This has been in the news some, but I hadn't decided to make a thread about it.
Basically on March 31st the Pegasus oil pipeline ruptured near Mayflower Arkansas. It spilled 10,000+ barrels of oil (A barrel = 53 gal. or 158L) Mayflower is a small town about 20 minutes north of Little Rock, where I grew up, and about 15 minutes south of Conway, where I went to college, so I know this area pretty well.
Interestingly, what spilled is not crude oil. Rather it is "diluted bitumen." What they mine out of the tar sands fields in Canada is far closer to solid tar than it is crude oil. They blast the tar sands with steam and chemicals to free the oil, then they mix the oil with light petroleum compounds to make it liquid enough to flow before transporting it.
Exxon evacuated people and shut the pipeline off the day of the spill, and have been cleaning it up. But at the same time, they, along with police have basicaally created an exclusion zone. If you're trying to approach the spill area on main roads police will tell you to turn around. Reporters are being barred from the site of the spill they also Pissed off the Arkansas Attorney General by trying to herd him into a "tour" of the area rather than freely moving about
Thankfully, this is rural Arkansas and there's more than one way to get into anywhere, and people have been taking videos of the oil.
