I think you have to come up with an understanding of what metrics you are using to evaluate whether or not those controls are accomplishing the risk management objectives they are outlined and identified to accomplish. I think CEPA has an inherent process that allows the government and Canadians to look back and evaluate the strength of those risk management options you've identified. I think we've done that in numerous cases. You've actually been able to demonstrate, and the government has been able to demonstrate, that there have been effective reductions. Sometimes those might not necessarily be to the degree that one might want, but I think there is evidence out there that CEPA demonstrates that you have the ability to assess whether or not that risk management activity is in fact accomplishing what it was designed to do, or whether a pollution prevention plan is working the way you intended it to. You have metrics in the system that allow you to make those determinations and to make a risk-based decision as to whether or not you have to continue with that course of action, change action, or implement another control if you find that the risk mitigation measures are not accomplishing the objective they were intended to.
