Approval and Promulgation of Implementation Plan: Michigan; NOINFX Exemption Request for East Lansing and Genesee County Transitional Areas

The EPA is proposing to grant oxides of nitrogen (NO X) exemptions to the East Lansing (Ingham, Eaton and Clinton Counties) and Genesee County transitional ozone nonattainment areas. This proposed approval would exempt these areas from the NO X provisions of the general conformity and transportation conformity requirements of the Clean Air Act (Act). The State of Michigan submitted NO X exemption requests on July 1, 1994 and July 8, 1994 for the East Lansing and Genesee County transitional areas, respectively. Ozone monitors in these areas indicated that the average number of exceedances of the National Ambient Air Quality Standard for ozone (ozone standard) during the most recent 3-year monitoring period, 1991 through 1993, is fewer than one per year. Based upon this demonstration that additional reductions of NO X would not contribute to attainment of the ozone standard, Michigan requested that EPA approve a revision to Michigan's State Implementation Plan (SIP) exempting these areas from the requirement to provide conformity analyses for NO X. Additional information is available at the address indicated.
