The Environmental Protection Agency (EPA) is proposing to approve a revision to the Wisconsin State Implementation Plan (SIP) to meet the volatile organic compound (VOC) and nitrogen oxides (NO<INF>X</INF>) reasonably available control technology (RACT), clean- fuel vehicle programs (CFVP), and the enhanced monitoring of ozone and ozone precursors (EMP) requirements of the Clean Air Act (CAA) in the Wisconsin portion of the Chicago-Naperville, Illinois-Indiana-Wisconsin nonattainment area (Chicago area) for the 2008 ozone National Ambient Air Quality Standards (NAAQS or standards). EPA is proposing to approve this SIP revision pursuant to section 110 and part D of the requirements of the CAA and EPA's regulations, because it satisfies the above requirements for an area which is classified as serious nonattainment for the 2008 ozone NAAQS. Other serious elements will be addressed in a separate action.
