§ 1 Scope

(1) This Regulation lays down the minimum requirements for the discharge of waste water into water from the areas of origin specified in the annexes, as well as requirements for the establishment, operation and use of waste water installations. (2) The The general requirements laid down in this Regulation and the emission limit values set out in the Annexes shall be complied with by the manager, unless further requirements are laid down in the water-law authorisation for the discharge of waste water . The other requirements of the Annexes to this Regulation shall be laid down in the case of the granting of a water-law authorisation for discharge of waste water. Requirements are to be included in the water-law approval only for those parameters which are to be expected in the waste water. (3) Further requirements according to other legislation remain unaffected. Unofficial table of contents

§ 2 Definitions

For the purposes of this Regulation:

1.: Sample a one-off sampling from a waste water stream;
2.: mixed sample a sample taken continuously during a given period, or a sample of several samples taken and mixed continuously or discontinuously over a given period of time;
3.: a sample of at least five samples shall be sampled and mixed in a period not exceeding two hours at intervals of not less than two minutes;
4.: production-specific freight value of the freight value (e.g. B. cbm/t, g/t, kg/t), which relates to the production capacity on which the water-based authorisation is based;
5.: the place where the waste water has been treated with other waste water prior to mixing, otherwise it will be taken for the first time;
6.: Mix the merging of wastewater streams of different origins;
7.: Parameters a chemical, physical or biological measurement quantity listed in the Appendix;
8.: Mixing calculation means the calculation of a permissible freight or concentration resulting from the requirements of this Regulation relating to the individual waste water flows.

§ 3 General requirements

(1) Unless otherwise specified in the Annexes, waste water may be discharged into water only if the pollutant cargo is kept as low as possible after examination of the conditions in individual cases.

1.: the use of water-saving processes in washing and cleaning operations,
2.: the indirekt cooling,
3.: the use of low-emission operating and auxiliary substances, as well as
4.: the process-integrated recycling of substances.

Unless otherwise specified in the annexes, compliance with the requirements set out in the first sentence shall be documented by a waste water register, by an operating diary or by any other appropriate means. (2) The requirements of this Regulation shall be allowed to: are not achieved by processes in which environmental pressures are transferred to other environmental media such as air or soil, contrary to state-of-the-art technology. The use of chemicals, emissions of exhaust air and the amount of sludge produced must be kept as low as possible. (3) Requirements defined as concentration values must not be achieved by dilution, contrary to the state of the art (4) If requirements are laid down prior to mixing, mixing for the purpose of joint treatment shall be permitted if, in total, at least the same reduction in pollutant loads per parameter, as in the case of separate compliance with the requirements. (5) Are requirements for the location of the seizage of Waste water is only permitted if these requirements are met. (6) If waste water flows for which different requirements apply are jointly initiated, the relevant relevant To determine the requirement by means of a mixing calculation and to determine it in the water-law authorisation. Paragraphs 4 and 5 shall remain unaffected in the Annexes to be applied to the place where the waste water is seised or before it is mixed. Unofficial table of contents

§ 4 Analysis and measurement procedures

(1) The requirements set out in the Annexes shall relate to the analytical and measurement procedures in accordance with the Appendix. The German unit procedures for water, sewage and sludge testing, DIN, DIN EN, DIN EN ISO standards and technical regulations of the Water Chemical Society, mentioned in the annex and the annexes, are published by Beuth Verlag GmbH, Berlin, and Published by the Water Chemical Society in the Society of German Chemists, Wiley-VCH Verlag, Weinheim (Bergstraße). The above-mentioned procedural rules are laid down in the German Patent Office in Munich in the form of an archive. (2) Other equivalent procedures can be set in the permit. Unofficial table of contents

§ 5 Reference point of requirements

The requirements shall relate to the place where the waste water is discharged into the aquatic environment and, where specified in the Annexes to this Regulation, also to the location of the waste water or the place prior to its mixing. The discharge point is the same as the discharge of the waste water plant, in which the waste water is treated for the last time. Place before the mixing is also the point of introduction into a public sewage system. Unofficial table of contents

§ 6 Compliance with the requirements

(1) If a value established pursuant to this Regulation or established in the water-legal authorisation is not complied with in accordance with the results of a state-monitoring review, it shall nevertheless be deemed to have been complied with if the results of the review are met: This and the four previous governmental reviews in four cases do not exceed the relevant value, and no result exceeds the value by more than 100%. Checks carried out for more than three years shall not be taken into account. (2) The number of checks carried out in accordance with this Regulation shall be subject to compliance with a value established in accordance with this Regulation or set out in the water-law approval procedure. Significant parts of the associated analysis and measurement procedure for the determination of the respective parameter in accordance with the Appendix to § 4 (Analysis and measurement), but at least two significant digits, with the exception of the values for the relevant parameters. Dilution levels, authoritative. The values set out in the Annexes shall take into account the measurement uncertainties of the analysis and sampling procedures. (3) A value for the chemical which is to be observed in accordance with this Regulation or is set in the water-legal authorisation In accordance with paragraph 1, oxygen demand (COD) shall also be considered to be complied with if the four-fold value of the total organically bound carbon (TOC), determined in milligrams per litre, does not exceed this value. (4) If monitoring is carried out, the following shall be considered: Overrun of a Regulation to be complied with under this Regulation or in the water legislation The value for toxicity of fish eggs, Daphnia, algae and light bacteria as set out in points 401 to 404 of the Appendix to § 4 shall nevertheless be deemed to be complied with if the conditions of the rates 2 to 7 are met. , paragraph 1 shall remain unaffected. The overrun referred to in the first sentence must be based on a content of sulphate and chloride above the threshold of action. The organism-specific threshold of action in accordance with the second sentence is 3 grams per litre for fish, 2 grams per litre for Daphnia, 0.7 grams per litre for algae, and 15 grams per litre for light bacteria. In addition, the corrected measured value must not be greater than the value to be observed. The corrected measured value according to sentence 4 results from the difference of the measured value and the correction value. The correction value is determined from the sum of the concentrations of chloride and sulphate in the waste water, expressed in grams per litre, divided by the specific organism-specific threshold. If the calculated correction value does not correspond to a dilution stage of the dilution sequence set in the determination procedure, the next level of dilution shall be used as a correction value. (5) Countries may allow the results to be the State monitoring shall be equivalent to results obtained by the head of the ladder on the basis of a surveillance procedure recognised by the public authorities.
