Salisbury Street Raleigh, NC 27699 Re: Butterball, LLC — Construction Permit for Secondary Equalization Tank Dear Mr. Thornburg: 820 O'Fallon Road Weldon Spring, MO 63304 fa btechwws.com 314-478-3344 Fab Tech is pleased to submit this construction permit application on behalf of Butterball, LLC (Butterball). This construction permit application is for the installation of a secondary equalization tank to improve performance of the downstream dissolved air floatation (DAF) system by decreasing flow variability and resulting variance in chemical dosing and performance. There is no increase in loading or flow to the receiving lagoons and/or land application system, the elevation of the proposed system is such that changes to the hydraulic grade line are negligible, and the proposed tank is in the middle of a facility that has undergone recent permit applications (e.g., package plant). Therefore, there are several items listed in the WWIS checklist (AttachmentA) that are not applicable to this submission package. For example, the secondary equalization tank will be constructed from 304 stainless steel and will be placed on an existing gravel parking lost between the existing equalization tank, DAF, receiving lagoon and package plant. The proposed location places it no closer to property boundaries, existing wells, or receiving bodies of water than any of the aforementioned unit processes. Additionally, prior permit applications have determined that none of the existing processes harm, or have to potential to harm, endangered species. Construction of the proposed equalization tank will consist of tapping the influent pipes to the existing tank and installing valving to direct flow, building the foundation and sidewalls of the tank, installing a pressurized air mixing system with blower and diffusers, installing a liquid level monitoring system, routing a tank drain and emergency overflow to the receiving lagoon, and merging the new tank's effluent piping to the existing piping between the DAFs and the existing equalization tank. The difference in the hydraulic grade line between the old and new systems are nominal and no modification to the pumping system is required. The following outline summarizes the sections of the Wastewater Irrigation System Application (Form WWIS-06- 16) that were identified as being required for this project during a conference call with Lauren Plummer on January 26, 2022 and follow up conversations with Mr. Lankford Ruffin of Butterball.

Concrete ingredients shall not be heated to a temperature higher than that necessary to keep the temperature of the mixed concrete, as placed, from falling below the specified minimum temperature. If concrete is placed when the weather is such that the temperature of the concrete would exceed 90' F, the Contractor shall employ effective means, such as precooling of aggregates and mixing water using ice or placing at night, as necessary to maintain the temperature of the concrete, as it is placed, below 90' F. The Contractor shall be entitled to no additional compensation on the account of the foregoing requirements. See subsections 3.4 and 3.5 for additional requirements. J.

Volumetric hatching may be used, provided the same accuracy required for weight hatching is maintained. B. Design and operate the mixers used for mixing the CLSM so that the CLSM as discharged from the mixer is uniform in composition and consistency throughout each batch. C. Place the CLSM such that it flows easily into all openings between the pipe and the excavated trench. In some cases, such as trenches on a slope, a stiffer mix may be required to prevent it from flowing down the trench. In this case, use vibration to ensure that the CLSM completely fills all spaces. D. Lay the pipe on the soil pads and place the CLSM bedding as shown in the drawings. Place bedding under pipe from one side and vibrate so that it flows under the pipe until it appears on the other side. Then add CLSM to both sides of the pipe and vibrate until it completely fills the space between the pipe and the excavated trench bottom. This operation shall follow as closely behind pipelaying operations as possible. Place CLSM in such a way as to prevent uplift or buckling of the pipe. Deposit CLSM as nearly as practicable in its final position. Do not disturb the pipe trench or cause foreign material to become mixed with the cement slurry. E. Do not place backfill above the pipe until the CLSM has reached the initial set. Place and maintain a 6-inch cover of moist backfill cover until additional backfill is placed. If the ambient temperature is 50°F or less, place an additional 6-inch cover of backfill over the 6-inch moist backfill cover prior to the end of the working day. F. Whenever freezing temperatures are imminent, maintain the CLSM at a temperature of not less than 50°F for 24 hours after placement. The temperature of the mix shall be 50°F or greater at the time of placement. Monitor the temperature by placing a thermometer in the CLSM immediately after sampling at the placement site. When freezing weather appears imminent, make ready at the placement site materials that may be required for protection of the CLSM. Delay placement of CLSM until adequate provisions for protection against weather are made. Do not place CLSM bedding in pipe trenches when the trench bottom or walls are frozen or contain frozen material. Backfill placed as cover over the CLSM is prohibited from containing any frozen material. TRENCHING AND BACKFILLING 312333 - 5 3.13 INSTALLING IMPERVIOUS BARRIERS A.

