- 2010
- Jan. 23, Port Arthur, Texas: The oil tanker Eagle Otome and a barge collide in the Sabine-Neches Waterway, causing the release of about 462,000 gallons of crude oil. Environmental damage was minimal as about 46,000 gallons were recovered and 175,000 gallons were dispersed or evaporated, according to the U.S. Coast Guard.
- April 24, Gulf of Mexico: The Deepwater Horizon, a semi-submersible drilling rig, sank on April 22, after an April 20th explosion on the vessel. Eleven people died in the blast. When the rig sank, the riser--the 5,000-foot-long pipe that connects the wellhead to the rig--became detached and began leaking oil. In addition, U.S. Coast Guard investigators discovered a leak in the wellhead itself. As much as 25,000 barrels (1,050,000 gallons) of oil per day were leaking into the water, threatening wildlife along the Louisiana Coast. Homeland Security Secretary Janet Napolitano declared it a "spill of national significance." BP (British Petroleum), which leased the Deepwater Horizon, is responsible for the cleanup, but the U.S. Navy supplied the company with resources to help contain the slick. Oil reached the Louisiana shore on April 30, affected about 125 miles of coast. By early June, oil had also reached Florida, Alabama, and Mississippi. It is the largest oil spill in U.S. history.
