The waste from your animal facility must be land applied at a specified rate to prevent
P'?llution 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.
~his 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 the 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 not be applied to land eroding at more than 5 tons per acre per
year. Wa st e may be applied to land eroding at 5 or more tons per acre annually, but
les s 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 in runoff to the surface water s which is not
allowed under DWQ regulations.
5. Wind conditions should also be considered to av oid drift and downwind odor problems.
6. To maximiz e the value of the nutrients for crops production and to r educe 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 . Injectin g the wa ste or disking will
conserve nutrients and reduce odor problems .
Thi s plan is ba sed on the was te application method shown above. If you choose to change methods
in the future, you need to revi se this plan. Nutrient levels for different applications 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. Acreage requirements should be based on the w aste analysis report from
your wa ste management facility. In so me 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 the 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
2H .0217 adopted by the Environmental Management Commission.

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 bermudagrass), 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 to reach materity,
especially late in the sea son ( i.e . April or May) Shading may result if small grain gets too high and this will
definitely interfere with the 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 mowed to a height of about two inches before drilling for best
results.
Caution must be exercised in grazing or haying summer annuals under stressed conditions. Nitrate poisoning
may occur in livestock. Sampling forage or hay for nitrate levels is recommended.
Acres shown in the tables are con sidered to be the usable acres excluding required buffers, filters 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 field listed may, and most likely will be, more than the acres
shown in the tables.
See attached map showing the fields to be used for the utilization of animal waste.
SLUDGE APPLICATION :
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 mea sures to prevent over application of nutrients
or other elements. Your production facility will produce approximately 438 lbs. of plant available
nitrogen per year in the sludge.
If you remove sludge every S year s you will have approximately 2189 lbs . of PAN to utilize. Assuming
you apply this PAN to hybrid bermudagras s hayland at the rate of 300 lbs/acre you will need 7
acres of land. If you apply the sludge to corn at the rate of 125 lbs. of nitrogen per acre you will need 18
acres of land. Please be aware that these are only estmates of the PAN and the land needed . Actual
requirements could vary by 25% depending on the sludge waste analysis, soil types, reali stic yields, and
application methods.
APPLICATION OF WASTE BY IRRIGATION
Th e 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. Th e application amount should not exceed the available water holding capacity
L & W Farms, _Inc . Page4
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 irrrigate the acres shown in tables .
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 limitations. 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 instances should the volume of the waste be 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 the waste applicator to ensure that the spreader equipment is operated
properly to apply the correct rates shown in the tables. Failure to apply the recommended rates and amounts of
nitroge~ shown in the tables may make this plan invalid.
Call your technical spe<;:ialist after you have receive the waste analysis report for assistance in determining the
amount of waste per acre and the proper application rate prior to appling the waste.

WASTE 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.
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 waste. If the producer
does not own adequate land to properly dispose of waste, he/she shall provide a copy 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 facility to
secure an update ofthe Waste Utilization Plan when there is a change in the operation,
increase in the number of animals, method of utilization, or available land.
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, climatic conditions, and level
of management, unless there are regulations that restrict the rate of application for other
nutrients.
Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land that is eroding at S or more tons, but less than 10 tons per acre per
year providing grass filter strips are installed where runoff leaves the field. (See FOTG
standard 393-Filter Strip).
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 .
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" for guidance .)
Liquid waste shall be applied at rates not to exceed the soil infiltration rate that runoff
does not occur offsite or to the 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 or flies .
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. The potential for salt damage
from animal waste should also be considered.
10. Waste nutrients shall not be applied in fall or winter for spring planted crops on soils with a
high potentual 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 residenrial property boundary
and from any perennial stream or river (other than 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}.

13. Animal waste shall not be applied closer than 200 feet of dwellings other than those owned
by he 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 wetlands
provided they 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, wa ste shall be applied at agronomic rates in a
manner tt)at 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 vegtation 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 str uctures should be inspected regularly for evidences 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 illigal 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 vegetation 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-pl ant with no further applications of animal waste
during the crop season.
21. Highly visible markers shall be installed to mark the top and the bottom elevations of the

Dear Larry & Walter Ammons & Lois Bass:
OENR _FA 'ltfTEVlill REGIONAL OFFICE
Subject: Certificate of Coverage No. AWS820678
L & W Farms, Inc
Swine Waste Collection, Treatment,
Storage and Application System
Sampson County
On June 11 , 2004, the North Carolina Division of Water Quality (Division) issued a revised· State General
Permit for swine facilities. The General Permit was issued in accordance with the directive of Senate Bill
733 (Session Law 2003-28). ·
In accordance with your application received on January 22, 2003 and in accordance with the directive of
Senate Bill 733, we are hereby forwarding to you this Certificate of Coverage (COC) issued to Larry &
Walter Ammons & Lois Bass, authorizing the operation of the subject animal waste .collection, treatment,
storage and land application system in accordance with General Permit A WG 100000. The issuance of
this COC supercedes and terminates your previous COC Number A WS820678 which expires October 1,
2004.
Th.is approval shall consist of the operation of this system including, but not limited to, the management
of animal waste from the L & W Farms, Inc, located in Sampson County, with an animal capacity of no
greater than an annual average of 6080 Wean to Feeder swine and the application to land as specified in
the facility's Certified Animal Waste Management Plan (CA WMP). If this is a Farrow to Wean or
Farrow to Feeder operation, there may also be one boar for each 15 sows. Where boars are unneccessary,
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
The COC shall be effective from the date of issuance until September 30, 2009. Pursuant to this co·c,
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 CA WMP, 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.
Please carefully read this COC and the enclosed State General Permit. Since this is a revise d State
General Permit, it contains new requirements in addition to most of the conditions contained in the
previous State General Permit. Enclosed for your convenience is a package containing the new and
revi sed forms used for record keeping and reporting. Please pay careful attention to the record keeping
and mon itoring conditions in this permit.

