Mr. Seán Laffey:

No. It would be a once-off cost of €200 million to €300 million to build the capital infrastructure required. Depending on how often we would have to change the filter, operational expenditure could be as high as €100 million per year, in addition to what we are spending.

The Deputy asked whether the money would come from existing or additional budgets. We have not examined that issue. We are seeking to spend in the region of €650 million this year on capital infrastructure, which represents an historical high. We hope to maintain such a level of expenditure. On the supply chain and our own capacity, we find that a sum of approximately €650 million per year is comfortable for us. We do not propose to spend any more than that figure. There is never any difficulty with spending money; it is a matter of getting value from it.
