An acceptable pH shall be maintained in the soil, residuals, and lime mixture, greater than 6.0, on all land application sites onto which residuals are land applied to ensure optimum yield for the crops specified in Condition 11. 13. The agronomist shall provide information on the pH best suited for the specified crop and the soil type. 10. Should any of the residuals generated by the residuals source -generating facilities listed in the most recently -certified Attachment A of this permit contain a high salt content (i.e., high sodium adsorption ratio (SAR) of five or higher), the exchangeable sodium percentage (ESA) or other method as approved by the Division, using the results from the annual soils analysis as required by this permit, shall be monitored on all of the land application sites. The local Cooperative Extension Office, the Department of Agriculture and Consumer Services, the Natural Resource Conservation Service, a North Carolina -licensed Soil Scientist, or other agronomist shall review the results and make recommendations regarding soil amendments (e.g., gypsum, etc.) or other ameliorative mechanism for maintaining the integrity of the site in terms of suitability for land application of residuals and maintaining conditions conducive to crop growth, The Permittee shall implement such recommendations accordingly and shall maintain written records of each monitoring event that includes details of the sites covered and rate of soil amendment application. 11 11. Prior to land applying residuals to any land application site that has previously received or is intended to receive animal waste (e.g., poultry litter, etc.) or other source of nutrients (e.g., fertilizer, etc.) in the future, the Permittee shall obtain information pertaining to the volume and analysis of the applied waste/nutrients from the landowner and/or lessee/operator of the site. The Permittee shall be responsible for verifying the volume of residuals that may be land applied to the site such that the plant available nitrogen (PAN) loading rate for the specified crop (i.e., see Condition H. 13.) shall not be exceeded by all of the sources of PAN applied. Should the maximum PAN loading rate be met or exceeded, then no additional residuals shall be land applied to the site. 12. A suitable vegetative cover, as listed in Condition II. 13., shall be maintained on land application sites onto which residuals are land applied in accordance with the crop management plan outlined by the local Cooperative Extension Office, the Department of Agriculture and Consumer Services, the Natural Resource Conservation Service, or other agronomist and as approved by the Division. 13. Residuals and other sources of PAN shall be land applied to all land application sites at agronomic rates in accordance with the crop management plan outlined by the local Cooperative Extension Office, the North Carolina Department of Agriculture and Consumer Services, the Natural Resource Conservation Service, or other agronomist. Under no circumstances shall the following PAN loading rates land applied to any site exceed the following for the specified crows: PAN PAN Crop (pounds per Crop (pounds per acre per ear acre er ear) Alfalfa 200 Forest 75 (Hardwood or Softwood) Bermuda Grass 220 Milo 100 (Hay or Pasture) Blue Grass 120 Small Grain 100 (Wheat, Barley, or Oats Corn 160 Sorghum or Sudex 180 (Grain) (Pasture) Corn Sorghum or Sudex (Silage) 200 (Silage) 220 Cotton 70 Soybeans 200 Fescue 250 Timothy, Orchard, or 200 Rye Grasses The Permittee shall apply for and receive a modification of this permit before land applying residuals on any land application site that is to be established in a crop other than those listed above. A maximum PAN loading rate for the desired crop shall be approved with the permit modification. If the land application sites are to be overseeded (e.g., bermuda grass in the summer and rye grass in the winter with BOTH crops to receive residuals), then the second crop shall receive an application of PAN at a rate of no greater than 50 pounds per acre per year. This practice shall be allowed as long as the second crop is to be harvested. If the second crop is to be planted for erosion control only and is to be tilled into the soil, then no residuals shall be land applied to these sites because the PAN will essentially be returned to the soil. 5 Residuals shall not be land applied at rates greater than agronomic rates, unless authorized by the Division. 14. Animals shall not be grazed on any land application site for 30 days after any residuals land application event. Sites that are to be used for grazing shall have fencing that will be used to prevent access after each event. 15. Food crops, feed crops, and fiber crops that do not come in contact with the residuals shall not be harvested for 30 days after any residuals land application event. 16. Food crops with harvested parts that touch the residual/soil mixture and are totally above the land surface (e.g., tobacco, melons, cucumbers, squash, etc.) shall not be harvested for 14 months after any residuals land application event. 