Subject: Carter & Sons Hog Farm 1&2
Facility # AWS310160
State Digester General Permit
Dear Ms. Lawson,
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 Carter & Sons Hog Farm 1&2. 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 with the
exception of the 500 ft. property line setback. The farm owner has obtained a signed waiver from David Wallace and John
Kilpatrick as the digester is withing 500' of their respective property lines. The digester is beyond 2500 ft. from any public
building 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 51,700 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 the signed setback waivers from David Wallace & John Kilpatrick
7. One (1) copy of the 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.
Page 1 of 2

Please note that the Surface Water Classification (Section 7 of the application) has been submitted to the appropriate regional
DWR office (or will be in the near future), and we expect to forward that approval to you in the next few weeks.
Please do not hesitate to contact me or my office if you have any questions, comments or require any additional information.
Thank you,

To Whom it May Concern:
This letter of acknowledgement and agreement is hereby given to the Carter and Sons Farm as it
relates to their installation of a farm digester.
I have been informed of the desire of the Carter and Sons Farm to add a digester to their farm,
increasing the treatment of manure on the farm and capturing the emissions from the breakdown of the
manure for use as a renewable fuel. I understand that this will reduce emissions from the farm, and that
no more animals will be added to the site or current waste treatment system.
I hereby approve the digester structure being closer to my property line than the existing lagoon
on the farm by approximately 275'. This waiver applies to parcel PIN number 341100977627 of the
Duplin County tax office.

*Note: Roeslein Digesters are designed regarding Hydraulic Retention Time, not NCDEQ Minimum Treatment Volume for hog farms
*Note: New digester is NOT providing additional treatment storage capacity in accordance with NCDEQ standards (135 cuft/lb*lb/hog), but instead serves as a
steady-state reservoir, diverting additional water volume to existing treatment lagoons for storage and land application.

Note: Both Rainfall values set to 0 because no rainfall will enter the sealed digester. Excess will be pumped off of cover.
Note: Per Conservation Practice Standard Waste Treatment Lagoon (Code 359) "General Criteria for All Lagoons", the digester storage volume does

r Narrative 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 at Carter & Sons 1 will be directed through a 12-inch
diameter gravity pipe header directly to the digester.
Upon flushing, the wastewater from the barns at Carter & Sons 2 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 Carter & Sons 2 will be 10 HP GEA pump, designed for a flow of 430
gallons/minute, through 6-inch diameter, HDPE SDR 17 force -main into the new anaerobic lagoon
digester.
The approximate dimensions of the new anaerobic lagoon digester are 360 feet by 180 feet with a total
volume of 565,056 cubic feet and a treatment capacity of 441,840 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 of the digester, 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 weir (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 lagoons through a 6-inch diameter
pipe. Valve station at transfer pump will determine which lagoon will get transfer water.
The transfer pump will be 15 HP GEA pump, designed for a flow of 636 gallons/minute, through 6-inch
diameter, HDPE SDR 17 force -main and valve station to each existing lagoon.
Water will be transferred back to existing lagoon 27502 by floating transfer pump in existing lagoon
27501B. The transfer pump to lagoon 27502 will be 10 HP GEA pump, designed for a flow of 488
gallons/minute, through 6-inch diameter, HDPE SDR 17 force -main.

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.

Anaerobic Digester O&M
Revision: 0
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.

Effective Date: 4/15/2024
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
o Safety glasses, safety shoes, gloves.
o Personal Floatation Devices — when working on the cover.

OF 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.
a -GM nu,ydbe Biogas contains primarily methane (55 — 60%), and carbon dioxide (35 —
40%). However, biogas also contains hazardous trace amounts of hydrogen
sulfide (H2S), nitrogen (< 2%), oxygen (< 1%), and water vapor (<8%).
Hydrogen Sulfide (H2S) has a distinct "rotten egg" odor at low concentrations.
e
However, at higher concentrations, it overwhelms the sense of smell and
cannot be detected. At concentrations > 1000 ppm, it can cause immediate lsk> unconsciousness and death through respiratory paralysis.

Hydrogen Sulfide compositions in the biogas feed supply can be at 1500 to
2500 ppm/vol, however the tail gas/permeate from the membrane routing to
the thermal oxidizer can be in the 10,000 ppm/vol range.
Carbon Dioxide (CO2) is a colorless, odorless, tasteless, non -irritating, non-
4 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.

