This plan was implemented from May 1, 2020 to April 30, 2021, and a short advocacy video was shot at the end of May due to the impact of COVID-19. The implementation results of the main work items are summarized as follows:
In 2020, the proportion of outdoor activity days with healthy air quality (AQI<100) in Yunlin County was 88.6%, which increased by 15.2% when compared with 73.4% in 2016; and the proportion of outdoor activity days with poor air quality (AQI>100) in Yunlin County was 11.4%. PM2.5 and O3-8hr were the main pollutants causing poor air quality, accounting for 54.8% and 44.6%, respectively. PM2.5 was decreased by 25.5% when compared with 80.3% in 2016, and O3 was increased by 27.4% when compared with 17.2% in 2016, indicating that O3 is an issue which could be improved by Yunlin County in the future. There were eight days with red alerts for PM2.5 in 2020, decreased by 90% from the 80 days in 2016. In 2020, except for the high change rate of maximum hourly O3 concentration of 98% and the high change rate of 8-hour O3 concentration of 93% at Douliu observation station, increased compared with those in 2016, other pollutants were reduced, but the annual average PM2.5 concentration (automatically measured value and manually measured value) still did not meet the national air quality standard of 15 μg/m3.
During the plan implementation, a total of 116 days with poor air quality were reported. Based on these reports, the pollution sources were inspected and controlled. A total of 115 tons of TSP, 20 tons of PM10, 5 tons of PM2.5, 55 tons of SOX and 75 tons of NOX were reduced. In addition, large emergency response drills were carried out for poor air quality and river dust events. In simulating air quality deterioration, the environmental protection bureau and relevant units should be able to handle emergencies and make judgments and responses, and be familiar with the report and reply process in the case of events to improve the response effect during air quality deterioration.
Based on the Guidelines for 2020-2023 Air Pollution Control Program and Writing of the Environmental Protection Administration(EPA), the 2020-2023 Air Pollution Control Plan of Yunlin County has been written to develop 3 aspects, 14 categories of control objects and 32 prevention measures and help to have expert advisory meetings as well as consultation meetings and public hearings on reduction targets of air quality areas. The program was submitted to the EPA in October 2020 for review. The EPA held review meetings in March and July of 2021, and the plan is currently under revision according to the opinions of members.
The data submitted were collected and inspected each month during the plan implementation, and experts were contacted for expert advisory meetings during the plan to improve the performance and quality of implementation of all plans. In addition to the written inspection and the evaluation made according to the performance of the EPA, the on-site and system inspections were carried out according to the conformity among the fixed source management information system permission data, the declaration and integrated management system of fixed source air pollution fee and emission as well as the construction site management method, based on the rich on-site inspection directions of specialized technicians.
In this year, air quality was continued to be forecast and released on relevant platforms, 222,000 viewers watched the video according to the statistics, air pollution control advocacy cards were made, lottery activities were held, an advocacy video was shot, and the air quality improvement and implementation were continued to be advocated in Yunlin County. Moreover, a questionnaire survey was conducted. According to the survey results, 85.2% of the respondents were satisfied with the overall results of the efforts to improve air pollution, among which cars with heavy exhaust emissions (76.8%) and dusts from Jhuoshuei River (51.4%) were considered to be significantly reduced. The three policies considered to be effective in improving air pollution are improvement on odor and stench (66.3%), improvement of dust from Jhuoshuei River (43.7%) and vehicle sharing (34.1%). In addition, the strategies considered to be greatly advocated are improvement of factory emissions (60.1%), concentrated burning of joss paper (51.4%) and promotion of green vehicles (48.1%).
