(Main)Proposed limit values for contaminants in biomethane based on health assessment criteria
Proposed limit values for contaminants in biomethane based on health assessment criteria
This document explains an approach for assessment of limit values for contaminants that may be found in biomethane. Limit values are generally required as an adjunct to a biomethane specification (such as parts 1 and 2 of EN 16723, or an equivalent National specification) or as part of a Network Entry Agreement for injection of biomethane into gas networks.
The methodology employed will permit derivation of limit values based solely on consideration of potential for impact on human health and does not consider other impacts, such as integrity and operation of plant and pipelines used to convey biomethane or appliances involved in its combustion or other regulations like CLP regulation. Where consideration of such impacts would result in proposing lower limit values than those based on health impacts, then the lowest limit values should generally be proposed.

Valeurs limites proposées pour les contaminants dans le biométhane selon des critères d'évaluation relatifs à la santé
Le présent Rapport technique décrit une approche pour l'évaluation de valeurs limites pour les contaminants que l'on peut trouver dans le biométhane. Des valeurs limites sont généralement requises en complément d'une spécification de biométhane (comme les Parties 1 et 2 de l'EN 16723 ou spécification nationale équivalente) ou dans le cadre d'un accord d'entrée de réseau pour l'injection de biométhane dans les réseaux de gaz.
La méthodologie employée permettra d'établir des valeurs limites uniquement sur la base de l'examen de l'incidence potentielle sur la santé humaine, sans tenir compte des répercussions possibles sur les autres éléments, tels que l'intégrité et le fonctionnement des installations et canalisations servant à transporter le biométhane ou des appareils impliqués dans sa combustion, ni des autres règlements comme le règlement CLP. Si l'examen de ces répercussions conduit à proposer des valeurs limites inférieures à celles fondées sur l'incidence sur la santé, il convient en règle générale de proposer les valeurs limites les plus basses.
Predlagane mejne vrednosti za onesnaževala v biometanu na podlagi meril zdravstvene presoje
Ta dokument pojasnjuje pristop k ocenjevanju mejnih vrednosti za onesnaževala, ki jih je mogoče odkriti v biometanu. Mejne vrednosti so običajno zahtevane kot dodatek k specifikaciji biometana (npr. dela 1 in 2 standarda EN 16723 ali enakovredna nacionalna specifikacija) ali kot del pogodbe NEA (Network Entry Agreement) za vbrizgavanje biometana v plinska omrežja.
Uporabljena metodologija bo omogočala izpeljavo mejnih vrednosti izključno na podlagi upoštevanja morebitnega vpliva na človeško zdravje in ne upošteva drugih vplivov, kot sta celovitost ter delovanje obrata in cevovodov, ki se uporabljajo za prenos biometana, oziroma naprav, vključenih v njegovo zgorevanje, ali drugih uredb (npr. uredba CLP). Če bi upoštevanje takih vplivov pomenilo predlaganje nižjih mejnih vrednosti od tistih, ki temeljijo na vplivih na zdravje, je treba na splošno predlagati najnižje mejne vrednosti.
