The five existing monitor wells shall continue to be sampled every March, July, and November for the following parameters: NO3 (10.0) TDS..(500.0) TOC pH ( 6.5-8.5 standard units) Ammonia Nitrogen Chloride (250.0) Water Level Fecal Coliforms (1/100 ml) Total Suspended Solids Volatile Organic Compounds - In November only (by Method 1 or Method 2 below) , Method 1: Method 6230D (Capillary - Column), "Standard Methods for the Examination of Water and Wastewater", 17th edition, 1989 Method 2: Method 502.2 " Methods for the Determination of Organic Compounds in Drinking Water", United States Environmental Protection Agency - 600/4-88/039 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 to provide relative elevations of the measuring point for each of the monitoring wells. The depth of water in each well shall be measured from the surveyed point on the top of the casing. 5 y; .. .. � _ '.::.'�, f. .... .. C 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. 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 analysis specified in the monitoring requirements, including 004 and 611 if required, must be submitted simultaneously The results of the sampling and anal�sis shall be sent to the N.C. Division of Environmental Management on Form. GW-59 (Compliance Monitoring Report Form) every April, August, and December, r 2. The Compliance Boundary for the disposal system is specified by regulations in 15 NCAC 2L, Classifications and Watet 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 before December 30, 1983, the Compliance Boundary is established at a distance 500 feet from the wastewater disposal facility, or the property boundary, whichever is less. 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 Permit. 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, 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. 3. Any additional groundwater quality monitoring as deemed necessary by the Division of Environmental Management shall be provided. 9 C L. V . INSPECTIONS 1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to insure proper operation of the subject facilities. 2.
