I want to remind members, respectfully, that in fact this provision is independent of the creation of a clean air part or not. All this provision is doing is taking these substances off the list of toxic substances. It's doing so in conjunction with other provisions, which have not yet been voted on, which were stood at the beginning of the discussion of the bill, that would redefine those substances as air pollutants and as greenhouse gases.
The provisions that were reported yesterday, L-20, L-21.1, and L-19, do use those words. So essentially all you're doing is taking substances that have already gone through the process--set out in part 5--and have been classified as needing risk management of some kind...and today they're classified as toxic substances. Were this to proceed in the future, they would be called air pollutants or greenhouse gases. That can be done as part of setting up a clean air part or completely independent of a clean air part. Essentially all you're doing here is renaming them as air pollutants and greenhouse gases.
