Environmental Risk Management - Management of Soil and Groundwater

• Soil and groundwater risk management policy

During the latter half of the 1980s, soil and groundwater contamination by a chlorinated organic solvent was detected in some of our manufacturing sites. Since then, we have been implementing comprehensive measures to deal with this problem. In fiscal 1992, we prepared the Manual for Preventing Contamination of Soil and Groundwater, which we have since used as our basis for all surveys conducted and preventative actions undertaken. In fiscal 1996, we completely discontinued the use of chlorinated organic solvents and in fiscal 2000 we compiled the Guide for the Prevention and Management of Environmental Pollution to thoroughly promote preventive measures. Furthermore in fiscal 2003, in accordance with the enhancement of environmental laws and regulations, we reinforced our measures to survey and prevent contamination by volatile organic compounds (VOC) and heavy metals based on our Soil and Groundwater Risk Management Policy. Wherever contamination has been detected, we immediately implement remedial measures and hold explanatory meetings and voluntarily make an announcement about the contamination through mass media, as well as following the instructions of local authorities.
