Abstract
The Environmental Protection Agency (EPA) is redesignating the Lemont and Pekin sulfur dioxide (SO<INF>2</INF>) areas from nonattainment to attainment of the 2010 SO<INF>2</INF> national ambient air quality standard (2010 SO<INF>2</INF> NAAQS). EPA is also approving Illinois' maintenance plan for these areas. Emissions of SO<INF>2</INF> in the two areas have been reduced, and the areas' monitored air quality is currently better than the 2010 SO<INF>2</INF> NAAQS. EPA proposed to approve this action on February 24, 2020 and received two public comment submissions.
