The waste from your animal facility must be land applied at a specified Tate 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 the waste is
to be applied. This waste utilization plan uses nitrogen as the limiting nutrient. Waste should be
analyzed before each application cycle. Annual soil tests are strongly encouraged so that all
plant nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe
manner. 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 precautions, waste may be
applied to land eroding at up to 10 tons per year. Do not apply waste on saturated soils, when it
is raining, or when the surface is frozen. Either of these conditions may result in runoff to
surface waters which is not allowed under DEM regulations. Wind conditions should also be
considered to avoid drift and downwind odor problems. To maximize the value of 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.
The estimated acres needed to apply the animal waste is based on typical nutrient content for
this type of facility, Acreage requirements should be based on the waste analysis report from
your waste management facility. Attached you will find information on proper sampling
techniques, preparation, and transfer of waste samples to the lab for analysis.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
21-1.0217 adopted by the Environmental Management Commission.

Applying the above amount of waste is a big job. You should plan time and have appropriate
equipment to apply the waste in a timely manner
The following acreage will be needed for waste application based on the crop to be grown and
surface application:

NOTE: The applicator Is cautioned that P and K may be over applied while meeting the N
requirements. Beginning in 1996 the Coastal Zone Management Act will require farmers in some
eastern counties of North Caroline to have a nutrient management plan that addresses all nutrients.
This plan only addresses Nitrogen.

THIS TABLE IS NOT NEEDED IF WASTE IS NOT BEING APPLIED BY IRRIGATION, HOWEVER A SIMILAR TABLE
WILL BE NEEDED FOR DRY LITTER OR SLURRY.
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 exceed Elevation *see lagoon design.
Call the local Natural Resources Conservation Service (formerly Soil Conservation Service) or Soil
and Water Conservation District office after you receive the waste analysis report for assistance in
determining the amount per acre to apply and the proper application rate prior to applying the
waste.
Narrative of operation:
Acres shown are irrigated acres. The plan is written as a 2 year rotation of corn, wheat, and
soybeans. It is suggested that the grower split the land evenly between corn and soybeans.

REQUIRED SPECIFICATIONS
Animal waste shall not' reach surface waters of the state by runoff, drift, manmade
conveyances, direct application, or direct discharge during operation or land application,
Any discharge of waste which reaches surface water is prohibited.
2 There must be documentation in the design folder that the producer either owns or has an
agreement for use of adequate land on which to properly apply the waste. If the producer
does not own adequate land to properly dispose of 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 of the Waste Utilization Plan when there is a change in the operation,
increase in the number of animals, method of utilization, or available land.
3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic crop
yields based on soil type, available moisture, historical data, climatic conditions, and level
of management, unless there are regulations that restrict the rate of application for other
nutrients.
4 Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land that is eroding at 5 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.
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 cons ervation'ti [led 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 such that runoff
does not occur offsite or to surface waters and in a method which does not cause drift from
the site during application. No ponding should occur in order to control odor or flies.
Animal waste shall not be applied to saturated soils, during rainfall events, or when the
surface is frozen.

REQUIRED SPECIFICATIONS
(continued)
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 potential for leaching. Waste nutrient loading rates on these soils should be held to a
minimum and a suitable winter cover crop planted to take up released nutrients. Waste
shall not be applied more than 30 days prior to planting of the crop or forages breaking
dormancy.
11 Any new swine facility sited on or after October 1, 1995 shall comply with the following:
The outer perimeter of the land area onto which waste is applied from a lagoon that is a
component of a swine farm shall be at least 50 feet from any residential property boundary
and 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).
12 Animal waste shall not be applied closer than 100 feet to wells.
13 Animal waste shall not be applied closer than 200 feet of dwellings other than those owned
by the landowner.
14 Waste shall be applied in a manner not to reach other property and public right-of-ways.
15 Animal waste shall not be discharged into surface waters, drainageways, or wetlands by
discharge or by over -spraying. Animal waste may be applied to prior converted 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, waste shall be applied at agronomic rates in a
manner that courses 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.

