In terms of self-assessment, and here we're essentially talking about screenings—there's been a lot of discussion about the thousands of screenings that take place that aren't significant—I would say there has to be a great deal of care not to throw out the baby with the bathwater, because it is entirely possible to have a small project with a significant environmental impact. So there needs to be a very clear sorting mechanism. Some of the mechanisms are in the act and just haven't been used properly—class replacement screenings, for instance. The exclusion list has not been adequately used.
But there was an attempt under the CSA to come up with a Canada-wide standard for environmental assessment that would have laid the groundwork and to a large extent did. It was quite well developed at the point where it was terminated. I would suggest that would be a good starting place for this discussion.
