      Unified Command News Release
      San Mateo Mystery Oil Spill

      Date: February 8, 2002 Time: 11:30 a.m.

      Oily seabirds mystery solved

      The U.S. Coast Guard Marine Safety Office - San Francisco and
      California Department of Fish and Game Office of Spill Prevention and
      Response (OSPR) have identified the source of oil that has incapacitated
      or killed over 1,541 seabirds off the northern California coast since
      November 24. It is the SS Jacob Luckenbach, a 468-foot freight ship
      that sank approximately 17 miles Southwest of the Golden Gate Bridge, on
      July 14, 1953 as the result of a collision.

      In a statement released today, Governor Gray Davis said, " I would
      like to thank the Department of Fish and Game's Office of Spill
      Prevention and Response and the U.S. Coast Guard for their tireless
      efforts in spearheading the search for the source of the oil spill that
      has depleted California's offshore bird populations over the last ten
      years. The comprehensive, team approach with the State Lands
      Commission, the National Atmospheric and Oceanographic Administration,
      U.S. Navy Salvage personnel, and the National Marine Sanctuaries, along
      with the response industry, brought together experts in oiled wildlife
      treatment and rehabilitation, satellite imagery, vessel operations,
      ocean currents, resource economics, wildlife behavior, and oil
      fingerprint analysis."

      On Tuesday, a submersible remotely operated vehicle (ROV), owned by
      Vortex Diving Co. of Alameda, was lowered to the Luckenbach. The ROV's
      video camera did not show any direct evidence of oil coming from the
      ship, but the ORV did observe minor amounts of oil moving about in one
      of the vessel's cargo holds, and USCG and OSPR personnel in surface
      vessels observed small amounts of oil on the surface above it. In
      addition, the ROV support vessel Eaglet observed oil stains on its
      anchor chain when the anchor was pulled up. The ROV collected oil
      samples from the surface above the wreck and from the support vessel's
      anchor chain. Coast guard personnel were also able to obtain samples of
      the surfaced oil.

      Those oil samples were immediately sent to both OSPR's Petroleum
      Chemistry Laboratory near Sacramento and the Coast Guard's Marine Safety
      Laboratory in Groton, Connecticut. Both labs independently analyzed the
      oil's chemical make-up, then compared the resulting "fingerprint" with
      those taken from oiled birds' feathers, tar balls, and oil sheen
      observed and sampled on December 8, 2001. They matched.

      "This is very exciting. We've been trying to find the sources of
      mystery spills for years, so this discovery is truly gratifying." said
      Bill Castle, Supervising Chemist at the State lab. "There's a real
      sense of relief, because these spills create a big problem for us and
      for our wildlife."

      The Unified Command (USCG and OSPR) now has the significant challenge
      of identifying the best way to remove the threat of further discharges
      from the oil source into the environment. The U.S. Navy Supervisor of
      Salvage (SupSalv) has been called in to provide technical expertise to
      the unified command in developing plans for any salvage efforts.

      The Jacob Luckenbach is one of several sunken vessels in Gulf of the
      Farallones National Marine Sanctuary that was being investigated as a
      possible source of numerous "mystery" oil spills. Details on the
      vessels and collision are on the Internet, at
      http://www.cinms.nos.noaa.gov/bridge/dbase/gfmns/jacobluckenbach.html.


      "The investigation to identify the source of the mystery spill has
      been a scientific process of elimination," said Scott Schaefer, OSPR
      Deputy Administrator. Shortly after the oiled birds were discovered,
      both OSPR's and the Coast Guard's labs were able to determine that the
      samples were from the same source and that the source was not consistent
      with natural oil seeps from the Monterey Formation or with Alaskan North
      Slope crude oil. Both labs identified the oil as either a heavy fuel
      oil or an unidentified crude oil.

      In early January, six weeks into the current incident, birds coated
      with fresh oil were still being recovered along a 220-mile stretch of
      California's coast. This led investigators to suspect either multiple
      releases from the same vessel or from a submerged vessel. According to
      OSPR Administrator Harlan Henderson, "A diverse group of experts was
      assembled from federal, state and local agencies, as well as
      representatives of the maritime industry. We operated under a Unified
      Command @ consistent with the State Oil Spill Contingency Plan @ which
      brought all the key players together as a team and allowed us to openly
      share all information. This validates the old saying that 'none of us
      are as smart as all of us.' We used all available technologies,
      including satellites, trajectory modeling, seismic data, and petroleum
      fingerprinting."

      Investigators from the Coast Guard, OSPR, and the State Lands
      Commission searched vessel traffic records and identified several oil
      tankers as potential spill suspects because of their routes and cargo.
      Law enforcement personnel obtained oil samples taken from these vessels
      by commercial laboratories. OSPR's Petroleum Chemistry Lab discovered
      that the samples from these oil tankers were not consistent with the oil
      from the feathers on the oiled birds.

      As the investigation proceeded, the theory that a sunken vessel off
      shore was the source became more credible. 23 samples of oiled bird
      feathers and three samples of tarballs collected from November 25, 2001
      through January 4, 2002 matched a slick sampled on December 8, 2001,
      which matched samples taken from tarballs and birds' feathers. In
      addition, the December 8 slick matched historical samples taken from
      similar mystery incidents in 1992-93, 1997-98, 1999, and February 2001.


      Since November 24, 2001, the date of the initial report of sea birds
      being impacted by oil, the U.S. Coast Guard and OSPR have been working
      together in a unified effort to locate the source of the oil. In
      addition, the National Oceanic and Atmospheric Administration (NOAA) and
      California State Lands Commission joined the investigative team to solve
      the mystery.

      The multi-agency investigative team utilized numerous methods and
      technologies to assist them in their search. Sightings from Coast Guard
      aircraft and patrol boats, Department of Fish and Game wildlife
      observation aircraft, and commercial contract helicopters identified oil
      sheens and some tarballs southeast of the Farallon Islands. Commercial
      satellite photos also indicated the presence of oil sheens in the area.
      Even a seismic study was employed. Local outreach that targeted
      commercial and fishing vessels that operate in the area was used. A
      marine radio broadcast was transmitted that asked these operators to
      keep an eye out for oil and to immediately contact the Coast Guard if
      any was observed.

      Investigators searched available databases and identified several
      sunken vessels in the vicinity of the Farallon Islands. These included
      the Chemical Tanker Puerto Rican, which exploded and sank in 1984, the
      aircraft carrier USS Independence, which was intentionally sunk in the
      1950's, two Navy oilers that sank in heavy seas in 1945, and a couple of
      other commercial vessels, including the Jacob Luckenbach.

      "Now that the source of the oil has been identified and the team
      prepares for the oil recovery operation," Governor Davis said, "I
      reaffirm my continuing support, and look forward to the day when this
      threat is finally eliminated."

      As of February 7, 2002, 1,541 oiled birds have been brought to the
      Wildlife Care Center in Cordelia. Six-hundred and twenty-seven were
      captured alive, and 914 were dead on arrival. Of the 627 live birds,
      206 have been cleaned, rehabilitated and released; 8 are still receiving
      care, and 413 have died in captivity.

      The Wildlife Care Center no longer needs new volunteers, at this time.
      However, people interested in volunteering too help in future oil spill
      incidents may register on the OSPR web-site -
      http://www.dfg.ca.gov/Ospr/volunteer/volunteer.html, or visit the
      IBRRC website, http://www.ibrrc.org

      "Thanks to all the volunteers who worked on this incident," said Oiled
      Wildlife Care Network Veterinarian Scott Newman. "Only with the help of
      the volunteers were we able to get through this. We appreciate the time
      and energy they've given."
