MEMORANDUM

FROM:  	Kenneth Davidson

	   	Assessment and Standards Division

TO:	 	 Docket EPA-HQ-OAR-2005-0161-DRAFT-2903

SUBJECT:	BenMAP Air Quality Modeling Data Files for Estimation of Health
Impacts Associated with the Mandated Renewable Fuel Volumes

The purpose of this memorandum is to transmit BenMAP air quality
modeling data input and configuration files used for the estimation of
PM and ozone-related health impacts associated with the mandated
renewable fuel volumes of the RFS2 FRM.  When used as input files to the
publicly-available Environmental Benefits Mapping and Analysis Program
(BenMAP), a user will be able to replicate the health impacts analysis
results presented in the RIA for this rulemaking.  The summary files are
as follows:

File 1: BenMAP_AirQualityGrids.zip

12km ambient PM and ozone air quality grid input data for BenMAP
(baseline and control for 2022) 

File 2: BenMAP_Configurations.zip

PM and ozone health effects configuration file for BenMAP (.cfg files)

PM and ozone health effects aggregation, pooling, and valuation file for
BenMAP (.apv files)

File 3: BenMAP_Executable.zip

BenMAP v. 3.14 executable file (.exe)

The health impacts analysis is discussed in Section VIII of the preamble
and Chapter 5 of the Regulatory Impact Analysis.  

 BenMAP v. 3.0 is compatible with these files and can be downloaded at
http://www.epa.gov/air/benmap/download.html
