On January 27, 2001, a fuel tanker carrying 8,300 gallons of No. 6 fuel oil (bunker C) overturned on U.S. Highway 20, near Toledo, Oregon. The fuel tanker, owned by Blue Line Transportation of Portland, Oregon, released approximately 5,800 gallons of oil to the roadway. The heated oil flowed across the highway, down a steep bank and into the Yaquina River. The area of visible oil (oil sheen and tarballs) extended from the spill site at river mile 30.2 to just beyond Butler Bridge (Toledo) at river mile 13.2, a distance of approximately 17 miles. The primary collection point for spilled oil was located 0.85 miles downstream of the crash site at Thornton Creek, where approximately 3,300 gallons of oil were recovered. However, a significant amount of product made it past this collection point, with the heaviest accumulations of surface oil observed the first 8 miles downriver from the spill site. During response efforts, NRDA teams observed a number of oiled birds and mammals. One oiled belted kingfisher was captured, cleaned and later released. One heavily-oiled hooded merganser was observed swimming downstream at the oil containment and removal site. A number of additional waterfowl and beaver were observed oiled but not captured. Small, sheening particles of oil were observed emanating from one salmon redd. Additional surveys in February 2001 noted live and dead oiled waterfowl and live oiled beavers, as well as oiling of a beaver trail and numerous otter slides.
