Tanker Captain Pleads |Guilty to Enviro Felony

(CN) - The Filipino captain of the tanker ship T/V Green Sky, pleaded guilty Monday to one felony count of obstructing a U.S. Coast Guard investigation into pollution crimes aboard the vessel.

The charge stemmed from a Coast Guard investigation in late August 2015 into the bypass of pollution prevention equipment, including the use of a "magic device," on the Green Sky.

According to court documents, members of the ship's engine room, including a senior officer, admitted to illegally discharging overboard. These admissions occurred prior to the August 2015 Coast Guard inspection at the Port of North Charleston.

During the inspection, Capt. Genaro Anciano made several false and misleading statements to the Coast Guard to cover up the illegal conduct, the government said.

The T/V Green Sky is a 30,263 gross ton, ocean-going vessel that operates as a petroleum and chemical tanker. The vessel, which is owned by an entity incorporated in the Marshall Islands, is approximately 600 feet in length and is registered in Liberia.

Over the course of several days, the normal operation of the Green Sky generates thousands of gallons of bilge wastes that are contaminated with petroleum products and oil residues. These bilge wastes must be removed for the vessel to operate safely.

Both the United States and Liberia are parties to the MARPOL treaty, which regulates the overboard discharge of bilge waste. It was prohibited to discharge bilge wastes from the T/V Green Sky without first running that effluent through the ship's oily water separator.

According to the MARPOL treaty, all overboard discharges from the vessel's bilges had to be recorded in the T/V Green Sky's oil record book. A bypass of the oily water separator, which is not recorded in the oil record book, jeopardizes the accuracy and integrity of that document. It is a separate federal crime for oceangoing vessels to enter a U.S. port with a false oil record nook.

No date has been set for Anciano's sentencing.
