Subject: Hog Pack #1
Facility # NCA231152
State Digester General Permit
Dear Ms. Lawson,
AFO Permit Application
Roeslein & Associates, on behalf of the farm owner, hereby submits the following application to NCDEQ Division of Water
Resources for review of the State Digester General Permit application package for Hog Pack #1. The subject project is located in
Duplin County, North Carolina.
The digester constructed on this property will meet setback parameters as required per the Swine Farm Siting Act. The digester
is beyond 1500 ft from any occupied residence, 2500 ft. from any public building, beyond 500 ft. from property lines, and beyond
500 ft. from any public water source.
Digester influent and effluent will be sampled from wet wells on site per the Sampling Protocol and Schedule document in this
package. The digester water level will be monitored by a level gauge installed in the digester -lagoon transfer wet well.
The digester will generate approximately 40,500 SCF of gas per day. This biogas is intended to be used within 6 months of
beginning to collect gas. A portable flare unit will be connected to an emergency vent at the digester if needed. Spare parts for
the gas upgrading systems will be kept on the shelf so readily available as needed. The digester cover will be provided with
emergency vents which are strategically located away from barns/public but still provide access for operators. Safety procedures
for venting covers are called out in the 0&M document. See Narrative for more information.
Per the Air Permit Applicability Request for Register 1 cluster of farms, submitted to NCDEQ Division of Air Quality, the annual
emission rates from the gas upgrading system associated with this farm are below the thresholds indicated in 15A NCAC
02Q.0102(d) and therefore does not require an air permit.
To facilitate your review of the enclosed documentation, the following is an itemized breakdown:
1. One (1) original "State Digester General Permit Application" application form.
2. One (1) copy of the engineering calculations.
3. One (1) copy of a detailed narrative of the Swine Digester Animal Waste Management System.
4. One (1) copy of Digester 0&M Procedures, Sampling Protocol, and Emergency Action Plan.
5. One (1) copy of the FEMA FIRM map labeled with the "proposed Digester Site".
6. One (1) copy of OIC Form.
7. One (1) copy of revised WUP.
8. One (1) copy of the permit form Section 3.6 components.
9. One (1) full-size set of the engineering plans, as well as one (1) 11x17" set.

Note: Since Lagoon 27507A was built before 1996, rainfall from all sources is from only one rain event
To avoid over -filling Lagoon 27507A in the event of a historic rainfall, it is the recommendation of Roeslein that pumping begins at 620,904 cuft
This would reduce the pre -rainfall height of Lagoon 27507A from 10.03 ft. to 9.41 ft. (69.41 ft. elevation)
This modification will increase the pre -rainfall freeboard from 23.6 in. to 31.1 in. to accommodate the additional rainfall from Lagoon 27507B
This modification will ensure the 12 in. of freeboard required (per the NRCS Anaerobic Digester standard) in Lagoon 27507A after the historic rainfall event

Farm will utilize existing barns with slotted floors over flushing pits to collect manure. The farm
operators use pull plug system and recycle water for flushing to manage the animal manure. As part of
this current project, a new anaerobic lagoon digester will be installed, and the animal manure will be
redirected to the new digester. After treatment in the in anaerobic digester, the effluent will flow into
the existing lagoon. There is no change to the existing farm operations, nor the volume of wastes
generated. The effluent water will be recycled back to the barn for pit recharge or irrigated in
accordance with the existing Waste Utilization Plan (WUP).
Upon flushing, the wastewater from the barns will be directed into a properly designed lift station
through a 12-inch diameter gravity pipe header. There will be two pumps in the lift station wet well and
each pump is designed for 100% of the design flow.
The lift station pump at Hog Pack 1 Barns 1-3 will be 15 HP GEA pump, designed for a flow of 545
gallons/minute, through 6-inch diameter, HDPE SDR 17 force -main into the new anaerobic lagoon
digester.
Upon flushing Hog Pack 1 Barns 4-6, the wastewater will be directed through a 12-inch diameter gravity
pipe header directly to the digester.
The approximate dimensions of the new anaerobic lagoon digester are 330 feet by 170 feet with a total
volume of 477,936 cubic feet and a treatment capacity of 371,640 cubic feet at operating level.
Before the excavation, the project area is stripped approximately 6 inches of topsoil and will be
stockpiled. Embankment material will be free of sod, roots, and other objectionable material. The
maximum thickness of each compacted layer will be 6-inches and compacted to 95% of Standard Proctor
at -1 to +3 percent of optimum moisture content per ASTM D698. Each lift shall be tested for moisture
and density. The stockpiled topsoil will be spread on the outside bank.
After the construction the lagoon, and all required pipe penetrations, the inside walls of the lagoon will
be smooth rolled prior to the installation of the baseliner. The baseliner will be 60-mil thick HDPE
synthetic liner. After the liner is installed, it will be tested for leaks prior to filling the lagoon with
wastewater.
There will be an outlet structure with a transfer pump (level control) that keeps the water level inside
the digester at a constant level. The effluent will gravity flow through a 12-inch diameter digester outlet
pipe to the level control wet well and be transferred by pump into the existing lagoon through a 6-inch
diameter pipe.
The transfer pump will be 10 HP GEA pump, designed for a flow of 560 gallons/minute, through 6-inch
diameter, HDPE SDR 17 force -main to existing lagoon.
Water will be transferred back to the existing lagoon at Hog Pack 1 Barns 1-3 by gravity flow through a
12-inch diameter gravity pipe from existing lagoon at Hog Pack 1 Barns 4-6.

Definitions
Anerobic Digestion — The process of decomposing organic waste material through the use of bacteria in the
absence of oxygen to produce Biogas and Digestate.
Anerobic Digester- A sealed basin or tank designed contain the waste and capture the Biogas during
anerobic digestion.
Biogas- A product of Anerobic Digestion, produced by fermentation of organic materials. It typically has a
composition of mainly methane and carbon dioxide, with traces of nitrogen, oxygen, hydrogen sulfide, and
water.
Digestate — liquid/solid digester effluent.
Introduction
The Project uses anerobic digestion of swine waste to produce biogas. The biogas is captured, upgraded to
RNG, and combined with other swine site RNG before being ultimately injected into a utility's natural gas
pipeline.
The Project includes manure influent piping from the swine barns, an anerobic digester, biogas take -off
pipe going to the Micro Gas Cleaning System (µGCS), and digestate transfer system to open storage lagoon.
The barn waste stream contains two types of solids: organic and inorganic. A portion of the organic solids
are broken down (digested) to produce biogas. The digestion of organic solids occurs as a result of several
"types" of microbes, which exist in a symbiotic relationship. The naturally occurring microbes are one of
nature's ways of breaking down organic material. The digester provides an ideal environment for the
microbes to thrive. The inorganic solids either settle at the bottom of the digester or exit in the digestate
stream as a dissolved solids or suspended solids.
In addition to the information provided in the document, the operator should familiarize themselves with
the local, state, and federal laws that may apply to operation of this site.
Description of the Operational Components
Below are listed the major component operations.
Gravity Collection Pipe
The gravity collection pipe receives waste from the hog barns and directs that waste to either an
influent lift station or directly to the earthen lagoon digester. Typically, the diameter of the pipe is
8" (min) to 12 inches (max).
The gravity collection pipe includes several clean -outs that provide access to the gravity collection
pipe for removal of a clogs or blockage via use of a sewer snake or similar apparatus as needed.
Typically, there will be at least one cleanout every 200 feet. During normal operation, the pipe
should be free flowing, without obstructions, to transport waste to the lift pump station or directly
to the anaerobic digester.

Effective Date: 4/15/2024
The barn operator is responsible for sending barn waste to the gravity collection pipe. The
digester/biogas operator should check weekly, each hog barn waste outlet to ensure that there are
no overflows, clogs, etc.
Lift Pump Station (where necessary)
The lift pump station receives wastewater from the gravity collection pipe and pumps that
wastewater to the anaerobic digester via buried forced main. The waste enters the digester at the
opposite end of the digester outlet. During normal operation, the pump station will automatically
cycle on and off based on the liquid level in the wet well, which is triggered by float switches.
The pipe from each of the two pumps goes through a check valve (which only allows the liquid to
travel in one direction) and a plug valve (normally open, but can be closed when needed, such as
when servicing the upstream pump). The two pipes join via a tee, and the downstream pipe leads
to the inlet of the digester.
During normal operation, the pumps may run several times an hour to pump waste to the anaerobic
digester. Only one pump will run at any given time, normally, where the pumps will alternate
between cycles (Pump 1 will run while Pump 2 is off, and in the next cycle Pump 2 will run while
Pump 1 is off, and so on). It is not uncommon, for both pumps to operate during higher inlet flows.
The pumps can also be controlled manually, if desired, or in times of troubleshooting, etc. The
control panel next to the pump station includes toggle switches for each pump, which can be set to
either (1) Auto (for normal float -based operation), (2) Off, or (3) "Hand" (i.e., manual operation).
In the event of a pipe clog or lift pump failure, the waste will flow through the gravity "digester
bypass" pipe connecting the interior of the pump station to the existing lagoon at an elevation below
the top of the wet well, which will avoid overflow of the pump station.
Note: Some farms do not have Influent Pump Stations; rather than using a Lift Pump Station, the
waste flows from the barns directly to the anaerobic digesters.
Anaerobic Di eg ster
The anaerobic lagoon is constructed outside of the 100-year flood plain and any wetlands. The
treatment volume is designed utilizing a minimum volume of 50 cubic feet/head and with a
minimum HRT of 40 days. The construction approach will be a cut and fill balance. The excavated
material will be utilized to build the embankments. The berm fill material for the lagoon will be
placed in 6-inch-thick lifts to a minimum of 95% of standard proctor at -1% to +3% of optimum
moisture. Each lift fill be tested for moisture and density. The excavated material used for the
lagoon berm construction will be free of sod, roots, and other objectionable materials. The
minimum top width of the lagoon digester will be 15 feet with a minimum inside and outside slope
of 3:1.
After the construction of the embankment and after the installation of all pipes penetrating the
berms, the inside of the lagoon will be smooth rolled and a 60-mil thick HDPE liner will be installed
as the baseliner. Edges of the baseliner will be secured in an anchor trench at the top of the berm.

The anaerobic digester receives all raw waste 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 under an impermeable cover (80-mil thick HDPE liner) and then directed to the
biogas cleaning system. biogas blower or biogas dehydration system.
Biogas captured and stored under the cover supplies the biogas draw off piping. All berm
penetrations (gravity sewer, forced main, effluent to wet well, sludge removal piping must always
remain submerged to create a liquid seal to prevent biogas from escaping. Perforated piping
underneath the cover connects all sections of the lagoon to the draw off connection. The liquid
waste is digested for a minimum of 40 days.
The digester liquid effluent is either pumped or gravity fed to an existing storage lagoon. The
lagoon digester cover should be supported by the lagoon liquid when not inflated. Dropping the
lagoon liquid level too low may lead to an unsupported cover and possible cover stretching and
cover damage. Recommended operation level is 3-4 ft below top of berm to ensure adequate
digester biomethane production and ensure that the level does not exceed 2 ft below top of berm at
any time during operational deviances. The digester liquid level should be monitored daily.
Any settleable solids and microbes (i.e. "Sludge") build up slowly over months/years at the bottom
of the digester. These solids can be periodically removed by connecting portable pipes and pumps
to the sludge removal pipes in the digester and disposed of through permitted means on the farm or
by a contract sludge hauler.
There will be a total of eight 6-inch diameter sludge removal pipes installed near the bottom
elevation the lagoon and terminated near the top of the berm. Four installed on each side of the
central ballast pipe, staggered every other lateral. These pipes will be utilized for the periodic
removal from the lagoon.
Ballast piping on top of the cover control the cover inflation and direct rainwater to center rainwater
trenches to be pumped to natural water shed (if uncontaminated). The cover should be free of
excessive accumulation of rainwater and should not show signs of any damage or leaks.
The effluent of the anaerobic digester flows from the anaerobic digester through an outlet structure
and flows by gravity into the secondary lagoon. The outlet structure is equipped with a level gauge
with 1-foot markings. The outlet structure has an overflow weir to keep a constant freeboard of 2'
inside the lagoon digester. The effluent overflowing the weir will be directed to the secondary
lagoon by gravity.
During normal operation, the digester cover will inflate like a balloon from the biogas trapped
beneath, an inflation guide can be found in Appendix A. Proper inflation of the digesters is critical
to the reliable operation of the plant. A low level of inflation ensures that ingress of air doesn't
occur into the biogas which would contaminate the gas with nitrogen and oxygen. 100% full
inflation ensures that the covers are in an optimal state for 24-hour net heat gain by the digester and
prepared for normal atmospheric wind conditions. The pressure under the cover will typically range
from 0-0.3" w.c., a pressure of 0.4" w.c. can be dangerous.

