The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface andfor 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 eactt 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 nuttier it
content of the waste. Do not apply more nitrogen than the crop can utilize. Soil types are
important as they Rave different infiltration rates, leaching potentials, cation exchange
capacities, and .available water -holding capacities. Normally waste shall not be applied to tend
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 •rnay 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 o

WASTE UTiL► jQN- PLAN
REQUIRED 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.
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 town 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
serum 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).
5 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 titled cropland. When applied to conservation tilled crops or grassland,
the waste may be broadcast provided the application does not occur during a season
prone to flooding. {See "Weather and -Climate in North Carolina" for guidance.)
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 pending 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.
Page 6

REQUIRED SPECIFICATIONS
(continued)
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 wasteshould also be considered.
1 0 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.

#7 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, reefs, etc., shouldbe inspected on a regular
basis to prevent breakdowns, leaks and spilis. A regular maintenance checklist should be
kep on site.
20 Anirnal 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-plartt 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
-nark the maximum storage volume for waste storage ponds.
22 Waste shall be tested within 60 days of utilization and soil shalt be tested at least annually
at crop sites where waste products are applied. Nitrogen shall be the rate -determining
element. Zinc and mapper -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.

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 show 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.

OP-ERATJON & MAINTENANCE PLAN
Proper lagoon 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 a
thunderstorm season in the summertime, This means that at the first sign of plant growth in the
later winter / early spring, irrigation according to a farm waste -management plan -should be done
whenever the land in 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 irrigated 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 fertilized 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 1-0-1 0-10, -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 vegetativegrowth.
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 fitting of the lagoon
and at feast 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
2

loon surface -- took for:
I. 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 or 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 of 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
3

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 S 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 overflow problem from a surface water diversion or there may be seepage into
the lagoon from the surrounding land.
Lagoon Operation
Startup:
I. 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 occur 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 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, end 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.
4

• 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 level. (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 fate summer I 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.
• Don not pump the lagoon liquid level lower than 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 darn 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:
5

• 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 terns will:
• have more nutrients,
-• have more odor, and
• -require more -land to properly use the -nutrients.
Removal techniques:
• Mire a custom applicator.
• Mix the sludge and lagoon liquid with a chopper - agitator impeller pump through large -
bore sprinkler imigation system onto nearby cropland; end 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 draglineor 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 phosphors, 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.
6

The application of sludge wiH 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. pipein 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.

AND MAINTENANCE PLAM
OAGt.1 A. Ur Z
Is 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 mayvary
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 pipe(s) from
buildings). 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 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 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 101.3 as marked by permanent marker. Stop pump -
out when the fluid level reaches elevation 99.4 . This temporary
storage, less 25 yr- 24 hr storm, contains 33631 cubic feet or
251563 gallons.

SHEET 2 OF 2
ended maximum amount to apply per irrigation is
nch and the -recommended maximum application rate is 0.3
h per hour. Refer to the waste utilization plan for further details.
Keep vegetation on the embankment and areas adjacent to theie-
lagoon mowed annually. Vegetation should be fertilized as needed
to maintain a vigorous stand.
b. 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. Do 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 -Hof -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.

ICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS
F€?UNDATIOII PREPARATION:
The foundation area of the lagoon embankment and building pad shall be
cleared of trees, logs, stumps, roots, brush, boulders., sod and rubbish,
Satisfactory disposition will be made of all debris. The topsoil from
the lagoon and pad area should be stripped and stockpiled for use on
the dike and pad areas. After stripping, the foundation area of the
lagoon embankment and building pad shall be thoroughly loosened prior
to placing the first lift of fill material to get a good bond.
EXCAVATION AND EARTHFILL PLACEMENT:
The completed excavation and earthfill shall conform to the lines,
grades-, and elevations shown on the -plans. Earthfill material shall
be free of material such as sod, roots, frozen soil, stones over
6 inches in diameter, and other objectionable material. To the extent
they are suitable, excavated materials can be used as fill. The fill
shall be brought up in approximately horizontal layers not to exceed 9
inches in thickness when loose and prior to compaction. Each layer
will he compacted by complete coverage with the hauling and spreading
equipment or standard tamping roller or other equivalent method.
Compaction will be considered adequate when fill material is observed
to consolidate to the point that settlement is not readily detectible.
NQTE THE SPECIAL REQUIREMENTS FOR PLACEMENT OF LINERS IN THE LINER
SECTION OF THIS SPECIFICATION. The embankment of the lagoon shall be
installed using the more impervious materials from the required
excavations. Construction of fill heights shall include 5 percent for
settlement. Dikes over 15 feet in height and with an impoundment
capacity of 10 acre-feet or more fall under the jurisdiction of the NC
Dam Safety Lain. The height is defined as the difference in elevation
from the constructed height to the downstream toe of the dike.
Precautions shall he taken -during construction to prevent excessive
erosion and sedimentation.
LINER: THE MINIMUM REQUIRED THICKNESS SHALL BE 1.5 ft.
NOTE: LINERS (PARTIAL OR FULL) ARE REQUIRED WHEN THE ATTACHED SOILS
INVESTIGATION REPORT SO INDICATES OR WHEN UNSUITABLE MATERIAL IS
ENCOUNTERED DURING CONSTRUCTION. A TYPICAL CROSS SECTION OF THE LINER
IS INCLUDED IN THE DESIGN WHEN LINERS ARE REQUIRED BY THE SOILS REPORT.
When areas of unsuitable material are encountered, they will be over -
excavated below finish grade to the specified depth as measured
perpendicular to the finish grade. The foundation shall be backfilled
as specified to grade with a SCS approved material tie - CL, SC, CH; .
REFER TO THE SOILS INVESTIGATION INFORMATION IN THE PLANS FOR SPECIAL
CONSIDERATIONS.

dal shall come from an approved borrow area. The
content of the liner material shah be optimum moisture
h relates to that :moisture content when the soil is kneaded
hand it will form- a ball which does not readily separate. Water
l be added to borrow as necessary to insure proper -moisturecontent
g placement of the liner. The moisture content of the liner
sterial shall not be less than optimum water content during placement.
e maximum water content relates to the soil material being too wet
for efficient use of hauling equipment and proper compaction. Proper
compaction of the liner includes placement in 9 inch lifts and
compacted to at least 90 percent of the maximum ASTN D698 Dry Unit
Weight of the liner material. When smooth or hard, the previous lift
shall be scarified and moistened as needed before placement of the next
Lift.
The single most important factor affecting the overall compacted perme-
ability of a clay liner, other than the type of clay used for the
liner, is the efficient construction processing of the compacted liner.
The sequence of equipment use and the routing of equipment in an estab-
lished pattern helps assure uniformity in the whole placement and
compaction process. For Most clay soils, a tamping or sheepsfoot
roller IS the preferable type of compaction equipment.
The soil liner shall be protected from the discharge of waste outlet
pipes. This can be done by using some type of energy di,ssipatortrocks)
or using flexible outlets on waste pipes.
Alternatives to soil liners are synthetic liners and bentonite sealant.
When these are specified, additional construction specifications are
included with this Construction Specification.
CUTOFF TRENCH
A cutoff trench shall be constructed under the embankment area when
shown on a typical cross section in the plans, The final depth of the
cutoff trench shall be determined by observation of the foundation
materials.
VEGETATION:
All exposed embankment and other bare constructed areas shall be seeded
to the planned type of vegetation as soon as possible after construc-
tion according to the seeding specifications. Topsoil should be placed
on areas of the dike and pad to be seeded. Temporary seeding or mulch
shall be used if the recommended permanent vegetation is out of season
dates for'seeding. Permanent vegetation should be established as soon
as possible during the next period of approved seeding dates.
REMOVAL OF EXISTING TILE DRAINS
When tile drains are encountered, the tile will be removed to a minimum
of 10 feet beyond the outside toe of slope of the dike. The tile
trench shall be backfilled and compacted with good material such as
SC, CL, or CH.
