Scope of the PRIMAGAZ PPRT in Dainville in Pas-de-Calais

This dataset contains the boundaries at the different stages of the development of the PPRT. 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 (PM3 for PPRTs);
— scope of study which corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRT开发各阶段的边界范围。此类边界均由官方法定文书确立，并自指定生效日期起产生法律效力，其具体分类如下：
— 自然类或技术类PPR处置指令中载明的法定适用范围；
— 与经核准的RPP所规制的风险暴露范围相对应的边界，该核准边界属于公用役权（PPRT对应的PM3）；
— 研究范围，即开展危险源调研所覆盖的空间范畴。
