The Waste Utilization table shown below summarizes the waste utilization plan for this operation. This plan provides an estimate of the number of acres of cropland netued to use the
nutrients being produced. The plan requires consideration of the realistic yields of the crops to be grown, their nutrient requirements, and proper liming of applications to maximize nutrient
uptake.
This table provides an estimate of the amount of nitrogen required by the crop being grown and an estimate of the nitrogen amount being supplied by manure or other by-products,
commercial fertilizer and residual from previous crops. An estimate of the quantity of solid and liquid waste that will be applied on each field in order to supply the indicated quantity of
nitrogen from each source is also included. A balance of the total manure produced and the total manure applied is included in the table to ensure that the plan adequately provides for the
utilization of the manure generated by the operation.

The following Lagoon Sludge Nitrogen Utilization table provides an estimate of the number of acres needed for sludge utilization
for the indicated accumulation period. These estimates are based on average nitrogen concentrations for each source, the number of
animals in the facility and the plant available nitrogen application rates shown in the second column.
Lagoon sludge contains nutrients and organic matter remaining after treatment and application of the effluent. At clean out, this
material must be utilized for crop production and applied at agronomic rates. In most cases, the priority nutrient is nitrogen but
other nutrients including phosphorous, copper and zinc can also be limiting. Since nutrient levels are generally very high,
application of sludge must be carefully applied.
Sites must first be evaluated for their suitability for sludge application. Ideally-, effluent spray fields should not be used for sludge
application. If this is not possible, care should be taken not to load effluent application fields with high amounts of copper and zinc
so that additional effluent cannot be applied. On sites vulnerable to surface water moving to streams and lakes, phosphorous is a
concern. Soils containing very high phosphorous levels may also be a concem.

The Available Waste Storage Capacity table provides an estimate of the number of days of storage capacity available at
the end of each month of the plan. Available storage capacity is calculated as the design storage capacity in days minus
the number of days of net storage volume accumulated. The start date is a value entered by the user and is defined as the
date prior to applying nutrients to the first crop in the plan at which storage volume in the lagoon or holding pond is
equal to zero.
Available storage capacity should be greater than or equal to zero and less than or equal to the design storage capacity of
the facility. Ifthe available storage capacity is greater than the design storage capacity, this indicates that the plan calls
for the application of nutrients that have not yet accumulated. If available storage capacity is negative, the estimated
volume of accumulated waste exceeds the design storage volume of the structure. Either of these situations indicates
that the planned application interval in the waste utilization plan is inconsistent with the structure's temporary storage
capacity.

Required Specifications For Animal Waste Management
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 that reaches surface water is
prohibited.
2. There must be documentation in the design folder that the producer either owns
or has an agreement for use of adequate land on which to properly apply the
waste. If the producer does not own adequate land to properly dispose of the
waste, he/she shall provide evidence of an agreement with a landowner, who is
within a reasonable proximity, allowing him/her the use of the land for waste
application. It is the responsibility of the owner of the waste production facility to
secure an update of the Nutrient Management Plan when there is a change in the
operation, increase in the number of animals, method of application, receiving
crop type, or available land.
3. Animal waste shall be applied to meet, but not exceed, the nitrogen needs for
realistic crop yields based upon soil type, available moisture, historical data,
climatic conditions, and level of management, unless there are regulations that
restrict the rate of applications for other nutrients.
4. Animal waste shall be applied to land eroding less than 5 tons per acre per year.
Waste may be applied to land eroding at more than 5 tons per acre per year but
less than 10 tons per acre per year provided grass filter strips are installed where
runoff leaves the field (see USDA, NRCS Field Office Technical Guide Standard
393 - Filter Strips).
5. Odors can be reduced by injecting the waste or by disking after waste application
Waste should not be applied when there is danger of drift from the land
application field.
6. When animal waste is to be applied on acres subject to flooding, waste will be soil
incorporated on conventionally tilled cropland. When waste is applied to
conservation tilled crops or grassland, the waste may be broadcast provided the
application does not occur during a season prone to flooding (see "Weather and
Climate in North Carolina" for guidance).
7. Liquid waste shall be applied at rates not to exceed the soil infiltration rate such
that runoff does not occur offsite or to surface waters and in a method which does
not cause drift from the site during application. No ponding should occur in order
to control odor and flies.
720298 Database Version 3.0 Date Printed: 9/23/2003 Specification Page 1

