Abstract All tasks of this project are accomplished in terms of quality and quantity in order to keep track of the street sweeping and flushing efficiency in Pingtong County. The executive performances are summarized as follows: A. The supervisory and auditory teams were established when the project started on May 15, 2008. Then lots of useful forms were created and trainings were given to those who work in the project. B. According to the cleanliness degree of the peripheral roads along Pingtong and Chaojhou test locations, most labor was focused on relatively dust-laden roads in an attempt to enhance the sweeping and flushing frequency. Until the November 2008, the team members of this project had conducted seven times of visual judgments, and seventy times of virtual tests of street dust loadings. C. Supervision and efficiency evaluation 1. With the help of camera equipments, record all the conditions of road dusts before and after flushing. Each street flusher is equipped with a GPS, keeping track of its sweeping and flushing locations and thus enhance working efficiency. 2. TSP tests were monthly carried out along the peripheral roads of Pingtong and Chaojhou test locations. Till the November 2008, 24 times of TSP tests were conducted. Tests report surveyed that street sweeping and flushing efficiency has direct influence on the reduction of particle air pollution. TSP reduction rates go between -11.4 and 28.1 ug/m3. 3. Till the December 14 2008, the team had swept streets of 8,709.3 kilometers in length and flushed streets of 11,781.4 kilometers in length. On the average, the team sweep 311.0 kilometers per week and flush 420.8 kilometers per week. D. Report of road cleanliness in Pingtong was monthly handed to local Environmental Protective Bureau. E. The team had completed the impromptu tasks which Pingtong Environmental Protective Bureau gave and had help to supervise street sweeping and flushing performance and provide timely helps. F. The team had no change in personnel during the whole project. G. All equipments in need were well prepared as the contract required when the project began. H. According to January to October 2008 gross sweeping and flushing mileages, TSP reduction rate was 1,461.8 tones. TSP emission reduced at an average of 132.9 tons per month. I. The team compiled monthly supervisory and auditory reports, and handed them on time to Pingtong Environmental Protective Bureau before the 15th day of every month
