The NOI shall be submitted and a Certificate of Coverage (COC) issued prior to any discharge of stormwater associated with industrial activity that has a point source discharge to surface waters of the state or to a separate storm sewer system conveying discharges to surface waters. Any owner or operator not wishing to be covered or limited by this General Permit may make application for an individual National Pollutant Discharge Elimination System (NPDES) permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual permit shall be made at least 180 days prior to commencement of discharge. This General Permit does not cover activities or discharges covered by an individual NPDES permit until the individual permit has been rescinded or revoked. Any person conducting an activity covered by an individual permit, but which could be covered by this General Permit may request that the individual permit be revoked and coverage under this General Permit be provided. If industrial materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion from permitting must submit a No Exposure Certification NOI form to the Division; must receive approval from the Division; must maintain no exposure conditions unless authorized to discharge under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually. Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load (TMDL) for pollutants for stormwater discharges is established. A TMDL is for one or more watersheds with one or more impaired waters. The TMDL sets one or more pollutant-loading limits that affects one or more watersheds, or portion of a watershed, draining to one or more impaired waters. A list of approved TMDLs for the state of North Carolina can be found at https://deq.nc.gov/about/divisions/water-resources/planning/modeling-assessment/tmdls. To not be subject to the TMDL, each facility with one or more discharges to watersheds affected by a TMDL must demonstrate it does not have reasonable potential to violate applicable water quality standards for those pollutants identified in the TMDL as a result of discharges. If the Division determines that discharges have reasonable potential to cause water quality standards violations, the facility shall apply for an individual permit 180 days prior to the expiration date of this General Permit. After that individual permit becomes effective, the facility will no longer have coverage under this General Permit. Note although there is not a TMDL for every impaired water, the permittee must identify impaired waters in the General Location Map, as outlined in the Stormwater Pollution Prevention Plan (SWPPP), Part B of this permit. The Department of Environmental Quality - Division of Water Resources integrated reports (https://deq.nc.gov/about/divisions/water-resources/planning/modeling-assessment/water- quality-data-assessment/integrated-report-files) include assessments of waters monitored in North Carolina. Use the most recent final report to identify impaired waters. Until this permit expires or is modified, revoked, or rescinded, the permittee is authorized to discharge stormwater to the surface waters of North Carolina or a separate storm sewer system which has been treated and managed in accordance with the terms and conditions of this General COC. Page 1 of 32 Permit No. NCG060000 COC is hereby incorporated by reference into this General Permit. Any violation of the COC is a violation of this General Permit and subject to enforcement action as provided in the General Permit. Any other point source discharge to surface waters of the state is prohibited unless it is an allowable non-stormwater discharge or is covered by another permit, authorization, or approval. The discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality Standards. Discharges allowed by this permit must meet applicable wetland standards as outlined in 15A NCAC 2B .0230 and .0231 and water quality certification requirements as outlined in 15A NCAC 2H .0500. If activities covered by this permit expand or change after issuance of the COC such that the types of discharges are affected, the permittee must first contact the Division to determine if modifications to the COC are necessary. r compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order, or decree.

