依據第一年度擬定之污染預防管理與監測機制，推動光電業「前端製程化學品管理」與「末端廢水水質監測機制」的示範計畫，前者係要求事業定期申報指定製程化學品之使用量；後者則要求事業進行放流水銦、鎵、鉬、總毒性有機物和生物急毒性之檢測分析。此外，本年完成增訂「水污染防治法事業分類及定義」之「光電材料及元件製造業」業別，並研訂該業別之管制項目與限值，以強化光電材料及元件製造業放流水管制成效，創造經濟與環境保護雙贏的利基。 國內諸多事業具氨氮污染潛勢，依現有調查數據綜合評估，顯示水污染管制事業與污水下水道系統氨氮排放總量約為71,644 kg/day (總排放水量乘以平均濃度)，最大貢獻來源為科學工業園區專用下水道系統，佔所有氨氮污染總量的19.5%，其次為石油化學業和畜牧業；部分相關產、公 (協) 會和目的事業主管機關已著手進行含氮水質調查評估，仍需就整體具氨氮污染排出潛勢之業別進行水質調查及評估，以通盤規劃及管理。 本計畫推動光電業放流水標準修訂及相關行政管制事宜，並前往韓國考察放流水生物急毒性之管制方式，另針對石油化學業放流水特性，規劃將揮發性有機物納入放流水標準管制，並加以評析特定業別或項目的管制方式或限值之合理性 (如養牛業之COD標準)。

According to the pollution prevention and monitoring mechanisms drafted in 2009, the Environmental Protection Agency (EPA) promotes the demonstration plan that includes detailed chemicals disclosure in the manufacturing process (upstream) and wastewater monitoring (downstream) in the optoelectronic industry and Science Park. For the chemicals disclosure, the manufacturers are asked to regularly declare the raw materials used by the industries. For the wastewater monitoring, the manufacturers are asked to check for the indium, gallium, molybdenum, total toxic organic (TTO), and acute toxicity in the effluent. Further, the plan suggests adding optoelectronic material and element manufacturing industry to the Water Pollution Control Act Industry Classifications and Definitions and drawing up the regulated items and standards. Then, the EPA can control the effluent discharged from optoelectronic material and element manufacturing industry. There are many industries that discharge ammonia-nitrogen in their wastewater. The investigation estimated that total ammonia-nitrogen discharged from industries was 71,644 kg/day. The largest contributor was sewage system in Science Park, and its load was estimated to be 19.5% of the total ammonia-nitrogen. Further, both petrochemical industry and animal husbandry also have high pollution potential. Some industry associations and organizations have started the investigation and analysis of nitrogen-containing wastewater. By means of accumulating more wastewater data, it will promote the set up of ammonia-nitrogen effluent standard. The plan has revised the Effluent Standard of optoelectronic material and element manufacturing industry and gathered information on the regulations of the effluent acute toxicity in Korea. Further, based on the wastewater characteristics in petrochemical industry, the plan has drafted the volatile organic compound categories and their standards. Furthermore, the plan also investigates the appropriateness of regulations and standards for specific industry or items (such as the COD standard of dairy farm wastewater).
