TVA Plans for Permanent System to Manage Water Flows at Gallatin

January 10, 2020

KNOXVILLE, Tenn.­­ – The Tennessee Valley Authority is planning to turn a temporary solution to manage water flows from processes at Gallatin Fossil Plant into a permanent system.

Details of the preferred alternative are available in a final Supplemental Environmental Assessment posted at www.tva.com/nepa. The preferred alternative is to continue operation of an interim flow management system on a permanent basis, with modifications, rather than build new process water basins.

As TVA has progressed with the interim flow management system, TVA has learned that these tank systems are an efficient and effective way to treat process water flows to maintain compliance with permit limits. The system would be connected to a bottom ash dewatering facility once construction on that plant is completed. The resulting dry bottom ash would be stored in the approved onsite landfill.

The project supports TVA’s commitment to convert to dry storage of coal combustion residuals at Gallatin and across the system, as well as a consent agreement with the state to close and remove ash stored at Gallatin. That agreement is subject to a separate environmental review, currently under way and available at www.tva.com/nepa.
