Kingston Fossil Plant Bottom Ash Dewatering Facility

Roane County, Tennessee

TVA has completed an Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for a Kingston Fossil Plant Bottom Ash Dewatering Facility near Harriman, Tennessee.

In August 2009, the TVA Board of Directors passed a resolution to review and address systems, controls, and standards related to coal combustion products (CCPs) (i.e. fly ash, bottom ash, and gypsum), which result from the burning of coal to produce electricity. TVA has subsequently reviewed its practices for handling and storing CCPs at its generating facilities, including its coal-fired Kingston Fossil Plant (KIF). An outcome of that review was to consider the conversion of the wet storage of CCP to the dry storage at KIF.

A Draft EA for this project was released for public comment from April 2, 2015 - May 5, 2015.  In response to a number of comments regarding recirculation and reduction of water discharge, TVA revised the Draft EA and held a second public comment period.  TVA’s preferred alternative is to construct a dewatering facility and a recirculation facility to recycle sluice water back into the powerhouse for future sluicing operations. This alternative provides long-term benefits, and meets the purpose and need of the project by supporting TVA's dry CCR storage approach and fostering compliance with EPA’s Effluent Limitations Guidelines.
