Approval and Promulgation of Implementation Plans; Illinois

On October 21, 1993, and March 4, 1994, the Illinois Environmental Protection Agency (IEPA) submitted to the USEPA volatile organic compound (VOC) rules that were intended to satisfy part of the requirements of section 182(b)(2) of the Clean Air Act (Act) amendments of 1990. Specifically, these rules provide control requirements for certain major sources not covered by a Control Technique Guideline (CTG) document. These non-CTG VOC rules apply to sources in the Chicago ozone nonattainment area which have the potential to emit 25 tons of VOC per year. These rules provide an environmental benefit due to the imposition of these additional control requirements. IEPA estimates that these rules will result in VOC emission reductions, from 119 industrial plants, of 2.78 tons per day. The rationale for the approval is set forth in this final rule; additional information is available at the address indicated below. Elsewhere in this Federal Register USEPA is proposing approval and soliciting public comment on this requested revision to the Illinois State implementation plan (SIP). If adverse comments are received on this direct final rule, USEPA will withdraw the final rule and address the comments received in a new final rule. Unless this final rule is withdrawn, no further rulemaking will occur on this requested SIP revision.
