart RRRR, we are not finalizing any revisions to 
the MACT standards under CAA section 112(d)(6) pursuant to our 
technology reviews.

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

    We are finalizing, as proposed, changes to the Surface Coating of 
Large Appliances; the Printing, Coating, and Dyeing of Fabrics and 
Other Textiles; and the Surface Coating of Metal Furniture source 
categories NESHAP to eliminate the SSM exemption. Consistent with 
Sierra Club v. EPA 551 F. 3d 1019 (D.C. Cir. 2008), the EPA is 
establishing standards in these rules that apply at all times. Table 2 
to Subpart NNNN of Part 63, Table 3 to Subpart OOOO of Part 63, and 
Table 2 to Subpart RRRR of Part 63 (General Provisions applicability 
table) are being revised to change several references related to 
requirements that apply during periods of SSM. We eliminated or revised 
certain recordkeeping and reporting requirements related to the 
eliminated SSM exemption. The EPA also made changes to the rule to 
remove or modify inappropriate, unnecessary, or redundant language in 
the absence of the SSM exemption. We determined that facilities in 
these source categories can meet the applicable emission standards in 
the Surface Coating of Large Appliances; the Printing, Coating, and 
Dyeing of Fabrics and Other Textiles; and the Surface Coating of Metal 
Furniture NESHAP at all times, including periods of startup and 
shutdown. Therefore, the EPA 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 
today are set forth in the proposed rule. See 83 FR 46284 through 
46288, 46295 through 46298, and 46305 through 46308.
    We are finalizing a revision to the performance testing 
requirements at 40 CFR 63.4164, 40 CFR 63.4360, and 40 CFR 63.4963. The 
final performance testing provisions prohibit performance testing 
during startup, shutdown, or malfunction as these conditions are not 
representative of normal operating procedures. The final rules will 
also require that operators maintain records to document that operating 
conditions during the test represent normal operations.

D. What other changes have been made to the 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 and 
operators of facilities in the Surface Coating of Large Appliances; 
Printing, Coating, and Dyeing of Fabrics and Other Textiles; and 
Surface Coating of Metal Furniture 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.
    We are finalizing amendments to 40 CFR 63.4166(b), 40 CFR 
63.4362(b), and

[[Page 9596]]

40 CFR 63.4965(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, for those facilities using the emission rate with add-on 
control compliance option and EPA Method 25A to measure control device 
destruction efficiency. We also are finalizing 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.
    For each subpart, we are finalizing the proposal to remove the 
reference to paragraph (d)(4) of OSHA's Hazard Communication standard 
(29 CFR 1910.1200) and replace with a reference to a new table in each 
subpart (Table 5 to 40 CFR part 63, subpart NNNN, Table 6 to 40 CFR 
part 63, subpart OOOO, and Table 5 to 40 CFR part 63, subpart RRRR) 
that lists the organic HAP that must be included in calculating total 
organic HAP content of a coating material present at 0.1 percent or 
greater by mass. We are finalizing the a provision to include organic 
HAP in these tables if they 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/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. Facilities will be able to conduct 
these performance tests on the same schedule as their title V operating 
permit renewals. If the title V permit already requires performance 
testing, no additional testing will be required.
1. What other changes have been made to the Surface Coating of Large 
Appliances source category NESHAP?
    We are finalizing several miscellaneous technical amendments to 
improve the clarity of the rule requirements:
     Clarifying that a thermocouple is part of the temperature 
sensor referred to in 40 CFR 63.4168(c)(3) for purposes of performing 
periodic calibration and verification checks;
     Renumbering 40 CFR 63.4130(k)(8) and (9) to be 40 CFR 
63.4130(k)(7) and (8) because the current paragraph 40 CFR 63.4130(k) 
is missing a paragraph (k)(7);
     Revising the rule citation ``Sec.  63.4130(k)(9)'' in 40 
CFR 63.4163(e) to be ``Sec.  63.4130(k)(8),'' consistent with the 
proposed renumbering of 40 CFR 63.4130(k)(9) to (k)(8);
     Clarifying that 40 CFR 63.4131(a) applies to all records 
that were submitted as reports electronically via the EPA's CEDRI and 
adding text to the same provision to clarify that the 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; and
     Revising 40 CFR 63.4141(b) and (c) to update ASTM 
International (ASTM) D1475-90 to ASTM D1475-13, including IBR of the 
newer version of the method.
    We are finalizing corrections to several erroneous rule citations:
     Revising one instance in 40 CFR 63.4160(a)(1) and three 
instances in 40 CFR 63.4160(b)(1) that an erroneous rule citation 
``Sec.  63.4183'' is specified. Section 63.4183 does not exist in 40 
CFR part 63, subpart NNNN, and the corrected citation is ``Sec.  
63.4083'';
     Revising one instance in 40 CFR 63.4110(b)(10) of an 
erroneous rule citation ``Sec.  63.4081(d).'' The corrected citation is 
``Sec.  63.4081(e)'';
     Revising one instance in 40 CFR 63.4130(f) and one 
instance in 40 CFR 63.4130(g) of an erroneous rule citation of ``Sec.  
63.4141(a).'' The corrected citation is ``Sec.  63.4141'';
     Revising one instance in 40 CFR 63.4168(c)(2) where an 
erroneous rule citation ``Sec.  63.6167(b)(1) and (2)'' is specified. 
The corrected citation is to ``Sec.  63.4167(b)(1) and (2)'';
     Revising the rule citation for ``Sec.  63.4120(b)'' 
specified in the fourth column of the table entry for ``Sec.  
63.10(d)(2).'' The corrected citation is ``Sec.  63.4120(h)'';
     Revising the rule citation ``Sec.  63.4120(b)'' specified 
in the fourth column of the table entry for ``Sec.  63.10(e)(3).'' The 
corrected citation is ``Sec.  63.4120(g)''; and
     Clarifying that 40 CFR 63.4152(c) requires a statement 
that the source was in compliance with the emission limitations during 
the reporting period applies only if there were no deviations from the 
emission limitations.
    The above clarifications and corrections were proposed in the 
September 12, 2018, RTR proposal. No comments were received during the 
public comment period and these changes are being finalized as 
proposed.
2. What other changes have been made to the Printing, Coating, and 
Dyeing of Fabrics and Other Textiles source category NESHAP?
    We are finalizing the proposal to amend 40 CFR 63.4350(a)(3) and 
(b)(3); and 40 CFR 63.4351(a) and (e) to correct the references to the 
alternative control device outlet organic HAP concentration limit from 
20 parts per million by weight to 20 ppmv.
    In addition, we are finalizing several miscellaneous technical 
amendments to improve the clarity of the rule requirements:
     Clarifying that a thermocouple is part of the temperature 
indicator referred to in 40 CFR 63.4364(c) for purposes of performing 
periodic calibration and verification checks;
     Clarifying that 40 CFR 63.4313(a) applies to all records 
that were submitted as reports electronically via the EPA's CEDRI and 
adding text to the same provision to clarify that the 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;
     Amending a reporting requirement in 40 CFR 63.4342(f) to 
harmonize the requirement with the same reporting requirement in 40 CFR 
63.4311(a)(4) that requires the same statement to be reported if 
``there were no deviations from the emission limitations in Sec. Sec.  
63.4290, 63.4292, and 63.4293'';
     Revising one instance in 40 CFR 63.4311(a)(7)(i)(B) to add 
a reference for an equation that is missing by adding ``6'' to the list 
of equations cited in 40 CFR 63.4311(a)(7)(i)(B) so that the citation 
reads ``Equations 4, 4A, 5, 6, and 7 of Sec.  63.4331'';
     Revising one instance in 40 CFR 63.4340(b)(3) in which an 
erroneous rule citation to ``Sec.  63.4561'' is corrected to ``Sec.  
63.4341''; and
     Correcting Table 3 to 40 CFR part 63, subpart OOOO in the 
fourth column of the table entry for ``Sec.  63.8(g)(1)-(5)'' that 
erroneously refers to ``sections 63.4342 and 63.4352.'' The correct 
reference is ``Sections 63.4363 and 63.4364.''
    The above clarifications and corrections were proposed in the

[[Page 9597]]

September 12, 2018, RTR proposal. No comments were received during the 
public comment period and these changes are being finalized as 
proposed.
3. What other changes have been made to the Surface Coating of Metal 
Furniture source category NESHAP?
    We are finalizing several proposed miscellaneous technical 
amendments to improve the clarity of the rule requirements:
     Clarifying that a thermocouple is part of the temperature 
sensor referred to in 40 CFR 63.4967(c)(3) for purposes of performing 
periodic calibration and verification checks;
     Clarifying that 40 CFR 63.4931(a) applies to all records 
that were submitted as reports electronically via the EPA's CEDRI and 
adding text to the same provision to clarify that the 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;
     Revising the second sentence of 40 CFR 63.4920(a)(4) to 
correct an erroneous reference to ``the emission limitations in Sec.  
63.4890.'' The correct reference is to the applicable emission 
limitations in 40 CFR 63.4890, 63.4892, and 63.489;
     Changing ``emission limitations'' in the first sentence of 
40 CFR 63.4920(a)(4) to ``emission limits'';
     Revising 40 CFR 63.4941(c) to update ASTM D1475-90 to ASTM 
D1475-13, including IBR of the newer version of the method;
     Revising 40 CFR 63.4951(c) to remove repetition with the 
cross-referenced 40 CFR 63.4941(c); and
     Correcting Table 2 to 40 CFR part 63, subpart RRRR in the 
fourth column of the table entry for ``Sec.  63.10(e)(3)'' for an 
erroneous rule citation of ``Sec.  63.4920(b).'' The correct rule 
citation is ``Sec.  63.4920(a).''
    The above clarifications and corrections were proposed in the 
September 12, 2018, RTR proposal. No comments were received during the 
public comment period and these changes are being finalized as 
proposed.

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

    The effective date of all three final rules is March 15, 2019. We 
are finalizing two changes that would impact ongoing compliance 
requirements for each of these three subparts. We are adding a 
requirement that notifications, performance test results, and 
semiannual compliance reports be submitted electronically using the new 
template for each subpart that was included in the docket for each 
proposed rule. We are also changing the requirements for SSM by 
removing the exemption from the requirements to meet the standard 
during SSM periods and by removing the requirement to develop and 
implement an SSM plan. From our assessment of the timeframe needed for 
implementing the entirety of the revised requirements, the EPA proposed 
a period of 180 days to be the most expeditious compliance period 
practicable. No comments were received during the public comment period 
and the 180-day period is being finalized as proposed. Thus, the 
compliance date of the final amendments for all affected sources will 
be September 11, 2019.

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 and operators of 
facilities in the Surface Coating of Large Appliances; the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles; and the Surface 
Coating of Metal Furniture source categories to submit electronic 
copies of certain required performance test reports.
    Data will be collected by direct computer-to-computer electronic 
transfer using EPA-provided software. This EPA-provided software is an 
electronic performance test report tool called the ERT (Electronic 
Reporting Tool). The ERT will generate an electronic report package 
which will be submitted to CEDRI, and then archived to the EPA's CDX. A 
description of the ERT and instructions for using ERT can be found at 
https://www3.epa.gov/ttn/chief/ert/index.html. 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. Through this 
approach, industry will save time in the performance test submittal 
process. Additionally, this rulemaking will benefit industry by 
reducing recordkeeping costs, as the performance test reports that are 
submitted to the EPA using CEDRI are no longer required to be kept in 
hard copy.
    State, local, and tribal agencies may benefit from a more 
streamlined and accurate review of performance test data that will 
become available to the public through WebFIRE. Having such data 
publicly available enhances transparency and accountability. For a more 
thorough discussion of electronic reporting of performance tests using 
direct computer-to-computer electronic transfer and using EPA-provided 
software, see the discussion in the preamble of the proposal.
    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 three surface coating source categories?

A. Residual Risk Reviews

1. What did we propose pursuant to CAA section 112(f)?
a. Surface Coating of Large Appliances (40 CFR part 63, Subpart NNNN) 
Source Category
    Pursuant to CAA section 112(f), 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 September 12, 2018, proposed rule for 40 CFR part 63, 
subpart NNNN (83 FR 46262). 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 Large Appliances Source 
Category in Support of the May 2018 Risk and Technology Review Proposed 
Rule,'' available in the docket for this rulemaking.

