This waste utilization plan uses nitrogen as the limiting nutrient.Waste should be analyzed before each application cycle.Annual soil tests are strongly encouraged so that all plant nutrients can be balanced for realistic yields of the crop to be grown. Several factors are important in the implementing your waste utilization plan in order to maximize the fertilizer value of the waste and to ensure that it is applied in an environmentally safe manner. 1. Always apply waste based on the needs of the crop to be grown and the nutrient content of the waste. Do not apply more nitrogen than the crop can utilize. 2. Soil types are important as they have different infiltration rates, leaching potentials, cation exchange capacities,and available water holding capacities. 3. Normally waste shall not be applied to land eroding at more than 5 tons per acre per year.Waste may be applied to land eroding at 5 or more tons per acre annually, but less than 10 tons per acre per year providing that adequate filter strips are established. 4. Do not apply waste on saturated soils,when it is raining, or when the surface is frozen. Either of these conditions may in runoff to the surface waters which is not allowed under DWQ regulations. 5. Wind conditions should also be considered to avoid drift and downwind odor problems. 6. To maximize the value of the nutrients for crops production and to reduce the potential for pollution,the waste should be applied to a growing crop or applied not more than 30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or disking will conserve nutrients and reduce odor problems. This plan is based on the waste application method shown above. If you choose to change methods in the future,you need to revise this plan. Nutrient levels for different applications methods are not the same. The estimated acres needed to apply the animal waste is based on typical nutrient content for this type of facility.Acreage requirements should be based on the waste analysis report from your waste management facility. In some cases you may want to have plant analysis made,which it Bull&Buddy Farms Page 2 could allow additional waste to be applied. Provisions shall be made for the area receiving waste to be flexible so as to accommodate changing waste analysis content and the production.crop type p p Lime must be applied to maintain H in the op timum rang a forspecific crop waste utilization plan,if carried out, meets the requirements for compliance with 15A NCAC 2H.0217 adopted by the Environmental Management Commission.

I I i i Bull&Buddy Farms Page 3 i, The applicator is cautioned that P and K may be over applied while meeting the N requirements. In the future, regulations may require farmers in some parts of North Carolina to have a nutrient management plan that i addresses all nutrients.This plan only addresses nitrogen. i In interplanted fields(i.e.small grain,etc.interseeded in bermudagrass),forage must be removed through ! ha and or silage.Where grazing,plants should be razed when the reach a height of six to nine grazing, Y / g g g,P g Y g inches.Cattle should be removed when plants are grazed to a height of four inches. In fields where small grain etc.is to be removed for hay or silage,care should be exercised not to let small grain to reach maturity, especially late in the season( i.e.April or May)Shading may result if small grain gets too high and this will definitely interfere with the stand of bermudagrass.This loss of stand will result in reduced yields and less nitrogen being utilized. Rather than cutting small grain for hay or silage just before heading as is the normal situation,you are encouraged to cut the small grain earlier.You may want to consider harvesting hay or silage two to three times during the season,depending on the time small grain is planted in the fall. The ideal time to interplant small grain,etc.is late September or early October. Drilling is recommended over broadcasting. Bermudagrass should be grazed or mowed to a height of about two inches before drilling for best results. I i Caution must be exercised in grazing or haying summer annuals under stressed conditions. Nitrate poisoning may occur in livestock.Sampling forage or hay for nitrate levels is recommended. I Acres shown in the tables are considered to be the usable acres excluding required buffers,filters strips along ditches,odd areas unable to be irrigated,and perimeter areas not receiving full application rates due to equipment limitations.Actual total acres in the field listed may,and most likely will be,more than the acres shown in the tables. See attached map showing the fields to be used for the utilization of animal waste. I SLUDGE APPLICATION: The waste utilization plan must contain provisions for periodic land application of sludge at agronomic rates. The sludge will be nutrient rich and will require precautionary measures to prevent over application of nutrients or other elements.Your production facility will produce approximately 711 lbs.of plant availabl� nitrogen per year in the sludge. If you remove sludge every 5 years you will have approximately 3555 lbs.of PAN to utilize.Assuming you apply this PAN to hybrid bermudagrass hayland at the rate of 300 lbs/acre you will need 1 12 acres of land.If you apply the sludge to corn at the rate of 125 lbs.of nitrogen per acre you will need ! 28 acres of land.Please be aware that these are only estimates of the PAN and the land needed.Actual requirements could vary by 25%depending on the sludge waste analysis,soil types,realistic yields,and application methods. APPLICATION OF WASTE BY IRRIGATION The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation such that runoff or ponding occurs.This rate is limited by initial soil moisture content,soil structure,soil texture,water droplet size,and organic solids.The application amount should not exceed the available water holding capacity I I I I i Bull&Buddy Farms Page 4 i of the soil at the time of irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of the crop i i If surface irrigation is the method of land application for this plan,it is the responsibility of the producer and irrigation designer to ensure that an irrigation system is installed to properly irrigate the acres shown in tables. Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid. i The following table is provided as a guide for establishing application rates and amounts.

