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
Deepwater Horizon oil spill and payments to a trust fund had cost the company $42.2 billion. In September 2014, a U.S. District Court judge ruled that BP was primarily responsible for the oil spill because of its gross negligence and reckless conduct. In July 2015, BP agreed to pay $18.7 billion in fines, the largest corporate settlement in U.S. history. How the misuse of categorical exclusion for National Environmental Policy Act (NEPA) compliance relates to this spill is described in Regulatory Capture. The "Deepwater Horizon" was a 10-year-old semi-submersible, mobile, floating, dynamically positioned drilling rig that could operate in waters up to deep. Built
