We pushed the Canada-wide standard on ozone and on particulate matter. In fact, we went to our own provincial environmental appeal board on that Canada-wide standard, and so on, to the point where the province now includes that standard in its technical assessment when it issues a permit for pollution. They just assess that this will never violate the Canada-wide standard, because it's so generous that any new polluter isn't going to violate it anyway.
