The Irrigation Application Factors for each field in this plan are shown' in the following table. Infiltration rate varies with soils. If
applying waste nutrients through an irrigation sTstem, you must apply at a rate that will not result in runoff. This table provides the
maximum application rate per hour that may be applied id each field selected to receive wastewater. It also lists the maximum
application amount that each field may receive in any one application event. {

The Nutrient Management Recommendations table shown below provides an annual summary of the nutrient management plan
developed for this operation. This table provides a nutrient balance for the listed fields and crops for each year of the plan.
Required nutrients are based on the realistic yields of the crops to be grown, their nutrient requirements and soil test results. The
quantity of nutrient supplied by each source is also identified.
The total quantity of nitrogen applied to each crop should not exceed the required amount. However, the quantity of other
nutrients applied may exceed their required amounts. This most commonly occurs when manure or other byproducts are utilized
to meet the nitrogen needs of the crop. Nutrient management plans may require that the application of animal waste be limited so
as to prevent over application of phosphorous when excessive levels of this nutrient are detected in a field. In such situations,
additional nitrogen applications from nonorganic sources may be required to supply the recommended amounts of nitrogen.

The following Lagoon Sludge Nitrogen Utilization table provides an estimate of the number of acres needed for sludge
utilization for the indicated accumulation period. These estimates are based on average nitrogen concentrations for each source,
the number of animals in the facility and the plant available nitrogen application rates shown in the second column.
Lagoon sludge contains nutrients and organic matter remaining after treatment and application of the effluent. At clean out, this
material must be utilized for crop production and applied at agronomic rates. In most cases, the priority nutrient is nitrogen but
other nutrients including phosphorous, copper andtzinc can also be limiting. Since nutrient levels are generally very high,
application of sludge must be carefully applied.
Z _ 4
Sites must first be evaluated for their suitability for sludge application. Ideally, effluent spray fields should not be used for
sludge application. If this is not possible, care should be taken not to load effluent application fields with high amounts of
copper and zinc so that additional effluent cannot be applied. On sites vulnerable to surface water moving to streams and lakes,
phosphorous is a concern. Soils containing very high phosphorous levels may also be a concern.

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 rapacity.

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 condiltioiis, aad 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.

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'l, 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 pro-0ded the fields have been approved as a land
application site by a "technical specialist". Animai.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.

893937 Database Version 3.1 Date Printed: 9/5/2012 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 otherrestrictions 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): 2
Bermudagrass Coastal Plain, Mineral Soil, Poorly Drained to Somewhat Poorly Drained.
Adaptation: Effective artificial drainage MUST be in place to achieve Realistic Yield Expectations
provided for these soils.
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 1.0 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a
rate of 30 bu/ac is satisfactory to produce Mull 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 100 lb/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.

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 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 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 —actions 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 —actions include:

d. Stop all flows in the house, flush systems, or solid separators.
1 December 18, 1996

e. Repair all leaks prior to restarting pumps.
E. Leakage from base or side-,vall of lagoon. Often this is seepage as opposed to
flowing leaks —possible actions:
a. Dig a small sump or ditch away from the embankment 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 duration?
c. Any damage noted, such as employee injury, fish kills, or property damage?
d. Did the spill leave the property?
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. Are potable water wells in danger (either on or off of the property)?
h. How much reached surface waters?
3. Contact appropriate agencies.
A. During normal business hours, call your DWQ (Division of Water Quality)
regional office; Phone MOAi 15AAfter hours, emergency number: 1-800-858-0368.
Your phone call should include: your name, facility, telephone number, the details

Primary Secondary Routine Mortality
a 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 beat least one foot above the seasonal
high water table. Attach burial location map and plan.
aEl 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 ElA 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).
QMass 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.

SHEET 1 OF 2
OPERATION AND MAINTENANCE PLAN
This lagoon is designed for waste treatment (permanent storage) and
180 days of temporary storage. The time required for the planned
fluid level (permanent and temporary storage) to be reached may vary
due to site conditions, weather, flushing operations, and the amount
of fresh water added to the system.
The designed temporary storage consists of 180 days storage for:
(1) waste from animals and (2) excess rainfall after evaporation. Also
included is storage for the 25 year - 24 hour storm for the location.
The volume of waste generated from a given number of animals will be
fairly constant throughout the year and from yearto year, but excess
rainfall will vary from year to year. The 25 year rainfall will not
be a factor to consider in an annual pumping cycle, but this storage
volume must always be available.
A maximum elevation is determined in each design to begin
pumping and this is usually the outlet invert of pipe(s) from
building(s). If the outlet pipe is not installed at the elevation to
begin pumping, a permanent marker must be installed at this elevation
to indicate when pumping should begin. An elevation must be established
to stop pumping to maintain lagoon treatment depth.
Pumping can be started or stopped at any time between these two
elevations for operating convenience as site conditions permit, such as
weather, soils, crop, and equipment in order to apply waste without
runoff or leaching.
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 damage to crops.
The followino items are to be carried out:
1. It is strongly recommended that the treatment lagoon be pre -
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 witheffluent at all times. When precharging is complete,
flush buildings with recycled lagoon liquid. Fresh water should not
be used for flushing after initial filling.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see attachment)
before land application.
3. Begin temporary storage pump -out of the lagoon when fluid level
reaches the elevation 49.3 as marked by permanent marker. Stop pump -
out when the fluid level reaches elevation 47.2 . This temporary
storage, less 25 yr- 24 hr storm, contains 84443 cubic feet or
631636 gallons.

