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 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.
1 of 11
This Ian is based on the waste application p pp cation 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 production.
This waste utilization plan,if carried out,meets the requirements for compliance with 15A NCAC
2H .0217 adopted by the Environmental Management Commission.

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 (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 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 766.8 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 3834 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 12 acreas of land. If you apply the sludge
to corn at a rate of 125 pounds per acre,you will need 30.672 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.

This NUP reflects a conversion of the facility from a 2420 feeder to finish to a
2840 wean to finish operation with no increase in SSLW. No crop changes
have been made but soil types were corrected and the"wettable acres"
footprint(prepared by Billy Houston)was updated to reflect 100'setback from
wells. This upadate changed the acres of pulls 1 b, 2b and 3a.

NUTRIENT 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 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.
3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic
crop yields based upon soil type, available moisture, historical data, climatic conditions,
and level of management, unless there are regulations that restrict the rate of applications
for other nutrients.
4 Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land eroding at more than 5 tons per acre per year but less than 10 tons
per acre per year provided grass filter strips are installed where runoff leaves the field
(See USDA, NRCS Field Office Technical Guide Standard 393 - Filter Strips).
5 Odors can be reduced by injecting the waste or disking after waste application. Waste
should not be applied when there is danger of drift from the land application field.
6 When animal waste is to be applied on acres subject to flooding, waste will be soil
incorporated on conventionally tilled cropland. When waste is applied to conservation tilled
crops or grassland, the waste may be broadcast provided the application does not occur
during a season prone to flooding (See "Weather and Climate in North Carolina" for
guidance).
7 Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that runoff
does not occur offsite or to surface waters and in a method which does not cause drift
from the site during application. No ponding should occur in order to control odor and
flies.
8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the
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, leaks and spills. A regular maintenance checklist should be kept on site.
20 Animal waste can be used in a rotation that includes vegetables and other crops for direct human
consumption. However, if animal waste is used on crops for direct human consumption, it should
only be applied pre-plant with no further applications of animal waste during the crop season.
21 Highly visible markers shall be installed to mark the top and bottom elevations of the temporary
storage (pumping volume) of all waste treatment lagoons. Pumping shall be managed to
maintain the liquid level between the markers. A marker will be required to mark the maximum
storage volume for waste storage ponds.
22 Waste shall be tested within 60 days of utilization and soil shall be tested at least annually at crop
sites where waste products are applied. Nitrogen shall be the rate-determining nutrient, unless
other restrictions require waste to be applied based on other nutrients, resulting in a lower
application rate than a nitrogen based rate. Zinc and copper levels in the 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.

SUBJECT: RETROFIT OF ELTON AND CHARLES ATKINSON WASTE TREATMENT
LAGOON — DUPLIN COUNTY SEPTEMBER 18 , 1995
THE DESIGN PACKAGE INCLUDES SEVERAL SETS OF COMPUTATIONS USED TO
DETERMINE THE TOTAL CAPACITY OF THE PROPOSED NEW LAGOONS. A. SET
OF COMPUTATIONS ALSO GIVES THE TOTAL CAPACITY TO INCLUDF. THE NEW
LAGOONS AND THE OLD LAGOON WITH IMPROVEMENTS. LISTED BELOW ARE
SEVERAL ITEMS FOUND IN THE DESIGN PACKAGE:
TOTAL CAPACITY OF NE4 LAGOONS — 460, 242 CUBIC FEET
TOTAL EXCAVATION OF NEW LAGOONS 13 , 358 CUBIC YARDS
TOTAL FILL FOR NEW LAGOONS — 5, 219 CUBIC YARDS
TOTAL CAPACITY OF NEW AND
UPGRADED LAGOONS — 680, 427 CUBIC FEET
BASED UPON THE ATTACHED DESIGN, THE NEW LAGOONS HAVE THE WASTE
TREATMENT CAPACITY FOR 2315 FINISHING ANIMALS. THE CURRENT
AVERAGE POPULATION IS FOR 2420 HEAD FINISHING. THE DESIGN
SECTION AT CARROLL'S FEELS THAT THE HERD DOES NOT NEED TO BE
REDUCED IF MR. ATKINSON FULLY IMPLEMENTS THE WASTE MANAGEMENT
PLAN.
AFTER COMPLETION OF THE NEW LAGOONS, SLUDGE MATERIAL WILL BE
REMOVED AND APPLIED TO GROWING CROPS IN AN AGRONOMIC MANNER. THE
OLD LAGOONS WILL BE RESHAPED AND UTILIZED FOR TREATMENT AND
TRANSPORT OF WASTE TO NEW LAGOONS.

