針對雲林縣境內畜牧業進行調查，包含畜牧業分布位置、貢獻污染百分比、關鍵影響測站相對位置等，調查對象以屬事業定義，且領有畜牧場登記證或畜禽飼養登記證為主的畜牧業，主要調查在北港溪流域、新虎尾溪流域、濁水溪流域、大義崙大排、八角亭大排、施厝寮大排、有才寮大排、馬公厝大排及牛挑灣大排等區域之畜牧業的位置分布，及水質關鍵測站包含土庫大橋、雲嘉大橋、觀光大橋、海豐橋、豐橋等5處的相對位置。 後續依照雲林縣畜牧業分布及污染負荷情形，提出沼液沼渣農地肥分使用輔導之畜牧場建議名單(98家)，前往進行畜牧場現場設備法規符合度調查作業，以了解畜牧場廢(污)水處理設施現況、厭氧發酵天數、沼氣收集運用情形、可施灌沼液沼渣之農地情形，及與畜牧業者宣導沼液沼渣農地肥分使用申請條件、方式及相關水污染法令。 為提升畜牧業者與農民對於申請沼液沼渣農地肥分使用計畫之意願，已印製2,000份指引手冊，於現場輔導及宣導說明會上發放，本計畫截至11月30日已辦理10場次宣導說明會，參與人數達894人，共回收222份意願調查表，有申請意願且場內設備有厭氧池及紅泥沼氣袋飽滿之場家共38場，其中29場有自有農地，後續亦針對此29場進行現場輔導，已協助12場提出申請。另於4月26日已辦理一場次之示範場實地觀摩會，參與人數達52人(不含環保局及工作人員)。 同時為輔導雲林縣境內大型畜牧場申請沼液沼渣農地肥分使用計畫，並查察中小型畜牧場是否仍有飼養情形，施行稽查管制作業，對於雲林縣境內飼養豬隻3,000頭以下或屢遭民眾陳情之畜牧場，進行廢水處理設施操作及廢水排放情形等一般性稽查作業，截至11月30日已稽查528場家，其中19場為全場暫時停工，18場無人在場，且稽查之場家均無發現繞流之情形；雲林縣境內飼養豬隻3,000頭以上、屢遭民眾陳情或無意願申請沼液沼渣作為農地肥分使用之畜牧場，則進行放流水採樣作業，每場至少辦理1次採樣作業，截至11月30日共有171場次已採樣，且均已出具檢測報告，有68家不合格，不合格率達39.8 %，BOD及SS均不合格者有20家，僅BOD不合格者有11家，僅SS不合格者有37家，且於採樣時有23場表明有意願申請沼液沼渣作為農地肥分使用，後續均已前往輔導，有6場由本計畫協助提出申請。 在105年度8場示範場成效追蹤方面，已完成8場地下水豐、枯水期及土壤監測，土壤重金屬銅與鋅測值均低於土壤污染監測標準；地下水氨氮測值多數小於停灌標準，另雖有3筆數據超過，經複測或細部檢視施灌紀錄，並非為施灌作業所導致，整體而言，8場沼液沼渣農地肥分使用計畫案在施灌期間對環境應無負面影響。 在協助提出沼液沼渣農地肥分使用計畫申請方面，截至11月30日已有59場進行沼液沼渣之檢測、土壤及地下水檢測，進行預計施灌沼液沼渣之農地土壤檢測前儀器分析作業177點次，並均已完成申請書之撰寫及提送，截至12月31日已審核通過54場，合計105~106年通過之場家數為68場，施灌農地面積為280.390996公頃，施灌量208,202.39(公噸/年)，計算BOD總削減量約為2,281.67(公斤/天)，NH3-N之削減量為219.61 (公斤/天)，且一年約可省下701,836元之水污費，換算可減少使用約12,558包的台肥5號，大約新台幣4,144,140元。 另依據行政院農業委員會105年度統計年報資料顯示，雲林縣種植作物面積約119,452.07公頃，種植最多之作物以稻米為大宗，種植面積達44,436.06公頃(佔37.2 %)，根莖、葉菜類種植面積合計約佔23.8 %，狼尾草種植面積約323.54公頃，稻米及根莖菜類以每頭豬每天產生20公升之廢水來換算；狼尾草則以每頭牛每天產生80公升之廢水進行計算，其雲林縣目前耕地面積均足以容納養豬及牛每天所產生之沼液沼渣，惟後續仍需繼續推廣，建立農民信心，以提升農民意願。 在彙整106年度河川污染整治(含流域管理)計畫相關成果方面，已於6月28日及10月24日各召開一次跨局處工作檢討會議，並於12月25日配合機關出席相關考核會議，統整106年1-10月工項，考核自評分約為76.504分。

The project aims at surveying animal husbandry in Yunlin County. The content of survey includes the distribution of animal husbandry, the percentage of pollution contributed, the relative locations of key survey stations, and so on. The survey objects are focused on the animal husbandry business which owners have registration certificates for breeding livestock or poultry, and the survey areas are mainly at Beigang, Xinhuwei, Zhuoshui River basin, and Dayilun, Bajiaoting, Shicuoliao, Youcailiao, Magongcuo, as well as Niutiaowan Drain. The survey areas also include Tuku, Yunjia, Guanguang, Haifeng and Feng Bridge. Based on the distribution of animal husbandry and pollution load condition, the project comes up with a suggestion list of 98 livestock farms which could be counseled for using biogas fermentation residue as fertilizer. Project developers visit those livestock farms to check whether the facilities are qualified, to understand current conditions of waste water treatment facilities in farms, days of anaerobic fermentation, conditions of biogas collection and utilization, farm lands which can be used for biogas fermentation residue irrigation, and also to introduce farm owners the application procedures for biogas fermentation residue as fertilizer, as well as related water pollution regulation. In order to raise farm owners’ interest in using biogas fermentation residue as fertilizer, project developers have printed 2,000 guidance brochures and hand them out during on-site counseling and promotional meetings. It is estimated that 10 promotional meetings will be held in the duration of the project, and by 30 November there were already 8 meetings held, 894 participants joining, and 222 willingness questionnaires collected. There were 38 farm owners who already have anaerobic pools and biogas bags on their farms showing interest in applying for the project. Among the farm lands of these owners, there were 29 self-owned farm lands. Project developers also counsel these 29 farm lands on site. There were a demonstrative observation tour held on 26 April with 52 participants, excluding staffs from the