According to regulations, what must individuals performing secondary containment testing possess?

Individuals performing secondary containment testing are required to have an appropriate contractor license or tank tester license because these credentials ensure that they have the necessary skills and knowledge to conduct the testing according to regulatory standards. This requirement reflects the importance of safety and compliance in the management of underground storage tanks, as improper testing can lead to environmental hazards or regulatory violations.

A contractor license or tank tester license implies a level of professionalism and training associated with the specific practices needed to accurately assess the integrity of containment systems. Without such qualifications, there is a significant risk of substandard work that could endanger public health and the environment.

While other certifications, such as environmental certification, training certificates in tank operations, or safety compliance certificates, are valuable in ensuring the overall competence and safety of individuals working with underground storage tanks, they are not strictly mandated for performing secondary containment testing as specified by the regulations.
