MEMORANDUM 

TO: Bill Swietlik, EPA 

FROM: Ryan Novak, Adam Humphreys, and Patrick Goodwin, ERG 

DATE: September 30, 2015 

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

SE04538) 

 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 used in the 

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.2 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. 

Table 1. Receiving Water Characteristic Input Variables in Water Quality Model 

Input Type Input Variable Input Description 

Site-specific Qriver Water body annual flow 

Site-specific v Receiving water velocity 

Site-specific Len Length of stream reach 

Site-specific Qlake Average discharge flow exiting the lake/pond system 

Site-specific Area Surface area of the lake, pond, or reservoir 

Site-specific dz,lake Depth of the lake, pond, or reservoir 

Site-specific Qcool Total cooling water effluent flow by receiving water 

 

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.

 For further details on the equations and assumptions used in the steady state equilibrium-partitioning model of the 

immediate receiving waters, see Appendix C in EPA’s 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).

1. SITE-SPECIFIC RECEIVING WATER INPUT VALUES

 In the immediate receiving water quality model there are three main categories of sitespecific variables: receiving water characteristics for rivers and streams; receiving water 

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

final rulemaking, ERG’s approach for identifying the input values required for the different 

water body types and cooling water discharges was consistent with the methodology for the 

proposed rule, which is described in the “Water Quality Model: Plant and Receiving Water 

Characteristics” memorandum (DCN SE01955). As described in the “Water Quality Model: 

Plant and Receiving Water Characteristics” memorandum, ERG used latitude and longitude 

information reported by plants in the Questionnaire for the Steam Electric Power Generating 

Effluent Guidelines (Steam Electric Survey) (DCN SE01958) to index plant outfalls that 

discharge the evaluated wastestreams to the National Hydrography Dataset Plus (NHDPlus) 

geographical information system (GIS) dataset.3

 ERG used plant-reported names of surface 

waters in conjunction with outfall coordinate information to assign pollutant loadings associated 

with the discharge of the evaluated wastestreams from these outfalls to the most appropriate 

COMID. The COMID is the common identifier number for a NHD stream segment and is the 

smallest stream segment defined within NHD Plus. 

1.1 Selection of COMIDs for Receiving Waters Included in the EA

 For the final rulemaking, ERG did not reevaluate the selection of COMIDs for receiving 

waters included in the EA because no new plants were added to the scope of the analysis of the 

proposed rule. The COMID selection process for the proposed rule is described in the “Water 

Quality Model: Plant and Receiving Water Characteristics” memorandum (DCN SE01955). 

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

 ERG identified 222 unique COMIDs or receiving waters associated with the 195 plants 

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

discharges from multiple plants. 

 For the final rulemaking, ERG did not analyze future profile scenarios. As a result, ERG 

did not include the future profile plants identified for the proposed rule. Attachment 2 presents 

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

receiving waters evaluated in the EA for the final rulemaking. 

 

3

 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.

1.2 River and Stream Characteristics

 ERG identified 183 unique rivers and streams that receive discharges of the evaluated 

waste streams for inclusion in the water quality model (Attachment 2). For the final rulemaking, 

ERG followed the same process to extract river and stream characteristics as described in the 

“Water Quality Model: Plant and Receiving Water Characteristics” memorandum (DCN 

SE01955). Attachment 3 presents the stream length, average annual receiving water flow, and 

velocity input values for each river included in the water quality model. 

1.3 Lake, Pond and Reservoir Characteristics

 ERG identified 26 lakes that receive direct discharges of the evaluated waste streams for 

inclusion in the water quality model. For the final rulemaking, ERG followed the same process 

to extract lake characteristics as described in the “Water Quality Model: Plant and Receiving 

Water Characteristics” memorandum (DCN SE01955). Attachment 4 lists the sources of 

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

model. 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

 For the final rulemaking, ERG considered the same cooling water scenarios and followed 

the same process to make adjustments as described in the “Water Quality Model: Plant and 

Receiving Water Characteristics” memorandum (DCN SE01955). 

2. REGIONAL ASSUMPTION INPUT VALUES

 For the final rulemaking, ERG used the same regional data to populate input values for 

wind velocity, air temperature, water body temperature, and total suspended solids, as described 

in the “Water Quality Model: Plant and Receiving Water Characteristics” memorandum (DCN 

SE01955).

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 (DCN SE04446). 

c – This field indicates if the plant-receiving water is modeled in the EA scope accounting for the Clean Power Plant 

(CCP). 

d – 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.
