How this service works
EPA Facility Registry Service (FRS) — every regulated facility known to the EPA across all programs (RCRA hazardous waste, NPDES water discharge, SDWA drinking water, TRI toxic release, CAA Clean Air, Superfund, etc.). Filter by state (required), facility name prefix, and EPA program acronym. Each record includes registry ID, primary name, address, city/state/county/zip, EPA region, program system + ID, source-of-data system. Public-domain US government records.
Output
A paginated list of EPA-regulated facilities matching the query, each record containing: registry ID, primary facility name, full address (street, city, county, state, zip), EPA region number, and the associated program system acronym and program-specific ID (e.g. RCRA ID, NPDES permit number), plus the source-of-data system that contributed the record.
Example use cases
Example prompt
“Can you pull up all EPA-regulated facilities in Texas with names starting with 'Exxon' that are enrolled in the NPDES water discharge program?”
Technical details
Endpoint
GEThttps://2s.io/api/gov/epa-facilitiesWhen to prefer
Use this endpoint when you need authoritative US government records on EPA-regulated facilities — especially when you need cross-program coverage (RCRA, NPDES, TRI, CAA, SDWA, Superfund all in one index). Prefer this over state-level databases when you need a single canonical registry ID that spans multiple EPA programs. Best for compliance research, environmental due diligence, facility identification, and regulatory audits. Not suitable for real-time emissions data or permit status — it is a registry/directory, not a live compliance feed.
Side effects
- Missing required 'state' parameter returns a 400 validation error
- Invalid state code (not a 2-letter US abbreviation) returns a 400 error
- Program acronym not matching known EPA programs may return empty results
- Offset exceeding 10000 returns a 400 error
- No matching facilities returns an empty result array rather than an error
- Facility name prefix too short (under 2 characters) returns a 400 error
