AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving a 
revision to the Commonwealth of Pennsylvania's state implementation 
plan (SIP). The revision includes amendments to the Pennsylvania 
Department of Environmental Protection's (PADEP) regulations and 
addresses the requirement to adopt reasonably available control 
technology (RACT) for sources covered by EPA's control techniques 
guidelines (CTG) standards for the following categories: Miscellaneous 
metal parts surface coating, miscellaneous plastic parts surface 
coating, and pleasure craft surface coatings, as well as related 
cleaning activities. The SIP revision also amends regulations for 
graphic arts systems and mobile equipment repair and refinishing as 
well as making general administrative changes. This action is being 
taken under the Clean Air Act (CAA).

DATES: This final rule is effective on September 10, 2018.

ADDRESSES: EPA has established a docket for this action under Docket ID 
Number EPA-R03-OAR-2017-0437. All documents in the docket are listed on

SUPPLEMENTARY INFORMATION: On November 18, 2016, PADEP submitted a 
revision to the Pennsylvania SIP concerning the adoption of EPA's CTG 
for miscellaneous metal parts surface coating processes, miscellaneous 
plastic parts surface coating processes, and pleasure craft surface 
coatings. Specifically, PADEP has amended 25 Pennsylvania Code (Pa. 
Code) Chapter 129 (relating to standards for sources) to address RACT 
and further reduce volatile organic compounds (VOC) emissions in 
Pennsylvania. In accordance with sections 172(c)(1), 182(b)(2)(A) and 
184(b)(1)(B) of the CAA, Pennsylvania's SIP revision submittal 
establishes VOC emission limitations and other requirements consistent 
with the recommendations of EPA's 2008 Control Techniques Guidelines 
for Miscellaneous Metal and Plastic Parts Coatings (MMPP) (Publication 
No. EPA 453/R-08-003; September 2008) and Control Techniques Guidelines 
for Automobile and Light-Duty Truck Assembly Coatings for these sources 
in the Commonwealth of Pennsylvania (Publication No. EPA 453/R-08-006).

[[Page 39601]]

I. Background

    Ground level ozone is formed in the atmosphere by photochemical 
reactions between volatile organic compounds (VOCs), nitrogen oxides 
(NOX), and carbon monoxide (CO) in the presence of sunlight. 
In order to reduce ozone concentrations in the ambient air, the CAA 
requires all nonattainment areas to apply controls on VOC and 
NOX emission sources to achieve emission reductions. Among 
effective control measures, RACT controls significantly reduce VOC and 
NOX emissions from major stationary sources. NOX 
and VOC are referred to as ozone precursors and are emitted by many 
types of pollution sources, including motor vehicles, power plants, 
industrial facilities, and area wide sources, such as consumer products 
and lawn and garden equipment. Scientific evidence indicates that 
adverse public health effects occur following exposure to ozone. These 
effects are more pronounced in children and adults with lung disease. 
Breathing air containing ozone can reduce lung function and inflame 
airways, which can increase respiratory symptoms and aggravate asthma 
or other lung diseases.
    RACT is defined as the lowest emission limitation that a particular 
source is capable of meeting by the application of control technology 
that is reasonably available considering technological and economic 
feasibility. 44 FR 53761 at 53762 (September 17, 1979). Section 182 of 
the CAA sets forth two separate RACT requirements for ozone 
nonattainment areas. The first requirement, contained in section 
182(a)(2)(A) of the CAA, and referred to as RACT fix-up, requires the 
correction of RACT rules for which EPA identified deficiencies before 
the CAA was amended in 1990. Pennsylvania previously corrected its 
deficiencies under the 1-hour ozone standard and has no further 
deficiencies to correct under this section of the CAA. The second 
requirement in section 182(b)(2) of the CAA applies to moderate (or 
worse) ozone nonattainment areas, and pursuant to section 184(b)(1)(B), 
to all areas in a state that are included in an ozone transport region 
(OTR). Section 184 of the CAA includes all of Pennsylvania in the OTR. 
Sections 182(b)(2) and 184(b) require these areas to implement RACT 
controls on all major VOC and NOX emission sources and on 
all sources and source categories covered by a CTG issued by EPA.\1\ 
See CAA sections 182(b)(2) and 184(b).
---------------------------------------------------------------------------

