The waste from your animal facility must be land applied at a specified
rate to prevent pollution of surface and/or groundwater. The plant
nutrients in the animal waste should be used to reduce the amount of
commercial fertilizer required for the crops in the fields where waste
is to be applied. This waste utilization plan uses nitrogen as the
limiting nutrient. Waste should be analyzed before each application
cycle. Annual soil tests are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization
plan in order to maximize the fertilizer value of the waste and to
ensure that it is applied in an environmentally safe manner. Always
apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can
utilize. Soil types are important as they have different infiltration
rates, leaching potentials, cation exchange capacities, and available
water holding capacities. Normally waste shall not be applied to land
eroding at greater than 5 tons per acre per year. With special pre-
cautions, waste may be applied to land eroding at up to 10 tons per
acre per year. Do not apply waste on saturated soils, when it is
raining, or when the surface is frozen. Either of these conditions
may result in runoff to surface waters which is not allowed under DWQ
regulations. Wind conditions should also be considered to avoid drift
and downwind odor problems. To maximize the value of the nutrients
for crop production and to reduce the potential for pollution, the
waste should be applied to a growing crop or applied to bare ground
not more than 30 days prior to planting. Injecting the waste or
disking will conserve nutrients and reduce odor problems.
This plan is based on waste application through irrigation for this
is the manner in which you have chosen to apply your waste. If you
choose to -inject the waste in the future, you need to revise this
plan. Nutrient levels for injecting waste and irrigating waste are
not the same.
The estimated acres needed to apply the animal waste is based on
typical nutrient content for this type of facility. Acreage require-
ments should be based on the waste analysis report from your waste
management facility. Attached you will find information on proper
sampling techniques, preparation, and transfer of waste samples to
the lab for analysis.
u
This waste utilization plan, if carried out, meets the requirements RECENED 1 DENR I DWQ
for compliance with 15A NCAC 2H.0217 adopted by the Environmental Aggjfpr protection Section

Acres shown in each of the preceding tables are considered to be the
usable acres excluding required buffers, filter strips along ditches,
odd areas unable to be irrigated, and perimeter areas not receiving
full application rates due to equipment limitations. Actual total
acres in the fields listed may, and most likely will be, more than
the acres shown in the tables.
NOTE: The Waste Utilization flan 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 32:1 - 1,1L pounds of plant
available nitrogen (PAN) per year in the sludge that will need to be
removed on a periodic basis. This figure is PAN when broadcasting
the sludge equipment, may be needed when you remove this sludge.
See attached map showing the fields to be used for the utilization of
waste water.
APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not exceed the intake rate of
the soil at the time of irrigation such that runoff or ponding occurs.
This rate is limited by initial soil moisture content, soil structure,
soil texture, water droplet size, and organic solids. The application
amount should not exceed the available water holding capacity of the
soil at the time of irrigation nor should the plant available nitrogen
applied exceed the nitrogen needs of the crop.
Your facility is designed for 180 days of temporary storage
and the temporary storage must be removed on the average of once every
6 months. In no instance should the volume of waste being stored in
your structure be within 1. 7 feet of the top of the dike.

WASTE UTILIZATION PLAN Page 5
If surface irrigation is the method of land application for this plan, it
it is the responsibility of the producer and irrigation (signer to
ensure that an irrigation system is installed to properly irrigate the
acres shown in Tables 1 and 2. Failure to apply the recommended rates
and amounts of Nitrogen shown in the tables may make this plan invalid
Call your Agriment Services representative for assistance in determining
the amount of waste per acre and the proper application rate
prior to beginning the application of your waste.

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

WASTE UTILIZATION PLAN
Page 7
10. Waste nutrients shall not be applied in fall or winter for spring
planted crops on soils with a high potential for leaching. Waste
nutrient loading rates on these soils should be held to a minimum
_ and a suitable winter cover crop planted to take up released
nutrients. Waste shall not be applied more than 30 days prior to
planting of a crop on bare soil.
11. Animal waste shall not be applied closer than 25 feet to surface
water. This distance may be reduced for waters that are not perennial
provided adequate vegetative filter strips are present. (See standard
393 - Filter Strips)
12. Animal waste shall not be applied closer than 100 feet to wells.
13. Animal waste shall not be applied closer than 200 feet of dwellings
other than those owned by the 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, drainage ways,
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 should not be applied on grassed waterways that discharge
into water courses, except when applied at agronomic rates and the
application causes no runoff or drift from the site.
16. Domestic and industrial waste from wash down facilities, showers,
toilets, sinks, etc., shall not be discharged into the animal waste
management system.
17. Lagoons and other uncovered waste containment structures must maintain
a maximum operating level to provide adequate storage for a 25-year,
24-hour storm event in addition to one (1) foot mandatory freeboard.
18. A protective cover of appropriate vegetation will be established on
all disturbed areas (lagoon embankments, berms, pipe runs, etc.).
If needed, special vegetation shall be provided for these areas and
and shall be fenced, as necessary to protect the vegetation.
Vegetation such as trees, shrubs, and other woody species, etc. are
limited to areas where considered appropriate. Lagoon areas should be
kept mowed and accessible. Lagoon berms and structures should be
inspected regularly for evidence of erosion, leakage or discharge.
19. 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.
20. 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.

