Resources and considered a part of this permit. This permit shall be effective from the date of issuance until April 30, 1996, and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS 1. The Winston-Salem Regional Office, phone no. (919) 761-2351, shall be notified at least twenty-four (24) hours after land application of the contaminated soil so that an inspection can be made. Such notification to the regional supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays. 2. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the facilities are installed, maintained, and operated in a manner which will protect the assigned water quality standards of the surface waters and ground waters. 3. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the Permittee shall take immediate corrective action, including those as may be required by this Division, such as the construction of additional or replacement treatment or disposal facilities. 4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or groundwaters resulting from the operation of this facility. 5 . The following buffers shall be maintained: a) 100 feet between disposal area and any public or private water supply including wells b) 100 feet between disposal area and "SA and SB" classified surface waters c) 50 feet between disposal area and any stream, lake, river or natural drainageway d) 50 feet between disposal area and property lines c) 10 feet between disposal area and surface water interceptor drains or diversions (upslope) f) 25 feet between disposal area and surface water interceptor drains or diversions (downslope) and groundwater drainage systems. 6. No contaminated soil other than that from 809 Randolph Street, Thomasville shall be placed on the land disposal site. H. OPERATION AND MAINTENANCE RE 1REMENTS 1. ' The facilities shall be properly maintained and operated at all times. 2. Upon classification of the facility by the Certification Commission, the Permittee shall employ a certified wastewater treatment plant operator to be in responsible charge of the wastewater treatment facilities. The operator must hold a certificate of the type and grade at least equivalent to the classification assigned to the wastewater treatment facilities by the Certification Commission. Once the facility is classified, the Permittee must submit a letter to the Certification Commission which designates the operator in responsible charge. 3. Adequate measures shall be taken to prevent surface runoff from carrying any disposed material into any surface waters. A diversion ditch shall be created to divert any rainfall away from the remediation area and a silt fence or catch basin shall be located down slope of the remediation area to catch any sediment runoff. 4. The 250 cubic yards of contaminated soil shall be spread to a thickness not to exceed three inches on at least 0.62 acres of land at the disposal site. 5. The facilities shall be effectively maintained and operated as a non -discharge system to prevent the discharge of any wastewater resulting from the operation of this facility. 6. The site shall be adequately limed to a soil pH of at least 6.5 prior to disposal of the contaminated soil. The contaminated soil and lime shall be thoroughly incorporated into the top six to eight inches of the native soils by tilling or disking. 7. To ensure that sufficient oxygen is provided for waste biodegradation, the site shall be retilled at periods of one month, two months, and every six months thereafter following disposal. 8. No food -chain crops shall be grown on the landfarming sites for at least two years following the completion of contaminated soil application and remediation. 9. Nutrients, in the form of nitrogen and phosphorus fertilizers, must be applied over the disposal area and fully incorporated into the mixed contaminated and native soil layer. To provide maximum benefits, fertilization should occur no sooner than 15 days nor later than 30 days subsequent to disposal. 2 Rate of fertilizer application should be the lesser of the following: a) For nitrogen, the tolerance level of the vegetative crop, as determined by a knowledgeable party, or 75-100 pounds per acre plant available nitrogen (PAN). b) For phosphorus, the tolerance level of the vegetative crop, as determined by a knowledgeable party, or 50-75 pounds per acre P205 (or equivalent). 10. All foreign debris shall be removed from the petroleum contaminated soil prior to land application and at no time shall foreign debris be land applied with the petroleum contaminated soils. III. MONITORING AND REPORTING. REQUIREMENTS Any monitoring deemed necessary by the Division of Environmental Management to insure surface and ground water protection will be established and an acceptable sampling reporting schedule shall be followed. 2. Noncompliance Notification: The Permittee shall report by telephone to the Winston-Salem, Regional Office telephone no. (919) 761-2351, 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 discharge of wastes to receiving waters. c. Any time that self-monitoring information indicates that the facility is not in 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 contaminated soil 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. IV. GROUNDWATER REQUIREMENTS 1. Any groundwater quality monitoring as deemed necessary by the Division of Environmental Management shall be provided. 2. Soil samples will be collected, from a minimum of two (2) areas at the disposal site, at intervals of 6 months and 12 months following disposal. Each sample will be composed of the vertical column of soil, extending from land surface to the maximum depth of waste incorporation, collected by using a soil auger, Shelby tube or split -spoon sampler. Samples at each location will be thoroughly mixed and a representative portion analyzed, (by methods specified in Guidelines For Remediation Of Soil -Contamination By Petroleum available from the Division of Environmental Management) to determine the concentration of. (i) Petroleum Fuel Hydrocarbons; and, (ii) any Volatile Organic Aromatic (VOA) compounds present. THE SAMPLES TAKEN AT DIFFERENT LOCATIONS SHALL NOT BE MIXED TOGETHER TO GENERATE A SITE -WIDE COMPOSITE SAMPLE. A copy of the laboratory results of the soil analysis shall be submitted to the Winston-Salem Regional Office, to the attention of the Regional Hydrogeological Supervisor, within thirty (30) days of sample collection. 3. The Compliance Boundary for the disposal system is specked by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. An exceedance 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 the 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 remediation area, 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 DEM 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_UNDARY 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. V. INSPECTIONS 1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to insure proper operation of the subject facilities. 0 2. The Permittee or designee shall inspect the contaminated soil area to prevent any 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 to the Division of Environmental Management or other permitting authority. 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. VI. GENERAL CQNDITIONS 1. This permit shall become voidable unless the contaminated soil is disposed of in accordance with the conditions of this permit and the approved documents. 2. This permit is effective only with respect to the nature and volume of wastes described in the application and other supporting data. 3. This permit is not transferable. In the event there is a desire for the facilities to change ownership, or there is a name change of the Permittee, a formal permit request must be submitted to the Division of Environmental Management accompanied by an application fee, documentation from the parties involved, and other supporting materials as may be appropriate. The approval of this request will be considered on its merits and may or may not be approved. 4. In any future transfer of this land, a notice shall be given to the new owner that gives full details of the materials applied or incorporated at this site. 5.
