Millions of tons of toxic coal ash is piling up in power plant ponds in 32 states, a situation the government has long recognized as a risk to human health and the environment but has done nothing about.
An Associated Press analysis of the most recent Energy Department data found that 156 coal-fired power plants store ash in surface ponds similar to one that ruptured last month in Tennessee. On Friday, a pond at a northeastern Alabama power plant spilled a different material.
Records indicate that states storing the most coal ash in ponds are Indiana, Ohio, Kentucky, Georgia and Alabama.
The man-made lagoons hold a mixture of the noncombustible ingredients of coal and the ash trapped by equipment designed to reduce air pollution from the power plants.
Over the years, the volume of waste has grown as demand for electricity increased and the federal government clamped down on emissions from power plants.
The AP's analysis found that in 2005, the most recent year data is available, 721 power plants generating at least 100 megawatts of electricity produced 95.8 million tons of coal ash. About 20 percent — or nearly 20 million tons — ended up in surface ponds. The remainder ends up in landfills, or is sold for use in concrete, among other uses.
And while other states like Ohio have regulations to protect groundwater, those often don't apply to many of the older dumps built before the state rules were imposed.
"The solution is readily available to the EPA," said Lisa Evans, an attorney for Earthjustice, an environmental advocacy group. "We wouldn't like it, but they could say that municipal solid waste rules apply to coal ash. They could have done that, but instead they chose to do absolutely nothing."
