## Abstract

The EPA is approving revisions to particulate matter (PM) regulations for Richmond Power and Light Company (RPL) of Wayne County, Indiana. EPA proposed approval of these regulations, 326 Indiana Administrative Code (IAC) 6-1-14, on April 9, 2003. EPA did not receive any comments on the proposed rule. As a result, the long-term (annual) limits for RPL will be consistent with the short-term limits. Modeling analysis show that air quality is expected to be maintained.
