An example of this is a mobile refuelling unit for use on construction sites.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What are substances hazardous to water?&#8221; tab_id=&#8221;wassergefaehrdende-stoffe&#8221;][vc_column_text]Substances hazardous to water are solid, liquid and gaseous substances and mixtures that are capable of causing adverse changes in the quality of water permanently or to a not merely insignificant extent.<\/p>\n<p>Articles, on the other hand, are, according to section 3 sentence 1 no. 5 ChemG, objects that are given a specific shape, surface or design during manufacture that determines their function to a greater extent than the chemical composition. Articles do not fall under the definition of the AwSV and are therefore not substances hazardous to water.<\/p>\n<p>Examples of articles are batteries and fluorescent tubes.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How are installations classified into hazard levels according to AwSV?&#8221; tab_id=&#8221;gefaehrdungsstufen&#8221;][vc_column_text]In \u00a7 39, the AwSV specifies the hazard levels of installations based on the relevant volume or mass and the water hazard class of the substances, which form the basis for staggering the requirements.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How are AwSV installations delimited?&#8221; tab_id=&#8221;abgrenzung-awsv-anlagen&#8221;][vc_column_text]An installation includes all parts of the installation that have a close functional or procedural relationship with each other. This is to be assumed in particular if substances hazardous to water are exchanged between the plant components or if there is a direct safety connection between them.<\/p>\n<p>The delimitation must be made as required by the function of the plant as well as the procedural context. This is to avoid that processes that take place in several steps are taken apart. When delimiting installations consisting of several parts in which substances hazardous to water are contained as intended, the function of the installation should therefore remain in the foreground and interrelated treatment steps should not be assigned to different installations.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What is the difference between storage, temporary storage and staging?&#8221; tab_id=&#8221;unterscheidung-lagern&#8221;][vc_column_text]Storage is the holding of substances hazardous to water for further use, release or disposal. An installation also includes the areas, including their facilities, used for the storage or regular parking or temporary storage of substances hazardous to water in containers or packaging.<\/p>\n<p>Areas on which containers with substances hazardous to water (e.g. IBCs) are temporarily parked or made available in connection with transport are not storage facilities.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Is waste water to be classified as hazardous to water within the meaning of the AwSV?&#8221; tab_id=&#8221;abwasser&#8221;][vc_column_text]Pursuant to section 62(6) no. 1 WHG, the requirements for the handling of substances hazardous to water do not apply to installations for the handling of waste water. Thus, waste water is not a substance hazardous to water in the sense of the AwSV and the WHG.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How are underground installations defined?&#8221; tab_id=&#8221;unterirdische-anlagen&#8221;][vc_column_text]Underground installations are installations where at least one part of the installation is underground. Underground installations are installations that are fully or partially embedded in the ground or that are not fully visible and embedded in components that are in direct contact with the ground.  An example of this is a waste storage container that is completely embedded in the ground or a filling pipe of a container located in the basement that runs partially underground.<\/p>\n<p>Underground systems with liquid or gaseous water-polluting substances must be considered and checked in particular, as any leakage can neither be detected nor contained if the system is not designed or constructed properly. Therefore, such installations must be technically more complex and should only be used if above-ground installations are not an option. In underground pipelines, for example, detachable connections and fittings must be arranged in liquid-impermeable control devices that must be inspected regularly.<\/p>\n<p> These pipelines must:<\/p>\n<ul>\n<li>double-walled,<\/li>\n<li>designed as a suction line,<\/li>\n<li>be provided with a protective pipe or laid in a duct.<\/li>\n<\/ul>\n<p>Depending on the design, leaking substances hazardous to water must either be indicated automatically by a leak detection system or be visible in a liquid-impermeable control device.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What does AwSV require for existing plants?&#8221; tab_id=&#8221;bestandsanlagen&#8221;][vc_column_text]Existing installations within the meaning of the AwSV are installations that were already constructed before the AwSV came into force on 1 August 2017. The AwSV contains a transitional provision for existing installations that have already been constructed on the basis of the WHG and the supplementary Land regulations when this Ordinance enters into force and are subject to a periodic inspection obligation.<\/p>\n<p>Requirements of the AwSV that are merely organisational and administrative regulations, e.g. monitoring filling and emptying, obligations in the event of operational malfunctions, notification obligations or documentation and operating instructions, apply immediately upon entry into force of the Ordinance. I.e. since 01 August 2017.<\/p>\n<p>The same shall apply to all other requirements of the Ordinance, insofar as they correspond to the requirements that already had to be observed under the respective provisions of Land law.<\/p>\n<p>For existing installations that are subject to periodic inspection, experts must determine during the first inspection under the AwSV to what extent requirements of this Ordinance exist for the installation that go beyond the requirements that had to be observed under the respective Land legislation on 31 July 2017.<\/p>\n<p>Insofar as a final and binding permit for an installation exists, this shall be deemed to be a provision of Land law. In these cases, the continued existence of the old installations does not require a transitional regulation.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How is a material change defined and what are the effects of such changes?&#8221; tab_id=&#8221;wesentliche-aenderungen&#8221;][vc_column_text]Substantial changes to an installation are measures that change the structural or safety-related characteristics of the installation.<\/p>\n<p>Anyone wishing to make a significant change to an installation subject to inspection or to take measures at this installation that will lead to a change in the hazard level must notify the competent authority in writing in advance. Examples of this are changes to the operating conditions, the decisive volume or the water hazard class of an installation.<\/p>\n<p>Such changes must be checked by AwSV experts and, in the case of certain installations, may only be carried out by specialist companies.[\/vc_column_text][\/vc_tta_section][\/vc_tta_accordion][\/vc_column][\/vc_row][vc_row][vc_column]<div class=\"grve-element grve-hr grve-space-divider\" style=\"\"><\/div><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;
