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
nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in the 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 not be applied to land eroding at more 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 in runoff to the surface waters which is not
allowed under DWQ regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor problems.
6. To maximize the value of the nutrients for crops 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 applications 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. Acreage requirements should be based on the waste analysis report from
your waste management facility. In some cases you may want to have plant analysis made, which
Rodney Hall Farm
Page 2
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 the 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.

Zone 4 has a Waste Utilization Agreement with nieghbor to apply waste on his land, and producer will
be using temporary pipe for this application.
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.
Rodney Hall Farm Page 3
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. interseeded in bermudagrass), 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 to reach materity,
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 the 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 mowed to a height of about two inches before drilling for best
results.
Caution must be exercised in grazing or haying summer annuals under stressed conditions. Nitrate poisoning
may occur in livestock. Sampling forage or hay for nitrate levels is recommended.
Acres shown in the tables are considered to be the usable acres excluding required buffers, filters 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 field 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 438 lbs. of plant available
nitrogen per year in the sludge.
If you remove sludge every 5 years you will have approximately 2189 lbs. of PAN to utilize. Assuming you
apply this PAN to hybrid bermudagrass hayland at the rate of 300 lbs/acre you will need 7
acres of land. If you apply the sludge to corn at the rate of 125 lbs. of nitrogen per acre you will need
acres of land. Please be aware that these are only estmates of the PAN and the land needed. Actual
requirements could vary by 25% depending on the sludge waste analysis, soil types, realistic yields, and
application methods.
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
Rodney Hall Farm Page 4
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 irrrigate the acres shown in tables.
Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan
invalid.
The following table is provided as a guide for establishing application rates and amounts.

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 limitations. 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 instances should the volume of the waste be 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 the waste applicator to ensure that the spreader equipment is operated
properly to apply the correct rates 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 have receive the waste analysis report for assistance in determining the
amount of waste per acre and the proper application rate prior to appling the waste.
NARRATIVE OF OPERATION
Rodney Hall Farm Page 6
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.
2. There must be documentation in the design folder that the producer either owns or has an
agreement for use of adequate land on which to properly apply 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 Utilization Plan when there is a change in the operation,
increase in the number of animals, method of utilization, or available land.
3. Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic crop
yields based on soil type, available moisture, historical data, climatic conditions, and level
of management, unless there are regulations that restrict the rate of application for other
nutrients.
4. Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land that is eroding at 5 or more tons, but less than 10 tons per acre per
year providing grass filter strips are installed where runoff leaves the field. (See FOTG
standard 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 does not occur during a season
prone to flooding. (See "Weather and Climate in North Carolina" for guidance.)
7. Liquid waste shall be applied at rates not to exceed the soil infiltration rate that runoff
does not occur offsite or to the 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.
9. Animal waste shall be applied on actively growing crops in such a manner that the crop is
not covered with waste to a depth that would inhibit growth. The potential for salt damage
from animal waste should also be considered.
10. Waste nutrients shall not be applied in fall or winter for spring planted crops on soils with a
high potential for leaching. Waste nutrient loading rates on these soils should be held to a
minimum and a suitable winter cover crop planted to take up released nutrients. Waste
shall not be applied more than 30 days prior to planting of the crop or forages breaking
dormancy.
11. Any new swine facility sited on or after October 1, 1995 shall comply with the following:
The outer perimeter of the land area onto which waste is applied from a lagoon that is a
component of a swine farm shall be at least 50 feet from any residential property boundary
and from any perennial stream or river (other than an irrigation ditch or canal. Animal
waste other than swine waste from facilities sited on or after October 1, 1995), shall not be
applied closer than 25 feet to perennial waters. (See Standard 393 - Filter Strips).
Rodney Hall Farm Page 7
REQUIRED SPECIFICATIONS
(continued)
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 he 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, drainage ways, 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 wash down facilities, showers, toilets, sinks, etc., shall
not be discharged into the animal waste management system.
17. A protective cover of appropriate vegetation will be established on all disturbed areas
(lagoon embankments, berms, pipe runs, etc.). Areas shall be fenced as necessary to
protect the vegetation. Vegetation such as trees, shrubs, and other woody species, etc.,
are limited to areas where considered appropriate. Lagoon areas should be kept mowed
and accessible. Berms and structures should be inspected regularly for evidences 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 vegetation 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 of animal waste
during the crop season.
21. Highly visible markers shall be installed to mark the top and the 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 (5) years. Poultry dry waste application records shall be maintained for three (3)
years. Waste application records for all other waste shall be maintained for five (5) years.
23. Dead animals will be disposed of in a manner that meets North Carolina regulations.

