AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

The Environmental Protection Agency (EPA) is finalizing approval of a revision to the Wisconsin State Implementation Plan (SIP) to meet the base year emissions inventory, reasonable further progress (RFP), RFP contingency measure, nitrogen oxides (NO_X) reasonably available control technology (RACT), and motor vehicle inspection and maintenance (I/M) requirements of the Clean Air Act (CAA) for the Wisconsin portion of the Chicago-Naperville, Illinois-Indiana-Wisconsin nonattainment area (Chicago area) for the 2008 ozone National Ambient Air Quality Standards (NAAQS or standards). EPA is also finalizing approval of the 2017 and 2018 transportation conformity motor vehicle emissions budgets (MVEBs) for the Wisconsin portion of the Chicago area for the 2008 ozone NAAQS. EPA proposed approval of these attainment planning elements on August 16, 2018, and received no adverse comments germane to this action. Therefore, EPA is finalizing approval of this SIP revision pursuant to section 110 and part D of the CAA and EPA's regulations because it satisfies the emission inventory, RFP, RFP contingency measure, NO_X RACT, I/M, and transportation conformity requirements for the Wisconsin portion of the Chicago area, which is classified as moderate nonattainment for the 2008 ozone NAAQS.

DATES:

This final rule is effective on March 15, 2019.

I. What is the background for this action?

A. Background on the 2008 Ozone NAAQS

On March 27, 2008, EPA promulgated a revised 8-hour ozone NAAQS of 0.075 parts per million (ppm).^[1] Promulgation of a revised NAAQS triggers a requirement for EPA to designate areas of the country as nonattainment, attainment, or unclassifiable for the standards. For the ozone NAAQS, this also involves classifying any nonattainment areas at the time of designation.^[2] Ozone nonattainment areas are classified based on the severity of their ozone levels (as determined based on the area's “design value,” which represents air quality in the area for the most recent three years). The classifications for ozone nonattainment areas are marginal, moderate, serious, severe, and extreme.^[3]

Areas that EPA designates nonattainment for the ozone NAAQS are subject to certain requirements, including the general nonattainment area planning requirements of CAA section 172 and the ozone-specific nonattainment planning requirements of CAA section 182. Ozone nonattainment areas in the lower classification levels have fewer and/or less stringent mandatory air quality planning and control requirements than those in higher classifications. For marginal areas, a state is required to submit a baseline emissions inventory, adopt provisions into the SIP requiring emissions statements from stationary sources in the area, and implement a nonattainment new source review (NSR) program for the relevant ozone NAAQS.^[4] For moderate areas, a state needs to comply with the marginal area requirements, plus additional moderate area requirements, including the requirement to submit a modeled demonstration that the area will attain the NAAQS as expeditiously as practicable but no later than six years after designation, the requirement to submit an RFP plan, the requirement to adopt and implement certain emissions controls, such as RACT and I/M, and the requirement for greater emissions offsets for new or modified major stationary sources under the state's nonattainment NSR program.^[5]

B. Background on the Chicago 2008 Ozone Nonattainment Area

On June 11, 2012,^[6] EPA designated the Chicago area as a marginal nonattainment area for the 2008 ozone NAAQS. The Chicago area includes Cook, DuPage, Kane, Lake, McHenry, and Will Counties and part of Grundy and Kendall Counties in Illinois; Lake and Porter Counties in Indiana; and the eastern portion of Kenosha County in Wisconsin. On May 4, 2016,^[7] pursuant to section 181(b)(2) of the CAA, EPA determined that the Chicago area failed to attain the 2008 ozone NAAQS by the July 20, 2015, marginal area attainment deadline and thus reclassified the area from marginal to moderate nonattainment. In that action, EPA established January 1, 2017, as the due date for all moderate area nonattainment plan SIP requirements applicable to newly reclassified areas.

II. What action is EPA taking?

As explained in the proposed rulemaking,^[8] EPA is approving revisions to Wisconsin's SIP pursuant to section 110 and part D of the CAA and EPA's regulations. Wisconsin's April 17, 2017, submission and January 23, 2018, supplement along with a prior submission made on August 15, 2016, satisfy the emission inventory, RFP, RFP contingency measure, NO_X RACT, emissions statement, I/M, and transportation conformity requirements for the Wisconsin portion of the Chicago area for the 2008 ozone NAAQS.

III. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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 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 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 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, 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 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 April 15, 2019. 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).)
