The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor development in areas exposed to a major risk. The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through building prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The RPP file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPR is identified by a polygon that corresponds to the set of municipalities the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table makes it possible to map existing PPRTs on the department. Each PPRT document existing in the geographical table N_DOCUMENT_PPRT is linked with its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and the order number of the associated PPR procedure in GASPAR): 1. its administrative procedure for drawing up (or revising) managed in the GASPAR application, on the one hand, 2. its set of numeric spatial data as described in the metadata sheet N_PPRT_AAAANNNN (#0001496).风险预防计划（Risk Prevention Plans，以下简称PPR）由1995年2月2日颁布的《加强环境保护法案》确立，是国家开展风险预防工作的核心工具，其目标是对存在重大风险区域的开发活动进行监测。 PPR由省长审批，通常由领土事务省局（Direction Départementale des Territoires，以下简称DDT）牵头实施。此类计划通过对现有或拟建建筑设定建设禁令、提出建设要求（涵盖建设性条款、风险易损性消减工程、农业使用或耕作方式限制等），对土地利用及土地用途进行规制。 此类计划可处于法定编制阶段、提前实施阶段或已获批阶段。 PPR文件包含说明性报告、法定区划规划图及规制文本，此外可附加有助于理解该计划的其他图文资料（如风险隐患、相关问题等）。每份PPR均通过多边形进行标识：当计划处于法定编制状态时，该多边形对应其所覆盖的市镇集合及规制适用范围；当计划处于获批状态时，则对应受限区域的包络范围。 本地理数据表可用于绘制省内现有PPRT的空间分布图。 地理数据表N_DOCUMENT_PPRT中收录的每份PPRT文件，均与其GASPAR代码相关联，该代码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中关联PPR流程的参考年份与序号）： 1. 一方面是其在GASPAR系统中管理的编制（或修订）行政流程； 2. 另一方面是其数值空间数据集集合，详见元数据表N_PPRT_AAAANNNN（编号#0001496）。
