Tennessee Valley Authority November 15, 2019 – Federal Register Recent Federal Regulation Documents

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 residuals (CCR) material at the Johnsonville Fossil Plant (JOF) located in Humphreys County, Tennessee. The purpose of this EIS is to address the disposition of Ash Pond 2 at JOF, 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 United States Environmental Protection Agency (EPA) CCR Rule and other applicable federal and state statutes and regulations. TVA will evaluate the closure of JOF Ash Pond 2 and will develop and evaluate various alternatives for closure including the No Action Alternative. One alternative identified by TVA is Closure-in-Place of Ash Pond 2. Another alternative is Closure-by- Removal of Ash Pond 2. TVA is considering four options for disposal of the CCR removed from Ash Pond 2, including transport and disposal of CCR in an existing offsite permitted landfill, transport and disposal of CCR to a new onsite landfill, transport and disposal of CCR to both an existing offsite permitted landfill and a new onsite landfill, and transport of CCR to a beneficial re-use processing facility to be processed for use in concrete and other building materials with any unusable CCR and excavated soil material going to an existing offsite or new onsite permitted landfill. TVA has identified a potential location for a new onsite landfill. TVA has not selected a potential offsite landfill for disposal of CCR from JOF, and no specific provider of the beneficiation services or specific site at which a beneficial re-use processing facility would be constructed has been developed at this time. Therefore, impacts of these options for CCR disposal would be based on the most impactful or ``bounding'' characteristics of CCR transport to suitable existing landfills or to a beneficial re-use processing facility. Similarly, the potential effects of construction and operation of the beneficial re- use processing facility will be evaluated using `bounding'' attributes obtained from candidate beneficiation vendors. Public comments are invited concerning both the scope of the review and environmental issues that should be addressed. No decisions have been made about the final disposition of CCR storage at COF Ash Pond 2.
