本計畫執行之主要目的在於瞭解雲林縣空氣品質現況及污染成因、檢討年度空污執行計畫成效與方向，檢視污染物減量成效以達到改善空氣品質之目標、配合環保署推動空氣污染管制規劃，研擬空氣品質改善方向，規劃短中長程管制目標，提供雲林縣環保局未來執行空氣污染管制之建議方針。本計畫自 108 年 4 月 24 日執行至 109 年4 月 23 日止，執行摘要說明如下。 排放量現況與掌握方面，依據TEDS10.0雲林縣105年TSP、PM10及PM2.5 總排放量分別為15,491、6,994及2,869公噸，TSP及PM10主要排放源為裸露地表、家庭及農林漁牧業；PM2.5主要排放源為製造業、陸上運輸業、家庭及農林漁牧業；SOX、NOX、NMHC 及 CO 年排放量分別為 8,979、25,861、18,120及 32,161 公噸，SOX、NOX及CO以製造業排放量最多，NMHC以家庭及製造業為主。 空氣品質改善方面，統計雲林縣轄內四座空氣品質監測站數據顯示，PM10年平均濃度呈現逐年改善之情形； PM2.5年平均濃度雖超過空氣品質標準(35μg/m3)，然具逐年改善之情形；SO2及NO2歷年平均值變化差異不大，亦呈微幅下降之趨勢；O3最大小時第8大值，斗六及崙背呈現上升之趨勢，反之，麥寮及臺西則呈現下降之情形。空氣品質指標(AQI)，108年良好日(AQI<100)比例達83.3%，較104年70.4%，上升12.9%。PM2.5紅色警戒日數為25站日，亦較104年116站日減少91站日。 空氣品質惡化應變作業方面，執行應變天數共145天，指標污染物以細懸浮微粒為主。當空氣品質預報不良時，則依據雲林縣訂定區域空品惡化防制措施，啟動空氣品質不良通報、查處及回報作業，透過各計畫對重大污染源之掌握及相關污染熱點之查處，並同時要求各污染源配合進行減產及提升各項污染防制措施，合計共削減TSP 229公噸、PM10 43公噸、PM2.5 10公噸、SOX 17公噸、NOX 4公噸、NMHC 23公噸。 空氣品質維護或改善計畫績效管理方面，每月彙整各計畫提交結果，並針對各計畫執行內容、各項考評指標項目執行進度及繳交資料品質進行查核作業；整體而言，今年度各計畫書件品質均較以往提升，主要缺失分別為資料未在時間內繳交、預定工作進度未於期限內完成及書面資料有誤等，除書面資料有誤要求計畫當場修正外，其餘皆要求提出證明及說明，並列入加強查核。 民眾滿意度問卷調查方面，本年度共取得378份有效問卷，依問卷結果顯示，民眾對於污染來源為縣內工廠或六輕排放；針對汽柴油車、露天燃燒、餐飲油煙及環保祭祀等管制；推動低污染車輛；工業區鍋爐改用天然氣等有高度認同感，比例超過50%；反之，針對空氣品質惡化應變作為、汽柴油車汰換補助、離島工業區管制、河川揚塵防制、營建工地道路認養作業、微型感測器佈建完整度及空氣品質改善等認同感度較低，比例約30-50%之間。 研擬修訂雲林縣空氣污染防制計畫方面，依據107年8月1日修正公布空氣污染防制法及109年1月空氣污染防制方案草案內容擬定雲林縣109-112年各項空氣污染管制策略，冀望112年達成PM2.5 20μg/m3之目標。未來空氣污染防制願景為工安升級、排放減量、環境友善，因應對策為延續並強化各項管制措施，共計14類管制對象、35項管制對策。

The main purpose of this project is to understand the current situation of air quality and the causes of pollution in Yunlin County, review the effectiveness and direction of the annual air pollution implementation plan, check the effectiveness of pollutant reduction to achieve the goal of improving air quality, work with Environmental Protection Administration to promote air pollution control planning, develop air quality improvement direction, plan short-, medium-, and long-term control objectives, and provide suggestions and guidelines for Yunlin County Environmental Protection Bureau to implement air pollution control in the future. This project was implemented from April 24, 2019 to April 23, 2020. The executive summary is as follows. In terms of emission status and control, according to TEDS10.0, the total emissions of TSP, PM10 and PM2.5 for the base year 2016 of Yunlin County are 15,491 tonnes, 6,994 tonnes and 2,869 tonnes respectively. The main emission sources of TSP and PM10 are bare surface, households, agriculture, forestry, fishery and animal husbandry. The main emission sources of PM2.5 are manufacturing industry, land transportation, households, agriculture, forestry, fishery and animal husbandry. The annual emissions of SOX, NOX, NMHC and CO are 8,979 tonnes, 25,861 tonnes, 18,120 tonnes and 32,161 tonnes respectively, SOX, NOX and CO emissions are highest in manufacturing industry, and NMHC emissions are mainly in household and manufacturing industry. In terms of air quality improvement, statistics of 4 air quality monitoring stations in Yunlin County show that although the annual average concentrations of PM2.5 exceed the air quality standards (35μg/m3), they still have improved year by year. The average values of SO2 and NO2 over the years have little difference, but also show a slight decrease trend. The 8th largest value in maximum hour of O3 shows an upward trend in Douliu and Lunbei, whereas a downward trend in Mailiao and Taixi. For air quality index (AQI), the proportion of