8. Animal waste shall not be applied to saturated soils, during rainfall events, or
when the soil surface is frozen.
9. Animal waste shall be applied on actively growing crops in such a manner that
the crop is not covered with waste to a depth that would inhibit growth. The
potential for salt damage from animal waste should also be considered.
10. Nutrients from waste shall not be applied in fall or winter for spring planted
crops on soils with a high potential for leaching. Waste/nutrient loading rates on
these soils should be held to a minimum and a suitable winter cover crop planted
to take up released nutrients. Waste shall not be applied more than 30 days prior
to planting of the crop or forages breaking dormancy.
11. Any new swine facility sited on or after October 1,1995 shall comply with the
following: The outer perimeter of the land area onto which waste is applied from
a lagoon that is a component of a swine farm shall be at least 50 feet from any
residential property boundary and canal. Animal waste, other than swine waste
from facilities sited on or after October 1,1995, shall not be applied closer that
25 feet to perennial waters.
12. Animal waste shall not be applied closer than 100 feet to wells.
13. Animal waste shall not be applied closer than 200 feet of dwellings other than
those owned by the landowner.
14. Waste shall be applied in a manner not to reach other property and public
right-of-ways.
15. Animal waste shall not be discharged into surface waters, drainageways, or
wetlands by a discharge or by over -spraying. Animal waste may be applied to
prior converted cropland provided the fields have been approved as a land
application site by a "technical specialist". Animal waste shall not be applied on
grassed waterways that discharge directly into water courses, and on other
grassed waterways, waste shall be applied at agronomic rates in a manner that
causes no runoff or drift from the site.
16. Domestic and industrial waste from washdown facilities, showers, toilets, sinks,
etc., shall not be discharged into the animal waste management system.
720298 Database Version 3.0 Date Printed: 9/23/2003 Specification Page 2

17. A protective cover of appropriate vegetation will be established on all disturbed
areas (lagoon embankments, berms, pipe runs, etc.). Areas shall be fenced, as
necessary, to protect the vegetation. Vegetation such as trees, shrubs, and other
woody species, etc., are limited to areas where considered appropriate. Lagoon
areas should be kept mowed and accessible. Berms and structures should be
inspected regularly for evidence of erosion, leakage, or discharge.
18. If animal production at the facility is to be suspended or terminated, the owner is
responsible for obtaining and implementing a "closure plan" which will eliminate
the possibility of an illegal discharge, pollution, and erosion.
19. Waste handling, structures, piping, pumps, reels, etc., should be inspected on a
regular basis to prevent breakdowns, leaks, and spills. A regular maintenance
checklist should be kept on site.
20. Animal waste can be used in a rotation that includes vegetables and other crops
for direct human consumption. However, if animal waste is used on crops for
direct human consumption, it should only be applied pre -plant with no further
applications of animal waste during the crop season.
21. Highly visible markers shall be installed to mark the top and bottom elevations of
the temporary storage (pumping volume) of all waste treatment lagoons.
Pumping shall be managed to maintain the liquid level between the markers. A
marker will be required to mark the maximum storage volume for waste storage
ponds.
22. Waste shall be tested within 60 days of utilization and soil shall be tested at least
annually at crop sites where waste products are applied. Nitrogen shall be the
rate -determining nutrient, unless other restrictions require waste to be applied
based on other nutrients, resulting in a lower application rate than a nitrogen
based rate. Zinc and copper levels in the soils shall be monitored and alternative
crop sites shall be used when these metals approach excessive levels. pH shall be
adjusted and maintained for optimum crop production. Soil and waste analysis
records shall be kept for a minimum of five years. Poultry dry waste application
records shall be maintained for a minimum of three years.
Waste application records for all other waste shall be maintained for five (5)
years.
23. Dead animals will be disposed of in a manner that meets North Carolina
regulations.

