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 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 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
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.

WASTE UTILIZATION PLAN
Amount of Waste Produced Per Year (gallons, ft, tons, etc.)
11,006 animals X 766 (tons) waste/animal/year = 8,430,596.0 (amt.) waste/year.
Amount of Plant Available Nitrogen (PAN) Produced Per Year
11,006 animals X 1_8 lbs. PAN/animal/year =
*20% reduction for 2nd stage lagoon for 5,033 animals
19,810.8 lbs. PAN/year.
1811
17,999.80 Ibs/yr
Applying the above amount of waste is a big job. You should plan time and have
appropriate equipment to apply the waste in a timely manner.
The following acreage will be needed for waste application based on the crop to be grown
and surface application:
See Page 2a For Acres Owned By Producer
'This N is from animal waste only. If nutrients from other sources such as commercial
fertilizer are applied, they must be accounted for. N must be based on realistic yield
expectation.
NOTE: The applicator is cautioned that P and K may be over applied while meeting the N
requirements. Beginning in 1996 the Coastal Zone Management Act will require farmers in
some eastern counties of North Carolina to have a nutrient management plan that addresses
all nutrients. This plan only addresses Nitrogen.

THIS TABLE IS NOT NEEDED IF WASTE IS NOT BEING APPLIED BY IRRIGATION,
HOWEVER A SIMILAR TABLE WILL BE NEEDED FOR DRY LITTER OR SLURRY.
** 7 Lagoons**
Your facility is designed for 180 days of temporary storage and the temporary
storage must be removed on the average of once every 6 Months. In no
instance should the volume of waste being stored in your structure exceed
Elevation *see lagoon staff gauges.
Call the local Natural Resources Conservation Service (formerly Soil
Conservation Service) or Soil and Water Conservation District office after you
receive the waste analysis report for assistance in determining the amount per
acre to apply and the proper application rate prior to applying the waste.
Narrative of operation:
This NUP reflects wettable acres for reels and aerways.
This farm uses an aerwav system and hard hose traveller system for irrigation.
The method of nutrient removal is through having, grazing and row crops.

WASTE UTILIZATION PLAN
REQUIRED 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.
2 There must be documentation in the design folder that the producer either owns or
has and agreement for use of adequate land on which 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 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" 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 or flies.
8 Animal waste shall not be applied to saturated soils, during rainfall events, or when
the surface is frozen.

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
(continued)
9 Animal waste shall be applied on actively growing crops in such a manner that the
crop is not covered with waste to a depth that would inhibit growth. The potential
for salt damage from animal waste should also be considered.
10 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 no 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 wetlands provided they have been approved as a land application site by
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 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 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.
NUP Page 6

WASTE UTILIZATION PLAN
18 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.
19 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 is should only be applied preplant with no further applications
of animal waste during the crop season.
20 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 markers. A marker will be
required to mark the maximum storage volume for waste storage ponds.
21 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 shall be used when these metals 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.
22 Dead animals will be disposed of in a manner that meets North Carolina
regulations.

Mortality Management Methods
Indicate which method(s) will be implemented.
When selecting multiple methods indicate a primary versus secondary option.
Methods other than those listed must be approved by the State Veterinarian.
P imary Secondary Routine Mortality
n Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal
death. The burial must be at least 300 feet from any flowing stream or public body of water
(G.S.106-403). The bottom of the burial pit should be at least one foot above the seasonal
high water table. Attach burial location map and plan.
n n Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC
13B .0200.
® O Rendering at a rendering plant licensed under G.S. 106-168.7.
Complete incineration according to 02 NCAC 52C .0102.
n n A composting system approved and permitted by the NC Department of Agriculture & Con-
sumer Services Veterinary Division (attach copy of permit). If compost is distributed off -farm,
additional requirements must be met and a permit is required from NC DEQ.
n n In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture & Consumer Services (G.S. 106-549.70),
n n Any method which, in the professional opinion of 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).
InMass Mortality Plan
Mass mortality plans are required for farms covered by an NPDES permit. These plans are
also recommended for all animal operations. This plan outlines farm -specific mortality man-
agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup-
ports a variety of emergency mortality disposal options; contact the Division for guidance.
• A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated
when numbers of dead animals exceed normal mortality rates as specified by the State
Veterinarian.
• Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary
Division regulations and guidance.
• Mass burial sites are subject to additional permit conditions (refer to facility's animal
waste management system permit).
• In the event of imminent threat of a disease emergency, the State Veterinarian may enact
additional temporary procedures or measures for disposal according to G.S. 106-399.4.

