Allow me to suggest what this report says, and I'm quoting again: “During the period 1990 to 2005, there were 12,848 pipeline incidents reported to the EUB (not including test failures). Of these, 657 were hits with no release, leaving 12,191 resulting in a pipeline release”. That's industry terminology for “oil spill”. It says that of all of these “93.8% were leaks, and the other 6.2% were ruptures”.
Should that cause any pause for the people in northern British Columbia who are facing the prospect of another pipeline?
