MEMORANDUM FOR THE DOCKET
--------------------------------------------------------------------------------
Subject:	Data and Results for the monetized Health Benefits Analysis completed using BenMAP-CE as part of the Regulatory Impact Analysis for the MATS RTR Proposal 
--------------------------------------------------------------------------------
Date: 	March 14, 2023
EPA has placed into docket number EPA-HQ-OAR-2018-0794, files used to estimate the benefits to human health of reducing concentrations of ozone and PM2.5 as part of the Regulatory Impact Analysis for the MATS RTR Proposal. The assessment was completed using BenMAP-CE version 1.5.8.21.  Health incidence and valuation estimates can be reproduced either by performing individual parameterized runs for a given air quality scenario and year using the BenMAP graphical user interface (GUI) or performing batch runs using scripts.
BenMAP runs were batch processed using command line and a written script. The full set of estimates can be reproduced using the automation script files available in the docket materials, which can be run from the command prompt using the input air quality surface files. See Appendix L of the BenMAP manual for additional details on running BenMAP through the command line and the Estimating PM2.5- and Ozone-Attributable Health Benefits Technical Support Document (TSD) for additional information of selection of health endpoints and concentration-response relationships.
Standard BenMAP folders are included in the docket materials, described below. Script files can be reviewed and modified in a text editor such as Notepad++, which includes comments preceded by "#". Four script files were used for this analysis.:
 ozone_MATS_RTR_proposal_docket.ctlx produces the national level ozone-related health benefits for the scenario years of 2028, 2030 and 2025
 PM_MATS_RTR_proposal_docket.ctlx produces the national level PM-related health benefits for the scenario years of 2028, 2030 and 2025
 ozone_MATS_RTR_proposal_annual_docket.ctlx produces the national ozone-related health benefits valuation results for each year from 2028-2037
 PM_MATS_RTR_proposal_annual_docket.ctlx produces the national PM-related health benefits valuation results for each year from 2028-2037

The script file can be reviewed and modified in a text editor such as Notepad++, which includes comments preceded by "#". Prior to running the script from the command line, a number of subdirectory pointers within the automation code must be set to where the user has placed the input files and results directories for outputs. Imbedded notes within the automation code highlight the pointers which must be updated, which appear near the beginning of the script file. Once pointers have been updated and the required input files have been placed in the appropriate subdirectories (see below), then the script run is initiated with the below commands from the command prompt: 
 Direct to the location where the BenMAP program is located (e.g., "cd\program files (x86)\BenMAP-CE") and hit Enter
 Direct the command line prompt to the script file (e.g., start/wait "" "C:\program files (x86)\benmap-ce\benmap.exe" "C:\[INSERT FILE LOCATION}\ ozone_MATS_RTR_proposal_docket.ctlx ")

In order to run the automated script, make sure that the following subdirectories have been created, include the necessary input files, and the script has been edited to their location:

 "Inputs" Containing the air quality grid .csv (or .xlsx) files
 "AQG" Will be the location of output .aqgx air quality gridded surface files
 "CFG" Containing the BenMAP configuration file used as the basis for generating risk estimates, e.g., Ozone_2028.cfgx
 "APV" Contains BenMAP aggregation and pooling file which allows .apvx and .cfgrx reports containing the risk estimates to be generated, e.g., Ozone_2028.apvx
 "Reports" Will be the location of exposure output .csv files. Please add this folder to your intended file location.
 "Results" Will be the location of exposure output .cfgrx and .apvrx files. Please add this folder to your intended file location.
