Regulatory zoning of a PPRN or PPRM plates of servitudes PM1 — Department of Tarn-et-Garonne

Pursuant to Articles L. 562-1 et seq. of the Code de l'Environment, the Natural Risk Prevention Plans (NRPPs) and the Mining Risk Prevention Plans (MRPs) delimit: — areas exposed to risks in which construction, works, fitting-outs and holdings are prohibited or subject to conditions; — areas not directly exposed to risks in which construction, works, fitting-outs and holdings are prohibited or subject to conditions because they are likely to exacerbate the risks or cause new ones. The regulated zoning of PPRN-PPRM thus constitute the generators (as well as the plates confused with generators) of the PM1 easements. This resource describes the plates of PM1 easements __Origin__ The noise levels emitted by a given infrastructure during an average day are evaluated using numerical models producing isophone curves translated into noise zones, according to the; index recommended for all modes of transport at European level, namely the Lden index and l' index Ln.The isophone curves, described by the resource N_BRUIT_ISOPHONE_L thus serve to delimit the external borders and, where appropriate, internal noise zones by range of #x27; indices. __Partner organisations__ DDT Tarn-et-Garonne, COVADIS __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-e57f635a-e7a7-4e52-9bad-226762362fec) * [COVADIS data standard: Table describing Noise Areas of (to be completed)(http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_BRUIT_ZBR_INFRA_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/54bdd2e8cb65586944525780b36abaaa1e9df1c5)
