Inspections

Accurate, Reliable SP001 Inspections

The U.S. Environmental Protection Agency’s rule for Spill Prevention Control and Countermeasure (SPCC) contains the STI SP001 Standard, which outlines requirements for tank integrity testing.

While API 653 applies to larger tanks, STI SP001 governs compliance in shop-built and field-erected tanks of smaller sizes. 

This includes storage tanks up to 50,000 gallons (189,271 liters), including tanks that are portable, skid-mounted, liner-equipped, double-walled, and partially buried. This standard also covers the inspection of smaller portable containers such as 55-gallon drums, intermediate bulk containers or (IBC’s), and other containers that are constructed of metal or plastic.

Inspections are required at recommended intervals to remain compliant with the code and environmental regulations.
