The subject project is located in Duplin County, North Carolina. To facilitate your review of the enclosed documentation, the following is an itemized breakdown: 1. One (1) original 'State Digester General Permit Application' application form. 2. One (1) copy of the engineering calculations. 3. One (1) copy of a detailed narrative of the Swine Digester Animal Waste Management System. 4. One (1) copy of the FEMA FIRM map labeled with the 'Proposed Digester Site'. 5. One (1) copy of the permit form Section 3.6 components. 6. One (1) full-size set of the engineering plans, as well as one (1) 11"x17" set. As marked in the 'State Digester General Permit Application' application form attached with this package, Section 3.3 of the form has not been filled out because there are no proposed swine treatment/storage structures for this project; one of the existing lagoons will be converted to an anaerobic digester. Influent sampling will be accomplished via sampling from the influent lift station or gravity main conveying flushed manure to the digester, where applicable. Effluent sampling will be accomplished via sampling from the level control wet well. Regarding usage of the biogas, the applicant plans to utilize the biogas produced from the facility to generate a renewable energy resource for export off the farm. Specific details of how the applicant plans to do this are not yet released, but the applicant plans to begin export of the renewable energy resource within 12 months of commencing construction. Regarding estimate of daily volume of biogas, the daily volume of biogas varies based on animal stocking numbers, animal age, and climatic variations. A gross estimate that is commonly used for in -ground, ambient temperature digesters is about 2 cubic feet of biogas per pig occupant in the farm per day; however, the actual amount of biogas produced by the farm may vary significantly given the considerations described above. Cavanaugh & Associates, P.A. PO Box 11197 Winston-Salem, NC 27116, 1-877-557-8923, www.covanaughsolutions.com Regarding emergency flare, an emergency flare will not be provided for the proposed farm. Rather, should the applicant need to dispose of excess biogas, the system operator will open one or more emergency vent ports to be installed as part of the HDPE digester cover system, and release the biogas. Please do not hesitate to contact our office should you have any questions, comments, or require any additional information. Regards, Cavanaugh & Associates, P.A. Kir0�0rit., Jeff P. Cappadona, P.E.

Upon flushing, Barns 1-11 will gravity flow waste through a 12" pipe to the Influent Lift Station (ILS). The influent lift Station will utilize two 10 hp GEA pumps, with a typical flow of approx. 590 gpm (1 pump) through an 8" HDPE (DR 17) forcemain into the anaerobic digester ('Lagoon C'). After treatment in the anaerobic digester (814,530 cubic feet of total volume, 682,268 cubic feet at Operating Level), effluent will gravity flow through the 12" digester outlet pipe to the level control station (LC); the Level Control Station will utilize two 10 hp GEA pumps, with a typical flow of approx. 590 gpm through a 6" HDPE (DR 17) forcemain to existing 'Lagoon B'.

The plant nutrients in the animal waste should be used to reduce the amount of commercial fertilizer required for the crops in the fields where the waste is to be applied. This waste utilization plan uses nitrogen as the limiting nutrient. Waste should be analyzed before each application cycle. Annual soil tests are strongly encouraged so that all plant nutrients can be balanced for realistic yields of the crop to be grown. Several factors are important in implementing your waste utilization plan in order to maximize the fertilizer value of the waste and to ensure that it is applied in an environmentally safe manner: 1. Always apply waste based on the needs of the crop to be grown and the nutrient content of the waste. Do not apply more nitrogen than the crop can utilize. 2. Soil types are important as they have different infiltration rates, leaching potentials, cation exchange capacities, and available water holding capacities. 3. Normally waste shall be applied to land eroding at less than 5 tons per acre per year. Waste may be applied to land eroding at 5 or more tons per acre annually, but less than 10 tons per acre per year providing that adequate fitter strips are established. 4. Do not apply waste on saturated soils, when it is raining, or when the surface is frozen Either of these conditions may result in runoff to surface waters which is not allowed under DWR regulations. 5. Wind conditions should also be considered to avoid drift and downwind odor problems. 6. To maximize the value of the nutrients for crop production and to reduce the potential for pollution, the waste should be applied to a growing crop or applied not more than 30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or disking will conserve nutrients and reduce odor problems. 1 of 11 This plan is based on the waste application method shown above_ If you choose to change methods in the future, you need to revise this plan. Nutrient levels for different application methods are not the same. The estimated acres needed to apply the animal waste is based on typical nutrient content for this type of facility. In some cases you may want to have plant analysis made, which could allow additional waste to be applied. Provisions shall be made for the area receiving waste to be flexible so as to accommodate changing waste analysis content and crop type. Lime must be applied to maintain pH in the optimum range for spec crop production. This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC 2H _0217 adopted by the Environmental Management Commission.