REQUIRED SPECIFICATIONS
(continued)
17 A protective cover of appropriate vegetation will be established on all disturbed areas
-(lagoon embankments, berms, pipe runs, etc,), Areas shall be fenced as necessary to
protect the vegetation. Vegetation such as trees, shrubs, and other woody species, etc.,
are limited to areas where considered appropriate, Lagoon areas should be kept mowed
and accessible. Berms and structures should be inspected regularly for evidence of
erosion, leakage or discharge.
18 If animal production at the facility is to be suspended or terminated, the owner is
responsible for obtaining and implementing a "closure plan" which will eliminate the
possibility of an illegal discharge, pollution and erosion.
19 Waste handling structures, piping pumps, reels, etc., should be inspected on a regular
basis to prevent breakdowns, leaks and spills. A regular maintenance checklist should be
kept on site.
20 Animal waste can be used in a rotation that includes vegetables a ' nd 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 animal waste
during the crop season.
21 Highly visible markers shall be installed to mark the top and bottom elevations of the
temporary storage (pumping volume) of all waste treatment lagoons. Pumping shall be
managed to maintain the liquid level between the markers. A marker will be required to
mark the maximum storage volume for waste storage ponds.
22 Waste shall be tested within 60 days of utilization and soil shall be tested at least annually
at crop sites where waste products are applied. Nitrogen shall be the rate -determining
element. Zinc and copper levels in the soil shall be monitored and alternative crop sites
shall be used when these metal approach excessive levels. pH shall be adjusted for
optimum crop production and maintained. Soil and waste analysis records shall be kept
for five years. Poultry dry waste application records shall be maintained for three (3)
years. Waste application records for all other waste shall be maintained for five (5) years.
23
Dead animals will be disposed of in a manner that meets North Carolina regulations.

IRRIGATION SYSTEM DESIGNER
Name: Kraig Westerbeek
Company: Murphy Farms
Address: PO Box 759 Rose Hill, NC
Phone: [phone]
Required Documentation
The following details of design and materials must accompany all irrigation designs:
1. A scale drawing of the proposed irrigation system which includes hydrant locations, pipelines, thrust block locations and buffer areas where applicable.
2. Assumptions and computations for determining total dynamic head and horsepower requirements-
3- Computations used to determine all mainline and lateral pipe sizes.
4- Sources and/or calculations used for determining application rates-
5. Computations used to determine the size of thrust blocks and illustrations of all thrust block configurations required in the system
6. Manufacturer's specifications for the irrigation pump, traveler and sprinkler(s).
7. Manufacturer's specifications for the irrigation pipe and/or USDA-NRCS s6ndard for IRRIGAT10N WATER CONVEYANCE.
8. The information required by this form are the niinimurn requirements. It is the responsibility of the designer to consider all relevant factors at a particular site and
address them as appropriate.
9. Irrigation pipes should not be installed in lagoon or storage pond embankments without the approval of the designer.
NOTE: A buffer strip of 50' or wider must be maintained between the limits of the irrigation system and all
perennial streams and surface waters per NC Statutes.

Narrative of Irrigation System Operation
This irrigation system has been designed to add 5 additional hydrants to the existing system for this farm. Hydrants will
be installed in fields 6, 10, and 11 . In addition, pulls A zin� B in field 7 were shortened from their original length due to the
ditch location to their East. For the pulls mentioned above, the acreage has been calculated using new and expanding farm
criteria. All other pulls, which will not be modified, have acreages calculated using existing 'wetted' acreage criteria.
Field 10 requires SB515 setbacks. These include a 50'setback from the public ROW, 50'from property lines, 100'from wells,
75'from blue line streams, and 200'from residences not owned by the producer.
This design requires that a DOT approved road bore be done as shown on the working drawing.
The producer is familiar with startup, winterization, and R&M requirement for the equipment being used.

There are a number of machines that can be used to prepare the
trench for PVC plastic pipe. Soil types, moisture content, depth of
trench required and type and diameter of pipe must be considered.
Generally chain trenches', wheel trenches, -backho.es, or vibratinq plows
will be " usea for trench preparation. The vibrati'ng plow can only be
used for solvent weld PVC pipe and generally is limited to the smaller
diameter of pipe. Under most conditions the chain- trencher or wheel
trencher will be faster than the backhoe. Where wide trenches for large
pipe are required, the backhoe will be most satisfactory. If soil
conditions permit, long stretches of open trench will expedite pipe
insta)lation. However, if rain is forecast the pipe should be installed
and the trench backfilled. To avoid sharp turns in the line at obstructions,
trenches should be. curved within limits of curvature of the pipe.

INSTALLATION
h
Jiarnond 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 Guidefor 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.
To assemble, clean mating sur-fiaces of the bell, spigot, and
gasket. Apply gasket lubricant (furnished by Diamond
Plastics Corporation) to tile entire spigot end up to the
reference mark. Also, apply lubricant to the contact surface
of the gasket,
Willi the pipe in straight alignment, push the spigot into
the bell up to the insertion line. If a pry bar is used to
qply force, the pipe should be proiecled by placing a board
between the bar and the pipe,
If norrhal force does not complete the joint, disassemble the
joint and examine (he parts (o make ce,Jan they are free of
obstructions. Visually inspect tile compleied joint to insure
(he gasket has not been dislodged.

