City of Sevierville Revised Intake Installation Reevaluation


In February 2005, TVA completed a Finding of No Significant Impact (FONSI) for Section 26a approval of the proposed Sevierville Water Systems (SWS) intake and water treatment plant at French Broad River Mile 27.5 (see original project summary). On February 4, TVA also issued its conditional Section 26a permit. In April, Aquarius Marine, Inc., on behalf of SWS (subcontractor to the primary contractor, W. Rogers Company), presented a proposal to TVA, in connection with the approved intake installation, to rent an upstream piece of private land for use as a staging and launch area at approximate FBRM 27.9 (see sidebar link to second FONSI).

Because of varying Douglas Reservoir discharge volumes, resultant fluctuating water levels, and the need to keep work barges (construction, equipment, and temporary spoil storage) afloat on the French Broad River (Douglas Dam tailwater), SWS has been unable to make substantial progress installing the approved 1,600 feet of 36-inch diameter ductile iron pipe and intake this summer. Requested by W. Roger Company, on behalf of SWS, this reevaluation examines the potential cultural and aquatic ecological impacts of constructing a 1200-foot temporary rock construction work pad in the French Broad River to facilitate installing the intake. A design feature includes an approximate 130-foot bridge from the shore to the rock pad to allow flows from the Little Pigeon River and fish passage (see attachments to this FONSI). In addition, this reevaluation considers SWS’s request to construct additional shoreline armoring (riprap) in the vicinity of the approved water treatment plant location. Also, as a result of the project, TVA anticipates a shoreline landowner on the opposite bank (right descending) to request refurbishment of rock material, either shot rock from the riverbed trench or rock from the temporary construction pad, along a portion of the his shore. This would allow SWS to use excess rock for a beneficial purpose instead of hauling it to an upland site. Effects of this shoreline stabilization work are also included in this reevaluation. Both the previous TVA FONSIs will remain valid.
