The Waste Utilization table shown below summarizes the waste utilization plan for this operation. This plan provides an estimate of the number of acres of cropland needed to use
the nutrients being produced. The plan requires consideration of the realistic yields of the crops to be grown,their nutrient requirements, and proper timing of applications to
maximize nutrient uptake.This table provides an estimate of the amount of nitrogen required by the crop being grown and an estimate of the nitrogen amount being supplied by manure or other by-products,
commercial fertilizer and residual from previous crops. An estimate of the quantity of solid and liquid waste that will be applied on each field in order to supply the indicated quantity
of nitrogen from each source is also included. A balance of the total manure produced and the total manure applied is included in the table to ensure that the plan adequately provides
for the utilization of the manure generated by the operation.

The following Lagoon Sludge Nitrogen Utilization table provides an estimate of the number of acres needed for sludge
utilization for the indicated accumulation period. These estimates are based on average nitrogen concentrations for each source,
the number of animals in the facility and the plant available nitrogen application rates shown in the second column.
Lagoon sludge contains nutrients and organic matter remaining after treatment and application of the effluent. At clean out, this
material must be utilized for crop production and applied at agronomic rates. In most cases, the priority nutrient is nitrogen but
other nutrients including phosphorous,copper and zinc can also be limiting. Since nutrient levels are generally very high,
application of sludge must be carefully applied.
Sites must first be evaluated for their suitability for sludge application. Ideally, effluent spray fields should not be used for
sludge application. If this is not possible, care should be taken not to load effluent application fields with high amounts of
copper and zinc so that additional effluent cannot be applied. On sites vulnerable to surface water moving to streams and lakes,
phosphorous is a concern. Soils containing very high phosphorous levels may also be a concern.

The Available Waste Storage Capacity table provides an estimate of the number of days of storage capacity available
at the end of each month of the plan. Available storage capacity is calculated as the design storage capacity in days
minus the number of days of net storage volume accumulated. The start date is a value entered by the user and is
defined as the date prior to applying nutrients to the first crop in the plan at which storage volume in the lagoon or
holding pond is equal to zero.
Available storage capacity should be greater than or equal to zero and less than or equal to the design storage
capacity of the facility. If the available storage capacity is greater than the design storage capacity,this indicates that
the plan calls for the application of nutrients that have not yet accumulated. If available storage capacity is negative,
the estimated volume of accumulated waste exceeds the design storage volume of the structure. Either of these
situations indicates that the planned application interval in the waste utilization plan is inconsistent with the
structure's temporary storage capacity.

Required Specifications For Animal Waste Management
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 that 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 Management Plan when there is a change in the
operation, increase in the number of animals, method of application, receiving
crop type, or available land.
i
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 aefe 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 by 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.
------ ------ --- - -- ---- - -- ----------------- ---- ---- - --- ---------------------- ------ ----------------- - ---- - ---
715478 Database Version 3.1 Date Printed: 11/14/2005 Specification Page 1

8. Animal waste shall not be applied to saturated soils, during rainfall events, or
when the soil 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.
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 that 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 a discharge or by over-spraying. Animal waste maybe 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.

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 direst 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 soils 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 five (5)
years.
23. Dead animals will be disposed of in a manner that meets North Carolina
regulations.

Crop Notes
The following crop note applies to field(s): 35
Bermudagrass Coastal Plain, Mineral Soil, Moderately Well Drained.
Adaptation: Well-adapted.
In the Coastal Plain,hybrid bermudagrass sprigs can be planted Mar. 1 to Mar. 31. Cover sprigs 1" to 3"
deep (1.5" optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and
wind. For Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a
rate of 30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing
conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced 1' to 1.5' in row.
For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime,phosphorus,
potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 100 lb/ac N in
the establishment year in split applications in April and July. For established stands apply 180 to 240
lb/ac N annually in split applications, usually in April and following the first and second hay cuts.
Reduce N rates by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization
of Pastures and Forages in North Carolina for more information or consult your regional agronomist or
extension agent for assistance.
The following crop note applies to field(s): 35
Small Grain: CP, Mineral Soil, medium leachable
In the Coastal Plain, oats and barley should be planted from October 15-October 30; and rye from
October 15-November 20. For barley, plant 22 seed/drill row foot and increase the seeding rate by 5% for
each week seeding is delayed beyond the optimum time. See the seeding rates table for applicable
seeding rate modifications in the current NCSU "Small Grain Production Guide". Also, increase the
initial seeding rate by at least 10% when planting no-till. Oats should be planted at 2 bushels/acre and
rye at 1-1 1/2 bushels/acre. Plant all these small grains at 1-1 1/2" deep. Adequate depth control is
essential. Review the NCSU Official Variety "green book" and information from private companies to
select a high yielding variety with the characteristics needed for your area and conditions. Apply no more
than 30 lbs/acre N at planting. Phosphorus and potash recommended by a soil test can also be applied at
this time.The remaining N should be applied during the months of February-March.

