Of the 50% that are referenced in the Gazette publication, there are a number of control technologies that are available to the metal-plating sector as a whole. Basically it's a bath that they put the metal plating in. There's an option where you put a closed cover on top so that the fumes don't come out of it.
Fifty percent of that industry sector is using a fume suppressant. The other half is using the other technologies, like a closed cover or other control technologies. Of the 50% that are using a fume suppressant, virtually all of them are using PFOS. There is 50% of the metal-plating sector that we anticipate is using a PFOS substance, but all of them are using the fume suppressant. Because of the distinct and unique operations within that industry sector, they have to use a fume suppressant--it is an essential qualification.
The EU recently published a directive in December 2006 that did reference the chromium and metal-plating sector as an exemption. Although the U.S. EPA has not published an exemption for the metal-plating sector, it is under consideration under the 2006 significant new use rule that they published in 2006.
