Environmental groups concerned about TVA landfill

KINGSTON, Tenn. (AP) – Environmental groups are criticizing a plan by the Tennessee Valley Authority to expand a Kingston landfill used for waste from the coal-burning power plant.

The Knoxville News Sentinel reports (http://bit.ly/1wwfuZ7 ) at least a half dozen groups have expressed concerns that the site is prone to sinkholes that would allow the landfill waste to migrate to the Clinch River. The concerns were expressed as part of a public comment period on the landfill expansion.

TVA said in a statement that the landfill is part of the utility’s planned conversion from wet storage of coal ash to dry storage and will be built in accordance with state regulations.

The 2008 failure of a wet storage pond in Kingston caused a spill of more than 5 million cubic yards of coal ash sludge.
