UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION 5 77 WEST JACKSON BOULEVARD CHICAGO, ILLINOIS 60604 SUBJECT: FROM: THRU: TO: CLEAN AIR ACT INSPECTION REPORT Vantage Oleochemicals Inc., Chicago, IL Brianna Fenzl, Environmental Engineer AECAB (IL/IN) Nathan Frank, Section Supervisor AECAB (IL/IN) File BASIC INFORMATION Facility Name: Vantage Oleochemicals Inc. (Vantage) Facility Location: 4560 S Racine Avenue, Chicago, IL Date of Inspection: June 3, 2022 EPA Inspector(s): 1. Brianna Fenzl, Environmental Engineer 2. Karyn DeFranco, Physical Scientist Other Attendees: 1. Ted Flatebo, Environmental Engineer, US EPA WECAB 2. Andi Hodaj, Environmental Engineer, US EPA WECAB 3. Katherine Haile, Physical Scientist, US EPA ARD 4. Luke Toonen, Environmental Specialist, Metropolitan Water Reclamation District (MWRD) 5. Jenny Entwhistle, Environmental Specialist, Metropolitan Water Reclamation District (MWRD) Contact Email Address: Offsite Report Purpose of Inspection: Conduct Clean Air Act offsite monitoring of air emissions from manhole covers along Vantage wastewater stream discharge. Facility Type: Organic Chemical Manufacturing Facility Page 1 of 3 Regulations Central to Inspection: Facility FESOP permit; Illinois SIP including, but not limited to emission limits on the fatty acid plant; Facility construction permit; 40 C.F.R. Part 60 Subparts A, VVa, and NNN, including emission limits and monitoring requirements on the Luwa Glycerin Distillation (GD2) plant. Arrival Time: 11:26 AM Departure Time: 12:21 PM Inspection Type: Unannounced Inspection Announced Inspection OFFSITE MONITORING OBSERVATIONS Data Collected and Observations: Offsite monitoring was conducted outside of the Vantage's fenceline for air emissions along the wastewater stream outflow. "Manhole D" is the outlet of the Vantage's process wastewater discharge into the city sewer system adjacent to MWRD's onsite sampling point 1A. The 1A manhole cover inside the fenceline was open with equipment for sampling attached. Manhole D lid was hot to touch. MWRD removed the lid from Manhole D and stated the outflow from Vantage was lower than expected. The 4-Gas Detection Meter detected H2S at 4 ppm and CO at 20 ppm and 34 ppm. Photos and/or Videos: were not taken during the inspection. Field Measurements: were taken during this inspection. Toxic Vapor Analyzer (TVA) total hydrocarbon readings 4-Gas Detection Meter used to measure H2S and CO.
