Certified Storage Tank Inspection and Testing (NDT)
in the St. Joseph, MO area

API 653 inspections are required for large, field-erected aboveground storage tanks (ASTs) that are constructed to the API 650 standard. In St. Joseph, 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 St. Joseph, 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 40 CFR 112 (SPCC rule), any facility in St. Joseph that stores 1,320 gallons or more of oil in aboveground containers (≥ 55 gal each) and is likely to discharge into navigable waters—such as the Missouri River, which flows adjacent to the city—must implement a certified SPCC Plan. This includes documented inspections of tanks, valves, piping, secondary containment, and drainage systems.

The Missouri Department of Agriculture oversees operational regulation and inspection guidance for ASTs in Missouri. St. Joseph municipal code enforces Missouri’s water pollution statute (RSMo 644.051) where illicit discharges into local waters are prohibited. This is particularly important near the Missouri River, making secondary containment and stormwater best management practices essential.

By aligning federal SPCC standards with Missouri’s AST regulations and St. Joseph’s stormwater ordinances, our inspection services help with compliance—covering everything from structural inspections to regulatory documentation.
