— prescribed perimeter set out in the prescribing order of n°#x27; a PPR (natural or technological);
— perimeter d' exposure to risks that corresponds to the perimeter regulated by the approved PPR. This approved perimeter is a public utility easement (PM1 for PPRNs and PM3 for PPRTs);
— perimeter d' study corresponding to #x27; envelope in which hazards have been studied.
