Companies, EXP., LLC. 4100 US Highway 29 Greensboro, North Carolina 27214 Dear Mr. Redmond: John E. Skvarla, Ill Secretary Subject: Permit No, WQ0002838 Deerhurst Mobile Home Park W WTF Wastewater Irrigation System Wake County In accordance with your permit renewal request received August 15, 2014, we are forwarding herewith Permit No. WQ0002838 dated December 10, 2014, to Yes Communities Exp, LLC. for the continued operation of the subject wastewater treatment and irrigation facilities. Please note that this renewed permit shall become effective on February 1, 2015 (i.e. the day after the expiration date of the existing permit), which differs from the date of this letter. This permit shall be effective from February 1, 2015 until January 31, 2020, shall void Permit No. WQ0002838 issued September 7, 2012 and shall be subject to the conditions and limitations as specified therein. Please pay particular attention to the monitoring requirements listed in Attachments A, B and C 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. For your convenience, customized electronic copies of your facility's NDMR, and NDAR-1 reporting forms are available for download at: http:i/portal.ncdenr.orwweb/wq/aps/lau/reporting. It was noted during an inspection by the Raleigh Regional Office that there is a large discrepancy between the influent and effluent flow meter readings. As required by Condition IV.3, the Permittee shall install and maintain an appropriate flow measurement device to ensure the accuracy and reliability of flow measurement consistent with accepted engineering and scientific practices. These devices shall be calibrated at a minimum of once per year and the Permittee shall maintain records of flow measurement device calibration on file for a period of at least five years. If the discrepancy is verified after the meters have been calibrated, then the Permittee needs to develop a plan to correct the intrusion of groundwater at the lagoon if that is found to be the source of the discrepancy.

If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/L, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. 7.
