What it does

The Environmental Protection Agency (EPA) is proposing 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 (VOC) and Nitrogen Oxide (NO<INF>X</INF>) 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 (NAAQS or standard). The EPA is also proposing 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. The Michigan Department of Environment, Great Lakes, and Energy (Michigan or EGLE) submitted the VOC SIP revisions on March 7, 2024, supplementing the submittal on May 2, 2024, and submitted the NO<INF>X</INF> SIP revisions on May 5, 2025, supplementing the submittal on August 6, 2025.
