The Environmental Protection Agency (EPA) is taking final action to approve portions of the State Implementation Plan (SIP) submission submitted by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), on behalf of the Louisville Metro Air Pollution Control District (District), on March 22, 2011, and May 3, 2012. The revisions to the regulatory portion of the SIP that EPA is taking final action to approve pertain to changes to the District's air quality standards for lead (Pb), particulate matter (both PM<INF>2.5</INF> and PM<INF>10</INF>), ozone, nitrogen dioxide (NO<INF>2</INF>), and sulfur dioxide (SO<INF>2</INF>) to reflect the National Ambient Air Quality Standards (NAAQS), definitional changes, and regulatory consolidation. EPA has determined that these portions of the March 22, 2011, and May 3, 2012, SIP revisions are consistent with the Clean Air Act (CAA or Act).