Typical digester operation can be found in Appendix B.
Mixing Pump
A dry well will house a mixing pump which draws the water from the lagoon near the bottom
elevation and discharges the water near the influent side of the digester. This pump will be operated
on a regular interval. This pump is typically operated for approximately 4 hours a day, five days a
week.
Secondary Lagoon
The effluent of the anaerobic digester flows from the anaerobic digester outlet pipe to the secondary
lagoon. The secondary lagoon is used to store the treated effluent after anaerobic digestion until it
can be land applied.
There is an ammonia reduction unit installed on these secondary lagoons.
The farm operator is responsible for the operation and maintenance of the secondary lagoons.
Digestate liquid stored in the secondary lagoon is used for pit pre -charge and flush tank recharge.
The secondary lagoon is a critical part of the integrated system, the Digester/Biogas Operator
should note any abnormal operation of the storage basin, such as leaks or excessive liquid level,
and communicate such observations to the farm owner.
During normal operation, the storage basin will most often appear to be inactive. Waste will
periodically flow from the anaerobic digester outlet pipe into the storage basin via gravity or pump.
The outlet pipe from the anaerobic digester into the storage lagoon must remain submerged in the
digester to provide a liquid seal and prevent biogas from escaping from beneath the digester cover.
As such, it is not uncommon for the pipe to turn down and follow the direction of the inner slope
of the lagoon to ensure submergence during times when the lagoon liquid level may be low due to
normal pumping and irrigation activities.
Transfer Pump
The transfer pump transfers accumulated effluent among available secondary lagoons as the farm
owner desires to optimize effluent storage. The transfer pumps are manually operated through the
local disconnect. Under normal circumstances, the transfer pump will only be used periodically by
the farm owner. Typically, the transfer pump is used to draw down the digester liquid level in the
fall to make room in the digester to store lagoon liquid during the colder winter months.
Rainwater Cover Pump
Two rainwater cover pumps are installed on end of the digester to remove accumulated rainwater
from the digester cover. There will be a 3-inch suction line to each of these stormwater removal
pumps. Erosion control measures, such as rip rap will be placed at the discharge point.
Oxygen Injection System
An oxygen injection system will be installed to limit the amount of hydrogen sulfide in the biogas.
The oxygen injection system consists of an oxygen generation unit which produces 95% purity
oxygen from air, and it will be injected under the cover at two locations. Calibrated Oxygen

monitoring instrument continuously monitors the concentration of oxygen in the head space under
the cover. The maximum allowable oxygen concentration in the biogas will be 0.5%.
Description of Anticipated Maintenance
The system is designed to require as little maintenance as possible once it has been started up and is in
operation. Sample tests should be performed periodically and to permitting requirements, to allow
evaluation of the composition of the wastewater. System components should be visually inspected regularly
and as recommended by the equipment manufacturer. If the system is well operated, it will display the
following signs of being maintained properly:
• All pipes should be intact and watertight.
• The pumps should operate with little to no vibration and without excessive noise.
• The anaerobic digester should be free of excessive accumulation of rainwater on the cover. The
accumulated rainwater will be pumped off the cover via the Rainwater Pumps. The rainwater must
be tested to determine the discharge location for the pumps. If contaminated the rainwater must be
discharged back into the digester, otherwise it may be discharged safely on nearby vegetated areas.
• The anaerobic digester cover should be free of any tears, punctures, or failures.
• There should be no strong odors coming from the digester.
• The secondary lagoon should be clean and free of floating debris. The liquid should be clean an
clear.
Routine System Maintenance Instructions
For optimum operation and maximum efficiency maintenance should be performed daily.
mechanical equipment should be cleaned weekly and lubricated as required. Equipment cleaning
and lubrication should be done as specified in the O&M manuals provided by each equipment's
manufacturer.
Periodically, the sludge accumulated at the bottom of the digester will need to be removed, this will
be done by following the existing Waste Utilization Plan (WUP). The sludge may be removed
through the use of the sludge removal pipes utilizing a temporary pump. All application of the
removed sludge should be done in accordance with the farms approved WUP & Nutrient
Management Plan.
Typically, a portion of sludge will be removed from the digester every other year. Sludge
accumulation can be monitored by the site's operator through the use of inspections ports installed
on the top of the digester cover and should be assessed annually. When assessing the sludge
accumulation, the operator should aim to have as much biogas removed as possible prior to opening
the inspection port to limit release of biogas into the atmosphere. Due to biogas production
declining in cold weather, it is recommended to take sludge measurements during winter. To get a
measurement of the sludge depth, the site operator will use the inspection ports and insert a pipe or
gauge with graduated markings will be used to assess the depth of the sludge in the digester. When
inserting the pipe or gauge caution should be used to avoid applying excessive pressure or even
puncturing the liner of the digester. After sludge removal has been concluded, the operator should
reconnect all fittings from the sludge removal pipes and piping as it was prior to the sludge removal.

Troubleshooting
Refer to equipment O&M manuals as necessary, summarized below:
Emergency Protocols, Repair, and Replacement
The O&M Manuals provided by the equipment manufacturers should be kept onsite in a centralized
location, known to all who work around the equipment. The O&M manuals should provide
instructions for possible field repairs or how to secure a piece of equipment until qualified repair
personnel are able to arrive.
Biogas Hazards
Biogas and oxygen in air can potentially form a flammable mixture.
Methane (CH4) is an odorless, flammable gas. CH4 is lighter than air and tends to rise and dissipate
quickly outdoors.
In addition to being primarily comprised of methane (55 — 60%), biogas is also comprised of carbon
dioxide (35 — 40%), and trace amounts of hydrogen sulfide (H2S), nitrogen (< 2%), oxygen (< 1%),
and water vapor (<8%) which are hazardous.
Hydrogen Sulfide (H2S) has a distinct "rotten egg" odor at low concentrations. However, at higher
concentrations, it overwhelms the sense of smell and cannot be detected. At concentrations > 1000
ppm, it can cause immediate unconsciousness and death through respiratory paralysis. Hydrogen
Sulfide compositions in the biogas feed supply can be at 1500 to 2500 ppm/vol.
Carbon Dioxide (CO2) is a colorless, odorless, tasteless, non -irritating, non -toxic gas. However,
it can act as a simple asphyxiant by displacing oxygen present in air to levels below that required
to support life. In environments with low concentrations of oxygen, confusion and reduced mental
capacities can lead to poor judgement and increase the risk of safety events.
Nitrogen (N2) gas is a colorless, odorless, tasteless, non -irritating, non -toxic, inert gas. However,
it can act as a simple asphyxiant by displacing oxygen present in air to levels below that required
to support life. In environments with low concentrations of oxygen, confusion and reduced mental
capacities can lead to poor judgement and increase the risk of safety events.
Equipment Supplies
All equipment used around the digesters should be qualified to be used in Class Div2 areas.
Proper Protective Equipment (PPE)
All personel working around anerobic digesters should refer to local HSE officer for job specific
PPE requirements and need. At a minimum, the following PPE should be used whenever in the
vicinity of biogas.
0 4-gas personal monitor should be worn when in the vicinity of biogas

• Refer to local HSE officer for job specific PPE requirements and needs.
8. Procedure
No.
Procedural Step Description
Transfer Pump Operation
8.0.1
Transfer pumps transfer water from the covered lagoon digester to evaporative lagoons
to maintain the desired liquid level in the digester.
Lagoon digesters high level is limited to two (2) feet below top of berm (or freeboard).
Lagoon digester low pump level is limited to one (1) foot above the sewer inlet pipe
exit to maintain gas seal. All pipe -berm penetrations must remain sealed with liquid to
avoid allowing biogas escaping through unsealed headers. The low pump level is — 9
ft below top of berm. The lagoon digester cover should be supported by the lagoon
liquid when not inflated. Dropping the lagoon liquid level too low may lead to an
unsupported cover and possible cover stretching and cover damage. Recommended
operation level is 3-4 ft below top of berm to ensure adequate digester biomethane
production and ensure that the level does not exceed 2 ft below top of berm at any time
during operational deviances.
The digester liquid level should be monitored daily. Transfer pumps can be operated
manually or in timer mode. Normally, timer mode should be used as the pumps will
not normally run continuously. During the biogas production season, the liquid level
should be maintained at a higher level. As the production season slows down in the fall,

the digester liquid level should be pumped down slowly to low pump level. This will
allow the maximum amount of manure to be stored during the off season and should be
allowed to fill back up to high level, before starting the transfer pump and discharging
liquid to evaporative lagoons.
Digester Cover Operation
8.1.1
The digester covers are a fully welded system that is integral with the lagoon liners.
Because of soil permeability, the 60-mil liner is utilized and fully welded to the 80-mil
lagoon cover at the perimeter. All cover, liner, and anchor trench sheet material is
HDPE which provides material toughness, flexibility, UV resistance, and water/gas
impermeability. The cover uses 6" grout filled HDPE piping at both the laterals and
center anchor trench. The Laterals are spaced on the order of 42-44 ft apart along the
entire length of the cover and are used to restrain gas movement from one side of the
cover to the other and avoid fast movement of the cover. Laterals are only effective
when they are substantially laying on the digester water operating level. The center
trench is comprised of two parallel pipes that run the center axis along the length. The
center trench is used to both restrain the cover upward movement and to provide an
area in which incident rainwater collects for easier pumping. An 8" corrugated
perimeter biogas collection header is installed around the entire circumference of the
digester cover to ensure generally equal gas inflation around the perimeter during low
gas production and low cover inflation.
The digester cover is a volumetric storage vessel, not a pressure vessel. The cover is
designed to contain the biogas emanating from the digester surface for collection into
the perimeter biogas header. The pressure under the cover operates at 0.0" w.c. (Water
column) to approximately 0.3" w.c. Pressure is not measured as it is immaterial to
operations.
In the event of power outage or emergency, there are two (2) 6" flanged emergency vent
ports directly on the cover, opposite of the swine barns. These ports have lug butterfly
valves and should be used with proper venting apparatus to ensure that the biogas is
vented at an elevation high enough to support safe operator opening and closure of the
valves.
Proper inflation of the digesters is critical to the reliable operation of the plant. A low
level of inflation ensures that ingress of air doesn't occur into the biogas which would
contaminate the gas with nitrogen and oxygen. 100% full inflation ensures that the
covers are in an optimal state for 24-hour net heat gain by the digester and prepared for
normal atmospheric wind conditions. This site has an annual hurricane season which
will involve strong storms and large amounts of rain. The direction below, addresses
normal, winter season, and hurricane season that are predicted. It is ultimately important
to continually monitor weather forecasts at least 5 days out and make any adjustments
in cover inflation in advance.

