Senator Ulick Burke wants the Minister for the Environment and Local Government to come before the House to discuss Tynagh mines. I am aware of the position regarding the disused mines there, but the Senator wants to know who is in charge of them, who is responsible for the contamination and who will decontaminate them. The latter term is employed when mines are to be fully decommissioned. I will try to find out which Minister would be the appropriate one to deal with this question.
