After 2008 Failure, TVA Boosts Coal-Ash Sites at Powerplants
The Tennessee Valley Authority, Knoxville, Tenn., has awarded San Francisco-based URS Corp. a five-year, $20- million contract to provide engineering and construction management services for conversion of wet coal-ash storage facilities at five coal plants to dry storage systems. The upgrade follows the 2008 storage pond failure at a TVA plant in Kingston, Tenn.
Under the contract, URS will handle conversion of storage systems at the Colbert, Widows Creek, Gallatin, Bull Run and John Sevier power plants, located elsewhere in Tennessee and in Alabama. TVA agreed to move to dry coal-ash storage systems after the Kingston coal-ash impoundment collapsed, contaminating thousands of nearby acres and the Emory River.
