Agri-Mark, Chateaugay site, is one of four (4) member-owned dairy cooperative facilities that produces cheddar and other similar cheeses. Whey, a by-product of cheese production, is partially processed on-site and is sold as a commodity or sent to other cooperative facilities for further processing. The facility employs 106 personnels and operates 24 hours per day, 7 days per week, 365 days per year with scheduled shut-down days for maintenance. It is categorized under Standard Industrial Classification (SIC) 2022- Natural, Processed, and Imitation Cheese and the North American Industry Classification System (NAICS) 311513 - Cheese Manufacturing.

Dates: September 19-20, 2023 Agri-Mark; Chateaugay site, uses well water for sanitary and manufacturing operation. Based on the facility's March 2022 "Water Withdrawal Report Form," the average day withdrawal is 512,423 gallons (GPD) from the private wells. Well water is disinfected with sodium hypochlorite (NaOCl) prior to storage in the water tower. From the tower, the water is piped throughout the facility for sanitary use such as bathroom and breakroom areas, and manufacturing operation. Sanitary wastewater is segregated and discharged directly into the Village of Chateaugay Sewer Collection System. The Chateaugay site receives cow milk from regional dairy farms to initiate the start of the manufacturing process. Attachments used in the transfer of raw milk to the raw milk storage tanks undergo a CIP (Cleaning-In-Place) for food safety. From the storage tanks, the raw milk is pumped into a pasteurizer to kill harmful bacteria. Once pasteurized, the milk is pumped into the Cheese Vats and starter ingredients are added. After cooking for approximately one-hour between 90-102F, the cheese separates from the raw whey. The cheese continues to the Dry Matting Conveyor (DMC) for curdling, draining, and cutting. From the DMC, the cheese is conveyed onto the Finishing Table. As residual whey drains from the table, salt is manually spread over the cheese. Once the table is full, a rotating arm is attached above to mix the salt into the cheese. After mixing, the rotating arm is replaced by a shovel. The shovel moves the cheese into the screw auger that feeds the Block Forming Towers. The cheese is formed into square blocks and are packaged. The blocks of cheese are vacuum sealed by the Pressurized Vacuum Sealers. Once vacuum sealed, the cheese goes into cold storage. The final cheese product is either shipped to Agri-Mark or their customers. Raw whey collected from the Cheese Vats, DMC, Finishing Tables, and the Block Forming Towers is filtered through a Fine Saver before moving into the Clarifier. Excess solids from the clarifier are collected and disposed of. Raw whey continues to the Separator where cream and liquid are separated. The cream goes to the Cream Balance Tank where it is directed into the Batch Pasteurizer, then stored in the Cream Silos. The liquid continues to a different pasteurizer, followed by the Reverse Osmosis (RO) Unit. RO permeate flows to the Ultrafiltration (UF) Unit generating UF permeate (lactose) and whey protein concentrate (WPC). The WPC is collected in the WPC Silos. The product is either shipped to AgriMark, Middlebury facility, or other customers. The lactose continues to the Evaporator where water is removed. The concentrated lactose is stored in the Permeate Silos where it is hauled to Agri-Mark farms or their customers. Process wastewater generated from the manufacturing operation consists of rinsed water, milk and other milk products, bits of cheese, water extracted from whey ("cow water"), residuals from cleaning chemicals, as well as, cooling tower bleed and boiler blowdown. The pretreatment process begins when the waste streams commingle at the Receiving Lift Station. The wastewater is pumped through two (2) in-line strainers to the Equalization (EQ) Tank. From the EQ Tank, the wastewater is gravity feed into the pH Neutralization Tank with the addition of either sodium hydroxide (NaOH) or carbon dioxide (CO2) to pH adjust Page 3 of 7 Agri-Mark, Chateaugay, NY SIU Permit: C-009-89 Insp. Dates: September 19-20, 2023 the wastewater to within 6.7 - 6.9 Standard Units (SU). From the pH Neutralization Tank, the wastewater continues to the splitter box where it is distributed between the North and South Wet Wells. Pumps in the Wet Wells deliver the wastewater to their respective BioTowers with plastic media. The effluent and biomass from the Bio-Towers flow into the Rectangular Clarifier. Potassium permanganate (KMnO4) is added to the clarifier for odor control. The effluent from the clarifier overflows the V-Notch weirs and continues to the Parshall flume with an Ultrasonic flow sensor. The flow is monitored, then the pretreated effluent continues to the monitoring manhole before discharging into the Village of Chateaugay Sewer Collection System. Sludge from the Rectangular Clarifier is pumped into the Sludge Aeration Tank. From the Aeration Tank, the sludge is pumped into the spray trucks where it is land applied. Depending on sludge volume in the aeration tank, solids from the in-line strainers can be diverted to either the Sludge Aeration Tank or pumped into spray trucks to be land applied. 3.3 Facility Self-Monitoring Information Employees performed sample collection at the monitoring manhole. Composite samples are collected for 5-day Biochemical Oxygen Demand (BOD5) and Total Suspended Solids (TSS). On-site sample is collected and analyzed for pH (hydrogen ion). Endyne Environmental Laboratories provides Agri-Mark with sample containers for BOD5 and TSS. A courier from Endyne Environmental Laboratories transports the samples to the laboratory for analyses. 4.0 EPA SAMPLING/INSPECTION ACTIVITIES 4.1 Sampling Activities An ISCO automatic composite sampler was programmed to take 96 sample aliquots during the 24-hour sampling event at the monitoring manhole. A 24-hour composite sample was collected and analyzed for BOD5, and TSS. Grab sample was collected for Total Petroleum Hydrocarbons (TPH). In addition, on-site grab samples were collected and analyzed for pH and Temperature. All sample containers, preservation techniques and holding times were in accordance with USEPA requirements specified in 40 CFR Part 136. Signed and dated custody seal tape was placed across the lids and along the sides of the sample containers. The custody sealed sample containers were placed inside plastic sample bags and sealed. All samples were transported on ice to the USEPA Laboratory in Edison, New Jersey for analyses. Flow monitoring data were obtained from Agri-Mark instrumentation which was last calibrated on November 09, 2022. Split samples were collected and given to the facility representative.

