How often must containment sump testing be conducted for sumps used for piping interstitial monitoring?

Every year
Every 3 years
Every 5 years
Only when repairs are made

The correct answer is: Every 3 years

Containment sump testing for sumps used for piping interstitial monitoring is required to be conducted every 3 years. This frequency is established to ensure that the sumps remain effective in preventing leaks and contain any potential releases of hazardous substances. The testing verifies that the integrity of the containment system is maintained and that it functions as intended to protect the environment and public health. Regular testing is essential as it helps identify any potential vulnerabilities or failures in the system that could lead to leaks. By adhering to the three-year testing schedule, operators can ensure that their containment sumps are adequately monitored and maintained, which is crucial for the compliance with environmental regulations and standards.
