Allen Fossil Plant Decontamination and Deconstruction Environmental Assessment
Shelby County, Tennessee
On October 4, 2019, TVA issued a Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for decontamination and deconstruction of its Allen Fossil Plant in Shelby County, Tennessee. The EA evaluates the potential environmental effects of the future disposition of the physical structures assocated with the retired coal-fired plant units, including the powerhouse, coal handling facilities, and surrounding support buildings. TVA needs to manage the disposition of the ALF site to provide necessary structures and facilities for ongoing site activities while considering capital cost, long-term operations and maintenance costs, environmental risks, safety and security at the plant site, and making the land available for future economic development.
TVA evaluated four alternatives: Alternative D is Full Demolition to Grade Resulting in a Brownfield Site with Stack Removal Options D1, D2, and D3. Alternative D1 includes drop removal of stacks and structures. Alternative D1 includes mechanical removal of stacks and structures. Alternative D3 includes hybrid removal of stacks and structures. Alternative E is to take no action. TVA’s preferred alternative is Alternative D1, D2, or D3, full demolition to grade resulting in a brownfield site. TVA concluded that implementing Alternative D1, D2, or D3 would not be a major federal action sigifnicantly affecting the environment. Therefore, TVA has issued the FONSI.
The Draft EA was released for comment on May 31, 2019. The 30-day comment period closed on July 1, 2019. The Draft EA was transmitted to state, federal, and local agencies and TVA consulted with federally recognized tribes regarding the project actions. The Draft EA was also posted on TVA’s public NEPA review website. A notice of availability, including a request for comments on the Draft EA, was published in newspapers serving the Shelby County, Tennessee area. Comments on the Draft EA were accepted for 30-days, through July 1, 2019, via TVA’s website, mail, and e-mail. TVA carefully reviewed all of the substantative comments that it received. Comments were summarized and included in Appendix A of the Final EA.
