Abstract
The Environmental Protection Agency (EPA) is finding that the Detroit, Michigan area is attaining the 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS) and is acting in accordance with a request from the Michigan Department of Environment, Great Lakes, and Energy (EGLE) to redesignate the area to attainment for the 2010 SO<INF>2</INF> NAAQS, because the request meets the statutory requirements for redesignation under the Clean Air Act (CAA). The EPA is also approving Michigan's maintenance plan for the Detroit area. Michigan submitted the request for approval of the Detroit nonattainment area's redesignation and maintenance plan on May 5, 2025. The EPA approved Michigan's attainment plan for the Detroit area on May 19, 2025.