Crop Notes
The following crop note applies to field(s): P1, P2, P3, P4, P5, P6, P7, P8, P9
Small Grain: CP, Mineral Soil, medium leachable
In the Coastal Plain, oats and barley should be planted from October 15-October 30; and rye from October
15-November 20. For barley, plant 22 seed/drill row foot and increase the seeding rate by 5% for each
week seeding is delayed beyond the optimum time. See the seeding rates table for applicable seeding rate
modifications in the current NCSU "Small Grain Production Guide". Also. increase the initial seeding rate
by at least 10% when planting no -till. Oats should be planted at 2 bushels/acre and rye at 1-1 1/2
bushels/acre. Plant all these small grains at 1-1 1/2" deep. Adequate depth control is essential. Review the
NCSU Official Variety "green book" and information from private companies to select a high yielding
variety with the characteristics needed for your area and conditions. Apply no more than 30 Ibs/acre N at
planting. Phosphorus and potash recommended by a soil test can also be applied at this time. The
remaining N should be applied during the months of February -March.
The following crop note applies to field(s): P 1, P2, P3, P4, P5, P6, P7, P8, P9
Bermudagrass: CP, Mineral Soil, Moderately Well Drained.
Adaptation: Well -adapted.
In the Coastal Plain, hybrid bermudagrass sprigs can be planted Mar. 1 to Mar. 31. Cover sprigs 1" to 3"
deep (1.5" optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and wind.
For Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a rate of
30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing conditions.
Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced 1' to 1.5' in row. For
broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime, phosphorus, potassium
and micronutrients to apply preplant and for annual maintenance. Apply 60 to 100 lb/ac N in the
establishment year in split applications in April and July. For established stands apply 180 to 240 lb/ac N
annually in split applications, usually in April and following the first and second hay cuts. Reduce N rates
by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization of Pastures and
Forages in North Carolina for more information or consult your regional agronomist or extension agent for
assistance.

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.
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 lagoon is that which comes from your flushing
(washing) system pipes and the rainfall that hits the lagoon directly.
You should inspect your diversion system for the following:
1. adequate vegetation
2, diversion capacity
3. ridge berm height

Identified problems should be corrected promptly. It is advisable to inspect your system
during or immediately following a heavy rain. If technical assistance is needed to
determine proper solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then
record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will
give you an idea of how much your lagoon level will rise with a certain rainfall amount
(you must also be recording your rainfall for this to work). Knowing this should help in
planning irrigation applications and storage. If your lagoon rises excessively, you may
have an 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 lagoon liquid pH. If the pH falls below
7.0, add agricultural Iime 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 entenng 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
darn. Assuming proper design and construction, the owner has the responsibility for
ensuring structure safety. Items which may lead to Iagoon failures include:
Modification of the lagoon structure ---an example is the placement of a pipe
in the dam without proper design and construction. (Consult an expert in
lagoon design before placing any pipes in dams.)
Lagoon liquid levels ---high levels are a safety risk.
Failure to inspect and maintain the dam.
Excess surface water flowing into the lagoon.
Liner integrity ---protect from inlet pipe scouring, damage during sludge
removal, or rupture from lowering lagoon liquid level below groundwater
table.
NOTE: If lagoon water is allowed to overtop the dam, the moving water will soon cause
gullies to form in the dam. Once this damage starts, it can quickly cause a large discharge
of wastewater and possible dam failure.

