The California Air Resources Board on Wednesday, July 1, announced the delay of two compliance deadlines for the Transport Refrigeration Unit (TRU) Airborne Toxic Control Measure (ATCM):

  • The TRU registration and operator report requirements deadline for California-based TRUs has been extended until July 31 — previously delayed from Jan. 31 until March 16. Enforcement of the registration requirements will begin in August; and
  • The deadline for meeting the Low-Emission TRU (LETRU) In-Use Performance Standards for 2001 and older TRU engines has been delayed until Dec. 31 — previously delayed from Dec. 31, 2008, until July 16. Enforcement of the in-use performance standards will begin in January 2010 for all model-year 2002 and older engines.
  • CARB says it is extending these deadlines because as the close of the grace period approached, it became clear that several thousand TRUs were not in position to comply by mid-July because of lack of timely action by TRU owners, higher costs for compliance than originally anticipated, some retrofit systems not becoming available until this past May, tightening of credit, and longer lead times for delivery of systems.

    CARB says that given these factors, it determined that a two-phase enforcement schedule would allow for more complete registration and provide some additional time for pre-2002 TRUs to come into compliance in an orderly manner. CARB says lead times are typically three to four months for most compliance technologies, so orders should be placed by Sept. 1 in order to ensure compliance by Dec. 31.
