This permit shall be effective from the date of issuance, until November 30, 2006, shall void Permit No. WQ0012521, issued October 9, 1996, and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS 1. Within 90 days of permit re -issuance, the Permittee is fully responsible for properly abandoning and sealing the water supply well located to the east of Sprayfield Plot 1B (as indicated on Attachment A), near the "tenant house." The proper abandonment procedure shall be in accordance with 15A NCAC 2C .0113. Upon completion of all well abandonment activities, a certification must be received from a professional engineer certifying that the wells are properly abandoned in accordance with current regulations. Mail three copies of this certification, and any associated documentation to the Permits and Compliance Unit, Groundwater Section, 1636 Mail Service Center, Raleigh, NC, 27699-1636. 2. The spray irrigation facilities shall be effectively maintained and operated at all times so that there is no discharge to the surface waters, nor any contamination of ground waters which will render them unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to adequately assirnilate the wastewater, the Permittee shall take immediate corrective actions including those actions that may be required by the Division of Water Quality (Division), such as the construction of additional or replacement wastewater treatment and disposal facilities. 3. 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. 4. The residuals generated from these treatment facilities must be disposed in accordance with North Carolina General Statute 143-215.1 and in a manner approved by the Division. 5. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 6. The following buffers shall be maintained: a) 400 feet between wetted area and any residence or places of public assembly under separate ownership, b) 150 feet between wetted area and property lines, c) 100 feet between wetted area and wells, d) 100 feet between wetted area and drainageways or surface water bodies, e) 50 feet between wetted area and public right of ways, f) 100 feet between wastewater treatment units and wells, and g) 50 feet between wastewater treatment units and property lines. Some of the buffers specified above may not have been included in previous permits for this waste treatment and disposal system. These buffers are not intended to prohibit or prevent modifications, which are required by the Division, to improve performance of the existing treatment facility. These buffers do, however, apply to modifications of the treatment and disposal facilities which are for the purpose of increasing the flow that is tributary to the facility. These buffers do apply to any expansion or modification of the spray irrigation areas and apply in instances in which the sale of property would cause any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The applicant is advised that any modifications to the existing facilities will require a permit modification. Il. OPERATION AND MAINTENANCE REQUIREMENTS The facilities shall be properly maintained and operated at all times. 2. Upon classification of the facility by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of the wastewater treatment facilities. The operator must hold a certificate of the type and grade at least equivalent to or greater than the classification assigned to the wastewater treatment facilities by the WPCSOCC. The Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with the conditions of 15A NCAC SG .0202. The ORC of the facility must visit each Class I facility at least weekly and each Class H, III, and IV facility at least daily, excluding weekends and holidays, and must properly manage and document daily operation and maintenance of the facility and must comply with all other conditions of 15A NCAC SG .0202. Once the facility is classified, the Permittee must submit a letter to the WPCSOCC which designates the operator in responsible charge within 30 days after the wastewater treatment facilities are 50 percent complete. 3_ Irrigation shall not be performed during inclement weather or when the ground is in a condition that will cause runoff. 4. Adequate measures shall be taken to prevent wastewater runoff from the spray field. 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. A suitable year round vegetative cover shall be maintained. Required maintenance shall include the timely harvest, and immediate off -site removal of the harvested product. 