FROM: Kristi Bubb, Lydia Lambert, and Patrick Goodwin, ERG 

DATE: April 19, 2013 

SUBJECT: Water Quality Model: Plant and Receiving Water Characteristics (DCN 

SE03573) 

 This memorandum documents the methodology used in the environmental assessment 

(EA) for selecting the receiving water characteristic input data for the equilibrium partition 

coefficient water quality model of the immediate receiving waters from steam electric 

discharges.1

 The receiving water characteristic data are broken into two primary types: sitespecific input values based on data available for a given plant or receiving water, and assumption 

values based on data aggregated from the region of the receiving water (if site-specific data are 

not available). Table 1 presents the immediate receiving water characteristic input variables for 

the water quality model.

characteristics for lakes, ponds, and reservoirs; and cooling water discharge assumptions. This 

section describes the methodology used to identify the input values required for the different 

water body types and for the cooling water discharges. 

 

1.1 Selection of COMIDs for Receiving Waters Included in the EA

 The National Hydrography Dataset (NHD) Plus geographical information system (GIS) 

dataset is the primary data source for the receiving water input variables within the water quality 

model. The NHD Plus dataset is a suite of geospatial datasets that integrates the features from the 

NHD, the National Elevation Dataset (NED), and the National Watershed Boundary Dataset 

(WBD) into one GIS dataset (USGS and U.S. EPA, 2010). NHD Plus includes medium 

resolution NHD (1:100,000 scale) stream network information, stream characteristic attribute 

data (e.g., stream flow, velocity, slope), and elevation-derived catchment information (USGS and 

U.S. EPA, 2010). ERG downloaded the most recent version of the NHD Plus hydrologic region 

files available at http://www.horizon-systems.com/NHDPlus/index.php on August 18, 2010. 

Attachment 1 lists all of the NHD Plus hydrologic region files used in the EA. 

 ERG used latitude and longitude information reported in the Questionnaire for the Steam 

Electric Power Generating Effluent Guidelines (Steam Electric Survey) (DCN SE01958) to 

index the final outfalls that discharge the evaluated waste streams2 to the NHD Plus dataset. ERG 

used the following multi-step process to verify outfall information reported in the Steam Electric 

Survey and to ensure identification of the appropriate receiving water: 

 Step 1: Verify that plant latitude and longitude values provided in the Steam 

Electric Survey fall within the correct state. ERG identified 281 plants3 that directly 

discharge the evaluated waste streams.4 ERG created a point layer of all 281 plants that 

discharge the evaluated waste streams based on the center point latitude and longitude 

data provided in the Steam Electric Survey (Question A5-1). ERG used the plant center 

point layer to join by location to the ESRI Detailed Boundary of the United States Layer. 

ERG evaluated whether the state identified by the plant center point latitude and 

longitude was consistent with the state provided in the address for the plant in the Steam 

Electric Survey (Question A1-1). Plants whose latitude and longitude did not match the 

state provided in the address were flagged for further QC analysis. 

 Step 2: Verify that the outfall latitude and longitude values provided in the Steam 

Electric Survey fall within five miles of plant center point latitude and longitude. 

ERG created a point layer of all final outfalls discharging the evaluated waste streams 

based on the latitude and longitude data provided in the Steam Electric Survey (Question 

A2-5). ERG created a five-mile buffer around each plant center point that was verified in 

 

2

 The evaluated waste streams are defined as the subset of combustion wastewaters evaluated in the environmental 

assessment and benefits analyses that includes flue gas desulfurization (FGD) wastewater, fly ash transport water, 

bottom ash transport water, and leachate from landfills or surface impoundments containing combustion residuals.

