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…]

Kingston Fossil Plant Ash Spill Cleanup

Ash that spilled into the brown embayment pictured above had been removed by June 2013, and workers placed a black plastic liner over an ash containment cell in the background, preparing to close it. The ash spilled in December 2008 when a storage cell failed at the Kingston Fossil Plant, back left.

 

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 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…]

TVA will use natural river processes for ash from Kingston spill

The Tennessee Valley Authority will rely on natural river processes and long-term monitoring to take care of ash in the Clinch and lower Emory rivers as part of the recovery from the 2008 coal ash spill at the Kingston Fossil Plant, a press release said.

The process, known as Monitored Natural Recovery, was the preferred option among several alternatives proposed to manage an estimated 500,000 cubic yards of remaining ash dispersed intermittently over more than 200 acres in the river system, the release said.

The alternatives were proposed in an Engineering Evaluation and Cost Analysis, which was released for public review and comment in August.

Here is more information from the press release:

TVA’s selection of Monitored Natural Recovery, also called EE/CA Alternative 1, is documented in an Action Memorandum released by the agency. It is based on extensive research, including human health and ecological risk assessments, and aligns with the majority of public comments received on the EE/CA alternatives.

The selection was also approved by the U.S. Environmental Protection Agency and the Tennessee Department of Environment and Conservation.

Monitored Natural Recovery avoids disturbing legacy contaminants from past U.S. Department of Energy projects in the river system, provides the best balance with respect to effectiveness and implementation, and is the most cost-effective option for consumers of TVA power.

The release said the Action Memorandum has been posted to the Administrative Record for the Kingston Ash Recovery Project at www.tva.com/kingston. It also is available for review at the Kingston and Harriman public libraries.

TVA has encouraged the public to review and comment on the Action Memorandum from Nov. 9 through Dec. 8. Pertinent comments and their responses will be included in a Responsiveness Summary document and placed in the Administrative Record.

The Tennessee Valley Authority is a corporation owned by the U.S. government, and it provides electricity for nine million people in parts of seven southeastern states. TVA also provides flood control, navigation and land management for the Tennessee River system and assists utilities and state and local governments with economic development.
