الملخص

The Environmental Protection Agency (EPA) is finalizing approval and finalizing the conditional approval of portions of the fine particulate matter (PM 2.5 ) State Implementation Plan (SIP) and other general rule revisions submitted by the State of Utah. The revisions affect the Utah Division of Administrative Rules (DAR), R307-300 Series; Requirements for Specific Locations. The revisions had submission dates of May 9, 2013, May 20, 2014, September 8, 2015, and March 8, 2016. The March 8, 2016 submittal contains rule revisions to address our February 25, 2016 conditional approval of several Utah DAR R307-300 Series rules submitted on February 2, 2012, May 9, 2013, and May 20, 2014. These area source rules control emissions of direct PM 2.5 and PM 2.5 precursors, which are sulfur dioxides (SO 2 ), nitrogen oxides (NO X ) and volatile organic compounds (VOC). Additionally, the EPA is finalizing to approve the State's reasonably available control measure (RACM) determinations for the rule revisions that pertain to the PM 2.5 SIP. This action is being taken under section 110 of the Clean Air Act (CAA or Act).
