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
beefore each application cycle_ Annual sod 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. Akvways 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 fitter 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 DWR regulations.
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 fn thte fidine. you need to revise this plan. Nutrient -levels for different appbcabon
methods aretidthe same.
The estimated acres needed to apply the animal waste is based on typical nutrient content
for On type of facility- to some cases you may ward to have plant analysis made. which could
allow additional waste to be apple& Pmvisiions shag be made for the area receiving waste to
be flexible so as to accommodate charging waste analysis content and crop type Lime must
be applied to maintain pH in the optimum range for speciFic crop produdiorr.

This plan does not include commercial fertilizer_ The farm should produce adequate plant
available nitrogen to satisfy the requirements ofthe crops fisted above.
The applicator is cautioned that R and K may be over applied whoa 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 as nutrients. This {clan only addresses nitrogen
In interplanted fief ( i.e_ small grain, etc, interseeded in bermuda), forage must be removed
through grazing, hay, andlor 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.
Aprilor May). Shading may result if small grain gets too high and this will definitely interfere
with stand of bermudiagrass_ 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 interplantsmall grain, etc, is tate September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or dmtto a height of
about two inches before dulling 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 2992 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 14960 pounds of plant
awe nib,ogen to uhfize. Assuming you applyy this PAN to hybrid berrnuda grass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 49 acreas of land. if you apply the sludge
to corn at a rate of 125 pounds per acre, you win need 119.68 acres -of land. Ptease 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 avalable nitrogen corftrd prior to action
Actual uublization 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 RiRIGATION:
The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation
such that runoff or pon&V occurs. This rate is limited by initial son 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 ghat an irrigation system is installed to property
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 marry 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 fadgiy 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_
tt is the responsbi ity of the producer and waste applicator to ensure that the spreader equipment
is operated property 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.
Cal 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.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
f Animal waste shall not reach surface wags 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 Where 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
sloes 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
hirn/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 Phan when there is
a change in the operation, increase in the number of animals, method of application,
relieving 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, cfsrnatic conditions, and
level of management, unless there are regulations that restrict the fate 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 tiller strips are installed where nmff leaves the held (See
USDA, MRCS Feld 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 Whsen 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 ote 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. WasWnutrient 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
wad fldw than swine waste #curb 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 ewer -spraying. Animal waste may -be applied to -prfor-comterted cropland fsro Aded the Rids
have been approved as a land application site by a "technical specialise. 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.
1-6 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
str+ec tares should be inspected regularly for evidence of erosion, leakage, or 4diischarge.
18 if animal production at the facility is to be suspended or terminated, the owner is responsible for
-obtaining and implementing a "cdosure plan" which will eH minute the possibility of an illegal
discharge, pollution and erasion.
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 rather crops for direct human
consumption. However, if animal waste is used on crops for direct human consumption, it should
only be applied pre -cant with no further applications of animal waste during thect-op 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.
72 Waste shall be tested within 60 days of utilization and soil shall be tested at least annually at crop
sites where waste pr-oducts are applied. Nitrogen shall be the Tate --determining nutrient, unless
other restrictions require waste to be applied based on ether nutrients, resulting in a lower
application rate than a nitrogen based rate. Zinc and copper levels in the soil shall be monitored
and alternative +gyp 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 aminirnurn 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 bead animals will be disposed of in a manner that meets North Carolina regulations.

This plan will be implemented in the event that wastes from your operation are leaking,
overflowing or running off site. You should not wait until wastes reach surface waters or
leave your property to consider that you have a problem. You should make every effort to
ensure that this does not happen. This plan should be posted in an accessible location
for all employees at the facility. The following are some action items you should take.
1. Stop the release of wastes. Depending on the situation, this may or may not be possible. Suggested
responses to some possible problems are listed below.
A. Lagoon overflow - possiblesolutions are:
a)
Add soil to berm to increase elevation of dam.
b)
Pump wastes to fields at an acceptable rate.
c)
Stop all flow to the lagoon immediately.
d)
Call a pumping contractor.
e)
Make sure no surface water is entering lagoon.
B. Runoff
from waste application field -actions include:
a)
Immediately stop waste application.
b)
Create a temporary diversion to contain waste.
c)
Incorporate waste to reduce runoff.
d)

d)
Repair all leaks prior to restarting pumps.
D. Leakage from flush systems, houses, solid separators - action include:
a)
Stop recycle pump.
b)
Stop irrigation pump.
c)
Make sure siphon occurs.
d)
Stop all flow in the house, flush systems, or solid separators.
E. Leakage from base or sidewall of lagoon. Often this is seepage as opposed to flowing leaks -
possible action:
a)
Dig a small sump or ditch from the embankment to catch all seepage, put in a submersible
pump, and pump back to lagoon.
b)
If holes are caused by burrowing animals, trap or remove animals and fill holes and
compact with a clay type soil.
c)
Have a professional evaluate the condition of the side walls and the lagoon bottom as soon
as possible.
2. Assess the extent of the spill and note any obvious damages.

Modality Management Methods q1_&
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
a Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal
death. The burial must be at least 300 feet from any flowing stream or public body of water
(G.S.106-403). The bottom of the burial pit should beat least one foot above the seasonal
high water table. Attach burial location map and plan.
NLandfill 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.
D 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.
In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture & Consumer Services (G.S. 106-549.70).
Any method which, in the professional opinion of the State Veterinarian, would make possible
the salvage of part of a dead animal's value without endangering human or animal health.
(Written approval by the State Veterinarian must be attached).
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 specked by the State
Veterinarian.
• Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary
Division regulations and guidance-
0 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 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 minimurrF 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
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
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.
Y
OPERATION AND MAINTENANCE PLAN
--------------------
This lagoon is designed for waste treatment with minimum odor
control. The time required for the planned fluid level to be
reached may vary due to soil conditions,flu hing operations, and
the amount of fresh waterladded to the syst m..
Land application of wastewater is recogniz d as an acceptable
method of disposal. Methods of applicationrinclude solid set,
center pivot, guns, and traveling gun irrigation. Care should be
taken when applying waste'to prevent runofflfrom the field or damage
to crops.
The following items are to be carried out: j
1. It is strongly recommended that the tre tment lagoon be pre -
charged to 1/2 its capacity to prevent excepsive odors during
start-up. Pre -charging reduces the concentration of the initial
waste entering the lagoonithereby reducing 'dors. Solids should be
covered with effluent at all times.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing -of waste (see Attachment B)
before land application.
3. Begin pump -out of the lagoon when fluid, level reaches eleva-
tion 51. 9 sere as marked by permanent'markers. Stop pump -out when
the fluid level reaches elevation449.720,=& of before fluid depth is
less than 6 feet deep (this prevents 'the loss of favorable
bacteria) .
4. The recommended maximum amount to apply per irrigation is
one (1) inch and the recommended maximum application rate is 0.4
inch per hour. l
S. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
6. Repair any eroded areas or areas damage' by rodents and
establish in vegetation.
7. All surface runoff is'to be diverted from the lagoon to stable
outlets.
