Subject: Jim Grady and Sons, Inc.—
Facility # AWS310185
State Digester General Permit
Dear Ms. Lawson,
CAVANAU G H
Stewards.
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 Jim Grady and Sons, Inc. 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.
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.
The applicable setbacks (per the 'Swine Farm Siting Act') for the proposed digester are shown on sheet
C.2.4.3 of the engineering plans, which indicates that the digester will be greater than 100' from all
wetlands, greater than 1,500' from all occupied residences, and greater than 2,500' from all schools,
hospitals, churches, outdoor recreational facilities, national parks, State Parks, and child care centers;
regarding the setback from adjacent property boundaries, the existing swine houses are approx. 88'
from the property line to the south, and the proposed digester will be approx. 118' from the same
property line, so the proposed digester meets the requirements of NCGS 106-806(e)(3) since the
digester will not be "located closer to the... property" than the existing swine houses.
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 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.
Cavanaugh &Associates, P.A. PO Box 11197 Winston-Salem, NC27116,1-877-557-8923, www.covanoughsolutions.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, 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.
Please do not hesitate to contact our office should you have any questions, comments, or require any
additional information.
Regards,
Cavanaugh & Associates, P.A.

Narrative
'Jim Grady and Sons, Inc.' will utilize existing barns with slotted floors over flushing pits to collect
manure.
Upon flushing, Barns 1-8 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. 970 gpm (1 pump)
through an 8" HDPE (DR 17) forcemain into the anaerobic digester.
After treatment in the anaerobic digester (309,768 cubic feet of total volume, 247,310 cubic feet at
Operating Level), the effluent will enter the Level Control Station (LC). The Level Control Station will
utilize two 10 hp GEA pumps, with a typical flow of approx. 490 gpm through a 6" HDPE (DR 17)
forcemain to the existing Lagoon.

September 25, 2019
Subject: Certificate of Coverage No. AWS310185
Jim Grady and Sons, Inc.
Swine Waste Collection, Treatment,
Storage and Application System
Duplin County
In accordance with your renewal request and a notification of change of ownership, we are hereby
forwarding to you this Certificate of Coverage (COC) issued to Michele T Grady, authorizing the operation
of the subject animal waste management system in accordance with General_Permit AWG100.000. Please
read this COC and the enclosed State General Permit carefully.
This approval shall consist of the operation of this system including, but not limited to, the management
and land application of animal waste as specified in the facility's Certified Animal Waste Management Plan
(CAWMP) for Jim Grady and Sons, Inc., located in Duplin County, with a swine animal capacity of no
greater than the following annual averages:
Wean to Finish: Feeder to Finish: 7040 Boar/Stud:
Wean to Feeder: Farrow to Wean: Gilts:
Farrow to Finish: Farrow to Feeder: Other:
If this is a Farrow to Wean or Farrow to Feeder operation, there may be one boar for each 15 sows. Where
boars are unnecessary, they may be replaced by an equivalent number of sows. Any of the sows may be
replaced by gilts at a rate of 4 gilts for every 3 sows.
This COC shall be effective from October 1, 2019 until September 30, 2024 and shall hereby void
Certificate of Coverage Number AWS310185 that was previously issued to this facility. Pursuant to this
COC, you are authorized and required to operate the system in conformity with the conditions and
limitations as specified in the General Permit, the facility's CAWMP, and this COC. An adequate system
for collecting and maintaining the required monitoring data and operational information must be established
for this facility. Any increase in waste production greater than the certified design capacity or increase in
number of animals authorized by this COC (as provided above) will require a modification to the CAWMP
and this COC and must be completed prior to actual increase in either wastewater flow or number of animals.
You are encouraged to update your Swine Odor Control Checklist using the enclosed form. If you do so,
you must send a copy of the updated form to the Animal Feeding Operations Program at the address below.
Please pay careful attention to the record keeping and monitoring conditions in this permit. Stocking and
Mortality Form (STOCK-1) has been updated, all other record keeping forms are unchanged with this
General Permit. Please use the most current record kegVing forms.

