Abstract
The Environmental Protection Agency (EPA) is approving a revision to the Wisconsin State Implementation Plan (SIP). On December 13, 2019, the Wisconsin Department of Natural Resources (WDNR) submitted the State's plans for maintaining the 1997 ozone National Ambient Air Quality Standard (NAAQS or standard) in the following areas: Kewaunee County, Door County, Manitowoc County, and Milwaukee- Racine area (Kenosha, Milwaukee, Ozaukee, Racine, Washington and Waukesha counties). EPA is approving these maintenance plans because they provide for the maintenance of the 1997 ozone NAAQS through the end of the second 10-year maintenance period. This action makes certain commitments related to maintenance of the 1997 ozone NAAQS in these areas federally enforceable as part of the Wisconsin SIP. EPA proposed to approve this action on March 24, 2020 and received no adverse comments.