The operations group should keep in mind the following items that affect the
performance of the cover.
• Laterals and center anchor trench piping is designed to control the movement
of the cover in all wind conditions. The grid of piping reinforces the cover in
both directions and also acts as a labyrinth in which gas has to pass when
moving during wind conditions, thus slowing the gas velocity and cover
movement.
• More cover contact with the water allows the cover to survive high wind
conditions due to the fact that water surface tension anchors the cover and there
is less volume of gas to move around the cover. Taut cover material also allows
the cover to withstand higher wind conditions.
• Less cover rise above the top of berm reduces the area of cover that wind exerts
force on. Less cover rise around the perimeter also reduces the cover profile
which in turn reduces the Bernoulli lifting mechanism on the cover in high
wind conditions (similar to a plane wing profile)
• HDPE has a relatively large coefficient of thermal expansion. The cover will
be much hotter during the day with sunlight exposure than at nighttime. Also,
radiant heat loss at night will condense water in the biogas space under the
cover, also reducing the total volume of gas under the cover. Methane, Carbon
Dioxide, and Hydrogen Sulfide do not condense but do decrease in volume as
an ideal gas. The volumetric difference in gas over a 24-hour period day to
night is due to the molar water volume in the biogas and biogas temperature
under the cover. The cover and laterals are designed for expansion and
contraction over all biogas ambient dry bulb temperatures between high and
low pump digester levels.
• As the perimeter of the digester is inflated less, less water will run off the cover
around the perimeter. This is beneficial to reduce the possibility of erosion of
the digester berms. Covers are easily pumped off with the Mixing Pumps to a
location several hundred feet from the berm.
The following digester cover operating guidance should be followed by plant operations
group:
1. In all operating conditions, the center rain trench piping shall be fully, 100%,
laying on the digester water surface.
2. In all operating conditions, the laterals shall be at minimum, substantially
laying on the digester water surface. Per operating modes below, maximum
15' of lateral at either end shall be suspended above the surface of the cover.
3. Digesters will produce gas at different rates. The blowers and A2000 piping is
designed to transfer gas between covers to maintain cover inflations within the
cover operating modes below while conserving biogas.
4. Anemometers are installed on the plant and accessible through Ignition. Each
Anemometer indicates wind speed up to 90mph and wind direction. Data is
recorded in the historian. Operators will monitor wind speed and use as

necessary to refine operations compared with predicted winds at remote towns
based on the actual farm surrounding geography.
5. With A3000 fully operational, there is no reason to inventory biogas under the
covers beyond the operating modes detailed below.
Operating Modes:
1. Normal Operation:
a. Cover inflation around the perimeter is no higher than 6' above top of
berm. Inflation will generally vary between 3' to 6' based on wind
speed and direction.
b. Laterals are substantially on the digester water surface with end 10-15'
suspended and end cap at —2' off of liquid surface.
c. Gas cover between laterals is pillowed at nominal 2-4' above water
surface at peaks between the laterals.
d. Cover is tensioned but not tight. The cover will incrementally move in
the wind but with gentle local rolling effect.
e. This mode is applicable for winds sustained and gusts up to 50 mph
from all directions.
2. Winter Season Operation:
a. Cover inflation around the perimeter is no higher than 6' above top of
berm. Inflation will be generally 3' to 5' based on wind speed and
direction.
b. Laterals are fully on the digester water surface, including end cap.
c. Gas cover between laterals is not pillowed and flat on the water with
the exception of naturally occurring and sporadic cover rolls/channels.
d. Cover is tensioned but not tight. The cover will incrementally move in
the wind but with gentle local rolling effect.
e. This mode is applicable for winds sustained and gusts up to 65 mph
from all directions.
3. Hurricane / High Wind / Intense Storm Predicted:
a. Cover inflation around the perimeter is no higher than 3' above top of
berm. Nominal inflation above top of berm is 1.5' to 2'.
b. Laterals are fully on the digester water surface, including end cap.
c. Gas cover between laterals is not pillowed and flat on the water with
the exception of naturally occurring and sporadic cover rolls/channels.
d. Cover is tensioned but not tight. The cover will incrementally move in
the wind but with local rolling effect.
e. Cover will be flat extending from the ends of the laterals towards the
anchor trench for at least 20'.
f. This mode is applicable for winds sustained and gusts above 65 mph
from all directions. If winds are expected to exceed 75 mph, the
blowers (preferentially) and or emergency vents (if required) should be
used to evacuate substantially all gas.

Daily Checks
8.2.1
• Visually inspect the digester water operation level to ensure 3-4 ft of freeboard.
Work with the farm to adjust timers if required to bring the level back into target
range.
• Visually inspect the digester cover and quantify inflation level and laterals
position.
• Visually inspect and quantify area of digester cover occupied by water. Utilize
pumping systems to remove surface water from the center anchor trench.
Weekly Checks
8.3.1
Walk perimeter of digester checking for:
• Leaks via a gas monitor or methane detection device around the base of the
cover and the anchor trench. Use of soapy water from an orchard sprayer may
also be used to detect leaks during cool cover conditions and still wind.
• Torn ballast straps or laterals that are not aligned straight.
• Settling or erosion around berm
• Any running equipment for an uncharacteristic operating state (noise/vibration)
• Sample cover rainwater to determine if it is "hot" aka contains dissolved
ammonia because contaminated cover water is an indication of a possible
digester cover leak and will need to be pumped under the cover.
• Trash and foreign matter on the cover can cause problems with normal
operation. If debris becomes wedged between the ballast weight and cover it is
possible for punctures to occur. Additionally, foreign matter can cause the rain
collection channels to become blocked and disrupt flow of the rainwater. All
operators and contractors working on top of the digester should be cognizant
of the perimeter rock and make sure not to kick the rock into the digester.
Furthermore, a yearly pre -season inspection should occur to inspect for and
remove any debris along the entire length of ballasts.

Safety Practices for On -Farm Anaerobic Digestion Systems
1.0 INTRODUCTION
Several safety hazards exist when converting manure and organic residuals (non -farm
feedstock) into energy using anaerobic digestion (AD) technology. These hazards can cause
serious bodily harm and in some
circumstances, can be fatal. Common hazards I Figure 1: Safety signage on AD feed system
associated with AD systems include drowning,
electric shock, and noise exposure. However,
biogas and its constituents, many of which are
colorless and odorless, can unknowingly
expose operators and visitors to hazards such
as asphyxiation and burns due the flammable
nature of methane. Workers must take
proper precautions when handling and storing
organic material and managing the
production of electricity and combustible
gases.
The purpose of this document is to identify
the major hazards associated with an AD
facility and outline basic practices that will
help maintain a safe and successful working
environment. The intended audience for this
guide is owners and operators, and the guide
is not intended to replace safety training or
instruction, but rather enhance it.
2.0 SAFETY HAZARDS FOR
ANAEROBIC DIGESTION
The following sections identify major hazards that can exist with an AD facility. These include:
• General safety precautions
• Hazards associated with biogas
• Confined space entry
• Electrical system hazards
Figure 1 shows a feed hopper for an anaerobic digester with a dozen warning signs, including
fall, entanglement, and explosion potential.

Safety Practices for On -Farm Anaerobic Digestion Systems
2.1 GENERAL SAFETY PRECAUTIONS
The following sections describe general safety concerns associated with AD facilities.
2.1.1 Drowning
Liquid tanks and ponds for storage pose a drowning threat.
Whenever a drowning potential exists, ring buoys, ropes, or
ladders should be readily available for rescue purposes
(Occupational Safety and Health Administration [OSHA],
2002). The drowning risk is highest when employees are
servicing equipment located in digester or storage tanks.
Accidental drowning can occur when people unfamiliar with
the farm and manure handling system mistakenly enter
storage structures. Slipping on a synthetic liner or walking
on crusted manure storage are examples of situations that
can lead to accidental drowning. OSHA suggests posting
signs similar to the one shown in Figure 2 and erecting
fences around manure storage structures to reduce the
potential of an individual or animal unknowingly entering
one.
Figure 2: Manure storage

Spanish

DE ETIt-ROL

Jrs_
If an individual is drowning, the first step should be to call 911, followed by a rescue attempt
using a life preserver, rope, or ladder. The presence of biogas—an asphyxiant that can cause a
person to pass out —can increase the potential of manure storage drowning. (Biogas hazards
are discussed in greater detail in Section 2.3.) Individuals attempting to rescue a drowning
individual should never enter a manure storage structure because they could also be overcome
by the poor air quality.
2.1.2 Fall protection
Serious injuries can result from falls of any distance. When possible, employees should perform
maintenance work from the ground. At most AD facilities, however, multiple elevated locations
are present. For example, equipment on the top of aboveground AD tanks are 10 to 25 feet off
the ground. According to the OSHA general industry standard any "time a worker is at a height
of four feet or more, the worker is at risk and needs to be protected" (OSHA, 2008A). Fall
protection, such as guardrails, a safety harness (also discussed in Section 2.2.4), and self -
retracting lifelines, should be used when an employee is above the 4-foot threshold (API, 2006).
The enclosed fixed ladder and guardrail system on the feedstock storage tank shown in Figure 3
complies with OSHA fall protection standards.

Safety Practices for On -Farm Anaerobic Digestion Systems
Another common example of a fall risk is shown in
Figure 4, where a ladder is leaned against a feedstock
storage tank. The two concerns with the situation
presented in Figure 4 are: (1) the tank height is
approximately 10 feet and (2) there are no securing
devices or slip resistant feet on the ladder, nor is
there a rope to secure the top. When ladders are
used to access elevated equipment, they should be
secured and supervised at all times. Once the ladder
is no longer needed, it should be removed.
2.1.3 Burns
Throughout an AD facility, pipes containing hot fluids
or exhaust gas can pose potential burn hazards.
Other potential sources of burns are heat exchangers,
boilers, pumps, or engine generators, where
temperatures can exceed 160°F. Simply rubbing up
against a heat exchanger or accidently placing a hand
on a hot pipe can result in serious burns. All
Figure 3: Permanent ladder and
guardrail on feedstock storage tank
employees and visitors to the AD facility should be cautioned not to touch any equipment or
pipelines.
When possible, hot surfaces should be identified as burn hazards, and all pipes should be
clearly labeled to indicate the contents,
Figure 4: Ladder leaning on feedstock storage
tank
flow direction, temperature, and pressure.
Insulation should be used to encase the
pipe and reduce the potential for
accidental burns. Figures 5 and 6 provide
examples of pipeline insulation and
labeling.
2.1.4 Entanglement hazard
Pumps, augers, impeller mixers, chains,
drive shafts, and other machinery pose
entanglement hazards due to pinch points
and other moving parts. In most AD
systems, the primary exposure to
entanglement is the unguarded driveshaft
3

Safety Practices for On -Farm Anaerobic Digestion Systems
of a pump. To reduce the entanglement risk,
all equipment safety guards should be in
place and individuals should tie back long
hair and avoid wearing loose -fitting clothing
and jewelry.
2.1.5 Feedstock and digestate spills
Figure 5: Insulated and labeled hot water
pipes
Feedstock (any organic material entering the eYi URN
digester) and digestate (any material exiting E
the digester) should be carefully transferred
and contained. In the event of a major ` I
feedstock or digestate spill, workers should
exercise caution when containing the f --
material. The first step should be to control pp��
the source causing the spill. Once this is'55'°`U°
achieved, workers should contain the spill by V
constructing temporary containment
structures around the affected area. Excavation equipment such as bulldozers and backhoes
should be readily available for this purpose. Isolating the spill reduces potential damage to
nearby buildings and contamination of surface
Figure 6: Biogas pipeline indicating waters and sensitive areas. After containing the
temperature and flow direction spill, the facility should notify the proper
authorities (as defined by state -specific permits), to
comply with all applicable local, state, and federal
regulations. For non -farm feedstocks, such as food
waste, the spill -reporting agency should be clearly
identified on all records related to the material,
including material safety data sheets (MSDS) and
manifest logs indicating the date, quantity, and
material (feedstock) brought onto the farm. The
final step in spill response is site cleanup and
restoration.
2.1.6 Mechanical failures
In the event of a mechanical failure, workers should reference the vendor manuals to
troubleshoot the issue. Vendor manuals for mechanical machinery should be organized and
included in the emergency action plan, which is discussed in Section 3.1. Only trained staff
4

Safety Practices for On -Farm Anaerobic Digestion Systems
should be permitted to repair digester equipment. Operators should use lockout/tagout
procedures (see Section 2.1.7) during all mechanical equipment repairs.
To avoid mechanical failures, the system operator, with support from the technology provider,
should develop a preventative maintenance manual for the site.
2.1.7 Lockout/ragout
According to OSHA standard 29 CFR 1910.147,
lockout/tagout refers to the specific "practices and
procedures to safeguard employees from the
unexpected energization or startup of machinery and
equipment, or the release of hazardous energy during
service or maintenance activities" (OSHA, 2007A).
Simply stated, before an employee services a piece of
electrical equipment, the power supply should be
turned off and the employee should place a padlock on
the power supply. The padlock serves to prevent
someone else from accidently re -energizing the
equipment being serviced. The lock should have a tag
on it identifying the individual who locked out the
Figure 7: Electrical panel turned off
and locked out
equipment. In Figure 7, one of the four electrical breakers shown is turned off (disengaged) and
locked out. Once a piece of equipment has been locked out, the only individual with the
authority to unlock that piece of equipment is the person who initially locked it out.
Employees should follow this practice every time they service any electrical or electrically
powered equipment. OSHA estimates that compliance with lockout/tagout procedures
prevents an estimated 120 fatalities and 50,000 injuries each year in the United States (2007A).
2.1.8 Ignition sources
Biogas generated during anaerobic digestion is flammable. Over the past couple of years,
several AD systems have been damaged or destroyed by fires fueled with biogas. While no
specific setbacks or standards have been established for biogas, facilities should observe
standards for similar systems. The National Fire Protection Association (NFPA) has established a
range of setback distances for liquid propane (LP) fuel based on storage capacity (2009). For LP
gas, the setback ranges from 10 feet for small storage devices (<500 gal water capacity) to 100
feet for large storage systems (>70,000 gal water capacity).

