The Associated Press reports that life-threatening safety violations continue to plague a Texas City BP refinery, leaving it susceptible to another major accident like the one in 2005 that killed 15 people, according to a report released Monday. The report was prepared on behalf of blast victims who object to a federal criminal plea deal with London-based BP PLC related to the accident. The report criticized BP for not conducting a detailed audit of the refinery, not making widespread improvements at the facility and for the plant''s "abysmal safety record" since the blast, which includes three more worker deaths and several fires and chemical releases. BP has said it has vastly improved safety at the refinery, spending about $1 billion on upgrades and repairs. The company pleaded guilty in February and agreed to pay $50 million fine and serve three years'' probation for a BP subsidiary.