WASTE UTILIZATION PLAN
Page 8
21. 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.
22. 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.
23. Waste shall be tested within sixty days of utilization and soil shall
be tested at least annually at crop sites where waste products are
applied.- Nitrogen shall be the rate - determining element. Zinc
and copper levels in the soils shall be monitored and alternative crop
sites shall be used when these metals approach excessive levels. pH
and waste analysis records shall be kept for five years. Poultry dry
waste application records shall be maintained for three years. Waste
application records for all other waste shall be maintained for five
years.
24. Dead animals will be disposed of in a manner that meets North
Carolina State regulations or other States' regulations.

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 24, 2003 and in accordance with the directive of
Senate Bill 733, we are hereby forwarding to you this Certificate of Coverage (COC) issued to B & W
Hog Farms, Inc., authorizing the operation of the subject animal waste collection, treatment, storage and
land application system in accordance with General Permit AWG I00000. The issuance of this COC
supercedes and terminates your previous COC Number AWS820058 which expires October 1, 2004.
This approval shall consist of the operation of this system including, but not limited to, the management
of animal waste from the Barefoot Nursery, located in Sampson County, with an animal capacity of no
greater than an annual average of 5120 Wean to Feeder swine and the application to land as specified in
the facility's Certified Animal Waste Management Plan (CAWMP). 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 COC,
you are authorized and required to operate the system in conformity with the conditions and limitations as
specified in the General Permit, the facility's CAWMP, and this COC. An adequate system for collecting
and maintaining the required monitoring data and operational information must be established for this
facility. Any increase in waste production greater than the certified design capacity or increase in number
of animals authorized by this COC (as provided above) will require a modification to the CAWMP and
this COC and must be completed prior to actual increase in either wastewater flow or number of animals.
Please carefully read this COC and the enclosed State General Permit. Since this is a revised 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
revised forms used for record keeping and reporting. Please 12gy careful attention to the record kegpin
and monitoring 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
of the facility.
Per 15A 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 CAWMP 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.

Dear Mr. Heath,
SAY ETTEVILLE
RIEG- OFFICE
On 7/18/001 reported a problem with the waste management system at facility # 82-58.
The infraction occurred during the Operation Review Inspection conducted by Mrs.
Margaret O'Keefe of the Division of Soil & Water. The problem was a flush tank overflow
due to a faulty timer that halted the dump mechanism. At first notice, the recycle water to
the tank was ceased and a berm was established to contain the thin layer or liquid waste
on the ground. Mrs. O'Keefe and I observed this action and it was noted in her inspection
report. We did not notice any run-off. The faulty timer has been repaired and more
frequent inspections are planned in the future to catch potential tank problems sooner. If
you have any questions please give me or Margaret a call.

Swine Waste Collection, Treatment,
Storage and Application System
Sampson County
In accordance with your application received on March 22, 2000, we are forwarding this
Certificate of Coverage (COC) issued to Larry Barefoot, authorizing the operation of the subject animal
waste collection, treatment, storage and land application system in accordance with General Permit
AWG100000. This approval shall consist of the operation of this system including, but not Iimited to,
the management of animal waste from the Barefoot Nursery, located in Sampson County, with an animal
capacity of no greater than 5120 Wean to Feeder and the application to land as specified in the Certified
Animal Waste Management Plan (CAW_N4P).
The COC shall be effective from the date of issuance until April 30, 2003. Pursuant to this COC,
you are authorized and required to operate the system in conformity with the conditions and limitations
as specified in the General Permit, the facility's CAWMP, and this COC, with no discharge of wastes to
surface waters. An adequate system for collecting and maintaining the required monitoring data and
operational information must be established for this farm. Any increase in waste production greater than
the certified design capacity or increase in number of stocked animals above the number authorized by
this COC will require a modification to the CAWMP and this COC and shall be completed prior to
actual increase in either wastewater flow or number of animals.
Please be advised that any violation of the terms and conditions specified in this COC, the General
Permit or the CAWMP 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.

