The two EPA inspectors, one IEPA inspector, and two MWRD staff will be collectively referred to as the inspection team. The inspection team presented their credentials to staff at the security building who contacted Facility representative Tony Massa. After Mr. Massa arrived, the inspection team presented their credentials to him and informed him that this was an EPA inspection to determine compliance with the Clean Water Act (CWA), the National Pollutant Discharge Elimination System (NPDES) program, and National Pretreatment Standards. The inspection was conducted under the authority of the CWA NPDES program and Section 308 of the CWA. The table above identifies the attendees who participated in the inspection. This report is based on information supplied by Facility representatives, observations made by the EPA inspectors, and records and reports maintained by the permittee, MWRD, and EPA. These include the following: direct observations made by the EPA inspectors, photographs taken by EPA inspectors, and verbal or written statements made or supplied by Facility representatives (the permittee) during or subsequent to the onsite inspection, and materials, processes, data, photographs, or documents shown, demonstrated, or submitted to the EPA inspectors by Facility representatives during or subsequent to the on-site inspection. In addition, information gathered prior to or subsequent to the inspection from a review of EPA, MWRD, and public records may be included in this report. During the opening conference, facility representatives were asked if they considered any information confidential business information (CBI). Mr. Massa stated that no information was considered CBI by the Facility. Background Information Prior to the inspection, EPA inspectors confirmed the following facility information: Process wastewater generated at the Facility is covered by MWRD Discharge Authorization No. 26573-3 (Permit). The Permit places pretreatment program prohibited discharges and local limits effluent requirements on wastewater discharged to the collection system. The effective date of the Permit is April 26, 2018, and the Permit is scheduled to expire on April 25, 2023. The Facility is classified as a Significant Industrial User (SIU) by MWRD, which is an approved Control Authority under the NPDES program. The MWRD collection system that the Facility discharges to is a combined sewer, meaning it conveys both wastewater and stormwater. The Facility does not have a stormwater permit. MWRD personnel collect compliance samples from the Facility's Outfalls twice per year. Before the inspection, EPA representatives reviewed MWRD Facility compliance sample data from January 1, 2020 to June 1, 2022. The Facility did not have any documented effluent limit exceedances during this time period. Neither the Facility nor MWRD monitors for lower/upper explosive limits (LEL/UEL) in the Facility collection system or at its Outfalls. SECTION II - FACILITY INSPECTION Opening Conference After the inspection team presented their credentials to Mr. Massa, he escorted the team to Engineering, Maintenance, Purchasing, and Production building. The inspection team began their opening conference at Page 3 of 47 Vantage Oleochemicals June 9, 2022 approximately 9:25AM. Mr. Massa was present for the entire opening conference and Mr. Slaasted was present from approximately 9:45AM to 10:30AM. According to Mr. Massa, the Facility produces a variety of fatty acid and glycerin products, including: vegetable Kosher glycerin, non-Kosher glycerin, oleic acid, tallow fatty acid, separated stearic acid, hydrogenated tallow fatty acid, high purity stearic acid, and distilled vegetable fatty acid. Mr. Massa reported that the North American Industrial Classification System (NAICS) code for the Facility is 32519. He also provided documentation that in 2021 the Facility produced 24,738 tons of non-Kosher glycerin, 21,498 tons of vegetable Kosher glycerin, and 202,632 tons of fatty acid products. The Facility uses a variety of non-food grade feed stocks including animal fats and vegetable oils such as soy oil, canola oil and coconut oil. The type of feed stock and its source are regularly changed based on market price and availability. Feed stocks arrive at the Facility via rail cars and truck. Final products also leave the Facility via rail cars and trucks. Mr. Massa stated that the site where the Facility is located has historically been utilized to process animal byproducts but that since the 1950s the Facility has manufactured glycerin products. Mr. Massa also explained that the Facility underwent major upgrades in approximately 1987 but the core operations have remained the same. The Facility began operating under the name Vantage Oleochemicals in approximately 2009. The Facility operates 24 hours per day, 7 days per week. One day per year the Facility halts operations for annual maintenance activities. Mr. Massa stated the 2022 annual maintenance shutdown is scheduled for July 11th. The Facility has approximately 130 employees. Mr. Massa explained that all of the process wastewater and the majority of the stormwater generated at the Facility is