EPA Facility Registry Service State Identifiers

The EPA Facility Registry Service (FRS) ER_STATE_ID dataset contains identifiers for U.S. facilities subject to environmental regulation. Managed by the U.S. Environmental Protection Agency, this dataset is classified as Mission Sensitive and Critical Infrastructure, restricting access to the EPA intranet. The most recent metadata update was recorded in April 2026.

Use Cases

• Cross-referencing facility identifiers for regulatory compliance checks across EPA programs.
• Geospatial mapping of regulated facilities for regional environmental impact analysis.
• Linking facility data to specific permits, cleanup actions, or contaminant reports using state IDs.

Strengths

• Data is maintained by the authoritative U.S. Environmental Protection Agency (EPA).
• Covers a national scope including states, territories, and the District of Columbia.
• Classified for internal use, indicating data is curated for mission-critical applications.

Limitations

• All concrete metrics (row count, file size, column names) are unavailable from the provided sources.
• Access is strictly restricted to the EPA intranet, preventing public or external researcher use.
• Metadata shows multiple update dates (March and April 2026), creating ambiguity about the true latest version.
