BACKGROUND The purpose of this report is to describe, evaluate and document Conrad Farms LLC's compliance with the Clean Water Act (CWA) at its Grafton, Ohio facility on April 18, 2022. This inspection was performed pursuant to Section 308(a) of the Federal Water Pollution Control Act, as amended. Conrad Farms LLC (Conrad Farms) is a medium dairy animal feeding operation with approximately 225 mature milking cows, 25 dry cows, 125 heifers and 125 calves. Prior to the inspection, EPA had observed potential areas of discharge at Conrad Farms to waters of the United States, namely the East Branch Black River, in aerial photographs. From aerial photographs it appears that any uncontrolled discharges from drainage swales and/or overflows of containment lagoons/ponds would flow into the East Branch Black River which flows along the southwest, south, and southeast property lines of the facility. The East Branch Black River flows to the Black River which flows into Lake Erie. The East Branch Black River, the Black River and Lake Erie are all waters of the United States and traditional navigable waterways. 2.

No operators were immediately present upon arrival, however, at approximately 9:20 a.m., EPA was met by Mr. Richard Conrad and Mr. David Conrad, the co-owners of the farm. EPA representatives presented their credentials to Mr. Richard Conrad, co-owner, and primary operator of the farm. After EPA presented their credentials to Mr. Richard Conrad, EPA conducted the entry interview to explain the purpose for the inspection and EPA's authority to conduct the inspection at the Animal Feeding Operation. EPA's authority comes from Section 308 of the Clean Water Act. Mr. Richard Conrad was the primary facility participant during the inspection, as Mr. David Conrad attended to daily dairy operations and participated as he was able in between managing dairy operations. EPA confirmed the number of dairy cows included 225 mature milking cows, 25 dry dairy cows, 125 heifers and 125 calves. There are no bulls on site. Young male calves are only at the facility for two or three days before being sold. Breeding is done through artificial insemination. EPA explained that the inspection would include questions from an inspection checklist, a facility walk-through to determine compliance with the Clean Water Act and a closing conference. EPA explained that if a discharge was observed during the walk-through, samples would need to be collected. EPA asked Mr. Richard Conrad if he would want split samples in the event samples were collected. Mr. Richard Conrad declined to receive split the samples.

The nursery has less inside storage for used pen- pack. Richard Conrad was unsure of the current location of the original as-built drawings for the storage structures. Yes, when stackable pen-pack solids storage areas within the animal barns are full and land application cannot be conducted, the additional pen-pack solids are stored uncovered on the silage/feed storage pad. Any run-off from leachate or storm water on the silage/feed storage pad drains towards the east edge of the concrete storage pad which is designed and graded to flow south into the south retention pond. No. Richard Conrad had stated that the facility had just begun pumping manure out of the manure lagoons for land application for the first time this year in April 2022 prior to the inspection. 6 What amount of manure or process wastewater was removed the last time the storage structure was emptied, either partially or completely? Do the facility personnel inspect and keep records of all diversion devices? Do the facility personnel inspect and keep records of all impoundments? Do the facility personnel inspect and keep records of all the water lines? Do the facility personnel perform routine visual inspections and keep records of the production area? Does the waste storage system have a managed outfall or discharge point? Has the facility had any documented discharges of livestock waste to surface water in the past year? Are there safety devices installed around any manure storage ponds? (Barriers at the end of manure push off platforms, fences around pond, signage.) Additional Information: Conrad Farms LLC April 18, 2022 Richard Conrad estimated that the facility had pumped 165,000 gallons of manure out of the manure lagoons in the week prior to the inspection. (22 loads x 7,500 gallons per load) Personnel inspect diversion devices during daily operations, but no records are kept of these inspections. Personnel inspect impoundments during daily operations, but no records are kept of these inspections. Personnel inspect water lines during daily operations, but no records are kept of these inspections. Richard Conrad stated that facility personnel do perform routine visual inspections of the production area, but they do not keep formal records of those visual inspections. There are no designed and managed outfalls or discharge points in the waste storage system. However, EPA observed an overflow discharge of production wastewater from the south retention pond during the inspection. This process wastewater overflow from the pond flowed through the adjacent woods and discharged into the East Branch Black River. Richard Conrad stated that he was not aware of any documented discharges of livestock waste to surface waters in the past year. When asked specifically about discharges from the south retention pond, Richard Conrad stated that he was unsure if the south retention pond had had any discharges to surface water in the last year. Yes. There are safety cables that extend across the