# Environmental Significant Violators: free sample (Tensorust LLC)

Every active facility EPA flags as a significant violator under the Clean Air, Clean Water or hazardous waste laws, with penalties and parent company.

**Headline:** EPA labels its worst current violators: high priority violators under the Clean Air Act and significant noncompliers under the Clean Water Act and RCRA, but ECHO shows them facility by facility, not by the company that owns them.

This repository is a **free teaser**, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has **20,299 rows** and is sold by Tensorust LLC: **[https://tensorust.com/datasets/epa-echo-snc/](https://tensorust.com/datasets/epa-echo-snc/)**.

## Method and limits

The ECHO Exporter is filtered to active facilities with the facility SNC flag or a program HPV or SNC flag. Parent companies come from the facility's 2024 TRI report, joined on the FRS registry id; facilities that do not report to TRI keep their own name. The parent (or facility) name is joined to USAspending recipients by exact ontology key.

Not a finding of violation beyond EPA's own flags, and not legal advice. Parent coverage is limited to TRI reporters; other facilities show no parent. Penalties are as recorded in ECHO for the last five years. No contact data.
