Air Plan Approval; Michigan; Clean Data Determination for the Berrien, MI and Muskegon, MI Areas for the 2015 Ozone Standards- Facts included
- The EPA is determining under the Clean Air Act that the Berrien County and Muskegon County, Michigan nonattainment areas have attained the 2015 ozone NAAQS.
- The determination is based on complete, quality‑assured, and certified ambient air monitoring data for the 2023‑2025 design value period.
- The determination also relies on EGLE's exceptional events request submitted to the EPA on December 26, 2025, which the EPA concurred on January 12, 2026.
- As a result, the EPA is suspending the requirements for the areas to submit attainment demonstrations, RACM, RFP plans, contingency measures, and other SIP elements for as long as the areas continue to attain the 2015 ozone NAAQS.