The Site drains via on-site ditches (normally dry). As shown on Figure 2 Area Stormwater Drainage Map, the Site drains to an unnamed tributary, then to Gasters Creek, then to the Upper Little River and then to Lake Trace. Stormwater run-on from north of the Site drains through the facility’s Stormwater drainage system. The Site does not lie within a critical watershed area. None of the receiving water bodies mentioned above are impaired. Stormwater runoff from the Site discharges through one of three outfalls. Outfall 001 / Discharge Sampling Point No. 1 primarily has runoff from the shipping area, compactors, Team Member parking lot, and from around the refrigeration building. There is also some off-site drainage through this point. Outfall 002 / Discharge Sampling Point No. 2 primarily has runoff from the roof and the flour silo area. Outfall 003 / Discharge Sampling Point No. 3 has runoff from the flour silo area and oil tanks containment area. 5 of 34 The locations of the Outfalls are as follows and are shown on the Detailed Site Plan attached to this document: Outfall/Sampling Point No. 1 - N 35° 27' 31” W 79° 08' 25" Outfall/Sampling Point No. 2 - N 35° 27' 34” W 79° 08' 19" Outfall/Sampling Point No. 3 - N 35° 27' 36” W 79° 08' 17" Figure 3 Detailed Site Plan is presented in Appendix A of this document. Figure 3 provides detailed regarding the location of Outfalls, location of various storage areas and facility activities, local topography and drainage areas. 6 of 34 7 of 34 8 of 34 5.0 SITE ACTIVITIES 5.1 Storage Practices Used cooking oil, which is generated internally from the cookers, is stored in totes (approx. 270 gallons each) and the totes are placed within an empty trailer located in the parking lot until they are picked up by the vendor for recycling purposes. A maximum of 28 totes will be stored on the trailer and the trailer itself will serve as the secondary containment.The cookers are cleaned as production permits. Liquid shortening and soybean oil is stored in four 12,658-gallon aboveground storage tanks (2-liquid shortening and 2-soybean oil) are located on the East Side of the plant. The tanks are within a concrete secondary containment wall. Five flour silos are located inside near the east wall of the plant. 55-gal drums of skimmed floatables (solids, used lubricating oils, and used ammonia oil) are placed under a storage shelter adjacent to the wastewater treatment plant. Ammonia for the refrigeration system is stored in a 20,000-gallon tank outside behind the ammonia engine building. Diesel fuel is stored in a 264 gallon above ground storage tank located adjacent the east side of the refrigeration building. The diesel fuel is used to power the refrigerated trailers that are used as temporary product storage. This area has a secondary containment dike with a roof and tin sides. Waste flour/dough is feed via a hooper into trailers operated by Smithfield. Full trailers are sometimes parked on-site until vendor pickups occur. The hopper and trailer(s) are located outside on the west side of the plant. Other materials such as bags of minor ingredients and other compounds used in plant operations are stored indoors in designated storage areas. 5.2 Loading and Unloading Activities Bulk loads of flour are received via tanker trucks and are unloaded into silos by a vacuum system. Liquid Shortening and Soybean cooking oil arereceived via tanker trucks and pumped into 12,658 gallon tanks located on the East Side of the plant. One used soybean oil tank is unloaded by a pump truck. (Secondary containment provided to all tanks listed). All oil and shortening delivers are supervised by a Tyson Team Member to ensure any spills or leaks are corrected immediately if they occur. Finished product is loaded into trailers. On occasion, fully packed trailers are temporarily parked on-site prior to shipping. 9 of 34 5.3Outdoor Process Areas This facility has silos and above ground storage tanks located outdoors. At no time does an intermediate or finished product become exposed to precipitation. A compactor is provided for miscellaneous trash. A separate compactor is provided for the collection of broken chips and taco shells. Both compactors and the attached roll-off container are of the enclosed type, which minimize infiltration of rainfall. 5.4 Dust/Particulate Generating Processes Flour dust accumulates on the ground in the immediate vicinity of the storage silos. Flour dust and by-product particulates (including soybean oil) also accumulate on the plant's roof through exhaust vents. Small quantities of scrap product (broken or otherwise unsuitable chips) spill onto the ground around the compactor. During dry period, dust is generated from the unpaved parking lot areas. 5.5 Waste Disposal Practices Food waste and by-products (dough, broken chips, used cooking oil) are collected separately and sold for animal consumption and other recyclable uses. The dough and broken chips are compacted into a trailer and then transported off-site for reuse. Floatables, solids, and used oil are skimmed from the waste process water and placed in 55-gallon plastic containers and then delivered by a private contractor for disposal. The soybean oil by-product is separated and used in the manufacture of animal feed. The trash dumpsters are serviced weekly by Waste Management. This facility also collects cardboard boxes and aluminum cans for recycling. 