1.0 PROJECT DESCRIPTION
Smithfield Hog Production is proposing to cover one anaerobic lagoon to create one covered digester
and biogas collection system on this 100-acre farm. The farm is in northeast Northampton County
approximately 1.5 miles northwest of Seaboard, North Carolina. The site will continue to raise finisher
pigs and will add the biogas collection portion to the existing system. The proposed project consists of
one soil improved (clay) lined, synthetic covered lagoon; two existing lagoons utilized as waste storage
ponds. Finishing animal manure will be collected into the covered lagoon by a combination of gravity
discharge where possible and lift stations where necessary. Each covered lagoon will include; a mixing
station, a biogas conditioning skid, and buried biogas pipeline to transport the biogas to the cleaning
station. The purpose of this narrative is to describe the covered lagoon RNG capture system that will be
modified at this site in addition to the existing permitted anaerobic lagoons and spray field.
2.0 SITE DESCRIPTION
The Farm 40 is a Smithfield Hog Production/Murphy Farms, Inc. company owned finisher. It is a large,
combined permit for 9,832 head wean to finish. The site currently consists of multiple finishing barns.
The farm has a two -stage anaerobic waste lagoon Systems. The farm has been in some form of
operation since 1991 with the majority of the operations built in the early 1990's.
3.0 PLANNED SITE CONSTRUCTION
1. The main construction portion for this site will be covering an existing lagoon. The lagoon will
receive waste from barns via gravity discharge to receive waste. Other construction activities will be
recycle water pump relocation to allow recycle water to be pumped from open top waste storage
ponds to the barns that are flowing into the covered lagoons, water return lines to remove effluent
water from the covered lagoons and store in the waste storage ponds and gas collection pipe
network throughout the property.
There will be two lift station at each farm (as Applicable), a concrete tank buried sufficiently deep to
allow discharge from the header pipes at the Farms. The lift stations will have one or two GEA 4"
Manure Pumps. This lift stations will have the top of the lift station above the lowest buildings
finished floor elevation. If the pumps do not control the water, the water would then seek level
inside of the buildings using the pits as storage. No water would go over the top of the lift station
before it was visible in the barns to the employees. Wastewater collected in the lift station is
pumped through a 6"/8" DR 17 high density polyethylene (HDPE) force main into the digester.

3. The covered lagoon is an existing earthen basin constructed from native soils and lined with
compacted clay. There will be 1 covered lagoon in total on the site. The cover will be constructed
from 80 mil HDPE and will be secured into an anchor trench at the top of the berm for each site.
The cover will have weighted pipes on top for ballast and to channel rainwater into manageable
areas. The rainwater will be pumped off the cover into the adjoining fields.
4. All the waste from the buildings will be discharged under the covered lagoon. A modified baffle
system is proposed for the system. A mixing pump will be installed at the covered lagoon. The
pump will pull water from under the cover and discharge it back into the covered lagoon. If the
pump does not turn on due to a failure, no wastewater can leave the system. The mixing system
cycle time will be optimized to ensure distribution of feed stock to the anaerobic bacteria.
5. The liquid level of the covered lagoon will be maintained at an operating level of 21"-27" with 12" of
structural freeboard by a 12" outlet pipe into a level control pump station. Water under the cover
will use gravity to flow out of the 12" pipe into the pump station. From the pump station the liquid
will flow by gravity through a 12" overflow pipe set at 24" and/or be pumped to the existing lagoon
storage system.
6. The required waste treatment is now under one covered lagoon so the remaining existing lagoons
will now run as waste storage ponds. The waste storage ponds will be used for secondary storage
volume. In the event the covered lagoon digesters fail or other unforeseen catastrophic events
occur, the waste storage ponds can revert to their originally permitted lagoon status. The CAWMP
will manage the land application of nutrients stored in the waste storage pond.
7. Biogas will be collected under the 80 mil HDPE cover. To remove the gas there will be a perforated
pipe at the top of the berm under the cover to provide a pathway for the gas. The pipe will be
buried under the anchor trench and come out on the outside of the covered lagoon digester dike.
The gas will be piped to the skid mounted biogas conditioning pad. The on -farm biogas conditioning
pad removes moisture from raw biogas. This clean condensate will be pumped into the adjoining
field or returned to the lagoon. The dry biogas will now enter the on farm pipeline to be carried to
the centralized gas cleaning station.

