 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: Due to the receipt of an adverse comment on a direct final rule published on September 29, 2021, the Environmental Protection Agency (EPA) is revising its regulations approving elements of a State Implementation Plan revision submitted by the Illinois Environmental Protection Agency on September 29, 2017, May 16, 2019, and September 22, 2020. The submitted revisions were intended to address the infrastructure requirements of section 110 of the Clean Air Act for the 2012 annual fine particulate matter (PM2.5) and 2015 ozone National Ambient Air Quality Standards (NAAQS).
 DATES: This final rule is effective January 18, 2022.

SUPPLEMENTARY INFORMATION: EPA published a direct final rule on September 29, 2021 (86 FR 53872), approving elements of a State Implementation Plan (SIP) revision submitted by the State of Illinois regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2012 PM2.5
                     and 2015 ozone NAAQS and approving the infrastructure requirements related to Prevention of Significant Deterioration (PSD) for previous NAAQS. In the direct final rule, EPA stated that if adverse comments were received by October 29, 2021, the rule would be withdrawn and not take effect. On October 27, 2021, EPA received a comment. EPA believes this comment is adverse and, therefore, EPA is revising its regulations because EPA was unable to withdraw the direct final rule before it took effect. EPA will address the comment in a subsequent final action based upon the proposed action also published on September 29, 2021. 
                    *See*86 FR 53915. EPA will not institute a second comment period on this action. List of Subjects in 40 CFR Part 52 Environmental protection
