National Emission Standards for Hazardous Air Pollutants: Surface 
Coating of Large Appliances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This action promulgates national emission standards for 
hazardous air pollutants (NESHAP) for existing and new facilities that 
apply surface coatings to large appliances. These final standards 
implement section 112(d) of the Clean Air Act (CAA) which requires the 
Administrator to regulate emissions of hazardous air pollutants (HAP) 
listed in section 112(b) of the CAA. The intent of the standards is to 
protect the public by requiring new and existing major sources to 
control emissions to the level attainable by implementing the maximum 
achievable control technology (MACT).
    Sources typically emit the following HAP: glycol ethers, methylene 
diphenyl diisocyanate, methyl ethyl ketone, toluene, and xylene. These 
compounds account for over 80 percent of the nationwide HAP emissions 
from this source category. These pollutants can cause reversible or 
irreversible toxic effects to people following exposure.

EFFECTIVE DATE: This rule is effective July 23, 2002. The incorporation 
by reference of certain publications listed in today's final rule is 
approved by the Director of the Federal Register as of July 23, 2002.

SUPPLEMENTARY INFORMATION:
    Docket. The docket is an organized and complete file of all the 
information considered by EPA in the development of rulemaking. The 
docket is a dynamic file because material is added throughout the 
rulemaking process. The docketing system is intended to allow members 
of the public and industries involved to readily identify and locate 
documents so that they can effectively participate in the rulemaking 
process. The contents of the docket, including the BID for the proposed 
and promulgated standards and the EPA responses to significant comments 
will serve as the record in case of judicial review. (See section 
307(d)(7)(A) of the CAA.) The regulatory text and other materials 
related to today's final rule are available for review in the docket, 
or copies may be mailed on request from the Air and Radiation Docket 
and Information Center by calling (202) 260-7548. A reasonable fee may 
be charged for copying docket materials. Worldwide Web (WWW). In 
addition to being available in the docket, an electronic copy of 
today's final rule will also be available on the WWW through the 
Technology Transfer Network (TTN). Following signature by the EPA 
Administrator, a copy of the final rule will be posted on the TTN's 
policy and guidance page for newly proposed or promulgated rules at 
http://www.epa.gov/ttn/oarpg. The TTN provides information and 
technology exchange in various areas of air pollution control. If more 
information regarding the TTN is needed, call the TTN HELP line at 
(919) 541-5384.
    Regulated Entities. If your facility applies surface coatings to 
large appliance parts or products, you may be a regulated entity. 
Categories and entities potentially regulated by the final standards 
are shown in the following table. This table is slightly different from 
the table contained in the proposal preamble at 65 FR 81135. The 
changes made to the table between proposal and promulgation are the 
result of public comments. These changes clarify the types of 
facilities that will be affected by the promulgated standards.

    As in the proposal, major sources classified under other NAICS 
codes will be subject to the standards if they perform large appliance 
surface coating operations and meet the other applicability criteria. 
Conversely, some facilities listed under these codes may not be 
affected because some of the codes in the table cover products that are 
not defined as large appliances for the purposes of the rule.
    This table is not intended to be exhaustive, but rather provides a 
guide for entities likely to be regulated by this action. To determine 
whether your facility is subject to the rule, you should carefully 
examine the applicability criteria in Sec. 63.4081 of the rule. If you 
have questions regarding how this action applies to a particular 
entity, consult the appropriate EPA Regional Office representative.
    Judicial Review. The NESHAP for large appliance surface coating 
operations was proposed on December 22, 2000 (65 FR 81134). Under 
section 307(b)(1) of the CAA, judicial review of NESHAP is available 
only by the filing of a petition for review in the U.S. Court of 
Appeals for the District of Columbia Circuit by September 23, 2002. 
Only those objections to the rule which were raised with reasonable 
specificity during the period for public comment may be raised during 
judicial review. Under section 307(b)(2) of the CAA, the requirements 
that are the subject of today's final rule may not be challenged later 
in civil or criminal proceedings brought by EPA to enforce the 
requirements.

I. Background

A. What Is the Source of Authority for Development of NESHAP?

    Section 112 of the CAA requires us to list categories and 
subcategories of major sources and area sources of HAP and to establish 
NESHAP for the listed source categories and subcategories. The category 
of major sources covered by the final NESHAP was listed on July 16, 
1992 (57 FR 31576) under the Surface Coating Processes industry group. 
Major sources of HAP are those that have the potential to emit 
considering controls, in the aggregate, 10 tons per year (tpy) or more 
of any HAP or 25 tpy or more of any combination of HAP.

B. What Criteria Do We Use in the Development of NESHAP?

    Section 112 of the CAA requires that we establish NESHAP for the 
control of HAP from both existing and new major sources. The CAA 
requires the NESHAP to reflect the maximum degree of reduction in 
emissions of HAP that is achievable. This level of control is commonly 
referred to as the MACT.
    The MACT floor is the minimum control level allowed for NESHAP and 
is defined under section 112(d)(3) of the CAA. In essence, the MACT 
floor ensures that the standard is set at a level that assures that all 
major sources achieve the level of control at least as stringent as 
that already achieved by the better-controlled and lower-emitting 
sources in each source category or subcategory. For new sources, the 
MACT floor cannot be less stringent than the emission control that is 
achieved in practice by the best-controlled similar source. The MACT 
standards for existing sources can be less stringent than the standards 
for new sources, but they cannot be less stringent than the average 
emission limitation achieved by the best-performing 12 percent of 
existing sources in the category or subcategory (or the best performing 
five sources for categories or subcategories with fewer than 30 
sources).
    In developing MACT, we also consider control options that are more 
stringent than the floor. We may establish standards more stringent 
than the floor based on consideration of the cost of achieving the 
emission reductions, any health and environmental impacts, and energy 
requirements.

II. What Changes and Clarifications Have We Made to the Proposed 
Standards?

    In response to public comments received on the proposed standards, 
we made several changes in developing the final rule. While some of the 
changes were designed to make our intentions clearer, other changes had 
a direct effect on the degree of coverage of the standards. The 
substantive comments and our responses and rule changes are summarized 
in the following sections. A more detailed summary can be found in the 
BID for the final rule which is available from several sources (see 
ADDRESSES).

A. Scope of Source Category

    In the proposal, we defined the regulated community for the 
standards to be facilities that apply surface coatings to large 
appliances or components of large appliances. In the proposal BID and 
the table of regulated entities in the proposal preamble (65 FR 81135, 
December 22, 2000), we stated that the facilities are generally 
included under the following NAICS codes (and their SIC code 
equivalents): 335221 (3631) household cooking appliances, 335222 (3632) 
household refrigerator and home freezer, 335224 (3633) householdlaundry 
equipment manufacturing, 335228 (3639) other major household 
appliances, 333415 (3585) air-conditioning and warm air heating 
equipment and commercial and industrial refrigeration equipment, and 
333319 (3589) service appliance. We cautioned that some facilities and 
products with these codes do not fit under the large appliance 
category, and similarly, there may be facilities under other codes that 
do in fact coat large appliances. Thus, these industrial codes were 
given as a guide but were not intended to be used as the only basis for 
determining applicability of the rule.
    The codes listed above are associated with household cooking 
equipment, refrigerators/freezers, laundry equipment, and floor vacuums 
and polishers, and various types of

[[Page 48256]]

commercial and industrial heating, ventilation, and refrigeration 
equipment. Table 2-1 in the proposal BID listed examples of large 
appliances that are produced by facilities in these categories.
    Several commenters stated that the scope of the category as 
proposed was overly broad and confusing. They felt that we had included 
several products not normally considered to be large appliances, and 
that these products should be regulated under the miscellaneous metal 
parts and products NESHAP currently under development. As an 
alternative, if EPA decided not to change the mix of products defined 
to be large appliances, one commenter suggested that we change the name 
of the source category to better match the product mix being 
represented.
    In addition, commenters asked for clarification on the 
applicability of the rule to certain coatings such as porcelain enamel, 
powder coatings, and asphalt interior soundproofing. The final rule 
clarifies that the aforementioned coatings are considered coatings for 
the purposes of the rule and will be subject to subpart NNNN. We also 
clarified that phosphating (a form of pretreatment) and metal plating 
are excluded as coatings in subpart NNNN.
    Our proposed definition of the large appliances source category was 
formed using the six SIC/NAICS codes as a foundation, and then 
including the products under those codes that we believed should be 
included as large appliances. Some commenters expressed confusion when 
comparing the preamble table to BID Table 2-1. We have clarified the 
scope of the source category by including definitions for large 
appliance product and large appliance part in the final rule. The 
definitions list the parts and products intended to be regulated under 
the final rule, and they supercede the listing in Table 2-1 of the 
proposal BID. We also modified the proposal preamble table and are 
including it in the BID for the final rule. We have added Commercial 
Laundry Equipment and have deleted Floor Waxing/Polishing and Motor 
Vehicle Air-Conditioning, in keeping with our intent at proposal. In 
addition, we have also deleted heat transfer coils and large commercial 
and industrial chillers from the table and from coverage by the large 
appliances NESHAP.
    A few commenters stated that the heat transfer coils used to cool 
fluids in refrigeration and air-conditioning systems typically have 
unique coating formulation requirements, and suitable coatings are not 
available in a low-HAP formulation. The need for special coatings 
arises from the complex geometry of heat transfer coils, as well as 
exposure requirements in food processing and other special 
environments. The coating information we collected and used to 
determine the MACT floor did not contain coatings used specifically for 
heat transfer coils. The commenters asked that this large appliance 
component be removed from the large appliances category and regulated 
under the miscellaneous metal parts and products NESHAP.
    We have examined the submitted data and arguments and have 
concluded that the data analyzed since proposal offer sufficient 
justification to revise the scope of the source category. Therefore, we 
have excluded heat transfer coils from coverage under the large 
appliances NESHAP.
    A trade organization and one manufacturer of large commercial and 
industrial chillers (equipment that produces chilled water for use in a 
number of industrial processes including heating, ventilating, and air 
conditioning (HVAC) applications) commented that large chillers are 
very different from other products included as large appliances. They 
said that large HVAC products are produced in much lower volumes than 
white goods and are often custom designed. Furthermore, they are often 
subjected to outdoor environments requiring that they meet strict 
performance criteria, and they have a longer expected life. Commercial 
and industrial chillers are much larger than most other large 
appliances and are painted after assembly. Therefore, they cannot be 
put through a baking oven to cure the coatings, which restricts the 
coatings available for use.
    We requested additional supporting data on large chiller equipment 
coating operations and the available coatings. We also visited one of 
the few facilities that manufactures that equipment. Our evaluation of 
the chiller coating operations led us to determine that large 
commercial and industrial chillers should be excluded from the Large 
Appliances category for the reasons described by the commenter.

