It's the Minister of the Environment who would make that determination, based on evidence and research and the science from the community at large, both here in Canada and around the world. The body of evidence, of course, is unfortunately growing, because there are spills. Spill-treating agents are some of the new tools to deal with spills. Certainly there was extensive use of STAs in the gulf incident in the United States. Some of those circumstances are not present here. The water is warm and the nature of the water is different from the nature here. But there are other circumstances, for example, in Norway and the U.K., where the water is very similar to here. It's cold, and it's sea water, and it's a little bit rougher, if you will. They have examples in those jurisdictions and others where STAs are used.
