Stevens cc: Randolph County Health Department Winston-Salem Regional Office, Water Quality Section Winston-Salem Regional Office, Groundwater Section Groundwater Section, Central Office Technical Assistance and Certification Unit Non -Discharge Compliance/Enforcement Unit NORTH CAROLINA ENVIRONMENTAL MANAGEMENT COMMISSION DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES RALEIGH SURFACE DISPOSAL UNIT PERMIT In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended, and other applicable Laws, Rules, and Regulations PERMISSION IS HEREBY GRANTED TO Town of Ramseur Randolph County FOR THE continued operation of a surface disposal unit consisting of a 10-acre lined lagoon and the associated piping for the disposal of up to 60 dry tons per year (i.e., not to exceed five dry tons per month) of lime -stabilized wastewater residuals from the source listed in Condition Il. 2. with no discharge of wastes to the surface waters pursuant to the application received on October 10, 1999 as well as the additional information received on February 10, 2000, June 8, 2000, and July 31, 2000 and in conformity with the project plans, specifications, and other supporting data subsequently filed and approved by the Department of Environment and Natural Resources and considered a part of this permit. This permit shall be effective from the date of issuance until September 30, 2005; shall void Permit No. WQ0010528, issued April 18, 1995; and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS Each surface disposal unit shall be effectively maintained and operated as a non -discharge system to prevent the discharge of any wastes resulting from the operation of this program. 2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or ground water resulting from the operation of this surface disposal unit. 3. In the event that the surface disposal unit is not operated satisfactorily, including the creation of nuisance conditions, the Permittee shall cease disposing of the residuals to the surface disposal unit, contact the Winston-Salem Regional Office, and take any immediate corrective actions as may be required by the Division of Water Quality (Division). 4. The following buffer zones shall be maintained: a. 400 feet between an active surface disposal unit and any habitable residence, b. 100 feet between an active surface disposal unit and any public or private water supply source, all streams classified as WS or B, waters classified as SA or SB and any Class I or Class II impounded reservoir used as a source of drinking water, Il. c. 100 feet between an active surface disposal unit and any stream, lake, river, or natural drainage way, d. 50 feet between an active surface disposal unit and property lines (if the original permit was issued with the buffer distance to property line as 100 feet, updated maps must be submitted and new acreage delineated for the buffer to be reduced), e. 10 feet between an active surface disposal unit and any interceptor drains or surface water diversions (upslope), f. 25 feet between an active surface disposal unit and any interceptor drains or surface water diversions (downslope), g. 25 feet between an active surface disposal unit and any groundwater lowering and surface drainage ditches. Some of the buffers specified above may not have been included in previous permits for this surface disposal unit. These buffers are not intended to prohibit or prevent modifications that are required by the Division to improve performance of the existing surface disposal unit. These buffers do, however, apply to modifications of the surface disposal unit. These buffers do also apply to any expansion or modification of the surface disposal unit and apply in instances in which the sale of property would cause any of the buffers now complied with, for the surface disposal unit, to be violated. The Percnittee is advised that any modifications to the existing surface disposal unit will require a permit modification. 5. A copy of this permit shall be maintained at the surface disposal unit site when residuals are being disposed during the life of this permit. A spill prevention and control plan shall be maintained in all residuals transport and application vehicles. 6. When wastewater residuals are disposed in a surface disposal unit, the Class A pathogen requirements in 40 CFR Part 503.32(a) or the Class B pathogen requirements in 40 CFR Part 503.32(b) and one of the vector attraction reduction requirements in 40 CFR Part 503.33 shall be met. Additionally, an evaluation shall be performed that demonstrated the residuals' ability to comply with this requirement. Upon request, a copy of this evaluation, including all test results and calculations, shall be submitted. OPERATION AND MAINTENANCE REQUIREMENTS 1. The facilities and the surface disposal unit shall be properly maintained and operated at all times. 2. No residuals other than the following shall be approved for disposal in the surface disposal unit in accordance with this permit: Source Countv Permit Number Volume Town of Ramseur WWTP Randolph NPDES Permit No. NCO026565 60 dry tons per years Lime -Stabilized Biosolids 5 dry tons per month' The rate of residuals application in the surface disposal unit shall not exceed five dry tons per month and 60 dry tons per year. The Permittee shall submit a formal request to and receive written approval from the Division should there be a desire to exceed these application rates. This requirement is being initiated as a result of the unknown integrity of the liner present in the surface disposal unit and the inability to utilize groundwater and/or surface water sampling to monitor the its performance. Limiting the rate of residuals application will prolong aerobic treatment of any organic matter present in the residuals, allow volatilization of ammonia from the residuals, and facilitate soil treatment of any leachate from the residuals. 