Subject: CDP Farm
Facility # AWS310557
State Digester General Permit
Dear Ms. Lawson,
C AVA N A U G H
Stewaia,_t,p ,i,, s,6- ,_;,ovation
Cavanaugh & Associates, P.A., 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 CDP Farm. The subject project is located in Duplin County, North Carolina.
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 the FEMA FIRM map labeled with the 'Proposed Digester Site'.
5. One (1) copy of the permit form Section 3.6 components.
6. One (1) full-size set of the engineering plans, as well as one (1) 11"x17" set.
The applicable setbacks (per the 'Swine Farm Siting Act' and 15A NCAC 02T) for the proposed digester
are shown on sheet C.2.35.3 of the engineering plans, which indicates that the digester will be:
1. Greater than 100' from all wetlands / perennial streams / perennial waterbodies (per 15A NCAC
02T .1304(b)(11)).
2. Greater than 2,500' from all schools, hospitals, churches, outdoor recreational facilities, national
parks, State Parks, and child care centers.
3. Regarding the setback from property boundaries, there's one property within 500' of the
proposed digester that's also closer than the existing swine houses and lagoons, so the farm
owner will obtain a setback waiver from that property owners (as indicated on sheet C.2.35.3).
4. Regarding the setback from occupied residences, there's one residence within 1,500' of the
proposed digester that's also closer than the existing swine houses and lagoons, so the farm
owner will obtain a setback waiver from that residence owner (as indicated on sheet C.2.35.3).
Influent sampling will be accomplished via sampling from the influent lift station or gravity main
conveying flushed manure to the digester, where applicable. Effluent sampling will be accomplished via
sampling from the level control wet well.
Regarding usage of the biogas, the applicant plans to begin export of the renewable energy resource
within 6 months of collecting gases in accordance with Session Law 2023-63 (2023 Farm Act).
Cavanaugh & Associates, P.A. PO Box 11197 Winston-Salem, NC 27116, 1-877-557-8923, www.covanaughsolutions.com

Regarding estimate of daily volume of biogas, the daily volume of biogas varies based on animal stocking
numbers, animal age, and climatic variations. A gross estimate that is commonly used for in -ground,
ambient temperature digesters is about 2 cubic feet of biogas per pig occupant in the farm per day;
however, the actual amount of biogas produced by the farm may vary significantly given the
considerations described above.
Regarding emergency flare, the applicant has made arrangements for the use of a portable flare should
the need arise, which will be available and used if necessary for compliance with Session Law 2023-63
(2023 Farm Act).
Regarding the location/method for measuring waste levels in the digester, the liquid level in the digester
will be observed and measured via the level control wet well.
Regarding general information regarding any Air Quality permits, a determination has been made that
the emissions fall below the minimum threshold for permitting; separate communications and
correspondence have been concluded with the Division of Air Quality regarding this topic.
Please do not hesitate to contact our office should you have any questions, comments, or require any
additional information.
Regards,
Cavanaugh & Associates, P.A.

Note: Both 'Rainfall In Excess Of Evaporation' and 'Storm Storage' are shown as 0 cf for the digester because the HDPE
cover prevents rain from entering the wastewater system and therefore doesn't need to be included in these volume
calculations; the rain that falls on the cover is simply pumped off of the cover with a rainwater pump(s).
That being said, per the NRCS 366 Anerobic Digester standard, rainfall is included in determining the operational
volume of the digester. The NOAA Atlas 14 30yr normal rainfall data for the area has been used to determine the 25-year,
24-hour rainfall on the digester. With this data, the following value has been used for the the 25-year, 24-hour rainfall event:

Narrative
'CDP Farm' will utilize existing barns with slotted floors over flushing pits to collect manure.
Upon flushing, Barn 1 will gravity flow waste through a 12" pipe to an influent lift Station (ILS). The
influent lift Station will utilize two 20 hp GEA pumps, with a typical flow of approx. 940 gpm (1 pump)
through an 8" HDPE (DR 17) forcemain into the proposed anaerobic digester.
Upon flushing, Barn 2 will gravity flow waste through a 12" pipe to the proposed anaerobic digester.
After treatment in the anaerobic digester (178,968 cubic feet of total volume, 139,773 cubic feet at
Operating Level), effluent will gravity flow through the 12" digester outlet pipe to the level control wet
well (LC), which connects to a 12" pipe to the existing 'Lagoon 2'.
The transfer pump will pump from the existing 'Lagoon 2' to the existing 'Lagoon 1' using a 10 hp GEA
pump, with a typical flow of approx. 440 gpm through a 6" HDPE (DR 17) forcemain in order to balance
the lagoons as needed.

If you n move the sludge every 5 years, you will have approximat aly 0 pounds of plant

rate of 00 pounds of nitrogen per acre, you will need 0 acreas a land. If you apply the sludge
to com 3t a rate of 125 pounds per acre, you will need 0 acres of land. Please note that these
are on[,estimates of the PAN produced and the land required to utilize that PAN. Actual values
may o y be determined by sampling the sludge for plant availab e nitrogen content prior to application
Actual i itilization rates will vary with soil type, crop, and realistic y ield expectations for the specific
applica ion fields designated for sludge application at time of rerr oval.
APPLICATION OF WASTE BY IRRIGATION:
The irri ation application rate should not exceed the intake rate the soil at the time of irrigation
such t runoff or ponding occurs. This rate is limited by initial it moisture content, soil
structu e, soil texture, water droplet size, and organic solids. Thi application amount should not
exceec the available water holding capacity of the soil at the timt of irrigation nor should the
plant a Failable nitrogen applied exceed the nitrogen needs of thE crop.
If surfs irrigation is the method of land application for this plan it is the responsibility of the
produ r and irrigation designer to ensure that an irrigation systf m is installed to properly
irrigate the acres shown in the preceding table. Failure to apply he recommended rates and
amoun s of nitrogen shown in the tables may make this plan inv, lid.
*This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. I many situations, the application
amount shown cannot be applied because of the nitn Ven limitation. The maximum
application amount shown can be applied under optii ium soil conditions.
Your f ility is designed for >180 days of temporary storage and the temporary storage must
be re ved on the average of once every 6 months. In no ins ce should the volume of the
waste tored in your structure be within the 25 year 24 hour sto storage or one foot of
freebo rd except in the event of the 25 year 24 hour storm.
It is th responsibility of the producer and waste applicator to en ure that the spreader equipment
is opei ated properly to apply the correct rates to the acres show in the tables. Failure to apply
the rec ommended rates and amounts of nitrogen shown in the t itiles may make this plan invalid.
Call yc ur technical specialist after you receive the waste analysis report for assistance in
detem ining the amount of waste per acre and the proper applic ition prior to applying the waste.

EMERGENCY ACTION PLAN
PHONE NUMBERS
DIVISION OF WATER QUALITY (DWQ)
EMERGENCY MANAGEMENT SERVICES (EMS)
SOIL AND WATER CONSERVATION DISTRICT (SWCD)
NATURAL RESOURCES CONSERVATION SERVICE (NRCS)
COOPERATIVE EXTENSION SERVICE (CES)
This plan will be implemented in the event that wastes from your operation are leaking,
overflowing or running off site. You should not wait until wastes reach surface waters or
leave your property to consider that you have a problem. You should make every effort to
ensure that this does not happen. This plan should be posted in an accessible location
for all employees at the facility. The following are some action items you should take.
1. Stop the release of wastes. Depending on the situation, this may or may not be possible. Suggested
responses to some possible problems are listed below.
A. Lagoon overflow - possible solutions are:
a) Add soil to berm to increase elevation of dam.
b) Pump wastes to fields at an acceptable rate.
c) Stop all flow to the lagoon immediately.
d) Cali a pumping contractor.
e) Make sure no surface water is entering lagoon.
B. Runoff from waste application field -actions include:

the salvage of part of a dead animal's value without endangering human or animal health.
(Written approval by the State Veterinarian must be attached).
Mass Mortality Plan
Mass mortality plans are required for farms covered by an NPDES permit. These plans are
also recommended for all animal operations. This plan outlines farm -specific mortality man-
agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup-
ports a variety of emergency mortality disposal options; contact the Division for guidance.
• A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated
when numbers of dead animals exceed normal mortality rates as specified by the State
Veterinarian.
• Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary
Division regulations and guidance.
• Mass burial sites are subject to additional permit conditions (refer to facility's animal
waste management system permit).

