OPERATION AND MAINTENANCE PLAN .
---------------------------
This lagoon is designed for waste treatment with minimum odor
control. The time required for the planned fluid level to be
reached may vary due to soil conditions,flushing operations, and
the amount of fresh water added to the system.
Land application of waste water is recognized as an acceptable
method of disposal. Methods of application include solid set,
center pivot, guns, and traveling gun irrigation. Care should be
taken when applying waste to prevent runoff from the field or 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.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see Attachment B)
before land application.
3. Begin pump-out of the lagoon when fluid level reaches eleva-
tion 42.1 as marked by permanent markers. Stop pump-out when
the fluid level reaches elevation 40.2 or before fluid depth is
less than 6 feet deep (this prevents the loss of favorable
bacteria) .
4. The recommended maximum amount to apply per irrigation is
one (1) inch and the recommended maximum application rate is 0.4
inch per hour.
S. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
6. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable
outlets.
8. 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.

SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS
----------------------------------------------------------
Clearing:
All trees and brush shall be removed from the construction area
before any excavating or fill is started. Stumps will be removed
within the area of the foundation of the embankment and fill areas
and all excavated areas. All stumps and roots exceeding one (1)
inch in diameter shall be removed to a minimum depth of one (1)
foot. Satisfactory disposition will be made of all debris. The
foundation area shall be loosened thoroughly before placement of
embankment material.
Cut-off Trench:
---------------
A cut-off trench (when specified) shall be installed as shown in
the plans.
Construction:
-------------
Construction of excavated and earthfill areas shall be performed to
the neat lines and grades as planned. Deviations from this will
require prior approval of the SCS. Earthfill shall not be placed
in standing water and reasonable compaction of the fills shall be
performed by the construction equipment or sheeps-foot roller during
placement. The embankment of the lagoon shall be installed using
the more impervious materials. Construction of fill heights shall
include ten (10) percent for settlement. To protect against seepage,
when areas of unsuitable material are encountered, they will need to
be excavated a minimum of one (1) foot below grade and backfilled and
compacted with a suitable material (ie-CL,SC,CH) . Refer to the soils
investigation information in the plans for special considerations.
Precautions should be taken during construction to prevent excessive
erosion and sedimentation.
Vegetation:
All exposed embankment and other bare constructed areas shall be
seeded to the planned type of vegetation as soon as possible after
construction.

EMERGENCY ACTION PLAN
Using this outline as guidance, you should develop a specific emergency action plan for
your waste handling system. This. plan will be implemented in the event that wastes from
your operation are leaking, overflowing, or running off the site. You should NOT wait
until wastes reach surface waters or leave your property to consider that you have a
problem. You should make every effort to ensure that this does not happen. This plan
should be available to all employees at the facility, as accidents, leaks, and breaks could
happen at any time. Your plan should follow this format:
1. Stop the release of wastes. Depending on the situation, this may or
may not be possible. Suggested responses to problems are listed below:
a. Lagoon overflow—possible solutions are:
add soil to berm to temporarily increase elevation of dam—any
permanent alteration of the dam should be approved by a
qualified technical specialist
pump wastes to field at an acceptable rate
stop all additional flow to the lagoon (waterers)—hold waste in
house if possible
call a pumping contractor
make sure no surface water is entering lagoon
NOTE: These activities should be started when your lagoon level has exceeded the
temporary storage level.
b. Runoff from waste application field—actions include:
immediately stop waste application
create a temporary diversion or berm to contain the waste on
the field
incorporate waste to reduce further runoff
C. Leakage from the waste distribution system:
pipes and sprinklers—actions include:
— stop recycle (flushing system) pump
— stop irrigation pump
— close valves to eliminate further discharge
separate pipes to create an air gap and stop flow
flush system, houses, solids separators—actions include:
— stop recycle (flushing system) pump
— stop irrigation pump
— make sure no siphon effect has been created
separate pipes to create an air gap and stop flow
d. Leakage from base or sidewalI of lagoon. Often these are seepage as
opposed to flowing leaks—possible action*:
dig a small well or ditch to catch all seepage, put in a
submersible pump, and pump back into lagoon
if holes are caused by burrowing animals,trap or remove
animals and fill holes and compact with a clay type soil
other holes may be likewise temporarily plugged with clay soil
*Lagoon problems require the consultation of an individual
experienced in the design and installation of lagoons for permanent
repair measures.