B. Definitions

    We have added definitions for large appliance product and large 
appliance part to the final rule. These definitions include ``white 
goods'' appliances, as well as certain HVAC equipment used in 
commercial and industrial applications. However, specifically excluded 
from the definition of large appliance product are heat transfer coils, 
large commercial and industrial chillers, and motor vehicle air-
conditioning units.
    We added several other new definitions in response to comments and 
to increase the clarity of the rule. Newly defined terms include 
adhesive, facility maintenance, heat transfer coil, large commercial 
and industrial chillers, and month. Clarifying changes were also made 
to the proposed definitions for coating operation, manufacturer's 
formulation data, and surface preparation.

C. Overlap With Other NESHAP Categories

    Several commenters requested that the final rule provide compliance 
flexibility for facilities that coat a variety of items in addition to 
large appliances or large appliance components. Such facilities may be 
affected by several coating NESHAP, such as the standards for large 
appliances, miscellaneous metal parts and products, and plastic parts 
and products. They sought a regulatory approach that would allow 
facilities to opt specific coating operations or product lines, that 
are collateral to large appliance coating operations, out of the rule 
and into either the miscellaneous metal parts and products rule under 
development or the plastic parts and products rule that is also under 
development. Commenters also believed that plants coating types of 
items with a wider use beyond large appliances (such as motors, 
handles, hinges, etc.) should have the choice of those operations being 
covered by either the miscellaneous metal or plastic parts rule, even 
if the specific items are designed to be used on large appliances.
    We understand that many facilities may find it beneficial to 
consolidate their regulatory coverage for a number of different types 
of coating operations (such as large appliances, miscellaneous metal 
parts, and plastic parts) into a single NESHAP. Consolidation may 
reduce the amount of records, reports, or compliance calculations that 
the facility would have to maintain. To address the issue of multiple 
regulatory coverage, we are including a new provision in the final rule 
that allows the consolidation sought by the commenters. Under this 
approach, as an alternative to complying separately with multiple 
coating NESHAP, a facility may choose to be subject to the requirements 
of only one applicable NESHAP, provided it is the most stringent of the 
applicable subparts. The test for stringency is a demonstration that 
the facilitywide HAP emissions from all surface coating operations will 
be less than or equal to the emissions achieved by complying separately 
with

[[Page 48257]]

all applicable subparts of 40 CFR part 63.
    There are many facilities that apply surface coatings to a variety 
of items that may be used on large appliances, but which also have 
application to other types of products. We agree that such multi-
purpose items are not exclusively large appliance parts and may be 
considered more appropriately miscellaneous metal parts or plastic 
parts. Therefore, we are excluding these items from coverage under the 
final rule. However, if a large appliance source prefers to have all 
its coating operations subject to only one coating NESHAP to 
consolidate recordkeeping and reporting requirements, the source would 
have the option described above of complying with only the most 
stringent applicable NESHAP.

D. Other Changes and Clarifications

    A number of commenters found the proposed compliance options 
confusing and some suggested variations on the way these options should 
be applied.
    One of the commenters believed that the calculations, monthly 
compliance determinations, and recordkeeping required under the 
compliant material option should not apply to coating operations that 
use only powder coatings that contain no HAP. The commenter suggested 
relevant portions of the proposed requirements that he believed should 
not be applicable to these powder coating operations.
    We have reviewed the proposed calculations, compliance 
determinations, and recordkeeping requirements for the compliant 
material option and believe the commenter identified a need to clarify 
the rule language. The proposed language would have required an 
affected source choosing the compliant material option and using only 
powder coatings and non-HAP cleaning materials to determine the mass 
fraction of organic HAP, the volume fraction of solids, and the density 
for each coating, and then to determine the ratio of organic HAP to 
coating solids. Records and certain reports would have had to include 
such calculations. We did not intend to require this unnecessary 
calculation for non-HAP coatings at proposal. Clearly, if a coating 
contains no organic HAP, it is not useful to record and report such 
calculations since the result is obviously zero kilogram (kg) organic 
HAP per liter of coating solids. Therefore, we have added a provision 
in Sec. 63.4141(a) and (d) of the final rule specifying that if the 
mass fraction of organic HAP in a coating is zero, as determined 
according to Sec. 63.4141(a) (through test results or manufacturer's 
formulation data), then the source is not required to determine the 
volume fraction of coating solids and density or to calculate the 
organic HAP content. This new provision applies to all types of 
coatings that contain no organic HAP, not just powder coatings. For 
such a coating, Sec. 63.4141(d) of the final rule specifies that the 
organic HAP content equals zero and no calculation is required. The 
following notification, reporting, and recordkeeping sections of the 
rule were also revised to fully incorporate this provision: 
Secs. 63.4110(b)(8) and (b)(8)(i), 63.4120(d)(2), and 63.4130(c), 
(c)(1), (f), and (g). We believe that these changes are responsive to 
the commenter's concerns, and that they retain only the requirements 
that are essential for compliance and enforcement purposes.
    Some commenters asked whether different compliance options could be 
combined for the same coating operation in order for sources to gain 
more flexibility in the way coatings and other materials are used in an 
operation. We proposed three compliance options: Option 1 when using 
compliant materials, Option 2 when determining emission rate without 
add-on controls, and Option 3 when using emission controls. The three 
proposed compliance options address different situations and were 
intended to be applied on a one-at-a-time basis (see Sec. 63.4091 
introductory language). Both Options 1 and 2 cannot logically be used 
on one coating operation at the same time. If all coatings meet the 
limit and all thinners and cleaners are HAP-free, then Option 1 could 
be used and, thus, there would be no need to combine data elements for 
multiple coatings, thinners, and cleaning materials to derive an 
emission rate (required for Option 2). If the coatings, thinners, and 
cleaning materials do not meet the Option 1 criteria, or if the source 
owner or operator chooses not to use Option 1, then Option 2 must be 
used (or Option 3 if an add-on control device is in use). In no case 
may coatings, thinners, and cleaning materials accounted for under one 
option be included in the accounting under another option. Because the 
compliance options are designed to accommodate different situations 
and, due to the lack of compelling information or justification for the 
commenter's suggested rule change, the final compliance option 
provisions are the same as proposed.
    Additionally, one commenter believed that a clarification was 
needed for proposed Sec. 63.4081(a)(3), which excluded certain 
categories of surface coating from coverage by the rule, such as 
facility maintenance operations. The commenter wanted the rule to make 
specific mention of the paint booths that are used for maintaining 
manufacturing equipment. We agree with the commenter that the rule 
should not apply to paint booths or to other surface coating equipment 
used exclusively to coat something other than large appliances. If, 
however, the paint booth or equipment is sometimes used for large 
appliance surface coating, it would be subject to the standards during 
those times and would need to be considered part of the affected 
source. It also is subject to the standards if it is used for cleaning 
of equipment used in coating operations, e.g., application equipment, 
hangers, and racks (see Sec. 63.4081(c)(6) and the definition of 
coating operation in Sec. 63.4181). To clarify our intent, we have 
included the following definition of facility maintenance in the final 
rule: Facility maintenance means the routine repair or refurbishing 
(including surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of a facility or that are 
necessary for the facility to function in its intended capacity. It 
does not mean cleaning of equipment that is part of a large appliances 
coating operation.
    One commenter suggested that EPA establish a low-use exemption 
threshold for military installations where military members could apply 
coatings at on-base hobby shops and housing areas to repair personally 
owned appliances. Generally, in hobby shops, the prevailing coating 
application would involve hand-held, non-refillable aerosol containers. 
However, individuals using hobby shop facilities may also apply the 
coatings by methods other than hand-held aerosol cans. In the proposal, 
we excluded hand-held aerosol container coatings from the rule but did 
not exclude other coating application methods, specifically those 
related to hobby shops. However, in considering this comment, we 
concluded that coating application by individuals who repair, 
refurbish, or recoat large appliances or other types of products at 
military hobby shops or base housing areas does not compare to the 
coating operations conducted at facilities that apply coatings as a 
step in the production of large appliances. Therefore, these coating 
activities are not subject to the standards. We believe that expanding 
the exclusion in Sec. 63.4081(d)(4) to include hobby shops is a more 
appropriate way to address this issue than creating a low-use exemption 
that would necessitate coating usage recordkeeping at the hobby shop. 
Therefore, Sec. 63.4081(d)(4) of the final rule excludes research or

[[Page 48258]]

laboratory facilities; janitorial, building, and facility maintenance 
operations; hobby shops operated for non-commercial purposes; and the 
use of hand-held, non-refillable aerosol containers.
    In addition to the changes described above, we noted several areas 
of the proposed rule that warrant revision even though commenters did 
not object to them. The changes are necessary so that the provisions 
properly reflect our intent and are consistent with other surface 
coating NESHAP under development. As proposed, Sec. 63.4100(a)(2) 
indicated that affected sources using the emission rate with add-on 
controls options would not have to comply with the standards during 
periods of startup, shutdown, and malfunction. This provision is often 
found in NESHAP in which compliance with the standards is based solely 
on the results of a short-term initial performance test and short-term 
averaging of continuous monitoring results thereafter. After proposal 
of the large applicances NESHAP, we realized that this provision is not 
appropriate for the surface coating NESHAP when these short-term test 
and monitoring results are only one component of a compliance 
determination that determines emissions over a long period of time, 
which in this case is a month. For the large appliances NESHAP, the 
source owner or operator will use the performance test and continuous 
monitoring results in combination with data on coatings and other 
materials used over a month's period of time. These components will be 
combined to calculate a monthly organic HAP emission rate. Since there 
may be many startups and shutdowns of a coating operation over the 
course of a month as part of normal operation, it is not appropriate to 
exempt such periods from compliance with the standards. The rule does 
require in Sec. 63.4100(d) that you develop and operate according to a 
startup, shutdown, and malfunction plan, and Sec. 63.6163(h) provides 
the following: ``Consistent with Secs. 63.6(e) and 63.7(e)(1), 
deviations that occur during a period of startup, shutdown, or 
malfunction of the emission capture system, add-on control device, or 
coating operation that may affect emission capture or control device 
efficiency are not violations if you demonstrate to the Administrator's 
satisfaction that you were operating in accordance with the startup, 
shutdown, and malfunction plan. The Administrator will determine 
whether deviations that occur during a period of startup, shutdown, or 
malfunction are violations according to the provisions in 
Sec. 63.6(e).'' We believe that this provision along with a month-long 
compliance period that will accommodate potential short-term higher 
emission rates that might occur due to startup, shutdown, or 
malfunction are adequate and that the proposed exemption is not 
necessary or appropriate. Therefore, it is not included in the final 
standards.
    Another change we made to the rule is intended to simplify the 
compliance provisions for the emission rate with add-on controls 
option. We removed Sec. 63.4162, which was proposed to provide explicit 
instructions for determining compliance with the emission rate with 
add-on controls option when the coating operation is operated under 
several different operating conditions. We found after proposal, 
however, that this section as proposed added unnecessary complexity to 
the standards, and that the compliance provisions are adequate without 
it. Therefore, we removed it from the final standards.
    To provide consistency with other surface coating NESHAP, we added 
provisions in Sec. 63.4167(b)(3) and (4) to allow sources an 
alternative to the proposed operating limits for catalytic oxidizers 
that require monitoring of inlet and outlet temperature before and 
after the catalyst bed and the temperature difference across the bed. 
This alternative allows you to monitor only the temperature before the 
catalyst bed if you develop and follow an onsite inspection and 
maintenance plan for the catalytic oxidizer. For some sources, this 
would be a preferable alternative. Another addition we made to provide 
consistency is a description of continuous monitoring requirements for 
concentrators in Sec. 63.4167(e) and (f) and in Table 1 to the subpart. 
As proposed, a source using a concentrator would have had to seek and 
obtain approval from the permitting authority for the continuous 
monitoring it wanted to use to comply with the operating limits since 
we did not include such monitoring provisions in the proposed 
standards. Because we have included these provisions in the final 
standards, a source can comply with them and, therefore, avoid having 
to apply for and obtain specific approval unless it wishes to monitor 
something different than what is specified in the new provisions. The 
concentrator monitoring requirements are the same as those in other 
surface coating NESHAP under development.
    In addition to the revisions described above, we have made 
clarifying editorial changes throughout the rule to ensure it 
accurately expresses our intent and to promote consistency with other 
surface coating NESHAP currently under development. These changes do 
not affect the stringency of the requirements since they are only 
clarifications of the proposed provisions.