In many situations the application amount shown cannot be applied because of the nitrogen limitations.The maximum application amount shown can be applied under optimum soil conditions. i Your facility is designed for 180 days of temporary storage and the temporary storage must be removed on the average of once every 6 months. In no instances should the volume of the waste be stored in your structure be within the 25 year 24 hour storm storage or one foot of freeboard except in the event of the 25 year 24 hour storm. i It is the responsibility of the producer and the waste applicator to ensure that the spreader equipment is operated properly to apply the correct rates shown in the tables. Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid. Call your technical specialist after you have receive the waste analysis report for assistance in determining the amount of waste per acre and the proper application rate prior to applying the waste. NARRATIVE OF OPERATION i i I 1 �I i i i I I Bull&Buddy Farms Page 6 WASTE UTILIZATION PLAN REQUIRED SPECIFICATIONS i 1. Animal waste shall not reach surface waters of the state by runoff,drift, manmade conveyances,direct application,or direct discharge during operation or land application. Any discharge of waste which reaches surface water is prohibited. I 2. There must be documentation in the design folder that the producer either owns or has an agreement for use of adequate land on which to properly apply waste. If the producer does not own adequate land to properly dispose of waste, he/she shall provide a copy of an agreement with a landowner who is within a reasonable proximity, allowing him/her the use of the land for waste application. It is the responsibility of the owner of the facility to secure an update of the Waste Utilization Plan when there is a change in the operation, increase in the number of animals, method of utilization, or available land. 3. Animal waste shall be applied to meet, but not exceed,the nitrogen needs for realistic crop yields based on soil type,available moisture,historical data,climatic conditions,and level of management, unless there are regulations that restrict the rate of application for other nutrients. 4. Animal waste shall be applied to land eroding less than 5 tons per acre per year.Waste may be applied to land that is eroding at 5 or more tons,but less than 10 tons per acre per year providing grass filter strips are installed where runoff leaves the field. (See FOTG standard 393-Filter Strip). 5. Odors can be reduced by injecting the waste or disking after waste application.Waste should not be applied when there is danger of drift from the irrigation field. 6. When animal waste is to be applied on acres subject to flooding,it will be soil incorporated on conventionally tilled cropland.When applied to conservation tilled crops or grassland, the waste may be broadcast provided the application does not occur during a season prone to flooding. (See"Weather and Climate in North Carolina"for guidance.) 7. Liquid waste shall be applied at rates not to exceed the soil infiltration rate that runoff does not occur offsite or to the surface waters and in a method which does not cause drift from the site during application. No ponding should occur in order to control odor or flies. 8. Animal waste shall not be applied to saturated soils,during rainfall events,or when the surface is frozen. 9. Animal waste shall be applied on actively growing crops in such a manner that the crop is not covered with waste to a depth that would inhibit growth.The potential for salt damage from animal waste should also be considered. 10. Waste nutrients shall not be applied in fall or winter for spring planted crops on soils with a high potential for leaching.Waste nutrient loading rates on these soils should be held to a minimum and a suitable winter cover crop planted to take up released nutrients.Waste shall not be applied more than 30 days prior to planting of the crop or forages breaking j dormancy. 11. Any new swine facility sited on or after October 1, 1995 shall comply with the following: The outer perimeter of the land area onto which waste is applied from a lagoon that is a component of a swine farm shall be at least 50 feet from any residential property boundary and from any perennial stream or river(other than an irrigation ditch or canal.Animal waste other than swine waste from facilities sited on or after October 1, 1995),shall not be applied closer than 25 feet to perennial waters.(See Standard 393-Filter Strips).

The Waste Utilization Plan for this farm is developed by Prestage Farms technical specialist. Waste is utilized on this farm by a cropping system comprised of Hybrid Bermuda Grass Hay overseeded with small grain. This plan includes new solid set irrigation in two existing sprayfield areas, and additional newly cleared area adjacent to one existing field. Table 1: Waste Utilization Area Properties Tract Field Soil Type Avail. Acres 71850 1,2,3 WoA 6.8 71850 N6 FoA 2.8 71850 4 FoA 1.83 Land Application System A solid set permanent irrigation system is specified for application of wastewater on this site. All sprinklers will be single nozzle Senninger 7025RD-1-1"M with all full circle spray patterns. The wetted diameter of the specified sprinkler is approximately 150 feet and the flowrate is 21.8 gpm at an operating pressure at the sprinkler of 65 pounds per square inch (psi). Based on field testing by NCSU, sprinklers are estimated to deliver approximately 90% of manufacturers stated spray diameter, so design is based on 135 feet. Using a common spacing of 60% of the wetted diameter requires a spacing of approximately 81 feet. Spacing on all sprinklers is 80 feet between sprinklers along each lateral and between each lateral. This spacing should provide a coefficient of uniformity of approximately 78%. Based on actual operation of existing equipment, the pump system will deliver approximately 230 gpm at 65 psi sprinkler pressure. The zoned system is arranged to spray 10-11 sprinklers in Zones 1-4, and 6 sprinklers in Zone 5. The operator must adjust flow utilizing inline valves to allow for proper flow based on number of sprinklers in each zone to prevent application beyond field borders. Currently 4" PVC pipe is buried underground as supply line to the existing system. This supply line system was previously installed to support a big gun solid set system, and the new system should be tied into this main line. The laterals shall be constructed of 2, 3, and 4" class 160 PVC pipe, size based on number of sprinklers in a lateral (See "PIPE INSTALLATION"). All fittings shall be constructed of Schedule 80 PVC and solvent soldered. Each zone shall have a gate valve as a shutoff and control mechanism. All sprinkler risers are to be approximately 1.5 feet in height and to be constructed of 2" Schedule 80 PVC pipe. Risers shall be installed according to the specifications shown on the riser installation detail of Appendix B of this document. Thrust blocks shall be placed around all entry points, tees, ells, valves, and ends of laterals. At startup, the operator should always make certain that the water has an outlet to prevent damage to the pump and supply