As you say, I don't have the clear answer on whether the exemptions for the chrome-plating and electroplating sectors are rational. There's a contradiction internationally, where the U.S. originally did not exempt it and is considering exempting it now; the EU is considering exempting the sector; the international ban at the moment, which is widely supported, will not exempt the sector; and the U.K. has no plans to exempt the sector either.
What having virtual elimination on top of these prohibitions with exceptions will do—and again, we're talking about prohibitions that are allowing people to still use PFOS in these sectors—is deal with the emissions from those sectors, if we are going to allow this exemption to go forward. I think it still needs more study and some transparency. We need to at least be controlling the emissions from the use of those sectors, how PFOS is disposed of, and how much PFOS pollutes when the platers are using it.
