Type of Plan: Nutrient Management with Closure Cleanout Only
Narrative:
This nutrient management plan is to address the closure of the waste storage pond and slurrystore
at Stamey Farm as part of the COVID Swine and Dairy Assistance Program.
All waste from the waste storage pond and slurrystore will be irrigated or broadcast land applied
onto crops in fields included in the closure plan. The closure plan includes both wheat or cover
crop and corn or soybeans in several fields to give flexibility in the timing of closure. Regardless of
timing or crop chosen to land apply the waste on, there is significant amount of land available to
complete the closure. Some land application of the waste may occur using the existing irrigation
reel and pulls located within fields 13, 5A, 5B and 7. If this occurs the acreages associated with
each pull and PAN applied to each pull should be deducted from the associated parent field
acreage and PAN balance.
Due to the low nutrient values in the wastewater, the application rates in the closure plan have been
reduced to approximately two acre inches. No more than one inch of wastewater should be applied
per day to allow for infiltration.
Once all waste is removed from both storage structures and verified, the dam on the waste storage
pond will be breach in the southwest corner and graded so it no longer impounds water. All
disturbed areas will be seeded and mulched to prohibit erosion. All waste transfer components
leading to the waste structures will be cut and capped, so they are unable to convey waste.
Prior to starting the closure process, DWR shall be given at least a 24 hour notice of starting.

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

Soil Metal Indices
Stamey Closure
Lagoon sludge often contains high concentrations of zinc and copper. High levels of these metals in soils can adversely affect plant growth. The following table
provides a conservative(maximum potential) estimate for increase in soil index values.* Due to inherit variability of waste and soil sampling, it is recommended
that conservative soil target levels be set for copper (e.g. Cu-1 < 700-1000) and zinc (e.g. Zn=1 < 300 for land where peanuts may be grown; for other cropland
Zn-I < 700-1000). Alternative application sites should be selected if the following table indicates that concentrations of these metals may approach excessive
levels. For maximum copper and zinc soil index limits, see the NRCS Nutrient Management Standard (Code 590).

Note: All of runoff will be designed to be stored in waste
storage pond. The slurry store will actually store a
significant amount of normal runoff unless lot runoff is
diverted away from pump pit. The storage period will be
somewhat greater than designed.

C. Sizing Waste Storage Pond
Bottom Dimensions
Waste Storage Pond
Top of Dam Area = 19,403 sq ft
Bottom Area = 4,900 sq ft
Area at 8.2' elev. above bottom = 14,921 sq ft
Area at 4.1' elev. above bottom = 9,910.5
Volume below 8.2 elev. above bottom
Volume = 8.2/6[4900 + 14,921 + 4(9,910.5)]
��. = 81,266 cu ft
Normal Pump Out Volume =
5„. 34,070 cu ft + 16,815 cu ft + .8 X 19,403 sq ft
= 66,407 cu ft per 6 months�� Y
= 132,815 cu ft per year
993,000 gal per year.
= 36.6 ac-in per year
Maximum pond level
0.51 + 1.5' + 21,997 cu ft/(14,921 sq ft)
l = 3.5' below top of dam
D. Pump out elevation and ESW elevation
The waste storage pond should be emptied before the
water level reaches the 25 yr - 24 hr storage volume. This
elevation is 3.5 ft below the top of dam elevation of the
pond. The emergency spillway elevation is planned 1.5 foot
below the top of dam elevation.
IV. Slurry Store
--� Manure and milking parlor wash water for milk herd will
be stored in a slurry store. Volumes of storage and storage
period will be calculated for the existing structure.
Existing dimensions are 23, high and 62' diameter.
1. Waste Volume
130 Milk Cows are on lot approximately 60k of the time.
35 Milk Cows are on one corner of lot.approximately 60k
of the time (i.e., this is a buy and sale group that numbers
and time on lot varies significantly).
