Re: Earthen Dike And Volume Modifications For A Waste Holding Pond At Th@P9�t_6c �Iotsi ins
Dairy In Davidson County, N.C. DWQ Facility I.D. # 29-20.
Dear Mr. Palmer,
The design for the above referenced storage structure is now complete according to the task given
Environmental Engineering Services. This design is a proposed modification scheme that should allow
your waste storage pond to be certified according to the 0.200 regulations. As I have stated before, the
pond I have designed does not have to be as large as is shown from a regulatory standpoint. However, I
We can make some adjustments on pond size once excavation begins, if this becomes an issue. When the
pond modifications are complete, I will take measurements and develop some as -built drawings as well as
an, as�built er pgrstating the final volumes. I should also be able to issue the proper Technical Specialist
Certifications to accompany the as -built specifications at that time.
Information is being sent to the following persons:
• You are receiving one complete copy of the specifications package.
• Mr. Paul Sherman, P.E. with the Aquifer Protection Section of DWQ in Raleigh will get one copy of
the complete package.
• Ms. Melissa Rosebrock with the Aquifer Protection Section of DWQ in Winston Salem will get one
copy of the complete package.
• Mr. Lloyd Phillips with the Davidson County Soil & Water Conservation District will get one copy of
the complete package.
Please notify me when the earth moving contractors will be ready to begin work since I will need to
perform inspections. Thank -you for your time in this matter and allowing Environmental Engineering
Services to be of assistance.

NOTES ABOUT THIS PROJECT:
' Hi -Roc Holsteins Dairy (or Palmer Dairy) is a well established dairy near the town of Lexington, N.C.

pond and earthen dike modifications necessary for certification. Environmental Engineering Services
' (EES) was not involved with the design of any of the waste management infrastructure at the Hi -Roc
Holsteins Dairy prior to this report.
This dairy has a Certified Animal Waste Management Plan (CAWMP) describing its waste holding
' structures, storage capacities, waste utilization practices, crop plans, etc. Said CAWMP was developed
by the Davidson County S&WCD and the NRCS. Mike Palmer plans to continue to use the existing
CAWMP. Modifications to the existing pond should not significantly alter the existing waste utilization
details of his plan. The modified pond can not be used for any Steady State Live Weight (SSLW)
expansion. Such an expansion would require a new and different waste holding structure.
' Details within this document will show arfgetvalues for pttdzolumebut due to the nature of excavation
type work, the final as -built volume may be different than specified herein. An attempt will be made to
keep the modified pond volume more or less the same as now exists.
' The reader should understand that this design will at times use average or published values for volumetric
predictions. Therefore all values presented should be taken as close approximations rather than for exact
"to -the -inch" values. Given the possible fluctuation in out-of-doors animal waste management systems,
seasonal variations, management changes, etc. using such approximations should be adequate for design.
The farmer/manager however should not exceed the minimum or maximum recommendations for volume
' capacity mentioned in this report so as not to violate the intent of the existing animal waste rules. Each
intensive animal operation and facility operates differently and must be evaluated on its own merit and the
owner/operator's willingness to maintain best management practices or BMP's. It will be completely up
' to the farmer and/or system(s) operator to manage the system in accordance with these plans, to protect
the surface water and groundwater of the State of North Carolina, and to adhere to all rules and
regulations related to animal waste utilization.
' The specifications within this document are acceptable to satisfy a portion of the animal waste
management rules found in the publication titled NCDENR, Division of Environmental Water Quality,
' Title 15A:02H, Section .0200. The reader should refer to this State publication for regulatory details.
The evaluation methodology contained in this document will follow design guidelines found in the U.S.
Natural Resources Conversation Service (NRCS) technical guidelines when applicable and is not intended
' to contradict standard NRCS guidelines or the design criteria of other organizations. The engineer is not
attempting to change certain pond characteristics if those changes would prove cost -to -benefit

BACKGROUND INFORMATION
The Hi -Roc Holsteins Dairy (or Palmer Dairy) is a well established dairy in Davidson County. The farm
' is registered with the NCDENR, Division of Water Quality (DWQ), Aquifer Protection Section (APS)
under the facility I.D. number 29 - 20. Mr, Mike Palmer is the farm owner and manager. The farm is
currently permitted for 275 milk cows and 35 calves. This pond and dike evaluation will relate to these
permitted animal numbers (i.e. no increase in Steady State Live Weight).
Dairy waste'is scraped from the free stall barns into the on -site waste holding pond via a small skid steer
' loader and scrape blade. All of the stored dairy manure is eventually land applied onto near -by crop land.
Typically this land application event is performed by a contract waste applicator two times per year.
There are no other waste storage ponds at this farm on the north side of Palmer Road.

' Hi -Rode Holsteins Waste Storage
Pond Modificaticna. May 2005
tThe original waste storage pond at this dairy was smaller than the pond that exists today. However, the
engineer does not know exactly what volume the original pond held. After an unusually long and wet
' time period during 200212003, Mike Palmer decided to enlarge his waste storage pond so as to safeguard
any liquid from overflowing its banks. Mr. Palmer described this action as an emergency measure. While
Mr. Palmer did discuss this action with some of the local agricultural agencies, ultimately this
enlargement was done without any technical assistance from the Davidson County NRCS or the
S&WCD. Upon discovery of the pond enlargement, Ms. Melissa Rosebrock (an on -farm inspector with
DWQ) contacted Mr. Palmer to notify him that the new dike and pond was expanded without the proper
' documentation from a technical specialist, which made the enlargement a violation of his certified animal
waste permit. Mr. Palmer contacted the local NRCS and S&.WCD representatives for after -the -fact
certification assistance. Because the pond does not meet the current set -back rules from off -site
' residences, these agencies could not render the requested technical assistance.
In May of 2004, Mike Palmer retained the professional services of EES for certification of the recently
' enlarged pond. EES was asked to evaluate the stability of the existing dike and the pond's volumetric
parameters for inclusion as an amendment to the existing CAWMP.
To the engineer's knowledge, there have been no accidental releases of animal waste from the Palmer
Dairy waste storage pond.
REPORT OBJECTIVES
1. To provide the reader a brief background about the animal waste storage pond at the Hi -Roc
Holsteins Dairy. Information about cropping plans, irrigation windows, nitrogen production from
' animal waste, etc. will not be addressed in this report.
2. To measure the existing pond and describe its construction.
3. To evaluate the stability of the earthen dike and make recommendations for stability modifications (if
needed).
4. To estimate the volume of waste storage available in the existing and/or modified pond. The engineer
' will provide details on gallons of storage as well as days of storage.
5. To describe safety issues associated with the maintaining stormwater drains, emergency overflow
points, storm storage requirements, high water marker placement, etc.
' 6. To provide a Technical Specialist Certification for the waste storage pond at this dairy, including
drawings and calculations. Said certifications can be added to the existing CAWMP as an
amendment.
FARM STATISTICS AND INFORMATION
rSite Location
The physical location of the farm parcel is in the east central part of Davidson County approximately S
' miles south of Lexington, N.C. The farm is located on SW623.80 (Palmer Road). Exhibits 1, 2, and 3
show various views of the property.
1 The farm property is bordered by mostly wooded land or farm land with a few residential dwellings close
to the farm. There are many residences in the vicinity of the dairy and the residential growth seems to be
increasing rapidly. There are no historical sites reported within 1 nine of this waste storage pond.
3

' Hi -Rods Holsteins Waste Storage
Paid Modifications. May 2005
The closest residences are just across SR # 2380 from the waste holding pond. Most of these residences
(if not all) were built after the dairy farm was originally established. The distance from the pond and
' nearby residences does not meet the required set -backs for new or expanded facilities. Therefore Hi -Roc
Holsteins Dairy can not use the current pond for expanding herd size.
' Topography and Drainage
In general, the topography at and around the Palmer Dairy consists of rolling hills with all of the drainage
from the site eventually going to�igh vcic- Leak'. A USGS topo map of the area can be seen as Exhibit
' 2. The USGS topographic map containing this information is the`Gtist Mountain�Quadrangiemap(199d-}
Coordinates for the dairy facilities are approximately L no g tu" `de 80 eg es,mil►3 minutes, 3,9, Rseeconds

1 The clasest�7lil-uell ne stream'=that shows up on the USGS quad map is an unnamed stream located about
The Palmer Dairy waste storage pond should not be impacted by 100 year flooding. This was not
' verified with flood insurance maps but is reasonable based on topography, site position, and discussions
with the farmer.
The discharge of animal waste to the surface waters of N.C. is prohibited. Therefore no waste should be
allowed to make its way into the nearby streams and rivers. While no animal farming operation is
immune to wastewater spillage accidents, adhering to the safety guidelines within this document, and
careful waste management, should greatly minimize any such accidents. A sudden dam breach causing a
' significant release of waste is always possible but not very likely when the dike is properly constructed
with clay type soils. Animal manure releases from this pond should be v._M dilute prior to it reaching any
public water supply intake. Aquatic life would be in jeopardy associated with any sudden release of
concentrated dairy waste. The extent of such an accident would depend on the quantity and quality of
the waste spilled. Animal waste discharges from other point sources at this farm are not being evaluated
' by EES.
Animal Waste Related Set -Backs or Buffers
' There are numerous regulations related to set -backs and buffers from intensive livestock operations.
Most of the more stringent set -backs relate to swine production and swine waste. Unfortunately set -back
values are often subject to interpretation since they are date dependent. The engineer has made an
attempt to list the appropriate set -backs below according to his understanding of the .0200 regulations.
Tables 1 and 2 show various buffers or set -backs that apply to swine and dairy operations. Table 1 shows
set -backs from new or expanding facilities and Table 2 shows minimum distances from waste application
' areas. The reader should note that the set -backs shown are dependent on the time the farm was sited.
M-Rock Holsteins was in business before most (if not all) of these set -backs went into effect. Wind
' conditions, neighbor activities, crop growth, temperatures, etc. may require that buffers be increased. The
irrigation operator should be particularly careful to avoid spray drift if irrigating on windy days. Always
protect surface waters near. application sites, even if it means increasing set -back distances.

However the grower should refer to legal counsel and/or regulatory agencies to confirm these opinions
since there is much regulatory confusion about such matters.
' In the opinion of the EES engineer and a representative from DWQ, the Palmer Dairy waste storage pond
is suitable for the currently permitted number of animals but can not be used for expanding herd size or
Steady State Live Weight since it does not meet the required set -backs from residences. An increase in
' SSLW would require a storage pond to be at least 750 feet from a non -farm owned residence. As a word
of caution, it is the owner's responsibility to officially verify any set -backs that are close or questionable.

least 75 feet from public road right-of-ways if using big gum irrigation to avoid unpleasant accidents, especially in windy
conditions. 50 feet from center line is recommended if using a "honey wagon' to broadcast near public road right-of-ways.

from deep groundwater lowering ditches or very steep water ways. Use good judgment and plan this type of activity away
from rain events. Do not irrigate in wet lands. Do not heavily apply waste in valleys which are subject to high rainfall run
off or in wet weather drainage ways. 100 feet buffers from perennial water (i.e. blue line streams) are recommended by the
engineer for all fields where waste is to be applied (if possible).
' Miscellaneous Site Details
There are no down -slope dwellings or structures between the waste storage pond and the nearest creek
' or branch. However, there is a state road running parallel to the southern outside toe of the earthen pond
dike. This fact in itself may make the dike a moderate or high hazard structure. Such a determination on
hazard class is not being addressed in this document.
' Prevailing winds in North Carolina are .typically from the southwest and blow toward the northeast.
There are no high density residential developments, hospitals, schools, or parks immediately northeast of
the Palmer Dairy parcel but some individual dwellings do exist in the nearby community.

' The engineer did not witness the original or subsequent construction of the existing holding pond.
Neither the Davidson County NRCS or the Davidson County Soil and Water Conservation Service had
' any part in the design or construction of the existing holding pond or earthen dike. Conversations with
the contractor who performed the latest dike expansion said he installed a cut-off trench under the dike
and actively compacted the soils. The soils in which the pond is installed are of a clay nature, but there
' was no analytical compaction data available for review.
Typically, the permeability of soils like are at the Palmer Dairy is low, which makes them suitable for
' manure holding structures. The permeability of the clay soils inside a storage pond would be further
reduced due to the nature of the waste substrate and the documented tendency of cow manure to assist in
the sealing of soil surfaces inside ponds.
' From limited on -site viewing, the engineer did not observe any unusual natural or archeological features
at the farm. No endangered or threatened wildlife species were noted, or reported by the owner.
Animal Populations and Related Information
According to Mr. Lloyd Phillips with the Davidson County Soil & Water Conservation District
' (DCS&WCD), the dairy is permitted for 275 milk cows and 35 calves, for a total of 310 head. The total
Steady State Live Weight for this farm is 397,250 pounds (275 cows x 1,400 pounds/cow + 35 calves x
350 pounds = 397,250 pounds). Not all of the cows or calves are in confinement all the time. Only when
' the cows are in confinement do they contribute waste to the on -site storage pond. Table 3 shows a
breakdown of the herd and the waste they are estimated to produce.

pond below.
' For reference, the full -to -overflow volume of the existing waste storage pond has been estimated by EES
to be approximately 2,650,000 gallons. This is considerably more than 6 months of storage for the
Palmer herd size. The original design criteria of the pond is unclear to EES. This structure is reported to
be emptied about two times per year. When the waste is pumped out of the structure, one can see the old
dike outline inside the existing pond.
' The design details below will relate to the proposed modified waste storage pond and not the existing
pond.
Description Of Treatment
Animal waste storage ponds are structures or impoundments that are used to temporarily store liquid
' and/or slurry type wastes. They lack the volume necessary to maintain optimum anaerobic activity,
therefore they are not considered treatment structures. A waste storage pond must contain and store
excess animal waste and storm volumes so as to provide the farmer flexibility in his/her waste utilization
' plan and safety against overflow. Unlike lagoons, waste storage ponds can be pumped dry or almost dry.

