State environmental officials renewed coal ash landfill permits at Duke Energy’s Roxboro and Marshall steam stations Tuesday.
One permit will enable Duke Energy to expand the current capacity at the Roxboro Steam Electric Plant’s lined landfill by changing the landfill’s side slopes. The permit will provide storage for about 2 million additional cubic yards of material. The five-year operating permit will not expand the footprint of the 91-acre landfill in Person County.
