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 the implementing your waste utilization plan in order to
maximize the fertilizer value of the wapte 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 not be applied to land eroding at more 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 in runoff to the surface waters which is not
allowed under DWQ regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor problems.
6. To maximize the value of the nutrients for crops 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 applications 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. Acreage requirements should be based on the waste analysis report frQrr�_
your waste management facility. In some cases you may want to have plant analysis- e, which

V�ard Parker Farm
Page 2
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 the 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.

Ward Parker Farm Page 3
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 bermudagrass), 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 to reach materity,
especially late in the season ( i.e. April or May) Shading may result if small grain gets too high and this will
definitely interfere with the stand of bermudagrass. This loss of stand will result in reduced yields and less
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 mowed to a height of about two inches before drilling for best
results.
Caution must be exercised in grazing or haying summer annuals under stressed conditions. Nitrate poisoning
may occur in livestock. Sampling forage or hay for nitrate levels is recommended.
Acres shown in the tables are considered to be the usable acres excluding required buffers, filters strips along
ditches, odd areas unable to be irrigated, and perimeter areas not receiving full application rates due to
equipment limitations. Actual total acres in the field listed may, and most likely will be, more than the acres
shown in the tables.
See attached map showing the fields to be used for the utilization of animal waste.
SLUDGE APPLICATION:
The waste utilization plan must contain provisions for periodic land application of sludge at agronomic rates.
The sludge will be nutrient rich and will require precautionary measures to prevent over application of nutrients
or other elements. Your production facility will produce approximately 1422 lbs. of plant available
nitrogen per year in the sludge.
If you remove sludge every 5 years you will have approximately 7110 lbs. of PAN to utilize. Assuming
you apply this PAN to hybrid bermudagrass hayland at the rate of 300 lbs/acre you will need 24
acres of land. If you apply the sludge to corn at the rate of 125 lbs. of nitrogen per acre you will need 57
acres of land. Please be aware that these are only estmates of the PAN and the land needed. Actual
requirements could vary by 25% depending on the sludge waste analysis, soil types, realistic yields, and
application methods.
APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation such that
runoff or ponding occurs. This rate is limited by initial soil moisture content, soil structure, soil texture, water
droplet size, and organic solids. The application amount should not exceed the available water holding capacity

Ward Parker Farm
Page 4
of the soil at the time of irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of
the crop.
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 irrrigate the acres shown in tables.
Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan
invalid.
The following table is provided as a guide for establishing application rates and amounts.

This is the maximum application amount allowed for the soil assuming the amount of nitrogen allowed for the
crop is not over applied. In many situations the application amount shown cannot be applied because of the
nitrogen limitations. The maximum application amount shown can be applied under optimum soil conditions.
Your facility is designed for 180 days of temporary storage and the temporary storage rnust be removed on the
average of once every 6 months. In no instances should the volume of the waste be stored in your structure
be within the 25 year 24 hour storm storage or one foot of freeboard except in the event of the 25 year 24 hour
storm.
It is the responsibility of the producer and the waste applicator to ensure that the spreader equipment is operated
properly to apply the correct rates shown in the tables. Failure to apply the recommended rates and amounts of
nitrogen shown in the tables may make this plan invalid.
Call your technical specialist after you have receive the waste analysis report for assistance in determining the
amount of waste per acre and the proper application rate prior to appling the waste.

This plan will be implemented in the event that wastes from your
operation are leaking, overflowing, or running off the site. You should
NOT wait until wastes re'ac"h 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 employees 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 problems are
listed below:
A. Lagoon overflow -possible solutions are:
a. Add soil to berm to increase elevation of dam, any
permanen't'alteration of the dam -should be approved b-y a
qualified technical.specialist.
b.,. Pump wastes- to field'at an acceptab le rate.
c. Stop,all additional flow to the lagoon -hold waste.in the
house if possible.
d. Call a pumping contractor.
e. Make sure no surface water is entering lagoon.
.B. Runoff from waste application field-ac . tion include:
a. Immediately stop waste application.
b. Create a temporary diversion orberm to contain the
waste.
c. Incorporate waste 'to reduce further runoff.
d. Lvaluate and eliminate the 'reason(s). that caused the
runoff.

d. Stop all flows in the house, flush systems, or solid
.separators.
e. Rep�iir;- all leaks prior to restarting pumps.-

I
E. Leakage from base or sidewall of lagoon. Often this is seepage
as opposed to flowing leaks -possible action:
a. Dig a small sump or ditch to catch all seepage, put in a
submersible pump, and pump back into 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 the lagoon bottom as soon as possible.
2. Assess the extent of th� spill and note any obvious damages.
a. Did the waste reach any surface waters?
b. Approximately how much was released and for what
duration?
c. Any damage noted, such as employee injury, fish kills, or
property damage?
d. Did -the spill leave the proper.ty?
e. Does the spill have' the potential to reach surface
waters?
f. Could'a future rain event cause the spill to reach
surface waters?
g'. Ore potable water wells in danger (e'i'ther on or off of
the property)?
h. How much reached surface waters?
3. Contact appropriate agencies.