The farm should produce adequate plant available nitrogen to satisfy the requirements of the crops listed above. The applicator is cautioned that P and K may be over applied while meeting the N requirements. In the future, regulations may require farmers in some parts of North Carolina to have a nutrient management plan that addresses all nutrients_ This plan only addresses nitrogen. In interplanted fields ( i.e. small grain, etc, interseeded in bermuda), forage must be removed through grazing, hay, and/or silage. Where grazing, plants should be grazed when they reach a height of six to nine inches. Cattle should be removed when plants are grazed to a height of four inches. In fields where small grain, etc, is to be removed for hay or silage, care should be exercised not to let small grain reach maturity, especially late in the season (i_e_ April or May). Shading may result if small grain gets too high and this will definitely interfere with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen being utilized_ Rather than cutting small grain for hay or silage just before heading as is the normal situation, you are encouraged to cut the small grain earlier. You may want to consider harvesting hay or silage two to three times during the season, depending on the time small grain is planted in the fall. The ideal time to interplant small grain, etc, is late September or early October. Drilling is recommended over broadcasting. Bermudagrass should be grazed or out to a height of about two inches before drilling for best results.

Actual total acres in the fields listed may, and most likely will be, more than the acres shown in the tables. See attached map showing the fields to be used for the utilization of animal waste. 4of11 SLUDGE APPLICATION: The following table describes the annual nitrogen accumulation rate per animal in the lagoon sludge Farm Specifications PAN/yr/animal Farm Totallyr Farrow to Wean 0.8 Farrow to Feeder 0.96 Farrow to Finish 3.9 Wean to Feeder 0.07 Wean to Finish 027 10496 Feeder to Finish 0.34 3568.64 Gilts 0.39 Boars 0.55 The waste ufir¢ation plan must contain provisions for periodic land application of sludge at agronomic rates. The sludge will be nutrient rich and will require precautionary measures to prevent over application of nutrients or other elements. Your production facility will produce approximately 3568.64 pounds of plant available nitrogen per year and will accumulate in the lagoon sludge based on the rates of accumulation listed above. If you remove the sludge every 5 years, you will have approximately 17843.2 pounds of plant available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the rate of 300 pounds of nitrogen per acre, you will need 59 acreas of land. If you apply the sludge to corn at a rate of 125 pounds per acre, you will need 142.7456 acres of land. Please note that these are only estimates of the PAN produced and the land required to utilize that PAN. Actual values may only be determined by sampling the sludge for plant available nitrogen content prior to application Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific application fields designated for sludge application at time of removal_ APPLICATION OF WASTE BY IRRIGATION: The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation such that runoff or ponding occurs. This rate is limited by initial soil moisture content, soil structure, soil texture, water droplet size, and organic solids. The application amount should not exceed the available water holding capacity of the soil at the time of irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of the crop. If surface irrigation is the method of land application for this plan, it is the responsibility of the producer and irrigation designer to ensure that an irrigation system is installed to properly irrigate the acres shown in the preceding liable. Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid. 'This is the maximum application amount allowed for the soil assuming the amount of nitrogen allowed for the crop is not over applied. In many situations, the application amount shown cannot be applied because of the nitrogen limitaion_ The maximum application amount shown can be applied under optimum soil conditions. Your facility is designed for > 180 days of temporary storage and the temporary storage must be removed on the average of once every 6 months. In no instance should the volume of the waste stored in your structure be within the 25 year 24 hour storm storage or one foot of freeboard except in the event of the 25 year 24 hour storm. It is the responsibility of the producer and waste applicator to ensure that the spreader equipment is operated properly to apply the correct rates to the acres shown in the tables. Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid. Call your technical specialist after you receive the waste analysis report for assistance in determining the amount of waste per acre and the proper application prior to applying the waste. 5of11 Application Rate Guide The following is provided as a guide for establishing application rates and amounts.

