Gallatin Surface Impoundment Closure and Restoration Project

Sumner County, Tennessee

Environmental Impact Statement

The Tennessee Valley Authority (TVA) is preparing an Environmental Impact Statement (EIS) to address the potential environmental effects associated with management of coal combustion residuals (CCR) material at the Gallatin Fossil Plant (GAF) located near Gallatin, Sumner County, Tennessee.

This project addresses the disposition of CCR onsite at GAF, supports the implementation of TVA’s goal to eliminate all wet CCR storage at its coal plants by closing CCR surface impoundments across the TVA system, and assists TVA in complying with EPA’s CCR Rule and other applicable federal and state statutes and regulations.

Alternatives

The EIS examines the following alternatives:

  • Alternative A – No Action Alternative
  • Alternative B – Closure of the Ash Pond Complex (APC) via Closure-by-Removal and Expansion of the Existing Onsite Landfill

Under alternative B, TVA is considering two options for disposal of CCR removed from the APC  Under Option 1, CCR removed from surface impoundments would be transported via onsite haul roads and placed in either the existing onsite landfill, an expansion of the existing landfill, or a combination of these landfills. Under Option 2, instead of transporting excavated CCR material to an onsite landfill, CCR would be transported to an offsite beneficial re-use processing facility to be processed for use in concrete and other marketable materials. Under Option 2, some of the CCR may be unusable for beneficial re-use and would be disposed of in either the onsite landfill or transported to an existing offsite landfill previously permitted to receive CCR.

No decision has been made about CCR storage at GAF beyond the current operations. TVA is preparing this EIS to inform decision makers, other agencies and the public about the potential for environmental impacts associated with management of CCR at GAF.

Background and Previous Public Involvement

A Notice of Intent to prepare an EIS was published to the Federal Register on December 7, 2018.  Public comments on the scope of the EIS were collected through January 11, 2019. After consideration of comments received during the scoping period, TVA developed a Scoping Report that summarized public and agency comments that were received and identified the schedule for completing the EIS process.  The scoping report was released in April 2019. 

TVA released the draft EIS for public review on December 27, 2019. A Notice of Availability for the draft EIS was published in the Federal Register on January 4, 2020. A public information session was held on January 16, 2020 at the Gallatin Civil Center in Gallatin, Tennessee, to allow the public the opportunity to learn more about the project.  Public comments were accepted between December 27, 2019 and February 18, 2020, and at the public information session. TVA is reviewing the comments received on the draft during the comment period and will incorporate them into the final document. The Final EIS is anticipated to be released in the summer of 2020.
