RE: REQUEST FOR AUTHORIZATION ACTION PURSUANT TO CLEAN AIR ACT 

SECTION 209(e) FOR 2011 AMENDMENTS TO THE AIRBORNE TOXIC 

CONTROL MEASURE FOR IN-USE DIESEL-FUELED TRANSPORT 

REFRIGERATION UNITS (TRU) and TRU GENERA TOR SETS AND 

FACILITIES WHERE TRUs OPERATE 

Dear Administrator McCarthy: 

In 2011, the State of California Air Resources Board (CARB) approved amendments to 

California's Airborne Toxic Control Measure for In-Use Diesel-Fueled Transport 

Refrigeration Units (TRU) and TRU Generator Sets and Facilities Where TRUs Operate. 

These amendments primarily provide owners of 2001 through 2003 model year (MY) 

TRU engines that complied with applicable Low-Emission TRU (LETRU) in-use 

performance standards by specified compliance deadlines a one- or two-year extension 

from the more stringent Ultra-Low Emission (ULETRU) in-use performance standards, 

clarify manual recordkeeping requirements for electric standby-equipped TRUs and 

ultimately require automated electronic tracking system requirements for such TRUs, 

and address other issues that arose during the implementation of the regulation. 

I am writing to request that the United States Environmental Protection Agency take 

appropriate authorization action on GARB's 2011 amendments to this regulation. 

Enclosed is an Authorization Support Document that includes a description of the 

adopted 2011 amendments and our analysis and rationale for granting the requested 

actions. 

The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. 

For a list of simple ways you can reduce demand and cut your energy costs, see our website: http://www.arb.ca.gov.
