Noncompliance Notification: The Permittee shall report by telephone to the Washington Regional Office, telephone no. 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 sludge digester; the known passage of a slug of hazardous substance through the facility; or any other unusual circumstances. 3 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 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. IV. GROUNDWATER REQUIREMENTS Any groundwater quality monitoring as deemed necessary by the Division of Environmental Management shall be provided. 2. Within 30 days of permit issuance, five (5) monitor wells, one (1) upgradient and one (1) downgradient of the spray field, and one (1) upgradient and two (2) downgradient of the lagoon must be installed to monitor groundwater quality. The location and construction details for these wells must be approved by the Washington Regional Office, from which a well construction permit must be obtained. 3. The monitor wells must be sampled initially after construction (and prior to waste disposal operations) and thereafter every March, July, and November for the following parameters: NO3 (10.0) TDS (500.0) pH (6.5 - 8.5 standard units) Chloride (250.0) TOX (in November only) Ammonia Nitrogen TOC Water Level Total Coliforms (1/100 ml) The measurement of water level must be made prior to sampling for the remaining parameters. 4. 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. 5. if TOC concentrations greater than 10 mg/1 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 background monitor well exceeds 10 rng/l, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient well$ shall be subject to the additional sampling and analysis as described above. 4 6. 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. 7. 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. 8, The Compliance Boundary delineated on the attached site plan for the disposal system is specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards applicable to the groundwater of North Carolina. An exceedance of Groundwater Quality Standards beyond the Compliance Boundary is subject to penalty provisions applicable under General Statute 143-215.6(1)a. The sale of property, by the Permittee, which is within or contiguous to the disposal system site may alter location of the Compliance Boundary. 9. For facilities permitted on or after December 30, 1983, the Compliance Boundary is established at the lesser of 250 feet from the lagoon and sprayfields, or 50 feet within the property boundary. 10. 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. 11. The REVIEW BOUNDARY for the disposal system is specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A REVIEW BOUNDARY 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. 12. The wastewater lagoon will be lined by the following materials: L Six inches, (minimum, in all locations) of natural clay, compacted sufficiently so as to achieve a maximum permeability of 1 x 10 to the seven eml sec will be installed, upon which ii. A synthetic liner ( proposed thickness of 12 mil) will be installed, upon which iii. Three inches of screened local soil will be placed to provide protection for the synthetic liner. Following installation and inspection, verification of the thickness and permeability of the natural clay liner should be provided to the Department by the project engineer. 13. Oil drained from engine crankcases or degreasing solvents wastes shall not be discharged into the disposal system. 6-1 V. INSPECTIONS 1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to insure proper operation of the subject facilities. 2.
