I do not mean in any particular context. The Department would have been notified because we have been dealing with these problems for a long time, as I certainly have been in Mayo, given they were first identified, as the witnesses will know, in Erris and Belmullet and on the Mullet Peninsula. That was in about 2013. I heard pyrrhotite being mentioned at that time, actually in the context of incidents that were arising abroad, when we were trying to learn about what was happening when these houses were crumbling. Did the Department at that time not have reference to pyrrhotite?
