Fleet Calculator (1/26/2012):  The Fleet Calculator is an Excel spreadsheet to assist fleet owners in evaluating various compliance strategies to comply with the Truck and Bus Rule. It 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 has been updated to reflect the amendments adopted by the Board in December 2010.
