Thank you very much.
I have just one very short question. On Tuesday, we had testimony, and I can't remember it came from, but I just wanted to raise it. It's on the implications with respect to the tailings ponds in the oil sands. The testimony indicated that not only was there a leaching issue--obviously into the aquifer would be of concern--but also the possibility of a Hungary-type surge from those tailings ponds that could be very devastating.
The question was raised whether there was an accountable regime in place that could anticipate and look at that nature of environmental tragedy, if you will. Would you like to make a comment on that?
