'_"nN waste from your animal facility must be land applied at a specified rate to prevent pollution
5�urface and/or groundwater. The plant nutrients in the animal waste should be used to
"•Pice the amount of commercial fertilizer required for the crops in the fields where the waste
to be applied. This waste utilization plan uses nitrogen as the limiting nutrient. Waste
ould 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. Always apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can utilize. Soil types are
important as they have different infiltration rates, leaching potentials, cation exchange
capacities, and available water holding capacities. Normally waste shall not be applied to land
eroding at greater than 5 tons per acre per year. With special precautions, waste may be
applied to land eroding at up to 10 tons per year. Do not apply waste on saturated soils,when
it is mining, or when the surface is frozen. Either of these conditions may result in runoff to
surface waters which is not allowed under DEM regulations. Wind conditions should also be
considered to avoid drift and downwind odor problems. To maximize the value of nutrients for
:rop production and to reduce the potential for pollution, the waste should be applied to a
:-rowing crop or applied to bare ground not more than 30 days prior to planting. Injecting the
yaste or disking will conserve nutrients and reduce odor problems.
"1 3e estimated acres needed to apply the animal waste is based on typical nutrient content for
A\ '•
� type of facility. Acreage requirements should be based on the waste analysis report from
= r waste management facility. Attached you will find information on proper sampling
> ., hniques, preparation, and transfer of waste samples to the lab for analysis,
This waste utilization plan, if carried out, meets the requirements for compliance with 15A
NCAC 211.0217 adopted by the Environmental Management Commission.

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.
1M There must be documentation in the design folder that the producer either owns or has
an agreement for use of adequate land on which to properly apply the waste. If the
producer does not own adequate land to properly dispose of waste, he/she shall provide
a copy of an agreement with a landowner who is within a reasonable proximity, allowing
him/her the use of the land for waste application. It is the responsibility of the owner of
the facility to secure an update of the Waste UtilizatiQn Plan when there is a change in
the operation, increase in the number of animals, method of utilization, or available land.
3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic
crop yields based on soil type, available moisture, historical data, climatic conditions,and
level of management, unless there are regulations that restrict the rate of application for
other nutrients.
4 Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land that is eroding at 5 or more tons, but less than 10 tons per acre
per year providing grass filter strips are installed where runoff leaves the field. (See
F©TG Standard 393-Filter Strip).
5 odors can be reduced by injecting the waste or disking after waste application. Waste
should not be applied when there is danger of drift from the Irrigation field.
6 When animal waste is to be applied on acres subject to flooding, it will be soil
incorporated on conventionally tilled cropland. When applied to conservation tilled crops
or grassland,the waste may be broadcast provided the application tion does not occur during
a season prone to flooding. (See"Weather and Climate in North Carolina"for guidance.)
i ate.
}�.E
:ss a 7 Liquid waste shall be alaplied at rates not to exceed the soil infiltration rate such that
.:
runoff does not occur offsite or to surface waters and in a method which does not cause
drift from the site during application. No ponding should occur in order to control odor or
flies.
8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the
surface is frozen.
Page 5

REQUIRED SPECIFICATIONS
(continued)
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
.g
damage from animal waste should also be considered.
Ser
i'
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 ever crop planted to take up released nutrients.
Waste shall not be applied more than 30 days prior to planting of the crop or forages
breaking dormancy.
11 Any new swine facility sited on or after October 1, 1995 shall comply with the following:
The outer perimeter of the land area onto which waste is applied from a lagoon that is a
component of a swine farm shall be at least 50 feet from any residential property
boundary and from any perennial stream or river(other than an irrigation ditch or canal.
Animal waste other than swine waste from facilities sited on or after October 1, 1995),
shall not be applied closer than 25 feet to perennial waters. (See Standard 393 - Filter
strips).
12
Animal waste shall not be applied closer than 100 feet to wells.
13
Animal waste shall not be applied closer than 200 feet of dwellings other than those
owned by the landowner.
14
Waste shall be applied in a manner not to reach other property and public right-of-ways.
15
Animal waste shelf not be discharged into surface waters, drainageways, or wetlands by
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 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, toil,sinks, etc_ shall
not be discharged into the animal waste management system.
Page e

REQUIRED SPECIFICATIONS
(continued)
17 A protective cover of appropriate vegetation will be established on all disturbed areas
(lagoon embankments, berms, pipe runs, etc.). Areas shall be fenced as necessary to
protect the vegetation. Vegetation such as trees, shrubs, and other woody species, etc.,
are limited to areas where considered appropriate. Lagoon areas should be kept mowed
and accessible. Berms and structures should be inspected regularly for evidence of
erosion, leakage or discharge.
18 If animal production at the facility is to be suspended or terminated, the owner is
responsible for obtaining and implementing a "closure plan" which will eliminate the
possibility of an illegal discharge, pollution and erosion.
19 Waste handling structures, piping pumps, reels, etc., should be inspected on a regular
basis to prevent breakdowns, leaks and spills. A regular maintenance checklist should
be kept on site.
20 Animal waste can be used in a rotation that includes vegetables and other crops for
direct human consumption, However, if animal waste Is used on crops for direct human
consumption it should only be applied pre-plant with no further applications animal waste
during the crop season.
21 Highly visible markers shall be installed to mark the top and bottom elevations of the
temporary storage (pumping volume) of all waste treatment lagoons. Pumping shall be
managed to maintain the liquid level between the markers. A marker will be required to
mark the maximum storage volume for waste storage ponds.
22 Waste shall be tested within 60 days of utilization and soil shall be tested at least
annually at crop sites where waste products are applied. Nitrogen shall be the rate-
determining element. Zinc and copper levels in the soil shall be monitored and
alternative crop sites shall 'be used when these metal approach excessive levels. pH
shall be adjusted for optimum crop production and maintained. Soil and waste analysis
records shall be kept for five years. Poultry dry waste application records shall be
maintained for three (3) years. Waste application records for all other waste shall be
maintained for five(6)years.
23 Dead animals will be disposed of in a manner that meets North Carolina regulations.

