# 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 Protec tion Agency (EPA) in the development of

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

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

assessment (EA) analyses to evaluate envir onmental 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 wa ter characteristic input data for the equilibrium partition

coefficient water quality model of the immedi ate 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 (i f site-specific data are

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

the water quality model.

Input Type Input Variable Input Description

Site-specific Q rive r 

# Water body annual flow

Site-specific v Receiving water velocity

Site-specific Len Length of stream reach

Site-specific Q lake 

# Average discharge flow exiting the lake/pond system

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

Site-specific d z,lake 

# Depth of the lake, pond, or reservoir

Site-specific Q cool 

# 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 (s ee 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).

# In the immediate receiving water quality m odel there are three main categories of sitespecific variables: receiving water characterist ics 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 i nput values required for the different

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

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

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

Plant and Receiving Water Characteristics” me morandum, ERG used latitude and longitude

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

Effluent Guidelines (Steam Electric Survey) (DCN SE0195 8) to index plant outfalls that

discharge the evaluated wastes treams 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 evalua ted 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 reevalua te 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 Ch aracteristics” memo randum (DCN SE01955).

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

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

that directly discharge the eval uated 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 identifie d 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 de sulfurization (FGD) wastewater , fly ash transport water,

bottom ash transport water, and leach ate from landfills or su rface impoundments containi ng 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 a nd stream characteristics as described in the

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

SE01955). Attachment 3 presents the stream le ngth, 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 di scharges 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 SE 01955). Attachment 4 lists the sources of

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

model. Attachment 5 presents the average annu al discharge outflow, surface area, and depth

input values for each lake includ ed 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 desc ribed in the “Water Quality Model: Plant and

Receiving Water Characteristic s” memorandum (DCN SE01955).

in the “Water Quality Model: Plant and Recei ving Water Characteris tics” memorandum (DCN

SE01955).

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

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

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

The specific hydrodynamics and scale of the analysis requi red 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 th e 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 mode ling analyses the loads from the two plants are combined

and modeled as one plant-receiving water.Attachment 3September 30, 2015Page 3-1Attachment 3: Receiving Water Characteristic Input Values for Rivers in the Water Quality ModelCOMIDPlant NameReceiving Water NameAverage AnnualDischarge Flow(Qriver)(cfs)bAverageAnnualVelocity (v)(fps)bStreamLength(Len)(km)b11050038 Cheswick Power Station Allegheny River 18,300 1.98 2.394742231 RRI Energy Keystone Generating Station Allegheny River 15,200 1.9 1.25381688 Muskogee Generating Station Arkansas River 26,600 2.64 0.4655555198 Twin Oaks Power Bee Branch 2.92 0.832 10.918819844 Sheldon Station Big Blue River 613 1.6 5.5923850957 TransAlta Centralia Generation, LLC Big Hanaford Creek 57.7 0.933 5.2118104316 R.D.
