Victoria Nelson, Environmental Engineer 2. Eleanor Kane, Environmental Engineer Other Attendees: 1. Robert Brott, Winpak, Plant Manager 2. Julia Stover, Winpak, Process Engineer Contact Email Address: Robert.Brott@winpak.com; Julia.Stover@winpak.com Purpose of Inspection: To assess compliance with the Clean Air Act and the facility's operating permit Facility Type: Foil and film printing Arrival Time: 1:30 PM Central Time Departure Time: 4:00 PM Central Time Inspection Type: ~ Unannounced Inspection D Announced Inspection OPE.NIN~~-G- CONFERENCE~ ~ Credentials Presented ~ CBI warning to facility provided The following information was obtained verbally from the attendees unless otherwise noted. Process Description: Winpak receives inks, solvents, and aluminum foil with a heat seal as raw materials. Winpak operates three flexographic presses that print designs on foil lids for plastic containers. Printing is done by coating etched plates vvith ink and pressing onto foil. Plates are photosensitive sleeves with the desired design imprinted in the plating room. The plating room is equipped with a solvent still to aid plate imaging. Custom color inks are mixed in the ink room. Once printed, lids are cured in curing ovens and then punched out of foil rolls on die cutters and shipped to customers. Each of the three presses are housed in a permanent total enclosure (PTE) that is continuously monitored for differential pressure. The PTE and the plating room are exhausted to a regenerative thermal oxidizer (RTO). Staff Interview: The facility operates 24 hours a day for six or seven days out of each week and has 193 employees. The three presses are interlocked with the RTO. In 2018, vVinpak resolved an enforcement action v.~th the Illinois Environmental Protection Agency (IEPA), requiring them to obtain and operate pursuant to a new construction permit applying Best Available Control Technology (BACT). TOUR INFORMATION EPA toured the facility: Yes Data Collected and Observations: EPA inspectors toured the press room, ink room, plating room, and cutting operations. In the ink room, EPA observed ink mixing and found an open inactive drum containing ethyl acetate. The ink room is not exhausted to the RTO. Photos and/or Videos: were taken during the inspection. EPA collected three recordings with the FLIR optical gas imaging camera to observe potential uncontrolled emissions ofVOCs. Field Measurements: were not taken during this inspection.
