California agency studies reefer unit rule
The California Air Resources board, in response to questions about 2003 transport refrigeration units and TRU generator sets, will enforce the January compliance deadline, but soon will consider an option for meeting this standard.
On Oct. 8, CARB announced that affected owners without the compliance technology should order now to ensure delivery time by deadline. The TRU Airborne Toxic Control Measure requires 2003 engines be retrofitted to meet the Ultra-Low-Emission TRU in-use standards by Dec. 31. The rule requires a Level 3 verified diesel emissions control system, which reduces diesel particulate matter by at least 85 percent.
At its Nov. 18-19 meeting, CARB will consider a proposal to allow a less stringent compliance standard proposal for these products because of limited availability of Level 3 control systems. It would provide the option of using the ULETRU in-use standard or the less stringent low emission in-use standard or LETRU. The latter would require Level 2 Verified Diesel Emissions Control Strategies, which would reduce diesel particulate matter by at least 50 percent.
The board will also consider a compliance option of replacing the 2003 engine with a later year model. If approved, it would demand ULETRU emission standards be met by Dec. 31st of the seventh year after the replacement engine’s model year.

The board will receive comments on the proposals until noon Nov. 17 electronically at www.arb.ca.gov/lispub/comm/bclist.php. You may also submit comments by writing Clerk of the Board, Air Resources Board, 1001 “I” St., Sacramento, CA, 95814.
