Internal emails between staff at North Carolina’s environmental agency show state regulators were coordinating with Duke Energy before intervening in efforts by citizens groups trying to sue the company over pollution leeching from its coal ash dumps. In February, DENR Secretary John Skvarla refuted reports the department intervened. The emails show a Duke lobbyist contacted the N.C. Department of Environment and Natural Resources, where staff exchanged messages discussing “how Duke wants to be sued.” The emails were provided Thursday to The Associated Press by the Southern Environmental Law Center, which had filed notice in January 2013 of its intent to sue Duke under the Clean Water Act. The agency used its authority to intervene in the lawsuit, quickly negotiating a proposed settlement where the billion company would pay a ,100 fine but be under no requirement to stop its pollution. This information comes on the same day Democrats at the North Carolina legislature say Duke Energy should be forced to move all of its coal ash to lined landfills away from water and make shareholders – not customers – pay for the cleanup. House and Senate Democrats unveiled Thursday the framework of a bill they intend to introduce when the General Assembly reconvenes in May. They want Republicans in charge of the legislature to join them given last month’s coal ash pond rupture along the Dan River. Durham Democratic Representative Paul Luebke says the spill is Duke’s responsibility.
