Mr. Chair, I would say that they're always in the midst of updating the sites, the experiences and the exposures that may have taken place as a result.
I know there was a question in the first hour that referenced whether we go back and look at sites from before, where chemicals that were used may have new links to potential conditions and cancers, or look at sites that were looked at differently when they were closed in a particular era and need to be looked at again. I think that's part of keeping it as a living list, something that can be updated. I don't think it will ever be entirely comprehensive and definitive, because it can always be revisited to add things that may have, after research, developed into different kinds of potential exposures as well.
