To grasp the impact of air pollutants emission from special industrial zones on air quality and protect people's health, the Environmental Protection Agency established "Standard for the Establishment of Buffer Zones and Air Quality Monitoring Facilities in Special Industrial Park" in 1983.
The Standard defines special industrial classification types, buffer zones, air quality monitoring facilities, and other relevant regulations that can real-time understand air quality in neighboring Special Industrial Park. Furthermore, the Standard can evaluate whether the development of the industrial zone has unexpected adverse effects on the surrounding environment and establish basic information on air quality that provides a reference for drafting control strategy.
When there is a special industry zone with a quarter of the industrial park area, the developer should set up buffer zones around the park and air quality monitoring facilities in appropriate locations. Table 1 shows the 14 selected special industrial classification types.
Air quality monitoring
Currently, there are five special industrial parks nationwide, including Kaohsiung Linhai and LinYuan Industrial parks, Yunlin County sixth naphtha cracker Industrial parks, Taichung Science Park, Tainan Science Park. Figure 1 shows the 35 air quality monitoring stations of five special industrial parks in Taiwan.
- The setting of stations: According to the principle of selecting measuring stations specified in the set standards, at least four air quality monitoring stations shall be set up. Suppose the industrial park contains the designated specific industrial classification, including the metal smelting industry, oil refining industry, petrochemical essential raw material industry, paper pulp industry, cement manufacturing industry, the coking industry, coal, oil, or gas-fueled power industry. Should be located in the township (town, city, district) where the industrial zone is located and the township (town, town, district) adjacent to the township (town, city, section). City, district) each set at least one station.
- Monitoring items: including general air pollutants (including PM2.5, PM10, SO2, NOx, NO, NO2, CO, O3, total hydrocarbons), meteorological measurement items (wind direction, wind speed, temperature, relative humidity, rainfall). And according to the characteristics of the industries covered by the industrial zone, it is necessary to add designated air pollutant measurement items.
- Monitoring frequency: Except for dioxin, which is monitored once a year and once a month for the second to third year of the change to a special industrial zone. In other cases, automatic monitoring facility monitors shall be continuous monitoring, and manual operation monitors monitored once every six days.
Note: Linyuan industrial park and Linhai industrial park are combined to set up a total of 2 stations.;