II. Introduction
The Waste -to -Energy project uses anaerobic digestion of hog waste (aka waste) to produce biogas
(consisting of approximately 65% methane, which is the primary constituent of natural gas) which is
collected, conditioned, and ultimately injected into the utility's natural gas pipeline. The farm site includes
gravity collection piping from the barns, an Anaerobic Digester (Digester), a Mixing Pump Station, a Biogas
Conditioning System to remove moisture, an Emergency Vent, and a biogas transfer pipe leading to the
Gas Upgrading System (GUS).
The Digester at the farm site includes an HDPE membrane cover to capture the biogas generated by the
anaerobic digestion process. The Digester is partially mixed by pumping and provides sufficient detention
time to effectively reduce the volatile suspended solids in the waste by digestion. The reduction of
volatile solids through microbial processes produces an energy -rich biogas, which is a valuable commodity.
The Digester operates differently at certain temperature ranges. The Digester as installed is an ambient
temperature Digester. There are no heating devices to control the temperature in the Digester, the depth
of the Digester and the ground temperature will buffer the swing in temperature due to the outside
climate. The expected gas production from the Digester will fluctuate with the seasons, methane
production will almost stop when the temperature in the Digester drops below 50 degrees (F) and will
peak in the summer months.
There are two (2) types of solids found in hog waste: organic and inorganic.
1. The organic solids will break down and decompose by biochemical reduction. The bacteria that are
grown and maintained in the system is harmless anaerobic and aerobic bacteria. Bound oxygen can
be found in nitrates, a compound that results from the aeration process. These same bacteria are
provided by nature and are found in streams, lakes, and in the soil to destroy dead plants and animals.
The difference is that a Waste -to -Energy System treatment process has provided an ideal environment
for a concentration of these bacteria to feed and grow; thus, the biological action is greatly
accelerated. The hog waste is the food for the bacteria in the system. The Digester contains certain
populations of bacteria that do not require the presence of oxygen.
2. The inorganic solids are "non -treatable," but they are normally present in such small quantities that
they are considered insignificant in the treatment process.
The loading rate of the Digester will not be strictly controlled. There is no change in the flush routine of
the current farm operations; a continuous and consistent stream of hog waste is the best method
available of loading the Digester. Total solids account for approximately 1% of the influent content,
varying with the stocking density and the age of the animals. The Digester is constructed to be air -tight;
the lack of oxygen will facilitate the growth of methanogenic bacteria.
Ill. Operational Components of the Waste -to -Energy System
Below are listed the major component operations.
1) Gravity Collection Pipe
The gravity collection pipe receives the flushed waste from the hog barns and directs that waste to a
lift station or directly into the Digester via gravity. During normal operation, the pipe should be free
flowing, with no clogs, in order to transport the waste. The gravity collection pipe includes a series of
cleanouts that provide access to the gravity collection pipe for removal of a clog or blockage.
Waste -to -Energy System 0&M Manual Original: 11/1/21
Page 4 of 11

2) Lift Station, where applicable
The Lift Station receives waste from the gravity collection pipe and pumps that waste to the Digester
via buried forced main. The waste enters the Digester at the opposite end of the Digester from the
Level Control System (so "new" waste must flow through the curtain baffle system of the Digester,
resulting in effective treatment of the waste).
During normal operation, the Lift Station will run based on the liquid level in the pump tank, which is
triggered by floats. The Lift Station will be inspected per procedure by the farm manager, or their
designee, to ensure the pumps are operating to indicate proper flushing. The Lift Station is equipped
with alarms.
Reference the Smithfield Hog Production Lift Station Manual for proper operation and maintenance of
the lift station.
NOTE: Some farms do not have Lift Stations, rather than using a Lift Station, the waste flows from the
hog barns to the Mixing Pump Station or flows directly into the Digester via gravity.
3) Anaerobic Digester (aka Digester)
The Digester receives the wastes from the hog barns. The complex organic wastes are broken down
to simpler compounds by the anaerobic digestion process. As a part of the anaerobic process,
biogases (including methane, carbon dioxide, and hydrogen sulfide) are produced. These gases are
captured by an impermeable cover and then directed to the Biogas Conditioning System. The gases
are collected in perforated piping underneath the cover, which are connected to a main pipe that
connects to the conditioning system. The waste is held for approximately 45 days to allow the
biological process to complete. The sludge that settles at the bottom of the Digester will be
periodically removed, based on the annual sludge survey.
During normal operation, the Digester cover will likely be "inflated" like a balloon due to the biogas
that's trapped beneath. The cover should be free of excessive accumulation of rainwater (no more
than 10% of the top of the Digester should be covered by rainwater) and should not show signs of
any damage or leaks. The presence of an unusual odor (rotten eggs), or wastewater on the cover
may indicate that there is a leak. If such odors or wastewater are observed, the Environmental
Emergency Contact Plan should be activated immediately. Temporary repairs should be followed
with a permanent repair as soon as possible. Documented tracking of the repair process is required.
(i.e., a work order).
4) Mixing Pump Station
The Mixing Pump Station slowly mixes the waste that has been collected in the Digester, which
provides for more efficient methane production than would be achievable without any mixing. During
normal operation, the pumps will run at the same time for several hours per day to mix the waste in
the Digester. The Mixing Pump Station is equipped with an audible and visual alarm.
5) Level Control Station, where applicable
The Level Control Station receives treated waste from the Digester and conveys that waste to the
Effluent Storage Pond. The gravity outlet of the Digester leads to the inlet of the Level Control
Waste -to -Energy System O&M Manual Original: 11/1/21
Page 5 of 11

