Restricted area of the Preventive Natural Risk Prevention Plan of the municipality of Gémenos — Bouches-du-Rhône — 13DDTM2016160163 (RETRAIT swelling OF ARGILES)

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.针对天然潜在污染风险（PPRs），《环境法典》第L562-1条将相关管控区域划分为两类：风险直接暴露区，以及虽未直接面临风险但需采取预防措施以避免风险加剧的区域。依据危险等级的不同，每类区域均需遵守可强制执行的管控规范。法规通常将区域细分为以下三类： 1. 禁止建设区（又称"红色区域"）：该区域危险等级较高，通用规则为禁止任何建设行为； 2. 管控建设区（又称"蓝色区域"）：该区域危险等级中等，建设项目需遵循适配问题类型的相关要求； 3. 非直接风险暴露区：该区域虽未直接面临风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业经营场所等行为可能加剧既有风险或引发新风险，因此需遵守相关禁令或要求（参见《环境法典》第L562-1条）。该类区域仅适用于天然潜在污染风险（RPPs）。