Any discharge of waste which reaches surface water is prohibited. 2 There must be documentation in the design folder that the producer either owns or has an agreement for use of adequate land on which to properly apply the waste. If the producer does not 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 Utilization Plan when there is a change in the operation, increase in the number of animals, method of application, recieving crop type, or available land. 3 Animal waste shall be appried to meet, but not exceed, the nitrogen needs for realistic crop yields based upon soil type, available moisture, historical 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). 5 Odors can be reduced by injecting the waste or disking after waste application. Waste should not be applied when there is danger of drift from the 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). 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. 8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the surface is frozen. 9of11 NUTRIENT UTILIZATION PLAN REQUIRED SPECIFICATIONS 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. 10 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 to wells. 13 Animal waste shall not be applied closer than 200 feet of dwellings other than those owned by the landowner. 14 Waste shall be applied in a manner not to reach other property and public right-of-ways. 15 Animal waste shall not be discharged into surface waters, drainageways, or wetlands by discharge or by over -spraying. Animal waste may be applied to prior converted 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 washdown facilities, showers, toilets, sinks, etc., shall not be discharged into the animal waste management system. 10 of 11 Total Fld 7 = 12.90 Ac.

NUTRIENT UTILIZATION PLAN REQUIRED SPECIFICATIONS 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. 20 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 soil 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 a minimum of five years. 23 Dead animals will be disposed of in a manner that meets North Carolina regulations.

This amendment shall be placed with the current NUP for this farm. W'lVe.,� z-r-'r4l? Owner/Manager Date Technical Specialist Date Updated Crop Management Practices for Bermuda Winter Overseed This document, as approved by the Interagency Nutrient Management Committee on October 10. 2017, hereby modified the July 13. 1998 Memorandum "Crop Management Practices for Select Forages Used in Waste Management". This modification updates the application window protocol for the 100 lb Nitrogen PAN rate for both Cereal Rye and Annual Ryegrass, as well as winter small grains. • Farms utilizing the 100 lbs./ac PAN rate for the overseed are allowed to apply no more than 50 lbs./ac PAN from October 1 through December 31 and no more than 50 lbs./ac PAN from January 1 through March 31. • Applications made during the months of December and January cannot exceed the combined total of 25 lbs./ac PAN for the two -month period. • The last application of animal waste is to be applied to the bermuda crop prior to September 30. • The PAN rate for grazed systems must be reduced by 25%. All other requirements of the July 13, 1998 Memorandum continue to apply. Those requirements include but are not limited to: • Cereal rye and annual ryegrass should be planted by October 15 to provide the best opportunity to get winter growth. • A harvest is required prior to heading or April 7, whichever comes first, for both cereal rye and annual ryegrass. This is necessary to minimize the potential for shading of emerging bermuda and reducing its yield. To favor the production of bermuda, additional harvest of annual ryegrass will be required when the ryegrass canopy reaches 12-15 inches height. These management requirements shall also apply to overseeded winter small grain. Nov 16, 2017 Animal Waste Utilization Agreement Smithfield Hog Production Division Farm 202.93 I, Bill Burch, hereby give Smithfield Hog Production Division permission to apply animal waste from the waste utilization system on 148.18 acres of my land for the duration of time specified below. I understand that this waste contains nitrogen, phosphorous, and other trace elements and when properly applied should not harm my land or crops. I also understand that the use of waste will reduce my overall needs for commercial fertilizer, and that Nitrogen limitations exist based on individual farm Waste Utilization Plans. After the completion of animal waste application, Smithfield HPD shall provide said Landowner / Farmer with a Nitrogen total of animal waste derived nutrients vs. remaining nutrients allowed in the Waste Utilization Plan. This lease will stand year over year after the end of the lease agreement, unless the Landowner or Smithfield HPD provides written notification no later than 90 days from termination date.

