At the end of 1999, the EPA adopted the Compliance Assurance Program (CAP2000). This introduced the In-Use Verification Program (IUVP) as a requirement for all manufacturers.

The IUVP is a vehicle testing program to monitor emissions and fuel economy for low and high mileage owner vehicles. It allows government agencies and industry to identify potential concerns that may require additional investigation.

Your car has a specific engine/evaporative system that is required to be monitored under EPA's Compliance Assurance Program (CAP2000). Depending on the car, we will perform a set of emissions tests, which measure evaporative emissions and tailpipe exhaust emissions.

The letter sent to you will include all of the available incentives for participating in this program. This will include the incentive check ($$$) and loan vehicle instructions.

In addition, you will also be helping automotive manfacturers and the EPA improve air quality by monitoring emissions.

Your car will undergo a set of emissions tests, depending on what is required by EPA at the time. This may include the following:

Tailpipe Emissions Testing
• Cars may perform tailpipe emissions tests, which consists of securing the car on a dynamometer and connecting an exhaust gas analyzer to the tailpipe
• The car's tires rotate on the dynamometer rollers as the vehicle is "driven" to simulate both city and highway driving
• Testing accumulates approximately 100 miles on the vehicle, in addition to the miles accumulated from transporting the vehicle to and from the testing facility. No additional mileage will be incurred besides emissions testing and transporation between pick-up and drop-off.

Evaporative Emissions Testing
• Some cars are selected for passive evaporative emissions testing (ex. tires and certain plastics emit small amounts of various gases). This passive testing also also checks for any fuel vapor leakage).
• Selected cars are put in a sealed room (SHED) for two days, while the air quality is continually monitored.
• Selected cars are also tested for On-board Refueling Vapor Recovery (ORVR), where the air quality is continuously monitored as the fuel tank is being filled.

The physical condition of your car will also be documented upon laboratory check-in and check-out to ensure that your car will arrive and depart in the same physical condition.

All IUVP tests will take place at our Ontario, California laboratory. The address is:

Automotive Testing and Development Services, Inc.
400 S Etiwanda
Ontario, California 91761

We are a third-party, independent laboratory that is not associated with any automotive company. We have contracts with certain automotive manufacturers that request us to perform some of the IUVP testing on their behalf.

Part of the contract requires that we procure the selected cars, perform the emissions testing, and return the car in the same condition as we receive it.

If you have additional questions regarding IUVP testing, please contact us directly or contact your manufacturer to verify details.