 See Table 2-2 of the EA Report for a summary of the number of plants evaluated in the EA. 4

 See Section 10 of EPA’s Technical Development Document for the Proposed Effluent Limitations Guidelines and 

Standards for the Steam Electric Power Generating Point Source Category (TDD) (DCN SE01964) for a 

description of the methodology used to calculate pollutant loadings directly discharged from steam electric power 

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

Step 1. ERG selected the five-mile buffer based on knowledge gained from site visits and 

best professional judgment on typical distances of outfalls from plants. ERG joined by 

location the final outfall points to the five-mile buffer for each plant center point to verify 

that all final outfalls for each plant were within five miles of the correct plant. Outfalls 

that fell outside of the five-mile buffer for each plant center point were flagged for further 

QC analysis. 

 Step 3: Index final outfalls to NHD Plus. ERG indexed or snapped the final outfall 

points to the closest NHD Plus steam reach within 500 feet of the outfall point. ERG used 

a 500-foot buffer to account for nominal error in the latitude and longitude values 

provided in the Steam Electric Survey for the outfalls. ERG extracted the receiving water 

name from NHD Plus for the selected COMID. The COMID is the common identifier 

number for a NHD stream segment and is the smallest stream segment defined within 

NHD Plus. For each outfall, ERG compared the receiving water name in NHD Plus with 

the receiving water name reported in the Steam Electric Survey (Question A2-8). Outfalls 

where the NHD Plus receiving water name did not match the Steam Electric Survey name 

were flagged for further QC analysis. 

 Step 4: Select the unique COMID within NHD Plus to represent the receiving water 

in the EA. If the receiving water name in NHD Plus matched the receiving water name 

reported in the Steam Electric Survey, ERG assigned the COMID to the plant-receiving 

water5

 combination in the EA. If a plant discharges to multiple outfalls along the same 

receiving water, ERG selected the most downstream COMID to represent the receiving 

water in the EA. 

 Step 5: Manually index and verify remaining final outfalls. ERG manually indexed 

the remaining final outfalls that did not pass the quality checks outlined in Steps 2-4 

using information (e.g., plant address) or maps provided in the Steam Electric Survey or 

other publically available information on the plant (e.g., NPDES permits). If the outfall 

latitude and longitude information was in question, ERG assumed that the receiving 

water name reported in the Steam Electric Survey was correct and indexed the outfall to 

the nearest COMID that matched the receiving water name based on the plant center 

point. Some smaller receiving waters (e.g., unnamed tributaries or ditches) reported in the 

Steam Electric Survey are not represented in NHD Plus. If ERG was unable to identify 

the correct receiving water by name, ERG selected the COMID for the next downstream 

water reported in the Steam Electric Survey (Question A2-8). 

 ERG identified 316 unique COMIDs or receiving waters associated with the 281 plants 

that directly discharge the evaluated waste streams. ERG identified seven COMIDs that received 

discharges from multiple plants. 

 As part of the future profile analysis, ERG identified an additional nine plants that may 

directly discharge the evaluated waste streams under varying future profile scenarios.6

 All EA analyses are conducted at the immediate receiving water level and not at the outfall level. A “plantreceiving water” is the unique identifier used in the EA analyses and consists of the unique combination of a plant 

name and receiving water name as identified in the Steam Electric Survey. 6

Page 4 

the nine plants were included in the Steam Electric Survey. ERG used the same methodology as 

described above for current profile plants to determine the COMIDs for these three future profile 

plants. For the remaining six plants, ERG identified the city and state provided in the U.S. 

Department of Energy 2009 Energy Information Administration (EIA) database for proposed 

plant locations and used best professional judgment to select the largest surface water within the 

city as the probable discharge location for the future plant. ERG identified nine COMIDs 

associated with the nine additional plants included in the future profile. Attachment 2 presents 

the COMID, plant name, receiving water name, and receiving water type for all immediate 

receiving waters evaluated in the current and future profiles for the EA. 

 Only receiving waters with a river or lake designation were modeled in the immediate 

receiving water modeling analysis. The specific hydrodynamics and scale of the analysis 

required to appropriately model and quantify receiving water concentrations in the Great Lakes 

and estuary systems are more appropriately handled separately on a case study basis. ERG 

evaluated the impacts to the Great Lakes and Chesapeake Bay systems from a total mass 

loadings perspective in a separate qualitative analysis, discussed in the Loadings Analysis for the 

Steam Electric ELGs Environmental Assessment Memorandum (DCN SE01956). The following 

subsections present the methodology for selecting the receiving water characteristics for rivers 

and lakes included in the water quality model. 

