As of what date must all pressurized products piping with secondary containment be equipped with an Automatic Line Leak Detection capable of detecting a 3 GPH release?

  1. January 1, 2000

  2. November 9, 2004

  3. July 1, 2005

  4. December 31, 2006

The correct answer is: November 9, 2004

The requirement for all pressurized product piping with secondary containment to be equipped with an Automatic Line Leak Detection (ALLD) system capable of detecting a 3 gallons per hour (GPH) release is rooted in environmental safety regulations aimed at preventing contamination from fuel leaks. The date, November 9, 2004, signifies a critical regulatory deadline established by the United States Environmental Protection Agency (EPA) and state regulations, which mandates that such leak detection systems must be in place to enhance monitoring and minimize risks associated with the storage and handling of hazardous materials. The focus on 3 GPH detection ensures that any significant leak can be identified swiftly, allowing for immediate remedial actions to be taken. Implementing these systems is a fundamental part of modern underground storage tank (UST) management practices, reflecting advancements in technology and the importance of preventing environmental contamination through effective monitoring solutions.
