Wednesday,August 16,2017 Updated. 411112018 Producer: E&L Properties of Dudley, NC,LLC. Farris Name : Rose Brothers 730 Emmaus church Road Dudley,NC 28333 Telephone#: (919)222-80BO Type of Operation : Wean to Feeder Swine Number of Animals: 6400 pigs design capacity Application Method: Irrigation The waste from your animal facility must be land applied at a specified rate to prevent pollution of surface and/or groundwater. 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 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. Always apply waste based on the needs of the crop to be grown and the nutrient contents of the waste. Do not apply more nitrogen than the crop can utilize. Soil types are important as they have different infiltration rates, leaching potentials, cation exchange capacities, and avaialable water holding capacities. Normally waste shall not be applied to land eroding at greater than 5 tons per acre per year. With special pre-cautions, waste may be applied to land eroding at up to 10 tons per acre per year. 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 DEM regulations. Wind conditions should also be considered to avoid drift and downwind odor problems. 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 to bare ground not more than 30 days prior to planting. Injecting the waste or disking will conserve nutrients and reduce odor problems. This plan is based on waste application through irrigation for this is the manner in which you have chosen to apply your waste. If you choose to inject the waste in the future, you need to revise this plan. Nutrient levels for injecting waste and irrigating waste 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. Attached you will find information on proper sampling techniques, preparation, and transfer of waste samples to the lab for ananlysis. This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC 2H.0217 adopted by the Environmental Management Commission.

You should plan time and have appropriate equipment to apply the waste in a timely manner. The fallowing acreage will be needed for waste application based on the crop to be grown, soil type and suface application.

Acres show in each of the preceeding tables are considered to be the usable acres excluding required buffers, filter 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 fields fisted may, and most likely will be, more than the acres shown in the tables. NOTE: The Waste Utilization Plan must contain provisions for periodic land application of sludge at agronomic rates. The sludge will be nurturient rich and will require precautionary measures to prevent over application of nutrients or other elements. Your production facility will produce approximately 486.4 pounds of plant available nitrogen (PAN) per year in the sludge that will need to be removed on a periodic basis. This figure is PAN when broadcasting the sludge. Please be aware that additional acres of land, as well special equipment, may be needed when you remove this sludge. See the attached map showing the fields to be used for the utilization of waste water. 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. Your facility is designed for 180 days of temporary storage and the temporary storage must be removed on the average of once every 5.92 months. In no instance should the volume of waste being stored in your structure be within 1.58 feet of the top of the dike. If surface irrigation is the method of land application for this plan, it is the responsiblity of the producer and irrigation designer to ensure that an irrigation system is installed to properly irrigate the acres shown in Tables 1 and 2. Failure to apply the recommended rates and amounts of Nitrogen shown in the tables may make this plan invalid.

Page 4 NARRATIVE OF OPERATION This WUP was amended in the month of August due to the growers adding additional land to this WUP and removing pulls. Fields 1,2,3,and 4 pulls 1 thru 16 were removed and New Pulls A,B,C,D,E,F, and G were added. Additional land was cleared with a non-wetland Determination was approved with Field 7 Tract 72207. All new pulls will be sprigged with coastal bermuda hay and overseeded.A new wettable determination was approved by Jim Lynch(Certified Irrigation Designer) all all information was sent to Raleigh. This WUP was amended to reflect on 4111/18 to reflect the purchase of farm by Shawn Mitchell. All information was provided by Grower and from last updated WUP Page 5 PLANS & SPECIFICATIONS 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. Illegal discharges are subject to assessment of civil penalties of$10,000 per day by the Division of Water Quality for every day the discharge continues. 2. The Field Office must have documentation in the design folder that the producer either owns or has long term access to adequate land to properly dispose of waste. If the producer does not own adequate land to properly dispose of waste, he shall provide NRCS with a copy of a written agreement with a landowner who is within a reasonable proximity, allowing him/her the use of the land for waste application for the life expectancy of the production facility. 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, climate conditions, and level of management, unless there are regulations that restrict the rate of application for other nutrients. 4. Animal waste may be applied to land that has a Resource Management System (RMS) or an Alternative Conservation System (ACS). If an ACS is used the soil loss shall be no greater than 10 tons per acre per year and appropriate filter strips will be used where runoff leaves the field. These filter strips will be in addition to"Buffers" required by DEM. (See FOTG Stantard 393 - Filter Strips and Standard 390 Interim Riparian Forest Buffers). 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" in the NRCS Technical Reference - Environment file 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 conditions conducive to odor or flies and to provide uniformity of application. 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. 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 a crop on bare soil. 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 Page 6 and from any perennial stream or river(other that 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) 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 landownwer. 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 croplands provided they have been approved as a land application site by a "technical specialist". Animal waste should not be applied on grassed waterways that discharge directly into water courses, except when applied at agronomic rates and the application 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. *17. A protective cover of appropriate vegetation will be established on all disturbed areas (lagoon embankments, berms, pipe runs, etc.). if needed, special vegetation shall be provided for these areas and 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. Lagoon berms and structures should be inspected regularly for evidence of erosion, leakage or discharge. *1 B. 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 as a preemergence with no other 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 fpr 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 element. Zinc and copper levels in the soils shall be monitored and alternative crop sites pp . usted for shall be used when these metals approach excessive levels. pH shall be adjusted optimum crop production amd maintained. Soil and waste analysis records shall be kept for five (5) years. Poultry dry waste application records shall be maintained for three (3) years. Waste application records for all other waste shall be maintained for five (5) years. 23. Dead animals will be disposed of in a manner that meets North Carolina Department of Page 7 NAME OF FARM: Rose Brothers OWNER 1 MANAGER AGREEMENT } I (we) understand and will follow and implement the specifications and the operation and maintenance precedures estalished in the approved animal waste utilization plan for the farm named above. l (we) know that any expansion to the existing design capacity of the waste treatment and/or storage system or construction of new facilities will require a new utilization plan-and a new certification to be submitted to DEM before the new animals are stocked. 1 (we) understand that I must own or have acces to equipment, primarily irrigation equipment, to land apply the animal waste described in this waste utilization plan.

