Mr. Declan Burke:

Gas Networks Ireland undertakes the risk assessment and has identified a minimum of 1.5 m from properties. The regulating station does not vent itself, per se. There is a device inside the regulating station called a relief valve, and that is what vents. Inside the station, we essentially run a pipe from that device externally to this vent stack, which needs to be a minimum of 1.5 m from a dwellings or a business, and, as I indicated, it has a height of 2.5 m. It is really about the vent stack.
