本計畫於110年3月3日開始執行，工作內容包含監測設施設置及連線法規符合度查核、辦理連續自動監測設施連線數據檢核及現場查核作業、辦理連續自動監測設施系統功能查核及監督檢測作業、建置CWMS整合平台、維護雲林縣CWMS管理平台正常運作、行動監控大排廢水及建置資料庫主機伺服器並提供局端專有網際網路線路，本報告期間各項工作執行成果，主要如下： (1)完成20家次CWMS列管對象之法規符合度查核作業，查核意見均提請廠方改善，並針對第一次查核結果篩選複查對象共計10家次，法規符合度常見缺失包含：校正工作未落實導致監測數據準確性差異過大、取樣設備水樣代表性不佳、中控端電腦設定不完善、攝錄影監視設施之監視影像未保存90日以上、未依變更及汰換程序相關規定辦理等。 (2)完成1場次廢(污)水自動監測(視)設施法規說明會，實際參加人數為52人已符合契約及招標文件之規定。 (3)110年列管對象之異常管制圖顯示異常狀況主要為出現定值、超限值及0值之異常監測值，而對於0值之異常值常以正常值或超限值之狀態碼上傳至環保局，此將影響監測記錄值及有效率之真實性 (4)異常管制圖結果顯示共有四家事業單位於110年上半年度及下半年度皆有異常情形，分別為(a)斗六工業區(P4601715)：設備商為冠辰數位，異常項目為COD、EC、Temp；(b)鴻和皮革(P5104671)：設備商為大同環保，異常項目為SS、COD、Temp；(c)育生畜牧場(P6500097)：設備商為環測環工，異常項目為pH、EC、Temp；(d)億山畜牧場(5900084)：設備商為環測環工，異常項目為pH、Temp。 (5)完成12廠次之CWMS列管對象之提送措施說明書審查作業。 (6)完成5場次相對準確度測試查核(RATA)定檢監督作業，分別為福懋興業(P4600987)、台塑麥寮一廠(P5802421)、雲林斗六水資(P46A2877)、台化麥寮廠(P5801773)及雲林科技工業區(大北勢區)(P4606345)，檢測結果均符合水污染防治措施及檢測申報管理辦法附件三之相對誤差測試查核規定。 (7)完成5場次CWMS數據平行比對，分別為台塑勝高麥寮矽晶圓廠(P5801871)、南亞塑膠麥寮總廠(P5801513)、台化海豐廠(P5802092)、斗六工業區(P4601715)及長春麥寮廠(P5805271)；其中斗六工業區(P4601715)之比對結果整體訊號分析與環保局訊號起伏狀態落差甚大，視為應持續追蹤及加強稽查之對象；其餘事業單位部分測項偶有較大差值產生，推測可能與訊號傳輸延遲或隔離器雜訊等因素有關 (8)CWMS整合平台之系統已建置完成。 (9)完成六組行動水資源監測站設置作業，並維持24小時監測。 (10)測點1(斗工)於7月7日16時13分出現pH高值警訊(pH=9.09)，本計畫即時橫向通報稽查計畫前往巡查，經查獲上游端某水泥製品工廠利用不明管線將廢污水排出，將由環保局依法告發。 (11)測點1(斗工)於8月16日19時50分出現pH高值警訊(pH=9.68)，同時導電度亦出現異常高值(EC=6,835.68 μmho/cm)，本計畫即時橫向通報稽查計畫前往巡查，經查獲上游端某食品工廠利用不明管線將未經處理之強鹼廢污水排出至工業區雨水下水道，將由環保局依法告發。

The Project starts from 3 March 2021. The tasks include setting up monitoring systems and checking the connection status conforming to the law, checking CEMS connection figures and onsite inspection, inspecting and supervising the function of Continuous Emission Monitoring Systems, setting up a CWMS integrating platform, maintaining the operation of the CWMS management platform of Yunlin County, active monitoring of escape channels, setting up the server for database and provide special internet route for the bureau. The results of this project are as the following: (1) 20 CWMS surveilled companies were checked as to their legality. The reviews were sent to the companies for them to improve and 10 companies were chosen for the second check. The common failures for the legality were: big accuracy difference of the monitoring figures due to the incomplete calibration; water samples from the sampling facility were not representative; improper setting of the central computer; images of CCTV were not preserved more than 90 days; replacing procedure was not carried out according to the regulations. (2) A meeting for law and acts on waste water automatic monitoring system was completed with 52 people attended, which conforms the prescription in the contract. (3) The monitoring charts of the surveilled companies in 2021 showed that the abnormalities were mainly fixed values, over-limit value and 0. And for the value 0, it is often uploaded to the EPB as the status codes of normal or over-limit and this would affect the authenticity of monitoring records and effectiveness rates. (4) The monitoring charts showed abnormalities of 4 companies in season 1 ＆ 2 and 3＆4. They were (a) Douliou Industrial Park (P4601715) with the system supplier Kwanchen Digital. The abnormal items were COD, EC, Temp; (b) Honghe Leather (P5104671) with the system supplier Datong Environmental Protection. The abnormal items were SS, COD, Temp (c) Yushen Livestock Farm (P6500097) with the system supplier Hwenche Environmental Technology. The abnormal items were pH, EC, Temp; (d) Ishan Livestock Farm (5900084) with the system supplier Hwenche Environmental Technology. The abnormal items were pH, Temp. (5) 12 reviews of the measures proposals of CWMS surveilled companies were completed. (6) 5 RATA regular inspections were done. They were Formosa Taffeta (P4600987), Mailiao Factory I of Formosa Plastics (P5802421), Water Reclamation Center, Doulio City, Yunlin County (P46A2877), Mailiao Factory of Formosa Chemicals (P5801773) and Yunlin Technology Industrial Park (Dabeishi District) (P4606345). The inspection results all conformed to the regulations for Relative Accuracy Test Audit in Annex 3 of Water Pollution Control Measures and Test Reporting Management Regulations. (7) 5 parallel comparation of CWMS figures were carried out. They were Silicon Wafer Factory of Formosa Sumco Technology in Mailiao (P5801871), Mailiao Factory of Nanya Plastics (P5801513), Haifeng Factory of Formosa Chemicals (P5802092), Doulio Industrial Park (P4601715), Mailiao Factory of Changchun Group (P5805271). Among them, the result of Doulio Industrial Park showed big difference in terms of the overall signal analysis to the one of EPB regarding the fluctuation pattern and there should be follow-up and more inspections afterwards. The figures of the other business occasionally showed apparent deviation, which was assumed to be related to the delay of signal transmission or noise of the isolator. (8) The integrating platform of CWMS was set up. (9) 6 mobile water resource monitoring stations were set up and 24 hour monitoring. (10) Measuring point 1 (Doulio Industrial Park) showed warning of high pH value (pH=9.09) on 16:13 7 July. We immediately informed the inspection project to go to check. It was found that in the upstream, one cement products factory had discharged waste water through unidentified pipes and this was reported to the EPB by the law. (11) Measuring point 1 (Doulio Industrial Park) showed warning of high pH value (pH=9.68) on 19:50 16 August. Meanwhile, the Electrical conductivity also showed abnormally high value (EC=6,835.68 μmho/cm). We immediately informed the inspection project to go to check. It was found that in the upstream, one food factory had discharged unprocessed strong alkaline waste water through unidentified pipes to the drainage in the Industrial Park and this was reported to the EPB by the law.