III. What Are the Final Standards?

A. What Is the Source Category?

    The large appliances source category includes facilities that apply 
coatings to large appliance parts or products. The rule applies to 
facilities that are a major source, are located at a major source, or 
are part of a major source of HAP emissions. Large appliances include 
``white goods'' such as ovens, refrigerators, freezers, dishwashers, 
laundry equipment, trash compactors, water heaters, comfort furnaces, 
and electric heat pumps. Large appliances also include most HVAC 
equipment intended for any application. However, not included in the 
source category are motor vehicle air-conditioning units, heat transfer 
coils, and large commercial and industrial chillers. Other coating 
operations not included in the source category are: the coating of 
large appliance parts that have a wider use beyond large appliances 
(such as handles or fasteners), repair or maintenance painting of large 
appliance parts or products used by a facility, the surface coating of 
heat transfer coils or large commercial and industrial chillers, 
research or laboratory facilities and facility maintenance operations, 
and hobby shops operated for non-commercial purposes.

B. What Is the Affected Source?

    The affected source includes all of the activities that involve 
coatings, thinners, and cleaning materials used in large appliance 
coating operations. These activities include: (1) Surface preparation 
of the large appliance parts or products; (2) preparation of coatings 
for application; (3) applying the coatings; (4) flash-off, drying, or 
curing of the coatings; (5) cleaning of coating equipment; (6) storage 
of coatings, thinners, and cleaning materials; (7) conveying of these 
materials; and (8) handling and conveying of waste materials generated 
by the coating operations.

C. What Are the Emission Limits?

    The emission limits are different for existing and new sources and 
have not changed since proposal. For an existing source, you must limit 
organic HAP emissions to no more than 0.13 kg/liter (1.1 pound (lb)/
gallon (gal)) of coating solids used during each compliance

[[Page 48259]]

(monthly) period. For a new or reconstructed source, you must limit 
emissions to no more than 0.022 kg/liter (0.18 lb/gal) of coating 
solids. These limits apply to the total of all coatings, thinners, and 
cleaning materials used in coating operations at the affected source.
    There are three compliance options available for meeting the 
emission limits. The compliant material option requires that each 
coating used in the operation meet the limit, and each thinner and 
cleaning material must contain no organic HAP. Under the emission rate 
without add-on controls option, you may average all of the coatings, 
thinners, and cleaning materials together and demonstrate that the 
overall emission rate is in compliance with the applicable limit. The 
emission rate with add-on controls option applies to coating operations 
for which add-on controls are used to meet the limit. Under this 
option, you must meet certain operating limits for the capture systems 
and control devices and follow a work practice plan for your material 
storage, mixing, conveying, and spills.

D. What Are the Testing and Initial and Continuous Compliance 
Requirements?

    Existing sources will have to be in compliance no later than July 
25, 2005. New and reconstructed sources will have to be in compliance 
by this same date or upon startup, whichever is later. The initial 
compliance period begins on the compliance date and ends on the last 
day of the first full month following this date, except that for new or 
reconstructed sources required to conduct performance tests the initial 
compliance period ends on the last day of the first full month 
following the test. Note that ``month'' means a calendar month or a 
similar pre-specified period in order to accommodate facility 
accounting periods. The performance test may be conducted up to 180 
days after the compliance date.
    As discussed earlier, the owner or operator must select one of 
three compliance options for each coating operation, but may change the 
approach used for any operation at any time. For the compliant material 
and emission rate without add-on controls option, you will determine 
the mass of organic HAP in coatings, thinners, and cleaning materials 
and the volume fraction of coating solids either from manufacturer's 
formulation data or from test results using the methods in the final 
rule. Alternative test methods may be used with EPA's approval, and the 
test method results will prevail over manufacturer's formulation data 
for compliance purposes. If you use the emission rate with add-on 
controls option, you need to determine the mass of organic HAP and 
volume fraction of coating solids as in the other two options and also 
the capture and control efficiencies of the add-on controls by means of 
a performance test. As part of this test, you must establish operating 
limits that can be used on a continuous basis to demonstrate compliance 
with the emission limit. The final rule specifies the parameters to 
monitor for the types of emission control systems commonly used in the 
industry. If the monitoring results indicate no deviations from the 
operating limits, you would assume the control system is continuing to 
provide the same control efficiency as demonstrated in the test. If the 
combination of this efficiency and the total mass of organic HAP in 
materials used in controlled coating operations continues to be within 
the applicable emission limit, then continuous compliance is shown for 
those operations.

E. What Are the Notification, Recordkeeping, and Reporting 
Requirements?

    If you are subject to the standards, you must comply with the 
applicable requirements in the NESHAP General Provisions, subpart A of 
40 CFR part 63. The General Provisions notification requirements 
include: initial notifications, notification of performance test if you 
are complying using a capture system and control device, Notification 
of Compliance Status, and additional notifications for affected sources 
with continuous monitoring systems. The General Provisions also require 
certain records and periodic reports. Records must be kept for at least 
5 years with 2 years of that time being at the facility, and they may 
be kept in electronic form as long as they are readily available for 
review.

IV. What Are the Environmental, Energy, Cost, and Economic Impacts?

A. What Are the Air Impacts?

    We estimate that nationwide organic HAP emissions will be reduced 
by approximately 1.080 megagrams/year (Mg/yr) (1,191 tpy) from existing 
sources. This represents a 45 percent reduction from the emissions 
baseline of 2,394 Mg/yr (2,639 tpy).
    For new sources, we are assuming that most will use state-of-the-
art coatings (predominantly powder coatings) even in the absence of the 
standards. These coatings will produce emission levels at or below the 
requirements of the final standards. Therefore, we are not attributing 
any emissions reductions from new sources to the final standards.

B. What Are the Non-Air Health, Environmental, and Energy Impacts?

    As at proposal, we have found that there are no significant 
expected non-air health, environmental, or energy impacts associated 
with the final standards. We reached this conclusion by considering the 
likely control approaches that will be used by existing and new 
sources. The use of low-HAP coating technologies will not produce any 
significant impacts on health, energy requirements, or the environment.

C. What Are the Cost and Economic Impacts?

    The costs for facilities to comply with the final standards result 
from the switch to reformulated (lower-HAP) coatings, thinners, and 
cleaning materials. There will also be annual costs for meeting the 
monitoring, recordkeeping, and reporting (MRR) requirements of the 
rule.
    For existing sources, the total nationwide annual cost in the 5th 
year of the standards is estimated to be $1.63 million. This includes 
approximately $0.48 million of direct costs associated with materials 
usage and $1.15 million for recordkeeping and reporting.
    For new sources, only the costs of MRR apply. We estimate the 
annual cost in the 5th year for all new sources to be $341,000.
    Our economic impact analysis showed the economic impacts of the 
promulgated standards to generally be minimal, with projected price 
increases and production decreases of less than 0.01 percent. Social 
costs are estimated at approximately $1.62 million in the 5th year for 
existing sources, with the burden being shared fairly equally between 
consumers and producers. No firms or facilities are expected to become 
at risk of closure due to the final standards. For more information, 
consult the ``Economic Impact Analysis of the Proposed NESHAP: Surface 
Coating of Large Appliances'' (Docket No. A-97-41).

V. What Are the Administrative Requirements?

A. Executive Order 12866, Regulatory Planning and Review

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA 
must determine whether the regulatory action is ``significant'' and 
therefore subject to the Office of Management and Budget (OMB) review 
and the requirements of

[[Page 48260]]

the Executive Order. The Executive Order defines ``significant 
regulatory action'' as one that is likely to result in a rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or tribal governments or 
communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligation of recipients 
thereof; or
    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    Pursuant to the terms of Executive Order 12866, it has been 
determined that this rule is not a ``significant regulatory action'' 
because none of the listed criteria apply to this action. Consequently, 
this action was not submitted to OMB for review under Executive Order 
12866.

B. Executive Order 13045, Protection of Children From Environmental 
Health Risks and Safety Risks

    Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any 
rule that: (1) Is determined to be ``economically significant'' as 
defined under Executive Order 12866, and (2) concerns an environmental 
health or safety risk that EPA has reason to believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, EPA must evaluate the environmental health or safety 
effects of the planned rule on children, and explain why the planned 
rule is preferable to other potentially effective and reasonably 
feasible alternatives considered by the Agency.
    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that are based on health or safety risks, such that 
the analysis required under section 5-501 of the Executive Order has 
the potential to influence the rule. These final standards are not 
subject to Executive Order 13045 because they do not establish an 
environmental standard based on an assessment of health or safety 
risks. No children's risk analysis was performed because no alternative 
technologies exist that would provide greater stringency at a 
reasonable cost. Furthermore, this rule has been determined not to be 
``economically significant'' as defined under Executive Order 12866.

C. Executive Order 13132, Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that 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.''
    This final rule 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, 
as specified in Executive Order 13132. Pursuant to the terms of 
Executive Order 13132, it has been determined that this rule does not 
have ``federalism implications'' because it does not meet the necessary 
criteria. Thus, Executive Order 13132 does not apply to this rule.

