EPA ECHO CWA Facilities Scraper — State Rosters

What this Actor scrapes

EPA's ECHO (Enforcement and Compliance History Online) publishes every Clean Water Act–regulated facility, but pulling a full state roster means correctly handling ECHO's undocumented two-call protocol — a JSON search call that returns a query ID, then a single CSV download call that streams the entire result set at once with no server-side pagination. This Actor runs both calls, branches correctly on a match, a zero-match, or a rejected search, and flattens every facility — name, address, registry ID, county, EPA region, permit status — into one billable row.

What we handle for you

• 🧭 The two-call protocol, done right — one JSON search call, one CSV download call, exactly as ECHO expects. No guessed query params.
• 🧱 Zero matches is a clean success, not a failure — a narrow state/name combination finishes SUCCEEDED with a status message, never a false FAILED run.
• 🛡️ We rotate browser fingerprints (curl-cffi impersonation — Chrome/Firefox/Safari) on every request.
• 🔁 Retries with exponential backoff on 429 / 5xx, honouring Retry-After — up to 5 attempts per call.
• 🧊 Clean, typed dataset rows — Pydantic-validated, one malformed CSV row skipped and logged, never an aborted run.
• 💰 Pay-Per-Event pricing — you only pay for results that hit your dataset.

Use cases

• ESG and environmental due diligence — pull every CWA-regulated facility in a state before a site acquisition or portfolio review.
• Compliance monitoring — track permit status (e.g. Effective, Administratively Continued) across a jurisdiction.
• Market research — size the number of regulated dischargers by state or county.
• Lead generation for environmental consultancies and permit-renewal services.

Input

Paste this into the Apify Console, or send it as the run input over the API. Proxy settings are on by default; you rarely need to touch them.

}

Output

One row per result, schema-validated before it is written. Export JSON, CSV, Excel or XML from the run, or read it over the API.

You pay only for results that land. Cap any run with maxTotalChargeUsd. See pricing & billing for worked examples.

Limitations

• Clean Water Act (CWA) facilities only — Air (CAA), RCRA, and Safe Drinking Water Act programs are separate ECHO products, out of scope for v1.
• No violation/inspection/penalty history — this Actor returns current facility and permit status, not enforcement records.
• No county-level query filter — ECHO silently no-ops unrecognized filter params, so county narrowing isn't offered; county remains in the output.
• Large states (e.g. California, ~30,000+ rows) return a correspondingly large CSV in one response — use maxResults and facilityName to narrow.
