Within 90 days of permit issuance, an upgradient monitor well shall be installed to monitor groundwater quality. The well(s) 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. The general location and name for each well is marked on Attachment A. Each monitoring well shall be located at the review boundary, constructed in accordance with this permit, and approved by the Washington Regional Office. 2. The well shall be constructed by either a North Carolina Certified Well Contractor, the property owner, or the property lessee according to General Statutes 87-94.4(b)(2). If the construction is not performed by a certified well contractor, the property owner or the lessee must physically perform the actual well construction activities, and the well(s) shall be constructed in accordance with 15A NCAC 2C .0108 (Standards of Construction for Wells Other than Water Supply) and any other state and local laws and regulations pertaining to well construction. 3. The Washington Regional Office, telephone number (252) 946-6481, 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. 4. Within thirty (30) days of 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-1 forms to the Permits and Compliance Unit, Groundwater Section, 1636 Mail Service Center, Raleigh, NC, 27699-1636. 5. Existing monitor wells MW-land MW-2 and the new monitor well MW-3 shall be sampled initially after construction and thereafter every March, July and November for the following parameters: Water Level Chloride Fecal Coliform Nitrate -Nitrogen (NO3-N) Total Phosphorous pH Total Dissolved Solids (TDS) Total Organic Carbon (TOC) Total Ammonia 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 treasuring 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. 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 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 form along with attached copies of the laboratory analyses. The updated forms can be downloaded using the following internet website: lltcp://�-7w.enr.state.nc.us/. 7. The permittee shall report any monitoring or other information which indicates that any contaminant may cause an endangerment to an underground source of drinking water and any noncompliance with a permit condition of malfunction of the treatment, disposal and lagoon system, which may cause fluid migration beyond the review boundary or lagoon perimeter. The information shall be provided to the Washington Regional Office (252-946-6481) orally within 8 hours of the occurrence and as a written submission within five days of the occurrence. The written submission shall contain a description of the noncompliance and its cause, the period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue, and any steps taken or planned to reduce, eliminate and prevent reoccurrence of the noncompliance. 8. No application of waste activities shall be undertaken when the seasonal high water table is less than one (1) foot below land surface. Verification of the water table elevation can be confirmed by water level readings obtained from monitor well(s) near the site, or auger -boring which must 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 the ground water. 9. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. 10. 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. V.
