Mr. Gerard O'Leary:
I believe the guidance refers to minimum distances. I remember that during the consultation process there was a desire to set at least some criteria. The Deputy should not hold me to this but I believe the word "minimum" is there. Things have moved on a great deal in the area of dispersion modelling and, regardless of whether we were to change the guidance, the modern approach to odour is to do dispersion modelling. One can do it much better than using an arbitrary figure because one can quantify the amount of odour that can be generated from a wastewater treatment plant and model it in different directions. A far better approach at this stage would be to model the activity as opposed to putting a set number to it.
