Primary secondary Routine Mortality
Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal
El 0 death. The burial must be at least 300 feel from any flowing stream or public body of water
(G.S.106-403). The bottom of the burial pit should be at least one feat above the seasonal
high water table.Attach burial location map and plan.
❑ Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC
13B.0200.
Rendering at a rendering plant licensed under G.S. 106-166.7.
Complete incineration according to 02 NCAC 52C .0102.
Q O A composting system approved and permitted 15y 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.
Q ❑ 1n 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).
❑ a Any method which,in the professional opinioniof the State Veterinarian,would make possible
the salvage of part of a dead animal's value vnthout endangering human or animal health.
(Written approval by the Stale 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 Jaccording to G.S. 106-399.4.

The waste from your animal facility must be land applied at a specified rate to prevent pollution of
surface 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 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 sage manner.
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. Soil types are important as they
have different infiltration rates, leaching potentials, cation exchanges capacities, and available
water holding capacities. Normally, waste shall not be applied to land eroding at greater than 5
tons per acre per year. With special precautions, waste may be applied to land eroding at up to 10
tons per acre per year. 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 DEM regulations. Wind conditions should also be considered to avoid drift and
downwind odor problems. To maximize the value of nutrients for crop production and to reduce
the potential for pollution, the waste should be applied to a growing crop or applied to bare
ground not more than 30 days prior to planting. Injecting the waste or disking will conserve
nutrients and reduce odor problems.
The estimated acres needed to apply the animal waste is based on typical nutrient content for this
type of facility. Acreage requirements should be based on the waste analysis report from your
waste management facility. Attached you will find information on proper sampling techniques,
preparation, and transfer of waste samples to the lab for analysis.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
2H.0217 adopted by the Environmental Management Commission.

- WASTE UTILIZATION PLA-,
REOIIIRED SPECIFICATIONS
1. Animal waste shall not reach surface waters of the state by
runoff, drift, manmade conveyances, direct application, or
direct discharge during operation or land application. Any
discharge of waste which reaches surface water is prohibited.
2. There must be documentation in the design folder that the
producer either owns or has an agreement for use of adequate
land on which to properly apply, the waste. If the producer does
not own adequate land to properly dispose of waste, he/she shall
provide a copy of an agreement with a landowner who is within a
reasonable proximity, allowing him/her the use of the land for
waste application. It is theresponsibility of the owner of the
facility to secure an update of the Waste Utilization Plan when
there is a change in the operation, increase in the number of
animals, method of utilization, or available land. .
3 . Animal waste shall be applied to meet, but not exceed, the
nitrogen needs for realistic crop yields based on soil type,
available moisture, historical data, climatic conditions, and
level of management, unless there are regulations that restrict
the rate of application for other nutrients .
� 4. Animal waste shall be applied to land eroding less than 5 tons
per acre per year. Waste may be applied to land that is eroding
at 5 or more tons, but less than 10 tons per acre per year
providing grass filter strips are installed where runoff leaves
the field. (See FOTG Standard 3*93 -Filter Strip)
5. Odors can be reduced by injecting the waste or disking after
waste application. Waste should not be applied when there is
danger of drift from the irrigation field.
6. When animal waste is to be applied on acres subject to
flooding, it will be soil incorporated on conventionally tilled
cropland. When applied to conservation tilled crops or
grassland, the waste may be broadcast provided the application
does not occur during a season prone to flooding. (See "Weather
and Climate in North Carolina" for guidance. )
7. Liquid waste shall be applied at rates not to exceed the soil
infiltration rate such that runoff does not occur offsite or to
surface waters and in a method which does not cause drift from
the site during application. No ponding should occur in order
to control odor or flies.
S . Animal waste shall not be applied to saturated soils, during
rainfall events, or when the surface is frozen.
9. Animal waste shall be applied on actively growing crops in such
a manner that the crop is not covered with waste to a depth that
would inhibit growth. The potential for salt damage from animal
waste should also be considered.
Page: 8

WASTE UTILIZATION PI
REQUIRED SPECIFICATIONS
10 . Waste nutrients shall not be applied in fall or winter for
spring planted crops on soils with a high potential for
leaching. Waste nutrient loading rates on these soils should be
held to a minimum and a suitable winter cover crop planted to
take up released nutrients. Waste shall not be applied more
than 30 days prior to planting of the crop or forages breaking
dormancy.
11. Any new swine facility sited on or after October 1, 1995 shall
comply with the following: The outer perimeter of the land area
onto which waste is applied from a lagoon that is a component of
a swine farm shall be at least 50 feet from any residential
property boundary and from any perennial stream or river (other
than an irrigation ditch or canal. Animal waste other than
swine waste from facilities sited on or after October 1, 1995) ,
shall not be applied closer than 25 feet to perennial waters.
(See Standard 393 - Filter Strips) .
12. Animal waste shall not be applied closer than 100 feet to
wells .
13 . Animal waste shall not be applied closer than 200 feet of
dwellings other than those owned by the landowner.
14. Waste shall be applied in a manner not to reach other property
and public right-of-ways.
15 . Animal waste shall not be discharged into surface waters,
drainageways, or wetlands by a discharge or by over-spraying.
Animal waste may be applied to prior converted cropland provided
they have been approved as a land application site by a
"technical specialist" . Animal waste shall not be applied on
grassed waterways that discharges directly inton water courses,
and on other grassed waterways, waste shall be applied at
agronomic rates in a manner that causes no runoff or drift from
the site. -
16. Domestic and industrial waste from washdown facilities,
showers, toilets, sinks, etc. , shall not be discharged into the
animal waste management system.
17. A protective cover of appropriate vegetation will be
established on all disturbed areas (lagoon embankments, berms,
pipe runs, etc . ) . Areas shall be fenced, as necessary, to
protect the vegetation. Vegetation such as trees, shrubs, and
other woody species, etc. , are limited to areas where considered
appropriate. Lagoon areas should be kept mowed and accessible.
Berms and structures should be inspected regularly for evidence
of erosion, leakage or discharge.