2. Assess the extent of the spill and note any obvious damages.
a. Did the waste reach any surface waters?
b. Approximately how much was released and for what duration?
C. Any damage notes, such as employee injury,fish kills, or property
damage?
3. Contact appropriate agencies.
a. During normal business hours, call your DEM regional office, at
910-395-3900, after hours, emergency number: 919-733-3942.
Your phone call should include: your name, facility, telephone
number, the details of incident from item 2 above, the exact
location of the facility, and the location or
direction of movement of the spill, weather and wind
conditions, what corrective measures have been under taken,
and the seriousness of the situation.
b. If spill leaves, or is likely to leave, property or enters surface
waters, call local emergency management services (EMS) at 910-296-
2160.
C. Instruct EMS to contact local Health Department.
d. Contact local Soil and Water Conservation District
Natural Resources Conservation Service office at 910-296-2121,
and Cooperative Extension Service at 910-296-2143for
advice/technical assistance.
e. If you are a contract swine grower associated with a swine company
integrator, contact the company representative.
4. Implement procedures as advised by DEM and technical assistance
agencies to rectify the damage, repair the system, and reassess the
waste management plan to keep problems with release of wastes from
happening again.

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

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

Identified problems should be corrected promptly. It is advisable to inspect your system
during or immediately following a heavy rain. If technical assistance is needed to
determine proper solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then
record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will
give you an idea of how much your lagoon level will rise with a certain rainfall amount
(you must also be recording your rainfall for this to work). Knowing this should help in
planning irrigation applications and storage. If your lagoon rises excessively, you may
have an inflow problem from a surface water diversion or there may be seepage into the
lagoon from the surrounding land.
Lagoon Operation
Startup:
1. Immediately after construction establish a complete sod cover on bare soil
surfaces to avoid erosion.
2. Fill new lagoon design treatment volume at least half full of water before
waste loading begins, taking care not to erode lining or bank slopes.
3. Drainpipes into the lagoon should have a flexible pipe extender on the
end of the pipe to discharge near the bottom of the lagoon during initial
filling or another means of slowing the incoming water to avoid erosion of
the lining.
4. When possible, begin loading new lagoons in the spring to maximize
bacterial establishment (due to warmer weather).
5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon
liquid volume. This seeding should occour at least two weeks prior to the
addition of wastewater.
6. Maintain a periodic check on the lagoon liquid pH. If the pH falls below
7.0, add agricultural lirne at the rate of 1 pound per 1000 cubic feet of
lagoon liquid volume until the pH rises above 7.0. Optimum lagoon liquid
pH is between 7.5 and 8.0.
7. A dark color, lack of bubbling, and excessive odor signals inadequate
biological activity. Consultation with a technical specialist is recommended
if these conditions occur for prolonged periods, especially during the warm
season.
Loading:
The more frequently and regularly that wastewater is added to a lagoon, the better the
lagoon will function. Flush systems that wash waste into the lagoon several times daily are
optimum for treatment. Pit recharge systems, in which one or more buildings are drained
and recharged each day, also work well.

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

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

The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface water and/or groundwater. The piart nutrients in the animal waste should be used
to reduce the amount of commercial fertilizer required for the crops in the fields where the waste
is to be applied.
This waste utilization plan uses nitrogen as the limiting nutrient Waste should be analyzed
before each application cycle. Annual soil tests are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe manner.
1 Always apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can utilize
2 Soil types are important as they have different infiltration rates,leaching potentials,
cation exchange capacities,and available water holding capacities
3 Normally waste shall be applied to land eroding at less than 5 tons per acre per
year. Waste may be applied to land eroding at 5 or more tons per acre annually,but
less than 10 tons per acre per year providing that adequate filter strips are established
4. Do not apply waste on saturated soils,when it is raining,or when the surface is frozen
Either of these conditions may result in runoff to surface waters which is not allowed
under DWR regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor
problems.
8 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 Nutnent 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 addiligtial waste to be applied Provisions shall be made for the area receiving waste to
be flewble so as to accommodate changing waste analysis content and crop type Lime must
be applied to maintain pH in the optimum range for specrfc crop production
This waste utilization plan,if carried out,meets the requirements for compliance vnlh 15A NCAC

