Realistic Yield estimates and Plant Available Nitrogen (PAN) recommendations are also provided for each crop as well as the crop's P205 Removal Rate. The Leaching Index (LI) and the Phosphorous Loss Assessment Tool (PLAT) Rating are also provided for each field, where available. If a filed's PLAT Rating is High, any planned manure application is limited to the phosphorous removal rate of the harvested plant biomass for the crop rotation or multiple years in the crop sequence. Fields with a Very High PLAT Rating should receive no additional applications of manure. Regardless of the PLAT rating starter fertilizers may be recommended in accordance with North Carolina State University guidelines or recommendations. The quantity of P205 applied to each crop is shown in the following table if the field's PLAT rating is High or Very High.

This farm has an existing dairy waste holding pond that will be closed and turned into a freshwater pond. Liquid waste will be applied, and then the receiving crop will be planted within 30 days of application. The crop fields to receive the waste will be planted into sorghum-sudan cover crop. The sorghum will remain on the fields as a cover crop and only receive 30 units of nitrogen per acre. If it is necessary to add more than 30 units of nitrogen per acre to any crop fields to close the liquid waste holding pond, those fields will be cut for hay. All liquid will be broadcast by honey wagon on fields listed within the Nutrient Management Plan. Once the liquids become more solid, front end loaders will push solids to one location of the waste holding pond in order for agi-pump to pump remaining solids into a honeywagon for application to crop fields. Any remaining solids will be applied to field I Tract # 100, incorporated/disced into the soil within 4 weeks of application, and planted with sorghum-sudan. 3/9/2023 10:48:43 AM 1 / 1 M LL H 3 as ■2 Q. � O V E m ^ LL O Ci > Q 0 0 O C Y y M M M M M Cl) Co Co Q O V O aQcQ O r r r r r (n r r r N 'C (D (D (D (D (D (D (D CO Q, Q 0 M 0 M 0 Cl) 0 M 0 CO 0 N 0 M 0 M 0 M QO J Q tm �G_f Q C Q CL y Z O CD C)O CD C)M (O C)m d n.�° Z -� Q (D (D (D (D (D M CD (D Z d N N N N N O N N a m N 2 @—N O-) O N C !U� !Ua� Uq v 0 � U U o U o U a "J t3 � oa =N @ O @ O @ O O O O O' Q M O O @ O Q Co Co Co m o 3°CI- m m m` c O- M (" M L� M M Lo M LO M (n Co M L M Qa MM COM COM CoM MM MM CoM MM MM fn N C (N C U)N C C N C W C to C U)C C �- � F F I r r r r r r v 'I r r V �t tt M V C C C C C C C C C a s a � anvn n n n n n U) no E E E E E E E E E R)>, m T O)>, 2) T P� 2 T R)>, 2'>, m 0@ 0@ O@ O@ 0@ 0@ O@ 0@ 0@ (U) S (n S (n a:(n 2 (n S U)2 U)I:(n S U) 2 tm J J J J f�6 J J J J N a y fq L Cl) �.

Fields that receive manure must have a soil analysis conducted at least once every three years. High levels of zinc and copper can adversely affect plant growth. Alternative crop sites must be used when the concentration of these metals approach excessive levels. Site life can be estimated by dividing the amount of copper and zinc to be applied in Ibs/acre by 0.036 and 0.071, respectively and multiplying the result by 0.85. By adding this quantity to the current soil index for copper or zinc, we can predict life of the site for waste disposal. In addition to copper and zinc indices, this table also provides a summary of lime recommendations for each crop based on the first crop listed on the most recent soil sample. Application of lime at recommended rates is necessary to maintain soil pH in the optimum range for crop production. If the first crop or rotation changes, these recommendations may need to be reevaluated to ensure optimal ranges ofr crop production are maintained.

