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. The six (6) existing monitor wells must be sampled initially prior to waste disposal operations and thereafter every April, August, and December for the following parameters: NO3 (10.0) Ammonia Nitrogen TDS (500.0) TOC pH (6.5-8.5 standard units) Water Level Chloride (250.0) Total Coliforms (1/100m1) Volatile Organic Compounds - In December Only (by method 1 or 2 below) Method 1: Method 6230D (Capillary - Column), "Standard Methods For The Examination of Water And Wastewater", 17th ed., 1989 Method 2: Method 502.2 " Methods For The Determination Of Organic Compounds In Drinking Water", U.S. EPA - 600/4-88/39 19 If any volatile organic compounds are detected by method 6230D, or the equivalent method 502.2, then EPA methods 604 and 611 must also be run to detect other organic compounds which may be present. The results of all analyses specified in the monitoring requirements, including 604 and 611 if required, must be submitted simultaneously. The measurement of water level must be made prior to sampling for the remaining parameters. The measuring points (top of well casing) of all monitoring wells shall be surveyed relative to mean sea level (M.S.L.). The depth of water in each well shall be measured from the surveyed point on the top of the casing. The water level elevations shall then be determined relative to M.S.L.. 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. 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 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 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 May, September, and January. 3. The Compliance Boundm)X delineated on the attached site plan (previous permit) 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. For facilities permitted on or after December 30, 1983, the Compliance Boundary is established at the lesser of 250 feet from the perimeter of the waste disposal area, or 50 feet within the property boundary. 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 Pen -nit. 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, 5 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. 4. The Lagoon/ pond liners (for the 5 -day and 50 -day minimum holding ponds) shall be installed in accordance with one of the following: The lagoon shall have a liner of natural material at least one (1) foot in thickness at all locations with a hydraulic conductivity of no greater than 1 x 10-6 centimeters per second when compacted. Following installation and inspection of the lagoon liner, and prior to waste disposal operations, verification of the liner's compliance with hydraulic conductivity and thickness specifications must be provided to the Division of Environmental Management, Groundwater Section, by the project engineer. The interior surfaces of the lagoon shall be completely lined with a 60 -mil thick liner. Following installation and inspection of the lagoon liner, and prior to waste disposal operations, certification of the liner's compliance with approved construction specifications and the liner's integrity must be provided to the Division of Environmental Management, Groundwater Section, by the project engineer. 5. The effluent storage lagoons shall not be excavated into bedrock. 6. No land application of waste activities shall be undertaken when the seasonal high water table is less than three feet below land surface. 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 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. 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.