7_ The application rate shall not exceed a cumulative loading of 11.40 inches over any 12-month period, at an instantaneous application rate of up to 0.22 inches per hour. At no time, shall the instantaneous applicatic rate (inches applied per hour-IPH) result in surface run-off conditions. Nor shall the instantaneou i application rate (IPH) result in ponded wastewater conditions. Prior to applying spray irrigation effluent to the permitted spray application sites (see Condition VI. 4.) that have previously received, or are intended to receive animal waste (e.g., poultry litter, hog lagoon effluent, manure solids, etc.) in the future, the Permittee shall obtain information pertaining to the volume and analysis of the applied waste. The Permittee shall be responsible for verifying the volume of spray irrigation effluent that may be land applied to the site such that the plant available nitrogen (PAN) loading rate for the specified crop (see Condition H. 9.) is not exceeded by ALL sources of PAN applied. Should the maximum PAN loading rate be met, then no additional spray irrigation effluent shall be applied to the site for the remainder of the cropping season_ 9. The following North Carolina Division of Agriculture (NCDA) recommended application rates of Plant Available Nitrogen (PAN) shall not be exceeded for any of the given specified crops, below. At any time, the Permittee may submit a Waste Utilization Plan (which includes PAN application to Site ]A and Site 1B) to the Division for acknowledgement and approval, in order to adjust PAN to reflect site -specific conditions. Crop PAN 1pnunds NI ac Lely ear Crop PAN(Pounds N/acre/ ear Bermuda Grass (Hay) 220 Milo 100 Small Grain (Wheat, Barley, Oats) 100 Corn (Grain) 160 Corn (Silage) 200 Sorghum, Sudex (Silage) 220 Cotton 70 Soybeans 200 Fescue (Hay) 250 Timothy, Orchard, & Rye Grass (Hay) 200 If the either approved Site 1A or Site 1B are in a Bermuda Grass (Hay) -Small Grain overseed rotation, then the small grain crop shall receive an application of PAN at a rate of no greater than 50 pounds PAN/acre/year. This practice will be allowed as long as the small grain is to be harvested. If the small grain is to be planted for erosion control only, and is to be tilled into the soil, then no wastewater effluent shall be applied to the small grain crop, since additional PAN applied to this crop, will not be removed (harvested) from the soil. 10. No type of wastewater, other than that from the Dail.Brothers Livestock Trailer Washout Facility, shall be sprayed onto the irrigation area. H. Domestic wastewater sources (for example: Toilet flush water, or human septage pump -out, etc.) are prohibited from entering the Livestock Trailer Washout FaciIity's treatment lagoon; and prohibited from being applied via spray irrigation effluent to the designated irrigation field. Under no circumstances shall the Permittee allow domestic wastewater to enter the Livestock Trailer Washout Facility's treatment or spray irrigation system. 12. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while normal maintenance is being performed. Extreme care should be taken by Permittee to avoid causing excessive soil compaction conditions during routine maintenance of the spray application area. 13. Public access to the land application sites shall be controlled during active site use. Such controls may include the posting of signs showing the activities being conducted at each site. 14. Freeboard in the storage lagoon shall not be less than two feet at any time. 15. A waste -level gauge, to monitor waste levels in the storage pond, shall be installed within 60 days of issuance of this permit. This gauge shall have readily visible permanent markings indicating the maximum liquid level at the top of the temporary liquid storage volume, minimum liquid level at the bottom of the'temporary liquid storage volume, and top of the dam elevations. Caution must be taken not to damage the integrity of the liner when installing the gauge. 16. Only those cleaning agents and soaps that are EPA approved, will not harm the cover crop, and will not contravene the groundwater standards listed in 15A NCAC 2L may be utilized in the Dail Brothers Livestock Trailer Washout Facility facility. Instruction labels are to be followed when using cleaning agents and soaps. 17. Engine and engine parts shall not be washed or rinsed in the wastewater system. Oil drained from engine crankcases, antifreeze or degreasing solvent wastes SHALL NOT be discharged into the disposal system. 18. Results from the soils analysis required in Permit Condition RI. 4., shall be utilized by the Permittee, to determine the appropriate amount of lime and/or gypsum to be incorporated into the spray irrigation field to neutralize the potential build-up of salts within the primary soil horizon (i.e., effective rooting depth of the crop grown, or soil horizon O/A (up to 12 inches), whichever is least in depth) of the designated irrigation field. The salt build-up hazard is due to the continuous addition of trailer cleaning agents and disinfectants to the spray irrigation effluent. If the accumulation of salts results in the soil's inability to properly assimilate spray irrigation effluent (i.e. soil infiltration rate is less than 0.22 inches per hour, refer to Condition H. 7.), then the Permittee must provide an alternative disposal site, subject to Division approval, prior to further spray irrigation activities_ III. MONITORING AND REPORTING REQUIREMENTS Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed necessary by the Division to insure surface and ground water protection will be established and an acceptable sampling reporting schedule shall be followed. 