Management of Coal Combustion Residuals from the Paradise Fossil Plant

On June 8, 2017, TVA issued a Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) on the Management of Coal Combustion Residuals (CCR) at the Paradise Fossil Plant. The plant is located in western Kentucky on the Green River in Muhlenberg County 10.5 miles northeast of Greenville. It currently has one operating unit, Unit 3. Units 1 and 2 were replaced with natural gas generation in Spring 2017. Unit 3 will continue operation with emission controls.

With a long-standing commitment to safe and reliable operations and to environmental stewardship, TVA began to modernize its coal ash management in 2009 including converting from wet to dry ash storage. This effort was later endorsed by the TVA Board in 2011.

The EA informed TVA decision makers, regulators and the public about the environmental consequences of the proposed action which included the following projects:

• construct and operate a new fly ash gypsum dewatering facility
• construct and operate a new dry fly ash conversion system
• construct and operate a new CCR landfill
• close the gypsum pond disposal complex
• close the 2A/2B Boiler Slag Pond and repurpose as Process Water Basins
• close the Peabody Ash Pond

After further consideration, TVA proposed to move the Process Water Basin location just north of the originally proposed location (former 2A/2B Boiler Slag Pond) and prepared a supplemental analysis to evaluate the change. On August 9, 2018, TVA issued a Final Supplemental EA and FONSI on the construction of Process Water Basins in the newly proposed location.
