Warrenton - The U.S. Coast Guard is investigating an oil sheen that was reported Tuesday night near the Skipanon River in Warrenton.
Coast Guard Marine Safety Office Portland received a report from a Weyerhaeuser employee reporting an oil sheen at 4:45 p.m., about one-quarter mile upriver of the mouth of the Skipanon River.
An HH-60 Jayhawk helicopter from Air Station Astoria was launched at 4:58 p.m. to survey the spill.
Cowlitz Clean Sweep was immediately contracted to clean up the spill. Workers were able to recover more than eight gallons of oily product, the Coast Guard reported. The total spill size was estimated at 25 gallons of oil. Much of the remaining product had dissipated and was unrecoverable. The type and grade of oil is unknown at this time, but there was no shoreline impact and no reports of affected wildlife, the Coast Guard said.
