The Tennessee Valley Authority is moving forward with plans to expand the boundaries of an onsite dry storage landfill for coal combustion residuals at Kingston Fossil Plant near Harriman, Tn.
TVA operates a permitted state-of-the-art dry landfill on TVA property at Kingston for coal ash and gypsum, which is produced by the air emissions controls at the plant. The landfill is designed for two phases. The first phase has been in operation since 2015. TVA is proposing to expand the boundary of the construction support area for the onsite gypsum landfill by an additional 21 acres to prepare for the next phase of the landfill. This additional land would be used as a staging area for equipment and as a source of clay borrow material, which will be used in the construction of a new phase of the landfill.
TVA prepared an amended supplemental Environmental Assessment that explains the expansion of the support area, and considered the potential impacts. The final document and associated materials are available for review at www.tva.com/nepa.
TVA already has a construction permit for the next phase of the landfill. However, TVA has applied for other required permits through the Tennessee Department of Environment and Conservation, which includes a public hearing and comment period.