' Hi -Rods HotaWms Waste Storago
Pond Modifications, May 2005
Impoundment Shapes and Flows
The east end of the modified waste storage pond will maintain its overall shape. Most of the enlargement
' modifications will take place on the western end. The proposed overall pond surface will be somewhat
pear shaped but irregular. The internal side -wall slopes on the northeast, east, south, and southwest
' corner of the pond will remain as constructed (which are currently between 1.3:1 and 2:1. The internal
side slopes on the new dike portion will be built at a 3:1 slope. Animal waste will continue to be
scraped from the freestalls into the pond using a rubber tired skid steer loader. A concrete ramp serves as
' the dump -off point and will be left in place.
Waste that is scraped into the basin is typically in a thick slurry form, with a likely solids content of
between 2 and 5%. Per the farmer's wishes, the hump in the middle of the pond (part of the old dike)
' will be left in place to act as a solids barrier.
Sludge Holding Capacity
' Solids and sludge are to be removed on a routine basis. No sludge volume is needed in the design.
Design Treatment Volume
' There is no Minimum Design Volume or Design Treatment Volume associated with this pond.
Wastewater And Rainfall Storage
Dairy waste management' systems accumulate water and animal waste over time due to excess water
produced by the animals and from excess rainfall. The days available for excess waste storage depend on
' the volume of waste generated, added rainfall less evaporation, and the farmer's opportunities to empty
the structure. The traditional dairy waste holding pond must be large enough to store the excess water
accumulation until it can evaporate or be emptied via a land application routine.
' Naturally the farmer will not (and can not) land apply animal waste every day or every week because of
convenience, crop growth windows, weather conditions, etc. These factors require there to be storage
' volume built into the pond system to give the farmer safety and flexibility in the land application routine.
The time period for this part of the design can vary between three and six months, but for land application
flexibility, 6 months of storage (or more) is recommended as the safest value to use. Volumetric
' capacities which allow less than 4 months of liquid (or slurry) accumulation may eventually lead to
problems with the safe storage of waste - especially in prolonged wet periods. The temporary storage
volume includes: 1) excess wastes produced by animal production (i.e. feces, urine, bedding, spillage or
' wasted water, and clean-up water); and 2) excess rainfall (less evaporation) entering into the waste
storage system.
The Palmer Dairy waste storage pond receives considerable rainfall run-in from the freestall barn area.
The barn r,,00�fs�are^not:�guttered?so all of the rainfall falling around the freestall barns is transferred to the
storage pond.
' Per the farmer's report, the waste storage pond is emptied two times per year. The farmer's agronomic
plan should correspond to these waste removal events. Agronomic plans and irrigation specifications are
beyond the scope and purpose of this EES report.

amount of rain falling directly onto the pond. This value does not include lot run-off from outside the
pond or flushing water needs. While individual farm manure production may vary, this MRCS value will
be used for estimation purposes. Historical animal waste production data was not available for this
report. Table 3 shows the estimated amount of animal waste slurry going to the storage pond at the Hi -
Roc Holsteins Dairy during the coolest half of the year. This season was used because the cows are in
confinement more in the cool months of the year than they are in the warm months, thus the waste
storage requirements will be higher during this half of the year.

EES has designed the modified pond volume to be similar to the existing pond volume. However, when
construction begins, Mr. Palmer has the flexibility to stop the enlargement if he feels it meets his storage
needs. As -built documentation will be developed by EES to verify final volume and storage capacity.
Rain falling directly onto the pond surface was added into the NRCS waste accumulation values
presented in Table 3. At the Hi -Roc Holsteins Dairy, a considerable amount of water goes into the pond
from the freestall barn area, Once this water is collected in the pond it will be subject to some
evaporation. A best guess estimate for the excess accumulated rainfall for each month of the year
appears in Table 4. Cow manure waste storage ponds'typically have a crusty organic mat on the water
surface. This thick mat is thought by some to reduce the evaporation potential as compared to a free

25 Year - 24 Hour Storm Storage (part of normal freeboard)
At any time in North Carolina there can occur a severe rain producing storm which will deposit
considerable amounts of water quickly. This fact should be considered when designing a lagoon or pond
system and allowances made to accommodate .this extra water. Regulations now require that a new
temporary waste storage ponds or lagoons be designed to hold or contain one 25 year - 24 hour storm

plus a heavy rainfall event in addition to the recommended six months storage requirements mentioned
above.
The standard storm surge allowed in a liquid animal waste system design (i.e. for final stage lagoons or
waste storage ponds) is the 25 year - 24 hour rainfall event. This.storm event is historically different
between the Mountains, Piedmont,. and Coastal Plain and can even vary between neighboring cities.
Climatic data from the U.S. Weather Bureau was available to give the engineer reasonably accurate
information about such rainfall events. The 25 year - 24 hour storm for the Lexington area is about 6.0
inches (see Table 8).

Secondstorm:Anowance_{part of normal.freeboard)
The most recent design criteria established by the NRCS suggests that a second 25 year - 24 hour storm
allowance (sometimes called a' Heavy-RainfaU X1_6wa ec) be made inside the waste storage system before
an overflow would occur. This second storm allowance acts as an additional safety net against effluent
overflow in emergency. situations, especially if unusually heavy rains occur (i.e. rain events greater than
the 25 year - 24 hour storm).
Heavy Rainfall Accumulation or Second Storm Allowance = 321,267 Gallons
Normal Freeboard - TotaIs
Normal freeboard is the extra depth above the maximum "operating" high water level in a waste holding
structure. This extra depth (or extra storage volume) is a safety measure that allows for the storage of at
least two 25 year - 24 hour siorms•.(described above). From the volume vs. depth graph in Exhibit 6, the
engineer has estimated. that the two storms mentioned above would occupy the,, op1;70;t'eet:,(+/-) of

Emergency Spillway Construction
An emergency spillway or overflow is a man-made structure attached to or made part of a liquid
impoundment such as a lagoon,. or a waste holding structure. The emergency spillway allows any liquid
overflows out of the impoundment a path of exit that minimizes damage to the pond dam or embankment.
The idea is that a'controlled release of liquid'is better than a random embankment overflow that could
13

tHi -Rock Holsteins Wastc storage
Pond Modifications. May 2005
' destroy the embankment, potentially cause human or property lo.sses,,and allow additional liquid manure
to escape:
' This emergency spillway should be located on undisturbed, firm soil not easily eroded or on a very solid
surface like bedrock, away from the lagoon dam if possible, or in a position where minimal dam height is
found. Either overflow pipes or earthen overflows may be used, but earthen structures are preferred.
tThe amount of water to be safely passed by an emergency overflow will depend on several factors and,
the degree of safety the designer requires. The emergency spillway should pass the overflow water
' without over -topping the embankments or dam.
The engineer feels that :an intense short duration storm is the appropriate approach to spillway design.
Therefore the engineer decided to use a 100 year m I hour storm for emergency spillway design. Weather
' data for the Lexington area suggests rainfall during this storm event at:
100 year - I hour storm = 3 A inches
' Average flow calculates to be:
3.4 in./hr. x 1.791 acres x 3,630 cu.ft./ac.-in. = 22,105 cu.ft./hr.
' 22,105 cu.ft./hour / 3,600 seconds/hour = 6.14 cu.ft./sec. (cfs)
It is a wise practice to allow for sudden surges or peak flows when designing emergency overflows.
However the earthen overflows are only for emergencies. Without presenting the calculations for peak
flows it.is safe to say that the above flow could be increased by 50 percent to account for a almost any
peak flow situation. The engineer has. assumed an almost instantaneous flow out of the spillway.
' Estimated Peak Flow: 9.2 cubic feet per second (cfs)
' The contractor shall use a flat overflow cut into the rim of the lagoon to convey the overflow. Earthen
overflows shall have sufficient vegetation maintained to prevent scouring of the soil. Recommendations
on the emergency overflow'construction appear in Exhibit 4.
' If the emergency overflow is earthen, a good grass cover shall 'be maintained along its length. The
spillway should be designed so that any overflows would be conveyed well passed the lagoon
construction area and toe of any embankments. A combination of grass, rock rip rap, etc. may used
for the control of erosion in the event of an emergency overflow for earthen overflows. KEEP IN
MIND, THE EMERGENCY OVERFLOW SHOULD NEVER BE USED IF IT CAN BE
' AVOIDED.
The emergency overflow on this structure shall be earthen. Its size has been based on information
obtained in the manual titled "Erosion And Sediment Control Planning And Design Manual", published by
' the North Carolina Department of Environment, Health, and Natural Resources, Land Quality Section. It
is suggested the emergency overflow entrance for the lagoon overflow be 1 foot below the lowest point
' of any earthen embankments around the lagoon perimeter.
The emergency overflow elevations should be verified with a transit after construction.

' The natural base on which the dam shall sit is recommended to have a slope 4:1 or less steep before
construction starts. While during construction the clay soils can dry out or be found to lack sufficient
' moisture to compact. Moisture can be added to the native material if needed for a good bond. If an
upper layer of clay is allowed to dry (on weekends for instance) that layer of soil shall be wetted and
mixed before adding additional lifts when construction resumes. Wetness due to rain shall require the wet
' soil to be removed before resuming construction.
Since it may prove impractical to completely empty the Palmer waste storage pond and work on all of the
' interior surfaces, the engineer has not required any type liner be installed. The east end of the pond will
not be altered, so its interior wili.remain as -is. Because of the manure content inside the pond it will be
impractical to try and put a clay liner on the pond bottom, the engineer can take no responsibility for the
condition of the interior pond surfaces, past or future seepage into the groundwater, existing interior soil
' permeability, etc.
The contractor shall attempt to utilize the highest clay content soils whenever possible for dike repairs
' and cut-off trench construction. These soils should be as rock. and gravel free as possible.
Interior Water Level Management
' In order to facilitate repairs and increase safety, the engineer is specifying that the water level inside the
lagoon be lowered as much as is practical prior to starting dike repairs. Waste removal activities must .
adhere to the conditions mentioned in the farm's most current Certified Animal Waste Management Plan.
' Stormwater Management During Construction
The contractor shall install temporary diversion ditches and terraces to keep rainwater out of the pond,
' cut-off trench, etc. during construction. Rainwater which collects inside the pond and/or cut-off trench
during construction shall be pumped out by the contractor so that soil excavation can resume under dry
conditions. Soggy or saturated soils will not properly compact and must.be removed prior to permanent
' dike building. It will be completely up to the contractor to manage rainwater accumulation 'so as to not
compromise soil compaction, etc.
' Vegetation Removal
Existing Dike Vegetation
' The surface of the existing dike has been allowed to grow up in grass, weeds, and bush. All vegetation
(including any stumps or surface roots) shall be removed prior to dike repairs and earth moving on an as -
needed basis. Grass covers shall remain in place if and where possible.
All soil borrow areas (if needed) shall be cleared of brush and vegetation. Fill and compaction work must
occur on bare ground without .vegetation, rocks, debris, etc. Plugs of dirt in the root ball could cause
' embankment weeping or leakage. A small amount of this work should be done at any one time. Large
stumps (should they exist) shall be dug around to sever roots before extraction, especially if there is any
danger of pulling out a large plug of the dike or causing a leak.
New Dike Vegetation
When the new section of dike is constructed, natural grade can be used to build upon once grass and
vegetation have been removed and if the site is not severely rocky, soft, wet, or steep. The natural grade
shall be developed to remove all trees, shrubs, grasses, boulders, etc. and scarified before fill is added.

Hi -Rock Holsteins Waste Storage
Pond Modifications, May 2005
' This type activity will help assure a good bond between the first layer of fill material and native material.
Moisture can be added to the native material if needed for a good bond.
' Tree stumps must be removed prior to dike construction. The interior of the pond shall have all brush
and grasses removed so soil can be borrowed to construct the dike.
Stumps, laps, and vegetation are to be removed from the site and either hauled off -site or burned or
buried outside of the construction area. Permits for vegetation disposal will be obtained by either the
farm owner or the earth moving contractor.
Drainage Tile Inspection and Repairs
The soils surrounding the existing Palmer Dairy pond and embankment were not found to have
' subsurface drain tile installed. In the event drain pipes would be found during excavation, the following
procedures shall be performed on each pipe inside or under the dike.
• The contractor shall at all times be looking for evidence of drain pipes in the dike.
• Mark the spot where the pipe is discovered so the spot can be identified in the future. This may mean
placing a flagged wooden stake away from the work area but in line with the pipe. If water is found
coming out of or around the pipe, notify the engineer. Serious leaks should be stopped immediately.
The contractor. shall have on hand . materials to plug leaks found in pipes. For leaks around the
outside of pipes the contractor can use granular bentonite clay (such as Hole Plug) or for inside of
pipe leaks the contractor shall use a polyurethane foam sealant that will work to expand and stop
' water flow (such as Great StuM.
• Dig around the pipe to see if it. appears to extend under the dike or if it is only a small segment of
drain pipe dug up from. the original construction. -If at any time water is found coming out of or
around the pipe attempt to stop the leak and notify the engineer
• Dig into the dike far enough so that the pipe can be cut off and the end will be out of the way of
' future earth moving and construction.
• Fill the end of each exposed and cut-off pipe with a neat cement, or a cement and sand mix. The
concrete needs to be sufficiently fluid to flow into the pipe. Make sure the cement completely fills
' the drainage pipe at least 18 inches from the terminal end, making sure all voids are filled. If water is
leaking from the pipe, first stop the water flow as mentioned above. If plugging inside the pipe for
temporary leak stoppage is necessary, make sure the temporary plug is at least 18 inches up inside the
pipe to allow room for the concrete fill.
• Using soil or boards, make a small plug or frame around the end of the pipe and pour a 12 inch x 12
' inch x 12 inch plug at this point. This concrete plug should completely cover the pipe end for 360
degrees so concrete surrounds the terminal end of the pipe. When finished the concrete should be
inside and outside the terminal end' of the pipe.
' • When the concrete has hardened, it can be covered with soil. Make sure to mark the location where
the pipe was found. Do not damage this concrete plug during future dike repairs.
' Core Trench Installation Under The New Portion Of Dike
Once clear of vegetation and any drain pipes have been removed, the contractor and/or engineer shall
' establish elevations and placement of the cut-off trench in the area where the new dike will be
constructed.
A cut-off trench or key shall be installed on the center line of the dike along its longitudinal axis. This
' cut-off trench shall extend up either side of the natural side slopes so as to form a barrier to water
17

