PERFORMANCE STANDARDS The surface 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 there 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 groundwaters resulting from the operation of this facility. 3. 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. The following buffers shall be maintained: a) 400 feet between wetted area and any residence or places of public assembly tinder 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 drainage ways 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 lilies. 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. II.

The application rate shall not exceed a cumulative loading of 45.6 inches over any twelve (12) month period at an instantaneous application rate not to exceed 0.214 inches per hour. 8. No type of wastewater other than that from U.S. Naval Aerial Target Facilities at Piney Island (BT- 11) shall be irrigated 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 perfonned. 10.

If clogging results in excessive ponding of wasterwater, the filter sand must be removed and replaced as necessary. The sand must be maintained at a depth of at least 24 inches. III. MONITORING AND REPORTING REQUIREMENTS 1. 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. Influent flow shall be continuously monitored and daily average flow values shall be reported on Form NDMR. Flow may be estimated from water use records provided water use is metered.
