VII. Statutory and Executive Order Reviews 

I. What action is EPA taking? 

EPA is approving Maine’s Chapter 

162, ‘‘Fiberglass Boat Manufacturing 

Materials,’’ submitted on July 1, 2014, to 

address EPA’s Control Techniques 

Guidelines (CTG) for Fiberglass Boat 

Manufacturing Materials (EPA–453/R– 

08–004, September 2008). EPA is also 

approving Maine’s revised Chapter 129, 

‘‘Surface Coating Facilities,’’ submitted 

on August 18, 2015, to address EPA’s 

CTG for Miscellaneous Metal and 

Plastic Parts Coatings (EPA–453/R–08– 

003, September 2008). These two Maine 

regulations implement RACT for the 

applicable facility operations. Lastly, 

EPA is approving Maine’s negative 

declarations for two CTGs, Automobile 

and Light-Duty Truck Assembly 

Coatings (EPA–453/R–08–006, 

September 2008) and Large Appliance 

Coatings (EPA–453/R–07–004, 

September 2007), which were submitted 

on April 23, 2013. 

II. What is the background for this 

action? 

Maine is part of the Ozone Transport 

Region (OTR) under Section 184(a) of 

the CAA. Sections 182(b)(2) and 184 of 

the CAA compel states with moderate 

and above ozone nonattainment areas, 

as well as areas in the OTR, 

respectively, to submit a SIP revision 

requiring the implementation of RACT 

for sources covered by a CTG and for all 

major sources. A CTG is a document 

issued by EPA which establishes a 

‘‘presumptive norm’’ for RACT for a 

specific VOC source category. 


sradovich on DSK3TPTVN1PROD with RULES
Federal Register / Vol. 81, No. 102 / Thursday, May 26, 2016 / Rules and Regulations 33395 

On October 9, 2007, EPA issued three 

CTGs, including the CTG for Large 

Appliance Coatings, which states were 

required to address by October 9, 2008 

(72 FR 57215). Then on October 7, 2008, 

EPA issued four CTGs including 

Miscellaneous Metal and Plastic Parts 

Coatings, Fiberglass Boat Manufacturing 

Materials, and Automobile and LightDuty Truck Assembly Coatings, which 

states were required to address by 

October 7, 2009 (73 FR 58841). 

III. What is included in Maine’s 

submittals? 

On April 23, 2013, Maine submitted 

a SIP revision to EPA containing 

negative declarations for two CTG 

source categories: Automobile and 

Light-Duty Truck Assembly Coatings 

and Large Appliance Coatings. Negative 

declarations include a statement that no 

sources subject to the requirement in 

question are located in the state; thus 

the state need not adopt a regulation 

based on a CTG that otherwise would 

apply to such sources. Then on July 1, 

2014, Maine submitted a SIP revision to 

EPA containing a new regulation, 

Maine’s Chapter 162, ‘‘Fiberglass Boat 

Manufacturing Materials,’’ to address 

the CTG of the same name. Lastly, on 

August 18, 2015, Maine submitted 

revised Chapter 129, ‘‘Surface Coating 

Facilities,’’ to address EPA’s 

Miscellaneous Metal and Plastic Parts 

Coatings CTG. 