Safety Practices for On -Farm Anaerobic Digestion Systems
Smoking and open flames should be prohibited in
the general vicinity of the digester and a setback
distance of 25 to 50 feet is suggested for all
possible ignition sources to reduce the potential
for fire or explosion. Ignition sources can include
(but are not limited to) light switches, electric
motors, pilot flames, and cell phones. Facilities
should designate smoking areas at least 50 feet
from the digester system to ensure that visitors
and employees do not inadvertently create an
ignition source. Signs, like the one shown in Figure
8, should also be used to warn all individuals of
the explosion or fire risk associated with AD
systems.
The National Electric Code (NEC, 2005) dictates
that electrical wiring near combustible gas must
conform with the Class 1, Division 1 hazardous
location standard. Biogas is combustible, so the
Figure 8: Explosion potential sign
hazardous location standard should be applied to AD systems' electrical wiring.
For repairs requiring open flames or electric spark, ventilation should be provided such that
methane levels are maintained below a safe level, as discussed in Section 2.3.3.
Figure 9: Gen set enclosure with hearing
protection warning sign
2.1.9 Noise levels
Exposure to high levels of noise can
result in discomfort or short-term
hearing loss. In extreme cases, or if the
noise exposure occurs over a long
period of time, permanent hearing loss
can occur. The main source of high
noise levels is the engine generator set
(gen set). Actual decibel (dB) levels
produced at an AD facility will differ due
to varying acoustical settings, but a gen
set can produce between 100 —140 dB
(Fenton, 2011). The facility is required
to supply noise protection devices, such

Safety Practices for On -Farm Anaerobic Digestion Systems
as earplugs, to employees and visitors who are exposed to high noise levels (OSHA, 200813) (See
Table 1). Handheld decibel meters are widely available and provide an inexpensive method to
quickly determine the noise level. Also, OSHA encourages posting signs indicating "hearing
protection is required in this area." (See Figure 9).

2.2 CONFINED SPACE ENTRY
Constituents of biogas, including carbon dioxide, methane, and hydrogen sulfide, present the
potential for both asphyxiation and fire or explosion in confined spaces. It is important to
remember that even a few gallons of manure or other organic material in a tank or confined
space can pose a serious health risk under
Figure 10: Basic confined space warning sign
the right conditions. A recent example of
confined space entry fatality occurred in
July of 2010 when two farm employees died
while cleaning a storage tank similar to the
one shown in Figure 4 (Michigan
Department of Energy, Labor and Economic
Growth [MEDLEG]). Signs should be used to
alert employees and visitors when confined
space entry risks exist. Figure 10 shows an
example of a standard confined space
warning sign. The following background

information and guidelines are intended to promote a safe working environment when
confined space is involved.
7

Safety Practices for On -Farm Anaerobic Digestion Systems
2.2.1 Definition
"Confined space" is defined by OSHA as "having a limited or restricted means of entry or exit;
large enough to bodily enter and perform tasks; and lastly, not designed for continuous
occupancy." Currently, state -by -state standards vary for permit -required confined spaces
training for agriculture; however, confined spaces are widely recognized as a common hazard.
Confined spaces include, but are not limited to, tanks, pits, silos, underground vaults, storage
bins, and manholes (MDELEG, 2010).
2.2.2 Confined space training, certification, and rescue plan
Employees associated with AD systems or who manage organic residuals MUST be trained in
confined space entry to maintain a safe working environment (Gould, 2010). Several cases have
resulted in fatalities due to a lack of understanding of the hazards associated with confined
spaces. As discussed earlier, two farm employees died when they were overcome by a lack of
oxygen while cleaning a feedstock storage tank (MDELEG, 2010). The employees were power
washing a tank that contained only 6 to 8 inches of molasses residue, which had sat unused for
five to six months. By conducting basic employee education and strictly adhering to OSHA
confined space entry guidelines, facilities can provide a safe working environment for farm
employees.
Currently, OSHA does not require farms to offer
specific training for confined space entry;
however, it is the employer's responsibility to
educate employees in order to maintain a safe
working environment. When entering a confined
space, the "buddy system" should be used, in
which any person entering a confined space is
monitored from a safe distance by a second
person. The employee entering the confined
space must wear a harness attached to a
retraction device that the second employee can
activate to pull the individual to safety in an
emergency.
The facility should develop a rescue plan for
emergency confined space entry situations. This
plan should describe the use of the safety
Figure 11: Handheld multi -gas detectors
a
pq
Images fro m Goo gle images
equipment in emergency situations, the actions to be taken, and the personnel responsible for
each action. The plan may also include training and certification information.
RI

Safety Practices for On -Farm Anaerobic Digestion Systems
2.2.3 Inspect atmosphere prior to entry
Before entering a confined space, a worker must test the atmosphere inside the space, as
required by OSHA general industry standard 1910.146 (1998). The person can perform this
testing using a handheld multi -gas detector capable of detecting oxygen, carbon monoxide,
hydrogen sulfide, and lower explosive limits (LEL) levels. Several models of multi -gas detectors
are shown in Figure 11. When testing the atmosphere within a confined space, the employee
should remain outside in a safe location. Many multi -gas detectors are equipped with an
extension hose for this purpose.
In compliance with standards (OSHA, 1998), the employee should test for the following:
Oxygen level: above 19.5 percent by volume air
2. Methane: below 5 percent by volume of air
3. Hydrogen sulfide level: below 20 parts per million (ppm)
If any of the above conditions are not met, the atmosphere is deemed hazardous and should
not be entered by any personnel until forced ventilation has eliminated the hazardous
conditions. During entry, continuous ventilation with an explosion -proof blower will ensure that
fresh air is displacing any hazardous air that may be trapped in the confined space. Workers
must maintain and calibrate this equipment
according to the manufacturer's
recommendation in order to effectively monitor
atmospheric conditions.
2.2.4 Safety equipment
When entering a confined space, an employee
should wear a safety harness attached to a
winch or pulley outside of the pit. Examples of
safety harnesses and a winch are shown in
Figure 12. This safety precaution, allows a
coworker to assist a trapped employee without
having to enter the space in the event of an
emergency.
A self-contained breathing apparatus (SCBA)
should be used only in emergency situations.
Figure 12: Safety harnesses, ropes, and a
chain fall at an AD facility

Safety Practices for On -Farm Anaerobic Digestion Systems
Figure 13 shows a basic backpack -style SCBA with fitted facemask. Any employee using a SCBA
must be properly trained and fitted for using the equipment. For an individual to become
certified in confined space entry, they should consult the
State approved OSHA administration.
2.3 HAZARDS ASSOCIATED WITH BIOGAS
AD biogas is composed of three main constituents:
methane, hydrogen sulfide, and carbon dioxide. Each of
these gases can be dangerous under certain circumstances.
Common hazards associated with biogas include
asphyxiation and fire or explosion potential.
Overall, it is always a good idea to test the atmosphere
when biogas may be present as well as maintain proper
ventilation. Workers can use a handheld multi -gas detector,
similar to one of those shown in Figure 11, to determine if
hazardous levels of biogas are present. Low-cost detectors
will simply identify dangerous level of biogas, while higher
end detectors can report specific concentrations of the
primary biogas components.
2.3.1 Asphyxiants
Gases that prevent the uptake of oxygen into human cells
Figure 13: Self-contained
breathing apparatus
Irnage fro rnhttlX;' ,-r::::.enriSUPPI .corn/
are referred to as asphyxiants. There are two categories of
asphyxiants: simple and chemical. A simple asphyxiant displaces oxygen, and chemical
asphyxiants "reduce the body's ability to absorb, transport, or utilize inhaled oxygen.
Asphyxiants are often active at very low concentrations (a few ppm)" (Lawrence Berkeley
National Laboratory, 2008). Asphyxiant gases are present wherever there is storage of an
organic material; therefore, manure pits or any other areas for organic material storage
become potentially dangerous. Following are the various asphyxiants that are typical
constituents of biogas.
• Simple asphyxiants —carbon dioxide and methane
• Chemical asphyxiants — ammonia and hydrogen sulfide
10

Safety Practices for On -Farm Anaerobic Digestion Systems
2.3.2 Immediately dangerous to life and health
Within confined spaces and other covered areas, the potential exists for atmospheric
concentrations to develop that become immediately dangerous to life and health (IDLH). An
IDLH condition can be defined as an atmospheric concentration of any toxic, corrosive, or
asphyxiant substance (simple or chemical) that "poses an immediate threat to life or would
cause irreversible or delayed adverse health effects or would interfere with an individual's
ability to escape from a dangerous atmosphere" (OSHA, 2008C). Following are the main IDLH
concerns when handling the production of biogas (Center
for Disease Control and Prevention, 1995).
• Oxygen deficiency — less than 19.5 percent by
volume air
• Hydrogen sulfide — more than 100 ppm
• Ammonia — more than 300 ppm
• Carbon dioxide — more than 40,000 ppm
Signs similar to the one shown in Figure 14 should be used
to alert employees and visitors of the potential for IDLH
conditions. Areas prone to these conditions include
structures housing the gen set or boiler, below grade pump
chambers, and biogas storage devices.

ENTER PITONLY WITH:
• SELF-CONTAINED AIR SUPPLY
• VENTILATION
• RESCUE HARNESS, MECHANICAL
LIFT, STAND-BY PERSON
A simple and convenient way to ensure the safety of an area's atmosphere is by installing a
wall -mounted sensor that can detect hazardous gases (e.g., methane, LEL, hydrogen sulfide,
carbon monoxide). In the event that a hazardous gas sensor is triggered, the emergency action
plan (see Section 3) should be implemented.
2.3.3 Explosion potential
Methane, the main component of biogas, is flammable
when it mixes with air. Upper and lower explosive limits
(LEL) are established to provide an identifiable range of
concentrations that will produce a flash fire when an
ignition source is presented. The LEL is often referred to as
a flammable limit. For methane, the lower and upper
explosive limit is 5 percent and 15 percent by volume of
air, respectively (Linde Gas LLC, 1995).

