2023 TRI Preliminary Dataset

The 2023 Toxics Release Inventory (TRI) preliminary dataset contains data about chemical releases, waste management and pollution prevention activities that took place during calendar year 2023 at more than 20,000 federal and industrial facilities across the country.

The TRI preliminary dataset is available each July through September, giving the public access to the most recent TRI information, prior to EPA finalizing the National Analysis dataset in October. EPA publishes the National Analysis report, based on the October dataset, early the following calendar year.

Introduction

Users should note that while these preliminary data have undergone the basic data quality checks included in the online TRI reporting software, they have not undergone the complete TRI data quality process. In addition, EPA does not aggregate or summarize these data, or offer any analysis or interpretation of them.

You can use the TRI preliminary dataset to:

Identify how many TRI facilities operate in a certain geographic area (e.g., a ZIP code),
Identify which chemicals are being managed by TRI facilities and in what quantities, and
Find out if a particular facility initiated any pollution prevention activities in the most recent calendar year.

Frequently Asked Questions

Is the preliminary dataset complete?

No, the preliminary dataset is not complete. EPA will update the preliminary dataset several times during the summer in response to late submissions and revisions submitted by facilities. The complete quality-checked 2023 dataset will be available in October 2024, and will be the basis for the 2023 TRI National Analysis.

Did EPA collect any different TRI data for the 2023 reporting year?

Yes, for 2023:

Nine per- and polyfluoroalkyl substances (PFAS) were added to the TRI chemical list, per the requirements of the National Defense Authorization Act (NDAA). Facilities were required to report on these chemicals for calendar year 2023 if TRI reporting requirements were met.
Twelve chemicals were added to the TRI chemical list, including one persistent, bioaccumulative, and toxic (PBT) chemical.
For the first time, facilities were required to report their foreign parent company, if applicable.

Can I access pollution prevention (P2) information reported to TRI in 2023?

P2 data reported by TRI facilities for 2023 can be found in the TRI Envirofacts queries (see list and links below) and in the downloadable data files. In October 2024, EPA plans to update the TRI P2 Search Tool to include 2023 data. This tool allows you to access, visualize, and analyze TRI’s P2 data.

When will the 2023 TRI data be available in the other online TRI tools, such as TRI Explorer and the TRI Toxics Tracker?

EPA plans to update the other online TRI tools with the 2023 dataset in October 2024. An announcement about the availability of these updated tools will appear on the TRI homepage and TRI listserv subscribers will also be notified via email.

Does the absence of 2023 data for a particular facility mean that the facility is out of compliance with TRI requirements?

No, the absence of 2023 data for a facility is not necessarily an indication that the facility is out of compliance. The facility's TRI forms may still be undergoing processing, or the facility may not have met TRI reporting thresholds and therefore wasn't required to report for 2023. As in every reporting year, EPA undertakes many activities to identify facilities that may not have been compliant with TRI reporting requirements, and issues with data quality. This process is ongoing.

Have any data quality checks been performed on the data?

Facilities use online software called TRI-MEweb to submit TRI data. TRI-MEweb includes many automated data quality checks that help facilities catch common mistakes and submit data of optimal quality. EPA is now conducting additional data quality checks on submitted data. If EPA or a facility detect an error on a submitted TRI reporting form, the facility is required to submit a revised form.

What else should I know?

Note that TRI data only reflect 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. In addition, 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.
