SUMMARY:

Illinois 60604. This facility is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding Federal holidays and facility closures due to COVID19. We recommend that you telephone Abigail Teener, Environmental Engineer, at 312 3537314 before visiting the Region 5 office.
FOR FURTHER INFORMATION CONTACT:
Abigail Teener, Environmental Engineer, Attainment Planning and Maintenance Section, Air Programs Branch AR18J, U.S. Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604, 312 3537314, teener.abigail@

On October 29, 2020, EPA proposed to approve the redesignation of the Southwest Indiana SO2 nonattainment area to attainment of the 2010 primary, health-based 1-hour SO2 NAAQS and to approve Indianas maintenance plan for the nonattainment area 85 FR 68533.
An explanation of the CAA
requirements, a detailed analysis of the revisions, and EPAs reasons for proposing approval were provided in the notice of proposed rulemaking and will not be restated here. The public comment period for this proposed rule ended on November 30, 2020. EPA
received no comments on the proposal.
II. Final Action In accordance with Indianas October 24, 2018 request and August 25, 2020
supplemental letter, EPA is redesignating the Southwest Indiana nonattainment area from nonattainment to attainment of the 2010 SO2 NAAQS.
EPA finds that Indiana has demonstrated that the area is attaining the 2010 SO2 NAAQS and that the improvement in air quality is due to permanent and enforceable SO2
emission reductions in the area. EPA is also approving Indianas maintenance plan, which is designed to ensure that the area will continue to maintain the SO2 NAAQS.
III. Statutory and Executive Order Reviews Under the CAA, redesignation of an area to attainment and the accompanying approval of a maintenance plan under section 107d3E are actions that affect the status of a geographical area and do not impose any additional regulatory requirements on sources beyond those imposed by state law. A redesignation to attainment does not in and of itself create any new requirements, but rather

results in the applicability of requirements contained in the CAA for areas that have been redesignated to attainment. Moreover, 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. 7410k; 40 CFR 52.02a.
Thus, in reviewing SIP submissions, EPAs 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. 1044;
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 12d 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
