Oversight Inspection

State Water Board Evaluation staff will reach out to the CUPA to schedule the oversight inspection. During the inspection, the evaluation staff ensures that the inspector conducts a thorough inspection, and that any non-compliance is observed and documented in the inspection report.

Note: Evaluation staff will prioritize single-walled UST inspections during the evaluation.

Pre-inspection preparation:

  • Review the facility files to identify previous violations and enforcement actions
  • Review CERS to ensure all required documents are uploaded and current
  • Review CERS to verify the accuracy of information on the Tank Information/Monitoring Plan

Note: Evaluation staff may request testing documents/files before the oversight inspection, in addition to the information reviewed on CERS.

During the inspection, evaluation staff verify that the inspector reviews the following items:

  • Confirm that the service technician’s certifications and licenses are current
  • Confirm the UST construction and monitoring are consistent with CERS UST Tank Information/Monitoring Plan
  • Confirm the UST construction is consistent with HSC Chapter 6.7 and CCR Chapter 16
  • Review the in-tank set up and alarm history

  • Verify that the leak detection equipment is positioned to detect leaks at the earliest opportunity
  • Line leak detectors are tested to detect a 3.0 gph leak, and testing equipment is calibrated
  • Ensure that a tag/sticker is affixed to monitoring equipment that has been certified, repaired, or replaced
  • Ensure spill containers are tested for functionality
  • Confirm that overfill prevention equipment is installed and inspected/tested every 36 months
  • Ensure that secondary containment is free of water for USTs installed after July 1, 2003
