Air Plan Approval; Arizona; Maricopa County Air Quality 
Management Department

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revisions to the Maricopa County Air Quality Department (MCAQD 
or ``County'') portions of the Arizona State Implementation Plan (SIP). 
These revisions concern the County's reasonably available control 
technology (RACT) demonstration for the aerospace coating category 
(``aerospace operations RACT certification'') and negative declarations 
for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS 
or ``standards'') in the portion of the Phoenix-Mesa ozone 
nonattainment areas regulated by the MCAQD, as well as a rule covering 
emissions of volatile organic compounds (VOCs) from surface coatings 
and industrial adhesives. We are proposing to approve the SIP revisions 
under the Clean Air Act (CAA or ``the Act''). We are taking comments on 
this proposal and plan to follow with a final action.

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

    On December 20, 2021, the submittal for the aerospace operations 
RACT certification was deemed by operation of law to meet the 
completeness criteria in 40 CFR part 51 Appendix V. On March 17, 2022, 
the submittals for the negative declarations and MCAQD Rule 336 were 
deemed by operation of law to meet the completeness criteria in 40 CFR 
part 51 Appendix V. The completeness criteria in 40 CFR part 51 
Appendix V must be met before formal EPA review.

B. Are there other versions of these documents?

    There are no previous versions of the aerospace operations RACT 
certification in the MCAQD portion of the Arizona SIP for the 2008 
Ozone NAAQS. ADEQ previously submitted a negative declaration for this 
RACT control techniques guideline (CTG) category, though the EPA 
disapproved the negative declaration on January 7, 2021 (86 FR 971).
    We conditionally approved an earlier version of Rule 336 and RACT 
demonstration for the Miscellaneous Metal and Plastic Parts Coating 
(MMPPC) CTG \1\ into the SIP on January 7, 2021 (86 FR 971). The MCAQD 
adopted revisions to the SIP-approved version and negative declarations 
for subcategories of the CTG on September 1, 2021, and ADEQ submitted 
them to us on September 17, 2021. In its submittal letter, ADEQ 
requested that, upon approval of the revised version of Rule 336, the 
EPA remove the old version of this rule from this SIP. If we take final 
action to approve the September 1, 2021 version of Rule 336, this 
version will replace the previously approved version of this rule in 
the SIP.

C. What is the purpose of the submitted documents?

    Emissions of VOCs contribute to the production of ground-level 
ozone, smog, and particulate matter (PM), which harm human health and 
the environment. Section 110(a) of the CAA requires states to submit 
regulations that control VOC emissions. Sections 182(b)(2) and (f) 
require that SIPs for ozone nonattainment areas classified as Moderate 
or above implement RACT for any source covered by a Control Techniques 
Guidelines (CTG) document and for any major source of VOCs or 
NOX. The MCAQD is subject to this requirement because it 
regulates the Maricopa County portion of the Phoenix-Mesa ozone 
nonattainment area that is currently classified as a Moderate 
nonattainment area for the 2008 8-hour ozone NAAQS. Therefore, the 
MCAQD must, at a minimum, adopt RACT-level controls for all sources 
covered by a CTG document and for all major non-CTG sources of VOCs or 
NOX within the ozone nonattainment area that it regulates. 
Any stationary source that emits or has the potential to emit at least 
100 tons per year (tpy) of VOCs or NOX is a major stationary 
source in a Moderate ozone nonattainment area (CAA section 182(b)(2), 
(f) and 302(j)).
    Section III.D of the preamble to the EPA's final rule to implement 
the 2008 ozone NAAQS \2\ discusses RACT requirements. It states in part 
that RACT SIPs must contain adopted RACT regulations, certifications 
where appropriate that existing provisions are RACT, and/or negative 
declarations that no sources in the nonattainment area are covered by a 
specific CTG.\3\ It also provides that states must submit appropriate 
supporting information for their RACT submissions as described in the 
EPA's implementation rule for the 1997 ozone NAAQS.\4\ On January 7, 
2021 (86 FR 971), the EPA partially disapproved MCAQD's negative 
declarations for RACT categories associated with the following CTG 
categories:

