40 CFR Part 63

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: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing the 
results of the residual risk and technology reviews (RTR) for three 
rules--the National Emission Standards for Hazardous Air Pollutants 
(NESHAP) for the Surface Coating of Large Appliances; the NESHAP for 
the Printing, Coating, and Dyeing of Fabrics and Other Textiles; and 
the NESHAP for the Surface Coating of Metal Furniture. The EPA is 
proposing to find the risks due to emissions of air toxics from these 
source categories under the current standards to be acceptable and that 
the standards provide an ample margin of safety to protect public 
health. We are proposing no revisions to the numerical emission limits 
based on these risk analyses or technology reviews. The EPA is 
proposing no new requirements based on the technology review of the 
NESHAP for the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles. The EPA is proposing to require the use of high efficiency 
spray application equipment under the technology review for the two 
rules that employ the use of coating spray application, the NESHAP for 
the Surface Coating of Large Appliances and the NESHAP for the Surface 
Coating of Metal Furniture, if the source is not using the emission 
rate with add-on control compliance option. The EPA is also requesting 
comment on whether the high efficiency spray equipment technology 
requirement under the technology review is necessary in light of the 
risk analyses indicating that there are ample margins of safety. The 
EPA also is proposing to amend provisions addressing emissions during 
periods of startup, shutdown, and malfunction; to amend provisions 
regarding electronic reporting of performance test results; and to make 
miscellaneous clarifying and technical corrections.

DATES: 
    Comments. Comments must be received on or before October 29, 2018.

I. General Information

A. Does this action apply to me?

    Table 1 of this preamble lists the NESHAP and associated regulated 
industrial source categories that are the subject of this proposal. 
Table 1 is not intended to be exhaustive, but rather provides a guide 
for readers regarding the entities that this proposed action is likely 
to affect. The proposed standards, once promulgated, will be directly 
applicable to the affected sources. Federal, state, local, and tribal 
government entities would not be affected by this proposed action. As 
defined in the Initial List of Categories of Sources Under Section 
112(c)(1) of the Clean Air Act Amendments of 1990 (see 57 FR 31576, 
July 16, 1992) and Documentation for Developing the Initial Source 
Category List, Final Report (see EPA-450/3-91-030, July 1992), which 
provides broad descriptions of the categories of major sources included 
on the initial list, the Surface Coating of Large Appliances source 
category includes any facility engaged in the surface coating of any 
large appliance part or product. The category includes, but is not 
limited to, coating of the following large, metal appliance parts or 
products: ranges, conventional ovens, microwave ovens, refrigerators, 
freezers, washers, dryers, dishwashers, water heaters or trash 
compactors manufactured for household, commercial, or recreational use. 
Facilities in this source category are also major sources of HAP 
emissions. We estimate that 10 major source facilities engaged in large 
appliance surface coating would be subject to this proposal. The 
Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category includes any facility engaged in those operations. In fabric 
printing, a decorative pattern or design is applied to fabric by 
methods such as roller, flat screen, or rotary screen. Fabric coating 
is an operation that imparts to a textile substrate, additional 
properties such as strength, stability, water or acid repellency, or 
other specific characteristics of appearance. Fabric dyeing is the 
process in which color is added to a substrate. This category includes, 
but is not limited to, coating of industrial and electrical tapes, tire 
cord, utility meter seals, imitation leathers, tarpaulins, shoe 
material, and upholstery fabrics. We estimate that 43 major source 
facilities engaged in the printing, coating, and dyeing of fabrics and 
other textiles would be subject to this proposal. The Surface Coating 
of Metal Furniture source category includes any facility engaged in the 
surface coating and manufacture of metal furniture parts or products. 
Such products may include chairs, tables, cabinets and bookcases. We 
estimate that 16 major source facilities engaged in metal furniture 
surface coating would be subject to this proposal.

II. Background

A. What is the statutory authority for this action?

    The statutory authority for this action is provided by sections 112 
and 301 of the Clean Air Act (CAA), as amended (42 U.S.C. 7401 et 
seq.).\1\ Section 112 of the CAA establishes a two-stage regulatory 
process to develop standards for emissions of hazardous air pollutants 
(HAP) from stationary sources. Generally, the first stage involves 
establishing technology-based standards and the second stage involves 
evaluating those standards that are based on maximum achievable control 
technology (MACT) to determine whether additional standards are needed 
to further address any remaining risk associated with HAP emissions. 
This second stage is commonly referred to as the ``residual risk 
review.'' In addition to the residual risk review, the CAA also 
requires the EPA to review standards set under CAA section 112 every 
eight years to determine if there are ``developments in practices, 
processes, or control technologies'' that may be appropriate to 
incorporate into the standards. This review is commonly referred to as 
the ``technology review.'' When the two reviews are combined into a 
single rulemaking, it is commonly

[[Page 46266]]

referred to as the ``risk and technology review.'' The discussion that 
follows identifies the most relevant statutory sections and briefly 
explains the contours of the methodology used to implement these 
statutory requirements. A more comprehensive discussion appears in the 
document titled CAA Section 112 Risk and Technology Reviews: Statutory 
Authority and Methodology in the dockets for each subpart in this 
rulemaking.
---------------------------------------------------------------------------

    \1\ In addition, section 301 of the CAA provides general 
authority for the Administrator to ``prescribe such regulations as 
are necessary to carry out his functions'' under the Act.
---------------------------------------------------------------------------

    In the first stage of the CAA section 112 standard setting process, 
the EPA promulgates technology-based standards under CAA section112(d) 
for categories of sources identified as emitting one or more of the HAP 
listed in CAA section 112(b). Sources of HAP emissions are either major 
sources or area sources, and CAA section 112 establishes different 
requirements for major source standards and area source standards. 
``Major sources'' are those that emit or have the potential to emit 10 
tons per year (tpy) or more of a single HAP or 25 tpy or more of any 
combination of HAP. All other sources are ``area sources.'' For major 
sources, CAA section 112(d) provides that the technology-based NESHAP 
must reflect the maximum degree of emission reductions of HAP 
achievable (after considering cost, energy requirements, and non-air 
quality health and environmental impacts). These standards are commonly 
referred to as MACT standards. CAA section 112(d)(3) also establishes a 
minimum control level for MACT standards, known as the MACT ``floor.'' 
The EPA must also consider control options that are more stringent than 
the floor. Standards more stringent than the floor are commonly 
referred to as beyond-the-floor standards. In certain instances, as 
provided in CAA section 112(h), the EPA may set work practice standards 
where it is not feasible to prescribe or enforce a numerical emission 
standard. For area sources, CAA section 112(d)(5) gives the EPA 
discretion to set standards based on generally available control 
technologies or management practices (GACT standards) in lieu of MACT 
standards.
    The second stage in standard-setting focuses on identifying and 
addressing any remaining (i.e., ``residual'') risk according to CAA 
section 112(f). Section 112(f)(2) of the CAA requires the EPA to 
determine for source categories subject to MACT standards whether 
promulgation of additional standards is needed to provide an ample 
margin of safety to protect public health or to prevent an adverse 
environmental effect. Section 112(d)(5) of the CAA provides that this 
residual risk review is not required for categories of area sources 
subject to GACT standards. Section 112(f)(2)(B) of the CAA further 
expressly preserves the EPA's use of the two-step approach for 
developing standards to address any residual risk and the Agency's 
interpretation of ``ample margin of safety'' developed in the National 
Emissions Standards for Hazardous Air Pollutants: Benzene Emissions 
from Maleic Anhydride Plants, Ethylbenzene/Styrene Plants, Benzene 
Storage Vessels, Benzene Equipment Leaks, and Coke By-Product Recovery 
Plants (Benzene NESHAP) (54 FR 38044, September 14, 1989). The EPA 
notified Congress in the Risk Report that the Agency intended to use 
the Benzene NESHAP approach in making CAA section 112(f) residual risk 
determinations (EPA-453/R-99-001, p. ES-11). The EPA subsequently 
adopted this approach in its residual risk determinations and the 
United States Court of Appeals for the District of Columbia Circuit 
(the Court) upheld the EPA's interpretation that CAA section 112(f)(2) 
incorporates the approach established in the Benzene NESHAP. See NRDC 
v. EPA, 529 F.3d 1077, 1083 (DC Cir. 2008).
    The approach incorporated into the CAA and used by the EPA to 
evaluate residual risk and to develop standards under CAA section 
112(f)(2) is a two-step approach. In the first step, the EPA determines 
whether risks are acceptable. This determination ``considers all health 
information, including risk estimation uncertainty, and includes a 
presumptive limit on maximum individual lifetime [cancer] risk (MIR) 
\2\ of approximately [1-in-10 thousand] [i.e., 100-in-1 million].'' 54 
FR 38045, September 14, 1989. If risks are unacceptable, the EPA must 
determine the emissions standards necessary to bring risks to an 
acceptable level without considering costs. In the second step of the 
approach, the EPA considers whether the emissions standards provide an 
ample margin of safety ``in consideration of all health information, 
including the number of persons at risk levels higher than 
approximately [1-in-1 million], as well as other relevant factors, 
including costs and economic impacts, technological feasibility, and 
other factors relevant to each particular decision.'' Id. The EPA must 
promulgate emission standards necessary to provide an ample margin of 
safety to protect public health. After conducting the ample margin of 
safety analysis, we consider whether a more stringent standard is 
necessary to prevent, taking into consideration costs, energy, safety, 
and other relevant factors, an adverse environmental effect.
---------------------------------------------------------------------------

    \2\ Although defined as ``maximum individual risk,'' MIR refers 
only to cancer risk. MIR, one metric for assessing cancer risk, is 
the estimated risk if an individual were exposed to the maximum 
level of a pollutant for a lifetime.
---------------------------------------------------------------------------

    CAA section 112(d)(6) separately requires the EPA to review 
standards promulgated under CAA section 112 and revise them ``as 
necessary (taking into account developments in practices, processes, 
and control technologies)'' no less frequently than every eight years. 
In conducting this review, which we call the ``technology review,'' the 
EPA is not required to recalculate the MACT floor. Natural Resources 
Defense Council (NRDC) v. EPA, 529 F.3d 1077, 1084 (D.C. Cir. 2008). 
Association of Battery Recyclers, Inc. v. EPA, 716 F.3d 667 (D.C. Cir. 
2013). The EPA may consider cost in deciding whether to revise the 
standards pursuant to CAA section 112(d)(6).

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

1. What is the Surface Coating of Large Appliances source category and 
how does the current NESHAP regulate its HAP emissions?
a. Source Category Description
    The NESHAP for the Surface Coating of Large Appliances source 
category was promulgated on July 23, 2002 (67 FR 48254), and codified 
at 40 CFR part 63, subpart NNNN. As promulgated in 2002, the Surface 
Coating of Large Appliances NESHAP applies to the surface coating and 
related operations at each new and existing affected source of HAP 
emissions at facilities that are major sources and are engaged in the 
surface coating of a large appliance part or product. 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'' including, but not limited to, 
``cooking equipment; refrigerators, freezers, and refrigerated cabinets 
and cases; laundry equipment; dishwashers, trash compactors, and water 
heaters; and heating, ventilation, and air-conditioning (HVAC) units, 
air-conditioning (except motor vehicle) units, air-conditioning and 
heating combination units, comfort furnaces, and electric heat pumps. 
Specifically excluded are heat transfer coils and large commercial and 
industrial chillers.''
    Based on our search of the National Emission Inventory (NEI) 
(www.epa.gov/air-emissions-inventories/national-emissions-inventory-nei) and the EPA's

[[Page 46267]]

Enforcement and Compliance History Online (ECHO) database 
(www.echo.epa.gov) and a review of active air emissions permits, we 
estimate that ten facilities are subject to the Surface Coating of 
Large Appliances NESHAP. A complete list of facilities subject to the 
Surface Coating of Large Appliances NESHAP is available in Table 1 of 
Appendix 10 to the memorandum titled Residual Risk Assessment for the 
Surface Coating of Large Appliances Source Category in Support of the 
May 2018 Risk and Technology Review Proposed Rule (hereafter referred 
to as the Large Appliances Risk Assessment Report) in the Large 
Appliances Docket (Docket ID No. EPA-HQ-OAR-2017-0670). The Surface 
Coating of Large Appliances NESHAP also defines a coating as a 
``material that is applied to a substrate for decorative, protective or 
functional purposes. Such materials include, but are not limited to, 
paints, sealants, caulks, inks, adhesives, and maskants. Decorative, 
protective, or functional materials that consist only of protective 
oils, acids, bases, or any combination of these substances are not 
considered coatings for the purposes of this subpart.''
b. HAP Emission Sources
    The primary HAP emitted from large appliance surface coating 
operations are organic HAP and include xylene, glycol ethers, toluene, 
methanol, ethyl benzene, methylene chloride, and methyl isobutyl ether. 
Approximately 80 percent of the HAP emissions from the Surface Coating 
of Large Appliances source category occur from the coating operations 
and from the mixing and storage areas. At the time of the original rule 
promulgation in 2002, most large appliance coating was applied either 
by using a spray gun in a spray booth or by dipping the substrate in a 
tank. Inorganic HAP emissions were considered in the development of the 
Surface Coating of Large Appliances NESHAP. Inorganic HAP, including 
chromium, cobalt, lead, and manganese compounds, are components of some 
specialty coatings used by this source category. However, most of the 
inorganic HAP components remain as solids in the dry coating film on 
the parts being coated or are deposited onto the walls, floor, and 
grates of the spray booths in which they are applied. The remaining 
inorganic HAP particles are entrained in the spray booth exhaust air. 
Spray booths in the large appliance industry typically have either 
water curtains or dry filters to remove overspray particles from the 
exhaust air. No inorganic HAP were reported in the cleaning materials 
in the data collected to develop the Surface Coating of Large 
Appliances NESHAP. No inorganic HAP were reported in the NEI data used 
for this RTR for surface coating operations at major source large 
appliance manufacturing facilities.
c. NESHAP Requirements for Control of HAP
    We estimated that the Surface Coating of Large Appliances NESHAP 
requirements would reduce the emissions of organic HAP from the source 
category by 45 percent or 1,191 tons per year (67 FR 48259, July 23, 
2002). The 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 existing 
sources three compliance options: (1) Compliant coatings i.e., all 
coatings have less than or equal to 0.13 kg organic HAP/liter (1.1 
pound/gallon (lb/gal)) of coating solids; (2) emission rate without 
add-on controls; or (3) emission rate with add-on controls.
    For any coating operation(s) on which the facility uses the 
compliant material option or the emission rate without add-on controls 
option, the facility is not required to meet any work practice 
standards.
    If the facility uses the emission rate with add-on controls option, 
the facility must develop and implement a work practice plan to 
minimize organic HAP emissions from the storage, mixing, and conveying 
of coatings, thinners, and cleaning materials used in, and waste 
materials generated by, the coating operation(s) using that option. The 
plan must specify practices and procedures to ensure that a set of 
minimum work practices specified in the NESHAP are implemented. The 
facility must also 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?
a. Source Category Description
    The NESHAP for the Printing, Coating, and Dyeing of Fabrics and 
Other Textiles source category was promulgated on May 29, 2003 (68 FR 
32172), and codified at 40 CFR part 63, subpart OOOO. As promulgated in 
2003, the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP applies to the printing, coating, slashing, dyeing, or finishing 
of fabrics and other textiles and related operations at each new and 
existing affected source of HAP emissions at facilities that are major 
sources and are engaged in the printing, coating, slashing, dyeing, or 
finishing of fabrics and other textiles. 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. This 
term includes material made of fiberglass, natural fibers, synthetic 
fibers, or composite. The NESHAP 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.
    Based on our search of the NEI and EPA's ECHO database and a review 
of active air emission permits, we estimate that 43 facilities are 
subject to the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP. A complete list of facilities we identified as subject 
to the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP is available in Table 1 of Appendix 10 to the memorandum titled 
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) hereafter referred to as the 
Fabrics and Other Textiles Risk Assessment Report), in the Fabrics and 
Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668).
    The Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP also defines a coating material as an elastomer, polymer, or 
prepolymer material applied as a thin layer to a textile web. Such 
materials include, but are not limited to, coatings, sealants, inks, 
and adhesives. Decorative, protective, or functional materials that 
consist only of acids, bases, or any combination of these substances 
are not considered coating materials for the purposes of this subpart. 
Thinning materials also are not included in this

[[Page 46268]]

definition of coating materials but are accounted for separately.
b. HAP Emission Sources
    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.
    Inorganic HAP emissions were considered in the development of the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP. 
Based on information reported in survey responses during the 
development of the 2002 proposed NESHAP, inorganic HAP, including 
chromium, cobalt, hydrogen chloride (HCl), lead, manganese compounds, 
and nickel were components of some coatings, dyes, and finishes used by 
this source category. However, we concluded that inorganic HAP are not 
likely to be emitted from these sources because of the application 
techniques used (67 FR 46032, July 11, 2002). No inorganic HAP were 
reported in the NEI data used for this RTR for printing, coating, and 
dyeing of fabrics and other textiles operations at major source 
facilities.
c. NESHAP Requirements for Control of HAP
    We estimated that the Printing, Coating, and Dyeing of Fabrics and 
Other Textiles NESHAP requirements would reduce the emissions of 
organic HAP from the source category by 60 percent or 4,100 tpy (68 FR 
32172, May 29, 2003). The NESHAP specifies numerical emission limits 
for organic HAP emissions from three subcategories of surface coating 
application operations: Printing and coating; dyeing and finishing; and 
slashing. The organic HAP emission limit for existing printing or 
coating affected sources is 0.12 kg organic HAP/kg (lb/lb) of coating 
solids applied and for new or reconstructed affected sources is 0.08 kg 
organic HAP/kg (lb/lb) of coating solids applied. Printing or coating 
affected sources may also demonstrate compliance by achieving at least 
a 98-percent HAP reduction for new affected sources or a 97-percent HAP 
reduction for existing sources. New and existing sources using a 
thermal oxidizer may also comply 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 emission limit for conducting dyeing operations is 
0.016 kg organic HAP/kg (lb/lb) dyeing materials applied; the limit for 
conducting finishing operations is 0.0003 kg organic HAP/kg (lb/lb) 
finishing materials applied; and the 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 one percent by weight is counted as zero).
    For any coating, printing, or dyeing operation(s) on which the 
facility uses the compliant material option or the emission rate 
without add-on controls option, the facility is not required to meet 
any work practice standards.
    If the facility uses an add-on control device to demonstrate 
compliance, the facility must develop and implement a work practice 
plan to minimize organic HAP emissions from the storage, mixing, and 
conveying of coatings, thinners, and cleaning materials used in, and 
waste materials generated by, the coating operation(s) using that 
option. The plan must specify practices and procedures to ensure that a 
set of minimum work practices specified in the NESHAP are implemented. 
The facility must also 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?
a. Source Category Description
    The NESHAP for the Surface Coating of Metal Furniture source 
category was promulgated on May 23, 2003 (68 FR 28606), and codified at 
40 CFR part 63, subpart RRRR. As promulgated in 2003, the Surface 
Coating of Metal Furniture NESHAP applies to the surface coating and 
related operations at each new and existing affected source of HAP 
emissions at facilities that are major sources and are engaged, 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. Metal furniture includes, but 
is not limited to, components of the following types of products as 
well as the products themselves: Household, office, institutional, 
laboratory, hospital, public building, restaurant, barber and beauty 
shop, and dental furniture; office and store fixtures; partitions; 
shelving; lockers; lamps and lighting fixtures; and wastebaskets.
    Based on our search of the NEI and the EPA's ECHO database and a 
review of active air emission permits, we estimate that 16 facilities 
are subject to the Surface Coating of Metal Furniture NESHAP. A 
complete list of facilities subject to the Surface Coating of Metal 
Furniture NESHAP is available in Table 1 of Appendix 10 to the 
memorandum titled Residual Risk Assessment for the Surface Coating of 
Metal Furniture Source Category in Support of the May 2018 Risk and 
Technology Review Proposed Rule (hereafter referred to as the Metal 
Furniture Risk Assessment Report), in the Metal Furniture Docket 
(Docket ID No. EPA-HQ-OAR-2017-0669). The Surface Coating of Metal 
Furniture NESHAP defines a coating as a ``material that is applied to a 
substrate for decorative, protective, or functional purposes. Such 
materials include, but are not limited to, paints, sealants, caulks, 
inks, adhesives, and maskants.''
b. HAP Emission Sources
    Most of the organic HAP emissions from metal furniture surface 
coating operations occur from the coating application operations and 
the drying and curing ovens. In most cases, HAP emissions from surface 
preparation, storage, and handling are relatively small for this source 
category. The primary organic HAP emitted from metal furniture surface 
coating operations are xylene, glycol ethers, ethylbenzene, toluene, 
and cumene. These compounds account for more than 95 percent of this 
category's nationwide organic HAP emissions from major sources.
    Inorganic HAP emissions, such as chromium, lead, and manganese 
compounds, were considered in the development of the Surface Coating of 
Metal Furniture NESHAP, and the EPA determined that inorganic HAP 
emissions would be very low (67 FR 20206, April 24, 2002). At that 
time, approximately 680 coatings were reported in the survey responses 
from the metal furniture industry, and only two coatings were reported 
as containing inorganic HAP. In the NEI data used for this risk and 
technology review, only one facility reported inorganic HAP emissions 
(antimony, 0.015 tpy, and nickel, 0.003 tpy) from metal furniture 
surface coating operations. According to the reporting facility, the 
reported emissions in the

[[Page 46269]]

NEI were conservatively over-estimated by an approximate factor of 
10.\3\

Marley Ayres, Pinnacle Engineering, February 7, 2018.
---------------------------------------------------------------------------

c. NESHAP Requirements for Control of HAP
    We estimated the Surface Coating of Metal Furniture NESHAP 
requirements would reduce the emissions of organic HAP from the source 
category by 73 percent or 16,300 tpy (68 FR 28606, May 23, 2003). The 
NESHAP specifies numerical emission limits for organic HAP emissions 
from surface coating application operations. The organic HAP emission 
rate for existing sources is no more than 0.10 kg organic HAP/liter 
(0.83 lb/gal) of coating solids used during each compliance period. A 
new or reconstructed affected source can emit no organic HAP during any 
compliance period unless a source requests approval from the 
Administrator to use an alternative new source emission limit for 
specific metal furniture components or types of components.
    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 emission rate of less than or equal to 0.10 kg organic HAP/
liter (0.83 lb/gal) coating solids used.
    For any metal furniture coating operation(s) on which the facility 
uses the compliant material option or the emission rate without add-on 
controls option, the facility is not required to meet any work practice 
standards.
    If the facility uses an add-on control device to demonstrate 
compliance, the facility must develop and implement a work practice 
plan to minimize organic HAP emissions from the storage, mixing, and 
conveying of coatings, thinners, and cleaning materials used in, and 
waste materials generated by, the coating operation(s) using that 
option. The plan must specify practices and procedures to ensure that a 
set of minimum work practices specified in the NESHAP are implemented. 
The facility must also comply with site-specific operating limits for 
the emission capture and control system.

C. What data collection activities were conducted to support this 
action?

    For the risk modeling portion of these RTRs, the EPA used data from 
the 2011 and 2014 NEI. The NEI is a database that contains information 
about sources that emit criteria air pollutants, their precursors, and 
HAP. The database includes estimates of annual air pollutant emissions 
from point, nonpoint, and mobile sources in the 50 states, the District 
of Columbia, Puerto Rico, and the Virgin Islands. The EPA collects this 
information and releases an updated version of the NEI database every 
three years. The NEI includes data necessary for conducting risk 
modeling, including annual HAP emissions estimates from individual 
emission points at facilities and the related emissions release 
parameters. We used NEI emissions and supporting data as the primary 
data to develop the model input files for the risk assessments for each 
of these three source categories. Additional information on the 
development of the modeling file for each source category can be found 
in Appendix 1 to the Large Appliances Risk Assessment Report in the 
Large Appliances Docket (Docket ID No. EPA-HQ-OAR-2017-0670), Appendix 
1 to the Fabrics and Other Textiles Risk Assessment Report in the 
Fabrics and Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668), 
and Appendix 1 to the Metal Furniture Risk Assessment Report in the 
Metal Furniture Docket (Docket ID No. EPA-HQ-OAR-2017-0669).
    For both the risk modeling and technology review portion of these 
RTRs, we also gathered data from facility construction and operating 
permits, regarding emission points, air pollution control devices, and 
process operations. We collected permits and supporting documentation 
from state permitting authorities through state-maintained online 
databases. The facility permits were also used to confirm that the 
facilities were major sources of HAP and were subject to the NESHAP 
that are the subject of these risk assessments. In certain cases, we 
contacted facility owners or operators to confirm and clarify the 
sources of emissions that were reported in the NEI. No formal 
information collection request was performed.
    For the technology review portion of these RTRs, we also used 
information from the EPA's ECHO database as a tool to identify which 
facilities were potentially subject to the NESHAP. The ECHO database 
provides integrated compliance and enforcement information for 
approximately 800,000 regulated facilities nationwide. Using the search 
feature in ECHO, the EPA identified facilities that could potentially 
be subject to each of these three NESHAP. We then reviewed operating 
permits for these facilities, when available, to confirm that they were 
major sources of HAP with emission sources subject to these NESHAP.
    Also for the technology reviews, we collected information from the 
Reasonably Available Control Technology (RACT), Best Available Control 
Technology (BACT), and Lowest Achievable Emission Rate (LAER) 
determinations in the EPA's RACT/BACT/LAER Clearinghouse (RBLC).\4\ 
This is a database that contains case-specific information on air 
pollution technologies that have been required to reduce the emissions 
of air pollutants from stationary sources. Under the EPA's New Source 
Review (NSR) program, if a facility is planning new construction or a 
modification that will increase the air emissions by a large amount, an 
NSR permit must be obtained. This central database promotes the sharing 
of information among permitting agencies and aids in case-by-case 
determinations for NSR permits. We examined information contained in 
the RBLC to determine what technologies are currently used for these 
surface coating operations to reduce air emissions.

    Additional information about these data collection activities for 
the technology reviews is contained in the technology review memoranda 
titled Technology Review for Surface Coating Operations in the Large 
Appliance Category, August 2017 (hereafter referred to as the Large 
Appliances Technology Review Memo), Technology Review for Printing, 
Coating, and Dyeing Category, August 2017 (hereafter referred to as the 
Fabrics and Other Textiles Technology Review Memo), and Technology 
Review for Surface Coating Operations in the Metal Furniture Category, 
September 2017 (hereafter referred to as the Metal Furniture Technology 
Review Memo), available respectively in the Large Appliances Docket, 
Fabrics and Other Textiles Docket, and Metal Furniture Docket.

D. What other relevant background information and data are available?

    For the technology review for each source category, we reviewed the 
NESHAP for various industries that were promulgated since the MACT 
standards being reviewed in this action.

[[Page 46270]]

We reviewed the regulatory requirements and/or technical analyses 
associated with these later regulatory actions to identify any 
practices, processes, and control technologies considered in those 
rulemakings that could be applied to emission sources in each of these 
three source categories, as well as the costs, non-air impacts, and 
energy implications associated with the use of those technologies. We 
also reviewed information available in the American Coatings 
Association's (ACA) Industry Market Analysis, 9th Edition (2014-
2019),\5\ for the Surface Coating of Metal Furniture and Surface 
Coating of Large Appliances source categories. The ACA Industry Market 
Analysis provided information on trends in coatings technology that can 
affect emissions from the metal furniture and large appliance source 
categories, but did not address the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles source category. Additional details 
regarding our review of these information sources are contained in the 
Large Appliances Technology Review Memo, the Fabrics and Other Textiles 
Technology Review Memo, and the Metal Furniture Technology Review Memo, 
available in the Large Appliances Docket, Fabrics and Other Textiles 
Docket, and Metal Furniture Docket, respectively.

III. Analytical Procedures

    In this section, we describe the analyses performed to support the 
proposed decisions for the RTRs and other issues addressed in this 
proposal.

A. How do we consider risk in our decision-making?

    As discussed in section II.A of this preamble and in the Benzene 
NESHAP, in evaluating and developing standards under CAA section 
112(f)(2), we apply a two-step approach to determine whether or not 
risks are acceptable and to determine if the standards provide an ample 
margin of safety to protect public health. As explained in the Benzene 
NESHAP, ``the first step judgment on acceptability cannot be reduced to 
any single factor'' and, thus, ``[t]he Administrator believes that the 
acceptability of risk under section 112 is best judged on the basis of 
a broad set of health risk measures and information.'' 54 FR 38046, 
September 14, 1989. Similarly, with regard to the ample margin of 
safety determination, ``the Agency again considers all of the health 
risk and other health information considered in the first step. Beyond 
that information, additional factors relating to the appropriate level 
of control will also be considered, including cost and economic impacts 
of controls, technological feasibility, uncertainties, and any other 
relevant factors.'' Id.
    The Benzene NESHAP approach provides flexibility regarding factors 
the EPA may consider in making determinations and how the EPA may weigh 
those factors for each source category. The EPA conducts a risk 
assessment that provides estimates of the MIR posed by the HAP 
emissions from each source in the source category, the hazard index 
(HI) for chronic exposures to HAP with the potential to cause noncancer 
health effects, and the hazard quotient (HQ) for acute exposures to HAP 
with the potential to cause noncancer health effects.\6\ The assessment 
also provides estimates of the distribution of cancer risks within the 
exposed populations, cancer incidence, and an evaluation of the 
potential for adverse environmental effects. The scope of EPA's risk 
analysis is consistent with EPA's response to comments on our policy 
under the Benzene NESHAP where the EPA explained that:
---------------------------------------------------------------------------

    \6\ The MIR is defined as the cancer risk associated with a 
lifetime of exposure at the highest concentration of HAP where 
people are likely to live. The HQ is the ratio of the potential 
exposure to the HAP to the level at or below which no adverse 
chronic noncancer effects are expected; the HI is the sum of HQs for 
HAP that affect the same target organ or organ system.
---------------------------------------------------------------------------

    ``[t]he policy chosen by the Administrator permits consideration of 
multiple measures of health risk. Not only can the MIR figure be 
considered, but also incidence, the presence of noncancer health 
effects, and the uncertainties of the risk estimates. In this way, the 
effect on the most exposed individuals can be reviewed as well as the 
impact on the general public. These factors can then be weighed in each 
individual case. This approach complies with the Vinyl Chloride mandate 
that the Administrator ascertain an acceptable level of risk to the 
public by employing his expertise to assess available data. It also 
complies with the Congressional intent behind the CAA, which did not 
exclude the use of any particular measure of public health risk from 
the EPA's consideration with respect to CAA section 112 regulations, 
and thereby implicitly permits consideration of any and all measures of 
health risk which the Administrator, in his judgment, believes are 
appropriate to determining what will `protect the public health'.'' See 
54 FR 38057, September 14, 1989.
    Thus, the level of the MIR is only one factor to be weighed in 
determining acceptability of risks. The Benzene NESHAP explained that 
``an MIR of approximately one in ten thousand should ordinarily be the 
upper end of the range of acceptability. As risks increase above this 
benchmark, they become presumptively less acceptable under CAA section 
112, and would be weighed with the other health risk measures and 
information in making an overall judgment on acceptability. Or, the 
Agency may find, in a particular case, that a risk that includes MIR 
less than the presumptively acceptable level is unacceptable in the 
light of other health risk factors.'' Id. at 38045. Similarly, with 
regard to the ample margin of safety analysis, the EPA stated in the 
Benzene NESHAP that: ``EPA believes the relative weight of the many 
factors that can be considered in selecting an ample margin of safety 
can only be determined for each specific source category. This occurs 
mainly because technological and economic factors (along with the 
health-related factors) vary from source category to source category.'' 
Id. at 38061. We also consider the uncertainties associated with the 
various risk analyses, as discussed earlier in this preamble, in our 
determinations of acceptability and ample margin of safety.
    The EPA notes that it has not considered certain health information 
to date in making residual risk determinations. At this time, we do not 
attempt to quantify those HAP risks that may be associated with 
emissions from other facilities that do not include the source 
categories under review, mobile source emissions, natural source 
emissions, persistent environmental pollution, or atmospheric 
transformation in the vicinity of the sources in the categories.
    The EPA understands the potential importance of considering an 
individual's total exposure to HAP in addition to considering exposure 
to HAP emissions from the source category and facility. We recognize 
that such consideration may be particularly important when assessing 
noncancer risks, where pollutant-specific exposure health reference 
levels (e.g., reference concentrations (RfCs)) are based on the 
assumption that thresholds exist for adverse health effects. For 
example, the EPA recognizes that, although exposures attributable to 
emissions from a source category or facility alone may not indicate the 
potential for increased risk of adverse noncancer health effects in a 
population, the exposures resulting from emissions from the facility in 
combination with emissions from all of

[[Page 46271]]

the other sources (e.g., other facilities) to which an individual is 
exposed may be sufficient to result in increased risk of adverse 
noncancer health effects. In May 2010, the Science Advisory Board (SAB) 
advised the EPA ``that RTR assessments will be most useful to decision 
makers and communities if results are presented in the broader context 
of aggregate and cumulative risks, including background concentrations 
and contributions from other sources in the area.'' \7\
---------------------------------------------------------------------------

    \7\ The EPA's responses to this and all other key 
recommendations of the SAB's advisory on RTR risk assessment 
methodologies (which is available at: https://yosemite.epa.gov/sab/
sabproduct.nsf/4AB3966E263D943A8525771F00668381/$File/EPA-SAB-10-
007-unsigned.pdf) are outlined in a memorandum to this rulemaking 
docket from David Guinnup titled EPA's Actions in Response to the 
Key Recommendations of the SAB Review of RTR Risk Assessment 
Methodologies.
---------------------------------------------------------------------------

    In response to the SAB recommendations, the EPA is incorporating 
certain cumulative risk analyses into its RTR risk assessments, 
including those reflected in this proposal. Specifically, the Agency is 
(1) conducting facility-wide assessments, which include source category 
emission points, as well as other emission points within the 
facilities; (2) combining exposures from multiple sources in the same 
category that could affect the same individuals; and (3) for some 
persistent and bioaccumulative pollutants, analyzing the ingestion 
route of exposure. In addition, the RTR risk assessments have always 
considered aggregate cancer risk from all carcinogens and aggregate 
noncancer HI from all noncarcinogens affecting the same target organ 
system.
    Although we look at the cumulative risks from all sources at 
facilities within the category, we do not assess the cumulative risks 
from facilities outside the category that may be in the vicinity. We 
are interested in placing source category and facility-wide HAP risks 
in the context of total HAP risks from all sources of HAP in the 
vicinity of each source. However, because of the contribution to total 
HAP risk from emission sources other than those that we have studied, 
in depth, during this RTR review, such estimates of total HAP risks 
would have significantly greater associated uncertainties than the 
source category or facility-wide estimates. Such aggregate or 
cumulative assessments would compound those uncertainties, making the 
assessments too unreliable.

B. How do we perform the technology review?

    Our technology reviews focus on the identification and evaluation 
of developments in practices, processes, and control technologies that 
have occurred since the MACT standards were promulgated. Where we 
identify such developments, in order to inform our decision of whether 
it is ``necessary'' to revise the emissions standards, we analyze the 
technical feasibility of applying these developments and the estimated 
costs, energy implications, and non-air environmental impacts, and we 
also consider the emission reductions. In addition, we consider the 
appropriateness of applying controls to future affected sources versus 
retrofitting affected sources currently subject to the NESHAP.
    For this exercise, we consider any of the following to be a 
``development'':
     Any add-on control technology or other equipment that was 
not identified and considered during development of the original MACT 
standards;
     Any improvements in add-on control technology or other 
equipment (that were identified and considered during development of 
the original MACT standards) that could result in additional emissions 
reduction;
     Any work practice or operational procedure that was not 
identified or considered during development of the original MACT 
standards;
     Any process change or pollution prevention alternative 
that could be broadly applied to the industry and that was not 
identified or considered during development of the original MACT 
standards; and
     Any significant changes in the cost (including cost 
effectiveness) of applying controls (including controls the EPA 
considered during the development of the original MACT standards).
    In addition to reviewing the practices, processes, and control 
technologies that were considered at the time we originally developed 
the NESHAP (i.e., the 2002 Surface Coating of Large Appliances NESHAP; 
the 2003 Printing, Coating, and Dyeing of Fabrics and Other Textiles 
NESHAP; and the 2003 Surface Coating of Metal Furniture NESHAP), we 
reviewed a variety of data sources in our investigation of potential 
practices, processes, or controls that were not considered for each of 
the three source categories during development of the NESHAP. Among the 
sources we reviewed were the NESHAP for various industries that were 
promulgated since the MACT standards being reviewed in this action 
(e.g., NESHAP for Miscellaneous Metal Parts and Products (40 CFR part 
63, subpart MMMM)). We also reviewed the results of other technology 
reviews for other surface coating source categories since the 
promulgation of the NESHAP (e.g., the technology reviews conducted for 
the Shipbuilding and Ship Repair (Surface Coating) NESHAP (40 CFR part 
63, subpart II) and the Wood Furniture Manufacturing Operations NESHAP 
(40 CFR part 63, subpart JJ)). We reviewed the regulatory requirements 
and/or technical analyses associated with these regulatory actions to 
identify any practices, processes, and control technologies considered 
in these efforts that could be applied to emission sources in the 
Surface Coating of Large Appliances source category, the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category, and 
the Surface Coating of Metal Furniture source category, as well as the 
costs, non-air impacts, and energy implications associated with the use 
of these technologies. Finally, we reviewed information from other 
sources, such as state and/or local permitting agency databases and 
industry-sponsored market analyses and trade journals, searching for 
advancements in add-on controls, advancements in lower HAP technology 
for coatings and solvents. For a more detailed discussion of our 
methods for performing these technology reviews, refer to the Large 
Appliances Technology Review Memo, the Fabrics and Other Textiles 
Technology Review Memo, and the Metal Furniture Technology Review Memo, 
available respectively in the Large Appliances Docket, Fabrics and 
Other Textiles Docket, and Metal Furniture Docket.

