RESTORE Act Gulf Coast. On April 20, 2010, the Deepwater Horizon, an oil rig located in the Gulf of Mexico that was owned by Transocean and drilling for British Petroleum (BP) exploded, killing 11 workers and injuring 16. The rig burned for over a day before it sunk into the gulf on April 22, 2010. Following the explosion, the seafloor oil gusher flowed for 87 days, spilling an estimated 4.9 million barrels of oil into the gulf. The spill resulted in widespread damage to the environment and ecology of the gulf coast states, as well as subsequent economic damage to their tourism
Oil spill volume is a limited measure of damage or impact. Smaller spills have already proven to have a great impact on ecosystems, such as the "Exxon Valdez" oil spill because of the remoteness of the site or the difficulty of an emergency environmental response. Since 2004, between 300 and 700 barrels of oil per day have been leaking from the site of an oil-production platform 12 miles off the Louisiana coast which sank in the aftermath of Hurricane Ivan. The oil spill, which officials estimate could continue throughout the 21st century, will eventually overtake the 2010 BP Deepwater Horizion disaster as
