The Tennessee Valley Authority (TVA) has pledged to clean up the massive coal waste (fly ash) spill in central Kingston, Tennessee. The TVA's initial estimate for the spill tripled from 1.8 million cubic yards, or more than 360 million gallons of sludge, to 5.4 million cubic yards, or more than 1 billion gallons. The sludge is a byproduct of the ash from coal combustion.
A retention pond at the Tennessee Valley Authority's power plant in Kingston, about 40 miles west of Knoxville, contained the waste until a wall breached on December 22, sending the sludge downhill to damage 15 homes and cover at least 300 acres. All the residents were evacuated. The plant sits on Clinch River, a tributary of the Tennessee River. (CNN.com)
