On March 22, 2011, and May 3, 2012, the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), submitted revisions to the Kentucky State Implementation Plan (SIP) on behalf of the Louisville Metro Air Pollution Control District (District). At this time, the Environmental Protection Agency (EPA) is proposing to approve several portions of the submissions that modify the District's air quality regulations as incorporated into the SIP. The revisions to the regulatory portion of the SIP that EPA is proposing 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 (O<INF>3</INF>), 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 is proposing to approve these portions of the SIP revisions because the Commonwealth has demonstrated that these changes are consistent with the Clean Air Act (CAA or Act). EPA will act on the other portions of KDAQ's March 22, 2011, and May 3, 2012, submittals in a separate action.
