Gallatin Surface Impoundment Closure and Restoration Project

Environmental Impact Statement

Notice of Intent (NOI) and Public Scoping

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

The purpose of the EIS is to address the final disposition of CCR onsite at GAF, support TVA’s goal to eliminate wet CCR storage at its plants, and assist TVA in complying with the U.S. Environmental Protection Agency (EPA’s) CCR Rule. The proposed actions would also provide long-term on-site landfill space for operations and/or storage of CCR. TVA will develop and evaluate various alternatives for these actions, including the No Action Alternative.

Public comments are invited concerning both the scope of the review and environmental issues that should be addressed. Comments on the scope of the EIS must be received on or before January 11, 2019.

Alternatives

The EIS will examine closure of the following surface impoundments: Ash Pond A, Ash Pond E, Middle Pond A and a Non-Registered Site. In addition, TVA will examine removal of CCR from on-site Stilling Ponds and permanent disposition of CCR from the Bottom Ash Pond at Gallatin. TVA is performing a separate NEPA review for a project at Gallatin that could result in a temporary stockpile of CCR from the Bottom Ash Pond in the on-site landfill (North Rail Loop Landfill). The Bottom Ash Pond CCR would be temporarily stockpiled to make the most efficient use of property at GAF. Whether the Bottom Ash Pond CCR remains in its current location onsite at GAF or is temporarily stockpiled to allow TVA to make use of real estate available onsite, the final disposition of the Bottom Ash Pond CCR will be addressed in this EIS. Construction of a new on-site landfill will be examined as well as construction of a CCR beneficial re-use facility.

In addition to a No Action Alternative, this EIS will address alternatives that meet the purpose and need for the project. One alternative identified by TVA is closure of all surface impoundments and stilling ponds via closure-by-removal with construction of a new on-site landfill. CCR material removed in this closure-by-removal alternative would be disposed of in a new on-site landfill and/or a beneficial re-use facility. Another alternative identified by TVA is closure of all surface impoundments and stilling ponds via closure-in-place with construction of a new on-site landfill that would be used to support ongoing long-term plant operations. TVA could also consider a combination closure-in-place and closure-by-removal alternative(s).

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.

Comments

TVA is interested in an open process and wants input from the community. The public is invited to submit comments on the scope of this EIS from December 7, 2018 to January 11, 2019 in one of three ways:

  • Mail to Ashley Farless, NEPA Compliance Specialist, 1101 Market Street, BR4A-C, Chattanooga, TN, 37402.
  • Email to CCR@tva.gov.
  • Submit online.

Next Steps

After consideration of comments received during the scoping period, TVA will develop and distribute a scoping document that will summarize public and agency comments that were received and identify the schedule for completing the EIS process. Following analysis of the issues, TVA will prepare a draft EIS for public review and comment. In making its final decision, TVA will consider the analyses in this EIS and substantive comments that it receives.

A final decision on proceeding with the management and storage of CCRs at GAF will depend on a number of factors. These include results of the EIS, requirements of the CCR Rule, relevant state law requirements, engineering and risk evaluations, financial considerations, as well as the resolution of ongoing litigation concerning Gallatin.

TVA anticipates holding a community meeting near the plant after releasing the Draft EIS. Meeting details will be posted on TVA’s website. TVA expects to release the Draft EIS in the Fall 2019.
