Very briefly, I think what was just said is certainly correct. Those contaminated sediments are certainly the legacy in the sense as well that they remind us why we need to take those preventive steps. In my breaking down, in what I thought was a helpful way, the talk into retooling and new facilities and then substances in commerce, perhaps I should have added a third, which is how virtual elimination deals with those kinds of sediments. We certainly know from remedial action plans and other instruments under the Great Lakes Water Quality Agreement and also issues around dredging of the Lachine Canal, etc., what the costs are and how controversial it is and what a huge difficulty it presents.