Hi -Rock Holsteins Waste storage
Pond Modifications. May 2005
seepage -under the dam and to prevent long term dam movement. The cut off trench shall be sufficiently
wide to allow earth moving machinery to pack all areas of the fill by driving over the fill. Compaction
' with a sheeps-foot roller or vibrating roller is required. Four to six passes shall be made over each 6 or 8
inch lift for compaction before adding another lift. Earthen lift depths can be no greater than the length of
the feet of the sheeps foot roller. It is expected the cut off trench will need to be a minimum of 10 feet
' wide, but this will depend on the packing technique. In no case shall the cut off trench bottom be less
than 8 feet wide.
' The cut off trench shall be taken to a depth sufficient to reach a solid, low permeability clay base, but no
less than 3 feet deep, except where it tapers up to natural grade on the ends. The trench should not be
taken down into a fractured rock base. The trench shall not be taken to subsurface water. The cut oil
' trench shall be inspected for tile drains after it is cut just as a precaution.
The cut off trench shall be backfilled with a relatively impermeable clay material of sufficient moisture
content to pack well via earth moving machinery. Moisture should be between optimum and optimum +
' 4%. Sufficient clay material is available on the Palmer Farm site to provide this material based on soil
investigations. Additional material shall be imported to the site if needed. Cut off trench backfill material
shall be free of boulders, roots, sod, frozen soil, brush, and other unsuitable material. The backfill
' material shall not contain rocks greater than 6 inches in diameter. The dam cut-off trench shall be free of
standing water when backfilling begins.
' Compaction of the cut-off trench shall take place until a 95 percent compaction at optimum moisture is
achieved. This shall be verified at the discretion of the engineer. Moisture may vary + 4% from optimum
if compaction can be achieved. Laboratory results on soil characteristics are not yet available.
Building The New Dike
' The contractor shall tie in the new portion of dike to the existing dike by excavating into the old dike
structure and exposing the existing cut-off trench. Soils in the old dike shall be dug back at an angle to
allow earth moving machinery to enter into the new core trench for adding fill material and for
compaction equipment to have ingress and egress. The contractor shall take whatever means necessary
to tie the old dike into the new dike.
The contractor shall attempt to utilize the highest clay content soils whenever possible for dike and cut-
off trench construction. These soils should be as rock and gravel free as possible. The dike base shall be
made sufficiently wide to allow earth moving machinery to pack all areas of the fill by driving over the fill.
The dike base width shall be calculated by the contractor based on the finished dike height, the top of
rdam width, and the inside and outside slopes. The base of the dike shall be more or less centered over the
cut-off trench.
' The back slope of the dam shall not be steeper than 3:1. A less steep slope is acceptable if dam height is
not compromised. The inside of the new dike (and internal pond sides) shall have a slope no steeper than
3:1 unless authorized by the engineer. The front and back portions of the dam should have a combined
' ratio of at least 6 horizontal to 1 vertical. Exhibit 4 shows more detail on the dike construction. Dike
construction will be checked by the project engineer or a designated NRCS representative. Compaction
checks shall be made as needed and per the engineer's opinion. The top of th& dike shall=be at-least�I=
' feet -wide and.flatland level or made to slope slightly to the outside so rainwater will sheet away from the
pond interior.
18

' Hi -Rock Holsteins Waste Storage
Pend Modifications. May 2005
' The dike shall not be more than 15 feet tall prior to settling, measured from the top of the dam to the
outside toe. Exceeding 15 feet in height will require a permit from the North Carolina Department of
' Environment, Health, and Natural Resources ,(NCDENR) under the Dam Safety Act. See earlier
discussions about dam height.
' A sheeps-foot roller or vibrating roller is required for dike compaction. Four to six passes shall be made
over each 6 or 8 inch lift for compaction before adding another lift. Earthen lift depths can be no greater
than the length of the feet of the sheeps foot roller.
' Compaction of the dam and cut-off trench shall take place until a 95 percent compaction at optimum
moisture is achieved. This shall be verified at the discretion of the construction inspector and/or the
engineer. Moisture may vary + 4% from optimum if compaction can be achieved. Laboratory results on
' soil compaction are not yet available.
An effort shall be made to use uniform materials though out the fill. Alternating layers of dissimilar
' materials is strongly discouraged. When dissimilar materials are used the most impermeable materials
should be used at dam center and on the interior portions of fill. Always eliminate voids during fill
operations.
' All fill layers shall be made to bond. This type activity will help assure a good bond between the first
layer of fill material and native material and subsequent layers of fill. Moisture can be added to the native
material if needed for a good bond. If an upper layer of clay is allowed to dry (on weekends for instance)
' that layer of soil shall be wetted or the dry soil scraped off and mixed before adding additional lifts when
construction resumes. Wetness due to rain shall require the wet soil to be removed before resuming
construction.
' Pond Liners and Interior Finishes as applicable)
� PP )
' When the needed pond volume is achieved the engineer shall inspect the interior to view any soil aspects
that could affect the soil permeability. This is considered the "Macro Permeability" aspect of the
construction soils. Should there be any stratification of the soil layers, changes in soil types, root
' penetrations, cracks, or other possible avenues for liquid outflow, the interior of the pond shall be
scarifiedor disked. This soil feature destruction will help homogenize the lagoon inner face and reduce
the macro permeability factor. As a minimum this disturbed soil shall be packed with a sheeps foot roller
' using a minimum of 3 passes with the roller over the entire lagoon inner area. If hard weathered rock is
encountered it would be better to go directly to the liner material mentioned below and not try to disk the
harder materials. If a soft but stratified material is encountered it should be scarified prior to the liner
' installation. Clay lift thickness shall not exceed the length of the feet of the sheeps foot roller throughout
lagoon construction.
' The contractor shall attempt to utilize the highest clay content soils whenever possible for dike, liner, and
cut-off trench construction. These soils should be as rock and gravel free as possible. Should rock
outcropping, gravel beds, or sandy zones be encountered during pond construction and such areas
t exposed to animal waste by their position below the normal wastewater liquid level, the contractor shall
strive to cover these areas with a good rock free clay, placed in 6 to 8 inch lifts, and compact the clay
with at least 3 passes of a sheeps foot roller per lift. As a rule of thumb, where waste water is deepest
' there should be installed a clay liner at least 1/8 as deep as the typical water depth over that portion of the
her. For example if the high water depth at the "pump -on" level is 24 feet above the clay liner, the liner
shall have a thickness of 3 feet (24 feet /8 = 3 feet), but the engineer reserves the right to alter this
' formula as needed. In no case shall the pond bottom clay liner be less than 2 feet thick. Bentonite clay
19
1

Hi -Rock Holsteins Waste Storage,
Pend Modifications. May 2003
' may be used as a soil additive should the need arise. Final liner thickness shall be left up to the engineer.
The engineer or a soil scientist should make recommendations about soil additives, Liner material should
' be sufficiently moist so proper compaction can be obtained. MRCS criteria for clay liners suggest a
permeability of 1.25 x 10-6 cm/sec or lower, however this is extremely difficult to accurately check in the
field. Liner permeability shall be checked if the clay liner quality is in question.
' Misc. Construction Considerations
' 1. Hi -Roc Holsteins Dairy personnel, project engineer(s), and construction crews will supervise all dam
construction. This shall serve as a quality control measure. The engineer shall have overall
construction authority.
' 2. The engineer recognizes the need to control erosion and sediment transport off -site thus a few
suggestions are being included as part of this package to serve as minimal guidelines for sediment and
erosion control measures. See Exhibits 5 and 7-12 for more details.
3. A pre -construction conference will be required between the engineer, the contractor, and the owners
before construction begins. At the time of this meeting the basic dike and cut-off trench position will
' be established.
4. The reader of this report must recognize that lagoon or pond placement decisions are very important.
Minimizing earth moving and also putting the pond in the best soil types are important considerations.
rSubsurface soil formations can change quickly. On occasion a better or more appropriate site is
discovered during early construction which dictates final pond placement and/or shape. The engineer
reserves the right to make such adjustments in construction so as to maximize pond construction ease
' and safety. Changes to plans will be shown in the as -built drawings if required.
5. The owner of Hi -Roc Holsteins Dairy may wish for additional earth moving work to be done at the
' farm that is unrelated to the earthen lagoon dike repairs. Such work must be authorized by the owner
and supervision of such work will be the responsibility of someone other than the engineer.
6. Soil removed from the pond can be used to construct the dike and cut-off trench if suitable. Sandy,
loamy, or highly organic soils can only be used in the outer 12 inches of surface fill. Topsoil should
be placed on the outer face of the dike for vegetation growing purposes. The highest clay content
soils should be used to make the pond side of the dike.
' 7. When construction is taking place, do only manageable segments of the dike at a time.
' Earth Moving Estimates
Because there will be existing dike repairs and new dike construction at this site, it is impractical to try
' and predict earth moving volumes.

20

Pond Modifications. May 2005
needed. Details on grass planting can be seen below under the Sediment and Erosion Control Section -
Seeding Suggestions.
SEDIMENT AND EROSION CONTROL SUGGESTIONS
' The purpose of sediment and erosion control measures is to confine sediment within to the construction
area. This means the contractor should construct physical barriers, obstacles, or structures to insure
sediment and soil is retained on the construction site. This task includes repairs of disturbed soils, erosion
' scars, and damaged erosion control devices. Grass planting and maintenance are also part of standard
erosion control measures. Selected suggestions and seeding recommendations below were taken in part
from the "Erosion And Sediment Control Planning And Design Manual", published by the North Carolina
' Department of Environment, Health, and Natural Resources, Land Quality Section.
Generally, the contractor should install sediment control traps and sediment fences where appropriate
before or just after construction begins. Plant vegetation in all water conveying ditches as soon as
' possible. Roughen all sloped surfaces and stabilize as soon as possible with vegetation.
The contractor and/or engineers and/or surveyor should mark, flag, or designate the construction areas so
' all understand the intended work areas. This shall take place in the pre -construction conference.
Rainfall run-off from the buildings and/or surrounding areas shall be diverted away from the pond area if
I possible. Specific erosion control devices are shown in the Exhibits portion of this plan.
Sediment removed from sediment control devices shall be stored in stable areas not subject to re-enter the
sediment control devices or escape off site. This also applies to top soil stored or any temporary soil
storage areas. Silt fencing should be installed on the down slope side of stock piled or stored soils and
along the base of earthen embankments.
' Gullies, ditches, moved stone, tarn fence, or similar areas of erosion shall be given immediate attention
and corrective action taken. Control devices that do not seem to be adequately preventing sediment
transport shall be improved to stop soil transport.
' Seeding Suggestions:
There is no more important function for stabilizing a construction site than to plant vegetation soon
as possible after soil disturbance has ended. Sample and test soils for liming and fertilizer
suggestions. Send soil samples to the N.C. Department of Agriculture, Plant, Waste & Tissue Lab,
' 4300 Reedy Creek Road, Raleigh, N.C. 27607. Sample containers can be obtained at the Davidson
County Cooperative Extension Service in Lexington.
Disturbed areas which are to waiting final grading should be seeded with temporary vegetation if
' they will be left idle for more than 15 working days, or if they are subject to severe erosion. The
contractor may wish to seed or re -seed disturbed or undisturbed land with cereal rye if construction
will be taking place in cool weather or with Berman millet if seeding is taking place in summer (See
tTable 16 and Exhibit 10). However, regardless of temporary seeding status, the contractor shall
establish permanent seeding before the job will be considered complete. Do not destroy existing
grass if at all possible.

When final grading is complete, Permanent Seeding will be required. Soil stabilization shall occur
' within 15 working days of final construction or within 60 calendar days. The permanent seeding
shall be performed by the contractor regardless of temporary seeding status. The contractor shall
establish permanent seeding before the job will be considered complete, even if this means working
' on the site during a different and more appropriate time of the year. The engineer will be the final
judge of adequate grass establishment.
The contractor shall use best judgment as to the variety of grass to be planted at the site. A few
recommended grass types are shown as Exhibits 7, 8, and 9. The contractor shall not use Sericea
Lespedeza, Crown Vetch and/or Weeping Lovegrass on dams since these types of vegetation
' encourage burrowing animal habitat, are difficult to maintain, and inhibit visual inspections of the
dike. The contractor shall be responsible for final seeding of the disturbed dike soils. This seeding
shall be of a nature to satisfy the soil type and in accordance with the time of year. This can be a
' seed mixture the contractor chooses, but shall be coordinated with the engineer in advance of
seeding.