IRRIGATION SYSTEM DESIGN
The Craig Perry swine farm is located on SR 1003 in Halifax County near Scotland Neck, NC. An irrigation
system for land application of swine waste is required for the for the facility to be certified under 15A NCAC
.0200 Division of Water Quality regulations. This document presents detailed calculations and specifications
for the proper irrigation system to be installed given soil and crop parameters, geometry of the fields to be
utilized, and financial constraints.
A solid set (permanent) irrigation system is recommended for this farm. All sprinklers will be single nozzle
full circle preferably Senninger Model 7025RD-1-1"M #18(9/32”) @ 55 psi and sprinkler height of 1.5' off
the ground. The sprinkler radius is approximately 70 ft. with each sprinkler spaced at 84 ft. x 84 ft. Spacing
is 60% of diameter which provides a good coefficient of uniformity.
Four fields have been made available for irrigation. The animals will produce a total of 9,200 lbs of Plant
Available Nitrogen (PAN) per year (2.3 lbs of PAN/head/year x 300 head = 690 lbs of PAN/year). Coastal
Bermuda is planned to be sown into Exum soil and Fescue in Gritney and Exum. The Realistic Yield
Expectations (R.Y.E.) for coastal Bermuda on Exum is 6.5 tons/ac, the RYE for Fescue on Exum is 4.3
tons/ac., and the RYE for Fescue on Gritney is 3.8 tons/ac. See the attached calculations for how much
nitrogen each field can uptake per acre.
Approximately 32.89 acres is required for proper waste application. Therefore, 203 full circle sprinklers
spaced at 84 feet by 84 feet with a radius of 70 feet will provide an effective irrigated area of approximately
33 acres. Per the attached construction plan there appears to be sufficient land available for proper waste
application at this site.
The four fields proposed for irrigation are under one ownership. Therefore, the irrigation system has been
laid out without respect to field boundaries in fields 35 and 35a and also in fields 32 and 34. No property
buffers are used. Per John Clark of the NRCS-Halifax County field office, Mr. Perry will obtain a notarized
agreement with her property owner on the South side of his property which allows him to spray up to the
property line and wave the 50' buffer.

Please note that the current waste utilization plan has field 32a sown in Fescue. This design
will be invalid if all of fields 35 and 35a are not sown in coastal Bermuda. Fields 32 and 34
may remain in Fescue.
The maximum friction loss in the supply and lateral lines should not exceed 10 psi. A 4-inch lateral
servicing between 12 and 15 sprinklers, a 3-inch lateral servicing between 5 and 11 sprinklers, and a
2-inch lateral servicing between 1 and 4 sprinklers will produce a maximum friction loss (in the
longest lateral less than 7.90 psi. A 6-inch supply line will produce friction loss of 2.68 psi. Inlet
pressure to the first sprinkler on each lateral should be maintained at 59 psi. All lines (supply and
laterals)will be connected using bell and gasket joints. A 4-inch brass or plastic gate or globe valve
will control the flow to each lateral. (see construction plan).
The pump and electric motor should be a 20 HP three phase with a capacity of 256.5 gpm at 177.0
feet of Total Dynamic Head (TDH) with a pump efficiency of at least 70.25% and a Net Positive
Suction Head Required (NPSHR) less than 12 feet. A Berkley Model B2 1/2 ZPL with a 7 11/16-
inch impeller diameter is recommended. Impeller may be trimmed slightly based on manufacturer's
recommendations. This is available (and is recommended) in a cast iron pump, closed coupled with
a nominal 3600 rpm motor. Safety controls include a manual disconnect switch, magnetic starter
with properly sized heaters (no more than 1.5 amp above rated operating current).
On the discharge side of the pump, both a gate valve and a check valve need to be installed. The
check valve will prevent flow back through the pump when the system is shut down. The gate
valve will be used to control the pump discharge. Also on the discharge side of the pump an air
relief/vacuum relief valve, and a pressure relief valve should be installed. See construction plan for
placement of additional 2 or 3 inch air relief/vacuum release valves. These valves can be aluminum
or cast iron, but they should be rated at a minimum of 150 psi working pressure. These valves will
be supported by a metal angle iron or wooden post. Some kind of priming device will need to be
installed on the suction side of the pump. The suction pipe should be at least 6-inch in diameter.
Some kind of strainer needs to be installed on the end of the suction pipe. A foot valve can be an
optional item. While it works, it reduces the priming requirements.
There should be thrust blocks placed at all bend, tee, and valve locations. From NRCS 430 DD,
thrust blocks for dead ends and tees are 0.7 that for 90 degree elbows. There is not a calculation
for a ground entry or Z pipe. It probably should be 25 to 33 percent more than that required for a
90 degree elbow. See calculations for thrust block sizing.
All risers shall be equipped with a Webstermatic V quick coupler. The exact type of riser
connections to the laterals shall be determined by the installer based on the best interest of the
farmer(ie. connection which will allow the farmer the best access for maintenance and repair of the
riser connections). Quick couple will need to be protected by use of a rubber cover. Recommend
using two or three elbow connection for lateral protection. All fitting, connections, valves, tees,
etc. shall be class 200 or Sch. 80.

