Two NI 356 underground storage tanks in the process of being installed

An underground storage tank (UST) is defined as a tank, and any underground piping connected to the tank, that has at least 10% of its combined volume underground. The department's Missouri Underground Storage Tanks database contains a summary of Missouri UST data maintained by the department. This information provides agencies, the public, consultants, regulated facilities and tank owners as a useful look at the UST registration information and other data currently on file with the department.
