## What this site is NOT

- This is not the official register and does not replace consulting it.
- Holding a licence is the minimum legal requirement, not a quality mark.
- Facility-level EPA compliance records (ECHO): air, water, hazardous waste, drinking water.
- Counts cover the last five years as computed by ECHO; an absence of records is not proof of compliance.
- This site ranks no one.

## Privacy

Facilities whose name designates a private person are searchable but not listed on any indexable page.
