40 CFR Part 52

[EPA-R09-OAR-2021-0369; FRL-8996-02-R9]

Air Plan Approval; Arizona; Maricopa County Air Quality 
Department

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to approve revisions to the Maricopa County Air Quality 
Department's (MCAQD) Rule 510 as part of the Arizona State 
Implementation Plan (SIP). These rule revisions concern updates to the 
maximum levels of ambient air pollution for the protection of public 
health and welfare. We are finalizing our proposed approval of this 
rule to regulate ambient air emissions under the Clean Air Act (CAA or 
the Act).

DATES: This rule will be effective on November 3, 2021.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R09-OAR-2021-0369. All documents in the docket are

I. Proposed Action

    On June 23, 2021 (86 FR 32848), the EPA proposed to approve the 
following rule into the Arizona SIP:

----------------------------------------------------------------------------------------------------------------
             Local agency                  Rule No.            Rule title             Amended        Submitted
----------------------------------------------------------------------------------------------------------------
MCAQD.................................             510  Air Quality Standards...      12/11/2019      12/20/2019
----------------------------------------------------------------------------------------------------------------

    We proposed to approve this rule because we determined that it 
complies with the relevant CAA requirements. Our proposed action 
contains more information on the rule and our evaluation.

II. Public Comments and EPA Responses

    The EPA's proposed action provided a 30-day public comment period. 
During this period, we received no comments.

III. EPA Action

    No comments were submitted. Therefore, as authorized in section 
110(k)(3) of the Act, the EPA is fully approving this rule into the 
Arizona SIP. The December 11, 2019 version of Rule 510 will replace the 
previously approved version of this rule in the Arizona SIP.

IV. Incorporation by Reference

    In this rule, the EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, the EPA is finalizing the incorporation by reference of the MCAQD 
rule described in the amendments to 40 CFR part 52 set forth below. 
Therefore, these materials have been approved by the EPA for inclusion 
in the SIP, have been incorporated by reference by the 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 the EPA's 
approval, and will be incorporated by reference in the next update to 
the SIP compilation.\1\ The EPA has made, and will continue to make, 
these documents available through 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).

V. 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 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:

[[Page 54629]]

     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, 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 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).
    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 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 December 3, 2021. 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 may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2).)