Contractor shall furnish all labor, tools, potable water, and equipment necessary to perform leakage and deflection tests as specified herein. The methods and equipment used to make the test shall be mutually determined by the Engineer and Contractor before any testing is started. For the purpose of testing, a section of the line shall be considered as the length of line between manholes. Any section that fails the test shall be repaired and retested by the Contractor until the leakage and/or deflection limits is within the allowable limits. Water used for exfiltration testing shall not be allowed to be disposed of through the completed sewer line. The Contractor shall provide the required pumps to dispose of test water to the nearest storm sewer or waterway. 3. If inspection or test shows defects, such defective work or material shall be replaced and inspection and tests repeated. Repairs to piping and appurtenances shall be made with new material at no additional cost to the Owner. 4. All visible leaks shall be repaired. B. Gravity Lines: 1. Lines shall be checked for alignment by lamping and visual inspection and deflection by mandrel testing. The pipe between manholes shall not be more than 1/4 of the pipe diameter out of alignment. 2. Deflection limits for flexible sewer pipe shall not exceed five (5) percent of the nominal diameter of the pipe. Deflection limits shall be verified by passing a mandrel through the section of sewer line not less than 30 days after completion of the installation. 3. Perform deflection test using a properly sized mandrel without mechanical pulling devices. 4. Under no circumstances shall the mandrel test be performed prior to the completion of all compaction operations required for surface preparation, regardless of the time of completion of the pipe installation. 5. The sewer mandrel shall be fabricated with a diameter not less than 95 percent of base or average diameter of the pipe as determined by the ASTM standard to which the pipe is manufactured. The mandrel shall be certified by an independent testing laboratory. The current certification shall be submitted and approved by the Engineer prior to using the mandrel. 6. The Contractor shall provide video verification of the sewer main on all lines 30 days after substantial completion. 7. Air Test: a. In addition to the visual inspection, the Contractor shall perform a low pressure air test on all pipe installed. b. Testing methods for PVC pipe shall conform to the applicable requirements of ASTM F1417. c. Testing methods for concrete pipe shall conform to the applicable requirements of ASTM C 924. d. Testing methods for vitrified clay pipe shall conform to the applicable requirements of ASTM C828. e. For making the low pressure air tests, the Contractor shall use equipment specifically designed and manufactured for the purpose of testing sewer pipelines using low pressure air. The equipment shall be provided with an air regulator valve or pressure relief valve set so that the internal air pressure in the pipeline cannot exceed 9 psig. All air used shall pass through a single control panel. SANITARY SEWER SYSTEMS 333100 - 8 f. Pneumatic plugs shall have a sealing length equal to or greater than the diameter of the pipe to be tested. Pneumatic plugs shall resist internal test pressures without requiring external bracing or blocking. g. The Contractor shall be extremely cautious when testing with low pressure air. It is extremely important that the various plugs be installed in such a way as to prevent blowouts. Inasmuch as a force of 250 Ibf (112N) is exerted on an 8-inch (230 mm) plug by an internal pipe pressure of 5 psi (34 kPa), it should be realized that sudden expulsion of a poorly installed plug or of a plug that is partially deflated before the pipe pressure is release can be dangerous. h. NO ONE shall be allowed in the manholes during testing. i. The section of pipe between successive manholes shall be sealed with suitable plugs. Do not overpressure the line. Do not exceed 9.0 psig. One of the plugs shall have an orifice through which to pass air into the section of pipe being tested. The air supply source (air compressor) shall have a 9 psig pressure relief valve. The air supply line shall have a positive on -off valve and suitable means for readily disconnecting it at the control panel. A second orifice in the plug shall be used for constantly reading the internal pressure of the pipe. This orifice shall be continuously connected to a pressure gauge having a range of from 0 to 10 psi. The gauge shall have minimum divisions of 0.10 psi and shall have an accuracy of ± 0.04 psi. j. The line under test shall be slowly pressurized to approximately 4 psi. Regulate the air supply so that the pressure is maintained between 3.5 and 4.0 