Animal waste shall not reach surface waters of the state by runoff, drift, manmade conveyances, direct application, or direct discharge during operation or land application. Any discharge of waste that reaches surface water is prohibited. 2. There must be documentation in the design folder that the producer either owns or has an agreement for use of adequate land on which to properly apply the waste. If the producer does not own adequate land to properly dispose of the waste, he/she shall provide evidence of an agreement with a landowner, who is within a reasonable proximity, allowing him/her the use of the land for waste application. It is the responsibility of the owner of the waste production facility to secure an update of the Nutrient Management Plan when there is a change in the operation, increase in the number of animals, method of application, receiving crop type, or available land. 3. Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic crop yields based upon soil type, available moisture, storical data, climatic conditions, and level of management, unless there are regulations that restrict the rate of applications for other nutrients. 4. Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste may be applied to land eroding at more than 5 tons per acre per year but less than 10 tons per acre per year provided grass filter strips are installed where runoff leaves the field (see USDA, NRCS Field Office Technical Guide Standard 393 - Filter Strips). s. Odors can be reduced by injecting the waste or by disking after waste application. Waste should not be applied when there is danger of drift from the land application field. 6. When animal waste is to be applied on acres subject to flooding, waste will be soil incorporated on conventionally tilled cropland. When waste is applied to conservation tilled crops or grassland, the waste may be broadcast provided the application does not occur during a season prone to flooding (see "Weather and Climate in North Carolina" for guidance). 7. Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that runoff does not occur offsite or to surface waters and in a method which does not cause drift from the site during application. No ponding should occur in order to control odor and flies. s. Animal waste shall not be applied to saturated soils, during rainfall events, or when the soil surface is frozen. 9. Animal waste shall be applied on actively growing crops in such a manner that the crop is not covered with waste to a depth that would inhibit growth. The potential for salt damage from animal waste should also be considered. io. Nutrients from waste shall not be applied in fall or winter for spring planted crops on soils with a high potential for leaching. Waste/nutrient loading rates on these soils should be held to a minimum and a suitable winter cover crop planted to take up released nutrients. Waste shall not be applied more than 30 days prior to planting of the crop or forages breaking dormancy. 11. Any new swine facility sited on or after October 1, 1995 shall comply with the following: The outer perimeter of the land area onto which waste is applied from a lagoon that is a component of a swine farm shall be at least 50 feet from any residential property boundary and canal. Animal waste, other than swine waste from facilities sited on or after October 1, 1995, shall not be applied closer than 25 feet to perennial waters. 12. Animal waste shall not be applied closer than 100 feet -v a Well, 13. Animal waste shall not be applied closer than 200 feet of dwellings other than those owned by the landowner. 14. Waste shall be applied in a manner not to reach other property and public right-of-ways. 15. Animal waste shall not be discharged into surface waters, drainage ways, or wetlands by a discharge or by over -spraying. Animal waste may be applied to prior converted cropland provided the fields have been approved as a land application site by a "technical specialist". Animal waste shall not be applied on grassed waterways that discharge directly into water courses, and on other grassed waterways, waste shall be applied at agronomic rates in a manner that causes no runoff or drift from the site. 16. Domestic and industrial waste from wash down facilities, showers, toilets, sinks, etc., shall not be discharged into the animal waste management system. 17. A protective cover of appropriate vegetation will be established on all disturbed areas (lagoon embankments, berms, pipe runs, etc.). Areas shall be fenced, as necessary, to protect the vegetation. Vegetation such as trees, shrubs, and other woody species, etc., are limited to areas where considered appropriate. Lagoon areas should be kept mowed and accessible. Berms and structures should be inspected regularly for evidence of erosion, leakage, or discharge. 18. If animal production at the facility is to be suspended or terminated, the owner is responsible for obtaining and implementing a "closure plan" which will eliminate the possibility of an illegal discharge, pollution, and erosion. 19. Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular basis to prevent breakdowns, leaks, and spills. A regular maintenance checklist should be kept on site. 2o. Animal waste can be used in a rotation that includes vegetables and other crops for direct human consumption. However, if animal waste is used on crops for direct human consumption, it should only be applied pre -plant with no further applications of animal waste during the crop season. 