STORAGE STRUCTURE: Anaerobic Waste Treatment Lagoon
APPLICATION METHOD: Irrigation
The waste from your animal facility must be land applied at a
specified rate to prevent pollution of surface water and/or
groundwater. The plant nutrients in the animal waste should be used
to reduce the amount of commercial fertilizer required for the crops
in the fields where the waste is to be applied.
This waste utilization plan uses nitrogen as the limiting nutrient.
Waste should be analyzed before each application cycle. Annual soil
tests are strongly encouraged so that all plant nutrients can be
balanced for realistic yields of the crop to be grown.
Several factors are important in 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:
1. Always apply waste based on the needs of the crop to be
grown and the nutrient content of the waste. Do not apply
more nitrogen than the crop can utilize.
2. Soil types are important as they have different infiltration
rates, leaching potentials, cation exchange capacities, and
available water holding capacities.
3. Normally waste shall be applied to land eroding at less than
5 tons per acre per year. Waste may be applied to land
eroding at 5 or more tons per acre annually, but less than
10 tons per acre per year providing that adequate filter
strips are established.
4. Do not apply waste on saturated soils, when it is raining,
or when the surface is frozen. Either of these conditions
may result in runoff to surface waters which is not allowed
under DWQ regulations.
Page: 1

ANIMAL WASTE UTILIZATION PLAN
5. Wind conditions should also be considered to avoid drift and
downwind odor problems.
6. To maximize the value of the nutrients for crop production
and to reduce the potential for pollution, the waste should
be applied to a growing crop or applied not more than 30
days prior to planting a crop or forages breaking dormancy.
Injecting the waste or disking will conserve nutrients and
reduce odor problems.
This plan is based on the waste application method shown above. If
you choose to change methods in the future, you need to revise this
plan. Nutrient levels for different application methods are not the
same.
The estimated acres needed to apply the animal waste is based on
typical nutrient content for this type of facility. Acreage
requirements should be based on the waste analysis report from your
waste management facility. In some cases you may want to have plant
analysis made, which could allow additional waste to be applied.
Provisions shall be made for the area receiving waste to be flexible
so as to accommodate changing waste analysis content and crop type.
Lime must be applied to maintain pH in the optimum range for specific
crop production.
This waste utilization plan, if carried out, meets the requirements
for compliance with 15A NCAC 2H .0217 adopted by the Environmental
Management Commission.
AMOUNT OF WASTE PRODUCED PER YEAR (gallons, ft3, tons, etc.)
1990 hogs x 1.9 tons waste/hogs/year = 3781 tons
AMOUNT OF PLANT AVAILABLE NITROGEN (PAN) PRODUCED PER YEAR
1990 hogs x 2.3 lbs PAN/hogs/year = 4577 lbs. PAN/year
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.
The following acreage will be needed for waste application based on
the crop to be grown, soil type and surface application.

Indicates that this field is being overseeded (i.e. interplanted) or
winter annuals follow summer annuals.
In interplanted fields (i.e. small grain, etc, interseeded
in bermudagrass), forage must be removed through grazing,
hay and/or silage. Where grazing, plants should be grazed
when they reach a height of six to nine inches. Cattle
should be removed when plants are grazed to a height of four
inches. In fields where small grain, etc, is to be removed
for hay or silage, care should be exercised not to let small
grain to reach maturity, especially late in the season (i.e.
April or May). Shading may result if small grain gets too
high and this will definitely interfere with stand of
bermudagrass. This loss of stand will result in reduced
yields and less nitrogen being utilized. Rather than
cutting small grain for hay or silage just before heading as
is the normal situation, you are encouraged to cut the small
grain earlier. You may want to consider harvesting hay or
silage two to three times during the season, depending on
time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late
September or early October. Drilling is recommended over
broadcasting. Bermudagrass should be grazed or mowed to a
height of about two inches before drilling for best results.