System Operation
This system is a 14-zone system. Each zone has 14 to 15 sprinklers. One zone is operated at a time
by opening a valve and then starting the pump. The maximum run time for each zone should be
approximately 128.55 minutes. Approximately 4.78 inches of irrigation at 0.5-inch applications
with an average of 20.5 hours of irrigation per zone per year for zones 1-9 is ideal. For zones 10-12
3.16 inches of irrigation at 0.5 inch applications with an average of 13.6 hours of irrigation per
zone per year is ideal. And finally for zones 14 and 15, 2.79 inches of irrigation at 0.5-inch
applications with an average of 12.0 hours of irrigation per zone per year is preferred. For all 14
zones the system will require approximately 248.9 hours of pumping per year. The precipitation
rate for this design is
96.3 x 17.1 gpm/(84' x 84') = 0.233 in/hr
While an hour meter or flow meter is not required on the pump, it is important that good records be
kept of the number of hours of operation. Rainfall events may increase or decrease the total amount
of wastewater that has to be pumped. On the average a total of approximately 249 hours of
pumping will be required each year.
During the winter months when temperatures are below freezing the risers need to be drained at
least into the lateral lines. Water should not freeze at the buried depth of 24 inches which is the
recommended depth for laterals and supply lines. The pump, suction pipe and ground entry pipe
need to be drained or protected from freezing using heat tape or some other type of heat. Sprinklers
and air relief/vacuum release valves should be checked periodically to ensure that they are operating
properly. Check to ensure that the pressure gauge at the pump is operating properly. The pressure
gauge should be glycerin filled to ensure that the wastewater does not damage it.
It is not necessary that the pump, motor and control panel be placed in a shelter, but it is
recommended that a small building be constructed to house the equipment.
Record Keeping & System Operation Evaluation
Accurate records should be maintained on all land application of wastewater. The two forms IRR-
1 and IRR-2 which are contained in the Certification Training for Operators of Animal Waste
Management Systems Manual which operators received when they attended the operator
certification training are excellent for this use. This allows the operator to record when the system
was operated, the length of time and the amount of effluent applied. These records need to be
maintained for five years. This includes pumping records and also lagoon level records. Senate Bill
1217 also requires that the soil be sampled annually within 60 days of land application. It is
suggested that the lagoon be sampled quarterly.
The irrigation system should be operated in daylight hours, and in conditions where wind speeds
are less than 10 mph. Each time the system is operated, the operator should check for leaks,

