EPA Superfund Non-NPL Facility Locations and Identifiers

A subset of the EPA Facility Registry System containing integrated location and identification data for facilities linked to the CERCLIS non-NPL Superfund program. The data is maintained by the U.S. Environmental Protection Agency and was last updated in February 2026. It includes facilities across U.S. states and territories, focusing on sites not on the National Priorities List.

Use Cases

• Map facility locations to analyze geographic clusters of non-NPL Superfund sites for regional environmental risk assessment.
• Link facility identifiers from this registry to other EPA program systems for cross-program compliance and enforcement tracking.
• Analyze the distribution of non-NPL facilities by state and territory tags to prioritize cleanup resource allocation.

Strengths

• Data originates from the authoritative EPA Facility Registry System, which integrates records from multiple federal and state sources.
• Specifically focuses on the CERCLIS non-NPL subset, providing a targeted view of Superfund program facilities.
• Explicitly covers facilities across all U.S. states and multiple territories, as indicated by the provided tags.

Limitations

• The dataset is restricted to internal EPA use only and is inaccessible to the public via the described intranet services.
• Key quantitative details like row count, column names, and temporal coverage of the records are unavailable.
• Data is classified as Mission Sensitive and Critical Infrastructure, imposing significant access and usage barriers.