psig for at least 2 minutes. The air temperature should stabilize in equilibrium with the temperature of the pipe walls. Disconnect the air supply and decrease the pressure to exactly 3.5 psi before starting the test. k. Determine the time required for the pressure to drop from 3.5 psi to 2.5 psi, and compare this interval to the required time to decide if the rate of air loss is within the allowable. Tables 1 and 2 show the minimum holding times for PVC pipe listed by diameter. If the pressure drops 1.0 psig before the appropriate time shown in Table 1 has elapsed, the air loss rate shall be considered excessive and the pipe section has failed the test. For testing of long sections or sections of larger diameter pipes, or both, a timed -pressure drop of 0.5 psig shall be used in lieu of the 1.0 psig drop as shown in Table 2. I. Upon completion of the test, open the bleeder valve and allow all air to escape. Plugs should not be removed until air pressure in the test section has been reduced to atmospheric pressure. 8. An infiltration/exfiltration test may be performed with prior approval by the Engineer. a. Infiltration Test: An infiltration test shall be performed when the crown of the sewer line is below the ground water table. The amount of water leaking into the sewer shall be measured by the use of appropriately sized weirs designed specifically for this purpose and approved by the Engineer. The allowable leakage shall not be more than 50 gallons per day, per mile of pipe, per inch nominal diameter. The section of pipe to be tested shall be pumped dry before the start of the test. b.

FLEXIBLE PIPE COUPLINGS AND EXPANSION JOINTS 400722 - 7 3.2 INSTALLATION OF TYPE 11 FLEXIBLE ELASTOMERIC INTERNAL JOINT A. Store the membranes in a cool, dry environment away from direct sunlight. Do not remove the rubber joint seals from the plastic bags prior to use. Store seals in a cool, dry environment and do not remove from their plastic bags until required for use. Do not allow them to remain in direct sunlight. B. Surface Preparation of Joint Area: Prepare the area of pipe either side of the joint where the actual lip seals make contact with the pipe to a finish that will allow the lip seals to bed consistently and so provide a permanent seal. C. Surface Lubrication: Immediately prior to fitting the seal, clean the area with a dry brush and coat with lubricant that is a nontoxic vegetable soap compatible with the composition of the flexible joint seal. Apply the lubricant using a paintbrush over the ground area. Do not pick up dust deposits from the unground surface into the lubricant and therefore onto the ground surface. D. Positioning the Seal: Prior to placing the seal, coat the area of pipe which will be covered with the seal with an epoxy coating and allow to partially set up prior to seal installation. Check the seal for damage. Check that the test unit is tight before fitting the seal in place. Place the flexible joint seal in position bridging the joint gap, guided by the marks. Position the seal accurately on the ground areas. The test unit in the seal should be located at either 9 o'clock or 3 o'clock position. Position the seal parallel to the joint gap. E. Positioning Retaining Bands: Place two stainless steel radiused shims, 6 inches long and 3/64-inch- thick, underneath the wedge area in the grooves, to provide a bridge that will transmit the radial load evenly to the flexible joint seal, as the bands are expanded. Then place the stainless steel bands in the grooves provided in the seal. Temporarily lock both bands in position. F. Expanding the Seal into Position: Use the hydraulic expanding device to apply a set pressure to the retaining bands of the flexible joint seal. 1. When positioning the expander in line with the retaining band, ensure that the band remains in the groove of the flexible joint seal and does not become moved or dislodged. Ensure the expander is positioned correctly on the band. 2. The expander is expanded which radially transmits a load against the retaining band and flexible joint seal. Hold this pressure for at least two minutes. The range of pressure registered on the expander shall be 4,000 psi minimum and 5,000 psi maximum. 