The Environmental Protection Agency (EPA) has concluded its assessment of the recent incident that caused a barge containing approximately 850 cubic yards of material dredged from the Gowanus Canal Superfund Site in Brooklyn, NY to become submerged, under high tide conditions, in the Upper New York Bay near Red Hook and Gowanus Bay.

Based on calculations on the barge contents once it was refloated and berthed back at the canal, EPA has concluded that material released from the barge, if any, was minimal.
