In a single year, a coal-fired electric plant deposited more than 2.2 million pounds of toxic materials in a holding pond that failed last week, flooding 300 acres in East Tennessee, according to a 2007 inventory filed with the Environmental Protection Agency. The inventory, disclosed by the Tennessee Valley Authority on Monday at the request of The New York Times, showed that in just one year, the plant's byproducts included 45,000 pounds of arsenic, 49,000 pounds of lead, 1.4 million pounds of barium, 91,000 pounds of chromium and 140,000 pounds of manganese. Those metals can cause cancer, liver damage and neurological complications, among other health problems. And the holding pond, at the Kingston Fossil Plant, a T.V.A. plant 40 miles west of Knoxville, contained many decades' worth of these deposits. For days, authority officials have maintained that the sludge released in the spill is not toxic, though coal ash has long been known to contain dangerous concentrations of heavy metals. On Monday, a week after the spill, the authority issued a joint statement with the E.P.A. and other agencies recommending that direct contact with the ash be avoided and that pets and children should be kept away from affected areas. [...] "They think that the public is stupid, that they can't put two and two together," said Sandy Gupton, a registered nurse who hired an independent firm to test the spring water on her family's 300-acre farm, now sullied by sludge from the spill. "It took five days for the T.V.A. to respond to us."

The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
The spill has reignited a debate over whether coal ash should be regulated as a hazardous waste. In 2000, the E.P.A. backed away from its recommendation to do so in the face of industry opposition, promising instead to issue national guidelines for proper ash disposal, though it never did.
I can't identify exactly who is responsible for structural oversight of the retention ponds - the EPA, another federal authority of the state.
Here's a from-the-water view of the disaster:
