{"abstract":"The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Utah on January 4, 2016, which include revisions to Utah's Division of Administrative Rule (DAR) R307-110-10 and maintenance plans for the Salt Lake County, Utah County, and Ogden City nonattainment areas (NAAs) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 microns (PM<INF>10</INF>), and on March 6, 2019, which include PM<INF>10</INF> redesignation requests and supplemental information for Salt Lake County, Utah County and Ogden City. These submittals demonstrate that the Salt Lake County, Utah County and Ogden City areas have attained the PM<INF>10</INF> National Ambient Air Quality Standards (NAAQS), request redesignation to attainment and include maintenance plans for the areas demonstrating attainment for fifteen years. Also, the EPA is proposing approval of Utah's February 27, 2017 submittal, which includes rule revisions to address our October 19, 2016 conditional approval of Utah's DAR R307- 302 revisions that were submitted May 9, 2013, May 20, 2014, and September 8, 2015. Additionally, the EPA is proposing to approve SIP revisions submitted by the State of Utah on February 15, 2019, with additional non-substantive changes submitted on July 1, 2019, August 20, 2019, and October 15, 2019, which includes revisions that are located in DAR R307-110-17 and SIP Subsections IX.H.1-2.
