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. 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
This waste utilization plan, if carded out, meets the requirements for compliance with 15A NCAC

This plan does not include commercial fertilizer. The farm should produce adequate plant
available nitrogen to satisfy the requirements of the crops listed above.
The applicator is cautioned that P and K may be over applied while meeting the N requirements.
In the future, regulations may require farmers in some parts of North Carolina to have a nutrient
management plan that addresses all nutrients. This plan only addresses nitrogen.
In interplanted fields ( i.e. small grain, etc, interseeded in bermuda), 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 reach maturity, especially late in the season (Le.
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 the
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 cut to a height of
about two inches before drilling for best results.

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 3329.28 pounds of plant available nitrogen per year and will accumulate in the lagoon
sludge based on the rates of accumulation listed above.
If you remove the sludge every 5 years, you will have approximately 16646.4 pounds of plant
available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 55 acreas of land. If you apply the sludge
to com at a rate of 125 pounds per acre, you will need 133.1712 acres of land. Please note that these
are only estimates of the PAN produced and the land required to utilize that PAN. Actual values
may only be determined by sampling the sludge for plant available nitrogen content prior to application
Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific
application fields designated for sludge application at time of removal.
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 the preceding table. Failure to apply the recommended rates and
amounts of nitrogen shown in the tables may make this plan invalid.
*This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. In many situations, the application
amount shown cannot be applied because of the nitrogen limitation. The maximum
application amount shown can be applied under optimum soil conditions.
Your facility is designed for >180 days of temporary storage and the temporary storage must
be removed on the average of once every 6 months. In no instance should the volume of the
waste 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 the tables. 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 prior to applying the waste.

Additional Comments:
This NUP has been revised to reflect new production rates and RYE's as shown
on the NCSU website. The optional fields show that the producer may plant
vegetable crops in which application must be made 30 days preplant to planting.
Small grain cover must be removed by either grazing or cutting for hay.
Bermuda Combination graze and hay, 1/2 of the yield produced must be removed
with haying practices.
This NUP revision removes the 18.75 acre field that was in the previous plan per
a lease agreement with LD Porter.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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.
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 Utilization Plan
when there is a change in the operation, increase in the number of animals, method of
application, recieving crop type, or available land.
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 Tess 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 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
8
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.
Animal waste shall not be applied to saturated soils, during rainfall events, or when the
surface is frozen.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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 than 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 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.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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, Teaks 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 soil 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 a
minimum of five years.
23 Dead animals will be disposed of in a manner that meets North Carolina regulations.

Emergency Action Plan
Using this outline as guidance, you should develop a specific emergency action plan for your
waste handling system.. This plan will be implemented in the event that wastes from your
operation are leaking, overflowing, or running off the site. You should NOT wait until wastes
reach surface water 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 available to all
employees at the facility, as accidents, leaks, and breaks could happen at any time. Your
plan should follow this format:
1. Stop the release of wastes. Depending on the situation, this may or may not be
possible. Suggested responses to problems are listed below:
A. Lagoon overflow —possible solutions are:
add soil to berm to temporarily increase elevation of dam —any permanent
alteration of the darn should be approved by a qualified professional engineer
or qualified technical specialist
pump wastes to field at an acceptable rate
stop all additional flow to the lagoon (waters) --hold waste in house if possible
call a pumping contractor
• make sure no surface water is entering lagoon
NOTE: The above listed activities should be started when your lagoon level has exceeded
the temporary storage level.
B. Runoff from waste application field —actions include:
. immediately stop waste application
. create a temporary diversion or berm to contain the waste on the field
. incorporate waste to reduce further runoff
C. Leakage from the waste distribution system:
pipes and sprinklers —actions include:
— stop recycle (flushing system) pump
stop irrigation pump
close valves to eliminate further discharge
— separate pipes to create an air gap and stop flow
flush system, houses, solids separators —actions include: �� � ��
— stop recycle (flushing system) pump WOWQuaIV
— stop irrigation pump Aw,®na1Opera+ ,"�, .e
— make sure no siphon effect has been created
— separate pipes to create an air gap and stop flow
D. Leakage from base or sidewall of lagoon. Often these are seepage as opposed to
flowing leaks —possible action*:
. dig a small well or ditch to catch all seepage,put in a submersible
pump, and pump back into lagoon
if holes are caused by burrowing animals, trap or remove animals and
fill holes and compact with a clayey soil
. other holes may be likewise temporarily plugged with clay soil

Mortality Management Methods
Indicate which method(s) will be implemented.
When selecting multiple methods indicate a primary versus secondary option.
Methods other than those listed must be approved by the State Veterinarian.
Routine Mortality
1°. 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.
El [J 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.
in
.�
ElEl Complete incineration according to 02 NCAC 52C .0102.
El El A composting system approved and permitted by the NC Department of Agriculture & Con-
sumer Services Veterinary Division (attach copy of permit). If compost is distributed off -farm,
additional requirements must be met and a permit is required from NC DEQ.
El El In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture & Consumer Services (G.S. 106-549.70).
El 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 dam.
Fescue or common bermudagrass are the most common vegetative
covers. The vegetation should be fertilized each year, if needed, to
maintain a vigorous stand. The amount of fertilizer applied should be
based on a soils test, but in the event that it is not practical to obtain
a soils test each year, the lagoon embankment and surrounding areas
should be fertilized with 800 pounds per acre of 10-10-10, or
equivalent.
Brush and trees on the embankment must be controlled. This may be
done by mowing, spraying, grazing, chopping, or a combination of
these practices. This should be done at least once a year and
possibly twice in years that weather conditions are favorable for
heavy vegetative growth.
NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter
the lagoon water. Such chemicals could harm the bacteria in the lagoon that are treating
the waste.
Maintenance inspections of the entire lagoon should be made during the initial filling of
the lagoon and at least monthly and after major rainfall and storm events. Items to be
checked should include, as a minimum, the following:
Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes ---look for
1. separation of joints
2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes

