2024 Chiayi City Clean Air Integrated Management Plan

英文摘要 The implementation of this plan is to grasp the long-term change trend of air quality in Chiayi City, through work effectiveness evaluation and technical support, and then develop appropriate air pollution control measures. The implementation period of this year's project is from January 1, 2024 to December 15, 2024. The summaries of the main works are as follows: Based on the 5-year monitoring data between 2019 and 2023 in Chiayi City, the AQI>100 ratio drops from 21.6% to 13.4% (38.0% improvement rate); the AQI>100_PM2.5 ratio drops from 17.0% to 7.7% (54.8% improvement rate); the AQI>100_O3_8hr ratio drops from 8.5% to 4.9% (41.9% improvement rate). As of November, the AQI>100 ratio in 2024 is 10.7%, the AQI>100_PM2.5 ratio and AQI>100_O3_8hr ratio are 6.0% and 4.8%, respectively; the red alert poor air quality station days(AQI≧151) has decreased from 3 days in 2023 to 2 days in 2024. The analysis of the 2 AQI>150 station days (red alert) events in Chiayi City in 2024 has been completed, which is an improvement from the 3 station-day events in the same period last year. In addition, the high SO2 events analysis in 2023 and 2024 has been completed by simulation and the inverse trajectory, the result shows the pollution mainly come from industrial combustion and high-altitude pyrotechnic combustion emissions in Minxiong. Chiayi City also imported Yushan visibility image observation data. The percentage of Ali Mountain visible increased from 25.2% in 2017 to 33.4% in 2023, and the percentage of Yushan visible increased from 3.3% in 2017 to 23.6% in 2023. As of Nov. 2024, It has the best visibility in June and August. Based on TEDS 12.0 database, the annual emissions in Chiayi City are PM10-649.9 tons/y, PM2.5-203.1 tons/y, SOx-30.0 tons/y, NOx-782.1 tons/y, NMHC-2,87.2 tons/y, respectively. Compared with TEDS 11.1 database, the emissions have reduced by 9.4%~28.1% (PM10 and PM2.5 increased due to the emission of road dust have increased by 25.6%~61.4%). To develope the city's air pollution control plan from 2024-2026 based on MOENV’s guidelines and reduction calculation manual, which total 34 control measures (81 strategies) are plotted. All procedures were handled in accordance with the MOENV’s schedule and guidelines, including preview notice(2024/1/29), public hearing(2024/2/7), cross-county and city consultation meeting(2024/2/20), draft submit to MOENV(2024/2/22), preliminary review meeting(2024/5/17), final review meeting(2024/7/31). Finally, the plan was approved by the MOENV on October 9, and the city officially announced it on October 14. The proejct participated in 4 sessions of “Air Pollution Interregional Cooperation Prevention Response in Southern Taiwan”, hold two sessions of “work performance review meetings”, and assisted to hold two sessions of “clean air promotion committee meetings” and prepare meeting related-materials. As of November, a total of 53 notifications of poor air quality were implemented (including holding 6 command centers). Among them, the number of PM2.5 notifications reached 37 times, O3-8hr reached 15 times, and PM10 reached 1 time. There are 7 air quality purification areas in the city. The project has promoted the adoption rate to reach 100% for 5 consecutive years; to conduct monthly reviews to report to the Ministry of Environment; to hold 1 session(2024/8/22) to entrust experts and scholars to conduct inspection and evaluation. The proejct investigated the conditions of existing 7 air quality purification areas such as hard paving, current situation, area, and tree shading to provide to management units to evaluate and set up solar systems. The "Google Earth system" and "Land Surveying and Mapping Service Cloud System" are applied to execute investigation of aerial photography of exposed bareland to build basic information, including region, land number, longitude and latitude, area, land type, and aerial photography. As of December, 21 public and 15 private lands have been recorded in East District, and it will continue to investigate the rest of public and private exposed land. A total of 10 air pollution prevention and protection advocacy activities have been held, including 5 propaganda are scheduled for seed lecturers. With rewarded quizzes or games to interact with the public, 2,208 people participated in. To use social media to publish knowledge about air pollution prevention and protection monthly. Currently, 10 advocacy news was released by press and media regularly to publish relevant knowledge on air pollution prevention and protection. In 2023, the Chiayi City's annual assessment results were assessed by the MOENV as "Excellent". Until the third season of 2024, the self-assessment of air quality improvement work performance evaluation scores 68.8, while annual evaluation scores 97.1 to seek for high scores in the end-of-year assessment.
