4. Previous Phare projects EL Phare Air Accession Twinning Project ES98/ IB-EN- 018a, Air Quality management: issues for EU accession EL Phare Air Accession Project ES 9805.02, Supply of Air Monitoring Equipment (Investment) Development of Estonian Air Quality Management System was one of the main recommendation made by the Twinning project.

5. What is Air Quality Management? An endless loop of o Ambient Air Quality Monitoring Data o Emission Databases o Air Quality Modelling Training Evaluation

6. Principle of the system Dispersion modelling Emissions Meteorological data Air quality monitoring Calculated levels Checking emissions Based on meteorology and emission inventories the levels of air pollutants are calculated using dispersion modelling. Calculated levels are compared with measured values. If calculated and measured values are different the emission sources are checked by measurements.

8. The Goal of the Project: To Provide Estonia with a Modern Nationwide Air Quality Management System

9. Progress of the project As the tender was technically very complicated the preparation and approvement of final Tender Dossier took 17 months (November 2002 – April 2004) The first draft version of Tender Dossier was sent to Ministry of Finance (MoF) in 14th of November 2002. Analysis of the Tender Dossier was made by the Expert The deadline for submission of offers for the supply component was on the 28th of June 2004 and there were two tenders. The evaluation of tenders took place in two periods totally from 28th of June until 30 November of 2004 The contract was signed with SMHI on 16 of February 2005 Duration of the project- one year, budget 3,5 MEUR

10. Main obligations of the Estonian AQMS according the Project National obligations – reporting to the EU and international organizations Maintaining and ensuring good air quality by planning activities and assessments Dissemination of the information to public regarding the air quality in Estonia

14. AirViro One corner stone is that only ONE software application installation is needed (in the Central Office). Users at the Central Offices access via the Local Area Network (LAN). County Offices access via the Internet utilising a standard PC with Office Package and an Internet connection. No additional application/software installations are needed at the County Offices.

15. Project supply Workstations – air quality experts at EI and CEDs were equipped with workstations and laptops to use the system Two identical IBM server systems – in EERC and EIC, mirrored with each other Server system, workstations and IAirViro software with extensive training and development (creation of emission databases, meteorological databases etc)

16. Air Quality Modelling Wind model Langrangean / Gaussian model Grid model MATCH model Heavy gas model Street canyon model Receptor model

17. Emission Database Organizes emission information Provides reporting functions for local and EU use Provides simulation functions Input to dispersion modelling

18. Upgrading the monitoring stations Existing monitoring stations were upgraded. Analyzers were replaced and new components added Meteorological masts added to background stations Displaceable monitoring stations for modelling purposes were equipped

19. Air Quality Monitoring Equipment Three new monitoring stations will measure SO 2 NO X O 3 PM 10 / 2.5 TSP BTX

20. Estonian AQ monitoring network Urban stations Background stations

21. Meteorological Equipment Three 24 meter masts will provide input to large scale modelling – Ultrasonic Anemometers (x, y, z) wind components – Differential temperature – Temperature – Humidity – Precipitation

22. Contract with EMT was signed to use existing GSM masts for the meteorological sensors and their infrastructure for data collection.

23. Advanced meteorological masts Air quality modelling is based on meteorological parameters. For the system currently four masts are used. Meteorological mast in Tallinn operates since 1994

24. Passive Samplers The pollutant is transported to the sorbent by molecular diffusion Sampling time 1 – 4 weeks SO 2, NO 2, VOC 145 samplers per campaign; 3 campaigns nationwide

25. Passive Samplers Campaigns The measurement campaigns show very low SO 2 and NO 2 values for background sites. Some city locations have rather high levels of NO 2 and VOC.

26. Laboratory Equipment Chromato-mass detector for organic pollution determination High performance liquid chromatograph (HPLC) and UV detector (ketones + aldehydes) Heavy metal detection equipment ICP (air + precipitation)

27. International Reporting Functions for regular reporting to EU

28. Optimized use of a modern Air Quality Monitoring System Problems ? Many organizations involved ? Re-organisations occur ? Staff competence and training ? Service & Maintenance of computers, monitoring equipment, etc ? System Manager function ? Daily operations ? Use of reports and results ? Maintenance of Emission Database ? Daily checks

33. Obligations of the EERC Checking emission data by comparison of the modelling results with national monitoring Assessment of the background concentrations and dissemination of the digital concentration maps Maintenance and development of the AQMS Assisting inspection authorities to solve causes of the specific pollution episodes (monitoring + modelling) Forecast pollution distribution and dispersion during big accidents (precalculated and assessed scenarios for big pollution sources and industries) Development of the air quality action plans with county environmental departments and local authorities

34. Other obligations Development and maintenance of the county air emission databases Checking existing pollution level prior issuing new air pollution permits Checking and comparison of the existing pollution permits with the national emission database Introducing traffic counting data to the emission database Inserting meteorological data from other institutions to the air quality management system

35. Problematic pollutants in Estonia Exceedencies of PM 10 limit values in Tallinn and in other cities; In background stations ozone concentrations tend to exceed even new target values during spring and summer months; In Kohtla-Järve area (oil-shale industry) high levels of specific pollutants are of great concern – hydrogen sulphide, phenols and formaldehyde.

36. Concentration of H 2 S In September 2004 automatic H 2 S analyzer was installed.

37. Problem in Kohtla-Järve Monitoring station Enterprises

38. H 2 S concentrations in Kohtla-Järvel

39. Biggest threats to the system Quality of the output of the system depends on quality of the input data – main source of the errors is air emission database Most important partner is county environmental department (inserting and checking new emission data), without adequate emission data activities of the other partners is irrelevant Long-term financing of the maintenance of the system and accompanying obligations, enacting exact obligations of the parties

40. Conclusions and lessons learnt The first nationwide edb is developed (3500 point sources, 2900 road links) – New type of sources (house holds, traffic, trains, planes) staff Plans & programs Kohtla- Järve, Muuga harbor Drafting action plans for Tallinn agglomeration and Ida- Virumaa zone inform public about air quality and pollution episodes (http://mail.klab.ee/seire/airviro)http://mail.klab.ee/seire/airviro
