There are several things that are being done.
We have a master agreement with Alaska Railroad and we're partners, so in effect we're already operating up north, and some of the mitigation practices we're getting from them. We're also looking at mitigation practices that were in the Middle East in order to preserve camel herds.
You have certain numbers of bridges that you could build specifically for wildlife. You can have a kind of angular approach as opposed to just straight lines, which tend to confuse the caribou.
All of this is under development with engineering, but it's going to be substantial in terms of how little impact we're going to have once this is built.
JP, do you want to add anything?
