UST Reporting Regulation Update – Jan 2021

January 1, 2021

As of October 1, 2020, revised forms for testing and inspections are required for Underground Storage Tanks (USTs). The new forms can be found on the SWRCB website and must be used in lieu of the forms released in October 2018.  The revised forms are for monitoring system certifications, secondary containment testing, spill containment testing, overfill prevention equipment, Designated Operator (DO) identification, and DO visual inspections.

In addition to revising the forms, 23 CCR Section 2713 was also amended to add a reporting requirement for Certified Unified Program Agencies (CUPAs) to report facilities where a compliance inspection has not been performed over that pervious calendar year. In addition, the UST owner or operator is now required to sign DO visual inspection reports within 72 hours of receipt, acknowledging the inspection results.

Owner Statement of Designated UST Operator Compliance

There has been some confusion regarding what forms need to be submitted in the UST section of the California Environmental Reporting System (CERS) and when they need to be updated. The regulation requires the Designated Underground Storage Tank Operator Identification Form (DO Form) to be resubmitted whenever the DO information changes, as well as the Statement of Understanding and Compliance Form (SOUAC Form) if a change in facility owner/operator occurs. However, it is always useful to check with your local CUPA inspector since local CUPAs vary in how they implement regulations.

Overfill Prevention Equipment Inspection

The initial Overfill Prevention Equipment Inspection was required by October 13, 2018. Some facilities completed their initial inspection after this date. This inspection is due every 36 months, however, regardless of when the initial inspection was completed. This means the second 3-year inspection must be completed by October 31, 2021, and every 36 months thereafter, irrespective of whether the initial inspection was completed on time.