WASTE UTILIZATION PL.
REQUIRED SPECIFICATIONS
18. If animal production at the facility is to be suspended or
terminated, the owner is responsible for obtaining and
implementing a "closure plan" which will eliminate the
possibility of an illegal discharge, pollution and erosion.
19. Waste handling structures, piping, pumps, reels, etc . , should
be inspected on a regular basis to prevent breakdowns, leaks,
and spills . A regular maintenance checklist should be kept on
site.
20. Animal waste can be used in a rotation that includes vegetables
and other crops for direct human consumption. However, if
animal waste is used on crops for direct human consumption it
should only be applied preplant with no further applications of
animal waste during the crop season.
21. Highly visible markers shall be installed to mark the top and
bottom elevations of the temporary storage (pumping volume) of
all waste treatment lagoons. Pumping shall be managed to
maintain the liquid level between the markers . A marker will .
be required to mark the maximum storage volume for waste
storage ponds.
22. Waste shall be tested within 60 days of utilization and soil
shall be tested at least annually at crop sites where waste
products are applied. Nitrogen shall be the rate - determining
element. Zinc and copper levels in the soils shall be
monitored and alternative crop sites shall be used when thes
metals approach excessive levels. pH shall be adjusted for
optimum crop production and maintained. Soil and waste
analysis records shall be kept for five years. Poultry dry
waste application records shall be maintained for three (3)
years. Waste application records for all other waste shall be
maintained for five (5) years.
23. Dead animals will be disposed of in a manner that meets North
Carolina requlations.

DATE: 7,9b-
A visual inspection of the waste storage pond or lagoon will be performed
at least twice a year. The inspector should check the condition of the dam
and the emergency spillway. The inspector will need to look for signs if
slope failure and seepage on the back slope and the toe of the dam. Also, a
very close look will need to be made to check for signs of damage due to
varmint (ground hogs, muskrats, etc. ) burrows. A visual inspection should
be made after heavy rainfall events to ensure that the structure is not
experiencing erosion rills or gullies . Any problems found should be brought
to the attention of the technical specialist forrepair recommendations .
The waste storage pond or lagoon will need to be mowed twice a year. All
eroded areas shall be repaired and stabilized. Areas that do not have an
adequate ground cover shall be reseeded to provide a vegetative cover
sufficient to restrain erosion. the dam and all constructed slopes will
need to be fertilized annually with 500 pounds of 10-10-10 per acre or
equivalent.
A permanent waste storage pond or lagoon marker will be established and
maintained in the waste pool . The maximum liquid level marker should not
exceed elevation 4M Sf.�'f" ,., " . Daily lagoon level records should be kept
ft
on an appropriate form.
Maintain all waste handling equipment in accordance with manufacturer' s
specifications.
All waste application shall be completed in accordance with the waste
utilization plan. The waste storage pond or lagoon will be pumped at the
end of each design storage period (20 days or (p months) or as
needed due to excess rainfall .
All surface runoff is to be diverted from the lagoon to stable outlets .

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-possible solutions are:
1) Add soil to berm to increase elevation of dam.
2) Pump wastes to fields at an acceptable rate.
3) Stop all flows to the lagoon immediately.
4) Call a pumping contractor.
5) Make sure no surface water is entering lagoon.
b. Runoff from waste application field-actions include:
1) Immediately stop waste application.
2) Create a temporary diversion to contain waste.
3) Incorporate waste to reduce runoff.
4) Evaluate and eliminate the reasons) that caused the runoff.
5) Evaluate the application rates for the fields where runoff occurred.

OPERATION & MAINTENANCE PLAN
Proper lagoon management should be a year-round priority. It is especially important to manage
levels so that you do not have problems during extended rainy and wet periods.
Maximum storage capacity should be available in the lagoon for periods when the receiving crop is
dormant (such as wintertime for bermudagrass)or when there are extended rainy spells such as a
thunderstorm season in the summertime. This means that at the first sign of plant growth in the
later winter / early spring, irrigation according to a farm waste management plan should be done
whenever the land in dry enough to receive lagoon liquid. This will make storage space available
in the lagoon for future wet periods. In the late summer/ early fall the lagoon should be pumped
down to the low marker (see Figure 2-1)to allow for winter storage. Every effort should be made
to maintain the lagoon close to the minimum liquid level as long as the weather and waste
utilization plan will allow it.
Waiting until the lagoon has reached its maximum storage capacity before starting to irrigated does
not leave room for storing excess water during extended wet periods. Overflow from the lagoon for
any reason except a 25-year, 24-hour storm is a violation of state law and subject to penalty
action.
The routine maintenance of a lagoon involves the following:
• Maintenance of a vegetative cover for the dam. Fescue or common bermudagrass
are the most common vegetative covers. The vegetation should be fertilized each
year, if needed, to maintain a vigorous stand. The amount of fertilized applied
should be based on a soils test, but in the event that it is not practical to obtain a
soils test each year, the lagoon embankment and surrounding areas should be
fertilized with 800 pounds per acre of 10-10-10, or equivalent.
• Brush and trees on the embankment must be controlled. This may be done by
mowing, spraying, grazing, chopping, or a combination of these practices. This
should be done at least once a year and possibly twice in years that weather
conditions are favorable for heavy vegetative growth.
NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter the
lagoon water. Such chemicals could harm the bacteria in the lagoon that are treating the waste.
Maintenance inspections of the entire lagoon should be made during the initial filling of the lagoon
and at least monthly and after major rainfall and storm events. Items to be checked should
include, as a minimum, the following:
Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes --look for:
1. separation of joints
2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes

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 at/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:
4

• 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.
4

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.

