Which regulatory standards are commonly cited with ICC U3 tank tightness testing practices?

Which regulatory standards are commonly cited with ICC U3 tank tightness testing practices?

• A. ICC guidelines along with applicable EPA/State UST or tank program regulations and code references.
• B. OSHA safety standards only.
• C. NFPA fire codes only.
• D. ASME material standards only.

Answer: (A)

The key idea is that tank tightness testing practices follow ICC guidelines for the testing method, but you must comply with the regulatory framework that governs underground storage tanks. In practice, inspectors use ICC’s U3 guidelines as the standard testing approach, and then verify that the work meets the applicable environmental regulations, which are typically the federal EPA UST rules and the state UST program requirements. Jurisdictions may also require adherence to related code references from local or national building, fire, or environmental codes. This combination—ICC guidelines plus EPA/State UST regulations and any relevant code references—is what you’ll see cited in real-world practice. Other standards like OSHA addresses worker safety, NFPA codes cover broader fire protection, and ASME standards relate to design and materials, not the tightness testing procedure itself.
