Duke Energy has settled a landmark lawsuit over air pollution at coal-burning power plants in North Carolina.

The suit was first filed in 2000 by the U.S. Justice Department, on behalf of the EPA. They alleged that Duke Energy violated the federal Clean Air Act by unlawfully modifying 13 coal-fired electricity generating units located at the Allen, Buck, Cliffside, Dan River, and Riverbend plants, without obtaining air permits and installing and operating the required air pollution control technologies.
