TVA is inviting public comment on the draft Supplemental Environmental Assessment (SEA) associated with this project.

Update October 2014
TVA has evaluated several options for a new transmission line that will provide proposed power line easements to support industrial development in the Memphis Regional Megasite near Stanton, Tennessee. The proposed power line easements, funded under an agreement with the State of Tennessee, are in Fayette and Haywood Counties.
The same considerations — environmental, engineering, and social — were used to assess each alternative. The reviews were based on available data, aerial photography, onsite reviews, public review and comment, and property owners' input. Based on these evaluations, TVA has identified alternative route segments 1, 4, 9, 10, 12, 14, 18, and 20 as the preferred route (see map).
The proposed easements would allow power to the proposed Memphis Regional Megasite utilizing either 500-kV power via the Haywood Switching Station-Cordova 500-kV Transmission Line or 161-kV power via the Cordova-South Jackson 161-kV Transmission Line. The proposed easement would be 100 feet wide between the Cordova-South Jackson 161-kV Transmission Line and the Haywood Switching Station-Cordova 500-kV Transmission Line and 300 feet wide from the Haywood Switching Station-Cordova 500-kV Transmission Line to the Memphis Regional Megasite location. This combination of easement widths will allow flexibility to provide whatever power is needed for the Megasite in a shorter timeframe, making it more attractive to potential industrial customers.
At this time, TVA is tentatively scheduled to conduct field surveys for the proposed easements in winter 2014-2015 and begin buying right-of-way in summer 2015.
In keeping with TVA's environmental stewardship, appropriate National Environmental Policy Act review will be conducted.
TVA is considering transmission line routes that will provide power to the new Memphis Regional Megasite, located in Haywood County.
Through a project funded by the State of Tennessee, TVA is identifying possible transmission routes from existing lines to the megasite. Depending on the electrical needs of industry locating at the megasite, new transmission lines from either TVA’s existing South Jackson-Cordova 161-kilovolt Transmission Line or the Lagoon Creek-Cordova 500-kilovolt Transmission Line would be identified for construction.
TVA will hold an open house on April 24, 2014 to provide
information, answer questions and receive comments about the proposed
transmission line routes.
TVA's process for siting new transmission projects is designed to allow public input at various stages. TVA is committed to working with area stakeholders to address concerns during the course of the project. Comments received during the comment period will be used in reaching a decision on the proposed action.
TVA will hold an open house to discuss the proposed transmission project. Details are as follows:
Thursday, April 24, 2014
Anytime between 3:00 - 7:00 p.m. CDT
Old National Guard Armory
100 Boyd Avenue
Brownsville, Tennessee 38012
TVA representatives will be available at the open house to provide information, answer questions and receive comments. Large maps showing the alternative transmission line routes being considered for the project will be available.
TVA is interested in receiving comments concerning how this project may affect the environment, historic properties or any other issues associated with this proposal. Any comments received, including names and addresses, will become part of the administrative record and will be available for public inspection. All written comments on this proposed action should be sent to TVA no later than May 26, 2014.
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.
