Monitor Wells CPW-1S, CPW-2D, CPW-3D, CPW-4D, CPW-5S, CPW-5D, CPW-6S, CPW-6D, CPW-7S, CPW -7D, CPW-8S, CPW-8D, CPW-9S, CPW-9D, CPW-10S, CPW-10D, CPW-12S, CPW-12D, CPW-13S, CPW-13D, CPW-14S, CPW-14D, and CPW-15D shall be sampled every March, July, and November for the following parameters: pH Water Level Chloride Total Dissolved Solids Iron Chromium 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 every April, August, and December. 2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. 3. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L, Groundwater Classifications and Standards. 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). The sale of property by the Permittee which is within or contiguous to the disposal system site may alter the location of the Compliance Boundary. For Quarry I Section I, which was permitted prior to December 31, 1983, the Compliance Boundary is established at a distance of 500 feet from the waste disposal boundary, or the property boundary, whichever is less. For Quarry I Section II, which was permitted on or after December 30, 1983, the Compliance Boundary fs established at the lessor of 250 feet from the waste disposal boundary, 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 Director within 14 days.- The Director shall then establish a modified Compliance Boundary which will be completed as a modification to the Permit. 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. 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 (1) 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 (2) submit a plan, for the alteration of existing site conditions, facility design and operational controls that will prevent a violation of standards at the Compliance Boundary, and implement that plan upon its approval by the Director. 4 V . INSPECTIONS The Permittee or his designee shall inspect the residuals storage, transport, 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 maintain 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.
