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 #
NCO079821 for the R. A. Thomas Water Treatment Plant located at 1201 Martin Luther
King Jr. Boulevard, Winston-Salem NC 27102. In regards to this draft permit the City of
Winston-Salem respectfully requests the following permit modification:
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. This will simplify our monitoring requirements and make it safer for our
operators to collect the sample due to the current upstream and downstream sample
sites having limited access.
Should you have any questions regarding this matter please do not hesitate to call me at
[phone].

Re: Renewal Notice

R.A. Thomas WTP
Forsyth County
Dear Mrs. Stephens,
The City of Winston-Salem is requesting renewal of NPDES Permit #NC0079821 at out
R.A. Thomas Water Treatment Plant. As requested and required this letter describes the
R.A. Thomas Water Treatment Plant sludge management plan.
The R.A. Thomas Water Treatment Plant has two residuals lagoons (designated Lagoons
#1 and #2) located on the property. Residual alum sludge from the facilities six settling
basins is normally drained into Lagoon 1. The plant has a schedule by which it drains
and cleans solids from the settling basins (every 2-3 months). Once Lagoon #1 becomes
full, it is taken out of service and drained. The solids are then pumped from Lagoon #1
by a screw type pump to an area adjacent to the lagoons and allowed to dry.
Filter backwash water from the plants process activities is sent to Lagoon #2. The
residuals from Lagoon #2 are handled in the same manner. Once Lagoon #2 becomes
full, the residuals are pumped via a screw type pump to an area adjacent the lagoons and
allowed to dry.
Should you have any questions regarding this matter please feel free to call me at (336)
727-8418.
