tru -- Model Year 2003 Engines Must Comply by December 31, 2010
Posted: 06 Oct 2010 16:17:31
Model year 2003 TRU engine owners should make compliance decisions now and place orders for compliance technology now to ensure compliance by December 31, 2010. The California Air Resources Board’s (ARB) Transport Refrigeration Unit (TRU) Airborne Toxic Control Measure (ATCM) currently requires model year (MY) 2003 engines to meet the Ultra-Low-Emission TRU (ULETRU) in-use standards by December 31, 2010. The ULETRU standard can be met by retrofitting with a Level 3 verified diesel emissions control system (VDECS) that reduces diesel particulate matter by at least 85 percent. ARB has proposed amendments to the TRU ATCM, which will be considered by the Board on November 18, 2010. One of the proposed amendments affects MY 2003 TRU engines and would allow them to comply with the in-use standard requirements by meeting either the ULETRU in-use standard, as described above, or as an option, by meeting the less stringent LETRU in-use standard. The LETRU in-use standard can be met by retrofitting with a Level 2 VDECS that reduces diesel PM by at least 50 percent. The proposed optional LETRU compliance path is being offered due to limited availability of Level 3 control systems. Some MY 2003 TRU owners have expressed uncertainty about the need to comply because of the pending Board decision. To clarify, the in-use requirements for MY 2003 TRU engines were approved in February 2004 and became effective December 2004. There will be no enforcement delay or compliance extension for MY 2003 engines. MY 2003 TRU engines must meet the in-use performance standard by December 31, 2010. ARB will enforce the in-use standards for MY 2003 engines starting early 2011 and will accept either ULETRU (Level 3 retrofit) or LETRU (Level 2 retrofit). Another compliance option would be to replace the MY 2003 engine with a 2004 or later MY engine. However, if this engine replacement option is chosen, the ULETRU emission standards would have to be met by December 31st of the seventh year after the replacement engine’s model year (or effective model year in the case of a prior-tier engine). As TRU Advisory 10-19 indicates, MY 2003 owners should make compliance decisions now and place orders for compliance technology now to ensure compliance by December 31, 2010. TRU Advisory 10-19 is available at: http://www.arb.ca.gov/diesel/tru/advisories.htm VDECS that may be used to comply with the in-use standards are listed at the TRU Website in the bottom section at: http://www.arb.ca.gov/diesel/tru.htm If you have any questions, please contact the TRU Help Line at 1-888-878-2826 or call 916-445-5516.
