The subject project is located in Duplin County, North Carolina. The digester constructed on this property will meet setback parameters as required per the Swine Farm Siting Act. The digester is beyond 1500 ft from any occupied residence, 2500 ft. from any public building, beyond 500 ft. from property lines, and beyond 500 ft. from any public water source. Digester influent and effluent will be sampled from wet wells on site per the Sampling Protocol and Schedule document in this package. The digester water level will be monitored by a level gauge installed in the digester -lagoon transfer wet well. The digester will generate approximately 40,500 SCF of gas per day. This biogas is intended to be used within 6 months of beginning to collect gas. A portable flare unit will be connected to an emergency vent at the digester if needed. Spare parts for the gas upgrading systems will be kept on the shelf so readily available as needed. The digester cover will be provided with emergency vents which are strategically located away from barns/public but still provide access for operators. Safety procedures for venting covers are called out in the 0&M document. See Narrative for more information. Per the Air Permit Applicability Request for Register 1 cluster of farms, submitted to NCDEQ Division of Air Quality, the annual emission rates from the gas upgrading system associated with this farm are below the thresholds indicated in 15A NCAC 02Q.0102(d) and therefore does not require an air permit. 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.

ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS 27007 - HOG PACK 1 Digester Narrative Monarch Bioenergy LLC — Register, NC Swine RNG Project A1000 Digester Narrative R&A Project RA270-23 Issued 240827 Farm will utilize existing barns with slotted floors over flushing pits to collect manure. The farm operators use pull plug system and recycle water for flushing to manage the animal manure. As part of this current project, a new anaerobic lagoon digester will be installed, and the animal manure will be redirected to the new digester. After treatment in the in anaerobic digester, the effluent will flow into the existing lagoon. There is no change to the existing farm operations, nor the volume of wastes generated. The effluent water will be recycled back to the barn for pit recharge or irrigated in accordance with the existing Waste Utilization Plan (WUP). Upon flushing, the wastewater from the barns will be directed into a properly designed lift station through a 12-inch diameter gravity pipe header. There will be two pumps in the lift station wet well and each pump is designed for 100% of the design flow. The lift station pump at Hog Pack 1 Barns 1-3 will be 15 HP GEA pump, designed for a flow of 545 gallons/minute, through 6-inch diameter, HDPE SDR 17 force -main into the new anaerobic lagoon digester. Upon flushing Hog Pack 1 Barns 4-6, the wastewater will be directed through a 12-inch diameter gravity pipe header directly to the digester. The approximate dimensions of the new anaerobic lagoon digester are 330 feet by 170 feet with a total volume of 477,936 cubic feet and a treatment capacity of 371,640 cubic feet at operating level. Before the excavation, the project area is stripped approximately 6 inches of topsoil and will be stockpiled. Embankment material will be free of sod, roots, and other objectionable material. The maximum thickness of each compacted layer will be 6-inches and compacted to 95% of Standard Proctor at -1 to +3 percent of optimum moisture content per ASTM D698. Each lift shall be tested for moisture and density. The stockpiled topsoil will be spread on the outside bank. After the construction the lagoon, and all required pipe penetrations, the inside walls of the lagoon will be smooth rolled prior to the installation of the baseliner. The baseliner will be 60-mil thick HDPE synthetic liner. After the liner is installed, it will be tested for leaks prior to filling the lagoon with wastewater. There will be an outlet structure with a transfer pump (level control) that keeps the water level inside the digester at a constant level. The effluent will gravity flow through a 12-inch diameter digester outlet pipe to the level control wet well and be transferred by pump into the existing lagoon through a 6-inch diameter pipe. The transfer pump will be 10 HP GEA pump, designed for a flow of 560 gallons/minute, through 6-inch diameter, HDPE SDR 17 force -main to existing lagoon. Water will be transferred back to the existing lagoon at Hog Pack 1 Barns 1-3 by gravity flow through a 12-inch diameter gravity pipe from existing lagoon at Hog Pack 1 Barns 4-6.

The captured biogas will be treated to produce renewable natural gas (RNG) by a micro -gas cleaning skid (micro-GUS). Tail gas from micro-GUS will be vented to atmosphere, with levels documented in PAD letter. ROESLEIN.

Anerobic Digester- A sealed basin or tank designed contain the waste and capture the Biogas during anerobic digestion. Biogas- A product of Anerobic Digestion, produced by fermentation of organic materials. It typically has a composition of mainly methane and carbon dioxide, with traces of nitrogen, oxygen, hydrogen sulfide, and water. Digestate — liquid/solid digester effluent. Introduction The Project uses anerobic digestion of swine waste to produce biogas. The biogas is captured, upgraded to RNG, and combined with other swine site RNG before being ultimately injected into a utility's natural gas pipeline. The Project includes manure influent piping from the swine barns, an anerobic digester, biogas take -off pipe going to the Micro Gas Cleaning System (µGCS), and digestate transfer system to open storage lagoon. The barn waste stream contains two types of solids: organic and inorganic. A portion of the organic solids are broken down (digested) to produce biogas. The digestion of organic solids occurs as a result of several "types" of microbes, which exist in a symbiotic relationship. The naturally occurring microbes are one of nature's ways of breaking down organic material. The digester provides an ideal environment for the microbes to thrive. The inorganic solids either settle at the bottom of the digester or exit in the digestate stream as a dissolved solids or suspended solids. In addition to the information provided in the document, the operator should familiarize themselves with the local, state, and federal laws that may apply to operation of this site. Description of the Operational Components Below are listed the major component operations. Gravity Collection Pipe The gravity collection pipe receives waste from the hog barns and directs that waste to either an influent lift station or directly to the earthen lagoon digester. Typically, the diameter of the pipe is 8" (min) to 12 inches (max). The gravity collection pipe includes several clean -outs that provide access to the gravity collection pipe for removal of a clogs or blockage via use of a sewer snake or similar apparatus as needed. Typically, there will be at least one cleanout every 200 feet. During normal operation, the pipe should be free flowing, without obstructions, to transport waste to the lift pump station or directly to the anaerobic digester. Page 2 of 17 s1 ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS Register, NC RA270-22 Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 The barn operator is responsible for sending barn waste to the gravity collection pipe. The digester/biogas operator should check weekly, each hog barn waste outlet to ensure that there are no overflows, clogs, etc. Lift Pump Station (where necessary) The lift pump station receives wastewater from the gravity collection pipe and pumps that wastewater to the anaerobic digester via buried forced main. The waste enters the digester at the opposite end of the digester outlet. 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 float switches. 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 via 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 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, 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). In the event of a pipe clog or lift 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 a Lift Pump Station, the waste flows from the barns directly to the anaerobic digesters. Anaerobic Di eg ster The anaerobic lagoon is constructed outside of the 100-year flood plain and any wetlands. The treatment volume is designed utilizing a minimum volume of 50 cubic feet/head and with a minimum HRT of 40 days. The construction approach will be a cut and fill balance. The excavated material will be utilized to build the embankments. The berm fill material for the lagoon will be placed in 6-inch-thick lifts to a minimum of 95% of standard proctor at -1% to +3% of optimum moisture. Each lift fill be tested for moisture and density. The excavated material used for the lagoon berm construction will be free of sod, roots, and other objectionable materials. The minimum top width of the lagoon digester will be 15 feet with a minimum inside and outside slope of 3:1. After the construction of the embankment and after the installation of all pipes penetrating the berms, the inside of the lagoon will be smooth rolled and a 60-mil thick HDPE liner will be installed as the baseliner. Edges of the baseliner will be secured in an anchor trench at the top of the berm. Page 3 of 17 s1 ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS Register, NC RA270-22 Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 The anaerobic digester receives all raw waste 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, biogases (including methane, carbon dioxide, and hydrogen sulfide) are produced. These gases are captured under an impermeable cover (80-mil thick HDPE liner) and then directed to the biogas cleaning system. biogas blower or biogas dehydration system. Biogas captured and stored under the cover supplies the biogas draw off piping. All berm penetrations (gravity sewer, forced main, effluent to wet well, sludge removal piping must always remain submerged to create a liquid seal to prevent biogas from escaping. Perforated piping underneath the cover connects all sections of the lagoon to the draw off connection. The liquid waste is digested for a minimum of 40 days. The digester liquid effluent is either pumped or gravity fed to an existing storage lagoon. The lagoon digester cover should be supported by the lagoon liquid when not inflated. Dropping the lagoon liquid level too low may lead to an unsupported cover and possible cover stretching and cover damage. Recommended operation level is 3-4 ft below top of berm to ensure adequate digester biomethane production and ensure that the level does not exceed 2 ft below top of berm at any time during operational deviances. The digester liquid level should be monitored daily. Any settleable solids and microbes (i.e. "Sludge") build up slowly over months/years at the bottom of the digester. These solids can be periodically removed by connecting portable pipes and pumps to the sludge removal pipes in the digester and disposed of through permitted means on the farm or by a contract sludge hauler. There will be a total of eight 6-inch diameter sludge removal pipes installed near the bottom elevation the lagoon and terminated near the top of the berm. Four installed on each side of the central ballast pipe, staggered every other lateral. These pipes will be utilized for the periodic removal from the lagoon. Ballast piping on top of the cover control the cover inflation and direct rainwater to center rainwater trenches to be pumped to natural water shed (if uncontaminated). The cover should be free of excessive accumulation of rainwater and should not show signs of any damage or leaks. The effluent of the anaerobic digester flows from the anaerobic digester through an outlet structure and flows by gravity into the secondary lagoon. The outlet structure is equipped with a level gauge with 1-foot markings. The outlet structure has an overflow weir to keep a constant freeboard of 2' inside the lagoon digester. The effluent overflowing the weir will be directed to the secondary lagoon by gravity. During normal operation, the digester cover will inflate like a balloon from the biogas trapped beneath, an inflation guide can be found in Appendix A. Proper inflation of the digesters is critical to the reliable operation of the plant. A low level of inflation ensures that ingress of air doesn't occur into the biogas which would contaminate the gas with nitrogen and oxygen. 100% full inflation ensures that the covers are in an optimal state for 24-hour net heat gain by the digester and prepared for normal atmospheric wind conditions. The pressure under the cover will typically range from 0-0.3" w.c., a pressure of 0.4" w.c. can be dangerous. Page 4 of 17 y� Register, NC RA270-22 RO E S L E I N Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 ENGINEERS • MANUFACTURERS • CONSTRUCTORS Typical digester operation can be found in Appendix B. Mixing Pump A dry well will house a mixing pump which draws the water from the lagoon near the bottom elevation and discharges the water near the influent side of the digester. This pump will be operated on a regular interval. This pump is typically operated for approximately 4 hours a day, five days a week. Secondary Lagoon The effluent of the anaerobic digester flows from the anaerobic digester outlet pipe to the secondary lagoon. The secondary lagoon is used to store the treated effluent after anaerobic digestion until it can be land applied. There is an ammonia reduction unit installed on these secondary lagoons. The farm operator is responsible for the operation and maintenance of the secondary lagoons. Digestate liquid stored in the secondary lagoon is used for pit pre -charge and flush tank recharge. The secondary lagoon is a critical part of the integrated system, the Digester/Biogas 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 or pump. The outlet pipe from the anaerobic digester into the storage lagoon must remain submerged in the digester to provide a liquid seal and prevent biogas from escaping 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. Transfer Pump The transfer pump transfers accumulated effluent among available secondary lagoons as the farm owner desires to optimize effluent storage. The transfer pumps are manually operated through the local disconnect. Under normal circumstances, the transfer pump will only be used periodically by the farm owner. Typically, the transfer pump is used to draw down the digester liquid level in the fall to make room in the digester to store lagoon liquid during the colder winter months. Rainwater Cover Pump Two rainwater cover pumps are installed on end of the digester to remove accumulated rainwater from the digester cover. There will be a 3-inch suction line to each of these stormwater removal pumps. Erosion control measures, such as rip rap will be placed at the discharge point. Oxygen Injection System An oxygen injection system will be installed to limit the amount of hydrogen sulfide in the biogas. The oxygen injection system consists of an oxygen generation unit which produces 95% purity oxygen from air, and it will be injected under the cover at two locations. Calibrated Oxygen Page 5 of 17 s1 ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS Register, NC RA270-22 Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 monitoring instrument continuously monitors the concentration of oxygen in the head space under the cover. The maximum allowable oxygen concentration in the biogas will be 0.5%. Description of Anticipated Maintenance The system is designed to require as little maintenance as possible once it has been started up and is in operation. Sample tests should be performed periodically and to permitting requirements, to allow evaluation of the composition of the wastewater. System components should be visually inspected regularly and as recommended by the equipment manufacturer. If the system is well operated, it will display the following signs of being maintained properly: • All pipes should be intact and watertight. • The pumps should operate with little to no vibration and without excessive noise. • The anaerobic digester should be free of excessive accumulation of rainwater on the cover. The accumulated rainwater will be pumped off the cover via the Rainwater Pumps. The rainwater must be tested to determine the discharge location for the pumps. If contaminated the rainwater must be discharged back into the digester, otherwise it may be discharged safely on nearby vegetated areas. • The anaerobic digester cover should be free of any tears, punctures, or failures. • There should be no strong odors coming from the digester. • The secondary lagoon should be clean and free of floating debris. The liquid should be clean an clear. Routine System Maintenance Instructions For optimum operation and maximum efficiency maintenance should be performed daily. mechanical equipment should be cleaned weekly and lubricated as required. Equipment cleaning and lubrication should be done as specified in the O&M manuals provided by each equipment's manufacturer. Periodically, the sludge accumulated at the bottom of the digester will need to be removed, this will be done by following the existing Waste Utilization Plan (WUP). The sludge may be removed through the use of the sludge removal pipes utilizing a temporary pump. All application of the removed sludge should be done in accordance with the farms approved WUP & Nutrient Management Plan. Typically, a portion of sludge will be removed from the digester every other year. Sludge accumulation can be monitored by the site's operator through the use of inspections ports installed on the top of the digester cover and should be assessed annually. When assessing the sludge accumulation, the operator should aim to have as much biogas removed as possible prior to opening the inspection port to limit release of biogas into the atmosphere. Due to biogas production declining in cold weather, it is recommended to take sludge measurements during winter. To get a measurement of the sludge depth, the site operator will use the inspection ports and insert a pipe or gauge with graduated markings will be used to assess the depth of the sludge in the digester. When inserting the pipe or gauge caution should be used to avoid applying excessive pressure or even puncturing the liner of the digester. After sludge removal has been concluded, the operator should reconnect all fittings from the sludge removal pipes and piping as it was prior to the sludge removal.

