The Tennessee Valley Authority has filed for a permit to build a 54-acre landfill near Gallatin to store coal ash.
TVA spokesman Scott Brooks told WSMV-TV in Nashville that the landfill would hold leftover ash and gypsum that needs to be stored in a dry facility.
Sierra Club spokesman Chris Lunghino says it is critical that the Tennessee Department of Environment and Conservation ensure the landfill is well-engineered and well-sited because coal ash can be toxic.
TVA is still paying to cleanup a massive coal ash spill in 2008 in Kingston in eastern Tennessee.
TVA says the landfill should be ready to operate as soon as construction on the air controls is completed next year.