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 results 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 crystallization of
mainlines will reduce operating pressure. Operating below 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 scale 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.

acres of land.Cleared trees and brush shall be placed in wind-rows perpendicular to the slope and
down slope from the soil disturbance areas in order to assist in sediment and erosion control.
3. D. Buildings And Structures
There are no existing buildings or structures inside the proposed lagoon construction site. There
are no known utilities above or below grade within the proposed construction site. New animal
waste treatment lagoons should be located as far as possible from residences, places of business,
or places of public gathering but in no case closer than 750 feet from same. The farm meets this
criteria. There are no water wells within 100 feet of this proposed lagoon site and none are planed
to be installed closer than 100 feet. Wells are recommended to be at least 300 feet from the
lagoon when possible. No future building or improvements are planed down slope from the
lagoon.The lagoon is at least 100 feet from the property boundary.
3. E. Adjacent Property Near The Proposed Construction Site
As mentioned above,the farm under study has been used for agriculture and is in a rural setting.
Exhibits 2 and 3 show some property features.The following is a general description of the land
adjoining or near the proposed lagoon site.
All Sides--Wooded area except what has been cleared for future pasture land.
There are no dwellings,structures,roads,or bridges between the proposed lagoon site and the
nearest creek or branch. No towns or municipalifies are known to get their water from nearby
streams which would be impacted immediately by a dam breach.From a structures and
environmental standpoint,the engineer thinks this lagoon should be classified as low hazard.

treatment lagoons are designed to both store and treat the wastes from many types of animal
confinement operations (usually for wastes in a liquid or slurry form). These lagoons rely on
bacteria to decompose the organic matter in the wastewater into gases, liquids, and sludges or
solids. In addition significant pathogen reduction is achieved by the process. Two types of
lagoons that are sometimes used in wastewater treatment are aerobic and anaerobic lagoons.
Both aerobic and anaerobic type lagoons are effective in treating animal wastes, however the most
common type of lagoon in use for the treatment of swine effluent is the anaerobic type lagoon. An
anaerobic lagoon system is being designed for the Johnson Farm. Further discussions within this
report will be confined to the anaerobic lagoon design process.
Anaerobic lagoons develop bacteria populations which thrive without the presence of oxygen.
These lagoons usually contain considerably more volume than aerobic lagoons and are normally
deeper. Anaerobic lagoons are well suited for high strength wastewaters such as swine manure.
The anaerobic process decomposes more organic matter per unit volume than does the aerobic
process and is a good method of pathogen reduction. Since anaerobic lagoons are not
mechanically aerated they do not consume electrical power and are generally low maintenance,as
compared to the aerobic lagoon. If properly constructed and maintained anaerobic lagoons offer
very good effluent treatment and positive odor controls.
Sudden changes in nutrient loadings or changes in atmospheric temperature can cause a
disruption in the anaerobic microbial process,often resulting in periods of odorous gases being
released. Upsets due to changes in weather for instance are normally short lived provided there
has not been a severe bacteria population reduction. Anaerobic lagoons in warmer climates do
not tend to suffer the severe seasonal problems that colder climates report.
Lagoon design documents and research reports often give numbers related to the design process.
These numbers vary depending on which publication is reviewed. One fact remains constant
throughout literature;Farm Management Has As Much To Do With Odor Minimization As Does
Proper Lagoon Designl However since teaching proper farm management(including proper
waste management)is beyond the scope of this document, discussion on physical lagoon design
criteria will be the emphasis presented below. The engineer has used design data accepted and
used by the N.C. Cooperative Extension Service at NCSU for basic design parameters;as well as
design data accepted and used by the U.S.SCS.
4. C. Lagoon Shape
There is no one special shape required for the design of anaerobic lagoons. However due to
construction ease most lagoons(especially in the coastal plain of North Carolina)are rectangular
in overall shape with a trapezoidal cross section. Lagoons in the Piedmont are often less uniform
in shape due to depth-to-rock. Flat or nearly flat bottoms are also desirable but not a requirement.
One will find many shapes of anaerobic lagoons functioning well. Lagoon volume is a more
important criteria than is shape. Very Shallow water depths are discouraged.
For brevity reasons,all of the calculations associated with estimating lagoon volumes will not be
presented in this document. However Important design values are presented below.
Page 6

