PERFORMANCE STANDARDS 1. The drip irrigation facilities shall be effectively maintained and operated at all times so that Ehere 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 perforin satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the wastewater, the Permittee shall take imuxtediate 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 groundwaters 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) 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, (] 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 drip 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 I.

No type of wastewater other than that from the Pisgah Center for Wildlife Education 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. Public access to the land application sites shall be controlled during active site use. Such controls may include the posting of signs showing the activities being conducted at each site. 11, Freeboard in the surface wetland cell shall not be less than one fool at any time. 111. MONITORING AND REPORTING REQUIREMENTS Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed necessary by the Division to insure surface and ground water protection will be established and an acceptable sampling reporting schedule shall be followed. 2. Adequate records shall be maintained by the Permittee tracking the amount of wastewater disposed. These records shall include, but are not necessarily limited to, the following information: Lt. date of irrigation, b. volume of wastewater irrigated, c. field irrigated, d. length of time field is irrigated, c. continuous weekly, monthly, and year-to-date hydraulic (inches/acre) loadings for each field, f. weather conditions, and g. maintenance of cover crops.

Daily average values shall be calculated by dividing monthly flow volume by the number of days in the month. 4. The effluent from the subject facilities shall be monitored by the Permittee at the point prior to irrigation every June and September for the following parameters: BOD5 TSS T� :' Fecal Coliform pH NH3 as N Three (3) copies of all operation and disposal records (as specified in condition Ili 2) on Form NDAR-1 and three (3) copies of all effluent monitoring data (as specified in condition III 3 and III 4) on Form NDMR-1 shall be submitted on or before the last day of the following month.
