Approval and Promulgation of Implementation Plans; Wisconsin

The United States Environmental Protection Agency (USEPA) approves revisions to Wisconsin's State Implementation Plan (SIP) for ozone which were submitted to the USEPA on April 17, 1990, and June 30, 1994, and supplemented on July 15, 1994. Included in these revisions is a volatile organic compound (VOC) regulation which establishes reasonably available control technology (RACT) for screen printing facilities. Additionally, the State has submitted current negative declarations for pre-1990 Control Technology Guideline (CTG) categories for which Wisconsin does not have rules as well as a list of major sources affected by the 13 CTG categories that USEPA is required to issue pursuant to sections 183(a), 183(b)(3) and 183(b)(4) of the Clean Air Act (Act). These revisions were submitted to address, in part, the requirement of section 182(b)(2)(B) of the Act that States adopt RACT regulations for sources covered by pre-1990 CTG documents, and the requirement of section 182(b)(2)(C) of the Act that States revise their SIPs to establish RACT regulations for major sources of VOCs for which the USEPA has not issued a CTG document. In the proposed rules section of this Federal Register, the USEPA is proposing approval of and soliciting public comment on this requested SIP revision. If adverse comments are received on this action, the USEPA 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.