21. Highly visible markers shall be installed to mark the top and bottom elevations of the temporary storage (pumping volume) of all waste treatment lagoons. Pumping shall be managed to maintain the liquid level between the markers. A marker will be required to mark the maximum storage volume for waste storage ponds. 22. Waste shall be tested within 60 days of utilization and soil shall be tested at least annually at crop sites where waste products are applied. Nitrogen shall be the rate -determining nutrient, unless other restrictions require waste to be applied based on other nutrients, resulting in a lower application rate than a nitrogen based rate. Zinc and copper levels in the soils shall be monitored and alternative crop sites shall be used when these metals approach excessive levels. pH shall be adjusted and maintained for optimum crop production. Soil and waste analysis records shall be kept for a minimum of five years. Poultry dry waste application records shall be maintained for a minimum of three years. Waste application records for all other waste shall be maintained for five (5) years. 23. Dead animals will be disposed of in a manner that meets North Carolina regulations. Uo 4MRCS United States Department of Agriculture Natural Resources Conservation Service NUTRIENT MANAGEMENT PLAN SUPPLEMENTAL INFORMATION N.C. Practice Job Sheet: NC-590 Prepared for: MAPL9 WE W F41-t"+-/ 1AA10A b rav0- rurrn By: Ken n H -RoaH Farm: Tracts ): z-oD Date:_L_JZo / ZOZ 3 WHAT IS NUTRIENT MANAGEMENT? Nutrient Management is applying nutrients from all sources with the right placement, in the right amount, at the right time, and from the right source to minimize nutrient losses to surface and groundwater. This practice is accomplished through development and implementation of a Nutrient Management Plan, which can be part of a broader Conservation Plan or CNMP that addresses multiple resource concerns. PURPOSE OF NUTRIENT MANAGEMENT A nutrient management plan is intended to accomplish one or more of the following objectives: • To budget, supply, and conserve nutrients for plant production. • To minimize agricultural nonpoint source pollution of surface and groundwater resources. • To properly utilize manure or organic by- products as a plant nutrient source. • To protect air quality by reducing odors, nitrogen emissions (ammonia, oxides of nitrogen), and the formation of atmospheric particulates. • To maintain or improve the physical, chemical, and biological condition of soil. CONTENTS OF THE NUTRIENT MANAGEMENT PLAN The following components are included in nutrient management plan specifications typical of more 'traditional' fertilizer and manure application methods. When precision ag/variable rate application technology is utilized, see the next section of this Job Sheet for additional guidance on plan requirements. • aerial site photograph(s)/imagery or site map(s), and a soil survey map of the site, • Sufficient soils information —such as dominant soil map until for each planned field —needed to apply nutrients at RYE and Soil Test Report determined rates as appropriate; and to not exceed rates determined by nutrient risk assessment planning criteria. • location of designated sensitive areas and the associated nutrient application restrictions and setbacks, • results of approved risk assessment tools for any necessary evaluations for nitrogen, phosphorus, and erosion losses. • current and/or planned plant production sequence or rotation, • soil, water, compost, manure, organic by- product, and plant tissue sample analyses applicable to the plan. Where non-NCDA soil testing labs are used, nutrient recommendations must be made using NCDA- similar guidelines and methodologies. Note: high levels of soil copper and zinc may be toxic to production crops.

This Job Sheet is a required supplement to the Nutrient Management Plan. NC Permitted Animal Operations: For NC DENR-DWR or NPDES permitted animal operations, the waste utilization portion of the Certified Animal Waste Management Plan (CAWMP) must meet requirements specified by the Permit. The NC 1217 Interagency Group provides guidance on the required minimum elements of a CAWMP. This guidance is found in Sec 1.1 of the latest 1217 Guidance Document, located at: http:Hwww. ncagr.gov/SWC/tech/guidancedocumen ts.html. Nitrogen Leaching Index Values Nitrogen Leaching Index values, obtained through use of current Soil Hydrologic Group (SHG)-based LI index maps in Sec II of the NC FOTG or RUSLE 2_field-specific soil loss calculations, are included in the Nutrient Management Plan. SHGs per soil map unit are available through selection of the Soil Data Explorer and Soil Properties and Qualities (then select "Soil Qualities and Features") tabs once an Area of Interest has been defined in NRCS Web Soil Survey. If the Nitrogen Leaching Index > 10 for planned fields, appropriate conservation practices must be included in a conservation plan to prevent nitrogen from leaving the field via surface or subsurface runoff. Below are conservation crop management techniques and practices recommended for mitigation of nitrate losses (practices also documented in conservation plan): ooAoeYyoA1ov% -cover- page 2 NUTRIENT MANAGEMENT PLAN DEVELOPMENT The nutrient management plan has been developed to meet nutrient application rate criteria for all sources of nitrogen, phosphorus, potassium as specified by NRCS 590 Nutrient Management standard criteria. In addition to NCDA Agronomic Division soil test recommendations, or soil test recommendations made through similar guidelines, the plan is based on NC INMC approved values for realistic yield