OPERATION & MAINTENANCE PLAN
Proper lagoon management should be a year-round priority. It is especially important to manage
levels so that you do not have problems during extended rainy and wet periods.
Maximum storage capacity should be available in the lagoon for periods when the receiving crop is
dormant (such as wintertime for bermudagrass) or when there are extended rainy spells such as a
thunderstorm season in the summertime. This means that at the first sign of plant growth in the
later winter / early spring, irrigation according to a farm waste management plan should be done
whenever the land in dry enough to receive lagoon liquid. This will make storage space available in
the lagoon for future wet periods. In the late summer / early fall the lagoon should be pumped down
to the low marker (see Figure 2-1) to allow for winter storage. Every effort should be made to
maintain the lagoon close to the minimum liquid level as long as the weather and waste utilization
plan will allow it.
Waiting until the lagoon has reached its maximum storage capacity before starting to irrigated does
not leave room for storing excess water during extended wet periods. Overflow from the lagoon for
any reason except a 25-year, 24-hour storm is a violation of state law and subject to penalty action.
The'routine maintenance of a lagoon involves the following:
Maintenance of a vegetative cover for the dam. Fescue or common bermudagrass
are the most common vegetative covers. The vegetation should be fertilized each
year, if needed, to maintain a vigorous stand. The amount of fertilized applied should
be based on a soils test, but in the event that it is not practical to obtain a soils test
each year, the lagoon embankment and surrounding areas should be fertilized with
800 pounds per acre of 10-10-10, or equivalent.
Brush and trees on the embankment must be controlled. This may be done by
mowing, spraying, grazing, chopping, or a combination of these practices. This
should be done at least once a year and possibly twice in years that weather
conditions are favorable for heavy vegetative growth.
NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter the lagoon
water. Such chemicals could harm the bacteria in the lagoon that are treating the waste.
Maintenance inspections of the entire lagoon should be made during the initial filling of the lagoon
and at least monthly and after major rainfall and storm events. Items to be checked should include,
as a minimum, the following:
Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes -- look for:
1. separation of joints
2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes
M00202041513
2

Lagoon surface -- look for:
1. undesirable vegetative growth
2. floating or lodged debris
Embankment -- look for:
1. settlement, cracking, or "jug" holes
2. side slope stability -- slumps or bulges
3. wet or damp areas on the back slope
4. erosion due to lack or vegetation or as a result of wave action
5. rodent damage
Larger lagoons may be subject to liner damage due to wave action caused by strong
winds. These waves can erode the lagoon sidewalls, thereby weakening the lagoon dam.
A good stand of vegetation will reduce the potential damage caused by wave action. If
wave action causes serious damage to a lagoon sidewall, baffles in the lagoon may be
used to reduce the wave impacts.
Any of these features could lead to erosion and weakening of the dam. If your lagoon has
any of these features, you should call an appropriate expert familiar with design and
construction of waste lagoons. You may need to provide a temporary fix if there is a
threat of a waste discharge. However, a permanent solution should be reviewed by the
technical expert. Any digging into a lagoon dam with heavy equipment is a serious
undertaking with potentially serious consequences and should not be conducted unless
recommended by an appropriate technical expert.
Transfer Pumps -- check for proper operation of:
1. recycling pumps
2. irrigation pumps
Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding
noise, or a large amount of vibration, may indicate that the pump is in need of repair or
replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that
you are not completely "surprised" by equipment failure. You should perform your
pumping system maintenance at a time when your lagoon is at its low level. This will
allow some safety time should major repairs be required. Having a nearly full lagoon is
not the time to think about switching, repairing, or borrowing pumps. Probably, if your
lagoon is full, your neighbor's lagoon is full also. You should consider maintaining an
inventory of spare parts or pumps.
• Surface water diversion features are designed to carry all surface drainage
waters (such as rainfall runoff, roof drainage, gutter outlets, and parking lot
runoff) away from your lagoon and other waste treatment or storage
structures. The only water that should be coming from your lagoon is that
which comes from your flushing (washing) system pipes and the rainfall that
hits the lagoon directly. You should inspect your diversion system for the
following:
1. adequate vegetation
2. diversion capacity
3. ridge berm height

