As of December 31, 2003, all USTs must be retrofitted with what?

  1. Electronic leak detectors

  2. Under Dispenser Containment

  3. Overfill protection systems

  4. Double-walled tanks

The correct answer is: Under Dispenser Containment

The requirement for all Underground Storage Tanks (USTs) to be retrofitted with Under Dispenser Containment (UDC) systems by December 31, 2003, is grounded in the need to enhance environmental protection and safety at fueling sites. UDC systems are designed to collect any leaks or spills that may occur during the dispensing of fuel, thereby preventing them from contaminating the surrounding soil and groundwater. This regulatory update was part of a broader effort to improve the integrity of UST systems and minimize the risks associated with hazardous materials. Utilizing UDC helps ensure that minor leaks are detected early, allowing for prompt action to be taken before they escalate into more significant environmental issues. Retrofits with UDC therefore play a critical role in the overall management and safety of UST operations, meeting compliance requirements while safeguarding public health and the environment. This reflects a commitment toward better practices in the management of underground storage systems and is a key aspect of regulatory compliance for facilities that store regulated substances.
