Toxics Release Inventory (TRI) Program

2018 TRI Preliminary Dataset

The 2018 Toxics Release Inventory (TRI) preliminary dataset contains data about chemical releases, waste management and pollution prevention activities that took place during 2018 at more than 20,000 federal and industrial facilities across the country.

Dataset Status

  • Includes reporting forms processed as of:
    August 7, 2019
  • Estimated percentage complete: 99%
    (compared to the complete 2017 National Analysis dataset)
  • Email us a question or comment

The TRI preliminary dataset is available each July through September so the public can access the most recent TRI information prior to the annual publication of the TRI National Analysis in January.

The data are available via the "Get 2018 Data with Envirofacts" and "Download 2018 Data" tabs below.

Introduction

The 2018 TRI preliminary dataset consists of TRI data for 2018. 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 (for example, 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.

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 2018 dataset in October 2019, followed by the 2018 TRI National Analysis in January 2020.

Frequently Asked Questions

Is the 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 2018 dataset will be available in October 2019, and will be the basis for the 2018 TRI National Analysis.

Did EPA collect any different TRI data for the 2018 reporting year?

Yes, for Reporting Year 2018, EPA made several changes to the TRI reporting forms as part of the TRI Program’s recent Information Collection Request, including:

  • Facilities now use subcategories to describe activities when selecting certain processing and otherwise use activity categories. Specifically, the processing categories of “as a reactant” and “as a formulation component” now contain subcategories as do all otherwise use categories (i.e., “as a chemical processing aid”, “as a manufacturing aid,” and “ancillary or other use”).
  • When reporting on-site disposal data, a facility may indicate that on-site release or other disposal quantities that were reported were managed in waste rock piles and may provide the quantity of the chemical managed in such piles.
  • Reporting of transfers to POTWs now use transfer codes to more closely align with how transfers to other off-site locations are reported. Facilities will report quantities individually with waste management activities for each POTW.
  • A new barrier code can be used when a facility elects to indicate it is unable to conduct a source reduction activity due to a reduction not appearing to be technically feasible.
  • Additionally, the Form A Certification Statement now allows for a facility to provide optional information.

Can I access pollution prevention (P2) information reported to TRI in 2018?

P2 data reported by TRI facilities for 2018 can be found in Envirofacts and in the downloadable data files. In September 2019, we plan to update the TRI P2 Search Tool to include 2018 data. This tool allows you to access, visualize, and analyze TRI’s P2 data.

When will the 2018 TRI data be available in the other online TRI tools, such as TRI Explorer and myRTK?

We plan to update the other online TRI tools with the complete 2018 dataset later in 2019. 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 2018 data for a particular facility mean that the facility is out of compliance with TRI requirements?

No, the absence of 2018 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 2018. As in every reporting year, EPA undertakes many 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.

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.

Get 2018 Data with Envirofacts

  • TRI Reporting Form R Search - View a facility's TRI data on a copy of its Reporting Form R.
  • TRI Reporting Form R and Form A Download - Select and download data elements from the Reporting Form R and Form A.
  • TRI EZ Search - Create a report on a single subject area (e.g., "discharges to water") using a limited set of TRI data elements.
  • TRI Customized Search - Create a report on multiple subject areas using the most comprehensive set of TRI data elements.

Download 2018 Data

Please note that these downloadable files are recommended for experienced TRI data users due to the format of the files which may be viewed in Excel or another spreadsheet application:

  • Basic - Contains the most commonly requested data fields from the Reporting Form R and Form A.
  • Dioxin, Dioxin-Like Compounds and Toxic Equivalency - Includes the individually reported dioxin mass quantity data from the TRI Reporting Form R Schedule 1, with associated toxic equivalency data. Data are presented in .csv (comma-separated value) file format.
