Yes, sure. One of the latest examples we have was the latest multi-sector air pollutant regulation that came out, where some, for example, testing done under the provincial government may not be accepted under federal regulation, so now we're going to have to go back and retest, and it could be just because it's a test method that was not initially in the regulation. It could be that the boiler doesn't have a sampling port, so under the provincial government we sample somewhere else, but we can't do it under the new federal legislation.
Those are examples, from when the legislation was written, that create duplication and then duplicate enforcement, because when you go in, you're doing a certain method and the other one does not.
