  3. Contents Introduction Smog Check Overview Inspection Procedures Smog Check Inspection Video

  4. Bureau of Automotive Repair The Bureau of Automotive Repair (BAR) is charged in law with implementation and oversight of the Smog Check Program. BAR licenses stations and inspectors who perform Smog Check Inspections and/or repairs BAR certifies inspection equipment, and oversees industry compliance with Smog Check Program laws and regulations BAR, with help from Air Resources Board (ARB), establishes emissions standards for vehicles BAR, with help from ARB, analyzes Smog Check Program compliance with state and federal performance requirements

  5. Why Smog Check? The Smog Check Program is a major component of the State of California’s ongoing efforts to reduce air pollution caused by emissions from cars and trucks. According to the California Air Resources Board (ARB), the Program is responsible for removing approximately 400 tons of smog-forming pollutants from California’s air every day.

  6. What is Smog? • The word smog is derived from two words: smoke and fog. Smog is produced by vehicular and industrial emissions • Photochemical Smog is the result of the chemical reaction of sunlight, Nitrogen Oxides (NOₓ) and Volatile Organic Compounds (VOCs) in the atmosphere • This chemical reaction results in poor air quality

  7. What is Ozone (O3) Ground Level Ozone (O3) is a by-product of the reaction between Hydrocarbons (HC), Nitrogen Oxides (NOₓ), and sunlight. Both HC and NOₓ are components of vehicle exhaust. Ozone can: Irritate the respiratory system Worsen the effects of asthma and bronchitis Reduce the body’s ability to fight off bacterial infections in the respiratory system Inflame and damage the lining of the lungs and reduce lung function Aggravate chronic lung diseases, such as emphysema

  8. Health Effects of Smog Despite significant success in improving air quality in California, air pollution continues to be a serious public health problem Health-based ambient air quality standards, which include standards for pollutants such as ozone and particulate matter, are set by the Air Resources Board Long-term exposure to these pollutants may lead to serious health effects, such as cancer, even when the exposure level is low Both air pollutants and toxic air contaminants are measured statewide to monitor the success of programs, such as the Smog Check Program, in improving air quality

  9. Sources of California Air Pollution • Data compiled from the most recent California Air Resources Board's Emissions Inventory report. • **Residential fuel combustion, farming operations, construction, road dust, wind-blown dust, fires, waste burning, utility equipment and other miscellaneous processes.

  10. Motor Vehicle Emissions Hydrocarbons (HC):HC emissions from a vehicle are unburned fuel. High levels of HC emissions may indicate incomplete fuel combustion. Low engine compression also can produce high HC tailpipe emissions. The Smog Check Program measures HC in parts per million (PPM). Carbon Monoxide (CO): CO is a colorless, odorless gas that can be fatal. CO emissions are often the by-product of an overly rich fuel mixture. The Smog Check Program measures CO as a percent (%) of vehicle exhaust volume.

  11. Motor VehicleEmissions Nitrogen Oxide (NOₓ) is an odorless gas that contributes to smog. Excessive combustion chamber temperatures are the primary cause of NOx, which could be caused by: Lean air/fuel mixture Advanced ignition timing Carbon buildup in the combustion chamber Malfunctioning Exhaust Gas Recirculation (EGR) Malfunctioning engine cooling system The Smog Check Program measures NOx in parts per million (PPM).

  12. Smog Check Overview This section discusses the requirements of the Smog Check Program, including requirements for testing, licensing and program areas. Vehicles Subject to Smog Check Program Smog Check Program Areas When is a Smog Check Required? Licensed Inspector Requirements Licensed Station Requirements Smog Check Station Types Inspection Requirements by Program Area

  13. Vehicles Subject to the Smog Check Program Gasoline powered vehicles: • 1976 and newer model years • No GVWR limit Alternative fuel vehicles (Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG) and Flex Fuel powered vehicles): • Over 14,000 GVWR Diesel powered vehicles: • 1998 and newer model years • 14,000 GVWR and less

  14. This section covers the three geographic areas of the Smog Check Program: Enhanced Basic Change of Ownership Smog Check Program Areas These areas determine when a Smog Check is required and the type of inspection required.