Station, and the invert is set at the freeboard of the Digester so that the Digester maintains a
constant level. The staff gauge for indicating the liquid level of Digester is located in the wet well of
the Level Control Station. The liquid level is visually inspected at least daily by farm personnel for
unexplained changes. Any unexplained changes in liquid level of two or more inches, should initiate
the Environmental Emergency Contact Plan. The Level Control Station is equipped with an audible
and visual alarm.
6) Effluent Storage Pond
The treated waste from the Digester flows from the Digester outlet pipe to the Effluent Storage Pond.
The Effluent Storage Pond is used to store the treated effluent after anaerobic digestion. However, as
this is a critical part of the integrated system, any abnormal operation of the Effluent Storage Pond
observed by farm or LNM personnel, such as seepage and/or unexplained liquid level changes of two
or more inches, should be documented and immediate corrective action taken.
7) Biogas Conditioning System
The Biogas Conditioning System receives biogas from the Digester and removes moisture from the
biogas by means of compression and heat exchangers.
This system will be managed by a contractor, but the information is included in this O&M manual for
reference.
The biogas from the Digester is commonly at 100% relative humidity; the biogas is purported to be
near 6% relative humidity after going through the Biogas Conditioning System. The biogas is moved
through the biogas transfer pipe to the Gas Upgrading System (GUS)
During normal operation, the conditioning system should run without any need for input from the
contractor. The discharge pressure and flow rate can be manipulated by the contractor through
adjustment of the pressure regulator on the bypass line and through adjustment of the variable
frequency drive. As the conditioning system approaches this setpoint, it will automatically reduce
compressor speed to seek a flowrate that matches the biogas production. If the vacuum pressure
exceeds the setpoint, the conditioning system will shut down and trigger an alarm to the contractor
via telemetry system.
8) Emergency Vent
In times of need, such as failure of the biogas conveyance pipeline, the Emergency Vent is operated by
trained personnel to consume excess accumulated biogas from the Digester. The Emergency Vent is
not an automated system, and the trained operator must articulate the biogas piping control valving
to direct biogas from the Digester to the Emergency Vent for release.
9) Transfer Pump, if applicable
The Transfer Pump transfers accumulated effluent among available Effluent Storage Ponds to optimize
storage. The Transfer Pumps are operated through use of a local disconnect. Under normal
circumstances, the Transfer Pump will only be used as needed.
Waste -to -Energy System O&M Manual Original: 11/1/21
Page 6 of 11

10) Rainwater Removal Pump
A designated pump is located at each Digester site to remove accumulated rainwater from the cover
of the Digester. In order for the Digester dike to not be jeopardized, the pump outlet should reach
beyond the toe of the Digester dike. Rainwater should be pumped on to a grassy area, if possible.
IV. General Maintenance
Maintenance should be performed to evaluate the performance of the Waste -to -Energy System.
A well -operated, properly adjusted, system will exhibit the following visible signs of proper maintenance:
• All pipes should be intact and watertight.
• The pumps appear to be operating properly (nearly silent with little to no vibrations)
• The Digester cover should be free of excessive accumulation of rainwater
• The Digester cover should be free of any tears, punctures, or failures
• There should be no unusual odors (rotten eggs) coming from the Digester or Emergency Vents.
• The Effluent Storage Pond should be structurally sound, free of floating debris, and within permitted
liquid level
For optimum system operation and maximum treatment efficiency, daily visual inspection of alarms, by
production personnel, is necessary. In addition to the daily visual inspection, all mechanical equipment
(Mixing Station pumps, Level Control pumps, Lift Station pumps, and Transfer Pumps) should be cleaned
and lubricated as needed. At least quarterly mechanical equipment valves need to be performance
tested. The maintenance for the mechanical equipment will be managed by the Regional Maintenance
Department.
V. Safety
Reference Lagoon Safety Policy (SIPS 8.1)
VI. Spill Prevention and Control
Audible and visible alarms are present at the following controls stations: Mixing Pump Station, Lift
Station, and Level Control Station. The alarms are tested for proper operation per design periodically
by production personnel or the Land & Nutrient Management Department.
The Environmental Emergency Contact Plan provides spill control instructions and contact
information.

