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. 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. Soil types are important as they have different infiltration rates, leaching potentials, cation exchange capacities, and available water holding capacities. Normally waste shall not be applied to land eroding at greater than 5 tons per acre per year. With special precautions, waste may be applied to land eroding at up to 10 tons 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 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. 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 analysis. This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC 2H.0217 adopted by the Environmental Management Commission.

PAN produced is based on 3 years of actual pumpi on Page 4 REQUIRED SPECIFICATIONS 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. 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 waste, he/she shall provide a copy of an agreement with a landowner who is within a reasonable proximity, allowing him/her the use of the land for waste application. It is the responsibility of the owner of the facility to secure an update of the Waste Utilization Plan when there is a change in the operation, increase in the number of animals, method of utilization, or available land. 3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic crop yields based on soil type, available moisture, historical data, climatic conditions, and level of management, unless there are regulations that restrict the rate of application for other nutrients. 4 Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste may be applied to land that is eroding at 5 or more tons, but less than 10 tons per acre per year providing grass filter strips are installed where runoff leaves the field. (See FOTG Standard 393 - Filter Strip). 5 Odom can be reduced by injecting the waste or disking after waste application. Waste should not be applied when there is danger of drift from the irrigation field. 6 When animal waste is to be applied on acres subject to flooding, it will be soil incorporated on conventionally tilled cropland. When applied to conservation tilled crops or grassland, the waste may be broadcast provided the application does not occur during a season prone to flooding. (See "Weather and Climate in North Carolina" for guidance.) 7 Liquid waste shall be applied at rates not to exceed the soil infiltration rate 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 pending should occur in order to control odor or flies. 8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the surface is frozen. Page 5 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 Waste nutrients shall not be applied in fall or winter for spring planted crops on soils with a high potential for leaching. Waste nutrient loading rates on these soils should be held to a minimum and a suitable winter cover crop planted to take up released nutrients. Waste shall not be applied more than 30 days prior to planting of the crop or forages breaking dormancy. 11 Any new swine facility sited on or after October 1, 1995 shall comply with the following: The outer perimeter of the land area onto which waste is applied from a lagoon that is a component of a swine farm shall be at least 50 feet from any residential property boundary and from any perennial stream or river (other than an irrigation ditch or canal. Animal waste other than swine waste from facilities sited on or after October 1, 1995), shall not be applied closer than 25 feet to perennial waters. (See Standard 393 - Filter Strips). 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 wetlands provided they 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 courses 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. W.... �WASSEJUT,ILIZAT�ON ,P_LAN, 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 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 element. Zinc and copper levels in the soil shall be monitored and alternative crop sites shall be used when these metal approach excessive levels. pH shall be adjusted for optimum crop production and maintained. Soil and waste analysis records shall be kept for five 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 animalswill be disposed of in a manner that meets North Carolina regulations.

ODOR BEST MANAGEMENT PLAN Triad Farms #1&2 August 23, 2001 As required by NCAC Title 15A, Chapter 2, Subchapter 2D .1800, the following was prepared as outlined by NCAC 2D .1803 to serve as a Best Management Plan for the Triad Sow Farm. Prepared by Triad Farms and Kraig Westerbeek John Salmon —Vice President Technical Specialist, Murpby-Brown PO Box 789 PO Box 759 Wallace, NC 28466 Rose Hill, NC 28458 (910) 285 7200 (910) 289 2111 Triad #1&2 is owned and operated by Triad Farms, and is located at 470 Rogers Mill Rd, Magnolia,NC. This farm has a capacity of 7200 sows and their offspring to weaning, 2000 head of finishing, and 800 head of nursery space. There are 12 flush type buildings served by two anaerobic lagoons totalling approximately 11 acres in size. The waste generated from this facility is land applied to approximately 150 acres of surrounding mop land, as outlined in the certified animal waste management plan for this facility. This farm was originally certified and stocked in 1994. All applicable setback requirements in place at the time of construction were followed. Potential odor sources for this facility include, but are not limited to, buildings, manure flushing systems, anaerobic lagoon, land application of waste, feed storage areas, and mortality disposal. To address this potential, this farm follows an odor control checklist as required by its General Permit issued by DENR's Division of Water Quality. This plan outlines how each of these areas are to be managed, and is attached for reference, Attached to this plan is a map of the facility and surrounding land. These buildings are natural vent type structures, therefore, there are no forced air directions shown. Residences, etc... are marked to the best of our ability. The owner/ manager of this farm has implemented the Odor Control Checklist and additional measures described above. The requirements of this checklist are used it as a reference tool for odor issues.

Water TabieL.- �2-00 Ft - OPERATION & MAINTENANCE PLAN �roPer 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 receivin crop is dormant (such as wintertime for bermudagriss) or when there are extendefrainy 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 Cow 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 a�plied shZd be based on a soils test, but in the event that it is not practical to obtain a soils test each year, the la oon embankment and surrounding areas should be fertilized with 8M pounds per acre of 10- 10. 10, or equivalent. Brush arid 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 hwYy vegetative growth, NOTF: 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! I . undesirable vegetative growth 2. floating or lodged debris Embankment --- look for: I . settlement, cracking, of "jug" holes 2. side slope stabitiry--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 i�to 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 --- cheek for proper operation of. I Fe�ycling 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 spaxe parts or pumps. Surface water diversion features we designed to carry all surface drainage waters (such as rainfall runoff, roof drainage, gutter Outlets, and parking lot rumoff) 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: I . 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 technicaJ 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 purnpin ?). This will give you an idea of how much your lagoon level will rise with a certain rain all amount (YOU must also be recording your rainfall for this to work). Knowing this should help in �Ianning irrigation applications and storage, If your lagoon rises excessively, you may ave an 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 I uid volume. This seeding should occour at least two weeks prior to the '2 a dition 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.u. 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 Umes 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--mirdmize building water usage and spillage from leaking waterers, broken pipes and washdown through proper maintenance and water conservation. Minimize feed wastage and spillage b� keeping feeders adjusted, This will reduce the a -mount of solids entering the lagoon Managamenti 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 ssible date in the spring based on nutrient requirements and soirloisture 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 I 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 rills 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 = be reduced by: proper lagoon sizing, mechanical solids separation of flushed waste, gra�itY 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 slud e and lagoon liquid with a chopper -agitator impeller pump througg 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; ump into liquid sludge applicator; haul and spread onto cropland or forage?and; 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, T�e application of the sludge to fields will be limited by these nutrients as well as any revious 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 lag n liner remains intact. If You See sin . oo I 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. e re ed h a cO uo It ru and heavy metal content an v ece om e n a in ' "g e' P'O'P'o S ' u" To 'r t ' ' 'a ft vB e th ho d lal ap d ho Otal an u an of t 2ly e 0 rp) a ed M ce 't0h cphar sp 0 to I w w h th as th t to r u e Ice f d ' u e u indl b ' a I o1prost, d In 0 m Is ' y r sl n if e s u g p to r o 0 0 ed at I d eisa Piled Jelds with very high soll_test phos hores, it should be appl only at rates equal the crop rem oval of ph sp horus A s wJtPh other w stes , always I ave your gm slu to e analyzed for t utrie 0 t va� ue a h Is n dg i s n n 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 mpture 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.
