本計畫執行主軸分6大類，包括研擬公有污染土地環境再生計畫、規劃特定區域監控技術運用與工具、試辦具污染潛勢場址空氣品質監測、特定事業廢棄物資源化情形調查、協助棄置案件管考與追蹤，以及廢棄物棄置案件管理系統(Waste Dumping Management System, WDMS)維運工作與其他行政支援。 在研擬公有污染土地環境再生計畫，今年已完成公有污染土地5處場址之經濟成本及經濟效益之量化評估，公有污染土地經清理整治恢復原有價值後，初始投入成本可被租金攤還的評估年期至少需要30年，回收期較長。本計畫將不可量化效益、社會成本及社會效益納入考量，例如將場址設定為太陽能光電產業綠能示範模場用地，提高租金回收以縮短回收期至20年。 在規劃特定區域監控技術運用與工具部分，今年針對環保署管轄之焚化廠和掩埋場，規劃於全國焚化廠及掩埋場之入口處設置閉路電視錄影監視系統(CCTV)，搭配車牌辨識系統，並串接磅秤設備資訊，透過入口影像之辨識連接磅秤讀數，直接紀錄垃圾進場重量，提升行政效能。 在試辦具污染潛勢場址空氣品質監測部分，今年建立具空氣污染潛勢棄置場址之篩選方式、前置場勘以及空氣品質監測設計，並且試辦一處場址之空氣品質監測(WDMS案件編號382)，其場址棄置廢棄物為污泥，優先關注懸浮微粒測值，監測結果屬空氣品質良好，該棄置場址對於人體健康無顯著影響，一般民眾及敏感性族群也不會造成不適。 在特定事業廢棄物資源化調查，今年調查太陽能產業晶圓所產生之廢切削油(液)之處理情形，以及持續辦理廢鋁渣(鋁集塵灰)之資源化改善。在調查廢切削油(液)處理現況，完成申報資料統計，以及實地訪查其產源、處理/再利用機構共計10家，現況廢切削油(液)產出量較過去已減少許多，處理量能足夠，整體並無去化問題，建議廢切削油(液)回收處理，可朝向矽和碳化矽回收再利用，尤其矽資源可推動經濟循環。在廢鋁渣(鋁集塵灰)之資源化改善，今年輔導3家產源減少廢鋁渣(鋁集塵灰)貯存量，以及協助2家磚窯廠進行鋁渣灰處理之試驗，試驗結果鋁渣灰需經過前處理，以氧化鋁形式進料製磚。今年亦彙整收受鋁渣灰處理/再利用機構之允收標準以及編撰廢鋁渣(鋁集塵灰)處理/再利用稽查手冊指引，並宣導環保局加強現場稽查與管理。 在棄置案件追蹤部分，今年建立案件資料填報情形之評分機制，定期輔導環保局填報，並彙整列管案件巡查情形與案件進展，供環保署作為階段性管制成果之參考。另外，除定期進行系統例行維運工作外，更協助環保署辦理各項會議。

計畫摘要說明

The project comprises six parts, including drafting programs for the remediation of contaminated public lands, planning the use of monitoring techniques and tools in designated areas, conducting trials for monitoring the air quality of pollution potential sites, investigating the recycling status of designated industrial waste, providing assistance in the supervision, evaluation and tracking of dumping cases, maintaining and operating the Waste Dumping Management System (WDMS), as well as providing other administrative support. In drafting programs for the remediation of contaminated public lands, quantification and evaluation of economic costs and benefits have been done to five sites of the contaminated public lands. After the contaminated public lands get restored, it is estimated that it would take at least 30 years to recover the initial cost with rental income, which indicates a longer payback period. This project took into account the unmeasurable benefits, social costs and social benefits. For example, if the polluted lands are designed for solar photovoltaic green energy model sites, the payback period could be reduced to 20 years by raising rents. As for planning the use of monitoring techniques and tools, the closed-circuit television cameras are planned to be installed at the entrances of incinerators and landfill sites controlled by the Environmental Protection Administration. Together with the use of the license plate recognition system that connects the scale equipment information, the weight of the incoming garbage could be directly recorded to enhance administrative efficacy through CCTV to identify license plates and obtain the weight information. In conducting trials for monitoring the air quality of pollution potential sites, the establishment of the filter methods for air pollution potential sites, pre-site visit and the design for air quality monitoring were finished this year. A trial implementation on air quality monitoring (WDMS Case No. 382) was done at one site where sludge had been dumped. The particulate matter index was put on high priority in this trial implementation. The results showed that the air quality is good. The dumping site poses no significant impact to human health and would not cause discomfort to the general public and sensitive groups. As for investigating the recycling status of designated industrial waste, this project has investigated the recycling status of waste cutting oil (fluid) resulting from the solar industry wafers, and continued to improve the recycling of aluminum slag (aluminum dust). In the investigation of the recycling status of waste cutting oil (fluid), reporting data have been collected. This project also conducted on-site survey of 10 treatment/ recycling facilities. The current production of waste cutting oil (fluid) has been reduced compared to the past. With sufficient treatment capacity, there is no difficulty in tackling such waste. It is suggested that the recycling of cutting oil (fluid) could further develop toward the recycling of silicon and silicon carbide (SiC) to encourage the circular economy of silicon resources. As for improving the recycling of aluminum slag (aluminum dust), this project has helped three source enterprises reduce the storage in the volume of aluminum slag (aluminum dust), and provided assistance to two brick kilns to conduct experimental treatment of aluminum slag and dust. The results showed that pre-processing is necessary to transform the aluminum slag and dust into aluminum oxide to perform brick manufacturing. In addition, this project also compiled the information of acceptance standards for aluminum slag and dust from receiving treatment/ recycling facilities, and edited an inspection manual guidance for the treatment/ recycling of aluminum slag (aluminum dust), as well as urging the environmental protection bureaus to reinforce on-site inspection and management. Scoring system for filling in information was established this year for the purpose of tracking illegal dumping cases. Local environmental protection bureaus shall fill in information in this respect on a regular basis under the help of this project. Inspection status and progress of the controlled cases were compiled as a short-term outcome for the reference of the Environmental Protection Administration. Apart from the regular maintenance of WDMS, this project also assisted the Environmental Protection Administration in holding all kinds of meetings.