Safety Practices for On -Farm Anaerobic Digestion Systems
2.4 ELECTRICAL SYSTEM HAZARDS
The generation of large quantities of electricity at an AD facility creates electrical hazards, most
of which can be found near the gen set, transformer, and electrical panels. The only personnel
with the authority to service and repair electrical systems are licensed electricians. In addition,
the facility should post signs identifying general electrical hazards near the electrical generation
system (see Figure 15 for an example of basic signage).
2.4.1 High voltage
Any electrical source above 600 volts is
considered high voltage (NEC, 2005). Typically,
transmission lines from the transformer are the
source of the highest voltage on a farm. A
transformer is a piece of machinery used to
increase the voltage, allowing for more efficient
transport of the electricity. When dealing with
such high voltage, the main hazard is contact
with exposed leads, which could be fatal. Figure
16 shows exposed lead transformers commonly
used on utility poles. Ground -mounted
transformers used on farms and at AD facilities
are typically enclosed like the one shown in
Figure 16: Standard electrical
transformer with exposed leads
Figure 17. Enclosed transformers should remain sealed
Figure 17: Enclosed electrical and locked at all times, and only a licensed electrician
transformer should perform transformer maintenance.
V; 2.4.2 Low voltage
All electrical sources less than 600 volts are considered
-----E n low voltage (NEC, 2005). Typically, switches,
- controllers, fuses, breakers, wall outlets, and electrical
panels are considered low -voltage devices. One major
hazard associated with electrical panels is arcing, which
" occurs when electricity from an energized source
jumps a gap of air and discharges into an adjacent conductive surface, typically metal. If an
individual happens to be in the pathway of the arc, they can be seriously burned or killed. Cover
plates are used to contain arcing by shielding the employee from any potential harm.
Therefore, the facility should ensure that the proper cover plates are intact and correctly in
place on the panel or outlet.
12

Safety Practices for On -Farm Anaerobic Digestion Systems
2.4.3 Electrical fires
In the event of an electrical fire, the person fighting the fire should use an ABC classified multi-
purpose fire extinguisher rather than a water -based fire extinguisher, which could result in
electrocution. If possible, the electricity should be shut off to the facility before fighting the fire.
The facility should train operators to identify the difference between electrical fires and
ordinary combustible fires (Wallenwine, 2011).
3.0 MAINTAINING A SAFE WORKING ENVIRONMENT
AD facilities can provide a safe working environment, as long as proper safety measures are
taken. The following sections present recommended steps for maintaining a safe working
environment at AD facilities, adapted from the self -assessment guide prepared by Nellie Brown
(2007), titled "Conducting a Safety Walk-through on a Farm: Hazards of the Manure Handling
System, Anaerobic Digester, and Biogas Handling System" and the emergency action plan
requirements of the National Pollution Discharge Elimination System (NPDES) program.
3.1 EMERGENCY ACTION PLAN
In most states, AD facilities are required to have emergency action plans (EAP) as part of their
NPDES permits. A major objective of an EAP is to develop response protocols to specific
emergencies so that if an accident occurs the facility will conduct the appropriate actions in the
correct sequence. As a general recommendation, each situation should be broken down into
the following components.
Assess the extent of damage in the following order:
a. Human health
b. Environmental health
C. Mechanical integrity
2. Correct the problem immediately if possible.
3. Contact the appropriate agencies and personnel to resolve the problem.
The contents of an EAP should be well organized in a binder or an electronic file and distributed
to all employees so that they are informed of the proper safety protocols. The facility should
provide local emergency departments with a copy of the EAP and invite them for a tour of the
operation so they can become familiar with the facility. Also, the facility should post a copy in a
highly visible area where visitors enter the facility.
13

Safety Practices for On -Farm Anaerobic Digestion Systems
To maintain an effective EAP, the facility should perform an annual review of the document to
keep it up to date. Conducting annual training sessions will ensure that employees have a basic
understanding of the EAP. The following sections present the recommended content to be
included in an EAP.
3.1.1 Directions to AD facility
Often, the AD facility is not clearly visible from the main road, especially if it is located in an
agricultural setting. Therefore, detailed driving directions from the closest major road,
intersection, or town to the physical location of the AD facility should be included in the EAP.
3.1.2 Contact information
The EAP should provide a list of emergency and non -emergency contacts, including the job title
and cell phone number of each person. Recommended contacts are:
• Farm or AD owner
• AD operators
• Emergency and nonemergency responders
o Fire department
o Poison control
o Law enforcement
o Hospital
• Electric and gas utilities
• Contractors
o Electrical
o Excavation
o Mechanical
• State health and safety officials
Contact information should identify the appropriate after-hours emergency contact
information as well. The contact list should be posted in multiple locations throughout the AD
facility and farm so that in the event of an emergency, there is quick and easy access to this
information. It is important that the contact list be updated routinely to make sure all
information is current.
14

Safety Practices for On -Farm Anaerobic Digestion Systems
In many rural locations, calling 911 may not be the best method for reaching emergency
responders. On an annual basis, the AD operator or owner should host a site tour with the local
fire, ambulance, and sheriff departments. The purpose of this tour would be to familiarize
emergency responders with the site and system, as well as identify the most direct contact
method in the event of an emergency.
3.1.3 Site map
The EAP should include a detailed site map that identifies and labels relevant structures and
major equipment (e.g., flare, gen set, boiler) at the AD facility, as well as the location of
emergency equipment. It should also clearly identify the locations of biogas supply shutoff
valves and the primary electrical disconnect and control panel.
3.1.4 State and local health and safety requirements
The EAP should include the federal and state health and safety regulations for the facility, as
well as all OSHA documents, guidelines, and certifications, including confined space entry
training documents. In addition, MSDS for non -farm feedstock and any chemical or biological
additives should be included in the EAP and posted at the facility so that employees can have
quick access to the information.
3.1.5 Equipment vendor manuals
The EAP should include the vendor manuals for all equipment at the AD facility. These materials
should be well organized so that in the case of a mechanical failure, an operator can locate and
reference a specific vendor manual quickly and easily.
3.2 SAFETY AND EMERGENCY EQUIPMENT
The following sections list recommended supplies and equipment an AD facility should have
available for normal daily operation or in the event of an emergency. The list is divided into
supplies and equipment to be maintained on site, so employees can access it within minutes,
and equipment that should be locally available and could be delivered to the site within a few
hours. A logbook of equipment inspections and expiration dates and the equipment manuals
should be located with the safety equipment.
3.2.1 Anaerobic digester facility (onsite)
• Personal protective equipment
o Gloves
o Safety glasses
15

Safety Practices for On -Farm Anaerobic Digestion Systems
o Hearing protection
o SCBA (provided employees are properly trained and fitted for using the
equipment).
• First aid kit
• Fire extinguishers (ABC)
• Explosion -proof instruments (e.g., flashlight, ventilation blower, hand tools)
• Rigging equipment for rescue of a person
o Hoist, winch, or pulley
o Safety harness
• Multi -gas detector with extension hose
• Ring buoy
• Shovel
3.2.2 Locally (able to be onsite within a few hours)
• Excavation equipment (e.g., bull dozer, backhoe, excavator)
• SCBA and trained individual
3.2.3 Baseline environmental conditions
During startup and for the first 6 to 12 months of use, operators should collect operational
parameters and air quality measurements around the AD facility on a weekly basis to establish
baseline/normal operating conditions. Basic operational parameters should include pressure
and temperature readings on pipelines where gauges are installed. Using a handheld multi -gas
meter, employees should check the air quality inside all structures or rooms, along with the
conditions in below -grade pump chambers, near the base of digester tanks, and along biogas
pipelines. At a minimum, the concentration levels of hydrogen sulfide, carbon monoxide, and
methane should be measured and recorded. By establishing baseline operating conditions, the
AD operator has a point of reference for troubleshooting operational problems and
determining when hazardous conditions are developing or already exist.
16

Safety Practices for On -Farm Anaerobic Digestion Systems
3.3 ELECTRICAL
The following section provides common practices to help maintain safety by reducing the
potential for electrical hazards that may occur at an AD facility.
3.3.1 Daily inspections
The AD facility should instruct operators to perform
daily inspections of the electrical system. This
inspection should include, but not be limited to, the
following:
• Conduit connections to panels
• Panel cover integrity
• Conduit integrity
• Exposed and damaged wires
• Corrosion of wires
• Signs of electrical overheating
If there is any sign of the aforementioned problems,
operators should contact the site manager or a
licensed electrician to resolve the issue. Figure 18
shows a corroded electrical control panel that an
Figure 18: Corrosion on an electrical
control panel
operator should identify for repair during daily inspections. The operator should not attempt to
fix the problem unless he or she is the appointed licensed electrician for the facility.
3.3.2 Switches, controllers, fuses, and breaker panels
Electrical panels should not be obstructed by any object that would impede the accessibility of
the panel itself. For example, temporarily placing a 55-gallon drum below a circuit breaker or
installing a pump below a control panel would impede accessibility. Moreover, electrical panels
should always be visible so that emergency responders can locate them easily. This becomes
imperative when an electrician unfamiliar with the facility needs to turn off the power quickly
in an emergency situation.
All electrical panels should be well labeled and include an accurate, up-to-date copy of the
wiring diagram (Wallenwine, 2011). Additional copies of the wiring diagram should be
maintained off site and digitally in the event that a copy is lost, damaged, or destroyed. The
facility should check the local electrical code to determine the clearance required around the
electrical panel.
17

Safety Practices for On -Farm Anaerobic Digestion Systems
3.3.3 Roles of operators
An operator inspects and observes any defective electrical problems but does not perform any
electrical maintenance. A licensed electrical engineer appointed by the AD facility is responsible
for maintenance and repair of electrical problems.
3.3.4 Visitors on site
Unattended facilities associated with the AD system should be locked to limit risk to individuals
unfamiliar with the surroundings and to ensure that the system continues to operate efficiently.
Employees familiar with the AD system should escort visitors at all times. Visitors to an AD
facility are not to operate any switches, controllers, or other electrical functions, including light
switches.
3.4 PERSONAL PROTECTIVE EQUIPMENT
Personnel at an AD facility should be provided with proper -fitting personal protective
equipment (PPE). The employer is responsible for communicating and educating the employees
on the proper use of PPE (OSHA, 20076). At a minimum, OSHA recommends protective gloves,
splash -proof goggles, hearing protection, and steel toe shoes for employees associated with the
digester system. For visitors to the facility, safety glasses and hearing protection should be
available and worn while on site.
3.5 ACCIDENT PREVENTION SIGNS AND TAGS
Accident prevention signs and tags should be visible at all times when work is being performed
where a hazard may be present and should be removed or covered promptly when the hazards
no longer exist. Also, caution signs should be designed to be understood by non-English
speakers. The EAP should include resources documenting where proper signs or tags can be
obtained for potential facility hazards. A variety of OSHA -approved accident prevention signs
are shown in Figure 19.

3.6 PERSONNEL TRAINING REQUIREMENTS
Annually, the facility should review the EAP with all employees associated with the AD system
and new hires should go through safety and system operation training before being permitted
to work at the AD facility. In addition, owners of systems should be aware of OSHA
requirements and comply with employee training requirements.
4.0 CONCLUSION
Anaerobic digestion provides a real opportunity to address farm -related environmental
concerns, generate renewable energy, and diversify farm products. It is important to realize,
however, that AD systems pose unique challenges and safety risks not experienced on typical
farms. These risks can be mitigated by practical measures, including educating employees about
the risks associated with the system, implementing strict safety procedures, and having a
detailed and up to date EAP that employees are familiar with. Ensuring a safe environment
around the AD facility will protect employees and visitors while enhancing the overall
performance of the digester.

DATUM INFORMATION
The projection used in the preparation of this map was the North Carolina
State Plane (FIPSZONE 3200). The horizontal datum was the North American
Datum of 1983, GRS80 ellipsoid. Differences in datum, ellipsoid, projection, or
Universal Transverse Mercator zones used in the production of FIRMs for adjacent
jurisdictions may result in slight positional differences in map features across
jurisdictional boundaries. These differences do not affect the accuracy of this
FIRM. All coordinates on this map are in U.S. Survey Feet, where
1 U.S. Survey Foot = 1200/3937 Meters.
Flood elevations on this map are referenced to the North American Vertical
Datum of 1988 (NAVD 88). These flood elevations must be compared to structure
and ground elevations referenced to the same vertical datum. An average
offset between NAVD 88 and the National Geodetic Vertical Datum of 1929
(NGVD 29) has been computed for each North Carolina county. This offset was
then applied to the NGVD 29 flood elevations that were not revised during the
creation of this statewide format FIRM. The offsets for each county shown on
this FIRM panel are shown in the vertical datum offset table below. Where a
county boundary and a flooding source with unrevised NGVD 29 flood elevations
are coincident, an individual offset has been calculated and applied during the
creation of this statewide format FIRM. See Section 6.1 of the accompanying
Flood Insurance Study report to obtain further information on the conversion
of elevations between NAVD 88 and NGVD 29. To obtain current elevation,
description, and/or location information for bench marks shown on this map,
please contact the North Carolina Geodetic Survey at the address shown below.

Survey at [phone], or visit its website at.www.nqs.noaa.go .

_SPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TO
INUNDATION BY THE 10, ANNUAL CHANCE FLOOD
The 1 % annual chance flood (100-year flood), also known as the base flood, is the flood
that has a 1 % chance of being equaled or exceeded in any given year_ The Special
Flood Hazard Area is the area subject to flooding by the 1 % annual chance flood. Areas
of Special Flood Hazard include Zones A, AE, AH, AO, AR, A99, V, and VE. The Base
Flood Elevation is the water surface elevation of the 1% annual chance flood.
ZONE A No Base Flood Elevations determined.
ZONE AE Base Flood Elevations determined.
ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood
Elevations determined.
ZONE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain);
average depths determined. For areas of alluvial fan flooding, velocities
also determined.
ZONE AR Special Flood Hazard Area formerly protected from the 1% annual
chance flood by a flood control system that was subsequently
decertified. Zone AR indicates that the former flood control system is
being restored to provide protection from the 1% annual chance or
greater flood.
ZONE A99 Area to be protected from 1 % annual chance flood by a Federal
flood protection system under construction; no Base Flood Elevations
determined.
ZONE VE Coastal flood zone with velocity hazard (wave action); Base Flood Elevations
determined.
® FLOODWAY AREAS IN ZONE AE
The floodway is the channel of a stream plus any adjacent floodplain areas that must be
kept free of encroachment so that the 1% annual chance flood can be carried without
substantial increases in flood heights.
OTHER FLOOD AREAS

Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface water and/or groundwater. The plant nutrients in the animal waste should be used
to reduce the amount of commercial fertilizer required for the crops in the fields where the waste
is to be applied.
This waste utilization plan uses nitrogen as the limiting nutrient. Waste should be analyzed
before each application cycle. Annual soil tests are strongly encouraged so that all plant
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.
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 11

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 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 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 2496.96 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 12484.8 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 41 acreas of land. If you apply the sludge
to corn at a rate of 125 pounds per acre, you will need 99.8784 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.

