Why wouldn't some more suggestions be made?
Also without a list it's hard to make a judgement on the nature of the conditions don't you think?
One condition could be that the number to call in case of an accident that would get posted on signs must connect to a service that has round the clock French and English service.
Another could be about the size of the posts that mark a river crossing.
Or to set a standard for the education of preschool day care for the families of pipeline workers.
I bet most of the conditions are minor things, unrelated to an engineering problem. I would expect that a pipeline company would have a firm grasp on the mechanics of a pipeline
You're right that the details matter - it could be 209,000 conditions and it wouldn't matter if they are so generous as to not have any meaning. The devil is in the details.
For example:
Alaska requires companies to have a response plan capable of dealing with spills of up to 300,000 barrels. In Canada, the current requirement is only for spills up to 70,000 barrels. To put that in persepctive, Exxon Valdez spilled up to 750,000 barrels and the ship was capable of carrying over 1.4 million barrels.
Alaska requires spill responders be able to reach the spill site within 72 hours, while Canada allows 72 hours
plus travel time, which can more the double the response time.
Another example would be a recent US decision that Oil Sands bitumen is not really "oil" and therefore pipeline companies are exempt from a requirement to contribute to the federal "oil" spill clean-up fund when they transport it. All despite the fact that Oil Sands bitumen is more harmful to the environment and more difficult to clean up.
As to your last comment about engineering requirement and your expectation that oil companies would have a firm grasp of how to build a pipeline- well really at issue is the standard to which the pipe should be built. Should it be the absolute minimum legal standard? Should it be able to withstand an earhquake? If so, of what magnitude? Etc, Etc.
Federally-regulated pipeline safety incidents (fires, leaks and spills) have doubled in the past decade, totalling 1,047 incidents between 2000 and 2012...one incident per every 500km of federally-regulated pipeline. Leaks and spills alone trippled. And that's only federally regulated pipes - i.e. the ones that cross provincial boundaries.
British Columbia had the most incidents at 279. Alberta was #2 with 244, Ontario was 3rd at 146.
So I think people have healthy reason to doubt that the oil companies have it all under control and nothing bad could happen.