push ramps into both manure lagoons. No. 7 Conrad Farms LLC April 18, 2022 Table 5: Livestock Waste Management Describe the way manure is collected and disposed of at the facility: A skidsteer with a squeegee attachment is used to manually scrape manure solids from the cow lanes and the freestall barns into either the smaller north manure lagoon or the larger south manure lagoon. The areas are scraped approximately three times per day or as needed. Richard Conrad estimated that the amount of liquid manure generated annually was about 2 million gallons, although he wasn't sure of the exact annual volume. Each manure lagoon is emptied down to its concrete floor twice per year. Manure in both manure lagoons is land applied. The facility also pumps liquid from the south retention pond into the manure lagoons when the manure needs to be further liquified so that it is easier to pump out of the lagoons for land application. The transfer of liquid from the south retention pond to the manure storage lagoons is done with a submersible pump and lay-flat overland hoses (approximately 3-inch/4-inch diameter hoses). The south retention pond receives run-off and leachate from the bunkered concrete silage/feed storage pad (which can also be used for short term solid pen-pack storage as needed when interior storage areas are full) as well as the production area process wastewater run-off and storm water run-off that is collected in the sediment pods and pumped into the retention pond. The sediment pods are a series of three shallow depressions along the east side of the facility that contain process wastewater and storm water run-off from the northeast corner of the milking parlor and the cow treatment areas. The pods flow in series from the first pod to the third pod and allow for settling of solids from the process wastewater and stormwater run-off. According to Richard Conrad, the south retention pond is pumped down 2 times per year at which time the liquid and solids are land applied. Liquid from the south retention pond is also used as mix water to thin the manure in the two manure storage lagoons to improve the pumpability of the manure for land application. Production area run-off from the northeast side of the facility including roof run-off and run-off from the unroofed portion of the north end of the animal treatment coral (east of the milking parlor) flows into the swale and subsequently into the series of sediment pods. From the last pod in the series, flow is pumped via a float activated submersible pump to the retention pond at the south end of the facility. Describe the way used bedding is collected and disposed of at the facility: Waterbed mattresses covered with a layer of bedding sawdust on top of concrete bases are used for bedding for the milking cows. The sawdust layer on top of each of the waterbed mattresses is raked 3 times per day with new sawdust added once per day. The raked used sawdust is mixed with the manure that is scraped into the manure lagoons. Sawdust and straw pen-pack are used in the barns housing the heifers, dry cows, and the nursery. The pen-pack for heifers and dry cows is collected approximately 3 times per week and pen-pack for the nursery is collected once per week. When pen-pack bedding is collected, new bedding material is added as needed. Used bedding is 8 Conrad Farms LLC April 18, 2022 generally land applied as it is removed from the barns. However, there is approximately 3 to 4 months of storage capacity for used bedding within the heifer and dry cow barns during wet months and winter weather. Bedding is then land applied as weather permits. Are mortality records kept? Yes. Describe the way mortalities are managed at the facility: The mortalities are stored outside behind the commodity barn while the facility waits for the rendering service to pick up the mortalities. The renderer is George Flescher out of Akron, Ohio. Richard Conrad stated that Mr. Flescher picks up mortalities within a several hours of the request for mortality pick-up. What type of method is used to provide City water is used for plate cooler water drinking water for the animals? which is then recycled as drinking water for the animals in the holding area (Drinkers with float system? Nipple adjacent to the milking parlor. In the waters? If nipple waters, is backflow holding area, drinking water is provided in prevention installed?) two large water tubs which are automatically filled while milk is cycling through the plate coolers. Once the plate cooler water cycling stops, the drinkers stop filling. City water is also directly used as make-up water for all drinkers at the dairy. All other fountain style drinkers for the barns are float activated and the water for these drinkers is city water. Describe the way spilled drinking water is collected and disposed of at the facility: Spilled water from the drinkers is scraped into the manure lagoons when the floors of the freestall barns are scraped. Any spilled drinking water in the barns using bedded pen-pack would fall onto the used pen-pack bedding and become part of the bedding. Used pen-pack can be stored within the animal barns for future land application or immediately land applied depending on the land application weather conditions. Describe the way mist cooling water is collected and disposed of at the facility: The facility has a mist cooling water system. The water for the mist cooling system comes from the clean water pond that Richard Conrad refers to as the farm pond. The mist cooling water would fall to the floor within the barns and either become mixed