C. How did we estimate post-MACT risks posed by these source 
categories?

    The EPA conducted risk assessments that provide estimates of the 
MIR for cancer posed by the HAP emissions from each source in each 
source category, the HI for chronic exposures to HAP with the potential 
to cause noncancer health effects, and the HQ for acute exposures to 
HAP with the potential to cause noncancer health effects. The 
assessments also provide estimates of the distribution of cancer risks 
within the exposed populations, cancer incidence, and an evaluation of 
the potential for adverse environmental effects. The seven sections 
that follow this paragraph describe how we estimated emissions and 
conducted the risk assessments. The Large Appliances Docket, Fabrics 
and Other Textiles Docket, and Metal Furniture Docket contain, 
respectively, the Large Appliances Risk Assessment Report, the Fabrics 
and Other Textiles Risk Assessment Report, and the Metal Furniture Risk 
Assessment Report, which provide more information on the

[[Page 46272]]

risk assessment inputs and models. The methods used to assess risks (as 
described in the seven primary steps below) are consistent with those 
peer-reviewed by a panel of the EPA's SAB in 2009 and described in 
their peer review report issued in 2010; \8\ they are also consistent 
with the key recommendations contained in that report.

Assessment Methodologies: For Review by the EPA's Science Advisory 
Board with Case Studies--MACT I Petroleum Refining Sources and 
Portland Cement Manufacturing, May 2010.
---------------------------------------------------------------------------

1. How did we estimate actual emissions and identify the emissions 
release characteristics?
    The actual emissions and the emission release characteristics for 
each facility were obtained primarily from either the 2011 NEI or the 
2014 NEI. Most data were obtained from the 2011 NEI, unless the 2014 
NEI included HAP data for emission units or processes for which the 
2011 NEI included only volatile organic compounds (VOC) or particulate 
matter. In some cases, the facilities were contacted to confirm 
emissions that appeared to be outliers, that were otherwise 
inconsistent with our understanding of the industry, or that were 
associated with high risk values in our initial risk screening 
analyses. When appropriate, emission values and release characteristics 
were corrected based on these facility contacts, and these changes were 
documented. Additional information on the development of the modeling 
file for each source category, including the development of the actual 
emissions and emissions release characteristics, can be found in 
Appendix 1 to the Large Appliances Risk Assessment Report in the Large 
Appliances Docket, Appendix 1 to the Fabrics and Other Textiles Risk 
Assessment Report in the Fabrics and Other Textiles Docket, and 
Appendix 1 to the Metal Furniture Risk Assessment Report in the Metal 
Furniture Docket.
2. How did we estimate MACT-allowable emissions?
    The available emissions data in the RTR emissions dataset include 
estimates of the mass of HAP emitted during a specified annual time 
period. These ``actual'' emission levels are often lower than the 
emission levels allowed under the requirements of the current MACT 
standards. The emissions level allowed to be emitted under the MACT 
standards is referred to as the ``MACT-allowable'' emissions level. We 
discussed the use of both MACT-allowable and actual emissions in the 
final Coke Oven Batteries RTR (70 FR 19998-19999, April 15, 2005) and 
in the proposed and final Hazardous Organic NESHAP RTRs (71 FR 34428, 
June 14, 2006, and 71 FR 76609, December 21, 2006, respectively). In 
those actions, we noted that assessing the risks at the MACT-allowable 
level is inherently reasonable since these risks reflect the maximum 
level facilities could emit and still comply with national emission 
standards. We also explained that it is reasonable to consider actual 
emissions, where such data are available, in both steps of the risk 
analysis, in accordance with the Benzene NESHAP approach. (54 FR 38044, 
September 14, 1989.)
    For the Surface Coating of Large Appliances source category, the 
EPA calculated allowable emissions by developing a source category-
specific multiplier of 1.2 that was applied to the current emissions to 
estimate allowable emissions. The multiplier was calculated using 
annual coating sales volumes provided in the ACA Industry Market 
Analysis for appliance finishes in the years 2005 to 2014. For more 
information on how the EPA calculated the MACT-allowable emissions for 
the Surface Coating of Large Appliances source category, please see 
Appendix 1 to the Large Appliances Risk Assessment Report in the Large 
Appliances Docket (Docket ID No. EPA-HQ-OAR-2017-0670).
    For the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
source category, the EPA calculated allowable emissions by developing a 
source category-specific multiplier of 1.1 that was applied to the 
current emissions to estimate allowable emissions. We gathered current 
and historical publicly available category-specific production data 
from U.S. Census and based the calculation on plant capacity 
utilization rates for six different NAICS codes related to fabric and 
textile production for the years 2008 to 2016. We assumed the annual 
plant capacity utilization rates represented industry annual production 
rates. The multiplier of 1.1, or the ratio of the peak annual 
utilization rate in 2013 to the average annual utilization rate for the 
years 2008 to 2016, was applied to the actual emissions to estimate 
allowable emissions. For more details on how the EPA calculated the 
MACT-allowable emissions for the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles source category, please see Appendix 1 to 
the Fabrics and Other Textiles Risk Assessment Report in the Fabrics 
and Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668).
    For the Surface Coating of Metal Furniture source category, the EPA 
calculated allowable emissions by developing a source category-specific 
multiplier of 1.8 that was applied to the current emissions to estimate 
allowable emissions. The multiplier was calculated using annual coating 
sales volumes from the ACA Industry Market Analysis for non-wood 
furniture, fixture, and business equipment coatings from 2005 to 2014. 
For more details on how the EPA calculated the MACT-allowable emissions 
for the Surface Coating of Metal Furniture source category, please see 
Appendix 1 to the Metal Furniture Risk Assessment Report in the Metal 
Furniture Docket (Docket ID No. EPA-HQ-OAR-2017-0669).
3. How did we conduct dispersion modeling, determine inhalation 
exposures, and estimate individual and population inhalation risks?
    Both long-term and short-term inhalation exposure concentrations 
and health risks from the source categories addressed in this proposal 
were estimated using the Human Exposure Model (HEM-3). The HEM-3 
performs three primary risk assessment activities: (1) Conducting 
dispersion modeling to estimate the concentrations of HAP in ambient 
air, (2) estimating long-term and short-term inhalation exposures to 
individuals residing within 50 kilometers (km) of the modeled sources, 
and (3) estimating individual and population-level inhalation risks 
using the exposure estimates and quantitative dose-response 
information.
a. Dispersion Modeling
    The air dispersion model AERMOD, used by the HEM-3 model, is one of 
the EPA's preferred models for assessing air pollutant concentrations 
from industrial facilities.\9\ To perform the dispersion modeling and 
to develop the preliminary risk estimates, HEM-3 draws on three data 
libraries. The first is a library of meteorological data, which is used 
for dispersion calculations. This library includes one year (2016) of 
hourly surface and upper air observations from 824 meteorological 
stations, selected to provide coverage of the U.S. and Puerto Rico. A 
second library of U.S. Census Bureau census block \10\ internal point 
locations and populations provides the basis of human exposure 
calculations (U.S. Census, 2010). In addition, for each census block, 
the census library

[[Page 46273]]

includes the elevation and controlling hill height, which are also used 
in dispersion calculations. A third library of pollutant-specific dose-
response values is used to estimate health risks. These dose-response 
values are the latest values recommended by the EPA for HAP. They are 
available at https://www.epa.gov/fera/dose-response-assessment-assessing-health-risks-associated-exposure-hazardous-air-pollutants and 
are discussed in more detail later in this section.

b. Risk From Chronic Exposure to HAP That May Cause Cancer
    In developing the risk assessment for chronic exposures, we used 
the estimated annual average ambient air concentrations of each HAP 
emitted by each source for which we have emissions data in the source 
categories. The air concentrations at each nearby census block centroid 
were used as a surrogate for the chronic inhalation exposure 
concentration for all the people who reside in that census block. We 
calculated the MIR for each facility as the cancer risk associated with 
a continuous lifetime (24 hours per day, seven days per week, 52 weeks 
per year, for a 70-year period) exposure to the maximum concentration 
at the centroid of inhabited census blocks. Individual cancer risks 
were calculated by multiplying the estimated lifetime exposure to the 
ambient concentration of each HAP (in micrograms per cubic meter) by 
its unit risk estimate (URE). The URE is an upper bound estimate of an 
individual's probability of contracting cancer over a lifetime of 
exposure to a concentration of one microgram of the pollutant per cubic 
meter of air. For residual risk assessments, we generally use UREs from 
the EPA's Integrated Risk Information System (IRIS). For carcinogenic 
pollutants without IRIS values, we look to other reputable sources of 
cancer dose-response values, often using California EPA (CalEPA) UREs, 
where available. In cases where new, scientifically credible dose-
response values have been developed in a manner consistent with the EPA 
guidelines and have undergone a peer review process similar to that 
used by the EPA, we may use such dose-response values in place of, or 
in addition to, other values, if appropriate.
    To estimate incremental individual lifetime cancer risks associated 
with emissions from the facilities in the source categories, the EPA 
summed the risks for each of the carcinogenic HAP \11\ emitted by the 
modeled sources. Cancer incidence and the distribution of individual 
cancer risks for the population within 50 km of the sources were also 
estimated for the source category by summing individual risks. A 
distance of 50 km is consistent with both the analysis supporting the 
1989 Benzene NESHAP (54 FR 38044, September 14, 1989) and the 
limitations of Gaussian dispersion models, including AERMOD.
---------------------------------------------------------------------------

    \11\ The EPA classifies carcinogens as: Carcinogenic to humans, 
likely to be carcinogenic to humans, and suggestive evidence of 
carcinogenic potential. These classifications also coincide with the 
terms ``known carcinogen, probable carcinogen, and possible 
carcinogen,'' respectively, which are the terms advocated in the 
EPA's Guidelines for Carcinogen Risk Assessment, published in 1986 
(51 FR 33992, September 24, 1986). In August 2000, the document, 
Supplemental Guidance for Conducting Health Risk Assessment of 
Chemical Mixtures (EPA/630/R-00/002), was published as a supplement 
to the 1986 document. Copies of both documents can be obtained from 
https://cfpub.epa.gov/ncea/risk/recordisplay.cfm?deid=20533&CFID=70315376&CFTOKEN=71597944. Summing 
the risks of these individual compounds to obtain the cumulative 
cancer risks is an approach that was recommended by the EPA's SAB in 
their 2002 peer review of the EPA's National Air Toxics Assessment 
(NATA) titled NATA--Evaluating the National-scale Air Toxics 
Assessment 1996 Data--an SAB Advisory, available at https://
yosemite.epa.gov/sab/sabproduct.nsf/
214C6E915BB04E14852570CA007A682C/$File/ecadv02001.pdf.
---------------------------------------------------------------------------

c. Risk From Chronic Exposure to HAP That May Cause Health Effects 
Other Than Cancer
    To assess the risk of noncancer health effects from chronic 
exposure to HAP, we calculate either an HQ or a target organ-specific 
hazard index (TOSHI). We calculate an HQ when a single noncancer HAP is 
emitted. Where more than one noncancer HAP is emitted, we sum the HQ 
for each of the HAP that affects a common target organ system to obtain 
a TOSHI. The HQ is the estimated exposure divided by the chronic 
noncancer dose-response value, which is a value selected from one of 
several sources. The preferred chronic noncancer dose-response value is 
the EPA RfC (https://iaspub.epa.gov/sor_internet/registry/termreg/searchandretrieve/glossariesandkeywordlists/search.do?details=&vocabName=IRIS%20Glossary), defined as ``an estimate 
(with uncertainty spanning perhaps an order of magnitude) of a 
continuous inhalation exposure to the human population (including 
sensitive subgroups) that is likely to be without an appreciable risk 
of deleterious effects during a lifetime.'' In cases where an RfC from 
the EPA's IRIS database is not available or where the EPA determines 
that using a value other than the RfC is appropriate, the chronic 
noncancer dose-response value can be a value from the following 
prioritized sources, which define their dose-response values similarly 
to EPA: (1) The Agency for Toxic Substances and Disease Registry 
(ATSDR) Minimum Risk Level (https://www.atsdr.cdc.gov/mrls/index.asp); 
(2) the CalEPA Chronic Reference Exposure Level (REL) (https://oehha.ca.gov/air/crnr/notice-adoption-air-toxics-hot-spots-program-guidance-manual-preparation-health-risk-0); or (3), as noted above, a 
scientifically credible dose-response value that has been developed in 
a manner consistent with the EPA guidelines and has undergone a peer 
review process similar to that used by the EPA.
d. Risk From Acute Exposure to HAP That May Cause Health Effects Other 
Than Cancer
    For each HAP for which appropriate acute inhalation dose-response 
values are available, the EPA also assesses the potential health risks 
due to acute exposure. For these assessments, the EPA makes 
conservative assumptions about emission rates, meteorology, and 
exposure location. We use the peak hourly emission rate (when 
available),\12\ worst-case dispersion conditions, and, in accordance 
with our mandate under section 112 of the CAA, the point of highest 
off-site exposure to assess the potential risk to the maximally exposed 
individual.
---------------------------------------------------------------------------

    \12\ In the absence of hourly emission data, we develop 
estimates of maximum hourly emission rates by multiplying the 
average actual annual emissions rates by a factor (either a 
category-specific factor or a default factor of 10) and dividing by 
the total number of hours in a year (8,760 hours) to account for 
variability. This is documented in Large Appliances Risk Assessment 
Report, Fabrics and Other Textiles Risk Assessment Report, and Metal 
Furniture Risk Assessment Report and in Appendix 5 of the report: 
Analysis of Data on Short-term Emission Rates Relative to Long-term 
Emission Rates. These documents are available in the Large 
Appliances Docket, Fabrics and Other Textiles Docket, and Metal 
Furniture Docket.
---------------------------------------------------------------------------

    To characterize the potential health risks associated with 
estimated acute inhalation exposures to a HAP, we generally use 
multiple acute dose-response values, including acute RELs, acute 
exposure guideline levels (AEGLs), and emergency response planning 
guidelines (ERPG) for 1-hour exposure durations), if available, to 
calculate acute HQs. The acute HQ is calculated by dividing the 
estimated acute exposure by the acute dose-response value. For each HAP 
for which acute dose-response values are available, the EPA calculates 
acute HQs.
    An acute REL is defined as ``the concentration level at or below 
which no adverse health effects are anticipated

[[Page 46274]]

for a specified exposure duration.'' \13\ Acute RELs are based on the 
most sensitive, relevant, adverse health effect reported in the peer-
reviewed medical and toxicological literature. They are designed to 
protect the most sensitive individuals in the population through the 
inclusion of margins of safety. Because margins of safety are 
incorporated to address data gaps and uncertainties, exceeding the REL 
does not automatically indicate an adverse health impact. AEGLs 
represent threshold exposure limits for the general public and are 
applicable to emergency exposures ranging from ten minutes to eight 
hours.\14\ They are guideline levels for ``once-in-a-lifetime, short-
term exposures to airborne concentrations of acutely toxic, high-
priority chemicals.'' Id. at 21. The AEGL-1 is specifically defined as 
``the airborne concentration (expressed as ppm (parts per million) or 
mg/m\3\ (milligrams per cubic meter)) of a substance above which it is 
predicted that the general population, including susceptible 
individuals, could experience notable discomfort, irritation, or 
certain asymptomatic nonsensory effects. However, the effects are not 
disabling and are transient and reversible upon cessation of 
exposure.'' The document also notes that ``Airborne concentrations 
below AEGL-1 represent exposure levels that can produce mild and 
progressively increasing but transient and nondisabling odor, taste, 
and sensory irritation or certain asymptomatic, nonsensory effects.'' 
Id. AEGL-2 are defined as ``the airborne concentration (expressed as 
parts per million or milligrams per cubic meter) of a substance above 
which it is predicted that the general population, including 
susceptible individuals, could experience irreversible or other 
serious, long-lasting adverse health effects or an impaired ability to 
escape.'' Id.
---------------------------------------------------------------------------

    \13\ CalEPA issues acute RELs as part of its Air Toxics Hot 
Spots Program, and the 1-hour and 8-hour values are documented in 
Air Toxics Hot Spots Program Risk Assessment Guidelines, Part I, The 
Determination of Acute Reference Exposure Levels for Airborne 
Toxicants, which is available at https://oehha.ca.gov/air/general-info/oehha-acute-8-hour-and-chronic-reference-exposure-level-rel-summary.

Hazardous Substances ended in October 2011, but the AEGL program 
continues to operate at the EPA and works with the National 
Academies to publish final AEGLs, (https://www.epa.gov/aegl).
---------------------------------------------------------------------------

    ERPGs are ``developed for emergency planning and are intended as 
health-based guideline concentrations for single exposures to 
chemicals.'' \15\ Id. at 1. The ERPG-1 is defined as ``the maximum 
airborne concentration below which it is believed that nearly all 
individuals could be exposed for up to one hour without experiencing 
other than mild transient adverse health effects or without perceiving 
a clearly defined, objectionable odor.'' Id. at 2. Similarly, the ERPG-
2 is defined as ``the maximum airborne concentration below which it is 
believed that nearly all individuals could be exposed for up to one 
hour without experiencing or developing irreversible or other serious 
health effects or symptoms which could impair an individual's ability 
to take protective action.'' Id. at 1.

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

    An acute REL for 1-hour exposure durations is typically lower than 
its corresponding AEGL-1 and ERPG-1. Even though their definitions are 
slightly different, AEGL-1s are often the same as the corresponding 
ERPG-1s, and AEGL-2s are often equal to ERPG-2s. The maximum HQs from 
our acute inhalation screening risk assessment typically result when we 
use the acute REL for a HAP. In cases where the maximum acute HQ 
exceeds 1, we also report the HQ based on the next highest acute dose-
response value (usually the AEGL-1 and/or the ERPG-1).
    For these source categories, we did not have short term emissions 
data; therefore, we developed source category-specific factors based on 
information about each industry. We request comment on our assumptions 
regarding hour-to-hour variation in emissions and our methods of 
calculating the multiplier for estimating the peak 1-hour emissions for 
each source category and any additional information that could help 
refine our approach.
    For the Surface Coating of Large Appliances source category, we do 
not expect to see substantial hour-to-hour variation in emissions 
during routine operations because the industry employs the use of 
compliant low HAP coatings in a continuous (non-batch) coating process. 
Thus, applying the default emission factor of ten to estimate the 
worst-case hourly emission rate is not reasonable for this category. We 
expect that minimal variations in emissions could possibly occur due to 
cleaning of process equipment during routine operations for coating 
operations using the emission rate without add-on controls compliance 
option. We calculated worst-case hourly emissions by developing a 
source category-specific multiplier of 1.2 that was applied to the 
annual emissions, which were then divided by the total number of hours 
in a year (8,760 hours). The multiplier was based on historical data on 
coating sales volumes from the ACA Industry Market Analysis for 
appliance finishes 2005 to 2014. The multiplier was the ratio of the 
peak coating sales volume (in gallons) in 2006 to the average sales 
volume for the years 2005 to 2014. The peak coating sales volume in 
2006 was assumed to represent the maximum utilization of the current 
large appliance surface coating industry. A further discussion of why 
this factor was chosen can be found in Appendix 1 to the Large 
Appliances Risk Assessment Report in the Large Appliances Docket.
    For the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
source category, we do not expect to see substantial hour-to-hour 
variation in emissions during routine operations because the industry 
employs the use of various compliance options, including add-on 
controls, compliant low HAP coatings, or emission rate without add-on 
controls option, in a continuous (non-batch) coating process that 
achieve consistent emission rates. Thus, applying the default emission 
factor of ten to estimate the worst-case hourly emission rate is not 
reasonable for this category. We expect that minimal variations in 
emissions could possibly occur during routine operations due to 
cleaning of process equipment. We calculated acute emissions by 
developing a source category-specific multiplier of 1.4 that was 
applied to the annual emissions, which were then divided by the total 
number of hours in a year (8,760 hours). The multiplier was based on 
historical U.S. Census data on plant capacity utilization rates for six 
different NAICS codes related to fabric and textile production for the 
years 2008 to 2016. The multiplier was the ratio of the maximum 
utilization rate (100 percent) to the peak utilization rate of 71.7 
percent for the years 2008 to 2016. A further discussion of why this 
factor was chosen can be found in Appendix 1 to the Fabrics and Other 
Textiles Risk Assessment Report in the Fabrics and Other Textiles 
Docket.
    For the Surface Coating of Metal Furniture source category, we do 
not expect to see substantial hour-to-hour variation in emissions 
during routine operations because the industry employs the use of 
compliant low HAP

[[Page 46275]]

coatings in a continuous (non-batch) coating process. Thus, applying 
the default emission factor of ten to estimate the worst-case hourly 
emission rate is not reasonable for this category. We expect that 
minimal variations in emissions could possibly occur due to cleaning of 
process equipment during routine operations for coating operations 
using the emission rate without add-on controls compliance option. We 
calculated worst-case hourly emissions by developing a source category-
specific multiplier of 1.8 that was applied to the annual emissions, 
which were then divided by the total number of hours in a year (8,760 
hours). The multiplier was based on historical data on coating sales 
volumes from the ACA Industry Market Analysis for non-wood furniture, 
fixture and business equipment coatings from 2005 to 2014. The 
multiplier was the ratio of the peak coating sales volume (in gallons) 
in 2005 to the average sales volume for the years 2005 to 2014. The 
peak sales volume in 2005 was assumed to represent maximum utilization 
of the current metal furniture surface coating industry. A further 
discussion of why this factor was chosen can be found in Appendix 1 to 
the Metal Furniture Risk Assessment Report in the Metal Furniture 
Docket.
    In our acute inhalation screening risk assessment, acute impacts 
are deemed negligible for HAP where acute HQs are less than or equal to 
one (even under the conservative assumptions of the screening 
assessment), and no further analysis is performed for these HAP. In 
cases where an acute HQ from the screening step is greater than 1, we 
consider additional site-specific data to develop a more refined 
estimate of the potential for acute impacts of concern. For all three 
source categories, the acute data refinements employed consisted of 
plotting the HEM-3 polar grid results for each HAP with an acute HQ 
value greater than one on aerial photographs of the facilities. We then 
assessed whether the highest acute HQs were off-site and at locations 
that may be accessible to the public (e.g., roadways and public 
buildings). These refinements are discussed more fully in the Large 
Appliances Risk Assessment Report, the Fabrics and Other Textiles Risk 
Assessment Report, and the Metal Furniture Risk Assessment Report, 
available respectively in the Large Appliances Docket, Fabrics and 
Other Textiles Docket, and Metal Furniture Docket.
4. How did we conduct the multipathway exposure and risk screening 
assessment?
    The EPA conducted a tiered screening assessment examining the 
potential for significant human health risks due to exposures via 
routes other than inhalation (i.e., ingestion). We first determined 
whether any sources in the source categories emitted any HAP known to 
be persistent and bioaccumulative in the environment (PB-HAP), as 
identified in the EPA's Air Toxics Risk Assessment Library (See Volume 
1, Appendix D, at https://www2.epa.gov/fera/risk-assessment-and-modeling-air-toxics-risk-assessment-reference-library).
    For the Surface Coating of Large Appliances; the Printing, Coating, 
and Dyeing of Fabrics and Other Textiles; and Surface Coating of Metal 
Furniture source categories, we did not identify emissions of any PB-
HAP. Because we did not identify PB-HAP emissions, no further 
evaluation of multipathway risk was conducted for these source 
categories.
5. How did we conduct the environmental risk screening assessment?
a. Adverse Environmental Effects, Environmental HAP, and Ecological 
Benchmarks
    The EPA conducts a screening assessment to examine the potential 
for adverse environmental effects as required under section 
112(f)(2)(A) of the CAA. Section 112(a)(7) of the CAA defines ``adverse 
environmental effect'' as ``any significant and widespread adverse 
effect, which may reasonably be anticipated, to wildlife, aquatic life, 
or other natural resources, including adverse impacts on populations of 
endangered or threatened species or significant degradation of 
environmental quality over broad areas.''
    The EPA focuses on eight HAP, which are referred to as 
``environmental HAP,'' in its screening assessment: Six PB-HAP and two 
acid gases. The PB-HAP included in the screening assessment are arsenic 
compounds, cadmium compounds, dioxins/furans, polycyclic organic 
matter, mercury (both inorganic mercury and methyl mercury), and lead 
compounds. The acid gases included in the screening assessment are HCl 
and hydrogen fluoride (HF).
    HAP that persist and bioaccumulate are of particular environmental 
concern because they accumulate in the soil, sediment, and water. The 
acid gases, HCl and HF, were included due to their well-documented 
potential to cause direct damage to terrestrial plants. In the 
environmental risk screening assessment, we evaluate the following four 
exposure media: Terrestrial soils, surface water bodies (includes 
water-column and benthic sediments), fish consumed by wildlife, and 
air. Within these four exposure media, we evaluate nine ecological 
assessment endpoints, which are defined by the ecological entity and 
its attributes. For PB-HAP (other than lead), both community-level and 
population-level endpoints are included. For acid gases, the ecological 
assessment evaluated is terrestrial plant communities.
    An ecological benchmark represents a concentration of HAP that has 
been linked to a particular environmental effect level. For each 
environmental HAP, we identified the available ecological benchmarks 
for each assessment endpoint. We identified, where possible, ecological 
benchmarks at the following effect levels: Probable effect levels, 
lowest-observed-adverse-effect level, and no-observed-adverse-effect 
level. In cases where multiple effect levels were available for a 
particular PB-HAP and assessment endpoint, we use all of the available 
effect levels to help us to determine whether ecological risks exist 
and, if so, whether the risks could be considered significant and 
widespread.
    For further information on how the environmental risk screening 
assessment was conducted, including a discussion of the risk metrics 
used, how the environmental HAP were identified, and how the ecological 
benchmarks were selected, see Appendix 9 of the Large Appliances Risk 
Assessment Report, the Fabrics and Other Textiles Risk Assessment 
Report, and the Metal Furniture Risk Assessment Report, in the Large 
Appliances Docket, Fabrics and Other Textiles Docket, and Metal 
Furniture Docket, respectively.
b. Environmental Risk Screening Methodology
    For the environmental risk screening assessment, the EPA first 
determined whether any 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 
emitted any of the environmental HAP. For the Surface Coating of Large 
Appliances source category, we identified emissions of HCl and HF. No 
environmental HAP were emitted from the other two source categories.
    Because one or more of the environmental HAP evaluated are emitted 
by at least one facility in the Surface Coating of Large Appliances

[[Page 46276]]

source category, we proceeded to the second step of the evaluation for 
that source category.
c. Acid Gas Environmental Risk Methodology
    The environmental screening assessment for acid gases evaluates the 
potential phytotoxicity and reduced productivity of plants due to 
chronic exposure to HCl and HF. The environmental risk screening 
methodology for acid gases is a single-tier screening assessment that 
compares modeled ambient air concentrations (from AERMOD) to the 
ecological benchmarks for each acid gas. To identify potential adverse 
environmental effects (as defined in section 112(a)(7) of the CAA) from 
emissions of HCl and HF, we evaluate the following metrics: The size of 
the modeled area around each facility that exceeds the ecological 
benchmark for each acid gas, in acres and km\2\; the percentage of the 
modeled area around each facility that exceeds the ecological benchmark 
for each acid gas; and the area-weighted average screening value around 
each facility (calculated by dividing the area-weighted average 
concentration over the 50-km modeling domain by the ecological 
benchmark for each acid gas). For further information on the 
environmental screening assessment approach, see Appendix 9 of the 
Large Appliances Risk Assessment Report in the Large Appliances Docket.
6. How did we conduct facility-wide assessments?
    To put the source category risks in context, we typically examine 
the risks from the entire ``facility,'' where the facility includes all 
HAP-emitting operations within a contiguous area and under common 
control. In other words, we examine the HAP emissions not only from the 
source category emission points of interest, but also emissions of HAP 
from all other emission sources at the facility for which we have data. 
For this source category, we conducted the facility-wide assessment 
using a dataset compiled from the 2014 NEI. The source category records 
of that NEI dataset were removed, evaluated, and updated as described 
in section II.C of this preamble: ``What data collection activities 
were conducted to support this action?'' Once a quality assured source 
category dataset was available, it was placed back with the remaining 
records from the NEI for that facility. The facility-wide file was then 
used to analyze risks due to the inhalation of HAP that are emitted 
``facility-wide'' for the populations residing within 50 km of each 
facility, consistent with the methods used for the source category 
analysis described above. For these facility-wide risk analyses, the 
modeled source category risks were compared to the facility-wide risks 
to determine the portion of the facility-wide risks that could be 
attributed to the source categories addressed in this proposal. We also 
specifically examined the facility that was associated with the highest 
estimate of risk and determined the percentage of that risk 
attributable to the source category of interest. The Large Appliances 
Risk Assessment Report, the Fabrics and Other Textiles Risk Assessment 
Report, and the Metal Furniture Risk Assessment Report, available 
respectively in the Large Appliances Docket, Fabrics and Other Textiles 
Docket, and Metal Furniture Docket, provide the methodology and results 
of the facility-wide analyses, including all facility-wide risks and 
the percentage of source category contribution to facility-wide risks.
7. How did we consider uncertainties in risk assessment?
    Uncertainty and the potential for bias are inherent in all risk 
assessments, including those performed for this proposal. Although 
uncertainty exists, we believe that our approach, which used 
conservative tools and assumptions, ensures that our decisions are 
health and environmentally protective. A brief discussion of the 
uncertainties in the RTR emissions datasets, dispersion modeling, 
inhalation exposure estimates, and dose-response relationships follows 
below. Also included are those uncertainties specific to our acute 
screening assessments, multipathway screening assessments, and our 
environmental risk screening assessments. A more thorough discussion of 
these uncertainties is included in the Large Appliances Risk Assessment 
Report, the Fabrics and Other Textiles Risk Assessment Report, and the 
Metal Furniture Risk Assessment Report, available respectively in the 
Large Appliances Docket, Fabrics and Other Textiles Docket, and Metal 
Furniture Docket. If a multipathway site-specific assessment was 
performed for this source category, a full discussion of the 
uncertainties associated with that assessment can be found in Appendix 
11 of that document, Site-Specific Human Health Multipathway Residual 
Risk Assessment Report.
a. Uncertainties in the RTR Emissions Datasets
    Although the development of the RTR emissions datasets involved 
quality assurance/quality control processes, the accuracy of emissions 
values will vary depending on the source of the data, the degree to 
which data are incomplete or missing, the degree to which assumptions 
made to complete the datasets are accurate, errors in emission 
estimates, and other factors. The emission estimates considered in this 
analysis generally are annual totals for certain years, and they do not 
reflect short-term fluctuations during the course of a year or 
variations from year to year. The estimates of peak hourly emission 
rates for the acute effects screening assessment were based on an 
emission adjustment factor applied to the average annual hourly 
emission rates, which are intended to account for emission fluctuations 
due to normal facility operations.
b. Uncertainties in Dispersion Modeling
    We recognize there is uncertainty in ambient concentration 
estimates associated with any model, including the EPA's recommended 
regulatory dispersion model, AERMOD. In using a model to estimate 
ambient pollutant concentrations, the user chooses certain options to 
apply. For RTR assessments, we select some model options that have the 
potential to overestimate ambient air concentrations (e.g., not 
including plume depletion or pollutant transformation). We select other 
model options that have the potential to underestimate ambient impacts 
(e.g., not including building downwash). Other options that we select 
have the potential to either under- or overestimate ambient levels 
(e.g., meteorology and receptor locations). On balance, considering the 
directional nature of the uncertainties commonly present in ambient 
concentrations estimated by dispersion models, the approach we apply in 
the RTR assessments should yield unbiased estimates of ambient HAP 
concentrations. We also note that the selection of meteorology dataset 
location could have an impact on the risk estimates. As we continue to 
update and expand our library of meteorological station data used in 
our risk assessments, we expect to reduce this variability.
c. Uncertainties in Inhalation Exposure Assessment
    Although every effort is made to identify all of the relevant 
facilities and emission points, as well as to develop accurate 
estimates of the annual emission rates for all relevant HAP, the 
uncertainties in our emission inventory likely dominate the 
uncertainties in the exposure assessment. Some uncertainties in our 
exposure

[[Page 46277]]

assessment include human mobility, using the centroid of each census 
block, assuming lifetime exposure, and assuming only outdoor exposures. 
For most of these factors, there is neither an under nor overestimate 
when looking at the maximum individual risks or the incidence, but the 
shape of the distribution of risks may be affected. With respect to 
outdoor exposures, actual exposures may not be as high if people spend 
time indoors, especially for very reactive pollutants or larger 
particles. For all factors, we reduce uncertainty when possible. For 
example, with respect to census-block centroids, we analyze large 
blocks using aerial imagery and adjust locations of the block centroids 
to better represent the population in the blocks. We also add 
additional receptor locations where the population of a block is not 
well represented by a single location.
d. Uncertainties in Dose-Response Relationships
    There are uncertainties inherent in the development of the dose-
response values used in our risk assessments for cancer effects from 
chronic exposures and noncancer effects from both chronic and acute 
exposures. Some uncertainties are generally expressed quantitatively, 
and others are generally expressed in qualitative terms. We note, as a 
preface to this discussion, a point on dose-response uncertainty that 
is stated in the EPA's 2005 Cancer Guidelines \16\; namely, that ``the 
primary goal of EPA actions is protection of human health; accordingly, 
as an Agency policy, risk assessment procedures, including default 
options that are used in the absence of scientific data to the 
contrary, should be health protective'' (EPA's 2005 Cancer Guidelines, 
pages 1-7). This is the approach followed here as summarized in the 
next paragraphs.