OPERATION AND MAINTENANCE PLAN
SHEET 1 OF 2
This lagoon is designed for waste treatment (permanent storage) and
180 days of temporary storage.. The time required for the planned
fluid level (permanent and temporary storage) to be reached may vary
due to site conditions, weather, flushing operations, and the amount
of fresh water added to the system.
The designed temporary storage consists of 180 days storage for:
(1) waste from animals and (2) excess rainfall after evaporation. Also
included is storage for the 25 year — 24 hour storm for the location.
The volume of waste generated from a given number of animals will be
fairly constant throughout the year and from year to year, but excess
rainfall will vary from year to 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 invert of pipets) from
building(s). If the outlet pipe is not installed at the elevation to
begin pumping, a permanent marker must be installed at this elevation
to indicate when pumping should begin. An elevation must be established
to stop pumping to maintain lagoon treatment depth.
Pumping can be started or stopped at any time between these two
elevations for operating convenience as site conditions permit, such as
weather, soils, crop, and equipment in order to apply waste without
runoff or leaching.
Land application of
method of disposal.
center pivot, guns,

waste water is recognized as an acceptable
Methods of application include solid set,
and traveling gun irrigation. Care should be
waste to prevent damage to crops.
The following items are to be carried out:
1. It is strongly recommended that 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 precharging is complete,
flush buildings with recycled lagoon liquid. Fresh water should not
be used for flushing after initial filling.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see attachment)
before land application.
3. Begin temporary storage pump -out of the lagoon when fluid level
reaches the elevation 36.3 as marked by permanent marker. Stop pump -
out when the fluid level reaches elevation 34.3 . This temporary
storage, less 25 yr— 24 hr storm, contains 62957 cubic feet or
470918 gallons.

SHEET 2 OF 2
4. The recommended maximum amount to apply per irrigation is
�... one (1) inch and the recommended maximum application rate is 0.3
.inch per hour. Refer to the waste utilization plan for further details.
5. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
6. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable
outlets.
8. Keep a minimum of 25 feet of grass vegetated buffer around
waste utilization fields adjacent to perennial streams. Waste will
not be applied in open ditches. I)o not pump within 200 feet'of a
residence or within 100 feet of a well. Waste shall be applied in a
manner not to reach other property and public right—of—ways.
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.

180 days of temporary storage.. The time required for the planned
fluid level (permanent and temporary storage) to be reached may vary
due to site conditions, weather, flushing operations, and the amount
of fresh water added to the system.
The designed temporary storage consists of 180 days storage for:
(1) waste from animals and (2) excess rainfall after evaporation. Also
included is storage for the 25 year — 24 hour storm for the location.
The volume of waste generated from a given number of animals will be
fairly constant throughout the year and from year to year, but excess
rainfall will vary from year to 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 invert of pipets) from
building(s). If the outlet pipe is not installed at the elevation to
begin pumping, a permanent marker must be installed at this elevation
to indicate when pumping should begin. An elevation must be established
to stop pumping to maintain lagoon treatment depth.
Pumping can be started or stopped at any time between these two
elevations for operating convenience as site conditions permit, such as
weather, soils, crop, and equipment in order to apply waste without
runoff or leaching.

waste to prevent damage to crops.
The following items are to be carried out:
1. It is strongly recommended that 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 precharging is complete,
flush buildings with recycled lagoon liquid. Fresh water should not
be used for flushing after initial filling.
2. The attached waste utilization plan shall be followed. This
plan recommends sampling and testing of waste (see attachment)
before land application.
3. Begin temporary storage pump -out of the lagoon when fluid level
reaches the elevation 36.3 as marked by permanent marker. Stop pump -
out when the fluid level reaches elevation 34.3 . This temporary
storage, less 25 yr— 24 hr storm, contains 62957 cubic feet or
470918 gallons.

4. The recommended maximum amount to apply per irrigation is
�... one (1) inch and the recommended maximum application rate is 0.3
.inch per hour. Refer to the waste utilization plan for further details.
5. Keep vegetation on the embankment and areas adjacent to the
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
6. Repair any eroded areas or areas damaged by rodents and
establish in vegetation.
7. All surface runoff is to be diverted from the lagoon to stable
outlets.
8. Keep a minimum of 25 feet of grass vegetated buffer around
waste utilization fields adjacent to perennial streams. Waste will
not be applied in open ditches. I)o not pump within 200 feet'of a
residence or within 100 feet of a well. Waste shall be applied in a
manner not to reach other property and public right—of—ways.
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.
