Facility Overview:
The Neilson WTP operates a conventional WTP designed for a potable flowrate of 48
MGD. The facility currently recycles all backwash and has a monitoring wavier in effect
since 2011. The application states the backwash will continue to be recycled until facility
upgrades are completed (estimated to be 2020 or 2021), which will add an equalization
basin and clarifier to process water for discharge through the permitted outfall and
processing residuals for land application, at which point discharge from the outfall will
commence.
Compliance History:
• No NOVs or enforcements between June 2014 and May 2019
• No toxicity test results available to review

RPA:
There is no data to run an RPA on. The facility currently recycles all backwash.
NCG59 General Permit Eligibility:
• There is no data available to run an RPA on, therefore it is not possible to
determine if limits are needed for any parameters
• There is no toxicity data available to evaluate
• Conclusion: They are not eligible for the NCG59
Changes from previous permit to draft:
• Updated eDMR footnote in A(1) and language as A(3)
• Updated outfall map
• Language on the Supplement to Permit Cover Sheet has been updated
• Components lists added on Supplement to Permit Cover Sheet based on the
permit renewal application
• Facility address on cover page and supplement to permit cover sheet updated
based on renewal application and BIMS
• Added facility grade in A(1)
• Added parameter units in A(1)
• Added hardness footnote in A(1) per the current WTP guidance
• Removed turbidity limits as receiving stream is not listed on the 2018 303(d) list
for turbidity, and monitoring reduced to 2/month per 2012 WTP guidance
• Removed footnote #3 stating "Parameters should be monitored in conjunction
with toxicity test" as this is no longer required per the 2012 WTP guidance
• Updated toxicity footnote to reflect removal of former footnote #3
• Updated tox test language in A(2) to language currently used
Changes from draft to final:
• None
Comments received on draft permit:
• Hannah Headrick (Aquatic tox; via email 8/9/19):
o Cover Letter and Page 1 — noticed that the address has been updated.
■ DWR Response: The address was corrected based on information
provided with the renewal application, as well as what was in
BIMS.
o Page 4 - It appears that a statement from the ATB templates for this type
of testing is missing from the explanation of Chronic Toxicity Monitoring:
If the Permittee monitors any pollutant more frequently than

•
required by this permit, the results of such monitoring shall be included in
the calculation and reporting of the data submitted on the DMR and all
AT Forms submitted.
Please clarify why this statement was not included on these pages. If this
was a simple omission, please include this statement on these pages of the
permit.
■ DWR Response: We use templates for the toxicity conditions in
permits. If it was not present in the permit, it's because it's not
present in the templates we use. If this should be included, all
toxicity language templates that we use will need to be updated.
Ron Boone (WSRO; via email 8/12/19): Looks good to me.
Bill Brewer (City of Winston Salem; via email 8/19/19): We have reviewed the
above referenced permit and do not have any comments or questions. The
language is consistent with our other two plants initial permit requirements.
Thanks for the opportunity to review.

The City of Winston-Salem formally requests renewal of NPDES Permit #NC0086011 at our
R.W. Neilson Water Treatment Plant. As requested and required this letter serves as notification
of our intention to renew this permit.
The Neilson Plant is currently operating under a discharge waiver as requested by David
Saunders on October 11, 2011 (letter attached). The City of Winston-Salem has contracted with
Black & Veatch International to design a major upgrade of this facility which is currently at 90%
completion. It is anticipated this project will be bid in March of 2019 and the construction phase
will last approximately 36 months. As part of the design, the facility will have an equalization
basin and clarifier added to process water for discharge through our permitted outfall. Prior to
any discharge my staff will notify the Winston-Salem regional office and upon discharge will
commence sampling for the discharge as stipulated to ensure compliance with the permit.
Should you have any questions regarding this matter please do not hesitate to call me at (336)

