Tank Integrity Testing
Steel aboveground storage tanks (ASTs) are susceptible to degradation from internal and external corrosion and stress due to climate and settling. Various regulations, including the EPA's updated SPCC Rule (40 CFR 112), now require periodic integrity testing of storage tanks to ensure their continued reliability.
The primary tank inspection and integrity testing standards are the Steel Tank Institute (STI) SP001: Standard for the Inspection of Above Ground Tanks, and the American Petroleum Institiute (API) API 653: Tank Inspection, Repair, Alteration and Reconstruction Standard. Most tanks used in industry can be inspected without emptying or taking the tank out of service. A selection guide for determining the proper inspection standard, scope and frequency is available at the bottom of this page.
Resolve's inspectors are certified to conduct both STI SP001 and API 653 inspections. We have developed and certified many SPCC Plans, so we have the experience to select the optimum integrity test program – one that meets all legal requirements but does not involve unnecessary expense or tank downtime.
Resolve has performed tank integrity tests at DOD facilities, manufacturing plants, industrial wastewater plants, and oil terminals. AST inspectors oversee ultrasonic thickness and magnetic flux studies of tank shells and floors and conduct a thorough examination of past inspection records, manufacturing specs, foundations, supports, secondary containment, spill control, and continuous release detection methods, ancillary equipment, bonding and grounding systems, stairways, handrails, and platforms, coating, shell thickness and condition, welds, attachments, and the tank roof. Resolve prepares and certifies comprehensive reports to document each tank inspection, identify future tank testing intervals and, if necessary, provide recommended corrective actions.
