More Stringent Engine Requirements Take Effect In California

Trucks traveling in California face more stringent engine emissions requirements in 2014. Some limited exemptions are available but otherwise the following requirements are in effect.

Owner-operators with trucks having 1996-2006 engines are subject to new requirements which mandate retrofitting with CARB-approved diesel particulate filters (DPFs) or replacement with trucks having 2007 or newer engines.

Fleets with three or fewer trucks need to have at least one truck equipped with a DPF and register any unfiltered trucks with the California Air Resources Board (CARB).

Fleets with more than three trucks need to have trucks with 1996-2006 engines retrofitted with DPFs or replaced with trucks having 2007 or newer engines, unless they previously registered to phase-in compliance.
Drayage trucks operating in and out of the state's ports or rail yards need to have 2007 or newer engines.

Transport refrigeration units (TRUs) with 2006 engines need to have these engines or units replaced with newer models or retrofitted with DPFs.
CARB will be conducting compliance training webinars on Jan. 15, 27 and 29 in addition to in-person training at various locations throughout California.