3. A space is provided at bottom dead center position of the expander that exposes the grooved -end cleats of the retaining band. Fit a radiused locking wedge piece between the exposed gap of the expanded band ends. Select a size of wedge having a slight interference fit between the band ends, and tap the wedge (leading edge first) into position, locking in the compression of the flexible joint seal. The radius of the wedge shall equal the radius of the pipe. 4. Release the hydraulic pressure from the expander and repeat the procedure on the second retaining band of the seal. 5. Repeat this entire operation (i.e., re -expanded) not before 30 minutes have elapsed after the first expansion. This allows for any seal relaxation that may take place and usually a slightly larger wedge can be fitted. The load forces transmitted by the expander have been determined from test data and should not be altered by changing the pressure used to activate the expander. G. Testing the Seal, Test 1: Apply two individual pressure tests to the seal before closing the pipeline. Apply the first test after each section has been completed and not before 30 minutes have elapsed after the final fitting of the seal. Apply a pressure of 10 psig. Because of the excessive ballooning to the center membrane of the seal (that will occur at this higher pressure), lock a restraining device called a "test band" in its expanding position during testing. If the pressure test indicates leakage, determine the cause and repeat from Step E. H. Testing the Seal, Test 2: In the second test, introduce 5 psig through the valve in the flexible joint seal. Sustain this pressure while applying a soap and water test to the outer edge and entire body of the seal. Inspect for leakage. If pressure test indicates leakage, determine the cause and repeat from Step E. Testing Valve Assembly: After the final test of 5 psig, seal the test valve of the flexible joint seal with a countersunk hex head completion plug using a nontoxic thread -sealing compound on the threads. Remove installation hardware, test band, and pressure gauges from the pipe. 3.3 PAINTING AND COATING A. Coat buried flexible pipe couplings (including joint harness assemblies), transition couplings, FLEXIBLE PIPE COUPLINGS AND EXPANSION JOINTS 400722 - 8 segmented sleeve couplings, and flanged coupling adapters per Section 099000. Coat buried bolt threads, tie bolt threads, and nuts per Section 099000. Then wrap the buried couplings with polyethylene wrap. B.

Regulatory Agency............................................................................................................ 6 Introduction 1.1 Objective This manual will provide insight into the operation and general maintenance of the secondary equalization tank prior to the dissolved air floatation (DAF) system at the Butterball plant in Mount Olive, North Carolina. 1.2 Scope of the Manual This manual identifies various components of the equalization tank and general operation and maintenance of said tank. Detailed operation and maintenance information for specific components is supplied by the vendor of that equipment. System Overview 2.1 Physical Description The 2-million-gallon stainless steel equalization tank is approximately 120-ft in diameter and 24- ft high with stairs to a lighted viewing and sampling platform at the top. There are two (2) 10-in influent pipes with butterfly valves to control flow into the tank. Mixing is supplied by coarse bubble aeration with a positive -displacement blower set next to the tank. A single 12-in effluent line directs flow out of the tank to the existing pipe leading to the DAF building. An 8-in tank drain with butterfly valve intersects with an 8-in tank overflow pipe that discharges into the lagoon. Liquid level in the tank is monitored by a pressure transducer. 2.2 Drawings and Specifications Detailed drawings and specifications may need to be referenced for significant maintenance and/or repair. These documents are part of the plan set developed by 21 Design with the assistance of Fab Tech Wastewater Solutions. A complete set of these plans shall be provided to the owner and operator for future reference. 2 Routine System Operation 3.1 General Discussion The equalization tank supports optimal function of the dissolved air flotation (DAF) system. 3.2 System Operating Strategy The purpose of the equalization tank is to convert variable flow from plant processes to consistent flow for optimal DAF performance. The overall strategy is to provide as consistent a flow rate as possible to the DAF. 3.3 Equipment Operation and Control Very little day-to-day hands-on operation of the equalization tank is to be expected. Blower operation for mixing and liquid level for hydraulic management are the two primary operating parameters The equalization tank is mixed by bubbles from a coarse -bubble diffuser grid. The diffusers themselves are considered maintenance -free because there are no membranes that need to be serviced at regular intervals. Air to the coarse -bubble diffusers is provided by a positive -displacement blower. The blower is designed for continuous operation, regardless of the water height in the tank, and is controlled with hand switches. The operators should refer to the manufacturer's IO&M manual for specific maintenance information regarding air filters, oil and