GROUNDWATER REQUIREMENTS The three (3) monitor wells, MW -1, MW -2, and MW -3, shall continue to be sampled every March, July, and November, for the following parameters: NO3 Ammonia Nitrogen TDS TOC pH Water Level Chloride Total Coliforms Copper Phenol Lead Zinc SO4 Arsenic Cadmium Chromium Iron Volatile Organic Compounds - In November only (by Method 1 or 2 below) Method 1: Method 6230D (Capillary - Column), "Standard Methods For The Examination of Water and Wastewater", 17th ed., 1989 Method 2: Method 502.2 "Methods For The Determination Of Organic Compounds In Drinking Water", U.S. EPA -600/4-881039 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. 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 the Asheville Regional Office Groundwater Supervisor, telephone number (704) 251-6208, must be contacted immediately for further instructions regarding any additional follow-up analyses required. The results of all initial and follow-up analyses must be submitted simultaneously. The results of the sampling and analysis shall be sent to the Groundwater Section, Permits and Compliance Unit, P.O. Box 29535 Raleigh, N.C. 27626-0535 on Form GW -59 [Compliance Monitoring Report Form] every April, August, and December. 2. Any 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. The Compliance Boundary for the disposal system constructed prior to December 31, 1983 is established at either (1) 500 feet from the waste disposal area, or (2) at 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). 5 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. INSPECTIONS 1. 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. This log of inspections shall be maintained by the Permittee for a period of five years from the date of the inspection and shall be made available to the Division of Environmental Management or other permitting authority, upon request. 2. Any duly authorized officer, employee, or representative of the Division of Environmental Management may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the surface disposal site or facility at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be kept under the terms and conditions of this permit; and may obtain samples of groundwater, surface water, or leachate.
