The coast guard used to be involved in dredging, but we do almost none of it now because of program review decisions made about a decade ago. The only places where the coast guard still does dredging are on the St. Clair River and the St. Marys River, near Sarnia, Detroit, and Windsor, where we have obligations under international treaties, and on a full cost-recovery basis on the St. Lawrence. But that's the only dredging we've done since the time of program review, when what had been a more extensive dredging program in the coast guard was ended.
