Enbridge finds more leaks in Norman Wells pipeline

http://www.cbc.ca/news/canada/north/story/2013/03/18/north-enbridge-normanwells-...

A third leak has been discovered along the Norman Wells Pipeline. Enbridge said it discovered contaminated soil in two spots along the pipeline west of Fort Simpson, N.W.T., last month. The pipeline company said the leaks were discovered because of a new program it's using that allows workers to look for small amounts of oil.

These are not large free flowing spills, it said. The company said they are releases of oil from the pipeline into the ground and so far they've been easily contained.
Pehdzeh Ki Contractors has been hired by Enbridge to bring the contaminated soil in dump trucks to a landfill in Fort Nelson, B.C.

One of the contaminated sites is about 120 kilometres west of Fort Simpson. The second is around 60 kilometers west of the community. The 869 kilometre pipeline runs from Norman Wells to northern Alberta.

Brad Enge with Pehdzeh Ki Contractors thinks an excavator came into contact with a pipe. “The pipeline was shut down when they were doing the digs of course, so there might have been some residual crude in the pipeline that leaked out into the ground,” Enge said. “They dug up all of the ground and probably took about four of times more soil than they really needed.”

Enbridge’s Graham White said it can't confirm what caused the leak. “We don't know. That's part of an investigation and a part of the information that we gather when we are doing our maintenance and repairs and that will come out in our investigation and that of the regulators,” he said. Both the National Energy Board and the Transportation Safety Board are involved in the investigation. So far, there haven't been any reports of damage to wildlife or water.

Enbridge has added sleeves to the areas where the leaks happened to prevent any more oil from leaking out. It is also updating the National Energy Board daily on the status of the cleanup.

    • Cancel the pipeline, we'll build a couple refineries right here in Alberta. Having th
      E price for gasoline go up everytime there is even a
      Whiff of a hurricane is ridiculous, plus they rip us off on the price of our oil too.

    • The pipeline first started flowing oil in 1944. So that's 69 years that pipe has been flowing oil. Maybe if the gov. would start making some kind of effort to start fixing the infastructure. Or at least form a agency to check these things we'll keep seeing this kind of stuff. We can't rely on these companies to fix things own their own. Gas lines, bridges, steam pipes, you name it.

      The construction of Norman Wells pipeline started in the late 70s after 20 years of environmental assessment and review. At the time it seemed like a boom to the Northwest Territories economy, because we didn't know any better. However, Enbridge has not done a good job monitoring this pipeline. They claim it's hard to monitor it due to it's isolated location, which is built mostly on the tundra in the middle of nowhere. But it is the land caribou used for migration and these leaks have contaminated that land. The caribou are a major food source up here.

      The Harper government pretends to care about the environment, but their 2012 budget eliminated Fresh Water Monitoring and cuts Environment Canada's budget in half. They have also laid off half of the government scientists and have silenced the rest. No one in the federal government is allowed to speak out against the Tar Sands. When the leader of the Opposition Party visited Washington recently he was accused of being unpatriotic because he apparently told Nancy Pelosi that not all Canadians were in favor of the Tar Sands.

      The government has also threatened organizations like the Canadian Wildlife Federation that if they campaign or inform the public about the impact the Tar Sands are having on the wildlife, they will lose their charitable status.

      I agree with your comment about these older pipelines not holding up forever and that they need to be monitored and replaced when required. However, even though Enbridge claims there was no cover up of the two other breaks that they were cleaning up when they discovered the new break, they do not have a good record in rapid responses to the oil spills.

      By the way, where are the ones located that you mentioned started flowing in 1944, as I am not aware of any other completed pipelines in the Northwest Territories? They have been discussing building a Mackenzie Valley Pipeline, and the federal government is trying to push that one through before the environmental assessment is completed. But I never heard about any older ones.

      Thank you for posting this video. The sad thing is that it is worse now then when this video was made. If just the pictures of what the Tar Sands actually looks like doesn't scare the bejesus out of people then they either need glasses or their heads examined. I would love to ask Harper how many more of us have to die before you understand that oil for the sake of oil isn't the answer.

      It is when they keep lying and telling the public that pipelines are safe. Especially when the Canadian government is pushing the American government to approve the XL Pipeline that will carry the dirtiest oil, where if a pipeline leaks it will be even harder to clean up then regular crude oil.

      The oil extracted from the tar sands has already had an impact on northern Alberta and the Northwest Territories, which had resulted in mutant fish and extremely high cancer rates, that is only getting worse. I would think that others would not want to experience what we've have gone through, since the development of the tar sands.

    • The dilbit production in Alberta is about 1.6 bln barrels. The aim for production is 6 bln barrels by 2030. How many more pipelines are needed to achieve this goal? 6 more? It's got to stop. Pipelines are not cheap means to transport. Just hidden from view (and inspection).

    • Of course they leak! Anyone who knows anything about pipes knows they can and WILL leak. It's the same with water pipes, sewer pipes, natural gas pipes. They fucking leak! There's no way to stop them. These companies are lying when they claim the pipeline will be safe.

      Absolutely. I was a city councillor for seven years and part of my job was dealing with our city's infrastructure. There is NO way to stop pipes from leaking, no matter what these companies try to tell us.

