SUBJECT: Index for Supporting Documentation for the National Scale Immediate 

Receiving Water Model [DCN SE04593]

This document serves as the index for the supporting documentation for the National 

Scale Immediate Receiving Water (IRW) Model, developed as part of the Environmental 

Assessment for the Effluent Limitations Guidelines and Standards for the Steam Electric Power 

Generating Point Source Category (EA Report), Document No. EPA-821-R-15-006 (DCN 

SE04527). The supporting documentation for this model includes the files listed in Table 1.

Attachment 1: CBI_Final Steam 

EA IRW Model - Wildlife and 

Human Health Module -

Comparison Database for EJ 

Cohorts - Option A (CPP) - DCN 

SE04593A1

CBI_Database used to compare the human health module 

results between baseline and Option A specifically for the 

cohorts used in the Environmental Justice analysis (i.e., 

race population cohorts). Generates inputs for the 

Environmental Justice calculation databases. This version 

accounts for the CCR and CPP rulemakings.

results between baseline and Option B specifically for the 

cohorts used in the Environmental Justice analysis (i.e., 

race population cohorts). Generates inputs for the 

Environmental Justice calculation databases. This version 

accounts for the CCR and CPP rulemakings.