The waste from your animal facility must be land applied at a specified
rate to prevent pollution of surface and/or groundwater. The plant
nutrients in the animal waste should be used to reduce the amount of
commercial fertilizer required for the crops in the fields where waste
is to be applied. This waste utilization plan uses nitrogen as the
limiting nutrient. Waste should be analyzed before each application
cycle. Annual soil tests are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization
plan in order to maximize the fertilizer value of the waste and to
ensure that it is applied in an environmentally safe manner. Always
apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can
utilize. Soil types are important as they have different infiltration
rates, leaching potentials, cation exchange capacities, and available
water holding capacities. Normally waste shall not be applied to land
eroding at greater than 5 tons per acre per year. With special pre-
cautions, waste may be applied to land eroding at up to 10 tons per
acre per year. Do not apply waste on saturated soils, when it is
raining, or when the surface is frozen. Either of these conditions
may result in runoff to surface waters which is not allowed under DWQ
regulations. Wind conditions should also be considered to avoid drift
and downwind odor problems. To maximize the value of the nutrients
for crop production and to reduce the potential for pollution, the
waste should be applied to a growing crop or applied to bare ground
not more than 30 days prior to planting. Injecting the waste or
disking will conserve nutrients and reduce odor problems.
This plan is based on waste application through irrigation for this
is the manner in which you have chosen to apply your waste. If you
choose to inject the waste in the future, you need to revise this
plan. Nutrient levels for injecting waste and irrigating waste are
not the same.
The estimated acres needed to apply the animal waste is based on
typical nutrient content for this type of facility. Acreage require-
ments should be based on the waste analysis report from your waste
management facility. Attached you will find information on proper
sampling techniques, preparation, and transfer of waste samples to
the lab for analysis.
This waste utilization plan, if carried out, meets the requirements
for compliance with 15A NCAC 2H.0217 adopted by the Environmental
Management Commission.

and have appropriate equipment to apply the waste in a timely manner.
The following acreage will be needed for waste'application based on
the crop to be grown, soil type and surface application.

while meeting the N requirements. Beginning in 1996 the Coastal Zone
Management Act will require farmers in some eastern counties of NC to
have a nutrient management plan that addresses all nutrients. This
plan only addresses Nitrogen.

odd areas unable to be irrigated, and perimeter areas not receiving
full application rates due to equipment limitations. Actual total
acres in the fields listed may, and most likely will be, more than
the acres shown in the tables.
NOTE: The Waste Utilization Plan must contain provisions for periodic
land application of sludge at agronomic rates. The sludge will be
nutrient rich and will require precautionary measures to prevent
over application of nutrients or other elements. Your production
facility will produce approximately /,At%, pounds of plant
available nitrogen (PAN) per year in the sludge that will need to be
removed on a periodic basis. This figure is PAN when broadcasting
the sludge equipment, may be needed when you remove this sludge.
See attached map showing the fields to be used for the utilization of
waste water.
APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not exceed the intake rate of
the soil at the time of irrigation such that runoff or ponding occurs.
This rate is limited by initial soil moisture content, soil structure,
soil texture, water droplet size, and organic solids. The application
amount should not exceed the available water holding capacity of the
soil at the time of irrigation nor should the plant available nitrogen
applied exceed the nitrogen needs of the crop.
Your facility is designed for 180 days of temporary storage
and the temporary storage must be removed on the average of once every
6 months. In no instance should the volume of waste being stored in
your structure be within _L:. 7 feet of the top of the dike.

WASTE UTILIZATION PLAN Page 5
If surface irrigation is the method of land application for this plan, it
it is the responsibility of the producer and irrigation (signer to
ensure that an irrigation system is installed to properly irrigate the
acres shown in Tables 1 and 2. Failure to apply the recommended rates
and amounts of Nitrogen shown in the tables may make this plan invalid
Call your Agriment Services representative for assistance in determining
the amount of waste per acre and the proper application rate
prior to beginning the application of your waste.

