Not a joke: on Friday, an Exxon pipeline carrying crude oil from the tar sands region of Alberta leaked about 10,000 barrels of corroding, low-quality crude oil into an Arkansas town — Exxon cleanup crews are trying to keep the oil from reaching Lake Conway, a popular game-fishing spot, through storm drains. [Washington Post]
Jeffers said that the company received phone calls from people in the area at the same time its pipeline monitors in Houston noticed a drop in pressure in the line…. Exxon Mobil said that fumes from the oil spill posed a risk in “high pooling areas,” where oil could be seen on the ground and where crews were working with safety equipment. …
The Arkansas incident also comes just a few days after a Canadian Pacific Railroad train carrying oil sands crude — a mixture of heavy bitumen and lighter dilutents — from Alberta to Chicago derailed near Parkers Prairie, Minn., spilling about 357 barrels.
That accident drew attention because the State Department’s new environmental impact statement on the Keystone XL said that if the pipeline were blocked, oil sands crude would still be able to reach markets via railroads, which carry more than 1 million barrels a day of oil in the United States. Supporters of the pipeline say that shipping oil by pipeline would be safer and more fuel efficient than doing so by rail.