• Lagoon surface ---look for:
1. undesirable vegetative growth
2. floating or lodged debris
▪ Embankment ---look for:
1. settlement, cracking, or "jug" holes
2. side slope stability ---slumps or bulges
3. wet or damp areas on the back slope
4. erosion due to lack of vegetation or as a result of wave action
5. rodent damage
Larger lagoons may be subject to liner damage due to wave action caused by strong
winds. These waves can erode the lagoon sidewalls, thereby weakening the lagoon dam.
A good stand of vegetation will reduce the potential damage caused by wave action. If
wave action causes serious damage to a lagoon sidewall, baffles in the lagoon may be
used to reduce the wave impacts.
Any of these features could lead to erosion and weakening of the dam. If your lagoon has
any of these features, you should call an appropriate expert familiar with design and
construction of waste lagoons. You may need to provide a temporary fix if there is a threat*
of a waste discharge. However, a permanent solution should be reviewed by the
technical expert. Any digging into a lagoon dam with heavy equipment is a serious
undertaking with potentially serious consequences and should not be conducted unless
recommended by an appropriate technical expert.
Transfer Pumps ---check for proper operation of:
1. recycling pumps
2. irrigation pumps
Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding
noise, or a large amount of vibration, may indicate that the pump is in need or repair or
replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that you
are not completely "surprised" by equipment failure. You should perform your pumping
system maintenance at a time when your lagoon is at its low level. This will allow some
safety time should major repairs be required. Having a nearly full lagoon is not the time
to think about switching, repairing , or borrowing pumps. Probably, if your lagoon is full,
your neighbor's lagoon is full also. You should consider maintaining an inventory of spare
parts or pumps.
Surface water diversion features are designed to carry all surface
drainage waters (such as rainfall runoff, roof drainage, gutter outlets,
and parking lot runoff) away from your lagoon and other waste
treatment or storage structures. The only water that should be
coming from your lagoon is that which comes from your flushing
(washing) system pipes and the rainfall that hits the lagoon directly.
You should inspect your diversion system for the following:
1. adequate vegetation
2. diversion capacity
3. ridge berm height

Identified problems should be corrected promptly. It is advisable to inspect your system
during or immediately following a heavy rain. If technical assistance is needed to
determine proper solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then
record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will
give you an idea of how much your lagoon level will rise with a certain rainfall amount
(you must also be recording your rainfall for this to work). Knowing this should help in
planning irrigation applications and storage. If your lagoon rises excessively, you may
have an inflow problem from a surface water diversion or there may be seepage into the
lagoon from the surrounding land.
Lagoon Operation
Startup:
1. Immediately after construction establish a complete sod cover on bare soil
surfaces to avoid erosion.
2. Fill new lagoon design treatment volume at least half full of water before
waste loading begins, taking care not to erode lining or.bank slopes.
3. Drainpipes into the lagoon should have a flexible pipe extender on the
end of the pipe to discharge near the bottom of the lagoon during initial
filling or another means of slowing the incoming water to avoid erosion of
the lining.
4. When possible, begin loading new lagoons in the spring to maximize
bacterial establishment (due to warmer weather).
5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon
liquid volume. This seeding should occour at least two weeks prior to the
addition of wastewater.
6. Maintain a periodic check on the lagoon liquid pH. If the pH falls below
7.0, add agricultural lime at the rate of 1 pound per 1000 cubic feet of
lagoon liquid volume until the pH rises above 7.0. Optimum lagoon liquid
pH is between 7.5 and 8.0.
7. A dark color, lack of bubbling, and excessive odor signals inadequate
biological activity. Consultation with a technical specialist is recommended
if these conditions occur for prolonged periods, especially during the warm
season.
Loading:
The more frequently and regularly that wastewater is added to a lagoon, the better the
lagoon will function. Flush systems that wash waste into the lagoon several times daily are
optimum for treatment. Pit recharge systems, in which one or more buildings are drained
and recharged each day, also work well.

Management:
•
Practice water conservation ---minimize building water usage and
spillage from leaking waterers, broken pipes and washdown through
proper maintenance and water conservation.
Minimize feed wastage and spillage by keeping feeders adjusted. This
will reduce the amount of solids entering the lagoon
Maintain lagoon liquid level between the permanent storage level and
the full temporary storage level.
Place visible markers or stakes on the lagoon bank to show the
minimum liquid. level and the maximum liquid lever (Figure 2-1).
Start irrigating at the earliest possible date in the spring based on
nutrient requirements and soil moisture so that temporary storage
will be maximized for the summer thunderstorm season. Similarly,
irrigate in the late summer/early fall to provide maximum lagoon
storage for the -winter.
The lagoon liquid 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.
