SUPPLEMENTARY INFORMATION:

Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA.

I. Background

This final rule addresses the April 6, 2021, SIP revisions submitted by the Wisconsin Department of Natural Resources (WDNR). This submittal includes revisions to the definitions in Chapter NR 400, to the minor construction permit program in Chapter NR 406, and to the operating permit program in Chapter NR 407. Specifically, Wisconsin is requesting to repeal NR 406.03(1e)(a), (b), and (j), NR 406.04(1f)(c) and (Note), NR 407.02(6)(a)3.(Note), NR 407.11(1)(e) and (3)(c), and NR 407.12(1)(b)(Note) and (e); and to amend and create NR 400.02(130), (136m), (136r), and (162), NR 406.02(6), NR 406.03(1e), (1m), and (2)(b), NR 406.04(1)(a)4m., (bm), (i), (m), (zg), (1f), (1k), (1q), (2)(h), (4)(a), (b), (e)3., (h), (j), and (7), NR 406.17(3)(d), NR 407.03(1)(intro.), (a), (bm), (1m), (2)(ba), (f) and (g), NR 407.05(2) and (6), NR 407.105(3)(b), and NR 407.15(5).

On December 6, 2021, EPA published a notice of proposed rulemaking (NPRM) proposing approval of Wisconsin's April 6, 2021, submittal (86 FR 68954). The specific details of these SIP revisions and the rationale for EPA's proposed approval are discussed in the NPRM and will not be restated here. The NPRM provided a 30-day public comment period which ended on January 5, 2022.

No comments were received on the proposed rule during the public comment process.

II. What action is EPA taking?

For the reasons set forth in the proposed rulemaking, EPA is approving the requested revisions to Wisconsin's SIP as submitted on April 6, 2021. These revisions were included in the certified Board Order AM-24-12b and published in the Wisconsin Administrative Register #777 on September 28, 2020.

III. Incorporation by Reference

In this rule, EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is finalizing the incorporation by reference of the Wisconsin Regulations described in the amendments to 40 CFR part 52 set forth below. EPA has made, and will continue to make, these documents generally available through www.regulations.gov, and at the EPA Region 5 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information).

Also in this document, as described in the proposed amendments to 40 CFR ( printed page 11958) part 52 set forth below, EPA is proposing to remove provisions of the EPA-Approved Wisconsin Regulations from the Wisconsin SIP, which is incorporated by reference in accordance with the requirements of 1 CFR part 51.

IV. Statutory and Executive Order Reviews

Under the Clean Air Act (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 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject toExecutive 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 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, underExecutive 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 Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by May 2, 2022. 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).)
