Fayette County, Tennessee and DeSoto and Marshall Counties, Mississippi
On October 16, 2019, TVA issued a Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for the proposal to improve the existing power supply in both Fayette County, Tennessee (TN) and DeSoto and Marshall Counties, Mississippi (MS). This EA addressed the proposed actions taken by TVA to construct, operate and maintain two switching stations (Chickasaw Trails Industrial Park 161-kV Switching Station and Diffee 161-kV Switching Station), an 18.5 mile Diffee-Chickasaw Trails Industrial Park 161-kV Transmission Line (TL) and associated 161-kV loop TLs, rebuild 2.5 miles of double-circuit 161-kV TL, as well as the addition of Fiber Optic Groundwire (OPGW) to the existing TVA transmission system.
Pursuant to the National Environmental Policy Act of 1969 (NEPA) and the Act’s implementing regulations promulgated by the Council on Environmental Quality ([CEQ]; 40 Code of Federal Regulations [CFR] 1500-1508), federal agencies are required to evaluate the potential environmental impacts of their proposed actions. This EA was prepared to assess the potential impacts of TVA’s Proposed Action on the environment in accordance with CEQ’s and TVA’s procedures for implementing NEPA (TVA 1983).
The EA studied two alternatives: (1) the No Action alternative which TVA would not provide a new power supply to Fayette County, TN and DeSoto and Marshall Counties, MS, and (2) the Action Alternative which TVA would provide a new power supply to Fayette County, TN and DeSoto and Marshall Counties, MS.
