McClatchy Newspapers WASHINGTON — The coal ash spill in Tennessee last month is putting a spotlight on whether the ash from 450 other power plants around the country could be contaminating the nation's drinking water supplies.
Some coal ash is recycled into products such as cement or placed in secure landfills, but much of it ends up in gravel pits, abandoned mines and unlined landfills — or in ponds like the one that burst in Kingston, Tenn., on Dec. 22. In the Tennessee incident, 5.4 million cubic yards of sludge laced with arsenic and other toxic materials poured over 300 acres — making it one of the nation's worst environmental spills.
The EPA in 2000 decided that coal ash wasn't hazardous waste and left regulation up to the states. Now, however, environmental activists say the Tennessee spill shows the need for federal standards for how coal waste is handled at the coal-fired power plants around the nation.
"It's an insanely dangerous scenario that's been allowed to develop, but it's all under the radar screen," said Jeffrey Stant of the Environmental Integrity Project, a group formed by former EPA enforcement attorneys that's compiling data on coal ash disposal sites.
