Subject: Input data for analyses associated with Chapter 3/Appendix B and Appendix A and of the PM NAAQS Policy Assessment. 
Date: February 2020

Chapter 3/Appendix B data files
	The following files (found in the folder titled "Chapter 3 appendix B data") were used to calculate analyses and develop figures and tables associated Chapter 3 and Appendix B of the Policy Assessment. In some files, the data is a product of statistical analyses using statistical software programs R Software and SAS, but could be generated using any type of statistical software. For illustration purposes, the files below were imported into Tableau software (Tableau 2019.3). The table below states the file name and associated figures within Chapter 3 or Appendix B of the Policy Assessment. 
	The file "Base_analysis_file.xlsx" was developed by EPA staff, using data from multiple sources, including published papers referenced in Chapter 3 of the Policy Assessment, U.S. 2015 Census Data and 2016 Statistics Canada data (see section B.4), as well as Air Quality information accessed from the Air Quality System (AQS) and found in the following file names: 

          "24hrDV_wPop_ALL_COUNTIES_1999_2017_Special_POP.xlsx"; and  
          "AnnualDV_wPop_ALL_COUNTIES_1999_2017_Special_POP.xlsx" 

This file ("Base_analysis_file.xlsx") serves as the main file from which most analysis files in the table below were derived.

Base_analysis_file.xlsx
This file is the main file used for most analyses below.  The file contains information related to effect estimates, design values, and population data. 
Figure 3-7
Monitored.Mean.Percentile.xlsx
File contains mean/median, and where available, 10th and 25th percentile study concentration data for monitored studies.
Figure 3-8
Modeled.Mean.Percentile.xlsx
File contains mean/median, and where available, 10th and 25th percentile study concentration data for modeled studies.

1. "Base_analysis_file.xlsx"
2. Population_percentile_and_pseudo_dv.xlsx
Population_percentile_and_pseudo_dv.xlsx is derived from "Base_analysis_file.xlsx" and contains data related to the percentile of population associated with a study average maximum pseudo design value.
Table B-7 and Table B-8
1.Epi study info.xlsx;
2.total population by study by pop by county.xlsx; 
3.total population by study by pop by county with DV.xlsx
These files were derived from the "Base_analysis_file.xlsx" file and contain information related to exposure years, design values and population, by study.
Figure B-3, Figure B-4
1. Study percentiles.xlsx
2. Population_percentile_and_pseudo_dv.xlsx
These files were derived from the "Base_analysis_file.xlsx" and contain information related to design values and the percentile population related to the percent of population.

File related to analyses associated with regulatory versus non regulatory monitor analysis






Appendix A data files
	The following files (Found in the "Appendix A emails and data files" folder) are referenced in Appendix A. All files are attached to an email, except for "downscaler_12US2.ann.avg.rdata," and an explanation of the files is present within the respective email. The "downscaler" files titled "downscaler_12US2.ann.avg.rdata"  were developed in terms of daily average Downscaler predictions on a national grid following methods described in Appendix C of the Policy Assessment.