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
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

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
LIQUID
MANURE

ALMEME
DE ESTIEROL
OQUI
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
employees and visitors to the AD facility should be cautioned not to touch any equipment or
pipelines.
Figure 3: Permanent ladder and
guardrail on feedstock storage tank
When possible, hot surfaces should be identified as burn hazards, and all pipes should be
clearly labeled to indicate the contents,

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
digester) and digestate (any material exiting
the digester) should be carefully transferred M, I
and contained. In the event of a major 1 T t
feedstock or digestate spill, workers should
h
exercise caution when containing the
material. The first step should be to control I
j
the source causing the spill. Once this is
achieved, workers should contain the spill by
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
Ima�¢s from Goode 4r+a�es
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:
1. 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
are referred to as asphyxiants. There are two categories of
Figure 13: Self-contained
breathing apparatus
f
1:, lk_.. 1, -t -
Imam kamtMVV.j4rwrr.eMlaappy.c*nV
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.

LFT. 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.
{ �� ■ s }. }" 2.4.2 Low voltage
All electrical sources less than 600 volts are considered
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
U
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 ;he 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. Surrey 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 881. 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 olevations 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.

This digital Flood Insurance Rate Map (FIRM) was produced through a unique:
cooperative partnership between the State of North Carolina and the Fedora
Emergency Management Agency (FEMA). The State of North Carolina ha::
implemented a long term approach of floodplain management to decrease
the costs associated with flooding. This is demonstrated by the State's com-
mitment to map floodplain areas at the local level. As a Par' f this effort. . the
State of North Carolina hasjoined in a Cooperating TtichnicaIState agreement
with FEMA to produce and maintain this digital FIRM.

Narrative
8/15/2024 - This plan has been updated to remove the area that will be used for the digester. With the
removal of this location (pull 12) from the farm Nutrient Management Plan this farm still has sufficient
remaining pumping wettable acres. All crops have been changed to Bermuda Pasture/Small Grain
Overseed. This plan will replace last plan dated 12/26/2016 when the new digester permit has been
received. Grower also has the option bale the bermuda as he desires. All pumping areas that are baled
may use the Bermuda Hay rate of the following: p 1-2, p4-6, p 11, p 13-15, and Sub 1-5 (194 Ibs/ac), p3
(240 Ibs/ac), and p16 (293 lbs/ac).

The Waste Utilization table shown below summarizes the waste utilization plan for this operation. This plan provides an estimate of the number of acres of
cropland needed to use the nutrients being produced. The plan requires consideration of the realistic yields of the crops to be grown, their nutrient requirements,
and proper timing of applications to maximize nutrient uptake.
This table provides an estimate of the amount of nitrogen required by the crop being grown and an estimate of the nitrogen amount being supplied by manure or
other by-products, commercial fertilizer and residual from previous crops. An estimate of the quantity of solid and liquid waste that will be applied on each field in
order to supply the indicated quantity of nitrogen from each source is also included. A balance of the total manure produced and the total manure applied is
included in the table to ensure that the plan adequately provides for the utilization of the manure generated by the operation.

The Irrigation Application Factors for each field in this plan are shown in the following table. Infiltration rate varies
with soils. If applying waste nutrients through an irrigation system, you must apply at a rate that will not result in
runoff. This table provides the maximum application rate per hour that may be applied to each field selected to
receive wastewater. It also lists the maximum application amount that each field may receive in any one application
event.

NOTE: Symbol' means user entered data.

The following Lagoon Sludge Nitrogen Utilization table provides an estimate of the number of acres needed for
sludge utilization for the indicated accumulation period. These estimates are based on average nitrogen
concentrations for each source, the number of animals in the facility and the plant available nitrogen application
rates shown in the second column.
Lagoon sludge contains nutrients and organic matter remaining after treatment and application of the effluent. At
clean out, this material must be utilized for crop production and applied at agronomic rates. In most cases, the
priority nutrient is nitrogen but other nutrients including phosphorous, copper and zinc can also be limiting. Since
nutrient levels are generally very high, application of sludge must be carefully applied.
Sites must first be evaluated for their suitability for sludge application. Ideally, effluent spray fields should not be
used for sludge application. If this is not possible, care should be taken not to load effluent application fields with
high amounts of copper and zinc so that additional effluent cannot be applied. On sites vulnerable to surface water
moving to streams and lakes, phosphorous is a concern. Soils containing very high phosphorous levels may also
be a concern.

