The ten (10) existing monitoring wells and any new monitoring wells shall be sampled every March, July, and November for the following parameters: NO3 (10.0) TOC pH ( 6.5-8.5 standard units) Chlorides (250.0) Water Level TDS (500.0) Ammonia Nitrogen Orhtophosphate Total Coliforms (1/100 ml) 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 relative to mean sea level (M.S.L.). The depth of the water in each well shall be measured from the surveyed point on the top of the casing. The water level elevations shall then be determined relative to (M.S.L.). 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 back rg_otand 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 method 604 and 611 must also be run to detect other organic compounds which may be present. The results of all analyses specified in the monitoring requirements, including 604 and 611 if required, must be submitted simultaneously. The results of the sampling and analysis shall be sent to the N.C. Division of Environmental Management on Form GW-59 (Compliance Monitoring Report Form) every April, August, and December 2. The Qompliance,Boundary delineated on the attached site plan for the disposal system is specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards applicable to the groundwater of North Carolina. An exceedance r;", 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 the rotary distributors permitted prior to December 30, 1983, the Compliance Boundary is established at a distance of 500 feet from the from the edge of the rotary distributor fields, or the property boundary, whichever is less. For the rotary distributors permitted on or after December 30, 1983, the Compliance Boundary is established at the lesser of 250 feet from the edge of the rotary distributor fields, or 50 feet within the property boundary. 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. All rotary distributors shall have a minimum of one (1) downgradient monitoring well installed prior to the start of waste disposal operations for the distributor in question. The well(s) shall be constructed such that the water level is never above or below the screened (open) portion of the well at any time during year. The exact location and construction details for all the wells shall be approved by the Washington Regional Office, from which a well construction permit must be obtained. All monitoring wells shall be sampled initially after construction and thereafter every March, July, and November for those parameters specified for the existing monitoring wells. 4.