Definitions
Anaerobic Digestion - A method of wastewater treatment that utilizes the natural
decomposition of the waste by bacteria in the absence of oxygen to produce gases commonly
referred to as biogas.
Anaerobic Digester - A basin or tank that holds the wastewater for anaerobic digestion.
Biogas - Produced by anaerobic digestion, and is typically comprised of approximately 55%
methane (the primary constituent of natural gas), with the remainder being mostly carbon
dioxide (COA.
Anaerobic Digester System O&M Page 2 of 16

II. Introduction
The proposed swine manure biogas project uses anaerobic digestion of hog barn waste to
produce biogas (consisting of approximately 65% methane, which is the primary constituent of
natural gas) which is collected, conditioned, and ultimately injected into the utility's natural gas
pipeline. Each hog farm site includes influent collection piping from the hog barns, an anaerobic
digester or covered lagoon, a digester mixing system, a biogas conditioning system to remove
moisture, a back-up flare unit, and a biogas transfer pipe leading to the Gas Upgrading System
(GUS).
The anaerobic digesters at each farm site include an HDPE membrane cover to capture the
biogas generated by the anaerobic digestion process. The anaerobic digester is partially mixed
by pumping, and provides sufficient detention time to effectively reduce the volatile suspended
solids in the raw waste by anaerobic digestion. The reduction of volatile solids through
microbial processes produces an energy -rich biogas, which is a valuable commodity.
There are two (2) types of solids found in liquid waste: organic and inorganic. The inorganic
solids are "non -treatable," but they are normally present in such small quantities that they are
considered insignificant in the treatment process. However, excessive quantities of sand, grit,
clay, etc. can cause the need to pump out the digester more often.
The organic solids will break down and decompose by biochemical reduction. The bacteria that
is grown and maintained in the system are harmless anaerobic and anoxic bacteria. These same
bacteria are provided by nature and are found in streams, lakes, and in the soil to destroy dead
plants and animals. The difference is that in the treatment process, man has provided an ideal
environment for a concentration of these bacteria to feed and grow; thus, the biological action
is greatly accelerated.
Raw wastes are the food for the bacteria in the system. The anaerobic digester contains certain
populations of bacteria that do not require the presence of oxygen.
In addition to the information covered by this manual, the system operator should become
familiar with the characteristics of the wastewater being treated and with local, state, and
federal laws which may apply to the operation of the system.
Design Flow - The waste collection system, influent pump station (where necessary), and
anaerobic digester systems have been designed to handle the Average Daily Flow Rate (ADF) of
the farms in which they are connected, including the manure and wastes generated by the
animals, flushing liquids, and other wastes typical of confined swine animal housing. All
treatment units were designed for the Design Flow for continuous, seven (7) days per week
operation.
III. Description of the Operational Components
Below are listed the major component operations.
1) Gravity Collection Pipe
Anaerobic Digester System O&M Page 3 of 16