goals, nitrogen factors, phosphorus removal rates, default nutrient values for animal waste, plant availability coefficients for N, P, and K, and animal waste generation volumes where applicable. Approved values are found at: http:Anutrients. soil. ncsu. edufindex. htm Where manure is applied, farm records may also be used through a procedure provided in SIB 1217 Interagency Group guidance, available at: http://www.ncapr.aov/SWC/tech/1217committee ht ml For NC permitted animal operations, planning requirements for Plan "Amendments" (minor modifications) and "Revisions" (Major Modifications) are clarified by SIB 1217 Interagency Group Guidance. ADDITIONAL PHOSPHORUS -RELATED PLAN INFORMATION (Applicable when increases in Soil Test P are expected on the planned area) In NC, a field -specific Phosphorus Loss Assessment Tool (PLAT) evaluation is completed J in accordance with 590 Nutrient Management standard General Criteria requirements, and phosphorus must be applied in accordance with 590 standard Manure Phosphorus Application Rates. In addition to the basic plan components, plan information on PLAT categorical ratings, P drawdown strategies, and conservation practices to reduce P loss risk is required when increases in Soil Test P are expected on the planned area. Typically, this could occur when manure is consistently applied at Nitrogen -based rates. High levels of phosphorus in the surface soil layer have been linked to increasing risk of P loss through surface runoff and leaching. ❑ Increases in Soil Test P are expected on the planned area (not typical if P application made per soil test results). NC-590 Job Sheet May 2015 PLAT Categorical Ratings Information When soil test phosphorus continues to increase on a long term basis, PLAT may produce results that require P-based manure application planning and planning for no additional manure P. Conditions that will require P-based or no-P planning will be based on site specific resource conditions, which will facilitate data input into PLAT. PLAT categorical ratings that will require enhanced P application planning are: HIGH: P-based manure application is required (limited to P uptake in harvested crop biomass) VERY HIGH: No additional manure P or starter P application to be specified in nutrient management plan. Phosphorus Drawdown Strategy Information: Implementation of a phosphorus 'drawdown' strategy may be a consequence of PLAT results, or may be requested in order to lower soil test phosphorus levels. Should a reduction in soil test P be desired or necessary, the only currently proven method of substantial P 'drawdown' is to not apply manure - based P and to plant and harvest crops that utilize P currently present in the soil surface. Crop specific estimated annual P removal amounts are available on the NCSU Nutrient Management in NC website: htti)://nutrients.soil.ncsu.edu/vields/index.PhD Conservation Practices and Management Techniques to Reduce P Loss Potential: Conservation practices, especially those that prevent soil particle detachment and trap sediment at field edges are effective in preventing phosphorus movement from the planned site. Manure application techniques can also be applied to reduce P loss risk. These practices must be included in the conservation plan where determined PLAT risk = HIGH for planned fields. Consult the conservation plan developed in conjunction with the nutrient management plan for information on practices recommended to reduce phosphorus AND nitrogen loss risks. Application management techniques to reduce nutrient loss risk may be prescribed below: page 3 Long Term Strategy for Reduction of Soil P Levels: As noted in the P drawdown strategy section, the only currently proven method for reducing high levels of soil P is not applying P, paired with producing crops on the planned site that use existing soil P. Where soil P and PLAT evaluations indicate an increasing risk to water quality, substantially reducing soil P levels through crop uptake can take many years of implementation. When P is not applied, and existing soil P is used by crops, eventually, soil will become P deficient. Consult CES or NCDA Regional Agronomy specialists for additional information soil test P reduction timelines. Manure P produced in excess of crop requirements: Consult the nutrient management plan for a quantification of manure generated by the animal feeding operation that may exceed crop P requirements. "Manure Hauler" Information All manure waste applied on land owned by or controlled by the Animal Feeding Operation (AFO) owner or operator must be included in the nutrient management plan. The volume difference in total manure waste generated by the AFO and waste applied to land not owned or controlled by the producer must be accounted for in a nutrient management plan. General information on manure waste generated by an AFO to be applied to land not owned or controlled by the AFO owner or operator may be recorded as specified in the NC CLAMP Certification Sheet and Documentation Checklist or other supplemental documentation to the nutrient management plan. NRCS CNMP technical criteria require documentation of manure exports off the farm (this can be done below). The AFO owner/operator should provide the third party applicator with a current waste analysis in order to facilitate agronomic crop application of the facility's generated waste. Should land not owned or controlled by the AFO owner or operator be included in a nutrient management plan, the complete plan must meet 590 criteria. Type and Quantity of Animal Feeding