Fayette County, Tennessee and Marshall County, Mississippi (Moscow-Miller Project)

Proposed Transmission Project

Update — November 2017

TVA has identified preferred locations for transmission upgrades that would provide power for growing load and increase power reliability in Fayette County in Tennessee and in Marshall County in Mississippi.

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.

TVA’s 17-mile Moscow-Miller Transmission Line would begin at their Hickory Valley-Cordova Tap to Moscow line and extend southwest to the new Chickasaw Trail IP Switching Station. The new Chickasaw Trail IP Switching Station would be located on the corner of Cayce and East Wingo Roads in Byhalia, Mississippi.

The route selected is No. 3 which consists of segment Nos. 1, 2, 4, 7, 12, 17, 18, and 19 as presented at the open house in August 2017.

The new line would consist of steel poles centered on new 100-foot-wide right of way.

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in Fayette County in Tennessee and in Marshall County in Mississippi.

To provide power to the Chickasaw Trail Industrial Park in Olive Branch, Mississippi, TVA proposes to build the approximately 17- to 19-mile Moscow-Miller Transmission Line. This proposed new line would begin at TVA’s Hickory Valley-Cordova Tap to Moscow line and extend southwest 17 to 19 miles to the new Chickasaw Trail IP Switching Station.

The new Moscow-Miller line would be built using steel poles centered on new 100-foot-wide right of way. The line would be built on steel pole, single-circuit structures. There are 8 alternative line routes and 19 alternate line segments under consideration.

The new Chickasaw Trail IP Switching Station would be located on the corner of Cayce and East Wingo Roads in Byhalia, Mississippi.

The new Diffee Switching Station would be located on Diffee Road in Moscow, Tennessee. It would be connected to both the Hickory Valley-Cordova Transmission Line and the tap line.

TVA would rebuild the Cordova-Holly Springs 161-kV Transmission Line which is currently de-energized. The 2.5-mile line would be rebuilt to double-circuit. The existing right of way on this line is 150 feet wide.

TVA would replace overhead ground wire with fiber on the 5.9-mile Hickory Valley-Cordova Tap to Moscow and the 4.4-mile Miller-Olive Branch 161-kV Transmission Lines.

TVA will hold an open house on Thursday, August 10, 2017, to provide information, answer questions and receive comments about the proposed transmission project.

The project is expected to be in service summer 2021. Construction is scheduled to begin summer 2020. (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public involvement

TVA held an open house in August 2017 to discuss the project and answer questions. A 30-day comment period followed the open house.

Map

The map shows the network of alternative routes TVA is considering for the proposed transmission line. The map is also available below as a PDF file.

Environmental reviews

The National Environmental Policy Act review is expected to be completed 2018.

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 along with alternative routes are shown on the referenced map. The map illustrates how each alternative 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.
