• Quarter 3 stack monitoring and fugitive emissions results received by IEPA
• Vantage within permitted emission cap

The Illinois Environmental Protection Agency (IEPA) has updated its website to include the 2025 Q3 data related to Vantage’s permit. The results indicate Vantage has released 33.95 pounds (30.86% of permitted annual total) of EtO cumulatively year-to-date, of which 26.84 pounds (44.74% of permitted annual total) were fugitive emissions. Public Act 101-0023 and Vantage’s Construction Permit limit the facility to 110 pounds of emissions annually of which no more than 60 pounds can be fugitive emissions. The Q3 submission noted eleven leaking components, out of over 740 total components monitored, during the three-month period.  The components were repaired.

The third quarter report is now available on the IEPA website here: vantage-construction-118560-permit-Q3-2025.pdf
