Approval and Promulgation of Implementation Plan; Illinois

On September 11, 1991, and March 15, 1993 the Illinois Environmental Protection Agency (IEPA) submitted to the United States Environmental Protection Agency (USEPA) volatile organic compound (VOC) rules, for the Chicago and East St. Louis ozone nonattainment areas, as requested revisions to Illinois' State Implementation Plan (SIP) for ozone. These rules had been submitted to USEPA to correct deficiencies in its VOC SIP and to expand the geographic applicability of Illinois' VOC rules to all the State's nonattainment areas. IEPA submitted the rules for parallel processing because the rules submitted on March 15, 1993, had not been finally adopted by the State. On September 22, 1993, USEPA proposed to approve these rules. On October 21, 1993, IEPA submitted the finally adopted rules which contained some significant changes. In this rule the USEPA is approving those rules which have not been changed since their initial submission. However, USEPA will be addressing those rules which have been changed in a separate rulemaking action.
