Oil Pipeline Spill History at the National Energy Board of Canada Library

This week, I am taking advantage of some of the historical research materials available at the National Energy Board library in Calgary, Alberta. As we discussed on a recent episode of Nature’s Past: Canadian Environmental History Podcast, federal department libraries are incredible resources for environmental history. With the closure and consolidation of so many of these libraries across the country, I wanted to get to the NEB library before any materials got lost in the shuffle.

The trip to Calgary paid off almost immediately. I am currently working on a history of oil pipeline spills in Canada and I wanted to get a broad picture of the frequency of pipeline failures on Canada’s interprovincial and international oil pipeline network. The helpful staff at the library dug through the catalogue and we turned up this:

Pipeline Incident Database Binder

A binder full of every pipeline incident reported to the National Energy Board between 1959 and 1996.

This was exactly what I was looking for. The binder contains 325 pages of every pipeline incident reported to the National Energy Board between 1959 and 1996. Page after page of spreadsheet charts include dates, locations, incident types, causes, quantities, product types, companies, and annotations for all reported pipeline incidents. This includes every oil pipeline spill. It is basically the mother lode.

I posted a couple of examples to Twitter as I browsed the binder before copying the entire thing:

Unfortunately, we could not find a digital copy of the database. That means that I have a very large data management problem on my hands. I have scanned the entire database and run it through preliminary Object Character Recognition software. I will then need to manually plug in the entries into my own spreadsheet file so that I can make the data usable. Once I do this, I will be able to show the following:

  • Total number of oil pipeline spills between 1959 and 1996 along with annual totals
  • Total volume of oil spills (for entries that include quantities)
  • Locations of pipeline spills over time by province and lines
  • Breakdown of oil pipeline spills by company
  • Causes of oil pipeline spills over time

I am also interested in manually exploring the qualitative data in the comments for each incident. As my Tweets from earlier this week reveal, the contextual information in the comments show many of the different (and sometimes bizarre) circumstances that result in oil pipeline spills, including mudslides, flying boulders, and human error. This is especially valuable because newspapers only seem to have reported on a fraction of these incidents.

In the meantime, I have been able to compile a broader history of pipeline incidents from the annual reports of the National Energy Board. The board first started reporting pipeline leaks, breaks, malfunctions, and other incidents in 1965. From this information, I was able show the history of pipeline incidents from 1965 to 2013:

NEBPipelineFailures 1965-2013

While not every incident resulted in an oil spill, the data point to a bigger picture of the degree to which Canada’s interprovincial and international pipeline system was subject to a multiplicity factors that resulted in workplace injuries, deaths, explosions, and commodity leaks. Hopefully this history of oil pipeline spills will help Canadians better assess the risks associated with the transportation of large volumes of hazardous materials across the country.

My experience this week has also underlined the importance of these federal libraries. Access to the NEB collection at Library and Archives Canada is restricted and requires the completion of the time-consuming freedom of information process. The library holds materials that are easy to access and may not even be kept in LAC. That big binder of pipeline incidents was sitting on a shelf on 7th Avenue SW visible from the street. Who knows what other materials of historical significance are sitting on department library shelves?

Readers can learn more about this project at 2pm on 13 May 2014 at the Deer Park Branch of Toronto Public Library where Professor Kheraj will present some of his findings from this research. Details are available here.

    This kind of information would be greatly useful for planning departments when zoning residential areas around these kinds of pipelines. For example, the City of Gatineau is planning the development of high rise apartment buildings around a natural gas pipeline in our area. While it may seem common sense to some that this is a dumb idea, City staff don’t see it that way unless there is information to prove otherwise.

    Yes, knowing the location of gas pipelines would be handy for planning departments. I still have to sort out the location data in these documents. I’m not sure how precise it is.

    Do you have information on what was done to clean up the spills, or do you need to look somewhere else for that?

  4. Sean Kheraj

    V. Jobson:

    In some cases yes and in others no. Sometimes the records include details of recovery and remediation. The best information comes from Transportation Safety Board investigations into major spills in the late twentieth century. The big binder and newspaper reports sometimes include notations that X quantity of oil was recovered. I need to do more research on standard recovery practices. I do know that in some instances in the 1970s, surplus oil not recovered was burned. This practice ended in the late 1970s.

    Not much detail on long-term impacts. In the 1970s, soil scientists at University of Alberta became interested in the impact of oil pipeline spills on agricultural land. And some fish and wildlife officials and activists became concerned about wetlands and muskeg environments around the same time.

    These are definitely areas of interest for me. I’ll be sure to post more as I find it.

    If you have a reference for where I can find these data, I would greatly appreciate it. Please share it and it would save us a lot of time crunching these numbers. Thus far, I have had little luck. I’ve been working with librarians at the NEB library and Library and Archives Canada. When I published this article, I received requests from intervenors in NEB hearings who have also been searching for these data.

    The link Rob provided in the comments thread is to a Global News report on oil pipeline spills in Alberta along lines regulated by the province’s former Energy Resources Conservation Board, not the National Energy Board. The ERCB only regulates pipelines within the borders of Alberta. The NEB regulates interprovincial and international pipelines in Canada. I’ve written about this previously here:
