Download Data

Trimble County Generating Station has 28 groundwater monitoring wells, 20 of which have been polluted above federal advisory levels based on samples collected between June 21, 2010 and September 11, 2019. Groundwater at this site contains unsafe levels of boron, sulfate, arsenic, cobalt, molybdenum, lithium, selenium, fluoride, lead and radium.

Site description

Trimble County Generating Station is a power plant located near Bedford, Kentucky, along the Ohio River in Trimble County. The plant, which is owned by Louisville Gas and Electric Company, has been in operation since 1990. The plant has a total capacity of 2,234-MW, with two coal-fired units (Unit 1 with a capacity of 514-MW and Unit 2 with 760-MW) and 6 combustion turbines (each with a capacity of 160-MW).

The station operates two CCR units: Bottom Ash Pond (BAP) and Gypsum Storage Pond (GSP). The BAP is approximately 95 acres and the GSP (north of the BAP) is approximately 33 acres and they share a common dike between them. The BAP has received wet sluiced fly ash, bottom ash, scrubber sludge and gypsum since it began operation, and has a total storage capacity (empty) of approximately 10.4 million cubic yards. The GSP was originally constructed for use as an emergency fly ash pond, but was never used for that purpose. The GSP remained unused until 2010. The GSP was then put in service for the storage of gypsum only and has a total storage capacity (empty) of approximately 1.8 million cubic yards.
