Fleet Average Calculator for Medium Fleets (Updated 05/09/14):

The Fleet Average Calculator for Medium Fleets is now available.

Fleet owners utilizing the calculator are advised to first read the User Guide in order to familiarize themselves with the calculator.

The Fleet Average Calculator is an Excel spreadsheet designed to assist fleet owners in calculating their Fleet Average Index and Fleet Average Targets, based on the equipment model year and horsepower input. The calculator allows fleet owners to experiment with different turnover, repower, and retrofit strategies to plan for compliance with the In-Use Off-Road Diesel Vehicle Regulation

Fleet Average Calculator for Large Fleets (Updated 05/09/14):

The Fleet Average Calculator for Large Fleets has been updated to include all compliance years out to 2023.

Fleet owners utilizing the calculator are advised to first read the User Guide in order to familiarize themselves with the calculator.

The Fleet Average Calculator is an Excel spreadsheet designed to assist fleet owners in calculating their Fleet Average Index and Fleet Average Targets, based on the equipment model year and horsepower input.

Statewide Off-road Regulatory Cost / Benefit Model: An updated version the Statewide Off-road Regulatory Cost/Benefit Model has been automated to evaluate multiple fleets in a single program. The model is a Visual Basic module that runs within an Access database and utilizes Access queries. The model is described in detail in Appendix H of the April 2007 Technical Support Document. The zipped file is approximately 15 MB, the uncompressed file is approximately 60 MB but will substantially increase in size as it is used. The output of this model only includes equipment capital costs. [NOTE: This model is computationally intensive and may exceed the limits of a computer's operating system depending on how many vehicles are run.] 

Statewide Off-Road Costs Spreadsheet
: This spreadsheet uses the output from the Statewide Off-Road Regulatory Cost / Benefit Model to calculate total statewide costs. These include reporting, maintenance, and other costs.  .
