As of December 31, 2003, what must all underground storage tanks (USTs) be retrofitted with?

Overfill protection
Under Dispenser Containment
Leak detection equipment
Emergency shutdown systems

The correct answer is: Under Dispenser Containment

The requirement for underground storage tanks (USTs) to be retrofitted with under dispenser containment reflects a significant aspect of safety and environmental protection. Under dispenser containment systems are designed to capture leaks that may occur from dispensers, which are critical points for fuel transfer. This measure is essential to prevent petroleum products from spilling onto the ground, thereby reducing the risk of contamination of soil and groundwater. The regulation mandates that UST systems incorporate features that prevent leaks and promote safety in the operation of fuel dispensing systems. This not only helps in complying with environmental regulations but also enhances operational safety by addressing potential risks at the dispenser level. In the context of this question, the choice of under dispenser containment directly aligns with regulatory efforts to improve the integrity of UST systems and minimize environmental hazards associated with the release of hazardous substances from these tanks.
