The matter referred to in the question is an operational matter appropriate for Gas Network Ireland (GNI) and not one in which I have a function.
GNI is mandated under Section 8 of the Gas Act 1976, as amended, to operate, develop and maintain a national system for the supply of natural gas to all customers connected to the network. GNI is a subsidiary of Ervia of which the corporate governance responsibility falls within the remit of the Department of Environment and Local Government.
I have asked GNI to respond to you directly. If you have not received a reply from GNI within 15 working days, please contact my Private Office and my officials will follow up.
