MEMORANDUM

TO: Steam Electric Point Source Category ELG Rulemaking Record 

FROM: Jill Lucy, ERG

DATE: September 29, 2015

SUBJECT: Proximity Analysis Methodology (DCN SE04478)

ERG supported the U.S. Environmental Protection Agency (EPA) in the development of 

final effluent limitations guidelines and standards (ELGs) for the Steam Electric Power 

Generating Point Source Category (40 CFR Part 423). ERG completed environmental 

assessment (EA) analyses to evaluate environmental and human health impacts under current 

(i.e., baseline) discharge practices and potential improvements associated with the regulatory 

options (Options A, B, C, D, and E).

1 This memorandum documents the methodology and 

resources used in the EA for identifying surface waters that receive discharges of the evaluated 

waste streams and are located in close proximity to the following sensitive environments:

 Impaired waters.

 Fish consumption advisories.

 Drinking water intakes.

 Public wells.

 Sole-source aquifers.

 Great Lakes watershed.

 Chesapeake Bay watershed.

 Threatened and endangered species habitats.

The methodology used to identify sensitive environments is the same used for the 

proposed steam electric ELGs. See the April 13, 2013 ERG memorandum, “Proximity Analyses 

Methodology” (DCN SE03575) for further details on impaired waters, fish consumption 

advisories and drinking water intakes. This memorandum documents updates made for the final 

steam electric EA proximity analyses and the resources ERG developed to complete the 

analyses.

 

1 During development of the final rule, EPA decided not to base the final rule on Option F for existing sources due primarily to 

the high cost of that Option, particularly in light of the costs associated with other rulemakings expected to impact the steam 

electric power generating industry (see Section VIII.C.1 of the preamble). As a result, EPA chose not to conduct particular 

analyses for Option F to the same extent that it did for some of the other options considered.

ERG performed quantitative analyses under two separate industry baseline scopes: 

1. The “With CCR” scope accounts for the Coal Combustion Residuals (CCR) rulemaking: 

222 immediate receiving waters included in the proximity analysis (195 steam electric 

power plants). See the EA Report for more details. 

2. The “With CCR and CPP” scope accounts for both the CCR rulemaking and the Clean 

Power Plan [Clean Air Act Section 111(d)]: 172 immediate receiving waters included in 

proximity analysis used (148 steam electric power plants). See Appendix I of the EA 

Report for more details.

1.0 DATA SOURCES

ERG conducted the proximity analyses for impaired waters, fish consumption advisories, 

and drinking water resources using Esri ArcGIS Desktop software and NHD Plus-indexed 

geographical information system (GIS) datasets that document the location of the sensitive 

environments. ERG created a user-defined buffer zone around each immediate receiving water 

discharge point to identify those located in close proximity to sensitive environments. Table 1 

presents the user-defined buffer zones and GIS datasets used for each type of sensitive 

environment. See the April 13, 2013 ERG memorandum, “Proximity Analyses Methodology”

(DCN SE03575) for further details on this data source and the steps ERG completed to identify 

immediate receiving water discharge points and proximity to sensitive environments.

For the Great Lakes watershed and Chesapeake Bay watershed, ERG identified steam 

electric power plants that discharge into these watersheds using the database, Final Steam EA 

Proximity Analysis - Great Lakes and Chesapeake Bay Watershed Boundaries GIS (DCN 

SE04548). This is a geodatabase representing watershed segments within the Great Lakes 

watershed and the Chesapeake Bay watershed. ERG used this geodatabase to determine which 

steam electric power plants in the EA scope (both “with CCR” and “with CCR and CPP”) 

discharge to these watersheds. ERG obtained the Chesapeake Bay data from the Chesapeake Bay 

Regional Watershed Model (CBRWM) and edited the geodatabase to remove watershed 

segments from the adjacent states of New York, Pennsylvania, Maryland, West Virginia, 

Delaware, Virginia, North Carolina, and Tennessee that are not in the Chesapeake Bay 

watershed.

See the Benefits and Cost Analysis for the Effluent Limitations Guidelines and Standards 

for the Steam Electric Power Generation Point Source Category (Benefits and Cost Analysis), 

(EPA-821-R-15-005) for the data sources used for the threatened and endangered species 

habitats.

