STI SP001 Inspections
Our certified inspectors perform tank inspections per the SP001 protocol and provide a certified inspection report detailing all findings and recommendations.
Inspection of aboveground storage tanks (ASTs) is critical for compliance under the planning requirements of the U.S. Environmental Protection Agency’s rule for Spill Prevention Control and Countermeasure (SPCC). In 2000, Steel Tank Institute released the first version of Standard for the Inspection of Aboveground Storage Tanks – the STI SP001 standard – which provides a means for AST owners to comply with EPA mandates. The standard, now in its fifth edition, has been updated by a consensus of tank owners, tank manufacturers and other industry leaders.
STI SP001 meets the intent of 40 CFR 112.8(c)(6) which states, "Test or inspect each aboveground container for integrity on a regular schedule and whenever you make material repairs. You must determine, in accordance with industry standards, the appropriate qualifications for personnel performing tests and inspections, the frequency and type of testing and inspections, which take into account container size, configuration, and design (such as containers that are shop-built, field-erected, skid-mounted, elevated, equipped with a liner, double-walled, or partially buried). Examples of these integrity tests include, but are not limited to: visual inspection, hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or other systems of non-destructive testing. You must keep comparison records and you must also inspect the container's supports and foundations. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. Records of inspections and tests kept under usual and customary business practices satisfy the recordkeeping requirements of this paragraph."
