Cavanaugh & Associates, P.A., on behalf of the farm owner, hereby submi MI
NCDEQ Division of Water Resources for review of the State Digest ener "nt n99 � application
oln package
fore
for Bowles & Son Farm #1. The subject project is located in Duplin County, Noth�Ca olina. g
To facilitate your review of the enclosed documentation, the following is an itemized breakdown:
I. 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.
As marked in the 'State Digester General Permit Application' application form attached with this
package, Section 3.3 of the form has not been filled out because there are no proposed swine
treatment/storage structures for this project; one of the existing lagoons will be converted to an
anaerobic digester.
Please note that the Surface Water Classification (Section 7 of the application) has been submitted to
the appropriate regional DWR office (or will be in the near future), and we expect to forward that
approval to you in the next few weeks.
Please do not hesitate to contact our office should you have any questions, comments, or require any
additional information.
Regards,

Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface water and/or groundwater. The plant nutrients in the animal waste should be used
to reduce the amount of commercial fertilizer required for the crops in the fields where the waste
is to be applied.
This waste utilization plan uses nitrogen as the limiting nutrient. Waste should be analyzed
before each application cycle. Annual soil tests are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe manner:
1. Always apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can utilize.
2. Soil types are important as they have different infiltration rates, leaching potentials,
cation exchange capacities, and available water holding capacities.
3. Normally waste shall be applied to land eroding at less than 5 tons per acre per
year. Waste may be applied to land eroding at 5 or more tons per acre annually, but
less than 10 tons per acre per year providing that adequate filter strips are established.
4. Do not apply waste on saturated soils, when it is raining, or when the surface is frozen.
Either of these conditions may result in runoff to surface waters which is not allowed
under DWR regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor
problems.
6. To maximize the value of the nutrients for crop production and to reduce the potential
for pollution, the waste should be applied to a growing crop or applied not more than
30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or
disking will conserve nutrients and reduce odor problems.
1 of 11
This plan is based on the waste application method shown above. If you choose to change
methods in the future, you need to revise this plan. Nutrient levels for different application
methods are not the same.
The estimated acres needed to apply the animal waste is based on typical nutrient content
for this type of facility. In some cases you may want to have plant analysis made, which could
allow additional waste to be applied. Provisions shall be made for the area receiving waste to
be flexible so as to accommodate changing waste analysis content and crop type. Lime must
be applied to maintain pH in the optimum range for specific crop production.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
21-1.0217 adopted by the Environmental Management Commission.

This plan does not include commercial fertilizer. The farm should produce adequate plant
available nitrogen to satisfy the requirements of the crops listed above.
The applicator is cautioned that P and K may be over applied while meeting the N requirements.
In the future, regulations may require farmers in some parts of North Carolina to have a nutrient
management plan that addresses all nutrients. This plan only addresses nitrogen.
In interplanted fields ( i.e. small grain, etc, interseeded in bermuda), forage must be removed
through grazing, hay, and/or silage. Where grazing, plants should be grazed when they
reach a height of six to nine inches. Cattle should be removed when plants are grazed to a
height of four inches. In fields where small grain, etc, is to be removed for hay or silage, care
should be exercised not to let small grain reach maturity, especially late in the season (i.e.
April or May). Shading may result if small grain gets too high and this will definitely interfere
with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen
being utilized. Rather than cutting small grain for hay or silage just before heading as is
the normal situation, you are encouraged to cut the small grain earlier. You may want to
consider harvesting hay or silage two to three times during the season, depending on the
time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

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

The waste utilization plan must contain provisions for periodic land application of sludge at
agronomic rates. The sludge will be nutrient rich and will require precautionary measures to
prevent over application of nutrients or other elements. Your production facility will produce
approximately 2496.96 pounds of plant available nitrogen per year and will accumulate in the lagoon
sludge based on the rates of accumulation listed above.
