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)
WHY 2002 ?WHY 2002 ?
Historical overviewHistorical 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
19921992
• 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
