Blast from the past

A student from last semester's class sent along this item, which is relevant to the Keystone XL pipeline discussion we had at the start of class. It turns out that a pipeline owned by TransCanada, the company that wants to build the pipeline, suffered a massive loss of integrity in 2011 that basically left the area looking like a bomb site. They haven't done a good job of keeping up with inspections, and this part of the forest (though fortunately no people) suffered significant damage because of it. I'd hope that environmental regulations for the XL are more stringent, especially since it seems like they can't be trusted to do a good job of policing themselves.