In cranberry bops where the pipe is not suscepflble to
freezing and heavy equipment is never allowed, the mini-
mum depth of cover may be 6 In for a 6-in diameter pipe
and 12 in for a lwger pipe.
The minimum cover for polyethylene pipe is 6 in but may
be reduced to 2 in where conditions warrant. The minimum
cover for PVC pipe in cranberry bogs, where the pipe is to
be protected from freezing alter winter flooding, shall be 12
in, If the winter flood equals or exceeds 12 in. Where the
winter flood is less than 12 in, the top of the pipe shall be
at least 24 In below the water surface. Solvent -welded joints
shall be used at all connections of PVC pipe where peat
and muck exist in their normal layered pattern. Rubber
gasket Joints may be used toliowing normal bedding proce•
dures where coarse sand or cement layers exist.
At low places on the ground surface, extra fill may be
placed over the pipeline to provide the minimum depth of
cover. The top width of the tilt shall then be no less than 10
ft and the side slopes no steeper than 6:1. if extra protec-
tion is needed at vehicle crossings, encasement pipe.or
other approved methods may be used.
Trench construction. The trench at any point below
the top of the pipe shall be only wide enough to permit
the pipe to be easily placed and joined and to allow the
initial backfiil material to be uniformly placed under,the
haunches and along the side of the pipe. The maximum
trench width shall be 36 in greater than the diameter of
the pipe. It the trench is precision excavated and has a
semicircular bottom that closely fits the pipe, the width
shall not exceed the outside diameter of -the pipe by
more that 10 percent.
The trench bottom shall be uniform so that the pipe lies
on the bottom without bridging. Clods, rocks, and uneven
spots that can damage the pipe or cause nonuniform sup-
port shall be removed.
If rocks, boulders, or any other material that can damage
the pipe are encountered, the trench bottom shall be under-
cut a minimum of 4 in below final grade and filled with bed.
ding material consisting of sand or compacted fine-grained
Soils.
Pipelines having a diameter of 'h through 21,6 in that are
to be placed in areas not subject to vehicular loads and in
soils that do not crack appreciably when dry may be placed
by using "plow -in" equipment instead of conventional
trenching.
Provisions shall be made to insure safe working condi-
tions where unstable soil, trench depth, or other conditions
can be hazardous to personnel working in the trench.
Placement. Care shall be taken to prevent permanent dis-
tortion and damage when handling the pipe during unusu-
ally warm or cold weather, The pipe shall be allowed to
come within a few degrees of the temperature it will have
attar It is completely covered before placing the backifll,
other than that needed for shading, or before connecting
the pipe to other facilities. The pipe shall be uniformly and
continuously supported over its entire length on firm stable
material. Blocking or mounding shall not be used to bring
the pipe to final grade.
For pipe with bell Joints, bell holes shall be excavated in
the bedding material, as needed, to allow for unobstructed
assembly of the joint and to permit the body of the pipe to
be in contact with the bedding material throughout its
length.
Joints and connections. All joints and connections shall
be designed and constructed to withstand the design maxi-
mum working pressure for the pipeline without leakage and
to leave the Inside of the line free of any obstruction that
may tend to reduce its capacity below design requirements.
All fittings, such as couplings, reducers, bends, toes, and
crosses, shall be installed according to the recor -manda-
tions of the pipe manufacturer.
Fittings made of steel or other metals susceptible to cor-
roslon shall be adequately protected by being wrapped with
plastic tape or by being coated with a substance that has
hibh corrosion -preventative qualities. If plastic tape is used,
all surfaces shall be thoroughly cleaned and coated with a
primer compatible with the tape before wrapping.
Threat blocks. Thrust blocks must be formed against a
solid hand -excavated trench wall undamaged by mechani-
cal equipment. They shall be constructed of concrete, and
the space between the pipe and trench wall shall be filled
to the height of the outside diameter of the pipe or as spec-
ified by the manufacturer.
Testing. The pipeline shall be tested for pressure strength,
leakage, and proper functioning. The tests may be per-
formed before backfilling or anytime after the pipeline is
ready for service.
SCS, January 1989

