The facility manufactures both grape juice (80%) and wine (20 %), producing approximately 2.5 million gallons per year. Kedem Winery is categorized under Standard Industrial Classification (SIC) Code: 2084 Wines, Brandy, And Brandy Spirits. The processing facility operates from 8am to 5pm, Sunday through Thursday. The facility employs 2 workers at the wastewater treatment plant and 10 workers at the Juice/Wine processing facility. 3.2 Process Information Kedem Winery utilizes well water for its manufacturing and sanitary systems. The sanitary and process wastewater is separately discharged. Wastewater from domestic usage is sent to a septic field separate from the wastewater treatment plant. The process wastewater and rainwater captured in the drainage system is directed to the on-site wastewater treatment plant and directly discharged to an unnamed tributary which flows to the Hudson River. The wastewater generated from the juice and wine production processes changes throughout the season. During the Pressing Season, which lasts roughly between mid-September through October, the facility receives grapes from New York suppliers. The trucks unload the grapes into a crusher/ stemmer where the stems are removed, and the grape skins are broken. The crushed grapes are mixed with enzymes. The crushed/ destemmed grapes continue to a screw press where the skins and seed can be pressed out. The pressed juice proceeds to a centrifuge to further remove the pomace (stems, skins, and seed residue). The pomace and stems are disposed of via landfill. The juice is pumped to the filter room in which it can be filtered/concentrated using either diatomaceous earth (DE) or ceramic membrane filters. The DE can cause disruptions to the wastewater treatment system and therefore a portion of the DE is removed and disposed of via landfill. Juice slurries from the filtering process is routed to the treatment system. The concentrated juice is pumped to a tank for pasteurization. Following pasteurization, the juice is held in storage tanks. The juice or wine may be stored for up to 12 months; during this time the juice is circulated through tanks, refiltered, settled, and pasteurized. When ready to bottle, the juice/wine is transported to Kedem's Bayonne, New Jersey facility. Equipment may be rinsed with water or throughly cleaned with water/ caustics. Floor drains throughout the facility capture wastewater and directs it to the wastewater treatment plant. The process water/ rainwater captured in the drainage system is directed to the wastewater treatment plant where it collects in an equalization pump pit (Photograph 1). From the equalization pump pit the wastewater is pumped to an equalization tank. The equalization Page 3 of 8 Kedem Winery NPDES Permit: NY0219011 Inspection Date: August 20, 2024 tank's aerators have not been in use therefore the equalization tank acts as a settling tank. Wastewater from the equalization tank is pumped through a fine screen (Photograph 2). The screened liquid solid excess is deposited into a collection bin and pumped to the equalization pump pit. The screened effluent continues through a microscreen (Photograph 3) further removing solids. The microscreen is maintained by periodic rinsing to prevent clogging. Rinsed water from the microscreen enters drains and is returned to the equalization pump pit. The screened filtrate flows in sequence through the activated sludge aeration tanks (Photograph 4). When needed, Phosphorous and Urea can be fed into the aeration tanks to promote microbial growth. From the aeration tank, the mixed liquid is directed in sequence through an Ultrafiltration Membrane filter system (photograph 5). The filtered effluent flows through an inline electromagnetic flow meter and into a collection tank. From the collection tank the effluent continues through a pvc pipe and is discharged at Outfall 001 (Photograph 6). Sludge from the aeration tanks is either wasted as Waste Activated Sludge (WAS) or returned as Returned Activated Sludge (RAS). Waste activated sludge from the aeration tanks is held in one of the two sludge holding tanks. Wasting is performed at regular intervals. Sludge from the holding tanks is regularly hauled by Earthcare to an offsite disposal location. 3.3 Facility Self-Monitoring Information Permit compliance sampling is preformed and collected by Singh Operational Services Inc. operators contracted by Kedem Winery. On-site samples are collected and analyzed for pH and dissolved oxygen. In coordination with the contract laboratory, Pace Analytical, located in Newburg, NY; grab samples are collected and analyzed for cBOD5, TSS, TKN, Ammonia (NH3) and settable solids. Samples are transferred into laboratory bottles supplied by Pace Analytical and delivered to the laboratory for analysis. In addition, Pace Analytical calculates the Ultimate Oxygen Demand. 