The National Defense Reserve Fleet will remain in the James River in southeastern Virginia, after a federal judge blocked the ships from being towed to the U.K. where they are slated to be dismantled. The 1940s-built Canisteo and Caloosahatchoo, were the first of the 13 ships scheduled to leave today for their scrapping destination at Teesside, England where AbleUK would dismantle the ships and dispose of the hazardous materials. The ships, dubbed the Ghost Fleet, contain up to 100 tons of polychlorinated biphenyls (PCBs) as well as significant quantities of asbestos and fuel oil. Environmental groups urged Judge Rosemary M. Collyer to block the scheduled towing of the vessels, stating that the agency responsible for the ships failed to follow environmental regulations.