    \1\ CTGs are documents issued by EPA intended to provide state 
and local air pollution control authorities information to assist 
them in determining RACT for VOC from various sources. The 
recommendations in the CTG are based upon available data and 
information and may not apply to a particular situation based upon 
the circumstances. States can follow the CTG and adopt state 
regulations to implement the recommendations contained therein, or 
they can adopt alternative approaches. In either case, states must 
submit their RACT rules to EPA for review and approval as part of 
the SIP process. Pursuant to section 184(b)(1)(B) of the CAA, all 
areas in the OTR must implement RACT with respect to sources of VOCs 
in the state covered by a CTG issued before or after November 15, 
1990.
---------------------------------------------------------------------------

    In subsequent Federal Register notices, EPA has addressed how 
states can meet the RACT requirements of the CAA. EPA developed the CTG 
for MMPP in September 2008 (Publication No. EPA 453/R-08-003) that 
provides guidelines with regard to feasible emission limitations and 
operating practices for a number of different surface coatings used 
within this large and diverse source category. The 2008 MMPP CTG 
recommends separate sets of emission limits for metal parts coatings, 
plastic parts coatings, automotive/transportation and business machine 
plastic parts, and pleasure craft, depending on the type of coating 
used by a particular source. The miscellaneous metal product and 
plastic parts surface coatings categories identified pursuant to 
section 183(e) of the CAA include the coatings that are applied to the 
surfaces of a varied range of metal and plastic parts and products. 
Such parts or products are constructed either entirely or partially 
from metal or plastic. These miscellaneous metal products and plastic 
parts include, but are not limited to, metal and plastic components of 
the following types of products as well as the products themselves: 
Fabricated metal products, molded plastic parts, small and large farm 
machinery, commercial and industrial machinery and equipment, 
automotive or transportation equipment, interior or exterior automotive 
parts, construction equipment, motor vehicle accessories, bicycles and 
sporting goods, toys, recreational vehicles, pleasure craft 
(recreational boats), extruded aluminum structural components, railroad 
cars, heavier vehicles, lawn and garden equipment, business machines, 
laboratory and medical equipment, electronic equipment, steel drums, 
metal pipes, and numerous other industrial and household products.
    The pleasure craft coating category does not include coatings that 
are a part of other product categories listed under Section 183(e) of 
the CAA for which CTGs have been published or included in other CTGs. 
For pleasure craft surface coatings, EPA took into account California 
regulations when developing the 2008 MMPP CTG. California was the only 
state at that time with regulations governing VOC emissions from 
pleasure craft surface coatings. After EPA finalized the 2008 MMPP CTG, 
the pleasure craft coatings industry asserted to EPA that three of the 
VOC emission limits in the CTG were too low considering the performance 
requirements of the pleasure craft coatings and that the VOC emission 
limits recommended did not represent RACT for the National pleasure 
craft coatings industry. On September 14, 2009, EPA was contacted by 
the pleasure craft coatings industry to reconsider some of the VOC 
emission limits recommended in the final 2008 MMPP CTG. In response, 
EPA issued a memorandum on June 1, 2010, entitled ``Control Technique 
Guidelines for Miscellaneous Metal and Plastic Part Coatings--Industry 
Request for Reconsideration,'' recommending that the pleasure craft 
industry work with state agencies during their RACT rule development 
process to assess what is reasonable for the specific sources 
regulated. EPA has stated that states can use the recommendations from 
the MMPP CTG to form their own determinations as to what constitutes 
RACT for pleasure craft coating operations. CTGs impose no legally 
binding requirements on any entity, including pleasure craft coating 
facilities. As stated in the memorandum, EPA will evaluate state-
developed RACT rules and determine whether the submitted rules meet the 
RACT requirements of the CAA.

