SACRAMENTO - The Air Resources Board is reminding truck and bus owners to check now to see if their vehicle fleets are among those that will have new rules to follow as of Jan. 1, 2013.

As the new year begins, heavy duty trucks and buses (more than 26,000 lbs. gross vehicle weight rating) with 2000 – 2004 model year engines will likely need diesel soot filters as required by the state’s Truck and Bus Regulation.  The rule is part of California’s Diesel Risk Reduction Plan, which includes a suite of regulations designed to reduce harmful diesel emissions from a wide variety of sources.  In 2011, similar requirements took effect for 1996 – 1999 model year engines.

There are exceptions (low-mileage or emergency vehicles, etc.), however, the majority of registered trucks and buses in this vehicle category will need to take steps to comply with the regulation.  

“Our efforts to reach out to the trucking industry have yielded positive results,” said ARB’s Enforcement Division Chief James Ryden.  “We have enforcement and compliance assistance teams all over the state who regularly inspect vehicles and educate owners, and recently, we’ve been pleased to note a compliance rate of more than 80 percent.”  Ryden specifically cited “Gear Up for Clean Truck Month” in August 2012, where teams of ARB and California Highway Patrol officers stepped up enforcement efforts and inspected more than 4,000 trucks at 40 different locations, including CHP weigh stations, random roadside areas, distribution centers, fleet facilities, truck stops and other sites where trucks and buses are present.

Business owners should note that non-compliant vehicles (including out-of-state vehicles) may not be legally operated in California.  Penalties start at a minimum of $1,000 per violation per month and will increase significantly over time.  In addition, non-compliance can result in a Department of Motor Vehicle registration block on your truck or bus, and/or having your vehicle impounded by CHP until it is in compliance.  For more information on possible penalties, see the “Enforcement” link at Truck Stop/Enforcement. 

Other new diesel-related rules besides the Truck and Bus Regulation will be enforced starting Jan. 1, 2013.  Vehicle owners may want to take note of this information in order to place equipment orders and prepare for compliance.  Deadlines coming up quickly for diesel vehicles include:

December 31, 2012:  

• Transport Refrigeration Units with 2005 model year engines must be replaced with Ultra-Low-Emission TRUs.

January 1, 2013:

• Under the Truck and Bus regulation, diesel truck and bus fleets must either install diesel soot filters (or upgrade equipment) on trucks with 2002 – 2004 model year engines or meet phase-in option requirements. 
• For vehicles covered under the Drayage Truck Regulation, 2005 – 2006 engine model year trucks greater than 33,000 lbs. gross vehicle weight rating must have diesel soot filters.
• Tractor-Trailer Greenhouse Gas regulation:
  • Owners of fleets with 20 or fewer affected trailers must register if they want to use a compliance option that will allow them up to four additional years to participate in the Small Fleet Compliance Plan.
  • Low-rolling resistance tires are required for 2010 model year and older tractors that pull 53 foot-long box-type trailers. 
  • SmartWay aerodynamic requirements must be met by all 53-foot or longer box-type trailers not using a phase-in option. 

To make sure you and your fleet are ready for 2013, call 1-866-6-DIESEL (1-866-634-3735), or visit ARB’s Truck Stop for more information.
