The California Air Resources Board (ARB) provides in a recent Regulatory Advisory the steps it is taking to assist vehicle owners with the transition to the upcoming January 1, 2014, particulate matter (PM) filter compliance deadline under the Truck and Bus Regulation.

Key dates from the background section of the ARB Regulatory Advisory are highlighted below including steps ARB requires to satisfy 'Good Faith Efforts'.

Here is the link to the ARB Truck and Bus Regulation On-Road Heavy-Duty Diesel Vehicles (In-Use) Regulation website with information about the regulation, questions and answers, compliance tools, reporting and exhaust retrofits and other background and resources.

From the ARB Regulatory Advisory:


The regulation requires diesel truck and bus owners to take steps to reduce their engine emissions. The regulation is a part of the State's plan to meet federal ambient air quality standards and to protect public health, particularly near roadways and distribution centers where exposures frequently reach unhealthy levels. Nearly all trucks and buses with a manufacturer's gross vehicle weight rating greater than 14,000 pounds that operate in California are required to be upgraded between 2012 and 2023 to reduce exhaust emissions.

Most heavier trucks and buses (with a gross vehicle weight rating greater than 26,000 pounds) are required to have a PM filter by January 1, 2014. There are certain exceptions to these requirements for truck owners that have reported to use flexibility options allowed under the regulation. These include, but are not limited to, certain agricultural and limited-use construction trucks, low-use vehicles, and vehicles that operate in certain areas of the State. Additional information about the regulation is at:

To comply with the PM filter requirements, owners can upgrade existing engines by installing PM filters that are Verified Diesel Emission Control Strategies approved by ARB, or by upgrading to cleaner engines or vehicles. A list of Verified Diesel Emission Control Strategies that have been approved by ARB can be found at:

Recognizing Good Faith Efforts to Comply

While the January 1, 2014, compliance date remains unchanged for most fleets, ARB will recognize good faith efforts of vehicle owners to comply with the deadline. Specifically, fleets of any size that demonstrate they took one of the following actions prior to January 1, 2014, and report into TRUCRS, will not be subject to enforcement action during the period through July 1, 2014, on any truck for which they:

  • Entered into an agreement with an authorized retrofit installer for a PM filter retrofit
  • Signed a purchase contract and ordered a replacement truck that is equipped with a PM filter (2007 model year engine or newer)
  • Were approved or denied a loan or other financing for a retrofit PM filter or for a replacement truck that is equipped with a PM filter
