(4) Installation of Pollution Monitoring Network

3.progress in Technology-Based Controls

Knowledge of accurate conditions of contamination is fundamental to the control of air pollution. To this end, Mie Prefecture started Japan's first continuous measurement of SO2 using automatic analyzers in 1962, and subsequently, in 1966, introduced constant monitoring by analog telemeter systems at 4 places.
Later, in 1973, a prefectural ordinance was issued to impose 16 major plants obligatory insta11atian of digital telemeter system (emission-source telemeters) for transmitting data on air pollution parameters to the Environmental Science Institute of Mie Prefecture. The plants were requested to submit detailed source data such as fuel types in use, fuel consumption, flue gas volume, and S02 concentration through the telemeter systems so that the emission volume from each plant can be noted for effective enforcement of the areawide total pollutant load control.
In addition to the above, a photochemical pollution predicting system that dispatches predictive pollution-related information to each plant to have them take effective precautionary measures for reducing pollutant emissions was also introduced in 1991.
