Workers and equipment work to clear Swamp Pond Road and the Rail Road tracks near the entrance to the TVA Kingston Steam Plant, Monday, Dec. 29, 2008, near Kingston, Tenn. The spill of more than a billion gallons of coal ash from a power plant in East Tennessee may change the way the nation's largest government-owned utility stores coal waste. Roane County officials are pushing the Tennessee Valley Authority to quit using large retention ponds filled with water and fly ash, a byproduct of coal-fired power plants.
