高雄市前鎮區於109年9月於原住民故事館旁發現高濃度乙烯氣體，針對該應變場址進行高解析度調查及緊急應變措施等作業；此外對其他場址監督並落實滾動管理機制等，高雄市政府環境保護局遂委由捷博科技公司辦理「高雄乙烯事件緊急應變暨周邊場址監督管理計畫」(以下稱本計畫)。 本計畫對前鎮區及苓雅區內4處場址，進行分級分區管制，轄內列管場址進度亦大致符合(詳第五章)；另針對應變場址進行細密調查，確實掌握主要污染熱區與深度(詳3.4節)，含氯污染鑑識顯示，本場址主要污染來源為E-02(E01304)；本場址污染物之化學圖譜指紋，與氯乙烯工廠化學指紋特徵相符(詳3.7節)。 本計畫緊急應變策略為「高濃度區回收」及地下水「污染邊界處攔阻」(4.3節)。「高濃度區回收」作業於本計畫已回收高濃度純相5,345噸；「污染邊界處攔阻」則於高通量處設置地下水循環系統搭配藥劑添加及地下水成效監測，計劃期間關切污染物去除率達99 %以上(4.4節及4.5節)，綜合污染通量評估結果，本場址污染通量已降低並減少污染向場外擴散。 本計畫以環保署健康風險評估系統進行第一層次風險模擬，已達可接受致癌及非致癌風險(3.6節)。此外於應變場址北側，設置24小時連續氣體偵測器，以掌控周界環境可燃氣體濃度(4.6節)。

Qianzhen District, Kaohsiung City found high-concentration ethylene gas next to the Aboriginal Story Hall in September 2020, and conducted high-resolution investigations and emergency response measures for the emergency site; in addition, it monitored other sites and implemented a rolling management mechanism etc., the Environmental Protection Bureau of the Kaohsiung City Government commissioned Jetpro Technology to handle the "Kaohsiung Ethylene Incident Emergency Response and Surrounding Site Supervision and Management Plan" (hereinafter referred to as this plan). In this project, 4 sites in Qianzhen District and Lingya District will be controlled by grade and zoning, and the progress of the management sites within the jurisdiction is generally in line with (see Chapter 5 for details). The main pollution hot spots and depths (see Section 3.4 for details), the identification of chlorine-containing pollution shows that the main pollution source of this site is E-02 (E01304); Section 3.7). The emergency response strategies of this project are "recovery at high concentration areas" and groundwater "containment at polluted boundaries" (section 4.3). "High-concentration area recovery" operation has recovered 5,345 ton of high-concentration pure phase in this project; "contamination boundary block" is to set up a groundwater circulation system at high-flux areas with chemical addition and groundwater effectiveness monitoring, and concern about pollutant removal during the project. The rate of pollution is more than 99% (sections 4.4 and 4.5). Based on the results of the assessment of pollution flux, the pollution flux of this site has been reduced and the spread of pollution to the outside of the site has been reduced. This project uses the EPA health risk assessment system to conduct the first-level risk simulation, and has reached acceptable carcinogenic and non-carcinogenic risks (section 3.6). In addition, on the north side of the strain site, a 24-hour continuous gas detector is set up to control the flammable gas concentration in the surrounding environment (section 4.6).
