Proposed Landfill Expansion at Kingston Fossil Plant

Roane County, Tennessee

The Tennessee Valley Authority (TVA) proposes to expand the boundary for the on-site landfill at Kinston Fossil Plant (KIF), near Harriman, Tennessee, to include additional acreage for a new laydown area, clay soil borrow site and a haul road. The proposed action is needed so TVA can adequately and effectively construct the second phase of the landfill.  

In 2006, TVA completed the Flue Gas Desulfurization System at Kingston Environmental Assessment (EA) and issued a Finding of No Significant Impact (FONSI) for the installation of flue gas scrubber equipment to reduce sulfur dioxide (SO2) emissions from the stack. The byproduct of the scrubber, gypsum, required the construction of a new landfill disposal facility. An on-site landfill location was chosen at the southern end of the KIF property. In 2010, TVA completed the Kingston Dry Fly Ash Conversion EA and issued a FONSI for the material that would be disposed of in the landfill (dry fly ash, bottom ash and gypsum).

The landfill was designed for two phases. Phase 1 was constructed in 2015 and is approaching its full capacity. Phase 2 is needed to support the continued operation of KIF. The 2006 and 2010 EAs did not analyze any laydown area or borrow area to support the construction of Phase 2 of the landfill.

On February 14, 2018, TVA released a draft supplemental EA of the proposed expansion of the landfill boundary for public comment. The comment period closed on March 15, 2018.  TVA is currently reviewing the comments received during the comment period and will incorporate them into the final assessment.
