Environmental groups including the Tennessee Clean Water Network, Southern Alliance for Clean Energy and others say an expansion of TVA's Kingston landfill could lead to coal waste leaking into the Clinch River.
TVA has filed for a major permit modification with the Tennessee Department of Environment and conservation for the Kingston site and plans an expansion to store waste generated by the Kingston Fossil Plant.
Opponents say the site is unstable and not suited for a landfill due to sink holes and other karst geologic features.
As part of the permitting process, TVA submitted an updated operations manual for the site, which details preliminary expansion efforts begun in September 2013 and estimates Phase II of construction from 2016 to 2020 depending on TDEC approval.
TDEC will review public comment on the proposal through Tuesday.
