Ms Mair?ad Phelan:

When we commenced the work on the 2021 market surveillance strategy we did a very extensive desktop study on where every single hole that produces aggregates or rocks in Ireland was. We looked at the websites of the EPA and the GSI. We identified something like 1,800 of what could be termed quarries and of that 1,800 as many as 500 actively produced products, some of which are not construction products. Of that, as part of our 2021 market surveillance strategy, we visited 20% and identified the main producers of the aggregates, which go under floors, and the aggregates for blocks, lintels and concrete.
