WESLEY BROWN, PUBLIC WORKS DIRECTOR TOWN of STAR POST OFFICE Box 97 STAR, NORTH CAROLINA 27356 Subject: Permit No. WQ0003945 Correction/Amendment Town of Star Town of Star Residuals Land Application Program Land Application of Residual Solids (503) Montgomery County Dear Mr. Brown: In accordance with a request made by the Town of Star to the Groundwater Section with the Division of Water Quality's (Division) Fayetteville Regional Office, we are forwarding herewith a corrected/amended Permit No. WQ0003945, issued on October 15, 2001, for the subject residuals land application program. The following corrections/amendments have been made to the permit: 1. The October 15, 2001 issuance of this permit originally required a significant change to the groundwater monitoring program as previously permitted. Specifically, four existing groundwater monitoring wells were to be abandoned, and three new groundwater monitoring wells were to be constructed and monitored. At the Pernuttee's request, a representative of the Groundwater Section with the Division's Fayetteville Regional Office visited the affected land application sites and used Global Positioning System (GPS) technology to establish the exact locations of four of the existing groundwater monitoring wells. As a result, it has been determined that only two of the groundwater monitoring wells should be abandoned, and the local groundwater resources may now be monitored by sampling four existing groundwater monitoring wells. This means that no new groundwater monitoring wells need to be constructed and monitored by the Perrnittee. Section IV. (i.e. "Groundwater Requirements") has, therefore, been changed significantly in this corrected/amended permit to reflect these modifications to the overall groundwater monitoring program. Please note that a more accurate map of the land application sites (i.e., one that accurately depicts the locations of all existing groundwater monitoring wells) would have prevented this delay and confusion associated with the design of an appropriate groundwater monitoring program. 2. Because Section 1V. (i.e., "Groundwater Requirements") changed so significantly, the Division has taken this opportunity to reissue this permit in the format currently being used for all residuals land application programs. This format was developed to facilitate new application review procedures that have been put into place by the Division. Although no substantive changes have been made to the conditions contained within this permit, the Permittee should take the time to review this document to ensure complete familiarity and understanding of the format and the condition language.

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 Iisted 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 (ESP) 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. 4 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 11. 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 Iand applied to the site. 12. A suitable vegetative cover, as listed in Condition 11. 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 crops: PAN - PAN Crop (pounds per Crop (pounds per acre per year) acre per year) 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 ISO (Grain) (Pasture) Corn 200 Sorghum or Sudex 220 (Silage) —(Silage) 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 land 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 applications 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. C7 IIL MONITORING AND REPORTING REQUIREMENTS 1. 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 listed 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.

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 Perrnittee 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.

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 residuaIs, 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. I. 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 IlI. 2., Condition III. 3., and Condition III. 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. y 6. 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.

This report shall outline the actions taken or proposed to be taken to ensure that the problem does not recur. IV. GROUNDWATER REQUIREMENTS 1. Well Construction/Abandonment Reouiremenis: By July 1, 2002, the groundwater monitoring wells, MW-1 and MW-6, shall be permanently abandoned. The wells shall be abandoned either by a North Carolina - certified well contractor, the property owner, or the property lessee according to North Carolina General Statute §87-94.4(b)(2). If the well abandonment is not performed by a North Carolina -certified well contractor, the property owner or lessee shall physically perform the actual well abandonment activities, and the well shall be abandoned according to 15A NCAC 2C .0113 (i.e., "Abandonment of Wells") and any applicable local rules. Within 30 calendar days of the well abandonment activities, a "Well Abandonment Record" (i.e., GW-30 Form) shall be completed for the abandoned well and mailed to the address listed in Condition IV. 3b. 10 K 91 SamplingRequire_ments: a. Groundwater monitoring wells MW-2, MW-3, MW-4, and MW-5 shall be sampled every February and August for the parameters listed below: Nitrate -Nitrogen Total Organic Carbon pH Volatile Organic Compounds (In August Only) Total Ammonia Nitrogen Water Level Total Dissolved Solids Water levels in the groundwater monitoring wells shall be measured prior to sampling the groundwater for the remaining parameters. The depth to water in each well shall be measured from the surveyed point on the top of the casing, which shall be surveyed relative to a common datum. b. If total organic carbon (TOC) concentrations greater than 10 milligrams per Iiter are detected in any downgradient groundwater monitoring well, additional sampling and analysis shall be conducted to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background well exceeds 10 milligrams per liter, this concentration shall be taken to represent the naturally -occurring TOC concentration. Any exceedances of this naturally -occurring TOC concentration in downgradient wells shall be subject to the additional sampling and analysis as described in this permit. c. Volatile Organic Compounds (VOCs) shall be analyzed using one of the following methods: - (A) Standard Method 6230D (PQL at 0.5 µg/L or less), (B) Standard Method 6210 (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), or (E) Another method with prior approval by the Groundwater Section Chief. Any method used shall, at a minimum, include all of the constituents listed in Table VIII of Standard Method 6230D. Any method used shall provide a PQL of 0.5 µg/L or less, which shall be supported by laboratory proficiency studies as required by the Division's Laboratory Certification Unit. Any constituents detected above the MDL, but below the PQL at 0.5 µ g/L, shall be qualified (estimated) and reported. d. Any laboratory selected to analyze parameters shall be Division -certified for those parameters required. Reporting/Documentation Requirements: a. The results of the sampling and analysis shall be received on the most -recent version of "Groundwater Quality Monitoring: Compliance Report Form" (i.e., GW-59 Form) with copies of the laboratory analyses attached by the Division's Groundwater Section on or before the last working day of the month following the sampling month. 11 b. AlI reports (e.g., GW-30 Form, GW-59 Form, etc.) shall be mailed to the following address: NCDENR-DWQ Groundwater Section Permits and Compliance Unit 1636 Mail Service Center Raleigh, NC 27699-1636 Updated blank reporting and other forms may be downloaded from the web site for the Division's Groundwater Section at http://gw.chnr.state .nc. us/ or requested from the address listed above. 4. 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. Applicable Boundary Requirements: a. The COMPLIANCE BOUNDARY for residuals land application programs is specified by regulations in 1SA 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.
