Approval and Promulgation of Air Quality Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Wisconsin

The EPA is making a determination that Manitowoc and Door Counties in Wisconsin have attained the one-hour ozone National Ambient Air Quality Standard (NAAQS), and we are approving the State of Wisconsin's request to redesignate Manitowoc and Door Counties to attainment for ground level ozone. In approving this redesignation request, we are also approving the State's plan for maintaining the one-hour ozone standard for the next 10 years as a revision to the Wisconsin State Implementation Plan (SIP). We are notifying the public that we believe the motor vehicle emissions budgets for volatile organic compounds (VOC) and oxides of nitrogen (NO<INF>X</INF>) in the maintenance plan for Manitowoc and Door Counties are adequate for conformity purposes and approvable as part of the maintenance plan. In this direct final rule, we are also approving a 1999 periodic inventory for the Milwaukee-Racine ozone nonattainment area. The Wisconsin Department of Natural Resources (WDNR) submitted the redesignation request and SIP revisions on January 28, 2003, and submitted additional information on February 5, 2003 and February 27, 2003.
