On August 4, the U.S. District Court for the Middle District of Tennessee issued a very significant ruling in the case of Tennessee Clean Water Network, et al., v. Tennessee Valley Authority. The District Court has ordered the Tennessee Valley Authority (TVA) to excavate huge quantities of coal ash waste generated over many years by the TVA’s coal-fired power plant located in Gallatin, Tennessee, and adjacent to the Cumberland River.
Two large unlined surface impoundments have been used to store this waste: the Non-Registered Site and the Ash Pond Complex. According to the District Court, these waste pits are located in an area with “karst geological features, with sinking streams, shallow bedrock, and sinkholes.” These site characteristics caused the District Court to note that “it is difficult to imagine why anyone would choose to build an unlined ash pond in karst terrain immediately adjacent to a river.”