lines. A 4"butterfly valve shall be placed on the discharge side of the flex assembly to allow the pumping unit to be disconnected without draining the supply line. Wastewater Application Specifications This solid set irrigation system is designed to apply wastewater to the bermuda grass hay and small grain-cropping regime. The soils for this acreage have been classified as Foreston and Woodington loamy sand. The following table summarizes the characteristics of the given soil types for this farm: Table 2: Site Soil Characteristics Field Soil Type Slope Cropping Precip. Max. No. Regime Rate App. Depth I Foreston 0-3% Bermuda Grass/ .50 .95 Small Grain 2 Woodington 0-3 % Bermuda Grass/ .40 1.3 Small Grain The MRCS allows up to a 0.95" application for Foreston class soil and a 1.3" application for an Woodington soil on a cover crop. As a precaution to ponding and runoff, the depth of application shall be limited to a maximum of 0.50" for both soils. The design application rate is shown in Table 3. This design application rate is based on the operating parameters of the irrigation system and the characteristics of the soil to prevent excessive ponding and runoff. However, good management practices in conjunction with the design application rate are the only ways to prevent ponding and runoff. Examples of good management practices are not spraying on frozen or saturated soil, not spraying on days when wind speeds exceed 5 miles per hour, etc. Since the lagoon is designed for 180 days of temporary storage, it is important that pumping occur regularly, with the last application on bermuda grass prior to frosting and the first application as early in the spring as possible. Although the operator is encouraged to irrigate as often as conditions permit, another application of wastewater must not be applied until the previous application has been utilized through evapotranspiration. If there are no rainfall events after the last application, the required time until a subsequent application may be made is usually 3 to 5 days. This time period is an estimate, however, and will vary with climate and local weather conditions. z During the winter months, when temperatures are likely to fall below freezing, the risers need to be drained to prevent damage from expansive freezing. The recommended depth to bury all supply lines and laterals is a minimum of 30 inches. Water should not freeze at this depth in the location of this irrigation system. To prevent damage, all pipes above the 30 inch bury depth should be drained. Likewise, the pump, suction line, and discharge line should be drained when freezing temperatures are likely to occur. System Maintenance In order that the system may perform efficiently and correctly, all components must be maintained and cared for. Sprinklers and air relief valves should be checked periodically to ensure that they are operating properly. Pressure gauges should be checked regularly. Although it is not necessary that the pump be kept under shelter, it is highly recommended that it be protected from the elements as much as possible. Any broken or damaged risers should be replaced or repaired as soon as possible. Sprinklers should be checked and kept free of debris. It is recommended that risers be kept clearly visible and marked to prevent breakage. It is a good practice to perform a routine inspection of all equipment each time before operating the irrigation system. If a problem is found during operation, such as a leak, immediately shut the system down and make the necessary repairs. If a leak or problem causes runoff of wastewater, the owner is required to follow the emergency action plan designed for the facility. Solid Set Irrigation Sprinkler Settings and Wettable Acres This system is designed to utilize Senninger 7025 impact sprinklers equipped with #20 (5/16") nozzles. These sprinklers are of single nozzle design with a 25' trajectory. This system design includes 49 full circle spray patterns. Table 3 outlines the parameters for each spray zone. The precipitation rate for each spray pattern was calculated and is shown in Table 3. Limiting the application depth to 0.33" should allow Exum soils to handle the design PR without ponding or runoff. Operator should closely monitor half circle sprays and manage to prevent runoff.

This describes how the irrigation system is designed to operate. Although this design specifies how the wastewater should be applied, the total amount of wastewater applied must not exceed the nutrient requirements of the cropping system as specified in the Nutrient Management Plan for this facility. Each application of wastewater should not exceed the application rate specified above and no more than total precipitation rate for each soil type listed in Table 2 above.

Accurate record keeping is a critical component of properly managing this irrigation system. Operating times, nutrient content of the wastewater, and operational pressures should be recorded to maintain accurate application rates. The North Carolina Certification Training for Operators of Animal Waste Systems Manual contains record keeping forms suited to this purpose. This information is also useful in determining maintenance required and needed adjustments to keep the irrigation system operating as specified in this design. Irrigation equipment should be calibrated annually and maintained in good working order. Pipe Installation All pipes are to be class 160 PVC plastic. Underground pipes shall have a minimum cover of 30 inches to prevent damage to pipe by equipment traffic and livestock. Backfill over pipes is to be compacted when piping is installed. Concrete thrust blocks must be installed at all elbows, tees, gate valves, and end hydrants. The point of ground entry of supply lines should also have thrust blocks installed (the inlet to the main supply line). As the required lateral flowrate decreases beyond each operating sprinkler, the size of the lateral beyond each sprinkler may also decrease. The figure below illustrates proper pipe sizing for this irrigation system design. 5 f - I Figure 1. Lateral Sizing Illustration For this system, 2" class 160 PVC pipe may be used as lateral pipe to supply the last two sprinklers on each lateral. This is based on the flowrate required to supply these sprinklers and the velocity of the fluid through a given diameter pipe for that flowrate. In the same manner, 3" class 160 PVC may be used to supply up to four sprinklers prior to the last two, as shown above. All sprinklers prior to these must be supplied by 4" class 160 PVC as specified. Calculations Precipitation Rate The precipitation rate (PR) should not exceed the infiltration rate of the soil. The (PR) is calculated as follows: PR— 96.3xQx 360 lxs w = Where: Q = Sprinkler Flowrate =21.8gpm PR 0.33 iph for full circle. 1=Lateral Spacing= 80 $ s = Sprinkler Spacing= 80 ft w=Arc Sprinkler Moves= 360'(full circle) Velocity in Pipe Y— Qx0.408 D' Where: V =Velocity= 6.11 fl/sec Worst case Q = System Flowrate =240 gpm (Assuming 11 Sprinklers Operating) D =Pipe Diameter=4 in Total Dynamic Head The Total Dynamic Head (TDH) is the sum of the friction losses in the pipe and fittings, plus elevation head and suction head losses.

