Certified Storage Tank Inspection and Testing (NDT)
in the Athens, GA area

API 653 inspections are required for large, field-erected aboveground storage tanks (ASTs) that are constructed to the API 650 standard. In Athens, these tanks are commonly used by petroleum terminals, manufacturing plants, chemical facilities, and utilities to store fuel, oil, or hazardous liquids. If your tank is over 75,000 gallons, made from welded-steel construction, has a diameter of 30 feet or more, or a height of 50 feet or more, there's a high likelihood it falls under API 653 requirements.

STI SP001 inspections are typically required for shop-fabricated aboveground storage tanks under 75,000 gallons, often found at gas stations, commercial facilities, and industrial properties. If you're storing oil or hazardous substances in Athens, you may be subject to the EPA's Spill Prevention, Control, and Countermeasure (SPCC) rules for this inspection.

The frequency depends on the tank size, contents, and regulatory classification. In general, API 653 recommends formal external inspections every 5 years and internal inspections every 10-20 years. STI SP001 inspection frequency is determined by their size, category, and risk factors. We can help determine your specific schedule.

Yes. All our inspectors hold API 653 and STI SP001 certifications and are trained in accordance with industry and regulatory standards. We are fully qualified to perform inspections anywhere in Georgia, including Athens.

Under 40 CFR 112 (SPCC Rule), facilities with an aggregate capacity of 1,320 gallons or more of oil in ASTs of 55 gallons or larger — and with a reasonable potential to discharge into navigable waters — must maintain a certified SPCC Plan, including documented tank inspections.

In Georgia, ASTs fall under the jurisdiction of the State Fire Marshal and are further regulated by the EPA when surface water (e.g. Oconee River, Middle Oconee) could be impacted. The Georgia Rules for Hazardous Waste Management (Chapter 391‑3‑11) require that all regulated ASTs be inspected by a certified inspector (STI or API), and these inspections must include tank shell, bottom, and piping assessments

We assist Athens-area facilities that operate aboveground storage tanks (ASTs) by conducting certified API 653 and STI SP001 inspections and providing documentation to support compliance with both EPA SPCC regulations and Georgia regulatory requirements.