If your Waste Utilization Plan has been developed based on site specific information, careful evaluation
of future samples is" necessary. -should· your records show that the current Waste Utilization Plan is
inaccurate you will need to have a new Waste Utilization Plan developed.
The issuance of this COC does not excuse the Permittee from the obligation to comply with _all applicable
laws, rules, standards, and ordinances (local, state, and federal), nor does issuance of a COC to operate
under this permit convey any property rights in either real or personal property.
Upon abandonment or depopulation for a period of four years or more, the Permittee must submit
documentation to the Division demonstrating that all current NRCS standards are met prior to restocking
ofthe facility.
Per l5A NCAC 2H .0225(c) a compliance boundary is provided for the facility and no new water supply
wells shall be constructed within the compliance boundary. Per NRCS standards a 100 foot separation
shall be maintained between water supply wells and any lagoon, storage pond, or any wetted area of a
spray field.
Please be advised that any violation of the terms and conditions specified in this COC, the General Permit
or the CA WMP may result in the revocation of this COC, or penalties in accordance with NCGS 143-
215.6A through 143-215.6C including civil penalties, criminal penalties, and injunctive relief.
If you wish to continue the activity permitted under the General Permit after the expiration date of the
General Permit, an application for renewal must be filed at least 180 days prior to expiration.
This COC is not automatically transferable. A name/ownership change application must be submitted to
the Division prior to a name change or change in ownership.
If any parts, requirements, or limitations contained in this COC are unacceptable, you have the right to
apply for an individual permit by contacting the staff member listed below for information on this
process. Unless such a request is made within 30 days, this COC shall be final and binding.

This plan will be implemented in the event that wastes from your
operation are leaking, overflowing, or running off the 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 problems are
listed below:
A. Lagoon overflow-possible solutions are:
a. Add soil to berm to increase elevation of dam, any
permanent alteration of the dam should be approved by a
qualified technical specialist.
b. Pump wastes to field at an acceptable rate.
c. Stop all additional flow to the lagoon-hold waste in the
house if possible.
d. Call a pumping contractor.
e. Make sure no surface water is entering lagoon.
B. Runoff from waste application field-action include:
a. Immediately stop waste application.
b. Create a temporary diversion or berm to contain the
waste.
c. Incorporate waste to reduce further runoff.
d. Evaluate and eliminate the reason<s> that caused 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 (flushing system) pump.
b. Stop irrigation pump.
c. Close valves to eliminate further discharge.
e. Repair all leaks prior to restarting pumps.
D. Leakage from flush system, houses, solids separators-actions
include:
a. Stop recycle (flushing system) pump.
b. Stop irrigation pump.
c. Make sure no siphon effect has been created.
d. Stop all flows in the house, flush systems, or solid
separators. ·
e. Repair all leaks prior to restarting pumps.

E. Leakage from base or sidewall o£ lagoon. Often this is seepage
as opposed to £lowing leaks-possible action:
a. Dig a small sump or ditch to catch all seepage, put in a
submersible pump, and pump back into lagoon.
b. If holes are caused by burrowing animals, trap or remove
animals and fill holes and compact with a clay type soil.
c. Have a professional evaluate the condition o£ 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 any surface waters?
b. Appro~imately how much was released and £or what
duration?
c. Any damage noted, such as employee injury, £ish kills, or
property damage?
d. Did the spill leave the property?
e. Does the spill have the potential to reach surface
waters?
£. Could a future rain event cause the spill to reach
surface waters?
g. Are potable water wells in danger (either on or o££ of
the property>? ·
h. How much reached surface waters?
3. Contact appropriate agencies.
a. During normal business hours, ~all your nwo <Division o£
Water Quality> regional o££ice, at 910-486-1541, after
hours, emergency number:919-733-3942. Your phone call
should include: YOUR NAME, FACILITY, TELEPHONE NUMBER,

OPERATION AND MAINTENANCE PLAN
This lagoon is designed £or waste treatment <permanent storage> and
180 days o£ temporary storage. The time required £or the planned
£luid level <permanent and temporary storage> to be reached may vary
due to site conditions, weather, flushing operations, and the amount
of fresh water added to the system.
The designed temporary storage consists of 180 days storage £or:
<1> waste £rom animals and <2> excess rainfall after evaporation. Also
included is storage for the 25 yr -24 hr storm £or the location and a
heavy rain £actor. The volume o£ waste generated from a given number
of animals will be fairly constant throughout the year and £rom year to
year, but excess rainfall will vary from year to year. The heavy rain
factor and 25 yr rainfall will not be a factor to consider in an annual
pumping cycle, but this storage volume must always be available.
The waste produced by the animals shall be utilized in accordance with
an approved waste utilization plan. Highly visible markers shall be
installed to mark the upper and lower elevations of the temporary
storage <pumping volume). Pumping ehall be done as necessary to
maintain the liquid level between these markers.
Pumping can be started or stopped at any time between these two
elevations for operating convenience as site conditions permit, such as
weather, soils, crop, and equipment in order to apply waste without
runof£ or leaching.
Land application of
method o£ disposal.
center pivot, guns,
taken when applying
waste water is recognized as an acceptable
Methods o£ application include solid set,
and traveling gun irrigation. Care should
waste to prevent damage to crops.
The following items are to be carried out:
be
1. Before wastes are introduced, the waste treatment lagoon shall be
charged to 1/2 ita treatment volume to prevent excessive odors during
start-up. Pre-charging reduces the concentration o£ the initial
waste entering the lagoon thereby reducing odors. Solids should be
covered with effluent at all times. When precharging is complete,
flush buildings with recycled lagoon liquid. Fresh wate·r···should not
be used £or flushing after initial filling.
2. The attached waste utilization plan shall be followed. This
plan recommends aaapling and testing o£ waste <see attachment>
before land application.
3. Begin temporary storage pump-out of the lagoon when fluid level
reaches the elevation 49.65 as marked by permanent marker. Stop pump-
out when the £luid level reaches elevation 46.80 • This temporary
storage less 25 yr and heavy rain contains 72762 cubic feet or
544257 gallons. \

4. The recommended maximum amount to apply per irrigation and
recommended maximum application rate is shown in the waste utilization
plan. Refer to the waste utilization plan for furth~r details.
5. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
6. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. Repair areas o£ the embankment that settle below the design settled
height or areas where cracki n g, sloughing, or "jug" holes develop.
8 . Repair waste inlet pipes that develop cracks or separate at the
joints.
9. Remove undesirable vegetative growth and £1oating or lodged debris.
10. All surface runo££ is to be diverted £rom the lagoon to stable
outlets when not inciuded as part o£ the design temporary storage.
11. A£ter five years the waste treatment lagoon shall be checked £or
sludge accumulation annually. I£ sludge has encroached into the
treatment volume, the sludge will be removed and applied at agronomic
rates baaed on analysis o£ the sludge. Treatment volume must have
a minimum o£ 4 £eet o£ depth £ree o£ sludge at all times.
12 . In December 1992, the Environmental Management Commission <EMC>
in North Carolina revised water quality regulations that address
animal operations. These rules became ef£ective on February 1,
1993 C15A NCAC 2H .0200>. This animal operation shall be operated
within the requirements o£ these rules and regulations.
13. Pipes that are used £or recycling e££luent to use as £lush water
and irrigation intakes must be placed 18 inches below the surface and
as £ar £rom the inlet discharge pipes as possible in order to provide
a cleaner effluent for flushing and to reduce odors when irrigating on
land. When these pipes are placed through the embankment, they should
be installed no more than two £eet below top o£ embankment and not in
the highest section of fill. The pipe trench shall be compacted with
clayey material or other material as approved by an engineer.

SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS
FOUNDATION PREPARATION:
The foundation area of the lagoon embankment and building pad shell be
cleared of trees. logs, stumps, roots, brush. boulders.sod and rubbish.
Satisfactory disposition will be made of all debris. The topapil from
the lagoon and pad area should be stripped and stockpiled for use on
the dike and pad areas. After stripping, the foundation area of the
lagoon embankment and building pad shall be thoroughly loosened prior
to placing the first lift of fill materiel to get a good bond.
EXCAVATION AND EARTHFILL PLACEMENT:
The completed excavation end earthfill shall conform to the lines,
grades. and elevations shown on the plana. Earthfill material shall
be free of material such as sod. roots. frozen soil, stones over
6 inches in ·diameter, and other objectionable material. To the extent
they are suitable, excavated materials can be used as fill. The fill
shall be brought up in approximately horizontal layers not to exceed 9
inches in thickness when loose and prior to compaction. Each layer
will be compacted by complete coverage with the hauling and spreading
equipment or standard taaping roller or other equiva~ent method.
Compaction equipment shell travel in a direction parallel to the main
axis of the fill. Clayey soils shall be co~apacted with a ""sheepsfoot"
or tamping roller. Coapactiop of the fill material shall be in accord-
ance with the specified requirements for compaction and moisture.
For the embankment, use the more impervious materials from the required
excavations. Construction of fill heights shall include 5 percent for
settlement. Dikes over 15 feet in height and with ·an impoundment
capacity of 10 acre-feet or more fall under the jurisdiction of the NC
Dam Safety Law. The height is defined as the difference in elevation
from the constructed height to the downstream toe of the dike.
Precautions shell be taken during construction to prevent excessive
erosion and sedimentation.
LINER: THE MINIMUM REQUIRED THICKNESS SHALL BE 1.6 ft.
NOTE: LINERS <PARTIAL OR FULL> ARE REQUIRED WHEN THE ATTACHED SOILS
INVESTIGATION REPORT SO INDICATES OR WHEN UNSUITABLE MATERIAL IS
ENCOUNTERED DURING CONSTRUCTION •. A TYPICAL CROSS SECTION OF THE LINER
IS INCLUDED IN THE DESIGN WHEN LINERS ARE REQUIRED BY THE SOILS REPORT.
When .areas of unsuitable material are encountered, they will be over-
excavated below finish grade to the specified depth as measured
perpendicular to the finish grade. The foundation shall be backfilled
as specified to grade with a NRCS approved material (ie-CL,SC,CH>.
REFER TO THE SOILS INVESTIGATION INFORMATION IN THE PLANS FOR SPECIAL
CONSIDERATIONS.

SHEET 2 OF 3
Soil liner material shall come £rom an approved borrow area. The
minimum water content o£ the liner material shall be optimum moisture
content which relates to that moisture content when the soil is kneaded
in the hand it will form a ball which does not readily separate. Water
shall be added to borrow as necessary to ~nsure proper moisture content
during placement o£ the liner. The moisture content o£ the liner
material shall not be less than optimum water content during placement.
The maximum water content relates to the soil material being too wet
£or efficient use of hauling equipment and proper compaction. Proper
compaction o£ the liner includes placement in 9 inch lifts and
compacted to at least 90 percent o£ the ·maximum ASTM D698 Dry Unit
Weight o£ the liner material unless otherwise specified. When smooth
or hard, the previous lift shall be scari£ied and moistened as needed
before placement o£ the next li£t.
The single most important £actor a£fecting the overall compacted perme-
ability o£ a clay liner, other than the type of clay used £or the
liner, is the efficient construction processing o£ the compacted liner.
The sequence o£ equipment use and the routing 6£ equipment in an estab-
lished pattern helps assure uniformity in the whole placement and
compaction process. For most clay soils, a tamping or sheeps£oot
roller is the preferable type o£ compaction equipment.
The soil liner shall be protected from the discharge o£ waste outlet
pipes. This can be done by using some type of energy dissipator<rocks>
or using flexible outlets on waste pipes.
Alternatives to soil liners are synthetic liners and bentonite sealant.
When these are specified, additional construction specifications are
included with this Constructibn Specification.
CUTOFF TRENCH:
A cuto££ trench shall be constructed under the embankment area when
shown on a typical cross section in the plans. The final depth o£ the
cutoff trench shall be determined by observation o£ the foundation
materials.
VEGETATION:
All exposed embankaent and other bare constructed areas shall be seeded
to the planned type of vegetation as soon as possible after construc-
tion according to the seeding specifications. Topsoil should be placed
on areas o£ the dike and pad to be seeded. Temporary seeding or mulch
ahall be use~ if the recoaaended permanent vegetation is out of season
dates for seeding. Permanent vegetation should be established as soon
as possible during the next period o£ approved seeding dates.
REMOVAL OF EXISTING TILE DRAINS
When specified, the contractor shall construct an observation trench
along the entire length o£ the embankment to a minimum o£ five feet
in depth. The trench shall have a bottom width adequate to accomodate
the equipment used £or excavation, backfill, and compaction operations

end the side slopes shall be 1:1 or £latter. When tile drains ere
encountered, the tile shall be removed to a minimum o£ 15 £eet beyond
the downstream embankment toe as measured perpendicular to the
embankment. I£ a tile line exists above the embankment it shall be
rerouted around the lagoon in an approved location. Backfilling
and compaction in the trench shall be in accordance with the EXCAVATION
AND EARTHFILL PLACEMENT requirements.
BOTTOM AND EDGES
The bottom o£ all lagoons shall be approximately level. The side
slopes shall be uniform £rom top to bottom. Scari£y the bottom and
side slopes of the lagoon a minimum depth o£ six inches and compact
with a "sheepsfoot .. Gr tamping roller to decrease the permeability
o£ the £iniahed bottom and side slopes.
CUALITY ASSURANCE
During construction of the earth embankment, a qualified inspector
as designated by the designer must be on site during construction
as necessary to verify proper construction. Testing wiil be required
as deemed necessary by the inspector and/or designer.
During construction o£ a clay,liner, a qualified construction
inspector as designated by the designer must be on site during con-
struction as necessary to verify the liner is installed in accordance
with NRCS South National Technical Center <SNTC> Technical Note
716 <Revised September 1993>. In the absence of supervision o£
construction by a qualified inspector, the liner must be tested to
ve~ify a maximum hydraulic conductivity of 0;00000~.25 em/sec.
When testing is required, the owner will be responsible £or furnish-
ing test results and certification that the construction meets
the design requirements. Any testa and certification should be
performed by a certified laboratory.

