onrdiesel -- Truck and Bus Fleet Calculator Update Posted: 31 Jan 2012 11:04:25
The California Air Resources Board (ARB or Board) staff has posted an updated version of the Fleet Calculator. The Fleet Calculator is an Excel spreadsheet to assist fleet owners in evaluating various compliance strategies to comply with the Truck and Bus regulation. This update (version C) now includes a compliance option for log trucks, and corrects the alternative fueled vehicle credit calculation. No other significant changes were made. The new version is available at: http://www.arb.ca.gov/msprog/onrdiesel/compliancetool.htm The Fleet Calculator is an Excel spreadsheet to assist fleet owners in evaluating various compliance strategies to comply with the Truck and Bus regulation. The calculator allows the fleet owners to input the engine model year, and emission control technology assumptions to determine what compliance options may be best for the fleet each calendar year. Fleet owners can view automated compliance strategies for meeting the compliance schedule based on engine model year or can evaluate more flexible compliance strategies including the PM filter phase-in option, compliance credits, and special provisions. For other information about the regulation, please visit http://www.arb.ca.gov/dieseltruck. If you have any questions, please call 866-6DIESEL (866-634-3735) or email at: firstname.lastname@example.org Background On December 11, 2008, the Board approved for adoption the Truck and Bus regulation to control emissions from nearly all existing diesel powered heavy-duty trucks and buses operating in California. The regulation became effective under California law on January 8, 2010. On December 17, 2010, the staff recommended amendments to the regulation that were subsequently adopted by the Board on September 19, 2011. The Office of Administrative Law approved the amendments on December 14, 2011 and the regulation became effective on the same day. The amended Truck and Bus Regulation delays the initial requirement to phase-in installation of PM filters by one year to January 1, 2012 and extends the time before a vehicle equipped with a PM filter would have to have an engine that meets 2010 model year emission standards. The amendments also defer initial engine replacements for older vehicles without PM filters for two years until January 1, 2015 at the earliest. Prior to 2020, replacements are limited only to 20 year old or older trucks that are not equipped with PM filters. By January 1, 2023, most vehicles will need to be equipped with an engine meeting 2010 model year emission standards.