Coating Operations at Aerospace Manufacturing and Rework Operations'' 
(EPA-453/R-97-004),
     ``Control Techniques Guidelines for Miscellaneous 
Industrial Adhesives'' (EPA-453/R-08-005).
    The submitted aerospace operations RACT certification provides 
MCAQD's analyses of its compliance with the CAA section 182 RACT 
requirements for the 2008 8-hour ozone NAAQS. It addresses the CTG RACT 
requirements in the ``National Emission Standards for Hazardous Air 
Pollutants for Source Categories: Aerospace Manufacturing and Rework'' 
and ``Control of Volatile Organic Compound Emissions from Coating 
Operations at Aerospace Manufacturing and Rework Operations'' CTGs.
    MCAQD also adopted and submitted for SIP approval the following 
rule and negative declarations which address the CTG RACT requirements 
for the CTG

categories for Miscellaneous Industrial Adhesives and MMPPC.
    Rule 336 is a local control measure that establishes VOC content 
limits for surface coating operations and industrial adhesive 
application in the Maricopa County portion of the Phoenix-Mesa 8-hour 
ozone nonattainment area. On January 7, 2021 (86 FR 971), the EPA 
conditionally approved MCAQD Rule 336 and the RACT certification 
associated with the rule and the CTG categories. The conditional 
approval was based on a commitment from the State to submit a revised 
rule that would correct deficiencies in Rule 336 and establish RACT-
level controls for sources covered by the CTG source categories:

Stationary Sources--Volume II: Surface Coating of Cans, Coils, Paper, 
Fabrics, Automobiles, and Light-Duty Trucks'' EPA-450/2-77-008, May 
1977 (cans and fabrics portions only \5\),
---------------------------------------------------------------------------

    \5\ Note that on January 7, 2021 (86 FR 971) EPA finalized 
approval of negative declaration for the other categories covered by 
this CTG: surface coating of coils, paper, automobiles, and light-
duty trucks.

    The Rule 336 submittal included negative declarations for three 
subcatgories under the 2008 MMPPC CTG:
     Business Machine Plastic Part Coatings (Table 4 of the 
2008 MMPPC CTG),
     Automotive/Transportation Plastic Part Coatings (Table 4 
of the 2008 MMPPC CTG),
     Motor Vehicle Materials (Table 6 of the 2008 MMPPC CTG).
    Revisions to Rule 336 and the negative declarations adopted on 
September 1, 2021, corrected the deficiencies. EPA's technical support 
document (TSD) has more information about the County's rule and the 
EPA's evaluations thereof.

II. The EPA's Evaluation and Action

A. How is the EPA evaluating the submitted documents?

    SIP rules must require RACT for each category of sources covered by 
a CTG document and for each major source of VOCs or NOX in 
ozone nonattainment areas classified as Moderate or above (CAA section 
182(b)(2)). The MCAQD regulates a Moderate ozone nonattainment area (40 
CFR 81.305) so MCAQD's rules must implement RACT.
    States should also submit for SIP approval negative declarations 
for those source categories for which they have not adopted RACT-level 
regulations (because they have no sources above the CTG-recommended 
applicability threshold) regardless of whether such negative 
declarations were made for an earlier SIP. To do so, the submittal 
should provide reasonable assurance that no sources subject to the CTG 
requirements currently exist in the portion of the ozone nonattainment 
area that is regulated by the MCAQD.
    The County's analysis must demonstrate that each major source of 
VOCs or NOX in the ozone nonattainment area is covered by a 
RACT-level rule. In addition, for each CTG source category, the County 
must either demonstrate that a RACT-level rule is in place or submit a 
negative declaration. Guidance and policy documents that we use to 
evaluate CAA section 182 RACT requirements include the following:
    1. ``State Implementation Plans; General Preamble for the 
Implementation of Title I of the Clean Air Act Amendments of 1990,'' 57 
FR 13498 (April 16, 1992); 57 FR 18070 (April 28, 1992).
    2. Memorandum dated May 18, 2006, from William T. Harnett, 
Director, Air Quality Policy Division, to Regional Air Division 
Directors, Subject: ``RACT Qs & As--Reasonably Available Control 
Technology (RACT): Questions and Answers.''
    3. ``Final Rule to Implement the 8-hour Ozone National Ambient Air 
Quality Standard--Phase 2,'' 70 FR 71612 (November 29, 2005).
    4. ``Implementation of the 2008 National Ambient Air Quality 
Standards for Ozone: State Implementation Plan Requirements,'' 80 FR 
12264 (March 6, 2015).
    Rules that are submitted for inclusion into the SIP must be 
enforceable (CAA section 110(a)(2)), must not interfere with applicable 
requirements concerning attainment and reasonable further progress or 
other CAA requirements (CAA section 110(l)), and must not modify 
certain SIP control requirements in nonattainment areas without 
ensuring equivalent or greater emissions reductions (CAA section 193).
    In addition to the documents listed above, guidance and policy 
documents that we use to evaluate enforceability, stringency, and 
revision/relaxation requirements include the following:

Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations,'' 
May 25, 1988 (``the Bluebook,'' revised January 11, 1990).