This plan will be implemented in the event that waste 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 posted in an
accessible location for all employees at the facility. The following are some action items
you should take.
1. Stop the release of wastes. Depending on the situation, this may or may not be
possible. Suggested response to problems are listed below:
A. Lagoon overflow -possible solutions are:
a. Add soil to berm to increase elevation of dam, any permanent alteration of the
dam should be approved by a qualified technical specialist.
b. Pump wastes to field at an acceptable rate.
C. Stop all additional flow to the lagoon, hold wastes in the house if possible.
d. Call a pumping contractor.
e. Make sure no surface water is entering lagoon.
B. Runoff from wastes application field -action include:
a. Immediately stop wastes application.
b. Create a temporary diversion or berm to contain the waste.
C. Incorporate waste to reduce further runoff.
d. Evaluate and eliminate the reason(s) that caused the runoff.
e. Evaluate the application rates for the fields where runoff occurred.
C. Leakage from the waste pipes and sprinkler -action includes:
a. Stop recycle (flushing system) pump.
b. Stop irrigation pump.
C. Close values to eliminate further discharge.
d. Repair all leaks prior to restarting pumps.
D. Leakage from flush system, houses, solids separators -action includes:
a. Stop recycle (flushing system) pump.
b. Stop irrigation pump.

3:37 PM
C. Make sure no siphon effect has been created.
d. Stop all flows in the house, flush systems, or solid separators.
e. Repair all leaks prior to restarting pumps.
E. Leakage from base or sidewall of lagoon. Often this is seepage as opposed to
flowing leaks -possible action:
a. Dig a small sump or ditch to catch all seepage, put in a submersible pump, and
pump back into lagoon.
b. If holes are caused by burrowing animals, trap or remove animals and fill holes
and compact with a clay type soil.
C. Have a professional evaluate the condition of the sidewalls and the lagoon
bottom as soon as possible.
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 what duration?
C. Any damage noted, such as employee injury, fish kills, or property damage?
d. Did the spill leave the property?
e. Does the spill have the potential to reach surface waters?
f Could a future rain event cause the spill to reach surface waters?
g. Are potable water wells in danger (either on or off of the property)?
h. How much reached surface waters?
3. Contact appropriate agencies.
a. During normal business hours, call your DWQ (Division of Water Quality)
regional office, at 910-433-3300, after hours, emergency number: 1-800-858-
0368. Your phone call should include: YOUR NAME , FACILITY

