I thank Dr. Cotter. Can we tease out the issue of the derogation? Am I right in saying there is a correlation between the quality of water in the south and east of the country and the granting of derogations in those regions of the country? Various maps seem to show a correlation. Can the EPA state whether there is a correlation or has that analysis been done?
