Which regulation regulates underground storage tanks?

• A. UST
• B. CERCLA
• C. RCRA
• D. LUST Trust Fund

Answer: (A)

Underground storage tanks are regulated by the UST program, which directly governs their design, construction, operation, and closure. This program is part of the broader RCRA framework (Subtitle I) and is implemented through standards found in 40 CFR Part 280. It covers requirements such as leak detection, spill and overfill prevention, corrosion protection or double-walled construction, secondary containment, financial responsibility, and proper closure and corrective action. CERCLA focuses on cleanup of releases and establishing a Superfund, not the ongoing regulation of tanks. RCRA provides the general framework for hazardous waste management, of which the UST program is a specific subset. The LUST Trust Fund relates to funding cleanup after leaks, not the regulatory requirements themselves. In short, the UST program is the regulation that directly governs underground storage tanks.