with the manure solids that are scraped into the manure lagoons or would become mixed with the solid pen-pack material that is routinely removed and land applied or stored within the barns. Describe how chemicals are stored and how used or spilled chemicals are collected and disposed of at the facility: Bulk chemicals are stored in a curbed section of the chemical room on the east side of the milking parlor. Foot baths are located in the return alleys and the milking parlor. Bulk teat dip chemical containers are located in the chemical room within the curbing. Teat dip is used in the milking parlor. Any teat dip chemical that would spill on the floor would be scraped up with the manure that is pushed to the smaller north manure 9 Conrad Farms LLC April 18, 2022 lagoon or flushed during cleaning to the milking parlor floor drain. The milking parlor floor drain discharges by gravity through a tile into an exterior reception sump on the east side of the milking parlor. The reception sump has an automatic float to pump manure flush water from the milking parlor to the smaller north manure lagoon. Describe the way water that has been used to wash/flush barns are collected and disposed of at the facility: Flush water is not used in other barns. Describe where water comes from that is used to clean and/or flush. (Wells, city, etc.) Two kinds of flush water are used in the milking parlor. Clean water from the farm pond/clean water pond is used for the final floor flush water. Small hoses connected to city water are used for rinsing off the actual milking units. City water is used for the milk tank wash water. Describe the way feed is contained and how runoff from feed is collected and disposed of at the facility: Feed is contained on the bunkered concrete silage/feed storage pad. Feed and silage are generally covered, with one end open for access. Any run-off from leachate or storm water on the concrete silage/feed storage pad drains towards the east edge of the storage pad which is designed and graded to flow south into the south retention pond. Feed supplements (soy hulls, soybean meal, dry cow mix and milking cow mix) are stored within the enclosed commodity barn located off the southwest corner of the west freestall barn. New bedding material and straw is stored in a barn on the south side of the dry cow barn. If a dairy, describe how process wastewater from the plate cooler water is collected and disposed of at the facility: City water is used for the plate cooler water. The used plate cooler water is recycled as drinking water for the animals. Any spilled water from the drinkers is scraped into the manure lagoons when the floors of the barns are manually scraped. Any spilled drinking water in the barns using pen-pack would fall onto the used pen-pack bedding and become part of the used bedding that is then land applied. If a dairy, describe how process wastewater from the cleaning of the milking parlor is collected and disposed of at the facility: The milking parlor floor is manually scraped to remove manure solids first. The manure solids are scraped to the holding area adjacent to the milking parlor. When the holding area floor is scraped, the manure, including the milking parlor floor scrapings, is scraped into the smaller north manure lagoon. The milking parlor has a floor drain that discharges the parlor wash/flush water by gravity through a tile into an exterior reception sump on the east side of the milking parlor. The reception sump has an automatic float to pump parlor wash/flush water from the milking parlor to the smaller north manure lagoon. 10 Conrad Farms LLC April 18, 2022 If a dairy, describe how process wastewater from the cleaning of the milk tanks is disposed of at the facility: City water is used to wash the milk tanks. The process wastewater from the cleaning of the milk tanks flows into a floor drain that directs the wastewater through a tile to the exterior reception sump on the east side of the milking parlor. The reception sump has an automatic float to pump manure flush water from the milking parlor to the smaller north manure lagoon. If a dairy, how many times per day are 3 times per day. cows milked? Table 6: Land Application and Disposal of Manure and Process Wastewater Does the facility perform and keep records of the Yes, a contracted agronomist manure testing? is hired to complete annual manure sampling. The records are kept at the dairy. When was the last time a sample was taken of the manure and/or process wastewater? Richard Conrad stated that the last manure sampling was conducted in 2021. Richard Conrad stated that manure/wastewater sample results are consistent with little variation in nutrient values. Describe the process to take the manure and/or process wastewater sample. Richard Conrad stated that the contracted agronomist collects the manure sample. The facility has the contractor sample each manure lagoon and combine them for a composite sample of the manure from the lagoons. The facility is not sampling the liquids of the south retention pond. The liquids in the south retention pond have been land applied in the past; however, the liquids are routinely used as mix water that is added to both manure storage lagoons to further liquify the manure so that it is easier to pump out of the lagoons. 