The 20 meter long towboat Sonny J partially sank on the Mississippi River near Vidalia, Louisiana. The towboat sank with some 4,000 gallons of diesel fuel on board, but the fuel tank vents remained above water. Reports state the vents have been sealed and a containment boom has been deployed around the vessel. A light sheen could be seen around the Sonny J and absorbent pads were used to collect the pollution. No reports of injuries. The cause of the sinking is under investigation.