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, roats, • 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 of 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 constructed 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 1.8 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. 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 pattern 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 typical 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 the 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. SHEET 1 OF 2 OPERATION AND MAINTENANCE PLAN ------------------------------ This lagoon is designed for waste treatment (permanent storage) and �. 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 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 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 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 49.3 as marked-by permanent marker. Stop pump- out when the fluid level reaches elevation 47.2 . This temporary storage, less 25 yr- 24 hr storm, contains 38027 cubic feet or 284443 gallons. r f SHEET 2 OF 2 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 details. 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. 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. i SEEDING SPECIFICATIONS ---------------------- AREA TO BE SEEDED: 2.0 ACRES USE THE SEED MIXTURE INDICATED AS FOLLOWS: 0.0 LBS.

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 after 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 irrtakes or crystallization of mainlines wiil 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 croiled flow and determine the application rate. Rain gauges work best because they already have a graduated scale from which to read the app acation a jars.ount othout havft r anything with a erfoorm form additional calculations. However, pans, plastic 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 show 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 c:ancem. You should contact your Irrigation dealer or technical specialist for assistance. Reprinted for Cedr#oathn Tralntng for Operations of Anima{Waste Management Systems Manuaf l 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 bermudograss) or when there are extended rainy spells such as a thunderstorm season in the summertime. This means that at the first sign of plairi growth in the later winter i 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 mathfaln 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 malntenance 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 Solis test, but in the event that it is not practical to obtaln 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.weather should be done at least once a year and possibly twice in years conditions are favorable for heavy vegetative growth, NOTE: it'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 frosting the waste, during the initial Of the Lagoon and least montnance thhly and after major rainfall anctions of the entire lagoon should storm eventse items to be checked shoo d inckWe, as a minimum,the following: Waste InINt Pip",Recycling Pipes,and Ovwflow Pipes—took 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. boating 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 finer 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 skkmll, 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 aU 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 follovAng 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 hank 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 B.O. 7. A dark color, hack of bubbling, and excessive odor signals inadequate biological activity. Consultation with a technical speciailst is recommended if these conditions occur for prolonged periods, especially during the warn 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 tiaras 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. • lAnimize 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 I 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 and 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 past 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 vaiues 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 alteration 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 finer 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 sits. Extra precaution shouid be used to observe the wind direction and other conditions which could increase the concem 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 am a safety risk Failure to inspect and,maintain the dam. Excess surface water flowing into the lagoon. Uner 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. 7 ZZ�' �'_5 e r.j EMERGENCY ACTION PLAN PHONE NUMBERS Division of Water Resources (DWR) Emergency Management System(EMS) Soil and Water Conservation District (SWCD) ;/--yO Natural Resources Conservation Service (NRCS) 9/d ::;;If This plan will be implemented in the event that wastes from your operation are Ieaking, 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: 1) Add soil to berm to increase elevation of dam. 2) Pump wastes to fields at an acceptable rate. 3) Stop all flows to the lagoon immediately. 4) Call a pumping contractor. 5) Make sure no surface water is entering lagoon. b. Runoff from waste application field-actions include: 1) Immediately stop waste application. 2) Create a temporary diversion to contain waste. 3) Incorporate waste to reduce runoff. 4) Evaluate and eliminate the reason(s) that caused the runoff. 5) Evaluate the application rates for the fields where runoff occurred. c. Leakage from the waste pipes and sprinklers-action include: 1) Stop recycle pump. 2) Stop irrigation pump. 3) Close valves to eliminate further discharge. 4) Repair all leaks prior to restarting pumps.