Additional Comments:
This plan revised to reflect the addition of a digester in field 2, updates the
production and application rates to match those listed on the NCSU Nutrient
Management website, and updates pivot acreages to reflect actual coverage
of the pivots. Some field boundaries were adjusted to reflect currnet conditions.
Fields Sub 1, Fld 2, Rd 3 and Sub 4 can be considered as optional fields as
long as the wetted acreages are in the crop rotation listed.
Any4l fields listed as "Optional Fields" are not required to be in any of the
crops listed in this plan unless they are actively being applied to or will be
applied to.

Owner: John Kilpatrick
Manager:
Owner/Manager Agreement:
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 DWR before the new
animals are stocked.
/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 NCDWR 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.
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 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.
4 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, NRCS 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
surface is frozen.
9 of 11

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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 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.
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 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.
12 Animal waste shall not be applied closer than 100 feet to wells.
13 Animal waste shall not be applied closer than 200 feet of dwellings other than those owned by
the landowner.
14 Waste shall be applied in a manner not to reach other property and public right-of-ways.
15 Animal waste shall not be discharged into surface waters, drainageways, or wetlands by discharge
or by over -spraying. Animal waste may be applied to prior converted cropland 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.
10 of 11

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
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 of 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 once every three
yeares at crop sites where waste products are applied. Nitrogen shall be the rate -determining
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.

Required Documentation
The following details of design and materials must accompany all irrigation designs:
1. A scale drawing of the proposed irrigation system which includes hydrant locations, pipelines, thrust block locations and buffer areas where applicable.
2. Assumptions and computations for determining total dynamic head and horsepower requirements.
3. Computations used to determine all mainline and lateral pipe sizes.
4. Sources and/or calculations used for determining application rates.
5. Computations used to determine the size of thrust blocks and illustrations of all thrust block configurations required in the system
6. Manufacturer's specifications for the irrigation pump, traveler and sprinkler(s).
7. Manufacturer's specifications for the irrigation pipe and/or USDA-NRCS standard for IRRIGATION WATER CONVEYANCE.
8. The information required by this form are the minimum requirements. It is the responsibility of the designer to consider all relevant factors at a particular site and
address them as appropriate.
9. Irrigation pipes should not be installed in lagoon or storage pond embankments without the approval of the designer.
NOTE: A buffer strip of 25' or wider must be maintained between the limits of the irrigation system and all
perennial streams and surface waters per NC Statutes.
NPDES permitting requires a vegetated buffer strip of 35' or wider be maintained between the limits of the irrigation system and all
perennial streams and surface waters per NC Statutes.

Sheet6
Narrative of Irrigation System Operation
This design dated 6/16/2020 is for a pivot addition and "wetted acreage" determination for an existing facility.
The acres were calculated based on the equipment specified and the charts created by NCSU for calculating
Area Allowances for Hard Hose Traveler Systems. The pivot acreages were computer calculated based on
manufacturers specifications.
This design shows the addition of a new pivot (#2), the removal of the solid set Zones 10, 11 & 12, the
removal of pulls 4, 6, 7 & 9, and the addition of pull 1 in place of Zone 12. An aerway will be used in place of
the removed pulls and zones. Field 11 (Zone 11) is no longer in the plan.
Refer to owner's manual and irrigation dealer for information on maintenance, winterization, and operation of
system.
Note: This design reflects setbacks for NPDES permitting (i.e. 35' vegetated ditch buffers).
This design revised 8/16/2024 to reflect the removal of Pull 1 due to the addition of a digester, and updating
the pivot acreages to reflect the actual coverage of the pivots. Some field borders were adjusted to reflect
current conditions.

ENVIRONMENTAL MANAGEMENT COMMISSION
DEPARTMENT OF ENVIRONMENTAL QUALITY
SWINE WASTE MANAGEMENT SYSTEM NPDES GENERAL PERMIT
This National Pollutant Discharge Elimination System (NPDES) General Permit (Permit) is issued pursuant to
North Carolina General Statutes G.S. 143-215 et seq. and Section 402 of the Clean Water Act (Act), may apply to
any swine facility in the State of North Carolina and shall be effective from July 1, 2017 until June 30, 2022. The
Division of Water Resources of the Department of Environmental Quality (Division) will make the facility's
Certificate of Coverage (COC) and Certified Animal Waste Management Plan (CAWMP) available for public
review for thirty (30) days prior to issuance of coverage under this Pennit.
The animal waste management systems covered by this Permit normally include some type of collection system
(flush, pit recharge, scraped lots, etc.); pipes or ditches for transmission of the waste; lagoons or ponds to collect,
treat, and store the waste; land application equipment; and sufficient acreage for application of the animal waste at
agronomic rates. If prior approval is received from the Director, this Permit may cover innovative treatment
systems incorporated into the animal waste management system.
All activities authorized herein shall be consistent with the terms and conditions of this Permit.
Holders of a COC under this Permit shall comply with the following specified conditions and limitations.
I. PERFORMANCE STANDARDS
Any discharge of waste that reaches surface waters or wetlands is prohibited except as otherwise
provided in this Permit and associated statutory and regulatory provisions. Waste shall not reach
surface waters or wetlands by runoff, drift, manmade conveyance, direct application, direct
discharge, or ditches not otherwise classified as state waters.
The waste management system operated under this Permit shall be effectively maintained and
operated as a non -discharge system to prevent the discharge of pollutants to surface waters or
wetlands. Application of waste to terraces and grassed waterways is acceptable as long as it is
applied in accordance with Natural Resources Conservation Service (MRCS) standards and does
not result in a discharge of waste to the surface waters or wetlands.
Facilities existing on or prior to April 14, 2003 must be designed, constructed, and operated to
contain all waste plus the accumulated volume from a 25-year, 24-hour rainfall event for the
location of the facility. A facility that has a discharge of waste that results because of a storm
event more severe than the 25-year, 24-hour storm will not be considered to be in violation of this
Pen -nit if the facility is in compliance with its CAWMP, the Act and its implementing regulations,
and this Permit.
Any discharge of waste that reaches surface waters or wetlands is prohibited from a facility
constructed after April 14, 2003 that is permitted for a Steady State Live Weight (SSLW)
equivalent to or greater than that of 10,000 swine each weighing less than 55 pounds or 2,500 or
more swine each weighing 55 pounds.
December 5, 2016

NPDES Permit Number NCA200000
Any discharge or application of waste to a ditch that drains to surface waters or wetlands is
prohibited except as follows: (a) discharges from the ditches are controlled by best management
practices (BMPs) designed in accordance with NRCS standards; (b) the BMPs have been
submitted to and approved by the Division; (c) the BMPs were implemented as designed to
prevent a discharge to surface waters or wetlands; (d) the waste was removed immediately from
the ditch upon discovery; and (e) the event was documented and reported in accordance with
Condition IV.21. of this Permit. Nothing in this exception shall excuse a discharge to surface
waters or wetlands except as may result because of rainfall from a storm event more severe than
the 25-year, 24-hour storm. [40 CFR 412 Subpart C and D; 15A NCAC 02T .1305 (e)]
2. No discharge of waste shall result in a violation of the water quality standards established for the
receiving waters as per Title 15A, Subchapter 213, Section .0200 of the North Carolina
Administrative Code (NCAC).
3. The facility's COC and its CAWMP are hereby incorporated by reference into this Permit. The
CAWMP must be consistent with all applicable laws, rules, ordinances, and standards (federal,
state and local) in effect at the time of siting and design and certification of the facility.
The Permittee must assess, on an ongoing basis, the effectiveness of the implementation of the
CAWMP. The Permittee must modify the CAWMP in order to address any changes needed to
maintain compliance with the facility's COC and this Permit. Any proposed change to the
CAWMP requires a formal request to modify the COC be submitted to the Division's Central
Office. The request shall include the proposed version of the CAWMP with changes from the
previous version identified. The Division will review the request to determine if the changes are
considered a major modification or a minor modification (see Section VIII. Definitions).
Proposed major modifications will be made available for public review and comment for thirty
(30) days. The Division will issue a new or amended COC after consideration of public
comments and approval of the modification. Note that a sludge removal and application plan is
considered a major modification of the CAWMP and is subject to the thirty (30) day public notice
requirement prior to approval. A facility may not implement a major modification until a new or
amended COC has been issued.
Minor modifications do not require public notice; however, the Permittee must receive approval
from the Division prior to implementation.
The Permittee may request permission from the Division to immediately proceed with a
temporary major modification to the CAWMP for a maximum of one hundred eighty (180) days.
The Division will make these modifications available for public review for thirty (30) days. The
public review must occur prior to the close of the temporary modification period. [40 CFR
122.42(e); 15A NCAC 02T .1305 (e)]
Any violation of the COC or the CAWMP shall be considered a violation of this Permit and
subject to enforcement actions. A violation of this Permit may result in the Permittee having to
take immediate or long-term corrective action(s) as required by the Division or the Environmental
Protection Agency (EPA). These actions may include, but are not limited to, modifying the
CAWMP; ceasing land application of waste; removing animals from the facility; or reopening
and modifying, revoking and reissuing, and/or terminating the COC. [40 CFR 122.41(a); 15A
NCAC 02T .1305 (e)]
4. Any proposed increase in the certified design capacity or the SSLW of animals above that
authorized by the COC will require a modification to the CAWMP and the COC prior to the
actual increase in either waste production or SSLW of animals.

this Pernut. [40 CFR 122.41 (d); 15A NCAC 02T .1305 (e)]
2. The Permittee shall, at all times, properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances), which are installed or used by the Permittee to
achieve compliance with the conditions of this Permit. Proper operation and maintenance
includes the operation of back-up or auxiliary facilities or similar systems only when necessary to
achieve compliance with the conditions of this Permit. [40 CFR 122.41(e); 15A NCAC 02T .1305
(e)]
The maximum waste level in lagoons/storage ponds shall not exceed that specified in the
facility's CAWMP. At a minimum, the maximum waste level for lagoons/storage ponds must not
exceed the level that provides adequate storage to contain a 25-year, 24-hour storm event plus the
designed structural freeboard [a minimum of one (1) foot is required] except that there shall be no
violation of this condition if:
there is a storm event more severe than a 25-year, 24-hour event,
the Permittee is in compliance with its CAWMP, and
the waste level has not entered the designed structural freeboard.
In addition to these requirements, new and expanding farms with lagoon/storage pond designs
completed after September 1, 1996 must also provide storage for the heavy rainfall factor. In
the case of gravity -fed lagoons/storage ponds in series, a 25-year, 24-hour storm event and/or the
heavy rainfall factor storage requirement for the system may be designed into the lowest
lagoon/storage pond in the system. However, adequate freeboard must be designed into the upper
lagoons/storage ponds to allow sufficient storage to prevent the waste level from rising into the
structural freeboard while the storm water is draining into the lowest lagoon in the system. [I 5A
NCAC 02T .1305 (b)]
4. A vegetative cover shall be maintained as specified in the facility's CAWMP on all land
application fields and buffers in accordance with the CAWMP. No waste shall be applied upon
areas not included in the CAWMP or upon areas where the crop is insufficient for nutrient
utilization. However, if the CAWMP allows, then waste may be applied up to thirty (30) days
prior to planting or breaking dormancy. [15A NCAC 02T .1305 (b)]
5. Soil pH on all land application fields must be adjusted according to the recommendation from the
Standard Soil Fertility Analysis (see Condition IV.7) to ensure that it is maintained in the
optimum range for crop production. [15A NCAC 02T. 1305 (b)]
6. Land application rates shall be in accordance with the CAWMP. In no case shall land application
rates for any field exceed agronomic rates or the established crop removal rate for phosphorus for
fields with a "HIGH" phosphorus -loss assessment rating as established using the Phosphorus
Loss Assessment Tool (PLAT) developed by NC State University and NRCS. There shall be no
waste application on fields with a "VERY HIGH" phosphorus -loss assessment rating.
In no case shall land application rates result in excessive ponding or any runoff during any given
application event. [ 15A NCAC 02T .1305 (b)]
December 5, 2016

