According to the EPA Toxics Release Inventory, Ethylene Glycol (CAS 107-21-1) is disclosed by 1,971 Form R facilities totaling 96.5M lbs of reported releases. TRI pounds are self-reported disclosure totals, not a measured public-health risk score.
Ethylene Glycol (CAS 107-21-1) is a chemical tracked by the EPA Toxics Release Inventory (TRI) program under Section 313 of the Emergency Planning and Community Right-to-Know Act. The TRI requires industrial facilities above specified threshold quantities to disclose annual manufacturing, processing, and otherwise-used volumes, along with quantities released to air, water, land, and off-site transfers.
A carcinogen flag, when present on other chemicals in this database, reflects an assessment from EPA, IARC, or the National Toxicology Program rather than a TRI-specific determination. The largest individual disclosure in the current dataset comes from SAFETY-KLEEN SYSTEMS INC. in NV at 14.5M lbs.
TRI volumes are self-reported estimates, not measured stack emissions, and each pound counts equally regardless of chemical toxicity, so total pounds should not be equated with total risk. Inclusion of a chemical or facility in the TRI does not itself establish a health hazard; it documents the public right-to-know record. Consult EPA's IRIS (Integrated Risk Information System) and the Agency for Toxic Substances and Disease Registry for health-effect summaries.

Trend & Where It's Reported
Between 2019 and 2023, cumulative annual Ethylene Glycol releases across all reporting facilities increased by 83% (13.1M lbs → 23.9M lbs). Year-to-year swings reflect facility openings/closures and reporting changes as much as underlying activity.
Reporting for Ethylene Glycol is concentrated: Texas accounts for 29.4% of the reported total (366 facilities). Next: Nevada.
- Texas 28.4M lbs
- Nevada 17.8M lbs
- California 8.9M lbs
- Indiana 3.3M lbs
- Utah 3.1M lbs
Reporting for Ethylene Glycol is concentrated by industry: Hazardous Waste facilities account for 43.2% of the reported total (136 facilities). Next: Chemicals.

Health Information
Data comes from the EPA Toxic Release Inventory (TRI) program. Release quantities are self-reported by facilities and may represent estimates. The total shown aggregates reports across all facilities and reporting years.
PlainEnviro presents this data without advocacy framing. The presence of a chemical in the TRI database does not by itself indicate a health risk at current exposure levels. For health-related questions about specific chemical exposures, consult your local health agency or a toxicologist.
