Corps seeks comment on Trimble County coal waste facility

The U.S. Army Corps of Engineers office in Louisville, Ky., will be taking public comment until June 23 on a Section 404 Clean Water Act permit application on a new coal waste landfill at the Trimble County power plant.

The permit applicant is LG&E and KU Services Co., which handles service matters for sister utilities Louisville Gas & Electric and Kentucky Utilities. The project location is adjacent wetlands, ponds, and unnamed tributaries to Corn Creek, Barebone Creek, and Browning Branch of Barebone Creek on the existing Trimble County Generating Station property in Bedford, Trimble County, Ky. The permitting covers the creation of a special waste landfill (SWL) and associated facilities for the storage and management of coal combustion residuals (CCR) generated by the power plant.

“Under the proposal, the SWL would encompass approximately 189 acres while an additional 651 acres would be used for associated support facilities including a pipe conveyor and haul roads between the plant and the landfill, a sediment basin, a leachate pond, stormwater diversion and collection channels, access roads, soil borrow and spoil areas, and utility relocation,” the Corps noted.

The proposed landfill area would be filled with a synthetic liner, a leachate collection system, and a protective clay liner. The landfill would store approximately 33.4 million cubic yards of CCRs over an expected 37-year life. There would be no disposal of trash, construction/demolition debris, asbestos, or other types of materials or CCR from any other facility at the proposed landfill.

The proposed SWL is regulated by the Kentucky Division of Waste Management (KDWM), which governs the handling, beneficial reuse, and disposal of various types of wastes including utility wastes in Kentucky. An application to construct the landfill was submitted to the KDWM in January

Trimble County, LG&E’s newest power plant, is situated on more than 2,200 acres in a rural setting along the Ohio River in Trimble County, 50 miles northeast of Louisville. The coal units are TC1, a pulverized-coal unit with a net rated capacity of 514 MW; and TC2, a pulverized-coal unit with a net rated capacity of 760 MW. TC1 went into commercial operation in December 1990. TC2 began commercial operation in January 2011. The site also has several combustion turbine units.