Some epoxy coated fittings include stacks and hydrants as an integral part of the fitting. ,. Occasionally it may be necessary to connect PVC plastic pipe to steel or CA pipe. This connection can be made with a coupling called a transition or repair coupling. In-line valves can be supplied with connections to gasket pipe. Thrust blocking is required for gasket pipe. Most thrust blocks will be concrete.. Manufacturers recommended thrust blocks at any change in direction greater than- 100 .

There are a number of machines that can be used to prepare the trench for PVC plastic pipe. Soil types, moisture content, depth of trench required and type and diameter of pipe must be considered. Generally chain trenches, wheel trenches, backhoes , or vibrating plows will be used for trench preparation. The vibrating plow can only be used for solvent weld PVC pipe and generally is limited to the smaller diameter of pipe. Under most conditions the chain- trencher or wheel trencher will be faster than the backhoe. Where wide trenches for large pipe are required, the backhoe will be most satisfactory. If soil conditions permit, long stretches of open trench will expedite: pipe installation. However, if rain is forecast the pipe should be installed and the trench backfilled. To avoid sharp turns in the line at obstructions, trenches should be curved within limits of curvature of the pipe. -7- U_5,DEf ARTMEN7 Of-AGRICULTURE: -'-'—" `' ••"' •.'

The time required for the planned fluid level (permanent and temporary storage) to be reached may vary due to site conditions, weather, flushing operations, and the amount of fresh water added to the system. The designed temporary storage consists of 180 days storage for: ( 1) waste from animals and (2) excess rainfall after evaporation. Also included is storage for the 25 year - 24 hour storm for the location. The volume of waste generated from a given number of animals will be fairly constant throughout the year and from year to year , but excess rainfall will vary from year to year . The 25 year rainfall will not be a factor to consider in an annual pumping cycle, but this storage volume must always be available. A maximumielevation is determined in each design to begin pumping and this is usually the outlet invert of pipe(s) from -building(s) . If the outlet pipe is not installed at the elevation to begin pumping, a permanent marker must be installed at this elevation to indicate when pumping should begin. An elevation must be established to stop pumping to maintain lagoon treatment depth., Pumping can be started or stopped at any time between these two elevations for operating convenience as site conditions permit, such as weather, soils , crop, and equipment in order to apply waste without runoff or leaching. Land application of waste water is recognized as an acceptable method of disposal . Methods of application include solid set , center pivot , guns, and traveling gun irrigation. Care should be taken when applying waste to prevent damage to crops. The following items are to be carried out: 1 . It is strongly recommended that the treatment lagoon be pre- charged to 1/2 its capacity to prevent excessive odors during start-up. Pre-charging reduces the concentration of the initial waste entering the lagoon thereby reducing odors. Solids should be covered with effluent at all times. When precharging is complete, flush buildings with recycled lagoon liquid. Fresh water should not be used for flushing after initial filling . 2 . The attached waste utilization plan shall be followed. This plan recommends sampling and testing of waste (see attachment ) before land application. 3 . Begin temporary storage pump-out of the lagoon when fluid level reaches the elevation 45 . 0 as marked by permanent marker . Stop pump- out when the fluid level reaches elevation 42 . 9 . This temporary storage, less 25 yr- 24 hr storm, contains 39631 cubic feet or 296443 gallons . SHEET 1 OF 2 SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS ---------------------------------------------------------- FOUNDATION PREPARATION: --------------- The foundation area of the lagoon embankment and building pad shall be cleared of trees, logs, stumps, roots, brush, boulders, sod and rubbish. Satisfactory disposition will be made of all debris . The topsoil from the lagoon and pad area should be stripped and stockpiled for use on the dike and pad areas . After stripping, the foundation area of the lagoon embankment and building pad shall be thoroughly loosened prior to placing the first lift of fill material to get a good bond. EXCAVATION AND EARTHFILL PLACEMENT: ----------------------------------- The completed excavation and earthfill shall conform to the lines, grades, and elevations shown on the plans. Earthfill material shall be free olf material such as sod, roots, frozen soil , stones over 6 inches in diameter, and other objectionable material . To the extent they are suitable, excavated materials can be used as fill . The fill shall be brought up in approximately horizontal layers not to exceed 9 inches in thickness when loose and prior to compaction. Each layer will be compacted by complete coverage with the hauling and spreading equipment or standard tamping roller or other equivalent method. Compaction will be considered adequate when fill material is observed to consolidate to the point that settlement is not readily detectible . NOTE THE SPECIAL REQUIREMENTS FOR PLACEMENT OF LINERS IN THE LINER SECTION OF THIS SPECIFICATION. The embankment of the lagoon shall be installed using the more impervious materials from the required excavations. Construction of fill heights shall include 5 percent for settlement . Dikes over 15 feet in height and with an impoundment capacity of 10 acre-feet or more fall under the jurisdiction of the NC Dam Safety Law. The height is defined as the difference in elevation from the cWstructed height to the downstream toe of the dike . Precautions shall be taken during construction to prevent excessive erosion -and sedimentation. LINER: THE MINIMUM REQUIRED THICKNESS SHALL BE 1 . 