Scope of the natural risk prevention plan (PPRN) of the municipality of LE MAS-D’Azil

This dataset contains the boundaries according to the stage of development of the PPRN. The characteristic of a perimeter is to be the consequence of an official act and to produce its effects from a specified date. This may include: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集收录了依据PPRN发展阶段划定的各类边界。 管控范围的核心特征为：其源自法定行为，并自指定生效日期起产生相应法律效力。该类管控范围可涵盖以下类型： — 列入PPR（天然或人工）处置指令中的法定管控范围； — 与获批RPP所规制的风险暴露范围相一致的管控范围，该获批管控范围属于公用役地（PPRN对应PM1，PPRT对应PM3）； — 与危险评估所覆盖的研究边界相一致的研究范畴。
