SUPPLEMENTARY INFORMATION:

On February 27, 2026 (91 FR 9793), the EPA proposed to approve revisions and additions to Michigan Air Pollution Control Rules (MAPCR) Parts 6 and 8 for inclusion in the Michigan State Implementation Plan (SIP). Michigan submitted these SIP revisions to meet the Moderate Volatile Organic Compound and Nitrogen Oxide Reasonably Available Control Technology (RACT) requirements for the Western Michigan nonattainment areas (Berrien, Western portion of Allegan, and Western portion of Muskegon counties) under the 2015 ozone National Ambient Air Quality Standard. The EPA also proposed to approve MAPCR Rules that limit VOC emissions from consumer products and architectural and industrial maintenance coatings, as SIP strengthening measures for the Western Michigan nonattainment areas under the 2015 ozone standard. In response to a request in a public comment, the EPA is reopening the comment period for 30 days.