An average of 25 dry cows are fed on lot once a day for
approximately 101i of the time
Volume = 13,0 cows * 14 gal-/day/cow * 120 days * 60%
7.48 gal/cu ft
= 17,519 cu ft
o ume = 35 cows * 14 _gal/day_/cow * 120 days * 60;
7.48 gal/cu ft
= 4,717 cu ft
Volume = 25 dry cows * 14 galLday_cow'* 120 days * 1016
Jr C,,,e 7.48 gal/cu ft
561 cu ft
Total Waste = 17,519 cu ft + 4,717 + 561 = 22,797 cu ft
2. Milking Parlor Wash Water
Parlor is a flat 16 with 8 milking machines
i. Pipeline and milker wash water 200 gal./day
ii. Tank wash water 250 gal./day
iii. Milk house floor wash water 500 gal./day
iv. Cow wash water 50 gal./day
900 gal./.day
Volume = 900 gal/day*1 cu ft/7.48 gal* 120 days
= 14,438 cu ft
3. Lot Runoff
Lot runoff passes through the pump basin. A percentage
of lot runoff remains in the basin each rainfall event.
Depending on how full the basin is with manure will affect
the volume of lot runoff pumped.to the slurry store. It is
estimated that 50k of the normal lot runoff will be stored
in the slurry store.
` y Volume = 0.50 X (30,650 + 7,875) 19,262 cu ft per 180 days
�11 = 12,842 cu ft per 120 days
-,� 4. Rainfall minus evaporation on surface
14.3 - 6.7 = 7.6" = 0.7 ft per 4 month
5. 25 yr - 24 hr rainfall on surface
Rainfall = 5.5" _ .5 ft
6. Freeboard = 6" _ .5"
7. Solids in bottom of tank not removed
1' cannot be removed in bottom
8. Checking Size of Tank
Design Volume = 22,797 cu ft + 14,438 cu ft + 12,842
= 50,077 cu ft
Design Depths = .7' + .5' + .5' + 1.0' = 2.7'
Available storage Depth = 23' - 2.7' = 20.3'
Available storage Volume = Tank area X 20.3'
= 3,019 sq ft X 20.3'
= 61,286 cu ft OK
i Normal Pump Volume =
22,797 + 14,438 + 12,842 + .7' X 3,019 sq ft
= 52,190 cu ft/120 days
= 158,744 cu ft per year
= 43.7 ac-in per year
= 1,187,000 gal/year
25 yr 24 hr maximum storage level =

Natural Resources Conservation Service
CONSERVATION PRACTICE STANDARD
WASTE FACILITY CLOSURE
CODE 360
(no)
DEFINITION
The decommissioning of a facility where agricultural waste has been treated or stored, and is no longer
used for the intended purpose.
PURPOSE
The practice is implemented to —
Protect the quality of surface water and groundwater resources
• Mitigate air emissions.
• Eliminate a safety hazard for humans and livestock.
• Safeguard the public health.
CONDITIONS WHERE PRACTICE APPLIES
This practice applies to an agricultural waste facility or livestock production site that is no longer needed
as a part of a waste management system and is to be permanently closed or converted for another use.
These facilities include liquid/dry waste storage or treatment facilities, confined animal housing, feedlots,
livestock yards, and animal mortality or composting facilities.
This practice applies where impoundments that are to be converted to fresh water storage meet the
current NRCS conservation practice standard to which the impoundment is proposed to be converted.
This practice applies to rehabilitation of soil contaminated by agricultural wastes that have been stored or
treated onsite.
This Practice does not apply to an agricultural waste facility that will be expanded or rehabilitated. Use
NRCS Conservation Practice Standards (CPSs) Waste Storage Facility (Code 313) or Waste Treatment
Lagoon (Code 359), respectively, for rehabilitated or expansion of an existing waste storage facility or
treatment lagoon.
This practice does not apply to the demolition of components such as confined animal housing,
feedbunks, or fencing. Use NRCS CPS Obstruction Removal (Code 500) for structures not directly
transferring or controlling manure to waste facility.
This Practice does not apply to sites contaminated by materials that require the issuance of a hazardous
waste permit, such as fuel or pesticides.
NRCS reviews and periodically updates conservation practice standards. To obtain the current NRCS, NC
version of this standard, contact your Natural Resources Conservation Service State office or October 2023
visit the Field Office Technical Guide online by going to the NRCS website at
https://www.nres.usda.gov/ and type FOTG in the search field.

