HomeAbove Ground Fuel Tank InspectionsAbove-ground Fuel Storage Tank Inspections: Missouri

In Missouri, above-ground fuel storage tanks are typically regulated by the Missouri Department of Natural Resources (MDNR) under the Code of State Regulations (CSR) Title 10, Division 25, Chapter 9. This chapter sets out the requirements for the design, installation, operation, and maintenance of above-ground storage tanks (ASTs) that contain petroleum or other hazardous substances.

Specifically, CSR 10-25.090 requires that all regulated ASTs must be inspected at least once every year by a qualified inspector. The inspector must be certified by the Steel Tank Institute (STI) or the American Petroleum Institute (API), or have equivalent qualifications approved by MDNR. The inspection must include an examination of the tank and associated piping, as well as non-destructive testing of the tank shell and bottom.

In addition to the annual inspections, CSR 10-25.090 requires that all regulated ASTs must be maintained in a safe and operable condition at all times. This includes regular monitoring for leaks, corrosion, and other signs of damage, as well as promptly repairing or replacing any damaged components.

It’s important to note that the specific requirements for above-ground fuel storage tank inspections and maintenance in Missouri can vary depending on the type of tank and the product being stored, so it’s important to check with MDNR to ensure that you are in compliance with all applicable regulations.
