Truck Maintenance & Emission Compliance with Confidence ™

PSIP Opacity

Are you in compliance with the California’s Periodic Smoke Inspection Program (PSIP)?

As of July 1, 2019, California Air Resources Board (CARB) reduced the opacity standards for all Heavy duty vehicles operating within the State of California. Vehicles greater than 6,000 GVWR must be tested annually. Opacity standards with a PM filter is 5%. Vehicles without a PM filter depend on year of engine and range from 20%-40%.

FleetCrew offer PSIP opacity testing to fleets in both a convenient mobile and fixed service capacity:

In response to public concerns about the public health impacts of heavy-duty vehicle smoke emissions, California law requires the owner’s trucks and bus fleets to perform annual inspections of their vehicles. Fleet owners are required to maintain inspection and repair/retest records for each vehicle. Fleet owners are not required to inspect vehicles that are powered by diesel engines until after the 4th model year of the engine. To ensure compliance, the Air Resources Board will randomly audit fleets maintenance and inspection records and test a representative sample of vehicles.

All testing must conform to the Society of Automotive Engineers’ (SAE) J1667 snap-acceleration test procedure. All vehicles that do not pass the test must be repaired and retested. All testing must be performed using an SAE J1667 smoke meter. All testing records must be maintained for a period of two years.
