ANCHORAGE, Alaska – During a scheduled testing of the fire command system at Pump Station 9 today, the station experienced a power failure at approximately 10:20 a.m., resulting in the tank relief valves opening as they are designed to do. Subsequently, Tank 190 overflowed and crude oil was released to secondary containment. This occurred as Alyeska was conducting fire command and valve leak testing at the pump station, located near Delta Junction, during a planned pipeline shutdown.

There were no injuries and personnel have been evacuated. The pipeline is currently shut down and the North Slope Producers have been prorated to 16 percent. An Incident Management Team has been activated to manage the situation. Alyeska estimates that the potential spill volume to containment is up to several thousand barrels. The containment area has a capacity of 104,500 barrels. Additional spill response crews and equipment are en route. More information will be provided when available.