' Seeded areas shall be re -seeded if necessary to insure good stands of vegetation are developed and
maintained. Fertilization and mulch shall be installed as necessary.
' Apply seed with a broadcast method, such as a cyclone seeder, drop spreader, drill (in some cases),
etc. Hydro -seeding may be used but is not being specified.
' Rake over all sites to assure seed has been covered and lightly pack in place. Lightly water if water
is available (only enough to moisten soil).
' Mulch Suggestions:
On steep slopes (greater than 3:1) apply approximately 100 pounds of straw per 1000 square feet of
' surface. Cover straw with a netting or jute cover or use some other suitable adhesive material to
hold straw in place. If asphalt is used apply at roughly a rate of 11 gallons per 10.00 square feet of
surface.
' On less steep slopes (less than 3:1) apply approximately 90 pounds of straw per 1000 square feet of
surface. Cover straw with a netting or jute cover or use some other suitable adhesive material to
hold straw in place. Mulch may not be needed on relatively flat surfaces.
The grass lined channels are sometimes difficult to get stabilized because of the velocity of flowing
water. Often water velocities exceeding 2 feet per second on bare soil channels will cause erosion
' scars. in many cases, the previous recommendation is sufficient to get a cover established, however
if not, use an excelsior mat (e.g. Curlex Blanket) to line the channel and secure according to
manufacturers recommendations. Seed all exposed areas and mulch as necessary. Make slopes of
' grass lined channels as gentle as possible. Use drop boxes if necessary to lessen steep slopes.
Silt fencing should be used on the down slope sides of disturbed areas, such as at the toe of the dam,
earthen embankments, and at piles of stored soils if wind -rows are not present. Silt fencing should not
' be used as the only sediment control for large areas of soil disturbance or in grass water ways with
potential for high velocity water streams. Hang silt fencing on wooden or metal posts well anchored into
the soil. Do not allow sediment to flow under loose fitting silt fencing. Anchor the bottoms of slit fences
' in the soil and clean out small sumps or pools just iri front of the fences to allow for sediment build-up.
Liquid heads over 1.5 feet high will likely damage silt fencing.
' Maintain 15 feet vegetative buffers between disturbed areas and property boundaries.
The contractor shall use good judgment and common sense to install sediment and erosion control
' measures where needed. The contractor's judgment will be of the up -most importance.
Grading shall take place on the minimum amount of land necessary to do a specific task. Work should be
done in phases or sections if at all possible; sections stabilized and work started in another portion of the
' site.
The grading contractor shall work on the dike in such a manor that works in cooperation with existing
topography and soil conditions. Questionable soils or rocks shall be addressed with the owners(s) and
the engineer before construction continues.
Exterior earthen bank slopes steeper than 4:1 are more difficult to maintain than slopes more steep.
' Slopes greater than 3:1 can not be safely maintained with mowing equipment.
Soils with high organic matter or frozen soils shall not be used as fill.

Definition Planting rapid -growing annualgrasses, small grains, or legumes to provide in-
itial, temporary cover for crosion control on disturbed areas.
Purpose To temporarily stabilize denuded areas that will not be brought to final grade
for a period of more than 30 working days.
Temporary seeding controls runoff and erosion until permanent vegetation or
other erosion control measures can be established. In addition, it provides
residue for soil protection and seedbed preparation and reduces problems of mud
and dust production from bare soil surfaces during construction.
Conditions Where On any cleared, unvegetated, or sparsely vegetated soil surface where vegcta-
Praetiee Applies uve cover is needed for less than 1 year. Applications of this practice include
diversions, dams, temporary sediment basins, temporary road banks, and top-
soil stockpiles.
1
Planning Annual plants, which sprout and grow rapidly and survive, for only one season,
Considerations are suitable for establishing initial or temporary vegetative cover. Temporary
seeding preserves the integrity of earthen sediment control structures such as
dikes, diversions, and the banks of dams and sediment basins. It can also reduce
the amount of maintenance associated with these devices. For example, the fre-
' quency of sediment basin cicanouts will be reduced if watershed areas, outside
the active construction zone, are stabilized.
' Proper seedbed preparation, selection of appropriate species, and use of quality
seed are as important in this practice as in Practice 6.11, Permanent Seeding.
Failure to follow established guidelines and recommendations carefully may
result in an inadequate or short-lived stand of vegetation that will not control
erosion.
Temporary seeding provides protection for no more than I year, during which
' timcpermancnt stabilization should be initiated.
Specifications Complete grading before preparing seedbeds and install all necessary erosion
' control practices, such as dikes, waterways and basins. Minimize steep slopes
because they make seedbed preparation difficult and increase the erosion
hazard. If soils become compacted during grading, loosen them to a dep th of 6-
: 8 inches using a ripper, harrow, or chisel plow.
1
SEEDBED PREPARATION
Good seedbed preparation is essential to successful plant establishment. A good
seedbed is well -pulverized, loose, and uniform. Where hydroseeding methods
are used, the surface may be Ieft with a more irregular surface of large clods and
stones.
Liming —Apply lime according to soil tcstrecommendations. If thcpH(acidity)
of the soil is not known, an application of ground agricultural limestone at the
6.10.1

'
rate of 1 to 1 1/2 tons/acre on coarse -textured soils and 2-3 tons/acre on fine -
textured soils is usually sufficient. Apply limestone uniformly and incorporate
'
into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed.
Fertilizer —Base application rates on soil tests. When these are not possible,
apply a 10-10-10 grade fertilizer at 700-1,000 lb/acre. Both fertilizer and Iime
should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is
used, do not mix seed and fertilizcr more than 30 minutes before application.
'
Surface roughening —If recent tillage operations have resulted in a loose sur-
face, additional roughening may not be required except to break up large clods.
If rainfall causes the surface to become scaled or crusted, loosen it just prior to
seeding by disking, raking, harrowing, or othersuitable methods. Groove orfur-
'
row slopes steeper than 3:1 on the contour before seeding (Practice 6.03, Sur-
face Roughening).
'
PLANT SELECTION
Sclect 'an appropriate species or species mixture from Table 6.I0a, for seeding
in late winter and early spring, Table 6.10b for summer, and Table 6.1 Oc for fall.
'
In the Mountains, December and January seedings have poor chances of suc-
cess. When it is necessary to plant at these times, use recommendations for fall
'
and a securely tacked mulch.
SEEDING
Evenly apply seed using a cyclone seeder (broadcast), drill, culdpacker seeder,
'
or hydroseeder. Use seeding rates given in Tables 6.10a--6.10c. Broadcast seed-
ing and hydrosccding are appropriate for steep slopes where equipment cannot
be driven. Hand broadcasting is not recommended because of the difficulty in
■
achieving a uniform distribution.
Small grains should be planted no more than 1 inch deep, and grasses and
legumes no more than 1/2 inch. Broadcast seed must be covered by raking or
'
chain dragging, and then lightly firmed with a roller or cultipacker. Hydroseeded
mixtures should include a wood fiber (cellulose.) mulch.
MULCHING
■ The use of an appropriate mulch will help ensure establishment under normal
conditions and is essential to seeding success under harsh site conditions (Prac-
tice 6.14. Mulching). Harsh site conditions include:
• sealing in fall for winter cover (wood fiber mulches are not considered
adequate for this use),
' slopes steeper than 3:1,
• excessively hot or dry weather,
• adverse soils (shallow, rocky, or high in clay or sand), and
• areas receiving concentrated flow.
' If the area to be mulched is subject to concentrated waterflow, as in channels,
anchor mulch with netting (Practice 6.14, Mulching).

Definition Small temporary stone dams constructed across a drainageway.
' Purpose To reduce erosion in a drainage channel by restricting the velocity of flow in
the channel.
'
Conditions Where
This practice may be used as a temporary or emergency measure to limit erosion
Practice Applies
by reducing flow in small open channels. Limit drainage areas to 2 acres or less.
'
Do not use check dams in live streams.
to:
Check dams may be used
• reduce flow in small temporary channels that are degrading, but, where
'
permanent stabilization is impractical due to their short period of useful-
ness;
• reduce flow in small eroding channels where construction delays or
'
weather conditions prevent timely installation of nonerosive liners.
'
Planning
Considerations
Check dams are an expedient way to reduce gullying in the bottom of channels
that will be filled or stabilized at a later date. It is usually better to line the chan-
nel or divert the flow to stabilize the channel than to install check dams.
However, under circumstances where this is not feasible, check dams may be
i
helpful.
Check dams installed in grass -lined channels may kill the vegetative lining if
submergence after rains is too long and/or silting is excessive. All stone and
'
riprap must be removed if mowing is planned as part of vegetative maintenance.
'
Consider the alternative of protecting the channel bottom with materials such
as riprap, concrete, fiberglass mat, or other protective linings in combination
with grass before selecting check dams.
' Design Criteria The following criteria should be used when designing a check dam:
• Ensure that the drainage area above the check dam does not exceed 2
' acres.
• . Keep the maximum height at 2 ft at the center of the dam.
• Keep the center of the check dam at least 9 inches lower than the outer
' edges at natural ground elevation.
• Keep the side slopes of the dam at 2:1 or flatter.
' Ensure that the maximum spacing between dams places the toe of the
upstream dam at the same elevation as the top of the downstream dam
(Figure 6.83a).
' Stabilize overflow areas along the channel to resist erosion caused by
check dams.

• Use 4 to 15-inch stone (N.C. Department of Transportation class 1 or class
B erosion control stone),
• Key the stone into the ditch banks and extend it beyond the abutments a
minimum of 18 inches to avoid washouts from overflow around the dam.
Construction 1. Place stone to the lines and dimensions shown in the plan on a filter fabric
Specifications foundation.
2. Keep the center stone section at least 9 inches below natural ground level
where the dam'abuts the channel banks.
3. Extend stone at least 1.5 ft beyond the ditch banks (Figure 6.83b) to keep
overflow water from undercutting the dam as it re-enters the channel.
4. Set spacing between dams to assure that the elevation at the top of the lower
dam is the same as the toe elevation of the upper dam.
S. Pro=t the channel downstream from the lowest check dam, considering that
water will flow over and around the dam (Practice 6.41, Outlet Stabilization
Structure).
6. Make sure that the channel reach above the most upstream dam is stable.
7. Ensure that channel appurtenances, such as culvert entrances below check
dams, are not subject to. damage or blockage from displaced stones.
Maintenance Inspect check dams and channels for damage after each runoff event.
Anticipate submergence and deposition above the check dam and erosion from
high flows around the edges of the dam. Correct all damage immediately. If
significant erosion occurs between dams, install a protective riprap liner in that
portion of the channel (Practice 6.31, Riprap-lined and Paved Channels).
Remove sediment accumulated behind the dams as needed to prevent damage
to channel vegetation, allow the channel to drain through the stone check dam,
and prevent large flows from carrying sediment over the dam. Add stones to
dams as needed to maintain design height and cross section.

Conditions Where At the outlets of diversions channels slope drains or other runoff conve an-

Below areas that are 5 acres or less.
Where access can be maintained for sediment removal and proper disposal.
In the approach to a storm water inlet located below a disturbed area as part of
an inlet protection system.
Structure life limited to 2 years.
Planning Select locations for sediment traps during site evaluation. Note natural drainage
Considerations divides and select trap sites so that runoff from potential sediment- producing
areas can easily be diverted into the traps. Ensure the drainage areas for each
trap does not exceed 5 acres.
Make traps readily accessible for periodic sediment removal and other nieces-
' sary maintenance. Plan locations for sediment disposal as part of trap site selec-
tion. Clearly designate all disposal areas on the plans.
In preparing plans for sediment traps, it is important to consider provisions to
' protect the embankment from failure from storm runoff that exceeds the design
capacity. Consider nonerosive emergency bypass areas, particularly if there
could be severe consequences from failure. If a bypass is not possible and failure
' would have severe consequences, consider alternative sites.
Sediment trapping is achieved primarily by settling within a pool formed by an
embankment. The sediment pool may also be formed by excavation, or by a
combination of excavation and embankment. Sediment -trapping efficiency is a
function of surface area and inflow rate (Practice 6.61, Sediment Basin). There-
fore, maximize the surface area in the design. Installations that provide pools
with large length to width ratios reduce short circuiting and allow more of the
pool surface area for settling. This optimizes efficiency.
Because well -planned sediment traps are key measures to preventing off -site
sedimentation, they should be installed in the first stages of project develop-
ment.

1.1
Design Criteria Ensure drainage area for a sedimentation trap does not exceed 5 acres.
Storage capacity —Keep the minimum volume of the sediment trap at 1800 i
ft3%acre based on disturbed area draining into the basin. Measure volume below
the crest elevation of the outlet. The volume of a natural sediment trap may be
satisfactorily approximated by the equation:
volume (Its) = 0.4 x -surface area (ft2) x maximum pool depth (ft)
Trap cleanout—Remove sediment from the trap and restore the capacity to
original trap dimensions when sediment has accumulated to one-half the design
depth.
Trap efficiency —Keep the surface area at peak flow as large as possible.
Research by Barfield and Clar (1985) indicates that use of the following equa-
tion will give trap efficiency of 75% for most Coastal Plain and Piedmont soils:
surface area at design flow (acres) = (0.01) peak inflow rate (cfs)
Embankment ---Ensure that embankments for temporary sediment traps do not
exceed 5 ft in height measured at the center line from the original ground sur-
face to the top of the embankment. Additional freeboard may be added to the
embankment height to allow flow through a designated bypass location. Con-
struct embankments with a minimum top width of 5 ft and side slopes of 2:1 or
flatter. Machine compact embankments.
Excavation --Where sediment pools are formed or enlarged by excavation,
keep side slopes at 2:1 or flatter for safety.
Outlet section —Construct the sediment trap outlet using a stone section of em-
bankment Iocated at the low point in the basin. The stone section serves two
purposes: (1).the. top section serves as a nonerosive spillway outlet for flood
flows, and (2) the bottom section provides a means of dewatering the basin be-
tween runoff events.
Stone size --Construct the outlet using well -graded stones with a d5o size of 9
inches (class B erosion control stone is recommended,) and a maximum stone
size of 14 inches. A 1-ft thick layer of 1/2 - 3/4-inch aggregate (N.C. DOT #57
washed stone is recommended) should be placed on the inside face to reduce
drainage flow rate.
Side slopes —Keep the side slopes of the spillway section at 2:1 or flatter. To
protect the embankment, keep the sides of the spillway at least 21 inches thick.
Depth —Keep the crest of the spillway outlet a minimum of 1.5 ft below the set-
tled -top of the embankment.
Protection from piping —Place filter cloth on the foundation below the riprap
to prevent piping. An alternative would be to excavate a keyway trench across
the riprap foundation and up the sides to the height of the dam. r

Weir length and depth —Keep the spillway weir at least 4 ft long and sized to
pass the peak discharge of the 10-yr storm (Figure 6.60a). A maximum flow
depth of 1 ft, a minimum freeboard of 0.5 ft, and maximum side slopes of 2:1
are recommended. Weir length may be selected from Table 6.60a shown for

Construction 1. Clear, grub, and strip the area under the embankment of all vegetation and
Specifications root mat. Remove all surface soil containing high amounts of organic matter
and stockpile or dispose of it properly. Haul all objectionable material to the
designated disposal area.

