PPRN — Area regulated by Article R111-3 on the commune of ROSIERES-AUX-SALINES (54462)

Pursuant to Article R.111-3 of the Urban Planning Code, these areas define the risk of subsidisation due to the dissolution of salt. Article R.111-3, approved by Prefectural Order of 19/03/1991, is PPR under Article L562-6 of the Environmental Code. 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.依据《城市规划法典》第R.111-3条，此类区域划定了因盐类溶解引发的补贴风险。经1991年3月19日省令批准的第R.111-3条，属于《环境法典》第L562-6条规定的PPR。 针对天然PPR，《环境法典》划定了两类区域（第L562-1条）：直接受风险影响区域，以及虽未直接暴露于风险但可采取措施避免风险加剧的区域。 根据危险等级不同，每类区域均需遵守可强制执行的处置要求。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"），此类区域危险等级较高，基本原则为禁止建设活动； 2. 管制区域（又称"蓝色区域"），此类区域危险等级为中等，相关建设项目需遵守适配问题类型的特定要求； 3. 非直接暴露于风险的区域：在此类区域中，建设工程、开发活动或农业、林业、手工业、商业及工业类经营场所可能加剧既有风险或引发新的风险，需遵守相关禁止性规定或特定要求（参见《环境法典》第L562-1条）。此类第三类区域仅适用于天然RPPs。
