Original warning text

T/V Overseas Boston; March Point, Anacortes, Washington.
March Point, Anacortes, Washington.
1. At 0630 on March 18, 1988, the 633-foot crude oil tanker Overseas Boston, was taking on ballast water after discharging its cargo of North Slope crude at the Shell Refinery at March Point near Anacortes, Washington. When a ballast line failed, approximately 5,000 gallons of residual oil discharged into the water. Initial observations of the spill showed oil only around the terminal facility. Several hours later, reports of oil away from the facility instigated an overflight which found oil spread over a several mile area. USCG district 13.
2. COMMODITY: NORTH SLOPE CRUDE. MAXIMUM POTENTIAL RELEASE: 5000 GALLONS.
3. POSITION 48.504N 122.568W. NOAA INCIDENTNEWS 6564: https://incidentnews.noaa.gov/incident/6564