Identified problems should be corrected promptly. It is advisable to inspect your system
during or immediately following a heavy rain. If technical assistance is needed to
determine proper solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then
record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will
give you an idea of how much your lagoon level will rise with a certain rainfall amount
(you must also be recording your rainfall for this to work). Knowing this should help in
planning irrigation applications and storage. If your lagoon rises excessively, you may
have an overflow problem from a surface water diversion or there may be seepage into
the lagoon from the surrounding land.
Lagoon Operation
Startup:
1. Immediately after construction establish a complete sod cover on bare soil
surfaces to avoid erosion.
2. Fill new lagoon design treatment volume at least half full of water before waste
loading begins, taking care not to erode lining or bank slopes.
3. Drainpipes into the lagoon should have a flexible pipe extender on the end of the
pipe to discharge near the bottom of the lagoon during initial filling or another
means of slowing the incoming water to avoid erosion of the lining.
4. When possible, begin loading new lagoons in the spring to maximize bacterial
establishment (due to warmer weather).
5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon liquid
volume. This seeding should occur at least two weeks prior to the addition of
wastewater.
6. Maintain a periodic check on the lagoon liquid pH. If the pH falls below 7.0, add
agricultural lime at the rate of 1 pound per 1000 cubic feet of lagoon liquid volume
until the pH rises above 7.0. Optimum lagoon liquid pH is between 7.5 and 8.0.
7. A dark color, lack of bubbling, and excessive odor signals inadequate biological
activity. Consultation with a technical specialist is recommended if these
conditions occur for prolonged periods, especially during the warm season.
Loading:
The more frequently and regularly that wastewater is added to a lagoon, the better the
lagoon will function. Flush systems that wash waste into the lagoon several times daily
are optimum for treatment. Pit recharge systems, in which one or more buildings are
drained and recharged each day, also work well.

• Practice water conservation --- minimize building water usage and spillage from
leaking waterers, broken pipes and washdown through proper maintenance and water
conservation.
• Minimize feed wastage and spillage by keeping feeders adjusted. This will reduce the
amount of solids entering the lagoon.
Management:
• Maintain lagoon liquid level between the permanent storage level and the full
temporary storage level.
• Place visible markers or stakes on the lagoon bank to show the minimum liquid level
and the maximum liquid level. (Figure 2-1).
• Start irrigating at the earliest possible date in the spring based on nutrient
requirements and soil moisture so that temporary storage will be maximized for the
'summer thunderstorm season. Similarly, irrigate in the late summer / early fall to
provide maximum lagoon storage for the winter.
• The lagoon liquid level should never be closer than 1 foot to the lowest point of the
dam or embankment.
• Don not pump the lagoon liquid level lower than the permanent storage level unless
you are removing sludge.
• Locate float pump intakes approximately 18 inches underneath the liquid surface and
as far away from the drainpipe inlets as possible.
• Prevent additions of bedding materials, long-stemmed forage or vegetation, molded
feed, plastic syringes, or other foreign materials into the lagoon.
• Frequently remove solids from catch basins at end of confinement houses or
wherever they are installed.
• Maintain strict vegetation, rodent, and varmint control near lagoon edges.
• Do not allow trees or large bushes to grow on lagoon dam or embankment.
• Remove sludge from the lagoon either when the sludge storage capacity is full or
before it fills 50 percent of the permanent storage volume.
• If animal production is to be terminated, the owner is responsible for obtaining and
implementing a closure plan to eliminate the possibility of a pollutant discharge.
Sludge Removal:
Rate of lagoon sludge buildup can be reduced by:
5
MO0202041516

• 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 you? lagoon water. The sludge will contain different
nutrient and metal values from the liquid. The application of the sludge to fields will be
limited by these nutrients as well as any previous waste applications to that field and crop
requirement. Waste application rates will be discussed in detail in Chapter 3.
When removing sludge, you must also pay attention to the liner to prevent damage.
Close attention by the pumper or drag -line operator will ensure that the lagoon liner
remains intact. If you see soil material or the. synthetic liner material being disturbed, you
should stop the activity immediately and not resume until you are sure that the sludge can
be removed without liner injury. If the liner is damaged it must be repaired as soon as
possible.
Sludge removed from the lagoon has a much higher phosphorus and heavy metal content
than liquid. Because of this it should probably be applied to land with low phosphorus and
metal levels, as indicated by a soil test, and incorporated to reduce the chance of erosion.
Note that if the sludge is applied to fields with very high soil -test phosphors, it should be
applied only at rates equal to the crop removal of phosphorus. As with other wastes,
always have your lagoon sludge analyzed for its nutrient value.
The application of sludge will increase the amount of odor at the waste application site.
Extra precaution should be used to observe the wind direction and other conditions which
could increase the concern of neighbors.

Possible Causes of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure.
Types of failures include leakage through the bottom or sides, overtopping, and breach of
the dam. Assuming proper design and construction, the owner has the responsibility for
ensuring structure safety. Items which may lead to lagoon failures include:
• Modification of the lagoon structure -- an example is the placement of a pipe in the dam
without proper design and construction. (Consult an expert in lagoon design before
placing any pipes in dams.)
• Lagoon liquid levels -- high levels are a safety risk.
• Failure to inspect and maintain the dam.
• Excess surface water flowing into the lagoon.
• Liner integrity -- protect from inlet pipe scouring, damage during sludge removal, or
rupture from lowering lagoon liquid level below groundwater table.
NOTE: If lagoon water is allowed to overtop the dam, the moving water will soon cause
gullies to form in the dam. Once this damage starts, it can quickly cause a large
discharge of wastewater and possible dam failure.