Environmental Protection Bureau and other staff members. Meanwhile, in order to counsel large livestock farms in Yunlin County to use biogas fermentation residue as fertilizer, and to check whether some small to medium farms are still operating, project developers conduct waste water facilities operation and waste water discharge inspection on farms in which less than 3,000 pigs are fed and on those which often receive people’s statements. The inspected amount of farms reached 528 by 30 November. nineteen of them were temporarily suspended, and eighteen of them were visited with no owners around. None of the inspected farms were inspected with bypass discharge. For the farms in which more than 3,000 pigs are fed, those which often receive people’s statements or unwilling to use biogas fermentation residue as fertilizer, water sampling is conducted. 171 farms were inspected by 30 November, and among the 171 effective reports, 68 of them are under qualified. The under-qualification rate is 39.8%. There are 20 farms which fail at qualifying BOD and SS, 11 farms fail at reaching BOD standard, and 37 farms fail at reaching SS standard. During the water sampling process, there were 23 farms which owners are willing to use biogas fermentation residue as fertilizer, with project developers conducting counseling afterwards. So far, six of them are assisted by the project to apply for the biogas fermentation fertilizer. As to 8 performance tracking in demonstrative areas in year 2016, 8 dry and wet season groundwater table monitoring and soil monitoring were accomplished. The monitoring results will be compared and contrasted with the background value first proposed in year 2016 in order to understand the influence to groundwater system and soil near farm lands irrigated with biogas fermentation residue. As to assisting the application of using biogas fermentation residue as fertilizer, there were 59 farm lands conducted with biogas fermentation residue check, soil and groundwater check by 30 November. 177 pre-instrumental analysis for farm lands which will be irrigate with biogas fermentation residue were also finished by the same date mentioned before. 59 application documents are written and submitted. By December 31, 54 applications were approved. In total, there were 68 applications that were approved in 2016 and 2017. These 68 businesses’ irrigation area was 280.390996 hectares and their irrigation volume were 208,202.39 tonnes / year. It is estimated that each day BOD can be reduced by about 2,281.67 kilograms, and NH3-N can be reduced by about 219.61 kilograms. Each year water pollution control fees can be reduced by NTD 701,836. The use of No.5 Taiwan Fertilizer can be reduced by about 12,558 bags, which cost about NTD4,144,140. According to 2016 Statistical Yearbook of the Council of Agriculture, the planted area in Yunlin County was about 119,452.07 hectares. Rice was the most widespread crop. The planted area of rice was 44,436.06 hectares (37.2%). Root and tuber crops and leaf vegetables together accounted for 23.8 % of the total planted area. The planted area of Pennisetum purpureum Schumach was 323.54 hectares. Assuming each pig generates 20 litres of wastewater each day, and each cattle generates 80 litres of wastewater each day, the planted area in Yunlin County was large enough to use all the biogas residue and biogas slurry generated from pig farms and cattle farms. Further promotion is needed to increase farmers’ willingness to adopt this method. As to 2017 Rivers and Streams Pollution Remediation (including Watershed Management) Project, performance review meetings across units were held on June 28 and October 24. The project also participated in a related evaluation meeting on December 25. The self-evaluation score was about 76.504 for the performance between January and October, 2017.