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.
Primary Secondary Routine Mortality
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. - :,
Landfill at municipal solid waste facility. permitted by NC DEQ under GS 15A NCAC
E] D 13B .0200.
Rendering at a rendering plant licensed under-G.S. 106-168..7.
Complete incineration according to 02 NCAC 52G.,0 102.
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.
In the case of dead poultryonly, placing in a disposal pit of a size and design approved by the
E] D NC Department of Agriculture & Consumer Services (G.S. 106-549.70).
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).
Mass Mortality Plan
Mass mortality plans are. required for farms covered by an NPDES permit. These plans are
also recommencled. for all animal operations. This plan outlines farm -specific mortality man-
agement methods to be used for mass mortality. The NGDA&CS Veterinary Division sup-
ports a variety of emergency mortality disposal options;, contact the Division for guidance.
• A catastrophic mortality disposal plan is partrof the. -facility's CAWMP and is activated
when numbers of dead animals exceed normal mortality rates as specified by the State
Veterinarian. I I.
• Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary
Division regulations and guidance.
• Mass burial sites are subjectto additionalpermit, conditions (referto 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 & MAINTUN ANCE PLAN
Proper lagoon liquid management should be a yea - ound pricrity., It is especiallyi
important to manage levels so that you do not have roblems during extended rairi'y and
wet periods.
Maximum storage capacity should be available in the lagoon for periods when thel
receiving crop is - dormant.(such as wintertime for bet mlodagrass) or when there ar�, I
extended rainy spells such as the thunderstorm season in the surnmertime. This m�ans
thatat the first signs of plant growth in the later wjnter�early spring, irrigation accor4ing to
a farm waste management plan should be done whe- never the land is dry enough to'
receive lagoon liquid. This will make storagespace vailable in the lagoon fo� fut'r et
Y e W
periods. in the late summerlearly fall the lagoon sho ld be pumped down to the I `P`W
marker (see Figure 2-1) to allow for winter storage. very 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 45 maximum storage capa-city before starting to
irrigate does not leave room for storin.g 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 vegeWive
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 ye�r, the I�Lgoon embankment and surrounding areas
sho u Id be ferti I iZed With 800 pounds per acre of 10- 10-10, or
equivalent.
Brush and trees on the embankment must be controiled. This may be
done by mowing, spraying, grazing, chopping, or a combiration of
these practices. This should be done at least once a year and
possibly twice in years that weather conditions are favorablefor
heavy vegetative growth.
;N-'C)T[-: If vegetation is controlled by spraying, the herbilcide rnu5t not be allowed to enter
t 1. hernicals ould-1 ar I
Lhe lagoor, water. Such C h . m the bacteria in the 'agoon that are treating
the waste.
Mai riteriance rispections of the entire lagoon should bo made during theinitial filling of
lagoon ard at least monthly and after major rainfah and st-on" events, Items to be
-n
checked should include, as a minim un , ffie following:
Wastp Inlet Pipes, -Recycling Pipes, ard Ovprifov� Pipes —look for:
I . separationof Joi.rits
2. cracks or breaks
ac.-ur-nulation of salts Or rmneri�
,a over2l'! conditi-n of pipe�

Lagoon surface —look for:
I . undesirable vegetative growth
2. floating or lodged debris
Embank ' ment—look for:
settlement, cracking,'or ',jug" holes
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 wavf
5. rodent damage
Larger lagoons may be subject to finer damage due to wave action cause by strong
winds. These waves can erode the lagoon sidewills, thereby weakening he fagoon dam.
A good stand of vegetation will reduce the poteniial damage caused by Ja�ve action. if
wave action causes serious damag'a 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". Hrewever, a permanent soluition should be reviewed by the
technical expeq. Any dig-g,ing into a lagoon dam with heavy equipme'nt is a serious
undertaking with potentially serious consequences and should not be conducted unless
recommended by an appropriate technical exper-t.
Transfer Pumps —check for proper operation of;
1 . recycling pumps
2. irrigation pumps,
Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding
noise, or a large amount of vibration,- may indicate that the pump is in need or repair or
replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that you
are not completely "surprised" by equipment failure. You should perform your pumping
system maintenance at a time when your lagoon' is at its low!evel. This will allow some
safety time -should majoIr repairs be required. Having a nearly full lagoon is not the tinne
to think about switching, repairing, or borrowing pumps. Probably, it' your lagoon is full,
your neighbor's lagoon is full also. You should consider maintaining an inventory ofspare
par-L5 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 runofO 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
I lic
kwashing) system pipes and the rainfall that hits the lagoon directly.
You should inspect your diversion system for the following:
I . adequate vegetation
2. di -version capacity
3. ridge berm height

