## Abstract

EPA is approving a June 17, 2005, Michigan petition for exemptions from the Reasonably Available Control Technology (RACT) and New Source Review (NSR) requirements for major sources of nitrogen oxides (NO<INF>X</INF>). The petition is for sources in six of Michigan's eight-hour ozone nonattainment areas, which comprise eleven counties. EPA proposed approval of the petition in a January 5, 2006 rulemaking action. Section 182(f) of the Clean Air Act allows this exemption for areas where additional reductions in NO<INF>X</INF> will not contribute to attainment of the ozone standard. The Grand Rapids, Kalamazoo/Battle Creek, Lansing/East Lansing, Benzie County, Huron County, and Mason County nonattainment areas will each receive an exemption.