5.6 Summary of Potential Stormwater Pollution Areas and Operations The facility was evaluated for existing and potential sources of pollution. There are several areas where material handling and storage activities take place outside of the main manufacturing building. There are six areas of concern which occur outside of the manufacturing building that pose a threat of pollution are: 5.1.1Shippingdock area: The trench drain along the shipping docks discharges to a stream that is usually flowing. Wash water enters directly into the drain. Pollutants that are detected in this water are by-products which can contribute to BOD, TSS, and COD in Stormwater. The chip/dough 10 of 34 compactor is also located in this area which contributes to the same problem in that chips/doughoften spill from the compactor and enter the trench drain. Housekeeping efforts occur each day for these issues. 5.1.2Roof runoff: Flour dust and cooking oil settles onto the roof from the exhaust vents. Rainwater washes the residue off the roof into the storm drain system. Filter systems are installed around the exhaust vents to prevent runoff to the storm drains. 5.1.3Skimmed solids: Solids that are skimmed from the Gyra-Vib screen are augured into 55-gallon containers, which are then placed on pallets under a shelter in an area that is not exposed to rainfall. Secondary containment is provided for these containers. 5.1.4 Flour silos: Flour dust is observed on the paved area around the silos. The process of unloading bulk flour creates dust. Team Members sweep up the flour dust in this area on a daily basis. 5.1.5 Diesel Fuel Storage: A 264-gallon steel tank on legs is located near the pre- treatment building. This tank has a secondary containment structure and is covered on three sides and overhead from precipitation. 5.1.6 Sediment runoff: Sediment runoff from unpaved area could potentially enter the storm drains. BMPs (ie. Filter socks and wattles) have been placed in order to help control the excess sediment runoff. 11 of 34 6.0 SIGNIFICANT SPILLS AND LEAKS In the event of a significant spill or leak, details of each occurrence would be described in this section of the SWPPP along with a description of corrective actions taken to mitigate spill impacts.

Utilize used oil tank to collect contaminated rainwater for collection by vendor. 2/9/2019 Spill from Wastewater Absorbent pads/booms and Trained employees on Pre-Treatment (Outfall pumped sill material from the proper filling of #1)drain.containment tank SUMMARY (07-14-2016): At 1:37 pm on Thursday July 14, 2016, Mike Perry and Kevin Allen (Corporate Environmental Area Manager) were performing a visual inspection of the storm water outfalls when we noticed a suspicious floating sheen at outfall #3. Upon investigation it was determined that a silo was overfilled during the unloading process the night before by a new team member in training, which resulted in excess flour landing on the concrete pad below. Dry cleaning procedures were immediately initiated upon discovery the next morning. The majority of flour was captured and placed in a scrap module. The remaining flour on the concreted area was rinsed along with some oil residual, which eventually made its way to a storm drain and settled in the creek through outfall #3. A spill boom was placed downstream to keep the contaminated water from leaving the property. SWS Environmental services was called for cleanup. At approximately 3:30 pm SWS arrived and was instructed to vacuum out contaminated water and soil. 800 gallons of mostly water, with very little sand/silt, oil residual and flour was recovered and sent to Greensboro for proper disposal. Of the 800 gallons of total recovery, it is estimated that 30 gallons was actually flour, oil, sand/silt. Mike Perry and Kevin Allen conducted a post cleaning inspection to confirm all contamination 12 of 34 was removed and water was clear. See attached pictures of before and after cleanup as well as SWS manifest. Management is addressing cleaning procedures when it comes to water use. SUMMARY (02-09-2019): On Saturday 2/9/2019, The Mexican Original Sanford Plant experienced a spill of approximately 23 gallons of oil/washdown water from the sanitation lift station tank. Less than 1 gallon of the spill conveyed across the parking lot and reached the stormwater drain on the east side of the facility that is on property. A section of the stormwater creek downstream of the spill was diked off and the contaminated water was pumped out and transferred back into the facility wastewater drain system. Other affected areas were cleaned up using pumps and pigmat absorbents. The location contacted the emergency response number listed on the facilities stormwater permit. As a result, the incident was reported to the North Carolina Department of Environmental Quality. 