Halifax County September 19 1997
malfunctioning sprinklers or pump or any other things that might affect system uniformity. The
system should not be operated during freezing weather. With this system there should be a
minimum of maintenance. The electric motor and pump require little maintenance except for
draining the pump during freezing weather and checking the sprinkler for nozzle wear or proper
rotation. If the pump has a packing seal it may need to be adjusted so that leakage is not excessive.
The leakage should be piped back to the lagoon.
There should be a pressure gauge at the pump and one located on the sprinklers in the field. This
will allow the operator to ensure that there is adequate pressure on the sprinklers in the field.
There is also a requirement that and Emergency Action Plan (EAP) be prepared for the farm.
Details of the EAP are given in Chapter 5, of the Certification Training for Operators of animal
Waste Management Systems Manual. This plan deals with lagoon overflow, runoff from waste
application fields, leakage from the waste distribution system and leakage from the base or side
walls of the lagoon. All of the items in the EAP are common sense things to do if there is a
problem. All farm workers need to be familiar with the plan and how to respond if an emergency
occurs.
Each farm will receive two inspections per year, one compliance inspection from the Division of
Water Quality (DWQ), and one operational inspection from the NC Division of Soil and Water
Conservation (DSWC). Both inspections will use the same forms. Items that are not in compliance
with the Waste Management Plan can be cited as violations. It is important that the Waste
Management Plan be implemented and followed.
The system should be evaluated annually using the procedures developed by specialist at North
Carolina State University. The evaluation brochures are available through the local North Carolina
Cooperative Extension Service Office.
If there are any questions or comments regarding the design of this irrigation system please contact
Brian Gannon, Division of Soil & Water Conservation-Wilmington Regional Office (910) 395-
3900.

SIZING THE PUMP
Craig Perry- DWQ ID No. 42-7
Route 1 Box 431 Scotland Neck, North Carolina 27874

[phone]
Apply energy equation between points 1) lagoon water surface and 2) sprinkler head.
Step -1 Determine Total Dynamic Head ITDHI
P1/water density+ V1**2/2g + Z1 + TDH = 132/water density+ V2**2/2g + Z2 + Hf
Assume friction head in the suction pipe and velocity head throughout the system to be negligible.
P1 = 0 (water pulled from a free surface.)
this Yeilds:
TDH = P2/water density+ Z2+ Hf-Z1
Z1(ft.) = 100 At lagoon stop pumping elevation
g (ft/sec**2) 32.4
Z2 (ft) = 109.5 At Sprinkler(1.5' above max ground elevation)
P2 (psi) = 55
Hf(ft.) = 24.41
TDH (ft.) = 160.83 (actual)
Add 10% to account for wear and tear on the pump and minor losses
in the valves and fittings
TDH (ft.) = 176.91 (design)
Step -2 Size Pump using a Performance curve
Pump Model Selection: B2 1/2 ZPL.
RPM 3600
hp= 20
eff.(%) = 70.25
Std. Impeller Dia (in.) = 7 11/16
Step -3 Determine Horse Power Requirements (hp)
hp= (Q*TDH)/(3960*eff.)
hp= 16.31 ok
Step -4 Size Impeller
Impeller Diameter should be trimmed slightly based on manufacturers recommendations
Step -5 Check NPSHA
NPSHR (ft.) per manufacturer's Sp. = 12
NPSHA (ft.) = Ha + Hs+ Hf+ Hvp
Assume Hf and Hvp to be neg.while He = 14.7psi or 34 feet
Hs (ft) = 7
NPSHA (ft.) = 27 ok

Information presented in manufacturers' charts are based on average
operating conditions for relatively new equipment. Discharge rates and appli-
cation rates change over time as equipment ages and components wear.As a
result, equipment should be field calibrated regularly to ensure that applica-
tion rates and uniformity are consistent with values used during the system
design and given in manufacturers'specifications. Field calibration is a simple
procedure involving collection and measurement of the material being
applied at several locations in the application area. This publication con-

An application uniformity greater than 75 is excellent for stationary spnnklers.
Application uniformity ibetween 50 to 75 is in the good range and is acceptable for wastewater

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.

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
2

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

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.
4

• Practice water conservation --- minimize building water usage and spillage from
leaking waterers, broken pipes and washdown through proper maintenance and water
conservation.
• Minimize feed wastage and spillage by keeping feeders adjusted. This will reduce the
amount of solids entering the lagoon.
Management:
• Maintain lagoon liquid level between the permanent storage level and the full
temporary storage level.
• Place visible markers or stakes on the lagoon bank to show the minimum liquid level
and the maximum liquid level. (Figure 2-1).
• Start irrigating at the earliest possible date in the spring based on nutrient
requirements and soil moisture so that temporary storage will be maximized for the
summer thunderstorm season. Similarly, irrigate in the late summer / early fall to
provide maximum lagoon storage for the winter.
• The lagoon liquid level should never be closer than 1 foot to the lowest point of the
dam or embankment.
• Don not pump the lagoon liquid level lower than the permanent storage level unless
you are removing sludge.
• Locate float pump intakes approximately 18 inches underneath the liquid surface and
as far away from the drainpipe inlets as possible.
• Prevent additions of bedding materials, long-stemmed forage or vegetation, molded
feed, plastic syringes, or other foreign materials into the lagoon.
• Frequently remove solids from catch basins at end of confinement houses or
wherever they are installed.
• Maintain strict vegetation, rodent, and varmint control near lagoon edges.
• Do not allow trees or large bushes to grow on lagoon dam or embankment.
• Remove sludge from the lagoon either when the sludge storage capacity is full or
before it fills 50 percent of the permanent storage volume.
• If animal production is to be terminated, the owner is responsible for obtaining and
implementing a closure plan to eliminate the possibility of a pollutant discharge.
Sludge Removal:
Rate of lagoon sludge buildup can be reduced by:
5

