JAY ZIMMERMAN Director February 9, 2016 RON HARGROVE — DIRECTOR OF UTILITIES WINSTON-SALEM/FORSYTH COUNTY UTILITIES COMMISSION POST OFFICE BOX 2511 WINSTON-SALEM, NORTH CAROLINA 27102 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.

The Permittee shall not distribute Class A Water Treatment Plant residuals that have a sodium 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.

Any approved variations to the acceptable soil pH (6.0) will be noted in this permit; i. If the land does not have an established vegetative cover unless the residuals are incorporated or injected within a 24-hour period following a residuals land application event.