\1\ The target organ-specific hazard index (TOSHI) is the sum of the chronic noncancer hazard quotients (HQ) values 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 = hazard
  quotient recommended 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) 
could be up to 0.9-in-1 million, the maximum chronic noncancer TOSHI 
value based on actual emissions could be up to 0.07, and the maximum 
screening acute noncancer HQ value (off-facility site) could be up to 2 
(driven by glycol ethers). At proposal, the total annual cancer 
incidence (national) from these facilities based on actual emission 
levels was estimated to be 0.0001 excess cancer cases per year, or one 
case in every 10,000 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) could be up to 1-in-1 million, and the maximum 
chronic noncancer TOSHI value based on allowable emissions could be up 
to 0.08. At proposal, the total annual cancer incidence (national) from 
these facilities based on allowable emission levels was estimated to be 
0.0002 excess cancer cases per year, or one case in every 5,000 years.
    The maximum whole-facility cancer maximum individual risk (MIR) was 
determined to be 6-in-1 million at proposal, driven by chromium (VI) 
compounds from a cleaning/pretreatment operation. At proposal, the 
total estimated cancer incidence from whole facility emissions was 
determined to be 0.0002 excess cancer cases per year, or one excess 
case in every 5,000 years. Approximately 600 people were estimated to 
have cancer risks above 1-in-1 million from exposure to HAP emitted 
from both MACT and non-MACT sources at the 10 facilities in this source 
category. The maximum facility-wide TOSHI for the source category was 
estimated to be 0.2, driven by emissions of methylene diphenyl 
diisocyanate from foam produced as part of plastic products 
manufacturing.
    There are no persistent and bioaccumulative HAP (PB HAP) emitted by 
facilities in this source category. Therefore, we did not estimate any 
human health multi-pathway risks from this source category. Two 
environmental HAP are emitted by sources within this source category: 
Hydrogen chloride (HCl) and hydrogen flouride (HF). Therefore, at 
proposal we conducted a screening-level evaluation of the potential 
adverse environmental risks associated with emissions of HCl and HF. 
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 Large 
Appliances source category are acceptable (section IV.A.2.a of proposal 
preamble, 83 FR 46279, September 12, 2018).
    We then considered whether 40 CFR part 63, subpart NNNN provides an 
ample margin of safety to protect public health and prevents, taking 
into consideration costs, energy, safety, and other relevant factors, 
an adverse environmental effect. 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.
    As discussed further in section III.B. of this preamble, the only 
development identified in the technology review was the use of high-
efficiency spray equipment. We estimated no changes in costs or 
emissions would occur due to switching to high-efficiency application 
methods for this source category, because we expected that large 
appliance surface coating facilities already are using high-efficiency 
coating application methods due to state volatile organic compound 
(VOC) rules and the economic incentives of using more efficient 
application methods. Because quantifiable reductions in risk are 
unlikely, we proposed that additional emissions controls for this 
source category are not necessary to provide an ample margin of safety 
(section IV.A.2.b. of proposal preamble, 83 FR 46279, September 12, 
2018).
b. Printing, Coating, and Dyeing of Fabrics and Other Textiles (40 CFR 
Part 63, Subpart OOOO) Source Category
    Pursuant to CAA section 112(f), 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 September 12, 2018, proposed rule for 40 CFR part 63, 
subpart OOOO (83 FR 46262). 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 Printing, Coating, and Dyeing of Fabrics and 
Other Textiles Source Category in Support of the May 2018 Risk and 
Technology Review Proposed Rule,'' available in the docket for this 
rulemaking.

\1\ The target organ-specific hazard index (TOSHI) is the sum of the chronic noncancer hazard quotient (HQ) values 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 = hazard
  quotient recommended exposure level).

    The results of the proposal inhalation risk modeling using actual 
emissions data, as shown in Table 3 of this preamble, indicate that the 
maximum individual cancer risk based on actual emissions (lifetime) 
could be up to 9-in-1 million (driven by ethylene oxide), the maximum 
chronic noncancer TOSHI value based on actual emissions could be up to 
0.3, and the maximum screening acute noncancer HQ value (off-facility 
site) could be up to 0.6. At proposal, the total annual cancer 
incidence (national) from these facilities based on actual emission 
levels was estimated to be 0.002 excess cancer cases per year, or one 
case in every 500 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) could be up to 10-in-1 million (driven by ethylene 
oxide), the maximum chronic noncancer TOSHI value based on allowable 
emissions could be up to 0.3. At proposal, the total annual cancer 
incidence (national) from these facilities based on allowable emission 
levels was estimated to be 0.002 excess cancer cases per year, or one 
case in every 500 years.
    The maximum facility-wide cancer MIR was 9-in-1 million at 
proposal, driven by ethylene oxide from fabric finishing. The results 
of our facility-wide assessment at proposal indicated that 12 
facilities have a facility-wide cancer MIR greater than or equal to 1-
in-1 million. At proposal the total estimated cancer incidence from 
whole facility emissions was determined to be 0.003 excess cancer cases 
per year, or one excess case in every 330 years. Approximately 12,200 
people were estimated to have cancer risks above 1-in-1 million from 
exposure to HAP emitted from both MACT and non-MACT sources collocated 
at the 43 facilities in this source category. The maximum facility-wide 
TOSHI for the source category was estimated to be 0.3, driven by 
emissions of trichloroethylene from adhesive application.
    There are no PB-HAP emitted by facilities in this source category. 
Therefore, we did not estimate any human health multi-pathway risks 
from this source category. Environmental HAP are not emitted by sources 
within this source category; therefore, 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 Printing, Coating, and Dyeing 
of Fabrics and Other Textiles source category are acceptable (section 
IV.B.2.a of proposal preamble, 83 FR 46292, September 12, 2018).
    We then considered whether 40 CFR part 63, subpart OOOO provides an 
ample margin of safety to protect public health and prevents, taking 
into consideration costs, energy, safety, and other relevant factors, 
an adverse environmental effect. 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, we did not identify any developments in add-on 
control technologies, other equipment or work practices and procedures 
since the promulgation of the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles NESHAP. We note, however, that the only facility 
that previously reported ethylene oxide emissions no longer emits this 
HAP as a result of a process change. 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, 83 FR 46293, September 12, 2018). However, we 
solicited comment on whether the Agency should ban the use of ethylene 
oxide in this source category under the technology review (section VI 
of proposal preamble, 83 FR 46313, September 12, 2018). Our response to 
these comments and rationale for our final decision are found in 
section IV.B of this preamble.
c. Surface Coating of Metal Furniture (40 CFR Part 63, Subpart RRRR) 
Source Category
    Pursuant to CAA section 112(f), 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 September 12, 2018, proposed rule for 40 CFR part 63, 
subpart RRRR (83 FR 46262). 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 Metal Furniture Source 
Category in Support of the May 2018 Risk and Technology Review Proposed 
Rule,'' available in the docket for this rulemaking.

\1\ The TOSHI is the sum of the chronic noncancer HQ values 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 = hazard
  quotient recommended 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) 
could be up to 7-in-1 million (driven by ethyl benzene), the maximum 
chronic noncancer TOSHI value based on actual emissions could be up to 
0.2, and the maximum screening acute noncancer HQ value (off-facility 
site) could be up to 2 (driven by glycol ethers). At proposal, the 
total annual cancer incidence (national) from these facilities based on 
actual emission levels was estimated to be 0.0004 excess cancer cases 
per year, or one case in every 2,500 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) could be up to 10-in-1 million (driven by ethyl 
benzene), the maximum chronic noncancer TOSHI value based on allowable 
emissions could be up to 0.3. At proposal, the total annual cancer 
incidence (national) from these facilities based on allowable emission 
levels was estimated to be 0.0008 excess cancer cases per year, or one 
case in every 1,250 years.
    The maximum facility-wide cancer MIR was 7-in-1 million at 
proposal, driven by ethyl benzene. Four facilities had a facility-wide 
cancer MIR greater than or equal to 1-in-1 million. At proposal, the 
total cancer incidence from whole facility emissions was estimated to 
be 0.0005 excess cancer cases per year, or one excess case in every 
2,000 years. Approximately 2,200 people were estimated to have cancer 
risks above 1-in-1 million from exposure to HAP emitted from both MACT 
and non-MACT sources at the 16 facilities in this source category. The 
maximum facility-wide TOSHI for the source category was estimated to be 
0.1.
    There are no PB-HAP emitted by facilities in this source category. 
Therefore, we did not estimate any human health multi-pathway risks 
from this source category. Environmental HAP are not emitted by sources 
within this source category; therefore, 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 Metal 
Furniture source category are acceptable (section IV.C.2.a of proposal 
preamble, 83 FR 46301, September 12, 2018).
    We then considered whether 40 CFR part 63, subpart RRRR provides an 
ample margin of safety to protect public health and prevents, taking 
into consideration costs, energy, safety, and other relevant factors, 
an adverse environmental effect. 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.
    As discussed in detail in section III.B of this preamble, the only 
development identified in the technology review was the use of high-
efficiency spray equipment. We estimated no changes in costs or 
emissions reductions would occur due to switching to high-efficiency 
application methods for this source category because we expected that 
metal furniture surface coating facilities were already using high-
efficiency coating application methods due to state VOC rules and the 
economic incentives of using these more efficient application methods. 
Because quantifiable reductions in risk are unlikely, we proposed that 
additional emissions controls for this source category were not 
necessary to provide an ample margin of safety (section IV.C.2.b. of 
proposal preamble, 83 FR 46302, September 12, 2018).
2. How did the risk review change?
    We have not changed any aspect of the risk assessment since the 
September 2018 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 review and our determination 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 were necessary. The comments and our specific responses can be 
found in the document, ``Summary of Public Comments and Responses for 
the Risk and Technology Reviews for Surface Coating of Large 
Appliances; Printing, Coating, and Dyeing of Fabrics and Other 
Textiles; and Surface Coating of Metal Furniture,'' available in the 
dockets for these actions (Docket ID Nos. EPA-HQ-OAR-2017-0668, EPA-HQ-
OAR-2017-0669, and EPA-HQ-OAR-2017-0670).

[[Page 9601]]

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 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 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, we determined that the risks from each of these three 
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 readopting the 
existing standards under CAA section 112(f)(2).

B. Technology Reviews

1. What did we propose pursuant to CAA section 112(d)(6)?
    The Surface Coating of Large Appliances NESHAP and the Surface 
Coating of Metal Furniture NESHAP do not contain any standards 
specifying the type of spray application equipment that must be used 
when coatings are spray applied. Sources subject to the Printing, 
Coating, and Dyeing of Fabric and Other Textiles NESHAP do not spray 
apply coatings. However, many facilities complying with these NESHAP 
also are required by state VOC regulations to use high-efficiency spray 
guns for coatings that are spray applied. We expected that other large 
appliance surface coating and metal furniture surface coating 
facilities in other states are also using high-efficiency application 
equipment for spray-applied coatings to reduce coating and spray booth 
filter consumption and to reduce the amount of solid waste generated in 
the form of used spray booth filters. Although we expected that 
switching to high-efficiency spray application equipment would have 
lower costs at facilities not already using it, we are uncertain of 
other factors that facilities may need to consider if choosing to 
switch to high-efficiency application equipment.
    Based on these findings, we proposed to revise the Surface Coating 
of Large Appliances NESHAP and the Surface Coating of Metal Furniture 
NESHAP for coating application operations pursuant to CAA section 
112(d)(6) to require that, for each coating operation for which 
coatings are spray applied, high-efficiency spray equipment must be 
used if the source is not using the emission rate with add-on control 
compliance option. Specifically, all spray-applied coating operations, 
where the source is not using the emission rate with add-on control 
compliance option, would have been required to achieve transfer 
efficiency equivalent to or better than 65 percent. At proposal four 
types of high-efficiency spray equipment technologies were identified 
that the EPA believed could achieve transfer efficiency equivalent to 
or better than 65 percent, including high volume, low pressure (HVLP) 
spray equipment; electrostatic application; airless spray equipment; 
and air-assisted airless spray equipment. Alternative spray equipment 
technologies would have had to provide documentation demonstrating at 
least 65-percent transfer efficiency. Spray application equipment 
sources using alternative spray application equipment technologies 
other than the four listed would have had to follow procedures in the 
California South Coast Air Quality Management District's, ``Spray 
Equipment Transfer Efficiency Test Procedure for Equipment User, May 
24, 1989,'' to demonstrate that their spray application equipment is 
capable of achieving transfer efficiency equivalent to, or better than, 
65 percent. Equivalency documentation would have been certified by 
manufacturers of the spray equipment, on behalf of facilities using 
spray-applied coatings, by following the aforementioned procedure in 
conjunction with California South Coast Air Quality Management 
District's, ``Guidelines for Demonstrating Equivalency with District 
Approved Transfer Efficient Spray Guns, September 26, 2002.'' We 
proposed that all spray equipment used for spray-applied coating 
operations be required to be operated according to company procedures, 
local specified operating procedures, or the manufacturer's 
specifications, whichever achieved 65-percent transfer efficiency. 
Further, we proposed related definitions for ``airless and air-assisted 
airless spray,'' ``electrostatic application,'' ``high-volume, low-
pressure (HVLP) spray equipment,'' ``spray-applied coating 
operations,'' ``and transfer efficiency.''
    For the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
source category, we identified one potential development in technology: 
A process change that eliminated the use of ethylene oxide at one 
facility. In our residual risk analysis for this source category, we 
estimated the maximum facility-wide cancer MIR to be 9-in-1 million, 
driven by ethylene oxide emissions from fabric finishing at one 
facility. During a site visit to the facility that reported ethylene 
oxide emissions in the National Emission Inventory, we learned that the 
ethylene oxide emissions were overstated by the facility. The facility 
confirmed that it no longer uses the ethylene oxide-containing material 
due to cost. We noted this was the only facility that reported ethylene 
oxide emissions, and we concluded that ethylene oxide-containing 
materials are no longer used in the industry, based on our information. 
We solicited comment on whether the Agency should ban the use of 
ethylene oxide in this source category under the technology review.
    We also solicited comment on the relationship between the CAA 
section 112(d)(6) technology review and the CAA section 112(f) risk 
review. We solicited comment on whether revisions to the NESHAP are 
``necessary,'' as the term is used in CAA section 112(d)(6), in 
situations where the EPA has determined that CAA section 112(d) 
standards evaluated pursuant to CAA section 112(f) provide an ample 
margin of safety to protect public health and prevent an adverse 
environmental effect. In other words, we solicited comment on whether 
it is ``necessary'' to revise the standards based on developments in 
technologies, practices, or processes under CAA section 112(d)(6) if 
remaining risks associated with air emissions from a source category 
have already been reduced to levels that provide an ample margin of 
safety under CAA section 112(f). See CAA section 112(d)(6) (``The 
Administrator shall review, and revise as necessary . . .''). We also 
solicited comment on whether further revisions under CAA section 
112(d)(6) would be necessary if the CAA section 112(f) ample margin of 
safety analysis shows lifetime excess cancer risks to the individual 
most exposed to emissions from a source in the category is less than 1-
in-1 million or if other, either higher

