The Environmental Protection Agency (EPA) is proposing to approve a regional haze progress report State Implementation Plan (SIP) revision submitted by the State of Wyoming on November 28, 2017. The revision addresses the requirements for states to submit periodic reports describing progress toward reasonable progress goals established for regional haze and a determination of adequacy of the State's existing regional haze SIP and federal implementation plan (FIP). The regional haze progress report SIP revision also includes a revision to the Best Available Retrofit Technology (BART) requirements for Unit 3 at the Naughton Power Plant. The EPA acted on the BART revision for the Naughton Power Plant in a previous rulemaking and is not proposing to act on the BART revision in this rulemaking. The EPA is taking this action pursuant to section 110 of the Clean Air Act (CAA).
