About TRI Data

Data as of 2023 reporting year. Source: U.S. Environmental Protection Agency (EPA) Toxic Release Inventory.

Data comes from the EPA Toxic Release Inventory (TRI) program. Facilities that manufacture, process, or otherwise use listed toxic chemicals above threshold amounts are required to report annually to the EPA.

Release quantities are self-reported by the facility and may represent estimates rather than exact measurements. "Total releases" includes releases to air, water, land, and off-site transfers for disposal. Quantities shown here are aggregated across all available reporting years.

PlainEnviro presents this data without advocacy framing. The presence of a facility in the TRI database does not by itself indicate a health risk. For site-specific health questions, consult your local environmental or health agency.
