Key Provisions of Regulation

The State Water Resources Control Board (State Water Board) has amended California Code of Regulations, title 23, division 3, chapter 16 (California Underground Storage Tank (UST) Regulations).  These amendments include both modifications to the local agency reporting requirements and modifications to the reporting requirements for UST owners and operators.  The effective date of these amendments is October 1, 2020.


The State Water Board has amended the requirements in California UST Regulations, section 2713 regarding the data that local agencies must provide semi-annually to the State Water Board.  The UST performance measures that the State Water Board reports to the United States Environmental Protection Agency (U.S. EPA) under the Federal Leaking Underground Storage Tank Trust Fund Corrective Action Cooperation Agreement for California and the State Water Board Cooperative Agreement Work Plan (federal UST performance measures) were amended and are known at the Technical Compliance Rate.  In addition to these federal UST performance measures, the State Water Board must report compliance inspection data to the U.S. EPA pursuant to the Federal Energy Policy Act of 2005.

Additionally, the State Water Board included to section 2713 requirements that local agencies provide annual compliance inspection data using the California Environmental Reporting System (CERS), the statewide web-based system used to collect and report hazardous material related data.  Finally, the State Water Board simplified the existing local agency reporting requirement regarding red tags.  These amendments to the local agency UST performance measures were necessary so that the State Water Board can provide complete and accurate reporting of all federal UST performance measures to the U.S. EPA.

The State Water Board also amended the requirements in California UST Regulations, section 2716 to clarify UST owners and operators designated UST operator visual inspection responsibilities.  This amendment requires the UST Owner or Operator to sign the designated operator visual inspection report within 72 hours of receipt, acknowledging the inspection results on the “Designated Underground Storage Tank Operator Visual Inspection Report.”

The State Water Board substantially modified several of the forms in regulation.  The communication testing requirement has been removed from the Monitoring System Certification Form and the Secondary Containment Testing Report Form.  Structural changes to the forms were added to simplify use by the UST owners, operators, and the local agencies and constructed to be accessible for all users.
