HOUSTON -- The fate of a much-criticized plea deal that fines BP PLC $50 million and sentences the oil giant to three years’ probation is now in the hands of a federal judge.

U.S. District Judge Lee Rosenthal on Tuesday listened to a final set of arguments about why she should either accept or reject the plea agreement. Rosenthal gave no indication about when she would rule.

During a hearing Tuesday, attorneys for victims of the 2005 explosion at the company’s Texas City plant reiterated their contention that the fine is too low and that BP would not meet its safety obligations at the facility.

But federal prosecutors and BP say the fine was the highest possible and that government agencies are making sure the oil giant is running a safe plant.