2. Ensure that fill material for the embankment is free of roots, woody vegeta-
tion, organic matter, and other objectionable material. Place the fill in lifts not
to exceed 9 inches and machine compact it. Over fill the embankment 6 inches
'
to allow for settlement.
3. Construct the outlet section in the embankment. Protect the connection be-
tween the riprap and the soil from piping by using Filter fabric ora keyway cutoff
trench between the riprap structure and the soil.
• Place the filter fabric between the ripmp and soil. Extend the fabric across
the spillway foundation and sides to the top of the dam; or
'
excavate a keyway trench along the centerline of the spillway foundation
extending up the sides to the height of the dam. The trench should be at
'
least 2 ft deep and 2 ft wide with 1:1 side slopes.
4. Clear the pond area below the elevation of the crest of the spillway to facilitate
sediment cleanout.
'
S. All cut and fill slopes should be 2:1 or flatter.
6. Ensure that the stone (drainage) section of the embankment has a.minimum
'
bottom width of 3 ft and maximum side slopes of 1:1 that extend to the bottom
of the spillway section.
7. Construct the minimum finished stone spillway bottom width, as shown on
}
the plans, with 2:1 side slopes extending to the top of the over filled embank- r
ment. Keep the thickness of the sides of the spillway outlet structure at a mini-
mum of 21 inches. The weir must be level and constructed to grade to assure
design capacity.
S. Material used in the stone section should be a well -graded mixture of stone
with a d5o size of 9 inches (class B erosion control stone is recommended) and
a maximum stone size of I4 inches. The stone may be machine placed and the
smaller stones worked into the voids of the larger stones. The stone should be
'
hard, angular, and highly weather -resistant.
9. Ensure that the stone spillway outlet section extends downstream past the toe
of the embankment until stable conditions are reached and outlet velocity is ac-
ceptable for the receiving stream. Keep the edges of the stone outlet section flush
with the surrounding ground and shape the center to confine the outflow stream
(References: Outlet Protection).
10. Direct emergency bypass to natural, stable areas. Locate bypass outlets so
that flow will not damage the embankment.
'
11. Stabilize the embankment and all disturbed areas above the sediment pool
and downstream from the trap immediately after construction (References: Sur-
face Stabilization).
1.2. Show the distance from the top of the spillway to the sediment cleanout
level (one-half the design depth) on the plans and mark it in the field. }

Top of the stake is elevation of max. liquid level, (pump before it gets to that point). Anything above that point is 25 yr

close it out and then he can forget about permits and inspections. He says he may lease it out or start back up some

Melissa,
He knows to renew his permit, whether he did or not I don't know. I set the marker near the push off ramp. Told Mike to
have a metal post or plastic pipe available to use. He never showed up and had no pipe for us to use. Ended up using a
wooden stake that we use on construction projects and set pink flags by marker. Called him and left message he never
called back.

Hey everyone,
Attached is a list of farms that have not submitted their renewal applications. Since we are all trying to save money, I
was hoping that the regions could make a phone call to the farmers on the list before we spend money on -175 certified

The spreadsheet has a tab at the bottom for each region, and a master list for the whole state. I have also attached a

Thanks for the help, and let me know if you have any questions.

Hello Melissa. FYI, I called Mike Palmer and left him a message about my farm visit to stake his waste
storage pond. I will be out of the State for about 2 weeks starting October and told him I would come up
the farm during the last week in October to put the high water stake in his dairy waste storage pond. He
did not call back and verify this was OK, but I am still going up there that week and just do it. I will let
you know when it gets done. Take care..

Hi Melissa.
Mr. Palmer is correct in that I am supposed to show him where to put the
high water level marker in his waste storage pond. The only reason I have
not completed Mike's job is that I am waiting on Mr. John Eddy, P.E. to
complete the dike stability analysis.- All -of my other work is as complete
as I can make it until I get Mr. Eddy's report. I have been trying to get
Mr. Eddy to send me his report for about a year now and he is dragging his
feet - for what reason I do not know. I called him again yesterday 11/20/06
and left him a message to get back in touch with me ASAP. So far, no calls.
Anyway, I will try to get Mr. Eddy on the ball and get the project completed
soon. I will also put up a temporary marker for high water levels.
Let me know if you have any other questions -- and thanks for the notice.

Hello Melissa -
As you know, modifications to Mike Palmer's waste storage pond are more or
less complete. I have had several interruptions that have kept me from
finishing the final details (like total full volume and storm storage
depths). However, I have finishing his project on a top priority right now.
I should have it complete sometime next week. I still have to consult with
Mr. John Eddy about the dike stability issue, but I will see that gets done
ASAP as well. Sorry for the delay, but it is my fault, not Mikes.

Hi Lloyd,
Thanks for your response. Just a couple of notes: if Mike does in fact
change the current volume (i.e. from the volume specified in his most
recent.WUP) then the WUP should be revised to state the new volume and
days of storage.
As far as DWQ is concerned, PLAT does not need to be run yet. Currently,
only NPDES permittees (>700 milkers or >1000 beef) are required to
complete PLAT. I ask our folks about their thoughts on the future (which
is always risky!) and they said that they don't expect to require PLAT
for anyone other than NPDES for the forseeable future. Whether/when NRCS
requires it is a different matter, though (receiving $$ assistance, etc.)
Of course, if the poultry permitting issue is raised again, some farms
in Davidson Co. might be affected. That issue is currently on hold.
Take care. I'll try to keep you posted on things as I go along. Have a
good one!

Hello Melissa - Here is a brief run-down.
1. Construction is more or less complete on the Palmer waste holding pond.
The contractor finished his earth moving work about 1 1/2 to 2 weeks ago.
However, he may have to come back to do a very small amount of earth moving
(I am not sure yet).
2. Mr. Palmer decided to make the final pond volume less than he had before
the retrofit. This is OK since he has plenty of volume to meet the 6 month
storage goal. However, I know during very wet times he will be tested on
water level management.
3. I visited the site last Tuesday (July 12) to collect as -built topo data.
I have not yet crunched the numbers however.
4. I will send the as -built numbers to Mr. John Eddy, P.E. who is helping
out with the dike stability analysis. Once I get his input, I will do the
certification work and as -built drawings. I anticipate all this being
finalized sometime within the next 30 to 45 days, depending on how fast we
all can get our parts done.
Hope this update helps.

Hi Melissa --
Last Friday I met with the contractors who will be performing the earth moving at Mike Palmer's dairy.
They were unable to rent the back -hoe for this week (starting May 24) as planned, so they hope to start
next Monday or Tuesday. You and Paul Sherman are being sent a set of the proposed modifications for
your files. However, I would put more emphasis on the as -built plans that will come once the pond
modifications are complete. Let me know if you have questions. I will be out of the office Tuesday -
Friday of this week.
Thanks.

Hi Melissa --
I talked to Mike Palmer last night and his contractor just finished pumping down the farm's waste
storage pond (Wednesday). He has called in an earth moving contractor, who is supposed to be there
Monday! It so happens I have finished the design of the dike modifications and the volumetric
calculations, so I am for the most part ready to hold the preconstruction meeting with the contractor.
This is slated for Friday May 20. 1 hoped to have a little more time to send in the plans before we began
earth moving, but we do not want the pond to start filling up again until the work is complete, so there is
some urgency in moving forward. If the contractor were to go to a different site first, he might not come
back to Palmer's farm for a month or more.
have developed a specifications package that I plan to send to DWQ. This package shows all of the
"proposed" details associated with pond and dike modifications. Paul Sherman will get a copy, you will
get a copy, and I will send one to Lloyd Phillips with the Davidson County Soil & Water Conservation
District. While this gives everyone the opportunity to see what we "plan" to do, this document is less
useful then the as -built document which shows what was the final outcome. I will be sending out the
plan copies on Monday, May 23 (after I meet with the contractor on Friday).
Overall, the modifications planned are not too complicated. We will be cutting down the existing dike
height and doing some dike reshaping for stability purposes. We will be enlarging the pond to give Mr.
Palmer back a more manageable waste storage volume, but this is for waste management only. He will
not be changing his SSLW beyond the currently permitted number of animals. There will be some new
dike to be constructed associated with the pond enlargement. However, this dike will not be very tall. In
fact, water below the normal freeboard will be below the level of original grade most of the time
along the new dike section.
Please let me know if you have any questions. I will be in the field 98% of next week but I will be
returning phone calls as I can. I will not be getting emails however.
Thanks

Hi Larry,
Thanks for your questions. I appreciate your "pro -active" approach to the situation. In short, the
answers are:
1) No, digging the pond out more without an increase in SSLW is not an expansion and therefore not
subject to current NRCS standards (i.e. minimum distance of 750' from WSP to a residence).
2. Increasing the SSLW beyond his current SSLW of 385,000 lbs. (275 milkers x 1,400 lbs.) would
constitute an expansion per NRCS standards and make the current or new WSP subject to the
current NRCS Standard 313 (February 2002). The standard states that "a new or existing operation
that is enlarging the SSLW must have a minimum distance of 750' from the storage facility to a
residence or place of habitation other than owner or his tenant." As you know, the permit states that
any violation of the CAWMP is a violation of the permit (Section I.3.). The permit also states that
the CAWMP must be consistent with all applicable laws, rules, ordinances, and standards (federal,
state, and local) at the time of siting, design, and certification of the facility (Section 1. 3.).
Mr. Palmer's CAWMP was written for a maximum of 275 milkers for a maximum of 90 days storage.
It is reasonable that he would want to increase the volume of the WSP to allow for a longer storage
period, especially during chronic rain conditions. That said, it may be tempting for him to add more
cattle to the operation when he increases the WSP volume. Please be aware that an increase in SSLW
above 385,000 lbs. or more than 275 milkers would be a violation of this permit and subject him to
enforcement action. If Mr. Palmer wants to increase his operation to more than 275 milkers, he would,
therefore, need to build another WSP that would meet current NRCS standards (i.e. be at least 750'
from a residence).
I am providing the above specifics so that all persons involved, including Mr. Palmer, are aware of the
regulations and implications regarding any increase in the SSLW above 385,000 lbs.
Let me know if you have further questions or concerns.

Hello Lloyd --
Thanks for the phone call and voice message. From you voice mail I think there are two basic
issues we need to know with regards to the Palmer waste holding pond. One deals with replacing
the current volume of the pond without any increase in SSLW and the other involves adding to
the SSLW.
1) If we cut down the existing dike to make it (the dike) more stable, then dig out more
undisturbed soil to keep the volume the same as it is now but do not add any more cows, is this an
expansion? Be it known that his existing pond volume is currently greater than it has to be for his
permitted SSLW. In other words, just in terms of the pond volume as it sits today, it will hold the
waste from more SSLW than stated in his permit.
2) If Mike has the land (i.e. crop yield) needed to meet the needs of 50 more cows (example
only) to his permit and we have this much volume inside the pond now, can we use this volume
as a target for our pond retrofit or would he need to build a new pond for the 50 cows because of
the set -back rules?.
I am sending a copy of this email to Melissa Rosebrock so she too can be thinking about the
matter.

SUBJECT: Animal Waste Storage Pond Expansion
Hi -Rock Holsteins Farm, #29-20
Davidson County
Dear Mr. Palmer:
Several months ago, staff of the Division of Water Quality's Winston-Salem Regional
Office (DWQ-WSRO) performed a compliance inspection at your dairy farm in Davidson
County (see attached inspection report). While onsite, staff observed that the existing waste
storage pond had been enlarged and a new embankment constructed on the west end of the waste
storage pond.
Saying that 2003 was an unusually wet year would be quite an understatement. Like you,
many operators were forced to alter their usual waste application practices. Other operators
removed animals from their facility or transferred the waste from one structure to another. As we
discussed during the compliance inspection, you opted to expand your waste structure to contain
the excessive rainfall that entered the waste structure after accumulating on the concrete cattle
lot. Because of your efforts, the waste in the structure never reached a critical level, and thus, no
overflow or unpermitted discharge occurred.
However, the Guidance Document from the 1217 Group is very clear regarding how
such an expansion should be conducted (Part 3.2 on page 16 of the Seventh Guidance Document,
attached):
"if the facility is not being expanded but modifications to an existing lagoon are needed to
increase its storage or treatment volume, modifications can not be made without meeting current
standards or without updating the existing Certified Animal Waste Management Plan (CAWMP)."
And while the dam visually appeared to be structurally sound on the date of the inspection,
failure to follow the proper procedure prior to expanding a waste structure is a violation of
your CAWMP and cattle permit.
After discussions with several individuals in various agencies, it was determined that the
waste. structure still needs to be certified and incorporated into your current Certified Animal
Waste Management Plan (CAWMP). It is my understanding that you have already contacted a
professional engineer (PE) to certify the design and installation of the waste storage pond (see
highlighted sections on the attached Certification Form). I have also attached a copy of the
Interim NRCS Conservation Practice Standard for Waste storage Ponds to assist you in the
certification process. The following, minimum criteria, must be addressed by the engineer '
order to evaluate certification:�'�

1). Verify that the soils utilized in the expansion are adequate for compaction and
permeability (i.e. does the structure need a liner?)_
2). Verify the slopes (total of 5:1, with neither slope being steeper that 2: 1).
3). Observe the joint between the old and new construction to ensure that it is properly
contacted.
4.) Calculate and document the capacity of the structure.
5.) Determine the stability of the structure.
6.) Have set -back requirements been met?
7.) Does the top width of the dam meet NRCS standards (minimum 10 feet)?
8.) Verify the cut-off trench.
9.) Estimate the amount of freshwater entering the waste structure.
10.) Determine the spillway capacity.
11.) Calculate the volumes for the 25 year/24 hour storm event and heavy rainfall factor.
Waste level markers will need to be re -set.
Our office will be contacting you again sometime in May 2004 to schedule your
compliance inspection for 2004. It is expected that by May you will have made significant
progress towards addressing the criteria listed above and that the expanded structure will soon be
incorporated into the CAWMP. If you have any questions concerning this correspondence or any
other animal waste management issues, please feel free to contact me at [phone].

