Johnsonville Fossil Plant Decontamination and Deconstruction Draft Environmental Assessment

Humphreys County, Tennessee

On August 20, 2018 TVA released the Draft Environmental Assessment (EA) for the former Johnsonville Fossil Plant and related structures at its site in Humphreys County, Tennessee. TVA accepted comments on the Draft EA until September 19, 2018. TVA is currently reviewing the comments received during the public comment period.

TVA retired all ten units of the coal-fired plant gradually beginning in 2012, with the final four units on Dec. 31, 2017. Prior to that, Johnsonville was the oldest fossil plant in the TVA system.

TVA has prepared a Draft Environmental Assessment to consider the potential environmental impacts of the various options for possible deconstruction and demolition at the site. The EA evaluates seven alternatives, including: (A2) assess, close, and secure site, and implement an operations and maintenance program to maintain structures and equipment; (B) selective demolition of outlying facilities including the coal handling facilities; (C) demolish and grade (“Brownfield”) with sub-options (C1) leaving the stack in place, (C2) drop removal of the stack, (C3) controlled removal of the stack, or (C4) hybrid removal of the stack; or (D) to take no action. 

TVA’s preferred alternative is C, demolition of Units 1-10 and other structures to three feet below final grade (Brownfield), with C2, C3, or C4 for the stack.