6 ft . ------ ------------------------------------------------- NOTE: LINERS (PARTIAL OR FULL) ARE REQUIRED WHEN THE ATTACHED SOILS INVESTIGATION REPORT SO INDICATES OR WHEN UNSUITABLE MATERIAL IS ENCOUNTERED DURING CONSTRUCTION, A TYPICAL CROSS SECTION OF THE LINER IS INCLUDED IN THE DESIGN WHEN LINERS ARE REQUIRED BY THE SOILS REPORT. When areas of unsuitable material are encountered, they will be over- excavated below finish grade to the specified depth as measured perpendicular to the finish grade . The foundation shall be backfilled as specified to grade with a SCS approved material ( ie - CL,SC,CH) . REFER TO THE SOILS INVESTIGATION INFORMATION IN THE PLANS FOR SPECIAL CONSIDERATIONS. SHEET 2 OF 2 Soil liner material shall come from an approved borrow area. The minimum water content of the liner material shall be optimum moisture content which relates to that moisture content when the soil is kneaded in the hand it will form a ball which does not readily separate. Water shall be added to borrow as necessary to insure proper moisture content during placement of the liner . The moisture content of the liner material shall not be less than optimum water content during placement . The maximum water content relates to the soil material being too wet for efficient use of hauling equipment and proper compaction. Proper compaction 'of the liner includes placement in 9 inch lifts and compacted to at least 90 percent of the maximum ASTM D698 Dry Unit Weight of- the liner material . When smooth or hard,, the previous lift shall be scarified and moistened as needed before placement of the next lift . The single most important factor affecting the overall compacted perme- ability of a clay liner, other than the type of clay used for the liner , is the efficient construction processing of the compacted liner . The sequence of equipment use and the routing of equipment in an estab- lished paittern helps assure uniformity in the whole placement and compaction process. For most clay soils, a tamping or sheepsfoot roller is the preferable type of compaction equipment . The soil liner shall be protected from the discharge of waste outlet pipes . This can be done by using some type of energy dissipator(rocks ) or using flexible outlets on waste pipes . Alternatives to soil liners are synthetic liners and bentonite sealant . When these are specified, additional construction specifications are included with this Construction Specification. CUTOFF TRENCH: -------------- A cutoff trench shall be constructed under the embankment area when shown on a-4ypical cross section in the plans. The final depth of the cutoff trench shall be determined by observation of the foundation materials. VEGETATION: All exposed embankment and other bare constructed areas shall be seeded to the planned type of vegetation as soon as possible after construc- tion according to the seeding specifications . Topsoil should be placed on areas of the dike and pad to be seeded. Temporary seeding or mulch shall be used if the recommended permanent vegetation is out of season dates for seeding. Permanent vegetation should be established as soon as possible during the next period of approved seeding dates. REMOVAL OF EXISTING TILE DRAINS ------------------------------- When tile drains are encountered, the tile will be removed to a minimum of 10 feet beyond the outside toe of slope of the dike. The 'tile trench shall be backfilled and compacted with good material such as SC, CL, or CH.

This lagoon, as designed, meets SCS standards and specifications. It is the responsibility of the contractor and you to build the lagoon according to the design. You should contact the swine company to get assistance in the layout of the lagoon for construction. If you have any questions during construction, please contact this office or the swine company., Please be aware that SCS has not checked the excavation and fill volumes of dirt. The swine company has computed these figures and any questions regarding the amount of excavation should be directed to the company. SCS does not certify that excavation and fill volumes are correct. MPORTANT If you would like for the SCS to certify that the lagoon has been built to design specifications and meets SCS specifications and standards, personnel from this office must be present during the lagoon liner installation. Liners installed without SCS personnel onsite may be required to have testing performed by an engineering firm prior to certification. The reason for this requirement is that liners are very critical to the proper construction of the lagoon and the moisture content of the liner material as well as the method of installation and compaction greatly affect the performance of the liner. We will also need to conduct a final construction check prior to animal waste being put in the lagoon. State law requires that new and expanded operations have lagoons that meet the SCS ififtmum design specifications. In order to certify the lagoon, we must get bottom elevations as well as top of dike and sideslope readings. If given a few days notice;,we will try to schedule the construction checks prior to the contractor leaving the site;-however, since we schedule several days in advance, it is best if you let us know as soon as possible when you believe that a construction check will be needed. Also enclosed is a contractor certification that must be signed by the contractor once the lagoon is completed. We need this form returned to us before we certify that a lagoon meets our specifications. You may want to inform your contractor prior to beginning the job that you will need him to certify his work meets the design requirements. This approval is valid for six months from the date of this letter. If excavation and/or construction has not begun during this interval, a new site evaluation is required prior to construction if SCS certification is desired. If you have any questions concerning this design or the accompanying waste utilization plan, please contact us. s: 1� d(c. : ►�k� '1�'a s Al btu. �R,P--�(���R-Q..-J 6!�}��D Sincerely, In,L.Aw C.� Michael E.