treated on site before it is discharged to the MWRD collection system. A wastewater treatment system diagram was provided to the inspection team (Appendix 2). Additional information about the wastewater treatment system is provided in the Facility Walk Through section of this inspection report. The Facility stores hydrochloric acid on site for regenerating cation exchange columns for the water softening system, sodium hydroxide for saponification and pH adjustment within the wastewater treatment system, and phosphoric acid for pH adjustment in the wet scrubbers. The opening conference concluded at approximately 11:00AM. Sampling Following the opening conference, the inspection team began to collect wastewater samples at approximately 11:15 AM. The Facility has four permitted Outfalls; 1A, 1B, 1C, and 1D. Each outfall discharges to the MWRD collection system that runs along South Racine Avenue on the Facility's east side. Outfall 1A flows east approximately 15 feet to Manhole D located in South Racine Avenue. Manhole D is located within the MWRD collection system. Per the Facility's Permit, and observations made during the inspection, the Outfalls have the following contributing flows: Outfall 1A - Treated process effluent, treated stormwater, and untreated stormwater Outfall 2A - Sanitary wastewater, boiler blowdown, and untreated stormwater Page 4 of 47 Vantage Oleochemicals June 9, 2022 Outfall 3A - Sanitary wastewater and untreated stormwater Outfall 4A - Sanitary wastewater and untreated stormwater Additional information regarding sampling is provided in Section III. Wastewater analytical results are provided in Appendix 4. Below is a table of the observations made at each Outfall during sample collection. Gas measurements were taken using a MSA Altair 5x owned by MWRD. Sampling Location 1A 2A 3A 4A Manhole D Flowing Yes Yes Yes No Yes Observations ISCO 4210 flow meter = 239 gallon/min, Strong chemical odor, Wastewater = 42, pH = 6, Maximum Carbon Monoxide reading = 98 ppm. Flow = ~1 gallon/min, Wastewater = 19, pH = 7. Flow = ~1 gallon/min, Wastewater = 19, pH = 7, Maximum carbon monoxide measurement = 77 ppm, Maximum oxygen measurement = 21.3%. Not flowing, no measurements taken with gas meter. Flow = ~239 gallon/min, Strong chemical odor, Wastewater = 42, pH = 6, Maximum carbon monoxide measurement = 302 ppm, Maximum hydrogen sulfide measurement = 5 ppm. Facility Walk Through The inspection team concluded sampling at approximately 1:00 PM. The team took a short lunch break and began the Facility walk through at approximately 1:30 PM. Mr. Massa walked the inspection team through the Facility process lines. The general process flow involves the raw material passing through the splitters, hydrogenation, and then vacuum distillation. At each stage of the process the concentration of glycerin is increased. A Facility process flow diagram is provided in Appendix 3. After material is delivered to the Facility it is pumped to the raw material tank farm to be stored. Tallow raw material is sometimes passed through a filter to remove large impurities such as hair and bone. Not all tallow material passes through the filter before processing. The material is then sent to the splitting columns to undergo hydrolysis. Before hydrolysis, tallow fatty acids are separated into crude stearic acid and crude oleic acid with a filter press after chilling the mixture to around 50. The Facility uses a continuous hydrogenation process to saturate the fatty acids. This process adds gaseous hydrogen to the material and utilizes a nickel catalyst. According to Mr. Massa, the Facility historically utilized a batch hydrogenation process but converted to a continuous hydrogenation process in approximately 2002. Similarly, the Facility historically used a wet separation process but in approximately 2015 converted to a dry separation process. As part of the Kosher glycerin distillation process, salt is produced. The Facility considers the salt a waste product and it is disposed in a landfill as a non-hazardous waste. Mr. Massa estimated that 2-3 million pounds Page 5 of 47 Vantage Oleochemicals June 9, 2022 of salt are generated at the Facility per year. Additionally, fatty acid residuals are generated during the glycerin distillation process. The residuals from this process are a solid material that is also sent to a landfill for disposal as a non-hazardous waste. Mr. Massa explained that all the pipes within the Facility have a steam jacket or a different heating element around them to ensure the contents of the pipe are heated and flowing properly. The inspection team observed a steam hose placed in a drain within the Facility. Mr. Massa explained that when pipes get clogged, Facility personnel can inject steam to heat the blockage and restore flow. Additionally, there are stream traps throughout the Facility that collect steam condensate and discharge it to the Facility's collection system for treatment. Mr. Massa also explained that between uses, pipes that connect tanks must be cleared to prevent cross contamination of different products. The pipes are blown out onto the ground within the secondary containment areas