In 2004, upturned anchor embedded in Delaware River riverbed punctures single-hulled oil tanker, spilling 264,000 gallons of crude, a mere 900 feet from its destination after a 1,900-mile journey. (Single-hulled tankers are now banned from WOTUS.) Cleanup is successful, costs $143 million. Who pays? The shipping company and the gov’t can recover much of their cleanup costs from the oil company, says the Third Circuit.
