I would not be able to comment or speculate. However, the requirements are not limited to pp approval as in change of use, (I would suspect that would have nothing to do with the IAA but is a condition of the local planning authority)
Helicopter performance , light requirements, navaid facility, crash plan, comm's, and of course pilot's experiance level. I believe the IAA have a standard format, but will only authorize on a case by case basis. That discretion is clearly stated. Check Annex 14 ICAO and SI 72...
