Basic advice on general questions about the AwSV

The AwSV as the central regulation for facilities for handling substances hazardous to water confronts facility operators with a multitude of requirements and questions that must be solved and implemented in daily facility operation.

This begins with the formal requirements for AwSV facilities and leads to the technical requirements, which are often associated with room for interpretation. Interactions with other areas of law (e.g. building law, fire protection, immission control law) also play an important role here. A first important step is often the delimitation of installations according to § 14 AwSV.

The experts according to § 53 AwSV of BfU Dr. Poppe AG support with their expertise in any questions regarding the implementation of the individual requirements of the AwSV. Please do not hesitate to contact us!

Notification of installations for handling substances hazardous to water in accordance with § 40 AwSV

If you want to build or substantially change a facility that is subject to inspection pursuant to § 46 i.V.m. Annexes 5 and 6 AwSV, you must notify the competent (lower) water authority in writing at least six weeks in advance.

The notification must contain the following information on:

• the operator
• the location and boundaries of the installation
• the substances hazardous to water that will be used in the installation
• certificates of usability issued by building authorities
• technical and organisational measures relevant to the safety of the installation

In addition, it is often useful to provide a detailed description of the installation and, in particular, to assess the implementation of the requirements for the retention of substances hazardous to water leaking in the event of a leak (§ 18 AwSV) as well as the requirements for the retention of extinguishing water contaminated in the event of a fire (§ 20 AwSV).

The experts according to § 35 AwSV of BfU Dr. Poppe AG will be pleased to support you in compiling or preparing the documents for a notification according to § 40 AwSV.

Suitability determination according to § 63 WHG

Pursuant to Section 63 of the Federal Water Act (WHG) in conjunction with Section 42 of the Ordinance on Installations for the Handling of Substances Hazardous to Water (AwSV), a suitability assessment is required if you operate installations with a hazard level B or higher pursuant to Section 39 AwSV in which substances hazardous to water are stored, filled or handled (LAU installations). The purpose of the suitability determination is to have the water-legislative suitability of the facility as a whole and of the individual parts of the facility determined by the authorities and to operate the facility so safely that possible water pollution is not a concern. It is important to note that the concrete requirements for the design of a suitability determination may vary depending on the federal state. Close coordination with the competent authority is generally recommended in these cases.

The experts according to § 35 AwSV of BfU Dr. Poppe AG will be pleased to support you in the preparation/compilation of the documents for a suitability determination according to § 63 WHG.

Preparation of expert reports / expert opinions pursuant to § 42 AwSV

Within the scope of the application for a suitability determination pursuant to Article 63 WHG, an expert pursuant to Article 53 AwSV must assess in a second step by means of an expert opinion/technical statement whether the design of the respective facility for handling substances hazardous to water as presented by means of the application for a suitability determination fulfils the requirements under water law pursuant to WHG, AwSV and subordinate legislation (e.g. Technical Rules for Substances Hazardous to Water (TRwS)).

An expert opinion is also required if the operator of the facility waives the requirement for a suitability determination pursuant to Article 41(2). In this case, the expert must assess and confirm that the respective installation meets the requirements of water legislation as a whole.

The experts according to § 53 AwSV of BfU Dr. Poppe AG will be pleased to support you in the preparation of expert reports/technical opinions according to § 42 AwSV.

Creation of concepts for extinguishing water retention

According to § 20 AwSV, facilities must be planned, constructed and operated in such a way that substances hazardous to water, extinguishing, sprinkling and cooling water as well as the resulting combustion products with properties hazardous to water are retained in accordance with the generally recognised rules of technology.

Section 20 AwSV stipulates the need to retain extinguishing water as a legal basis, but without formulating specific requirements. In the absence of generally recognized technical rules for retaining extinguishing water, the LöRüRL was nevertheless used to determine the need for retaining extinguishing water based on its assessment principles. As of January 1, 2020, the LöRüRL was repealed by the German Institute for Structural Engineering (DIBt).

