Updated November 7, 2026. Read from US EPA, Enforcement and Compliance History Online (ECHO). Public domain (U.S. government work). Counts and penalties cover the five years to November 1, 2026 as ECHO publishes them in its exporter and case downloads, drawn from EPA's air, water, hazardous waste and drinking water systems and from the states that report to them. Records can be incomplete, late or corrected after this page was read. A federal case penalty that names several facilities is shown on each of them and counted once in industry, state and national totals. Each row links to EPA's own report. A quarter in significant noncompliance is EPA's term for a serious violation status in a program, not a finding of fault beyond that status.
