Toxics Release Inventory (TRI) Program

TRI Data and Tools

The Toxics Release Inventory (TRI) Program tracks the industrial management of toxic chemicals that may pose a threat to human health and the environment. The data facilities submit to EPA are available here in multiple ways. For information about the steps EPA takes to optimize the quality of TRI data, see the TRI Data Quality webpage.

NOTICE: In early 2019, EPA learned that two TRI queries available in EPA’s Envirofacts database regarding off-site transfers of nonmetallic chemicals to Publicly Owned Treatment Works (POTWs) had not been updated with more accurate default assumptions regarding POTW treatment efficiencies. EPA updated the two queries within days of the discovery. Prior to the updates, between July 15, 2015, and March 20, 2019, it is possible that TRI data users accessing the 2014-2017 TRI datasets through Envirofacts queries that specifically related to off-site transfers to POTWs could have received data based on the previous default assumptions regarding POTW treatment efficiencies. Searches done during this time may be redone to make sure the results reflect the current default assumptions for non-metals sent off site to POTWs. For more information, please see the EPA Office of Inspector General's webpage about the issue.