fI Phase 1 January 10, 1995
I The primary lagoon at this site is being designed with a square surface and flat bottom. A synthetic
liner is being recommended. It will have a trapezoidal cross section with an interior slope of 3:1 or
fsteeper.
Most good clay soils will allow side slopes in lagoon construction to be made 1:1, 2:1,3:1 or less
steep however there is some soil stability disadvantage to side slopes of 1:1,thus seldom is a 1:1
side slope used. The interior sides of this lagoon was chosen to be made 3:1 because of the
selected contractor's earth moving equipment limitations. Outside slopes of earthen berms or
dams should not exceed 3:1 so regular maintenance and mowing can be conducted. Outside
slopes of 4:1 or greater are acceptable provided the height of the dam in reference to the toe is
less than 15 feet. Dams above 16 feet require special permitting and must meet additional dam
safety criteria.
4. D. Sludge Holding Capacity
A common practice of the modern swine producer is to waste or irrigate sludge when land
application events occur.This is usually done by first agitating the lagoon effluent to mix up the
solids and the liquids. This practice helps prevent sludge accumulation on the lagoon floor. Sludge
irrigation is a management decision and does not tend to greatly increase the amount of
objectionable odors if done regularly and under the more desirable weather conditions.
Mr.Johnson wishes to agitate his lagoon on occasion and irrigate the solids along with the liquid.
Based on this decision to routinely irrigate solids the sludge accumulation for this design is
considered almost zero. However approximately 5,300 cubic feet(39,638 gallons)of sludge was
allowed for this design for safety purposes.
4. E. Design Treatment Volume
The design treatment volume(sometimes called Minimum Design Volume)is the volume of
wastewater needed to maintain optimum conditions for bacterial growth. This volume may require
several months to obtain once filling begins. The owner should be careful to add water to the
lagoon until one third to one half of the design treatment volume is achieved before adding swine
manure.
The operator should always strive to maintain a liquid depth of at least 6 feet to control excessive
odors. Initial water addition to the lagoon can be from on-site water wells,creek water pumped into
the lagoon or from intentionally diverted rainfall run-off. Mr.Johnson plans to use well water to
initially charge his lagoon.
There are some differences of opinion on the amount of volume necessary to achieve adequate
odor control in anaerobic lagoons. Conventional practice says bigger is better,and there are
several reported benefits to designing a large treatment volume. For instance,the extra water
offers dilution to the swine manure at first,giving the operator a little more treatment buffer in the
early year(s)of the lagoon's life. Concentrations of nutrients will eventually increase to a steady
state in both extra large lagoons and adequately sized lagoons.
Researchers at NCSU have conducted field work on hundreds of lagoons and seen many types of
operations. The general consensus is that lagoon management makes more difference than size
in minimizing lagoon odors,provided that the lagoon is not grossly undersized. Even lagoons of
Page 7

' Phase I January 10, 1995
very large size can produce abnormal amounts of odor if improperly managed. The U.S. Soil
Conservation Service in North Carolina uses research data developed at NCSU for designing
anerobic swine effluent lagoons,Through out this document the engineer chose to use design
guidelines commonly accepted in North Carolina by the U.S. Soil Conservation Service.Most of
this design criteria was obtained from published articles of researchers and extension specialists at
North Carolina State University.
Design Treatment Volume:
Design Treatment Volume = 1 cu.ft./lb.animal wt.
1 cu.ftdlb.x 30lbsJanimal x 3,840 animals= 115,200 cu.ft.
or
115,200 cu.ft.x 7.48 galJcu.ft.= 861,696 gallons
Practical design range=800,000 to 900,000 gallons
i The water level (minimum design volume)in this lagoon will vary depending on wastewater
1 productions and irrigation schedule.Water depths of at least 6 feet should be maintained under
normal conditions.
4. F. Six Month Wastewater And Rainfall Storage
Wastewater will most often be pulled off of the top of the primary treatment lagoon and recycled to
the confinement buildings for re-use. Water accumulation above the Design Treatment Volume will
eventually be spray irrigated to crops. Naturally the farmer will not desire to irrigate every day or
every week. Likewise there will be time periods when the weather will not permit responsible
irrigation. This requires there to be storage volume built into the lagoon(s)to give the farmer safety
and flexibility in the irrigation routine. The time period for this part of the design can vary between
three and six months.
To provide that extra margin of safety six months storage will be used in the Johnson Farm lagoon
design. The six month storage volume includes excess wastes produced by the animals,spillage
or wasted water,clean-up water,and excess rainfall(less evaporation)directly into the lagoon.
This does not include rainfall run-off water from outside the lagoon since that will be diverted by
earthen embankments and grass water ways.
Six Month Storage Needed:
0.5 cu.ft.11b.x 30lbs.lanimal x 3,840 animals= 57,600 cu.ft.
or
57,600 cu.ft.x 7.48 gal.lcu.ft.= 430,848 gallons
The farmer may wish to install a pole inside the lagoon so the operator can tell at a glance the
current water level and volume inside the lagoon. This measuring device should be well marked
and be of a design which best serves the operator's purpose. Once the lagoon reaches steady
state,a familiar water mark around the sides of the lagoon will serve the same purpose.Proposed
lagoon dimensions and volumes are shown in Exhibit 5.

Phase 1 January 10, 1995
4. G. Severe Storm Storage
+ At any time in North Carolina there can occur a severe rain producing storm which can deposit
I considerable amounts of water quickly. This fad should be considered when designing a lagoon
and allowances made to accommodate this extra water.
The standard storm surge allowed in lagoon design is the 25 year-24 hour rainfall event. This
storm event is historically different between the Mountains, Piedmont,and Coastal plain and can
u even vary between neighboring cities.
I Climatic data from the U.S.Weather Bureau was available to give the designer reasonably
accurate information about such rainfall events. The 25 year-24 hour storm for the Greensboro
area is 5.84 inches.For conservative reasons the engineer chose to use 6.41 inches as a design
number for Montgomery County.
The design engineer is only considering the rainfall falling within the interior of the lagoon. There
Should Be No Surface Run-Off From Surrounding Areas Allowed To Enter The Lagoon.All
Run-Off Shall Be Diverted Around The Lagoon Via Earthen Embankments,Grass Water
i Ways, Or Similar Water Diversion Techniques.
I The 25 year-24 hour storm volume for the Johnson Farm is calculated to be approximately:
I Primary Lagoon Severe Storm Volume
Total lagoon acreage=Assumed at 0.63 acres.
6.41 inches x 0.63 acres=4.04 ac-in or.34 ac-ft
0.34 ac-ft x 43,560 cu.ft./ac-ft= 14,810 cu.ft.
or
14,810 cu.ft.x 7.48 gal/cu.ft.= 110,779 gallons
4. H. Freeboard
Freeboard is the extra depth added to a lagoon for safety against an embankment overflow or dam
washout. This extra depth is a safety measure and prevents water from spilling over the dam,
resulting in dam erosion and complete or partial failure. This amount of added depth is usually
i selected to be 1 foot but can be 2 feet in some cases. Freeboard was selected to be 1 foot at the
Johnson Farm.
Primary Lagoon Freeboard: 1 foot.
4. I. Emergency Spillway Or Overflows
If the lagoon effluent maximum level is located 3 feet or more above the natural grade outside of
the lagoon,the lagoon shall be provided with an emergency overflow spillway.
The discharge or overflow of swine effluent to the surface waters of N.C.is prohibited.
However,in the unlikely event the water level inside a lagoon should exceed the maximum high
water level it should have a predetermined path of overflow in order to safeguard the dam. This
emergency spillway should be located on undisturbed,firm soil not easily eroded or on a very solid
surface like bedrock,away from the lagoon dam if possible,or in a position where minimal dam
height is found.Either overflow pipes or earthen overflows may also be used.
Page 9