WASTE UTILIZATION PLAN
Goldsboro Hog Farms, Inc.
Thursday, September 1, 2011 Updated: 91112011
Producer: Michele T. Grady
Farm Name: Jim Grady & sons Inc.
P.O. Box 428
Faison,NC 28341
Telephone # : [phone]
Type of Operation : Feeder to Finish Swine
Number of Animals : 7040 hogs design capacity
Application Method: Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent
pollution of surface and/or groundwater. The plant nutrients in the animal waste should be
used to reduce the amount of commercial fertilizer required for the crops in the fields where
waste is to be applied. This waste utilization plan uses nitrogen as the limiting nutrient.
Waste should be analyzed before each application cycle. Annual soil tests are strongly
encouraged so that all plant nutrients can be balanced for realistic yields of the crop to be
grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe
manner. Always apply waste based on the needs of the crop to be grown and the nutrient
contents of the waste. Do not apply more nitrogen than the crop can utilize. Soil types are
important as they have different infiltration rates, leaching potentials, cation exchange
capacities, and avaialable water holding capacities. Normally waste shall not be applied to
land eroding at greater than 5 tons per acre per year. With special pre -cautions, waste may
be applied to land eroding at up to 10 tons per acre per year. Do not apply waste on
saturated soils, when it is raining, or when the surface is frozen. Either of these conditions
may result in runoff to surface waters which is not allowed under DEM regulations. Wind
conditions should also be considered to avoid drift and downwind odor problems. To
maximize the value of the nutrients for crop production and to reduce the potential for
pollution, the waste should be applied to a growing crop or applied to bare ground not more
than 30 days prior to planting. Injecting the waste or disking will conserve nutrients and
reduce odor problems. This plan is based on waste application through irrigation for this is
the manner in which you have chosen to apply your waste. If you choose to inject the waste
in the future, you need to revise this plan. Nutrient levels for injecting waste and irrigating
waste are not the same.
The estimated acres needed to apply the animal waste is based on typical nutrient content for
this type of facility. Acreage requirements should be based on the waste analysis report from
your waste management facility. Attached you will find information on proper sampling
techniques, preparation, and transfer of waste samples to the lab for ananlysis. This waste
utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
2H.0217 adopted by the Environmental Management Commission.

7040 hogs X 2.3 Ibs PAN/hogs/year = 16192 PAN/year
Applying the above amount of waste is a big job. You should plan time and have appropriate
equipment to apply the waste in a timely manner.
The following acreage will be needed for waste application based on the crop to be grown,
soil type and suface application.

Acres show in each of the preceeding tables are considered to be the usable acres excluding
required buffers, filter strips along ditches, odd areas unable to be irrigated, and perimeter
areas not receiving full application rates due to equipment limitations. Actual total acres in the
fields listed may, and most likely will be, more than the acres shown in the tables.
NOTE: The Waste Utilization Plan must contain provisions for periodic land application of
sludge at agronomic rates. The sludge will be nurturient rich and will require precautionary
measures to prevent over application of nutrients or other elements. Your production facility
will produce approximately 2604.8 pounds of plant available nitrogen (PAN) per year in the
sludge that will need to be removed on a periodic basis. This figure is PAN when
broadcasting the sludge. Please be aware that additional acres of land, as well special
equipment, may be needed when you remove this sludge.
See the attached map showing the fields to be used for the utilization of wastewater.
APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not exceed the intake rate of the soil at the time of
irrigation such that runoff or ponding occurs. This rate is limited by initial soil moisture
content, soil structure, soil texture, water droplet size, and organic solids. The application
amount should not exceed the available water holding capacity of the soil at the time of
irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of the
crop.
Your facility is designed for 180 days of temporary storage and the temporary storage must
be removed on the average of once every 5.92 months. In no instance should the volume of
waste being stored in your structure be within 1.58 feet of the top of the dike.
If surface irrigation is the method of land application for this plan, it is the responsiblity of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in Tables 1 and 2. Failure to apply the recommended rates and
amounts of Nitrogen shown in -the tables may make this plan invalid.
The following table is provided as a guide for establishing application rates and amounts.

NARRATIVE OF OPERATION
WUP was ammended and updated 9/1/11. All information was provided by Grower and plan
that was written by Billy Houston. This plan is written based on an Irrigation Design done by
Billy Hall.
A small grain can be used by the Grower as green manure cover crop before corn. The 30
Ibs for green maure will be removed from the corn crop for that year

PLANS & SPECIFICATIONS
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 which reaches surface water is prohibited. Illegal discharges are subject
to assessment of civil penalties of $10,000 per day by the Division of Water Quality for every
day the discharge continues.
2. The Field Office must have documentation in the design folder that the producer either
owns or has long term access to adequate land to properly dispose of waste. If the producer
does not own adequate land to properly dispose of waste, he shall provide NRCS with a copy
of a written agreement with a landowner who is within a reasonable proximity, allowing
him/her the use of the land for waste application for the life expectancy of the production
facility. It is the responsibility of the owner of the facility to secure an update of the Waste
Utilization Plan when there is a change in the operation, increase in the number of animals,
method of utilization, or available land.
3. Animal waste shall be applied to meet, but not exceed, the Nitrogen needs for realistic crop
yields based on soil type, available moisture, historical data, climate conditions, and level of
management, unless there are regulations that restrict the rate of application for other
nutrients.
4. Animal waste may be applied to land that has a Resource Management System (RMS) or
an Alternative Conservation System (ACS). If an ACS is used the soil loss shall' be no greater
than 10 tons per acre per year and appropriate filter strips will be used where runoff leaves
the field. These filter strips will be in addition to 'Buffers" required by DEM. (See FOTG
Stantard 393 - Filter Strips and Standard 390 Interim Riparian Forest Buffers).
5. Odors can be reduced by injecting the waste or disking after waste application. Waste
should not be applied when there is danger of drift from the irrigation field.
6. When animal waste is to be applied on acres subject to flooding, it will be soil incorporated
on conventionally tilled cropland. When 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" in the NRCS Technical Reference -
Environment file for guidance.)
*7. Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that runoff
does not occur offsite or to surface waters and in a method which does not cause drift from
the site during application. No ponding should occur in order to control conditions conducive
to odor or flies and to provide uniformity of application.
8. Animal waste shall not be applied to saturated soils, during rainfall events, or when the
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.
10. Waste nutrients 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 a crop on bare soil.
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
Page 7

