According to the report from “Civil satisfaction investigation for environmental protection policy”, the consequence of research of outdoor air quality indicated that the citizens were persecuted with the air pollution which caused by high polluted vehicles in the last year was over 70%. Due the high density of population and lack of the buffered areas between different land uses, the average vehicles owned per person was high. An average of 1 vehicle (motorcycle or automobile) was owned by each 1.1 person. In terms of statistical figures from AQMC in 2009, CO pollutant resulted from motorcycles was 77.13 percent of all CO emission in Taiwan. HC and NOx was 20.90% and49.62% respectively. Therefore, if we have a proper strategy to control and eliminate the high-pollutant emitting vehicles, the air quality could be improved effectively. In order to manage all high-pollutant emitting vehicles with limited inspectors, we established the high-pollutant emitting vehicles reporting system in 2000.This year, new functions were added and system was maintained, and total rewards worth more than one million NT dollars lottery event for tipsters was held. Above all, two training programs and two conferences took place during the duration of the project. Through the programs and conferences, environmental protection government agencies had communicated with each other and exchanged successful experience in polluting vehicle reported area and came to many consensuses. Information system functions were also modified and updated consequently, and processing quality was greatly improved. The project team developed E.P.A. “Moving Pollution Sources Information system”, included national performance E-report, and established intranet book system to maintain the information and schedules. The book system contained important check points and schedules of all projects or events. Furthermore, project team integrated databases delivered by all the projects and consolidated data to provide integrated information as an important reference for line pollutants’ decision making platform. All the consolidated information could be saved and applied for all the purposes upon different needs. According to statistics, 316,246 suspect vehicles were reported by Dec. 31, 2009. Compared with high-pollutant emitting vehicles' case in 2008, it increased by 3.37 times in 2009. It has effectively contributed to emission reduction in 2009. In motorcycle category, emission was reduced approximately 363.9 tons in NMHC and 1,341.2 tons in CO emission. In diesel vehicles category, it was reduced 394.60 tons in TSP emission. In gasoline vehicle category, it was reduced 2.62 tons in NOx emission、0.83tons in NMHC emission, and 34.87 tons in CO emission. Compare to 2008, in motorcycle category, the reduction amount increased 249.1 tons in NHMC and 889.3 tons in CO emission. In diesel vehicles category, the reduction amount increased 109.1 tons in TSP emission. In gasoline vehicle category, the reduction amount increased 1.42tons in NOx emission、0.43 tons in NMHC emission, and 18.27 tons in CO emission. The fruitful results indicated the project performed excellently among line-source pollutants strategies. The program has shown it’s valuable and should be developed further.
