Shawnee Fossil Plant Bottom Ash Process Dewatering Facility
McCracken County, Tennessee
TVA has completed an Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for a Shawnee Fossil Plant Bottom Ash Process Dewatering Facility. Shawnee Fossil Plant (SHF) is located on 1,696 acres adjacent to the Ohio River about 10 miles northwest of Paducah, Kentucky. It has nine active coal-fired generating units with a summer net capability of 1,206 megawatts and can generate about 8 billion kilowatt-hours of electricity per year, which is enough to supply 540,000 homes.
In July 2009, the Tennessee Valley Authority (TVA) Board of Directors passed a resolution that called for the development of a Fossil Remediation Plan that addressed all coal combustion residual (CCR) impoundments at TVA’s fossil plants. TVA subsequently reviewed its practices for handling and storing CCRs at its generating facilities, including, Shawnee Fossil Plant (SHF). An outcome of that review was to a consideration to end wet storage of coal ash and gypsum and convert to dry storage.
The purpose of the proposed action is to help TVA meet its commitment to convert CCR storage from wet to dry, complement compliance with EPA’s Disposal of Coal Combustion residuals from Electric Utilities Rule (CCR Rule) and enhance compliance with EPA’s Effluent Limitation Guidelines and Standards for the Steam Electric Power Generating Point Source Category (ELGs).
This EA informs TVA decision makers and the public about the environmental consequences of the proposed action. TVA’s preferred alternative in the EA is to construct a process dewatering facility and include a recirculation system to recycle sluice water back into the powerhouse for future sluicing operations.
