U.S. Toxic Release Inventory Facility Locations and Attributes

Over 650 toxic chemicals are tracked in this subset of the EPA Facility Registry Service, linking facilities subject to the Toxic Release Inventory program. The U.S. Environmental Protection Agency integrates and verifies data from national systems, state records, and tribal sources to create a single authoritative source. This dataset provides geospatial location and identification for facilities that report on chemical use, manufacturing, treatment, transportation, release, and pollution prevention activities.

Use Cases

• Map facility locations and analyze spatial clusters of toxic chemical releases using geospatial coordinates.
• Analyze trends in reported chemical usage, waste management, and pollution prevention activities by facility over time.
• Link facility identification codes to other EPA regulatory datasets for cross-system environmental compliance analysis.
• Assess the distribution of facilities subject to TRI reporting requirements across different industry groups or federal entities.

Strengths

• Integrates data from multiple authoritative sources including EPA national systems and state/tribal records.
• Focuses on facilities reporting on a specific inventory of over 650 toxic chemicals.
• Provides a centrally managed, verified source for facility identification and geolocation.

Limitations

• Specific row count, column details, and sample size are not provided in the source description.
• Temporal coverage and update frequency for the integrated TRI-FRS link are not specified.
• Potential for geographic bias based on the reporting requirements and coverage of the underlying TRI program.
