gallatin coal fired power plant

NASHVILLE, Tenn. (AP/WMOT) — The Sierra Club has filed a lawsuit against the Tennessee Valley Authority over a Freedom of Information Act request for documents.

The environmental organization is trying to learn more about the utility's plan to spend nearly $1 billion to reduce emissions at its coal-fired power plant in Gallatin.

Louise Gorenflo with the Tennessee chapter of the Sierra Club notes that the Gallatin plant is nearly 60 years old. She says the group believes the cost of updating its environmental controls will exceed the value of the plant.