If you remove the sludge every 5 years, you will have approximately 12484.8 pounds of plant
available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 41 acreas of land. If you apply the sludge
to corn at a rate of 125 pounds per acre, you will need 99.8784 acres of land. Please note that these
are only estimates of the PAN produced and the land required to utilize that PAN. Actual values
may only be determined by sampling the sludge for plant available nitrogen content prior to application
Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific
application fields designated for sludge application at time of removal.
APPLICATION OF WASTE BY IRRIGATION:
The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation
such that runoff or ponding occurs. This rate is limited by initial soil moisture content, soil
structure, soil texture, water droplet size, and organic solids. The application amount should not
exceed the available water holding capacity of the soil at the time of irrigation nor should the
plant available nitrogen applied exceed the nitrogen needs of the crop.
If surface irrigation is the method of land application for this plan, it is the responsibility of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in the preceding table. Failure to apply the recommended rates and
amounts of nitrogen shown in the tables may make this plan invalid.
*This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. In many situations, the application
amount shown cannot be applied because of the nitrogen limitation. The maximum
application amount shown can be applied under optimum soil conditions.
Your facility is designed for >180 days of temporary storage and the temporary storage must
be removed on the average of once every 6 months. In no instance should the volume of the
waste stored in your structure be within the 25 year 24 hour storm storage or one foot of
freeboard except in the event of the 25 year 24 hour storm.
It is the responsibility of the producer and waste applicator to ensure that the spreader equipment
is operated properly to apply the correct rates to the acres shown in the tables. Failure to apply
the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid.
Call your technical specialist after you receive the waste analysis report for assistance in
determining the amount of waste per acre and the proper application prior to applying the waste.

Additional Comments:
This plan revised 8/24/2022 to reflect the updating of the production and
application rates to match those currently listed on the NCSU Nutrient
Management website and to include the addition of pull 10 and pivot 2.
This plan revised 2/20/2023 to reflect the inclusion of subfield acres and a crop
change from berm udagrass with overseed to a corn, wheat and soybean
rotation for fields and subfields of Pivot 1, 6A and 6B. All other parameters
remained the same as in the previous plan dated 8/24/2022.
Any/all fields listed as "Optional Fields" are not required to be in any of the
crops listed in this plan unless they are actively being 2221ied to or will be
applied to.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
Animal waste shall not reach surface waters of the state by runoff, drift, manmade
conveyances, direct application, or direct discharge during operation or land application.
Any discharge of waste which reaches surface water is prohibited.
2 There must be documentation in the design folder that the producer either owns or has an
agreement for use of adequate land on which to properly apply the waste. If the producer
does not own adequate land to properly dispose of the waste, he/she shall provide
evidence of an agreement with a landowner, who is within a reasonable proximity,
allowing him/her the use of the land for waste application. It is the responsibility of the
owner of the waste production facility to secure an update of the Nutrient Utilization Plan
when there is a change in the operation, increase in the number of animals, method of
application, recieving crop type, or available land.
Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic
crop yields based upon soil type, available moisture, historical data, climatic conditions,
and level of management, unless there are regulations that restrict the rate of applications
for other nutrients.
4 Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land eroding at more than 5 tons per acre per year but less than 10 tons
per acre per year provided grass filter strips are installed where runoff leaves the field
(See USDA, NRCS Field Office Technical Guide Standard 393 - Filter Strips).
Odors can be reduced by injecting the waste or disking after waste application. Waste
should not be applied when there is danger of drift from the land application field.
6 When animal waste is to be applied on acres subject to flooding, waste will be soil
incorporated on conventionally tilled cropland. When waste is applied to conservation tilled
crops or grassland, the waste may be broadcast provided the application does not occur
during a season prone to flooding (See "Weather and Climate in North Carolina" for
guidance).
7 Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that runoff
does not occur offsite or to surface waters and in a method which does not cause drift
from the site during application. No ponding should occur in order to control odor and
flies.
