The U.S. Environmental Protection Agency in Atlanta reported Thursday that monitoring data shows that areas of Watts Bar Reservoir affected by the 2008 ash spill in Kingston have returned to “pre-spill” conditions.

The ash spill occurred at the Tennessee Valley Authority Kingston Fossil Plant. It released 5.4 million cubic yards of coal ash on December 22, 2008.

Environmental data collected from 2009-2015 shows the fish community, benthic macroinvertebrates (bugs), sediment quality, and tree swallow colonies have recovered to baseline conditions that existed before the spill, the EPA said.

The cleanup was accomplished in three phases under the federal Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, commonly known as Superfund. [Read more…]

KINGSTON—The Tennessee Valley Authority has retained J.P. King Auction Company to sell waterfront properties that the public utility bought during the cleanup after the December 2008 ash spill in Kingston.

The properties will be sold at a public auction at 11 a.m. Saturday, July 25, on site rain or shine.

The TVA Board approved the auction company’s proposal to conduct a portfolio auction of 62 properties, up to 19 waterfront properties, four water view homes, and 39 waterfront lots, a press release said. The properties will be sold without reserve at absolute auction, meaning all properties will be sold to the highest bidders, regardless of price, the release said.

Following the 2008 Kingston ash spill, TVA committed to restoring the area to as good as or better than it was before the spill. The first two years of the recovery project required 24/7 operation of heavy equipment on land and in the Emory River. The sounds of the heavy equipment and the lights needed to support night time activities were audible and visible to nearby property owners. Therefore, TVA purchased these properties along Emory River Road, the press release said. [Read more…]

U.S. Environmental Protection Agency guidelines for coal combustion products released on Friday are consistent with work the Tennessee Valley Authority has already done at the Kingston recovery project, the public utility said in a press release.

“TVA is already making substantial changes in the way we work with coal combustion products, including coal ash and gypsum, said TVA President and Chief Executive Officer Bill Johnson. “This included committing an estimated $2 billion to convert all our coal fleet impoundments from wet to dry storage. While recognizing the significant potential for beneficial reuse of ash and other products, we agree it needs to be handled and stored safely.”

The project area surrounding the Kingston Fossil Plant near Harriman is in the final restoration stage following the coal ash spill in December 2008. It was the largest ash spill in U.S. history. [Read more…]

The Tennessee Valley Authority is in the final stages of the Kingston recovery project. The public utility says it’s fulfilling a promise to restore the area surrounding the Kingston Fossil Plant near Harriman following the coal ash spill in December 2008, the largest ash spill in U.S. history.

A major milestone was reached in early December, with the completion of the cover for a 240-acre permanent ash retention landfill. The new landfill, which has been fortified with an underground earthquake-resistant wall anchored in bedrock, is covered by a flexible-membrane liner and geo-composite fabric, two feet of clay, topsoil, and grass.

“We all know this incident shouldn’t have happened,” said TVA President and Chief Executive Officer Bill Johnson, who visited the recovery site on December 17. “But we have learned from it and we are fulfilling our commitment to making it right.”

TVA says it’s also keeping its promise by returning the Emory River and surrounding waterways to pre-spill conditions, reforesting and adding vegetation to surrounding land, stabilizing shorelines, and adding wetlands and other wildlife habitats. TVA has opened Lakeshore Park, which features 32 acres of walking trails, fishing piers, a boat ramp, and docks. [Read more…]

KNOXVILLE—The Tennessee Valley Authority announced Friday that it will pay $27.8 million to settle dozens of lawsuits filed by hundreds of plaintiffs after the largest ash spill in U.S. history.

The 63 lawsuits that had been pending in U.S. District Court in Knoxville involved more than 850 plaintiffs. They had asserted claims against TVA arising from the 2008 ash spill at Kingston Fossil Plant. The lawsuits will be dismissed, bringing the legal battle to an end after more than five years.

The settlement, known as a mediated global resolution, was outlined in documents submitted Friday to the U.S. District Court in Knoxville, a press release said. It comes after nearly two years of mediation ordered by U.S. District Judge Thomas Varlan. The judge must still approve it.

