Perhaps I can address that issue. The issue of the demarcation between science and policy, or science and implementation, is a pervasive issue, and it's not unique, by any stretch of the imagination, to the SARA case.
You see this, for example, in the context of chemicals assessment in the CEPA context. You have on the one hand the more scientific notionally component, which is the risk assessment, and then you have the less notionally component, which is the risk management, and under CEPA, under the chemicals management plan, that is very clearly, in principle, demarcated.
I think that in response to your question on whether these are normal growing pains, I'd respond yes. As I said in my introductory comments, we're engaged in an experiment here, and we should not expect to get it right at the outset. I think that would be unrealistic and verging on the unreasonable.
