Two years after the worst offshore oil spill in U.S. history, mats of oily tar from BP Plc.’s ill-fated Macondo well have turned up on Louisiana’s shore after Hurricane Isaac stirred up submerged oil deposits, BP officials said on Tuesday.

BP said the oil that washed ashore after Hurricane Isaac made landfall in Louisiana on Aug. 28 was not unexpected, after Tropical Storm Bonnie in July 2010 buried oil under tons of sand. Isaac’s winds and tidal surge peeled back layers of sand and exposed tar balls and tar mats that were buried under up to five feet of sand, BP said.
