Mr. Ciarán Ó hÓbáin:

I will ask Mr. Mulligan, the programme director, to take the first two questions, and Mr. Neary, the chief technical officer, to deal with the third which concerns a technical point.

In dealing with the cost the Minister was very clear in his presentations to both the committee and the Dáil that the cost we were seeing was the maximum that could be envisage. The committee will see this coming through in the answers to questions. It is a capped cost, from which one will have to work back to assess what the actual cost could and is likely to be. We have very clear views in that regard.

I ask Mr. Mulligan to pick up on the first two questions.
