Issues Relating to Quarries and Deleterious Materials: Discussion

Mr. Eoin McGrath:

I guess that is a question for us Deputy. Yes, we did. That is the first thing we do. We have essentially a methodology for when we are looking at quarries when we are requested to provide technical assistance. The first thing we do is look for the geologist's report. We go through that and evaluate it to see if it makes sense and reflects what we know of the geology based off our own mapping of our aggregate potential products and then, based on that, we assign a priority for inspection to a particular quarry. By way of example, one of things we would look for would be caveats in the geologist's report and whether the geologist identifies it as a significantly variable lithology or if they identify areas of trouble. If that is the case, that would be somewhere which obviously is of higher priority for a visit than some place where the geologist says the same material is consistent across the geology.
