EPA Enforcement and Compliance History Online (ECHO), weekly national export. Counts cover active sites in the Facility Registry Service; inspections, formal actions and penalties cover the last five years, quarters in violation the last three years. The EPA attributes a case that covers several facilities to each of them; area penalty totals here count an amount shared through the same federal case once, facility figures show the amount attributed to that facility. Large facilities are Clean Air Act majors, Clean Water Act majors and large hazardous waste generators or handlers. Source record.
