So far, the thousands of barrels of tar-sands oil that spilled into a middle-class neighborhood in central Arkansas on Friday have driven 22 families from their homes and killed and injured a grip of local wildlife. So far, the oil hasn't contaminated the local lake or drinking water supply, according to ExxonMobil. It's a "major spill," according to the EPA, and the cause is so far still under investigation.
But since it's not oil-oil, ExxonMobil hasn't paid into the government clean-up fund that would help bankroll the epic scrub-down necessary to rid poor unsuspecting Mayflower, Ark., of all that bitumen.
"A 1980 law ensures that diluted bitumen is not classified as oil, and companies transporting it in pipelines do not have to pay into the federal Oil Spill Liability Trust Fund," writes Ryan Koronowski at Climate Progress. "Other conventional crude producers pay 8 cents a barrel to ensure the fund has resources to help clean up some of the 54,000 barrels of pipeline oil that spilled 364 times last year."
