Michigan Regional Haze Plan Approved
The EPA approved Michigan’s Regional Haze State Implementation Plan (SIP) revision that Michigan submitted on August 23, 2021 and supplemented on July 24, 2025, finding it meets requirements under the Clean Air Act (sections 110 and 169A) and EPA’s Regional Haze Rule for the program’s second implementation period. The plan requires periodic long-term strategies to make reasonable progress toward preventing and remedying human-caused visibility impairment in mandatory Class I Federal areas. If you live in Michigan near a Class I Federal area, this approval means the state plan is in place to address haze and protect visibility there.