D. Executive Order 13175, Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.'' This final rule does not have 
tribal implications, as specified in Executive Order 13175. No tribal 
governments own or operate large appliance surface coating facilities. 
Thus, Executive Order 13175 does not apply to this rule.

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

    This rule is not subject to Executive Order 13211, ``Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use'' (66 FR 28355, May 22, 2001) because it is not a 
significant regulatory action under Executive Order 12866.

F. Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures by State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
1 year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective, or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective, or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    The EPA has determined that this final rule does not contain a 
Federal mandate that may result in expenditures of $100 million or more 
for State, local, and tribal governments, in the aggregate, or the 
private sector in any 1 year. The maximum total annual cost of this 
rule for any year has been estimated to be slightly less than $2 
million. Thus, today's final rule is not subject to the requirements of 
sections 202 and 205 of the UMRA. In addition, EPA has determined that 
these standards contain no regulatory requirements that might 
significantly or uniquely affect small governments because they contain 
no requirements that apply to such

[[Page 48261]]

governments or impose obligations upon them. Therefore, today's final 
rule is not subject to the requirements of section 203 of the UMRA.

G. Regulatory Flexibility Act (RFA), as Amended by the Small Business 
Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601, et 
seq.

    The RFA generally requires an agency to prepare a regulatory 
flexibility analysis of any rule subject to notice and comment 
rulemaking requirements under the Administrative Procedure Act or any 
other statute unless the agency certifies that the rule will not have a 
significant economic impact on a substantial number of small entities. 
Small entities include small businesses, small organizations, and small 
governmental jurisdictions.
    For the purposes of assessing the impacts of today's final rule on 
small entities, small entity is defined as: (1) A small business 
ranging from 100-1,000 employees or less than $3.5 million in annual 
sales; (2) a small governmental jurisdiction that is a government of a 
city, county, town, school district, or special district with a 
population of less than 50,000; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    In accordance with the RFA and SBREFA, EPA conducted an assessment 
of these standards on small businesses within the large appliance 
coating industry. Based on Small Business Administration size 
definitions and reported sales and employment data, EPA's survey 
identified 221 facilities that apply surface coatings to large 
appliances. These facilities, which include major and area sources, are 
owned by 84 companies. Of these companies, 34 are small businesses. 
Although small businesses represent about 40 percent of the companies 
within the source category, they are expected to incur only 10 percent 
of the total industry compliance costs. Under the final standards, the 
average annual compliance cost share of sales for small businesses is 
only 0.20 percent, with 26 of the 34 small businesses not expected to 
incur any additional costs because they are area sources or are 
permitted as synthetic minor HAP emission sources. After reviewing the 
range of costs to be borne by small businesses, EPA has determined the 
costs are typically small and that this action will not have a 
significant impact on a substantial number of small entities.
    Although this final rule will not have a significant economic 
impact on a substantial number of small entities, EPA has nonetheless 
worked aggressively to minimize the impact of these standards on small 
entities, consistent with our obligations under the CAA. We solicited 
input from small entities during the data-gathering phase of the 
proposed rulemaking. We are including compliance options that give 
small entities flexibility in choosing the most cost-effective and 
least burdensome alternative for their operation. For example, a 
facility could purchase and use low-HAP coatings (i.e., pollution 
prevention) that meet the final standards instead of using add-on 
capture and control systems. This method of compliance can be 
demonstrated with minimum burden by using purchase and usage records. 
No testing of materials will typically be required as the facility 
owner will be allowed to show that their coatings meet the emission 
limits by providing formulation data supplied by the manufacturer.

H. Paperwork Reduction Act

    The information collection requirements for these final standards 
will be submitted for approval to OMB under the Paperwork Reduction 
Act, 44 U.S.C. 3501, et seq. An Information Collection Request (ICR) 
document has been prepared by EPA (ICR No. 1954.01) and a copy may be 
obtained from Susan Auby by mail at U.S. EPA, Office of Environmental 
Information, Collection Strategies Division (2822T), 1200 Pennsylvania 
Avenue, NW, Washington, DC 20460, by e-mail at [email protected], or 
by calling (202) 566-1672. A copy may also be downloaded off the 
internet at http://www.epa.gov/icr. The information requirements are 
not effective until OMB approves them.
    The information requirements are based on notification, 
recordkeeping, and reporting requirements in the NESHAP General 
Provisions (40 CFR part 63, subpart A), which are mandatory for all 
operators subject to national emission standards. These recordkeeping 
and reporting requirements are specifically authorized by section 114 
of the CAA (42 U.S.C. 7414). All information submitted to EPA pursuant 
to the recordkeeping and reporting requirements for which a claim of 
confidentiality is made is safeguarded according to Agency policies set 
forth in 40 CFR part 2, subpart B.
    The final standards require maintaining records of all coatings, 
thinners, and cleaning materials data and calculations used to 
determine compliance. This information includes the volume used during 
each monthly compliance period, mass fraction organic HAP, density, 
and, for coatings only, volume fraction of coating solids.
    If an add-on control device is used, records must be kept of the 
capture efficiency of the capture system, destruction or removal 
efficiency of the add-on control device, and the monitored operating 
parameters. In addition, records must be kept of each calculation of 
the affected sourcewide emissions for each monthly compliance period 
and all data, calculations, test results, and other supporting 
information used to determine this value.
    The MRR burden in the 5th year after the effective date of the 
promulgated rule is estimated to be 32,000 labor hours at a cost of 
$1.50 million for new and existing sources.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or disclose or 
provide information to or for a Federal agency. This includes the time 
needed to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    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 EPA's 
rules are listed in 40 CFR part 9 and 48 CFR chapter 15. The OMB 
control number(s) for the information collection requirements in this 
rule will be listed in an amendment to 40 CFR part 9 or 48 CFR chapter 
15 in a subsequent Federal Register.

I. National Technology Transfer and Advancement Act

    As noted in the proposed rule, section 12(d) of the National 
Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 
104-113 (15 U.S.C. 272 note), directs the EPA to use voluntary 
consensus standards (VCS) in its regulatory activities unless to do so 
would be inconsistent with applicable law or otherwise impractical. The 
VCS are technical standards (e.g., materials specifications, test 
methods, sampling procedures, and business practices) that are 
developed or adopted by one or

[[Page 48262]]

more VCS bodies. The NTTAA directs EPA to provide Congress, through 
OMB, explanations when the Agency decides not to use available and 
applicable VCS.
    This rulemaking involves technical standards. The EPA cites the 
following standards in this rule: EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 
2G, 3, 3A, 3B, 4, 24, 25, 25A, 204, 204A-F, and 311. Consistent with 
the NTTAA, EPA conducted searches to identify VCS in addition to these 
EPA methods. No applicable VCS were identified for EPA Methods 1A, 2A, 
2D, 2F, 2G, 204, 204A-F, and 311. The search and review results have 
been documented and are placed in the docket (Docket No. A-97-41) for 
this rule.
    The four VCS described below were identified as acceptable 
alternatives to EPA test methods for the purposes of this rule.
    The VCS, ASME PTC 19-10-1981-Part 10, ``Flue and Exhaust Gas 
Analyses,'' is cited in this rule for its manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas. 
This part of ASME PTC 19-10-1981-Part 10 is an acceptable alternative 
to Method 3B.
    The VCS, ASTM 1475-98, ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products,'' is cited in this rule for 
determining the density of coatings and the volatile matter in 
coatings.
    The two VCS, ASTM D2697-86 (Reapproved 1998), ``Standard Test 
Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings,'' 
and ASTM D6093-97, ``Standard Test Method for Percent Volume 
Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium Gas 
Pycnometer,'' are cited in this rule as acceptable alternatives to EPA 
Method 24 to determine the volume solids content of coatings. 
Currently, EPA Method 24 does not have a procedure for determining the 
volume of solids in coatings. These standards augment the procedures in 
Method 24, which currently states that volume solids content be 
calculated from the coating manufacturer's formulation.
    Six VCS: ASTM D1475-90, ASTM D2369-95, ASTM D3792-91, ASTM D4017-
96a, ASTM D4457-85 (Reapproved 91), and ASTM D5403-93 are already 
incorporated by reference (IBR) in EPA Method 24. Five VCS: ASTM D1979-
91, ASTM D3432-89, ASTM D4747-87, ASTM D4827-93, and ASTM PS9-94 are 
IBR in EPA Method 311.
    In addition to the VCS EPA uses in this rule, the search for 
emissions measurement procedures identified eleven other VCS. The EPA 
determined that nine of these eleven standards identified for measuring 
emissions of the HAP or surrogates subject to emission standards in 
this rule were impractical alternatives to EPA test methods for the 
purposes of this rule. Therefore, EPA does not intend to adopt these 
standards for this purpose. For further information on the 
determination of the eleven methods, see the docket for this rulemaking 
(Docket A-97-41).
    Sections 63.4130, 63.4141, 63.4161, 63.4165, and 63.4166, and Table 
1 of subpart NNNN list the EPA testing methods included in the final 
standards. Under Sec. 63.7(f) of Subpart A of the General Provisions, a 
source may apply to EPA for permission to use alternative test methods 
in place of any of the EPA testing methods.

J. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801, et seq., as added by 
the Small Business Regulatory Enforcement Fairness Act of 1996, 
generally provides that before a rule may take effect, the agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of the Congress and to the Comptroller 
General of the United States. The EPA will submit a report containing 
this rule and other required information to the U.S. Senate, the U.S. 
House of Representatives, and the Comptroller General of the United 
States prior to publication of the rule in the Federal Register. A 
major rule cannot take effect until 60 days after it is published in 
the Federal Register. This action is not a major rule as defined by 5 
U.S.C. 804(2).

Subpart NNNN--National Emission Standards for Hazardous Air 
Pollutants: Surface Coating of Large Appliances

What This Subpart Covers


Sec. 63.4080  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants for large appliance surface coating facilities. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.


