Mr. Feargal ? Coigligh:

Before I get there, the Donegal audit that was produced today showed the system working. The NSAI discovered a problem. Ms Phelan has spoken about the audits and the programmatic approach to market surveillance and testing the NBCMSO is doing. The Minister requested an audit, which pointed out more room for improvement. There are still issues with compliance with paperwork. There is still more work to be done.

I will ask some colleagues to come in on the number of quarries that are operating in the State at any one time. Quarries can open and close and they can operate for different products. All quarries do not necessarily provide products for concrete blocks. It is quite a big picture. One of the recommendations from the report on the Donegal quarries is that there would be a national register. The GSI has some information on that. Perhaps Mr. McGrath could provide what information he has on that area.