17. Food crops with harvested parts below the surface of the land (i.e., root crops such as potatoes, carrots, radishes, etc.) shall not be harvested for 20 months after any residuals land application event when the residuals remain on the Iand surface for four months or longer prior to incorporation into the soil. 18. Food crops with harvested parts below the surface of the land shall not be harvested for 38 months after any residuals land application event when the residuals remain on the land surface for less than four months prior to incorporation into the soil. 19. Turf shall not be harvested for one year after any residuals land application event. 20. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying residuals from the land application sites onto adjacent properties or into any surface waters. 21. Adequate procedures shall be provided to prevent surface runoff from carrying any land applied or stored residuals into any surface waters. 22. Surface -applied residuals shall be plowed or disced within 24 hours after land application on land application sites with no cover crop established. 23. For land application sites that are prone to flooding or within the 100-year flood elevation, residuals shall be land applied only during periods of dry weather. The residuals shall be incorporated into the soil within 24 hours after land application. 24. Residuals shall not be land applied during inclement weather or until 24 hours following a rainfall event of 0.5-inch or greater in 24 hours. Any emergency residuals land application measures shall first be approved in writing by the Division. 25. Residuals shall not be land applied to any land application site that is flooded, frozen, or snow-covered. 26. Appropriate measures shall be taken to control public access to the land application sites during active site use and for the 12-month period following the last residuals land application event. Such - controls may include the posting of signs indicating the activities being conducted at each site. C1 M. MONITORING AND REPORTING REQUIREMENTS Any monitoring (i.e., including groundwater, surface water, residuals, soil, or plant tissue analyses) deemed necessary by the Division to ensure protection of the environment shall be established, and an acceptable sampling and reporting schedule shall be followed. 2. Residuals generated by each residuals source -generating facility Iisted in the most -recently - certified Attachment A of this permit shall be analyzed to demonstrate that they are non- hazardous under the Resource Conservation and Recovery Act (RCRA). A corrosivity, ignitability, and reactivity analysis as well as a Toxicity Characteristics Leaching Procedure (TCLP) analysis shall be conducted on residuals generated by each residuals source - generating facility listed in the most recently -certified Attachment A of this permit. The analyses shall be performed at the frequency specified in the most recently -certified Attachment A of this permit, and the results shall be maintained on file by the Permittee for a minimum of five years. If residuals generated by a particular residuals source -generating facility are land applied at a frequency less than that which is specified in the most recently - certified Attachment A of this permit, the analyses shall be required for each residuals land application event. Only residuals that are generated by the residuals source -generating facilities that are identified as being exempt from this condition in the most recently -certified Attachment A of this permit shall not be required to comply with this monitoring requirement. The TCLP analysis shall include the following parameters (i.e., note the regulatory level in milligrams per liter in parentheses): Arsenic (5.0) 1,4-Dichlorobenzene (7.5) Nitrobenzene (2.0) Barium (100.0) 1,2-Dichloroethane (0.5) Pentachlorophenol (100.0) Benzene (0.5) 1, 1 -Dichloroethylene (0.7) Pyridine (5.0) Cadmium (1.0) 2,4-Dinitrotoluene (0.13) Selenium (1.0) Carbon tetrachloride (0.5) Endrin (0.02) Silver (5.0) Chlordane (0.03) Hexachlorobenzene (0.13) Tetrachloroethylene (0.7) Chlorobenzene (100.0) Heptachlor (and its hydroxide) (0.008) Toxaphene (0.5) Chloroform (6.0) Hexachloro-1,3-butadiene (0.5) Trichloroethylcne (0.5) Chromium (5.0) Hexachloroethane (3.0) 2,4,5-Trichlorophenol (400.0) m-Cresol (200.0) Lead (5.0) 2,4,6-Trichlorophenol (2.0) o-Cresol (200.0) Lindane (0.4) 2,4,5-TP (Silvex) (1.0) p-Cresol (200.0) Mercury (0.2) Vinyl chloride (02) Cresol (200.0) Methoxychlor (10.0) 2,4-D (10.0) Methyl ethyl ketone (200.0) After the residuals have been monitored as specified above for two years at the frequency specified in the most recently -certified Attachment A of this permit, the Permittee may submit a request to the Division for a permit modification to request a reduction of this monitoring requirement. In no case, however, shall the frequency of monitoring be less than once per permit cycle. 