A new fenceline standards of 25 VOCs were suggested to EPA based on the results of field study. The concentrations of these 25 VOCs were measured to be ranging from 1.4~4,578.4 ppb. Per Air Pollution Control Act for Semiconductor Industry, no major change was recommended regarding the emission standards and the abatement efficiency of air pollution control systems, except a minor change on source testing and pollutants to be monitored. However, we also recommend adding VOC emission limit for single stack. Per Emission Standards for Surface Coating for Motorcycle Body, by adapting reporting annual raw material usage and its VOC content will help solving problems of calculating the projected area motorcycle body and measuring the uncontrolled quantity of paint. Regarding to the principles of achieving 80 % emission reduction, 19 different processes were selected to inspect and control in future. Three petrochemical factories were selected and inspected for the leakage rate on equipment units. The results showed that totally 7 sites and 6 sites of equipment units were found to exceed 10,000 ppm in OL-1 and OL-2, respectively. According to the results of leakage rate calculation, significant discrepancies were identified for the amount reported by the factories and the amount inspected by the EPA. The discrepancies of emission quantity were identified as 43.635 tons for OL-1, 43.831 tons for OL-2, and 3.195 tons for AN, respectively. According to the results of FTIR fenceline measurement, the concentration of 5 factories was identified to exceed fenceline standards. The results of infrared camera showed that 37 obvious leakage sites were found. The leakage rate was 0.29 %, which was 2 times more than the leakage rate in USA. By guiding and improving the petroleum stations and petrochemical factories to fix with there leakage problems, a total of 457 ton /year of VOC emission were reduced in 2006. The testing of oil leakage rate showed that 20.4% was deemed “disqualifies”. Upon assisting petroleum stations to enhance there operation and maintenance skills for the oil recovery system, the disqualified rate was declined to 9.9%. The initial testing of oil/gas ratio showed that the disqualify rate was 15.9%, and upon repair of mechanical faults, the disqualified rate was declined to 9.3%. In order to assist the owner of petroleum stations to establish self-diagnosis and repair skills, we composed 6 items of standard operating procedure (S.O.P.) as maintenance guidelines. In aspect of initiating verification system for kitchen soot abatement system, we suggested adopting the method of Hong Kong, which recommended that the oil temperature should be controlled at 350℃. The kitchen soot was analyzed by using the ultrasonic extraction and Soxhlet extraction methods, the soot concentrations were significantly reduced by 14.55% and 16.08% in average, respectively. The analyzing results indicated that the Soxhlet extraction method should be replaced by the ultrasonic extraction method.
