ARB adopts changes to California’s Truck and Bus Regulation


Provides limited additional time for small fleets while still protecting air quality


SACRAMENTO - The California Air Resources Board today adopted amendments to its Truck and Bus Regulation that will provide new flexible compliance options to owners of aging diesel fleets and recognize fleet owners that have made investments to comply, while also protecting air quality.
 
The changes approved at today’s Board hearing provide additional regulatory flexibility to small fleets, lower use vehicles, and fleets in rural areas that have made substantial progress towards cleaner air.  Fleets that have invested in cleaner, compliant equipment and trucks will be able to use credits longer and any vehicles retrofit by 2014 do not have to be replaced until 2023. 

“We recognize the enormous investments that many businesses have already made to clean up their equipment and abide by the terms of the regulation,” said ARB Chairman Mary D. Nichols, “but we are also aware that, particularly for many rural areas of the state, economic recovery has been painfully slow and funding for improvements scarce.
 
“By providing limited additional time for certain fleets to comply, we believe that we’ll have higher compliance rates overall.  It’s a difficult balance but we believe that this is a fair approach that offers flexibility to those who need it, while also rewarding those business owners who have already upgraded their vehicles to meet the requirements of the regulation.”

Nichols also said that the amendments, while potentially delaying compliance for some, will still protect air quality, preserving 93% of the NOx (oxides of nitrogen) and diesel particulate matter (PM) benefits of the original regulation. 

The amendments include:
The amendments will still ensure that, by 2020, nearly every truck in California will have a PM filter, consistent with the goals of the Diesel Risk Reduction Plan.

Diesel exhaust contains a variety of harmful gases and more than 40 other known cancer-causing compounds. In 1998, California identified diesel particulate matter as a toxic air contaminant based on its potential to cause cancer, premature death and other health problems.

ARB's mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The ARB oversees all air pollution control efforts in California to attain and maintain health based air quality standards.