The O&M manuals should provide instructions for possible field repairs or how to secure a piece of equipment until qualified repair personnel are able to arrive. Biogas Hazards Biogas and oxygen in air can potentially form a flammable mixture. Methane (CH4) is an odorless, flammable gas. CH4 is lighter than air and tends to rise and dissipate quickly outdoors. In addition to being primarily comprised of methane (55 — 60%), biogas is also comprised of carbon dioxide (35 — 40%), and trace amounts of hydrogen sulfide (H2S), nitrogen (< 2%), oxygen (< 1%), and water vapor (<8%) which are hazardous. Hydrogen Sulfide (H2S) has a distinct "rotten egg" odor at low concentrations. However, at higher concentrations, it overwhelms the sense of smell and cannot be detected. At concentrations > 1000 ppm, it can cause immediate unconsciousness and death through respiratory paralysis. Hydrogen Sulfide compositions in the biogas feed supply can be at 1500 to 2500 ppm/vol. Carbon Dioxide (CO2) is a colorless, odorless, tasteless, non -irritating, non -toxic gas. However, it can act as a simple asphyxiant by displacing oxygen present in air to levels below that required to support life. In environments with low concentrations of oxygen, confusion and reduced mental capacities can lead to poor judgement and increase the risk of safety events. Nitrogen (N2) gas is a colorless, odorless, tasteless, non -irritating, non -toxic, inert gas. However, it can act as a simple asphyxiant by displacing oxygen present in air to levels below that required to support life. In environments with low concentrations of oxygen, confusion and reduced mental capacities can lead to poor judgement and increase the risk of safety events. Equipment Supplies All equipment used around the digesters should be qualified to be used in Class Div2 areas. Proper Protective Equipment (PPE) All personel working around anerobic digesters should refer to local HSE officer for job specific PPE requirements and need. At a minimum, the following PPE should be used whenever in the vicinity of biogas. 0 4-gas personal monitor should be worn when in the vicinity of biogas o Safety glasses, safety shoes, gloves. o Personal Floatation Devices — when working on the cover.

Procedure No. Procedural Step Description Transfer Pump Operation 8.0.1 Transfer pumps transfer water from the covered lagoon digester to evaporative lagoons to maintain the desired liquid level in the digester. Lagoon digesters high level is limited to two (2) feet below top of berm (or freeboard). Lagoon digester low pump level is limited to one (1) foot above the sewer inlet pipe exit to maintain gas seal. All pipe -berm penetrations must remain sealed with liquid to avoid allowing biogas escaping through unsealed headers. The low pump level is — 9 ft below top of berm. The lagoon digester cover should be supported by the lagoon liquid when not inflated. Dropping the lagoon liquid level too low may lead to an unsupported cover and possible cover stretching and cover damage. Recommended operation level is 3-4 ft below top of berm to ensure adequate digester biomethane production and ensure that the level does not exceed 2 ft below top of berm at any time during operational deviances. The digester liquid level should be monitored daily. Transfer pumps can be operated manually or in timer mode. Normally, timer mode should be used as the pumps will not normally run continuously. During the biogas production season, the liquid level should be maintained at a higher level. As the production season slows down in the fall, Page 13 of 17 s1 ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS Register, NC RA270-22 Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 the digester liquid level should be pumped down slowly to low pump level. This will allow the maximum amount of manure to be stored during the off season and should be allowed to fill back up to high level, before starting the transfer pump and discharging liquid to evaporative lagoons. Digester Cover Operation 8.1.1 The digester covers are a fully welded system that is integral with the lagoon liners. Because of soil permeability, the 60-mil liner is utilized and fully welded to the 80-mil lagoon cover at the perimeter. All cover, liner, and anchor trench sheet material is HDPE which provides material toughness, flexibility, UV resistance, and water/gas impermeability. The cover uses 6" grout filled HDPE piping at both the laterals and center anchor trench. The Laterals are spaced on the order of 42-44 ft apart along the entire length of the cover and are used to restrain gas movement from one side of the cover to the other and avoid fast movement of the cover. Laterals are only effective when they are substantially laying on the digester water operating level. The center trench is comprised of two parallel pipes that run the center axis along the length. The center trench is used to both restrain the cover upward movement and to provide an area in which incident rainwater collects for easier pumping. An 8" corrugated perimeter biogas collection header is installed around the entire circumference of the digester cover to ensure generally equal gas inflation around the perimeter during low gas production and low cover inflation. The digester cover is a volumetric storage vessel, not a pressure vessel. The cover is designed to contain the biogas emanating from the digester surface for collection into the perimeter biogas header. The pressure under the cover operates at 0.0" w.c. (Water column) to approximately 0.3" w.c. Pressure is not measured as it is immaterial to operations. In the event of power outage or emergency, there are two (2) 6" flanged emergency vent ports directly on the cover, opposite of the swine barns. These ports have lug butterfly valves and should be used with proper venting apparatus to ensure that the biogas is vented at an elevation high enough to support safe operator opening and closure of the valves. Proper inflation of the digesters is critical to the reliable operation of the plant. A low level of inflation ensures that ingress of air doesn't occur into the biogas which would contaminate the gas with nitrogen and oxygen. 100% full inflation ensures that the covers are in an optimal state for 24-hour net heat gain by the digester and prepared for normal atmospheric wind conditions. This site has an annual hurricane season which will involve strong storms and large amounts of rain. The direction below, addresses normal, winter season, and hurricane season that are predicted. It is ultimately important to continually monitor weather forecasts at least 5 days out and make any adjustments in cover inflation in advance. Page 14 of 17 s1 ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS Register, NC RA270-22 Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 The operations group should keep in mind the following items that affect the performance of the cover. • Laterals and center anchor trench piping is designed to control the movement of the cover in all wind conditions. The grid of piping reinforces the cover in both directions and also acts as a labyrinth in which gas has to pass when moving during wind conditions, thus slowing the gas velocity and cover movement. • More cover contact with the water allows the cover to survive high wind conditions due to the fact that water surface tension anchors the cover and there is less volume of gas to move around the cover. Taut cover material also allows the cover to withstand higher wind conditions. • Less cover rise above the top of berm reduces the area of cover that wind exerts force on. Less cover rise around the perimeter also reduces the cover profile which in turn reduces the Bernoulli lifting mechanism on the cover in high wind conditions (similar to a plane wing profile) • HDPE has a relatively large coefficient of thermal expansion. The cover will be much hotter during the day with sunlight exposure than at nighttime. Also, radiant heat loss at night will condense water in the biogas space under the cover, also reducing the total volume of gas under the cover. Methane, Carbon Dioxide, and Hydrogen Sulfide do not condense but do decrease in volume as an ideal gas. The volumetric difference in gas over a 24-hour period day to night is due to the molar water volume in the biogas and biogas temperature under the cover. The cover and laterals are designed for expansion and contraction over all biogas ambient dry bulb temperatures between high and low pump digester levels. • As the perimeter of the digester is inflated less, less water will run off the cover around the perimeter. This is beneficial to reduce the possibility of erosion of the digester berms. Covers are easily pumped off with the Mixing Pumps to a location several hundred feet from the berm. The following digester cover operating guidance should be followed by plant operations group: 1. In all operating conditions, the center rain trench piping shall be fully, 100%, laying on the digester water surface. 2. In all operating conditions, the laterals shall be at minimum, substantially laying on the digester water surface. Per operating modes below, maximum 15' of lateral at either end shall be suspended above the surface of the cover. 3. Digesters will produce gas at different rates. The blowers and A2000 piping is designed to transfer gas between covers to maintain cover inflations within the cover operating modes below while conserving biogas. 4. Anemometers are installed on the plant and accessible through Ignition. Each Anemometer indicates wind speed up to 90mph and wind direction. Data is recorded in the historian. Operators will monitor wind speed and use as Page 15 of 17 s1 ROESLEIN ENGINEERS • MANUFACTURERS • CONSTRUCTORS Register, NC RA270-22 Anaerobic Digester O&M Revision: 0 Effective Date: 4/15/2024 necessary to refine operations compared with predicted winds at remote towns based on the actual farm surrounding geography. 5. With A3000 fully operational, there is no reason to inventory biogas under the covers beyond the operating modes detailed below. Operating Modes: 1. Normal Operation: a. Cover inflation around the perimeter is no higher than 6' above top of berm. Inflation will generally vary between 3' to 6' based on wind speed and direction. b. Laterals are substantially on the digester water surface with end 10-15' suspended and end cap at —2' off of liquid surface. c. Gas cover between laterals is pillowed at nominal 2-4' above water surface at peaks between the laterals. d. Cover is tensioned but not tight. The cover will incrementally move in the wind but with gentle local rolling effect. e. This mode is applicable for winds sustained and gusts up to 50 mph from all directions. 2. Winter Season Operation: a. Cover inflation around the perimeter is no higher than 6' above top of berm. Inflation will be generally 3' to 5' based on wind speed and direction. b. Laterals are fully on the digester water surface, including end cap. c. Gas cover between laterals is not pillowed and flat on the water with the exception of naturally occurring and sporadic cover rolls/channels. d. Cover is tensioned but not tight. The cover will incrementally move in the wind but with gentle local rolling effect. e. This mode is applicable for winds sustained and gusts up to 65 mph from all directions. 3. Hurricane / High Wind / Intense Storm Predicted: a. Cover inflation around the perimeter is no higher than 3' above top of berm. Nominal inflation above top of berm is 1.5' to 2'. b. Laterals are fully on the digester water surface, including end cap. c. Gas cover between laterals is not pillowed and flat on the water with the exception of naturally occurring and sporadic cover rolls/channels. d. Cover is tensioned but not tight. The cover will incrementally move in the wind but with local rolling effect. e. Cover will be flat extending from the ends of the laterals towards the anchor trench for at least 20'. f. This mode is applicable for winds sustained and gusts above 65 mph from all directions. If winds are expected to exceed 75 mph, the blowers (preferentially) and or emergency vents (if required) should be used to evacuate substantially all gas.

