Approval and Promulgation of State Implementation Plan; Wisconsin; Iron and Steel Foundries SIP Revision

The EPA approves a revision to the Wisconsin State Implementation Plan (SIP) for ozone that was submitted by the State of Wisconsin on June 30, 1994, and supplemented on July 15, 1994. This revision consists of a volatile organic compound (VOC) regulation which establishes reasonably available control technology (RACT) for iron and steel foundries. This regulation was submitted to address, in part, the requirement of section 182(b)(2)(C) of the Clean Air Act (CAA or Act) that States revise their SIPs to establish RACT regulations for major sources of VOCs for which the USEPA has not issued a control technology guidelines (CTG) document. In addition, emission reductions resulting from this rule are being used by the State to fulfill, in part, the requirement of section 182(b)(1) of the Act that States submit a plan which provides for a 15 percent reduction in VOC emissions by 1996. In the proposed rules section of this Federal Register, the EPA is proposing approval of, and soliciting comments on, this requested SIP revision. If adverse comments are received on this action, the EPA will withdraw this final rule and address the comments received in response to this action in a final rule on the related proposed rule, which is being published in the proposed rules section of this Federal Register. A second public comment period will not be held. Parties interested in commenting on this action should do so at this time. This approval makes federally enforceable the State's rule that has been incorporated by reference.