This plan does not include commercial fertilizer. The farm should produce adequate plant
available nitrogen to satisfy the requirements pf 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 nutrent
management plan that addresses all nutrients. This plan only addresses nitrogen
In interplanted fields(i.e.small grain,etc,interseeded in bermuda),forage must be removed
through grazing,hay,and/or silage. Where grazing,plants should be grazed when they
reach a height of six to nine inches. Cattle should be removed when plants are grazed to a
height of four inches. In fields where small grain,etc,is to be removed for hay or silage,care
should be exercised not to let small grain reach maturity,especially late in the season(i e
April or May). Shading may result if small grain gets too high and this will definitely interfere
with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen
being utilized Rather than cutting small grain for hay or silage just before heading as is
the normal situation,you are encouraged to cut the small grain earlier. You may want to
consider harvesting hay or silage two to three times during the season,depending on the
time small grain is planted In the fall.
The ideal lime to interplant small grain,etc,is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

The waste utilization plan must contain provisions for periodic land application of sludge at
agronomic rates The sludge wiil be nutrient rich and will require precautionary measures to
prevent over application of nutrients or other elements Your production facility wili produce
approximately 1462 pounds of plant available nitrogen per year and will accumulate in the lagoon
sludge based on the rates of accumulation listed above
If you remove the sludge every 5 years,you will have approximately 7310 pounds of plant
available nitrogen to utilize. Assuming you apply this PAN to hybrd bermuda grass hayland at the
rate of 300 pounds of nitrogen per acre,you will need 24 acreas of land. If you apply the sludge
to corn at a rate of 125 pounds per acre,you will need 55.48 acres of land Please note that these
are only estimates of the PAN produced and tha land required to utilize that PAN. Actual values
may only be determined by sampling the sludge for plant available nitrogen content prior to application
Actual utilization rates will vary with soil type,crop,and realistic yield expectations for the specific
application fields designated for sludge application at time of removal
APPLICATION OF WASTE BY IRRIGATION:
The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation
such that runoff or ponding occurs This rate is limited by initial soil moisture content,soil
structure,soil texture,water droplet size,and orgarrc 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 p'an,it is the responsibility of the
producer and igigation designer to ensure that an imgation system is installed to properly
irrigate the acres shown m the preceding table- Failure to apply the recommended rates and
amounts of nitrogen shown in the tables may make this plan invalid
,'This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. In many situations,the application
amount shown cannot be applied because of the nitrogen limitation. The maximum
application amount shown can be applied under optimum soil conditions
Your facility is designed for>180 days of temporary storage and the temporary storage must
be removed on the average of once every 6 months. In no instance should the volume of the
waste stored in your structure be within the 25 year 24 hour storm storage or one foot of
freeboard except in the event of the 25 year 24 hour storm
It is the responsibility of the producer and waste applicator to ensure that the spreader equipment
is operated properly to apply the correct rates to the acres shown in the tables. Failure to apply
the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid
Call your technical specialist after you receive the waste analysis report for assistance in
determining the amount of waste per acre and the proper application prior to applying the waste

Updated Crop Management Practices for Bermuda Winter Overseed
This document, as approved by the Interagency Nutrient Management Committee on
October 10, 2017, hereby modified the July 13, 1998 Memorandum"Crop Management
Practices for Select Forages Used in Waste Management". This modification updates
the application window protocol for the 100 lb Nitrogen PAN rate for both Cereal Rye
and Annual Ryegrass, as well as winter small grains.
• Farms utilizing the 100 lbs./ac PAN rate for the overseed are allowed to apply no
more than 50 lbs./ac PAN from October 1 through December 31 and no more than
50 lbs./ac PAN from January 1 through March 31.
• Applieations made during the months of December and January cannot exceed the
combined total of 25 lbs./ac PAN for the two-month period.
• The last application of animal waste is to be applied to the bermuda crop prior to
September 30.
• The PAN rate for grazed systems must be reduced by 25%.
All other requirements of the July 13, 1998 Memorandum continue to apply. Those
requirements include but are not limited to:
• Cereal rye and annual ryegrass should be planted by October 15 to provide the best
opportunity to get winter growth.
• A harvest is required prior to heading or April 7, whichever comes first, for both
cereal rye and annual ryegrass. This is necessary to minimize the potential for
shading of emerging bermuda and reducing its yield, To favor the production of
bermuda, additional harvest of annual ryegrass will be required when the ryegrass
canopy reaches 12-15 inches height.
•
These management requirements shall also apply to overseeded winter small grain.
