PPRT NCS (Regulated Area)

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 TPP area is subject to enforceable regulation. The PPRT regulations generally distinguish between two types of areas:1- “Building prohibited areas”, known as “red zones”, where the hazard level is high and the general rule is the construction ban;2- “prescribed areas”, so-called “blue zones”, where the hazard level is medium and the projects are subject to requirements adapted to the type of issue. The instructions of the PPRT development guide add a gradation within the “red zones” and “blue zones”.针对技术风险预防规划（PPRT），环境法典为对应区域（L515-15条及后续条款）界定了单一类别：风险区域。与自然风险预防规划（RPPs）不同，PPRT不存在未直接暴露于风险中的限制区域。 根据危险等级，每个TPP区域均需遵守强制性监管要求。 PPRT相关监管条例通常将区域划分为两类： 1. "建筑禁止区域"，亦称"红区"，该区域危险等级较高，核心规则为禁止建设； 2. "指定区域"，即所谓"蓝区"，该区域危险等级为中等，相关项目需遵循适配问题类型的监管要求。 PPRT编制指南的说明内容还在"红区"与"蓝区"内部增设了分级体系。
