Verification of the Caterpillar DPF for Off-road Equipment. 

The Air Resources Board verified the Caterpillar Diesel
Particulate Filter as a Level 3 Plus passively regenerated
diesel emission control system for use with all off-road
equipment powered by certain off-road diesel engines with model
years between 1996 and 2008.  Approved engines are certified to
a particulate matter emission level equal to or less than 0.2
grams per brake horsepower-hour, are rated to 175 horsepower
through 600 horsepower, and are not equipped with exhaust gas
recirculation systems.  Specific conditions for which the
Caterpillar DPF has been approved may be found in the Executive
Order which will be posted within ten days on the ARB website at
http://www.arb.ca.gov/diesel/verdev/verdev.htm .
