Ms Sarah Neary:

I suppose where a quarry produces a concrete block or aggregates that are covered by a harmonised standard then they fall under the construction products regulation, CPR, which places significant obligations on the operator to create a declaration of performance or DOP and carry a CE mark. When it comes to construction products it is a subset of all of the quarries that are in the country producing that, and that is where market surveillance, and all of the structures that come under the CPR exist. That is a subset.