Operation (AFO) manure generated by the facility: N/A Quantity of AFO manure generated to be exported off the farm for third party application: N/A RECORDKEEPING Waste reports from the NCDA & CS Agronomic Division, or equivalent, are acceptable sources of information for determining applied manure nutrient amounts for recordkeeping or crop budgeting purposes. Records must be maintained for at least 5 years, or for time and manner required by Permit for animal operations to document plan implementation and maintenance. As applicable, records include: • soil, plant tissue, water, manure, and organic by-product analyses resulting in recommendations for nutrient application, • quantities, analyses and sources of nutrients applied, • dates, and method(s) of nutrient applications, source of nutrients, and rates of application, • weather conditions and soil moisture at the time of application; lapsed time to manure incorporation; rainfall or irrigation event, • crops planted, planting and harvest dates, yields, nutrient analyses of harvested biomass, and crop residues removed, • dates of plan review, name of reviewer, and recommended changes resulting from the review, and • all enhanced efficiency fertilizer products used. Additional records for precision/variable rate sites must include: • maps identifying the variable application source, timing, amount, and placement of all plant nutrients applied, and • GPS-based yield maps for crops where yields can be digitally collected. • Documentation per field nitrogen application rates do not exceed RYE - based recommended rates • Documentation that applied phosphorus and potassium recommendations do not exceed recommended rates specified by soil tests. • For non -variable rate application of P & K, provide applied map with field boundaries indicating source, timing, method, and rate of all applications. • Where 'chlorophyll reader' technology is utilized, application records that nitrogen rates match RYE -based N rates as closely as possible. NC-590 Job Sheet May 2015 page 4 OPERATION AND MAINTENANCE The producer is responsible for safe operation and maintenance of this practice, including all equipment. Review the plan periodically to determine if adjustments or modifications to the plan are needed. In NC, animal operations permitting provisions may specify more frequent review periods. Adhere to the following operation and maintenance provisions: • Protect fertilizer and organic by-product storage facilities from weather and accidental leakage or spillage. • Properly calibrate application equipment to ensure uniform distribution of material at planned rates. • Workers should be protected from and avoid unnecessary contact with inorganic fertilizers and organic by-products. Extra caution must be taken when handling ammonia sources of nutrients, or when dealing with organic wastes stored in unventilated enclosures. • The disposal of material generated by the cleaning of nutrient application equipment should be accomplished properly. Excess material should be collected and stored or field applied in an appropriate manner. Excess material should not be applied on areas of high potential risk for runoff or leaching. • Disposal or recycling of nutrient containers should be done according to state and local guidelines or regulations.

December 18, 1996 USDA _ United States Department of Agriculture 360-CPS-1 Natural Resources Conservation Service CONSERVATION PRACTICE STANDARD WASTE FACILITY CLOSURE CODE 360 (no) DEFINITION The decommissioning of facilities, and/or the rehabilitation of contaminated soil, in an environmentally safe manner, where agricultural waste has been handled, treated, and/or stored and is no longer used for the intended purpose. PURPOSE This practice is used to accomplish one or more of the following purposes — 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 agricultural waste facilities or livestock production sites that are no longer needed as a part of a waste management system and are to be permanently closed or converted for another use. These facilities include liquid/dry waste storage facilities, confined animal housing, feedlots, livestock yards, or composting facilities. This practice applies where impoundments that are to be converted to fresh water storage meet current NRCS standards. Where structures that include agricultural waste storage, such as confined animal housing, are to be decommissioned, this practice will apply to the removal of the waste and rehabilitation of soil within the facility. This practice applies to remediation of soil contaminated by agricultural wastes that have been stored on - site. It does not apply to sites contaminated by materials that require the issuance of a hazardous waste permit, such as fuel or pesticides. CRITERIA General Criteria Applicable to All Purposes The closure shall comply with all Federal, State, and local laws, rules, and regulations including national pollutant discharge elimination system (NPDES) requirements. 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 visit the Field Office Technical Guide online by going to the NRCS website at April 2012 https://www.nres.usda.gov/ and type FOTG in the search field. USDA is an equal opportunity provider, employer, and lender. 