Work with the farm to adjust timers if required to bring the level back into target range. • Visually inspect the digester cover and quantify inflation level and laterals position. • Visually inspect and quantify area of digester cover occupied by water. Utilize pumping systems to remove surface water from the center anchor trench. Weekly Checks 8.3.1 Walk perimeter of digester checking for: • Leaks via a gas monitor or methane detection device around the base of the cover and the anchor trench. Use of soapy water from an orchard sprayer may also be used to detect leaks during cool cover conditions and still wind. • Torn ballast straps or laterals that are not aligned straight. • Settling or erosion around berm • Any running equipment for an uncharacteristic operating state (noise/vibration) • Sample cover rainwater to determine if it is "hot" aka contains dissolved ammonia because contaminated cover water is an indication of a possible digester cover leak and will need to be pumped under the cover. • Trash and foreign matter on the cover can cause problems with normal operation. If debris becomes wedged between the ballast weight and cover it is possible for punctures to occur. Additionally, foreign matter can cause the rain collection channels to become blocked and disrupt flow of the rainwater. All operators and contractors working on top of the digester should be cognizant of the perimeter rock and make sure not to kick the rock into the digester. Furthermore, a yearly pre -season inspection should occur to inspect for and remove any debris along the entire length of ballasts.

INTRODUCTION Several safety hazards exist when converting manure and organic residuals (non -farm feedstock) into energy using anaerobic digestion (AD) technology. These hazards can cause serious bodily harm and in some circumstances, can be fatal. Common hazards I Figure 1: Safety signage on AD feed system associated with AD systems include drowning, electric shock, and noise exposure. However, biogas and its constituents, many of which are colorless and odorless, can unknowingly expose operators and visitors to hazards such as asphyxiation and burns due the flammable nature of methane. Workers must take proper precautions when handling and storing organic material and managing the production of electricity and combustible gases. The purpose of this document is to identify the major hazards associated with an AD facility and outline basic practices that will help maintain a safe and successful working environment. The intended audience for this guide is owners and operators, and the guide is not intended to replace safety training or instruction, but rather enhance it. 2.0 SAFETY HAZARDS FOR ANAEROBIC DIGESTION The following sections identify major hazards that can exist with an AD facility. These include: • General safety precautions • Hazards associated with biogas • Confined space entry • Electrical system hazards Figure 1 shows a feed hopper for an anaerobic digester with a dozen warning signs, including fall, entanglement, and explosion potential. 1 Safety Practices for On -Farm Anaerobic Digestion Systems 2.1 GENERAL SAFETY PRECAUTIONS The following sections describe general safety concerns associated with AD facilities. 2.1.1 Drowning Liquid tanks and ponds for storage pose a drowning threat. Whenever a drowning potential exists, ring buoys, ropes, or ladders should be readily available for rescue purposes (Occupational Safety and Health Administration [OSHA], 2002). The drowning risk is highest when employees are servicing equipment located in digester or storage tanks. Accidental drowning can occur when people unfamiliar with the farm and manure handling system mistakenly enter storage structures. Slipping on a synthetic liner or walking on crusted manure storage are examples of situations that can lead to accidental drowning. OSHA suggests posting signs similar to the one shown in Figure 2 and erecting fences around manure storage structures to reduce the potential of an individual or animal unknowingly entering one. Figure 2: Manure storage warning sign in English and Spanish LIQUID MANURE STORAGE ALMACEMAJ E DE ETIt-ROL 00U.111120 Jrs_ If an individual is drowning, the first step should be to call 911, followed by a rescue attempt using a life preserver, rope, or ladder. The presence of biogas—an asphyxiant that can cause a person to pass out —can increase the potential of manure storage drowning. (Biogas hazards are discussed in greater detail in Section 2.3.) Individuals attempting to rescue a drowning individual should never enter a manure storage structure because they could also be overcome by the poor air quality. 2.1.2 Fall protection Serious injuries can result from falls of any distance. When possible, employees should perform maintenance work from the ground. At most AD facilities, however, multiple elevated locations are present. For example, equipment on the top of aboveground AD tanks are 10 to 25 feet off the ground. According to the OSHA general industry standard any "time a worker is at a height of four feet or more, the worker is at risk and needs to be protected" (OSHA, 2008A). Fall protection, such as guardrails, a safety harness (also discussed in Section 2.2.4), and self - retracting lifelines, should be used when an employee is above the 4-foot threshold (API, 2006). The enclosed fixed ladder and guardrail system on the feedstock storage tank shown in Figure 3 complies with OSHA fall protection standards. Safety Practices for On -Farm Anaerobic Digestion Systems Another common example of a fall risk is shown in Figure 4, where a ladder is leaned against a feedstock storage tank. The two concerns with the situation presented in Figure 4 are: (1) the tank height is approximately 10 feet and (2) there are no securing devices or slip resistant feet on the ladder, nor is there a rope to secure the top. When ladders are used to access elevated equipment, they should be secured and supervised at all times. Once the ladder is no longer needed, it should be removed. 2.1.3 Burns Throughout an AD facility, pipes containing hot fluids or exhaust gas can pose potential burn hazards. Other potential sources of burns are heat exchangers, boilers, pumps, or engine generators, where temperatures can exceed 160°F. Simply rubbing up against a heat exchanger or accidently placing a hand on a hot pipe can result in serious burns. All Figure 3: Permanent ladder and guardrail on feedstock storage tank employees and visitors to the AD facility should be cautioned not to touch any equipment or pipelines. When possible, hot surfaces should be identified as burn hazards, and all pipes should be clearly labeled to indicate the contents, Figure 4: Ladder leaning on feedstock storage tank flow direction, temperature, and pressure. Insulation should be used to encase the pipe and reduce the potential for accidental burns. Figures 5 and 6 provide examples of pipeline insulation and labeling. 2.1.4 Entanglement hazard Pumps, augers, impeller mixers, chains, drive shafts, and other machinery pose entanglement hazards due to pinch points and other moving parts. In most AD systems, the primary exposure to entanglement is the unguarded driveshaft 3 Safety Practices for On -Farm Anaerobic Digestion Systems of a pump. To reduce the entanglement risk, all equipment safety guards should be in place and individuals should tie back long hair and avoid wearing loose -fitting clothing and jewelry. 2.1.5 Feedstock and digestate spills Figure 5: Insulated and labeled hot water pipes Feedstock (any organic material entering the eYi URN digester) and digestate (any material exiting E the digester) should be carefully transferred and contained. In the event of a major ` I feedstock or digestate spill, workers should exercise caution when containing the f -- material. The first step should be to control pp�� the source causing the spill. Once this is'55'°`U° achieved, workers should contain the spill by V constructing temporary containment structures around the affected area. Excavation equipment such as bulldozers and backhoes should be readily available for this purpose. Isolating the spill reduces potential damage to nearby buildings and contamination of surface Figure 6: Biogas pipeline indicating waters and sensitive areas. After containing the temperature and flow direction spill, the facility should notify the proper authorities (as defined by state -specific permits), to comply with all applicable local, state, and federal regulations. For non -farm feedstocks, such as food waste, the spill -reporting agency should be clearly identified on all records related to the material, including material safety data sheets (MSDS) and manifest logs indicating the date, quantity, and material (feedstock) brought onto the farm. The final step in spill response is site cleanup and restoration. 2.1.6 Mechanical failures In the event of a mechanical failure, workers should reference the vendor manuals to troubleshoot the issue. Vendor manuals for mechanical machinery should be organized and included in the emergency action plan, which is discussed in Section 3.1. Only trained staff 4 Safety Practices for On -Farm Anaerobic Digestion Systems should be permitted to repair digester equipment. Operators should use lockout/tagout procedures (see Section 2.1.7) during all mechanical equipment repairs. To avoid mechanical failures, the system operator, with support from the technology provider, should develop a preventative maintenance manual for the site. 2.1.7 Lockout/ragout According to OSHA standard 29 CFR 1910.147, lockout/tagout refers to the specific "practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities" (OSHA, 2007A). Simply stated, before an employee services a piece of electrical equipment, the power supply should be turned off and the employee should place a padlock on the power supply. The padlock serves to prevent someone else from accidently re -energizing the equipment being serviced. The lock should have a tag on it identifying the individual who locked out the Figure 7: Electrical panel turned off and locked out equipment. In Figure 7, one of the four electrical breakers shown is turned off (disengaged) and locked out. Once a piece of equipment has been locked out, the only individual with the authority to unlock that piece of equipment is the person who initially locked it out. Employees should follow this practice every time they service any electrical or electrically powered equipment. OSHA estimates that compliance with lockout/tagout procedures prevents an estimated 120 fatalities and 50,000 injuries each year in the United States (2007A). 2.1.8 Ignition sources Biogas generated during anaerobic digestion is flammable. Over the past couple of years, several AD systems have been damaged or destroyed by fires fueled with biogas. While no specific setbacks or standards have been established for biogas, facilities should observe standards for similar systems. The National Fire Protection Association (NFPA) has established a range of setback distances for liquid propane (LP) fuel based on storage capacity (2009). For LP gas, the setback ranges from 10 feet for small storage devices (<500 gal water capacity) to 100 feet for large storage systems (>70,000 gal water capacity). Safety Practices for On -Farm Anaerobic Digestion Systems Smoking and open flames should be prohibited in the general vicinity of the digester and a setback distance of 25 to 50 feet is suggested for all possible ignition sources to reduce the potential for fire or explosion. Ignition sources can include (but are not limited to) light switches, electric motors, pilot flames, and cell phones. Facilities should designate smoking areas at least 50 feet from the digester system to ensure that visitors and employees do not inadvertently create an ignition source. Signs, like the one shown in Figure 8, should also be used to warn all individuals of the explosion or fire risk associated with AD systems. The National Electric Code (NEC, 2005) dictates that electrical wiring near combustible gas must conform with the Class 1, Division 1 hazardous location standard. Biogas is combustible, so the Figure 8: Explosion potential sign hazardous location standard should be applied to AD systems' electrical wiring. For repairs requiring open flames or electric spark, ventilation should be provided such that methane levels are maintained below a safe level, as discussed in Section 2.3.3. Figure 9: Gen set enclosure with hearing protection warning sign 2.1.9 Noise levels Exposure to high levels of noise can result in discomfort or short-term hearing loss. In extreme cases, or if the noise exposure occurs over a long period of time, permanent hearing loss can occur. The main source of high noise levels is the engine generator set (gen set). Actual decibel (dB) levels produced at an AD facility will differ due to varying acoustical settings, but a gen set can produce between 100 —140 dB (Fenton, 2011). The facility is required to supply noise protection devices, such N. Safety Practices for On -Farm Anaerobic Digestion Systems as earplugs, to employees and visitors who are exposed to high noise levels (OSHA, 200813) (See Table 1). Handheld decibel meters are widely available and provide an inexpensive method to quickly determine the noise level. Also, OSHA encourages posting signs indicating "hearing protection is required in this area." (See Figure 9). Table 1: Safe maximum allowable decibel level (OSHA, 2008B) Duration per day (hours) Sound level (dB) (as measured with a sound level meter set on slow response 8 90 6 92 4 95 3 97 2 100 1.5 102 1 105 0.5 110 0.25 115 2.2 CONFINED SPACE ENTRY Constituents of biogas, including carbon dioxide, methane, and hydrogen sulfide, present the potential for both asphyxiation and fire or explosion in confined spaces. It is important to remember that even a few gallons of manure or other organic material in a tank or confined space can pose a serious health risk under Figure 10: Basic confined space warning sign the right conditions. A recent example of confined space entry fatality occurred in July of 2010 when two farm employees died while cleaning a storage tank similar to the one shown in Figure 4 (Michigan Department of Energy, Labor and Economic Growth [MEDLEG]). Signs should be used to alert employees and visitors when confined space entry risks exist. Figure 10 shows an example of a standard confined space warning sign. The following background PELIGR "Elm: CONFINED SPACE ESPACIO LIMATADO information and guidelines are intended to promote a safe working environment when confined space is involved. 7 Safety Practices for On -Farm Anaerobic Digestion Systems 2.2.1 Definition "Confined space" is defined by OSHA as "having a limited or restricted means of entry or exit; large enough to bodily enter and perform tasks; and lastly, not designed for continuous occupancy." Currently, state -by -state standards vary for permit -required confined spaces training for agriculture; however, confined spaces are widely recognized as a common hazard. Confined spaces include, but are not limited to, tanks, pits, silos, underground vaults, storage bins, and manholes (MDELEG, 2010). 2.2.2 Confined space training, certification, and rescue plan Employees associated with AD systems or who manage organic residuals MUST be trained in confined space entry to maintain a safe working environment (Gould, 2010). Several cases have resulted in fatalities due to a lack of understanding of the hazards associated with confined spaces. As discussed earlier, two farm employees died when they were overcome by a lack of oxygen while cleaning a feedstock storage tank (MDELEG, 2010). The employees were power washing a tank that contained only 6 to 8 inches of molasses residue, which had sat unused for five to six months. By conducting basic employee education and strictly adhering to OSHA confined space entry guidelines, facilities can provide a safe working environment for farm employees. Currently, OSHA does not require farms to offer specific training for confined space entry; however, it is the employer's responsibility to educate employees in order to maintain a safe working environment. When entering a confined space, the "buddy system" should be used, in which any person entering a confined space is monitored from a safe distance by a second person. The employee entering the confined space must wear a harness attached to a retraction device that the second employee can activate to pull the individual to safety in an emergency. The facility should develop a rescue plan for emergency confined space entry situations. This plan should describe the use of the safety Figure 11: Handheld multi -gas detectors a pq Images fro m Goo gle images equipment in emergency situations, the actions to be taken, and the personnel responsible for each action. The plan may also include training and certification information. RI Safety Practices for On -Farm Anaerobic Digestion Systems 2.2.3 Inspect atmosphere prior to entry Before entering a confined space, a worker must test the atmosphere inside the space, as required by OSHA general industry standard 1910.146 (1998). The person can perform this testing using a handheld multi -gas detector capable of detecting oxygen, carbon monoxide, hydrogen sulfide, and lower explosive limits (LEL) levels. Several models of multi -gas detectors are shown in Figure 11. When testing the atmosphere within a confined space, the employee should remain outside in a safe location. Many multi -gas detectors are equipped with an extension hose for this purpose. In compliance with standards (OSHA, 1998), the employee should test for the following: Oxygen level: above 19.5 percent by volume air 2. Methane: below 5 percent by volume of air 3. Hydrogen sulfide level: below 20 parts per million (ppm) If any of the above conditions are not met, the atmosphere is deemed hazardous and should not be entered by any personnel until forced ventilation has eliminated the hazardous conditions. During entry, continuous ventilation with an explosion -proof blower will ensure that fresh air is displacing any hazardous air that may be trapped in the confined space. Workers must maintain and calibrate this equipment according to the manufacturer's recommendation in order to effectively monitor atmospheric conditions. 2.2.4 Safety equipment When entering a confined space, an employee should wear a safety harness attached to a winch or pulley outside of the pit. Examples of safety harnesses and a winch are shown in Figure 12. This safety precaution, allows a coworker to assist a trapped employee without having to enter the space in the event of an emergency. A self-contained breathing apparatus (SCBA) should be used only in emergency situations. Figure 12: Safety harnesses, ropes, and a chain fall at an AD facility Safety Practices for On -Farm Anaerobic Digestion Systems Figure 13 shows a basic backpack -style SCBA with fitted facemask. Any employee using a SCBA must be properly trained and fitted for using the equipment. For an individual to become certified in confined space entry, they should consult the State approved OSHA administration. 