The Arkansas tar sand oil spill puts us in a Keystone XL/Ogallala Aquifer frame of mind - - but let's not forget that in July, 2010, Enbridge spilled a huge amount of tar sand oil into the Kalamazoo River right next door in Michigan.
And that one is still being cleaned up:
The U.S. Environmental Protection Agency is ordering Enbridge Inc. to do additional dredging in the Kalamazoo River to clean up oil from a massive 2010 spill....Enbridge? Here's its record...
The order comes more than two years after a 30-inch pipeline owned by Enbridge ruptured near Marshall and then traveled about 35 miles downstream before being contained.
The EPA has said previously that work crews removed 1.1 million gallons of oil and 200,000 cubic yards of oil-contaminated sediment and debris from the river following the July 26, 2010, spill.
