本計畫係配合臺中市政府環境保護局推動特定行業別及港區倉儲業者，進行法規符合度查核作業及臺中港區揮發性有機液體儲槽清查作業，並透過紅外線影像氣體微漏偵測儀(FLIR)設備元件洩漏檢查及設備元件檢測，以落實污染管制作業。另一方面執行辦理揮發性有機物減量輔導作業及西碼頭實場生物濾床測試以達到污染減量及污染防治推動等作業，此外亦針對臺中港區船舶燃油抽測，推估臺中港區船舶污染之揮發性有機物排放量；針對西碼頭區內浮頂槽通氣孔排放之圍封測試，建置內浮頂槽建置規範，以達到針對港區污染源面之掌握及污染改善方針研擬探討。此外，今年度特針對揮發性有機物辦理管制、減量2場次講習會及召開1場次空污技術專家顧問座談會，提出本縣產業VOCs減量及管制策略建議，以落實政策推動宣傳及掌握本縣各重點產業揮發性有機物減量潛勢及減量規劃，作為未來管制策略研擬方針依據。 於99年3月1日至100年2月28日計畫執行期間，總計完成已完成18家次臺中港區揮發性有機液體儲槽清查，99年總儲存量為1,490,908公秉(估算)，清查總排放量為373.84公噸，其中高揮發性物質僅約佔8.93％，可能與近年因受經濟不景氣影響所進物料多為基礎油或潤滑油脂等低揮發性物質有關。在法規符合度查核部分，港區倉儲業者其整體法規符合度約為93.5%；特定行業法規符合度查核部分其符合度約為86%，其多屬人員在法規熟悉度不足的情形下，導致工廠違反法令規範。 今年度設備元件稽查檢測至目前已完成20廠5,000個設備元件抽測及60小時FLIR影像側錄，在抽測5,000個設備元件中僅有15個元件洩漏值超過1,000ppm，佔總檢測數0.3%，由檢測結果顯示，臺中市石化業者其設備元件並無嚴重逸散問題，皆能配合政府政策落實定期檢測工作。 本計畫主要工作項目之ㄧ，揮發性有機物減量輔導作業，至2月28日前總計完成20場次輔導評鑑作業辦理，其中已有3家工廠已完成增設防制設備之評估階段並著手規劃設置作業，本計畫之VOCs減量總量約為119.59公噸。 在西碼頭實場生物濾床測試及防制設備操作維護部分，臺中港西碼頭之全尺寸生物濾床設備在7月23日移至試驗現場，自87天起削減率可有效的提升至接近100%，而液體裝載操作的去除效率也可達到80%左右，截至運轉第188日止，現場連接之貯槽排放量已累積了5306kg，經本系統處理後削減了4609 kg的對二甲苯排放，其中包含8次對二甲苯裝載操作所造成的排放削減。 在臺中港區船舶燃油抽測部分，已於99年8月11日完成臺中港區靠岸停泊船隻3船次燃油含硫份抽測作業，本次燃油含硫量檢測值皆大於>2.0wt%，尚符合國際公約之規範要求；在臺中港99年度進出港遠洋船舶空氣污染物排放量推估結果部份，其VOCs污染排放量為125.56公噸，其中以貨櫃船的排放量佔最大的比例，其次為散裝船，再其次為乾貨貨船；；在內浮頂儲槽測試與調查部分，本計畫已於99年7月23日完成2座臺中港西碼頭區內浮頂槽通氣孔排放之圍封測試，其各平均測值為1964.58ppm與1154.03ppm，依「固定污染源揮發性有機物自廠排放係數建置之作業指引」推算為排放係數，其估算結果為0.000269kg/hr與0.000044kg/hr，其則遠低於空污費-釋壓閥污染排放計算係數(0.279kg/hr)。 有關宣導會辦理，因得力於臺中市環保局及各單位協助，順利於99年6月9日與8月31日假臺中市工業會第一教室共辦理兩場次「揮發性有機物防制減量技術宣導會」，各場次會議受邀單位出席狀況均十分踴躍，相信已達成會議辦理之預期目標。另為針對目前臺中港VOCs污染管制現況及本市揮發性有機物儲槽管制策略，特邀請專家顧問進行後續減量及管制方式探討，特於100年1月28日假臺中市政府環境保護局會議室辦理1場次「臺中市空污技術專家顧問座談會」，以研擬後續VOCs減量及污染管制策略。

This project is to check the VOCs tank on specified industry and warehousing companies in Taichung Harbor Area and use FLIR to monitor the leaking and detection equipment components to conduct pollution control. It also assists to reduce the VOCs and Biofilter test in west harbor to achieve pollution reduction and control. We conducted random test and inspection on vessel fuel to estimate and measure the VOCs volumn in Taichung Harbor Area. Inspect on floating tank leaking and build up inner floating tank spec to control on the pollution source and pollution improvement. This Project also arranged two seminars for VOCs Control and Reduction and held one symposium by inviting experts and consultants in air pollution industry to suggest and provide strategy for reducing and controlling VOCs emissions. During the executive period, 18 times of VOCs tank check have been completed. The estimate total storing is about 1,490,908 kiloliters and a total emission is 373.84 tons. Among them, the highly volatile substances are only about 8.93%. In the laws and regulation compliance aspect, 93.5% of the warehousing companies 86% of specified industry is complied with the law and regulation. For those not complied with the law and regulation, mostly it is due to they are not familiar with the law and regulation. One of the main task of this project is assist in VOCs emission reduction, there are 20 times of assistance and evaluation arrangement. 3 of the factories is completed the evaluation for purchasing necessary equipments and planning equipment installation. The VOCs emission reduction is about 119.59 tons. Regarding the testing and equipment operation on Biofilter test in west harbor area, the full size of Biofilter equipments were moved to testing area on July 23rd, 2010 and achieved 100% reduction after 87 days. The removal efficiency for liquid loading operation is about 80%. After 188 days of operation, the emissions of linked tank are sum up to 5306kg. By conduction this project/system, the Xylene emission is reduced 4609kg including reducing from Xylene loading operation. As for the promotion meeting, with the assistant from Taichung Environment Protection Bureau, there were 2 sets of promotion meeting held on June 9th and August 31st, 2010. And, on January 8th, 2011, we also invited experts and consultants to participate the meeting to discuss and confer on current situation of VOCs pollution control and VOCs storing. From the discussion, it helps to provide future strategies for VOCs volume reduction and pollution control in Taichung Harbor area