2.3 HAZARDS ASSOCIATED WITH BIOGAS AD biogas is composed of three main constituents: methane, hydrogen sulfide, and carbon dioxide. Each of these gases can be dangerous under certain circumstances. Common hazards associated with biogas include asphyxiation and fire or explosion potential. Overall, it is always a good idea to test the atmosphere when biogas may be present as well as maintain proper ventilation. Workers can use a handheld multi -gas detector, similar to one of those shown in Figure 11, to determine if hazardous levels of biogas are present. Low-cost detectors will simply identify dangerous level of biogas, while higher end detectors can report specific concentrations of the primary biogas components. 2.3.1 Asphyxiants Gases that prevent the uptake of oxygen into human cells Figure 13: Self-contained breathing apparatus Irnage fro rnhttlX;' ,-r::::.enriSUPPI .corn/ are referred to as asphyxiants. There are two categories of asphyxiants: simple and chemical. A simple asphyxiant displaces oxygen, and chemical asphyxiants "reduce the body's ability to absorb, transport, or utilize inhaled oxygen. Asphyxiants are often active at very low concentrations (a few ppm)" (Lawrence Berkeley National Laboratory, 2008). Asphyxiant gases are present wherever there is storage of an organic material; therefore, manure pits or any other areas for organic material storage become potentially dangerous. Following are the various asphyxiants that are typical constituents of biogas. • Simple asphyxiants —carbon dioxide and methane • Chemical asphyxiants — ammonia and hydrogen sulfide 10 Safety Practices for On -Farm Anaerobic Digestion Systems 2.3.2 Immediately dangerous to life and health Within confined spaces and other covered areas, the potential exists for atmospheric concentrations to develop that become immediately dangerous to life and health (IDLH). An IDLH condition can be defined as an atmospheric concentration of any toxic, corrosive, or asphyxiant substance (simple or chemical) that "poses an immediate threat to life or would cause irreversible or delayed adverse health effects or would interfere with an individual's ability to escape from a dangerous atmosphere" (OSHA, 2008C). Following are the main IDLH concerns when handling the production of biogas (Center for Disease Control and Prevention, 1995). • Oxygen deficiency — less than 19.5 percent by volume air • Hydrogen sulfide — more than 100 ppm • Ammonia — more than 300 ppm • Carbon dioxide — more than 40,000 ppm Signs similar to the one shown in Figure 14 should be used to alert employees and visitors of the potential for IDLH conditions. Areas prone to these conditions include structures housing the gen set or boiler, below grade pump chambers, and biogas storage devices. Figure 14: Sign indicating IDLH potential DEADLY MANURE GASES POSSIBLE DEATH MAY BE IMMEDIATE! ENTER PITONLY WITH: • SELF-CONTAINED AIR SUPPLY • VENTILATION • RESCUE HARNESS, MECHANICAL LIFT, STAND-BY PERSON A simple and convenient way to ensure the safety of an area's atmosphere is by installing a wall -mounted sensor that can detect hazardous gases (e.g., methane, LEL, hydrogen sulfide, carbon monoxide). In the event that a hazardous gas sensor is triggered, the emergency action plan (see Section 3) should be implemented. 2.3.3 Explosion potential Methane, the main component of biogas, is flammable when it mixes with air. Upper and lower explosive limits (LEL) are established to provide an identifiable range of concentrations that will produce a flash fire when an ignition source is presented. The LEL is often referred to as a flammable limit. For methane, the lower and upper explosive limit is 5 percent and 15 percent by volume of air, respectively (Linde Gas LLC, 1995). Figure 1S: Safety signs posted at AD facility 11 Safety Practices for On -Farm Anaerobic Digestion Systems 2.4 ELECTRICAL SYSTEM HAZARDS The generation of large quantities of electricity at an AD facility creates electrical hazards, most of which can be found near the gen set, transformer, and electrical panels. The only personnel with the authority to service and repair electrical systems are licensed electricians. In addition, the facility should post signs identifying general electrical hazards near the electrical generation system (see Figure 15 for an example of basic signage). 2.4.1 High voltage Any electrical source above 600 volts is considered high voltage (NEC, 2005). Typically, transmission lines from the transformer are the source of the highest voltage on a farm. A transformer is a piece of machinery used to increase the voltage, allowing for more efficient transport of the electricity. When dealing with such high voltage, the main hazard is contact with exposed leads, which could be fatal. Figure 16 shows exposed lead transformers commonly used on utility poles. Ground -mounted transformers used on farms and at AD facilities are typically enclosed like the one shown in Figure 16: Standard electrical transformer with exposed leads Figure 17. Enclosed transformers should remain sealed Figure 17: Enclosed electrical and locked at all times, and only a licensed electrician transformer should perform transformer maintenance. V; 2.4.2 Low voltage All electrical sources less than 600 volts are considered -----E n low voltage (NEC, 2005). Typically, switches, - controllers, fuses, breakers, wall outlets, and electrical panels are considered low -voltage devices. One major hazard associated with electrical panels is arcing, which " occurs when electricity from an energized source jumps a gap of air and discharges into an adjacent conductive surface, typically metal. If an individual happens to be in the pathway of the arc, they can be seriously burned or killed. Cover plates are used to contain arcing by shielding the employee from any potential harm. Therefore, the facility should ensure that the proper cover plates are intact and correctly in place on the panel or outlet. 12 Safety Practices for On -Farm Anaerobic Digestion Systems 2.4.3 Electrical fires In the event of an electrical fire, the person fighting the fire should use an ABC classified multi- purpose fire extinguisher rather than a water -based fire extinguisher, which could result in electrocution. If possible, the electricity should be shut off to the facility before fighting the fire. The facility should train operators to identify the difference between electrical fires and ordinary combustible fires (Wallenwine, 2011). 3.0 MAINTAINING A SAFE WORKING ENVIRONMENT AD facilities can provide a safe working environment, as long as proper safety measures are taken. The following sections present recommended steps for maintaining a safe working environment at AD facilities, adapted from the self -assessment guide prepared by Nellie Brown (2007), titled "Conducting a Safety Walk-through on a Farm: Hazards of the Manure Handling System, Anaerobic Digester, and Biogas Handling System" and the emergency action plan requirements of the National Pollution Discharge Elimination System (NPDES) program. 3.1 EMERGENCY ACTION PLAN In most states, AD facilities are required to have emergency action plans (EAP) as part of their NPDES permits. A major objective of an EAP is to develop response protocols to specific emergencies so that if an accident occurs the facility will conduct the appropriate actions in the correct sequence. As a general recommendation, each situation should be broken down into the following components. Assess the extent of damage in the following order: a. Human health b. Environmental health C. Mechanical integrity 2. Correct the problem immediately if possible. 3. Contact the appropriate agencies and personnel to resolve the problem. The contents of an EAP should be well organized in a binder or an electronic file and distributed to all employees so that they are informed of the proper safety protocols. The facility should provide local emergency departments with a copy of the EAP and invite them for a tour of the operation so they can become familiar with the facility. Also, the facility should post a copy in a highly visible area where visitors enter the facility. 13 Safety Practices for On -Farm Anaerobic Digestion Systems To maintain an effective EAP, the facility should perform an annual review of the document to keep it up to date. Conducting annual training sessions will ensure that employees have a basic understanding of the EAP. The following sections present the recommended content to be included in an EAP. 3.1.1 Directions to AD facility Often, the AD facility is not clearly visible from the main road, especially if it is located in an agricultural setting. Therefore, detailed driving directions from the closest major road, intersection, or town to the physical location of the AD facility should be included in the EAP. 3.1.2 Contact information The EAP should provide a list of emergency and non -emergency contacts, including the job title and cell phone number of each person. Recommended contacts are: • Farm or AD owner • AD operators • Emergency and nonemergency responders o Fire department o Poison control o Law enforcement o Hospital • Electric and gas utilities • Contractors o Electrical o Excavation o Mechanical • State health and safety officials Contact information should identify the appropriate after-hours emergency contact information as well. The contact list should be posted in multiple locations throughout the AD facility and farm so that in the event of an emergency, there is quick and easy access to this information. It is important that the contact list be updated routinely to make sure all information is current. 14 Safety Practices for On -Farm Anaerobic Digestion Systems In many rural locations, calling 911 may not be the best method for reaching emergency responders. On an annual basis, the AD operator or owner should host a site tour with the local fire, ambulance, and sheriff departments. The purpose of this tour would be to familiarize emergency responders with the site and system, as well as identify the most direct contact method in the event of an emergency. 3.1.3 Site map The EAP should include a detailed site map that identifies and labels relevant structures and major equipment (e.g., flare, gen set, boiler) at the AD facility, as well as the location of emergency equipment. It should also clearly identify the locations of biogas supply shutoff valves and the primary electrical disconnect and control panel. 3.1.4 State and local health and safety requirements The EAP should include the federal and state health and safety regulations for the facility, as well as all OSHA documents, guidelines, and certifications, including confined space entry training documents. In addition, MSDS for non -farm feedstock and any chemical or biological additives should be included in the EAP and posted at the facility so that employees can have quick access to the information. 3.1.5 Equipment vendor manuals The EAP should include the vendor manuals for all equipment at the AD facility. These materials should be well organized so that in the case of a mechanical failure, an operator can locate and reference a specific vendor manual quickly and easily. 3.2 SAFETY AND EMERGENCY EQUIPMENT The following sections list recommended supplies and equipment an AD facility should have available for normal daily operation or in the event of an emergency. The list is divided into supplies and equipment to be maintained on site, so employees can access it within minutes, and equipment that should be locally available and could be delivered to the site within a few hours. A logbook of equipment inspections and expiration dates and the equipment manuals should be located with the safety equipment. 3.2.1 Anaerobic digester facility (onsite) • Personal protective equipment o Gloves o Safety glasses 15 Safety Practices for On -Farm Anaerobic Digestion Systems o Hearing protection o SCBA (provided employees are properly trained and fitted for using the equipment). • First aid kit • Fire extinguishers (ABC) • Explosion -proof instruments (e.g., flashlight, ventilation blower, hand tools) • Rigging equipment for rescue of a person o Hoist, winch, or pulley o Safety harness • Multi -gas detector with extension hose • Ring buoy • Shovel 3.2.2 Locally (able to be onsite within a few hours) • Excavation equipment (e.g., bull dozer, backhoe, excavator) • SCBA and trained individual 3.2.3 Baseline environmental conditions During startup and for the first 6 to 12 months of use, operators should collect operational parameters and air quality measurements around the AD facility on a weekly basis to establish baseline/normal operating conditions. Basic operational parameters should include pressure and temperature readings on pipelines where gauges are installed. Using a handheld multi -gas meter, employees should check the air quality inside all structures or rooms, along with the conditions in below -grade pump chambers, near the base of digester tanks, and along biogas pipelines. At a minimum, the concentration levels of hydrogen sulfide, carbon monoxide, and methane should be measured and recorded. By establishing baseline operating conditions, the AD operator has a point of reference for troubleshooting operational problems and determining when hazardous conditions are developing or already exist. 16 Safety Practices for On -Farm Anaerobic Digestion Systems 3.3 ELECTRICAL The following section provides common practices to help maintain safety by reducing the potential for electrical hazards that may occur at an AD facility. 3.3.1 Daily inspections The AD facility should instruct operators to perform daily inspections of the electrical system. This inspection should include, but not be limited to, the following: • Conduit connections to panels • Panel cover integrity • Conduit integrity • Exposed and damaged wires • Corrosion of wires • Signs of electrical overheating If there is any sign of the aforementioned problems, operators should contact the site manager or a licensed electrician to resolve the issue. Figure 18 shows a corroded electrical control panel that an Figure 18: Corrosion on an electrical control panel operator should identify for repair during daily inspections. The operator should not attempt to fix the problem unless he or she is the appointed licensed electrician for the facility. 3.3.2 Switches, controllers, fuses, and breaker panels Electrical panels should not be obstructed by any object that would impede the accessibility of the panel itself. For example, temporarily placing a 55-gallon drum below a circuit breaker or installing a pump below a control panel would impede accessibility. Moreover, electrical panels should always be visible so that emergency responders can locate them easily. This becomes imperative when an electrician unfamiliar with the facility needs to turn off the power quickly in an emergency situation. All electrical panels should be well labeled and include an accurate, up-to-date copy of the wiring diagram (Wallenwine, 2011). Additional copies of the wiring diagram should be maintained off site and digitally in the event that a copy is lost, damaged, or destroyed. The facility should check the local electrical code to determine the clearance required around the electrical panel. 17 Safety Practices for On -Farm Anaerobic Digestion Systems 3.3.3 Roles of operators An operator inspects and observes any defective electrical problems but does not perform any electrical maintenance. A licensed electrical engineer appointed by the AD facility is responsible for maintenance and repair of electrical problems. 3.3.4 Visitors on site Unattended facilities associated with the AD system should be locked to limit risk to individuals unfamiliar with the surroundings and to ensure that the system continues to operate efficiently. Employees familiar with the AD system should escort visitors at all times. Visitors to an AD facility are not to operate any switches, controllers, or other electrical functions, including light switches. 3.4 PERSONAL PROTECTIVE EQUIPMENT Personnel at an AD facility should be provided with proper -fitting personal protective equipment (PPE). The employer is responsible for communicating and educating the employees on the proper use of PPE (OSHA, 20076). At a minimum, OSHA recommends protective gloves, splash -proof goggles, hearing protection, and steel toe shoes for employees associated with the digester system. For visitors to the facility, safety glasses and hearing protection should be available and worn while on site. 3.5 ACCIDENT PREVENTION SIGNS AND TAGS Accident prevention signs and tags should be visible at all times when work is being performed where a hazard may be present and should be removed or covered promptly when the hazards no longer exist. Also, caution signs should be designed to be understood by non-English speakers. The EAP should include resources documenting where proper signs or tags can be obtained for potential facility hazards. A variety of OSHA -approved accident prevention signs are shown in Figure 19. Figure 19: OSHA accident prevention signs i i R AUTHORIZED Mrice aarrr KEEP HANDS NO SMOKING EYE PROTECTION REQUIRED D0HHaoE CLEAR OP N FLAMES NONO PERSONNEL ONLY PERSONNEL ONLY SPARKS 18 Safety Practices for On -Farm Anaerobic Digestion Systems 3.6 PERSONNEL TRAINING REQUIREMENTS Annually, the facility should review the EAP with all employees associated with the AD system and new hires should go through safety and system operation training before being permitted to work at the AD facility. In addition, owners of systems should be aware of OSHA requirements and comply with employee training requirements. 4.0 CONCLUSION Anaerobic digestion provides a real opportunity to address farm -related environmental concerns, generate renewable energy, and diversify farm products. It is important to realize, however, that AD systems pose unique challenges and safety risks not experienced on typical farms. These risks can be mitigated by practical measures, including educating employees about the risks associated with the system, implementing strict safety procedures, and having a detailed and up to date EAP that employees are familiar with. Ensuring a safe environment around the AD facility will protect employees and visitors while enhancing the overall performance of the digester. 19 Safety Practices for On -Farm Anaerobic Digestion Systems 5.0 REFERENCES American Petroleum Institute (API). 2008.

