Results from the Council’s efforts to monitor the long-term environmental impacts of the operation of Alyeska Pipeline Service Company’s Valdez Marine Terminal and associated tankers since the Exxon Valdez oil spill have shown oil contamination in Prince William Sound and the Gulf of Alaska has reached all-time low values. The Council has been conducting environmental monitoring since 1993.
Alyeska and its owner companies have implemented several improvements over the years which have contributed to the reduction of pollutants being discharged. These include the elimination of single-hulled tankers and Alyeska’s ability to effectively operate their Ballast Water Treatment Facility which removes oil contamination from tanker ballast water.
