This permit shall be effective from the date of issuance until December 31, 2003, and shall be subject to the following specified conditions and limitations: L 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, the approved plans and specifications, and other supporting materials. If this project is to be completed in phases and partially certified, you shall retain the responsibility to track further construction approved under the same permit, and shall provide a_final certificate of completion once the entire project has been completed. Mail the Certification to the Non -Discharge Permitting Unit, P.O. Box 29535, Raleigh, NC 27626-0535. 2. The Raleigh Regional Office, telephone number (919) 571-4700, shall be notified at least forty- eight (48) hours in advance of operation 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. The drip 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. 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. The sand media of the pressure -dosed, recirculating surface sand filter must comply with the Division's sand specifications. The engineer's certification will serve as evidence that these specifications have been met. A leakage test shall be performed on the septic tank and dosing tank to insure that any exfiltration occurs at a rate which does not exceed twenty (20) gallons per twenty-four (24) hours per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of compliance with this condition. If excavation into bedrock is required for the installation of the septic tank or sand filter, the pit shall be lined with a 10-mil synthetic liner. A sanitary tee shall be installed on the effluent pipe of the septic tank. The engineer's certification will serve as evidence that these specifications have been met. 9. 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. 10. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 11. The following buffers shall be maintained: a) 100 feet between wetted area and any residence or places of public assembly under separate ownership, b) 50 feet between wetted area and property lines, c) 100 feet between wetted area and wells, d) 50 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 treatment/storage units and any wells, and g) 50 feet between 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. 2 H. OPERATION AND MAINTENANCE REQUMEMENTS 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. 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 WPCSOCC. The Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with the conditions of 15A NCAC 8A .0202. The ORC of the facility must visit each Class I facility at least weekly and each Class 11, Ill, 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 15A NCAC 8A .0202. Once the facility is classified, the Permittee must submit a letter to the WPCSOCC which designates the operator in responsible charge within thirty days after the wastewater treatment facilities are 50% complete. A suitable year round vegetative cover shall be maintained. 4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that will cause runoff. 5. Adequate measures shall be taken to prevent wastewater runoff from the drip irrigation field. The application rate shall not exceed a cumulative loading of22.48 inches over any twelve (12) month period at an instantaneous application rate not to exceed 0.25 inches per hour. 7. 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. No type of wastewater other than that from the residence on Willowbend Plantation Lot 7 shall be emitted onto the irrigation area. 9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while normal maintenance is being performed. 10. The drip irrigation field shall be fenced with at least a two -strand wire fence. 11. The Permittee is responsible for the operation and maintenance of the entire treatment and disposal system including, but not limited to, the following items. a.

Any process unit failure, due to known or unknown reasons, that renders the facility incapable of adequate wastewater treatment, such as mechanical or electrical failures of pumps, emitters, etc.; or b. Any failure of a pumping station or treatment facility resulting in a by-pass directly to receiving waters without treatment of all or any portion of the influent to such station or facility; or c. Any event when the disposal pump manually or automatically operates despite the precipitation or soil moisture sensor circuit breakers. Persons reporting such occurrences by telephone shall also file a written report in letter form within five (5) days following first knowledge of the occurrence. This report must outline the actions taken or proposed to be taken to ensure that the problem does not recur. 4. The Permittee shall maintain a record of the number of times that the drip irrigation system disposes treated effluent during precipitation events and under conditions when the soil in the disposal field is saturated.
