Ordinance on Facilities Handling Substances that are Hazardous to Water(AwSV, Verordnung über Anlagen zum Umgang mit wassergefährdenden Stoffen) is a new regulation published in April 2017 and coming into force on 1 Aug 2017 in Germany. It replaces the General Administrative Regulation under the Federal Water Act on the Classification of Substances Hazardous to Water in Water Hazard Classes (VwVwS). Its purpose is to protect bodies of water from detrimental changes to their characteristics caused by substances that are hazardous to water emanating from facilities handling these substances.
AwSV sets the rules to determine water hazard class (WGK) for a substance and mixture using CLP Regulation (EC) No 1272/2008 on the classification, labelling and packaging of substances and mixtures as assessment basis. It also introduces a new category of substances: “Generally hazardous to water” (with no WGK assigned) for certain substances and mixtures, e.g., floating liquids. For the mixtures assessments, the M factor of a substance classified as toxic to the aquatic environment will need to be taken into account.
This ordinance shall not apply to:
German's Federal Water Act requires that facilities handling substances and mixtures that are hazardous to waters must be built and operated in a way that water bodies are protected from pollutions. To this end, the Water Hazard Class (WGK) of a substance or mixture has to be determined, communicated and documented. The annex I of AwSV provides guidance on WGK classification
There are three water hazard classes (WGK).
Furthermore, substances can be classified as non-hazardous to water (nwg) or are deemed hazardous to water in general (awg).
The following substances and mixtures are deemed to be hazardous to water in general and are not classified into water hazard classes:
Substances that are currently not published with a WGK classification in the Bundesanzeiger or on UBA's website are regarded as not classified and must be regarded as highly hazardous to water (WGK 3) for reasons of precaution. Facility operators are obliged to self-classify these substances according to Annex 1 of AwSV and to submit the WGK documentation to the Umweltbundesamt (UBA).
All mixtures have to be self-classified. WGK classifications of mixtures are not submitted to the Umweltbundesamt. These classifications have to be documented according to Appendix 2 Number 2 or 3 of the AwSV and have to be made available to the local authorities on request.
