A federal judge has ruled that BP's reckless conduct resulted in the nation's worst offshore oil spill, leaving the company open to billions of dollars in penalties.
U.S. District Judge Carl Barbier's ruling Thursday could nearly quadruple the amount of civil penalties for polluting the Gulf of Mexico with oil from BP's Macondo well in 2010.
BP vowed to appeal the ruling, saying in a news release that the company strongly disagreed with the decision.
Barbier presided over a trial in 2013 to apportion blame for the spill that spewed oil from April 20 to mid-July 2010.
Barbier says BP bears 67 percent of the blame for the spill. He says drilling rig owner Transocean Ltd. takes 30 percent of the blame, and cement contractor Halliburton Energy Service takes 3 percent.