WASTE UTILIZATION PLAN
.-
Producer-----:LARRY & WALTER AMMONS
Name of Farm-:L & W FARMS, INC

County:SAMPSON
ROSEBORO NC 28382
Phone--------:910-5~4-6&35
Type Operation-------------:WEAN-FEED
Number of Animal-----------: &080
Storage Structure----------:A~aerobic Lagoon
Method of application ------:Irrigation
Amount of waste produced per year ---------------:
Amount of plant available N <PAN> produced/yea r-:
2567 tons/year
2 918 lbs. /year
The waste from your animal facility must be land appl i ed at a
specified r ate to pr eve nt pollution of surface wate r and/or
groundwater. The plant nutrients in the animal waste should be use
to reduce the amount of commercial fert i lizer 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 te~ts are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be
grown.
Several fa~tors are important in implementing your waste
utilization plan in order to maximize the fertili z er value of the
~aste and to ensure that it is applied in an en~ironmentally safe
manner:
1 . Always a pply 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 ~an utilize.
2. Soil types are i mportant as they have diffe r ent infiltration
rates, leaching potentials, cation exchange capacities, and
available water holding capacities.
3. Normally waste shall not be applied to land eroding at more
than 5 tons per acre per year. Waste may be applied to land
eroding at 5 or more tons per acre annually, but l e ss than
10 tons per acr e per year providing that adequate filter
strips are established.
4. Do not apply wast e on saturated soils, when it is t'aining, or
when the surface is frozen. Eithe r of these conditions may
in runoff to the surface waters which is not allowed under DWQ
regulations.
5. Wind conditions should also be considered to avoild dr i ft and
downwind odor p r oblems.
&. 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 ~r applied not mo r e than 30 days
prior to planting a crop or forages breaking dormancy.
Injecting the waste or disking will conserve nutrients and
, reduce odor problems.
This plan is based on the waste application method shown above. If
you choose to change method ~ in the future, you need t o revise
this plan . Nutrient levels for different application methods are
not the same.
The estimated acres needed to apply the anim a l waste is based on
typical nutrient content for this type of facility. Acreage
requirem en ts should be ba s ed on the waste analy s is re p o r t from
yo ur was t e manag e ment fa cility . In s ome c as e s y o u ma y wan t 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 the crop type. Lime must be applied to maintain pH in the
optimum range ~or speci~ic crop production.
This waste utilization plan, i~ carried out, meets the
requireMents for compliance with 15A NCAC 2H .0217 adopted by the
Environmental Management Commission.

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 gt~ain, etc, interseeded in
bermudagrass>, 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 to let small grain to reach maturity, especially late in
the season (i.e. Rpril or May). Shading may result if small grain
gets too high and this will definitely interfere with stand of
bermudagrass. This los s of stand will result in reduced yields and
less nitrogen being utilized. Rather than cutting small grai n 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 harv esting hay or silage two to three times during the
season, depending on time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late Sep~ember
or early October. Drilling is recommended over broadcasting .
Bermudagrass should be grazed or mowed to a height of about two
inches before drilling for best results.
Caution must be ex~rcised in grazing or haying summer annuals
under stressed conditions. Nitrate poisoning may occur in
livestock. Sampling forage or hay for nitrate levels is
recommended.
Acres shown in the 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 field listed may, and most likely will be, more than
the acres shown in the tables.
See attached map showing the fields to be used for the utilization
of animal waste.
SLUDGE APPLICATION:
The waste utilization plan must contain provision for periodic
l~nd application o f s ludge at agronomic rate s . The sludge will be
nutrient rich and will r equire precautionary measures to prevent
over application of nutrients or other elements. Your product ion
facility will produce approximately 438 lbs. of plant available
nitrogen per year in the sludge.
If you remove sludge every 5 years, you will have approximately
2189 lb s . of PAN to utilize. assuming you apply this PAN to
hybrid bermudagrass hayland at the rate of 300 lbs . of nitrogen
per acre, you will need · 7 acres of land. If you apply the
sludge to corn at the rate of 125 lbs. of nitrogen per acre, you
will need 18 acres of land. Please be aware that these are
only estimates of the PAN and land needed. Rctual requirements
could vary by 25~ depending on your sludge waste analysis, soil
types, realistic yi elds , and application methods.

APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not ~xceed the intake rate
of the soil at the time of irrigation such that runoff or pending
occurs. This rate is limited by initial soil moi s ture content,
soil structure, soil texture, water droplet size, and organic
solids. The application amount should not exceed the a v ailable
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 i s the method of land applicati o n fo r this
plan, it is th e r-esp o n s ibility of the pt·oduce t' a nd it·r·i gation·
designe r to en s ure that an irrigation system i s instal l ed to
p r operly irrigate the ac r e s shown in tables. Failure to apply the
r e commended r ates and a mounts of nitrogen shown in the tabl e may
make this plan invalid.
The following table i s p r ovided as a guide for establishing
application rates and amounts.

This is the maximum application amount allowed for the s oil
assuming the amount of nitrogen allowed for the c r op i s 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 s oil

Your facility is designed for 180 days of temporary storage and
the temporary storage must be removed on the average of once every
& months. In no instances should the volume of the waste be 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 rate prior to applying the
wast e.

System Calibration
Information presented in manufadurer'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 contin_ued 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 examp:e, operating the system with exc essive pressure
results in smaller droplets, greater potential for drift, and accelerates wear of the
sprinkler nozzle. Clogging of nozzles can result in pressure incr~ase. · Plugged
intakes or crystallization of mainlines will red uce operating pressure. Operating
below design pressure greatly reduces th e 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
cpllect flow ancf determine the application rate. Rain gauges work best because
they already have a graduated sca!.e from which to read the application amount
without having to ·perform additiooal calculations. However, pans, plastic buckets,
jars, or anything with a uniform Qpening a~d cross-section cari be used provi~ed
the liquid collect~ 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 c;:ontact your -irrigation
dealer or technical specialist for assistance.

