I can take that question.
With respect to deciding to make a specific regulation under any of our legislation, we have to look at whether there's a likelihood of a source that is not currently controlled. In this case the Government of Alberta has a zero discharge permitting policy that is enforceable from their perspective. That's why my colleague Mr. Tremblay explained that they are looking at whether there is any seepage through the monitoring that's done to determine if that zero discharge permitting policy is in fact being implemented. All the information to date for us has said that, yes, that is the case. So there is not a release into the water that we would then be able to regulate.
The Fisheries Act, though, has that similar prohibition against a discharge, so it's a tool we can continue to use to ensure the zero discharge permits of the Government of Alberta are enforced.