7.0 EVALUATION FOR NON-STORM WATER DISCHARGES The stormwater outfalls have been evaluated for the presence of non-stormwater discharges. On an annual basis, the site is formally inspected for the presence of non-stormwater discharges. That inspection is performed by the Environmental Manager, or a Representative, and certified by the Plant Manager. The current form used to document the inspection for non-stormwater discharges is included in Appendix B of this document. Completed records are filed at the facility electronically. 8.0 STORMWATER SAMPLING REQUIREMENTS Stormwater sample collection is required quarterly(every 3 months) during a measurable storm event from Outfalls 001, 002 and 003 according to the requirements of General Permit NCG060000. A measurable storm event is a storm event that results in an actual discharge from the permitted site outfall and one in which at least 0.10 inches of precipitation occurred. The previous measurable storm event must have been at least 72 hoursprior to the sampled event.The quarterly events must occur during the period from January 1 through March 31, April 1 through June 30, July 1 through September 30, and October 1 through December 31. At least 30 days must separate the quarterly sampling events. Grab samples from each outfall must be collected within the first 30 minutes of discharge. In accordance with the General Permit, samples are analyzed for chemical oxygen demand (COD), oil and grease (O&G), total suspended solids (TSS), field pH and temperature. For each sampled measurable storm event, the total precipitation must be recorded using either an on-site rain gauge or local rain gauge reading. Visual observation of samples and each outfall is also required quarterly and is performed when laboratory samples are collected. The following observations are required: color, odor, clarity, floating solids, suspended solids, form, oil sheen and observation of erosion or deposition at each outfall. Visual observations are recorded on the Visual Observation Form included in Appendix B of this SWPPP. Completed Visual Observation Forms and other records and summaries of the stormwater sample data are filed at the facility and are part of this SWPPP. 13 of 34 9.0STORMWATER MANAGEMENT STRATEGY 9.1 Feasibility Study A review was conducted which addressed the feasibility of revising any procedures with the goal of improving storm water quality. The factors considered include technical practicality, water quality benefits, and economic costs. Based on the results of the feasibility study, there are no proposed operational changes. 9.2 Secondary Containmentand Records The General Permit requires secondary containment for liquid materials, Section 313 priority pollutants and hazardous substances in order to prevent leaks and spills of those materials from contaminating stormwater runoff. In accordance with the requirements of the Site’s Spill Prevention Control and Countermeasures Plan (SPCC Plan), all oils stored outside are surrounded by secondary containment. Except for the anhydrous ammonia, no hazardous wastes are currently stored outside. Inspections of the oil storage areas are performed to ensure tanks, containers and secondary containment structures remain structurally sound. The outdoor secondary containment structures do accumulate stormwater. As needed, that water is either released to the environment or pumped out and properly disposed. Accumulated stormwater is only released to the environment if it is uncontaminated. In accordance with the facility’s SPCC Plan, monthly inspections of oil tanks, oil containers and secondary containment inspections and secondary containment drainage events are performed and documented. Semiannually, inspections are performed as part of the SWPPP using the Secondary Containment Inspection Checklist presented in Appendix B. The water is visually inspected and documented by a trained member of the SPCC Team. If the water presents any evidence of contamination it is not released to the environment. This facility uses compounds that may contain hazardous materials or Section 313 water priority chemicals, but the quantities for most materials are below established threshold and/or reporting limits. Anhydrous ammonia is the only Section 313 chemical stored in quantity at the facility. The facility stores more than 10,000 pounds of anhydrous ammonia which is used in the refrigeration system. The anhydrous ammonia refrigeration system is not contained within secondary containment, however, it is managed under very strict controls according to OSHA’s Process Safety Management System requirements.Potential releases of anhydrous ammonia would not present a threat to stormwater, however, if leaked or spilled it would vaporize to atmosphere. 