Saarland PPRN Restricted Area

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 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; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, 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PPRs（natural PPRs），《环境法典（Environmental Code）》通过第L562-1条款界定了两类区域：风险暴露区域，以及未直接暴露于风险但可预先采取管控措施以规避风险加剧的区域。 依据危害等级的不同，每类区域均需遵循可强制执行的管控规定。相关法规通常将区域划分为以下三类： 1. 建筑禁建区，又称“红色区域”：该区域危害等级较高，通用规则为禁止任何建设活动； 2. 指定管控区，又称“蓝色区域”：该区域危害等级为中等，区内项目需遵守适配风险类型的专项管控要求； 3. 未直接暴露于风险，但建设工程、施工项目、开发活动，以及农业、林业、手工业、商业及工业类农场可能加剧既有风险或引发新风险的区域，需遵守禁建或管控要求（参见《环境法典》第L562-1条款）。该类区域仅适用于自然RPPs（natural RPPs）。
