Previously, the way the department would have worked.... We have to remember that this was in 2017. Some of the studies were done in 2013 and 2014. We did notification on three bases. First was that if we knew there was an active treaty claim, then a notification would have been done, because it could affect the exercising of rights.
Second, if we were in divestiture conversations or transfer conversations, it would be disclosed. I'm not going to argue the point about whether or not we sufficiently disclosed through that process, because I don't think that it's productive and I don't think that's what the committee wants to discuss today.
Third, if we had studies in our possession that indicated that there could be a risk to human or environmental health, then there would be an engagement.
