Narrative
This WUP is written based on a wetted acres footprint completed by Star Maready Jackson. At times if
Mr Barwick wishes the Summer Annual crop may be substituted with Corn or Soybeans. When this is
done the following Nitrogen rates must be used for those crops.
Corn PAN 125LbsN/Ac Application Dates 2/15 -- 6/30
Soybeans PAN 140LbsN/Ac Application Dates 4/1-- 9/15
The deficient with corn(crop using least PAN) will be approximately ( 398.35) as listed in the Waste
Utilization Table for this WUP.
The application rates and amounts for these pull will remain the same as listed in tables.

NOTE: Symbol * means user entered data.

The Waste Utilization table shown below summarizes the waste utilization plan for this operation. This plan provides an estimate of the number of acres of cropland needed to use
the nutrients being produced. The plan requires consideration of the realistic yields of the crops to be grown, their nutrient requirements, and proper timing of applications to
maximize nutrient uptake.
This table provides an estimate of the amount of nitrogen required by the crop being grown and an estimate of the nitrogen amount being supplied by manure or other by-products,
commercial fertilizer and residual from previous crops. An estimate of the quantity of solid and liquid waste that will be applied on each field in order to supply the indicated quantity
of nitrogen from each source is also included. A balance of the total manure produced and the total manure applied is included in the table to ensure that the plan adequately provides
for the utilization of the manure generated by the operation.

The Available Waste Storage Capacity table provides an estimate of the number of days of storage capacity available
at the end of each month of the plan. Available storage capacity is calculated as the design storage capacity in days
minus the number of days of net storage volume accumulated. The start date is a value entered by the user 'and is
defined as the date prior to applying nutrients to the first crop in the plan at which storage volume in the lagoon or
holding pond is equal to zero.
Available storage capacity should be greater than or equal to zero and less than or equal to the design storage
capacity of the facility. If the available storage capacity is greater than the design storage capacity, this indicates that
the plan calls for the application of nutrients that have not yet accumulated. If available storage capacity is negative,
the estimated volume of accumulated waste exceeds the design storage volume of the structure. Either of these
situations indicates that the planned application interval in the waste utilization plan is inconsistent with the
structure's temporary storage capacity.

Required Specifications For Animal Waste Management
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 that 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. If the producer does not own adequate land to properly dispose of the
waste, he/she shall provide evidence 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 waste production facility to
secure an update of the Nutrient Management Plan when there is a change in the
operation, increase in the number of animals, method of application, receiving
crop type, or available land.
3. Animal waste shall be applied to meet, but not exceed, the nitrogen needs for
realistic crop yields based upon soil type, available moisture, historical data,
climatic conditions, and level of management, unless there are regulations that
restrict the rate of applications 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 eroding at more than 5 tons per acre per year but
less than 10 tons per acre per year provided grass filter strips are installed where
runoff leaves the field (see USDA, NRCS Field Office Technical Guide Standard
393 - Filter Strips).
5. Odors can be reduced by injecting the waste or by disking after waste application.
Waste should not be applied when there is danger of drift from the land
application field.
6. When animal waste is to be applied on acres subject to flooding, waste will be soil
incorporated on conventionally tilled cropland. When waste is 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 and flies.
546618 Database Version 3.1 Date Printed: 3/30/2009 Specification Page 1

8. Animal waste shall not be applied to saturated soils, during rainfall events, or
when the soil surface is frozen.
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. Nutrients from waste 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 canal. Animal waste, other than swine waste
from facilities sited on or after October 1,1995, shall not be applied closer that 25
feet to perennial waters.
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 not 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 cropland provided the fields 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.
546618 Database Version 3.1 Date Printed: 3/30/2009 Specification Page 2

17. A protective cover of appropriate vegetation will be established on all disturbed
areas (lagoon embankments, berms, pipe runs, etc.). Areas shall be fenced, as
necessary, to protect the vegetation. Vegetation such as trees, shrubs, and other
woody species, etc., are limited to areas where considered appropriate. Lagoon
areas should be kept mowed and accessible. Berms and structures should be
inspected regularly for evidence of erosion, leakage, or discharge.
18. 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.
19. 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.
20. 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, it should only be applied pre -plant with no further
applications of animal waste during the crop season.
21. 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 the markers. A
marker will be required to mark the maximum storage volume for waste storage
ponds.
22. 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 nutrient, unless other restrictions require waste to be applied
based on other nutrients, resulting in a lower application rate than a nitrogen
based rate. 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 and maintained for optimum crop production. Soil and waste analysis
records shall be kept for a minimum of five years. Poultry dry waste application
records shall be maintained for a minimum of three years.
Waste application records for all other waste shall be maintained for five (5)
years.
23. Dead animals will be disposed of in a manner that meets North Carolina
regulations.

