EPA ECHO is free and covers four major environmental laws, and 1Lookup returns one answer for a company for $0.015 when a facility is found.

Looking up the EPA's compliance and enforcement records for the facilities it regulates. ECHO stands for Enforcement and Compliance History Online. It covers facilities regulated under the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act and the Safe Drinking Water Act, and it searches facilities by name or ID, by city, state or zip code and by program, and civil and criminal enforcement cases by company name, docket number and more.

It is free. The site's pages list no plan, quota or charge, and the FAQ says ECHO does not require users to log in. The web services return XML, JSON or JSONP, the web services page lists no key, registration or rate limit, and the page points anyone downloading a large volume to the ECHO data downloads. Checked October 2026.

3 credits per company with a facility found, free when no EPA-regulated facility matches. On the Starter plan ($99 a month for 20,000 credits) a check is about $0.015, which covers 6,666 companies a month and is $14.85 per 1,000. At the Enterprise end of the rate card it is about $0.006. EPA ECHO is the cheaper bill: it is free, against $99 for a Starter month.

ECHO returns facility rows, and the name search is loose: the Corporate Compliance Screener page warns it may over-select records that sound like the name, and gives DuPont returning a facility in Dupont, WA as its example, so you deselect the false positives before you generate a report. 1Lookup keeps only the active facilities whose own name carries every word you sent, adds the counts and penalties across them, and returns how many facilities the EPA returned in all beside how many carried the name, so a look-alike is never counted as the company's.

On price, breadth and depth. It is free, it needs no login, and it searches by program (air, wastewater, biosolids, stormwater, hazardous waste and drinking water) and searches civil and criminal enforcement cases, not only a company's facilities by name. The Corporate Compliance Screener takes several company, subsidiary and trade-style names at once and downloads CSV and Excel files, the ECHO Exporter is a download of more than 1.5 million regulated facilities with over 130 data fields each, and ECHO Notify sends weekly alerts. 1Lookup lists the ten riskiest matching facilities, not every one.

ECHO's FAQ says its data are generally updated weekly, with exceptions: Safe Drinking Water Act data are updated quarterly, and real-time data are not presented. 1Lookup reads the same records when you look a company up, and says the day it read them in checked_at. A repeat lookup of the same company by the same user within 7 days comes from the cache at no charge.

Neither finds them by owner. The ECHO FAQ says ECHO does not contain any corporate linkage data, and the Corporate Compliance Screener page says it does not provide corporate family linkages. 1Lookup matches a facility by its own name too, so a parent company's sites filed under other names are not found, and the answer says to confirm the facilities are the sites you mean. Try each trade name as its own lookup.

Yes, in both. The Corporate Compliance Screener takes several names separated by semicolons and returns one report you review and download. 1Lookup takes a CSV with a company column, adds a state after the name when you want one, and returns a row per company with its counts and verdict, billed per company with a facility found, with a row that finds nothing free.

If you want the EPA's raw records for free and can sort out the look-alike facilities, ECHO is the simplest source, and nothing beats it on price. If you want one company as a finished answer, with the totals added up and a verdict, and a bulk CSV on one balance that also pays for phone, email and IP checks, 1Lookup's Environmental Compliance Check bills 3 credits only when a facility is found.

If you want the EPA's records for nothing, or the depth that sits behind a facility, such as enforcement cases, program reports and nationwide downloads, yes. The FAQ says information for larger facilities is much more complete than for smaller ones and that EPA cannot positively state that a facility without violations in ECHO is fully compliant, so read it as what the EPA's records show. If you want a company's facilities added up in one call, compare the per-lookup price of 1Lookup.