2 The pollutant concentrations in the residuals that will be disposed in a surface disposal unit shall not exceed the following Ceiling Concentrations (i.e.,dry weight basis): Concentration Parameter milli rams per kilo ram Arsenic 39 Chromium 260 Nickel 270 4. Upon classification of the facility by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall employ a certified operator to be in responsible charge (ORC) of the surface disposal unit. The operator shall hold a certificate of the type classification assigned to the surface disposal unit by the WPCSOCC. The Permittee shall also employ a certified back-up operator of the appropriate type to comply with the conditions of 15A NCAC 8G .0202. 5. The active surface disposal unit shall not restrict the flow of a base flood. 6. The active surface disposal unit shall not be located in an unstable area. 7. Appropriate measures shall be taken to control public access to the surface disposal unit during active use and for the 36-month period following closure of the surface disposal unit. Such controls may include fencing and the posting of signs indicating the activities being conducted at each site. Adequate provisions shall be taken to prevent any surface runoff from occurring from any active surface disposal unit. If runoff cannot be prevented, a collection system shall be installed with the capacity to handle runoff from a 24-hour, 25-year storm event. Ail collected runoff shall be disposed in a manner approved by the Division. 9. Adequate provisions shall be taken to prevent wind erosion from conveying pollutants or residuals from the surface disposal unit onto the adjacent property or into any surface waters. 10. Food crops, feed crops, and/or fiber crops shall not be grown on an active surface disposal unit, unless approval has been requested and received from the Division. 11. Animals shall not be grazed on an active surface disposal unit, unless approval has been requested and received from the Division. III. MONITORING AND REPORTING REQUIREMENTS Any monitoring (i.e., including groundwater, surface water, residuals, soil, or plant tissue analyses) deemed necessary by the Division to insure protection of the environment shall be established and an acceptable sampling and reporting schedule shall be followed. 2. Proper records shall be maintained by the Permittee tracking all disposal activities. All records shall be kept by the Permittee for a minimum period of five years from the date of disposal. These records shall include, but shall not necessarily be Iimited to the following information: a. Source of residuals; b. Rate of residuals disposed in dry tons per month; and c. Volume of residuals disposed in gallons per year, dry tons per year, or kilograms per year. 3.

In addition, the EPA certification statements concerning compliance with pathogen requirements, vector attraction reduction requirements and management practices shall be completed annually by the proper authority or authorities if more than one is involved, either the person who prepares the residuals, the person who derives the material, or the person who applies the residuals. 6. Three copies of all required monitoring and reporting requirements as specified in Condition III. 1., Condition III. 2., Condition M. 3., Condition III. 4., and Condition III. 5. shall be submitted annually on or before March Ist of the year following the disposal event to the following address: NC Division of Water Quality Water Quality Section Non -Discharge Compliance/Enforcement Unit 1617 Mail Service Center Raleigh, North Carolina 27699-1617 7. Noncompliance Notification: The Permittee shall report by telephone to the Winston-Salem Regional Office, telephone number (336) 771-4600, 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 surface disposal activities that results in the disposal of significant amounts of wastes that are abnormal in quantity or characteristic. b. Any failure of the surface disposal activities resulting in a release of material to receiving waters. 4 c. Any time that self -monitoring information indicates that the surface disposal unit 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 renders the surface disposal unit incapable of adequate residual treatment. e. Any spillage or discharge from a vehicle or piping system transporting residuals to the surface disposal unit. Persons reporting such occurrences by telephone shall also file a written report in letterform within five 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. The COMPLIANCE BOUNDARY for the surface disposal unit is specified by regulations in 15A NCAC 2L (i.e., Groundwater Classifications and Standards). The Compliance Boundary for surface disposal units constructed after to December 31, 1983 is established at either (1) 250 feet from the surface disposal unit or (2) 50 feet within the property boundary, whichever is closest to the surface disposal unit. 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 NCGS §143-215.6A(a)(1). In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the surface disposal unit midway between the Compliance Boundary -and the perimeter of the surface disposal unit. Any exceedance of Groundwater Quality Standards at the Review Boundary shall require remediation action on the part of the Permittee. 2. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided. 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_ 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 or other permitting authority, upon request. 2. Any duly authorized officer, employee, or representative of the Division may, upon presentation of credentials, enter and inspect any property, premises, or place on or related to the surface disposal unit at any reasonable time for the purpose of determining compliance with this permit; inspect or copy any records that must be kept under the terms and conditions of this permit; and obtain samples of groundwater, surface water, or leachate. VI. GENERAL CONDITIONS 1.