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

    Cancer UREs used in our risk assessments are those that have been 
developed to generally provide an upper bound estimate of risk. That 
is, they represent a ``plausible upper limit to the true value of a 
quantity'' (although this is usually not a true statistical confidence 
limit).\17\ In some circumstances, the true risk could be as low as 
zero; however, in other circumstances the risk could be greater.\18\ 
Chronic noncancer RfC and reference dose (RfD) values represent chronic 
exposure levels that are intended to be health-protective levels. To 
derive dose-response values that are intended to be ``without 
appreciable risk,'' the methodology relies upon an uncertainty factor 
(UF) approach \19\ which considers uncertainty, variability, and gaps 
in the available data. The UFs are applied to derive dose-response 
values that are intended to protect against appreciable risk of 
deleterious effects.

considered to cover a range of values, each end of which is 
considered to be equally plausible, and which is based on maximum 
likelihood estimates.

and Application of Inhalation Dosimetry. (https://www.epa.gov/risk/methods-derivation-inhalation-reference-concentrations-and-application-inhalation-dosimetry).
---------------------------------------------------------------------------

    Many of the UFs used to account for variability and uncertainty in 
the development of acute dose-response values are quite similar to 
those developed for chronic durations. Additional adjustments are often 
applied to account for uncertainty in extrapolation from observations 
at one exposure duration (e.g., 4 hours) to derive an acute dose-
response value at another exposure duration (e.g., one hour). Not all 
acute dose-response values are developed for the same purpose, and care 
must be taken when interpreting the results of an acute assessment of 
human health effects relative to the dose-response value or values 
being exceeded. Where relevant to the estimated exposures, the lack of 
acute dose-response values at different levels of severity should be 
factored into the risk characterization as potential uncertainties.
    Uncertainty also exists in the selection of ecological benchmarks 
for the environmental risk screening assessment. We established a 
hierarchy of preferred benchmark sources to allow selection of 
benchmarks for each environmental HAP at each ecological assessment 
endpoint. We searched for benchmarks for three effect levels (i.e., no-
effects level, threshold-effect level, and probable-effect level) but 
not all combinations of ecological assessment/environmental HAP had 
benchmarks for all three effect levels. Where multiple effect levels 
were available for a particular HAP and assessment endpoint, we used 
all of the available effect levels to help us determine whether risk 
exists and whether the risk could be considered significant and 
widespread.
    Although every effort is made to identify appropriate human health 
effect dose-response values for all pollutants emitted by the sources 
in this risk assessment, some HAP emitted by this source category are 
lacking dose-response assessments. Accordingly, these pollutants cannot 
be included in the quantitative risk assessment, which could result in 
quantitative estimates understating HAP risk. To help to alleviate this 
potential underestimate, where we conclude similarity with a HAP for 
which a dose-response value is available, we use that value as a 
surrogate for the assessment of the HAP for which no value is 
available. To the extent use of surrogates indicates appreciable risk, 
we may identify a need to increase priority for an IRIS assessment for 
that substance. We additionally note that, generally speaking, HAP of 
greatest concern due to environmental exposures and hazard are those 
for which dose-response assessments have been performed, reducing the 
likelihood of understating risk. Further, HAP not included in the 
quantitative assessment are assessed qualitatively and considered in 
the risk characterization that informs the risk management decisions, 
including consideration of HAP reductions achieved by various control 
options.
    For a group of compounds that are unspeciated (e.g., glycol 
ethers), we conservatively use the most protective dose-response value 
of an individual compound in that group to estimate risk. Similarly, 
for an individual compound in a group (e.g., ethylene glycol diethyl 
ether) that does not have a specified dose-response value, we also 
apply the most protective dose-response value from the other compounds 
in the group to estimate risk.
e. Uncertainties in Acute Inhalation Screening Assessments
    In addition to the uncertainties highlighted above, there are 
several factors specific to the acute exposure assessment that the EPA 
conducts as part of the risk review under section 112 of the CAA. The 
accuracy of an acute inhalation exposure assessment depends on the 
simultaneous occurrence of independent factors that may vary greatly, 
such as hourly emissions rates, meteorology, and the presence of humans 
at the location of the maximum concentration. In the acute screening 
assessment that we conduct under the RTR program, we assume that peak 
emissions from the source category and worst-case

[[Page 46278]]

meteorological conditions co-occur, thus resulting in maximum ambient 
concentrations. These two events are unlikely to occur at the same 
time, making these assumptions conservative. We then include the 
additional assumption that a person is located at this point during 
this same time period. For these source categories, these assumptions 
would tend to be worst-case actual exposures as it is unlikely that a 
person would be located at the point of maximum exposure during the 
time when peak emissions and worst-case meteorological conditions occur 
simultaneously.
f. Uncertainties in the Multipathway and Environmental Risk Screening 
Assessments
    For each source category, we generally rely on site-specific levels 
of PB-HAP or environmental HAP emissions to determine whether a refined 
assessment of the impacts from multipathway exposures is necessary or 
whether it is necessary to perform an environmental screening 
assessment. None of the three source categories in this action emit PB-
HAP, therefore, multipathway assessments were not conducted. Since no 
environmental HAP are emitted from the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles source category or the Surface Coating of 
Metal Furniture source category, an environmental risk screen was not 
conducted for these categories. Small amounts of the environmental HAP, 
HCl, and HF are emitted from the Surface Coating of Large Appliances 
source category, therefore, an environmental risk screen was conducted.
    The environmental screening assessment relies on the outputs from 
AERMOD--that estimates environmental pollutant concentrations for two 
acid gases (HCl and HF). Two important types of uncertainty associated 
with the use of these models in RTR risk assessments and inherent to 
any assessment that relies on environmental modeling are model 
uncertainty and input uncertainty.\20\ Model uncertainty concerns 
whether the model adequately represents the actual processes (e.g., 
movement and accumulation) that might occur in the environment. For 
example, does the model adequately describe the movement of a pollutant 
through the soil? This type of uncertainty is difficult to quantify. 
However, based on feedback received from previous EPA SAB reviews and 
other reviews, we are confident that the models used in the screening 
assessments are appropriate and state-of-the-art for the environmental 
screening risk assessment conducted in support of RTR.
---------------------------------------------------------------------------

    \20\ In the context of this discussion, the term ``uncertainty'' 
as it pertains to exposure and risk encompasses both variability in 
the range of expected inputs and screening results due to existing 
spatial, temporal, and other factors, as well as uncertainty in 
being able to accurately estimate the true result.
---------------------------------------------------------------------------

    Input uncertainty is concerned with how accurately the models have 
been configured and parameterized for the assessment at hand. For the 
environmental screening assessment for acid gases, we employ a single-
tiered approach. We use the modeled air concentrations and compare 
those with ecological benchmarks.

IV. Analytical Results and Proposed Decisions

A. What are the analytical results and proposed decisions for the 
Surface Coating of Large Appliances source category?
1. What are the results of the risk assessment and analyses?
    As described in section III of this preamble, for the Surface 
Coating of Large Appliances source category, we conducted a risk 
assessment for all HAP emitted. We present results of the risk 
assessment briefly below and in more detail in the Large Appliances 
Risk Assessment Report in the Large Appliances Docket (Docket ID No. 
EPA-HQ-OAR-2017-0670).
a. Inhalation Risk Assessment Results
    Table 2 of this preamble provides a summary of the results of the 
inhalation risk assessment for the source category. As discussed in 
section III.C.2 of this preamble, we set MACT-allowable HAP emission 
levels at large appliance coating facilities equal to 1.2 times actual 
emissions. For more detail about the MACT-allowable emission levels, 
see Appendix 1 to the Large Appliances Risk Assessment Report in the 
Large Appliances Docket.

\1\ The target organ specific hazard index (TOSHI) is the sum of the chronic noncancer hazard quotients 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.

    The results of the 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. The total 
estimated annual cancer incidence (national) from these facilities 
based on actual emission levels is 0.0001 excess cancer cases per year, 
or one case in every 10,000 years.
b. Acute Risk Results
    Table 2 of this preamble shows the acute risk results for the 
Surface Coating of Large Appliances source category. The screening 
analysis for acute impacts was based on an industry specific multiplier 
of 1.2, to estimate the peak emission rates from the average rates. For 
more detailed acute risk results,

[[Page 46279]]

refer to the Large Appliances Risk Assessment Report in the Large 
Appliances Docket.
c. Multipathway Risk Screening Results
    There are no PB-HAP emitted by facilities in the Surface Coating of 
Large Appliances source category. Therefore, we do not expect any human 
health multipathway risks as a result of emissions from this source 
category.
d. Environmental Risk Screening Results
    The emissions data for the Surface Coating of Large Appliances 
source category indicate that two environmental HAP are emitted by 
sources within this source category: HCl and HF. Therefore, we 
conducted a screening-level evaluation of the potential adverse 
environmental risks associated with emissions of HCl and HF for the 
Surface Coating of Large Appliances source category. For both HCl and 
HF, each individual concentration (i.e., each off-site data point in 
the modeling domain) was below the ecological benchmarks for all 
facilities. Therefore, we do not expect an adverse environmental effect 
as a result of HAP emissions from this source category.
e. Facility-Wide Risk Results
    One facility has a facility-wide cancer MIR greater than or equal 
to 1-in-1 million. The maximum facility-wide cancer MIR is 6-in-1 
million, driven by chromium (VI) compounds from a cleaning/pretreatment 
operation. The total estimated cancer incidence from the whole facility 
is 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 of the ten facilities in this source category. The 
maximum facility-wide TOSHI for the source category is estimated to be 
0.2, driven by emissions of methylene diphenyl diisocyanate from foam 
produced as part of plastic products manufacturing.
f. What demographic groups might benefit from this regulation?
    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 km and within 50 
km of the facilities. In the analysis, we evaluated the distribution of 
HAP-related cancer and noncancer risks from the Surface Coating of 
Large Appliances source category across different demographic groups 
within the populations living near facilities.\21\
---------------------------------------------------------------------------

    \21\ Demographic groups included in the analysis are: White, 
African American, Native American, other races and multiracial, 
Hispanic or Latino, children 17 years of age and under, adults 18 to 
64 years of age, adults 65 years of age and over, adults without a 
high school diploma, people living below the poverty level, people 
living above the poverty level, and linguistically isolated people.
---------------------------------------------------------------------------

    Results of the demographic analysis indicate that, for two of the 
11 demographic groups, ``African American'' and ``Below the Poverty 
Level,'' the percentage of the population living within 5 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 greater than one 
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, September 2017 
(hereafter referred to as the Large Appliances Demographic Analysis 
Report) in the Large Appliances Docket.
2. What are our proposed decisions regarding risk acceptability, ample 
margin of safety, and adverse environmental effects?
a. Risk Acceptability
    As noted in section III.A of this preamble, we weigh all health 
risk factors in our risk acceptability determination, including the 
cancer MIR, the number of persons in various cancer and noncancer risk 
ranges, cancer incidence, the maximum noncancer TOSHI, the maximum 
acute noncancer HQ, the extent of noncancer risks, the distribution of 
cancer and noncancer risks in the exposed population, and risk 
estimation uncertainties (54 FR 38044, September 14, 1989).
    For the Surface Coating of Large Appliances source category, the 
risk analysis indicates that the cancer risks to the individual most 
exposed could be up to 0.9-in-1 million due to actual emissions and up 
to 1-in-1 million based on allowable emissions. These risks are 
considerably less than 100-in-1 million, which is the presumptive upper 
limit of acceptable risk. The risk analysis also shows very low cancer 
incidence (0.0001 cases per year for actual emissions and 0.0002 cases 
per year for allowable emissions), and we did not identify potential 
for adverse chronic noncancer health effects. The acute noncancer risks 
based on actual emissions are low at an HQ of 2 for glycol ethers at 
one facility. Therefore, we find there is little potential concern of 
acute noncancer health impacts from actual emissions. In addition, the 
risk assessment indicates no significant potential for multipathway 
health effects.
    Considering all of the health risk information and factors 
discussed above, including the uncertainties discussed in section 
III.C.7 of this preamble, we propose to find that the risks from the 
Surface Coating of Large Appliances source category are acceptable.
b. Ample Margin of Safety Analysis
    Although we are proposing that the risks from the Surface Coating 
of Large Appliances source category are acceptable, risk estimates for 
approximately 50 individuals in the exposed population are above 1-in-1 
million at the allowable emissions level. Consequently, we further 
considered whether the MACT standards for the Surface Coating of Large 
Appliances source category provide an ample margin of safety to protect 
public health. In this ample margin of safety analysis, we investigated 
available emissions control options that might reduce the risk from the 
source category. We considered this information along with all of the 
health risks and other health information considered in our 
determination of risk acceptability.
    As described in section III.B of this preamble, our technology 
review focused on identifying developments in practices, processes, and 
control technologies for the Surface Coating of Large Appliances source 
category, and the EPA reviewed various information sources regarding 
emission sources that are currently regulated by the Surface Coating of 
Large Appliances NESHAP.
    The only development identified in the technology review is the use 
of high-efficiency spray equipment. We estimated no costs or emissions 
reductions that would be achieved by switching to high efficiency 
application methods for this source category because we expect that 
large appliance surface coating facilities are already using high 
efficiency coating application methods due to state VOC rules and the 
economic incentives of using more efficient application methods. 
Because quantifiable

[[Page 46280]]

reductions in risk are unlikely, we are proposing that the current 
standards provide an ample margin of safety. As discussed below, 
however, we are proposing to require this technology under the 
technology review. We request comment on this proposed requirement and 
whether any facilities in this source category do not currently use 
high efficiency coating application methods.
c. Environmental Effects
    The emissions data for the Surface Coating of Large Appliances 
source category indicate that two environmental HAP are emitted by 
sources within this source category: HCl and HF. The screening-level 
evaluation of the potential for adverse environmental risks associated 
with emissions of HCl and HF from the Surface Coating of Large 
Appliances source category indicated that each individual concentration 
(i.e., each off-site data point in the modeling domain) was below the 
ecological benchmarks for all facilities. In addition, we are unaware 
of any adverse environmental effects caused by HAP emitted by this 
source category. Therefore, we do not expect there to be an adverse 
environmental effect as a result of HAP emissions from this source 
category and we are proposing that it is not necessary to set a more 
stringent standard to prevent, taking into consideration costs, energy, 
safety, and other relevant factors, an adverse environmental effect.
3. What are the results and proposed decisions based on our technology 
review?
    Our technology review focused on identifying developments in 
practices, processes, and control technologies for the Surface Coating 
of Large Appliances source category, and the EPA reviewed various 
information sources regarding emission sources that are currently 
regulated by the Surface Coating of Large Appliances NESHAP. These 
emission sources include coating mixing; coating application; coating 
curing; conveying coatings, thinners and cleaning materials; and waste 
storage and handling. Based on our review, we identified, as outlined 
below, one development in technology, the application of high-
efficiency spray equipment, for the Surface Coating of Large Appliances 
source category. A brief summary of the EPA's findings in conducting 
the technology review of large appliance surface coating operations 
follows. For a detailed discussion of the EPA's findings, refer to the 
Large Appliances Technology Review Memorandum in the Large Appliances 
Docket.
    The technology basis for the original MACT standards for existing 
and new or reconstructed sources under the Surface Coating of Large 
Appliance NESHAP was the use of lower-HAP coatings, thinners, and 
cleaning materials. Add-on capture and control systems for organic HAP 
were rarely used by the industry at that time (65 FR 81142, December 
22, 2000). During development of that rulemaking, we identified and 
considered three alternatives more stringent than the MACT floor level 
of control for organic HAP: (1) Conversion to powder coatings; (2) 
conversion to liquid coatings that have a very low, or no, organic HAP 
content; and (3) use of add-on capture systems and control devices 
(i.e., an emission capture system such as a spray booth) used in 
conjunction with thermal recuperative oxidizers, regenerative thermal 
oxidizers (RTO), catalytic oxidizers, or activated carbon adsorbers). 
However, we did not adopt any of these alternatives because they were 
not applicable beyond a small subset of facilities or would not be 
cost-effective for the incremental emission reductions achieved beyond 
the MACT floor level of control (65 FR 81143).
    Using the EPA's NEI and the ECHO databases, we identified ten large 
appliance surface coating facilities that are currently subject to the 
Surface Coating of Large Appliances NESHAP. We reviewed their state 
operating permits to determine whether any are using add-on control 
technologies to comply with the NESHAP. Two of the ten facilities have 
add-on controls, but the permits indicate that nine of the ten 
facilities are using the compliant materials option or the emission 
rate without add-on controls option to demonstrate compliance with the 
NESHAP. One facility with an add-on control is using the add-on control 
to comply with only a VOC emission limitation but not to comply with 
the NESHAP. The second facility with add-on controls does not have add-
on controls on all coating operations, but a 2017 inspection report 
indicates that the facility is using the emission rate with add-on 
controls compliance option. This one facility differs from the others 
complying with subpart NNNN in that it is a contract coating operation 
that performs surface coating on parts of large appliances, but also 
performs surface coating on parts for a variety of industries. All of 
the other facilities are large appliance manufacturers. Therefore, the 
result from this one facility is not applicable to other facilities 
dedicated to manufacturing just large appliances. Our search of the 
RBLC database did not identify any additional large appliance 
manufacturers using an add-on control device or subject to an emission 
limit more stringent than in subpart NNNN.
    The use of a RTO and permanent total enclosure (PTE) was considered 
during development of the Large Appliances NESHAP as a control 
technology capable of achieving an efficiency of 95 percent, but was 
rejected as not cost effective for the incremental emission reductions 
that would be achieved relative to the MACT floor level of control. We 
found no information that any improvements in PTE and add-on control 
technology have occurred that would affect the cost-effectiveness of a 
PTE and add-on control or result in additional emission reductions. 
Therefore, EPA finds there have not been improvements in the RTO/PTE 
since we promulgated the NESHAP to support requiring this technology 
for the large appliance source category as part of the technology 
review.
    We have not identified any process change or pollution prevention 
alternative that could be broadly applied to the large appliance 
coating industry. We reviewed the ACA Industry Market Analysis for 
recent trends in coating technology in the large appliance industry. 
The ACA Industry Market Analysis reports that the large appliance 
manufacturing industry has largely shifted from liquid coatings to 
powder coatings and pre-coated metal coil substrate. Specifically, the 
ACA Industry Market Analysis states that the volume of liquid finishes 
used in appliance finishes decreased by 67 percent between 2007 and 
2014 as a result of the shift to powder coatings and pre-coated metal 
prepared by coil coating facilities. However, a substantial fraction of 
the coatings used (23 percent of coatings applied by large appliance 
coating facilities) are still liquid coatings, and the EPA is currently 
unable to determine whether all surface coating operations can be 
shifted to powder coatings or pre-coated metal coil substrate. The 
shift to the use of more powder coatings on specific parts has occurred 
as an expected industry response to comply with the original Surface 
Coating of Large Appliances NESHAP, but the shift was not category-
wide, nor was it appropriate for all parts or segments of the industry. 
Since it is not a technology that can be adopted more broadly, we are 
not proposing to require use of powder coatings under the technology 
review. One area of development identified in the ACA Industry Market 
Analysis is the use of low-energy curing powders, such as

[[Page 46281]]

ultraviolet (UV)-cured powders, that can be used on plastic substrates. 
UV-cured powders are powder coatings that use ultraviolet light as the 
radiant energy source to initiate a photochemical reaction to generate 
a crosslinked network of polymer on the substrate surface. However, we 
were unable to find any information from our review of permits that UV-
cured powder coating has been applied at large appliance surface 
coating facilities. For these reasons, EPA finds that there have not 
been developments in powder coatings and/or pre-coated metal coil 
substrates since we promulgated the NESHAP to support requiring this 
technology for all the sources in the large appliance source category 
as part of the technology review.
    The technology review conducted for the Wood Furniture 
Manufacturing Operations NESHAP (40 CFR part 63, subpart JJ) identified 
air-assisted airless spraying, a more efficient coating application 
technology, as a development in process equipment, and adopted 
regulations preventing the use of conventional air-atomized coating 
spray guns. Several other surface coating NESHAP specify that high 
efficiency spray guns must be used for spray applied coatings (i.e., 40 
CFR part 63, subparts GG and JJ) or the compliance demonstration takes 
into account the transfer efficiency of the spray equipment, and the 
standards are based on high-efficiency spray application (e.g., 40 CFR 
part 63, subpart IIII). Using high-efficiency spray equipment reduces 
the amount of coating applied compared to conventional spray equipment 
and, therefore, reduces emissions.
    The Surface Coating of Large Appliances NESHAP does not contain any 
standards specifying the type of spray equipment that must be used when 
coatings are spray-applied. However, many facilities complying with the 
Surface Coating of Large Appliances NESHAP also are required by state 
VOC regulations in Indiana, Ohio, and Wisconsin to use high-efficiency 
spray guns for coatings that are spray applied. We expect that large 
appliance surface coating facilities in other states are also using 
high-efficiency application equipment for spray applied coatings as a 
cost saving measure 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 expect that the high-
efficiency application equipment would provide cost savings from an 
engineering perspective, we are uncertain of other factors that 
facilities may need to consider if choosing to switch to high-
efficiency application equipment. Due to the competitive marketplace 
and the number of units going through these surface coating facilities, 
there may be facility specific operational, coating adherence, coating 
drying time, material compatibility, or other reasons that a facility 
may not have chosen to switch to high-efficiency spray equipment. We 
request comment on these and other aspects of facility decision making, 
as the agency has limited information on the market penetration of this 
technology and these other factors.
    Based on these findings, we are proposing to revise the Surface 
Coating of Large Appliances 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, must be demonstrated to achieve 
transfer efficiency equivalent to or better than 65 percent. There are 
four types of high efficiency spray equipment technologies that have 
been applied in these applications that could achieve the 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 may also be used with 
documentation demonstrating at least 65 percent transfer efficiency. 
Spray application equipment sources not using the emission rate with 
add-on control compliance option, and/or using alternative spray 
application equipment technologies other than the four listed, must 
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 
may be certified by manufacturers of the spray equipment, on behalf of 
spray-applied coating operations sources, 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.'' When using these equivalency procedures and/or 
guidelines, facilities would not be required to submit an application 
with the test plan or protocol to the Administrator, conduct the test 
in the presence of an Administrator's representative, or submit test 
results to the Administrator for review or approval. Instead, they 
would be required to maintain records demonstrating the transfer 
efficiency achieved, including a description of the procedures and/or 
guidelines used. We are proposing that all spray equipment used for 
spray-applied coating operations would be required to be operated 
according to company procedures, local specified operating procedures, 
or the manufacturer's specifications, whichever is determined to meet 
the 65 percent transfer efficiency. Further, we are proposing 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.''
    Considering just the incremental cost of the high efficiency spray 
equipment and savings due to using less material consumption, we expect 
that all facilities have already switched to high efficiency 
application methods. However, if a large appliance surface coating 
facility not using the emission rate with add-on control compliance 
option replaced their existing coating spray guns with a high-
efficiency spray gun required by this proposed rule, such as an air-
assisted airless spray gun, an estimated cost to do so would be 
approximately $700 per device, based on vendor information. See the 
memorandum titled Impacts of Prohibiting the Use of Conventional Spray 
Guns in the Wood Manufacturing Operations Source Category (Docket ID 
Number EPA-HQ-OAR-2010-0786 EPA). Any potential costs would be offset 
by savings in the cost of coatings, filters, and solid waste disposal 
fees for handling the liners used to capture coating overspray. EPA 
requests comment on this cost estimation, and whether other costs are 
associated with switching to high-efficiency spray equipment that the 
agency should consider in this technology review, such as operational 
efficiency changes, ancillary equipment changes, repair and maintenance 
costs, employee training or other factors
    We have not estimated the emissions reductions achieved by 
switching to high efficiency application methods for this source 
category because we expect

[[Page 46282]]

that all large appliance surface coating facilities are using high 
efficiency coating application methods. However, if any facilities 
switch to high efficiency application equipment, there would likely be 
emission reductions. As an example, using the Wood Furniture 
Manufacturing Operations cost methodology, if a facility switched from 
conventional spray guns with 45 percent transfer efficiency to air-
assisted airless spray guns with 65 percent transfer efficiency, to get 
one unit of solids on the part, an air-assisted airless spray gun needs 
1.54 gallons of coating, compared to 2.22 gallons for a conventional 
spray gun. This increase transfer efficiency represents a 31 percent 
decrease in coating consumption, leading to a corresponding decrease in 
organic HAP emissions from coating application. For more information on 
the Wood Furniture Manufacturing Operations cost methodology, including 
the cost of spray gun equipment and calculation of potential HAP 
emission reductions, see the memorandum titled Impacts of Prohibiting 
the Use of Conventional Spray Guns in the Wood Manufacturing Operations 
Source Category (EPA Docket ID Number EPA-HQ-OAR-2010-0786 EPA). We 
request comment on whether facilities in the Large Appliances source 
category are not using high efficiency spray equipment and why it is 
not being used. Refer to section IV.A.5 of this preamble for a 
discussion of the compliance schedule for using high efficiency spray 
equipment
    Finally, we identified no developments in work practices or 
procedures for the Surface Coating of Large Appliances source category, 
including work practices and procedures that are currently prescribed 
in the NESHAP. The current Surface Coating of Large Appliances NESHAP 
standards require that, if a facility uses add-on controls to comply 
with the emission limitations, the facility must develop and implement 
a work practice plan to minimize organic HAP emissions from the 
storage, mixing, and conveying of coatings, thinners, and cleaning 
materials used in, and waste materials generated by, all coating 
operations for which emission limits are established. The current work 
practice requirements address the potential emission sources that are 
normally located outside of the emission sources that are routed to the 
control device, and no new measures have been identified to further 
reduce the emissions from these sources. For further discussion of the 
technology review results, refer to the Large Appliances Technology 
Review Memorandum in the Large Appliances Docket.
    In section III.B. above, we describe our typical approach for 
conducting technology reviews and the types of information we gather 
and evaluate as part of these reviews. In addition, we solicit comment 
on the relationship between the CAA section 112(d)(6) technology review 
and the CAA section 112(f) risk review. As we described in the preamble 
of the Coke Ovens RTR Final rule published on April 15, 2005 (70 FR 
20009), we believe that the results of a CAA section 112(f) risk 
determination for a CAA section 112(d) standard should be key factors 
in any subsequent CAA section 112(d)(6) determination for that 
standard. In the Coke Ovens RTR final rule, the agency described 
potential scenarios where it may not be necessary to revise the 
standards based on developments in technologies, practices or processes 
if the remaining risks associated with air emissions from a source 
category have already been reduced to a level where we have determined 
further reductions under CAA section 112(f) are not necessary. Under 
one scenario, if the ample margin of safety analysis for the CAA 
section 112(f) determination was not based on the availability or cost 
of particular control technologies, then advances in air pollution 
control technology would not necessarily be a cause to revise the MACT 
standard pursuant to CAA section 112(d)(6), because the CAA section 
112(f) standard (or a CAA section 112(d) standard evaluated pursuant to 
CAA section 112(f)) would continue to assure an adequate level of 
safety. Under another scenario, if the ample margin of safety analysis 
for a CAA section 112(f) standard (or a CAA section 112(d) standard 
evaluated pursuant to CAA section 112(f)) shows that lifetime excess 
cancer risks to the individual most exposed to emissions from a source 
in the category is less than 1-in-1 million, and the remaining risk 
associated with threshold pollutants falls below a similar threshold of 
safety, then no further revision under CAA section 112(d)(6) would be 
necessary, because an ample margin of safety has already been assured.
    We solicit comment on whether revisions to the NESHAP are 
``necessary'', as that term is used in CAA section 112(d)(6), in 
situations where 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 solicit comment on our conclusion that, if 
remaining risks associated with air emissions from a source category 
have already been reduced to levels where we have determined under CAA 
section 112(f) that further reductions are not necessary, then it is 
not ``necessary'' to revise the standards based on developments in 
technologies, practices or processes under CAA section 112(d)(6). See 
CAA s. 112(d)(6) (``The Administrator shall review, and revise as 
necessary . . .''). We also solicit 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 
or lower, cancer risk levels would be appropriate to consider if they 
assured an ample margin of safety.
    Though we believe the results of the ample margin of safety 
analysis may eliminate the need to revise the emissions standards as 
based on developments in technologies practices and processes, we 
conducted a technology review to determine if any developments to 
further reduce HAP emissions have occurred, and to consider whether the 
current standards should be revised to reflect any such developments. 
We believe that the use of high-efficiency spray equipment in the 
Surface Coating of Large Appliances source category is cost effective, 
presents minimal or no additional burden and achieves reductions in 
actual or potential HAP emissions. Therefore, based on our technology 
review, we are proposing to require the use of high-efficiency spray 
application equipment for the Surface Coating of Large Appliances 
source category. Note that the discussion directly above also applies 
to the Printing, Coating, and Dyeing of Fabrics and Other Textiles and 
Surface Coating of Metal Furniture source categories.
4. What other actions are we proposing?
    In the Surface Coating of Large Appliances source category, we are 
proposing to require electronic submittal of notifications, semi-annual 
reports and compliance reports (which include performance test 
reports). In addition, we are proposing revisions to the startup, 
shutdown, and malfunction (SSM) provisions of the MACT rule 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

[[Page 46283]]

from the requirement to comply with otherwise applicable CAA section 
112(d) emission standards during periods of SSM. We also propose other 
changes, including addition of EPA Method 18, updating references to 
equivalent test methods, making technical and editorial revisions, and 
incorporation by reference (IBR) of alternative test methods. Our 
analyses and proposed changes related to these issues are discussed in 
the sections below.
    Though we are not proposing to change reporting frequency currently 
in the rule, we are requesting comment on changing the reporting 
frequency for all reports to EPA from semi-annual to annual due to the 
potential redundancy of these reporting requirements. We recognize that 
Title V permits have a statutory requirement for semi-annual reports, 
which are generally reported to state regulatory agencies. However, we 
are not certain that changing the report frequency for just the reports 
submitted to EPA in this NESHAP will result in a reporting and 
recordkeeping burden reduction. We request comment and supporting 
information on the burden impact of changing the reporting requirement 
to annual for the reporting to EPA.
a. Electronic Reporting Requirements
    The EPA proposes to require owners and operators of Surface Coating 
of Large Appliances facilities to submit electronic copies of initial 
notifications required in 40 CFR 63.9(b), notifications of compliance 
status required in 40 CFR 63.9(h), performance test reports, and 
semiannual reports through the EPA's Central Data Exchange (CDX), using 
the Compliance and Emissions Data Reporting Interface (CEDRI).\22\ For 
further information regarding the electronic data submission process, 
please refer to the memorandum titled Electronic Reporting for Surface 
Coating of Large Appliances, Subpart NNNN, May 2018, in the Large 
Appliances Docket. Note that the rule proposes to require that 
performance test results collected using test methods that are not 
supported by the ERT as listed on the EPA's ERT website at the time of 
the test be submitted in portable document format (PDF) using the 
attachment module of the ERT.
---------------------------------------------------------------------------

    \22\ https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri.
---------------------------------------------------------------------------

    The EPA proposes that electronic submittal of notifications and 
reports (initial notifications required in 40 CFR 63.9(b), 
notifications of compliance status required in 40 CFR 63.9(h), and 
semiannual reports) be required using electronic reporting forms that 
the EPA will make available in CEDRI. No specific form is proposed at 
this time for the initial notifications required in 40 CFR 63.9(b) and 
notifications of compliance status required in 40 CFR 63.9(h). Until 
the EPA has completed electronic forms for these notifications, the 
notifications will be required to be submitted via CEDRI in PDF. For 
semiannual reports, the EPA proposes that owners or operators use the 
appropriate spreadsheet template in CEDRI for 40 CFR part 63, subpart 
NNNN, or an alternate electronic file format consistent with the form's 
extensible markup language schema. For further information regarding 
the electronic data submission process, please refer to the spreadsheet 
attached to the memorandum titled Electronic Reporting Template for 
Surface Coating of Large Appliances, Subpart NNNN Semiannual Reports, 
May 2018, in the Large Appliances Docket. We specifically request 
comment on the format and usability of the template (e.g., filling out 
and uploading a provided spreadsheet versus entering the required 
information into an on-line fillable CEDRI web form), as well as the 
content, layout, and overall design of the template. Prior to 
availability of the final semiannual compliance report template in 
CEDRI, owners or operators of affected sources will be required to 
submit semiannual compliance reports as otherwise required by the 
Administrator. After development of the final template, sources will be 
notified about its availability via the CEDRI website and the 
Clearinghouse for Inventories and Emissions Factors (CHIEF) 
Listserv.\23\ We plan to finalize a required reporting format with the 
final rule. The owner or operator would begin submitting reports 
electronically with the next report that is due, once the electronic 
template has been available for at least one year.
---------------------------------------------------------------------------

    \23\ https://www.epa.gov/air-emissions-inventories/air-emissions-inventory-listservs.
---------------------------------------------------------------------------

    As noted above, we propose that 40 CFR part 63, subpart NNNN, 
performance test reports be submitted through the EPA's Electronic 
Reporting Tool (ERT). The proposal to submit performance test data 
electronically to the EPA applies only if the EPA has developed an 
electronic reporting form for the test method as listed on the EPA's 
ERT website (https://www3.epa.gov/ttn/chief/ert/ert_info.pdf) and the 
agency has obtained an approved OMB control number consistent with the 
requirements of the Paperwork Reduction Act. Note that all but one of 
the EPA test methods (optional EPA Method 18) listed under the 
emissions destruction or removal efficiency section of 40 CFR part 63, 
subpart NNNN, are currently supported by the ERT. As mentioned above, 
the rule proposes that should an owner or operator choose to use Method 
18, then its results would be submitted in PDF using the attachment 
module of the ERT.
    We propose to provide owners or operators of facilities with 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 CEDRI or for a force majeure event in the time 
just prior to a report's due date.
    In 40 CFR 63.4121(d), we propose to address the situation where an 
extension may be warranted due to outages of the EPA's CDX or CEDRI 
that may prevent access to the system and submittal of the required 
reports. If either the CDX or CEDRI is unavailable at any time 
beginning five business days prior to the date that the submission is 
due, and the unavailability prevents the submission of a report by the 
required date, we propose to enable the owner or operator of a facility 
to assert a claim of EPA system outage. We consider five business days 
prior to the reporting deadline to be an appropriate timeframe because 
if the system is down and returns to service prior to this time, 
facilities will still have 1 week prior to the reporting deadline to 
complete reporting once the system is back online. However, if the CDX 
or CEDRI is down during the week a report is due, we realize that this 
could greatly impact the ability to submit a required report on time. 
We will notify owners or operators of facilities about known outages as 
far in advance as possible by notification using the CHIEF Listserv, 
posting on the CEDRI website, and posting on the CDX website so that 
owners or operators can plan accordingly and still meet the reporting 
deadlines. However, if a planned or unplanned outage of the EPA's CDX 
or CEDRI occurs and an owner or operator of a facility believes that 
the outage will affect or it has affected compliance with an electronic 
reporting requirement, the proposed rule provides a process to assert 
such a claim.
    Also in 40 CFR 63.4121(e), we propose to address the situation 
where an extension may be warranted due to a force majeure event, which 
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

[[Page 46284]]

compliance with the requirement to submit a report electronically as 
required by this rule. Examples of such events are acts of nature, acts 
of war or terrorism, equipment failures, or safety hazards that are 
beyond the control of the facility. If such an event occurs, or is 
still occurring, or if there are still lingering effects of the event 
in the five business days prior to a submission deadline, the proposed 
rule provides a process to assert a claim of force majeure.
    While we propose these potential extensions to protect facilities 
from noncompliance with reporting requirements in cases when a facility 
cannot successfully submit a report by the reporting deadline for 
reasons outside of its control as described above, we do not propose an 
extension for other circumstances. Facility owners or operators should 
register for CEDRI far in advance of the initial compliance date to 
ensure that they can complete the identity proofing process prior to 
the initial compliance date. Additionally, we recommend developing 
reports early in case any questions arise during the reporting process.
    As discussed in the Electronic Reporting for Surface Coating of 
Large Appliances Subpart NNNN memorandum, electronic submittal of the 
reports addressed in this proposed rulemaking will increase the 
usefulness of those reports, and in keeping with current trends in data 
availability, will further assist in the protection of public health 
and the environment and will ultimately result in less burden on 
regulated facilities. Electronic submittal will also improve compliance 
by facilitating the ability of regulated facilities to demonstrate 
compliance and the ability of air agencies and the EPA to assess and 
determine compliance. Moreover, electronic reporting is consistent with 
EPA's plan \24\ to implement Executive Order 13563 and agency-wide 
policy to implement the White House's Digital Government Strategy \25\ 
by specifying that new regulations will require reports to be 
electronic to the maximum extent possible. In addition to supporting 
regulation development, control strategy development, and other air 
pollution control activities, we believe that having an electronic 
database populated with performance test data will save industry, air 
agencies, and the EPA significant time, money, and effort while 
improving the quality of emission inventories and air quality 
regulations and enhancing the public's access to this important 
information.

