The Tennessee Valley Authority is seeking public comments on its draft Environmental Assessment for proposed remediations to the detention dam at the John Sevier Combined Cycle Plant in Rogersville. The draft EA is available for a 30-day public review and comment period at www.tva.com/nepa
TVA’s recommended action is Alternative C. TVA would construct a Roller Compacted Concrete Gravity Dam to help address the risk of potential erosion to the earthen embankment dam at the site.
The new dam would be constructed downstream of the existing north embankment and will connect to the northern end of the existing concrete overfall spillway. This will require minimal modifications to the current dam.
Comments can be submitted through June 30 by email to firstname.lastname@example.org, submitted online at www.tva.com/nepa or mailed to Erica McLamb, Tennessee Valley Authority 1101 Market St., Chattanooga, Tn. 37402. All comments received, including names and addresses, will become part of the project administrative record and will be available for public inspection.
The John Sevier Combined Cycle Plant is an 871-megawatt facility that can use natural gas or fuel oil for combustion. It is located on 750 acres beside the Holston River near Rogersville, and began commercial operation on April 30, 2012.