NPDES Permit Number NCA200000
7. Direct application of animal waste onto land which is used to grow crops for direct human
consumption that do not undergo fiu-ther processing (e.g., strawberries, melons, lettuce, cabbage,
apples, etc.) shall not occur following the planting of the crop or at any time during the growing
season or, in the case of fruit bearing trees, following breaking dormancy. Application of animal
wastes shall not occur within thirty (30) days of the harvesting of fiber and food crops for direct
human consumption that undergoes further processing. [15A NCAC 02T .I 109(b)]
8. If manure or sludge is applied on conventionally tilled, bare soil, the waste shall be incorporated
into the soil within two (2) days after application on the land, or prior to the next rainfall event,
whichever occurs first. This requirement does not apply to no -till fields, pastures, or fields where
crops are actively growing. [15A NCAC 02T .1305 (b)]
The Permittee shall submit a sludge removal and application plan to the Division at least ninety
(90) days prior to sludge removal, as this is considered a major modification of the CAWMP (see
Condition I.3). A phosphorus -loss evaluation must be completed for any field that is to receive
sludge that has not already been evaluated in accordance with Condition IV.8, and the sludge land
application must be in accordance with the results of this evaluation. This condition does not
apply to situations where waste is transferred to, and land applied by a third party, as described in
Condition IV.10. [G. S. 143-215. I OC (e); 15A NCAC 02T. 1305 (b)]
The Permittee shall notify the appropriate Division Regional Office at least twenty-four (24)
hours prior to the start of sludge removal and land application. At the time of sludge removal
from a lagoon/storage pond, the sludge must be managed in accordance with the CAWMP.
When removal of sludge becomes necessary, provisions must be taken to prevent damage to the
lagoon/storage pond dikes and liner. [15A NCAC 02T .1305 (b)]
10. No material other than animal wastes of the type generated on this facility shall be disposed of in
the animal waste collection, treatment, storage, or land application systems. This includes but is
not limited to pesticides, toxic chemicals, and petroleum products. The Permittee shall comply
with effluent standards and prohibitions established under Section 307(a) of the Act for toxic
pollutants within the time provided in the regulations that establish these standards or
prohibitions, even if the Permit has not yet been modified to incorporate the requirement. [40
CFR 122.42 (e); 15A NCAC 02T . 13 05 (b)]
11. Domestic and/or industrial wastewater from showers, toilets, sinks, etc. shall not be discharged
into the animal waste management system. Wash water from the cleaning of stock trailers will be
permissible only for trailers that are owned by the facility and are used to transport animals to and
from the facility, as long as the system has been evaluated and approved to accommodate the
additional volume. Only those cleaning agents and soaps that are EPA approved, will not harm
the' cover crop, and will not contravene the groundwater standards listed in 15A NCAC 2L may
be utilized in facilities covered by this Permit. Instruction labels are to be followed when using
cleaning agents and soaps. [15A NCAC 02T . 13 05 (b)]
12. Disposal of dead animals resulting from normal mortality rates associated with the facility shall
be done in accordance with the facility's CAWMP and the North Carolina Department of
Agriculture and Consumer Services (NCDA&CS) Veterinary Division's statutes and regulations.
As a part of the facility's CAWMP, the Permittee shall develop a mortality management plan that
addresses normal mortality rates and mass mortality scenarios.
December 5, 2016

Required Documentation
The following details of design and materials must accompany all irrigation designs:
1. A scale drawing of the proposed irrigation system which includes hydrant locations, pipelines, thrust block locations and buffer areas where applicable.
2. Assumptions and computations for determining total dynamic head and horsepower requirements.
3. Computations used to determine all mainline and lateral pipe sizes.
4. Sources and/or calculations used for determining application rates.
5. Computations used to determine the size of thrust blocks and illustrations of all thrust block configurations required in the system
6. Manufacturer's specifications for the irrigation pump, traveler and sprinkler(s).
7. Manufacturer's specifications for the irrigation pipe and/or USDA-NRCS standard for IRRIGATION WATER CONVEYANCE.
8. The information required by this form are the minimum requirements. It is the responsibility of the designer to consider all relevant factors at a particular site and
address them as appropriate.
9. Irrigation pipes should not be installed in lagoon or storage pond embankments without the approval of the designer.
NOTE: A buffer strip of 25' or wider must be maintained between the limits of the irrigation system and all
perennial streams and surface waters per NC Statutes.
NPDES permitting requires a vegetated buffer strip of 35' or wider be maintained between the limits of the irrigation system and all
perennial streams and surface waters per NC Statutes.

Sheet6
Narrative of Irrigation System Operation
This design dated 6/16/2020 is for a pivot addition and "wetted acreage" determination for an existing facility.
The acres were calculated based on the equipment specified and the charts created by NCSU for calculating
Area Allowances for Hard Hose Traveler Systems. The pivot acreages were computer calculated based on
manufacturers specifications.
This design shows the addition of a new pivot (#2), the removal of the solid set Zones 10, 11 & 12, the
removal of pulls 4, 6, 7 & 9, and the addition of pull 1 in place of Zone 12. An aerway will be used in place of
the removed pulls and zones. Field 11 (Zone 11) is no longer in the plan.
Refer to owner's manual and irrigation dealer for information on maintenance, winterization, and operation of
system.
Note: This design reflects setbacks for NPDES permitting (i.e. 35' vegetated ditch buffers)

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 DWR 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.

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 speck 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 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 time to interplant small grain, etc, is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

Acres shown in the preceding table are considered to be the usable acres excluding
required buffers, filter strips along ditches, odd areas unable to be irrigated, and perimeter areas
not receiving full application rates due to equipment limitations. Actual total acres in the fields
listed may, and most likely will be, more than the acres shown in the tables.

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 2496.96 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 12484.8 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 41 acreas of land. If you apply the sludge
to com at a rate of 125 pounds per acre, you will need 99.8784 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.

Soil Investigation to Determine Suitability of Proposed Lagoon Site
-------------------------------------
Page 1
A total of three (3) soil borings were taken on this site by Johnny Lanier, SCS, to
determine if the existing soils would be suitable for embankment material for the lagoon.
All of the borings were made in the vicinity of the proposed lagoon.
The benchmark elevation of 50.00 feet is located on the top of 3/4" rebar, 20' SW of C,0+00.
The estimated high water table elevation = 48.5 Feet, +/—
Using the Unified Classification System, the results of the borings are as follows:
Boring #1: F, 6+80; Elev. = 50.5 feet
0 Ft. — 2 Ft. — SM material (silty sand)
2 Ft. — 4 Ft. — SM,SC materials (silty sands; clayey sands)
4 Ft. — 7 Ft. — SC material (clayey sands; sand —clay mixtures)
7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays)
Boring #2: F, 5+00; Elev. = 50.6 feet
0 Ft. — 2 Ft. — SM material (silty sand)
2 Ft. — 5 Ft. — SC material (clayey sands; sand —clay mixtures)
5 Ft. — 7 Ft. — SM material (silty sand)
7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays)
Boring #3: 13+50, 5+50; Elev. = 47.1 feet
0 Ft. — 1 Ft. — SM material (silty sand)
1 Ft. — 3 Ft. — SC material (clayey sands; sand —clay mixtures)
3 Ft. — 5 Ft. — SM,SC materials (silty sands; clayey sands)
5 Ft. — 7 Ft. — SC,SM materials (clayey sands; silty sands)
7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays)
Based on the results of these borings, some of the soils available on this site are suitable
to be used as embankment material for the lagoon site. A suitable clay material (SC,CL,etc.)
for the liner will be required.

OPERATION AND MAINTENANCE PLAN
This lagoon is designed for waste treatment (permanent storage) with minimum
odor control. The time required for the planned fluid level to be reached
(permanent + temporary storage) may vary due to soil conditions, flushing
operations, and the amount of fresh water added to the system.
The designed 6 months temporary storage is an estimated volume based on:
1) waste from animals
2) excess rainfall after evaporation
and 3) the largest 24 hour (one day) rainfall that occurs on the average
of once every 25 years.
The volume of waste generated from a given number of animals will be fairly
constant throughout the year and from year to year.
This estimate is based on 7.0 inches of excess rainfall which is equal
to or exceeds the highest 6 months excess in a year. The average annual excess
rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess
rainfall will need to be pumped each year. The 25 year rainfall will not be a
factor to consider in an annual pumping cycle, but this storage volume must
always be available. A maximum elevation is determined in each design to begin
pumping and this is usually the outlet invert of pipe(s) from the building(s).
If the outlet pipe is not installed on the elevation to begin pumping, a
permanent marker must be installed on this elevation to indicate when pumping
should begin. An elevation must be established to stop pumping to maintain the
minimum treatment depth of 6 feet.
Pumping can be started or stopped at any time between these two elevations
for operating convenience as site conditions permit, such as weather, soils,
crop, and equipment in order to apply waste without runoff or leaching.
Land application of waste water is recognized as an acceptable method of
disposal. Methods of application include solid set, center pivot guns and
traveling gun irrigation. Care should be taken when applying waste to
prevent damage to crops.

OPERATION AND MAINTENANCE PLAN (continued)
-----------------------
The following items are to be carried out:
Page 2
1. It is strongly recommended that the treatment lagoon be precharged to 1/2
of its capacity to prevent excessive odors during start—up. Precharging
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 pump —out of the lagoon when fluid level reaches elevation 0.feet
as marked by the permanent marker.
66pump-out of the lagoon when fluid level reaches elevation 30 feet
or before the fluid depth is less than &Wt feet deep (this prevents
the loss of favorable bacteria).
The designed temporary storage volume less the 25 year — 24 hour
storm volume is 175,168 cubic feet or 1,310,259 gallons.
As stated before, this volume will vary considerably from year to year.
4. The recommended maximum amount to apply per irrigation is one (1) inch
and the recommended maximum application rate is 0.3 inches per hour.
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.
6. Repair any eroded areas or areas damaged by rodents and establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable outlets.
8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization
fields adjacent to perennial streams. Waste will not be applied in open ditches.
Do not pump within 200 feet of a residence or within 100 feet of a well.
9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters
of the United States. The Department of Environment, Health and Natural
Resources, Division of Environmental Management, has the responsibility
for enforcing this law.

SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS
------------------------------------------
SECTION 1: CLEARING
All trees and brush shall be removed from the construction area before any
excavation or fill is started. Stumps will be removed within the area of the
foundation of the embankment, all fill areas and all excavated areas. All
All stumps and roots exceeding one (1) inch in diameter shall be removed
to a minimum depth of one (1) foot below final grade. Satisfactory disposition
will be made of all debris.
The foundation area shall be loosened thoroughly before placement of
the embankment material. The lagoon site (and pad site if needed) is to be
stripped of topsoil (minimum of 3") and stockpiled for use on dike and pad
slopes (finished depth of 2-3").
SECTION 2: CUT—OFF TRENCH
A cut—off trench (when specified) shall be installed as shown on the plans.
SECTION 3: 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 be placed in a maximum of 6" lifts and shall not
be placed in standing water. Compaction shall be performed by the construction
equipment or by a 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 overage
for settlement.

SPECIFICATIONS FOR CONSTRUCTION (Continued)
-----------------------------
To protect against seepage, when areas of unsuitable material are
encountered, they will need to be excavated to a minimum of one (1) foot
below grade and backfilled and compacted with a SCS approved material
(ie — CL, SC, CH). Refer to the soil investigation information in the plans
for special considerations. Precautions should be taken during construction
to prevent excessive erosion and sedimentation.
SECTION 4: VEGETATION
All exposed embankment and other bare constructed areas shall be seeded
to the planned type of vegetation as soon as possible after construction
according to seeding specifications sheet.

