Mr. Gavin Lawlor:

To help with regard to wind farms and flexibility, there was a tradition of putting in a maximum hub height and blade range. The difficulty came in terms of environmental impact assessments and how we properly assess a range. The impact assessment has been developed so we can do this. Exactly as Mr. Jones has said, if people go outside of the range by 2 mm or 2 m we have what we call the "so what" test. We ask what are the environmental effects and this is what materially determines it. This is back to why section 5, and now section 8, is so critical. It is a key difference between the new system and the old system. In the old system we could not ask whether a development was compliant. It now appears this question can be asked but only by developers.