    11. ``Control Techniques Guidelines for Miscellaneous Industrial 
Adhesives'' (EPA-453/R-08-005, September 2008).

B. Do the documents meet the evaluation criteria?

    The submitted rule meets CAA requirements and is consistent with 
relevant guidance regarding enforceability, RACT, and SIP revisions. 
The TSD has more information on our evaluation. The submitted negative 
declarations describe how the MCAQD evaluated whether there were 
sources emitting VOCs in the CTG subcategories. After review of the 
emissions inventories list, we agree with the County's assessment 
determining the negative declarations are correct.
    The MCAQD's aerospace operations RACT certification constitutes the 
County's demonstration that the existing SIP-approved MCAQD Rule 348 
``Aerospace Manufacturing and Rework Operations'' satisfies CAA section 
182 RACT requirements for the 2008 8-hour ozone NAAQS for the CTG 
category

[[Page 47666]]

covered by the EPA CTG for Control of Volatile Organic Compound 
Emissions from Coating Operations at Aerospace and Manufacturing Rework 
(EPA-453/R-97-004). This conclusion is based on MCAQD's comparison of 
Rule 348 against the EPA CTG as well as other EPA SIP-approved rules 
for this category in California,\6\ Indiana,\7\ and Texas.\8\ The VOC 
limits for various categories in Rule 348 are either equally or more 
stringent than the CTG, as well as the Indiana and Texas rules. 
However, the California district rules are more stringent in 16 coating 
categories and less stringent than Rule 348 in 13 coating categories. 
Of the 16 coating categories where the California district rules had 
more stringent VOC limits, MCAQD surveyed affected sources and 
determined the VOC emissions from those categories were found to be 
less than 0.5% of each facility's total VOC emissions. Additionally, 
the County summarized where the rule was consistent with the CTG: VOC 
control and capture efficiency of at least 85% by weight is an 
alternative to limiting the VOC limits: solvent cleaning requirements; 
VOC containment and disposal; exemptions; and definitions. Based on 
these findings, the EPA concludes that the RACT demonstration satisfies 
CAA section 182 RACT requirements for the 2008 8-hour ozone NAAQS for 
the CTG category covered by the EPA CTG for Control of Volatile Organic 
Compound Emissions from Coating Operations at Aerospace and 
Manufacturing Rework (EPA-453/R-97-004).

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

C. Public Comment and Proposed Action

    As authorized in section 110(k)(3) of the Act, the EPA proposes to 
fully approve the submitted rule, negative declarations, and RACT 
demonstration because they fulfill all relevant requirements. In 
addition, we propose to convert the partial conditional approval of 
RACT demonstrations for the 2008 8-hour ozone NAAQS with respect to the 
VOC source categories covered by Rule 336 and the negative 
declarations, as found in 40 CFR 52.119 (c)(3), to full approval. We 
will accept comments from the public on this proposal until September 
6, 2022. If we take final action to approve the submitted rule and RACT 
demonstration, our final action would correct the deficiencies 
identified in our January 7, 2021 partial approval, partial 
disapproval, and partial conditional approval of parts of MCAQD's RACT 
SIP submittal for the 2008 8-hour ozone NAAQS (86 FR 971).

III. Incorporation by Reference

    In this rule, the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference MCAQD Rule 336, ``Surface Coating Operations and Industrial 
Adhesive Application Process,'' as described in Section I of this 
preamble. The EPA has made, and will continue to make, these materials 
available through https://www.regulations.gov and at the EPA Region IX 
Office (please contact the person identified in the FOR FURTHER 
INFORMATION CONTACT section of this preamble for more information).

IV. 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, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this proposed action merely proposes to approve state law 
as meeting federal requirements and does not impose additional 
requirements beyond those imposed by state law. For that reason, this 
proposed 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 the EPA with the discretionary authority 
to address disproportionate human health or environmental effects with 
practical, appropriate, 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 the 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).
