1.Statistics of the street washing project was conducted from May 1, 2018 to April 30, 2019. The cumulative length is 67,933.7 km with a total completion rate of 100%. The estimated TSP reduction, PM10 reduction, and PM2.5 reduction was 937.49 ton, 176.63 ton and 41.24 ton, respectively. 2.On-site inspections were carried out every month. The statistical period was from May 1, 2018 to April 30, 2019. In a total of 147 inspections, the total length washed was 3,674.3 km, and the average street washed per month was 306.2 km, with the completion rate of 100%. 3.For manual environmental clean-up operation, the accumulative length reached 2,210 km, and the completion rate was 100% during the statistical period from May 1, 2018 to April 30, 2019. 4.In this project, the first education training session for street washing operators was conducted on May 8, 2018, and another one session of post-mid-term education training session was conducted on January 30, 2019. A total of two sessions of education training were completed, with a progress completion rate of 100%. 5.The dust-raising period of Zhuoshui River occurs during the northeast monsoon every year, resulting in poor air quality in surrounding area. In order to promote the concept of dust prevention among the public, the education and promotion of dust prevention and control in towns and villages or on campus were conducted when the air quality turns bad. A total of 10 times of promotion meetings had been conducted, with a total number of participants reaching 662 people and progress completion rate of 100%. 6.For the real-time alerting monitoring system, 3 cameras were set in July 2018 and another 3 in September 2018. A total of 6 cameras had been set, with a completion rate of 100%. 7.Statistics from May 01, 2018 to April 30, 2019 showed that 102 times of responding street washing operations were carried out with the total length of 9,716.4 kilometers. The estimated TSP reduction, PM10 reduction, and PM2.5 reduction was 134.09 tons, 25.26 tons, and 5.90 tons, respectively. 8.Three greening operations in total had been completed, with a completion rate of 100%. The site for greening included: exposed land on the eastern side of the southern bank of Xiluo Bridge (over 1 hectare), low beach of Zhuoshui River in front of Yueti Road No.74, Erlun Township (over 1 hectare), and high beach of Zhuoshui river in front of Yueti Road, No. 40, Lunbei Township (over 1 hectare). 9.In order to understand the change of dusting in Zhuoshui River during the northeast monsoon and to analyze the concentration of particulate matter (PM10) when the air quality turns bad, real-time sampling analysis of PM10 was conducted. 15 sampling in total were completed in October 2018 and January 2019, with a completion rate of 100%.
