In August 2016, Korean press media released the news on the discharge of hazardous chemicals from power plant into surfaces waters of the sea in Ulsan area. The power plant used antifoaming agent which contains hazardous substance (Polydimethylsiloxane) to reduce the formation of foam for cooling system. Ministry of Maritime Affairs and Fisheries (MMAF) in Korea announced that the plant violate the law (Marine Environment Management) because Polydimethylsiloxane (PDMS) is a prohibited substance to discharge into the sea as a Noxious Liquid Substances by MARPOL 73/78. However, there is no standard to apply as a noxious liquid substance and no one knows the power plant is in the scope of Marine facilities of that law. ME (Ministry of Environment) and MOTIE (Ministry of Trade, Industry and Energy) argued it is uncertain how to discharge and there is no standards to apply. In this reason, MOTIE started feasibility study research of the regulations. This follow up study investigated how treat and discharge wastewater containing hazardous chemicals from a facility, especially, power plants and companies in shore line. The primary objective is to find a reasonable method to make standards related in discharging industrial wastewater.
