I.Plan Name：The Project of Chiayi City for Strengthening Street Dust Cleaning in 2018.
II.Implement Company：Shin Shin Environmental Protection Engineering CO., LTD.
III.principal investigator：CHEN,MU-LIANG
IV.Plan Time： February 21,2018 to December 15, 2018
V.The work content completes the progress：
(I)The cleaning operation began on March 12, 2018 and, based on the statistics until December 15, 2018, the street washing operation reached 15,313.3kilometers with the length of street sweeping operation of 10,076.3kilometers as well as the cleaning execution length of 25,389.6 kilometers. The cumulative achievement rate was 100%
(II)Estimation of the street cleaning benefits in pollution reduction:
The total length of the sweeping street in this period was 25,389.6 kilometers. According to the EPA's reduction formula (reduction amount = length of sweeping street × reduction factor), total suspended particle (TSP) can be reduced to 350.38 metric tons, 66.01 metric tons of PM10 and 15.41 metric tons of PM2.5. In addition, according to the 2018 Air Pollution Control Plan of Chiayi City, the control category of the project is classified as “fugitive emission source”, which adopts a control strategy of “Strengthening Street Dust Cleaning Operation” with the reduction planning method of “Execution Street Cleaning Operation” (including the cleaning team work of the bureau). It is scheduled to perform a total cleaning length of 80,000 km, which is expected to reduce TSP 1,104.0 metric tons, PM10 208.0 metric tons and PM2.5 48.6 metric tons. The implementation of this project long with the EPA cleaning team (until December 15 statistically) with the results of a total of 80,071.4 km of washing length, is expected to reduce TSP 1,104.99 metric tons, PM10 208.19 metric tons and PM2.5 48.60 metric tons, having reached 100% of estimated objective.
(III)Census of road fouling condition:
In order to strengthen the mastery and improvement of the road dirt level in Chiayi City to serve as a reference for regular planning of the street sweep route, the project had conducted a comprehensive road census on Chiayi City's roads and streets sweeping operation every month. Road census work began in February, and a totaled 332 time/road had been surveyed by the end of December . The total number of kilometers in the census reached 840.8 kilometers. The results of the census accounted for more than 88% of Class A roads in December and 12% of Class B roads. The 42 cases (roads) were reported to have improved.
(IV)Inspection to the field operation of street sweeping:
The road inspection was carried out twice a week. The statistics of this year were up to December . Investigation to the street washing operation had been conducted for 102 times and the street sweeping operation for 80 times, and the total inspection length has reached 1,144.6 km.
