The California Air Resources Board (ARB) has released a revised draft of their proposed On-Road Diesel Regulations.  Their intention is to regulate large, heavy duty diesel trucks.  

The rule outlines a comprehensive program requiring two retrofits or replacements of all on-road diesel vehicles (over 14,000 gross vehicle weight rating) doing business in California to meet acute NOX (nitrogen oxide) and PM (particulate matter) standards and to help achieve greenhouse gas (GHG) goals by 2020.  

The October 2007 proposal calls for all diesel trucks to meet the 2007 model engine standards by 2014.  Engines made prior to 2007 would be banned in 2010 unless the ARB makes exceptions for expensive and complicated technology and if its available.  The second phase of the program would require 2010 engine standards by 2020.  In addition, ARB also intends to include in the regulations all vehicles used exclusively off-road, but built for on-road use, such as vehicles not already enrolled in the recently adopted off-road diesel vehicle registration.

ARB implemented a similar rule change in June for large off-road diesel vehicles although staff received expert testimony that compliance could amount to roughly $13 billion rather than the $3 billion estimated by staff.

The current incentive funding mechanisms authorized under California law are not sufficient to pay for the costs of compliance.  ARB expects the costs to be passed through to consumers in the form of higher prices for goods and services.  As we know, while this contention has some validity, it is far from reality.  The impact of these regulations on goods movement costs and manufacturing in this state could potentially be very, very significant.  We have heard estimates from trucking companies that these regulations could cause shipping rates to jump as high as 82%.  

The proposal is planned to go before the Board for approval next summer.

The process for adopting the new regulations is lengthy and this is just the start. CMTA has joined a coalition of agriculture, trucking and the business community leaders concerned with this proposed rule.
