The Act on Carbon Dioxide Storage Business, Article 67 (1) stipulates that storage business operators maintain CO2 storage facilities to ensure that they conform to the technical standards established by Order of the Ministry of Economy, Trade and Industry. Additionally, Article 86 (1) of the same Act states that CO2 pipeline transport operators maintain CO2 pipeline transport facilities in accordance with the technical standards. We enacted a Ministerial Order to Provide Technical Standards for CO2 Storage Facilities based on the Act on Carbon Dioxide Storage Business to maintain public safety and prevent the occurrence of accidents, with reference to the standards mandated by the Mine Safety Act, the Gas Business Act, and the High-Pressure Gas Safety Act.
