1 For our environment FAIRMODE Technical Meeting 26-28th June 2018, Tallinn Source oriented source apportioment of air pollutants German experience Stephan Nordmann Unit II 4.1 General aspects of air pollution control

2 Statutory regulations Air quality directive 2008/50/EC and implementing Decision 2011/850/EU: - Air quality plan when limit value of air pollutant is exceeded (2008/50/EC Article 23) - Content of the air quality plan is specified in implementing decision 2011/850/EU (Article 13 and Annex 2 H-K) and more details in IPR guidance - According to Annex 2 I source apportionment has to be performed

3 Statutory regulations 2011/850/EU Annex 2 I Requirements in Source Apportionment Regional Background Urban Background Local increment

4 Air quality plans in Germany UBA project 2014 Document on the effectiveness of measures in air pollution control ( /bestandsaufnahme-wirksamkeit-von-massnahmen-der)

5 Air quality plans in Germany NO2 Increments NO2 Sources

6 Air quality plans in Germany PM10 Increments PM10 Sources

7 Example air quality plan of Berlin Different source oriented methods of source apportionment for the regional background, urban background and local increment erlin.de/umwelt/luftqualitaet/de /luftreinhalteplan/download/lu ftreinhalteplan_berlin_2011_k orrigiert.pdf

8 Example air quality plan of Berlin Final Regional Source scale contribution (transboundary for NO2 contribution) Chemical transport model REM-Calgrid (RCG) Urban scale (contribution of different emission sectors) Gaussian model (IMMIS-net) - simulation for each sector individually Local scale (contribution of different emission sectors) Screening Modell (IMMIS-Luft), Canyon-Plume-Box Modell (IMMIS-CPB) erlin.de/umwelt/luftqualitaet/de /luftreinhalteplan/download/lu ftreinhalteplan_berlin_2011_k orrigiert.pdf

9 Air quality plans in Germany Collection of all plans in Germany: (158 entries) What are the source oriented methods behind the source apportionment and how is the quality assurance performed?

10 Examples for source oriented models in other air quality plans City Title of plan Jahr Model for regional Model for urban background Model for local scale Berlin Luftreinhalteplan 2011 bis 2017 für Berlin 2017 RCG - CTM Immis net - Gaussian Immis luft - Screening Nürnberg 2. Fortschreibung LRP 2017 Austal - Dispersion for Point sources (Lagrange) Miskam - CFD Rostock Luftreinhalte- und Aktionsplan für die Hansestadt Rostock 2015 RCG - CTM Prokas - Gaussian, Austal - Lagrange, MISKAM - CFD Oldenburg Luftreinhalteplan für die Stadt Oldenburg 2012 Immis net - Gaussian Immis luft - Screening Duisburg Luftreinhalteplan Ruhrgebiet EURAD - CTM Immis net - Gaussian Immis luft - Screening

11 Conclusion Current air quality plans mainly focus on NO2 Responsibility regional and local authorities Many different source oriented approaches are applied in air quality planning in Germany modelling is often done by private consultants Models for different increments are often based on national VDI guidelines (e. g. Gaussion model VDI 3782 Blatt 1 (1992), Quality assurance local scale models VDI 3783 Blatt 9 (2005), CFD - MISKAM 3782 Blatt 8 (2010), )

12 UBA project Transboundary air pollution Goal: Quantification sources contributions for high PM10 concentrations in cold episodes in the Eastern part of Germany Duration: 2.5 years (end March 2019) Contractor: TNO, TROPOS, FUB Working packages: Optimization of meteorological simulation focus PBL simulation (FUB) CTM modelling with the CTM LOTOS-EUROS and optimization(tno) Source oriented source apportionment with tagging approach with Labels on sectors and regions (TNO) Receptor oriented source apportionment with PMF based on measured PM composition (TROPOS) Comparison source contributions from source and receptor oriented approaches