II. Summary of SIP Revision and EPA Analysis

    On November 18, 2016, PADEP submitted a SIP revision which adopted 
the recommendations contained in the 2008 MMPP CTG with respect to 
sources in the miscellaneous metal products coatings and plastic parts 
coatings product categories. For the pleasure craft coating industry, 
after evaluating what is reasonable for this source category, PADEP 
determined that three VOC content limits in the CTG should be revised 
from the limits in the CTG to represent RACT for the pleasure craft 
coating industry. This is based on EPA's memorandum that the pleasure 
craft industry should work with state agencies during their RACT rule 
development process to assess what is reasonable for the specific 
sources regulated.
    The SIP revision includes an amendment to 25 Pa. Code Chapter 129--
(relating to standards for sources) as follows: (1) Amended section 
129.51(a)--(relating to general) in order

[[Page 39602]]

to extend applicability; (2) added section 129.52d--``Control of VOC 
emissions from miscellaneous metal parts surface coating processes, 
miscellaneous plastic parts surface coating processes and pleasure 
craft surface coatings,'' in order to regulate VOC emissions from these 
three categories; (3) amended section 129.52(g)--(relating to surface 
coating processes) in order to clarify record keeping and reporting 
requirements; (4) added section 129.52 subsection (k) in order to 
clarify the applicability of the requirements of section 129.52, Table 
I, Category 10 in 25 Pa. Code Chapter 129; (5) amended section 129.67 
(relating to graphic arts systems) in order to extend applicability; 
and (6) amended section 129.75 (relating to mobile equipment repair and 
refinishing) in order to specify exceptions for those who apply surface 
coating to mobile equipment already subject to requirements of sections 
129.52 and 129.52d. More detailed information on these provisions as 
well as a detailed summary of EPA's review and rationale for approving 
these SIP revisions can be found in the Technical Support Document 
(TSD) for this action, which is available on line at 
www.regulations.gov, Docket number EPA-R03-OAR-2017-0437.
    After evaluating the SIP revision submittal, EPA concluded that it 
meets CAA requirements under sections 110, 172(c)(1), 182(b)(2)(A), and 
184(b)(1) by adopting EPA's CTG and continuing to address and minimize 
VOC emissions in the Commonwealth of Pennsylvania, as discussed in more 
detail in EPA's TSD for this rulemaking action. PADEP is adopting 
without change most of the requirements recommended by the MMPP CTG but 
adopting the pleasure craft industry recommendations for the following 
three coating categories: Antifouling Sealer/Tiecoat; Other Substrate 
Antifoulant; and Extreme High Gloss. For these three categories, the 
Commonwealth of Pennsylvania reviewed industry data and determined that 
for the purpose of functionality, cost, and VOC emissions, the 
alternative limits adopted for these three coating categories 
constitute RACT. EPA concludes that Pennsylvania's approach is 
consistent with the guidance memorandum entitled, ``Control Technique 
Guidelines for Miscellaneous Metal and Plastic Part Coatings--Industry 
Request for Reconsideration,'' and therefore, concludes that these 
regulations reflect RACT given costs and VOC emissions. The revised VOC 
content limits for the pleasure craft surface coatings proposed by 
PADEP are expected to have a de minimis impact on the amount of VOC 
emission reductions from the implementation of the revised VOC limits 
due to having no facilities with the potential to emit VOC emissions 
for pleasure craft surface coatings.
    EPA notes that under 25 Pa. Code Sec. Sec.  129.52d, PADEP is 
allowing the provisions of 25 Pa. Code Sec.  129.52d to supersede the 
requirements of a RACT permit previously issued under 25 Pa. Code 
Sec. Sec.  129.91-129.95 if the permit was issued prior to January 1, 
2017, to the owner or operator of a source subject to section 
129.52d(a), except to the extent the RACT permit contains more 
stringent requirements. EPA further notes that the RACT permits issued 
under 25 Pa. Code Sec. Sec.  129.91-129.95 were issued for previous 
RACT determinations on a case-by-case basis; these permits were then 
submitted to EPA as source-specific SIP revisions and were previously 
acted on by EPA and would have been approved into the Pennsylvania SIP. 
If EPA approved those source-specific RACT determinations as meeting 
the requirements of RACT under the CAA, then the permits associated 
with those determinations were approved into the SIP as listed in 40 
CFR 52.2020(d). The requirements of the source-specific RACT 
determination which EPA approved into the Pennsylvania SIP remain 
applicable requirements for the specific source unless and until 
Pennsylvania seeks to remove the limits from the SIP in accordance with 
CAA section 110(l). To the extent that the provisions of 25 Pa. Code 
Sec.  129.52d are more stringent than those of a previous SIP-approved 
permit, PADEP will need to make a source-specific determination as to 
whether the requirements of the previous RACT permit apply, or those of 
Sec.  129.52d, and submit that determination to EPA as a SIP revision 
in order to remove the previously approved permit from the SIP. Until 
such a SIP revision is made, EPA cannot remove the source-specific 
permits from the SIP and EPA is not taking such action in this 
rulemaking. Thus, the requirements of a previously SIP-approved permit 
are not superseded under the SIP. In accordance with section 110 of the 
CAA including 110(a) and 110(l), EPA determines that approval of this 
PADEP SIP revision will not interfere with reasonable further progress, 
attainment of any NAAQS or any other applicable CAA requirements.
    On October 16, 2017 (82 FR 48034 and 82 FR 47988), EPA 
simultaneously published a notice of proposed rulemaking (NPR) and a 
direct final rule (DFR) for the Commonwealth of Pennsylvania approving 
the SIP revision. EPA received five adverse comments on the rulemaking 
and withdrew the DFR prior to the effective date of December 15, 2017.

