"NASHVILLE, Tennessee — Two Tennessee environmental groups claim toxic pollution from a coal-burning power plant is seeping into the Cumberland River and state regulators are not doing enough to stop it.

The allegations are part of a lawsuit filed Tuesday in federal court in Nashville against the Tennessee Valley Authority.

The Tennessee Clean Water Network and Tennessee Scenic Rivers Association first threatened to sue in November, claiming state regulators have known about problems at the 1950s-era Gallatin Fossil Plant for years."
