tru -- ACTION REQUIRED – Verify Your TRU and TRU Gen Set Compliance Status in ARBER

Posted: 14 Sep 2012 11:09:17
Data for transport refrigeration units (TRU) and TRU generator
sets (gen set) collected through the Air Resources Board
Equipment Registration (ARBER) program has been updated with
manufacturer information. 

Serial numbers for registered TRUs and gen sets - model year 2006
and newer - have been matched with serial numbers supplied by
manufacturers. This updated data has revealed potentially
miss-keyed information.  In some instances this created
conflicting information that requires fleet manager attention.

Corrections to individual ARBER registrations may be necessary.

If a unit’s serial number provided by the registrant does not
match the serial number provided by the manufacturer, the TRU or
gen set status may have been changed from “compliant” to “pending
verification.” This has occurred to many applications and
requires fleet managers to assure the accuracy of their supplied

What needs to be done?

Fleet managers must log into ARBER and check to see if any
previously compliant TRUs or gen sets now have a “pending
verification” status.  Fleet managers with large numbers of units
registered in ARBER may click on the “Reports” tab and download a
complete list of their units in PDF or CSV format. 

If the compliance status for a unit is found to be “pending
verification”, the unit’s serial number should be double-checked.
Corrections may be submitted through the TRU Help Line at
1-888-878-2826.  Photos of the unit label with serial number may
need to be submitted.  ARB staff is working with manufacturers to
eliminate the pending-verification status for those cases where a
valid serial number was entered.

Why is this Important?

This correction will be important to “for-hire” common carriers
that will need to show that their TRUs are compliant in order to
transport perishable goods on California highways.  In addition,
the in-use compliance date may be affected by these corrections.

Beginning January 1, 2013, freight brokers, forwarders, shippers,
or receivers will be required to only hire or contract with
carriers that can show they can dispatch TRUs compliant with
California’s in-use performance standards.  The business entity
that arranges, hires, or contracts with carriers must require
that their carriers only dispatch TRU-equipped trucks, trailers,
shipping containers, and railcars or gen sets that comply with
the California’s in-use performance standards, if they travel on
the state’s highways or railways.  Carriers will need to provide
proof-of-compliance to the hiring business entity before they can
be hired.  One way to show compliance is to be on ARB’s “100
Percent-Compliant Carrier List.”

Carriers that have registered TRUs in ARBER that are all
compliant with the TRU Regulation’s in-use standards will be
listed on ARB’s “100 Percent-Compliant Carrier List.”  Freight
brokers, freight forwarders, shippers and receivers may look up a
carrier by their company name or U.S. DOT motor-carrier number. 
They may also query ARBER for a complete list of 100
Percent-Compliant Carriers, or narrow the list to a city, county,
or state/province.  The beta test version of the “100
Percent-Compliant Carrier List” is at: 

Carriers are encouraged to examine the list and act now to clear
up any discrepancies in their registration information.  Many
carriers still need to enter their U.S. DOT Motor Carrier Numbers
in ARBER.  Take action now to assure good standing when the new
compliant-only hiring requirement goes into effect on January 1,

Carriers based outside of California wishing to be placed on the
list, should register their TRUs and gen sets in ARBER.  ARBER
will check the registration information before issuing a
compliance certification.  Registrants should be careful to enter
complete and accurate information.

In addition, when a TRU’s or TRU gen set’s compliance information
changes, the carrier must update ARBER as soon as possible to
assure current information is used to determine compliance
status.  For example, when an owner takes steps to bring a unit
into compliance, they need to update ARBER to reflect that
change.  The 100 Percent-Compliant Carrier List is updated in
real time and is current at the time of look-up or download.

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.
