Massive oil sands pipeline leak spills thousands of gallons in the Canadian province of Alberta

Oil Spill Alert

CALGARY, Alberta – Nexen Energy apologized on Friday for an oil sands pipeline leak in the Canadian province of Alberta that is one of North America’s largest-ever oil-related spills on land, and said its clean-up crews were working around the clock.
 
The company, a subsidiary of China’s CNOOC Ltd., said it is still trying to find the root cause of the leak in the pipeline, which was new and installed last year. It found a visible breach about the size of a hand, which Nexen’s automatic detection systems did not pick up.
 
The incident is another blow for the environmental record of the oil sands industry, already under fire from environmental groups for its carbon-intensive production process.
 
“We are deeply concerned with this and we sincerely apologize for the impact,” said Ron Bailey, a senior vice president of Nexen who leads the company’s Canadian operations.
 
The spill was detected on Wednesday and leaked 31,500 barrels of emulsion, a mixture of bitumen, water and sand.
 
The leak covered 16,000 square meters and the Alberta Energy Regulator said it did not contaminate any water bodies. Nexen said the area has been isolated.
 
The volume is larger than the July 2010 rupture of an Enbridge pipeline which spilled an estimated 20,000 barrels of crude, with some reaching Michigan’s Kalamazoo River.
 
Still, because the spill was bitumen emulsion, rather than oil, it would be significantly easier to clean up and less damaging to the environment, said Raj Mehta, a professor of oil and gas engineering at the University of Calgary.
 
“It should not be contaminating any water table. Bitumen, because it’s so viscous, is like molasses,” he said. “You can literally back hoe and scoop it up.”
 
Alberta Premier Rachel Notley, who on Friday finalized a Canadian energy strategy with other provincial leaders, said the leak was “very troubling” but pipelines were still the best option for transporting crude oil.
 
“As much as everyone was concerned to hear it had happened, it did not actually in any way shake the conclusion by all premiers that pipelines remain the safest way to move hydrocarbon products,” said Notley, whose recently elected left-wing NDP government has pledged to toughen the province’s environmental standards
 
Nexen said restarting the pipeline, which connects its 9,000 barrel-per-day Kinosis oil sands project to Long Lake, will take “some time.” Production from Kinosis will be shut in until the pipeline is repaired.
 
Long Lake, which has capacity of 72,000 bpd but is producing about 50,000 bpd, is 22 miles southeast of the oil sands hub of Fort McMurray.
 
The largest Alberta oil-related spill on record, according to the AER, was a 40,000-barrel release from a pipeline operated by Peace Pipe Ltd in December 1980. More recently, a Plains Midstream Canada pipeline failed in April 2011, releasing an estimated 28,000 barrels of oil in the northwestern part of the province.

Freak September snowstorm causes havoc with major power outages in Calgary, Canada

More power outages expected as snow-laden trees continue to fall around the city

Thousands of Calgary homes and businesses are still without power after a freak September snowstorm blanketed the city, and officials are expecting some Calgarians will have no power overnight.
 
“We are still very much in an active situation,” said Mayor Naheed Nenshi.
 
Emergency responders and utility workers have been scrambling to deal with power lines downed by snow-laden tree branches. They expect work to continue into Thursday, and the cleanup could take days or even weeks.
 
“Don’t be alarmed if you hear chainsaws [tonight],” said Nenshi.
 
The mayor said the priorities right now are keeping Calgarians safe, restoring power and clearing the roads of debris.

Power outages expected overnight
The city says it is waiving tipping fees at local landfills for Calgarians to dispose of debris. Residents are being asked not to put broken branches in the blue recycling bins, green organic bins or black garbage bins.
 
There were roughly 200 reports of outages in Calgary on Wednesday. A spokesperson for the city-owned utility Enmax said the situation is very fluid, and more power outages are expected as more trees break under the weight of the heavy snow.
 
Enmax officials said they cannot put a timeline on when power will be restored to all parts of the city.
Grumpy snowmen
“September snow + bored = grumpy snowmen army
“This is actually in pretty much all quadrants of the city with the exception of the northeast,” said Enmax spokeswoman Doris Kaufmann. “It has been the least touched. Enmax has brought on additional crews to assist with all of that effort getting the power on.”
 
Nenshi asks those in affected power outage areas overnight to check on the welfare of their neighbours, especially the elderly.
Emergency centre opened
City officials say there are scattered phone outages in the south end of Calgary. If a resident has no phone access, they can attend any local city building to get help.
 
Emergency crews are busy responding to reports of sparking and smoking power lines. City officials say if you see a downed line call 311, and if you see a sparking line call 911.
 
The city opened its Emergency Management Centre to co-ordinate calls. 
 
Officials said crews are having to prioritize and respond to the most urgent situations.
Police and fire crews are taping off areas where there may be a risk to people, such as a power line lying across a road.
