The U.S. Army Corps of Engineers will be taking comment until Dec. 28 on a Section 404 Clean Water Act permit application from LG&E and KU Energy Services for new landfill space at the coal-fired Ghent power plant in Carroll and Gallatin counties, Kentucky.
“LG&E/KU proposes to expand their existing authorization under a Standard Permit (LRL-2009-358) on October 24, 2011, for impacts to 50,510 linear feet of stream channels, 1.99 acres of wetland and 1.80 acres of open water bodies,” said a Corps notice. “However, the Standard Permit issued on October 24, 2011, expired on December 31, 2014, and the applicant is required to obtain re-authorization for the remaining impacts to ‘waters of the United States (U.S.)’ listed above. As of December 31, 2014, the applicant had impacted 23,277 linear feet of stream channels, 0.60 acre of wetlands, and 0.06 acre of open water bodies.
“Under the proposal, an adjacent 462 acres would be converted into additional landfill for the placement of Coal Combustion Products (CCP) generated as waste by the power plant. Approximately 241 acres would be used as the waste storage facility, and approximately 221 acres would be used for ancillary facilities such as CCP treatment and transportation facilities, sediment/stormwater ponds, leachate ponds, collection channels, access roads, and a haul road from stockpiles to the landfill.”
Louisville Gas and Electric and Kentucky Utilities are both subsidiaries of PPL Corp. (NYSE: PPL) that work together in areas like this and share common ownership of several power plants.
Located on the Ohio River northeast of Carrollton, Ky., Ghent consists of four coal-fired units. The largest coal plant in the LG&E and KU system, Ghent began commercial operation in 1973. Its four units have a net generating capacity of 1,932 MW. The station consumes an average of 5.5 million tons of coal annually.
