PERFORMANCE STANDARDS 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 certifiedyou 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 Land Application Unit, Division of Water Quality, 1636 Mail Service Center, Raleigh, NC 27699-1636. 2.

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. 3. 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 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, 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_ 5. 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. 6. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 7.

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. S. A Ieakage test shall be performed on the septic tank and dosing tank to insure that any exf ltration 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. 9. The sand media of the dual bed pressure dosed 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. 10. 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. 11. A sanitary tee and filter 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. 12.
