Sheboygan Wisconsin 2015 Ozone Moderate Attainment Plan

Wisconsin has submitted a state implementation plan (SIP) for Sheboygan County addressing the 2015 Ozone National Ambient Air Quality Standards (NAAQS). As a Moderate nonattainment area, Sheboygan must demonstrate attainment by an applicable deadline and implement required control measures under Clean Air Act Section 182(b). The plan likely includes emissions inventories, reasonably available control measures, and a modeling demonstration showing the area will achieve the 70 ppb ozone standard.

Industrial sources and facilities in Sheboygan County should review the plan for new or revised emissions requirements, monitoring obligations, or control technology mandates. Wisconsin's environmental agency and local industries should monitor EPA's review and be prepared to address any deficiencies identified during the approval process. Public comment opportunities may arise once EPA proposes action on the SIP.
