U.S. EPA Facility Registry for Superfund Non-NPL Sites

EPA's Facility Registry Service provides integrated location and identification data for facilities linked to the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) non-NPL sites. The dataset is a subset of the FRS, containing facilities once CERCLIS data is integrated, and is maintained by the U.S. Environmental Protection Agency. It was last updated in April 2026.

Use Cases

• Map facility locations and their proximity to environmental hazards using geospatial coordinates.
• Analyze the distribution of non-NPL Superfund facilities by state or region using geographic identifiers.
• Link facility records to other EPA program systems via integrated facility identification keys.
• Assess the scope of CERCLIS program coverage by analyzing facility types and registry status.

Strengths

• Data is integrated from EPA's national program systems, federal agencies, and state/tribal records, providing a centralized source.
• Dataset is designated as Mission Sensitive and Critical Infrastructure, indicating its authoritative role.

Limitations

• The dataset is restricted to internal EPA use only and is not publicly accessible, limiting external analysis.
• Specific data volume metrics such as row count, column count, and temporal coverage are unknown.
