Tank Tester's License Requirements

New License

License Renewal

  • The Office of Tank Tester Licensing will send a renewal notice to licensees at least 90 days before their licenses expire. Additional notices may be given, however, even if licensees do not receive notification, they are obligated to renew their licenses if they plan to continue testing underground storage tanks in California. A Renewal Application and fee of $600 must be sent 30 days before the license expires. No examination is required to renew a license.


  • An expired license may be re-instated by filing a Re-instatement Application and submitting the re-instatement fee of $200 plus the renewal fee of $600.
