NEW ORLEANS—The Coast Guard says an oil sheen near the site of the massive BP spill in the Gulf of Mexico matches oil from the 2010 disaster.
The Coast Guard says its tests established the oil came from the BP well.
It could be left over from the wreckage of the Deepwater Horizon rig or debris from the calamity.
In a news release, the Coast Guard said BP PLC and the sunken rig’s owner, Transocean, were informed they may be held financially liable for the new oil.
Capt. Duke Walker said the sheen was first reported Sept. 16 by BP based on satellite images.
Walker says the sheen does not pose a risk to the shoreline and cannot be cleaned up.
