Any method which, in the professional opinioniof the State Veterinarian, would -make possible the salvage of part of a dead animal's value without endangering human or animal health. (Written approval by the State Veterinarian must be attached). Mass Mortality Plan Mass mortality plans are required for farms covered by an NPIDES permit. These plans are also recommended for all animal operations. This plan outlines farm -specific mortality man- agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup- ports a variety of emergency mortality disposal options; contact.the Division for guidance. • A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated when numbers of dead animals exceed normal mortality rates as specified by the State Veterinarian. • Burial must beidone in accordance with NC General Statutes and NCDA&CS Veterinary Division regulations and guidance. • Mass burial sites are subject to additional permit conditions (refer to facility's animal waste management system permit). • In the event of imminent threat of a disease emergency, the State Veterinarian may enact additional temporary procedures or measures for disposal according to G.S. 106-399.4. e a r� r1Ma ager Date Signature of Technical Specialist Date A ROBESON Date: 08/19/94 DistancP- 7 r- owner). 1700.0 feet 1.

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 mini mum liquid level as long as the weather and waste utilization plan will allow it. �Vaiting until the lagoon has reached its maximum storage ca acity 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 embankmenIt 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 irowth. NOTE: If vegetation is controlled by spraying, the herbicide must not be ed the lagoon water. Such allow to enter the waste. chemicals could harm the bacteria in the lagoon that are treating 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 - I. 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: I . settlement, cracking or "jug" holes 2. side slope stability ---'slumps or bulges 3. wet of 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. I . 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 f�ilure. 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 in$PW your diversion system for the following, I , adcquatc vegetation 2. diversion capacity 3. ridge berm height Identified problems should be Corrected promptly. It is advisable to inspect your system during or Immediately f011owing 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 pumpini). 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 rainfa for this to work). Knowing this should help in Planning irrigation applications and storage, If your lagoon rises excessively you may have an inflow problem from a surface water diversion or there may be seep' lagoon from the surrounding land. age into the 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 tQ erode lining or bank slopes. 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 liquid volume, This seeding should Occour at least two weeks prio 00 working swine lagoon in the amount of 0.25 percent of the full lag n addition of wastewater. r to the 6. Maintain a periodic check on the lagoon liquid PH, If the PH falls below 7.0, add agricultural lime at the rate of 1 pound per 1000 cubic feet of lagoon liquid volume until the PH rises above 7,0, Optimum lagoon liquid PH is between 7.5 and 8.0. 7. A dark Color, lack of bubbling, and excessive odor signals inadequate biological activity, Consultation with a technical specialist is recommended if these conditions occur for Prolonged periods, especially during the warm season. Loading: The more frequently and regularly that wastewater is added to a lagoon, the better the lRgOOn will function. Flush systems that wash waste into the lagoon several times daily arc OPtimum for treatment, Pit recharge systems, in which one or mor buildings are drai and recharged each day, also work well. e ned Practice Watef (-'Onseryadon---minimize building water usage and spillage from leaking waterers, broken Pipes and Washdown through Proper maintenance and water conservation.

This Management: will reduce the amou�t Of solids entering the lagoon Maintain lagoon liquid level between the Permanent Storage le el nd the full temporary storage level, v a Placevisible markers or stakes on the lagoon bank to show the minimum liquid level and the maximum liquid lever (Figure 2-1). Stan irrigating at the earliest Possible date in the spring based on nutrient requirements and so" moisture so that temporary storage will be maximized for the summer thunderstorm season. Similarly, irrigate in the late summer/early fan 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 faz 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 Cow 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: P,ate 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. Ugoon 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 vaJue. The application of sludge will increase the amount of odor at the waste application site. Extra precaution should be us,ed to observe the wind direction and Other conditions which could increase the concern of neighbors, Possible Causm Of IA900n 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 t)lacement of a pipe in the dam without Proper design and construction. lagoon design befoje placing any pipes in dams.) (CO�sult an expert in 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.
