Thank you, Mr. Chair.
If I don't use my full amount of time, I'll be deferring some to Mr. Calkins.
Welcome to our witnesses. We are currently studying the oil sands and their impact on water.
We've talked quite a bit about water quality today. We haven't talked very much about changes to the topography. We did a flyover as a committee. Those of us who were there actually participated in a flyover, and we got to see some of the reclamation work that has commenced. We are told--although they have yet to quantify for us how much--that the pace of reclamation will be increasing over the short term.
But even with reclaimed land, if you will, and with reclaiming the tailings ponds, for example, there are changes to the topography. The wetlands are not in the location that they were. You're changing the physical geography with these tailings ponds--stacking.
What impact does changing the topography have on the movement of water in the basin?