b. Startup, Shutdown, and Malfunction Requirements
1. Proposed Elimination of the SSM Exemption
    In its 2008 decision in Sierra Club v. EPA, 551 F.3d 1019 (D.C. 
Cir. 2008), the United States Court of Appeals for the District of 
Columbia Circuit vacated portions of two provisions in the EPA's CAA 
section 112 regulations governing the emissions of HAP during periods 
of SSM. Specifically, the Court vacated the SSM exemption contained in 
40 CFR 63.6(f)(1) and 40 CFR 63.6(h)(1), holding that under section 
302(k) of the CAA, emissions standards or limitations must be 
continuous in nature and that the SSM exemption violates the CAA's 
requirement that some CAA section 112 standards apply continuously.
    We are proposing the elimination of the SSM exemption in this rule. 
Consistent with Sierra Club v. EPA, we are proposing standards in this 
rule that apply at all times. We are also proposing several revisions 
to Table 2 to subpart NNNN of part 63 (Applicability of General 
Provisions to Subpart NNNN, hereafter referred to as the ``General 
Provisions table to subpart NNNN''), as explained in more detail below 
in section IV.A.4.b.2 of this preamble. For example, we are proposing 
to eliminate the incorporation of the General Provisions' requirement 
that the source develop an SSM plan. We are also proposing to delete 40 
CFR 63.4163(h), which specifies that deviations during SSM periods are 
not violations. Further, we are proposing to eliminate and revise 
certain recordkeeping and reporting requirements related to the SSM 
exemption as further described below. The EPA has attempted to ensure 
that the provisions we are proposing to eliminate are inappropriate, 
unnecessary, or redundant in the absence of the SSM exemption. We are 
seeking comment on the specific proposed deletions and revisions and 
also whether additional provisions should be revised to achieve the 
stated goal.
    In proposing these rule amendments, the EPA has taken into account 
startup and shutdown periods and, for the reasons explained below, has 
not proposed alternate standards for those periods. Startups and 
shutdowns are part of normal operations for the Surface Coating of 
Large Appliances source category. As currently specified in 40 CFR 
63.4092(b), any coating operation(s) for which you use the emission 
rate with add-on controls option must meet operating limits ``at all 
times,'' except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to 40 CFR 63.4161(h). Also, 
as currently specified in 40 CFR 63.4100(a)(2), any coating 
operation(s) for which you use the emission rate with add-on controls 
option must be in compliance ``at all times'' with the emission limit 
in 40 CFR 63.4090 and work practice standards in 40 CFR 63.4093. This 
means that during startup and shutdown periods, in order for a facility 
using add-on controls to meet the emission and operating standards, the 
control device for a coating operation needs to be turned on and 
operating at specified levels before the facility begins coating 
operations, and the control equipment needs to continue to be operated 
until after the facility ceases coating operations. In some cases, the 
facility needs to run thermal oxidizers on supplemental fuel before 
there are enough VOC for the combustion to be (nearly) self-sustaining. 
The proposed language in 40 CFR 63.4100 requires that the owner or 
operator operate and maintain the coating operation, including 
pollution control equipment, at all times to minimize emissions. See 
section IV.A.4.b.2 of this preamble for further discussion of this 
proposed revision.
    Periods of startup, normal operations, and shutdown are all 
predictable and routine aspects of a source's operations. Malfunctions, 
in contrast, are neither predictable nor routine. Instead they are, by 
definition sudden, infrequent and not reasonably preventable failures 
of emissions control, process or monitoring equipment. (40 CFR 63.2) 
(Definition of malfunction). The EPA interprets CAA section 112 as not 
requiring emissions that occur during periods of malfunction to be 
factored into development of CAA section 112 standards and this reading 
has been upheld as reasonable by the Court in U.S. Sugar Corp. v. EPA, 
830 F.3d 579, 606-610 (2016). Under CAA section 112, emissions 
standards for new sources must be no less stringent than the level 
``achieved'' by the best controlled similar source and for existing 
sources generally must be no less stringent than the average emission 
limitation ``achieved'' by the best performing 12 percent of sources in 
the category. There is nothing in CAA

[[Page 46285]]

section 112 that directs the Agency to consider malfunctions in 
determining the level ``achieved'' by the best performing sources when 
setting emission standards. As the Court has recognized, the phrase 
``average emissions limitation achieved by the best performing 12 
percent of'' sources ``says nothing about how the performance of the 
best units is to be calculated.'' Nat'l Ass'n of Clean Water Agencies 
v. EPA, 734 F.3d 1115, 1141 (D.C. Cir. 2013). While the EPA accounts 
for variability in setting emissions standards, nothing in CAA section 
112 requires the Agency to consider malfunctions as part of that 
analysis. The EPA is not required to treat a malfunction in the same 
manner as the type of variation in performance that occurs during 
routine operations of a source. A malfunction is a failure of the 
source to perform in a ``normal or usual manner'' and no statutory 
language compels the EPA to consider such events in setting CAA section 
112 standards.
    As the Court recognized in U.S. Sugar Corp, accounting for 
malfunctions in setting standards would be difficult, if not 
impossible, given the myriad different types of malfunctions that can 
occur across all sources in the category and given the difficulties 
associated with predicting or accounting for the frequency, degree, and 
duration of various malfunctions that might occur. Id. at 608 (``the 
EPA would have to conceive of a standard that could apply equally to 
the wide range of possible boiler malfunctions, ranging from an 
explosion to minor mechanical defects. Any possible standard is likely 
to be hopelessly generic to govern such a wide array of 
circumstances.'') As such, the performance of units that are 
malfunctioning is not ``reasonably'' foreseeable. See, e.g., Sierra 
Club v. EPA, 167 F.3d 658, 662 (D.C. Cir. 1999) (``The EPA typically 
has wide latitude in determining the extent of data-gathering necessary 
to solve a problem. We generally defer to an agency's decision to 
proceed on the basis of imperfect scientific information, rather than 
to 'invest the resources to conduct the perfect study.''') See also, 
Weyerhaeuser v. Costle, 590 F.2d 1011, 1058 (D.C. Cir. 1978) (``In the 
nature of things, no general limit, individual permit, or even any 
upset provision can anticipate all upset situations. After a certain 
point, the transgression of regulatory limits caused by `uncontrollable 
acts of third parties,' such as strikes, sabotage, operator 
intoxication or insanity, and a variety of other eventualities, must be 
a matter for the administrative exercise of case-by-case enforcement 
discretion, not for specification in advance by regulation.'') In 
addition, emissions during a malfunction event can be significantly 
higher than emissions at any other time of source operation. For 
example, if an air pollution control device with 99-percent removal 
goes off-line as a result of a malfunction (as might happen if, for 
example, the bags in a baghouse catch fire) and the emission unit is a 
steady state type unit that would take days to shut down, the source 
would go from 99-percent control to zero control until the control 
device was repaired. The source's emissions during the malfunction 
would be 100 times higher than during normal operations. As such, the 
emissions over a 4-day malfunction period would exceed the annual 
emissions of the source during normal operations. As this example 
illustrates, accounting for malfunctions could lead to standards that 
are not reflective of (and significantly less stringent than) levels 
that are achieved by a well-performing non-malfunctioning source. It is 
reasonable to interpret CAA section 112 to avoid such a result. The 
EPA's approach to malfunctions is consistent with CAA section 112 and 
is a reasonable interpretation of the statute.
    Although no statutory language compels the EPA to set standards for 
malfunctions, the EPA has the discretion to do so where feasible. For 
example, in the Petroleum Refinery Sector Risk and Technology Review, 
the EPA established a work practice standard for unique types of 
malfunctions that result in releases from pressure relief devices or 
emergency flaring events because we had information to determine that 
such work practices reflected the level of control that applies to the 
best performing sources (80 FR 75178, 75211-14, December 1, 2015). The 
EPA will consider whether circumstances warrant setting standards for a 
particular type of malfunction and, if so, whether the EPA has 
sufficient information to identify the relevant best performing sources 
and establish a standard for such malfunctions. We also encourage 
commenters to provide any such information.
    It is unlikely that a malfunction in the application of large 
appliance surface coatings would result in a violation of the 
standards. A malfunction would not lead to an increase in the HAP 
content of the coatings or the amount of HAP emitted from those 
coatings; therefore, it is unlikely that malfunctions at facilities 
using the compliant material or emission rate without control option 
would result in a violation in any case where compliant materials are 
used. Finally, compliance with the large appliance surface coating 
emission limits is based on a monthly compliance period, so any 
malfunction that causes a short-term increase in emissions may not 
cause a violation of the standard. Similarly, for facilities in the 
surface coating of metal furniture source category using the emission 
rate with add-on control compliance option or percent reduction 
compliance option, the short-term malfunction of an emission capture 
system or control device is also unlikely to lead to a violation if the 
owner or operator operates and maintains the affected source in a 
manner consistent with safety and good air pollution control practices 
for minimizing emissions during that malfunction. Because compliance is 
based on a monthly or a rolling 12-month compliance period, a short-
term malfunction is likely to represent only a small percent of the 
total operating time of the affected source. A single malfunction is 
also not likely to affect all of the emission units and control devices 
within the affected source. Therefore, a malfunction is not likely to 
result in a violation of the standards, and we have no information to 
suggest that it is feasible or necessary to establish any type of 
standard for malfunctions associated with the Surface Coating of Large 
Appliances or the Surface Coating of Metal Furniture source categories.
    We are requesting comment on the need to establish a standard 
during periods of malfunction for the Fabric and Other Textiles source 
category in this action, and we are seeking the specific information 
described in section IV.B.4 of this preamble to support such a 
standard. We believe a work practice standard would be appropriate for 
a malfunction at facilities in this category. We are requesting comment 
on two alternatives in this preamble. The work practice standard, if 
included in the final rule, would include the following, or similar, 
requirements.
    In the first alternative if a malfunction of a control device or a 
capture system that is used to meet the emission limits of this rule 
occurs, the facility may elect to continue operation 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. Each workstation would discontinue its application of coating 
materials onto the web, and complete drying of any coating materials 
already applied onto the web as of the start of the malfunction. 
Draining coating materials from the

[[Page 46286]]

line's applicators, or from piping, pans, or related equipment that 
deliver coating materials to the applicator, is not required. 
Deviations of a monitored parameter of a control device or enclosure 
are not malfunctions for purposes of this requirement.
    A second alternative would require that repairs be immediately 
initiated and completed as expeditiously as possible, but the line 
would not have to cease operation. We note that this source category 
compliance is based on a 12-month rolling average. Therefore, operating 
a period of time without a control device would not necessarily result 
in an exceedance of the emissions limit. However, the facility would 
not be allowed to continue to operate the coating line once it becomes 
apparent they will be unable to complete repairs before the 12-month 
rolling average compliance limit will be exceeded. We request comment 
on both of these approaches for the Fabrics and Other Textiles source 
category.
    In the unlikely event that a source fails to comply with the 
applicable CAA section 112(d) standards as a result of a malfunction 
event, the EPA will determine an appropriate response based on, among 
other things, the good faith efforts of the source to minimize 
emissions during malfunction periods, including preventative and 
corrective actions, as well as root cause analyses to ascertain and 
rectify excess emissions. The EPA will also consider whether the 
source's failure to comply with the CAA section 112(d) standard was, in 
fact, sudden, infrequent, not reasonably preventable and was not 
instead caused in part by poor maintenance or careless operation. 40 
CFR 63.2 (definition of malfunction).
    If the EPA determines in a particular case that an enforcement 
action against a source for violation of an emission standard is 
warranted, the source can raise any and all defenses in that 
enforcement action and the federal district court will determine what, 
if any, relief is appropriate. The same is true for citizen enforcement 
actions. Similarly, the presiding officer in an administrative 
proceeding can consider any defense raised and determine whether 
administrative penalties are appropriate.
    In summary, the EPA interpretation of the CAA and, in particular, 
CAA section 112 is reasonable and encourages practices that will avoid 
malfunctions. Administrative and judicial procedures for addressing 
exceedances of the standards fully recognize that violations may occur 
despite good faith efforts to comply and can accommodate those 
situations. U.S. Sugar Corp. v. EPA, 830 F.3d 579, 606-610 (2016).
2. Proposed Revisions to the General Provisions Applicability Table
 a. 40 CFR 63.4100(b) General Duty
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.6(e)(1)(i) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.6(e)(1)(i) describes the general 
duty to minimize emissions. Some of the language in that section is no 
longer necessary or appropriate in light of the elimination of the SSM 
exemption. We are proposing instead to add general duty regulatory text 
at 40 CFR 63.4100(b) that reflects the general duty to minimize 
emissions while eliminating the reference to periods covered by an SSM 
exemption. The current language in 40 CFR 63.6(e)(1)(i) characterizes 
what the general duty entails during periods of SSM. With the 
elimination of the SSM exemption, there is no need to differentiate 
between normal operations, startup and shutdown, and malfunction events 
in describing the general duty. Therefore, the language the EPA is 
proposing for 40 CFR 63.4100(b) does not include that language from 40 
CFR 63.6(e)(1).
    We are also proposing to revise the General Provisions table to 
subpart NNNN (table 2) entry for 40 CFR 63.6(e)(1)(ii) by changing the 
``yes'' in column 3 to a ``no.'' Section 63.6(e)(1)(ii) imposes 
requirements that are not necessary with the elimination of the SSM 
exemption or are redundant with the general duty requirement being 
added at 40 CFR 63.4100(b).
 b. SSM Plan
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.6(e)(3) by changing the ``yes'' in 
column 3 to a ``no.'' Generally, these paragraphs require development 
of an SSM plan and specify SSM recordkeeping and reporting requirements 
related to the SSM plan. We are also proposing to remove from 40 CFR 
part 63, subpart NNNN, the current provisions requiring the SSM plan, 
including 40 CFR 63.4100(d) and 63.4110(b)(9)(v). As noted, the EPA is 
proposing to remove the SSM exemptions. Therefore, affected units will 
be subject to an emission standard during such events. The 
applicability of a standard during such events will ensure that sources 
have ample incentive to plan for and achieve compliance, and, thus, the 
SSM plan requirements are no longer necessary.
 c. Compliance With Standards
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.6(f)(1) by changing the ``yes'' in 
column 3 to a ``no.'' The current language of 40 CFR 63.6(f)(1) exempts 
sources from non-opacity standards during periods of SSM. As discussed 
above, the Court in Sierra Club vacated the exemptions contained in 
this provision and held that the CAA requires that some CAA section 112 
standards apply continuously. Consistent with Sierra Club, the EPA is 
proposing to revise standards in this rule to apply at all times.
    We are also proposing to remove rule text in 40 CFR 63.4161(g) 
clarifying that, in calculating emissions to demonstrate compliance, 
deviation periods must include deviations during an SSM period. Since 
the EPA is removing the SSM exemption, this clarifying text is no 
longer needed.
 d. 40 CFR 63.4164 Performance Testing
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.7(e)(1) by changing the ``yes'' in 
column 3 to a ``no.'' Section 63.7(e)(1) describes performance testing 
requirements. The EPA is instead proposing to add a performance testing 
requirement at 40 CFR 63.4164. The performance testing requirements we 
are proposing to add differ from the General Provisions performance 
testing provisions in several respects. The regulatory text does not 
include the language in 40 CFR 63.7(e)(1) that restated the SSM 
exemption and language that precluded startup and shutdown periods from 
being considered ``representative'' for purposes of performance 
testing. The proposed performance testing provisions will also not 
allow performance testing during startup or shutdown. As in 40 CFR 
63.7(e)(1), performance tests conducted under this subpart should not 
be conducted during malfunctions because conditions during malfunctions 
are often not representative of normal operating conditions. Section 
63.7(e) requires that the owner or operator maintain records of the 
process information necessary to document operating conditions during 
the test and include in such records an explanation to support that 
such conditions represent normal operation. The EPA is proposing to add 
language clarifying that the owner or operator must make such records 
available to the Administrator upon request.

[[Page 46287]]

 e. Monitoring
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.8(c)(1)(i) and (iii) by changing the 
``yes'' in column 3 to a ``no.'' The cross-references to the general 
duty and SSM plan requirements in those subparagraphs are not necessary 
in light of other requirements of 40 CFR 63.8 that require good air 
pollution control practices (40 CFR 63.8(c)(1)) and that set out the 
requirements of a quality control program for monitoring equipment (40 
CFR 63.8(d)). Further, we are proposing to revise the General 
Provisions table to subpart NNNN (table 2) entry for 40 CFR 
63.8(c)(1)(ii) by changing the ``yes'' in column 3 to a ``no.'' We have 
determined that 40 CFR 63.8(c)(1)(ii) is redundant to the current 
monitoring requirement in 40 CFR 63.4168(a)(4) (i.e., ``have available 
necessary parts for routine repairs of the monitoring equipment,'' 
except 40 CFR 63.8(c)(1)(ii) specifies ``have readily available.'' We 
are proposing to revise 40 CFR 63.4168(a)(4) to specify ``readily 
available.''
 f. 40 CFR 63.4130 Recordkeeping
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(b)(2)(i) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(b)(2)(i) describes the 
recordkeeping requirements during startup and shutdown. These recording 
provisions are no longer necessary because the EPA is proposing that 
recordkeeping and reporting applicable to normal operations will apply 
to startup and shutdown. In the absence of special provisions 
applicable to startup and shutdown, such as a startup and shutdown 
plan, there is no reason to retain additional recordkeeping for startup 
and shutdown periods.
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(b)(2)(ii) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(b)(2)(ii) describes the 
recordkeeping requirements during a malfunction, requiring a record of 
``the occurrence and duration of each malfunction.'' A similar record 
is already required in 40 CFR 63.4130(j), which requires a record of 
``the date, time, and duration of each deviation,'' which the EPA is 
retaining. The regulatory text in 40 CFR 63.4130(j) differs from the 
General Provisions in that the General Provisions requires the creation 
and retention of a record of the occurrence and duration of each 
malfunction of process, air pollution control, and monitoring 
equipment; whereas 40 CFR 63.4130(j) applies to any failure to meet an 
applicable standard and is requiring that the source record the date, 
time, and duration of the failure rather than the ``occurrence.'' For 
this reason, the EPA is proposing to add to 40 CFR 63.4130(j) a 
requirement that sources also keep records that include a list of the 
affected source or equipment and actions taken to minimize emissions, 
an estimate of the quantity of each regulated pollutant emitted over 
the emission limit for which the source failed to meet the standard, 
and a description of the method used to estimate the emissions. 
Examples of such methods would include product-loss calculations, mass 
balance calculations, measurements when available, or engineering 
judgment based on known process parameters (e.g., coating HAP content 
and application rates and control device efficiencies). The EPA is 
proposing to require that sources keep records of this information to 
ensure that there is adequate information to allow the EPA to determine 
the severity of any failure to meet a standard, and to provide data 
that may document how the source met the general duty to minimize 
emissions when the source has failed to meet an applicable standard.
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(b)(2)(iv) by changing the ``yes'' 
in column 3 to a ``no.'' When applicable, the provision requires 
sources to record actions taken during SSM events when actions were 
inconsistent with their SSM plan. The requirement is no longer 
appropriate because SSM plans will no longer be required. The 
requirement previously applicable under 40 CFR 63.10(b)(2)(iv)(B) to 
record actions to minimize emissions and record corrective actions is 
now applicable by reference to 40 CFR 63.4130(j)(4).
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(b)(2)(v) by changing the ``yes'' 
in column 3 to a ``no.'' When applicable, the provision requires 
sources to record actions taken during SSM events to show that actions 
taken were consistent with their SSM plan. The requirement is no longer 
appropriate because SSM plans will no longer be required.
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(c)(15) by changing the ``yes'' in 
column 3 to a ``no.'' The EPA is proposing that 40 CFR 63.10(c)(15) no 
longer applies. When applicable, the provision allows an owner or 
operator to use the affected source's SSM plan or records kept to 
satisfy the recordkeeping requirements of the SSM plan, specified in 40 
CFR 63.6(e), to also satisfy the requirements of 40 CFR 63.10(c)(10) 
through (12). The EPA is proposing to eliminate this requirement 
because SSM plans would no longer be required, and, therefore, 40 CFR 
63.10(c)(15) no longer serves any useful purpose for affected units.
    We are proposing to remove the requirement in 40 CFR 63.4130(k)(1) 
that deviation records specify whether deviations from a standard 
occurred during a period of SSM. This revision is being proposed due to 
the proposed removal of the SSM exemption and because, as discussed 
above in this section, we are proposing that deviation records must 
specify the cause of each deviation, which could include a malfunction 
period as a cause. We are also proposing to remove the requirement to 
report the SSM records in 40 CFR 63.6(e)(3)(iii) through (v) by 
deleting 40 CFR 63.4130(k)(2).
 g. 40 CFR 63.4120 Reporting
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(d)(5) by changing the ``yes'' in 
column 3 to a ``no.'' Section 63.10(d)(5) describes the reporting 
requirements for startups, shutdowns, and malfunctions. To replace the 
General Provisions reporting requirement, the EPA is proposing to add 
reporting requirements to 40 CFR 63.4120. The replacement language 
differs from the General Provisions requirement in that it eliminates 
periodic SSM reports as a stand-alone report. We are proposing language 
that requires sources that fail to meet an applicable standard at any 
time to report the information concerning such events in the semi-
annual compliance report already required under this rule. Subpart NNNN 
currently requires reporting of the date, time period, and cause of 
each deviation. We are clarifying in the rule that, if the cause of a 
deviation from the standard is unknown, this should be specified in the 
report. We are also proposing to change ``date and time period'' to 
``date, time, and duration'' (see proposed revisions to 40 CFR 
63.4120(d)(1), (g)(6), (g)(8), and (g)(13)) to use terminology 
consistent with the recordkeeping section. Further, we are proposing 
that the report must also contain the number of deviations from the 
standard, and a list of the affected source or equipment. For deviation 
reports addressing deviations from an applicable emission limit in 40 
CFR

[[Page 46288]]

63.4090 or operating limit in Table 1 to subpart NNNN, we are proposing 
that the report also include an estimate of the quantity of each 
regulated pollutant emitted over any emission limit for which the 
source failed to meet the standard, and a description of the method 
used to estimate the emissions. For deviation reports addressing 
deviations from work practice standards associated with the emission 
rate with add-on controls option (40 CFR 63.4120(g)(13)), we are 
retaining the current requirement (including reporting actions taken to 
correct the deviation), except that we are revising the rule language 
to reference the new general duty requirement in 40 CFR 63.4100(b), we 
are clarifying that the description of the deviation must include a 
list of the affected sources or equipment and the cause of the 
deviation, we are clarifying that ``time period'' includes the ``time 
and duration,'' and we are requiring that the report include the number 
of deviations from the work practice standards in the reporting period. 
Further, we are proposing to apply these same reporting requirements to 
deviations from the proposed new equipment standards associated with 
high efficiency spray equipment (see proposed revisions in 40 CFR 
63.4120(d)(2)(vi), (e)(2), and (e)(2)(v).
    Regarding the proposed new requirement discussed above to estimate 
the quantity of each regulated pollutant emitted over any emission 
limit for which the source failed to meet the standard, and a 
description of the method used to estimate the emissions, examples of 
such methods would include product-loss calculations, mass balance 
calculations, measurements when available, or engineering judgment 
based on known process parameters (e.g., coating HAP content and 
application rates and control device efficiencies). The EPA is 
proposing this requirement to ensure that there is adequate information 
to determine compliance, to allow the EPA to determine the severity of 
the failure to meet an applicable standard, and to provide data that 
may document how the source met the general duty to minimize emissions 
during a failure to meet an applicable standard.
    We will no longer require owners or operators to determine whether 
actions taken to correct a malfunction are consistent with an SSM plan, 
because plans would no longer be required. The proposed amendments, 
therefore, eliminate 40 CFR 63.4120(j) that requires reporting of 
whether the source deviated from its SSM plan, including required 
actions to communicate with the Administrator, and the cross reference 
to 40 CFR 63.10(d)(5)(i) that contains the description of the 
previously required SSM report format and submittal schedule from this 
section. These specifications are no longer necessary because the 
events will be reported in otherwise required reports with similar 
format and submittal requirements.
    We are proposing to revise the General Provisions table to subpart 
NNNN (table 2) entry for 40 CFR 63.10(d)(5)(ii) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(d)(5)(ii) describes an immediate 
report for startups, shutdown, and malfunctions when a source failed to 
meet an applicable standard, but did not follow the SSM plan. We will 
no longer require owners and operators to report when actions taken 
during a startup, shutdown, or malfunction were not consistent with an 
SSM plan, because plans would no longer be required.
    We are proposing to remove the requirements in 40 CFR 63.4120(g)(8) 
that deviation reports must specify whether deviation from an operating 
limit occurred during a period of SSM. We are also proposing to remove 
the requirements in 40 CFR 63.4120(g)(10) to break down the total 
duration of deviations into the startup and shutdown categories. As 
discussed above in this section, we are proposing to require reporting 
of the cause of each deviation. Further, the startup and shutdown 
categories no longer apply because these periods are proposed to be 
considered normal operation, as discussed in section IV.A.4.b.1 of this 
preamble.
c. Technical Amendments to the Surface Coating of Large Appliances 
NESHAP
    We propose to amend 40 CFR 63.4166(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. Facilities using the emission rate 
with add-on control compliance option can use either EPA Method 25 or 
Method 25A to measure control device destruction efficiency. Unlike EPA 
Method 25, Method 25A does not exclude methane from the measurement of 
organic emissions. Because many exhaust streams from coating operations 
may contain methane from natural gas combustion, we are proposing to 
allow facilities the option to measure this methane using Method 18 and 
to subtract this methane from the emissions as part of their compliance 
calculations. We also propose to revise the format of references to 
test methods in 40 CFR part 60. The current reference in 40 CFR 
63.4166(a) and (b) to Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 
4, 25, and 25A specify that each method is in ``appendix A'' of part 
60. Appendix A of part 60 has been divided into appendices A-1 through 
A-8. We propose to revise each reference to appendix A to indicate 
which of the eight sections of appendix A applies to the method.
    EPA is proposing to amend 40 CFR 63.4141(a)(1)(i) and (4) to remove 
reference to paragraph (d)(4) of OSHA's Hazard Communication standard, 
which dealt with OSHA-defined carcinogens. EPA is proposing to replace 
that reference with its own list of hazardous air pollutants that must 
be regarded as potentially carcinogenic based on EPA guidelines. 
Although paragraph (d)(4) of OSHA's standard was deleted when the 
Agency adopted the Globally Harmonized System of Hazard Communication 
in 2012, it was replaced by section A.6.4.2 of mandatory Appendix A of 
that standard, which reads as follows:
    ``Where OSHA has included cancer as a health hazard to be 
considered by classifiers for a chemical covered by 29 CFR part 1910, 
subpart Z, Toxic and Hazardous Substances, chemical manufacturers, 
importers, and employers shall classify the chemical as a carcinogen.'' 
Thus, where OSHA has regulated workplace exposure to a chemical based, 
at least in part, on carcinogenic risk, OSHA requires the chemical to 
be classified as a carcinogen. OSHA suggests that EPA should refer to 
section A.6.4.2 of Appendix A of 29 CFR 1910.1200 in its discussion of 
section 63.4141 and consider chemicals that meet this requirement be 
considered ``OSHA-defined carcinogens.''
    We are proposing to replace these references to carcinogens in 29 
CFR 1910.1200(d)(4) with a list (in proposed new Table 5 to subpart 
NNNN) of those organic HAP that must be included in calculating total 
organic HAP content of a coating material if they are present at 0.1 
percent or greater by mass.
    We propose to include organic HAP in proposed Table 5 to subpart 
NNNN 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/

[[Page 46289]]

600/8-87/045, August 1987),\26\ 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).

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

    We propose to revise the monitoring provisions for thermal and 
catalytic oxidizers to clarify 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.
    We propose to renumber 40 CFR 63.4130(k)(8) and (9) to be 40 CFR 
63.4130(k)(7) and (8) because current paragraph 40 CFR 63.4130(k) is 
missing a paragraph (k)(7). This revision will address any confusion 
over this missing paragraph. We also propose to revise 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).
    Current 40 CFR 63.4931(a) allows records, ``where appropriate,'' to 
be maintained as ``electronic spreadsheets'' or a ``data base.'' We 
propose to add clarification to this provision that the allowance to 
retain electronic records applies to all records that were submitted as 
reports electronically via the EPA's CEDRI. We also propose to add text 
to the same provision clarifying that this ability to maintain 
electronic copies does not affect the requirement for facilities to 
make records, data, and reports available upon request to a delegated 
air agency or the EPA as part of an on-site compliance evaluation.
    We propose to revise various erroneous rule citations. We propose 
to revise 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 40 CFR 63.4083 is the correct citation, providing the 
compliance dates referred to in association with the erroneous rule 
citation. We propose to change the erroneous citation to ``Sec.  
63.4083.'' We propose to revise one instance in 40 CFR 63.4110(b)(10) 
of an erroneous rule citation ``Sec.  63.4081(d).'' This rule citation 
is specified in 40 CFR 63.4110(b)(10) as the source for the allowance 
to comply with the requirements of another subpart in lieu of the 
requirements of this subpart NNNN. The correct citation for this 
allowance is 40 CFR 63.4081(e), and we propose to change the erroneous 
citation to ``Sec.  63.4081(e).'' We propose to revise 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).'' This rule citation is specified 
in each 40 CFR 63.4130(f) and (g) as the source for the allowance that 
the volume solids determination is not required for coatings for which 
the mass fraction of organic HAP of the coating equals zero. However, 
it is the introductory paragraph to 40 CFR 63.4141, not 40 CFR 
63.4141(a), that provides the allowance to not be required to determine 
the volume solids for zero-HAP coatings. We propose to change the 
erroneous citation to ``Sec.  63.4141.'' We propose to revise one 
instance in 40 CFR 63.4168(c)(2) that an erroneous rule citation 
``Sec.  63.6167(b)(1) and (2)'' is specified. Section 40 CFR 
63.6167(b)(1) and (2) does not exist in 40 CFR part 63, subpart NNNN. 
Section 40 CFR 63.4167(b)(1) and (2) is the correct citation, 
describing how to establish operating limits for catalytic oxidizers as 
referred to in association with the erroneous rule citation. We propose 
to change the erroneous citation to ``Sec.  63.4167(b)(1) and (2).'' We 
propose to revise two instances in Table 2 to Subpart NNNN of Part 63 
of an erroneous rule citation ``Sec.  63.4120(b).'' This rule citation 
is specified in the fourth column of the table entry for ``Sec.  
63.10(d)(2),'' as the source for the requirements related to reporting 
results of performance tests. Section 40 CFR 63.4120(b) does not 
provide these types of requirements; however, 40 CFR 63.4120(h) 
provides these requirements. The correct citation for this allowance is 
40 CFR 63.4120(h), and we propose to change the erroneous citation to 
``Sec.  63.4120(h).'' The rule citation ``Sec.  63.4120(b)'' is also 
specified in the fourth column of the table entry for ``Sec.  
63.10(e)(3),'' as the source for the contents of periodic compliance 
reports. Section 40 CFR 63.4120(b) does not provide the contents of 
periodic compliance reports; however, 40 CFR 63.4120(g) provides these 
requirements. The correct citation for this allowance is 40 CFR 
63.4120(g), and we propose to change the erroneous citation to ``Sec.  
63.4120(g).'' Current 40 CFR 63.4152(c) requires inclusion in the 
semiannual compliance report of a statement that the source was in 
compliance with the emission limitations during the reporting period. 
We propose to add clarification to this provision that the requirement 
to submit this statement applies only if there were no deviations from 
the emission limitations.
d. Requesting Comment on Ongoing Emissions Compliance Demonstrations
    As part of an ongoing effort to improve compliance with various 
federal air emission regulations, the EPA reviewed the compliance 
demonstration requirements in the Surface Coating of Large Appliance 
NESHAP. Currently, if a source owner or operator chooses to comply with 
the standards using add-on controls, the results of an initial 
performance test are used to determine compliance; however, the rule 
does not require on-going periodic performance testing for these 
emission capture systems and add-on controls.
    As mentioned by the Institute of Clean Air Companies (ICAC) in 
their comments on proposed revisions to the NESHAP General Provisions 
(72 FR 69, January 3, 2007), ongoing maintenance and checks of control 
devices are necessary in order to ensure emissions control technology 
remains effective.\27\
---------------------------------------------------------------------------

    \27\ See Docket Item No. EPA-HQ-OAR-2004-0094-0173, available at 
www.regulations.gov. A copy of the ICAC's comments on the proposed 
revisions to the General Provisions is also included in the Large 
Appliance Docket for this action.
---------------------------------------------------------------------------

    Given these comments from ICAC, suppliers of air pollution control 
and monitoring technology, on the need for vigilance in maintaining 
equipment to stem degradation, the EPA is requesting comment on what 
steps, in addition to one-time initial emissions and capture efficiency 
testing, along with ongoing temperature measurement, might better 
ensure ongoing compliance with the standards.
    The EPA specifically is requesting comment on whether performance 
testing should be required anytime a source plans to undertake an 
operational change that may adversely affect compliance with an 
applicable standard, operating limit, or parametric monitoring value. 
Any such requirement would include provisions to allow a source to make 
the change, but limit the change to a specific time before a test is 
required. We anticipate 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. We specifically are requesting comment on this 
potential provision, including the time a source would be allowed to 
operate under the new parameters before they test, and what would 
constitute an operational change requiring testing.

[[Page 46290]]

    This approach on which we are requesting comment could also allow 
an exception from periodic testing for facilities using instruments to 
continuously measure emissions. Such continuous emissions monitoring 
systems (CEMS) would show actual emissions. Use of CEMS to demonstrate 
compliance would obviate the need for periodic oxidizer testing. 
Moreover, installation and operation of a CEMS with a timesharing 
component, such that values from more than one oxidizer exhaust could 
be tabulated in a recurring frequency, could prove less expensive 
(estimated to have an annual cost below $15,000) than ongoing oxidizer 
testing.
    The approach on which we are requesting comment would not require 
periodic testing or CEMS monitoring of facilities using the compliant 
materials option, or the emission-rate without add-on controls 
compliance option because these two compliance options do not use any 
add-on control efficiency measurements in the compliance calculations.
    The approach would require air emissions testing to measure organic 
HAP destruction or removal efficiency at the inlet and outlet of the 
add-on control device, or measurement of the control device outlet 
concentration of organic HAP. Emissions would be measured as total 
gaseous organic mass emissions as carbon using either Method 25 or 25A 
of appendix A-7 to 40 CFR part 60, which are the methods currently 
required for the initial compliance demonstration.
    We estimate that the cost to perform a control device emissions 
destruction or removal efficiency test using EPA Method 25 or 25A would 
be approximately $19,000 per control device. The cost estimate is 
included in the memorandum titled Costs/Impacts of the 40 CFR part 63 
Subparts NNNN, OOOO and RRRR Monitoring Review Revisions, in the Large 
Appliances Docket.
5. What compliance dates are we proposing?
    The EPA is proposing that affected sources that commenced 
construction or reconstruction on or before September 12, 2018 must 
comply with all of the amendments, with the exception of the proposed 
electronic format for submitting notifications and semiannual 
compliance reports, no later than 181 days after the effective date of 
the final rule. Affected sources that commence construction or 
reconstruction after September 12, 2018 must comply with all 
requirements of the subpart, including the amendments being proposed, 
with the exception of the proposed electronic format for submitting 
notifications and semiannual compliance reports, no later than the 
effective date of the final rule or upon startup, whichever is later. 
All affected facilities would have to continue to meet the current 
requirements of 40 CFR part 63, subpart NNNN until the applicable 
compliance date of the amended rule. The final action is not expected 
to be a ``major rule'' as defined by 5 U.S.C. 804(2), so the effective 
date of the final rule will be the promulgation date as specified in 
CAA section 112(d)(10).
    For existing sources, we are proposing two changes that would 
impact ongoing compliance requirements for 40 CFR part 63, subpart 
NNNN. As discussed elsewhere in this preamble, we are proposing to add 
a requirement that notifications, performance test results, and 
semiannual compliance reports be submitted electronically using the new 
template. We are also proposing to change 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. Our experience with similar industries that are 
required to convert reporting mechanisms to install necessary hardware 
and software, become familiar with the process of submitting 
performance test results electronically through the EPA's CEDRI, test 
these new electronic submission capabilities, and reliably employ 
electronic reporting shows that a time period of a minimum of 90 days, 
and, more typically, 180 days is generally necessary to successfully 
accomplish these revisions. Our experience with similar industries 
further shows that this sort of regulated facility generally requires a 
time period of 180 days to read and understand the amended rule 
requirements; to evaluate their operations to ensure that they can meet 
the standards during periods of startup and shutdown as defined in the 
rule and make any necessary adjustments; and to update their operation, 
maintenance, and monitoring plan to reflect the revised requirements. 
The EPA recognizes the confusion that multiple different compliance 
dates for individual requirements would create and the additional 
burden such an assortment of dates would impose. From our assessment of 
the timeframe needed for compliance with the entirety of the revised 
requirements, the EPA considers a period of 180 days to be the most 
expeditious compliance period practicable and, thus, is proposing that 
existing affected sources and new affected sources that commenced 
construction or reconstruction on or before September 12, 2018 be in 
compliance with all of this regulation's revised requirements, except 
for the requirement to use high efficiency spray equipment discussed 
below, within 181 days of the regulation's effective date.
    Under CAA section 112(d), we are proposing compliance dates for the 
proposed requirement to use high efficiency spray equipment if the 
source is not using the emission rate with add-on control compliance 
option. For existing affected sources under this proposed action, we 
propose to provide sources three years after the effective date of the 
final rule to comply with the proposed requirement to use high 
efficiency spray equipment. We are proposing a 3-year compliance date 
for facilities that have not switched to high efficiency spray 
equipment because facilities that are not yet using high efficiency 
spray equipment have multiple alternative equipment types to consider 
under this proposed rule. The 3-year compliance period will provide all 
facilities sufficient time to source and purchase the specific type of 
spray application equipment compatible with their operations. 
Furthermore, the compliance period provides time for sources to verify 
that the spray equipment they choose meets the transfer efficiency 
requirements in this proposed rule. In addition, because a spray gun's 
useful lifespan is approximately two years, the proposed three-year 
compliance period will provide enough time for facilities to source and 
purchase replacement guns on their current equipment purchase cycle, 
develop any necessary operational procedures, and perform training. 
Finally, the 3-year compliance period will ensure that a facility is 
not required to replace a spray gun before it has time to identify and 
source new guns and develop bid specification and operation procedures. 
For new affected sources under this proposed action, the proposed 
compliance date is the effective date of the final rule or upon 
startup, whichever is later.
    We solicit comment on these proposed compliance periods, and we 
specifically request submission of information from sources in this 
source category regarding specific actions that would need to be 
undertaken to comply with the proposed amended requirements and the 
time needed to make the adjustments for compliance with any of the 
revised requirements. We note that information provided may result in 
changes to the proposed compliance dates.

