Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

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 (SO2) nonattainment area of Boyd County to attainment of the National Ambient Air Quality Standards (NAAQS) for SO2. Boyd County is located within the Huntington-Ashland, West Virginia (WV)—Kentucky (KY)—Ohio (OH) Metropolitan Statistical Area (MSA), and the Boyd County SO2 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 proposing to approve the redesignation request for the Boyd County SO2 nonattainment area and the maintenance plan for this area. The maintenance plan provides for the maintenance of the SO2 NAAQS in Boyd County for the next ten years. EPA is also proposing to approve the source-specific SIP revision for the Calgon Carbon Corporation facility.
