APPLICATION METHOD:
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 implementin plan in order to maximize the fertilizer valueyof rtheste wasteut1andatoon
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.

Acres shown in each of the preceding tables are considered to be the
usable acres excluding required buffers, filter 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 fields 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 1065.6 pounds of plant available nitrogen per year in the
sludge.
If you remove the sludge every 5 years, you will have approximately 5328
pounds of PAN to utilize. Assuming you apply this PAN to hybrid
bermudagrass hayland at the rate of 300 pounds of nitrogen per acre, you
will need 17.76 acres of land. If you apply the sludge to corn at
the rate of 125 pounds of nitrogen per acre, you will need 42.624 acres
of land. Please be aware that these are only estimates of the PAN and
land needed. Actual requirements could vary by 2596 depending on your
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 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 irrigate the acres
shown in Tables 1 and 2. Failure to apply the recommended rates and
Page: 7

Call your technical specialist after you receive the waste analysis
report for assistance in determining the amount of waste per acre and
the proper application rate prior to applying the waste.
NARRATIVE OF OPERATION
THIS PLAN IS WRITTEN BASED ON A TWO YEAR CROPPING ROTATION. THE PAN HAS BEEN
DOUBLED TO ACCOUNT FOR THIS ROTATION. THE DOMINANT SOIL TYPE HAS BEEN USED FOR
EACH FIELD. MR GRADY DOES NOT NEED A WETTED ACRES DETERMINATION. THE ACRES
USED FOR EACH FIELD ARE LESS THAN 75% OF THE TOTAL FIELD ACRES SHOWN ON CFSA
MAPS. THERE MAY BE TOBACCO ROTATED IN FIELDS ONE AND TWO AS NEEDED TO
ACCOMODATE MR GRADY'S FARMING OPERATION. ALL OF FIELD ONE, OR NO MORE THAN TEN
ACRES OF FIELD TWO MAY BE PLANTED IN TOBACCO DURING ANY GROWING SEASON. THE
TOTAL REMAINING ACRES PLANTED TO THE ROTATIONS AS SHOWN IN THIS WUP WILL MEET
TRE NUTRIENT BUDGET NEEDS FOR THIS OPERATION.

Emergency Action Plan
This plan will be implemented in the event that wastes from you operations are leaking, overflowing,
or running off the site. You should NOT wait until wastes reach surface waters or leave your
property to consider that you have a problem. You should make very effort to ensure that this does
not happen. This plan should be available to all employees at the facility, as accidents, leaks, and
breaks can happen at any time.
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:
• add soil to the berm to increase the elevation of the dam
• pump wastes to fields at an acceptable rate
• stop all additional flow to the lagoon (waterers)
• call a pumping contractor
• make sure no surface water is entering the lagoon
Note: These activities should be started when your lagoon level has exceeded the temporary
storage level.
b) Runoff from waste application field:
• immediately stop waste application
• create a temporary diversion or berm to contain the waste on the field
• incorporate waste to reduce further runoff
c) Leaking from the waste distribution system:
• pipes and sprinlders:
© stop recycle (flushing system) pump
® stop irrigation pump
• close valves to eliminate further discharge
separate pipes to create an air gap and stop flow
Page 1

• flush system, houses, solids separators:
• stop recycle (flushing system) pump
• stop irrigation pump
© make sure no siphon effect has been created
© separate pipes to create an air gap and stop flow
d) Leakage from base or sidewall of the lagoon. Often these are seepage as opposed
to flowing leaks:
• dig a small well or ditch to catch all seepage, put in a submersible pump, and
pump back into the lagoon
• if holes are caused by burrowing animals, trap or remove animals and fill holes
and compact with a clay type soil.
• other holes may be likewise temporarily plugged with clay soil.
Note: For permanent repair measures, lagoon problems require the consultation of an individual
experienced in their design and installation.
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 duration?
c) Any damage noted, such as employee injury, fish kills, or property damage?
3) Contact appropriate agencies.
a) During normal business hours, call your DWQ regional office: 910-395-3900; after hours,
emergency number: 800-858-0368 or 919-733-3942. Your phone call should include:
your name, facility, telephone number, the details of the incident, the exact location of the
facility, and the location or direction of movement of the spill, weather and wind
conditions, what corrective measures have been taken, and the seriousness of the
situation.
b) Your integrator: Goldsboro Hog Farms Division, Maxwell Foods, Inc.
919-778-3130 extension 1430
c) If the spill leaves the property or enters surface waters, call the local EMS:

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.
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
13B .0200.
Rendering at a rendering plant licensed under G.S. 106-168.7.
Complete incineration according to 02 NCAC 52C .0102.
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 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).
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 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 liquid management should be a year-round priority. It is especially
important to manage levels so that you do not have problems during extended rainyand
wet periods.
Maximum storage capacity should be available in the lagoon for
receiving crop is dormant (such as wintertime for bermudagrass) periods
en herhene the
extended rainy spells such as the thunderstorm season in th
that at the first signs of plant growth in the later winter/early sprig, irrgationl acco din to
a farm waste management plan should be done whenever the land is dry enough to g
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 sta.rtin to
irrigate does not leave room for storing excess water during extended wet g
Overflow from the lagoon for any reason except a 25-year, 24-hour storm is aoviolation of
state law and subject to penalty action.
The routine maintenance of a Iagoon 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 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

• 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 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
of a waste discharge. However, a permanent solution should erwed by the is a threat
technical expert. Any digging into a Iagoon 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 or repair or
replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that you
are not completely "surprised" by equipment failure, You should perform your pumping
system maintenance at a time when your lagoon is at its low level. This will allow some
safety time should major repairs be required. Having a nearly full lagoon is not the time
to think about switching, repairing , or borrowing pumps. Probably, if your lagoon is full,
your neighbor's lagoon is full also. You should consider maintaining an inventory of 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,
have an inflow problem from a surface water diversion or there may be seege 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.
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 initial
filling or another means of slowing the incoming water to avoid erosion of
the lining.
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.
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 occour at least two weeks prior to the
addition of wastewater.
6. Maintain a periodic check on the lagoon Iiquid 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,

•
Management:
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 entenng the lagoon
Maintain lagoon liquid level between the permanent storage level and
the full temporary storage level.
Place visible markers or stakes on the lagoon bank to show the
minimum liquid level and the maximum liquid lever (Figure 2-1).
Start irrigating at the earliest 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 Ievel 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 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:

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 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 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 darn.
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.