Phase 1 January 10, 1995
The amount of water to be safely passed by an emergency overflow will depend on several factors
and the degree of safety the designer requires.The emergency spillway should pass the overflow
f water without over-topping the embankments or dam.
According to SCS guidelines(fable 4-Minimum Spillway Design Storm)the Johnson Farm
lagoon spillway should be designed for a 10 year-24 hour storm. The engineer feels that a
shorter duration more intense storm would be a more conservative design,therefore the engineer
decided to use a 25 year- 1 hour storm for emergency spillway design.Weather data for
Greensboro, N.C. suggests rainfall during this storm event at:
25 year- 1 hour storm= 2.74 inches
Emergency Spillway Or Overflows
Average flow calculates to be:
2.74 in./hr.x 0.63 acres x 3,631 cu.ft.lac:in.=6,268 cu.ft./hr.
6,268 cu.ftJhour 13,600 seconds/hour= 1.74 cu.ft./sec. (cfs)
The contractor may use a flat overflow cut into a side of the lagoon or a pipe to convey the
overflow. Earthen overflows shall have sufficient vegetation maintained to prevent scouring of the
soil.Where earthen overflows are used the spillway shall have an outlet a minimum of 4 feet wide
and level across the width no matter how small the lagoon structure is designed. Normally a wider
i earthen overflow will be required. The engineer used table 8.07d from the"Erosion And Sediment
I Control Planning And Design Manual", published by the North Carolina Department of
i Environment, Health,and Natural Resources,Land Quality Section to determine emergency
overflow dimensions. Recommendations on width will appear in Exhibit 5.
If the emergency overflow is earthen, a good grass cover shall be maintained along its length. The
spillway should be designed so that any overflows would be conveyed well passed the lagoon
construction area. A combination of grass,rock rip rap,etc.may be used for the control of erosion
in the event of an emergency overflow for earthen overflows. KEEP IN MIND,THE EMERGENCY
OVERFLOW SHOULD NEVER BE USED IF IT CAN BE AVOIDED.
Based on information obtained in the manual titled"Erosion And Sediment Control Planning And
Design Manual",published by the North Carolina Department of Environment, Health,and Natural
Resources,Land Quality Section,the engineer has decided to use an earthen overflow for the
lagoon. It is suggested the emergency overflow entrance for the lagoon overflow be 1 foot below
the lowest point of any earthen embankments around the lagoon perimeter. The emergency
overflow elevations should be verified with a transit after construction.
4. J. Lagoon Dam Considerations
The lagoon dam shall be earthen. The constructed top of the Primary Treatment lagoon dam is
designed to be roughly at the 84 foot contour. This dam shall be roughly 14 feet tall at its highest
point measured to the outside toe. The dam height shall be made to allow for 2 to 5 percent
settling. If a concerted effort is made to compact the soil within the dam,a 2 percent settling figure
may be used. The dam top width shall be at least 10 feet wide. Final dam dimensions and
elevations will depend on on-site parameters and constraints.
Page 10

Phase I January 10, 1995
A dam core or key shall be installed along the center line of the dam along its longitudinal axis.
This dam core shall extend up either side of the natural side slopes so as to form a barrier to water
seepage under the dam and to prevent long term dam movement. The dam core shall be
sufficiently wide to allow earth moving machinery tires or tracks to pack all areas of the fill by
driving over the fill.A sheep's-foot roller or vibrating roller is recommended for packing the dam
and any clay surfaces. It is expected the dam core will need to be a minimum of 10 feet wide, but
this will depend on the packing technique. The core shall be taken to a depth sufficient to reach a
solid,low permeability clay base, but no less than 2 feet deep.The core should not be taken to a
fractured rock base.
The core shall be backfilled with a relatively impermeable clay material of sufficient moisture
content to pack well via earth moving machinery. Sufficient clay material may not be available on
the Johnson Farm to provide this material. If good clay material is not available it shall be imported
to the site. Dam core backfill material shall be free of boulders,roots,sod,frozen soil, brush,and
other unsuitable material. The backfill material shall not contain rocks greater than 6 inches in
diameter. Core fill shall be installed in layers 8 inches thick or less. Repeated passes with a
sheep's-foot roller is recommended to compact the core and dam back fill material at each soil
layer, but other earth moving machinery may be used if repeated passes are made over the enfire
dam core (plus the above grade dam structure)with loaded pans for compaction. The dam core
shall be free of standing water when backfilling begins.
The natural base on which the dam is to sit is recommended to have a slope 4:1 or less steep
before construction starts. Natural grade can be used once grass and vegetation have been
removed and if the site is not severely rocky,soft,wet,or steep. The natural grade shall be
developed to remove all trees,shrubs, grasses,boulders,etc.and scarified before fill is added.
This type activity will help assure a good bond between the first layer of fill material and native
material. Moisture can be added to the native material if needed for a good bond.
An effort shall be made to use uniform materials though out the fill. Alternating layers of dissimilar
materials is discouraged. When dissimilar materials are used the most impermeable materials
should be used at dam center and on up stream portions of fill. Eliminate voids during fill
operations.
The back slope of the dam shall not be steeper than 2.5:1. A 3:1 slope or 4:1 slope is
recommended. The inside of the dam can have a slope of 2:1,2.5:1,or 3:1. A 3:1 inside slope is
recommended if the contractor can not make the slope any steeper. The front and back portions of
the dam should have a combined ratio of at least 5 horizontal to 1 vertical.. Exhibit 5 shows more
detail on the dam construction.Dam construction will be checked by the project engineer and SCS
personnel if the SCS is available.
The dam shall not be more than 15 feettall,measured from the top of the dam to the outside toe,
and will not require a permit from the North Carolina Department of Environment, Health, and
Natural Resources(NCDEHNR)under the Dam Safety Act,

