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 strategy of "internal integration and external cooperation" to assist cross-county and city cooperation and exchanges and cross-bureau resource integration are also implemented. Assist in the implementation of the “Chiayi City Air Pollution Control Plan (2020~2023)” and “clean air promotion committee meetings”, and tracked the implementation progress of control measures; furthmore, we assisted to plan and rolling revised "Chiayi City Air Pollution Control Plan (2024~2027)" and other administrative matters related to the air pollution prevention and control business. The implementation period of this year's project is from January 1, 2023 to December 15, 2023. The summaries of the main works are as follows： 1. Air Pollution Emission and Air Quality Trend Based on TEDS 11.1 database, the annual emissions in Chiayi City are PM10-553 tons/y, PM2.5-224 tons/y, SOx-36 tons/y, NOx-1,088 tons/y, NMHC-3,951 tons/y, respectively. Compared with TEDS 10.1 database, the emissions have reduced by 7.4%~39.3%. Based on the 5-year monitoring data between 2018 and 2022 in Chiayi City, the AQI>100 ratio drops from 25.5% to 12.6% (50.5% 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 2023 is 14.1%, the AQI>100_PM2.5 ratio and AQI>100_O3_8hr ratio are 7.2% and 6.9%, respectively; the red alert poor air quality station days(AQI≧151) has decreased from 4 days in 2022 to 3 days in 2023. 2. Achievement of the Chiayi City Air Pollution Control Plan (2020~2023) This project also assisted to analyze the achievement of the Chiayi City Air Pollution Control Plan (2020~2023), including 34 control measures. As of Sep. 2022, there are 29 permanent control measures, including 20 measures attained, 5 will be attained in Dec., 4 will be unattained due to COVID-19 pandemic or policy change). The reduction achievements (achievement tatio) are as follows: PM10: 130.79ton (121%); PM2.5: 74.14ton (126%); NOx: 811.59ton (152%); SOx: 17.87ton (127%); NMHC: 686.69ton (132%). 3. Develope draft of the Chiayi City Air Pollution Control Plan (2024~2026) To develope the city's air pollution control plan from 2024-2026 based on MOENV’s guidelines and reduction calculation manual. The total 30 measures include 8 Refined industry reduction technology, 7 Comprehensive control of vehicles and machinery, 5 Establish cross-department project management, 2 Regional development and monitoring, 2 Enhanced management in specific seasons, 4 Net zero carbon policy, 1 Comprehensive management and 1 Cross-county, city cooperation project. Finally, the project assisted to conduct cross-county and city focused discussion meetings and completed the draft of the air pollution control plan (2024-2026). 4. Cross-county, city and bureau integration Chiayi City adopts the policy of "internal integration and external cooperation" to respond with multi-air pollution sources. For internal integration, the project assisted to hold two sessions of clean air promotion committee meetings; for external cooperation, the proejct participated in 11 sessions of “Air Pollution Interregional Cooperation Prevention Response in Southern Taiwan”, 2 sessions of “Yun-Chia-Nan and Kao-Ping Exchange and Consultation Meetings” and 2 sessions of “Central Taiwan Regional Governance Platform-Air Pollution Protection Group Meetings” to work with central and other local governments to improve air quality together. 5. Improve air quality maintenance plan execution performance and quality The project assisted to hold two sessions of “work performance review meetings”. The self-assessment of air quality improvement work performance evaluation scores expected to reach 95.4 in 2023. We also have assisted in reporting and uploading the first to third quarterly reports, monthly reports from January to September and Air Pollution Control Fund-related statistics. 6. Establish notifications mechanism of poor air quality In order to prevent poor air quality, the project introduced intelligent program applications to report forecast and hourly notification for poor air quality. Aa of November, a total of 67 notifications of poor air quality were implemented. Among them, the number of PM2.5 notifications reached 44 times accounted for 65.67%, O3-8hr reached 21 times accounted for 31.34%, and PM10 reached 2 times accounted for 2.99%. The reductions are PM10 6.98 ton and PM2.5 1.71ton, respectively. 7. Air quality purification areas, bare areas and green walls There are 7 air quality purification areas in the city with a green area of 4.25 HA、6.8 KM, including 3 bare green areas, 2 environmental parks and 2 bicycle lanes. The project has promoted the adoption rate to reach 100% for 4 consecutive years; to conduct monthly reviews to report to the Ministry of Environment; to hold 1 session to entrust experts and scholars to conduct inspection and evaluation. There are 18 bare areas in this city. 9 areas with better maintenance were inspected quarterly, and 9 areas with poor maintenance were inspected monthly. Currently, all 18 bare areas have been paved with turf. 4 green walls were built through funding subsidies from the Ministry of Environment, and we conduct quarterly tracking to record maintenance status. We also visited 24 schools (8 junior high schools and 16 elementary schools) that have not yet applied for funding from the Ministry of Environment to evaluate if they have appropriate places to build. The results show 13 schools have environmental greening measures with their own funds and 4 green walls funding subsidies from the Ministry of Environment, a total of 17 schools have greening measures (61% of junior high schools and elementary schools in Chiayi City). 8. Enhance air pollution prevention and protection advocacy activities A total of 11 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, 3,227 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, and to plant the concept ”Green Life, Good Air “ in the hearts of citizens.
