SNIPS:

"An Exxon Mobil pipeline that ruptured, leaking oil into Yellowstone River, may have sometimes carried a heavier and more toxic form of crude than initially thought, federal regulators said on Thursday.

The U.S. Transportation Department's Pipeline and Hazardous Materials Safety Administration spokeswoman Patricia Klinger said her office had learned that the pipeline may have been used to carry heavier crude.

"I just found out that apparently, and the regional folks just found out, there is an interconnect on the pipeline that possibly does carry some oil out of Canada," she said in response to a question about tar sands crude in the pipeline....

Tar sands crude may cause more wear and tear on pipes because of its chemical makeup, including corrosive and abrasive agents, said Tom Finch, the pipeline administration's technical services director for the western regional office.

Federal inspectors were trying to determine if transport of tar sands crude could have triggered internal corrosion that may have played a role in the rupture, he said....

Richard Opper, head of the Montana Department of Environmental Quality, said he was surprised to learn the pipeline buried in the streambed of the Yellowstone may sometimes have moved tar sands crude from Canada.

"If the question is, did we know it was carrying tar sands oil? Hell, no," he said in an interview on Thursday.