360-CPS-2
CRITERIA
General Criteria Applicable to All Purposes
All Federal, State, and local laws, rules, and regulations, including National Pollutant Discharge
Elimination System (NPDES) requirements, shall be adhered to during the closure of a waste facility.
Waste transfer components that convey waste materials to a treatment or storage facility and facility
components that provide drainage from the waste facility shall be removed. Replace transfer components
with compacted earth material or otherwise render transfer components unable to convey waste.
To the maximum extent practicable, remove all agricultural waste and associated materialsthat could
negatively affect water or air quality, or pose a safety hazard. Utilize all liquid, slurry, sludge and solid
waste, and soil removed from the facility in accordance with NRCS CPS Nutrient Management (Code
590).
Use precautions (fencing and warning signs) where necessary to ensure that the facility is not used for
purposes incompatible with the facility modification.
Erosion and pollution control
For facilities that receive surface runoff flows including flows generated within the facility footprint, soils
and hydrology analysis shall be completed to quantify expected runoff and plan/design appropriate water,
erosion, and grade stabilization controls.
Revegetate or treat all disturbed areas with other suitable measures used to control erosion and restore
the aesthetic value of the site. Treat areas not suitable for revegetation through normal cropping practices
in accordance with applicable NRCS erosion, grade, and water control CPSs including but not limited to
Grade Stabilization Structure (Code 410), Grassed Waterway (Code 412), Diversions (Code 362),
Mulching (Code 484), and Critical Area Planting (Code 342).
Liquid and slurry waste removal
Agitate and pump all liquid and slurry wastes to the maximum extent practicable. Add water as necessary
to facilitate the agitation and pumping. Utilize the wastewater in accordance with NRCS CPS Nutrient
Management (Code 590).
If the bottom of the lagoon or structure at the actual time of closure will support earth -moving equipment, it
must be scraped. Soil stability for earth -moving equipment shall be determined and documented at the
actual time of closure by an NRCS qualified Engineer, or an NRCS qualified Technician, or a state
qualified technical specialist. For lagoons or structures that are not to be scraped due to documentation
that the bottoms will not support earth -moving equipment as determined at the actual time of closure, the
depth of "agitated" waste material remaining in the lagoon or structure at the actual time of closure may
not exceed a maximum depth of one (1) foot. An NRCS qualified Engineer, or an NRCS qualified
Technician, or a state qualified technical specialist shall verify and certify the sludge has been
satisfactorily removed."
Sludge removal
During sludge removal operations, the integrity of the liner shall be maintained, if one is present. Remove
sludge to the maximum extent practicable and utilize in accordance with NRCS CPS Nutrient
Management (Code 590).
Impoundment closure
Three options are associated with the decommissioning of liquid waste impoundments. Use one of the
following options.
Breach embankment impoundments
Embankment impoundments (those with a depth of water at the design water level of 3 feet or more above
natural ground) may be breached so that they no longer impound water. Liquid sludge waste shall be
removed from the impoundment before breaching the embankment. Grade the embankment material into
NRCS, NC
October 2023
360-CPS-3
the impoundment area, and vegetate the area for another use or retain the embankment if the
impoundment area surface has been sufficiently cleaned so that runoff leaving the site would not be
considered contaminated by the wastes. Remove concrete, pipe appurtenances, and flexible membrane
liners or render the membrane liner unable to impound water. Properly dispose of removed concrete,
pipe, and membrane liner materials. Design stable side slopes and bottom of the breach for the soil
material involved. Three horizontal to one vertical (3:1) is the steepest side slope allowed for a finished
breach slope.
Backfill excavated impoundments
Excavated impoundments may be backfilled so that the area is unable to impound water and may be
reclaimed for other uses. Liquid and sludge waste shall be removed from the impoundment prior to
backfilling. Remove and properly dispose of concrete, pipes,flexible membrane liners, and any other
structures or materials associated with the impoundment. Backfill the excavated area to a design height a
minimum of five percent above the finished grade to allow for settlement. Construct the top 1 foot of the
backfill using the most impervious soil material readily available and mound the fill to shed precipitation
runoff without causing erosion. Incorporate available topsoil where feasible to aid the establishment of
vegetation.
Conversion to fresh water storage
Converted impoundments shall meet the requirements as set forth in the appropriate NRCS CPS (e.g.
