Abstract
The United States Environmental Protection Agency (USEPA) proposed to approve Wisconsin's request to grant an exemption for the Milwaukee severe and Manitowoc County moderate ozone nonattainment areas from the applicable Oxides of Nitrogen (NOx) transportation conformity requirements on June 12, 1997. The proposal was based on information the Wisconsin Department of Natural Resource (WDNR) submitted to the EPA as a State Implementation Plan (SIP) revision request for an exemption under section 182(b)(1) of the Clean Air Act (Act). The request was based on the urban airshed modeling (UAM) conducted for the attainment demonstration for the Lake Michigan Ozone Study (LMOS) modeling domain. The EPA is temporarily granting this exemption until a control strategy SIP is approved.
