This zone identification information can be provided on the map required by Condition I.1. 4. No later than six months prior to the expiration of this permit, the Permittee shall request renewal of this permit on official Division forms. Upon receipt of the request, the Division will review the adequacy of the facilities described therein, and if warranted, will extend the permit for such period of time and under such conditions and limitations as it may deem appropriate. Please note that Rule 15A NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal application. II. PERFORMANCE STANDARDS The reclaimed water utilization facilities shall be effectively maintained and operated at all times so that there is no discharge to the surface waters, nor any contamination of ground waters, which will render them unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions or failure of the utilization area to adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including those actions that may be required by the Division of Water Quality (Division), such as the construction of additional or replacement wastewater treatment and disposal facilities. 2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to ground or surface waters resulting from the operation of this facility. 3. All wells that are constructed for purposes of groundwater monitoring shall be constructed in accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water Supply) and any other state and local laws and regulations pertaining to well construction. 4. Effluent limitations shall not exceed those specified in Attachment A. Application rate(s), whether hydraulic, nutrient, or other pollutant shall not exceed those specified in Attachment B. 6. The COMPLIANCE and REVIEW BOUNDARIES for the reclaimed utilization system are established at the property boundary. Any exceedance of standards at the Compliance or Review Boundary shall require action in accordance with 15A NCAC 02L .0106. 7. The Permittee shall apply for a permit modification prior to any sale or transfer of property that affects a compliance -boundary to establish a new compliance boundary. 8. In accordance with 15A NCAC 02L .0107(d), no wells, other than monitoring wells, shall be constructed within the compliance boundary except as provided by 15A NCAC 02L ,0107(g). WQ0023693 Version 1.3 Shell Version 070320 Page 4 of 12 9.

Some of the buffers specified above may not have been included in previous permits for this waste treatment and disposal system. These buffers are not intended to prohibit or prevent modifications, which are required by the Division, to improve performance of the existing treatment facility. These buffers do, however, apply to modifications of the treatment and disposal facilities that are for the purpose of increasing the flow that is tributary to the facility. These buffers do apply to any expansion or modification of the irrigation areas and apply in instances in which the sale of property would cause any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The applicant is advised that any modifications to the existing facilities will require a permit modification. ' The storage/irrigation ponds located at Winding River Plantation do not comply with this condition, but were previously approved by the Division. Therefore, this condition does not apply to those previously constructed ponds 10. The following shall be requirements for the reclaimed water distribution, storage, and utilization facilities: a.

Jersion 1.3 Attachment C — 'age 2 of 3 1. 3 X year monitoring shall be conducted in March, July & November; Annual monitoring shall be conducted every November. 2. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining parameters. 3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well_ The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum. 4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods: a. Standard Method 6230D, PQL at 0.5 µg/L or less b. Standard Method 621 OD, PQL at 0.5 µg/L or less c. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less e. Another method with prior approval by the Aquifer Protection Section Chief Any method used must meet the following qualifications a. A laboratory must be DWQ certified to run any method used. b. The method used merit, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D. c. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by the D WQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported. 5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office Aquifer Protection Supervisor, telephone number (910) 796-7215 must be contacted immediately for further instructions regarding any additional follow-up analyses required. 6. If TOC concentrations greater than 10 mg/1 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. Monitoring wells shall be reported consistent with the nomenclature and location information provided in this attachment. WQ0023693 Version 1.3 Attachment C Page 3 of 3
