Application No. ADS820385
Farm 2701, 2102 and 2105
Sampson County
Dear Mrs. Lawson,
CAVANAU G H
Stewardship Through Innova,,.
Cavanaugh & Associates, P.A., on behalf of Hd3 Farms of the Carolinas LLC has reviewed your Additional
Information Request, dated April 26, 2023, for the subject permit modification application for 'Farm
2701, 2102 and 2105', which is noted to have been received by the Division on December 19, 2022; and
has developed responses and additional supporting information to address each item in your letter. For
your convenience, we have repeated the comments below in bold font, followed by the responses in
italicized font.
1. Setbacks — Sheet C.2.7.3 shows that the location of the proposed digester does not meet the
Siting Act requirements for:
- distance from setback from the nearest residence not owned by the producer, which is
1500ft, G.S. §106-803(a)(1). As shown, the digester top of embankment is 266 feet from
the nearest residence.
- distance from property boundary, which is 500 ft, G.S. §106-803(a)(3). As shown, the
digester top of embankment is 120 feet from the property boundary.
- distance from a well that supplies water for human consumption, G.S. §106-803(a)(5). The
nearest home (266 ft from digester) would have a well. Please show location of well and if
it meets setback requirements.
Please provide documentation of compliance with the Siting Act, either through additional
setbacks or documentation of permission as described in G.S. §106-803(b). No
Waiver/Easement option regarding setbacks from wells is included in G.S. §106-803(b)
Response: Please see attached, amended plan set depicting the relocation of the proposed
digester, as well as amended supporting documents.
Note that the relocated digester requires a change to the existing WUP, which is
pending by the grower and is expected to be submitted within a week or so.
2. Mailing Address —The Mailing Address shown on the application differs from the Mailing
Address of Record for owner HD3 Farms of the Carolinas, LLC. Please confirm the correct
Mailing Address.
Response: Please note the correct mailing address is as follows:
PO Box 2107
Elizabethtown, NC 28337

3. Owner Signature —The application submitted was not signed by the permittee, Mr. HD3 Farms
of the Carolinas, LLC. Please sign and date. There is a signature for a Farm Manager, but the
name was not printed in; please fill in this information as well.
Response: Please see signed permit application attached.
4. Stormwater Outlet— Please provide atypical detail for outlet for stormwater removed from
digester covers. Please also indicate stormwater outlet location.
Response: Please see attached plan sheets showing the location of the proposed
stormwater outlet (site plan sheet C.2.7.1), and typical detail (detail sheet C.3.8).
It should be noted that the design low point in the lagoon cover will be
determined by the cover supplier/installer, and provided to the permittee as a
submittal drawing prior to installation; therefore, the specific location depicted
on the attached site plan may change, and if so, such change will be reflected in
the record drawings upon completion of construction.
5. Biogas Use as a Renewable Energy Resource —Please provide information for the intended
onsite and/or offsite use of biogas. Please include expected timeline regarding completion of
digester system and utilization of gas as a renewable energy resource.
Response: The applicant plans to utilize the biogas produced from the facility to generate a
renewable energy resource for export off the farm. Specific details of how the
applicant plans to do this are not yet released, but the applicant plans to begin
export of the renewable energy resource within 12 months of commencing
construction.
6. Gas Generation Estimate —Please submit an estimate for the daily volume of biogas to be
generated by the proposed Digester.
Response: 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.
7. Emergency Flare— Please provide location/identification for the emergency flare(s).
Response: An emergency flare will not be provided for the proposed farm. Rather, should
the applicant need to dispose of excess biogas, the system operator will open
one or more emergency vent ports to be installed as part of the HDPE digester
cover system, and release the biogas.
8. Secondary Containment —Please confirm design plans to prevent overflow from the lift/pump
station.

Response: An overflow prevention pipe is included in the influent lift station that will direct
flushed manure to the existing lagoon, via gravity, should the lift station fail to
pump for any reason. The invert for the overflow prevention pipe is set such that
the gravity pipe will convey the flushed manure to the adjacent lagoon prior to
overtopping the influent lift station. In the case where the flushed manure is
directed to the mixing station, the gravity connection to the digester within the
mixing pump station will convey flushed manure into the digester should the
mixing pumps not operate.
9. Influent/Effluent Sampling —Please indicate location for sampling of influent to and effluent
from each digester.
Response: 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.
10. Waste Level Gauge — Please indicate location/method for measuring waste levels in the
digester, as it does not gravity feed to the secondary containment.
Response: We are unclear of the use of "secondary containment" in this comment; the
liquid level in the digester will be observed and measured via the level control
station.
11. Odor Control Checklist — The Odor Control Checklist that was included did not have any Best
Management Practices (BMPs) selected. Please review and resubmit if any BMPs are to be
implemented. Please include the Permit Number on all pages of the Checklist and date page 1.
Response: Please see attached, corrected Odor Control Checklist.
12. Insect Control Checklist — The Insect Control Checklist was not included in the application.
Please provide as a required component of the CAWMP.
Response: Please see attached, corrected Insect Control Checklist.
13. Mortality Management Checklist — No mortality management method was indicated/selected
on the Mortality Management Checklist included with the application. The Checklist was
signed by the owner, but not dated. The Checklist did not include Technical Specialist signature
or signature date. Please provide a completed Checklist.
Response: Please see attached, corrected Mortality Management Checklist.
14. Emergency Action Plan — The Emergency Action Plan was not included in the application.
Please provide as a required component of the CAWMP.
Response: Please see attached Emergency Action Plan.