3. E. Adjacent Property Near The Proposed Construction Site
As mentioned above, the farm under study has been used for agriculture and is in a rural setting.
Exhibits 2, and 3 show some property features. The following is a general description of the land
adjoining or near the proposed lagoon site.
All Sides—Wooded area except what has been cleared for future pasture land.
There are no dwellings, structures, roads, or bridges between the proposed lagoon site and the
nearest creek or branch. No towns or municipalities are known to get their water from nearby
streams which would be impacted immediately by a dam breach. The nearest stream or river is
the Naked Creek and it is approximately 800 feet away from the site in a direct vector. From a
structures and environmental standpoint,the engineer thinks this lagoon would be a classified low
hazard.
4. Lagoon Design Parameters And Details (Proposed)
4. A. General Farm Parameters
1. Type of facility: Nursery.
2. Number of hogs: 3,840 head.
3. Average animal weight assumed: 30 pounds.
4. Size of lagoon in gallons (Approximate) 1,576,000 million
5. Total number of acres at the farm(est.) 210+/- acres
6. Number of acres in lagoon and confinement 3 acres
houses (approximately).
4. B. Type Of Treatment
Certain forms of liquid waste treatment lagoons have been used for hundreds of years. With the
on-set of larger and more intensive farming operations over the last 30 years, the use of on-farm
lagoons has increased as part of the overall waste management scheme. Simply put, waste
treabnent lagoons are designed to both store and treat the wastes from many types of animal
' confinement operations (usually for wastes in a liquid or slurry form). These lagoons rely on
bacteria to decompose the organic matter in the wastewater into gases, liquids, and sludges or
solids. In addition significant pathogen reduction is achieved by the process. Two types of
lagoons that are sometimes used in wastewater treatment are aerobic and anaerobic lagoons.
Both aerobic and anaerobic type lagoons are effective in treating animal wastes, however the most
common type of lagoon in use for the treabnent of swine effluent is the anaerobic type lagoon. An
anaerobic lagoon system is being designed for the Naked Creek II Farm. Further discussions
within this report will be confined to the anaerobic lagoon design process.
Anaerobic lagoons develop bacteria populations which thrive without the presence of oxygen.
These lagoons usually contain considerably more volume than aerobic lagoons and are normally
deeper. Anaerobic lagoons are well suited for high strength wastewaters such as swine manure.
6

The anaerobic process decomposes more organic matter per unit volume than does the aerobic
process and is a good method of pathogen reduction. Since anaerobic lagoons are not
mechanically aerated they do not consume electrical power and are generally low maintenance,as
compared to the aerobic lagoon. If properly constructed and maintained anaerobic lagoons offer
good effluent treatment and adequate odor controls.
Sudden changes in nutrient loadings or changes in temperature can cause a disruption in the
anaerobic microbial process, often resulting in periods of odorous gases being released. Upsets
due to changes in weather for instance are normally short lived provided there has not been a
severe bacteria population reduction. Anaerobic lagoons in warmer climates do not tend to suffer
the severe seasonal problems that colder climates report.
Lagoon design documents and research reports often give numbers related to the design process.
These numbers vary depending on which publication is reviewed. One fad remains constant
throughout literature;Farm Management Has As Much To Do With Odor Minimization As Does
Proper Lagoon Deslgn1 However since teaching proper farm management (including proper
waste management) is beyond the scope of this document, discussion on physical lagoon design
criteria will be the emphasis presented below. The engineer has used design data accepted and
used by the N.C.Cooperative Extension Service at NCSU for basic design parameters. Reasoning
for variations in design will be clearly stated.
4. C. Lagoon Shape
There is no one special shape required for the design of anaerobic lagoons. However due to
construction ease most lagoons (especially in the coastal plain of North Carolina) are rectangular
in overall shape with a trapezoidal cross section. Lagoons in the Piedmont are often less uniform
in shape due to depth-to-rock. Flat or nearly flat bottoms are also desirable but not a requirement.
One will find many shapes of anaerobic lagoons functioning well. Lagoon volume is a more
important criteria than is shape. Very Shallow water depths are discouraged.
For brevity,all of the details associated with estimating lagoon volumes will not be presented in this
document. However important design values are presented below.
The lagoon at this site is being designed with a rectangular surface and flat bottom. A synthetic
liner is being recommended and has been approved by the owner. It will have a trapezoidal cross
section with an interior slope of 2:1.Outside side slopes shall be 3:1 or greater.
Most clay soils will allow side slopes in lagoon construction to be made 1:1, 2:1, 3:1 or less steep
however there is some soil stability disadvantage to side slopes of 1:1, thus seldom is a 1:1 side
slope used. The interior sides of this lagoon was chosen to be made 2:1 because of using a
synthetic liner. However a 3:1 slope can be used if earth moving equipment can not go steeper.
Outside slopes of earthen berms or dams should not exceed 3:1 so regular maintenance and
mooring can be conducted. Outside slopes of 4:1 or greater are acceptable providing the height of
the dam in reference to the outside toe is less than 15 feet. Dams above 15 feet require special
permitting and must meet additional dam safety criteria.