IMPORTANT INFORMATION
ABOUT_LAGOON CONSTRUCTION
LISTED BELOW IS A BRIEF SUMMARY OF VOLUMES AND OTHER
DATA:(SEE CONTENTS OF PLAN FOR MORE INFORMATION)
EXCAVATION 13358--- cubic yards
FILL (pad & dike) 5219--- cubic yards
TOP SOIL (minimum 3" thick) 296--- cubic yards
CLAY LINER (represents a complete liner) --- cubic yards
Constructed top of dam must include a minimum of 5% settlement -
EXAMPLE: 10 feet high dam will require 5% of 10 feet or 0. 5 feet
fill above planned top of dam.
Clay content, thickness and compaction of liners (if required) are
very important. If the certifying technical specialist is unable
to approve the liner with normal field techniques, an independent
engineering analysis will be required (see CONSTRUCTION
SPECIFICATIONS for additional information) . If an independent
engineering analysis is required, this expense will be the
responsibility of the owner/grower.
Special attention needs to be given to the seeding specifications.
The lagoon dike must be. seeded according to specifications before
the system can be certified and stocked with animals. (Consult
with your NRCS Conservationist regarding mulching)

INSTRUCTIONS
All dams built with technical assistance from the Soil Conservation Service
must have a hazard classification assigned by the person responsible for
approving the design. Most farm ponds, except in borderline cases, can
be classified after a complete field investigation without assuming failure
and making breach studies. This data sheet is to be used for recording
the information obtained through field studies and for documenting the
hazard classification. Where there is a possibility for loss of life or
major property damage from a dam failure, an approved breach routing
procedure is to be used. (Consult with the area engineer. )
Hazard classifications of dams are made by evaluating the possibility
for loss of life and the extent of damage that would result if the dam
should suddenly breach--that is--a section of the dam be suddenly and
completely washed out. It is to be assumed that a wall of water will be
released equal to the height of the dam. This flood wave will be reduced
in height as it moves down the flood plain. The wave height (depth of
flooding) should be evaluated for a sufficient distance downstream until
the estimated flood level will not cause significant damage to improvements,
such as homes , buildings, roads, utilities, reservoirs, etc. The breach
flood level will be reduced depending oo the valley storage, slope, and
openers of the flood plain; however, in a narrow steep valley slopes
steeper than 10% should be given special consideration. One method of
evaluation is to compare available valley storage (under flood conditions)
to impoundment storage (figured to the top of the dam) for each reach
evaluated with a judgment estimate made of the flood wave height at all
critical points downstream.
Should there be any questions about the hazard classification for a dam,
the area engineer should be consulted before making design commitments.