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

WASTE UTILIZATION PLAN
Page 7
10. Waste nutrients shall not be applied in fall or winter for spring
planted crops on soils with a high potential for leaching. Waste
nutrient loading rates on these soils should be held to a minimum
and a suitable winter cover crop planted to take up released
nutrients. Waste shall not be applied more than 30 days prior to
planting of a crop on bare soil.
11. Animal waste shall not be applied closer than 25 feet to surface
water. This distance may be reduced for waters that are not perennial
provided adequate vegetative filter strips are present. (See standard
393 - Filter Strips)
12. Animal waste shall not be applied closer than 100 feet to wells.
13. Animal waste shall not be applied closer than 200 feet of dwellings
other than those owned by the 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, drainage ways,
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".
i Animal waste should not be applied on grassed waterways that discharge
into water courses, except when applied at agronomic rates and the
application causes no runoff or drift from the site.
16. Domestic and industrial waste from wash down facilities, showers,
toilets, sinks, etc., shall not be discharged into the animal waste
management system.
17. Lagoons and other uncovered waste containment structures must maintain
a maximum operating level to provide adequate storage for a 25-year,
24-hour storm event in addition to one (1) foot mandatory freeboard.
18. A protective cover of appropriate vegetation will be established on
all disturbed areas (lagoon embankments, berms, pipe runs, etc.).
If needed, special vegetation shall be provided for these areas and
and shall be fenced, as necessary to protect the v egetabon.
Vegetation such as trees, shrubs, and other woody species, etc. are
limited to areas where considered appropriate. Lagoon areas should be
kept mowed and accessible. Lagoon berms and structures should be
inspected regularly for evidence of erosion, leakage or discharge.
_ 19. 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.
20. 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.

WASTE UTILIZATION PLAN
Page 8
21. 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.
22. 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.
23. Waste shall be tested within sixty days of utilization and soil shall
be tested at least annually at crop sites where waste products are
applied. Nitrogen shall be the rate - determining element. Zinc
and copper levels in the soils shall be monitored and altemative crop
sites shall be used when these metals approach excessive levels. pH
and waste analysis records shall be kept for five years. Poultry dry
waste application records shall be maintained for three years. Waste
application records for all other waste shall be maintained for five
years.
24. Dead animals will be disposed of in a manner that meets North
Carolina State regulations or other States' 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.

needed) to be stripped of topsoil (3") and stockpiled for use on dike
and pad slopes (2--3"). The topsoiling quantity is in excess of
amounts specified on page one (1).
Cut -of f - Trench:
--------------
A cut-off trench (when specified) shall be installed as shown in
the plans.
Construction:
------------
Construction of excavated and earthfiII areas shall be performed
to the neat lines and grades as planned. Deviations from this will
require prior approval of the SCS. arthfiII shall be placed in
max. of 6" lifts and not placed in standing water. Compaction
shall be performed by the construction equipment or sheeps-foot roller
during placement. The embankment of the lagoon shall be installed
using the more impervious materials. Construction of fill
heights shall include ten (10) percent for settlement. To
protect against seepage, when areas of unsuitable material are
encountered, they will need to be excavated a minimum of one (1) foot
below grade and backfiIIed and compacted with a SCS approved
material (i.e.--CL,SC,CH). Refer to the soil investigation
information in the plans for special considerations. Precautions
should be taken -during construction to prevent excessive erosion
and sedimentation.
Vegetation:
All exposed embankment and other bare constructed areas shall be
seeded to the planned type of vegetation as soon as possible
after construction according to seeding specifications sheet.

OPERATION AND MAINTENANCE PLAN
J..-.- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
This lagoon is designed for waste treatment (permanent storage) with
minimum odor control. The time required for the planned fluid level
to be reached (permanent + temporary storage) may vary due to
flushing operations and the amount of fresh water to be added to the
system.
The designed 6 months temporary storage is an estimated volume" -
based on : 1) waste from animals; 2) excess rainfall after _
evaporation; and 8)-the----largest=24-hour--(one --day) rainfaI l -that -- -"- ----"-
occurs on the average of once every 25 years. The volume of
waste generated from a given number of animals will be fairly
constant throughout the year and from year to year. This
estimate is based on 7 inches of excess rainfall which is -
equal to or exceeds the highest 6 months excess in a year.
The-i3verage annual excess=-rai nfal 1 ­ i s approx imate I y 8 inches. - - -
Therefore, ---an- average of 8 inches of excess rainfal-i 'wi-I I - - - -- - ----� --
need to be pumped each year. The 25 year rainfall will not be a
factor to consider in an annual pumping cycle, but this storage
volume must always be available. A maximum elevation is
determined in each design to begin pumping and this is usually -
the outlet i nve rt of pipe(s) from bu i 1 d i ng (s) . -If the outlet -
--s-- --p r-pe--I s-not-i p-ump-i-ng";-a -- - - ---
permanent marker must be installed on this elevation to
indicate when pumping should begin. An elevation must be
established to stop pumping to maintain minimum treatment depth
(6 feet). Pumping can be started or stopped any time between
these two elevations for operating convenience as site
conditions permit (weather, soils, crop, and equipment to apply
waste without runoff or leaching).
Land application of waste water is recognized as an acceptable
method of disposal. Methods of application include solid set,
center pivot, guns, and traveling gun irrigation. Care should
be taken when applying waste to -prevent runoff from the field
or damage to crops.
The following items are to be carried out:
1. It is strongly recommended tha the treatment lagoon be pre— --"
charged to 1/2 its capacity to prevent excessive odors during
start-up. Pre -charging reduces the concentration of the initial
waste entering the lagoon thereby reducing odors. Solids
should be covered with effluent at all times. When pre-
charging is completed, flush buildings with recycled lagoon
liquid. Fresh water should not be used for flushing after
initial filling.
2. The attached waste utiiization plan shall be followed.
This plan recommends sampling and testing of waste (see
Attachment B) before land application.