4• D. Sludge Holding Capacity
A common practice of the modern swine producer is to irrigate sludge when land application
events occur.This is usually done by first agitating the lagoon effluent to mix up the solids and the
liquids. This practice helps prevent sludge accumulation on the lagoon floor. Sludge irrigation is a
management decision and does tend to increase the amount of objectionable odors if done at the
wrong times or seasons.Any sludge agitafion will produce some offensive odors while the effluent
is being mixed.
Mr. Johnson wishes to agitate his lagoon on occasion and irrigate the solids along with the liquid.
However for safety purposes the engineer has designed a 5 year sludge accumulation into this
lagoon.The amount of sludge accumulation over a 5 year period is estimated to be about 194,743
gallons (26035 cubic feet). This value was derived using an equation developed at NCSU by Dr.
L.M. Salley, based on field measurements of existing lagoons. If irrigation of solids does occur
more often than every 5 years,the farmer can expect less sludge accumulation.
4. E. Design Treatment Volume
The design treatment volume (sometimes called Minimum Design Volume) is the volume of
wastewater needed to maintain optimum conditions for bacterial growth. This volume may require
several months to obtain once filling begins. The owner should be careful to add water to the
lagoon until one third to one half of the design treatment volume is achieved before adding swine
manure.
The operator should always strive to maintain a liquid depth greater than 6 feet to control
excessive odors. Initial water addition to the lagoon shall be from on-site water wells, creek water
pumped into the lagoon or from intentionally diverted rainfall run-off.
There are some differences of opinion on the amount of volume necessary to achieve adequate
odor control in anaerobic lagoons. Conventional practice says bigger is better, and there are
several reported benefits to designing a large treatment volume. for instance, the extra water
offers dilution to the swine manure at first, giving the operator a little more treatment buffer in the
early year(s) of the lagoon's life. Concentrations of nutrients will eventually increase to a steady
state in both extra large lagoons and smaller lagoons.
Researchers at NCSU have conducted field work on hundreds of lagoons and seen many types of
operations. The general consensus is that lagoon management makes more difference than size
in minimizing lagoon odors, provided that the lagoon is not grossly undersized. Even lagoons of
very large size can produce abnormal amounts of odor 'd improperly managed. The Natural
Resources Conservation Service (NRCS) in North Carolina uses research data developed at
NCSU for designing anerobic swine effluent lagoons. Through out this document the engineer
chose to use design guidelines commonly accepted in North Carolina by the NRCS. Most of this
design criteria was obtained from published articles of researchers and extension specialists at
North Carolina State University.
s

Primary Treatment Lagoon:
Design Treatment Volume = 1 cu.Ulb.animal wt
1 cu.ft./lb.x 30lbs.lanimal x 3,840 animals= 115,200 cu.ft.
or
115,200 cu.ft.x 7.48 gal./cu.ft= 861,696 gallons
Practical design range-800,000 to go0,000
The water level (minimum design volume) in this lagoon will vary depending on wastewater
productions and irrigation schedule. Water depths of 6 feet should be maintained under normal
conditions.
■ 4. F. Six Month Wastewater And Rainfall Storage
I� Wastewater will most often be pulled off of the top of the lagoon and recycled to the confinement
buildings for re-use. Water accumulation above the Design Treatment Volume will eventually be
spray irrigated to crops. Naturally the farmer will not desire to irrigate every day or every week.
Likewise there will be time periods when the weather will not permit responsible irrigation. This
requires there to be storage volume built into the lagoon to give the farmer safety and flexibility in
the irrigation routine. The time period for this part of the design can vary between three and six
months. Likewise wastewater storage helps with the management of crops grown for wastewater
irrigation.
To provide that extra margin of safety,six months storage will be used in the Naked Creek II Farm
lagoon design. The six month storage volume includes excess wastes produced by the animals,
spillage or wasted water, clean-up water, and excess rainfall (less evaporation) directly into the
lagoon. This does not include rainfall run-off water from outside the lagoon since that will be
diverted by earthen embankments and grass water ways.
Six Month Storage Needed:
0.5 cu.ftlib.x 30lbs./animal x 3,840 animals= 57,600 cuft
f or
57,600 cu.ft x 7.48 gal./cu.ft.= 430,848 gallons
The farmer shall install a pole or other gauged measuring device inside the lagoon so the operator
can tell at a glance the current water level and volume inside the lagoon. This measuring device
should be well marked and be of a design which best serves the operator's purpose. Once the
lagoon reaches steady state a familiar water mark or flag will serve the same purpose.
Proposed lagoon dimensions and depths are shown on Exhibit 5.
4. G. Severe Storm Storage
At any time in North Carolina there can occur a severe rain producing storm which can deposit
considerable amounts of water quickly. This fact should be considered when designing a lagoon
and allowances made to accommodate this extra water.
The standard storm surge allowed in lagoon design is the 25 year- 24 hour rainfall event. This
storm event is historically different between the Mountains, Piedmont, and Coastal plain and can
even vary between neighboring cities.
f' 9
E