SHEET 2 OF 2
4. The recommended maximum amount to apply per irrigation is
. one (1) inch and the recommended maximum application rate is 0.3
inch per hour. Refer to the waste utilization plan for further details.
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.
S. Keep a minimum of 25 feet of grass vegetated buffer around
waste utilization fields adjacent to perennial streams. Waste will
not be applied in open ditches. Do not pump within 200 feet of a
residence or within 100 feet of a well. Waste shall be applied in a
manner not to reach other property and public right-of-ways.
9. 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.

OPERATION & MAINTENANCE PLAN
Proper lagoon liquid management should be a year-roundpriority_ 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 to allow for winter storage- livery effort should be made to
maintain the lagoon close to the minimum liquid level as long as the weather and waste utilization
plan wdl allow it.
Waiting until the lagoon has reached its maximwn.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 stoma is a violation of state law and subject to penalty
action.
LAGOON MAINTENANCE
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 embanlonent 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 thelagoon 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 mrn�m 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 ofpipes
✓ 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 --- skimps 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 dueto wave 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 damagecaused by wave action. If wave action causes
serious damage to a lagoon side wall, 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. thepump 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.anearly- 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 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 rain is predicted, and then record the
level again 4 to b 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 inplanningirrigation 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:
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_flexiblepipe extender on the end of the
pipe to discharge near the bottom of the lagoon during initial filling or another
means of slowing the incoming water to avoid erosion of the lining.
4. When possible, begin loading new lagoons in the spring to maximize bacterial
establishment (due to warmer weather).

5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon liquid
volume. This seeding should occur at least two weeks prior to the addition of
wastewater.
6. Maintain a periodic check on the.lagoon liquid.pfL If the pH falls below 7.0, add
agricultural lime at the rate of 1 pound per 1000 cubic feet of lagoon liquid volume
until the pH rises above 7.0. Optimum lagoon liquid pH is between 7.5 and 8.0.
7. A dark color, lack of bubbling, and excessive odor signals inadequate biological
activity. Consultation with a technical specialist is recommended if these
conditions occur for prolonged periods, especially during the warm season,
Loading:
The more frequently and regularly that wastewater.is..added. to. a_ lagoon, the better the lagoon will
function. Flush systems that wash waste into the lagoon several times daily are optimum for
treatment. Pit recharge systems, in which one or more buildings are drained and recharged each
day, also work well.
Practice water conservation --- minimize building -water usage and spillage from
leaking waterers, broken pipes and wash down through proper maintenance and
water conservation.
Minimize feed wastage and spillage by keeping feeders. adjusted. This will reduce
the amount of solids entering the lagoon
Management:
✓ Maintain lagoon liquid level between the permanent storage level and the full temporary
storage level.
✓ Place visible markers or stakes on the lagoon bank to show the
minimum liquid. level and the maximum liquid 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.
✓ 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.
✓ K animal production is to be terminated, the owner is responsible for obtaining and
implementing a closure plan to eliminate the_possbility 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:
• Mire a custom applicator.
• Mix the sludge and lagoon liquid with a chopper -agitator impeller pump through
large -bore sprinkler irrigation system ontonearby cropland;- and soil incorporate..

• Dewater the upper part of lagoon by irrigation onto nearby cropland or forage land; mix
remaining sludge; pump into liquid sludge applicator;.haut and spread onto cropland or
forage land; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby 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 or forage land; 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 fieldswill.be.limited by these nutrients as well as any
previous waste applications to that field and crop requirement.
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. landmith_ 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 phosphorus, it should be applied only at
rates equal to the crop removal ofphosphorus. As with other wastes, always have your lagoon
sludge analyzed for its nutrient value.
The application of sludge will increase the amountof odorat 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 rapture 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.