Crop Notes
The following crop note applies to field(s): 1, 2, 3, 4, 5, 6, 7, 8, 9
Small Grain: CP, Mineral Soil, medium leachable
In the Coastal Plain, oats and barley should be planted from October 15-October 30; and rye from
October 15-November 20. For barley, plant 22 seed/drill row foot and increase the seeding rate by 5% for
each week seeding is delayed beyond the optimum time. See the seeding rates table for applicable
seeding rate modifications in the current NCSU "Small Grain Production Guide". Also, increase the
initial seeding rate by at least 10% when planting no -till. Oats should be planted at 2 bushels/acre and
rye at 1-1 1/2 bushels/acre. Plant all these small grains at 1-1 1/2" deep. Adequate depth control is
essential. Review the NCSU Official Variety "green book" and information from private companies to
select a high yielding variety with the characteristics needed for your area and conditions. Apply no more
than 30 lbs/acre N at planting. Phosphorus and potash recommended by a soil test can also be applied at
this time. The remaining N should be applied during the months of February -March.
The following crop note applies to field(s): 1, 2, 7, 8, 9
Bermudagrass: CP, Mineral Soil, Moderately Well Drained.
Adaptation: Well -adapted.
In the Coastal Plain, hybrid bermudagrass sprigs can be planted Mar. 1 to Mar. 31. Cover sprigs 1" to 3"
deep (1.5" optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and .
wind. For Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a
rate of 30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing
conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced 1' to 1.5' in row.
For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime, phosphorus,
potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 1001b/ac N in
the establishment year in split applications in April and July. For established stands apply 180 to 240
lb/ac N annually in split applications, usually in April and following the first and second hay cuts.
Reduce N rates by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization
of Pastures and Forages in North Carolina for more information or consult your regional agronomist or
extension agent for assistance.

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
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.
El El 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).
a 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 tempory procedures or measures for disposal according to G.S. 106-399.4

County:DUPLIN
Your animal waste management facility has been designed for a
given storage capacity. When the waste reaches the designed
level, it must be land applied at a specified rate to prevent
pollution of surface and/or ground water. The plant nutrients
in the animal waste should be used to reduce the amount of
commercial fertilizer required for the crops on 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 and annual soil tests
are 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 and leaching potential. Waste shall not be applied to
land eroding at greater than 5 tons per acre per year. Do not
apply waste on saturated soils or on land when the surface is
frozen. Either of these conditions may result in runoff to
surface waters. 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
not more than 30 days prior to planting. Injecting the waste
or disking will conserve nutrients and reduce odor problems.
The acres needed to apply the animal waste is based on typical
nutrient content for this type of facility. Acreage
requirements may be more or less based on the waste analysis
report from your waste management facility.
The design of your waste management facility is based on the
following:
Amount of Waste Produced Per Year:
1760 animals x 1.9 tons waste/animal/yr= 3344 tons
total waste
R

Page 2
Amount of Plant Available Nitrogen Produced Per Year:
1760 animals x 2.30 lbs. N/animal/year = 4048 lbs./yr
Available N
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. Your facility is designed for 180 days of
storage. Therefore, it will need to be pumped every 6
months.

OPERATION AND MAINTENANCE PLAN
This lagoon is designed for waste treatment with minimum odor
control. The time required for the planned fluid level to be
reached may vary due to soil conditions,flushing operations, and
the amount of fresh water added to the system.
Land application of waste water is recognized as an acceptable
method of disposal. Methods of application include solid set,
center pivot, guns, and traveling gun irrigation. Care should be
taken when applying waste to prevent runoff from the field or damage
to crops.
The following items are to be carried out:
1. It is strongly recommended that the treatment lagoon be lire -
charged to 1/2 its capacity to prevent excessive odors during
start-up. Pre -charging reduces the concentration of the initial
waste entering the lagoon thereby reducing odors. Solids should be
covered with effluent at all times.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see Attachment B)
before land application.
3. Begin pump -out of the lagoon when fluid level reaches eleva-
tion 42.1 as marked by permanent markers. Stop pump -out when
the fluid level reaches elevation 40.2 or before fluid depth is
less than 6 feet deep (this prevents the loss of favorable
bacteria) .
4. The recommended maximum amount to apply per irrigation is
one (1) inch and the recommended maximum application rate is 0.4
inch per hour.
5. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
6. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable
outlets.
8. The Clean Water Act of 1977 prohibits the discharge of
pollutants into waters of the United States. The Department of
Environment, Health, and Natural Resources, Division of Environ-
mental Management, has the responsibility for enforcing this law.

SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS
Clearing:
All trees and brush shall be removed from the construction area
before any excavating or fill is started. Stumps will be removed
within the area of the foundation of the embankment and fill areas
and all excavated areas. All stumps and roots exceeding one (1)
inch in diameter shall be removed to a minimum depth of one (1)
foot. Satisfactory disposition will be made of all debris. The
foundation area shall be loosened thoroughly before placement of
embankment material.
Cut-off Trench:
A cut-off trench (when specified) shall be installed as shown in
the plans.
Construction:
Construction of excavated and earthfill areas shall be performed to
the neat lines and grades as planned. Deviations from this will
require prior approval of the SCS. Earthfill shall not be placed
in standing water and reasonable compaction of the fills shall be
performed by the construction equipment or sheeps-foot roller during
placement. The embankment of the lagoon shall be installed using
the more impervious materials. Construction of fill heights shall
include ten (10) percent for settlement. To protect against seepage,
when areas of unsuitable material are encountered, they will need to
be excavated a minimum of one (1) foot below grade and backfilled and
compacted with a suitable material (ie-CL,SC,CH). Refer to the soils
investigation information in the plans for special considerations.
Precautions should be taken during construction to prevent excessive
erosion and sedimentation.
Vegetation:
All exposed embankment and other bare constructed areas shall be
seeded to the planned type of vegetation as soon as possible after
construction.

EMERGENCY ACTION PLAN
Using this outline as guidance, you should develop a specific emergency action plan for
your waste handling system. 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 reach surface waters or leave yourproperty to consider that you have a
problem. You should make every effort to ensure that this does not happen. This plan
should be available to all employees at the facility, as accidents, leaks, and breaks could
happen at any time. Your plan should follow this format:
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:
▪ add soil to berm to temporarily increase elevation of dam —any
permanent alteration of the dam should be approved by a
qualified technical specialist
pump wastes to field at an acceptable rate
stop all additional flow to the lagoon (waterers) —hold waste in
house if possible
call a pumping contractor.
make sure no surface water is entering lagoon
NOTE: These activities should be started when your lagoon level has exceeded the
temporary storage level.
b. Runoff from waste application field —actions include:
immediately stop waste application
• create a temporary diversion or berm to contain the waste on
the field
incorporate waste to reduce further runoff
c. Leakage from the waste distribution system:
• pipes and sprinklers —actions include:
- stop recycle (flushing system) pump
- stop irrigation pump
- close valves to eliminate further discharge
- separate pipes to create an air gap and stop flow
flush system, houses, solids separators —actions include:
- 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 lagoon. Often these are seepage as
opposed to flowing leaks —possible action*:
▪ dig a small well or ditch to catch all seepage, put in a
submersible pump, and pump back into 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
*Lagoon problems require the consultation of an individual
experienced in the design and installation of lagoons for permanent
repair measures.

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 notes, such as employee injury,fish kills, or property
damage?
3. Contact appropriate agencies.
a. During normal business hours, call your DEM regional office, at
910-395-3900, after hours, emergency number: 919-733-3942.
Your phone call should include: your name, facility, telephone
number, the details of incident from item 2 above, 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 under taken,
and the seriousness of the situation.
b. If spill leaves, or is likely to leave, property or enters surface
waters, call local emergency management services (EMS) at 910-296-
2160.
c. Instruct EMS to contact local Health Department.
d. Contact local Soil and Water Conservation District
Natural Resources Conservation Service office at 910-296-2121,
and Cooperative Extension Service at 910-296-2143for
advice/technical assistance.
e. If you are a contract swine grower associated with a swine company
integrator, contact the company representative.
4. Implement procedures as advised by DEM and technical assistance
agencies to rectify the damage, repair the system, and reassess the
waste management plan to keep problems with release of wastes from
happening again.

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 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 the thunderstorm season in the summertime. This means
that at the first signs of plant growth in the later winter/early spring, irrigation according to
a farm waste management 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 (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
irrigate does not leave room for storing excess water during extended wet periods.
Overflow from the lagoon for any reason except a 25-year, 24-hour storm is a violation of
state law and subject to penalty action.
The routine maintenance of a lagoon involves the following:
Maintenance of a vegetative cover for the dam.
Fescue or common bermudagrass are the most common vegetative
covers. The vegetation should be fertilized each year, if needed, to
maintain a vigorous stand. The amount of fertilizer applied should be
based on a soils test, but in the event that it is not practical to obtain
a soils test each year, the lagoon 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 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 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, 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:
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 occour 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 000 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 entering the lagoon
Maintain lagoon liquid level between the permanent storage level and
thefull 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 level -should never be closer than 1 foot to the lowest
point of the dam or embankment.
Do not pump the lagoon liquid level lower that the permanent storage
level unless you are removing sludge.
Locate float pump intakes approximately 18 inches underneath the liquid
surface and as 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.
Frequentlyremove 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 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 rnoving.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.
