What is the recommended inspection frequency for tanks by an authorized inspector?

• A. Inspected at least every 20 years or at the quarter corrosion rate of the bottom whichever is less
• B. Inspected at least every 5 years or at the quarter corrosion rate of the bottom whichever is less
• C. Inspected at least every 5 years or at the quarter corrosion rate of the shell whichever is less
• D. Inspected at least every 20 years or at the quarter corrosion rate of the shell whichever is less

Answer: (C)

The recommended inspection frequency for tanks by an authorized inspector focuses on ensuring the integrity of the tank structure over time. In this context, inspecting tanks at least every five years, or at the quarter corrosion rate of the shell, whichever is less, aligns with the goal of identifying any potential corrosion or structural issues before they can lead to significant problems. The tank shell is particularly critical because it directly impacts the containment and stability of the tank. Corrosion rates can vary depending on several factors, including environmental conditions and the materials being stored. By using the quarter corrosion rate specifically for the shell, the inspection schedule can be accurately tailored to the actual condition of the tank rather than adhering to a generic timeline. This approach ensures that inspections are frequent enough to catch potential issues early while being flexible enough to account for varying corrosion rates that may indicate a need for more immediate inspection. The combination of these two factors enhances the safety and reliability of aboveground storage tanks. Thus, the selection reflects best practices in the industry for maintaining safe and compliant storage facilities.
