Application Method:
Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface water and/or groundwater. The plant nutrients in the animal waste should be used
to reduce the amount of commercial fertilizer required for the crops in the fields where the waste
is to be applied.
This waste utilization plan uses nitrogen as the limiting nutrient. Waste should be analyzed
before each application cycle. Annual soil tests are strongly encouraged so that all plant
iutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe manner:
1. Always apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can utilize.
2. Soil types are important as they have different infiltration rateer, leaching potentials,
cation exchange capacities, and available water holding capacities.
3. Normally waste shall be applied to land eroding at less than 5 tons per acre per
year. Waste may be applied to land eroding at 5 or more tons per acre annually, but
less than 10 tons per acre per year providing that adequate filter strips are established.
4. Do not apply waste on saturated soils, when it is raining, or when th@-Wace is frozen.
Either of these conditions may result in runoff to surface waters which is not allowed -
under DWQ regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor
Page: 1

problems.
6. To maximize the value of the nutrients for crop production and to reduce the potential
for pollution, the waste should be applied to a growing crop or applied not more than
30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or
disking will conserve nutrients and reduce odor problems.
This plan is based on the waste application method shown above. If you choose to change
methods in the future, you need to revise this plan. Nutrient levels for different application
methods are not the same.
The estimated acres needed to apply the animal waste is based on typical nutrient content
for this type of facility. In some cases you may want to have plant analysis made, which could
allow additional waste to be applied. Provisions shall be made for the area receiving waste to
be flexible so as to accommodate changing waste analysis content and crop type. Lime must
be applied to maintain pH in the optimum range for specific crop production.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
2H .0217 adopted by the Environmental Management Commission.
—,..AMOUNT OF WASTE PRODUCED PER YEAR ( gallons, ft3, tons, etc.):
3520 animals X 986 gat/animal/year =
AMOUNT OF PLANT AVAILABLE NITROGEN PRODUCED PER YEAR (Ibs):
3520 animals X 2.30 Ibs/animal/year =
3,468,960 gallons
8,096.00 Ibs
Applying the above amount of waste is a big job. You should plan time and have appropriate
equipment to apply the waste in a timely manner.
The following acreage will be needed for waste application based on the crop to be grown,
soil type, and surface application.

Indicates that this field is being overseeded (i.e. interplanted) or winter annuals follow summer
annuals.
`A negative number reflects the total Ibs of additional nitrogen needed to achieve yields on
acreage listed in chart. A positive number means additional acreage is required to utilize the
nitrogen produced by the farm.
NOTE:
This plan does not include commercial fertilizer. The farm should produce adequate plant
available nitrogen to satisfy the requirements of the crops listed above.
The applicator is cautioned that P and K may be over applied while meeting the N requirements.
In the future, regulations may require farmers in some parts of North Carolina to have a nutrient
management plan that addresses all nutrients. This plan only addresses nitrogen.
In interplanted fields ( i.e. small grain, etc, interceded in bermuda), forage must be removed
through grazing, hay, and/or silage. Where grazing, plants should be grazed when they
reach a height of six to nine inches. Cattle should be removed when plants are grazed to a
height of four inches. In fields where small grain, etc, is to be removed for hay or silage, care
should be exercised not to let small grain reach maturity, especially late in the season (i.e.
April or May). Shading may result if small grain gets too high and this will definately interfere
with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen

being'utilized. Rather than cutting small grain for hay or silage just before heading as is
the' normal situation, you are encouraged to cut the small grain earlier. You may want to
consider harvesting hay or silage two to three times during the season, depending on the
time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

Acres shown in the preceding table are considered to be the usable acres excluding
required buffers, filter strips along ditches, odd areas unable to be irrigated, and perimeter areas
not receiving full application rates due to equipment limitations. Actual total acres in the fields
listed may, and most likely will be, more than the acres shown in the tables.
See attached map showing the fields to be used for the utilization of animal waste.
SLUDGE APPLICATION:
The waste utilization plan must contain provisions for periodic land application of sludge at
agronomic rates. The sludge will be nutrient rich and will require precautionary measures to
prevent over application of nutrients or other elements. Your production facility will produce
approximately 0.36 pounds of plant available nitrogen per animal per year in the
sludge based on the application method listed earlier.
,If you remove the sludge every 5 years, you will have approximately 6336.00
Page: 4

