Off-Road Vehicles

The California Air Resources Board (CARB) regulates mobile emission sources for certain UCLA vehicles.  

 

Under the Off-Road Diesel-Fueled Fleets Regulation (Off-Road Regulation), UCLA reports inventory annually of all self-propelled off-road diesel vehicles 25 horsepower and greater. These include: 

 

  • Lawn mowers
  • Tractors
  • Backhoes
  • Vacuum sweepers  

In order to economically and feasibly reduce criteria pollutants, the Off-Road Regulation requires replacement, retirement, and/or retrofit of older vehicles in a phased approach. Vehicles subject to the Off-Road Regulation require special CARB labeling and are subject to idling limits.

 

Under the Large-Spark Ignition (LSI) Regulation, facilities are required to report off-road large spark-ignition vehicles with 25 or more horsepower and greater than 1-liter displacement. These include: 

 

  • Forklifts (electric Class 1 or 2 rider truck or LSI engine-powered Class 4 or 5 rider truck)
  • Sweepers/scrubbers (electric or LSI industrial floor cleaning equipment) 

While UCLA is not currently subject to CARB’s LSI regulation, Environmental Compliance annually assesses vehicle inventory to ensure continued UCLA compliance. 

 

EH&S should be notified as soon as possible when new and/or replacement vehicle purchases that may fall under these regulations are planned, and when vehicles are retired. 

All regulated vehicles are required to be registered through CARB’s Diesel Off-Road Online Reporting System (DOORS) within 30-days of operation. 

Registering a New Diesel Off-Road Vehicle 

 

  1. The requesting department provides EH&S the following information:

    1. Vehicle manufacturer, model, model year, serial number 

    2. Engine manufacturer, model, model year, serial number 

    3. Vehicle specifications sheet 

  2. EH&S registers the vehicle in the State system. The system generates an Equipment Identification Number (EIN).  
  3. EH&S provides the EIN to the requesting department along with CARB-mandated labeling instructions. 
  4. The requesting department works with the UCLA Sign Shop (or equivalent) to produce and affix the labels to the new equipment. 
Reporting a New Large-Spark Ignition (LSI) Vehicle 

 

  1. The reporting department provides EH&S the following information: 

    1. Vehicle manufacturer, model, model year, serial number 

    2. Engine manufacturer, model, model year, serial number 

    3. Type of fuel (gasoline, propane, CNG fuel) 

    4. Vehicle specifications sheet 

  2. EH&S determines if the vehicle requires registration in the State system. If so, EH&S registers the vehicle in the State system. The system generates an Equipment Identification Number (EIN). 

  3. EH&S provides the EIN to the reporting department along with CARB-mandated labeling instructions. 

  4. The requesting department works with the UCLA Sign Shop (or equivalent) to produce and affix the labels to the new equipment.