Murphy -Brown, LLC Engineering EMERGENCY ACTION PLAN PHONE NUMBERS DIVISION OF WATER QUALITY (DWQ) EMERGENCY MANAGEMENT SERVICES (EMS) SOIL AND WATER CONSERVATION DISTRICT (SWCD) NATURAL RESOURCES CONSERVATION SERVICE (NRCS) COOPERATIVE EXTENSION SERVICE (CES) This plan will be implemented in the event that wastes from your operation are leaking, overflowing or running off site. You should not wait until wastes reach surface waters or leave your property to consider that you have a problem. You should make every effort to ensure that this does not happen. This plan should be posted in an accessible location for all employees at the facility. The following are some action items you should take. 1. Stop the release of wastes. Depending on the situation, this may or may not be possible. Suggested responses to some possible problems are listed below. A. Lagoon overflow - possible solutions are: a) Add soil to berm to increase elevation of dam. b) Pump wastes to fields at an acceptable rate. c) Stop all flow to the lagoon immediately. d) Cali a pumping contractor. e) Make sure no surface water is entering lagoon. B. Runoff from waste application field -actions include: a) Immediately stop waste application. b) Create a temporary diversion to contain waste. c) Incorporate waste to reduce runoff. d) Evaluate and eliminate the reason(s) that cause the runoff. e) Evaluate the application rates for the fields where runoff occurred. C. Leakage from the waste pipes and sprinklers - action include: a) Stop recycle pump. b) Slop irrigation pump. c) Close valves to eliminate further discharge. d) Repair all leaks prior to restarting pumps. D. Leakage from flush systems, houses, solid separators - action include: a) Stop recycle pump. b) Stop irrigation pump. c) Make sure siphon occurs. d) Stop all flow in the house, flush systems, or solid separators. Leakage from base or sidewall of lagoon. Often this is seepage as opposed to flowing leaks - possible action: a) Dig a small sump or ditch from the embankment to catch all seepage, put in a submersible pump, and pump back to lagoon. b) If holes are caused by burrowing animals, trap or remove animals and fill holes and compact with a clay type soil. c) Have a professional evaluate the condition of the side walls and the lagoon bottom as soon as possible. 2. Assess the extent of the spill and note any obvious damages. a. Did the waste reach surface waters? b. Approximately how much was released and for what duration? c_ Any damage notes, such as employee injury, fish kills, or property damage? d. Did the spill leave the property? e. Does the spill have the potential to reach surface waters? f. Could a future rain event cause the spill to reach surface waters? g. Are potable water wells in danger (either on or off the property)? h. How much reached surface waters? 3. Contact appropriate agencies. a_ During normal business hours call your DWQ regional office; Phone #, After hours, emergency number (919) 733-3942. Your phone call should include: your name, facility number, telephone number, the details of the incident from item 2 above, the exact location of the facility, the location or direction of the movement of the spill, weather and wind conditions. The corrective measures that have been under taken, and the seriousness of the situation. b. If the spill leaves property or enters surface waters, call local EMS phone number. c. Instruct EMS to contact local Health Department. d. Contact CE's phone number, local SWCD office phone number and the local NRCS office for advice / technical assistance phone number. 4. If none of the above works tali 911 or the Sheriff's Department and explain your problem to them and ask the person to contact the proper agencies for you. 5. Contact the contractor of your choice to begin repair or problem to minimize offsite damage. a. Contractors Name: b. Contractors Address: c . Contractors Phone: Om 6. Contact the technical specialist who certified the lagoon (NRCS, Consulting Engineer, etc.) a. Name: Sr.�> �•�;c�J Fo�dS, b. Phone: `lib)`I 3 3 7. Implement procedures as advised by LDWQ and technical asswtance agencies to rectify the damage, repair the system, and reassess the waste management plan to keep problems with release of wastes from happening again.

Primary Secondary Routine Mortality Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal death. The burial must be at least 300 feet from any flowing stream or public body of water (G.S.106-403). The bottom of the burial pit should beat least one foot above the seasonal high water table. Attach burial location map and plan. Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC 13B .0200. Rendering at a rendering plant licensed under G.S. 106-168.7. Complete incineration according to 02 NCAC 52C .0102. A composting system approved and permitted by the NC Department of Agriculture & Con- sumer Services Veterinary Division (attach copy of permit). If compost is distributed off -farm, additional requirements must be met and a permit is required from NC DEQ. In the case of dead poultry only, placing in a disposal pit of a size and design approved by the NC Department of Agriculture & Consumer Services (G.S. 106-549.70). ❑ Any method which, in the professional opinion of the State Veterinarian, would make possible the salvage of part of a dead animal's value without endangering human or animal health. (Written approval by the State Veterinarian must be attached). Mass Mortality Plan Mass mortality plans are required for farms covered by an NPDES permit. These plans are also recommended for all animal operations. This plan outlines farm -specific mortality man- agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup- ports a variety of emergency mortality disposal options; contact the Division for guidance. • A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated when numbers of dead animals exceed normal mortality rates as specified by the State Veterinarian. • Burial must be done in accordance with NC General Statutes and NCDA&CS Veterinary Division regulations and guidance. • Mass burial sites are subject to additional permit conditions (refer to facility's animal waste management system permit). • In the event of imminent threat of a disease emergency, the State Veterinarian may enact additional r cedures or measures for disposal according to G.S. 106-399.4 Signatu Signature of Technical Specialist 1.S-n Date Date Anaerobic Digester System O&M Table of Contents I.

