The plant nutrients in the animal waste should be used to reduce the amount of commercial fertilizer required for the crops in the fields where the waste is to be applied. 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 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 be applied to land eroding at less 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 result in runoff to 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 crop production and to reduce the potentia 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. 1 of 8 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 application 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. In some cases you may want to have plant analysis made,which 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 crop type. Lime must be applied to maintain pH in the optimum range for speck crop production. This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC 2H .0217 adopted by the Environmental Management Commission.

The farm should produce adequate plant available nitrogen to satisfy the requirements of the crops listed above. 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 addresses all nutrients. This plan only addresses nitrogen. In interplanted fields ( i.e. small grain, etc, interseeded in bermuda),forage must be removed through grazing, hay, and/or silage. Where grazing, plants should be grazed when they reach a height of six to nine 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 reach maturity, especially late in the season (i.e. April or May). Shading may result if small grain gets too high and this will definately interfere with 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 cut to a height of about two inches before drilling for best results.

Actual total acres in the fields 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. 4 of 8 SLUDGE APPLICATION: The following table describes the annual nitrogen accumulation rate per animal in the lagoon sludge Farm Specifications PAN/ r/animal Farm Totall r Farrow to Wean 0.84 Farrow to Feeder 1 Farrow to Finish 4.1 Wean to Feeder 0.072 7344 Feeder to Finish 0.36 2643.84 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 2643,84 pounds of plant available nitrogen per year will accumulate in the lagoon sludge based on the rates of accumulation listed above. If you remove the sludge every 5 years,you will have approximately 13219.2 pounds of plant available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the rate of 300 pounds of nitrogen per acre, you will need 44 acreas of land. If you apply the sludge to corn at a rate of 125 pounds per acre,you will need 105.7536 acres of land. Please note that these are only estimates of the PAN produced and the land required to utilize that PAN. Actual values may only be determined by sampling the sludge for plant available nitrogen content prior to application Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific application fields designated for sludge application at time of removal. 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 of the soil at the time of irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of the crop. 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 the preceding table. Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid. *This is the maximum application amount allowed for the soil assuming the amount of nitrogen allowed for the crop is not over applied. In many situations,the application amount shown cannot be applied because of the nitrogen limitation. The maximum application amount shown can be applied under optimum soil conditions. 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 instance should the volume of the waste 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. It is the responsibility of the producer and waste applicator to ensure that the spreader equipment is operated properly to apply the correct rates to the acres 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 receive the waste analysis report for assistance in determining the amount of waste per acre and the proper application prior to applying the waste. 5of8 Application Rate Guide The following is provided as a guide for establishing application rates and amounts.

Any discharge of waste which reaches surface water is prohibited. 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 the waste. If the producer does not own adequate land to properly dispose of the waste, helshe shall provide evidence 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 waste production facility to secure an update of the Nutrient Utilization Plan when there is a change in the operation, increase in the number of animals, method of application, recieving crop type, or available land. 3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic crop yields based upon soil type, available moisture, historical data, climatic conditions, and level of management, unless there are regulations that restrict the rate of applications 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 eroding at more than 5 tons per acre per year but less than 10 tons per acre per year provided grass filter strips are Installed where runoff leaves the field (See USDA, NRCS Field Office Technical Guide Standard 393 - Filter Strips). 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 land application field. 6 When animal waste is to be applied on acres subject to flooding, waste will be soil incorporated on conventionally tilled cropland. When waste is 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 such that runoff does not occur offsite or to 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 and flies. 8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the 1 of 3 NUTRIENT UTILIZATION PLAN _ REQUIRED SPECIFICATIONS (continued) 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 Nutrients from waste 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 dormancy. Any new swine facility sited on or after October 1, 1995 shall comply with the following: 11 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 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. Animal waste shall not be applied closer than 100 feet to wells. 12 Animal waste shall not be applied closer than 200 feet of dwellings other than those 13 owned by the landowner. Waste shall be applied in a manner not to reach other property and public right-of-ways. 14 Animal waste shall not be discharged into surface waters, drainageways, or wetlands by discharge or by over-spraying. Animal waste may be applied to prior converted cropland 15 provided the fields have been approved as a land application site by a "technical specialist'. Animal waste shall not be applied on grassed waterways that discharge directly into water courses, and on other grassed waterways, waste shall be applied at agronomic rates in a manner that causes no runoff or drift from the site. Domestic and industrial waste from washdown facilities, showers, toilets, sinks, etc., shall not be discharged into the animal waste management system. 16 2of3 NUTRIENT UTILIZATION PLAN REQUIRED SPECIFICATIONS (continued) 17 A protective cover of appropriate vegetation will be established on all disturbed areas (lagoon embankments, berms, pipe runs, etc.). Areas shall be fenced, as necessary, to protect the vegetation. Vegetation such as trees, shrubs, and other woody species, etc., are limited to areas where considered appropriate. Lagoon areas should be kept mowed and accessible. Berms and structures should be inspected regularly for evidence of erosion, leakage, or discharge. 18 If animal production at the facility is to be suspended or terminated, the owner is responsible for obtaining and implementing a "closure plan" which will eliminate the possibility of an illegal discharge, pollution and erosion. Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular 19 basis to prevent breakdowns, leaks and spills. A regular maintenance checklist should be kept on site. Animal waste can be used in a rotation that includes vegetables and other crops for direct 20 human consumption. However, if animal waste is used on crops for direct human consumption, it should only be applied pre-plant with no further applications of animal waste during the crop season. Highly visible markers shall be installed to mark the top and bottom elevations of the temporary storage (pumping volume) of all waste treatment lagoons. Pumping shall be 21 managed to maintain the liquid level between the markers. A marker will be required to mark the maximum storage volume for waste storage ponds. Waste shall be tested within 60 days of utilization and soil shall be tested at least annually at crop sites where waste products are applied. Nitrogen shall be the rate-determining 22 nutrient, unless other restrictions require waste to be applied based on other nutrients, resulting in a lower application rate than a nitrogen based rate. Zinc and copper levels in the soil shall be monitored and alternative crop sites shall be used when these metals approach excessive levels. pH shall be adjusted and maintained for optimum crop production. Soil and waste analysis records shall be Kept for a minimum of five years. Poultry dry waste application records shall be maintained for a minimum of three years. Waste application records for all other waste shall be maintained for a minimum of five years.

