Important Notes

• Quantities of dioxin and dioxin-like compounds are reported in grams, while all other chemicals are reported in pounds.
• TRI data only reflect TRI submissions received by EPA from facilities that meet TRI reporting requirements.
• Other facilities in your area may be releasing toxic chemicals but either were not required to report to the TRI Program or have not yet submitted their 2023 data.
• A TRI facility may be managing a toxic chemical for which the TRI reporting threshold was not exceeded, resulting in that chemical not being reported to the TRI Program.
