Coal slurry for a Tennessee Christmas
At 1 a.m. on Dec. 22, some 500 million gallons of coal sludge flooded 15 homes in a 400-acre area west of Knoxville. Unleashed by a break in a waste-pond retaining wall at the Tennessee Valley Authority’s Kingston coal-fired plant, the wave of mud and coal ash knocked at least one home off its foundation and was as deep as 6 feet as it rushed downstream.
