The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions, which Illinois submitted to EPA on March 2, 2016, and supplemented on August 8, 2016 and May 4, 2017, for attaining the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS) for the Lemont and Pekin areas. These revisions (herein called the nonattainment plans or plans) include Illinois' attainment demonstration and other elements required under Clean Air Act (CAA) for the two areas. In addition to an attainment demonstration, the plans address: The requirement for meeting reasonable further progress (RFP) toward attainment of the NAAQS; reasonably available control measures and reasonably available control technology (RACM/RACT); emission inventories; and contingency measures. EPA further proposes to conclude that Illinois has demonstrated that the plans' provisions provide for attainment of the 2010 1-hour primary SO<INF>2</INF> NAAQS in the Lemont and Pekin areas by the attainment date of October 4, 2018.
