Johnsonville Fossil Plant Ash Impoundment Closure Environmental Impact Statement

Humphreys County, Tennessee

On May 26, 2026 the Tennessee Valley Authority (TVA) released the Johnsonville Fossil Plant (JOF) Ash Impoundment Closure Draft Environmental Impact Statement (EIS).

TVA has prepared a draft EIS, pursuant to the National Environmental Policy Act (NEPA), to assess the effects associated with the closure of Ash Pond 2, a CCR surface impoundment at JOF, located in Humphreys County, TN. 

Please see Public Involvement section below for public comment details. Comments on the Draft EIS will be accepted through July 13, 2026.

Alternatives

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

• No Action
• Closure-in-Place of Ash Pond 2
• Closure-by-Removal of Ash Pond 2 to an Existing Offsite Landfill
• Closure-by-Removal to an Onsite or Offsite Beneficial Reuse Processing Facility, with unusable CCR and excavated soil material going to an existing offsite permitted landfill.

Public Scoping

TVA published the Notice of Intent on November 25, 2019. Public comments were accepted through December 20, 2019, concerning both the scope of the review and environmental issues that should be addressed. TVA also hosted a public information session on December 2, 2019, from 5:00 to 7:00 pm at the New Johnsonville City Hall, Safe Room, 319 Long Street, New Johnsonville, Tennessee, and accepted comments at this meeting.

After consideration of comments received during the scoping period, TVA developed a Scoping Report summarizing the public and agency comments that were received. The scoping report was released on March 23, 2020. 

TVA published another Notice of Intent of November 26, 2024. Public comments were invited concerning both the scope of the review and environmental issues that should be addressed through December 30, 2024. 

The comments received during both scoping periods will be considered as the EIS is developed. Additional opportunities for the public to comment on the proposed actions and environmental analysis will be provided during the public review period of the draft EIS.
