Map Viewing Service (WMS) of the dataset: Perimeter of PPRT on the department of Meuse (55)

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.

本数据集收录了技术风险预防计划 (PPRT) 开发各阶段的边界范围。此类边界范围的核心特征为：均由官方法定行为确立，并自指定生效日期起产生法律效力，具体包含以下三类：
— 自然或技术类风险预防计划 (PPR) 指令文书中载明的法定适用范围；
— 经核准的风险预防计划 (RPP) 所规制的风险暴露范围，此类经批准的边界属于公用役地（对应PPRT的PM3）；
— 用于开展危害研究的空间覆盖范围，即开展隐患研判的边界范围。
