http://bit.ly/1zfNXza Canadian energy delivery company Enbridge Inc. has temporarily shut down and isolated one of its crude oil pipelines that connects to the United States after a 1,350-barrel, or 56,700-gallon oil spill, the company reported Wednesday evening. While the company said it’s not sure how long the cleanup will take or when the pipeline will be re-opened, it insisted that no oil was spilled out of the area within the Regina Terminal in Saskatchewan, where the incident occurred. It’s not yet clear what kind of oil was released — the 796,000 barrel-a-day Line 4 pipeline, which connects to a terminal in Wisconsin, carries heavy, medium, and light sour crude. http://bit.ly/1GXq957