• proper lagoon sizing,
• mechanical solids separation of flushed waste,
• gravity settling of flushed waste solids in an appropriately designed basin, or
• minimizing feed wastage and spillage.
Lagoon sludge that is removed annually rather than stored long term will:
• have more nutrients,
• have more odor, and
• require more land to properly use the nutrients.
Removal techniques:
• Hire a custom applicator.
• Mix the sludge and lagoon liquid with a chopper- agitator impeller pump through large-
bore sprinkler irrigation system onto nearby cropland; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland; mix
remaining sludge; pump into liquid sludge applicator; haul and spread onto cropland or
forageland; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland;
dredge sludge from lagoon with dragline or sludge barge; berm an area beside lagoon
to receive the sludge so that liquids can drain back into lagoon; allow sludge to
dewater; haul and spread with manure spreader onto cropland or forageland; and soil
incorporate.
Regardless of the method, you must have the sludge material analyzed for waste
constituents just as you would your lagoon water. The sludge will contain different
nutrient and metal values from the liquid. The application of the sludge to fields will be
limited by these nutrients as well as any previous waste applications to that field and crop
requirement. Waste application rates will be discussed in detail in Chapter 3.
When removing sludge, you must also pay attention to the liner to prevent damage.
Close attention by the pumper or drag-line operator will ensure that the lagoon liner
remains intact. If you see soil material or the synthetic liner material being disturbed, you
should stop the activity immediately and not resume until you are sure that the sludge can
be removed without liner injury. If the liner is damaged it must be repaired as soon as
possible.
Sludge removed from the lagoon has a much higher phosphorus and heavy metal content
than liquid. Because of this it should probably be applied to land with low phosphorus and
metal levels, as indicated by a soil test, and incorporated to reduce the chance of erosion.
Note that if the sludge is applied to fields with very high soil-test phosphors, it should be
applied only at rates equal to the crop removal of phosphorus. As with other wastes,
always have your lagoon sludge analyzed for its nutrient value.
6

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.

Mortality Management Methods
Indicate which method(s) will be implemented.
When selecting multiple methods indicate a primary versus secondary option.
Methods otherthan those listed must be approved by the State Veterinarian.
Primary Secondary Routine Mortality
Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal
El El death. The burial must be at least 300 feet from any flowing stream or public body of water
(G.S.106-403). The bottom of the burial pit should beat least one foot above the seasonal
high water table. Attach burial location map and plan.
EJ Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC
13B .0200.
Rendering at a rendering plant licensed under G.S. 106-168.7.
Complete incineration according to 02 NCAC 52C .0102.
❑ A composting system approved and permitted by the NC Department of Agriculture & Con-
sumer Services Veterinary Division(attach copy of permit). If compost is distributed off-farm,
additional requirements must be met and a permit is required from NC DEQ.
In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture& Consumer Services(G.S. 106-549.70).
Any method which, in the professional opinion of the State Veterinarian,would make possible
the salvage of part of a dead animal's value without endangering human or animal health.
(Written approval by the State Veterinarian must be attached).
Mass Mortality Plan
Mass mortality plans are required for farms covered by an NPDES permit. These plans are
also recommended for all animal operations. This plan outlines farm-specific mortality man-
agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup-
ports a variety of emergency mortality disposal options; contact the Division for guidance.
• A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated
when numbers of dead animals exceed normal mortality rates as specified by the State
Veterinarian.
• Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary
Division regulations and guidance.
• Mass burial sites are subject to additional permit conditions(refer to facility's animal
waste management system permit).
• In the event of imminent threat of a disease emergency, the State Veterinarian may enact
additional temporary procedures or measures for disposal according to G.S. 106-399.4.