III. Response to Comments

    During the comment period, EPA received several anonymous comments 
on the rulemaking. Of the comments, one comment generally discussed 
greenhouse gas from electric vehicles, a second comment generally 
discussed wildfires and wildland fire management policy, and a third 
comment generally discussed the Mercury and Air Toxics Standards. EPA 
believes these three comments are not germane to this rulemaking 
action, thus no further response is provided. The following is a 
summary of the comments pertinent to this rulemaking action and EPA's 
response to those comments.
    Comment #1: The first commenter stated that EPA did not address a 
March 28, 2017 Executive Order (E.O.) regarding the promotion of energy 
independence and economic growth.\2\
---------------------------------------------------------------------------

    \2\ Based on the comment, EPA assumes the E.O. in question is 
E.O. 13783, Promoting Energy Independence and Economic Growth, 
signed March 28, 2017.
---------------------------------------------------------------------------

    Response #1: EPA disagrees with the commenter's assertion that this 
rulemaking action required evaluation mandated under the E.O.. The E.O. 
in question pertains to reviewing existing regulations, orders, 
guidance documents, policies, and any other similar agency actions 
(collectively, agency actions) that potentially burden the development 
or use of domestically produced energy resources, with particular 
attention to oil, natural gas, coal, and nuclear energy. First, EPA 
does not believe this E.O. applies to this rulemaking action because, 
to the extent this rulemaking is considered an agency action under the 
E.O., this action was not an existing agency action as of March 28, 
2017, the date the E.O. was signed. Second, assuming arguendo, that 
this rulemaking action is considered an agency action under the E.O., 
this rulemaking action does not create a burden as that term is defined 
in the E.O.. As defined in the E.O., the term ``burden'' means, ``to 
unnecessarily obstruct, delay, curtail, or otherwise impose significant 
cost on the siting, permitting, production, utilization, transmission, 
or delivery of energy resources.'' This rulemaking action does not 
affect the siting, permitting, production, utilization, transmission, 
or delivery of energy resources because this action merely approves 
Pennsylvania's submission as meeting

[[Page 39603]]

