This permit shall be effective from the date of issuance until January 31, 2009, shall void Permit No. WQ0002519 issued September 15, 1998, and shall be subject to the following specified conditions and limitations: 1. PERFORMANCE STANDARDS 1. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, 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 or disposal facilities. 2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or ground waters resulting from the operation of this facility. 3. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the facilities are installed, maintained, and operated in a manner which will protect the assigned water quality standards of the surface waters and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. 4. Adequate measures shall be taken to divert stormwater from the high rate infiltration area and to prevent wastewater runoff. 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, The following buffers shall be maintained: a. 100 feet between disposal area and any private or public water supply source including wells, b. 100 feet froze mean high water between disposal area and any "SA" or "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), and 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 high rate infiltration 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 The facilities shall be properly maintained and operated at all times. 2. Upon classification of the wastewater treatment and spray irrigation facilities by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201.