The mediated global resolution has been approved by the TVA board of directors. TVA will pay the $27.8 million to the court clerk to be disbursed to the plaintiffs’ attorneys as ordered by the court, the release said. [Read more…]

KINGSTON—The Tennessee Valley Authority will be building a pedestrian bridge over the East Embayment as part of TVA’s commitment to restore the Swan Pond area near the Kingston Fossil Plant to as good as or better than it was before the 2008 ash spill, a press release said.

For the safety of the public and work crews, access to the East Embayment by boat will be temporarily closed beginning today (Monday), the release said. Signs will be posted on the shoreline and buoys will be installed across the embayment to restrict boating access.

Bank fishing still will be available on the East Embayment and can be reached by walking trails at Lakeshore Park. The main river channel on the Emory River also will remain open. [Read more…]

TVA completes retaining wall, the largest of its kind, at Kingston ash spill

Kingston Ash Spill Retaining Wall

KINGSTON—The Tennessee Valley Authority has achieved a significant milestone in its cleanup of the ash spill at the Kingston Fossil Plant—the completion of an earthquake-resistant, underground retaining wall around the containment cell at the recovery site.

The wall, which completely surrounds the 240-acre containment cell where recovered ash will be permanently stored, was completed on Feb. 20, almost a month ahead of schedule.

“I’m extremely proud of the project team for accomplishing this major undertaking,” said Bob Deacy, TVA senior vice president of projects. “They kept safety at the forefront and completed this significant milestone ahead of schedule.”

Construction of the wall began in summer 2011. Two high-capacity, long-reach hydraulic excavators dug trenches that were 4 feet wide and reached depths between 40 and 70 feet. More than 200,000 tons of cement and other materials were used to construct the wall, which is embedded 70 feet into the bedrock.

It is the largest wall of its kind in the U.S. at nearly 64,000 linear feet, the equivalent of 12 miles, and is designed to withstand a magnitude 6.0 earthquake. [Read more…]

TVA ash spill cleanup continues despite government shutdown

Kingston Fossil Plant Ash Spill Cleanup

Cleanup work at the Kingston Fossil Plant, pictured above, continues despite the federal government shutdown. Workers are cleaning up the largest ash spill in U.S. history. Roughly 5.4 million cubic yards of ash spilled in December 2008 when a storage cell failed.

Work to clean up the ash spill at the Kingston Fossil Plant continues despite the federal government shutdown, a spokesman said Wednesday.

The partial government shutdown shouldn’t affect the Tennessee Valley Authority, which owns and operates the plant, because the public utility doesn’t receive federal funding, spokesman Duncan Mansfield said Wednesday.

Agencies involved in the cleanup project, such as the U.S. Environmental Protection Agency and U.S. Corps of Engineers, have furloughed some workers. But there are still many workers at the Kingston ash spill site, Mansfield said.

“The majority of the work is being performed by contractors,” he said. [Read more…]

Kingston Fossil Plant Ash Spill Cleanup

Ash that spilled into the brown embayment pictured above has been removed, and workers are placing a black liner over an ash containment cell, pictured at center, preparing to close it late next year. More than 5.4 million cubic yards of coal ash spilled in December 2008 when a storage cell used by the Kingston Fossil Plant, back left, failed.

KINGSTON—It was the largest ash spill in U.S. history. A dike failed on a storage cell on a cold December night more than four years ago, and roughly 5.4 million cubic yards of coal ash surged out, covering about 300 acres of land and water near the Kingston Fossil Plant.

No one was injured, but 40 homes in the area were affected. The ash filled three embayments north of the coal-fired plant, covered Swan Pond Road, and flowed into the Emory River. Three homes became uninhabitable because of structural damage.

The work to clean up the gray sludge, which had been four to six feet deep, has been under way since the Dec. 22, 2008, spill. On Friday, officials paused to celebrate two milestones in the six-year, $1.2 billion project. [Read more…]

Information from WYSH Radio

On Thursday, officials from the U.S. Environmental Protection Agency and Tennessee Valley Authority updated Roane County residents on the ongoing cleanup efforts from the 2008 coal ash spill at the Kingston Fossil Plant.

The December 2008 spill dumped more than a billion gallons of coal ash sludge into the Clinch and Emory Rivers and into the surrounding community. What had been 5.4 million cubic yards of sludge is now down to about 70,000 cubic yards—or 14 million gallons—and officials expect to have the rest cleared by the end of June. [Read more…]