SPECIFICATIONS FOR THE LAND APPLICATION OF WASTEWATER
IRRIGATION SYSTEM FOR MR. LARRY AND MR. WALTER AMMONS OF
L&W FARMS; L&W FARMS IS A WEAN-fEEDER OPERATION, IN
SAMPSON COUNTY
CONTRACTOR FOR: PRESTAGE FARMS, INC OF CLINTON, NC.
According to the data furnished by the owners Larry & Walter Ammons and Prestage Farms, INC.,
this is an operation that contains four wean to feeder buildings with 6400 capacity and one primary
and one secondary storage lagoons. The annual PAN (Plant Available Nitrogen) produced by this
particular operation will be 2918 pounds.
Soil type on this farm in the area where wastewater will be applied is Wagram, in both fields #1 & #2.
The Wagram series is a well drained Coastal Plain and terrace soils with thick sandy surface layers and
friable loamy subsoil's. The permeability rate is between 2.0" and 6.0" per hour in the top twenty inches
and between .6" and 2.0" per hour in the top 20 or 80 inches. The design precipitation rate, according
to the NRCS Technical Guide on Soils in North Carolina, is .6" per hour on WaB with Bermudagrass-
grazed as well as small grain-grazed cover. (NOTE: This recommendation is for typical irrigation, but
we have designed the following design with wastewater application in mind, that is the explanation for
the difference in the reconunended precipitation rates and the designed precipitation rates.)
The Nutrient Management Plan, developed by Prestage Farms, INC., include a cropping system of
Bermudagrass-grazed and Small grain-grazed. The total effective irrigated area as calculated by the
Irrigation Plan designer is approximately 12.12 acres. The area at the ends and on the sides of the pulls
will not receive uniform coverage during application. The effective area of irrigation is considered
approximately 70 percent of the throw diameter of the chosen sprinkler.
. The calculations made by Prestage Farms, INC. show that 12 acres of pasture land will utilize 3420
pounds of PAN. Since only pan will be generated annually, the 12.12 acres of pasture that can be
effectively irrigated will be more than adequate.
There should be adequate storage to allow time for application of the wastewater on the Bermudagrass-
grazed from March through October and applications on the Small grain-grazed from September through
April. After the system is in place and application becomes necessary, the manager needs to follow the
waste management plan as it is written. The total amount of wastewater that needs to be removed from
the lagoon will be based on the yearly rainfall amounts. Years where there is an unusually high rainfall
amount, more water will need to be pumped and sprayed on the pasture land, to keep the lagoon levels
within requirement. It is a good idea for the operators of this system to be familiar with average rainfalls
for their particular regions. This can help in the scheduling of their land applications. These can be
obtained at local extension offices or at NC State University. There are a number of places but these are
two well known locations.

LAND APPLICATION SYSTEM:
With our recommendation and the wants of the customer we have decided to use the ABI Hard Hose
Traveler; model 75 AT 820. The machine is equipped with 820' of 2.5" poly hose, a Nelson 100
end gun with a .812" ring nozzle and will acconunodate all of the customers needs. This will take
approximately 164 hours of pumping to remove the 1,167,360 gallons of wastewater produced by the
animals. This can be broken down into 20.5; 8hr days. The arc angle setting of the sprinkler will be
270 •. The arc angle is set to achieve less than or equal to precipitation rates, the guns can be run at
larger angles, but it is not reconunended to exceed 210·. These settings do not exceed the NRCS's
recommended precipitation rate . The wetted diameter of the sprinkler is 260', the gpm is 118 gallons
per minute, the pressure at the sprinkler is 70psi, and the effective diameter of the sprinkler throw is
182'.

The travel lane spacing is 70 percent of the wetted diameter. Under different testing systems, 70 percent
has been proven to be the best figure to use for the most uniform coverage. The travel lane spacing for
this design is 260' x . 70 = 182'. The risers will be set 180 feet apart to accommodate for the joints of
PVC pipe. The system should not be operated when wind conditions are lOmph or more. The best time
to run is when winds are less than 5mph.
The maximum precipitation rate of the irrigation equipment is not to exceed application rates stated earlier
in this plan, and to achieve this rate the traveler should be run at"the following speed.

A total of six hydrants will be required on the fann. The longest travel distance is 680' effective length
and the shortest is 261' effective length. When the system is first started at the beginning of the travel
lane, the cart should be allowed to remain in a stationary spot for a period of approximately 25 minutes
to allow for complete coverage at the end of the travel Jane. This time may have to be adjusted in
accordance with the days conditions. When the soil already has a higher moisture content than normal,
then the time should be decreased. At all times the operator should be present with the machine during
these time periods to prevent any run off or ponding of wastewater. Table 5 gives the times for each
travel lane including 25 minutes prior to pulling.
A pump which has a capacity of 118 gpm and can maintain a pressure of 116.52 psi (269.16 feet of head)
will be needed. A diesel power unit with a centrifugal pump is our recommendation for this site. This
gives the customer all of the specifications he needs with the reliability, ease of use, and mobility. The
pump that we recommend is the Berkeley B2EQHH. Due to the higher pressure the system will be
operatoring at, the efficiency of pump drops from approximately 70% down to about 55%. This loss in
efficiency will increase the fuel consumption, but the lower cost of the complete unit out-weighs the
added fuel cost. The operating range for the diesel engine is between 2800 and 3200 rpm. The engine
that will be used in this application is a John Deere 40200, which has been used in similar applications
and has proven to operate within all of the operators expectations.
There is a ± 5 feet of elevation on the property, approximately 2% slope.
Approximately 1600' of bell and gasketed 4" class 200 IPS PVC pipe will be needed for the underground
system supply line. All supply lines will be 4". The hydrants will be constructed out of sch 80 fittings
and class 200 pipe, this is to withstand any high water hammer. The top of the hydrants will be equipped
with 4" ceramic butterfly valves, between two flanges and a 4" aluminum male circle lock adapter on top
of the hydrant. Each end riser will be equipped with 2" sweep and 2 "air relief valve to allow any air in
the line to escape without causing any damage to the line.