[[Page 9602]]

or lower, cancer risk levels would be appropriate to consider if they 
assured an ample margin of safety.
2. How did the technology review change?
    We are not finalizing the proposal to require the use of high-
efficiency application equipment for spray-applied coatings in the 
Surface Coating of Large Appliances NESHAP and the Surface Coating of 
Metal Furniture NESHAP.
    We solicited comment on the potential process change that 
eliminated the use of ethylene oxide at one facility, but did not 
propose this requirement for the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles source category. Based on the comments we 
received, we are making no changes as a result of the technology review 
to the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP.
3. What key comments did we receive on the technology reviews, and what 
are our responses?
    Comment: One commenter supported the EPA's proposal to require 
Large Appliances and Metal Furniture facilities to use high-efficiency 
spray equipment as a technology development under CAA section 
112(d)(6). However, the commenter disagreed with the EPA's conclusion 
that all or most sources are likely using high-efficiency spray 
equipment. They argued that the EPA provided no evidence there would be 
no emission reduction, and argued that the proposed requirement would 
prevent emission increases in the future if economic incentives or 
state rules currently encouraging the use of high-efficiency spray 
equipment change.
    Another commenter objected to the proposed language that all 
``spray application equipment must be operated according to company 
procedures, local specified operating procedures, and/or the 
manufacturer's specifications, whichever is most stringent, at all 
times.'' The commenter argued that it was unclear how facilities would 
ensure the equipment is operated according to the more stringent 
approach so as to avoid having a potential permit deviation/violation 
even though they may still be complying with the underlying numerical 
emission standard.
    Response: The EPA has determined not to finalize the proposed 
requirement for all sources to use high-efficiency spray application 
technology that has a transfer efficiency of at least 65 percent 
because we believe our assumptions at proposal may not be appropriate 
for all coating-related processes in the metal furniture and large 
appliances source categories. We do not have sufficient data at this 
time to determine if the high-efficiency spray application technology 
requirement is reasonable from a technological perspective.
    At proposal, a critical assumption we made was that the four high-
efficiency spray equipment technologies required in the proposed 
rulemaking (HVLP, electrostatic application, airless and air assisted 
airless spray equipment) would achieve at least 65-percent transfer 
efficiency when used by all facilities in the Surface Coating of Metal 
Furniture and Surface Coating of Large Appliances source categories. 
New information, however, leads us to conclude that the transfer 
efficiency of the proposed high-efficiency spray application 
technologies may be less than 65 percent, as it is dependent on 
parameters such as part size, part shape, distance of the spray gun 
from the parts, atomizing air pressure, fluid pressure, painting 
technique, type of coating, viscosity of the coating, and more. 
Generally, the smaller and narrower the part being coated, the lower 
the transfer efficiency. Conversely, the larger and wider the part 
being painted, the higher the transfer efficiency. Therefore, transfer 
efficiency varies greatly source category-by-source category. In both 
the Surface Coating of Metal Furniture and Surface Coating of Large 
Appliances source categories, parts are of various shapes and sizes; 
therefore, transfer efficiency using high-efficiency spray application 
technologies could be lower than the 65-percent transfer efficiency 
requirement in the proposed rule, depending on the size and shape of 
the parts being coated.
    Additionally, we did not receive any data that would allow us to 
determine the actual average transfer efficiency of the spray 
application technologies we identified in the proposed rule. In light 
of this uncertainty, we conclude it would be difficult, if not 
impossible, to determine at this time the appropriate high-efficiency 
spray application technologies or transfer efficiency to require. 
Absent more data and information, we are not able to adequately 
estimate the technical feasibility of the proposed 65-percent transfer 
efficiency requirement for the Surface Coating of Metal Furniture and 
Surface Coating of Large Appliances source categories.
    The situation for the Surface Coating of Metal Furniture and 
Surface Coating of Large Appliances source categories is different from 
other rules where we have required use of high-efficiency spray 
application. For example, the high-efficiency spray application 
requirements in the Aerospace Manufacturing and Rework Operations 
NESHAP were based on available data that allowed us to estimate the 
technological feasibility of the requirements. Absent similar data for 
the Surface Coating of Metal Furniture and Surface Coating of Large 
Appliances source categories, we believe it is not reasonable to 
require the use of the high-efficiency spray application technologies 
proposed pursuant to CAA section 112(d)(6) at this time. The EPA, in 
the future, may be able to determine the technological capabilities of 
high-efficiency spray application equipment for the Surface Coating of 
Metal Furniture and Surface Coating of Large Appliances source 
categories and revisit the need to require such spray application 
equipment when we have sufficient data and information.
    Finally, as noted in the proposed rule, we believe that most, if 
not all, sources in the Surface Coating of Metal Furniture and Surface 
Coating of Large Appliances source categories are already using the 
types of spray application technologies in the proposed rule pursuant 
to state requirements. We believe that sources will continue to use 
these technologies, even if it is not required in this final rule, 
because of the lower coating consumption and waste disposal costs. 
Nothing in the record supports the comments that states may remove 
these existing spray application technology requirements from current 
regulations. We do not expect sources to change from high-efficiency 
spray technology to lower-efficiency spray equipment, even if state 
requirements changed, unless there was a specific application that did 
not work with high-efficiency spray technology. In those cases, the 
limits on the HAP content of coatings would still apply. We do not 
think it is reasonable to assume sources would choose higher the 
coating and waste disposal costs associated with non-high-efficiency 
spray technology and incur the costs to switch back to non-high-
efficiency spray technology, even if state requirements were removed.
    For all these reasons, we are not finalizing the proposed 
requirement for sources in the Surface Coating of Metal Furniture and 
Surface Coating of Large Appliances source categories to use high-
efficiency spray application equipment.
    Comment: One commenter argued that the EPA should revise the 
Coating, Printing, and Dyeing of Fabric and Other Textiles NESHAP to 
ban the use of ethylene oxide. The commenter argued that failing to ban 
the use of ethylene oxide would allow facilities to

[[Page 9603]]

begin using and emitting this chemical in the future.
    Two commenters argued that they saw no justification or rationale 
to support a ban on the use of ethylene oxide in the Printing, Coating, 
and Dyeing of Fabrics and Other Textiles source category because the 
decision by one company to stop using materials containing ethylene 
oxide based on cost did not represent a development in new control 
technologies, processes, or practices that could be deemed applicable 
and achievable by the rest of the source category. One of the 
commenters argued that, unlike technology changes where efficiency 
gains, emissions reductions, and similar advances are not easily 
reversed, market forces frequently change the business justification 
for and against using particular products.
    The two commenters argued that the record reflects only a decision 
by one company based on a set of factors that may be applicable to only 
that one company and does not provide the statement of basis and 
purpose required by CAA section 307(d)(3). The commenters argued that 
additional information and data would be needed on potential costs and 
emissions reductions and stated that the EPA has not shown whether 
similar reductions are achievable across the source category. They 
argued that this information would need to be available for public 
review and comment. Otherwise, the EPA's proposal would be arbitrary 
and capricious.
    Response: We received no additional information from other 
facilities in the Printing, Coating, and Dyeing of Fabric and Other 
Textiles source category on whether they use materials containing 
ethylene oxide. In addition, we cannot determine whether one facility's 
decision to stop using the material containing ethylene oxide as a cost 
savings measure demonstrates that all applications of ethylene oxide 
should be foreclosed as a development in technology. If sources in this 
category were to later determine that materials with ethylene oxide are 
necessary for a particular application, the sources would still be 
required to comply with the NESHAP limits on the HAP content of 
materials or HAP emissions for sources using add-on controls. 
Therefore, total HAP emissions are unlikely to increase even if sources 
were to start using ethylene oxide containing materials. Under these 
circumstances, we have determined it is not reasonable to conclude that 
ethylene oxide containing coatings should be prohibited for use by all 
sources in the category as an advancement in technology. Finally, we 
cannot determine whether finalizing a ban on the use of materials 
containing ethylene oxide would reduce HAP from the source category or 
otherwise achieve any environmental or risk reduction benefits. For 
these reasons, we are not finalizing a ban on the use of materials 
containing ethylene oxide.
    Comment: We received several substantive and extensive comments in 
response to our request for comments on the relationship between the 
technology review conducted under CAA section 112(d)(6) and the risk 
analysis under CAA section 112(f)(2) and whether it is necessary for 
the EPA to amend rules based on CAA section 112(d) to reflect the 
results of the CAA section 112(d)(6) technology review if the results 
of the risk analysis under CAA section 112(f)(2) show that the current 
rule provides an ample margin of safety and no adverse environmental 
effect. One commenter argued that the EPA must complete the technology 
review and propose standards based on the findings of that review, 
regardless of the results of the risk analysis. Other commenters argued 
that the results of the risk analysis should be considered in the 
``necessity'' determination that should be completed in the process of 
deciding whether to amend a subpart as a result of the technology 
review.
    Response: The EPA is not taking final action on the proposed 
interpretation discussed in this comment. Instead, the EPA has 
determined for the reasons described in this notice not to implement 
the proposed amendments to 40 CFR part 63, subparts NNNN, OOOO, or RRRR 
based on our technology review. As we are not relying on the proposed 
interpretation in our final action, we are not addressing the comments 
we received regarding the relationship between the technology review 
conducted under CAA section 112(d)(6) and the risk analysis under CAA 
section 112(f)(2).
4. What is the rationale for our final approach for the technology 
reviews?
    As noted above, we are not finalizing the proposed requirement to 
use high-efficiency spray application equipment with a 65-percent or 
better transfer efficiency. We received no information in response to 
our request for comment on whether any facilities in this source 
category do not currently use high-efficiency spray application 
methods, so it is unclear whether the proposed requirement is 
achievable for all sources in the category. We also received 
information indicating that the four types of high-efficiency spray 
application equipment described in our proposed rule do not always 
achieve the 65-percent transfer efficiency that we proposed to require 
for high-efficiency spray equipment.
    We are not including in the final rule amendments for the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles NESHAP any 
requirements to ban the use of ethylene oxide in this source category. 
We received no additional information from other facilities on whether 
they use materials containing ethylene oxide, so we cannot determine 
whether a ban would achieve any environmental or risk reduction 
benefits.

C. Ongoing Emissions Compliance Demonstrations

1. What did we propose?
    The EPA requested comment for all three source categories on 
whether additional performance testing should be required for any 
source using the add-on control option based on information from 
pollution control manufacturers indicating that periodic performance 
tests are necessary to ensure HAP removal efficiency for the controls 
is maintained over time. See Proposed Rule, 83 FR 46289. We 
specifically requested comment on whether we should require performance 
testing for a source that is planning to undertake an operational 
change that may adversely affect compliance with an applicable 
standard, operating limit, or parametric monitoring value. Any such 
requirement would have included provisions to allow a source to make 
the change, but it would have limited the change to a specific time 
before a test is required. We anticipated that a reasonable time limit 
under the new operations change would be approximately 30 days to allow 
adequate time for testing and developing a test report. The source 
would submit temperature and flow rate data during the test to 
establish new operating parameters, including the time a source would 
be allowed to operate under the new parameters before the test is 
performed, and what would constitute an operational change requiring 
testing.
    This approach on which we requested comment could have also allowed 
an exception from periodic testing for facilities using instruments to 
continuously measure actual emissions, such as continuous emission 
monitoring systems (CEMS). Use of CEMS to demonstrate compliance would 
obviate the need for periodic oxidizer testing.

