The UST must be registered with which agency before it becomes operational?

• A. DEQ
• B. EPA
• C. OSHA
• D. FDA

Answer: (A)

The key idea is that underground storage tanks must be officially registered with the state environmental regulator before they can operate. In practice, this means the state Department of Environmental Quality (or its equivalent) reviews the tank’s installation, ensures it meets spill prevention, corrosion protection, and release-detection requirements, and records it in the state registry. While the EPA sets federal rules, the day-to-day registration and permitting are administered by the state agency. Agencies like OSHA or FDA regulate occupational safety or foods and drugs, not UST registration, so they aren’t the authority for this requirement.