7 3. An analysis shall be conducted on residuals generated by each residuals source -generating facility listed in the most recently -certified Attachment A of this permit. The analysis shall be performed at the frequency specified in the most recently -certified Attachment A of this permit, and the results shall be maintained on file by the Permittee for a minimum of five years. If residuals generated by a particular residuals source -generating facility are land applied at a frequency less than that which is specified in the most recently -certified Attachment A of this permit, an analysis shall be required for each residuals land application event. The analysis shall include, but shall not necessarily be limited to, the following parameters: Aluminum Ammonia -Nitrogen Arsenic Cadmium Calcium Copper Lead Magnesium Mercury Molybdenum Nickel Nitrate -Nitrite Nitrogen Percent Total Solids pH Phosphorus Potassium Selenium Sodium Total Kjeldahl Nitrogen Zinc Plant Available Nitrogen (by calculation) After the residuals generated by a particular residuals source -generating facility have been monitored for two years at the frequency specified in the most recently -certified Attachment A of this permit, the Permittee may submit a request to the Division for a permit modification to reduce the frequency of this monitoring requirement. In no case, however, shall the frequency of this monitoring be less than once per year when a residuals land application event of residuals generated by the residuals source -generating facility occurs during that year. 4. Residuals generated by each residuals source -generating facility listed in the most recently - certified Attachment A of this permit shall be monitored for compliance with Condition I. 7. The monitoring shall be performed at the frequency specified in the most recently -certified Attachment A of this permit, and data to verify pathogen and vector attraction reduction of the residuals shall be maintained on file by the Permittee for a minimum of five years. The required data shall be specific to the stabilization process utilized, but also shall be sufficient to demonstrate clear compliance with the Class A pathogen reduction requirements in 40 CFR Part 503.32(a) or the Class B pathogen reduction requirements and site restrictions in 40 CFR Part 503.32(b) as well as one of vector attraction reduction requirements in 40 CFR Part 503.33. In addition, the Environmental Protection Agency (EPA) certification statements concerning compliance with pathogen reduction requirements, vector attraction reduction requirements, and management practices shall be completed quarterly by the proper authority or authorities, if more than one is involved (i.e., either the person who prepares the residuals, the person who derives the material, or the person who applies the residuals). Only residuals that are generated by the residuals source -generating facilities that are identified as being exempt from Condition 1. 7. in the most recently -certified Attachment A of this permit shall not be required to comply with this monitoring requirement. Laboratory analyses as required by Condition IIl. 2., Condition III. 3., and Condition 111. 4. shall be performed/gathered on the residuals as they are to be land applied. Furthermore, analytical determinations made pursuant to the monitoring and reporting requirements of this permit shall be made by a laboratory certified by the Division for the required parameter(s) under 15A NCAC 211.0800 or 15A NCAC 2H .1100. Proper records shall be maintained by the Permittee tracking all residuals land application events. These records shall include, but are not necessarily limited to, the following information: a. Source of residuals; b. Date of land application; c. Location of land application (i.e., site, field, or zone number); d. Method of land application; e. Weather conditions (i.e., sunny, cloudy, raining, etc.); f. Soil conditions (i.e., dry, wet, frozen, etc.); g. Type of crop or crops to be grown on field; h.

Any occurrence with the residuals land application program that results in the land application of significant amounts of residuals that are abnormal in quantity or characteristic. b. Any failure of the residuals land application program resulting in a release of material to receiving waters. c. Any time that self -monitoring information indicates that the residuals land application program has gone out of compliance with the conditions and limitations of this permit or the parameters on which the program system was designed. d. Any process unit failure, due to known or unknown reasons, that render the residuals land application program incapable of adequate residuals treatment. e. Any spillage or discharge from a vehicle or piping system transporting residuals to the application site. Persons reporting such occurrences by telephone shall also file a written report in letter form within five days following first knowledge of the occurrence. This report shall outline the actions taken or proposed to be taken to ensure that the problem does not recur. IV. GROUNDWATER REQUIREMENTS 1. Land Application Site Requirements: a. Each land application site identified with a GW-A in the most recently -certified Attachment B of this permit is dominated by soils with a mean seasonal high water table greater than three feet below the land surface. Residuals land application events may occur on these sites throughout the year. b. Each land application site identified with a GW-B in the most recently -certified Attachment B of this permit is dominated by soils with a mean seasonal high water table between one and three feet below the land surface. Residual land application events on these sites shall be prohibited from December through March, inclusive. No residuals shall be land applied to these sites when the vertical separation between the depth of residuals land application and the water table is less than three feet. The actual water table depth for seasonally -restricted soils shall be verified by soil borings within 24 hours prior to any residuals land application event that occurs from April through November, inclusive. The number of borings -advanced shall be sufficient to characterize water table conditions across the land application site adequately. Any open borings shall be properly filled with native soil, prior to the residuals land application event, to decrease the chance of any residuals contaminating the groundwater. 