[[Page 9604]]

2. What changed since proposal?
    In the final rule amendments for each subpart, the EPA is requiring 
performance testing of control devices at least every 5 years for 
facilities complying with the emission rate with add-on controls 
compliance option. The EPA solicited comment on the need for additional 
performance testing in the proposed rule (see sections IV.A.4.d, 
IV.B.4.d, and IV.C.4.d of the Surface Coating of Large Appliances; 
Printing, Coating, and Dyeing of Fabrics and Other Textiles; and 
Surface Coating of Metal Furniture Residual Risk and Technology 
Reviews, 83 FR 46289, 46299, and 46309, September 12, 2018).
3. What key comments did we receive and what are our responses?
    Comment: One commenter did not support the requirement to complete 
additional add-on control performance testing after operational changes 
that may adversely affect compliance because the EPA did not define the 
operational changes that would trigger the need for performance 
testing. The commenter argued that the EPA did not define the 
anticipated costs, burdens, and benefits associated with this testing. 
The commenter also argued that the suggested 30-day period for testing 
and development of a test report is too short. The commenter 
recommended a period of at least 180 days to allow time to hire a 
testing contractor, to achieve stable (representative) operating 
conditions before the test, and to allow time for the contractor to 
prepare the report.
    Another commenter supported the testing requirement after a process 
change that could affect compliance with an emission limit and noted 
that it was a common feature of MACT rules. The commenter suggested 
that examples of a process change could include venting additional 
equipment to the control device, an increase in line speeds, an 
increase in coating materials used, or use of new coating materials. 
However, the commenter also suggested that the 30-day timeframe to 
perform a test after a process change does not seem adequate to allow a 
facility time to schedule an outside contractor to perform the required 
testing, test report preparation, review by responsible official, and 
submission of results. The commenter recommended a 60-day or 90-day 
timeframe as more appropriate.
    Response: The EPA is not finalizing a requirement to require add-on 
control performance testing after operational changes that may 
adversely affect compliance. The EPA acknowledges the difficultly in 
defining operational changes for each source category that would 
trigger the need for performance testing, as the EPA proposed. However, 
as described in the preamble to the proposed rules, the EPA recognizes 
the need for periodic performance testing after the initial performance 
test to measure the organic HAP destruction or removal efficiency of 
the add-on control device, or to measure the control device outlet 
concentration of organic HAP. As stated in the proposed rule, pollution 
control manufacturers maintain that additional performance testing is 
needed to ensure the control devices are operating properly. Continuous 
compliance with the standards when a facility is using the emission 
rate with add-on control or the control device outlet concentration 
compliance options that are included in each of these three subparts 
depends on the proper functioning of the control device.
    Periodic performance tests require the measurement of the control 
devices' actual destruction efficiency or the actual outlet 
concentration of organic HAP, depending on the compliance option 
chosen, in order to reaffirm or reestablish the control devices' 
operating limits. Periodic performance tests help identify potential 
degradation of the add-on control device over time and ensure the 
control device remains effective, reducing the potential for acute 
emissions episodes or non-compliance. As stated in the proposed rule, 
many facilities using add-on controls to demonstrate compliance with 
the NESHAP emission limits are currently required to conduct 
performance tests as a condition for renewing their title V operating 
permit, which is required every 5 years. Also, specifying a specific 
performance test interval addresses the uncertainty of when tests would 
be required was raised by the commenters.
    Therefore, the EPA is including in the final rule for each subpart 
a requirement that each facility using the emission rate with add-on 
control compliance option or the control device outlet concentration 
compliance option must complete a performance test of the add-on 
control device no less frequently than every 5 years. This approach 
will balance the need to ensure ongoing compliance against providing 
objective criteria for when performance testing must be completed.
    The periodic testing requirement is being added to each subpart but 
is not estimated to impose any costs on the Surface Coating of Large 
Appliances or Surface Coating of Metal Furniture sources categories. No 
facilities in the Surface Coating of Metal Furniture source category 
are known to be using the emission rate with add-on controls compliance 
option. One facility in the Surface Coating of Large Appliances source 
category is using the emission rate with the add-on controls compliance 
option, but already is required to conduct performance testing every 5 
years as a condition of renewing their title V operating permit. In the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category, we have identified 13 facilities using 18 control devices 
that are not currently required to perform testing as a condition of 
renewing their title V operating permits. We estimate that performance 
testing will cost approximately $19,000 per control device once every 5 
years. The annualized cost will be about $4,400 per control device.
    One environmental benefit of periodic performance testing is 
expected to be in the form of reduced excess emissions from sources 
using add-on controls, even though facilities are required to be in 
compliance at all times, and the overall costs and benefits of a NESHAP 
are calculated based on the assumption that facilities are in 
compliance. However, this benefit cannot be quantified because our data 
are not sufficient to estimate the frequency of sources using add-on 
control devices failing to meet the emission standards, and the 
magnitude of the excess emissions. If, for example, the standard has a 
requirement for 98-percent control (e.g., for new or reconstructed 
coating and printing affected sources under 40 CFR part 63, subpart 
OOOO), and the device is achieving only 96-percent, emissions are twice 
what they would be if the device was meeting the standard. This 
potential for significant increases in HAP from poor performing 
controls further supports the requirement to conduct periodic testing 
every 5 years.
4. What is the rational for our final approach?
    For the reasons explained in the preamble to the proposed rules (83 
FR 46262, September 12, 2018) and in the comment responses above in 
section IV.C.3 of this preamble, we are finalizing requirements in each 
of these three subparts to require add-on control performance testing 
no less frequently than once every 5 years.

D. Work Practice During Periods of Malfunction

1. What did we propose?
    The EPA requested comment on the need to establish a standard 
during periods of malfunction of a control device or a capture system 
that is used to meet the emission limits for the

[[Page 9605]]

Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category and asked for specific information to support such a standard. 
We solicited information from industry on best practices and the best 
level of emission control during malfunction events for the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category. We 
solicited information on the potential cost savings associated with 
these practices. We solicited specific supporting data on organic HAP 
emissions during malfunction events for this category, including the 
cause of malfunction, the frequency of malfunction, duration of 
malfunction, and the estimate of organic HAP emitted during each 
malfunction. We also asked specifically for comment on the use of CEMS 
by facilities in this source category as a method to better quantify 
organic HAP emissions during malfunctions and normal operation. We also 
requested comment on two alternative work practices: (1) During a 
malfunction, the facility must discontinue the coating operation, but 
can continue the oven curing of any coating materials already applied 
onto the web without the control device for the period of the 
malfunction so long as it continues to meet the emission limits for the 
current compliance period; or (2) during a malfunction, the facility 
could initiate repairs immediately and complete them as expeditiously 
as possible, without ceasing operations, until it becomes apparent that 
the repairs will not be completed before exceeding the 12-month rolling 
average compliance limit. Neither alternative provided an opportunity 
to exceed the emissions limit. (See section IV.B.4.b of the Surface 
Coating of Large Appliances; Printing, Coating, and Dyeing of Fabrics 
and Other Textiles; and Surface Coating of Metal Furniture Residual 
Risk and Technology Reviews, 83 FR 46295, September 12, 2018).
2. What changed since proposal?
    The EPA is not providing a work practice standard for periods of 
malfunction of a control device or a capture system for the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category in 
the final rule amendments.
3. What key comments did we receive and what are our responses?
    Comment: One commenter supported the work practice standard that 
would apply during malfunctions of any control device or capture system 
used by a web coating line, described as alternative 1 in the proposal 
preamble, and requested that the EPA develop a malfunction alternative 
that balances the generation of waste (from inadequate drying; cured 
coatings in lines and guns; and generation of waste coatings) and/or 
worker safety with exceeding emission limits. However, the commenter 
did not provide any supporting data or information in response to the 
EPA's specific solicitation in the proposal preamble.
    Another commenter did not support a work practice standard and 
noted that it was unlawful to add a malfunction exemption or set a so-
called malfunction-based standard for any source category, including 
the Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category, because, among other arguments, emission standards must be 
``continuous.'' A complete summary of the comments received on the 
EPA's proposal is included in the docket for this rulemaking.
    Response: The EPA is not finalizing a separate standard for periods 
of malfunction, although the EPA may establish a standard for periods 
of malfunction if the available information supports a separate 
standard in the future. In this case, we requested comment and 
information to support the development of a work practice standard 
during periods of malfunction, but we did not receive sufficient 
information, including additional quantitative emissions data, on which 
to base a standard for periods of malfunction. Absent sufficient 
information, it is not reasonable at this time to establish a work 
practice standard for this source category. We will continue to review 
this issue to determine if any new data become available in the future.
4. What is the rational for our final approach?
    We are not finalizing a separate standard for periods of 
malfunction for the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles source category, because we did not receive sufficient 
information on which to base a standard for periods of malfunction.

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

A. What are the affected facilities?

    We estimate that the 10 major sources subject to the Surface 
Coating of Large Appliances NESHAP, the 43 major sources subject to the 
Printing, Coating and Dyeing of Fabrics and Other Textiles NESHAP, and 
the 16 major sources subject to the Surface Coating of Metal Furniture 
NESHAP are operating in the United States and will be affected by these 
final rules.

B. What are the air quality impacts?

    We are not establishing new emission limits and are not requiring 
additional controls; therefore, no air quality impacts are expected as 
a result of the final amendments to the rule. Requiring periodic 
performance testing has the potential to reduce excess emissions from 
sources using poorly performing add-on controls, even though facilities 
are required to be in compliance at all times.
    The final amendments will have no effect on the energy needs of the 
affected facilities in any of the three source categories, and would, 
therefore, have no indirect or secondary air emissions impacts.

C. What are the cost impacts?

    We estimate that each facility in the three source categories will 
experience costs as a result of these final amendments for reporting. 
Specifically, each facility will experience costs to read and 
understand the rule amendments. Costs associated with elimination of 
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 estimate that in the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category, 13 facilities using 18 control 
devices may be affected by the final rule requirements to conduct 
control device performance testing no less frequently than every 5 
years. It is also assumed that 5 percent of the tests will need to be 
repeated, so that 19 total performance tests will be required. The 
total annualized cost will be about $4,400 per control device, with 
additional tests of control devices at the same facility costing 25 
percent less due to reduced travel costs. The total annualized cost is 
approximately $77,000 per year for the source category, including 
retests, with an additional $3,300 in reporting costs per test in the 
year in which the test occurs.
    We estimate that no facilities in the Surface Coating of Large 
Appliances source category nor in the Surface

[[Page 9606]]

Coating of Metal Furniture source category will be affected by the 
final rule requirements to conduct control device performance testing 
no less frequently than every 5 years. Only one facility in those two 
categories is currently using add-on controls to comply, and it is 
already required to conduct performance tests as a condition of their 
operating permit.
    For further information on the potential costs, see the memoranda 
titled Estimated Costs/Impacts of the 40 CFR Part 63 Subparts NNNN, 
OOOO and RRRR Monitoring Reviews, February 2018, in the Surface Coating 
of Large Appliances Docket, Printing, Coating, and Dyeing of Fabrics 
and Other Textiles Docket, and Surface Coating of Metal Furniture 
Docket.

D. What are the economic impacts?

    For the final revisions to the NESHAP for the Surface Coating of 
Large Appliances, the total cost in 2019 is estimated to be $23,000 (in 
2016 dollars) for the 10 affected entities and is expected to range 
from 0.000002 to 0.02 percent of annual sales revenue per affected 
entity. 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 NESHAP for the Printing, Coating, 
and Dyeing of Fabrics and Other Textiles, the total cost in 2019 is 
estimated to be $90,000 (in 2016 dollars) for the 43 affected entities. 
Thirteen facilities will also incur performance testing and additional 
reporting costs, which we assume will occur in 2021. The annualized 
cost of each performance test is approximately $4,400, with additional 
tests of control devices at the same facility costing 25 percent less 
due to reduced travel costs. The reporting cost for each test is 
approximately $3,100. The 2018 equivalent annualized value of the 
present value of the costs (in 2016 dollars) for the analysis period 
(2019-2025) is estimated to be approximately $72,000 annually when 
assuming a 3-percent discount rate and $75,000 annually when assuming a 
7-percent discount rate. The estimated maximum cost faced by affected 
entities is expected to range from 0.00002 to 0.42 percent of annual 
sales revenue per ultimate owner of affected entities. 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 NESHAP for the Surface Coating of 
Metal Furniture, the total cost in 2019 is estimated to be $32,000 (in 
2016 dollars) for the 16 affected entities and is expected to range 
from 0.00007 to 0.02 percent of annual sales revenue per ultimate owner 
of affected entities. 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.

E. What are the benefits?

    As stated in section V.B. of the September 12, 2018, RTR proposal 
(83 FR 46311), we were unable to quantify the specific emissions 
reductions associated with eliminating the SSM exemption. We also are 
unable to quantify potential environmental benefits as a result of 
adding the requirement to conduct periodic add-on control device 
performance tests (e.g., reduced emissions of organic HAP during 
periods of non-compliance). However, any reduction in HAP emissions 
would be expected to provide health benefits in the form of improved 
air quality and less exposure to potentially harmful chemicals.

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. Its main provision 
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 the source category, we performed a 
demographic analysis, 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 Large Appliances
    The results of the demographic analysis for the Surface Coating of 
Large Appliances source category indicate that, for two of the 11 
demographic groups, ``African American'' and ``Below the Poverty 
Level,'' the percentage of the population living within 5 kilometers 
(km) of facilities in the source category is greater than the 
corresponding national percentage for the same demographic groups. When 
examining the risk levels of those exposed to emissions from large 
appliance coating facilities, we find that no one is exposed to a 
cancer risk at or above 1-in-1 million or to a chronic noncancer hazard 
index (HI) greater than 1 based on actual emissions from the source 
category.
    The methodology and the results of the demographic analysis are 
presented in a technical report titled Risk and Technology Review--
Analysis of Demographic Factors for Populations Living Near Surface 
Coating of Large Appliances Source Category Operations in the Surface 
Coating of Large Appliances Docket.
2. Printing, Coating, and Dyeing of Fabrics and Other Textiles
    The results of the demographic analysis for the Printing, Coating, 
and Dyeing of Fabrics and Other Textiles source category are summarized 
in Table 5 of this preamble. These results, for various demographic 
groups, are based on the estimated risks from actual emissions levels 
for the population living within 50 km of the facilities.

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

Textiles Docket.
3. Surface Coating of Metal Furniture
    The results of the demographic analysis for the Surface Coating of 
Metal Furniture source category are summarized in Table 6 below. These 
results, for various demographic groups, are based on the estimated 
risks from actual emissions levels for the population living within 50 
km of the facilities.

    The results of the Surface Coating of Metal Furniture source 
category demographic analysis indicate that emissions from the source 
category expose approximately 2,100 people to a cancer risk at or above 
1-in-1 million and no one to a chronic noncancer HI greater than 1. The 
percentages of the at-risk population in the following specific 
demographic groups are higher than their respective nationwide 
percentages: ``Hispanic or Latino,'' ``Over 25 Without a High School 
Diploma,'' and ``Below the Poverty Level.''
    The methodology and the results of the demographic analysis are 
presented in the technical report, Risk and Technology Review--Analysis 
of Demographic Factors for Populations Living Near Surface Coating of 
Metal Furniture Source Category Operations, available in the Surface 
Coating of Metal Furniture Docket.

