1. Air Quality Status and Analysis:(1) In the recent years(2017~2022), the rate of poor air quality (AQI>100) in Taiwan was increased from north to south, and the main pollutants were particulate matter and ozone. Kaohsiung and Tainan’s rate of poor air quality were the top 1 and top 2 in six municipalities because of their geographically location in the downwind of Taiwan. (2) The rate of poor air quality (AQI>100) 2021 in Tainan was higher at the same time last year . First quarter in 2021 of deteriorating air quality event were mainly attributable to the impact of meteorology and other emissions , leading to air pollution accumulation around the west of Taiwan , in addition to economic recovery had been further aggravated the situation. The rate of poor air quality (AQI>100) from January to May of 2022 , Taiwan was 8.38% and Tainan was 5.8% , major air pollution were PM2.5 .
2. Emergency Management of Poor Air Quality:(1) In order to reduce air pollution, we had established emergency management mechanism of poor air quality, including announcement and inspection relevant industry. During the execution of the plan, we executed emergency management for 92 days due to deterioration warning level two. According different condition which including wind direction, pollution and warning area, we had inspected 292 factories in total and find out 27 factories’ violations. The violations had 87.0% of control equipment had not operating as required , 10.0% of data recording issue and 3.0% of operating without obtaining an operating permit. According to statistics, the total reduction of TSP was reduced 446.2 metric tons, PM10 reduced 186.9 metric tons, PM2.5 reduced 37 metric tons.(2) Cooperate in participating in Yunjianan related meetings and related meetings of the Environmental Protection Administration's cross-regional cooperation prevention team for air pollution in poor air quality seasons. We participated in 14 meetings and completed 6 joint inspections in total.
3. Pollution source tracking and detection:(1) Executed infrared gas imaging camera detection 10 times for detecting high pollution emission potential factory leak. The result indicated that there had 3 sites leak of 10 industries factories . and had been improved in limit of time.(2) Volatile organic gas inspection and testing for equipment components had been executed for 8,000 points, which including 1,340 points(16.75%) for difficult detection and 39 difficult detection points exceeding emission standard in different 3 industry with accumulated fines reaching NT$3,780,000.The failure rate for normal and difficult points was 0.51% and 0.37%. In addition, infrared gas imaging camera detection had been executed for 16 days for cooperating with volatile organic gas inspection.(3) Executed UAV(unmanned aerial vehicle) missions 10 times, which including 8 times inspection for field burning and construction site , with accumulated fines reaching NT$150,000. 2 times monitoring for industrial area. In monitoring missions, UAV, which carried air box, had detected relatively high value of PM2.5 and PM10 in a part area of Bao'an Industrial Area at morning.(4) Executed 2 factories of 4 pipe times of volatile organic compound (THC) inspection were completed for the emission pipelines , with accumulated fines reaching NT$100,000.
4. Strengthen the advocacy work during the deterioration of air quality:(1) Executed Real-time monitoring of air quality monitoring data, and assisted to post news information and initiating response actions. A total of 8 environmental news have been published.(2)Assisted to publish air pollution control results, air quality science knowledge and air quality serious deterioration reminders on Facebook. A total of 43 air quality messages had been published on Facebook.
