109 年雲林縣空氣品質健康戶外活動日數(AQI小於100)比例為88.6%，相較 105年 73.4%上升 15.2%；空氣品質不良(AQI>100) 比例為 11.4%，造成空品不良主要指標污染物為 PM2.5 及 O3-8hr，比例為 54.8%和 44.6%，PM2.5相較 105 年 80.3%下降 25.5%，O3相較 105 年 17.2%上升 27.4%，顯示O3為雲林縣未來需努力改善之議題；109年PM2.5紅色警戒日數為8日，相較105年80日下降90%。109年各項污染物變化率，除斗六測站O3最大小時98%高值及八小時93%高值，相較105年呈現上升趨勢外，其餘污染物皆呈現改善趨勢，然PM2.5年平均值(自動測值及手動測值)仍未達國家空氣品質標準 15 μg/m3 。 計畫執行期間空氣品質不良通報共116天次，通報相關計畫針對污染源進行相關稽查管制作為，合計共削減TSP 115公噸、PM10 20公噸、PM2.5 5公噸、SOX 55公噸、NOX 75公噸、NMHC 0.55公噸。另辦理空氣品質不良暨河川揚塵事件緊急應變大型演練作業，模擬空氣品質惡化時，環保局與相關單位處置判斷與應變能力，熟悉事件發生時之通回報流程，以提升空氣品質惡化期間應變成效。 依據環保署 109-112 年空氣污染防制方案及撰寫指引，撰寫雲林縣109-112年空氣污染防制計畫書，空氣污染防制計畫共制定3面向，14 類管制對象，32項防制措施，並協助完成專家諮詢會議、空品區減量目標協商會議及公聽會等會議，於109年10月提送環保署審查，環保署於110年3月及7月召開審查會議，目前正依委員意見修正計畫書內容。 計畫執行期間每月除彙整各計畫提交資料，並進行查核作業；另於計畫期間內辦理聯繫及專家諮詢會議，藉以提升各計畫工作績效及執行品質。除書面查核作業，並依據環保署工作績效展現考評內容，針對固定源管理資訊系統許可資料、固定源空污費暨排放量申報整合管理系統及營建工地管理辦法符合度進行現場查核及系統查核作業，藉由專門技術人員豐富與實地查核方向，提出缺失與改善建議，強化及提升委辦計畫執行成效。 本年度除持續辦理空氣品質預報作業，並於相關平台揭露，統計觀看人數達22.2萬人次，並製作空氣污染防制宣導圖卡、辦理抽獎活動及拍攝宣導短片，持續宣導雲林縣空氣品質改善作為與執行成效；另執行問卷調查作業，依調查結果顯示，針對改善空氣污染整體努力成果滿意比例為85.2%，其中認為烏賊車(76.8%)及濁水溪揚塵(51.4%)有改善比例較高，認為可有效改善空污政策為異味與惡臭改善(66.3%)、濁水溪揚塵改善(43.7%)及推動共享運具(34.1%)等三類；另外，認為需要加強宣導之策略為工廠排放污染改善(60.1%)、紙錢集中燒(51.4%)及推動綠色運具(48.1%)。

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%).
