## Abstract

The EPA is taking final action to conditionally approve all but one of the State Implementation Plan (SIP) revisions submitted by the State of Utah on August 20, 2013, with supporting administrative documentation submitted on September 12, 2013. These submittals revise the Utah Administrative Code (UAC) that pertain to the issuance of Utah air quality permits for major sources in nonattainment areas. The EPA is not taking final action on the portion of the August 20, 2013 submittal that revised rule R307-420 at this time. The EPA is taking final action to conditionally approve the other revisions because, while the submitted revisions to Utah's nonattainment permitting rules do not fully address the deficiencies in the state's program, Utah has committed to address additional remaining deficiencies in the state's nonattainment permitting program no later than a year from the EPA finalizing this conditional approval. Upon the EPA finding of a timely meeting of this commitment in full, the final conditional approval of the SIP revisions would convert to a final approval of Utah's plan. This action is being taken under section 110 of the Clean Air Act (CAA) (Act).
