The operator of a ship that discharged 34 metric tons of oily bilge water and waste sludge has been fined $500,000, federal prosecutors say.
Authorities said Thursday that the ship, M/V Bulk Victory, is banned from calling on ports of the United States for three years.
The U.S. Attorney's Office said in a news release that Pacific and Atlantic, which has its main offices in Greece, operated the Bulk Victory, a 13,697 gross ton cargo ship.
Authorities say in March, the U.S. Coast Guard boarded the vessel in the Delaware Bay Big Stone Anchorage to conduct an inspection.
Prosecutors say an investigation determined that from January through September 2013, the ship had discharged the bilge water and sludge.
