The Environmental Protection Agency (EPA) is approving the volatile organic compounds (VOC) reasonably available control technology (RACT) State Implementation Plan (SIP) revision, submitted by the Wisconsin Department of Natural Resources (WDNR or Wisconsin) on January 21, 2020 and February 12, 2020. The Clean Air Act (CAA) requires states to implement RACT in ozone nonattainment areas classified as moderate (and higher). EPA finds Wisconsin's two VOC RACT SIP submissions to be approvable as meeting the moderate VOC RACT requirements of the CAA.
