tru -- ARB Publishes Regulatory Guidance for Electric Standby and Hybrid Electric Compliance Options for TRUs (reefers)

Posted: 16 Nov 2012 09:09:18
The California Air Resources Board (ARB or Board) has posted
Regulatory Guidance for Electric Standby and Hybrid Electric
Systems for Transport Refrigeration Units (TRU). 

This guidance document explains requirements for the use of
electric standby and hybrid electric systems (together referred
to as E/S) as an option for compliance with Californiaís TRU
regulations' in-use performance standards.  A TRUís compliance
can be maintained beyond seven years if an E/S system is
integrated into the equipment and used within the guidelines for
an Alternative Technology.  Also provided are specifications for
businesses interested in providing electronic-tracking systems
(ETS) to affected TRU owners.

These requirements were added in the 2011 Amendments.  Manual
recordkeeping is required, beginning November 14, 2012.  ETS
includes automated monitoring, recordkeeping, and reporting, with
GPS tracking, and is required beginning January 1, 2013, for 50
percent of a fleetís TRUs that are complying with the TRU
Regulationís in-use standards by using E/S systems.  The
remaining 50 percent of a fleetís E/S-equipped TRUs that are
complying with the in-use standards by using E/S must be equipped
with ETS by January 1, 2014.  TRUs using E/S must be registered
in ARBER to qualify as compliant.

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.
