Within 90 days of permit issuance one (1) downgradient monitor well shall be installed to monitor groundwater quality. 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. However, the exact location and construction details for these wells shall be approved by the Wilmington Regional Office, from which a well construction permit must be obtained. 2. The monitor wells shall be sampled initially after construction and thereafter every March, July, and November for the following parameters: NO3 TOC Ammonia Nitrogen Water Level Total Suspended Solids Volatile Organic Compounds - TDS pH Chloride Total Phosphorous In November only ( by Method 1 or Method 2 below) 1`Rw*i. ,. aR i...a win r ■ a",i _ r 1,,,,,n1 "4ran aryl finds for the r1GUJod lrictaivu .,2 .,,s. �..r,..lar~, of um..,, _d__ _ Methods _ _ 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 well. These elevations shall be provided to the Regioal Hydrogeologist within 60 days after well construction. The depth of water in each well shall be measured from the surveyed point on the top of the casing. 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/1, 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 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. 19 3. The Compliance 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 of Groundwater Quality Standards beyond the Compliance Boundary is subject to penalty provisions applicable under General Statute 143-215.6A. 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 on or after December 30, 1983, the Compliance Boundary is established at the lesser of 250 feet from the rotary distributors or 50 feet within the property boundary. 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 BQ.INDARY for the disposal system is specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A IEW BQUNDARY 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 RE V IE W BQUNDARY, 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. 4, Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. V . INSPECTIONS 1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to insure proper operation of the subject facilities. 2.