11 Number of acres available for land application: Are land application records kept? Who applies the manure and process wastewater to the fields? Are weather conditions at time of application kept? (24 before - 24 after) Does the facility perform and keep records of the soil testing? Conrad Farms LLC April 18, 2022 Richard Conrad estimated the facility has approximately 1,150 acres available for land application. Approximately of those acres are owned and of the acres are leased. Richard Conrad stated that the facility documents load counts, gallons per acre spread rates and other information necessary to be entered into the computer program for fertilizer/land application. The facility uses their own equipment to apply manure to the fields. For fields that are further away from the dairy, they hire a custom applicator to transport the dairy's manure to those fields, but the dairy conducts the actual land application. For fields closer in proximity to the dairy, the facility will transport the manure/wastewater to the fields for land application. Richard Conrad stated that they do check the weather forecasts for land application purposes. However, facility personnel are not documenting the weather forecasts. Richard Conrad stated that the facility uses a contractor to conduct field soil testing and the records are maintained. All fields are sampled on a rotating schedule on alternating years (every other year). Leased fields are also sampled by the farm's contractor. Each application field has a distinct recipe for variable rate fertilizer and seed supplement fertilizer application. 12 Is manure transferred off-site to another party? Are manure transfer records maintained? Do facility personnel perform periodic inspection of land application equipment? Conrad Farms LLC April 18, 2022 Richard Conrad stated that occasionally manure/process wastewater is transferred offsite to another party. Richard Conrad stated that he does not keep formal manure transfer records. Generally, any manure transfers go to local grain producer's fields within a few miles of the dairy and Conrad Farms transports the manure to be transferred. Richard Conrad stated that visual inspections of the equipment are done during regular operations and use of the equipment, but there are no formal records of the inspections of the equipment. Table 7: Receiving Surface Waters Describe the surface flow pathways: At the time of the inspection, EPA observed the southeast edge of the south retention pond to be overflowing and discharging into the tall grass area. EPA followed the flow through the grassed area and into the woods located to the southeast of the south retention pond. EPA observed the flow as it continued southeast/east through the woods and then northeast/north along the edge of the woods adjacent to the bank of the East Branch Black River where the flow then discharged into the East Branch Black River.

The walk-through started in the milking parlor at the north end of the Conrad Farms facility. Richard Conrad led EPA through the milking parlor, into the adjacent chemical storage room and then south to the milking parlor cow holding area. A small section of the holding area on the south side of the milking parlor is not roofed. Any precipitation that falls in this unroofed section of the holding area would flow directly into the north manure lagoon via the push ramp or be pushed into the north manure lagoon as manure solids in the holding area are routinely scraped by the skidsteer into the north manure lagoon. At this location Dave Conrad joined Richard Conrad briefly on the walk-through. EPA was also able to observe the cow treatment area adjacent to the cow holding area. The cow treatment area is used for those animal treatment activities that would require the cow to be placed in a catch chute. This area is not used for teat dip or foot bath treatments. The cow treatment area is mostly roofed, but also has a small unroofed section on its north side. EPA observed and 16 Conrad Farms LLC April 18, 2022 collected photograph documentation of the cow treatment area and the concrete reception sump that receives flush/wash water from the milking parlor (photographs DSCN3674, DSCN3675). The reception sump is located on the exterior east side of the cow treatment area. The reception sump has a float activated pump that pumps the flush/wash water into the smaller north manure lagoon. EPA also observed one of the water tubs in the holding area that provides recycled plate cooler water for the cows to drink. EPA observed the east and west freestall barns for milking cows. The milking cows are confined in freestall barns on water-filled mattresses with saw dust on top. EPA walked along the exterior of the west side of the west freestall barn and observed the farm pond/clean water pond (Photograph DSCN3676). The clean water pond is designed to overflow via a PVC pipe under the driveway and into a catch basin located on the east side of the driveway in a grassed area on the west side of the west freestall barn's fresh pen section for recently calved cows (Photograph DSCN3759). This catch basin also receives storm water from downspouts on the west barn and runoff from the grass swale on the west side of the west freestall barn (Photographs DSCN3760 and DSCN3761). Richard Conrad stated that this catch basin drains to a surface outlet in the woods on the south end of the farm property and does not outlet to the river. EPA continued walking south along the driveway and then east between the cow barns to view the manure lagoons on the east side of the facility. EPA observed the smaller north manure lagoon (Photograph DSCN3677) and the larger south manure lagoon (DSCN 3678). EPA observed pumping equipment in place in the larger south manure lagoon as the facility had recently begun land application of lagoon manure for the spring season. EPA