Two years after spill EPA unsure how to classify toxic coal ash
Two years after an impoundment pond containing toxic coal ash at a Tennessee Valley Authority (TVA) fossil fuel plant broke, spilling a billion gallons of sludge onto 300 acres of rural east Tennessee, the Environmental Protection Agency (EPA) still isn’t sure whether to recommend that coal ash be classified as a hazardous material. Shortly after the spill, the agency was charged with recommending a classification for the material as part of a federal investigation into the environmental disaster.
