On 1 August 2017, the German Ordinance on Facilities Handling Substances That Are Hazardous to Water (AwSV) came into force, replacing the Administrative Provision on the Classification of Substances hazardous to waters into Water Hazard Classes (VwVwS). AwSV harmonises the rules to determine a substances water hazard class (WGK) using the CLP Regulation (EC) No. 1272/2008, as the assessment is now based on the GHS Hazard Class and Category Code. In addition, the Ordinance introduces a new category of substances – Generally hazardous to water (with no WGK assigned) – for certain substances and mixtures, for example floating liquids. For mixture assessments, the M-factor of a substance classified as toxic to the aquatic environment will be considered. Operators of facilities are still responsible to document their own classification of a substance (self-classification) and to submit it to the authorities, but in the future, the German Environment Agency (Umweltbundesamt, UBA) will decide on the final classification of substances. Substances, groups of substances and mixtures that are already classified based on the VwVwS are considered as classified under the AwSV (Chapter 2).
