This permit shall be effective from the date of issuance until August 31, 2005, shall void Permit No. WQ0004972 issued February 6, 1996, and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS L The spray irrigation 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 irrigation 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 surface or groundwater resulting from the operation of this facility. The residuals generated from these treatment facilities must be disposed in accordance with General Statute 143-215.1 and in a manner approved by the Division. 4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 5. The following buffers shall be maintained: a) 400 feet between wetted area and any residence or places of public assembly under separate ownership, b) 150 feet between wetted area and property lines, c) 100 feet between wetted area and wells, d) 100 feet between wetted area and drainageways or surface water bodies, e) 50 feet between wetted area and public right of ways, f) 100 feet between wastewater treatment units and wells, and g) 50 feet between wastewater treatment units and property lines. 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 which 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 spray 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. II. OPERATION AND MAINTENANCE REQUIREMENTS The facilities shall be properly maintained and operated at all times. 2. Upon classification of the facility by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of the wastewater treatment facilities.

(2) The method used must, at a minimum, include all the constituents listed in Table VHI of Standard Method 6230D. (3) The method used must provided a PQL at 0.5 ug/L or less which must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL at 0.5 ug/L must be qualified (estimated) and reported_ If any volatile organic compounds are detected by the methods fisted, then the Winston-Salem Regional Office Groundwater Supervisor, telephone number (336) 7714600, must be contacted immediately for further instructions regarding any additional follow-up analyses required. The results of all initial and follow-up analyses must be submitted simultaneously. The measurement of water levels must be made prior to sampling for the remaining parameters. The depth to water in each well shall be treasured from the surveyed point on the top of the casing. 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. 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. The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality Monitoring: Compliance Report Form) by the Groundwater Section, Permits and Compliance Unit, 1636 Mail Service Center Raleigh, N.C. 27699-1636 on or before the last working day of the month following the sampling month. 2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