The horizontal datum was the North American Datum of 1983, GRS80 ellipsoid. Differences in datum, ellipsoid, projection, or Universal Transverse Mercator zones used in the production of FIRMs for adjacent jurisdictions may result in slight positional differences in map features across jurisdictional boundaries. These differences do not affect the accuracy of this FIRM. All coordinates on this map are in U.S. Survey Feet, where 1 U.S. Survey Foot = 1200/3937 Meters. Flood elevations on this map are referenced to the North American Vertical Datum of 1988 (NAVD 88). These flood elevations must be compared to structure and ground elevations referenced to the same vertical datum. An average offset between NAVD 88 and the National Geodetic Vertical Datum of 1929 (NGVD 29) has been computed for each North Carolina county. This offset was then applied to the NGVD 29 flood elevations that were not revised during the creation of this statewide format FIRM. The offsets for each county shown on this FIRM panel are shown in the vertical datum offset table below. Where a county boundary and a flooding source with unrevised NGVD 29 flood elevations are coincident, an individual offset has been calculated and applied during the creation of this statewide format FIRM. See Section 6.1 of the accompanying Flood Insurance Study report to obtain further information on the conversion of elevations between NAVD 88 and NGVD 29.

Areas of Special Flood Hazard include Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water surface elevation of the 1% annual chance flood. ZONE A No Base Flood Elevations determined. ZONE AE Base Flood Elevations determined. ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevations determined. ZONE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths determined. For areas of alluvial fan flooding, velocities also determined. ZONE AR Special Flood Hazard Area formerly protected from the 1% annual chance flood by a flood control system that was subsequently decertified. Zone AR indicates that the former flood control system is being restored to provide protection from the 1% annual chance or greater flood. ZONE A99 Area to be protected from 1 % annual chance flood by a Federal flood protection system under construction; no Base Flood Elevations determined. ZONE VE Coastal flood zone with velocity hazard (wave action); Base Flood Elevations determined. ® FLOODWAY AREAS IN ZONE AE The floodway is the channel of a stream plus any adjacent floodplain areas that must be kept free of encroachment so that the 1% annual chance flood can be carried without substantial increases in flood heights.

