GROUNDWATER REQUIREMENTS Within ninety (90) days of permit issuance, monitoring wells MW-13, MW-17 and MW-18 shall be identified to monitor groundwater quality specifically for the spray irrigation system. The general location and name for each well is marked on Figure 1. 4 2. Monitor wells MW-13, MW-17 and MW-18 shall be sampled initially after construction and thereafter every June and December for the following parameters: Water Level pH Total Organic Carbon (TOC) Lead -- In December only using Standard Method 3030C preparation Volatile Organic Compounds - In December only using one of the following: (A) Standard Method 6230D, PQL at 0.5 ug/L or less (B) Standard Method 621 OD, PQL at 0.5 ug/L or less (C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or Iess (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 0.5 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 0.5 ug/L must be qualified (estimated) and reported. If any volatile organic compounds are detected by the methods listed, then the Mooresville Regional Office Groundwater Supervisor, telephone number (704) 663-1699, must be contacted immediately for further instructions regarding any additional follow-up analyses required. The results of all initial an-' follow-up analyses must be submitted simultaneously. 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. 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. Anyexceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. For the initial sampling of the wells, the permittee shall submit a copy of the GWA Form (Well Construction Record) with the Compliance Monitoring Form (GW-59) for each well to the Groundwater Section, Permits and Compliance Unit, 1636 Mail Service Center Raleigh, N.C. 27699-1636. Initial Compliance Monitoring Forms that do not include copies of the WQ_1 form may be returned to the perrnitee without being processed. Failure to submit these forms as required by this permit may result in the initiation of enforcement activities pursuant to NC General Statutes 143-215.6A. 6. 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 followin the sampling month. 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. Anyexceedance of standards at the Review Boundary shall require remediation action on the part of the permittee. 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 stormwater 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. ThePermittee 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.

GENERAL CONDITIONS This permit shall become voidable unless the facilities are constructed in accordance with the conditions of this permit, the approved plans and 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. 3. This permit is not transferable. In the event there is a 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 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. Failure to abide by the conditions and limitations contained in this permit may subject thePermittee to an enforcement action by the Division in accordance with North Carolina General Statute 143-215.6A to 143- 215.6C. 6 The issuance of this permit does not exempt the Permittee from complying with any and all statutes, rules, regulations, or ordinances which may be imposed by other government agencies (local, state, and federa" which have jurisdiction, including but not limited to applicable river buffer rules in 15A NCAC 2B .026 erosion and sedirrientation control requirements in 15A NCAC Ch. 4 and under the Division's General Permit NCG0100000, and any requirements pertaining to wetlands under 15A NCAC 2B .0200 and 2H .0500. 6.
