Yesterday the EPA performed a turn-around on its protection of the locations of 44 “high risk” coal ash impoundment sites, signaling a desire to make the regulatory body more transparent.
Formerly protected under the auspices of national security, the ash impoundments, located in Ohio, Arizona, and throughout the southeast, have been determined to be particularly vulnerable to failure. In a time where the future of American energy remains stuck between antiquated fossil fuels and cleaner, renewable technology, concerns over proper disposal of coal ash has risen to the top of the debate, particularly after last December’s TVA sludge disaster in Roane County, Tennessee.
The reason behind this concern is, of course, fairly easy to identify. Coal slurry ponds, which may hold several billion gallons of the toxic sludge, are typically held in place by earthen dams made of rock and other fill material. While typically sturdy, history has shown us that these dams are definitely prone to failure, especially when not regulated properly. In fact, the dangers surrounding slurry dams have been well known and well documented for decades. West Virginia’s Buffalo Creek Flood of 1972 destroyed over 500 homes with a 30-foot high, 132 million gallon wave of the toxic stuff. When blasting occurs near these ponds (as it does near Marsh Fork Elmentary in Sunrise, WV), the risk becomes intensified as nearby shockwaves may threaten the structural integrity of the dam.
Fly ash, though dry and therefore less at risk to flooding, presents just as serious a hazard to the local ecosystem, including surrounding communities, wildlife, and groundwater reserves. Fly ash is stored in landfills, most of which are lined, but all of which are failure-prone. Particles in the air, blown from these ash impoundments, can cause serious health problems such as asthma and other respiratory diseases. Like wet slurry, fly ash contains a cocktail of harmful heavy metals and other contaminants that present a serious threat to the local and regional ecosystem… and to human health.
“CCRs [coal combustion residues] contain a broad range of metals, for example, arsenic, selenium, cadmium, lead, and mercury, but the concentrations of these are generally low. However, if not properly managed, (for example, in lined units), CCRs may cause a risk to human health and the environment and, in fact, EPA has documented cases of environmental damage“ (courtesy EPA.gov).
The collection and storage of coal ash is but one piece in a larger fossil fuel regime that thrives on the continued exploitation of the United States’ natural, non-renewable resources, known to cause significant air pollution and contribute to global climate change. The coal extraction, combustion, and disposal process is among the most destructive practices in human history, and with the continued popularity of mountaintop removal mining, the coal industry goes so far as to threaten the geography of Appalachia itself.
The EPA has made positive steps in naming these so-called high-risk sites, but seems to be avoiding tackling the bigger picture; coal is an unsustainable resource that is dirty, harmful, and dangerous. While 44 of these impoundment sites may be deemed more at-risk than others, the fact remains that anywhere coal is extracted, burned, or stored, safety is a non-issue, because coal is not, and never will be, “safe.”
President Obama, who has so far struggled with fulfilling his promise of increased transparency and accountability within government, has made significant forward progress by allowing the release of these 44 sites. However, the larger issue of formulating an American energy future – one without coal – rests untackled. As long as coal is allowed to thrive in Appalachia, the Midwest, and elsewhere, American citizens will remain at risk. The fossil fuel industry represents an old and outdated way of thinking: the idea that our actions now will bear no consequence on the future. We have now stepped healthily into the 21st century, largely thankful to the energy that fossil fuels of yore have given us, and as we continue to evolve as a species and a society, we are charged with abandoning a tradition that will serve no other end but to continue to harm Americans.
To President, Obama, Congress, and the EPA, if we are to bring the United States into a clean energy future, one that emphasizes the importance of renewable technologies, green jobs, and energy that is free of filthy, harmful substances, then we must see a real effort to focus on goals that do not give coal a future in the grid. The EPA seems to think that the term, “high risk,” should be reserved for a mere 44 out of the hundreds of slurry ponds and fly ash fills that sprinkle the American landscape. A more appropriate move would be to extend the “high risk” moniker to its proper breadth, across the entire industry.
