Understanding EPA ECHO Violations, SNC Status, and Federal Penalties

What does 'Significant Non-Compliance (SNC)' or '12 Quarters in Non-Compliance' actually mean on an EPA facility record? Plain-English breakdown of federal environmental enforcement.

Tracked Facility vs. Active Violator vs. SNC

Not every facility in the U.S. EPA database is polluting. Over 70% of registered facilities simply hold routine operating permits with zero violations. However, when a facility exceeds permitted emission or discharge limits, fails mandatory inspections, or violates hazardous waste storage rules, EPA marks quarters of non-compliance. The most severe designation is Significant Non-Compliance (SNC) or High Priority Violation (HPV).

Why Our Calibrated 0–100 Risk Score Separates Routine Permits from Real Hazards

Raw government spreadsheets treat a compliant neighborhood pharmacy with a small hazardous-waste manifest ID the same as a chemical refinery under federal consent decree. FullPropertyReport's calibrated 0–100 scoring model weights SNC status, quarters in non-compliance, formal enforcement actions, and monetary penalties so genuine high-risk sites stand out immediately.

Frequently Asked Questions

Does an EPA Registry ID mean a business contaminated the soil?
No. An EPA Registry ID simply means the site is regulated or permitted under federal/state environmental programs. Always check the Risk Tier, Compliance Status, and Quarters in Non-Compliance.