Sec. 63.4081  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
facility that applies coatings to large appliance parts or products, 
and is a major source, is located at a major source, or is part of a 
major source of emissions of hazardous air pollutants (HAP), except as 
provided in paragraph (d) of this section. A major source of HAP 
emissions is any stationary source or group of stationary sources 
located within a contiguous area and under common control that emits or 
has the potential to emit any single HAP at a rate of 9.07 megagrams 
(Mg) (10 tons) or more per year or any combination of HAP at a rate of 
22.68 Mg (25 tons) or more per year. You are not subject to this 
subpart if your large appliance surface coating facility is located at, 
or is part of, an area source of HAP emissions. An area source of HAP 
emissions is any stationary source or group of stationary sources 
located within a contiguous area and under common control that is not a 
major source.
    (b) The large appliance surface coating source category includes 
any facility engaged in the surface coating of a large appliance part 
or product. Large appliance parts and products include but are 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.
    (c) The large appliance surface coating activities and equipment to 
which this subpart applies are listed in paragraphs (c)(1) through (9) 
of this section:
    (1) Surface preparation of large appliance parts and products;
    (2) Preparation of a coating for application (e.g., mixing in 
thinners and other components);
    (3) Application of a coating to large appliance parts and products 
using, for example, spray guns or dip tanks;
    (4) Application of porcelain enamel, powder coating, and asphalt 
interior soundproofing coating;
    (5) Flash-off, drying, or curing following the coating application 
operation;
    (6) Cleaning of equipment used in coating operations (e.g., 
application equipment, hangers, racks);
    (7) Storage of coatings, thinners, and cleaning materials;
    (8) Conveying of coatings, thinners, and cleaning materials from 
storage areas to mixing areas or coating application areas, either 
manually (e.g., in buckets) or by automated means (e.g., transfer 
through pipes using pumps); and
    (9) Handling and conveying of waste materials generated by coating 
operations.
    (d) This subpart does not apply to surface coating that meets any 
of the criteria of paragraphs (d)(1) through (5) of this section.
    (1) The surface coating of large appliance parts such as metal or 
plastic handles, hinges, or fasteners that have a wider use beyond 
large appliances is not subject to this subpart.
    (2) The surface coating of large appliances conducted for the 
purpose of repairing or maintaining large appliances used by a facility 
and not for commerce is not subject to this subpart unless organic HAP 
emissions from the surface coating itself are as high as the rates 
specified in paragraph (a) of this section.
    (3) The surface coating of heat transfer coils or large commercial 
and industrial chillers.
    (4) The provisions of this subpart do not apply to research or 
laboratory facilities; janitorial, building, and facility maintenance 
operations; hobby shops operated for noncommercial purposes or coating 
applications using hand-held non-refillable aerosol containers.
    (5) The provisions of this subpart do not apply to processes 
involving metal plating or phosphating of a substrate.
    (e) If you own or operate an affected source that is subject to 
this subpart and at the same affected source you also perform surface 
coating subject to any other subparts in this part, you may choose for 
the affected source to comply with only one subpart. In order to choose 
this alternative, the total mass of organic HAP emissions from all 
surface coating operations in the affected source

[[Page 48264]]

must be less than or equal to the total mass of organic HAP emissions 
that would result if it complied separately with all applicable 
subparts. You must make this comparison for the initial compliance 
period and report it in the Notification of Compliance Status as 
required in Sec. 63.4110(b)(10) and in the Notification of Compliance 
Status required by the other subparts. If you choose this alternative, 
your demonstration of compliance with the other subpart constitutes 
compliance with this subpart.


Sec. 63.4082  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, and existing 
affected source.
    (b) The affected source is the collection of all of the items 
listed in paragraphs (b)(1) through (4) of this section that are part 
of the large appliance surface coating facility:
    (1) All coating operations as defined in Sec. 63.4181;
    (2) All storage containers and mixing vessels in which coatings, 
thinners, and cleaning materials are stored or mixed;
    (3) All manual and automated equipment and containers used for 
conveying coatings, thinners, and cleaning materials; and
    (4) All storage containers and all manual and automated equipment 
and containers used for conveying waste materials generated by a 
coating operation.
    (c) An affected source is a new affected source if you commenced 
its construction after July 23, 2002, and the construction is of a 
completely new large appliance surface coating facility where 
previously no large appliance surface coating facility had existed.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.


Sec. 63.4083  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source 
is specified in paragraphs (a) through (c) of this section. The 
compliance date begins the initial compliance period during which you 
conduct the initial compliance demonstration described in 
Secs. 63.4140, 63.4150, and 63.4160.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section.
    (1) If the initial startup of your new or reconstructed affected 
source is before July 23, 2002, the compliance date is July 23, 2002.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after July 23, 2002, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is July 
25, 2005.
    (c) For an area source that increases its emissions or its 
potential to emit such that it becomes a major source of HAP emissions, 
the compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source, or the date 
the area source becomes a major source, or July 23, 2002, whichever is 
latest.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or July 25, 2005, 
whichever is later.
    (d) You must meet the notification requirements in Sec. 63.4110 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

Emission Limitations


Sec. 63.4090  What emission limits must I meet?

    (a) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than 0.13 kilogram per liter 
(kg/liter) (1.1 pound per gallon (lb/gal)) of coating solids used 
during each compliance period.
    (b) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere to no more than 0.022 kg/liter 
(0.18 lb/gal) of coating solids used during each compliance period.


Sec. 63.4091  What are my options for meeting the emission limits?

    You must include all coatings, thinners, and cleaning materials 
used in the affected source when determining whether the organic HAP 
emission rate is equal to or less than the applicable emission limit in 
Sec. 63.4090. To make this determination, you must use at least one of 
the three compliance options listed in paragraphs (a) through (c) of 
this section. You may apply any of the compliance options to an 
individual coating operation or to multiple coating operations as a 
group or to the entire affected source. You may use different 
compliance options for different coating operations or at different 
times on the same coating operation. However, you may not use different 
compliance options at the same time on the same coating operation. If 
you switch between compliance options for any coating operation or 
group of coating operations, you must document this switch as required 
by Sec. 63.4130(c), and you must report it in the next semiannual 
compliance report required in Sec. 63.4120.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than 
or equal to the applicable emission limit in Sec. 63.4090, and that 
each thinner and each cleaning material used contains no organic HAP. 
You must meet all the requirements of Secs. 63.4140, 63.4141, and 
63.4142 to demonstrate compliance with the emission limit using this 
option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on data on the coatings, thinners, and cleaning materials used in 
the coating operation(s), the organic HAP emission rate for the coating 
operation(s) is less than or equal to the applicable emission limit in 
Sec. 63.4090. You must meet all the requirements of Secs. 63.4150, 
63.4151, and 63.4152 to demonstrate compliance with the emission limit 
using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on data on the coatings, thinners, and cleaning materials used in 
the coating operation(s) and the emission reductions achieved by 
emission capture and add-on controls, the organic HAP emission rate for 
the coating operation(s) is less than or equal to the applicable 
emission limit in Sec. 63.4090. If you use this compliance option, you 
must also demonstrate that all emission capture systems and add-on 
control devices for the coating operation(s) meet the operating limits 
required in Sec. 63.4092, except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to 
Sec. 63.4161(h), and that you meet the work practice standards required 
in Sec. 63.4093. You must meet all the requirements of Secs. 63.4160 
through 63.4168 to demonstrate compliance with the emission limits, 
operating limits, and work practice standards using this option.


Sec. 63.4092  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material

[[Page 48265]]

option or the emission rate without add-on controls option, you are not 
required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission rate with add-on controls option, except those for which you 
use a solvent recovery system and conduct a liquid-liquid material 
balance according to Sec. 63.4161(h), you must meet the operating 
limits specified in Table 1 to this subpart. These operating limits 
apply to the emission capture and control systems on the coating 
operation(s) for which you use this option, and you must establish the 
operating limits during the performance test according to the 
requirements in Sec. 63.4167. You must meet the operating limits at all 
times after you establish them.
    (c) If you use an add-on control device other than those listed in 
Table 1 to this subpart or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the U.S. 
Environmental Protection Agency (EPA) Administrator for approval of 
alternative monitoring under Sec. 63.8(f).


Sec. 63.4093  What work practice standards must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, 
you are not required to meet any work practice standards.
    (b) If you use the emission rate with add-on controls option, you 
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) for which you use this option; or you must 
meet an alternative standard as provided in paragraph (c) of this 
section. The plan must specify practices and procedures to ensure that, 
at a minimum, the elements specified in paragraphs (b)(1) through (5) 
of this section are implemented.
    (1) All organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be stored in closed containers.
    (2) Spills of organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be minimized.
    (3) Organic-HAP-containing coatings, thinners, cleaning materials, 
and waste materials must be conveyed from one location to another in 
closed containers or pipes.
    (4) Mixing vessels which contain organic-HAP-containing coatings 
and other materials must be closed except when adding to, removing, or 
mixing the contents.
    (5) Emissions of organic HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) As provided in Sec. 63.6(g), we, the EPA, may choose to grant 
you permission to use an alternative to the work practice standards in 
this section.

General Compliance Requirements


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

    (a) You must be in compliance with the emission limitations in this 
subpart as specified in paragraphs (a)(1) and (2) of this section.
    (1) Any coating operation(s) for which you use the compliant 
material option or the emission rate without add-on controls option, as 
specified in Sec. 63.4091(a) and (b), must be in compliance with the 
applicable emission limit in Sec. 63.4090 at all times.
    (2) Any coating operation(s) for which you use the emission rate 
with add-on controls option, as specified in Sec. 63.4091(c), must be 
in compliance with the applicable emission limit in Sec. 63.4090 and 
work practice standards in Sec. 63.4093 at all times. Each controlled 
coating operation must be in compliance with the operating limits for 
emission capture systems and add-on control devices required by 
Sec. 63.4092 at all times, except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to 
Sec. 63.4161(h).
    (b) You must always operate and maintain your affected source, 
including all air pollution control and monitoring equipment you use 
for purposes of complying with this subpart, according to the 
provisions in Sec. 63.6(e)(1)(i).
    (c) If your affected source uses an emission capture system and 
add-on control device, you must maintain a log detailing the operation 
and maintenance of the emission capture system, add-on control device, 
and continuous parameter monitors during the period between the 
compliance date specified for your affected source in Sec. 63.4083 and 
the date when the initial emission capture system and add-on control 
device performance tests have been completed as specified in 
Sec. 63.4160. This requirement does not apply to a solvent recovery 
system for which you conduct a liquid-liquid material balance according 
to Sec. 63.4161(h) in lieu of conducting performance tests.
    (d) If your affected source uses an emission capture system and 
add-on control device, you must develop and implement a written 
startup, shutdown, and malfunction plan according to the provisions in 
Sec. 63.6(e)(3). The plan must address the startup, shutdown, and 
corrective actions in the event of a malfunction of the emission 
capture system or the add-on control device. The plan must also address 
any coating operation equipment that may cause increased emissions or 
that would affect capture efficiency if the process equipment 
malfunctions, such as conveyors that move parts among enclosures.


Sec. 63.4101  What parts of the General Provisions apply to me?

    Table 2 to this subpart shows which parts of the General Provisions 
in Secs. 63.1 through 63.15 apply to you.