The pump shall be attached to the underground mainline with a 15' flex assembly, consisting of 15' of
4" lay flat flex hose and two 4" circle lock fittings. The end that hooks to the pump will have a male
end, so that it can attach to the 4" fe~le on the pumping unit. The end going into the ground will have
a female end to attach to the male side of a 4" aluminum 90 deg elbow which is locked onto the top of
the hydrant whiCh is made like the field end riser, including male circle lock top, butterfly valve, 2"
sweep, sch 80 pressure fittings, 2" air relief, 2" adjustable pressure relief, and a 0-200 isolated pressure
gauge. A similar gauge will be at the traveler so the operator will be able to read the pressure at the
pump as well as at the reel.
The pipe will be installed with a minimum of 36" of cover over the pipe. This will prevent the pipeline
from being struck by any agricultural equipment. When trenching the PVC pipe all manufacturers
recommendations should be observed. Concrete thrust blocks should be poured at all tees , ells , gate
valves, and end risers in the system. See table 4 for thrust block sizes and see attached specs for thrust
block designs.
At the pump there will be a Berkeley 3" x 4" discharge priming valve. This swing type valve will allow
the operator to shutdown the system without the water draining back through the pump. The back
pressure of the water in the line will operate the valve. There will be a diaphragm valve on the suction
side of the pump to fill the pump and suction line when the operator starts up the system. At startup the
underground line should not be filled any faster than 40 gpm. There is a 4" butterfly valve on the entry
at the ground which will allow the operator to remove the pump from the site after shutdown and the
valve will prevent the water in the line from draining out.

APPLICATION OF WASTEWATER
The run time to apply .5" of wastewater is given in Table S. The length of the travel lane will
determine the length of time required. Another application of wastewater should not be applied until
the last amount of wastewater has been used up through Evaptranspiration, (ET). If no rainfall
occurs, that will nonnally range from three to five days. This may vary depending on the climate.
The total amount of wastewater to be applied to the pastures should not exceed the nutrient (plant
available nitrogen-PAN) requirements of the crop based on soil type. Each application of wastewater
should be limited to a maximum rate per hour and no more than .5" per irrigation cycle. It is our
recommendation that this is the maximum amount per cycle for Bennudagrass-grazed, and small
grain-grazed. During times of excessive rainfall the amount that needs to be applied may be
dramatiCally increased, due to added water in the lagoon.
Accurate records should be maintained on the operating time for each traveler. The pressure at the
pump, at the traveler, and at the gun should also be recorded to maintain accurate application rates.
Forms for recording data can be found in the North Carolina Certification Training for Operators of
Animal Waste Systems Manual, that each applicant received when they took part in the certification
training.
Pumping should occur as much as possible during the daylight hours. Running at night should be
avoided, when possible. Again it is very important not to run the systems when winds are more than
10 mph. At the beginning of each operation the pressures need to be checked against the parameters
as laid out in this design. If by some chance they do not match up, shutdown the system and make
the proper adjustments . The specifications must be followed exactly to prevent potential runoff and
ponding. Pumping should never occur during rainy periods or when the ground is saturated. The
operator will be held responsible for choosing the proper times to irrigate. Refer to the attached spec
sheet on when to irrigate. The operator should be on site when the system is running.
It is also highly recommended to conduct annual calibrations of your equipment. With the data
recorded at each operation and information provided in this design the operator can take a few easy
steps to ensure that the system is operating as it was originally designed.
PIPE INSTALLATION:
All of the pipe will be bell and gasket Class 200, IPS, PVC plastic pipe and the fittings will be
gasketed as like the ones manufactured by Harco. The hydrants will be made out of sch 80 slip
fittings, with class 200 PVC Pipe. Again as stated earlier, the pipe will have a minimum of 36" of
cover to prevent the pipeline from any damage. Concrete Thrust blocks will be poured at ells, tees,
and end hydrants (See attached material for specifications and design.) The thrust blocks are poured
in place to prevent the line from separating at any of the joints. It is very important that the thrust
blocks be poured in undistrubed earth this will prevent the pressure on the line from moving the
thrust block itself. After the line has been laid it should be covered up and compacted to prevent any
runoff of cover dirt and soft spots above the line.

MAINTENANCE:
There should be no land application of wastewater during freezing temperatures . The pump, the
above ground portion of the discharge pipe and the suction line should be drained during freezing
temperatures, to avoid ruptures. The risers should be drained to approximately one foot below the
surface during freezing temperatures. Any liquid in the underground pipe should be protected from
freezing. Check all valves, pressure relieves, gauges, and hydrant tops at least two to three times a
year to make sure they are operating properly. Make sure none of these are leaking or have any
malfunctioning parts. The pump should be well maintained and greased properly, (refer to the
operators manual for basic pump maintenance.) The engine must be serviced regularly with oil,
coolant, and lubrication (refer to the engine operators manual for instructions). The traveler also
needs regular maintenance. Inspection of the traveler and all of it's moving parts needs to be made
before each startup. (Refer to the traveler operators manual for proper maintenance .) It is a good
idea to wash the traveler and pump down periodically to reduce corrosion. When the pump is
removed from the system, make sure the butterfly valve on the system is closed to prevent anything
from getting into the pipeline. At every startup check for leaks and make sure the line holds a
constant pressure. If a leak is found, shut the system down and do not operate again until it can be
repaired. When any of the equipment is not in use, try to store it out of the direct sunlight, especially
the traveling gun, because the sun can cause damage to the poly pipe over a long period of time.

VELOCITY IN PVC PIPE:
The manufacturers of PVC pipe recorrunend that the velocity of the water traveling through the pipe
remain less than. or equal to 5 ft/sec. In this design the velocity is 3.01 ft/sec. This is a safe velocity
to operate the system. .

Safe Filling Rates .For Mainline Pipe
It is very important when filling an empty or near empty mainline not to
exceed velocities of 0.5 to 1.0 feet per second. Filling a mainline ·
faster than 1.0 fps may not allow the air i n the pipe to be properly
evacuated . Therefore the following chart indicates the approximate
maximum f·:ll rate (GPM) for most PVC, AC and ductile iron pipe . lines.

Pump . Stations should be selected that will allow the f.ill rate to be
adjusted accordingly. The fill rate can be increased at a r~te of
one (1) gpm every two or three seconds. This amounts to an average
increase of 30 gpm every minute during a refill operation.
It is necessary to use a "refill procedure " anytime a mainline has
drained down by 10% of its volume capacity .

