Abstract
On May 13, 2005, and later clarified in a July 12, 2005, supplemental submittal, the Commonwealth of Kentucky submitted a request to redesignate the sulfur dioxide (SO<INF>2</INF>) nonattainment area of Boyd County to attainment of the National Ambient Air Quality Standards (NAAQS) for SO<INF>2</INF>. Boyd County is located within the Huntington-Ashland, West Virginia (WV)-Kentucky (KY)-Ohio (OH) Metropolitan Statistical Area (MSA), and the Boyd County SO<INF>2</INF> nonattainment area is comprised of the southern portion of Boyd County. The Commonwealth also submitted, as revisions to the Kentucky State Implementation Plan (SIP), a maintenance plan for the area and a source-specific SIP revision for the Calgon Carbon Corporation facility in Catlettsburg, Kentucky. EPA is approving the redesignation request for the Boyd County SO<INF>2</INF> nonattainment area and the maintenance plan for this area. The maintenance plan provides for the maintenance of the SO<INF>2</INF> NAAQS in Boyd County for the next ten years. EPA is also approving the source-specific SIP revision for the Calgon Carbon Corporation facility.
