Operation and Maintenance
Hose -Drag
See Emergency Response Plan in case of an emergency leak or failure of frac tank/hose drag
System.
Field Calibration
See "Field Calibration Procedures for Animal Wastewater Application Equipment" for Hose -
Drag Wastewater Equipment for step by step procedure for calibration.
Safety Precautions
See safety precautions provided or available from manufacture of the Cadman manure boom
applicator. This system requires a large tractor to pull hose and system operates under high
pressure. An experienced operator is required to operate system. Working or standing near
hose drag system and pumps could be life threating. Shut down system when near supply lines,
hoses and applicator.
Monitoring during Pumping Activities
Pumping activities shall be monitored closely especially during the start-up phase to insure no
spills or discharges occur. Each time hose -drag system is started, a four wheeler or vehicle will
be used to check all hydrants and the pipeline to insure that everything is working properly.
The pump is equipped with automatic shut-off device to minimize risk of discharge in the event
of a pipe failure.
Waste will either be pumped directly out of a waste pond to hose -drag system or waste will be
truck hauled to a frac tank, then pumped from the frac tank. Typically frac tank will be filled up
and tanker trucks filled up when land application begins. Hose drag system and tanker trucks
will run continuously until frac tank is empty. Then the start-up process is repeated.
Requirements for using Frac Tank
1. Staging area — 14 days (staging areas can only be used a maximum of 14 days without
written Division approval).
2. Tank must be located in or adjacent to the application field on the permittee's property so
that the spillage that occurs when transferring or loading waste happens in the application area
and not next to the roadway, driveway, sidewalk, stream, etc. Locating Inside the application
field would be the preferred location so if there is a spill, there should be a crop available to
slow down the run-off. Tank may not be located in a public right-of-way.

3. SPILL CONTROL PLAN
Locate Frac Tank Staging Area in the application field such that a spill would flow away from any
stream, ditch, waterway, etc. Once tank is filled, check for leakage from the tank. Any spill
shall flow into the application field. If natural topography does not allow this type of location,
grading of site maybe required. All spills shall be spread at agronomic rates in application field.
Box scrape or scrape blade will be likely be used to spread any spillage in application field.
4. Frac Tank shall not located in 100 yr floodplain. All staging areas shall be located significantly
away from streams, waterways and floodplains (Le. greater than 100').
5. Prevent storm water or freshwater inflow into the tank.
6. Meet setbacks - 100' from well, 200' from a residence, not on other property or public right-
of-way
7. Tank has a signal for how full frac tank is filled (for example, a float type marker visible to
tanker operator indicating liquid depth in the frac tank).
8. Prevent leachate and spillage run-off —Any leachate or spillage shall be cleaned up
immediately (same day) and spread at agronomic rates in application field. Usually prior to
moving frac tank, the tank will be cleaned out by using a hose from waste tanker and agitating
the waste water and settled solids in tank. Agitated waste is land applied through drag hose.
Never enter a Frac tank for agitating or cleaning unless property ventilated and wearing the
proper safety equipment.
9. The frac tank shall only be used to spread animal waste and parlor water from the dairy. The
tank shall be designed to hold liquids and used in a manner intended by the manufacture.
10. Contact Information shall be printed on the tank ... name, phone, etc.
ROCKY CREEK DAIRY
178 Holstein Lane, Olin, NC 28660
CONTACT: Dairy @ 704-546-7906
11. Keep valves and piping working properly. Never enter a Frac tank for agitating or cleaning
unless properly ventilated and wearing the proper safety equipment.
12. Must maintain records of the date, amount and location (Example T 20000 or tract name)
of the transfer of waste to the tank. See the location map in waste plan for tracts where frac
tank will be used. Use animal waste form to document this information.

Agitation
Agitation is the most critical operation in maintaining available storage capacity in waste
storage ponds. Agitation ofmanure solids re -suspends settled solids and ensures that most or
all ofthe manure will flow tothe pump inlet. Additionally, the agitation hornogenizesthe
manure mixture and provides amore consistent nutrient content. Samples shall be obtained
for nutrient analysis after waste pond i6well mixed. Prior analysis will heused tQestimate the
present analysis.
Agitation of manure storage facilities releases gases that may increase odor levels and present a
health hazard. Consideration shall be given to weather and wind conditions, time of day, and
day of week to minimize the possibility of odor conflicts while agitating.
System Start Up
Hook-up hose to applicator on tractor and pull to end of field. Crack valve at pump and slowly
remove air from supply lines. Once air i5removed, bring system up to operatingpressure and
flovvrate. See monitoring during pumping activities above and manufacture recommendations
of hose -drag applicator for safety precautions.
System Shut Down
Tractor operator will let pump operator know 10close off system. Approximately 5rn|nutes
before field is completely covered with waste, the pump operator shall shut-off pump. Fk}xx

