With respect to the Great Lakes Water Quality Agreement, when you come back, it's about restoring the beneficial uses, and there are criteria for doing so. With contaminated sediment, the effects are still showing up in the wildlife. We've gone from gross effects to much more chronic, long-term effects at much lower levels. Arguments can be made--people can detect stuff to 10-18. What does that mean for a biological end point? No one really can answer that question at this point in time. The effects are still showing up as they are. So the position, really, at the time was virtual elimination in the process--get it before it gets out there--and use the strategies and technologies then to change those processes. That's really what the strategy of virtual elimination was all about with respect to the commission, not the aftermath part. They realized at that time that was not realistically possible.
