tru -- ARB Publishes Updated Guidance for TRUs Using Electric Standby or Hybrid Electric as Compliance Strategy

Posted: 12 Jul 2013 10:43:18
The California Air Resources Board (ARB) has updated its
Regulatory Guidance for Electric Standby and Hybrid Electric
Systems for Alternative Technology transport refrigeration unit
(TRU) compliance strategies. 

If your compliance strategy for meeting the ARBís TRU Regulation
in-use performance standard requirement is electric standby or
hybrid electric, you should download and review the updated
Guidance (see link below).

This guidance includes an explanation of the requirements that
must be met before electric standby or hybrid electric can
qualify as a TRU compliance technology.  For example, to qualify,
the unit must be registered in ARBís Equipment Registration
(ARBER) system, and the unit must be plugged into an electric
power plug at all nonretail pick-up and delivery points in
California when the van is loaded with perishable goods and
during initial cool-down.  Manual recordkeeping is now required
to demonstrate the diesel engine operation has been eliminated at
nonretail delivery and pick-up locations (such as food
manufacturers, packing houses, wholesale and grocery distribution
centers) and TRU engine operation is limited to no more than 30
minutes at retail delivery locations (such as restaurants,
cafeterias, convenience stores, and grocery stores).  GPS
tracking and automated recordkeeping is required on a phased-in
schedule.  This fall, the TRU owner must also update ARBER to
provide the electronic tracking system supplier information.  The
deadline for installing an electronic tracking system with
automated recordkeeping and updating ARBER is December 31, 2013. 
Owners may call the TRU Help Line (1-888-878-2826 or
1-916-327-8737) for assistance with this ARBER update.  

Letters are now being sent to TRU owners that have indicated they
are using electric standby as a compliance option, notifying them
of these requirements.

The updated guidance is available at: 

This Guidance is now also available in Spanish at: 

TRU owners that are using electric standby or hybrid electric as
a compliance option should carefully review this regulatory
guidance to ensure they actually qualify for compliance.  In the
coming months, ARB will be auditing TRU owners that are claiming
to comply by using electric standby or hybrid electric.  This
will include audits to ensure the electric power plugs are being
used at nonretail delivery and pick-up locations and the
recordkeeping and reporting requirements are being met.

ARBís updated regulatory guidance also provides specifications
for businesses interested in providing electronic tracking
systems with automated recordkeeping and reporting.  A list of
electronic tracking system suppliers is available at:

Background:  TRUs are refrigeration systems powered by integral
diesel internal combustion engines designed to control the
environment of temperature-sensitive products that are
transported in trucks, trailers, shipping containers, and
railcars.  The emissions from these units are a source of
unhealthful air pollutants including particulate matter, toxic
air contaminants, nitrogen oxides, carbon monoxide, and
hydrocarbons, that all pose a potential threat to both public
health and the environment. These units often congregate in large
numbers at California distribution centers, grocery stores, and
other facilities where they run for extended periods of time to
ensure their perishable contents remain cold or frozen. These
distribution and loading facilities are often in close proximity
to schools, hospitals, and residential neighborhoods.  In 2004,
the TRU Airborne Toxic Control Measure (ATCM) was adopted by the
Board to reduce diesel particulate matter emissions from TRUs and
TRU gen set engines.  Amendments were adopted by the Board in
November 2010 and October 2011.
