EPA Toxic Release Inventory Facility Locations

Over 650 toxic chemicals tracked by the U.S. Environmental Protection Agency's annual Toxic Release Inventory program are linked to regulated facility locations. This dataset integrates facility identification and geospatial data from the EPA's Facility Registry System for TRI-reporting sites. The data was last updated by the EPA in April 2026.

Use Cases

• Map facility locations using geospatial coordinates to analyze regional clusters of toxic chemical releases.
• Link TRI-reporting facilities to other EPA regulatory programs using integrated facility identification keys.
• Analyze trends in waste management and pollution prevention activities reported annually by covered industry groups.

Strengths

• Integrates data from multiple EPA national program systems and state/tribal records
• Covers facilities reporting on more than 650 toxic chemicals

Limitations

• Data access is restricted to EPA intranet only, limiting external use
• Specific row counts and temporal coverage range are not publicly documented
