The former Amoco oil refinery at Texas City, Texas, was beset by environmental issues, including chemical leaks and a 2005 explosion that killed 15 people and injured hundreds. Bloomberg News described the incident, which led to a guilty plea by BP to a felony Clean Air Act charge, as "one of the deadliest U.S. industrial accidents in 20 years." The refinery was sold to Marathon Petroleum in October 2012.[94]
