Dear Mr. Hargrove:
Subject: Permit No. WQ0031314
P. W. Swann WTP
Distribution of Class A Water
Treatment Plant Residuals
Forsyth County
In accordance with your permit renewal request received December 2, 2015, we are forwarding
herewith Permit No. WQ0031314 dated February 9, 2016, to Winston-Salem/Forsyth County Utilities
Commission for the continued operation of the subject residuals management program. Please note that
this renewed permit shall become effective on March 1, 2016 (i.e. the day after the expiration date of the
existing permit).
This permit shall be effective from March 1, 2016, until February 28, 2021, shall void Permit No.
WQ0031314 issued November 30, 2012, and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements listed in Attachment A for they may
differ from the previous permit issuance. Failure to establish an adequate system for collecting and
maintaining the required operational information shall result in future compliance problems.
Please note the following permit conditions are new since the last permit issuance dated
November 30, 2012:
➢ Condition III.9. — There are new provisions for the utilization agreement compared to Old
Condition I11.9., e.g., can be dissolved at request of those receiving residuals or sale of land;
the length of agreement is up to parties concerned. Read carefully.
➢ Condition 111.13. —Similar to Old Condition 11I.13., but now if the Permittee knows that those
receiving residuals are over -applying, the Permittee shall report this to the Winston-Salem
Regional Office.
There was a request to remove Condition 11I.8.h. from the Permit, i.e., the soil pH requirement.
The laboratory results showed that the pH of the residuals to be applied was less than 6.5. Because the pH
is this low, Condition III.81. remains in the permit even though it is water treatment plant residual being
applied.

adsorption ratio (SAR) of 10 or higher without prior written Division approval. The Permittee may
seek approval by demonstrating that the entity accepting the residuals is: aware of the effects of a high
SAR content; has agreed on proper residual application rates; and has agreed to operational
considerations to ensure that the high SAR content will not adversely impact the receiving sites.
Recommendations regarding sodium application rate, soil amendments (e.g., gypsum, etc.) or a
mechanism for maintaining site integrity and conditions conducive to crop growth, can be obtained
from the local Cooperative Extension Office, the Department of Agriculture and Consumer Services,
the Natural Resource Conservation Service, a North Carolina Licensed Soil Scientist, or an agronomist.

b. Maintenance schedules;
c. Safety measures;
d. SpilI response plan;
e. Inspection plan including the following information:

Fluctuation in temperature, flow, and other operating conditions can affect the quality of the
residuals gathered during a particular sampling event. The sampling plan shall account for any
foreseen fluctuations in residuals quality and indicate the most limiting times for residuals to
meet pathogen reduction requirements (e.g. facilities that land apply multiple times per year
but have an annual sampling frequency, may need to sample during winter months when
pathogen reduction is most likely to be negatively affected by cold temperatures).

[15A NCAC 02T .0120]
The Permittee shall pay the annual fee within 30 days after being billed by the Division. Failure to pay
