We are aware of the risks of ground contamination due to oil leakage from underground pipes and other oil-handling facilities in operation at our refineries, complexes, plants, and service stations. To address these risks, we have been implementing autonomous surveys of ground and groundwater pollution and undertaking purification measures where needed. In particular, when the closure or rebuilding of a facility causes changes in the character of its site, we implement proper management to prevent pollution, including the resurvey of ground pollution, in compliance with the Soil Contamination Countermeasures Law.