FIGURE 3: CoefflcJent of Flow
Pipe C-Value
Old Steel 100
Aluminum -with couplers 120
Cement Asbestos 140
Plastic \ 150
As you can see, this formula is quite complicated. Figure 4 is a chart showing pressure losses and
velocity for various pipe sizes at various gaJionages (NOTE; Chart is for class 160 PVC with a C VaJue
of 150).
·EXAMPLE:
Pipe = PVC (Class 160)
Size = 10"
GPM = 1000 GPM
Length of Mainline = 1300'
From the chart, we find the PSI loss per 100' = .21 x 13oo·· = 2.73 PSI over 1300' of run
100
Head = 2.73 x 2.31 = 6.28' of head over 1300' of run
Velocity (V) = 4.15 ft/second
. We can use the chart along with the conversion factors list on Figure 4 to determine friction loss
for steel, aluminum and asbestos cement. ·
EXAMPLE:·
Pipe= Steel
Size= 10"
GPM = 1000
Length = 1300'
Friction Joss in 1300' PVC = 2.73 PSI = 6.30' head
Factor for steel x2.12 x2.12
Friction loss for 1300' of steel = 5.78 PSI or 13.36' head
Velocity (V) = 4.15'/sec. (sameas PVC in previous example)
A RainBird slide rule makes this determination very rapidly without need for calculation.
After obtaining the friction Joss · per 100 foot of pipe and multiplying this by the feet of pipe divid-
ed by 100, the total pipeline friction loss is known and can be used in the total head determina-
tion. as well as compared economically for proper pipe size.
You may incur instances where either the chart in Figure 4 or the Rain Bird slide rule cannot
be used. It will then be necessary to calculate the friction Joss and velocity. To do this, use the
formula in Figure 5.

MAINLINE REQUIREMENTS1
The connecting link between the pump and the irrigation system is the mainline. Mainline material
is normaJiy steel, aluminum with couplers, cement asbestos or plastic. Sizes can range from 5" to 48"·
plus. The following information may be used as a guide. Please consult with manufacturer for specific
design and installation information.
Generally with center pivot, a water source at the pivot is most convenient. When water is unavail-
able at the pivot, a mainline pipe is often used to connect the pivot to the water supply. To avoid in-
terference with farm operations and drive unit crossing, the mainline is generally buried.
. ~e ~roper size of mainline is a decis~n of economics .. Whenever the yearfy cost of owning a larger
prpe srze 1s greater than the yearfy pumpmg cost for pumpmg through the next smaller pipe size; then
one should use the smaller size pipe. A good rule of thumb would be not to exceed a velocity of water
in the pipe of five (5) feet per second. Water velocity in feet per second in a pipe can be determined
by the following formula:
Mainline Water Velocity
V = (0 .408) (GPM)
Q2
Where V = velocity in feet per second, GPM = gallons per minute, and 0 = inside diameter of circular
conduit in inches'.
Pipe thickness or class should be selected to handle the highest pressures likely to be enco.untered.
Because of the variable pressure operation of the corner system, the mainline pipe should be designed
to operate at a ·pressure of 30-40 PSI greater th~n the seleCted pivot pressure. The selection of flat
pump curves will be helpful in reducing the pressure fluctuations with the corner system.
FRICTION LOSS IN PIPE
Water flowing ·in a pipeline is always accompanied by a loss of pressure due to friction. The
degree or amount of loss depends on the smoothness of the Inside of the pipe walls, the
diameter of the pipe, the velocity, the quantity of water flowing in the pipe.
I Friction factors of pipe are determined by experiments. Every type of material pipe is made
from (steel, PVC, etc.} has different friction · loss characteristics.
I The Hazen and Williams formula is the basis for many friction Joss calculations. Friction
loss (F) is in units of "feet per 100 foot of pipe." Dividing by 2.31, friction loss is converted to
"PSI per 100 foot of pipe."

CONSTRUcnoN OF THRUST BLOCKS
Thrust blocks are anchors placed · between pipe or fittings and the solid trench wall. They
can be constructed from available lumber if braced properly.
However, the recommended blocking is concrete which is calculated to have a compres-
sion strength of 2,000 pounds per square inch. The mixture is one part cement, two parts washed
sand and five parts gravel. , .
Thrust blocks should be constructed so the bearing surface is in direct line with the major
force created by the pipe or fitting. See diagram. The earth bearing surface should be undis-
turbed. Only the simplest of forms is required. Typical thrust block installations are shown in
Figure 8. ·

THRUSTBLOCKS3
. Thrust blocking prevents main line from moving when the pressure load is applfed. In ef-
·tect, the thrust block transfers the load from the pipe to a wider load bearing surface.-Thrust
blocks are required where ffttlngs are used to change the direction (I.e., at all ties, elbows, wyes,
caps, vaJves, hydrants and reducers) of the pipeline. The tf:lrust backing must be formed against
a solid trench wall and these fitting areas must be e).Ccavated by hand because mechanical
equipment will damage the bearing surface of the trench wall. ·
. The size and type of thrust block depends on pipe size, line pressure, type of fitting, degree
of bend and type of soil. In most cases, the size and type of thrust block will be determined by
the engineer. Thrust block size may be calculated by the procedures shown:
STEP 1. Multiply the pipe pressure by the appropriate value shown in the followi~g table to get pounds
thrust per psi working pressure.

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 .

Field Calibration Procedures for Animal Wastewater Application Equipment
HARD HOSE AND CABLE TOW TRAVELER IRRIGATION SYSfEMS
R.O. Evans I.C. Barker I.T. Smith R.E. Sheffield
Land application equipment used on animal production farms must be field callbrated or
evaluated in accordance witb eJtisting design charts and tables according to State Rules that
went into effect September 1, 1996. Technical Specialist certifying waste management plans
after September 1, .1996 must also certify that operata~ have been provided calibration and
adjustment guidance for all land application equipment. The rules apply to irrigation systems
as well as all other types of liquid, slurry, or solid application equipinent.
Information presented in manufacturers clwts are based on average operating conditions for
relatively new equipment. Discharge I3tes and application rates change over time as
equipment ages and components wear. As a result, equipment should be field calibrated on a
regular basis to ensure that application tates and unifonnity are consistent with values used
during the system design and given in manufacturers specifications. Field calibration involves
collection and measurement of the material being applied at several locations in the
application area. This publication amtains step by step guidelines for field cahbration of hard
hose and cable tow traveler irrigation systems.
General Guidelines
Operating an irrigation system differently than assumed in the design Will alter the
application rate, unifonnity of coverage, and subsequently the application uniformity.
Operating with excessive pressure results in smaller droplets, greater potential for drift, and
accelerates wear of the sprinkler nozzle. 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. Clogging of nozzles or
crystal1intion of mainlines can result in pressure increase and reduced flow. Plugged intakes
will reduce operating pressure. An operating pressure below design pressure greatly ~uces
the coverage diameter and application uniformity. Field calibration helps ensure that nutrients
from animal waste are applied unifonnly and at proper rates.
The calibration of a hard hose or cable tow system involves setting out collection containers,
operating the system, measuring the amount of wastewater collected in each container, then
computing the avexage application volume and application unifonnity.
An in-line flow meter installed in the main irrigation line provides a good "estimate" of the
total volume pumped from the lagoon during each irrigation cycle. The average application
depth can be determined by dividing the pumped · volume by the application area. The
average application depth is computed from the fonnula:
Volume Pumped (gallons)
Average application depth (inches) = ----------
27,154 (gallac-in) X Application area (acres)

