GROUNDWATER REQUIREMENTS Monitor wells MW -4, MW -5, and MW -6, shall be sampled. every June for the parameters listed below. Prior to sampling the parameters, the measurement of water levels must be taken. 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 relative to a common datum. Water Level pH (field) Chloride Total Dissolved Solids (TDS) Fecal Coliforms Total Organic Carbon (TOC) Nitrate (NO3-N) Total Ammonia Nitrogen (NH3-N) Total Phosphorus Volatile Organic Compounds - using one of the following: (A) Standard Method 6230D, PQL at 0.5 ug/L or less (B) Standard Method 6210D, PQL at 0.5 ug/L or less (C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less (D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less (E) Another method with prior approval by the Groundwater Section. Chief Any method used must meet the following qualifications: (1) A laboratory must be DWQ certified to run any method used. (2) The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D. (3) The method used must provided a PQL at OS ug/L or less which must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL at OS ug/L must be qualified (estimated) and reported. If TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring well (MW -5 and MW -6), 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 (MW -4) 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. All reports and documentation (GW -1, GW -30, GW -59) shall be mailed to the following address: Groundwater Section Permits and Compliance Unit 1636 Mail Service Center Raleigh, NC 27699-1636 Updated blank forms (GW -1, GW -30, GW -59) may be downloaded from. the Groundwater Section's website at bttp.//gw.phnr.statc.nc.us/ or requested from the address mentioned above. The results of the sampling and analysis must be received on Form GW -59 (Groundwater Quality Monitoring: Compliance Report Form) by the Groundwater Section, Permits and Compliance Unit, 1636 Mail Service Center, Raleigh, N.C. 27699-1636 on or before the last working day of the month following the sampling month. The data of all groundwater sampling analyses required by the permit conditions must be reported using the most recent GW -59 for along with attached copies of the laboratory analyses. 2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. 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. 4. Waste application activities should not occur when the vertical separation between depth of application and the water table is at less than three (3) feet. Verification of the water table elevation can be confirmed by water level readings obtained from the monitor well(s) near the site or auger boring(s), which trust be done within 24 hours, prior to application of wastewater. Any open borings must be properly filled with native soil, prior to application to decrease the chance of any waste contaminating groundwater. S. The storage basin shall have either a liner of natural material at least one (1) foot in thickness and having a hydraulic conductivity of no greater than 1 x IV centimeters per second when compacted, or a synthetic liner of sufficient thickness to exhibit structural integrity and an effective hydraulic conductivity no greater than that of the natural material liner, according to 15A NCAC 2H .0219(0.

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 or other permitting authority. Any duly authorized officer, employee, or representative of the Division may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the disposal site or facility at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be maintained under the terms and conditions of this permit, and may obtain samples of groundwater, surface water, or Ieachate.
