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 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. 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 specific 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.

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 3965.76 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 19828.8 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 66 acreas of land. If you apply the sludge to corn at a rate of 125 pounds per acre, you will need 158.6304 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.

Parts of this pivot area, as well as the Pierce tract are used under agreement with an adjacent landowner. It is recommended that the land in row crops be split evenly between corn and soybeans each spring. Producer must overseed a minimum of 40 acres or row crop land behind soybeans each year, unless lagoon levels dictate, and are verified by a technical specialist, that this is not needed. This overseed must be either grazed or cut for hay prior to corn planting. 7of8 NUTRIENT UTILIZATION PLAN CERTIFICATION Name of Farm: Doug Bond Farm Owner: Doug Bond Manager: Owner/Manager Agreement: I/we understand and will follow and implement the specifications and the operation and maintenance procedures established in the approved animal waste nutrient management plan for the farm named above.

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, he/she 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, recievinq 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 surface is frozen. 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. 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 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. 12 Animal waste shall not be applied closer than 100 feet to wells. 13 Animal waste shall not be applied closer than 200 feet of dwellings other than those owned by the landowner. 14 Waste shall be applied in a manner not to reach other property and public right-of-ways. 15 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 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. 16 Domestic and industrial waste from washdown facilities, showers, toilets, sinks, etc., shall not be discharged into the animal waste management system. 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. 19 Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular basis to prevent breakdowns, leaks and spills. A regular maintenance checklist should be kept on site. 20 Animal waste can be used in a rotation that includes vegetables and other crops for direct 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. 21 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 managed to maintain the liquid level between the markers. A marker will be required to mark the maximum storage volume for waste storage ponds. 22 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 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.

Sheet6 Narrative of Irrigation System Operation This is a "wetted acreage" determination for an existing facility. This facility uses travelers and two new center pivots. The pivots replaced some of the previous traveler pulls. The acres were calculated based on the equipment specified and the charts created by NCSU for calculating Area Allowances for Hard Hose Traveler Systems. Refer to owner's manual and irrigation dealer for information on maintenance, winterization, and operation of system.

The time required for the planned fluid level to be reached (permanent + temporary storage) may vary due to flushing operations and the amount of fresh water to be 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 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 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 minimum treatment depth (6 feet) . Pumping can be started or stopped any time between these two elevations for operating convenience as site conditions permit (weather, soils, crop, and equipment 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 runoff from the field or damage to crops. The following items are to be carried out: 1 . It is strongly recommended tha 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 pre- charging is completed, 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 B) before land application. r 1 3 . Begin pump-out of the lagoon when fluid level reaches eleva- tion 49 . 90 as marked by permanent markers. Stop pump-out when the fluid level reaches elevation 47 . 70 or before fluid depth is less than 6 feet deep (this prevents the loss of favorable bacteria) . The design temporary storage, less 25 year storm is 180537 cubic feet or 1350419 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 . 4 inches per hour. 5 . Keep vegetation on 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 100 feet cropland buffer or 25 feet of grass vegetated buffer around waste utilization fields, particularly adjacent to ponds, lakes, streams, open ditches, etc. Do not pump within 300 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 Environ- mental Management, has the responsibility for enforcing this law.

DESIGNED BY APPROVED BY• DATE- G DATE : NOTE: SEE ATTACHED WASTE UTILIZATION PLAN COMMENTS: --------------------------------------------------- ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 0 OPERATION AND MAINTENANCE PLAN ------------------------------ This_ lagoon is designed for waste treatment (permanent storage) with min . odor control . The time reouired 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 storaoe 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 inches of excess rainfall which is equal to or exceeds the highest 6 months ev.cess 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 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 minimum treatment depth (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. 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. HEBIN pump-out of the lagoon when fluid level reaches eleva- tion . 48.80 as marked by permanent marker . STOP pump-out when the fluid level reaches elevation 46.70 or before the fluid depth is less than 7.20 feet deep ( this prevents the loss of favorable bacteria) . The design temporary storage, less 25 year/ 24 hour storm is 178,446 cubic feet or 1 ,334,776 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 inch 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 . B . 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 Environ— mental Management , has the responsibility for enforcing this law. SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS ---------------------------------------------------------- Clearing : A11 trees and brush shall be removed from the construction area before any excavating or fill is started. Stumps will be removed within the area of the foundation of the embankment and fill areas and all excavated areas . All stumps and roots exceeding one ( 1 ) inch in diameter shall be removed to a minimum depth of one ( 1 ) foot . Satisfactory disposition will be made of all debris . The foundation area shall be loosened thoroughly before placement of embankment material . Cut-off Trench: --------------- A cut-off trench (when specified) shall be installed as shown in the plans . Construction : ------------- Construction of excavated and earthfill areas shall be performed to the neat lines and grades as planned. Deviations from this will require prior approval of the SCS . Earthfill shall not be placed in standing water and reasonable compaction of the fills shall be performed by the construction equipment or sheeps-foot roller during placement . The embankment of the lagoon shall be installed using the more impervious materials . Construction of fill heights shall include ten ( 10 ) percent for settlement . To protect against seepage, when areas of unsuitable material are encountered, they will need to be excavated a minimum of one ( 1 ) foot below grade and backfilled and compacted with a suitable material ( ie-CL,SC,CH) . Refer to the soils investigation information in the plans for special considerations . Precautions should be taken during construction to prevent excessive erosion and sedimentation. Vegetation: All exposed embankment and other bare constructed areas shall be seeded to the planned type of vegetation as soon as possible after construction. :�1_ir1111 ivi CA`ifv � . iali.

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 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 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 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 • 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 • 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 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. EMERGENCY ACTION PLAN PHONE NUMBERS DIVISION OF WATER QUALITY (DWQ) �0--Z9�1atS EMERGENCY MANAGEMENT SERVICES (EMS) \'t 0 - 24(e- SOIL AND WATER CONSERVATION DISTRICT (SWCD) qt5- .�qu_ AkD 0 NATURAL RESOURCES CONSERVATION SERVICE (NRCS) °t tO - pq 6-at d COOPERATIVE EXTENSION SERVICE (CES) 9to - act 6- a11A3 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. c) Have a professional evaluate the condition of the side walls and the lagoon bottom as soon as possible. 8 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.

(Landowner Signature) 13 Version—November 26,2018 Mortality Management Methods Indicate which method(s) will be implemented. When selecting multiple methods indicate a primary versus secondary option. Methods other than those listed must be approved by the State Veterinarian. Primary Secondar 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 be at 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 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 DEC. 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 opinioneof 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.
