Toxics Release Inventory (TRI) Program
Previous Years' TRI Basic Plus Data Files
The downloadable TRI Basic Plus Data files have been updated to include the most recent TRI data revisions received by EPA. These include some significant changes that affect the totals published in the 2010 TRI National Analysis. With the revisions, total releases and other disposal for 2010 were 3.85 billion pounds, a 13.4% increase from 2009.
EPA has been collecting TRI data since 1987. To view or download National data files from any previous TRI reporting year, click on the TRI reporting year from the options below. These files are a set of seven files that collectively contain all the data submitted on the TRI Reporting Form R or Form A Certification Statement by facilities in a selected state.
Files available here are .txt files bundled into a .zip format, see the TRI Basic Plus Data File Documentation v10 (222pp, 1019K, About PDF ) for a detailed description of the data fields contained in these files. Note that quantities of dioxin and dioxin-like compounds are reported in grams; all other chemicals are reported in pounds.