360-CPS-2 Existing waste transfer components that convey to waste facilities or provide drainage from the facility area shall be removed and replaced with compacted earth material or otherwise rendered unable to convey waste. Remove manure, agricultural waste, and contaminated soil to the maximum extent practicable. All manure and agricultural waste that could negatively impact water and/or air quality or pose a safety hazard shall be removed as deemed practicable. All liquid, slurry, sludge, solid waste, and soil removed from the facility shall be utilized in accordance with NRCS Conservation Practice Standards, Nutrient Management, Code 590 and/or Waste Recycling, Code 633. Precautions (fencing and warning signs) shall be used where necessary to ensure that the facility is not used for purposes incompatible with the facility modification. Erosion and Pollution Control All disturbed areas shall be re -vegetated or treated with other suitable measures used to control erosion and restore the aesthetic value of the site. Sites, not suitable for re -vegetation through normal cropping practices, shall be vegetated in accordance with NRCS Conservation Practice Standard, Critical Area Planting, Code 342. Liquid and Slurry Waste Removal Liquid and slurry wastes shall be agitated and pumped to the maximum extent practicable. Water shall be added as necessary to facilitate the agitation and pumping. The wastewater shall be utilized in accordance with NRCS Conservation Practice Standard, Nutrient Management, Code 590 and/or Waste Utilization, Code 633. If the bottom of the lagoon or structure is above the water table at the time of closure and will support earth -moving equipment, it must be scraped. A qualified technical specialist must determine the soil stability for earth moving equipment. For lagoons or structures that are not to be scraped and those with bottoms documented to be below the water table at the time of closure, the depth of "agitated" waste material remaining in the lagoon or structure at the time of closure may not exceed a maximum depth of one (1) foot. Sludge Removal During sludge removal operations, the integrity of the liner, if one is present, shall be maintained. Sludge shall be removed to the maximum extent practicable and utilized in accordance with NRCS Conservation Practice Standard, Nutrient Management, Code 590 and/or Waste Utilization, Code 633. Impoundment Closure Three options are associated with the decommissioning of liquid waste impoundments. One of the following will be used. 1. Embankment impoundments (those with a depth of water at the design water level of three feet or more above natural ground) may be breached so that they no longer impound water. The embankment material can then be graded into the impoundment area, and the area vegetated for another use. Or the embankment may remain if the impoundment area surface has been sufficiently cleaned so that runoff leaving the site would not be considered as contaminated by the wastes. 2. Excavated impoundments maybe backfilled so that these areas maybe reclaimed for other uses. 3. Impoundments may be converted to fresh water storage. Embankment Impoundments Waste and sludge shall be removed from the impoundment before the embankment is breached. Concrete and flexible membrane liners shall be removed or rendered unable to impound water and properly disposed of. The slopes and bottom of the breach shall be stable for the soil material involved; however, the side slopes shall be no steeper than three horizontal to one vertical (3:1). NRCS, NC April 2012 360-CPS-3 Excavated Impoundments Concrete and flexible membrane liners shall be removed or rendered unable to impound water and properly disposed of. The backfill height shall exceed the height to the design finished grade by a minimum of 5 percent to allow for settlement. The top one foot of the backfill shall be constructed of the most impervious soil material readily available and mounded to shed rainfall runoff. Incorporate available topsoil where feasible to aid establishment of vegetation. Conversion to Fresh Water Storage The converted impoundment shall meet the requirements as set forth in the appropriate NRCS practice standard for the intended purpose. Where the original impoundment was not constructed to meet NRCS standards, the investigation for structural integrity shall be in accordance with National Engineering Manual (NEM) 501.23. When it is not practical to remove the sludge from a waste impoundment that is being converted to fresh water storage, the impoundment shall 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 impoundments that may be closed by the following alternate method. This alternative closure process consists of vacuum dredging the sludge and leaving the liquid. Impoundments 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 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 fullest extent practical on the slopes, but in no case shall there be more than 0.2 ft. of sludge in the bottom when finished. The impoundment 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). 