In order to actively and effectively use air pollution control costs to improve the city's air quality, and strive for success in the EPD's performance appraisal system, the implementation of this program integrated various air quality improvement sub-program results, also track the pollution control strategy implementation progress, and raise proposals in due course to achieve the purpose of continuous improvement of air quality. This year's program execution period started from February 9, 2018 till December 15, 2018. At the implementation of the final phase, in the proportion of the time 100%, according to the contract, the final report should be submitted. The work progress reached 100%, and the focuses of the work program in the implementation of the outcomes are summarized as follows：
(A) Air quality data collection and analysis
In the year of Red Alert Day of AQI≧151 in Chiayi City in 2018, the target of prevention was less than 24 days, which was less than 6.5%. Statistics of Chiayi City 's achievement in 2018, the number of days for air quality measurement totaling 344 stations, and the number of red guard days for 16 stations, a ratio of 4.8%, which meets the target of prevention and control of 6.5%; and the improvement over the previous year (2017) of 5.50%. The annual ratio of red alert days has continued to improve, indicating that air quality has improved.
(B) Various types of pollution sources attribute analysis
According to the program update and review of the TEDS 9.0 emissions data, in 2013 the city's (emission base year) emissions were suspended particulates (PM10) with 1,167 tons, fine suspended particles (PM2.5) with 491 tons, sulfur oxide matter (SOX) with 44 tons, nitrogen oxides (NOX) 2,283 tons, non-methane hydrocarbons (NMHC) with 4,004 tons, and carbon monoxide (CO) with 4,891 tons. Compared to the previous version (TEDS8.1, 2010), the emissions of granular pollutants (PM10, PM2.5) have increased; the increment industry has produced them increasingly, the pollution management of which must be paid attention to.
Measures are to strengthen the construction pollution control measures, including：1. Improve construction engineering pollution reduction rate (high efficiency prevention and control measures), 2. Enhance the construction engineering consistent management, 3. Improve construction engineering controlling ratio 4. Promote road construction adoption and green fence landscaping, 5. Improve street dust sweeping and washing work.
(C) Reviewing and tracking air pollution control maintenance strategy
Take the current year from January to December for example. As for the city's air pollution control policy promotion status, among the mobile sources 11 strategies, the average of completion rate reached 81.8%; fugitive sources 14 strategies, the average rate of completion reached 97.4%; stationary sources 16 strategies, the average of completion rate reached 94.1%; among 11 strategies to promote low carbon city, the average rate of completion reached 100.0%, which are all in line with the progress of time process control.
(D) Promoting EPD performance evaluation
In 2017, the Chiayi city's annual assessment results were assessed by the EPA of the Executive Yuan as “Top Tips for Mobile Pollution Source Control”.
In statistics, the city in 2018, from January till December, the EPA performance evaluation self-assessment score was 14A、4B with the completion rate of 78%, and the air Pollution Fee system appropriation 60% level(10A) , the completion rate of 100%.
(E) Air quality purification zone
The city was set 7 air quality purification areas with its green area reaching 10.57 hectares, with 3 exposed green places, 2 green parks and 2 bike lanes. This year after the self-assessment, the Commission assessment methods, we easily master the purification zone base management and maintenance status; On May 16 and September 20, members inspected the site. In each purification zone base, Old Chiayi Hospital Barely Landscaping Project (Central Plaza) , Po Ai Park and Fu Kuo bare land greening project.