pounds of PAN to utilize. Assuming you apply this PAN to hybrid bermudagrass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 21.12 acres of land. If you apply
the sludge to corn at a rate of 125 pounds per acre, you will need 50.69 acres of land.
°lease be aware that these are only estimates of the PAN and land needed. Actual requirements
could vary by 25% depending on your sludge waste analysis, soil types, realistic yields, and
applications.
APPLICATION OF WASTE BY IRRIGATION:
The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation
such that runoff or ponding occurs. This rate is limited by initial soil moisture content, soil
structure, soil texture, water droplet size, and organic solids. The application amount should not
exceed the available water holding capacity of the soil at the time of irrigation nor should the
plant available nitrogen applied exceed the nitrogen needs of the crop.
If surface irrigation is the method of land application for this plan, it is the responsibility of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in the preceding table. Failure to apply the recommended rates and
amounts of nitrogen shown in the tables may make this plan invalid.

*This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. In many situations, the application
amount shown cannot be applied because of the nitrogen limitation. The maximum
application amount shown can be applied under optimum soil conditions.
Your facility is designed for 180 days of temporary storage and the temporary storage must
be removed on the average of once every 6 months. In no instance should the volume of the
-. waste stored in your structure be within the 25 year 24 hour storm storage or one foot of

It is the responsiability of the producer and waste applicator to ensure that the spreader equipment
Is operated properly to apply the correct rates to the acres shown in the tables. Failure to apply
the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid.
Call your technical specialist after you receive the waste analysis report for assistance in
determining the amount of waste per acre and the proper application prior to applying the waste.

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
1• Animal waste shall not reach surface waters of the state by runoff, drift, manmade
conveyances, direct application, or direct discharge during operation or land
application. Any discharge of waste which reaches surface water is prohibited.
Illegal discharges are subject to the assessment of civil penalities of $10,000 per day
by the Division of Environmental Management for every day the discharge continues.
2. The Field Office must have documentation in the design folder that the producer
either owns or has long term access to adequate land on which to properly apply the
waste. If the producer does not own adequate land to properly dispose of waste, lie
shall provide NRCS with a copy of a written agreement (sample enclosed) with a
landowner who is within a reasonable proximity, allowing him/her the use of the land
for waste application for the life expectancy of the production facility. It is the
responsibility 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, climate
conditions, and level of, management, unless there are regulations, that restrict the
rate of application for other nutrients.
4. Animal waste may be applied to land that has a Resource Management System
(RMS) or an Alternative Conservation System (ACS). If an ACS is used the soil loss
shall be no greater than 10 tons per acre per year and appropriate filter strips will
Abe used where runoff leaves the field. These filter strips will be in addition to
Buffers requried by DEM. [See FOTG Standard 393 -- Filter Strips and Standard
390 (Interim) -- Riparian Forest Buffers.]
5. Odors can be reduced by injecting the waste or disking after waste application.
Waste should not be applied when the wind is blowing.
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 conservaton 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" in the Technical Reference -- Environment file 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 conditions conducive to odor or flies and provide uniformity of application.

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
(continued)
8. 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 no
more than 20 to 25 percent of the leaf area is covered by solids.
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
on bare soil.
11. Animal waste shall not be applied closer than 25 feet to surface water. This distance
may be reduced for waters that are not perennial provided adequate vegetative filter
strips are present. (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
wetlands provided they have been approved as a land application site by a "technical
specialist". Animal waste should not be applied on grassed waterways that discharge
directly into water courses, and only then at agronomic rates provided the application
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. Lagoons and other uncovered waste containment structures must maintain a
maximum operating level to provide adequate storage for a 25-year, 24-hour storm
event in addition to the one (1) foot mandatory freeboard.

WASTE UTILIZATION PLAN
REQUIRED SPECIFICATIONS
(continued)
18. A protective cover of appropriate vegetation will be establised on all disturbed areas
(lagoon embankments, berms, pipe runs, etc.). If needed, special vegetation shall be
provided for these areas and shall be fenced, as necessary, to protect the vegetation.
Vegetation such as trees, shrubs, and other wooded species, etc. are limited to areas
where considered appropriate. Lagoon areas should be kept mowed and accessible.
Lagoon berms and structures should be inspected regularly for evidence of erosion,
leakage, or discharge.
19. 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.
20. 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.

