Note: Reporting year (RY) 2024 is the most recent TRI data available. Facilities reporting to TRI were required to submit their data to EPA by July 1 for the previous calendar year's activities. TRI Explorer is using the 2024 Dataset (released November 2025). This dataset includes revisions for the years 1988 to 2024 processed by EPA. Revisions submitted to EPA after this time are not reflected in TRI Explorer reports. TRI data may also be obtained through EPA Envirofacts.

Users of TRI information should be aware that TRI data reflect releases and other waste management activities of chemicals, not whether (or to what degree) the public has been exposed to those chemicals. TRI data, in conjunction with other information, can be used as a starting point in evaluating exposures that may result from releases and other waste management activities which involve toxic chemicals. The determination of potential risk depends upon many factors, including the toxicity of the chemical, the fate of the chemical, and the amount and duration of human or other exposure to the chemical after it is released.

Quantities of waste data are from Section 8 of the Form R, which is the standard TRI reporting form. These data are available beginning with the 1991 reporting year.

This report ranks the 100 largest facilities reporting in a particular waste quantity category (by default, the report ranks the top 100 facilities by total waste managed). By sorting on different waste quantity categories (e.g., recycle on-site, energe recovery on-site, etc.), TRI Explorer will generate a report ranking the top 100 facilities for the specific waste quantity category chosen. Note that the top 100 facilities ranked for a specific waste quantity category will change as the category changes (i.e., the 100 facilities ranked for recycling on-site is not necessarily the same 100 facilities for energy recovery on-site).

Note that if a facility name appears multiple times within the table above, the facility is a multi-establishment and submitted multiple forms for the chemical.

The facility may have reported multiple NAICS codes to TRI in the current reporting year. See the facility profile report by clicking on the facility name to see a list of all NAICS codes submitted to TRI for the current reporting year.

A decimal point, or "." denotes that the facility left that particular cell blank in its Form R submission (a zero in a cell denotes either that the facility reported "0" or "NA" in its Form R submission). "NA" in a cell denotes that the facility has submitted only Form A and thus the data for release, waste transfers or quantities of TRI chemicals in waste are not applicable. By submitting a Form A the facility has certified that its total annual reportable amount is less than 500 pounds, and that the facility does not manufacture, process, or otherwise use more than 1 million pounds of the toxic chemical.
