Thanks.
You spoke in your brief about fairness and competitiveness and the cycle of capital stock turnover. I'm well aware of those arguments, because I sat with your association for 10 years on the Canada-wide standard for coal-fired plants and the Alberta negotiations on regulations for mercury.
The argument that was continuously put forward by your association was that we can't possibly regulate mercury, because it's not affordable and the technologies are not provable. Yet in the end, the Government of Alberta, to their full credit, actually issued a regulation, which will mean that all the coal-fired power plants in Alberta will be capturing mercury this January.
Do you think it's quite conceivable that the same scenario will play out that we discovered on mercury, that in fact technologies for the control of carbon may be far more affordable than forecast?
