1.0 Introduction/BackgroundOn March 2, 2015, the U.S. District Court for the Northern District of California issued a court orderaccepting a consent decree between the U.S. Environmental Protection Agency (U.S. EPA), SierraClub, and Natural Resources Defense Council resolving litigation concerning the deadline for U.S.EPA to complete area designations for the 2010 1-hour SO2 National Ambient Air Quality Standard(NAAQS). Per the court order, U.S. EPA will complete the area designations in three additionalrounds: the first round by July 2, 2016, the second round by December 31, 20

3.1 Newton Power Station (Jasper County) . U.S. EPA identified five electric generating facilities in Illinois that meet the stationary source criteria established in the court’s order. These five facilities are listed in Table 1 and their locations are shown in Figure 1. This report provides Illinois’ area designation recommendations for each of these five facilities, and the technical .
