Unified Response Team Concludes Avon Wharf Incident Response

MARTINEZ, Calif.  – Representatives of the Avon Tug Boat Incident emergency response team -representing the United States Coast Guard, California Dept. of Fish & Game-Office of Spill Prevention and Response, Tesoro Refining & Marketing Company, and Marine Spill Response Corporation- at 10:45 A.M. PDT, concluded active response activities associated with a tug boat collision earlier this morning at the Tesoro Golden Eagle Refinery’s Avon wharf.

Earlier concerns that as much as 1,500 gallons of gasoline had been released into the waters of Suisun Bay from a damaged pipeline at the wharf proved unfounded. The integrity of the wharf’s main product transfer line was never breached; a small, ½-inch diameter sample line was damaged, but only released approximately five gallons of gasoline.

Eleven containment and collection vessels operated by Tesoro, the Coast Guard and local spill response organizations had been deployed following the incident, which occurred at 12:20 A.M. when a sea going tug boat, the Independence, operated by AmNav Maritime Services, a unit of Sortwell, Inc., collided with the wharf. Three boats will be maintained on site for the foreseeable future as a precaution, while damage assessment and repairs are begun at the wharf. As an added precaution, 800-feet of containment boom has been deployed around the damaged section of the wharf.

Investigations into the cause of the incident continue under the auspices of regulatory agencies, including the Coast Guard, Dept. of Fish & Game, Contra Costa County, and regional air and water quality agencies.