IV. EPA’s Evaluation of Maine’s 

Submittals 

Maine’s new Chapter 162, ‘‘Fiberglass 

Boat Manufacturing Materials,’’ is 

consistent with the recommendations 

for RACT found in EPA’s CTG for 

Fiberglass Boat Manufacturing 

Materials. This new regulation is 

effective on July 30, 2013, and applies 

to fiberglass boat manufacturing 

operations that have, before controls, 

combined actual emissions of 5,400 

pounds of VOC or more, per rolling 12- 

month period, from the use of gel coats, 

resins, and materials used to clean 

application equipment. Applicable 

facilities for which construction 

commenced prior to the effective date of 

the rule, must comply within 36 months 

after the effective date of the rule or 

upon initial startup, whichever is later, 

and facilities for which construction 

commenced on or after the effective date 

of the rule must comply upon their 

initial startup. Specifically, the rule 

applies to facilities that manufacture 

hulls or decks of boats from fiberglass 

but not to facilities that solely 

manufacture parts of boats such as 

hatches, seats, or lockers. Sources 

subject to the rule must meet specific 

VOC content limits for resin and gel 

coat operations such as open molding, 

mixing and cleaning application 

equipment. Facilities may meet these 

limits by implementing one of the 

following prescribed techniques: Use of 

low-VOC content materials; averaging 

the VOC content of materials to meet 

low-VOC content standards; and/or the 

installation and operation of pollution 

control devices. Maine’s rule has the 

same VOC content limits as the CTG 

and also includes the appropriate 

recordkeeping, reporting, and testing 

requirements to ensure these emission 

limits are enforceable. The new 

regulation also specifies work practices 

to reduce VOC emissions during the 

application, storage, mixing, and 

conveyance of coatings, resins, and 

cleaning materials. 

Maine’s Chapter 129, ‘‘Surface 

Coating Facilities,’’ was previously 

approved by EPA on May 22, 2012 (77 

FR 30216). The revised rule has been 

expanded to include the coating of 

plastic parts and products and to 

include additional coating categories for 

the coating of miscellaneous metal parts 

and products. The amendments provide 

for five major surface coating categories 

with numerous subcategories in each to 

further identify which coatings are 

subject to a specific VOC emission limit. 

The emissions limits may be achieved 

by using one or more of three 

compliance methods: Low solvent 

content coating technology; dailyweighted averaging of emission 

limitations; and installation and 

operation of an add-on air pollution 

control device with 95% capture and 

control efficiency. Maine’s Chapter 129 

also includes the appropriate 

recordkeeping, reporting, and testing 

requirements to ensure these emission 

limits are enforceable. 

The new coating limits generally 

follow the recommendations in EPA’s 

CTG for Miscellaneous Metal and 

Plastic Parts Coating, with the exception 

of three coating categories which, as 

explained below, does not render the 

rule as a whole less stringent than the 

rule previously approved by EPA into 

the Maine SIP. Maine adopted higher 

coating limits for Pleasure Craft Surface 

Coating than the CTG for Extreme High 

Gloss Topcoat, Other Substrate 

Antifoulant Coating, and Antifouling 

Sealer/Tie Coating. For these three 

categories, Maine reviewed industry 

data and determined that for purpose of 

functionality, cost, and VOC emissions, 

the alternative limits adopted for these 

three coating categories constitute 

RACT. Maine’s approach is consistent 

with the EPA guidance memorandum, 

entitled ‘‘Control Technique Guidelines 

for Miscellaneous Metal and Plastic Part 

Coatings—Industry Request for 

Reconsideration,’’ from Stephen Page to 

Air Branch Chiefs, Regions I–X, dated 

June 1, 2010. Although some of the 

miscellaneous metal parts and products 

specialty coatings limits in Maine’s 

revised Chapter 129 are higher than the 

limits that had been previously 

approved into the Maine SIP, the more 

frequently used General One 

Component and General Multi 

Component coating limits for metal 

parts are lower than the previous SIPapproved general category limit for 

metal parts referred to as ‘‘All Other 

Coatings.’’ In addition, the revised rule’s 

applicability is much broader. Thus, the 

revised rule satisfies the anti-back 

sliding requirements in Section 110(l) of 

the CAA because, the rule as whole will 

achieve an equal or greater amount of 

VOC reductions as compared to the rule 

previously approved into the SIP. This 

analysis is also consistent with the EPA 

guidance memorandum entitled 

‘‘Approving SIP Revisions Addressing 

VOC RACT Requirements for Certain 

Coating Categories,’’ dated March 17, 

2011. 

Maine also submitted negative 

declarations for two CTGs: Automobile 

and Light-Duty Truck Assembly 

Coatings and Large Appliance Coatings. 

Maine staff reviewed the inventory of 

sources for facilities with North 

American Industrial Classification 

System (NAICS) codes that correspond 

to these source categories, interviewed 

its field and compliance staff, and 

searched telephone and business 

directories to determine if any sources 

meeting the applicability requirements 

of these two CTGs are located in Maine. 

After thoroughly reviewing all available 

information, Maine determined that 

there were no sources meeting the 

applicability thresholds for these two 

source categories. 

