Off Road Solutions

Heavy-duty, off-road diesel equipment used in construction, mining and industrial operations is now subject to CARB regulation.  This includes:  wheel loaders, crawler tractors, dozers, motor graders, excavators, skid steers, backhoes, forklifts, and airport ground support equipment.
The regulation is divided into small, medium, and large fleets based on fleet ownership and total fleet horsepower.    

Compliance Calendar *

The compliance calendar for the Off-Road regulations was changed in December 2010

• A four year delay from the original timeline for all fleets, making the first compliance deadline
  January 1, 2014, for large fleets (over 5,000 hp), January 1, 2017, for medium fleets (2,501-5,000
  hp), and January 1, 2019, for small fleets (2,500 hp or less).
• A dramatic reduction and simplification in the annual requirements for fleets, and fleet average
  structure. Fleets now have only one fleet average target to meet based on their NOx emissions;
  if they cannot meet the fleet average target, they are required to clean up 5 to 10 percent of their
  horsepower annually, as opposed to the previous requirement of 28 to 30 percent.
• Making exhaust retrofits no longer mandatory.
• Raising the low use threshold to 200 hours per year instead of 100 hours
• Overall, staff estimates that these amendments reduce the compliance costs by more than 95
  percent during the first five years and more than 70 percent during the entire span of the
  regulation, compared to the regulation before the amendments.

What do I need to do now?
The off-road regulation as initially adopted requires reporting and labeling, limits unnecessary idling, and
requires disclosure of the regulation upon vehicle sale. These requirements are not affected by the
December 2010 amendments, and enforcement actions for these requirements are ongoing, with fines of
up to $10,000 per day possible for each vehicle that is in violation.

If a fleet has not done so already, it should report all applicable vehicles to ARB as soon as possible and
label its vehicles appropriately. Fleets should also comply with the five-minute idling limit and maintain a
written idling policy as required. When selling an affected vehicle, the seller should notify the vehicle
buyer of the regulation.
