NEW ORLEANS (AP) — BP wants to lower the fine per barrel of oil spilled during the 2010 Deep Horizon oil spill in the Gulf of Mexico.

U.S. District Judge Carl Barbier felt differently.

TheĀ federal judge rejected an attempt by BP to lower the fines.

On Thursday, Barbier agreed with government lawyers that BP should face paying up to $4,300 for each barrel of oil spilled.

BP wanted Barbier to cap the amount at $3,000 per barrel, the same amount set by the Clean Water Act in 1990 for gross negligence fines. But federal prosecutors argued that those amounts need to be adjusted for inflation and Barbier agreed.

The ruling leaves BP facing up to $13.7 billion in civil fines for the spill.

Barbier still has not ruled on how much BP should pay. He is expected to make that decision in the coming months.