15. O&M Plan —The Contact Information for Christine Lawson should be updated as follows:

Narrative
'Farm 2701, 2102 and 2105' will utilize existing barns with slotted floors over flushing pits to collect
manure.
Upon flushing, Barns 1-4 will gravity flow waste through a 12" pipe to an influent lift station. The
influent lift station will utilize two 2x10 hp GEA pumps, with a typical flow of approx. 790 gpm (1 pump)
through an 8" HDPE (DR 17) forcemain into the anaerobic digester. In the event of pump failure, a 12"
bypass pipe will gravity flow waste to the existing Lagoon 1 to prevent overflow of the influent lift
station.
Upon flushing, Barns 5-8 will gravity flow waste through a 12" pipe to the anaerobic digester.
After treatment in the anaerobic digester (565,128 cubic feet total volume, 464,130 cubic feet at
operating level), the effluent will enter the level control station. The level control station will utilize two
10 hp GEA pumps, with a typical flow of approx. 460 gpm through a 6" HDPE (DR 17) forcemain to the
existing Lagoon 2, where it will be irrigated in accordance with the waste utilization plan. Additionally,
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. 450 gpm through a 6" HDPE (DR 17) forcemain in order to balance
the lagoons as needed. Additionally, existing piping will be utilized to transfer the effluent to existing
Lagoon 3 and existing Lagoon 4

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:
a) Immediately stop waste application.
b) Create a temporary diversion to contain waste.
c) Incorporate waste to reduce runoff.
d) Evaluate and eliminate the reason(s) that cause the runoff.
e) Evaluate the application rates for the fields where runoff occurred.
C. Leakage from the waste pipes and sprinklers - action include:
a) Stop recycle pump.
b) Slop irrigation pump.
c) Close valves to eliminate further discharge.
d) Repair all leaks prior to restarting pumps.
D. Leakage from flush systems, houses, solid separators - action include:
a) Stop recycle pump.
b) Stop irrigation pump.
c) Make sure siphon occurs.
d) Stop all flow in the house, flush systems, or solid separators.
Leakage from base or sidewall of lagoon. Often this is seepage as opposed to flowing leaks -
possible action:
a) Dig a small sump or ditch from the embankment to catch all seepage, put in a submersible
pump, and pump back to lagoon.
b) If holes are caused by burrowing animals, trap or remove animals and fill holes and
compact with a clay type soil.
c) Have a professional evaluate the condition of the side walls and the lagoon bottom as soon
as possible.

2. Assess the extent of the spill and note any obvious damages.
a- Did the waste reach surface waters?
b. Approximately how much was released and for what duration?
c. Any damage notes, such as employee injury, fish kills, or property damage?
d. Did the spill leave the property?
e. Does the spl I have the potential to reach surface waters?
f. Could a future rain event cause the spill to reach surface waters?
g. Are potable water wells in danger (either on or off the property)?
h. Now much reached surface waters?
a. During normal business hours call your DWQ regional office; Phone #, After hou-�
emergency number: [phone]. Your phone call should include: your name, fftacil
number, telephone number, the details of the incident from item 2 above, tthe
location of the facility, the location or direction of the movement of the spill, weather a•
d t vWnd conditions. The corrective measures that have been under taken, an
seriousness of the situation.
b. If the spill leaves property or enters surface waters, call local EMS phone number.
c. Instruct EMS to contact local Health Department
d. Contact CE's phone number, local SWCD office phone number and the local NRCS
office for advice / technical assistance phone number.

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)
"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.
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).

V. Provisions for Safety Measures
Anaerobic Digester System O&M Page 11 of 16

A. Restriction of Access: No persons should enter any portion of the wastewater treatment system
unless performing a repair or routine maintenance, and only then if accompanied by another
person capable of performing life-saving activities should the need arise. No person should Enter
a waste collection pit, pump station well, or any portion of the anaerobic digester unless all
accumulated biogas has been removed via venting or other utilization and sufficient airflow has
been directed to the workspace via fans, blowers, or other means. Personal safety is the
responsibility of the person or organization conducting the work, and not specifically the
responsibility of the farm owner or other associated equipment providers or construction
contractors.
B. Emergency Contacts: Information shall be posted at the gate and in the control room. (There
will be no harmful chemicals used for the anaerobic digestion system).
C. All equipment safety guards, warning labels, safeties, and warning alarms shall be kept in place
and operational at all times.
D. Keep and maintain all clearances as recommended by equipment manufacturers and as required
by law.
E. Keep all open flames and sources of combustion away from gas accumulations. Do not smoke
near the gas collection, conveyance, or combustion components. It is recommended that any
combustion source or open flame be kept to a minimum separation distance of 50 ft from the
anaerobic digester cover.
VI. Spill Prevention and Control Provisions
A. Response to Upsets and Bypasses Including Control Containment and Remediation: Audible
alarms will be provided at all controls stations. The Control System will provide remote alarms
to alert operator of a problem should one occur.
B. Contact Information for Operational Personnel, Emergency Responders, and Regulatory
Agencies: Phone numbers for Emergency Responders and Remediation Agency numbers will be
located by the computers and control systems in the control room.
C. Facility Control Valves will allow operator to isolate Systems if a problem occurs.