Box 759 Rose Hill, NC 28458 Farm Operator: Stanley James Date: 11/11/93 OPERATION AND MAINTENANCE PLAN ----------------------- This lagoon is designed for waste treatment (permanent storage) with minimum odor control. The time required for the planned fluid level to be reached (permanent + temporary storage) may vary due to soil conditions, flushing operations, and the amount of fresh water added to the system. The designed 6 months temporary storage is an estimated volume based on: 1) waste from animals 2) excess rainfall after evaporation and 3) the largest 24 hour (one day) rainfall that occurs on the average of once every 25 years. The volume of waste generated from a given number of animals will be fairly constant throughout the year and from year to year. This estimate is based on 7.0 inches of excess rainfall which is equal to or exceeds the highest 6 months excess in a year. The average annual excess rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess rainfall will need to be pumped each 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 maximum elevation is determined in each design to begin pumping and this is usually the outlet invert of pipe(s) from the building(s). If the outlet pipe is not installed on the elevation to begin pumping, a permanent marker must be installed on this elevation to indicate when pumping should begin. An elevation must be established to stop pumping to maintain the minimum treatment depth of 6 feet. 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. MURPHY FARMS, INC. Page 2 P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Stanley James OPERATION AND MAINTENANCE PLAN (continued) ----------------------- The following items are to be carried out: 1. It is strongly recommended that the treatment lagoon be precharged to 1/2 of its capacity to prevent excessive odors during start—up. Precharging 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 pump—out of the lagoon when fluid level reaches elevation 47.30 feet as marked by the permanent marker. Stop pump—out of the lagoon when fluid level reaches elevation 44.90 feet or before the fluid depth is less than 9.40 feet deep (this prevents the loss of favorable bacteria). The designed temporary storage volume less the 25 year — 24 hour storm volume is 168,952 cubic feet or 1,263,763 gallons. As stated before, this volume will vary considerably from year to year. 4. The recommended maximum amount to apply per irrigation is one (1) inch and the recommended maximum application rate is 0.3 inches per hour. 5. Keep vegetation on the embankment and areas adjacent to the lagoon mowed annually. Vegetation should be fertilized as needed to maintain a vigorous stand. 6. Repair any eroded areas or areas damaged by rodents and establish in vegetation. 7. All surface runoff is to be diverted from the lagoon to stable outlets. 8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization fields adjacent to perennial streams. Waste will not be applied in open ditches. Do not pump within 200 feet of a residence or within 100 feet of a well. 9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters of the United States. The Department of Environment, Health and Natural Resources, Division of Environmental Management, has the responsibility for enforcing this law. MURPHY FARMS, INC. Page 1 P.O.

