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.

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.
