Case Description


On July 22, 1991, the Japanese fishing vessel Tenyo Maru and Chinese freighter Tuo Hai collided within Canadian Territorial waters approximately 20 miles northwest of Cape Flattery. The Tenyo Maru , which was reportedly carrying 354,800 gallons of intermediate fuel oil, 97,800 gallons of diesel fuel, and 22,500 gallons of fish oil, sank at collision. It initially leaked a large amount of oil and undetermined amounts were reported leaking for more than a month after the collision. Beaches were fouled with oil from Vancouver Island, British Columbia to northern Oregon. While impacts were scattered along the entire Washington State shoreline and the northern beaches of Oregon, the heaviest oiling occurred along the Makah Indian Reservation and the Olympic National Park shoreline.