and allowed to flow to drains that direct the waste to the main catch basin for treatment. Similarly, when a sample is collected from the port attached to the bottom of tanks, operators will allow the port to flow onto the ground for a few seconds before the sample is collected. The Facility has multiple tank farms to store material. The air in the headspace of these tanks is collected and sent to a wet scrubber for odor control. The Facility has four wet scrubbers, the wastewater generated by the scrubbers is sent to the main catch basin for treatment. Wastewater is generated from a variety of sources, including: the steam condensation, pipe blowdown, sampling blowdown, and wet scrubbers described above as well as boiler blowdown, secondary containment stormwater, wash water, and cooling tower blowdown. All wastewater generated at the Facility flows to the main catch basin for treatment. Most of the stormwater from the Facility also flows to the main catch basin for treatment. There are some storm inlets located within the Facility that bypass treatment and flow directly to the MWRD collection system. Water flows from the main catch basin to Tank 163. From Tank 163 wastewater flows via gravity to the hydroskimmer. According to Mr. Massa, the hydroskimmer is approximately 15-20 feet deep and allows fats to separate from the wastewater. A fat recovery pump was installed within the hydroskimmer in early 2021 to allow for easier recovery of fat from the system. Following the hydroskimmer, the water is treated by a coagulant (aluminum chloride hydroxide), then 50% sodium hydroxide for pH adjustment, then a polymer (Kurifloc 4224) before it reaches the dissolved air floatation (DAF) system. The DAF system generates sludge that is stored in two 5,000 gallon tanks inside the DAF building. These tanks are emptied twice per week and the contents are hauled off site for solidification and stabilization or for biodigestion. Following the DAF system, the treated effluent is either recycled back to the hydroskimmer to maintain its water level or it is discharged through outfall 1A. A wastewater treatment diagram is provided in Appendix 2. Outfall 1A has a ISCO 4210 ultrasonic flow meter to measure effluent flows. This Outfall discharges an average of approximately 300,000 gallons per day during dry weather. The flow meter is calibrated annually by a contractor. Per the Facility's permit, compliance samples must be collected and analyzed twice annually. The sampling and analysis are conducted by a contractor on the Facility's behalf. Page 6 of 47 Vantage Oleochemicals June 9, 2022 Mr. Massa stated the DAF system was installed in the early 2000's to replace the use of the aeration pond located on site. The pond was observed by inspectors to still contain water, but Mr. Massa stated that the pond is completely fenced in and that it is no longer utilized in any way by the company. Mr. Massa also explained that the pond's only source of influent is stormwater and there are no outlets for the water. Mr. Massa explained that on Saturday, June 4, 2022 that Facility encountered two abnormal situations: The first was pH effluent violation from the dissolved air floatation (DAF) system. The Facility's permit authorizes wastewater to be discharged with a pH between 5.0 - 10.0. On this day, wastewater was discharged with a pH of 4.26. Upon discovering the violation, a Facility representative called MWRD to inform them of the situation. Mr. Massa explained that the recirculating pump for the sodium hydroxide used in the DAF system for pH adjustment was broken and the problem was resolved in approximately 75 minutes. The second situation was the leak in the wall of a hydrochloric acid tank within the Facility which was discovered on June 4, 2022. Mr. Massa explained that the leak was captured within the secondary containment and a contractor was hired to neutralize the acid. During the inspection, the team observed a contractor use a vac truck to load the neutralized waste and dispose of it in the main catch basin that leads to the wastewater treatment system. SECTION III - SAMPLING AND ANALYTICAL RESULTS Wastewater samples were collected from five locations during the inspection. Samples were analyzed for volatile organic compounds (VOCs) by the U.S EPA Region 5 Analytical Service Branch. Mr. Slaasted accompanied the inspection team while they sampled within the Facility, he did not accompany them to Manhole D. The inspection team offered split samples for each sample collected. Mr. Slaasted accepted split samples for sample location 1A but declined split samples for all other sample locations. Split samples were collected in the same manner as the samples analyzed by EPA. Sample were collected from the following locations: 1A: 2A: 3A: DAF: Manhole D: MWRD Discharge Authorization Sample Location 1A MWRD Discharge Authorization Sample Location 2A MWRD Discharge Authorization Sample Location 3A Effluent from the dissolved air floatation (DAF) treatment system First manhole in the MWRD collection system to receive water from sample location 1A Below is a summary of analytes that were detected in concentrations above 100 ug/L.