3. Begin pump -out of the lagoon when fluid level reaches eleve-
tion 50.00 as marked by permanent markers.- Stop pump -out - - when the fluid level reaches elevation 48.00 or before
fluid depth is less than 6 feet deep (this prevents the loss of
favorable bacteria). The design temporary storage, less 25 year
storm is 58601 cub-i-c--feet--or---- - 438338 gallons. As stated - ---
before, this volume will vary considerably from year to year. _
4. The recommended maximum amount to apply per irrigation is one
(1) inch and the recommended maximum application rate is 0.4
inches per hour.
5. Keep vegetation on 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.
i 7. All surface runoff is to be diverted from the lagoon to
stable outlets.
8. Keep a minimum of 100 feet crop! and buffer or 25 feet of grass
vegetated buffer around waste utilization fields, particularly adjacent
to ponds, lakes, streams, open ditches, etc. Do not pump within
300 feet of a residence or within.1W feet of a well.
9. The Clean Water Act of 1977 prohibits the discharge of
pollutants into waters of the United States. The Department of
Environment, Health, and Natural Resources, Division of Environ-
mental Management, has the responsibility for enforcing this law.

This plan will be implemented in the event that wastes from your operation are leaking,
overflowing or running off site. You should not wait until wastes reach surface waters
or leave you 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 ore may not be
possible. Suggested responses to some possible problems are listed belwo.
A. Lagoon overflow -possible solutions are:
a. Add soil to berm to increase elevation of dam.
b. Pump wastes to fields at an acceptable rate.
c. Stop all flows to the lagoon immediately.
d. Call a pumping contractor.
e. Make sure no surface water is entering lagoon.
B. Runoff from waste application field -actions include:
a. Immediately stop waste application.
b. Create a temporary diversion to contain waste.
c. Incorporate waste to reduce runoff.
d. Evaluate and eliminate the reason(s) that cause the runoff.
e. Evaluate the application rates for the fields where runoff occurred.
C. Leakage from the waste pipes and sprinklers -action include:
a. Stop recycle pump.
b. Stop irrigation pump.
c. Close valves to eliminate further discharge.
d. Repair all leaks prior to restarting pumps.
D. Leakage from flush systems, houses, solid separators -action include:
a. Stop recycle pump.
b. Stop irrigation pump.
c. Make sure siphon occurs.
d. Stop all flows in the house, flush systems, or solid separators.
E. Leakage from base or sidewall of lagoon. Often this is seepage as opposed
to flowing leaks -possible action:

{ ) Any method which in the professional opinion of the State
Veterinarian would make possib�e the salvage of part of a dead
animal's value without endanger'Eng human or animal health. (Written
approval of the State Veterinariz,n must be attached)

OPERATION & MAINTENANCE PLAN
Proper lagoon liquid 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 the thunderstorm season in the summertime. This means
that at the first signs of plant growth in the later winter/early spring, irrigation according to
a farm waste management plan should be done whenever the land is 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
irrigate 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 fertilizer 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

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 of 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.
i
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 or 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 Igoon 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
I 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 inflow 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 occour at least two weeks prior to the
addition of wastewater.
6. Maintain a periodic check on the Iagoon 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 lever (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.
Do not pump the lagoon liquid level lower that 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:

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 phosphores, 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.
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.
A
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.

