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

The final permit includes the following changes from the draft permit sent to you on May 12,2004:
D The TRC limit added to the draft permit takes effect February 1,2006. If you wish to install dechlorination
equipment,consult the enclosed guidance document.
D The instream monitoring for turbidity has been replaced with a turbidity effluent limit of 50 NTU,as you requested.
D Your request for a higher TRC limit cannot be granted,given the existing discharge location. However,this permit
does include a reopener condition for the TRC limit. In order to receive a higher TRC limit,the City must either:
• designate the"dry ditch"as an effluent channel under the restrictions of 15A NCAC.0228,or
D. pipe the effluent to the main channel of Muddy Creek.
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

Please take notice that this permit is not transferable. The Division may require modification (or revocation
and reissuance)of the permit. This permit does not affect the legal requirements to obtain other permits that may be
required by the Division of Water Quality or permits required by the Division of Land Resources,Coastal Area
Management Act,or any other Federal or Local governmental permits may be required. If you have any questions or

A. (2) TOTAL RESIDUAL CHLORINE (TRC) REOPENER
This permit may be reopened for revision of the TRC limit if the Permittee completes one of the following actions.
a. This permit may be reopened if the existing dry ditch between the outfall and Muddy Creek is designated
as an effluent channel [per 15A NCAC 02B.0228]. To receive this designation, the Permittee must
submit documentation to the Division that shows the dry ditch:
> Is contained entirely on property owned (or otherwise controlled)by the Permittee

Dear Mr. Weaver,
These comments are in reference to your letter dated May 12, 2004 and received by the
City of Winston-Salem on May 20, 2004 regarding the renewal of NPDES Permit#
NC0086011 for the Neilson Water Treatment Plant located at 5725 Frye Bridge Road,
Clemmons,NC 27012. In regards to this draft permit the City of Winston-Salem
respectfully requests the following permit modifications:
1. The unnamed tributary that our discharge fed into is a dry streambed and our
discharge is in effect the only flow feeding into this creek bed. This unnamed
tributary flows into Muddy Creek. In light of this we request that our discharge total
residual chlorine limit be based upon the flow of Muddy Creek and raised from 17
ug/L to 28 ug/L. . In addition,the practical quantitation limit (PQL) for total residual
chlorine is 20 ug/L. Below this amount we cannot reliably prepare standards to verify
trace amounts of chlorine. The error associated with such low level measurements
may also be great enough to cause us to violate our permit, when in fact we are not
truly reading residual chlorine but interferences with the method.
2. In addition, the City of Winston-Salem requests a turbidity limit of 50 NTU on this
discharge in lieu of the upstream and downstream turbidity sampling requirements
currently required. Due to the fact that we are the headwater of this unnamed
tributary, this will simplify our monitoring requirements.

Dear Mrs. Stephens,
The City of Winston-Salem is requesting renewal of NPDES Permit#NC00860611 at our
Neilson Water Treatment Plant. As requested and required this letter describes the
Neilson Water Treatment Plant sludge management plan.
The Neilson Water Treatment Plant has three residuals lagoons located on the property.
Residual alum sludge from the facilities settling basins is drained into these lagoons. The
plant has a schedule by which it drains hoppers (weekly) and by which it drains and
cleans solids from the settling basins (quarterly). Once a residuals lagoon becomes full, it
is taken out of service and the solids are allowed to dry for several months. Once dried,
the solids are removed from the lagoon by a front loader and hauled approximately 2
miles from the plant and land applied to an area the City of Winston-Salem has permitted
off Cooper Road.
Should you have any questions regarding this matter please feel free to call me at(336)
727-8418.
Sinc- OOP,'
David K. 'aunders
Director of Utilities