The average application depth is the average amount applied throughout the field.
Unfortunately, sprinklers do not apply the same depth of water throughout their wetted
diameter. Under normal operating conditions, application depth decreases towards the outer
perimeter of the wetted diameter. Big gun sprinkler sy~mS typically have overlap based on
a design sprinkler spacing of 70 to 80 percent of the wetted sprinkler diameter to compensate
for the declining application along the outer perimeter. When operated at the design pressure,
this overlap results in acceptable application uniformity. But, when operated improper I y, well ·
designed systems will not provide acceptable application uniformity. For example, if the
pressure is too low, the application depth will be several times higher near the center of
sprinkler and water will not be thrown as far from the sprinkler as indicated in manufacturers
charts. Even through the average application depth may be acceptable, some areas receive
excessively high application while others receive no application at all. When applying
wastewater high in nutrients, it is important to determine the application unifonnity.
Collection containers distributed throughout the application area must be used to evaluate
application uniformity.
Many types of containers can be used to collect flow and determine the application
unifonnity. Standard rain gauges work best and are recommended because they already have
a graduated scale from which to read the application depth without having to perfonn
mathematical conversions.
· Pans, plastic buckets, jars, or anything with a uniform opening and cross section can be used
provided the container is deep enough to prevent splash (at least 4 inches deep), excessive
evapOration, and the liquid collected can be easily transferred to a scaled container for
measuring. All containers should be the ~e size and shape to simplify application depth
computations. ·
· All collection containers should be set up at the same height relative to the height of
sprinkler discharge elevation (nozzle). Normally, the_ top of each container should be no
mo~ than 36 inches above the ground. Collectors should be located so that there is no
interference from the crop. The crop caitopy should be trimmed to preclude interference or
splash into the collection container.
Calibration should be performed during periods of low evaporation. Best times are before 10
am or after 4 pm on days with light wind Qess than 5 MPH). On cool, cloudy days the
·calibration can be performed anytime during the day ~hen wind velocity is low.
The volume ·collected during calibration should be read soon after the sprinkler gun cart has
moved one wetted radius past the collection gauges to minimize evaporation from the rain
gauge. Where a procedure must be performed more than once, containers should be read and
values recorded immediately after each set up.
Calibration set-up for Hard Hose and Cable Tow Traveling Guns
· Hard hose and cable tow traveling guns are calibrated by placing a row (transect) of
collection containers or gauges perpendicular to the direction of travel , Figure 1. The outer

Interpret the calibration data and make necessary adjUstments.
For travelers with proper overlap and operated in light wind, an application wtiformity
coefficient greater than 80 is common.
Application unifonnity between 60 to 80 is in the "good" range and is acceptable for
wastewater application.
Generally, an application uniformity below 60 is considered unacceptable for wastewater
irrigation using travelers. If the computed Uc is less than 60, system adjustments are
required. Contact your irrigation dealer or Certified Technical Specialist for assistance.

~mount of waste produced per year---------------;
~mount of pl~nt available N <PAN> produced/year-:
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 anirnal waste should be use
to reduce the amo~nt bf commercial fertilizer required for the
~raps in the fields where the waste is to be applied.
This waste utilization plan uses nitrogen as.the limiting
nutrient. Waste ~hould be analyzed b~fore each application cycle.
~nnual soil tests are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be
;~rown.
Several factors are important in implementing your waste
utilization plan in order to mawimize the fertilizer value of the
~aste and to ensure that it is applied in an environmentally _safe
manner:
1. Always apply wa6te 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. So i 1 types are. import ant as they have different i nf il trat ion
rates, leaching potentials, cation exchange capacities, and
available water holding capacities.
3. Normally waste shall not be applied to land eroding at more
than 5 tons per acre per ~ear. Waste may be applied to land
eroding at 5 or more tons per acre annually~ but les~ than
1~ tons per acre per year providing that adequate filter
strips are established.
4. Do not apply waste on satm·~ated soils, when it is raining, or
when the surface is frozen. Either of these conditions may
in runoff to the surface waters which is not Bllowed under DWQ
r·e gu lations.
5. Wind conditions should also be considered to avoild drift and
downwind odor problems.
&. To maximize the value of the nutri~nts for crop production and
to reduce the putential 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 con~erve nutrients and
reduce odor problems.
This plan is based on the waste app 1 icat ion method shown above. If
you choose to change methods in the future, you need to revise
this plan. Nutrient levels for diff~rent application methods are
not the same.
The estimated Beres needed to apply the animal waste is based on
typical nutrie~t content for this type of facility. Acreage
requir~ments $hould be based on the waste analy~is report from
yout~ waste management facility. In some cases you may w.;wt to have

Acr~a shown in 'the tables are considered to be the usable acres
eMcluding required buffers , filter strips along ditches, odd
areas unable to be i~rigated, and perimeter areas not receiving

acres in the field listed may, and most likely will be, ~ore than
the acres shown in the tables.
See at~ached map showing the ·fields to be used for the utilization
of animal waste.
SLUDGE RPPLICATION:
The waste utilization plan must contain provision for ~eriodic
l~nd application of sludge at agronomic rates. Th~ sludge will be
nttrient rich and will require precautionary measures to prevent
O\er application of nutrlen~s or other elements. Your production
fi.cility will produce app~oKimately 438 lbs. of plant available
nitrogen per year in the sludge. ·
If you re111ove sludge every 5 years, you will have approKimately
2l8~ lbs. of PAN to utilize. assum i ng you apply this PAN to
h ~·b i"' id bet~m udagras s hay land at the rate of 300 1 bs . of nitrogen
~··r· acre, you will need 7 acres of land. lf you apply the
~:.udge to corn at the rate ~f 125 lbs. of nitrogen per acr~, you
w :.ll need 18 acres of land. P 1 ease be aware that these are
o11ly estimates of th£> PAN and land needed. Actual requirements
cuuld vary by 251-depending on your sll..1dge waste analyiis, soi 1
t~tpes, t•ealistic yields, and appli ca tion met h ods.·