14 of 34 9.3 Spill Prevention and Response Procedures Facility management will utilize existing facility manpower/equipment and any necessary local contractors to control any spillage. All spills will be reported to a member of the facility’s Stormwater Pollution Prevention. Spill reporting to regulatory agencies will be in conformance with all applicable State and Federal requirements. The SPCC plan details the procedures to follow in the event an oil spill. The facility’s Emergency Response Plan details procedures to following in the event of a hazardous chemical spill. 10.0 BEST MANAGEMENT PRACTICES SUMMARY The General Permit requires the facility owner/operator to implement feasible best management practices (BMPs). The BMPs will be implemented, routinely inspected, reviewed and updated annually as needed. As listed below, numerous BMPs were identified as feasible and effective for this facility and have been implemented. 10.1 Good Housekeeping Maintain dry and clean floors. Floors will be swept each shift, with residue placed in designated containers. The areas around the shipping docks and flour silos will be swept as needed. Brooms, dustpans, and mops are available for access and use. Trash and other waste material will be picked-up on a daily basis and disposed of properly. A separate holding bin has been provided for oily rags. The exterior grounds will be inspected weekly. Litter and other trash will be disposed of properly. All equipment will be visually inspected for leaks and other conditions that could lead to a discharge of a pollutant. Materials will be stored in adequate containers to prevent leakage. Containers will be labeled with the name of the substance, stock number, expiration date, health hazards, safe handling requirements, and first aid information. 15 of 34 10.2 Site-Specific BMPs Shipping Dock Area Periodic sweeping will be performed in and around the shipping dock area. Wet washing is prohibited. Bulk liquid Operations The facility’s SPCC Plan addressed bulk liquid loading and unloading procedures. Each event will be supervised by a Tyson Team Member and inspected for a criteria checklist designed to greatly minimize the risk of spills or leaks. In the event of a spill or leak, spill response procedures will be implemented as described in the SPCC Plan. Fueling Activities Team Members are instructed not to “top off” tanks when refueling and to minimize fueling activities during times of heavy rainfall. An oil spill kit is located near the outdoor diesel fuel storage tank and Team Members involved in fueling activities are trained to contain and clean up leaks and spills if they occur. Erosion Control Erosion is controlled at the facility through a combination of hard pavement surfaces, gravel surfaces and vegetated areas. 10.3 Preventative Maintenance Preventative maintenance at the facility involves regular inspections and testing of equipment and operational systems. These inspections uncover conditions such as cracks or slow leaks, which could cause breakdowns or failures that result in discharges of chemicals that could contaminate stormwater. As issues are identified, they are corrected by making adjustments, repairs or replacements. The following items are subject to periodic inspections. Monthly inspections of secondary containment structures. Monthly inspections of the silos and oil tanks. Pumps. These devices are subject to frequent inspection and maintenance that includes lubrication, balancing, repacking bearings, and tightening of support bolts and pipe connections. The pump manufacturers' recommendations will be followed. 16 of 34 Pipes and Supply lines. Steam lines, product transport systems, and water supply pipes will be inspected quarterly. Special attention will be made to supports, connectors, and valves. Inspections of the facility and all stormwater systems will occur as part of the Preventative Maintenance and Good Housekeeping Program at a minimum of a semiannual schedule, once during the first half of the year (January to June), and once during the second half (July to December), with at least 60 days separating inspection dates. SWPPP Amendment and Annual Update. The SWPPP will be updated whenever there is a change in design, construction, operation, site drainage, maintenance, or configuration of the physical features which may have a significant effect on the potential for the discharge of pollutants to surface waters. 10.4 Annual Comprehensive Site Inspection and SWPPP Review Annually, a Comprehensive Site Inspection will be performed and documented on the Comprehensive Site Inspection Form included in Appendix B. Additionally, all aspects of the SWPPP will be reviewed and updated on an annual basis. The annual update will include: An updated list of significant spills or leaks of pollutants for the previous three (3) years, or the notation that no spills have occurred; A written re-certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges; A documented re-evaluation of the effectiveness of the on-site stormwater BMPs. A review and comparison of sample analytical data to benchmark values (if applicable) over the past year, including a discussion about Tiered Response status. The facility will use the NCDENR’s Annual Summary Data Monitoring Report (DMR) including in Appendix B of this document. 