EPA FRS ER_NAICS: Regulated Facility Registry for Critical Infrastructure

The EPA Facility Registry Service (FRS) ER_NAICS dataset contains information on facilities, sites, or places subject to U.S. environmental regulation or of environmental interest. The data is collected by the United States Environmental Protection Agency (USEPA) to support public health and environmental protection. The dataset was last updated on 2026-04-12 and is considered mission-sensitive and critical infrastructure information.

Use Cases

• Identify facilities of environmental interest based on EPA's regulatory scope.
• Analyze critical infrastructure sectors based on the NARA classification mentioned.
• Cross-reference facility information with other environmental datasets based on the registry nature.

Strengths

• Data is maintained by the authoritative U.S. Environmental Protection Agency.
• Dataset is explicitly classified as mission-sensitive and critical infrastructure, indicating high relevance for its intended use.
• Last update timestamp is precisely recorded as 2026-04-12 19:32:28.798417.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data access is restricted to the EPA intranet, severely limiting public usability.
