Toxics Release Inventory: Are you ready to report?
Every year at the beginning of July, industrial facilities across the nation can breathe a collective sigh of relief — their annual inventories of toxic chemicals are complete! To ensure that your facility can be part of that celebration (and avoid a chaotic rush to meet the deadline), now’s the perfect time to start preparing for the Toxics Release Inventory (TRI).
The Environmental Protection Agency’s (EPA’s) TRI program requires industrial facilities to report waste management data on certain toxic chemicals they manufacture, process, and use by July 1 each year. Is your facility ready to report? Here’s an overview of the TRI program to help you answer this question.
Who’s covered by TRI reporting?
Generally, TRI reporting applies if the facility:
- Is in a covered industry sector (40 CFR 372.23);
- Employs 10 or more full-time-equivalent employees; and
- Manufactures, processes, or otherwise uses a covered chemical or chemical category (372.65) in quantities above the threshold levels (372.25, .27, and .28) in a given year.
TRI tip: The TRI reporting year (RY) reflects the calendar year covered by the report, not the year in which you submit the report. For example, TRI reports for RY 2025 are due by July 1, 2026.
What’s covered by TRI reporting?
Facilities must submit the TRI Form R (or the streamlined Form A Certification Statement if eligible) for each TRI-listed chemical manufactured, processed, or used during the previous calendar year. The data covers chemical waste management activities (including releases to the environment) and any actions taken to reduce or prevent chemical waste.
Facilities usually report for each chemical:
- The quantities of releases (routine and accidental),
- Any releases caused by catastrophic or other one-time events,
- The maximum amount on-site during the year, and
- The amount contained in wastes managed on-site or transferred off-site.
What’s new for RY 2025?
The TRI reports for RY 2025 contain three differences from previous years:
- The de minimis level for anthracene was lowered from 1.0 percent to 0.1 percent. Anthracene’s Chemical Abstracts Service Registry Number (CASRN) is 120-12-7.
- More activity sub-use codes were added to the sub-use codes for “processing” and “otherwise use” activities.
- Nine per- and polyfluoroalkyl substances (PFAS) were added to the TRI chemical list:
| EPA registry name | CASRN |
|---|---|
| 6:2 fluorotelomer sulfonate acid | 27619-97-2 |
| 6:2 fluorotelomer sulfonate ammonium salt | 59587-39-2 |
| 6:2 fluorotelomer sulfonate anion | 425670-75-3 |
| 6:2 fluorotelomer sulfonate potassium salt | 59587-38-1 |
| 6:2 fluorotelomer sulfonate sodium salt | 27619-94-9 |
| Acetic acid, [(.gamma.-.omega.-perfluoro-C8-10-alkyl)thio] derivs., Bu esters | 3030471-22-5 |
| Ammonium perfluorodecanoate | 3108-42-7 |
| Perfluoro-3-methoxypropanoic acid | 377-73-1 |
| Sodium perfluorodecanoate | 3830-45-3 |
How are TRI reports submitted?
Facilities must submit TRI reports electronically to the TRI-MEweb application on EPA’s Central Data Exchange (CDX). Even if a facility uses its own software to prepare TRI forms, it must upload and submit the forms to TRI-MEweb.
TRI tip: To complete the submission process on TRI-MEweb, you need to assign one user the Preparer role and another user the Certifying Official role. Ensure both users have added TRI-MEweb to their CDX user accounts.
TRI reports must be submitted to both EPA and the state. If your facility’s state participates in the TRI Data Exchange (TDX), TRI-MEweb will automatically send your report to the state. If your facility’s state doesn’t participate, you must send a hard copy of the report to the TRI state contact.
TRI tip: Use EPA’s “TRI Data Exchange” webpage to determine whether your facility’s state participates in TDX. As of March 2026, all 50 states participate in TDX. The District of Columbia doesn’t participate.
More TRI tips
Keep these things in mind when preparing your TRI reports:
- You must submit a Form R (or Form A if eligible) for each TRI-listed chemical your facility manufactured, processed, or otherwise used above the threshold quantity.
- TRI data is publicized. If a chemical’s identity needs to be protected, you have to submit substantiation forms to claim the chemical identity as a trade secret. EPA must approve the claims. Further, for each chemical with a trade secret claim, you have to mail hard copies of the substantiation forms and the corresponding Form R (or Form A if eligible) to EPA and the state.
- EPA’s online GuideME platform offers comprehensive guidance for TRI reporting, including reporting forms and instructions, the TRI chemical list, and Q&As.
- Contact the state environmental agency directly to confirm the submission method. EPA’s “TRI State Contacts” webpage contains state contact information.
- Register your facility on CDX or ensure your facility’s CDX account is updated as soon as possible to avoid delays caused by technical issues.
Start preparing for TRI reporting now to give your facility plenty of time to gather data, complete the forms, and respond to unexpected issues that could arise. That way, your facility can breathe easily throughout the whole reporting season.
Key to remember: The submission deadline for TRI reporting is July 1, 2026. Make sure your facility is ready to report.