The Available Waste Storage Capacity table provides an estimate of the number of days of storage
capacity available at the end of each month of the plan. Available storage capacity is calculated as the
design storage capacity in days minus the number of days of net storage volume accumulated. The start
date is a value entered by the user and is defined as the date prior to applying nutrients to the first crop in
the plan at which storage volume in the lagoon or holding pond is equal to zero.
Available storage capacity should be greater than or equal to zero and less than or equal to the design
storage capacity of the facility. If the available storage capacity is greater than the design storage
capacity, this indicates that the plan calls for the application of nutrients that have not yet accumulated.
If available storage capacity is negative, the estimated volume of accumulated waste exceeds the design
storage volume of the structure. Either of these situations indicates that the planned application interval
in the waste utilization plan is inconsistent with the structure's temporary storage capacity.

Required Specifications For Animal Waste Management
1. Animal waste shall not reach surface waters of the state by runoff, drift,
manmade conveyances, direct application, or direct discharge during
operation or land application. Any discharge of waste that 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 Management Plan when there is a change in the
operation, increase in the number of animals, method of application,
receiving 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, MRCS Field
Office Technical Guide Standard 393 - Filter Strips).
5. Odors can be reduced by injecting the waste or by 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).
306306 Database Version 4.1 Date Printed: 8/15/2024 Specification Page 1

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 soil surface is frozen.
9. Animal waste shall be applied on actively growing crops in such a manner
that the crop is not covered with waste to a depth that would inhibit
growth. The potential for salt damage from animal waste should also be
considered.
10. 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 that 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.
306306 Database Version 4.1 Date Printed: 8/15/2024 Specification Page 2

15. Animal waste shall not be discharged into surface waters, drainageways,
or wetlands by a 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.
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.
306306 Database Version 4.1 Date Printed: 8/15/2024 Specification Page 3

22. Waste shall be tested within 60 days of utilization and soil shall be tested
at least annually at crop sites where waste products are applied. Nitrogen
shall be the rate -determining 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
soils 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 five
(5) years.
23. Dead animals will be disposed of in a manner that meets North Carolina
regulations.

Bermudagrass CP, Mineral Soil, Poorly Drained to Somewhat Poorly Drained.
Adaptation: Effective artificial drainage MUST be in place to achieve Realistic Yield Expectations
provided for these soils.
In the Coastal Plain, hybrid bermudagrass sprigs can be planted Mar. I to Mar. 31. Cover sprigs 1" to 3"
deep (1.5" optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and
wind. For Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a
rate of 30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing
conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced V to 1.5' in row.
For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime, phosphorus,
potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 100 Ib/ac N in
the establishment year in split applications in April and July. For established stands apply 180 to 240
Ib/ac N annually in split applications, usually in April and following the first and second hay cuts.
Reduce N rates by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization
of Pastures and Forages in North Carolina for more information or consult your regional agronomist or
extension agent for assistance.

1. A scale drawing of the proposed irrigation system which includes hydrant locations, pipelines, thrust b€nck locations and buffer areas where appOcable.
2. Assumptions and computations for determining total dynamlc head and horsepower requirements.
3: Computations used to determine all mainline and lateral pipe sixes.
4. Sources and/or cautions used for determining application rates.
5. Computations used to determine the size of thrust blocks and lliustratfnns of all thrust block con€fgumtions required In the system
B. 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
& The information required by this form are the rninimum requirements. It Is the respossibli€ty of the designer to consider all relevant factors at a particular site and
address them as appropriate.
8. Irrigation Pies show not be Installed in lagoon or storage pond embankments without the approval of the designer.
NOTE: A buffer strip of W or wider rust be malr rained between the bits of the irrigation system and all
perennial streams and surface waters per NO Statutes.