  15. When is a Smog Check Required? Enhanced and Basic Areas • Biennially (every other year) as part of registration renewal for vehicles that are more than six model-years old • Upon change of ownership of vehicles that are more than four model-years old Exemption does not apply to diesel powered vehicles • Upon initial registration of a vehicle in California Change of Ownership Areas • Upon change of ownership of vehicles that are more than four model-years old Exemption does not apply to diesel powered vehicles • Upon initial registration of a vehicle in California

  16. Licensed Inspector Requirements To become a licensed Smog Check Inspector, the candidate must: • Meet minimum experience requirements • Meet minimum training requirements • Pass a BAR licensing examination

  17. Licensed Station Requirements To become a licensed Smog Check Station, the facility must: • Be registered with BAR as an Automotive Repair Dealer (ARD) • Meet minimum equipment and facility requirements • Employ licensed inspectors • Retain service and repair records for three years

  18. Smog Check Station Types • Test-Only:These licensed stations can only test and certify vehicles; they are prohibited by law from performing any diagnostics or repairs • Test-and-Repair:These licensed stations can perform both inspections and repairs on most vehicles Some licensed test and repair stations (STAR) have met certain performance standards to be eligible to test and certify all vehicles. They also perform repair assistance services under BAR’s Consumer Assistance Program (CAP) • Repair-Only: These licensed stations can only perform diagnosis and repairs on most vehicles; they are prohibited by law from performing any Smog Check tests

  19. Enhanced Areas 1976 and newer model-year vehicles require a Smog Check inspection every two years at the time of their DMV registration renewal 1976 and newer model-year vehicles require a Smog Check Inspection upon change of ownership All vehicles subject to the Smog Check Program require inspection upon initial registration in California Some vehicles are required to obtain a Smog Check certificate from a STAR Test and Repair or STAR Test-Only Most vehicles require an Acceleration Simulation Mode (ASM) emissions test using a dynamometer • Inspection Requirements by Program Area

  20. Inspection Requirements by Program Area • Basic Areas • Most vehicles require a Smog Check Inspection every two years at the time of their DMV registration renewal • Most vehicles require a Smog Check Inspection upon change of ownership • All vehicles require a Smog Check Inspection upon initial registration in California • Vehicles only require a Two-Speed Idle (TSI) emissions test

  21. Change of Ownership Areas 1976 and newer model-year vehicles require a Smog Check Inspection upon change of ownership All vehicles subject to the Smog Check Program require inspection upon initial registration in California Vehicles only require a Two-Speed Idle (TSI) emissions test Inspection Requirements by Program Area

  22. This section provides a quick overview of the Smog Check Inspection, including how the results are reported. Vehicle Verification Smog Check Inspection Elements Overview of Smog Check Procedures Reporting Smog Check Results Inspection Procedures

  23. The Licensed Smog Check Inspector: Verifies that the vehicle matches the DMV renewal form Enters a confidential access code into the Emissions Inspection System (EIS) Scans the DMV renewal form into the EIS Manual entry is allowed if the DMV renewal form is not available Enters vehicle information as required following EIS prompts Vehicle Verification

  24. Visual Inspection Licensed inspector carefully examines the vehicle’s emissions control systems to ensure they are connected and have not been tampered Emissions Test Licensed inspector uses the EIS to measure a sample of the exhaust emissions produced by the vehicle Functional Test Licensed inspector tests the operation of certain emissions control systems to ensure they are working properly • Smog Check Inspection Elements

  25. Overview of Smog Check Procedures

  26. EIS determines if the vehicle passes or fails the overall inspection EIS transmits test results to BAR’s central database EIS prints out test results on a Vehicle Inspection Report (VIR) Licensed inspector signs and dates the VIR under penalty of perjury and provides a copy to the consumer Passing test results are transmitted to DMV for vehicle registration Reporting Smog Check Results
