Liquid Hydrocarbon Spills

Emergency Response Team
Emergency Response Team in action in the aftermath of Hurricane Katrina. This experience gave us new insights into how to respond to emergency situations that hugely impact both the community and our facilities simultaneously.
ConocoPhillips reports liquid hydrocarbon spills from primary containment that are greater than one barrel. Spills greater than 100 barrels are considered significant incidents that trigger immediate management reporting, extensive investigation and corrective action to mitigate recurrence.

We had two large spills that greatly increased our spill volume from primary containment. However, the majority of the product was captured in secondary containment and did not reach the environment. In 2006, there were 19 significant liquid hydrocarbon spills resulting in the release of 37,254 barrels from primary containment, compared to 11 such spills in 2005 from which 12,522 barrels were released. (figs. 22 & 23) Two of the 2006 significant spills resulted in 78 percent of the released volume. Both were related to tank leaks that were mostly contained. Eleven of the 2006 significant spills occurred in the refining and marketing sector, which accounts for 95 percent of the volume released from primary containment.

Of the volume released from primary containment, 30,319 barrels, or 81 percent, were captured in secondary containment such as tank dikes and did not reach the environment. Of the 6,935 barrels that did reach the environment, 3,767 barrels, or 54 percent, were recovered during initial spill response. Longer-term remedial projects strive to recover additional lost hydrocarbons.

In 2006, Polar Tankers, Inc. and ConocoPhillips resolved matters relating to a spill of an estimated 1,000 gallons of crude oil into Washington State’s Dalco Passage in Puget Sound. The oil was purportedly from the Polar Texas oil tanker, which has since been decommissioned. Settlements were reached with the Washington State Department of Ecology, U.S. Department of Justice, U.S. Coast Guard and National Pollution Funds Center for reimbursement of cleanup costs and a civil penalty associated with the incident, which occurred in October 2004. While there was no admission of liability, the settlement reflects Polar Tankers, Inc.’s and ConocoPhillips’ commitment to good corporate and environmental stewardship.
