From my own experience, what we've seen in regulatory practice recently as a result of Lac-Mégantic is a reduction in speeds in CMA limits, in highly populated areas. That alone will not fix the problem. If we're going to continue to transport oil by rail, which I think can be safe, we're going to have to have stricter regulations on maintenance. I see that in what we call “dark territory” where there are not bonded rails, so the engineering services go out to patrol the track.
With the pipelines, I'm not familiar with the process and I couldn't comment effectively on that.