Appendix A — Responsibilities
Farm Production Personnel
1. Organic Loading
The normal operations of the farm site for the Digester includes animal waste, feed spilled in pit by animals,
and water. The control of fresh water into the pit is important. Water leaks in the barn or malfunctioning
nipples need to be repaired in a timely manner. Ensure there are not blockages in the flush lines that impede
the flow of fresh waste to the Digester.
2. Hydraulic Loading
During times of cleaning and disinfecting a barn, solutions with chlorinated compounds (bleach) or quaternary
ammonium inhibit anaerobic digestion. Also, the common use of lime in the disinfecting process causes a
disruption in alkalinity in the Digester that harm methane forming bacteria.
3. Digester Level Control
A liquid level gauge will be located in the wet well at the Level Control Station. Daily the farm manager, or
their designee will need to record liquid level of the Digester. If there is an unexplained level in the Digester of
two or more inches, the Environmental Emergency Contact Plan will be activated.
4. Lift Station Maintenance, if applicable
Periodic cleaning of the Lift Station is necessary to remove debris and maintain the free flow of wastewater to
the Digester. The emergency alarm is tested per procedures. Refer to the Smithfield Hog Production Lift
Station Manual.
5. Daily Inspections
The farm manager or their designee will document daily the inspection of the following Waste -to -Energy
components:
• Gravity collection pipe cleanouts
• Mixing Pump Station alarm
• Digester liquid level
• Level Control Station alarm
• Lift Station
• Waste Storage Pond liquid level
6. Emergency Response
The farm manager, or their designee will immediately activate the Environmental Emergency Contact Plan
posted on site, in the event of emergency alarm activation, unexplained liquid level change in Digester and/or
Effluent Storage Pond or noticeable difference in normal operation of the Waste -to -Energy system
components located on the farm site.

11. Land & Nutrient Management Personnel (LNM)
1. Digester Cover Waste Removal
Any liquid on the Digester cover should be inspected to make sure it is clean and clear. If wastewater is
detected on the cover, pump all water present on the cover back into the Level Control Station wet well or the
Lift Station, and activate the Environmental Emergency Contact Plan.
2. Digester Cover Rainwater Removal
Removal of rainwater from the Digester cover is necessary to help maintain cover integrity, and to help with
the digestion process. (Reference Smithfield Hog Production Policy/Procedure #MB 031). Rainwater will be
removed by a pump designated for the Digester. In order for the Digester dike to not be jeopardized, the
pump outlet should reach beyond the Digester dike. Rainwater should be pumped on to a grassy area, if
possible.
3. Weekly Inspections
Document on the Weekly LNM Inspection:
• Pumps/pipes into and out of Digester and waste storge pond
• Digester cover integrity
• Digester and waste storage pond dike integrity
• Digester cover inflation
• Rainwater accumulation on Digester cover
4. Effluent Storage Pond
• Record the liquid level weekly
5. Transfer Pump
• Operate the Transfer Pump as needed
6. General Maintenance
• Keep area around Digester mowed. Mowing activity must be regimented around the Digester cover to
guard against propelling debris towards the cover.
• Check the Digester cover after a rain event, and pump off excess rainwater, if necessary.
• Monitor liquid level in Digester, per design. Use the staff gauge located in Level Control Station wet well
to assess levels.
• Inspect Level Control Station for proper operation, visually check for blockages.
• Inspect waste outlet pipes from the Digester to the Effluent Storage Pond at least weekly for leaks.
• Check Mixing Pump Station and Level Control Station alarms at least weekly for properly operation as
designed.
7. Emergency Response
• Activate the Environmental Emergency Contact Plan if there is an unexplained change in cover inflation
level.
• Maintain emergency contacts for the Waste -to -Energy System components located on the farm site.

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 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 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 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.
1 of 8

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.

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, 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 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.

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 pounds of plant available nitrogen per year 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 0 pounds of plant
available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 0 acreas of land. If you apply the sludge
to corn at a rate of 125 pounds per acre, you will need 0 acres of land. Please note that these
are only estimates of the PAN produced and the 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 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
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.

