Croatian Air Quality Monitoring Strategy 2002 − onward Sonja Vidič Meteorological and Hydrological Service of Croatia 10000 Zagreb, Grič 3, vidic@cirus.dhz.hr
WHY 2002 ? Regulation on Sitting of National Network Stations for Continuous Air Quality Monitoring (OG No. 4/02) Programme on Air Quality Measurement in the National Air Quality Monitoring Network (OG No. 43/02)
Historical overview • Before 1974: Governmental decision on sitting criteria and conditions for building large industrial facilities and thermal power plants (Zagreb TE I, TE II, Rijeka I) • 1974: Regulation on obligatory environmental impact studies for large industrial sources and thermal power plants, revised in 1985. • US experience and US regulations (Clean Air Act 1970) • Nuclear Power Plants Sitting (3 sites examined, 1980-1987) • Extensive use of point source dispersion models to define optimal stack height (Zagreb, 1970-1972, Rijeka 1974, Plomin 1980, Zenica, BIH 1986) and concentration distribution arround sources • Field experiments and measurement campaigns to support and verify models, to analyse meteorological and air pollution conditions – until 1987-1988. • 1995: First Clean Air Act
With 1995 Clen Air Act • Air quality criteria have been set but • Monitoring network has not been regulated or obligatory • Monitoring strategy has not been defined • Permitting regulation still in use
1992 • Croatia became a party to the 1979 Convention on Long-range transboundary air pollution (CLRTAP) by succession and to the EMEP protocol • EMEP: Co-operative Programme for Monitoring and Evaluation of the Long Range Transmission of Air Pollutants in Europe • Croatia participated in EMEP with its measurements at 2 sites since 1981