8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the
surface is frozen.
9of11
NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
Animal waste shall be applied on actively growing crops in such a manner that the crop is not
covered with waste to a depth that would inhibit growth. The potential for salt damage from
animal waste should also be considered.
10 Nutrients from waste shall not be applied in fall or winter for spring planted crops on soils with a
high potential for leaching. Waste/nutrient loading rates on these soils should be held to a
minimum and a suitable winter cover crop planted to take up released nutrients. Waste shall
not be applied more than 30 days prior to planting of the crop or forages breaking dormancy,
11 Any new swine facility sited on or after October 1, 1995 shall comply with the following: The
outer perimeter of the land area onto which waste is applied from a lagoon that is a component of
a swine farm shall be at least 50 feet from any residential property boundary and canal. Animal
waste, other than swine waste from facilities sited on or after October 1, 1995, shall not be
applied closer than 25 feet to perennial waters.
12 Animal waste shall not be applied closer than 100 feet to wells.
13 Animal waste shall not be applied closer than 200 feet of dwellings other than those owned by
the landowner.
14 Waste shall be applied in a manner not to reach other property and public right-of-ways.
15 Animal waste shall not be discharged into surface waters, drainageways, or wetlands by discharge
or by over -spraying. Animal waste may be applied to prior converted cropland provided the fields
have been approved as a land application site by a "technical specialist". Animal waste shall not
be applied on grassed waterways that discharge directly into water courses, and on other grassed
waterways, waste shall be applied at agronomic rates in a manner that causes no runoff or drift
from the site.
16 Domestic and industrial waste from washdown facilities, showers, toilets, sinks, etc., shall not be
discharged into the animal waste management system.
10of11
NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
17 A protective cover of appropriate vegetation will be established on all disturbed areas (lagoon
embankments, berms, pipe runs, etc.). Areas shall be fenced, as necessary, to protect the
vegetation. Vegetation such as trees, shrubs, and other woody species, etc., are limited to areas
where considered appropriate. lagoon areas should be kept mowed and accessible. Berms and
structures should be inspected regularly for evidence of erosion, leakage, or discharge.
18 If animal production at the facility is to be suspended or terminated, the owner is responsible for
obtaining and implementing a "closure plan" which will eliminate the possibility of an illegal
discharge, pollution and erosion.
19 Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular basis to
prevent breakdowns, leaks and spills. A regular maintenance checklist should be kept on site.
20 Animal waste can be used in a rotation that includes vegetables and other crops for direct human
consumption. However, if animal waste is used on crops for direct human consumption, it should
only be applied pre -plant with no further applications of animal waste during the crop season.
21 Highly visible markers shall be installed to mark the top and bottom elevations of the temporary
storage (pumping volume) of all waste treatment lagoons. Pumping shall be managed to
maintain the liquid level between the markers. A marker will be required to mark the maximum
storage volume for waste storage ponds.
22 Waste shall be tested within 60 days of utilization and soil shall be tested at least once every three
yeares at crop sites where waste products are applied. Nitrogen shall be the rate -determining
nutrient, unless other restrictions require waste to be applied based on other nutrients, resulting
in a lower application rate than a nitrogen based rate. Zinc and copper levels in the soil shall be
monitored and alternative crop sites shall be used when these metals approach excessive levels.
pH shall be adjusted and maintained for optimum crop production. Soil and waste analysis
records shall be kept for a minimum of five years. Poultry dry waste application records shall be
maintained for a minimum of three years. Waste application records for all other waste shall be
maintained for a minimum of five years.
23 Dead animals will be disposed of in a manner that meets North Carolina regulations.

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

OPERATION & MAINTENANCE PLAN
Proper lagoon management should be a year-round priority. It is especially important to manage
levels so that you do not have problems during extended rainy and wet periods.