Owner/Manager Agreement:
Farm 40A & 40B Facility 66-5
Smithfield Hog Production
I/we understand and will follow and implement the specifications and the operation and
maintenance procedures established in the approved animal waste nutrient management
plan for the farm named above. I/we know that any expansion to the existing design capacity
of the waste treatment and/or storage system, or construction of new facilities, will require a
new nutrient management plan and a new certification to be submitted to DWQ before the new
animals are stocked.
I/we understand that I must own or have access to equipment, primarily irrigation equipment,
to land apply the animal waste described in this nutrient management plan. This equipment
must be available at the appropriate pumping time such that no discharge occurs from the lagoon
in the event of a 25 year 24 hour storm. I also certify that the waste will be applied on the land
according to this plan at the appropriate times and at rates which produce no runoff.
This plan will be filed on site at the farm office and at the office of the local Soil and Water
Conservation District and will be available for review by NCDWQ upon request.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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.
Z There must be documentation in the design folder that the producer either owns or has an
agreement for use of adequate land on which to properly apply the waste. If the producer
does not own adequate land to properly dispose of the waste, he/she shall provide
evidence of an agreement with a landowner, who is within a reasonable proximity,
allowing him/her the use of the land for waste application. It is the responsibility of the
owner of the waste production facility to secure an update of the Nutrient Utilization Plan
when there is a change in the operation, increase in the number of animals, method of
application, recieving crop type, or available land.
3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic
crop yields based upon soil type, available moisture, historical data, climatic conditions,
and level of management, unless there are regulations that restrict the rate of applications
for other nutrients.
q Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land eroding at more than 5 tons per acre per year but less than 10 tons
per acre per year provided grass filter strips are installed where runoff leaves the field
(See USDA, MRCS Field Office Technical Guide Standard 393 - Filter Strips).
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 land application field.
6 When animal waste is to be applied on acres subject to flooding, waste will be soil
incorporated on conventionally tilled cropland. When waste is applied to conservation tilled
crops or grassland, the waste may be broadcast provided the application does not occur
during a season prone to flooding (See "Weather and Climate in North Carolina" for
guidance).
7 Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that runoff
does not occur offsite or to surface waters and in a method which does not cause drift
from the site during application. No ponding should occur in order to control odor and
flies.
8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the
1 of 3

NUTRIENT UTILIZATION PLAN
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 damage
from animal waste should also be considered.
1p Nutrients from waste shall not be applied in fall or winter for spring planted crops on soils
with a high potential for leaching. Waste/nutrient loading rates on these soils should be
held to a minimum and a suitable winter cover crop planted to take up released nutrients.
Waste shall not be applied more than 30 days prior to planting of the crop or forages
breaking dormancy.
Any new swine facility sited on or after October 1, 1995 shall comply with the following:
11 The outer perimeter of the land area onto which waste is applied from a lagoon that is a
component of a swine farm shall be at least 50 feet from any residential property
boundary and canal_ Animal waste, other than swine waste from facilities sited on or after
October 1, 1995, shall not be applied closer than 25 feet to perennial waters.
Animal waste shall not be applied closer than 100 feet to wells.
12
Animal waste shall not be applied closer than 200 feet of dwellings other than those
13 owned by the landowner.
Waste shall be applied in a manner not to reach other property and public right-of-ways.
14
Animal waste shall not be discharged into surface waters, drainageways, or wetlands by
discharge or by over -spraying. Animal waste may be applied to prior converted cropland
15 provided the fields have been approved as a land application site by a "technical
specialist'. Animal waste shall not be applied on grassed waterways that discharge
directly into water courses, and on other grassed waterways, waste shall be applied at
agronomic rates in a manner that causes no runoff or drift from the site.
16
Domestic and industrial waste from washdown facilities, showers, toilets, sinks, etc., shall
not be discharged into the animal waste management system.

(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.
Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular
19 basis to prevent breakdowns, leaks and spills. A regular maintenance checklist should be
kept on site.
Animal waste can be used in a rotation that includes vegetables and other crops for direct
20 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.
Highly visible markers shall be installed to mark the top and bottom elevations of the
21 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.
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
22 nutrient, unless other restrictions require waste to be applied based on other nutrients,
resulting in a lower application rate than a nitrogen based rate. Zinc and copper levels in
the soil shall be monitored and alternative crop sites shall be used when these metals
approach excessive levels. pH shall be adjusted and maintained for optimum crop
production. Soil and waste analysis records shall be kept for a minimum of five years.
Poultry dry waste application records shall be maintained for a minimum of three years.
Waste application records for all other waste shall be maintained for a minimum of five
years.
23
Dead animals will be disposed of in a manner that meets North Carolina regulations.
