City of Sevierville Revised Finished Waterline Installation Plans
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). On October 25, 2005, TVA signed a third FONSI reevaluating the environmental effects of constructing a 1,200-foot temporary rock-filled construction pad in the river and conducting some shoreline stabilization in the vicinity of the project (see sidebar link to third FONSI).
As intake and water treatment plant construction has progressed and finished water distribution plans have been finalized, in January 2006, SWS proposed an additional change in the route of the finished water-main pipelines from the water treatment plant to connection points (see FONSI by clicking on the link below). SWS believes the additional 36-inch water main river crossing from the water treatment plant would allow it to better serve its customers by providing a second source of treated water to the system. Installed at a lower elevation, it is expected that this alignment would require lower head pumps.
The cost of installation is expected to be reduced because the City of Sevierville (City) owns the easement along the existing 24- inch sewer line. This route would also allow SWS to connect to the existing City system near the location of future road improvements and anticipated commercial development expansion along Highway 66. This location, which would cross the back channel of the French Broad River from McCroskey Island at approximate Mile 27.3, is also expected to potentially reduce probable conflicts with archaeological resources.
Aquatic species, their habitats, and archaeological resource effects of this proposed project change are included in this reevaluation. All of the previous TVA FONSIs will remain valid.
