MEMORANDUM

FROM:  	Kenneth Davidson

Assessment and Standards Division, Office of Transportation and Air
Quality

TO:	 	 Docket EPA-HQ- OAR–2011–0135

SUBJECT:	BenMAP Air Quality Modeling Data Files for Estimation of
Benefits for the Final Tier 3 Rulemaking

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 benefits associated with the Tier 3 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
benefits analysis results presented in the RIA for this rulemaking.  The
summary files are as follows:

File 1: Tier3_CMAQ_Output_Files.zip

12km ambient PM and ozone air quality CMAQ output data (baseline and
control for 2018 and 2030)

File 2: Tier3_AirQualityGridFiles_BenMAP.zip

12km ambient PM and ozone air quality grid input data for BenMAP
(baseline and control .aqg files for 2018 and 2030), including control
files where California-related air quality changes in the control
scenario have been held constant to levels in the baseline scenario

File 3: Tier3_AirQualityConfigurationFiles_BenMAP.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 4: BenMapUS.exe

BenMAP executable for version 4.0.65 used to estimate health impacts for
the final rulemaking analysis

The benefits analysis is discussed in Section VIII of the preamble and
Chapter 8 of the Regulatory Impact Analysis.  

 BenMAP v. 4.0 is compatible with these files and can be downloaded at
