In article 5 section 9 of the Aarhus Convention the gradual creation of an interrelated nationwide system of directories and registers for the record of the environmental pollution in a publicly accessible database is agreed. The basis for the European and German regulations is the PRTR report. Such a register on pollutant emissions is aiming at keeping the public informed on the release and transfer of the most important pollutants into or to the air, ground, and waters. With the ratification of the PRTR report, and with its entry into force, Germany, and the European Union are obliged to create a national or Europe-wide register on pollutant emissions, and on the transfer of such. At EU level the European Pollutant Release and Transfer Register (E-PRTR) was established based on the PRTR-VO (act (EG) Nr. 166/2006). The reporting and publishing of the data in Germany is regulated by the PRTR act (SchadRegProtAG). Both PRTR acts have primarily in common to regulate the record of emissions emanated by so-called point sources. Nationwide, diffuse sources were not registers yet; they were registered in the European PRTR for a few selected pollutants.
The project is aiming at acquiring, validating and providing the necessary data for the German PRTR in the field of diffuse sources. Therefor, a procedure for the determination of a data model for the outline of diffuse sources in Germany shall be developed for the PRTR in order to be able to provide appropriate, and comprehensible emission data to the broad public. Available data on environmental pollution from diffuse sources are validated and processed for the purpose of publication in the PRTR register. The processed data on emissions from diffuse sources shall be integrated into the PRTR system and shall be made available to the public. The objective is to present as regionalized as possible, beside information on industrial emissions, also relevant data on emissions from traffic, farming and the private households.
Thereby, the project supports the implementation of a register in the field of diffuse sources in Germany on pollutant emissions and on the transfer of such, and contributes sustainably to the qualitative enhancement of the data base.