10 2. Applicable Boundary Requirements: a. The COMPLIANCE BOUNDARY for residuals land application programs is specified by regulations in 15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The Compliance Boundary for each land application site is established at either 250 feet from the residuals land application area or 50 feet within the property boundary, whichever is closest to the residuals land application area. An exceedance of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate remediation action according to 15A NCAC 2L .0106 (d)(2). b. The REVIEW BOUNDARY shall be established around each land application site midway between the Compliance Boundary and the perimeter of the residuals land application area. Any exceedance of Groundwater Quality Standards at the Review Boundary shall require action in accordance with 15A NCAC 2L A 106 (d)(2). Additional Requirements: a. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided. 4. Prior to disposal of residuals on Areas 9 and 10 on the attached map, two new monitor wells, MW-6 and MW-7, shall be installed to monitor groundwater quality. The wells shall be constructed such that the water Ievel in the well is never above or below the screened (open) portion of the well at any time during the year. The general location and name for each well is marked on Attachment A. Each monitoring well shall be Iocated at the review boundary, constructed in accordance with this permit, and approved by the Washington Regional Office. The measuring points (top of well casing) of Monitor Wells MW-6 and MW-7 shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. 6. New Monitor wells MW-6 and MW-7 shall be sampled initially after construction and before land application to the adjacent field, and thereafter every February, June, and October for the following parameters: Chloride Total Ammonia Fecal Coliforms Total Dissolved Solids Nitrate Nitrogen Water Levels PH Volatile Organic Compounds —(hi October only) Volatile Organic Compounds (VOC) by one of the following methods: (A) Standard Method 6230D, PQL at 0.5 pg/L or less (B) Standard Method 6210D, PQL at 0.5 µg/L or less (C) EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less (D) EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less (E) Another method with prior approval by the Groundwater Section Chief Any method used must meet the following qualifications: (1) A laboratory must be DWQ certified to run any method used. (2) The method used must, at a minimum, include all the constituents listed in Table V1II of Standard Method 6230D. 11 (3) The method used must provide a pql of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported. 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. If any volatile organic compounds are detected by the methods listed, then the Washington Regional Office Aquifer Protection. Supervisor, telephone number 252-946- 6481, 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 must be received on Form GW-59 (Groundwater Quality Monitoring: Compliance Report Form) by the Division of Water Quality, Information Processing Unit, 1617 Mail Service Center, Raleigh, N.C_ 27699-1617 on or before the last working day of the month following the sampling month. 7. Within sixty (60) days of permit issuance, monitor well MW-4, shall be temporarily abandoned by securing the wellhead to prevent access by hand. This restriction of access may be accomplished by using a padlock that would secure the well cap to the protective casing or by some other acceptable means to the Groundwater Section. The well shall be further secured by placing a compatible watertight cap or seal onto the riser pipe to prevent potential contamination from entering the well. 8. Monitor wells MW-1, MW-2, MW-3, MW-5 and, after installation, MW-6 and MW-7 shall be sampled every February, June, and October for the following parameters: Chloride Total Ammonia Fecal Coliforms Total Dissolved Solids Nitrate Nitrogen Water Levels pH Volatile Organic Compounds —(In October only) Volatile Organic Compounds (VOC) by one of the following methods: (A) Standard Method 6230D, PQL at 0.5 µg/L or less (B) Standard Method 6210D, PQL at 0.5 µg/L or less (C) EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less (D) EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less (E) Another method with prior approval by the Groundwater Section Chief Any method used must meet the following qualifications: 1. A laboratory must be DWQ certified to run any method used. 2. The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D. 12 3. The method used must provide a pql of 0.5 pLg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported. 