GROUNDWATER _REQUIREMENTS Within sixty (60) days of permit reissuance, one (1) monitor well, downgradient of the spray field on the Review Boundary at the western corner of the spray field (see attached map) must be installed to monitor groundwater quality. This well will be called MW-3. The well shall be constructed such that the water level in the well is never above or below the screened (open) portion of the well at any time during the year. Each monitoring well shall be located at the review boundary, constructed in accordance with this permit, and approved by the Mooresville Regional Office. 2. The new monitor well MW-3 shall be sampled initially after construction, and also with the currently active monitor wells MW-1 and MW-2, shall be sampled every April, and MW-3 by the spray field is also to be sampled within 30 days after each spray field event for the following parameters: Total Dissolved Solids Fecal Coliforms pH Water Level 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_ 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, P.O. Box 29578 Raleigh, N.C. 27626-0578 on or before the last day of May, and within 30 days after sampling of any spray field event. 4 3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. 4. The CQMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary for the disposal system constructed prior to December 31, 1993 is established at either (1) 500 feet from the waste disposal area, or (2) at 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. 5. All wells that are constructed for purposes of groundwater monitoring shall be constructed in accordance with 15A NCAC 2C A108 (Standards of Construction for Wells Other than Water Supply) and any other state and local laws and regulations pertaining to well construction. 6. The Mooresville Regional Office, telephone number (704) 663-1699, shall be notified at least forty-eight (48) hours prior to the construction of any monitoring well so that an inspection can be made of the monitoring well location. Such notification to the regional groundwater supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding state holidays. 7. Within ninety (90) days of permit issuance, the permittee shall submit two original copies of a scaled topographic map (scale no greater than V:100') signed and sealed by a state licensed land surveyor that indicates all of the following information: a. the location and identity of each monitoring well, b . the location of the waste disposal system, c_ the location of all property boundaries, d . the latitude and longitude of the established horizontal control monument, e. the relative elevation of the top of the well casing (which shall be known as the "measuring point"), and f. the depth of water below the measuring point at the time the measuring point is established. The survey shall be conducted using approved practices outlined in North Carolina General Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56. The surveyor shall establish a horizontal control monument on the property of the waste disposal system and determine the latitude and longitude of this horizontal control monument to a horizontal positional accuracy of +/- 10 feet. All other features listed in a. through e_ above shall be surveyed relative to this horizontal control monument. The positional accuracy of features listed in a. through e. above shall have a ratio of precision not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of the survey. Any features located by the radial method will be located from a minimum of two points. Horizontal control monument shall be installed in such a manner and made of such materials that the monument will not be destroyed due to activities that may take place on the property. The map shall also be surveyed using the North American Datum of 1983 coordinate system and shall indicate the datum on the map. All bearings or azimuths shall be based on either the true or NAD 83 grid meridian. If a Global Positioning System (GPS) is used to determine the latitude and longitude of the horizontal control monument, a GPS receiver that has the capability to perform differential GPS shall be used and all data collected by the GPS receiver will be differentially corrected. 5 The maps and any supporting documentation shall be sent to the Groundwater Section, N.C. Division of Water Quality P.O. Box 29578 Raleigh, N.C. 27626-0578. 8. Upon completion of all well construction activities, a certification must be received from a professional engineer certifying that the monitoring wells are located and constructed in accordance with the Well Construction Standards (15A NCAC 2C) and this permit. This certification should be submitted with copies of the Well Completion Form (GW-1) for each well. Mail this certification and the associated GW- I forms to the Permits and Compliance Unit, Groundwater Section, P.O. Box 29578, Raleigh, NC, 27626-0578. 9. For the initial sampling of the well as specified elsewhere in the permit, the permittee shall submit a copy of the GW-1 Form (Well Completion Form) with the Compliance Monitoring Form (GW-59) for that well. Compliance Monitoring Forms that do not include copies of the GW-1 form will be returned to the permittee 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 143-215.6. V . INSPECTIONS 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 Water Quality or other permitting authority. 3. Any duly authorized officer, employee, or representative of the Division of Water Quality 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 leachate.
