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
