Subject. Speculative Effluent Limits
Archie Elledge and Muddy Creek WWTPs
Forsyth County
This letter is in response to your request for speculative effluent limits for expanded discharges at the City
of Winston Salem's Archie Elledge (NC0037834) and Muddy Creek (NC0050342) Wastewater Treatment Plants.
The Division of Water Quality (Division) has prepared a response to your request for speculative limits at 35 MGD
for Archie Elledge WWTP and 26 MGD at the Muddy Creek WWTP.
The speculative limits were developed based on our understanding of the proposal, in addition to our
understanding of present environmental conditions at the proposed discharge location. The Division can not
guarantee that an NPDES permit will be issued at the proposed location. Final decisions can only be made after the
Division receives and evaluates a formal permit application for the City's proposed discharge. Moreover, the
attached limits are based on an uncalibrated QUAL2E model of the Yadkin River. The City may wish to pursue its
own modeling efforts prior to submitting an expansion request.
In accordance with the North Carolina General Statues, the practicable waste treatment and disposal
alternative with the least adverse impact on the environment is required to be implemented. Therefore, prior to
submittal of an NPDES application, a detailed alternatives analysis must be prepared to assure that the
environmentally sound alternative was selected from the reasonable cost effective options. Attached is a guidance
document that will assist you or your consultant in preparing an engineering alternatives analysis. In addition, due
to the facility's status as Publicly Owned Treatment Works, any upgrades would have to undergo the State
Environmental Policy Act (SEPA) process. You are encouraged to contact the Division's SEPA contact, J. Todd
Kennedy at [phone] ext. 555 prior to beginning plans for expansion.
Based on the available information, tentative limits for the proposed discharge to Salem Creek and the
Yadkin River at 35 MGD for the Archie Elledge WWTP and 26 MGD for the Muddy Creek WWTP are attached.
The limits are based on streamflows calculated based upon regional equations listed in the USGS document Low
Flow Characteristics of Streams in North Carolina. The following flow calculations were made:
Salem Creek
Yadkin River
Average Flow
65 cfs
1849 cfs
Summer 7Qio
15 cfs
554 cfs
Winter 7Qio
18 cfs
854 cfs

An Equal Opportunity Affirmative Action Employer 50% recycled / 10% post -consumer paper

This information was used in conjunction with the proposed effluent characteristics to develop tentative
limits. Please be advised that the limits and monitoring frequencies below were based on the information presented
in the speculative limits request. A complete evaluation of these limits and monitoring frequencies in addition to
monitoring requirements for metals and other toxicants will be addressed upon receipt of a formal NPDES permit
application.
A water quality model of the proposed discharge indicated that it would not cause a violation of the
instream dissolved oxygen standard of 5 mg/L given the effluent limits below. The phosphorus limit represents
the average monthly discharge from each facility calculated between August 1999 and December 2001. Please note
that the following are monthly average limits for the effluent characteristics listed:
Archie Elledge

The Division continues to see elevated chlorophyll -a levels in High Rock Lake and has concerns about the
phosphorus leading to the lake. Be advised that additional reductions in the phosphorus loading from upstream
point sources may be necessary in order to protect the designated uses of High Rock Lake. The Division would be
supportive of any effort by either the City of Winston-Salem or a stakeholder group to develop a nutrient response
model.
Should you have any questions or if you need any additional information, please feel free to contact Natalie
Sierra at [phone], extension 551.

Dear Mr. Goodrich: Sa. le rn
The NPDES permits for Winston-Salem's Archie Elledge (NC0037834) and Muddy
Creek (NC050342) wastewater � treatment plants expire on June 30, 2004.
a
oo t az / 01,41>KAN 12ty -;t1J 1 ( c
To assist us in long-range planning for capital improvements, we need to know if our
wastewater treatment plants are likely to receive more stringent permit limits in the next
permit. Of particular concern is whether or not DWQ plans to implement limits for total
phosphorus and nitrogen.
We would appreciate it if your staff could provide us some probable permit limits for
each of our plants assuming no increase in permitted flow and assuming the permitted
flow limit is raised to 35 MGD at the Elledge Plant and to 26 MGD at the Muddy Creek
Plant.
Please send this information to my attention at City of Winston-Salem; Manson -Meads
Complex; 2799 Griffith Road; Winston-Salem, North Carolina 27103. Thank you for
your assistance and please feel free to call me at [phone] if you have any
questions.

Okay --I quickly reviewed the info. and it looks like the HRL management
strategies have focused on TP and not worried about TN. Jim's report
outlines a nutrient management strategy for the major dischargers less
than 40 miles from High Rock Lake --which includes both Archie and
Muddy. The report states that loads from these dischargers should be
held at the current summer load level.
I have a chart that shows the TP concentrations of both facilities
(summer average from 94-96). I can make a copy of that and bring that
up to you.
I will do some more reading and let you know what I find. Although
chlorophyll a levels in the mainstem are not as much of a concern as the
arms, the nutrient input from the mainstem to the arms is a concern
(Jim's model has shown this). I think this is probably enough
information to hold them to current summer loads (not sure yet what to
do about winter).
I will get back to you with more info. once i delve into again a little
deeper.

hey natalie,
thanks for the email. it looks good except for the CBOD5 limits --those values are
CBODu and not CBOD5 or BOD5. using the same ratios that Jim Blose used, the BOD5
limit for Archie should be 17.857 BOD5 or 14.88 CBOD5 (Using the BOD5:CBOD5 of 1.2
that was used in the renewal of Muddy Creek). This assumes that Archie has the
same BOD5:CBOD5 ratio as Muddy Creek. Have they asked to be permitted in CBOD5
instead of BOD5?
Muddy Creek has the same limit as before.
Let me know if this is unclear, and maybe one of you all should check my math on
those ratios --Let me know if you want to take a look I can run up.

