  • Is there a designated station manager with current license on file responsible for program compliance?

Test Data Integrity & Electronic Reporting

Audit the accuracy, completeness, and timeliness of vehicle test data submission to state I/M program databases.

  • Is the station's data link to the state I/M central database operational and transmitting test records in real time or within required intervals?
  • Are test record rejection rates from the state database below the program threshold (typically <2% of submitted records)?
  • Are all voided or aborted test records documented with valid reason codes per state I/M program requirements?
  • Does a review of a sample of 10 recent test records confirm VIN, license plate, and odometer data match vehicle documentation?
  • Are backup procedures in place for data storage and recovery in the event of a system outage?

Vehicle Test Procedure Compliance

Verify that testing procedures are consistently followed for all vehicle types in compliance with program protocols.

  • Are inspectors consistently following the state-approved pre-test visual inspection checklist before each tailpipe test?
  • Are idle and/or 2500 RPM test procedures being conducted for the correct duration per state I/M program protocol?
  • Are OBD II readiness monitors being checked and documented for all applicable model year vehicles?
  • Are vehicle exemptions (e.g., model year, vehicle type) being correctly applied per current state I/M program rules?
  • Are inspectors issuing waiver documentation to vehicles that fail testing and meet repair cost waiver thresholds?

Fee Schedule, Consumer Transparency & Anti-Fraud Controls

Audit compliance with approved fee schedules, consumer disclosure requirements, and anti-fraud program controls.

  • Are the station's current test fees within the maximum fee limits approved by the state I/M program?
  • Are approved test fee schedules publicly posted in the customer waiting area per state program requirements?
  • Has the station had zero substantiated consumer fraud complaints filed with the state I/M program in the past 12 months?
  • Are station employees prohibited from performing repairs on vehicles they have just tested for emissions (conflict of interest)?
  • Are inspection certificates (stickers, electronic records) stored securely and accounted for with no unexplained discrepancies in inventory?

Occupational Safety & Emergency Preparedness

Confirm that occupational safety programs, emergency procedures, and PPE requirements are fully implemented.

  • Is a current written Hazard Communication (HazCom) program available and do SDSs exist for all hazardous chemicals on-site?
  • Are emergency evacuation procedures posted and have all station employees participated in an evacuation drill within the past 12 months?
  • Is a fully stocked first aid kit available and accessible in the testing area, with contents inspected within the last 6 months?
  • Are required personal protective equipment items (gloves, safety glasses) available and used by inspectors during testing?
  • Are all identified safety deficiencies from the prior year's audit documented as resolved with supporting corrective action records?
  • Has a photo record of the facility's current condition been captured to document this audit?

Corrective Action Plan & Certification Readiness Summary

Summarize audit findings, document corrective actions required, and assess overall station readiness for state certification renewal.

  • Has the total number of non-conformance findings been recorded and categorized by severity (critical, major, minor)?
  • Have corrective action deadlines been assigned for each non-conformance finding identified in this audit?
  • What is the total number of non-conformance findings identified in this audit?
  • Based on this audit, does the station meet overall requirements for annual certification renewal without conditional restrictions?
  • Please provide any additional audit observations, findings, or recommendations not captured in prior sections.
