Note: Reporting year (RY) 2021 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 an updated data set (released to the public in September 2022). This dataset includes revisions for the years 1988 to 2021 processed by EPA, after the National Analysis Dataset was released. 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 TRI Chemicals in Waste from Section 8, Column B (Recycled On-site (8.4), Recycled Off-site (8.5), Energy Recovery On-site (8.2), Energy Recovery Off-site (8.3), Treated On-site (8.6), Treated Off-site (8.7), Total on-site disposal to Class I Underground Injection Wells, RCRA Subtitle C Landfills, and other Landfills (8.1A), Total other on-site disposal or other releases (8.1B), Total off-site disposal to Class I Underground Injection Wells, RCRA Subtitle C Landfills, and other Landfills (8.1C), Total other off-site disposal or other releases (8.1D), Total Quantity Disposed of or Otherwise Released On- and Off-site (8.1)), and Non-production-related waste managed from Section 8.8.

Beginning with reporting year 2003 Part II section 8.1 was replaced with 8.1A, 8.1B, 8.1C, and 8.1D. The new columns are included to facilitate trends analysis.

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.

A decimal point, or "." denotes the following: if a decimal point is reported across an entire row, the facility submitted a Form A (i.e., the facility certified that its total annual reportable amount is less than 500 pounds, and does not manufacture, process, or otherwise use more than 1 million pounds); or if a decimal point is reported in a single column, 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).