B. What are the analytical results and proposed decisions for the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category?

1. What are the results of the risk assessment and analyses?
    As described above in section III of this preamble, for the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category, we conducted a risk assessment for all HAP emitted. We 
present results of the risk assessment briefly below and in more detail 
in the Fabrics and Other Textiles Risk Assessment Report in the Fabrics 
and Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668).
a. Inhalation Risk Assessment Results
    Table 3 below provides a summary of the results of the inhalation 
risk assessment for the source category. As discussed in section 
III.C.2 of this preamble, we determined that MACT-allowable HAP 
emission levels at fabrics and other textiles printing, coating, and 
dyeing facilities are equal to 1.1 times the actual emissions. For more 
detail about the MACT-allowable emission levels, see Appendix 1 to the 
Fabrics and Other Textiles Risk Assessment Report in the Fabrics and 
Other Textiles Docket.

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

    The results of the inhalation risk modeling using actual emissions 
data, as shown in Table 3 above, indicate that the maximum individual 
cancer risk based on actual emissions (lifetime) could be up to 9-in-1 
million, 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. The total estimated 
annual cancer incidence (national) from these facilities based on 
actual emission levels is 0.002 excess cancer cases per year, or one 
case in every 500 years.
b. Acute Risk Results
    Table 3 also shows the acute risk results for the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category. The 
screening analysis for acute impacts was based on an industry-specific 
multiplier of 1.4, to estimate the peak emission rates from the average 
emission rates. For more detailed acute risk results refer to the 
Fabrics and Other Textiles Risk Assessment Report in the Fabrics and 
Other Textiles Docket.
c. Multipathway Risk Screening Results
    We did not identify any PB-HAP emitted by facilities in this source 
category. Therefore, we do not expect any human health multipathway 
risks as a result of emissions from this source category.
d. Environmental Risk Screening Results
    The emissions data for the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category indicate that no environmental HAP 
are emitted by sources within this source category. Therefore, we did 
not conduct a screening-level evaluation of the potential adverse 
environmental risks associated with emissions for the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category. We 
do not expect an adverse environmental effect as a result of HAP 
emissions from this source category.
e. Facility-Wide Risk Results
    The results of our facility-wide assessment indicate that 12 
facilities have a facility-wide cancer MIR greater than or equal to 1-
in-1 million. The maximum facility-wide cancer MIR is 9-in-1 million, 
driven by ethylene oxide from fabric finishing. The total estimated 
cancer incidence from the whole facility assessment is 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 is estimated to be 
0.3, driven by emissions of trichloroethylene from adhesive 
application.
f. What demographic groups might benefit from this regulation?
    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 km and within 50 
km of the facilities. In the analysis, we evaluated the distribution of 
HAP-related cancer and noncancer risks from the Printing, Coating, and 
Dyeing of Fabrics and Other Textiles source category across different 
demographic groups within the populations living near facilities.\28\
---------------------------------------------------------------------------

    \28\ Demographic groups included in the analysis are: White, 
African American, Native American, other races and multiracial, 
Hispanic or Latino, children 17 years of age and under, adults 18 to 
64 years of age, adults 65 years of age and over, adults without a 
high school diploma, people living below the poverty level, people 
living above the poverty level, and linguistically isolated people.
---------------------------------------------------------------------------

    The results of the demographic analysis are summarized in Table 4 
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 hazard index 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 HS 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, 
September 2017 (hereafter referred to as the Fabrics and Other Textiles 
Demographic Analysis Report), available in the Fabrics and Other 
Textiles Docket.
2. What are our proposed decisions regarding risk acceptability, ample 
margin of safety, and adverse environmental effects?
a. Risk Acceptability
    As noted in section III.A of this preamble, we weigh all health 
risk factors in our risk acceptability determination, including the 
cancer MIR, the number of persons in various cancer and noncancer risk 
ranges, cancer incidence, the maximum noncancer TOSHI, the maximum 
acute noncancer HQ, the extent of noncancer risks, the distribution of 
cancer and noncancer risks in the exposed population, and risk 
estimation uncertainties (54 FR 38044, September 14, 1989).
    For the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
source category, the risk analysis indicates that the cancer risks to 
the individual most exposed could be up to 9-in-1 million due to actual 
emissions and up to 10-in-1 million based on allowable emissions. These 
risks are considerably less than 100-in-1 million, which is the 
presumptive upper limit of acceptable risk. The risk analysis also 
shows very low cancer incidence (0.002 cases per year for actual 
emissions and allowable emissions), and we did not identify potential 
for adverse chronic noncancer health effects. The acute noncancer risks 
based on actual emissions is below an HQ of one for all facilities 
(maximum of 0.6 for formaldehyde). Therefore, we find there is little 
potential concern of acute noncancer health impacts from actual 
emissions. In addition, the risk assessment indicates no significant 
potential for multipathway health effects.
    Considering all of the health risk information and factors 
discussed above, including the uncertainties discussed in section 
III.C.7 of this preamble, we propose that the risks from the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category are 
acceptable.
b. Ample Margin of Safety Analysis
    Although we are proposing that the risks from the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category are 
acceptable, risk estimates for approximately 8,500 individuals in the 
exposed population are above 1-in-1 million at the actual emissions 
level and 10,000 individuals in the exposed population are above 1-in-1 
million at the allowable emissions level. Consequently, we further 
considered whether the MACT standards for the Printing, Coating, and

[[Page 46293]]

Dyeing of Fabrics and Other Textiles source category provide an ample 
margin of safety to protect public health. In this ample margin of 
safety analysis, we investigated available emissions control options 
that might reduce the risk from the source category. We considered this 
information along with all of the health risks and other health 
information considered in our determination of risk acceptability.
    As described in section III.B of this preamble, our technology 
review focused on identifying developments in practices, processes, and 
control technologies for the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category, and we reviewed various information 
sources regarding emission sources that are currently regulated by the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP. 
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 reported ethylene oxide emissions no longer emits this HAP as a 
result of a process change, as discussed below in the technology review 
discussion. Therefore, we are proposing that additional emissions 
controls for this source category are not necessary to provide an ample 
margin of safety.
c. Environmental Effects
    The emissions data for the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category indicate that no environmental HAP 
are emitted by sources within this source category and we are unaware 
of any adverse environmental effects caused by HAP emitted from this 
source category. Therefore, we do not expect there to be an adverse 
environmental effect as a result of HAP emissions from this source 
category and we are proposing that it is not necessary to set a more 
stringent standard to prevent, taking into consideration costs, energy, 
safety, and other relevant factors, an adverse environmental effect.
3. What are the results and proposed decisions based on our technology 
review?
    As described in section III.B of this preamble, our technology 
review focused on identifying developments in practices, processes, and 
control technologies for the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category, and the EPA reviewed various 
information sources regarding emission sources that are currently 
regulated by Fabrics and Other Textiles NESHAP. These emission sources 
include coating and printing, dyeing and finishing, and slashing of 
fabrics and other textiles. Based on our review, we identified one 
potential development in technology, a process change that eliminated 
the use of ethylene oxide at one facility. During a recent site visit 
to the facility, we learned that the ethylene oxide emissions were, in 
fact, overstated by the facility. The facility confirmed that it no 
longer uses the ethylene oxide-containing material due to cost. We note 
that this was the only facility that reported ethylene oxide emissions, 
and we conclude that ethylene oxide-containing materials are no longer 
used in the industry, based on our information. We did not identify any 
other 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. A brief 
summary of the EPA's findings in conducting the technology review of 
fabric printing, coating, and dyeing operations follows. For a detailed 
discussion of the EPA's findings, refer to the Fabrics and Other 
Textiles Technology Review Memorandum in the Fabrics and Other Textiles 
Docket.
    The technology basis for coating and printing subcategory 
operations under the original MACT standards in the Printing, Coating, 
and Dyeing of Fabrics and Other Textiles NESHAP was emission capture 
and add-on control with an overall control efficiency of 97 percent for 
existing sources and 98 percent for new or reconstructed sources. 
During development of that rulemaking, we evaluated the use of 
alternative coatings (i.e., waterborne, ultraviolet-curable, electron-
beam (EB)-curable, and thermal (a.k.a., hot-melt)) and more stringent 
standards than the MACT floor level of control for organic HAP. EB-
curable coatings are coatings that use an electron beam as the radiant 
energy source to initiate a photochemical reaction to generate a 
crosslinked network of polymer on the substrate surface. However, we 
did not adopt any of these alternatives because they were not 
universally applicable and could not achieve the needed characteristics 
for numerous types of products (67 FR 46028, July 11, 2002).
    The technology basis for dyeing and finishing subcategory 
operations at existing sources and new or reconstructed sources under 
the original MACT standards in the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles NESHAP was the use of low-HAP materials 
(i.e., the purchased materials used in the dyes and finishes applied at 
a facility). During development of that rulemaking, we found that add-
on capture and control systems for organic HAP were not used at that 
time by the industry for dyeing and finishing operations, and no 
beyond-the-floor technology was identified (67 FR 46028, July 11, 
2002).
    The technology basis for the slashing subcategory operations at 
existing sources and new or reconstructed sources under original MACT 
standards in the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP was the use of zero organic HAP materials. For these 
materials, each organic HAP that is not an OSHA-defined carcinogen that 
is measured to be present at less than one percent by weight is counted 
as zero. We found that no add-on emission capture and control systems 
for organic HAP were used by the industry. During development of that 
rulemaking, we identified no beyond-the-floor technology that could 
achieve a lower organic HAP content in materials ``as purchased'' than 
zero percent HAP (67 FR 46028, July 11, 2002).
    Using the RBLC database, we identified seven entries for facilities 
currently subject to the Printing, Coating, and Dyeing of Fabrics and 
Other Textiles NESHAP. We reviewed the state operating permits for the 
seven facilities to determine if any are using technologies that exceed 
MACT. Six of the seven permits included VOC emission limitations issued 
prior to promulgation of the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles NESHAP. All seven facilities entered in the RBLC 
database indicated they were meeting their VOC limits using solvent 
substitution, solvent reformulation, low VOC adhesives, or condensation 
controls. However, the VOC limits for four facilities were either 
annual, monthly, or daily VOC emission limits. The remaining limits for 
three facilities were VOC limits that were at least several times 
higher than the HAP content limits in 40 CFR part 63, subpart OOOO for 
the same subcategories. Because none of these limitations were more 
stringent than the HAP content limits, none of these limitations 
represented a development in practices, processes, and control 
technologies for this source category.
    Using the EPA's NEI and the ECHO databases, we identified 43 
facilities (including the seven facilities mentioned above) that are 
currently subject to the Printing, Coating, and

[[Page 46294]]

Dyeing of Fabrics and Other Textiles NESHAP. We reviewed their state 
operating permits to determine the subcategory operations being 
performed and the type of control used for those subcategories to 
comply with the NESHAP. Our review of the state operating permits found 
that the facilities using PTEs and add-on controls (e.g., carbon 
adsorbers and thermal or catalytic oxidizers) were using them only on 
fabric coating lines. We did not find any facilities in the printing, 
dyeing and finishing, or slashing subcategories using add-on controls 
for any of the other subcategories. The use of add-on controls is found 
for the same subcategories for which they were found at the time of 
MACT development. That is, facilities in the coating and printing 
subcategory are using add-on controls and facilities in the dyeing and 
finishing subcategory are using low-HAP coatings and are not using add-
on controls. (We found very few facilities that were performing both 
coating and printing and no facilities performing just printing; most 
facilities subject to 40 CFR part 63, subpart OOOO were performing 
coating, but not printing.)
    For the dyeing and finishing, and slashing subcategories, no 
facilities are using add-on controls to comply. The technology basis 
for these subcategories was the use of low-HAP (dyeing and finishing) 
and non-HAP materials (slashing). We have not identified any other 
process change or pollution prevention alternatives that could be 
applied to these two subcategories that would further reduce the 
emissions from these two subcategories.
    Finally, we identified no developments in work practices or 
procedures for the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles source category. However, we note that the one facility that 
previously reported ethylene oxide has eliminated its use through a 
process change, and we solicit comment on whether the agency should ban 
the use of ethylene oxide in this source category under the technology 
review. The current Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP requires affected sources using add-on controls as a 
compliance strategy to develop and implement a work practice plan to 
minimize organic HAP emissions from the storage, mixing, and conveying 
of coatings, thinners, and cleaning materials used in, and waste 
materials generated by, all coating operations for which emission 
limits are established. The current work practice requirements address 
all of the potential emission sources that are normally located outside 
of the PTE that is routed to the control device, and no new measures 
have been identified to further reduce the emissions from these 
sources.
    Based on a finding of no new developments in practices, processes, 
and control technologies in the technology review for printing, 
coating, and dyeing operations, we are not proposing to revise the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP 
emission limit requirements pursuant to CAA section 112(d)(6). For 
further discussion of the technology review results, refer to the 
Fabrics and Other Textiles Technology Review Memorandum in the Fabrics 
and Other Textiles Docket.
4. What other actions are we proposing?
    In the Printing, Coating, and Dyeing of Fabrics and Other Textiles 
source category, we are proposing to require electronic submittal of 
notifications, semiannual reports, and compliance reports (which 
include performance test reports). In addition, we are proposing 
revisions to the SSM provisions of the MACT rule 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 sources from the requirement to comply with otherwise 
applicable CAA section 112(d) emission standards during periods of SSM. 
We also are proposing the addition of EPA Method 18, IBR of an 
alternative test method, and various technical and editorial changes. 
Our analyses and proposed changes related to these issues are discussed 
in the sections below.
    Though we are not proposing to change reporting frequency currently 
in the rule, we are requesting comment on changing the reporting 
frequency for all reports to EPA from semi-annual to annual due to the 
potential redundancy of these reporting requirements. We recognize that 
Title V permits have a statutory requirement for semi-annual reports, 
which are generally reported to state regulatory agencies. However, we 
are not certain that changing the report frequency for just the reports 
submitted to EPA in this NESHAP will result in a reporting and 
recordkeeping burden reduction. We request comment and supporting 
information on the burden impact of changing the reporting requirement 
to annual for the reporting to EPA.
a. Electronic Reporting Requirements
    The EPA is proposing that owners and operators of facilities 
subject to the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP submit electronic copies of initial notifications 
required in 40 CFR 63.9(b), notifications of compliance status required 
in 40 CFR 63.9(h), performance test reports, and semiannual reports 
through the EPA's CDX, using the CEDRI. A description of the EPA's CDX 
and the EPA's proposed rationale and details on the addition of these 
electronic reporting requirements for the Printing, Coating, and Dyeing 
of Fabrics and Other Textiles source category is the same as for the 
Surface Coating of Large Appliances source category as discussed in 
section IV.A.4.a of this preamble. For further information regarding 
the electronic data submission process, please refer to the memorandum 
titled Electronic Reporting for Printing, Coating, and Dyeing of 
Fabrics and Other Textiles, Subpart OOOO, May 2018, in the Fabrics and 
Other Textiles Docket. No specific form is proposed at this time for 
the initial notifications required in 40 CFR 63.9(b) and notifications 
of compliance status required in 40 CFR 63.9(h). Until the EPA has 
completed electronic forms for these notifications, the notifications 
will be required to be submitted via CEDRI in PDF. After development of 
the final forms, we will notify sources about their availability via 
the CEDRI website and the Clearinghouse for Inventories and Emissions 
Factors (CHIEF) Listserv. For semiannual reports, the EPA proposes that 
owners or operators use the appropriate spreadsheet template in CEDRI 
for 40 CFR part 63, subpart OOOO, or an alternate electronic file 
format consistent with the form's extensible markup language schema. 
For further information regarding the electronic data submission 
process, please refer to the spreadsheet template attached to the 
memorandum titled Electronic Reporting Template for Printing, Coating, 
and Dyeing of Fabrics and Other Textiles, Subpart OOOO Semiannual 
Reports, May 2018, in the Fabrics and Other Textiles Docket. We 
specifically request comment on the format and usability of the 
template (e.g., filling and uploading a provided spreadsheet versus 
entering the required information into a fillable CEDRI web form), as 
well as the content, layout, and overall design of the template. Prior 
to availability of the final semiannual compliance report template in 
CEDRI, owners or operators of affected sources will be required to 
submit semiannual compliance reports as otherwise required by the 
Administrator. After development of the final template, we will notify 
sources about its availability via the CEDRI website and the CHIEF

[[Page 46295]]

Listserv.\29\ We plan to finalize a required reporting format with the 
final rule. The owner or operator would begin submitting reports 
electronically with the next report that is due, once the electronic 
template has been available for at least one year.

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

    Regarding submittal of performance test reports via EPA's ERT, as 
discussed in section IV.A.4.a of this preamble for the Surface Coating 
of Large Appliances NESHAP, the proposal to submit performance test 
data electronically to the EPA applies only if the EPA has developed an 
electronic reporting form for the test method as listed on the EPA's 
ERT website. For the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP, most of the EPA test methods (including EPA Methods 25 
and 25A) listed under 40 CFR part 63, subpart OOOO, are currently 
supported by the ERT. As discussed in section IV.A.4.a of this 
preamble, we are proposing that performance test results collected 
using test methods that are not supported by the ERT as listed on the 
EPA's ERT website at the time of the test be submitted in PDF using the 
attachment module of the ERT.
    Also, as discussed in section IV.A.4.a of this preamble for the 
Surface Coating of Large Appliances NESHAP, we are proposing to provide 
facilities with the ability to seek extensions for submitting 
electronic reports for circumstances beyond the control of the 
facility. In proposed 40 CFR 63.4311(f), we address the situation for 
facilities subject to the Printing, Coating, and Dyeing of Fabrics and 
Other Textiles NESHAP where an extension may be warranted due to 
outages of the EPA's CDX or CEDRI, which may prevent access to the 
system and submittal of the required reports. In proposed 40 CFR 
63.4311(g), we address the situation for facilities subject to the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP 
where an extension may be warranted due to a force majeure event, which 
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 compliance 
with the requirement to submit a report electronically as required by 
this rule.
b. Startup, Shutdown and Malfunction Requirements
1. Proposed Elimination of the SSM Exemption
    The EPA is proposing to eliminate the SSM exemption in the 
Printing, Coating, and Dyeing of Fabrics and Other Textiles NESHAP. The 
EPA's proposed rationale for the elimination of the SSM exemption for 
the Printing, Coating, and Dyeing of Fabrics and Other Textiles source 
category is the same as for the Surface Coating of Large Appliances 
source category, which is discussed in section IV.A.4.b.1 of this 
preamble. We are also proposing several revisions to Table 3 to subpart 
OOOO of 40 CFR part 63 (Applicability of General Provisions to Subpart 
OOOO, hereafter referred to as the ``General Provisions table to 
subpart OOOO'') as is explained in more detail below in section 
IV.B.4.b.2 of this preamble. For example, we are proposing to eliminate 
the incorporation of the General Provisions' requirement that the 
source develop an SSM plan. We are also proposing to delete 40 CFR 
63.4342(h), which specifies that deviations during SSM periods are not 
violations. Further, we are proposing to eliminate and revise certain 
recordkeeping and reporting requirements related to the SSM exemption 
as further described below. The EPA has attempted to ensure that the 
provisions we are proposing to eliminate are inappropriate, 
unnecessary, or redundant in the absence of the SSM exemption. We are 
specifically seeking comment on the specific proposed deletions and 
revisions and also whether additional provisions should be revised to 
achieve the stated goal.
    In proposing these rule amendments, the EPA has taken into account 
startup and shutdown periods and, for the same reasons explained in 
section IV.A.4.b.1 of this preamble for the Surface Coating of Large 
Appliances source category, has not proposed alternate standards for 
those periods in the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP. Although no statutory language compels the EPA to set 
standards for malfunctions, the EPA has the discretion to do so where 
feasible, as further discussed in section IV.A.4.b.1 of this preamble 
for the Surface Coating of Large Appliances source category. It is 
unlikely that a malfunction of sources in the Printing, Coating, and 
Dyeing of Fabrics and Other Textiles source category would result in a 
violation of the standards for those facilities using the compliant 
material or the emission rate without add-on controls option, since 
they meet the emission limits without using add-on controls. It also is 
unlikely that facilities using the add-on control option to meet the 
emission limits would experience a malfunction that would result in a 
violation, since compliance with the surface coating emission limits is 
based on a rolling 12-month compliance period. However, it is not 
inevitable that a malfunction would result in a violation of the 
standards for those facilities using add-on controls; therefore, we are 
considering the need for a work practice for periods of malfunction for 
these facilities. In fact, the EPA has received information that it is 
possible that a control device malfunction for sources in the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category could 
potentially result in an emissions increase and potential violation of 
the emissions limit. During these periods, it is possible that 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 wastes. In those cases, it may be appropriate 
to establish a standard for malfunctions. Given the fact that emissions 
testing during malfunctions is both economically and technically 
infeasible, we would anticipate that a separate standard would be in 
the form of a work practice standard. We are, therefore, soliciting 
information on industry 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 are also soliciting 
information on the cost savings associated with these practices. In 
addition, we are soliciting 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 are asking 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.
    In the unlikely event that a source fails to comply with the 
applicable CAA section 112(d) standards as a result of a malfunction 
event, the EPA would determine an appropriate response based on, among 
other things, the good faith efforts of the source to minimize 
emissions during malfunction periods, including preventative and 
corrective actions, as well as root cause analyses to ascertain and 
rectify excess emissions. Refer to section IV.A.4.b.1 of this preamble 
for further discussion of the EPA's actions in response to a source 
failing to comply with the applicable CAA section 112(d) standards as a 
result of a malfunction

[[Page 46296]]

event for the Surface Coating of Large Appliances source category, 
which applies to this source category.
2. Proposed Revisions to the General Provisions Applicability Table
a. 40 CFR 63.4300(b) General Duty
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.6(e)(1)(i) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.6(e)(1)(i) describes the general 
duty to minimize emissions. Some of the language in that section is no 
longer necessary or appropriate in light of the elimination of the SSM 
exemption. We are proposing instead to add general duty regulatory text 
at 40 CFR 63.4300(b) that reflects the general duty to minimize 
emissions while eliminating the reference to periods covered by an SSM 
exemption. The current language in 40 CFR 63.6(e)(1)(i) characterizes 
what the general duty entails during periods of SSM. With the 
elimination of the SSM exemption, there is no need to differentiate 
between normal operations, startup and shutdown, and malfunction events 
in describing the general duty. Therefore, the language the EPA is 
proposing for 40 CFR 63.4300(b) does not include that language from 40 
CFR 63.6(e)(1).
    We are also proposing to revise the General Provisions table to 
subpart OOOO (table 3) entry for 40 CFR 63.6(e)(1)(ii) by changing the 
``yes'' in column 3 to a ``no.'' Section 63.6(e)(1)(ii) imposes 
requirements that are not necessary with the elimination of the SSM 
exemption or are redundant with the general duty requirement being 
added at 40 CFR 63.4300(b).
b. SSM Plan
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.6(e)(3) by changing the ``yes'' in 
column 3 to a ``no.'' Generally, these paragraphs require development 
of an SSM plan and specify SSM recordkeeping and reporting requirements 
related to the SSM plan. We are also proposing to remove from 40 CFR 
part 63, subpart OOOO, the current provisions requiring the SSM plan in 
40 CFR 63.4300(c) and requiring reporting related to the SSM plan in 40 
CFR 63.4310(c)(9)(iv). As noted, the EPA is proposing to remove the SSM 
exemptions. Therefore, affected units will be subject to an emission 
standard during such events. The applicability of a standard during 
such events will ensure that sources have ample incentive to plan for 
and achieve compliance, and, thus, the SSM plan requirements are no 
longer necessary.
c. Compliance With Standards
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.6(f)(1) by changing the ``yes'' in 
column 3 to a ``no.'' The current language of 40 CFR 63.6(f)(1) exempts 
sources from non-opacity standards during periods of SSM. As discussed 
above, the Court in Sierra Club vacated the exemptions contained in 
this provision and held that the CAA requires that some CAA section 112 
standards apply continuously. Consistent with Sierra Club, the EPA is 
proposing to revise standards in this rule to apply at all times.
    We are also proposing to remove rule text in 40 CFR 63.4341(e)(4) 
and (f)(4) and 40 CFR 63.4351(d)(4) clarifying that, in calculating 
emissions to demonstrate compliance, deviation periods must include 
deviations during an SSM period. Since the EPA is removing the SSM 
exemption, this clarifying text is no longer needed.
d. 40 CFR 63.4360 Performance Testing
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.7(e)(1) by changing the ``yes'' in 
column 3 to a ``no.'' Section 63.7(e)(1) describes performance testing 
requirements. The EPA is instead proposing to add a performance testing 
requirement at 40 CFR 63.4360. The performance testing requirements we 
are proposing to add differ from the General Provisions performance 
testing provisions in several respects. The regulatory text does not 
include the language in 40 CFR 63.7(e)(1) that restated the SSM 
exemption and language that precluded startup and shutdown periods from 
being considered ``representative'' for purposes of performance 
testing. Also, the proposed performance testing provisions will not 
allow performance testing during startup or shutdown. As in 40 CFR 
63.7(e)(1), performance tests conducted under this subpart should not 
be conducted during malfunctions because conditions during malfunctions 
are often not representative of normal operating conditions. Section 
63.7(e) requires that the owner or operator maintain records of the 
process information necessary to document operating conditions during 
the test and include in such records an explanation to support that 
such conditions represent normal operation. The EPA is proposing to add 
language clarifying that the owner or operator must make such records 
available to the Administrator upon request.
e. Monitoring
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.8(c)(1)(i) and (iii) by changing the 
``yes'' in column 3 to a ``no.'' The cross-references to the general 
duty and SSM plan requirements in those subparagraphs are not necessary 
in light of other requirements of 40 CFR 63.8 that require good air 
pollution control practices (40 CFR 63.8(c)(1)) and that set out the 
requirements of a quality control program for monitoring equipment (40 
CFR 63.8(d)). Further, we are proposing to revise the General 
Provisions table to subpart NNNN (table 3) entry for 40 CFR 
63.8(c)(1)(ii) by changing the ``yes'' in column 3 to a ``no.'' We have 
determined that 40 CFR 63.8(c)(1)(ii) is redundant to the current 
monitoring requirement in 40 CFR 63.4364(a)(6) (i.e., ``maintain the 
monitoring system in proper working order including, but not limited 
to, maintaining necessary parts for routine repairs of the monitoring 
equipment''), except 40 CFR 63.8(c)(1)(ii) requires that necessary 
parts be ``readily'' available. We are proposing to revise 40 CFR 
63.4967(a)(4) to replace ``maintaining'' with specify ``keeping readily 
available.''
f. 40 CFR 63.4312 Recordkeeping
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(b)(2)(i) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(b)(2)(i) describes the 
recordkeeping requirements during startup and shutdown. These recording 
provisions are no longer necessary because the EPA is proposing that 
recordkeeping and reporting applicable to normal operations will apply 
to startup and shutdown. In the absence of special provisions 
applicable to startup and shutdown, such as a startup and shutdown 
plan, there is no reason to retain additional recordkeeping for startup 
and shutdown periods.
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(b)(2)(ii) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(b)(2)(ii) describes the 
recordkeeping requirements during a malfunction, requiring a record of 
``the occurrence and duration of each malfunction.'' A similar record 
is already required in 40 CFR 63.4312(i), which requires a record of 
``the date, time, and duration of each deviation,''

[[Page 46297]]

which the EPA is retaining. The regulatory text in 40 CFR 63.4312(i) 
differs from the General Provisions in that the General Provisions 
requires the creation and retention of a record of the occurrence and 
duration of each malfunction of process, air pollution control, and 
monitoring equipment; whereas 40 CFR 63.4312(i) applies to any failure 
to meet an applicable standard and is requiring that the source record 
the date, time, and duration of the failure rather than the 
``occurrence.'' The EPA is also proposing to add to 40 CFR 63.4312(i) a 
requirement that sources also keep records that include a list of the 
affected source or equipment and actions taken to minimize emissions, 
an estimate of the quantity of each regulated pollutant emitted over 
the emission limit for which the source failed to meet the standard, 
and a description of the method used to estimate the emissions. 
Examples of such methods would include product-loss calculations, mass 
balance calculations, measurements when available, or engineering 
judgment based on known process parameters (e.g., coating HAP content 
and application rates and control device efficiencies). We also propose 
to revise 40 CFR 63.4312(i) to clarify that, if an owner or operator 
uses the equivalent emission rate option to comply with this subpart, 
the applicable information reported as currently required in 40 CFR 
63.4311(a)(8)(ii) through (iv) satisfies the requirement to keep a 
record of the estimate of the quantity of each regulated pollutant for 
which the source failed to meet the standard and a description of the 
method used to estimate the emissions. The EPA proposes to require that 
sources keep records of this information to ensure that there is 
adequate information to allow the EPA to determine the severity of any 
failure to meet a standard, and to provide data that may document how 
the source met the general duty to minimize emissions when the source 
has failed to meet an applicable standard.
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(b)(2)(iv) by changing the ``yes'' 
in column 3 to a ``no.'' When applicable, the provision requires 
sources to record actions taken during SSM events when actions were 
inconsistent with their SSM plan. The requirement is no longer 
appropriate because SSM plans will no longer be required. The 
requirement previously applicable under 40 CFR 63.10(b)(2)(iv)(B) to 
record actions to minimize emissions and record corrective actions is 
now applicable by reference to 40 CFR 63.4312(i)(5).
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(b)(2)(v) by changing the ``yes'' 
in column 3 to a ``no.'' When applicable, the provision requires 
sources to record actions taken during SSM events to show that actions 
taken were consistent with their SSM plan. The requirement is no longer 
appropriate because SSM plans will no longer be required.
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(c)(15) by changing the ``yes'' in 
column 3 to a ``no.'' The EPA is proposing that 40 CFR 63.10(c)(15) no 
longer apply. When applicable, the provision allows an owner or 
operator to use the affected source's SSM plan or records kept to 
satisfy the recordkeeping requirements of the SSM plan, specified in 40 
CFR 63.6(e), to also satisfy the requirements of 40 CFR 63.10(c)(10) 
through (12). The EPA is proposing to eliminate this requirement 
because SSM plans would no longer be required, and, therefore, 40 CFR 
63.10(c)(15) no longer serves any useful purpose for affected units.
    We are proposing to remove the requirement in 40 CFR 63.4312(j)(1) 
that deviation records specify whether deviations from a standard 
occurred during a period of SSM. This revision is being proposed due to 
the proposed removal of the SSM exemption and because, as discussed 
above in this section, we are proposing that deviation records must 
specify the cause of each deviation, which could include a malfunction 
period as a cause. We are also proposing to remove the requirement to 
report the SSM records in 40 CFR 63.6(e)(3)(iii) through (v) by 
deleting 40 CFR 63.4312(j)(2).
g. 40 CFR 63.4311 Reporting
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(d)(5) by changing the ``yes'' in 
column 3 to a ``no.'' Section 63.10(d)(5) describes the reporting 
requirements for startups, shutdowns, and malfunctions. To replace the 
General Provisions reporting requirement, the EPA is proposing to add 
reporting requirements to 40 CFR 63.4311. The replacement language 
differs from the General Provisions requirement in that it eliminates 
periodic SSM reports as a stand-alone report. We are proposing language 
that requires sources that fail to meet an applicable standard at any 
time to report the information concerning such events in the semi-
annual compliance report already required under this rule. Subpart OOOO 
currently requires reporting of the date, time period, and cause of 
each deviation. We are clarifying in the rule that, if the cause of a 
deviation from a standard is unknown, this should be specified in the 
report. We are also proposing to change ``date and time period'' or 
``date and time'' to ``date, time, and duration'' (see proposed 
revisions to 40 CFR 63.4311(a)(7)(vii), (a)(7)(ix), and (a)(7)(xiv)) to 
use terminology consistent with the recordkeeping section. Further, we 
are proposing that the report must also contain the number of 
deviations from the standard and a list of the affected sources or 
equipment. For deviation reports addressing deviations from an 
applicable emission limit in Table 1 to subpart OOOO or operating limit 
in Table 2 to subpart OOOO, we are proposing that the report also 
include an estimate of the quantity of each regulated pollutant emitted 
over any emission limit for which the source failed to meet the 
standard, and a description of the method used to estimate the 
emissions. For deviation reports addressing deviations from work 
practice standards associated with the emission rate with add-on 
controls option (see proposed revisions to 40 CFR 63.4311(a)(7)(xiv)), 
we are retaining the current requirement (including reporting actions 
taken to correct the deviation), except that we are revising the rule 
language to reference the new general duty requirement in 40 CFR 
63.4200(b), we are clarifying that the description of the deviation 
must include a list of the affected sources or equipment and the cause 
of the deviation, we are clarifying that ``time period'' includes the 
``time and duration,'' and we are requiring that the report include the 
number of deviations from the work practice standards in the reporting 
period.
    Regarding the proposed new requirement discussed above to estimate 
the quantity of each regulated pollutant emitted over any emission 
limit for which the source failed to meet the standard, and a 
description of the method used to estimate the emissions, examples of 
such methods would include product-loss calculations, mass balance 
calculations, measurements when available, or engineering judgment 
based on known process parameters (e.g., coating HAP content and 
application rates and control device efficiencies). The EPA is 
proposing this requirement to ensure that there is adequate information 
to determine compliance, to allow the EPA to

[[Page 46298]]

determine the severity of the failure to meet an applicable standard, 
and to provide data that may document how the source met the general 
duty to minimize emissions during a failure to meet an applicable 
standard.
    We will no longer require owners or operators to determine whether 
actions taken to correct a malfunction are consistent with an SSM plan, 
because plans would no longer be required. The proposed amendments, 
therefore, eliminate 40 63.4311(c) that requires reporting of whether 
the source deviated from its SSM plan, including required actions to 
communicate with the Administrator, and the cross reference to 40 CFR 
63.10(d)(5)(i) that contains the description of the previously required 
SSM report format and submittal schedule from this section. These 
specifications are no longer necessary because the events will be 
reported in otherwise required reports with similar format and 
submittal requirements.
    We are proposing to revise the General Provisions table to subpart 
OOOO (table 3) entry for 40 CFR 63.10(d)(5)(ii) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(d)(5)(ii) describes an immediate 
report for startups, shutdown, and malfunctions when a source failed to 
meet an applicable standard, but did not follow the SSM plan. We will 
no longer require owners and operators to report when actions taken 
during a startup, shutdown, or malfunction were not consistent with an 
SSM plan, because plans would no longer be required.
    We are proposing to remove the requirements in 40 CFR 
63.4311(a)(7)(ix) that deviation reports must specify whether a 
deviation from an operating limit occurred during a period of SSM. We 
are also proposing to remove the requirements in 40 CFR 
63.4311(a)(7)(xi) to break down the total duration of deviations into 
the startup and shutdown categories. As discussed above in this 
section, we are proposing to require reporting of the cause of each 
deviation. Further, the startup and shutdown categories no longer apply 
because these periods are proposed to be considered normal operation, 
as discussed in section IV.A.4.b.1 of this preamble for the Surface 
Coating of Large Appliances source category, which also applies to this 
source category.
c. Technical Amendments to the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles NESHAP
    We propose to amend 40 CFR 63.4331, Equation 7; 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 (ppmw) to 20 
ppmv. The reference to ppmw was incorrect and inconsistent with the 
rest of the NESHAP.
    We propose to amend 40 CFR 63.4362(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. Facilities using the emission rate 
with add-on control compliance option can use either EPA Method 25 or 
Method 25A to measure control device destruction efficiency. Unlike EPA 
Method 25, Method 25A does not exclude methane from the measurement of 
organic emissions. Because exhaust streams from coating operations may 
contain methane from natural gas combustion, we are proposing to allow 
facilities the option to measure methane using Method 18 and to 
subtract the methane from the emissions as part of their compliance 
calculations. We also propose to revise the format of references to 
test methods in 40 CFR part 60. The current reference in 40 CFR 
63.4362(a) and (b) to Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 
4, 25, and 25A specify that each method is in ``appendix A'' of part 
60. Appendix A of part 60 has been divided into appendices A-1 through 
A-8. We propose to revise each reference to appendix A to indicate 
which of the eight sections of appendix A applies to the method.
    EPA is proposing to amend 40 CFR 63.4321(e)(1)(i)(A) and 
(e)(1)(iv), which describe how to demonstrate initial compliance with 
the emission limitations using the compliant material option, to remove 
reference to paragraph (d)(4) of OSHA's Hazard Communication standard, 
which dealt with OSHA-defined carcinogens. EPA is proposing to replace 
that reference with its own list of hazardous air pollutants that must 
be regarded as potentially carcinogenic based on EPA guidelines. 
Although paragraph (d)(4) of OSHA's standard was deleted when the 
Agency adopted the Globally Harmonized System of Hazard Communication 
in 2012, it was replaced by section A.6.4.2 of mandatory Appendix A of 
that standard, which reads as follows:
    ``Where OSHA has included cancer as a health hazard to be 
considered by classifiers for a chemical covered by 29 CFR part 1910, 
subpart Z, Toxic and Hazardous Substances, chemical manufacturers, 
importers, and employers shall classify the chemical as a carcinogen.'' 
Thus, where OSHA has regulated workplace exposure to a chemical based, 
at least in part, on carcinogenic risk, OSHA requires the chemical to 
be classified as a carcinogen. OSHA suggests that EPA should refer to 
section A.6.4.2 of Appendix A of 29 CFR 1910.1200 in its discussion of 
section 63.4141 and consider chemicals that meet this requirement be 
considered ``OSHA-defined carcinogens.''
    We also propose to remove the same reference in the definition of 
``No organic HAP'' in 40 CFR 63.4371. We propose to replace these 
references to OSHA-defined carcinogens at 29 CFR 1910.1200(d)(4) with a 
list (in proposed new Table 6 to subpart OOOO) of those organic HAP 
that must be included in calculating total organic HAP content of a 
coating material if they are present at 0.1 percent or greater by mass.
    We propose to include organic HAP in proposed Table 6 to subpart 
OOOO 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),\30\ 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).

