when did the exxon valdez oil spill occur
Exxon Valdez oil spill The Exxon Valdez oil spill occurred in Prince William Sound, Alaska, March 24, 1989, when Exxon Valdez, an oil tanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef at 12:04 am[1][2] local time and spilled 10.8 million US gallons (260,000 bbl; 41,000 m3) of crude oil over the next few days.[3] It is considered to be one of the most devastating human-caused environmental disasters.[4] The Valdez spill is the second largest in US waters, after the 2010 Deepwater Horizon oil spill, in terms of volume released.[5] Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and severely taxed existing response plans. The region is a habitat for salmon, sea otters, seals and seabirds. The oil, originally extracted at the Prudhoe Bay oil field, eventually covered 1,300 miles (2,100 km) of coastline,[3] and 11,000 square miles (28,000 km2) of ocean.[6][7]
Efforts to stem the Deepwater Horizon oil spill On September 10, Allen said the bottom kill could start sooner than expected because a "locking sleeve" could be used on top of the well to prevent excessive pressure from causing problems. BP said the relief well was about 50 feet (15Â m) from the intersection, and finishing the boring would take four more days.[51] On September 16, the relief well reached its destination and pumping of cement to seal the well began.[52] Officials said on September 18 that the cement pumped in from the base of the well had completed the sealing of the well.[53] On September 19, after pressure testing, Allen declared the well "officially dead".[54]