NPDES PERMIT APPLICATION - SHORT FORM C - WTP
For discharges associated with water treatment plants
S. Type of treatment plant:
® Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by
filtration and disinfection)
❑ Ion Exchange (Sodium Cycle Cationic ion exchange)
❑ Green Sand Filter (No sodium recharge)
❑ -Membrane Technology (RO, nanofiltration)
Check here if the treatment process also uses a water softener ❑
6. Description of source water(s) (i.e. groundwater., surface water)
The source for this facility is a low head dam and intake on the Yadkin River located at Idol's
Dam approximately 4 miles west of the plant.
7. Describe the treatment process(es) for the raw water:
Raw water from the Yadkin River is pumped to two raw water reservoirs (15 MG each for a total
of 30 MG of raw water storage). The raw water then flows by gravity into a 48.0 MG
conventional water treatment plant. Coagulation is achieved using aluminum sulfate followed
by flocculation, sedimentation and filtration. Sodium hypochlorite is added to the settled water
prior to filtration for disinfection. After filtration sodium hypochlorite is again added for
disinfection and to maintain chlorine residual. Zinc orthophosphate, hydrofluorosilicic acid and
caustic soda are added after filtration.
8. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
Three (3) waste station pumps [6.48 MGD each for pumping back wash water to head
of water plant treatment process]
Two (2) lagoon decant pumps [0.58 MGD each for pumping lagoon decant to waste
station]
Three (3) residuals lagoons [-2.1 MG's each]
Neilson's sedimentation basins are currently cleaned manually and the solids are sent straight
to one of three residuals lagoons. Water is decanted off the top of the lagoon in service and is
pumped to the waste station via one of two 0.58 MGD waste pumps. All filter back wash water
at the Neilson Plant is currently recycled back to the head of the water plant treatment process
via a waste pump station that contains three 4,500 MGD pumps. Due to this the NPDES
discharge point is currently inactive. Neilson is plant is currently at 90% design review of an
upgrade that will be bid in March 2019. This upgrade will include the addition of an
equalization basin and clarifier for treating process residuals for land application. When the
upgrade is completed the plant will no longer recycle water but will start to use the permitted
discharge point. This is anticipated to begin sometime in 2020 or 2021.

R.W. Neilson Water Treatment Plant
Solids Handling Plan
The Neilson Water Treatment Plant is a 48 MGD water treatment facility. Solids are
generated by manual sludge removal from sedimentation basins, backwashing filters, and
filter -to -waste after filter backwashes are completed. Solids produced from filter backwashes
and filter -to -waste is routed to a waste pump station and is then pumped to the head of the
water treatment process. Solids removed from the sedimentation basins are routed directly to
one of three residual lagoons.
Permits and Classifications:
1. The discharge from the residuals lagoons is authorized by NPDES Permit NC0086011.
The classification for the discharge is Grade 1 Physical/Chemical.
Operation:
1. The system consists of a waste station with (3) Fairbanks Morse single stage pumps rated
at 6.48 MGD each, (2) Fairbanks Morse basin sludge pumps rated at 1.0 MGD each, (2)
lagoon pumps rated at 0.65 MGD each and (3) residuals lagoons (3 lagoons at —2.0 MG).
Each residuals lagoon consists of an oval earthen lagoon with clay bottom.
2. Routine inspections of equipment will be conducted by Rodney Darr, Sr. Utility Plant
Supervisor, to ensure proper operation of equipment. Any equipment not functioning
properly will be reported through the water division's asset management program,
MAXIMO, to the appropriate support group for repair/replacement.
3. Backwash and filter -to -waste water from the plant process flows to the waste station and
then is pumped by the waste station pumps to raw water reservoir #2 at the head of the
plant treatment process.
4. All sedimentation basin and hopper blow downs are pumped by the basin sludge pumps
directly to one of three residuals lagoons.
5. The solids stream enters on one end of each lagoon and the decant is pumped from the
opposite end by the lagoon pumps to the waste station where it is returned to the head of
the treatment process.
6. Residuals lagoons are rotated with one cleaned and ready for use, one in service and one
drying at all times.
7. Residuals are removed from the lagoons and hauled to an application site which consists
of —31 acres on Cooper Road (about 1.0 mile from the Neilson WTP) by a private
contractor.
