TVA Completes Ash Excavation at Kingston Recovery Site
June 28, 2013
KNOXVILLE, Tenn. – The Tennessee Valley Authority is marking two significant milestones in the Kingston Recovery Project with the completion of ash excavation around the storage cell that failed in December 2008 and the placement of a liner over the failed cell.
"These are major steps toward our goal of restoring the area to a condition that is as good as or better than it was before the spill," said Bob Deacy, TVA senior vice president of Generation Construction.
Workers have removed more than 3 million cubic yards of ash from the middle embayment and areas north of the cell using excavating equipment. The ash will be covered and permanently stored on site, surrounded by an earthquake-resistant, reinforced wall tied into bedrock up to 70 feet deep one of the largest walls of its type ever constructed in the United States. Work on that structure should be finished this fall.
Workers are placing a liner over the containment cell — a significant step in the process of closing it by late 2014. The first section of the liner is already in place on a segment of the cell.
"It really is a light at the end of the tunnel," said Craig Zeller, project manager for the Environmental Protection Agency at Kingston. "Now we can focus more on long-term monitoring and other aspects of the project."
TVA has implemented a long-term monitoring plan to continue to assess the ecological health of the river system.
Work also is under way on public recreation areas, which will include fishing piers, walking trails and green space around the former Lakeshore Drive area and the middle and north embayments.
The entire Kingston Recovery Project is expected to be completed by early 2015.
"We still have a lot of work to do, but our employees and contractors can be proud of their efforts so far," Deacy said. "A tremendous amount of credit goes to the hundreds of skilled trades and labor workers who bring a wealth of experience and skills to the job."
