Just received this information from CARB:
Be aware that some companies are advertising and attempting to sell devices that cannot be used to comply with Air Resources Board (ARB) diesel engine regulations. Only diesel particulate matter (PM) filters or other devices that have been verified by the ARB to meet rigorous emission reduction and durability demonstration requirements can be used to comply. Diesel PM filters that have been verified by the ARB are listed at http://www.arb.ca.gov/diesel/verdev/vt/cvt.htm. Be sure to check that any device you are considering is on this list. You may also choose to contact an authorized installer to learn more about verified PM filter retrofit options at http://www.arb.ca.gov/msprog/decsinstall/decsinstall.htm.
In addition, diesel engines that operate on biodiesel or have been modified to operate in combination with diesel fuel and alternative fuels must still meet the same emission reduction requirements as other diesel engines and are not exempt from the regulations.
For additional information about in-use diesel engine requirements, please visit the Truck Stop at: http://www.arb.ca.gov/truckstop, call 866-6DIESEL (866-634-3735) or email us at: [email protected]
Background:
The Air Resources Board has adopted a number of regulations that require diesel engine owners to reduce toxic air pollution emissions. These regulations are part of the State’s plan to meet federal ambient air quality standards and to protect public health. Between 2012 and 2023, nearly all trucks and buses that operate in California with a manufacturer’s gross vehicle weight rating greater than 14,000 pounds will need to upgrade to reduce exhaust emissions. Similar clean-up requirements are already in effect for operators of vehicles in drayage operations (ports and rail) and transport refrigeration units (reefers), Additionally, comparable requirements for owners of certain off-road equipment, including equipment used in construction, industrial, and airport operations, will take effect soon. To comply with these requirements, fleet owners may retrofit existing engines by installing ARB verified diesel PM filters or by upgrading to newer cleaner engines.