Biogas - Produced by anaerobic digestion, and is typically comprised of approximately 55% methane (the primary constituent of natural gas), with the remainder being mostly carbon dioxide (COA. Anaerobic Digester System O&M Page 2 of 16 II. Introduction The proposed swine manure biogas project uses anaerobic digestion of hog barn waste to produce biogas (consisting of approximately 65% methane, which is the primary constituent of natural gas) which is collected, conditioned, and ultimately injected into the utility's natural gas pipeline. Each hog farm site includes influent collection piping from the hog barns, an anaerobic digester or covered lagoon, a digester mixing system, a biogas conditioning system to remove moisture, a back-up flare unit, and a biogas transfer pipe leading to the Gas Upgrading System (GUS). The anaerobic digesters at each farm site include an HDPE membrane cover to capture the biogas generated by the anaerobic digestion process. The anaerobic digester is partially mixed by pumping, and provides sufficient detention time to effectively reduce the volatile suspended solids in the raw waste by anaerobic digestion. The reduction of volatile solids through microbial processes produces an energy -rich biogas, which is a valuable commodity. There are two (2) types of solids found in liquid waste: organic and inorganic. The inorganic solids are "non -treatable," but they are normally present in such small quantities that they are considered insignificant in the treatment process. However, excessive quantities of sand, grit, clay, etc. can cause the need to pump out the digester more often. The organic solids will break down and decompose by biochemical reduction. The bacteria that is grown and maintained in the system are harmless anaerobic and anoxic bacteria. These same bacteria are provided by nature and are found in streams, lakes, and in the soil to destroy dead plants and animals. The difference is that in the treatment process, man has provided an ideal environment for a concentration of these bacteria to feed and grow; thus, the biological action is greatly accelerated. Raw wastes are the food for the bacteria in the system. The anaerobic digester contains certain populations of bacteria that do not require the presence of oxygen. In addition to the information covered by this manual, the system operator should become familiar with the characteristics of the wastewater being treated and with local, state, and federal laws which may apply to the operation of the system. Design Flow - The waste collection system, influent pump station (where necessary), and anaerobic digester systems have been designed to handle the Average Daily Flow Rate (ADF) of the farms in which they are connected, including the manure and wastes generated by the animals, flushing liquids, and other wastes typical of confined swine animal housing. All treatment units were designed for the Design Flow for continuous, seven (7) days per week operation. III. Description of the Operational Components Below are listed the major component operations. 1) Gravity Collection Pipe Anaerobic Digester System O&M Page 3 of 16 The gravity collection pipe receives the flushed waste from the hog barns and directs that waste to the influent pump station (or mixing pump station, where applicable). During normal operation, the pipe should be free -flowing, with no clogs present, in order to transport waste to the influent pump station or other downstream processes. The gravity collection pipe includes a series of clean -outs that provide access to the gravity collection pipe for removal of a clog or blockage via use of a sewer snake or similar apparatus should the need arise. Sending flushed waste from the hog barns to the gravity collection pipe is the farmer's responsibility. The operator of the biogas system should periodically check each hog barn waste outlet to ensure that there are no overflows, clogs, etc. The influent pump station includes an analog run-time meter for each pump, which can be monitored by the operator to ensure the pumps are operating for sufficient times to indicate proper flushing by the farm owner. 2) Influent Pump Station (where necessary) The influent pump station receives waste from the gravity collection pipe and pumps that waste to the anaerobic digester via buried forced main. The waste enters the digester at the opposite end of the digester outlet (so "new' waste must flow through the curtain baffle system of the digester, resulting in effective treatment of the waste). During normal operation, the pump station will automatically cycle on and off based on the liquid level in the wet well, which is triggered by 4 floats. The lowest float is the "pump off' float, and is set at approximately 12" above the bottom of the wet well. The pump station should not run if the liquid level is below this float. The 2nd lowest float is the "lead pump on" float, and is set at an elevation approximately 2" below the inlet pipe invert, and above the "lead pump off' float. When the liquid level is above this float, only one pump will run at any given time, where the pumps will alternate between cycles (Pump 1 will run while Pump 2 is off, and in the next cycle Pump 2 will run while Pump 1 is off, and so on). The 3rd lowest float is the "lag pump on" float, and is set approximately 6" above the "lead pump on" float. If the liquid level fills above this float, then both pumps will run until the "pump