Four environmental groups are threatening to sue subsidiaries of Mirant Corp. over coal ash. Defenders of Wildlife, Sierra Club, Chesapeake Climate Action Network, and Patuxent Riverkeeper informed Mirant that they intend to sue over what they say are violations of the Clean Water Act.
They say the energy company has been illegally discharging pollutants into a creek near Mirant's Brandywine landfill. The groups also say Mirant has failed to submit a required report about how it will eliminate toxic discharges at Brandywine.
In a statement, Mirant Mid-Atlantic spokeswoman Misty Allen says the company received the notice but does not comment on pending legal matters.