KEEP THIS WITH YOUR CERTIFICATION AND OTHER WASTE MANAGEMENT
RECORDS
By January, 1997, all Carroll's company farms and grower farms will have a new addition in
their waste treatment lagoons -- a LIQUID LEVEL INDICATOR. Though simple in design,
this tool will go a long way in assisting all of us to better manage the liquid level in our
lagoons.
In order to complete the project this winter, Bruce Jones has been contracted by Carroll's
Foods to install indicators on grower farms. Using survey equipment and a boat, Bruce will
determine the lowest point of each dike and set the indicators at the correct elevation. The
indicators will be located in the most visible area of the lagoon and close to the irrigation
pump if possible. Each indicator will serve the following purposes:
1. SHOW THE MAXIMUM LIQUID LEVEL (This is the top pipe and is located below the 1
foot freeboard and 25 year 24 hour storm.) The newer indicators are painted red down
to the maximum liquid level. If the liquid is in the RED, the farm is out of compliance.
2. SHOW THE HALFWAY POINT (This is the middle pipe and is 1 foot below the
maximum level and 1 foot above the minimum or stop pumping level.) Waste
management operators are encouraged to utilize this level for pumping during the spring
and summer months. This will allow extra storage for periods of wet weather or
r- extremely heavy rains.
3. SHOW THE MINIMUM LEVEL (Stop pumping). This pipe will be 2 feet below the start
pumping elevation for most lagoons. Irrigating below this level will reduce waste
treatment and can result in odors and less breakdown of solids. It is strongly
recommended that all farms be at this level when going into the winter months.
Like most other management tools, the liquid level indicator is no better than the person who
uses it. If even one spill can be prevented, this effort will be worthwhile for the industry.

OPERATION AND MAINTENANCE PLAN
------------------------------
This lagoon is designed for waste treatment (permanent storage) and
180 days of temporary storage. The time required for the planned
fluid level (permanent and temporary storage) to be reached may vary
due to site conditions, weather, flushing operations, and the amount
of fresh water added to the system.
The designed temporary storage consists of 180 days storage for:
(1) waste from animals and (2) excess rainfall after evaporation. Also
included is storage for the 25 year - 24 hour storm for the location.
The volume of waste generated from a given number of animals will be
fairly constant throughout the year and from year to year, but excess
rainfall will vary from year to year. The 25 year rainfall will not
be a factor to consider in an annual pumping cycle, but this storage
volume must always be available.
A maximum elevation is determined in each design to begin
pumping and this is usually the outlet invert of pipe(s) from
building(s). If the outlet pipe is not installed at the elevation to
begin pumping, a permanent marker must be installed at this elevation
to indicate when pumping should begin. An elevation must be established
to stop pumping to maintain lagoon treatment depth.
Pumping can be started or stopped at any time between these two
elevations for operating convenience as site conditions permit, such as
weather, soils, crop, and equipment .in order to apply waste without
runoff or leaching.
Land application of waste water is recognized as an acceptable
method of disposal. Methods of application include solid set,
- center pivot,iguns, and traveling gun irrigation. Care should be
taken when applying waste to prevent damage to crops.
The following items are to be carried out:
1. It is strongly recommended that the treatment lagoon be pre -
charged to 1/2 its capacity to prevent excessive odors during
start-up. Pre -charging reduces the concentration of the initial
waste entering the lagoon thereby reducing odors. Solids should be
covered with effluent at all times. When precharging is complete,
flush buildings with recycled lagoon liquid. Fresh water should not
be used for flushing after initial filling.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see attachment)
before land application.
3. Begin temporary storage pump -out of the lagoon when fluid level
reaches the elevation 49.8 as marked by permanent marker. Stop pump -
out when the fluid level reaches elevation 47.6 . This temporary
storage, less 25 yr- 24 hr storm, contains 164974 cubic feet or
1234007 gallons.

SHEET 2 OF 2
4. The recommended maximum amount to apply per irrigation is
one (1) inch and the recommended maximum application rate is 0.3
inch per hour. Refer to the waste utilization plan for further details.
5. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain avigorous stand.
6. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable
outlets.
8. Keep a minimum of 25 feet of grass vegetated buffer around
waste utilization fields adjacent to perennial streams. Waste will
not be applied in open ditches. Do not pump within 200 feet of a
residence or within 100 feet of a well. Waste shall be applied in a
manner not to'reach other property and public right-of-ways.
r
9. The Clean Water Act of 1977 prohibits the discharge of
pollutants into waters of the United States. The Department of
Environment, Health, and Natural Resources, Division of Environ-
mental Management, has the responsibility for enforcing this law.