The gravity collection pipe receives the flushed waste from the hog barns and directs
that waste to the influent pump station (or mixing pump station, where applicable).
During normal operation, the pipe should be free -flowing, with no clogs present, in
order to transport waste to the influent pump station or other downstream processes.
The gravity collection pipe includes a series of clean -outs that provide access to the
gravity collection pipe for removal of a clog or blockage via use of a sewer snake or
similar apparatus should the need arise.
Sending flushed waste from the hog barns to the gravity collection pipe is the farmer's
responsibility. The operator of the biogas system should periodically check each hog
barn waste outlet to ensure that there are no overflows, clogs, etc. The influent pump
station includes an analog run-time meter for each pump, which can be monitored by
the operator to ensure the pumps are operating for sufficient times to indicate proper
flushing by the farm owner.
2) Influent Pump Station (where necessary)
The influent pump station receives waste from the gravity collection pipe and pumps
that waste to the anaerobic digester via buried forced main. The waste enters the
digester at the opposite end of the digester outlet (so "new' waste must flow through
the curtain baffle system of the digester, resulting in effective treatment of the waste).
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 4 floats.
The lowest float is the "pump off' float, and is set at approximately 12" above the
bottom of the wet well. The pump station should not run if the liquid level is below this
float.
The 2nd lowest float is the "lead pump on" float, and is set at an elevation approximately
2" below the inlet pipe invert, and above the "lead pump off' float. When the liquid
level is above this float, only one pump will run at any given time, 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).
The 3rd lowest float is the "lag pump on" float, and is set approximately 6" above the
"lead pump on" float. If the liquid level fills above this float, then both pumps will run
until the "pump off' float is disengaged.
The 4th and highest float is the "high level alarm" float. When the liquid level is above
this float, an audible and visual alarm is triggered to alert the operator system that there
is a problem that has prevented pump operation.
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 together
by a tee, and the downstream pipe leads to the inlet of the digester.
Anaerobic Digester System O&M Page 4 of 16

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,
however, 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).
The alternating of pumps can also be changed within the control panel, where a toggle
switch allows the operator to choose "Lock 1", "Alternate", or "Lock 2". During normal
operation, the toggle switch will remain at "Alternate" in order to alternate the pumps
between pumping cycles, but the operator can choose to lock the use of Pump #1 or
lock the use of Pump #2 if needed.
In the event of a pipe clog or 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 an Influent
Pump Station, the waste flows from the barns to the Mixing Pump Station, which is
further described below.
3) Anaerobic digester
The anaerobic digester receives all raw wastes from the hog barns. The complex organic
wastes are broken down to simpler compounds by the anaerobic digestion process. As
a part of the anaerobic process, bio gases (including methane, carbon dioxide, and
hydrogen sulfide) are produced. These gases are captured by an impermeable cover
and then directed to the biogas conditioning system for dehydration and pressurization.
The gases are collected in perforated piping underneath the cover, which are connected
to a main pipe that connects to the conditioning system. The wastes are held for about
45 days to allow the biological process to complete. The sludge that settles at the
bottom of the digester is periodically removed by connecting portable pipes and pumps
to the sludge removal pipes in the digester, and disposed of by permitted means on the
farm or by a contract sludge hauler.
During normal operation, the digester cover will likely be "inflated" like a balloon due to
the biogas that's trapped beneath. The cover should be free of excessive accumulation
of rainwater, and should not show signs of any damage or leaks. The presence of foul
odor, a strong wastewater smell, or "dirty" water on the cover may indicate that there is
a leak. If such odors or dirty water are observed, the operator should carefully inspect
the cover for leaks, and take action to repair the cover temporarily with adhesive tape.
Temporary repairs should be followed with a permanent repair or patch as soon as
possible.
Anaerobic Digester System O&M Page 5 of 16

4) Mixing Pump Station
The mixing pump station slowly mixes the waste that has been collected in the
anaerobic digester, which provides for more efficient methane production than would
be achievable without any mixing.
During normal operation, the pumps will run at the same time for several hours per day
to mix the waste in the anaerobic digester. A common schedule for the pumps would
be 6 hours on, then 6 hours off, and so on.
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 operation), (2) Off, or (3) "Hand" (i.e.,
manual operation).
5) Effluent Pump Station (where necessary)
The effluent pump station receives liquids from the anaerobic digester and pumps that
waste to the downstream influent storage lagoon via buried forced main. The liquid
enters the effluent pump station at the opposite end of the digester inlet (so "new"
waste must flow through the curtain baffle system of the digester, resulting in effective
treatment of the waste).
During normal operation, the pump station will run based on the liquid level in the wet
well, which is triggered by 4 floats.
The lowest float is the "pump off' float, and is set at approximately 12" above the
bottom of the wet well. The pump station should not run if the liquid level is below this
float.
The 2nd lowest float is the "lead pump on" float, and is set at an elevation approximately
2" below the inlet pipe invert, and above the "lead pump off' float. When the liquid
level is above this float, only one pump will run at any given time, 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).
The 3rd lowest float is the "lag pump on" float, and is set approximately 6" above the
"lead pump on" float. If the liquid level fills above this float, then both pumps will run
until the "pump off' float is disengaged.
The 4th and highest float is the "high level alarm" float. When the liquid level is above
this float, an audible and visual alarm is triggered to alert the operator via telemetry
system that there is a problem that has prevented pump operation.
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
Anaerobic Digester System O&M Page 6 of 16

