Original warning text
T/V Exxon Valdez; Bligh Reef, Prince William Sound, Alaska. Bligh Reef, Prince William Sound, Alaska. 1. On March 24, 1989, the tanker Exxon Valdez, en route from Valdez, Alaska to Los Angeles, California, ran aground on Bligh Reef in Prince William Sound, Alaska. The vessel was traveling outside normal shipping lanes in an attempt to avoid ice. Within six hours of the grounding, the Exxon Valdez spilled approximately 10.9 million gallons of its 53 million gallon cargo of Prudhoe Bay Crude. Eight of the eleven tanks on board were damaged. The oil would eventually impact over 1,100 miles of non-continuous coastline in Alaska, making the Exxon Valdez the largest oil spill to date in U.S. waters. The response to the Exxon Valdez involved more personnel and equipment over a longer period of time than did any other spill in U.S. history. Logistical problems in providing fuel, meals, berthing, response equipment, waste management and other resources were one of the largest challenges to response [...] 2. COMMODITY: PRUDHOE BAY CRUDE. MAXIMUM POTENTIAL RELEASE: 10900000 GALLONS. TAGS: COLLISION. 3. POSITION 60.839N 146.883W. NOAA INCIDENTNEWS 6683: https://incidentnews.noaa.gov/incident/6683