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

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe the environmental health or safety 
risks addressed by this action present a disproportionate risk to 
children. This action's health and risk assessments are summarized in 
section IV.A of this preamble and are further documented in the Large 
Appliances Risk Assessment Report, Fabrics and Other Textiles Risk 
Assessment Report, and Metal Furniture Risk Assessment Report in the 
Surface Coating of Large Appliances Docket, Printing, Coating, and 
Dyeing of Fabrics and Other Textiles Docket, and Surface Coating of 
Metal Furniture Docket, respectively.

can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

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

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

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

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

C. Paperwork Reduction Act (PRA)

    The information collection activities in each of these three 
subparts have been submitted for approval to OMB under the PRA.
1. Surface Coating of Large Appliances
    The Information Collection Request (ICR) document that the EPA 
prepared has been assigned EPA ICR number 1954.08. You can find a copy

    As part of the RTR for the Surface Coating of Large Appliances 
NESHAP, the EPA is not revising the emission limitation requirements 
for this subpart. The EPA has revised the SSM provisions of the rule 
and is requiring the use of electronic data reporting for future 
performance test data submittals and semi-annual reporting. This 
information would be collected to assure compliance with 40 CFR part 
63, subpart NNNN. The EPA is finalizing a requirement to conduct 
control device performance testing no less frequently than once every 5 
years for facilities using the emission rate with add-on controls 
compliance option, but this is not estimated to affect any facilities 
in this source category.
    Respondents/affected entities: Facilities performing surface 
coating of large appliances.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart NNNN).
    Estimated number of respondents: In the 3 years after the 
amendments are final, approximately 10 respondents per year would be 
subject to the NESHAP and no additional respondents are expected to 
become subject to the NESHAP during that period.

[[Page 9609]]

    Frequency of response: The total number of responses in year 1 is 
30. Years 2 and 3 would have no responses.
    Total estimated burden: The average annual burden to the large 
appliance facilities over the 3 years after the amendments are final is 
estimated to be 77 hours (per year). The average annual burden to the 
Agency over the 3 years after the amendments are final is estimated to 
be 15 hours (per year) for the Agency. Burden is defined at 5 CFR 
1320.3(b).
    Total estimated cost: The average annual cost to the large 
appliance facilities is $7,700 in labor costs, in the first 3 years 
after the amendments are final. The total average annual Agency cost 
over the first 3 years after the amendments are final is estimated to 
be $700.
2. Printing, Coating, and Dyeing of Fabrics and Other Textiles
    The ICR document that the EPA prepared has been assigned EPA ICR 
number 2071.08. You can find a copy of the ICR in the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles Docket (Docket ID No. 
EPA-HQ-OAR-2017-0668), and it is briefly summarized here.
    As part of the RTR for the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles NESHAP, the EPA is not revising the emission 
limitation requirements for this subpart. The EPA has revised the SSM 
provisions of the rule and is requiring the use of electronic data 
reporting for future performance test data submittals and semiannual 
reports. This information is being collected to assure compliance with 
40 CFR part 63, subpart OOOO. The EPA is finalizing a requirement to

at 5 CFR 1320.3(b).
    Total estimated cost: The average annual cost to the metal 
furniture facilities is $11,000 in labor costs in the first 3 years 
after the amendments are final. The total average annual Agency cost 
over the first 3 years after the amendments are final is estimated to 
be $1,200.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9.

D. Regulatory Flexibility Act (RFA)

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

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. The

[[Page 9610]]

action imposes no enforceable duty on any state, local, or tribal 
governments or the private sector.

F. Executive Order 13132: Federalism

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

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

    This action does not have tribal implications as specified in 
Executive Order 13175. No tribal facilities are known to be engaged in 
any of the industries that would be affected by this action (large 
appliances surface coating; printing, coating, and dyeing of fabrics 
and other textiles; surface coating of metal furniture). Thus, 
Executive Order 13175 does not apply to this action.

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

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe the environmental health or safety 
risks addressed by this action present a disproportionate risk to 
children. This action's health and risk assessments are contained in 
sections IV.A of this preamble.

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

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

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

    This action involves technical standards. The EPA amended the three 
NESHAP in this action to provide owners and operators with the option 
of conducting EPA Method 18 of appendix A to 40 CFR part 60, 
``Measurement of Gaseous Organic Compound Emissions by Gas 
Chromatography,'' to measure and subtract methane emissions from 
measured total gaseous organic mass emissions as carbon.
    For the Surface Coating of Metal Furniture NESHAP, the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles NESHAP, and the 
Surface Coating of Large Appliances NESHAP, the EPA incorporates by 
reference ASTM D2369-10 (2015)\e\, ``Test Method for Volatile Content 
of Coatings,'' which describes a procedure for the determination of the 
weight percent volatile content of solvent-borne and water-borne 
coatings, as an acceptable alternative to EPA Method 24, 
``Determination of Volatile Matter Content, Water Content, Density, 
Volume Solids, and Weight Solids of Surface Coatings.''
    For the Surface Coating of Large Appliances NESHAP, the EPA 
incorporates by reference ASTM D2111-10 (2015), ``Standard Test Methods 
for Specific Gravity of Halogenated Organic Solvents and Their 
Admixtures,'' These test methods cover the determination of the 
specific gravity of halogenated organic solvents and solvent 
admixtures. In addition. the EPA incorporates by reference ASTM D1475-
13, ``Standard Test Method for Density of Liquid Coatings, Inks, and 
Related Products,'' which is already specified in 40 CFR part 63, 
subpart NNNN, and covers the measurement of density of paints, inks, 
varnishes, lacquers, and components thereof, other than pigments, when 
in fluid form.
    We found three voluntary consensus standards already allowed in the 
Surface Coating of Large Appliances NESHAP and the Surface Coating of 
Metal Furniture NESHAP that have been replaced with newer versions of 
the methods. ASTM Dl475-13, ``Standard Test Method for Density of 
Liquid Coatings, Inks, and Related Products,'' has replaced ASTM D1475-
90; ASTM D2697-03 (2014),''Standard Test Method for Volume Nonvolatile 
Matter in Clear or Pigmented Coatings,'' believed to be applicable to 
the determination of the volume of nonvolatile matter of a variety of 
coatings, has replaced ASTM D2697-86 (1998); and ASTM D6093-97 (2016), 
``Standard Test Method for Percent Volume Nonvolatile Matter in Clear 
or Pigmented Coatings Using Helium Gas Pycnometer,'' which covers the 
determination of the percent volume nonvolatile matter of a variety of 
clear and pigmented coatings, has replaced ASTM D6093-97 (2003).
    The ASTM standards are available from the American Society for 
Testing and Materials (ASTM), 100 Barr Harbor Drive, Post Office Box 
C700, West Conshohocken, PA 19428-2959. See https://www.astm.org/.
    The EPA decided not to include certain other voluntary consensus 
standards; these methods are impractical as alternatives because of the 
lack of equivalency, documentation, validation date, and other 
important technical and policy considerations. The search and review 
results have been documented and are in the memoranda titled Voluntary 
Consensus Standard Results for Surface Coating of Large Appliances, 
March 2018, Voluntary Consensus Standard Results for Printing, Coating, 
and Dyeing of Fabrics and Other Textiles, March 2018, and Voluntary 
Consensus Standard Results for Surface Coating of Metal Furniture, 
March 2018, in the Surface Coating of Large Appliances Docket (Docket 
ID No. EPA-HQ-OAR-2017-0670), Printing, Coating, and Dyeing of Fabrics 
and Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668), and 
Surface Coating of Metal Furniture Docket (Docket ID No. EPA-HQ-OAR-
2017-0669), respectively, for the reasons for these determinations.
    Under 40 CFR 63.7(f) and 40 CFR 63.8(f) of subpart A of the General 
Provisions, a source may apply to the EPA for permission to use 
alternative test methods or alternative monitoring requirements in 
place of any required testing methods, performance specifications, or 
procedures in the final rule or any amendments.

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

    The EPA believes that these final actions do not have 
disproportionately high and adverse human health or environmental 
effects on minority populations, low-income populations, and/or 
indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, 
February 16, 1994). This action increases the level of environmental 
protection for all affected populations. The results of this evaluation 
are contained in section IV.A of this preamble and the technical 
reports, Risk and Technology Review--Analysis of Demographic Factors 
for Populations Living Near Printing, Coating, and Dyeing of Fabrics 
and Other Textiles Source Category Operations, September 2017; Risk and 
Technology Review--Analysis of Demographic Factors for Populations 
Living Near Surface Coating of Metal Furniture Source Category 
Operations, October 2017; and Risk and Technology Review--Analysis of 
Demographic Factors for Populations Living Near Surface Coating of 
Large Appliances Source Category Operations Demographic Analysis, 
September 2017, which are available in the dockets for this action.

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


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

* * * * *
    (b) Before September 12, 2019, you must always operate and maintain 
your affected source, including all air pollution control and 
monitoring equipment you use for purposes of complying with this 
subpart, according to the provisions in Sec.  63.6(e)(1)(i). On and 
after September 12, 2019, at all times, the owner or operator must 
operate and maintain any affected source, including associated air 
pollution control equipment and monitoring equipment, in a manner 
consistent with safety and good air pollution control practices for 
minimizing emissions. The general duty to minimize emissions does not 
require the owner or operator to make any further efforts to reduce 
emissions if levels required by the applicable standard have been 
achieved. Determination of whether a source is operating in compliance 
with operation and maintenance requirements will be based on 
information available to the Administrator that may include, but is not 
limited to, monitoring results, review of operation and maintenance 
procedures, review of operation and maintenance records, and inspection 
of the affected source.
* * * * *
    (d) Before September 12, 2019, if your affected source uses an 
emission capture system and add-on control device, you must develop a 
written startup, shutdown, and malfunction plan according to the 
provisions in Sec.  63.6(e)(3). The plan must address the startup, 
shutdown, and corrective actions in the event of a malfunction of the 
emission capture system or the add-on control device. The plan must 
also address any coating operation equipment that may cause increased 
emissions or that would affect capture efficiency if the process 
equipment malfunctions, such as conveyors that move parts among 
enclosures. A startup, shutdown, and malfunction plan is not required 
on and after September 12, 2019.

6. Section 63.4121 is added to read as follows:


Sec.  63.4121  What are my electronic reporting requirements?

    (a) Beginning no later than June 13, 2019, you must submit the 
results of the performance test required in Sec.  63.4120(h) following 
the procedure specified in paragraphs (a)(1) through (3) of this 
section.
    (1) For data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test, you must submit the 
results of the performance test to the EPA via the Compliance and 
Emissions Data Reporting Interface (CEDRI). The CEDRI interface can be 
accessed through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). Performance test data must be submitted in a file format 
generated through the use of the EPA's ERT or an alternate electronic 
file format consistent with the extensible markup language (XML) schema 
listed on the EPA's ERT website.
    (2) For data collected using test methods that are not supported by 
the EPA's ERT as listed on the EPA's ERT website at the time of the 
test, you must submit the results of the performance test to the 
Administrator at the appropriate address listed in Sec.  63.13, unless 
the Administrator agrees to or specifies an alternate reporting method.
    (3) If you claim that some of the performance test information 
being submitted under paragraph (a)(1) of this section is confidential 
business information (CBI), you must submit a complete file generated 
through the use of the EPA's ERT or an alternate electronic file 
consistent with the XML schema listed on the EPA's ERT

[[Page 9614]]

