This is the second time in recent months that there has been a collision between a tanker and a dredge barge in the waters near Staten Island.
On January 24th, the 669-foot ship carrying orange juice - called the Orange Sun - and two dredging vessels collided in the bay just before 2 p.m., leaking an unknown substance in the frigid waters.
