Description

On December 21, 1985, at approximately 4:25 p.m. PST, the Arco Anchorage ran aground in Port Angeles Harbor. Two holes were torn in the ship's bottom, resulting in a spill of 5,690 barrels (239,000 gallons) of Alaska North Slope crude oil.

This paper describes the Arco Marine response procedure during this spill, and the philosophies and methods used during the spill cleanup. The primary offshore cleanup method was recovery using booms and skimmers. Weather conditions permitted their effective operation. Removal of oiled debris was the primary onshore cleanup method. Port Angeles Harbor is a major timber storage area; log bundles are stored in the harbor awaiting pickup by ships. When log bundles were oiledduring the spill, a method was devised to clean them. Oil percolated into coarse sediments on Ediz Hook, the most heavily oiled area. it was determined that large enough quantities of oil were trapped in the sediments to warrant removal. A cleanup method incorporating a combination of physical agitation to a depth of approximately 12 inches and high-pressure water jets effectively removed most of the entrained oil. The paper also describes the waste management plan that was developed.