IRRIGATION SYSTEM NARRATIVE
LARRY BAREFOOT NURSERY
SAMPSON COUNTY
EQUIPMENT
This irrigation system is designed to use two(2) movable Nelson P 100 guns. Each gun
should use a .60 taper bore nozzle on all settings. The system will be supplied by a
Berkeley B 1.5 TBM pump powered by a 10 horsepower electric engine. All below
ground pipe should be 4" Class 160 PVC. All fittings should be Schedule 80. I have
included a sketch of a typical riser and of the pump configuration.
SPECIAL REQUIREMENTS
This system is designed to use part circle sprinklers. It is critical that the operator refer to
Table 3 of this document for degree of arc settings for each riser to insure that waste will
not be thrown into adjacent ditches, ect. Each P 100 gun will have degree of arc settings
below the swivel point on the gun. Please refer to manuals provided by the irrigation
supplier for setup procedures.
The system operator should never set up both guns on the same lateral line. The pump
used in this system is designed for a specific flowrate and TDH. If more than one gun is
used on any one lateral, the desired gun pressure may not be acheived.
SYSTEM STARTUP
The system operator should contact either the irrigation supplier or the irrigation designer
to assist with the initial startup of this system.
CALIBRATION
Please refer to calibration material provided.
WINTERIZATION
To protect this system from freezing, disconnect the gun assembly from the riser and
drain. Store gun in a protected area. Disconnect both suction and discharge hoses from
the pump and drain.

be fabricated in almost any configuration. Some epoxy coated fittings
include stacks and hydrants as an integral part of the fitting.
Occasionally it may be necessary to connect PVC plastic pipe to steel
or CA pipe. This connection can be made with a coupling called a
transition or repair coupling. In -line valves can be supplied with
connections to gasket pipe.
Thrust blocking is required for gasket pipe. Most thrust blocks
will be concrete.. Manufacturers recommended thrust blocks at any
change in direction greater than 100. Figure 1-gives an example of
different arrangements for thrust blocks.

INSTALLATION
V ®�
Table 4, (,I:SCR I PTION Of I: hi M1;01'f f:NT hi A Tf. R 1 AL CL A.."$ I It A 1111N\
iDiamond Agricultural PVC Pipe should be assembled and
installed with uniform and continuous support from a firm
base in accordance with the installation procedures provided
in ASTM D2321, and the Installation Guide for PVC Water
Pipe (a "pocket -sized" edition is available from your
representative or from Diamond Plastics Corporation.)
Embedment materials are to be in accordance with soil
classifications listed under Unified Soil Classification
System, ASTM D2487, and ASTM D2488.
Te assemble, clean mating surfaces of the bell, spigot, and
gasket. Apply gasket lubricant (furnished by Diamond
Plastics Corporation) to the entire spigot end up to the
reference mark. Also, apply lubricant to the contact surface
of the gasket.
With the pipt in straight alignment, push the spigot into
the bell up to the insertion line. If a pry bar is used to
apply forcc, the pipe should be protected by placing a board
between the bar and the pipe.
)f norrhal force does not complete the joint, disassemble the
joint and examine the parts to make ce,;ian they are free of
obstructions. Visually inspect the completed joint to insure
the gasket has not been dislodged.

Field Calibration Procedures
for Animal Wastewater Application Equipment
STATIONARY
SPRINKLER
IRRIGATION SYSTEM
General Guidelines
Land application equipment used on animal production farms must be field
calibrated or evaluated in accordance with existing 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 operators have been provided calibration and adjustment
guidance for all land application equipment. The rules apply to irrigation sys-
tems as well as all other types of liquid, slurry, or solid application equipment.
Information presented in manufacturers' charts are based on average
operating conditions for relatively new equipment. Discharge rates and appli-
cation rates change over time as equipment ages and components wear. As a
result, equipment should be field calibrated regularly to ensure that applica-
tion rates and uniformity are consistent with values used during the system
design and given in manufacturers' specifications. Field calibration is a simple
procedure involving collection and measurement of the material being
applied at several locations in the application area. This publication con-
tains step-by-step guidelines for field calibration of stationary sprinkler
irrigation systems.
Operating an irrigation system differently than
assumed in the design will alter the application rate,
uniformity of coverage, and subsequently the appli-
cation 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 in-
crease in the nozzle opening, which will increase the
discharge rate while decreasing the wetted diameter.
Clogging of nozzles or crystallization of main lines
can result In Increased pump pressure but reduced
flow at the sprinkler. Plugged intakes willireduce
operating pressure. An operating pressure below
design pressure greatly reduces the coverage diameter
and application uniformity. Field calibration helps
ensure that nutrients from animal waste are applied
uniformly and at proper rates.
The calibration of a stationary sprinkler irrigation
system involves setting out collection containers,
operating the system, measuring the amount of
wastewater collected In each container, and then

computing the average depth of application (applica-
tion volume) and application uniformity,
An in -line flow meter installed in the train
Irrigation line provides a good estimate of the total
volume pumped from the lagoon during each Irriga-
tion 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 formula:
Average application depth (inches) =
Volume pumped (gallons)
27,154 (gal/ac-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 area.Under normal operat-
ing conditions, application depth decreases towards
the outer perimeter of the wetted diameter. Station-
ary sprinkler systems are designed to have overlap of
50 to 65 percent of the wetted sprinkler diameter to
compensate for the declining application along the

