TVA Updates Plans for Stormwater and Runoff at Cumberland
KNOXVILLE, Tenn. – The Tennessee Valley Authority is revising some aspects of previously announced plans for management of coal combustion residuals at its Cumberland Fossil Plant in Stewart County, Tennessee.
As announced in June 2018, TVA plans to construct a new dry storage landfill onsite, close in place the bottom ash impoundment and remove some of the material from the main coal ash impoundment and stilling impoundment, along with building a facility to dewater bottom ash.
TVA now plans an additional 68 acres of land for the project to allow room for new stormwater pond locations and a new tank farm to treat leachate. Plans also include moving ash excavated from the main ash pond into the new dry landfill, once constructed. Overall environmental impacts of the changes would be minor.
Details of the project and updates can be found in a revised Record of Decision posted in the Power Generation – Coal and Gas section at www.tva.com/nepa.
TVA is holding on permanent decisions about the disposal of CCR at Cumberland while an environmental investigation is under way in cooperation with TDEC is completed.
These projects support TVA’s commitment to convert from wet to dry handling and storage of CCR at Cumberland and other coal-fired plants across the service area.
