Tank Inspection FAQ

Your questions answered about tank inspections in the San Antonio, TX area.

Under 40 CFR 112 (SPCC Rule), facilities in San Antonio storing an aggregate of 1,320 gallons or more of oil in aboveground tanks—each container 55 gallons or greater—and with a reasonable potential for discharge into navigable waters such as the San Antonio River and its tributary creeks flowing through Bexar County must prepare and implement an SPCC Plan. That plan must include documented inspections of tanks, piping, valves, and secondary containment systems to demonstrate ongoing spill prevention.

Texas maintains one of the most layered AST regulatory frameworks in the country. Under 30 TAC Chapter 334, Subchapter F, administered by the Texas Commission on Environmental Quality (TCEQ) Petroleum Storage Tank Program, petroleum motor-fuel ASTs with capacity greater than 1,100 gallons must be registered with TCEQ and are subject to construction notification, release reporting, recordkeeping, and general operational requirements. A second layer—the Aboveground Storage Vessel Safety (ASVS) Program under 30 TAC Chapter 338, adopted in 2023—imposes safety performance standards and mandatory registration by September 1, 2027 for large ASVs (21,000 gallons or greater) at petrochemical plants, petroleum refineries, and bulk storage terminals. Because San Antonio sits within the Edwards Aquifer recharge and transition zone, TCEQ also requires a facility-specific AST Facility Plan for permanent tanks with 500 gallons or more of aggregate hydrocarbon or hazardous-substance capacity. The City of San Antonio further requires a $330 construction permit for each permanent AST storing flammable or combustible liquids under its 2024 IFC-based Fire Code amendments (effective May 1, 2025). Inspections are commonly performed under STI SP001 for shop-built tanks and API 653 for field-erected tanks, with inspection intervals governed by applicable SPCC Plan requirements and the ASVS Program standards.

Genesis Inspection Services helps San Antonio-area businesses operating aboveground storage tanks navigate this multi-layered compliance environment across Bexar County and the surrounding region. From certified API 653 and STI SP001 inspections to thorough documentation packages, we deliver the inspection records and reports your facility needs to demonstrate compliance with EPA SPCC regulations and Texas state requirements under TCEQ's Petroleum Storage Tank and ASVS programs.

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