EPA discharge permits and enforcement history
Every permitted discharger upstream of you, with their compliance history.
EPA discharge permits tell you who is legally putting something into the water above you, and the enforcement record tells you who has been doing it wrong. Both are public, both are hard to map, and both change what a downstream right is worth.

Why EPA Discharge Permits matters
A discharge permit upstream is both a risk to your water quality and a precedent for your own permit. Buyers regularly discover an enforcement history two miles upstream only after closing, and it changes both the treatment design and the negotiating position.
Questions EPA Discharge Permits answers
- Who is permitted to discharge upstream of my intake?
- Does any nearby facility have a pattern of violations?
- What is the permitting precedent for a discharge like the one I need?
What is in the EPA Discharge Permits data
Coverage: Permitted facilities across the western US. Source dataset: ECHO — Enforcement and Compliance History Online (NPDES).
| Field | What it tells you |
|---|---|

| Compliance status | Current status including significant noncompliance flags. |
| Enforcement history | Formal actions and penalties on record. |
How we serve EPA Discharge Permits
ECHO facilities are pulled on a weekly cadence with compliance flags carried through intact, so a facility in significant noncompliance is visually distinct from one merely holding a permit.
