onrdiesel -- Regulatory Advisory on Compliance Extension for Manufacturer Delayss Posted: 09 Jul 2013 16:11:04
The Air Resources Board (ARB) has posted a regulatory advisory to clarify requirements of the extension for manufacturer delays in the Truck and Bus regulation (regulation). The manufacturer delay extension specified in section 2025(p)(8) of the regulation excuses the owner from immediate compliance with applicable particulate matter (PM) filter requirements if the PM filter, engine, or vehicle originally equipped with a PM filter was purchased at least 4 months prior to the compliance deadline and has not been received due to a manufacturer delay. This advisory clarifies the length of the temporary extension and how compliance is determined. For more information, please see the advisory at: http://www.arb.ca.gov/msprog/onrdiesel/regulation.htm Background ARB 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. 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.
