Renewal Summary
This renewal contains the following changes:
• Added the facility grade to Section A. (1.).
• Updated the effluent table in Section A. (1.) with eDMR parameter codes.
• Updated Section A. (3) to reflect current federal requirements for Electronic Reporting of
Discharge Monitoring Reports.
• Many limits noted as stricter than what was calculated on IWC in Section A. (1.) parameters were
not changed to determine compliance with antidegradation policy [ 15A NCAC 02B .0201 ]
• Added effluent monitoring for turbidity to determine compliance with 15A NCAC 02B.0211 (21).
Compliance History
Last enforcement was 2012. Only 1 NOV in the last 5 years, and it was due to UV system malfunctioning.
Last inspection in 2020 found site to be in compliance.

Sample Locations: E = Effluent, I — Influent. U = 0.1 Mile (at bridge) upstream from
outfall. D = 0.08 miles downstream at bridge. .
Effluent turbidity shall not cause receiving -stream turbidity to exceed 10 NTU. If background
turbidity naturally exceeds 10 NTU, the effluent shall not cause background turbidity to
increase. Exceeding this permit limit will require sufficient instream sampling (upstream
and/or downstream) to verify compliance (effluent vs. background) [NCAC 02B. 0211 (21)].
See Condition A. (2.) for instructions should the facility's permitted UV system fail and an alternate
means of disinfection is required. Total Residual Chlorine monitoring requirements and limits are
applicable if chlorine compounds are used for disinfection.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN

A.(2.) TEMPORARY MEANS OF DISINFECTION
[G.S. 143-215, 143-215.1]
a. In the event that the wastewater treatment plant's ultraviolet (UV) disinfection system fails,
underperforms, or is removed from effective service, the permittee or his agent shall immediately inform
the Winston Salem Regional Office of this development and discuss temporary, alternate means for
disinfection of the effluent.
b. If chlorine compounds are used as temporary means of disinfection, the total residual chlorine (TRC)
concentration of the effluent shall be monitored daily while this method of disinfection is in use and
values shall be reported on the discharge monitoring report. TRC in the effluent shall not exceed
28µg/L; therefore, dechlorination methods may also be necessary to ensure protection of water quality in
the receiving stream.
c. In the event that TRC monitoring should occur, the Division shall cNsider all effluent TRC values
reported below 50 µg/L to be in compliance with the permit. However, the Permittee shall continue to
record and submit all values reported by a North Carolina certtied laboratory (including field certified),
even if these values fall below 50 µg/L. .
d. Use of a disinfection system other than the permitted syste during instances not deemed as
emergency and/or temporary (replacement of lamp p c mg or maintenance, etc.) will be
considered a violation of the terms of this permit.
A.(3.) ELECTRONIC REPORTING - DISCH ITORING REPORTS