Irrigation Water Conveyance 430-DD-5
Tests for pressure strength and leaks shall be accom-
plished by inspecting the pipeline and appurtenances while
the maximum working pressure is maintained and all joints
and connections are uncovered, or by observing normal
operation of the pipeline after it is put into service. Partial
backfIlls needed to hold the pipe in place during testing
shall be placed as specified in "Initial Backfill." Any leaks
shall be repaired and the system retested.
The pipeline shall be lasted to insure that it functions
properly at design capacity. At or below design capacity
there shall be no objectionable flow conditions. Objecilona-
ble flow conditions shalt include water hammer. continuing
unsteady delivery of water, damage to the pipeline, or detri-
mental discharge from control valves.
Initial backlill. Hand, mechanical, or water packing meth-
ods may be used.
The initial backfill material shall be soil or sand that is
free from rocks or stones larger than 1 in. in diameter. At
the time of placement, the moisture content of the material
shall be such that the required degree of compaction can
be obtained with the backlill method to be used. The initial
backfill material shall be placed so that the pipe will not be
displaced, excessively deformed. or damaged.
II backfilling is done by hand or mechanical means, the
initial fill shall be compacted firmly around and above the
pipe as required to provide adequate lateral support to the
pipe.
It the water packing method is used, the pipeline first
shall be filled with water. The initial backfill before wetting
shall be of sufficient depth to insure complete coverage of
the pipe attar consolidation. Water packing is accomplished
by adding enough water to diked reaches of the trench to
thoroughly saturate the initial backfill without excessive
pooling. After the backfill. is saturated, the pipeline shall
remain lull until after the final backfill is made, The wetted
fill shall be allowed to dry until firm before beginning the
final backlill.
Final backfilt. The final backfitl matbrial shall be free of
large rocks, frozen clods, and other debris greater than 3
In. in diameter. The material shall be placed and spread in
approximately uniform layers so that there will be no
unfilled spaces in the backfill and the backfill will be level
with the natural ground or at the design grade required to
provide the minimum depth of cover after settlement. Poll-
ing equipment shall not be used to consolidate the final
backfill until the specified minimum depth of cover has
been placed.
All special backfilling requirements of the pipe manufac•
turer shall be met.
Basis of acceptance. The acceptability of the pipeline
shall be determined by inspections to check compliance
with all the provisions of this standard with respect to the
design of the line, the pipe and pipe marking, the appune-
nances. and the minimum installation requirements.

Field Calibration Procedures
for Animal Wastewater Application Equipment
HARD HOSE
AND CABLE
TOW TR"ELER
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 op-
erating conditions for relatively new equipment. Discharge rates and applica-
tion 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 involves
collection and measurement of the material being applied at several locations
in the application area. This publication contains 5tep-by-step guidelines for
field calibration of hard hose and cable tow traveler irrigation systems.
Operating an Irrigation system differently than
assumed In the design will alter the application rate,
uniformity of coverage, and subsequently the applica-
tion uniformity. Operating with excessive pressure
results in smaller droplets, greater potential for drift,
and accelerates wear of the sprinkJer 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 crystallization of main lines
can result in Increased PUMP pressure but reduced
flow at the gun. Plugged intakes will reduce operating
pressure. An operating pressure below design pre55ure
greatly reduces the coverage diameter and application
uniformity. Field calibration helps ensure that nutri-
ents from animal waste are applied uniformly and at
properrates.
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, and then computing the
average application volume and application unifor-
mity.
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 Irriga-
tton 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 diameter. Under normal
operating condition5, application depth decreases,,
towards the outer perimeter of'the wetted diameter.
Big gun sprinkler systems typically have overlap
based on a design sprinkler spacing of 70 to 80
percent of the wetted sprinkler diameter to compen-

Field Calibration Procedures
for Animal Wastewater Application Equipment
sate for the declining application along the outer
perimeter, When operated at th ' e design pressure, this
overlap results in acceptable application uniformity.
When operated improperly, well -designed systems
will not provide acceptable application unlformity�
For example, if the pressure is too low, the applica-
tion 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 uniformity.
CollectioH 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 uniformity.
Standard rain gauges work best and are recom-
mended because they already have a graduated scale
from which to read the application depth.
Pans, 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�
talners should be the same size and shape to simplify
application depth computations.
All collection containers should be set up at the
same height relative t ' o 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 anytime when wind velocity is less
than 5 mph.
The volume (depth) collected during calibration
should be read soon after the sprinkler gun cart has
moved onewetted 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 setup.
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 gauge on each end of the row should
extend past the furthest distance the gun will throw
wastewater to ensure that the calibration is perform ' ed
on the "full" wetted diameter of the gun sprinkler.
Multiple rows Increase the accuracy of the calibration.
Containers should be spaced no further apart than
1/16 of the wetted diameter of the gun sprinkler not
to exceed 25 feet. At least 16 gauges should be used in
the calibration. Sixteen gauges will be adequate
except for large guns where the wetted diameter
exceeds 400 feet.
(Maximum recommended spacing between
gauges, 25 feet X 16 = 400 feet.) Gauges should be set
at least one full wetted diameter of throw from either
end of the travel lane, as shown in Figure 1.
The system should be operated such that the
minimum travel distance of the gun cart exceeds the
wetted diameter of throw. Application volumes
should be read as soon as the last gauges stop being
wetted.

