According to the report from “Civil satisfaction investigation for environmental protection policy”, 53% of the returned questionnaires indicated dissatisfaction of the existing air quality. 58.1% of the returned questionnaires indicated that the main reason caused the air quality to worsen was due to the exhaust from vehicles. Due the high density of population and lack of the buffered areas between different land uses, the average vehicles owned per person is high. Every 1.1 persons owned 1 vehicle (motorcycle or automobile). According to statistical figures in 2006, CO pollutant resulted from motorcycles was 73 percent of all CO emission in Taiwan. HC and NOx was 28% and 24% 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 1999. This year, new functions were added and database was updated, 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, 93,964 suspect vehicles were reported by Dec. 31, 2008. That is 23.3% higher than 2006. It has contributed to emission reduction in 2008. In motorcycle category, the measure of reported suspect motorcycles has contributed 114.8 tons in NHMC and 451.9 tons in CO elimination. In diesel vehicles category, the measure has contributed 285.5 tons in TSP elimination. In gasoline vehicle category, the measure has contributed 1.2 tons in NOx elimination、0.4 tons in NMHC elimination, and 16.6 tons in CO elimination. 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.
