This project was undertaken to investigate an approach to evaluate the risk potential of hazard or odor air pollutants of industrial park for environmental or industrial agency. First, the 81 air pollutants with high potential to result in air pollution emergency have been screened by vapor pressure and odor threshold and/or acute exposure level. The screen indicators for high-risk process (Ip) and industrial parks (RP) are also evaluated, respectively. According to the score for each process and industrial park, each process or industrial park can be ranked as high, intermediate or low priority. The method of sensitive receptor area identification was conducted by using ALOHA model. In addition, total 188 and 152 potential sources that may emit the covered air pollutants have been inspected by Environmental Protection Bureau in 2009 and 2010, respectively; the coverage is 100% and 96.8%. 40 facilities visiting of six high-risk potential industrial parks have been conducted in the project. The staffs of management center of the visited six industrial parks, and 20 residents were also visited. Moreover, investigation of suspected source of petition cases on air pollution at two industrial parks was conducted by FTIR. 20 background and 18 real-time samples were also collected around the two industrial parks, respectively. Impacts of selected pollutant from four target stacks on the vicinity were simulated by air quality dispersion model. A GIS of air pollution emergency has been also set up. Five US chemical release case investigation reports and eight Taiwan’s reports were collected to figure out the potential factors that may caused high risk in processes. Base on the information, two mechanisms, the preventive and management mechanism for air pollution emergencies in industrial parks and the SOP for emergency response to air pollution incidents, have been draw up. The stack inspection has conducted in the 10 high potential facilities by GC/MS methods to measure the emitted species, concentrations, and the efficiency of air pollution control devices. Furthermore, we have assisted in two EIA reports reviewing and in two emission standard amendments. Three expert consultations, one workshop, and 10 practices of air pollution emergency incident for EPB were also been provided in this project.
