The short answer is absolutely. We have a long history of building pipelines in a diversity of environments, including many stream crossings. Yes, the technology exists. We know how to do this, and one of the really unfortunate outcomes of the Mackenzie process—over and above the fact that it took so long and may well have an impact on whether that project ever proceeds or not—is the fact that we went over and over the same issues in a multitude of forums with a multitude of people. And that in no way is a representation that those issues should not be addressed. What we need to do is find an efficient and effective way to address them and make sure they are addressed to the satisfaction of the key stakeholders and the regulator, and then move on.
We keep recycling and going over and over things that frankly are well established and we've already done justice to in terms of addressing the issue.
