Air Plan Approval; Tennessee; Regional Haze Progress Report

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Tennessee through the Tennessee Department of Environment and Conservation (TDEC) on April 19, 2013. Tennessee's April 19, 2013, SIP revision (Progress Report) addresses requirements of the Clean Air Act (CAA or Act) and EPA's rules that require each state 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 SIP addressing regional haze (regional haze plan). EPA is proposing to approve Tennessee's Progress Report on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period for regional haze.