Narrative of Irrigation System Operation

The V Jb Utilization table shown below summarizes the waste utilization k. for this operation. This plan provides an estimate of the number �.facres of
cropland needed to use the nutrients being produced. The plan requires consideration of the realistic yields of the crops to be grown, their nutrient requirements;
and proper tuning of applications to maximize nutrient uptake.
This table provides an estimate of the amount of nitrogen required by the crop being grown and an estimate of the nitrogen amount being supplied by manure or
other by-products, commercial fertilizer and residual from previous crops. An estimate ofthe quantity of solid and liquid waste that will be applied on each field in
order to supply the indicated quantity of nitrogen from each source is also included. A balance of the total manure produced and the total manure applied is
included in the table to ensure that the plan adequately provides for the utilization of the manure generated by the operation.

The following Lagoon Sludge Nitrogen Utilization table provides an estimate ofthe number of acres needed for
sludge utilization for the indicated accumulation period. These estimates are based on average nitrogen
concentrations for each source, the number ofanimals in the facility and the plant available nitrogen application
rates shown in the second column.
Lagoon sludge contains nutrients and organic matter remaining after treatment and application ofthe effluent. At
clean out, this material must be utilized for crap production and applied at agronomic rates. fn most cases, the
priority nutrient is nitrogen but other nutrients including phosphorous, copper and zinc can also be limiting. Since
nutrient levels are generally very high, application ofsludge .must be carefully applied.
Sites must first be evaluated for their suitability for sludge application. ideally, effluent spray fields should not be
used for sludge application. Wthis is not possible, care should betaken not to load effluent application fields with
high amounts of capper and zinc so that additional effluent cannot be applied. On sites vulnerable to surface water
moving to streams and lakes, phosphorous is a concern. Sails containing very high phosphorous levels may also
be a concern.

The Available Waste Storage Capacity table provides an estimate of the number of days of storage
capacity available at the end of each month of the plan. Available storage capacity is calculated as the
design storage capacity in days minus the number of days of net storage volume accumulated. The start
date is a value entered by the user and is definers as the date prior to applying nutrients to the first crop in
the plan at which storage volume in the lagoon or holding pond is equal to zero.
Available storage capacity should be greater than or equal to zero and less than or equal to the design
storage capacity ofthe facility. lfthe available stone capacity is greater than the design storage
capacity, this indicates that the plan calls for the application of nutrients that have not yet accumulated.
Ifavailable storage capacity is negative the estimated volume of accumulated waste exceeds the design
storage volume of the structure. Either of these situations indicates that the planned application interval
in the waste utilization plan is inconsistent with the structure`s temporary storage capacity.

Required Specifications For Animal Waste Management
1. Animal waste shall not reach surface watets of the state by runoff, drift,
manmade conveyances, direct application, or direct discharge during ,
operation or land application. Any discharge of waste that 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 Management Plan when there is a change in the
operation, increase in the number of animals, method of application,
receiving 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 held
Office Technical Guide Standard 393 - Filter Strips).
5. Odors can be reduced by injecting the waste or by 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).
.............................................................................................................................__.....
935864 Database Version 4.1 Date Printed: 12/26/2016 Specification Page 1

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.
g. Animal waste shall not be applied to saturated soils, during rainfall
events, or when the soil surface is frozen.
9. Animal waste shall be applied on actively growing crops in such a manner
that the crop is not covered with waste to a depth that would inhibit
growth. The potential for salt damage from animal waste should also be
considered.
10. Nutrients from waste shall not be applied in fall or winter for spring
planted crops on soils with a high potential for leaching. Wastelnutrient
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 that 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.
-----------------------------------------•------.....--------------------- .. .
935864 Database Version 4.1 Date Printed: 12/26/2016 Specification Page 2

15. Animal waste shall not be discharged into surface waters, drainageways,
or wetlands by a 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.
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.

