Simple download service (Atom) of the dataset: Perimeter of the PPRi of the veyre basin (63DDT19980007) approved on 22-12-2008 — Puy-de-Dôme

This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. This is the following: — 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PPRN在各开发阶段的管控边界。此类边界的核心特征为：其均由法定行政行为所创设，且自指定生效日期起产生法律效力。具体涵盖以下三类： —— 自然类或技术类PPR处置指令中载明的法定范围； —— 经核准的RPP所规制的风险暴露范围，该核准边界为公用役地（PPRN对应PM1，PPRT对应PM3）； —— 研究范围，即开展危险源研究所覆盖的空间范围。
