PERFORMANCE STANDARDS 1. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the facilities are installed, maintained, and operated in a manner which will protect the assigned water quality standards of the surface waters and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. 2. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the Permittee shall take immediate corrective action, including those actions that may be required by this Division, such as the construction of additional or replacement treatment or disposal facilities. 3. 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. 4. Any residuals generated from these treatment facilities must be disposed in accordance with General Statute 143-215.1 and in a manner approved by the North Carolina Division of Environmental Management. 5. Diversion or bypassing of the untreated groundwater from the treatment facilities is prohibited. II. OPERATION AND MAINTENANCE REQUIREMENTS 1. The facilities shall be properly maintained and operated at all times. 2. Upon classification of the facility by the Certification Commission, 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 Certification Commission. The Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with the conditions of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at least weekly and each Class H, III, 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 Title 15A, Chapter 8A, .0202. 3. 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. III. MONITORING AND REP RTING REQUIREMENTS 1.

Noncompliance Notification: The Permittee shall report by telephone to the Washington Regional Office, telephone number 919/ 946-6481 as soon as possible, but in no case more than 24 hours or on the next working day following the occurrence or first knowledge of the occurrence of any of the following: a. Any occurrence at the wastewater treatment facility which results in the treatment of significant amounts of wastes which are abnormal in quantity or characteristic, such as the dumping of the contents of a basin or tank, the known passage of a slug of hazardous substance through the facility, or any other unusual circumstances; b. 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, aerators, compressors, etc.; c. Any failure of a pumping station, sewer line, 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 d. Any time that self -monitoring information indicates that the facility is not in compliance with its permit limitations. Persons reporting such occurrences by telephone shall also file a written report in letter form within 15 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. 2 IV. GROUNDWATER REQ111REMENTS 1.

The influent and effluent from the treatment system shall be sampled every March and September for the parameters specified below: Method 602 MTBE Orthophosphate Nitrate 3. In order to track nutrient movement in groundwater, the individual recovery wells must be sampled for the following parameters: Phosphate NO3 4. The measurement of water levels must be made prior to sampling for the remaining parameters. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. 5. The results of the sampling and analysis shall be sent to the Groundwater Section, Permits and Compliance Unit, P.Q. Box 29535 Raleigh, N.C. 27626-0535 on Form GW-59 [Compliance Monitoring Report Form] every April and October. 6.

If it is determined that the system is malfunctioning, all repairs should be made as soon as possible and reported to the Washington Regional Office within 48 hours. 8. The groundwater treatment system shall consistently achieve at least a 95% treatment efficiency (i.e. remove 95% of the influent contaminants) prior to discharge to the injection wells. If the treatment system fails to consistently achieve this standard, additional treatment units or changes in operational methods, may be required. 9. The COMPLIANCE,. BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is for the disposal system constructed after December 31, 1983 is established at either (1) 250 feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate remediation action in addition to the penalty provisions applicable under General Statute 143-215,6A(a)(1). In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems midway between the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance of standards at the Review Boundary shall require remediation action on the part of the permittee. 10. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. V . INSPECTIONS 1. Adequate inspection, maintenance and cleaning shall be provided by the Permittee to insure proper operation of the subject facilities. 2. The Permittee or his designee shall inspect the groundwater recovery and treatment facilities to prevent malfunctions and deterioration, operator errors and discharges which may cause or lead to the release of wastes to the environment, a threat to human health, or a nuisance. The Permittee shall maintain an inspection log or summary including at least the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee.
