ordiesel -- In-Use Off-Road Diesel Vehicle Regulation Revised Fleet Average Calculator Now Available

Posted: 23 Apr 2013 16:31:36
The revised Fleet Average Calculator and an accompanying user
guide are now available.   The revised calculator allows large
fleets (those with over 5,000 horsepower (hp) affected vehicles)
to evaluate compliance options for the Air Resources Boardís 
In-Use Off-Road Diesel Vehicle Regulationís January 1, 2014,
compliance date only.  Note that this Fleet Average Calculator is
not applicable to small or medium fleets.

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 hp
input.  The calculator allows fleets to experiment with different
turnover, repower, and retrofit strategies to plan for compliance
with the in-use off-road diesel vehicle regulation.

The revised fleet average calculator and its user guide are both
available at
http://www.arb.ca.gov/msprog/ordiesel/documents/documents.htm.
The calculator will be receiving additional updates and
improvements in the future.  If you have any questions, comments,
or other suggestions pertaining to the calculator, please contact
Kyle Goff by phone at (916)-323-1414, or by email at
kgoff@arb.ca.gov.


Background

The regulation for In-Use Off-Road Diesel Vehicles first became
effective under California law on June 15, 2008.  This regulation
is intended to reduce harmful emissions from diesel powered
construction and mining vehicles operating in California that
have propulsion engines that are 25 hp or greater.  Fleets were
required to initially report their off-road diesel vehicles to
ARB in 2009 via DOORS.  In addition, fleet owners are currently
subject to restrictions on unnecessary idling, and some large
fleets will be subject to accelerated replacement/repower
requirements beginning January 1, 2014.

If you have any questions regarding off-road reporting, please
contact the DOORS hotline at (877) 59-DOORS (877-593-6677) or by
email at doors@arb.ca.gov.  For further information about the
off-road diesel vehicle regulation, please visit the off-road
regulation website at: http://www.arb.ca.gov/ordiesel.  For
