Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; State of Illinois

The USEPA is approving a November 10, 1994 State Implementation Plan (SIP) revision request to redesignate two sulfur dioxide (SO<INF>2) nonattainment areas in the State of Illinois to attainment and approving the accompanying maintenance plans as SIP revisions because they satisfy the requirements of the Clean Air Act (Act). The redesignation requests and maintenance plans were submitted by the Illinois Environmental Protection Agency (IEPA) for the following SO<INF>2 nonattainment areas: Peoria County (Hollis and Peoria Townships) and Tazewell County (Groveland Township). The redesignation requests are based on ambient monitoring data and modeling demonstrations that show no violations of the SO<INF>2 National Ambient Air Quality Standard (NAAQS). In the proposed rules section of this Federal Register, USEPA is proposing approval of and soliciting public comments on these requested redesignations and SIP revisions. If adverse comments are received on this direct final rule, USEPA will withdraw this final rule and address these comments in a final rule on the related proposed rule which is being published in the proposed rules section of this Federal Register. Adverse comments received concerning a specific geographic area, Peoria or Tazewell Counties, will only affect this final rule as it pertains to that area and only the portion of this final rule concerning the area receiving adverse comments will be withdrawn.