Field Calibration Procedures
for Animal Wastewater Application Equipment
outer perimeter. When operated at the design pres-
sure, this overlap results in acceptable application
uniformity.
When operated improperly, well -designed systems
will not pro%ide 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 accept-
able, 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 uniformity.
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 unifor-
mity. Standard rain gauges work best and are recom-
mended because they already have a graduated scale
from which to read the application depth.
Fans, plastic buckets, jars, or anything with a
uniform opening and cross section can be used,
provided the container is deep enough (at least 4
inches deep) to prevent splash and excessive evapora-
tion, and the liquid collected can be easily trans-
ferred to a scaled container for measuring. All con-
tainers should be the same size and shape.
All collection containers should be set up at the
same height relative to the height of the sprinkler
nozzle (discharge elevation ). Normally, the top of
each container should be no more than 36 inches
above the ground. Collectors should be located so
that there is no interference from the crop. The crop
canopy 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 a.m. or
after 4 p.m. on days with light wind (less than 5
miles per hour. On cool, cloudy days the calibration
can be performed any time when wind velocity is less
than 5 miles per hour.
General Guidelines for Stationary
Sprinklers
Rain gauges or other collection containers should be
spaced in a grid pattern fully enclosing the "effective"
wetted area defined by the sprinkler spacing. The
most common spacing pattern for stationary sprin-
klers is a square spacing where the distance between
sprinklers is the same as the spacing between laterals.
The spacing between sprinklers and laterals is nor-
mally between 50 to 55 percent of the sprinkler
wetted diameter specified by the manufacturer.
Collection gauges should be placed one-fourth
the lateral line length from the main and no further
apart than one-fourth the wetted sprinkler radius or
effective sprinkler spacing. (For example, if the
effective spacing is 80 feet, spacing between gauges
should be no more than 20 feet).
The grid pattern and number of gauges required
to complete the calibration depends on the pattern
of operating the Irrigation system. The size of the
calibration area should be no less than the "effective"
area of one sprinkler. When sprinklers are arranged in
a rectangular or square pattern with proper overlap,
an "effective area" receives flow from four sprinklers.
Thus, a minimum of four sprinklers should be
included in the calibration.
The reliability of the calibration generally im-
proves as more sprinklers are included in the calibra-
tion area. If all sprinklers contributing flow to the
calibration area are functioning correctly, it is neces-
sary to include only the minimum number of
sprinklers as described in the preceding paragraph.
But, a malfunctioning sprinkler can greatly influence
the calibration results. Its effect on the calibration
depends on the calibration setup and number of
sprinklers being calibrated, the malfunctioning
sprinkler's position within the calibration area, the
direction of the prevailing wind, and the nature of
the malfunction. For these reasons, it is extremely
important to observe the performance of every
sprinkler contributing to the calibration while the
calibration is being performed and to record any
obvious performance irregularities. The more sprin-
klers that can be included in the calibration, the
more representative the calibration results will be of
the entire field and the less influence one malfunc-
tioning sprinkler will have on the calibration results.
The volume (depth) collected during calibration
should be read as soon as a zone or sprinkler is shut
off to minimize evaporation from the rain gauge.
Where a procedure must be performed more than
once, (Setups 3, 4, or 5 described below) containers
should be read and values recorded immediately after
each different set up.
Operating patterns affect collection container
layout and calibration procedures and results. Typical

