SP001 Inspections for ASTs: What you need to know

If your organization operates shop-fabricated or field-erected aboveground storage tanks (ASTs), you’re likely at least somewhat aware of the Spill Prevention, Control and Countermeasure (SPCC) requirements for regular inspections of these tanks. If you have ASTs that are required to conform to these regulations, there is an article in this quarter’s edition of the PEI Journal that you should read.

Titled, Integrity Testing Shop-Fabricated Aboveground Storage Tanks, the article by Alex Ralston, POE, provides an excellent summary of the inspection requirements and procedures required by STI SP001, which is the Standard for the Inspection of Aboveground Storage Tanks.

The SP001 standard applies to portable containers, shop-fabricated tanks and field-erected tanks up a maximum shell height of 50 feet, and a maximum diameter of 30 feet. In the article, Ralston summarizes the essential elements of this standard: 

"The STI SP001 standard is not a tightness test similar to those performed on underground tanks. The standard measures construction integrity; compliance with fire codes, building codes, industry standards and OSHA standards; and the integrity of the thickness of the metal tank shell as compared to the original tank shell thickness. That last requirement is essential. The shell thickness determines the suitability of the tank for continued service – specifically, whether the tank should continue in service or be taken out of service for repair or replacement. The inspection also sets the date of the next formal inspection."

The article goes on to include a detailed summary of what a certified inspector looks for in a SP001 inspection. It’s an excellent read if this is an area of concern for your fueling operation.
