Vol. 467 No. 7
408 Mr. Callely asked the Minister for Transport, Energy and Communications the possible health and other side effects from leaks and lost gas in the Dublin Gas network; the concerns, if any, that have been brought to his attention in this regard; and if he will make a statement on the matter. [14099/96]
Gas leakages from the old gas network, taken over by BGE in 1987, have been reduced to a level comparable to the best managed gas systems in any European city.
These leakage reductions have been brought about through implementation of a costly mains replacement programme which will continue for many years to come.
Other measures such as reduced operating pressure and improved pipe joint repairs have also contributed to the significant reductions in leakage.
The small volumes of natural gas leakage in conjunction with the wide area over which the old network was constructed, are such that the leakage has insignificant effect on air quality.
On the other hand the expansion of the natural gas grid and the increased use of natural gas for heating has resulted in significant improvements in air quality through the substantial reductions in carbon dioxide, nitrous oxide and sulphur dioxide emissions.
Natural gas (methane) is a naturally occurring substance e.g. marsh gas. It is non-toxic and being lighter than air is dispersed quickly into the earth's atmosphere.
No concerns have been expressed to me in recent times.
