California ICC UST Inspector Practice Exam

When was under-dispenser containment required for all UST systems?

1. December 31, 2003

2. July 1, 1987

3. January 1, 1984

4. January 1, 2000

The correct answer is: December 31, 2003

Under-dispenser containment became a requirement for all Underground Storage Tank (UST) systems on December 31, 2003, as part of the regulatory efforts aimed at reducing the risk of leaks and spills from fuel dispensers. This regulation was established due to growing concerns about environmental contamination and the need for improved safety measures in the storage and dispensing of petroleum products. The implementation of under-dispenser containment systems helps capture any leaks that may occur from the hoses or dispensers, thereby preventing fuel from escaping into the environment. This requirement underscores the evolving regulations aimed at enhancing environmental protections and safety. While several other dates listed correspond to prior regulations and requirements regarding UST systems, they do not pertain specifically to the mandate for under-dispenser containment, which was a significant step introduced in the early 2000s to strengthen UST management and ensure better containment practices.