off' float is disengaged. The 4th and highest float is the "high level alarm" float. When the liquid level is above this float, an audible and visual alarm is triggered to alert the operator system that there is a problem that has prevented pump operation. The pipe from each of the two pumps goes through a check valve (which only allows the liquid to travel in one direction) and a plug valve (normally open, but can be closed when needed, such as when servicing the upstream pump). The two pipes join together by a tee, and the downstream pipe leads to the inlet of the digester. Anaerobic Digester System O&M Page 4 of 16 During normal operation, the pumps may run several times an hour to pump waste to the anaerobic digester. Only one pump will run at any given time, normally, where the pumps will alternate between cycles (Pump 1 will run while Pump 2 is off, and in the next cycle Pump 2 will run while Pump 1 is off, and so on). It is not uncommon, however, for both pumps to operate during higher inlet flows. The pumps can also be controlled manually, if desired, or in times of troubleshooting, etc. The control panel next to the pump station includes toggle switches for each pump, which can be set to either (1) Auto (for normal float -based operation), (2) Off, or (3) "Hand" (i.e., manual operation). The alternating of pumps can also be changed within the control panel, where a toggle switch allows the operator to choose "Lock 1", "Alternate", or "Lock 2". During normal operation, the toggle switch will remain at "Alternate" in order to alternate the pumps between pumping cycles, but the operator can choose to lock the use of Pump #1 or lock the use of Pump #2 if needed. In the event of a pipe clog or pump failure, the waste will flow through the gravity "digester bypass" pipe connecting the interior of the pump station to the existing lagoon at an elevation below the top of the wet well, which will avoid overflow of the pump station. Note: Some farms do not have Influent Pump Stations; rather than using an Influent Pump Station, the waste flows from the barns to the Mixing Pump Station, which is further described below. 3) Anaerobic digester The anaerobic digester receives all raw wastes from the hog barns. The complex organic wastes are broken down to simpler compounds by the anaerobic digestion process. As a part of the anaerobic process, bio gases (including methane, carbon dioxide, and hydrogen sulfide) are produced. These gases are captured by an impermeable cover and then directed to the biogas conditioning system for dehydration and pressurization. The gases are collected in perforated piping underneath the cover, which are connected to a main pipe that connects to the conditioning system. The wastes are held for about 45 days to allow the biological process to complete. The sludge that settles at the bottom of the digester is periodically removed by connecting portable pipes and pumps to the sludge removal pipes in the digester, and disposed of by permitted means on the farm or by a contract sludge hauler. During normal operation, the digester cover will likely be "inflated" like a balloon due to the biogas that's trapped beneath. The cover should be free of excessive accumulation of rainwater, and should not show signs of any damage or leaks. The presence of foul odor, a strong wastewater smell, or "dirty" water on the cover may indicate that there is a leak. If such odors or dirty water are observed, the operator should carefully inspect the cover for leaks, and take action to repair the cover temporarily with adhesive tape. Temporary repairs should be followed with a permanent repair or patch as soon as possible. Anaerobic Digester System O&M Page 5 of 16 4) Mixing Pump Station The mixing pump station slowly mixes the waste that has been collected in the anaerobic digester, which provides for more efficient methane production than would be achievable without any mixing. During normal operation, the pumps will run at the same time for several hours per day to mix the waste in the anaerobic digester. A common schedule for the pumps would be 6 hours on, then 6 hours off, and so on. The pumps can also be controlled manually, if desired, or in times of troubleshooting, etc. The control panel next to the pump station includes toggle switches for each pump, which can be set to either (1) Auto (for normal operation), (2) Off, or (3) "Hand" (i.e., manual operation). 5) Effluent Pump Station (where necessary) The effluent pump station receives liquids from the anaerobic digester and pumps that waste to the downstream influent storage lagoon via buried forced main. The liquid enters the effluent pump station at the opposite end of the digester inlet (so "new" waste must flow through the curtain baffle system of the digester, resulting in effective treatment of the waste). During normal operation, the pump station will run based on the liquid level in the wet well, which is triggered by 4 floats. The lowest float is the "pump off' float, and is set at approximately 12" above the bottom of the wet well. The pump station should not run if the liquid level is below this float. The 2nd lowest float is the "lead pump on" float, and is set at an elevation approximately 2" below the inlet pipe invert, and above the "lead pump off' float. When the liquid level is above this float, only one pump will run at any given time, where the pumps will alternate between cycles (Pump 1 will run while Pump 2 is