New Orleans - People along the Gulf Coast are getting an unpleasant reminder of the 2010 Gulf Oil Spill, thanks to Hurricane Isaac.
Tar balls have washed up on shore on many beaches.
It's believed the deposits of tar are weathered oil from the 2010 Deepwater Horizon oil rig explosion.
BP said Wednesday that the deposits at Port Fourchon are from the spill, and is investigating if the oil on other parts of the coast are from another source.
Louisiana officials say the tar balls and a large oil mat have been spotted along the gulf shore south of New Orleans.
They've also found at least three oiled animals.
When Isaac stormed ashore last week it damaged or destroyed at least 13,000 homes.
