TVA's board of directors on Thursday approved what they called a historic agreement to settle a 12-year-old string of clean-air lawsuits involving the EPA, four states and three environmental groups.

In the settlement, TVA agreed to idle retire 18 older coal-fired power-generation units at three plants, shutting down the Johnsonville plant entirely and turning the John Sevier plant into a gas-powered electric generating plant.
