BP has already pleaded guilty to criminal charges including manslaughter
US authorities plan to propose a $16bn settlement to British energy giant BP for civil claims related to the disastrous 2010 oil spill in the Gulf of Mexico, the Wall Street Journal
Citing people familiar with the discussions, the newspaper said late on Friday that the settlement would cover fines BP owes under the Clean Water Act, a federal water pollution law, as well as payments under the Natural Resources Damage Assessment, an environmental evaluation.
But the Journal noted that it remained unclear whether the government had formally proposed the offer to BP.
The April 20 2010 explosion on the Deepwater Horizon oil rig, operated by BP off New Orleans, killed 11 people and spilled hundreds of millions of gallons of crude oil into the Gulf of Mexico in the four months it took to cap the well.
BP vowed Tuesday to "vigorously defend" itself in court against what it termed "excessive" fines for the incident.
The company already pleaded guilty, in November, to criminal charges -- including felony manslaughter -- and agreed to pay a record $4.5bn in criminal fines.
It reached a $7.8bn settlement early last year to cover the bulk of the outstanding private claims for economic loss, property damage and medical problems.
BP has paid out $10bn to businesses, individuals and local governments impacted by the spill and spent more than $14bn on the response and cleanup.
The oil firm also remains on the hook for billions in additional damages, including the cost of environmental rehabilitation.