Compliance Requirements for the Compliant Material Option


Sec. 63.4140  By what date must I conduct the initial compliance 
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in 
Sec. 63.4141. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4083 and ends on the last day of 
the first full month after the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 
month. The initial compliance demonstration includes the determination 
according to Sec. 63.4141 and supporting documentation showing that, 
during the initial compliance period, you used no coating with an 
organic HAP content that exceeded the applicable emission limit in 
Sec. 63.4090, and that you used no thinners or cleaning materials that 
contained organic HAP.


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

    You may use the compliant material option for any individual 
coating operation, for any group of coating operations in the affected 
source, or for all the coating operations in the affected source. You 
must use either the emission rate without add-on controls option or the 
emission rate with add-on controls option for any coating operation(s) 
in the affected source for which you do not use this option. To 
demonstrate initial compliance using the compliant material option, the 
coating operation or group of coating operations must use no coating 
with an organic HAP content that exceeds the applicable emission limit 
in Sec. 63.4090 and must use no thinner or cleaning material that 
contains organic HAP, as determined according to this section during 
the initial compliance period. Any coating operation(s) for which you 
use the compliant material option is not required to meet the operating 
limits or work practice standards required in Secs. 63.4092 and 
63.4093, respectively. To demonstrate initial compliance with the 
emission limitations using the compliant material option, you must meet 
all the requirements of this section for the coating operation(s) using 
this option. Use the procedures in this section on each coating, 
thinner, and cleaning material in the condition it is in when it is 
received from its manufacturer or supplier and prior to any alteration. 
You do not need to redetermine the HAP content of coatings, thinners, 
or cleaning materials that have been reclaimed onsite and reused in the 
coating operation(s) for which you use the compliant material option, 
provided these materials in their condition as received were 
demonstrated to comply with the compliant material option. If the mass 
fraction of organic HAP of a coating equals zero, determined according 
to paragraph (a) of this section, and you use the compliant material 
option, you are not required to comply with

[[Page 48270]]

paragraphs (b) and (c) of this section for that coating.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the compliance 
period by using one of the options in paragraphs (a)(1) through (5) of 
this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the 
procedures specified in paragraphs (a)(1)(i) and (ii) of this section 
when performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic 
HAP compounds. For example, if toluene (not an OSHA carcinogen) is 
measured to be 0.5 percent of the material by mass, you do not have to 
count it. Express the mass fraction of each organic HAP you count as a 
value truncated to four places after the decimal point (for example, 
0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24 (appendix A to 40 CFR 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.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (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 that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent 
by mass or more for other organic HAP compounds. For example, if 
toluene (not an OSHA carcinogen) 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.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for mass fraction of organic HAP in these 
solvent blends listed in Table 3 or 4 of this subpart. If you use the 
tables, you must use the values in Table 3 for all solvent blends that 
match Table 3 entries, and you may only use Table 4 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 3, and you only know whether the blend is aliphatic or 
aromatic. However, if the results of a Method 311 test indicate higher 
values than those listed on Table 3 or 4 of this subpart, the Method 
311 results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by a test, by information provided by the 
supplier or the manufacturer of the material, or by calculation as 
specified in paragraphs (b)(1) through (3) of this section.
    (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use 
ASTM Method D2697-86 (Reapproved 1998), ``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.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.018

Where:

Vs = volume fraction of coating solids, liters coating 
solids per liter coating.
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 of 40 CFR 
part 60, 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 D1475-98, ``Standard Test Method for Density 
of Liquid Coatings, Inks, and Related Products'' (incorporated by 
reference, see Sec. 63.14) information from the supplier or 
manufacturer of the material, or reference sources providing density or 
specific gravity data for pure materials. If there is disagreement 
between ASTM Method D1475-98 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 D1475-98, ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products'' (incorporated by reference, see 
Sec. 63.14), information from the supplier or manufacturer of the 
material, or reference sources providing density or specific gravity 
data for pure materials. If there is disagreement between ASTM Method 
D1475-98 test results and other information sources, the test results 
will take precedence.
    (d) Determine the organic HAP content of each coating. Determine 
the organic HAP content, kg organic HAP per liter coating solids, of 
each coating used during the compliance period, using Equation 2 of 
this section, except that if the mass fraction of organic HAP equals 
zero, then the organic HAP content also equals zero and you are not 
required to use Equation 2 to calculate the organic HAP content:
[GRAPHIC] [TIFF OMITTED] TR23JY02.019

Where:

Hc = organic HAP content of the coating, kg organic HAP per 
liter coating solids.
Dc = density of coating, kg coating per liter coating, 
determined according to paragraph (c) of this section.

[[Page 48271]]

Wc = mass fraction of organic HAP in the coating, kg organic 
HAP per kg coating, determined according to paragraph (a) of this 
section.
Vs = volume fraction of coating solids, liters coating 
solids per liter coating, determined according to paragraph (b) of this 
section.

    (e) The organic HAP content for each coating used during the 
initial compliance period must be less than or equal to the applicable 
emission limit in Sec. 63.4090; and each thinner and cleaning material 
used during the initial compliance period must contain no organic HAP, 
determined according to paragraph (a) of this section. You must keep 
all records required by Secs. 63.4130 and 63.4131. As part of the 
Notification of Compliance Status required in Sec. 63.4110, you must 
identify the coating operation(s) for which you used the compliant 
material option and submit a statement that the coating operation(s) 
was (were) in compliance with the emission limitations during the 
initial compliance period because you used no coatings for which the 
organic HAP content exceeds the applicable emission limit in 
Sec. 63.4090, and you used no thinners or cleaning materials that 
contain organic HAP, determined according to paragraph (a) of this 
section.


Sec. 63.4142  How do I demonstrate continuous compliance with the 
emission limitations?

    (a) For each compliance period, to demonstrate continuous 
compliance, you must use no coating for which the organic HAP content, 
determined according to Sec. 63.4141(d), exceeds the applicable 
emission limit in Sec. 63.4090, and use no thinner or cleaning material 
that contains organic HAP, determined according to Sec. 63.4141(a). 
Each month following the initial compliance period described in 
Sec. 63.4140 is a compliance period.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in 
paragraph (a) of this section is a deviation from the emission 
limitations that must be reported as specified in Secs. 63.4110(b)(6) 
and 63.4120(d).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4120, you must submit a statement that you were in compliance 
with the emission limitations during the reporting period because you 
used no thinners or cleaning materials that contained organic HAP, and 
you used no coatings for which the organic HAP content exceeded the 
applicable emission limit in Sec. 63.4090.
    (d) You must maintain records as specified in Secs. 63.4130 and 
63.4131.

Compliance Requirements for the Emission Rate Without Add-On Controls 
Option


Sec. 63.4150  By what date must I conduct the initial compliance 
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of 
Sec. 63.4151. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4083 and ends on the last day of 
the first full month after the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 
month. The initial compliance demonstration includes the calculations 
according to Sec. 63.4151 and supporting documentation showing that the 
organic HAP emission rate for the initial compliance period was equal 
to or less than the applicable emission limit in Sec. 63.4090.


Sec. 63.4151  How do I demonstrate initial compliance with the emission 
limitations?

    You may use the emission rate without add-on controls option for 
any individual coating operation, for any group of coating operations 
in the affected source, or for all of the coating operations in the 
affected source. You must use either the compliant material option or 
the emission rate with add-on controls option for any coating 
operation(s) in the affected source for which you do not use this 
option. To demonstrate initial compliance using the emission rate 
without add-on controls option, the coating operation(s) must meet the 
applicable emission limit in Sec. 63.4090 but not the operating limits 
or work practice standards in Secs. 63.4092 and 63.4093, respectively, 
during the initial compliance period. You must meet all of the 
requirements of this section to demonstrate initial compliance with the 
applicable emission limit in Sec. 63.4090 for the coating operation(s). 
When calculating the organic HAP emission rate according to this 
section, do not include any coatings, thinners, or cleaning materials 
used on coating operations for which you use the compliant material 
option or the emission rate with add-on controls option. You do not 
need to redetermine the mass of organic HAP in coatings, thinners, or 
cleaning materials that have been reclaimed onsite and reused in the 
coating operation(s) for which you use the emission rate without add-on 
controls option.
    (a) Determine the mass fraction of organic HAP for each material.

of each coating, thinner, and cleaning material used during the 
compliance period according to the requirements in Sec. 63.4141(c).
    (d) Determine the volume of each material used during the 
compliance period. Determine the volume (liters) of each coating, 
thinner, and cleaning material used during the compliance period by 
measurement or usage records.
    (e) Calculate the mass of organic HAP emissions during the 
compliance period. The mass of organic HAP emissions is the combined 
mass of organic HAP contained in all coatings, thinners, and cleaning 
materials used during the compliance period minus the organic HAP in 
certain waste materials. Calculate it using Equation 1 of this section.
[GRAPHIC] [TIFF OMITTED] TR23JY02.000

Where:

He = total mass of organic HAP emissions during the 
compliance period, kg.
A = total mass of organic HAP in the coatings used during the 
compliance period, kg, as calculated in Equation 1A of this section.

sent to a TSDF. If you choose to account for the mass of organic HAP 
contained in waste materials sent or designated for shipment to a 
hazardous waste TSDF in the calculation of the mass of organic HAP 
emissions (Equation 1 of this section), then you must determine it 
according to paragraphs (e)(4)(i) through (v) of this section.
    (i) You may include in the determination of organic HAP in waste 
materials only the waste materials that are generated by coating 
operations for which you use Equation 1 of this section and that will 
be treated or disposed of by a facility that is regulated as a TSDF 
under 40 CFR part 262, 264, 265, or 266. The TSDF may be either off-
site or on-site. You may not include in the determination the organic 
HAP contained in wastewater.
    (ii) You must determine either the amount of waste materials sent 
to a TSDF during the compliance period or the amount collected and 
stored during the compliance period and designated for future transport 
to a TSDF. Do not include in your determination any waste materials 
sent to a TSDF during a compliance period if you have already included 
them in the amount collected and stored during that compliance period 
or a previous compliance period.
    (iii) Determine the total mass of organic HAP contained in the 
waste materials specified in paragraph (e)(4)(ii) of this section.
    (iv) You must document your methodology to determine the amount of 
waste materials and the total mass of organic HAP they contain, as

period, liters, as calculated by Equation 2 of this section.

