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.

针对自然潜在污染风险（PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及虽未直接面临风险，但可通过预先采取防控措施避免风险加剧的区域。

根据危险等级，每类区域均需遵循可强制执行的管控要求。相关法规通常将区域划分为三类：
1. 建筑禁止区（又称红色区域）：该区域危险等级较高，基本原则为禁止建设活动；
2. 规定管控区（又称蓝色区域）：该区域危险等级中等，相关工程建设需符合针对具体风险类型制定的适配性管控要求；
3. 虽未直接面临风险，但任何建设工程、施工项目、开发活动或农场、农业、林业、手工业、商业及工业活动均可能加剧既有风险或引发新风险的区域，此类区域需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然潜在污染风险（RPPs）。