,den ti f ied Problems should be coIrrected promptly. It is advisable to insDect your system
during or immediately following a heavy rain. If technical assistance isneeded to
determine proper solutions, consol� with appropriate experts.
You should record the level of th;,- a oon just prior to.when. rain is predicted, and then
record tk'e level again 4 to 6 hour !aRer th
I e rain (assurnes 'there is no pumping). This will
give you an idea of how much yo � lagoon level will rise with a certain rainfall amount
(you must also be recording your ajnfall for this to work), Knowing this should help in
Id I
planning irrigation applications at !storage. If your lagoon rises excessively, you may
have an inflow problem from a s rf acc, water diversion or there may be seepage into the
lagoon from the surrounding Ian
Lagoon Operation
Startup: I
Immediatelv after construction establish a complete sad cover on bare soil
surfaces to �void 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. tp
4. When possible, begin loading new lagoons in the spring to maximize
bacteria] establishment (due to warmer weather).
5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon
liquid volume. This seeding should occour at least two weeks prior to the
addition of wastewater.
6. Maintain a periodic check an the lagoon liquid pH. if the pH falls be!ow
7.0, add agricultural lime at the rate of i pound per 7 300 cubic feet of
lagoon liquid volume until the pH rises above 7.0. 0o'kimum 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
5eason.
= B
The more frequently and regularly that wastewater is added to a !a -coo, the berter the
lagoon MIN function. Flush systems that wash waste into the lagoon several Hmes daily are
optimum 'or fteatment. Pit recharge systems, in which one or more buildings are drained
and recharged each day, also work weil.

I
Practice warer con servation—min i mize building water. -usage and
spillage from leaking waterers,' broken pipes and wa-shdown through
proper maintenance and water con.servation.
Minimize feed wastage and spillage by keeping feed e rs'adj'u sted. Thi5
U
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 levW and the.maximurn liquid lever (Figure 2-1).
Start irrigating at the earliest possible date in the spring based or]
nutrient requ.irements and soil moisture so that temporary storage
will be maximized for the 5ummerlhunderstorm season. Similarly,
irrigate in the late summer/early fall'to provide maximum lagoon
storaoe for the winter.
C2 -
The lagoon fiquid 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-sternmeed forage or vegetation,
molded feed, plastic syringes, or other foreign materials into the lagoon.
Frequently- remove solids from catch basins at end of confin-ement houses or
wherever they are installed.
Maintain strict vegetation, rodent, and varmint control near lagoon edges.
0
Do not allow trees or large bushes to grow on lagoon dam or embankment.
Remove sludge frorn the lagoon either when the sludge storage capacity is
full or before it fills 50 percent of the permanent storage volume.
If animal produ�tion is to be terminat0d, the owner is responsible for
obtainina and implementing a closure p,an to eliminate the possibility of a

Sludge Removal:
Rate of lagoon sludge buildup can be reduced by-.

proper lagoon sizing,
mechanical solids separation of flushed waste,
gravity 5ettling of flushed waste solids in an' appropriately designed basin,
I minimizing feed wastage and spillage.
Lagoon sludge that is removed annuafly 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 appli(fator.
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 remainmg 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 a ' ny previous waste applications to that field and crop
.requirement. Waste application rates will be discussed in detail in Chapter 1.
When removing sludge, you must also pay attention to the liner to prevent damace, Close
attention by the pumper or drag -line operator will ensure that the lagoon liner rem6ains
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 dimaged it must be repaired as soon as
possible.
sludge removed from the lagoon has a much higher"phosphorus and heavy metal con -Lent
than liquid, Because of this it 5hould probably he applied to land with lo%�, 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 soii-test phosphores, it
should be applied only at rates equal to the crop. removal of phosphorus. As with othe'r
wastes, always have your lag6on sludge analyzed for its nutrient value.,
Tne application of sludge will increase the amount'of odor at thie waste appiication site.
�_xtra precaution should be used to obsewe the wind directicio and other conditions which
increase the concern of neighbors.

Possible Catises of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure. Types
