I think our colleagues at Environment Canada don't say you're not allowed to do it, but you have to do it by the provisions of the Canadian Environmental Protection Act and the ocean dumping regulations.
Certainly in a lot of the dredging we've been doing in most cases in Atlantic Canada now, very little is being ocean-dumped any longer because of the regulatory regime, and a lot of it's being land-filled. I know in the Newfoundland and Labrador region, for example, we get permission from the provincial authority to bring our dredged spoils, if they're not contaminated, to municipal landfills. And it's working out pretty effectively, because the provinces are trying to consolidate their landfills, so ground cover is welcome in many respects. But the trucking costs as they consolidate their landfills--and there are few of them--and the cost of dredging are going up, and it's likely to be the case in the future, I would think.
