Deal Struck to Cut Pollution at Conowingo Dam

Maryland Gov. Wes Moore on Thursday announced a $340 million agreement with Constellation Energy to reduce pollution flowing from the Conowingo Dam into the Susquehanna River, while also allowing for a new 50-year license to operate the state’s largest source of renewable energy.

Under the deal, Constellation will fund trash and debris removal, improved fish and eel passages, invasive species management, and a new freshwater mussel hatchery. The company will also contribute $18.7 million toward studying whether dredging trapped sediment is scientifically and economically viable.

“This agreement will lead to real improvements in water quality in the biggest tributary of the Chesapeake Bay, while securing the future of one of our state’s largest clean energy producers,” Moore said. “It’s good for the environment, good for energy production, and good for Marylanders.”
