Subject: Issuance of NPDES Permit NC0050342
Muddy Creek WWTP
Forsyth County
Dear Mr. Saunders,
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
This final permit includes following major changes from the draft permit sent to you on May 20, 2009:
• The limit for Hg was changed to daily maximum and monitoring was changed to 2/Month to be consistent
with the Archie Elledge permit. If monitoring results in the future indicate that the Hg limit is not needed,
the facility can apply for a permit modification.
The Division has reviewed your request regarding the change in the procedure for Chronic Toxicity testing.
The Division is unable to grant this request. The existing test procedure has been developed to provide information
regarding the toxic effluent concentration, which is necessary to determine the cause of toxicity and provide
protection of water quality in the receiving stream. This procedure is applied uniformly for all facilities and cannot
be changed.

If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt
of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh,
North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
Please note that this discharge ultimately flows to High Rock lake, which is listed as impaired on the 303(d)
list for chlorophyll -a due to excessive nutrient inputs. A TMDL is currently in progress, and nutrient limitations are
a potential future requirement.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements
to obtain other permits which may be required by the Division of Water Quality or permits required by the
Division of Land Resources, the Coastal Area Management Act or any other Federal or Local governmental permit
that may be required. If you have any questions concerning this permit, please contact Sergei Chernikov at
telephone number [phone].

A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 5.5 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998)
or subsequent versions. The tests will be performed during the months of January, April, July, and October.
Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all
treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit
limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months
as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February
1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that
does have a detectable impairment of reproduction or survival. The definition of "detectable impairment,"
collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase
II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for
the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to
the following address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Branch at
the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month. Should any test data from this monitoring requirement or tests performed
by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit
may be. re -opened and modified to include alternate monitoring requirements or limits.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to
include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.

Permit NC0050342
NOTE: Failure to achieve test conditions, as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following
the month of the initial monitoring.
A. (4) Potential INSTREAM sampling exemption
Per 15A NCAC 2B .0505(c)(4), stream sampling (as well as influent/effluent sampling) may be discontinued when
flow conditions could result in injury or death of the person(s) collecting the samples.
In such cases, on each day that sampling is discontinued, written justification shall be specified in the monitoring
report for the month in which the event occurred. This provision shall be strictly construed and may not be utilized
to avoid the requirements of this Section when performance of these requirements is attainable.
When there is discontinuance pursuant to this provision, stream sampling shall be resumed at the first opportunity
after the risk period has ceased.

SUMMARY
This facility is a major municipal treatment plant operating in Forsyth County. Over the
years it has undergone numerous expansions. The facility is currently permitted to
discharge 21.0 MGD
The facility operates two outfalls. The primary outfall is labeled 001. The second outfall,
002, is essentially an overflow outfall for 001. This outfall is used when discharge to the
Yadkin River through 001 is not possible. Discharge through 002 occurs perhaps once a
year for approximately 2 hours during severe flooding events.
The facility serves 121,151 people in Winston-Salem, Clemmons, and a few other small
communities. The City administers an industrial pretreatment program to control the
discharge of industrial and commercial wastes into its collection system and treatment
works. Industrial sources include 9 Significant Industrial Users, 2 of which are Categorical
Industrial Users. The permit will continue to require the City to implement its pretreatment
program
INSTREAM MONITORING
The Muddy Creek WWTP discharges treated municipal wastewater to the Yadkin River, a
Class WS-IV water in the Yadkin -Pee Dee River basin. Instream monitoring is required for
BOD, NH3-N, temperature, dissolved oxygen, fecal coliform, and conductivity. The
permittee is provisionally exempted from the instream monitoring requirements based on
the participation in the Yadkin Pee -Dee Monitoring Coalition.

Re: Comments on Draft NPDES Permit
Muddy Creek WWTP (NC0050342)
City of Winston-Salem; Forsyth County
Dear Mr. Chernikov:
The City of Winston-Salem has reviewed the draft permit for the Muddy Creek WWTP.
The following items of concern were discussed with Mr. Tom Belnick, on June 10, 2009
via conference call. The City of Winston-Salem makes the following requests based on
past plant performance and budgetary concerns.
• Chronic Toxicity- The City of Winston-Salem requests that in the future we be
allowed to perform toxicity sampling as a Pass/Fail, Single Dilution Test rather
than the current Multi-Concentration/Chronic Value method in an effort to
conserve limited monetary resources.
• Facility Location- This page shows the current 002 outfall in the wrong location.
See the attached documentation for the correct location.
• Mercury Limit- The effluent limitations and monitoring page indicates there will
be a weekly average limit for Hg of 0.2162 ug/1. All Hg testing for Muddy Creek
was conducted using high level mercury testing EPA method 245.1. Most of the
resulting values are below the minimum detectable level of 0.20ug/1. The City of
Winston-Salem would agree to 12 months of conditional monitoring using the
low level test EPA method 1631E and then recalculate the RPA. We would also

agree to a monitoring frequency of 2/month, placing both Muddy Creek and
Archie Elledge plants on the same monitoring schedule. This will provide more
efficient scheduling and will help to conserve limited monetary resources.
We appreciate your review of these requests before the final permit becomes applicable.
If you have any concerns or comments you may contact Chris Shamel/ Assistant Utility
Plant Superintendent/ORC @ 336-784-4701.

