Allen Fossil Plant Emission Control Project

Shelby County, Tennessee

The Tennessee Valley Authority (TVA) is proposing to reduce sulfur dioxide emissions at its Allen Fossil Plant (ALF) in Shelby County, Tennessee. In April 2011, TVA entered into agreements ("EPA Clean Air Agreements") with U.S. Environmental Protection Agency, Alabama, Kentucky, Tennessee, North Carolina, and three environmental advocacy groups. The agreements require TVA to reduce emissions across its coal-fired generating system and take other actions at its coal plants, including retiring some of the units. TVA agreed to reduce emissions at ALF by either installing flue gas desulfurization systems (FGDs or “scrubbers”) or retiring the coal units by December 2018. The existing three coal-fired units at ALF provide both real and reactive power for the Memphis area. To continue to reliably serve the area, generation resources must be located at or near ALF.

To comply with the EPA Clean Air Agreements and continue to provide reliable and affordable power, TVA proposes to replace the existing coal-fired plant by constructing and operating a new natural-gas fired plant.

TVA has prepared a draft environmental assessment (EA) to evaluate the potential environmental effects of implementing the proposed action and alternatives that meet the project purpose and need.

Submitting Comments

Based on the analyses done for the Allen plant decision, TVA has determined that retiring the three coal units and constructing and operating a natural gas plant near the plant would not significantly impact the quality of the human environment. Those analyses and impact determinations are summarized in the draft Environmental Assessment (EA). Although not required, TVA has provided the public 30 days to comment on the draft EA. While this provides the public a reasonable opportunity to comment on TVA’s proposed impact determinations, TVA also is making available for public comment its proposed Finding of No Significant Impact (FONSI). This assumes that TVA will determine in the final EA that impacts are insignificant. Because the EA is the foundation for the FONSI, TVA will consider comments on the EA also to be comments on the FONSI and it is not necessary to resend or restate EA comments. TVA anticipates revising the EA in response to comments it receives and this may require that the FONSI be revised too.

Your comments are invited on the draft EA and draft FONSI, including the alternatives and the environmental resources that were considered. Comments may be submitted online, mailed, or e-mailed no later than August 8, 2014, to Ms. Farless at the address below. Please note that any comments received, including names and addresses, will become part of the project administrative record and will be available for public inspection.

TVA held a public open house on Tuesday, July 8, at Memphis’ Amtrak Central Station Boardroom at 545 South Main Street Memphis, TN 38103 from 3:30 p.m. to 7:30 p.m. The purpose of the open house was to provide information about the draft EA, answer questions, and record comments.

TVA will take all comments into consideration in preparing the final EA. The final EA will be placed on this web site.
