Ep. 001: Cleaning up the largest industrial disaster in US history

Over a billion gallons of coal ash sludge, hundreds of sick workers, and a disaster most Americans have never heard of.

In the early hours of a December morning in 2008, three days before Christmas, a 60-foot dike gave way at the Tennessee Valley Authority's Kingston Fossil Plant. Over a billion gallons of coal ash slurry — enough to fill 1,500 Niagara Falls — surged into the Emory River, covering 300 acres of East Tennessee under a wave of black soot. Homes were pushed off their foundations. One resident, asleep at the time, woke to find his house sitting in the middle of the road on top of coal ash.

It was, and remains, the largest industrial disaster in United States history. Nearly two decades later, most Americans have never heard of it.

Episode 1 of Talking Trash returns to Kingston to ask why — and to trace how a disaster of that scale could vanish from the national conversation while the workers who cleaned it up kept getting sicker, and dying.

What happened at Kingston

The coal ash pond behind TVA's Kingston plant had been accumulating waste since the 1950s. According to Wes Bunch, a former journalist and lifelong resident of the neighborhood, the pond had been leaking for years before the collapse — coal slurry running into the road after heavy rains. It had already suffered a smaller collapse two years earlier. Ansol Clark, who would later die of a rare blood cancer, had helped patch it.

When the dike finally gave way, 900 workers descended on the site from across the country. Many were told the coal ash was safe. One safety officer, according to journalist Jared Sullivan, told the workers directly: "I wouldn't be out here if I thought it was hazardous. I have a wife and family too, trust me on this."

Within months, they began coughing up a black, jellylike substance they called "the Kingston Crud." Then came the blackouts and heart failures. By 2013, they had a lawyer, and in 2018, a federal jury found that Jacobs had failed to protect them. It took another five years for the lawsuit to settle. As of July 2026, more than 60 of the workers are dead.

Three systemic failures we discuss

1. Coal ash has never been meaningfully regulated

Coal ash carries arsenic, mercury, lead, radium, and cadmium — any one of which, in most other contexts, would trigger the strictest tier of federal hazardous waste rules. But coal ash is regulated under the federal law that covers non-hazardous solid waste — the same category as municipal trash. (When Congress passed its hazardous waste regulation in 1976, coal was spared through a special exception.)

New 2015 EPA rules, formed in the wake of Kingston, required power companies to monitor active dump sites for groundwater contamination. But they didn't touch the roughly 375 inactive sites across the country, or the underlying classification. The Biden administration extended these rules to inactive sites in 2024, but the Trump administration has pushed those cleanup deadlines into the 2030s.

The industry has profited from this ambiguity for decades. So long as coal ash sits outside the hazardous-waste framework, power companies can store it in unlined pits, sell it into consumer markets, and avoid the reporting requirements that would make the true scale of the problem visible.

2. There’s money in coal ash that industry can’t quit

Roughly half of the coal ash produced in the US every year — about 64 million tons — gets resold. It ends up in concrete, wallboard, roof tiles, road base, paint, cosmetics, and bowling balls. The global coal ash market is estimated at $7–$15 billion annually.

The Kingston cleanup site was officially known as "the Kingston Recovery Project" — because part of the work involved sifting the ash for saleable material: rare earth minerals, and tiny floating silica beads called cenospheres. TVA's CEO told a public meeting that recovering cenospheres from the river was a top priority. Restoring residents' properties, or protecting cleanup workers, was not.

As Dr. Lisa East, an environmental sociologist at UT-Knoxville, put it: "These are the technological gymnastics industries do to attempt to continue the lifecycle of fossil fuels." If coal ash was once a blight, it has since become a stable byproduct the industry has figured out how to profit from twice.

3. The “debate” over coal is largely manufactured

Lisa's research focuses on how the coal industry talks about itself; her master's thesis covered the "clean coal" PR campaign and the trade group behind it. In her classroom at UT-Knoxville, where many students have direct family ties to the cleanup, she rarely encounters students arguing for "the beauty of clean coal technology."

That's because, she argues, the polarized public debate we see on cable news doesn't reflect how most people actually think about coal. In the coal-dependent communities she's visited, people want a different future too — one where their relatives don't get sick from work, where their children can fish the rivers they grew up in.