Crop Notes
The following crop note applies to field(s):
Corn 1: CP, Mineral Soil, low -leachable
In the Coastal Plain, corn is normally planted when soil temperatures reach 52 to 55 degrees fahrenheit.
Review the Official Variety "green book" and information from private companies to select a high
yielding variety with the characteristics needed for your area and conditions. Plant 1-2" deep. Plant
populations should be determined by the hybrid being planted. Increase the seeding rate by 10% when
planting no -till. Phosphorus and potassium, recommended by a soil test can be broadcast or banded at
planting. When planting early in cool, wet soil, banded.phosphorus will be more available to the young
plants. An accepted practice is to apply 20-30 lbs/acre N and 20-30 lbs/acre phosphorus banded as a
starter and one-half the remaining N behind the planter. The rest of the N should be applied about 30-40
days after emergence. The total amount of N is dependent on soil type. When including a starter in the
fertilizer program, the recommended potassium and any additional phosphorus is normally broadcast at
planting. Plant samples can be analyzed during the growing season to monitor the overall nutrient status
of the corn. Timely management of weeds and insects are essential for corn production.
The following crop note applies to field(s): 1, 5
Fescue: Coastal Plain, Mineral Soil, Poorly Drained to Somewhat Poorly Drained.
Adaptation: Moderate to Marginal.
In the Coastal Plain, tall fescue can be planted Sept. 1 to Oct 15 (best) and Feb. 15 to Mar. 20. For
pure -stand broadcast seedings use 20 to 301b/ac., for drilled use 15 to 20 lb/ac. seed. Use certified seed
to avoid introducing weeds or annual ryegrass. Plant seed 0.25" to 0.5" deep for pure stands, 0.25" in
mixture with clovers. Tall fescue will tolerate soil wetness but not flooding or prolonged saturation; use
ladino clover for mixtures on these soils. Soil test for preplant and maintenance lime, phosphorus, and
potassium recommendations. Apply 40 to 60 lb/ac nitrogen at planting for pure stands only. Do not apply
N for mixtures with clovers but use proper legume inoculation techniques. Apply 150 to 200 lb/ac. N to
pure -stand fescue for hay production; reduce N rates by 25% for grazing. Apply N Feb. 1 to Mar. 20 and
Aug. 20 to Sept. 30, with equal amounts in each window. Refer to NCSU Technical Bulletin 305
Production and Utilization of Pastures and Forages in North Carolina for additional information or
consult your regional agronomist or extension agent for assistance.

Bermudagrass CP, Mineral Soil, Poorly Drained to Somewhat Poorly Drained.
Adaptation: Effective artificial drainage MUST be in place to achieve Realistic Yield Expectations
provided for these soils.
In the Coastal Plain, hybrid bermudagrass sprigs can be planted Mar. 1 to Mar. 31. Cover sprigs 1" to 3"
deep (1.5" optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and
wind. For, Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a
rate of 30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing
conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced 1' to 1.5' in row.
For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime, phosphorus,
potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 100 lb/ac N in
the establishment year in split applications in April and July. For established stands apply 180 to 240
lb/ac N annually in split applications, usually in April and following the first and second hay cuts.
Reduce N rates by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization
of Pastures and Forages in North Carolina for more information or consult your regional agronomist or
extension agent for assistance.

The following crop note applies to field(s):
Wheat: Coastal Plain, Mineral Soil, low -leachable
In the Coastal Plain, wheat should be planted from October 20-November 25. Plant 22 seed/drill row foot
at 1-1 1/2" deep and increase the seeding rate by 5% for each week seeding is delayed beyond the
optimum time. See the seeding rates table for applicable seeding rate modifications in the current NCSU
"Small Grain Production Guide". Also, .increase the initial seeding rate by at least 10% when planting
no -till. Adequate depth control when planting the wheat is essential. Review the NCSU Official Variety
"green book" and information from private companies to select a high yielding variety with the
characteristics needed for your area and conditions. Apply no more than 30 lbs/acre N at planting.
Phosphorus and potash recommended by a soil test can also be applied at this time. The remaining N
should be applied during the months of February -March. The total N is dependent on the soil type. Plant
samples can be analyzed during the growing season to monitor the nutrient status of the wheat. Timely
management of diseases, insects and weeds are essential for profitable wheat production.
The following crop note applies to field(s):
Double -Crop Soybeans, Coastal Plain: Mineral Soil, low -leachable
Double -crop soybeans should be planted as early in June as possible with planting completed by July 4tti.
When no -tilling soybeans in small grain straw, it is essential to manage the straw to achieve adequate
plant populations. Review the NCSU Official Variety "green book" and information from private
companies to select a high yielding variety with the characteristics needed for your area and conditions.
Plant 2-4 seed/row foot for 7-8" drills; 4-6 seed/row foot for 15" rows; 6-8 seed/row foot for 30" rows
and 8-10 seed/row foot for 36" rows. Increase the seeding rate by at least 10% for no -till planting.
Seeding depth should be 1-1 1/2" and adequate depth control is essential. Phosphorus and potash
recommended for the soybeans can be applied to the wheat in the Fall. Soybeans produce their own
nitrogen and are normally grown without additions of nitrogen. However, applications of 20-30 lbs/acre
N are sometimes made at planting to promote early growth and vigor. Tissue samples can be analyzed
during the growing season to monitor the overall nutrient status of the soybeans. Timely management of
weeds and insects is essential for profitable double crop soybean production.

