Approval and Promulgation of Implementation Plans; Kentucky; 
Redesignation of the Boyd County SO2 Nonattainment Area

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.
