The Knoxville News Sentinel reported that, with the removal of a final pile of gray ash on Friday, the $1.1 billion removal of spilled ash will conclude.
TVA must still monitor layers of ash on the bottom of the Emory and Clinch rivers for 30 years. It was agreed that allowing the streams to naturally bury the ash under layers of sediment was the best solution for the underwater sludge.
It was on a frigid early morning on Dec. 22, 2008 that a containment cell at the Kingston Fossil Plant failed and some 5.4 million cubic yards of coal ash spread in what a local resident called an 8-foot-tall tsunami.
