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.
