「97年度加強離島工業區空氣污染物整合執行計畫」自97年9月9日至98年6月8日止，計9個月，共計已完成訂定各項逸散污染源揮發性有機污染物排放量彙整與確認、106點次NMHC排放通量掌握、30廠次委員現場查核、200點次量測VOCs濃度流佈、20點次BTEX濃度分析及4場次教育訓練等五大執行目標，並配合規劃彙整及確認各項排放量（近三年前10大製程）、以FTIR或GC/MSD等儀器將有害空氣定性、掌握推估逸散性污染排放量、驗證NMHC排放量與通量觀測、掌握NMHC及CO2於廠區內的空間濃度分佈，其中在NMHC濃度檢測結果部分，發現有與二氧化碳濃度呈現相反的情況，而濃度較高之主要分布區域有廢水處理廠區、儲槽區及芳香烴類製程區，推測可能原因為揮發性有機氣體逸散，其濃度範圍可達5.5-7.9 ppm。而採樣結果廠區中NMHC平均濃度範圍在2.4 - 4.8 ppm，與96年度環保署空氣品質年報所提供之雲嘉南空品區NMHC濃度0.28 ppm高出許多，同時在FTIR分析4條測線的結果可發現周界空氣成分與該廠主要產品相似，對整體揮發性有機物的逸散管制應有改善之空間。 另外藉由六輕查核工作進度會議、四次工作檢討會及專家諮詢會議及教育訓練的辦理也確實提升對整體六輕空氣污染管制的執行績效，較具體掌握六輕全廠揮發性有機物的合理排放量，此外計畫內亦藉由委員現場查核、乙烯及丙烯等主要物種的質量平衡等作業掌握管制層面的問題，計畫內已具體彙整成管制建議，並於第五次工作檢討會時機至環保署報告其內容，相關查核成果亦將完整提供 貴局藉由適當時機向環保署等單位提出做為未來研擬管制策略或法規修訂之重要參考依據，除冀望得以持續落實現有之許可制度、稽巡查、監測及預警系統外，亦希望藉此加強污染源與排放量之掌握及建立六輕管制策略，進而有效協助提昇整體空氣品質管理之成效。

The enhancement of air pollutants control integration in coastal industrial park was conducted from September 9th, 2008 to June 8th, 2009, 9-month duration. The 5 accomplished goal included the collection and verification of volatile organic compounds (VOCs) from various emission source, 106 measurements of NMHC emission flux, 30 facilities of committee on-site investigation, 200 measurements of NMHC concentration, 20 analysis of BTEX concentration, and 4 training meetings. Additionally, the content of project contained the integration and validation of various emissions (10 major processes at the latest 3 years), qualitative determination of VOCs using FTIR or GC/MSD instrument, estimation of VOCs emission, verification of NMHC emission and flux observation, survey NMHC and CO2 spatial concentration distribution in the industrial park. The result of NMHC concentration distribution showed that it was opposite proportional to CO2 concentration distribution, and the hot spot of NMHC concentration was shown in wastewater treatment area, tanks and aromatic compounds processes. The NMHC concentration range of hotspot was 5.5–7.9 ppm. The average NMHC concentration range was 2.4-4.8 ppm in this area that was higher than 0.28 ppm in Yunlin-Chiayi-Tainan air quality basin in 2007. The FTIR analytical result of 4 measurement lines indicated that air composition was similar to major products in the factory which showed the improvement potential for the VOCs fugitive emission. Additionally, this project improved the performance of air pollution control measures and better understood the potential emission of VOCs in No.6 Naphtha cracking plant by performing the progress meeting, 4 review meetings, expert advisory and training meeting. This project also conducted the management aspect by committee on-site investigation, mass balance of major products such as ethylene and propylene. The project was specifically delivered useful command and control suggestion on 5th work review in EPA. The related result has also completely submitted to Yunlin bureau of environmental protection and EPA that should make modification on control policy development and regulations at suitable time. In addition to the existing permission system, investigation, monitoring and warning system, it should better control pollution source and emission and develop control policy of NO.6 Naphtha cracking plant, and effectively improve the managerial performance of air quality further.