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

    We propose to revise the monitoring provisions for thermal and 
catalytic oxidizers to clarify 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.
    Current 40 CFR 63.4931(a) allows records, ``where appropriate,'' to 
be maintained as ``electronic spreadsheets'' or a ``data base.'' We 
propose to add clarification to this provision that the allowance to 
retain electronic records applies to all records that were submitted as 
reports electronically via the EPA's CEDRI. We also propose to add text 
to the same provision clarifying that this ability to maintain 
electronic copies does not affect the requirement for facilities to 
make records, data, and reports available upon request to a

[[Page 46299]]

delegated air agency or the EPA as part of an on-site compliance 
evaluation.
    We propose to revise 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). Section 40 CFR 63.4342(f) requires ``If there were 
no deviations from the applicable emission limit in Table 1 to this 
subpart,'' then the source (i.e., coating/printing or dyeing/finishing 
operation) must submit a statement that the source is ``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.'' We are proposing to revise the text; ``If there 
were no deviations from the applicable emission limit in Table 1 to 
this subpart,'' to read ``If there were no deviations from the 
applicable emission limitations in Sec. Sec.  63.4290, 63.4292, and 
63.4293.'' This revised text will be consistent 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 Table 1 to this subpart and Sec. Sec.  63.4292, and 63.4293.'' Note 
that ``emission limitation'' is defined in 40 CFR 63.4371 to mean an 
emission limit, operating limit, or work practice standard.
    We propose to revise one instance in 40 CFR 63.4311(a)(7)(i)(B) and 
one instance in 40 CFR 63.4311(a)(7)(ii)(B) that reference an equation 
that is missing. Each of these provisions specifies that ``Equations 4, 
4A, 5, and 7 of Sec.  63.4331'' must be used to calculate the organic 
HAP emission rate for dyeing/finishing operations; however, Equation 6 
of Sec.  63.4331 should also be used, together with Equations 4, 4A, 5, 
and 7 of Sec.  63.4331. We propose to add ``6'' to the list of 
equations cited in 40 CFR 63.4311(a)(7)(i)(B) and 63.4311(a)(7)(ii)(B), 
so that the citation reads ``Equations 4, 4A, 5, 6, and 7 of Sec.  
63.4331.'' We propose to revise one instance in 40 CFR 63.4340(b)(3) in 
which an erroneous rule citation ``Sec.  63.4561'' is specified. 
Section 63.4561 does not exist in 40 CFR part 63, subpart OOOO, and 40 
CFR 63.4341 is the correct citation, providing the calculations for 
demonstrating initial compliance, referred to in association with the 
erroneous rule citation. We propose to change the erroneous citation to 
``Sec.  63.4341.'' We propose to revise one instance in Table 3 to 
Subpart OOOO of Part 63 of an erroneous rule reference to ``sections 
63.4342 and 63.4352.'' This rule citation is specified in the fourth 
column of the table entry for ``Sec.  63.8(g)(1)-(5),'' as the source 
for the requirements related to reducing monitoring data. Sections 40 
CFR 63.4342 and 63.4352 do not provide requirements related to data 
reduction; however, 40 CFR 63.4363 and 63.4364 do provide these 
requirements and should be the correct citation. We propose to change 
the erroneous citation to ``Sections 63.4363 and 63.4364.''
d. Requesting Comment on Ongoing Emissions Compliance Demonstrations
    As part of an ongoing effort to improve compliance with various 
federal air emission regulations, the EPA reviewed the compliance 
demonstration requirements in the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles NESHAP. Currently, if a source owner or 
operator chooses to comply with the standards using add-on controls, 
the results of an initial performance test are used to determine 
compliance; however, the rule does not require on-going periodic 
performance testing for these emission capture systems and add-on 
controls.
    As described more fully in section IV.A.4.d of this preamble for 
the Surface Coating of Large Appliances source category, the ICAC, in 
their comments on proposed revisions to the NESHAP General Provisions 
(72 FR 69, January 3, 2007), commented that ongoing maintenance and 
checks of control devices are necessary in order to ensure emissions 
control technology, including both thermal and catalytic oxidizers, 
remains effective.\31\ These same comments apply to the Printing, 
Coating, and Dyeing of Fabrics and Other Textiles source category.
---------------------------------------------------------------------------

    \31\ See Docket Item No. EPA-HQ-OAR-2004-0094-0173, available at 
www.regulations.gov. A copy of the ICAC's comments on the proposed 
revisions to the General Provisions is also included in the Fabrics 
and Other Textiles Docket for this action.
---------------------------------------------------------------------------

    Given these comments from ICAC, suppliers of air pollution control 
and monitoring technology, on the need for vigilance in maintaining 
equipment to stem degradation, the EPA is requesting comment on what 
steps, in addition to one-time initial emissions and capture efficiency 
testing, along with ongoing temperature measurement, might better 
ensure ongoing compliance with the standards.
    EPA specifically requests comment on whether air performance 
testing should be required anytime a source plans to undertake an 
operational change that may adversely affect compliance with an 
applicable standard, operating limit, or parametric monitoring value. 
This requirement would include provisions to allow a source to make the 
change, but limit the change to a specific time before a test is 
required. We anticipate 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. We are specifically requesting comment on this 
potential provision, including the time a source is allowed to operate 
under the new parameters before they test, and what would constitute an 
operational change requiring testing.
    This approach would require air emissions testing to measure 
organic HAP destruction or removal efficiency at the inlet and outlet 
of the add-on control device, or measurement of the control device 
outlet concentration of organic HAP. Emissions would be measured as 
total gaseous organic mass emissions as carbon using either Method 25 
or 25A of appendix A-7 to 40 CFR part 60, which are the methods 
currently required for the initial compliance demonstration.
    We estimate that the cost to perform a control device emissions 
destruction or removal efficiency test using EPA Method 25 or 25A would 
be approximately $19,000 per control device. The cost estimate is 
included in the memorandum titled Costs/Impacts of the 40 CFR part 63 
Subparts NNNN, OOOO and RRRR Monitoring Review Revisions, in the 
Fabrics and Other Textiles Docket.
5. What compliance dates are we proposing?
    The EPA is proposing that affected sources that commenced 
construction or reconstruction on or before September 12, 2018 must 
comply with all of the amendments, with the exception of the proposed 
electronic format for submitting notifications and semiannual 
compliance reports, no later than 181 days after the effective date of 
the final rule. Affected sources that commence construction or 
reconstruction after September 12, 2018 must comply with all 
requirements of the subpart, including the amendments being proposed, 
with the exception of the proposed electronic format for submitting 
notifications and semiannual compliance reports, no later than the 
effective date of the final rule or upon startup, whichever is later. 
All affected facilities would have to continue to meet the current 
requirements of 40 CFR

[[Page 46300]]

part 63, subpart OOOO until the applicable compliance date of the 
amended rule. The final action is not expected to be a ``major rule'' 
as defined by 5 U.S.C. 804(2), so the effective date of the final rule 
will be the promulgation date as specified in CAA section 112(d)(10).
    For existing sources, we are proposing two changes that would 
impact ongoing compliance requirements for 40 CFR part 63, subpart 
OOOO. As discussed elsewhere in this preamble, we are proposing to add 
a requirement that notifications, performance test results, and 
semiannual compliance reports be submitted electronically using the new 
template. We are also proposing to change 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. Our experience with similar industries that are 
required to convert reporting mechanisms to install necessary hardware 
and software, become familiar with the process of submitting 
performance test results electronically through the EPA's CEDRI, test 
these new electronic submission capabilities, and reliably employ 
electronic reporting shows that a time period of a minimum of 90 days, 
and, more typically, 180 days is generally necessary to successfully 
accomplish these revisions. Our experience with similar industries 
further shows that this sort of regulated facility generally requires a 
time period of 180 days to read and understand the amended rule 
requirements; to evaluate their operations to ensure that they can meet 
the standards during periods of startup and shutdown as defined in the 
rule and make any necessary adjustments; and to update their operation, 
maintenance, and monitoring plan to reflect the revised requirements. 
The EPA recognizes the confusion that multiple different compliance 
dates for individual requirements would create and the additional 
burden such an assortment of dates would impose. From our assessment of 
the timeframe needed for compliance with the entirety of the revised 
requirements, the EPA considers a period of 180 days to be the most 
expeditious compliance period practicable and, thus, is proposing that 
all affected sources that commenced construction or reconstruction on 
or before September 12, 2018 be in compliance with all of this 
regulation's revised requirements within 181 days of the regulation's 
effective date.
    We solicit comment on the proposed compliance periods, and we 
specifically request submission of information from sources in this 
source category regarding specific actions that would need to be 
undertaken to comply with the proposed amended requirements and the 
time needed to make the adjustments for compliance with any of the 
revised requirements. We note that information provided may result in 
changes to the proposed compliance dates.

C. What are the aanalytical results and proposed decisions for the 
Surface Coating of Metal Furniture source category?

1. What are the results of the risk assessment and analyses?
    As described in section III of this preamble, for the Surface 
Coating of Metal Furniture source category, we conducted a risk 
assessment for all HAP emitted. We present results of the risk 
assessment briefly below and in more detail in the Metal Furniture Risk 
Assessment Report in the Metal Furniture Docket (Docket ID No. EPA-HQ-
OAR-2017-0669).
a. Inhalation Risk Assessment Results
    Table 5 of this preamble provides a summary of the results of the 
inhalation risk assessment for the source category. As discussed in 
section III.C.2 of this preamble, we set MACT-allowable HAP emission 
levels at metal furniture coating facilities equal to 1.8 times actual 
emissions. For more detail about the MACT-allowable emission levels, 
see Appendix 1 to the Metal Furniture Risk Assessment Report in the 
Metal Furniture Docket.

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

    The results of the inhalation risk modeling using actual emissions 
data, as shown in Table 5 of this preamble, indicate that the maximum 
individual cancer risk based on actual emissions (lifetime) could be up 
to 7-in-1 million, 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. The total 
estimated annual cancer incidence (national) from these facilities 
based on actual emission levels is 0.0004 excess cancer cases per year 
or one case in every 2,500 years.
b. Acute Risk Results
    Table 5 of this preamble shows the acute risk results for the 
Surface Coating of Metal Furniture source category. The screening 
analysis for acute impacts was based on an industry specific multiplier 
of 1.8, to estimate the peak emission rates from the average rates. For 
more detailed acute risk results refer to the Metal Furniture Risk 
Assessment Report in the Metal Furniture Docket.
c. Multipathway Risk Screening Results
    We did not identify any PB-HAP emitted by facilities in this source 
category. Therefore, we do not expect any human health multipathway 
risks as a result of emissions from this source category.
d. Environmental Risk Screening Results
    The emissions data for the Surface Coating of Metal Furniture 
source category indicate that no environmental HAP are emitted by 
sources within this source category. Therefore, we did not conduct a 
screening-level evaluation of the potential adverse environmental risks 
associated with emissions for the Surface Coating of Metal Furniture 
source category. We do not expect an adverse environmental effect as a 
result

[[Page 46301]]

of HAP emissions from this source category.
e. Facility-Wide Risk Results
    Four facilities have a facility-wide cancer MIR greater than or 
equal to 1-in-1 million. The maximum facility-wide cancer MIR is 7-in-1 
million, driven by ethyl benzene. The total estimated cancer incidence 
from the whole facility is 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 of the 16 facilities in 
this source category. The maximum facility-wide TOSHI for the source 
category is estimated to be 0.1.
f. What demographic groups might benefit from this regulation?
    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 km and within 50 
km of the facilities. In the analysis, we evaluated the distribution of 
HAP-related cancer and noncancer risks from the Surface Coating of 
Metal Furniture source category across different demographic groups 
within the populations living near facilities.\32\
---------------------------------------------------------------------------

    \32\ Demographic groups included in the analysis are: White, 
African American, Native American, other races and multiracial, 
Hispanic or Latino, children 17 years of age and under, adults 18 to 
64 years of age, adults 65 years of age and over, adults without a 
high school diploma, people living below the poverty level, people 
living above the poverty level, and linguistically isolated people.
---------------------------------------------------------------------------

    The results of the demographic analysis 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 HS 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 Surface Coating of 
Metal Furniture Source Category Operations, October 2017, available in 
the Metal Furniture Docket.
2. What are our proposed decisions regarding risk acceptability, ample 
margin of safety, and adverse environmental effects?
a. Risk Acceptability
    As noted in section III.A of this preamble, we weigh all health 
risk factors in our risk acceptability determination, including the 
cancer MIR, the number of persons in various cancer and noncancer risk 
ranges, cancer incidence, the maximum noncancer TOSHI, the maximum 
acute noncancer HQ, the extent of noncancer risks, the distribution of 
cancer and noncancer risks in the exposed population, and risk 
estimation uncertainties (54 FR 38044, September 14, 1989).
    For the Surface Coating of Metal Furniture source category, the 
risk analysis indicates that the cancer risks to the individual most 
exposed could be up to 7-in-1 million due to actual emissions and up to 
10-in-1 million based on allowable emissions. These risks are 
considerably less than 100-in-1 million, which is the presumptive upper 
limit of acceptable risk. The risk analysis also shows very low cancer 
incidence (0.0004 cases per year for actual emissions, or one case in 
every

[[Page 46302]]

2,500 years, and 0.0008 cases per year for allowable emissions or one 
case in every 1,250 years), and we did not identify potential for 
adverse chronic noncancer health effects. The acute noncancer risks 
based on actual emissions is an HQ of 2 for glycol ethers. Therefore, 
we find there is little potential concern of acute noncancer health 
impacts from actual emissions. In addition, the risk assessment 
indicates no significant potential for multipathway health effects.
    Considering all of the health risk information and factors 
discussed above, including the uncertainties discussed in section 
III.C.7 of this preamble, we propose to find that the risks from the 
Surface Coating of Metal Furniture source category are acceptable.
b. Ample Margin of Safety Analysis
    Although we are proposing that the risks from the Surface Coating 
of Metal Furniture source category are acceptable, risk estimates for 
approximately 2,100 individuals in the exposed population are above 1-
in-1 million at the actual emissions level and 4,200 individuals in the 
exposed population are above 1-in-1 million at the allowable emissions 
level. Consequently, we further considered whether the MACT standards 
for the Surface Coating of Metal Furniture source category provide an 
ample margin of safety to protect public health. In this ample margin 
of safety analysis, we investigated available emissions control options 
that might further reduce the risk from the source category. This 
information was considered along with our determination of the health 
risks acceptability.
    As described in section III.B of this preamble, our technology 
review focused on identifying developments in practices, processes, and 
control technologies for the Surface Coating of Metal Furniture source 
category, and the EPA reviewed various information sources regarding 
emission sources that are currently regulated by the Surface Coating of 
Metal Furniture NESHAP.
    The only development identified in the technology review is the use 
of high-efficiency spray equipment. We estimated no costs or emissions 
reductions that would be achieved by switching to high efficiency 
application methods for this source category because we expect that 
metal furniture surface coating facilities are already using high 
efficiency coating application methods due to state VOC rules and the 
economic incentives of using more efficient application methods. As 
discussed below, however, we are proposing to require this technology 
under the technology review. We request comment on this proposed 
requirement and whether any facilities in this source category do not 
currently use high efficiency coating application methods.
    Based on our review, we did not identify any developments in add-on 
control technologies, other equipment, or work practices and procedures 
that would reduce HAP from the industry. Therefore, we are proposing 
that additional emissions controls for this source category are not 
necessary to provide an ample margin of safety.
c. Environmental Effects
    The emissions data for the Surface Coating of Metal Furniture 
source category indicate that no environmental HAP are emitted by 
sources within this source category and we are unaware of any adverse 
environmental effects caused by HAP emitted from this source category. 
Therefore, we do not expect there to be an adverse environmental effect 
as a result of HAP emissions from this source category and we are 
proposing that it is not necessary to set a more stringent standard to 
prevent, taking into consideration costs, energy, safety, and other 
relevant factors, an adverse environmental effect.
3. What are the results and proposed decisions based on our technology 
review?
    As described in section III.B of this preamble, our technology 
review focused on identifying developments in practices, processes, and 
control technologies for the Surface Coating of Metal Furniture source 
category, and the EPA reviewed various information sources regarding 
emission sources that are currently regulated by the Surface Coating of 
Metal Furniture NESHAP. These emission sources include coating mixing; 
coating application; coating curing; conveying coatings, thinners and 
cleaning materials; and waste storage and handling. Based on our 
review, we identified, as outlined below, one development in 
technology, the application of high-efficiency spray equipment, for the 
Surface Coating of Metal Furniture source category. A brief summary of 
the EPA's findings in conducting the technology review of metal 
furniture surface coating operations follows. For a detailed discussion 
of the EPA's findings, refer to the Metal Furniture Technology Review 
Memorandum in the Metal Furniture Docket.
    The technology basis for the original MACT standards for existing 
sources under the Surface Coating of Metal Furniture NESHAP was a 
combination of low-HAP liquid (high-solids and waterborne) coatings and 
cleaning solvents, and powder coatings. During development of that 
rulemaking, we found that add-on capture and control systems for 
organic HAP were rarely used by the industry at that time; of the 22 
existing sources that were the basis of the MACT analysis, only one 
source was identified as using an add-on control (a carbon adsorber/
oxidizer system).\33\ The original MACT basis for new or reconstructed 
sources under the NESHAP was the use of non-HAP coatings, including the 
use of powder coatings and the use of non-HAP liquid coatings. Under 
the final original MACT standards, new or reconstructed affected 
sources must emit no organic HAP during each compliance period. 
Existing affected sources must limit organic HAP emissions to no more 
than 0.10 kg organic HAP/liter (0.83 lb/gal) of coating solids used 
during each compliance period. The use of a PTE and add-on control was 
considered during development of the Metal Furniture NESHAP, but was 
rejected as not cost effective for the incremental emission reductions 
that would be achieved relative to the MACT floor level of control.

(NESHAP) for Source Category: Metal Furniture Surface Coating--

October 2001. Table 6-1, pp. 6-3 to 6-4.
---------------------------------------------------------------------------

    Using the RBLC database, we identified entries for two facilities 
currently subject to the Surface Coating of Metal Furniture NESHAP. We 
reviewed the state operating permits for the two facilities in the RBLC 
database, and for all other facilities known to be subject to 40 CFR 
part 63, subpart RRRR to determine if any are using technologies that 
exceed MACT or that were not considered during the development of the 
original NESHAP. None of these facilities are using add-on controls to 
comply with the Surface Coating of Metal Furniture NESHAP, and none of 
these facilities are using any other technology that exceeds MACT or 
that was not considered during the development of the original NESHAP.
    We have also found no information that any improvements in PTE and 
add-on control technology have occurred that would affect the cost 
effectiveness of a PTE and add-on control or result in additional 
emission reductions. We have not identified any changes that would 
increase the efficiency of these controls or reduce their cost. 
Therefore, the EPA does not consider the use of a PTE and add-on 
control to be a

[[Page 46303]]

development in technology for the metal furniture source category. This 
result is consistent with the technology review determinations for the 
Wood Furniture Manufacturing Operations NESHAP (75 FR 80247, December 
21, 2010) and for the Shipbuilding and Ship Repair (Surface Coating) 
NESHAP (75 FR 80239, December 21, 2010) that the incremental emissions 
reductions that would be achieved using PTE and add-on control would 
not warrant the additional cost that each existing source would incur. 
We considered PTEs and add-on controls in the development of the 
original Surface Coating of Metal Furniture NESHAP, but we rejected 
these systems as a beyond-the-floor options for MACT for the source 
category because the additional reductions, compared to a combination 
of low-HAP liquid coatings and powder coatings, would not justify the 
additional costs (67 FR 20206, at 20216, April 24, 2002). None of the 
facilities currently subject to the Metal Furniture NESHAP are using 
add-on controls, and we have not identified any add-on control 
technology or other equipment that has been developed that was not 
identified and considered during MACT standard development. Similarly, 
we have identified no improvements in add-on control technology or 
other equipment, and no change in the cost effectiveness of add-on 
controls that were identified and considered during MACT standard 
development that could result in additional emission reductions.
    We have not identified any process change or pollution prevention 
alternative that could be broadly applied to the industry and that was 
not identified or considered during development of the original Metal 
Furniture MACT standard. We reviewed other sources for information on 
recent trends in coating technology in the metal furniture industry. 
The ACA Industry Market Analysis has reported that the technology for 
non-wood (predominantly metal) furniture coating has been stable over 
the period since the NESHAP was promulgated, with a slow and steady 
increase in the use of powder and high-solids coatings. According to 
the ACA Industry Market Analysis, liquid coatings still account for 
about 75 percent of the coatings used on non-wood furniture and 
fixtures, but greater than 80 percent of the liquid coatings are high-
solids coatings. Powder coatings and high solids (lower-HAP coatings) 
were considered during development of the original NESHAP and are the 
basis for the MACT standards, so these technologies do not represent 
developments in practices, processes, or control technologies since the 
Surface Coating of Metal Furniture NESHAP was promulgated. Rather, the 
shift to use of more powder and higher solids coatings has occurred as 
an expected response to comply with the original Surface Coating of 
Metal Furniture NESHAP. The ACA Industry Market Analysis reported that 
the growth in powder coating demand has slowed since 2005, as the 
technology has matured and the powders are seen as commodities with 
little product differentiation.
    The technology review conducted for the Wood Furniture 
Manufacturing Operations NESHAP (40 CFR part 63, subpart JJ) identified 
the use of more efficient spray equipment as a development in process 
equipment, and adopted regulations preventing the use of conventional 
air-atomized spray guns. The Wood Furniture Manufacturing MACT 
identified the use of air-assisted airless spraying as a more efficient 
coating application technology.
    The Surface Coating of Metal Furniture NESHAP does not contain any 
standards specifying the type of spray equipment that must be used when 
coatings are spray-applied. Several other surface coating NESHAP 
specify that high efficiency spray guns must be used for spray applied 
coatings (i.e., 40 CFR part 63, subparts GG and JJ) or the compliance 
demonstration takes into account the transfer efficiency of the spray 
equipment, and the standards are based on high-efficiency spray 
application (e.g., 40 CFR part 63, subpart IIII). Using high-efficiency 
spray equipment increases the amount of coating applied to the 
substrate compared to conventional spray equipment and, therefore, 
reduces emissions. Many facilities complying with 40 CFR part 63, 
subpart RRRR are required by state VOC regulations in Indiana, Ohio, 
and Wisconsin to use high-efficiency spray guns for coatings that are 
spray applied. We expect that most other metal furniture surface 
coating facilities also are using high-efficiency application equipment 
for spray applied coatings as a cost saving measure 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 
expect that the high-efficiency application equipment would provide 
cost savings from an engineering perspective, we are uncertain of other 
factors that facilities may need to consider if choosing to switch to 
high-efficiency application equipment. Due to the competitive 
marketplace and the number of units going through these surface coating 
facilities, there may be facility specific operational, coating 
adherence, coating drying time, material compatibility, or other 
reasons that a facility may not have chosen to switch to high-
efficiency spray. We request comment on these and other aspects of 
facility decision making as the agency has limited information on the 
market penetration of this technology and these other factors.
    Based on these findings, we are proposing to revise 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, must be demonstrated to achieve 
transfer efficiency equivalent to or better than 65 percent. There are 
four types of high efficiency spray equipment technologies that have 
been applied in these applications that could achieve the 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 may also be used with 
documentation demonstrating at least 65 percent transfer efficiency. 
Spray application equipment sources not using the emission rate with 
add-on control compliance option, and/or using alternative spray 
application equipment technologies other than the four listed, must 
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 
may be certified by manufacturers of the spray equipment, on behalf of 
spray-applied coating operations sources, 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.'' When using these equivalency procedures and/or 
guidelines, facilities would not be required to submit an application 
with

[[Page 46304]]

the test plan or protocol to the Administrator, conduct the test in the 
presence of an Administrator's representative, or submit test results 
to the Administrator for review or approval. Instead, they would be 
required to maintain records demonstrating the transfer efficiency 
achieved, including a description of the procedures and/or guidelines 
used. We are proposing that all spray equipment used for spray-applied 
coating operations would be required to be operated according to 
company procedures, local specified operating procedures, or the 
manufacturer's specifications, whichever is determined to meet the 65 
percent transfer efficiency. Further, we are proposing 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.''
    Considering just the incremental cost of the high efficiency spray 
equipment and savings due to using less material consumption, we expect 
that all facilities have already switched to high efficiency 
application methods for the reasons discussed in the technology review 
section for surface coating of large appliances. We have not estimated 
the emissions reductions achieved by switching to high efficiency 
application methods for this source category because we expect that all 
large appliance surface coating facilities are using high efficiency 
coating application methods. However, if any facilities switch to high 
efficiency application equipment, there would likely be emission 
reductions of the same magnitude as would occur in the large appliance 
surface coating source category. For more information on the cost of 
spray gun equipment and potential HAP emission reductions, see the 
memorandum titled Impacts of Prohibiting the Use of Conventional Spray 
Guns in the Wood Manufacturing Operations Source Category (Docket ID 
Number EPA-HQ-OAR-2010-0786 EPA). Refer to section IV.A.5 of this 
preamble for a discussion of the compliance schedule for using high 
efficiency spray equipment.
    Finally, we identified no developments in work practices or 
procedures for the Surface Coating of Metal Furniture source category, 
including work practices and procedures that are currently prescribed 
in the NESHAP. The current Surface Coating of Metal Furniture NESHAP 
standards require that, if a facility uses add-on controls to comply 
with the emission limitations (and currently no facilities do this), 
the facility must develop and implement a work practice plan to 
minimize organic HAP emissions from the storage, mixing, and conveying 
of coatings, thinners, and cleaning materials used in, and waste 
materials generated by, all coating operations for which emission 
limits are established. The current work practice requirements address 
all the potential emission sources that are normally located outside of 
the PTE that is routed to the control device, and no new measures have 
been identified to further reduce the emissions from these sources.
    Refer to section IV.C.5 of this preamble for a discussion of the 
compliance schedule for using high efficiency spray equipment. For 
further discussion of the technology review results, refer to the Metal 
Furniture Technology Review Memorandum in the Metal Furniture Docket.
4. What other actions are we proposing?
    We are proposing to require electronic submittal of notifications, 
semiannual reports, and compliance reports (which include performance 
test reports). In addition, we are proposing revisions to the SSM 
provisions of the MACT rule in order to ensure that they are consistent 
with the Court decision in Sierra Club v. EPA, 551 F. 3d 1019 (DC Cir. 
2008), which vacated two provisions that exempted sources from the 
requirement to comply with otherwise applicable CAA section 112(d) 
emission standards during periods of SSM. We also are proposing the 
addition of EPA Method 18, various technical and editorial changes, and 
IBR of alternative test methods. Our analyses and proposed changes 
related to these issues are discussed in the sections below.
    Though we are not proposing to change reporting frequency currently 
in the rule, we are requesting comment on changing the reporting 
frequency for all reports to EPA from semi-annual to annual due to the 
potential redundancy of these reporting requirements. We recognize that 
Title V permits have a statutory requirement for semi-annual reports, 
which are generally reported to state regulatory agencies. However, we 
are not certain that changing the report frequency for just the reports 
submitted to EPA in this NESHAP will result in a reporting and 
recordkeeping burden reduction. We request comment and supporting 
information on the burden impact of changing the reporting requirement 
to annual for the reporting to EPA.
a. Electronic Reporting Requirements
    The EPA is proposing that owners and operators of facilities 
subject to the Surface Coating of Metal Furniture NESHAP submit 
electronic copies of initial notifications required in 40 CFR 63.9(b), 
notifications of compliance status required in 40 CFR 63.9(h), 
performance test reports, and semiannual reports through the EPA's CDX, 
using the CEDRI. A description of the EPA's CDX and the EPA's proposed 
rationale and details on the addition of these electronic reporting 
requirements for the Surface Coating of Metal Furniture source category 
is the same as for the Surface Coating of Large Appliances source 
category, which is discussed above in section IV.A.4.a of this 
preamble. For further information regarding the electronic data 
submission process, please refer to the memorandum titled Electronic 
Reporting for Surface Coatings of Metal Furniture, May 2018, in the 
Metal Furniture Docket. No specific form is proposed at this time for 
the initial notifications required in 40 CFR 63.9(b) and notifications 
of compliance status required in 40 CFR 63.9(h). Until the EPA has 
completed electronic forms for these notifications, the notifications 
will be required to be submitted via CEDRI in PDF. After development of 
the final forms, we will notify sources about their availability via 
the CEDRI website and the CHIEF Listserv. For semiannual reports, the 
EPA proposes that owners or operators use the appropriate spreadsheet 
template in CEDRI for 40 CFR part 63, subpart RRRR, or an alternate 
electronic file format consistent with the form's extensible markup 
language schema. For further information regarding the electronic data 
submission process, please refer to the spreadsheet template attached 
to the memorandum Electronic Reporting Template for Surface Coating of 
Metal Furniture, Subpart RRRR Semiannual Reports, May 2018, in the 
Metal Furniture Docket. We specifically request comment on the format 
and usability of the template (e.g., filling and uploading a provided 
spreadsheet versus entering the required information into a fillable 
CEDRI web form), as well as the content, layout, and overall design of 
the template. Prior to availability of the final semiannual compliance 
report template in CEDRI, owners or operators of affected sources will 
be required to submit semiannual compliance reports as otherwise 
required by the Administrator. After development of the final template, 
we will notify sources about its availability via the CEDRI website and 
the CHIEF

[[Page 46305]]

Listserv.\34\ We plan to finalize a required reporting format with the 
final rule. The owner or operator would begin submitting reports 
electronically with the next report that is due, once the electronic 
template has been available for at least one year.

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

    Regarding submittal of performance test reports via the EPA's ERT, 
as discussed in section IV.A.4.a of this preamble for the Surface 
Coating of Large Appliances NESHAP, the proposal to submit performance 
test data electronically to the EPA applies only if the EPA has 
developed an electronic reporting form for the test method as listed on 
the EPA's ERT website. For the Surface Coating of Metal Furniture 
NESHAP, most of the current EPA test methods listed under 40 CFR part 
63, subpart RRRR, are currently supported by the ERT, including EPA 
Methods 25 and 25A. EPA Method 18, which is proposed for measuring and 
subtracting methane from total organic compounds as measured by current 
EPA Method 25 or 25A, is not supported by ERT. As discussed in section 
IV.A.4.a of this preamble, we are proposing that performance test 
results collected using test methods that are not supported by the ERT 
as listed on the EPA's ERT website at the time of the test be submitted 
in PDF using the attachment module of the ERT.
    Also, as discussed in section IV.A.4.a of this preamble for the 
Surface Coating of Large Appliances NESHAP, we are proposing to provide 
facilities with the ability to seek extensions for submitting 
electronic reports for circumstances beyond the control of the 
facility. In proposed 40 CFR 63.4921(d), we address the situation for 
facilities subject to the Surface Coating of Metal Furniture NESHAP 
where an extension may be warranted due to outages of the EPA's CDX or 
CEDRI which may prevent access to the system and submittal of the 
required reports. In 40 CFR 63.4921(e), we address the situation for 
facilities subject to the Surface Coating of Metal Furniture NESHAP 
where an extension may be warranted due to a force majeure event, which 
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 compliance 
with the requirement to submit a report electronically as required by 
this rule.
b. Startup, Shutdown, and Malfunction Requirements
1. Proposed Elimination of the SSM Exemption
    The EPA is proposing to eliminate the SSM exemption in the Surface 
Coating of Metal Furniture NESHAP. The EPA's proposed rationale for the 
elimination of the SSM exemption for the Surface Coating of Metal 
Furniture source category is the same as for the Surface Coating of 
Large Appliances source category, which is discussed in section 
IV.A.4.b.1 of this preamble. We are also proposing several revisions to 
Table 2 to subpart RRRR of 40 CFR part 63 (Applicability of General 
Provisions to Subpart RRRR, hereafter referred to as the ``General 
Provisions table to subpart RRRR'') as is explained in more detail 
below in section IV.C.4.b.2 of this preamble. For example, we are 
proposing to eliminate the incorporation of the General Provisions' 
requirement that the source develop an SSM plan. Further, we are 
proposing to eliminate and revise certain recordkeeping and reporting 
requirements related to the SSM exemption as further described below. 
The EPA has attempted to ensure that the provisions we are proposing to 
eliminate are inappropriate, unnecessary, or redundant in the absence 
of the SSM exemption. We are specifically seeking comment on the 
specific proposed deletions and revisions and also whether additional 
provisions should be revised to achieve the stated goal.
    In proposing these rule amendments, the EPA has taken into account 
startup and shutdown periods and, for the same reasons explained in 
section IV.A.4.b.1 of this preamble for the Surface Coating of Large 
Appliances source category, has not proposed alternate standards for 
those periods in the Surface Coating of Metal Furniture NESHAP. 
Although no statutory language compels the EPA to set standards for 
malfunctions, the EPA has the discretion to do so where feasible, as 
further discussed in section IV.A.4.b.1 of this preamble for the 
Surface Coating of Large Appliances source category. Further, it is 
unlikely that a malfunction of sources in the Surface Coating of Metal 
Furniture source category would result in a violation of the standards. 
Because a malfunction of the coating operation would lead to defective 
products, it would most likely be corrected by the owner/operator as 
quickly as possible to minimize economic losses. Furthermore, a 
malfunction would not lead to an increase in the HAP content of the 
coatings or the amount of HAP emitted from those coatings; therefore, 
it is unlikely that malfunctions at facilities using the compliant 
material or emission rate without control option would result in a 
violation. Finally, compliance with the surface coating emission limits 
is based on a monthly compliance period, so any malfunction that causes 
a short-term increase in emissions may not cause a violation of the 
standard. We have no information to suggest that it is feasible or 
necessary to establish any type of standard for malfunctions associated 
with the Surface Coating of Metal Furniture source category. We 
encourage commenters to provide any such information, if available.
    In the unlikely event that a source fails to comply with the 
applicable CAA section 112(d) standards as a result of a malfunction 
event, the EPA would determine an appropriate response based on, among 
other things, the good faith efforts of the source to minimize 
emissions during malfunction periods, including preventative and 
corrective actions, as well as root cause analyses to ascertain and 
rectify excess emissions. Refer to section IV.A.4.b.1 of this preamble 
for further discussion of the EPA's actions in response to a source 
failing to comply with the applicable CAA section 112(d) standards as a 
result of a malfunction event for the Surface Coating of Large 
Appliances source category, which applies to this source category.
2. Proposed Revisions to the General Provisions Applicability Table
a. 40 CFR 63.4900(b) General Duty
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.6(e)(1)(i) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.6(e)(1)(i) describes the general 
duty to minimize emissions. Some of the language in that section is no 
longer necessary or appropriate in light of the elimination of the SSM 
exemption. We are proposing instead to add general duty regulatory text 
at 40 CFR 63.4900(b) that reflects the general duty to minimize 
emissions while eliminating the reference to periods covered by an SSM 
exemption. The current language in 40 CFR 63.6(e)(1)(i) characterizes 
what the general duty entails during periods of SSM. With the 
elimination of the SSM exemption, there is no need to differentiate 
between normal operations, startup and shutdown, and malfunction events 
in describing the general duty. Therefore, the language the EPA is 
proposing for 40 CFR 63.4900(b) does not include that language from 40 
CFR 63.6(e)(1).

