Re: Transport Refrigeration Units Rulemaking -- Support
Dear Board Members:
	Coalition for Clean Air supports the Proposed Amendments to the
Airborne Toxic Control Measure for In-Use Diesel-Fueled Transport
Refrigeration Units (TRU) and TRU Generator Sets, and Facilities
Where TRUs Operate that are on the agenda for your September 23
Board Hearing. These strengthening amendments to the current rule
are important to reduce diesel particulate matter (PM) emissions
and resulting health risk from diesel-powered TRUs.
	The 2010 and 2011 amendments have not reduced emissions as much as
expected, in large part because of growing sales of units with less
than 25 horsepower engines. The proposed amendments would close
that loophole and establish a transition to zero-emission engines
for truck TRUs. This transition will reduce cancer risk to
individual residents and off-site workers near facilities where
TRUs operate, including those located in and near disadvantaged
communities; improve air quality; provide GHG emission reductions
(including the powerful short-lived climate pollutants
hydrofluorocarbons and black carbon) needed to combat climate
change; and reduce non-cancer health impacts such as premature
deaths, hospital visits for cardiovascular and respiratory
illnesses,  and emergency room visits for asthma, especially in
sensitive receptors including children, the elderly, and people
with chronic heart or lung disease. 
	Because of these benefits, we urge the Board to vote for the
amendments today and bring them back for final adoption as soon as
possible. In addition, we urge you to quickly take the next step,
which is to also move all trailer and other TRUs to zero-emission
operation.
Respectfully,
 
Bill Magavern
Policy Director