and from any perennial stream or river (other that an irrigation ditch or canal. Animal waste
other than swine waste from facilities sited on or after October 1, 1995), shall not be applied
closer than 25 feet to perennial waters. (See Standard 393 - Filter Strips)
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 landownwer.
14. Waste shall be applied in a manner not to reach other property and public right - of ways.
15. Animal waste shall not be discharged into surface waters, drainageways, or wetlands by
discharge or by over -spraying. Animal waste may be applied to prior converted croplands
provided they have been approved as a land application site by a "technical specialist".
Animal waste should not be applied on grassed waterways that discharge directly into water
courses, except when applied at agronomic rates and the application 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 'embaHkments, berms, pipe -runs, etc.). If needed; special vegetation shall be
provided for these areas and 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. Lagoon 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 as a preemergence with no other 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 fpr waste storage ponds.
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
element. 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 for
optimum crop production amd maintained. Soil and waste analysis records shall be kept for
five (5) years. Poultry dry waste application records shall be maintained for three (3) 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 Department of
Page 8

Agriculture regulations.
* Liquid Systems

This plan will be implemented in the event that wastes from your operation are leaking,
overflowing or running of( site. You should not wait until wastes reach surface waters or
leave your property to consider that you have a problem. You should make every effort to
ensure that this does not happen. This plan should be posted in an accessible location
for all employees at the facility. The following are some action items you should take.
1. Stop the release of wastes. Depending on the situation, this may or may not be possible. Suggested
responses to some possible problems are listed below.
A. Lagoon overflow - possible solutions are:
a) Add soil to berm to increase elevation of dam.
b) Pump wastes to fields at an acceptable rate.
C) Stop all flow to the lagoon immediately.
d) Call a pumping contractor.
e) Make sure no surface water is entering lagoon.
B. Runoff from waste application field -actions include:
a) Immediately stop waste application.
b) Create a temporary diversion to contain waste.
c) Incorporate waste to reduce runoff.
d) Evaluate and eliminate the reason(s) that cause the runoff.
e) Evaluate the application rates for the fields where runoff occurred.
C. Leakage from the waste pipes and sprinklers - action include:
a) Stop recycle pump.
b) 5top irrigation pump.
C) Close valves to eliminate further discharge.
d) Repair all leaks prior to restartfig pumps.
D. Leakage from flush systems, houses, solid separators - action include:
a) Stop re yde pump.
b) Stop irrigation pump.
C) Make sure siphon occurs.
d) Stop all flow in the house, flush systems, or said separators.
E. Leakage from base or sidewall of lagoon. Often this is seepage as opposed to flowing leaks -
possible action:
a) Dig a small sump or ditch from the embankment to catch all seepage, put in a submersible
pump, and pump back to lagoon.
b) If holes are caused by burrowing animals, trap or remove ardmals and fill holes and
compact with a day type soil.
C) Have a professional evaluate the condition of the side walls and the lagoon bottom as soon
as possible.

2. Assess the extent of the spill and note any obvious damages.
a. Did the waste reach surface waters?
b. Approximately how much was released and for what duration?
c. Any damage notes, such as employee injury, fish kills, or property damage?
d. Did the spill leave the property'?
e. Does the spill have the potential to reach surface waters?
f. Could a future rain event cause the spill to reach surface waters?
g. Are potable water wells in danger (either on or off the property)?
h. How much reached surface waters?
3. Contact appropriate agencies.
a. During normal business hours call your DWQ regional office; Phone #, After hours,
emergency number. [phone]. Your phone call should include: your name, facility
number, telephone number, the details of the incident from item 2 above, the exact
location of the facility, the location or direction of the movement of the spill, weather and
wind conditions. The corrective measures that have been under taken, and the
seriousness of the situation.
b. If the spill leaves property or enters surface waters, call local EMS phone number.
c. Instruct EMS to contact local Health Department
d. Contact CE's phone number, local SWCD office phone number and the local NRCS
office for advice 1 technical assistance phone number.
4. If none of the above works call 911 or the Sheriffs Department and explain your problem to
them and ask the person to contact the proper agencies for you.
5. Contact the contractor of your choice to begin repair or problem to minimize offsite damage.
a. Contractors Name: J oi� h jZ11 ('! , a k
b. Contractors Address: Ko r.& ws G I tTc---
c. Contractors Phone: qtb im,a ol51
6. Contact the technical specialist who certified the lagoon (MRCS, Consulting Engineer, etc.)
a. Name: p o AAayyfi
b. Phone:
7. Implement procedures as- advised by iiWQ and technical assistance agencies to rectify the
damage, repair the system, and reassess the waste management plan to keep problems
with release of wastes from happening again.

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 Di -er ster -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 (CO2).
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 0&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 3d 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 2"d 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 3" party, but the information is included in this 0&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).
