The implementation of the project commenced on January 1, 2020 and terminated on December 31, 2020. The outcomes of each work item are summarized as follows: I. Road Cleaning for Dust Control As of December 31st, a total of 6,809.79 kilometers of roads were washed, with a total of 7,112 tons of water used. A total of 6,508.32 kilometers of roads were swept, with a total of 34,250 kilograms of dust collected. The total length of roads cleaned was 13,318.11 kilometers. Based on the calculation of EPA (amount of reduction = length of roads cleaned x reduction coefficient), it was estimated that the road cleaning operations reduced 183,790 kilograms of TSP, 34,627 kilograms of PM10, and 8,084 kilograms of PM2.5. II. Education ＆ Training and Internal Performance Review Meetings On January 20, 2020 (one month into the implementation of the project), one education and training session was organized for project members on the fourth floor of the Chiayi Office of Century Engineering Consultant Co., Ltd. The content of the session included the operation and maintenance of road sweepers and washers, the management of operational safety and health, road safety, and traffic accidents and insurance claims. Six internal performance review meetings were held on February 20th, April 23rd, June 18th, August 20th, October 15th, and December 10, 2020, respectively. The meetings focused on key points and critical matters of annual work, accumulated work performance and the progress of work to be improved, objectives and key points of the works scheduled for the next two months, extempore motions, and comprehensive discussions. III. Comprehensive Road Inspections and On-site Work Inspections To better understand and improve the ratings of roads in Chiayi County, and to serve as a reference for the planning of regular road cleaning routes, this project carried out a comprehensive inspection of cleaned roads in the county on a monthly basis. As of December 31st, a total of 245 cleaned road sections measuring a total length of 2,282.8 kilometers were inspected. The results included 84.08% of Level A roads and 15.92% of Level B roads. According to the specification of the contract, at least ten on-site work inspections were conducted on cleaned roads every month. As of December 31st, 23 inspections and 100 inspections were conducted for road washing and road sweeping, respectively (including 76 inspections by district offices). The total length of inspected road sections reached 79.7 kilometers. IV. Coordination Meetings for the Division of Authority and Responsibility To integrate the road cleaning capacity of the county, two coordination meetings were held on April 16th and September 17th, respectively, to clarify the authority and responsibility of related works. Representatives from the Shuei Shang Branch of the Directorate General of Highways, Maintenance Section and Engineering Section of the Department of Construction of Chiayi County Government, Air Quality and Noise Control Section and Waste Management Section of the Environmental Protection Bureau, and district offices of the four townships of Dalin, Minsyong, Singang, and Pozih were invited to the meetings to coordinate and determine the division of road authority and responsibility, as well as strengthen the horizontal reporting mechanism for road emergencies, so as to improve the overall road environment in the county. V. Horizontal Reporting of Dirty Roads The horizontal reporting mechanism of Chiayi County Road Emergency Response Team was established through the coordination meetings. As of December 31st, four cases of oil pollution, four cases of fallen road trees, three cases of damaged curbstones, four cases of soil pollution, one case of fallen bamboos, one case of fallen signs, two cases of potholes and damaged roads, one case of accumulated seeds, one case of slippery roads, one case of road works, two cases of cement pollution, two cases of accumulated fallen leaves, one case of accumulated grass residuals, one case of car accident, and one case of paint pollution (a total of 29 cases) were reported to the competent authorities for handling. Vehicles of the project participated in the improvement of dirty roads 25 times. The total number of horizontal reporting was 54 cases. VI. Promote Road Adoption to Enterprises To improve the road cleaning capacity of the county, as of December 31st, the project invited twelve enterprises to adopt roads for washing and sweeping. The length of road washed was 1,205.96 kilometers, and the length of road swept was 1,180.13 kilometers. The total length of road cleaned was 2,386.09 kilometers. Based on the calculation of EPA (amount of reduction = length of roads cleaned x reduction coefficient), it was estimated that the road cleaning operations carried out by enterprises reduced 32,928 kilograms of TSP, 6,204 kilograms of PM10, and 1,448 kilograms of PM2.5. VII. Road Dust Load Inspection As of December 31st, 32 road dust load inspections were carried out in four quarters of the year. The inspections took place at the Dalin section, Minsyong section, and Shuei Shang section along National Highway No.1; County Highway 159; County Highway 162; County Highway 168; and Wenming Road. The results showed that after cleaning, all these sections remained Level A roads. VIII. Advocacy and Administrative Compliance As of December 31st, the project maintained and updated the webpage of Chiayi County Privately-operated Road Cleaning Project by the 5th of each month. In compliance with administrative works, it submitted the water refilling records, water usage records, and on-site work inspection information of the previous month, and actual work progress of the current month and scheduled work process of the next month. It also submitted the statistics on the amount of disposed wastes of the previous month by the 10th of each month, as well as changes in the cleaning schedule of the current month and the cleaning schedule of the next month by the 25th of each month to the EPA for future reference. During its implementation, the project submitted road cleaning information 12 times.