[[Page 46306]]

    We are also proposing to revise the General Provisions table to 
subpart RRRR (table 2) entry for 40 CFR 63.6(e)(1)(ii) by changing the 
``yes'' in column 3 to a ``no.'' Section 63.6(e)(1)(ii) imposes 
requirements that are not necessary with the elimination of the SSM 
exemption or are redundant with the general duty requirement being 
added at 40 CFR 63.4900(b).
b. SSM Plan
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.6(e)(3) by changing the ``yes'' in 
column 3 to a ``no.'' Generally, these paragraphs require development 
of an SSM plan and specify SSM recordkeeping and reporting requirements 
related to the SSM plan. We are also proposing to remove from 40 CFR 
part 63, subpart RRRR, the current provisions requiring the SSM plan, 
including 40 CFR 63.4900(c) and 63.4910(c)(9)(v). As noted, the EPA is 
proposing to remove the SSM exemptions. Therefore, affected units will 
be subject to an emission standard during such events. The 
applicability of a standard during such events will ensure that sources 
have ample incentive to plan for and achieve compliance and thus the 
SSM plan requirements are no longer necessary.
c. Compliance With Standards
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.6(f)(1) by changing the ``yes'' in 
column 3 to a ``no.'' The current language of 40 CFR 63.6(f)(1) exempts 
sources from non-opacity standards during periods of SSM. As discussed 
above, the Court in Sierra Club vacated the exemptions contained in 
this provision and held that the CAA requires that some CAA section 112 
standards apply continuously. Consistent with Sierra Club, the EPA is 
proposing to revise standards in this rule to apply at all times.
    We are also proposing to remove rule text in 40 CFR 63.4961(h) 
clarifying that, in calculating emissions to demonstrate compliance, 
deviation periods must include deviations during an SSM period. Since 
the EPA is removing the SSM exemption, this clarifying text is no 
longer needed.
d. 40 CFR 63.4963 Performance Testing
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.7(e)(1) by changing the ``yes'' in 
column 3 to a ``no.'' Section 63.7(e)(1) describes performance testing 
requirements. The EPA is instead proposing to add a performance testing 
requirement at 40 CFR 63.4963. We are also proposing to remove rule 
text in 40 CFR 63.4963(a)(1) that states that periods of malfunction do 
not constitute representative conditions for the purposes of conducting 
a performance test. The performance testing requirements we are 
proposing differ from the General Provisions performance testing 
provisions in several respects. The regulatory text does not include 
the language in 40 CFR 63.7(e)(1) that restated the SSM exemption and 
language that precluded startup and shutdown periods from being 
considered ``representative'' for purposes of performance testing. 
Also, the proposed performance testing provisions will not allow 
performance testing during startup or shutdown. As in 40 CFR 
63.7(e)(1), performance tests conducted under this subpart should not 
be conducted during malfunctions because conditions during malfunctions 
are often not representative of normal operating conditions. Section 
63.7(e) requires that the owner or operator maintain records of the 
process information necessary to document operating conditions during 
the test and include in such records an explanation to support that 
such conditions represent normal operation. The EPA is proposing to add 
language clarifying that the owner or operator must make such records 
available to the Administrator upon request.
e. Monitoring
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.8(c)(1)(i) and (iii) by changing the 
``yes'' in column 3 to a ``no.'' The cross-references to the general 
duty and SSM plan requirements in those subparagraphs are not necessary 
in light of other requirements of 40 CFR 63.8 that require good air 
pollution control practices (40 CFR 63.8(c)(1)) and that set out the 
requirements of a quality control program for monitoring equipment (40 
CFR 63.8(d)). Further, we are proposing to revise the General 
Provisions table to subpart NNNN (table 2) entry for 40 CFR 
63.8(c)(1)(ii) by changing the ``yes'' in column 3 to a ``no.'' We have 
determined that 40 CFR 63.8(c)(1)(ii) is redundant to the current 
monitoring requirement in 40 CFR 63.4967(a)(4) (i.e., ``maintain the 
CPMS at all times and have available necessary parts for routine 
repairs of the monitoring equipment''), except 40 CFR 63.8(c)(1)(ii) 
specifies ``readily available.'' We are proposing to revise 40 CFR 
63.4967(a)(4) to specify ``readily available.''
f. 40 CFR 63.4930 Recordkeeping
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(b)(2)(i) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(b)(2)(i) describes the 
recordkeeping requirements during startup and shutdown. These recording 
provisions are no longer necessary because the EPA is proposing that 
recordkeeping and reporting applicable to normal operations will apply 
to startup and shutdown. In the absence of special provisions 
applicable to startup and shutdown, such as a startup and shutdown 
plan, there is no reason to retain additional recordkeeping for startup 
and shutdown periods.
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(b)(2)(ii) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(b)(2)(ii) describes the 
recordkeeping requirements during a malfunction, requiring a record of 
``the occurrence and duration of each malfunction.'' A similar record 
is already required in 40 CFR 63.4930(j), which requires a record of 
``the date, time, and duration of each deviation,'' which the EPA is 
retaining. The regulatory text in 40 CFR 63.4930(j) differs from the 
General Provisions in that the General Provisions requires the creation 
and retention of a record of the occurrence and duration of each 
malfunction of process, air pollution control, and monitoring 
equipment; whereas 40 CFR 63.4930(j) applies to any failure to meet an 
applicable standard and is requiring that the source record the date, 
time, and duration of the failure rather than the ``occurrence.'' The 
EPA is also proposing to add to 40 CFR 63.4930(j) a requirement that 
sources also keep records that include a list of the affected source or 
equipment and actions taken to minimize emissions, an estimate of the 
quantity of each regulated pollutant emitted over the emission limit 
for which the source failed to meet the standard, and a description of 
the method used to estimate the emissions. Examples of such methods 
would include product-loss calculations, mass balance calculations, 
measurements when available, or engineering judgment based on known 
process parameters (e.g., coating HAP content and application rates and 
control device efficiencies). The EPA is proposing to require that 
sources keep records of this information to ensure that there is

[[Page 46307]]

adequate information to allow the EPA to determine the severity of any 
failure to meet a standard, and to provide data that may document how 
the source met the general duty to minimize emissions when the source 
has failed to meet an applicable standard.
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(b)(2)(iv) by changing the ``yes'' 
in column 3 to a ``no.'' When applicable, the provision requires 
sources to record actions taken during SSM events when actions were 
inconsistent with their SSM plan. The requirement is no longer 
appropriate because SSM plans will no longer be required. The 
requirement previously applicable under 40 CFR 63.10(b)(2)(iv)(B) to 
record actions to minimize emissions and record corrective actions is 
now applicable by reference to 40 CFR 63.4930(j)(4).
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(b)(2)(v) by changing the ``yes'' 
in column 3 to a ``no.'' When applicable, the provision requires 
sources to record actions taken during SSM events to show that actions 
taken were consistent with their SSM plan. The requirement is no longer 
appropriate because SSM plans will no longer be required.
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(c)(15) by changing the ``yes'' in 
column 3 to a ``no.'' The EPA is proposing that 40 CFR 63.10(c)(15) no 
longer apply. When applicable, the provision allows an owner or 
operator to use the affected source's SSM plan or records kept to 
satisfy the recordkeeping requirements of the SSM plan, specified in 40 
CFR 63.6(e), to also satisfy the requirements of 40 CFR 63.10(c)(10) 
through (12). The EPA is proposing to eliminate this requirement 
because SSM plans would no longer be required, and, therefore, 40 CFR 
63.10(c)(15) no longer serves any useful purpose for affected units.
    We are proposing to remove the requirement in 40 CFR 63.4930(k)(1) 
that deviation records specify whether deviations from a standard 
occurred during a period of SSM. This revision is being proposed due to 
the proposed removal of the SSM exemption and because, as discussed 
above in this section, we are proposing that deviation records must 
specify the cause of each deviation, which could include a malfunction 
period as a cause. We are also proposing to remove the requirement to 
report the SSM records in 40 CFR 63.6(e)(3)(iii) through (v) by 
deleting 40 CFR 63.4930(k)(2).
g. 40 CFR 63.4920 Reporting
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(d)(5) by changing the ``yes'' in 
column 3 to a ``no.'' Section 63.10(d)(5) describes the reporting 
requirements for startups, shutdowns, and malfunctions. To replace the 
General Provisions reporting requirement, the EPA is proposing to add 
reporting requirements to 40 CFR 63.4920. The replacement language 
differs from the General Provisions requirement in that it eliminates 
periodic SSM reports as a stand-alone report. We are proposing language 
that requires sources that fail to meet an applicable standard at any 
time to report the information concerning such events in the semi-
annual compliance report already required under this rule. Subpart RRRR 
of 40 CFR subpart 63 currently requires reporting of the date, time 
period, and cause of each deviation. We are clarifying in the rule 
that, if the cause of a deviation from the standard is unknown, this 
should be specified in the report. We are also proposing to change 
``date and time period'' or ``date and time'' to ``date, time, and 
duration'' (see 40 CFR 63.4920(a)(5)(i), (a)(7)(ix), and (a)(7)(xi), 
(a)(7)(xvi)) to use terminology consistent with the recordkeeping 
section. Further, we are proposing that the report must also contain 
the number of deviations from the standard and a list of the affected 
source or equipment. For deviation reports addressing deviations from 
an applicable emission limit in 40 CFR 63.4890 or operating limit in 
Table 1 to subpart RRRR, we are proposing that the report also include 
an estimate of the quantity of each regulated pollutant emitted over 
any emission limit for which the source failed to meet the standard, 
and a description of the method used to estimate the emissions. For 
deviation reports addressing deviations from work practice standards 
associated with the emission rate with add-on controls option (see 
proposed revisions to 40 CFR 63.4920(a)(7)(xvi)), we are retaining the 
current requirement (including reporting actions taken to correct the 
deviation), except that we are revising the rule language to reference 
the new general duty requirement in 40 CFR 63.4900(b), we are 
clarifying that the description of the deviation must include a list of 
the affected sources or equipment and the cause of the deviation, we 
are clarifying that ``time period'' includes the ``time and duration,'' 
and we are requiring that the report include the number of deviations 
from the work practice standards in the reporting period. Further, we 
are proposing to apply these same reporting requirements to deviations 
from the proposed new equipment standards associated with high 
efficiency spray equipment (see proposed revisions in 40 CFR 
63.4920(a)(5)(ii), (a)(5)(ii)(F), and (a)(5)(ii)(G)).
    Regarding the proposed new requirement discussed above to estimate 
the quantity of each regulated pollutant emitted over any emission 
limit for which the source failed to meet the standard, and a 
description of the method used to estimate the emissions, examples of 
such methods would include product-loss calculations, mass balance 
calculations, measurements when available, or engineering judgment 
based on known process parameters (e.g., coating HAP content and 
application rates and control device efficiencies). The EPA is 
proposing this requirement to ensure that there is adequate information 
to determine compliance, to allow the EPA to determine the severity of 
the failure to meet an applicable standard, and to provide data that 
may document how the source met the general duty to minimize emissions 
during a failure to meet an applicable standard.
    We will no longer require owners or operators to determine whether 
actions taken to correct a malfunction are consistent with an SSM plan, 
because plans would no longer be required. The proposed amendments, 
therefore, eliminate 40 CFR 63.4920(c) that requires reporting of 
whether the source deviated from its SSM plan, including required 
actions to communicate with the Administrator, and the cross reference 
to 40 CFR 63.10(d)(5)(i) that contains the description of the 
previously required SSM report format and submittal schedule from this 
section. These specifications are no longer necessary because the 
events will be reported in otherwise required reports with similar 
format and submittal requirements.
    We are proposing to revise the General Provisions table to subpart 
RRRR (table 2) entry for 40 CFR 63.10(d)(5)(ii) by changing the ``yes'' 
in column 3 to a ``no.'' Section 63.10(d)(5)(ii) describes an immediate 
report for startups, shutdown, and malfunctions when a source failed to 
meet an applicable standard, but did not follow the SSM plan. We will 
no longer require owners and operators to report when actions taken 
during a startup, shutdown, or malfunction were not consistent with an 
SSM plan, because plans would no longer be required.

[[Page 46308]]

    We are proposing to remove the requirements in 40 CFR 
63.4920(a)(7)(xiii) that deviation reports must specify whether a 
deviation from an operating limit occurred during a period of SSM. We 
are also proposing to remove the requirements in 40 CFR 
63.4920(a)(7)(xi) to break down the total duration of deviations into 
the startup and shutdown categories. As discussed above in this 
section, we are proposing to require reporting of the cause of each 
deviation. Further, the startup and shutdown categories no longer apply 
because these periods are proposed to be considered normal operation, 
as discussed in section IV.C.4.b.1 of this preamble for the Surface 
Coating of Large Appliances source category, which also applies to this 
source category.
c. Technical Amendments to the Surface Coating of Metal Furniture 
NESHAP
    We are proposing to amend 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. Facilities using the emission rate 
with add-on control compliance option can use either EPA Method 25 or 
Method 25A to measure control device destruction efficiency. Unlike EPA 
Method 25, Method 25A does not exclude methane from the measurement of 
organic emissions. Because many exhaust streams from coating operations 
may contain methane from natural gas combustion, we are proposing to 
allow facilities the option to measure the methane using Method 18 and 
to subtract it from the emissions as part of their compliance 
calculations. We also propose to revise the format of references to 
test methods in 40 CFR part 60. The current reference in 40 CFR 
63.4965(a) and (b) to Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 
4, 25, and 25A specify that each method is in ``appendix A'' of part 
60. Appendix A of part 60 has been divided into appendices A-1 through 
A-8. We propose to revise each reference to appendix A to indicate 
which of the eight sections of appendix A applies to the method.
    EPA is proposing to amend 40 CFR 63.4941(a)(1)(i) and (a)(4), which 
describe how to demonstrate initial compliance with the emission 
limitations using the compliant material option, to remove reference to 
paragraph (d)(4) of OSHA's Hazard Communication standard, which dealt 
with OSHA-defined carcinogens. EPA is proposing to replace that 
reference with its own list of hazardous air pollutants that must be 
regarded as potentially carcinogenic based on EPA guidelines. Although 
paragraph (d)(4) of OSHA's standard was deleted when the Agency adopted 
the Globally Harmonized System of Hazard Communication in 2012, it was 
replaced by section A.6.4.2 of mandatory Appendix A of that standard, 
which reads as follows:
    ``Where OSHA has included cancer as a health hazard to be 
considered by classifiers for a chemical covered by 29 CFR part 1910, 
subpart Z, Toxic and Hazardous Substances, chemical manufacturers, 
importers, and employers shall classify the chemical as a carcinogen.'' 
Thus, where OSHA has regulated workplace exposure to a chemical based, 
at least in part, on carcinogenic risk, OSHA requires the chemical to 
be classified as a carcinogen. OSHA suggests that EPA should refer to 
section A.6.4.2 of Appendix A of 29 CFR 1910.1200 in its discussion of 
section 63.4141 and consider chemicals that meet this requirement be 
considered ``OSHA-defined carcinogens.''
    We are proposing to replace these references to OSHA-defined 
carcinogens at 29 CFR 1910.1200(d)(4) with a list (in proposed new 
Table 5 to 40 CFR part 63, subpart RRRR) of those organic HAP that must 
be included in calculating total organic HAP content of a coating 
material if they are present at 0.1 percent or greater by mass.
    We are including organic HAP in the proposed Table 5 to 40 CFR part 
63, subpart RRRR 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),\35\ 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).
---------------------------------------------------------------------------

    \35\ See https://www.epa.gov/fera/dose-response-assessment-assessing-health-risks-associated-exposure-hazardous-air-pollutants.
---------------------------------------------------------------------------

    We are also proposing to revise the monitoring provisions for 
thermal and catalytic oxidizers to clarify 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.
    Current 40 CFR 63.4931(a) allows records, ``where appropriate,'' to 
be maintained as ``electronic spreadsheets'' or a ``data base.'' We 
propose to add clarification to this provision that the allowance to 
retain electronic records applies to all records that were submitted as 
reports electronically via the EPA's CEDRI. We also propose to add text 
to the same provision clarifying that this ability to maintain 
electronic copies does not affect the requirement for facilities to 
make records, data, and reports available upon request to a delegated 
air agency or the EPA as part of an on-site compliance evaluation.
    We propose to revise the second sentence of 40 CFR 63.4920(a)(4) to 
correct an erroneous reference to ``the emission limitations in Sec.  
63.4890,'' to be ``the applicable emission limitations in Sec. Sec.  
63.4890, 63.4892, and 63.4893.'' This provision is intended to provide 
the criteria for all compliance options, for making a statement that 
there were no deviations in the compliance period. For this provision 
to apply to the emission rate with add-on control devices option cited 
later in the sentence in ``Sec.  63.4962(f),'' the criteria for making 
an affirmative statement of no deviations must address all three types 
of emission limitations (as defined in 40 CFR 63.4981) in 40 CFR 
63.4890, 63.4892, and 63.4893. To avoid confusion with the term 
``emission limitation'' as defined in 40 CFR 63.4981, and harmonize the 
terminology with 40 CFR 63.4890, we also propose to change ``emission 
limitation'' in the first sentence of 40 CFR 63.4920(a)(4) to be 
``emission limit.''
    We propose to remove from 40 CFR 63.4951(c) the list of methods 
that may be used to determine the density of each coating, thinner, and 
cleaning material, and to retain the reference to 40 CFR 63.4941(c), 
which provides the same list of methods. This list of methods is being 
updated in 40 CFR 63.4941(c), including IBR of a new version of a 
method, and this proposed approach minimizes redundancy in the rule and 
removes the need to incorporate the revised method into two separate 
provisions of the subpart.
    We propose to revise one instance in Table 2 to Subpart RRRR of 
Part 63 of an erroneous rule citation of ``Sec.  63.4920(a).'' This 
rule citation is specified in the fourth column of the table entry for 
``Sec.  63.10(e)(3),''as the source for the contents of periodic 
compliance reports. Section 40 CFR 63.4920(a) does not provide the 
contents of periodic compliance reports; they are provided in 40 CFR 
63.4920(b), and we propose to change the erroneous citation to ``Sec.  
63.4920(b).''

[[Page 46309]]

d. Requesting Comment on Ongoing Emissions Compliance Demonstrations
    As part of an ongoing effort to improve compliance with various 
federal air emission regulations, the EPA reviewed the compliance 
demonstration requirements in the Surface Coating of Metal Furniture 
NESHAP. Currently, if a source owner or operator chooses to comply with 
the standards using add-on controls, the results of an initial 
performance test are used to determine compliance; however, the rule 
does not require on-going periodic performance testing for these 
emission capture systems and add-on controls.
    As described more fully in section IV.A.4.d of this preamble for 
the Surface Coating of Large Appliances source category, the ICAC, in 
their comments on proposed revisions to the NESHAP General Provisions 
(72 FR 69, January 3, 2007), commented that ongoing maintenance and 
checks of control devices are necessary in order to ensure emissions 
control technology, including both thermal and catalytic oxidizers, 
remains effective.\36\ These same comments apply to the Surface Coating 
of Metal Furniture source category.
---------------------------------------------------------------------------

    \36\ See Docket EPA-HQ-OAR-2004-0094-0173, available at 
www.regulations.gov. A copy of the ICAC's comments on the proposed 
revisions to the General Provisions is also included in the Metal 
Furniture Docket for this action.
---------------------------------------------------------------------------

    Given these comments from ICAC, suppliers of air pollution control 
and monitoring technology, on the need for vigilance in maintaining 
equipment to stem degradation, the EPA is requesting comment on what 
steps, in addition to one-time initial emissions and capture efficiency 
testing, along with ongoing temperature measurement, might better 
ensure ongoing compliance with the standards.
    One approach on which the EPA is specifically requesting comment, 
but which is not included in this proposed rule, would be to require 
air performance testing anytime a source plans to undertake an 
operational change that may adversely affect compliance with an 
applicable standard, operating limit, or parametric monitoring value. 
This requirement would include provisions to allow a source to make the 
change, but limit the change to a specific time before a test is 
required. We anticipate 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. We are specifically requesting comment on this 
potential provision, including the time a source is allowed to operate 
under the new parameters before they test, and what would constitute an 
operational change requiring testing.
    This approach on which we are requesting comment could also allow 
an exception from periodic testing for facilities using instruments to 
continuously measure emissions. Such CEMS would show actual emissions. 
Use of CEMS to demonstrate compliance would obviate the need for 
periodic oxidizer testing. Moreover, installation and operation of a 
CEMS with a timesharing component, such that values from more than one 
oxidizer exhaust could be tabulated in a recurring frequency, could 
prove less expensive (estimated to have an annual cost below $15,000) 
than ongoing oxidizer testing.
    Of course, this approach on which we are requesting comment would 
not require periodic testing or CEMS monitoring of facilities using the 
compliant materials option, or the emission-rate without add-on 
controls compliance option because these two compliance options do not 
use any add-on control efficiency measurements in the compliance 
calculations.
    This approach would require air emissions testing to measure 
organic HAP destruction or removal efficiency at the inlet and outlet 
of the add-on control device, or measurement of the control device 
outlet concentration of organic HAP. Emissions would be measured as 
total gaseous organic mass emissions as carbon using either Method 25 
or 25A of appendix A-7 to 40 CFR part 60, which are the methods 
currently required for the initial compliance demonstration.
    We estimate that the cost to perform a control device emissions 
destruction or removal efficiency test using EPA Method 25 or 25A would 
be approximately $19,000 per control device. The cost estimate is 
included in the memorandum titled Costs/Impacts of the 40 CFR part 63 
Subparts NNNN, OOOO and RRRR Monitoring Review Revisions, in the Metal 
Furniture Docket.
5. What compliance dates are we proposing?
    The EPA is proposing that affected sources that commenced 
construction or reconstruction on or before September 12, 2018 must 
comply with all of the amendments, with the exception of the proposed 
electronic format for submitting notifications and semiannual 
compliance reports, no later than 181 days after the effective date of 
the final rule. Affected sources that commence construction or 
reconstruction after September 12, 2018 must comply with all 
requirements of the subpart, including the amendments being proposed, 
with the exception of the proposed electronic format for submitting 
notifications and semiannual compliance reports, no later than the 
effective date of the final rule or upon startup, whichever is later. 
All affected facilities would have to continue to meet the current 
requirements of 40 CFR part 63, subpart RRRR until the applicable 
compliance date of the amended rule. The final action is not expected 
to be a ``major rule'' as defined by 5 U.S.C. 804(2), so the effective 
date of the final rule will be the promulgation date as specified in 
CAA section 112(d)(10).
    For existing sources, we are proposing two changes that would 
impact ongoing compliance requirements for 40 CFR part 63, subpart 
RRRR. As discussed elsewhere in this preamble, we are proposing to add 
a requirement that notifications, performance test results, and 
semiannual compliance reports be submitted electronically using the new 
template. We are also proposing to change 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. Our experience with similar industries that are 
required to convert reporting mechanisms to install necessary hardware 
and software, become familiar with the process of submitting 
performance test results electronically through the EPA's CEDRI, test 
these new electronic submission capabilities, and reliably employ 
electronic reporting shows that a time period of a minimum of 90 days, 
and, more typically, 180 days is generally necessary to successfully 
accomplish these revisions. Our experience with similar industries 
further shows that this sort of regulated facility generally requires a 
time period of 180 days to read and understand the amended rule 
requirements; to evaluate their operations to ensure that they can meet 
the standards during periods of startup and shutdown as defined in the 
rule and make any necessary adjustments; and to update their operation, 
maintenance, and monitoring plan to reflect the revised requirements. 
The EPA recognizes the confusion that multiple different compliance 
dates for individual requirements would create and the additional 
burden such an assortment of dates would impose. From

[[Page 46310]]

our assessment of the timeframe needed for compliance with the entirety 
of the revised requirements, the EPA considers a period of 180 days to 
be the most expeditious compliance period practicable and, thus, is 
proposing that existing affected sources and new affected sources that 
commenced construction or reconstruction on or before September 12, 
2018 be in compliance with all of this regulation's revised 
requirements, except for the requirement to use high efficiency spray 
equipment discussed below, within 181 days of the regulation's 
effective date.
    Under CAA section 112(d), we are proposing compliance dates for the 
proposed requirement to use high efficiency spray equipment if the 
source is not using the emission rate with add-on control compliance 
option. For existing affected sources under this proposed action, we 
propose to provide sources three years after the effective date of the 
final rule to comply with the proposed requirement to use high 
efficiency spray equipment. We are proposing a three-year compliance 
date for facilities that have not switched to high efficiency spray 
equipment because facilities that are not yet using high efficiency 
spray equipment have multiple alternative equipment types to consider 
under this proposed rule. The three-year compliance period will provide 
all facilities sufficient time to source and purchase the specific type 
of spray application equipment compatible with their operations. 
Furthermore, the compliance period provides time for sources to verify 
that the spray equipment they choose meets the transfer efficiency 
requirements in this proposed rule. In addition, because a spray gun's 
useful lifespan is approximately two years, the proposed three-year 
compliance period will provide enough time for facilities to source and 
purchase replacement guns on their current equipment purchase cycle, 
develop any necessary operational procedures, and perform training. 
Finally, the three-year compliance period will ensure that a facility 
is not required to replace a spray gun before it has time to identify 
and source new guns and develop bid specification and operation 
procedures. For new affected sources under this proposed action, the 
proposed compliance date is the effective date of the final rule or 
upon startup, whichever is later. We solicit comment on these proposed 
compliance periods, and we specifically request submission of 
information from sources in this source category regarding specific 
actions that would need to be undertaken to comply with the proposed 
amended requirements and the time needed to make the adjustments for 
compliance with any of the revised requirements. We note that 
information provided may result in changes to the proposed compliance 
dates.

V. Summary of Cost, Environmental, and Economic Impacts

A. What are the affected sources?

    Currently, ten major sources subject to the Surface Coating of 
Large Appliances NESHAP are operating in the United States. The 
affected source under the NESHAP is the collection of all coating 
operations; all storage containers and mixing vessels in which 
coatings, thinners, and cleaning materials are stored or mixed; all 
manual and automated equipment and containers used for conveying 
coatings, thinners, and cleaning materials; and all storage containers 
and all manual and automated equipment and containers used for 
conveying waste materials generated by a coating operation. A coating 
operation is defined as the equipment used to apply cleaning materials 
to a substrate to prepare it for coating application or to remove dried 
coating (surface preparation), to apply coating to a substrate (coating 
application) and to dry or cure the coating after application, or to 
clean coating operation equipment (equipment cleaning). A single 
coating operation may include any combination of these types of 
equipment, but always includes at least the point at which a coating or 
cleaning material is applied and all subsequent points in the affected 
source where organic HAP emissions from that coating or cleaning 
material occur. There may be multiple coating operations in an affected 
source.
    Currently, 43 major sources subject to the Printing, Coating, and 
Dyeing of Fabrics and Other Textiles NESHAP are operating in the United 
States. The affected source under the NESHAP includes the following 
three categories of operations: Web coating and printing operations, 
slashing operations, and dyeing and finishing operations.
    The web coating and printing operations subcategory is the 
collection of all web coating and printing equipment used to apply 
cleaning materials to a substrate on the coating or printing line to 
prepare it for coating or printing material application, to apply 
coating or printing materials to a substrate and to dry or cure the 
coating or printing materials, or equipment used to clean web coating/
printing operation equipment; all containers used for storage and 
vessels used for mixing coating, printing, thinning, or cleaning 
materials; all equipment and containers used for conveying coating, 
printing, thinning, or cleaning materials; all containers used for 
storage, and all equipment and containers used for conveying waste 
materials generated by a coating or printing operation; and all 
equipment, structures, and/or devices(s) used to convey, treat, or 
dispose of wastewater streams or residuals generated by a coating or 
printing operation.
    The slashing operations subcategory is the collection of all 
slashing equipment used to apply and dry the sizing on the warp yarn 
(the warp yarn are the vertical fibers, and a chemical compound 
referred to as sizing is used to bind and stiffen the yarn to provide 
abrasion resistance during weaving); all containers used for storage 
and vessels used for mixing slashing materials; all equipment and 
containers used for conveying slashing materials; all containers used 
for storage and all equipment and containers used for conveying waste 
materials generated by a slashing operation; and all equipment, 
structures, and/or devices(s) used to convey, treat, or dispose of 
wastewater streams or residuals generated by a slashing operation.
    The dyeing and finishing subcategory is the collection of all 
dyeing and finishing equipment used to apply dyeing or finishing 
materials, to fix dyeing materials to the substrate, to rinse the 
textile substrate, or to dry or cure the dyeing or finishing materials; 
all containers used for storage and vessels used for mixing dyeing or 
finishing materials; all equipment and containers used for conveying 
dyeing or finishing materials; all containers used for storage, and all 
equipment and containers used for conveying, waste materials generated 
by a dyeing or finishing operation; and all equipment, structures, and/
or devices(s) used to convey, treat, or dispose of wastewater streams 
or residuals generated by a dyeing or finishing operation.
    Currently, 16 major sources subject to the Surface Coating of Metal 
Furniture NESHAP are operating in the United States. The affected 
source under the NESHAP is the collection of all coating operations; 
all storage containers and mixing vessels in which coatings, thinners, 
and cleaning materials are stored or mixed; all manual and automated 
equipment and containers and all pumps and piping within the affected 
source used for conveying coatings, thinners, and cleaning materials; 
and all storage containers, all pumps and piping, and all manual and

[[Page 46311]]

automated equipment and containers within the affected source used for 
conveying waste materials generated by a coating operation. A coating 
operation is defined as the equipment used to apply cleaning materials 
to a substrate to prepare it for coating application or to remove dried 
or wet coating (surface preparation); to apply coating to a substrate 
(coating application) and to dry or cure the coating after application; 
and to clean coating operation equipment (equipment cleaning). A single 
coating operation may include any combination of these types of 
equipment, but always includes at least the point at which a coating or 
cleaning material is applied and all subsequent points in the affected 
source where organic HAP emissions from that coating or cleaning 
material occur. There may be multiple coating operations in an affected 
source.

B. What are the air quality impacts?

    At the current level of control, estimated emissions of volatile 
organic HAP from the Surface Coating of Large Appliances source 
category are approximately 120 tpy. Current estimated emissions of 
volatile organic HAP from the Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category are approximately 737 tpy. Current 
estimated emissions of volatile organic HAP from the Surface Coating of 
Metal Furniture source category are approximately 145 tpy.
    We do not estimate any volatile organic HAP emission reductions 
from the proposed requirement to use high-efficiency coating spray 
application equipment in the large appliance surface coating and the 
metal furniture surface coating source categories. We did not quantify 
these reductions; however, if a facility switched from spray guns with 
50-percent transfer efficiency to those with 65-percent transfer 
efficiency, the amount of coating reaching the part during spraying 
would increase by 30 percent, and the total amount of coating needed to 
complete the coating operation would be reduced by 23 percent, leading 
to a corresponding decrease in organic HAP emissions. Due to a 
combination of economic incentives and state rule requirements to use 
high-efficiency coating spray application equipment, we expect that 
facilities in this source category are already using high efficiency 
coating spray application equipment. However, we are specifically 
requesting information on any facilities not using high efficiency 
spray application equipment.
    All 69 major sources in the three source categories would be 
required to comply with the relevant emission standards at all times 
without the SSM exemption. We were unable to quantify the specific 
emissions reductions associated with eliminating the SSM exemption. 
However, eliminating the SSM exemption has the potential to reduce 
emissions by requiring facilities to meet the applicable standard 
during SSM periods.
    Indirect or secondary air emissions impacts are impacts that would 
result from the increased electricity usage associated with the 
operation of control devices (e.g., increased secondary emissions of 
criteria pollutants from power plants). Energy impacts consist of the 
electricity and steam needed to operate control devices and other 
equipment. The proposed amendments would 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 proposed amendments for 
reporting.
    Facilities in the large appliances and metal furniture source 
categories transitioning to high efficiency spray equipment may 
experience costs to purchase new equipment. We do not have sufficient 
information on current use of this type of equipment to develop a 
potential industry-wide cost. However, based the following example from 
a similar coating operation, we expect the change to result in a net 
cost savings. Due to the increased transfer efficiency from 45 percent 
with conventional spray guns to 65 percent with high volume low 
pressure spray guns, the amount of coating used per part is expected to 
decrease by approximately 31 percent. See the memorandum titled, 
Impacts of Prohibiting the Use of Conventional Spray Guns in the Wood 
Furniture Manufacturing Operations Source Category, October 19, 2010, 
EPA Docket Number EPA-HQ-OAR-2010-0786. For either type of gun, the 
annual costs are equal to the sum of the cost of the spray gun and the 
cost of coatings. The cost of coatings is equal to the product of the 
cost per volume of coating, the volume of coating used, and the number 
of days. The capital cost of a convention spray gun is approximately 
$200 and the cost of an air-assisted airless spray gun is approximately 
$700.00. Invalid source specified. The cost differential between a 
conventional spray gun and an air-assisted spray gun is $500.00, and, 
and a typical coating costs $15.00 per gallon. If a facility operates 
five days per week and 50 weeks per year, a typical year will contain 
250 days of operation. Complete cost recovery will occur when the air-
assisted-airless gun is used at a rate of 1.21 gallons of coatings per 
day for a year. If the coating cost is higher, the cost recovery will 
occur in less than one year. For more information on this cost 
analysis, see the memorandum titled Impacts of Prohibiting the Use of 
Conventional Spray Guns in the Wood Furniture Manufacturing Operations 
Source Category, (EPA Docket Number EPA-HQ-OAR-2010-0786).
    We are specifically soliciting comments on the current use of high 
efficiency spray equipment, the costs to transition from conventional 
spray application equipment to high efficiency spray application 
equipment (including costs for changes to coating delivery systems we 
may have overlooked), and the actual coating cost savings realized due 
to the change.
    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 V.III.C of this preamble.
    We estimate that for the large appliances and metal furniture 
source categories, should a source need to purchase and begin using 
high efficiency spray equipment, the cost savings associated with less 
coating material may offset the incremental equipment costs in typical 
cases.
    We are also soliciting comment on whether to require air emissions 
performance testing in each source category using the emission rate 
with add-on controls compliance option. We estimate that 15 facilities 
subject to the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles NESHAP would incur costs to conduct air emissions performance 
testing because they are currently using the emission rate with add-on 
controls compliance option. These 15 facilities have a total of 18 add-
on controls. This total does not include other facilities in this 
source category that have add-on controls and are already required to 
perform air emissions performance testing as a

[[Page 46312]]

condition of their state operating permit. The cost for a facility to 
conduct a destruction or removal efficiency air emissions performance 
test using EPA Method 25 or 25A is estimated to be about $19,000, and 
the total cost for all 15 facilities to test 18 add-on control devices 
in a single year would be $340,000. One facility subject to the Surface 
Coating of Large Appliances NESHAP is using the emission rate with add-
on controls compliance option and is already required to perform air 
emissions performance testing as a condition of their state operating 
permit, and would have no added costs if air emissions performance 
testing were required under the NESHAP. No facilities subject to the 
Surface Coating of Metal Furniture NESHAP are expected to incur costs 
to conduct air emissions performance testing because none are using 
add-on controls. 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 
Large Appliances Docket, Fabrics and Other Textiles Docket, and Metal 
Furniture Docket.