PERATION & MAINTENANCE PLAN
proper lagoon liquid management should be a year-round priority- It is especially important to
manage levels so that you do not have problems during extended rainy and wet periods.
Maximum storage capacity should be available in the lagoon for periods when the receiving crop
is dormant such as wintertime for bermudagrass or when there are extended rainy spells such as
the thunderstorm season in the summertime• This means that at the first signs of plant growth in
the later winter/early spring, irrigation according to a farm waste management plea should be
done whenever the land is dry enough to receive lagoon liquid. This will make storage space
available in the lagoon for future wet periods. In thfora summer/early
effort should be should be
pumped down to the low marker to allow for winterg Every
ade to
maintain the lagoon close to the minimum liquid level as long as the weather and waste utilization
plan will allow it.
Waiting until the lagoon has reached its maximum storage capacity before starting to irrigate does
not leave room for storing excess water during extended wet periods. Overflow from the lagoon
for any reason except a 25-year, 24-hour storm is a violation of state law and subject to penalty
action.
LAGOON MAINTENANCE
The routine maintenance of a lagoon involves the following:
✓ Maintenance of a ve etative cover for the dam. Fescue or common bermudagrass are the
most common vegetative covers. The vegetation should be fertilized each year, if needed,
to maintain a vigorous stand. The amount of fertilizer applied should be based on a soils
test, but in the event that it is not practical to obtain a soils test each year, the lagoon
embankment and surrounding areas should be fertilized with 800 pounds per acre of
10-10-10, or equivalent.
✓ Brush and trees on the embankment must be controlled. This may be done by mowing,
spraying, grazing, chopping, or a combination of these practices. This should be done at
least once a year and possibly twice in years that weather conditions are favorable for
heavy vegetative growth.
NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter the
lagoon water. Such chemicals could harm the bacteria in the lagoon that are treating the waste.

Maintenance inspections of the entire lagoon should be made during the initial filling of the lagoon
and at least monthly and after major rainfall and storm events. Items to be checked should
include, as a minimum, the following:
✓ Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes --- look for:
1 . separation of joints
2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes
✓ Lagoon surface--- look for:
1. undesirable vegetative growth
2. floating or lodged debris
✓ Embankment--- look for:
1. settlement, cracking, or "jug" holes
2. side slope stability--- slumps or bulges
3. wet or damp areas on the back slope
4. erosion due to lack of vegetation or as a result of wave action
5. rodent damage
Larger lagoons may be subject to liner damage due to wave action caused by strong winds.
These waves can erode the lagoon side walls, 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 side wall, baffles in the lagoon may be used to reduce the wave
impacts.
Any of these features could lead to erosion and weakening of the dam. If your lagoon has any of
these features, you should call an appropriate expert -familiar with design and construction of
waste lagoons. You may need to provide a temporary fix if there is a threat of a waste discharge.
However, a permanent solution should be reviewed by the technical expert. Any digging into a
lagoon dam with heavy equipment is a serious undertaking with potentially serious consequences
and should not be conducted unless recommended by an appropriate technical expert.
Transfer Pumps --- check for proper operation of:
1 . recycling pumps
2. irrigation pumps
Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding noise,
or a large amount of vibration, may indicate that the pump is in need or repair or replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that
you are not completely "surprised" by equipment failure. You should perform your pumping
system maintenance at a time when your lagoon is at its low level. This will allow some safety
time should major repairs be required. Having a nearly full lagoon is not the time to think about

