Proposed amendments to CARB's In-Use Off-Road Diesel-Fueled Fleets Regulation

The California Air Resources Board (CARB) is currently working on potential amendments to the In-Use Off-Road Diesel-Fueled Fleets Regulation. The current Regulation requires fleets to meet their performance requirements, report and label their equipment, and limit idling to 5 minutes among other requirements. This Regulation is applicable to all self-propelled off-road diesel vehicles that are 25 horsepower or greater. Typically, this is equipment used in construction, mining, industrial operations, and other industries.

These amendments are expected to lower emissions of criteria pollutants (oxides of nitrogen) and toxic air contaminants (particulate matter), but its provisions may impact disadvantaged communities. We would like to involve community groups in the amendment process so that we can better understand how this regulation may impact California communities, and get feedback on how CARB can minimize any negative impacts and maximize the benefits.

The potential amendments thus far include but are not limited to: an operational backstop on the oldest equipment, extension of the Adding Vehicles Provision which limits the equipment a fleet can add, low-use exemption modification, requirements for Prime Contractors and Public Works Awarding Bodies, and requirements for fleets to use Renewable Diesel. The next virtual workshop will be on December 14, 2021 where CARB will present a more refined and comprehensive proposal for the potential amendments to the Regulation that builds upon the concepts presented at the kick-off workshop in May 2021 and workgroups that followed. A portion of the workshop will also be focused on the off-road inventory which will cover data sources and methodology for the emission inventory, including population, activity, emission rates and more.