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 must 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 
ERT or alternate file with the CBI omitted must be submitted to the EPA 
via the EPA's CDX as described in paragraph (a)(1) of this section.
    (b) Beginning on March 15, 2021, the owner or operator shall submit 
the initial notifications required in Sec.  63.9(b) and the 
notification of compliance status required in Sec.  63.9(h) and Sec.  
63.4110(a)(2) and (b) to the EPA via CEDRI. The CEDRI can be accessed 
through the EPA's CDX (https://cdx.epa.gov). The owner or operator must 
upload to CEDRI an electronic copy of each applicable notification in 
portable document format (PDF). The applicable notification must be 
submitted by the deadline specified in this subpart, regardless of the 
method in which the reports are submitted. Owners or operators who 
claim that some of the information required to be submitted via CEDRI 
is CBI shall submit a complete report generated using the appropriate 
form in CEDRI or an alternate electronic file consistent with the XML 
schema listed on the EPA's CEDRI website, including information claimed 
to be CBI, on a compact disc, flash drive, or other commonly used 
electronic storage medium to the EPA. The electronic medium shall be 
clearly marked as CBI and mailed to U.S. EPA/OAQPS/CORE CBI Office, 
Attention: Group Leader, Measurement Policy Group, MD C404-02, 4930 Old 
Page Rd., Durham, NC 27703. The same file with the CBI omitted shall be 
submitted to the EPA via the EPA's CDX as described earlier in this 
paragraph.
    (c) Beginning on March 15, 2021, or once the reporting template has 
been available on the CEDRI website for 1 year, whichever date is 
later, the owner or operator shall submit the semiannual compliance 
report required in Sec.  63.4120 to the EPA via CEDRI. The CEDRI 
interface can be accessed through the EPA's CDX (https://cdx.epa.gov). 
The owner or operator must use the appropriate electronic template on 
the CEDRI website for this subpart or an alternate electronic file 
format consistent with the XML schema listed on the CEDRI website 
(https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The date report templates 
become available will be listed on the CEDRI website. If the reporting 
form for the semiannual compliance report specific to this subpart is 
not available in CEDRI at the time that the report is due, you must 
submit the report to the Administrator at the appropriate addresses 
listed in Sec.  63.13. Once the form has been available in CEDRI for 1 
year, you must begin submitting all subsequent reports via CEDRI. The 
reports must be submitted by the deadlines specified in this subpart, 
regardless of the method in which the reports are submitted. Owners or 
operators who claim that some of the information required to be 
submitted via CEDRI is CBI shall submit a complete report generated 
using the appropriate form in CEDRI or an alternate electronic file 
consistent with XML schema listed on the EPA's CEDRI website, including 
information claimed to be CBI, on a compact disc, flash drive, or other 
commonly used electronic storage medium to the EPA. The electronic 
medium shall be clearly marked as CBI and mailed to U.S. EPA/OAQPS/CORE 
CBI Office, Attention: Group Leader, Measurement Policy Group, MD C404-
02, 4930 Old Page Rd., Durham, NC 27703. The same file with the CBI 
omitted shall be submitted to the EPA via the EPA's CDX as described 
earlier in this paragraph.
    (d) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, and due to a planned or actual outage of either 
the EPA's CEDRI or CDX systems within the period of time beginning 5 
business days prior to the date that the submission is due, you will be 
or are precluded from accessing CEDRI or CDX and submitting a required 
report within the time prescribed, you may assert a claim of EPA system 
outage for failure to timely comply with the reporting requirement. You 
must submit notification to the Administrator in writing as soon as 
possible following the date you first knew, or through due diligence 
should have known, that the event may cause or caused a delay in 
reporting. You must provide to the Administrator a written description 
identifying the date, time and length of the outage; a rationale for 
attributing the delay in reporting beyond the regulatory deadline to 
the EPA system outage; describe the measures taken or to be taken to 
minimize the delay in reporting; and identify a date by which you 
propose to report, or if you have already met the reporting requirement 
at the time of the notification, the date you reported. In any 
circumstance, the report must be submitted electronically as soon as 
possible after the outage is resolved. The decision to accept the claim 
of EPA system outage and allow an extension to the reporting deadline 
is solely within the discretion of the Administrator.
    (e) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX and a force majeure event is about to occur, 
occurs, or has occurred or there are lingering effects from such an 
event within the period of time beginning 5 business days prior to the 
date the submission is due, the owner or operator may assert a claim of 
force majeure for failure to timely comply with the reporting 
requirement. For the purposes of this section, a force majeure event is 
defined as an event that will be or has been caused by circumstances 
beyond the control of the affected facility, its contractors, or any 
entity controlled by the affected facility that prevents you from 
complying with the requirement to submit a report electronically within 
the time period prescribed. Examples of such events are acts of nature 
(e.g., hurricanes, earthquakes, or floods), acts of war or terrorism, 
or equipment failure or safety hazard beyond the control of the 
affected facility (e.g., large scale power outage). If you intend to 
assert a claim of force majeure, you must submit notification to the 
Administrator in writing as soon as possible following the date you 
first knew, or through due diligence should have known, that the event 
may cause or caused a delay in reporting. You must provide to the 
Administrator a written description of the force majeure event and a 
rationale for attributing the delay in reporting beyond the regulatory 
deadline to the force majeure event; describe the measures taken or to 
be taken to minimize the delay in reporting; and identify a date by 
which you propose to report, or if you have already met the reporting 
requirement at the time of the notification, the date you reported. In 
any circumstance, the reporting must occur as soon as possible after 
the force majeure event occurs. The decision to accept the claim of 
force majeure and allow an extension to the reporting deadline is 
solely within the discretion of the Administrator.

subpart that are in reports that were submitted electronically via the 
EPA's CEDRI may be maintained in electronic format. This ability to 
maintain electronic copies does not affect the requirement for 
facilities to make records, data, and reports available upon request to 
a delegated air agency or the EPA as part of an on-site compliance 
evaluation.

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


Sec.  63.4141  How do I demonstrate initial compliance with the 
emission limitations?

* * * * *
    (a) * * *
    (1) * * *
    (i) Count each organic HAP in Table 5 to this subpart that is 
measured to be present at 0.1 percent by mass or more and at 1.0 
percent by mass or more for other organic HAP compounds. For example, 
if toluene (not listed in Table 5 to this subpart) is measured to be 
0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (for example, 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24 in appendix A-7 of part 60. For coatings, you may use 
Method 24 to determine the mass fraction of nonaqueous volatile matter 
and use that value as a substitute for mass fraction of organic HAP. As 
an alternative to using Method 24, you may use ASTM D2369-10 (R2015), 
``Test Method for Volatile Content of Coatings'' (incorporated by 
reference, see Sec.  63.14).
* * * * *
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, 
such as manufacturer's formulation data if they represent each organic 
HAP in Table 5 to this subpart that is present at 0.1 percent by mass 
or more and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not listed in Table 5 to this 
subpart) is 0.5 percent of the material by mass, you do not have to 
count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence.
* * * * *
    (b) * * *
    (1) ASTM D2697-03 (R2014) or D6093-97 (R2016). You may use ASTM 
D2697-03 (R2014), ``Standard Test Method for Volume Nonvolatile Matter 
in Clear or Pigmented Coatings,'' or D6093-97 (R2016), ``Standard Test 
Method for Percent Volume Nonvolatile Matter in Clear or Pigmented 
Coatings Using a Helium Gas Pycnometer'' (incorporated by reference, 
see Sec.  63.14) to determine the volume fraction of coating solids for 
each coating. Divide the nonvolatile volume percent obtained with the 
methods by 100 to calculate volume fraction of coating solids.
* * * * *
    (3) * * *

mvolatiles = total volatile matter content of the 
coating, including HAP, volatile organic compounds (VOC), water, and 
exempt compounds, determined according to Method 24 in appendix A-7 
of part 60, or according to ASTM D2369-10 (R2015) Standard Test 
Method for Volatile Content of Coatings (incorporated by reference, 
see Sec.  63.14), grams volatile matter per liter coating.
Davg = average density of volatile matter in the coating, 
grams volatile matter per liter volatile matter, determined from 
test results using ASTM D1475-13, ``Standard Test Method for Density 
of Liquid Coatings, Inks, and Related Products,'' ASTM D2111-10 
(R2015), ``Standard Test Methods for Specific Gravity of Halogenated 
Organic Solvents and Their Admixtures'' (both incorporated by 
reference, see Sec.  63.14); if you use this method, the specific 
gravity must be corrected to a standard temperature, information 
from the supplier or manufacturer of the material, or reference 
sources providing density or specific gravity data for pure 
materials. If there is disagreement between ASTM D1475-13 or ASTM 
D2111-10 (R2015) test results and other information sources, the 
test results will take precedence.

    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM D1475-13, ``Standard Test Method for Density of Liquid Coatings, 
Inks, and Related Products, ASTM D2111-10

[[Page 9616]]

(R2015), ``Standard Test Methods for Specific Gravity of Halogenated 
Organic Solvents and Their Admixtures''(both incorporated by reference, 
see Sec.  63.14); if you use this method, the specific gravity must be 
corrected to a standard temperature, information from the supplier or

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


Sec.  63.4161  How do I demonstrate initial compliance?

* * * * *
    (g) Calculate the organic HAP emissions reduction for controlled 
coating operations not using liquid-liquid material balance. For each 
controlled coating operation using an emission capture system and add-
on control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate organic HAP 
emissions reduction, using Equation 1 of this section, by applying the 
emission capture system efficiency and add-on control device efficiency 
to the mass of organic HAP contained in the coatings, thinners, and 
cleaning materials that are used in the coating operation served by the 
emission capture system and add-on control device during the compliance 
period. For any period of time a deviation specified in Sec.  
63.4163(c) or (d) occurs in the controlled coating operation, you must 
assume zero efficiency for the emission capture system and add-on 
control device. For the purposes of completing the compliance 
calculations, you must treat the materials used during a deviation on a 
controlled coating operation as if they were used on an uncontrolled 
coating operation for the time period of the deviation. You must not 
include those materials in the calculations of organic HAP emissions 
reduction in Equation 1 of this section.

Where:
HC = mass of organic HAP emissions reduction for the 
controlled coating operation during the compliance period, kg.
AI = total mass of organic HAP in the coatings used in 
the controlled coating operation, kg, as calculated in Equation 1A 
of this section.
BI = total mass of organic HAP in the thinners used in 
the controlled coating operation, kg, as calculated in Equation 1B 
of this section.
CI = total mass of organic HAP in the cleaning materials 
used in the controlled coating operation during the compliance 
period, kg, as calculated in Equation 1C of this section.
CE = capture efficiency of the emission capture system vented to the 
add-on control device, percent. Use the test methods and procedures 
specified in Sec. Sec.  63.4164 and 63.4165 to measure and record 
capture efficiency.
DRE = organic HAP destruction or removal efficiency of the add-on 
control device, percent. Use the test methods and procedures in 
Sec. Sec.  63.4164 and 63.4166 to measure and record the organic HAP 
destruction or removal efficiency.

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

practice standards that must be reported as specified in Sec. Sec.  
63.4110(b)(6) and 63.4120(g).
* * * * *
    (h) Before September 12, 2019, consistent with Sec. Sec.  63.6(e) 
and 63.7(e)(1), deviations that occur during a period of startup, 
shutdown, or malfunction of the emission capture system, add-on control 
device, or 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). The Administrator will determine whether deviations that 
occur during a period of startup, shutdown, or malfunction are 
violations according to the provisions in Sec.  63.6(e). On and after 
September 12, 2019, as specified in Sec.  63.4100(b), at all times, the 
owner or operator must operate and maintain any affected source, 
including associated air pollution control equipment and monitoring 
equipment, in a manner consistent with safety and good air pollution 
control practices for minimizing emissions, and determination of 
whether a source is operating in compliance with operation and 
maintenance requirements will be based on information available to the 
Administrator.

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


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

    (a) * * *
    (3) * * *
    (i) Before September 12, 2019, the web coating/printing or dyeing/
finishing operation(s) must be in compliance with the applicable 
emission limit in Table 1 to this subpart or minimize emissions at all 
times as required by Sec.  63.6(e)(1). On and after September 12, 2019, 
the web coating/printing or dyeing/finishing operation(s) must be in 
compliance with the applicable emission limit in Table 1 to this 
subpart at all times.
* * * * *
    (b) Before September 12, 2019, you must always operate and maintain 
your affected source, including air pollution control and monitoring 
equipment, according to the provisions in Sec.  63.6(e)(1)(i). On and 
after September 12, 2019, at all times, the owner or operator must 
operate and maintain any affected source, including associated air 
pollution control equipment and monitoring equipment, in a manner 
consistent with safety and good air pollution control practices for 
minimizing emissions. The general duty to minimize emissions does not 
require the owner or operator to make any further efforts to reduce 
emissions if levels required by the applicable standard have been 
achieved. Determination of whether a source is operating in compliance 
with operation and maintenance requirements will be based on 
information available to the Administrator that may include, but is not 
limited to, monitoring results, review of operation and maintenance 
procedures, review of operation and maintenance records, and inspection 
of the affected source.
    (c) Before September 12, 2019, if your affected source uses an 
emission capture system and add-on control device, you must develop a 
written startup, shutdown, and malfunction plan according to the 
provisions in Sec.  63.6(e)(3). The plan must address the startup, 
shutdown, and corrective actions in the event of a malfunction of the 
emission capture system or the add-on control device. The plan must 
also address any web coating/printing or dyeing/finishing operation 
equipment such as conveyors that move the substrate among enclosures 
that may cause increased emissions or that would affect capture 
efficiency if the process equipment malfunctions. A startup, shutdown, 
and malfunction plan is not required on and after September 12, 2019.

compliance period during which the deviation occurred, the number of 
deviations during the compliance period, and, for each deviation, the 
date, time, and duration of the deviation; a list of the affected 
sources or equipment; and a statement of the cause of the deviation 
(including an unknown cause, if applicable).
* * * * *
    (c) Before September 12, 2019, if you use one of the add-on control 
options in Sec.  63.4291(a) or (c) and you have a startup, shutdown, or 
malfunction during the semiannual reporting period, you must submit the 
reports specified in paragraphs (c)(1) and (2) of this section. The 
reports specified in paragraphs (c)(1) and (2) of this section are not 
required on and after September 12, 2019.
* * * * *
    (d) Beginning no later than June 13, 2019, you must submit the 
results of the performance test required in paragraph (b) of this 
section following the procedure specified in paragraphs (d)(1) through 
(3) of this section.
    (1) For data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test, you must submit the 
results of the performance test to the EPA via the Compliance and 
Emissions Data Reporting Interface (CEDRI). The CEDRI interface can be 
accessed through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). Performance test data must be submitted in a file format 
generated through the use of the EPA's ERT or an alternate electronic 
file format consistent with the extensible markup language (XML) schema 
listed on the EPA's ERT website.
    (2) For data collected using test methods that are not supported by 
the EPA's ERT as listed on the EPA's ERT website at the time of the 
test, you must submit the results of the performance test to the 
Administrator at the appropriate address listed in Sec.  63.13, unless 
the Administrator agrees to or specifies an alternate reporting method.
    (3) If you claim that some of the performance test information 
being submitted under paragraph (d)(1) of this section is confidential 
business information (CBI), you must submit a complete file generated 
through the use of the EPA's ERT or an alternate electronic file 
consistent with the XML schema listed on the EPA's ERT 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 must be clearly marked as CBI and mailed to U.S. EPA/
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) Beginning on March 15, 2021, the owner or operator shall submit 
the initial notifications required in Sec.  63.9(b) and the 
notification of compliance status required in Sec.  63.9(h) and Sec.  
63.4310(c) to the EPA via CEDRI. The CEDRI interface can be accessed 
through the EPA's CDX (https://cdx.epa.gov). The owner or operator must 
upload to CEDRI an electronic copy of each applicable notification in 
portable document format (PDF). The applicable notification must be 
submitted by the deadline specified in this subpart,