when needed, such as when servicing the upstream pump). The two pipes join together
by 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 lagoon. 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, however, 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)

switch allows the operator to choose "Lock 1", "Alternate", or "Lock 2". During normal
operation, the toggle switch will remain at "Alternate" in order to alternate the pumps
between pumping cycles, but the operator can choose to lock the use of Pump #1 or
lock the use of Pump #2 if needed.
The gravity outlet of the anaerobic digester leads to the inlet of the effluent pump
station, and the invert is set at the freeboard of the digester so that the digester
maintains a constant level. The inlet pipe to the effluent pump station should remain
submerged in water at all times to prevent the escape of gases from beneath the
digester cover.
Note: Some farms do not have Effluent Pump Stations; rather than using an Effluent
Pump Station, the waste gravity flows from the anaerobic digester to the lagoon.
6) Storage Basin
The effluent of the anaerobic digester flows from the anaerobic digester outlet pipe to
the storage basin. The storage basin is used to store the treated effluent subsequent to
anaerobic digestion. The individual farm owners are responsible for the operation and
maintenance of the storage basins. However, as this is a critical part of the integrated
system, the 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. The outlet pipe from the anaerobic digester into the storage lagoon should
remain submerged at all times to prevent the escape of gases 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.
7) Biogas Conditioning System
Anaerobic Digester System O&M Page 7 of 16

The Biogas conditioning system receives biogas from the anaerobic digester and
removes moisture from the biogas by means of compression and heat exchangers.
This system will be managed by a 3rd party, but the information is included in this O&M
for reference.
The biogas from the anaerobic digester is commonly at 100% relative humidity; the
biogas is purported to be near 6% relative humidity after going through the conditioning
system. The moisture that is removed should be directed back to the digester mixing
pump station or other suitable reception pipe for proper management of the
condensate.
During normal operation, the conditioning system should run without any need for
input from the system operator. Audible and visual alarms will indicate issues with the
system. The discharge pressure and flow rate can be manipulated by the operator
through adjustment of the pressure regulator on the bypass line and through
adjustment of the variable frequency drive. The automatic shutoff feature, whereby the
operator can set the vacuum pressure shutoff point. As the biogas conditioning skid
approaches this setpoint, it will automatically reduce blower or compressor speed to
seek a flowrate that matches the biogas production. If the vacuum pressure exceeds
the setpoint, the biogas conditioning skid will shutdown and trigger an alarm to the
operator via telemetry system.
8) Flare
During normal operation, the flare located at each farm should not necessary. In times
of need, such as catastrophic failure of the biogas conveyance pipeline, the flare may
need to be operated to consume excess accumulated biogas from the digester. The
flare is not an automated system, and the Operator must articulate the biogas piping
control valving to direct biogas from the digester to the flare, and ignite the flare. Care
must be taken by the Operator in igniting the flare, as biogas is highly flammable.
Each flare also has a condensate trap manhole. Contained inside is a small PVC drain
pipe and PVC drain valve. The PVC drain valve should remain closed at all times unless
the Operator is removing condensate. Should the valve be left open, biogas will escape
from the piping. Periodically, and at a frequency determined appropriate by the
Operator, these condensate traps will be opened momentarily to drain and remove any
condensate collected in the piping. It is recommended that the condensate drain valve
only be opened when the biogas piping is pressurized, as should the valve be opened
under no pressure, ambient air may enter the biogas piping and challenge biogas
upgrading by the GUS.
9) Transfer Pump
The transfer pump transfers accumulated effluent among available storage basins as the
farm owner deems necessary to optimize effluent storage. The transfer pumps are
simply and manually operated through use of a local disconnect. Under normal
Anaerobic Digester System O&M Page 8 of 16