System Calibration
Information presented in manufacturer's charts are based on average operation
conditions with relatively new equipment. Discharge rates and application rates
change over time as equipment gets older and components wear. In particular,
pump wear tends to reduce operating pressure and flow. With continued use,
nozzle wear results in an increase in the nozzle opening which will increase the
discharge rate while decreasing the wetted diameter.
You should be aware that operating the system differently than assumed in the
design will alter the application rate, diameter of coverage, and subsequently the
application uniformity. For example, operating the system with excessive pressure
resinrs in smaller droplets, greater potential for drift, and accelerates wear of the
sprinkler nozzle. Clogging of nozzles can result in pressure increase. Plugged
intakes or crvstallization of mainlines will reduce operating pressure. Operating
belc:•,v design pressure greatly reduces the coverage diameter and application
uniformity.
For the above reason, you should calibrate your equipment on a regular basis to
ensure proper application rates and uniformity. Calibration at least once every
three years is recommended. Calibration involves collecting and measuring flow at
several locations in the application area. Any number of containers can be used to
collect flow and determine the application rate. Rain gauges work best because
they already have a graduated scal.e from which to read the application amount
without having to perform additional calculations. However, pans, plastic buckets,
jars, or anything with a uniform opening and cross=section can be used provided
the liquid collected can be easily transferred to a scaled container for measuring.
For stationary sprinklers, collection containers should be located randomly
throughout the application area at several distances-from sprinklers. For traveling
guns, sprinklers should be located along a transect perpendicular to the direction of
pull. Set out collection containers 25 feet apart along the transect on both sides of
the gun cart. You should compute the average application rate for all
nonuniformity of the application. On a windless day, variation between containers
of more than 30 percent is cause for concern. You should contact your irrigation
dealer or technical specialist for assistance.

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 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 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 dam should be approved by a
qualified technical specialist
pump wastes to field at an acceptable rate
stop all additional flow to tl.e' lagoon (waterers)—hold waste in
house if possible
call a pumping contractor
make sure no surface water is entering lagoon
NOTE: These 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 systerp, houses, solids separators—actions include:
— stop recycle (flushing system) pump
— stop irrigation pump
— 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 clay type soil
other holes may be likewise temporarily plugged with clay soil
*Lagoon problems require the consultation of an individual
experienced in the design and installation of lagoons for permanent
repair measures.
2. Assess the extent of the spill and note any obvious damages.
a. Did the waste reach any surface waters?
b. Approximately how much was released and for what duration?
C. Any damage notes, such as employee injury,fish kills, or property
damage?
3. Contact appropriate agencies.
a. During normal business hours, call your DEM regional office, at
910-395-3900, after hours, emergency number: 919-733-3942.
Your phone call should include: your name, facility, telephone
number, the details of incident from item 2 above, the exact
location of the facility, and the location or
direction of movement of the spill, weather and wind
conditions, what corrective measures have been under taken,
and the seriousness of the situation.
b. If Spill leaves, or is likely to leave, property or enters surface
waters, call local emergency management servi..es (EMS) at 910-296-
2160.
C. Instruct ENAS to contact local Health Department.
d. Contact local Soil and Water Conservation District
Natural Resources Conservation Service office at 910-296-2121,
and Cooperative Extension Service at 910-296-2143for
advice/technical assistance.
e. If you are a contract swine grower associated with a swine company
integrator, contact the company representative.
4. Implement procedures as advised by DEM and technical assistance
agencies to rectify the damage, repair the system, and reassess the
waste management plan to keep problems with release of wastes from
happening again.

Emergency Action Plan
This plan will be implemented in the event that wastes from your operations are leaking, overflowing, or
running off the 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 available to all employees at the facility, as accidents, leaks, and breaks can happen at any
time.
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:
e add soil to the berm to increase the elevation of the dam
® pump wastes to fields at an acceptable rate
e stop all additional flow to the lagoon (waterers)
• call a pumping contractor
• make sure no surface water is entering the lagoon
Note: These activities should be started when your lagoon level has exceeded the temporary storage level.
b) Runoff from waste application field:
• immediately stop waste application
• create a temporary diversion or berm to contain the waste on the field
• incorporate waste to reduce further runoff
c) Leaking from the waste distribution system:
• pipes and sprinklers:
10 stop recycle (flushing system) pump
Oa stop irrigation pump
OO close valves to eliminate further discharge
® separate pipes to create an air gap and stop flow
• flush system, houses, solids separators:
C stop recycle (flushing system) pump
Q stop irrigation pump
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 the lagoon. Often these are seepage as opposed to flowing
leaks:
• dig a small well or ditch to catch all seepage, put in a submersible pump, and pump back
into the lagoon
OPERATION & MAINTENANCE PLAN
ear-round priority. It is especially
Proper lagoon liquid management should be a y p y p y
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 lire at the rate of 1 pound per t000 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.ether 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.

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
unddrtaking 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 rumps
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
