Olive Branch, Mississippi (Mineral Wells-West Pleasant Hill)

Update – February 2019

TVA has identified the preferred route for a new transmission line that would provide power for growing load and increase power reliability in the Olive Branch area.  TVA’s new line would provide an alternate power supply to Northcentral Electric Power Association’s (EPA’s) Mineral Wells Substation in Olive Branch.  

TVA evaluated each route using social, engineering and environmental factors.  Information sources included available data, aerial photography, limited onsite reviews, public review and comment and property owner input.  Based on public input and evaluation, the preferred route is expected to have the least overall project impacts of the alternatives.

The 5.03-mile line would begin at TVA’s Freeport-Miller 161-kV Transmission Line-Tap to West Pleasant Hill Substation and extend northeast to Northcentral EPA’s Mineral Wells Substation off Highway 78.  TVA would build 3.3 miles of single-circuit and rebuild as double-circuit 1.73 miles of 161-kV transmission line.  The 3.3-mile new line would consist of single-circuit, steel pole structures centered on new 100-foot-wide right of way.  The 1.73-mile rebuild portion would be on double-circuit, steel pole structures on existing right of way adjacent to railroad right of way.  

The route selected is No. 1 consisting of segment Nos. 1, 3, 4, 7, 8 and 10 as presented at the open house in October 2018.

Public Involvement

TVA held an open house in October 2018 to discuss the project and answer questions. A 30-day comment period followed the open house.

Environmental Reviews

The appropriate National Environmental Policy Act review will be conducted to ensure that the environmental impacts are minimized. TVA attempts to minimize any land requirements, private property impacts, and environmental impacts associated with this project.

Efforts are made during the siting process to avoid or minimize impacts to floodplains and wetlands in accordance with Executive Orders 11988 and 11990. Floodplains and wetlands are shown on the referenced map. The map illustrates how the route avoids or impacts floodplains and wetlands. Because of project and topographic constraints and because of minimizing impacts to other social, environmental, and engineering resources, no practicable alternative may be available that would allow complete avoidance of impacts to floodplains and wetlands which may require mitigation for minimizing impacts. Also, best management practices would be utilized throughout the project to minimize adverse floodplain and wetland impacts. In compliance with Section 404 of the Clean Water Act, TVA will be coordinating wetland findings with U.S. Army Corps of Engineers.
