The TVA recently completed a 12-mile, four-foot-wide underground retaining wall to surround 240 acres of toxic coal ash. The wall was needed in December 2008, when a dike at TVA's Kingston Fossil Plant failed, sending sent 5.4 million cubic yards of coal ash into the Emory and Clinch rivers, polluting the water, destroying three homes and damaging dozens of other homes.
