This permit shall be effective from the date of issuance until September 30, 1998, shall void Permit No. WQ0002519, which was issued on February 28, 1992, and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS 1. Upon completion of construction and prior to operation of this permitted facility, a certification must be received from a professional engineer certifying that the permitted facility has been installed in accordance with this permit and the approved plans and specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535. 2. The Washington Regional Office, phone no. 919/946-6481, shall be notified at least forty- eight (48) hours in advance of backfilling of the installed facilities so that an in -place inspection can be made. Such notification to the regional supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays. 1 3. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the Permittee shall take immediate corrective action, including those as may be required by this Division, such as construction of additional or replacement wastewater treatment or disposal facilities. 4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or groundwaters resulting from the operation of this facility. 5. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the facilities are installed, maintained, and operated in a manner which will protect the assigned water quality standards of the surface waters and ground waters. 6. Adequate measures shall be taken to divert stormwater from the disposal area and prevent wastewater runoff from the disposal area. 7. The residuals generated from these treatment facilities must be disposed of in accordance with General Statute 143-215.1 and in a manner approved by the North Carolina Division of Environmental Management. 8. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 9. The following buffers shall be maintained, except where alternate buffers are specifically described on the approved submittal documents: a) 100 feet between disposal area and any public or private water supply including wells b) 100 feet between disposal area and "SA and SB" classified surface waters c) 50 feet between disposal area and any stream, lake, river or natural drainageway d) 50 feet between disposal area and property lines e) 10 feet between disposal area and surface water interceptor drains or diversions (upslope) f) 25 feet between disposal area and surface water interceptor drains or diversions (downslope) and groundwater drainage systems. 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 facilities 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 1. The facilities shall be properly maintained and operated at all times. 2 2. Upon classification of the facility by the Certification Commission, the Permittee shall employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of the wastewater treatment facilities. The operator must hold a certificate of the type and grade at least equivalent to or greater than the classification assigned to the wastewater treatment facilities by the Certification Commission. The Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with the conditions of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and must properly manage and document daily operation and maintenance of the facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202. Once the facility is classified, the Permittee must submit a letter to the Certification Commission which designates the operator in responsible charge within thirty days after the wastewater treatment facilities are 50% complete. 3. The application rates to the land application area shall not exceed 0.93 GPD per square foot, or an application rate which will result in a discharge to surface waters, whichever is less. 4. The facilities shall be effectively maintained and operated as a non -discharge system to prevent the discharge of any wastewater resulting from the operation of this facility. 5. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while normal maintenance is being performed. 6. The screenings removed from the wastewater treatment plant shall be properly disposed in a sanitary landfill. 7. The Division of Environmental Management maintains the right to require that appropriate dual source, dual feed, or standby power provisions be included for these facilities, should one of these options become necessary for the protection of the health of the citizens of North Carolina or its natural resources. 8. The flow measurement device shall be calibrated annually by a representative of a firm which is routinely engaged in the calibration of flow measurement devices. Records of the calibration, including all information pertinent to the calibration, shall be available during any inspection by Division staff. 9. Diffusers shall be cleaned as needed to assure adequate aeration. Records of maintenance shall be maintained by the permittee. 10 The clarifier weir and scum baffle shall be cleaned as needed to assure adequate operation of the facility.

The Permittee shall keep an inspection log or summary including at least the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee. This log of inspections shall be maintained by the Permittee for a period of three years from the date of the inspection and shall be made available upon request to the Division of Environmental Management or other permitting authority. 3. Any duly authorized officer, employee, or representative of the Division of Environmental Management may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the disposal site and facility at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be kept under the terms and conditions of this permit; or may obtain samples of groundwater, surface water, or leachate. VI. GENERAL CONDITIONS 1. This permit shall become voidable unless the facilities are constructed in accordance with the conditions of this permit, the approved plans and specifications, and other supporting data. 2. This permit is effective only with respect to the nature and volume of wastes described in the application and other supporting data. 3. This permit is not transferable.
