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 render 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. d. Any time that self-monitoring information indicates that the facility has gone out of compliance with its permit limitations. Persons reporting such occurrences by telephone shall also file a written report in letter form within 1.5 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 reoccur. 5 IV. GROUNDWATER REQUIREMENTS 1. Any groundwater quality monitoring as deemed necessary by the Division of Environmental Management shall be provided. 2. The three (3) existing monitor wells must be sampled every March, July, and November for the following parameters: Nitrate pH Total Ammonia TOC TDS Chloride Water Levels Total Coliforms Orthophosphate TOX (in November only) The measurement of water level must be made prior to sampling for the remaining parameters. The analytical methods used for TOX must be capable of detecting the total of all halogenated organic compounds present at a concentration of 5.0 parts per billion (ppb) or greater. In the event that a TOX concentration of 5.0 ppb or greater is detected, any individual halogenated organic compound(s) present at a concentration at or above the method detection limit (MDL) must be identified and quantified utilizing EPA methods 601, 602, 604, and 611. If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the back r� monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. The numbers in parentheses represent the maximum allowable concentrations in groundwater for the various analytical parameters, as specified in 15 NCAC 2L [Groundwater Classifications and Standards]. Unless otherwise noted, the concentrations are given in parts per million. The results of the sampling and analysis shall be sent to the N.C. Division of Environmental Management on Form GW -59 (Compliance Monitoring Report Form) every April, August, and December. For facilities permitted prior to December 30, 1983, the Compliance Boundary is established at a distance 250 feet from the disposal fields, or the property boundary, whichever is less. If the title to any property which may affect the location of the Compliance Boundary is changed, the permittee shall notify the Division Director within 14 days. The Director shall then establish a modified Compliance Boundary which will be done as a modification to the Permit. 6' The REVIEW B ARY for the disposal system is specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A REVIEW BQUNDARY is established around disposal systems midway between the Compliance Boundary and the perimeter of the waste disposal area. When the concentration of any substance equals or exceeds the maximum allowable concentration of that substance at the REVIEW BOUNDARY, as determined by monitoring, the permittee shall either (i) demonstrate, through predictive calculations or modeling, that natural site conditions, facility design and operational controls will prevent a violation of standards at the Compliance Boundary; or, (ii) submit a plan for the alteration of existing site conditions, facility design or operational controls that will prevent a violation of standards at the Compliance Boundary, and implement that plan upon its approval by the Director. 3. Any additional groundwater quality monitoring as deemed necessary by the Division shall be provided. V. INSPE I N 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 wastewater treatment and disposal 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 keep 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. This log of inspections shall be maintained by the Permittee for a period of three years from the date of the inspection and shall be made available upon request to the Division of Environmental Management or other permitting authority. 3. Any duly authorized officer, employee, or representative of the Division of Environmental Management may, upon presentation of credentials, enter and 'inspect any property, premises or place on or related to the disposal site and facility at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be kept under the terms and conditions of this permit; or may obtain samples of groundwater, surface water, or leachate. VI. GENERAL CONDMON5 This permit shall become voidable unless the facilities are constructed in accordance with the conditions of this permit, the approved plans, specifications and other supporting data. 2. This permit is effective only with respect to the nature and volume of wastes described in the application and other supporting data. 7 3. This permit is not transferable. 1n the event there is desire for the facilities to change ownership, or there is a name change of the Permittee, a formal permit request must be submitted to the Division of Environmental Management accompanied by an application fee, documentation from the parties involved, and other supporting materials as may be appropriate. The approval of this request will be considered on its merits and may or may not be approved. 4. Prior to any transfer of this land, a notice shall be given to the new owner that gives full details of the materials applied or incorporated at this site. 5. A set of approved plans and specifications previously approved for the subject project must be retained by the applicant for the life of the project. 6. The annual administering and compliance fee must be paid by the Permittee within thirty (30) days after being billed by the Division. Failure to pay the fee accordingly may cause the Division to initiate action to revoke this permit as specified by 15 NCAC 211.0205 (c)(4). 7. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee to an enforcement action by the Division of Environmental Management in accordance with North Carolina General Statute 143-215.6. 8. The wastewater treatment facility shall connect to a publicly owned areawide sewage collection system within 180 days of its availability. All discharge of wastewater to the low pressure pipe distribution system shall cease at the time of the connection to the sewer system. 4. The issuance of this permit does not preclude the Permittee from complying with any and all statutes, rules, regulations, or ordinances which may be imposed by other government agencies (local, state, and federal) which have jurisdiction. 10. A automatically activated stand by power unit shall be maintained on site at all times. 11. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its extension. Upon receipt of the request, the Commission will review the adequacy of the facilities described therein, and if warranted, will extend the permit for such period of time and under such conditions and limitations as it may deem appropriate.
