Emission Data of Production Facilities (Fiscal 2003)

The following is the data on exhaust gas and wastewater emissions from all works and plants of Kobe Steel. The tables show numerical targets and actual emissions of exhaust gases (NOx, dust and dioxins) and major elements of wastewater from facilities such as chemical oxygen demand (COD) or biochemical oxygen demand (BOD), suspended solids (SS), oil and dioxins.

Emission data is included for manufacturers 100% owned by Kobe Steel and operating only within Kobe Steel's facilities.

Air Quality Data

*	Numerical targets are based on the Air Pollution Control Law, prefectural government ordinances, and the Law Concerning Special Measures against Dioxins.
*	Unit: ppm for NOx, mg/Nm³ for dust, and ng-TEQ/ Nm³ for dioxins
*	Numerical targets are set separately for each facility.
*	The following substances can be excluded from the tables because their emissions do not reach the quantitation limit or are less than the numerical targets: SOx, cadmium, chlorine, hydrogen chloride, fluorine, hydrogen fluoride and silicon fluoride, lead, benzene, trichloroethylene, dioxin.

Water Quality Data

*	Numerical targets are based on the Water Pollution Control Law, prefectural government ordinances, the Law Concerning Special Measures against Dioxins, the Sewage Water Law and municipal government ordinances concerning sewage water.
*	Unit: mg/l (pg-TEQ/l for dioxins)
*	ND (Non-dimension): less than the quantitation limit
*	The following substances are excluded from the tables because their emissions do not reach the quantitation limit or are less than the numerical targets: pH, BOD, total nitrogen, total phosphorous, phenols, total chromium, soluble iron, soluble manganese, fluorine, copper, zinc, cadmium, total cyanide, organophosphorus compounds, lead, hexavalent chromium, arsenic, total mercury, alkyl mercury, PCB, trichloroethylene, tetrachloroethylene, dichloromethane, carbon tetrachloride, 1,2-dichloroethane, 1,1-dichloroethylene, cis-1,2-dichloroethylene, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1,3-dichloropropene, thiram, simazine, thiobencarb, benzene, selenium
