MEMORANDUM

FROM:  	Kenneth Davidson

	   	Assessment and Standards Division

TO:	 	 Docket EPA-HQ-OAR-2010–0799

SUBJECT:	BenMAP Air Quality Modeling Data Files for Estimation of Health
Impacts Associated with the Final Model Year 2017-2025 Light-Duty
Greenhouse Gas Rule

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 final Model Year
2017-2025 Light-Duty Greenhouse Gas Rule.  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 2030) 

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: BenMAPv4.0.43.zip

BenMAP v. 4.0.43 executable file (.exe)

The health impacts analysis is discussed in Section III.H of the
preamble and Chapter 6 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
