Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface water 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:
1. 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.
2. Soil types are important as they have different infiltration rates, leaching potentials,
cation exchange capacities, and available water holding capacities.
3. Normally waste shall be applied to land eroding at less than 5 tons per acre per
year. Waste may be applied to land eroding at 5 or more tons per acre annually, but
less than 10 tons per acre per year providing that adequate filter strips are established.
4. 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 DWQ regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor
Page: 1

problems.
6. To maximize the value of the nutrients for crop production and to reduce the potential
for pollution, the waste should be applied to a growing crop or applied not more than
30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or
disking will conserve nutrients and reduce odor problems.
This plan is based on the waste application method shown above. If you choose to change
methods in the future, you need to revise this plan. Nutrient levels for different application
methods are not the same.
The estimated acres needed to apply the animal waste is based on typical nutrient content
for this type of facility. In some cases you may want to have plant analysis made, which could
allow additional waste to be applied. Provisions shall be made for the area receiving waste to
be flexible so as to accommodate changing waste analysis content and crop type. Lime must
be applied to maintain pH in the optimum range for specific crop production.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
2H .0217 adopted by the Environmental Management Commission.
AMOUNT OF WASTE PRODUCED PER YEAR ( gallons, ft3, tons, etc.):
2600 animals X
223 gal/animal/year = 578,890 gallons
AMOUNT OF PLANT AVAILABLE NITROGEN PRODUCED PER YEAR (Ibs):
2600 animals X 0.48 Ibs/animal/year = 1,248.00 Ibs
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,
soil type, and surface application.

*A negative number reflects the total Ibs of additional nitrogen needed to achieve yields on
acreage listed in chart. A positive number means additional acreage is required to utilize the
nitrogen produced by the farm.
NOTE:
This plan does not include commercial fertilizer. The farm should produce adequate plant
available nitrogen to satisfy the requirements of the crops listed above.
The applicator is cautioned that P and K may be over applied while meeting the N requirements.
In the future, regulations may require farmers in some parts of North Carolina to have a nutrient
management plan that addresses all nutrients. This plan only addresses nitrogen.
In interplanted fields ( i.e. small grain, etc, interseeded in bermuda), forage must be removed
through grazing, hay, and/or silage. Where grazing, plants should be grazed when they
reach a height of six to nine inches. Cattle should be removed when plants are grazed to a
height of four inches. In fields where small grain, etc, is to be removed for hay or silage, care
should be exercised not to let small grain reach maturity, especially late in the season (i.e.
April or May). Shading may result if small grain gets too high and this will definately interfere
with stand of bermudagrass. This loss of stand will result in reduced yields and Tess nitrogen
being utilized. Rather than cutting small grain for hay or silage just before heading as is
the normal situation, you are encouraged to cut the small grain earlier. You may want to
consider harvesting hay or silage two to three times during the season, depending on the
time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

If surface irrigation is the method of land application for this plan, it is the responsibility of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in the preceding table. Failure to apply the recommended rates and

WASTE UTILIZATION PLAN
RE UIRED 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 an agreement for use of adequate
land on which to properly apply the waste.

notvown a copyproperly dispose of waste, he/she shall
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.
9. Animal waste shall be applied on actively
growing
in such
a manner that the crop is not covered with waste tocaodepth that
would inhibit growth. The potential for salt damage from animal
waste should also be considered.

This plan will be implemented in the event that wastes from
your operation are leaking, overflowing, or running off
site.- You should not wait until wastes reach surface waters
or leave your property to consider that you have a problem.
You should make every effort to ensure that this does not
happen. This plan should be posted in an accessible
location for all emoloyees at the facility. The following
are some action items you should take.
1. Stop the release of wastes. Depending on the
situation, this may or may not be possible. Suggested
responses to some possible problems are listed below.
A. Lagoon overflow -possible solutions are:
a. Add soil to berm to increase elevation of dam.
b. Pump wastes to fields,at an acceptable rate.
c. Stop all flows to the lagoon immediately.
d. Call a pumping contractor.
e. Make sure no surface water is entering lagoon.
B: Runoff from waste application field -actions
include: -
a. Immediately stop waste application.
b. Create a temporary diversion to contain waste.
c. Incorporate waste to reduce runoff.
d. Evaluate and eliminate the reason(s) that
caused the runoff.
e. Evaluate the application rates for the fields
where runoff occurred.
•C: Leakage from the waste pipes and sprinklers -action
include:
a. Stop recycle pump.
b. Stop irrigation pump..
c.. Close valves to eliminate further discharge.

d. Repair all leaks prior to restarting pumps.
D: Leakage from flush systems, houses, solid
separators -action include:
a. Stop recycle pump.
b. Stop irrigation pump.
c. Make sure no siphon occurs.
d. Stop all flows in the house, flush systems, or
solid separators.
e. Repair all leaks prior to restarting pumps.
E: Leakage from base or sidewall of lagoon. Often
this is seepage as opposed to flowing leaks -
possible action:
a. Dig a small well or ditch to catch all seepage,
put in a submersible pump, and pump back to
lagoon.
b. If holes are caused by burrowing animals, trap
or remove animals and fill holes and compact
with a clay type soil.
c. Have a professional evaluate the condition of
the side walls and lagoon bottom as soon as
possible.
2. Assess the extent of the spill and note any obvious
damages.
a. Did the waste reach any surface waters?
b. Approximately how much was released and for what

(Written approval by the State Veterinarian must be attached).
Mass 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 bedone 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.