As discussed above, Maine’s new 

Chapter 162 and revised Chapter 129 are 

consistent with the relevant CTGs with 

the exception of certain limited 

provisions that do not result in greater 

emissions of VOCs than otherwise 

would be the case. Therefore, EPA has 

concluded that Maine has met the CAA 

RACT requirement for the Fiberglass 

Boat Manufacturing Materials and the 

Miscellaneous Metal and Plastic Parts 

Coatings CTG source categories. In 

addition, Maine’s method for arriving at 

the negative declarations for EPA’s 

Automobile and Light-Duty Truck 

Assembly Coatings CTG and EPA’s 

Large Appliance Coatings CTG is 

reasonable and EPA believes that the 

declarations are accurate. Therefore, 

EPA has concluded that Maine has also 


sradovich on DSK3TPTVN1PROD with RULES
33396 Federal Register / Vol. 81, No. 102 / Thursday, May 26, 2016 / Rules and Regulations 

met the CAA RACT requirement for 

these two CTG source categories. 

V. Final Action 

EPA is approving, and incorporating 

into the Maine SIP, Maine’s new 

Chapter 162, ‘‘Fiberglass Boat 

Manufacturing Materials,’’ and Maine’s 

revised Chapter 129, ‘‘Surface Coating 

Facilities,’’ as meeting RACT for the 

Fiberglass Boat Manufacturing and the 

Miscellaneous Metal and Plastic Parts 

Coatings CTG source categories, 

respectively. Additionally, EPA is 

approving Maine’s negative declarations 

for two CTG source categories: 

Automobile and Light-duty Truck 

Assembly Coatings and Large Appliance 

Coatings. 

The EPA is publishing this action 

without prior proposal because the 

Agency views this as a noncontroversial 

amendment and anticipates no adverse 

comments. However, in the proposed 

rules section of this Federal Register 

publication, EPA is publishing a 

separate document that will serve as the 

proposal to approve the SIP revision 

should relevant adverse comments be 

filed. This rule will be effective July 25, 

2016 without further notice unless the 

Agency receives relevant adverse 

comments by June 27, 2016. 

If the EPA receives such comments, 

then EPA will publish a notice 

withdrawing the final rule and 

informing the public that the rule will 

not take effect. All public comments 

received will then be addressed in a 

subsequent final rule based on the 

proposed rule. The EPA will not 

institute a second comment period on 

the proposed rule. All parties interested 

in commenting on the proposed rule 

should do so at this time. If no such 

comments are received, the public is 

advised that this rule will be effective 

on July 25, 2016 and no further action 

will be taken on the proposed rule. 

Please note that if EPA receives adverse 

comment on an amendment, paragraph, 

or section of this rule and if that 

provision may be severed from the 

remainder of the rule, EPA may adopt 

as final those provisions of the rule that 

are not the subject of an adverse 

comment. 

VI. Incorporation by Reference 

In this rule, the EPA is finalizing 

regulatory text that includes 

incorporation by reference. In 

accordance with the requirements of 1 

CFR 51.5, the EPA is finalizing the 

incorporation by reference of the Maine 

DEP regulations described in the 

amendments to 40 CFR part 52 set forth 

below. The EPA has made, and will 

continue to make, these documents 

generally available electronically 

through http://www.regulations.gov. 

VII. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, the 

Administrator is required to approve a 

SIP submission that complies with the 

provisions of the Act 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 Clean Air Act. 

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); 

• 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 

Act of 1995 (15 U.S.C. 272 note) because 

application of those requirements would 

be inconsistent with the Clean Air Act; 

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, the SIP is not approved 

to apply on any Indian reservation land 

or in any other area where EPA or an 

Indian tribe has demonstrated that a 

tribe has jurisdiction. In those areas of 

Indian country, the rule does not have 

tribal implications and will not impose 

substantial direct costs on tribal 

governments or preempt tribal law as 

specified by Executive Order 13175 (65 

FR 67249, November 9, 2000). 

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). 

Under section 307(b)(1) of the Clean 

Air Act, petitions for judicial review of 

this action must be filed in the United 

States Court of Appeals for the 

appropriate circuit by July 25, 2016. 

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. Parties with 

objections to this direct final rule are 

encouraged to file a comment in 

response to the parallel notice of 

proposed rulemaking for this action 

published in the proposed rules section 

of today’s Federal Register, rather than 

file an immediate petition for judicial 

review of this direct final rule, so that 

EPA can withdraw this direct final rule 

and address the comment in the 

proposed rulemaking. This action may 

not be challenged later in proceedings to 

enforce its requirements. (See section 

307(b)(2).)
