Underground Storage Tank (UST) Program

Office of Tank Tester Licensing Program

The SWRCB administers the Tank Tester Licensing Program to protect human health and the environment by establishing minimum qualifications for those who test underground storage tanks and associated piping. The SWRCB licenses and regulates tank testers under the provisions of Health and Safety Code, Chapter 6.7, Section 25284.4, and the California Code of Regulations, Title 23, Division 3, Chapter 17, Sections 2730 through 2802. In accordance with Chapter 16, Section 2637, a tank tester's license may also be used to conduct annual monitoring and secondary containment testing at operating UST facilities. Guidelines for using your tank tester license to conduct these types of tests can be found in Chapter 16, Section 2637 of the California Code of Regulations.
