What is TVA doing now to repair the site?
• An important step in the recovery of the Kingston site is Phase I dredging to remove ash from the Emory River channel. TVA’s Phase I dredging plan was submitted to TDEC and EP A and approved by both agencies on March 19, 2009. A pilot study was conducted during Phase I dredging to determine the processing capacity for full-scale dredging, how the ash would move during the process, and the effectiveness of TVA’s dredging strategies. Dredging officially began on March 19, and more than 156,000 cubic yards of ash have been removed from the Emory River as of mid-May. The primary equipment used in the dredging process is hydraulic dredges. Mechanical clamshells are also being used to remove debris from the water. Both types of equipment are being operated in a way that minimizes water turbidity, or cloudiness. Continuous water quality monitoring and routine water sampling and analyses will continue to be conducted throughout the dredging process. • TVA has coordinated efforts with the Roa