Revision Five (January 12, 2000). The committee adopted these documents as the
Outside
foundation for this and future guidance documents. This document has been
Links
significantly reformatted and consolidated to enhance readability. Outdated items
were deleted or brought to current status.
This guidance is intended to address the common issues involved in implementing
the animal waste management rules and statutes. Additional guidance will be
provided as necessary to continue to clarify the issues contained in this
memorandum as well as new issues that may arise. The nature of the rules will
require judgment on the part of technical specialists.
Guidance developed by the SB 1217 Interagency Group represent guidelines to
address questions from technical specialists and provides uniform interpretations
regarding requirements of animal waste management rules. However, for areas
where no standards exist, DWQ acknowledges these guidelines as acceptable
criteria to base a Certified Animal Waste Management Plan (CAWMP). Any
requested deviations from this guidance must be considered by DWQ on a case by
case basis to insure that the proposal provides equal or better protection. These
guidelines may also be incorporated by DWQ as permit conditions for an

3. LAGOONS AND WASTE STORAGE STRUCTURES
Committee 3.1 Unused Lagoon/Waste Structure Management and Closure
Technical Lagoons/waste structures that are no longer in use shall be either managed to
Specialists prevent discharge to surface and groundwaters, or decommissioned through a
closure plan. If a discharge does occur from an abandoned animal waste
Guidance management structure, the farm owner is subject to enforcement action by DWQ.
Document In addition, if a water quality or groundwater problem is identified, DWQ will
Outside require proper closure of the structure in addition to enforcement action and
Links possible civil penalty.
For abandoned lagoons and waste structures, proper closure at the earliest
possible date is strongly encouraged. An unclosed lagoon is a potential safety and
environmental danger as well as a liability to the farmer. The closure plan outlining
the closure process shall follow NRCS Technical Standard 709. Proper closure
includes verification by a technical specialist that the work was done according to
standards and specifications, and the completed Animal Waste Storage Pond and
Lagoon Closure Report Form (Appendix 3.1) is submitted to DWQ within 15 days
following completion of the closure. The regional DWQ staff must be notified at
least 24 hours prior to the start of closure. Once the closure is completed and
acknowledged by DWQ, the structure is no longer considered part of the waste
management system, is deleted off of the state database, and may be used for
other purposes such as for irrigation or as a fishpond.
Either a closure plan or the management of an unused lagoon or waste structure
must be included in the CAWMP for facilities operating above threshold as specified
in 2H .0217.
Inactive lagoons or waste structures for deactivated facilities (operations with no
animals or operating below threshold) shall be properly managed to prevent
discharge to surface and groundwaters; however, the waste does not have to be
land applied by a certified animal waste applicator.
3.2 Renovation of Existing Animal Waste Management Systems With No
Expansion
If a facility is not being expanded but modifications to an existing lagoon are
needed to increase its storage or treatment volume, modifications can not be made
without meeting current standards or without updating the existing CAWMP. Only
minor repairs can be made to the structure. Examples would be work to repair
minor erosion or the addition of more soil to the dike to provide greater stability
provided the top of the dike is not raised above the design elevation.
If a new lagoon or waste storage structure is added to an existing treatment
system (no increase in SSLW since February 1, 1993) to provide additional
treatment or storage and is tied into an existing structure (including connection by
pipe or lift station), the existing structure does not need to meet current design
tandards. While it is encouraged that all -existing structures be upgraded to meet
current standards any time there is construction on a site, it is not automatically
required. The technical specialist shall make a determination on the need for
structural upgrades ounng tne eva ua i-on of the o) erall system. If a determination
is made b the technical s ecia is a Axis ru
the connection to the new structures and 4 haLft is ctulCalty_sound, no
u ra es to meet current standards are r ired. In determining the stabili of
the structure, the technica specialist should evaluate an document signs of
p isc a m requent pumpin suggestin ea g ,
slope sta i i y, n s rea ng a ac si e o e y e.
3.3 Lagoons in Wetlands or flood plains
Lagoons shall not be constructed in wetlands or a 100-year flood plain.

3.4 Design Standards
For a lagoon or waste storage structure constructed after February 1, 1993, the
design requirements are contained in the NCAC 2H. 0217 rules, state Statutes, and
NRCS and SWCC technical standards, in effect on the date of the design completion
as documented through NRCS design approval, a professional engineer (PE) seal,
or a CAWMP certification form. (Appendix 2.5A.) Only a PE or NRCS employee with
job approval authority may certify waste structures constructed after February 1,
1993. New construction and/or modification requires certification. Certified designs
for lagoons and waste storage structures in which construction has not commenced
within one year of a design standard change shall be constructed according to the
current design standards regardless of the original design date and require
recertification.
The SWCC has rescinded its animal waste management standards adopted May 2,
1996 effective January 1, 2001. Certifications made after January 1, 2001 of farms
existing prior to May 2, 1996 must meet current NRCS standards. ._CzJe 142-S
3.5 NRCS Policy on Modifications Irror L"_) L5+e 5+0f e
If NRCS provided technical assistance on the original waste structure, technical��
assistance can be provided by NRCS. If NRCS did not provide technical assistance
on the original structure, then assistance generally will not be provided with the
modification because of the time required to adequately assess the design and
construction of the original structure.
3.6 Overflow Pipes Used for Emergency Spillways
Overflow pipe(s) in lagoons are acceptable as a lagoon emergency spillway,
provided they are properly designed for adequate capacity for the design storm
and have a stable inlet and outlet.
3.7 Liquid Levels for Staged Lagoons
In a staged lagoon system where the primary lagoon is gravity fed through a
transfer pipe into a secondary structure, the top of the transfer pipe shall be set
just below the primary lagoon's structural freeboard elevation if the primary
lagoon's 25-year, 24-hour storm requirement is calculated into the second
structure's temporary storage. Pipe size shall be designed to carry the 25-year
storm event without encroaching on the structural freeboard.
3.8 Pumping Markers for Staged Lagoons
Pumping markers are only required in those structures that do not gravity feed
through a free flowing (no valve) transfer pipe into a subsequent structure, and in
those structures which serve as the primary source for land application. For
example, if waste empties from the house into a solids trap, is pumped to lagoon
2, gravity fed to lagoon 3, and then pumped to a solid set system for land
application, both the solids trap and lagoon 3 are required to have markers.
3.9 Requirements for Elevation Pumping Markers
NRCS standards require start and stop pumping markers. Since producers are
required to record freeboard and available storage capacity under an animal waste
general permit, it is highly recommended that they install elevation markers that
will clearly identify minimum and maximum liquid levels as well as a gauge that
enables accurate determination of the distance between the lowest point on the
embankment and the liquid level.
Waste storage structures are designed to be emptied completely and would not
require a minimum elevation marker. Anaerobic lagoons are designed with a
permanent treatment volume, and would require a minimum elevation marker so
the permanent treatment volume is maintained.

CONSERVATION PRACTICE STANDARD
INTERIM
WASTE STORAGE POND
(number)
Code 425
DEFINITION
An impoundment made by excavation or earthfill
for temporary storage of animal or other
agricultural waste.
PURPOSE
To store liquid and solid waste, waste water, and
polluted runoff to reduce pollution and protect
the environment,
CONDITIONS WHERE PRACTICE
APPLIES
This practice applies where: (1) an overall waste
management system has been planned; (2)
temporary storage is needed for waste generated
by agricultural production or processing; (3)
soils are suitable for retaining the waste or can be
sealed; and (4) where livestock are concentrated.
This standard establishes the minimum
acceptable requirements for design, construction,
and operation of waste storage ponds. Under this
standard embankments are limited to an effective
height of 35 ft. or less and to hazard class (a).
This standard does not apply to waste treatment
lagoons or to waste storage structures.
CRITERIA
Location
The waste storage pond shall not be located on a
flood plain unless it is protected from inundation
or damage by a flood event that occurs once
every 25 vears.
Waste Storage Ponds shall be located as close to
the source of waste and as far from neighboring
dwellings or other areas of public use as
practical.
Nonpolluted runoff, from outside drainage areas,
should be excluded to the fullest extent possible.
Non -polluted runoff that can not be excluded
shall be included in the design capacity.
The minimum distance from wells and other
water sources must be in compliance with state
and local ordinances. It is the responsibility of
the designer to ensure that current State and local
distance requirements are met.
Conservation practice standards are reviewed periodically, and updued if needed. To obtain the current version
ofthis standard contact the Natural Resources Conservation Service.

except when special management practices or
techniques permit otherwise. In no case shall a
plan be developed with less than 60 days of
storage capacity.
A means of clearly identifying the level of the
pool at maximum planned volume shall be
installed at each site. A permanent marker shall
be placed in the pool area to clearly indicate the
maximum level of waste that can accumulate
before removal of effluent must be initiated.
With Outside Drainage Area
1. Manure and excess water'
2. Normal precipitation that falls on pond surface
less evaporation on pond surface for the time
which results in the greatest storage
requrements '.
3. Undiverted runoff from drainage area for
normal rainfall during storage period.
4. 25-year, 24-hour precipitation on pond surface.
5. Undiverted runoff from 25-year, 24-hour storm
from drainage area.
425-5
Desisn volume
Waste storage ponds shall store the design
volume plus an allowance for freeboard. Desip
volume is the minimum volume required to store
waste for the planned storage period. It is the
total of the following table.
Without Outside Drainage Area
1. Manure and excess water'.
2. Normal precipitation that falls on pond surface
less evaporation on pond surface the time of year
which results in greatest storage regiuvrements'.
3. 25-year, 24-hour precipitation on pond surface.
'Accumulated during the storage period.
Note: Additional temporary storage may be provided to meet management goals.
Domestic and industrial waste from washdown
facilities, showers, toilets, sinks, etc., shall not be
discharged into the animal waste managment
system.
Cutoff Trench
A cutoff of relatively impervious material shall
be provided under the embankment if necessary
for seepage control. The cutoff shall be located
at or upstream from the centerline of the dam. It
shall extend up the abutments as required and be
deep enough to extend into a relatively
impervious layer or provide for a stable
embankment when combined with seepage
control. The cutoff trench :hall have a bottom
width adequate to accommodate the equipment
used for excavation, backfill, and compaction

be determined by the designer. Access should be
provided to the pipe for rodding in case of
blockage.
Pipes and open inlets that convey waste to the
pond shall be designed and installed in a manner
that will prevent erosion of the pond side slope.
This will be accomplished by (I) extending the
pipe or inlet beyond the slope of the pond, (2)
installing an armoring surface such as rock
riprap or concrete on the slope, or (3) using a
flexible pipe that will conform to the surface of
the slope and safely convey the effluent into the
pond.
Pipes
If any pipes are to be placed through the
embankment, the location and method of
installation shall be approved by the designer of
the embankment or a technical specialist
designated by the Soil and Water Conservation
Commission to design and approve waste storage
ponds. The installation shall be certified by the
inspector.
Emergency Spillway
Waste storage ponds having a maximum design
liquid level of 3 feet or more above natural
ground shall be provided with an emergency
spillway to prevent overtopping. The crest of the
emergency spillway shall be located at the same
elevation as the top of the 25-year, 24-hour storm
storage. The emergency spillway shall be placed
in undisturbed soil when possible. When it must
be placed in fill material, precautions shall be
taken to insure the integrity of the structure.
The emergency spillway shall pass a 25-year, 24-
hour storm without overtopping the embankment.
There shall be a minimum of 1 foot of freeboard
above the designed depth of flow in the
emergency spillway. Where a waste storage
pond empties into another waste storage pond
and the liquid level is positively controlled by an
423-7
adequately sized overflow pipe, no emergencv
spillway is required for the primary waste storage
pond.
Protection
If the pond will create a safety hazard, it shall be
fenced and warning signs posted to prevent
children and others from using it for purposes
other than intended.
A protective cover of vegetation will be
established on all disturbed areas. Temporary
vegetation may be used until permanent
vegetation can be established. Vegetation will be
established in compliance with Critical Area
Treatment standards (342-II) of the Technical
Guide.
The pond shall be fenced, if necessary, to protect
the vegetation.
Erosion and Sediment Control Measures
Plans for waste storage ponds shall include
temporary measures for the control of erosion
and sedimentation during the construction period.
Permanent vegetation will be established on all
disturbed areas.
CONSIDERATIONS
If the embankment is over I5 feet high and
impounds over 10-acre feet of effluent, a permit
must be obtained as required by the North
Carolina Dam Safetv Law.
When siting the waste storage pond due
consideration should be given to access to other
facilities, ease of loading and unloading wastes,
the overall waste management plan, and health
and safety factors. The waste storage pond
should be located so that prevailing winds,
vegetative screening, and building arrangement
minimize odor and visual resource problems.

3.10 Freeboard for Solids Traps
Older swine operations had lagoons that were dug pits (no dike walls) and were
later converted into solids traps with waste pumped to a newer structure(s) to
satisfy retrofit requirements of the waste handling system. These structures are
allowed to operate with less than the one foot structural freeboard and 25-year,
24-hour storm event storage requirement if:
1. a back-up pump with power source is available in the event of equipment
failure to lift waste to a secondary structure,
2. a honey wagon/tanker is available with the capacity to empty the structure,
or
3. a secondary containment structure is available to store the waste.
For exemption from the one -foot structural freeboard requirement, consideration
must be also given to the location of the seasonal high water table, proximity of
the solids trap to drainage ways, flushing volumes and frequencies, and other
case -by -case circumstances which may affect the system management. Under no
circumstances will a solids trap be allowed to operate with a structural freeboard
equal to or less than a 25-year,.24-hour storm event. Solids traps are also
required to have a minimal dike wail or comparable best management practice
(BMP) in place to prevent outside surface water from entering the structure.
3.11 Trees on Embankments
Trees, shrubs, and other woody vegetation shall not be allowed to grow on the
lagoon/waste storage pond embankments. All trees shall be removed in
accordance with good engineering practices. Lagoon/waste storage pond areas
shall be accessible, and vegetation shall be kept mowed. Removal of trees does not
constitute a retrofit requiring a complete structural upgrade to current standards.
3.12 Proper Use of Lagoon (359) Standard
Current NRCS standards allow for design treatment volumes (i.e. Table 2.
Livestock Anaerobic Lagoon Criteria) that are lower than in previous standards for
farrow/wean, farrow/feeder, and boar/stud operations. However if this is done, the
current standards for sludge storage, excess water, etc. shall also be used to
properly utilize the standard. Attempting to use these new volumes on existing
operations that have been designed and approved under an earlier standard in
order to increase the number of animals will be considered an expansion and all
current criteria for expansion shall be met.

