These estimates are based on average nitrogen concentrations for each source,the number of animals in the facility and the plant available nitrogen application rates shown in the second column. Lagoon sludge contains nutrients and organic matter remaining after treatment and application of the effluent. At clean out,this material must be utilized for crop production and applied at agronomic rates. In most cases,the priority nutrient is nitrogen but Other nutrients including phosphorous,copper and zinc can also be limiting. Since nutrient levels are generally very high, application of sludge must be carefully applied. Sites must first be evaluated for their suitability-for sludge application. Ideally,effluent spray-fields should not be used for sludge application. If this is not possible,care should be taken not to load effluent application fields with high amounts of copper and zinc so that additional effluent cannot be applied. On sites vulnerable to surface water moving to streams and lakes,phosphorous is a concern. Soils containing very high phosphorous levels may also be a concern.

Available storage capacity is calculated as the design storage capacity in days minus the number of days of net storage volume accumulated The start date is a value entered by the user and is defined as the date prior to applying nutrients to the first crop in the plan at which storage volume in the lagoon or holding pond is equal to zero. Available storage capacity should be greater than or equal to zero and less than or equal to the design storage capacity of the facility. Ifthe available storage capacity is greater than the design storage capacity,this indicates that the plan calls for the application of nutrients that have not yet accumulated. If available storage capacity is negative,the estimated volume of accumulated waste exceeds the design storage volume of the structure. Either of these situations indicates that the planned application interval in the waste utilization plan is inconsistent with the structure's temporary storage capacity.

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 that 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 Management Plan when there is a change in the operation, increase in the number of animals,method of application, receiving 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 by 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. -------------------------------_----------------------------------------------------720298 Database Version 3.0 Date Printed:9/23/2003 Specification Page 1 8. Animal waste shall not be applied to saturated soils, during rainfall events,or when the soil surface is frozen. 9. Animal waste shall be applied on actively growing crops in such a manner that the crop is not covered with waste to a depth that would inhibit growth.The potential for salt damage from animal waste should also be considered. 10. 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 that 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 a 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. ------------------------ ------ - ______ _______________ _______ 720298 Database Version 3.0 Date Printed: 9/23/2003 SDecification Page 2 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. V 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 soils 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 five (5) years. 23. Dead animals will be disposed of in a manner that meets North Carolina regulations. -------------------------------- --------------------------------- --- 720298 Database Version 3.0 Date Printed: 9/23/2003 Specification Page 3 Crop Notes The following crop note applies to field(s): PI,P2,P3,P4,P5,P6,P7,P8,P9 Small Grain: CP, Mineral Soil,medium leachable In the Coastal Plain,oats and barley should be planted from October 15-October 30; and rye from October 15 November 20.

In the Coastal Plain,hybrid bermudagrass sprigs can be planted Mar. 1 to Mar. 31. Cover sprigs 1"to 3" deep (1.5"optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and wind. For Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2'to 3' in the row. Generally a rate of 30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5'to 2' rows spaced 1'to 1.5'in row. For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime,phosphorus,potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 100 lblac N in the establishment year in split applications in April and July. For established stands apply 180 to 240 lb/ac N annually in split applications, usually in April and following the first and second hay cuts. Reduce N rates by 25%for grazing.

NOTE: SEE ATTACHED WASTE UTILIZATION PLAN COMMENTS: OPERATION & MAINTENANCE PLAN Proper lagoon liquid 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 the thunderstorm season in the summertime. This means that at the first signs of plant growth in the later winter/early spring, irrigation according to a farm waste management plan should be done whenever the land is 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 irrigate 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 fertilizer 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 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 of 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 or 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 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 a.n inflow 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 occour 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 Iime 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. 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 lever (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. Do not pump the lagoon liquid level lower that 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: 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 phosphores, 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. 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 Iagoon 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. �-� �� � �� v AME: Steve Grady DDRESS: MMt , Olive , N. C.

DESIGNED APPROVED BY: DATE: . NOTE: SEE ATTACHED WASTE UTILIZATION PLAN COMMENTS: OPERATION AND MAINTENANCE FLAN SHEET 1 OF c ------------------------------ 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 E5 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 36. 3 as marked by permanent marker. Stop pump-- out when the fluid level reaches elevation 34. 3 . This temporary storage, less 25 yr— 24 tit, storm, contains 52957 cubic feet or 470918 gallons. SHEET E OF 2 4. The recommended maximLim amount one ( 1 ) to apply per it^r^igat ion is 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 oil 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 E00 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. �-� �� � �� v AME: Steve Grady DDRESS: MMt , Olive , N.
