EPA’s Enforcement and Compliance History Online (ECHO) is a public warehouse. It is not a live feed of every inspector in the field. About once a week, EPA publishes a bulk ECHO Exporter snapshot. SNCAlert diffs that file against the prior week and emails desks when a facility newly shows Significant Noncompliance (SNC), High Priority Violation (HPV), or a new formal action or penalty.
That “newly” is the product. A site that has sat in SNC for two years is already on every mature target list. A site that flipped this Saturday’s refresh is a reason to write the first email this Monday.
What SNC and HPV actually are
SNC is the Clean Water Act and RCRA label for a serious, unresolved compliance problem. HPV is the Clean Air Act counterpart. They are program status flags inside ECHO, derived from EPA and authorized-state data. They are not a court judgment, not a Phase I Environmental Site Assessment, and not a substitute for reading the Detailed Facility Report (DFR) and the source systems behind it.
ECHO lags. Source systems are incomplete. EPA says so in its own data notes. Treat a flip as a reason to look, not as a legal conclusion you can put in a proposal.
What a BD desk should do with a flip
- Confirm the program (CAA / CWA / RCRA) and the event type.
- Open the ECHO DFR. Read the last inspection, the last formal action, and whether a penalty amount is published.
- Match NAICS and geography to the services you actually sell — wastewater, air permitting, hazardous waste, or enforcement defense.
- Write to the owner or operator as a compliance conversation, not as “EPA just fined you.” The snapshot may be late or incomplete.
SNCAlert’s public teaser shows name and state only. The subscribed desk list adds street, ZIP, NAICS, program, penalty dollars when present, and the DFR link. That split exists so the homepage is not a free nationwide skip-trace.
What not to do
Do not present an SNCAlert row as EPA advice. Do not skip the DFR. Do not treat a missing penalty field as “no money involved.” Do not use the list as Phase I due diligence for a real-estate close.
