tru -- ARB Publishes Q&A for TRU Generator Sets

Posted: 31 Jul 2013 08:51:46
The California Air Resources Board (ARB) has published a Q&A for
transport refrigeration unit (TRU) generator sets (genset) to
answer frequently asked questions about compliance with the TRU
Regulationís requirements for brokers, shippers, receivers,
carriers, and drivers at California port terminals and depots. 

This Q&A answers questions ARB received about who gets a citation
if a noncompliant TRU genset is dispatched at a port terminal or
depot for typical cases of genset ownership.  TRU gensets are
generator sets that are designed and used to provide electric
power to electrically driven refrigeration units of any kind. 
This includes, but is not limited to gen sets that provide
electricity to electrically powered refrigeration systems for
semi-trailer vans and shipping containers.

This Q&A also discusses who is responsible for terminal Operator
Reports, as required under the TRU Regulation.  Port terminals
and depots are responsible for Operator Reports, but may forego
these reports if they make sure all of the ocean carriers that
own TRU gensets submit Operator Reports for the gensets the port
terminal or depot garages, maintains, re-fuels, checks out, and
dispatches.  A terminal is any place where a TRU or TRU gen set
equipped truck, trailer, shipping container, railcar or TRU gen
set is garaged, maintained, operated, or dispatched from,
including a dispatch office, cross-dock facility, maintenance
shop, business, or private residence.

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.
