Abstract
In accordance with the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is redesignating the Indianapolis, Indiana area from nonattainment to attainment for the 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS). The area is comprised of Perry, Wayne, and Center Townships in Marion County, Indiana. EPA is also approving, as a revision to the Indiana State Implementation Plan (SIP), Indiana's maintenance plan for this area. EPA proposed to approve Indiana's redesignation request and maintenance plan on April 30, 2019 and received two public comment submissions.
