This project applied so called “Stepwise emission sources searching technique” in Lin-Hai Industrial Park and No. 6 Naphtha Cracking Project Industrial Park to investigate potential air pollution sources in the adjacent area, and a total of 1,152 hours of continuously OP-FTIR monitoring was completed by the task. The fugitive emission from oil storage tanks located at D area of CPC Dai-Lin Plant may result in high concentration of gasoline in an elementary school in the vicinity for Lin-Hai Industrial Park. High concentrations of VOC in the north town of Mailiao Industrial Park may come from the flare emission of P01 and P02 Plants which located in the park. The amount of VOC emission was estimated for being reduced 567.82 tons after the correction action completed by the P580172 wastewater treatment plant, which was identified as a major emission source in the previous year. Emissions rationality auditing was conducted in ten factories and several problems were identified by the auditing. Among those problems, six were related to operating permit, four related to emission reporting, and two related to compliance. As a result, a series of amended measures were proposed to EPA. Besides, two petrochemical plants were inspected by TVA-1000 to check for the equipment leakage rate. One of them called H48035 was identified as having 32 components with leaking concentrations exceeding 10,000ppm which was account for the leakage rate of 5.89%. In addition, 41 equipment components were inspected by the blow-through method to check for the equipment leakage rate. The results indicated the emission factors were better explained by utilizing “EPA Correlation Approach”. The auditing of rule compliance has been carried out at two large petrochemical plants; the result shows those plants have met the requirements of the emissions rationality auditing. Moreover, six VOCs water samples were collected at two cooling tower sites, and over 10 thousands equipment components and storage tanks were inspected by TVA-1000 coupled with Infrared Gas Finder to check for the equipment leakage rate. In addition, three project materials including National Air Toxics Trends Station Network, Community-scale Air Toxics Ambient Monitoring Program, and Schools Air Toxics Monitoring Initiative have been reviewed, and draft standard operation procedures for air toxics ambient monitoring on sensitive receptor have been derived from the reviewing process.