SUBJECT: Animal Waste Storage Pond Expansion
Hi -Rock Holsteins Farm, #29-20
Davidson County
Dear Mr. Palmer:
Several months ago, staff of the Division of Water Quality's Winston-Salem Regional
Office (DWQ-WSRO) performed a compliance inspection at your dairy farm in Davidson
County (see attached inspection report). While onsite, � staff observed that the existing waste
storage pond had been enlarged and a new embankment constructed on the west end of the waste
storage pond.
Saying that 2003 was an unusually wet year would be quite an understatement. Like you,
many operators were forced to alter their usual waste application practices. Other operators
removed animals from their facility or transferred the waste from one structure to another. As we
discussed during the compliance inspection,. you opted to expand your waste structure to contain
the excessive rainfall that entered the waste structure after accumulating on the concrete cattle
lot. Because of your efforts, the waste in the structure never reached a critical level, and thus, no
overflow or unpermitted discharge occurred.
However, the Guidance Document from the 1217 Group is very clear regarding how
such an expansion should be conducted (Part 3.2 on page 16 of the Seventh Guidance Document,
attached):
"If the facility is not being expanded but modifications to an existing lagoon are needed to
increase its storage or treatment volume, modifications can not be made without meeting current
standards or without updating the existing Certified Animal Waste Management Plan (CAWMP)."
And while the dam visually appeared to be structurally sound on the date of the inspection,
failure to follow the proper procedure prior to expanding a waste structure is a violation of
your CAWMP and cattle permit.
After discussions with several individuals in various agencies; it was determined that the
waste. structure still needs to be certified and incorporated into your current Certified Animal
Waste Management Plan (CAWMP). It is my understanding that you have already contacted a
professional engineer (PE) to certify the design and installation of the waste storage pond (see
highlighted sections on the attached Certification Form). I have also attached a copy of the
Interim NRCS Conservation Practice Standard for Waste storage Ponds to assist you in the
certification process. The following, minimum criteria, must be addressed by the engineer4',q,
order to evaluate certification:

1). Verify that the soils utilized in the expansion are adequate for compaction and
permeability (i.e. does the structure need a liner?).
2). Verify the slopes (total of 5:1, with neither slope being steeper that 2:I).
3). Observe the joint between the old and new construction to ensure that it is properly
contacted.
4.) Calculate and document the capacity of the structure.
5.) Determine the stability of the structure.
6.) . Have set -back requirements been met?
7.) Does the top width of the dam meet NRCS standards (minimum 10 feet)?
8.) Verify the cut-off trench.
9.) Estimate the amount of freshwater entering the waste structure.
10.) Determine the spillway capacity.
11.) Calculate the volumes for the 25 year/24 hour storm event and heavy rainfall factor.
Waste level markers will need to be re -set.
Our office will be contacting you again sometime in May 2004 to schedule your
compliance inspection for 2004. It is expected that by May you will have made significant
progress towards addressing the criteria listed above and that the expanded structure will soon be
incorporated into the CAWMP. If you have any questions concerning this correspondence or any
other animal waste management issues, please feel free to contact me at [phone].

Seventh Guidance Document —November 3, 2000
Committee
The foundation for this Guidance Document is the previous Guidance Documents
Technical
developed by the agencies represented on SB 1217 dated June 20, 1995, May 3,
Specialists
1996, August 9, 1996, January 2, 1997, May 21, 1997, August 18, 1997; and the
Sixth Guidance Memo, Revision One (January 8, 1998), Revision Two (August 25,
Guidance
1998), Revision Three (October 29, 1998), Revision Four (April 12, 1998), and
Document
Revision Five (January 12, 2000). The committee adopted these documents as the
Outside
foundation for this and future guidance documents. This document has been
Links
significantly reformatted and consolidated to enhance readability. Outdated items
were deleted or brought to current status.
This guidance is intended to address the common issues involved in implementing
the animal waste management rules and statutes. Additional guidance will be
provided as necessary to continue to clarify the issues contained in this
memorandum as well as new issues that may arise. The nature of the rules will
require judgment on the part of tech nical,specialists.
Guidance developed by the SB 1217 Interagency Group represent guidelines to
address questions from technical specialists and provides uniform interpretations
regarding requirements of animal waste management rules. However, for areas
where no standards exist, DWQ acknowledges these guidelines as acceptable
criteria to base a Certified Animal Waste Management Plan (CAWMP). Any
requested deviations from this guidance must be considered by DWQ on a case by
case basis to insure that the proposal provides equal or better protection. These
guidelines may also be incorporated by DWQ as permit conditions for an
operation's individual permit or general permit.

Lagoons/waste structures that are no longer in use shall be either managed to
Specialists
prevent discharge to surface and groundwaters; or decommissioned through a
closure plan. If a discharge does occur from an abandoned animal waste

management structure, the farm owner is subject to enforcement action by DWQ.
Document
In addition, If a water quality or groundwater problem is identified, DWQ will
Outside
require proper closure of the structure in addition to enforcement action and
Links
possible civil penalty.
For abandoned lagoons and waste structures, proper closure at the earliest
possible date is strongly encouraged. An unclosed lagoon is a potential safety and
environmental danger as well as a liability to the farmer. The closure plan outlining
the closure process shall follow NRCS Technical Standard 709. Proper closure
includes verification by a technical specialist that the work was done according to
standards and specifications, and the completed Animal Waste Storage Pond and
Lagoon Closure Report Form (Appendix 3.1) is submitted to DWQ within 15 days
following completion of the closure. The regional DWQ staff must be notified at
least 24 hours prior to the start of closure. Once the closure is completed and
acknowledged by DWQ, the structure is no longer considered part of the waste
management system, is deleted off of the state database, and may be used for
other purposes such as for irrigation or as a fishpond.
Either a closure plan or the management of an unused lagoon or waste structure
must be included in the CAWMP for facilities operating above threshold as specified
in 2W .0217.
Inactive lagoons or waste structures for deactivated facilities (operations with no
animals or operating below threshold) shall be properly managed to prevent
discharge to surface and groundwaters; however, the waste does not have to be
land applied by a certified animal waste applicator.
3.2 Renovation of Existing Animal Waste Management Systems With No
Expansion
If a facility is not being expanded but modifications to an existing lagoon are
needed to increase its storage or treatment volume, modifications can not be made
without meeting current standards or without updating,the existing CAWMP. Only
minor repairs can be made to the structure. Examples would be work to repair
minor erosion or the addition of more soil to the dike to provide greater stability
provided the top of the dike is not raised above the design elevation.
If a new lagoon or waste storage structure is added to an existing treatment
system (no increase in SSLW since February 1, 1993) to provide additional
treatment or storage and is tied into an existing structure (including connection by
pipe or lift station), the existing structure does not need to meet current design
tandards. While it is encouraged that all -existing structures be upgraded to meet
current standards any time there is construction on a site, it is not automatically
required. The technical specialist shall make a determination on the need for
structural upgrades during the evaluation of the overall system. If a determination
is made by the technical s ecialist th stru
the connection to the new structures and tha it is o
u ra es to meet current stan ards are r fired. In determining the stability of
the structure, the technics specia ist should evaluate and document signs of
previous discharges, pumping frequency (infrequent pumping suggest leaking),
slope stability, and seepage or wet areas along the backside of the dikes.
3.3 Lagoons in Wetlands or flood plains
Lagoons shall not be constructed in wetlands or a 100-year flood plain.

Senate Bill 1217 Interagency Group: Guida4ocument - Chapter 3
http://ti,",.sqou.edu/interagency/guidance/chapter3.htm#ch3q:
3.4 Design Standards
For a lagoon or waste storage structure constructed after February 1, 1993, the
design requirements are contained in the NCAC 2H. 0217 rules, state Statutes, and
NRCS and SWCC technical standards, in effect on the date of the design completion
as documented through NRCS design approval, a professional engineer (PE) seal,
or a CAWMP certification form. (Appendix 2.5A.) Only a PE or NRCS employee with
job approval authority may certify waste structures constructed after February 1,
1993. New construction and/or modification requires certification. Certified designs
for lagoons and waste storage structures in which construction has not commenced
within one year of a design standard change shall be constructed according to the
current design standards regardless of the original design date and require
recertification.
The SWCC has rescinded its animal waste management standards adopted May 2 .
1996 effective January 1, 2001. Certifications made after January 1, 2001 of farms
existing prior to May 2,.1996 must meet current NRCS standards.
3.5 NRCS Policy on ModiFcations
If NRCS provided technical assistance on the original waste structure, technical
assistance can be provided by NRCS. If NRCS did not provide technical assistance
on the original structure, then assistance generally will not be provided with the
modification because of the time required to adequately assess the design and
construction of the original structure.
3.6 Overflow Pipes Used for Emergency Spillways
Overflow pipe(s) in lagoons are acceptable as a lagoon emergency spillway,
provided they are properly designed for adequate capacity for the design storm
and have a stable inlet and outlet.
3.7 Liquid Levels for Staged Lagoons
In a staged lagoon system where the primary lagoon is gravity fed through a
transfer pipe into a secondary structure, the top of the transfer pipe shall be set
just below the primary lagoon's structural freeboard elevation if the primary
lagoon's 25-year, 24-hour storm requirement is calculated into the second
structure's temporary storage. Pipe size shall be designed to carry the 25-year
storm event without encroaching on the structural freeboard.
3.8 Pumping Markers for Staged Lagoons
Pumping markers are only required in those structures that do not gravity feed
through a free flowing (no valve) transfer pipe Into a subsequent structure, and in
those structures which serve as the primary source for land application. For
example, if waste empties from the house into a solids trap, is pumped to lagoon
2, gravity fed to lagoon 3, and then pumped to a solid set system for land
application, both the solids trap and lagoon 3 are required to have markers.
3.9 Requirements for Elevation Pumping Markers
NRCS standards require start and stop pumping markers. Since producers are
required to record freeboard and available storage capacity under an animal waste
general permit, it is highly recommended that they install elevation markers that
will clearly identify minimum and maximum liquid levels as well as a gauge that
enables accurate determination of the distance between the lowest point on the
embankment and the liquid level.
Waste storage structures are designed to be emptied completely and would not
require a minimum elevation marker. Anaerobic lagoons are designed with a
permanent treatment volume, and would require a minimum elevation marker so
the permanent treatment volume is maintained.

3.10 Freeboard for Solids Traps
Older swine operations had lagoons that were dug pits (no dike walls) and were
later converted into solids traps with waste pumped to a newer structure(s) to
satisfy retrofit requirements of the waste handling system. These structures are
allowed to operate with less than the one foot structural freeboard and 25-year,
24-hour storm event storage requirement if:
a back-up pump with power source is available in the event of equipment
failure to lift waste to a secondary structure,
a honey wagon/tanker is available with the capacity to empty the structure,
or
3. a secondary containment structure is available to store the waste.
For exemption from the one -foot structural freeboard requirement, consideration
must be also given to the location of the seasonal high water table, proximity of
the solids trap to drainage ways, flushing volumes and frequencies, and other
case -by -case circumstances which may affect the system management. Under no
circumstances will a solids trap be allowed to operate with a structural freeboard
equal to or less than a 25-year, 24-hour storm event. Solids traps are also
required to have a minimal dike wall or comparable best management practice
(BMP) in place to prevent outside surface water from entering the structure.
3.11 Trees on Embankments
Trees, shrubs, and other woody vegetation shall not be allowed to grow on the
lagoon/waste storage pond embankments. All trees shall be removed in
accordance with good engineering practices. Lagoon/waste storage pond areas
shall be accessible, and vegetation shall be kept mowed. Removal of trees does not
constitute a retrofit requiring a complete structural upgrade to current standards.
3.12 Proper Use of Lagoon (359) Standard
Current NRCS standards allow for design treatment volumes (i.e. Table 2.
Livestock Anaerobic Lagoon Criteria) that are lower than in previous standards for
farrow/wean, farrow/feeder, and boar/stud operations. However if this is done, the
current standards for sludge storage, excess water, etc. shall also be used to
properly utilize the standard. Attempting to use these new volumes on existing
operations that have been designed and approved under an earlier standard in
order to increase the number of animals will be considered an expansion and all
current criteria for expansion shall be met.

WASTE STORAGE POND
(number)
Code 425
DEFINITION
An impoundment made by excavaiion or earthfill
for temporary storage of animal or other
agricultural waste.
PURPOSE
To store liquid and solid waste, waste water, and
polluted runoff to reduce pollution and protect
the environment.
CONDITIONS WHERE PRACTICE
APPLIES
This practice applies where: (1) an overall waste
management system has been planned; (2)
temporary storage is needed for waste generated
by agricultural production or processing; (3)
soils are suitable for retaining the waste or can be
sealed; and (4) where livestock are concentrated.
This standard establishes the minimum
acceptable requirements for design, construction,
and operation of waste storage ponds. Under this
standard embankments are limited to an effective
height of 35 ft. or Iess and to hazard class (a).
This standard does not -apply to waste treatment
lagoons or to waste storage structures.
CRITERIA
Location
The waste storage pond shall not be located on a
flood plain unless it is protected from inundation
or damage by a flood event that occurs once
every 25 years.
Waste Storage Ponds shaII be located as close to
the source of.waste and as far from neighboring
dwellings or other areas of public use as
practical.
Nonpolluted runoff, from outside drainage areas,
should be excluded to the fullest extent possible.
Non -polluted runoff that can not be excluded
shall be included in the design capacity.
The minimum distance from wells and other
water sources must be in compliance with state
and local ordinances. It is the responsibility of
the designer to ensure that current State and local
distance requirements are met.
Conservation practice standards are reviewed periodically, and updated if needed. To obtain the current version
ofthis standard, contact the Natural Resources Conservation service.

