Fort Loudoun Dredge Reevaluations
On October 25, 2004, Environmental Policy and Planning, NEPA Administration, signed separate FONSIs for proposed channel maintenance dredging at Looney Island, at Tennessee River Mile 643.0, and at Post Oak Island, at TRM 631.8. The proposed dredging sites would be located about five miles and 16 miles, respectively, downstream of downtown Knoxville.
In November 2004, the U.S. Army Corps of Engineers (USACE) requested that the dredging work be allowed to commence during the early summer rather than restricting dredging to fall as originally planned and described in the original FONSIs. This reevaluation considers potential effects of dredging on aquatic life to complete activities at both the Looney and Post Oak Island sites. Summertime reservoir elevations and water volume as well as more likely favorable working conditions to reduce the length of time needed to complete the projects would reduce biological exposure to and potential uptake of sediment contaminants.
Because the dredged spoil material is being redistributed on the reservoir bottom and could pose an obstruction, TVA issues its conditional Section 26a permit for these projects on October 28, 2004. These permits and the original TVA FONSIs remain valid. USACE has scheduled the dredge work (over four to eight weeks) to begin in mid-June 2005.