    (h) The organic HAP emission rate for the initial compliance period 
must be less than or equal to the applicable emission limit in 
Sec. 63.4090. You must keep all records as required by Secs. 63.4130 
and 63.4131. As part of the Notification of Compliance Status required 
by Sec. 63.4110, you must identify the coating operation(s) for which 
you used the emission rate without add-on controls option and submit a 
statement that the coating operation(s) was (were) in compliance with 
the emission limitations during the initial compliance period because 
the organic HAP emission rate was less than or equal to the applicable

initial compliance period described in Sec. 63.4150 is a compliance 
period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4090, this is a 
deviation from the emission limitations for that compliance period and 
must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(e).
    (c) As part of each semiannual compliance report required by

Compliance Requirements for the Emission Rate With Add-On Controls 
Option


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

    (a) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (a)(1) through (3) of this 
section.
    (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. 63.4183. 
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 Secs. 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.

specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date. If the compliance date occurs on any 
day other than the first day of a month, then the initial compliance 
period extends through the end of that month plus the next month. The 
initial compliance demonstration includes the results of emission 
capture system and add-on control device performance tests conducted 
according to Secs. 63.4164, 63.4165, and 63.4166; results of liquid-
liquid material balances conducted according to Sec. 63.4161(h);

Sec. 63.4093.
    (b) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (b)(1) through (4) this section.
    (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. 63.4183. 
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 Secs. 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. 63.4183. For a solvent recovery system for which you conduct

initiate the first material balance no later than 180 days after the 
applicable compliance date specified in Sec. 63.4183.
    (2) You must develop and begin implementing the work practice plan 
required by Sec. 63.4093 no later than the compliance date specified in 
Sec. 63.4083.
    (3) You must complete the compliance demonstration for the initial 
compliance period according to the requirements of Sec. 63.4161. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date, or the date you conduct the 
performance tests of the emission capture systems and add-on control 
devices, or initiate the first liquid-liquid material balance for a 
solvent recovery system; whichever is later. The initial compliance 
demonstration includes the results of emission capture system and add-
on control device performance tests conducted according to 
Secs. 63.4164, 63.4165, and 63.4166; results of liquid-liquid material 
balances conducted according to Sec. 63.4161(h); calculations according 
to Sec. 63.4161 and supporting documentation showing that, during the 
initial compliance period, the organic HAP emission rate was equal to 
or less than the emission limit in Sec. 63.4090(b); the operating 
limits established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.4168; and 
documentation of whether you developed and implemented the work 
practice plan required by Sec. 63.4093.
    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by 
Sec. 63.4092 until after you have completed the performance tests 
specified in paragraph (b)(1) of this section. Instead, you must 
maintain a log detailing the operation and maintenance of the emission 
capture system, add-on control device, and continuous parameter 
monitors during the period between the compliance date and the 
performance test. You must begin complying with the operating limits 
for your affected source on the date you complete the performance tests 
specified in paragraph (b)(1) of this section. This requirement does 
not apply to solvent recovery systems for which you conduct liquid-
liquid material balances according to Sec. 63.4161(h).


Sec. 63.4161  How do I demonstrate initial compliance?

    You may use the emission rate with add-on controls option for any 
coating operation, for any group of coating operations in the affected 
source, or for all of the coating operations in the affected source. 
You may include both controlled and uncontrolled coating operations in 
a group for which you use this option. You must use either the 
compliant material option or the emission rate without add-on controls 
option for any coating operation(s) in the affected source for which 
you do not use this option. To demonstrate initial compliance, the 
coating operation(s) for which you use the emission rate with add-on 
controls option must meet the applicable emission limit in Sec. 63.4090 
and the work practice standards required in Sec. 63.4093; and each 
controlled coating operation must meet the operating limits required in 
Sec. 63.4092. You must meet all the requirements of this section to 
demonstrate initial compliance with the emission limitations. When 
calculating the organic HAP emission rate according to this section, do 
not include any coatings, thinners, or cleaning materials used on 
coating operations for which you use the compliant material option or 
the emission rate without add-on controls option. You do not need to 
redetermine the mass of organic HAP in coatings, thinners, or cleaning 
materials that have been reclaimed onsite and reused in the coating 
operation(s) for which you use the emission rate with add-on controls 
option.
    (a) Except as provided in Sec. 63.4160(b)(4) and except for solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to the requirements of Sec. 63.4161(h), you must establish 
and demonstrate continuous compliance

[[Page 48274]]

during the initial compliance period with the operating limits required 
by Sec. 63.4092, using the procedures specified in Secs. 63.4167 and 
63.4168.
    (b) You must develop, implement, and document your implementation 
of the work practice plan required by Sec. 63.4093 during the initial 
compliance period as specified in Sec. 63.4130.
    (c) You must follow the procedures in paragraphs (d) through (l) of 
this section to demonstrate compliance with the applicable emission 
limit in Sec. 63.4090.
    (d) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.4151(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner, and 
cleaning material used during the compliance period, and the volume 
fraction of coating solids for each coating used during the compliance 
period.
    (e) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4151, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during the compliance period in 
the coating operation or group of coating operations for which you use 
the emission rate with add-on controls option.
    (f) Calculate the organic HAP emission reduction for each 
controlled coating operation. Determine the mass of organic HAP 
emissions reduced for each controlled coating operation during the 
compliance period. The emissions reduction determination quantifies the 
total organic HAP emissions that pass through the emission capture 
system and are destroyed or removed by the add-on control device. Use 
the procedures in paragraph (g) of this section to calculate the mass 
of organic HAP emissions reduction 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. For each controlled coating operation using a 
solvent recovery system for which you conduct a liquid-liquid material 
balance, use the procedures in paragraph (h) of this section to 
calculate the organic HAP emissions reduction.
    (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, including a 
deviation during a period of startup, shutdown, or malfunction, 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.

Notification of Compliance Status required by Sec. 63.4110, you must 
identify the coating operation(s) for which you used the emission rate 
with add-on controls option and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate was less than or equal to the applicable emission limit in 
Sec. 63.4090, and you achieved the operating limits required by 
Sec. 63.4092 and the work practice standards required by Sec. 63.4093.


Sec. 63.4162  [Reserved]


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

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.4090, the organic HAP emission rate for each 
compliance period determined according to the procedures in 
Sec. 63.4161 must be equal to or less than the applicable emission 
limit in Sec. 63.4090. Each month following the initial compliance 
period described in Sec. 63.4160 is a compliance period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4090, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(g).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4092 that applies to you as specified in 
Table 1 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating 
limit that must be reported as specified in Secs. 63.4110(b)(6) and 
63.4120(g).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4161, 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 calculation of organic HAP emissions reductions 
in Equation 1 of Sec. 63.4161.
    (d) You must meet the requirements for bypass lines in 
Sec. 63.4168(b). If any bypass line is opened and emissions are 
diverted to the atmosphere when the coating operation is running, this 
is a deviation that must be reported as specified in 
Secs. 63.4110(b)(6) and 63.4120(g). For the purposes of completing the 
compliance calculations specified in Sec. 63.4161, 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 
calculation of organic HAP emissions reductions in Equation 1 of 
Sec. 63.4161.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4093. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4130(k)(9), this is a deviation from 
the work practice standards that must be reported as specified in 
Secs. 63.4110(b)(6) and 63.4120(g).
    (f) As part of each semiannual compliance report required in 
Sec. 63.4120, you must submit a statement that you were in compliance 
with the emission limitations during the reporting period because the 
organic HAP emission rate for each compliance period was less than or 
equal to the applicable emission limit in Sec. 63.4090, and you 
achieved the operating limits required by Sec. 63.4092 and the work 
practice standards required by Sec. 63.4093 during each compliance 
period.
    (g) During periods of startup, shutdown, and malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency, you must 
operate in accordance with the SSMP required by Sec. 63.4100(d).
    (h) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with the SSMP. The Administrator will 
determine whether deviations that occur during a period of startup, 
shutdown, or malfunction are violations according to the provisions in 
Sec. 63.6(e).
    (i) [Reserved]
    (j) You must maintain records as specified in Secs. 63.4130 and 
63.4131.


Secs. 63.4130 and 63.4131.    


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 Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the 
performance test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under

[[Page 48277]]

representative operating conditions for the coating operation. 
Operations during periods of startup, shutdown, or malfunction and 
periods of nonoperation do not constitute representative conditions. 
You must record the process information that is necessary to document 
operating conditions during the test and explain why the conditions 
represent normal operation.
    (2) Representative emission capture system and add-on control 
device operating conditions. You must conduct the performance test when 
the emission capture system and add-on control device are operating at 
a representative flow rate, and the add-on control device is operating 
at a representative inlet concentration. You must record information 
that is necessary to document emission capture system and add-on 
control device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4165 and of an add-on 
control device according to the requirements in Sec. 63.4166.
    (c) The performance test to determine add-on control device organic 
HAP destruction or removal efficiency must consist of three runs as 
specified in Sec. 63.7(e)(3) and each run must last at least 1 hour.


Sec. 63.4165  How do I determine the emission capture system 
efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required 
by Sec. 63.4160.
    (a) You may assume the capture system efficiency is 100 percent if 
both of the conditions in paragraphs (a)(1) and (2) of this section are 
met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from 
the enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating 
solvent flash-off and coating, curing, and drying occurs within the 
capture system and the removal or evaporation of cleaning materials 
from the surfaces they are applied to occurs within the capture system. 
For example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) If the capture system does not meet both of the criteria in 
paragraphs (a)(1) and (2) of this section, then you must use one of the 
three protocols described in paragraphs (c), (d), and (e) of this 
section to measure capture efficiency. The capture efficiency 
measurements use TVH capture efficiency as a surrogate for organic HAP 
capture efficiency. For the protocols in paragraphs (c) and (d) of this 
section, the capture efficiency measurement must consist of three test 
runs. Each test run must be at least 3 hours duration or the length of 
a production run, whichever is longer, up to 8 hours. For the purposes 
of this test, a production run means the time required for a single 
part to go from the beginning to the end of production which includes 
surface preparation activities and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation, to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure 
around the coating operation where coatings, thinners, and cleaning 
materials are applied, and all areas where emissions from these applied 
coatings and materials subsequently occur, such as flash-off, curing, 
and drying areas. The areas of the coating operation where capture 
devices collect emissions for routing to an add-on control device, such 
as the entrance and exit areas of an oven or spray booth, must also be 
inside the enclosure. The enclosure must meet the applicable definition 
of a temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner, and cleaning material used in the coating operation during 
each capture efficiency test run. To make the determination, substitute 
TVH for each occurrence of the term VOC in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners, and cleaning 
materials used in the coating operation during each capture efficiency 
test run.
[GRAPHIC] [TIFF OMITTED] TR23JY02.013

Where:

TVHused = total mass of TVH liquid input from all coatings, 
thinners, and cleaning materials used in the coating operation during 
the capture efficiency test run, kg.
TVHi = mass fraction of TVH in coating, thinner, or cleaning 
material, i, that is used in the coating operation during the capture 
efficiency test run, kg TVH per kg material.
Voli = total volume of coating, thinner, or cleaning 
material, i, used in the coating operation during the capture 
efficiency test run, liters.
Di = density of coating, thinner, or cleaning material, i, 
kg material per liter material.
n = number of different coatings, thinners, and cleaning materials used 
in the coating operation during the capture efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total 
enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound 
emitting operations inside the building enclosure, other than the 
coating operation for which capture efficiency is being determined must 
be shut down, but all fans and blowers must be operating normally.