Maximum storage capacity should be available in the lagoon for periods when the receiving crop is
dormant (such as wintertime for bermudagrass) or when there are extended rainy spells such as a
thunderstorm season in the summertime. This means that at the first sign of plant growth in the
later winter / early spring, irrigation according to a farm waste management plan should be done
whenever the land in dry enough to receive lagoon liquid. This will make storage space available in
the lagoon for future wet periods. In the late summer / early fall the lagoon should be pumped down
to the low marker (see Figure 2-1) to allow for winter storage. Every effort should be made to
maintain the lagoon close to the minimum liquid level as long as the weather and waste utilization
plan will allow it.
Waiting until the lagoon has reached its maximum storage capacity before starting to irrigated does
not leave room for storing excess water during extended wet periods. Overflow from the lagoon for
any reason except a 25-year, 24-hour storm is a violation of state law and subject to penalty action.
The routine maintenance of a lagoon involves the following:
Maintenance of a vegetative cover for the dam. Fescue or common bermudagrass
are the most common vegetative covers. The vegetation should be fertilized each
year, if needed, to maintain a vigorous stand. The amount of fertilized applied
should be based on a soils test, but in the event that it is not practical to obtain a
soils test each year, the lagoon embankment and surrounding areas should be
fertilized with 800 pounds per acre of 10-10-10, or equivalent.
Brush and trees on the embankment must be controlled. This may be done by
mowing, spraying, grazing, chopping, or a combination of these practices. This
should be done at least once a year and possibly twice in years that weather
conditions are favorable for heavy vegetative growth.
NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter the lagoon
water. Such chemicals could harm the bacteria in the lagoon that are treating the waste.
Maintenance inspections of the entire lagoon should be made during the initial filling of the lagoon
and at least monthly and after major rainfall and storm events. Items to be checked should include,
as a minimum, the following:
Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes -- look for:
1. separation of joints
2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes
2
Lagoon surface -- look for:
1. undesirable vegetative growth
2. floating or lodged debris
Embankment -- look for:
1. settlement, cracking, or "jug" holes
2. side slope stability -- slumps or bulges
3. wet or damp areas on the back slope
4. erosion due to lack or vegetation or as a result of wave action
5. rodent damage
Larger lagoons may be subject to liner damage due to wave action caused by strong
winds. These waves can erode the lagoon sidewalls, thereby weakening the lagoon dam.
A good stand of vegetation will reduce the potential damage caused by wave action. If
wave action causes serious damage to a lagoon sidewall, baffles in the lagoon may be
used to reduce the wave impacts.
Any of these features could lead to erosion and weakening of the dam. If your lagoon
has any of these features, you should call an appropriate expert familiar with design and
construction of waste lagoons. You may need to provide a temporary fix if there is a
threat of a waste discharge. However, a permanent solution should be reviewed by the
technical expert. Any digging into a lagoon dam with heavy equipment is a serious
undertaking with potentially serious consequences and should not be conducted unless
recommended by an appropriate technical expert.
Transfer Pumps -- check for proper operation of:
1. recycling pumps
2. irrigation pumps
Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding
noise, or a large amount of vibration, may indicate that the pump is in need of repair or
replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that
you are not completely "surprised" by equipment failure. You should perform your
pumping system maintenance at a time when your lagoon is at its low level. This will
allow some safety time should major repairs be required. Having a nearly full lagoon is
not the time to think about switching, repairing, or borrowing pumps. Probably, if your
lagoon is full, your neighbor's lagoon is full also. You should consider maintaining an
inventory of spare parts or pumps.