11.0 TRAINING Storm Water Pollution Prevention Team Members review the requirements of the SWPPP annually. Team Members responsible for inspections, maintenance of equipment, BMPs and spill response are trained annually. Annual training of affected team members will occur to inform Team Members responsible for implementing activities identified in the SWPPP of its components and goals. The training will address at a minimum spill response, good housekeeping, and material management practices. All training is documented and records are maintained at the facility. 17 of 34 12.0 REPORTING REQUIREMENTS A Discharge Monitoring Report (DMR) must be submitted to the NCDENR no later than 30 days from the date the facility receives the sampling results from the laboratory. Samples analyzed in accordance with the terms of this general permit will be submitted to the NCDENRon Discharge Monitoring Report (DMR) forms provided by the NCDENR.Exceedances of benchmark limits will be investigated and reported as required by the General Permit and corrective actions will be implemented as needed. 18 of 34 TIER ONE, TIER TWO TIER THREE RESPONSES/ACTIONS An exceedance of any benchmark value shall require a tiered response for that outfall. A single exceedance of a benchmark value shall require a Tier One response for that outfall. Two benchmark value exceedances in a row shall require a Tier Two response for that outfall. Four benchmark exceedances for a parameter within the permit term shall require a Tier Three response for that outfall. TIER ONE RESPONSES TH 4 Quarter 2021 19 of 34 TH Quarter 2021 (cont’d) 4 Benchmark exceedance for TSS on Outfall #3 Possible Causes – It is believed that ongoing construction for a new dock area created the TSS benchmark exceedance for Outfall #3. The construction is located just adjacent to and upstream of Outfall #3. BMPs were utilized during the construction, however, it appears as if this was the cause. Actions to Reduce Concentrations – Improve upon the current BMPs that are in-place and limit construction (earth disturbances) during dry periods. Action Implemented/Resolved – Construction of the dock area completed Spring/Summer 2021. 20 of 34 st Quarter 2022 1 21 of 34 st Quarter 2022 (cont’d) 1 Benchmark exceedance for TSS on Outfall #1 Possible Causes – Excess sedimentation from the facility grounds. A portion of the facility grounds within Outfall #1 watershed is not paved and is made-up of dirt and gravel. The gravel material is a “softer” aggregate that breaks down after repeated use (ie. heavy trucks traveling over). The excess sedimentation was washed down the storm drain(s) which is believed to have caused the exceedance in TSS for Outfall #1. Actions to Reduce Concentrations –Improve upon the current BMPs that are in-place. Action Implemented/Resolved – Filter socks and wattles added to protect storm drains. Completed May 2022.. 22 of 34 nd Quarter 2022 2 23 of 34 nd Quarter 2022 (cont’d) 2 Benchmark exceedance for COD on Outfall #3 Possible Causes – Flour entering the storm drain that directly feeds Outfall #3. Just before the sampling event, a malfunction occurred on one of the flour silos which resulted in excess flour being deposited onto the pavement outside the flour silo. The flour was subsequently washed down the storm drain with the next rainfall event. Actions to Reduce Concentrations – Repair malfunctioning equipment associated with the flour silo. Action Implemented/Resolved – Flour silo repaired July/August 2022. 24 of 34 st Quarter 2023 1 Believed 25 of 34 st Quarter 2023 (cont’d) 1 Benchmark exceedance for COD on Outfall #2 Possible Causes – Flour entering the storm drain that directly feeds Outfall #2. A storm drain located just adjacent to the flour silo and leading directly to Outfall #2 was previously temporarily closed off by placing a magnetic drain coverover the storm drain. The storm drain will eventually be permanently closed due to the creation of a new dock area. The seal on the magnetic cover was accidentally broken, thus, allowing flour material to enter the storm drain. Actions to Reduce Concentrations – Create a tighter seal for the storm drain to prevent material from entering. Action Implemented/Resolved– Pending as of 2/13/2023. 26 of 34 APPENDIX A –DETAILED SITE PLAN 27 of 34 APPENDIX B – FORMS 28 of 34 Non-Stormwater Discharge Assessment Form 29 of 34 Secondary Containment Inspection Checklist Directions: Complete this checklist semi-annually.