Soil Investigation to Determine Suitability of Proposed Lagoon Site
-------------------------------------
Page 1
A total of three (3) soil borings were taken on this site by Johnny Lanier, SCS, to
determine if the existing soils would be suitable for embankment material for the lagoon.
All of the borings were made in the vicinity of the proposed lagoon.
The benchmark elevation of 50.00 feet is located on the top of 3/4" rebar, 20' SW of C,0+00.
The estimated high water table elevation = 48.5 Feet, +/—
Using the Unified Classification System, the results of the borings are as follows:

0 Ft. — 2 Ft. — SM material (silty sand)
2 Ft. — 5 Ft. — SC material (clayey sands; sand —clay mixtures)
5 Ft. — 7 Ft. — SM material (silty sand)
7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays)
Boring #3: B+50, 5+50; Elev. = 47.1 feet
0 Ft. — 1 Ft. — SM material (silty sand)
1 Ft. — 3 Ft. — SC material (clayey sands; sand —clay mixtures)

5 Ft. — 7 Ft. — SC,SM materials (clayey sands; silty sands)
7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays)
Based on the results of these borings, some of the soils available on this site are suitable
to be used as embankment material for the lagoon site. A suitable clay material (SC,CL,etc.)
for the liner will be required.

OPERATION AND MAINTENANCE PLAN
-----------------------
This lagoon is designed for waste treatment (permanent storage) with minimum
odor control. The time required for the planned fluid level to be reached
(permanent + temporary storage) may vary due to soil conditions, flushin
operations, and the amount of fresh water added to the system. g
The designed 6 months temporary storage is an estimated volume based on:
1) waste from animals
2) excess rainfall after evaporation
and 3) the largest 24 hour (one day) rainfall that occurs on the average
of once every 25 years.
The volume of waste generated from a given number of animals will be fairly
constant throughout the year and from year to year.
This estimate is based on 7.0 inches of excess rainfall which is equal
to or exceeds the highest 6 months excess in a year. The average annual excess
rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess
rainfall will need to be pumped each year. The 25 year rainfall will not be a
factor to consider in an annual pumping cycle, but this storage volume must
always be available. A maximum elevation is determined in each design to begin
pumping and this is usually the outlet invert of pipe(s) from the building(s).
If the outlet pipe is not installed on the elevation to begin pumping, a
permanent marker must be installed on this elevation to indicate when pumping
should begin. An elevation must be established to stop pumping to maintain the
minimum treatment depth of 6 feet.
Pumping can be started or stopped at any time between these two elevations
for operating convenience as site conditions permit, such as weather, soils,
crop, and equipment in order to apply waste without runoff or leaching.
Land application of waste water is recognized as an acceptable method of
disposal. Methods of application include solid set, center pivot guns and
traveling gun irrigation. Care should be taken when applying waste to
prevent damage to crops.

OPERATION AND MAINTENANCE PLAN (continued)
-----------------------
The following items are to be carried out:
Page 2
It is strongly recommended that the treatment lagoon be precharged to 1/2
of its capacity to prevent excessive odors during start—up. Precharging
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. gin pump —out of the lagoon when fluid level reaches elevation afeet
as marked by the permanent marker.
p pump -out of the lagoon when fluid level reaches elevation T 30 feet
or before the fluid depth is less than SM"' feet deep (this prevents
the loss of favorable bacteria).
The designed temporary storage volume less the 25 year — 24 hour
storm volume is 175,168 cubic feet or 1,310,259 gallons.
As stated before, this volume will vary considerably from year to year.
4. The recommended maximum amount to apply per irrigation is one (1) inch
and the recommended maximum application rate is 0.3 inches per hour.
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.
6. Repair any eroded areas or areas damaged by rodents and establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable outlets.
8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization
fields adjacent to perennial streams. Waste will not be applied in open ditches.
Do not pump within 200 feet of a residence or within 100 feet of a well.
9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters
of the United States. The Department of Environment, Health and Natural
Resources, Division of Environmental Management, has the responsibility
for enforcing this law.

SECTION 1: CLEARING
All trees and brush shall be removed from the construction area before any
excavation or fill is started. Stumps will be removed within the area of the
foundation of the embankment, all fill areas and all excavated areas. All
All stumps and roots exceeding one (1) inch in diameter shall be removed
to a minimum depth of one (1) foot below final grade. Satisfactory disposition
will be made of all debris.
The foundation area shall be loosened thoroughly before placement of
the embankment material. The lagoon site (and pad site if needed) is to be
stripped of topsoil (minimum of 3") and stockpiled for use on dike and pad
slopes (finished depth of 2-3").
SECTION 2: CUT—OFF TRENCH
A cut—off trench (when specified) shall be installed as shown on the plans.
SECTION 3: 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 be placed in a maximum of 6" lifts and shall not
be placed in standing water. Compaction shall be performed by the construction

INSTRUCTIONS
All dams built with technical assistance from the Soil Conservation Service
must have a hazard classification assigned by the person responsible for
approving the design. Most farm ponds, except in borderline cases, can
be classified after a complete field investigation without assuming failure
and making breach studies. This data sheet is to be used for recording
the information obtained through field studies and for documenting the
hazard classification. Where there is a possibility for loss of life or
major property damage from a dam failure, an approved breach routing
procedure is to be used. (Consult with the area engineer.)
Hazard classifications of dams are made by evaluating the possibility
for loss of life and the extent of damage that would result if the dam
should suddenly breach --that is --a section of the dam be suddenly and
completely washed out. It is to be assumed that a wall of water will be
released equal to the height of the dam. This flood wave will be reduced
in height as it moves down the flood plain. The wave height (depth of
flooding) should be evaluated for a sufficient distance downstream until
the estimated flood level will not cause significant damage to improvements,
such as homes, buildings, roads, utilities, reservoirs, etc. The breach
flood level will be reduced depending on the valley storage, slope, and
openess of the flood plain; however, in a narrow steep valley slopes
steeper than 10% should be given special consideration. One method of
evaluation is to compare available valley storage (under flood conditions)
to impoundment storage (figured to the top of the dam) for each reach
evaluated with a judgment estimate made of the flood wave height at all
critical points downstream.
Should there be any questions about the hazard classification for a dam,
the area engineer should be consulted';',befdre making design commitments.

Soil Investigation to Determine Suitability of Proposed Lagoon Site
-------------------------------------
Page 1
A total of three (3) soil borings were taken on this site by Johnny Lanier, SCS, to
determine if the existing soils would be suitable for embankment material for the lagoon.
All of the borings were made in the vicinity of the proposed lagoon.
The benchmark elevation of 50.00 feet is located on the top of 3/4" rebar, 20' SW of C,0+00.
The estimated high water table elevation = 48.5 Feet, +/—
Using the Unified Classification System, the results of the borings are as follows:
Boring #1: F, 6+80; Elev. = 50.5 feet
0 Ft. — 2 Ft. — SM material (silty sand)
2 Ft. — 4 Ft. — SM,SC materials (silty sands; clayey sands)
4 Ft. — 7 Ft. — SC material (clayey sands; sand —clay mixtures)
7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays)
Boring #2: F, 5+00; Elev. = 50.6 feet
0 Ft. — 2 Ft. — SM material (silty sand)
2 Ft. — 5 Ft. — SC material (clayey sands; sand —clay mixtures)
5 Ft. — 7 Ft. — SM material (silty sand)

OPERATION AND MAINTENANCE PLAN
This lagoon is designed for waste treatment (permanent storage) with minimum
odor control. The time required for the planned fluid level to be reached
(permanent + temporary storage) may vary due to soil conditions, flushing
operations, and the amount of fresh water added to the system.
The designed 6 months temporary storage is an estimated volume based on:
1) waste from animals
2) excess rainfall after evaporation
and 3) the largest 24 hour (one day) rainfall that occurs on the average
of once every 25 years.
The volume of waste generated from a given number of animals will be fairly
constant throughout the year and from year to year.
Page 1
This estimate is based on 7.0 inches of excess rainfall which is equal
to or exceeds the highest 6 months excess in a year. The average annual excess
rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess
rainfall will need to be pumped each year. The 25 year rainfall will not be a
factor to consider in an annual pumping cycle, but this storage volume must
always be available. A maximum elevation is determined in each design to begin
pumping and this is usually the outlet invert of pipe(s) from the building(s).
If the outlet pipe is not installed on the elevation to begin pumping, a
permanent marker must be installed on this elevation to indicate when pumping
should begin. An elevation must be established to stop pumping to maintain the
minimum treatment depth of 6 feet.
Pumping can be started or stopped at any time between these two elevations
for operating convenience as site conditions permit, such as weather, soils,
crop, and equipment in order to apply waste without runoff or leaching.
Land application of waste water is recognized as an acceptable method of
disposal. Methods of application include solid set, center pivot guns and
traveling gun irrigation. Care should be taken when applying waste to
prevent damage to crops.

OPERATION AND MAINTENANCE PLAN (continued)
-----------------------
The following items are to be carried out:
It is strongly recommended that the treatment lagoon be precharged to 1 /2
of its capacity to prevent excessive odors during start—up. Precharging
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 pump —out of the lagoon when fluid level reaches elevation 51.50 feet
as marked by the permanent marker.
Stop pump —out of the lagoon when fluid level reaches elevation 49.30 feet
or before the fluid depth is less than 7.80 feet deep (this prevents
the loss of favorable bacteria).
The designed temporary storage volume less the 25 year — 24 hour
storm volume is 175,168 cubic feet or 1,310,259 gallons.
As stated before, this volume will vary considerably from year to year.
4. The recommended maximum amount to apply per irrigation is one (1) inch
and the recommended maximum application rate is 0.3 inches per hour.
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.
6. Repair any eroded areas or areas damaged by rodents and establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable outlets.
8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization
fields adjacent to perennial streams. Waste will not be applied in open ditches.
Do not pump within 200 feet of a residence or within 100 feet of a well.
9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters
of the United States. The Department of Environment, Health and Natural
Resources, Division of Environmental Management, has the responsibility
for enforcing this law.

This plan will be implemented in the event that wastes from your operation are leaking,
overflowing or running off 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
responses to some possible problems are listed below.
A. Lagoon overflow - possible solutions are:
a) Add soil to berm to increase elevation of dam.
b) Pump wastes to fields at an acceptable rate
c) Stop all flow to the lagoon immediately.
d) Call a pumping contractor.
e) Make sure no surface water is entering lagoon.
B. Runoff from waste application field -actions include:
a) Immediately stop waste application.
b) Create a temporary diversion to contain waste.
c) Incorporate waste to reduce runoff
d) Evaluate and eliminate the reason(s) that cause the runoff.
e) Evaluate the application rates for the fields where runoff occurred.
C. Leakage from the waste pipes and sprinklers - action include:
a) Stop recycle pump.
b) Stop irrigation pump.
c) Close valves to eliminate further discharge.
d) Repair all leaks prior to restarting pumps.
D. Leakage from flush systems, houses, solid separators - action include:
a) Stop recycle pump.
b) Stop irrigation pump.
c) Make sure siphon occurs.
d) Stop all flow in the house, flush systems, or solid separators.
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 from the embankment to catch all seepage, put in a submersible
pump, and pump back to 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 side walls 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 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?
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 the property)?
h. How much reached surface waters?
3. Contact appropriate agencies.
a. During normal business hours call your DWQ regional office; Phone *, After hours,
emergency number: [phone]. Your phone call should include: your name, facility
number, telephone number, the details of the incident from item 2 above, the exact
location of the facility, the location or direction of the movement of the spill, weather and
wind conditions. The corrective measures that have been under taken, and the
seriousness of the situation.
b. If the spill leaves property or enters surface waters, call local EMS phone number.
c. Instruct EMS to contact local Health Department.
d. Contact CE's phone number, local SWCD office phone number and the local NRCS
office for advice / technical assistance phone number.
4. If none of the above works call 911 or the Sheriffs Department and explain your problem to
them and ask the person to contact the proper agencies for you.
5. Contact the contractor of your choice to begin repair or problem to minimize offsite damage.
a. Contractors Name: Murphy Brown, LLC
b. Contractors Address: P.O. Box 856, Warsaw NC 28398
c . Contractors Phone: [phone]
6. Contact the technical specialist who certified the lagoon (NRCS, Consulting Engineer, etc.)
a. Name: Kraig Westerbeek
b. Phone: (910) 293 - 5330
Implement procedures as advised by DWQ 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.
