collapsible_all=&#8221;true&#8221;][vc_tta_section title=&#8221;To which companies does the Major Accidents Ordinance apply?&#8221; tab_id=&#8221;geltungsbereich57a1-0826&#8243;][vc_column_text]Whether the Major Accidents Ordinance is applicable to a business depends on the quantities of certain hazardous substances that are or may be present in the business. It is immaterial whether the substances are stored in the strict sense or not (e.g. transhipment facilities). The hazardous substances regulated by the Hazardous Incident Ordinance can be found in its annex. Some hazardous substances are mentioned by name, e.g. petrol or hydrogen. Other substances are subject to the Major Accidents Ordinance because they exhibit certain hazard characteristics, such as acute toxicity (e.g. potassium cyanide) or environmental hazards (e.g. zinc oxide). Substances that are not listed by name or by their hazard characteristics are not covered by the Major Accidents Ordinance. This also applies if they are otherwise hazardous, e.g. from an occupational safety point of view. An example would be concentrated sulphuric acid. In addition to the above-mentioned properties, the accident-relevant substances must be present above certain quantity thresholds for the establishment to be subject to the Major Accidents Ordinance. However, if several different accident-relevant substances are present, they must be added together (<a href=\"https:\/\/www.weyer-gruppe.com\/en\/plant-operators-and-investors\/major-accidents-ordinance-seveso-iii-directive\/#additionsregel\">see addition rule<\/a>).[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What is the addition rule?&#8221; tab_id=&#8221;additionsregel57a1-0826&#8243;][vc_column_text]In the case of an establishment in which no individual hazardous substance is present in a quantity equal to or greater than the respective quantity threshold, the addition rule shall be applied to determine whether the establishment is an operational area within the meaning of the Major Accidents Ordinance. Quotients are formed from the individual quantities of hazardous substances and the respective quantity thresholds for the hazard characteristics from the list of substances in Annex I of the Major Accidents Ordinance. The quotients are then added up according to certain rules. This is carried out with the quantity thresholds for both the upper and the lower class. Depending on which quotient sum is greater or less than 1, the establishment is not an operating area within the meaning of the Major Accidents Ordinance, one of the lower or one of the upper class.[\/vc_column_text][\/vc_tta_section][vc_tta_section tab_id=&#8221;klasseneinteilung57a1-0826&#8243;][vc_column_text]The terms &#8220;upper tier&#8221; and &#8220;lower tier&#8221; were introduced by the Seveso III Directive 2012\/18\/EU, whose national implementation in Germany is the Major Accidents Ordinance of 2017. They are nothing more than additionally introduced terms for operating areas for which the basic obligations or additionally the extended obligations (these terms continue to apply) must be fulfilled.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Does the Major Accidents Ordinance also apply to waste and how is waste assigned to the hazard characteristics according to the Major Accidents Ordinance?&#8221; tab_id=&#8221;geltung-fuer-abfaelle57a1-0826&#8243;][vc_column_text]Yes. According to Annex I of the Hazardous Incident Ordinance, it also applies to waste if it has hazardous substance properties that are relevant to an incident. This applies despite the fact that the CLP Regulation does not actually apply to waste. Instead, according to the List of Wastes Ordinance (AVV) in conjunction with the Waste Framework Directive (<a href=\"https:\/\/www.bmuv.de\/gesetz\/richtlinie-2008-98-eg-ueber-abfaelle-und-zur-aufhebung-bestimmter-richtlinien\">Directive 2008\/98\/EC<\/a>), hazard-relevant properties HP 1 to HP 15 are assigned. This is done in a simplified form via the hazard characteristics <a href=\"https:\/\/www.umweltbundesamt.de\/themen\/chemikalien\/einstufung-kennzeichnung-von-chemikalien\/clp-verordnung\">(CLP Regulation<\/a>) of the constituents. However, this procedure is not compatible with the requirements of the CLP Regulation for the classification of (waste) mixtures; in particular, once a hazard characteristic HP&#8230; has been assigned, it is not possible to infer the correct classification according to the CLP Regulation. In order to avoid having to go through the actual procedure for classifying the waste as a mixture according to the CLP Regulation, the Commission for Plant Safety developed the KAS-25 Guidance Document in 2012. This assigned a hazardous substance property to a waste described by the six-digit AVV No. in accordance with the then valid Substances Directive 67\/548\/EEC, on which the then version of the Major Accidents Ordinance was also based. The assignment was based on conservative estimates. However, this guideline is no longer applicable, as in 2017 the Major Accidents Ordinance was changed to the hazardous substance properties of the CLP Regulation. For the transitional period until the KAS-25 is updated, a guideline published by the North Rhine-Westphalian State Office for Nature, Environment and Consumer Protection (<a href=\"https:\/\/www.lanuv.nrw.de\/\">LANUV NRW<\/a>) is available for the allocation of waste to the Major Accidents Ordinance.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Are substances hazardous to water with a water hazard class automatically hazardous to water within the meaning of the Major Accidents Ordinance?&#8221; tab_id=&#8221;wassergefaehrdung57a1-0826&#8243;][vc_column_text]No. Despite the very similar designations, we are dealing with two different terms. Substances are hazardous to water in the sense of the Major Accidents Ordinance if their toxicity to certain aquatic organisms exceeds specified values according to the CLP Regulation (Regulation (EC) No. 1272\/2008). The definition of substances hazardous to water with a water hazard class comes from the Federal Water Act (WHG) and is much broader than that of the Major Accidents Ordinance \/ CLP Ordinance: For example, rapeseed oil methyl ester (raw material for biodiesel) is not hazardous to water because it falls below the aforementioned toxicity values. However, it is hazardous to water (lowest water hazard class WGK 1) because it floats on the water surface. By floating on the water surface, it can harm aquatic organisms, insects and birds, for example by preventing their oxygen uptake or mobility. In summary, any substance hazardous to waters within the meaning of the CLP Regulation or the Major Accidents Ordinance is hazardous to waters within the meaning of the WHG, but not vice versa. <a href=\"https:\/\/www.weyer-gruppe.com\/en\/plant-operators-and-investors\/water-protection-for-installations-in-accordance-with-awsv\/\">Click here for more information on water pollution control (AwSV).<\/a>[\/vc_column_text][\/vc_tta_section][\/vc_tta_accordion][\/vc_column][\/vc_row][vc_row][vc_column]<h3 class=\"grve-element grve-align-left grve-title-no-line grve-h3\" style=\"\"><span>Our Team<\/span><\/h3>[\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;