2. Adequate records shall be maintained by the Permittee tracking the amount of wastewater disposed. These records shall include, but are not necessarily limited to, the following information: a. Date of irrigation; b. Volume of wastewater irrigated; c. Field irrigated; d. Length of time field is irrigated; e. Continuous weekly, monthly, and year-to-date hydraulic (inches/acre) loadings for each field; f. Continuous weekly, monthly, and year-to-date PAN (pounds/acre) loadings for each field; g. Nitrogen balance for each field after an application event; h. Weather conditions; is Cover crop; and j. Maintenance of cover crops. The effluent from the subject facilities shall be monitored by the Permittee at the point prior to irrigation EVERY MARCH, JULY, and NOVEMBER, for the following parameters: Fecal Coliform pH Sodium Magnesium Calcium Sodium Adsorption Ratio (by calculation) NCDA-CS (Agronomic Division) Waste analysis Report form' Fecal Coliform shall be required for the purpose of monitoring for any domestic septage contribution to the effluent stream (strictly prohibited in Condition 11. 10., and IL 11.), due to Permittee's history of connecting a toilet to the storage lagoon. If the Permittee provides documentation to the Division for acknowledgement and approval, substantiating that the toilet referred to in Condition 1I. 11., has been fully decommissioned, AND a notarized letter providing written assurance that no further storage pond -connected toilet facilities will be installed in the future, this parameter shall be removed. 2 Analysis report shall be used in the monitoring and proper management of the cover crops grown on the spray irrigation field. The analysis report shall also be used as an indicator to prevent any permanent damage to the soil infiltration rate of the designated spray irrigation field. 4. An ANNUAL representative soils analysis (Standard Soil Fertility Analysis) shall be conducted during the months of April 15t' to September 15''' (after initial sampling date is established, future annual sampling, thereafter, shall occur on or near the date of the initial sampling (+/- up to seven days)) on each permitted spray field area, and the results shall be maintained on file by the Permittee for a minimum of five year: The soil sample depth used, shall be at either the effective rooting depth of the crop grown, or within soi horizon O/A (up to 12 inches), whichever is least in depth. The Standard Soil Fertility Analysis shall include, but is not necessarily limited to, the following parameters: Acidity Manganese Potassium Calcium Percent Humic Matter Sodium Copper pH Zinc Magnesium Exchangeable Sodium Percentage' Phosphorus Cation Exchange Capacity Base Saturation (by calculation) 'Due to the possibility of a presence of high salts in the spray irrigation effluent, the exchangeable sodium percentage (ESP) shall be monitored on the designated spray irrigation site by using the results from the annual soil analysis. ESP is calculated as follows. ESP = (Na (rnilliequivalents)/Cation Exchange Capacity (CEC)) x 100. If the ESP of the designated spray irrigation site results in an ESP of greater than 10 percent, consult the agronomic advice of the local Extension Office, the Department of Agriculture, the Natural Resource Conservation Service, Certified Agronomist, or a North Carolina Licensed Soil Scientist, prior to the further spray irrigation of effluent on the irrigation site of concern. Any of the above parties may review the ESP results, in light of the particular site conditions and make recommendations. The Permittee shall implement these recommendations in the management of the given spray irrigation site. Three copies of all operation and disposal records (as specified in Condition 111. 2.) on Form NDAR-I and three copies of all effluent monitoring data (as specified in Conditions 111. 3.) on Form NDMR-1 shall be submitted on or before the last day of the APRIL, AUGUST, and DECEMBER. Three copies of the representative soils analysis (as specified in Condition 111. 4.) shall be submitted ANNUALLY on or before March I' of the year following the initial spray irrigation event. All information shall be submitted 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 6. Noncompliance Notification: The Permittee shall report by telephone to the Wilmington Regional Office, telephone number (910) 395- 3900, 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.
