Stations are usually given notice for some inspections but may be inspected without prior notice if a complaint or evidence of tampering exists.

Keep maintenance logs and meter calibration receipts for at least the period recommended by the sealer.
  • Documentation: operators should have test tags, calibration certificates, and service records available for inspectors.