circumstances, the transfer pump will only be used periodically and infrequently by the
farm owner.
10) Stormwater Removal Pump
A stormwater removal pump is kept at each digester site in order to remove
accumulated rainwater from the top of the basin cover. The pump can be powered by
any standard 120v outlet that's available nearby, such as the accessory outlet installed
adjacent to the digester mixing pump station. The pump should be placed in a low spot
on top of the cover, and the pump outlet should lead to an appropriate area for
stormwater discharge (on some sites, pipes have been placed to easily receive the pump
outlet pipe, which leads to the natural stormwater drainage swales on the property).
IV. Description of Anticipated Maintenance
Once the system has been started up and is operating efficiently, very little maintenance will be
required. Simple tests should be periodically performed to evaluate the performance of the
wastewater treatment components, and the system components visually inspected daily.
A well -operated, properly adjusted, system will exhibit the following visible signs of proper
maintenance:
• All pipes should be intact and watertight.
• The pumps should be nearly silent with little to no vibration.
• The anaerobic digester should be free of excessive accumulation of rainwater.
• Accumulated rainwater may be removed with a portable sump pump. The pumped water
may be discharged safely on adjacent vegetated areas, or used for a more beneficial
purpose as permitted.
• The anaerobic digester cover should be free of any tears, punctures, or failures.
• There should be no strong odors coming from the digester or flare.
• The storage basin should be clean and free of floating debris. The liquid should be clean and
clear.
A. Routine System Maintenance Instructions
For optimum system operation and maximum treatment efficiency, daily maintenance is
necessary. In addition to the daily maintenance, all mechanical equipment should be
cleaned weekly and lubricated as often as needed, as specified in the operations and
maintenance manual for each piece of equipment provided by the equipment
manufacturer.
The farm owner will need to periodically remove accumulated sludge from the anaerobic
digester. Accumulated sludge may be removed via the anaerobic digester mixing pumps. To
use these pumps for sludge removal, the system operator should cease mixing pump
operation 48 hours prior to the date of desired sludge removal to allow for settling of
heavier sludge to the pump inlet. A quick disconnect fitting is provided for each mixing
pump that will facilitate the connection of the pump discharge to sludge application
Anaerobic Digester System O&M Page 9 of 16

equipment as chosen by the farm owner, such as slurry tanks or umbilical hose application
systems. All sludge applications should be done in accordance with the approved waste
utilization plan and nutrient management plan for the farm or hauled via tanker to an
approved application site by a contract sludge hauler.
Typically, a small amount of sludge will need to be removed from the anaerobic digester
every other year. The system operator can monitor sludge accumulation via the inspection
ports on top of the digester cover. A pipe or gauge with graduated markings used to
determine depth may be used to assess the sludge depth in the digester. Care should be
taken when inserting the gauge or pipe to not apply excessive pressure or otherwise
puncture the digester liner. Sludge accumulation should be assessed on an annual basis by
the system operator. As the digester cover typically accumulates biogas, care should also be
taken by the operator to remove as much accumulated biogas as possible prior to opening
the inspection port and measuring sludge accumulation. As biogas production slows during
cold weather, it is recommended that this measurement occur during the winter when
biogas accumulation is at a minimum.
After completion of sludge removal activities using the anaerobic digester mixing pumps,
the operator should reconnect all fittings and piping as found prior to the sludge removal
and re-engage the digester mixing pumps operation in accordance with the schedule and
manner in which they had been previously operated.
See Appendix C of this document for an operations and maintenance checklist (daily,
monthly, quarterly, semi-annually, annually).
