Yes, I can use a specific example, and it's a timely one, as a matter of fact. Right now both the provinces and the federal government are working to develop new air quality standards for conventional air emissions. I'm not talking about greenhouse gases; I'm talking about conventional air pollutant emissions from a number of industrial sectors across the economy, and clearly refining is one of those sectors.
One element of that effort is to advance some federal minimum standards for refinery emission improvements. In the consultation exercise we're looking at a number of models under what's called the air quality management system, or AQMS, which is the effort being led federally by Environment Canada. We're looking at a number of models and options specifically with respect to refineries and what's called the base level industrial emission reduction, or BLIER. I don't want to get into all of the acronyms. From an industry perspective, what we have been advancing and advocating is a system that is very much an outcomes-based process. It's the bubble approach: we put a bubble over a refinery and then, using a system that we've called the national framework for petroleum refinery emissions reductions, we determine the performance outcomes for various pollutants at refineries. Mr. McGuinty, you probably might know about that from your days when you were at NRTEE.
We're advancing a system that lets us establish the performance outcomes for various pollutants at refineries. What we're hearing as an alternative from Environment Canada is a very prescriptive one that sets out what each individual piece of equipment needs to do based on a specific technology. It's very much focused on a prescriptive approach that leaves very little flexibility and in fact drives performance improvements that are far greater than we think is in the philosophy behind AQMS. It certainly would require Canadian refineries to make investments that would bring levels of improvement that far exceed what's happening in the U.S.—
