PPRN Restricted Areas RHONE AVAL — downstream sector

For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk.Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, crafts, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.

针对自然PPR（natural PPRs），《环境法典》第L562-1条将相关区域划分为两类：风险暴露区，以及未直接面临风险但可预先采取措施避免风险加剧的区域。依据风险等级的不同，每类区域均需遵循可强制执行的开发管控规则。该法规体系通常将区域分为以下三类：
1. 禁止建设区（俗称"红色区域"）：此类区域风险等级较高，原则上执行建设禁令；
2. 管控建设区（又称"蓝色区域"）：此类区域风险等级中等，相关项目需适配风险类型落实特定管控要求；
3. 未直接面临风险，但建设、工程、开发项目或农业、林业、手工业、商业、工业相关设施可能加剧既有风险或引发新风险的区域：此类区域需遵守禁止性规定或特定管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然RPP（natural RPPs）。
