I have read and understand the Required Specifications concerning animal waste management that are included with this plan. Signature Signature (manager or S i� Date g /G 12 Date This plan meets the minimum standards and specifications of the U.S.Department of Agriculture - Natural Resources Conservation Service or the standard of practices adopted by the Soil and Water Conservation Commission. Plan Approved By: L 2i — Technical Specialist Signature 8/15/2024 Date Stamey Closure 8/14/2024 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. 8/15/2024 10:38:01 AM 1 / 1 Waste Storage Closure Source Description Stamey Closure SOURCE: Stamey Farm SlurryStore Closure Date Measured: 05/24/2024 Lagoon Dimensions: TOP - 55 X 55; BOTTOM - 55 X 55; SIDE SLOPES - 1:1 Liquid Depth: 20.00 ft.; Liquid Volume: 375,000 gallons.

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.

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).

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. USDA is an equal opportunity provider, employer, and lender. 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.

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.
