U.S. EPA Superfund Non-NPL Facility Registry

CERCLIS non-NPL sites represent a subset of hazardous waste locations tracked by the EPA's Superfund program. The U.S. Environmental Protection Agency maintains this registry, last updated in April 2026, integrating data from federal, state, and tribal sources. It contains location and identification details for uncontrolled or abandoned hazardous waste sites not on the National Priorities List.

Use Cases

• Analyze the spatial distribution of non-NPL Superfund facilities using geospatial coordinates.
• Cross-reference facility identification data from FRS with other EPA program systems for regulatory compliance tracking.
• Map potential environmental justice concerns by overlaying facility locations with demographic datasets.

Strengths

• Data is integrated from EPA's national program systems, state, and tribal master records, providing a centralized source.
• Maintained by the authoritative U.S. Environmental Protection Agency with a recent update in 2026.

Limitations

• The dataset is restricted to internal EPA use only and is not publicly accessible.
• Specific quantitative metrics like row count, column count, and temporal coverage are unknown.
