RALEIGH -- Critics fighting Duke Energy's proposed coal-burning power plant in Western North Carolina have renewed legal challenges to block it as a global warming threat.
The groups argue that construction on Duke's Cliffside plant should be stopped because a permit issued by the state Division of Air Quality didn't require emission controls on carbon dioxide, a major greenhouse gas.
An EPA panel recently rejected a federal permit for a Utah coal plant because it didn't consider controlling carbon dioxide emissions. The new challenges by N.C. Waste Awareness and Reduction Network in Durham and the Southern Environmental Law Center in Chapel Hill cite the EPA decision.
More than a half-dozen lawsuits and challenges have been filed against the Cliffside project in federal court.