off, and in the next cycle Pump 2 will run while Pump 1 is off, and so on). The 3rd lowest float is the "lag pump on" float, and is set approximately 6" above the "lead pump on" float. If the liquid level fills above this float, then both pumps will run until the "pump off' float is disengaged. The 4th and highest float is the "high level alarm" float. When the liquid level is above this float, an audible and visual alarm is triggered to alert the operator via telemetry system that there is a problem that has prevented pump operation. The pipe from each of the two pumps goes through a check valve (which only allows the liquid to travel in one direction) and a plug valve (normally open, but can be closed Anaerobic Digester System O&M Page 6 of 16 when needed, such as when servicing the upstream pump). The two pipes join together by a tee, and the downstream pipe leads to the inlet of the digester. During normal operation, the pumps may run several times an hour to pump waste to the lagoon. Only one pump will run at any given time, normally, where the pumps will alternate between cycles (Pump 1 will run while Pump 2 is off, and in the next cycle Pump 2 will run while Pump 1 is off, and so on). It is not uncommon, however, for both pumps to operate during higher inlet flows. The pumps can also be controlled manually, if desired, or in times of troubleshooting, etc. The control panel next to the pump station includes toggle switches for each pump, which can be set to either (1) Auto (for normal float -based operation), (2) Off, or (3) "Hand" (i.e., manual operation). The alternating of pumps can also be changed within the control panel, where a toggle switch allows the operator to choose "Lock 1", "Alternate", or "Lock 2". During normal operation, the toggle switch will remain at "Alternate" in order to alternate the pumps between pumping cycles, but the operator can choose to lock the use of Pump #1 or lock the use of Pump #2 if needed. The gravity outlet of the anaerobic digester leads to the inlet of the effluent pump station, and the invert is set at the freeboard of the digester so that the digester maintains a constant level. The inlet pipe to the effluent pump station should remain submerged in water at all times to prevent the escape of gases from beneath the digester cover. Note: Some farms do not have Effluent Pump Stations; rather than using an Effluent Pump Station, the waste gravity flows from the anaerobic digester to the lagoon. 6) Storage Basin The effluent of the anaerobic digester flows from the anaerobic digester outlet pipe to the storage basin. The storage basin is used to store the treated effluent subsequent to anaerobic digestion. The individual farm owners are responsible for the operation and maintenance of the storage basins. However, as this is a critical part of the integrated system, the Operator should note any abnormal operation of the storage basin, such as leaks or excessive liquid level, and communicate such observations to the farm owner. During normal operation, the storage basin will most often appear to be inactive. Waste will periodically flow from the anaerobic digester outlet pipe into the storage basin via gravity. The outlet pipe from the anaerobic digester into the storage lagoon should remain submerged at all times to prevent the escape of gases from beneath the digester cover. As such, it is not uncommon for the pipe to turn down and follow the direction of the inner slope of the lagoon to ensure submergence during times when the lagoon liquid level may be low due to normal pumping and irrigation activities. 7) Biogas Conditioning System Anaerobic Digester System O&M Page 7 of 16 The Biogas conditioning system receives biogas from the anaerobic digester and removes moisture from the biogas by means of compression and heat exchangers. This system will be managed by a 3rd party, but the information is included in this O&M for reference. The biogas from the anaerobic digester is commonly at 100% relative humidity; the biogas is purported to be near 6% relative humidity after going through the conditioning system. The moisture that is removed should be directed back to the digester mixing pump station or other suitable reception pipe for proper management of the condensate. During normal operation, the conditioning system should run without any need for input from the system operator. Audible and visual alarms will indicate issues with the system. The discharge pressure and flow rate can be manipulated by the operator through adjustment of the pressure regulator on the bypass line and through adjustment of the variable frequency drive. The automatic shutoff feature, whereby the operator can set the vacuum pressure shutoff point. As the biogas conditioning skid approaches this setpoint, it will automatically reduce blower or compressor speed to seek a flowrate that matches the biogas production. If the vacuum pressure exceeds the setpoint, the biogas conditioning skid will shutdown and trigger an alarm to the operator via telemetry system. 