NARRA�'.�VE QF OPERA T`ION
THIS OPERATION WAS SITED ACCORDING TO SENATE BILL 1217
ON 812196 BY TECHNICAL SPECIALIST, KEVIN WESTON OF
MURPHY FAMILY FARMS. THE FARM WAS SITED FOR A 2448
ADDITION TO THE 6120 EXISTING ANIMALS ON THE FARM.. ALL
THE LAND THAT WAS 1N PLACE ON THE FARM HAS BEEN
EVALUATED FOR WASTE APPLICATION. AN UPDATED,
CERTIFIED, WASTE MANAGEMENT PLAN HAS BEEN CREATED IN
CONJUNCTION WITH THE CERTIFIED IRRIGATION DESIGN FOR
THE NEW TOTAL, 8568 ANIMALS.
PLEASE NOTE THE CHANGE OF OWNERSHIP FORM THAT IS
ATTACHED TO THE APPLICATION PACKET. DURING THE
PROCESS OF GETTING THE PACKAGE TOGETHER I NOTICED
THAT THIS FARM (31-344) HAD NEVER BEEN PLACED IN MR. COY
CARTER'S NAME ACCORDING TO YOUR RECORDS . IN EARLY
1994 WHEN THIS FARM CHANGE HANDS THE PROCEDURE FOR
NOTIFYING DWQ WAS NOT BEING ENFORCED AND WAS RATHER
VAGUE AT THAT PARTICULAR TIME. I TOOK IT UPON MYSELF
TO DO THE HOUSE KEEPING ON THIS ISSUE BY ASSISTING MR.
CARTER WITH THE CURRENT CHANGE OF OWNERSHIP FORM IN
ORDER TO UPDATE THE RECORDS IN ACCORDANCE WITH
CURRENT STANDARDS.

System Calibration
Information presented in manufacturer's charts are based on average operation
conditions with relatively new equipment. Discharge rates and application rates
change over time as equipment gets older and components wear. In particular,
pump wear tends to reduce operating pressure and flow. With continued use,
nozzle wear results in an increase in the nozzle opening which will increase the
discharge rate while decreasing the wetted diameter.
You should be aware that operating the system differently than assumed in the
design will alter the application rate, diameter of coverage, and subsequently the
application uniformity. For example, operating the system with excessive pressure
results in smaller droplets, greater potential for drift, and accelerates wear of the
sprinkler nozzle. Clogging of nozzles can result in pressure increase. Plugged
intakes or crystallization of mainlines will reduce operating pressure. Operating
below design pressure greatly reduces the coverage diameter and application
uniformity.
For the above reason, you should calibrate your equipment on a regular basis to
ensure proper application rates and uniformity. Calibration at least once every
three years is recommended. Calibration involves collecting and measuring flow at
several locations in the application area. Any number of containers can be used to
collect flow and determine the application rate. Rain gauges work best because
they already have a graduated sca!e from which to read the application amount
without having to perform additional calculations. However, pans, plastic buckets,
jars, or anything with a uniform opening and cross-section can be used provideo
the liquid collected can be easily transferred to a scaled container for measuring.
For stationary sprinklers, collection containers should be located randomly
throughout the application area at several distances from sprinklers. For traveling
guns, sprinklers should be located along a transect perpendicular to the direction of
pull. Set out collection containers 25 feet apart along the transect on both sides of
the gun cart. You should compute the average application rate for all
nonuniformity of the application. On a windless day, variation between containers
of more than 30 percent is cause for concern. You should contact your irrigation
dealer or technical specialist for assistance.

