2021-17712. Air Plan Approval; Iowa; Infrastructure State Implementation Plan Requirements for the 2015 Ozone National Ambient Air Quality Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

The Environmental Protection Agency (EPA) is taking final action to approve certain elements of a State Implementation Plan (SIP) submission from the State of Iowa addressing the applicable requirements of section 110 of the Clean Air Act (CAA) for the 2015 Ozone (O₃) National Ambient Air Quality Standard (NAAQS). Section 110 requires that each state adopt and submit a SIP revision to support the implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by the EPA. These SIPs are commonly referred to as “infrastructure” SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA.

DATES:

This final rule is effective on September 22, 2021.

ADDRESSES:

I. Background

On June 29, 2021, the EPA proposed to approve Iowa's infrastructure SIP submission for the 2015 O₃ NAAQS in the Federal Register (86 FR 34175). The EPA solicited comments on the proposed approval of the infrastructure SIP submission and received no comments.

II. What is being addressed in this document?

The EPA is approving the infrastructure SIP submission received from the state on November 30, 2018 in accordance with section 110(a)(1) of the CAA. Specifically, the EPA is approving Iowa's SIP as meeting the following infrastructure elements of section 110(a)(2) of the CAA: (A) through (C), (D)(i)(II)—prevention of significant deterioration of air quality (prong 3) and protection of visibility (prong 4), (D)(ii), (E) through (H), and (J) through (M). Elements of section 110(a)(2)(D)(i)(I)—significant contribution to nonattainment (prong 1) and interfering with maintenance of the NAAQS (prong 2) will be addressed in a separate action.

Section 110(a)(2)(I) was discussed in the submission; however, the EPA does not expect infrastructure SIP submissions to address element (I). Section 110(a)(2)(I) requires states to meet the applicable SIP requirements of part D of the CAA relating to designated nonattainment areas. The specific part D submissions for designated nonattainment areas are subject to different submission schedules than those for section 110 infrastructure elements. The EPA will act on part D attainment plan SIP submissions through a separate rulemaking governed by the requirements for nonattainment areas, as described in part D.

A Technical Support Document (TSD) in the docket provides additional details of this action, including an analysis of how the SIP meets the applicable CAA section 110 requirements for infrastructure SIPs.

III. Have the requirements for approval of a SIP revision been met?

The State met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The EPA determined that the submission satisfied the completeness criteria of 40 CFR part 51, appendix V. The State provided a public comment period for this SIP revision from September 18, 2018 to October 19, 2018 and received two comments related to a request for more stringent ozone requirements and an increase in ozone monitors. The state provided an adequate response to these comments. In addition, as explained in more detail in the TSD which is part of this docket, the infrastructure SIP submission meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations. The public comment period on the EPA's proposed rule opened June 29, 2021, the date of its publication in the Federal Register and closed on July 29, 2021. During this period, the EPA received no comments.

IV. What action is the EPA taking?

The EPA is approving elements of the November 30, 2018, submission from the State of Iowa addressing the infrastructure elements for the 2015 O₃ NAAQS. Specifically, the EPA is approving Iowa's SIP as meeting the following infrastructure elements of section 110(a)(2): (A) through (C), (D)(i)(II) prong 3 and prong 4, (D)(ii), (E) through (H), (J) through (M). The EPA intends to act on the elements of section 110(a)(2)(D)(i)(I)—prong 1 and prong 2 in a subsequent rulemaking. The EPA is not addressing Section 110(a)(2)(I) as it is the EPA's interpretation of the CAA that these elements do not need to be addressed in the context of an infrastructure SIP submission.

Based upon review of the State's infrastructure SIP submissions and relevant statutory and regulatory authorities and provisions referenced in those submissions or referenced in Iowa's SIP, the EPA finds that Iowa's SIP meets all applicable required elements of sections 110(a)(1) and (2) (except as otherwise noted) with respect to the 2015 O₃ NAAQS.

V. Statutory and Executive Order Reviews

Under the CAA, 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 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);
• 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 the National Technology Transfer and Advancement Act (NTTA) because this rulemaking does not involve technical standards; 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 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. 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 22, 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)).