Pond (Code 378)) for the intended water storage purpose. Use the National Engineering Manual (NEM),
Section 501.23 for the investigation of structural integrity if the original impoundment was not constructed
according to NRCS standards. Liquid and sludge waste shall be removed from the impoundment prior to
conversion. When it is not practical to remove the sludge from a waste impoundment that is being
converted to fresh water storage, the impoundment must not be used for fish production, swimming, or
livestock watering until the water quality is adequate for these purposes.
Alternate Method of Closure
There are existing lagoons/structures that may be closed by the following alternate method.
This alternative closure process consists of vacuum dredging the sludge and leaving the liquid.
Lagoons/Structures which have a liquid waste analysis of more than 40 parts per million of total N before
sludge removal cannot be closed by this alternate method.
Locations on the lagoon/structure bottom where sludge is 0.2 foot or greater must be dredged. Where the
sludge is less than 0.2 foot in depth, dredging is not required.
Sludge must be removed to the maximum extent practicable on the slopes, but in no case shall there be
more than 0.2 ft. of sludge in the bottom when finished.
The lagoon/structure must be converted to fresh water storage. Spillways, if required under this standard,
must meet the requirements of the Pond Conservation Practice Standard (Code 378) and have adequate
soils and hydrology analysis to properly design structure appurtenances including but not limited to
principal and auxiliary spillways.
Required documentation for the above criteria includes:
A liquid waste analysis performed by the North Carolina Department of Agriculture & Consumer Services
(NCDA&CS) or other accredited lab. The sample shall be taken by Division of Soil and Water
Conservation (DSWC) staff, Division of Water Resources (DWR) staff, or NRCS staff with a WUP/NM
designation as a technical specialist.
A survey of the lagoon/structure showing the bottom elevation and depth of sludge before and after
dredging using a "sludge judge" or other measuring device made for this purpose, on a 25 foot grid, or
NRCS, NC
October 2023
360-CPS-4
closer, if needed to show true size and volume of sludge. The survey and volume computations shall be
signed by a technical specialist with the SD or SI designation.
A representative from Division of Water Resources(DWR), Division of Soil and Water Conservation
(DSWC), or an NRCS qualified Engineer, or an NRCS qualified Technician must verify that the sludge has
been satisfactorily removed.
Fabricated liquid waste facilities
Fabricated liquid waste facilities must be demolished, disassembled, or otherwise altered so they no
longer impound water. Temporarily store disassembled materials such as pieces of metal, concrete, etc.,
in such a manner that they do not pose a hazard to animals or humans.
Bury demolished materials onsite or move material offsite to locations designated by State or local
officials. If buried onsite, cover the materials with soil to a settled depth of at least 2 feet. Backfill finished
grade must exceed the finished design height by a minimum of five percent to allow for settlement.
Mound the backfill sufficiently to divert runoff from the site after the backfill settles.
Dry waste storage or treatment facilities
Remove walls and other structural members or otherwise render the site unsuitable for stacking or treating
waste.
Determine the depth of soil remediation by evaluating the soil at dry waste facilities such as confined
animal housing, feedlots, livestock yards, or composting facilities with earthen floors.
Include laboratory analyses of the soil profile in the evaluation for any nutrients needed to determine the
required depth of rehabilitation. Take soil samples at multiple locations and depths within the facility. Take
one sample per depth interval per acre, of the area being decommissioned with a minimum of three
samples per depth interval. Samples taken for each specified sampling depth interval may be
consolidated into a single set (e.g., three samples taken at the 0-to 6-inch-depth interval may be
consolidated into a single sample for testing). Collect, prepare, and test soil samples in accordance with
NRCS CPS Nutrient Management (Code 590).
Use the results of the soil analysis to prepare a plan to recover the site for its intended use. Utilize the
following site appropriate options, if needed:
• Adjust pH to restore desired crop growing conditions.
• Plant salt -tolerant plants to restore the site to desired crop conditions. Monitor the harvested
vegetation for nitrogen, phosphorus, and potassium removal.
• Select plants and erosion control practices to minimize phosphorus transport from the site and
facilitate remediation of excessively high phosphorus levels.
