Identification of target substances (Work Package 2)

Leader of the work package is German Environmental Agency (UBA).

This work package consists of two groups of activities:

  • Selection of target substances
  • Fate of substances during emission treatment.

The aim of the work package is to develop a systematic approach to identify the hazardous substances relevant for each IED industrial sectors and which should be considered in the review process of the BAT Reference Documents (BREFs). The identification of the relevant substances will be done by utilizing already existing information.

For the time being there is no procedure existing by which the already available knowledge on hazardous substances can be included in BREFs in a systematic way. There is also not knowledge on which substances might be relevant to be reflected in the BREFs. However, the BREFs should include the latest information on hazardous substances and the measures to reduce the releases. This is the gap that HAZBREF will aim to fill by the activities in this WP.

In order to achieve this aim there is a need to analyze the existing information on substances that have been identified as (potentially) hazardous under various regulatory frameworks such as REACH, Water Framework directive (WFD), HELCOM and the Stockholm POPs convention and NGO initiatives. To verify that the substances listed under these frameworks are relevant for industrial sectors there is a need to collect data on use, volumes used and substance properties as well as to assess the fate of substances during the use and treatment of emissions.

Selection of target substances

The activity will identify the hazardous substances relevant for each IED industrial sector and which should be considered in the review process of the BREFs. The identification of the relevant substances will be done by utilizing existing information.

 HAZBREF project has decided to use three strategies to pinpoint the relevant chemicals of concern in each of the selected sectors. First, we will search for relevant chemicals in the ECHA database according to the use categories and technical functions of individual chemicals and chemical groups. The next step is to evaluate the fate and behavior of these chemicals in the industrial installations and wastewater treatment in order to determine their potential to be released to the environment. If, in addition, a substance has intrinsic hazardous properties, such as toxicity to humans or environment, the need of risk reduction measures and abatement techniques at the industrial sites increases.

Additionally, we search information about the uses of hazardous substances from the ECHA database and the Nordic SPIN register. The focus will be on substance lists and data under the REACH regulation, list of priority substances under WFD, EPRTR, EU POP-regulation and HELCOM Baltic Sea Action Plan.

The collected information will include e.g. amounts of chemical used, sector of industry, relevant substance properties and the description of the hazard (concern).

One outcome will be a tool that will list substances relevant for each IED industrial sector identified in the activities which will help both authorities and industrial installations to address the relevant substances in order to have proper measures applied.

Fate of substances during emission treatment

Not all substances in industrial process that goes to waste water are relevant to be included in BREFs. For example substances that degrade in waste water treatment plant (WWTP) are probably no risk for the environment and the Baltic Sea. Therefore, it is important to assess how big fraction of the hazardous substance will finally be released to the environment (i.e. pass the waste water without change or that adsorb on WWTP sludge).