Mortality Aanagement Methods
Indicate which method(s)will be implemented.
When selecting multiple methods indicate a primary versus secondary option.
Methods other than 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
death. The burial must be at least 300 feet from any flowing stream or public body of water
(G.S.106-443). The bottom of the burial pit should be at least one foot above the seasonal
high water table. Attach burial location map and plan.
Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC
13B.0200.
Rendering at a rendering plant licensed under G.S. 106-168.7.
QComplete 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.
�7 In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
u NC Department of Agriculture&Consumer Services(G.S, 106-549.70),
D ("� 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.

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 trade to
malntWn the lagoon close to the minimum liquid level as long as the weather and waste
utilization plan will allow it.

law and subject to penalty action.

routine maintenance of a lagoon involves the following:
Maintenance of a vegetative cover for the dam.
F d i' 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 comb-inatlon 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:
µ' 1. separation of joints
' 2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes
-e`

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
pe
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 sidew,311,-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
of these features, you should call an appropriate expert familiar with design and
-istruction of waste lagoons. You may need to provide a temporary fix if there is a threat
waste discharge' . However, a permanent solution should be reviewed by the
expert. Any digging into a lagoon dam with heavy equipment is a serious
with potentially serious consequ s ence and should not be conducted unless
-4mmended by an appropriate technical expert:
Transfer Pumps—check for proper operation of:
1. recycling pumps
2. irrigation pumps
ck for leaks, loose fittings, and overall pump operation. An unusually loud or grinding
'Jise, 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'e' q­uipment 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
_,n

xx
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 appropidate 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
Dave an inflow problem from a surface water diversion or there may be seepage into the
lagoon from the surrounding land.
Lagoon Operation
Stai tup:
�a
r.
1. Immediately after construction establish a complete sod cover on bare soil
11.� -•. 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 cheek on the lagoon liquid pH. If the pH falls below
7.0, add agricultural lime at the rate of l 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:
r;
e more frequently and regularly that wastewater- is added to a lagoon, the better- the
f° oon Will function. ta
. tes into the lagoon several dines daily are
t;timurn for treatment. pit recharge systems, in which one or more buildings are drained
`, recharged each day, also work well.

Practice water conservation---minimize building water usage and
spillage from leaking waterers, broken pipes and washdown through
proper maintenance and water conservation.
Minimize feed wastage and spillage by keeping feeders adjusted. This
will reduce the amount of solids entering the lagoon
Management:
Maintain lagoon liquid level between the permanent storage level and
the full temporary storage level,
Place visible markers or stakes on the lagoon bank to show the
minimum liquid level and the maximum liquid lever (Figure 2-1).
Start irrigating at the earliest possible date in the spring based on
nutrient requirements and soil moisture so that temporary storage
will be maximized for the summer thunderstorm season. Similarly,
irrigate in the late summer/early fall to provide maximum lagoon
storage for the winter.
The lagoon liquid level should never be closer than 1 foot to the lowest
point of the dam or embankment.
Do not pump the lagoon liquid level lower that the permanent storage
level unless you are:removing sludge.
Locate float pump intakes approximately 18 inches underneath the liquid
surface and as far away from the drainpipe inlets as possible.
Prevent additions of bedding materials, long-stemmed forage or vegetation,
molded feed, plastic syringes, or other foreign materials into the lagoon.
Frequently remove solids from catch basins at end of confinement houses or
wherever they are installed.
Maintain strict vegetation, rodent, and varmint control near lagoon edges.
Do not allow trees or large bushes to grow on lagoon dam or embankment.
Remove sludge from the lagoon either when the sludge storage capacity is
full or before it fills 50 percent of the permanent storage volume.
If animal production is to be terminated the owner is responsible for
obtaining and implementing a closure plan to eliminate the possibility of a
pollutant discharge.
8=tldge Removal:
9 e 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..
' ,agoon 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.
?moval techniques:
j„ Hire a custom applicator.
"s"a 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
ruirement. Waste application rates will.be discussed in detail in.Chapter 3.
,,% hen removing sludge, you must also pay attention to the liner to prevent damage. Close
= pntion by the pumper or drag-line operator will ensure that the lagoon liner remains
_a If you see soil material or the synthetic liner material being disturbed, you should
yy,=. the activity immediately and not resume until you are sure that the sludge can be
•oved without liner injury. If the liner is damaged it must be repaired as soon as
`ge removed from the lagoon has a much higher phosphorus and heavy metal content
p liquid. Because of this it should probably be applied to land with low phosphorus
«':. . metal levels, as indicated by a soil test, and incorporated to reduce the chance of
. �sion. 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.

'Possible Causes of Lagoon Failure
7..agoon failures result in the unplanned discharge of wastewater from the structure.. Types
>f failures include leakage through the bottom or sides, oveopping, and bech of the
`",Am. Assuming proper design and construction, the owner has the responsibility for
` lsuring 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.
