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.
a 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).
DAny 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 eve f imminent threat of a disease emergency, the State Veterinarian may enact
additionIteporary procedures or measures for disposal according to G.S. 106-399.4.

The table shown below provides a summary of the crops or rotations included in this plan for each field. Realistic Yield estimates are
also provided for each crop,as well as the crop's P205 Removal Rate. The Leaching Index(LI)and the Phosphorous Loss Assessment
Tool(PLAT)Rating are also provided for each field,where available.
If a field's PLAT Rating is High, any planned manure application is limited to the phosphorous removal rate of the harvested plant
biomass for the crop rotation or multiple years in the crop sequence. Fields with a Very High PLAT Rating should receive no
additional applications of manure. Regardless of the PLAT rating, starter fertilizers may be recommended in accordance with North
Carolina State University guidelines or recommendations. The quantity of P205 applied to each crop is shown in the following table if
the field's PLAT rating is High or Very High.

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 system,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 to 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 and zinc can also be limiting. Since nutrient levels are generally very high,
application of sludge must be carefully applied.
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 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.
448355 Database Version 3.1 Date Printed: 8/11/2005 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.
---------------------------------------------------- --------- - ----- - -------
448355 Database Version 3.1 Date Printed: 8/11/2005 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): Ia,2
Corn CP, Organic Soils
In the Coastal Plain, corn is normally planted when soil temperatures reach 52 to 55 degrees fahrenheit.
Review the Official Variety "green book" and information from private companies to select a high
yielding variety with the characteristics needed for your area and conditions. Plant 1-2" deep.Plant
populations should be determined by the hybrid being planted. Increase the seeding rate by 10%when
planting no-till. Phosphorus and potassium recommended by a soil test can be broadcast or banded at
planting. When planting early in cool, wet soil,banded phosphorus will be more available to the young
plants. An accepted practice is to apply 20-30 lbs/acre N and 20-30 lbs/acre phosphorus banded as a
starter and one-half the remaining N behind the planter. The rest of the N should be applied about 30-40
days after emergence. The total amount of N is dependent on soil type. When including a starter in the
fertilizer program,the recommended potassium and any additional phosphorus is normally broadcast at
planting. Plant samples can be analyzed during the growing season to monitor the overall nutrient status
of the corn. Timely management of weeds and insects are essential for corn production.
The following crop note applies to field(s): 3
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 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 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.

companies to select a high yielding variety with the characteristics needed for your area and conditions.
Plant 2-4 seed/row foot for 7-8" drills; 4-6 seed/row foot for 15" rows; 6-8 seed/row foot for 30"rows
and 8-10 seed/row foot for 36" rows. Increase the seeding rate by at least 10%for no-till planting.
Seeding depth should be 1-1 1/2" and adequate depth control is essential. Phosphorus and potash
recommended for the soybeans can be applied to the wheat in the Fall. For soils such as-------phosphorus
should be applied at planting as phosphorus will leach from these soils. Soybeans produce their own
nitrogen and are normally grown without additions of nitrogen. However, applications of 20-301bs/acre
N are sometimes made at planting to promote early growth and vigor. Tissue samples can be analyzed
during the growing season to monitor the overall nutrient status of the soybeans. Timely management of
weeds and insects is essential for profitable double crop soybean production.

OPERATION & MAINTENANCE PLAN
Proper lagoon 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 a
thunderstorm season in the summertime. This means that at the first sign of plant growth in the
later winter / early spring, irrigation according to a farm waste management plan should be done
whenever the land in 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 irrigated 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 fertilized 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
2

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 or 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 of 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
3

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 overflow 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 occur 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 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 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.
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 level. (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.
• Don not pump the lagoon liquid level lower than 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:
5

• 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
phosphors, 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 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.
