Smog Check Station Audits and InspectionsBAR routinely conducts audits and inspections of stations across the State to verify the proper functionality and accuracy of emissions testing equipment used in the Smog Check Program. When defective or improperly functioning emissions analyzer equipment is identified, BAR staff work with the station to ensure necessary corrections are made.
A Smog Check station audit and inspection includes the following:
- Visual Inspection - examination of all peripheral hardware attached to the emissions analyzer, including inspection of calibration gases and zero air
- Functional Inspection - examination of the functionality of the emissions analyzer, including calibration and leak checks as necessary
- Gas Audit - introduction of certified gas values into the emissions analyzer sample system to ensure equipment is operating within acceptable tolerances
- Inspection Report - documentation provided to stations at the conclusion of the audit and inspection that identifies any problems that require correction