ANIMAL WASTE UTILIZATION PLAN
*** This number must be less than or equal to 0 in order to fully
utilize the animal waste N produced.
Acres shown in each of the preceding tables are considered to be the
usable acres excluding required buffers, filter strips along ditches,
odd areas unable to be irrigated, and perimeter areas not receiving
full application rates due to equipment limitations. Actual total
acres in the fields listed may, and most likely will be, more than
the acres shown in the tables.
See attached map showing the fields to be used for the utilization of
animal waste.
SLUDGE APPLICATION:
The waste utilization plan must contain provisions for periodic land
application of sludge at agronomic rates. The sludge will be nutrient
rich and will require precautionary measures to prevent over application
of nutrients or other elements. Your production facility will produce
approximately 736.3 pounds of plant available nitrogen per year in the
sludge.
If you remove the sludge every 5 years, you will have approximately 3681.5
pounds of PAN to utilize. Assuming you apply this PAN to hybrid
bermudagrass hayland at the rate of 300 pounds of nitrogen per acre, you
will need 12.2716666667 acres of land. If you apply the sludge to corn at
the rate of 125 pounds of nitrogen per acre, you will need 29.452 acres
of land. Please be aware that these are only estimates of the PAN and
land needed. Actual requirements could vary by 25% depending on your
sludge waste analysis, soil types, realistic yields, and application
methods.
APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not exceed the intake rate of the
soil at the time of irrigation such that runoff or ponding occurs. This
rate is limited by initial soil moisture content, soil structure, soil
texture, water droplet size, and organic solids. The application amount
should not exceed the available water holding capacity of the soil at the
time of irrigation nor should the plant available nitrogen applied exceed
the nitrogen needs of the crop.
If surface irrigation is the method of land application for this plan,
it is the responsibility of the producer and irrigation designer to ensure
that an irrigation system is installed to properly irrigate the acres
shown in Tables 1 and 2. Failure to apply the recommended rates and

ANIMAL WASTE UTILIZATION PLAN
Your facility is designed for 100.00 days of temporary storage and
the temporary storage must be removed on the average of once every
3.33333333333 months. In no instance should the volume of the waste
be stored in your structure be within the 25 year 24 hour storm
storage or one foot of freeboard except in the event of the 25 year
24 hour storm.
It is the responsibility of the producer and waste applicator to
ensure that the spreader equipment is operated properly to apply the
correct rates to the acres shown in Tables 1 and 2. Failure to apply
the recommended rates and amounts of nitrogen shown in the tables may
make this plan invalid.
Call your technical specialist after you receive the waste analysis
report for assistance in determining the amount of waste per acre and
the proper application rate prior to applying the waste.
NARRATIVE OF OPERATION

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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 which 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 waste, he/she shall
provide a copy 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
facility to secure an update of the Waste Utilization Plan when
there is a change in the operation, increase in the number of
animals, method of utilization, or available land.
3. Animal waste shall be applied to meet, but not exceed, the
nitrogen needs for realistic crop yields based on soil type,
available moisture, historical data, climatic conditions, and
level of management, unless there are regulations that restrict
the rate of application 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 that is eroding
at 5 or more tons, but less than 10 tons per acre per year
providing grass filter strips are installed where runoff leaves
the field. (See FOTG Standard 393 -Filter Strip)
5. Odors can be reduced by injecting the waste or disking after
waste application. Waste should not be applied when there is
danger of drift from the irrigation field.
6. When animal waste is to be applied on acres subject to
flooding, it will be soil incorporated on conventionally tilled
cropland. When 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 or flies.
8. Animal waste shall not be applied to saturated soils, during
rainfall events, or when the 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.
Page: 9

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
10. Waste nutrients 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 from any perennial stream or river (other
than an irrigation ditch or canal. Animal waste other than
swine waste from facilities sited on or after October 1, 1995),
shall not be applied closer than 25 feet to perennial waters.
(See Standard 393 - Filter Strips).
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
they have been approved as a land application site by a
"technical specialist". Animal waste shall not be applied on
grassed waterways that discharges 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.
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.
Page: 10

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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 preplant 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
element. 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 for
optimum crop production and maintained. Soil and waste
analysis records shall be kept for five years. Poultry dry
waste application records shall be maintained for three (3)
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.

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
Buria! 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.
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.
I—i 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.
aIn 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).
Qa Any method which, in the professional opinion of the State Veterinarian, would make possible
the salvage of part of a dead animal's value without endangering human or animal health.
(Written approval by the State Veterinarian must be attached).
Mass Mortality Plan
Mass mortality plans are required for farms covered by an NPDES permit. These plans are
also recommended for all animal operations. This plan outlines farm -specific mortality man-
agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup-
ports a variety of emergency mortality disposal options; contact the Division for guidance.
• A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated
when numbers of dead animals exceed normal mortality rates as specified by the State
Veterinarian.
• Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary
Division regulations and guidance.
• Mass burial sites are subject to additional permit conditions (refer to facility's animal
waste management system permit).
• In, the event of imminent threat of a disease emergency, the State Veterinarian may enact
additional temporary procedures or measures for disposal according to G.S. 106-399.4.

OPERATION & MAINTENANCE PLAN
Proper lagoon liquid management should be a year-round priority. It is especially
important to manage levels so that you do not have problems during extended 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 darn.
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 Iagoon 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:
I. separation of joints
2. cracks or breaks
I 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 sidewalis, 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:
l . 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
� 3 2019
tQuft
1'Viont

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 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 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.
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 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.
