California Designated Operator Practice Exam

What is the testing frequency requirement for new secondary containment systems?

1. Once a year after installation

2. Immediately upon installation and every 36 months thereafter

3. Every 5 years after installation

4. Six months after installation and every 36 months thereafter

The correct answer is: Six months after installation and every 36 months thereafter

The testing frequency requirement for new secondary containment systems is designed to ensure that these systems remain effective in preventing leaks and spills that could harm the environment. The correct answer specifies that testing should occur six months after the initial installation, followed by subsequent testing every 36 months. This timeline reflects the need for diligent oversight on newly installed systems to catch any potential issues early on and to verify that the containment remains functional over time. By implementing an initial test within six months, operators can identify and address any immediate problems that may arise after installation, ensuring the integrity of the containment system. The requirement for ongoing testing every three years thereafter reinforces the importance of maintaining the system's effectiveness, allowing for regular assessments and maintenance to be performed. The other choices either suggest a less frequent testing schedule or do not provide an immediate post-installation test, potentially allowing undetected issues to develop. Therefore, the outlined testing frequency ensures a proactive approach to environmental safeguarding through timely and consistent evaluation of secondary containment systems.
