地上儲槽若未妥善維護管理發生洩漏，除污染地面水體外，亦造成土壤或地下水之污染，環保署為全面強化管理，整合增修地上及地下儲槽污染預防管理法規，「防止貯存系統污染地下水體設施及監測設備設置管理辦法」於110年1月1日起施行，依貯存物質及規模大小，分年分階段實施環境監測與申報。 本計畫採用儲存量大者、貯存對象為汽柴油、考量環境敏感區位、納入行業別代表性廠商、非加油站地下儲槽等條件建立篩選因子，並依專家諮詢會議委員意見調整修正，篩選55處事業單位（涵蓋21類產業別）作為優先輔導對象，邀請具環境監測、腐蝕防蝕、風險職安等專長領域之學者專家成立技術輔導團，提供貯存系統相關設施污染防治及預防管理技術諮詢，協助事業單位落實貯存系統污染預防及提升自主管理。並於實地現場訪視之前，辦理3場次行前說明會並蒐集輔導需求，以達輔導作業宣導之目的。除此之外，本計畫辦理1場次成果分享交流會議（全日），邀請學者專家針對儲槽管線之維運管理、環境監測以及國內外法規相關作法、發展趨勢進行講解及實務交流。 執行成果顯示，55處事業單位中槽齡10年以上有50處，平均槽齡28年，事業單位對於腐蝕防蝕方面之問題較為關切，腐蝕發生經統計可分人為、環境、物理以及其他等因素，其中最應注意維護管理的重點仍以人為因素為主。其次為環境監測方面，事業單位已採用及預計採用之監測方式以地下水監測為主，計有22處，具設置困難或無法依法規要求設置監測設施者，由學者專家評估後提供給予替代建議。輔導過程蒐集具積極管理優良之作為案例，包括自主管理方式及巡檢內容，彙整於技術手冊，提供其他單位參考。本計畫亦針對輔導個案進行案例評析，並提出建議方案以回饋環保署未來施行貯存系統管理策略之參考。

If the above-ground storage tanks are not properly maintained and managed, leakage of the tanks will not only pollute the surface water, but also cause soil or groundwater pollution. In order to strengthen the proper management of both underground and above-ground storage tanks, the Taiwan Environmental Protection Administration (“TEPA”) has revised the “Measures for the Installation of Facilities and Monitoring Equipment for the Prevention of Groundwater Pollution Caused by Storage Systems”(“Measures”), which came into effect on January 1, 2021. The Measures request the managers of the storage tanks to conduct annual environmental monitoring and reporting relevant information to competent authority in stages, based on the types of materials being stored and capacity of the storage systems. This project applied the following selection criteria for the initial screening of sites, then considered comments from the experts within the project’s advisory committee, and selected 55 sites (covering 21 industrial sectors) as the first group of sites for receiving the consultation and advisory services offered by the project. The adopted criteria for sites selection included: those with large storage capacity, used only for gasoline and/or diesel storage, located within environmentally sensitive areas, be representative of specific types of manufacturers and sectors, and categorized as underground storage tanks other than those of gas stations. Experts from the academia and industries with expertise in the environmental monitoring, corrosion prevention, and occupational risks and safety fields were invited to join the technical advisory committee of this project, to provide technical advices on pollution prevention and preventive management of facilities with storage systems, assist involved entities in implementing pollution prevention measures in storage systems, and improve their self-management process. Before conducting the on-site visits of these sites, three briefing sessions were held for the site personnel and the technical needs of the sites were collected during these sessions. In addition, the project organized one full day of meeting for interested parties which focused on the sharing of project achievements and exchange of implementation experiences. During this meeting, experts from the academia and industries were invited to give presentations and exchange practical experience on the maintenance and operation management and environmental monitoring issues of storage systems, as well as discussed domestic and foreign laws and regulations’ practices and development trends related to the storage tanks and associated pipelines. Regarding the implementation results of this project, it was found that of the 55 sites participated in this project, 50 of them own storage tanks with over 10 years in age, and the average age for all tanks in this project is 28 years. The participating sites are most concerned with the issue of the tanks’ corrosion state and corrosion prevention. According to the statistics regarding the tanks’ corrosion, the occurrence of corrosion can be due to factors involving human, environment, and/or physical characteristics. Of these factors, and mitigation of human factors should focus on the maintenance and management measures. The second most concerned issue for the sites is the environmental monitoring of the storage systems. Twenty-two (22) of the participating sites have already or are planning to adopt monitoring measures (mostly on groundwater monitoring). The sites which have difficulty or are unable to install monitoring facilities/equipment in accordance with the legal requirements have been evaluated by the project’s experts and provided with the recommendations for alternative options. During this project’s consultation process, information related to the sites with good practice have been collected, including information on self-management procedures and contents of inspection, and compiled into a technical manual which can be referenced by other interested parties. In addition, this project has also conducted analyses on the implementation results of sites receiving consultation services, and proposed recommendations which should serve as the important input for the TEPA in developing future strategies for implementation of management measures for storage systems.