2.0 PROXIMITY ANALYSIS FOR IMPAIRED WATERS

A surface water is classified as a 303(d) impaired water when pollutant concentrations 

exceed water quality standards and the surface water can no longer meet its designated uses (e.g., 

drinking, recreation, and aquatic habitat). ERG created an MS AccessTM database that included 

impaired water “flags” that denoted whether the immediate receiving water was located within 

500 feet (buffer zone) of an impaired water. ERG reviewed the following 303(d) impairment 

categories:

 Arsenic.

 Boron.

 Cadmium.

 Chlorides.

 Chromium.

 Copper.

 Lead.

 Manganese.

 Mercury.

 Metals (not Mercury).

 Nutrients.

 Phosphorous.

 Selenium.

 Total dissolved solids. 

 Zinc.

3.0 PROXIMITY ANALYSIS FOR FISH CONSUMPTION ADVISORIES

States, territories, and authorized tribes issue fish consumption advisories when pollutant 

concentrations in fish tissue are considered unsafe for consumption [U.S. EPA, 2011]. ERG 

created an MS AccessTM database that included fish consumption advisory “flags” that denoted 

whether the immediate receiving water was located within 500 feet (buffer zone) of a fish 

consumption advisory water. ERG reviewed fish consumption advisories for arsenic, cadmium, 

lead, mercury, and selenium. 

Table 3 lists the resources that ERG created to document the identification of steam 

electric power plants that discharge to immediate receiving waters that are sensitive 

environments (fish consumption advisory waters).

IRW – immediate receiving water.

a – Record items containing CBI have been removed from the public record.

b – ERG identified 93 immediate receiving waters located within 500 feet of a fish consumption advisory for 

mercury. ERG identified only one location within 500 feet of a fish consumption advisory for another pollutant, 

lead; this location also had an advisory for mercury. To determine if the mercury pollutant removals under the final 

rule would indicate a decrease in potential fish advisories at those locations, ERG compared the calculated fish 

tissue concentrations from the IRW model: wildlife module [see the ERG memorandum, “Wildlife and Human 

Health Modules Supporting Documentation” (DCN SE04452)] to fish advisory screening concentration for 

recreational fishers, 0.40 parts per million [U.S. EPA, 2000]. 

The results of the proximity analysis for fish consumption advisory waters are included in 

Section 3.4.4, Section 7.4.3, and Appendix I of the EA Report. Table A-2, in Attachment A of 

this memorandum, lists the steam electric power plants and immediate receiving waters located 

within 500 feet of a fish consumption advisory water. Table A-8 presents the COMIDs located 

within 500 feet of a fish consumption advisory by pollutant of concern for the evaluated 

wastestreams under the two baseline scopes.

4.0 PROXIMITY ANALYSIS FOR DRINKING WATER RESOURCES

The proximity analysis included the following drinking water resources:

 Drinking water intakes – drinking water sources that collect surface water through a 

public water system. Intakes are protected under the Safe Drinking Water Act (SDWA)

of 1974 and its 1986 and 1996 amendments, which require delegated states and tribes to 

perform routine testing to ensure that they meet state drinking water standards. 

 Public wells – drinking water sources that collect ground water through a public water 

system. Public wells are protected under the SDWA, which requires delegated states and 

tribes to perform routine testing to ensure that they meet state drinking water standards. 

 Sole-source aquifers – drinking water sources that supply at least 50 percent of the 

drinking water consumed in the area overlying the aquifer. These areas can have no 

reasonably available alternative drinking water source(s) if the aquifer were to become 

contaminated.

Note: An “X” indicates that the immediate discharge zone (i.e., COMID) has a fish consumption advisory for the 

pollutant.

a – The outfall coordinates and the receiving water name were claimed CBI in the Steam Electric Survey. However, 

EPA waived the claim because the plant’s outfall coordinates and receiving water were identified in a publically 

available source [AES Eastern Energy LP, 2010].

b – Two steam electric power plants discharge to this COMID. In the modeling analyses, the loadings from the two 

plants are combined and modeled as one receiving water while retaining the name of only one of the two plants. 

c – The outfall coordinates were claimed CBI in the Steam Electric Survey. However, EPA waived the CBI claim 

because the plant’s outfall coordinates were identified in a publically available source [AEC Lowman Steam Plant, 

2004].