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

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

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

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

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

Possible Causes of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure. Types
of failures include leakage through the bottom or sides, overtopping, and breach of the
dam. Assuming proper design and construction, the owner has the responsibility for
ensuring structure safety. Items which may lead to lagoon failures include:
Modification of the lagoon structure ---an example is the placement of a pipe
in the dam without proper design and construction. (Consult an expert in
lagoon design before placing any pipes in dams.)
Lagoon liquid levels ---high levels are a safety risk.
Failure to inspect and maintain the dam.
Excess surface water flowing into the lagoon.
Liner integrity ---protect from inlet pipe scouring, damage during sludge
removal, or rupture from lowering lagoon liquid level below groundwater
table.
NOTE: If lagoon water is allowed to overtop the darn, the moving water will soon cause
gullies to form in the dam. Once this damage starts, it can quickly cause a large discharge
of wastewater and possible dam failure.

Q E;.'SU ATTACHED WASTE UTILIZATION PLAN

OPERATION AND MAINTENANCE PLAN
------------------------------
This lagoon is designed for waste treatment with minimum odor
control. The time required for the planned fluid level to be
reached may vary due to soil conditions,flushing operations, and
the amount of fresh water added to the system.
Land application of waste water is recognized as an acceptable
method of disposal. Methods of application include solid set,
center pivot, guns, and traveling gun irrigation. Care should be
taken when applying waste to prevent runoff from the field or damage
to crops.
The following items are to be carried out:
1. It is strongly recommended that the treatment lagoon be pre -
charged to 1I2 its capacity to prevent excessive odors during
start-up. Pre -charging reduces the concentration of the initial
waste entering the lagoon thereby reducing odors. Solids should be
covered with effluent at all times.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see Attachment B)
before land application.
3. $egin pump -out of the lagoon when fluid level reaches eleva-
tion .-51.8 as marked by permanent markers. Stop pump -out when
the fluid level reaches elevation .49..5 or before fluid depth is
less than 6 feet deep (this prevents the loss of favorable
bacteria) .
4. The recommended maximum amount to apply per irrigation is
one (1) inch and the recommended maximum application rate is 0.4
inch per hour.
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. The Clean Water Act of 1977 prohibits the discharge of
pollutants into waters of the United States. The Department of
Environment, Health,_ and Natural Resources, Division of Environ-
mental Management, has the responsibility for enforcing this law.

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

A total of four (4) soil borings were taken on this site by Billy Houston, SCS, to
determine if the existing soils would be suitable for embankment material for the lagoon.
Two 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 a nail @ Sta. G15+00.
The estimated high water table elevation = 49.0 Feet, +/ -
Using the Unified Classification System, the results of the borings are as follows:
Boring #1 : 0 Ft. -- 2 Ft. — SM material (silty sand)
2 Ft. -- 5 Ft. — SM,SC materials (silty sands; clayey sands)
5 Ft. — E Ft. -- SC material (clayey sands; sand —clay mixtures)
6 Ft. -- I f Ft. -- SC,SM materials (clayey sands; silty sands)
Boring #2: 0 Ft. -- 2 Ft. — SM material (silty sand)

Based on the results of these borings, SOME of the soils available an 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 requ€red.

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

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

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

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

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

Possible Causes of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure. Types
of failures include leakage through the bottom or sides, overtopping, and breach of the
dam. Assuming proper design and construction, the owner has the responsibility for
ensuring structure safety. Items which may lead to lagoon failures include:
Modification of the lagoon structure ---an example is the placement of a pipe
in the dam without proper design and construction. (Consult an expert in
lagoon design before placing any pipes in dams.)
Lagoon liquid levels ---high levels are a safety risk.
Failure to inspect and maintain the dam.
Excess surface water flowing into the lagoon.
Liner integrity ---protect from inlet pipe scouring, damage during sludge
removal, or rupture from lowering lagoon liquid level below groundwater
table.
NOTE: If lagoon water is allowed to overtop the dam, the moving water will soon cause
gullies to form in the dam. Once this damage starts, it can quickly cause a large discharge
of wastewater and possible dam failure.
