OIL SHEEN – OIL LEAK – OIL SPILL – MARINE TERMINAL LEAK – VESSEL LEAK On September 19, 2016, the YAMUNA SPIRIT began discharging her Arabian Extra Light crude cargo at the Phillips 66 Marine Terminal, Rodeo Refinery, California. Shortly after operations commenced, a series of odors and oil sheens were observed nearby in San Pablo Bay, San Francisco. The parties, in cooperation with the USCG and state agencies, conducted extensive investigations and testing to determine whether the source of the leak was the Terminal or Vessel. Both parties contended that the other was the source of the oil. Arbitration was sought to establish responsibility for the leak and recover the expenses associated with the oil spill responses, investigations, and legal fees.
