Coal Ash Spill in Tennessee

From the NY Times:
Environmentalists pointed to the accident as proof of their long-held assertion that there is no such thing as “clean coal,” noting two factors that may have contributed to the scale of the disaster. First, as coal plants have gotten better at controlling air pollution, the toxic substances that would have been spewed into the air have been shifted to solid byproducts like fly ash, and the production of such postcombustion waste, as it is called, has increased sharply.

Second, the Kingston plant, surrounded by residential tracts, had little room to grow and simply piled its ash higher and higher, though officials said the pond whose wall gave way was not over capacity.

Environmental groups have long pressed for coal ash to be buried in lined landfills to prevent the leaching of metals into the soil and groundwater, a recommendation borne out by the 2006 E.P.A. report. An above-ground embankment like the one at Kingston was not an appropriate storage site for fly ash, said Thomas J. FitzGerald, the director of nonprofit Kentucky Resources Council and an expert in coal waste.

A reminder from a voice of conscience:

"If we continue to be economically dependent on destroying parts of the Earth, then eventually we will destroy it all."
