## Abstract

EPA is approving revisions to the State of Michigan's Clean Air Act New Source Review (NSR) State Implementation Plan (SIP), including the Part 1 general provisions rules and the Part 19 rules for major sources in nonattainment areas. The Michigan Department of Environmental Quality (MDEQ) submitted the revisions to address, among other things, the Federal NSR reform rules. EPA is also removing Michigan rule 336.1220 from the Michigan SIP. This rule is being replaced by applicable language found in Michigan's Part 19 NSR rules. MDEQ submitted these revisions to EPA on March 24, 2009.
