BP potentially faces billions of dollars in new fines after a New Orleans judge concluded it acted with "gross negligence" ahead of the massive 2010 Gulf of Mexico oil spill. Federal court judge Carl Barbier said that the April 20, 2010 Deepwater Horizon drilling rig blow-out, which killed 11 and spilled millions of barrels of oil into Gulf waters, happened because BP''s US subsidiaries, along with oil-services company Halliburton and rig owner Transocean, did not take adequate care in drilling a risky well.
Barbier said that the British oil giant knew that the Macondo well it was drilling, called by some working on it the "well from hell", was particularly dangerous because of the high danger of a blow-out. BP''s decisions throughout the drilling process qualified as "gross negligence" because they were "an extreme departure from the care required under the circumstances or a failure to exercise even a slight care." He also said BP''s role involved "wilful misconduct", adding to the penalties that, based on a maximum fine of $4,300 per barrel spilled, could result in a fine of up to $18 billion under the Clean Water Act. As the operator of the project, BP is solely liable for the penalties arising from violations of the Clean Water Act.