Du lin Permit Capacity: Farrow to Wean Farrow to Feeder Farrow to Finish Wean to Feeder Wean to Finish Feeder to Finish 7344 Gilts Boars Storage Structure: Storage Period: Application Method: Anaerobic Lagoon >180 days Irrigation The waste from your animal facility must be land applied at a specified rate to prevent pollution of surface water and/or groundwater. 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 filter 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 specific 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.

LAND UTILIZATION SUMMARY The following table describes the nutrient balance and land utilization rate for this facility Note that the Nitrogen Balance for Crops indicates the ratio of the amount of nitrogen produced on this facility to the amount of nitrogen that the crops under irrigation may uptake and utilize in the normal growing season. Total Irrigated Acreage: 129.12 Total N Required 1st Year: 28662.96 Total N Required 2nd Year: 16782.65 Average Annual Nitrogen Requirement of Crops: 22,722.81 Total Nitrogen Produced by Farm: 12,264.48 Nitrogen Balance for Crops: (10,458.33) The following table describes the specifications of the hydrants and fields that contain the crops designated for utilization of the nitrogen produced on this facility. This chart describes the size, soil characteristics, and uptake rate for each crop in the specified crop rotation schedule for this facility. 2of11 Reception Area Specifications Year 1 of a 2 year crop rotation 3(a) of 11 3(a) of 11 'Reception Area Specifications Year 2 of a 2 year crop rotation Tract FiEdd- - Irrigated Soil 1st Crop Timeto IstCrop IstCrop LbsN/Ac Lbs N Total lbs N' Acreage Type Code Apply Yield lbs N/Unit Residual /Ac Utilized 2nd Crop Time to 2nd Crop 2nd Crop Lbs N/Ac Lbs N Total lbs N Code Apply Yield lbs N/Unit Residual lAc Utilized 11113-TIMMEME= ,,, 16782.65 3(b) of 11 This plan does not include commercial fertilizer. 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 cut 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 Total/yr Farrow to Wean 0.8 Farrow to Feeder 0.96 Farrow to Finish 3.9 Wean to Feeder 0.07 Wean to Finish 0.27 7344 Feeder to Finish 0.34 2496.96 Gilts 0.39 Boars 0.55 The waste utilization 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 2496.96 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 12484.8 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 41 acreas of land. If you apply the sludge to corn at a rate of 125 pounds per acre, you will need 99.8784 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 table. 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 limitation. 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 applied 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). 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. 8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the surface is frozen. 9 of 11 NUTRIENT UTILIZATION PLAN REQUIRED SPECIFICATIONS 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. 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 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 once every three yeares 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. 11 of 11 EXTENSION 0/Lesn9aNedu) Realistic Yield Expectations for North Carolina Soils The North Carolina Realistic YoW Database is the product of an extensive data gathering and review process conducted by NC Slate Un-say. the Natural Resource Conservation Service, the North Carolina Department of Agricullure and Consumer Services, and the North Carolina Division of Soil and Water Conaervabo, Read More Start Here 1.

Box 856 Warsaw, NC 28398 Phone: (910) 293-3434 Required Documentation The following details of design and materials must accompany all irrigation designs: 1. A scale drawing of the proposed irrigation system which includes hydrant locations, pipelines, thrust block locations and buffer areas where applicable. 2. Assumptions and computations for determining total dynamic head and horsepower requirements. 3. Computations used to determine all mainline and lateral pipe sizes. 4. Sources and/or calculations used for determining application rates. 5. Computations used to determine the size of thrust blocks and illustrations of all thrust block configurations required in the system 6. Manufacturer's specifications for the irrigation pump, traveler and sprinkler(s). 7. Manufacturer's specifications for the irrigation pipe and/or USDA-NRCS standard for IRRIGATION WATER CONVEYANCE. 8. The information required by this form are the minimum requirements. It is the responsibility of the designer to consider all relevant factors at a particular site and address them as appropriate. 9. Irrigation pipes should not be installed in lagoon or storage pond embankments without the approval of the designer. NOTE: A buffer strip of 25' or wider must be maintained between the limits of the irrigation system and all perennial streams and surface waters per NC Statutes. NPDES permitting requires a vegetated buffer strip of 35' or wider be maintained between the limits of the irrigation system and all perennial streams and surface waters per NC Statutes. Sheet6 Narrative of Irrigation System Operation This design dated 6/16/2020 is for a pivot addition and "wetted acreage" determination for an existing facility. The acres were calculated based on the equipment specified and the charts created by NCSU for calculating Area Allowances for Hard Hose Traveler Systems. The pivot acreages were computer calculated based on manufacturers specifications. This design shows the addition of a new pivot (#2), the removal of the solid set Zones 10, 11 & 12, the removal of pulls 4, 6, 7 & 9, and the addition of pull 1 in place of Zone 12. An aerway will be used in place of the removed pulls and zones. Field 11 (Zone 11) is no longer in the plan. Refer to owner's manual and irrigation dealer for information on maintenance, winterization, and operation of system. Note: This design reflects setbacks for NPDES permitting (i.e. 35' vegetated ditch buffers). This design revised 8/16/2024 to reflect the removal of Pull 1 due to the addition of a digester, and updating the pivot acreages to reflect the actual coverage of the pivots. Some field borders were adjusted to reflect current conditions.

The Division of Water Resources of the Department of Environmental Quality (Division) will make the facility's Certificate of Coverage (COC) and Certified Animal Waste Management Plan (CAWMP) available for public review for thirty (30) days prior to issuance of coverage under this Pennit. The animal waste management systems covered by this Permit normally include some type of collection system (flush, pit recharge, scraped lots, etc.); pipes or ditches for transmission of the waste; lagoons or ponds to collect, treat, and store the waste; land application equipment; and sufficient acreage for application of the animal waste at agronomic rates. If prior approval is received from the Director, this Permit may cover innovative treatment systems incorporated into the animal waste management system. All activities authorized herein shall be consistent with the terms and conditions of this Permit. Holders of a COC under this Permit shall comply with the following specified conditions and limitations. I. PERFORMANCE STANDARDS Any discharge of waste that reaches surface waters or wetlands is prohibited except as otherwise provided in this Permit and associated statutory and regulatory provisions. Waste shall not reach surface waters or wetlands by runoff, drift, manmade conveyance, direct application, direct discharge, or ditches not otherwise classified as state waters. The waste management system operated under this Permit shall be effectively maintained and operated as a non -discharge system to prevent the discharge of pollutants to surface waters or wetlands. Application of waste to terraces and grassed waterways is acceptable as long as it is applied in accordance with Natural Resources Conservation Service (MRCS) standards and does not result in a discharge of waste to the surface waters or wetlands. Facilities existing on or prior to April 14, 2003 must be designed, constructed, and operated to contain all waste plus the accumulated volume from a 25-year, 24-hour rainfall event for the location of the facility. A facility that has a discharge of waste that results because of a storm event more severe than the 25-year, 24-hour storm will not be considered to be in violation of this Pen -nit if the facility is in compliance with its CAWMP, the Act and its implementing regulations, and this Permit. Any discharge of waste that reaches surface waters or wetlands is prohibited from a facility constructed after April 14, 2003 that is permitted for a Steady State Live Weight (SSLW) equivalent to or greater than that of 10,000 swine each weighing less than 55 pounds or 2,500 or more swine each weighing 55 pounds. December 5, 2016 NPDES Permit Number NCA200000 Any discharge or application of waste to a ditch that drains to surface waters or wetlands is prohibited except as follows: (a) discharges from the ditches are controlled by best management practices (BMPs) designed in accordance with NRCS standards; (b) the BMPs have been submitted to and approved by the Division; (c) the BMPs were implemented as designed to prevent a discharge to surface waters or wetlands; (d) the waste was removed immediately from the ditch upon discovery; and (e) the event was documented and reported in accordance with Condition IV.21. of this Permit. Nothing in this exception shall excuse a discharge to surface waters or wetlands except as may result because of rainfall from a storm event more severe than the 25-year, 24-hour storm. [40 CFR 412 Subpart C and D; 15A NCAC 02T .1305 (e)] 2. No discharge of waste shall result in a violation of the water quality standards established for the receiving waters as per Title 15A, Subchapter 213, Section .0200 of the North Carolina Administrative Code (NCAC). 3. The facility's COC and its CAWMP are hereby incorporated by reference into this Permit. The CAWMP must be consistent with all applicable laws, rules, ordinances, and standards (federal, state and local) in effect at the time of siting and design and certification of the facility. The Permittee must assess, on an ongoing basis, the effectiveness of the implementation of the CAWMP. The Permittee must modify the CAWMP in order to address any changes needed to maintain compliance with the facility's COC and this Permit. Any proposed change to the CAWMP requires a formal request to modify the COC be submitted to the Division's Central Office. The request shall include the proposed version of the CAWMP with changes from the previous version identified. The Division will review the request to determine if the changes are considered a major modification or a minor modification (see Section VIII. Definitions). Proposed major modifications will be made available for public review and comment for thirty (30) days. The Division will issue a new or amended COC after consideration of public comments and approval of the modification. Note that a sludge removal and application plan is considered a major modification of the CAWMP and is subject to the thirty (30) day public notice requirement prior to approval. A facility may not implement a major modification until a new or amended COC has been issued. Minor modifications do not require public notice; however, the Permittee must receive approval from the Division prior to implementation. The Permittee may request permission from the Division to immediately proceed with a temporary major modification to the CAWMP for a maximum of one hundred eighty (180) days. The Division will make these modifications available for public review for thirty (30) days. The public review must occur prior to the close of the temporary modification period. [40 CFR 122.42(e); 15A NCAC 02T .1305 (e)] Any violation of the COC or the CAWMP shall be considered a violation of this Permit and subject to enforcement actions. A violation of this Permit may result in the Permittee having to take immediate or long-term corrective action(s) as required by the Division or the Environmental Protection Agency (EPA). These actions may include, but are not limited to, modifying the CAWMP; ceasing land application of waste; removing animals from the facility; or reopening and modifying, revoking and reissuing, and/or terminating the COC. [40 CFR 122.41(a); 15A NCAC 02T .1305 (e)] 4. Any proposed increase in the certified design capacity or the SSLW of animals above that authorized by the COC will require a modification to the CAWMP and the COC prior to the actual increase in either waste production or SSLW of animals. December 5, 2016 1) NPDES Permit Number NCA200000 All new and expanding operations must demonstrate that waste management system will satisfy the requirements of G.S. 143-215.1 O.I. 5. No collection, treatment or storage facilities may be constructed in a 100-year flood plain. [G.S. 106-803 (a)] 6. A copy of this Permit, the facility's COC, certification forms, lessee and Iandowner agreements, and the CAWMP shall be readily available at the facility (stored at places such as the farm residence, office, outbuildings, etc.) where animal waste management activities are being conducted for the life of this Permit, unless otherwise specified in this Permit (see Condition IV.20). These documents shall be kept in good condition, and records shall be maintained in an orderly fashion. [40 CFR 122.42(e); 15A NCAC 02T .1305 (e)] 7. If prior approval is received from the Director, facilities that have been issued a COC to operate under this Permit may either add treatment units for the purpose of removing pollutants before land application of the waste or add various innovative treatment processes to the systems in order to determine if the innovative treatment process will improve how the waste is treated s and/or managed. Prior to any approval, the Permittee must demonstrate to the satifaction of the Director that the new treatment unit/innovative treatment process will not interfere with the operation of the existing treatment system and that a process is in place to properly manage and track the pollutants removed. [ 15A NCAC 2T .1308] 8• A COC under this Permit will not be issued to any facility until the applicant demonstrates that the facility can comply with the requirements of state and federal phosphorus -loss standards.

