Toxics Release Inventory (TRI) Program

2016 TRI Preliminary Dataset

The Toxics Release Inventory (TRI) Program provides a preliminary dataset each July to give the public an opportunity to see the most recent TRI information prior to the annual publication of the TRI National Analysis in January.

The 2016 TRI preliminary dataset contains the most current TRI data available on toxic chemical releases and other waste management, and pollution prevention activities that occurred at industrial facilities during the 2016 calendar year.


The 2016 TRI preliminary dataset represents the most current TRI data available. Users should note that while the 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:
  • Determine if a particular facility has reported for the most recent calendar year;
  • Determine what chemicals a particular facility is using and releasing into the environment, or otherwise managing as waste; and
  • Find out if a particular facility initiated any pollution prevention activities in the most recent calendar year.

The agency will update the dataset several times in August and September based on information from facilities. EPA plans to publish the complete, quality-checked 2016 dataset in October, followed by the 2016 TRI National Analysis in January 2018.

Frequently Asked Questions

Is the 2016 preliminary dataset complete?

The dataset is not yet complete. We plan to update the dataset several times in response to late submissions and revisions submitted by facilities. The complete 2016 dataset will be available in October 2017, and will be the basis for the 2016 TRI National Analysis.

Did EPA collect any different TRI data for the 2016 reporting year?

Yes. This was the first year that 1-Bromopropane was subject to TRI reporting requirements.

Can I access pollution prevention (P2) information reported to TRI in 2016?

P2 data reported by TRI facilities for 2016 can be found in Envirofacts and the Downloadable Data Files. In September 2017, we plan to update the TRI P2 Search Tool to include 2016 data. This tool allows you to access, visualize, and analyze TRI’s P2 data.

When will the 2016 TRI data be available in other online TRI tools, such as TRI Explorer and myRTK?

We plan to update the TRI tools later this year, beginning with TRI Explorer in September. An announcement about the availability of these updated tools will appear on the TRI homepage and TRI email bulletin subscribers will also be notified via email.

Does the absence of 2016 data for a particular facility mean that the facility is out of compliance with TRI requirements?

The absence of 2016 data for a facility is not necessarily an indication that the facility is out of compliance. The facility's TRI reporting forms may still be undergoing processing, or the facility may not have met TRI reporting thresholds and therefore was not required to report for 2016. As in every reporting year, EPA undertakes a number of activities to identify facilities that are not compliant with TRI reporting requirements, and to verify the quality of the data received. This process is ongoing. When necessary, EPA's Office of Enforcement and Compliance Assurance may take action.

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 high-quality data. 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 expected to submit a revised form.
