## Abstract

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Delaware through the Delaware Department of Natural Resources and Environmental Control (DNREC). Delaware's SIP revision addresses requirements of the Clean Air Act (CAA) and EPA's rules that require states to submit periodic reports describing progress towards reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the state's existing implementation plan addressing regional haze (regional haze SIP). EPA is approving Delaware's SIP revision on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period for regional haze.
