PPRT from Stepan Europe to Voreppe approved on 25-09-2013

Risk Prevention Plans (RPPs) are the key government instrument for risk prevention. Their objective is to control development in areas at risk.
The development of a risk prevention plan generates a set of spatial data organised into several data sets. The same PPR may include spatial datasets containing:
• main PPR encompassing perimeters (prescription perimeter, regulated perimeter);
• restricted areas of the plan once approved.

RPP regulations generally distinguish between ‘construction ban areas’, so-called ‘red areas’, where the hazard level is high and where the general rule is the construction ban; ‘areas subject to requirements’, known as ‘blue zones’ where the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions;
• origins of risk, i.e. the real-world entity which, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object that locates the actual entity causing the risk.

The data are informative, only paper documents with the prefecture’s visa are authentic.

风险预防计划（Risk Prevention Plans，RPPs）是政府开展风险防控的核心工具，其目标为管控风险区域内的开发活动。
编制风险预防计划将生成一系列空间数据，并划分为多个数据集。同一RPP可包含以下空间数据集：
• 主RPP覆盖范围（管控边界、规制边界）：此类边界内的区域按RPP规制可进一步分为三类，即灾害风险等级较高、通用规则为禁止建设的“禁止建设区”（又称“红色区域”）；灾害风险等级中等、项目需根据问题类型适配相应管控要求的“合规要求管控区”（又称“蓝色区域”）；以及未直接暴露于风险但仍受禁令或规制约束的区域。
• 计划获批后的受限开发区域；
• 风险源：即通过自身存在构成潜在风险的实体对象。该实体可通过名称、外部对象引用或用于定位实际风险源的地理对象进行表征。
