Whenever there is an incident involving more than one agency with jurisdiction, a joint command arrangement, called the Unified Command is implemented. This webpage provides a compilation of general information, reports, press releases, maps and relevant links meant to aid members of the Unified Command and inform the public during a response. Not all information provided here has been jointly approved or endorsed by every member of the Unified Command.

The spill was from an 18-inch three-phase common line carrying a mixture of crude oil, produced water, and natural gas. Total estimated volume of oily material released is 45,828 gallons (1,091 barrels); this is a preliminary figure only.
A visual inspection of the pipe on Monday, December 7, identified a rupture as the source of the leak. According to cleanup officials, the rupture is approximately 24 inches lengthwise, located on the bottom of the pipe. The rupture is consistent with an overpressure scenario, linked to ice plugs forming inside the pipe. However, separate investigations by BP and the State of Alaska into the cause are ongoing.