      Yes. And in any case, there is NO way they are going to provide the level of monitoring and maintenance necessary to minimize the chance of leaks. And there's no way they're going to replace the whole damn thing as soon as the level of wear indicates it will start leaking. To do so would be outrageously expensive. They will do the bare minimum they can get away with, and continue to lie to us that it is safe.

      Yes indeed the leak. I was once involved with connecting sensor clusters to telemetry data lines. This was on a high pressure natural gas line. They had sensors every 5 miles for leak isolation. They were pressure and vapor detection sensors. They knew it would leak eventually. If they had a pressure drop the motorized valves would shut. That is assuming the system worked. It sometimes didn't.

      Excellent information, wyley. They sure have been known to fail - every year.
      Now imagine that pipeline stretching over many 1000s of miles or barren, frozen tundra - where no one lives (anyone who could call an alert) - the frost heaves alone cause all sorts of problems in our North Country.
      The fact that Enbridge failed to even check out an "alarm" on the Kalamazoo line for almost 24 HOURS is criminal; I'm surprised that the NTSB hasn't charged them that alone - altho', it sounds like the most recent critique from NTSB, telling them that their "clean up wasn't good enough" is coming pretty close to criminal charges - hope so.

      In my case the line was only 100 miles approximately and the operators used to call and request testing to verify the trouble. One thing they did not do, in my example, was deny that there was a possibility of leakage. Their function was to catch the leak before it became a problem. Natural gas leaks tend to explode if uncorrected.

    • Enbridge is also the company pushing to build a pipeline from Edmonton, across the northern Rockies, to a seaport on the BC Coast. All shipments are bound for China. (We think, at least so far, that this one will not go through - it's not politically expedient for the BC Gov't to allow it - they're up for election in May, and 85% of the population is against this one.)

      They are a highly irresponsible company - as evidenced by their lack of response (17 hours) when a huge break in one of their lines poured over 700,000 gallons (20,000 barrels) of diluted bitumen into the Kalamazoo River in Michigan. In the first link below, it says "Operators didn't know HOW to respond to alarms." DUH.

      Also at this link:

      "Enbridge pipeline controllers in Edmonton ignored repeated leak warnings for 17 hours before shutting down a pipeline that poured 20,000 barrels of oil into the Kalamazoo River in Michigan in July 2010, says a report from the U. S. National Transportation Safety Board .

      A school bus length section of the pipeline ruptured on July 25, 2010, pouring more than 20,000 barrels of diluted bitumen into a 60-kilometre stretch of the Kalamazoo River."

      And from recent item (4 days ago) in The Province newspaper (BC)

      More than two and a half years after a pipeline rupture spilled heavy oil into the Kalamazoo River in Michigan, the U.S. Environmental Protection Agency is ordering Calgary-based Enbridge (TSX:ENB) to dredge the river to remove submerged oil.

      The agency says it has repeatedly found oil in sections of the river, and it wants that crude removed before it flows downstream to areas where it will be more difficult or even impossible to clean up.

      The agency is also ordering Enbridge — proponent of the controversial Northern Gateway pipeline through northern British Columbia — to maintain sediment traps throughout the river to capture oil outside the dredge areas.

    • Hardytoo:

      Thanks for the added links regarding the problems associated with this company. They took a long time to discover the first two leaks on the Norman Wells pipeline. This has contaminated land used by migrating caribou. I don't think they will be able to completely clean it up no matter what they say. Also. even though they are cleaning it up now, the leaks were discovered a while ago and they tried to lie about them.

      That's so sad.
      Wasn't it John McCain (during his attempted election campaign) when he extolled the virtues of adding more northern pipelines - I seem to recall he said something to the effect that the "caribou just love to hang around those heated pipes.. to warm up...." - what an incredible crazy statement from a crazy old fart.

    • There is a vote coming up soon in the Senate to decide whether or not to proceed with this pipeline here in the Gulf. I just wrote my senator, again, and demanded that he vote against this disaster-waiting-to-happen. I hope he listens this time.

    • Correction: Enbridge is the company under consideration to build the North Gateway Project to Kitimat, BC, an alternative to the XL Pipeline. TransCanada wants to build the XL Keystone Pipeline. But these companies are all the same. Enbridge is also the company responsible for the major oil spill in the Kalamazoo River in Michigan in 2010.

      I do not understand why the media doesn't cover this more. It's like they seem to think that the so-called benefits of pipelines outweigh the major impacts they have on the environment. Of course, the MSM is owned by corporate America, who controls the message.

      The media is no longer the "freedom of the press." Just like our elected officials, they have been bought off. They will spend the next month discussing the election of the pope, or the Arias murder trial, or the weather. But they avoid keeping us informed, or worse, they downplay the issue of global warming - it's not so bad - and despite loss of support from the communities they are supposed to be reporting to, they continue to do the bidding of Big Oil, Big Banks and Big Industry. It's shameful.

      "Of course, the MSM is owned by corporate America, who controls the message." There's the answer to why media isn't all over this. There's a reason the government allowed more and more media ownership by fewer and fewer hands. The corporations bought the pols and the rules got changed so the corporations could control the message.

      And the world has gone to hell so much faster since that happened. Democracy? Not without an informed public. National laws? Not so much, not since all those 'trade agreements' that basically override any nation's laws if the corporations decide the laws inhibit 'trade' (trade being whatever the frack they want to do).

      Corporations, Big Oil, Media, all owned by the same Hoarder Class 'shareholders' who also profit from war and famine. It's class warfare and it is global.
