Officials at Coast Guard Sector New York say Monday crews are continuing to monitor the spill at the International-Matex Tank Terminal in Bayonne following Saturday night's accident.
The terminal is about 10 miles south of Manhattan, near where the Kill van Kull meets Upper New York Harbor.
They say pollution responders secured the source of the spill after deploying more than 2,500 feet of containment boom. They say no wildlife appears to have been affected.
They're urging boaters to stay away from the area while more oil is being recovered.
