Mr. Struve:
As requested the Division reviewed the proposed Muddy Creek Temporary Pump Station as well as the planned
addition of the South Fork Influent Diversion Box at the Muddy Creek WWTP NC0050342. Based on the
information provided, no compromise of the Muddy Creek WWTP operational integrity or minimum design
standards was noted. It was stated the on -site temporary pump stations operations will be retired in conjunction
with completion of the approved Authorization to Construct permit 050342A05. Therefore, the Division deems
the temporary pump stations and addition of the diversion box covered by the existing permit 050342A05, and
no further permitting is necessary.
A statement indicating the temporary pump stations were retired and the diversion box was installed is to be
written by the signing party on the Engineer Certificate form as confirmation these items were completed. I
recommend a copy of this email be attached to Winston-Salem CORRECTED Authorization to Construct
permit 050342A05 issued August 1, 2014 for future reference.
If you have any questions you can contact Ron Berry at [phone] or ron.berry@a,ncdenr.gov.

SUBJECT:
CORRECTED Authorization to Construct
A to C No. 050342A05
City of Winston-Salem
Muddy Creek WWTP
Dear Mr. Hargrove:
The initial letter of request for an Authorization to Construct was received March 26, 2014, by
the Division of Water Resources (Division), and the A to . C permit was issued July 3, 2014. The
Division was advised by Black & Veatch on July 29, 2014 that subsequent changes/corrections as the
result of the reduction in influent flow from the loss of Davie County wastewater, the availability of
alternative emergency power from the recently approved CHP project, and other noted corrections
were requested for the issued A to C permit 050342A05.
The submitted revised design, specifications, and corrections for the A to C permit 050342A05
project have been reviewed and revisions/corrections applied where appropriate in this CORRECTED
A to C permit 050342A05. The CHP project is independent of the A to C permit construction, and its
completion is anticipated prior to the completion of the A to C permit 050342A05 construction. As a
mandatory requirement to provide stand-by power for the additional electrical load, the 2,000 KW
diesel generator narrative must remain in the A to C permit. Upon completion of the CHP project and
connection to the Muddy Creek WWTP electrical grid, the CORRECTED A to C permit 050342A05
Engineer Certificate narrative should be edited by the signing party prior to submittal to the Division to
reflect the substitution of the CHP project for the listed stand-by diesel generator system.
Authorization is hereby granted for the construction of modifications as corrected to the
existing 21 MGD Muddy Creek WWTP, with discharge of treated wastewater into the Yadkin River
in the Yadkin -Pee Dee River Basin.
