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.
