Based on Environmental Protection Agency’s (EPA's) proposed site selection principles, the 800 air quality microsensors were deployed in 2019, which covers 21 industrial zones/industrial settlements and priority concern areas. Field test and laboratory verification test were carried out in June, 2019, and consistency comparison test of 18 batches of air quality sensors was conducted in Tainan test station and Hsinying test station in September, 2019. After the test results were approved by Industrial Technology Research Institute (ITRI), deployment was carried out.
Two inter-bureau coordination meetings were held on 16 September and 28 October, 2019, respectively, after which a joint investigation was scheduled for each unit. According to the contract, the project was originally scheduled to be completed before September 30, 2019. Due to force majeure, the application was extended to November 30, 2019, and the project was approved by the Environmental Protection Bureau (EPB). On November 29, 2019, the deployment of 800 sensors and 108 anemometers was completed. The number distribution of microsensors and anemometers in each region is shown in the table.
According to the EPA's “Air Quality Sensor Design, Deployment and Maintenance Code”, 900 units of equipment are inspected quarterly. By the end of 2020, all the inspection operations had been conducted to replace the equipments or clean the inlet and outlet that did not meet the standards. In addition, three performance checks and sampling tests and one equipment recall test had been conducted in cooperation with the EPA. In September, 2019, too low concentrations of PM2.5 in the atmosphere, causing the performance check satisfaction not reach 90%. In the future, it is suggested to conduct the check when the concentration of PM2.5 is higher (cold season).
From August, 2019 to December, 2020, the monthly data integrity rate of sensors was above 90%. In addition, the "Tainan City Air Quality Sensor Internet of Things Information Management and Application Platform" (hereinafter referred to as the "Reverse trajectory Analysis Platform") will be set up to provide service during the planning period, carry out reverse trajectory analysis of factories with suspected pollution sources, and provide the list of inspection suggestions to the EPB in the monthly report. From January to December, 2020, 43 air pollution cases were audited and punished according to the recommended list of the Reverse trajectory Analysis Platform, and the total amount of punishment notification issued was NT$5.55 million. The distribution area of the punishment is shown in the table
The promotion meeting for the public session and professional education training of air quality and air pollution awareness were held on 28 and 31 December, 2019 respectively, and three sessions of promotion meeting of microsensor high value notification control procedures through monitoring industrial areas were held on 12, 21 and 27 May, 2020, respectively; 21 industrial/industrial settlement operators were invited to explain the content and inspection mechanism of microsensor high value notification control. From the end of May, 109, high-value notification was carried out for industrial zones to promote operators' self-management, and an inspection initiation mechanism was formulated; between June and December, the EPB has reported three factories in the industrial zones where the inspection was initiated.
From April to June, 2020, 10 CCTV was deployed, including 5 factory pollution sources and 5 open burning pollution sources (include 2 places of burning straw and 3 places of waste). Through comparing the timing of microsensor high value to query image pollution, smoke discharge was found in Tinghsin Metal Company and Taiwan Cement Company in Taiyi Industrial Zone, which have extracted to provide the reference for the follow-up factory inspection conducted by the Environmental Protection Bureau.
