The Exxon Valdez oil tanker ran aground in Prince William Sound spilling hundreds of thousands of barrels of crude oil in Alaska. On March 24, 1989, while owned by the former Exxon Shipping Company, and captained by Joseph Hazelwood bound for Long Beach, California, the vessel ran aground on the Bligh Reef resulting in the second largest oil spill in United States history. The size of the spill is estimated at 40,900 to 120,000 m3 (10,800,000 to 32,000,000 USgal), or 257,000 to 750,000 barrels. In 1989, Exxon Valdez oil spill was listed as the 54th largest spill in history.
