Environmental Protection Agency July 19, 2016 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is taking direct final action to approve State Implementation Plan (SIP) revisions submitted by the State of Utah on February 10, 2012 and August 29, 2014. These submittals request SIP revisions to remove changes to the major source baseline date that were disapproved by the EPA on July 15, 2011. The submittals also address the EPA's February 6, 2014 disapproval of several permit rules related to the public availability of good engineering practice stack height demonstrations in the public comment process for an approval order, and the process for making emission reductions enforceable in an approval order. The EPA is taking this action in accordance with section 110 of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to approve a source-specific revision to the Arizona State Implementation Plan (SIP) that addresses requirements for best available retrofit technology (BART) at Cholla Generating Station (Cholla). The EPA proposes to find that the SIP revision fulfills the requirements of the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for BART at Cholla. In conjunction with this proposed approval, we propose to withdraw those portions of the federal implementation plan (FIP) that address BART for Cholla. We previously partially granted petitions for reconsideration of that FIP from Cholla's owners, Arizona Public Service Company (APS) and PacifiCorp. We are now proposing to find that final withdrawal of the FIP, as it applies to Cholla, would constitute our action on APS's and PacifiCorp's petitions for reconsideration of the FIP.
