The Environmental Protection Agency released long-awaited coal ash regulations today, the first rules ever to be imposed on the storage and disposal of the toxic waste left over after burning coal for electricity—the second largest industrial waste stream in the U.S.
But according to Earthjustice and the 10 environmental and public interest groups it represented in suing to force the release of the regulations in the first place, the EPA’s new rules are not nearly stringent enough to stop the next coal ash spill before it happens.
The new rules will not phase out the practice of storing massive quantities of coal ash—which contains highly toxic substances like arsenic, mercury, lead and radioactive uranium—in unlined ponds shored up by earthen dams that are often unstable and likely to fail. This is exactly what happened in the case of the Dan River coal ash spill in North Carolina this past February and the spill in Kingston, Tennessee in 2008 that released 1.1 billion gallons of coal fly ash slurry, covering up to 300 acres of surrounding land.
The typical coal ash dam is built from soil and ash and is used to impound millions of tons of coal ash and wastewater. The majority are over 40 years old, according to Earthjustice, and most do not have monitoring systems in place for detecting leaks of the toxic coal ash slurry they contain.
