EPA approves Michigan's ozone air quality plan for Detroit area
Official: Air Plan Approval; Michigan; Determination of Attainment by the Attainment Date for the 2015 Ozone Standards
Reading: The EPA approval maintains the existing 2015 ozone NAAQS by confirming the Detroit area met it, rather than advancing or weakening the standard itself.
The approval is based on Michigan's request submitted in February 2026 and the EPA's agreement in March 2026.
In clear language
The EPA is proposing to approve Michigan's claim that the Detroit area met federal ozone pollution standards by the deadline, based on exceptional circumstances that excused some pollution. This determination would fulfill a federal requirement to verify whether the Detroit region achieved the Clean Air Act's 2015 ozone goals. The approval is based on Michigan's request submitted in February 2026 and the EPA's agreement in March 2026.