The estimated high water table elevation = 41.0 Feet, +/— Using the Unified Classification System, the results of the borings are as follows: Boring #1: N 49+53 / E 47+15 0 Ft. — 2 Ft. — SC material (clayey sands; sand—clay mixtures) 2 Ft. — 11 Ft. — SM material (silty sand (light brown to white in color)) Boring #2: N 49+95 / E 49+17 0 Ft. — 2 Ft. — SC material (clayey sands; sand—clay mixtures) 2 Ft. — 9 Ft. — SM material (silty sand (light brown to white in color)) Boring #3: N 48+33 / E 50+18 0 Ft. — 1 Ft. — SC material (clayey sands; sand—clay mixtures) 1 Ft. — 9 Ft. — SM material (silty sand (light brown to white in color)) Based on the results of these borings, the soils available on this site are not suitable to be used as embankment material for the lagoon site. A suitable clay material (ie — CL,SC,CH) for the liner will be required for this site. Ground water may be a problem during construction. MURPHY FARMS, INC. Page 1 P.O.

DESIGNED BY: APPROVED BY; , DATE: DATE: NOTE: SEE ATTACHED WASTE UTILIZATION PLAN COMMENTS: — ,ne LO 11 ------------------------------ This lagoon is designed for waste treatment ( permanent storage) acid 180 days of temporary storage. 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 fo" : ( 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 Zoi; be a factor to consider in an annual pumping cycle, but this stcrage volume must always be available. A maximum elevation 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 IDE 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 shoulJ 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 le,rel reaches the elevation 50. 8 as marked by permanent marker. sto ) pump- out when the fluid level reaches elevation 48. 8 . This temporary storage, less 25 yr- 24 hr storm, contains 179677 cubic feet or 1343982 gallons. 4. The recommended maximum amount to apply per irrigation is one ( 1 ) inch and the recommended maximum application rate is 0. 3 inch per hour. Refer to the waste utilization plan for further de':ai.ls. 5. Keep vegetation on the embankment and areas adjacent to the lagoon mowed annually. Vegetation should be fertilized as needed to maintain a vigorous stand. 6. Repair any eroded areas or areas damaged by rodents and establish in vegetation. 7. All surface runoff is to be diverted from the lagoon to Stahl? outlets. 8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization fields adjacent to perennial streams. Waste will not be applied in open ditches. Do not pump within 200 feet of a residence or within 100 feet of a well. Waste shall be applied in a manner not to reach other property and public right-of-ways. 9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters of the United States. The Department of Environment, Health, and Natural Resources, Division of Environ- mental Management, has the responsibility for enforcing this law. SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS ---------------------------------------------------------- FOUNDATION PREPARATION: ----------------------- The foundation area of the lagoon embankment and building pad sha-1 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 he 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 of material such as sod, roots, frozen soil, stones over 6 inches in diameter, and other objectionable material. To the e:ttent they are suitable, excavated materials can be used as fill. The :`il.l shall be brought up in approximately horizontal layers not to exceed 9 inches in thickness when loose and prior to compaction. Each lay,=r 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 obse --ved to consolidate to the point that settlement is not readily detectLble. NOTE THE SPECIAL REQUIREMENTS FOR PLACEMENT OF LINERS IN THE LINE: SECTION OF THIS SPECIFICATION. The embankment of the lagoon sha1L 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 tie NC Dam Safety Law. The height is defined as the difference in eletiation from the constructed height to the downstream toe of the dike. Precautions shall be taken during construction to prevent exceSE:iae erosion and sedimentation. LINER: THE MINIMUM REQUIRED THICKNESS SHALL BE 1. 8 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. _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 kieaded 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 c )nt:ent during placement of the liner. The moisture content of the liner material shall not be less than optimum water content during plac,ament. The maximum water content relates to the soil material being toc +et for efficient use of hauling equipment and proper compaction. Fr )per compaction of the liner includes placement in 9 inch lifts and compacted to at least 90 percent of the maximum ASTM DG98 Dry Uni : Weight of the liner material. When smooth or hard, the previous Lift shall be scarified and moistened as needed before placement of th,e next lift. The single most important factor affecting the overall compactec perme- ability of a clay liner, other than the type of clay used for tYe liner, is the efficient construction processing of the compactec liner. The sequence of equipment use and the routing of equipment in ar. =stab- lished pattern helps assure uniformity in the whole placement ar.d 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 oL:tlet 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 specificationE; are included with this Construction Specification. CUTOFF TRENCH : -------------- A cutoff trench shall be constructed under the embankment area when shown on a typical cross section in the plans. The final depth of the cutoff trench shall be determined by observation of the foundat__on 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 o- mulch shall be used if the recommended permanent vegetation is out of Beason dates for seeding. Permanent vegetation should be established sas 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 sucz as SC, CL, or CH.
