Allen Ash Impoundment Closure

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 the future management of coal combustion residual (CCR) material at the Allen Fossil Plant (ALF) located in Shelby County, Tennessee, southwest of the City of Memphis.

The purpose of this EIS is to support 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 to assist TVA in complying with the Environmental Protection Agency’s (EPA) CCR Rule. In addition, the proposed actions would make the ALF closure area land available for future economic development projects in the greater Memphis area.

TVA will evaluate closure of the East Ash Pond Complex, the West Ash Pond, and the Metal Cleaning Pond. In addition to these closures, TVA will analyze potential location requirements and associated environmental impacts associated with construction and utilization of a proposed beneficial re-use facility to process CCR materials. TVA will also evaluate potential impacts associated with actions requiring use of permitted borrow sites and the disposal of CCR at existing offsite permitted landfills. 

TVA will develop and evaluate various alternatives to 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 4, 2019.

Alternatives

In addition to a No Action Alternative, this EIS will address alternatives that meet the purpose and need for the project. TVA plans to consider the following alternatives:

  • No Action
  • Closure of the Metal Cleaning Pond and closure-by-removal of the East Ash Pond Complex, the West Ash Pond and the CCR surrounding the Metal Cleaning Pond to an offsite landfill location (note that the Metal Cleaning Pond would be removed by default while removing the CCR material surrounding it)
  • Closure of the Metal Cleaning Pond and closure-by-removal of the East Ash Pond Complex, the West Ash Pond and the CCR surrounding the Metal Cleaning Pond to a beneficial re-use facility & offsite landfill location (note that the Metal Cleaning Pond would be removed by default while removing the CCR material surrounding it)
  • Closure of the Metal Cleaning Pond and closure-in-place of all CCR in the East Ash Pond Complex, the West Ash Pond and CCR surrounding the Metal Cleaning Pond.

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 November 30, 2018 to January 4, 2019 in one of three ways:

  • Mail to Ashley Farless, NEPA Compliance Specialist, 1101 Market Street, BR4A-C, Chattanooga, TN, 37402.
  • Email to arfarless@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 final disposal of CCR and closure of the surface impoundments 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, and financial considerations.

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