Unique Identifying No. TF-OB-001 Record Spent nickel catalysis is stored in large sacks outdoors. The sacks are not sealed and have potential expose to stormwater. TF-OB-002 There is a large crack in the south wall of the hydroskimmer. TF-OB-003 Water was observed bubbling out of a manhole immediately east of the DAF building. TF-OB-004 TF-OB-005 There is a large buildup of solidified stearic acid on the ground in the stearic acid loading area. One of the DAF effluent pH probes is due for calibration. TF-OB-006 TF-OB-007 One June 3, 2022, there was a pH effluent violation caused by the failure of the sodium hydroxide recirculating pump. On June 3, 2022, there was a leak of hydrochloric acid due to storage container failure. TF-OB-008 A steam hose was being used to break up a suspected solidified fat blockage in a drain. TF-OB-009 There were bubbles coming up through the water of the hydroskimmer. The source of these bubbles was not immediately clear. SECTION V - CLOSING CONFERENCE Closing Conference The inspection team held a closing conference with Facility personnel beginning at approximately 4:15PM. During the closing conference, inspectors discussed the observations and Areas of Concern identified during the inspection. Observations and Areas of Concern have not yet been evaluated for a formal compliance determination. The inspection team departed the Facility at approximately 4:45 PM.

Six samples were received by the Analytical Services Branch (ASB) on June 9, 2022 as work order (WO) 2206006, and were analyzed June 1st and 2nd for volatile organic compounds (VOCs) in batches B22F054 (screening only, not reported) and B22F058. All samples were refrigerated until analysis and met preservation (acidification) and hold time (14 days) requirements. The designated analyst for these samples, Kristen Leckrone, can be reached at (312) 353-9058. Analyst-in-training Emerita Quiamjot assisted with preparation of calibration standards and programming the initial instrument calibration sequence. Processing of all calibration files, completion of the associated processing method, and preparation and analysis of all continuing calibrations, batch quality control samples and client samples were performed by the designated analyst. Sample Analysis and Results. Sample preparation and analysis were performed on the EST Purge and Trap Autosampler and Concentrator System and GC/MS#11 instrument via ASB standard operating procedure (SOP) MS023, VOA in Water (Based on EPA Method SW-846:8260C), Version 8 as modified by Pen & Ink (P&I) 27389. Data review was performed according to the guidelines in ASB SOP MS037 v.5 as modified by P&Is 21549 and 28831. The data reported herein meets the requirements referenced in the referenced SOPs, except as discussed in the Quality Control section below. No additional client specifications different than or beyond those in the referenced SOPs were provided in the analytical request form "Vantage Olechemical, 4650 S. Racine, Chicago, IL, request date 6/1/22". The standard MS023 analyte list is reported. Although not requested, the by-request compounds acrolein, acrylonitrile, and methyl tert-butyl ether are reported as a courtesy, because acrolein was observed at significant levels in several samples. In addition to the standard list and by-request analytes, many peaks were observed in the chromatogram for samples 2206006-01, 2206006-04, and 2206006-06, which do not coincide with any MS023 analytes. Some of these peaks were much larger than any of the listed MS023 analytes. Tentatively identified compounds (TICs) are discussed in the TIC section of the QC narrative below. Quality Control. All quality control (QC) requirements were within ASB limits for the analytes or did not result in qualification of the data except as described below. Initial calibration. The lowest calibration point, 1 ug/L, was dropped for acrolein and acrylonitrile, which could only be calibrated from 2 ug/L to 100 ug/L, rather than from 1 - 100 ug/L for most other analytes (2 - 200 ug/L for 2-hexanone, see MRL section below). The shortened calibration for acrolein and acrylonitrile met initial calibration requirements for number of calibration levels and for linearity. Although calibrated, 2-chloroethyl vinyl ether is not reported because it is unstable in acidic solution. Analysis for this analyte requires collected of separate, unacidified samples. Calibration was verified via a 2nd-source initial calibration verification (ICV) standard. The ICV failed low for dichlorodifluoromethane and chloroethane. These analytes are qualified L, (ICV), low bias observed in the ICV, for all field and QC samples, including both detected and undetected results. The analytes acrolein, acrylonitrile, methyl tert-butyl ether, 2-butanone, 4-methyl-2-pentanone, and 2-hexanone are absent from the ICV mix, so calibration for these analytes is not subject to second-source verification. The accuracy of the low-level calibration was evaluated by reprocessing calibration points through the calibration equations at calibration level 2, which represents the method reporting limit (RL, 2 ug/ L for most compounds, 4 ug/L for 2-hexanone), and at calibration level 1 (half the reporting limit, 1 ug/ L most analytes, 2 ug/L for hexanone).

