# MEMORANDUM

TO: Bill Swietlik, EPA

FROM: Lydia Lambert, ERG

DATE: April 19, 2013

SUBJECT: Proximity Analyses Methodology (DCN SE03575)

ERG prepared an environmental assessment (E A) for the proposed effluent limitations

guidelines and standards (ELGs) for the steam el ectric power generating poi nt source category.

This memorandum documents the methodology and re sources used in the EA for identifying

surface waters that receive discha rges of the evaluated waste st reams and are located in close

proximity to the following sensitive environments:

 Impaired waters;

 Fish consumption advisories;

 Drinking water intakes;

 Public wells; and

 Sole-source aquifers (SSAs).

1.0 R ESOURCES



# ERG identified a total of 281 plants 1 

# that directly discharge the evaluated waste streams

under the current profile. 2 

# A subset of the 281 plants discharges to multiple receiving waters;

therefore, ERG evaluated the immediate discharge point 3 

# in 317 unique plant-receiving water

combinations. ERG first identified the immedi ate receiving water according to the methodology

documented in the Water Quality Model: Plant and Receiving Water Characteristics

Memorandum (DCN SE01955). For the purposes of this analysis, ERG then selected an

immediate discharge point on the receiving water w ith the assumption that each plant is directly

discharging all evaluated waste streams to th e same point on the immediate receiving water.

ERG conducted the proximity analyses usi ng Esri ArcGIS Desktop software and NHD

Plus-indexed geographical information system (GIS ) datasets that docume nt the location of the

sensitive environments. In GIS, a geographic feat ure is represented as a point, line, or polygon

file. ERG created a point file to represent the immediate discharge point approximately halfway

plants. See Table 6-1 of the EA Report for a summary of the evaluated waste streams under each regulatory option.

downstream on the receiving water segment. ERG then created a user-defined buffer zone

around each point to identify the plants whose im mediate discharge points are located in close

proximity to sensitive environments. An example of a plant directly di scharging the evaluated

waste streams to an impaired river and lake in GIS is shown Figure 1 below. The user-defined

buffer zones and GIS datasets used in each proxim ity analysis are presented in Table 1 below.

2.0 M ETHODOLOGY



# This section presents the methodology used to identify plants located in close proximity

to impaired waters, waters issued fish consum ption advisories, drinking water intakes, public

wells, and SSAs.

2.1 Impaired Waters

ERG identified plants that are directly discharging the evaluated waste streams to

impaired waters by creating a 500-foot buffer around the immediate di scharge points. ERG

selected the 500-foot buffer to account for nomin al projection errors between the NHD Plus GIS

datasets. ERG then performed a spatial join be tween the buffer and the line and polygon files

(i.e., rivers and lakes) from the 303(d) List ed Impaired Waters NHD Indexed Dataset and

selected the immediate discharg e points whose buffers intersecte d the line and polygon files.

Attachment 1 lists all of the plan ts that, based on this analysis, directly di scharge to impaired

waters.

ERG identified the cause of the impairment in the rivers and lakes that intersected the

buffer by linking the “source feature ID” field in the 303(d) Listed Impaired Waters NHD

Indexed Dataset with the “listed water ID” field in the ATTAINS Dataset. Attachment 2 lists the

plants’ immediate receiving waters that ar e impaired for pollutants commonly found in

combustion wastewater discharges from steam electric power plants (i.e., pollutants of concern).

For more information on the results of the impaired waters proximity analysis, refer to

Section 3.4.1 (Proximity to Impa ired Waters) and Section 6.4.1 (Impaired Waters) of the EA

Report.

2.2 Fish Consumption Advisories

The methodology for the fish consumption advi sories analysis is very similar to the

impaired waters analysis. For th e fish consumption advisories an alysis, ERG performed a spatial

join between the 500-foot buffer around the imme diate discharge points to the line and polygon

files from the Fish Consumption Advisories NHD Indexed Dataset and se lected the immediate

discharge points whose buffers inte rsected the line and polygon files. Attachment 3 lists all of the

plants that, based on this analys is, directly discharge to waters issued a fish consumption

advisory.

ERG identified the cause of the advisory in th e rivers and lakes that intersected the buffer

by linking the “source feature c ode” field in the Fish Consum ption Advisories NHD Indexed

Dataset to the “ADVNUM” field in the NLFWA Dataset. Attachment 4 lists the plants’

immediate receiving waters issued an advisory for a pollutant of concern.

For more information on the results of the fi sh consumption advisory analysis, refer to

Section 3.4.2 (Proximity to Fish Consump tion Advisory Waters) and Section 6.4.2 (Fish

Advisory Waters) of the EA Report.

2.3 Drinking Water Resources

ERG identified plants that are directly disc harging the evaluated waste streams in close

proximity to drinking water inta kes, public wells, and SSAs by creating a five-mile buffer around

the immediate discharge points. ERG used best professional judgment in assigning a distance of

five miles for the buffer. 4 

# ERG then performed a spatial join between the buffer and the point

and polygon files from the following datasets and selected the points that fell completely inside

the buffer and polygons that intersected the buffer:

 Drinking Water NHD Indexed Dataset: This is a national dataset of public water

system source facilities. ERG created a point file that contains only the latitude and

longitude coordinates of drinki ng water intakes and public wells. 5



#  Sole Source Aquifers NHD Indexed Dataset: This is a national dataset of SSAs.

Attachment 5 lists all of th e plants that, based on this analysis, are located in close

proximity to drinking water inta kes, public wells, and SSAs.

For more information on the results of the drinking water proximity analysis, refer to

Section 3.4.4 (Proximity to Drinking Water Resources) of the EA Report.

4 

# When applying the five-mile buffer to identify potentially affected drinking water resources, ERG did not evaluate

whether the identified resources are located upstream or do wnstream of the immediate discharge point. ERG would

need to perform further analysis to identify those speci fic resources that are located downstream of immediate

discharge points.

5 

# The drinking water facilities excluded from this analysis include cistern, clear well, common headers, consecutive

connection, distribution system zone, infiltration gallery, no n-piped, other, pressure control, pump facility, roof

catchment, sampling station, storage, surface impoundment, transmission main, and treatment plant.