Hey natalie.
how's it going?
I have attached a spreadsheet with the Archie and Muddy Creek
Expansions. Since we last emailed, I ran the model again with the
expanded Archie (with new BOD limit) and then expanded Muddy to 26MGD.
With the current QUAL2E, it looks like with the expanded Muddy plant
(26MGD, with current limits) the DO drops to 5.83 mg/L (segment 17) and
5.76 mg/L at the end of the model (although the DO predictions are
declining at the end of the model --but High Rock Lake is just downstream
of the modeled section --so I don't think it makes sense to extend model
any further--QUAL2E isn't appropriate for the lake).
Anyways, it doesn't look like the expansion of Muddy is going to be a
problem with relevance to DO (nutrients another issue). The model shows
that Archie expansion is more of a concern.
let me know if you have any questions with the spreadsheet. I am also
comptemplating running an uncertainty analysis on the limits for Archie,
to see how sensitive the DO is to small variances in their limits. Let
me know what you think about that.
I still have concerns about the age of the model, but Michelle has said
that it is not uncommon to use this old of a QUAL2E for spec. limits. I
still think we should use pretty soft language, and should possibly
consider trying to get Diane's group over at ESB to conduct a low flow
study and run some long-term BODs on the effluents and tribs.
peace--

1. Assume that Archi Elledge has increased to 35MGD with the limits that are sited on that spreadsheet.
2. Expand Muddy to 26 MGD and see what limits would be required to meet wq standards.

Here's a quick summary of where I am. I have worked with the input files from
Jim Blose's files from 1996 and changed the input file for the Archie Elledge
WWTP (holding Muddy Creek constant). Although the model is uncalibrated, the
time of travel data does not include low flow and the trib. data may not be
realistic (this is all according to Jim's notes (5-15-1996), the input data is
probably the best we have (without redoing time of travel study).
The first question that I tackled was what if Archie expanded to 35mgd and kept
its NH3 limit of 1.2, what would their BOD5 limit be and still be able to
protect the 5 mg/L standard. I held the Muddy Creek plant to its current
limits. I found that if Archie expanded to 35mgd, nh3 at 1.2, do at 6.5, the
stream could handle a CBODu of 50. Using the same BOD5:CBODu ratio that Jim
used (2.8), this comes to a BOD5 of 17.85714.
With these inputs, the DO drops to 5mg/L at segment 2, element 6 (which appears
to be the segment of Muddy Creek between Salem Creek and S. Fork Muddy Creek).
Now I don't know if it is good policy to allow the stream to drop to 5.0 with an
uncalibrated model, but I don't know what our general thought on that is.
I have attached a spreadsheet which shows the input and output files of my
various runs. I hope it is self explanatory.
Tomorrow I will tackle the second question about the expansion of the Muddy
Creek plant. If you have any questions, please let me know.
I hope this is helpful.

hey natalie, thanks for the email. Sorry about Susan's email --I forgot. I will
pull the ambient data and the data for the discharger coalition stations that are
on the modeled reach of the streams and the Yadkin. I will also talk with Adugna
about his thoughts on age of a QUAL2E model and when should it be updated. I have
only worked on one rather large QUAL2E and that is a new one --so I'm not really
sure what our policy or practice has been on that. I will also check into the
npdes dischargers on the tribs to see if their outputs have changed since 1990. I
may need your help with that one.
Cool?

hey Natalie, I've gone through Jim's notes and here is what I found --
It looks like Salem and Muddy Creek were modeled 1989-1991, including
calibration runs for both summer and winter. The model was extended to
Yadkin College on the Yadkin River in 1989 as well. This portion of the
model was not calibrated. The model was extended down the Yadkin to
Grants Creek in 1995, this portion was also not calibrated.
One of my concerns is that the NPDES effluents on the tribs to Salem,
Muddy and the Yadkin may have changed in flow and BOD, NH3 and NO2/3
load since the model was originally developed in 1989. I am also
concerned that being a fairly urban stream, changes in development
patterns since 1989 could have changed the BOD load from the tribs. The
CBODu concentration for all of the tribs (except Grants Creek) at low
flow is 3.30 mg/L. This may or may not be valid today. In order for
BOD levels to be updated, a low flow study would have to be completed,
samples pulled and a long-term BOD test (often 90-120 days) run on
samples for each of the tribs--a fairly time intensive study.
There is an ambient site on Muddy Creek below the confluence with Salem
Creek. I can check into the DO at that station.
Another question I have is why Jim reran the model in 1996. It looks as
if the permits were renewed in 1994. Was there a spec. limit request in
1996 which spurred Jim's modeling? (I think we talked about this
earlier). From his notes it looks like Muddy Creek WWTP asked about
expanding to 40MGD.
I'm not sure who makes the calls on updating the QUAL2E, and maybe that
is something that we could convice Winston-Salem to do and/or pay for.
Let me know your thoughts.
Thanks.