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. If any volatile organic compounds are detected by the methods listed, then the Washington Regional Office Aquifer Protection Supervisor, telephone number 252-946-6481, 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 must be received on Form GW-59 (Groundwater Quality Monitoring: Compliance Report Form) by the Division of Water Quality, Information Processing Unit, 1617 Mail Service Center, Raleigh, N.C. 27699-1617 on or before the last working day of the month following the sampling month. 9. No land application of waste activities shall be undertaken when the seasonal high water table is less than three feet below land surface. 10. Residuals shall only be applied at agronomic rates, and on an application rotation schedule which is designed to achieve an equitable distribution (based on the accommodation capability of each site) of residuals among the established sites. The use of predictive calculations and/or numerical modeling may be necessary to determine appropriate allocations at specific sites that will not result in a contravention of Groundwater Standards at the review Boundary. 11. All wells that are constructed for purposes of groundwater monitoring shall be constructed in accordance with 15A NCAC 2C .0108 (Standards of Construction. for Wells Other than Water Supply) and any other state and local laws and regulations pertaining to well construction. 12. The Washington Regional Office, telephone number 252-946-6481, shall be notified at least forty-eight (48) hours prior to the construction of any monitoring well so that an inspection can be made of the monitoring well location. Such notification to the regional Aquifer Protection 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. 13. Within sixty (60) days of completion of all monitoring wells, the permittee shall submit two original copies of a scaled topographic map (scale no greater than 1 ":100') signed and sealed by a professional engineer or a state licensed land surveyor that indicates all of the following information: a. the location and identity of each monitoring well, b. the location of the waste disposal system, c. the location of all property boundaries, d. the latitude and longitude of the established horizontal control monument, e. the relative elevation of the top of the well casing (which shall be known as the "measuring point"), and 13 f. the depth of water below the measuring point at the time the measuring point is established. The survey shall be conducted using approved practices outlined in North Carolina General Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56. The surveyor shall establish a horizontal control monument on the property of the waste disposal system and determine the; latitude and longitude of this horizontal control monument to a horizontal positional accuracy of +/- 10 feet. All other features listed in a. through e. above shall be surveyed relative to this horizontal control monument. The positional accuracy of features listed in a. through e, above shall have a ratio of precision not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of the survey. Any features located by the radial method will be located from a minimum of two points. Horizontal control monument shall be installed in such a manner and made of such materials that the monument will not be destroyed due to activities that may take place on the property. The map shall also be surveyed using the North American Datum of 1983 coordinate system and shall indicate the datum on the map. All bearings or azimuths shall be based on either the true or NAD 83 grid meridian. If a Global Positioning System (GPS) is used to determine the latitude and longitude of the horizontal control monument, a GPS receiver that has the capability to perform differential GPS shall be used and all data collected by the GPS receiver will be differentially corrected. The maps and any supporting documentation shall be sent to the Division of Water Quality, Information Processing Unit, Mail Service Center 1617, Raleigh, N.C. 27699- 1617. 14. Within thirty (30) days of completion of all well construction activities, a certification must be received from a professional engineer certifying that the monitoring wells are located and constructed in accordance with the Well Construction Standards (15A NCAC 2C) and this permit. This certification should be submitted with copies of the Well Completion Form (GW-1) for each well. Mail this certification and the associated GW-1 forms to the Division of Water Quality, Information Processing Unit, Mail Service Center 1617, Raleigh, N.C. 27699-1617, 15. For the initial sampling of the two new wells as specified elsewhere in the permit, the permittee shall submit a copy of the GW-1 Form (Well Completion Form) with the Compliance Monitoring Form (GW-59) for that well. Compliance Monitoring Fortes that do not include copies of the GW-1 form will be returned to the permittee without being processed. Failure to submit these forms as required by this permit may result in the initiation of enforcement activities pursuant to NC General Statutes 143-215.6. 14 V. INSPECTIONS Prior to each residuals land application event, the Permittee or his designee shall inspect the residuals storage, transport, and application facilities to prevent malfunctions and deterioration, operator errors, and discharges that may cause or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
