MEMORANDUM

FROM:  	Kenneth Davidson

Assessment and Standards Division, Office of Transportation and Air
Quality

TO:	 	 Docket EPA-HQ-OAR–2014-0827

SUBJECT:	BenMAP-CE Air Quality Modeling Data Files for Estimation of
Supplemental Benefits Analysis to support the Final Phase 2 Heavy-Duty
(HD) Greenhouse Gas (GHG) National Program

The purpose of this memorandum is to transmit BenMAP-CE air quality
modeling data input and configuration files used for the estimation of
the supplemental PM and ozone-related benefits associated with the Final
Phase 2 HD GHG Rule.  When used as input files to the publicly-available
Environmental Benefits Mapping and Analysis Program – Community
Edition (BenMAP-CE), a user will be able to replicate the supplemental
benefits analysis results presented in Appendix 8A of the Regulatory
Impact Analysis for this rulemaking.  The summary files are as follows:

File 1: HDGHG_Phase2_CMAQ_Output_Files.zip

12km ambient PM and ozone air quality CMAQ output data (baseline and
control for 2040)

File 2: HDGHG_Phase2_AirQualityGridFiles_BenMAP.zip

12km ambient PM and ozone air quality grid input data for BenMAP
(baseline and control .aqgx files for 2040)

File 3: HDGHG_Phase2_AirQualityConfigurationFiles_BenMAP-CE.zip

PM and ozone health effects configuration file for BenMAP-CE (.cfgx
files)

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

File 4: BenMAP.exe

BenMAP-CE executable for version 1.1 used to estimate supplemental
health impacts for the final rulemaking analysis

The supplemental benefits analysis is discussed in Appendix 8A of the
Regulatory Impact Analysis.  

 BenMAP-CE v.1.1 is compatible with these files and can be downloaded at