AWS310482 System Calibration Information presented in manufacturer's charts are based on average operation conditions with relatively new equipment. Discharge rates and application rates change over time as equipment gets older and components wear. In particular, pump wear tends to reduce operating pressure and flow. With continued use, nozzle wear results in an increase in the nozzle opening which will increase the discharge rate while decreasing the wetted diameter. You should be aware that operating the system differently than assumed in the design will alter the application rate, diameter of coverage, and subsequently the application uniformity. For example, operating the system with excessive pressure results in smaller droplets, greater potential for drift, and accelerates wear of the sprinkler nozzle. Clogging of nozzles can result in pressure increase. Plugged intakes or crystallization of mainlines will reduce operating pressure. Operating below design pressure greatly reduces the coverage diameter and application uniformity. For the above reason, you should calibrate your equipment on a regular basis to ensure proper application rates and uniformity. Calibration at least once every three years is recommended. Calibration involves collecting and measuring flow at several locations in the application area. Any number of containers can be used to collect flow and determine the application rate. Rain gauges work best because they already have a graduated scale from which to read the application amount without having to perform additional calculations. However, pans, plastic buckets, jars, or anything with a uniform opening and cross-section can be used provided the liquid collected can be easily transferred to a scaled container for measuring. For stationary sprinklers, collection containers should be located randomly throughout the application area at several distances from sprinklers. For traveling guns, sprinklers should be located along a transect perpendicular to the direction of pull. Set out collection containers 25 feet apart along the transect on both sides of the gun cart. You should compute the average application rate for all nonuniformity of the application. On a windless day, variation between containers of more than 30 percent is cause for concern. You should contact your irrigation dealer or technical specialist for assistance. *Reprinted for Certification Training for Operations of Animal Waste Management Systems Manual 1 Maready Farm Inc. AWS310482 OPERATION & MAINTENANCE PLAN Proper lagoon management should be a year-round priority. It is especially important to manage levels so that you do not have problems during extended rainy and wet periods. Maximum storage capacity should be available in the lagoon for periods when the receiving crop is dormant (such as wintertime for bermudagrass) or when there are extended rainy spells such as a thunderstorm season in the summertime. This means that at the first sign of plant growth in the later winter/ early spring, irrigation according to a farm waste management plan should be done whenever the land in dry enough to receive lagoon liquid. This will make storage space available in the lagoon for future wet periods. In the late summer/ early fall the lagoon should be pumped down to the low marker (see Figure 2-1) to allow for winter storage. Every effort should be made to maintain the lagoon close to the minimum liquid level as long as the weather and waste utilization plan will allow it. Waiting until the lagoon has reached its maximum storage capacity before starting to irrigated does not leave room for storing excess water during extended wet periods. Overflow from the lagoon for any reason except a 25-year, 24-hour storm is a violation of state law and subject to penalty action. The routine maintenance of a lagoon involves the following: • Maintenance of a vegetative cover for the dam. Fescue or common bermudagrass are the most common vegetative covers. The vegetation should be fertilized each year, if needed, to maintain a vigorous stand. The amount of fertilized applied should be based on a soils test, but in the event that it is not practical to obtain a soils test each year, the lagoon embankment and surrounding areas should be fertilized with 800 pounds per acre of 10-10-10, or equivalent. • Brush and trees on the embankment must be controlled. This may be done by mowing, spraying, grazing, chopping, or a combination of these practices. This should be done at least once a year and possibly twice in years that weather conditions are favorable for heavy vegetative growth. NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter the lagoon water. Such chemicals could harm the bacteria in the lagoon that are treating the waste. Maintenance inspections of the entire lagoon should be made during the initial filling of the lagoon and at least monthly and after major rainfall and storm events. Items to be checked should include, as a minimum, the following: Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes --look for: 1. separation of joints 2. cracks or breaks 3. accumulation of salts or minerals 4. overall condition of pipes 2 Maready Farm Inc. AWS310482 Lagoon surface -- look for: 1. undesirable vegetative growth 2. floating or lodged debris Embankment -- look for: 1. settlement, cracking, or"jug" holes 2. side slope stability--slumps or bulges 3. wet or damp areas on the back slope 4. erosion due to lack or vegetation or as a result of wave action 5. rodent damage Larger lagoons may be subject to liner damage due to wave action caused by strong winds. These waves can erode the lagoon sidewalls, thereby weakening the lagoon dam. A good stand of vegetation will reduce the potential damage caused by wave action. If wave action causes serious damage to a lagoon sidewall, baffles in the lagoon may be used to reduce the wave impacts. Any of these features could lead to erosion and weakening of the dam. If your lagoon has any of these features, you should call an appropriate expert familiar with design and construction of waste lagoons. You may need to provide a temporary fix if there is a threat of a waste discharge. However, a permanent solution should be reviewed by the technical expert. Any digging into a lagoon dam with heavy equipment is a serious undertaking with potentially serious consequences and should not be conducted unless recommended by an appropriate technical expert. Transfer Pumps -- check for proper operation of: 1. recycling pumps 2. irrigation pumps Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding noise, or a large amount of vibration, may indicate that the pump is in need of repair or replacement. NOTE: Pumping systems should be inspected and operated frequently enough so that you are not completely "surprised" by equipment failure. You should perform your pumping system maintenance at a time when your lagoon is at its low level. This will allow some safety time should major repairs be required. Having a nearly full lagoon is not the time to think about switching, repairing, or borrowing pumps. Probably, if your lagoon is full, your neighbor's lagoon is full also. You should consider maintaining an inventory of spare parts or pumps. • Surface water diversion features are designed to carry all surface drainage waters (such as rainfall runoff, roof drainage, gutter outlets, and parking lot runoff) away from your lagoon and other waste treatment