8) Flare During normal operation, the flare located at each farm should not necessary. In times of need, such as catastrophic failure of the biogas conveyance pipeline, the flare may need to be operated to consume excess accumulated biogas from the digester. The flare is not an automated system, and the Operator must articulate the biogas piping control valving to direct biogas from the digester to the flare, and ignite the flare. Care must be taken by the Operator in igniting the flare, as biogas is highly flammable. Each flare also has a condensate trap manhole. Contained inside is a small PVC drain pipe and PVC drain valve. The PVC drain valve should remain closed at all times unless the Operator is removing condensate. Should the valve be left open, biogas will escape from the piping. Periodically, and at a frequency determined appropriate by the Operator, these condensate traps will be opened momentarily to drain and remove any condensate collected in the piping. It is recommended that the condensate drain valve only be opened when the biogas piping is pressurized, as should the valve be opened under no pressure, ambient air may enter the biogas piping and challenge biogas upgrading by the GUS. 9) Transfer Pump The transfer pump transfers accumulated effluent among available storage basins as the farm owner deems necessary to optimize effluent storage. The transfer pumps are simply and manually operated through use of a local disconnect. Under normal Anaerobic Digester System O&M Page 8 of 16 circumstances, the transfer pump will only be used periodically and infrequently by the farm owner. 10) Stormwater Removal Pump A stormwater removal pump is kept at each digester site in order to remove accumulated rainwater from the top of the basin cover. The pump can be powered by any standard 120v outlet that's available nearby, such as the accessory outlet installed adjacent to the digester mixing pump station. The pump should be placed in a low spot on top of the cover, and the pump outlet should lead to an appropriate area for stormwater discharge (on some sites, pipes have been placed to easily receive the pump outlet pipe, which leads to the natural stormwater drainage swales on the property). IV. Description of Anticipated Maintenance Once the system has been started up and is operating efficiently, very little maintenance will be required. Simple tests should be periodically performed to evaluate the performance of the wastewater treatment components, and the system components visually inspected daily. A well -operated, properly adjusted, system will exhibit the following visible signs of proper maintenance: • All pipes should be intact and watertight. • The pumps should be nearly silent with little to no vibration. • The anaerobic digester should be free of excessive accumulation of rainwater. • Accumulated rainwater may be removed with a portable sump pump. The pumped water may be discharged safely on adjacent vegetated areas, or used for a more beneficial purpose as permitted. • The anaerobic digester cover should be free of any tears, punctures, or failures. • There should be no strong odors coming from the digester or flare. • The storage basin should be clean and free of floating debris. The liquid should be clean and clear. A. Routine System Maintenance Instructions For optimum system operation and maximum treatment efficiency, daily maintenance is necessary. In addition to the daily maintenance, all mechanical equipment should be cleaned weekly and lubricated as often as needed, as specified in the operations and maintenance manual for each piece of equipment provided by the equipment manufacturer. The farm owner will need to periodically remove accumulated sludge from the anaerobic digester. Accumulated sludge may be removed via the anaerobic digester mixing pumps. To use these pumps for sludge removal, the system operator should cease mixing pump operation 48 hours prior to the date of desired sludge removal to allow for settling of heavier sludge to the pump inlet. A quick disconnect fitting is provided for each mixing pump that will facilitate the connection of the pump discharge to sludge application Anaerobic Digester System O&M Page 9 of 16 equipment as chosen by the farm owner, such as slurry tanks or umbilical hose application systems. All sludge applications should be done in accordance with the approved waste utilization plan and nutrient management plan for the farm or hauled via tanker to an approved application site by a contract sludge hauler. Typically, a small amount of sludge will need to be removed from the anaerobic digester every other year. The system operator can monitor sludge accumulation via the inspection ports on top of the digester cover. A pipe or gauge with graduated markings used to determine depth may be used to assess the sludge depth in the digester. Care should be taken when inserting the gauge or pipe to not apply excessive pressure or otherwise puncture the digester liner. Sludge accumulation should be assessed on an annual basis by the system operator. As the digester cover typically accumulates biogas, care should also be taken by the operator to remove as much accumulated biogas as possible prior to opening the inspection port and measuring sludge accumulation. As biogas production slows during cold weather, it is recommended that this measurement occur during the winter when biogas accumulation is at a minimum. After completion of sludge removal activities using the anaerobic digester mixing pumps, the operator should reconnect all fittings and piping as found prior to the sludge removal and re-engage the digester mixing pumps operation in accordance with the schedule and manner in which they had been previously operated. See Appendix C of this document for an operations and maintenance checklist (daily, monthly, quarterly, semi-annually, annually). B.
