Reporting for TRI Facilities

Each year, certain industrial facilities submit Toxics Release Inventory (TRI) data to EPA. The data are due by July 1 and cover waste management activities that occurred during the previous calendar year. EPA makes these data publicly available.

Other Resources

Not all facilities need to report to the TRI Program. Review the TRI reporting requirements carefully to determine if your facility must report to TRI.

TRI Reporting Requirements

A facility must report if it meets all three TRI reporting criteria or is specifically required to report based on a determination by the EPA Administrator under EPCRA 313(b)(2).

Decision tree diagram that helps facilities determine if they are required to submit annual TRI data.

Facilities that meet all TRI reporting criteria must:

Submit a TRI Form R for each TRI-listed chemical it manufactures, processes, or otherwise uses in quantities above the reporting threshold. (Note: Facilities may be eligible to submit the shorter Form A if they meet certain criteria. See the TRI Reporting Forms and Instructions for details.)
Submit each TRI form to both EPA and the state in which the facility is located (or to the appropriate tribe, if located in Indian country).
Submit each reporting form using TRI-MEweb, EPA's online TRI reporting application.

Highlights of What's New for RY 2024

The changes below apply to RY 2024 TRI forms, which were due to EPA by July 1, 2025. For details, see the TRI Reporting Forms and Instructions.

TRI Reporting and EPCRA Tier II Reporting

TRI reporting is required under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA). Tier II reporting is required under Section 312 of EPCRA. TRI reporting requirements are separate and distinct from Tier II reporting requirements. Submitting TRI reporting forms does not fulfill a facility's Tier II reporting requirements, or vice versa. For more about what EPCRA requires, see the EPCRA factsheet or quick guide.

How Your Facility's Data Will be Used

The TRI data your facility submits are critically important and widely used—not only by EPA, but by public health and policy researchers, educators, local emergency planners, state technical assistance providers, community groups, prospective home buyers, and others.

EPA uses TRI data in many ways and for many purposes. These include:

assessing trends in chemical waste management,
evaluating industry progress in improving environmental performance,
informing pollution prevention technical assistance,
supporting chemical assessments under the Toxic Substances Control Act, and
supplementing data in the National Emissions Inventory.

The timely submission of accurate data by your facility enables all of these important uses, and more. To see examples of how TRI data submitted by facilities like yours are being used, visit the TRI Data Uses Catalog.

Annual TRI Data Collection, Publication, and Analysis Cycle

Deadline for facilities that meet TRI reporting requirements to submit reporting forms to EPA and the relevant state or tribe.
Preliminary, facility-level data for the previous calendar year are available in downloadable files on the TRI website and in the Envirofacts TRI searches.
The preliminary dataset is updated as additional reporting forms are processed. EPA conducts data quality checks.
EPA publishes the complete dataset and begins analyzing it to build the TRI National Analysis.
TRI Program publishes reporting instructions, updates training materials, and releases a new version of the TRI-MEweb reporting software. Facilities prepare and submit TRI forms covering chemical waste management and pollution prevention activities that occurred during the previous calendar year.
EPA publishes the TRI National Analysis, an in-depth look at the previous calendar year's TRI data.