switching, repairing, or borrowing pumps. Probably, if your lagoon is full, your neighbor's lagoon
is full also. You should consider maintaining an inventory of spare parts or pumps.
Surface water diversion features are designed to carry all surface drainage waters
(such as rainfall runoff, roof drainage, gutter outlets, and parking lot runoff away
from your lagoon and other waste treatment or storage structures. The only water
that should be coming into your lagoon is that which comes from your flushing
(washing) system pipes and the rainfall that huts the lagoon directly. You should
inspect your diversion system for the following:
1. adequate vegetation
2. diversion capacity
3. ridge berm height
Identified problems should be corrected promptly. It is advisable to inspect your system during or
immediately following a heavy rain. If technical assistance is needed to determine proper
solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then record the
level again 4 to 6 hours after the rain (assumes there is no pumping). This will give you an idea of
how much your lagoon level will rise with a certain rainfall amount (you must also be recording
your rainfall for this to work). Knowing this should help in planning irrigation applications and
storage. If your lagoon rises excessively, you may have an inflow problem from a surface water
diversion or there may be seepage into the lagoon from the surrounding land.
Lagoon Operation
Startup:
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 mare 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
fimction. 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 wash down through proper maintenance and
water conservation.
Minimize feed wastage and spillage by keeping feeders adjusted. This will reduce
the amount of solids entering the lagoon
Management:
✓ Maintain lagoon liquid level between the permanent storage level and the full temporary
storage level.
✓ Place visible markers or stakes on the lagoon bank to show the
minimum liquid. level and the maximum liquid lever (Figure 2- 1).
✓ Start irrigating at the earliest possible date in the spring based on nutrient requirements
and soil moisture so that temporary storage will be maximized for the summer
thunderstorm season. Similarly, irrigate in the late summedearly fall, to provide maximum
lagoon storage for the winter.
✓ The lagoon liquid level should never be closer than 1 foot to the lowest point of the dam
or embankment.

-^ ✓ Do not pump the lagoon liquid level lower that the permanent storage level unless you are
removing sludge.
✓ Locate float pump intakes approximately 18 inches underneath the liquid surface and as
far away from the drainpipe inlets as possible.
✓ Prevent additions of bedding materials, long-stemmed forage or vegetation, molded feed,
plastic syringes, or other foreign materials into the lagoon.
✓ Frequently remove solids from catch basins at end of confinement houses or wherever they
are installed.
✓ Maintain strict vegetation, rodent, and varmint control near lagoon edges. Do not allow
trees or large bushes to grow on lagoon dam or embankment.
✓ Remove sludge from the lagoon either when the sludge storage capacity is full or before it
Os 50 percent of the permanent storage volume.
✓ If animal production is to be terminated, the owner is responsible for obtaining and
implementing a closure plan to eliminate the possibility of a pollutant discharge.
Sludge Removal:
Rate of lagoon sludge buildup can be reduced by:
proper lagoon sizing,
mechanical solids separation of flushed waste, gravity settling of flushed waste solids in an
appropriately designed basin, or
minimizing feed wastage and spillage.
Lagoon sludge that is removed annually rather than stored long term will:
• have more nutrients,
• have more odor, and
• require more land to properly use the nutrients.
Removal techniques:
• Hire a custom applicator.
._,,. Mix the sludge and lagoon liquid with a chopper -agitator impeller pump through
large -bore sprinkler irrigation system onto nearby cropland; and soli incorporate.

r-. Dewater the upper part of lagoon by irrigation onto nearby cropland or forage land; mix
• into liquid slud e applicator; haul and spread onto cropland or
remaining sludge; pumpg PP
forage land; and sod. incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forage land;
dredge sludge from lagoon with drag line 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 forage land; and soil incorporate.
Regardless of the method, you must have the sludge material analyzed for waste constituents just
values from
as you would your lagoon water. The sludge fields11contain different nutrients nutrient and as well as any
the liquid. The application of the sludge t
previous waste applications to that field and crop requirement.
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 phosphorus, it should be applied only at
rates equal to the crop removal of phosphorus. As with other wastes, always have your lagoon
sludge analyzed for its nutrient value.
The application of sludge will increase the amount of odor at the waste application site. Extra
precaution should be used to observe the wind direction and other conditions which could
increase the concern of neighbors.
Possible Causes of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure. Types of
failures include leakage through the bottom or sides, overtopping, and breach of the dam
Assuming proper design and construction, the owner has the responsibility for ensuring structure
safety. Items which may lead to lagoon failures include:
Modification of the lagoon structure --- an example is the placement of a pipe in
the dam without proper design and construction. (Consult an expert in lagoon
design before placing any pipes in dams.)
Lagoon liquid levels--- high levels are a safety risk.

Failure to inspect and maintain the dam
Excess surface water flowing into the lagoon.
Liner integrity--- protect from inlet pipe scouring, damage during- sludge
removal, or rupture from lowering lagoon liquid level below groundwater table.
NOTE: if lagoon water is allowed to overtop the dam, the moving water will soon cause
gullies to form in the dam Once this damage starts, it can quickly cause a large discharge of
wastewater and possible dam failure.