[[Page 9626]]

regardless of the method in which the reports are submitted. Owners or 
operators who claim that some of the information required to be 
submitted via CEDRI is CBI shall submit a complete report generated 
using the appropriate form in CEDRI or an alternate electronic file 
consistent with the extensible markup language (XML) schema listed on 
the EPA's CEDRI website, including information claimed to be CBI, on a 
compact disc, flash drive, or other commonly used electronic storage 
medium to the EPA. The electronic medium shall be clearly marked as CBI 
and mailed to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group Leader, 
Measurement Policy Group, MD C404-02, 4930 Old Page Rd., Durham, NC 
27703. The same file with the CBI omitted shall be submitted to the EPA 
via the EPA's CDX as described earlier in this paragraph.
    (f) Beginning on March 15, 2021, or once the reporting template has 
been available on the CEDRI website for 1 year, whichever date is 
later, the owner or operator shall submit the semiannual compliance 
report required in paragraph (a) of this section to the EPA via CEDRI. 
The CEDRI interface can be accessed through the EPA's CDX (https://cdx.epa.gov). The owner or operator must use the appropriate electronic 
template on the CEDRI website for this subpart or an alternate 
electronic file format consistent with the XML schema listed on the 
CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The date 
report templates become available will be listed on the CEDRI website. 
If the reporting form for the semiannual compliance report specific to 
this subpart is not available in CEDRI at the time that the report is 
due, you must submit the report to the Administrator at the appropriate 
addresses listed in Sec.  63.13. Once the form has been available in 
CEDRI for 1 year, you must begin submitting all subsequent reports via 
CEDRI. The reports must be submitted by the deadlines specified in this 
subpart, regardless of the method in which the reports are submitted. 
Owners or operators who claim that some of the information required to 
be submitted via CEDRI is CBI shall submit a complete report generated 
using the appropriate form in CEDRI or an alternate electronic file 
consistent with the XML schema listed on the EPA's CEDRI website, 
including information claimed to be CBI, on a compact disc, flash 
drive, or other commonly used electronic storage medium to the EPA. The 
electronic medium shall be clearly marked as CBI and mailed to U.S. 
EPA/OAQPS/CORE CBI Office, Attention: Group Leader, Measurement Policy 
Group, MD C404-02, 4930 Old Page Rd., Durham, NC 27703. The same file 
with the CBI omitted shall be submitted to the EPA via the EPA's CDX as 
described earlier in this paragraph.
    (g) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, and due to a planned or actual outage of either 
the EPA's CEDRI or CDX systems within the period of time beginning 5 
business days prior to the date that the submission is due, you will be 
or are precluded from accessing CEDRI or CDX and submitting a required 
report within the time prescribed, you may assert a claim of EPA system 
outage for failure to timely comply with the reporting requirement. You 
must submit notification to the Administrator in writing as soon as 
possible following the date you first knew, or through due diligence 
should have known, that the event may cause or caused a delay in 
reporting. You must provide to the Administrator a written description 
identifying the date, time and length of the outage; a rationale for 
attributing the delay in reporting beyond the regulatory deadline to 
the EPA system outage; describe the measures taken or to be taken to 
minimize the delay in reporting; and identify a date by which you 
propose to report, or if you have already met the reporting requirement 
at the time of the notification, the date you reported. In any 
circumstance, the report must be submitted electronically as soon as 
possible after the outage is resolved. The decision to accept the claim 
of EPA system outage and allow an extension to the reporting deadline 
is solely within the discretion of the Administrator.
    (h) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX and a force majeure event is about to occur, 
occurs, or has occurred or there are lingering effects from such an 
event within the period of time beginning 5 business days prior to the 
date the submission is due, the owner or operator may assert a claim of 
force majeure for failure to timely comply with the reporting 
requirement. For the purposes of this section, a force majeure event is 
defined as an event that will be or has been caused by circumstances 
beyond the control of the affected facility, its contractors, or any 
entity controlled by the affected facility that prevents you from 
complying with the requirement to submit a report electronically within 
the time period prescribed. Examples of such events are acts of nature 
(e.g., hurricanes, earthquakes, or floods), acts of war or terrorism, 
or equipment failure or safety hazard beyond the control of the 
affected facility (e.g., large scale power outage). If you intend to 
assert a claim of force majeure, you must submit notification to the 
Administrator in writing as soon as possible following the date you 
first knew, or through due diligence should have known, that the event 
may cause or caused a delay in reporting. You must provide to the 
Administrator a written description of the force majeure event and a 
rationale for attributing the delay in reporting beyond the regulatory 
deadline to the force majeure event; describe the measures taken or to 
be taken to minimize the delay in reporting; and identify a date by 
which you propose to report, or if you have already met the reporting 
requirement at the time of the notification, the date you reported. In 
any circumstance, the reporting must occur as soon as possible after 
the force majeure event occurs. The decision to accept the claim of 
force majeure and allow an extension to the reporting deadline is 
solely within the discretion of the Administrator.

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


Sec.  63.4312  What records must I keep?

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

[[Page 9627]]

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

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


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

    (a) Your records must be in a form suitable and readily available 
for expeditious review, according to Sec.  63.10(b)(1). Where 
appropriate, the records may be maintained as electronic spreadsheets 
or as a database. Any records required to be maintained by this subpart 
that are in reports that were submitted electronically via the EPA's 
CEDRI may be maintained in electronic format. This ability to maintain 
electronic copies does not affect the requirement for facilities to 
make records, data, and reports available upon request to a delegated 
air agency or the EPA as part of an on-site compliance evaluation.

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


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

* * * * *
    (e) * * *
    (1) * * *
    (i) * * *
    (A) Count each organic HAP in Table 6 to this subpart that is 
measured to be present at 0.1 percent by mass or more and at 1.0 
percent by mass or more for other compounds. For example, if toluene 
(not listed in Table 6 to this subpart) is measured to be 0.5 percent 
of the material by mass, you don't have to count it. Express the mass 
fraction of each organic HAP you count as a value truncated to no more 
than four places after the decimal point (e.g., 0.3791).
* * * * *
    (ii) Method 24 in appendix A-7 of part 60. You may use Method 24 to 
determine the mass fraction of nonaqueous volatile matter and use that 
value as a substitute for mass fraction of organic HAP. As an 
alternative to using Method 24, you may use ASTM D2369-10 (R2015), 
``Test Method for Volatile Content of Coatings'' (incorporated by 
reference, see Sec.  63.14). For a multi-component coating with 
reactive chemicals, you may use Method 24 or ASTM D2369-10 (R2015) on 
the coating as applied to determine the mass fraction of nonaqueous 
volatile matter and use that value as a substitute for the mass 
fraction of organic HAP determined from the sum of organic HAP in each 
component.
* * * * *
    (iv) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (e)(1)(i) through (iii) of this 
section, such as manufacturer's formulation data, if it represents each 
organic HAP in Table 6 to this subpart that is present at 0.1 percent 
by mass or more and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not listed in Table 6 to this subpart) is 0.5 
percent of the material by mass, you do not have to count it. If there 
is a disagreement between such information and results of a test 
conducted according to paragraphs (e)(1)(i) through (iii) of this 
section on coating, thinning, or cleaning material, then the test 
method results will take precedence. Information from the supplier or 
manufacturer of the printing, slashing, dyeing, or finishing material 
is sufficient for determining the mass fraction of organic HAP.
* * * * *
    (2) * * *
    (i) Method 24 in appendix A-7 of part 60. You may use Method 24 for 
determining the mass fraction of solids of coating materials. As an 
alternative to using Method 24, you may use ASTM D2369-10 (R2015), 
``Test Method for Volatile Content of Coatings'' (incorporated by 
reference, see Sec.  63.14).

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


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

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

    The additions and revision read as follows:


Sec.  63.4341  How do I demonstrate initial compliance?

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

[[Page 9628]]

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

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


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

* * * * *
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec.  63.4292 that applies to you, as specified in 
Table 2 to this subpart, and you must conduct periodic performance 
tests as specified in paragraph (c)(3) of this section.
* * * * *
    (3) Except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to Sec.  63.4351(d)(5), 
within 5 years following the previous performance test, you must 
conduct according to the procedures in Sec. Sec.  63.4360, 63.4361, and 
63.4362 a periodic performance test of each capture system and add-on 
control device used, and you must establish the operating limits 
required by Sec.  63.4292. You must conduct the first periodic 
performance test and establish the operating limits required by Sec.  
63.4292 before March 15, 2022, unless you are already required to 
complete periodic performance tests as a requirement of renewing your 
facility's operating permit under 40 CFR part 70 or 40 CFR part 71 and 
have conducted a performance test on or after March 15, 2017. 
Thereafter you must conduct a performance test no later than 5 years 
following the previous performance test. Operating limits must be 
confirmed or reestablished during each performance test.
* * * * *
    (f) As part of each semiannual compliance report required in Sec.  
63.4311, you must identify the coating/printing and dyeing/finishing 
operation(s) for which you use the emission rate with add-on controls 
option. If there were no deviations from the applicable emission 
limitations in Sec. Sec.  63.4290, 63.4292, and 63.4293, you must 
submit a statement that, as appropriate, the web coating/printing 
operations or the dyeing/finishing operations were in compliance with 
the emission limitations during the reporting period because the 
organic HAP emission rate for each compliance period was less than or 
equal to the applicable emission limit in Table 1 to this subpart, and 
you achieved the operating limits required by Sec.  63.4292 and the 
work practice standards required by Sec.  63.4293 during each 
compliance period.
* * * * *
    (h) Before September 12, 2019, consistent with Sec. Sec.  63.6(e) 
and 63.7(e)(1), deviations that occur during a period of startup, 
shutdown, or malfunction of the emission capture system, add-on control 
device, or web coating/printing or dyeing/finishing operation that may 
affect emission capture or control device efficiency are not violations 
if you demonstrate to the Administrator's satisfaction that you were 
operating in accordance with Sec.  63.6(e)(1). The Administrator will 
determine whether deviations that occur during a period of startup, 
shutdown, or malfunction are violations according to the provisions in 
Sec.  63.6(e). On and after September 12, 2019, as specified in Sec.  
63.4300(b), at all times, the owner or operator must operate and 
maintain any affected source, including associated air pollution 
control equipment and monitoring equipment, in a manner consistent with 
safety and good air pollution control practices for minimizing 
emissions, and determination of whether a source is operating in 
compliance with operation and maintenance requirements will be based on 
information available to the Administrator.

Sec.  63.4350  By what date must I conduct performance tests and other 
initial compliance demonstrations?

    (a) * * *
    (3) You must complete the compliance demonstration for the initial 
compliance period according to the requirements of Sec.  63.4351. The 
initial compliance period begins on the applicable compliance date 
specified in Sec.  63.4283 and ends on the last day of the first full 
month after the compliance date, or the date you conduct the 
performance tests of the emission capture systems and add-on control 
devices, or initiate the first liquid-liquid material balance for a 
solvent recovery system, whichever is later. The initial compliance 
demonstration includes the results of emission capture system and add-
on control device performance tests conducted according to Sec. Sec.  
63.4360, 63.4361, and 63.4362; results of liquid-liquid material 
balances conducted according to Sec.  63.4351(d)(5); calculations 
according to Sec.  63.4351 and supporting documentation showing that 
during the initial compliance period either the organic HAP overall 
control efficiency was equal to or greater than the applicable overall

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


Sec.  63.4351  How do I demonstrate initial compliance?

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

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


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

* * * * *
    (h) Before September 12, 2019, consistent with Sec. Sec.  63.6(e) 
and 63.7(e)(1), deviations that occur during a period of startup, 
shutdown, or malfunction of the emission capture system, add-on control 
device, or web coating/printing operation that may affect emission 
capture or control device efficiency are not violations if you 
demonstrate to the Administrator's satisfaction that you

[[Page 9630]]

were operating in accordance with Sec.  63.6(e)(1). The Administrator 
will determine whether deviations that occur during a period of 
startup, shutdown, or malfunction are violations according to the 
provisions in Sec.  63.6(e). On and after September 12, 2019, as 
specified in Sec.  63.4300(b), at all times, the owner or operator must 
operate and maintain any affected source, including associated air 
pollution control equipment and monitoring equipment, in a manner 
consistent with safety and good air pollution control practices for 
minimizing emissions, and determination of whether a source is 
operating in compliance with operation and maintenance requirements 
will be based on information available to the Administrator.

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


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

    (a) You must conduct each performance test required by Sec.  
63.4340 or Sec.  63.4350 according to the requirements in this section, 
unless you obtain a waiver of the performance test according to the 
provisions in Sec.  63.7(h).
    (1) Representative web coating/printing or dyeing/finishing 
operation operating conditions. You must conduct the performance test 
under representative operating conditions for the web coating/printing 
or dyeing/finishing operation. Operations during periods of startup, 
shutdown, or nonoperation do not constitute representative conditions 
for purposes of conducting a performance test. The owner or operator 
may not conduct performance tests during periods of malfunction. You 
must record the process information that is necessary to document 
operating conditions during the test and explain why the conditions 
represent normal operation. Upon request, you must make available to 
the Administrator such records as may be necessary to determine the 
conditions of performance tests.

