ordiesel -- Off-Road Regulation Update

Posted: 15 Dec 2009 16:53:59
This notice is to inform fleets that all of the provisions of The
Air Resources Board’s (ARB) In-Use Off-road Diesel Vehicle
Regulation (off-road regulation), including the March 1, 2010,
compliance requirements for large fleets, are unchanged and
remain in effect. 

ARB held a public meeting on December 9, 2009, to receive an
update on implementation of the Truck and Bus Rule and to hear a
brief update regarding economic indicators related to the
off-road regulation.  The Board directed its staff to return in
April 2010 with a new provision for the Truck and Bus Rule that
would provide truck fleets more flexibility in cleaning up their
diesel emissions.  The Board also directed staff to report back
at the same time with a further assessment of off-road vehicle
emissions, and an evaluation of a projection of off-road vehicle
emissions that was prepared by the Associated General
Contractors. The Board’s action does not affect the
implementation of the In-Use Off-road Diesel Vehicle Regulation. 


The off-road regulation required reporting of all off-road
diesel vehicles by August 1, 2009.  Fleets that did not report by
the deadline should do so as soon as possible.  Although the
deadlines for all fleets are past, ARB has extended an informal
grace period so that fleets may report their vehicles late
without penalty. Fleets that self-report will not face
enforcement action if they report all of their vehicles prior to
January 1, 2010 (for large and medium fleets) and March 1, 2010
(for small fleets).  For further information, please see our
updated Reporting Enforcement Advisory at
