Compliance with the California Air Resources Board Transport Refrigeration Unit regulation’s in-use performance standard now is required for any pre-2003 TRU operating in California, regardless of where the TRU is based.
CARB says inspectors will issue citations to owners of California-based TRUs that have failed to register or affix identification numbers to their TRUs, with penalties up to $500 per violation. Registration is voluntary for TRUs based outside of California.