The waste from your animal facility must be land applied at a specified rate to prevent pollution of surface water and/or groundwater. 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 filter 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 speck 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.

LAND UTILIZATION SUMMARY The following table describes the nutrient balance and land utilization rate for this facility Note that the Nitrogen Balance for Crops indicates the ratio of the amount of nitrogen produced on this facility to the amount of nitrogen that the crops under irrigation may uptake and utilize in the normal growing season. Total Irrigated Acreage: 43.89 Total N Required 1st Year: 14304.63 Total N Required 2nd Year. 0.00 Average Annual Nitrogen Requirement of Crops: 14,304.63 Total Nitrogen Produced by Farm: 12,264.48 Nitrogen Balance for Crops: (2,040.15) The following table describes the specifications of the hydrants and fields that contain the crops designated for utilization of the nitrogen produced on this facility. This chart describes the size, soil characteristics, and uptake rate for each crop in the specified crop rotation schedule for this facility. 2of11 Reception Area Specifications - — - ., , — --JIMMMIC „ m®mo�amm�■m�o��amm�a�m „ mmmi,■�s®0im�o���ammm��m�� mmmmo�s®mim�i��omim®m� m■0mmit�ammim�o��ommm�m m®®m�or�sammim�o��amim®mom mmmmo�smmim�o��ammm��m 3(a) of 11 SpecificationsReception Area MF ,::. 3(b) of 11 This plan does not include commercial fertilizer. 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 cut to a height of about two inches before drilling for best results.

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 2496.96 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 12484.8 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 41 acreas of land. If you apply the sludge to com at a rate of 125 pounds per acre, you will need 99.8784 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 table. 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 limitation. 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 Tract Hydrant Soil Type Application Rate Application Amount Crop inlhr ' inches T8200 1A AuB C 0.6 1 T8200 1 B AuB C 0.6 1 T8200 1C AuB C 0.6 1 T8200 10 NbB C 0.4 1 T8200 11 NbB C 0.4 1 T8200 12 NbB C 0.4 1 T8200 sub 1 AuB C 0.6 1 6of11 Additional Comments: This NUP has been revised and now reflects the setbacks required under an NPDES permit.

Box 759 Rose Hill, NC 28458 Farm Operator County: Date: Stan Bowles #2 Duplin 12/21 /93 Soil Investigation to Determine Suitability of Proposed Lagoon Site ------------------------------------- Page 1 A total of three (3) soil borings were taken on this site by Johnny Lanier, SCS, to determine if the existing soils would be suitable for embankment material for the lagoon. All of the borings were made in the vicinity of the proposed lagoon. The benchmark elevation of 50.00 feet is located on the top of 3/4" rebar, 20' SW of C,0+00. The estimated high water table elevation = 48.5 Feet, +/— Using the Unified Classification System, the results of the borings are as follows: Boring #1: F, 6+80; Elev. = 50.5 feet 0 Ft. — 2 Ft. — SM material (silty sand) 2 Ft. — 4 Ft. — SM,SC materials (silty sands; clayey sands) 4 Ft. — 7 Ft. — SC material (clayey sands; sand —clay mixtures) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Boring #2: F, 5+00; Elev. = 50.6 feet 0 Ft. — 2 Ft. — SM material (silty sand) 2 Ft. — 5 Ft. — SC material (clayey sands; sand —clay mixtures) 5 Ft. — 7 Ft. — SM material (silty sand) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Boring #3: 13+50, 5+50; Elev. = 47.1 feet 0 Ft. — 1 Ft. — SM material (silty sand) 1 Ft. — 3 Ft. — SC material (clayey sands; sand —clay mixtures) 3 Ft. — 5 Ft. — SM,SC materials (silty sands; clayey sands) 5 Ft. — 7 Ft. — SC,SM materials (clayey sands; silty sands) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Based on the results of these borings, some of the soils available on this site are suitable to be used as embankment material for the lagoon site. A suitable clay material (SC,CL,etc.) for the liner will be required. QUARTER M FARMS Page 1 P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Stan Bowles #2 Date: 12/21 /93 OPERATION AND MAINTENANCE PLAN This lagoon is designed for waste treatment (permanent storage) with minimum odor control. The time required for the planned fluid level to be reached (permanent + temporary storage) may vary due to soil conditions, flushing operations, and the amount of fresh water added to the system. The designed 6 months temporary storage is an estimated volume based on: 1) waste from animals 2) excess rainfall after evaporation and 3) the largest 24 hour (one day) rainfall that occurs on the average of once every 25 years. The volume of waste generated from a given number of animals will be fairly constant throughout the year and from year to year. This estimate is based on 7.0 inches of excess rainfall which is equal to or exceeds the highest 6 months excess in a year. The average annual excess rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess rainfall will need to be pumped each year. The 25 year rainfall will not be a factor to consider in an annual pumping cycle, but this storage volume must always be available. A maximum elevation is determined in each design to begin pumping and this is usually the outlet invert of pipe(s) from the building(s). If the outlet pipe is not installed on the elevation to begin pumping, a permanent marker must be installed on this elevation to indicate when pumping should begin. An elevation must be established to stop pumping to maintain the minimum treatment depth of 6 feet. Pumping can be started or stopped at any time between these two elevations for operating convenience as site conditions permit, such as weather, soils, crop, and equipment in order to apply waste without runoff or leaching. Land application of waste water is recognized as an acceptable method of disposal. Methods of application include solid set, center pivot guns and traveling gun irrigation. Care should be taken when applying waste to prevent damage to crops. QUARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Stan Bowles #2 OPERATION AND MAINTENANCE PLAN (continued) ----------------------- The following items are to be carried out: Page 2 1. It is strongly recommended that the treatment lagoon be precharged to 1/2 of its capacity to prevent excessive odors during start—up. Precharging reduces the concentration of the initial waste entering the lagoon, thereby reducing odors. Solids should be covered with effluent at all times. When precharging is complete, flush buildings with recycled lagoon liquid. Fresh water should not be used for flushing after initial filling. 2. The attached waste utilization plan shall be followed. This plan recommends sampling and testing of waste (see attachment) before land application. 3. Begin pump —out of the lagoon when fluid level reaches elevation 0.feet as marked by the permanent marker. 66pump-out of the lagoon when fluid level reaches elevation 30 feet or before the fluid depth is less than &Wt feet deep (this prevents the loss of favorable bacteria). The designed temporary storage volume less the 25 year — 24 hour storm volume is 175,168 cubic feet or 1,310,259 gallons. As stated before, this volume will vary considerably from year to year. 4. The recommended maximum amount to apply per irrigation is one (1) inch and the recommended maximum application rate is 0.3 inches per hour. 5. Keep vegetation on the embankment and areas adjacent to the lagoon mowed annually. Vegetation should be fertilized as needed to maintain a vigorous stand. 6. Repair any eroded areas or areas damaged by rodents and establish in vegetation. 7. All surface runoff is to be diverted from the lagoon to stable outlets. 8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization fields adjacent to perennial streams. Waste will not be applied in open ditches. Do not pump within 200 feet of a residence or within 100 feet of a well. 9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters of the United States. The Department of Environment, Health and Natural Resources, Division of Environmental Management, has the responsibility for enforcing this law. QUARTER M FARMS P.O. Box 759 Page 1 Rose Hill, NC 28458 Farm Operator: Date: Stan Bowles #2 12/21 /93 SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS ------------------------------------------ SECTION 1: CLEARING All trees and brush shall be removed from the construction area before any excavation or fill is started. Stumps will be removed within the area of the foundation of the embankment, all fill areas and all excavated areas. All All stumps and roots exceeding one (1) inch in diameter shall be removed to a minimum depth of one (1) foot below final grade. Satisfactory disposition will be made of all debris. The foundation area shall be loosened thoroughly before placement of the embankment material. The lagoon site (and pad site if needed) is to be stripped of topsoil (minimum of 3") and stockpiled for use on dike and pad slopes (finished depth of 2-3"). SECTION 2: CUT—OFF TRENCH A cut—off trench (when specified) shall be installed as shown on the plans. SECTION 3: CONSTRUCTION Construction of excavated and earthfill areas shall be performed to the neat lines and grades as planned. Deviations from this will require prior approval of the SCS. Earthfill shall be placed in a maximum of 6" lifts and shall not be placed in standing water. Compaction shall be performed by the construction equipment or by a sheeps—foot roller during placement. The embankment of the lagoon shall be installed using the more impervious materials. Construction of fill heights shall include ten (10) percent overage for settlement. QUARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Date: Stan Bowles #2 12/21 /93 SPECIFICATIONS FOR CONSTRUCTION (Continued) ----------------------------- To protect against seepage, when areas of unsuitable material are encountered, they will need to be excavated to a minimum of one (1) foot below grade and backfilled and compacted with a SCS approved material (ie — CL, SC, CH). Refer to the soil investigation information in the plans for special considerations. Precautions should be taken during construction to prevent excessive erosion and sedimentation. SECTION 4: VEGETATION All exposed embankment and other bare constructed areas shall be seeded to the planned type of vegetation as soon as possible after construction according to seeding specifications sheet.