Dates: September 19-20, 2023 6.1 Sampling Result Findings The EPA analytical results obtained during this inspection are within the acceptable limits. 6.2 Inspection Findings In addition to the analytical data, an inspection of the facility operation was conducted as discussed in Section 4.2 above. During the inspection, the following observations were noted which may contravene the requirements of the permit or the applicable regulations: 6.2.1 The approaching flow to the Parshall flume is turbulence. As a result, the Ultrasonic flow sensor is recording high flow. According to the ISCO Open Channel Flow Measurement Handbook, Fifth Edition, Page 73 of Chapter 4: Flumes, it states, "The approaching flow should enter the converging section reasonably well distributed across the entrance width, and the flowlines should be essentially parallel to the flume centerline. Surges and waves of any appreciable size should be eliminated. Also, the flow at the flume entrance should be free of "white" water and free from turbulence in the form of visible surface boils." Furthermore, Section 10.1(b) - Disposal System Operation and Daily Quality Control in Part - II General Condition of the SIU Discharge Permit, it states, "The permittee shall at all times, properly operate and maintain all facilities and system control (and related appurtenances) which are installed or used by the permitted to achieve compliance with the conditions of this permit..." 6.2.2 The sampling assemblage consists of the composite sample container, sampling tube, and sampling probe was observed to be dirty and/or contains algal growth. In addition, the sampling probe was observed covered with accumulated growth when raised above the discharging flow. It also felt the sampling probe was resting at the bottom of the monitoring manhole when it was lower back in. At any point in the sampling event and/or during the purging cycle, dirt and/or algal growth could potentially become dislodged and be part of the sample. Hence, the analytical result could be bias high. The sampling assemblage should be clean and/or replaced. Furthermore, the sampling probe should be positioned in the middle of the flow at mid-depth. According to Section 9.1(b) - Monitoring, Recording, and Reporting in Part - II General Condition of the SIU Discharge Permit, it states, "Samples and measurements taken to meet monitoring requirements specified in this permit shall be representative of the quantity and character of the monitored discharge...." Furthermore 40 CFR Part 403.12(b)(5)(ii) of the General Pretreatment Regulations for Existing and New Sources of Pollution, it states, " In addition, the User shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the Standard or Control Authority) of regulated pollutants in the Discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations...." Page 6 of 7 Agri-Mark, Chateaugay, NY SIU Permit: C-009-89 Insp. Dates: September 19-20, 2023 6.2.3 The facility starts pH calibration with the 7-buffer solution, followed by the 4buffer solution, then finally the 10-buffer solution. According to the "Monitoring, Recording and Reporting" Section of the SIU permit, it states, " Monitoring must be conducted according to test procedures approved under 40 CFR Pat 136 unless otherwise specified in this permit." Furthermore, 40 CFR Part 403.12(b)(5)(v) states, "Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR part 136 and amendments thereto." 6.2.4 No temperature control was observed in the composite sample refrigerator. It is necessary to maintain preservation of the composite sample during the sampling event. According to 40 CFR Part 136 Table II - Required Containers, Preservation Techniques, and Holding Times under footnote #2, it states, " Except where noted in this Table II and the method for the parameter, preserve each grab sample within 15 minutes of collection. For a composite sample collected with an automated sample (e.g., using a 24-hour composite sample; see 40 CFR 122.21(g)(7)(i) or 40 CFR part 403, appendix E), refrigerate the sample at 6 C during collection unless specified otherwise in this Table II or in the method(s)." 6.2.5 During the DMR data review for October 2022 and March 2023, it was noted that the 5-Day Biochemical Oxygen Demand (BOD5) samples exceeded the holding time. According to 40 CFR Part 403.12(b)(5)(v), it states, " Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR part 136 and amendments thereto." Furthermore, 40 CFR Part 136 Table II - Required Containers, Preservation Techniques, and Holding Times, the maximum holding time for BOD5 is 48 hours. 7.0 ATTACHMENTS Attachment #1.
