The federal government could address the use of mercury-emitting fuel under CEPA, if it wanted to. It hasn't yet, but it could.
Can I speak to the issue of virtual elimination for a second? I think there's a little confusion there.
The federal government, under CEPA, has banned a lot of substances. So to say that we haven't virtually eliminated anything is a little misleading; we've banned substances, which goes well beyond virtual elimination. Virtual elimination is a concept that relates to virtually eliminating the release of a substance. That's not as strict as banning a substance. So we've gone beyond virtual elimination in a large number of cases.
The act sets up a very complicated regime for virtual elimination. The main reason the regime hasn't been used, frankly, is that it's very complicated and imposes what I think have been judged in the past to be unnecessary additional steps that add no environmental or health value. If you ban a substance, what's the merit of adding it to the virtual elimination list? So we haven't added DDT to the virtual elimination list. Should we? That would be a process step that has no environmental or health benefit whatsoever, because it's banned.
