The California Air Resources Board (ARB or Board) staff has posted the fleet calculator to assist fleet owners in evaluating various compliance strategies to comply with the Truck and Bus Rule.

The compliance tool is an Excel spreadsheet that allows the user to input the engine model year, and emission control technology assumptions to determine what compliance options may be available to comply with the regulation for each calendar year.

Fleets can view automated compliance strategies for meeting the compliance schedule based on engine model year or can evaluate more flexible compliance strategies including the phase-in option, compliance credits, and special provisions. The tool is consistent with amendments considered by the Board in December 2010 and is available at: www.arb.ca.gov

For factsheets, training dates, and other information about the regulation please visit at: www.arb.ca.gov/dieseltruck. If you have any questions, please call 866-6DIESEL (866-634-3735)
