The Clean Air Act (CAA) authorizes EPA to reclassify certain ozone nonattainment areas shortly after the initial classification for such areas. In the April 30, 2004 Federal Register action establishing the 8-hour ozone designations and classifications, we described this reclassification process and listed criteria that we intended to use to evaluate a reclassification request. Requests to reclassify ozone nonattainment areas from moderate to marginal were submitted by the respective States for the following areas: Cass and Muskegon Counties, Michigan; Detroit, Michigan; Greensboro, North Carolina; Kent/Queen Anne Counties, Maryland; Lancaster, Pennsylvania; LaPorte, Indiana; Memphis, Arkansas/Tennessee; and Richmond, Virginia. This rule reclassifies certain areas that are designated nonattainment for the 8-hour ozone national ambient air quality standard (NAAQS).
