Thank you.
I want to turn now to the federal contaminated sites. Again, in the supplementaries here we have some additions to that, but I do know that this is actually a very large plan. It's a 15-year plan. I'm wondering if we can have a bit of an explanation as to where we are on the plan, what we've spent to date, how many sites we've cleaned up, and where our focus is for the next little while.
