Barbara Martocci, TVA spokeswoman, said the Dam Safety Group will take over the inspection of all the utility’s impoundments in 2011. And the utility is also taking steps to eliminate wet ash storage facilities at all its power plant locations.

Coal ash storage ponds have come under scrutiny since December 2008, when a coal ash impoundment pond at the TVA Kingston plant breached, sending a wave of toxic material on to a neighboring rural community.

Despite containing heavy metals that have been linked to serious health problems, coal ash isn’t classified as a hazardous material. Thus, facilities that store coal ash weren’t regulated by the federal government. Critics say that if the plants had been properly regulated and inspected, perhaps the massive spill that blanked an east Tennessee community with toxic material may not have happened in the first place.

The TVA, meanwhile, is involved in a years-long, multi-million dollar cleanup of the land and is facing a mountain of lawsuits from people who were harmed or lost property in the coal ash disaster. The customers of the nation’s largest utility will soon feel the pain, too, as that hefty expense is likely to translate into higher residential utility bills.

That spill, called one of the largest environmental disasters in U.S. history, knocked houses off their foundations, damaged property and contaminated waterways. The TVA is currently undergoing an estimated three-year, $1.2 billion cleanup effort to restore the land.

That’s just the kind of nightmare Kentucky residents don’t want to experience. A major spill from a larger coal ash pond built on the Ohio River flood plain could easily contaminate Louisville’s drinking water uptake just 30 miles downstream.

LG&E and Kentucky Division of Water officials say the pond wouldn’t affect the drinking water. But environmentalists have concerns. Coal ash is not categorized as a hazardous material and thus does not currently fall under federal regulation. But the massive Tennessee spill shed new light on coal ash.

Tests have shown that coal ash contains dangerous toxins such as arsenic, lead, chromium, manganese and barium, which have been linked to serious health conditions such as cancer, liver damage and neurological complications. As a result of last year’s devastating spill, the Environmental Protection Agency has been ordered to review all coal ash ponds in the country. The agency is expected to issue new rules for handling coal ash sometime in December.
