Approval and Promulgation of State Implementation Plan Revisions to Permits, Rules and Approval Orders; Utah

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).
