I think we could see providing a way off the watch-list when there is information to suggest that a substance is no longer capable of becoming toxic. However, I think the part that says one of the reasons you would take it off the watch-list is that it is determined not to be toxic under section 64 is problematic, because that's exactly the kind of circumstance in which you actually would put it on the watch-list. Perhaps you've gone through an assessment to determine whether it's toxic and perhaps the exposure is not such that it is going to make it onto the list, but you put it on the watch-list to signal to people that if they start using it more, they might need to assess it again and that it might become toxic.
