Fleet Calculator (7/30/2014):  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 if qualified.  This tool has been updated to reflect most of the amendments adopted by the Board in April 2014.  Provisions for heavy crane, small fleet, PM filter unavailability, 25% compliance limits, and economic hardship were not programmed into this version but will be included in the next update.  School bus requirements will not be in the calculator and should be calculated separately.