14. 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:
Average depth (#9) - Average deviation (#11)
U, Average depth (#9) - X 100
15. Interpret the calibration results. The higher the Index value, the more uniform the application. An index of
1. 00 would mean that the uniformity is perfect — the exact same amount was collected In every gauge.
For travelers with proper overlap and operated in light wind, an'application unlformi�y greater than 85 is
common.
Application uniformity between 70 to 85 Is in the "good" range and Is acceptable for wastewater
application.
Generally, an application uniformity below 70 is considered unacceptable for wastewater Irrigation using
travelers. If the computed Uc is less than 70, system adjU5tMents are required. Contact your irrigation.

Interpret the calibration data and make necessary adjustments.
For travelers with proper overlap and operated in light wind, an application uniformity Coefficient greater than
85 is common.
Application uniformity between 70 to 85 is in the "good" range and is acceptable for wastewater application.
Generally, an application uniformity below 70 is considered unacceptable for wastewater irrigation using
travelers. If the computed U, is less than 70, system adjustments are required. Contact your irrigation dealer or
Certified Technical Specialist for assistance,

Dear Permittee:
Your facility is currently approved for operation under one of the Animal Waste Operation NPDES General Permits, which expire on
July 1, 2007. Due to changes in federal rules, facilities that do not discharge nor propose to discharge may choose whether or not to
retain coverage under an NPDES General Permit. Copies of the draft animal waste operation NPDES general permits and the State
Non -Discharge General Permits are available at htln:Hh2o.enr.state.nc.us/al)s/afou/downloads.htm or by writing or calling:

RE: Sludge Survey Testing Dates
Facility # 82-119
Sampson County
Dear John Blanchard:
RECEIVED
FEBA A 2005
W-FAYEMUIRMOMLOMOR
The Division of Water Quality (DWQ) received your sludge survey information on
January 31, 2005. With your sludge survey, you requested an extension of the sludge survey
requirement for the two lagoons at Whitehorse Farms Inc. Due to the amount of treatment
volume available, and the rate of sludge accumulation for the lagoon DWQ feels that an
extension is not appropriate for Whitehorse Farms Inc
The next sludge survey for the lagoons at Whitehorse Farms Inc. should be performed
before December 31, 2005. The results of the 2005 sludge survey are to be submitted with the
Annual Certification Form that will be due on March 1, 2006.
Thank you for your attention to this matter. If you have any questions, please call me at
[phone].

(Design Capacity)
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 the waste is to be applied This waste utilization plan uses nitrogen as the limiting
nutrient. Waste should be analyzed before each application cycle. Annual soil tests are
strongly encouraged so that all plant nutrients can be balanced for realistic yields of the
crop to be grown.
Several factors are important in implementing your waste utilization plan in order to
maximize the fertilizer value of the waste and to ensure that it is applied -.in an
environmentally safe manner. 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 uttilim. Soil types are important as they have different infiltration rates, lea0iing
potentials, cation exchange capacities, and available water holdiag'capacities.. Normally
waste shall not be applied to land eroding at greater than 5 tons per acre per year. With
special precautions, waste may be applied to land eroding at up to 10 tons per acre.per
,year. Do not apply waste on saturated sods, when it is raining, or when the surface is
-frozen. Either of these conditions may result in ranoffto'surface waters which is not .
:allowed under DEM regulations. Wind conditions should also be consideredto avoid drift
:and downwind odor problems. To maximize the value of 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
di-Jdng will conserve nutrients and reduce odor problems.
The estimated acres needed to apply the animal waste is based on typical nutrient content
for this type of facility. Acreage requirements should be based on the waste analysis
report from your waste management facility. Attached you will find information on
proper sampling techniques, preparation, and transfer of waste samples to the lab for
analysis.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A
NCAC 2R0217 adopted by the Environmental Management Commission

Applying the above amount of waste is a big job. You should plan time and have
.appropriate equipment to apply the waste in a timely manner. L
The following acreage will be needed for waste application based on the crop to be grown
and surface application:
