Aniak Tank Farm Release

Date: 3/08/2011

Location: Aniak, Alaska

Incident Summary

AniakOn March 8, 2011, Chadux was notified by Crowley Petroleum Distribution that approximately 23,000 gallons of Jet A had leaked into tank farm secondary containment at their Aniak facility.  All spilled product was contained within the tank farm walls.  This estimated spill amount was revised to less than 7,000 gallons.  An IMT was formed in Anchorage and two Chadux responders flew to Aniak to assess the spill and assist with the recovery of product to an available tank within the tank farm. A personnel order was made for four additional responders the following day. In addition, four contract responders were mobilized to Aniak. Though the tank farm containment was covered by ice and snow, the crew was able to create a sump at the low point and recover the spilled product as it migrated. By March 17, the crew and equipment had been demobed.  Four days later, the member company re-activated Chadux to finish the cleanup process and two responders were mobilized.  The winter phase of the cleanup was terminated on March 30.

 

Aniak Unleaded Gas Release

Date: 4/25/2011

Location: Aniak, Alaska

Incident Summary

On April 25, 2011, approximately 2,000 gallons of unleaded gasoline leaked from a damaged tank into secondary containment in Aniak.  Surrounding homes and businesses were evacuated in response to the potential fire hazard and the local fire department blanketed the standing fuel with foam.  Chadux was mobilized to perform air monitoring, empty fuel remaining in the damaged tank, and recover spilled gasoline.  Initial area monitoring allowed the evacuation zone to be reduced and Chadux response personnel, assisted by Crowley tank farm operators, began pumping the fuel into an undamaged tank.  Work in the tank farm was conducted using ½ face air-purifying respirators and continuous air monitoring was conducted with a 4 gas/ PID meter.  Recovery and transfer of the fuel was largely completed in two days and the Chadux crew began a staged demobilization.

 

Unalaska Pipe Discharge

Date: 2/16/2011

Location: Unalaska, Alaska

Incident Summary

On February 16, 2011, personnel from Chadux member company Delta Western discovered contaminated soil surrounding a gasoline delivery pipeline. The leak was located, secured, and Alaska Chadux was contracted to prevent spilled product from reaching the water.  Following a site assessment it became apparent that the spilled product had not migrated laterally from the release point.  A Chadux responder was retained to assist the remediation contractor and to aid in site air monitoring.

 

Tug Chukchi Sea

Date: 6/5/2011

Location: Dillingham, Alaska

Incident Summary

On June 5, 2011, the Tug Chukchi Sea spilled approximately 27 gallons of diesel fuel while transferring fuel to a day tank.  Some of the fuel ended up in the water near the Delta Western Dillingham dock.  Following several reports of oiled beaches, Delta Western mobilized Alaska Chadux and two responders and a supervisor who flew to Dillingham to assist in-region responders and tug crew to deploy sorbent boom, assess the shoreline impact, and retrieve soiled sorbent boom.

 

Tug Aries Casualty

Date: 6/26/2011

Location: St. George Island, Alaska

Incident Summary

On June 26, 2011, the Tug Aries sank in the Bering Sea approximately 90 miles ENE of St. George Island (56°47’60.00″ N 167°22’60.00″ W).  The vessel came to rest in 260 feet of sea water with an unknown amount of diesel fuel remaining in its tanks.  Once the crew was safely recovered, the Unified Command focused its attention on the incident pollution potential.  Alaska Chadux was retained by the vessel owner to provide guidance during spill response related discussions in the Unified Command.  In this capacity, Chadux personnel identified response resources capable of operating in the Bering Sea, wrote an IAP for on-water observation operations, and developed a practical diesel observation worksheet to be used by on-water observers.  Following several overflights of the site of the sinking where no sheen was noted, the UC ultimately abandoned its pursuit of recovery and response efforts and closed the incident.

 

M/V Nelson Star

Date: 9/28/2011

Location: Unalaska, Alaska

Incident Summary

Nelson StarOn September 28, 2011, the M/V Nelson Star discharged approximately 500 gallons of heavy fuel oil into the harbor while tied to the American Seafoods pier in Unalaska.  Chadux’s Dutch Harbor employee and in-region responders from member companies initiated the initial response to the spill.  Chadux employed two chartered aircraft to move eight response personnel and resources to Dutch Harbor.  Personnel maintained containment around the vessel while cleaning contaminated sections of the hull and the pier sheet piling.  Response activities generated 29 fifty-five gallon drums of recovered oil/water and 23 cubic meters of solid waste; Chadux arranged for the transport and disposal of all waste on the project.  Response operations were concluded on October 9, but maintenance and rehab of gear that was used during the incident is ongoing as of the date of this report.
