本計畫於104年8月17日開始執行，工作內容包含人工監測站操作維護及校正作業、環境音量監測及陳情案件處理、監測車環境監測作業、六輕工業區周界敏感區落塵監測作業、氣象站設備維護作業、離島工業區測站功能查核及電子看板維護，本報告期間各項工作執行成果，主要如下： (1)人工測站共進行65站月定期維護工作，期間儀器採樣運作均正常，並未發生臨時故障而需額外檢修之情形。 (2)已於104年9月11日及105年3月7日完成追溯一級流量校正工作，校正結果迴歸係數R2值為0.9999，符合校正迴歸係數R2值須大於(或)等於0.995規定。 (3)於104年9月22日、104年10月7日、105年1月5日、105年3月28日、105年4月6日及105年7月5日各進行1次多點校正，校正結果均符合每一流量準確度誤差不得超過5%，且經最小平方法線性迴歸分析，迴歸係數R2值須大於(或)等於0.995之規定。 (4)每站於上、下旬採樣前與採樣後執行1次單點校正，流量準確度均符合誤差不得超過7%之規定。 (5)於104年9月1日執行計時器校正，校正結果均符合24小時誤差不超過2分鐘之規定。 (6)總懸浮微粒(TSP)部分，各測站間以虎尾衛生所站和西螺鎮公所站之平均值61 μg/m3為最高，口湖金湖國小站之平均值53 μg/m3為最低，各站監測結果均符合空氣品質標準(TSP 24小時值250 μg/m3)；落塵量部分，以104年10月份西螺鎮公所站34.60公噸/平方公里/月為最高，而104年8月份虎尾衛生所站0.20公噸/平方公里/月為最低。 (7)環境、道路交通及高鐵音量監測工作已完成148站天，監測結果均符合管制標準；歷年監測結果中，在一般環境音量部分，斗南站由於易受鄰近住戶活動影響，導致部分時段測值容易升高；在道路交通噪音部分，各站均能音量穩定，不易有高值產生。 (8)已完成12次固定式噪音站維護作業，而監測結果部分，平日日間時段容易受到上下班車流量及不定期枝葉雜草修整作業影響，而假日則多為鄰近人文公園遊客數增加及活動舉辦。 (9)機動車輛噪音檢測作業已完成35場次，共計攔查2,198輛次，針對有噪音之虞之車輛進行檢測66輛次，其中檢測合格40輛次、不合格15輛次、無法檢測11輛次。由於檢測前先經過警察篩選，因此不合格率達27%，不合格車輛平均超出管制值約5.6分貝。 (10)環境中非游離輻射電磁波量測共完成極低頻20件及高頻21件。極低頻部分，10件為校園電磁場量測，另10件為低頻落地型變壓器電磁波量測；高頻量測21件均為手機基地台。極低頻及高頻之量測結果均遠低於環保署公告之非游離輻射環境建議值。 (11)完成噪音宣導海報設計，印製噪音宣導海報500張。 (12)移動式監測車空氣品質監測部分，已完成24站天監測，各站監測結果均符合空氣品質標準。 (13)六輕工業區周界敏感區落塵監測作業已完成24個乾沉降樣品，乾沉降通量介於23.2-339 mg/m2 day。本年度監測結果自104年11月份起，因受東北季風境外傳輸及裸露地影響而造成測值偏高，除本計畫測點之監測結果外，環保署測站PM10測值亦有相同趨勢。 (14)已完成10站次離島工業區測站功能查核，查核結果全數滿意。 (15)氣象站設備維護作業已完成60站月，各站狀況大致良好且無損害情形發生，僅於104年10月尚德國小及六輕北門宿舍因設備箱受海風長時間侵襲損壞，於10月1日進行設備箱更換。 (16)已完成12次電子看板每月維護工作，播放內容更新部分，已完成169筆。

This project has been started on August 20, 2015. The project scope included operation, maintenance and calibration of equipment at manual Air Quality Monitoring Station and Meteorological Station, environmental noise monitoring, dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park, check of equipment at Air Quality Monitoring Station belonging to the Sixth Naphtha offshore industrial park check and maintenance of electronic board. The achievements of project were summarized as below: 1)65 Air Quality Monitoring Station were performed scheduled monthly maintenance. All equipment was under normal operation and no overhaul was required during the project period. 2)Flow rate calibrations were completed on 11 September 2015 and 7 March 2016. The result regression coefficient R2 was 0.9999 which comply with the standard. (R2 shall be larger or equal to 0.995) 3)Multi-point calibrations were performed on 22 September 2015, 7 October 2015, 5 January 2016, 28 March 2016, 6 April 2016 and 5 July 2016. The results were fulfill with the standard requirements including flow accuracy shall be less than 5 % difference and regression coefficient R2 shall be larger or equal to 0.995. 4)Every half of the month, one point calibrations were performed before and after sampling at each station. The flow accuracy shall be less than 7% difference. 5)The clock check was performed on 1 September 2015 and fulfilled the standard of less than 2 minutes difference. 6)For TSP monitoring, the highest (61 μg/m3) and lowest (53 μg/m3) average concentration were found at Huwei station and Siluo station. For dust monitoring, the highest concentration 34.6 kg/m2 per month was found at Siluo station in October 2015, while the lowest 0.2 kg/m2 per month was recorded at Huwei station in August 2015. 7)Ambient, highway and high speed rail noise monitoring have been performed 148 days and all results fulfilled the limit. According to historical monitoring data, in ambient noise monitoring, as Dounan station was sensitive to nearby residential activities, some intervals were found a high level of noise. In highway noise monitoring, each station were recorded a relatively steady noise level. 8)12 times maintenances were completed at fixed noise monitoring station. The sources of noise were proposed. During weekdays, the noise would be come from high flow of vehicles at peak periods and operation of machine during gardening. During weekend, the sources would be park visitors and temporary exhibitions. 9)Checking of noise level from vehicles has been performed 35 times and checked 2,198 vehicles. 66 vehicles were requested to perform further noise assessment in which 40 vehicles passed, 15 vehicles unqualified and 15 vehicles unclassified. As selection by police before further assessment, the rate of unqualified was reach 27 % and average exceed 5.6 dB of limit. 10)Ambient electromagnetic field (EMF) measurement was completed 20 pieces of extremely-low frequency and 21 pieces of high frequency. In which, 10 pieces of extremely-low frequency were performed at school area, 10 pieces of extremely-low frequency were performed at Floor type transformers, 21 pieces of high frequency was performed at phone transmitting station. All the results were within the EPA limit. 11)The noise poster design was completed and 500 posters had been printed. 12)24-day monitoring of the mobile air quality monitoring vehicle had been completed. All the results were within the EPA air quality standard. 13)dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park were completed 24 pieces of samples, ranging 23.2 -339 mg/m2 per day in concentration. From November 2016 onwards, the reason for the high value of the measurement has the northeast monsoon caused by the external transmission and bare ground. In addition to the monitoring results of the project, the EPA PM10 measurements also had the same trend. 14)Sixth Naphtha offshore industrial park monitoring station audit were completed 10 times with satisfied result. 15)Operation and maintenance of meteorological station had been completed 60 months. Each station was operating normally with no damage. The equipment boxs were broken by the erosion of sea breeze at Suntech elemetary school station and North gate hostel station on October 2015 and replacement of the equipment box was performed on 1 October 2015. 16)12 times of maintenance electronic board and 169 times of content update were recorded.