lubrication, and belts. A pressure transducer is attached to the side of the tank and used to determine liquid level height within the tank. The signal from the transducer is sent to the Operator's SCADA system and alarms for high- and low-water levels should be part of the programming for that system. The high-water alarm should be set for 22-ft of liquid height, or 1-ft below the overflow pipe. The low-water alarm should be set at 1-ft above the top of the effluent pipe to prevent the DAF feed pumps from running dry. The Operator is encouraged to review the manufacturer's IO&M manual for specific maintenance information on the transducer, which may include routine cleaning and/or calibration. There are three sets of valves that control flow to and from the tank. Only one equalization tank should be used at a time. Both influent and effluent valves should be closed to whichever tank is in standby. The third valve set is for the tank drain. This valve should normally be closed. The overflow pipe from the tank was designed without a valve to prevent operational error. All valves should be exercised on a regular basis and the Operator is encouraged to review the manufacturer's IO&M for specific instruction. 3.4 Operator Duties The Operator should visit the equalization tank daily, but no less than once per week, to ensure blower is operating and to verify accurate liquid level feedback. The Operator must document the operation, maintenance, and visitors to the system in a daily log and notify the Owner immediately of any overflows or bypasses. The Owner, in turn, is required to notify the Wilmington Regional Office (see Section 5) of an overflow or bypass within 24-hours of becoming aware of the incident. The Operator must provide written notification to the Owner if system repairs or modifications are needed to ensure all regulatory compliance. The main plant should be contacted if there is a power outage at the equalization tank, DAF, or connecting pumps. 3.4.1 Daily Routine The operator should log flows from the processing plant over the course of several days and weeks to determine that average flow requirement for the DAF. That average flow can then be adjusted as needed to account for the limitations of process water storage across the two equalization basins (existing and new). 3.4.2 Emergency Power Plan The only component solely obligated to the proposed equalization tank is the blower, which is not a critical item for operation of the equalization tank. Power failure to effluent pumps could result in the tank being overfilled if the influent pumps were to remain in operation, but over filling the tank would result in a bypass discharge around the DAFs and directly into the receiving lagoon. Therefore, no emergency power plan is necessary for the proposed equalization tank because the system can tolerate septic wastewater due to prolonged detention and sufficient storage capacity exists, between the equalization tank and receiving lagoon, that no potential for overflow exists. 4 Maintenance 4.1 General Timely and prompt maintenance is imperative for the performance of any treatment system and will extend the overall life of the components. 4.2 Site Access Fences, gates, and security guards restrict access to the water resource reclamation facility for safety and security. 4.3 Daily Maintenance No daily maintenance is required. General daily inspection is suggested but should be conducted no less than once per week. Inspection should consist of ensuring blower is operating, checking for symmetrical mixing (free of dead zones), and checking water level in the tank. 4.4 Periodic Maintenance The following sections provide general direction and notes. Please refer to the manufacturer's recommendations and IO&M manual(s) for detailed information. 4.4.1 Blowers Refer to manufacturer's instructions. General maintenance includes air filter, checking discharge pressure and adjusting pressure relief valve, changing oil, inspecting belts, etc. 4.4.2 Valves Exercising valves on a periodic basis is crucial to valve longevity. Please refer to the manufacturer's instructions for more information. 4.4.3 Diffusers Each diffuser features a small duckbill valve to prevent water from backing up into the aeration system. Failure of this valve is not operationally critical. There is the potential for plugging of the aeration distribution lines should one or more valves fail, and if the blower is turned off for an extended period. "Dead zones" will be apparent when blower function resumes. In this case the lines will need to be purged and duckbill valves in the area of the dead zone should be inspected and replaced as needed. 4.4.4 Pressure Transducer Please refer to the manufacturer's IO&M manual for periodic calibration and service requirements.