4.0 EPA SAMPLING/INSPECTION ACTIVITIES 4.1 Sampling Activities Grab samples were collected and analyzed for, pH, settable solids, and dissolved oxygen. Additionally grab samples were collected for cBOD5, TSS, TNK, and NH3. All samples were collected directly from Outfall 001. All sample containers, preservation techniques and holding times were in accordance with USEPA requirements specified in 40 CFR Part 136. All samples were transported on ice to the USEPA Laboratory in Edison, New Jersey for analyses. Page 4 of 8 Kedem Winery NPDES Permit: NY0219011 Facility representatives provided Flow data. Inspection Date: August 20, 2024 Split samples were collected and given to the facility representative. 4.2 Inspection Activities A NPDES compliance sampling inspection was conducted on August 20th, 2024. The inspectors met with Ruven Herzog, Kedem Winery, Facility Manager; Matt DelCoco, the contract Operator for Kedem Winery employed by Singh Operational Services Inc., and the president/owner of Singh Operational Services Inc., Chandra Singh. Inspector's credentials were presented, and the facility representatives were informed that the purpose of the inspection, with supporting onsite activities, was to determine if the facility is in compliance with their NPDES permit NY0219011. On-site supporting activities consisted of collecting samples at the monitoring location, observing and evaluating the monitoring location, observing and evaluating the flow monitoring equipment, observing and evaluating the facility sampling equipment, reviewing and evaluating the facility's laboratory data and test procedures, touring the manufacturing operation to observe where process wastewater is generated, touring the On-site Wastewater Treatment System, and interviewing the facility's representatives. During the closing conference, the facility representatives were briefed on the inspection activities. On-site sample results and concerns observed during the inspection were communicated to the facility representatives. 5.0 ANALYTICAL RESULT Kedem Winery - Outfall 001 Inspection Dates: 08/20/2024 Parameter Flow pH Settleable Solids Dissolved Oxygen * Sample Type Continuous Grab Grab Grab Units Gpd SU mg/l mg/l Permit Limit 20,000 6.5-8.5 0.3 7.0 Ammonia * Grab mg/l 1.5 TKN Grab mg/l Monitor TSS Grab mg/l 45 lb/day 7.51 CBOD5 Grab mg/l Monitor UOD * Grab mg/l 50 lb/day 8.34 Notes: U = analyte was not detected at or above the reporting limit K = Result may be biased high.

The analytical result for dissolved oxygen from the two runs is an average of 5.05 mg/l. 6.2 Inspection Findings In addition to the sampling, an inspection of the facility operations was conducted as discussed in Section 4.2 above. During this inspection the following observations were noted which may contravene the requirements of the permit or the applicable regulations: 6.2.1 According to the facility representative the flow meter was last calibrated in June 2023. The flow meter should be calibrated at least once a year to ensure flow measurements are accurately recorded. According to 40 CFR Part 122.41(e) - Proper Operation and Maintenance, it states, "The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit." 6.2.2 According to the SPDES Permit, the mass loading calculation for TSS and UOD are in pounds per day (lbs./d). According to, NYSDEC DMR Manual for Completing the Discharge Monitoring Report for State Pollution Discharge Elimination System (SPDES) - 2002, daily is defined as "the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling.", "For pollutants expressed in units of mass loading (lbs/day or kg/day), the `daily discharge' is calculated as the total mass loading of the pollutant discharged over the day." TKN, CBOD5 and TSS are all collected as a singular grab sample and therefore the resulting mass loading calculation for these parameters is not indicative of a calendar day. 7.0 Attachments Attachment 1: USEPA Chain of Custody for Samples was submitted to the USEPA Region 2 Laboratory in Edison, NJ on August 20, 2024 Attachment 2: The USEPA Analytical Data Package was received on September 2, 2024 Attachment 3: Flow Schematic of Kedem Winery's Wastewater Treatment Plant Attachment 4: Kedem Winery Wastewater Treatment Plant Diagram Page 6 of 8 Kedem Winery NPDES Permit: NY0219011 Inspection Date: August 20, 2024 8.0 Photographs Photograph 1: The Equalization Pump Pit collects the facilities process water and storm water Photograph 2: The fine screen removes solids from the wastestream.