or storage structures. The only water that should be coming from your lagoon is that which comes from your flushing (washing) system pipes and the rainfall that hits the lagoon directly. You should inspect your diversion system for the following: 1. adequate vegetation 2. diversion capacity 3. ridge berm height 3 Maready Farm Inc. AWS310482 Identified problems should be corrected promptly. It is advisable to inspect your system during or immediately following a heavy rain. If technical assistance is needed to determine proper solutions, consult with appropriate experts. You should record the level of the lagoon just prior to when rain is predicted, and then record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will give you an idea of how much your lagoon level will rise with a certain rainfall amount (you must also be recording your rainfall for this to work). Knowing this should help in planning irrigation applications and storage. If your lagoon rises excessively, you may have an overflow problem from a surface water diversion or there may be seepage into the lagoon from the surrounding land. Lagoon Operation Startup: 1. Immediately after construction establish a complete sod cover on bare soil surfaces to avoid erosion. 2. Fill new lagoon design treatment volume at least half full of water before waste loading begins, taking care not to erode lining or bank slopes. 3. Drainpipes into the lagoon should have a flexible pipe extender on the end of the pipe to discharge near the bottom of the lagoon during initial filling or another means of slowing the incoming water to avoid erosion of the lining. 4. When possible, begin loading new lagoons in the spring to maximize bacterial establishment (due to warmer weather). 5. It is recommended that a new lagoon be seeded with sludge from a healthy working swine lagoon in the amount of 0.25 percent of the full lagoon liquid volume. This seeding should occur at least two weeks prior to the addition of wastewater. 6. Maintain a periodic check on the lagoon liquid pH. If the pH falls below 7.0, add agricultural lime at the rate of 1 pound per 1000 cubic feet of lagoon liquid volume until the pH rises above 7.0. Optimum lagoon liquid pH is between 7.5 and 8.0. 7. A dark color, lack of bubbling, and excessive odor signals inadequate biological activity. Consultation with a technical specialist is recommended if these conditions occur for prolonged periods, especially during the warm season. Loading: The more frequently and regularly that wastewater is added to a lagoon, the better the lagoon will function. Flush systems that wash waste into the lagoon several times daily are optimum for treatment. Pit recharge systems, in which one or more buildings are drained and recharged each day, also work well. 4 Maready Farm Inc. AWS310482 • Practice water conservation --- minimize building water usage and spillage from leaking waterers, broken pipes and washdown through proper maintenance and water conservation. • Minimize feed wastage and spillage by keeping feeders adjusted. This will reduce the amount of solids entering the lagoon. Management: • Maintain lagoon liquid level between the permanent storage level and the full temporary storage level. • Place visible markers or stakes on the lagoon bank to show the minimum liquid level and the maximum liquid level. (Figure 2-1). • Start irrigating at the earliest possible date in the spring based on nutrient requirements and soil moisture so that temporary storage will be maximized for the summer thunderstorm season. Similarly, irrigate in the late summer / early fall to provide maximum lagoon storage for the winter. • The lagoon liquid level should never be closer than 1 foot to the lowest point of the dam or embankment. • Don not pump the lagoon liquid level lower than the permanent storage level unless you are removing sludge. • Locate float pump intakes approximately 18 inches underneath the liquid surface and as far away from the drainpipe inlets as possible. • Prevent additions of bedding materials, long-stemmed forage or vegetation, molded feed, plastic syringes, or other foreign materials into the lagoon. • Frequently remove solids from catch basins at end of confinement houses or wherever they are installed. • Maintain strict vegetation, rodent, and varmint control near lagoon edges. • Do not allow trees or large bushes to grow on lagoon dam or embankment. • Remove sludge from the lagoon either when the sludge storage capacity is full or before it fills 50 percent of the permanent storage volume. • If animal production is to be terminated, the owner is responsible for obtaining and implementing a closure plan to eliminate the possibility of a pollutant discharge. Sludge Removal: Rate of lagoon sludge buildup can be reduced by: 5 Maready Farm Inc. AWS310482 • proper lagoon sizing, • mechanical solids separation of flushed waste, • gravity settling of flushed waste solids in an appropriately designed basin, or • minimizing feed wastage and spillage. Lagoon sludge that is removed annually rather than stored long term will: • have more nutrients, • have more odor, and • require more land to properly use the nutrients. Removal techniques: • Hire a custom applicator. • Mix the sludge and lagoon liquid with a chopper-agitator impeller pump through large - bore sprinkler irrigation system onto nearby cropland; and soil incorporate. • Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland; mix remaining sludge; pump into liquid sludge applicator; haul and spread onto cropland or forageland; and soil incorporate. • Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland; dredge sludge from lagoon with dragline or sludge barge; berm an area beside lagoon to receive the sludge so that liquids can drain back into lagoon; allow sludge to dewater; haul and spread with manure spreader onto cropland or forageland; and soil incorporate. Regardless of the method, you must have the sludge material analyzed for waste constituents just as you would your lagoon water. The sludge will contain different nutrient and metal values from the liquid. The application of the sludge to fields will be limited by these nutrients as well as any previous waste applications to that field and crop requirement. Waste application rates will be discussed in detail in Chapter 3. When removing sludge, you must also pay attention to the liner to prevent damage. Close attention by the pumper or drag-line operator will ensure that the lagoon liner remains intact. If you see soil material or the synthetic liner material being disturbed, you should stop the activity immediately and not resume until you are sure that the sludge can be removed without liner injury. If the liner is damaged it must be repaired as soon as possible. Sludge removed from the lagoon has a much higher phosphorus and heavy metal content than liquid. Because of this it should probably be applied to land with low phosphorus and metal levels, as indicated by a soil test, and incorporated to reduce the chance of erosion. Note that if the sludge is applied to fields with very high soil-test phosphors, it should be applied only at rates equal to the crop removal of phosphorus. As with other wastes, always have your lagoon sludge analyzed for its nutrient value. 