continued walking between the west side of the nursery and the fresh straw/sawdust storage barn, and then along the east edge of the concrete silage/feed storage pad. EPA observed run-off from the silage/feed storage pad draining to the concrete drainage trough along the east side of the pad and flowing south into the south retention pond (Photographs DSCN3679, DSCN3680 and DSCN 3681). EPA also observed a pile of stacked used pen-pack on the silage/feed storage pad (Photograph DSCN3682). Richard Conrad explained that when the indoor storage areas for used pen-pack and bedding material are at capacity, the concrete silage/feed storage pad can temporarily be used for emergency storage of the material until land application can take place. EPA continued walking with Richard Conrad southeast around the southern ends of the new bedding/straw barn and the heifer barn to observe the series of three connected sediment pods on the east side of the facility. Liquid flows from a grassed swale, into the first sediment pod, which in turn flows into the second sediment pod that subsequently flows into the last sediment pod. The series of sediment pods is located at a lower elevation than the rest of the production area. From the higher elevation EPA observed the black corrugated plastic reception sump that receives flow from the last pod of the series. There is a submersible pump in the sump that operates on a float and pumps the collected process wastewater run-off from the last sediment pod into the northeast corner of the south retention pond (Photograph DSCN3683). The process wastewater run-off in the sediment pods is comprised of run-off from the unroofed portion of the cow treatment area (process wastewater), roof run-off from the roofed portion of the cow treatment area, 17 Conrad Farms LLC April 18, 2022 and roof run-off from the milking parlor. From this elevation, EPA also photographed the series of sediment pods (Photographs DSCN3684 and DSCN3685). Dave Conrad rejoined Richard Conrad on the site walk-through of the sediment pods. EPA and the facility representatives walked downhill to the reception sump for the last sediment pod and photographed the inside of the sump to document the influent pipe from the last sediment pod and the sump effluent pipe that transfers the pumped pod liquid up to the south retention pond (Photograph DSCN3686). EPA photographed the grassed earthen berm constructed between the last sediment pod and the wood line along the bank of the East Branch Black River. This earthen berm extends east and west along the wood line (Photographs DSCN3688 and DSCN3689). EPA then walked the sediment pod flow pathway from the last pod, upstream to where the initial sediment pod swale begins at the northeast corner of the milking parlor building (Photographs DSCN3687, DSCN3690, DSCN3691 and DSCN3692). After walking the flow path for the series of sediment pods, EPA, Richard Conrad, and Dave Conrad walked the perimeter of the south retention pond. At the northeast edge of the south retention pond, EPA observed a length of black plastic piping rising out of the bank of the pond. Richard Conrad identified that this pipe discharges the liquid flow from the last sediment pod reception sump into the south retention pond. There was also a submersible pump present that is used to transfer liquids from the pond to the manure storage lagoons as needed. EPA photographed the northeast edge of the pond to document the black pipe, submersible pump, and the adjacent blue lay-flat overland hose (Photographs DSCN3693 and DSCN3694). Evidence of solids deposition within the south retention pond was also visible in Photograph DSCN3694. EPA walked south/southwest from the northeast edge of the south retention pond (Photograph DSCN3695) to the southeast edge of the south retention pond. EPA photographed the grassed and partially bermed area to the east of the south retention pond (Photographs DSCN3696 and DSCN3697). At the northeast edge of the south retention pond, EPA observed that the south retention pond was actively discharging. EPA followed the active discharge flow through the grassed area and into the woods located to the south/southeast of the south retention pond. EPA continued to follow the discharge flow southeast through the woods and then northeast/north along the edge of the woods adjacent to the bank of the East Branch Black River where the flow then discharged into the East Branch Black River. EPA explained to Richard Conrad that due to the active overflow of the pond that was flowing through the woods into the East Branch Black River, EPA would be collecting samples. EPA walked back to the vehicles to gather sampling and monitoring equipment for sample collection. Due to a drop in temperature, the rainfall had become a light snowfall. On the walk back to the south retention pond to conduct sampling, EPA took an additional photograph (DSCN3698) of the run-off flowing along the east edge of the silage/feed storage pad and flowing towards the south retention pond. EPA began sampling at approximately 12:00 p.m. ET. While sampling and following the flow pathway from the active overflow point on the southeast edge of the south retention pond to the discharge point into the East Branch Black River, EPA documented the 18 Conrad Farms LLC April 18, 2022 continuous flow path and sample locations with photographs (Photographs DSCN3699 through DSCN3755). EPA also collected field monitoring measurements of temperature, dissolved oxygen, conductance, and pH using a YSI 556 Multi Probe System at each sample location. The YSI 