Site description

The 10-unit Johnsonville Fossil Plant, on the Tennessee River in New Johnsonville Tennessee, is the Tennessee Valley Authority's (TVA) oldest coal plant. Construction began in 1949 and the first unit went online in 1951. The plant will permanently close between 2015 and 2017.

There are four ash disposal areas at the Johnsonville Fossil Plant, including an 87-acre unlined island in the Tennessee River, a closed dredged ash disposal area, a closed disposal area in the South Railroad Loop, and an abandoned, unlined coal ash pond north of the plant.

This site is among the U.S. Environmental Protection Agency's list of potential damage cases.
