By what date was under dispenser containment (UDC) required for all UST systems?

January 1, 2000
December 31, 2003
June 30, 2005
December 31, 2005

The correct answer is: December 31, 2003

Under dispenser containment (UDC) was required for all underground storage tank (UST) systems by December 31, 2003. The requirement for UDC is part of the regulations intended to prevent leaks and spills from fueling operations at the dispensers. Implementing UDC is a significant part of the overall strategy for enhancing the safety and environmental protection measures for UST systems. The timeline for these requirements was guided by legislative efforts to improve UST safety standards and ensure that adequate containment measures were in place to minimize environmental risks associated with fuel storage. By mandating UDC by this date, regulatory agencies aimed to reduce the likelihood of product release into the environment during fuel transfer operations, which is crucial for safeguarding soil and groundwater quality. Subsequent dates in the other options represent deadlines for other stages of UST regulatory compliance or requirements that either reinforced original mandates or introduced new measures, rather than being the initial implementation date for UDC. This timeline allows operators and facility owners to prepare and comply with essential safety standards, protecting both public health and the environment.