D. What are the economic impacts?

    The economic impact analysis is designed to inform decision-makers 
about the potential economic consequences of a regulatory action. For 
the current proposals, the EPA estimated the cost of becoming familiar 
with the rule and re-evaluating previously developed SSM record 
systems. For the proposed revisions to the NESHAP for the Surface 
Coating of Large Appliances, the total cost is estimated to be $23,000 
for the ten affected entities and is expected to range from 0.000002 to 
0.02 percent of annual sales revenue per affected entity. For the 
proposed revisions to the NESHAP for the Printing, Coating, and Dyeing 
of Fabrics and Other Textiles, the total cost is estimated to be 
$90,000 for the 43 affected entities and is expected to range from 
0.000005 to 0.42 percent of annual sales revenue per affected entity. 
For the proposed revisions to the NESHAP for the Surface Coating of 
Metal Furniture, the total cost is estimated to be $32,000 for the 16 
affected entities and is expected to range from 0.00007 to 0.02 percent 
of annual sales revenue per affected entity. For each of these sectors, 
the costs are not expected to result in a significant market impact, 
regardless of whether they are passed on to the purchaser or absorbed 
by the firms.
    The EPA also prepared a small business screening assessment to 
determine if any of the identified affected entities are small 
entities, as defined by the U.S. Small Business Administration. One of 
the facilities potentially affected by the proposed revisions to the 
NESHAP for the Surface Coating of Large Appliances is a small entity. 
The annualized costs associated with the proposed requirements for this 
facility is 0.02 percent of the annual sales revenue for that facility. 
Eighteen of the facilities potentially affected by the proposed 
revisions to the NESHAP for the Printing, Coating, and Dyeing of 
Fabrics and Other Textiles are small entities. The annualized costs 
associated with the proposed requirements for these 18 affected small 
entities range from 0.00067 to 0.25 percent of annual sales revenues 
per affected entity. Six of the facilities potentially affected by the 
proposed revisions to the NESHAP for the Surface Coating of Metal 
Furniture are small entities. The annualized costs associated with the 
proposed requirements for these six affected small entities range from 
0.001 to 0.02 percent of annual sales revenues per affected entity. For 
each of these sectors, there are no significant economic impacts on a 
substantial number of small entities from the proposed amendments. More 
information and details of this analysis is provided in the technical 
documents titled Economic Impact and Small Business Screening 
Assessments for Proposed Amendments to 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 Proposed Amendments to 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 Proposed Amendments to the 
National Emission Standards for Hazardous Air Pollutants for the 
Surface Coating of Metal Furniture (Subpart RRRR), available in the 
Large Appliances Docket, Fabrics and Other Textiles Docket, and Metal 
Furniture Docket, respectively.

E. What are the benefits?

    As stated above in section V.B. of this preamble, we were unable to 
quantify the specific emissions reductions associated with eliminating 
the SSM exemption. We also are unable to quantify potential emissions 
reductions of organic HAP. 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.

VI. Request for Comments

    We solicit comments on all aspects of this proposed action. In 
addition to general comments on this proposed action, we are also 
interested in additional data that may improve the risk assessments and 
other analyses. We are specifically interested in receiving any 
improvements to the data used in the site-specific emissions profiles 
used for risk modeling, including the data to estimate the acute 
multipliers. Such data should include supporting documentation in 
sufficient detail to allow characterization of the quality and 
representativeness of the data or information. Section VII of this 
preamble provides more information on submitting data.
    We are also specifically soliciting comment on the following:
     Our assumptions regarding hour-to-hour variation in 
emissions and our methods of calculating the multiplier for estimating 
the peak 1-hour emissions for each source category and any additional 
information that could help refine our approach.
     The current use of high efficiency spray equipment, the 
costs to transition from conventional spray application equipment to 
high efficiency spray application equipment (including costs for 
changes to coating delivery systems we may have overlooked), and the 
actual coating cost savings realized due to the change. We also request 
information on aspects of facility decision making concerning use of 
high efficiency coating methods, and facility specific operational, 
coating adherence, coating drying time, material compatibility, or 
other reasons that a facility may not have chosen to switch to high-
efficiency spray.
     The requirements for submitting electronic reports, 
including the draft templates developed for report submittal, and 
whether report frequency should be semiannual (as proposed) or annual 
for all three source categories. We specifically request comment on the 
format and usability of the template (e.g., filling out and uploading a 
provided spreadsheet versus entering the required information into an 
on-line fillable CEDRI web form), as well as the content, layout, and 
overall design of the template.
     The need to establish a standard during periods of 
malfunction for the Fabric and Other Textiles source category in this 
action, and we are seeking the specific information described in 
section IV.B.4 of this preamble to support the standard. We also 
request public comment and information pertaining to malfunction

[[Page 46313]]

periods for all sources in these source categories.
     The need for ongoing compliance demonstrations, in 
addition to one-time initial emissions and capture efficiency testing 
through air emissions testing when a source uses an add-on control to 
comply with the regulation.
     The proposed compliance periods, and we specifically 
request submission of information from sources in this source category 
regarding specific actions that would need to be undertaken to comply 
with the proposed amended requirements and the time needed to make the 
adjustments for compliance with any of the revised requirements.
     Whether the agency should ban the use of ethylene oxide in 
the Fabric and Other Textiles source category under the technology 
review.
     The relationship between section 112(d)(6), technology 
review, and 112(f), residual risk review. Specifically, we solicit 
comment on the extent to which findings that underlie a section 112(f) 
determination should be considered in making any determinations under 
section 112(d)(6).

C. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule have 
been submitted for approval to OMB under the PRA, as discussed for each 
source category covered by this proposal in sections VIII.C.1 through 
3.
1. Surface Coating of Large Appliances
    The Information Collection Request (ICR) document that the EPA 
prepared has been assigned EPA ICR number 1954.07. You can find a copy 
of the ICR in the Large Appliances Docket (Docket ID No. EPA-HQ-OAR-
2017-0670), and it is briefly summarized here.
    As part of the RTR for the Large Appliances NESHAP, the EPA is 
proposing to require that, for each coating operation for which 
coatings are spray applied, high efficiency spray equipment must be 
used, except when the facility is using the emission rate with add-on 
controls compliance option. In addition, the EPA is proposing revisions 
to the SSM provisions of the rule and proposing 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.
    Respondents/affected entities: Facilities performing surface 
coating of large appliances.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart NNNN).
    Estimated number of respondents: In the 3 years after the 
amendments are final, approximately 10 respondents per year would be 
subject to the NESHAP and no additional respondents are expected to 
become subject to the NESHAP during that period.
    Frequency of response: The total number of responses in year 1 is 
30. Years 2 and 3 would have no responses.
    Total estimated burden: The average annual burden to the large 
appliance facilities over the 3 years if the amendments are finalized 
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. There are no estimated capital and 
operation and maintenance (O&M) costs. 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 2071.07. You can find a copy of the ICR in the Fabrics and Other 
Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668), and it is briefly 
summarized here.
    The EPA is not proposing to revise the emission limitation 
requirements for this subpart. The EPA is proposing revisions to the 
SSM provisions of the rule, and proposing 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.
    Respondents/affected entities: Facilities performing printing, 
coating, and dyeing of fabrics and other textiles.

[[Page 46314]]

    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart OOOO).
    Estimated number of respondents: In the 3 years after the 
amendments are final, approximately 43 respondents per year will be 
subject to the NESHAP and no additional respondents are expected to 
become subject to the NESHAP during that period.
    Frequency of response: The total number of responses in year 1 is 
129. Years 2 and 3 would have no responses.
    Total estimated burden: The average annual burden to the fabrics 
and textiles coating facilities over the 3 years if the amendments are 
finalized is estimated to be 330 hours (per year). The average annual 
burden to the Agency over the 3 years after the amendments are final is 
estimated to be 32 hours (per year) for the Agency. Burden is defined 
at 5 CFR 1320.3(b).
    Total estimated cost: The average annual cost to the fabrics and 
textiles coating facilities is $30,000 in labor costs and no capital 
and O&M costs, in the first 3 years after the amendments are final. The 
average annual Agency cost over the first 3 years after the amendments 
are final is estimated to be $1,500.
3. Surface Coating of Metal Furniture
    The ICR document that the EPA prepared has been assigned EPA ICR 
number 1952.07. You can find a copy of the ICR in the Metal Furniture 
Docket (Docket ID No. EPA-HQ-OAR-2017-0669), and it is briefly 
summarized here.
    As part of the RTR for the Metal Furniture NESHAP, the EPA is 
proposing to require that, for each coating operation for which 
coatings are spray applied, high efficiency spray equipment must be 
used, except when the facility is using the emission rate with add-on 
controls compliance option. In addition, the EPA is proposing revisions 
to the SSM provisions of the rule and proposing the use of electronic 
data reporting for future performance test data submittals and semi-
annual reporting. This information would be collected to assure 
compliance with 40 CFR part 63, subpart RRRR.
    Respondents/affected entities: Facilities performing surface 
coating of metal furniture.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart RRRR).
    Estimated number of respondents: In the 3 years after the 
amendments are final, approximately 16 respondents per year will be 
subject to the NESHAP and no additional respondents are expected to 
become subject to the NESHAP during that period.
    Frequency of response: The total number of responses in year 1 is 
48. Years 2 and 3 would have no responses.
    Total estimated burden: The average annual burden to the large 
appliance facilities over the 3 years if the amendments are finalized 
is estimated to be 123 hours (per year). The average annual burden to 
the Agency over the 3 years after the amendments are final is estimated 
to be 25 hours (per year) for the Agency. Burden is defined at 5 CFR 
1320.3(b).
    Total estimated cost: The average annual cost to the metal 
furniture facilities is $11,000 in labor costs, in the first 3 years 
after the amendments are final. There are no estimated capital and O&M 
costs. 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.
    Submit your comments on the Agency's need for this information, the 
accuracy of the provided burden estimates and any suggested methods for 
minimizing respondent burden to the EPA using the dockets identified at 
the beginning of this rule. You may also send your ICR-related comments 
to OMB's Office of Information and Regulatory Affairs via email to 
[email protected], Attention: Desk Officer for the EPA. Since 
OMB is required to make a decision concerning the ICR between 30 and 60 
days after receipt, OMB must receive comments no later than October 12, 
2018. The EPA will respond to any ICR-related comments in the final 
rule.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. This 
action will not impose any requirements on small entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. The action imposes 
no enforceable duty on any state, local, or tribal governments or the 
private sector.

F. Executive Order 13132: Federalism

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

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

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

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

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe the environmental health or safety 
risks addressed by this action present a disproportionate risk to 
children. This action's health and risk assessments are contained in 
sections III.A and C, IV.A.1 and 2, IV.B.1 and 2, and IV.C.1 and 2 of 
this preamble and are further documented in the Large Appliances Risk 
Assessment Report, Fabrics and Other Textiles Risk Assessment Report, 
and Metal Furniture Risk Assessment Report in the Large Appliances 
Docket, Fabrics and Other Textiles Docket, and Metal Furniture Docket, 
respectively.

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

    This action is not a ``significant energy action'' because it is 
not likely to have a significant adverse effect on the supply, 
distribution, or use of energy. This action would not affect producers 
of energy (e.g., coal, oil, or natural gas producers), and would not 
affect electricity producers. This action would also not increase the 
energy demands of the facilities potentially affected by this action 
because it includes no proposed requirements that would be met through 
the use of additional energy consuming equipment.

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

    This rulemaking involves technical standards. The EPA is proposing 
to amend 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.
    We found three voluntary consensus standards (VCS) already allowed 
in the Surface Coating of Large Appliances NESHAP that have been 
replaced with newer versions of the methods. The first method, ASTM 
method Dl475-13, ``Standard Test Method for Density of Liquid Coatings, 
Inks, and Related Products,'' has replaced ASTM D1475-90, and it covers 
the measurement of density of paints, inks, varnishes, lacquers, and 
components thereof, other than pigments, when in fluid form; secondly, 
ASTM D2697-03 (2014) ``Standard Test Method for Volume Nonvolatile 
Matter in Clear or Pigmented Coatings'' has replaced ASTM D2697-86 
(1998), which is applicable to the determination of the volume of 
nonvolatile matter of a variety of coatings; and finally, ASTM D6093-97 
(2016) ``Standard Test Method for Percent Volume Nonvolatile Matter in 
Clear or Pigmented Coatings Using Helium Gas Pycnometer'' has replaced 
ASTM D6093-97(2003) which covers the determination of the percent 
volume nonvolatile matter of a variety of clear and pigmented coatings.
    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 proposes to 
incorporate by reference ASTM D2369-10 (2015), ``Test Method for 
Volatile Content of Coatings,'' which describes a procedure for the 
determination of the weight percent volatile content of solvent borne 
and waterborne coatings, as an acceptable alternative to EPA Test 
Method 24.
    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 is not proposing CARB Method 310, ``Determination of 
Volatile Organic Compounds in Consumer Products and Reactive Organic 
Compounds in Aerosol Coating Products,'' as an alternative to EPA 
Method 24 because the EPA has approved the method only for consumer 
products and aerosol coatings, which do not apply to the rulemakings or 
source categories addressed in this action.
    While the EPA has identified another 21 VCS each for Metal 
Furniture and Large Appliances, and two VCS for Fabrics Printing and 
Dyeing, as being potentially applicable to this proposed rule, we have 
decided not to use these VCS in this rulemaking. The use of these VCS 
would not be practical due to lack of equivalency, documentation, 
validation date, and other important technical and policy 
considerations. See the 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 
Large Appliances Docket (Docket ID No. EPA-HQ-OAR-2017-0670), Fabrics 
and Other Textiles Docket (Docket ID No. EPA-HQ-OAR-2017-0668), and 
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.
    The EPA welcomes comments on this aspect of the proposed rulemaking 
and, specifically, invites the public to identify potentially 
applicable VCS and to explain why such standards should be used in this 
regulation.

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

    The EPA believes that this action does not have disproportionately 
high and adverse human health or environmental effects on minority 
populations, low-income populations and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994).
    The documentation for this decision is contained in sections IV.A.1 
and 2, IV.B.1 and 2, and IV.C.1 and 2 of this preamble and the 
technical reports titled Risk and Technology Review--Analysis of 
Demographic Factors for Populations Living Near Surface Coating of 
Large Appliances 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 Printing, Coating, and 
Dyeing of Fabrics and Other Textiles Source Category Operations, 
September 2017, available in the Large Appliances Docket, Metal 
Furniture Docket, and Fabrics and Other Textiles Docket, respectively.
    As discussed in sections IV.A.1, IV.B.1, and IV.C.1 of this 
preamble, we performed a demographic analysis for each source category, 
which is an assessment of risks to individual demographic groups, of 
the population close to the facilities (within 50 km and within 5 km). 
In this analysis, we evaluated the distribution of HAP-related cancer 
risks and noncancer hazards from the Surface Coating of Large 
Appliances source category, Printing, Coating, and Dyeing of Fabrics 
and Other Textiles source category, and Surface Coating of Metal 
Furniture source category across different social, demographic, and 
economic groups within the populations living near operations 
identified as having the highest risks.
    The results of the Surface Coating of Large Appliances source 
category demographic analysis indicate that no one is exposed to a 
cancer risk at or above 1-in-1 million or to a chronic noncancer HI 
greater than 1. The proximity results (irrespective of risk) indicate 
that the population within 5 km of facilities in the Surface Coating of 
Large Appliances source category are greater than the corresponding 
national percentage for the following demographic percentages: 
``African American'' and ``Below the Poverty Level.''
    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 HS Diploma,'' and ``Below the Poverty Level.'' The proximity 
results (irrespective of risk) indicate that the population percentages 
for the below the poverty level demographic category within 5 km of 
facilities in the Printing, Coating, and Dying of Fabric and Other

[[Page 46316]]

Textiles source category are greater than the corresponding national 
percentage.
    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 HS Diploma,'' 
and ``Below the Poverty Level.'' The proximity results (irrespective of 
risk) indicate that the population within 5 km of facilities in the 
Surface Coating of Metal Furniture source category are greater than the 
corresponding national percentage for the following demographic 
percentages: ``African American,'' ``Hispanic or Latino,'' ``Over 25 
Without a HS Diploma,'' and ``Below the Poverty Level.''
    We do not expect this proposal to achieve significant reductions in 
HAP emissions. The EPA believes that this action does not have 
disproportionately high and adverse human health or environmental 
effects on minority populations, low-income populations, and/or 
indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, 
February 16, 1994) because it does not significantly affect the level 
of protection provided to human health or the environment. The 
documentation for this decision is contained in section IV 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

3. Section 63.4094 is added to read as follows:


Sec.  63.4094  What transfer efficiency requirement must I meet?

    (a) For any spray-applied coating operation(s) for which you use 
the compliant material option or the emission rate without add-on 
controls option, you are required to meet a transfer efficiency of 65 
percent or use the spray coating application method specified in 
paragraph (b) of this section. For any spray-applied coating 
operation(s) for which you use the emission rate with add-on controls 
option, the transfer efficiency requirement does not apply.
    (b) As an alternative to the transfer efficiency requirement in 
paragraph(a), for any spray-applied coating operation(s) for which you 
use you use the compliant material option or the emission rate without 
add-on controls option, you may apply all spray-applied coatings using 
high-volume, low-pressure (HVLP) spray equipment; electrostatic 
application; airless spray equipment; or air-assisted airless spray 
equipment, except as specified in paragraphs (b)(1) of this section. 
You must also meet the requirements in paragraph (b)(2) of this 
section.
    (1) You may apply spray-applied coatings using an alternative 
coating spray application method if you demonstrate that the 
alternative method achieves a transfer efficiency equivalent to or 
better than 65 percent, using procedures equivalent to the California 
South Coast Air Quality Management District's ``Spray Equipment 
Transfer Efficiency Test Procedure for Equipment User, May 24, 1989'' 
(for availability, see Sec.  63.14) and following guidelines equivalent 
to ``Guidelines for Demonstrating Equivalency with District Approved 
Transfer Efficient Spray Guns, September 26, 2002'' (for availability, 
see Sec.  63.14). For the purposes of this section, when using these 
equivalent guidelines or procedures, you are not required to submit an 
application with the test plan or protocol to the Administrator, 
conduct the test in the presence of an Administrator, or submit test 
results to the Administrator for review or approval. Instead you must 
comply with the recordkeeping requirement in Sec.  63.4130(l).
    (2) All spray application equipment must be operated according to 
company procedures, local specified operating

[[Page 46317]]

procedures, and/or the manufacturer's specifications, whichever is most 
stringent, at all times. If you modify spray application equipment, you 
must maintain emission reductions or a transfer efficiency equivalent 
to HVLP spray equipment, electrostatic application, airless spray 
equipment, or air-assisted airless spray equipment, and you must 
demonstrate equivalency according to paragraph (b)(1) of this section 
and comply with the recordkeeping requirement in Sec.  63.4130(l).

4. Section 63.4100 is amended by revising paragraph (b) and removing 
paragraph (d) to read as follows:


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

* * * * *
    (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. 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.

7. Section 63.4121 is added to read as follows:


Sec.  63.4121  What are my electronic reporting requirements?

    (a) 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). CEDRI 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

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 [date 2 years after date of publication of final 
rule in the Federal Register], 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 the CEDRI. 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 confidential 
business information (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 Road, 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 [date 2 years after date of publication of final 
rule in the Federal Register] or once the reporting template has been 
available on the CEDRI website for one year, whichever date is later, 
the owner or operator shall submit the semiannual compliance report 
required in Sec.  63.4120 to the EPA via the CEDRI. CEDRI can be 
accessed through the EPA's CDX (https://cdx.epa.gov). The owner or 
operator must use the appropriate electronic template on the CEDRI 
website for this subpart or an alternate electronic file format 
consistent with the XML schema listed on the CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The date report templates 
become available will be listed on the CEDRI website. If the reporting 
form for the semiannual compliance report specific to this subpart is 
not available in CEDRI at the time that the report is due, you must 
submit the report to the Administrator at the appropriate addresses 
listed in Sec.  63.13. Once the form has been available in CEDRI for 
one 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 confidential business information (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 Road, 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 
the CEDRI in the EPA's Central Data Exchange (CDX), and due to a 
planned or actual outage of either the EPA's CEDRI or CDX systems 
within the period of time beginning five 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

[[Page 46319]]

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

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


Sec.  63.4131  In what form and for how long must I keep my records?

    (a) Your records must be in a form suitable and readily available 
for expeditious review, according to Sec.  63.10(b)(1). Where 
appropriate, the records may be maintained as electronic spreadsheets 
or as a 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.

10. Section 63.4141 is amended by revising paragraphs (a)(1)(i), 
(a)(2), (a)(4), (b)(1), parameters ``mvolatiles'' and 
``Davg'' of Equation 1 in 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).
* * * * *
    (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 (2015), 
``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 Method D2697-03 (2014) or D6093-97. You may use ASTM 
Method D2697-03 (2014), ``Standard Test Method for Volume Nonvolatile 
Matter in Clear or Pigmented Coatings,'' or D6093-97, ``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 (2015) 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 Method D1475-13, ``Standard Test Method 
for Density of Liquid Coatings, Inks, and Related Products'' 
(incorporated by reference, see Sec.  63.14), ASTM D2111-10 (2015), 
``Standard Test Methods for Specific Gravity of Halogenated Organic 
Solvents and Their Admixtures'' (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 Method D1475-13 or ASTM D2111-10 (2015) 
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 Method D1475-13, ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products'' (incorporated by reference, see 
Sec.  63.14), ASTM D2111-10 (2015), ``Standard Test Methods for 
Specific Gravity of Halogenated Organic Solvents and Their Admixtures'' 
(incorporated by reference, see Sec.  63.14; if you use this method, 
the specific gravity must be corrected to a standard temperature), 
information from the supplier or manufacturer of the material, or 
reference sources providing density or specific gravity data for pure 
materials. If there is disagreement between test results from ASTM 
Method D1475-13 or ASTM D2111-10 (2015) and the supplier's or 
manufacturer's information, the test results will take precedence.

11. Section 63.4160 is amended by revising paragraphs (a)(1) and (b)(1) 
to read as follows:


Sec.  63.4160  By what date must I conduct performance tests and other 
initial compliance demonstrations?

    (a) * * *
    (1) All emission capture systems, add-on control devices, and CPMS 
you use to demonstrate compliance must be installed and operating no 
later than the applicable compliance date specified in Sec.  63.4083. 
Except for solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec.  63.4161(h), you must conduct a 
performance test of each capture system and add-on control device 
according to the procedures in Sec. Sec.  63.4164, 63.4165, and 
63.4166, and establish the operating limits required by Sec.  63.4092 
no later than the compliance date specified in Sec.  63.4083. For a 
solvent recovery system for which you conduct liquid-liquid material 
balances according to Sec.  63.4161(h), you must initiate the first 
material balance no later than the compliance date specified in Sec.  
63.4083.
* * * * *
    (b) * * *
    (1) All emission capture systems, add-on control devices, and CPMS 
you use to demonstrate compliance must be installed and operating no 
later than the applicable compliance date specified in Sec.  63.4083. 
Except for solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec.  63.4161(h), you must conduct a 
performance test of each capture system and add-on control device 
according to the procedures in Sec. Sec.  63.4164, 63.4165, and 
63.4166, and establish the operating limits required by Sec.  63.4092 
no later than 180 days after the applicable compliance date specified 
in Sec.  63.4083. For a solvent recovery system for which you conduct 
liquid-liquid material balances according to Sec.  63.4161(h), you must 
initiate the first material balance no later than 180 days after the 
applicable compliance date specified in Sec.  63.4083.

12. Section 63.4161 is amended by revising paragraph (g) introductory 
text and paragraph (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.
* * * * *
    (h) * * *
    (3) Determine the mass fraction of volatile organic matter for each 
coating used in the coating operation controlled by the solvent 
recovery system during the compliance period, kilogram, 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 (2015), ``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 (2015), or an 
approved alternative method, the test method results will govern.

13. Section 63.4163 is amended by revising paragraph (e) and removing 
and reserving paragraph (h) to read as follows:


Sec.  63.4163  How do I demonstrate continuous compliance with the 
emission limitations?

* * * * *
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec.  63.4093. If you did not develop a work 
practice plan, did not implement the plan, or did not keep the records 
required by Sec.  63.4130(k)(8), this is a deviation from the work 
practice standards that must be reported as specified in Sec. Sec.  
63.4110(b)(6) and 63.4120(g).

14. Section 63.4164 is amended by revising paragraph (a) introductory 
text and paragraph (a)(1) to read as follows:


Sec.  63.4164  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec.  
63.4160 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

[[Page 46321]]

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.

15. Section 63.4166 is amended by revising paragraph (b) introductory 
text to read as follows:


Sec.  63.4166  How do I determine the add-on control device emission 
destruction or removal efficiency?

* * * * *
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A in appendix A-7 of part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements. You may use Method 
18 in appendix A-6 of part 60 to subtract methane emissions from 
measured total gaseous organic mass emissions as carbon.

17. Section 63.4181 is amended by adding, in alphabetical order, 
definitions for ``Air-assisted airless spray'', ``Airless spray'', 
``Electrostatic spray'', ``High-volume, Low-pressure spray'' and 
revising the definition for ``Deviation'' to read as follows:


Sec.  63.4181  What definitions apply to this subpart?

* * * * *
    Air-assisted airless spray means any paint spray technology that 
spray uses compressed air to shape and distribute the fan of atomized 
paint, but still uses fluid pressure to create the atomized paint.
    Airless spray means any paint spray technology that relies solely 
on the fluid pressure of the paint to create an atomized paint spray 
pattern and does not apply any atomizing compressed air to the paint 
before it leaves the paint nozzle.
* * * * *
    Deviation means any instance in which an affected source subject to 
this subpart or an owner or operator of such a source:
    (1) 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
    (2) 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.

    (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. 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) You must submit the results of the performance test required in 
paragraph (b) of this section following the procedure specified in 
paragraphs (c)(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). (CEDRI 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 (c)(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 (c)(1) of this section.
    (d) Beginning on [date 2 years after date of publication of final 
rule in the Federal Register], 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 the CEDRI. (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 confidential 
business information (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 Road, 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.
    (e) Beginning on [date 2 years after date of publication of final 
rule in the Federal Register] or once the reporting template has been 
available on the CEDRI website for one year, whichever date is later, 
the owner or operator shall submit the semiannual compliance report 
required in paragraph (a) of this section to the EPA via the CEDRI. 
(CEDRI can be accessed through the EPA's CDX (https://cdx.epa.gov).). 
The owner or operator must use the appropriate electronic template on 
the CEDRI website for this subpart or an alternate electronic file 
format consistent with the XML schema listed on the CEDRI website 
(https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The date report templates 
become available will be listed on the CEDRI website. If the reporting 
form for the semiannual compliance report specific to this subpart is 
not available in CEDRI at the time that the report is due, you must 
submit the report to the Administrator at the appropriate addresses 
listed in Sec.  63.13. Once the form has been

[[Page 46327]]

available in CEDRI for one 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 confidential 
business information (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 Road, 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) If you are required to electronically submit a report through 
the Compliance and Emissions Data Reporting Interface (CEDRI) in the 
EPA's Central Data Exchange (CDX), and due to a planned or actual 
outage of either the EPA's CEDRI or CDX systems within the period of 
time beginning five 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.
    (g) 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 five 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.

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


Sec.  63.4312  What records must I keep?

* * * * *
    (i) 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 this recordkeeping requirement.
    (4) A record of actions taken to minimize emissions in accordance 
with Sec.  63.4300(b) and any corrective actions taken to return the 
affected unit to its normal or usual manner of operation.
    (j) If you use the emission rate with add-on controls option, the 
organic HAP overall control efficiency option, or the oxidizer outlet 
organic HAP concentration option, you must also keep the records 
specified in paragraphs (j)(1) through (8) of this section.

24. 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.

25. Section 63.4321 is amended by revising paragraphs (e)(1)(i)(A) and 
(e)(1)(iv) 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

[[Page 46328]]

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).
* * * * *
    (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.

26. Section 63.4341 is amended by revising paragraph (e)(4) 
introductory text and paragraph (f)(4) introductory text to read as 
follows:


Sec.  63.4341  How do I demonstrate initial compliance?

* * * * *
    (e) * * *
    (4) Calculate the organic HAP emission reduction for each 
controlled web coating/printing operation 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 this section. The equation applies the emission capture system 
efficiency and add-on control device efficiency to the mass of organic 
HAP contained in the coating, printing, thinning, and cleaning 
materials applied in the web coating/printing operation served by the 
emission capture system and add-on control device during the compliance 
period. For any period of time a deviation specified in Sec.  
63.4342(c) or (d) occurs in the controlled web coating/printing 
operation, then you must assume zero efficiency for the emission 
capture system and add-on control device. Equation 1 of this section 
treats the coating, printing, thinning, and cleaning materials applied 
during such a deviation as if they were used on an uncontrolled web 
coating/printing operation for the time period of the deviation.
* * * * *
    (f) * * *
    (4) Calculate the organic HAP emission reduction for each 
controlled dyeing/finishing operation not using liquid-liquid material 
balance. 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.

27. Section 63.4342 is amended by revising paragraph (f) and removing 
and reserving paragraph (h) to read as follows:


Sec.  63.4342  How do I demonstrate continuous compliance with the 
emission limitations?

* * * * *
    (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.

28. Section 63.4351 is amended by revising paragraph (d)(4) to read as 
follows:


Sec.  63.4351  How do I demonstrate initial compliance?

* * * * *
    (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.

30. Section 63.4360 is amended by revising paragraph (a) introductory 
text and paragraph (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. Sec.  
63.4340 or 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).

[[Page 46329]]

    (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.

31. Section 63.4362 is amended by revising paragraph (b) introductory 
text to read as follows:


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

* * * * *
    (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.

32. Section 63.4364 is amended by revising paragraphs (a)(6) through 
(8) to 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) 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 which generates data that 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).

33. Section 63.4371 is amended by adding, in alphabetical order, 
definitions for ``Air-assisted airless spray'', ``Airless spray'', 
``Electrostatic spray'', ``High-volume, Low-pressure spray'' and 
revising the definitions of ``Deviation'' and ``No organic HAP'' to 
read as follows:


Sec.  63.4371  What definitions apply to this subpart?

* * * * *
    Air-assisted airless spray means any paint spray technology that 
spray uses compressed air to shape and distribute the fan of atomized 
paint, but still uses fluid pressure to create the atomized paint.
    Airless spray means any paint spray technology that relies solely 
on the fluid pressure of the paint to create an atomized paint spray 
pattern and does not apply any atomizing compressed air to the paint 
before it leaves the paint nozzle.
* * * * *
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) 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
    (2) 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.
* * * * *
    Electrostatic spray is a method of applying a spray coating in 
which an electrical charge is applied to the coating and the substrate 
is grounded. The coating is attracted to the substrate by the 
electrostatic potential between them.
* * * * *
    High-volume, low-pressure spray means spray equipment that is used 
to apply coating by means of a spray gun that operates at 10.0 psig of 
atomizing air pressure or less at the air cap.
* * * * *
    No organic HAP means no organic HAP in Table 5 to this subpart is 
present at 0.1 percent by mass or more and no organic HAP not listed in 
Table 5 to this subpart is present at 1.0 percent by mass or more. The 
organic HAP content of a regulated material is determined according to 
Sec.  63.4321(e)(1).

36. Section 63.4894 is added to read as follows:


Sec.  63.4894  What transfer efficiency requirement must I meet?

    (a) For any spray-applied coating operation(s) for which you use 
the compliant material option or the emission rate without add-on 
controls option, you are required to meet a transfer efficiency of 65 
percent or use the spray coating application method specified in 
paragraph (b) of this section. For any spray-applied coating 
operation(s) for which you use the emission rate with add-on controls 
option, the transfer efficiency requirement does not apply.
    (b) As an alternative to the transfer efficiency requirement in 
paragraph (a) of this section, for any spray-applied coating 
operation(s) for which you use the compliant material option or the 
emission rate without add-on controls option, you may apply all spray-
applied coatings using high-volume, low-pressure (HVLP) spray 
equipment; electrostatic application; airless spray equipment; or air-
assisted airless spray equipment, except as specified in paragraphs 
(b)(1) of this section. You must also meet the requirements in 
paragraph (b)(2) of this section.
    (1) You may apply spray-applied coatings using an alternative 
coating spray application method if you demonstrate that the 
alternative method achieves a transfer efficiency equivalent to or 
better than 65 percent, using a procedure equivalent to the California 
South Coast Air Quality Management District's ``Spray Equipment 
Transfer Efficiency Test Procedure for Equipment User, May 24, 1989'' 
(incorporated by reference, see Sec.  63.14 of subpart A of this part) 
and following guidelines equivalent to ``Guidelines for Demonstrating 
Equivalency with District Approved Transfer Efficient Spray Guns, 
September 26, 2002'' (incorporated by reference, see Sec.  63.14 of 
subpart A of this part). For the purposes of this section, when using 
these equivalent guidelines or procedures, you are not required to 
submit an application with the test plan or protocol to the 
Administrator, conduct the test in the presence of an Administrator, or 
submit test results to the Administrator for review or approval. 
Instead you must comply with the recordkeeping requirement in Sec.  
63.4130(l).
    (2) 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. If you modify spray application equipment, you must maintain 
emission reductions or a transfer efficiency equivalent to HVLP spray 
equipment, electrostatic application, airless spray equipment, or air-
assisted airless spray equipment, and you must demonstrate equivalency 
according to paragraph (b)(1) of this section and comply with the 
recordkeeping requirement in Sec.  63.4130(l).

37. 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) 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) Reserved.

40. Section 63.4921 is added to read as follows:


Sec.  63.4921  What are my electronic reporting requirements?

    (a) You must submit the results of the performance test required 
Sec.  63.4920(b) 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 CEDRI. CEDRI 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 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 Road, 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 [date 2 years after date of publication of final 
rule in the Federal Register], 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.  63.4910(c) to the 
EPA via the CEDRI. 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 Confidential Business Information 
(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 Road, 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 [date 2 years after date of publication of final 
rule in the Federal Register] or once the reporting template has been 
available on the CEDRI website for one year, whichever date is later, 
the owner or operator shall submit the semiannual compliance report 
required in Sec.  63.4920 to the EPA via the CEDRI. CEDRI can be 
accessed through the EPA's CDX (https://cdx.epa.gov). The owner or 
operator must use the appropriate electronic template on the CEDRI 
website for this subpart or an alternate electronic file format 
consistent with the XML schema listed on the CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri). The date report templates 
become available will be listed on the CEDRI website. If the reporting 
form for the semiannual compliance report specific to this subpart is 
not available in CEDRI at the time that the report is due, you must 
submit the report to the Administrator at the appropriate addresses 
listed in Sec.  63.13. Once the form has been available in CEDRI for 
one 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 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 Road, 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 
the CEDRI in the EPA's Central Data Exchange (CDX), and due to a 
planned or actual outage of either the EPA's CEDRI or CDX systems 
within the period of time beginning five business

[[Page 46336]]

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 five 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.

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


Sec.  63.4930  What records must I keep?

* * * * *
    (j) For each deviation from an emission limitation reported under 
Sec.  63.4920(a)(5), (a)(6), and (a)(7), a record of the information 
specified in paragraphs (j)(1) through (4) of this section, as 
applicable.
    (1) The date, time, and duration of each deviation, as reported 
under Sec.  63.4920(a)(5), (a)(6), and (a)(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), (a)(6), and (a)(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

42. Section 63.4931 is amended by revising paragraph (a) introductory 
text 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.

43. Section 63.4941 is amended by revising paragraphs (a)(1)(i), (a)(2) 
and (4), (b)(1), parameters ``mvolatiles'' and 
``Davg'' of Equation 1 of paragraph (b)(3), and paragraph 
(c) 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 (2015), 
``Test Method for Volatile Content of Coatings'' (incorporated by 
reference, see Sec.  63.14).
* * * * *
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, 
such as manufacturer's formulation data, if it represents each organic 
HAP in Table 5 to this subpart that is present at 0.1 percent by mass 
or more and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not listed in Table 5 to this

``Standard Test Method for Volume Nonvolatile Matter in Clear or 
Pigmented Coatings'' (incorporated by reference, see Sec.  63.14), or 
D6093-97, ``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. Alternatively, you may use another test 
method once you obtain approval from the Administrator according to the

    (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:

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 (2015), or an approved alternative method, the test method 
results will govern.

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.