Hazard Classification
The area downstream of the embankment must be
evaluated carefully to determine the impact from
a sudden breach of the proposed embankment on
both structural and environmental features. This
evaluation must consider all existing
improvements and those improvements that may
reasonably be expected to be made during the
useful life of the structure. The results of this
examination provides for the proper hazard
classification of the embankment. Only hazard
class (a) embankments are to be designed under
this standard. See Engineering Note keeping,
Field Office Technical Guide Standard 378 or
National Engineering Manual 520.21 for
guidance concerning documentation of hazard
class determination.
Emergency Action Plan
An Emergency Action Plan shall be prepared for
each waste storage pond. The plan will outline
steps to be followed in case of an emergency with
the storage pond such as overflow, breaching,
leakage, need for emergency land application,
etc. As a minimum it will contain the following
items for the owner/operator to carry out in the
event of an emergency:
Call the Division of Environmental
Management (DEM) to report the problem
Include name and phone number of the
appropriate regional office. If outside
normal business hours, call the NC
Emergency Management Office in Raleigh
and ask them to contact DEM. Give the
flame of the facility, location and DEM
registration/ certification number.
• Call 911 or the Sheriffs Department if there
is danger to downstream property
(residences, road, etc.). Include phone
.number.
425-3
• Contact Contractor(s) of owner's choice to
begin repair of problem to minimize off -site
damage. Include names and phone
number(s).
• Contact the technical specialist who certified
the waste storage pond. Include phone
number. If this specialist is no longer
working, contact one who has design
approval.
A copy of this plan containing current telephone
numbers must be available at each site. It should
be posted in a readily available location.
DESIGN CRITERIA
Site Investigation
A detailed site investigation shall be made for
each waste storage pond prior to design. This
investigation should include; but not be limited to
evaluations of, distance from residences and
other private or public use facility, proximity to
the 100-year floodplain, perennial streams as
shown on the USGS Quad Sheet, zoning
jurisdiction of municipalities, utilities in the
construction area, wetlands, available land for
disposal, soils, and other environmental factors,
etc.
If wetlands may be involved, contact the Corps
of Engineers and/or NRCS for a wetland
determination/delineation. If wetlands are
involved, a 401 water quality certification and a
404 permit may be needed.
During the site investigation or construction
phase, it must be verified that no subsurface tile
lines are present. On sites that are located on
cropland or land that has been cropped in the
past and is land with soil types that respond to
subsurface drainage, an observation trench along
the entire length of the embankment shall be

except when special management practices or
techniques permit otherwise. In no case shall a
plan be developed with less than 60 days of
storage capacity.
A means of clearly identifying the level of the
pool at maximum planned volume shall be
installed at each site. A,permanent marker shall
be placed in the pool area to clearly indicate the
maximum level of waste that can accumulate
before removal of effluent must be initiated.
With Outside Drainage Area
1. Manure and excess water'
2. Normal precipitation that falls on pond surface
less evaporation on pond surface for the time
which results in the greatest storage
requrements �.
3. Undiverted runoff from drainage area for
normal rainfall during storage period.
4. 25-year, 24-hour precipitation on pond surface.
5. Undiverted runoff from 25-year, 24-hour storm
from drainage area.
425-5
Design volume
Waste storage ponds shall store the design
volume plus an allowance for freeboard. Design
volume is the minimum volume required to store
waste for the planned storage period. It is the
total of the following table.
Without Outside Drainage Area
1. Manure and excess water.
2. Normal precipitation that falls on pond surface
less evaporation on pond surface the time of year
which results in greatest storage regiuirements'.
3. 25-year, 24-hour precipitation on pond surface.
Accumulated during the storage period.
Note: Additional temporary storage may be provided to meet management goals.
Domestic and industrial waste from washdown
facilities, showers, toilets, sinks, etc., shall not be
discharged into the animal waste manggnent
system.
Cutofr Trench
A cutoff of relatively impervious material shall
be provided under the embankment if necessary
for seepage control. The cutoff shall be located
at or upstream from the centerline of the dam. It .
shall extend up the abutments as required and be
deep enough to extend into a relatively
impervious layer or provide for a stable
embankment when combined with seepage
control. The cutoff trench Shall have a bottom
width adequate to accommodate the equipment
used for excavation, backrilI, and compaction

be determined by the designer. Access should be
provided to the pipe for nodding in case of
blockage.
Pipes and open inlets that convey waste to the
pond shall be designed and installed in a manner
that will prevent erosion of the pond side slope.
This will be accomplished by (I) extending the
pipe or inlet beyond the slope of the pond, (2)
installing an armoring surface such as rock
riprap or concrete on the slope, or (3) using a
flexible pipe that wiII conform to the surface of
the slope and safely convey the effluent into the
pond.
Pipes
If any pipes are to be placed through the
embankment, the location and method of
installation shall be approved by the designer of
the embankment or a technical specialist
designated by the Soil and Water Conservation
Commission to design and approve waste storage
ponds. The installation shall be certified by the
inspector.
Emergency Spillway
Waste storage ponds having a maximum design
liquid level of 3 feet or more above natural
ground shall be provided with an emergency
spillway to prevent overtopping. The crest of the
emergency spillway shall be located at the same
elevation as the top of the 25-year, 24-hour storm
storage. The emergency spillway shall be placed
in undisturbed soil when possible. When it must
be placed in fill material, precautions shall be
taken to insure the integrity of the structure.
The emergency spillway shall pass a 25-year, 24-
hour storm without overtopping the embankment.
There shall be a minimum of 1 foot of freeboard
above the designed depth of flow in the
emergency spillway. Where a waste storage
pond empties into another waste storage pond
and the liquid level is positively controlled by an
425-7
adequately sized overflow pipe, no emergency
spillway is required for the primary waste storage
pond.
Protection
If the pond will create a safety hazard, it shall be
fenced and warning signs posted to prevent
children and others from using it for purposes
other than intended:
A protective cover of vegetation will be
established on all disturbed areas. Temporary
vegetation may be used until permanent
vegetation can be established. Vegetation %kill be
established in compliance with Critical Area
Treatment standards (342-11) of the Technical
Guide.
The pond shall be fenced, if necessary, to protect
the vegetation.
Erosion and Sediment Control Measures
Plans for waste storage ponds shall include
temporary measures for the control of erosion
and sedimentation during the construction period.
Permanent vegetation will be established on all
disturbed areas.
CONSIDERATIONS
If the embankment is over I5 feet high and
impounds over I0-acre feet of effluent, a permit
must be obtained as required by the North
Carolina Dam Safety Law.
When siting the waste storage pond due
consideration should be given to access to other
facilities, ease of loading and unloading wastes,
the overall waste management plan, and health
and safety factors. The waste storage pond
should be located so that prevailing winds,
vegetative screening, and building arrangement
minimize odor and visual resource problems.

The Guidance Document from the 1217 Group is very clear (Part 3.2 on page 16 of the Seventh
Guidance Document).
"If the facility is not being expanded but modifications to an existing lagoon are needed to increase its
storage or treatment volume, modifications can not be made without meeting current standards or
without updating the existing CAWMP."
He should have also submitted a permit modification request.
Do we know how close the WSP comes to the current NRCS Standards for volume, liner, buffers, etc.?
Thanks

Dennis,
Sue's email (see bottom of page) is a pretty good summary of what's going on. Facility number is
29-20. He sent in an amended certification in 1999 and his permit was issued in 2000 for 310 dairy
cattle. The database still lists his operation at 120 cattle and needs to be updated.
Mike Palmer, facility operator/owner, saw that his WSP was getting full this winter and he couldn't
get a honey wagon on the fields ....... so ....... he just built the existing WSP larger. He's not expanding
cattle numbers. Per my discussions with Mr. Palmer and Lloyd Phillips (SWCD), while
SWCD/NRCS couldn't cost -share on this endeavor, they did tell Mr. Palmer what would need to be
done if the WSP were to meet NRCS standards. It's my understanding that SW only discussed slope
and seeding rate. According to SW, they didn't realize that the WSP expansion would need a new
certification and should meet current NRCS standards (set -back and liner). The original dam was
breached so waste is now being stored in the expanded portion.
In general, the operation and record keeping is ok. The operator can be difficult to work with but has
always done what I ask of him in the end. The expanded WSP dam actually looks pretty good in my
opinion. Just needs a final grading and seeding.
I think that Mr. Palmer needs to have a PE sign off on sections IIA and IIIA of the certification. My
question is: what standards would the PE be signing to?
A final note: Davidson SWCD has normally been very conscientious and helpful to me. Lloyd
typically calls me with any questions/answers before calling the farmer. Lloyd said that it just didn't
occur to him that an existing WSP would need to be re -certified if it was only being expanded to hold
more waste and not for an increase in cattle numbers.

I just spoke with Mr. Lloyd Phillips, Davidson SWCD per Melissa's
recommendation to him to call me.
Melissa, correct me if anything is wrong here, this is the situation as
described to me:
Dairy farmer decided on his own to enlarge his waste holding pond
This was done to increase the storage time, not herd size
Farmer did it all on his own, there is no design, or construction
approval.
NRCS would not have been able to assist him because there is a house 300
feet across the road.
The original structure was only certified for volume as grandfathered
in.
The expansion would have required the entire system to be brought up to
new NRCS standards and should have been designed by NRCS or PE.
What do we do now?
This seems more like a compliance issue than permitting. Yes he should
have gotten a permit first, but otherwise permitting wouldn't be
involved. I'm happy to assist in anyway I can. I think there needs to
be some discussions about what DWQ will do now, and what will be
required of the farmer. I told Mr. Phillips, SWCD that Melissa would
stay in touch with him and give him status updates when DWQ decided what
steps had to be taken.

Compliance Inspection
Pamolla Farms, #29-20
Davidson County
Dear Mr. Palmer:
The purpose of this letter is 'to summarize the findings of your compliance
inspection conducted August 24, 2000. Melissa Rosebrock of the Division -of Water
Quality -Winston-Salem Regional Office performed the inspection. Although the waste
handling system, other farm operations, and record keeping appeared in good condition,
our staff noted a discharge of liquids and solids from the lower', paved, barnlot that
warrants your immediate attention and action.
On the date of the inspection, Staff discovered past evidence of a dark-brown/gray
substance: approximately one to two foot in width, extending several hundred feet from
the concrete lot, along the corn field and into the field where the waste dispersed.
Although on the date of the inspection there was no discharge flowing, the current
situation allows for the potential discharge to surface waters of the State. Please be
advised that the non -permitted discharge of any type of wastewater to the waters of
the State is illegal as per North Carolina General Statute 143-215.1 and could
subject you to civil penalties of up to $25,000 per day per violation.
It is our understanding that you were first made aware of the current situation
H=�
during a May 30, 2000 inspection performed b Rock Durham with the Soil and Water
g Y p p Y Y
Conservation District (SWCD). Since that time, we also understand that you have
contacted the Davidson SWCD for assistance regarding the design and implementation of
a drop box and piping for conveyance of the runoff to the waste holding pond. We urge
your continued cooperation with the local Field Office in developing a solution.

Hi Melissa,
I finished up Davidson county this week. There were a few problems.
I guess the main one was on 29-20 Mike Palmer's. There was evidence of a
past discharge off his concrete lot. I spoke to the local SWCD and asked
them to see what they could do. I suggested placing some curbing with a
drop box and piping to the storage pond if the elevation would work out.
It is on the low side of the lot between the new freestall barn and the
old barn.
The Smiths had applied for corn ground in Sept. I had marked
evidence of a past discharge on G. Smith's last year from his expecting
cow barn, but couldn't see any this year. He keeps around thirty there
and scrapes into his box spreader.
You'll enjoy Larry Pope. He says he has not applied since Spring
'98. He claims he has more evaporation than waste produced even though
his plan says he produces 1.3 million gals. of waste with 52000 birds.
He said he hadn't had birds since March and I said well that may have
something to do with it. He said he wouldn't have had to apply even if
he had birds the whole time. He applies with a honey wagon.
I am planning on going to Guilford co. the weeks of the 12 and 19.
Talk to you later. Let me know when you want to get together to go over
the wettable acre form.
Alan is on vacation this week. See ya.

Animal Waste Management System
Facility Number 29-20
Davidson County
This letter is being sent to clarify the recordkeeping requirement for Plant Available Nitrogen (PAN)
application on fields that are part of your Certified Animal Waste Management Plan.
In order to show that the agronomic loading rates for the crops being grown are not being exceeded, you
must keep records of all sources of nitrogen that are being added to these sites. This would include nitrogen
from all types of animal waste as well as municipal and industrial sludges/residuals, and commercial fertilizers.
Beginning January 1, 2000, all nitrogen sources applied to land receiving animal waste are required to
be kept on the appropriate, recordkeeping forms (i.e. IRR1, IRR2, DRY1, DRY2, DRY3, SLURi, SLUR2,
SLD1, and SLD2) and maintained in the facility records for review. The Division of Water Quality (DWQ)
compliance inspectors and Division of Soil and Water operation reviewers will review all recordkeeping during
routine inspections. Facilities not documenting all sources of nitrogen application will be subject to an
appropriate enforcement action.
Please be advised that nothing in this letter should be taken as removing from you the responsibility or
liability for failure to comply with any State Rule, State Statute, Local County Ordinance, or permitting
requirement.
If you have any questions regarding this letter, please do not hesitate to contact Ms. Sonya Avant of the
DWQ staff at [phone] ext. 571.
