I'm told that the federal government at the present time has very limited powers to regulate airports and so I think that, in the context of examining what sort of regulatory framework could be applied to the issue of noise, it would be a good idea to look more generally at the federal government's regulatory framework or capacity to regulate airports at this time, because we may find areas other than noise that are important examples of limited capacity on the part of the federal government to regulate airports today.