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 ofpull. 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.

MEMORANDUM
TO: All Prospective Contract Growers
FROM: Don Butler, Real Estate Manager
Howard Hobson, Resource Conservationist
RE: Legal requirements fok swine growers in
North Carolina and how they relate to you
The facility design and waste management plan attached is of the utmost importance to
you and to Carroll's. This plan must be approved by a technical specialist with USDA -
Natural Resource Conservation Service prior to construction start. The lagoon must be
constructed exactly as designed unless changes are approved by the original designer and
NRCS personnel. The approved plan needs to become a part of your permanent records
and must be readily available for review if and when your farm is inspected by state
regulatory personnel.
When earthwork and lagoon construction is complete and the top of the dike and
outside slopes of the lagoon have been graded, seeded, and fertilized it must pass a final
inspection by NRCS personnel in order for your farm to be certified ready to stock
animals. At the time of final construction approval, the owner and the person certifying
construction' must sign a document called "Certification for New or Expanded Animal
Feedlots" (a' blank of this form is enclosed in your package) and this form must be sent
to the Department of Environmental Health and Natural Resources in Raleigh. Copies
of the signed document should be kept in your permanent file, one copy goes to NRCS
for their file, and a copy must be presented to Carroll's Foods before any animals can
be placed on' your farm. The owner is responsible for the Certification being completed
and sent to the appropriate places. Remember, NO CERTIFICATION -- NO ANIMALS.
If you have any questions about the above information, please contact one of
us by calling 910-293-3434, extension 246.

SHEET 1 OF 2
SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS
----------------------------------------------------------
FOUNDATION PREPARATION:
-----------------------
The foundation area of the lagoon embankment and building pad shall be
cleared of trees, logs, stumps, roots, brush, boulders,sod and rubbish.
Satisfactory disposition will be made of all debris. The topsoil from
the lagoon and pad area should be stripped and stockpiled for use on
the dike and pad areas. After stripping, the foundation area of the
lagoon embankment and building pad shall be thoroughly loosened prior
to placing the first lift of fill material to get a good bond.
EXCAVATION AND EARTHFILL PLACEMENT:
------------- =---------------------
The completedlexcavation and earthfill shall conform to the lines,
grades, and elevations shown on the plans. Earthfill material shall
be free of material such as `sod, roots, frozen soil, stones over
6 inches in diameter, and other objectionable material: To the extent
they are suitable, excavated materials can be used as fill. The fill
shall be brought up in approximately horizontal layers not to exceed 9
inches in thickness when loose and prior to compaction. Each layer
will be compacted by complete coverage with the hauling and spreading
equipment or standard tamping roller or other equivalent method.
Compaction will be considered adequate when fill material is -observed
to consolidate to the point that settlement is not readily detectible.
NOTE THE SPECIAL REQUIREMENTS FOR PLACEMENT OF LINERS IN THE LINER
SECTION OF THIS SPECIFICATION. The embankment of the lagoon shall be
installed using the more impervious materials from the required
excavations. Construction of fill heights shall include 5 percent for
settlement. Dikes over 15 feet in height and with an impoundment
capacity of 10 acre-feet or more fall under the jurisdiction of the NC
Dam Safety Law. The height is defined as the difference in elevation
from the constructed height to the downstream toe of the dike.
Precautions shall be taken during construction to prevent excessive
erosion and sedimentation.
LINER: THE MINIMUM REQUIRED THICKNESS SHALL BE 1.8 ft.
------ -------------------------------------------------
NOTE: LINERS (PARTIAL OR FULL) ARE REQUIRED WHEN THE ATTACHED SOILS
INVESTIGATION REPORT SO INDICATES OR WHEN UNSUITABLE MATERIAL IS
ENCOUNTERED DURING CONSTRUCTION. A TYPICAL CROSS SECTION OF THE LINER
IS INCLUDED IN THE DESIGN WHEN LINERS ARE REQUIRED BY THE SOILS REPORT.
When areas of unsuitable material are encountered, they will be over -
excavated below finish grade to the specified depth as measured
perpendicular to the finish grade. The foundation shall be backfilled
as specified to grade with a SCS approved material (ie - CL,SC,CH).
REFER TO THE SOILS INVESTIGATION INFORMATION IN THE PLANS FOR SPECIAL
CONSIDERATIONS.