1.2 River and Stream Characteristics

 ERG identified 270 unique rivers and streams (261 rivers and streams in the current 

profile and 9 in the future profile) that receive discharges of the evaluated waste streams for 

inclusion in the water quality model (Attachment 2). ERG used the identified COMID to extract 

the stream length (Len), average annual receiving water flow (Qriver), and velocity (v) estimates 

for each river or stream included in the immediate receiving water modeling analysis. The 

attribute files associated with NHD Plus flowlines include estimated mean annual flow in cubic 

feet per second (cfs) calculated by the Unit Runoff Method (MAFlowU) and Vogel Method 

(MAFlowV) (USGS and U.S. EPA, 2010). When provided, ERG selected the flow value 

calculated by the Vogel Method (Vogel et. al, 1999) and defaulted to the Unit Runoff flow value 

when the MAFlowV value was null. NHD Plus also provides two estimates of mean annual 

velocity in feet per second (fps) using the Jobson Method (1996) and based on the MAFlowU 

and MAFlowV mean annual flow values. ERG selected the mean annual velocity calculated 

based on the Vogel Method flow (MAVelV) when available and defaulted to the velocity based 

on the Unit Runoff flow (MAVelU) when the MAVelV value was null. ERG used the length of 

the COMID stream segment provided in NHD Plus (LengthKM) in kilometers as input for the 

length input variable in the water quality model. Attachment 3 presents the stream length, 

average annual receiving water flow, and velocity input values for each river included in the 

water quality model for the current and future profiles. 

1.3 Lake, Pond and Reservoir Characteristics

 ERG identified 36 lakes that receive direct discharges of the evaluated waste streams for 

inclusion in the water quality model.7 The three primary lake characteristic input variables in the 

 Future Profile Sensitivity Analysis Memorandum (DCN SE01989). 7

 ERG did not identify any lakes associated with the nine additional plants identified for the future profile. 
Memorandum 

April 19, 2013 

Page 5 

water quality model include: average annual discharge outflow from the lake (Qlake), lake surface 

area (Area) and lake depth (dz,lake). ERG manually identified the outflow flowline in NHD Plus 

for each lake and extracted the mean annual flow calculated by the Vogel Method (Vogel et. al, 

1999) and defaulted to the Unit Runoff flow value when the MAFlowV value was null. Lake 

characteristic data, in particular lake depth, can often be difficult to identify using national 

datasets. ERG estimated the size of the lake surface area based on the area of the lake polygon 

(AreaSqKm) represented in the NHD Plus waterbody layer for the COMIDs in parentheses 

identified in Attachment 2. For the five lakes not represented in the NHD Plus polygon 

waterbody layer, ERG performed internet searches to identify estimates of lake surface areas 

from alternative data sources (e.g., topographical maps, university or federal and state 

government websites, and fishing websites). ERG also performed Google searches to identify 

average depth information provided by university or federal and state government websites. 

When average depth was unavailable, ERG used the maximum depth provided by the identified 

data sources. If the depth information could not be obtained from government or university 

resources, ERG referenced private organizational websites (e.g., recreational fishing or 

environmental interest group websites), contacted state and local government agencies to obtain 

the depth information, or used topographic maps to estimate the depth of the receiving lake. ERG 

could not identify depth information for one lake included in the modeling analysis. ERG 

calculated an average depth among the other receiving lakes and used the average lake depth 

value as a surrogate value for the missing lake depth. Attachment 4 lists the sources of 

information used to identify the lake surface area and depth values used in the water quality 

model. The source documents are provided separately in Attachment 8 (refer to DCN 

SE01955A3). Attachment 5 presents the average annual discharge outflow, surface area, and 

depth input values for each lake included in the water quality model. 