All of the borings were made in the vicinity of the proposed lagoon. The benchmark elevation of 50.00 feet is located on the top of 3/4" rebar, 20' SW of C,0+00. The estimated high water table elevation = 48.5 Feet, +/— Using the Unified Classification System, the results of the borings are as follows: Boring #1: F, 6+80; Elev 0 Ft. — 2 Ft. 2 Ft. — 4 Ft. - 4 Ft. — 7 Ft. - 7 Ft. — 11 Ft. = 50.5 feet SM material (silty sand) SM,SC materials (silty sands; clayey sands) SC material (clayey sands; sand —clay mixtures) - SC,CL materials (clayey sands; low plasticity clays) Boring #2: F, 5+00; Elev. = 50.6 feet 0 Ft. — 2 Ft. — SM material (silty sand) 2 Ft. — 5 Ft. — SC material (clayey sands; sand —clay mixtures) 5 Ft. — 7 Ft. — SM material (silty sand) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Boring #3: B+50, 5+50; Elev. = 47.1 feet 0 Ft. — 1 Ft. — SM material (silty sand) 1 Ft. — 3 Ft. — SC material (clayey sands; sand —clay mixtures) 3 Ft. — 5 Ft. — SM,SC materials (silty sands; clayey sands) 5 Ft. — 7 Ft. — SC,SM materials (clayey sands; silty sands) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Based on the results of these borings, some of the soils available on this site are suitable to be used as embankment material for the lagoon site. A suitable clay material (SC,CL,etc.) for the liner will be required. QUARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Page 1 Farm Operator: Stan Bowles #2 Date: 12/21 /93 OPERATION AND MAINTENANCE PLAN ----------------------- This lagoon is designed for waste treatment (permanent storage) with minimum odor control. The time required for the planned fluid level to be reached (permanent + temporary storage) may vary due to soil conditions, flushin operations, and the amount of fresh water added to the system. g The designed 6 months temporary storage is an estimated volume based on: 1) waste from animals 2) excess rainfall after evaporation and 3) the largest 24 hour (one day) rainfall that occurs on the average of once every 25 years. The volume of waste generated from a given number of animals will be fairly constant throughout the year and from year to year. This estimate is based on 7.0 inches of excess rainfall which is equal to or exceeds the highest 6 months excess in a year. The average annual excess rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess rainfall will need to be pumped each year. The 25 year rainfall will not be a factor to consider in an annual pumping cycle, but this storage volume must always be available. A maximum elevation is determined in each design to begin pumping and this is usually the outlet invert of pipe(s) from the building(s). If the outlet pipe is not installed on the elevation to begin pumping, a permanent marker must be installed on this elevation to indicate when pumping should begin. An elevation must be established to stop pumping to maintain the minimum treatment depth of 6 feet. Pumping can be started or stopped at any time between these two elevations for operating convenience as site conditions permit, such as weather, soils, crop, and equipment in order to apply waste without runoff or leaching. Land application of waste water is recognized as an acceptable method of disposal. Methods of application include solid set, center pivot guns and traveling gun irrigation. Care should be taken when applying waste to prevent damage to crops. QUARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Stan Bowles #2 OPERATION AND MAINTENANCE PLAN (continued) ----------------------- The following items are to be carried out: Page 2 It is strongly recommended that the treatment lagoon be precharged to 1/2 of its capacity to prevent excessive odors during start—up. Precharging reduces the concentration of the initial waste entering the lagoon, thereby reducing odors. Solids should be covered with effluent at all times. When precharging is complete, flush buildings with recycled lagoon liquid. Fresh water should not be used for flushing after initial filling. 2. The attached waste utilization plan shall be followed. This plan recommends sampling and testing of waste (see attachment) before land application. - 3. gin pump —out of the lagoon when fluid level reaches elevation afeet as marked by the permanent marker. p pump -out of the lagoon when fluid level reaches elevation T 30 feet or before the fluid depth is less than SM"' feet deep (this prevents the loss of favorable bacteria). The designed temporary storage volume less the 25 year — 24 hour storm volume is 175,168 cubic feet or 1,310,259 gallons. As stated before, this volume will vary considerably from year to year. 4. The recommended maximum amount to apply per irrigation is one (1) inch and the recommended maximum application rate is 0.3 inches per hour. 5. Keep vegetation on the embankment and areas adjacent to the lagoon mowed annually. Vegetation should be fertilized as needed to maintain a vigorous stand. 6. Repair any eroded areas or areas damaged by rodents and establish in vegetation. 7. All surface runoff is to be diverted from the lagoon to stable outlets. 8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization fields adjacent to perennial streams. Waste will not be applied in open ditches. Do not pump within 200 feet of a residence or within 100 feet of a well. 9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters of the United States. The Department of Environment, Health and Natural Resources, Division of Environmental Management, has the responsibility for enforcing this law. QUARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Farm Operator Date: Stan Bowles #2 12/21 /93 Page 1 SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS --------------------------------------- SECTION 1: CLEARING All trees and brush shall be removed from the construction area before any excavation or fill is started. Stumps will be removed within the area of the foundation of the embankment, all fill areas and all excavated areas.

Instructions on reverse side. 2. Attach additional sheets as needed. Date Date 0 INSTRUCTIONS All dams built with technical assistance from the Soil Conservation Service must have a hazard classification assigned by the person responsible for approving the design. Most farm ponds, except in borderline cases, can be classified after a complete field investigation without assuming failure and making breach studies. This data sheet is to be used for recording the information obtained through field studies and for documenting the hazard classification. Where there is a possibility for loss of life or major property damage from a dam failure, an approved breach routing procedure is to be used. (Consult with the area engineer.) Hazard classifications of dams are made by evaluating the possibility for loss of life and the extent of damage that would result if the dam should suddenly breach --that is --a section of the dam be suddenly and completely washed out. It is to be assumed that a wall of water will be released equal to the height of the dam. This flood wave will be reduced in height as it moves down the flood plain. The wave height (depth of flooding) should be evaluated for a sufficient distance downstream until the estimated flood level will not cause significant damage to improvements, such as homes, buildings, roads, utilities, reservoirs, etc. The breach flood level will be reduced depending on the valley storage, slope, and openess of the flood plain; however, in a narrow steep valley slopes steeper than 10% should be given special consideration. One method of evaluation is to compare available valley storage (under flood conditions) to impoundment storage (figured to the top of the dam) for each reach evaluated with a judgment estimate made of the flood wave height at all critical points downstream. Should there be any questions about the hazard classification for a dam, the area engineer should be consulted';',befdre making design commitments. I RV a U.• S.

Box 759 Rose Hill, NC 28458 Farm Operator: County: Date: Stan Bowles #2 Duplin 12/21 /93 Soil Investigation to Determine Suitability of Proposed Lagoon Site ------------------------------------- Page 1 A total of three (3) soil borings were taken on this site by Johnny Lanier, SCS, to determine if the existing soils would be suitable for embankment material for the lagoon. All of the borings were made in the vicinity of the proposed lagoon. The benchmark elevation of 50.00 feet is located on the top of 3/4" rebar, 20' SW of C,0+00. The estimated high water table elevation = 48.5 Feet, +/— Using the Unified Classification System, the results of the borings are as follows: Boring #1: F, 6+80; Elev. = 50.5 feet 0 Ft. — 2 Ft. — SM material (silty sand) 2 Ft. — 4 Ft. — SM,SC materials (silty sands; clayey sands) 4 Ft. — 7 Ft. — SC material (clayey sands; sand —clay mixtures) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Boring #2: F, 5+00; Elev. = 50.6 feet 0 Ft. — 2 Ft. — SM material (silty sand) 2 Ft. — 5 Ft. — SC material (clayey sands; sand —clay mixtures) 5 Ft. — 7 Ft. — SM material (silty sand) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Boring #3: B+50, 5+50; Elev. = 47.1 feet 0 Ft. — 1 Ft. — SM material (silty sand) 1 Ft. — 3 Ft. — SC material (clayey sands; sand —clay mixtures) 3 Ft. — 5 Ft. — SM,SC materials (silty sands; clayey sands) 5 Ft. — 7 Ft. — SC,SM materials (clayey sands; silty sands) 7 Ft. — 11 Ft. — SC,CL materials (clayey sands; low plasticity clays) Based on the results of these borings, some of the soils available on this site are suitable to be used as embankment material for the lagoon site. A suitable clay material (SC,CL,etc.) for the liner will be required. QUARTER M FARMS P.O. Box 759 _ Rose Hill, NC 28458 Farm Operator Date: Stan Bowles #2 12/21 /93 OPERATION AND MAINTENANCE PLAN This lagoon is designed for waste treatment (permanent storage) with minimum odor control. The time required for the planned fluid level to be reached (permanent + temporary storage) may vary due to soil conditions, flushing operations, and the amount of fresh water added to the system. The designed 6 months temporary storage is an estimated volume based on: 1) waste from animals 2) excess rainfall after evaporation and 3) the largest 24 hour (one day) rainfall that occurs on the average of once every 25 years. The volume of waste generated from a given number of animals will be fairly constant throughout the year and from year to year. Page 1 This estimate is based on 7.0 inches of excess rainfall which is equal to or exceeds the highest 6 months excess in a year. The average annual excess rainfall is approximately 8 inches. Therefore, an average of 8 inches of excess rainfall will need to be pumped each year. The 25 year rainfall will not be a factor to consider in an annual pumping cycle, but this storage volume must always be available. A maximum elevation is determined in each design to begin pumping and this is usually the outlet invert of pipe(s) from the building(s). If the outlet pipe is not installed on the elevation to begin pumping, a permanent marker must be installed on this elevation to indicate when pumping should begin. An elevation must be established to stop pumping to maintain the minimum treatment depth of 6 feet. Pumping can be started or stopped at any time between these two elevations for operating convenience as site conditions permit, such as weather, soils, crop, and equipment in order to apply waste without runoff or leaching. Land application of waste water is recognized as an acceptable method of disposal. Methods of application include solid set, center pivot guns and traveling gun irrigation. Care should be taken when applying waste to prevent damage to crops. QUARTER M FARMS Page 2 P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Stan Bowles #2 OPERATION AND MAINTENANCE PLAN (continued) ----------------------- The following items are to be carried out: It is strongly recommended that the treatment lagoon be precharged to 1 /2 of its capacity to prevent excessive odors during start—up. Precharging reduces the concentration of the initial waste entering the lagoon, thereby reducing odors. Solids should be covered with effluent at all times. When precharging is complete, flush buildings with recycled lagoon liquid. Fresh water should not be used for flushing after initial filling. 2. The attached waste utilization plan shall be followed. This plan recommends sampling and testing of waste (see attachment) before land application. 3. Begin pump —out of the lagoon when fluid level reaches elevation 51.50 feet as marked by the permanent marker. Stop pump —out of the lagoon when fluid level reaches elevation 49.30 feet or before the fluid depth is less than 7.80 feet deep (this prevents the loss of favorable bacteria). The designed temporary storage volume less the 25 year — 24 hour storm volume is 175,168 cubic feet or 1,310,259 gallons. As stated before, this volume will vary considerably from year to year. 4. The recommended maximum amount to apply per irrigation is one (1) inch and the recommended maximum application rate is 0.3 inches per hour. 5. Keep vegetation on the embankment and areas adjacent to the lagoon mowed annually. Vegetation should be fertilized as needed to maintain a vigorous stand. 6. Repair any eroded areas or areas damaged by rodents and establish in vegetation. 7. All surface runoff is to be diverted from the lagoon to stable outlets. 8. Keep a minimum of 25 feet of grass vegetated buffer around waste utilization fields adjacent to perennial streams. Waste will not be applied in open ditches. Do not pump within 200 feet of a residence or within 100 feet of a well. 9. The Clean Water Act of 1977 prohibits the discharge of pollutants into waters of the United States. The Department of Environment, Health and Natural Resources, Division of Environmental Management, has the responsibility for enforcing this law. QUARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Date: Stan Bowles #2 12/21 /93 Page 1 SPECIFICATIONS FOR CONSTRUCTION OF WASTE TREATMENT LAGOONS ------------------------------------------ SECTION 1: CLEARING All trees and brush shall be removed from the construction area before any excavation or fill is started. Stumps will be removed within the area of the foundation of the embankment, all fill areas and all excavated areas. All All stumps and roots exceeding one (1) inch in diameter shall be removed to a minimum depth of one (1) foot below final grade. Satisfactory disposition will be made of all debris. The foundation area shall be loosened thoroughly before placement of the embankment material. The lagoon site (and pad site if needed) is to be stripped of topsoil (minimum of 3") and stockpiled for use on dike and pad slopes (finished depth of 2-3") SECTION 2: CUT—OFF TRENCH A cut—off trench (when specified) shall be installed as shown on the plans. SECTION 3: CONSTRUCTION Construction of excavated and earthfill areas shall be performed to the neat lines and grades as planned. Deviations from this will require prior approval of the SCS. Earthfill shall be placed in a maximum of 6" lifts and shall not be placed in standing water. Compaction shall be performed by the construction equipment or by a sheeps—foot roller during placement. The embankment of the lagoon shall be installed using the more impervious materials. Construction of fill heights shall include ten (10) percent overage for settlement. ')DARTER M FARMS P.O. Box 759 Rose Hill, NC 28458 Farm Operator: Date: Stan Bowles #2 12/21 /93 SPECIFICATIONS FOR CONSTRUCTION (Continued) ----------------------------- To protect against seepage, when areas of unsuitable material are encountered, they will need to be excavated to a minimum of one (1) foot below grade and backfilled and compacted with a SCS approved material (ie — CL, SC, CH). Refer to the soil investigation information in the plans for special considerations. Precautions should be taken during construction to prevent excessive erosion and sedimentation. SECTION 4: VEGETATION All exposed embankment and other bare constructed areas shall be seeded to the planned type of vegetation as soon as possible after construction according to seeding specifications sheet.

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) Call 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) Stop 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. E. 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.
