arbcombo -- Compliance When PM Filters are Required to be Removed or Sales/Installations are Suspended Posted: 30 Sep 2011 14:21:42
The California Air Resources Board (ARB or Board) staff has issued a Mail-Out to address compliance with existing in-use regulations, including early action credit eligibility, when a manufacturer of a verified diesel PM filter suspends sales and installations of a PM filter, or requires its removal for a particular engine family. This advisory only applies to vehicles subject to the following regulations: • Truck and Bus Regulation • Transit Fleet Vehicle Regulation • Urban Bus Regulation • Public Agency and Utility Fleet Regulation • Solid Waste Collection Vehicle Regulation • In-Use Off-Road Vehicle Regulation ARB is providing time for fleets affected by this to purchase and install other verified PM filters, or to allow for completion of approved modifications for PM filters that are removed by the manufacturer, without affecting fleet compliance or the ability of fleets to earn or retain early compliance credits. Under this advisory, if a PM filter manufacturer requires a verified PM filter to be removed from a particular engine family, the fleet owner will have 90 days or until January 31, 2012, whichever is longer, to take appropriate action. During this period, the fleet owner will be permitted to operate any affected vehicles in their original equipment manufacturer configuration without a PM filter. The fleet owner must keep records of the change as specified in the applicable regulation. The Mail-Out #11-29 is available at: http://www.arb.ca.gov/msprog/mailouts/mouts_11.htm For other information about diesel vehicle in-use regulations, please visit Truck Stop: http://www.arb.ca.gov/truckstop . If you have any additional questions, please call 866-6DIESEL (866-634-3735) or email at: firstname.lastname@example.org Background The Air Resources Board has adopted a number of regulations that require diesel engine owners to take steps to reduce their engine emissions. 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 to reduce exhaust emissions between now and 2023. Similar requirements will also become effective in the next several years effecting owners and operators of certain off-road equipment (including equipment used in construction, industrial, and airport operations). To comply with these requirements, fleet owners can upgrade exiting engines by installing PM filter retrofits or other Verified Diesel Emission Control Strategies (VDECS), or by upgrading to cleaner engines. These regulations are part of the State’s plan to meet federal ambient air quality standards and to protect public health.
