SUMMARY: The Environmental Protection Agency (EPA) is reopening the 
comment period for a proposed revision to the Michigan State 
Implementation Plan (SIP) published September 18, 2020. Sierra Club 
requested additional time to provide comments; therefore, EPA is 
reopening the comment period for 28 days from the close of the previous 
comment period.

DATES: The comment period for the proposed rule published on September 
18, 2020 (85 FR 58315), is reopened. Comments must be received on or 
before November 16, 2020.

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 
(SO2) national ambient air quality standard (NAAQS) for the 
Detroit SO2 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.

Regional Administrator, Region 5.
