Blue Ridge Dam Rehabilitation Project
Fannin County, Georgia
On December 17, 2012, TVA issued a supplemental environmental assessment (EA) and finding of no significant impact (FONSI) for the Blue Ridge Dam Rehabilitation project. The original 2009 EA documented the potential environmental effects of repairing the penstock, repairing and stabilizing the upstream dam face, stabilizing the intake tower base, and repairing and stabilizing the downstream face of the dam.
Due to changes in the project scope that occurred since the preparation of the 2009 EA, TVA issued an initial supplemental EA and FONSI in April, 2011 that documented the potential environmental effects of extending project working hours, establishing a new storage area for rock and soil, and the temporary closure of segments of North River Road during construction.
TVA has recently recognized the need to provide additional stability to the downstream dam face. Consequently, TVA has prepared a second supplemental environmental assessment to document the potential effects of placing additional rock fill along the base of the downstream dam face and extending a buttress wall along the base. Associated actions include the installation of dewatering wells and pumps on the downstream dam face and the construction of an elevated electrical conduit between the powerhouse and the generating unit.
The original 2009 EA and FONSI, the 2011 supplemental EA and FONSI, and the 2012 supplemental EA and FONSI are presented below.