6 Maready Farm Inc. AWS310482 The application of sludge will increase the amount of odor at the waste application site. Extra precaution should be used to observe the wind direction and other conditions which could increase the concern of neighbors. Possible Causes of Lagoon Failure Lagoon failures result in the unplanned discharge of wastewater from the structure. Types of failures include leakage through the bottom or sides, overtopping, and breach of the dam. Assuming proper design and construction, the owner has the responsibility for ensuring structure safety. Items which may lead to lagoon failures include: • Modification of the lagoon structure -- an example is the placement of a pipe in the dam without proper design and construction. (Consult an expert in lagoon design before placing any pipes in dams.) • Lagoon liquid levels--high levels are a safety risk. • Failure to inspect and maintain the dam. • Excess surface water flowing into the lagoon. • Liner integrity -- protect from inlet pipe scouring, damage during sludge removal, or rupture from lowering lagoon liquid level below groundwater table. NOTE: If lagoon water is allowed to overtop the dam, the moving water will soon cause gullies to form in the dam. Once this damage starts, it can quickly cause a large discharge of wastewater and possible dam failure. Maready Farm Inc. AWS310482 EMERGENCY ACTION PLAN PHONE NUMBERS DIVISION OF WATER QUALITY (DWQ) 910-796-7215 EMERGENCY MANAGEMENT SERVICES (EMS) 910-296-2160 SOIL AND WATER CONSERVATION DISTRICT (SWCD) 910-296-2120 NATURAL RESOURCES CONSERVATION SERVICE (NRCS) 910-296-2121 COOPERATIVE EXTENSION SERVICE (CES) 910-296-2143 This plan will be implemented in the event that wastes from your operation are leaking, overflowing or running off site. You should not wait until wastes reach surface waters or leave your property to consider that you have a problem. You should make every effort to ensure that this does not happen. This plan should be posted in an accessible location for all employees at the facility. The following are some action items you should take. 1. Stop the release of wastes. Depending on the situation, this may or may not be possible. Suggested responses to some possible problems are listed below. A. Lagoon overflow-possible solutions are: a) Add soil to berm to increase elevation of dam. b) Pump wastes to fields at an acceptable rate. c) Stop all flow to the lagoon immediately. d) Call a pumping contractor. e) Make sure no surface water is entering lagoon. B. Runoff from waste application field-actions include: a) Immediately stop waste application. b) Create a temporary diversion to contain waste. c) Incorporate waste to reduce runoff. d) Evaluate and eliminate the reason(s)that cause the runoff. e) Evaluate the application rates for the fields where runoff occurred. C. Leakage from the waste pipes and sprinklers-action include: a) Stop recycle pump. b) Stop irrigation pump. c) Close valves to eliminate further discharge. d) Repair all leaks prior to restarting pumps. D. Leakage from flush systems, houses, solid separators-action include: a) Stop recycle pump. b) Stop irrigation pump. c) Make sure siphon occurs. d) Stop all flow in the house, flush systems, or solid separators. E. Leakage from base or sidewall of lagoon. Often this is seepage as opposed to flowing leaks- possible action: a) Dig a small sump or ditch from the embankment to catch all seepage, put in a submersible pump, and pump back to lagoon. b) If holes are caused by burrowing animals, trap or remove animals and fill holes and compact with a clay type soil. 8 Maready Farm Inc. AWS310482 c) Have a professional evaluate the condition of the side walls and the lagoon bottom as soon as possible. 2. Assess the extent of the spill and note any obvious damages. a. Did the waste reach surface waters? b. Approximately how much was released and for what duration? c. Any damage notes, such as employee injury, fish kills, or property damage? d. Did the spill leave the property? e. Does the spill have the potential to reach surface waters? f. Could a future rain event cause the spill to reach surface waters? g. Are potable water wells in danger(either on or off the property)? h. How much reached surface waters? 3. Contact appropriate agencies. a. During normal business hours call your DWQ regional office; Phone #, After hours, emergency number: (919) 733-3942. Your phone call should include: your name, facility number, telephone number, the details of the incident from item 2 above, the exact location of the facility, the location or direction of the movement of the spill, weather and wind conditions. The corrective measures that have been under taken, and the seriousness of the situation. b. If the spill leaves property or enters surface waters, call local EMS phone number. c. Instruct EMS to contact local Health Department. d. Contact CE's phone number, local SWCD office phone number and the local NRCS office for advice/technical assistance phone number. 4. If none of the above works call 911 or the Sheriff's Department and explain your problem to them and ask the person to contact the proper agencies for you. 5. Contact the contractor of your choice to begin repair or problem to minimize offsite damage. a. Contractors Name: Agriment Services,Inc. b. Contractors Address: Po Box 1096, Beulaville,NC 28518 c. Contractors Phone: (252)568-2648 6. Contact the technical specialist who certified the lagoon (NRCS, Consulting Engineer, etc.) a. Name: Geno Kennedy b. Phone: (910)289-0395 7.

Primary Secondary Routine Mortality Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal death. The burial must be at least 300 feet from any flowing stream or public body of water (G.S.106-403). The bottom of the burial pit should beat least one foot above the seasonal high water table. Attach burial location map and plan. Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC 13B .0200. Rendering at a rendering plant licensed under G.S. 106-168.7. Complete incineration according to 02 NCAC 52C .0102. A composting system approved and permitted by the NC Department of Agriculture & Con- sumer Services Veterinary Division (attach copy of permit). If compost is distributed off-farm, additional requirements must be met and a permit is required from NC DEQ. a In the case of dead poultry only, placing in a disposal pit of a size and design approved by the NC Department of Agriculture&Consumer Services (G.S. 106-549.70). Any method which, in the professional opinion of the State Veterinarian, would make possible the salvage of part of a dead animal's value without endangering human or animal health. (Written approval by the State Veterinarian must be attached). Mass Mortality Plan Mass mortality plans are required for farms covered by an NPDES permit. These plans are also recommended for all animal operations. This plan outlines farm-specific mortality man- agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup- ports a variety of emergency mortality disposal options; contact the Division for guidance. • A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated when numbers of dead animals exceed normal mortality rates as specified by the State Veterinarian. • Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary Division regulations and guidance. • Mass burial sites are subject to additional permit conditions (refer to facility's animal waste management system permit). • In the event of imminent threat of a disease emergency, the State Veterinarian may enact additional temporary procedures or measures for disposal according to G.S. 106-399.4.
