SUPPLEMENTARY INFORMATION:

Throughout this document “we,” “us,” and “our” means the EPA.

I. Background

Under the Regional Haze Rule, states are required to submit progress reports that evaluate progress towards the reasonable progress goals for each mandatory Federal Class I area within the state and in each Class I area outside the state that may be affected by emissions from within the state.^[1] In addition, the provisions also require states to submit, at the same time as the progress report, a determination of the adequacy of the state's existing regional haze plan. The first progress report must be in the form of a SIP revision and is due 5 years after submittal of the initial regional haze SIP.

On November 28, 2017, Wyoming submitted a Progress Report SIP revision which: (1) Detailed the progress made toward achieving progress for improving visibility at Class I areas,^[2] and (2) declared a determination of adequacy of the State's regional haze plan to meet reasonable progress goals.

On April 17, 2020, the EPA published a proposed rulemaking titled “Approval and Promulgation of Implementation Plans; Wyoming; Regional Haze 5-Year Progress Report State Implementation Plan” proposing to approve Wyoming's Progress Report SIP revision.^[3] The rationale for the EPA's proposed action is explained in the proposed rulemaking and will not be restated here. The EPA is finalizing its proposed approval of the Progress Report as meeting the applicable regional haze requirements set forth in 40 CFR 51.309(d)(10).

II. Response to Comments

We did not receive any comments on our proposed rulemaking during the public comment period.

III. Final Action

The EPA is finalizing approval of Wyoming's November 28, 2017, Regional Haze Progress Report as meeting the applicable regional haze requirements set forth in 40 CFR 51.309(d)(10).

IV. 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);
• Is not anExecutive 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, 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 CAA; 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 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 August 25, 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)).

For the reasons set forth in the preamble, the EPA amends 40 CFR part 52 as follows:

1. The authority citation for part 52 continues to read as follows:

Authority: 42 U.S.C. 7401 et seq.

2. In § 52.2620, the table in paragraph (e) is amended by revising the entry “(32) XXXII” to read as follows:

85 FR 38325
