CARB Off Road Reporting: Due by March 1st

For each annual report, fleets must report all changes made to the fleet including updated contact information.

Fleet must submit engine hour meter readings for vehicles reported as "Low-Use" vehicles, or vehicles used for agricultural operations 51-99% of the time (if applicable), and submit the Responsible official Affirmation of Reporting (ROAR) form. CARB provides the e-ROAR (electronic ROAR) as a convenience for fleet.

For additional guidance on how to submit an annual report, review the DOORS User Guide How to Submit an Annual Report and Electronic ROAR.

Fleets that do not meet the target emissions by December 31 of each year, must retire 10% of fleet's horsepower as it was at Dec. 31. The Permanent Low Use exemption is available to meet the 10% requirement but be careful. Once declared Permanent Low Use, the unit cannot come back into the fleet for normal use. It may only be used for 200 hours per year, and the designation is permanent. Fleets must report Low Use hours annually during the reporting period.

By the years 2023-2024, the accumulated fleet reduction credits for most fleets will have expired. The Target Emissions Levels will drop significantly. Most fleets will have to have a Tier 4 Final engine for every Tier 3 engine in the fleet in order to meet the emissions targets—no Tier 1 or Tier 2 engines can be included in the emissions calculations to meet the requirements. Those older engines will have negative effects on compliance.

UCON and our sister associations are attempting to work with CARB Staff to find some relief from these stringent requirements. At present we are in early stages of discussions. We will provide additional information to our members as the process unfolds.
