(312)886-9401, *Arra.Sarah@epa.gov.* The EPA Region 5 office is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding Federal holidays and facility closures due to COVID 19. SUPPLEMENTARY INFORMATION: On September 18, 2020 (85 FR 58315), EPA proposed to partially approve and partially disapprove a revision to the Michigan SIP for attaining the 2010 1-hour primary sulfur dioxide (SO <sup>2</sup> ) national ambient air quality standard (NAAQS) for the Detroit SO <sup>2</sup> nonattainment area. This SIP revision includes Michigan's attainment demonstration and other elements required under the Clean Air Act (CAA). EPA proposed to approve the base year emissions inventory, and to affirm that the nonattainment new source review requirements for the area have been met. EPA proposed to disapprove the attainment demonstration, as well as the requirements for meeting reasonable further progress toward attainment of the NAAQS, reasonably available control measures and reasonably available control technology, and contingency measures. Finally, EPA proposed to disapprove the plan's control measures for two facilities as not demonstrating attainment, and proposed to approve the enforceable control measures for two facilities as SIP strengthening. The comment period closed on October 19, 2020. On October 9, 2020, EPA received a request from the Sierra Club to extend the comment period for four weeks from the end of the comment period. Dated: November 2, 2020. Kurt Thiede, Regional Administrator, Region 5. [FR Doc. 2020-24759 Filed 11-5-20; 8:45 am]
