In order to actively and effectively use air pollution control fees to improve the city's air quality, and strive for success in the EPA's performance appraisal system, by implementing this project as a way to integrate the city's air quality improvement and maintenance sub-projects, we track the progress of the pollution prevention strategy and make recommendations in a timely manner to achieve continuous improvement of air quality. The implementation period of this year's project is from January 31, 2019 to December 15, 2019. The work progress is counted to November 30, and the time ratio is 92%. The implementation project and interim report have been submitted according to the contract. At present, the progress of each work is 100% on average. The summary of the implementation results of the main work items is as follows： (A) Air quality data collection and analysis The data on meteorological and air quality status of the city and various air pollution control areas in the past five years, via the air quality index average (AQI), the air quality of Yunjianan air quality area improved, up to 13%, Chiayi City also with an improvement trend of 18.3%; the indicator pollutants affecting air quality, the overall Yunjianan air quality area has a higher proportion of fine aerosols, close to 70%, followed by ozone for 8 hours. The difference between Chiayi City and the air quality area is not Large, showing that fine aerosols are pollutants with major air quality improvements. In 2019, the red alert event of AQI≧151 in Chiayi City was 11 station day, which is in line with the 19 station day of the year's control target, and has been improved compared to the 19 station day in the same period of the previous year. The air quality of AQI ≤ 50 is 107 station day. The target achievement rate was 111%, and it increased compared to the 107 station day in the same period of the previous year. The average concentration of fine aerosols was 23.0μg/m3 from January to November this year, which was improved from 24.1μg/m3 in the same period of the previous year, which shows that the current air quality status of this year has a continuous improvement trend compared with previous years. (B) Analysis of pollution attributes of various emission sources According to the TEDS 9.0 emissions data updated and mastered by this project review, the air pollutant emissions of the city are suspended particulates (PM10) 1,167 metric tons, fine aerosols (PM2.5) 491 metric tons, and sulfur oxides (SOX). 44 metric tons, 2,283 metric tons of nitrogen oxides (NOX), 4,004 metric tons of non-methane hydrocarbons (NMHC), 4,891 metric tons of carbon monoxide (CO). When the medium and fine aerosol emission source categories are 185 metric tons of road transport emissions, the proportion is the highest, accounting for 37.7% of the total, of which diesel vehicles with 98 metric tons (19.9%) are the highest; the second largest source of emissions is the construction of spreading sources mainly. The emissions are 179 metric tons, accounting for 36.5% of the total, of which 90 metric tons (18.3%) is the highest in vehicle emissions, followed by 70 metric tons (14.3%) for construction. The third largest source of emissions is commercial (Catering industry - soot), emissions of 87 metric tons, accounting for 17.7% of total emissions. In response to the control measures against pollution prevention measures, including: 1. Accelerate the reduction of diesel vehicle exhaust emissions, the strategy including the elimination of the first and second phases of the old diesel vehicles, the replacement of the third phase of the diesel vehicles or the installation of filter filters (air pollution control facilities) ), the use of the fifth phase of diesel vehicles; 2. Reduce the emissions of vehicles, the strategy including strengthening street dust cleaning, integration of enterprises, construction projects to implement road adoption and cleaning and maintenance, strengthening pollution prevention and control of construction projects to improve pollution reduction rate after control, build dust control at the entrance and exit of the construction site to reduce the source of dust pollution on the road surface; 3. Increase the number of fume control devices installed in the catering industry. The strategy includes propagating the concept of pollution prevention and control of new operators, counseling the catering industry to set up pollution prevention and control equipment, and supervising the implementation of improvement by the industry and reducing the public's feelings and promote the improvement and reduction of soot pollution. (C) Review and track air pollution prevention and maintenance strategies From January to November of this year, the city's air pollution prevention and control strategy promotion in the current situation includes 16 strategies for fixed pollution sources with a total of 91%; a total of 11 strategies for mobile pollution sources, with a completion rate of 79%; and 14 strategies for total emissions sources with the achievement rate 94%; the low-carbon cities have a total of 11 strategies, and the achievement rate is 81%; the comprehensive improvement/convenience measures are 10 strategies in total with the achievement rate 92%. (D) Promoting the performance evaluation of the Environmental Protection Agency The results of the performance evaluation of the city in 2017 and 2018 were evaluated by the Environmental Protection Agency of the Executive Yuan as "Top of Mobile Pollution Control" and "Excellent Performance of Mobile Pollution Source Control". Statistically, the city's 2019 (as of till September) EPA performance evaluation scores are 16A, 1B, 2C respectively, with the full score standard 19A with the achievement rate is 84%. Compared with the previous year's score of 14A, the achievement rate reached 57%. Until December 15th, we continue to urge all air quality improvement and maintenance sub-projects to jointly strive for excellent performance evaluation results. (E) Air quality purification area There are 7 air quality purification areas in the city, with a green area of 10.57 hectares, including 3 bare green areas, 2 environmental parks and 2 bicycle lanes. In the current year, through the self-assessment and the assessment of the members' committees, the current situation of the management and maintenance of the air quality purification area will be mastered. On May 16th and September 18th, the members have surveyed and the bases including " The air quality purification zone of Jiayou Railway Road " and " The air quality purification zone of Central Plaza", " The air quality purification zone of Xianghu Park)", " The air quality purification zone of Gongyi Road ", " The air quality purification zone of Fuguo " these five places as the best examples with maintenance and management results.
