		Office of Transportation and Air Quality

TO:		Docket EPA-HQ-OAR-2005-0161-DRAFT-2902

DATE:		January 13, 2010

The purpose of this memorandum is to transmit data files which were used
in the air quality modeling analyses for the final renewable fuel
standard rule.  The air quality modeling analyses are discussed in
Section VI of the preamble, Chapter 3 of the Regulatory Impact Analysis
(RIA) and in the Air Quality Modeling Technical Support Document. 
Information on the inventories is also discussed in Chapter 3 of the
RIA.  Following is a list of the information contained on the enclosed
disc.
