Abstract
This project has been implemented since May 01, 2020. As of April 30 of 2021, various supervision and verification mechanisms are carried out to ensure the quality and quantity of all task items. In addition, the task team also actively contact with other units for their implementation results to present the status of overall road washing and sweeping operations of the Pingtung County. All task items in this year have been completed in accordance with the predetermined goals and progress. The results of this year are summarized and described as the followings.
The task team conducts daily monitoring and verification operations of street washing and sweeping vehicles, including path, time, speed and water consumption. The street washing and sweeping mileage checked is 30,934.8 and 18,902.0 km, respectively, and their achievement rates are all over 100%. The number of on-site inspections of street washing and sweeping operations were 182 times. The defects of on-site inspection on street sweeping were mainly 21 times of “residual dust or garbage found after sweeping.” In terms of defects of street washing, there were mainly 9 times of "flushing width less than 3 meters," followed by "failure to operate according to the scheduled trip" and "vehicle speed not controlled within the speed limit of 20 km/hr" each counted 4 times. For deficiencies found during the inspection, the staff are required to improve immediately by verbal warnings, and discussed in the monthly work review meeting. For repeated deficiencies, the violation points will be punished and the executive staff recommended to be replaced to ensure the quality of washing and sweeping operations. A monthly survey of road pollution levels was carried out, and the road cleanliness of Class A of this year increased by 1.8% compared with that of the previous year. The average street dust loading of 1.0 g/m2 in 2020 was 0.04 g/m2 lower than that of 1.04 g/m2 in 2019, and the average silt loading of 0.27 g/m2 was 0.02 g/m2 lower than that of 0.29 g/m2 in 2019. In terms of the change in the amount of street dust by dry precipitation after 36 washing and sweeping operations, the street dust amounts by dry precipitation in the first hour after the washing and sweeping operations was reduced by 6.0 to 61.4% compared with that before the washing and sweeping operations, and the average reduction rate was 25.9%. In the second hour after washing and sweeping operations, the street dust amounts by dry precipitation was between an increase of 2.8% to a decrease of 68.2% compared with that before the washing and sweeping operations, and the average reduction rate was 19.6%. In the third hour after washing and sweeping operations, the street dust amounts by dry precipitation was between an increase of 9.9% to a decrease of 41.3% compared with that before the washing and sweeping operations, and the average reduction rate was 10.4%. The number of notifications of dirty road sections to the road authorities and to the relevant air pollution control plans were 45 and 26, respectively, all of which completed the improvement. Combine with the private road repair charity volunteer team, the 31 potholes in the roads of Pingtung City and Yanpu Township were notified by telephone, and all repairs were completed to reduce the source of road pollution. To promote the environmental protection heroes to wipe the dirt, combines with the volunteers from 16 community and river patrol teams to strengthen the cleaning of the dirty spots on the roads, and the operation dead corners of the main washing and sweeping routes of the street cleaning vehicles. The total number and length of street cleanings is 176 times and 348.8 km, respectively, which reduces the road dirty spots and improves the street cleanliness. Carrying out a questionnaire survey on people’s satisfaction with street washing and sweeping operations, the satisfaction rate was 89.5%, an increase of 2.2% from the previous year. The reduction of TSP by washing and sweeping operations was 653.9 metric tons, and the average monthly TSP loading could be reduced by 54.5 metric tons. A total of 123.2 metric tons of PM10 pollutants were reduced, and an average of 10.3 metric tons of PM10 loading per month could be reduced. This plan proposes road pollution prevention measures 3.0 with heavy farming machinery. After grasping the information of the farmland about to be plowed through CCTV, the task team will come to the farmland to conduct inspections and guidance in advance. In addition, the task team assisted the Environmental Protection Bureau of Pingtung County (PTEPB) to handle a farming machinery pollution improvement briefing, and proposed ways to improve the roads that were contaminated with soil entrained in machinery to plow farmland, including moving farming machinery with transfer vehicle, carrying long-handled iron rake, large broom and bucket, and carrying a pumping motor unit to wash the soil entrained in machinery before going on the road without transfer vehicle. This year, there were 13 farmlands plowed by farming machinery operators in Wandan Township, Xinyuan Township and Kanding Township, and the pollution prevention measures had been implemented, including carrying pumping motor to wash machinery and transfer vehicles at 3 farmlands, and carrying cleaning tools to clean the road dirt and transfer vehicles at 5 farmlands. Furthermore, People complained that the farming machinery polluted the roads and the PTEPB punished the pollution behaviors according to regulations. I In the future, it is still necessary to strengthen propaganda to farming machinery operators on road pollution prevention and control, reduce road pollution sources, and improve road cleanliness.