This lagoon .is designed for waste treatment with rninirnurn
odor- control. The time required for the planned level to be
reached may vary due_ to soil conditions., flushing
operations, and the amount of fresh water added to the
system. This lagoon does not have design storage for fresh
water. Once the effluent depth in lagoon is adequate for
recyclirrg flush, fresh water should not be used. Lagoon i s -
designed to store a 25 year storm rainfall event plus normal
rainfall in excess of evaporation.
Land application of waste water is recognized as an
acceptable method .Of disposal. Care creeds to be taken when
applying waste tci prevent damage to crops or runoff from the
field. Rate of application should not exceed 0.5 inches per
hour. Waste shou i d be applied according to so i 1 test and
waste analysis on actively growing (grass) or immediately
prior to planting (corn).
The following items are to be carried out:
1. Begin pump -out of the lagoon when fluid level reaches
the bottom of the outlet pipes. Lagoon is designed
for 6 month pumping cycle.
._. Stop purnp-out before fluid depth is less than 6. feet
deep (this prevents the loss of favorable bacteria) .
3. It is strongly recommended that the treatment lagoon
be precharged to 1/2 its capacity to prevent excessive
odors during startup. Prechar-g 1 ng reduces the concen-
tration of the initial waste entering the lagoon thereby
t: reducing odors. So 1 i ds shciu 1 d be covered with effluent
at all times.
4. Keep vegetation on the embankment and areas adjacent to
the lagoon mowed.
F.. Repair- any eroded areas and .establish in vegetation.
6. Recommend that a suitable fence be constructed around
the lagoon for safety purposes.
7. The Clean Water Act of 1977 prop i b i t:s 'the discharge of.
po I 1 utants into waters of the United States; The
Department of Environment, Health and Natural Resources,
Division of Environmental Management, has the
r-espons i b i 1 1 ty.,for enforcing this 1 aw.
8. All surface runoff 1 s to be diverted from the lagoon to
stable ciutletsa

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 iu the_lagaon%r.peeriods_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. 'Thismeans that attlre first signs of plant growth in
the later winter/early spring, irrigation according to a farm waste..mapagement 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 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 capacitybeforq 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 suite -law and subject to penalty
action.
LAGOON MAINTENANCE
The routine maintenance of a lagoon involves the following:
✓ Maintenance of a vegetative coverforthe_ dam.. Fescueor 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 mustbeLcontrolled._ 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 herbicides mustnot be allowed to enter the
lagoon water. Such chemicals could harm the bacteria in the lagoon that are treatingthe 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:
1 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
1 Lagoon surface --- look for:
1. undesirable vegetative growth
2. floating or lodged debris
1 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 ice . action caused by strong winds.
These waves can erode the lagoon side walls, 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 side wall, baflies.inathe lagoon may be used to reduce the wave
impacts.
Any of these features could lead to erosion .and_weakening ofthe_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 providea temporary fix -if -there is -a -threat of a waste discharge.
However, a permanent solution should be.reviewed.by..the_techni al exert. Any digging into a
lagoon dam with heavy equipment is a serious undertakingwith 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_unimial% loud or grinding noise,
or a large amount of vibration, may indicate that the. pump isin need or repair or replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that
you are not completely "surprised" by equipment faihnre: You-shoul4 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 aredesigned_to-carry_ all. surface drainage waters
(such as rainfall runt 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 into 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-raln-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 rainfaTamount (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 inflow problem from a surface water
diversion or there may be seepage into the lagoon from the surrounding land.
Lagoon Operation
Startup:
l.. Immediately after construction establisha-cover on bare soil surfaces
to avoid erosion.
2. Fill new lagoon design treatmentvolume at least half -full of water before waste
loading begins, taking care .not .to_ erode lining or -bank slopes.
3. Drainpipes into the lagoon shouldrhave.arflexih1P_pipe_extender on the end of the
pipe to discl►arge 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 spriug 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 025percent 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 lithe 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,andexcessiveodor 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 wastewatetis added_to a lagoon,the a better the lagoon will.
fimction. 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 -- minimi7P_huildingwater usage and spillage from
leaking waterers, broken pipes and wash down through proper maintenance and
water conservation.
Minimize feed wastage and spillage by keepingfeeders adusted. 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.
1 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 datninthe_ spring based on nutrient requirements
and soil moisture so that temporary storagewill be maximized for the summer
thunderstorm season. Similarly, irrigate -in -the late-summerlearly-fall, to provide maximum
lagoon storage for the winter.
✓ The lagoon liquid level should never be --closer than_ . footto 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 18inchesundemeath_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 canfinement_houses or wherever they
are installed.
✓ Maintain strict vegetation, rodent,and varrnint..controlnear 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 isresponsible 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 fluched_waste, gravity settling_offnshed waste solids in an
appropriately designed basin, or
• minimizing feed wastage and spfilage.
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:
• I- ire 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 forage land; mix
remaining sludge; pump into liquid sludgeapplicator;. haul -and -spread onto cropland or
forage land; and soil incorporate.
• Dewater the upper part of lagoon.by irrigation_ontonearby cropland or forage land;
dredge sludge from lagoon with drag line 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_ozforage_land; and soil incorporate.
Regardless of the method, you must have the sludge-rniterial 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 tie limited by these nutrients as well as any
previous waste applications to that field and crop requirement.
When removing sludge, you must also pay. attentionto 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--beingdisturbed; pow 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 (Imaged 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 appliedto 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.phnsphorus,it_stihould 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 tbe_waske 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 ofwastewater frimlthe 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 theresponsibrh'ty for ensuring structure
safety. Items which may lead to lagoon failures include:
Modification of the lagoonstructure--- an_examp1e is_the placement of a pipe in
the dam without proper design and construction. (Consult an expert in lagoon
design before placing any pipe 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 quiekly- cause a large discharge of
wastewater and possible dam failure.
