There are very good legislative tools that have been put in place to govern operations in the Arctic. Canada's fantastic Arctic Waters Pollution Prevention Act, and the legislation that goes around that defining legislation, is very good. Right now, vessels operating there are required to carry some standard form for controlling a spill and must at least start the cleanup of a spill if a spill happens.
I think the release of pollutants through an incident, a collision, or a sinking is probably the largest problem to deal with in the Arctic in terms of the dispersal of oils, chemicals, or pollutants. If we're going to build a presence in the Arctic in terms of infrastructure, whether it be bases or enhanced dedicated facilities that deal with either search and rescue or spill cleanup, that's what has to happen. We have to enable certain vessels or certain boats to respond very quickly to an event like this. Either develop the technology to do it or do the research into how we can contain the spill. Significant work has gone on. I think it's a worthwhile pursuit.