Field Calibration Procedures for Animal
Wastewater Application Equipment
Wastewater
Equipment
Hose -drag -type equipment has gained popularity in recent years for land
application of wastewater' in North Carolina. It offers several advantages
over traditional irrigation systems including odor reduction, nitrogen
conservation, and a relatively high flow rate that cuts the application time.
Hose -drag systems may also be used to apply wastewater to areas not ac-
cessible by traditional irrigation equipment. For more details on hose drag
systems including tables of application depths for various tractor speeds and
equipment widths refer to Extension publication AG-634, Hose Drag Systems
for Land Application of Liquid Manure and Wastewater.
State law requires field calibration of all land application equipment used
on animal production farms. Specialists certifying animal waste manage-
ment plans must also certify that operators have been provided calibration
and adjustment guidance for all land application equipment.
1 Wastewater in this publication refers to both liquid manure and municipal and industrial wastewater.
General Guidelines their discharge points. Since these two basic types
of hose -drag units should be operated with different

This publication explains calibration procedures
for the "low -profile -type" discharge system (Figure
1) and a "boom -type" system. (Figure 2). The two
systems have different spread patterns. The low -
profile -type units discharge close to the ground
either through hooded shrouds or splash plates
and do not spread much beyond their physical
width. They are normally run "edge to edge" in
adjacent passes. Boom -type units discharge from
a slightly higher elevation under slightly more
pressure. Wastewater goes substantially beyond

WASTEWATER EQUIPMENT
Figure 2. Hose drag (boom -type) unit is shown in
these two photos.
The calibration of hose -drag -type equipment
involves:
1. Verifying tractor speed.
2. Measuring flow rate to the equipment.
3. Establishing the effective application width.
4. Measuring the wetted width of a single pass, and
of two adjacent passes for boom -type units in
order to establish an effective width. The wetted
width of boom -type units can vary with boom
height, nozzle pressure, and with adjustment of
splash -plate angle if so equipped.
S. Figuring the average application depth.
6. Comparing the average application depth to the
depth allowed in the waste utilization plan. Vari-
ables (usually tractor speed) are adjusted as needed
so that actual application depth does not exceed
the allowed depth in the approved plan.
Average application depth in inches can be ob-
tained using:
Equation 1:
Flow rate in gallons per minute
Depth =
54.9 x Effective width in feet x Tractor speed in miles per hour
The effective width is the distance between the
centerlines of adjacent passes of the unit. For "low -
profile -type" units, the effective width is essentially the
advertised size of the hose drag systems. Typical widths
for these systems are 8, 10, 12, 15, and 20 feet. Tables
showing applied depth for low -profile -type units of the
above listed widths can be found in Table 1.
For boom -type units, the effective width is deter-
mined in the field by measuring the distance between
centerlines of adjacent passes of the unit. Convert
depths obtained from the equation above or to gal -
Ions per acre by multiplying by 27,154.
Once the application depth has been determined,
the tractor speed may need to be adjusted to meet
requirements in the waste utilization plan. To find
the tractor speed in miles per hour required to apply a
desired application depth, use:
Equation 2:
Flow rate in gallons per minute
Speed =
54.9 x Application depth in inches x Effective width in feet
While application depths up to 1 inch are allowed
in some waste utilization plans, do not apply more
than 0.75 inch during any given application. Limits
set by the waste utilization plan and existing soil
moisture conditions will determine maximum ap-
plication depths.
Flow rates are determined from a flow meter that
may be permanently mounted on the hose -drag unit
upstream of the distribution box or manifold, or
temporarily placed inline with the hose supplying the
hose -drag unit.. If using a hose reel with a temporar-
ily placed meter, position the flow meter between the
hydrant and the reel.

Field Procedure
The field procedure consists of 1) measuring tractor
speed, 2) measuring flow rate, and 3) for boom -type
systems, measuring effective width. Enter collected in-
formation into the appropriate field data sheet (Figure
5 for low -profile type units and Figure 6 for boom -type
units).
Determining Tractor Speed, S
(See Figure 3)
(You will need flags, a stop watch or watch with sec-
ond hand, and a tape measure or measuring wheel).
Repeat steps 2 through 4 below and average the two
measured speeds.
1
pa,

