Based on the lessons learned from the damage to refineries caused by the Great East Japan Earthquake and the seriousness of gasoline shortages, the government has provided subsidies to carry out earthquake-resistant projects in various places, but the largest class in which multiple refineries are expected. According to a survey by the Board of Audit, we were taking measures based on a lower standard than the earthquake in Japan.
In the Great East Japan Earthquake, refineries were damaged and shipments of petroleum products such as gasoline stopped, resulting in a shortage of fuel for emergency power sources for local government offices and emergency vehicles such as fire departments.
For this reason, the national government is subsidizing oil companies to take measures against earthquakes and tsunamis at refineries in order to provide a stable supply of oil in the event of a large-scale disaster such as a huge Nankai Trough earthquake or an earthquake directly beneath the capital. I will.
The Board of Audit examined 20 refineries of 10 subsidized oil companies and found that 12 refineries were taking measures with lower standards than the largest possible earthquake. I did.
It means that the latest seismic data published by the national study group was not used, or if there were multiple data, the one with the smaller value was adopted.
The Board of Audit sought guidance from oil companies, including adopting the latest data and the strictest assumptions, saying that the Agency for Natural Resources and Energy, which has jurisdiction over the business, did not clearly indicate what standards to use. It was.
The Agency for Natural Resources and Energy says, "I would like to receive an indication and consider how to respond."