[[Page 48278]]

    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.014

Where:

CE = capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHused = total mass of TVH liquid input used in the coating 
operation during the capture efficiency test run, kg.
TVHuncaptured = total mass of TVH that is not captured by 
the emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure 
around the coating operation where coatings, thinners, and cleaning 
materials are applied and all areas where emissions from these applied 
coatings and materials subsequently occur such as flash-off, curing, 
and drying areas. The areas of the coating operation where capture 
devices collect emissions generated by the coating operation for 
routing to an add-on control device, such as the entrance and exit 
areas of an oven or a spray booth, must also be inside the enclosure. 
The enclosure must meet the applicable definition of a temporary total 
enclosure or building enclosure in Method 204 of appendix M to 40 CFR 
part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement 
must be upstream from the add-on control device and must represent 
total emissions routed from the capture system and entering the add-on 
control device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total 
enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound 
emitting operations inside the building enclosure other than the 
coating operation for which capture efficiency is being determined must 
be shut down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.015

Where:

CE = capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHcaptured = total mass of TVH captured by the emission 
capture system as measured at the inlet to the add-on control device 
during the emission capture efficiency test run, kg.
TVHuncaptured = total mass of TVH that is not captured by 
the emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO 
or LCL approach as described in appendix A to subpart KK of this part.


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

    (a) For all types of add-on control devices, use the test methods 
as specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR 
part 60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You 
may also use as an alternative to Method 3B, the manual method for 
measuring the oxygen, carbon dioxide, and carbon monoxide content of 
exhaust gas in ANSI/ASME, PTC 19.10-1981, ``Flue

[[Page 48279]]

and Exhaust Gas Analyses'' (incorporated by reference, see Sec. 63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (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 of appendix A to 40 CFR 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.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator 
with an outlet for the high-volume, dilute stream that has been treated 
by the concentrator, and a second add-on control device is an oxidizer 
with an outlet for the low-volume, concentrated stream that is treated 
with the oxidizer, you must measure emissions at the outlet of the 
oxidizer and the high-volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic 
emissions mass flow rates for the inlet and the outlet of the add-on 
control device, using Equation 1 of this section. If there is more than 
one inlet or outlet to the add-on control device, you must calculate 
the total gaseous organic mass flow rate using Equation 1 of this 
section for each inlet and each outlet and then total all of the inlet 
emissions and total all of the outlet emissions.

Sec. 63.4167  How do I establish the emission capture system and add-on 
control device operating limits during the performance test?

    During the performance test required by Sec. 63.4160 and described 
in Secs. 63.4164, 63.4165, and 63.4166, you must establish the 
operating limits required by Sec. 63.4092 according to this section 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.4092.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of 
the three test runs. You must monitor the temperature in the firebox of 
the thermal oxidizer or immediately downstream of the firebox before 
any substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained 
during the performance test. These are the minimum operating limits for 
your catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature just before 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, 
at a minimum, the elements specified in paragraphs (b)(4)(i) through 
(iii) of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems and, as necessary, 
adjusting the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine

[[Page 48280]]

destruction efficiency according to Sec. 63.4166.
    (c) Carbon adsorbers. If your add-on control device is a carbon 
absorber, establish the operating limits according to paragraphs (c)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing 
gas (e.g., steam or nitrogen) mass flow for each regeneration cycle and 
the carbon bed temperature after each carbon bed regeneration and 
cooling cycle for the regeneration cycle either immediately preceding 
or immediately following the performance test.
    (2) The operating limits for your carbon absorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle 
and the maximum carbon bed temperature recorded after the cooling 
cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) 
of this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least 
once every 15 minutes during each of the three runs of the performance 
test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4165(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by 
Sec. 63.4160 and described in Secs. 63.4164 and 63.4165, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the 
add-on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.


Sec. 63.4168  What are the requirements for continuous parameter 
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section 
according to paragraphs (a)(1) through (6) of this section. You must 
install, operate, and maintain each CPMS specified in paragraphs (b) 
and (d) of this section according to paragraphs (a)(3) through (5) of 
this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for 
each successive 3-hour period of the emission capture system and add-on 
control device operation except as specified in paragraph (a)(6) of 
this section.
    (3) You must record the results of each inspection, calibration, 
and validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating except during monitoring malfunctions, 
associated repairs, and required quality assurance or control 
activities (including, if applicable, calibration checks and required 
zero and span adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You 
must use all the data collected during all other periods in calculating 
the data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Except for periods of required 
quality assurance or control activities, any period during which the 
CPMS fails to operate and record data continuously as required by 
paragraph (a)(1) of this section, or generates data that cannot be 
included in calculating averages as specified in paragraph (a)(6) of 
this section, is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must comply with the 
requirements of paragraphs (a)(3) through (5) and (b)(1) and (2) of 
this section for each emission capture system that contains bypass 
lines that could divert emissions away from the add-on control device 
to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must 
be recorded, as well as every time the flow direction is changed. The 
flow control position indicator must be installed at the entrance to 
any bypass line that could divert the emissions away from the add-on 
control device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass 
line valve in the closed position with a car-seal or a lock-and-key 
type configuration. You

[[Page 48281]]

must visually inspect the seal or closure mechanism at least once every 
month to ensure that the valve is maintained in the closed position and 
the emissions are not diverted away from the add-on control device to 
the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve 
is in the closed (non-diverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the 
monitoring system at least once every month to verify that the monitor 
will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shutdown the coating operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.4120.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (a) and (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in 
the firebox of the thermal oxidizer or in the duct immediately 
downstream of the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor in 
the gas stream immediately before the catalyst bed, and if you 
establish operating limits according to Sec. 63.6167(b)(1) and (2), 
also install a gas temperature monitor in the gas stream immediately 
after the catalyst bed.
    (3) For each gas temperature monitoring device, you must comply

sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a 
reading within 30 degrees Fahrenheit of the process temperature 
sensor's reading.
    (vi) Any time the sensor exceeds the manufacturer's specified 
maximum operating temperature range, either conduct calibration and 
validation checks or install a new temperature sensor.
    (vii) At least monthly, inspect components for integrity and 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (d) Carbon adsorbers. If you are using a carbon adsorber as an add-
on control device, you must monitor the total regeneration desorbing 
gas (e.g., steam or nitrogen) mass flow for each regeneration cycle,

the General Provisions of this part, and in this section as follows:
    Add-on control device means an air pollution control device, such 
as a thermal oxidizer or carbon absorber, that reduces pollution in an

(expressed as a percentage) of the pollutants from an emission source 
that is delivered to an add-on control device.
    Capture system means one or more capture devices intended to 
collect emissions generated by a coating operation in the use of 
coatings and cleaning materials, both at the point of application and 
at subsequent points where emissions from the coatings and cleaning 
materials occur, such as flashoff, drying, or curing. As used in this 
subpart, multiple capture devices that collect emissions generated by a 
coating operation are considered a single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting) from a substrate before or after coating application

cleaning materials used for substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. For the purposes of this subpart, 
coatings include paints, porcelain enamels, sealants, caulks, inks,

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. Applications of coatings using hand-held, nonrefillable aerosol

add-on control device parameters.
    Controlled coating operation means a coating operation from which 
some or all of the organic HAP emissions are routed through an emission 
capture system and add-on control device.

VOC due to negligible photochemical reactivity. The exempt compounds 
are listed in 40 CFR 51.100(s).
    Facility maintenance means the routine repair or refurbishing 
(including surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of the facility or that are 
necessary for the facility to function in its intended capacity. It 
does not mean cleaning of equipment that is part of a large appliances 
coating operation.
    Heat transfer coil means a tube-and-fin assembly used in large

than based on testing of the material with the test methods specified 
in Sec. 63.4141. Manufacturer's formulation data may include, but are 
not limited to, information on density, organic HAP content, volatile 
organic matter content, and coating solids content.
    Mass fraction of organic HAP means the ratio of the mass of organic 
HAP to the mass of a material in which it is contained, expressed as kg 
organic HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 to 35 
days to allow for flexibility in recordkeeping when data are based on a 
business accounting period.
    Organic HAP content means the mass of organic HAP per volume of 
coating solids for a coating, calculated using Equation 2 of 
Sec. 63.4141. The organic HAP content is determined for the coating in 
the condition it is in when received from its manufacturer or supplier 
and does not account for any alteration after receipt.
    Permanent total enclosure (PTE) means a permanently installed 
enclosure that meets the criteria of Method 204 of appendix M, 40 CFR 
part 51, for a PTE and that directs all the exhaust gases from the 
enclosure to an add-on control device.
    Protective oil means an organic material that is applied to a 
substrate for the purpose of providing lubrication or protection from 
corrosion without forming a solid film. This definition of protective 
oils includes, but is not limited to, lubricating oils, evaporative 
oils (including those that evaporate completely), and extrusion oils.
    Research or laboratory facility means a facility whose primary 
purpose is for research and development of new processes and products 
conducted under the close supervision of technically trained personnel 
and is not engaged in the manufacture of final or intermediate products 
for commercial purposes, except in a de minimis manner.
    Responsible official means responsible official as defined in 40 
CFR 70.2.
    Startup, initial means the first time equipment is brought online 
in a facility.
    Surface preparation means use of a cleaning material on a portion 
of or all of a substrate including use of cleaning material to remove 
dried coating which is sometimes called ``depainting.''
    Temporary total enclosure means an enclosure constructed for the 
purpose of measuring the capture efficiency of pollutants emitted from 
a given source as defined in Method 204 of appendix M, 40 CFR part 51.
    Thinner means an organic solvent that is added to a coating after 
the coating is received from the supplier.
    Total volatile hydrocarbon (TVH) means the total amount of 
nonaqueous volatile organic matter determined according to Methods 204 
and 204A through 204F of appendix M to 40 CFR part 51 and substituting 
the term TVH each place in the methods where the term VOC is used. The 
TVH includes both VOC and non-VOC.
    Uncontrolled coating operation means a coating operation from which 
no organic HAP emissions are routed through an emission capture system 
and add-on control device.
    Volatile organic compound (VOC) means any compound defined as VOC 
in 40 CFR 51.100(s).
    Volume fraction of coating solids means the ratio of the volume of 
coating solids (also known as volume of nonvolatiles) to the volume of 
coating, expressed as liters of coating solids per liter of coating.
    Wastewater means water that is generated in a coating operation and 
is collected, stored, or treated prior to being discarded or 
discharged.