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 Quality (DWQ) staff, or NRCS staff with a WUP designation as a technical specialist. A survey of the lagoon 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 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 Quality (DWQ), Division of Soil and Water Conservation (DSWC), or an NRCS Engineer or Civil Engineering Technician must verify that the sludge has been satisfactorily removed. Lagoons 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. Fabricated Liquid Waste Facilities If fabricated structures are to be demolished, disassembled or otherwise altered, it shall be done to such an extent that no water can be impounded. Disassembled materials such as pieces of metal shall be temporarily stored in such a manner that they do not pose a hazard to animals or humans until their final disposition. NRCS, NC April 2012 360-CPS-4 Demolished materials shall be buried on -site or moved off -site to locations designated by state or local officials. If buried on -site, the materials are to be covered with soil to a settled depth of at least one foot. The backfill height shall exceed the height to the design finished grade by a minimum of 5 percent to allow for settlement, and the backfill be sufficiently mounded such that runoff will be diverted from the site after the backfill settles. Dry Waste Storage or Treatment Facilities The soil at dry waste facilities such as confined animal housing, feedlots, livestock yards, or composting facilities with earthen floors must be evaluated. The evaluation shall include laboratory analyses of the soil profile for any nutrients for which specific information is needed to determine the required depth of rehabilitation. Soil samples shall be taken at multiple locations and depths within the facility. One sample per depth interval per acre of the area being decommissioned with a minimum of 3 samples per depth interval shall be taken. Samples taken for each specified sampling depth interval may be consolidated into a single set (e.g., 3 samples taken at the 0 to 6 inch depth interval may be consolidated into a single sample for testing). The samples shall be collected, prepared and tested in accordance with NRCS Conservation Practice Standard, Nutrient Management, Code 590. The results of the soil analysis will be used to prepare a plan to recover the site for its intended use. The following site appropriate options shall be utilized, if needed: • Adjust pH to restore desired crop growing conditions. • Select plants and erosion control practices to minimize phosphorus transport from the site and facilitate remediation of excessively high phosphorus levels. • Plant salt tolerant plants to restore the site to desired crop conditions. The harvested vegetation quality should be monitored for N, P, and K removal. Although in -situ processes are the preferred method for adjusting the soil conditions, removal of a portion of the soil may be necessary. The removed soil shall be land applied in accordance with NRCS Conservation Practice Standard, Nutrient Management, Code 590 and/or Waste Utilization, Code 633. Excavated areas shall be graded and or backfilled to shed rainfall and prevent ponding of runoff. Where feasible, available topsoil should be used to aid the establishment of permanent vegetation. CONSIDERATIONS Conduct pre -closure soil and water (surface and subsurface) testing to establish base line 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 the surface is covered by a dense mat of floating vegetation, pumping effort to empty waste impoundments may be reduced by first applying herbicide to the vegetation and then burning the residue. Appropriate permits must be obtained before burning. When burning is conducted, take necessary actions to ensure that smoke is managed to minimize impacts to downwind populations. 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 and 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. NRCS, NC April 2012 360-CPS-5 Minimize agitation of the wastes to only the amount needed for pumping to reduce the potential for release of air emissions. Soil to fill excavated areas should not come from important farmlands (prime, statewide, local, and/or unique). Waste facility closure may improve utilization and aesthetics of the farmstead. Breached embankments may detract from the overall aesthetics of the operation. Embankments should be removed and the site returned to its original grade. Disassembled fabricated structures may be suitable for assembly at another site. Care should be taken during closure to minimize damage to the pieces of the facility, particularly coatings that prevent corrosion of metal pieces. Measures should be taken during contractors' activities to minimize site erosion and pollution of downstream water resources. This may include such items as silt fences, hay bale 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. l7W_1,PYTI 11&32xal;I[d_Ai[90 Plans and specifications for the decommissioning of abandoned waste facilities and the rehabilitation of contaminated soil shall be in keeping with this standard and shall describe the requirements for applying the practice to achieve its intended purpose. At a minimum, include the following: 1. A plan view showing the location and extent of the practice. 2. Pertinent elevations of the closed facility and excavation limits. 3. Number, capacity, and quality of facility(ies) and estimate of soil volume to be moved. 4. Location of known utilities. 5. Requirements for salvage and disposal of structural materials. 6. Vegetative requirements. 7. Utilization Plan for animal wastes and soil. 8. Odor management or mitigation requirement. 9. Safety plan requirements. Note: Per Occupational Safety and Health Administration (OSHA) confined space entry protocol, personnel shall not enter confined space of an enclosed waste facility without breathing apparatus or taking other appropriate measures. OPERATION AND MAINTENANCE The proper decommissioning and rehabilitation of a waste facility should require little or no operation and maintenance. However, if it is converted to another use, such as a fresh water facility, operation and maintenance shall be in accordance with the needs as set forth in the appropriate NRCS conservation practice standard for the intended purpose.
