Dataset Direct Download Service (WFS): Restricted zone of the PPRT of the establishment BUTAGAZ in the commune of Douhet in Charente-Maritime

For PPRTs, the environmental code defines a single category of zones for zones (L515-15 et seq.): areas at risk. Unlike natural RPPs, PPRTs never have restricted areas that are not directly exposed to risk.
Depending on the hazard level, each TRPP area is subject to an enforceable settlement. The PPRT regulations generally distinguish two types of zones:
1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction;
2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue.
The instructions in the PPRT development guide add a gradation within the “red zones” and “blue zones”.

针对管道破裂风险预防计划（PPRT），《环境法典》为相关区域（L515-15条及后续条款）划定了单一类别的区域：风险区域。与天然RPPs不同，PPRT从不设置未直接暴露于风险中的限制区域。
根据危险等级，每个TRPP区域均需遵循可强制执行的管控要求。PPRT相关法规通常将区域划分为两类：
1. 禁止建设区域，又称"红色区域"：此类区域危险等级较高，基本原则为禁止建设活动；
2. 指定区域，又称"蓝色区域"：此类区域危险等级中等，相关项目需遵循适配问题类型的管控要求。
PPRT编制指南中的指引还在"红色区域"与"蓝色区域"内部增设了分级机制。