4.
Measure a distance over a relatively flat area where
application will occur. A minimum distance of 100
feet is recommended. Set flags at each end.
Operate tractor with unit and hose attached, but
no wastewater being discharged, to establish a
targeted speed. Record gear range and gear, throttle
setting (rpm), and speedometer reading (if tractor
has a speedometer).
Record the time is takes for the unit to cover the
distance established in step 1. Make sure to start
and stop your watch at either end of the run at a
common point of reference on the unit, such as
when the front axle of the tractor passes the flag.
Calculate tractor speed. Tractor speed in miles per
hour can be calculated by using:
Equation 3:
Distance in feet
Seconds it takes to cover distance x 1.47
If you use a distance of 100 feet, get tractor speed
by dividing 68.18 by the seconds it takes to cover 100
feet.
Determining Flow Rate, Q:
(You will need a flow meter and a stop watch or
watch with a second hand.)
Determine flow rate by either 1) recording the in-
stantaneous flow rate or 2) by using the flow totalizer
and elapsed time. Measure flow rate with the unit in
motion to avoid over -application and after determin-
ing tractor speed as outlined in the previous section.
i 1. Run the system in motion until all air is out of
the mainline and hose, and the flow rate has been
stabilized as shown by the flow rate needle or the
digital readout on flowmeter. If a hose reel is used
to supply wastewater, record the pressure at the
reel. If a reel is not used, record the pressure at the
PUMP.
2a. Record instantaneous flow rate in gallons per min-
ute (gpm).
OR
2b. Subtract beginning flow totalizer reading from
ending flow totalizer reading for a time period not
less than 15 minutes. Convert to gpm by dividing
gallons by elapsed time in minutes. When reading

the totalizer, make sure to note the value of the
last (farthest right) digit. Often this digit indicates
hundreds of gallons, in which case the totalizer
number needs to be multiplied by 100.
Note: Step 2b should be used rather than 2a if
the instantaneous flow rate varies by more than 10
percent after all the air has been purged from the sys-
tem and the flow has stabilized. For flow meters with
needles (normally propeller -type), this is indicated by
a "bouncing" needle.
Determining Effective Width, W (See
Figures 4a, 4b, and 4c):
1. Measure the distance between the fixed nozzles,
Multiply this distance by the number of nozzles
on the boom to obtain the target effective width.
2. For boom -type units (see Figure 2 and Figure 4b)
that spread wastewater an appreciable distance
from the nozzle:
a. Measure the wetted width of a single pass (Wm )
b. /Me7asure the wetted width of two adjacent passes
�^
`''2.)
Repeat steps 2a. and 2b. twice for a total of three
measurements each. Take these measurements at least
25 feet from each other, and average both wetted
width measurements.
The effective width (We) is:
(You will need flags and a tape measure or measur-
Equation 4:
ing wheel.)
Low -profile —type units
For "low -profile" -type units (Figure 1 and Figure
4a) operated with little to no overlap (edge -to -edge),
simply record the advertised width. This width is
roughly the width of the unit.
Boom -type units
It is not as easy to determine the effective width
for boom -type units (Figures 2, 4b, and 4c). To
achieve consistent application uniformity between
adjacent passes, the distance between the nozzles in
adjacent passes should be the same as the fixed dis-
tance between the nozzles on the boom. This requires
a tractor pass spacing equal to the number of nozzles
on the boom times the distance between the nozzles
("N" in Figure 4b) . For the case with two nozzles the
effective width should be 2 x N . If the field mea-
sured effective width calculated in the following steps
differs by more than 15 percent of this target value,
adjust the pass distance.
For boom -type units, the wetted widths measured
in step 2 will depend upon nozzle pressure, boom
height, and angle of the splash plates. If boom height
and splash plate angle are adjustable, make note of
these settings as an adjustment will alter the wet-
ted width and, therefore, the calibration. Boom -type
units may also be subject to drift, so calibration of
these units should be done in wind speeds of 5 mph
or less.
We = W2m -Wm
The tractor speed, flow rate, and effective width
measurements are used to calculate application depth
in the field data sheet or with Equation 1. Data from
the field data sheet may be used with Equation 2 to
determine the target tractor speed to achieve a desired
application depth.
Interpretation and Adjustments
Compare the calculated application depth against
the depth allowed in the animal waste utilization
plan, and against any problems observed in the field.
If either the application depth measured in the field
is greater than the limit in the waste utilization plan,
or runoff occurs on the field, the application rate is
too high. To reduce the application rate, increase the
tractor speed. The target tractor speed may be calcu-
lated from Equation 2 using the system flow rate and
effective width determined in the field procedure.
If the application rate is less than desired (and
under the permitted limit), reduce tractor speed to
increase the application rate. After adjusting the trac-
tor speed, verify the new speed using the procedure
previously described. In no case should the applica-
tion rate allow ponding or runoff, regardless of the
permitted limit.

width for a 2 nozzle boom example, and c.) field -determined effective width for boom -type hose drag units.
To achieve consistent application uniformity,
boom -type units should be driven such that the dis-
tance between nozzles in adjacent passes is about the
same as the distance between the fixed nozzles on the
boom (see Figure 4). In this case the target effective
width (target W), the distance between the centerline
of the tractor in two adjacent passes, is equal to the
number of nozzles on the boom times the distance
between the fixed nozzles (N). If the field -measured
effective width (W) calculated in Equation 4 differs
by more than 15 percent from the target value, adjust
the pass width.
