Mr. John Wickham:

During the generation of IS 465, a number of houses were tested to inform the decision-making process. Through the general consensus of standardisation, writing the first edition of IS 465 became what it is at this point in time. The emergence of more data that pointed towards something else happening really came to the attention of the NSAI in the summer of 2021. As I pointed to earlier, in April of that year the Department, through Geological Survey Ireland, commissioned open calls for research to explore issues to improve technical knowledge in this area but nothing was forthcoming with respect to pyrrhotite emerging as a particular issue. Once the NSAI committee received a body of evidence, it made a commitment to look into it further. Since then it has become the project that it is today. Research partners have been procured and the right experts are involved. We have had transparency in terms of how we correlate various expert results on it. The fruits of this will emerge in the coming quarters.
