EPA Facility Registry Service: U.S. Environmental Sites and Programs

The U.S. Environmental Protection Agency's Facility Registry Service provides location and identification data for facilities subject to environmental regulations or of environmental interest. It integrates data from over 15 EPA national program systems, including the Toxic Release Inventory (TRI), Superfund (SEMS), and the National Pollutant Discharge Elimination System (NPDES). The dataset was last updated on 2026-04-14.

Use Cases

• Mapping the geographic distribution of hazardous waste sites based on the Superfund (SEMS) program data.
• Analyzing industrial sources of air pollution based on integration with the Air Facility System (AFS) and ICIS-AIR.
• Identifying facilities reporting toxic chemical releases based on linkage to the Toxic Release Inventory (TRI).
• Studying compliance and enforcement patterns using data from the Integrated Compliance Information System (ICIS).
• Assessing greenhouse gas emissions from large stationary sources based on the Electronic Greenhouse Gas Reporting Tool (E-GGRT) linkage.

Strengths

• Integrates facility data from over 15 distinct EPA national program systems and other federal agencies.
• Uses vigorous verification and data management procedures to provide a single authoritative source.
• Includes geospatial location data for facilities, enabling mapping and spatial analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
