E: Run SimpleTreat 4.0, use substance properties compiled in your chemicals inventory. In addition expert judgement is necessary to consider process-integrated risk management measures. With SimpleTreat 4.0 the generic distribution of the substance to the compartments water, soil / sewage sludge and air is determined after the substance has been emitted from the industrial process. It is not about the numerical results, but about determining whether the substance can be released from the sewage …

E: It is important to establish meaningful chemicals inventories (plant-specific, sector-specific or BREF-specific). Block 1 will guide you through the steps necessary to establish this inventory. It also guides you to identify substances used, collect all data necessary to assess if the substance is a (relevant) target substances, and if the substance used is already subject of regulation.

E: A suggestion of what information should be compiled can be found in the proposal for the chemicals inventory. Information necessary for the safe use of a substances, like substance properties, recommendations for elimination, BATs can only be identified for individual substances. For this reason, it is not sufficient to know the products / mixtures used. A single substance is identified with: Substance name, unique identifier (CAS-no. and/or EC-no., IUPAC name)

E: A suggestion of what information should be compiled can be found in the proposal for the chemicals inventory. The information on substance properties is collected independently of the review of the regulatory status. The assessments to be carried out in Block 1 and 2 are: release to waste water, degradability, mobility, PEC / PNEC ratio, PBT assessment

E: Regulatory status means whether the substance is subject to certain use restrictions in national or European legislation and / or if regulation is expected. E.g. the substance might be regulated under the REACH Regulation (certain uses restricted, use is subject for authorisation, substance is on candidate list etc.), or identified as priority substance under Water Framework Directive (WFD), BATs derived under IED

E: Be aware, that chemicals which are eliminated by other measures e.g. from air by a scrubber-system also may enter the waste water stream. Industrial use of chemicals means release of chemicals into the environment not only via wastewater. Other pathways might be more relevant than emissions via wastewater (e.g. emissions to air or through widespread use of manufactured articles). Some chemicals may be recycled and reused internally, or they may not be released to the environment via other pat…

E: Besides the mechanical cleaning, the biological treatment stage is an essential part in treating waste water. Many substances can be degraded by microbial activity and this may be enhanced in WWT by adaptation. Biodegradability is a key parameter in finding target substances. The more a substance is persistent, the higher is the possibility that the substance could be released from a WWTP and persist in the environment. Biodegradation is a complex process and may not be described by a single …

At this point the environmental PEC/PNEC ratio is not addressed. The environmental risk assessment is a step later at the end. To ensure the proper performance within the WWTP, the protection of WWTP’s microorganism flora is in focus here. E: Take into account that the substance might be used in different products / mixtures or processes. Worst case is that PEC / PNEC > 1.

E: The substance is regarded as absorbtiv (the substance is not mobile) if the following parameter are met. In this case the decision is to be answered with yes: • Adsorptivity log K oc ≤ 4 (L/kg or dimensionless), test guideline OECD 106 or OECD 121 (HPLC-method) or calculation from log K ow . The organic carbon / water partition coefficient may only be measured or calculated for non-ionisable organic chemicals.

E: If a substance can be accumulated in the body, this is called bioaccumulation. Although this process does not take place in the sewage treatment plant, bioaccumulation is per se a hazard indicator from the PBT concept, so that it should in principle be avoided that bioaccumulating substances are released into the environment.

Because the substance is found in effluent water, too, the risk assessment has to be conducted similarly to mobile substances. Make sure that the amount of substance does not lead to PEC / PNEC > 1; Take into account that the substance might be used

E: End-of-pipe measures contribute to the elimination of substances from wastewater. Whether the the end-of-pipe-measures applied at the WWTP you release to are suitable for the eleminiation of a not readily biodegradable and at the same time mobile substance is examined at this point of the interactive scheme. From the multitude of possible processes in a WWTP the following measures are listed as examples. In the analyses it is irrelevant whether it is your own WWTP or a third-party facility.

E: This group of substances has properties that give rise to concern besides the criteria for identification as “hazardous” e. g. according to CLP and should be used with caution. Once released to the environment they can pose a risk to the environment or human health even without having any yet identified adverse effects on the environment or on human health via the environment.

E: Relevant target substances have a potential to be released (could not be eliminated by WWTP) and have (eco)toxicological substance properties of concern. Step 1: The aim of step 1 is to check if the substance has a potential to be released via WWTP into the environment by assessing the persistence and the mobility and taking into account expert judgement on the effect of end-of-pipe-measures on release minimisation. The result is the identification of target substances. Target substances do …