No results, including blanks, are reported below 2 ug/ L for either of these analytes. Blanks. For most analytes, blanks were evaluated down to the method detection limit (MDL). No analytes were detected down to this level in any method blanks. For acrolein and acrylonitrile, blanks could not be evaluated below the MRL due to the shortened calibration.. For these two analytes, no blanks were detected down to the 2 ug/ L reporting limit. All sample results for these analytes met blank criteria that detected sample results exceed 5x the highest measured blank. No blank qualifiers were required for any analytes. Blank spike/blank spike duplicate (-BS/BSD). Acrolein was also recovered below acceptance limits in batch B22F054, an unreported screening batch for work order 2206006, but multiple samples in the screening batch showed significant hits for this compound. As an on-the-spot corrective action, a new ampoule of acrolein was opened. (The ampoule also contained acrylonitrile, since both analytes are present together as a commercial mix, but performance in the prior solution was still in control). New spiking solutions and -BS/BSD control samples were prepared, including with all analytes (B22F054-BS1, -BSD1, and -BS3), and with only acrolein and acrylonitrile (B22F054-BS2, -BSD2, and -BS4), as simplified solutions prepared with minimal handling. Acceptable calibration of acrolein was established from the latter solutions (-BS2, -BSD2 and -BS4), so no qualification of acrolein was required for samples in batch B22F058. Dichlorodifluoromethane, chloromethane and vinyl chloride were recovered low in B22F058-BS1, -BSD1, and -BS3, and bromomethane was recovered low in B22F058-BSD1 and -BS3. These analytes are qualified L, LCS for all samples in the batch, including both detected and nondetected results. Chloroethane was recovered low in B22F058-BS3. Results are already qualified L, (ICV). An (LCS) descriptive qualifier is added to affected samples 2206006-01RE4 and -06RE5, which are the only injections bracketed by -BS3. Carbon disulfide was recovered above limits in B22F058-BS1 and -BSD1, but there is no impact to data because in was undetected in samples bracketed by these standards. Matrix Spike and Duplicate (MS and MSD). No sample or QC results, including the MS/MSD, are reported from batch B22F052, a 50x screening batch performed to identify the correct dilutions at which to analyze for each analyte. Although only one MS/MSD pair is required per batch, in batch B22F058, two MS/MSD pairs were performed due to the wide range of concentrations of analytes in the samples. One MS/MSD pair was prepared for the 20x bench dilution, and a second pair for the undiluted (1x) source. Each analyte is reported in the source and the MS/MSD of matching dilution. All analytes passed in the MS/MSDs for which they were on scale and reported, and no matrix qualifiers were required. Tentatively Identified Compounds (TICs). For samples 2206016-01, 2206016-04, and 2206016-06, , the total ion chromatograms were dominated by peaks that did not correspond to supported analytes in MS023, including many which were significantly larger than the supported compounds, surrogates and internal standards. Unidentified peaks in the total ion chromatogram were searched against the National Institute of Standards & Technology (NIST) spectral library, and the highest library matches were evaluated against TIC qualitative acceptance criteria in MS 023. The eleven most significant TICs were tentatively identified as acetaldehyde, 2-heptanone, 2-octanone, 1-octanol, 2-nonanone, 1-heptanol, 1-hexanol, 1-butanol, 2-decanone, 1-nonanol, and 2-octanol, in order of decreasing peak area. This is consistent with observations that the highest concentrations of MS023-supported analytes were also aldehydes (acrolein, 286 ug/L) and ketones (acetone, 2-butanone, 2-hexanone measured at 3110, 804, and 176 ug/L, respectively). Alcohols are not generally analyzed by VOA-8260 purge and trap methods, and no alcohols are included in the standard MS023 analyte list, so there are no listed alcohols against which to compare the magnitudes of the unlisted ones. Unsupported analytes cannot be reliably quantitated from the total ion chromatogram, however, the peak area of the eleven TICs named above ranged from 25 to 5 times the average area of the 50 ug/L internal standards. Based on their peak areas relative to those of the Report Name: 2206006 VOA - 8260 FINAL Jul 27 22 1636 Page 7 of 43 Water Division, WECA Region 5 77 West Jackson Boulevard Chicago IL, 60604 Environmental Protection Agency Region 5 US EPA Region 5 LSASD Analytical Services Branch 536 South Clark Street, Chicago, IL 60605 Phone:(312)353-8370 Fax:(312)886-2591 Project: Vantage Olechemical Project Number: [none] Project Manager: Andi Hodaj Reported: Jul-27-22 16:36 known 50 ug/L internal standards, a crude order-of-magnitude estimate is that these eleven compounds could be present in concentrations of hundreds to thousands of ug/L.
