Published by U.S. Environmental Protection Agency, Office of Chemical Safety and Pollution Prevention | U.S. Environmental Protection Agency | Catalog Last Checked: May 06, 2026 at 12:33 AM | Dataset Last Updated: January 09, 2020 at 12:00 AM
This map service shows point locations for facilities that submitted TRI reports to EPA during the most recent reporting year. EPA's Locational Reference Table is used for the facility’s latitude and longitude coordinates. Icons on the map are relatively sized based on the sum of all chemical quantities reported as released. The pop-up presents TRI data including facility name, address, industry sector, and total on-site and off-site release amounts as well as identifiers for TRI and FRS programs and a link to a more detailed TRI report. The data refreshes biannually. For more information, refere to the TRI Program Webpages, https://www.epa.gov/toxics-release-inventory-tri-program.
