Approval and Promulgation of Implementation Plans; Wisconsin

The purpose of this action is to propose approval of the State of Wisconsin's Prevention of Significant Deterioration (PSD) rules, Natural Resources (NR) 405.01 through NR 405.17, as a revision to the Wisconsin State Implementation Plan (SIP). The State developed rules as Wisconsin's plan to prevent significant deterioration of air quality in areas designated as unclassifiable or attainment of the National Ambient Air Quality Standards (NAAQS) and to satisfy the requirements of part C of the Clean Air Act (Act). EPA is approving these rules because they meet EPA's regulation governing State PSD programs. In addition to the PSD rules, Wisconsin has submitted rules as a revision to the SIP to establish breathable particulates (PM-10) as a basis for the determination of particle concentrations for permitting purposes under the PSD program and, therefore, tie the new source permit evaluations directly to human health standards. Finally, Wisconsin submitted as a revision to the SIP changes of a ``clean-up'' nature, intended to correct errors in content or style, to improve consistency, or clarify existing policy and procedures.
