Measures against Ground Pollution

There are ground contamination risks at our oil refineries, complexes, plants, SS (service station) caused by oil leaks from underground pipes etc. To address the risks, we have been implementing autonomous surveys of ground and groundwater pollution and undertaking purification measures if any. In particular, when the closure or rebuilding facilities cause changes in the character of the land, we implement proper management to prevent pollution, including resurvey of ground pollution, in compliance with the Soil Contamination Countermeasures Law.

  • * In FY2018, there were no serious oil spills.
