## Abstract

On November 21, 1997, the Commonwealth of Kentucky submitted, through the Natural Resources and Environmental Protection Cabinet (the Cabinet), a request for redesignation of Muhlenberg County, Kentucky, to attainment for the secondary sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS). The secondary nonattainment designation for SO<INF>2</INF> was based on the fact that the Tennessee Valley Authority (TVA) Paradise Steam Plant was out of compliance with its allowable emission limit. The Cabinet submitted air dispersion modeling which demonstrates that the secondary (NAAQS) for SO<INF>2</INF> are now being maintained. The EPA is approving the request for redesignation.