1.4 Cooling Water Contributions

 Cooling water is frequently commingled with the evaluated waste streams prior to 

discharge and can result in a significant amount of dilution of the pollutant loadings in the 

immediate receiving waters. There are three primary scenarios under which cooling water is 

commingled and discharged with the evaluated waste streams: 

Cooling Water Scenario 1 - Cooling water intake and discharge of commingled cooling water 

and the evaluated waste streams occur within the same water body. 
Memorandum 

April 19, 2013 

Page 6 

Cooling Water Scenario 2 - Cooling water intake is located on one water body and the 

commingled cooling water and evaluated waste streams are discharged to a different water body. 

Cooling Water Scenario 3 – Cooling water intake is located on one water body and cooling 

water is discharged back into the original water body either on its own or commingled with the 

evaluated waste streams (green arrow); however, some percentage of the total cooling water 

intake flow is commingled with the evaluated waste streams and discharged to a different water 

body (red arrow).

 ERG considered the various cooling water scenarios and, in some cases, adjusted the 

values for water body annual flow (Qriver) used in the water quality model. These adjustments are 

intended to reflect the flow contributions of the cooling water discharges that otherwise would 

not be captured in the flow rates discussed in Section 1.2. Cooling water flows were included in 

the water quality model only if they were discharged from the same outfall as an evaluated waste 

stream as identified in the Steam Electric Survey (Questions A2-5 and A2-10).8

 As a 

simplification of the cooling water flow methodology, ERG excluded cooling water flows that 

were discharged from a separate outfall to the same receiving water as the evaluated waste 

streams. ERG excluded these cooling water flows due to the uncertainty regarding the relative 

upstream vs. downstream locations of the two outfalls, and the complexity in determining 

whether cooling water may or may not impact receiving water concentrations. ERG also 

excluded cooling water flows commingled with the evaluated waste streams for those plants that 

 

8

 For plants that did not provide a cooling water flow in Survey Questions A2-5 and A2-10, ERG used the cooling 

water flows provided in Question A7-1. 
Memorandum

Page 7 

fall under Cooling Water Scenario 1 as there is no effective increase in surface water flow. ERG 

included cooling water flows commingled with the evaluated waste streams for plants that fall 

under Scenarios 2 and 3. Some plants under Cooling Water Scenario 3 discharge to multiple 

receiving waters where one of the receiving waters may coincide with the cooling water intake 

source water. For these plants, ERG excluded the cooling water flows commingled with the 

evaluated waste stream that are discharged to the cooling water intake source water (green arrow 

in Cooling Water Scenario 3 figure) and included the commingled cooling water flows for the 

remaining receiving waters associated with the evaluated waste streams (red arrow in Cooling 

Water Scenario 3 figure). 

 Based on the responses to the Steam Electric Survey, ERG identified 106 plants with 

cooling water commingled with the evaluated waste streams prior to discharge. ERG used 

information provided in the January 2000 Industry Short Technical Questionnaire: Phase II 

Cooling Water Intake Structures (316b Survey) (Question 11(f)) to identify the name of the 

source water body for the cooling water intake structure for each plant. ERG compared the 

source water body name in the 316b Survey to the immediate receiving water names identified in 

Attachment 2 for each plant. If the cooling water source water body name matched the 

immediate receiving water name, ERG classified the plant as a Scenario 1 plant. If none of the 

water body names match, ERG classified the plant as a Scenario 2 plant. If the plant discharges 

the evaluated waste streams to multiple receiving waters, ERG determined if any of the receiving 

water names matched the cooling water source water body name. If one of the multiple receiving 

waters matched the cooling water source water body name, ERG classified the plant as a 

Scenario 3 plant and only excluded cooling water flows to the matching source water body. ERG 

identified 31 plants that discharge commingled cooling/waste streams and for which the source 

water body name information was not available in the 316b Survey dataset. For each plant with 

an unknown cooling water source, ERG used best professional judgment in assessing the 

probability that the receiving water body for the evaluated waste streams could be used as a 

cooling water intake source based on surface water flow and size of the water body. 

