Yes, I'll go first again.
I think CEPA already has powers that would allow that. Under section 93, the government can decide it wants to ban something, and if it does, then another substance would have to be used. So effectively we do have the ability to do that.
For products, I think section 93 is a part of the act that more logically fits, rather than using virtual elimination. I agree with what was just said—and I made this point in my remarks—that the LOQ for products is a very difficult thing to do. We're suggesting that it not have to be established for products. I think it isn't so difficult for emissions from plants, and it should remain there. But there is an issue about establishing LOQ in relation to products. It think it probably would make more sense if the government didn't have to do that; it would still retain the power to do so if it felt it were necessary, but it shouldn't be mandatory. And I think in most cases the government would probably choose to use the powers in section 93, which can have the same effect as substitution.
