SUPPLEMENTARY INFORMATION: On March 14, 2022 (87 FR 14210), EPA 
proposed to find that the Detroit, Michigan area is attaining the 2015 
primary and secondary ozone National Ambient Air Quality Standards 
(NAAQS), and to act in accordance with a request from the Michigan 
Department of Environment, Great Lakes, and Energy (EGLE) to 
redesignate the area to attainment for the 2015 ozone NAAQS because the 
request meets the statutory requirements for redesignation under the 
Clean Air Act. The Detroit area includes Livingston, Macomb, Monroe, 
Oakland, St. Clair, Washtenaw, and Wayne Counties. EGLE submitted this 
request on January 3, 2022. EPA also proposed to approve, as a revision 
to the Michigan State Implementation Plan, the State's plan for 
maintaining the 2015 ozone NAAQS through 2035 in the Detroit area. EPA 
also proposed to approve Michigan's 2025 and 2035 volatile organic 
compound and oxides of nitrogen motor vehicle emissions budgets 
(budgets) for the Detroit area and initiating the adequacy review 
process for these budgets. Finally, EPA also proposed to approve 
portions of separate December 18, 2020, submittals as meeting the 
applicable requirements for a base year emissions inventory and 
emissions statement program. On March 21, 2022, Sierra Club requested 
that EPA extend the comment period by 21 days, to allow Sierra Club 
additional time to ``review the basis for EPA's proposal and confer 
with local partners.'' In response, EPA is extending the comment period 
for 14 days. This extension provides additional time to Sierra Club and 
its local partners, while also allowing time for EPA and EGLE to plan 
for additional upcoming rulemakings that relate to EPA's findings on 
this proposed action.

Regional Administrator, Region 5.
