SUMMARY:

Pursuant to the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is approving as a revision to the Indiana State Implementation Plan (SIP), the State's plan for maintaining the 1997 ozone National Ambient Air Quality Standards (NAAQS) through the end of the second 10-year maintenance period. On June 20, 2019, the Indiana Department of Environmental Management submitted the State's plan for maintaining the 1997 ozone NAAQS for the Indianapolis, La Porte County, and South Bend-Elkhart areas and the Indiana portions of the Chicago-Gary-Lake County, IL-IN (Chicago), Cincinnati-Hamilton, OH-KY-IN (Cincinnati), and Louisville, KY-IN (Louisville) multi-state areas. EPA proposed to approve the submission on September 25, 2019, and received no comments. This action makes certain commitments related to maintenance of the 1997 ozone NAAQS in these areas federally enforceable as part of the Indiana SIP.

III. What action is EPA taking?

EPA is approving, as a revision to the Indiana SIP, the State's plan for maintaining the 1997 ozone NAAQS for the Indianapolis, La Porte County, and South Bend-Elkhart areas and the Indiana portions of the Chicago, Cincinnati, and Louisville areas through the end of the second 10-year maintenance period.

VI. 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 it is not a significant regulatory action 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 disproportionate human health or environmental effects with practical, appropriate, 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).
