Alberta pipeline spill releases 1,300 barrels of oil, Canada - 20th July 2011

Another northern Alberta oil pipeline has been shut down after operator Pembina Pipeline discovered a leak in a remote area north of Swan Hills.

An estimated 1,300 barrels were released from the underground pipeline onto muskeg and into a creek before the Calgary-based company shut down the line, said Pembina spokeswoman Shawn Davis.

"We detected a volume imbalance at our control centre and from that we initiated air and ground investigations," Davis said Wednesday. "And from there we found that there was a leak."

The pipeline was shut down around 7:45 a.m. Tuesday when the system showed a dip in volume, and the oil spill visually confirmed in the evening, she said.

The Moosehorn gathering system was flowing an average of 5,600 barrels of oil per day prior to the incident. Pembina has arranged for shippers to move volumes by truck to nearby truck terminals, Davis said.

Representatives of Alberta Environment, Sustainable Resource Development and the Energy Resources Conservation Board have been on site since early Wednesday to ensure the leak is contained and to start cleanup efforts, said Darin Barter with the ERCB. Read More
