Mr. David Flynn:

I disagree, in that water quality is not the only aspect. We also have the agricultural catchment programme, ACP, which my colleagues from agriculture might talk about, and we have modelling from the EPA and from Teagasc. It about using that whole ecosystem of data and information to build a case around what type of measures will work for water quality - which we are legally required to do, whether we do derogation or not - and then whether a case can be built around what a derogation case would look like beyond 2025 should the water quality start improving.

Mr. Massey may wish to go into the ACP.