good days (AQI<100) in 2018 reaches 83.3%, which increases by 12.9% from 70.4% in 2015. The number of Red Alert days for PM2.5 is 25 station days, which is also 91 station days less than 116 station days in 2015. In terms of air quality deterioration contingency operations, the number of days of implementation of contingency is 145 days, and the main indicator pollutants are fine suspended particles. When the air quality is predicted to be poor, it should initiate the notification, investigation and return operation against poor air quality according to the regional air quality deterioration control measures defined by Yunlin County. It has totally reduced 229 tonnes of TSP, 43 tonnes of PM10, 10 tonnes of PM2.5, 17 tonnes of SOX, 4 tonnes of NOX and 23 tonnes of NMHC by investigating and dealing with major pollution sources and related pollution hot spots through various plans, while requesting all pollution sources to cooperate in reducing production and improve pollution control measures. In terms of performance management of air quality maintenance or improvement plan, the results of each plan submission are compiled on a monthly basis, and the check operations are carried out on contents of each plan implementation, progress of each evaluation target project implementation and quality of the materials submission. In general, the quality of all plans and documents in this year is higher than that in the past. The main deficiencies are that the materials are not submitted within the time limit, the scheduled work progress is not completed within the time limit and the written materials are incorrect. Except for errors in the written materials requiring the plan to be amended on the spot, the remaining deficiencies all need to be proved and explained and are included in the enhanced verification. In terms of public satisfaction questionnaire survey, a total of 378 valid questionnaires were obtained in this year. According to the results of the questionnaires, the public has a high sense of identity with regard to the pollution sources of factories or six light emissions in the county, the control of gasoline and diesel oil vehicles, open-air combustion, cooking fumes and environmental sacrifice, the promotion of low-pollution vehicles, the conversion of boilers in industrial areas to natural gas, etc., accounting for more than 50%. On the contrary, the public has a low sense of identity for air quality deterioration contingency operations, the replacement subsidy for gasoline and diesel vehicles, the control of outlying island industrial zone, the control of river dust, the road adoption operation of construction site, micro-sensor construction integrity and air quality improvement, and the proportion is about 30-50%. In terms of developing and revising Yunlin County air pollution control plan, various air pollution control strategies of Yunlin County for 2020-2023 are formulated according to the air pollution control law revised and published on August 1, 2018 and the draft air pollution control plan in January, 2020, with a view of achieving the goal of PM2.5 of 20μg/m3 by 2023. In the future, the air pollution control vision is to upgrade the work safety, reduce the emission, and engage in environmentally-friendly practices. The countermeasures are to continue and strengthen various control measures, including 14 types of control objects and 35 control measures。
