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 March 4, 2016 till December 15, 2016. 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 indicators and trends in air quality changes
Statistically, our city from 2006 till 2015, the days of station PSI> 100 have decreased from 30 days of station (NPL ratio 8.22%) in 2006 to two days of station (0.55%) in 2015, showing Chiayi City air quality has improved with the effectiveness and its air quality has also improved. In 2016, from January to November, the adverse Station Day is only one day, which is also in line with this year's air pollution control targets (less than 7 days of station, 1.92%); as for PSI <50, days of good air quality days of station. In 2006, 78 days of station with 21.4% proportion has increased to 104 days of stations (the proportion of 30.8%), showing the air quality tends to be good. In 2016, from January till November, the good days of station is 139 with the proportion of 41.5% (139 days of station/ days measured 335 days of station, which is also in line with the prevention and control target. (greater than 24.6%, 90 days)
(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 98%; fugitive sources 13 strategies, the average rate of completion reached 100%; Stationary sources 18 strategies, the average of completion rate reached 100%; among 11 strategies to promote low carbon city, the average rate of completion reached 99%, which are all in line with the progress of time process control.
(D) Promoting EPD performance evaluation
In 2015, the city's annual evaluation results in the same group of counties and cities (Keelung City, Hsinchu City, Hsinchu County, Nantou County, Chiayi City, Taitung County) was in the second place with "Premium" rating.
In statistics, the city in 2016, from January till December, the EPA performa- -nce evaluation self-assessment score was 94.8 with the completion rate of 94.8%, which are all in line with the progress of time process control.
(E) Air quality purification zone
The city was set 8 air quality purification areas with its green area reaching 11.452 hectares, with 4 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 18 and October 19, members inspected the site. In each purification zone base, Fuguo redrawing district bare ground greening projects and Chia-yu bike lane are the best ones.