556 was calibrated at the EPA office in Westlake, Ohio prior to the inspection on April 18, 2022. Following the collection of samples and field monitoring measurements from three sample locations, EPA walked back to the vehicles to prepare the sample bottles for E. coli and biochemical oxygen demand analysis for transport to the contract laboratory in Akron, Ohio. During the walk back to the EPA vehicles, EPA observed the black pipe at the northeast edge of the south retention pond discharging sediment pod liquid into the south retention pond. EPA photographed the flow from the pipe (Photographs DSCN3757 and DSCN3758). EPA also documented the stormwater flow in the drainage swale along the exterior of the west side of the west freestall barn located on the east side of the driveway. The flow in the swale enters into a catch basin located in the grassed area on the west side of the west freestall barn (Photograph DSCN3759) between the commodity barn on the south end and the section of the west freestall barn for recently calved cows. This catch basin receives storm water from downspouts on the west freestall barn as well as runoff from the grass swale (Photographs DSCN3760 and DSCN3761). Richard Conrad stated earlier in the inspection walk-through that this catch basin drains to a surface outlet in the woods on the south end of the farm property and does not outlet to the river. EPA sampled at the following locations: 1. EPA collected sample S01 from the process wastewater overflow discharge from the southeast edge of the south retention pond. (N 41 11.369', W 82 06.107') (Photographs DSCN3699 and DSCN3700) 2. EPA collected sample S02 from the process wastewater discharge pathway where the flow path curves north/northeast at the east edge of the woods to flow along the edge of the woods. This location is approximately 2/3 of the distance between the south retention pond overflow and the final discharge point into the East Branch Black River. (N 41 11.334', W 82 06.062') (Photographs DSCN3732, DSCN3733 and DSCN3736) 3. EPA collected sample S03 at the location where the process wastewater flow from the south retention pond overflow discharges into East Branch Black River. (N 41 11.3562', W 82 06.0842') (DSCN3751 through DSCN3754). 2.3 Closing Conference and Post-Inspection EPA (Inspector Vincent) held a closing conference with Mr. Richard Conrad explaining that EPA is concerned with the overflow discharge from the southeast edge of the south retention basin. 19 Conrad Farms LLC April 18, 2022 Table 12: Post Walk-Through Were specific Areas of Concern discussed with facility personnel? Yes. Who were the Areas of Concern discussed with? Mr. Richard Conrad Specific Areas of Concern Discussed: EPA explained that the discharge from the south retention pond was observed to be flowing through the thick grass, south/southeast though the adjacent woods and then finally discharging into the East Branch Black River. EPA exlained that this was a concern because the south retention pond receives process wastewater run-off and leachate from the silage/feed storage pad, as well as the process wastewater run-off and stormwater run-off that is contained in the series of sediment pods and subsequently pumped into the south retention pond. The discharge from the south retention pond therefore is comprised of production area process wastewater and contaminated stormwater. The discharge is an unpermitted discharge. Were any deficiencies or areas of concern addressed or fixed during the inspection? If so, list what was done. EPA did not observe any of the areas of concern being addressed at the time of the inspection. However, following the inspection, Mr. Conrad informed EPA on May 9, 2022, that he had hired an environmental consulting firm, ENVi Environmental LLC. Technical consultants from ENVi visited the site on May 2, 2022 and provided a subsequent May 11, 2022 summary letter describing their assessments of the manure and storm water management systems on site. The summary identified that the south retention pond "requires maintenance and redesign to accommodate the waste/water volume that is directed to it." The letter also stated that the pond capacity should be designed to accommodate a 25-year, 24-hour storm event. Additional recommendations were also outlined. A copy of this letter was provided to EPA by Mr. Conrad, and is available in the inspection file for review. Mr. Conrad also provided EPA with photographs of the lowered manure levels in the north and south manure lagoons following land application activities after the inspection. Those photographs are available in the inspection file for review. Compliance assistance materials given to facility personnel: EPA provided a copy of the 2022 U.S. EPA Small Business Resources Information Sheet. Exit Time: Approximately 3:05 p.m ET. Disposable Boots Left at Facility? No. Table 13: Waterway Documentation List the pathway taken by EPA inspectors to document the waterway at the facility. EPA walked along the perimeter of the south retention pond and observed the southeast edge of the south retention pond to be overflowing, discharging into the tall grass area. EPA followed the discharge flow through the grassed area and into the woods located to the south/southeast of the south retention pond. EPA continued to follow the discharge flow southeast through the woods and then northeast/north along the edge of the woods adjacent to the bank of the East Branch Black River where the flow then discharged into the East Branch Black River. 20 Table 14a: Sampling Information Were samples taken?