SHEET 2 OF 2
-^ Soil liner material shall come from an approved borrow area. The
minimum water!content of the liner material shall be optimum moisture
content whichrelates to that moisture content when the soil is kneaded
in the hand it will form a ball which does not readily separate. Water
shall be added to borrow as necessary to insure proper moisture content
during placement of the liner. The moisture content of the liner
material shall not be less than optimum water content during placement.
The maximum .witer content relates to the soil material being too wet
for efficient!use of hauling equipment and proper compaction. Proper
compaction of?the liner includes placement in 9 inch lifts and
compacted to at least 90 percent of the maximum ASTM D698 Dry Unit
Weight of the liner material. When smooth or hard, the previous lift
shall be scarified and moistened as needed before placement of the next
lift.
The single most important factor affecting the overall compacted perme-
abilityof a clay liner, other than the type of clay used for the
i liner, s the efficient construction processing of the compacted liner.
The sequence'of equipment use and the routing of equipment in an estab-
lished pattern helps assure i.niformity in the whole placement and
compaction process. For most clay soils, a taming or sheepsfoot
roller is the!preferable type of compaction equipment.
The soil liner shall be protected from the discharge of waste outlet
pipes. This can be done by using some type of energy dissipator(rocks)
or using.flexible outlets on waste pipes.
Alternatives to soil liners are synthetic liners and bentonite sealant.
When these are specified, additional construction specifications are
included withthis Construction Specification.
CUTOFF TRENCH:
--------------
A cutoff trench shall be constructed under the embankment area when
shown on a typical cross section in the plans. The final depth of the
cutoff trench shall be determined by observation of the foundation
materials.
VEGETATION:
All exposed embankment and other bare constructed areas shall be seeded
to the planned type of vegetation as soon as possible after construc-
tion according to the seeding specifications. Topsoil should be placed
on areas of the dike and pad to be seeded. Temporary seeding or mulch
shall be used,if the recommended permanent vegetation is out of season
dates for seeding. Permanent vegetation should be established as soon
as possible during the next period of approved seeding dates.
REMOVAL OF EXISTING TILE DRAINS
-------------------------------
When tile drains are encountered, the tile will be removed to a minimum
of 10 feet beyond the outside toe of slope of the dike. The tile
trench shall be backfilled and compacted with good material such as
SC, CL, or CH:

IRRIGATION CALIBRATION
Irrigation rates are usually defined by a combination of pumping or flow rate,
Sprinkler nozzle diameter and operating pressure, sprinkler wetted diameter, sprinkler
spacing, and travel speed. Pumping rates are given by the manufacturers' data curves and
depend on the motor size and amperage drawn or pto operating speed, suction lift and
operating pressure. The greater the amps or pto speed, the higher the flow rate. Higher
suction lifts and/or operating pressures decrease the flow rate. Flow rates can only
practically be checked using in -line flow meters whose reliability in wastewater are
questionable or external Doppler -type flow meters which are expensive.
Stationary Sprinkler: Rotary -impact sprinkler nozzle discharge rates depend on
nozzle diameter and nozzle operating pressure (different from the pump pressure).
Manufacturers' data give flow rates for different nozzle diameters and pressures. Nozzles
can wear with age particularly if the wastewater has sand or grit, resulting in higher flow
rates or uneven distribution. Application rates depend on the wetted diameter, nozzle
type (taper -bore or ring), nozzle trajectory above ground, and sprinkler spacing or overlap.
Taper -bore nozzles provide larger droplet sizes covering more area and result in lower
application rates and less wind drift than ring nozzles. Higher trajectory sprinklers cover
less area resulting in higher application rates and more wind drift than low -trajectory
6-14.3

