Toxics Rule Proposal Case Study Air Quality Modeling Data Drive

EPA has placed in the docket a data drive containing certain air quality modeling data files, run 

scripts, and codes that were used for the Toxics Rule proposal for the case studies in the 

Appropriate and Necessary analyses. Information on the air quality modeling performed for this 

rule including a description of the model inputs, emissions, and results can be found in the NonHg Case Study Technical Support Document that is located in the Toxics Rule docket.

The following information is contained on this data drive. All air quality model inputs, outputs,

run scripts, and source code are listed in Appendix A.

EPA will respond to specific requests for subsets of the data or for specific additional inputs and 

outputs of the modeling process, depending on the availability of the data. These and all the 

relevant data and inputs used in the air quality modeling are incorporated into the docket. 

Requests for electronic copies of the air quality modeling data used for this rule should be sent to 

Tyler Fox (fox.tyler@epa.gov).

Appendix A: Modeling Inputs and Outputs

File: emissions.zip

Description: Annual emissions of HAPs by facility and source group. The zipfile contains a 

folder for each facility. Within each facility’s folder is a file called annual_emissions.txt, which

lists annual emissions (tons/year) for each HAP by source group. 

Format of annual_emissions.txt

Column Description

Anchor HAP Integer indicating that HAP is the HAP whose emissions are in the hourly AERMOD input 

emissions files. If the number is 1, then the HAP is the anchor HAP. Otherwise, the number is 

zero

HAP NAME Pollutant name

SOURCE ID AERMOD source identifier

EMISSIONS Annual emissions (tons/year) for HAP and SOURCE ID

URE HAP’s unit risk estimate for cancer

Rfc HAP’s reference concentration for non-cancer effects

ORGANS Text string of numbers to indicate if a HAP affects a particular organ system. A 1 indicates the 

HAP affects the organ system, a 0 indicates it does not. Order of organs are: respiratory, liver, 

neurological, developmental, reproductive, kidney, ocular, endocrine, hematological, 

immunological, skeletal, spleen, and thyroid
