What do you get when the company behind the second-worst offshore
oil spill in American history ships oil from the company behind the worst onshore spill in history? You get an oil spill. RELATED: A Solar Showdown in the Southwest; Big Oil's Republican Buy
This was the scene in Mayflower, Arkansas, yesterday. A
ExxonMobil pipeline, dating to the 1940s, apparently ruptured between two houses in a cul-de-sac in the corner of a housing development.

It's a scene straight out of the beginning of a post-apocalyptic movie — thick, black oil running down a suburban street. From an environmental standpoint, the spill was even more dangerous than it looks. That oil, according to
a map provided by the city, flowed down the street, past a highway, and encroached on the shore of Lake Conway. RELATED: Exxon Earns $11 Billion in First Quarter RELATED: Apple Momentarily Passes Exxon as Most Valuable Company
Exxon moved quickly to put up oil containment booms, and there are no reports that any oil has entered the lake. Or, rather, not oil. What spilled is a product called "diluted bitumen," or "dilbit" — the watered-down product of a fuel extracted from oil sands in Alberta, Canada.
It's a product extracted by Canada's Enbridge Inc. Since 2007, the two companies have partnered to bring Enbridge dilbit through the Pegasus pipeline in Arkansas for ExxonMobil to process in its Gulf Coast facilities. It's Exxon's pipeline, running from Illinois to Texas, shipping Enbridge's fuel.
Which should have been an indicator something might go wrong. In 2010, an
Enbridge pipeline near the Kalamazoo River in Michigan ruptured, spilling at least a million gallons of dilbit into the river and other nearby waterways — the largest on-land spill in American history. The company was eventually found to be at fault for the accident, in large part for failing to act to contain the spill for over 17 hours. That same year, ExxonMobil was bumped out of the number-one spot on the list of the worst offshore spills, thanks to BP.
Nor was that even Enbridge's most recent spill. Last July, a pipeline operated by the company
leaked 67,000 gallons of dilbit in a rural area of Wisconsin.
It's been impossible not to
draw comparisons between this weekend's spill and the proposed Keystone XL pipeline. That pipeline, for which the State Department recently signed off on a revised environmental plan, would vastly increase TransCanada's current dilbit transport capacity between Alberta and Oklahoma. The primary point of environmental concern cited in the TransCanada report was the possibility of a major spill. In that regard, TransCanada comes out looking pretty good. Enbridge, however, has seen its product leak three times in three years.
President Obama still has veto authority over Keystone XL — a decision he is
still mulling. Meanwhile, Enbridge's pipelines continue to operate, criss-crossing the United States. Even if that's not preventable, maybe we can make a rule: Pipelines used for partnerships between the company responsible for the worst on-shore spill in American history and the worst off-shore spill prior to 2010 have to use pipelines that are younger than World War II.
