Environmentalists Say EPA Failed to Defuse ‘Ticking Time Bombs’

Exactly six years ago Christmas eve, thick, highly toxic coal ash washed over hundreds of acres of property and recreational waterways near Kingston, Tenn., in the largest such spill in U.S. history.

A huge dam containing the liquid remains of the coal ash generated by the Kingston Fossil Plant, a Tennessee Valley Authority generating plant about 40 miles west of Knoxville, erupted early in the morning of Dec. 22, 2008. The breach of the eight-story high earthen dam sent a billion gallons of the highly toxic witch’s brew into the nearby Emory River, which feeds into the Clinch River and then the Tennessee River just downstream.

WHY THIS MATTERS

Power plants produce more than 100 million tons of highly toxic coal ash each year. Environmentalists were expecting some strong medicine from the EPA when it finally released new rules for storing that waste to prevent contaminating water supplies. Instead, they were disappointed that EPA seemed to pull its punches last week in issuing new regulations that failed to even classify coal ash as “hazardous” to humans and wildlife.

In all, about 300 acres of waterways and banks were flooded, destroying private homes and fishing and boating facilities and spoiling the natural habitat for great blue herons. Fortunately, no one was killed. But the tidal wave of sludge for all intents and purposes wiped out a vibrant, long-standing community — including the more than 180 homes and properties purchased by the TVA.

The massive, devastating spill prompted the TVA and other utilities throughout the U.S. to reassess how they store coal ash, which is a byproduct of power plants burning coal to generate electricity and is heavily laced with arsenic, mercury and other dangerous or radioactive heavy metals.

The disaster also put pressure on Congress and the Environmental Protection Agency to look more closely at the more than 600 other artificial lakes that were built by utilities throughout the country to hold coal ash.

Last week, the EPA announced that the agency would bring hundreds of coal ash dumps under federal regulations for the first time, according to The Washington Post. Since the 1970s, utility companies for the most part have been exempted from federal waste-disposal regulations and instead have been allowed to dispose of coal ash under state laws, which vary greatly, according to The Washington Post. The conventional process has been to mix the coal ash with water in massive on-site cesspools, which is a lot cheaper than a much safer system of burying the coal ash in a landfill or mine shaft.