certain necessary CTG requirements under the CAA, thus any required 
review under this E.O. is not applicable. Finally, EPA does not have 
discretion to disapprove the state's SIP submission if it meets the 
applicable CAA requirements. CAA section 110(k)(3) requires that EPA 
``shall'' approve the SIP submission ``as a whole'' if it meets the 
applicable requirements in the CAA. Pennsylvania's submission adopts 
RACT for sources identified in EPA's CTG, as required by CAA section 
184(b). Thus, considering the plain language of CAA section 110(k)(3), 
EPA cannot consider disapproving or requiring changes to a state's SIP 
submittal based on a particular E.O. or statutory reviews.
    Comment #2: The second commenter asserted that EPA should review 
its CTG and Alternative Control Technology (ACT) guidance documents to 
``make sure they aren't too costly.'' The commenter further asserted 
that VOC reductions in Pennsylvania are not needed and EPA should only 
require RACT reductions in areas with ``bad air.'' The commenter 
concluded by stating EPA should withdraw the rule in its entirety to 
enable economic growth and promote jobs.
    Response #2: EPA disagrees with the commenter that this rulemaking 
should be withdrawn and that EPA's CTGs and ACTs should be reviewed. 
The CTG at issue in this rulemaking was issued in 2008. This rulemaking 
action concerns only EPA's action approving Pennsylvania's SIP 
submission adopting the CTG requirements, and thus comments about the 
CTG itself are outside the scope of this action. In any case, EPA 
considered the cost of installing controls when developing the CTG and 
concluded, ``The recommended VOC emission rates described [in the CTG] 
reflect the control measures that are currently being implemented by 
these facilities. Consequently, there is no additional cost to 
implement the CTG recommendations for coatings.'' Further, the CTG went 
on to state the following for the work practices being recommended: 
``The CTG also recommends work practices for reducing VOC emissions 
from both coatings and cleaning materials. We believe that our work 
practice recommendations in the CTG will result in a net cost savings. 
Implementing work practices reduces the amount of coating and cleaning 
materials used by decreasing evaporation.'' Thus, EPA did consider cost 
when issuing this CTG in a prior rulemaking.
    EPA further disagrees with the commenter's assertion that VOC 
reductions are not needed in the entire Commonwealth of Pennsylvania, 
and disagrees that the state or EPA has any discretion to not implement 
those reductions. First, the commenter provided no evidence supporting 
a claim that VOC reductions are only needed in areas with ``bad air'' 
(EPA assumes this is a reference to nonattainment areas). Second, 
Congress has dictated through the CAA that VOC RACT is required to be 
implemented throughout the entire Commonwealth. CAA section 
182(b)(2)(A) requires that, for each ozone nonattainment area 
classified as Moderate or above, the area must revise their SIPs to 
include RACT for each category of VOC sources covered by CTG documents 
issued between November 15, 1990 and the date of attainment. CAA 
section 184(a) further establishes a single OTR which includes the 
entire Commonwealth of Pennsylvania, and section 184(b)(1)(B) requires 
all OTR states to submit SIPs implementing RACT with respect to all 
sources of VOC in the state that are covered by a CTG. Finally, 
Pennsylvania and EPA are not permitted to ignore statutory mandates for 
any policy reason, including to promote jobs or to enable economic 
growth. Thus, the requirements of the CAA require Pennsylvania to 
revise its SIP in order to implement VOC RACT for all CTGs issued, 
including the automobile and light-duty truck assembly coating 
category. As an OTR state, Pennsylvania is required to reduce VOCs by 
implementing RACT and CTGs.

IV. Final Action

    EPA is approving the Commonwealth of Pennsylvania's November 2016 
SIP revision submittal, which adopts EPA's CTG for miscellaneous metal 
parts surface coating, miscellaneous plastic parts surface coating, and 
pleasure craft surface coatings, and which makes other related 
administrative changes, because the revision meets the requirements of 
CAA sections 110, 172(c)(1), 182(b)(2)(A), and 184(b)(2).

V. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of the 
Pennsylvania rule discussed in section II of this preamble. EPA has 
made, and will continue to make, these materials generally available 
through http://www.regulations.gov and at the EPA Region III Office 
(please contact the person identified in the ``For Further Information 
Contact'' section of this preamble for more information). Therefore, 
these materials have been approved by EPA for inclusion in the SIP, 
have been incorporated by reference by EPA into that plan, are fully 
federally enforceable under sections 110 and 113 of the CAA as of the 
effective date of the final rulemaking of EPA's approval, and will be 
incorporated by reference in the next update to the SIP compilation.\3\

    \3\ 62 FR 27968 (May 22, 1997).

VI. Statutory and Executive Order Reviews

A. General Requirements

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement

[[Page 39604]]

Act of 1995 (15 U.S.C. 272 note) because application of those 
requirements would be inconsistent with the CAA; and
     does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.

B. Submission to Congress and the Comptroller General

    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. EPA will submit a report containing this action 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).

C. Petitions for Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by October 9, 2018. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. This action, which approves Pennsylvania's SIP revision 
adopting CTGs for miscellaneous metal parts surface coating, 
miscellaneous plastic parts surface coating, and pleasure craft surface 
coatings, as well as general administrative changes related to cleaning 
activities, may not be challenged later in proceedings to enforce its 
requirements (See section 307(b)(2)).