Surface water diversion features are designed to carry all surface drainage
waters (such as rainfall runoff, roof drainage, gutter outlets, and parking lot
runoff) away from your lagoon and other waste treatment or storage
structures. The only water that should be coming from your lagoon is that
which comes from your flushing (washing) system pipes and the rainfall that
hits the lagoon directly. You should inspect your diversion system for the
following:
1. adequate vegetation
2. diversion capacity
3. ridge berm height
Identified problems should be corrected promptly. It is advisable to inspect your system
during or immediately following a heavy rain. If technical assistance is needed to
determine proper solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then
record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will
give you an idea of how much your lagoon level will rise with a certain rainfall amount
(you must also be recording your rainfall for this to work). Knowing this should help in
planning irrigation applications and storage. If your lagoon rises excessively, you may
have an overflow problem from a surface water diversion or there may be seepage into
the lagoon from the surrounding land.
Lagoon Operation
Startup:
1. Immediately after construction establish a complete sod cover on bare soil
surfaces to avoid erosion.
2. Fill new lagoon design treatment volume at least half full of water before waste
loading begins, taking care not to erode lining or bank slopes.
3. Drainpipes into the lagoon should have a flexible pipe extender on the end of the
pipe to discharge near the bottom of the lagoon during initial filling or another
means of slowing the incoming water to avoid erosion of the lining.
4. When possible, begin loading new lagoons in the spring to maximize bacterial
establishment (due to warmer weather).
5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon liquid
volume. This seeding should occur at least two weeks prior to the addition of
wastewater.
6. Maintain a periodic check on the lagoon liquid pH. If the pH falls below 7.0, add
agricultural lime at the rate of 1 pound per 1000 cubic feet of lagoon liquid volume
until the pH rises above 7.0. Optimum lagoon liquid pH is between 7.5 and 8.0.
7. A dark color, lack of bubbling, and excessive odor signals inadequate biological
activity. Consultation with a technical specialist is recommended if these
conditions occur for prolonged periods, especially during the warm season.
Loading:
The more frequently and regularly that wastewater is added to a lagoon, the better the
lagoon will function. Flush systems that wash waste into the lagoon several times daily
are optimum for treatment. Pit recharge systems, in which one or more buildings are
drained and recharged each day, also work well.
• Practice water conservation --- minimize building water usage and spillage from
leaking waterers, broken pipes and washdown through proper maintenance and water
conservation.
• Minimize feed wastage and spillage by keeping feeders adjusted. This will reduce the
amount of solids entering the lagoon.
Management:
• Maintain lagoon liquid level between the permanent storage level and the full
temporary storage level.
• Place visible markers or stakes on the lagoon bank to show the minimum liquid level
and the maximum liquid level. (Figure 2-1).
• Start irrigating at the earliest possible date in the spring based on nutrient
requirements and soil moisture so that temporary storage will be maximized for the
summer thunderstorm season. Similarly, irrigate in the late summer / early fall to
provide maximum lagoon storage for the winter.
• The lagoon liquid level should never be closer than 1 foot to the lowest point of the
dam or embankment.
• Don not pump the lagoon liquid level lower than the permanent storage level unless
you are removing sludge.
• Locate float pump intakes approximately 18 inches underneath the liquid surface and
as far away from the drainpipe inlets as possible.
• Prevent additions of bedding materials, long-stemmed forage or vegetation, molded
feed, plastic syringes, or other foreign materials into the lagoon.
• Frequently remove solids from catch basins at end of confinement houses or
wherever they are installed.
• Maintain strict vegetation, rodent, and varmint control near lagoon edges.
• Do not allow trees or large bushes to grow on lagoon dam or embankment.
• Remove sludge from the lagoon either when the sludge storage capacity is full or
before it fills 50 percent of the permanent storage volume.
• If animal production is to be terminated, the owner is responsible for obtaining and
implementing a closure plan to eliminate the possibility of a pollutant discharge.
Sludge Removal:
Rate of lagoon sludge buildup can be reduced by:
5
• proper lagoon sizing,
• mechanical solids separation of flushed waste,
• gravity settling of flushed waste solids in an appropriately designed basin, or
• minimizing feed wastage and spillage.
Lagoon sludge that is removed annually rather than stored long term will:
• have more nutrients,
• have more odor, and
• require more land to properly use the nutrients.
