In mid-November, a Twinning mission on the German Odor Ordinance (abbreviated in German as GIRL) and its systematic approach took place. This is the first time European odor experts came to Israel to support the MoEP on odor nuisance.
The agenda of the week consisted of four workshops and one day of site visits. There was a very intensive dialogue on principles, questions and details of the methodology and of how to solve odor complains in both Germany and Israel. This mission gave an introduction to the German Odor Guideline combined with the European EN Standards and showed the differences to the current methodology in Israel.
The following topics were discussed during the workshops:
Relevant Guidelines (VDI Guidelines/ Standards) of the Commission on Air Pollution Prevention (KRdL) inclusive EN Standards concerning the odor topics:
Odor emissions: measurement and characterization
Dispersion and impact of odors: evaluation, measurement, calculation
Odor in indoor air
Development of the German Odor Guideline (GIRL Geruchs - Immissionsschutz Richtlinie) for more than 25 years;
Expected adoption of the GIRL in the update of the ordinance TA Luft 2017, i.e. an upgrade to a higher legal level;
Detailed discussion about the legal situation and methodology in Israel;
Advantages of this Lagrange model system in comparison to “steady – state” Gaussian model systems;
EN Standard EN 16841 – 1 “Determination of odor in ambient air by using field inspection – Part 1 Grid method” and of EN 16841 – 2 “Part 2 Plume method”. For the first time both methods were introduced in Israel by this workshop.;
The permit procedure in Germany for odor emitting facilities;
In the case of odor complaints, the procedure and the requirements of reliable investigations and documentation;
Expected revisions of EN 13725 "Determination of odor concentration by dynamic olfactometry";
Use and advantage of different olfactometers for emission measurements in Europe and Israel.
The day in the field consisted of a visit to a compost plant installation near Haifa, a livestock farm in the Northern district and Israel's only odor lab, the " Newe Ya'ar Research Center" for Plant Sciences, Animal Science, Plant Protection, Soil, Water and Environmental Sciences, Agricultural Engineering, and Postharvest and Food Sciences.
The STEs presented in this short mission most relevant tools to address odor complains in a reliable way by the methods of the European standard Guidelines, the German VDI Guidelines and the German Odor Ordinance. The expectations of the STEs, the Twinning team and the beneficiary country seem to be fulfilled for the workshops were very well attended.