field. Since stationary big guns should not be oper-
ated "head to head." (two or more sprinklers throw-
ing water on the same area simultaneously); the
procedure must be repeated several times.
Collection gauges may be centered about one gun
sprinkler. This setup requires that the procedure be
performed three times, once while Gun 2 operates,
again when Gun 3 operates, and a third time when
Gun 4 operates. Collection gauges may also be
centered between Gun 2 and 3 or Guns 3 and 4 as
shown in Figure 6. (Actual location depends on the
length of the lateral). In this setup, the procedure
would be performed twice since only two guns or
gun locations contribute to the calibration.
CASE 1. Block Pattern with 2 or more laterals operating simultaneously
(Scenarios shown in Figures 1 and 2)
1. Determine the effective sprinkler area. (Area defined by sprinkler spacing along a lateral multiplied by the
spacing between laterals. (Example: 80 feet by 80 feet are typical for a solid set wastewater system). The
effective sprinkler area is the minimum area to be included in the calibration area. Note: The calibration
area can be more than the effective area of one sprinkler.
2. Determine the necessary spacing between collection gauges (1 /4 the sprinkler spacing). For an effective
sprinkler spacing of 80 feet, the rain gauge spacing should not exceed 20 feet. (80 ft / 4 = 20 ft). Gauges
closest to the sprinklers should be placed a distance of 1/2 the gauge spacing from the sprinkler. For a
gauge spacing of 20 feet, the first row of gauges should be 10 feet from the lateral line or sprinklers.
3. Determine the number of gauges required. (Minimum number is 16.)
Number of gauges =
Calibration area (ft')
Gauge area (ft')
Example: Calibration area = 80 ft x 80 ft= 6400 W
Gauge area = 20 ft x 20 ft = 400 ft'
6400 ft'
Number of gauges = = 16 gauges
400 ft=
4. Set out gauges in a rectangular pattern as shown in Figure 1 or 2, equally spaced at the distance
determined in item 2 (20 feet) within the calibration area.
S. Operate the system for normal operating time for a full cycle. Record the time of operation (duration in

6. Immediately record the amounts collected in each gauge. (Refer to Worksheet No. 1 for an example.)

8. Calculate the deviation depth for each gauge. The deviation depth is the difference between each
individual gauge value and the average value of all gauges (#7). Record the absolute value of each
deviation depth (absolute value means the sign of the number (negative sign) is dropped and all values
are treated as positive). The symbol for absolute value is a straight thin line. For example,121 means treat
the number 2 as an absolute value. It does not mean the number 121. Because this symbol can lead to
misunderstandings, it is not used with numbers in the worksheets at the end of this publication. The
symbol is used in formulas in the text.

11. Determine the application uniformity. The application uniformity is often computed using the
mathematical formula referred to as the Christiansen Uniformity Coefficient. It is computed as follows:
U': =
Average depth (#7) — average deviation (#9)
X 100
Average depth (#7)
12.Interpret the calibration results. The higher the index value, the more uniform the application. An index
of 100 would mean that the uniformity is perfect — that the exact same amount was collected in every
gauge.
An application uniformity greater than 75 is excellent for stationary sprinklers.
Application uniformity between 50 to 75 is in the "good" range and is acceptable for wastewater
application.
Generally, an application uniformity below 50 is not acceptable for wastewater irrigation with stationary
sprinklers. If the computed U, is less than 50, system adjustments are required. Contact your irrigation
dealer or Certified Technical Specialist for assistance.

Dear. Sir or Madam:
I 'am writing you per instructions received in a Ietter from Mr. Alan Klimeck dated May 27, 1999
concerning temporary odor rules for swine farms. in his Ietter Mr. Klimeck stated that if I believed
that"ifis'problematic for you to comply with any of these required management practices please send
written documentation by August 1,1999." We believe that it is problematic for our farms to comply
with,iegitirement No. 7. In addition we also question the effectiveness of requirement No. 1 and
believe that both of these rules will have a negligible or adverse effect on odor and could produce
negative impacts on water quality.
Requirement No. 7 states that flush tanks should be covered or the fill pipes should be extended below
the surface of the wastewater of the tank From personal observation, I feel that these tanks and the
way that they fill are not a significant source of odor on a swine farm. By covering or extending the fill
pipes the farm operator will not be able to observe the rate at which the recycle hater fills the tank
This is critical because the tanks are often set up to damp periodically with a timer. If the tanks dump
before they are filled the result is insufficient, water to completely move the manure out of the pit thus
creating more odors from the building. Conversely, if the tank fills before it is time to dump, you risk a
spill via a blocked overflow pipe.

Requirement No. 1 states that the discharge point of the pipe from the buildings shall enter below the
surface of animal wastewater lagoons. This requirement will make it impossible for the operator to
observe what is being discharged from the buildings. A pipe that becomes clogged may go undetected
leading to a back up of recycle water in the pit with the potential to spill out of the building. The
operator also will not be able to detect any unusual discharge such as fresh water from a leak or
malfunction. The added turn in the pipe needed to direct the flow under the lagoon surface could also
increase the chance of a blockage.
Because of these concerns we have not covered or extended the fill pipes on the dump tanks at any of
the farms that we own or manage. We have extended our discharge lutes under the surface of the
lagoons. We have advised our growers to extend their discharge lines but have given them their choice
on how to handle the flush tanks. Most have opted to leave them as is. I have included a list of farms
associated with TDM in your region. This includes farms, which we own, manage, or grow hogs on
Contract for us.
Thank you for your attention to this matter and if you have any questions please feel free to contact me.
Sincerely,
I