Removal techniques:
• Hire a custom applicator.
• Mix the sludge and lagoon liquid with a chopper - agitator impeller pump through large -
bore sprinkler irrigation system onto nearby cropland; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland; mix
remaining sludge; pump into liquid sludge applicator; haul and spread onto cropland or
forageland; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland;
dredge sludge from lagoon with dragline or sludge barge; berm an area beside lagoon
to receive the sludge so that liquids can drain back into lagoon; allow sludge to
dewater; haul and spread with manure spreader onto cropland or forageland; and soil
incorporate.
Regardless of the method, you must have the sludge material analyzed for waste
constituents just as you would your lagoon water. The sludge will contain different
nutrient and metal values from the liquid. The application of the sludge to fields will be
limited by these nutrients as well as any previous waste applications to that field and crop
requirement. Waste application rates will be discussed in detail in Chapter 3.
When removing sludge, you must also pay attention to the liner to prevent damage.
Close attention by the pumper or drag -line operator will ensure that the lagoon liner
remains intact. If you see soil material or the synthetic liner material being disturbed, you
should stop the activity immediately and not resume until you are sure that the sludge can
be removed without liner injury. If the liner is damaged it must be repaired as soon as
possible.
Sludge removed from the lagoon has a much higher phosphorus and heavy metal content
than liquid. Because of this it should probably be applied to land with low phosphorus and
metal levels, as indicated by a soil test, and incorporated to reduce the chance of erosion.
Note that if the sludge is applied to fields with very high soil -test phosphors, it should be
applied only at rates equal to the crop removal of phosphorus. As with other wastes,
always have your lagoon sludge analyzed for its nutrient value.
6
The application of sludge will increase the amount of odor at the waste application site.
Extra precaution should be used to observe the wind direction and other conditions which
could increase the concern of neighbors.
Possible Causes of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure.
Types of failures include leakage through the bottom or sides, overtopping, and breach of
the dam. Assuming proper design and construction, the owner has the responsibility for
ensuring structure safety. Items which may lead to lagoon failures include:
• Modification of the lagoon structure -- an example is the placement of a pipe in the dam
without proper design and construction. (Consult an expert in lagoon design before
placing any pipes in dams.)
• Lagoon liquid levels — high levels are a safety risk.
• Failure to inspect and maintain the dam.
• Excess surface water flowing into the lagoon.
• Liner integrity — protect from inlet pipe scouring, damage during sludge removal, or
rupture from lowering lagoon liquid level below groundwater table.
NOTE: If lagoon water is allowed to overtop the dam, the moving water will soon cause
gullies to form in the dam. Once this damage starts, it can quickly cause a large
discharge of wastewater and possible dam failure.

Mortality Management Methods
Indicate which method(s) will be implemented.
When selecting multiple methods indicate a primary versus secondary option.
Methods other than those listed must be approved by the State Veterinarian.
Primary Secondary Routine Mortality
a Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal
death. The burial must be at least 300 feet from any flowing stream or public body of water
(G.S.1O6-403). The bottom of the burial pit should be at least one foot above the seasonal
high water table. Attach burial location map and plan.
Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC
13B .0200.
Rendering at a rendering plant licensed under G.S. 106-168.7,
Complete incineration according to 02 NCAC 52C .0102.
A composting system approved and permitted by -the NC Department of Agriculture & Con-
sumer Services Veterinary Division (attach copy of permit). if compost is distributed off -farm,
additional requirements must be met and a permit is required from NC DEQ.
a In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture & Consumer Services (G.S. 106-549.70).
Any method which, in the professional opinionjof the State Veterinarian, would make possible
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).
• In the event of imminent threat of a disease emergency, the State Veterinarian may enact
additional temporary procedures or measures for disposal according to G.S. 106-399.4.

I. 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 (CO2).
Anaerobic Digester System 0&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.
111. 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 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 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 3`d 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 0&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 0&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).
