Certified Storage Tank Inspection and Testing (NDT)
in the Springfield, MO area

API 653 inspections are required for large, field-erected aboveground storage tanks (ASTs) that are constructed to the API 650 standard. In Springfield, 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 Springfield, 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.

Under the EPA’s SPCC Rule (40 CFR 112), any facility storing 1,320 gallons or more of oil in aboveground containers (≥55 gal each) and at risk of discharge into navigable waters (e.g., James River tributaries) must have a certified SPCC Plan. This plan must include regular inspections and testing of tanks, piping, valves, and containment structures.

In Missouri, ASTs are regulated by both EPA and the Missouri Department of Natural Resources (MoDNR). While MoDNR does not regulate AST operations directly, they oversee release response and cleanup if leaks occur. The Missouri Department of Agriculture handles tank registration, safety, and accuracy for petroleum ASTs, per 10 CSR 100‑4.020 and related rules.

By combining federal SPCC compliance with Missouri-specific regulations, our inspection services offer Springfield businesses a one-stop solution for aboveground tank regulatory compliance and environmental stewardship.