The reason for this was that it no longer corresponded to the current state of the art and therefore could no longer be viewed as a generally accepted rule of technology. As a result, the LöRüRL is no longer applied uniformly in all federal states. While some rely on their state-specific extinguishing water retention guidelines, other federal states have decided against applying them. The planned amendment to the AwSV is intended to create generally applicable, concrete regulations for the retention of extinguishing water in order to close the existing regulatory gap. The associated 1st Amendment Ordinance to the AwSV was originally scheduled to come into force in autumn 2021. The legislature has not yet implemented its proposed change.

Support for legally compliant planning

The legally compliant planning of facilities for handling substances hazardous to water includes compliance with the legal regulations and requirements in order to prevent water pollution caused by the handling of substances hazardous to water. Here are some important steps and aspects to be considered in legally compliant planning:

• Site and plant selection
• Determining the classification of the facility according to § 39 AwSV
• Technical measures (e.g. according to § 18 AwSV)
• Plant documentation according to § 43 AwSV
• Compliance with reporting/notification obligations

In many cases, it is advisable to have the plans evaluated by an expert in accordance with § 53 AwSV in order to communicate and coordinate the plant planning with the competent authorities.

The experts according to § 53 AwSV of BfU Dr. Poppe AG will be pleased to support you in the legally compliant planning of AwSV plants.

Construction supervision

Facilities for handling substances hazardous to water must be planned and constructed professionally in accordance with the AwSV. It is advisable to have a competent person accompany the facility during the construction phase. The competent person monitors the construction or modification of the facility and ensures that the requirements of the AwSV are met in order to avoid water pollution. The aim of construction supervision is to ensure that the facility is constructed or modified properly and in compliance with environmental protection regulations. This ensures that potential risks to water bodies from the handling of substances hazardous to water are minimised.

The experts according to § 53 AwSV of BfU Dr. Poppe AG are happy to support you in the supervision of the construction of AwSV facilities.

Communication with authorities

In the context of the construction, substantial modification and operation of facilities for handling substances hazardous to water, close cooperation and coordination with the responsible water authorities is often expedient. Through targeted communication, a plant operator can avoid unpleasant problems (e.g. time delays or even complete changes with regard to possibly already advanced plant planning).

The experts according to § 53 AwSV of BfU Dr. Poppe AG will be happy to support you in communicating with the authorities on questions of plant construction, modification or operation.

Supervision of specialised companies

Pursuant to Section 62 (1) AwSV, establishments that carry out the activities specified in Section 45 (1) AwSV on the installations and parts of installations specified therein must be certified as a specialised firm by an expert organisation or a quality and monitoring association. Certification may be limited to certain activities. It shall be limited to a period of two years.

As a recognised expert organisation according to AwSV, BfU Dr. Poppe AG offers specialist companies our support in obtaining or maintaining specialist company status according to § 62 AwSV.

This includes, among other things, the implementation of training (WHG basic course) and advanced training for specialised companies. Depending on requirements, the necessary training for the WHG basic course is also carried out in-house or corresponding monitoring activities are completed.

Support in plant documentation in accordance with § 43 AwSV

With the introduction of the AwSV in 2017, operators of installations for handling substances hazardous to water were obliged to keep installation documentation for each installation. Pursuant to § 43 AwSV, the plant documentation must include the following contents:

• Information on the structure and delimitation of the installation,
• information on the substances used,
• information on the design and materials of the individual plant components,
• information on safety equipment and protective measures,
• information on the retention of extinguishing water,
• information on the stability of the installation.

In addition, mandatory documents such as the operating instructions pursuant to § 44 can be a useful part of the installation document.

The experts according to § 53 AwSV of BfU Dr. Poppe AG will be pleased to support you in the preparation/compilation of an installation documentation according to § 43 AwSV.

Support for the compilation of an AwSV facility register

Operators of facilities for handling substances hazardous to water are often faced with the problem of a lack of an overview of all facilities for handling substances hazardous to water operated at the respective plant when compiling a facility documentation pursuant to § 43 AwSV. Especially in cases where a large number of such facilities are operated at the site, it is advisable to create a good overview of all facilities. An AwSV facility register is useful here, which gives the facility operator an overview of all important parameters of the AwSV facilities and can serve as an overview for the individual facility documentation.

The experts according to § 53 AwSV of BfU Dr. Poppe AG will be happy to support you in identifying and recording all AwSV facilities operated at your sites and in creating a facility-specific AwSV register.
