More specifically, appendix C of the Ajo PM10 SIP includes PCC Section 17.16.125 and the related adoption materials. ADEQ submitted the Ajo PM10 SIP electronically on May 10, 2019, under cover of a transmittal letter dated May 8, 2019. Herein, EPA is taking final action on the PCC Section 17.16.125 portion of the Ajo PM10 SIP. The EPA is taking action on the rest of the Ajo PM10 Plan in a separate action (85 FR 34381 (June 4, 2020)). khammond on DSKJM1Z7X2PROD with RULES 2 ADEQ We proposed to approve these rules because we determined that they comply with the relevant CAA requirements. More specifically, with respect to MCAQD Rule 316, we previously determined that the rule implemented Best Available Control Measures for nonmetallic mineral processing within the Phoenix planning area, and we find that the 2018 amendments to the rule relax no control requirements and generally clarify and enhance the effectiveness of the rule. With respect to Pima County Code (PCC) Section 17.16.125, we find that the rule provides a means to ensure the permanence and enforceability of the fugitive dust controls that have already VerDate Sep<11>2014 15:52 Jul 14, 2020 Jkt 250001 been implemented in the Ajo PM10 planning area and that have brought the area into attainment of the Particulate Matter equal to or less than 10 microns in diameter (PM10) National Ambient Air Quality Standards (NAAQS). Our proposed action and related technical support documents (TSDs) contain more information on the rules and our evaluation. III. EPA Action II. Public Comments and EPA Responses IV. Incorporation by Reference The EPA’s proposed action provided a 30-day public comment period. During this period, we received no comments. In this rule, the EPA is finalizing regulatory text that includes incorporation by reference.

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.3 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 khammond on DSKJM1Z7X2PROD with RULES 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: • 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 3 62 FR 27968 (May 22, 1997). VerDate Sep<11>2014 15:52 Jul 14, 2020 Jkt 250001 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 PO 00000 Frm 00041 Fmt 4700 Sfmt 4700 42727 this action must be filed in the United States Court of Appeals for the appropriate circuit by September 14, 2020. 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).)

I. Proposed Action

    On May 1, 2020 (85 FR 25379), the EPA proposed to approve the 
following rules into the Arizona SIP.

----------------------------------------------------------------------------------------------------------------
                                                                                     Adopted/

                                                         and Slag Storage Area
                                                         within the Ajo PM
                                                         Planning Area.
----------------------------------------------------------------------------------------------------------------
\1\ Pima County Board of Supervisors adopted PCC Section 17.16.125 on January 22, 2019, with an effective date
  of February 21, 2019.
\2\ ADEQ submitted PCC Section 17.16.125 as part of a larger SIP revision submittal titled ``SIP Revision: Ajo
  PM10 Redesignation Request and Maintenance Plan (May 3, 2019)'' (herein referred to as the ``Ajo PM10 SIP'').
  More specifically, appendix C of the Ajo PM10 SIP includes PCC Section 17.16.125 and the related adoption
  materials. ADEQ submitted the Ajo PM10 SIP electronically on May 10, 2019, under cover of a transmittal letter
  dated May 8, 2019. Herein, EPA is taking final action on the PCC Section 17.16.125 portion of the Ajo PM10
  SIP. The EPA is taking action on the rest of the Ajo PM10 Plan in a separate action (85 FR 34381 (June 4,
  2020)).

    We proposed to approve these rules because we determined that they 
comply with the relevant CAA requirements. More specifically, with 
respect to MCAQD Rule 316, we previously determined that the rule 
implemented Best Available Control Measures for nonmetallic mineral 
processing within the Phoenix planning area, and we find that the 2018 
amendments to the rule relax no control requirements and generally 
clarify and enhance the effectiveness of the rule. With respect to Pima 
County Code (PCC) Section 17.16.125, we find that the rule provides a 
means to ensure the permanence and enforceability of the fugitive dust 
controls that have already been implemented in the Ajo PM10 
planning area and that have brought the area into attainment of the 
Particulate Matter equal to or less than 10 microns in diameter 
(PM10) National Ambient Air Quality Standards (NAAQS). Our 
proposed action and related technical support documents (TSDs) contain 
more information on the rules 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

    Pursuant to section 110(k)(3) of the CAA, and for the reasons 
discussed in detail in our proposed rule and TSDs, and summarized 
above, the EPA is fully approving MCAQD Rule 316, as submitted on 
November 19, 2018, and PCC Section 17.16.125, as submitted on May 10, 
2019, as revisions to 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

[[Page 42727]]

incorporation by reference of the MCAQD and PCDEQ rules 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.\3\ 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).

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

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:
     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 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 September 14, 2020. 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).)
