RALEIGH, N.C. — North Carolina's environmental agency sought late Monday to delay its own settlement with Duke Energy a week after a busted pipe at one of the company's coal ash dumps spewed enough toxic sludge into the Dan River to fill 73 Olympic-sized pools.

Lawyers for the state Department of Environment and Natural Resources asked a judge to disregard their proposed settlement with the nation's largest electricity provider. Under the deal, Duke would have paid fines of $99,111 over groundwater pollution leaking from two coal dumps like the one that ruptured Feb. 2.

The state's letter came one day after a newspaper story in which environmentalists criticized the arrangement as a sweetheart deal aimed at shielding Duke from far more expensive penalties the $50 billion company might face under the federal Clean Water Act. The settlement would have required Duke to study how to stop the contamination, but included no requirement for the company to actually clean up its dumps near Asheville and Charlotte.

CARSON CITY, Nev. — Nevada's attorney general and governor said Monday they won't defend the state's gay marriage ban pending before a federal appeals court, saying a recent court decision made the state's arguments “no longer defensible.”Attorney General Catherine Cortez Masto filed a motion with the 9th Circuit Court of Appeals that said Nevada's legal arguments supporting the voter-approved prohibition aren't viable in light of the court's recent ruling that said potential jurors cannot be removed from a trial during jury selection solely because of sexual orientation.
