Noncompliance Notification: The Permittee shall report by telephone to the Asheville Regional Office, telephone number (704) 251-6208, as soon as possible, but in no case more than 24 hours or on the next working day following the occurrence or first knowledge of the occurrence of any of the following: a. Any occurrence with the land application program which results in the land application of significant amounts of wastes which are abnormal in quantity or characteristic. b. Any failure of the land application program resulting in a release of sludge material to receiving waters. c. Any time that self-monitoring information indicates that the facility has gone out of compliance with the conditions and limitations of this permit or the parameters on which the system was designed. d. Any process unit failure, due to known or unknown reasons, that render the facility incapable of adequate sludge treatment. e. Any spillage or discharge from a vehicle or piping system transporting sludge to the application site. Persons reporting such occurrences by telephone shall also file a written report in letter form within 15 days following first knowledge of the occurrence. This report must outline the actions taken or proposed to be taken to ensure that the problem does not recur. 6 I V . GROUNDWATER REQUIREMENTS 1. At least 24 hours prior to the application of sludge to the site, the three (3) existing monitor wells (M77 f 1, MW77 f 2 and MW77 f 3) shall be sampled to establish ambient conditions and thereafter every March, July and November for two (2) years after any application for the following parameters: NO3 TOC Ammonia Nitrogen Water Level Total Suspended Solids Zinc Iron Volatile Organic Compounds - TDS pH Chloride Total Coliforms SO4 Oil & Grease annually (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 depth of 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 relative elevations of the measuring point for each monitor 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 back rground 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 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 Post Office Box 29535 Raleigh, N.C. 27626-0535 on Form GW -59 (Compliance Monitoring Report Form) every December. 2. The Compliance Boundary delinated on the attached site map for the disposal system is specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is established at either (1) 250 feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is closet to the waste disposal area. An exceedance of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate remediation action on addition to the penalty provisions applicable under General Statute 143-215.6(1)a. 7 Also in accordance with 15A NCAC 2L, a REVIEW BOUNDARY, delineated on the attached site map, 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. 3. No land application of waste activities shall be undertaken when the seasonal -high water table is less than three feet below land surface. 4. Any groundwater quality monitoring as deemed necessary by the Division of Environmental Management shall be provided. �MIRK11411 ►W The Permittee or his designee shall inspect the sludge 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 keep 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 three years from the date of the inspection and shall be made available upon request by the Division of Environmental Management or other permitting authority. 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 disposal site and 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; or may obtain samples of groundwater, surface water, or leachate.
