I wouldn't worry too much about the NOTAM. If the airport was going to reopen before then, it would be easy to issue a new NOTAM superseding that information.
Don't forget that the local elections are in May and the candidates are already out canvassing. This is the ideal time to be pushing for the airport's re-opening - any aviators living in Galway City and County should take this opportunity to lobby the candidates. Now is the time to get their attention - they won't give a Highlander's Damn after they get elected!
Also you have to remember that the Councils are run by incompetents who can't make a decent job of the areas that they are supposed to be qualified to deal with - i.e. normal municipal matters - never mind airports and aviation, which is outside their experience. (Despite the 1994 Local Government Act giving them a "General Competence" to basically get involved in anything. They love quoting this to justify Arts Centres etc and forays into areas where they really have no business.). But no doubt they will engage Consultants at great cost to tell them what they should do and then they will do what they wanted to do all along anyway.
