WARRENTON, Ore. — Coast Guard personnel responded to an approximately 250-gallon diesel spill that left a reported 1-mile by 500-yard sheen in the water at Skipanon Marina on the Columbia River Monday.
Inspectors with the Coast Guard Incident Management Division in Astoria are monitoring the situation while the crew of the fishing vessel Emerald Sea, the responsible party, works with harbormasters to clean the spill using absorbent pads.
Coast Guard responders reported the sheen was dissipating by 1 p.m.
The master of Emerald Sea, an 86-foot fishing vessel homeported in Aberdeen, Washington, reported they spilled the oil while conducting an internal fuel transfer at the marina Monday morning.
Watchstanders at Coast Guard Sector Columbia River received a report of a small sheen that IMD personnel launched to investigate around 9 a.m. They discovered a much larger sheen and were notified of the fuel transfer in the area that morning.
Emerald Sea had since transited to Ilwaco, Washington, where IMD located the crew and requested the master to self-report the spill to Coast Guard National Response Center and return to Skipanon Marina to clean the spill. No sheen was visible in Ilwaco.
No hazards to navigation or affected wildlife have been reported.