-4-
nozzles. Uniformity of application depends on sprinkler spacing and wind velocity.
Stationary sprinklers are usually spaced at 60% of their wetted diameter. To measure the
application rate and uniformity under station
ary sprinklers, a or
gauges can be equally spaced in two perpendicular transects under bthe er ofull- �cleess in rain
The container spacing should be no more than 10% of the wetted diameter. nAfter
irrigating for a specific time period, measure the depth of liquid in the containers (inches)
and divide by the operating time (hours) to get the application rate and uniformity of
application.
Traveling Sprinkler: Traveling sprinklers have the added variable of forward travel
speed affecting the application rate. Lane spacing for traveling sprinklers is normally 70-
75% of sprinkler wetted diameter for uniform overlap. Hose -reel travelers have
adjustable sprinkler travel speeds for varying the application rate which are charted on the
machine by the manufacturer. Since the empty hose reels at the beginning h of a sprinkler
pull have a smaller diameter, the sprinkler travel speed at the beginning of the pull will
slower than it is near the end of the pull when the hose reel is full and has a larger
diameter. Therefore, the application rate will be higher at the beginning of the pull than
at the end. To compensate for this difference, manufacturers are now putting speed
compensators on the hose -reel travelers to ensure the sprinkler travel is the same from
beginning to end. This device should be a must for all traveling wastewater irrigators. A
periodic check of the travel speed can be performed by painting a mark on the sprinkler
hose near the sprinkler. Place two stakes 100 feet apart near the hose at the beginning of
the Pull and again near the end of the pu1L Record the time it takes for the mark on the
hose to travel between the stakes and compare this actual travel speed with that specified
by the manufacturer.
Example : What travel speed is needed to a 1 0.5 inch with a 250-
250-ft lane spacing? pp Y gpm gun on a
travel speed, ft/min =
flow rate, gpm x 1.605
lane spacing, ft application depth, in
250 gpm x 1.605 - 250 ft — 0.5 in
3.2 ft/min

EMERGENCY ACTION PLAN
This plan will be implemented in the event that surfs a e fromwaters or leave your,propeoverflrty owsto consider you, or runs Off hhave
site. You should NOT waft until these waste reach
a problem. You should make every effort to ensure dthat this does breaks can happenofhap anytime.Thisplan should be available to
all employees at the facility, as accidents, le
1) Stop the release of waste. Depending on the situation, this may or may not be possible. Suggested
responses to problems are listed below: -
A) Lagoon Overflow:
* add soil to the berm to increase the elevation of the dam
* pump waste to fields at an acceptable rate
* stop all. additional flow to the lagoon
* call a pumping contractor
* make sure no surface water is entering the lagoon
Note. These activities should be started when your lagoon level has exceeded the temporary store a level.
B) Runoff from waste application field:
* immediately stop waste application
* create a temporary diversion or berm to contain the waste on the field
* incorporate waste to reduce further runoff
C1 Leaking from the waste distribution system:
• pipes and sprinklers:
1) stop recycle (flushing system) pump
2) stop irrigation pump
3) close valves to eliminate further discharge
4) separate pipes to create an air gap and stop flow
* flush system, houses, solid separators:
1) stop recycle (flushing system) pump
2) stop irrigation pump
3) make sure no siphon effect has been created
4) separate pipes to create an air gap and stop flow
D) Leakage from base or sidewall of the lagoon. Often these are seepage as opposed to flowing leaks:
'-� * dig a small well or ditch to catch all seepage, put in a submersible pump, and pump back into the lagoon
NCCES, WUP version 1, page 9

• if holes are caused by burrowing animals, trap or remove animals and fill holes with compacted clay type
soil
• other holes may be likewise temporarily plugged with clay soil
Note: For permanent repair measures, lagoon problems require the consultation of an individual experienced in
their design and installation.
2) Assess the extent of the spill and note any obvious damage.
A) Did the waste reach any surface waters?
8) Approximately how much was released and for what duration?
C) Any damage noted, such as employee injury, fish kills, or property damage?
3) Contact appropriate agencies.
A) During normal business hours, call your DEM regional office at: 9our 10-395.3900 : after hours, the emergency
number is: 919.733.3942 . Your phone call should
the Iocatlon or directiono the spill, II, weather and windhone number, the
of
the incident, t ie exact ocation of the facility,
conditions, what corrective measures have been taken, and the seriousness of the situation.
8) If the spill leaves the property or enters surface water, call the local EMS at: 911.
C) Instruct EMS to contact the local Health Department at: 910.640.6617 .
D) Also contact the following other agencies:
The Cooperative Extension Service at: 910.640-6605 .
Your local Soil and Water Conservation District at: 910.6 1=2.2348.
The local Natural Resources Conservation Service at: L10-642 -2348.
And your Integrator at. Ao�'o& vI 'a 4 3 -. s y
4) Implement procedures as advised by OEM and the technical assistance agencies to rectify the damage, repair
the system, and reassess the Waste Management Plan to keep problems with release of waste from happening
again.
