Senator Dardis is correct. We are moving from BATNEEC to BAT – best available techniques – but that will not result in a major change for Irish industry in terms of the way it operates currently. BAT demands a high general level of protection for the environment as a whole and there can be no question of sacrificing environmental quality, but regard must also be had of what is economically and technically feasible. It is a balance in the language which recognises that there are difficult issues to resolve between the environment and what is economically viable, but BAT states that one must start with the best available technologies in the area. That would be the criteria applied. However, as in the example given by the Senator, one could introduce a state-of-the-art environmental pollution system costing €10 million although we could not expect every farmer to put it in place on their farms.
