DDT 91 — Technological Risk Prevention Plan (PPRT) of HERAKLES — ISOCHEM: polygon-type issues

The PPRT d'HERAKLES — ISOCHEM was approved on 19 September 2014. In general, the stakes are people, property, activities, elements of cultural or environmental heritage, threatened by hazards and likely to be affected or damaged by it. A PPR issue can therefore be taken into account (or not) depending on the type or types of hazard treated. These elements form the basis of knowledge of the soil required for the Â#x27; development of the PPR, in the zone d’#x27; study or near it, at the date of #x27; analysis of the issues. The data of #x27; Issues represent a photograph (fixed and not exhaustive) of assets and people exposed to hazards at the time of #x27; development of the risk prevention plan. This data is not updated after PPR approval. In practice they are no longer used: the stakes are recalculated as needed with up-to-date data sources. __Origin__ RISK/N_RISQUE_TECHNOLOGICAL __Partner organisations__ DDT Essonne __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-addb18c6-a33f-426e-a543-8bd6fef4ceaa) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/1ecbbc3644ea63c4f64e464d3151806c188cca52)
