You would have a set of ambient air quality standards, so those would use the same type of measurement as do our current Canada-wide standards, although hopefully they'd be stronger than the CWS's. You would have ambient air quality standards and measuring stations in different parts of the country. We already have these for the most part to measure air pollution with. If a certain zone fell below the ambient air quality standard—so below the standard that is in the air—you would have a set of emission standards that would be associated with the ambient air quality standards. So if you fell below the ambient standard, that zone would have to adhere to a particular emission standard from the facilities that are emitting pollution in that area.
The United States works roughly on this basis. They have a county basis. They're called attainment zones. The federal government puts out ambient standards. Each state has to come up with plans in order to meet those standards. If the plans are inadequate, the EPA steps in and says the plans are inadequate. The enforcement mechanism would be quite different in Canada. In the United States, the enforcement mechanism is, in essence, infrastructure funds. In Canada, I think there are different mechanisms we can use to have the provinces run things from that perspective. Then you have the federal government in more of a backstop role.
Does that answer your question?
