Notifications for Class 2 High-Pressure Gas Storage and Production
KH-08 | High Pressure Gas Safety Act | Class 2 storage | Class 2 producer
When installing nitrogen or carbon dioxide tanks or production equipment. From determining whether a permit or notification applies to preparing the notification.
High-pressure gas production and storage require either a permit or a notification depending on scale. Storing 300 cubic meters or more, below the threshold for a Class 1 storage facility, requires prior notification to the prefectural governor as a Class 2 storage facility (High Pressure Gas Safety Act Article 17-2). For Class 1 gases such as nitrogen, carbon dioxide and argon, 3,000 cubic meters or more, and for other gases 1,000 cubic meters or more, is a Class 1 storage facility requiring a permit. For production, a daily processing capacity of 100 normal cubic meters or more (300 for Class 1 gases) requires a Class 1 producer permit; below that, a Class 2 producer notification is due 20 days before starting (Article 5). A notification does not remove the obligation to meet technical standards. We determine the category from the gas type, storage amount and processing capacity, and prepare and file the notification and attachments. Please also consult us if a permit is required.