City of Winston-Salem/Forsyth County
Dear Mr. Guerra,
This letter is regarding permit modification dated April 10, 2006 to relocate the 002
outfall at Muddy Creek WWTP. Construction to relocate the new 002 outfall is complete
and the old 002 overflow is permanently sealed as of 3pm on 9/17/2007.
The new 002 discharge is located at 3538 Frye Bridge Road (SR1493) where it crosses
Muddy Creek (Lat 35 deg 58' 36" Long 80 deg 58' 36"). The new outfall is ready for
service should a severe weather event require it to be placed into service. This should
satisfy the requirements of the permit modification dated April 10, 2006. Please contact
me at [phone] with any questions concerning this matter.

For mercury, I understand how you concluded that no daily maximum was needed based on your
RPA. Based on that conclusion, the only limit you have is a weekly average.However, 40
CFR
Part 122.45(d)(2) requires that all POTWs contain both monthly average andweekly average
limits.
Adding either a monthly average or daily maximum limit equal to the weeky average limit would
be acceptable. `

Re: Request for NPDES Permit Renewal
Muddy Creek WWTP (NC0054342)
City of Winston-Salem
The City of Winston-Salem requests the simple renewal of the NPDES permit for Muddy
Creek WWTP (NC0050342). The current permit expires on June 30th, 2009. There is no
increase in flow capacity being requested at this time and should remain at the current 21
MGD limit. The application and supporting documentation requested in your February
29th, 2008 letter are attached.
There have been many upgrades/changes to Muddy Creek since the last permit renewal in
2004. Please see the changes listed below:
• South Fork influent outfall carbon pellet odor scrubber.
• Fine Bubble Diffusers have been installed in all three aeration basins.
• A 44 ton capacity hydrated lime silo has been added at the Primary Clarifier
effluent that provides alkalinity control to the aeration basins.
• A 2000 KW generator has been added in addition to the existing 1240 KW
generator to provide 100% electrical operational capacity to the plant.
• An Effluent/Flood control pump station has been added to prevent the Yadkin
River from backing up into the plant during high water weather events. Along
with this the secondary outfall (002) has been relocated further down stream to
allow for adequate chlorine contact time when this outfall is activated and provide
better access for sampling during such weather events. The 002 outfall flow will
also be de -chlorinated with Sodium Bisulfite. See map in section "B" to see actual
location of new 002 outfall.

• The plant SCADA system has been upgraded to Wonderware to provide better
operation control of equipment and process monitoring.
• A 5.2 mile biosolids pipeline is in place between Muddy Creek WWTP and
Archie Elledge WWTP that sends digested biosolids there for disposal. Ferric
Chloride and Dispersant tanks have been added for struvite control during the
biosolids transfer between the two plants.
Please contact Mr. Chris Shamel @ [phone] with any questions regarding the
content of the application.

Winston-Salem/Forsyth County Utility Commission
Archie Elledge WWTP (NPDES Permit NC0037834)
Muddy Creek WWTP (NPDES Permit NC0050342)
Sludges from the Utility Commission's two wastewater treatment plants are anaerobically
digested to meet Class B criteria established by EPA's 40CFR Part 503 Regulations.
Anaerobic digestion occurs by subjecting the sludges to times and temperatures that meet
PSRP requirements. Both the Archie Elledge and Muddy Creek plants have lagoons for
storage and dewatering of liquid biosolids to approximately 5.0% solids for land
application. The Commission currently disposes of its Class B biosolids under the North
Carolina Division of Water Quality Land Application of Residuals Permit WQ0000094.
Stabilized biosolids from the anaerobic digestion process at Muddy Creek are now being
pumped 5.2 miles into two blending tanks at Archie Elledge WWTP. Three 8" HDPE
pipe lines are utilized to pump biosolids between each facility. One line is for biosolids
from the Muddy Creek plant to the Elledge plant, the second line brings centrate from
Elledge Plant centrifuges back to Muddy Creek Lagoons, and the third is a spare line.
The Muddy Creek digested biosolids are pumped into the blending tanks along with the
biosolids from Archie Elledge's anaerobic digesters. The blend of biosolids is then
centrifuged into cake biosolids of approximately 22% solids and is available for land
application as a Class B material or for landfill disposal.
The newest addition to the biosolids handing system (3/2008) is the Andritz biosolids
dryer. Cake biosolids from the centrifuges are fed into the dryer to produce a 90-93%
solids dry pellet. This is a Class "EQ" biosolids and is disposed of by land application
through a contractor or may be disposed of by other approved methods. The North
Carolina Division of Water Quality permit number for this facility is WQ0029804.
In summary, there are several biosolids disposal options for Winston-Salem. The
preferred method is distribution of class A pelletized biosolids. The next option would be
to land apply liquid or cake biosolids and the least likely method would be to landfill
cake or pelletized biosolids.