Mortality Management 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.
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.106-403). 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.
Complete incineration according to 02 NCAC 52C .0102.
A composting system approved and permitted by the NC Department of Agriculture & Con-
sumer Services Veterinary. Division (attach copy of permit). If compost is distributed off -farm,
additional requirements must be met and a permit is required from NC DEQ.
In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture & Consumer Services (G.S. 106-549.70).
Any method which, in the professional opinion of the State Veterinarian, wouldmake 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 AND MA[NTENANCE PLAN
______________________________
This lagoon is cesignec for waste treatment (permarent srorage) ard
180 days of temporar/ storage. The �ime required for mhe planned
fluid love! (permanent and temporary storage) to be reachcd may var-y
due to site conditions, weather, flushing operations, ana the amount
of fresh water added to tne system.
The deszaned temperary storage consists Of 18C days storage for:
(1) waste from animals and (2) excess rainfall after evaporation. Also
inc!uded is storage for the 25 year - 2u hour storm fcr the locanior.
�he volume of waste generateo from a g%ven numner of animals will be
iairly constant throughout the year anu from year to year, but excess
rainfall will vary from year to year. The 25 year rainfall will nct
be a factor to consider in an annual pumping cycle` but this storage
vol'/me 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 oumping should begin. An elevation Tait be established
to stop pumping to maintain lagoon treatment depth.
Pumping can He started or stopped at any time between these twz
elevations for operating convenience as site conditions permit, such as
weather, soils, crop, anu equipment in order to apply waste without
runoff or leaching.
Land applioation 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 damage to crops.
The following items are to be carried out:
1. It is strongly recomm-nded that the treatment lagoon be pre
charged to 1/2 its capacity to prevent excessive odors during
start-uo. Pre -charging reduces the concentration of the initial
waste entering the lagoon thereby reducing odors. Solids ghould be
covered with effluent at all times. When precharging is complete,
flush buildings with recycled lagoon liquid. Fres" watsr should not
be usea for flushiig after initial filling.
2. The attached waste utilization plan shall be followed. This
plan reccmmends sampling and testing of waste (see attachment)
before land applicaVion.
3. Begin temporary storage pump -out of the lagoon when fluid level
reaches the elevation 49.3 asmarked by permanent marver. Stop pu-p-
out when the fluid level reachAs elevation 47.0 . This temporary
storage, less 25 yr- 24 hr storm/ contains 3703C cubic feet or
276984 gallons.
SHEET 2 OF 2
4. The recommended maximv^' amouat to apply per irrigation is
one (1) inch and the recommender maximum application rate is ()'3
inch per hour. Refer to the waste utilization olan !or further details.
5. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be Tertilized as needed

OPERATION AND MAINTENANCE PLAN
SHEET 1 OF 2
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 yr - 24 hr storm for the location and a
heavy rain factor. 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 heavy rain
factor and 25 yr- rainfall will not be a factor to consider in an annual
pumping cycle, but this storage volume must always be available.
The waste produced by the animals shall be utilized in accordance with
an approved waste utilization plan. Highly visible markers shall be
installed to mark the upper and lower elevations of the temporary
storage (pumping volume). Pumping shall be done as necessary to
maintain the liquid level between these markers.
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.
L..and 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 damage to crops.
The following items are to be carried out:
1. Before wastes are introduced, the waste treatment lagoon shall be
charged to 1/2 its treatment volume 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 49.60 as marked by permanent marker. Stop pump -
out when the fluid level reaches elevation 47.00 This temporary
storage less 25 yr and heavy rain contains 69176 cubic feet or
517436 gallons.

4. The recommended maximum amount to apply per irrigation and
recommended maximum application rate is shown in the waste utilization
plan. 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 a vigorous stand.
h. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. Repair areas of the embankment that settle below the design settled
height or areas where cracking, sloughing, or "jug" holes develop.
8. Repair waste inlet pipes that develop cracks or separate at the
,joints.
9. Remove undesirable vegetative growth and floating or lodged debris.
10. All surface runoff is to be diverted from the lagoon to stable
outlets when not included as part of the design temporary storage.
11. After five years the waste treatment lagoon shall be checked for
sludge accumulation annually. If sludge has encroached into the
treatment volume, the sludge will be removed and applied at agronomic
rates based on analysis of the sludge. Treatment volume must have
a minimum of 4 feet of depth free of sludge at all times.
12. In December 1992, the Environmental. Management Commission (EMC)
in North Carolina revised water quality regulations that address
animal operations. These rules became effective on February 1,
1993 (15A NCAC 2H .0200). This animal operation shall be operated
within the requirements of these rules and regulations.
13. Pipes that are used for recycling effluent to use as flush water
and irrigation intakes must be placed 18 inches below the surface and
as far from the inlet discharge pipes as possible in order to provide
a cleaner effluent for flushing and to reduce odors when irrigating on
land. When these pipes are placed through the embankment, they should
be installed no more than two feet below top of embankment and not in
the highest section of fill. The pipe trench shall be compacted with
clayey material or other material as approved by an engineer.
