Okay. I'm hoping to get to a couple of more questions if I can here.
With respect to acrylonitrile, what we learned in the government's response is that 99% of emitting sources are covered, and we're talking about two companies particularly. One is federally regulated. The other is provincially regulated. Yet you still conclude in paragraph 1.13 that Environment Canada should ensure control measures are in place to deal with significant sources. I'm asking you what more should be done with respect to acrylonitrile risk management for the additional 1%, or are you not satisfied that you can audit the results at the provincially regulated plant?
I want you to keep in mind as you answer that the chemicals management plan will be sending thousands more chemicals down the line for risk management to Environment Canada. So at what point do we draw the line and say 99% is good enough and let's move on to another? Could you inform us?
