Mr. Michael O'Leary:

By 2021, it will be down to approximately 70 and it should fall away after that. While I expect it to be lower than 70 by 2021, the problem is we have not carried out a full detailed assessment in regard to new ones that will be added and what mitigation or investment is needed for them. There will be targeted investment to deal with that and we are working with the EPA on it. However, I do not want to create illusions about the position when the 2018 report is published in 2019. These things take time. Our investment programme works in bundles so we try to progress a number of schemes at the same time. When they start coming to construction, many will come to completion at the same time and we should see a step improvement.
