Abstract
On May 4, 2018, the Commonwealth of Kentucky, through the Kentucky Energy and Environment Cabinet, Division for Air Quality (KDAQ), submitted a request for the Environmental Protection Agency (EPA) to redesignate the portion of Kentucky that is within the bi- state Louisville, KY-IN fine particulate matter (PM<INF>2.5</INF>) unclassifiable area (hereinafter referred to as the "bi-state Louisville Area" or "Area") to unclassifiable/attainment for the 2012 primary annual PM<INF>2.5</INF> national ambient air quality standard (NAAQS). The bi-state Louisville Area consists of Jefferson County and a portion of Bullitt County in Kentucky, as well as Clark and Floyd Counties in Indiana. EPA is approving the State's request and redesignating the Area to unclassifiable/attainment for the 2012 primary annual PM<INF>2.5</INF> NAAQS based upon valid, quality- assured, and certified ambient air monitoring data showing that the PM<INF>2.5</INF> monitors in the bi-state Louisville Area are in compliance with the 2012 primary annual PM<INF>2.5</INF> NAAQS.