Climatic data from the U.S. Weather Bureau was available to give the designer reasonably
accurate information about such rainfall events. The 25 year-24 hour storm for the Montgomery
County area is around 6.41 inches.
The design engineer is only considering the rainfall falling within the interior of the lagoon. There
Should Be No Surface Run-Off From Surrounding Areas Allowed To Enter The Lagoon. All
Run-Off Shall Be Diverted Around The Lagoon Via Earthen Embankments, Grass Water
Ways,Or Similar Water Diversion Techniques.
The 25 year-24 hour storm volume for the Naked Creek If Farm is calculated to be approximately:
Primary Lagoon Severe Storm Volume
Total lagoon acreage=Assumed at 0.53 acres.
6.41 inches x 0.53 acres=3.4 ac-in or 0.28 ac-ft
0.28 ac-ft x 43,560 cu.ftJac-ft= 12,197 cu.ft.
or
12,197 cu.ft.x 7.48 gallcu.ft.=91,234 gallons
4. H. Freeboard
Freeboard is the extra depth added to a lagoon for safety against an embankment overflow or dam
washout. This extra depth is a safety measure and prevents water from spilling over the dam,
resulfing in dam erosion and complete or partial failure. This amount of added depth is usually
selected to be 1 foot but can be 2 feet in some cases. Freeboard was selected to be 1 foot at the
new Johnson Farm.
Primary Lagoon Freeboard: 1 foot.
4. 1. Emergency Spillway Or Overflows
If the lagoon effluent maximum level is located 3 feet or more above the natural grade outside of
the lagoon,the lagoon shall be provided with an emergency overflow spillway.
The discharge or overflow of swine effluent to the surface waters of N.C. is prohibited.
1 However, in the unlikely event the water level inside a lagoon should exceed the maximum high
water level it should have a predetermined path of overflow in order to safeguard the dam. This
emergency spillway should be located on undisturbed,firm soil not easily eroded or on a very solid
surface like bedrock, away from the lagoon dam if possible, or in a position where minimal dam
height is found.Either overflow pipes or earthen overflows may also be used.
Because a synthetic liner is being used at this farm and because there is not a true dam to
t potentially fail, the engineer does not see the critical need for an emergency overflow and is not
specifying such.
4. J. Lagoon Dam Considerations(i.e.stormwater diversion)
The dam at the Naked Creek II farm lagoon is not actually a dam but is more like a stormwater
' diversion embankment. However embankment construction quality should not be minimized. High
water conditions in the lagoon could push outwardly on the embankment and cause some minor

movement. Below the reader will see some construction details for dams and earthen
embankments.
The lagoon dam shall be earthen. The constructed top of the lagoon dam is designed to be
roughly at the 86 foot contour based on the 100 feet reference set by the engineer. The 100 feet
contour has been marked by a nail and ribbons on a tree southeast of the proposed lagoon site.
The dam shall be roughly 3 feet tall at its highest point measured to the outside toe. The dam
height shall be made to allow for 2 to 5 percent settling. If a concerted effort is made to compact
the soil within the dam, a 2 percent settling figure may be used.
The dam top width shall be at least 10 feet wide.A short embankment(such as on this lagoon)
shall have a top width of at least 5 feet wide.
A shallow dam core or key shall be installed along the center line of the embankment along its
longitudinal axis. This dam core shall extend around the lagoon rim.The dam core shall be 3 feet
wide at the top to allow a single earth moving machinery tire or track to pack all areas of the fill by
driving over the fill. A sheeps-foot roller or vibrating roller is recommended when building
embankment height.
The embankment core shall be taken to a depth of 2 feet.
The care shall be backfilled with a relatively impermeable clay material of sufficient moisture
content to pack well via earth moving machinery. Sufficient sand/clay material should be available
on the Johnson Farm to provide this material. Dam core backfill material shall be free of boulders,
roots,sod,frozen soil, brush, and other unsuitable material. The backfill material shall not contain
rocks greater than 6 inches in diameter. Core fill shall be installed in layers 8 inches thick or less.
Repeated passes with a sheeps-foot roller is recommended to compact the core and dam back fill
material, but other earth moving machinery may be used if repeated passes are made over the
dam core with loaded pans for compaction. The dam core shall be free of standing water when
backfilling begins.
The natural base on which the dam sits is recommended to have a slope 4:1 or less steep before
construction starts. Natural grade can be used once grass and vegetation have been removed and
if the site is not severely rocky, soft, wet, or steep. The natural grade shall be developed to
remove all trees,shrubs,grasses,boulders,etc.and scarified before fill is added.This type activity
will help assure a good bond between the first layer of fill material and native material. Moisture
can be added to the native material V needed for a good bond.
An effort shall be made to use uniform materials though out the fill. Alternating layers of dissimilar
materials is discouraged. When dissimilar materials are used the most impermeable materials
should be used at dam center and on the inner face of the dam. Eliminate voids during fill
operations.
The back slope of the dam shall not be steeper than 2.5:1. A 3:1 slope or 4:1 slope is
recommended. The inside of the dam can have a slope of 2:1, 2.5:1,or 3:1. A 3:1 inside slope is
recommended. The front and back portions of the dam should have a combined ratio of at least 5
horizontal to 1 vertical. Exhibit 5 shows more detail on the dam construction. Dam construction will
be checked by the project engineer as needed.

The dam shall not be more than 15 feet tall, measured from the top of the dam to the outside toe,
and will not require a permit from the North Carolina Department of Environment, Health, and
Natural Resources(NCDEHNR) under the Dam Safety Act.
