On-Road Heavy-Duty Diesel Vehicles
(In-Use) Regulation

The California Environmental Protection Agency is requiring that all owners of diesel trucks, buses, trailers and transport refrigeration units, or “reefers,” that operate in California,  take steps to reduce air pollution. Reducing emissions from existing equipment is necessary to meet federally imposed clean air standards and to reduce the adverse health effects from pollution. Funding opportunities may also be available to lower emissions earlier than required.

Diesel trucks and buses with a GVWR more than 14,000 lbs. that are owned by private or federal government fleets must reduce exhaust emissions by meeting particulate matter (PM) filter requirements and upgrading to 2010 model year (MY) or newer engines. In addition, any person residing in California who sells an affected vehicle must provide a disclosure notice about the regulation to the buyer.

HEAVIER VEHICLES with a GVWR more than 26,000 lbs. need engine upgrades as shown in the table.  No reporting is required if using the heavier vehicle schedule.

Schedule for Heavier Trucks and Buses
Engine Year PM Filter* 2010 MY Engine
Pre – 1994 Not Required January 1, 2015
1994 – 1995 Not Required January 1, 2016
1996 – 1999 January 1, 2012 January 1, 2020
2000 – 2004 January 1, 2013 January 1, 2021
2005 or newer January 1, 2014 January 1, 2022
2007 – 2009 Already Equipped January 1, 2023

* 50% PM reduction can be used if 85% reduction is not available.

 

LIGHTER VEHICLES with a GVWR 26,000 lbs. or less need to be upgraded to 2010 model year engines or to newer models as shown in the table. No retrofit PM filters or reporting is required if using the lighter vehicle schedule.

Schedule for Lighter Trucks and Buses
Engine Year 2010 MY Engine
Pre – 1994 January 1, 2015
1994 – 1995 January 1, 2016
1996 – 1999 January 1, 2020
2000 – 2004 January 1, 2021
2005 or newer January 1, 2022
2007 – 2009 January 1, 2023

ALL VEHICLES can be kept longer with early PM retrofit filters, and trucks operated in less polluted counties in California do not need to be upgraded to have 2010 model year engines if equipped with PM filters. Small fleets (1-3 trucks with a GVWR more than 14,000 lbs.) must report to delay compliance until January 1, 2014. Fleet owners must report to take advantage of these and other provisions.