 Table 2 presents the number of plants that fall within each of the cooling water scenario 

categories. ERG identified 39 plants (40 COMIDs or receiving waters) that discharge cooling 

water commingled with the evaluated waste streams to a different water body than the source 

water body for the cooling water intake. The majority of the Cooling Water Scenario 3 plants 

discharge cooling water commingled with the evaluated waste streams to the same water body as 

the cooling water source water body. Based on receiving water flows and best professional 

judgment, ERG included cooling water flows for 16 plants (16 COMIDs or receiving waters) of 

the 31 plants with an unknown source water body for the cooling water intake. Attachment 6 

presents the cooling water flows used in the water quality model.

2. REGIONAL ASSUMPTION INPUT VALUES

 ERG used regional data to populate input values for the following four model input 

variables: wind velocity (W10), air temperature (Ta), water body temperature (Tw), and total 

suspended solids (TSS). ERG downloaded the National Climatic Data Center (NCDC) national 

mean annual wind speed and air temperature GIS shapefiles (http://hurricane.ncdc.noaa.gov/cgibin/climaps/climaps.pl?directive=quick_results&subrnum=&pop=YES) available on May 12, 

2011 (Figures 1 and 2). ERG created a point file snapped to the center point of the COMID lines 

identified in Attachment 2. ERG overlaid the COMID point file with the NCDC GIS shapefiles 

and extracted the wind speed and air temperature ranges associated with each immediate 

receiving water. As an environmentally conservative estimate, ERG selected the lower range 

value for wind speed and air temperature as input values for the water model (e.g., if the NCDC 

dataset represented the mean wind speed for a given location as 8.0-8.9 mph, ERG selected the 

value of 8.0 mph for use in the model).

 ERG downloaded the June 2005 version of 1:2,000,000-Scale Hydrologic Unit 

Boundaries GIS layer available at http://water.usgs.gov/GIS/huc.html on August 24, 2010. ERG 

used the COMID point file to extract the hydrologic unit code (HUC) for each receiving water 

and determined the hydrologic region. ERG used the identified hydrologic region for each 

receiving water to select the appropriate water body temperature and TSS input values based on 

data presented in the April 2010 Human and Ecological Risk Assessment of Coal Combustion 

Wastes (CCW) report. Table 3 presents the TSS concentrations compiled from Legacy STORET 

data. ERG selected the geometric mean value as the water quality input value for each receiving 

water. Table 4 presents the average water body temperatures compiled from Legacy STORET 

data. Attachment 7 presents the wind velocity, air temperature, water body temperature, and TSS 

input assumptions for each receiving water included in the water quality model.

Source: U.S. EPA, 2012c and U.S. EPA, 2012d. 

a – COMIDs presented for lakes represent the stream reach flowing out of the lake. 

b – ERG classified the receiving waters into one of four categories: river, lake, Great Lake, and estuary. Only 

receiving waters with a river or lake designation were modeled in the immediate receiving water modeling analysis. 

The specific hydrodynamics and scale of the analysis required to appropriately model and quantify receiving water 

concentrations in the Great Lakes and estuary systems are more appropriately handled separately on a case study 

basis. ERG evaluated the impacts to the Great Lakes and Chesapeake Bay systems from a total mass loadings 

perspective in a separate qualitative analysis, discussed in the Loadings Analysis for the Steam Electric ELGs 

Environmental Assessment Memorandum (DCN SE01956). 

c – Multiple plants discharge to this COMID. In the modeling analyses the loads from the two plants are combined 

and modeled as one plant-receiving water. 

d – The specific receiving water reported in Steam Electric Survey could not be identified in NHD Plus for this 

plant. ERG selected this COMID as a surrogate receiving water to extract the receiving water characteristic data. In 

the EA these plant-receiving waters were modeled as two distinct receiving waters. 

e – This COMID was only included in the future profile analysis discussed the Flue Gas Desulfurization Future 

Profile Sensitivity Analysis Memorandum (DCN SE01989). 

f – The outfall coordinates and the receiving water name were claimed confidential business information (CBI) in 

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]. 

g – 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].
