MEMORANDUM FOR THE DOCKET
--------------------------------------------------------------------------------
Subject:	Input data for the overall risk assessment and the at-risk analysis completed using BenMAP-CE as part of the PM NAAQS Reconsideration
--------------------------------------------------------------------------------
Date: 		October 12, 2021
EPA has placed into docket number EPA-HQ-OAR-2015-0072, files used in generating the mortality estimates for the overall risk assessment and the at-risk analysis completed using BenMAP-CE as part of the PM NAAQS Reconsideration. The assessment was completed using BenMAP-CE version 1.5.8.11. Health incidence estimates can be reproduced either by performing individual parameterized runs for a given air quality scenario and set of urban study areas 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.
The standard BenMAP folders are included in the docket materials, however in some cases there are two sub-folders distinguishing files for the "Overall Risk Assessment" and "At-Risk Analysis." 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 to the script file (e.g., "C:\ PM_NAAQS_RA.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 files
 "AQG" Will be the location of output .aqg air quality surface files
 "CFG" Containing the BenMAP configuration file used as the basis for generating risk estimates, PM_NAAQS_HHRA.cfgx
 "APV" Contains BenMAP aggregation and pooling file which allows reports containing the risk estimates to be generated, PM_NAAQS_HHRA.apvx
 "Reports" Will be the location of output .csv files
 "Results" Will be the location of output .cfgrx and .apvrx files