Although in -situ processes are the preferred method for adjusting the soil conditions, removal of a portion
of the soil may be necessary. Land apply the removed soils in accordance with NRCS CPS Nutrient
Management (Code 590). Grade or backfill the excavated areas to shed rainfall and prevent ponding of
runoff. Where feasible, use available topsoil to aid in the establishment of permanent vegetation.
CONSIDERATIONS
Where practical, conduct preclosure soil and water (surface and subsurface) testing to establish baseline
data surrounding the site at the time of closure. Establishing baseline data can be used in the future to
address soil and water issues.
Where a dense mat of floating vegetation covers the surface, reduce pumping effort to empty waste
impoundments by first applying herbicide to the vegetation and then burning the residue. Obtain
appropriate permits before burning. When conducting burning, take necessary actions to ensure that
smoke is managed to minimize impacts to downwind populations.
NRCS, NC
October 2023
360-CPS-5
Alternative methods of sludge removal may be required where the impoundments contain large amounts
of bedding, oyster shells, soil, or other debris.
Minimize the impact of odors associated with land -applying dry wastes or with agitation, emptying, and
land -applying wastewater and sludge from a waste impoundment by conducting these operations at a
time when the humidity is low, when winds are calm, and when wind direction is away from populated
areas. Adding chemical and biological additives to the waste prior to agitation and emptying can reduce
odors. Odor impacts from land application can also be mitigated by using an incorporation application
method.
Minimize agitation of the wastes to only the amount needed for pumping to reduce the potential for
release of air emissions.
Soil used to fill excavated areas should not come from important farmlands such as prime, statewide,
local, or unique farmlands.
If testing of soil around the facility indicates a need for remediation, use an appropriate NRCS CPS for
planning and implementation.
A breached embankment may detract from the overall aesthetics of the operation. Remove the
embankment and return the site to its original grade.
Disassembled fabricated structures may be suitable for assembly at another site. Take care during
closure to minimize damage to the pieces of the facility, particularly coatings that prevent corrosion of
metal pieces.
Take measures during closure activities to minimize site erosion and pollution of downstream water
resources. This may include such items as silt fences, haybale barriers, temporary vegetation, and
mulching.
To minimize potential impacts to livestock, such as nitrate poisoning, initiate a testing and monitoring
program of nutrient levels in crop products, particularly livestock feeds, harvested from sites of closed
animal confinement facilities.
Consider revegetating using species or diverse mixes that are native or adapted to the site and have
multiple benefits. Native species may be used when appropriate for the site. To benefit pollinators and
other wildlife, flowering shrubs and wildflowers with resilient root systems and good soil -holding capacity
also should be considered for incorporation as a small percentage of a larger grass -dominated planting.
Where appropriate consider a diverse mixture of forbs to support pollinator habitat.
PLANS AND SPECIFICATIONS
Prepare plans and specifications that describe the requirements for applying the practice to achieve its
intended use. As a minimum, include—
• A plan map showing the location and extent of the practice.
• NRCS Job Classification for each planned conservation practice and an overall project job
classification
• A plan view of the layout of the waste facility's existing grade and final design grade including
topographic elevations and locations of survey benchmarks.
• Typical profiles and cross sections of the site as needed. These shall include original and planned
grades.
• Structural drawings including pipes and grade stabilization structures, details, and notes adequate
to describe the construction requirements.
• Requirements for erosion, grade, and water control measures and structures as needed. This may
include details for (but not limited to) Grade Stabilization Structures (Code 410), Grassed
NRCS, NC

• Odor management or mitigation requirement.
• Safety plan requirements. Note: Per Occupational Safety and Health Administration (OSHA)
confined space entry protocol, there will be NO entry of personnel into the confined space of an
enclosed waste facility without breathing apparatus or taking other appropriate measures.
OPERATION AND MAINTENANCE
Develop an operation and maintenance plan that is consistent with the purposes of the practice, its
intended life, safety requirements, and the criteria for its design.
The proper decommissioning of a waste facility and rehabilitation of any contaminated soil a waste facility
requires little or no operation and maintenance.
For the conversion of a waste facility to any other use, such as a fresh water facility, the operation and
maintenance will be in accordance with the appropriate NRCS CPS for the intended facility conversion
purpose.