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


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

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

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


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

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

38. Section 63.4371 is amended by revising the definition of 
``Deviation'' to read as follows:


Sec.  63.4371  What definitions apply to this subpart?

* * * * *
    Deviation means:
    (1) Before September 12, 2019, any instance in which an affected 
source subject to this subpart or an owner or operator of such a 
source:
    (i) Fails to meet any requirement or obligation established by this 
subpart

[[Page 9631]]

including but not limited to any emission limit, or operating limit, or 
work practice standard;
    (ii) Fails to meet any term or condition that is adopted to 
implement an applicable requirement in this subpart and that is 
included in the operating permit for any affected source required to 
obtain such a permit; or
    (iii) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction regardless of whether or not such failure is permitted by 
this subpart; and
    (2) On and after September 12, 2019, any instance in which an 
affected source subject to this subpart or an owner or operator of such 
a source:
    (i) Fails to meet any requirement or obligation established by this 
subpart including but not limited to any emission limit, or operating 
limit, or work practice standard; or
    (ii) Fails to meet any term or condition that is adopted to 
implement an applicable requirement in this subpart and that is 
included in the operating permit for any affected source required to 
obtain such a permit.

41. Section 63.4900 is revised to read as follows:


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

    (a) The affected source must be in compliance at all times with the 
applicable emission limitations specified in Sec. Sec.  63.4890, 
63.4892, and 63.4893.
    (b) Before September 12, 2019, you must always operate and maintain 
your affected source, including all air pollution control and 
monitoring equipment you use for purposes of complying with this 
subpart, according to the provisions in Sec.  63.6(e)(1)(i). On and 
after September 12, 2019, at all times, the owner or operator must 
operate and maintain any affected source, including associated air 
pollution control equipment and monitoring equipment, in a manner 
consistent with safety and good air pollution control practices for 
minimizing emissions. The general duty to minimize emissions does not 
require the owner or operator to make any further efforts to reduce 
emissions if levels required by the applicable standard have been 
achieved. Determination of whether a source is operating in compliance 
with operation and maintenance requirements will be based on 
information available to the Administrator that may include, but is not 
limited to, monitoring results, review of operation and maintenance 
procedures, review of operation and maintenance records, and inspection 
of the affected source.
    (c) Before September 12, 2019, if your affected source uses an 
emission capture system and add-on control device to comply with the 
emission limitations in Sec.  63.4890, you must develop a written 
startup, shutdown, and malfunction plan (SSMP) according to the 
provisions in Sec.  63.6(e)(3). The SSMP must address the startup, 
shutdown, and corrective actions in the event of a malfunction of the 
emission capture system or the add-on control device. The SSMP must 
also address any coating operation equipment that may cause increased 
emissions or that would affect capture efficiency if the process 
equipment malfunctions, such as conveyors that move parts among 
enclosures. A startup, shutdown, and malfunction plan is not required 
on and after September 12, 2019.

    (c) Beginning on March 15, 2021, or once the reporting template has 
been available on the CEDRI website for 1 year, whichever date is 
later, the owner or operator shall submit the semiannual compliance 
report required in Sec.  63.4920 to the EPA via CEDRI. The CEDRI 
interface can be accessed through the EPA's CDX (https://cdx.epa.gov).). The owner or operator must use the appropriate 
electronic template on the CEDRI website for this subpart or an 
alternate electronic file format consistent with the XML schema listed 
on the CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The 
date report templates become available will be listed on the CEDRI 
website. If the reporting form for the semiannual compliance report 
specific to this subpart is not available in CEDRI at the time that the 
report is due, you must submit the report to the Administrator at the 
appropriate addresses listed in Sec.  63.13. Once the form has been 
available in CEDRI for 1 year, you must begin submitting all subsequent 
reports via CEDRI. The reports must be submitted by the deadlines 
specified in this subpart, regardless of the method in which the 
reports are submitted. Owners or operators who claim that some of the 
information required to be submitted via CEDRI is CBI shall submit a 
complete report generated using the appropriate form in CEDRI or an 
alternate electronic file consistent with the XML schema listed on the 
EPA's CEDRI website, including information claimed to be CBI, on a 
compact disc, flash drive, or other commonly used electronic storage 
medium to the EPA. The electronic medium shall be clearly marked as CBI 
and mailed to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group Leader, 
Measurement Policy Group, MD C404-02, 4930 Old Page Rd., Durham, NC 
27703. The same file with the CBI omitted shall be submitted to the EPA 
via the EPA's CDX as described earlier in this paragraph.
    (d) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, and due to a planned or actual outage of either 
the EPA's CEDRI or CDX systems within the period of time beginning 5 
business days prior to the date that the submission is due, you will be 
or are precluded from accessing CEDRI or CDX and submitting a required 
report within

[[Page 9639]]

the time prescribed, you may assert a claim of EPA system outage for 
failure to timely comply with the reporting requirement. You must 
submit notification to the Administrator in writing as soon as possible 
following the date you first knew, or through due diligence should have 
known, that the event may cause or caused a delay in reporting. You 
must provide to the Administrator a written description identifying the 
date, time and length of the outage; a rationale for attributing the 
delay in reporting beyond the regulatory deadline to the EPA system 
outage; describe the measures taken or to be taken to minimize the 
delay in reporting; and identify a date by which you propose to report, 
or if you have already met the reporting requirement at the time of the 
notification, the date you reported. In any circumstance, the report 
must be submitted electronically as soon as possible after the outage 
is resolved. The decision to accept the claim of EPA system outage and 
allow an extension to the reporting deadline is solely within the 
discretion of the Administrator.
    (e) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX and a force majeure event is about to occur, 
occurs, or has occurred or there are lingering effects from such an 
event within the period of time beginning 5 business days prior to the 
date the submission is due, the owner or operator may assert a claim of 
force majeure for failure to timely comply with the reporting 
requirement. For the purposes of this section, a force majeure event is 
defined as an event that will be or has been caused by circumstances 
beyond the control of the affected facility, its contractors, or any 
entity controlled by the affected facility that prevents you from 
complying with the requirement to submit a report electronically within 
the time period prescribed. Examples of such events are acts of nature 
(e.g., hurricanes, earthquakes, or floods), acts of war or terrorism, 
or equipment failure or safety hazard beyond the control of the 
affected facility (e.g., large scale power outage). If you intend to 
assert a claim of force majeure, you must submit notification to the 
Administrator in writing as soon as possible following the date you 
first knew, or through due diligence should have known, that the event 
may cause or caused a delay in reporting. You must provide to the 
Administrator a written description of the force majeure event and a 
rationale for attributing the delay in reporting beyond the regulatory 
deadline to the force majeure event; describe the measures taken or to 
be taken to minimize the delay in reporting; and identify a date by 
which you propose to report, or if you have already met the reporting 
requirement at the time of the notification, the date you reported. In 
any circumstance, the reporting must occur as soon as possible after 
the force majeure event occurs. The decision to accept the claim of 
force majeure and allow an extension to the reporting deadline is 
solely within the discretion of the Administrator.

introductory text, and (k)(1) and (2) to read as follows:


Sec.  63.4930  What records must I keep?

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

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


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

    (a) Your records must be in a form suitable and readily available 
for expeditious review, according to Sec.  63.10(b)(1). Where 
appropriate, the records may be maintained as electronic spreadsheets 
or as a database. Any records required to be maintained by this subpart 
that are in reports that were submitted electronically via the EPA's 
CEDRI may be maintained in electronic format. This ability to maintain 
electronic copies does not affect the requirement for facilities to 
make records, data, and reports available upon request to a delegated 
air agency or the EPA as part of an on-site compliance evaluation.

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


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

* * * * *
    (a) * * *
    (1) * * *
    (i) Count each organic HAP in Table 5 to this subpart that is 
measured to be present at 0.1 percent by mass or more and at 1.0 
percent by mass or more for other organic HAP compounds. For example, 
if toluene (not listed in Table 5 to this subpart) is measured to be 
0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (for example, 0.3791).
* * * * *
    (2) Method 24 in appendix A-7 of part 60. For coatings, you may use 
Method 24 to determine the mass fraction of nonaqueous volatile matter 
and use that value as a substitute for mass fraction of organic HAP. As 
an alternative to using Method 24, you may use ASTM D2369-10 (R2015), 
``Test Method for Volatile Content of Coatings'' (incorporated by 
reference, see Sec.  63.14).
* * * * *
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, 
such as manufacturer's formulation data, if it represents each organic 
HAP in Table 5 to this subpart that is present at 0.1 percent by mass 
or

[[Page 9640]]

more and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not listed in Table 5 to this 
subpart) is 0.5 percent of the material by mass, you do not have to 
count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence.
* * * * *
    (b) * * *
    (1) Test results. You may use ASTM D2697-03 (R2014), ``Standard 
Test Method for Volume Nonvolatile Matter in Clear or Pigmented 
Coatings'', or D6093-97 (R2016), ``Standard Test Method for Percent 
Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium 
Gas Pycnometer'' (both incorporated by reference, see Sec.  63.14), to 
determine the volume fraction of coating solids for each coating. 
Divide the nonvolatile volume percent obtained with the methods by 100 
to calculate volume fraction of coating solids. Alternatively, you may 
use another test method once you obtain approval from the Administrator 
according to the requirements of Sec.  63.7(f).
* * * * *
    (3) * * *

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

    (c) Determine the density of each coating. You must determine the 
density of each coating used during the compliance period from test 
results using ASTM D1475-13, ``Standard Test Method for Density of 
Liquid Coatings, Inks, and Related Products'' (incorporated by 
reference, see Sec.  63.14), or information from the supplier or 
manufacturer of the material. If there is disagreement between ASTM 
D1475-13 test results and the supplier's or manufacturer's information, 
the test results will take precedence.
* * * * *
    (e) Compliance demonstration. The calculated organic HAP content 
for each coating used during the initial compliance period must be less 
than or equal to the applicable emission limit in Sec.  63.4890 and 
each thinner and cleaning material used during the initial compliance 
period must contain no organic HAP, determined according to paragraph 
(a) of this section. You must keep all records required by Sec. Sec.  
63.4930 and 63.4931. As part of the Notification of Compliance Status 
required in Sec.  63.4910(c) and the semiannual compliance reports 
required in Sec.  63.4920, you must identify each coating operation and 
group of coating operations for which you used the compliant material 
option. If there were no deviations from the emission limit, include a 
statement that each coating operation was in compliance with the 
emission limitations during the initial compliance period because it 
used no coatings for which the organic HAP content exceeded the 
applicable emission limit in Sec.  63.4890, and it used no thinners or 
cleaning materials that contained organic HAP.

text and (j)(3) to read as follows:


Sec.  63.4961  How do I demonstrate initial compliance?

* * * * *
    (h) Calculate the organic HAP emission reduction for controlled 
coating operations not using liquid-liquid material balance. For each 
controlled coating operation using an emission capture system and add-
on control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate the organic HAP 
emission reduction, using Equation 1 of this section. The calculation 
applies the emission capture system efficiency and add-on control 
device efficiency to the mass of organic HAP contained in the coatings, 
thinners, and cleaning materials that are used in the coating operation 
served by the emission capture system and add-on control device during 
the compliance period. For any period of time a deviation specified in 
Sec.  63.4962(c) or (d) occurs in the controlled coating operation, you 
must assume zero efficiency for the emission capture system and add-on 
control device. Equation 1 of this section treats the materials used 
during such a deviation as if they were used on an uncontrolled coating 
operation for the time period of the deviation:
[GRAPHIC] [TIFF OMITTED] TR15MR19.001

Where:

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

[[Page 9641]]

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

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

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

* * * * *
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec.  63.4892 that applies to you, as specified in 
Table 1 to this subpart, and you must conduct periodic performance 
tests as specified in paragraph (c)(3) of this section.
* * * * *
    (3) Except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to Sec.  63.4961(j), within 5 
years following the previous performance test, you must conduct 
according to the procedures in Sec. Sec.  63.4963, 63.4964, and 63.4965 
a periodic performance test of each capture system and add-on control 
device used, and you must establish the operating limits required by 
Sec.  63.4892. You must conduct the first periodic performance test and 
establish the operating limits required by Sec.  63.4892 before March 
15, 2022, unless you are already required to complete periodic 
performance tests as a requirement of renewing your facility's 
operating permit under 40 CFR part 70 or 40 CFR part 71 and have 
conducted a performance test on or after March 15, 2017. Thereafter you 
must conduct a performance test no later than 5 years following the 
previous performance test. Operating limits must be confirmed or 
reestablished during each performance test.

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


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

    (a) You must conduct each performance test required by Sec. Sec.  
63.4960 and 63.4962 according to the requirements in this section 
unless you obtain a waiver of the performance test according to the 
provisions in Sec.  63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or nonoperation do not constitute representative conditions 
for purposes of conducting a performance test. The owner or operator 
may not conduct performance tests during periods of malfunction. You 
must record the process information that is necessary to document 
operating conditions during the test and explain why the conditions 
represent normal operation. Upon request, you must make available to 
the Administrator such records as may be necessary to determine the 
conditions of performance tests.

flow rate.
    (3) Use Method 3, 3A, or 3B in appendix A-2 of part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You 
may also use as an alternative to Method 3B, the manual method for 
measuring the oxygen, carbon dioxide, and carbon monoxide content of 
exhaust gas in ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas 
Analyses [Part 10, Instruments and Apparatus]'' (incorporated by 
reference, see Sec.  63.14).
