## Abstract

In this action, EPA is approving two redesignation requests submitted by the State of Indiana. On March 14, 1996, Indiana requested that a portion of Marion County be redesignated to attainment of the National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO<INF>2). On June 17, 1996, Indiana requested that portions of LaPorte and Wayne Counties and all of Vigo County be redesignated to attainment for SO<INF>2. The EPA is also approving the maintenance plans for Marion, LaPorte, Vigo, and Wayne Counties, which were submitted with the redesignation requests to ensure maintenance of the NAAQS. Subsequent to this approval, Marion, LaPorte, Vigo, and Wayne Counties are each designated attainment in their entirety.
