If you are updating a TRU or TRU generator set registration which was registered in ARBER before September 30, 2022, you will see a date of 01/01/0001. You must update this date to complete updating the application.
I am the owner of this equipment (or employee of the owner).
This is the default for this field. If you are not the registered owner of this transport refrigeration unit (TRU) or TRU generator set, see below. "Owner" is defined in the TRU Airborne Toxic Control Measure (ATCM).
I am entering this information for the Owner and I have a Third Party Agreement in place (Consultant or Lessee).
Select this option if you are not the registered owner. If you are not the registered owner of this equipment you must have a third-party agreement in place in order to enter information for the registered owner.
Users who are entering information for the registered owners are known as "delegates." Delegates must provide certification information to the registered owner of the equipment. Third party agreement forms are available on the TRU forms page. These forms must be received by CARB 10 days prior to registering information on the equipment.
Owner's Tax Identification Number
Required only if you are not the owner of this equipment. Enter the Tax-ID/Federal Employer Identification Number (EIN) belonging to the owner of the equipment. This EIN must match the owner EIN on the third-party agreement. This field must be entered in the proper format.
If you are entering TRU information for the registered owner, you must provide the owner's Federal EIN. ARBER uses this number to link the equipment being registered to the owner.
Federal EINs are provided to CARB through the third-party agreement forms. These forms must be received by CARB 10 days prior to the time the delegate enters the information for the owner.
